                               PROSPECTUS SUMMARY
 
    Priceline.com has pioneered a unique new type of e-commerce known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price," we collect consumer demand, in the form of
individual customer offers guaranteed by a credit card, for a particular product
or service at a price set by the customer. We then either communicate that
demand directly to participating sellers, or access participating sellers'
private databases to determine whether we can fulfill the customer's offer on
the basis of the pricing information and rules established by the sellers.
Consumers agree to hold their offers open for a specified period of time and,
once fulfilled, offers cannot be canceled. By requiring consumers to be flexible
with respect to brands, sellers and/or product features, we enable sellers to
generate incremental revenue without disrupting their existing distribution
channels or retail pricing structures.
 
    We commenced the priceline.com service on April 6, 1998 with the sale of
leisure airline tickets and expanded the priceline.com service to include the
sale of new automobiles, on a test basis, in July 1998, hotel room reservations
in October 1998 and home mortgages in January 1999. With respect to airline and
hotel reservation services, we earn the spread between the customer's named
price and the fare or rate charged by the seller. With respect to our automobile
and mortgage services, and for our adaptive marketing programs, we earn fees or
other payments payable by the seller and/or the customer or by our adaptive
marketing partners.
 
    We believe that the priceline.com service already has achieved significant
consumer acceptance and widespread brand awareness. During the period from
launch through December 31, 1998, we collected guaranteed offers for
approximately 1.9 million airline tickets, representing approximately $400.0
million in total consumer demand. This demand resulted in sales of approximately
134,900 airline tickets, representing approximately $30.4 million in revenue. We
intend to continue to leverage the priceline.com brand over the next two years
by expanding our product offerings to include other leisure travel products,
other financial services products and a number of retail products. Our seller
participants currently include 18 domestic and international airlines and
several nationally recognized hotel chains.

                                  RISK FACTORS
 
    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS BEFORE MAKING AN
INVESTMENT DECISION. THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE DUE TO
ANY OF THESE RISKS, AND YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT. YOU ALSO
SHOULD REFER TO THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, INCLUDING
OUR COMBINED FINANCIAL STATEMENTS AND THE RELATED NOTES THERETO.
 
    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS. THESE STATEMENTS RELATE
TO FUTURE EVENTS OR FUTURE FINANCIAL PERFORMANCE. IN SOME CASES, YOU CAN
IDENTIFY FORWARD-LOOKING STATEMENTS BY TERMINOLOGY SUCH AS "MAY," "WILL,"
"SHOULD," "COULD," "EXPECTS," "PLANS," "ANTICIPATES," "BELIEVES," "ESTIMATES,"
"PREDICTS," "POTENTIAL," OR "CONTINUE" OR THE NEGATIVE OF SUCH TERMS AND OTHER
COMPARABLE TERMINOLOGY. THESE STATEMENTS ARE ONLY PREDICTIONS. IN EVALUATING
THESE STATEMENTS, YOU SHOULD SPECIFICALLY CONSIDER VARIOUS FACTORS, INCLUDING
THE RISKS OUTLINED BELOW. THESE FACTORS MAY CAUSE OUR ACTUAL RESULTS TO DIFFER
MATERIALLY FROM ANY FORWARD-LOOKING STATEMENT. SEE "SPECIAL NOTE REGARDING
FORWARD-LOOKING STATEMENTS."
 
OUR LIMITED OPERATING HISTORY MAKES EVALUATING OUR BUSINESS DIFFICULT
 
    Priceline.com was formed in July 1997 and began operations on April 6, 1998.
As a result, we have only a limited operating history on which you can base an
evaluation of our business and prospects. Our prospects must be considered in
the light of the risks, uncertainties, expenses and difficulties frequently
encountered by companies in their early stages of development, particularly
companies in new and rapidly evolving markets, such as online commerce, using
new and unproven business models. To address these risks and uncertainties, we
must, among other things:
 
    - attract leading sellers and consumers to the priceline.com service;
 
    - maintain and enhance our brand, and expand our product and service
      offerings;
 
    - attract, integrate, retain and motivate qualified personnel; and
 
    - adapt to meet changes in our markets and competitive developments.
 
We may not be successful in accomplishing these objectives.
 
WE ARE NOT PROFITABLE AND EXPECT TO CONTINUE TO INCUR LOSSES
 
    We have incurred net losses of $49.0 million during the period from July 18,
1997 (inception) through December 31, 1998, before giving effect to $67.9
million of non-cash charges arising from equity issuances to a number of our
participating airlines, our chief executive officer and other parties, which
resulted in total net losses of $116.9 million for the period. We have not
achieved profitability and expect to continue to incur losses for the
foreseeable future. The principal causes of our losses are likely to continue to
be significant brand development costs, marketing and promotion costs and
technology and systems development costs.
 
    Almost all of our revenues to date have been derived from airline ticket
sales and related adaptive marketing programs. In order to increase airline and
adaptive marketing revenues, build a record of successful transactions and
enhance the priceline.com brand, we have sold a substantial portion of our
airline tickets below cost. In addition, as our business model evolves, we
expect to introduce a number of new products and services. With respect to both
current and future product and service offerings, we expect to increase
significantly our operating expenses in order to increase our customer base,
enhance our brand image and support our growing infrastructure. For us to make a
profit, our revenues and gross profit margins will need to increase sufficiently
to cover these and other future costs. Otherwise, we may never make a profit.
 
                                       3
 
WE ARE DEPENDENT ON ADAPTIVE MARKETING PROGRAMS
 
    Our adaptive marketing programs permit consumers to increase the amount of
their offers at no additional cost by participating in sponsor promotions during
the process of making an offer through the priceline.com service. The fees paid
to us by sponsors offering the promotions generate significant revenues. Since
these fees have no direct costs, they have a disproportionately positive impact
on our gross profit margins. A significant reduction in consumer acceptance of
our adaptive marketing programs or any other material decline in such programs
could result in a material reduction in our revenues and our gross profit. We
may not be able to replace such revenues through other programs or through
product sales.
 
    Currently, almost all of our adaptive marketing revenues are derived from
fees paid by Capital One Bank for qualifying credit card applications submitted
over the priceline.com service in connection with customer offers for airline
tickets. On March 3, 1999, Capital One exercised its contractual option to cease
accepting credit card applications through priceline.com effective May 1, 1999
unless we enter into a new agreement with them on revised terms which they have
offered to us.
 
   
    We have entered into an agreement in principle with First USA Bank, a
leading national credit card issuer, under which First USA would replace Capital
One as our strategic partner in our credit card adaptive marketing program.
Under the First USA adaptive marketing program, we would enable our customers to
increase the amount of their offers by a specified amount by applying online for
a First USA credit card and would offer other promotions linked to the First USA
customer acquisition program. We would earn fees in a variety of ways, including
(1) upon the acceptance by First USA of credit card applications submitted
through the priceline.com service, up to a specified maximum amount of five
million accepted applications, subject to reduction under certain circumstances
by First USA, (2) upon the activation of credit card accounts acquired for First
USA through the priceline.com service and based upon the use of such accounts
and (3) for transfers of balances from other credit cards to First USA credit
cards through the priceline.com service. The First USA agreement would have a
term of five years, subject to certain termination and repricing provisions.
    
 
    While we expect to enter into a definitive agreement with First USA, there
can be no assurance that such an agreement will in fact be executed, or that the
terms of any such agreement will be substantially the same as, or similar to,
those contemplated in the agreement in principle. Moreover, we can give no
assurance that a new adaptive marketing credit card program with First USA or
any other credit card issuer will be established by the expiration of the
Capital One program or that it will provide us with financial benefits
comparable to those provided under the Capital One program. Capital One
currently pays a fee for each qualifying credit card application submitted over
the priceline.com service. The fee structure of the First USA program is based
on the factors described above which may or may not result in revenues
comparable to those under the Capital One program. If we fail to secure a new
adaptive marketing program with First USA or another credit card issuer, our
revenues and gross margin are likely to decrease significantly, which could
materially and adversely affect our business and prospects.
 
POTENTIAL FLUCTUATIONS IN OUR FINANCIAL RESULTS MAKES FINANCIAL FORECASTING
  DIFFICULT
 
    We expect our revenues and operating results to vary significantly from
quarter to quarter. As a result, quarter to quarter comparisons of our revenues
and operating results may not be meaningful. In addition, due to our limited
operating history and our new and unproven business model, we cannot predict our
future revenues or results of operations accurately. It is likely that in one or
more future quarters our operating results will fall below the expectations of
securities analysts and investors. If this happens, the trading price of our
common stock would almost certainly be materially and adversely affected.
 
    Our business has no backlog and almost all of our net revenues for a
particular quarter are derived from transactions that are both initiated and
completed during that quarter. Our current and future expense levels are based
largely on our investment plans and estimates of future revenues and are, to a
large extent, fixed. Accordingly, we may be unable to adjust spending in a
timely manner to compensate for
 
                                       4
 
any unexpected revenue shortfall, and any significant shortfall in revenues
relative to our planned expenditures could have an immediate adverse effect on
our business and results of operations.
 
    Our limited operating history and rapid growth makes it difficult for us to
assess the impact of seasonal factors on our business. Nevertheless, we expect
our business to be subject to seasonal fluctuations, reflecting a combination of
seasonality trends for the products and services offered by the priceline.com
service and seasonality patterns affecting Internet use. For example, with
regard to our travel products, demand for leisure travel may increase over
summer vacations and holiday periods, while Internet usage may decline during
the summer months. Our results also may be affected by seasonal fluctuations in
the inventory made available to the priceline.com service by participating
sellers. Airlines, for example, typically enjoy high demand for tickets through
traditional distribution channels for travel during Thanksgiving and the
year-end holiday period. As a result, during those periods, airlines may have
less excess inventory to offer through the priceline.com service at discounted
prices. Our business also may be subject to cyclical variations for the products
and services offered; for example, leisure travel and home mortgage financing
tend to decrease in economic downturns.
 
WE ARE DEPENDENT ON THE AIRLINE INDUSTRY AND CERTAIN AIRLINES
 
    Our near term, and possibly long term, prospects are significantly dependent
upon our sale of leisure airline tickets. Sales of leisure airline tickets and
revenues derived from related adaptive marketing programs represented
essentially all of our revenues for the year ended December 31, 1998. Leisure
travel, including the sale of leisure airline tickets, is dependent on personal
discretionary spending levels. As a result, sales of leisure airline tickets and
other leisure travel products tend to decline during general economic downturns
and recessions. Unforeseen events, such as political instability, regional
hostilities, increases in fuel prices, travel-related accidents and unusual
weather patterns also may adversely affect the leisure travel industry. As a
result, our business also is likely to be affected by those events.
Significantly reducing our dependence on the airline and travel industries is
likely to take a long time and there can be no guarantee that we will succeed in
reducing that dependence.
 
   
    Sales of airline tickets from priceline.com's three largest airline
suppliers accounted for approximately 95% of airline ticket revenue for the year
ended December 31, 1998. As a result, currently we are substantially dependent
upon the continued participation of these three airlines in the priceline.com
service in order to maintain and continue to grow our total airline ticket
revenues. We currently have 18 participating airlines. However, our airline
participation agreements:
    
 
    - do not require the airlines to make tickets available for any particular
      routes;
 
    - do not require the airlines to provide any specific quantity of airline
      tickets;
 
    - do not require the airlines to provide particular prices or levels of
      discount;
 
    - do not require the airlines to deal exclusively with us in the public sale
      of discounted airline tickets; and
 
    - generally, can be terminated upon relatively short notice.
 
    These agreements also outline the terms and conditions under which ticket
inventory provided by the airlines may be sold. In addition, our agreement with
Delta Air Lines requires, subject to various exceptions, Delta's approval of the
addition of new carriers to the priceline.com service and restricts both the
volume of tickets that may be sold and the routes for which tickets may be
offered by specified carriers through the priceline.com service. Accordingly,
Delta could limit our ability to expand our business through the introduction of
new carriers or the expansion of the routes for which we offer tickets.
 
    Due to our dependence on the airline industry, we could be severely affected
by changes in that industry, and, in many cases, we will have no control over
such changes or their timing. For example, if the Federal Aviation
Administration grounded a popular aircraft model, excess seat capacity could be
 
                                       5
 
dramatically reduced and, as a result, our source of inventory could be
significantly curtailed. In addition, given the concentration of the airline
industry, particularly in the domestic market, major airlines that are not
participating in the priceline.com service could exert pressure on other
airlines not to supply us with tickets. Alternatively, the airlines could
attempt to establish their own buyer-driven commerce service or other similar
service to compete with us. We also could be materially adversely affected by
the bankruptcy, insolvency or other material adverse change in the business or
financial condition of one or more of our airline participants.
 
OUR BUSINESS MODEL IS NOVEL AND UNPROVEN
 
    The priceline.com service is based on a novel and unproven business model.
We will be successful only if consumers and sellers actively use the
priceline.com service. Prior to the launch of the priceline.com service,
consumers and sellers had never bought and sold products and services through a
demand collection system over the Internet. Therefore, it is impossible to
predict the degree to which consumers and sellers will use the priceline.com
service.
 
    Many of the factors influencing consumers' and sellers' willingness to use
the priceline.com service are outside our control. For example, a labor dispute
that disrupts airline service or an airline accident could make consumers
unwilling to use a service like priceline.com that does not permit the customer
to designate the airline on which the customer purchases a ticket. In addition,
a breach of security on the Internet, even if we were not involved, could make
consumers unwilling to guarantee orders online with a credit card. Consequently,
it is possible that consumers and sellers will never utilize the priceline.com
service to the degree necessary for us to achieve profitability.
 
WE NEED TO SELL NEW PRODUCTS AND SERVICES
 
    We are unlikely to make significant profits unless we make new or
complementary products and services and a broader range of existing products and
services available through the priceline.com service. We will incur substantial
expenses and use significant resources in trying to expand the type and range of
the products and services that we offer. However, we may not be able to attract
sellers to provide such products and services or consumers to purchase such
products and services through the priceline.com service. In addition, if we
launch new products or services and they are not favorably received by
consumers, our reputation and the value of the priceline.com brand could be
damaged.
 
    Almost all of our experience to date is in the travel industry. The travel
industry is characterized by "expiring" inventories. For example, if not used by
a specific date, an airline ticket or hotel room reservation has no value. The
expiring nature of the inventory creates incentives for airlines and hotels to
sell seats or room reservations at reduced rates. Because we have only limited
experience in selling "non-expiring" inventories on the priceline.com service,
such as new cars or financial services, we cannot predict whether the
priceline.com business model can be successfully applied to such products and
services.
 
OUR BRAND MAY NOT ACHIEVE THE BROAD RECOGNITION NECESSARY TO SUCCEED
 
    We believe that broader recognition and a favorable consumer perception of
the priceline.com brand are essential to our future success. Accordingly, we
intend to continue to pursue an aggressive brand-enhancement strategy, which
will include mass market and multimedia advertising, promotional programs and
public relations activities. These initiatives will involve significant expense.
If our brand enhancement strategy is unsuccessful, these expenses may never be
recovered and we may be unable to increase future revenues. Successful
positioning of the priceline.com brand will largely depend on:
 
    - the success of our advertising and promotional efforts;
 
    - an increase in the number of successful transactions on the priceline.com
      service; and
 
                                       6
 
    - the ability to continue to provide high quality customer service.
 
    We believe that consumers currently associate the priceline.com brand
primarily with the sale of discount airline tickets. To grow our business, we
will need to expand awareness of the priceline.com brand to a wide range of
products and services.
 
    Sales and marketing expense was $24.4 million during the year ended December
31, 1998. To increase awareness of the priceline.com brand and expand it to a
wide range of products and services, we will need to continue to spend
significant amounts on advertising and promotions. These expenditures may not
result in a sufficient increase in revenues to cover such advertising and
promotions expenses. In addition, even if brand recognition increases, the
number of new users or the number of transactions on the priceline.com service
may not increase. Also, even if the number of new users increases, those users
may not use the priceline.com service on a regular basis.
 
WE FACE POTENTIAL CONFLICTS OF INTEREST RELATING TO WALKER DIGITAL
 
    Because of our relationship with Walker Digital and our interlocking
directors, officers and stockholders, we are likely to face potential conflicts
of interest relating to Walker Digital.
 
    The priceline.com service and the business model and related intellectual
property rights underlying the priceline.com service were developed in part by
executives, employees and/or consultants associated with Walker Digital
Corporation, a technology research and development company that was founded and
is controlled by Mr. Jay S. Walker, who is the Founder and Vice Chairman of
priceline.com. Such individuals assigned all of their intellectual property
rights relating to the priceline.com service to Walker Digital's affiliate,
Walker Asset Management Limited Partnership. Walker Asset Management,
subsequently transferred the patent rights relating to the priceline.com service
and other related intellectual property rights to us. We, in turn, granted
Walker Digital a perpetual, non-exclusive, royalty-free right and license to use
certain intellectual property related to the priceline.com service for
non-commercial internal research and development purposes.
 
    Walker Digital also provides us with, among other things, a right to
purchase at fair market value any intellectual property that is in process or
has been fully developed and that is owned and subsequently acquired, developed
or discovered by Walker Digital or Walker Asset Management that will provide
significant value in the use or commercial exploitation of the initially
transferred patent and related intellectual property rights.
 
   
    Walker Digital also provides us with various services, including (1)
research and development assistance; (2) patent and other intellectual property
services; and (3) technical support. Walker Digital also subleases a portion of
its Stamford, Connecticut facilities to us on a month-to-month basis.
Priceline.com, in turn, provides Walker Digital with various management and
administrative services. We also have guaranteed Walker Digital's obligations
under a lease whereby it leases office space that is used by both companies.
    
 
   
    Certain of our executive officers and other key employees also are
directors, officers or employees of Walker Digital and either own, or hold an
option to purchase, equity securities of Walker Digital. Upon the consummation
of this offering, Walker Digital also will own directly approximately 5.3% of
our outstanding common stock. Accordingly, conflicts of interest may arise from
time to time between us and Walker Digital, particularly with respect to the
potential purchase by us of additional intellectual property rights at fair
market value and the pursuit of overlapping corporate opportunities. We have not
adopted any formal plan or arrangement to address such potential conflicts of
interest and intend to review related-party transactions with Walker Digital on
a case-by-case basis. Additionally, the option agreements for priceline.com
options held by many other employees and consultants of priceline.com provide
that options scheduled to vest as of the end of the current vesting period in
which such employee or consultant terminates his or her employment or consulting
relationship with priceline.com will not be forfeited if the
    
 
                                       7
 
employee or consultant leaves priceline.com to work for an entity in which Mr.
Jay S. Walker is the controlling stockholder and maintains such employment until
the end of such current vesting period.
 
    Because we have interlocking directors and officers with Walker Digital,
there may be inherent conflicts of interest when such directors and officers
make decisions related to transactions between us and Walker Digital. We could
lose valuable management input from such conflicted directors and officers.
 
    Mr. Jay S. Walker, as the Founder of Walker Digital and as our Founder, has
performed an essential role in the establishment and development of the
priceline.com service. Mr. Walker also serves as Chairman of Walker Digital and
as non-executive Chairman of NewSub Services, Inc., a direct marketing company
also co-founded by him. Mr. Walker devotes, and expects to continue to devote, a
substantial portion of his time to Walker Digital and a lesser portion of his
time to NewSub Services. Mr. Walker has not committed to devote any specific
percentage of his business time to us. In July 1998, Mr. Richard S. Braddock
replaced Mr. Walker as our Chairman and Chief Executive Officer. As a result,
Mr. Walker's role with priceline.com has been reduced, and we expect that Mr.
Walker will continue to reduce his involvement with us over time. Mr. Walker's
skills and experience have benefitted, and continue to benefit, us
significantly. Priceline.com could lose valuable management expertise as Mr.
Walker further reduces his day-to-day involvement with priceline.com.
 
WE MAY BE UNABLE TO EFFECTIVELY MANAGE OUR RAPID GROWTH
 
    We have rapidly and significantly expanded our operations and anticipate
that further expansion will be required to realize our growth strategy. Our
rapid growth has placed significant demands on our management and other
resources which, given our expected future growth rate, is likely to continue.
To manage our future growth, we will need to attract, hire and retain highly
skilled and motivated officers and employees and improve existing systems and/or
implement new systems for: (1) transaction processing; (2) operational and
financial management; and (3) training, integrating and managing our growing
employee base.
 
IF WE LOSE OUR KEY PERSONNEL OR CANNOT RECRUIT ADDITIONAL PERSONNEL, OUR
  BUSINESS MAY SUFFER
 
    Competition for personnel with experience in Internet commerce is intense.
If we do not succeed in attracting new employees or retaining and motivating our
current and future employees, our business could suffer significantly.
 
   
    Since our formation in July 1997, we have expanded from 10 to 194 employees.
We also have employed many key personnel since our launch in April 1998,
including our Chief Executive Officer, and a number of key managerial,
marketing, planning, financial, technical and operations personnel. In addition,
we currently are engaged in recruiting a new chief operating officer. We expect
to continue to add additional key personnel in the near future. We do not have
"key person" life insurance policies on any of our key personnel.
    
 
    We believe our performance is substantially dependent on;
 
    - our ability to retain and motivate our senior management and other key
      employees; and
 
    - our ability to identify, attract, hire, train, retain and motivate other
      highly skilled technical, managerial, marketing and customer service
      personnel.
 
                                       8
 
CAPACITY CONSTRAINTS AND SYSTEM FAILURES COULD HARM OUR BUSINESS
 
    If our systems cannot be expanded to cope with increased demand or fail to
perform, we could experience:
 
    - unanticipated disruptions in service;
 
    - slower response times;
 
    - decreased customer service and customer satisfaction; or
 
    - delays in the introduction of new products and services;
 
any of which could impair our reputation, damage the priceline.com brand and
materially and adversely affect our revenues.
 
    We use internally developed systems to operate the priceline.com service,
including transaction processing and order management systems that were designed
to be scalable. However, if the number of users of the priceline.com service
increases substantially, we will need to significantly expand and upgrade our
technology, transaction processing systems and network infrastructure. We do not
know whether we will be able to accurately project the rate or timing of any
such increases, or expand and upgrade our systems and infrastructure to
accommodate such increases in a timely manner.
 
    Our ability to facilitate transactions successfully and provide high quality
customer service also depends on the efficient and uninterrupted operation of
our computer and communications hardware systems. The priceline.com service has
experienced periodic system interruptions, which we believe will continue to
occur from time to time. Our systems and operations also are vulnerable to
damage or interruption from human error, natural disasters, power loss,
telecommunication failures, break-ins, sabotage, computer viruses, intentional
acts of vandalism and similar events. While we currently maintain redundant
servers at our Stamford, Connecticut premises to provide limited service during
system disruptions at our production site hosted by Exodus Communications, Inc.,
we do not have fully redundant systems, a formal disaster recovery plan or
alternative providers of hosting services. In addition, we do not carry
sufficient business interruption insurance to compensate for losses that could
occur. Any system failure that causes an interruption in service or decreases
the responsiveness of the priceline.com service could impair our reputation,
damage our brand name and materially adversely affect our revenues.
 
WE RELY ON THIRD-PARTY SYSTEMS
 
    We rely on certain third-party computer systems or third-party service
providers, including;
 
    - the computerized central reservation systems of the airline and hotel
      industries to satisfy demand for airline tickets and hotel room
      reservations;
 
    - the computer systems of LendingTree, Inc. to satisfy offers for home
      mortgages;
 
    - Exodus Communications to host our systems infrastructure, web and database
      servers; and
 
    - CallTech Communications Incorporated to operate our call center.
 
    Any interruption in these third-party services, or a deterioration in their
performance, could be disruptive to our business. We currently do not have any
contractual arrangement with Exodus Communications and our agreements with
CallTech Communications and LendingTree are terminable upon short notice. In the
event our arrangement with any of such third parties is terminated, we may not
be able to find an alternative source of systems support on a timely basis or on
commercially reasonable terms.
 
                                       9
 
INTENSE COMPETITION COULD REDUCE OUR MARKET SHARE AND HARM OUR FINANCIAL
  PERFORMANCE
 
    The markets for the products and services offered on the priceline.com
service are intensely competitive. We compete with both traditional distribution
channels and online services. Increased competition could diminish our ability
to become profitable or result in loss of market share and damage the
priceline.com brand.
 
    We currently or potentially compete with a variety of companies with respect
to each product or service we offer. With respect to travel products, these
competitors include:
 
    - Internet travel agents such as Travelocity, Preview Travel and Microsoft's
      Expedia.com;
 
    - traditional travel agencies;
 
    - consolidators and wholesalers of airline tickets and other travel
      products;
 
    - individual airlines, hotels, rental car companies, cruise operators and
      other travel service providers; and
 
    - operators of travel industry reservation databases such as Worldspan and
      Sabre.
 
Our current or potential competitors with respect to new automobiles include
traditional and online auto dealers, including newly developing auto superstores
such as Auto Nation, Auto-by-Tel and Microsoft's CarPoint. With respect to
financial service products, our competitors include:
 
    - banks and other financial institutions;
 
    - online and traditional mortgage and insurance brokers, including Quicken
      Mortgage, E-Loan and Home Shark; and
 
    - insurance companies.
 
    We also potentially face competition from a number of large online services
that have expertise in developing online commerce and in facilitating Internet
traffic. These potential competitors include America Online, Microsoft and
Yahoo!, who could choose to compete with us either directly or indirectly
through affiliations with other e-commerce companies. Other large companies with
strong brand recognition, technical expertise and experience in online commerce
and direct marketing could also seek to compete in the buyer-driven commerce
market. While we face competition from all of these current or potential
competitors, our business and financial position would be particularly at risk
if the airlines chose to establish their own buyer-driven commerce system to
sell excess inventory.
 
    Many of our competitors have significant competitive advantages. For
example, airlines, hotels, financial institutions and other suppliers also sell
their products and services directly to consumers and have established Web
sites. Internet directories, search engines and large traditional retailers have
significantly greater operating histories, customer bases, technical expertise,
brand recognition and/or online commerce experience than us. In addition,
certain competitors may be able to devote significantly greater resources than
us to:
 
    - marketing and promotional campaigns;
 
    - attracting traffic to their Web sites;
 
    - attracting and retaining key employees; and
 
    - Web site and systems development.
 
                                       10
 
OUR SUCCESS DEPENDS ON OUR ABILITY TO PROTECT OUR INTELLECTUAL PROPERTY
 
    We have developed a comprehensive program for securing and protecting rights
in patentable inventions, trademarks, trade secrets and copyrightable materials.
If we are not successful in protecting our intellectual property, there could be
a material adverse effect on our business.
 
    PATENTS
 
    We currently hold one issued United States patent directed to a unique
Internet-based buyer-driven commerce method and system underlying our business
model. We also hold one issued United States patent directed to a method and
system for pricing and selling airline ticket options and one allowed patent
application directed to methods and systems for generating airline-specified
time tickets. In addition, we have pending eighteen United States and one
international patent applications directed to different aspects of our
technology and business processes. We also have instituted an invention
development program to identify and protect new inventions and a program for
international filing of selected patent applications. Nevertheless, it is
possible that:
 
    - our core buyer-driven commerce patent and any other issued patents could
      be successfully challenged by one or more third parties, which could
      result in our loss of the right to prevent others from exploiting the
      buyer-driven commerce system claimed in the patent or the inventions
      claimed in any other issued patents;
 
    - because of variations in the application of our business model to each of
      our products and services, our core buyer-driven commerce patent may not
      be effective in preventing one or more third parties from utilizing a
      copycat business model to offer the same product or service in one or more
      categories;
 
    - our ability to practice our core buyer-driven commerce patent through
      offering one or more of our products or services could be successfully
      prevented if one or more third parties prevail in an interference action
      in the U.S. Patent and Trademark Office and thereby obtain priority of
      invention for the subject matter claimed in our core buyer-driven commerce
      patent;
 
    - our pending patent applications may not result in the issuance of patents;
      and
 
    - current and future competitors could devise new methods of competing with
      our business that are not covered by our issued patents or patent
      applications.
 
    While our core patent is directed to a unique buyer-driven commerce system
and method, it does not necessarily prevent competitors from developing and
operating Internet commerce businesses that use customer-offer based business
models. It is possible for a competitor to develop and utilize a business model
that appears similar to our patented buyer-driven commerce system, but which has
sufficient distinctions that it does not fall within the scope of our patent.
For example, we are aware of more than one Internet travel service that appear
to use a customer-offer based transaction model, but based on the information we
have obtained to date, may not infringe our patent.
 
    PENDING INTERFERENCE ACTION
 
    On January 6, 1999, we received notice that a third party patent applicant
and patent attorney, Thomas G. Woolston, purportedly had filed in December 1998
with the United States Patent and Trademark Office a request to declare an
"interference" between a patent application filed by Woolston describing an
electronic market for used and collectible goods and our core buyer-driven
commerce patent. We have received a copy of a Petition for Interference from
Woolston, the named inventor in at least three United States Patent applications
titled "Consignment Nodes," one of which has issued as a patent (U.S. Patent
Number: 5,845,265). We currently are awaiting information from the Patent Office
regarding whether it will initiate an interference proceeding concerning
Woolston's patent application and our core buyer-driven commerce patent. An
interference is an administrative proceeding instituted in the
 
                                       11
 
Patent Office to determine questions of patentability and priority of invention
between two or more parties claiming the same patentable invention. There is no
statutory period within which the Patent Office must act on an interference
request. If an interference is declared and proceeds through a final hearing in
the Patent Office, a final judgment is made by the Patent Office as to
inventorship. Following such final judgment, appeals could be made in Federal
court. While there can be no certainty as to time periods, interference
proceedings typically take years to resolve.
 
    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from our
core buyer-driven commerce patent. In order to make this showing, he would have
to prove, among other things, that he invented the subject matter of the
priceline.com claims before the inventors of our patent. If the Patent Office
were to find that Woolston's patent application supported the copied
priceline.com claims, it would resolve the interference by awarding inventorship
to the party with the earliest proven date of invention. Woolston recently
announced an agreement to license his issued patent and pending patent
applications to the owner of an Internet travel service that, according to such
announcement, commenced on-line operations in the fourth quarter of 1998 and
purports to compete with us.
 
   
    While the interference process is still at an early stage, we believe that
we have meritorious defenses to Woolston's claim, which we intend to pursue
vigorously. Among other things, we believe that the Woolston patent application
does not disclose the inventions covered by the priceline.com patent claims.
However, it is impossible to predict the outcome of an interference with
certainty. While Woolston claims to have an earlier invention date by a period
of approximately sixteen months, the final decision as to priority of invention
would be made by the Patent Office after considering facts provided by each
party during the interference proceeding. If an interference is declared and
thereafter resolved in favor of Woolston, such resolution could result in an
award of some or all of the disputed patent claims to Woolston. If, following
such award, Woolston were successful in a patent infringement action against us,
including prevailing over all defenses available to us such as those of
non-infringement and invalidity, this could require us to obtain licenses from
Woolston at a cost which could significantly adversely affect our business. If
Woolston prevailed in both an interference and an infringement action, then we
could be enjoined from conducting business through the priceline.com service to
the extent covered by the patent claims awarded to Woolston. In addition,
defense of the interference action may be expensive and may divert management
attention away from our business.
    
 
    TRADEMARKS, COPYRIGHTS AND TRADE SECRETS
 
    We regard the protection of our copyrights, service marks, trademarks, trade
dress and trade secrets as critical to our future success. We rely on a
combination of laws and contractual restrictions, such as confidentiality
agreements to establish and protect our proprietary rights. However, laws and
contractual restrictions may not be sufficient to prevent misappropriation of
our technology or deter others from developing similar technologies. We also
attempt to register our trademarks and service marks in the United States and
internationally. However, effective trademark, service mark, copyright and trade
secret protection may not be obtainable and/or available in every country in
which our services are made available online.
 
    PENDING LITIGATION
 
   
    On January 19, 1999, a complaint was filed, and on February 22, 1999 an
amended and supplemental complaint was filed, in the United States District
Court for the Northern District of California by Marketel International, Inc., a
California corporation, under the caption MARKETEL INTERNATIONAL INC. V.
PRICELINE.COM ET. AL., No. C-99-1061 (N.D. CA 1999), against priceline.com,
Priceline Travel, Walker Asset Management, Walker Digital, Mr. Jay S. Walker,
our Founder and Vice Chairman, and Mr. Andre Jaeckle, an individual who made a
$1.0 million loan to priceline.com bearing interest at a rate of 6% per year,
and in connection therewith, received warrants, which have subsequently been
fully exercised, to purchase 62,500 shares of our common stock. The amended
complaint filed by Marketel which joins as defendants Mr. Timothy G.
    
 
                                       12
 
Brier, our Executive Vice President, Travel, Mr. Bruce Schneier, an individual
and consultant to Walker Digital, and Mr. James Jorasch, an individual and
employee of Walker Digital alleges causes of action for, among other things,
misappropriation of trade secrets, breach of contract, conversion, breach of
confidential relationship, copyright infringement, fraud, unfair competition,
and false advertising, and seeks injunctive relief and damages in an unspecified
amount. In its amended complaint, Marketel alleges, among other things, that the
defendants conspired to misappropriate Marketel's business model, which it
describes as a buyer-driven electronic marketplace for travel services and its
appurtenant techniques, market research, forms, plans and processes, and which
an executive of Marketel allegedly provided to Messrs. Walker and Jaeckle in
confidence approximately ten years ago. The amended complaint also alleges that
three former Marketel employees are the actual sole inventors or co-inventors of
priceline.com's core buyer driven commerce patent (US patent No. 5794207), which
was issued on August 11, 1998 with Messrs. Jay S. Walker, Bruce Schneier and
James Jorasch listed as the inventors and which patent was assigned to Walker
Digital and thereafter assigned to priceline.com. Marketel asks that the
patent's inventorship be corrected accordingly.
 
    Based upon publicly available information, we believe that Marketel's fax
and fee-based business was launched in 1991 and ceased operations seven months
later. Our Internet-based model was independently developed at Walker Digital
and priceline.com, and practiced by priceline.com starting in 1998. Based on
publicly available information and Marketel's amended complaint, we understand
that Marketel operated a fax-based travel information service which offered
consumers, travel agents and/or consolidators the opportunity to purchase
specially printed forms. These forms, when accompanied by an additional non-
refundable fee, allowed prospective ticket buyers to fax to Marketel credit-card
guaranteed bids for airline travel at a bid price specified by the buyer. We
believe that Marketel has not engaged in any regular commercial activities since
ceasing operations in 1992. Based upon publicly available information, Marketel
reactivated its active status as a corporation by satisfying its back-due tax
obligations to the State of California shortly after the filing of the original
complaint.
 
    On February 5 and February 10, 1999, the defendants filed their answer and
amended answer, respectively, in which they denied the material allegations of
liability in the amended complaint. We and all other defendants strongly dispute
the material legal and factual allegations contained in Marketel's amended
complaint and believe that the amended complaint is without merit. We intend to
defend vigorously against the action. However, defending the law suit may
involve significant expense and, due to the inherent uncertainties of
litigation, there can be no certainty as to the ultimate outcome.
 
    Pursuant to the indemnification obligations contained in the Purchase and
Intercompany Services Agreement with Walker Digital, Walker Digital has agreed
to indemnify, defend and hold harmless priceline.com for damages, liabilities
and legal expenses incurred in connection with the Marketel litigation.
 
    DOMAIN NAMES
 
    We currently hold the Internet domain name "priceline.com," as well as
various other related names. Domain names generally are regulated by Internet
regulatory bodies. The regulation of domain names in the United States and in
foreign countries is subject to change. Regulatory bodies could establish
additional top-level domains, appoint additional domain name registrars or
modify the requirements for holding domain names. As a result, we may not
acquire or maintain the "priceline.com" domain name in all of the countries in
which we conduct business.
 
    The relationship between regulations governing domain names and laws
protecting trademarks and similar proprietary rights is unclear. Therefore, we
could be unable to prevent third parties from acquiring domain names that
infringe or otherwise decrease the value of our trademarks and other proprietary
rights.
 
                                       13
 
    LICENSES
 
    In the future, we may license portions of our intellectual property,
including our issued patents, to third parties. To date, we have granted a small
business providing online travel services immunity from suit under our core
Internet-based buyer-driven commerce system patent, on the condition that the
nature and scope of such business is not significantly changed. If the nature or
scope of such immunity were disputed, we would need to institute proceedings to
enforce our rights either under the immunity agreement or under the patent.
 
THE SUCCESS OF OUR BUSINESS WILL DEPEND ON CONTINUED GROWTH OF INTERNET COMMERCE
 
    The market for the purchase of products and services over the Internet is a
new and emerging market. As an Internet commerce business, our future revenues
and profits are substantially dependent upon the widespread acceptance and use
of the Internet and other online services as a medium for commerce by consumers
and sellers. If acceptance and growth of Internet use does not occur, our
business and financial performance will suffer. Rapid growth in the use of and
interest in the Internet and other online services is a recent phenomenon. This
growth may not continue. A sufficiently broad base of consumers may not adopt,
or continue to use, the Internet as a medium of commerce. Demand for and market
acceptance of recently introduced products and services over the Internet are
subject to a high level of uncertainty, and there are few proven products and
services. For us to grow, consumers that historically have purchased through
traditional means of commerce, such as a travel agent for airline tickets or
visiting a branch of a bank for a home mortgage, will need to elect to purchase
online products and services. Sellers of products and services will need to
adopt or expand use of the Internet as a channel of distribution.
 
    The Internet has experienced, and is expected to continue to experience,
significant growth in the number of users and amount of traffic. Our success
will depend upon the development and maintenance of the Internet's
infrastructure to cope with this increased traffic. This will require a reliable
network backbone with the necessary speed, data capacity and security, and the
timely development of complementary products, such as high-speed modems, for
providing reliable Internet access and services.
 
    The Internet has experienced a variety of outages and other delays as a
result of damage to portions of its infrastructure and could face such outages
and delays in the future. Outages and delays are likely to affect the level of
Internet usage and the processing of transactions on the priceline.com Web site.
It is unlikely that the level of orders lost in those circumstances could be
made up by increased phone orders. In addition, the Internet could lose its
viability due to delays in the development or adoption of new standards to
handle increased levels of activity or due to increased government regulation.
The adoption of new standards or government regulation may, however, require us
to incur substantial compliance costs.
 
WE MAY NOT BE ABLE TO KEEP UP WITH THE RAPID TECHNOLOGICAL AND OTHER CHANGES
 
    The markets in which we compete are characterized by rapidly changing
technology, evolving industry standards, frequent new service and product
announcements, introductions and enhancements and changing consumer demands. We
may not be able to keep up with these rapid changes. In addition, these market
characteristics are heightened by the emerging nature of the Internet and the
apparent need of companies from many industries to offer Internet-based products
and services. As a result, our future success will depend on our ability to
adapt to rapidly changing technologies, to adapt our services to evolving
industry standards and to continually improve the performance, features and
reliability of our service in response to competitive service and product
offerings and the evolving demands of the marketplace. In addition, the
widespread adoption of new Internet, networking or telecommunications
technologies or other technological changes could require us to incur
substantial expenditures to modify or adapt our services or infrastructure.
 
                                       14
 
YEAR 2000 RISKS MAY HARM OUR BUSINESS
 
    The risks posed by Year 2000 issues could adversely affect our business in a
number of significant ways. Although we believe that our internally developed
systems and technology are Year 2000 compliant, our information technology
systems nevertheless could be substantially impaired or cease to operate due to
Year 2000 problems. Additionally, we rely on information technology supplied by
third parties, and our participating sellers also are heavily dependent on
information technology systems and on their own third party vendors' systems.
Year 2000 problems experienced by us or any of such third parties could
materially adversely affect our business. Additionally, the Internet could face
serious disruptions arising from the Year 2000 problem.
 
    We are evaluating our internal information technology systems and contacting
our information technology suppliers and participating sellers to ascertain
their Year 2000 status. However, we cannot guarantee that our own systems will
be Year 2000 compliant in a timely manner, that any of our participating sellers
or other Web site vendors will be Year 2000 compliant in a timely manner, or
that there will not be significant interoperability problems among information
technology systems. We also cannot guarantee that consumers will be able to
visit our Web site without serious disruptions arising from the Year 2000
problem. Given the pervasive nature of the Year 2000 problem, we cannot
guarantee that disruptions in other industries and market segments will not
adversely affect our business. Moreover, the costs related to Year 2000
compliance could be significant. Moreover, participating sellers in
priceline.com services might experience substantial slow-downs in business if
consumers avoid products and services such as air travel both before and after
January 1, 2000 arising from concerns about reliability and safety because of
the Year 2000 issue.
 
ONLINE SECURITY BREACHES COULD HARM OUR BUSINESS
 
    The secure transmission of confidential information over the Internet is
essential in maintaining consumer and supplier confidence in the priceline.com
service. Substantial or ongoing security breaches on our system or other
Internet-based systems could significantly harm our business. We currently
require buyers to guarantee their offers with their credit card, either online
or through our toll-free telephone service. We rely on licensed encryption and
authentication technology to effect secure transmission of confidential
information, including credit card numbers. It is possible that advances in
computer capabilities, new discoveries or other developments could result in a
compromise or breach of the technology used by us to protect customer
transaction data.
 
    We incur substantial expense to protect against and remedy security breaches
and their consequences. A party that is able to circumvent our security systems
could steal proprietary information or cause interruptions in our operations.
Security breaches also could damage our reputation and expose us to a risk of
loss or litigation and possible liability. Our insurance policies carry low
coverage limits, which may not be adequate to reimburse us for losses caused by
security breaches. We cannot guarantee that our security measures will prevent
security breaches.
 
    We also face risks associated with security breaches affecting third parties
conducting business over the Internet. Consumers generally are concerned with
security and privacy on the Internet and any publicized security problems could
inhibit the growth of the Internet and, therefore, the priceline.com service as
a means of conducting commercial transactions.
 
OUR STOCK PRICE IS LIKELY TO BE VERY VOLATILE
 
    Prior to this offering, you could not buy or sell our common stock publicly.
Although the initial public offering price was determined based on several
factors, the market price after the offering may vary from the initial offering
price. The market price of our common stock is likely to be highly volatile and
could be subject to wide fluctuations in response to factors such as the
following, some of which are beyond our control:
 
    - quarterly variations in our operating results;
 
                                       15
 
    - operating results that vary from the expectations of securities analysis
      and investors;
 
    - changes in expectations as to our future financial performance, including
      financial estimates by securities analysts and investors;
 
    - changes in market valuations of other Internet or online service
      companies;
 
    - announcements of technological innovations or new services by us or our
      competitors;
 
    - announcements by us or our competitors of significant contracts,
      acquisitions, strategic partnerships, joint ventures or capital
      commitments;
 
    - loss of a major seller participant, such as an airline or hotel chain;
 
    - changes in the status of our intellectual property rights;
 
   
    - loss of a major adaptive marketing partner;
    
 
    - announcements by third parties of significant claims or proceedings
      against us;
 
    - additions or departures of key personnel;
 
    - future sales of our common stock; and
 
    - stock market price and volume fluctuations.
 
    Domestic and international stock markets often experience extreme price and
volume fluctuations. Market fluctuations, as well as general political and
economic conditions, such as a recession or interest rate or currency rate
fluctuations, could adversely affect the market price of our common stock.
 
    The market prices for stocks of Internet-related and technology companies,
particularly following an initial public offering, frequently increase to levels
that bear no relationship to the operating performance of such companies. Such
market prices generally are not sustainable and are subject to wide variations.
If our common stock trades to such levels following this offering, it likely
will thereafter experience a material decline.
 
    In the past, securities class action litigation has often been brought
against a company following periods of volatility in the market price of their
securities. We may in the future be the target of similar litigation. Securities
litigation could result in substantial costs and divert management's attention
and resources.
 
REGULATORY AND LEGAL UNCERTAINTIES COULD HARM OUR BUSINESS
 
    The products and services we offer through the priceline.com service are
regulated by federal and state governments. Our ability to provide such services
is and will continue to be affected by such regulations. The implementation of
unfavorable regulations or unfavorable interpretations of existing regulations
by courts or regulatory bodies, could require us to incur significant compliance
costs, cause the development of the affected markets to become impractical and
otherwise adversely affect our financial performance.
 
    TRAVEL SERVICES
 
   
    We are subject to the laws and regulations of a number of states governing
the offer and/or sale of travel services. For example, Priceline Travel, Inc. is
registered as a "seller of travel" under the California Seller of Travel Act and
is a member of the Airline Reporting Corporation. Priceline.com also will be
making similar filings for registration and membership prior to consummation of
this offering. In addition, a number of state travel laws and regulations
require compliance with specific disclosure, bond and/or other requirements. All
travel registrations were previously held by Priceline Travel. To the extent
that such registrations could be transferred by merger, we succeeded to all such
registrations by merging with Priceline Travel as of March 24, 1999 and we have
obtained other required travel related registrations.
    
 
                                       16
 
    NEW CAR SALES
 
    A number of states have laws and regulations governing the registration and
conduct of automobile dealers and brokers. Such laws generally provide that any
person receiving direct or indirect compensation for selling automobiles or
brokering automobile transactions must register as an automobile broker or
dealer. Registration for automobile dealers/brokers may, among other things,
require the registrant to maintain a physical office in the applicable state, a
dealer lot zoned for automobile sales within the applicable state, and/or a
franchise agreement with the manufacturers of the automobiles to be sold. We
believe that we are not subject to such automobile dealer/broker laws because we
are a car buying service, and not a seller or broker of automobiles, operating
on behalf of customers and participating dealers.
 
    It is uncertain how automobile dealer and broker laws apply to the provision
of automobile selling services offered through the Internet. We have been orally
advised by representatives of a number of states that no enforcement action will
be initiated against Internet companies generally for non-compliance with such
laws until clearer regulatory or legislative guidance is provided.
 
    It is possible, however, that state regulatory bodies could take the view
that we are subject to automobile broker and dealer laws, in which case they
could attempt to require us to register as an automobile broker/dealer in the
applicable states. Given the nature of our business, any requirement to register
under such laws could severely interfere with the conduct of our business.
 
    HOME MORTGAGES
 
    Most states have laws and regulations governing the registration or
licensing and conduct of persons providing mortgage brokerage services. Such
laws and regulations also typically require certain consumer protection
disclosures and compliance with loan solicitation procedures and a variety of
other practices, throughout the various stages of the mortgage solicitation,
application and approval process.
 
    In addition to state law, mortgage brokerage services are heavily regulated
by federal law. For example, the Real Estate Settlement Procedures Act,
prohibits the payment and receipt of mortgage loan referral fees. The act,
however, does permit persons to be compensated for the fair market value of non-
referral services actually rendered.
 
    We introduced our home mortgage service in January 1999. LendingTree serves
as the mortgage broker and provides all mortgage brokerage services. We provide
and are responsible for maintaining the home mortgage service on our Web site
and develop and purchase all advertising. LendingTree will compensate us for the
fair market value of our non-referral services. We believe that offering the
home mortgage service does not require our registration under or compliance with
the mortgage or similar brokerage laws of any jurisdiction. However, it is
possible that one or more regulatory authorities could seek to enforce existing
laws, or otherwise enact new legislation, requiring our registration and
compliance and could scrutinize our compensation arrangement with LendingTree
under the Real Estate Settlement Procedures Act or other federal or state laws.
Such action could severely interfere with the conduct of our business.
 
    LendingTree provides the mortgage brokerage services offered through the
home mortgage service on our Web site and is responsible for maintaining the
necessary and appropriate state registrations and licenses associated with
LendingTree's provision of those mortgage brokerage services. If a state or
federal regulatory authority, or an aggrieved customer, should in the future
claim that LendingTree has failed to comply fully with applicable state or
federal law requirements pertaining to LendingTree's provision of mortgage
brokerage services, our home mortgage service could be materially and adversely
affected and we may be unable to continue to make our home mortgage service
available.
 
    CONSUMER PROTECTION AND RELATED LAWS
 
    All of our services are subject to federal and state consumer protection
laws and regulations prohibiting unfair and deceptive trade practices. We are
also subject to related "plain language" statutes in
 
                                       17
 
place in many jurisdictions, which require the use of simple, easy to read,
terms and conditions in contracts with consumers.
 
    Although there are very few laws and regulations directly applicable to the
protection of consumers in an online environment, it is possible that
legislation will be enacted in this area and could cover such topics as
permissible online content and user privacy, including the collection, use,
retention and transmission of personal information provided by an online user.
Furthermore, the growth and demand for online commerce could result in more
stringent consumer protection laws that impose additional compliance burdens on
online companies. Such consumer protection laws could result in substantial
compliance costs and interfere with the conduct and growth of our business.
 
    BUSINESS QUALIFICATION LAWS
 
    Because our service is available over the Internet in multiple states, and
because we sell to numerous consumers resident in such states, such
jurisdictions may claim that we are required to qualify to do business as a
foreign corporation in each such state. We are qualified to do business in a
limited number of states, and our failure to qualify as a foreign corporation in
a jurisdiction where we are required to do so could subject us to taxes and
penalties for the failure to so qualify and limit our ability to conduct
litigation in such states.
 
    INTERNATIONAL EXPANSION
 
    We intend to explore opportunities for expanding our business into
international markets. It is possible, however, that the priceline.com demand
collection system will not be readily adaptable to the regulatory environments
of certain foreign jurisdictions. In addition, there are various other risks
associated with international expansion. They include language barriers,
unexpected changes in regulatory requirements, trade barriers, problems in
staffing and operating foreign operations, changes in currency exchange rates,
difficulties in enforcing contracts and other legal rights, economic and
political instability and problems in collection.
 
OUR BUSINESS IS SUBJECT TO TAX UNCERTAINTIES
 
    POTENTIAL FEDERAL AIR TRANSPORTATION TAX LIABILITY
 
    Currently, a federal air transportation tax is imposed upon the sale of
airline tickets and generally is collected by the airlines selling the tickets.
The tax is based upon a percentage of the cost of transportation, which was 9%
for periods prior to October 1, 1998 and 8% thereafter. Because of the unique
pricing structures employed in the priceline.com service, such as the amount
paid by the customer for a ticket being different than the amount charged by the
airline for the same ticket with the excess payment, if any, going to us as a
charge for the use of our proprietary business method, it is not clear how this
federal tax should be calculated when sales occur using the priceline.com
service. We have been calculating this tax based on the price charged by the
airline for a ticket, rather than the price paid by the customer. There is a
possibility that current law requires computation of the tax based on the price
paid by the customer to us. Due to the uncertainty of how the federal air
transportation tax applies to sales of airline tickets using the priceline.com
service, we have submitted a written request to the United States Internal
Revenue Service seeking a determination of our federal air transportation tax
obligations. Such determination may not be favorable and may require us to
collect the federal air transportation tax on the total amount paid by consumers
for air travel.
 
    If the determination of the Internal Revenue Service is unfavorable, we
could owe approximately $111,000 in additional taxes as of December 31, 1998. We
have accrued for such potential liability in our combined balance sheet as of
December 31, 1998 and are providing for such potential liability on an ongoing
basis. We have agreed to indemnify and hold harmless certain of our
participating airlines from any liability with respect to such taxes, as well as
to secure the payment of such taxes by a letter of credit.
 
                                       18
 
    STATE TAXES
 
    We file tax returns in such states as required by law based on principles
applicable to traditional businesses. In addition, we do not collect sales or
other similar taxes in respect of transactions conducted through the
priceline.com service (other than the federal air transportation tax referred to
above). However, one or more states could seek to impose additional income tax
obligations or sales tax collection obligations on out-of-state companies, such
as ours, which engage in or facilitate online commerce. A number of proposals
have been made at state and local levels that could impose such taxes on the
sale of products and services through the Internet or the income derived from
such sales. Such proposals, if adopted, could substantially impair the growth of
e-commerce and adversely affect our opportunity to become profitable.
 
    Legislation limiting the ability of the states to impose taxes on
Internet-based transactions recently has been enacted by the United States
Congress. However, this legislation, known as the Internet Tax Freedom Act,
imposes only a three-year moratorium, which commenced October 1, 1998 and ends
on October 21, 2001, on state and local taxes on (1) electronic commerce where
such taxes are discriminatory and (2) Internet access unless such taxes were
generally imposed and actually enforced prior to October 1, 1998. It is possible
that the tax moratorium could fail to be renewed prior to October 21, 2001.
Failure to renew this legislation would allow various states to impose taxes on
Internet-based commerce. The imposition of such taxes could adversely affect our
ability to become profitable.
 
CONCENTRATED CONTROL COULD ADVERSELY AFFECT STOCKHOLDERS
 
   
    Upon consummation of this offering, Mr. Jay S. Walker, the Founder and Vice
Chairman of priceline.com, and Mr. Richard S. Braddock, Chief Executive Officer
of priceline.com, together with their respective affiliates (including, with
respect to Mr. Walker, Walker Digital) will beneficially own approximately 43.1
and 8.0 percent (42.6 and 7.9 percent, respectively, if the underwriters'
over-allotment option is exercised in full), of our outstanding common stock,
subject to certain adjustments. As a result, if Messrs. Walker and Braddock act
together, they will have the ability to control the outcome on all matters
requiring stockholder approval, including the election and removal of directors
and any merger, consolidation or sale of all or substantially all of our assets,
and the ability to control our management and affairs. Such control could
discourage others from initiating potential merger, takeover or other change of
control transactions. As a result, the market price of our common stock could be
adversely affected.
    
 
WE MAY BE UNABLE TO MEET OUR FUTURE CAPITAL REQUIREMENTS
 
    Based on our current operating plan, we anticipate that the net proceeds of
this offering, together with our available funds, will be sufficient to satisfy
our anticipated needs for working capital, capital expenditures and business
expansion for at least the next three years. After that time, we may need
additional capital. Alternatively, we may need to raise additional funds sooner
in order to fund more rapid expansion, to develop new or enhanced services, or
to respond to competitive pressures. If we raise additional funds by issuing
equity or convertible debt securities, the percentage ownership of our
stockholders will be diluted. Furthermore, any new securities could have rights,
preferences and privileges senior to those of the common stock.
 
    We currently do not have any commitments for additional financing. We cannot
be certain that additional financing will be available when and to the extent
required or that, if available, it will be on acceptable terms. If adequate
funds are not available on acceptable terms, we may not be able to fund our
expansion, develop or enhance our products or services or respond to competitive
pressures.
 
SUBSTANTIAL SALES OF OUR COMMON STOCK COULD ADVERSELY AFFECT OUR STOCK PRICE
 
    Sales of a substantial number of shares of common stock after the offering
could adversely affect the market price of the common stock by introducing a
large number of sellers to the market. Given the likely
 
                                       19
 
volatility that will exist for our shares, such sales could cause the market
price of the common stock to decline.
 
   
    After this offering, we will have outstanding 142,320,427 shares of common
stock (143,820,427 shares if the underwriters' over-allotment option is
exercised in full), and we will have reserved an additional 54,056,902 shares of
common stock for issuance pursuant to outstanding stock options and warrants.
All of the shares of common stock to be sold in this offering will be freely
tradable without restriction or further registration under the federal
securities laws unless purchased by our "affiliates," as that term is defined in
Rule 144 under the Securities Act of 1933, as amended. The remaining shares of
outstanding common stock, representing approximately 93% (92% if the
underwriter's over-allotment option is exercised in full) of the outstanding
common stock upon completion of this offering, will be "restricted securities"
under the Securities Act subject to restrictions on the timing, manner and
volume of sales of such shares.
    
 
   
    Our directors, executive officers, key employees and substantially all of
our current stockholders have agreed, subject to certain limited exceptions, for
a period of 180 days after the date of this prospectus, that they will not,
without the prior written consent of Morgan Stanley & Co. Incorporated, directly
or indirectly, offer to sell, sell or otherwise dispose of any shares of common
stock. Subject to the foregoing lock-up agreements, holders of up to 143,983,504
shares of common stock and securities convertible into or exercisable for shares
of common stock will have the right to request the registration of their shares
under the Securities Act. Upon the effectiveness of such registration, all
shares covered by such registration statement will be freely transferable.
Following the consummation of this offering, we also intend to file a
registration statement on Form S-8 under the Securities Act covering 23,875,000
shares of common stock reserved for issuance under the 1997 Omnibus Plan and
9,375,000 shares of common stock reserved for issuance under the 1999 Omnibus
Plan; such registration statement will automatically become effective upon
filing. As of March 26, 1999, options to purchase 10,580,521 shares were vested.
However, none of the options issued or to be issued pursuant to the 1997 Omnibus
Plan or the 1999 Omnibus Plan may be exercised until 180 days after the
offering. Subject to the exercise of such options, shares registered under such
registration statement will be available for sale in the open market immediately
after the 180-day lock-up period expires.
    
 
    We cannot predict if future sales of our common stock, or the availability
of our common stock for sale, will adversely affect the market price for our
common stock or our ability to raise capital by offering equity securities.
 
ANTI-TAKEOVER PROVISIONS AFFECTING US COULD PREVENT OR DELAY A CHANGE OF CONTROL
 
    Provisions of our certificate of incorporation and by-laws and provisions of
applicable Delaware law may discourage, delay or prevent a merger or other
change of control that a stockholder may consider favorable. Our board of
directors has the authority to issue up to 150,000,000 shares of preferred stock
par value $0.01 per share, of priceline.com and to determine the price and the
terms, including preferences and voting rights, of those shares without
stockholder approval. Although we have no current plans to issue additional
shares of our preferred stock, any such issuance could:
 
    - have the effect of delaying, deferring or preventing a change in control
      of our company;
 
    - discourage bids for our common stock at a premium over the market price;
      or
 
    - adversely affect the market price of, and the voting and other rights of
      the holders of, our common stock.
 
    We are subject to certain Delaware laws that could have the effect of
delaying, deterring or preventing a change in control of our company. One of
these laws prohibits us from engaging in a business combination with any
interested stockholder for a period of three years from the date the person
became an interested stockholder, unless certain conditions are met. In
addition, certain provisions of our certificate of incorporation and by-laws,
and the significant amount of common stock held by our executive
 
                                       20
 
officers, directors and affiliates, could together have the effect of
discouraging potential takeover attempts or making it more difficult for
stockholders to change management.
 
OUR MANAGEMENT HAS BROAD DISCRETION OVER USE OF THE PROCEEDS FROM THIS OFFERING
 
   
    The net proceeds of this offering are estimated to be approximately $118.6
million (approximately $136.7 million, if the Underwriters' over-allotment
option is exercised in full) at an assumed initial public offering price of
$13.00 per share and after deducting the estimated underwriting discount and
estimated offering expenses. Our management will retain broad discretion as to
the allocation of the proceeds of this offering.
    
 
YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION
 
   
    The initial public offering price is expected to be substantially higher
than the net tangible book value of each outstanding share of common stock.
Purchasers of common stock in this offering will suffer immediate and
substantial dilution. The dilution will be $11.78 per share in the net tangible
book value of the common stock from the expected initial public offering price.
If outstanding options and warrants to purchase shares of common stock are
exercised, there would be further dilution.
    
 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
    Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business" and elsewhere in this prospectus constitute

                                USE OF PROCEEDS
 
   
    The primary purposes of this offering are to obtain additional capital,
create a public market for the common stock and facilitate future access to
public markets. The net proceeds to priceline.com from the sale of the
10,000,000 shares of common stock offered hereby are estimated to be
approximately $118.6 million (approximately $136.7 million, if the underwriters'
over-allotment option is exercised in full), assuming an initial public offering
price of $13.00 per share and after deducting estimated offering expenses of
$2.3 million and the underwriting discount payable by priceline.com.
Priceline.com intends to use the remainder of the net proceeds, over time, for
general corporate purposes, including working capital to fund anticipated
operating losses, expenses associated with our advertising campaigns, brand-name
promotions and other marketing efforts and capital expenditures. Priceline.com
also could use a portion of the net proceeds, currently intended for general
corporate purposes, to acquire or invest in businesses, technologies, products
or services, although no specific acquisitions are planned and no portion of the
net proceeds has been allocated for any acquisition.
    
 
    As of the date of this prospectus, priceline.com cannot specify with
certainty the particular uses for the net proceeds to be received upon the
consummation of this offering. Accordingly, priceline.com's management will have
broad discretion in the application of the net proceeds. Pending such uses,
priceline.com intends to invest the net proceeds from this offering in
short-term, interest-bearing, investment-grade securities. See "Risk Factors --
We May Be Unable to Meet Our Future Capital Requirements" and "Risk Factors --
Our Management Has Broad Discretion Over Use of the Proceeds of this Offering."
 
                                DIVIDEND POLICY
 
    Priceline.com has not declared or paid any cash dividends on its capital
stock since its inception and does not expect to pay any cash dividends in the
foreseeable future. Priceline.com currently intends to retain future earnings,
if any, to finance the expansion of its business.
 
                                       22
 
                                 CAPITALIZATION
 
   
    Unless otherwise indicated, all information in this prospectus (1) reflects
a 1.25 for one stock split of our common stock and the conversion of all
outstanding shares of our convertible preferred stock into 38,907,728 shares of
common stock upon the consummation of this offering and (2) assumes that the
underwriters' over-allotment option will not be exercised. See "Description of
Capital Stock" and "Underwriters."
    
 
   
    The following table sets forth the capitalization of priceline.com as of
December 31, 1998: (1) on an actual basis and (2) on a pro forma basis to
reflect the consummation of the merger between priceline.com and Priceline
Travel, Inc. on March 24, 1999, as adjusted to reflect (a) the conversion of all
outstanding shares of convertible preferred stock into common stock upon the
consummation of this offering and (b) the receipt by priceline.com of the
estimated net proceeds from the sale of the 10,000,000 shares of common stock
offered hereby at an assumed initial public offering price of $13.00 per share
(after deducting the estimated offering expenses and underwriting discount).
This table should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the combined
financial statements and related notes thereto included elsewhere in this
prospectus.

(a)  Excludes (1) 23,800,875 shares of common stock issuable on exercise of
    options outstanding as of March 26, 1999, with a weighted average exercise

                                    DILUTION
 
   
    The pro forma net tangible book value of priceline.com as of December 31,
1998 was $55.3 million, or $0.42 per share. Pro forma net tangible book value
per share is determined by dividing the pro forma number of outstanding shares
of common stock, after giving effect to the conversion of all outstanding shares
of our convertible preferred stock into 38,907,728 shares of common stock, into
the net tangible book value of priceline.com (total tangible assets less total
liabilities). Assuming the sale by priceline.com of the 10,000,000 shares of
common stock offered hereby at an assumed initial public offering price of
$13.00 per share and after deducting the estimated underwriting discount and
estimated offering expenses, the pro forma net tangible book value of
priceline.com as of December 31, 1998 would have been approximately $173.8
million, or $1.22 per share. This represents an immediate increase in pro forma
net tangible book value of $0.80 per share to existing stockholders and an
immediate dilution of $11.78 per share to new investors purchasing shares at the
initial public offering price. The following table illustrates the per share
dilution:
    
 
   

 Assumed initial public offering price per share............. $ 13.00 Pro forma net tangible book value per share as of December 31, 1998....................................... $ 0.42 Increase in pro forma net tangible book value per share attributable to new investors........................... 0.80 --------- Pro forma net tangible book value per share after the offering.................................................. 1.22 --------- Dilution per share to new investors......................... $ 11.78 --------- ---------

 
    
 
   
    The following table summarizes as of December 31, 1998, on the pro forma
basis described above, the number of shares of capital stock purchased from
priceline.com, the total consideration paid to priceline.com and the average
price per share paid by existing stockholders and by investors purchasing shares
of common stock in this offering at an assumed initial public offering price of
$13.00 (before deducting the estimated underwriting discount and estimated
offering expenses):

    and will increase the number of shares of common stock held by new investors
    to 11,500,000 shares or 8.0% of the total number of shares of common stock
    to be outstanding upon consummation of this offering. See "Principal
    Stockholders."
 
   
    The foregoing discussion and tables exclude (1) 23,800,875 shares of common

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL EVENTS OR RESULTS MAY DIFFER MATERIALLY FROM THOSE
INDICATED IN SUCH FORWARD-LOOKING STATEMENTS. SEE "SPECIAL NOTE REGARDING
FORWARD-LOOKING STATEMENTS." THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION
AND RESULTS OF OPERATIONS OF PRICELINE.COM ALSO SHOULD BE READ IN CONJUNCTION
WITH THE COMBINED FINANCIAL STATEMENTS AND RELATED NOTES THERETO INCLUDED
ELSEWHERE IN THIS PROSPECTUS.
 
OVERVIEW
 
    Priceline.com has pioneered a unique new type of e-commerce known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price," priceline.com collects consumer demand, in the
form of individual customer offers guaranteed by a credit card, for a particular
product or service at a price set by the customer. Priceline.com then either
communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether it can fulfill the
customer's offer on the basis of the pricing information and rules established
by the sellers. Consumers agree to hold their offers open for a specified period
of time and, once fulfilled, offers cannot be canceled. Priceline.com benefits
consumers by enabling them to save money, while at the same time benefitting
sellers by providing them with an effective revenue management tool capable of
identifying and capturing incremental revenues. By requiring consumers to be
flexible with respect to brands, sellers and product features, priceline.com
enables sellers to generate incremental revenue without disrupting their
existing distribution channels or retail pricing structures.
 
   
    Priceline.com was formed in July 1997 and its primary activities during the
period prior to launch consisted of recruiting and training employees,
developing its business model, implementing systems to support its business
model, developing relationships with seller participants and developing the
priceline.com brand. Priceline.com commenced operations in April 1998 with the
sale of leisure airline tickets. Priceline.com's services were expanded to
include the sale of new automobiles, on a test basis, in July 1998, hotel room
reservations in October 1998 and home mortgages through a third party mortgage
service in January 1999. The number of employees of priceline.com increased from
10 to 123 during the period from inception through the year ended December 31,
1998, and as of March 26, 1999 priceline.com had 194 employees.
    
 
    Priceline.com earns revenues upon the completion of successful transactions
through the priceline.com service, which in certain cases includes revenues
generated through adaptive marketing programs offered through the priceline.com
service. The manner in which priceline.com earns revenues varies, however,
depending on the product or service sold. With respect to airline and hotel
reservation services, priceline.com earns the spread between the customer's
named price and the fare or rate charged by the seller. With respect to the
automobile service, it earns a fixed fee from both the customer and the seller
after the transaction is consummated. With respect to the home mortgage service,
it receives a payment equal to a percentage of the net revenue generated from
the mortgage program, which is operated in conjunction with LendingTree, Inc.
Priceline.com also generates revenues through adaptive marketing programs with
third parties that pay priceline.com fees for marketing their customer
acquisition programs. Revenues from adaptive marketing promotions currently
consist primarily of fees paid by a third-party credit card issuer for
qualifying credit card applications submitted through the priceline.com service
in connection with offers for airline tickets. Consumer fees are payable only
upon completion of successful transactions.
 
    All offers made through the priceline.com service are guaranteed by a
customer credit card and credit cards are the only form of payment accepted by
priceline.com. The manner in which and time at which
 
                                       26
 
revenues are recognized differs depending on the product or service sold through
the priceline.com service. With respect to airline ticket and hotel reservation
services, revenues are generated by transactions with customers who make offers
to purchase airline tickets and reserve hotel rooms supplied by participating
sellers. Revenues and related costs are recognized if, and when, priceline.com
accepts the customer's offer and charges the customer's credit card. Because
priceline.com is the merchant of record in these transactions, revenue for these
services includes the amount billed to the customer, net of certain
transportation taxes and fees. Airline and hotel revenues also may include fees
from third parties for adaptive marketing programs. With respect to automobile
and mortgage services, fees or other payments payable by the seller and/or the
customer are recognized as revenue. Because priceline.com acts as an
intermediary between the customer and the seller in these transactions, revenues
for these products and services is recorded at the amount of the fee received in
connection with the transaction, and not on the value of the underlying
transaction, when the transaction is completed. Automobile and mortgage services
revenues also may include fees from third parties for adaptive marketing
programs.
 
    Priceline.com believes that its offer fulfillment rate for airline tickets
was constrained during 1998 by the availability of airline ticket inventory,
which initially was limited by the inclusion of only Trans World Airlines and
America West Airlines as participating domestic carriers. With the addition of
Delta Air Lines on a part time basis in September 1998 and on a full time basis
in November 1998, and the addition of Northwest Airlines in October 1998,
priceline.com has expanded its potential inventory breadth to cover more
domestic markets and has increased the depth of potential inventory in markets
that priceline.com serves. Priceline.com believes that it can increase the
amount of ticket sales and improve its offer fulfillment rate as its business
matures by (1) expanding the depth and breadth of airline ticket inventory, (2)
demonstrating to airlines how they can utilize revenue management strategies to
fulfill a larger share of reasonable offers, and (3) expanding adaptive
marketing programs to help increase the number of completed transactions.
 
   
    During the period from launch through December 31, 1998, priceline.com
collected guaranteed offers for approximately 1.9 million airline tickets,
representing approximately $400.0 million in total consumer demand. This demand
resulted in sales of approximately 134,900 airline tickets, representing
approximately $30.4 million in revenue. During the two month period from January
1, 1999 through February 28, 1999, priceline.com collected guaranteed offers for
approximately 830,300 airline tickets, representing approximately $170.0 million
in total consumer demand. This demand resulted in sales of approximately 102,700
airline tickets, representing approximately $21.1 million in revenue.
    
 
    Because the priceline.com system does not set minimum offer thresholds, and
consumers are not charged to make offers for airline tickets and other products,
it is expected that priceline.com will receive a significant number of
unreasonable or fantasy offers. Accordingly, priceline.com also analyzes the
percentage of "reasonable" ticket requests that it is able to fill.
Priceline.com considers an offer for an airline ticket to be "reasonable" when
it is no more than 30% lower than the lowest generally available advance-
purchase fare for the same route. Using this standard, the overall percentage of
ticket requests considered reasonable for the two-month period ended February
28, 1999 was approximately 53%. The 102,700 tickets sold through priceline.com
during the two-month period represented approximately 24% of the combined
reasonable ticket requests for domestic and international flights. For domestic
routes where priceline.com's airline participants have strong coverage, that
percentage was higher, with approximately 26% of all reasonable requests
fulfilled for the same two-month period. The percentage of reasonable offers
that priceline.com is able to fill can also vary depending on the particular
route. For example, priceline.com was able to fill approximately 73% of
reasonable offers for tickets from New York to San Francisco, and 73% of
reasonable offers for tickets from Los Angeles to London for the two-month
period ended February 28, 1999.
 
    Since its inception, priceline.com has incurred net losses in each fiscal
quarter. Priceline.com incurred net losses of $49.0 million during the period
from July 18, 1997 (inception) through December 31, 1998, before giving effect
to $67.9 million of non-cash charges arising from equity issuances to a number
of our
 
                                       27
 
participating airlines, our chief executive officer and other parties, as more
fully described below. As of December 31, 1998, priceline.com had an accumulated
deficit of $116.9 million. Priceline.com believes that its continued growth will
depend in large part on its ability to continue to promote the priceline.com
brand and to apply the priceline.com business model to a wide range of products
and services. Accordingly, priceline.com intends to continue to invest heavily
in marketing and promotion, technology and personnel. As a result, it expects to
incur additional losses for the foreseeable future. See "Risk Factors -- We Are
Not Profitable and Expect to Continue to Incur Losses." In addition,
priceline.com's limited operating history makes the prediction of future results
of operations difficult, and accordingly, there can be no assurance that it will
achieve or sustain revenue growth or profitability. See "Risk Factors --
Potential Fluctuations in Our Financial Results Makes Financial Forecasting
Difficult."
 
   
    For the year ended December 31, 1998, priceline.com recorded aggregate
non-cash charges of $67.9 million. Of this amount, $6.5 million related to the
issuance of 8,125,000 shares of common stock to Mr. Richard S. Braddock, the
Chairman and Chief Executive Officer of priceline.com, and $61.1 million related
to the issuance of warrants to purchase 19,744,402 shares of common stock,
including warrants to purchase 19,556,902 shares of common stock issued to a
number of our participating airlines. Priceline.com intends to hire a new chief
operating officer. See "Management -- New Chief Operating Officer." The
compensation committee of the board of directors has reserved options to
purchase up to 2,000,000 shares of common stock for grant to one or more senior
officers, including a new chief operating officer, with an exercise price equal
to the initial public offering price. If such options are granted after
consummation of this offering, priceline.com will recognize compensation expense
to the extent the fair value of the underlying stock exceeds the exercise price
over the vesting period of the options. We expect the majority of such options
to be granted in the year ended December 31, 1999.
    
 
   
    In August 1998, priceline.com entered into a warrant agreement with Delta to
purchase up to 18,892,603 shares of common stock at an exercise price of
approximately $0.93 per share. Vesting was contingent upon achievement of
certain predetermined performance thresholds. However, there was no penalty for
failure to provide ticket inventory to satisfy these performance thresholds.
Accordingly, no expense was recorded when the warrant was issued. On December
31, 1998, priceline.com amended its agreement with Delta to eliminate the
vesting contingencies and fix the number of shares subject to the warrant at
18,619,402. The amended warrant issued to Delta will become exercisable at the
earlier of seven years or upon the achievement of certain performance
thresholds. However, the agreement does not require Delta to make any
performance commitments, is non-exclusive and allows Delta to participate in
other programs similar to the priceline.com service. Included in the non-cash
charges described above is approximately $58.7 million reflecting the fair value
of the Delta warrant on December 31, 1998.
    
 
   
    Priceline.com's travel agency license was previously held by Priceline
Travel, a separate company that was owned by Mr. Jay S. Walker, priceline.com's
Founder and Vice Chairman, and all of its airline ticket sales were effected
through Priceline Travel, which was merged with and into priceline.com as of
March 24, 1999. Accordingly, the financial statements of Priceline Travel are
presented on a combined basis with priceline.com.
    
 
RESULTS OF OPERATIONS
 
YEAR ENDED DECEMBER 31, 1998
 
    Priceline.com was formed in July 1997, but did not commence operations until
April 1998. Because of priceline.com's limited operating history, comparisons
with prior periods are not meaningful.
 
RESTATEMENT
 
    Subsequent to the issuance of priceline.com's combined 1998 financial
statements, priceline.com's management determined that the calculation of the
fair value of the Delta warrant, other airline warrants and the beneficial
conversion feature on the series B preferred stock should be revised. The fair
value of
 
                                       28
 
   
the Delta warrant and the other airline warrants has been revised to reflect the
change in the volatility assumption from 50% to 132%, eliminate the "large
block" and lack of marketability discounts, and consider the warrant's
anti-dilution and exercisability features. As a result, the 1998 combined
financial statements have been restated from the amounts previously reported to
recognize an additional $22.0 million of expense based upon the revised fair
value of the warrants at December 31, 1998, of which $3.0 million is included in
the cost of revenues-supplier warrant costs and $19.0 million is included in
expenses-supplier start-up warrant costs. In addition, the value of the
beneficial conversion feature on the series B preferred stock has been revised
to calculate such amount based on 22,500,000 shares. As a result, additional
paid-in capital and accumulated deficit have been restated from amounts
previously reported to recognize an additional $883,424 of accretion of
preferred stock based on the revalued beneficial conversion feature.
    
 
    A summary of the significant effects of the restatement is as follows:
 

AS PREVIOUSLY REPORTED AS RESTATED -------------- --------------- At December 31, 1998: Additional paid-in capital................................ $ 148,224,070 $ 171,155,186 Accumulated deficit.......................................

- ------------------------
 
(1) Basic and diluted loss per common share as previously reported has been
    restated for a 1.25 for one stock split.
 
    REVENUES
 
    Total revenues for the year ended December 31, 1998 were $35.2 million.
Since commencement of operations in April 1998, essentially all revenues
consisted of airline ticket sales, hotel room reservations and related adaptive
marketing programs. Approximately $4.0 million of total revenues were
attributable to adaptive marketing programs, all of which were attributable to
priceline.com's third-party credit card marketing program with Capital One Bank.
See "-- Cost of Revenues and Gross Profit (Loss)." Priceline.com's automobile
sales service, which was launched on a test basis in the New York metropolitan
area in July 1998, did not contribute materially to revenues during the period.
 
    COST OF REVENUES AND GROSS PROFIT (LOSS)
 
    Cost of revenues for the year ended December 31, 1998 totaled $36.5 million,
consisting of product costs of $33.5 million and supplier warrant costs of $3.0
million. Product costs represent the cost of airline tickets from
priceline.com's suppliers, net of the federal air transportation tax, segment
fees and passenger facility charges imposed in connection with the sale of
airline tickets. Supplier warrant costs represent a non-cash expense related to
the pro-rata amount of the Delta warrant earned prior to December 31, 1998, the
date on which the Delta warrant was amended. Priceline.com anticipates that it
will recognize additional supplier warrant costs in the amount of $1.6 million
in each of 1999 and 2000 in connection with additional warrants issued to a
participating airline in January 1999.
 
    Gross profit (loss), which is comprised of revenues less cost of revenues,
was $(1.3) million for the year ended December 31, 1998. Excluding the effect of
the non-cash supplier warrant costs, priceline.com
 
                                       29
 
would have had gross profit of $1.7 million for the year ended December 31,
1998. Priceline.com is able to manage the level of gross margins by controlling
the price at which it will cause offers to be fulfilled. Priceline.com has
chosen to sell a substantial number of tickets below its cost in order to
increase airline and adaptive marketing revenues, build a record of successful
transactions, and enhance the priceline.com brand. Because the fees generated by
adaptive marketing programs had no separate costs, adaptive marketing revenues
had a disproportionately positive impact on priceline.com's total gross margin.
The Capital One adaptive marketing program accounted for all of priceline.com's
adaptive marketing revenues in 1998. Priceline.com expects that, in the future,
a substantial portion of its gross profit may be attributable to adaptive
marketing programs. As priceline.com matures, it expects to reduce the
percentage of airline tickets sold below cost and continue to improve total
gross margins.
 
    The Capital One adaptive marketing program accounted for all of
priceline.com's adaptive marketing revenues in 1998. On March 3, 1999, Capital
One exercised its contractual option to cease accepting credit card applications
through priceline.com effective May 1, 1999 unless priceline.com enters into a
new agreement with Capital One on revised terms that Capital One has offered
priceline.com. Priceline.com has entered into an agreement in principle with
First USA Bank to establish a credit card adaptive marketing program that would
replace the existing Capital One program. See "Risk Factors -- We are Dependent
on Adaptive Marketing Programs." Capital One currently pays a fee for each
qualifying credit card application submitted over the priceline.com service. The
fee structure of the First USA program is based on different factors and may or
may not result in revenues comparable to those under the Capital One program. If
priceline.com fails to secure a new adaptive marketing program with First USA or
another credit card issuer, its revenues and gross margin are likely to decrease
significantly, which could materially and adversely affect its business and
prospects.
 
    OPERATING EXPENSES
 
    SUPPLIER START-UP WARRANT COSTS.  Supplier start up warrant costs for the
year ended December 31, 1998 totaled $58.0 million, or 164.5% of revenues.
Supplier start up warrant costs consist of a non-cash charge representing the
fair value of warrants issued to certain of our participating airlines in
connection with securing the Company's relationship with those airlines.
 
    SALES AND MARKETING.  Sales and marketing expenses for the year ended
December 31, 1998 totaled $24.4 million, or 69.2% of revenues. Approximately 50%
of sales and marketing expenses were comprised of radio and newspaper
advertising expenses. The balance was comprised of (1) fees payable to a third
party service provider, which operates priceline.com's call center, (2) credit
card processing fees, (3) provisions for customer credit card charge-backs
(based upon a percentage reflecting priceline.com's historical experience), and
(4) compensation for priceline.com's sales and marketing personnel.
 
    SYSTEMS AND BUSINESS DEVELOPMENT.  Systems and business development expenses
for the year ended December 31, 1998 totaled $11.1 million, or 31.6% of
revenues. Systems and business development expenses are comprised primarily of
compensation to priceline.com's information technology and product development
staff and payments to outside contractors, data communications and other
expenses associated with operating priceline.com's Web site and, to a lesser
extent, depreciation on computer hardware and licensing fees for computer
software.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses for the
year ended December 31, 1998 totaled $18.0 million or 51.1% of revenues. General
and administrative expenses consist primarily of compensation for personnel,
fees for outside professionals, telecommunications and other overhead costs,
including occupancy expense. Also included is a one-time non-cash charge of $6.5
million relating to the issuance to Mr. Richard S. Braddock of a profits
interest with respect to 6.5 million units in priceline.com's predecessor,
priceline.com LLC. These units were granted to Mr. Braddock in connection with
his employment by priceline.com, and were subsequently converted into 8,125,000
shares of common stock.
 
                                       30
 
    INTEREST INCOME (EXPENSE), NET
 
    Interest income (expense), net for the year ended December 31, 1998 totaled
$548,374, reflecting approximately $633,000 of interest income earned by
priceline.com on its cash balances, net of interest expense for the period.
 
PERIOD ENDED DECEMBER 31, 1997
 
    During the period from its formation in July 1997 through December 31, 1997,
priceline.com was engaged in start-up activities and incurred $2.5 million of
operating expenses. These operating expenses primarily consisted of investments
in technology and personnel related expenses. No revenues were earned during the
period. As of December 31, 1997, priceline.com had a cumulative net loss of $2.5
million.
 
QUARTERLY RESULTS OF OPERATIONS
 
    The following table sets forth, for the periods presented, data regarding
priceline.com's revenues, cost of revenues and gross profit (loss). Such data
has been derived from priceline.com's unaudited combined financial statements
which, in the opinion of priceline.com's management, have been prepared on
substantially the same basis as the audited combined financial statements,
subject to normal year end adjustments. The operating results in any quarter are
not necessarily indicative of the results that may be expected for any future
period.
 

QUARTER ENDED --------------------------------------------------------- MARCH 31, JUNE 30, SEPTEMBER 30, DECEMBER 31, 1998 1998 1998 1998 ------------- ------------ ------------- ------------- Revenues............................. -- $ 7,030,913 $ 9,212,820 $ 18,993,127 Cost of revenues: Product costs...................... -- 7,951,584 8,842,313 16,701,848 Supplier warrant costs............. -- -0- -0- 3,029,014 --- ------------ ------------- ------------- Total cost of revenues............. -- 7,951,584 8,842,313 19,730,862 --- ------------ ------------- ------------- Gross profit (loss).................. -- (920,671) 370,507 (737,735) Gross margin......................... -- (13.1)% 4.0% (3.9)%

 

 

 
 
    Revenues increased in each quarter since the commencement of operations in
April 1998. The increase in each quarter is due primarily to an increase in
airline ticket sales resulting from expanded inventory, improved fill rates and
an expanded customer base due to increased market awareness and acceptance of
the priceline.com service. In addition to the foregoing, the increase in revenue
in the fourth quarter of 1998 is due to the addition of a significant new
airline partner and the inclusion for a full quarter of priceline.com's
principal adaptive marketing program, as well as, to a lesser extent, the
introduction of priceline.com's hotel reservation service in October 1998.
 
    Cost of revenues, which consist of product costs and supplier warrant costs,
increased each quarter of 1998. Product costs, which are primarily associated
with the amounts paid to priceline.com's airline partners for airline tickets,
net of federal air transportation tax, segment fees and passenger facility
charges imposed in connection with the sale of airline tickets, also increased
each quarter of 1998 in conjunction with increases in total revenue. Supplier
warrant costs consist of a non-cash expense related to the pro-rata amount of
the Delta warrant earned prior to December 31, 1998, the date on which the Delta
Warrant agreement was amended. Excluding the effect of the non-cash supplier
warrant costs, priceline.com's gross profit would have increased every quarter
from $(920,671) for the quarter ended June 30, 1998 to $370,507 for the quarter
ended September 30, 1998 and to $2.3 million for the quarter ended December 31,
1998. Excluding the effect of the non-cash supplier warrant costs,
priceline.com's gross margin would have increased from (13.1)% during the
quarter ended June 30, 1998 to 4.0% for the quarter ended September 30, 1998 and
to 12.1% during the quarter ended December 31, 1998. The increase in gross
margins
 
                                       31
 
(excluding the effect of non-cash supplier warrant costs) during the fourth
quarter resulted primarily from the contribution of adaptive marketing revenues
which have no separate costs and, consequently, have a disproportionate impact
on total gross margins. The Capital One adaptive marketing program, which
accounted for substantially all of priceline.com's adaptive marketing revenues,
was initiated in August 1998. While the Capital One program will cease to be
effective May 1, 1999, priceline.com has entered into an agreement in principle
with First USA Bank to replace Capital One in its adaptive marketing program.
See "Risk Factors -- We are Dependent on Adaptive Marketing Programs."
 
    Priceline.com's quarterly operating results will be affected by a variety of
factors, many of which are outside its control. Factors that may affect
priceline.com's quarterly operating results include:
 
    - its ability to increase both consumers' and sellers' use of the
      priceline.com service;
 
    - its ability to attract new sellers of products and services to participate
      in the priceline.com service;
 
    - its ability to expand the products and services offered;
 
    - its ability to increase gross margins on products and services sold while
      still increasing sales;
 
    - its ability to successfully implement the First USA adaptive marketing
      program;
 
    - the fulfillment rate of customers' offers;
 
    - the results of its adaptive marketing programs;
 
    - the announcement or introduction of new sites, services and products by
      its competitors;
 
    - the success of its brand building and marketing campaigns;
 
    - price competition in the sale of products and services offered over the
      priceline.com system;
 
    - its ability to upgrade and develop its systems and infrastructure to
      accommodate growth;
 
    - its ability to attract new personnel in a timely and effective manner;
 
    - the occurrence of technical difficulties or service interruptions;
 
    - the amount and timing of operating costs and capital expenditures relating
      to expansion of its business, operations and infrastructure;
 
    - changes in governmental regulation by federal or local governments; and
 
    - general economic conditions and economic conditions specific to the
      Internet and online commerce industries, as well as the individual
      industries, for the products and services sold through the priceline.com
      system.
 
    As a result of priceline.com's limited operating history and the emerging
nature of the market for online commerce, it is difficult for priceline.com to
forecast its revenues or earnings accurately. In addition, priceline.com has no
backlog, with virtually all of its revenues for a particular quarter being
derived from offers that are made and accepted during that quarter.
Priceline.com's current and future expense levels are based largely on its
investment plans and estimates of future revenues and are, to a large extent,
fixed. Priceline.com may be unable to adjust spending in a timely manner to
compensate for any unexpected revenue shortfall. Accordingly, any significant
shortfall in revenues relative to priceline.com's planned expenditures would
have an immediate adverse effect on its business, results of operations and
financial condition.
 
    Priceline.com's limited operating history and rapid growth makes it
difficult for it to assess the impact of seasonal factors on its business.
Nevertheless, priceline.com expects its business to be subject to seasonal
fluctuations, reflecting a combination of seasonality trends for the products
and services offered by the
 
                                       32
 
priceline.com service and seasonality patterns affecting Internet use. For
example, with regard to priceline.com's travel products, demand for leisure
travel may increase over summer vacations and holiday periods, while Internet
usage may decline during the summer months. Priceline.com's results also may be
affected by seasonal fluctuations in the inventory made available to the
priceline.com service by participating sellers. Airlines, for example, typically
enjoy high demand for tickets through traditional distribution channels for
travel during Thanksgiving and the year-end holiday period. As a result, during
those periods, airlines may have less excess inventory to offer through
priceline.com at discounted prices. Priceline.com's business also may be subject
to cyclical variations for the products and services offered; for example,
leisure travel and home mortgage financing tends to decrease in economic
downturns.
 
    Due to the foregoing factors, priceline.com's quarterly revenues and
operating results are difficult to forecast. Priceline.com believes that
period-to-period comparisons of its operating results may not be meaningful and
should not be relied upon as an indication of future performance. In addition,
it is possible that in one or more future quarters priceline.com's operating
results will fall below the expectations of securities analysts and investors.
In such event, the trading price of the common stock would almost certainly be
materially adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Since its inception, priceline.com has financed its operations primarily
through the sale of equity securities. Net proceeds from financing activities
since inception through December 31, 1998 totaled approximately $103.2 million.
Priceline.com's initial equity capital of approximately $27.0 million was
provided by Mr. Jay S. Walker, other high net worth individuals and a
partnership affiliated with General Atlantic Partners, LLC, a private equity
firm that invests worldwide in software and information technology companies. An
additional $20.0 million was invested by two partnerships affiliated with
General Atlantic in July 1998. On December 8, 1998, priceline.com received
approximately $54.4 million in proceeds from the sale of equity securities in a
private offering to a group of corporate and institutional investors and high
net worth individuals, including two partnerships affiliated with General
Atlantic; Vulcan Ventures, Incorporated; Liberty PL, Inc.; a wholly owned
subsidiary of Liberty Media Corporation; Quantum Industrial Partners LDC, a fund
managed by Soros Fund Management, LLC and Allen & Company, Incorporated. Allen &
Company, Incorporated also has served as priceline.com's financial advisor. At
December 31, 1998, priceline.com's principal source of liquidity was
approximately $53.6 million in cash and cash equivalents.
 
    In April 1998, priceline.com received proceeds from a loan of $1.0 million
for working capital from a high net worth individual who also was issued a
warrant to purchase 62,500 shares of common stock at an exercise price of $0.80
per share. This loan expires on April 15, 2003 and bears interest at a rate of
6.0%. The related warrant has been fully exercised.
 
    Prior to completion of this offering, priceline.com intends to make a loan
to Mr. Richard S. Braddock in an amount sufficient to enable the payment of
taxes related to the issuance to Mr. Braddock of 8,125,000 shares of common
stock. The loan will bear interest at the applicable federal rate specified from
time to time by the Internal Revenue Service. Principal and interest on the loan
will be payable in January 2004.
 
    Net cash used in operating activities was $40.9 million for the year ended
December 31, 1998. Net cash used in operating activities was primarily
attributable to net losses.
 
    Net cash used in investing activities was $6.6 million for the year ended
December 31, 1998. Net cash used in investing activities was primarily related
to purchases of property and equipment.
 
    Net cash provided by financing activities was $101.1 million for the year
ended December 31, 1998. Net cash provided by financing activities resulted
primarily from the issuance of equity securities referred to above.
 
                                       33
 
    Priceline.com had no material commitments for capital expenditures at
December 31, 1998 but expects such expenditures to be at least $10.0 million in
1999. Such expenditures will be primarily for computer equipment, leasehold
improvements related to newly leased space and other property and equipment.
Priceline.com believes that, based upon its current operating plan, its existing
cash and cash equivalents, the net proceeds from this offering and any cash
generated from operations will be sufficient to fund its operating activities,
capital expenditures and other obligations through at least the next three
years. However, if during that period or thereafter priceline.com is not
successful in generating sufficient cash flow from operations or in raising
additional capital when required in sufficient amounts and on terms acceptable
to priceline.com, these failures could have a material adverse effect on
priceline.com's business, results of operations and financial condition. If
additional funds are raised through the issuance of equity securities, the
percentage ownership of its then-current stockholders would be diluted.
 
MARKET-RELATED RISKS
 
    Priceline.com currently has no floating rate indebtedness, holds no
derivative instruments and does not earn significant foreign-sourced income.
Accordingly, changes in interest rates or currency exchange rates do not
generally have a direct effect on priceline.com's financial position. However,
changes in currency exchange rates may affect the cost of international airline
tickets and international hotel reservations offered through the priceline.com
service, and so indirectly affect consumer demand for such products and
priceline.com's revenue. In addition, to the extent that changes in interest
rates and currency exchange rates affect general economic conditions,
priceline.com would also be affected by such changes.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1998, Statement of Financial Accounting Standards No. 133
"Accounting for Derivative Instruments and Hedging Activities" was released. The
statement requires the recognition of all derivatives as either assets or
liabilities in the balance sheet and the measurement of those instruments at
fair value. The accounting for changes in the fair value of a derivative depends
on the planned use of the derivative and the resulting designation.
Priceline.com is required to implement the statement in the first quarter of
fiscal 2000. Priceline.com has not used derivative instruments and believes the
impact of adoption of this statement will not have significant effect on its
financial statements.
 
    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, Accounting for Costs of Computer Software developed
or obtained for internal use. This statement is effective for fiscal years
beginning after December 15, 1998. This statement provides guidance on
accounting for the cost of computer software developed or obtained for internal
use. Priceline.com adopted this statement on January 1, 1999 and currently is in
the process of evaluating its impact.
 
TAX MATTERS
 
NET OPERATING LOSS CARRYFORWARDS
 
    Through July 31, 1998, priceline.com operated as a limited liability
company, and income taxes (benefits) accrued to its members. During the year
ended December 31, 1998, priceline.com had a net loss, and since converting from
a limited liability company to a corporation in July 1998, it has incurred a tax
net operating loss of $9.3 million. Priceline.com's initial corporate tax return
will be for the period August 1 through December 31, 1998. Priceline.com has
provided a full valuation allowance on the deferred tax asset of $38.0 million
because of the uncertainty regarding its realization. Priceline.com's accounting
for deferred taxes under Statement of Financial Accounting Standards No. 109
involves the evaluation of a number of factors concerning the realizability of
its deferred tax assets. In concluding that a full valuation allowance was
required, management primarily considered such factors as priceline.com's
history of losses from operations and expected future losses. See Notes 2 and 8
of Notes to Combined Financial Statements included elsewhere in this prospectus.
 
                                       34
 
FEDERAL AIR TRANSPORTATION TAX ON AIRLINE TICKET SALES
 
    Currently, a federal air transportation tax is imposed upon the sale of
airline tickets and generally is collected by the airlines selling the tickets.
The tax is based upon a percentage of the cost of transportation, which was 9%
for periods prior to October 1, 1998 and 8% thereafter. Because of the unique
pricing structures employed in the priceline.com service, such as the amount
paid by the customer for a ticket being different than the amount charged by the
airline for the same ticket with the excess payment, if any, going to
priceline.com as a charge for the use of its proprietary business method, it is
not clear how this federal tax should be calculated when sales occur using the
priceline.com service. Priceline.com has been calculating this tax based on the
fare paid to the airline for a ticket, rather than the price paid by the
customer. There is a possibility that current law requires computation of the
tax based on the price paid by the customer to priceline.com. Due to the
uncertainty of how the federal air transportation tax applies to sales of
airline tickets using the priceline.com service, priceline.com has submitted a
written request to the United States Internal Revenue Service seeking a
determination of priceline.com's federal air transportation tax obligations.
Such determination may not be favorable and may require priceline.com to collect
federal air transportation tax on the total amount paid by consumers for air
travel.
 
   
    If the determination of the Internal Revenue Service is unfavorable,
priceline.com could owe $111,000 in additional taxes as of December 31, 1998.
Priceline.com has accrued for such potential liability in its combined balance
sheet as of December 31, 1998 and is providing for such potential liability on
an ongoing basis. Priceline.com has agreed to indemnify and hold harmless
certain of our participating airlines from any liability with respect to such
taxes as well as to secure the payment of such taxes by a letter of credit.
    
 
NON-QUALIFIED STOCK OPTIONS
 
   
    Priceline.com currently has outstanding non-qualified stock options to
purchase 23,800,875 shares issued to various employees, consultants and
directors pursuant to the 1997 Omnibus Plan. Each option entitles its holder to
purchase a share of common stock at a weighted average exercise price of
approximately $1.25 per share, subject to adjustment in accordance with the 1997
Omnibus Plan. On exercise of an option, priceline.com will be entitled to an
income tax deduction equal to the difference between the exercise price of the
option and the then fair market value of the common stock. As the exercise of
options is in the sole discretion of the holder of the options, the timing of
the corresponding income tax deduction is outside the control of priceline.com.
    
 
YEAR 2000 READINESS DISCLOSURE
 
PRICELINE.COM'S STATE OF READINESS
 
    Priceline.com has defined Year 2000 compliance as follows:
 
    Information technology time and date data processes, including, but not
limited to, calculating, comparing and sequencing data from, into and between
the 20th and 21st centuries contained in our products and services offered
through the priceline.com service, will function accurately, continuously and
without degradation in performance and without requiring intervention or
modification in any manner that will or could adversely affect the performance
of such products or the delivery of such services as applicable at any time
hereafter.
 
    Priceline.com's internal systems include both its information technology
systems and non-information technology systems. Priceline.com has initiated an
assessment of its proprietary information technology systems, and expects to
complete any remediation and testing of all information technology systems
during 1999. With respect to information technology systems provided by
third-party vendors, priceline.com has sought assurances from such vendors that
their technology is Year 2000 compliant. All of priceline.com's material
information technology system vendors have replied to inquiry letters sent by
priceline.com stating that they either are Year 2000 compliant or expect to be
so in a timely manner.
 
                                       35
 
    Priceline.com is evaluating its non-information technology systems for Year
2000 compliance. It has not, to date, discovered any material Year 2000 issues
with respect to its non-information technology systems.
 
    Priceline.com is in the process of contacting its material seller
participants whose products or services are sold through the priceline.com
service to determine if they are Year 2000 compliant. To date, all such seller
participants have stated that they are, or expect to be, Year 2000 compliant in
a timely manner.
 
    Priceline.com's customers are individual Internet users, and, therefore,
priceline.com does not have any individual customers who are material to an
evaluation of Year 2000 compliance issues.
 
THE COSTS TO ADDRESS YEAR 2000 ISSUES
 
    Priceline.com has expensed amounts incurred in connection with Year 2000
compliance since its formation through December 31, 1998. Such amounts have not
been material. The additional costs to make any other products or services Year
2000 compliant by mid-1999 will be expensed as incurred, but are not expected to
be material.
 
    Priceline.com is not currently aware of any material operational issues or
costs associated with preparing its systems for the Year 2000. Nonetheless, it
may experience material unexpected costs caused by undetected errors or defects
in the technology used in its systems or because of the failure of a material
seller participant to be Year 2000 compliant.
 
RISKS ASSOCIATED WITH YEAR 2000 ISSUES
 
    Notwithstanding priceline.com's Year 2000 compliance efforts, the failure of
a material system or vendor, including a seller participant in the priceline.com
service, or the Internet generally, to be Year 2000 compliant could harm the
operation of the priceline.com service or prevent certain products and services
being offered through the priceline.com service, or have other unforeseen,
adverse consequences to the company.
 
    Finally, priceline.com also is subject to external Year 2000-related
failures or disruptions that might generally affect industry and commerce, such
as utility or transportation company Year 2000 compliance failures and related
service interruptions. Moreover, participating sellers in priceline.com services
might experience substantial slow-downs in business if consumers avoid products
and services such as air travel both before and after January 1, 2000 arising
from concerns about reliabilty and safety because of the Year 2000 issue. All of
these factors could have a material adverse effect on our business, financial
condition and results of operations.
 
CONTINGENCY PLANS
 
    Priceline.com has not yet developed a contingency plan to address situations
that may result if it is unable to achieve Year 2000 compliance. The cost of
developing and implementing such a plan, if necessary, could be material.
 
                                       36
 
                                    BUSINESS
 
OVERVIEW
 
    Priceline.com has pioneered a unique new type of e-commerce known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price," priceline.com collects consumer demand, in the
form of individual customer offers guaranteed by a credit card, for a particular
product or service at a price set by the customer. Priceline.com then either
communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether it can fulfill the
customer's offer on the basis of the pricing information and rules established
by the sellers. Consumers agree to hold their offers open for a specified period
of time and, once fulfilled, offers cannot be canceled. Priceline.com benefits
consumers by enabling them to save money, while at the same time benefitting
sellers by providing them with an effective revenue management tool capable of
identifying and capturing incremental revenues. By requiring consumers to be
flexible with respect to brands, sellers and product features, priceline.com
enables sellers to generate incremental revenue without disrupting their
existing distribution channels or retail pricing structures.
 
   
    Priceline.com commenced its service on April 6, 1998 with the sale of
leisure airline tickets and, during the period from launch through December 31,
1998, collected guaranteed offers for approximately 1.9 million airline tickets,
representing approximately $400.0 million in total consumer demand, resulting in
sales of approximately 134,900 airline tickets, representing approximately $30.4
million in revenue. During the two month period from January 1, 1999 through
February 28, 1999, priceline.com collected guaranteed offers for approximately
830,300 airline tickets, representing approximately $170.0 million in total
consumer demand. This demand resulted in sales of approximately 102,700 airline
tickets, representing approximately $21.1 million in revenue. The number of
offers that priceline.com accepts is affected by a variety of factors, including
the number of reasonable offers received and the level of available inventory.

Operations --
Overview."
    
 
    Priceline.com's services were expanded to include the sale of new
automobiles, on a test basis, in July 1998, hotel room reservations in October
1998 and home mortgages from a third party mortgage lender in January 1999.
Priceline.com intends to continue to leverage the priceline.com brand over the
next two years by expanding its product offerings to include rental cars,
cruises, time shares, vacation packages, insurance and other financial services
and a limited number of retail products. Through the innovative use of "adaptive
marketing programs," priceline.com also markets customer acquisition programs
for third parties, which facilitate the completion of a higher percentage of
successful transactions through the priceline.com service and generate
significant fee income for the company.
 
    Priceline.com offers products and services that are provided by
participating sellers, many of whom are leaders in their industries. Eighteen
domestic and international airlines currently participate in priceline.com's
leisure airline ticket service, including Delta, Northwest, TWA, America West
and leading international carriers. Participants in the priceline.com hotel
reservation service include Marriott, Renaissance, Sheraton, Westin and several
other nationally recognized hotel chains, as well as several important real
estate investment trusts, including Meristar, Patriot and Starwood.
Priceline.com does not publicly advertise the names of its seller participants
in its airline and hotel programs. Priceline.com's mortgage service, which is
offered through a joint marketing arrangement with LendingTree, an
Internet-based mortgage service provider, includes a network of approximately 20
mortgage lending institutions.
 
    Priceline.com earns revenues upon the completion of successful transactions
through the priceline.com service and through adaptive marketing programs
offered through the priceline.com service. The manner in which it earns revenues
varies, however, depending on the product or service sold. With respect to
airline and hotel reservation services, priceline.com determines whether to
fulfill a customer's offer
 
                                       37
 
based upon the available fares, rules and inventory that have been provided by
participating sellers through their private data bases. Upon completion of a
successful transaction, priceline.com earns the spread between the customer's
named price and the fare or rate charged by the seller. With respect to
priceline's automobile and mortgage services, a customer's offer is submitted
directly to the participating sellers who determine whether to fulfill the
offer. For these services, and for its adaptive marketing programs,
priceline.com earns fees or other payments payable by the seller and/or the
customer or by its adaptive marketing partner.
 
    Priceline.com believes that the priceline.com service already has achieved
significant consumer acceptance and widespread brand awareness. Based upon the
results of an independent research study conducted for priceline.com, the
company believes that as of September 1998, among adult Americans, the
priceline.com "name your price" business proposition was the second most
recognized e-commerce brand among the 13 leading brands included in the survey
and one of the six most recognized Internet brands among the 25 leading brands
included in the survey. Based on the study, priceline.com also believes that,
after only five months of operation, 62.5 million (or 32%) of all adult
Americans were aware of the priceline.com "name your price" proposition.
Priceline.com's strong brand awareness has been achieved without any affiliation
with an Internet portal company such as Yahoo! or Excite or a proprietary online
service such as America Online. Beyond mere name recognition, priceline.com also
believes that it enjoys high levels of consumer satisfaction among users of its
service who provide powerful word-of-mouth endorsements. In addition,
priceline.com has been featured in hundreds of news stories in national
publications such as THE NEW YORK TIMES, THE WALL STREET JOURNAL and USA TODAY.
The priceline.com service also has been awarded a four-star rating by YAHOO!
INTERNET LIFE magazine as the "most creative way to get a good deal" on leisure
airline tickets.
 
    Priceline.com believes that priceline.com's unique business model can be
applied to a broad range of products and services. Priceline.com believes that
this broad applicability of its business model, its first mover advantage, the
strength of the priceline.com brand, its network of seller participants, its
proprietary software systems and its intellectual property strategies provide it
with significant competitive advantages.
 
INDUSTRY BACKGROUND
 
    THE GROWTH OF COMMERCE ON THE INTERNET
 
    The Internet has emerged as a significant interactive medium for conducting
business. International Data Corporation, a market research firm, estimates that
the number of Internet users worldwide exceeded 97 million in 1998 and will grow
to over 319 million by the end of 2002. International Data Corporation also
estimates that annual worldwide commerce over the Internet will increase from
approximately $32.0 billion in 1998 to approximately $425.0 billion by 2002. The
factors driving this growth include the increasing number of personal computers
in homes and offices, the decreasing cost of personal computers, technological
innovations providing easier, faster and cheaper access to the Internet, the
proliferation of content and services being provided on the Internet and the
increasing use of the Internet by businesses and consumers as a medium for
conducting business. The increasing use of the Internet as a commercial medium
has been accompanied by a diversification in the type of commerce that is
conducted on the Internet and a proliferation in the types of products and
services available on the Internet.
 
    The Internet possesses a number of unique and commercially powerful
characteristics that differentiate it from traditional media: users communicate
or access information without geographic or temporal limitations; users access
dynamic and interactive content on a real-time basis; and users communicate and
interact instantaneously with a single individual or a group of individuals at
little or no cost. The Internet has created a dynamic and particularly
attractive medium for commerce, empowering consumers to gather more comparative
purchasing data than is feasible with traditional commerce systems, to shop in
ways that can be more convenient for them and to interact with sellers in many
new ways. As the Internet has become more accessible and widely used for
transactions, it has emerged as a primary business channel alongside the
telephone, paper-based communication and face-to-face interaction.

    LIMITATIONS OF TRADITIONAL PRICING MECHANISMS
 
    Under traditional retail pricing methods, sellers typically market products
to consumers under brand names at fixed retail prices. Alternatively, prices can
be established through auction processes. However, each of these forms of
seller-driven commerce has certain significant disadvantages for both sellers
and consumers. For example, in the retail pricing model, sellers who discount
prices to clear excess inventory, utilize excess capacity or increase sales
velocity, risk disruption of their existing distribution channels and damage to
their retail pricing structures. They also lose the opportunity to earn
incremental revenue from "free-riders," that is, consumers who would have been
prepared to pay the undiscounted price for the product or service, but
nevertheless obtain the benefit of the discounted price. Moreover, none of these
pricing methods allow sellers to consider the flexibility of potential buyers
before setting prices. Similarly, consumers are often forced to pay a higher
price when the seller is setting a fixed retail price for a product with added
features or under a specific brand, which the customer would otherwise have been
prepared to forgo for a lower price. Auctions force consumers to compete against
each other for the benefit of the seller, which always results in the product
being sold on the basis of the highest bid.
 
    While the Internet has become a significant medium for conducting business,
commerce presently conducted on the Internet is largely based upon traditional
pricing methods. Priceline.com believes that the vast information sharing and
communications power of the Internet creates an opportunity for significant
change in the way commerce or business is conducted.
 
THE PRICELINE.COM SOLUTION
 
    Priceline.com has developed a demand collection system that uses the
information sharing and communications power of the Internet to create a new way
of pricing products and services. Priceline.com creates a new balance between
the interests of buyers, who are willing to accept trade-offs in order to save
money, and sellers, who are prepared to generate incremental revenue by selling
products at below retail prices, provided that they can do so without disrupting
their existing distribution channels or retail pricing structures.
Priceline.com's demand collection system allows consumers to name the price they
are prepared to pay when submitting an offer for a particular product or service
within a specified range of substitutability. Priceline.com then either
communicates such offers to multiple sellers who determine whether to accept the
customer's offer or accesses participating sellers' private databases to
determine whether it can fulfill the customer's offer on the basis of the
pricing information and rules established by the sellers. Consumers agree to
hold their offers open for a specified period of time to enable priceline.com to
fulfill their offers from inventory provided by participating sellers. Once
fulfilled, offers generally cannot be canceled. This system uses the flexibility
of buyers to enable sellers to accept a lower price in order to sell excess
inventory or capacity or to increase sales velocity. Priceline.com believes that
its demand collection system addresses the limitations inherent in traditional
pricing mechanisms in a manner that offers substantial benefits to both buyers
and sellers.
 
    The principal advantages of the priceline.com system include the following:
 
    - COST SAVINGS AND PREFERRED METHOD OF PURCHASING FOR CONSUMERS.
      Priceline.com's demand collection system allows consumers to save money in
      a simple and compelling way--"name your price." Buyers effectively trade
      off flexibility about brands, product features and/or sellers in return
      for prices that are lower than those that can be obtained at that time
      through traditional retail distribution channels. Priceline.com believes
      that in many cases, such as purchasing a new car or obtaining a home
      mortgage, naming your own price over the Internet represents a preferred
      purchasing method to traditional retail channels, which may involve
      comparison shopping among a complex array of alternative features,
      sometimes protracted negotiations and dealings with numerous brokers or
      sales representatives. Priceline.com also believes that naming your price
      over the Internet is a preferred purchasing method to auctions, which
      result in a product being sold on the basis of the highest bid.
 
                                       39
 
    - INCREMENTAL REVENUE FOR SELLERS. Sellers use priceline.com as a revenue
      management tool to generate incremental revenue without disrupting their
      existing distribution channels or retail pricing structures. Priceline.com
      requires consumers to be flexible with respect to brands, such as a
      willingness to fly on any major airline; and/or product features, such as
      a willingness to fly at any time of the day; and/or seller, such as any
      BMW dealer in a specific geographic area. As a result, sellers' brands are
      not revealed to customers prior to the consummation of a transaction,
      thereby protecting their brand integrity. This shielding of brand identity
      enables sellers to accept offers at discounted prices through
      priceline.com without cannibalizing their own retail sales by publicly
      announcing discount prices and without competing against their own
      distributors. In effect, priceline.com serves as a discreet and insulated
      channel of distribution. Sellers are further protected by the fact that
      each transaction is independent and the prices at which offers are
      accepted are not revealed to subsequent users of the priceline.com
      service. Priceline.com gives sellers the ability to exercise a greater
      degree of pricing flexibility without trading high-margin sales for
      low-margin sales, thereby enabling sellers to expand their total revenues
      and, in some cases, gain market share at the expense of non-participating
      competitors.
 
    - PROPRIETARY SELLER NETWORKS. Priceline.com assembles proprietary networks
      of industry leading sellers that represent high quality brands, such as
      Delta, Northwest, TWA, America West, Marriott, Renaissance, Sheraton and
      Westin. By establishing attractive networks of seller participants with
      reputations for quality, scale and national presence, priceline.com
      fosters increased participation by both buyers and sellers. Each
      participant in these unique seller networks is willing to consider and
      accept consumer offers at prices that are below its retail prices.
      Moreover, by shielding the seller's brand and not revealing the final
      selling price to other consumers, priceline.com encourages participating
      sellers to be aggressive in their pricing. Priceline.com believes that as
      more and more sellers in an industry join the priceline.com service, other
      industry participants will want to join the system.
 
    - GUARANTEED CONSUMER DEMAND FOR SELLERS. Each customer who makes an offer
      through priceline.com must guarantee his offer with a major credit card.
      The guaranteed aspect of the demand is attractive to sellers because they
      know that priceline.com offers them a confirmed sale whenever they accept
      a buyer's offer. Sellers can be sure that collected demand represents
      willing buyers, at each named price, rather than browsing shoppers who
      have made no commitment to purchase. Priceline.com's database of consumer
      offers also provides sellers with valuable market information about the
      precise quantities of latent demand at each price point below their retail
      prices.
 
    - BROAD APPLICATIONS ACROSS MULTIPLE MARKETS. In contrast to many e-commerce
      companies that are building brands in vertical categories or groups of
      related categories, priceline.com believes that its e-commerce business
      model has horizontal application to products and services in a wide range
      of industries. Priceline.com further believes that the broad applicability
      of the priceline.com service and the strength of the priceline.com brand
      afford it the opportunity to obtain substantial economies of scale and
      offer the potential for priceline.com to become a major new channel of
      distribution. The breadth of potential applications of the priceline.com
      business model also is enhanced by various cross-selling opportunities,
      since priceline.com expects that consumers who successfully complete
      transactions through priceline.com will return to priceline.com to
      purchase other products and services.
 
                                       40
 
THE PRICELINE.COM GROWTH STRATEGY
 
    Priceline.com's objective is to continue to expand the priceline.com
business and to establish priceline.com's demand collection system as a leading
source for the purchase of products and services on the Internet. The key
elements of priceline.com's strategy are as follows:
 
    - STRENGTHEN THE PRICELINE.COM BRAND. Priceline.com intends to establish
      priceline.com as the leading consumer brand for buyer-driven commerce over
      the Internet. To achieve this objective, priceline.com intends to continue
      to pursue an aggressive brand development strategy through mass market and
      targeted advertising and promotions, press coverage and strong
      word-of-mouth support. While priceline.com believes it is already one of
      the most recognized e-commerce brands among adult Americans, priceline.com
      believes that it can expand the public's association with the
      priceline.com "name your price" proposition to a broad range of products
      and services.
 
    - LEVERAGE THE PRICELINE.COM BRAND OVER NUMEROUS PRODUCTS AND SERVICES.
      Priceline.com intends to leverage the priceline.com brand across numerous
      products and services to achieve significant revenue scale and growth. In
      contrast to most e-commerce businesses that operate in one or two
      "vertical" markets, priceline.com is a "horizontal" commerce system that
      can benefit both buyers and sellers in a broad range of industries.
      Priceline.com's strategy is to make available multiple product and service
      offerings at a single Web site under a common brand to take advantage of
      these market opportunities. Over the next two years, priceline.com intends
      to offer products and services in four sectors of the economy where its
      demand collection system is particularly well suited. These sectors are:
 
       - travel, including leisure airline tickets and hotel rooms, rental cars,
         "all-inclusives" resorts, cruises and time shares;
 
       - financial services, including home mortgages, credit card balance
         consolidation and automobile and life insurance;
 
       - automobile sales and related financing; and
 
       - retail products, including computers, home electronics and other
         consumer products.
 
      In these sectors, the priceline.com service currently offers leisure
      airline tickets, hotel rooms, home mortgages and, on a test basis,
      automobiles. Given the size and scope of these markets, priceline.com
      believes it can achieve a large revenue base and sustain revenue growth by
      capturing even a small portion of the excess unsold inventory or capacity
      in these sectors and by capturing even relatively small amounts of market
      share from traditional seller-driven channels of retail distribution.
 
    - EXPAND SELLER PARTICIPANT NETWORKS. Priceline.com intends to continue to
      expand its alliances with major seller participants selected for
      reputation, quality and national presence to create proprietary seller
      networks for each of its major products and services. A critical element
      of the priceline.com business has been priceline.com's ability to
      demonstrate to its seller participants that priceline.com can generate
      incremental revenues for sellers without disrupting their existing
      distribution channels or retail pricing structures. Priceline.com intends
      to form and maintain alliances with industry leaders by designing its
      products and services in a way that requires consumers to accept some
      trade-offs from currently available retail product offerings in return for
      lower prices. Such trade-offs typically include not knowing the identity
      of the seller or brand prior to the acceptance of a customer's offer by a
      seller.
 
    - ENHANCE SITE FUNCTIONALITY AND INCREASE CONSUMER USAGE. Priceline.com
      intends to frequently update and enhance the features of the priceline.com
      service. Priceline.com continually monitors feedback from consumers and
      frequently adds new features to further refine and simplify the buying
      process. Priceline.com also receives offers and provides customer service
      by telephone to
 
                                       41
 
      assist consumers in the offer process. By continuing to increase the
      functionality of the service and enhance the consumer experience,
      priceline.com believes that it will continue to increase customer usage
      and loyalty.
 
    - EXPAND ADAPTIVE MARKETING PROGRAMS. Priceline.com intends to further
      develop and expand what it refers to as "adaptive marketing programs."
      Adaptive marketing programs include two distinct initiatives. "Adaptive
      promotions" allow consumers to increase the amount of their offers, and
      thus their likelihood of success, at no additional cost by participating
      in sponsor promotions during the process of making a priceline.com offer.
      For example, a customer making an offer to buy an airline ticket can
      increase the amount of his offer by a stated amount by applying online for
      a credit card issued by one of priceline.com's strategic sponsors. These
      promotions have the effect of increasing the percentage of successful
      offers at no additional cost to the customer, while at the same time
      enabling priceline.com to earn significant fee income, which it can use to
      offset the sale of products and services below its unit cost. The second
      type of adaptive marketing program is referred to as "adaptive cross
      selling" and utilizes cross selling of multiple products to increase the
      number of successful transactions.
 
    - INCREASE FINANCIAL RETURNS OVER TIME. While it is inherent in the nature
      of priceline.com's business model that not all offers will be acceptable
      to sellers, an integral part of priceline.com's strategy is to ensure that
      a high percentage of reasonable offers get accepted, thereby increasing
      financial returns while reinforcing the priceline.com service. As
      consumers have become more familiar with the service, priceline.com has
      been able to increase the percentage of offers it satisfies and expects
      this trend to continue. As its revenue base grows, priceline.com intends
      to increase its financial returns over time. Priceline.com's revenue model
      for travel services enables it to balance revenue growth against gross
      profit margins, thereby enhancing its ability to manage a targeted gross
      margin as a percentage of revenues. Priceline.com initially intends to
      emphasize revenue growth over profit margins in order to achieve
      significant revenue scale and to further strengthen the priceline.com
      brand. However, over time, as its revenue base increases, priceline.com
      believes it will be able to capture a greater portion of the incremental
      profit that it generates for participating sellers and thereby increase
      its profit margins and financial returns.
 
    - EXPLORE INTERNATIONAL EXPANSION. Priceline.com believes that the
      international scope of the Internet and the global demand for the types of
      products and services that it intends to make available through
      priceline.com presents opportunities to expand its service
      internationally. Given the anticipated continued increase in use of the
      Internet throughout the world, priceline.com intends to explore avenues
      and strategies for international expansion. It believes that joint
      ventures and licensing arrangements with international partners are likely
      to be the preferred methods of international expansion, as they will
      enable priceline.com to combine its expertise in demand collection systems
      with its partners' expertise in their local markets.
 
THE PRICELINE.COM BUSINESS MODEL
 
    Priceline.com believes that its demand collection system is a powerful new
business model for conducting commerce on the Internet. The priceline.com
business model is designed to allow consumers to save money on a wide range of
products and services by trading flexibility regarding brands, product features
and/or sellers in return for being able to buy products and services at prices
that are lower than those charged through traditional retail channels of
distribution. The priceline.com business model motivates sellers to offer
products through priceline.com at below their retail prices by enabling them to
generate incremental revenue while protecting their existing channels of
distribution and retail pricing structures.
 
    The priceline.com business model enables the company to earn substantial
revenues without charging customers for submitting offers through, or charging
sellers for participating in, the priceline.com system. Priceline.com has the
flexibility to earn fixed or percentage based fees by serving as an intermediary
on the
 
                                       42
 
sale of products or services, or to earn the spread between the customer's offer
and the cost of a product or service by serving as principal in a transaction.
Consumer fees are payable only upon completion of successful transactions. This
unique revenue structure enables priceline.com to manage the level of gross
margins and, as appropriate, balance revenue growth with margin growth.
 
    In addition to its unique revenue structure, the defining elements of the
priceline.com business model are the following:
 
    - the buyer specifies or accepts a RANGE OF SUBSTITUTABILITY among brands,
      product features and/or sellers; for example, he agrees to stay at any
      three-star hotel in a certain area, agrees to fly at any time of the day
      or agrees to purchase a new car from any factory-authorized dealer;
 
    - the buyer NAMES THE PRICE he is prepared to pay for the products or
      services within the specified range of substitutability;
 
    - the buyer GUARANTEES HIS OFFER for a specified time period by securing all
      or a portion of his potential payment for the product or service with a
      major credit card;
 
    - companies sell products or services at prices below their currently
      available retail prices using priceline.com as a BRAND SHIELD to protect
      their retail pricing structures and channels of distribution;
 
    - each guaranteed offer can be consummated with products or services from
      any of a GROUP OF SELLERS; and
 
    - offers made through priceline.com are held open for a specified period of
      time, and CANNOT BE CANCELED by either the seller or the buyer.
 
    The priceline.com consumer proposition is simple and compelling: realize
immediate savings by using the Internet to name your own price when you are
willing to be flexible about brands, product features and/or sellers. A central
premise of the priceline.com consumer proposition is that in many product and
service categories there are a significant number of consumers for whom brands,
product features or sellers are interchangeable, particularly if agreeing to a
substitution among brands or sellers will result in saving money. For example,
priceline.com believes that many leisure travelers are relatively indifferent
about the brand of major airline they fly. Similarly many consumers are
indifferent to which financial services company provides them with a credit card
or home mortgage. Priceline.com also believes that many consumers prefer not to
spend time and effort engaged in an evaluative process among similar products,
brands or sellers, which they consider to be substitutable. Finally,
priceline.com is appealing to some consumers because it does not charge a
customer to submit an offer, and priceline.com's Web site provides convenient
access, available 24 hours a day, seven days a week.
 
    Priceline.com believes that the collection of large volumes of consumer
demand is essential to building networks of multiple sellers. Priceline.com also
believes that it is important that all of the demand it collects is GUARANTEED
by the buyers, that offers must be held open for a specified time period and
that once an offer is accepted it generally cannot be canceled or the purchase
price refunded. This approach assures sellers that a customer's offer is bona
fide and that once an offer is accepted, the seller will generate an immediate
sale, rather than an invitation to further negotiation or comparison shopping.
 
    The priceline.com business model is predicated on the assumption that
sellers almost invariably have excess inventory or capacity that they would sell
at lower prices, if they could do so without either lowering their prices to
their retail customers or advertising that lower prices are available.
Priceline.com allows sellers to capture demand below their retail "price line,"
without allowing retail customers who might be willing to pay more to "free
ride" down to the lower price. The ability to offer prices below the retail
price line generates incremental revenue by accessing buyer segments otherwise
priced out of the market and, in certain cases, by capturing market share from
nonparticipating competitors. Finally, priceline.com's database of consumer
offers benefits sellers by providing them with valuable market information about
the precise quantities of latent demand at each price point below their retail
prices.
 
                                       43
 
    Priceline.com believes that its demand collection system is ideally suited
to industries characterized by low variable costs relative to total cost, which
results in high profit contribution margins and provides sellers with a strong
incentive to sell products at prices below their retail prices to generate
incremental sales, provided that they can do so without threatening their
existing distribution channels or retail pricing structures. Low variable costs
frequently exist in industries with expiring or rapidly aging inventory.
Priceline.com also believes, however, that its demand collection system will
prove to be effective even in industries that are not characterized by rapidly
aging inventories and low variable costs because a significant number of
consumers will prefer the relative cost savings, ease of use and convenience of
priceline.com's name your price system to traditional retail distribution
channels, and sellers will be attracted to the potential of the priceline.com
service to increase sales velocity, which is often a significant factor in the
success of businesses in these industries.
 
    Priceline.com believes that markets characterized by a large degree of
brand, product feature or seller substitutability are substantial and include
both those in industries characterized by high profit contribution margins and
industries in which many consumers are dissatisfied with traditional retail
distribution methods. In the business-to-consumer market, travel, new car sales,
financial services and many retail products offer substantial ranges of
substitutability in consumers' minds. In the business-to-business market, long
distance service, media sales and office supplies are subject to high degrees of
product or brand substitutability. In the consumer-to-consumer market, there are
often multiple sellers that are ready, willing and able to offer new or nearly
new products that consumers consider substitutable. Priceline.com believes that
its business model can be applied to each of these markets, thereby providing it
with considerable potential for long term growth.
 
PRODUCTS AND SERVICES
 
    Priceline.com launched the priceline.com service on April 6, 1998 with the
sale of leisure airline tickets. Since that time, the priceline.com service has
been expanded to include the sale of new automobiles, on a test basis, in July
1998, hotel room reservations in October 1998 and home mortgages from a third
party mortgage lender in January 1999. Priceline.com also intends to expand its
product offerings over the next two years to include other leisure travel
products such as rental cars, cruises, time shares, and vacation packages;
automobile and personal insurance and other financial services products; and
certain retail products such as computers, home electronics and other consumer
products.
 
    TRAVEL SERVICES
 
    LEISURE AIRLINE TICKETS.  Priceline.com commenced its service with the sale
of leisure airline tickets. The number of airlines participating in
priceline.com's airline ticket service has increased substantially since the
launch of the business, from an initial group of two domestic airlines and four
international airlines, to a total of five domestic airlines and 13
international airlines. Priceline.com also purchases and resells a small
percentage of its tickets from airline ticket consolidators. Airlines
participate in priceline.com's airline ticket service by making available to
priceline.com unpublished fares and, in some cases, dedicated or special
inventory. Priceline.com does not publicly advertise the names of airlines
participating in its airline ticket service.
 
    Consumers can make offers to purchase airline tickets through the
priceline.com Web site or the 1-800-Priceline call center. The vast majority of
all airline ticket requests are made through priceline.com's Web site. To make
an offer, the customer specifies (1) the origin and destination of the trip, (2)
the dates on which he wishes to depart and return and (3) the price he is
willing to pay, and guarantees the offer with a credit card. Consumers must
agree to, among others, the following conditions:
 
    - to fly on any major full-service airline, which is defined by the United
      States Department of Transportation;
 
    - to leave at any time of the day on their desired dates of departure and
      return;
 
                                       44
 
    - to purchase only round trip economy class tickets between the same two
      points of departure and return;
 
    - to accept up to one stop or connection;
 
    - to receive no frequent flier miles or upgrades; and
 
    - to accept tickets that cannot be refunded or changed.
 
    Consumers are informed that they can increase their chances of obtaining the
desired ticket by accepting greater flexibility, such as accepting flights
outside of priceline.com's normal flight times or accepting more than one stop
or connection. Consumers also are given the opportunity to have their offers
increased by a specified dollar amount, and thereby increase the likelihood of
success, if they agree to participate in an adaptive promotion during the
process of submitting their offers, such as applying for a credit card or
subscribing to a magazine. In order to encourage reasonable initial offers,
consumers are not permitted to make revised offers for an identical itinerary
within seven days of an unsuccessful offer.
 
    When priceline.com receives an offer, it determines whether to fulfill the
offer based upon the available fares, rules and inventory that have been
provided by participating airlines. Such fares and rules are filed by
participating airlines in a private database known as SecureRate within the
Worldspan central reservation system. As a certified travel agency,
priceline.com also has access to the published "tariff" fares of all airlines,
including those not participating in the priceline.com service, although
priceline.com currently does not sell tickets purchased pursuant to published
tariff fares. If a qualifying airfare is identified, a search in Worldspan is
initiated to find seat availability on the requested dates of travel. Where more
than one seller is able to fulfill the customer's offer, priceline.com awards
the business based on an allocation protocol.
 
    A customer is notified whether his offer has been accepted within one hour
for domestic flights and within twenty-four hours for international flights. If
priceline.com is able to obtain an airline ticket within the parameters
specified by the customer, the customer's credit card is charged for the amount
of the customer's offer and the ticket is delivered to the customer by the
delivery method specified by the customer. Approximately 90% of the tickets
issued through priceline.com are electronic tickets for which there is no
delivery charge. Priceline.com does not charge a fee to either the customer or
the airline, but earns the spread, if any, between the customer's offered price
and the cost to purchase the ticket from the airline.
 
   
    HOTELS.  In October 1998, priceline.com launched its second travel service,
which allows consumers to name their price for hotel room reservations.
Priceline.com's hotel reservation service currently is available in more than
220 cities, including over 30 metropolitan areas, which include Atlanta, Boston,
Chicago, Los Angeles, New York, Orlando and San Francisco. Priceline.com intends
to expand its hotel reservation service during 1999 to include substantially all
major cities and metropolitan areas in the United States and various
international destinations. Seller participants in the hotel reservation service
include several of the most significant national hotel chains, including
Marriott, Renaissance, Sheraton and Westin, as well as several important real
estate investment trusts, including Meristar, Patriot and Starwood, and
independent property owners. Hotels participate by filing private discounted
rates with related inventory control rules in priceline.com's private database
in the Worldspan centralized reservation system for hotel rooms. These rates
generally are not available to the general public or to consolidators and other
discount distributors who sell to the public.
    
 
    Priceline.com's hotel reservation service operates in a manner similar to
its airline ticket service. Consumers are required to accept certain trade-offs
with respect to brands or product features in return for saving money. For
example, consumers are required to accept a reservation in any hotel within a
specified geographic area within a designated "class" of service (1, 2, 3, 4 or
5-star) and must accept limitations on changes and cancellations. Priceline.com
determines the class of service for each participating hotel based upon
published industry reports, the amenities available at each property and other
factors
 
                                       45
 
such as age and decor. As with the airline ticket service, the target market for
priceline.com's hotel reservation service is the leisure travel market.
 
    Consumers can make offers for a hotel reservation through the priceline.com
Web site or 1-800-Priceline call center. To make an offer, the customer (1)
specifies (a) his dates of stay, (b) the metropolitan area, including geographic
zones within that metropolitan area, (c) the class of hotel service and (d) the
price he is willing to pay; and (2) guarantees the offer with a credit card.
Upon receipt of an offer for a hotel reservation, priceline.com systematically
compares the offer with rates and inventory rules provided by sellers through
their reservation systems and determines whether to fulfill the offer based upon
available inventory. Within a specified time, which currently is one hour, the
customer is notified whether his offer has been accepted. When selling a hotel
reservation, priceline.com earns the spread between the consumer's offer price
and the price charged to the company by the hotel. Priceline.com also earns fee
income from adaptive promotions that it makes available to consumers during the
course of submitting an offer for a hotel reservation.
 
    The dynamics of the hotel industry are similar to those of the airline
industry in that both industries are characterized by expiring inventory and low
marginal costs so that the sale of any excess inventory provides a significant
contribution to profits. As with the airline industry, a significant amount of
available inventory in the hotel industry expires unsold. Priceline.com also
believes that consumers are willing to trade off brand identity for lower rates
with a specified class of hotel service and that such industry dynamics make
priceline.com's demand collection system particularly well-suited to the hotel
industry. Priceline.com also believes that the hotel reservation service will
create opportunities for cross-selling to leisure travelers who purchase airline
tickets through priceline.com.
 
    OTHER TRAVEL SERVICES.  Priceline.com intends to expand its products and
services within the leisure travel industry over the next two years to encompass
the rental car, cruise, all-inclusive resort, time share and vacation package
segments.
 
    FINANCIAL SERVICES PRODUCTS
 
    HOME MORTGAGES.  Priceline.com introduced its home mortgage service in
January 1999. Priceline.com's mortgage service allows consumers to name their
interest rate for mortgages of a specified term, including purchase money
mortgages, refinancings and home equity loans. LendingTree, an Internet based
mortgage service provider, is priceline.com's joint marketing partner in
connection with its mortgage service. Under priceline.com's agreement with
LendingTree, priceline.com is responsible for maintaining the mortgage service
on the priceline.com Web site and for consumer marketing. LendingTree serves as
the mortgage broker and operates the back-end processing system, which presents
offers received through priceline.com to multiple mortgage lending institutions
for consideration. LendingTree maintains its own online mortgage service, which
includes a network of over 20 mortgage lending institutions. See "-- Strategic
Alliances -- Marketing Agreement for Mortgage Services."
 
    To obtain a home mortgage through the priceline.com service, consumers
access the priceline.com Web site and specify the amount of the loan, the term
and the interest rate they are willing to pay. Consumers complete a simplified
loan application as part of the process of making an offer. In connection with
making an offer, consumers are required to guarantee with a major credit card
the payment of a fee of $200, to be credited against closing costs if their
offer is accepted. Priceline.com transmits each offer to LendingTree, which in
turn presents the offer to multiple lenders who can either accept the offered
terms, or return a counteroffer to the consumer. Priceline.com notifies the
customer within 48 hours whether his offer has been accepted. Upon the closing
of a mortgage placed through priceline.com's mortgage service, LendingTree
receives a fee from the lending institution, and priceline.com receives a fee
from LendingTree.
 
    According to industry data published in 1998, approximately $1.1 trillion of
home mortgages were entered into in the United States in 1996. Priceline.com
believes that consumers are largely indifferent to
 
                                       46
 
which mortgage issuer provides their mortgage and seek merely to obtain the
lowest cost in the most efficient manner. Moreover, comparison shopping among
the hundreds of mortgage lenders can be a frustrating experience for consumers.
Priceline.com believes the priceline.com mortgage service will provide consumers
with a simple and efficient vehicle for obtaining the interest rate they seek
through a preferable purchasing process. For lenders, the priceline.com mortgage
service will provide guaranteed demand from consumers who are committed to buy
and will submit that demand in a format that can be reviewed and evaluated by
the lender with minimal variable costs.
 
    OTHER FINANCIAL SERVICES PRODUCTS.  Priceline.com intends to expand its
products and services within the financial services industry over the next two
years to include unsecured personal loans, credit card balance consolidations
and automobile and life insurance policies. As with its other products and
services, priceline.com intends to expand its financial product services by
entering into strategic relationships with leading industry participants.
Priceline.com believes its financial product services will have broad
demographic appeal among consumers who seek to obtain the most attractive
economic terms in the most efficient manner from what they perceive to be
substitutable suppliers.
 
    NEW CAR SALES
 
    Priceline.com introduced a new car sales service on a test basis in the New
York metropolitan area in July 1998. Priceline.com is using the New York market
to learn more about the automobile sales over the Internet and to develop
product features and systems support. In the first half of 1999, priceline.com
intends to introduce its new car sales service in a prototype market, which
presently is expected to be a city with a population of approximately one
million. Once the service's product features have been refined and its
performance expectations have been achieved in this prototype market,
priceline.com expects to implement a gradual roll-out to additional metropolitan
markets in the United States. Priceline.com's new car sales service currently
does not offer automobile financing. Because a significant majority of new car
buyers finance their purchase, priceline.com intends to add a financing feature
to its program, for both leasing and lending, prior to a broader roll-out of the
service, including a "budget worksheet" that will assist customers in
determining what cars they can afford to purchase.
 
    Priceline.com's new car sales service accepts offers for every major brand
of automobile. To purchase a new car through the priceline.com service,
consumers name the price for a new car with specified model options, and agrees
to purchase such car from any factory authorized dealer within a specified
geographic radius. To help consumers submit reasonable requests, both the
manufacturer's suggested retail price and the dealer invoice price for the
vehicles and options requested are displayed on the priceline.com Web site. Upon
receiving an offer for a new car, priceline.com transmits the customer's offer
to factory authorized dealers within the specified geographic radius, without
disclosing the identity of the customer. Priceline.com directs the sale to the
first dealer that notifies the company that it is willing to accept the
customer's offer. Priceline.com then notifies the customer to pick up the
vehicle from that dealer and the transaction is closed directly between them.
 
    Due to the numerous features and options on a new automobile, the range of
product substitutability that consumers will accept is lower in the case of new
cars than with airline tickets or hotels. As a result, a dealer that may not be
able to precisely fulfill a customer's offer is permitted to make a counteroffer
through priceline.com. The counteroffer may specify a different product package
or price. The customer is free to accept or reject such a counteroffer. The
customer also is permitted to submit an additional offer through priceline.com.
 
    Once an offer for a new car is accepted by a dealer, the consumer completes
the transaction directly with the dealer and receives the same standard
manufacturer's warranty and other terms that are available with respect to any
new car purchased at that dealer. When a sale is completed, priceline.com is
paid a fee, which is currently $25, from the customer and an additional fee from
the auto dealer. If the customer fails to consummate the transaction within 14
business days of being notified that an offer is accepted, the
 
                                       47
 
customer is charged a cancellation fee, which is currently $200, half of which
is payable to priceline.com with the other half payable to the dealer.
 
    Priceline.com believes that, for many consumers, purchasing an automobile
through priceline.com's new car sales service will be a preferred purchasing
method compared to traditional retail channels which often involve protracted
negotiations with numerous dealers, some of which may utilize aggressive sales
tactics. Priceline.com also believes that many automobile dealers will view the
priceline.com service as an attractive way to generate incremental sales through
a low cost distribution channel.
 
    The priceline.com new car sales service is differentiated from other
Internet car sales services, which serve as lead generators for participating
car dealers. Under such services, multiple dealers may contact the customer in
response to the customer's inquiry to the Internet service. By contrast,
priceline.com's new car sales service does not reveal the identity of the
customer to the auto dealer until the dealer has accepted the customer's offer.
Furthermore, in contrast to other Internet car sales services, dealers are not
required to pay a participation fee to review offers from the priceline.com
service.
 
ADAPTIVE MARKETING PROGRAMS
 
    Priceline.com has developed adaptive marketing programs to help bridge the
gap between consumer offers and seller prices, provide users of the
priceline.com service with other desired products, and generate additional
revenue for the company. These programs also serve as an integral part of
priceline.com's strategy of building customer loyalty.
 
    Priceline.com intends to further develop and expand its adaptive marketing
programs, which presently include two distinct initiatives. The first, which it
refers to as "adaptive promotions," allows consumers to increase the amount of
their offers, and thus their likelihood of success, at no additional cost by
participating in sponsor promotions during the process of making a priceline.com
offer. For example, a customer making an offer to buy an airline ticket can
immediately increase the amount of his offer by $50 by applying online for a
credit card. If the customer obtains the requested ticket, he still pays only
the amount contained in his original offer. For example, if a customer makes an
offer to purchase a round trip ticket from New York to Chicago for $200 and, in
the process of submitting that offer, he applies for a credit card, the offer
would be submitted at $250, but the customer would have to pay only $200 for the
ticket.
 
    The second type of adaptive marketing program is referred to as "adaptive
cross selling" and utilizes cross selling of multiple products to increase the
number of successful transactions. For example, a customer whose offer for an
airline ticket was slightly below acceptable levels could be offered a second
related product such as a hotel room reservation or a rental car day at a
combined price that provided an acceptable margin for the sellers of both
products and for priceline.com.
 
    Priceline.com's principal adaptive promotion offers consumers the ability to
apply for a credit card issued by Capital One Bank while submitting offers
through priceline.com. In connection with this promotion, priceline.com is paid
a fee by Capital One for each qualifying credit card application. Substantially
all of priceline.com's adaptive marketing revenues to date have been derived
from the Capital One promotion. Priceline.com has entered into an agreement in
principle with First USA Bank, one of the nation's leading credit card issuers,
under which First USA would replace Capital One as priceline.com's strategic
partner in its credit card adaptive marketing program. Priceline.com also has a
co-marketing agreement with E*TRADE Group, Inc. to establish an adaptive
marketing program under which E*TRADE will compensate priceline.com for offering
priceline.com customers the opportunity to open an account with E*TRADE while
visiting or making an offer on the priceline.com Web site. In addition,
priceline.com has an adaptive marketing promotion for magazine subscriptions
pursuant to a revenue sharing arrangement with NewSub Services, Inc. See "Risk
Factors -- We are Dependent on Adaptive Marketing Programs" and "--Strategic
Alliances -- Adaptive Marketing Alliances."
 
                                       48
 
MARKETING AND BRAND AWARENESS
 
    Priceline.com has established itself as a leading e-commerce brand through
an aggressive marketing and promotion campaign. From inception through December
31, 1998, priceline.com incurred $24.4 million for sales and marketing expense.
It intends to continue to pursue an aggressive marketing strategy designed to
promote brand awareness and the concept that consumers can save money on a wide
range of products and services through priceline.com. Underlying priceline.com's
marketing strategy is the company's belief that its target market is all
consumers, not just Internet-savvy consumers. Substantially all of such spending
has been for radio and newspaper advertising. Priceline.com's campaign features
the actor William Shatner as its spokesperson.
 
    Priceline.com supplements its paid advertising and promotion with targeted
media coverage. Priceline.com has been featured in hundreds of news stories in
national publications such as THE NEW YORK TIMES, THE WALL STREET JOURNAL and
USA TODAY, reflecting the intuitive appeal of the priceline.com business model
and its strong word-of-mouth support. In addition, priceline.com engages in
grass roots marketing such as promotional events on college campuses and
co-promotions with popular media such as MTV.
 
    Priceline.com believes that the priceline.com service has achieved
widespread brand awareness. Based upon the results of an independent research
study conducted for priceline.com, the company believes that, as of September
1998, among adult Americans, the priceline.com "name your price" business
proposition was the second most recognized e-commerce brand among the 13 leading
brands included in the survey and one of the six most recognized Internet brands
among the 25 leading brands included in the survey. Based on the study,
priceline.com also believes that, after only five months of operation, 62.5
million (or 32%) of all adult Americans were aware of the priceline.com "name
your price" proposition. Priceline.com's strong brand awareness has been
achieved without any affiliation with an Internet portal company such as Yahoo!
or Excite or a proprietary online service such as America Online. Priceline.com
also believes that it enjoys high levels of consumer satisfaction among users of
its service who provide powerful word-of-mouth endorsements.
 
STRATEGIC ALLIANCES
 
    AIRLINE ALLIANCES AND RELATIONSHIPS
 
    Priceline.com has entered into Airline Participation Agreements with five
domestic and 13 international airlines. The Airline Participation Agreements do
not commit the airlines to provide tickets for any particular routes or at a
discount to their retail prices, but outline the terms and conditions under
which ticket inventory provided by the airlines may be sold. Such terms and
conditions include the following:
 
    - the tickets must be non-refundable, non-endorsable and non-changeable;
 
    - all travel must be round-trip between the same two points of departure and
      return, with no stopovers permitted;
 
    - the tickets are not eligible for frequent flyer mileage or upgrades;
 
    - consumers must agree to accept up to one stop or connection on both their
      departing and return flights;
 
    - consumers must be willing to fly on any participating airline;
 
    - consumers must be willing to depart at any time after 6 a.m. and land any
      time before 10 p.m. on the requested dates;
 
    - all offers must be guaranteed with a major credit card; and
 
    - consumers are limited in their ability to make multiple offers with
      respect to the same travel itinerary.
 
                                       49
 
    The Airline Participation Agreements generally are subject to termination
upon 30 days' notice by priceline.com or the airline. While priceline.com's
agreement with Delta nominally has a ten-year term, the Agreement does not
impose any material obligations on Delta. In particular, Delta is not at any
time obligated to supply airline tickets to priceline.com and may supply airline
tickets to priceline.com's competitors at any time, without offering any airline
tickets to priceline.com, or may offer tickets to priceline.com's competitors at
more favorable prices than those offered to priceline.com.
 
    In addition to the Airline Participation Agreements, priceline.com entered
into a related agreement with Delta which provides, among other things, certain
incentives designed to encourage Delta to increase its participation in
priceline.com's buying service. For example, Delta is entitled to share in
revenue generated from airline ticket sales on Delta if priceline.com's gross
margin on such sales exceeds approximately 12% in any calendar quarter. In
addition, priceline.com is required to use the highest qualifying fare to
fulfill ticket requests allocable to Delta, subject to an agreed minimum profit
margin to priceline.com. The agreement also requires, subject to various
exceptions, Delta's approval of the addition of new carriers to the
priceline.com service and restricts both the volume of tickets that may be sold
and the routes for which tickets may be offered by specified carriers through
the priceline.com service. Delta also may require the exclusion of specific
markets in order for certain other airlines to participate. Further,
priceline.com is required to license its buyer-driven commerce system to Delta
on a non-exclusive basis and on commercially reasonable terms under specified
conditions. In addition, priceline.com's ability to transfer or license its
intellectual property to other travel providers is limited in the manner set
forth in the agreement.
 
   
    In connection with the Airline Participation Agreement with Delta,
priceline.com also issued a warrant to Delta to purchase up to 18,619,402 shares
of common stock at an exercise price of approximately $0.93 per share. The Delta
warrant will become exercisable at the earlier of December 31, 2005, or Delta's
achievement of certain performance thresholds of ticket sales.
    
 
    Priceline.com also has issued to several participating airlines warrants to
purchase an aggregate of 2,187,500 shares of common stock, comprised of warrants
to purchase 937,500 shares of common stock at an exercise price of $3.20 per
share and warrants to purchase 1,250,000 shares of common stock at an exercise
price of $6.40 per share. The warrants having an exercise price of $3.20 per
share become exercisable 210 days after the completion of this offering. With
respect to the warrants having an exercise price of $6.40 per share, warrants
relating to one-half of the underlying shares become exercisable on December 31,
1999, and warrants relating to the remaining underlying shares become
exercisable on December 31, 2000, subject to earlier termination of such
warrants in the circumstances identified in the warrant agreement.
 
    MARKETING AGREEMENT FOR MORTGAGE SERVICES
 
    In connection with priceline.com's home mortgage service, priceline.com has
entered into a joint marketing relationship with LendingTree, an Internet based
mortgage service provider. Under this arrangement, priceline.com is responsible
for maintaining the mortgage service for the priceline.com Web site and for
consumer marketing. LendingTree provides the back-end processing system, which
presents the priceline.com offers to multiple mortgage lending institutions for
consideration.
 
    Under the terms of the Internet Marketing and Licensing Agreement, effective
as of August 1, 1998, between priceline.com and LendingTree, priceline.com
receives the majority of the net revenue generated by the mortgage program, and
the balance is earned by LendingTree. LendingTree is responsible for providing
(1) the substantive mortgage content of the mortgage service for the
priceline.com Web site; (2) a network of lenders to participate in the mortgage
program; (3) customer service; and (4) the software required to effect a
communication system between priceline.com, LendingTree and the participating
lenders. LendingTree also is responsible for compliance with all regulations
applicable to the mortgage service and products, including the maintenance of
requisite broker licenses, registration, approvals and
 
                                       50
 
exemptions. The initial term of the agreement began on August 1, 1998, expires
one year from the commencement of the priceline.com mortgage service and renews
automatically thereafter. The agreement may be terminated by either party after
the initial term expires, or immediately in the event that the other party
materially breaches the agreement or becomes subject to a bankruptcy proceeding.
 
    HOTEL ALLIANCES
 
    In connection with priceline.com's hotel service, priceline.com has entered
into letter agreements with eight hotel chains. The agreements generally provide
for the hotels to supply priceline.com with competitive net rates for hotel
properties included in the priceline.com service. Hotels must be of 2-star
quality or higher, with priceline.com to make the final quality determination.
These letter agreements do not require the hotels to provide any minimum level
of inventory. In most cases, the agreements are cancellable by either party at
any time.
 
    ADAPTIVE MARKETING ALLIANCES
 
   
    Priceline.com's principal adaptive marketing promotion offers consumers the
ability to apply for a credit card issued by Capital One while submitting offers
through priceline.com. In connection with this promotion, priceline.com is paid
a fee by Capital One for each qualifying credit card application. On March 3,
1999, Capital One exercised its contractual option to cease accepting credit
card applications through priceline.com effective May 1, 1999 unless
priceline.com enters into a new agreement with them on revised terms which they
have offered to priceline.com. Priceline.com has entered into an agreement in
principle with First USA Bank, a leading national credit card issuer, under
which First USA would replace Capital One as priceline.com's strategic partner
in its credit card adaptive marketing program. Under the First USA adaptive
marketing program, priceline.com would enable its customers to increase the
amount of their offers by a specified amount by applying online for a First USA
credit card and would offer other promotions linked to the First USA customer
acquisition program. Priceline.com would earn fees in a variety of ways
including (1) upon the acceptance by First USA of credit card applications
submitted through the priceline.com service, up to a specified maximum amount of
five million accepted credit card applications, subject to reduction under
certain circumstances by First USA, (2) upon the activation of credit card
accounts acquired for First USA through the priceline.com service and based upon
the use of such accounts (3) for transfers of balances from other credit cards
to First USA credit cards through the priceline.com service. The First USA
agreement would have a term of five years, subject to certain termination and
repricing provisions.
    
 
    While priceline.com expects to enter into a definitive agreement with First
USA, there can be no assurance that such an agreement will in fact be executed,
or that the terms of any such agreement will be substantially the same as, or
similar to, those contemplated in the agreement in principle. Moreover,
priceline.com can give no assurance that a new adaptive marketing credit card
program with First USA or any other credit card issuer will be established by
the expiration of the Capital One program or that it will provide priceline.com
with financial benefits comparable to those provided under the Capital One
program. Capital One currently pays a fee for each qualifying credit card
application submitted over the priceline.com service. The fee structure of the
First USA program is based on the factors described above which may or may not
result in revenues comparable to those under the Capital One program. If
priceline.com fails to secure a new adaptive marketing program with First USA or
another credit card issuer, its revenues and gross margin are likely to decrease
significantly, which could materially and adversely affect its business and
prospects.
 
    Priceline.com also has a co-marketing agreement with E*TRADE to establish an
adaptive marketing program under which E*TRADE will compensate priceline.com for
offering priceline.com customers the opportunity to open an account with E*TRADE
while visiting or making an offer on the priceline.com Web site. As the first
phase of this program, priceline.com and E*TRADE have established the Customer
Affinity Share Purchase Program under which customers of priceline.com who also
are account holders at
 
                                       51
 
E*TRADE will receive priority in the allocation by E*TRADE of priceline.com
shares in this offering, subject to a maximum allocation of 100 shares per
customer account and limited by the total number of shares made available to
E*TRADE. The parties intend to expand the adaptive marketing program to apply to
offers by customers for products and services over the priceline.com service.
However, under the terms of the co-marketing agreement, E*TRADE will be
permitted to terminate the expanded program at any time. Under the co-marketing
agreement, E*TRADE has agreed to pay priceline.com a daily fee, which increases
in increments based on the number of funded account applications submitted to
E*TRADE by priceline.com customers. E*TRADE also has agreed to pay priceline.com
an additional fee in certain circumstances for each successful priceline.com
transaction in which the customer participates in the E*TRADE adaptive marketing
program.
 
    Priceline.com also offers an adaptive marketing promotion for magazine
subscriptions pursuant to a revenue sharing agreement with NewSub Services,
Inc., a magazine subscription agent that is an affiliate of priceline.com's
Founder and Vice Chairman, Mr. Jay S. Walker. Under the agreement with NewSub
Services, priceline.com shares in a percentage of the revenues generated upon
the conversion of priceline.com generated subscriptions to annual subscriptions
after a six month free trial period.
 
COMPETITION
 
    Priceline.com competes with both online and traditional sellers of the
products and services offered on priceline.com. The market for selling products
and services over the Internet is new, rapidly evolving and intensely
competitive. Current and new competitors can launch new sites at a relatively
low cost. In addition, the traditional retail industry for the products and
services priceline.com offers is intensely competitive.
 
    Priceline.com currently or potentially competes with a variety of companies
with respect to each product or service it offers. With respect to travel
products, these competitors include:
 
    - Internet travel agents such as Travelocity, Preview Travel and Microsoft's
      Expedia.com;
 
    - traditional travel agencies;
 
    - consolidators and wholesalers of airline tickets and other travel
      products;
 
    - individual airlines, hotels, rental car companies, cruise operators and
      other travel service providers; and
 
    - operators of travel industry reservation databases such as Worldspan and
      Sabre.
 
Priceline.com's current or potential competitors with respect to new automobiles
include traditional and online auto dealers, including newly developing auto
super stores such as Auto Nation, Auto-by-Tel and Microsoft's CarPoint. With
respect to financial service products, priceline.com's competitors include:
 
    - banks and other financial institutions;
 
    - online and traditional mortgage and insurance brokers, including Quicken
      Mortgage, E-Loan and Home Shark; and
 
    - insurance companies.
 
While priceline.com faces competition from all of these current or potential
competitors, its business and financial position would be particularly at risk
if the airlines chose to establish their own buyer-driven commerce system to
sell excess inventory.
 
    Priceline.com potentially faces competition from a number of large Internet
companies and services that have expertise in developing online commerce and in
facilitating Internet traffic, including America Online, Microsoft and Yahoo!,
who could choose to compete with priceline.com either directly or indirectly

recognition, technical expertise and experience in Internet commerce could also
seek to compete with priceline.com. Competition from these and other sources
could have a material adverse effect on priceline.com's business, results of
operations and financial condition.
 
    Priceline.com believes that the principal competitive factors in its markets
are brand recognition, price, Web site accessibility, ability to fulfill offers,
customer service, reliability of delivery, ease of use, and technical expertise
and capabilities. Many of priceline.com's current and potential competitors,
including Internet directories and search engines and large traditional
retailers, have longer operating histories, larger customer bases, greater brand
recognition and significantly greater financial, marketing, technical and other
resources than priceline.com. Some of these competitors may be able to secure
products and services on more favorable terms than priceline.com. In addition,
many of these competitors may be able to devote significantly greater resources
to:
 
    - marketing and promotional campaigns;
 
    - attracting traffic to their Web sites;
 
    - attracting and retaining key employees; and
 
    - Web site and systems development.
 
Increased competition could result in reduced operating margins and loss of
market share and could damage priceline.com's brand. There can be no assurance
that priceline.com will be able to compete successfully against current and
future competitors or that competition will not have a material adverse effect
on priceline.com's business, results of operations and financial condition.
 
OPERATIONS AND TECHNOLOGY
 
    Priceline.com's business is supported by a state of the art systems
platform, which was designed with an emphasis on scalability, performance and
reliability. Priceline.com's core demand collection and offer processing systems
are proprietary to priceline.com. The software platform and architecture are
built on server-side Java, C++, and ISO standard SQL scripts integrated with an
Oracle relational database system. This internal platform was designed to
include open application protocol interfaces that can provide real-time
connectivity to vendors in the range of industries in which the priceline.com
operates. These include large global inventory systems, such as airline and
hotel reservation systems, for example, the Worldspan central reservation
systems; and financial service providers; as well as individual inventory
suppliers, such as auto dealers, individual hotels and hard goods merchants.
Priceline.com's Internet servers utilize Verisign digital certificates to help
it conduct secure communications and transactions.
 
    Priceline.com out-sources most of its call center and customer service
functions, and uses a real-time interactive voice response system with transfer
capabilities to its call centers and customer service centers in Stamford,
Connecticut; Columbus, Ohio; and Charlotte, North Carolina.
 
    Priceline.com's systems infrastructure, Web and database servers are hosted
at Exodus Communications, Inc. in Jersey City, New Jersey, which provides
communication lines from multiple providers including UUNet and AT&T, as well as
24-hour monitoring and engineering support. Exodus has its own generator and
multiple back-up systems in Jersey City. Priceline.com also maintains an
uninterruptible power supply system and generator and redundant servers at its
Stamford, Connecticut headquarters to provide service capability if the Exodus
site fails.
 
    While priceline.com primarily is an Internet business, it also offers phone
service through its toll-free number, 1-800-Priceline. This service allows
consumers who do not have access to a computer to phone in their orders. From
launch to December 31, 1998, priceline.com has received approximately 15% of its
airline ticket orders through its toll-free number. In addition, consumers who
choose not to transmit their credit card information via the Internet have the
option of submitting their credit card information through the phone service.
Priceline.com also uses its toll-free number to provide customer service.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
    Priceline.com holds a business process patent issued by the United States
Patent and Trademark Office which is directed to a unique buyer-driven commerce
system. While so-called business process patents are only now becoming widely
understood by the general business community, a decision by the Court of Appeals
for the Federal Circuit (the highest United States appellate court for
patent-related appeals below the United States Supreme Court), recently affirmed
the validity of patents covering software-implemented business processes. STATE
STREET BANK & TRUST CO. V. SIGNATURE FINANCIAL GROUP, INC. (July 1998).
 
    Priceline.com currently holds two issued United States patents, No.
5,794,207 and No. 5,797,127, as well as one allowed and eighteen pending United
States patent applications and one pending international patent application.
Priceline.com is in the process of filing at least three more patent
applications, with an ongoing program for identifying and protecting new
inventions. Priceline.com's core business method patent is directed to a unique
buyer-driven commerce system using a computer to collect credit card-backed or
other financial account-backed conditional purchase offers to present to
multiple sellers, receive one or more acceptances or fulfillments of these
offers, and use the credit card or other financial account to provide a payment
to one or more of the sellers. The pending patent applications are directed to
various operational features of the system, as well as to product-specific
enhancements.
 
    While priceline.com believes that its core buyer-driven commerce patent,
together with its pending patent applications, help to protect the priceline.com
business, there can be no assurance that (1) the core buyer-driven patent or any
other patent can be successfully defended against challenges by third parties;
(2) the pending patent applications will result in the issuance of patents; (3)
competitors or potential competitors of priceline.com will not devise new
methods of competing with the company that are not covered by priceline.com's
patent or patent applications; (4) because of variations in the application of
our business model to each of our products and services, our core buyer-driven
commerce patent may not be effective in preventing one or more third parties
from utilizing a copycat business model to offer the same product or service in
one or more categories; or (5) a third party will not have or obtain one or more
patents that prevent priceline.com from practicing features of its business or
will require priceline.com to pay for a license to use those features.
Priceline.com has been notified that a third party patent applicant has
challenged its core patent through an interference action in the United States
Patent and Trademark Office. See "-- Legal Proceedings." In addition,
priceline.com has learned of several Internet travel services that appear to use
customer-offer based transaction models.
 
    Priceline.com seeks to protect its copyrights, service marks, trademarks,
trade dress and trade secrets through a combination of laws and contractual
restrictions, such as confidentiality agreements. For example, priceline.com
attempts to register its trademarks and service marks in the United States and
internationally. However, effective trademark, service mark, copyright and trade
secret protection may not be available in every country in which priceline.com's
services are made available online. See "Risk Factors -- Our Success Depends on
Our Ability to Protect Our Intellectual Property." A third party has sued
priceline.com for, among other things, misappropriation of trade secrets. See
"Legal Proceedings."
 
    Priceline.com currently owns the Internet domain name "priceline.com."
Domain names generally are regulated by Internet regulatory bodies. The
relationship between regulations governing domain names and laws protecting
trademarks and similar proprietary rights is unclear. Priceline.com, therefore,
could be unable to prevent third parties from acquiring domain names that
infringe or otherwise decrease the value of its trademarks and other proprietary
rights. See "Risk Factors -- Our Success Depends on Our Ability to Protect Our
Intellectual Property."
 
GOVERNMENTAL REGULATION
 
    The products and services offered through the priceline.com service are
regulated by federal and state governments.
 
                                       54
 
    TRAVEL SERVICES
 
   
    Priceline.com is subject to the laws and regulations of a number of states
governing the offer and/or sale of travel services. For example, Priceline
Travel is registered as a "seller of travel" under the California Seller of
Travel Act and is a member of the Airline Reporting Corporation. Priceline.com
also will be making similar filings for registration and membership prior to
consummation of this offering. In addition, a number of state travel laws and
regulations require compliance with specific disclosure, bond and/or other
requirements. All travel registrations were previously held by Priceline Travel.
To the extent that such registrations could be transferred by merger,
priceline.com succeeded to all such registrations by merging with Priceline
Travel as of March 24, 1999. Priceline.com has obtained other required travel
related registrations.
    
 
    NEW CAR SALES
 
    A number of states have laws and regulations governing the registration and
conduct of automobile dealers and brokers. Such laws generally provide that any
person receiving direct or indirect compensation for selling automobiles or
brokering automobile transactions must register as an automobile broker or
dealer. Registration for automobile dealers/brokers may, among other things,
require the registrant to maintain a physical office in the applicable state, a
dealer lot zoned for automobile sales within the applicable state and/or a
franchise agreement with the manufacturers of the automobiles to be sold.
Priceline.com believes that it is not subject to such automobile dealer/broker
laws because priceline.com is a car buying service, and not a seller or broker
of automobiles, operating on behalf of customers and participating dealers.
 
    It is uncertain how automobile dealer and broker laws apply to the provision
of automobile selling services offered through the Internet. Priceline.com has
been orally advised by representatives of a number of states that, generally, no
enforcement action will be initiated against Internet companies for
non-compliance with such laws until clearer regulatory or legislative guidance
is provided.
 
    It is possible, however, that state regulatory bodies could take the view
that priceline.com is subject to automobile broker and dealer laws, in which
case they could attempt to require priceline.com to register as an automobile
broker/dealer in the applicable states. Given the nature of priceline.com's
business, any requirement to register under such laws could severely interfere
with the conduct of its business.
 
    HOME MORTGAGES
 
    Most states have laws and regulations governing the registration or
licensing and conduct of persons providing mortgage brokerage services. Such
laws and regulations also typically require certain consumer protection
disclosures, loan solicitation procedures and a variety of other practices
throughout the various stages of the mortgage solicitation, application and
approval process.
 
    In addition to state law, mortgage brokerage services are heavily regulated
by federal law. For example, the Real Estate Settlement Procedures Act,
prohibits the payment and receipt of mortgage loan referral fees. The act,
however, does permit persons to be compensated for the fair market value of non-
referral services actually rendered.
 
    Priceline.com introduced its home mortgage service in January 1999.
LendingTree serves as the mortgage broker and provides all mortgage brokerage
services. Priceline.com provides and is responsible for maintaining the home
mortgage service on its Web site and develops and purchases all advertising.
LendingTree will compensate priceline.com for the fair market value of its
non-referral services. Priceline.com believes that offering the priceline.com
home mortgage service does not require our registration under or compliance with
the mortgage or similar brokerage laws of any jurisdiction. However, it is
possible that one or more regulatory authorities could seek to enforce existing
laws, or otherwise enact new legislation, requiring priceline.com's registration
and compliance and could scrutinize the compensation arrangement between
LendingTree and priceline.com under Real Estate Settlement Procedures Act or
 
                                       55
 
other federal or state laws. Such action could severely interfere with the
conduct of the priceline.com business.
 
    LendingTree provides the mortgage brokerage services offered through the
priceline.com home mortgage service on priceline.com's Web site and is
responsible for maintaining the necessary and appropriate state registrations
and licenses associated with LendingTree's provision of those mortgage brokerage
services. If a federal or state regulatory authority, or an aggrieved customer,
should in the future claim that LendingTree has failed to comply fully with
applicable federal or state law requirements pertaining to LendingTree's
provision of mortgage brokerage services, the priceline.com home mortgage
service could be materially and adversely affected and priceline.com may be
unable to continue to make its home mortgage services Web site available, either
to residents of affected state(s) or on a national basis.
 
    CONSUMER PROTECTION AND RELATED LAWS
 
    All of priceline.com's services are subject to federal and state consumer
protection laws and regulations prohibiting unfair and deceptive trade
practices. Priceline.com is also subject to related "plain language" statutes in
place in many jurisdictions, which require the use of simple, easy to read,
terms and conditions in contracts with consumers.
 
    Although there are very few laws and regulations directly applicable to the
protection of consumers in an online environment, it is possible that
legislation will be enacted in this area and could cover such topics as
permissible online content and user privacy, including the collection, use,
retention and transmission of personal information provided by an online user.
Furthermore, the growth and demand for online commerce could result in more
stringent consumer protection laws that impose additional compliance burdens on
online companies. Such consumer protection laws could result in substantial
compliance costs and interfere with the conduct and growth of the priceline.com
business.
 
    BUSINESS QUALIFICATION LAWS
 
    Because priceline.com's service is available over the Internet in multiple
states, and because it sells to numerous consumers resident in such states, such
jurisdictions may claim that priceline.com is required to qualify to do business
as a foreign corporation in each such state. Priceline.com is qualified to do
business in a limited number of states, and failure by priceline.com to qualify
as a foreign corporation in a jurisdiction where it is required to do so could
subject priceline.com to taxes and penalties for the failure to so qualify and
limit its ability to conduct litigation in such states.
 
    INTERNATIONAL EXPANSION
 
    Priceline.com intends to explore opportunities for expanding the
priceline.com business into international markets. It is possible, however, that
the priceline.com demand collection system will not be readily adaptable to
regulatory environments of certain foreign jurisdictions. In addition, there are
various other risks associated with international expansion. They include
language barriers, unexpected changes in regulatory requirements, trade
barriers, problems in staffing and operating foreign operations, changes in
currency exchange rates, difficulties in enforcing contracts and other legal
rights, economic and political instability and problems in collection.
 
LEGAL PROCEEDINGS
 
    On January 6, 1999, priceline.com received notice that a third party patent
applicant and patent attorney, Thomas G. Woolston, purportedly had filed in
December 1998 with the United States Patent and Trademark Office a request to
declare an "interference" between a patent application filed by Woolston
describing an electronic market for used and collectible goods and
priceline.com's core buyer-driven commerce patent. Priceline.com has received a
copy of a Petition for Interference from Woolston, the named inventor in at
least three United States Patent applications titled "Consignment Nodes," one of
which has issued as a patent (U.S. Patent Number: 5,845,265). Priceline.com
currently is awaiting
 
                                       56
 
information from the Patent Office regarding whether it will initiate an
interference proceeding concerning Woolston's patent application and
priceline.com's core buyer-driven commerce patent. An interference is an
administrative proceeding instituted in the Patent Office to determine questions
of patentability and priority of invention between two or more parties claiming
the same patentable invention. There is no statutory period within which the
Patent Office must act on an interference request. If an interference is
declared and proceeds through a final hearing in the Patent Office, a final
judgment is made by the Patent Office as to inventorship. Following such final
judgment, appeals could be made in Federal court. While there can be no
certainty as to time periods, interference proceedings typically take years to
resolve.
 
    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from the
priceline.com core buyer-driven commerce patent. In order to make this showing,
he would have to prove, among other things, that he invented the subject matter
of the priceline.com claims before the inventors of the priceline.com patent. If
the Patent Office were to find that Woolston's patent application supported the
copied priceline.com claims, it would resolve the interference by awarding
inventorship to the party with the earliest proven date of invention. Woolston
recently announced an agreement to license his issued patent and pending patent
applications to the owner of an Internet travel service that, according to such
announcement, commenced on-line operations in the fourth quarter of 1998 and
purports to compete with priceline.com.
 
   
    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While Woolston claims to have an earlier
invention date by a period of approximately sixteen months, the final decision
as to priority of invention would be made by the Patent Office after considering
facts provided by each party during the interference proceeding. If an
interference is declared and thereafter resolved in favor of Woolston, such
resolution could result in an award of some or all of the disputed patent claims
to Woolston. If, following such award, Woolston were successful in a patent
infringement action against priceline.com, including prevailing over all
defenses available to priceline.com such as those of non-infringement and
invalidity, this could require priceline.com to obtain licenses from Woolston at
a cost which could significantly adversely affect priceline.com's business. If
Woolston prevailed in both an interference and an infringement action, then
priceline.com could be enjoined from conducting business through the
priceline.com service to the extent covered by the patent claims awarded to
Woolston. In addition, defense of the interference action may be expensive and
may divert management attention away from priceline.com's business.
    
 
    On January 19, 1999, a lawsuit was filed in the United States District Court
for the Northern District of California by Marketel International, Inc., a
California corporation, under the caption MARKETEL INTERNATIONAL INC. V.
PRICELINE.COM ET. AL., No. C-99-1061 (N.D. CA 1999), against priceline.com,
Priceline Travel, Walker Asset Management, Walker Digital, Mr. Jay S. Walker,
priceline.com's Founder and Vice Chairman, and Mr. Andre Jaeckle, an individual
who made a $1 million loan to priceline.com bearing interest at a rate of 6% per
year, and in connection therewith, received warrants, which have subsequently
been fully exercised, to purchase 62,500 shares of our common stock. On February
22, 1999, Marketel filed an amended and supplemental complaint. The amended
complaint filed by Marketel, which joins as defendants Mr. Timothy G. Brier, our
Executive Vice President, Travel, Mr. Bruce Schneier, an individual and
consultant to Walker Digital, and Mr. James Jorasch, an individual and employee
of Walker Digital, alleges causes of action for, among other things,
misappropriation of trade secrets, breach of contract, conversion, breach of
confidential relationship, copyright infringement, fraud, unfair competition,
and false advertising, and seeks injunctive relief and damages in an unspecified
amount. In its amended complaint, Marketel alleges, among other things, that the
defendants conspired to misappropriate Marketel's business model, which it
describes as a buyer-driven electronic marketplace for travel services and its
appurtenant techniques, market research, forms, plans and processes, and which
an executive of
 
                                       57
 
Marketel allegedly provided to Messrs. Walker and Jaeckle in confidence
approximately ten years ago. The amended complaint also alleges that three
former Marketel employees are the actual sole inventors or co-inventors of US
patent No. 5794207, which was issued on August 11, 1998 with Jay S. Walker,
Bruce Schneier and James Jorasch listed as the inventors and which patent has
been assigned to priceline.com. Marketel asks that the patent's inventorship be
corrected accordingly.
 
    Based upon publicly available information, priceline.com believes that
Marketel's fax and fee-based business was launched in 1991 and ceased operations
seven months later. Priceline.com's Internet-based model was independently
developed by Walker Digital and priceline.com, and practiced by priceline.com
starting in 1998. Based on publicly available information and Marketel's
complaint, priceline.com understands that Marketel operated a fax-based travel
information service which offered consumers, travel agents and/or consolidators
the opportunity to purchase specially printed forms. These forms, when
accompanied by an additional non-refundable fee, allowed prospective ticket
buyers to fax to Marketel credit-card guaranteed bids for airline travel at a
bid price specified by the buyer. Priceline.com believes that Marketel has not
engaged in any regular commercial activities since ceasing operations in 1992.
Based upon publicly available information, Marketel reactivated its active
status as a corporation by satisfying its back-due tax obligations to the State
of California shortly after the filing of its complaint.
 
    On February 5, and February 10, 1999, the defendants filed their answer and
amended answer, respectively, to the amended complaint, in which they denied the
material allegations of liability in the complaint. Priceline.com and all other
defendants strongly dispute the material legal and factual allegations contained
in Marketel's amended complaint and believe that the amended complaint is
without merit. Priceline.com intends to defend vigorously against the action.
Defending the law suit may involve significant expense and, due to the inherent
uncertainties of litigation, there can be no certainty as to the ultimate
outcome. Pursuant to the terms of the indemnification obligations contained in
the Purchaser and Intercompany Agreement with Walker Digital, Walker Digital has
agreed to indemnify priceline.com for damages, liability and legal expenses
incurred in connection with the Marketel litigation.
 
    From time to time priceline.com has been and expects to continue to be
subject to legal proceedings and claims in the ordinary course of business,
including claims of alleged infringement of third party intellectual property
rights by the company. Such claims, even if not meritorious, could result in the
expenditure of significant financial and managerial resources.
 
EMPLOYEES
 
   
    Currently, priceline.com has 194 full-time employees. In addition, through
an Intercompany Agreement with Walker Digital Corporation, priceline.com
receives a variety of services, including research and development, patent and
other intellectual property services and technical support. Priceline.com also
employs independent contractors to support its customer service and system
support functions. See "Certain Transactions."
    
 
    Priceline.com has never had a work stoppage and its employees are not
represented by any collective bargaining unit. It considers its relations with
its employees to be good. Priceline.com's future success will depend, in part,
on its ability to continue to attract, integrate, retain and motivate highly
qualified technical and managerial personnel, for whom competition is intense.
 
FACILITIES
 
   
    Priceline.com's executive, administrative and operating offices are located
in approximately 35,000 square feet of leased office space located in Stamford,
Connecticut. Priceline.com is subleasing this office space from Walker Digital
on a month-to-month basis. Priceline.com also has guaranteed Walker Digital's
obligations under a lease of office space in New York City that is used by both
companies. Priceline.com anticipates that it will require additional space
within the next 12 months to accommodate its anticipated growth and that
suitable office space will be available on commercially reasonable terms.

STOCK BASED PLANS
 
   
    Pursuant to the priceline.com Incorporated 1997 Omnibus Plan, priceline.com
has granted awards of options to certain officers, other employees, consultants
and directors of priceline.com. The maximum number of shares of common stock
reserved for the grant or settlement of awards under the 1997 Omnibus Plan is
23,875,000, subject to adjustment as provided therein. Of such number,
23,800,875 options covering shares of common stock were outstanding under the
1997 Omnibus Plan as of March 17, 1999. In February 1999, priceline.com
established the priceline.com Incorporated 1999 Omnibus Plan, pursuant to which
awards will be made to certain officers, other employees, consultants and
directors of priceline.com from time to time following the consummation of this
offering. The maximum number of shares of common stock reserved for the grant or
settlement of awards under the 1999 Omnibus Plan is 9,375,000, subject to
adjustment.
    
 
    Set forth below is a description of the provisions of the 1999 Omnibus Plan
and the provisions of the 1997 Omnibus Plan. The description is only a summary
and is qualified in its entirety by the provisions of such plans. Terms not
defined herein have the meanings given to such terms in the respective plans.
 
PRICELINE.COM INCORPORATED 1997 OMNIBUS PLAN
 
    The 1997 Omnibus Plan was ratified and approved by the board of directors
and stockholders of priceline.com and by the Board of Managers and the members
of priceline.com LLC in 1997. The 1997 Omnibus Plan is intended to promote the
long term financial interests and growth of priceline.com by providing
employees, officers, directors and consultants of priceline.com with appropriate
incentives and rewards to enter into and continue in the employ of, or their
relationship with, the company and to acquire a proprietary interest in the
long-term success of the company; and to reward the performance of individual
officers, other employees, consultants and directors in fulfilling their
responsibilities for long-range achievements.
 
    GENERAL
 
    The 1997 Omnibus Plan provides for the granting of awards to such officers,
other employees, consultants and directors of priceline.com and its affiliates
as the compensation committee, which is the committee of the board appointed to
administer the 1997 Omnibus Plan, may select from time to time. Awards under the
1997 Omnibus Plan may be made in the form of options to acquire priceline.com
common stock. Some of the options granted under the 1997 Omnibus Plan may
qualify as "incentive stock options;" as defined in the Internal Revenue Code of
1986, generally referred to as the "Code," and some of the options granted under
the 1997 Omnibus Plan will not qualify as incentive stock options. Such options
are generally referred to as "non-qualified stock options." Awards under the
1997 Omnibus Plan may also be made in the form of appreciation rights with
respect to common stock, which appreciation rights may be granted in tandem with
other awards or may be granted independent of other awards, or may be made in
the form of restricted stock, phantom stock, stock bonuses or other awards.
 
    If any shares subject to an award are forfeited, cancelled, exchanged or
surrendered or if an award otherwise terminates or expires without a
distribution of shares to the holder of such award, the shares of common stock
with respect to such award will, to the extent of any such forfeiture,
cancellation, exchange, surrender, termination or expiration, again be available
for awards under the 1997 Omnibus Plan.
 
    In the event that the compensation committee determines that any dividend or
other distribution (whether in the form of cash, common stock, or other
property), recapitalization, stock split, reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase, or share exchange, or other
similar corporate transaction or event, affects the common stock such that an
adjustment is appropriate in order to prevent dilution or enlargement of the
rights of holders of awards under the 1997 Omnibus Plan, then the compensation
committee will make such equitable changes or adjustments as it deems necessary
or appropriate to any or all of (1) the number and kind of shares of common
stock or other property (including cash) that may thereafter be issued in
connection with awards; (2) the number and kind of
 
                                       64
 
shares of common stock or other property (including cash) issued or issuable in
respect of outstanding awards; (3) the exercise price, grant price, or purchase
price relating to any award; and (4) the maximum number of shares of common
stock subject to outstanding awards that may be awarded to any employee during
any priceline.com tax year; provided that, with respect to incentive stock
options, such adjustment shall be made in accordance with the applicable
provisions of the Code.
 
    ADMINISTRATION
 
    The 1997 Omnibus Plan will be administered by the compensation committee.
The compensation committee has the authority in its sole discretion, subject to
and not inconsistent with the express provisions of the 1997 Omnibus Plan, to
administer the 1997 Omnibus Plan and to exercise all the powers and authorities
either specifically granted to it under, or necessary or advisable in the
administration of, the 1997 Omnibus Plan, including, without limitation, the
authority to grant awards; to determine the persons to whom and the time or
times at which awards shall be granted; to determine the type and number of
awards to be granted, the number of shares of common stock to which an award may
relate and the terms, conditions, restrictions and performance goals relating to
any award; to determine whether, to what extent, and under what circumstances an
award may be settled, canceled, forfeited, exchanged, or surrendered; to make
adjustments in the performance goals in recognition of unusual or non-recurring
events affecting priceline.com or the financial statements of priceline.com, to
the extent not inconsistent with Section 162(m) of the Code, if applicable, or
in response to changes in applicable laws, regulations, or accounting
principles; to construe and interpret the 1997 Omnibus Plan and any award; to
prescribe, amend and rescind rules and regulations relating to the 1997 Omnibus
Plan; to determine the terms and provisions of agreements evidencing awards; and
to make all other determinations deemed necessary or advisable for the
administration of the 1997 Omnibus Plan.
 
    The compensation committee may, in its absolute discretion, without
amendment to the 1997 Omnibus Plan, (a) accelerate the date on which any option
or stand-alone appreciation right granted under the 1997 Omnibus Plan becomes
exercisable, waive or amend the operation of provisions respecting exercise
after termination of employment or otherwise adjust any of the terms of such
option or stand-alone appreciation right, (b) accelerate the vesting or waive
any condition imposed with respect to any restricted stock, phantom stock or
other awards and (c) otherwise adjust any of the terms applicable to any award.
 
    AWARDS UNDER THE 1997 OMNIBUS PLAN
 
    STOCK OPTIONS; STOCK APPRECIATION RIGHTS
 
    Unless otherwise determined by the compensation committee, options granted
pursuant to the 1997 Omnibus Plan will become exercisable ratably over three
years commencing on the first anniversary of the date of grant, but in no event
may an option be exercised more than 10 years following the date of its grant.
The "option exercise price," which is the purchase price per share payable upon
the exercise of an option, will be established by the compensation committee;
PROVIDED, HOWEVER, that incentive stock options may not have an exercise price
less than the fair market value of a share of common stock on the date of grant.
The option exercise price is payable by any one of the following methods or a
combination thereof, to the extent permitted by the compensation committee: (1)
in cash or by personal check, certified check, bank cashier's check or wire
transfer; (2) subject to the approval of the compensation committee, in common
stock owned by the participant for at least six months prior to the date of
exercise and valued at their fair market value on the effective date of such
exercise; or (3) subject to the approval of the compensation committee, by such
other provision as the compensation committee may from time to time authorize.
 
    The compensation committee also has the authority to specify, at the time of
grant or, with respect to non-qualified stock options at or after the time of
grant, that a participant shall be granted a new non-qualified stock option,
otherwise known as a "reload option," for a number of shares of common stock
equal to the number of shares of common stock surrendered by the participant
upon exercise of all or a part of an option in the manner described above,
subject to the availability of common stock under the
 
                                       65
 
1997 Omnibus Plan at the time of such exercise; PROVIDED, HOWEVER, that no
reload option shall be granted to a non-employee director. Reload options shall
be subject to such conditions as may be specified by the compensation committee
in its discretion, subject to the terms of the 1997 Omnibus Plan.
 
    Appreciation rights with respect to priceline.com's common stock may be
granted alone or in tandem with options. An appreciation right is a right to be
paid an amount in cash for each share of common stock subject to the
appreciation right equal to the excess of the fair market value of a share of
common stock on the date the appreciation right is exercised over either the
fair market value of a share of common stock on the date of grant, in case of a
stand-alone appreciation right, or the exercise price of the related stock
option, in case of a tandem appreciation right.
 
    RESTRICTED STOCK; PHANTOM STOCK
 
    A restricted stock award is an award of common stock and a phantom stock
award is an award of the right to receive cash or common stock at a future date,
in each case, that is subject to such restrictions on transferability and other
restrictions, if any, as the compensation committee may impose at the date of
grant or thereafter, which restrictions may lapse separately or in combination
at such times, under such circumstances, including, without limitation, a
specified period of employment or the satisfaction of pre-established
performance goals, when granted to executive officers, in such installments, or
otherwise, as the compensation committee may determine. The compensation
committee may grant such restricted stock or phantom stock to such persons, in
such amounts, and subject to such terms and conditions as the compensation
committee may determine in its discretion; PROVIDED, HOWEVER, that shares of
restricted stock and phantom stock granted to executive officers may vest upon
the attainment of performance goals pre-established by the compensation
committee, based on one or more of the following criteria: return on total owner
equity; earnings per share; pre-tax income or after-tax income; revenue; return
on assets; increases in EBITDA; or such other criteria as the stockholders of
priceline.com may approve.
 
    OTHER AWARDS
 
    Upon a determination by the compensation committee, an executive officer may
receive awards of shares of common stock. In addition, other awards valued in
whole or in part by reference to, or otherwise based on, common stock may be
granted either alone or in addition to other awards under the 1997 Omnibus Plan.
Subject to the provisions of the 1997 Omnibus Plan, the compensation committee
will have the sole and complete authority to determine the persons to whom and
the time or times at which such other awards will be granted, the number of
shares of common stock to be granted pursuant to such other awards and all other
conditions of such other awards.
 
    AMENDMENT; TERMINATION
 
    The board of directors or the compensation committee may suspend, revise,
terminate or amend the 1997 Omnibus Plan at any time; PROVIDED, HOWEVER, that
(1) stockholder approval will be obtained if and to the extent required under
Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended,
which is generally referred to as the "Exchange Act," or if and to the extent
the board determines that such approval is required for purposes of satisfying
Section 162(m) or Section 422 of the Code and (2) no such suspension, revision,
termination or amendment may, without the consent of a participant, reduce the
participant's rights under any outstanding award.
 
    NEW 1997 OMNIBUS PLAN BENEFITS
 
    Prior to the consummation of the offering, priceline.com intends to grant
additional awards under the 1997 Omnibus Plan up to the maximum number of shares
currently reserved for the grant or settlement of awards under the 1997 Omnibus
Plan. See "Option Grants in Last Fiscal Year" for the name, position and grant
information for 1997 Omnibus Plan participants who were granted awards
thereunder during fiscal year 1998.
 
                                       66
 
    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion is a brief summary of the principal United States
federal income tax consequences under current federal income tax laws relating
to awards under the 1997 Omnibus Plan. This summary is not intended to be
exhaustive and, among other things, does not describe state, local or foreign
income and other tax consequences.
 
    NON-QUALIFIED STOCK OPTIONS
 
    An optionee will not recognize any taxable income upon the grant of a
non-qualified stock option. Priceline.com will not be entitled to a tax
deduction with respect to the grant of a non-qualified stock option. Upon
exercise of a non-qualified stock option, the excess of the fair market value of
the common stock on the exercise date over the option exercise price will be
taxable as compensation income to the optionee and will be subject to applicable
withholding taxes. Priceline.com will generally be entitled to a tax deduction
at such time in the amount of such compensation income. The optionee's tax basis
for the common stock received pursuant to the exercise of a non-qualified stock
option will equal the sum of the compensation income recognized and the exercise
price.
 
    In the event of a sale of common stock received upon the exercise of a
non-qualified stock option, any appreciation or depreciation after the exercise
date generally will be taxed as capital gain or loss.
 
    INCENTIVE STOCK OPTIONS
 
    An optionee will not recognize any taxable income at the time of grant or
timely exercise of an incentive stock option and priceline.com will not be
entitled to a tax deduction with respect to such grant or exercise. Exercise of
an incentive stock option may, however, give rise to taxable compensation income
subject to applicable withholding taxes, and a tax deduction to priceline.com,
if the incentive stock option is not exercised on a timely basis (generally,
while the optionee is employed by priceline.com or within 90 days after
termination of employment) or if the optionee subsequently engages in a
"disqualifying disposition," as described below.
 
    A sale or exchange by an optionee of shares acquired upon the exercise of an
incentive stock option more than one year after the transfer of the shares to
such optionee and more than two years after the date of grant of the incentive
stock option will result in any difference between the net sale proceeds and the
exercise price being treated as long-term capital gain or loss to the optionee.
If such sale or exchange takes place within two years after the date of grant of
the incentive stock option or within one year from the date of transfer of the
incentive stock option shares to the optionee, such sale or exchange will
generally constitute a "disqualifying disposition" of such shares that will have
the following results: any excess of (x) the lesser of (1) the fair market value
of the shares at the time of exercise of the incentive stock option and (2) the
amount realized on such disqualifying disposition of the shares over (y) the
option exercise price of such shares, will be ordinary income to the optionee,
subject to applicable withholding taxes, and priceline.com will be entitled to a
tax deduction in the amount of such income. Any further gain or loss after the
date of exercise generally will qualify as capital gain or loss and will not
result in any deduction by priceline.com.
 
    APPRECIATION RIGHTS
 
    The grant of appreciation rights has no federal income tax consequences at
the time of grant. Upon the exercise of appreciation rights, the amount received
is generally taxable as ordinary income, and priceline.com is entitled to a
corresponding deduction.
 
    RESTRICTED STOCK
 
    A grantee will not recognize any income upon the receipt of restricted stock
unless the holder elects under Section 83(b) of the Code, within thirty days of
such receipt, to recognize ordinary income in an amount equal to the fair market
value of the restricted stock at the time of receipt, less any amount paid for
the shares. If the election is made, the holder will not be allowed a deduction
for amounts subsequently

required to be returned to priceline.com. If the election is not made, the
holder will generally recognize ordinary income, on the date that the
restrictions to which the restricted stock are subject are removed, in an amount
equal to the fair market value of such shares on such date, less any amount paid
for the shares. At the time the holder recognizes ordinary income, priceline.com
generally will be entitled to a deduction in the same amount.
 
    Generally, upon a sale or other disposition of restricted stock with respect
to which the holder has recognized ordinary income, for example, if a Section
83(b) election was previously made or the restrictions were previously removed,
the holder will recognize capital gain or loss in an amount equal to the
difference between the amount realized on such sale or other disposition and the
holder's basis in such shares.
 
    PHANTOM STOCK
 
    The grant of phantom stock has no federal income tax consequences at the
time of grant. Upon the receipt of payment, the amount received is generally
taxable as ordinary income, and priceline.com is entitled to a corresponding
deduction.
 
    OTHER TYPES OF AWARDS
 
    The grant of any other stock-based award generally will not result in income
for the grantee or in a tax deduction for priceline.com. Upon the settlement of
such an award, the grantee will recognize ordinary income equal to the aggregate
value of the payment received, and priceline.com generally will be entitled to a
tax deduction in the same amount.
 
PRICELINE.COM INCORPORATED 1999 OMNIBUS PLAN
 
    In February 1999, priceline.com established the 1999 Omnibus Plan. The 1999
Omnibus Plan is intended to promote the long-term financial interests and growth
of priceline.com by providing employees of priceline.com with appropriate
incentives and rewards to encourage them to enter into and continue in the
employ of the company and to acquire a proprietary interest in the long-term
success of the company; and to reward the performance of individual officers,
other employees, consultants and directors in fulfilling their responsibilities
for long-range achievements.
 
    GENERAL
 
    The 1999 Omnibus Plan provides for the granting of awards to such officers,
other employees, consultants and directors of priceline.com and its affiliates
as the compensation committee, which is the committee of the board of directors
appointed to administer the Plan may select from time to time. Awards under the
1999 Omnibus Plan may be made in the form of incentive stock options,
non-qualified stock options, restricted stock or other awards.
 
    The maximum number of shares of common stock reserved for the grant or
settlement of awards under the 1999 Omnibus Plan is 9,375,000 subject to
adjustment as provided in the 1999 Omnibus Plan. The maximum number of shares of
common stock that may be awarded in respect of options, restricted stock and
other awards to a single individual in any given year may not exceed 9,375,000,
3,125,000 and 6,250,000, respectively, which amounts are subject to adjustment
as described below. Awards (either as options, restricted stock or other awards)
will be made in a manner consistent with Section 162(m) of the Code. Shares of
common stock acquired upon the exercise or settlement of awards may, in whole or
in part, be authorized but unissued shares or shares that shall have been or may
be reacquired by priceline.com in the open market, in private transactions or
otherwise. If any shares subject to an award are forfeited, cancelled, exchanged
or surrendered or if an award otherwise terminates or expires without a
distribution of shares to the holder of such award, the shares of common stock
with respect to such award will, to the extent of any such forfeiture,
cancellation, exchange, surrender, termination or expiration, again be available
for awards under the 1999 Omnibus Plan.
 
                                       68
 
    Except as provided in an agreement evidencing the grant of an award, in the
event that the compensation committee determines that any dividend or other
distribution (whether in the form of cash, common stock, or other property),
recapitalization, stock split, reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase, or share exchange, or other
similar corporate transaction or event, affects the common stock such that an
adjustment is appropriate in order to prevent dilution or enlargement of the
rights of holders of awards under the 1999 Omnibus Plan, then the compensation
committee will make such equitable changes or adjustments as it deems necessary
or appropriate to any or all of (1) the number and kind of shares of common
stock or other property (including cash) that may thereafter be issued in
connection with awards, (2) the number and kind of shares of common stock or
other property, including cash, issued or issuable in respect of outstanding
awards, (3) the exercise price, grant price, or purchase price relating to any
award; provided that, with respect to incentive stock options, such adjustment
shall be made in accordance with Section 424(h) of the Code, (4) the performance
criteria with respect to an award and (5) the individual limitations applicable
to awards.
 
    ADMINISTRATION
 
    The 1999 Omnibus Plan is administered by the compensation committee, the
composition of which will at all times satisfy the provisions of Section 162(m)
of the Code and Rule 16b-3 promulgated under the Exchange Act. The compensation
committee has the authority, in its sole discretion, subject to and not
inconsistent with the express provisions of the 1999 Omnibus Plan, to
administer, and to exercise all the powers and authorities either specifically
granted to it under, the 1999 Omnibus Plan or necessary or advisable in the
administration of the 1999 Omnibus Plan, including, without limitation, the
authority to grant awards; to determine the persons to whom and the time or
times at which awards shall be granted; to determine the type and number of
awards to be granted, the number of shares of common stock to which an award may
relate and the terms, conditions, restrictions and performance goals relating to
any award; to determine whether, to what extent, and under what circumstances an
award may be settled, canceled, forfeited, exchanged, or surrendered; to make
adjustments in the performance goals in recognition of unusual or non-recurring
events affecting priceline.com or the financial statements of priceline.com, to
the extent not inconsistent with Section 162(m) of the Code, if applicable, or
in response to changes in applicable laws, regulations, or accounting
principles; to construe and interpret the 1999 Omnibus Plan and any award; to
prescribe, amend and rescind rules and regulations relating to the 1999 Omnibus
Plan; to determine the terms and provisions of agreements evidencing awards; and
to make all other determinations deemed necessary or advisable for the
administration of the 1999 Omnibus Plan.
 
    The compensation committee may, in its absolute discretion, without
amendment to the 1999 Omnibus Plan, (a) accelerate the date on which any option
granted thereunder becomes exercisable, waive or amend the operation of the 1999
Omnibus Plan provisions thereunder respecting exercise after termination of
employment or otherwise adjust any of the terms of such option, (b) accelerate
the vesting or waive any condition imposed with respect to any restricted stock
and (c) otherwise adjust any of the terms applicable to any award.
 
    AWARDS UNDER THE 1999 OMNIBUS PLAN
 
    STOCK OPTIONS
 
    Unless otherwise determined by the compensation committee, options granted
pursuant to the 1999 Omnibus Plan become exercisable ratably over three years
commencing on the first anniversary of the date of grant. The "option exercise
price," which is the purchase price per share payable upon the exercise of an
option, will be established by the compensation committee; PROVIDED, HOWEVER,
that the option exercise price may be no less than the fair market value of a
share of common stock on the date of grant. The option exercise price is payable
by any one of the following methods or a combination thereof: (1) in cash or by
personal check, certified check, bank cashier's check or wire transfer; (2)
subject to the approval of the compensation committee, in stock owned by the
participant for at least six months prior to the date of
 
                                       69
 
exercise and valued at their fair market value on the effective date of such
exercise; or (3) in such other manner as the compensation committee may from
time to time authorize.
 
    RESTRICTED STOCK
 
    The compensation committee may grant restricted shares of common stock to
such persons, in such amounts, and subject to such terms and conditions,
including the attainment of performance goals, which performance goals may be
based upon one or more of the following criteria: pre-tax or after-tax income;
operating profit; return on equity, assets, capital or investment; earnings or
book value per share; sales or revenues; operating expenses; stock price
appreciation; and the implementation or completion of critical projects or
processes, as the compensation committee may determine in its discretion. Unless
the compensation committee determines otherwise, termination of employment
during the restricted period will result in the forfeiture by the participant of
all shares still subject to restrictions.
 
    OTHER AWARDS
 
    Other awards valued in whole or in part by reference to, or otherwise based
on, common stock may be granted either alone or in addition to other awards
under the 1999 Omnibus Plan. Subject to the provisions of the 1999 Omnibus Plan,
the compensation committee has the sole and complete authority to determine the
persons to whom and the time or times at which such other awards will be
granted, the number of shares of common stock to be granted pursuant to such
other awards and all other conditions of such other awards, including the
attainment of performance goals.
 
    OTHER FEATURES OF THE 1999 OMNIBUS PLAN
 
    In the event of a Change in Control, as defined in the 1999 Omnibus Plan, of
priceline.com, all outstanding awards will become fully vested and/or
immediately exercisable and any restrictions thereon will lapse.
 
    The board or the compensation committee may suspend, revise, terminate or
amend the 1999 Omnibus Plan at any time; PROVIDED, HOWEVER, that no such action
may, without the consent of a participant, reduce the participant's rights under
any outstanding award.
 
    NEW PLAN BENEFITS
 
    Inasmuch as awards under the 1999 Omnibus Plan will be granted at the sole
discretion of the compensation committee, it is not possible to determine the
awards that will be granted at the time of the offering or during 1999. See
"Option Grants in Last Fiscal Year."
 
    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion is a brief summary of the principal United States
Federal income tax consequences under current Federal income tax laws relating
to awards under the 1999 Omnibus Plan. This summary is not intended to be
exhaustive and, among other things, does not describe state, local or foreign
income and other tax consequences.
 
    NON-QUALIFIED STOCK OPTIONS
 
    An optionee will not recognize any taxable income upon the grant of a
non-qualified stock option. Priceline.com will not be entitled to a tax
deduction with respect to the grant of a non-qualified stock option. Upon
exercise of a non-qualified stock option, the excess of the fair market value of
the common stock on the exercise date over the option exercise price will be
taxable as compensation income to the optionee and will be subject to applicable
withholding taxes. Priceline.com will generally be entitled to a tax deduction
at such time in the amount of such compensation income. The optionee's tax basis
for the common stock received pursuant to the exercise of a non-qualified stock
option will equal the sum of the compensation income recognized and the exercise
price.
 
                                       70
 
    In the event of a sale of common stock received upon the exercise of a
non-qualified stock option, any appreciation or depreciation after the exercise
date generally will be taxed as capital gain or loss.
 
    INCENTIVE STOCK OPTIONS
 
    An optionee will not recognize any taxable income at the time of grant or
timely exercise of an incentive stock option and priceline.com will not be
entitled to a tax deduction with respect to such grant or exercise. Exercise of
an incentive stock option may, however, give rise to taxable compensation income
subject to applicable withholding taxes, and a tax deduction to priceline.com,
if the incentive stock option is not exercised on a timely basis (generally,
while the optionee is employed by priceline.com or within 90 days after
termination of employment) or if the optionee subsequently engages in a
"disqualifying disposition," as described below.
 
    A sale or exchange by an optionee of shares acquired upon the exercise of an
incentive stock option more than one year after the transfer of the shares to
such optionee and more than two years after the date of grant of the incentive
stock option will result in any difference between the net sale proceeds and the
exercise price being treated as long-term capital gain or loss to the optionee.
If such sale or exchange takes place within two years after the date of grant of
the incentive stock option or within one year from the date of transfer of the
incentive stock option shares to the optionee, such sale or exchange will
generally constitute a "disqualifying disposition" of such shares that will have
the following results: any excess of (a) the lesser of (i) the fair market value
of the shares at the time of exercise of the Incentive Stock Option and (ii) the
amount realized on such disqualifying disposition of the shares over (b) the
option exercise price of such shares, will be ordinary income to the optionee,
subject to applicable withholding taxes, and priceline.com will be entitled to a
tax deduction in the amount of such income. Any further gain or loss after the
date of exercise generally will qualify as capital gain or loss and will not
result in any deduction by priceline.com.
 
    RESTRICTED STOCK
 
    A grantee will not recognize any income upon the receipt of restricted stock
unless the holder elects under Section 83(b) of the Code, within thirty days of
such receipt, to recognize ordinary income in an amount equal to the fair market
value of the restricted stock at the time of receipt, less any amount paid for
the shares. If the election is made, the holder will not be allowed a deduction
for amounts subsequently required to be returned to priceline.com. If the
election is not made, the holder will generally recognize ordinary income, on
the date that the restrictions to which the restricted stock are subject are
removed, in an amount equal to the fair market value of such shares on such
date, less any amount paid for the shares. At the time the holder recognizes
ordinary income, priceline.com generally will be entitled to a deduction in the
same amount.
 
    Generally, upon a sale or other disposition of restricted stock with respect
to which the holder has recognized ordinary income, for example, if a Section
83(b) election was previously made or the restrictions were previously removed,
the holder will recognize capital gain or loss in an amount equal to the
difference between the amount realized on such sale or other disposition and the
holder's basis in such shares.
 
    OTHER TYPES OF AWARDS
 
    The grant of any other stock-based award generally will not result in income
for the grantee or in a tax deduction for priceline.com. Upon the settlement of
such an award, the grantee will recognize ordinary income equal to the aggregate
value of the payment received, and priceline.com generally will be entitled to a
tax deduction in the same amount.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY
 
    Section 145 of the Delaware General Corporation Law authorizes a
corporation's board of directors to grant indemnity to directors and officers in

circumstances for liabilities, including reimbursement for expenses incurred,
arising under the Securities Act of 1933, as amended, which is commonly referred
to as the "Securities Act."
 
    As permitted by Delaware law, priceline.com's certificate of incorporation
includes a provision that eliminates the personal liability of its directors for
monetary damages for breach of fiduciary duty as a director, except for
liability (1) for any breach of the director's duty of loyalty to priceline.com
or its stockholders; (2) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (3) under Section 174 of

purchases; or (4) for any transaction from which the director derived an
improper personal benefit.

provides that (1) priceline.com is required to indemnify its directors and
officers to the fullest extent permitted by Delaware law, subject to certain
very limited exceptions; (2) priceline.com is permitted to indemnify its other
employees to the extent that it indemnifies its officers and directors, unless
otherwise required by law, its certificate of incorporation, its by-laws or
agreements; (3) priceline.com is required to advance expenses, as incurred, to
its directors and officers in connection with a legal proceeding to the fullest
extent permitted by Delaware law, subject to certain very limited exceptions;

RELATIONSHIP WITH WALKER DIGITAL
 
   
    The priceline.com core buyer driven commerce business model and related

Priceline.com also granted Walker Digital a perpetual, non-exclusive,
royalty-free right and license to use the intellectual property related to the
priceline.com service for non-commercial internal research and development
purposes. Priceline.com also has the right to purchase at fair market value any
intellectual property that is owned and subsequently acquired, developed or
discovered by Walker Digital that will provide significant value in the use or
commercial exploitation of the priceline.com system.
    
 
   
    Walker Digital and priceline.com provide each other with a variety of
services. The services provided by priceline.com include management and
administrative services. The services provided by Walker Digital include (1)
research and development assistance; (2) patent and intellectual property
services; and (3) technical support. Walker Digital also subleases a portion of
its Stamford, Connecticut facilities to priceline.com on a month-to-month basis.
Additionally, priceline.com has guaranteed Walker Digital's obligations under a
lease of 2,500 square feet for office space in a building in New York City that
is used by both companies. The lease provides for annual rental payments of
approximately $170,000 plus expenses for a term of five years.
    
 
   
    Pursuant to the terms of the indemnification obligations contained in the
Purchaser and Intercompany Agreement, Walker Digital has agreed to indemnify
priceline.com for damages, liability and legal expenses incurred in connection
with the Marketel litigation.

    Priceline.com issued a promissory note to Walker Digital for $1,000,000 in
June 1998. The promissory note bore interest at a rate of 6% per annum and was
due June 30, 1999. The Note has been repaid.

thereof, including dividend rights, conversion rights, voting rights, terms of
redemption, liquidation preferences and the number of shares constituting any
series or the designation of such series. The issuance of preferred stock could

    The underwriters are offering the shares of common stock subject to their
acceptance of the shares from priceline.com and subject to prior sale. The
underwriting agreement provides that the obligations of the several underwriters
to pay for and accept delivery of the shares of common stock offered hereby are
subject to the approval of certain legal matters by their counsel and to certain
other conditions. The underwriters are obligated to take and pay for all of the
shares of common stock offered hereby, other than those covered by the
over-allotment option described below, if any are taken.
 
    The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price set forth on the cover
page hereof and part to certain dealers at a price that represents a concession
not in excess of $   per share under the public offering price. Any underwriter
may allow, and such dealers may reallow, a concession not in excess of $   per
share to other underwriters or to certain other dealers. After the initial
offering of the shares of common stock, the offering price and other selling
terms may from time to time be varied by the representatives.
 
    Pursuant to the underwriting agreement, priceline.com has granted to the
underwriters an option, exercisable for 30 days from the date of this
prospectus, to purchase up to an aggregate of 1,500,000 additional shares of
common stock at the public offering price set forth on the cover page hereof,
less underwriting discounts and commissions. The underwriters may exercise such
option solely for the purpose of covering over-allotments, if any, made in
connection with the offering of the shares of common stock offered hereby. To
the extent such option is exercised, each underwriter will become obligated,
subject to certain conditions, to purchase approximately the same percentage of
such additional shares of common stock as the number set forth next to such
underwriter's name in the preceding table bears to the total number of shares of
common stock set forth next to the names of all underwriters in the preceding
table. If the underwriters exercise the over-allotment option in full, the total
public offering price will be $         , the total underwriting discounts and
commissions will be $         and the total proceeds to priceline.com will be
$         .
 
    The underwriters have informed priceline.com that they do not intend sales
to discretionary accounts to exceed five percent of the total number of shares
of common stock offered by them.
 
    At the request of priceline.com, the underwriters have reserved up to
850,000 shares of common stock offered hereby for sale at the initial public
offering price to certain employees of priceline.com and to certain other
persons. The number of shares available for sale to the general public will be
reduced to the extent that such persons purchase such reserved shares. Any
reserved shares not so purchased will be
 
                                       83
 
offered by the underwriters to the general public on the same basis as the other
shares of common stock offered hereby.
 
   
    The common stock has been approved for quotation on the Nasdaq National
Market under the symbol "PCLN."
    
 
    Each of priceline.com and the directors, executive officers and certain
other securityholders of priceline.com has agreed that, without the prior
written consent of Morgan Stanley & Co. Incorporated on behalf of the
underwriters, it will not, during the period ending 180 days after the date of
this prospectus:
 
    - offer, pledge, sell, contract to sell, sell any option or contract to
      purchase, purchase any option or contract to sell, grant any option, right
      or warrant to purchase, lend, or otherwise transfer or dispose of,
      directly or indirectly, any shares of common stock or any securities
      convertible into or exercisable or exchangeable for common stock;
 
    - enter into any swap or other arrangement that transfers to another, in
      whole or in part, any of the economic consequences of ownership of the
      common stock, whether any such transaction described above is to be
      settled by delivery of common stock or such other securities, in cash or
      otherwise; or
 
    - file a registration statement (in the case of priceline.com) other than a
      registration statement on Form S-8 covering shares of common stock subject
      to outstanding options under the 1997 Omnibus Plan or shares of common
      stock subject to options to be issued under the 1999 Omnibus Plan.
 
    The restrictions described in the previous paragraph do not apply to certain
circumstances, including:
 
    - the sale of the shares to the underwriters;
 
    - the issuance by priceline.com of restricted stock awards under
      priceline.com's existing employee benefit plans or of shares of common
      stock upon the exercise of an option or a warrant or the conversion of a
      security outstanding on the date of this prospectus;
 
    - the grant of options to certain officers, directors, employees or
      consultants provided such options are not exercisable prior to the end of
      the lock-up period;
 
    - the issuance of warrants (or shares of capital stock upon the exercise of
      such warrants) to suppliers or other entities providing products or
      services to priceline.com in connection with entering into certain supply,
      adaptive marketing or other similar arrangements, provided that the
      recipient of such warrants or shares agrees to be bound by the foregoing
      provisions; or
 
   
    - the sale or other transfer of any shares of common stock by certain of the
      foregoing persons to any associate (as such term is defined in Rule 12b-2
      under the Exchange Act) if such person agrees to be bound by the foregoing
      provisions.
    
 
In addition, the stockholders of priceline.com have agreed that, without the
prior written consent of Morgan Stanley & Co. Incorporated on behalf of the
underwriters, neither it nor any of its affiliates will, during the period
ending 180 days after the date of the prospectus, make any demand for, or
exercise any right with respect to, the registration of any shares of common
stock or any security convertible into or exercisable or exchangeable for common
stock.
 
    In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of the common stock, the underwriters may bid for, and purchase, shares of
common stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
common stock in the offering, if the syndicate repurchases previously
distributed common stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these
 
                                       84
 
activities may stabilize or maintain the market price of the common stock above
independent market levels. The underwriters are not required to engage in these
activities, and may end any of these activities at any time.
 
    Priceline.com and the underwriters have agreed to indemnify each other
against certain liabilities, including liabilities under the Securities Act.
 
    E*TRADE has entered into a co-marketing agreement with priceline.com to
establish an adaptive marketing program under which E*TRADE will compensate
priceline.com for offering priceline.com customers the opportunity to open an
account with E*TRADE while visiting or making an offer on the priceline.com Web
site. See "Business--Strategic Alliances--Adaptive Marketing Alliances." As the
first phase of this program, priceline.com and E*TRADE have established the
Customer Affinity Share Purchase Program under which customers of priceline.com
who are also account holders at E*TRADE will receive priority in the allocation
by E*TRADE of priceline.com shares in this offering, subject to a maximum
allocation of 100 shares per customer account and limited by the total number of
shares made available to E*TRADE. In order to be eligible to receive priority
allocation of priceline.com shares, priceline.com customers who are not already
E*TRADE customers must open an account with E*TRADE, subject to normal
eligibility criteria and must submit timely indications of interest in
accordance with E*TRADE's normal procedures.
 
PRICING OF THE OFFERING
 
    Prior to this offering, there has been no public market for the common
stock. The initial public offering price will be determined by negotiations
between priceline.com and the representatives. Among the factors to be
considered in determining the initial public offering price will be the future
prospects of priceline.com and its industry in general, sales, earnings and
certain other financial and operating information of priceline.com in recent
periods, and the price-earnings ratios, price-sales ratios, market prices of
securities and certain financial and operating information of companies engaged
in activities similar to those of priceline.com. The estimated initial public
offering price range set forth on the cover page of this prospectus is subject
to change as a result of market conditions and other factors.

INDEPENDENT AUDITORS' REPORT
    
 
The Board of Directors and Stockholders of
priceline.com Incorporated and Priceline Travel, Inc.
 
    We have audited the accompanying combined balance sheets of priceline.com
Incorporated and Priceline Travel, Inc. (collectively the "Company") as of
December 31, 1997 and 1998 and the related combined statements of operations,
changes in stockholders' equity and cash flows for the period July 18, 1997
(Inception) to December 31, 1997 and the year ended December 31, 1998. These
combined financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these combined
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the combined financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
    In our opinion, such combined financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 1997
and 1998 and the results of their operations and their cash flows for the period
July 18, 1997 to December 31, 1997 and the year ended December 31, 1998 in
conformity with generally accepted accounting principles.
 
    As discussed in Note 13, the accompanying 1998 financial statements have
been restated.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. BUSINESS DESCRIPTION
 
    Priceline.com ("priceline.com") has pioneered a unique new type of
e-commerce known as a "demand collection system" that enables consumers to use
the Internet to save money on a wide range of products and services while
enabling sellers to generate incremental revenue. Using a simple and compelling
consumer proposition--"name your price," priceline.com collects consumer demand,
in the form of individual customer offers guaranteed by a credit card, for a
particular product or service at a price set by the customer. Priceline.com then
either communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether the customer's
offer can be fulfilled on the basis of the pricing information and rules
established by the sellers. Consumers agree to hold their offers open for a
specified period of time and once fulfilled, offers cannot be canceled. By
requiring consumers to be flexible with respect to brands, sellers and/or
product features, priceline.com enables sellers to generate incremental revenue
without disrupting their existing distribution channels or retail pricing
structures. Priceline.com commenced its service on April 6, 1998 with the sale
of leisure airline tickets. During 1997, the Company had been in the development
stage. Priceline.com's services were expanded to include the sale of new
automobiles, on a test basis, in July 1998, hotel room reservations in October
1998, and home mortgages in January 1999.
 
   
    Priceline.com was founded as a limited liability company ("LLC") in July
1997 and converted to a corporation in July 1998. All LLC units and options and
warrants to purchase units, were converted in July 1998 to common stock of
priceline.com ("Common Stock") and options and warrants to purchase Common
Stock. For presentation purposes all such LLC units, and options and warrants to
purchase units are presented as Common Stock or options and warrants to purchase
Common Stock. Priceline Travel, Inc. ("Priceline Travel") holds the travel
agency license used to effect airline ticket sales. Priceline Travel is wholly
owned by the founding stockholder and Vice-Chairman of priceline.com.
Priceline.com has a call option to purchase Priceline Travel for nominal
consideration. Priceline.com and Priceline Travel are entities under common
control, accordingly, the financial statements of the two companies are
presented on a combined basis. Priceline Travel will merge into priceline.com
during the first quarter of 1999. Priceline.com and Priceline Travel are
referred to, collectively, as the Company.
    
 
    Walker Digital Corporation ("Walker Digital"), a research and development
company, developed the priceline.com service and the business model and related
intellectual property rights underlying the priceline.com service, the rights
for which were transferred to the Company on July 18, 1997. Walker Digital had
no operations and no revenues related to the assets transferred to
priceline.com. Walker Digital was founded and is controlled by the founding
stockholder and Vice Chairman of priceline.com. Walker Digital has also been
providing the Company with a variety of services including subleasing office
facilities to the Company on a month to month basis. Charges to the Company for
such services aggregated $19,813 and $706,160 during the period July 18, 1997 to
December 31, 1997 and the year ended December 31, 1998, respectively. Such
amounts are included in general and administrative expense. In addition, the
Company charged Walker Digital $95,874 and $384,831 for the period July 18, 1997
to December 31, 1997 and the year ended December 31, 1998, respectively, for
shared expenses. Such reimbursement has been offset against general and
administrative expenses in the accompanying combined statements of operations.
Several of the Company's executive offers and other key employees are also
officers, employees and/or stockholders of Walker Digital.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF COMBINATION AND BASIS OF PRESENTATION--The combined financial
statements for all periods presented include the financial statements of
priceline.com and Priceline Travel. The combined financial
 
                                      F-7
 
             PRICELINE.COM INCORPORATED AND PRICELINE TRAVEL, INC.
 
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
statements have been prepared in accordance with generally accepted accounting
principles. All significant intercompany transactions have been eliminated.
 
    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS--The Company's financial instruments,
including cash and cash equivalents, restricted bank deposits, accounts
receivable-net and accounts payable, are carried at cost which approximates
their fair value because of the short-term maturity of these financial
instruments. The carrying value of the capital lease obligations and long-term
debt approximates fair value because the interest rates on these obligations are
comparable to the interest rates that could have been obtained at the date of
the balance sheet.
 
    CASH AND CASH EQUIVALENTS, RESTRICTED BANK DEPOSITS--The Company invests
excess cash primarily in money market accounts, certificates of deposits, and
short-term commercial paper. All highly liquid instruments with an original
maturity of three months or less are considered cash equivalents. Restricted
bank deposits collateralize letters of credit issued in favor of certain
airlines.
 
    NOTE RECEIVABLE FROM STOCKHOLDER--Represents a note receivable related to
the sale of common stock that was subsequently paid on January 9, 1998.
 
    PROPERTY AND EQUIPMENT--Property and equipment are stated at historical
cost. Depreciation and amortization of property and equipment is computed on a
straight-line basis, generally over the estimated useful lives of the assets or,
when applicable, the life of the lease, whichever is shorter. Capitalized
software costs represent costs paid to third parties and are amortized on a
straight-line basis over their estimated useful lives. Maintenance and repairs
are charged directly to expense as incurred.
 
   
    INTANGIBLE ASSETS--The Company acquired certain patent rights covering the
core buyer-driven commerce system and the method and system for pricing and
selling airline ticket options from a Walker Digital affiliate on July 18, 1997
in exchange for 6,895,833 shares of common stock. Since the transfer was between
entities under common control, it was recorded at the historical cost of the
asset transferred, which was zero.
    
 
    IMPAIRMENT OF LONG-LIVED ASSETS--The Company evaluates the recoverability of
its long-lived assets in accordance with Statement of Financial Accounting
Standards ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of." SFAS No. 121 requires recognition
of impairment of long-lived assets in the event the net book value of such
assets exceeds the future undiscounted cash flows attributable to such assets.
 
    REVENUES AND COST OF REVENUES--The manner in which revenues are recognized
differs depending on the product or service sold through the priceline.com
service. With respect to airline ticket or hotel reservation services, revenues
are generated by transactions with customers who make offers to purchase airline
tickets and hotel rooms supplied by participating sellers. All offers are
guaranteed by a customer credit card. Credit cards are the only form of payment
accepted by priceline.com. Revenues and related costs are recognized if, and
when, the Company accepts the customer's offer and charges the customer's credit
card. Because priceline.com is the merchant of record in these transactions,
revenue for these services includes

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
the amount billed to the customer, net of certain transportation taxes and fees.
Airline and hotel revenues may be supplemented by fees that are paid to the
Company by third parties in connection with adaptive marketing programs. With
respect to automobile and mortgage services, fees or other payments payable by
the seller and/or the customer are recognized as revenue. Because priceline.com
acts as an intermediary between the customer and the seller in these
transactions, revenue for these products and services is recorded at the amount
of the fee received in connection with the transaction, and not on the value of
the underlying transaction, when the transaction is completed. Automobile and
mortgage services revenues may also include fees from third parties for adaptive
marketing programs.
 
    Revenues from adaptive marketing programs are earned when customers elect to
increase their offering price, and thus the likelihood of a successful
transaction, at no additional costs, by participating in a sponsor promotion.
Priceline.com earns fee income from the corporate sponsor of each adaptive
marketing program based primarily upon customer participation levels. During
1998, the Company generated approximately $4,037,000 of revenues from adaptive
marketing programs. All of these adaptive marketing revenues resulted from fees
paid to the Company by Capital One Bank in connection with a credit card
promotion--see Note 12.
 
    Priceline.com expressly permits only credit cards as an acceptable form of
payment from its consumers. Consequently, the Company believes that it does not
have a significant risk of loss with respect to customer transactions. On rare
occasions, the Company provides credit card refunds to individual customers to
satisfy disputes and complaints. The Company accrues for expected credit card
charge-backs and classifies the resulting expense as an addition to the
allowance for doubtful accounts. The Company extends customary payment terms to
corporate customers such as automobile dealers and adaptive marketing sponsors.
The Company did not experience any uncollectible corporate accounts receivable
in 1998.
 
    Cost of revenues includes product costs and the pro rata amount of the Delta
Warrant earned prior to the December 31, 1998 measurement date based on their
performance through that date--see Note 6.
 
    SUPPLIER START-UP WARRANT COSTS--Supplier start-up warrant costs includes
the value of warrants issued to secure certain airline alliances and
relationships including the value of the Delta Warrant net of the amount
included in cost of revenues--see Note 6.
 
    SALES AND MARKETING--Sales and marketing expenses are comprised primarily of
costs of radio and newspaper advertising, costs of the third-party offer-taking
call center, credit card processing fees, provisions for customer credit card
charge-backs and compensation for the Company's sales and marketing personnel.
All sales and marketing costs are expensed as incurred.
 
    SYSTEMS AND BUSINESS DEVELOPMENT--Systems and business development expenses
are comprised primarily of compensation to the Company's information systems and
product development staff and payments to outside contractors, data
communications and other expenses associated with operating the Company's Web
site, depreciation on computer hardware and licensing fees for computer
software. Such costs are expensed as incurred.
 
    INTEREST INCOME (EXPENSE), NET--Interest income (expense), net includes
interest income of $523 and $633,294 and interest expense of $835 and $84,920
for the period July 18, 1997 to December 31, 1997 and the year ended December
31, 1998, respectively.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    EQUITY-BASED COMPENSATION--The Company accounts for stock- based employee
compensation arrangements in accordance with provisions of Accounting Principles
Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and
complies with the disclosure provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation." Under APB Opinion No. 25, compensation expense is
based on the difference, if any, on the date of grant, between the fair value of
priceline.com's stock and the exercise price.
 
    The Company accounts for equity instruments issued to non-employees in
accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force
("EITF") Issue No. 96-18, "Accounting for Equity Instruments That Are Issued to
Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or
Services." All transactions in which goods or services are the consideration
received for the issuance of equity instruments are accounted for based on the
fair value of the consideration received or the fair value of the equity
instrument issued, whichever is more reliably measurable. The measurement date
of the fair value of the equity instrument issued is the earlier of the date on
which the counterparty's performance is complete or the date on which it is
probable that performance will occur.
 
    INCOME TAXES--The Company accounts for income taxes in accordance with SFAS
No. 109, "Accounting for Income Taxes," which requires recognition of deferred
tax liabilities and assets for the expected future tax consequences of events
that have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
temporary difference between the financial statement and tax basis of assets and
liabilities using presently enacted tax rates in effect. Valuation allowances
are established when necessary to reduce deferred tax assets to the amounts
expected to be realized.
 
    During the period that priceline.com operated as an LLC, it was treated
substantially as a partnership for tax purposes and, accordingly, the tax effect
of its activities accrued to its members through July 1998.
 
    NET LOSS PER SHARE--The Company computes net loss per share in accordance
with SFAS No. 128, "Earnings Per Share" which requires dual presentation of
basic earnings per share ("EPS") and diluted EPS.
 
   
    Basic earnings per share is computed using the weighted average number of
common shares outstanding during the period. Diluted earnings per share is
computed using the weighted average number of common shares and potentially
dilutive shares outstanding during the period. Potential common shares consist
of the incremental common shares issuable upon conversion of the Series A and
Series B Convertible Preferred Stock (using the if-converted method) and shares
issuable upon the exercise of stock options and warrants (using the treasury
stock method). At December 31, 1998, Series A and Series B Convertible Preferred
Stock were convertible into 21,610,854 shares and 17,296,874 shares,
respectively, and options and warrants to purchase 42,181,997 shares of Common
Stock were outstanding. Outstanding convertible preferred stock, warrants and
options could potentially dilute basic earnings per share in the future but have
not been included in the computation of diluted net loss per share as the impact
would have been antidilutive for the periods presented.
    
 
    BUSINESS RISK--Business risks include the following:
 
    Competition--The markets for the products and services offered on the
priceline.com service are intensely competitive. The Company competes with both
traditional distribution channels and online services. The Company currently or
potentially competes with a variety of companies with respect to each product or
services offered. The Company potentially faces competition from a number of
large online

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
services that have expertise in developing online commerce and in facilitating
Internet traffic. Many competitors have significant competitive advantages. For
example, airlines, hotels and other suppliers also sell their products and
services directly to consumers and have established Web sites. Internet
directories, search engines and large traditional retailers have significantly
greater operating histories, customer bases, technical expertise, brand
recognition and/or online commerce experience than the Company. In addition,
certain competitors may be able to devote significantly greater resources to
furthering their business.
 
    Dependence on Airline Industry and Certain Carriers--The Company's near
term, and possibly long term, prospects are significantly dependent upon the
sale of leisure airline tickets. Sales of leisure airline tickets and revenues
derived from related adaptive marketing programs represented essentially all of
the Company's revenues for the year ended December 31, 1998. Sales of airline
tickets from the Company's three largest airline suppliers accounted for
approximately 95% of airline ticket revenue for the year ended December 31,
1998. As a result, currently the Company is substantially dependent upon the
continued participation of these three airlines in the priceline.com service in
order to maintain and continue to grow its total airline ticket revenues.
Significantly reducing the Company's dependence on the airlines is likely to
take a long time and there can be no guarantee that the Company will succeed in
reducing that dependence.
 
    Risks Associated with Brand Development--The Company intends to continue to
pursue an aggressive brand-enhancement strategy, which will include mass market
and multimedia advertising, promotional programs and public relations
activities. To increase awareness of the priceline.com brand and expand it to a
wide range of products and services, the Company will need to continue to spend
significant amounts on advertising and promotions. These expenditures may not
result in a sufficient increase in revenues to cover such advertising and
promotions expenses.
 
    CONCENTRATION OF CREDIT RISK--Financial instruments which potentially
subject the Company to concentrations of credit risk are principally bank
deposits and accounts receivable. Cash and cash equivalents and restricted bank
deposits are deposited with high credit quality financial institutions. Accounts
receivable typically represent credit card purchases and are derived from the
revenues earned from customers in the U.S. and are denominated in U.S. dollars.
Accounts receivable balances are typically settled through customer credit cards
and, as a result, the majority of accounts receivable are collected upon
processing of credit card transactions. The Company maintains an allowance for
uncollectible accounts based upon the expected collectibility of accounts
receivable. During the year ended December 31, 1998, approximately 11% of
revenues were generated from one vendor participating in an adaptive marketing
program. As of December 31, 1998, amounts due from this vendor represented
approximately 54% of accounts receivable.
 
    COMPREHENSIVE INCOME--Effective January 1, 1998, the Company adopted SFAS
No. 130, "Reporting Comprehensive Income." Under SFAS 130 changes in net assets
of an entity resulting from transactions and other events and circumstances from
non-owner sources are reported in a financial statement for the period in which
they are recognized. Because there were no such changes, adoption of SFAS 130
did not impact the combined financial statements of the Company.
 
    SEGMENT REPORTING--Effective January 1, 1998, the Company adopted SFAS No.
131, "Disclosures About Segments of an Enterprise and Related Information." The
Company operates as a single segment and will evaluate additional segment
disclosure requirements as it expands its operations.

    RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1998, Statement of Financial Accounting Standards SFAS No 133
"Accounting for Derivative Instruments and Hedging Activities" was released. The
statement requires the recognition of all derivatives as either assets or
liabilities in the balance sheet and the measurement of those instruments at
fair value. The accounting for changes in the fair value of a derivative depends
on the planned use of the derivative and the resulting designation. The Company
is required to implement the statement in the first quarter of fiscal 2000. The
Company has not used derivative instruments and believes the impact of adoption
of this statement will not have a significant effect on the financial
statements.
 
    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, "Accounting for Costs of Computer Software
Developed or Obtained for Internal Use." This SOP is effective for fiscal years
beginning after December 15, 1998. This SOP requires capitalization of certain
costs of computer software developed or obtained for internal use.
 
3. ACCOUNTS RECEIVABLE
 
    A summary of the activity in the allowance for uncollectible accounts for
the year ended December 31, 1998 is as follows:
 

AMOUNT ---------- Provision charged to expense.......................................................................... $ 580,448 Charge offs........................................................................................... (289,625) ---------- Balance at end of period.............................................................................. $ 290,823 ---------- ----------

 

 

 
 
4. PROPERTY AND EQUIPMENT
 
    Property and equipment at December 31, 1997 and 1998 consists of the
following:
 

ESTIMATED USEFUL LIVES (YEARS) 1997 1998 ------------ ------------ ------------ Computer equipment and software......................................... 3 $ 1,144,263 $ 7,034,088 Office equipment........................................................ 3 89,846 584,034 Furniture and fixtures.................................................. 7 158,006 380,847 ------------ ------------ Total................................................................... 1,392,115 7,998,969 Less accumulated depreciation and amortization.......................... 211,996 2,072,092 ------------ ------------ Property and equipment--net............................................. $ 1,180,119 $ 5,926,877 ------------ ------------ ------------ ------------

 

 

 
 
    Depreciation and amortization expense was $211,996 and $1,860,096 for the
period July 18, 1997 to December 31, 1997 and the year ended December 31, 1998,
respectively.
 
5. LONG-TERM DEBT
 
    In April 1998, priceline.com issued a promissory note to an investor for
$1,000,000. The promissory note bears interest at a rate of 6% per annum and
matures on April 15, 2003. In connection with the

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
5. LONG-TERM DEBT (CONTINUED)
promissory note, priceline.com issued detachable warrants to purchase 62,500
common shares at $0.80 per share. The portion of the proceeds allocable to the
warrant, estimated fair value of $12,795, was accounted for as additional
paid-in capital. The fair value of the warrants was determined using an option
pricing model. The discount will be recorded as interest expense over the term
of the promissory note. At December 31, 1998, the principal balance of the
promissory note, net of unamortized discount, was $989,018.
 
6. STOCKHOLDERS' EQUITY
 
    Combined stockholders' equity at December 31, 1997 and 1998 consists of the
following:
 
   

1997 1998 ----------- -------------- Priceline.com Incorporated: Common stock, $0.008 par value--authorized 300,000,000 shares at December 31, 1997 and 1998 issued and outstanding, 51,669,719 and 93,225,199 shares at December 31, 1997 and 1998, respectively....................................................... $ 413,358 $ 745,802 Convertible Preferred Stock, $0.01 par value; authorized 150,000,000 shares: Series A--$1.16 liquidation value; issued and outstanding 17,288,684 shares....... -- 172,887 Series B--$4.00 liquidation value; issued and outstanding, 13,837,500 shares...... -- 138,375 Additional paid-in capital.......................................................... 836,642 171,151,823 Priceline Travel, Inc: Common stock, $1 par value--3,000 shares authorized, issued and outstanding......... 3,000 3,000 Additional paid-in capital.......................................................... 3,363 3,363 Accumulated deficit.................................................................

(1,257,119) 55,275,845 ----------- --------------

 

 

 
    
 
    On July 18, 1997, priceline.com issued 42,990,211 shares of Common Stock for
the initial contributed services of the founders. No compensation expense was
recognized for the contributed services as priceline.com was in the earliest
phases of development. Such services included conceiving the priceline.com
business model, developing business strategies and operating plans, initiating
contact with airline suppliers and raising capital. There were no employment
agreements related to the services initially contributed and/or the shares
issued in respect of such shares.
 
   
    Also, on July 18, 1997, priceline.com issued 6,895,833 shares of Common
Stock to Walker Digital in exchange for the transfer by Walker Digital to
priceline.com all of the rights, title, and interest in certain patents and
patent applications relating to buyer driven commerce.
    
 
    In July 1998, priceline.com also issued 8,125,000 shares of Common Stock, to
the Chairman and Chief Executive Officer which resulted in the recognition of a
one time charge of $6,500,000 with respect to these shares. The shares were
issued as compensation for agreeing to accept the position.
 
    In July 1998, pursuant to an agreement between priceline.com and two
partnerships affiliated with General Atlantic Partners, LP (collectively "GAP"),
priceline.com sold to GAP a total of 17,288,684 shares

of Series A Convertible Preferred Stock, par value $0.01 per share (the "Series
A Preferred Stock") for $20,000,000.
 
    In December 1998, priceline.com raised net proceeds of approximately
$54,414,550 by completing a private placement of an aggregate of 13,837,500
shares of its Series B Convertible Preferred Stock (the "Series B Preferred
Stock") with several investors, including GAP and Vulcan Ventures Incorporated.
Fees of $850,000 have been paid to a company, in which a director of
priceline.com is a director and stockholder, in connection with this
transaction.
 
    Shares of the Series A and Series B Preferred Stock are automatically
convertible, subject to antidilution adjustment, into an equal number of shares
of Common Stock upon an initial public offering of the Company. The holders of
the Series A and Series B Preferred Stock vote together as a single class with
the holders of Common Stock. If the Company has not consummated an initial
public offering by December 1999, the conversion price of Series B Preferred
Stock will be adjusted to $1.97 per share. Since the Series B Preferred Stock
contained this beneficial conversion feature at the date of issue, the Company
allocated a portion of the proceeds equal to the value of the feature,
$34,650,000, to additional paid-in capital. This amount will be amortized over
one year. Amortization will cease if an initial public offering is completed
within one year and the Series B Preferred Stock convert at $3.20 per share. The
shares of the Series A and Series B Preferred Stock rank senior to the Common
Stock with respect to liquidation and equal to the Common Stock with respect to
dividends.
 
    In April 1998, priceline.com issued warrants to purchase 125,000 shares of
Common Stock, at a zero exercise price, to a non-employee in exchange for
services rendered to the Company. The estimated fair value of the warrants at
the date of grant of $100,000 was based on the value of the equivalent shares as
of the grant date, that is 125,000 shares at $0.80 per share, and has been
reflected as sales and marketing expense and additional paid-in-capital.
 
    In April 1998, priceline.com issued warrants to purchase 62,500 shares of
Common Stock at an exercise price of $0.80 per share in conjunction with a
promissory note (see Note 5--Long-Term Debt).
 
   
    In August 1998, priceline.com entered into a warrant agreement with Delta
Air Lines ("Delta") to purchase up to 18,892,603 shares of Common Stock at an
exercise price of approximately $0.93 per share ("Delta Warrant") for agreeing
to participate in the priceline.com service. Vesting was contingent upon
achievement of certain predetermined performance thresholds. However, there was
no penalty for failure to provide ticket inventory to satisfy these performance
thresholds. Accordingly, no expense was recorded when the warrant was issued. On
December 31, 1998, the Company amended its agreement with Delta to eliminate the
vesting contingencies and fix the number of shares subject to the warrant at
18,619,402. The warrants were immediately vested on the date of grant, in that
they are not subject to any forfeiture for any reason. The amended Delta Warrant
will become exercisable at the earlier of seven years or over three years upon
the achievement of certain performance thresholds. The agreement does not
require Delta to make any performance commitments, is non-exclusive and allows
Delta to participate in other programs similar to the priceline.com service.
Accordingly, the Company recognized approximately $58.7 million of expense based
upon the fair value of the warrant on December 31, 1998, of which $3 million is
included in cost of revenues-supplier warrant costs and $55.7 million is
included in expenses-supplier start-up warrant costs in the accompanying
statement of operations.
    
 
    On December 31, 1998, priceline.com issued warrants to purchase 937,500
shares of Common Stock at an exercise price of $3.20 per share to three airlines
in recognition of their being among the original

participants in the priceline.com service. Because there are no requirements as
to the nature or length of that participation and the warrants are not subject
to forfeiture for any reason, the Company recognized approximately $2.3 million
of expense based upon the fair value of the warrants at December 31, 1998, which
is included in expenses-supplier start-up warrant costs in the accompanying
statement of operations.
 
    On January 29, 1999, priceline.com issued warrants to an airline to purchase
1,250,000 shares of Common Stock at an exercise price of $6.40 per share. The
warrants become exercisable as follows, 50% on January 29, 2000 and 50% on
January 29, 2001. The agreement requires the airline to make available to
priceline.com airline ticket inventory on certain specified terms and conditions
for two years. If the airline does not provide the specified airline ticket
inventory, the unexercised warrants are returnable and in addition, there is a
penalty of $1.0 million in the first year and $0.5 million in the second year.
The fair value of the warrant of $3.1 million at the grant date was capitalized
and will be amortized over the two year period during which services will be
provided to the Company.
 
    The fair value of the airline warrants was based on a third party valuation
using an option pricing model and the following assumptions:
 

OTHER DELTA AIRLINE WARRANTS WARRANTS ----------- ------------- Stock Price........................................................................ $3.20 $3.20 Exercise Price..................................................................... $0.93 $3.20-$6.40 Term............................................................................... 7 years 3-4 years Volatility......................................................................... 132% 132% Risk Free Rate..................................................................... 4.6% 4.6%

 

 

 
 
    As of December 31, 1998, no warrants had been exercised.
 
7. STOCK OPTION PLAN
 
    Priceline.com has adopted the 1997 Omnibus Plan (the "Plan"), which provides
for grants of options as incentives and rewards to encourage employees,
officers, consultants and directors in the long term success of the Company. The
Plan provides for grants of options to purchase up to 23,875,000 shares at a
purchase price equal to the fair market value on the date of grant. Generally,
the options vest over three years from the date of grant. In accounting for the
Plan, the Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options. When the exercise price of employee
stock options issued under the plan equaled the fair value of the underlying
stock on the date of grant, no compensation expense was recorded. Compensation
expense was recognized for the fair value of the options granted to
non-employees and to the extent fair value of the underlying stock exceeded the
exercise price of employee stock options. Compensation expense, included in
general and administrative, recognized during the year ended December 31, 1998

7. STOCK OPTION PLAN (CONTINUED)
    The following summarizes the transactions pursuant to the Plan:
 

WEIGHTED RANGE AVERAGE OF SHARES OPTION PRICE SHARE ------------ ------------- ------------ Granted during 1998..................................................... 23,449,219 $ 0.93 $ 0.80-3.20 Forfeited............................................................... (189,374) 0.80 0.80 Cancelled............................................................... (815,625) 0.80 0.80 ------------ Balance at December 31, 1998............................................ 22,444,220 0.94 ------------ ------------ Exercisable at December 31, 1998........................................ None ------------ ------------ Available for grant at December 31, 1998................................ 1,430,780 ------------ ------------

 

 

 
 
    Had compensation costs been determined based upon the fair value at grant
date, the Company's pro forma net loss and pro forma net loss per share for the
year ended December 31, 1998 would have been reported as follows:
 

REPORTED PRO FORMA -------------- -------------- Net loss......................................................................... $ 112,242,499 $ 114,613,228 Net loss applicable to common shareholders....................................... 114,425,923 116,796,653 Basic and diluted loss per common share.......................................... 1.41 1.44

 

 

 
 
    The fair value of each option grant was determined on the date of grant
using the minimum value method. The weighted average fair value of options
granted during 1998 was estimated to be approximately $0.15 on the dates of
grant using the minimum value method and the following assumptions: volatility
of 0%, risk free interest rate of 6.00% and an expected life of 3 years,
respectively. The Plan also provides for the grant of tandem stock appreciation
rights, stand-alone stock appreciation rights, phantom stock and other forms of
equity based incentive awards which do not reduce the number of shares with
respect to which incentive awards may be granted. No such awards were made as of
December 31, 1998.
 
    In February 1999, priceline.com established the 1999 Omnibus Plan (the "1999
Plan"), which provides for grants of options as incentives and rewards to
encourage employees, officers, consultants and directors in the long term
success of the Company. The Plan provides for grants of options to purchase up
to 9,375,000 shares at a purchase price equal to the fair market value on the
date of grant. Generally, the options vest over three years from the date of
grant. The Plan also provides for the grant of tandem stock appreciation rights,
stand-alone stock appreciation rights, phantom stock and other forms of equity
based incentive awards which do not reduce the number of shares with respect to
which incentive awards may be granted.
 
8. TAXES
 
    INCOME TAXES--Through July 31, 1998, priceline.com operated as a limited
liability company and income taxes (benefits) accrued to the members.
Accordingly, no income taxes (benefits) were reflected in the accompanying
financial statements as of December 31, 1997 and for the period then ended.
Since converting from an LLC to a corporation in July 1998, the Company has
incurred net operating losses of $22,703,000. This loss will expire if not
utilized by December 31, 2018. As of December 31, 1998 a

valuation allowance for the full amount of the net deferred tax asset of
approximately $37,985,023, resulting from the tax net operating losses and other
items was recorded because of the uncertainty regarding its realization.
 
    The tax effects of temporary differences that give rise to significant
portions of deferred tax assets at December 31, 1998 are as follows:
 

1998 ------------- Equity based compensation.......................................................................... $ 25,267,265 Net operating loss carryforwards................................................................... 9,347,966 Start-up costs..................................................................................... 2,988,359 Other.............................................................................................. 381,433 ------------- Less valuation allowance........................................................................... (37,985,023) ------------- Deferred tax asset, net............................................................................ $ -- ------------- -------------

 

 

 
 
    The income tax benefit is different from the amount computed using
applicable statutory federal rates for the following reasons:
 

1998 ------------- Income tax benefit at federal statutory rate....................................................... $ 39,284,875 Adjustment due to: LLC status through July 31, 1998................................................................. (7,089,945) State taxes and other............................................................................ 5,790,093 Increase in valuation allowance.................................................................. (37,985,023) ------------- Income tax benefit................................................................................. $ -- ------------- -------------

 

 

 
 
    FEDERAL AIR TRANSPORTATION TAX--Currently, a Federal transportation tax is
imposed upon the sale of airline tickets and generally is collected by the
airlines selling the tickets. The tax is based upon a percentage of the cost of
transportation, which was 9% for periods prior to October 1, 1998 and 8%
thereafter. The tax has been calculated based on the amount paid to the airline
for a ticket, rather than the price paid by the customer. There is a possibility
that current law requires computation of the tax based on the price paid by the
customer. Approximately $111,000 in additional taxes relating to the method of
calculating the tax has been accrued as of December 31, 1998.
 
9. OTHER RELATED PARTY TRANSACTIONS
 
    The Founder and Vice Chairman of priceline.com also serves as non-executive
Chairman of NewSub Services, Inc. ("NewSub"), a direct marketing company
co-founded by him. The Company participates in certain adaptive marketing
programs with NewSub. Sales and marketing expense related to these programs
totaled $80,799 for the year ended December 31, 1998. There was no such expense
in 1997.
 
    In June 1998, priceline.com issued a promissory note to a Walker Digital for
$1,000,000. The promissory note bore interest at a rate of 6% per annum and was
due June 30, 1999. The note has been repaid.

10. COMMITMENTS AND CONTINGENCIES
 
    LEGAL PROCEEDINGS--On January 6, 1999, priceline.com received notice that a
third party patent applicant and patent attorney, Thomas G. Woolston,
purportedly had filed in December 1998 with the United States Patent and
Trademark Office a request to declare an "interference" between a patent
application filed by Woolston describing an electronic market for used and
collectible goods and priceline.com's core buyer-driven commerce patent.
Priceline.com has received a copy of a Petition for Interference from Woolston,
the named inventor of at least three United States Patent applications titled
"Consignment Nodes," one of which has issued as a patent. Priceline.com
currently is awaiting information from the Patent Office regarding whether it
will initiate an interference proceeding concerning Woolston's patent
application and priceline.com's core buyer-driven commerce patent. An
interference is an administrative proceeding instituted in the Patent Office to
determine questions of patentability and priority of invention between two or
more parties claiming the same patentable invention. There is no statutory
period within which the Patent Office must act on an interference request. If an
interference is declared and proceeds through a final hearing in the Patent
Office, a final judgment is made by the Patent Office as to inventorship.
Following such final judgment, appeals could be made in Federal court. While
there can be no certainty as to time periods, interference proceedings typically
take years to resolve.
 
    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from the
priceline.com core buyer-driven commerce patent. In order to make this showing,
he would have to prove, among other things, that he invented the subject matter
of the priceline.com claims before the inventors of the priceline.com patent. If
the Patent Office were to find that Woolston's patent application supported the
copied priceline.com claims, it would resolve the interference by awarding
inventorship to the party with the earliest proven date of invention. Woolston
recently announced an agreement to license his issued patent and pending patent
applications to the owner of an Internet travel service that, according to such
announcement, commenced on-line operations in the fourth quarter of 1998 and
purports to compete with priceline.com.
 
   
    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While Woolston claims to have an earlier
invention date by a period of approximately sixteen months, the final decision
as to priority of invention would be made by the Patent Office after considering
facts provided by each party during the interference proceeding. If an
interference is declared and thereafter resolved in favor of Woolston, such
resolution could result in an award of some or all of the disputed patent claims
to Woolston. If, following such award, Woolston were successful in a patent
infringement action against priceline.com, including prevailing over all
defenses available to priceline.com such as those of non-infringement and
invalidity, this could require priceline.com to obtain licenses from Woolston at
a cost which could significantly adversely affect priceline.com's business. If
Woolston prevailed in both an interference and an infringement action, then
priceline.com could be enjoined from conducting business through the
priceline.com service to the extent covered by the patent claims awarded to
Woolston. In addition, defense of the interference action may be expensive and
may divert management attention away from priceline.com's business.
    
 
    On January 19, 1999, Marketel International Inc. ("Marketel"), a California
corporation, filed a lawsuit against priceline.com and Priceline Travel, among
others. On February 22, 1999, Marketel filed an amended and supplemental
complaint. The amended complaint filed by Marketel alleges causes of action for,
among other things, misappropriation of trade secrets, breach of contract,
conversion, breach of confidential relationship, copyright infringement, fraud,
unfair competition and false advertising, and seeks

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

injunctive relief and damages in an unspecified amount. In its amended
complaint, Marketel alleges, among other things, that the defendants conspired
to misappropriate Marketel's business model, which it describes as a
buyer-driven electronic marketplace for travel services and its appurtenant
techniques, market research, forms, plans, and processes, which allegedly were
provided in confidence approximately ten years ago. The amended complaint also
alleges that three former Marketel employees are the actual sole inventors or
co-inventors of a patent which was issued on August 11, 1998 and which patent
has been assigned to priceline.com. Marketel asks that the patent's inventorship
be corrected accordingly.
 
    Based upon publicly available information, priceline.com believes that
Marketel's fax and fee-based business was launched in 1991 and ceased operations
seven months later. Priceline.com's Internet-based model was independently
developed by Walker Digital and priceline.com, and practiced by the Company
starting in 1998. Based on publicly available information and Marketel's
complaint, priceline.com understands that Marketel operated a fax-based travel
information service which offered consumers, travel agents and/or consolidators
the opportunity to purchase specially printed forms. These forms, when
accompanied by an additional non-refundable fee, allowed prospective ticket
buyers to fax to Marketel credit-card guaranteed bids for airline travel at a
bid price specified by the buyer. The Company believes that Marketel has not
engaged in any regular commercial activities since ceasing operations in 1992.
Based upon publicly available information, Marketel reactivated its active
status as a corporation by satisfying its back-due tax obligations to the State
of California shortly after the filing of its complaint.
 
    On February 5, and February 10, 1999, the Company filed their answer and
amended answer, respectively, to the amended complaint, in which they denied the
material allegations of liability in the complaint. Priceline.com and all other
defendants strongly dispute the material legal and factual allegations contained
in Marketel's amended complaint and believe that the amended complaint is
without merit. Priceline.com intends to defend vigorously against the action.
Defending the law suit may involve significant expense and, due to the inherent
uncertainties of litigation, there can be no certainty as to the ultimate
outcome. Pursuant to the indemnification obligations contained in the Purchaser
and Intercompany Services Agreement with Walker Digital, Walker Digital has
agreed to indemnify, defend and hold harmless priceline.com for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.
 
    From time to time the Company has been and expects to continue to be subject
to legal proceedings and claims in the ordinary course of business, and
including claims of alleged infringement of third party intellectual property
rights by the company. Such claims, even if not meritorious, could result in the
expenditure of significant financial and managerial resources.
 
    AIRLINE ALLIANCES AND RELATIONSHIPS--Priceline.com has entered into Airline
Participation Agreements with eighteen airlines for the supply of airline
tickets. The Airline Participation Agreements do not commit the airlines to
provide tickets for any particular routes or at a discount to their retail
prices, but outline the terms and conditions under which tickets may be sold
pursuant to fares, rules and availability that the airlines may provide from
time to time. The Airline Participation Agreements are generally subject to
termination upon 30 days notice by priceline.com or the airline.
 
    EMPLOYMENT CONTRACTS--Priceline.com has entered into employment agreements
with certain members of senior management that provide for minimum annual
compensation of approximately $2,135,000 in the aggregate. The agreements
provide for periods of employment of up to 3 years. Generally, the agreements
provide for incentives and bonuses based on the achievement of performance
goals, as well as the grant of stock options under the 1997 Omnibus Stock Option
Plan.

    CAPITAL LEASES--Priceline.com leases certain machinery and equipment costing
$74,711 under a capital lease agreement. Accumulated depreciation on this
equipment was $2,075 and $26,979 at December 31, 1997, and December 31, 1998,
respectively. These amounts are included in property and equipment in Note 4.
 
    Future minimum lease payments, including interest, under the capital lease
at December 31, 1998 are as follows:
 

YEAR ENDING DECEMBER 31, 1999................................................................................................... $ 30,389 2000................................................................................................... 30,389 --------- Total minimum lease payments........................................................................... 60,778 Less amounts representing interest..................................................................... 9,671 --------- Present value of future minimum lease payments......................................................... 51,107 Less current portion of obligations.................................................................... 25,033 --------- Obligations under capital leases, net of current portion............................................... $ 26,074 --------- ---------

 

 

 
 
11. BENEFIT PLAN
 
    Priceline.com adopted a defined contribution 401(k) savings plan (the
"Plan") during 1998 covering all employees who are at least 21 years old and
have completed 6 months of service. The Plan allows eligible employees to
contribute up to 20% of their eligible earnings, subject to a statutorily
prescribed annual limit. The Company may make matching contributions on a
discretionary basis to the Plan. All participants are fully vested in their
contributions and investment earnings. During the year ended December 31, 1998,
the Company did not make any matching contributions to the Plan.
 
12. SUBSEQUENT EVENTS
 
   
    On March 25, 1999, the Company obtained shareholder approval of a 1.25 for 1
stock split of its common stock and an increase in the authorized shares of its
common stock to 1,000,000,000 shares. In conjunction with the stock split the
par value of the common stock was reduced from $.01 per share to $.008 per
share. All share and per share data have been retroactively adjusted to reflect
the stock split.
    
 
   
    On March 24, 1999, priceline.com exercised its call option to purchase
Priceline Travel for nominal consideration and Priceline Travel was merged into
priceline.com.
    
 
    On March 3, 1999, Capital One Bank notified the Company of its termination
of its adaptive marketing program effective May 1, 1999.
 
13. RESTATEMENT
 
    Subsequent to the issuance of the Company's combined 1998 financial
statements, the Company's management determined that the calculation of the fair
value of the Delta warrant, other airline warrants and the beneficial conversion
feature on the Series B Preferred Stock should be revised. The fair value of the
Delta warrant and the other airline warrants has been revised to reflect the
change in the volatility assumption from 50% to 132%, eliminate the "large
block" and lack of marketability discounts, and consider the warrant's
anti-dilution and exercisability features. As a result, the 1998 combined
financial statements have been restated from the amounts previously reported to
recognize an additional $22.0 million of expense based upon the revised fair
value of the warrants at December 31, 1998, of which

             PRICELINE.COM INCORPORATED AND PRICELINE TRAVEL, INC.
 
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
13. RESTATEMENT (CONTINUED)
   
$3.0 million is included in the cost of revenues-supplier warrant costs and
$19.0 million is included in expenses-supplier start-up warrant costs. In
addition, the value of the beneficial conversion feature on the Series B
Preferred Stock has been revised to calculate such amount based on 22,500,000
shares. As a result, additional paid-in capital and accumulated deficit have
been restated from amounts previously reported to recognize an additional
$883,424 of accretion of preferred stock based on the revalued beneficial
conversion feature.
    
 
    A summary of the significant effects of the restatement is as follows:
 

AS PREVIOUSLY REPORTED AS RESTATED -------------- --------------- At December 31, 1998: Additional paid-in capital................................ $ 148,224,070 $ 171,155,186 Accumulated deficit.......................................

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
   
    Section 145 of the Delaware General Corporation Law authorizes a
corporation's board of directors to grant indemnity to directors and officers in
terms sufficiently broad to permit such indemnification under certain
circumstances for liabilities, including reimbursement for expenses incurred,
arising under the Securities Act of 1933.
    
 
    As permitted by Delaware law, Article Seventh of priceline.com's certificate
of incorporation provides that (1) priceline.com is required to indemnify its
directors and officers to the fullest extent permitted by Delaware law, subject
to certain very limited exceptions; (2) priceline.com is permitted to indemnify
its other employees to the extent that it indemnifies its officers and
directors, unless otherwise required by law, its certificate of incorporation,
its by-laws or agreements; (3) priceline.com is required to advance expenses, as
incurred, to its directors and officers in connection with a legal proceeding to
the fullest extent permitted by Delaware law, subject to certain very limited
exceptions; and (4) the rights conferred in the certificate of incorporation are
not exclusive. As permitted by Delaware law, priceline.com's certificate of
incorporation includes a provision that eliminates the personal liability of its
directors for monetary damages for breach of fiduciary duty as a director,
except for liability (1) for any breach of the director's duty of loyalty to
priceline.com or its stockholders; (2) for acts of omissions not in good faith
or that involve intentional misconduct or a knowing violation of law; (3) under
Section 174 of Delaware General Corporation Law regarding payments of dividends,
stock purchases or redemptions which are unlawful; or (4) for any transaction
from which the director derived an improper personal benefit. This provision in
the certificate of incorporation does not eliminate the directors' fiduciary
duty, and in appropriate circumstances equitable remedies such as injunctive or
other forms of non-monetary relief will remain available under Delaware law. In
addition, each director will continue to be subject to liability for breach of
the director's duty of loyalty to priceline.com for acts or omissions not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
unlawful under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.
 
                                      II-1
 
    As permitted by Delaware law, priceline.com has purchased insurance covering
the company's directors and officers against liability asserted against them in
their capacity as such. Reference is made to the Underwriting Agreement
contained in Exhibit 1.1 hereto, which contains provisions indemnifying officers
and directors of priceline.com against certain liabilities.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
    Since its inception, priceline.com has issued and sold the following

ITEM 17. UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned Registrant hereby undertakes that:
 
(1) For purposes of determining any liability under the Securities Act, the
    information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon rule 430A and contained in a form of
    Prospectus filed by the Registrant pursuant to Rule 424(b)(1) of (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
(2) For the purposes of determining any liability under the Securities Act, each
    post-effective amendment that contains a form of prospectus shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.

Stamford, State of Connecticut, on March 26, 1999.

      2. AGREEMENTS TO SELL AND PURCHASE. Upon the basis of the representations

stated, the Company hereby agrees to sell to the several Underwriters, and each
Underwriter agrees, severally and not jointly, to purchase from the Company the

      On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to sell
to the Underwriters the Additional Shares, and the Underwriters shall have a
one-time option to purchase, severally and not jointly, up to 1,500,000
Additional Shares at the Purchase Price. If the Representatives, on behalf of
the Underwriters, elect to exercise such option, the Representatives shall so
notify the Company in writing not later than 30 days after the date of this

purchased by the Underwriters and the date on which such shares are to be

                                       9
 
 
purchased as provided in Section 4 hereof solely for the purpose of covering
over-allotments made in connection with the offering of the Firm Shares. If any
Additional Shares are to be purchased, each Underwriter agrees, severally and
not jointly, to purchase the number of Additional Shares (subject to such
adjustments to eliminate fractional shares as the Representatives may determine)
that bears the same proportion to the total number of Additional Shares to be
purchased as the number of Firm Shares set forth in Schedule I hereto opposite
the name of such Underwriter bears to the total number of Firm Shares.
 
      The Company hereby agrees that, without the prior written consent of
Morgan Stanley on behalf of the Underwriters, it will not, during the period
ending 180 days after the date of the Prospectus, (i) file a registration
statement relating to an offering of shares of Common Stock (other than a
registration statement on Form S-8 covering shares of Common Stock subject to
options under the Company's 1997 Omnibus Plan or 1999 Omnibus Plan); (ii) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (iii) enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic consequences
of ownership of the Common Stock, whether any such transaction described in
clause (ii) or (iii) above is to be settled by delivery of Common Stock or such
other securities, in cash or otherwise. The foregoing sentence shall not apply
to (A) the Shares to be sold hereunder; (B) the issuance by the Company of
shares of Common Stock upon the exercise of an option or warrant or the

employee benefit plans, provided the recipients of such stock agree to be bound
by the above terms; (E) the issuance of performance warrants (or shares of
capital stock on exercise of such warrants) to suppliers or other entities
providing products or services to the Company in connection with entering into
certain supply, adaptive marketing or other similar arrangements, provided that
the recipient of such warrants or shares agrees to be bound by the above terms
or (F) the filing of a Rule 462 Registration Statement.

Statement and each person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Underwriter,
but only with reference to information relating to such Underwriter furnished to
the Company in writing by such Underwriter through you expressly for use in the
Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.
 
      (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to Section 7(a) or 7(b), such person (the "INDEMNIFIED PARTY")
shall promptly notify the person against whom such indemnity may be sought (the
"INDEMNIFYING PARTY") in writing and the indemnifying party, upon request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred
 
 
                                       18
 
 
upon receipt of reasonably detailed invoices thereof. Such firm shall be
designated in writing by Morgan Stanley in the case of parties indemnified
pursuant to Section 7(a), and by the Company, in the case of parties indemnified
pursuant to Section 7(b). The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.
 
      (d) To the extent the indemnification provided for in Section 7(a) or 7(b)
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then each indemnifying party
under such paragraph, in lieu of indemnifying such indemnified party thereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other hand from the offering of the Shares
or (ii) if the allocation provided by clause 7(d)(i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause 7(d)(i) above but also the relative
fault of the Company on the one hand and of the Underwriters on the other hand
in connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other hand in connection with the offering of the
Shares shall be deemed to be in the same respective proportions as the net
proceeds from the offering of the Shares (before deducting expenses) received by
the Company and the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover of the
Prospectus, bear to the aggregate Public Offering Price of the Shares. The
relative fault of the Company on the one hand and the Underwriters on the other
hand shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Underwriters' respective obligations to contribute
 
 
                                       19
 
 
pursuant to this Section 7 are several in proportion to the respective number of
Shares they have purchased hereunder, and not joint.
 
      (e) The Company and the Underwriters agree that it would not be just or
equitable if contribution pursuant to this Section 7 were determined by PRO RATA
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in Section 7(d). The amount paid or payable
by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 7, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 7 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.
 
      (f) The indemnity and contribution provisions contained in this Section 7
and the representations, warranties and other statements of the Company
contained in this Agreement shall remain operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made
by or on behalf of any Underwriter or any person controlling any Underwriter or
by or on behalf of the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Shares.
 
      8. DIRECTED SHARE PROGRAM INDEMNIFICATION. (a) The Company agrees to
indemnify and hold harmless Morgan Stanley and each person, if any, who controls
Morgan Stanley within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act ("Morgan Stanley Entities"), from and against any
and all losses, claims, damages and liabilities (including, without limitation,
any legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) (i) caused by any untrue statement or
alleged untrue statement of a material fact contained in any material prepared
by or with the consent of the Company for distribution to Participants in
connection with the Directed Share Program, or caused by any omission or 
 
 
                                       20
 
 
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statement therein; (ii) caused by the failure of any
Participant to pay for and accept delivery of Directed Shares that the
Participant agreed to purchase; or (iii) related to, arising out of, or in
connection with the Directed Share Program, other than losses, claims, damages
or liabilities (or expenses relating thereto) that are finally judicially
determined to have resulted from the bad faith or gross negligence of Morgan
Stanley Entities.
 
     (b) In case any proceeding (including any governmental investigation) shall
be instituted involving any Morgan Stanley Entity in respect of which indemnity
may be sought pursuant to Section 8(a), the Morgan Stanley Entity seeking
indemnity, shall promptly notify the Company in writing and the Company, upon
request of the Morgan Stanley Entity, shall retain counsel reasonably
satisfactory to the Morgan Stanley Entity to represent the Morgan Stanley Entity
and any others the Company may designate in such proceeding and shall pay the
fees and disbursements of such counsel related to such proceeding. In any such
proceeding, any Morgan Stanley Entity shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Morgan Stanley Entity unless (i) the Company shall have agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the Company and the Morgan
Stanley Entity and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. The
Company shall not, in respect of the legal expenses of the Morgan Stanley
Entities in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Morgan Stanley Entities. Any such
separate firm for the Morgan Stanley Entities shall be designated in writing by
Morgan Stanley. The Company shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Company agrees to
indemnify the Morgan Stanley Entities from and against any loss or liability by
reason of such settlement or judgment. The Company shall not, without the prior
written consent of Morgan Stanley, effect any settlement of any pending or
threatened proceeding in respect of which any Morgan Stanley Entity is or could
have been a party and indemnity could have been sought hereunder by such Morgan
Stanley Entity, unless such settlement includes an unconditional release of the
Morgan Stanley Entities from all liability on claims that are the subject matter
of such proceeding.
 
     (c) To the extent the indemnification provided for in Section 8(a) is
unavailable to a Morgan Stanley Entity or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then the Company in lieu of
 
 
                                       21
 
 
indemnifying the Morgan Stanley Entity thereunder, shall contribute to the
amount paid or payable by the Morgan Stanley Entity as a result of such losses,
claims, damages or liabilities (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and the
Morgan Stanley Entities on the other hand from the offering of the Directed
Shares or (ii) if the allocation provided by clause 8(c)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 8(c)(i) above but also the
relative fault of the Company on the one hand and of the Morgan Stanley Entities
on the other hand in connection with any statements or omissions that resulted
in such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Morgan Stanley Entities on the other hand in connection with
the offering of the Directed Shares shall be deemed to be in the same respective
proportions as the net proceeds from the offering of the Directed Shares (before
deducting expenses) and the total underwriting discounts and commissions
received by the Morgan Stanley Entities for the Directed Shares, bear to the
aggregate Public Offering Price of the Directed Shares. If the loss, claim,
damage or liability is caused by an untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact, the
relative fault of the Company on the one hand and the Morgan Stanley Entities on
the other hand shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement or the omission or alleged omission
relates to information supplied by the Company or by the Morgan Stanley Entities
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.
 
      (d) The Company and the Morgan Stanley Entities agree that it would not be
just or equitable if contribution pursuant to this Section 8 were determined by
PRO RATA allocation (even if the Morgan Stanley Entities were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in Section 8(c). The amount
paid or payable by the Morgan Stanley Entities as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by the Morgan Stanley
Entities in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, no Morgan Stanley Entity shall
be required to contribute any amount under this Section 8 in excess of the
amount by which the total price at which the Directed Shares distributed to the
public were offered to the public exceeds the amount of any damages that such
Morgan Stanley Entity has otherwise been required to pay. The remedies provided
for in this Section 8
 
 
                                       22
 
 
are not exclusive and shall not limit any rights or remedies which may otherwise
be available to any indemnified party at law or in equity.
 
      (e) The indemnity and contribution provisions contained in this Section 8
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Morgan Stanley Entity or the Company, its officers or directors or any
person controlling the Company and (iii) acceptance of and payment for any of
the Directed Shares.
 
      9. TERMINATION. This Agreement shall be subject to termination by notice
given by you to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited on or by, as the case may be, either the New
York Stock Exchange, the American Stock Exchange or the NASD, (ii) trading of
any securities of the Company shall have been suspended on any exchange or in
any over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in your judgment, is material and adverse and (b) in the case of any of
the events specified in clauses 9(a)(i) through 9(a)(iv), such event, singly or
together with any other such event, makes it, in your judgment, impracticable to
market the Shares on the terms and in the manner contemplated in the Prospectus.
 
      10. EFFECTIVENESS; DEFAULTING UNDERWRITERS. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.
 
      If, on the Closing Date or the Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase Shares that
it has or they have agreed to purchase hereunder on such date, and the aggregate
number of Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of the Shares to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the number of Firm Shares set forth
opposite their respective names in Schedule I bears to the aggregate number of
Firm Shares set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as you may specify, to purchase the
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase on such date; PROVIDED that in no event shall the number of
Shares that any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 10 by an amount in excess of one-ninth of
such number of
 
 
                                       23
 
 
Shares without the written consent of such Underwriter. If, on the Closing Date,
any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and
the aggregate number of Firm Shares with respect to which such default occurs is
more than one-tenth of the aggregate number of Firm Shares to be purchased, and
arrangements satisfactory to you and the Company for the purchase of such Firm
Shares are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of any non-defaulting Underwriter or the
Company. In any such case either you or the Company shall have the right to
postpone the Closing Date, but in no event for longer than seven days, in order
that the required changes, if any, in the Registration Statement and in the
Prospectus or in any other documents or arrangements may be effected. If, on the
Option Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Additional Shares and the aggregate number of Additional Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Additional Shares to be purchased, the non-defaulting Underwriters
shall have the option to (i) terminate their obligation hereunder to purchase
Additional Shares or (ii) purchase not less than the number of Additional Shares
that such non-defaulting Underwriters would have been obligated to purchase in
the absence of such default. Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement.
 
      If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.
 
      11. COUNTERPARTS. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.
 
      12. APPLICABLE LAW. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York.
 
      13. HEADINGS. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

Dear Sirs and Mesdames:
 
      The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") and Morgan Stanley & Co. International Limited ("MSIL")
propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT")
with priceline.com Incorporated, a Delaware corporation (the "COMPANY")
providing for the public offering (the "PUBLIC OFFERING") by the several
underwriters, including Morgan Stanley and MSIL (the "UNDERWRITERS") of shares
(the "SHARES") of the Common Stock (par value $.01 per share) of the Company
(the "COMMON STOCK").
 
      To induce the Underwriters that may participate in the Public Offering to
continue their efforts in connection with the Public Offering, the undersigned
 
 
                                       27
 
 
hereby agrees that, without the prior written consent of Morgan Stanley on
behalf of the Underwriters, it will not, during the period commencing on the
date hereof and ending 180 days after the date of the final prospectus relating
to the Public Offering (the "PROSPECTUS"), (1) offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, lend, or otherwise
transfer or dispose of, directly or indirectly, any shares of Common Stock or
any securities convertible into or exercisable or exchangeable for Common Stock
or (2) enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of the Common
Stock, whether any such transaction described in clause (1) or (2) above is to
be settled by delivery of Common Stock or such other securities, in cash or
otherwise. In addition, the undersigned agrees that, without the prior written
consent of Morgan Stanley on behalf of the Underwriters, it will not, during the
period commencing on the date hereof and ending 180 days after the date of the
Prospectus, make any demand for or exercise any right with respect to, the
registration of any shares of Common Stock or any security convertible into or
exercisable or exchangeable for Common Stock.
 
      The foregoing provisions shall not apply to the sale or other transfer of
shares of Common Stock by the undersigned to any associate (as such term is
defined in Rule 12b-2 of the Securities Exchange Act of 1934) of the
undersigned; PROVIDED THAT, prior to any such sale or other transfer of shares
of Common Stock, any such associated transferee agrees in writing to the
restrictions on transfer set forth herein.
 
      Whether or not the Public Offering actually occurs depends on a number of
factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters. In the event that the
Public Offering shall not have been consummated on or before May 15, 1999, this
Lock-Up Agreement shall be of no further force or effect.

Dear Sirs and Mesdames:
 
      The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") and Morgan Stanley & Co. International Limited ("MSIL")
propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT")
with priceline.com Incorporated, a Delaware corporation (the "COMPANY")

Offering (the "PROSPECTUS"), (1) offer, pledge, sell, contract to sell, sell any
