                               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 who determine whether to accept the
customer's offer, 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 to enable priceline.com to
fulfill their offers from inventory provided by participating sellers. 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
determine whether to fulfill a customer's offer based upon the available fares,
rules and inventory that have been provided by participating sellers in their
private data bases. Upon completion of a successful transaction, 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, a customer's offer
is submitted directly to the participating sellers who determine whether to
fulfill the offer. For these 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.
    
 
   
    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 134,878 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. We
believe that the priceline.com service already has achieved significant consumer
acceptance and widespread brand awareness.

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 $48.2 million during the period from July 18,
1997 (inception) through December 31, 1998, before giving effect to $45.8
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 $94.0 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.
    
 
                                       2
<PAGE>
   
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 with
high gross 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 a third party credit card issuer for qualifying credit card
applications submitted over the priceline.com service in connection with
customer offers for airline tickets. We expect that revenues attributable to our
adaptive marketing programs will increase significantly in future periods.
Because the fees generated by our adaptive marketing program have high gross
margins, adaptive marketing revenues have a disproportionate impact on our total
gross margin. We experienced a positive total gross profit for the year ended
December 31, 1998 due primarily to the contribution of our adaptive marketing
programs to our revenues. We expect that, in the future, a substantial portion
of our gross profit will continue to be attributable to our adaptive marketing
programs.
    
 
   
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 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
    
 
                                       3
<PAGE>
   
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 agreements with 18 airlines for the supply of
airline tickets. However, these 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
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.
    
 
                                       4
<PAGE>
   
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
 
    - 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
    
 
                                       5
<PAGE>
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.
    
 
   
    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 approximately     % 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 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.
 
                                       6
<PAGE>
   
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 141 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.
    
 
   
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.
    
 
   
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.
    
 
                                       8
<PAGE>
   
    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.
    
 
   
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
    
 
                                       9
<PAGE>
   
one Internet travel services 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 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 the 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.
    
 
   
    We believe that Woolston's claim is without merit. Among other things, we
believe that the Woolston 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, in addition to prevailing in both an interference and
an infringement action, Woolston were able to make the showings necessary to
obtain an injunction, 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
    
 
                                       10
<PAGE>
   
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 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,
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 to purchase 50,000 shares of our
common stock. The 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 injunctive relief and
damages in an unspecified amount. In its 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.
    
 
   
    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 by Walker Digital
and practiced by priceline.com starting in 1998. Based on publicly available
information and Marketel's 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 its complaint.
    
 
   
    On February 5, 1999, the defendants filed their answer to the complaint, in
which they denied the material allegations of liability in the complaint. We and
all other defendants strongly dispute the material legal and factual allegations
contained in Marketel's complaint and believe that the complaint is without
merit. We intend 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.
    
 
    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.
    
 
                                       11
<PAGE>
    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.

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;
 
                                       13
<PAGE>
    - 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;
    
 
   
    - 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 are presently held by Priceline Travel. To the extent that
such registrations can be transferred by merger, we intend to succeed to all
such registrations by merging with Priceline Travel prior to the consummation of
this offering. We expect to obtain all other required travel related
registrations prior to the consummation of this offering.
 
                                       14
<PAGE>
    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
 
                                       15

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.
    
 
                                       16
<PAGE>
    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. Currently, we
do not pay any such taxes. 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, will beneficially
own approximately    and       percent (      and       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
    
 
                                       17
<PAGE>
   
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       shares of common stock
(    shares if the underwriters' over-allotment option is exercised in full),
and we will have reserved an additional   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   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 115,329,306
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 19,100,000
shares of common stock reserved for issuance under the 1997 Omnibus Plan and
7,500,000 shares of common stock reserved for issuance under the 1999 Omnibus
Plan; such registration statement will automatically become effective upon
filing. Of the number of shares subject to outstanding options at February 12,
1999, 8,407,792 options have vested as of such date. However, none of the
options issued or to be issued pursuant to the 1997 Omnibus Plan or the 1999
Omnibus Plan are exercisable 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 million additional 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
    
 
                                       18
<PAGE>
   
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 $
million (approximately $  million, if the Underwriters' over-allotment option is
exercised in full) at an assumed initial public offering price of $  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 $  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.

                                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
shares of common stock offered hereby are estimated to be approximately $
million (approximately $      million, if the underwriters' over-allotment
option is exercised in full), assuming an initial public offering price of $
per share and after deducting estimated offering expenses of $    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.

                                    DILUTION
 
   
    The pro forma net tangible book value of priceline.com as of December 31,
1998 was $  , or $  per share. "Pro forma net tangible book value per share" is
determined by dividing the pro forma number of outstanding 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     shares of
common stock offered hereby at an assumed initial public offering price of $
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 $  , or $  per share. This
represents an immediate increase in pro forma net tangible book value of $  per
share to existing stockholders and an immediate dilution of $  per share to new
investors purchasing shares at the initial public offering price. The following
table illustrates the per share dilution:

                      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

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 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 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 February 12, 1999 priceline.com had 141 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.
    
 
   
    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 and hotel reservation services, revenues are generated by transactions
with customers who make offers to purchase airline tickets and reserve hotel
    
 
                                       24
<PAGE>
   
rooms supplied by participating sellers. Offers are guaranteed by a customer
credit card. Revenues and related costs are recognized if, and when, the
customer's offer is accepted. 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 may also include fees from
third parties for adaptive marketing programs.
    
 
   
    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 134,878 airline tickets, representing
approximately $30.4 million in revenue. Priceline.com believes that its offer
fulfillment rate for airline tickets has been constrained 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 test 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 currently 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.
    
 
   
    Since its inception, priceline.com has incurred net losses in each fiscal
quarter. Priceline.com incurred net losses of $48.2 million during the period
from July 18, 1997 (inception) through December 31, 1998, before giving effect
to $45.8 million of non-cash charges arising from equity issuances to a number
of our 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 $94.0 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; Difficulty in Predicting Results of Operations."
    
 
   
    For the year ended December 31, 1998, priceline.com recorded aggregate
non-cash charges of $45.8 million. Of this amount, $6.5 million related to the
issuance of 6,500,000 shares of common stock to Mr. Richard S. Braddock, the
Chairman and Chief Executive Officer of priceline.com and $39.3 million related
to the issuance of an aggregate of 15,795,522 warrants to purchase common stock,
including 15,645,522 warrants issued to a number of our participating airlines.
    
 
   
    In August 1998, priceline.com entered into a warrant agreement with Delta to
purchase up to 15,114,083 shares of common stock at an exercise price of
approximately $1.16 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
    
 
                                       25
<PAGE>
   
warrant at 14,895,522. The amended warrant issued to Delta will vest 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 $38.1 million reflecting the fair value
of the Delta warrant on December 31, 1998.
    
 
   
    Priceline.com's travel agency license is held by Priceline Travel, a
separate company owned by Mr. Jay S. Walker, priceline.com's Founder and Vice
Chairman, and all of its airline ticket sales have been effected through
Priceline Travel, which will be merged with and into priceline.com prior to the
consummation of this offering. Accordingly, the financial statements of
Priceline Travel are presented on a combined basis with priceline.com for all
relevant periods.
    
 
   
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.
    
 
   
    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, substantially all of which were
attributable to priceline.com's third-party credit card marketing program.
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
    
 
   
    Cost of revenues for the year ended December 31, 1998 totaled $33.5 million.
Cost of revenues represents 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. Gross
profit, which is comprised of revenues less cost of revenues, was $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 have high gross
margins, adaptive marketing revenues had a significant impact on priceline.com's
total gross margin. Priceline.com experienced a positive total gross profit for
the year ended December 31, 1998, due primarily to the contribution of its
adaptive marketing programs to its gross profit. Priceline.com expects that, in
the future, a substantial portion of its gross profit may continue to 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.
    
 
   
    OPERATING EXPENSES
    
 
   
    SUPPLIER START-UP CHARGES.  Supplier start up charges for the year ended
December 31, 1998 totaled $39.0 million, or 110.6% of revenues. Supplier start
up charges consist of a one-time 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. Priceline.com
anticipates that it will recognize additional supplemental start-up charges in
the amount of $438,500 in 1999 and $438,500 in 2000 in connection with
additional warrants issued to a participating airline in January 1999.

    SALES AND MARKETING.  Sales and marketing expenses for the year ended
December 31, 1998 totaled $24.4 million, or 69.3% of revenues. Approximately 50%
of sales and marketing expenses were comprised of radio and newspaper
advertising expenses. The balance was comprised of fees payable to a third party
service provider, which operates priceline.com's call center, credit card
"merchant" fees, 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 31.5% 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 an
equivalent number of shares of common stock.
    
 
   
    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.

</TABLE>
    
 
   
    Revenues increased in each quarter since the commencement of operations in
April 1998. The increase in each quarter is primarily due to the increase in
sales of airline tickets resulting from expanded inventory, improved fill rates
and an expanded customer base due to increased market awareness and
    
 
                                       27
<PAGE>
   
acceptance of the priceline.com service. In addition to the foregoing trends,
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 the
Company'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 increased each quarter in conjunction with increases in
total revenue. Cost of revenue is primarily associated with the amounts paid to
the Company's airline partners for airline tickets. Gross profit, which is
comprised of revenues less cost of revenues, has increased every quarter from
$(920,671) for the quarter ended June 30, 1998 to $2.3 million for the quarter
ended December 31, 1998. Gross profit margin has increased from (13.1)% during
the quarter ended June 30, 1998 to 12.1% during the quarter ended December 31,
1998. The increase in gross margins during the fourth quarter resulted primarily
from the contribution of adaptive marketing revenues which have high gross
margins and, consequently, a significant impact on total gross margins.
    
 
   
    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;
    
 
   
    - 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.
    
 
                                       28
<PAGE>
   
    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 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 50,000 shares of common stock at an exercise price of $1.00
per share. This loan expires on April 15, 2003 and bears interest at a rate of
6.0%.
    
 
   
    Prior to completion of the 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 6,500,000 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.
    
 
                                       29
<PAGE>
   
    Priceline.com had no material commitments for capital expenditures at
December 31, 1998 but expects such expenditures to be at least $5.0 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.
    
 
   
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 $24.7 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.
    
 
   
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
    
 
                                       30
<PAGE>
   
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. 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 18,050,375 non-qualified stock
options 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 $1.20 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.
    
 
   
    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
    
 
                                       31
<PAGE>
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.

                                    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 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 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 134,878 airline tickets, representing approximately $30.4
million in revenue. 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 over 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 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,
    
 
                                       33

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,
 
                                       34
<PAGE>
   
each of these forms of seller-driven commerce have 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.
    
 
   
    - 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
    
 
                                       35
<PAGE>
   
      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.
    
 
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.
    
 
                                       36
<PAGE>
   
      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 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
    
 
                                       37
<PAGE>
   
      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 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.
    
 
                                       38
<PAGE>
   
    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.
 
   
    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.
    
 
                                       39
<PAGE>
   
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;
    
 
   
    - 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;
    
 
                                       40
<PAGE>
   
    - 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 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 (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 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.
    
 
                                       41
<PAGE>
   
    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 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
    
 
                                       42
<PAGE>
   
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 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.
    
 
                                       43
<PAGE>
   
    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 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.
    
 
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
    
 
                                       44
<PAGE>
   
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; and
    
 
   
    - consumers must be willing to depart at any time after 6 a.m. and land any
      time before 10 p.m. of day on the requested dates. All offers must be
      guaranteed with a major credit card; and
    
 
   
    - consumers must be limited in their ability to make multiple offers with
      respect to the same travel itinerary.
    
 
   
    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
    
 
                                       45
<PAGE>
   
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 14,895,522 shares
of common stock at an exercise price of approximately $1.16 per share. The Delta
warrant will vest at the earlier of December 31, 2005, and 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 1,750,000 shares of common stock, comprised of warrants
to purchase 750,000 shares of common stock at an exercise price of $4.00 per
share and warrants to purchase 1,000,000 shares of common stock at an exercise
price of $8.00 per share. The warrants having an exercise price of $4.00 per
share become exercisable 210 days after the completion of this offering. With
respect to the warrants having an exercise price of $8.00 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 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.

<PAGE>
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
through affiliations with other e-commerce companies. Other large companies with
strong brand 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 five 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
    
 
                                       48
<PAGE>
   
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.
 
    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 are presently held by Priceline Travel.
To the extent that such registrations can be transferred by merger,
priceline.com intends to succeed to all such registrations by merging with
Priceline Travel prior to the consummation of this offering. Priceline.com
expects to obtain all other required travel related registrations prior to the
consummation of this offering.
    
 
    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
    
 
                                       49
<PAGE>
   
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
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 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.
    
 
   
    Priceline.com believes that Woolston's claim is without merit. Among other
things, priceline.com believes that the Woolston 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, in addition to prevailing in both an interference
and an infringement action, Woolston were able to make the showings necessary to
obtain an injunction, 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 the company'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 to purchase 50,000 shares
of our common stock. The 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 injunctive relief and
damages in an unspecified amount. In its 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.
    
 
   
    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 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, 1999, the defendants filed their answer to the 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 complaint and believe that the
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.
    
 
   
    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 141 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 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
19,100,000, subject to adjustment as provided therein. Of such number,
18,050,375 options covering shares of common stock were outstanding under the
1997 Omnibus Plan as of February 12, 1998. 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 7.5 million, 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
    
 
                                       58
<PAGE>
   
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
    
 
                                       59
<PAGE>
   
part of an option in the manner described above, subject to the availability of
common stock under the 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.

    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
    
 
                                       61
<PAGE>
   
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 7.5 million subject to
adjustment as provided in the 1999 Omnibus Plan. There is a 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 during the life
of the 1999 Omnibus Plan, 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.
    
 
                                       62
<PAGE>
   
    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
    
 
                                       63
<PAGE>
   
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.
    
 
                                       64
<PAGE>
   
    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.
    
 
EMPLOYMENT ARRANGEMENTS
 
   
    BRADDOCK EMPLOYMENT AGREEMENT.  Pursuant to an employment agreement, dated
as of August 15, 1998, between priceline.com and Mr. Richard S. Braddock, Mr.
Braddock serves as the Chairman and
    
 
                                       65
<PAGE>
   
Chief Executive Officer of priceline.com through August 15, 2001. While Mr.
Braddock devoted a majority of his working time to priceline.com following
commencement of his employment, he retained his position as non-executive
Chairman of True North Communications, Inc. until January 31, 1999. Mr. Braddock
now serves as the Chairman and Chief Executive Officer of priceline.com on a
full-time basis. Pursuant to an agreement in principle entered into July 23,
1998, by and between priceline.com and Mr. Braddock in anticipation of entering

determine. Each stockholder is entitled to one vote for each share of common
stock held on all matters submitted to a vote of stockholders. Cumulative voting
for the election of directors is not provided for in the priceline.com's
certificate of incorporation, which means that the holders of a majority of the
shares voted can elect all of the directors then standing for election. The

conversion or redemption. Upon the occurrence of a liquidation, dissolution or
winding-up, the holders of shares of common stock would be entitled to share

or series, and to fix the rights, preferences, privileges and restrictions
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
have the effect of decreasing the market price of the common stock and could
adversely affect the voting and other rights of the holders of common stock.

                 CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
                             TO NON-U.S. INVESTORS
    
 
   
INTRODUCTION
    
 
   
    The following is a summary of certain United States federal tax consequences
to non-U.S. investors of owning common stock. In this summary, "non-U.S.
investor" means a person or entity other than:
    
 
   
    - a citizen or resident of the United States;
    
 
   
    - a corporation, partnership or other entity created or organized in or
      under the laws of the United States or of any state;
    
 
   
    - an estate, the income of which is subject to United States federal income
      taxation regardless of its source; or
    
 
   
    - a trust, the administration of which is subject to the primary
      supervi-sion of a United States court and the control of all of the
      substantial decisions of which is within the authority of one or more
      United States persons.
    
 
   
    This summary does not address all of the federal tax considerations that may
be relevant to a non-U.S. investor in light of its particular circumstances or
to non-U.S. investors that may be subject to special treatment under federal tax
laws. Also, this summary does not discuss any aspects of state, local or foreign
taxation. This summary is based on current provisions of the Internal Revenue
Code, Treasury regulations, judicial opinions, published positions of the IRS
and other applicable authorities. These authorities are all subject to change,
possibly with retroactive effect. Each prospective non-U.S. investor should
consult its tax advisor with respect to the tax consequences of investing in the
common stock.
    
 
   
DIVIDENDS
    
 
   
    Dividends paid to a non-U.S. investor generally will be subject to
withholding of federal income tax at a 30% rate or such lower rate as may be
specified by an applicable income tax treaty. However, if the dividend is
effectively connected with the conduct of a trade or business of the non-U.S.
investor within the United States, the dividend will instead be taxed at
ordinary federal income tax rates on a net income basis. Further, if the
non-U.S. investor is a corporation, this effectively connected dividend income
may also be subject to an additional branch profits tax.
    
 
   
SALE OR OTHER DISPOSITION OF COMMON STOCK
    
 
   
    A non-U.S. investor generally will not be subject to federal income tax on
any gain recognized on the sale or other disposition of common stock, except in
the following circumstances:
    
 
   
    (1) The gain will be subject to federal income tax if it is effectively
       connected with a trade or business of the non-U.S. investor within the
       United States.
    
 
   
    (2) The gain will be subject to federal income tax if the non-U.S. investor
       is an individual who holds the common stock as a capital asset, is
       present in the United States for 183 or more days in the taxable year of
       the sale or other disposition, and either the individual has a "tax home"
       in the United States for federal income tax purposes or the gain is
       attributable to an office or other fixed place of business maintained by
       the individual in the United States.
    
 
   
    (3) The gain may be subject to federal income tax pursuant to federal income
       tax laws applicable to certain expatriates.
    
 
   
    (4) The gain may be subject to federal income tax if priceline.com is or has
       been during certain periods a "United States real property holding
       corporation" and the non-U.S. investor held, at any time during the
       five-year period ending on the date of disposition (or, if shorter, the
       non-U.S.
    
 
                                       75

       investor's holding period), more than 5 percent of the outstanding common
       stock. Priceline.com believes that it will not constitute a United States
       real property holding corporation immediately after the offering and does
       not expect to become a United States real property holding corporation;
       however, no assurance can be given in this regard.
    
 
   
BACKUP WITHHOLDING AND INFORMATION REPORTING
    
 
   
    DIVIDENDS.  United States backup withholding tax generally will not apply to
dividends paid to a non-U.S. investor at an address outside the United States.
Priceline.com must report annually to the IRS and to each non-U.S. investor the
amount of dividends paid to such investor and the amount, if any, of tax
withheld with respect to such dividends. This information may also be made
available to the tax authorities in the non-U.S. investor's country of
residence.
    
 
   
    SALE THROUGH A U.S. OFFICE OF A BROKER.  Upon the sale or other disposition
of common stock by a non-U.S. investor to or through a United States office of a
broker, the broker must backup withhold at a rate of 31% and report the sale to
the IRS, unless the investor certifies its foreign status under penalties of
perjury or otherwise establishes an exemption from backup withholding.
    
 
   
    SALE THROUGH A FOREIGN OFFICE OF A BROKER.  Upon the sale or other
disposition of common stock by a non-U.S. investor to or through a foreign
office of a United States broker or a foreign broker with certain types of
relationships with the United States, the broker is not required to backup
withhold. However, the broker must report the sale or other disposition to the
IRS unless the broker has documentary evidence in its files that the seller is a
non-U.S. investor and certain other conditions are met, or the holder otherwise
establishes an exemption.
    
 
   
    Backup withholding is not an additional tax. Amounts withheld under the
backup withholding rules are generally allowable as a refund or credit against
the non-U.S. investor's federal income tax liability, if any, provided, that the
required information is furnished to the IRS.
    
 
   
    Final United States Treasury regulations, effective for payments made after
December 31, 1999, may affect the procedures to be followed by a non-U.S.
investor in establishing such investor's foreign status for purposes of the
withholding, backup withholding and information reporting rules described in
this "Backup Withholding and Information Reporting" section. Prospective
non-U.S. investors should consult their tax advisors concerning such
regulations.
    
 
   
FEDERAL ESTATE TAXES
    
 
   
    Common stock owned or treated as owned by an individual who is not a citizen
or a "resident," which is specially defined for federal estate tax purposes, of
the United States at the time of death, will be included in such individual's
gross estate for federal estate tax purposes, unless an applicable estate tax
treaty provides otherwise.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Prior to this offering, there has been no market for the common stock, and
there can be no assurance that a significant public market for the common stock
will develop or be sustained after this offering. Future sales of substantial
amounts of common stock, including shares issued upon exercise of outstanding
options and warrants, in the public market after this offering could adversely
affect market prices prevailing from time to time and could impair
priceline.com's ability to raise capital through the sale of its equity
securities. Sales of substantial amounts of common stock of priceline.com in the
public market could adversely affect the prevailing market price and the ability
of priceline.com to raise equity capital in the future.
    
 
   
    Upon completion of this offering, priceline.com will have outstanding
shares of common stock, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding warrants and options, which as of February
12, 1999 were vested for an aggregate of 8,407,792 shares of common stock and
will vest for an additional 9,642,583 shares of common stock in the future. Of
these shares, the   shares of common stock sold in this offering will be freely
tradable without restriction under the Securities Act unless purchased by
"affiliates" of priceline.com as that term is defined in Rule 144 under the
Securities Act.
    
 
   
    Each of priceline.com and the directors, executive officers and certain
other stockholders 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, file a registration statement, in the case
      of priceline.com, 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 in clause (1) or (2)
      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 this paragraph do not apply to:
    
 
   
    - the sale of the shares to the underwriters in this offering;
    
 
   
    - the issuance 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; 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, of such person which agrees to be bound by the foregoing
      provisions.
    
 
   
    In addition, the shareholders 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. Beginning 180
days after the date of this prospectus, all     shares will be eligible for sale
in the public market, subject to certain timing, manner of sale and volume
limitations pursuant to Rule 144.
    
 
                                       77
<PAGE>
   
    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person, or persons whose shares are aggregated,
who has beneficially owned restricted shares for at least one year, including
the holding period of any prior owner except an affiliate, would be entitled to
sell within any three-month period a number of shares that does not exceed the
greater of (1) 1% of the number of shares of common stock then outstanding,
which will equal approximately   shares immediately after this offering, or (2)
the average weekly trading volume of the common stock during the four calendar
weeks preceding the filing of a Form 144 with respect to such sale. Sales under
Rule 144 also are subject to certain manner of sale provisions and notice
requirements and to the availability of current public information about
priceline.com. Under Rule 144(k), a person who is not deemed to have been an
affiliate of priceline.com at any time during the three months preceding a sale,
and who has beneficially owned the shares proposed to be sold for at least two
years, including the holding period of any prior owner except an affiliate, is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.
    
 
   
    Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with certain restrictions of Rule 144. Any employee, officer or
director of or consultant to priceline.com who purchased his or her shares
pursuant to a written compensatory plan or contract may be entitled to rely on
the resale provisions of Rule 701. Rule 701 permits affiliates to sell their
Rule 701 shares under Rule 144 without complying with the holding period
requirements of Rule 144. Rule 701 further provides that non-affiliates may sell
such shares in reliance on Rule 144 without having to comply with the holding
period, public information, volume limitation or notice provisions of Rule 144.
All holders of Rule 701 shares are required to wait until 90 days after the date
of this prospectus before selling such shares.
    
 
   
    Following consummation of this offering, priceline.com intends to file a
registration statement on Form S-8 under the Securities Act covering shares of
common stock subject to outstanding options under the 1997 Omnibus Plan and 7.5
million shares of common stock reserved for issuance under the 1999 Omnibus
Plan. Based on the number of shares subject to outstanding options at February
12, 1999 and currently reserved for issuance under such plan, such registration
statement would cover approximately 18,050,375 shares issuable on exercise of
the options of which 8,407,792 options have vested as of such date. Such
registration statement will automatically become effective upon filing.
Accordingly, 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 agreements expire. Also beginning 90 days
after the date of this offering, certain holders of shares of common stock will
be entitled to certain rights with respect to registration of such shares of
common stock for offer and sale to the public. However, under certain lock-up
agreements with the underwriters, such rights will not be able to be exercised
until 180 days after the date of this prospectus. See "Description of Capital
Stock -- Registration Rights."

      indirectly, any shares or distribute any prospectus relating to the shares

territory of Canada or to, or for the benefit of, any resident of any province
or territory of Canada in contravention of the securities laws thereof and that
any offer or sale of shares in Canada will be made only pursuant to an exemption

international underwriter has further represented that it has not offered or
sold, and has agreed not to offer or sell, directly or indirectly, in Japan or

notice containing substantially the same statement as is contained in this
sentence.
    
 
   
    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 $   a share under the public offering price. Any underwriter
may allow, and such dealers may reallow, a concession not in excess of $   a
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.
    
 
   
    Priceline.com has granted to the U.S. underwriters an option, exercisable
for 30 days from the date of this prospectus, to purchase up to an aggregate of
       additional shares of common stock at the public offering price set forth
on the cover page hereof, less underwriting discounts and commissions. The U.S.
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 U.S.
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 U.S. 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 U.S. underwriters in the preceding table. If the U.S. 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
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 offered by the underwriters to the general public on the
same basis as the other shares of common stock offered hereby.
    
 
   
    Priceline.com has applied for quotation of the common stock on the Nasdaq
National Market under the symbol "PCLN."
    
 
                                       81
<PAGE>
   
    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:
    
 
   
    - the sale of the shares to the underwriters;
    
 
   
    - the issuance by priceline.com 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; 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 which 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 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.
    
 
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 U.S. 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,
    
 
                                       82

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.
    
 
                                 LEGAL MATTERS

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.

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 who determine
whether to accept the customer's offer, 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 to
enable priceline.com to fulfill their offers from inventory provided by
participating sellers. 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.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
    
 
   
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 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 5,516,667 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.
    
 
   
    REVENUE RECOGNITION--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 and hotel reservation services, revenues are generated
by transactions with customers who make offers to purchase airline tickets and
hotel rooms supplied by participating sellers. Offers are guaranteed by a
customer credit card. Revenues and related costs are recognized if, and when,
the customer's offer is accepted. Because

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    
   
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 may also 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, 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.
    
 
   
    Approximately $4,037,000 of total revenues are attributable to adaptive
marketing programs for the year ended December 31, 1998.
    
 
   
    SUPPLIER START-UP CHARGES--Supplier start-up charges include equity based
compensation (comprised of warrants to purchase Common Stock to secure airline
alliances and relationships--see note 6). Such charges are expensed as incurred.
    
 
   
    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 merchant fees, compensation for the Company's sales and
marketing personnel. Such 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.
    
 
   
    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 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".
    
 
   
    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.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
    
 
   
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    
   
    During the period 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 17,288,684 shares and 13,837,500 shares,
respectively, and options and warrants to purchase 33,745,598 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 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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    
   
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.

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 promissory note, priceline.com
issued detachable warrants to purchase 50,000 common shares at $1.00 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.

    On July 18, 1997, priceline.com issued 34,392,169 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.
    
 
   
    Also, on July 18, 1997, priceline.com issued 5,516,667 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 6,500,000 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 $2.46 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 ($21,309,750) 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 $4.00 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 March 1998, priceline.com issued warrants to purchase 100,000 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 100,000 shares at $1 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 50,000 shares of
Common Stock at an exercise price of $1.00 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 15,114,083 shares of Common Stock at an
exercise price of approximately $1.16 per share ("Delta Warrant"). 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 Air Lines to eliminate the vesting contingencies and fix the number of
shares subject to the warrant at 14,895,522. The amended Delta Warrant will vest
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. Accordingly, the Company
recognized approximately $38.1 million of expense based upon the fair value of
the warrant on December 31, 1998 which is included in Supplier Start-up Charges
in the accompanying statement of operations.
    
 
   
    On December 31, 1998, priceline.com issued warrants to purchase 750,000
shares of Common Stock at an exercise price of $4.00 per share to three airlines
in exchange for services provided to the Company. Accordingly, the Company
recognized approximately $.9 million of expense based upon the fair value of the
warrants at December 31, 1998, which is included in Supplier Start-up Charges in
the accompanying statement of operations.
    
 
   
    On January 29, 1999, priceline.com issued warrants to an airline to purchase
1,000,000 shares of Common Stock at an exercise price of $8.00 per share. The
warrants become exercisable as follows, 50% on January 29, 2000 and 50% on
January 29, 2001. If the airline does not provide the specified services, 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.

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 19,100,000 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
aggregated $245,063.

</TABLE>
    
 
   
    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 $0.19 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 7,500,000 million 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

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 $24,658,093,
resulting from the tax net operating losses and other items was recorded because
of the uncertainty regarding its realization.

    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.

    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 (U.S. Patent Number:
5,845,265). 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.
    
 
   
    Priceline.com believes that Woolston's claim is without merit. Among other
things, priceline.com believes that the Woolston 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, in addition to prevailing in both an interference
and an infringement action, Woolston were able to make the showings necessary to
obtain an injunction, 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 the company's
business.
    
 
   
    On January 19, 1999, Marketel International Inc., a California corporation,
filed a lawsuit against priceline.com and Priceline Travel, among others. The
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 injunctive relief and damages in an unspecified
amount. In the complaint, Marketel alleges, among other things, that the
defendants conspired to misappropriate Marketel's business model for 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 Company strongly disputes the material legal and factual allegations
contained in the complaint, and believes the complaint is without merit. The
Company intends to defend the action vigorously. 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.
    
 
   
    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.

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.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
   
    Section 145 of the Delaware General Corporation Law authorizes a court to
award or 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.

    As permitted by Delaware law, priceline.com has purchased insurance covering

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.

         are hereby empowered to exercise all such powers and do all such acts
         and things as may be exercised or done by the Corporation, subject,

or in the By-Laws of the Corporation.

                  SEVENTH: The Corporation shall indemnify its directors and
officers to the fullest extent authorized or permitted by law, as now or
hereafter in effect, and such right to indemnification shall continue as to a
person who has ceased to be a director or officer of the Corporation and shall
inure to the benefit of his or her heirs, executors and personal and legal
representatives; PROVIDED, HOWEVER, that, except for proceedings to enforce
rights to indemnification, the Corporation shall not be obligated to indemnify
any director or officer (or his or her heirs, executors or personal or legal
representatives) in connection with a proceeding (or part thereof) initiated by
such person unless such proceeding (or part thereof) was authorized or consented
to by the Board of Directors of the Corporation. The right to indemnification
conferred by this Article SEVENTH shall include the right to be paid by the

                  Any repeal or modification of this Article SEVENTH shall not
adversely affect any rights to indemnification and to the advancement of
expenses of a director or officer of the Corporation existing at the time of
such repeal or modification with respect to any acts or omissions occurring

capital stock represented and entitled to vote thereat, voting as a single
class. Unless otherwise provided in the Certificate of Incorporation, and

of Directors, in its discretion, or the officer of the Corporation presiding at
a meeting of stockholders, in such officer's discretion, may require that any

examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall also be produced and kept

                  SECTION 11. STOCK LEDGER. The stock ledger of the Corporation

of the meeting of the stockholders as it shall deem appropriate. Except to the
extent inconsistent with such rules and regulations as adopted by the Board of
Directors, the chairman of any meeting of the stockholders shall have the right
and authority to prescribe such rules, regulations and procedures and to do all
such acts as, in the



                                       10

                  SECTION 5. QUORUM. Except as otherwise required by law or the
Certificate of Incorporation, at all meetings of the Board of Directors, a
majority of the entire Board of Directors shall constitute a quorum for the

Directors. If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to

provided in the Certificate of Incorporation, or these By-Laws, any action
required or permitted to be taken at any meeting of the Board of Directors or of
any committee thereof may be taken without a meeting, if all the members of the
Board of Directors or committee,



                                       13
<PAGE>

as the case may be, consent thereto in writing, and the writing or writings are

                  SECTION 7. MEETINGS BY MEANS OF CONFERENCE TELEPHONE. Unless
otherwise provided in the Certificate of Incorporation, members of the Board of
Directors of the Corporation, or any committee thereof, may participate in a
meeting of the Board of Directors or such committee by means of a conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a meeting
pursuant to this Section 7 shall constitute presence in person at such meeting.

                  SECTION 8. COMMITTEES. The Board of Directors may designate
one or more committees, each committee to consist of one or more of the
directors of the Corporation. The Board of Directors may designate one or more

disqualified member, the member or members thereof present at any meeting and
not disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any absent or disqualified member. Any committee,
to the extent permitted by law 



                                       14
<PAGE>

and provided in the resolution establishing such committee, shall have and may
exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the Corporation, and may authorize the
seal of the Corporation to be affixed to all papers which may require it. Each
committee shall keep regular minutes and report to the Board of Directors when
required.

                  SECTION 9. COMPENSATION. The directors may be paid their
expenses, if any, of attendance at each meeting of the Board of Directors and
may be paid a fixed sum for attendance at each meeting of the Board of Directors
or a stated salary as director, payable in cash or securities. No such payment
shall preclude any director from serving the Corporation in any other capacity
and receiving compensation therefor. Members of special or standing committees
may be allowed like compensation for attending committee meetings.

                  SECTION 10. INTERESTED DIRECTORS. No contract or transaction
between the Corporation and one or more of its directors or officers, or between
the Corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers or have a financial interest, shall be void or voidable solely for this
reason, or solely because the director or officer is present at or participates
in the meeting of the Board of Directors or committee thereof which authorizes
the contract or transaction, or solely because the director or officer's vote is
counted for such purpose if (i) the material 




                                       15
<PAGE>

facts as to the director or officer's relationship or interest and as to the
contract or transaction are disclosed or are known to the Board of Directors or
the committee, and the Board of Directors or committee in good faith authorizes
the contract or transaction by the affirmative votes of a majority of the
disinterested directors, even though the disinterested directors be less than a
quorum; or (ii) the material facts as to the director or officer's relationship
or interest and as to the contract or transaction are disclosed or are known to
the stockholders entitled to vote thereon, and the contract or transaction is
specifically approved in good faith by vote of the stockholders; or (iii) the
contract or transaction is fair as to the Corporation as of the time it is
authorized, approved or ratified by the Board of Directors, a committee thereof
or the stockholders. Common or interested directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee which authorizes the contract or transaction.

                  SECTION 11. EX OFFICIO MEMBERS OF THE BOARD OF DIRECTORS. The
Board of Directors, in its discretion, may appoint one or more persons as ex
officio members of the Board of Directors, who shall serve at the pleasure of
the Board of Directors. Ex officio members of the Board of Directors shall be
permitted to attend meetings of the Board of Directors but shall not be entitled
to vote on any matter before the Board of Directors and shall not be considered
to be directors of the Corporation for any other purpose, including without
limitation, for establishing a 



                                       16
<PAGE>

quorum, acting by written consent or providing notice of meetings.
Notwithstanding the foregoing, the Board of Directors may hold meetings that do
not include ex officio members of the Board of Directors.

securities and which, as the owner thereof, the Corporation might have exercised

and the Corporation does not have a President, the Chief Executive Officer shall
be deemed to be the President of the Corporation and shall have the authority to
execute such document. In the absence or disability of the Chairman and the Vice
Chairman, or if there be none, the Chief Executive Officer shall preside at all

and special meetings of the Board of Directors, and if there be no Assistant

have custody of the seal of the Corporation and the Secretary or any Assistant
Secretary, if there be one, shall have authority to affix the same to any
instrument requiring it and when so affixed, it may be attested by the signature

of Directors may give general authority to any other officer to affix the seal
of the Corporation and to attest to the affixing by such officer's signature.

as if such person were such officer, transfer agent or registrar at the date of

the making of an affidavit of that fact by the person claiming the certificate

stock records of the Corporation by an entry showing from and to whom
transferred.

                                       27
<PAGE>

date has been fixed by the Board of Directors, the record date for determining
stockholders entitled to consent to corporate action in writing without a

action taken or proposed to be taken is delivered to the Corporation by delivery
to its registered office in this State, its principal place of business, or an
officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to a
corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested. If no record date has been fixed by the Board of
Directors and prior action by the Board of Directors is required by law, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting shall be at the close of business on the day on
which the Board of Directors adopts the resolutions taking such prior action.

                  (c) In order that the Corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of stock, or for the purpose of
any other lawful action, the Board of Directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty days
prior to such action. If no record date is fixed,

<PAGE>

the record date for determining stockholders for any such purpose shall be at
the close of business on the day on which the Board of Directors adopts the
resolution relating thereto.

                  SECTION 6. RECORD OWNERS. The Corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise required by
law.

                                   ARTICLE VI

                                     NOTICES

                  SECTION 1. NOTICES. Whenever written notice is required by
law, the Certificate of Incorporation or these By-Laws, to be given to any
director, member of a committee or stockholder, such notice may be given by
mail, addressed to such director, member of a committee or stockholder, at such
person's address as it appears on the records of the Corporation, with postage
thereon prepaid, and such notice shall be deemed to be given at the time when
the same shall be deposited in



                                       29
<PAGE>

the United States mail. Written notice may also be given personally or by
telegram, telex or cable.

                  SECTION 2. WAIVERS OF NOTICE. Whenever any notice is required
by law, the Certificate of Incorporation or these By-Laws, to be given to any
director, member of a committee or stockholder, a waiver thereof in writing,
signed, by the person or persons entitled to said notice, whether before or
after the time stated therein, shall be deemed equivalent thereto. Attendance of
a person at a meeting, present in person or represented by proxy, shall
constitute a waiver of notice of such meeting, except where the person attends
the meeting for the express purpose of objecting at the beginning of the meeting
to the transaction of any business because the meeting is not lawfully called or
convened.

                                   ARTICLE VII

                               GENERAL PROVISIONS

                  SECTION 1. DIVIDENDS. Dividends upon the capital stock of the
Corporation, subject to the requirements of the DGCL and the provisions of the
Certificate of Incorporation, if any, may be declared by the Board of Directors
at any regular or special meeting of the Board of Directors (or any action by
written consent in lieu thereof in accordance with Section 6 of Article III
hereof), and may be paid in cash, in property, or in shares of the Corporation's
capital stock. Before payment of 



                                       30
<PAGE>

any dividend, there may be set aside out of any funds of the Corporation
available for dividends such sum or sums as the Board of Directors from time to
time, in its absolute discretion, deems proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any

                     PRINCIPAL TERMS OF PRICELINE.COM OPTION PLAN


EXERCISE PRICE:  1.00 per share

TOTAL NUMBER OF SHARES OUTSTANDING:  Approximately 65,000,000 prior to exercise
of employee stock options.

VESTING:  Options vest over three years; the first allotment vest immediately;
an additional allotment vests on June 1, 1999 and June 1, 2000. A portion of
options for current employees are immediately vested as a result of the plan to
tie vesting of the first third of options to the successful launch of priceline.
For employees hired after July 1, 1998, the options will vest on the first three
anniversaries of the date of grant. The optionholder must remain employed by
priceline.com for options to vest provided, however, that if the optionholder
continues to be employed by a company controlled by Jay Walker, the optionholder
will be allowed pro rata vesting for the portion of the year employed by
priceline.com.

EXERCISE RIGHTS:  Options are exercisable for ten years from the date of grant
provided that the options are vested. Due to securities law requirements, it is
also a condition of exercise that priceline.com is a public company. Options
will become exercisable once priceline.com is a public company and any
applicable "holdback" period (typically 180 days from the date of the IPO)
imposed by the underwriters has expired.

EFFECT OF TERMINATION OF EMPLOYMENT:  Exercise rights are terminated immediately
if the employee is terminated for Cause. If employment terminates for reasons
other than Cause and the Company has not had an initial public offering, then
vested options shall remain exercisable until 90 days following the initial
public offering, provided, however, that the Company shall have the right to
repurchase such vested options for cash at a price equal to the difference
between the fair market value of the Company's shares and the exercise price at
any time prior to a public offering; and provided further, however, that the 90
day periods referred to above will be one year in the case of termination of
employment for death or disability. The Company repurchase rights described
above shall not apply so long as the optionholder is working for any company
controlled by Jay Walker.


                                           
<PAGE>

TAX STATUS:  The options will be non-qualified options (meaning the holder will
have taxable ordinary income upon exercise of the options and the Company will
have a tax deduction in the amount of the difference between the fair market
value of the stock at that time and the exercise price).

          be 18,000,000 Units (subject to adjustment as provided herein). The
          Committee may direct that any Unit certificate evidencing Units issued

          remain unissued upon the cancellation, surrender, exchange or

          Restricted Units forfeited. Notwithstanding the foregoing, upon the
          exercise of any Incentive Award granted in tandem with any other
          Incentive Awards, such related Awards shall be canceled to the extent
          of the number of Units as to which the Incentive Award is exercised
          and such number of Units shall no longer be available for Incentive
          Awards under the Plan.

4.   ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by the Committee. The Committee shall have
the authority in its sole discretion, subject to and not inconsistent with the
express provisions of the Plan, to administer the Plan and to exercise all the
powers and authorities either specifically granted to it under the Plan or
necessary or advisable in the administration of the Plan, including, without
limitation, the authority to grant Incentive Awards; to determine the persons to
whom and the time or times at which Incentive Awards shall be granted; to
determine the type and number of Incentive Awards to be granted, the number of
Units to which an Award may relate and the terms, conditions, restrictions and
performance criteria relating to any Incentive Award; to determine whether, to
what extent, and under what circumstances an Incentive 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
the Company or the financial statements of the Company (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 Plan and any Incentive Award; to prescribe, amend and rescind
rules and regulations relating to the Plan; to determine the terms and
provisions of Agreements; and to make all other determinations deemed necessary

Plan, (a) accelerate the date on which any Option or Stand-Alone UAR granted
under the Plan becomes exercisable, waive or amend the operation of Plan
provisions respecting exercise after termination of employment or otherwise
adjust any of the


                                          7
<PAGE>

terms of such Option or Stand-Alone UAR, and (b) accelerate the Vesting Date or
Issue Date, or waive any condition imposed hereunder, with respect to any
Restricted Units, Phantom Units or other Incentive Award or otherwise adjust any
of the terms applicable to any such Incentive Award.

     No member of the Committee shall be liable for any action, omission or
determination relating to the Plan, and the Company shall indemnify (to the
extent permitted under Delaware law and the Limited Liability Company Agreement
of the Company) and hold harmless each member of the Committee and each other
director or employee of the Company to whom any duty or power relating to the
administration or interpretation of the Plan has been delegated against any cost
or expense (including counsel fees) or liability (including any sum paid in
settlement of a claim with the approval of the Committee) arising out of any
action, omission or determination relating to the Plan, unless, in either case,
such action, omission or determination was taken or made by such member,
director or employee in bad faith and without reasonable belief that it was in
the best interests of the Company.

5.   ELIGIBILITY.

     The persons who shall be eligible to receive Incentive Awards pursuant to
the Plan shall be such employees, consultants and Managers of the Company as the
Committee shall select from time to time.

6.   AWARDS UNDER THE PLAN; AGREEMENT.

     The Committee may grant Options, Tandem UARs, Stand-Alone UARs, Restricted
Units, Phantom Units, Unit Bonuses and Other Awards in such amounts and with
such terms and conditions as the Committee shall determine, subject to the
provisions of the Plan.

     Each Incentive Award granted under the Plan (except an unconditional Unit
Bonus) shall be evidenced by an Agreement which shall contain such provisions as
the Committee may in its sole discretion deem necessary or desirable. By
accepting an Incentive Award, a Participant thereby agrees that the award shall
be subject to all of the terms and provisions of the Plan and the applicable
Agreement.

7.   OPTIONS.

     (a)  IDENTIFICATION OF OPTIONS.

          Each Option shall be clearly identified in the applicable Agreement as
          either an Incentive Stock Option or a Non-Qualified Unit Option.

     (b)  APPROVAL UPON CONVERSION TO CORPORATION.

          In order that options intended to be Incentive Stock Options qualify
          as such under the Code, within twelve (12) months following the
          conversion of the Company to a corporation, the stockholders of the
          Company shall approve the Plan in accordance with the then applicable
          provisions of the corporate charter and by-laws and the applicable law
          prescribing the method and degree of stockholder approval required for
          the issuance of corporate stock or options.

     (c)  EXERCISE PRICE.

          Each Agreement with respect to an Option shall set forth the amount
          (the "option exercise price") payable by the grantee to the Company
          upon exercise of the Option. The option exercise price per Unit shall
          be determined by the Committee; provided, however, that in the case of
          an Incentive Stock Option, the option exercise price shall in no event
          be less than the Fair Market Value of a Unit on the date the Option is
          granted.

     (d)  TERM AND EXERCISE OF OPTIONS.

          (1)  Incentive Stock Option must be granted within ten (10) years from
               the earlier of (i) the date the Plan is adopted or (ii) the date
               the Plan is approved by the stockholders of the Company pursuant
               to Section 7(b) above.

          (2)  Unless the applicable Agreement provides otherwise, an Option
               shall become cumulatively exercisable as to 33 1/3% percent of
               the Units covered thereby on each of the first, second and third
               anniversaries of the date of grant. The Committee shall determine
               the expiration date of each Option;


                                          9
<PAGE>

               provided, however, that no Option shall be exercisable more than
               10 years after the date of grant. Unless the applicable Agreement
               provides otherwise, no Option shall be exercisable prior to the
               first anniversary of the date of grant.

          (3)  An Option may be exercised for all or any portion of the Units as
               to which it is exercisable, provided that no Partial Exercise of
               an Option shall be for an aggregate exercise price of less than
               $100.00. The Partial Exercise of an Option shall not cause the
               expiration, termination or cancellation of the remaining portion
               thereof.

          (4)  An Option shall be exercised by delivering notice to the
               Company's principal office, to the attention of is Secretary.
               Such notice shall be accompanied by the applicable Agreement,
               shall specify the number of Units with respect to which the
               Option is being exercised and the effective date of the proposed
               exercise and shall be signed by the Participant or other person
               then having the right to exercise the Option. Payment for Units
               purchased upon the exercise of an Option shall be made on the
               effective date of such exercise by one or a combination of the
               following means: (i) in cash or by personal check, certified
               check, bank cashier's check or wire transfer; (ii) subject to the
               approval of the Committee, in Units 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 (iii) subject to the approval of the Committee, by such other
               provision as the Committee may from time to time authorize.

               entitled to receive such Units, and delivered to the Participant
               or such other person as soon as practicable following the
               effective date on which the Option is exercised.

          (6)  The Committee shall have the authority to specify, at the time of

<PAGE>

               Non-Qualified Unit Option (a "Reload Option") for a number of
               Units equal to the number of Units surrendered by the Participant
               upon exercise of all or a part of an Option in the manner
               described in Section 7(d)(4)(ii) above, subject to the
               availability of Units under the 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 Committee
               in its discretion, subject to the terms of the Plan.

          (7)  Each Option by its terms shall be nontransferable other than at
               death and must be exercisable during the Participant's lifetime
               only by the Participant.

     (e)  LIMITATIONS ON INCENTIVE STOCK OPTIONS.

          (1)  To the extent that the aggregate Fair Market Value of Units of
               the Company with respect to which Incentive Stock Options are
               exercisable for the first time by a Participant during any
               calendar year under the Plan and any other option plan of the
               Company (or any Subsidiary) shall exceed $ 100,000, such Options
               shall be treated as Non-Qualified Unit Options. Such Fair Market
               Value shall be determined as of the date on which each such
               Incentive Stock Option is granted.

          (2)  No Incentive Stock Option may be granted to an individual if, at
               the time of the proposed grant, such individual owns (or is
               attributed to own by virtue of the Code) Units possessing more
               than ten percent of the total combined voting power of all
               classes of stock of the Company or any Subsidiary unless (i) the
               exercise price of such Incentive Stock Option is at least 110
               percent of the Fair Market Value of a share of Company stock at
               the time such Incentive Stock Option is granted and (ii) such
               Incentive Stock Option is not exercisable after the expiration of
               five years from the date such Incentive Stock Option is granted.

          (1)  Unless the applicable Agreement provides otherwise, in the event
               that the employment, directorship or consultancy (together,
               hereinafter referred to as "employment") of a Participant with
               the Company shall terminate for any reason other than Cause,
               Disability or death, (i) Options granted to such Participant, to

               shall expire, and (ii) Options granted to such Participant, to

               Holdback Period, in the event of the Participant's death during
               such 90 day period. Notwithstanding the foregoing, no Option
               shall be exercisable after the expiration of its term.

          (2)  Unless the applicable Agreement provides otherwise, in the event
               that the employment of a Participant with the Company shall
               terminate on account of the Disability or death of the
               Participant, (i) Options granted to such Participant, to the
               extent that they were exercisable at the time of such
               termination, shall remain exercisable until the first anniversary
               of the later of (x) such termination or (y) the Initial Public
               Offering Date plus the Holdback Period, on which date they shall
               expire, and (ii) Options granted to such Participant, to the
               extent that they were not exercisable at the time of such
               termination, shall expire at the close of business on the date of
               such termination; provided, however, that no Option shall be
               exercisable after the expiration of its term.

          (3)  In the event of the termination of a Participant's employment for
               Cause, all outstanding Options granted to such Participant


                                          12

               shall expire at the commencement of business on the date of such
               termination.

8.   TANDEM UARs.

     The Committee may grant in connection with any Option granted hereunder,

          to the excess of (1) the Fair Market Value thereof on the exercise
          date over (2) the option exercise price of the related Option. Such
          payment shall be made as soon as practicable after the effective date
          of such exercise.

     (b)  TERM AND EXERCISE OF TANDEM UAR.

          (1)  A Tandem UAR shall be exercisable only if and to the extent that
               its related Option is exercisable.

          (2)  The exercise of a Tandem UAR with respect to a number of Units
               shall cause the immediate and automatic cancellation of its
               related Option with respect to an equal number of Units. The
               exercise of an Option, or the cancellation, termination or
               expiration of an Option (other than pursuant to this Section
               8(b)(2)), with respect to a number of Units shall cause the
               automatic and immediate cancellation of any related Tandem UARs
               to the extent of the number of Units subject to such Option which
               is so exercised, canceled, terminated or expired.

          (3)  A Tandem UAR may be exercised for all or any portion of the Units

               of less than S 1,000.

          (4)  No Tandem UAR shall be assignable or transferable otherwise than
               together with its related Option.

               shall specify the number of Units with respect to which the
               Tandem UAR is being exercised and the effective date of the
               proposed exercise and shall be signed by the Participant or other

          The exercise price per Unit of a Stand-Alone UAR shall be determined
          by the Committee at the time of grant, but shall in no event be less
          than the Fair Market Value of a Unit on the date of grant.

     (b)  BENEFIT UPON EXERCISE.

          The exercise of a Stand-Alone UAR with respect to any number of Units
          shall entitle the Participant to a payment, for each such Unit, equal
          to the excess of (1) the Fair Market Value thereof on the exercise
          date over (2) the exercise price of the StandAlone UAR.  Such payments
          shall be made as soon as practicable after such exercise, in cash
          and/or Units as determined by the Committee.

     (c)  TERM AND EXERCISE OF STAND-A LONE UARS.

          (1)  Unless the applicable Agreement provides otherwise, a Stand-Alone
               UAR shall become cumulatively exercisable as to 33 1/3 percent of
               the Units covered thereby on each of the first, second and third
               anniversaries of the date of grant. The Committee shall determine
               the expiration date of each


                                          14
<PAGE>

               standalone UAR.  Unless the applicable Agreement provides
               otherwise, no Standalone UAR shall be exercisable prior to the

               Exercise of a Stand-Alone UAR shall be for an aggregate exercise
               price of less than $1,000.

          (3)  A Stand-Alone UAR shall be exercised by delivering notice to the
               Company's principal office, to the attention of its Secretary.

          The provisions set forth in Section 7(f) with respect to the exercise

10.  RESTRICTED UNITS.

     (a)  ISSUE DATE AND VESTING DATE.

          establish an Issue Date or Issue Dates and a Vesting Date or Vesting
          Dates with respect to such Units. The Committee may divide such Units
          into classes and assign a different Issue Date and/or Vesting Date for
          each class. If the grantee is employed by the Company on an Issue Date
          (which may be the date of grant), the specified number of Restricted
          Units shall be issued in accordance with the provisions of Section
          10(e). Provided that all conditions to the vesting of Restricted Units
          imposed pursuant to Section 10(b) are satisfied, and except as
          provided in Section 10(g), upon the occurrence of the Vesting Date
          with respect to Restricted Units, such Units shall vest and the
          restrictions of Section 10(c) shall lapse.


                                          15
<PAGE>

     (b)  CONDITIONS TO VESTING.

          At the time of the grant of Restricted Units, the Committee may impose
          such restrictions or conditions to the vesting of such Units as it, in
          its absolute discretion, deems appropriate.

     (c)  RESTRICTIONS ON TRANSFER PRIOR TO VESTING.

          Prior to the vesting of any Restricted Units, no transfer of a
          Participant's rights with respect to such Unit, whether voluntary or
          involuntary, by operation of law or otherwise, shall be permitted.
          Immediately upon any attempt to transfer such rights, such Units, and
          all of the rights related thereto, shall be forfeited by the
          Participant.

     (d)  DIVIDENDS ON RESTRICTED UNIT.

          The Committee in its discretion may require that any dividends or
          distributions paid on Restricted Units be held in escrow until all
          restrictions on such Units have lapsed.

     (e)  ISSUANCE OF CERTIFICATES.

          (1)  Reasonably promptly after the Issue Date with respect to
               Restricted Units, the Company shall cause to be issued a
               certificate, registered in the name of the Participant to whom
               such Units were granted, evidencing such Units; provided that the
               Company shall not cause such a certificate to be issued unless it
               has received a power of attorney duly endorsed in blank with
               respect to such Units. Each such certificate shall bear the
               following legend:

                    THE TRANSFERABILITY OF THIS CERTIFICATE AND THE UNITS
                    REPRESENTED HEREBY ARE SUBJECT TO THE RESTRICTIONS, TERMS
                    AND CONDITIONS (INCLUDING FORFEITURE PROVISIONS AND
                    RESTRICTIONS AGAINST TRANSFER) CONTAINED IN THE
                    PRICELINE.COM LLC 1997 OMNIBUS PLAN AND AN AGREEMENT ENTERED
                    INTO BETWEEN THE REGISTERED OWNER OF SUCH UNITS AND

                    THE SECRETARY OF THE COMPANY.

               Such legend shall not be removed until such Units vest pursuant
               to the terms hereof.

          (2)  Each certificate issued pursuant to this Section 10(e), together
               with the powers relating to the Restricted Units evidenced by
               such certificate, shall be held by the Company unless the
               Committee determines otherwise.

     (f)  CONSEQUENCES OF VESTING.

          Upon the vesting of any Restricted Units pursuant to the terms hereof,
          the restrictions of Section 10(c) shall lapse with respect to such
          Units. Reasonably promptly after any Restricted Units vest, the
          Company shall cause to be delivered to the Participant to whom such
          Units were granted a certificate evidencing such Units, free of the
          legend set forth in Section 10(e).

     (g)  EFFECT OF TERMINATION OF EMPLOYMENT.

          (1)  Subject to such other provision as the Committee may set forth in
               the applicable Agreement, and to the Committee's amendment
               authority pursuant to Section 4, upon the termination of a
               Participant's employment for any reason other than Cause, any and
               all Units to which restrictions on transferability apply shall be
               immediately forfeited by the Participant and transferred to, and
               reacquired by, the Company; provided that if the Committee, in
               its sole discretion, shall within thirty (30) days after such
               termination of employment notify the Participant in writing of
               its decision not to terminate the Participant's rights in such
               Units, then the Participant shall continue to be the owner of
               such Units subject to such continuing restrictions as the
               Committee may prescribe in such notice. In the event of a
               forfeiture of Units pursuant to this section, the Company shall
               repay to the Participant (or the Participants estate) any amount
               paid by the Participant for such Units. In the event that the
               Company requires a return of Units, it shall also have the


                                          17
<PAGE>

               right to require the return of all dividends or distributions
               paid on such Units, whether by termination of any escrow
               arrangement under which such dividends or distributions are held
               or otherwise.

          (2)  In the event of the termination of a Participant's employment for
               Cause, all Restricted Units granted to such Participant which
               have not vested as of the date of such termination shall
               immediately be returned to the Company, together with any
               dividends or distributions paid on such Units, in return for
               which the Company shall repay to the Participant any amount paid
               by the Participant for such Units.

     (h)  SPECIAL PROVISIONS REGARDING AWARDS.

          Notwithstanding anything to the contrary contained herein, Restricted
          Units granted pursuant to this Section 10 to Executive Officers may be
          based on the attainment by the Company (or a Subsidiary or division of
          the Company if applicable) of performance goals pre-established by the
          Committee, based on one or more of the following criteria: (1) the
          attainment of a specified percentage return on total owner equity; (2)
          the attainment of a specified percentage increase in earnings per
          Unit, (3) the attainment of a specified percentage increase in net
          income (before or after taxes); (4) the attainment of a specified
          percentage increase in earnings before interest, taxes, depreciation
          and amortization; (5) a specified percentage increase in earnings
          before interest and income taxes, as adjusted for office overhead
          expense allocation; (6) a specified percentage increase in revenues;
          (7) a specified minimum return on assets; and (8) such other criteria
          as the unitholders of the Company may approve; in each case, as
          determined in accordance with generally accepted accounting
          principles. Such Restricted Units shall be released from restrictions
          only after the attainment of such performance measures have been
          certified by the Committee.

          Subject to such other provision as the Committee may set forth in the
          applicable Agreement, and to the Committee's amendment authority
          pursuant to Section 4, Phantom Units that have not vested, together
          with any dividends or distributions credited on such Units, shall be
          forfeited upon the Participant's termination of employment for any
          reason.

     (e)  SPECIAL PROVISIONS REGARDING AWARDS.

          Notwithstanding anything to the contrary contained herein, the vesting
          of Phantom Units granted pursuant to this Section 11 to Executive
          Officers may be based on the attainment by the Company (or a
          Subsidiary or division of the Company if applicable) of one or more of
          the performance criteria set forth in Section 10(h) hereof, in each
          case, as determined in accordance with generally accepted accounting
          principles. No payment in respect of any such Phantom Units award will
          be paid to an Executive Officer until the attainment of the respective
          performance measures have been certified by the Committee.

12.  STOCK BONUSES.

     In the event that the Committee grants a Unit Bonus, a certificate for the
Units comprising such Unit Bonus shall be issued in the name of the Participant
to whom such grant was made and delivered to such Participant as soon as
practicable after the date on which such Unit Bonus is payable. Executive
Officers shall be eligible to receive Unit Bonus grants hereunder only after a
determination of eligibility is made by the Committee, in its sole discretion.

13.  OTHER AWARDS.

     Other forms of Incentive Awards ("Other Awards") valued in whole or in part
by reference to, or otherwise based on, Units may be granted either alone or in
addition to other Incentive Awards under the Plan. Subject to the provisions of
the Plan, the Committee shall have sole and complete authority to determine the
persons to whom and the time or times at which such Other Awards shall be
granted, the number of Units to be granted pursuant to such Other Awards and all
other conditions of such Other Awards.

14.  RIGHTS AS A UNITHOLDER.

     No person shall have any rights as a member or unitholder with respect to
any Units covered by or relating to any Incentive Award until the date of
issuance of a certificate with respect to such Units. Except as otherwise
expressly provided in Section 3(b), no adjustment to any Incentive Award shall
be made for dividends or other rights prior to the date such certificate is
issued.


                                          20

15.  NO SPECIAL EMPLOYMENT RIGHTS; NO RIGHT TO INCENTIVE AWARD.

     Nothing contained in the Plan or any Agreement shall confer upon any
Participant any right with respect to the continuation of employment by the
Company or interfere in any way with the right of the Company, subject to the
terms of any separate employment agreement to the contrary, at any time to
terminate such employment or to increase or decrease the compensation of the
Participant.

     No person shall have any claim or right to receive an Incentive Award
hereunder. The Committee's granting of an Incentive Award to a participant at
any time shall neither require the Committee to grant any other Incentive Award
to such Participant or other person at any time or preclude the Committee from
making subsequent grants to such Participant or any other person.

16.  SECURITIES MATTERS.

     (a)  The Company shall be under no obligation to effect the registration
          pursuant to the Securities Act of any interests in the Plan or any
          Units to be issued hereunder or to effect similar compliance under any
          state laws. Notwithstanding anything herein to the contrary, the
          Company shall not be obligated to cause to be issued or delivered any
          certificates evidencing Units pursuant to the Plan unless and until
          the Company is advised by its counsel that the issuance and delivery
          of such certificates is in compliance with all applicable laws,
          regulations of governmental authority and the requirements of any
          securities exchange on which Units are traded. The Committee may
          require, as a condition of the issuance and delivery of certificates
          evidencing Units pursuant to the terms hereof, that the recipient of
          such Units make such agreements and representations, and that such
          certificates bear such legends, as the Committee, in its sole
          discretion, deems necessary or desirable.

     (b)  The transfer of any Units hereunder shall be effective only at such
          time as counsel to the Company shall have determined that the issuance
          and delivery of such Units is in compliance with all applicable laws,
          regulations of governmental authority, the requirements of any
          securities, exchange on which Units are traded and the terms and
          conditions of the Company's Limited Liability Company Agreement. The
          Committee may, in its sole discretion, defer the effectiveness of


                                          21
<PAGE>

          any transfer of Units hereunder in order to allow the issuance of such
          Units to be made pursuant to registration or an exemption from
          registration or other methods for compliance available under federal
          or state securities laws. The Committee shall inform the Participant
          in writing of its decision to defer the effectiveness of a transfer.
          During the period of such deferral in connection with the exercise of
          an Option, the Participant may, by written notice, withdraw such
          exercise and obtain the refund of any amount paid with respect
          thereto.

17.  WITHHOLDING TAXES.

     Whenever cash is to be paid pursuant to an Incentive Award, the Company
shall have the right to deduct therefrom an amount sufficient to satisfy any
federal, state and local withholding tax requirements related thereto.

     Whenever Units are to be delivered pursuant to an Incentive Award, the
Company shall have the right to require the Participant to remit to the Company
in cash an amount sufficient to satisfy any federal, state and local withholding
tax requirements related thereto. With the approval of the Committee, a
Participant may satisfy the foregoing requirement by electing to have the
Company withhold from delivery Units having a value equal to the amount of tax
to be withheld. Such Units shall be valued at their Fad Market Value on the date
of which the amount of tax to be withheld is determined (the "Tax Date").
Fractional Unit amounts shall be settled in cash. Such a withholding election
may be made with respect to all or any portion of the Units to be delivered
pursuant to an Incentive Award.

18.  NOTIFICATION OF ELECTION UNDER SECTION 83(b) OF THE CODE.

     If any Participant shall, in connection with the acquisition of Units under
the Plan, make the election permitted under Section 83(b) of the Code (i.e.) an
election to include in gross income in the year of transfer the amounts
specified in Section 83(b)), such Participant shall notify the Company of such
election within 10 days of filing notice of the election with the Internal
Revenue Service, in addition to any filing and a notification required pursuant
to regulation issued under the authority of Section 83(b) of the Code.


                                          22
<PAGE>

19.  NOTIFICATION UPON DISQUALIFYING DISPOSITION UNDER SECTION 421(b) OF THE
     CODE.

     Each Participant shall notify the Company of any disposition of Units
issued pursuant to the exercise of an Incentive Stock Option under the
circumstances described in Section 421(b) of the Code (relating to certain
disqualifying dispositions), within 10 days of such disposition.

20.  AMENDMENT OR TERMINATION OF THE PLAN.

     The Board of Managers may, at any time, suspend or terminate the Plan or
revise or amend it in any respect whatsoever; provided, however, that unitholder
approval shall be required if and to the extent required by Rule 16b-3 or by any
comparable or successor exemption under which the Board of Managers believes it
is appropriate for the Plan to qualify, or if and to the extent the Board of
Managers determines that such approval is appropriate for purposes of satisfying
Section 162(m) or 422 of the Code. Incentive Awards may be granted under the
Plan prior to the receipt of such approval but each such grant shall be subject
in its entirety to such approval and no award may be exercised, vested or
other-wise satisfied prior to the receipt of such approval. Nothing herein shall
restrict the Committee's ability to exercise its discretionary authority
pursuant to Section 4, which discretion may be exercised without amendment to
the Plan. No action hereunder may, without the consent of a Participant, reduce
the Participant's rights under any outstanding Incentive Award.

21.  TRANSFERS UPON DEATH; NONASSIGNABILITY.

     Upon the death of a Participant, outstanding Incentive Awards granted to
such Participant may be exercised only by the executor or administrator of the
Participant's estate or by a person who shall have acquired the right to such
exercise by will or by the laws of descent and distribution. No transfer of an
Incentive Award by will or the laws of descent and distribution shall be
effective to bind the Company unless the Committee shall have been furnished
with (a) written notice thereof and with a copy of the will and/or such evidence
as the Committee may deem necessary to establish the validity of the transfer
and (b) an agreement by the transferee to comply with all the terms and
conditions of the Incentive Award that are or would have been applicable to the
Participant and to be bound by the acknowledgments made by the Participant in
connection with the grant of the Incentive Award.


                                          23
<PAGE>

     During a Participant's lifetime, the Committee may permit the transfer,
assignment or other encumbrance of an outstanding Option unless (y) such Option
is an Incentive Stock Option and the Committee and the Participant intend that
it shall retain such status, or (z) such Option is meant to qualify for the
exemptions available under Rule 16b-3, nontransferability is necessary under
Rule 16b-3 in order for the award to so qualify and the Committee and the
Participant intend that it shall continue to so qualify: Subject to any
conditions as the Committee may prescribe, a Participant may, upon providing
written notice to the Secretary of the Company, elect to transfer any or all
Options granted to such Participant pursuant to the Plan to members of his or
her immediate family, including, but not limited to, children, grandchildren and
spouse or to trusts for the benefit of such immediate family members or to
partnerships in which such family members are the only partners; provided,
however, that no such transfer by any Participant may be made in exchange for
consideration.

22.  EXPENSES AND RECEIPTS.

     The expenses of the Plan shall be paid by the Company. Any proceeds
received by the Company in connection with any Incentive Award will be used for
general corporate purposes.

23.  FAILURE TO COMPLY.

     In addition to the remedies of the Company elsewhere provided for herein,
failure by a Participant (or beneficiary) to comply with any of the terms and
conditions of the Plan or the applicable Agreement, unless such failure is
remedied by such Participant (or beneficiary) within ten days after notice of
such failure by the Committee, shall be grounds for the cancellation and
forfeiture of such Incentive Award, in whole or in part, as the Committee, in
its absolute discretion, may determine.

24.  EFFECTIVE DATE AND TERM OF PLAN.

     The Plan became effective on the Effective Date, but the Plan (and any
grants of Incentive Awards made prior to approval of the Plan) shall be subject
to any requisite approval of the unitholders of the Company. Unless earlier
terminated by the Board of Managers, the right to grant Incentive Awards under
the Plan will terminate on the tenth anniversary of the Effective Date.
Incentive Awards outstand-


                                          24
<PAGE>

ing at Plan termination will remain in effect according to their terms and the
provisions of the Plan.

25.  APPLICABLE LAW.

     Except to the extent preempted by any applicable federal law, the Plan will
be construed and administered in accordance with the laws of the State of
Delaware, without reference to its principles of conflicts of law.

26.  PARTICIPANT RIGHTS.

     No Participant shall have any claim to be granted any award under the Plan,
and there is no obligation for uniformity of treatment for Participants. Except
as provided specifically herein, a Participant or a transferee of an Incentive
Award shall have no rights as a unitholder with respect to any Units covered by
any award until the date of the issuance of a certificate to him or her for such
Units.

27.  UNFUNDED STATUS OF AWARDS.

     The Plan is intended to constitute an "unfunded" plan for incentive and
deferred compensation. With respect to any payments not yet made to a
Participant pursuant to an Incentive Award, nothing contained in the Plan or any
Agreement shall give any such Participant any rights that are greater than those
of a general creditor of the Company.

28.  BENEFICIARY.

     If Participant may file with the Committee a written designation of a
beneficiary on such form as may be prescribed by the Committee and may, from
time to time, amend or revoke such designation. If no designated beneficiary
survives the Participant, the executor or administrator of the Participant's
estate shall be deemed to be the grantee's beneficiary.

29.  INTERPRETATION.

     The Plan is designed and intended to comply with Rule 16b-3 and, to the
extent applicable, with Section 162(m) of the Code, and all provisions hereof
shall be construed in a manner to so comply. Further, in the event there is a
conflict between the terms of the Plan or any Optionholder Agreement and the
terms of the Company's


                                          25
<PAGE>

Limited Liability Agreement or other organizational documents, the provisions of
such Limited Liability Company Agreement or other organizational document shall
control.

30.  SEVERABILITY.

     If any provision of the Plan is held to be invalid or unenforceable, the
other provisions of the Plan shall not be affected but shall be applied as if
the invalid or unenforceable provision had not been included in the Plan.

          In consideration of the Investment and the rights, conveyances,

Article II of this Agreement and Walker Digital's Initial Investment,
priceline.com hereby agrees as follows:

               (a)  Effective as of January 1, 1998, priceline.com hereby agrees

similar items), developed and owned by priceline.com from and after the

                                      ARTICLE IV

                                  INTERCOMPANY LEASE

          4.1  LEASE OF SPACE.  Commencing on and as of the Effective Date and
continuing on a month-to-month basis thereafter, Walker Digital shall sublease
to the PriceLine Parties all or a portion of the real estate leased by Walker
Digital at Five High Ridge Park, Stamford, Connecticut 06905 (the "WALKER LEASED
SPACE").  The portions of

<PAGE>
                                                                               6


the Walker Leased Space subject to the Intercompany Lease may, depending on the
occupancy requirements of the PriceLine Parties, fluctuate from time to time
during the term of the Intercompany Lease.  On not less than a quarterly basis
commencing with the calendar quarter beginning July 1, 1998, Walker Digital and
priceline.com shall determine in good faith the portion of the Walker Leased
Space then occupied by the PriceLine Parties (the "PRICELINE OCCUPIED SPACE")
for purposes of the payment obligations of the PriceLine Parties set forth in
section 4.2 below.   

          4.2  LEASE AND OTHER PAYMENTS.  The monthly rent payable by the
PriceLine Parties under the Intercompany Lease shall be equal to Walker
Digital's monthly base rental payment for leasing the PriceLine Occupied Space
then occupied by the PriceLine Parties (as determined by Walker Digital and
priceline.com as required by Section 4.1 above).  In addition to the foregoing,
the PriceLine Parties shall pay to Walker Digital, on a monthly basis after

                                 EMPLOYMENT AGREEMENT


          EMPLOYMENT AGREEMENT, dated as of January 1, 1998 by and among Mr. Jay
Walker (the "Stockholder"), Walker Digital Corporation, a Connecticut
corporation ("Walker Digital"), priceline.com LLC, a Delaware limited liability
company ("PriceLine" and, together with Walker Digital, the "Companies"), and
Mr. Jesse Fink, a resident of the State of Connecticut (the "Employee").

          WHEREAS, the Stockholder (or trusts established for the benefit of
members of the Stockholder's family) currently owns substantially all of the
issued and outstanding common stock, without par value, of Walker Digital
("Walker Digital Stock");

          WHEREAS, the Stockholder (or trusts established for the benefit of
members of the Stockholder's family) and Walker Digital currently own
substantially all of the common equity units of PriceLine ("PriceLine Units");
and

     WHEREAS, the Stockholder and the Companies desire that the Employee
continue to serve as the Chief Operating Officer of PriceLine and the Employee
desires to continue to so serve under the terms and conditions of this
Agreement.

          NOW, THEREFORE, intending to be legally bound hereby, the parties
agree as follows:

          1.   EMPLOYMENT.

          (a)  The Companies agree to continue to employee the Employee, and the
Employee hereby agrees to continue to serve the Companies, upon the terms and
subject to the conditions set forth herein. The Companies hereby agree to
continue to engage the Employee, and the Employee hereby agrees to continue to
serve, as a the Chief Operating Officer of each of the Companies upon the terms
and subject to the conditions set forth herein.

                                           
<PAGE>

          (b)  During the Term (as defined herein), the Employee shall  serve as
the Chief Operating Officer of each of the Companies and shall have such
responsibilities, duties and authority consistent with the position of Chief
Operating Officer as may from time to time be determined by the respective board
of directors of each of the Companies.

          (c)  During the Term, the Employee shall diligently and faithfully
serve the Companies and devote substantially all of his working time and efforts
to the business and affairs of the Companies.

          (d)     Upon the mutual agreement of the Employee and the Stockholder,
the Employee may be employed pursuant to this Agreement by an entity (the "New
Employer") other than the Companies that is controlled by the Stockholder, in
which event (i) the Employee shall be deemed to be employed by the New Employer
pursuant to the terms of this Agreement and the Term shall continue as if the
Employee continued to be employed by the Companies, (ii) the Employee shall be
entitled to the Options vested at the time of such transfer of employment and
(iii) (A) the Employee shall have the right to receive options to purchase
equity interests in the New Employer in lieu of the Options that are not vested
at the time of such transfer of employment and (B) the Employee and the
Stockholder shall negotiate in good faith to ensure that such options have an
equivalent profit opportunity over the term of this Agreement as the unvested
Options at the time of such transfer.  For example, if the reasonably anticipate
value of the unvested Options at the time of the Employee's transfer of
employment equals $2 million, then the Employee would receive options to
purchase equity interests in the New Employer valued at $2 million that would be
subject to the same terms and conditions as the unvested Option.   

          2.   TERM.  Subject to Section 5 hereof, the term of the employment by
the Companies of the Employee pursuant to this Agreement (the "Term") is for an
initial period commencing on January 1, 1998 and terminating on January 1, 2001.

          3.   COMPENSATION.

          (a)  BASE SALARY.  In partial consideration of the Employee's services
to be rendered pursuant hereto and the Employee's agreement to the covenants and
restrictions set forth in Section 8 hereof, the Companies shall pay to the
Employee, effective as of January 1, 1998, an annual base salary of $225,000, 


                                          2
<PAGE>

subject to annual adjustment (the "Base Salary"), such salary to be payable to
the employee in semi-monthly installments in accordance with the Companies'
customary payroll practices.  PriceLine and Walker Digital will allocate such
payments between them in their discretion.

          (b)  CASH BONUS.    The Employee shall be eligible to participate in
any cash bonus program introduced by PriceLine at a level commensurate with the
Employee's position and responsibility.

          (c)  ISSUANCE OF PRICELINE UNITS.  In partial consideration for the
services previously rendered by the Employee, the services to be rendered
pursuant hereto and the Employee's agreement to the covenants and restrictions
set forth in Section 8 hereof, PriceLine shall issue and deliver to the Employee
on the date of this Agreement a certificate or certificates representing
2,700,000 PriceLine Units (representing approximately 36% of the founders'
equity of PriceLine and approximately 3.9% of PriceLine's estimated
capitalization), free and clear of any lien, encumbrance, security interest,
mortgage, pledge, charge, claim, option, right of first refusal or call, or
restriction of any kind, other than the restrictions provided for herein.  Upon
such delivery of PriceLine Units, the Employee shall agree in writing to be
bound by the terms and conditions of the Limited Liability Company Agreement
dated as of July 18, 1997 by and among PriceLine and its members (as the same
may be amended through the time of exercise or any successor agreement, the
"PriceLine LLC Agreement") and any other agreement pertaining to the rights of
equity holders of PriceLine, and will, if requested by PriceLine or the
Stockholder, execute a separate statement to such effect.

          (d)  PRICELINE OPTION.

               (i)  In partial consideration for the services previously
rendered by the Employee, the services to be rendered pursuant hereto and the
Employee's agreement to the covenants and restrictions set forth in Section 8
hereof, PriceLine hereby grants to the Employee, effective as of the date
hereof, an option (the "PriceLine Option") to purchase, on the terms set forth
in this Section 3(d), up to 2,200,000 PriceLine Units, which represent
approximately 3.2% of PriceLine's estimated capitalization.

               (ii) The PriceLine Option is not intended to qualify as an
incentive stock option within the meaning of Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code").


                                          3
<PAGE>

               (iii)  The PriceLine Option is exercisable at an aggregate
exercise price of $2,200,000, or a per security exercise price of $1.00 per
PriceLine Unit.

               (iv)   Subject to Section 5 hereof, the PriceLine Option shall
become exercisable as to (A) 1,200,000 of the PriceLine Units underlying the
PriceLine Option on the earlier of (x) the day on which the 5,000th airline
ticket is sold through PriceLine's priceline.com website and (y) December 31,
1998 (the "Launch Vesting Date"); (B) 500,000 of the PriceLine Units underlying
the PriceLine Option on the first anniversary of the Launch Vesting Date; and
(C) 500,000 of the PriceLine Units underlying the PriceLine Option on the second
anniversary of the Launch Vesting Date.

               (v)    Except as otherwise specifically provided for in this
Agreement, the PriceLine Option shall be governed by the terms of the Omnibus
PriceLine Option Plan and related Option Agreement.

          (e)  WD/CASH OPTION.

               (i)    In partial consideration for the services previously
rendered by the Employee, the services to be rendered pursuant hereto and the
Employee's agreement to the covenants and restrictions set forth in Section 8
hereof, Walker Digital hereby grants to the Employee, effective as of the date
hereof and upon the terms set forth in this Section 3(e), an option (the
"WD/Cash Option," and together with the PriceLine Option, the "Options" ) to (A)
purchase up to 500 shares of Walker Digital Stock, which represent approximately
 .5% of Walker Digital's estimated capitalization or (B) elect to receive a cash
payment (the "Cash Payment") from the Stockholder in an amount equal of the
product of (1) the difference between (x) the per share fair market value (as
determined pursuant to Section 3(e)(vi) hereof) of the common stock of NewSub
Services, Inc., a Connecticut corporation ("NewSub"), on the date of exercise of
the WS/Cash Option minus (y) $30,709.74 (the per share fair market value of the
common stock of NewSub on the date hereof) multiplied by (2) 32.563 (the
"Reference Factor").

               (ii)   The WD/Cash Option is not intended to qualify as an
incentive stock option within the meaning of Section 422 of the Code.


                                          4
<PAGE>

               (iii)  The WD/Cash Option is exercisable in the aggregate for
(A) 500 shares of Walker Digital Stock at an aggregate exercise price of
$1,000,000, or a per security exercise price of $2,000 per share of Walker
Digital Stock (the "WD/Cash Exercise Price") or (B) the Cash Payment. 

               (iv)   The per security exercise price for Walker Digital Stock
was determined on the basis of a $200 million valuation of Walker Digital, after
giving effect to presently anticipated equity transactions. The Reference Factor
of 32.563 was determined on the basis of a $270 million valuation of NewSub and
8,792 issued and outstanding shares of common stock of NewSub as of March 9,
1998. 
 
               (v)    The WD/Cash Option shall become exercisable upon the
issuance of the WD/Cash Option.  The WD/Cash Option may be exercised for Walker
Digital Stock or the Cash Payment by written notice delivered in person or by
mail to Walker Digital and the Stockholder specifying either the number of
shares of Walker Digital Stock that the WD/Cash Option is being exercised for or
that the WD/Cash Option is being exercised for the Cash Payment.  If the WD/Cash
Option is exercised for Walker Digital Stock, the WD/Cash Exercise Price shall
be paid in full and in cash at the time of exercise to Walker Digital.  Unless
sooner exercised or terminated pursuant to the terms of this Agreement, the
WD/Cash Option shall be cancelled and be of no further force and effect after
January 1, 2001 (the "Expiration Date").

               (vi)   The per share fair market value of the common stock of
NewSub on the date of exercise of the WD/Cash Option shall be determined in good
faith by the Stockholder, PROVIDED, HOWEVER, if the Employee challenges such
valuation within thirty (30) days of being notified of such valuation, then the
valuation shall be determined in the following manner:  

                      (A) First, the Stockholder and the Employee shall each
select a financial advisor who shall work together to determine the per share
fair market value of the common stock of NewSub on the date of exercise of the
WD/Cash Option; and 

                      (B) Second, if the financial advisors of the Stockholder
and the Employee are not able to mutually agree on the per share fair market
value of the common stock of NewSub on the date of exercise of the


                                          5
<PAGE>

WD/Cash Option, then the financial advisors shall jointly select a third
financial advisor to determine such value.

               (vii)  In determining the per share fair market value of the
common stock of NewSub on the date of exercise of the WD/Cash Option pursuant to
Section 3(e)(vi) , the Stockholder and the Employee shall each be responsible
for the fees, costs and expenses of their own financial advisor and shall
equally divide the fees, costs and expenses of the third financial advisor. 

          (f)  ISSUANCE OF WALKER DIGITAL STOCK.   The Employee will be issued
10% of the Walker Digital Stock as founder's equity effectively granted "as of"
June 30, 1996.  This investment was diluted by capital contributions in the
amount of $5,977,843 that were made by the Stockholder from June 30, 1996
through December 31, 1997 based on a $20 million pre-investment valuation,
thereby diluting the Employee's equity stake to 7.7% by virtue of the
Stockholder's investment during such period.  Such issuance will be in the form
of a profits interest and will be made as soon as practicable following the
recapitalization of Walker Digital to an limited liability company.  The
tag-along and conversion provisions set forth in Section 3(g) hereof shall also
apply to the units received in such grant.  The Employee will have the right to
maintain his base 10% stake in Walker Digital by giving the Stockholder a
personal recourse note accumulating interest at the rate of 12% compounded
annually in a principal amount equal to 10% of the Stockholder's investment
during this period (i.e., $597,784).  The Stockholder's investment in Walker
Digital beginning January 1, 1998 will be based on a $100 million valuation,
subject to adjustment up or down based on changes in fair market value and
subject to fiduciary obligations to other shareholders.  The Employee will have
the right to preserve his ownership percentage in Walker Digital by investing
cash in Walker Digital at the same valuation as any new investments.  The
Employee will be diluted ratably with the Stockholder for the $5 million of
Walker Investment Unit subscriptions based on a $200 million valuation of Walker
Digital, thereby reducing Employee's investment ownership to 7.7%.  The Employee
will have the right to co-invest with the Stockholder on a pari passu basis in
any venture that licenses or otherwise receives Walker Digital intellectual
property.  In addition, it is currently anticipated that the Employee will
receive 30% of a management participation pool of 20% (i.e., 6% of the total) of
the 1996 Walker Digital patents and 20% of a management participation pool of
20% (i.e., 4% of the total) of the 1997 Walker Digital patents.  Walker Digital
will hold approximately 7.3% of the fully diluted equity of PriceLine.  In the
event that Walker Digital does not create any such management participation
pools or effect


                                          6
<PAGE>

the aforementioned recapitalization, the Employee and the Stockholder will
negotiate in good faith for a comparable management participation arrangement or
comparable founders' stock arrangement, as the case may be..

          (g)  ADJUSTMENT. 

               (i)  In the event that, following March 9, 1998, Walker Digital
or PriceLine effects an extraordinary dividend or other extraordinary
distribution, recapitalization, stock split, reverse stock split,
reorganization, merger, consolidation, spin-off, combination, repurchase or
share exchange, or other similar corporate transaction or event that affects the
Walker Digital Stock, PriceLine Units, as the case may be, such that an
adjustment is appropriate to prevent dilution or enlargement of the rights of
the Employee with respect to the Options, then Walker Digital or PriceLine, as
the case may be, shall make such equitable changes or adjustments as Walker
Digital, with respect to the Walker Digital Stock, and PriceLine with respect to
the PriceLine Units, deems necessary or appropriate to any or all of (A) the
number and kind of equity securities for which the Options are exercisable and
(B) exercise price of the Options.

               (ii)  In the event that, following March 9, 1998, NewSub effects
an extraordinary dividend or other extraordinary distribution, recapitalization,
stock split, reverse stock split, reorganization, merger, consolidation,
spin-off, combination, repurchase or share exchange, or other similar corporate
transaction or event that affects the common stock of NewSub, such that an
adjustment is appropriate to prevent dilution or enlargement of the rights of
the Employee with respect to the WD/Cash Option, then the Stockholder shall make
such equitable changes or adjustments to the WD/Cash Option as the Stockholder
deems necessary or appropriate to the maximum Reference Factor and Section
3(e)(3).  For example, in the event that NewSub declares a two-for-one stock
split the maximum Reference Factor would be increased to 65.126 and Section
3(e)(3) would be adjusted accordingly.  

               (iii)  The parties hereto acknowledge and understand that
ordinary dividends and/or additional issuances of equity securities by Walker
Digital, PriceLine or NewSub for cash or property shall not result in an
adjustment under this Section 3(g), unless such issuances are to the Stockholder
or any member of the Stockholder's immediate family or any entity controlled by
the Stockholder or pursuant to a transaction that is not an "arm's length"
purchase of


                                          7
<PAGE>

such securities, in either case, at a valuation less than the valuations set
forth in Sections 3(d) and 3(e) hereof.

          (h)  BENEFITS.  During the Term, Walker Digital or PriceLine shall
provide the Employee with health, welfare and insurance benefits to the extent
and on the same terms as it provides such benefits to its executive officers. 
The Employee also shall be entitled to participate in and receive any fringe
benefits or perquisites which may become available to the Companies' executive
officers.

          (i)  TAG-ALONG RIGHTS; CONVERSION.  

               (i)  Except as set forth below, if the Stockholder proposes to
transfer, sell or otherwise dispose of PriceLine Units or shares of Walker
Digital Stock (other than to an affiliate, as defined in Rule 12b-2 promulgated
under the Securities Exchange Act of 1934, as amended, of the Stockholder), the
Stockholder shall provide the Employee with not less than ten business days'
prior written notice of such proposed sale, which notice shall include all of
the terms and conditions of such proposed sale and identify the proposed
purchaser(s) ("Tag-Along Purchaser(s)") of such securities (the "Sale Notice"). 
The Employee shall have the option, exercisable by written notice given to the
Stockholder within ten business days after receipt of the Sale Notice, to
require the Stockholder to arrange for such Tag-Along Purchaser(s) to purchase
from the Employee, together with the Stockholder's securities, that number of
PriceLine Units or shares of Walker Digital Stock, as the case may be ("Employee
Put Shares"), equal to the product, rounded down to the nearest whole number, of
(a) a fraction, the numerator of which is the number of PriceLine Units or
shares of Walker Digital Stock, as the case may be, proposed to be sold by the
Stockholder and the denominator of which is the number of PriceLine Units or
shares of Walker Digital Stock, as the case may be, then owned by the
Stockholder, multiplied by (b) the number of PriceLine Units or shares of Walker
Digital Stock, as the case may be, then owned by the Employee, or any lesser
number of shares of such securities as the Employee shall desire.  If the
Employee shall so elect, the Stockholder shall either (y) arrange for such
Tag-Along Purchaser(s) to purchase the Employee Put Shares at the same time as
and upon the same terms (including price per PriceLine Unit or share of Walker
Digital Stock) and conditions (including all direct or indirect consideration or
compensation) at which the Stockholder sells his PriceLine Units or shares of
Walker Digital Stock, as the case may be (it being understood that in the event
the Employee Put Shares require exercise, con-


                                          8
<PAGE>

version or exchange to effect such sale, such exercise, conversion or exchange
may be made simultaneously with the closing of such sale), and provided that if
such Tag-Along Purchaser(s) elect to purchase only such aggregate number of
securities as originally agreed with the Stockholder, then the number of
securities to be sold by the Stockholder and the Employee shall be reduced pro
rata to such aggregate number or (z) not effect the proposed sale to such Tag
Along Purchaser(s).

                      (ii)  Upon the conversion of PriceLine from a limited
liability company to a "C" corporation under the Code, the issued and
outstanding PriceLine Units owned by the Employee shall be converted into the
number of shares of stock of the successor corporation that is necessary for the
Employee to own the same percentage of the issued and outstanding stock of such
corporation immediately after such conversion as the Employee owned of the
issued and outstanding PriceLine Units immediately prior to such conversion. 

                      (iii)  In the event that PriceLine sells all or a
substantial portion of its assets outside of the ordinary course of business,
then the Employee shall be paid, as additional compensation, an amount equal to
the excess, if any, of (A) an amount equal to what would have been his "pro
rata" share of the net proceeds available for distribution to all holders of
PriceLine Units (calculated as if all holders of PriceLine Units were to receive
distributions strictly in accordance with the number of PriceLine Units
outstanding and owned by each member of PriceLine) over (B) the amount available
for distribution to him under the terms of the PriceLine LLC Agreement.  

          4.   BUSINESS EXPENSES.  The Employee shall be reimbursed for all
direct, out-of-pocket business expenses incurred by him in connection with his
employment (including, without limitation, expenses for travel and entertainment
incurred in conducting or promoting business for the Companies) upon timely
submission by the Employee of receipts and other documentation as required by
the Code and in accordance with the normal expense reimbursement policies of the
Companies.

          5. TERMINATION.

          (a)  DEATH.  The employment by the Companies of the Employee pursuant
to this Agreement shall be terminated upon the death of the


                                          9

          7.   LIMITATION ON TRANSFER OF SECURITIES.

          (a)  The Employee shall not, directly or indirectly, offer, transfer,
sell, assign, pledge, encumber, hypothecate or otherwise dispose of all or part
of the securities issued pursuant to this Agreement or solicit any offers to
purchase or otherwise acquire or take a pledge of all or part of such securities
without the prior written consent of the issuer of such securities, PROVIDED,
HOWEVER, the foregoing restrictions shall not apply to the securities of an
issuer that has issued common equity securities in a public offering pursuant to
an effective registration statement under the Securities Act of 1933, as amended
(the "Act"), other than a registration statement filed on Form S-8, or any
successor form thereto, or any other applicable form with respect to the

child, other descendant or any other United States citizen, PROVIDED such person
is reasonably satisfactory to the Stockholder, or to a trust established for the

Permitted Transferees shall agree in writing to be bound by the terms of this
Agreement, a copy of which writing shall be filed with the issuer of such
securities and (ii) any such securities so transferred shall continue to be
subject to this Agreement.

          (d)  The Employee acknowledges that he is aware that there are
substantial restrictions on the transferability of the securities issued
pursuant to this Agreement.  In addition to the restrictions set forth above,
since the securities issued pursuant to this Agreement will not be, and the
Employee has no right to require that such securities be, registered under the

Employee shall be responsible for compliance with all conditions on transfer

     ENCUMBRANCE, HYPOTHECATION OR OTHER DISPOSITION COMPLIES WITH THE
     PROVISIONS OF THE EMPLOYMENT AGREEMENT DATED AS OF JANUARY 1, 1997. 
     IN ADDITION TO THE RESTRICTIONS ON TRANSFER SET FORTH IN SUCH
     AGREEMENT, NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, ENCUMBRANCE,
     HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY
     THIS CERTIFICATE

     MAY BE MADE EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS
     IN EFFECT THEREUNDER (THE "ACT"), AND ALL APPLICABLE STATE SECURITIES OR
     "BLUE SKY" LAWS OR (B) IF SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE,
     ENCUMBRANCE, HYPOTHECATION OR OTHER DISPOSITION IS EXEMPT FROM THE
     PROVISIONS OF THE ACT AND, IF REQUIRED BY THE COMPANY, THE COMPANY HAS BEEN
     FURNISHED WITH AN OPINION OF COUNSEL FOR THE HOLDER, WHICH OPINION AND
     COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE COMPANY, TO THAT EFFECT. 
     THE HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE, AGREES
     TO BE BOUND BY ALL OF THE PROVISIONS OF THE AFORESAID AGREEMENT.

          8.   CONFIDENTIALITY; NON-COMPETITION.  As a condition to the
Companies' and the Stockholder's willingness to enter into this Agreement and in
partial consideration of the grant of the Options, the Employee agrees to the
covenants and restrictions set forth in this Section 8.

          (a)  The Employee agrees that, during the Term and for a period of two
(2) years thereafter, he shall not, directly or indirectly, induce or solicit
(or authorize or assist in the taking of any such actions by any third party)
any employee or consultant of the Companies to leave his or her business
association with the Companies.

          (b)  The Employee acknowledges and agrees that, during the course of
the provision of the Employee's services to the Companies, the Employee may be
exposed to confidential, proprietary or sensitive data and information
concerning the business and affairs of the Companies, and that all such data and
information constitutes a protectable business interest of the Companies.  In
furtherance of such business interest, the Employee is contemporaneously
herewith executing and delivering to Walker Digital and PriceLine the standard
consultant confidentiality agreement of each of them (the "Confidentiality
Agreements").

          (c)  The Employee agrees that he will not at any time during the Term
and, (i) for a period of one (1) year following the Date of Termination, di-


                                          15
<PAGE>

rectly or indirectly, own any interest in, operate, join, control or participate
as a director, stockholder, owner, partner, principal, officer or agent of,
enter into the employment of, act as a consultant to, or perform any services
for, any entity that is engaged anywhere in the United States of America in any
business in which either of the Companies is presently engaged.  Notwithstanding
anything herein to the contrary, this Section 8 shall not prevent the Employee
from acquiring securities representing not more than one percent (1%) of the
outstanding voting securities of any publicly held corporation.  It is the
desire and intent of the parties that the provisions of this Section 8(c) shall
be enforced to the fullest extent permitted under applicable law.  If all or
part of this Section 8(c) is held invalid, illegal or incapable of being
enforced by any law or public policy, all other terms and provisions of this
Agreement shall nevertheless remain in full force and effect.  If any part of
this Section 8(c) is ultimately determined to be excessively broad as to
duration, scope, activity or subject, such part will be construed by limiting
and reducing it so as to be enforceable to the maximum extent compatible with
applicable law. 

          (d)  The Employee acknowledges and agrees that each of the covenants
set forth in this Section 8 and in the Confidentiality Agreements are reasonable
and necessary for the protection of the Companies' business interests, that
irreparable injury will result to the Companies if the Employee breaches any of
the terms of said covenants, and that in the event of the Employee's actual or
threatened breach of any such covenants, the Companies will have no adequate
remedy at law.  The Employee accordingly agrees that in the event of any actual
or threatened breach by the Employee of any of said covenants, the Companies
shall be entitled to immediate injunctive and other equitable relief without
bond and without the necessity of showing actual monetary damages.  Nothing
contained herein shall be construed as prohibiting the Companies from pursuing
any other remedies available to it for such breach or threatened breach,
including the recovery of any damages which it is able to prove.

          (e)  The provisions of this Section 8 shall survive the expiration or
termination of this Agreement, and any of the arrangements contained herein, and
shall be binding upon the Employee's corporate or personal successors and
assigns.

          9.   INDEMNIFICATION.   In the event the Employee was, is or becomes a
party to or witness or other participant in, or is threatened to be made a party
to or witness or other participant in, any threatened, pending or completed 


                                          16
<PAGE>

action, suit or proceeding, or any inquiry or investigation (whether instituted
by the Companies or any other party) that the Employee in good faith believes
might lead to the institution of any such action, suit or proceeding, whether
civil, criminal, administrative, investigative or otherwise (a "Claim"), by
reason of (or arising in part out of) any event or occurrence related to the
fact that the Employee is or was a director, officer, employee, agent,
independent contractor, consultant or fiduciary of either of the Companies, or
is or was serving at the request of either of the Companies as a director,
officer, employee, trustee, agent, independent contractor, consultant or
fiduciary of another corporation, partnership, limited liability company, joint
venture, employee benefit plan, trust or other enterprise, or by reason of
anything done or not done by the Employee in any such capacity (an
"Indemnifiable Event"), then the Companies, jointly and severally, shall
indemnify and hold harmless the Employee to the fullest extent permitted by law
as soon as practicable but in any event no later than thirty (30) days after
written demand is presented to the Companies, against any and all expenses
(including attorneys' fees), judgments, fines, penalties and amounts paid in
settlement (including all interest, assessments and other charges paid or
payable in connection with or in respect of such expenses, judgments, fines,
penalties or amounts paid in settlement of such Claim.  If so requested by the
Employee, the Companies shall advance (within two (2) business days of such
request) to the Employee any and all expenses (including attorneys' fees)
incurred by the Employee in connection with any Claim relating to an
Indemnifiable Event, upon the receipt of an undertaking by or on behalf of the
Employee to repay such amounts if it shall ultimately be determined that he is
not entitled to be indemnified by the Companies as authorized in this Section 9.
Notwithstanding anything contained herein to the contrary, the indemnification
obligations of the Companies set forth in this Section 9 shall survive the
termination or expiration of this Agreement.

          10.  SUCCESSORS; BINDING AGREEMENT.  This Agreement is a personal
contract and the rights and interests of the Employee hereunder may not be sold,
transferred, assigned, pledged, encumbered or hypothecated by him, except as

Agreement may be amended, modified or waived unless such amendment, modification
or waiver is agreed to in writing, signed by the Employee, the Stockholder and a
duly authorized officer of each of the Companies.  No waiver by any party hereto

any subsequent time.

          (c)  If any dispute arising under this Agreement is not settled

                                          20

from the lists submitted by the AAA, then the Employee, on the one hand, and the

          (c)  Notwithstanding the foregoing, no provision hereof is intended to
prohibit the transfer of the securities issued pursuant to this Agreement (i)
upon the death of the Employee, by operation of laws of inheritance and descent
to the Employee's personal representatives, executors, administrators,
testamentary trustees, legatees or beneficiaries or (ii) by gift to a spouse,
child, other descendant or any other United States citizen, PROVIDED that such
person is reasonably satisfactory to PriceLine, or to a trust established for
the benefit of such person (each transferee referred to in clause (i) or (ii)
being a "Permitted Transferee"); and  PROVIDED, FURTHER, that (i) any and all
such Permitted Transferees shall agree in writing to be bound by the terms of
this Agreement, a copy of which writing shall be filed with the issuer of such
securities and (ii) any such securities so transferred shall continue to be
subject to this Agreement.

          (d)  The Employee acknowledges that he is aware that there are
substantial restrictions on the transferability of the securities issued
pursuant to this Agreement.  In addition to the restrictions set forth above,
since the securities issued pursuant to this Agreement will not be, and the
Employee has no right to require that such securities be, registered under the
Act, such securities may not be sold unless such sale is exempt from such
registration under the Act.  The undersigned further acknowledges that the
Employee shall be responsible for compliance with all conditions on transfer
imposed by any state "blue sky" or securities law administrator.

          (e)  Each certificate representing the securities (other than the
PriceLine Option) issued to the Employee pursuant to this Agreement shall bear
substantially the following legend:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED,
     SOLD, ASSIGNED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE
     DISPOSED OF UNLESS SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE,
     ENCUMBRANCE, HYPOTHECATION OR OTHER DISPOSITION COMPLIES WITH THE
     PROVISIONS OF THE EMPLOYMENT AGREEMENT DATED AS OF JULY __, 1998.  IN
     ADDITION TO THE RESTRICTIONS ON TRANSFER SET FORTH IN SUCH AGREEMENT,
     NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, ENCUMBRANCE, HYPOTHECATION OR
     OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE
     MAY BE MADE EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND
     REGULATIONS IN EFFECT THEREUNDER (THE "ACT"), AND ALL APPLICABLE STATE
     SECURITIES OR "BLUE SKY" LAWS OR (B) IF SUCH TRANSFER, SALE,
     ASSIGNMENT, PLEDGE, ENCUMBRANCE, HYPOTHECATION OR OTHER DISPOSITION IS
     EXEMPT FROM THE PROVISIONS OF THE ACT AND, IF REQUIRED BY THE COMPANY,
     THE COMPANY HAS BEEN FURNISHED WITH AN OPINION OF COUNSEL FOR THE
     HOLDER, WHICH OPINION AND COUNSEL SHALL BE REASONABLY SATISFACTORY TO
     THE COMPANY, TO THAT EFFECT.  THE HOLDER OF THIS CERTIFICATE, BY
     ACCEPTANCE OF THIS CERTIFICATE, AGREES TO BE BOUND BY ALL OF THE
     PROVISIONS OF THE AFORESAID AGREEMENT.

          8.   CONFIDENTIALITY; NON-COMPETITION.  As a condition to PriceLine's
willingness to enter into this Agreement and in partial consideration of the
grant of the Option, the Employee agrees to the covenants and restrictions set
forth in this Section 8.


                                          10
<PAGE>

          (a)  The Employee agrees that, during the Term and for a period of two
(2) years thereafter, he shall not, directly or indirectly, induce or solicit
(or authorize or assist in the taking of any such actions by any third party)
any employee or consultant of PriceLine or PriceLine Travel or any of their
affiliates to leave his or her business association with such entity.

          (b)  The Employee acknowledges and agrees that, during the course of
the provision of the Employee's services to PriceLine and PriceLine Travel, the
Employee may be exposed to confidential, proprietary or sensitive data and
information concerning the business and affairs of PriceLine and PriceLine
Travel, and that all such data and information constitutes a protectable
business interest of PriceLine and PriceLine Travel.  In furtherance of such
business interest, the Employee is contemporaneously herewith executing and
delivering to PriceLine the standard consultant confidentiality agreement
PriceLine (the "Confidentiality Agreement").

          (c)  The Employee agrees that he will not at any time during the Term
and, (i) for a period of one (1) year following the Date of Termination,
directly or indirectly, own any interest in, operate, join, control or
participate as a director, stockholder, owner, partner, principal, officer or
agent of, enter into the employment of, act as a consultant to, or perform any
services for, any entity that is engaged anywhere in the United States of
America in a business substantially similar to PriceLine or PriceLine Travel
whereby customers are directed to make an offer to purchase goods and services
and such demand is provided to potential sellers.  Notwithstanding anything
herein to the contrary, this Section 8 shall not prevent the Employee from
acquiring securities representing not more than one percent (1%) of the
outstanding voting securities of any publicly held corporation.  It is the
desire and intent of the parties that the provisions of this Section 8(c) shall
be enforced to the fullest extent permitted under applicable law.  If all or
part of this Section 8(c) is held invalid, illegal or incapable of being
enforced by any law or public policy, all other terms and provisions of this
Agreement shall nevertheless remain in full force and effect.  If any part of
this Section 8(c) is ultimately determined to be excessively broad as to
duration, scope, activity or subject, such part will be construed by limiting
and reducing it so as to be enforceable to the maximum extent compatible with
applicable law. 

          (d)  The Employee acknowledges and agrees that each of the covenants
set forth in this Section 8 and in the Confidentiality Agreement are reasonable
and necessary for the protection of PriceLine's and PriceLine Travel's


                                          11
<PAGE>

business interests, that irreparable injury will result to PriceLine and
PriceLine Travel if the Employee breaches any of the terms of said covenants,
and that in the event of the Employee's actual or threatened breach of any such
covenants, PriceLine and PriceLine Travel will have no adequate remedy at law. 
The Employee accordingly agrees that in the event of any actual or threatened
breach by the Employee of any of said covenants, PriceLine and PriceLine Travel
shall be entitled to immediate injunctive and other equitable relief without
bond and without the necessity of showing actual monetary damages. 
Notwithstanding the provisions of Section 15 hereof, such equitable relief may
be sought in any court of competent jurisdiction.  Nothing contained herein
shall be construed as prohibiting PriceLine from pursuing any other remedies
available to it for such breach or threatened breach, including the recovery of
any damages which it is able to prove.

          (e)  The provisions of this Section 8 shall survive the expiration or
termination of this Agreement, and any of the arrangements contained herein, and
shall be binding upon the Employee's corporate or personal successors and
assigns.


          9.   SUCCESSORS; BINDING AGREEMENT.  This Agreement is a personal
contract and the rights and interests of the Employee hereunder may not be sold,
transferred, assigned, pledged, encumbered or hypothecated by him, except as
otherwise expressly permitted by the provisions of this Agreement.  This
Agreement shall inure to the benefit of the parties hereto and their respective
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.

          10.  ENTIRE AGREEMENT.  This Agreement and the Confidentiality
Agreement contain all of the understandings between the parties hereto
pertaining to the matters referred to herein, and supersedes any other
undertakings and agreements, whether oral or in writing, previously entered into
by them with respect thereto.  The Employee represents that, in executing this
Agreement, he does not rely and has not relied upon any representation or
statement not set forth herein made by PriceLine with regard to the subject
matter or effect of this Agreement or otherwise.

          11.  AMENDMENT, MODIFICATION AND WAIVER.  No provision of this
Agreement may be amended, modified or waived unless such amendment, modifi-


                                          12
<PAGE>

cation or waiver is agreed to in writing, signed by the Employee and a duly
authorized officer of PriceLine.  No waiver by any party hereto of any breach by
another party hereto of any condition or provision of this Agreement to be
performed by such other party shall be deemed a waiver of a similar or
dissimilar condition or provision at the same time, any prior time or any
subsequent time.

          12.  NOTICES.  Any notices, requests, demands, waivers or other
communications required or permitted to be given hereunder shall be in writing

                                          13
<PAGE>

this Agreement not so held invalid, and all other such provisions shall to the
full extent consistent with law continue in full force and effect.  If any such

full force and effect.

          14.  SURVIVORSHIP.  The respective rights and obligations of the
parties hereunder shall survive any termination of this Agreement to the extent

          15.  GOVERNING LAW; JURISDICTION; ARBITRATION.

          (a)  This Agreement will be governed by and construed in accordance
with the laws of the State of Connecticut, without regard to its conflicts of
laws principles.

          (b)  The parties hereto hereby irrevocably:

               (i)  agree that any suit, action or other legal proceeding
arising out of this Agreement, or any of the transactions contemplated hereby,
may be brought in the courts of record of the State of Connecticut or the courts
of the United States located in the State of Connecticut;

               (ii) consent to the jurisdiction of each such court in any such
suit, action or proceeding;

               (iii)     waive any objection to the laying of venue of any such
suit, action or proceeding in any of such courts; and

               (iv) agree that Connecticut is the most convenient forum for
litigation of any such suit, action or proceeding.

          (c)  If any dispute arising under this Agreement is not settled
promptly in the ordinary course of business, the parties shall seek to resolve
any such dispute between them, first, by negotiating promptly with each other in
good faith.  If the parties are unable to resolve the dispute between them
within twenty (20) business days (or such period as the parties shall otherwise
agree) through these negotiations, then any such disputes shall be settled by
binding arbitration in accordance with this Agreement and the following
procedures:


                                          14
<PAGE>

               (i)  Any arbitration shall be conducted in accordance with the
Commercial Rules of the American Arbitration Association (the "AAA") then in
effect.

               (ii) Either party shall serve upon the other parties a written
demand that the dispute be arbitrated, specifying in reasonable detail the
nature of the dispute to be submitted to arbitration.

               (iii)     Within thirty (30) days after service of a demand for
arbitration, the parties shall attempt to agree upon a single arbitrator.

               (iv) In the event the parties cannot agree upon a single
arbitrator, any party may request the AAA to appoint an arbitrator in accordance
with its rules; except that if the parties fail to agree upon an arbitrator from
the persons named by the AAA or if for any reason the appointment cannot be made
from the lists submitted by the AAA, then the Employee and PriceLine shall each
appoint an arbitrator within seven (7) days thereafter and the third arbitrator
shall be appointed by the AAA.

               (v)  The arbitration proceeding shall be held in Stamford,
Connecticut.

               (vi) The arbitrators shall have no power or authority to add to
or detract from the agreements of the parties.  The arbitrators shall have no
authority to award punitive, exemplary, consequential, special, indirect or
incidental damages.

               (vii)     The expenses of arbitration shall be borne equally by
the Employee and PriceLine unless the arbitrators determine that one of the
parties has not proceeded in good faith with respect to the matters submitted
for arbitration, in which case, such party shall bear fully the expenses of
arbitration.

               (viii)    Judgment may be entered on any arbitration award in any

this Agreement are intended solely for convenience, and no provision of this
Agreement is to be construed by reference to the heading of any section or
paragraph.

          17.  SPECIFIC PERFORMANCE.  Each party hereto acknowledges that money

this Agreement by such party and that any such breach would cause the other
parties irreparable harm.  Accordingly, each party hereto also agrees that, in
the event of any breach or threatened breach of the provisions of this Agreement
by such party, the other parties shall be entitled to equitable relief without
the requirement of posting a bond or other security, including in the form of
injunctions and orders for specific performance, in addition to all other
remedies available to such other parties at law or in equity.

          18.  COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

               the Launch Date,".

          2.   VESTING OF PRICELINE OPTION.  The Employee and PriceLine agree

               Agreement shall remain in full force and effect; PROVIDED,
               HOWEVER, that in the event that any term or condition of this

               contrary to, any term or provision of the Employment Agreement,
               then the terms and provisions of the Amendment shall control.

          IN WITNESS WHEREOF, the parties have executed and delivered this
Amendment on the date indicated above.

                                   WITNESSETH

          WHEREAS, PriceLine provides an electronic service via the Internet
that allows consumers to purchase airline tickets at an offer price determined
by the consumer (the "PriceLine Service"). The consumer identifies the origin
and destination and departure and return dates for travel and the price the

are available at an appropriate price. If such seats are available, PriceLine
Travel will issue a ticket on the applicable carrier.

          WHEREAS, The Airline desires to participate in the PriceLine Service
and, in connection therewith, will provide access to the Airline's inventory at
pricing for the origin and destination pairs (each, an "O&D") as determined by
the Airline in accordance with the terms and conditions set forth in this
Agreement.

          WHEREAS, PriceLine desires to include the Airline as a participating
carrier in the PriceLine Service and to have access to such inventory in
accordance with the terms and conditions set forth in this Agreement.

          NOW, THEREFORE, in consideration of the covenants and agreements set
forth in this Agreement, the parties agree as follows:

one of the major U.S. full service airlines or, in the case of international
travel, other airline carriers available through the PriceLine Service. The

The Airline shall maintain and communicate any changes in fares and/or rules to
be used by PriceLine. The Airline will file base fares (i.e. not fares) via
ATPCO (Airline Tariff Publishing Corporation). The base fare is the Unpublished
Fare net of any taxes required to be paid by a customer as part of the purchase
of a ticket from PriceLine under Section 4261(a) and 4261(e)(5) of the Code.
ATPCO will transmit the base fares to WorldSpan and WorldSpan will add in the
Section 4261 Taxes. These fares will be secured to the PriceLine IATA number.

The Airline may file fare and/or rule changes up to 3 times a day Mon-Fri and
once a day on weekends. The Airline will consider PriceLine notified of any
changes when WorldSpan has completed loading the ATPCO file. The following chart
illustrates the approximate filing times:

                  CONFIDENTIAL TREATMENT HAS BEEN REQUESTED FOR
                 CERTAIN PORTIONS OF THIS DOCUMENT. CONFIDENTIAL
                    PORTIONS HAVE BEEN FILED SEPARATELY WITH
                     THE SECURITIES AND EXCHANGE COMMISSION.


                                GENERAL AGREEMENT

         This General Agreement (this "AGREEMENT"), dated August 31, 1998, is by
and among priceline.com Incorporated, a Delaware corporation with an address at
Five High Ridge Park, Stamford, Connecticut 06905 ("PRICELINE INC."), PriceLine
Travel, Inc., a Delaware corporation with an address at 5 High Ridge Park,
Stamford, Connecticut 06905 ("PRICELINE TRAVEL" and, together with Priceline
Inc., being collectively referred to herein as "PRICELINE"), and Delta Air
Lines, Inc., a Delaware corporation, having a principal place of business at
1030 Delta Boulevard, Hartsfield Atlanta International Airport, Atlanta, Georgia
30320 ("DELTA").

                                    RECITALS:

         Delta is a major carrier providing scheduled air transportation
services to domestic and international destinations. Priceline provides a
service that allows consumers to purchase airline tickets at an offer price
determined by the consumer (the "PRICELINE SERVICE").

         Priceline desires that Delta become a participating carrier in the
Priceline Service pursuant to the terms of this Agreement and two related
agreements dated as of the date hereof between Delta and Priceline: (i) a
Participating Carrier Agreement (the "PCA") and (ii) a Participation Warrant
Agreement (the "PWA") (this Agreement, the PCA and the PWA are collectively
referred to herein as the "Transaction Documents"). Delta desires to participate
in the Priceline Service, subject to the terms and conditions set forth in the
Transaction Documents.

         In consideration of the covenants and agreements set forth in the
Transaction Documents, the parties agree as follows:

1.       DEFINITIONS


[**] = Confidential treatment requested for redacted portion.


<PAGE>


         As used in this Agreement, terms with their initial letters capitalized
         (or otherwise defined) shall have the meanings assigned to them in this
         Agreement or, if not defined herein, the meanings assigned in the
         other Transaction Documents.

2.       TEST AND EVALUATION OF PRICELINE SERVICE

         2.1       Delta will make available a limited number of unpublished
                   fares to Priceline in select origin and destination city
                   pairs identified by Delta for a test period. The test period
                   shall begin following the execution of this Agreement and
                   continue thereafter for a period of not greater than 60 days
                   (the "TEST PERIOD").

         2.2       The purpose of the Test Period is to permit Delta to test and
                   evaluate the Priceline Service, and address staffing and
                   technical issues prior to the implementation of Delta's full
                   participation in the Priceline Service.

         2.3       During the Test Period, and following the successful
                   completion of the Test Period, Delta's participation in
                   Priceline will be subject to the terms of the Transaction
                   Documents.

         2.4       At the close of the Test Period, Delta will notify Priceline
                   as to its determination of whether the test of Delta's
                   participation in the Priceline Service is successful, which
                   determination shall be binding on Priceline.

                   (i)  If the test is successful, then Delta shall continue its
                        participation in the Priceline Service in accordance
                        with the terms of the Transaction Documents.

                   (ii) If the test is not successful, then the parties shall
                        meet to determine if any modification to the Priceline
                        Service or Delta's participation can be made to cause
                        Delta's participation to be successful. If no agreement
                        can be reached then, notwithstanding any provision to
                        the contrary in the Transaction Documents, Delta or
                        Priceline may terminate the Transaction Documents on
                        written notice to the other party. Delta and

[**] = Confidential treatment requested for redacted portion.


                                        2

<PAGE>


                        Priceline agree that, if Delta determines that the test
                        is not successful and the Transaction Documents are
                        terminated, then neither Delta nor Priceline will claim
                        any damages against the other, and each party will
                        return all Confidential Information to the disclosing
                        party.

3.       CARRIER PARTICIPATION, CHANGES TO RESTRICTIONS AND SOFTWARE LICENSE

         Subject to Section 3.5 below, Delta and Priceline agree that, during
         the term of the PCA:

         3.1       (i) all airlines which have signed an agreement with
                   Priceline to participate in the Priceline Service as of the
                   date hereof (as identified in the attached Schedule 3.1
                   hereof) may continue such participation; (ii) for a six (6)
                   month period following the completion of the Test Period (the
                   "TRANSITION PERIOD") Priceline will not add any additional
                   airlines to the Priceline Service without Delta's prior
                   written consent; PROVIDED, HOWEVER, that Delta agrees to
                   consent to the inclusion (on a test basis with Delta's
                   approval of the test O&D markets) of any one additional
                   carrier with a domestic market share greater than [**] [as
                   measured in revenue passenger miles reported on U.S.
                   Department of Transportation ("DOT") Form 41 ("RPMS")] if
                   such carrier's participation is limited to an extent that
                   its participation, in Delta's reasonable business judgment,
                   will not interfere with Delta's evaluation of the Priceline
                   Service during the Transition Period; (iii) Priceline will
                   use its best efforts to recruit [**] as a Priceline Service
                   participant prior to the inclusion of any other major
                   airline, excepting [**]; and (iv) after the Transition
                   Period, Priceline may add additional U.S. domestic carriers
                   to the Priceline Service which are acceptable to Delta (as
                   reflected by Delta's written consent), with a goal of 
                   including in the Priceline Service a total number of 
                   domestic airline participants so that the sum total 
                   domestic market share of all such participating airlines 
                   will, in an annual measuring period, represent [**] of all 
                   U.S. domestic RPMs (the "RANGE"). Notwithstanding the 
                   foregoing, but subject in all cases to the Range, Priceline
                   may, (x) during and after the Transition Period, include 
                   in the Priceline Service [**]; (y) following the Transition 
                   Period, Delta may require, as a condition to the inclusion 
                   in the Priceline Service of any additional U.S. domestic

                   carrier which has a domestic market share of greater than
                   [**] of U.S. domestic RPMs, the exclusion of specific markets
                   (including cities served to/from specified airports) from
                   such carrier's participation, and (z) the inclusion of
                   additional international carriers in the Priceline Service
                   will be subject to the prior written approval of Delta.

         3.2       All Priceline Tickets issued on Delta and all other airlines
                   participating in the Priceline Service (the "PARTICIPATING
                   CARRIERS") shall be subject to the Restrictions.

         3.3       If during any two consecutive months during the term of the
                   PCA, the number of Priceline Tickets sold on Participating
                   Carriers that do not include a Saturday night stay is greater
                   than 10% of all Priceline Tickets sold on Participating
                   Carriers during such period, then Priceline shall include and
                   shall require as part of the Restrictions a Saturday night
                   stay for all Priceline Ticket sales.

         3.4       LICENSE OF PRICELINE SOFTWARE. In the event that one of the
                   eight largest U.S. airlines or five largest foreign flag
                   carriers (measured in each case using total revenue passenger
                   miles) offers a service that allows consumers to purchase
                   airline tickets at an offer price determined by the consumer
                   that is comparable to the Priceline Service, then Priceline
                   will, at Delta's request, grant to Delta a non exclusive
                   license to independently use the software developed by
                   Priceline for the Priceline Service (the "PRICELINE
                   SOFTWARE"') and, if requested by Delta, will operate the

                   Section 3.4, (i) Priceline will not sell, transfer, license

                   commercially reasonable terms that are no less favorable
                   than those offered to any other participating airline, (y)
                   agrees that the Restrictions shall apply to any flights to or
                   from the United States, and (z) does not, directly or
                   indirectly, through an affiliate or otherwise, have an 
                   existing contractual or agency relationship with Delta. 
                   Further, insofar as Priceline licenses or operates the 
                   Priceline Software to or for the benefit of any other party, 
                   any license or operation of the Priceline Software to or for
                   the benefit of Delta as permitted by this Section 3.7 shall 
                   be on no less favorable terms and conditions than those 
                   granted by Priceline to any such third party. In addition, 
                   any sale, transfer or license of the Priceline Software 
                   shall restrict the third party from selling, transferring, 
                   licensing or operating the software for the use or benefit 
                   of any Travel Company. As used herein, the term "Priceline 
                   Software" shall include, without limitation, materials, 
                   databases, development environment, modifications and 
                   associated intellectual property pertaining to embodied in,
                   comprising, used or necessary for the operation or support 
                   of the Priceline Software or its derivative works.

         3.5       LIMITATION ON SECTION 3 RIGHTS. The rights of Delta as set
                   forth in Sections 3.1-3.4 above and any license or operation
                   of the Priceline Software granted or provided by Priceline
                   under Section 3.4 shall automatically terminate, and shall be
                   of no further force or effect, in the event that Delta fails
                   to achieve the "MINIMUM THRESHOLD." For the period beginning
                   January 1, 1999 through December 31, 2004, Delta will fail to
                   achieve the Minimum Threshold if domestic Priceline Tickets
                   sold on Delta are (i) less than [**] and (ii) constitute less
                   than [**] of total domestic U.S. Priceline Ticket sales on
                   all airlines (including Delta), in each case during any two
                   consecutive calendar quarters commencing with the calendar
                   quarter beginning January 1, 1999. For the period beginning
                   January 1, 2005 through December 31, 2009, Delta will fail to
                   achieve the Minimum Threshold if Priceline Tickets sold for
                   travel on Delta constitute less than [**] of total domestic
                   U.S. Priceline Ticket sales on all airlines (including
                   Delta), in each case during any two consecutive calendar
                   quarters commencing with the calendar quarter beginning
                   January 1, 2005. For purposes of this section, sales on Delta
                   shall include sales

                   on Delta and its code share partners. Notwithstanding the
                   foregoing, Delta shall continue to enjoy the rights granted
                   under Sections 3.1-3.4 above if this Agreement (or the PCA)
                   is terminated solely as a result of Priceline's material
                   breach (which breach was not cured as required by Paragraph
                   VIII.2 of the PCA), and Delta has met the Mini mum Threshold
                   as required by this Section 3.5. In calculating the dollar
                   amount and percentage amount specified in this Section 3.5,
                   in the event that an additional U.S. domestic carrier is
                   added as a Participating Carrier any time after the date
                   hereof and during the term of this Agreement, the parties
                   agree that the Minimum Threshold shall be reduced
                   proportionately to reflect the proportionate decrease in
                   Delta's resulting U.S. domestic market share as compared with
                   all other Participating Carriers. The dollar and/or
                   percentage amount shall be adjusted upon the admission of an
                   additional U.S. domestic carrier by multiplying such amount
                   by a fraction, the numerator of which shall be Delta's U.S.
                   domestic RPMs and the denominator of which shall be Delta's
                   U.S. domestic RPMs and the aggregate U.S. domestic RPMs of
                   the new additional U.S. domestic carrier and all other U.S.
                   domestic Participating Carriers. During the period of any
                   Force Majeur Event, the measuring periods herein shall be
                   extended by one day for each day of such Force Majeur Event.
                   For purposes of the Transaction Documents, if DOT Form 41 is
                   discontinued, such measurement will be based on domestic
                   revenue passenger miles as reported in industry publications.

4.       CONFIDENTIAL

         The confidentiality provisions of the PCA shall fully apply to this
         Agreement as if set forth herein and shall remain in force during the
         term of this Agreement.

5.       PROPRIETARY MARKS

         This Agreement shall not be construed to give Priceline or Delta the
         right to use the other party's trademarks, trade names, service marks,
         logos, emblems, symbols or other brand identifiers in advertising or
         marketing materials, without the prior written approval of the other
         party.

6.       TERM OF AGREEMENT

         6.1       This Agreement will commence on the date set forth above and
                   will continue for the term of the PCA.

         6.2       The obligations of the parties under Sections 4 and 8 of this
                   Agreement shall indefinitely survive the expiration or any
                   termination of this Agreement.

7.       PCA RELATED MATTERS

         Unless otherwise agreed in writing by Delta and Priceline, during the
         term of the PCA:

         7.1       Priceline shall use reasonable best efforts to include
                   Delta's marketing partners (as identified by Delta from time
                   to time) in any packaged tour, hotel and/or rental car
                   services or products offered by Priceline through the
                   Priceline Service on terms and conditions no less favorable
                   than those offered to any other competing participant.

         7.2       Priceline agrees to fulfill all Priceline ticket requests
                   allocable to Delta under the first look and second look as
                   set forth in Paragraph III of the PCA, at the "Highest
                   Qualifying Fare" available from Delta. As used herein, the
                   term "HIGHEST QUALIFYING FARE" means the highest priced Delta
                   unpublished fare meeting the Priceline customer's offer price
                   and other terms, plus the amount of Priceline's minimum
                   ticket sale margin as established from time to time by
                   Priceline and notified to Delta.

         7.3       All Priceline tickets sold on Delta will be settled through
                   ARC; provided, the parties agree to work diligently and in
                   good faith to establish and implement a direct settlement
                   arrangement between PriceLine Travel and Delta within six
                   months following the completion of the Test Period.

         7.5       Priceline will require Participating Carriers to file
                   unpublished fares for Priceline Tickets through the WORLDSPAN
                   CRS; provided, Delta will have the option to file its fares
                   through Delta's internal reservation system, provided
                   further, that, on an exception basis where necessary to
                   obtain the participation of a carrier that has an ownership
                   interest in a competing CRS, Priceline may offer such
                   carrier(s) the opportunity to file unpublished fares for
                   Priceline Tickets through a competing CRS.

         7.6       If Delta provides Priceline with access to Delta's
                   unpublished fares through WORLDSPAN, Priceline shall work
                   with Delta to reach a satisfactory arrangement with respect
                   to the exclusion of Priceline reservation and booking data on
                   Delta from WORLDSPAN's B-IDT/MIDT data compilations.

         7.7       [**]

         7.8       Priceline shall not advertise prices or fares in any O&D
                   below Delta's published fares in the applicable O&D.

         7.9       In the event that Priceline is unable to fulfill a Priceline
                   ticket request from unpublished fares and seat inventory
                   provided from Participating Carriers, and Priceline decides
                   to purchase an airline ticket using a published fare, then
                   Priceline shall purchase the published fare from
                   Participating Carriers based on a formula which allocates
                   such purchases in proportion to the aggregate domestic or
                   international market share (as applicable) offered by each
                   Participating Carrier in the O&D requested; provided, that
                   the Participating Carrier has seats available for sale at
                   published fares comparable to the published fares available
                   from other Participating Carriers in such O&D.

         7.10      At the request of Delta, Priceline will incorporate into the
                   Priceline Service a "hot link" to the designated Internet
                   site of Delta; PROVIDED, HOWEVER, that Priceline will have a
                   reasonable period of time following any such request to
                   accomplish any system changes, additions or enhancements
                   necessary or appropriate for the inclusion of any such "hot
                   link."

         7.11      Participating Carriers will be given the first opportunity to
                   fill a customer ticket request based on a formula [**]. If a
                   Participating Carrier fails to respond to a ticket request on
                   its designated first look, then Priceline will allocate the
                   request through a second round of preferred looks [**] for
                   each O&D requested (but excluding the Participating Carrier
                   that failed to fulfill the ticket request on the first look).

         7.12      REVENUE SHARING. If Priceline's total margin (defined as
                   Priceline Ticket sales on Delta net of payments to Delta and
                   applicable credit card merchant fees) on aggregate ticket
                   sales of Delta exceeds 12% (the "EXCESS REVENUE"), for any
                   calendar quarter during the term of the PCA, Priceline will
                   pay Delta a percentage of such Excess Revenue based on the
                   following formula:

<TABLE>
<CAPTION>

             If Revenue for the         Priceline will pay as a Commission
          Quarter is greater than:          the following percentage:
          ------------------------          ------------------------
<S>                                         <C>
              $[**] million                          [**]%
              $[**] million                          [**]%
              $[**] million                          [**]%
              $[**] million                          [**]%
          $[**] million or greater                   [**]%

</TABLE>

                   Within 15 days after the close of each such calendar quarter,
                   Priceline will remit to Delta the amount payable to Delta
                   under this Section 7.12, which amount shall be accompanied by
                   Priceline's calculation of Excess Revenue for the period in
                   question.

         7.13      Priceline will provide Delta with a daily electronic report
                   in a format designated by Delta, summarizing, information
                   concerning Priceline customer offers that were not fulfilled
                   by Delta, including (i) O&D requested, (ii) offer price and
                   (iii) number of offers at each offer price; such reports to
                   begin within 30 days following the initiation of the Test
                   Period.

         8.1       For purposes of this Section 8, "LOSSES" shall mean any and
                   all costs, demands, losses, claims (including any claim by a
                   third party), liabilities, fines, penalties, assessments,
                   damages, including, without limitation, interest, penalties,
                   reasonable attorneys' fees and expenses and all amounts paid
                   in proceedings, claims, complaints, disputes, arbitrations,
                   investigations, defense or settlement of any of the
                   foregoing.

         8.2       Except as otherwise provided in this Article 8, Delta agrees
                   to indemnify, defend and hold harmless Priceline and its
                   affiliates and their respective officers, directors, agents,

                   PARTY ") to the fullest extent permitted by law from and
                   against any and all Losses resulting from, arising out of or

                   8.2 to any Priceline Indemnified Party to the extent that it
                   is finally judicially determined that such Losses resulted
                   primarily from the material breach by any Priceline
                   Indemnified Party of any representation, warranty, covenant
                   or agreement of such Priceline Indemnified Party contained in
                   the Transaction Documents, and PROVIDED, FURTHER, that if and
                   to the extent that such indemnification is unenforceable for
                   any reason, Delta shall make the maximum contribution to the
                   payment and satisfaction of such Losses which shall be
                   permissible under applicable laws.

         8.3       Except as otherwise provided in this Article 8, Priceline
                   agrees to indemnify, defend and hold harmless Delta and its
                   affiliates and their respective officers, directors, agents,
                   employees, and subsidiaries (each, a "DELTA INDEMNIFIED

                   that such indemnification is unenforceable for any reason,
                   Priceline shall make the maximum contribution to the payment
                   and satisfaction of such Losses which shall be permissible
                   under applicable laws.

         8.4       Each Priceline Indemnified Party or Delta Indemnified Party,
                   as the case may be (for purposes of this Section 8.4, an
                   "INDEMNIFIED PARTY"), under this Section 8 shall, promptly
                   after the receipt of notice of the commencement of any
                   action, investigation, claim or other proceeding against such
                   Indemnified Party in respect of which indemnity may be sought
                   from Delta or Priceline (for purposes of this Section 8.4, an
                   "INDEMNIFYING PARTY") under this Section 8, notify the
                   Indemnifying Party in writing of the commencement thereof.
                   The omission of any Indemnified Party so to notify the
                   Indemnifying Party of any such action shall not relieve the
                   Indemnifying Party from any liability which it may have to
                   such Indemnified Party unless, and only to the extent that,
                   such Indemnifying Party has been prejudiced thereby. In case
                   any such action, claim or other proceeding shall be brought
                   against any Indemnified Party, and it shall notify the
                   Indemnifying Party of the commencement thereof, the
                   Indemnifying Party shall be entitled to assume the defense
                   thereof at its own expense, with counsel satisfactory to such
                   Indemnified Party in its reasonable judgment; PROVIDED,
                   HOWEVER, that any Indemnified Party may, at its own expense,
                   retain separate counsel to participate in such defense at its
                   own expense. Notwithstanding the foregoing, in any action,
                   claim or proceeding in which both the Indemnifying Party, on
                   the one hand, and an Indemnified Party, on the other hand,
                   are, or are reasonably likely to become, a party, such
                   Indemnified Party shall have the right to employ separate
                   counsel at the expense of the Indemnifying Party and to
                   control its own defense of such action, claim or proceeding
                   if, in the reasonable opinion of counsel to such Indemnified
                   Party, a

                   conflict or potential conflict exists between the
                   Indemnifying Party, on the one hand, and such Indemnified
                   Party, on the other hand, that would make such separate
                   representation advisable; PROVIDED, HOWEVER, that the
                   Indemnifying Party shall not be liable for the fees and
                   expenses of more than one counsel to all Indemnified Parties.
                   The Indemnifying Party agrees that it will not, without the
                   prior written consent of the Indemnified Party, settle,
                   compromise or consent to the entry of any judgment in any
                   pending or threatened claim, action or proceeding relating to
                   the matters contemplated hereby (if any Indemnified Party is
                   a party thereto or has been actually threatened to be made a
                   party thereto) unless such settlement, compromise or consent
                   includes an unconditional release of the Indemnified Party
                   from all liability arising or that may arise out of such
                   claim, action or proceeding. The Indemnifying Party shall not
                   be liable for any settlement of any claim, action or
                   proceeding effected against an Indemnified Party without the
                   Indemnifying Party's written consent, which consent shall not
                   be unreasonably withheld.

9.       REGISTRATION RIGHTS AGREEMENT

         enter into a Registration Rights Agreement in the form of the

         Priceline Inc., General Atlantic Partners 48 L.P., GAP Coinvestment
         Partners, L.P. and certain stockholders named therein.

10.      GENERAL PROVISIONS

         10.1      No waiver or breach of any of the provisions of this
                   Agreement shall be construed as a waiver of any succeeding
                   breach of the same or any other provision.

         10.2      If any paragraph, sentence or clause of this Agreement shall
                   be adjudged illegal, invalid or unenforceable, such
                   illegality, invalidity or unenforceability shall not affect
                   the legality, validity or enforceability of this Agreement as
                   a whole or of any paragraph, sentence or clause hereof not so
                   adjudged.

         10.4      This Agreement and the Attachments hereto supersede and
                   replace all previous understandings or agreements, whether
                   oral or written, with respect to the subject matter hereof.

                   amendment executed by the parties.

         10.6      The formation, construction, performance and validity of this
                   Agreement shall be governed by the internal laws of the

                   obligations under this Agreement may be brought against it
                   either in the state or federal courts of the principal place
                   of business of either party, and each party hereby
                   irrevocably submits to the jurisdiction of such courts and
                   irrevocably waives, to the fullest extent permitted by law,
                   any objections that it may now or hereafter have to the
                   laying of the venue of such civil suit or action and any
                   claim that such civil suit or action has been brought in an
                   inconvenient forum, and each party further agrees that final
                   judgment in any such civil suit or action shall be conclusive
                   and binding upon it and shall be enforceable against it by

                   jurisdiction.

         10.9      Priceline agrees to notify Delta promptly, in writing, in the
                   event there is a change of control in the ownership of
                   PriceLine Inc. For purposes of this Agreement, a "change of
                   control" with respect to a party means (i) the acquisition by
                   any other person or group (within the meaning of Section
                   13(d)(3) of the Securities Exchange Act (except an employee
                   group of such party, any of its subsidiaries or a holding
                   company of such party)), of the beneficial ownership of
                   securities representing 20% or more of the combined voting
                   power of the securities entitled to vote generally in the
                   election of the board of directors of such party, or (ii) the
                   sale, mortgage, lease or other transfer of assets or earning
                   power constituting more than 50% of the assets or earning
                   power of such party (other than ordinary course financing);
                   provided that in no event shall a "change of control be
                   defined to include (i) an initial public offering of shares
                   of a party's capital stock, (ii) the formation by a party of
                   a holding company, or (iii) an intra-corporate transaction
                   with a company under common control with a party.

         10.11     No party hereto shall assign or transfer or permit the
                   assignment or transfer of this Agreement without the prior
                   written consent of the other parties.

         10.12     This Agreement shall not be deemed to create any partnership
                   or joint venture between Delta and Priceline, nor to create
                   any rights in favor of any person or entity other than the
                   parties hereto. This Agreement is for the sole benefit of the
                   parties and nothing herein expressed or implied shall give or
                   be construed to give any other person any legal or equitable
                   rights hereunder.

         10.13     NO PARTY WILL BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL
                   DAMAGES, INCLUDING LOST REVENUES, LOST PROFITS, OR LOST
                   PROSPECTIVE ECONOMIC ADVANTAGE, ARISING FROM THIS AGREEMENT
                   OR ANY BREACH HEREOF.

         10.14     THE PARTIES AGREE THAT IRREPARABLE DAMAGE WOULD OCCUR IN THE
                   EVENT ANY PROVISION OF THIS AGREEMENT IS NOT PERFORMED IN
                   ACCORDANCE WITH THE TERMS HEREOF AND THAT THE PARTIES SHALL

                   ENTITLED TO AN INJUNCTION OR INJUNCTIONS TO PREVENT
                   BREACHES OF THIS AGREEMENT AND TO ENFORCE
                   SPECIFICALLY THE TERMS AND PROVISIONS OF THIS
                   AGREEMENT.

         10.15     Each party has participated jointly in the negotiation and
                   drafting of this Agreement. In the event any ambiguity or
                   question of intent or interpretation arises, this Agreement
                   shall be construed as if drafted jointly by the parties, and
                   no presumption or burden of proof shall arise favoring or
                   disfavoring any party by virtue of the authorship of any of
                   the provisions of this Agreement.

         10.16     In the event that either party hereto is prevented from
                   fulfilling any of its obligations under this Agreement for a
                   period not exceeding one hundred twenty (120) consecutive
                   days for a reason beyond its control, including, but not
                   limited to, strikes, lockouts, work stoppages or other labor
                   disputes, riots, civil commotions, acts of God, fire, flood
                   and other weather-related reasons, governmental action or
                   directive (a "FORCE MAJEUR EVENT"), such party shall not, by
                   reason of being so prevented, be in breach of this Agreement
                   and such condition shall not be cause of termination by the
                   other party. If a Force Majeur Event continues for a period
                   in excess of one hundred twenty (120) consecutive days as to
                   one party which prevents that party from fulfilling in any
                   material way its obligations under this Agreement to the
                   other party, the other party shall have the right to
                   terminate this Agreement upon thirty (30) days' advance
                   written notice to the other party.

                         AIRLINE PARTICIPATION AGREEMENT

         THIS AGREEMENT (this "Agreement"), dated August 31, 1998, is by and
among priceline.com Incorporated, a Delaware corporation with an address at Five
High Ridge Park, Stamford, Connecticut 06905 ("PRICELINE INC."), PriceLine
Travel, Inc., a Delaware corporation with an address at 5 High Ridge Park,
Stamford, Connecticut 06905 ("PriceLine Travel" and, together with Priceline
Inc., being collectively referred to herein as "PRICELINE"), and the undersigned
airline, whose principal place of business is set forth on the signature page of
this agreement ("Airline").

                             PRELIMINARY STATEMENT:

         Priceline provides a service that allows consumers to purchase airline
tickets at an offer price determined by the consumer (the "PRICELINE SERVICE").
The consumer identifies the departure and return dates for travel and the price
the consumer is willing to pay for the airline ticket(s). Priceline then
determines if it is able to fulfill the customer's offer and, if it is able to
do so, PriceLine Travel issues a ticket to the customer on the applicable
carrier.

         Airline desires to participate in the Priceline Service and, in
connection therewith, will provide Priceline with unpublished fares subject to
the Restrictions (defined herein) for select origin and destination city pairs
(each, an "O&D") identified by Airline in accordance with the terms and
conditions set forth in this Agreement.

         Priceline desires to include Airline as a participating carrier in the
Priceline Service and to have access to such unpublished fares in accordance
with the terms and conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the covenants and agreements set
forth in this Agreement, the parties agree as follows:

I.       TICKET RESTRICTIONS AND RELATED MATTERS

         1.       Airline shall make available unpublished fares to Priceline
                  for O&Ds identified by Airline in accordance with the terms
                  and conditions set forth in this Agreement. Unpublished fares
                  provided to Priceline must be issued in accordance with rules
                  and restrictions provided to Priceline from time to time. By
                  way of example, unpublished fares on certain O&D's may require
                  specific routings or be flight/day specific. At all times
                  during the term of this Agreement, Airline will control and
                  determine the unpublished fares and levels of inventory
                  provided to Priceline. It is expressly understood and agreed
                  that Airline makes no commitment whatsoever regarding the
                  level of inventory, number of O&Ds or the level of unpublished
                  fares that will be provided to Priceline.

         2.       All tickets issued by Priceline for carriage on Airline (each,
                  a "PRICELINE TICKET") shall be subject to the following
                  restrictions (the "RESTRICTIONS"):

                  (a)      All Priceline Tickets will be non-refundable,
                           non-endorsable and non- changeable;
                  (b)      All travel will be round-trip with no stopovers or
                           open-jaw travel permitted;
                  (c)      Frequent Flyer mileage and upgrades will not be
                           permitted; provided, Airline may offer such benefits
                           to the extent that it is impractical to impose
                           frequent flyer restrictions on Priceline Tickets;
                  (d)      Priceline customers must agree to (i) make at least
                           one stop or connection on both their departing and
                           return flights, (ii) accept a ticket on any
                           Participating Carrier, and (iii) travel on any flight
                           on the specified date of travel (x) for domestic U.
                           S. flights, during the 6 a.m. - 10 p.m. time period
                           [unless the customer has specified a request to
                           include flights departing outside those periods], and
                           (y) for international flights, at any time (i.e.,
                           12:01 a.m. to 11:59 p.m.);
                  (e)      All Priceline travel reservations and bookings shall
                           be made without Priceline customers specifying a
                           preferred (or

                           preference(s) on the specified date(s) of travel;
                  (f)      All Priceline Tickets require instant ticketing
                           guaranteed with a major credit card if Priceline is
                           able to provide an airline ticket within the
                           customer's requested price, departure and return date
                           parameters; and
                  (g)      Priceline Ticket reservations are limited to no more
                           than eight persons traveling in the same itinerary.
                  (h)      In any seven day calendar period, a Priceline
                           customer shall be limited to making one offer price
                           for airline ticket(s) for a Trip. A "TRIP" is defined
                           as travel between the same airports on the same dates
                           of travel. A Priceline customer may, within a seven
                           calendar day period, make an offer for travel in a
                           different airport pair or on different dates of
                           travel. Priceline will not sell a ticket to a
                           Priceline customer in response to a second (or
                           subsequent) offer for a Trip within a seven calendar
                           day period; provided, that Priceline may sell a
                           ticket in connection with a second offer if the
                           Priceline customer (i) raises the offer by a minimum
                           of [**] and (ii) accepts, as part of the second
                           offer, (x) a travel package which includes a hotel or
                           rental car offer, or (y) a product or service
                           co-marketed by Priceline such as a credit card or
                           long distance telephone service; provided further,
                           that Priceline shall limit the number of such second
                           offers to not greater than twenty percent (20%) of
                           first offers.

         3.       Airline may include, in addition to the Restrictions, other
                  fare rules and conditions for Priceline Tickets issued on
                  Airline such as advance purchase or Saturday night stay
                  requirements. Priceline also reserves the right to impose
                  additional restrictions on Priceline Tickets, including a
                  Saturday night stay requirement, as part of the Restrictions.

         4.       The Restrictions will apply to all tickets issued through the
                  Priceline Service on Airline. Airline may waive, at its own
                  cost and expense, one or more of the Restrictions pursuant to
                  a direct arrangement made by Airline with the applicable
                  customer holding a Priceline Ticket. On an exception basis
                  where necessary or appropriate to promote customer good will,
                  Priceline may refund the price of a Priceline


[**] = Confidential treatment requested for redacted portion.



                                        3

<PAGE>



                  Ticket pursuant to a direct arrangement made by Priceline with
                  the applicable customer. Priceline shall provide Airline with
                  a monthly report detailing the number and amount of refunded
                  Priceline Tickets involving air transportation services on
                  Airline.

         5.       The Restrictions will be communicated by Priceline to the
                  customer via the Internet (or through Priceline's customer
                  service representatives if the consumer contacts Priceline
                  through its toll free customer service number), and will be
                  set forth on ticketing and/or itinerary documentation issued
                  by PriceLine Travel.

         6.       All Priceline Tickets issued for carriage on Airline shall be
                  subject to the published conditions of carriage and the fare
                  rules of Airline, to the extent such conditions and fare rules
                  are consistent with the Restrictions. Airline will honor all
                  Priceline Tickets issued for travel on Airline in accordance
                  with the Restrictions and other rules and conditions
                  established by Airline for Priceline Tickets.

II.      PRICELINE TICKET RESERVATIONS, BOOKINGS, PAYMENT AND FULFILLMENT

         1.       Airline will file unpublished fares and rules for Priceline
                  Tickets with the computer reservation system ("CRS") used by
                  Priceline Travel.

         2.       Priceline will determine the price at which tickets are sold
                  based on customer offers received through the Priceline
                  Service. Priceline shall not advertise prices or fares below
                  Airline's published fares. As used herein, "published fare"
                  means an Airline fare published through the Airline Tariff
                  Publishing Company (ATP) and available for sale by Airline
                  appointed agents for scheduled air transportation.

         3.       All unpublished fares made available by Airline for sale
                  through the Priceline Service shall not be commissionable and
                  shall be inclusive of the domestic 9% federal transportation
                  excise tax. All such unpublished fares shall be exclusive of
                  any domestic federal segment taxes, and any domestic or
                  international fuel, departure, arrival, passenger facility,
                  airport, terminal and/or security taxes or surcharges which,
                  when applicable, must be added to the fare amount collected
                  from the passenger and shown on the Priceline Ticket.

                                        4

<PAGE>




         4.       Upon locating a unpublished fare satisfying a Priceline
                  customer's ticket request, PriceLine Travel shall immediately
                  ticket the customer's ticket price against a valid credit card
                  provided by the Priceline customer.

         5.       In all Priceline Ticket transactions, PriceLine Travel will be
                  the merchant of record and will pay all associated merchant
                  credit card fees. All Priceline tickets sold on Airline will
                  be settled through ARC.

         6.       All tickets of Airline issued through the Priceline Service
                  will be issued by PriceLine Travel using Agency ARC:
                  07-50854-6. In collecting payment for Priceline Tickets,
                  PriceLine Travel will act as the agent of Airline pursuant to
                  Agent's ARC Agent Reporting Agreement with the Airlines
                  Reporting Corporation ("ARC").

         7.       Unless otherwise directed by a Priceline customer, all
                  Priceline Tickets issued on Airline will be issued
                  electronically. After issuance, Priceline will promptly
                  forward to the customer a receipt of proof of purchase,
                  contract of carriage on Airline and a copy of the Restrictions
                  (including any additional restrictions imposed by Airline). In
                  the event a Priceline customer requests Airline to provide a
                  separate electronic ticket receipt for an electronic ticket
                  issued by PriceLine Travel, Priceline agrees that the price
                  shown on Airline's receipt will reflect the unpublished fare
                  to PriceLine Travel until such time as Airline is reasonably
                  able to produce "bulk" electronic tickets. Insofar as the
                  disclosure of unpublished net fare information to the customer
                  may create customer relations issues for Airline, Airline may
                  direct PriceLine Travel to issue paper tickets until such time
                  as Airline is reasonably able to produce "bulk" electronic
                  tickets. To the extent the disclosure of such unpublished fare
                  information to the Priceline customer creates ongoing customer
                  relations issues for Priceline, PriceLine Travel may, upon
                  reasonable notice to Airline, independently issue paper
                  tickets to customers purchasing tickets on Airline until such
                  time as Airline produces "bulk" electronic tickets.

         8.       Subject to the provisions of Paragraph II.7 above, Priceline
                  will encourage its customers to accept electronic ticketing
                  for all PriceLine Ticket requests by imposing an additional
                  charge for the issuance of paper tickets and maintaining the
                  issuance of electronic tickets as the default option on the
                  Priceline Service.

         9.       Subject to the provisions of Paragraph II.5 above, all
                  Priceline paper tickets for carriage on Airline will be issued
                  by PriceLine Travel on standard ARC traffic documents and will
                  be validated with Airline's validation in accordance with ARC
                  requirements. The passenger coupon will show "bulk" for the
                  fare amount and will include all additional collections noted
                  in Paragraph II.3 above. The auditor's coupon will show the
                  Airline's unpublished fare as authorized by PriceLine Travel.

         10.      In the event that Priceline is unable to fulfill a Priceline
                  ticket request from unpublished fares and seat inventory
                  provided from airlines participating in the Priceline Service,
                  Priceline reserves the right to sell tickets on Airline using
                  published fares used by travel agents generally as reflected
                  in CRSs, in accordance with the rules and conditions
                  associated with such fares.

         11.      At the request of Airline, Priceline will incorporate into the
                  Priceline Service a "hot link" to the designated Internet site
                  of Airline; PROVIDED, HOWEVER, that Priceline will have a
                  reasonable period of time following any such request to
                  accomplish any system changes, additions or enhancements
                  necessary or appropriate for the inclusion of any such "hot
                  link."

III.     PRICELINE TICKET ALLOCATION METHODOLOGY

                  All airlines participating in the Priceline Service will be
                  given the first opportunity to fill a customer ticket request
                  based on a formula [**]. If a participating airline fails to
                  respond to a ticket request on its designated first look, then
                  Priceline will allocate the request through a second round of
                  preferred looks, [**] for each O&D requested (but excluding
                  the participating airline that failed to fulfill the ticket
                  request on the first look).

IV.      PRICELINE CUSTOMER SERVICE; JOINT MARKETING

         1.       Priceline will provide twenty-four hour customer support
                  services to all Priceline customers through a toll-free number
                  at the customer support center designated by Priceline from
                  time to time. The customer support center will be adequately
                  staffed with personnel trained to take Priceline Ticket
                  requests by phone and respond to all customer inquiries for
                  related service and support.

         2.       Priceline will use commercially reasonable efforts to ensure
                  that its customer service representatives provide quality
                  customer service and support to Priceline customers in a
                  prompt, reliable and courteous manner.

         3.       Priceline will respond to Priceline customer questions and
                  issues pertaining to special handling requirements for
                  Priceline Tickets including processing any special customer
                  handling requirements in respect of Priceline Tickets issued
                  on Airline.

V.       CONFIDENTIALITY

         1.       Priceline and Airline will each hold in confidence and,
                  without the prior written consent of the other, will not
                  reproduce, distribute, transmit, transfer or disclose directly
                  or indirectly, in any form, by any means or for any purpose,
                  any Confidential Information of the other party. As used
                  herein, the term "CONFIDENTIAL INFORMATION" shall mean this
                  Agreement and its subject matter, and proprietary information
                  that is provided to or obtained from one party to the other
                  party including any information which derives economic value,
                  actual or potential, from not being generally known to, and
                  not generally ascertainable by proper means by, other persons,
                  including the unpublished fares provided by Airline to
                  Priceline pursuant to this Agreement. The recipient of
                  Confidential Information may only disclose such information to
                  its employees on a need-to-know basis.

         2.       The obligations of a recipient party with respect to
                  Confidential Information shall remain in effect during and
                  after the term of this

                  Agreement (including any renewals or extensions hereof) and
                  for a period of five (5) years thereafter, except to the
                  extent such data:

                  (a)      is or becomes generally available to the public other
                           than as a result of a disclosure by the recipient, or
                           its directors, officers, employees, agents or
                           advisor;

                  (b)      becomes available to the recipient on a
                           non-confidential basis from a source other than the
                           disclosing party or its affiliated companies,
                           provided that such source is not bound by any
                           confidentiality obligations to the disclosing party
                           or its affiliated companies (as applicable); or

                  (c)      is necessary to comply with applicable law or the
                           order or other legal process of any court,
                           governmental or similar authority having jurisdiction
                           over the recipient.

         3.       In the event that the recipient becomes legally compelled to
                  disclose any of such Confidential Information by any
                  governmental body or court, recipient will provide the
                  disclosing party with prompt notice so that the disclosing
                  party may seek a protective order or other appropriate remedy
                  and/or waive compliance (in writing) with the provisions
                  hereof. In the event that such protective order or other
                  remedy is not obtained, or the disclosing party waives (in
                  writing) compliance with the provisions hereof, recipient will
                  furnish only that portion of such Confidential Material which
                  is legally required and will exercise its reasonable business
                  efforts to obtain appropriate assurance that confidential
                  treatment will be accorded such Confidential Information.

         4.       The recipient of Confidential Information will exercise
                  reasonable commercial care in protecting the confidentiality
                  of the other party's Confidential Information.

         5.       Priceline will not disclose (including, without limitation, by
                  sale) to any third party information obtained through the
                  Priceline Service concerning a customer who has acquired a
                  ticket on Airline using the Priceline Service.

         6.       Priceline will not identify Airline's participation in the
                  Priceline Service until a customer is booked and confirmed for
                  ticketing. Further, Priceline will not, in any media
                  (including its Internet site), indicate that Airline is
                  participating or has participated in the Priceline Service
                  except to indicate that as a consumer proposition, a Priceline
                  customer must accept a routing on one of the major U.S. full
                  service airlines or, in the case of international travel,
                  other airline carriers available through the Priceline
                  Service. Except as set forth above, Priceline will not
                  disclose Airline's participation in the Priceline Service
                  without Airline's prior consent. Airline will not disclose its
                  participation in the Priceline Service without Priceline
                  Inc.'s prior consent.

VI.      PROPRIETARY MARKS

                  During the term of this Agreement neither Priceline nor
                  Airline shall use the other party's trademarks, trade names,
                  service marks, logos, emblems, symbols or other brand
                  identifiers in advertising or marketing materials, unless it
                  has obtained the prior written approval of the other party.
                  The consent required by this Paragraph VI shall extend to the
                  content of the specific advertising or marketing items as well
                  as the placement and prominence of the applicable trademark,
                  trade name, service mark, logo, emblem, symbol or other brand
                  identifier of the other party. Priceline or Airline, as
                  applicable, shall cause the withholding, discontinuance,
                  recall or cancellation, as appropriate, of any advertising or
                  promotional material not approved in writing by the other
                  party, that differs significantly from that approved by the
                  other party, or that is put to a use or used in a media not
                  approved by the other party.

VII.     REPORTING; AUDIT RIGHTS

         1.       Priceline will provide monthly reports in a format designated

                  information (i.e. non airline specific) for all tickets issued

                  participates.

         2.       Priceline will provide to Airline an annual statement by
                  Priceline's independent accounting firm or other qualified

                  Priceline Ticket Allocation Methodology specified in Section
                  III and all reporting obligations
                  required by this Agreement.

         3.       Airline may, upon reasonable notice to Priceline and during
                  normal business hours, audit the financial books and records
                  of Priceline and the information specified in Sections VII.I
                  and 2. Any such audit shall be at the sole cost and expense of
                  Airline and shall be conducted in a manner that does not
                  unduly disrupt or interfere with the normal business
                  operations of Priceline.

VIII.    TERM OF AGREEMENT

                  may terminate this Agreement at any time after the
                  Commencement Date in the event of a change of control of
                  Priceline Inc., other than a change of control resulting from
                  an initial public offering of shares of Priceline Inc. capital
                  stock.

         2.       Any party may terminate this Agreement at any time after the
                  Commencement Date if another party is in material breach of
                  its obligations hereunder and has failed to fully cure such
                  breach within thirty (30) days following its receipt of notice

                  be adjudged illegal, invalid or unenforceable, such
                  illegality, invalidity or unenforceability shall not affect

                  recipient of copies of notices for purposes of this Agreement

                  recipient in accordance with this Paragraph XI(3).

         4.       This Agreement and the Attachments hereto supersede and
                  replace all previous understandings or agreements, whether
                  oral or written, with respect to the subject matter hereof .
                  The captions in this Agreement are for convenience only and do

         5.       This Agreement may be amended or modified only by a written

         6.       The formation, construction, performance and validity of this
                  Agreement shall be governed by the internal laws of the State
                  of New York. Each party agrees that any civil suit or action
                  brought against it as a result of any of its obligations under
                  this Agreement may be brought against it either in the state

                  enforceable against it by suit upon such judgment in any court
                  of competent jurisdiction.

         7.       This Agreement may be executed in counterparts, each of which
                  shall be deemed an original, and together, shall constitute

         8.       No party will in any manner or by any device, either directly
                  or indirectly, act in violation of any applicable law,
                  governmental order or regulation. PriceLine Travel shall
                  comply at all times with the provisions of Airline's tariffs
                  (except where such tariffs are specifically amended by Airline
                  under the terms of this Agreement) and the terms of the
                  Airlines Reporting Corporation (ARC) Agent Reporting Agreement
                  and any addenda thereto.

         9.       Priceline agrees to notify Airline promptly, in writing, in
                  the event there is a change of control in the ownership of
                  PriceLine Inc. For purposes of this Agreement, a " change of
                  control" with respect to a party means (i) the acquisition by
                  any other person or group (within the meaning of Section
                  13(d)(3) of the Securities Exchange Act (except an employee
                  group of such party, any of its subsidiaries or a holding
                  company of such party)), of the beneficial ownership of
                  securities representing 20% or more of the combined voting
                  power of the securities entitled to vote generally in the
                  election of the board of directors of such party, or (ii) the
                  sale, mortgage, lease or other transfer of assets or earning
                  power constituting more than 50% of the assets or earning
                  power of such party (other than ordinary course financing);
                  PROVIDED that in no event shall a "change of control be
                  defined to include (i) an initial public offering of shares of
                  a party's capital stock, (ii) the formation by a party of a
                  holding company, or (iii) an intra-corporate transaction with
                  a company under common control with a party.

         10.      No party hereto shall assign or transfer or permit the
                  assignment or transfer of this Agreement without the prior
                  written consent of the other parties.

         11.      This Agreement shall not be deemed to create any partnership
                  or joint venture between Airline and Priceline, nor to create
                  any rights in favor of any person or entity other than the
                  parties hereto. This Agreement is for the sole benefit of the
                  parties and nothing herein expressed or implied shall give or

         12.      NO PARTY WILL BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL
                  DAMAGES, INCLUDING LOST REVENUES, LOST PROFITS, OR LOST
                  PROSPECTIVE ECONOMIC ADVANTAGE, ARISING FROM THIS AGREEMENT OR
                  ANY BREACH HEREOF.

         13.      THE PARTIES AGREE THAT IRREPARABLE DAMAGE WOULD OCCUR IN THE
                  EVENT ANY PROVISION OF THIS AGREEMENT IS NOT PERFORMED IN
                  ACCORDANCE WITH THE TERMS HEREOF AND THAT THE PARTIES SHALL BE
                  ENTITLED TO AN INJUNCTION OR INJUNCTIONS TO PREVENT BREACHES
                  OF THIS AGREEMENT AND TO ENFORCE SPECIFICALLY THE TERMS AND
                  PROVISIONS OF THIS AGREEMENT.

         14.      Each party has participated jointly in the negotiation and
                  drafting of this Agreement. In the event any ambiguity or
                  question of intent or interpretation arises, this Agreement
                  shall be construed as if drafted jointly by the parties, and
                  no presumption or burden of proof shall arise favoring or
                  disfavoring any party by virtue of the authorship of any of
                  the provisions of this Agreement

         15.      In the event that either party hereto is prevented from
                  fulfilling any of its obligations under this Agreement for a
                  period not exceeding one hundred twenty (120) consecutive days
                  for a reason beyond its control, including, but not limited
                  to, strikes, lockouts, work stoppages or other labor disputes,
                  riots, civil commotions, acts of God, fire, flood and other
                  weather-related reasons, governmental action or directive (a
                  "FORCE MAJEUR EVENT"), such party shall not, by reason of
                  being so prevented, be in breach of this Agreement and such
                  condition shall not be cause of termination by the other
                  party. If a Force Majeur Event continues for a period in
                  excess of one hundred twenty (120) consecutive days as to one
                  party which prevents that party from fulfilling in any
                  material way its obligations under this Agreement to the other
                  party, the other party shall have the right to terminate this
                  Agreement upon thirty (30) days' advance written notice to the
                  other party.

   AMENDMENT TO THE AIRLINE PARTICIPATION AGREEMENT AND THE GENERAL AGREEMENT



December 31, 1998


Ms. Brenda Barnes
Vice President,
   Pricing & Revenue Management
Delta Air Lines, Inc.
1030 Delta Boulevard
Hartsfield Atlanta International Airport
Atlanta, GA 30320

Dear Brenda:

The following provisions shall be deemed an amendment to the Airline
Participation Agreement and the General Agreement between and among Delta Air
Lines, Inc. ("Delta") and priceline.com Incorporated and PriceLine Travel, Inc.
(collectively, as applicable, "Priceline"), where indicated, in each case,
effective as of December 31, 1998. Unless otherwise defined herein, capitalized
terms shall have the meanings set forth in the Airline Participation Agreement
and the General Agreement, as applicable.

1.   The following provision replaces Section 7.11 of the General Agreement in
     its entirety:

     7.11   PRICELINE TICKET ALLOCATION METHODOLOGY

            (a) All airlines participating in the Priceline Service will be
            given the first opportunity to fill a customer ticket request based
            on a formula [**] except for offers originating or terminating in
            the following markets where the [**] rule will not apply: [**] 
            The operation of this first look methodology is reflected in the 
            example attached hereto as Exhibit 7.11, and incorporated by 
            reference herein.

            (b) Priceline shall, within 60 days of the implementation of the
            allocation system described in Section 7.11 (a) (which is scheduled
            for completion at the end of February), and thereafter as requested
            by Delta, [**] will apply to all O&D markets including, without
            limitation, the top 2,500 domestic O&D markets and the top 1,000
            international O&D markets.

[**] = Confidential treatment requested for redacted portion.


<PAGE>
            (c) The first opportunity to fill a customer ticket request [**] in
            the event Delta's market share (as measured in RPMs) increases
            versus the rest of the Participating Carriers [**].

            (d) Until technology is developed to implement the proposed first
            look allocation method discussed above [**].

            (e) Section 7.11 (a)-(d) as set forth above shall no longer be in
            effect if Delta's rights under Section 3.1-3.4 of the General
            Agreement are terminated pursuant to Section 3.5 of the General
            Agreement. In such event, the following provision shall be
            substituted for Section 7.11 of the General Agreement:

                 7.11 All Participating Carriers will be given the first
                 opportunity to fill a customer ticket request based on a
                 formula [**]. If a Participating Carrier fails to respond to a
                 ticket request on its designated first look, then Priceline
                 will allocate the request through a second round of preferred
                 looks [**] for each O&D requested (but excluding the
                 Participating Carrier that failed to fulfill the ticket request
                 on the first look).

2.   The following provision is added as a new section 7.14 of the General
     Agreement:

     7.14   DETERMINATION OF REASONABLE DEMAND

            Beginning at the end of February of 1999, and thereafter on a
            mutually agreed schedule, Priceline will review with Delta the
            methodology used by Priceline to establish reasonable demand that
            Priceline elects to process for both domestic and international O&D
            offers.

3.   The following provision replaces Section 3.1 of the General Agreement in
     its entirety:

     3.1    Subject to Section 3.5 below, Delta and Priceline agree that, during
            the term of the PCA:

            (a) (i) all airlines which have signed an agreement with Priceline
            to participate in the Priceline Service as of the date of the
            Agreement (as identified in the attached Schedule 3.1 hereof) may
            continue such participation; (ii) Delta consents to participation by
            the following airlines: [**] or such other U.S. domestic airline(s)
            which are acceptable to Delta (as reflected by Delta's consent) with
            a goal of including in the Priceline Service a total number of
            domestic airline participants so that the sum total domestic market
            share of all such participating airlines will, in an annual
            measuring period, not exceed [**] of all U.S. domestic RPMs (the
            "Range"); (iii) the following carriers will constitute "Delta
            Connection Carriers": [**]; and "Delta Connection Carriers" may file
            Priceline fares (x) under the "DL" code and (y) to/from markets in
            their local O&D's not served by Delta; (iv) Priceline may include
            [**] as a participant subject to the restrictions set forth in
            Section 3.1 (b) below; (v) Priceline may add the following carriers
            on international markets: (x) [**] (the "Atlantic Excellence
            Partners") (y)[**] (the "Delta Partners") and

[**] = Confidential treatment requested for redacted portion.

                                        2

<PAGE>

            (z)[**] (the carriers referred to in subsections (x), (y) and (z)
            being collectively referred to as the "New International Carriers");
            and (vi) such other international carriers as Delta shall approve in
            writing, provided that Delta agrees to negotiate in good faith with
            respect to the addition of international carriers serving markets in
            which Priceline's rate of satisfying reasonable offers ("bind rate")
            is materially below Priceline's international average bind rate as
            measured over a period of not less than a calendar quarter.

            (b) Priceline agrees that it will not issue tickets (i) on [**] in
            the following markets: (x) to or from ATL, BOS, DFW, CVG and SLC
            (the "Delta Key Markets"), except for offers originating from MSP,
            DTW and MEM or O&D markets not served by Delta or a carrier
            operating a flight under Delta's two letter ("DL") designator code
            and (y) to, from or in the State of Florida, except for flights from
            MSP, DTW or MEM or O&D markets not served by Delta or a carrier
            operating a flight under Delta's two letter ("DL") designator code;
            (ii) on any carrier operating a flight under [**] two letter
            designator code flights except for [**] commuter carriers; or (iii)
            on the New International Carriers in the Delta Key Markets except
            (x) in markets not served by Delta (either directly or on a
            code-share basis), or (y) in markets where Priceline's rate of
            satisfying reasonable offers ("bind rate") is materially below
            Priceline's international average bind rate as measured over a
            period not less than one calendar quarter.

            (c) Priceline will continue to use its best efforts to pursue the
            participation of [**] in the Priceline Service.

            (d) Priceline agrees that for tickets sold by its international 
            Participating Carriers (i) it will only issue tickets for 
            international travel on flights operated by its international 
            Participating Carriers and not on flights marketed by its 
            international Participating Carriers but operated by other 
            carriers except for (x) grandfathered participants under their 
            current partner agreements listed in Schedule 3.1, (y) [**] code 
            share partners under its current participation agreement (as 
            identified in Schedule 3.1 hereof), and (z) tickets issued on the 
            code share partners of international Participating Carriers 
            providing Priceline with net fares that are calculated off of 
            published fares that retain all of the published fare rules of 
            that fare; provided, however, that in the event that 
            international tickets sold through Priceline by international 
            Participating Carriers (excluding Delta) under the international 
            Participating Carriers' two letter designator code on flights 
            operated by other carriers exceed [**] of the total international 
            tickets sold through Priceline (excluding Delta) for a 
            consecutive 30-day period, Priceline will take action to reduce 
            this percentage below [**]; (ii) it will no issue tickets for 
            international travel on [**] originating from the Delta Key 
            Markets; and (iii) it will not issue tickets for international 
            travel on any of the "Atlantic Excellence Partners" or "Delta 
            Partners" if the airline in question ceases to participate in a 
            qualifying marketing program with Delta (as identified by Delta), 
            which will be effected by not extending the term of any 
            participation agreement with such a carrier once the term 
            expires, not to exceed one year from the time Delta provides 
            written notice to Priceline of such a cessation of participation. 
            In the event that Priceline is obligated to take action under 
            this Section 3.1 (d) to reduce the

[**] = Confidential treatment requested for redacted portion.


                                        3

<PAGE>

            percentage of tickets below [**], then Priceline shall use its
            reasonable best efforts to develop software programs to restrict
            this amount below the [**] threshold.

            (e) As to domestic travel, in the event that the percent of domestic
            tickets sold under the [**] code on flights operated by carriers
            other than [**] exceeds [**] of total Priceline sold domestic
            tickets for a consecutive 30-day period, Priceline will take action
            to reduce this percentage below [**] during any subsequent 30 day
            period of this Agreement. In the event that Priceline is obligated
            take action under this Section 3.1 (e) to reduce the percentage of
            tickets below [**], then Priceline shall use its reasonable best
            efforts to develop software programs to restrict this amount below
            the [**] threshold.

            (f) Delta may sell Priceline tickets under Delta's two letter
            designator code on flights operated by other carriers.

4.   The following provision replaces Article III of the Airline Participation
     Agreement in its entirety:

     III.   Priceline Ticket Allocation Methodology

            Priceline shall establish an allocation methodology that determines
            when participating airlines will be given the first opportunity to
            fill a customer ticket request, and may give preference to one or
            more participants in establishing such methodology. Priceline will
            work in good faith with each participating airline to assist such
            airline in achieving its objectives for the Priceline Service within
            the context of the allocation system.

5.   The following provision is added as a new Section 7.15 of the General
     Agreement.

     7.15   Priceline agrees to provide Delta the following weekly reports:

            a.   Total Delta revenue and tickets issued broken down by entity
                 (domestic and international);
            b.   Total Priceline tickets issued (in order to determine Delta's
                 ticketing share);
            c.   Total O&D's ticketed on Delta - broken down by market including
                 the following information: revenue, travel dates and length of
                 stay;
            d.   Total Priceline demand data - ranked by O&D; and
            e.   Bind rate information (i.e. number of tickets issued divided by
                 the number of offers)

6.   Except as provided herein, all other terms and conditions of the Airline
     Participation Agreement and the General Agreement shall remain in full
     force and effect. In the event any term or provision of the Airline
     Participation Agreement or the General Agreement is contrary to or
     inconsistent with this letter, the terms of this letter shall control.

If the above language is acceptable, please acknowledge your consent by signing
where indicated below and returning this letter to me for execution. In such
case, the terms set forth herein shall be deemed effective as of December 31,
1998.

referred to herein as "PRICELINE"), and the undersigned airline, whose principal
place of business is set forth on the signature page of this agreement
("Airline").

                             PRELIMINARY STATEMENT:

     Priceline provides a service that allows consumers to purchase airline
tickets at an offer price determined by the consumer (the "Priceline Service").
The consumer identifies the departure and return dates for travel and the price
the consumer is willing to pay for the airline ticket(s). Priceline then
determines if it is able to fulfill the customer's offer and, if it is able to
do so, PriceLine Travel issues a ticket to the customer on the applicable
carrier.

     Airline desires to participate in the Priceline Service and, in connection
therewith, will provide Priceline with unpublished fares subject to the
Restrictions (defined herein) for select origin and destination city pairs
(each, an "O&D") identified by Airline in accordance with the terms and
conditions set forth in this Agreement.

     Priceline desires to include Airline as a participating carrier in the
Priceline Service and to have access to such unpublished fares in accordance
with the terms and conditions set forth in this Agreement.

     NOW, THEREFORE, in consideration of the covenants and agreements set forth
in this Agreement, the parties agree as follows:

I.   TICKET RESTRICTIONS AND RELATED MATTERS

     1.     Airline shall make available unpublished fares to Priceline for O&Ds
            identified by Airline in accordance with the terms and conditions
            set forth in this Agreement. Unpublished fares provided to Priceline
            must be issued in accordance with rules

[**] = Confidential treatment requested for redacted portion.


<PAGE>

            and restrictions provided to Priceline from time to time. By way of
            example, unpublished fares on certain O&D's may require specific
            routings or be flight/day specific. At all times during the term of
            this Agreement, Airline will control and determine the unpublished
            fares and levels of inventory provided to Priceline. It is expressly
            understood and agreed that Airline makes no commitment whatsoever
            regarding the level of inventory, number of O&Ds or the level of
            unpublished fares that will be provided to Priceline.

     2.     All tickets issued by Priceline for carriage on Airline (each, a
            "PRICELINE TICKET") shall be subject to the following restrictions
            (the "RESTRICTIONS"):

            (a)  All Priceline Tickets will be non-refundable, non-endorsable
                 and non-changeable;

            (b)  All travel will be round-trip with no stopovers or open-jaw
                 travel permitted;

            (c)  Frequent Flyer mileage and upgrades will not be permitted;
                 provided, Airline may offer such benefits to the extent that it
                 is impractical to impose such frequent flyer restrictions on
                 Priceline Tickets;

            (d)  Priceline customers must agree to (i) make up to one stop or
                 connection on both their departing and return flights, (ii)
                 accept a ticket on any Participating Carrier, and (iii) travel
                 on any flight on the specified date of travel (x) for domestic
                 U.S. flights, departing during the 6 a.m. - 10 p.m. time period
                 [unless the customer has specified a request to include flights
                 departing outside those periods], and (y) for international
                 flights, at any time (i.e., 12:01 a.m. to 11:59 p.m.);

            (e)  All Priceline travel reservations and bookings shall be made
                 without Priceline customers specifying a preferred (or
                 requested) carrier, flight or time of day travel preference(s)
                 on the specified date(s) of travel;

            (f)  All Priceline Tickets require instant ticketing guaranteed with
                 a major credit card if Priceline is able to provide an airline
                 ticket within the customer's requested price, departure and
                 return date parameters;

            (g)  Priceline Ticket reservations are limited to no more than eight
                 persons traveling in the same itinerary; and

            (h)  In any seven-day calendar period, a Priceline customer shall be
                 limited to making one offer price for airline ticket(s) for a
                 Trip. A "Trip" is defined as travel between the same airports
                 on the same dates of travel. A Priceline customer may, within a
                 seven-calendar day period, make an offer for travel in a
                 different airport pair or on different dates of travel.
                 Priceline will not sell a ticket to a Priceline customer in
                 response to a second (or subsequent) offer for a Trip within a
                 seven calendar day period; provided, that Priceline may sell a
                 ticket in connection with a second offer if the

                                        2

<PAGE>

                 Priceline customer (i) raises the offer by a minimum of [**]
                 and (ii) accepts, as part of the second offer, (x) a travel
                 package which includes a hotel or rental car offer, or (y) a
                 product or service co-marketed by Priceline such as a credit
                 card or long distance telephone service; provided further, that
                 Priceline shall limit the number of such second offers to not
                 greater than twenty percent (20%) of first offers.

     3.     Airline may include, in addition to the Restrictions, other fare
            rules and conditions for Priceline Tickets issued on Airline such as
            advance purchase or Saturday night stay requirements. Priceline also
            reserves the right to impose additional restrictions on Priceline
            Tickets, including a Saturday night stay requirement, as part of the
            Restrictions.

     4.     The Restrictions will apply to all tickets issued through the
            Priceline Service on Airline. Airline may waive, at its own cost and
            expense, one or more of the Restrictions set forth in Sections I.2
            (a)-(f) pursuant to a direct arrangement made by Airline with the
            applicable customer holding a Priceline Ticket. On an exception
            basis where necessary or appropriate to promote customer good will,
            Priceline may refund the price of a Priceline Ticket pursuant to a
            direct arrangement made by Priceline with the applicable customer.
            Priceline shall provide Airline with a monthly report detailing the
            number and amount of refunded Priceline Tickets involving air
            transportation services on Airline.

     5.     The Restrictions will be communicated by Priceline to the customer
            via the Internet (or through Priceline's customer service
            representatives if the consumer contacts Priceline through its toll
            free customer service number), and will be set forth on ticketing
            and/or itinerary documentation issued by PriceLine Travel.

     6.     All Priceline Tickets issued for carriage on Airline shall be
            subject to the published conditions of carriage and the fare rules
            of Airline, to the extent such conditions and fare rules are
            consistent with the Restrictions. Airline will honor all Priceline
            Tickets issued for travel on Airline in accordance with the
            Restrictions and other rules and conditions established by Airline
            for Priceline Tickets.

II.  PRICELINE TICKET RESERVATIONS, BOOKINGS, PAYMENT AND FULFILLMENT

     1.     Airline will file unpublished fares and rules for Priceline Tickets
            with the computer reservation system ("CRS") used by Priceline
            Travel.


[**] = Confidential treatment requested for redacted portion.


                                        3

<PAGE>

     2.     Priceline will determine the price at which tickets are sold based
            on customer offers received through the Priceline Service. Priceline
            shall not advertise prices or fares below Airline's published or
            unpublished fares.

     3.     All unpublished fares made available by Airline for sale through the
            Priceline Service shall not be commissionable and shall be
            inclusive, where applicable, of the applicable domestic federal
            transportation excise tax. All such unpublished fares shall be
            exclusive of any domestic federal segment taxes, and any domestic or
            international fuel, departure, arrival, passenger facility, airport,
            terminal and/or security taxes or surcharges which, when applicable,
            must be added to the fare amount collected from the passenger and
            shown on the Priceline Ticket.

     4.     Upon locating an unpublished fare satisfying a Priceline customer's
            ticket request, PriceLine Travel shall immediately ticket the
            customer's ticket price against a valid credit card provided by the
            Priceline customer.

     5.     In all Priceline Ticket transactions, PriceLine Travel will be the
            merchant of record and will pay all associated merchant credit card
            fees. All Priceline tickets sold on Airline will be settled through
            ARC.

     6.     All tickets of Airline issued through the Priceline Service will be
            issued by PriceLine Travel using Agency ARC: 07-50854-6. In
            collecting payment for Priceline Tickets, PriceLine Travel will act
            as the agent of Airline pursuant to Agent's ARC Agent Reporting
            Agreement with the Airlines Reporting Corporation ("ARC").

     7.     Unless otherwise directed by a Priceline customer, all Priceline
            Tickets issued on Airline will be issued electronically. After
            issuance, Priceline will promptly forward to the customer a receipt
            of proof of purchase, contract of carriage on Airline and a copy of
            the Restrictions (including any additional restrictions imposed by
            Airline). In the event a Priceline customer requests Airline to
            provide a separate electronic ticket receipt for an electronic
            ticket, the price shown on Airline's receipt will reflect that such
            ticket is a "bulk" electronic ticket.

     8.     Priceline will encourage its customers to accept electronic
            ticketing for all PriceLine Ticket requests by imposing an
            additional charge for the issuance of paper tickets and maintaining
            the issuance of electronic tickets as the default option on the
            Priceline Service.

     9.     Subject to the provisions of Paragraph II.5 above, all Priceline
            paper tickets for carriage on Airline will be issued by PriceLine
            Travel on standard ARC traffic

[**] = Confidential treatment requested for redacted portion.


                                        4

<PAGE>

            documents and will be validated with Airline's validation in
            accordance with ARC requirements. The passenger coupon will show
            "bulk" for the fare amount and will include all additional
            collections noted in Paragraph II.3 above. The auditor's coupon will
            show the Airline's unpublished fare as authorized by PriceLine
            Travel.

     10.    In the event that Priceline is unable to fulfill a Priceline ticket
            request from unpublished fares and seat inventory provided from
            airlines participating in the Priceline Service, Priceline reserves
            the right to sell tickets on Airline using published fares used by
            travel agents generally as reflected in CRSs, in accordance with the
            rules and conditions associated with such fares.

     11.    At the request of Airline, Priceline will incorporate into the
            Priceline Service a "hot link" to the designated Internet site of
            Airline; PROVIDED, HOWEVER, that Priceline will have a reasonable
            period of time following any such request to accomplish any system
            changes, additions or enhancements necessary or appropriate for the
            inclusion of any such "hot link."

III. PRICELINE TICKET ALLOCATION METHODOLOGY

            Priceline shall establish an allocation methodology that determines
            when participating airlines will be given the first opportunity to
            fill a customer ticket request, and may give preference to one or
            more participants in establishing such methodology. Priceline will
            work in good faith with each participating airline to assist such
            airline in achieving its objective for the Priceline Service within
            the context of the allocation system.

IV.  PRICELINE CUSTOMER SERVICE; JOINT MARKETING

     1.     Priceline will provide twenty-four hour customer support services to
            all Priceline customers through a toll-free number at the customer
            support center designated by Priceline from time to time. The
            customer support center will be adequately staffed with personnel
            trained to take Priceline Ticket requests by phone and respond to
            all customer inquiries for related service and support.

     2.     Priceline will use commercially reasonable efforts to ensure that
            its customer service representatives provide quality customer
            service and support to Priceline customers in a prompt, reliable and
            courteous manner.

     3.     Priceline will respond to Priceline customer questions and issues
            pertaining to special handling requirements for Priceline Tickets
            including processing any

            special customer handling requirements in respect of Priceline
            Tickets issued on Airline.

V.   CONFIDENTIALITY

     1.     Priceline and Airline will each hold in confidence and, without the
            prior written consent of the other, will not reproduce, distribute,
            transmit, transfer or disclose, directly or indirectly, in any form,
            by any means or for any purpose, any Confidential Information of
            the other party. As used herein, the term "CONFIDENTIAL INFORMATION"
            shall mean this Agreement and its subject matter, and proprietary
            information that is provided to or obtained from one party to the
            other party including any information which derives economic value,
            actual or potential, from not being generally known to, and not
            generally ascertainable by proper means by, other persons, including
            the unpublished fares provided by Airline to Priceline pursuant to
            this Agreement. The recipient of Confidential Information may only
            disclose such information to its employees on a need-to-know basis.

     2.     The obligations of a recipient party with respect to Confidential
            Information shall remain in effect during and after the term of this
            Agreement (including any renewals or extensions hereof) and for a
            period of five (5) years thereafter, except to the extent such data:

                 (a) is or becomes generally available to the public other than
            as a result of a disclosure by the recipient, or its directors,
            officers, employees, agents or advisors,

                 (b) becomes available to the recipient on a non-confidential
            basis from a source other than the disclosing party or its
            affiliated companies, provided that such source is not bound by any
            confidentiality obligations to the disclosing party or its
            affiliated companies (as applicable); or

                 (c) is necessary to comply with applicable law or the order or
            other legal process of any court, governmental or similar authority
            having jurisdiction over the recipient.

     3.     In the event that the recipient becomes legally compelled to
            disclose any of such Confidential Information by any governmental
            body or court, recipient will provide the disclosing party with
            prompt notice so that the disclosing party may seek a protective
            order or other appropriate remedy and/or waive compliance (in
            writing) with the provisions hereof. In the event that such
            protective order or other remedy is not obtained, or the disclosing
            party waives (in writing) compli-

            ance with the provisions hereof, recipient will furnish only that
            portion of such Confidential Material which is legally required and
            will exercise its reasonable business efforts to obtain appropriate
            assurance that confidential treatment will be accorded such
            Confidential Information

     4.     The recipient of Confidential Information will exercise reasonable
            commercial care in protecting the confidentiality of the other
            party's Confidential Information.

     5.     Priceline will not disclose (including, without limitation, by sale)
            to any third party information obtained through the Priceline
            Service concerning a customer who has acquired a ticket on Airline
            using the Priceline Service.

     6.     Priceline will not identify Airline's participation in the Priceline
            Service until a customer is booked and confirmed for ticketing.
            Further, Priceline will not, in any media (including its Internet
            site), indicate that Airline is participating or has participated in
            the Priceline Service except to indicate that as a consumer
            proposition, a Priceline customer must accept a routing on one of
            the major U.S. full service airlines or, in the case of
            international travel, other airline carriers available through the
            Priceline Service. Except as set forth above, Priceline will not
            disclose Airline's participation in the Priceline Service without
            Airline's prior consent. Airline will not disclose its participation
            in the Priceline Service without Priceline Inc.'s prior consent.

VI.  PROPRIETARY MARKS

            During the term of this Agreement neither Priceline nor Airline
            shall use the other party's trademarks, trade names, service marks,
            logos, emblems, symbols or other brand identifiers in advertising or
            marketing materials, unless it has obtained the prior written
            approval of the other party. The consent required by this Paragraph
            VI shall extend to the content of the specific advertising or
            marketing items as well as the placement and prominence of the
            applicable trademark, trade name, service mark, logo, emblem, symbol
            or other brand identifier of the other party. Priceline or Airline,
            as applicable, shall cause the withholding, discontinuance, recall
            or cancellation, as appropriate, of any advertising or promotional
            material not approved in writing by the other party, that differs
            significantly from that approved by the other party, or that is put
            to a use or used in a media not approved by the other party.

                  designations, as agreed to by the parties in accordance with

                  received by LendingTree from lenders, including but not
                  limited to transmission fees and loan origination fees, as a

                  "Revenue Deductions"). The parties hereto acknowledge that in
                  the start up of this relationship, there are likely to be
                  delays in LendingTree's receipt of Revenue. As such, the

                  Revenues received at a later date.

         1.6      "Priceline Name Your Price/Conditional Purchase Model" means
                  the product distribution model utilized by Priceline on its

                  and terms under which he or she will purchase a product or
                  service, and Priceline attempts to find a seller willing to
                  sell the product or service to the consumer on the terms
                  identified by the consumer. In the context of this Agreement
                  and the Mortgage Web Pages, the term shall refer to a business

                  including interest rate, points and loan term, under which he
                  or she is willing to obtain a specified Mortgage Loan. To the
                  extent permitted by applicable law, the Priceline Name Your
                  Price/Conditional Purchase Model may include the delivery to a
                  lender by the consumer of a fee to be used by that lender to
                  offset certain third party or other related costs or expenses,
                  all or a part of which fee may be forfeited by the consumer if
                  the loan fails to close due the substantial fault of the
                  consumer. In addition, the Priceline Name Your
                  Price/Conditional Purchase Model contemplates a counteroffer
                  process, wherein a lender, although unable to offer a consumer
                  the mortgage loan on the specific terms requested, is able to
                  provide the consumer with an acceptable counteroffer.

                  utilized by LendingTree on its website wherein consumers

                  provided LendingTree with credit related criteria for use in
                  LendingTree's proprietary filtering system. The qualification
                  form along with certain credit report and credit scoring
                  information ("Consumer Information") is then presented to the
                  lenders who review that Consumer Information and bid for that
                  consumer's business.

         1.8      "Proprietary Marks" means the trade names, servicemarks,

                  lenders about the Mortgage Web Pages and opportunities to
                  offer mortgage loan products on the Mortgage Web Pages.

         3.5      LEGAL COMPLIANCE. During the term of this Agreement, Priceline
                  shall be responsible for the compliance, in all material
                  respects, with federal, state and other laws and regulations
                  generally applicable to the priceline.com Internet site,
                  including all general advertising related thereto, including
                  general unfair and deceptive trade issues, consumer protection
                  issues and customer relations issues. Under no circumstances,
                  however, will Priceline be charged with responsibility for
                  compliance with federal, state or other laws or regulations
                  applicable to mortgage brokers, the offering of Mortgage Loan
                  products or any and all disclosure, notice or other

                  compliance being the obligation of LendingTree as provided in
                  Section 4.6 of this Agreement.

4.       LENDINGTREE'S DUTIES

         4.1      MORTGAGE WEB PAGES SUBSTANTIVE CONTENT; MORTGAGE LOAN
                  BROKERAGE SERVICES. With respect to the development of the
                  Mortgage Web Pages, it is expressly acknowledged and agreed to
                  between the parties that LendingTree will provide the
                  substantive Mortgage Content of the Mortgage Web Pages
                  Qualification Form related to the Mortgage Web Pages that are
                  to be developed by Priceline. The Mortgage Web Pages will
                  constitute the "front end" of LendingTree's mortgage brokerage
                  operations at the priceline.com Internet site. To the extent
                  permitted by applicable law, the Mortgage Web Pages will
                  incorporate the LendingTree Qualification Form and the
                  Priceline Name Your Price/Conditional Purchase Model. The
                  Mortgage Web Pages will have the same "look and feel" of other
                  areas of the priceline.com Internet site. The substantive
                  Mortgage Content utilized in the design and development of the
                  Mortgage Web Pages including, but not limited to, all issues
                  related to regulatory compliance shall be subject to the
                  review and approval of Priceline and its counsel, which shall
                  not be unreasonably withheld or delayed. A fuller description
                  of the specifications is set forth in EXHIBIT B. LendingTree
                  acknowledges and agrees that the Mortgage Web Pages as
                  designed by Priceline with the substantive content to be
                  provided by LendingTree will allow Mortgage Loans to be
                  offered through the Mortgage Web Pages by LendingTree in a
                  lawful manner that does not trigger any mortgage broker or
                  loan broker license or registration (or any consumer
                  disclosures, compliance or other requirements related thereto)
                  on the part of Priceline. LendingTree will operate the
                  Mortgage Web Pages and will act as the mortgage broker in
                  connection with all Mortgage Loan products offered on or
                  through the Mortgage Web Pages. LendingTree will at all times
                  maintain in all material respects compliance with applicable
                  federal and state laws and will maintain in good standing
                  requisite mortgage broker licenses, registrations, approvals
                  and exemptions, as applicable.

         4.2      LENDER NETWORK MANAGEMENT. During the term of this Agreement,
                  LendingTree shall use best efforts to obtain and maintain
                  agreements with a sufficient number of lenders that offer
                  Mortgage Loan products through LendingTree on the Mortgage Web
                  Pages, as are necessary to support the LendingTree/Priceline
                  relationship. LendingTree agrees that lenders offering the
                  Mortgage Loan products on the Mortgage Web Pages shall,

                  collectively, have the ability to promptly and efficiently
                  process and close Mortgage Loans from Mortgage Web Pages
                  Qualification Forms, submitted from consumers/ borrowers
                  representing eighty percent (80%) of the Priceline
                  consumer/borrower market (based upon FICO credit score).
                  Subject to the foregoing, the parties currently project that
                  the appropriate number of lenders is from five (5) up to and
                  including ten (10). LendingTree agrees that the minimum number
                  of lenders shall not be less than five (5) during the term of
                  this Agreement. LendingTree will accept recommendations from
                  Priceline regarding potential participating lenders and will
                  work in good faith to enter into agreements with such lenders
                  to enable them to offer their mortgage loan products through
                  LendingTree and the Mortgage Web Pages. LendingTree will be
                  responsible for all lender service issues, training of lender
                  staff, and analyzing lender performance. LendingTree will
                  invoice lenders and manage the collection of all fees.

                  No agreement entered into between LendingTree and any
                  participating lender in connection with the Mortgage Web Pages
                  will impose any obligation, duty or responsibility whatsoever
                  on Priceline, directly or indirectly, or limit or restrict in
                  any manner any of Priceline's legal rights or remedies,
                  including, without limitation, Priceline's right to terminate
                  this Agreement under Section 11 hereof.

         4.3      CUSTOMER SERVICE. LendingTree will operate a customer service
                  center dedicated to the Mortgage Web Pages with sufficient
                  staff and resources necessary to handle the volume of customer
                  inquiries generated from the Mortgage Web Pages in a prompt
                  and efficient manner and in accordance with applicable
                  federal, state and other laws and regulations. The parties
                  will work to establish appropriate interfaces between
                  Priceline's existing customer service center and the
                  LendingTree customer service center. In addition, the parties
                  will work together to develop introductory scripts for
                  customer service calls, subject to the review and approval of
                  their respective attorneys.

         4.4      CONTENT. As set forth in Sections 3.1 and 4.1 hereof,
                  LendingTree will provide the substantive Mortgage Content for
                  use on the Mortgage Web Pages.

         4.5      BACK-END SOFTWARE. During the term of the Agreement,
                  LendingTree will provide and manage the "back-end" processing
                  software required to effect a system of communication between
                  Priceline and LendingTree and LendingTree and its lenders in
                  connection with the Mortgage Web Pages. LendingTree will
                  maintain back-end software processing capacity and reliability
                  at levels subject to the review and approval of Priceline.

         4.6      LEGAL COMPLIANCE. During the term of this Agreement,
                  LendingTree shall be responsible for compliance, in all
                  material respects, with all applicable federal, state and
                  other laws and regulations for the Mortgage Web Pages or the
                  Mortgage Loan Products offered to consumers through the
                  Mortgage Web Pages, and will maintain in good standing
                  requisite mortgage broker licenses, registration, approvals
                  and exemptions relating to any of the foregoing. In addition,
                  LendingTree will review and approve all advertising developed
                  by Priceline that is specific to the Mortgage Web Pages to
                  achieve compliance with applicable federal, state and other
                  laws and regulations governing the offering of Mortgage Loan
                  products to the consumer. Further, LendingTree shall be
                  responsible for compliance with all consumer disclosure and
                  other laws and requirements applicable to

                  all of the Mortgage Web Pages and the Mortgage Loan products
                  offered through the Mortgage Web Pages, except that should
                  Priceline launch any advertising that impacts the Mortgage Web
                  Pages, knowingly or otherwise, without LendingTree's review
                  and approval, Priceline shall be solely responsible for any
                  issues arising out of that non-compliance.

5.       EXCLUSIVITY; NON-COMPETITION

         5.1      EXCLUSIVITY. During the term of this Agreement, Priceline
                  agrees not to offer any Mortgage Loans on its web site, either
                  directly or through a third party.

         5.2      NON-COMPETITION. The parties hereto acknowledge and agree that
                  the LendingTree Model and Priceline Name Your
                  Price/Conditional Purchase Model (hereinafter, together, the
                  "Models") are similar in many of their components. To assist
                  the parties in complying with this Section 5.2, the parties
                  agree that the marketing of the Models is the optimum place to
                  draw the relevant distinctions. Consistent with the above, the
                  parties agree that during the term of this Agreement and
                  indefinitely after any termination of this Agreement, (i)
                  Priceline shall not market its mortgage services in a manner
                  that conflicts with LendingTree's marketing message which is
                  "by filling out one form, consumers get multiple offers from
                  lenders who bid for their business" and (ii) LendingTree shall
                  not market its mortgage services in a manner that conflicts
                  with Priceline's marketing message which is "consumers name
                  the price they want to pay for a mortgage and we will find a
                  lender to meet your price".

6.       TECHNICAL CONTACTS

         6.1      TECHNICAL CONTACTS. The Technical Contacts shall meet in
                  person or by phone as needed from time to time to assess the
                  status of the Mortgage Web Pages development effort and to
                  keep each other up to date on technology and new product

         The target date for commencing operation of the Mortgage Web Pages
         shall be September 15, 1998 (the "Target Date"). The parties agree to

8.       CONSIDERATION

         8.1      GENERAL. As compensation for the goods, services and
                  facilities provided by Priceline under this Agreement,
                  LendingTree shall pay to Priceline an amount equal to [**][**]
                  of the monthly Net Revenue earned and received by LendingTree
                  in operating the Mortgage Web Pages (the "Priceline
                  Compensation"). LendingTree's obligation to pay the Priceline
                  Compensation shall survive any termination of this Agreement
                  insofar and to the extent that Net Revenues are earned and/or
                  received by LendingTree after such termination. The parties
                  acknowledge, however, that for purposes of this Section 8.1,
                  Net Revenue will be limited to (i) those Mortgage Web Page
                  Qualification Forms that are in the then-participating
                  lenders' pipeline for a Mortgage Loan product, (ii) have been
                  approved for a Mortgage Loan but the transaction has not yet
                  closed and/or (iii) Net Revenue earned but not collected, in
                  each case on or as of the date of termination of this
                  Agreement.

         8.2      REGULATORY COMPLIANCE. It is the intent of the parties that
                  the Priceline Compensation shall not exceed the reasonable
                  market value of the goods, services and facilities provided by
                  Priceline pursuant to this Agreement and that such
                  compensation shall at all times be in compliance with
                  applicable federal and state laws, including without
                  limitation, the Real Estate Settlement Procedures Act. In
                  furtherance of these objectives, the parties agree to
                  negotiate in good faith an alternative compensation
                  arrangement with substantially similar economic benefits if
                  Priceline or LendingTree, as applicable, reasonably determine
                  or believe that such compensation arrangement is no longer in
                  compliance with applicable federal, state or other laws and
                  regulations, or any court or government agency having
                  jurisdiction over the operations of either party restricts,
                  enjoins, or threatens to restrict, enjoin or impose sanctions
                  against either party as a result of the terms of this Section
                  8.

                  regarding usage of the Mortgage Web Pages during the previous
                  month, including the number of visitors to the Mortgage Web
                  Pages, the number of Qualification Forms submitted by

                  completeness of all reports provided under this Section 10.1.
                  The cost of any such audit shall be paid by Priceline unless

                  LendingTree under this Section 11.3 for the purpose of using a
                  different third party mortgage broker to operate the Mortgage
                  Web Pages, LendingTree shall have a right of first refusal to
                  match the economic and other material terms offered by such
                  third party PROVIDED, HOWEVER, that any such right of first
                  refusal shall be exercised by LendingTree within ninety (90)
                  calendar days after receipt of notice from Priceline with
                  respect to such third party offer. The parties agree that the
                  phrase "other material terms" is intended to ensure that
                  during the term of this Agreement, the LendingTree network of
                  lenders have the ability to promptly and efficiently process
                  and close Mortgage Loans from Mortgage Web Pages Qualification
                  Forms submitted from consumers/borrowers representing eighty
                  percent (80%) of the Priceline consumer/borrower market (based
                  upon FICO credit score.) Priceline will be free to engage
                  another third party if such right is not exercised by notice
                  received by Priceline from LendingTree within such ninety (90)
                  day period. Subject to the limitations in Section 5 hereof,
                  nothing set forth in this Section 11.3 shall confer on or to
                  LendingTree any right of first refusal if Priceline elects to
                  operate directly the Mortgage Web Pages and in connection
                  therewith, provides notice to terminate this Agreement.

         11.4     TERMINATION FOR BREACH. During the Term of this Agreement,
                  either party will have the right to terminate this Agreement
                  immediately upon written notice if: (i) the other party
                  materially breaches any material term or condition of this
                  Agreement and fails to the cure such breach in full within
                  thirty (30) days after receiving written notice of the breach
                  from the non-breaching party; (ii) the other party becomes the
                  subject of a voluntary petition in bankruptcy or any voluntary
                  proceeding relating to insolvency, receivership, liquidation,
                  or composition for the benefit of creditors which voluntary
                  petition or proceeding is not dismissed within thirty (30)
                  days of filing of commencement; and (iii) the other party
                  becomes the subject of an involuntary petition in bankruptcy
                  or any other involuntary proceeding relating to insolvency,
                  receivership, liquidation, or composition for the benefit of
                  creditors. Without limiting the generality of the foregoing,
                  either party may terminate this Agreement immediately upon
                  notice if, in the case of Priceline, Priceline reasonably
                  believes or determines that LendingTree has failed to comply
                  in all material terms, with its obligations under Section 4.6,
                  or such noncompliance is determined by any order, decree,
                  judgment or any similar ruling having jurisdiction over
                  LendingTree's operation of the Mortgage Web Pages or, in the
                  case of LendingTree, LendingTree reasonably believes or
                  determines that Priceline has failed to comply in all material
                  terms, with its obligations under Section 3.5, or such
                  noncompliance is determined by any order, decree, judgment or
                  any similar ruling having jurisdiction over Priceline's
                  operation of the priceline.com Internet site. To the extent
                  that a breach contemplated by this Section 11.4 is curable,
                  such cure period may be extended by the mutual written consent
                  of the parties for an additional period of thirty (30) days,
                  if the cure cannot be achieved after good faith efforts during
                  the initial cure period.

         11.5     EFFECT OF TERMINATION. Upon termination of this Agreement, all
                  rights and licenses granted by Priceline and LendingTree under
                  this Agreement to the other party shall immediately revert to
                  and be fully vested in Priceline and LendingTree, as
                  applicable. No termination of this Agreement, for any reason
                  whatsoever, shall terminate any of the rights and obligations
                  of the parties under this Agreement unless such right or
                  obligation is limited by the express terms and provisions of
                  this Agreement.

12.      ARBITRATION

         Any controversy or claim arising out of or relating to this Agreement
         or any breach of this Agreement, including any controversy or claim as
         to its arbitrability or rescission shall be finally settled by
         arbitration before three (3) arbitrators, one chosen by each party and
         the third selected by the two arbitrators chosen by the parties in
         accordance with the commercial arbitration rules of the American
         Arbitration Association ("AAA") in force at that time. Any arbitration
         shall be conducted in the Borough of Manhattan, New York, unless the
         parties mutually agree to another location. Any judgment upon the award
         rendered by the arbitrators may be entered in any court of competent
         jurisdiction. The arbitrators shall not, under any circumstances, have
         any authority to award punitive or exemplary damages.

         All expenses associated with obtaining and utilizing the services of
         the AAA and the arbitrators shall be shared equally by the parties
         hereto. The AAA and the arbitrators shall be made aware of this
         provision and shall agree to request payment separately from the
         parties for said services, including all expenses directly related to
         the arbitration, other than the expense of witnesses, which shall be
         borne by the party producing such witness.

         Notwithstanding the foregoing, the parties shall bear their own
         respective costs of preparing for and participating in the arbitration
         including, without limitation, their attorneys' fees, expert and/or
         witness fees, and their costs of complying with discovery requests.
         Discovery is permitted by the Federal Rules of Civil Procedure as in
         effect and will be allowed in connection with any such arbitration to
         the extent consistent with the purpose of the arbitration and permitted
         by the arbitrators.

         The majority decision of the arbitration panel shall be binding,
         enforceable and non-appealable. The decision of the arbitration panel
         shall be in writing and shall set forth in reasonable detail the basis
         for the panel's decision. Application may be made to any court of
         competent jurisdiction for a judicial acceptance of the arbitration
         award and enforcement, as the law of the state having jurisdiction may
         require or allow.

         No arbitration may be commenced by either party hereto for any
         controversy or claim arising out of or relating to this Agreement
         unless notice of a party's election to require arbitration is given
         within one (1) year from the date of the occurrence allegedly giving
         rise to the arbitration. The preceding sentence shall survive the
         expiration or termination of this Agreement by either party for any
         reason.

                  terms of this Agreement. LendingTree has taken all necessary
                  action to authorize its execution, delivery and performance of
                  this Agreement.

         13.1.2   CONFLICT WITH EXISTING LAWS OR CONTRACTS. The execution and
                  delivery of this Agreement and the performance of its
                  obligations hereunder by LendingTree will not (i) conflict
                  with or violate (A) LendingTree's Certificate of Incorporation
                  or By-laws, or (B) any provision of any law or regulation or
                  any decree, demand or order to which LendingTree is subject,
                  or (ii) conflict with or result in a breach of or constitute a
                  default (or an event which, with notice or lapse of time, or

                  conditions or provisions of any agreement or instrument to
                  which LendingTree is a party or by which it is bound or any
                  order or decree applicable to LendingTree or result in the
                  creation or imposition of any lien on any of its assets or

                  requisite for the transactions contemplated by this Agreement.
                  No consent, approval, authorization or order of any court or
                  governmental agency or body is required for the execution,
                  delivery and performance by LendingTree of or compliance by
                  LendingTree with this Agreement, or if required, such approval
                  has been obtained prior to the date of this Agreement.

         13.1.4   LEGAL ACTION AGAINST LENDINGTREE. There is no claim, action,
                  suit, proceeding or investigation pending or, to the best of
                  LendingTree's knowledge, threatened against LendingTree which,
                  either in any one instance or in the aggregate, may result in
                  any material adverse change in the business, operations,
                  financial condition, properties or assets of LendingTree, or
                  in any material impairment of the right or ability of
                  LendingTree to carry on its business substantially as now
                  conducted, or in any material liability on the part of
                  LendingTree, or which would draw into question the validity of
                  this Agreement, or any of the other instruments, documents or
                  agreements entered into by LendingTree in connection with this
                  Agreement, or of any action taken or to be taken in connection
                  with the obligations of LendingTree contemplated therein, or
                  which would be likely to impair materially the ability of
                  LendingTree to perform under the terms of this Agreement.

         13.1.5   BINDING ON LENDINGTREE; ENFORCEABILITY. This Agreement,
                  assuming due authorization, execution and delivery hereof by
                  Priceline, and all the obligations of LendingTree hereunder,

                  LendingTree, enforceable against LendingTree in accordance
                  with the terms hereof, except as such enforcement may be
                  limited by bankruptcy, insolvency, reorganization, moratorium
                  and other similar laws affecting the enforcement of creditors'
                  rights in general and by general equity principles (regardless
                  of whether such enforcement is considered in a proceeding in
                  equity or at law).

         13.1.6   OWNERSHIP OF INTELLECTUAL PROPERTY. LendingTree owns the
                  copyright and any other rights to or has licensing rights to
                  all LendingTree Intellectual Property and to the knowledge of
                  LendingTree, such LendingTree Intellectual Property will not
                  infringe upon, misappropriate or violate any intellectual
                  property rights or any other right of any third party.

                  knowledge of LendingTree, Priceline's exercise of any such
                  rights as authorized hereunder will not constitute an
                  infringement or misappropriation of any intellectual property
                  rights of any third party.

         13.2     REPRESENTATIONS AND WARRANTIES OF PRICELINE. Priceline
                  represents and warrants as follows:

         13.2.1   AUTHORITY. Priceline is a corporation duly organized and
                  validly existing under the laws of the state of Delaware.
                  Priceline has full power and authority to transact any and all
                  business contemplated by this Agreement and possesses all
                  requisite authority, power, and material licenses, permits and
                  franchises to conduct its business wherever conducted and to
                  execute, deliver and comply with its obligations under the
                  terms of this Agreement. Priceline has taken all necessary
                  action to authorize its execution, delivery and performance of
                  this Agreement.

         13.2.2   CONFLICT WITH EXISTING LAWS OR CONTRACTS. The execution and
                  delivery of this Agreement and the performance of its
                  obligations hereunder by Priceline will not (i) conflict with
                  or violate (A) Priceline's Articles of Organization or
                  By-laws, or (B) any provision of any law or regulation or any
                  decree, demand or order to which Priceline is subject, or (ii)
                  conflict with or result in a breach of or constitute a default
                  (or an event which, with notice or lapse of time, or both,
                  would constitute a default) under any of the terms, conditions
                  or provisions of any agreement or instrument to which
                  Priceline is a party or by which it is bound or any order or
                  decree applicable to Priceline or result in the creation or
                  imposition of any lien on any of its assets or property.

         13.2.3   LICENSES AND CONSENTS. Except with respect to the mortgage
                  brokerage activity contemplated under this Agreement,
                  Priceline has obtained all necessary or required governmental
                  licenses and consents to the transactions contemplated by this
                  Agreement. Except with respect to the mortgage brokerage
                  activity contemplated under this Agreement, no consent,
                  approval, authorization or order of any court or governmental
                  agency or body is required for the execution, delivery and
                  performance by Priceline of or compliance by Priceline with
                  this Agreement, or if required, such approval has been
                  obtained prior to the date of this Agreement.

         13.2.4   LEGAL ACTION AGAINST PRICELINE. There is no claim, action,
                  suit, proceeding or investigation pending or, to the best of
                  Priceline's knowledge, threatened against Priceline which,
                  either in any one instance or in the aggregate, may result in
                  any material adverse change in the business, operations,
                  financial condition, properties or assets of Priceline, or in
                  any material impairment of the right or ability of Priceline
                  to carry on its business substantially as now conducted, or in
                  any material liability on the part of Priceline, or which
                  would draw into question the validity of this Agreement or any
                  of the other instruments, documents or agreements entered into
                  by Priceline in connection with this Agreement, or of any
                  action taken or to be taken in connection with the obligations
                  of Priceline contemplated therein, or which would be likely to
                  impair materially the ability of Priceline to perform under
                  the terms of this Agreement.

         13.2.5   BINDING ON PRICELINE; ENFORCEABILITY. This Agreement, assuming
                  due authorization, execution and delivery hereof by
                  LendingTree, and all the obligations of Priceline

                                       13

                  hereunder, shall constitute the legal, valid and binding
                  obligations of Priceline, enforceable against Priceline in
                  accordance with the terms hereof, except as such enforcement
                  may be limited by bankruptcy, insolvency, reorganization,
                  moratorium and other similar laws affecting the enforcement of
                  creditors' rights in general and by general equity principles
                  (regardless of whether such enforcement is considered in a
                  proceeding in equity or at law).

         13.2.6   OWNERSHIP OF INTELLECTUAL PROPERTY. Priceline owns the
                  copyright and any other rights to or has licensing rights to
                  all Priceline Intellectual Property and to the knowledge of
                  Priceline, such Priceline Intellectual Property does not
                  infringe upon, misappropriate or violate any intellectual
                  property rights or any other right of any third party.
                  Priceline has sufficient rights to the Intellectual Property
                  to grant to LendingTree the rights set forth in this
                  Agreement, and to the knowledge of Priceline, LendingTree's
                  exercise of any such rights as authorized hereunder will not
                  constitute an infringement or misappropriation of any
                  intellectual property rights of any third party.

14.      INDEMNIFICATION; LIMITATION OF LIABILITY

         14.1     INDEMNIFICATION FOR ACTIONS TAKEN IN GOOD FAITH. Neither

                  against, any action taken by the LendingTree Indemnified

                  hold harmless any LendingTree Indemnified Party from or
                  against, any liability that would otherwise be imposed by

                  in the performance of or failure to perform LendingTree's
                  obligations hereunder.

                  Parties, or for their refraining from taking any action, in
                  good faith reliance upon information provided by LendingTree,
                  pursuant to this Agreement; PROVIDED, HOWEVER, that this 
                  provision shall not protect any Priceline Indemnified Party 
                  against, and LendingTree shall not be obligated to indemnify 
                  or hold harmless any Priceline Indemnified Party from or 
                  against, any liability that would otherwise be imposed by

                  in the performance of or failure to perform Priceline's 
                  obligations hereunder.

                  expenses (each, a "Liability") that were caused by or resulted
                  from, or are otherwise arising from or related to, a breach of
                  any of LendingTree's duties, representations, warranties,
                  covenants and agreements contained in this Agreement, the
                  LendingTree Intellectual Property, or by LendingTree

                  misfeasance, bad faith, or negligence in the performance of or
                  failure to perform as provided in this Agreement.

                  Section 12 of this Agreement, Priceline's and LendingTree's
                  respective obligations to indemnify any LendingTree
                  Indemnified Party or any Priceline Indemnified Party will
                  survive the expiration or termination of this Agreement by
                  either party for any reason.

         14.6     LIMITATIONS OF LIABILITY; CONSEQUENTIAL DAMAGES. EXCEPT AS
                  EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PARTIES DISCLAIM
                  ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT
                  LIMITATION, ANY IMPLIED WARRANTIES WITH RESPECT TO THE
                  OPERATION OF THE SOFTWARE UTILIZED FOR THE MORTGAGE WEB PAGES,
                  THE MERCHANTABILITY OF SUCH SOFTWARE OR THE FITNESS OF THE
                  SOFTWARE FOR A PARTICULAR PURPOSE OR USE. NEITHER PARTY SHALL
                  BE LIABLE TO THE OTHER PARTY UNDER THIS AGREEMENT FOR ANY
                  LIABILITY WHATSOEVER, FOR ANY INDIRECT, INCIDENTAL, SPECIAL OR
                  CONSEQUENTIAL DAMAGES (UNDER CONTRACT OR TORT THEORIES OF
                  LAW), INCLUDING BUT NOT LIMITED TO LOST DATA, LOST REVENUE OR
                  PROFITS OR LOST BUSINESS, HOWEVER ARISING, EVEN IF IT HAS BEEN
                  ADVISED OF OR HAS FORESEEN THE POSSIBILITY OF SUCH DAMAGES.

         14.7     LIMITATION ON LIABILITY OF OFFICERS, DIRECTORS, MEMBERS,
                  EMPLOYEES AND AGENTS. Neither party shall make any claim
                  against the officers, directors, members, employees or agents
                  of the other party but instead shall look solely to the assets
                  of the other party for satisfaction of any liability of such
                  party under this Agreement.

         14.8     NOTICE OF CLAIMS. Each party shall promptly notify the other
                  in writing of any and all litigation, claims, notices or
                  demands known to such party made against it or the other party
                  in connection with this Agreement. Each party shall cooperate
                  with the other in the defense or handling of any claim, action
                  or investigation relating to the subject matter of this
                  Agreement, provided that such cooperation shall not be deemed
                  an acceptance of responsibility therefor, except as provided
                  below. Any request for indemnification under this paragraph
                  shall be in writing and shall state with particularity the
                  specific facts supporting the request for indemnification and
                  a good faith estimate of the amount of the indemnification
                  requested. In the event responsibility for a request for

                                       15
<PAGE>




                  indemnification hereunder is unconditionally accepted in
                  writing, the party accepting such responsibility may, at its
                  option, elect to take up the defense or handling of any
                  pending claim, action or investigation and, in such event, the
                  party requesting indemnification shall promptly relinquish
                  control of such defense to the accepting party. Unless and
                  until a request for indemnification hereunder is
                  unconditionally accepted, the requesting party may retain
                  control of the defense or handling of the claim, action or
                  investigation. The failure of a party to accept a request for
                  indemnification under this paragraph shall not be binding upon
                  the requesting party and such party's retention of the control
                  of the defense or handling of the claim, action or
                  investigation shall not prejudice its right to seek
                  enforcement of this paragraph in court.

15.      CHOICE OF LAW

         15.1     CHOICE OF LAW. The parties agree that this Agreement shall be
                  construed and controlled by the laws of the State of New York
                  and the Commercial Arbitration Rules of the AAA. Should a
                  dispute arise under this Agreement, and should the arbitration
                  provisions herein become inapplicable, the parties agree that
                  jurisdiction over and venue of any suit arising out of or
                  relating to this Agreement shall be exclusively in the state
                  and federal courts of New York.

         15.2     ATTORNEYS' FEES. If either party employs attorneys to enforce
                  any right arising out of or relating to this Agreement, the
                  prevailing party shall be entitled to recover reasonable
                  attorneys' fees, in arbitration, litigation, or otherwise.

                  No notice of change of address shall be effective unless made
                  in compliance with this Section 16.1.

         16.2     ASSIGNMENT. This Agreement shall not be assignable in whole or
                  in part by LendingTree or Priceline without the other party's
                  prior written consent, and any attempted assignment without
                  such consent shall be void. Subject to the foregoing, this
                  Agreement shall be binding upon and shall inure to the benefit
                  of the parties hereto and their respective successors and
                  permitted assigns. A change in control of either party, for
                  example, by merger or sale of stock, shall not be deemed to be
                  an assignment under this Agreement.

         16.3     WAIVER. No term or provision hereof will be deemed waived, and
                  no variation of terms or provisions hereof shall be deemed
                  consented to, unless such waiver or consent shall be in
                  writing and signed by the party against whom such waiver or
                  consent is sought to be enforced. Any delay, waiver or
                  omission by LendingTree or Priceline to exercise any right or
                  power arising from any breach or default of the other party in
                  any of the terms, provisions or covenants of this Agreement
                  shall not be construed to be a waiver by LendingTree or
                  Priceline of any subsequent breach or default of the same or
                  other terms, provisions or covenants on the part of either
                  party.

         16.4     ENTIRE AGREEMENT. This Agreement constitutes the entire
                  agreement between the parties hereto relating to the subject
                  matter hereof, except where expressly noted herein, and all
                  prior negotiations, agreements and understandings, whether
                  oral or written, are superseded or canceled hereby.

         16.5     MODIFICATION. This Agreement and all Exhibits hereto may not
                  be amended or modified except by a writing signed by both
                  parties.

         16.6     SEVERABILITY. If any provision of this Agreement is declared
                  or found to be illegal, unenforceable or void, this Agreement
                  shall be construed as if not containing that provision, and
                  the rest of the Agreement shall remain in full force and
                  effect, and the rights and obligations of the parties hereto
                  shall be construed and enforced accordingly.

         16.7     INDEPENDENT CONTRACTOR. Each party, in performance of this
                  Agreement, is acting as an independent contractor, is not the
                  partner, joint venturer or agent of the other party and has no
                  authority to act on behalf of the other party except as
                  expressly provided in this Agreement.

         16.8     CONFIDENTIALITY. Each party agrees to keep all information
                  related to the other party confidential, as provided in the
                  Mutual Confidentiality Agreement signed by the parties on July
                  8, 1998. The provisions of the Mutual Confidentiality
                  Agreement shall continue in and during the Term and shall
                  survive termination of this Agreement for any reason
                  whatsoever.

         16.9     INJUNCTIVE RELIEF. The parties acknowledge and agree that
                  their respective remedies at law for any breach by the other
                  party of its obligations hereunder may be inadequate, and the
                  parties agree and consent that temporary and permanent
                  injunctive relief may be

                  granted in any action or proceeding which may be brought to
                  enforce any provision hereof without the necessity of proof of
                  actual damages.

         16.10    DELAYS BEYOND CONTROL. Neither party will be liable for any
                  delay or failure of performance of any of its obligations
                  under this Agreement, except for the obligation to pay money,
                  during any period in which such performance is delayed by (i)
                  war, civil commotion and riots, fires, floods, serious work
                  stoppages; (ii) requirements or acts of any governmental
                  authority or agency or subdivision thereof; or (iii) acts of
                  God; PROVIDED, HOWEVER, that the nonperforming party shall
                  promptly notify the other party of any such delay and shall
                  use its best efforts to resume performance as soon as
                  reasonably possible.

         16.11    COUNTERPARTS. This Agreement may be executed in counterparts,
                  each of which shall be deemed an original, but all of which
                  together shall constitute one and the same agreement.

                  CONFIDENTIAL TREATMENT HAS BEEN REQUESTED FOR

                    PORTIONS HAVE BEEN FILED SEPARATELY WITH
                     THE SECURITIES AND EXCHANGE COMMISSION


THE WARRANT ISSUED PURSUANT TO THIS PARTICIPATION WARRANT HAS NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS. IT MAY
NOT BE SOLD OR OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED
IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT AND

                         PARTICIPATION WARRANT AGREEMENT
                       To Purchase Shares of Common Stock
                           Dated as of August 31, 1998

                           PRICELINE.COM INCORPORATED
                             a Delaware Corporation

                                                     Issue Date: August 31, 1998

                  THIS CERTIFIES THAT, Delta Air Lines, Inc. (the "Warrant
Holder"), with a place of business at 1030 Delta Boulevard, Hartsfield Atlanta
International Airport, Atlanta, Georgia 30320, for value received, is entitled,
upon the terms and subject to the conditions of this Participation Warrant
Agreement (this "Warrant Agreement"), to subscribe for and purchase fully-paid
and non-assessable shares of common stock, par value $.01 per share (the "Common
Stock"), of Priceline.com Incorporated, a Delaware corporation (the "Company").

1. ISSUANCE OF WARRANTS. On the Issue Date, the Company will issue to the
Warrant Holder warrants (the "Warrants") to acquire Fifteen Million One Hundred
Fourteen Thousand and Eighty-Three (15,114,083) shares of the Common Stock (the
"Shares"), subject to adjustment as hereinafter provided pursuant to Section 10
herein, which Shares, when issued on a proforma basis, represent 12.5% of the
Fully Diluted Equity (as defined below) of the Company as of the date hereof. As
used in this Warrant Agreement, the term "Fully Diluted Equity" of the Company
shall mean the sum of (i) the number of shares of Common Stock issued and
outstanding as of the date of this Warrant Agreement, (ii) assuming the full
conversion of all Series A Convertible Preferred Stock, par value $.01 per share
(the "Convertible Preferred"), issued and outstanding as of the date of this
Warrant Agreement, the number of shares of Common Stock issuable upon conversion
of such Convertible Preferred, and (iii) assuming the full vesting and exercise
of all options and warrants granted or issued by the Company outstanding as of
the date of this Warrant Agreement to acquire shares of its Common Stock, the
number of shares of Common Stock issuable upon such vesting and exercise. The


[**] = Confidential treatment requested for redacted portions.




<PAGE>



number of Shares subject to the Warrants shall be reduced at the time of the
effectiveness of an initial registration statement covering Common Stock filed
with the Securities and Exchange Commission to take into account the effect of
the treasury stock method of accounting for stock options and warrants. The
amount of such reduction shall be equal to the product of (i) the quotient of
(x) the aggregate exercise price of all the Company stock options and warrants
(including the Warrants), divided by (y) the greater of $5.00 or the public
offering price per share of such offering, multiplied by (ii) .125.

2. EXERCISE PRICE. The Warrants have an exercise price of $1.156862 per share of
Common Stock, as adjusted pursuant to the provisions of Section 10 of this
Warrant Agreement (the "Exercise Price").

3. TERM. Except as otherwise provided for herein, the term of the Warrants and
the right to purchase Shares as granted herein shall be exercisable, at any time
and from time to time, during the period commencing on the Issue Date set forth
above and terminating at 5:00 p.m. New York City local time on the seventh
anniversary of the Issue Date, PROVIDED, HOWEVER, that if the Company has not
completed an initial public offering of shares of Common Stock of the Company
pursuant to an effective Registration Statement under the Securities Act of
1933, as amended ("IPO"), prior to such termination date, then the term of the
Warrants shall be extended on a year to year basis until such time as the
Company has completed its IPO.

4.       VESTING.

                  a. VESTING OF THE FIRST 5% OF EQUITY. The Warrants will begin
to vest when the Company has sold at least $30 million (the "Base Amount") of
tickets issued for travel on the Warrant Holder and/or on the Warrant Holder's
code share partners (such amount being measured by the amount paid by the
Company to the Warrant Holder and its code share partners net of federal excise
taxes on such amount) ("Net Fares") during the period beginning the date hereof
and ending on December 31, 1999 or during calendar years 2000 or 2001 (each, a
"Measuring Period"). The Warrant Holder will earn the right to exercise Warrants
to acquire 1,511,408.25 Shares, subject to adjustment as hereinafter provided
pursuant to Section 10 herein (which Shares, when issued on a proforma basis,
represent approximately 1.25% of the Fully Diluted Equity of the Company as of
the date hereof), for each $5 million in Net Fares over the Base Amount during
each applicable Measuring Period up to a maximum of $50 million in Net Fares, at
which point the Warrant Holder will have earned the right to exercise Warrants
to acquire 6,045,633 Shares (which Shares, when issued on a proforma basis,
represent approximately 5% of the Fully Diluted Equity of the Company as of the
date hereof).

                  b. VESTING OF NEXT 1.25% OF EQUITY. After the Warrant Holder
has achieved $50 million in Net Fares during any applicable Measuring Period,
the Warrant Holder will earn the right to exercise Warrants to acquire up to an
additional 1,511,409 Shares, subject to adjustment as hereinafter provided
pursuant to Section 10 herein (which Shares, when issued on a proforma basis,
represent approximately 1.25% of the Fully Diluted Equity of the Company as of
the date hereof), for the next $22.5 million in Net Fares during such Measuring
Period. The actual number of Shares the Warrant Holder will earn shall be a
number equal to the product of (a) 1,511,409 Shares, multiplied by


[**] = Confidential treatment requested for redacted portions.



                                        2

<PAGE>



(b) a fraction, the numerator of which shall be Net Fares during a Measuring
Period over $50 million (up to a maximum of $22.5 million) and the denominator
of which shall be $22.5 million.

                  c. VESTING OF REMAINING 6.25% OF EQUITY. After the Warrant
Holder has achieved $72.5 million in Net Fares during any applicable Measuring
Period, the Warrant Holder will earn the right to exercise Warrants to acquire
up to an additional 7,557,041 Shares, subject to adjustment as hereinafter
provided pursuant to Section 10 herein (which Shares, when issued on a proforma
basis, represent approximately 6.25% of the Fully Diluted Equity of the Company
as of the date hereof), based on the Qualified Ticket Volume (as defined below)
of sales thereafter achieved. The actual number of Shares the Warrant Holder
will earn shall be a number equal to the product of (a) 7,557,041 Shares
(subject to adjustment as set forth in Section 10 herein) multiplied by (a) a
fraction the numerator of which shall be the actual Qualified Ticket Volume so
achieved during the applicable Measurement Period and the denominator of which
shall be $112.5 million. As used herein, the term "Qualifying Ticket Volume"
shall mean the Net Fares derived from ticket sales on the Warrant Holder and/or
its code share partners on which the Company earns a Gross Margin (as defined
below) of at least [**]; PROVIDED, HOWEVER, that if the Company's total Gross
Margin on such ticket sales during such applicable Measuring Period is greater
than or equal to [**], then all such ticket sales during such Measuring Period
will be deemed to be Qualifying Ticket Volume. As used herein, the term "Gross
Margin" on a ticket sale shall mean the number equal to (for each ticket sale)
100 times the quotient of (a) the price paid by the customer to the Company for
the ticket, less credit card charges incurred by the Company and less the Net
Fares paid by the Company to the Warrant Holder, divided by (b) the price paid
by the customer to the Company for the ticket.

                  d. ADJUSTMENT OF THRESHOLDS. The $22.5 million and $72.5
million thresholds used in the calculations set forth in Sections 4(b) and 4(c)
above (the "Thresholds") for any Measuring Period will be adjusted for such
applicable Measuring Period and for subsequent Measuring Periods, if any, in the
event that an airline, not presently participating in the Company' airline
service, commences participation at any time during such applicable Measuring
Period, and such additional carrier has a domestic market share of at least 5%
at the time of its initial participation (an "Adjustment Event"). Upon the
occurrence of an Adjustment Event, each of the Thresholds will be adjusted by
multiplying each such number by a fraction, the denominator of which shall be
the sum of the Warrant Holder's domestic market share and the aggregate domestic
market share of the new additional carrier and all other carriers participating
in the Company's airline service, and the numerator of which shall be Warrant
Holder's domestic market share. All market share data required by this Section
4(d) shall be based on U.S. domestic revenue passenger miles as reported by the
Department of Transportation on Form 41 for the twelve (12) month period
immediately prior to the time of the Adjustment Event. The resulting numbers
shall be the adjusted Thresholds. The Thresholds as set forth herein shall be
adjusted each time, if any, that an additional carrier meeting the 5% domestic
market share criteria commences participation in the Company's airline service.

                  e. MEASURING PERIODS SEPARATE NOT CUMULATIVE. Net Fares and
Qualifying Ticket Volume during each Measuring Period will be measured
separately, not cumulatively. For example, if the Warrant Holder has Net Fares
of $40 million during the first Measuring Period and Net Fares of $45 million
during the second Measuring Period, then the Warrant Holder will earn the right
to exercise Warrants for 2.5% of the Fully Diluted Equity at the end of the
First Measuring Period and


[**] = Confidential treatment requested for redacted portions.



                                        3

<PAGE>



the right to exercise Warrants for an additional 1.25% of the Fully Diluted
Equity at the end of the second Measuring Period. As a further example, if the
Warrant Holder has Net Fares of $72.5 million during the first Measuring Period,
Qualifying Ticket Volume of $36 million during the second Measuring Period (so
that the sum of Net Fares and Qualifying Ticket Volume during the second
Measuring Period is $108.5 million) and Qualifying Ticket Volume of $54 million
during the third Measuring Period (so that the sum of Net Fares and Qualifying
Ticket Volume during the third Measuring Period is $126.5 million), then the
Warrant Holder will have earned the right to exercise Warrants covering 6.25% of
the Fully Diluted Equity at the end of the first Measuring Period an additional
2% of the Fully Diluted Equity at the end of the second Measuring Period and an
additional 1% of the Fully Diluted Equity at the end of the third Measuring
Period, for an aggregate of 9.25% of the Fully Diluted Equity. For purposes of
these examples, it is assumed that neither an Adjustment Event nor any
adjustment pursuant to Section 10 hereof has occurred.

5. CALL UNDER CERTAIN CONDITIONS. The Company will have the right under certain
conditions to repurchase Warrants to acquire up to 7,557,041 Shares or the
equivalent number of Shares if such Warrants have been exercised, subject to
adjustment as hereinafter provided pursuant to Section 10 herein (which Shares,
when issued on a proforma basis, represent approximately 6.25% of the Fully
Diluted Equity of the Company as of the date hereof), in the event that the
conditions under Sections 5(a) and 5(b) below are met.

                  a. FIRST CALL. In the event that Qualified Ticket Volume
during the second Measurement Period is less than Qualified Ticket Volume during
the first Measurement Period, then the Company will have a call on that number
of Warrants calculated as follows. First, the amount of equity that the Warrant
Holder would have received, had the calculations made in Section 4(c) been made
as though the Qualifying Ticket Volume in each of the first and second
Measurement Periods had been based on the two-year average of the Qualified
Ticket Volume from such periods, will be calculated (the "First Two Year Equity
Amount"). Then, if the amount of equity the Warrant Holder has actually earned
exceeds the First Two Year Equity Amount, the Company will have a call on the
amount of such excess at the Warrant Holder's cost; PROVIDED, HOWEVER, that the
right to exercise Warrants to acquire the first 7,557,041 of Shares, subject to
adjustment as hereinafter provided pursuant to Section 10 herein, and the
underlying Shares therefor (which Shares, when issued on a proforma basis,
represent approximately 6.25% of the Fully Diluted Equity of the Company as of
the date hereof) earned by the Warrant Holder will not be subject to such call.

                  b. SECOND CALL. In the event that Qualified Ticket Volume
during the third Measurement Period is less than Qualified Ticket Volume during
the second Measurement Period, then the Company will have a call on that number
of Warrants calculated as follows. First, the amount of equity that the Warrant
Holder would have received, had the calculations made in Section 4(c) been made
as though the Qualifying Ticket Volume in each of the second and third
Measurement Periods had been based on the two-year average of the Qualified
Ticket Volume from such periods, will be calculated (the "Second Two Year Equity
Amount"). Then, if the amount of equity the Warrant Holder has actually earned
(if any), net of any Warrants subject to the call set forth in Section 5(a)
above, exceeds the Second Two Year Equity Amount, the Company will have a call
on the amount of such excess at the Warrant Holder's cost; PROVIDED, HOWEVER,
that the right to exercise Warrants to acquire the first 7,557,041 of Shares,
subject to adjustment as hereinafter provided pursuant to Section


[**] = Confidential treatment requested for redacted portions.



                                        4

<PAGE>



10 herein, and the underlying Shares therefor (which Shares, when issued on a
proforma basis, represent approximately 6.25% of the Fully Diluted Equity of the
Company as of the date hereof) earned by the Warrant Holder will not be subject
to such call.

6.       EXERCISE OF PURCHASE RIGHTS.

                  a. EXERCISE. Subject to the provisions of Section 4 of this
Warrant Agreement, the purchase rights represented by this Warrant Agreement are
exercisable by the Warrant Holder, in whole or in part, at any time, or from
time to time during the period set forth in Section 3 above, by tendering to the
Company at its principal office: a duly completed and executed notice of
exercise in the form attached hereto as EXHIBIT A (the "Notice of Exercise"),
the Warrants and the Exercise Price. Upon receipt of such items in accordance
with the terms set forth below, the Company shall issue to the Warrant Holder a
certificate for the number of shares of Common Stock purchased. The Warrant
Holder, upon exercise of the Warrants, shall be deemed to have become the holder
of the Shares represented thereby (and such Shares shall be deemed to have been
issued) immediately prior to the close of business on the date or dates upon
which the Warrants are exercised. In the event of any exercise of the rights
represented by the Warrants, certificates for the Shares so purchased shall be
delivered to the Warrant Holder or its designee as soon as practical and in any
event within ten (10) business days after receipt of such notice and, unless the
Warrants have been fully exercised or expired, new Warrants representing the
remaining portion of the Warrants and the underlying Shares, if any, with
respect to which this Warrant Agreement shall not then have been exercised shall
also be issued to the Warrant Holder as soon as possible and in any event within
such ten-day period.

                  b. METHOD OF EXERCISE. The purchase rights hereby represented
may be exercised, at the election of the Warrant Holder, by the tender of the
Notice of Exercise and the surrender of this Warrant Agreement at the principal
office of the Company and by the payment to the Company, by check, cancellation
of indebtedness or other form of payment acceptable to the Company, of an amount
equal to the then applicable Exercise Price per share multiplied by the number
of Shares then being purchased.

7. RESERVATION OF SHARES. The Company will at all times have authorized and
reserved a sufficient number of shares of Common Stock to provide for the
exercise of the rights to purchase the Shares as provided in this Warrant
Agreement. All of the Shares shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable, and free and
clear of all preemptive rights.

8. NO FRACTIONAL SHARES. No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of the Warrant Holder's rights to
purchase the Shares.

9. NO RIGHTS AS SHAREHOLDER. This Warrant Agreement does not entitle the Warrant
Holder to any voting rights or other rights as a shareholder of the Company
prior to the exercise of the Warrant Holder's rights to purchase the Shares as
provided for herein.

10. ADJUSTMENT RIGHTS. The Exercise Price and the number of shares of Common
Stock purchasable hereunder are subject to adjustment from time to time, as
follows:


[**] = Confidential treatment requested for redacted portions.



                                        5

<PAGE>




                  a. MERGER. If at any time there shall be a merger or
consolidation of the Company with or into another corporation when the Company
is not the surviving corporation, then, as part of such merger or consolidation,
lawful provision shall be made so that the holder of the Warrants evidenced
hereby shall thereafter be entitled to receive upon exercise of rights herein
granted, during the period specified herein and upon payment of the aggregate
Exercise Price, the number of shares of stock or other securities or property of
the successor corporation resulting from such merger or consolidation, to which
a holder of the stock deliverable upon exercise of the rights granted in this
Warrant Agreement would have been entitled in such merger or consolidation if
such rights had been exercised immediately before such merger or consolidation.
In any such case, appropriate adjustment shall be made in the application of the
provisions of this Warrant Agreement with respect to the rights and interests of
the holder after the merger or consolidation.

                  b. RECLASSIFICATION, ETC. If the Company at any time shall, by
subdivision, combination or reclassification of securities or otherwise, change
any of the securities as to which purchase rights under this Warrant Agreement
exist into the same or a different number of securities of any other class or
classes, this Warrant Agreement shall thereafter represent the right to acquire
such number and kind of securities as would have been issuable as the result of
such change with respect to the securities which were subject to the purchase
rights under this Warrant Agreement immediately prior to such subdivision,
combination, reclassification or other change.

                  c. SPLIT, SUBDIVISION OR COMBINATION OF SHARES. If the Company
at any time shall split or subdivide its Common Stock, the Exercise Price shall
be proportionately decreased and the number of Shares issuable pursuant to this
Warrant Agreement shall be proportionately increased. If the Company at any time
shall combine or reverse split its Common Stock, the Exercise Price shall be
proportionately increased and the number of Shares issuable pursuant to this
Warrant Agreement shall be proportionately decreased.

                  d. STOCK DIVIDENDS. If the Company at any time shall pay a
dividend payable in Common Stock, then the Exercise Price shall be adjusted,
from and after the date of determination of stockholders entitled to receive
such dividend, to that price determined by multiplying the Exercise Price in
effect immediately prior to such date of determination by a fraction (i) the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend and (ii) the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
after such dividend. The Warrant Holder shall thereafter be entitled to
purchase, at the Exercise Price resulting from such adjustment, the number of
shares of Common Stock (calculated to the nearest whole share) obtained by
multiplying (i) the Exercise Price in effect immediately prior to such
adjustment by (ii) the number of shares of Common Stock issuable upon the
exercise hereof immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

                  e. ISSUE OF ADDITIONAL STOCK. For so long as the term of this
Warrant Agreement has not expired, upon each issuance or sale (or deemed
issuance or sale) by the Company of any additional shares of Common Stock (or
securities convertible or exercisable into Common Stock) which results or would
have resulted in a reduction in the Conversion Price of the Convertible

                                        6

Preferred (as each such term is defined in the Company's Certificate of the
Powers, Designations, Preferences and Rights of the Series A Convertible
Preferred Stock (the "Certificate of Designation")) under Section 7(d)(ii) of
the Company's Certificate of Designation, then the Exercise Price in effect
immediately prior to each such issuance or sale shall, upon such issue or sale,
be reduced by a percentage equal to the same percentage that the applicable
Conversion Price has been reduced (or would have been reduced) as a result of
such issuance or sale.

                  f. EXCESS OPTION ADJUSTMENT. If General Atlantic Partners 48,
L.P., a Delaware limited partnership, and GAP Coinvestment Partners, L.P., a New
York limited partnership (together, the "Purchasers") receive additional shares
of Convertible Preferred in payment of Reimbursement Amounts (as such term is
defined in that certain Stock Purchase Agreement, dated July 31, 1998 among the
Company and the Purchasers (the "Stock Purchase Agreement")) owed to such
Purchasers under Section 2.4 of the Stock Purchase Agreement, then Warrant
Holder shall simultaneously receive that number of additional Warrants with an
exercise price of zero dollars equal to the product of (x) 0.874218 and (y) the
number of shares of Convertible Preferred received by the Purchasers pursuant to
such Section 2.4. Such Warrants will vest proportionally to the other Warrants
issued to Warrant Holder. The Company agrees that the provisions of Section 2.4
of the Stock Purchase Agreement will not be amended or changed in any way
without the express consent of the Warrant Holder.

                  g. NOTICE OF ADJUSTMENTS; NOTICES. Whenever the Exercise Price
or number of shares purchasable hereunder shall be adjusted pursuant to Section
6 hereof, the Company shall issue a certificate signed by its Chief Executive
Officer or Chief Financial Officer setting forth, in reasonable detail, the
event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated and the Exercise Price and number of shares
purchasable hereunder after giving effect to such adjustment, and shall cause a
copy of such certificate to be mailed (by first class mail, postage prepaid) to
the holder of this Warrant.

                  h. NO CHANGE OF WARRANT NECESSARY. Irrespective of any
adjustment in the Exercise Price or in the number or kind of securities issuable
upon exercise of the Warrant, unless the Warrant Holder otherwise requests, this
Warrant Agreement may continue to express the same price and number and kind of
shares of Common Stock as are stated in this Warrant Agreement as initially
executed.

11. REDEMPTION. Subject to the Company's repurchase rights prescribed in Section
5 hereof, the Warrants represented by this Warrant Agreement are not redeemable
by the Company.

12. COMPLIANCE WITH SECURITIES ACT; TRANSFERABILITY OF WARRANT OR SHARES OF
COMMON STOCK.

                  a. COMPLIANCE WITH SECURITIES ACT. The Warrant Holder, by
acceptance hereof, agrees that the Warrants, and the shares of Common Stock to
be issued upon exercise of the Warrants, are being acquired for investment and
that such Warrant Holder will not offer, sell or otherwise dispose of the
Warrants, or any shares of Common Stock to be issued upon exercise of the
Warrants except under circumstances which will not result in a violation of the
Securities Act of 1933, as amended (the "Securities Act"), or any applicable
state securities laws. The Warrants and all shares

                  LAW. THEY MAY NOT BE SOLD OR OFFERED FOR SALE, PLEDGED,

Agreement. The Warrants and all shares of Common Stock issued upon exercise of
the Warrants shall be stamped or imprinted with an additional legend
substantially in the following form.

                  "THE SALE, ASSIGNMENT, HYPOTHECATION, PLEDGE, ENCUMBRANCE OR
                  OTHER DISPOSITION (EACH A "TRANSFER") AND VOTING OF ANY OF THE
                  SECURITIES REPRESENTED BY THIS CERTIFICATE ARE RESTRICTED BY
                  THE TERMS OF THE STOCKHOLDERS AGREEMENT, DATED JULY 31, 1998,
                  AMONG PRICELINE.COM INCORPORATED AND THE STOCKHOLDERS NAMED
                  THEREIN, AS AMENDED. THE COMPANY WILL NOT REGISTER THE
                  TRANSFER OF SUCH SECURITIES ON THE BOOKS OF THE COMPANY UNLESS
                  AND UNTIL THE TRANSFER HAS BEEN MADE IN COMPLIANCE WITH THE

                  c. EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANTS. The

surrender of the Warrants to the Company with the Assignment Form annexed hereto
as EXHIBIT B duly executed, and funds sufficient to pay any transfer tax, the
Company shall, without charge, execute and deliver a new Warrant Agreement in
the name of the heir, devisee or assignee named in such instrument of assignment
and this Warrant Agreement shall promptly be canceled.

13.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company hereby incorporates herein the representations and
warranties made by the Company to the Purchasers in the Stock Purchase Agreement
and extends such representations and warranties to the Warrant Holder. The
Company expressly confirms to the Warrant Holder that such representations and
warranties are true and correct at and on the date hereof as if made at and on
such date as modified by this Warrant Agreement.

14.      REPRESENTATIONS AND WARRANTIES OF THE WARRANT HOLDER.

         The Warrant Holder hereby represents and warrants to the Company as
follows:

                  a. EXISTENCE AND POWER. The Warrant Holder is a (i) is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation and (ii) has the corporate power and
authority to execute, deliver and perform its obligations under this Warrant
Agreement.

                  b. AUTHORIZATION; NO CONTRAVENTION. The execution, delivery
and performance by the Warrant Holder of this Warrant Agreement and the
transactions contemplated hereby (i) have been duly authorized by all necessary
corporate action of the Warrant Holder and (ii) do not contravene the terms of
the Certificate of Incorporation or By-laws of the Warrant Holder, each as
amended as of and through the Issue Date.

                  c. GOVERNMENTAL AUTHORIZATION; THIRD PARTY CONSENTS. No
approval, consent, compliance, exemption or authorization of any governmental
authority or agency, or of any other person or entity, is necessary or required
in connection with the execution, delivery or performance by, or enforcement
against, the Warrant Holder of this Warrant Agreement or the transactions
contemplated hereby.

                  d. BINDING EFFECT. This Warrant Agreement has been duly
executed and delivered by the Warrant Holder and constitutes the valid and
binding obligations of the Warrant Holder, enforceable against it in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,
moratorium or similar laws affecting the enforcement of creditors' rights
generally or by equitable principles relating to enforceability (regardless of
whether considered in a proceeding at law or in equity).

                  e. PURCHASE FOR OWN ACCOUNT. The Warrants issued to the
Warrant Holder pursuant to this Warrant Agreement, and the Shares to be issued
upon vesting and exercise thereof, are being or will be acquired for the Warrant
Holder's own account and with no intention of distributing or


[**] = Confidential treatment requested for redacted portions.



                                        9

<PAGE>



reselling such securities or any part thereof in any transaction that would be
in violation of the securities laws of the United States of America, or any
state.

                  f. RESTRICTED SECURITIES. The Warrant Holder understands that
the Warrants and the Shares issuable upon vesting and exercise of the Warrants,
will not be registered at the time of their issuance under the Securities Act
for the reason that the sale provided for in this Agreement is exempt pursuant
to Section 4(2) of the Securities Act and that reliance of the Company on such
exemption is predicated in part on such Warrant Holder's representations set
forth herein. The Warrant Holder represents that it is experienced in evaluating
companies such as the Company, has such knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of its
investment and has the ability to suffer the total loss of the investment. The
Warrant Holder further represents that it has had the opportunity to ask
questions of and receive answers from the Company concerning the terms and
conditions of the Warrants, the business of the Company, and to obtain
additional information to such Warrant Holder's satisfaction.

                  g. ACCREDITED INVESTOR. The Warrant Holder is an "Accredited
Investor" within the meaning of Rule 501 of Regulation D under the Securities
Act, as presently in effect.

15.      AFFIRMATIVE COVENANTS.

         In addition to the following affirmative covenants, until the effective
date of an IPO, or earlier, as applicable, the Company hereby makes to Warrant
Holder the affirmative covenants made by the Company to the Purchasers in
Sections 8.1, 8.2, 8.3(a), 8.3(b) (beginning with the third quarter of the
fiscal year ending 1999) and 8.5 through 8.9 of the Stock Purchase Agreement. In
addition, the Company will provide Warrant Holder with reports each calendar
quarter during the term hereof regarding any changes in stock ownership in the
Company, including changes in shares, options, warrants or other equity
holdings.

                  a. BOARD REPRESENTATION. Promptly after the execution hereof,
the Company agrees to obtain an amendment to the Stockholders Agreement in form
and substance satisfactory to Warrant Holder, requiring that each Stockholder
(as therein defined) shall vote its Shares at any Stockholder's meeting called
for the purpose to elect directors to the Board of Directors and to take all
other actions necessary to ensure the election to the Board of Directors of one
(1) individual designated by Warrant Holder if the Company by the third
anniversary of the execution of this Warrant Agreement shall not have had
declared effective by the Securities and Exchange Commission an initial
registration statement covering the Common Stock and Warrant Holder owns Shares
equal to or exceeding 5% of the Fully Diluted Equity. The Company shall do
everything reasonably in its power to ensure that Warrant Holder is provided
with such representation on the Board of Directors including, without
limitation, including at least one (1) designee of Warrant Holder in any
nominees of the Board of Directors of the Company as Warrant Holder is entitled
to.

                  b. MFN STATUS. If the Company enters into any transaction with
another airline, hotel, rental car or other travel provider (the "Travel
Provider") with provisions, taken as a whole, which are more favorable to the
Travel Provider than the provisions available to Warrant Holder in the
transaction of which this Warrant Agreement is a part, then Warrant Holder shall
be


[**] = Confidential treatment requested for redacted portions.



                                       10

<PAGE>



entitled to the benefit of such more favorable provisions and the applicable
documents between Company and Warrant Holder shall be appropriately amended.
Provisions as used in this paragraph, include, without limitation, the
percentage of the equity of the Company which can be earned or acquired, the
method, rate and manner of earning equity or the right to acquire equity of the
Company including vesting and exercise price, antidilution adjustments,
covenants, board representation, registration rights, or the provisions of the
Airline Participation Agreement and side letter.

                  c. NO EQUITY PREFERENCE TO TRAVEL PROVIDERS. The Company will
not enter into any transaction with a Travel Provider in which the Company
issues, or agrees to issue, equity or rights to acquire equity where the
provisions in such transaction, including, without limitation, the percentage of
the equity of the Company which can be earned or acquired, the method, rate and
manner of earning equity or the right to acquire equity of the Company including
vesting and exercise price, antidilution adjustments, covenants, board
representation or registration rights, are more favorable to the Travel Provider
than the provisions available to Warrant Holder in the transaction of which this
Warrant Agreement is a part.

16.      MISCELLANEOUS.

                  a. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All of the
representations and warranties made (or confirmed) herein shall survive the
execution and delivery of this Agreement, any investigation by or on behalf of
the Warrant Holder or acceptance of the Warrants, until 60 days after receipt of
the Company's financial statements for the year ended December 31, 1999, and at
the end of such period, such representations and warranties and related
indemnification rights and obligations with respect thereto shall expire;
PROVIDED, HOWEVER, that the representations and warranties set forth in Sections
3.1, 3.2, 3.4, 3.7(a) and 3.9 of the Stock Purchase Agreement and confirmed
herein shall survive without any expiration and the representation and
warranties set forth in Section 3.12 of the Stock Purchase Agreement and
confirmed herein shall survive until the expiration of the applicable statute of
limitations.

                  b. NO CONSEQUENTIAL DAMAGES. No Party hereto shall be entitled
to consequential damages as a result of any breach of a covenant, representation
or warranty contained herein.

                     FORM OF PARTICIPATION WARRANT AGREEMENT
                       To Purchase Shares of Common Stock
                                   Dated as of

                           PRICELINE.COM INCORPORATED
                             a Delaware Corporation

                                                               Issue Date:

         THIS CERTIFIES THAT,              (the "Warrant Holder"), with a place
of business at                          , for value received, is entitled, upon
the terms and subject to the conditions of this Participation Warrant Agreement
(this "Warrant Agreement"), to subscribe for and purchase fully-paid and
non-assessable shares of common stock, par value $.01 per share (the "Common
Stock"), of Priceline.com Incorporated, a Delaware corporation (the "Company").

         1. ISSUANCE OF WARRANTS. On the Issue Date, the Company will issue to
the Warrant Holder warrants (the "Warrants") to acquire              ( ) shares
of the Common Stock (the "Shares").

         2. EXERCISE PRICE. The Warrants have an exercise price of $4.00 per
share of Common Stock, as adjusted pursuant to the provisions of Section 8 of
this Warrant Agreement (the "Exercise Price").

         3. TERM. Except as otherwise provided for herein, the term of the
Warrants and the right to purchase Shares as granted herein shall be
exercisable, at any time and from time to time, during the period commencing 210
days following the completion of an initial public offering of shares of Common
Stock of the Company pursuant to an effective Registration Statement under the
Securities Act of 1933, as amended (an "IPO"), and terminating at 5:00 p.m. New
York City local time on the third anniversary of the Issue Date (the Expiration
Date"), PROVIDED, HOWEVER, that if the Company has not completed an IPO on or
prior to such Expiration Date, then the term of the Warrants and the exercise
thereof shall be extended on a year to year basis thereafter until such time as
the Company has completed an IPO[: and provided further, that the Warrant Holder
shall have up to six months after completion of such IPO to exercise the
Warrants; and the term of the Warrants should be correspondingly extended if
necessary].

         4. EXERCISE OF PURCHASE RIGHTS.

                   (a) EXERCISE. The purchase rights represented by this Warrant
Agreement are exercisable by the Warrant Holder, in whole or in part, at any
time, or from time to time during the period set forth in Section 3 above, by
tendering to the Company at its principal office: a duly completed and executed
notice of exercise in the form attached hereto as EXHIBIT A (the "Notice of
Exercise"), the Warrants and the Exercise Price. Upon receipt of such items in
accordance with the terms set forth below, the Company shall issue to the
Warrant Holder a certificate for the number of shares of Common Stock purchased.
The Warrant Holder, upon exercise of the Warrants, shall be deemed to have
become the holder of the Shares represented thereby (and such Shares shall be
deemed to have been issued) immediately prior to the close of business on the
date or dates upon which the Warrants are exercised. In the event of any
exercise of the rights represented by the Warrants, certificates for the Shares
so purchased shall be delivered to the Warrant Holder or its designee as soon as
practical and in any event within ten (10) business days after receipt of such
notice and,




<PAGE>



unless the Warrants have been fully exercised or expired, new Warrants
representing the remaining portion of the Warrants and the underlying Shares, if
any, with respect to which this Warrant Agreement shall not then have been
exercised shall also be issued to the Warrant Holder as soon as possible and in
any event within such ten-day period.

                   (b) METHOD OF EXERCISE. The purchase rights hereby
represented may be exercised, at the election of the Warrant Holder, by the
tender of the Notice of Exercise and the surrender of the Warrants at the
principal office of the Company and by the payment to the Company, by check,
cancellation of indebtedness or other form of payment acceptable to the Company,
of an amount equal to the then applicable Exercise Price per share multiplied by
the number of Shares then being purchased.

                   (c) NET ISSUE EXERCISE. Notwithstanding any provisions herein
to the contrary, if the fair market value of one share of the Company's Common
Stock is greater than the Exercise Price (at the date of calculation as set
forth below), in lieu of exercising the Warrants for cash, the Warrant Holder
may elect to receive shares equal to the value (as determined below) of the
Warrants (or portion thereof being canceled) by surrender of the Warrants at the
principal office of the Company together with the duly executed Notice of
Exercise in which event the Company shall issue to the Warrant Holder a number
of shares of the Common Stock computed using the following formula:

                   X= Y (A-B)
                      -------
                         A

                   WHERE X= the number of shares of Common Stock to be issued to
                   the Warrant Holder;

                   Y= the number of shares of the Common Stock purchasable under
                   the warrants or, if only a portion of the Warrants is being
                   exercised, the portion of the Warrants being canceled (at the
                   date of such calculation);

                   A= the fair market value of one share of the Company's Common
                   Stock (at the date of such calculation); and

                   B= Exercise Price (at the date of such calculation).

For purposes of the above calculation, fair market value of one share of the
Common Stock shall be equal to the closing trading price of the Company's Common
Stock on the day immediately prior to the date the Notice of Exercise is
tendered to the Company.

         5. RESERVATION OF SHARES. The Company will at all times have authorized
and reserved a sufficient number of shares of Common Stock to provide for the
exercise of the rights to purchase the Shares as provided in this Warrant
Agreement. All of the Shares shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable, and free and
clear of all preemptive rights.

         6. NO FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant Holder's
rights to purchase the Shares.

         7. NO RIGHTS AS SHAREHOLDER. This Warrant Agreement does not entitle
the Warrant Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrant Holder's rights to purchase the
Shares as provided for herein.

         8. ADJUSTMENT RIGHTS. The Exercise Price and the number of shares of
Common Stock purchasable hereunder are subject to adjustment from time to time,
as follows:



                                        2

<PAGE>



                   (a) MERGER. If at any time there shall be a merger or
consolidation of the Company with or into another corporation when the Company
is not the surviving corporation, then, as part of such merger or consolidation,
lawful provision shall be made so that the holder of the Warrants evidenced
hereby shall thereafter be entitled to receive upon exercise of rights herein
granted, during the period specified herein and upon payment of the aggregate
Exercise Price, the number of shares of stock or other securities or property of
the successor corporation resulting from such merger or consolidation, to which
a holder of the stock deliverable upon exercise of the rights granted in this
Warrant Agreement would have been entitled in such merger or consolidation if
such rights had been exercised immediately before such merger or consolidation.
In any such case, appropriate adjustment shall be made in the application of the
provisions of this Warrant Agreement with respect to the rights and interests of
the holder after the merger or consolidation. The Company will not effect any
such merger or consolidation unless, prior to the consummation thereof, the
successor corporation shall assume, by written instrument reasonably
satisfactory in form and substance to the Warrant Holder, the obligations of the
Company under the Warrants[ and this Warrant Agreement].

                   (b) RECLASSIFICATION, ETC. If the Company at any time shall,
by subdivision, combination or reclassification of securities or otherwise,
change any of the securities as to which purchase rights under this Warrant
Agreement exist into the same or a different number of securities of any other
class or classes, this Warrant Agreement shall thereafter represent the right to
acquire such number and kind of securities as would have been issuable as the
result of such change with respect to the securities which were subject to the
purchase rights under this Warrant Agreement immediately prior to such
subdivision, combination, reclassification or other change.

                   (c) SPLIT, SUBDIVISION OR COMBINATION OF SHARES. If the
Company at any time shall split or subdivide its Common Stock, the Exercise
Price shall be proportionately decreased and the number of Shares issuable
pursuant to this Warrant Agreement shall be proportionately increased. If the
Company at any time shall combine or reverse split its Common Stock, the
Exercise Price shall be proportionately increased and the number of Shares
issuable pursuant to this Warrant Agreement shall be proportionately decreased.

                   (d) STOCK DIVIDENDS. If the Company at any time shall pay a
dividend payable in Common Stock, then the Exercise Price shall be adjusted,
from and after the date of determination of stockholders entitled to receive
such dividend, to that price determined by multiplying the Exercise Price in
effect immediately prior to such date of determination by a fraction (i) the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend and (ii) the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
after such dividend. The Warrant Holder shall thereafter be entitled to
purchase, at the Exercise Price resulting from such adjustment, the number of
shares of Common Stock (calculated to the nearest whole share) obtained by
multiplying (i) the Exercise Price in effect immediately prior to such
adjustment by (ii) the number of shares of Common Stock issuable upon the
exercise hereof immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

                   (e) ISSUE OF ADDITIONAL STOCK. For so long as the term of the
Warrants have not expired, upon each issuance or sale (or deemed issuance or
sale) by the Company of any additional shares of Common Stock (or securities
convertible or exercisable into Common Stock) which results or would have
resulted in a reduction in the Conversion Price of the Convertible Preferred (as
each such term is defined in the Company's Certificate of the Powers,
Designations, Preferences and Rights of the Series A Convertible Preferred Stock
(the "Certificate of Designation")) under Section 7(d)(ii) of the Company's
Certificate of Designation, then the Exercise Price in effect immediately prior
to each such issuance or sale shall, upon such issue or sale, be reduced by a
percentage equal to the same percentage that the applicable Conversion Price has
been reduced (or would have been reduced) as a result of such issuance or sale.

                   (f) OTHER CHANGES. If any change in the outstanding Common
Stock of the Company or any other event occurs as to which the other provisions
of this Section 8 are not strictly applicable or if


                                        3

<PAGE>



strictly applicable, would not fairly protect the purchase rights of the Warrant
Holder in accordance with such provisions, then the Board of Directors of the
Company shall make an adjustment in the number of and class of shares available
under the Warrants, the Exercise Price or the application of such provisions, so
as to protect such purchase rights as aforesaid. The adjustment shall be such as
will give the Warrant Holder upon exercise for the same aggregate Exercise Price
the total number, class and kind of shares as the Warrant Holder would have
owned had the Warrants been exercised prior to the event and had the Warrant
Holder continued to hold such shares until after the event requiring adjustment.

                   (g) NOTICE OF ADJUSTMENTS; NOTICES. Whenever the Exercise
Price or number of shares purchasable hereunder shall be adjusted pursuant to
Section 4 hereof, the Company shall issue a certificate signed by its Chief
Executive Officer or Chief Financial Officer setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated and the Exercise Price and number
of shares purchasable hereunder after giving effect to such adjustment, and
shall cause a copy of such certificate to be mailed (by first class mail,
postage prepaid) to the holder of this Warrant. The Company shall give written
notice to the Warrant Holder at least 10 [business] days prior to the date on
which the Company closes its books or takes a record for determining rights to
receive any dividends or distributions. The Company shall also give written
notice to the Warrant Holder at least 30 business days prior to the date on
which a merger or consolidation of the Company with or into another corporation
when the Company is not the surviving corporation shall take place.

                   (h) NO CHANGE OF WARRANT NECESSARY. Irrespective of any
adjustment in the Exercise Price or in the number or kind of securities issuable
upon exercise of the Warrant, unless the Warrant Holder otherwise requests, this
Warrant Agreement may continue to express the same price and number and kind of
shares of Common Stock as are stated in this Warrant Agreement as initially
executed.

         9. REDEMPTION. The Warrants represented by this Warrant Agreement are
not redeemable by the Company.

         10. COMPLIANCE WITH SECURITIES ACT; TRANSFERABILITY OF WARRANT OR
SHARES OF COMMON STOCK.

                   (a) COMPLIANCE WITH SECURITIES ACT. The Warrant Holder, by
acceptance hereof, agrees that the Warrants, and the shares of Common Stock to
be issued upon exercise of the Warrants, are being acquired for investment and
that such Warrant Holder will not offer, sell or otherwise dispose of the
Warrants, or any shares of Common Stock to be issued upon exercise of the
Warrants except under circumstances which will not result in a violation of the
Securities Act of 1933, as amended (the "Securities Act"), or any applicable
state securities laws. The Warrants and all shares of Common Stock issued upon
exercise of the Warrants (unless registered under) the Securities Act and any
applicable state securities laws) shall be stamped or imprinted with a legend in
substantially the following form:

                   "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
                   SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES
                   LAW. THEY MAY NOT BE SOLD OR OFFERED FOR SALE, PLEDGED,
                   HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF AN
                   EFFECTIVE REGISTRATION STATEMENT RELATED THERETO UNDER SAID
                   ACT AND APPLICABLE STATE SECURITIES LAWS OR UNLESS SUCH
                   REGISTRATION IS NOT REQUIRED TO EFFECTUATE SUCH TRANSACTION,
                   AND IF [REASONABLY] REQUESTED BY THE COMPANY, THE COMPANY HAS
                   RECEIVED AN OPINION OF COUNSEL TO THAT EFFECT."

                   (b) TRANSFER. Subject to the provisions of the Securities Act
and any applicable state securities laws, the Warrants and any related rights
hereunder may be sold, transferred, pledged or otherwise


                                        4

<PAGE>



disposed of (collectively, "Sold"), in whole or in part, to any person. Any
transfer or sale or attempted transfer or sale of this Warrant in violation of
any provision of this Warrant shall be void, and the Company shall not record
such transfer on its books or treat any purported transferee of the Warrant as
the owner of the Warrant for any purpose.

                   (c) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANTS. The
Warrants cannot be exchanged, transferred or assigned otherwise than in
accordance with the provisions of this Agreement. If the provisions of this
Agreement are complied with, upon surrender of the Warrants to the Company with
the Assignment Form annexed hereto as Exhibit B duly executed, and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant Agreement in the name of the heir, devisee or assignee
named in such instrument of assignment and this Warrant Agreement shall promptly
be canceled.

         11. RESTRICTED SECURITIES. The Warrant Holder understands that the
Warrants and the Shares issuable upon vesting and exercise of the Warrants, will
not be registered at the time of their issuance under the Securities Act for the
reason that the sale provided for in this Agreement is exempt pursuant to
Section 4(2) of the Securities Act based on the representations of the warrant
Holder set forth herein. The Warrant Holder represents that it is experienced in
evaluating companies such as the Company, has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment and has the ability to suffer the total loss of the
investment. The Warrant Holder further represents that it has had the
opportunity to ask questions of and receive answers from the Company concerning
the terms and conditions of the Warrants, the business of the Company, and to
obtain additional information to such Warrant Holder's satisfaction. The Warrant
Holder is an "Accredited Investor" within the meaning of Rule 501 of Regulation
D under the Securities Act, as presently in effect.

         12. REGISTRATION RIGHTS. [Within ninety (90) days of the date hereof,]
The Company will use its best efforts to cause the Warrant Holder to become a
party to that certain Amended Registration Rights Agreement, dated as of
December 8, 1998, by and among the Company and the stockholders of the Company
named therein[(the "Amended Registration Rights Agreement"), with the right to
demand registration of the Shares issuable upon vesting and exercise of the
Warrants], on such terms and conditions as may be reasonably acceptable to the
Company, the Warrant Holder and the other stockholders a party to such Amended
Registration Rights Agreement. [If the Company is unable to cause the Warrant
Holder to become a party to the Amended Registration Rights Agreement in
accordance with the immediately preceding sentence, the Company will, within 120
days after the date hereof, enter into a registration rights agreement (the
"Warrant Holder Registration Rights Agreement"), with the Warrant Holder on
substantially the same terms and conditions as apply to the "Demand
Stockholders" under the Amended Registration Rights Agreement (but excluding any
terms and conditions that are contrary to or in conflict with the terms of the
Amended Registration Rights Agreement). The inclusion of the Warrant Holder as a
party to the Amended Registration Rights Agreement or the entering into by the
Company of the Warrant Holder Registration Rights Agreement, in each case as
contemplated by this Section 12, will satisfy the Company's obligation under
this Section 12.]

         13. MISCELLANEOUS.

                   (a) NO CONSEQUENTIAL DAMAGES. No party hereto shall be
entitled to consequential damages as a result of any breach of a covenant,
representation or warranty contained herein.

                   (b) NOTICES. All notices, demands and other communications
provided for or permitted hereunder shall be made in writing and shall be by

                       (i) No failure or delay on the part of the Company, or 
the Warrant Holder in exercising any right, power or remedy hereunder shall 
operate as a waiver thereof, nor shall any single or partial exercise of any 
such right, power or remedy preclude any other or further exercise thereof or

purchase rights represented by this Warrant Agreement are exercisable by the
Warrant Holder, in whole or in part, at any time, or from time to time during
the period set forth in Section 3 above, by tendering to the Company at its
principal office: a duly completed and executed notice of exercise in the form
attached hereto as Exhibit A (the "Notice of Exercise"), the Warrants and the
Exercise Price. Upon receipt of such items in accordance with the terms set
forth below, the Company shall issue to the Warrant Holder a certificate for the
number of shares of Common Stock purchased. The Warrant Holder, upon exercise of
the Warrants, shall be deemed to have become the holder of the Shares
represented thereby (and such Shares shall be deemed to have been issued)
immediately prior to the close of business on the date or dates upon which the
Warrants are exercised. In the event of any exercise of the rights represented
by the Warrants, certificates for the Shares so purchased shall be delivered to
the Warrant Holder or its designee as soon as practical and in any event within
ten (10) business days after receipt of such notice and, unless the Warrants
have been fully exercised or expired, new Warrants representing the remaining
portion of the Warrants and the underlying Shares, if any, with respect to which
this Warrant Agreement shall not then have been exercised shall also be issued
to the Warrant Holder as soon as possible and in any event within such ten-day
period.

            (b) METHOD OF EXERCISE. The purchase rights hereby represented may
be exercised, at the election of the Warrant Holder, by the tender of the Notice
of Exercise and the surrender of the Warrants at the principal office of the
Company and by the payment to the Company, by check, cancellation of
indebtedness or other form of payment acceptable to the Company, of an amount
equal to the then applicable Exercise Price per share multiplied by the number
of Shares then being purchased.

            (d) NET ISSUE EXERCISE. Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Exercise Price (at the date of calculation as set forth below),
in lieu of exercising the Warrants for cash, the Warrant Holder may elect to
receive shares equal to the value (as determined below) of the Warrants (or
portion thereof being canceled) by surrender of the Warrants at the principal
office of the Company together with the duly executed Notice of Exercise in
which event the Company shall issue to the Warrant Holder a number of shares of
the Common Stock computed using the following formula:

             X= Y(A-B)
                ------
                  A

            WHERE X= the number of shares of Common Stock to be issued to the
            Warrant Holder;

            Y= the number of shares of the Common Stock purchasable under the
            warrants or, if only a portion of the Warrants is being exercised,
            the portion of the Warrants being canceled (at the date of such
            calculation);

            A= the fair market value of one share of the Company's Common Stock
            (at the date of such calculation); and

            B= Exercise Price (at the date of such calculation).

For purposes of the above calculation, fair market value of one share of the
Common Stock shall be equal to the closing trading price of the Company's Common
Stock on the day immediately prior to the date the Notice of Exercise is
tendered to the Company.

      5. RESERVATION OF SHARES. The Company will at all times have authorized
and reserved a sufficient number of shares of Common Stock to provide for the
exercise of the rights to purchase the Shares as provided in this Warrant
Agreement. All of the Shares shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and non-assessable, and free and
clear of all preemptive rights.


[**] = Confidential treatment requested for redacted portion.


                                  3

<PAGE>



      6. NO FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant Holder's
rights to purchase the Shares.

      7. NO RIGHTS AS SHAREHOLDER. This Warrant Agreement does not entitle the
Warrant Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrant Holder's rights to purchase the
Shares as provided for herein.

      8. ADJUSTMENT RIGHTS. The Exercise Price and the number of shares of
Common Stock purchasable hereunder are subject to adjustment from time to time,
as follows:

            (a) MERGER. If at any time there shall be a merger or consolidation
of the Company with or into another corporation when the Company is not the
surviving corporation, then, as part of such merger or consolidation, lawful
provision shall be made so that the holder of the Warrants evidenced hereby
shall thereafter be entitled to receive upon exercise of rights herein granted,
during the period specified herein and upon payment of the aggregate Exercise
Price, the number of shares of stock or other securities or property of the
successor corporation resulting from such merger or consolidation, to which a
holder of the stock deliverable upon exercise of the rights granted in this
Warrant Agreement would have been entitled in such merger or consolidation if
such rights had been exercised immediately before such merger or consolidation.
In any such case, appropriate adjustment shall be made in the application of the
provisions of this Warrant Agreement with respect to the rights and interests of
the holder after the merger or consolidation. The Company will not effect any
such merger or consolidation unless, prior to the consummation thereof, the
successor corporation shall assume, by written instrument reasonably
satisfactory in form and substance to the Warrant Holder, the obligations of the
Company under the Warrants.

            (b) RECLASSIFICATION, ETC. If the Company at any time shall, by
subdivision, combination or reclassification of securities or otherwise, change
any of the securities as to which purchase rights under this Warrant Agreement
exist into the same or a different number of securities of any other class or
classes, this Warrant Agreement shall thereafter represent the right to acquire
such number and kind of securities as would have been issuable as the result of
such change with respect to the securities which were subject to the purchase
rights under this Warrant Agreement immediately prior to such subdivision,
combination, reclassification or other change.

            (c) SPLIT, SUBDIVISION OR COMBINATION OF SHARES. If the Company at
any time shall split or subdivide its Common Stock, the Exercise Price shall be
proportionately decreased and the number of Shares issuable pursuant to this
Warrant Agreement shall be proportionately increased. If the Company at any time
shall combine or reverse split its Common Stock, the Exercise Price shall be
proportionately increased and the number of Shares issuable pursuant to this
Warrant Agreement shall be proportionately decreased.

            (d) STOCK DIVIDENDS. If the Company at any time shall pay a dividend
payable in Common Stock, then the Exercise Price shall be adjusted, from and
after the date of determination of stockholders entitled to receive such
dividend, to that price determined by multiplying the Exercise Price in effect
immediately prior to such date of determination by a fraction (i) the numerator
of which shall be the total number of shares of Common Stock outstanding
immediately prior to such

[**] = Confidential treatment requested for redacted portion.


                                  4

<PAGE>



dividend and (ii) the denominator of which shall be the total number of shares
of Common Stock outstanding immediately after such dividend. The Warrant Holder
shall thereafter be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of shares of Common Stock (calculated to the nearest
whole share) obtained by multiplying (i) the Exercise Price in effect
immediately prior to such adjustment by (ii) the number of shares of Common
Stock issuable upon the exercise hereof immediately prior to such adjustment and
dividing the product thereof by the Exercise Price resulting from such
adjustment.

            (e) ISSUE OF ADDITIONAL STOCK. For so long as the term of the
Warrants have not expired, upon each issuance or sale (or deemed issuance or
sale) by the Company of any additional shares of Common Stock (or securities
convertible or exercisable into Common Stock) which results or would have
resulted in a reduction in the Conversion Price of the Convertible Preferred (as
each such term is defined in the Company's Certificate of the Powers,
Designations, Preferences and Rights of the Series A Convertible Preferred Stock
(the "Certificate of Designation")) under Section 7(d)(ii) of the Company's
Certificate of Designation, then the Exercise Price in effect immediately prior
to each such issuance or sale shall, upon such issue or sale, be reduced by a
percentage equal to the same percentage that the applicable Conversion Price has
been reduced (or would have been reduced) as a result of such issuance or sale.

            (f) OTHER CHANGES. If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 8 are not strictly applicable or if strictly applicable, would not
fairly protect the purchase rights of the Warrant Holder in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number of and class of shares available under the Warrants, the Exercise
Price or the application of such provisions, so as to protect such purchase
rights as aforesaid. The adjustment shall be such as will give the Warrant
Holder upon exercise for the same aggregate Exercise Price the total number,
class and kind of shares as the Warrant Holder would have owned had the Warrants
been exercised prior to the event and had the Warrant Holder continued to hold
such shares until after the event requiring adjustment.

            (g) NOTICE OF ADJUSTMENTS; NOTICES. Whenever the Exercise Price or
number of shares purchasable hereunder shall be adjusted pursuant to Section 4
hereof, the Company shall issue a certificate signed by its Chief Executive
Officer or Chief Financial Officer setting forth, in reasonable detail, the
event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated and the Exercise Price and number of shares
purchasable hereunder after giving effect to such adjustment, and shall cause a
copy of such certificate to be mailed (by first class mail, postage prepaid) to
the holder of this Warrant. The Company shall give written notice to the Warrant
Holder at least 10 days prior to the date on which the Company closes its books
or takes a record for determining rights to receive any dividends or
distributions. The Company shall also give written notice to the Warrant Holder
at least 30 business days prior to the date on which a merger or consolidation
of the Company with or into another corporation when the Company is not the
surviving corporation shall take place.

            (h) NO CHANGE OF WARRANT NECESSARY. Irrespective of any adjustment
in the Exercise Price or in the number or kind of securities issuable upon
exercise of the Warrant, unless the

[**] = Confidential treatment requested for redacted portion.


                                  5

<PAGE>



Warrant Holder otherwise requests, this Warrant Agreement may continue to
express the same price and number and kind of shares of Common Stock as are
stated in this Warrant Agreement as initially executed.

      9. TERMINATION AND DAMAGES.

            (a) MATERIAL BREACH.

                  (i) In the event that the Warrant Holder is in breach of its
material obligations under this Warrant Agreement, and such breach is not cured
to the reasonable satisfaction of the Company within 30 days after delivering
notice of such breach to the Warrant Holder, the Company may terminate this
Warrant Agreement immediately and without further notice to the Warrant Holder.
Concurrent with any such termination by the Company, this Warrant Agreement, and
all unexercised Warrants issued hereunder, shall automatically terminate, be
canceled and of no further force and effect. In addition, upon any such
termination by the Company, the Warrant Holder shall pay the Company, as
liquidated damages for Warrant Holder's material breach of this Warrant
Agreement and not as a penalty, the sum of 1) $1,000,000, if such termination is
effected before December 31, 1999, or (2) $500,000, if such termination is
effected on or after December 31, 1999 and before December 31, 2000. Any such
payment shall be made in immediately available funds within thirty days from the
date of any termination of this Warrant Agreement by the Company permitted by
this Section 9(a).

                  (ii) In the event that the Company is in breach of its
material obligations under Section 4(c) of this Warrant Agreement, and such
breach is not cured to the reasonable satisfaction of the Warrant Holder within
thirty (30) days after delivering notice of such breach to the Company, the
Warrant Holder may thereupon terminate the parties rights and obligations under
Section 4(c) hereof; provided, that if the Company repeats a material breach
after notice and the Company's cure thereof, the cure period for such repeated
breach shall be five (5) days and provided further that upon the occurrence of
any second repeated breach, the Warrant Holder may immediately exercise its
termination rights hereunder. Upon any such termination, Warrant Holder shall
retain all of its rights under this Warrant Agreement with respect to its then
vested Warrants but all the then unvested warrants shall immediately terminate
and expire.

            (b) TERMINATION WITHOUT BREACH BY FEBRUARY 4, 1999. Either party may
terminate this Warrant Agreement, without cause, at anytime by written notice to
the other party received on or prior to February 4, 1999. In the event this
Warrant Agreement is terminated as contemplated by this Section 9(b), this
Warrant Agreement, and all Warrants issued hereunder, shall automatically
terminate, be canceled and of no further force and effect, and neither the
Warrant Holder nor the Company shall have any further obligation under any term
or provision of this Warrant Agreement.

            (c) TERMINATION WITHOUT BREACH AFTER FEBRUARY 4, 1999. Except as
otherwise provided in this Section 9(c), either party may terminate the parties'
rights and obligations under Section 4(c) hereof, without cause, at any time by
written notice to the other party; provided that (i) if Warrant Holder effects
such termination on or before December 31, 1999, all of the Warrants granted

[**] = Confidential treatment requested for redacted portion.


                                  6

<PAGE>



to Warrant Holder hereunder shall immediately terminate and expire and Warrant
Holder shall pay to the Company the liquidated damages prescribed in Section
9(a)(i)(1) hereof, and (ii) if Warrant Holder effects such termination after
December 31, 1999, but before December 31, 2000, the second traunch granted to
Warrant Holder shall immediately expire, and Warrant Holder shall pay to the
Company the liquidated damages prescribed in Section 9(a)(i)(2) hereof.
Notwithstanding any provision herein to contrary, Warrant Holder may not
exercise a termination under this Section 9(c) on or after December 31, 2000.

      10. REDEMPTION. Except as contemplated by Section 9 above, the Warrants
represented by this Warrant Agreement are not redeemable by the Company.

      11. COMPLIANCE WITH SECURITIES ACT; TRANSFERABILITY OF WARRANT OR SHARES
OF COMMON STOCK.

            (a) COMPLIANCE WITH SECURITIES ACT. The Warrant Holder, by
acceptance hereof, agrees that the Warrants, and the shares of Common Stock to
be issued upon exercise of the Warrants, are being acquired for investment and
that such Warrant Holder will not offer, sell or otherwise dispose of the
Warrants, or any shares of Common Stock to be issued upon exercise of the
Warrants except under circumstances which will not result in a violation of the
Securities Act of 1933, as amended (the "Securities Act"), or any applicable
state securities laws. The Warrants and all shares of Common Stock issued upon
exercise of the Warrants (unless registered under) the Securities Act and any
applicable state securities laws) shall be stamped or imprinted with a legend in
substantially the following form:

            "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
            OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAW. THEY MAY NOT BE
            SOLD OR OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE
            TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
            RELATED THERETO UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS
            OR UNLESS SUCH REGISTRATION IS NOT REQUIRED TO EFFECTUATE SUCH
            TRANSACTION, AND IF REQUESTED BY THE COMPANY, THE COMPANY HAS
            RECEIVED AN OPINION OF COUNSEL TO THAT EFFECT."

            (b) TRANSFER. Subject to the provisions of the Securities Act and
any applicable state securities laws, the Warrants and any related rights
hereunder may be sold, transferred, pledged or otherwise disposed of
(collectively, "Sold"), in whole or in part, to any person. Any transfer or sale
or attempted transfer or sale of this Warrant in violation of any provision of
this Warrant shall be void, and the Company shall not record such transfer on
its books or treat any purported transferee of the Warrant as the owner of the
Warrant for any purpose.

                                  7

<PAGE>



            (c) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANTS. The Warrants
cannot be exchanged, transferred or assigned otherwise than in accordance with
the provisions of this Agreement. If the provisions of this Agreement are
complied with, upon surrender of the Warrants to the Company with the Assignment
Form annexed hereto as Exhibit B duly executed, and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant Agreement in the name of the heir, devisee or assignee named in such
instrument of assignment and this Warrant Agreement shall promptly be canceled.

      12. RESTRICTED SECURITIES. The Warrant Holder understands that the
Warrants and the Shares issuable upon vesting and exercise of the Warrants, will
not be registered at the time of their issuance under the Securities Act for the
reason that the sale provided for in this Agreement is exempt pursuant to
Section 4(2) of the Securities Act based on the representations of the warrant
Holder set forth herein. The Warrant Holder represents that it is experienced in
evaluating companies such as the Company, has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment and has the ability to suffer the total loss of the
investment. The Warrant Holder further represents that it has had the
opportunity to ask questions of and receive answers from the Company concerning
the terms and conditions of the Warrants, the business of the Company, and to
obtain additional information to such Warrant Holder's satisfaction. The Warrant
Holder is an "Accredited Investor" within the meaning of Rule 501 of Regulation
D under the Securities Act, as presently in effect.

      13. REGISTRATION RIGHTS. The Company will use its best efforts to cause
the Warrant Holder to become a party to that certain Amended Registration Rights
Agreement, dated as of December 8, 1998, by and among the Company and the
stockholders of the Company named therein, on such terms and conditions as may
be reasonably acceptable to the Company, the Warrant Holder and the other
stockholders a party to such Amended Registration Rights Agreement. In the event
of the Company fails to have the Warrant Holder become a party to the Amended
Registration Rights Agreement on terms and conditions reasonably acceptable to
Warrant Holder by February 4, 1999, the Warrant Holder shall have the right to
terminate this Warrant Agreement by delivering a written notice to the Company
as prescribed in Section 9(b) hereof.

      14.   MISCELLANEOUS.

            (a) NO CONSEQUENTIAL DAMAGES. No party hereto shall be entitled to
consequential damages as a result of any breach of a covenant, representation
or warranty contained herein.

            (b) NOTICES. All notices, demands and other communications provided
for or permitted hereunder shall be made in writing and shall be by registered
or certified first-class mail, return receipt requested, telecopier, courier
service or personal delivery:

            (c) AMENDMENT AND WAIVER.

                  (i) No failure or delay on the part of the Company, or the
Warrant Holder in exercising any right, power or remedy hereunder shall operate

power or remedy preclude any other or further exercise

[**] = Confidential treatment requested for redacted portion.

<PAGE>



thereof or the exercise of any other right, power or remedy. The remedies
provided for herein are cumulative and are not exclusive of any remedies that
may be available to the Company and the Warrant Holder at law, in equity or
otherwise.

                  (ii) Any amendment, supplement or modification of or to any
provision of this Warrant Agreement, any waiver of any provision of this Warrant
Agreement, and any consent to any departure by the Company or the Warrant Holder
from the terms of any provision of this Agreement, shall be effective only if it

            (d) COUNTERPARTS. This Warrant Agreement may be executed in any

            (m) FURTHER ASSURANCES. Each of the parties shall execute such
