                               PROSPECTUS SUMMARY

    Priceline.com has pioneered a unique e-commerce pricing system known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price"--we collect consumer demand, in the form of
individual customer offers guaranteed by a credit card, for a particular product
or service at a price set by the customer. We then either communicate that
demand directly to participating sellers, or access participating sellers'
private databases to determine whether we can fulfill the customer's offer on
the basis of the pricing information and rules established by the sellers.
Consumers agree to hold their offers open for a specified period of time and,
once fulfilled, offers cannot be canceled. By requiring consumers to be flexible
with respect to brands, sellers and/or product features, we enable sellers to
generate incremental revenue without disrupting their existing distribution
channels or retail pricing structures.

    We commenced the priceline.com service on April 6, 1998 with the sale of
leisure airline tickets. Since that time, our business has grown significantly
and the priceline.com service now includes the following products and services:

    - leisure airline tickets, provided by six domestic and 16 international
      airline participants;

    - new automobiles, which was launched on a test basis in the New York
      metropolitan area in July 1998;

    - hotel room reservations, which was launched in October 1998, offers hotel
      rooms in substantially all major United States markets and includes as
      participants more than 10 leading national hotel chains; and

    - home financing services, which was launched in January 1999 with home
      mortgage services and now also includes home equity loans and refinancing
      services.

Through the innovative use of "adaptive marketing programs," we also market
customer acquisition programs for third parties. These programs facilitate the
completion of a higher percentage of successful transactions through the
priceline.com service while generating fee income for us.

    We generate revenues in a variety of ways depending on the product or
service sold. With respect to our airline ticket and hotel room reservation
services, we recognize as revenue the customer's named price, net of taxes, and
record as the cost of revenue the fare or rate charged by the seller. With
respect to our automobile service, we earn a fixed fee from both the customer
and the seller after the transaction is consummated. With respect to our home
financing service, we receive marketing fees equal to a percentage of the net
revenue generated by the service, which is operated in conjunction with
LendingTree, Inc. With respect to our adaptive marketing programs, we recognize
as revenue the fees due to us from our adaptive marketing partners.

    We believe that the priceline.com service already has achieved significant
consumer acceptance and widespread brand awareness. During the period from
launch through June 30, 1999, we collected guaranteed offers for approximately
5.1 million airline tickets, representing approximately $1.1 billion in total
consumer demand. This demand resulted in sales of approximately 762,000 airline
tickets, representing approximately $165.2 million in revenue. We intend to
continue to leverage the priceline.com brand by expanding our product offerings
to include other leisure travel products and other financial services products
and by expanding our new car sales service to the entire U.S. market. We also
are exploring expansion of our core "name your price" business model to other
areas of e-commerce, such as retail merchandise and the consumer-to-consumer
market.

FORWARD-LOOKING STATEMENTS."

OUR LIMITED OPERATING HISTORY MAKES EVALUATING OUR BUSINESS DIFFICULT

    Priceline.com was formed in July 1997 and began operations on April 6, 1998.
As a result, we have only a limited operating history on which you can base an
evaluation of our business and prospects. Our prospects must be considered in
the light of the risks, uncertainties, expenses and difficulties frequently
encountered by companies in their early stages of development, particularly
companies in new and rapidly evolving markets, such as online commerce, using
new and unproven business models. To address these risks and uncertainties, we
must, among other things:

    - attract leading sellers and consumers to the priceline.com service;

    - maintain and enhance our brand, and expand our product and service
      offerings;

    - attract, integrate, retain and motivate qualified personnel; and

    - adapt to meet changes in our markets and competitive developments.

We may not be successful in accomplishing these objectives.

WE ARE NOT PROFITABLE AND EXPECT TO CONTINUE TO INCUR LOSSES

    We have incurred net losses of $88.1 million during the period from July 18,
1997 (inception) through June 30, 1999, before giving effect to $68.6 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 $156.7 million for such period. We have not achieved profitability
and expect to continue to incur losses for at least the next two years. 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, hotel room reservations and related adaptive marketing programs. In order
to increase airline, hotel room 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 and hotel room reservations below
cost. In addition, as our business model evolves, we have introduced and expect
to continue 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 achieve
profitability.

                                       4
<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. Since
these fees historically have involved no direct costs, they have had a
disproportionately positive impact on our gross profit margins. A significant
reduction in consumer acceptance of our adaptive marketing programs, costs that
we may incur in connection with adaptive marketing programs, reductions in fees
paid to us in connection with such programs or any 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.

    During 1998 and the first two quarters of 1999, a substantial majority of
our adaptive marketing revenues were derived from fees paid by credit card
issuers for qualifying credit card applications submitted over the priceline.com
service in connection with customer offers for airline tickets. Through May 1,
1999, almost all of our adaptive marketing revenues were derived from fees
related to a credit card adaptive marketing program with Capital One Bank. In
May 1999, we replaced Capital One Bank with First USA Bank, a leading national
credit card issuer. Since that time, our credit card adaptive marketing program
revenues have been attributable to our adaptive marketing relationship with
First USA.

    Both the Capital One and First USA adaptive marketing programs enable our
customers to increase the amount of their offers by a specified amount by
applying online for a credit card. However, the fee structure of the First USA
program is based on different factors than the factors that were applicable
under the Capital One program. For example, under the Capital One program we
received fees based upon the submission of qualifying applications, while the
First USA program ties a portion of our fees to account activation and usage.
However, since the First USA program only recently commenced, we have no method
of accurately predicting such activation and usage rates. In addition, unlike
the Capital One program, a portion of the fees earned under the First USA
program is required to be reinvested in program incentives. Accordingly, the
First USA program may or may not generate revenues or gross profits comparable
to those previously generated under the Capital One program. The First USA
agreement has a term of five years, subject to certain earlier termination and
repricing rights of First USA. For example, subject to priceline.com's rights of
renegotiation, First USA has the right to terminate the agreement after one year
(and earlier under certain circumstances) if its financial returns under the
adaptive marketing program are not at least equivalent to certain agreed upon
levels. The full financial statement impact of the shift from the Capital One
adaptive marketing program to the First USA adaptive marketing program will not
be known until completion of future periods.

    In addition to our credit card adaptive marketing program with First USA, we
have an adaptive marketing program with E*TRADE for online brokerage services
and expect to commence adaptive marketing programs with Discover Financial
Services, Inc. for credit cards, Sprint Communications Company L.P. for long
distance telecommunications services and Earthlink Network, Inc. for the
provision of Internet services. Our adaptive marketing program with E*TRADE is
based on an oral agreement which may be terminated at any time and most of our
other adaptive marketing programs may be terminated on short notice.

    We cannot guarantee that any of our adaptive marketing programs will
continue beyond their initial terms or, even if continued, that they will be
successful. If they are not successful, our gross profit and results of
operations could be adversely affected.

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

                                       5
<PAGE>
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 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
represented approximately 83.7% of total revenue for the six months ended June
30, 1999. Leisure travel, including the sale of leisure airline tickets, is
dependent on personal discretionary spending levels. As a result, sales of
leisure airline tickets and other leisure travel products tend to decline during
general economic downturns and recessions. Unforeseen events, such as political
instability, regional hostilities, increases in fuel prices, travel-related
accidents and unusual weather patterns also may adversely affect the leisure
travel industry. As a result, our business also is likely to be affected by
those events. Significantly reducing our dependence on the airline and travel
industries is likely to take a long time and there can be no guarantee that we
will succeed in reducing that dependence.

    Sales of airline tickets from priceline.com's four largest airline
suppliers, exclusive of Continental Airlines, Inc., which joined the
priceline.com service in July 1999, accounted for approximately 92.0% of airline
ticket revenue for the six months ended June 30, 1999. As a result, currently we
are substantially dependent upon the continued participation of these four
airlines in the priceline.com service in order to maintain and continue to grow
our total airline ticket revenues. We currently have 22 participating airlines.
However, our airline participation agreements:

    - do not require the airlines to make tickets available for any particular
      routes;

    - do not require the airlines to provide any specific quantity of airline
      tickets;

    - do not require the airlines to provide particular prices or levels of
      discount;

    - do not require the airlines to deal exclusively with us in the public sale
      of discounted airline tickets; and

    - generally, can be terminated upon relatively short notice.

These agreements also outline the terms and conditions under which ticket
inventory provided by the airlines may be sold.

                                       6
<PAGE>
    Our agreement with Delta, subject to various exceptions, requires Delta's
approval of the addition of new carriers to the priceline.com service, restricts
the routes for which tickets may be offered by specified carriers through the
priceline.com service and imposes limitations on the code share arrangements of
specified carriers. Delta also may require the exclusion of specific markets in
order for certain other airlines to participate. These provisions could limit
our ability to expand our airline ticket service. In addition, our ability to
transfer or license our intellectual property to other travel providers is
limited in the manner set forth in the agreement.

    It is possible that, as the priceline.com service grows and becomes a
significant channel of distribution for airline tickets and as other carriers
seek participation in the priceline.com service, these competitively restrictive
provisions of the Delta agreement could raise issues under federal and state
antitrust laws. If that happened, either a federal or state government agency or
private party could initiate litigation seeking to enjoin us and Delta from
enforcing these provisions or seeking to collect treble damages. The outcome of
any such litigation would be uncertain. If, however, such a lawsuit resulted in
an injunction or subjected us to damages, our business and financial condition
could suffer.

    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.

    The sale of shares of common stock by the selling stockholders in this
offering is being made pursuant to the "piggyback" registration rights contained
in the registration rights agreement. Priceline.com obtained from parties to the
registration rights agreement that hold shares (or presently exercisable
warrants to purchase shares) of common stock available for sale in this offering
a waiver of a 30-day notice period under the agreement and a consent to the
assignment of registration rights by Messrs. Jay Walker and Richard Braddock,
each of whom chose to sell less than his pro rata number of shares in this
offering. Priceline.com did not obtain such waiver and consent from certain
other parties to the registration rights agreement (comprised of certain airline
participants) because they do not have shares (or presently exercisable warrants
to purchase shares) of common stock available for sale in this offering.
Priceline.com believes that no damages arise as a result of the failure to
obtain such waiver and consent since such airline participants do not have
shares (or presently exercisable warrants to purchase shares) of common stock
available for sale. Nevertheless, if a disagreement with such airline
participants were to arise, priceline.com can not be certain as to the effect,
if any, that it could have on its relationship with such airline participants or
whether damages or other remedies could be imposed.

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

                                       7
<PAGE>
designate the airline on which the customer purchases a ticket. In addition, a
breach of security on the Internet, even if we were not involved, could make
consumers unwilling to guarantee orders online with a credit card. Consequently,
it is possible that consumers and sellers will never utilize the priceline.com
service to the degree necessary for us to achieve profitability.

WE NEED TO SELL NEW PRODUCTS AND SERVICES

    We are unlikely to make significant profits unless we make new or
complementary products and services and a broader range of existing products and
services available through the priceline.com service. We will incur substantial
expenses and use significant resources in trying to expand the type and range of
the products and services that we offer. However, we may not be able to attract
sellers and other participants 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.

TWO NEW BUSINESSES WE ARE EVALUATING MAY NOT BE SUCCESSFUL

    In addition to broadening the products and services offered through the
priceline.com service, we may expand our current "name your price" business
model into other areas of e-commerce. We currently are evaluating the licensing
of our business model to two new companies. One of these companies is developing
a consumer-to-consumer business in which buyers would make conditional purchase
offers to acquire goods from other consumers. The other would enable consumers
to use the Internet to name the price that they are willing to pay for retail
merchandise, which they would pick up from participating retailers. However, we
have not determined the structure of our relationship with these companies,
which may include, among other things, our licensing of the priceline.com brand
and "name your price" business model and investment in such entities. These new
businesses may not be launched and, if launched, may not be successful. If these
new businesses are not favorably received by consumers, the association of our
brand name and business model with these new entities may adversely affect our
business and reputation and may dilute the value of our brand name. In addition,
to the extent that we may need to invest funds and/or management resources for
the development of these entities, our core business may suffer.

    Expansion of our core business model would expose us to additional risks not
currently applicable to our existing operations. For example, expansion into
retail products would give rise to operational challenges not applicable to our
existing products, such as consumer pick-up arrangements. Moreover, a
consumer-to-consumer service would create risks that we do not face currently,
such as deceptive or fraudulent activities conducted by users on the Web site.
The additional risks associated with an expansion of our core business could
have a material adverse effect on our business generally.

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

                                       8
<PAGE>
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 $34.9 million during the six months ended
June 30, 1999. 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. These individuals assigned all of their intellectual property
rights relating to the priceline.com service to Walker Digital's affiliate,
Walker Asset Management Limited Partnership. Walker Asset Management,
subsequently transferred the patent rights relating to the priceline.com service
and other related intellectual property rights to us. We, in turn, granted
Walker Digital a perpetual, non-exclusive, royalty-free right and license to use
certain intellectual property related to the priceline.com service for
non-commercial internal research and development purposes.

    Walker Digital also provides us with, among other things, a right to
purchase at fair market value any intellectual property that is in process or
has been fully developed and that is owned and subsequently acquired, developed
or discovered by Walker Digital or Walker Asset Management that will provide
significant value in the use or commercial exploitation of the initially
transferred patent and related intellectual property rights. Conflicts of
interest may arise from time to time between Walker Digital and us with respect
to the potential purchase by us of additional intellectual property rights at
fair market value and the pursuit of overlapping corporate opportunities.

    Walker Digital currently owns assets and intellectual property related to
two new areas of e-commerce into which we may expand our "name your price"
business model, one involving consumer-to-consumer sales and the other involving
the sale of retail merchandise. We may license our brand name and "name your
price" business model to two new companies formed to develop these businesses.
Walker Digital may contribute assets and intellectual property to these
companies in return for an equity interest in these companies.

    Walker Digital owns the intellectual property rights underlying the
technology associated with our adaptive marketing programs. Walker Digital has
licensed to priceline.com the right to use these intellectual property rights
under a perpetual, non-exclusive, royalty-free license agreement. Walker Digital
has pending several United States patent applications directed to different
aspects of the processes and technology supporting our adaptive marketing
programs.

                                       9
<PAGE>
    Walker Digital also provides us with various services, including (1)
research and development assistance; (2) patent planning, maintenance and
prosecution; and (3) other intellectual property services, including 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, for which
Priceline.com collects fees from Walker Digital. We also have guaranteed Walker
Digital's obligations under a lease whereby it leases office space that is used
by both companies.

    Certain of our executive officers and other key employees also are
directors, officers, employees or serve on advisory boards of Walker Digital and
either own, or hold an option to purchase, equity securities of Walker Digital.
Accordingly, because we have interlocking directors and officers and board level
advisors with Walker Digital, there may be inherent conflicts of interest
between Walker Digital and us. If a conflict arises between the management
decisions of priceline.com and Walker Digital, we could lose valuable management
input from our directors and officers who have conflicting obligations.

    Additionally, many of the options granted to employees and consultants of
priceline.com under our 1997 Omnibus Plan entitle holders of such options to
continue to vest options for the then current vesting period during which their
employment or consulting arrangement with priceline.com terminates if such
individuals continue to perform services, throughout the remainder of such
vesting period, for another entity controlled by Mr. Jay S. Walker.
Consequently, we could lose valuable personnel to an entity controlled by Mr.
Walker, while such personnel continue to vest options granted to them by
priceline.com for up to one vesting period.

    We have not adopted any formal plan or arrangement to address these
potential conflicts of interest with Walker Digital or other entities controlled
by Mr. Walker. We intend to review all related-party transactions and any
potential conflicts with Walker Digital and these other entities on a
case-by-case basis.

    Walker Digital owns directly approximately 5.2% of the outstanding common
stock of priceline.com. Additionally, Walker Digital has established an option
plan for its officers and employees that provides for the grant of options to
purchase priceline.com stock owned by Walker Digital.

    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. Mr. Walker also expects to
devote a considerable portion of his time developing and implementing the
consumer-to-consumer and retail merchandise Internet businesses. 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, and in July 1999, Mr. Daniel H. Schulman joined priceline.com
as our President and Chief Operating 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.

                                       10
<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 266 full-time
employees as of August 10, 1999. We also have employed many key personnel since
our launch in April 1998, including our Chairman and Chief Executive Officer and
our President and Chief Operating Officer, and a number of key managerial,
marketing, planning, financial, technical and operations personnel. 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. Publicity about a service
disruption also could cause a material decline in our stock price.

    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.

                                       11
<PAGE>
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
      financing services;

    - 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;

    - traditional travel agencies;

    - consolidators and wholesalers of airline tickets and other travel
      products, including online consolidators such as Cheaptickets.com;

    - 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 AutoNation, 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
      mortgage.com, Quicken Mortgage, E-Loan and iOwn, Inc.; 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 Amazon.com, 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. In addition, as we expand our business through the
introduction of new products and services, we will face competition from
established providers of these products and services. For example, if we expand
into the consumer-to-consumer market either directly or

                                       12
<PAGE>
through a licensing arrangement, we will face competition from established web
site operators such as eBay.

    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 issued United
States patent directed to methods and systems for generating airline-specified
time tickets. In addition, we have pending 25 United States and four
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;

    - newly discovered prior art could diminish the value of or invalidate an
      issued 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.

                                       13
<PAGE>
    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 Internet travel services that appear to use
customer-offer based transaction models, but based on the information we have
obtained to date, may not infringe our patent.

    Walker Digital currently owns assets and intellectual property related to
two new areas of e-commerce into which we may expand our "name your price"
business model, one involving consumer-to-consumer sales and the other involving
the sale of retail merchandise. We may license our brand name and "name your
price" business model to two new companies formed to develop these businesses.
Walker Digital may contribute assets and intellectual property to these
companies in return for an equity interest in these companies.

    Walker Digital owns the intellectual property rights underlying the
technology associated with our adaptive marketing programs. Walker Digital has
licensed to priceline.com the right to use these intellectual property rights
under a perpetual, non-exclusive, royalty-free license agreement. Walker Digital
has pending several United States patent applications directed to different
aspects of the processes and technology supporting adaptive marketing programs.

    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 recently received a notice from the United States Patent
and Trademark Office that an undisclosed patent applicant who we believe is
Woolston is seeking to provoke an interference on our core buyer-driven commerce
patent. We 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 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 announced in
February 1999 an agreement to license his issued patent and pending patent
applications to the owner of a competing Internet travel service.

    While the interference process is still at an early stage, we believe that
we have meritorious defenses to Woolston's claim, which we intend to pursue
vigorously. Among other things, we believe that the Woolston patent application
does not disclose the inventions covered by the priceline.com patent claims.

                                       14
<PAGE>
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 and pay damages from the date such patent issued at a cost which could
significantly adversely affect our business. If Woolston prevailed in both an
interference and an infringement action, then we could be enjoined from
conducting business through the priceline.com service to the extent covered by
the patent claims awarded to Woolston. In addition, defense of the interference
action may be expensive and may divert management attention away from our
business.

    TRADEMARKS, COPYRIGHTS AND TRADE SECRETS

    We regard the protection of our copyrights, service marks, trademarks, trade
dress and trade secrets as critical to our future success. We rely on a
combination of laws and contractual restrictions, such as confidentiality
agreements, to establish and protect our proprietary rights. However, laws and
contractual restrictions may not be sufficient to prevent misappropriation of
our technology or deter others from developing similar technologies. We also
attempt to register our trademarks and service marks in the United States and
internationally. However, effective trademark, service mark, copyright and trade
secret protection may not be obtainable and/or available in every country in
which our services are made available online.

    PENDING LITIGATION

    On January 19, 1999, a complaint was filed 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 us bearing interest at a rate of 6% per year and, in
connection with the loan, received warrants, which have subsequently been fully
exercised, to purchase 62,500 shares of our common stock. On February 22, 1999,
Marketel filed an amended complaint, and on March 17, 1999, Marketel filed a
second amended complaint. The second amended complaint includes as defendants,
Mr. Timothy G. Brier, our Executive Vice President, Travel, Mr. Bruce Schneier,
an individual and consultant to Walker Digital, and Mr. James Jorasch, an
individual and employee of Walker Digital, and 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 second amended complaint, Marketel
alleges, among other things, that the defendants conspired to misappropriate
Marketel's business model, which it describes as a buyer-driven electronic
marketplace for travel services and its appurtenant techniques, market research,
forms, plans and processes, and which an executive of Marketel allegedly
provided to Messrs. Walker and Jaeckle in confidence approximately ten years
ago. The second amended complaint also alleges that three former Marketel
employees are the actual sole inventors or co-inventors of priceline.com's core
buyer driven commerce patent (U.S. patent No. 5794207), which was issued on
August 11, 1998 with Messrs. Jay S. Walker, Bruce Schneier and James Jorasch
listed as the inventors and which patent was assigned to Walker Digital and
thereafter assigned to priceline.com. Marketel asks that the patent's
inventorship be corrected accordingly.

    Based upon publicly available information, we believe that Marketel's fax
and fee-based business was launched in 1991 and ceased operations seven months
later. Our Internet-based model was independently

                                       15
<PAGE>
developed at Walker Digital and priceline.com, and practiced by priceline.com
starting in 1998. Based on publicly available information and Marketel's second
amended complaint, we understand that Marketel operated a fax-based travel
information service which offered consumers, travel agents and/or consolidators
the opportunity to purchase specially printed forms. These forms, when
accompanied by an additional non-refundable fee, allowed prospective ticket
buyers to fax to Marketel credit-card guaranteed bids for airline travel at a
bid price specified by the buyer. We believe that Marketel has not engaged in
any regular commercial activities since ceasing operations in 1992. Based upon
publicly available information, Marketel reactivated its status as a corporation
by satisfying its back-due tax obligations to the State of California shortly
after the filing of the original complaint.

    On February 5, 1999, February 10, 1999 and March 31, 1999, the defendants
filed their answer, amended answer and answer to second amended complaint,
respectively, in which they denied the material allegations of liability in the
complaints. We and all other defendants strongly dispute the material legal and
factual allegations contained in Marketel's second amended complaint and believe
that the second amended complaint is without merit. We intend to defend
vigorously against the action. Since May 28, 1999, there has been a discovery
stay in effect, which was caused by the withdrawal of Marketel's counsel.
Marketel has retained new counsel, and we now anticipate moving forward with
discovery.

    Defending the Marketel litigation may involve significant expense and, due
to the inherent uncertainties of litigation, there can be no certainty as to the
ultimate outcome. Pursuant to the indemnification obligations contained in the
Purchase and Intercompany Services Agreement with Walker Digital, Walker Digital
has agreed to indemnify, defend and hold priceline.com harmless for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.

    DOMAIN NAMES

    We currently hold the Internet domain name "priceline.com," as well as
various other related names. Domain names generally are regulated by Internet
regulatory bodies. The regulation of domain names in the United States and in
foreign countries is subject to change. Regulatory bodies could establish
additional top-level domains, appoint additional domain name registrars or
modify the requirements for holding domain names. As a result, we may not
acquire or maintain the "priceline.com" domain name in all of the countries in
which we conduct business.

    The relationship between regulations governing domain names and laws
protecting trademarks and similar proprietary rights is unclear. Therefore, we
could be unable to prevent third parties from acquiring domain names that
infringe or otherwise decrease the value of our trademarks and other proprietary
rights.

    LICENSES

    In the future, we may license portions of our intellectual property,
including our issued patents, to third parties or to joint ventures or other
entities in which we may have an interest. 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

                                       16
<PAGE>
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 who historically
have purchased through traditional means of commerce, such as a travel agent for
airline tickets or a branch of a bank for home financings, 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 generally, as well as 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.

                                       17
<PAGE>
    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. Further, the costs related to Year 2000
compliance could be significant. Moreover, participating sellers in
priceline.com services could 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. However, we cannot guarantee that our security measures
will prevent security breaches. 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 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 HIGHLY VOLATILE

    The market price of our common stock is highly volatile and is likely to
continue to 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;

    - 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;

                                       18
<PAGE>
    - changes in the status of our intellectual property rights;

    - loss of a major adaptive marketing partner;

    - announcements by third parties of significant claims or proceedings
      against us or adverse developments in pending proceedings;

    - additions or departures of key personnel;

    - future sales of our common stock; and

    - stock market price and volume fluctuations.

    In addition, the trading prices of Internet stocks in general, including
ours, have experienced extreme price and volume fluctuations in recent months.
These fluctuations often have been unrelated or disproportionate to the
operating performance of these companies. The valuations of many Internet
stocks, including ours, are extremely high based on conventional valuation
standards, such as price to earnings and price to sales ratios. The trading
price of our common stock has increased significantly from the initial public
offering price. These trading prices and valuations may not be sustained. Any
negative change in the public's perception of the prospects of Internet or
e-commerce companies could depress our stock price regardless of our results.
Other broad market and industry factors may decrease the market price of our
common stock, regardless of our operating performance. Market fluctuations, as
well as general political and economic conditions, such as a recession or
interest rate or currency rate fluctuations, also may decrease the market price
of our common stock.

    In the past, securities class action litigation often has 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.

SUBSTANTIAL SALES OF COMMON STOCK ELIGIBLE FOR RESALE 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 our common stock by introducing a
large number of sellers to the market. Given the volatility that exists for our
shares, such sales could cause the market price of our common stock to decline.


    Upon completion of this offering, we will have outstanding 146,782,296
shares of common stock. Of these shares, the 5,500,000 shares of common stock
sold in this offering, the 10,000,000 shares of common stock in our initial
public offering and the 938,540 shares of common stock sold by employees upon
exercise of stock options pursuant to the option exercise program will be freely
tradeable without restriction under the Securities Act of 1933, as amended,
which is commonly referred to as the "Securities Act," unless purchased by
"affiliates" of priceline.com as defined in Rule 144 under the Securities Act.
The shares of common stock issuable upon conversion of the    % convertible
subordinated notes sold in the concurrent note offering will be freely tradeable
in a similar manner. In addition, 26,582,391 shares are issuable upon exercise
of outstanding options granted under the 1997 Omnibus Plan and the 1999 Omnibus
Plan. We have filed a registration statement on Form S-8 covering the shares of
common stock issuable upon exercise of such options. As a result, when the
options are exercised, the shares issued will be freely tradeable after
September 25, 1999 under the Securities Act unless purchased by "affiliates" of
priceline.com as defined in Rule 144 under the Securities Act. The balance of
our outstanding shares of common stock and the shares of common stock issuable
upon exercise of outstanding warrants will be "restricted securities" under the
Securities Act, subject to restrictions on the timing, manner and volume of
sales of these shares.



    Each of the selling stockholders and Mr. Jay S. Walker who, after this
offering, will own an aggregate of 147,835,331 shares of common stock, including
shares issuable upon exercise of options and warrants owned by them, have
agreed, subject to limited exceptions, for a period of 180 days after the date
of this


                                       19
<PAGE>

prospectus that they will not, without the prior written consent of Morgan
Stanley & Co. Incorporated, directly or indirectly, offer to sell, sell, pledge
or otherwise dispose of any shares of common stock. In addition, holders who
will own 3,547,311 shares of common stock after this offering and options to
purchase an additional 4,532,504 shares after this offering agreed in connection
with our initial public offering to similar restrictions until after September
25, 1999. In connection with our option exercise program, holders of options to
purchase 7,676,356 shares of common stock registered on our Form S-8 entered
into lock-up agreements restricting the exercise of their options and sale of
the underlying shares until 180 days after the date of this prospectus without
our prior written consent.



    After giving effect to these contractual restrictions, holding periods under
Rule 144 and shares that may be issued upon exercise of outstanding options and
warrants, we estimate that additional shares of common stock will be available
for sale in the public market as follows:

Since many of these shares were purchased at prices substantially below current
market prices, we believe a significant number of these shares will be sold when
eligible for resale.


    Upon consummation of this offering and subject to the foregoing lock-up
agreements, holders of up to 142,104,432 shares of common stock and securities
exercisable for shares of common stock will have various rights to request the
registration of their shares under the Securities Act. Of such shares,
approximately 10,010,000 shares are not subject to the 180-day lock-up relating
to this offering. "Demand" registration rights with respect to an aggregate of
approximately 5,190,000 shares could be exercised following expiration of the
initial public offering lock-up on September 25, 1999, excluding warrants to
purchase up to 1,125,000 shares which, by their terms, are not exercisable
during the 180-day lock-up period relating to this offering. In the event such a
demand is made, approximately 3,690,000 additional shares could be registered
pursuant to "piggy-back" registration rights. If such rights are exercised in
respect of shares that, at that time, are not available for sale publicly
pursuant to Rule 144, then such shares could be sold in the public market on
dates earlier than the dates as of which such shares are reflected as available
for sale in the table above. We believe holders of registration rights are
likely to exercise those rights as to some or all of their shares when they are
eligible to do so. Upon the effectiveness of such a registration, all shares
covered by such registration statement will be freely transferable.


    Walker Digital also owns directly approximately 5.2% of our outstanding
common stock. Walker Digital has established an option plan for its officers and
employees that provides for the grant of options to purchase common stock held
by Walker Digital.

    Future sales of our common stock, or the availability of our common stock
for sale, could adversely affect the market price for our common stock or our
ability to raise capital by offering equity securities.

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 products
and 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

                                       20
<PAGE>
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.com is
registered as a "seller of travel" under the California Seller of Travel Act and
is a member of the Airlines Reporting Corporation. In addition, a number of
state travel laws and regulations require compliance with specific disclosure,
bond and/or other requirements.

    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. With
the planned expansion of our new automobile service from the New York
metropolitan area to all 48 contiguous states, priceline.com will attempt to
register as an automobile broker/dealer in the jurisdictions where registration
is required, provided that it can reasonably comply with the requirements for
registration imposed by each jurisdiction. However, we may not be able to
register in all states. For example, we will not be able to register in a
jurisdiction that requires a dealer zoned lot or a franchise agreement with
manufacturers of the automobiles to be sold. We will work with the regulators of
the various jurisdictions where enforcement officials advise us that
registration is required to obtain waivers of such requirements, but we may not
be successful in our efforts.



    In jurisdictions where we cannot obtain registration, it is possible that
state regulatory bodies could take a strict enforcement position and we may be
unable to continue to make our new automobile services available in those
jurisdictions.


    HOME FINANCING SERVICES

    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 financing service in January 1999. LendingTree serves
as the back-end processing system, which presents offers we receive to multiple
mortgage lending institutions for consideration, for all of priceline.com's home
financing services. We provide and are responsible for maintaining the home
financing service on our Web site and develop and purchase all advertising.
LendingTree compensates us for the fair market value of our non-referral
services. We believe that offering the home financing 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 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 back-end processing system, which presents offers
we receive to multiple mortgage lending institutions for consideration, for the
home financing service on our Web site and is responsible for maintaining the
necessary and appropriate state registrations and licenses associated with
LendingTree's 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
financing service could be materially and adversely affected and we may be
unable to continue to make our home financing service available.

    We are exploring the possibility of acquiring a minority interest in, and
licensing the priceline.com name and business model to, a newly formed
subsidiary of a federally chartered savings and loan association. This entity
may be known as "priceline.mortgage.com" and also may serve as an entity that
could accept mortgage applications or mortgage qualification loans.

    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 also
are 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 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

    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

                                       22
<PAGE>
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. We recently met
with representatives of the Internal Revenue Service to informally discuss our
submission. We intend to revise and resubmit our request to address certain
factual and legal inquiries raised during our meeting. The actual ruling by the
Internal Revenue Service 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 $766,339 in additional taxes as of June 30, 1999. We
have accrued for such potential liability in our condensed balance sheet as of
June 30, 1999 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.

    STATE TAXES

    We file tax returns in such states as required by law based on principles
applicable to traditional businesses. In addition, we do not collect sales or
other similar taxes in respect of transactions conducted through the
priceline.com service (other than the federal air transportation tax referred to
above). However, one or more states could seek to impose additional income tax
obligations or sales tax collection obligations on out-of-state companies, such
as ours, which engage in or facilitate online commerce. A number of proposals
have been made at state and local levels that could impose such taxes on the
sale of products and services through the Internet or the income derived from
such sales. Such proposals, if adopted, could substantially impair the growth of
e-commerce and adversely affect our opportunity to become profitable.

    Legislation limiting the ability of the states to impose taxes on
Internet-based transactions recently has been enacted by the United States
Congress. However, this legislation, known as the Internet Tax Freedom Act,
imposes only a three-year moratorium, which commenced October 1, 1998 and ends
on October 21, 2001, on state and local taxes on (1) electronic commerce where
such taxes are discriminatory and (2) Internet access unless such taxes were
generally imposed and actually enforced prior to October 1, 1998. It is possible
that the tax moratorium could fail to be renewed prior to October 21, 2001.
Failure to renew this legislation would allow various states to impose taxes on
Internet-based commerce. The imposition of such taxes could adversely affect our
ability to become profitable.

    PAYROLL TAXES RELATED TO OPTION EXERCISES


    We currently have outstanding non-qualified stock options to purchase
26,582,391 shares issued to various employees, consultants and directors
pursuant to the 1997 Omnibus Plan and the 1999 Omnibus Plan. The options entitle
the holders to purchase common stock at a weighted average exercise price of
approximately $11.46 per share, subject to adjustment in accordance with the
1997 Omnibus Plan and the 1999 Omnibus Plan. Upon exercise of an option, we will
be required to make payments on behalf of the option holders for certain payroll
related taxes such as Social Security and Medicare. These payroll taxes will
appear as a general and administrative expense on our statement of operations
and will amount to approximately 1.5% to 2.0% of the difference between the
exercise price and the then fair market value of


                                       23
<PAGE>
the common stock at the time of exercise. However, upon exercise of outstanding
options, we will be paid the exercise price of the options that are exercised.
We also will be entitled to an income tax deduction equal to the sum of (1) the
difference between the exercise price of the option and the then fair market
value of the common stock at the time of exercise and (2) the total amount of
payroll related tax payments. As the calculation of this expense is directly
dependent upon our stock price and the exercise of options is in the sole
discretion of the holder of the options, the amount and timing of the expense
and the timing of the corresponding income tax deduction are not currently able
to be determined and are not within our control.

CONCENTRATED CONTROL COULD ADVERSELY AFFECT STOCKHOLDERS


    Upon consummation of this offering, Mr. Jay S. Walker, the Founder and Vice
Chairman of priceline.com, and Mr. Richard S. Braddock, Chief Executive Officer
of priceline.com, together with their respective affiliates (including, with
respect to Mr. Walker, Walker Digital) beneficially own approximately 42.4 and
12.0 percent, 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
our recent initial public offering, this offering and our concurrent offering of
convertible subordinated debt, 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 subordinated 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.

ANTI-TAKEOVER PROVISIONS AFFECTING US COULD PREVENT OR DELAY A CHANGE OF CONTROL

    Provisions of our certificate of incorporation and by-laws and provisions of
applicable Delaware law may discourage, delay or prevent a merger or other
change of control that a stockholder may consider favorable. Our board of
directors has the authority to issue up to 150,000,000 shares of preferred stock
par value $0.01 per share, of priceline.com and to determine the price and the
terms, including preferences and voting rights, of those shares without
stockholder approval. Although we have no current plans to issue additional
shares of our preferred stock, any such issuance could:

    - have the effect of delaying, deferring or preventing a change in control
      of our company;

    - discourage bids for our common stock at a premium over the market price;
      or

    - adversely affect the market price of, and the voting and other rights of
      the holders of, our common stock.

                                       24
<PAGE>
    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 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 our sale of 2,000,000 shares of common stock in this
offering are estimated to be approximately $133.3 million and the net proceeds
of our sale of   % convertible subordinated notes in the concurrent note
offering are estimated to be approximately $241.9 million, in each case, after
deducting underwriting discounts and commissions and estimated offering
expenses. Our management will retain broad discretion as to the allocation of
the proceeds of this offering and the concurrent note offering.


YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION


    Purchasers of common stock in this offering will suffer immediate and
substantial dilution. The dilution will be $67.96 per share in the net tangible
book value of the common stock from the assumed public offering price of $70.00
per share. As of August 10, 1999, there are (1) 26,582,391 shares of common
stock issuable upon exercise of options outstanding, with a weighted average
exercise price of approximately $11.46 per share, of which, 8,041,442 shares are
not vested; (2) 17,096,073 shares of common stock issuable upon exercise of
outstanding warrants at an exercise price of approximately $0.93 per share; (3)
937,500 shares of common stock issuable upon exercise of outstanding warrants at
an exercise price of $3.20 per share; (4) 1,250,000 shares of common stock
issuable upon exercise of warrants at an exercise price of $6.40 per share; and
(5) 1,000,000 shares of common stock issuable upon exercise of warrants at an
exercise price of $97.41 per share. However, none of the options issued or to be
issued pursuant to the 1997 Omnibus Plan or the 1999 Omnibus Plan may be
exercised until September 26, 1999. If such outstanding options and warrants to
purchase shares of common stock are exercised, there would be further dilution.

                                USE OF PROCEEDS


    Priceline.com will not receive any proceeds from the sale of shares of
common stock by the selling stockholders in this offering. The net proceeds to
priceline.com from the sale of the 2,000,000 shares of common stock offered by
it are estimated to be approximately $133.3 million, after deducting estimated
offering expenses of $1.5 million and the underwriting discounts and commissions
payable by priceline.com. The net proceeds to priceline.com from the sale of its
  % convertible subordinated notes in the concurrent note offering are estimated
to be approximately $241.9 million, after deducting estimated offering expenses
of $0.6 million and the underwriting discounts and commissions payable by
priceline.com. Priceline.com intends to use the net proceeds, over time, for
general corporate purposes, including working capital, funding of anticipated
operating losses, expenses associated with our advertising campaigns, brand-name
promotions and other marketing efforts, funding of product and service expansion
and capital expenditures. Priceline.com also could use a portion of the net
proceeds, currently intended for general corporate purposes, to invest in joint
ventures or other collaborative arrangements, or to invest in or acquire
businesses, technologies, products or services. In particular, a portion of the
proceeds may be used to make investments in and/or loans to two new business
entities with which priceline.com is exploring the possibility of licensing its
brand name and "name your price" business model.


    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."

                                    DILUTION


    The net tangible book value of priceline.com as of June 30, 1999 was $171.3
million, or $1.20 per share. Net tangible book value per share is determined by
dividing the 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 2,000,000 shares of common stock
offered hereby (after deducting the underwriting discounts and commissions and
estimated offering expenses), the adjusted net tangible book value of
priceline.com as of June 30, 1999 would have been approximately $297.9 million,
or $2.04 per share. This represents an immediate increase in net tangible book
value of $0.84 per share to existing stockholders and an immediate dilution of
$67.96 per share to new investors purchasing shares in this offering. 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
WITH THE FINANCIAL STATEMENTS AND RELATED NOTES THERETO INCLUDED ELSEWHERE IN
THIS PROSPECTUS.

OVERVIEW

    Priceline.com has pioneered a unique e-commerce pricing system known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price"--priceline.com collects consumer demand, in the
form of individual customer offers guaranteed by a credit card, for a particular
product or service at a price set by the customer. Priceline.com then either
communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether it can fulfill the
customer's offer on the basis of the pricing information and rules established
by the sellers. Consumers agree to hold their offers open for a specified period
of time and, once fulfilled, offers cannot be canceled. Priceline.com benefits
consumers by enabling them to save money, while at the same time benefitting
sellers by providing them with an effective revenue management tool capable of
identifying and capturing incremental revenues. By requiring consumers to be
flexible with respect to brands, sellers and product features, priceline.com
enables sellers to generate incremental revenue without disrupting their
existing distribution channels or retail pricing structures.

    Priceline.com was formed in July 1997 and its primary activities during the
period prior to launch consisted of recruiting and training employees,
developing its business model, implementing systems to support its business
model, developing relationships with seller participants and developing the
priceline.com brand. Priceline.com commenced operations in April 1998 with the
sale of leisure airline tickets. Since that time, priceline.com's business has
grown significantly and the priceline.com service now includes the following
products and services:

    - leisure airline tickets, provided by six domestic and 16 international
      airline participants;

    - new automobiles, which was launched on a test basis in the New York
      metropolitan area in July 1998;

    - hotel room reservations, which was launched in October 1998, offers hotel
      rooms in substantially all major United States markets and includes as
      participants more than 10 leading national hotel chains; and

    - home financing services, which was launched in January 1999 with home
      mortgage services and now also includes home equity loans and refinancing
      services.

Through the innovative use of "adaptive marketing programs," priceline.com also
markets customer acquisition programs for third parties. These programs
facilitate the completion of a higher percentage of successful transactions
through the priceline.com service while generating fee income for the company.
Priceline.com also is exploring expansion of its core "name your price" business
model to other areas of e-commerce, such as retail merchandise and the
consumer-to-consumer market.


    The number of full-time employees of priceline.com increased from 10 to 261
during the period from inception to June 30, 1999, and as of August 10, 1999,
priceline.com had 266 full-time employees.


    Priceline.com generates revenues in a variety of ways depending on the
product or service sold. With respect to its airline ticket and hotel room
reservation services, priceline.com recognizes as revenue the

                                       30
<PAGE>
customer's named price, net of taxes, and records as the cost of revenue the
fare or rate charged by the seller. With respect to its automobile service, it
earns a fixed fee from both the customer and the seller after the transaction is
consummated. With respect to its home financing service, it receives marketing
fees equal to a percentage of the net revenue generated by the service, 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.
Additionally, priceline.com generates revenues from third party sources,
including airline ticket processing fees from consumers and ancillary
reservation booking fees from the Worldspan reservation system for
priceline.com's booking of airline flight segments and hotel reservations
through the Worldspan system. Consumer fees are payable and recognized only upon
completion of successful transactions.

    All offers made through the priceline.com service are guaranteed by a
customer credit card and credit cards are the only form of payment accepted by
priceline.com. The manner in which and time at which revenues are recognized
differs depending on the product or service sold through the priceline.com
service. With respect to airline ticket and hotel room reservation services,
revenues are generated by transactions with customers who make offers to
purchase airline tickets and reserve hotel rooms supplied by participating
sellers. Revenues and related costs are recognized if, and when, priceline.com
accepts the customer's offer and charges the customer's credit card. Because
priceline.com is the merchant of record in these transactions, revenue for these
services includes the offer price paid by the customer, net of certain taxes and
fees. Airline and hotel revenues also may include fees from third parties for
adaptive marketing programs. With respect to automobile services, fees or other
payments payable by the seller and/or the customer are recognized as revenue.
With respect to home financing services, priceline.com receives no fees from
consumers. Priceline.com recognizes revenue from marketing fees paid directly by
LendingTree through the operation of its home financing services. Because
priceline.com acts as an intermediary between the customer and the seller in
auto and home financing transactions, revenues for these products and services
is recorded at the amount of the fee received, and not on the value of the
underlying transaction, when the transaction is completed. Automobile and home
financing services revenues also may include fees from third parties for
adaptive marketing programs.

    When making offers through the priceline.com service, consumers are
permitted to make only one offer within a seven day period unless they change
some feature of their itinerary, such as the date on which or the airport from
which they are willing to fly. In April 1999, priceline.com introduced a new
"checkstatus" feature on its Web site that invites consumers whose initial
requests are not satisfied to change a feature of their itinerary and resubmit
revised offers without having to start the offer submission process over again.
Commencing with the second quarter of 1999, priceline.com treats each initial
offer and any resubmitted offer made in response to the checkstatus invitation
as a single offer for purposes of measuring its offer fulfillment rates.

    During the period from launch through June 30, 1999, priceline.com collected
guaranteed offers for approximately 5.1 million airline tickets, representing
approximately $1.1 billion in total consumer demand. This demand resulted in
sales of approximately 762,000 airline tickets, representing approximately
$165.2 million in revenue.

    Because the priceline.com system does not set minimum offer thresholds, and
consumers are not charged to make offers for airline tickets and other products,
it is expected that priceline.com will receive a significant number of
unreasonable or fantasy offers. Accordingly, priceline.com also analyzes the
percentage of "reasonable" ticket requests that it is able to fill.
Priceline.com considers an offer for an airline ticket to be "reasonable" when
it is no more than 30% lower than the lowest generally available advance-
purchase fare for the same route. Using this standard, the overall percentage of
ticket requests considered reasonable for the six-month period ended June 30,
1999 was approximately 55.3%. The 626,860 tickets sold through priceline.com
during the six-month period represented approximately 34.7% of the combined
reasonable ticket requests for domestic and international flights. For domestic
routes where priceline.com's airline participants have strong coverage, that
percentage was higher, with approximately 40.0%

                                       31
<PAGE>
of all reasonable requests fulfilled for the same six-month period. The
percentage of reasonable offers that priceline.com is able to fill can also vary
depending on the particular route. The following table sets forth, for the
periods presented, data regarding the total percentage of "reasonable" ticket
requests fulfilled by priceline.com:

(1) For this period, due to the introduction of the new "checkstatus" feature,
    initial offers and any resubmitted offers made in response to this feature
    were treated as a single offer; comparisons with other periods may not be
    meaningful as resubmitted offers were considered separate offers in prior
    periods.

    Since its inception, priceline.com has incurred net losses in each fiscal
quarter. Priceline.com incurred net losses of $88.1 million during the period
from July 18, 1997 (inception) through June 30, 1999, before giving effect to
$68.6 million of non-cash charges arising from equity issuances to a number of
our participating airlines, its chief executive officer and other parties, as
more fully described below. As of June 30, 1999, priceline.com had an
accumulated deficit of $156.7 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 at least the next two years.
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."


    Priceline.com currently has outstanding non-qualified stock options to
purchase 26,582,391 shares issued to various employees, consultants and
directors pursuant to the 1997 Omnibus Plan and the 1999 Omnibus Plan. The
options entitle the holders to purchase common stock at a weighted average
exercise price of approximately $11.46 per share, subject to adjustment in
accordance with the 1997 Omnibus Plan and the 1999 Omnibus Plan. Upon exercise
of an option, priceline.com will be required to make payments on behalf of the
option holders for certain payroll related taxes such as Social Security and
Medicare. These payroll taxes will appear as a general and administrative
expense on priceline.com's statement of operations and will amount to
approximately 1.5% to 2.0% of the difference between the exercise price and the
then fair market value of the common stock at the time of exercise. However,
upon exercise of outstanding options, priceline.com will be paid the exercise
price of the options that are exercised. Priceline.com also will be entitled to
an income tax deduction equal to the sum of (1) the difference between the
exercise price of the option and the then fair market value of the common stock
at the time of exercise and (2) the total amount of payroll related tax
payments. As the calculation of this expense is directly dependent upon
priceline.com's stock price and the exercise of options is in the sole
discretion of the holder of the options, the amount and timing of the expense
and the timing of the corresponding income tax deduction are not currently able
to be determined and are not within priceline.com's control. Priceline.com
estimates that, in connection with the exercise of outstanding options pursuant
to the option exercise program, in the third quarter of 1999 it will (x) record
expenses of approximately $1.3 million in respect of such payroll related taxes;
(y) increase additional paid-in capital by approximately $944,000 in


                                       32
<PAGE>
respect of the exercise price of such options; and (z) increase common stock by
approximately $7,700 in respect of the par value of the shares purchased upon
exercise of such options.

    For the year ended December 31, 1998, priceline.com recorded aggregate
non-cash charges of $67.9 million. Of this amount, $6.5 million related to the
issuance of 8,125,000 shares of common stock to Mr. Richard S. Braddock, the
Chairman and Chief Executive Officer of priceline.com, and $61.1 million related
to the issuance of warrants to purchase 19,744,402 shares of common stock,
including warrants to purchase 19,556,902 shares of common stock issued to a
number of our participating airlines.

    In August 1998, priceline.com entered into a warrant agreement with Delta to
purchase up to 18,892,603 shares of common stock at an exercise price of
approximately $0.93 per share. Vesting was contingent upon achievement of
certain predetermined performance thresholds. However, there was no penalty for
failure to provide ticket inventory to satisfy these performance thresholds.
Accordingly, no expense was recorded when the warrant was issued. On December
31, 1998, priceline.com amended its agreement with Delta to eliminate the
vesting contingencies and fix the number of shares subject to the warrant at
18,619,402. The amended warrant issued to Delta will become exercisable at the
earlier of seven years or upon the achievement of certain performance
thresholds. However, the agreement does not require Delta to make any
performance commitments, is non-exclusive and allows Delta to participate in
other programs similar to the priceline.com service. Included in the non-cash
charges described above is approximately $58.7 million reflecting the fair value
of the Delta warrant on December 31, 1998.


    During July 1999, priceline.com issued to Continental Airlines a warrant to
purchase common stock that will become exercisable upon the earlier of July 2004
or upon the achievement of certain performance thresholds. However, the
agreement does not require Continental to make any performance commitments.
Accordingly, priceline.com will incur a non-cash charge of approximately $88.4
million during the quarter ending September 30, 1999 representing the fair value
of the warrant on the grant date.


    Priceline.com's travel agency license was previously held by Priceline
Travel, a separate company that was owned by Mr. Jay S. Walker, priceline.com's
Founder and Vice Chairman, and all of its airline ticket sales were effected
through Priceline Travel, which was merged with and into priceline.com as of
March 24, 1999. Accordingly, the financial statements of Priceline Travel as of
December 31, 1997 and December 31, 1998 (restated) and for the period July 18,
1997 (Inception) to December 31, 1997 and for the year ended December 31, 1998
(restated) are presented on a combined basis with priceline.com.

RESULTS OF OPERATIONS

    Priceline.com was formed in July 1997, but did not commence operations until
April 1998. Accordingly, comparisons with prior periods are not meaningful.

SIX MONTHS ENDED JUNE 30, 1999

    REVENUES

    Total revenues for the six months ended June 30, 1999 were $161.0 million.
Revenues for the period were comprised primarily of (1) transaction revenues
representing the selling price of airline tickets and hotel room reservations;
(2) fee income from adaptive marketing programs offered in connection with
priceline.com's product offerings; (3) ancillary revenues consisting of
Worldspan reservation booking fees and airline ticket processing fees; and (4)
fee income from priceline.com's home financing and auto programs.

    On April 23, 1999, the adaptive marketing program with Capital One ended and
priceline.com commenced its credit card adaptive marketing program with First
USA. The fee structure of the First USA program is based on different factors
and may or may not result in revenues comparable to those under the Capital One
program. For example, under the Capital One program priceline.com's fees were
based upon the submission of qualifying credit card applications, while the
First USA program ties a portion of

                                       33
<PAGE>
priceline.com's fees to account activation and usage. Because, to date, there is
no meaningful activation and usage experience upon which to draw, priceline.com
cannot predict the degree to which revenues ultimately will be recognized under
the First USA program. In addition, priceline.com expects that future
contributions to adaptive marketing revenues from credit card adaptive marketing
programs may decline on a percentage basis, as agreements with new adaptive
marketing suppliers are reached and become operative. At the same time,
increased transaction activity, particularly associated with airline ticket
sales and related processing fees, is likely to provide an increasing portion of
revenues. All of these factors are likely to diminish the proportion of
priceline.com's revenues provided by its credit card adaptive marketing
programs.

    During the six months ended June 30, 1999, priceline.com also earned revenue
from its Customer Affinity Share Purchase Program, the first phase of its
adaptive marketing program with E*TRADE. Revenues from this program related
specifically to the referral of priceline.com customers to E*TRADE in connection
with priceline.com's initial public offering and, therefore, are not recurring.
Priceline.com also commenced the second phase of its adaptive marketing program
with E*TRADE under which E*TRADE compensates priceline.com for offering
priceline.com customers the opportunity to open an account with E*TRADE while
visiting or making an offer on the priceline.com Web site. Priceline.com intends
to continue to add adaptive marketing programs so that consumers have a variety
of programs from which to choose and priceline.com has a diversified source of
adaptive marketing revenues. See "Risk Factors--We are Dependent on Adaptive
Marketing Programs."

    Priceline.com's ancillary revenues for the six month period increased as a
result of volume driven increases in Worldspan reservation booking fees and a
recently introduced processing fee. Revenues from these sources are linked to
airline ticket sales and, accordingly, will increase or decrease in future
periods in relation to changes in the volume of airline ticket sales. Worldspan
reservation booking fees also are linked to hotel reservations booked through
the Worldspan system.

    COST OF REVENUES AND GROSS PROFIT

    Cost of revenues for the six months ended June 30, 1999 totaled $145.1
million, consisting of product costs of $144.3 million and supplier warrant
costs of $761,518. Product costs were comprised of 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. Product costs also included the cost of hotel rooms from
priceline.com's suppliers, net of hotel tax. Supplier warrant costs represent a
non-cash expense related to the issuance of common stock warrants to one of
priceline.com's airline program participants in January 1999. Priceline.com
anticipates that it will recognize additional supplier warrant costs in the
amount of approximately $381,000 in each of the next six fiscal quarters.

    Gross profit, which is comprised of revenues less cost of revenues, was
$15.9 million for the six months ended June 30, 1999. Gross margin was 9.9% for
the period. Excluding the effect of non-cash supplier warrant costs,
priceline.com would have had gross profit of $16.7 million and gross margin of
10.3% for the six months ended June 30, 1999. Gross profit and gross margin are
affected by the price at which priceline.com causes offers to be fulfilled and
by the level of fees generated by adaptive marketing programs. Priceline.com is
able to manage the level of gross margins by controlling the price at which it
will cause offers to be fulfilled. During the first quarter of 1999,
priceline.com chose 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. As a result of the
growth of the priceline.com service, priceline.com reduced the percentage of
airline tickets that it chose to sell below cost during the second quarter,
thereby improving gross margins on airline ticket sales. Because the fees
generated by adaptive marketing revenue and ancillary revenues did not involve
separate costs, adaptive marketing revenues and ancillary revenues had a
disproportionately positive impact on total gross margins and made a very
substantial contribution to priceline.com's gross profit for the six months
ended June 30,

                                       34
<PAGE>
1999. If our transaction activity continues to grow, priceline.com expects the
proportion of its gross profit and gross margin attributable to adaptive
marketing revenues to decline.

    Gross margins for the six months ended June 30, 1999 also were affected by a
somewhat lower gross margin in the second quarter of 1999 compared to the first
quarter of 1999. See "Quarterly Results of Operations" below. Gross margins for
the second quarter of 1999 were affected by a change in revenue mix, resulting
from a greater percentage of revenues being attributable to transaction revenues
rather than fee based revenues. Fee-based revenues, such as adaptive marketing
revenues, ancillary revenues and revenues from financial services and
automobiles, have higher margins than transaction revenues, which are derived
from the spread between customer offers and the product costs.

    OPERATING EXPENSES

    SALES AND MARKETING.  Sales and marketing expenses for the six months ended
June 30, 1999 totaled $34.9 million, or 21.7% of revenues. Approximately 65.0%
of sales and marketing expenses were comprised of advertising and promotion
expenses. The remaining expenses consisted primarily of (1) fees payable to a
third party service provider that operates priceline.com's call center; (2)
credit card processing fees; (3) provisions for customer credit card
charge-backs (based upon a percentage reflecting priceline.com's historical
experience); and (4) compensation for priceline.com's sales and marketing
personnel.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses for the six
months ended June 30, 1999 totaled $9.2 million, or 5.7% of revenues. General
and administrative expenses for the period were comprised primarily of
compensation for personnel, fees for outside professionals, telecommunications
and other overhead costs, including occupancy expense.

    SYSTEMS AND BUSINESS DEVELOPMENT.  Systems and business development expenses
for the six months ended June 30, 1999 totaled $5.7 million, or 3.5% of
revenues. Systems and business development expenses for the period were
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.

    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 requires capitalization of
certain costs of computer software developed or obtained for internal use.
Priceline.com adopted this SOP on January 1, 1999 and, during the six-month
period ended June 30, 1999, priceline.com capitalized approximately $5.7 million
of computer software developed or obtained for internal use. Amortization of
such costs aggregated approximately $149,000 during the six month period ended
June 30, 1999.

    INTEREST INCOME, NET

    Interest income, net for the six months ended June 30, 1999 totaled $2.4
million, reflecting approximately $2.5 million of interest income earned by
priceline.com on its cash balances, net of interest expense for the period. Cash
balances increased during this period due to priceline.com's initial public
offering in April 1999.

SIX MONTHS ENDED JUNE 30, 1998

    Priceline.com commenced its service on April 6, 1998 with the sale of
leisure airline tickets. Revenues from the sale of airline tickets during the
six month period ended June 30, 1998 were $7.0 million. Cost of revenues during
this period exceeded such revenues by approximately $900,000. Priceline.com
chose to sell a substantial number of leisure airline tickets below its cost
during this period in order to increase airline revenues, build a record of
successful transactions and enhance the priceline.com brand.

                                       35
<PAGE>

    In addition, priceline.com incurred operating expenses of $17.9 million,
consisting of sales and marketing expenses of $7.8 million, general and
administrative expenses of $4.8 million and systems and business development
expenses of $5.4 million. These activities resulted in an operating loss of
$18.9 million and, after consideration of interest income, a net loss of $18.7
million for the six month period ended June 30, 1998.


YEAR ENDED DECEMBER 31, 1998

    RESTATEMENT

    Subsequent to the issuance of priceline.com's combined 1998 financial
statements, priceline.com's management determined that the calculation of the
fair value of the Delta warrant, other airline warrants and the beneficial
conversion feature on the Series B preferred stock should be revised. The fair
value of the Delta warrant and the other airline warrants has been revised to
reflect the change in the volatility assumption from 50% to 132%, eliminate the
"large block" and lack of marketability discounts, and consider the warrant's
anti-dilution and exercisability features. As a result, the 1998 combined
financial statements have been restated from the amounts previously reported to
recognize an additional $22.0 million of expense based upon the revised fair
value of the warrants at December 31, 1998, of which $3.0 million is included in
the cost of revenues-supplier warrant costs and $19.0 million is included in
expenses-supplier start-up warrant costs. In addition, the value of the
beneficial conversion feature on the Series B preferred stock has been revised
to calculate such amount based on 22,500,000 shares. As a result, additional
paid-in capital and accumulated deficit have been restated from amounts
previously reported to recognize an additional $883,424 of accretion of
preferred stock based on the revalued beneficial conversion feature.

    A summary of the significant effects of the restatement is as follows:

(1) Per share basic and diluted loss applicable to common stockholders as
    previously reported has been restated for a 1.25 for one stock split.

    REVENUES

    Total revenues for the year ended December 31, 1998 were $35.2 million.
Since commencement of operations in April 1998, essentially all revenues
consisted of airline ticket sales, hotel room reservations and related adaptive
marketing programs. Approximately $4.0 million of total revenues were
attributable to adaptive marketing programs, all of which were attributable to
priceline.com's third-party credit card marketing program with Capital One Bank.
See "--Cost of Revenues and Gross Profit (Loss)." Priceline.com's automobile
sales service, which was launched on a test basis in the New York metropolitan
area in July 1998, did not contribute materially to revenues during the period.

                                       36
<PAGE>
    COST OF REVENUES AND GROSS PROFIT (LOSS)

    Cost of revenues for the year ended December 31, 1998 totaled $36.5 million,
consisting of product costs of $33.5 million and supplier warrant costs of $3.0
million. Product costs represent the cost of airline tickets from
priceline.com's suppliers, net of the federal air transportation tax, segment
fees and passenger facility charges imposed in connection with the sale of
airline tickets. Supplier warrant costs represent a non-cash expense related to
the pro-rata amount of the Delta warrant earned prior to December 31, 1998, the
date on which the Delta warrant was amended. Priceline.com anticipates that it
will recognize additional supplier warrant costs in the amount of $1.6 million
in each of 1999 and 2000 in connection with additional warrants issued to a
participating airline in January 1999.

    Gross profit (loss), which is comprised of revenues less cost of revenues,
was $(1.3) million for the year ended December 31, 1998. Excluding the effect of
the non-cash supplier warrant costs, priceline.com would have had gross profit
of $1.7 million for the year ended December 31, 1998. Priceline.com is able to
manage the level of gross margins by controlling the price at which it will
cause offers to be fulfilled. Priceline.com has chosen to sell a substantial
number of tickets below its cost in order to increase airline and adaptive
marketing revenues, build a record of successful transactions, and enhance the
priceline.com brand. Because the fees generated by adaptive marketing programs
have historically involved no separate costs, adaptive marketing revenues have
had a disproportionately positive impact on priceline.com's total gross margin.
The Capital One adaptive marketing program accounted for all of priceline.com's
adaptive marketing revenues in 1998.

    OPERATING EXPENSES

    SUPPLIER START-UP WARRANT COSTS.  Supplier start up warrant costs for the
year ended December 31, 1998 totaled $58.0 million, or 164.5% of revenues.
Supplier start up warrant costs consist of a non-cash charge representing the
fair value of warrants issued to certain participating airlines in the
priceline.com service in connection with securing priceline.com's relationship
with those airlines.

    SALES AND MARKETING.  Sales and marketing expenses for the year ended
December 31, 1998 totaled $24.4 million, or 69.2% of revenues. Approximately 50%
of sales and marketing expenses were comprised of radio and newspaper
advertising expenses. The balance was comprised of (1) fees payable to a third
party service provider, which operates priceline.com's call center, (2) credit
card processing fees, (3) provisions for customer credit card charge-backs
(based upon a percentage reflecting priceline.com's historical experience), and
(4) compensation for priceline.com's sales and marketing personnel.

    SYSTEMS AND BUSINESS DEVELOPMENT.  Systems and business development expenses
for the year ended December 31, 1998 totaled $11.1 million, or 31.6% of
revenues. Systems and business development expenses are comprised primarily of
compensation to priceline.com's information technology and product development
staff and payments to outside contractors, data communications and other
expenses associated with operating priceline.com's Web site and, to a lesser
extent, depreciation on computer hardware and licensing fees for computer
software.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses for the
year ended December 31, 1998 totaled $18.0 million or 51.1% of revenues. General
and administrative expenses consist primarily of compensation for personnel,
fees for outside professionals, telecommunications and other overhead costs,
including occupancy expense. Also included is a one-time non-cash charge of $6.5
million relating to the issuance to Mr. Richard S. Braddock of a profits
interest with respect to 6.5 million units in priceline.com's predecessor,
priceline.com LLC. These units were granted to Mr. Braddock in connection with
his employment by priceline.com, and were subsequently converted into 8,125,000
shares of common stock.

    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.

- ------------------------

*   Adjusted Gross Profit and Adjusted Gross Margin reflect the elimination of
    non-cash charges associated with the supplier warrants.

    Revenues increased in each quarter since the commencement of operations in
April 1998. The increase in each quarter is due primarily to an increase in
airline ticket sales resulting from expanded inventory, improved fill rates and
an expanded customer base due to increased market awareness and acceptance of
the priceline.com service. In addition to the foregoing, (1) the increase in
revenue in the fourth quarter of 1998 is due to the addition of a significant
new airline partner and the inclusion for a full quarter of priceline.com's
Capital One adaptive marketing program, as well as, to a lesser extent, the
introduction of priceline.com's hotel room reservation service in October 1998;
and (2) the increase in revenue in the first and second quarters of 1999 is due
to increased customer offers, an increased supply of airline seats from our
existing airline partners and, to a lesser extent, the national launch of our
hotel room reservation service in March 1999.

    Cost of revenues, which consists of product costs and supplier warrant
costs, increased in each quarter of 1998 and the first and second quarters of
1999. Product costs, which are associated primarily with the amounts paid to
priceline.com's airline partners for airline tickets, net of federal air
transportation tax,

                                       38
<PAGE>
segment fees and passenger facility charges imposed in connection with the sale
of airline tickets, also increased each quarter in conjunction with increases in
total revenue. Supplier warrant costs consist of a non-cash expense related to
the pro-rata amount of the Delta warrant earned prior to December 31, 1998, the
date on which the Delta warrant agreement was amended. Excluding the effect of
the non-cash supplier warrant costs, priceline.com's gross profit would have
increased every quarter from the quarter ended June 30, 1998 to the quarter
ended June 30, 1999. The decreases in adjusted gross margins for the quarters
ended March 31, 1999 and June 30, 1999 were primarily due to the more rapid
growth of transaction-based revenues compared to fee-based revenues during those
periods. As a result of the differences in growth rates, our revenue mix changed
compared to prior periods with a greater percentage of revenues being
attributable to transaction revenues rather than fee-based revenues. Fee-based
revenues, such as adaptive marketing revenues, ancillary revenues and revenues
from financial services and automobiles, have higher margins than transaction
revenues, which are derived from the spread between customer offers and the
product costs.

    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 exercise of employee stock options that give rise to social security
      and medicare payroll taxes;

    - 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

                                       39
<PAGE>
planned expenditures would have an immediate adverse effect on its business,
results of operations and financial condition.

    Priceline.com's limited operating history and rapid growth makes it
difficult for it to assess the impact of seasonal factors on its business.
Nevertheless, priceline.com expects its business to be subject to seasonal
fluctuations, reflecting a combination of seasonality trends for the products
and services offered by the 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 June 30, 1999 totaled approximately $246.6 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. On
April 1, 1999, priceline.com completed its initial public offering in which it
sold 10,000,000 shares of its common stock at a price of $16.00 per share,
raising $160.0 million in gross proceeds. Offering proceeds to priceline.com,
net of approximately $11.2 million in aggregate underwriters discounts and
commissions and $4.4 million in related expenses, were approximately $144.4
million. As of June 30, 1999, priceline.com had approximately $142.8 million in
cash and cash equivalents.

    In April 1998, priceline.com received proceeds from a loan of $1.0 million
for working capital from a high net worth individual who also was issued a
warrant to purchase 62,500 shares of common stock at an exercise price of $0.80
per share. This loan expires on April 15, 2003 and bears interest at a rate of
6.0%. The related warrant has been fully exercised, and as of the date of this
prospectus, the loan has been repaid.

    In April 1999, priceline.com made a $3.3 million loan to Mr. Richard S.
Braddock for the payment of taxes related to the issuance to Mr. Braddock of
8,125,000 shares of common stock in August 1998. The loan bears interest at
5.28% per annum. Interest is payable annually and principal is payable in
January 2004.

                                       40
<PAGE>
    In July 1999, priceline.com made a $6.0 million loan to Mr. Daniel H.
Schulman, pursuant to the terms of his employment agreement dated June 14, 1999.
The loan bears interest annually at 5.82% per annum. Subject to prepayment
obligations and to forgiveness in the event of certain changes of control,
death, or termination without cause, pursuant to the terms of the loan, accrued
interest and principal are payable in July 2004.

    Concurrent with this offering, priceline.com is making an offering of $250.0
million aggregate principal amount of   % convertible subordinated notes due
2006, which will be convertible into shares of priceline.com common stock at a
conversion price of $    per share, subject to adjustment. Priceline.com expects
the proceeds from the concurrent note offering (after deducting the estimated
offering expenses and net of underwriting discounts and commissions), to be
approximately $241.9 million.

    Net cash used in operating activities was $33.8 million for the six months
ended June 30, 1999. Net cash used in operating activities was primarily
attributable to net losses.

    Net cash used in investing activities was $20.6 million for the six months
ended June 30, 1999. Net cash used in investing activities was primarily related
to purchases of property and equipment.

    Net cash provided by financing activities was $143.6 million for the six
months ended June 30, 1999. Net cash provided by financing activities resulted
primarily from priceline.com's initial public offering of 10,000,000 shares of
its common stock, for which priceline.com received approximately $149.0 million
in cash, net of underwriting discounts and commissions on April 1, 1999.

    Priceline.com had commitments for capital expenditures as of June 30, 1999
of approximately $1.2 million. Capital expenditures were $11.3 million for the
six months ended June 30, 1999, and priceline.com expects such expenditures to
be at least $22.0 million for the full year of 1999. As a result of its rapid
growth, priceline.com expects to increase capital expenditures for purchased
software, internally developed software, computer equipment and leasehold
improvements.

    Priceline.com believes that, based upon its current operating plan, its
existing cash and cash equivalents, the net proceeds from its initial public
offering, the net proceeds from this offering and its concurrent note offering
and any cash generated from operations will be sufficient to fund its operating
activities, capital expenditures and other obligations through at least the next
three years. However, if during that period or thereafter priceline.com is not
successful in generating sufficient cash flow from operations or in raising
additional capital when required in sufficient amounts and on terms acceptable
to priceline.com, these failures could have a material adverse effect on
priceline.com's business, results of operations and financial condition. If
additional funds are raised through the issuance of equity securities, the
percentage ownership of its then-current stockholders would be diluted.

MARKET-RELATED RISKS

    Priceline.com currently has no floating rate indebtedness, holds no
derivative instruments and does not earn significant foreign-sourced income.
Accordingly, changes in interest rates or currency exchange rates do not
generally have a direct effect on priceline.com's financial position. However,
changes in currency exchange rates may affect the cost of international airline
tickets and international hotel room reservations offered through the
priceline.com service, and so indirectly affect consumer demand for such
products and priceline.com's revenue. In addition, to the extent that changes in
interest rates and currency exchange rates affect general economic conditions,
priceline.com would also be affected by such changes.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, Statement of Financial Accounting Standards ("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

                                       41
<PAGE>
derivative and the resulting designation. Priceline.com is required to implement
the statement in the first quarter of fiscal 2001. 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.

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 $54.2 million. Utilization of priceline.com's net
operating loss carryforwards, which begin to expire in 2018, may be subject to
certain limitations under Section 382 of the Internal Revenue Code of 1986, as
amended. Priceline.com has provided a full valuation allowance on the deferred
tax asset, consisting primarily of net operating loss carryforwards, because of
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

    A federal air transportation tax is imposed upon the sale of airline tickets
and generally is collected by the airlines selling the tickets. The tax is based
upon a percentage of the cost of transportation, which was 9% for periods prior
to October 1, 1998 and 8% thereafter. Because of the unique pricing structures
employed in the priceline.com service, such as the amount paid by the customer
for a ticket being different than the amount charged by the airline for the same
ticket with the excess payment, if any, going to priceline.com as a charge for
the use of its proprietary business method, it is not clear how this federal tax
should be calculated when sales occur using the priceline.com service.
Priceline.com has been calculating this tax based on the fare paid to the
airline for a ticket, rather than the price paid by the customer. There is a
possibility that current law requires computation of the tax based on the price
paid by the customer to priceline.com. Due to the uncertainty of how the federal
air transportation tax applies to sales of airline tickets using the
priceline.com service, priceline.com has submitted a written request to the
United States Internal Revenue Service seeking a determination of
priceline.com's federal air transportation tax obligations. Such determination
may not be favorable and may require priceline.com to collect federal air
transportation tax on the total amount paid by consumers for air travel.

    If the determination of the Internal Revenue Service is unfavorable,
priceline.com could owe $766,339 in additional taxes as of June 30, 1999.
Priceline.com has accrued for such potential liability in its condensed balance
sheet as of June 30, 1999 and is providing for such potential liability on an
ongoing basis. Priceline.com has agreed to indemnify and hold harmless certain
of its participating airlines from any liability with respect to such taxes as
well as to secure the payment of such taxes by a letter of credit.

    NON-QUALIFIED STOCK OPTIONS


    Priceline.com currently has outstanding non-qualified stock options to
purchase 26,582,391 shares issued to various employees, consultants and
directors pursuant to the 1997 Omnibus Plan and the 1999 Omnibus Plan. The
options entitle holders to purchase common stock at a weighted average exercise
price of approximately $11.46 per share, subject to adjustment in accordance
with the 1997 Omnibus Plan and the 1999 Omnibus Plan. Upon exercise of an
option, priceline.com will be required to make payments on behalf of the option
holders for certain payroll related taxes such as Social Security and Medicare.
These payroll taxes will appear as a general and administrative expense on
priceline.com's income statement and


                                       42
<PAGE>
will amount to approximately 1.5% to 2.0% of the difference between the exercise
price and the then fair market value of the common stock at the time of
exercise. However, upon exercise of outstanding options, priceline.com will be
paid the exercise price of the options that are exercised. Priceline.com also
will be entitled to an income tax deduction equal to the sum of (1) the
difference between the exercise price of the option and the then fair market
value of the common stock at the time of exercise and (2) the total amount of
payroll related tax payments. As the calculation of the expense is directly
dependent upon priceline.com's stock price and the exercise of options is within
the sole discretion of the holder of the options, the amount and timing of the
expense and the timing of the corresponding income tax deduction are not
currently able to be determined and are not within the control of priceline.com.
Priceline.com estimates that, in connection with the exercise of outstanding
options pursuant to the option exercise program, in the third quarter of 1999 it
will (x) record expenses of approximately $1.3 million in respect of such
payroll related taxes; (y) increase additional paid-in capital by approximately
$944,000 in respect of the exercise price of such options; and (z) increase
common stock by approximately $7,700 in respect of the par value of the shares
purchased upon exercise of such options.

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 its 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 June 30, 1999. Such amounts have not been
material. The additional costs to make any other products or services Year 2000
compliant will be expensed as incurred, but are not expected to be material.

                                       43
<PAGE>
    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 reliability and safety because of the Year 2000 issue. All
of these factors could have a material adverse effect on its business, financial
condition and results of operations.

    CONTINGENCY PLANS

    Priceline.com has developed a contingency plan to address situations that it
believes would arise if it fails to be Year 2000 compliant. Priceline.com has
not developed a contingency plan to address situations that may result if its
suppliers are unable to achieve Year 2000 compliance. The cost of developing and
implementing such a plan, if necessary, could be material.

                                       44
<PAGE>
                                    BUSINESS

OVERVIEW

    Priceline.com has pioneered a unique e-commerce pricing system known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price"--priceline.com collects consumer demand, in the
form of individual customer offers guaranteed by a credit card, for a particular
product or service at a price set by the customer. Priceline.com then either
communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether it can fulfill the
customer's offer on the basis of the pricing information and rules established
by the sellers. Consumers agree to hold their offers open for a specified period
of time and, once fulfilled, offers cannot be canceled. Priceline.com benefits
consumers by enabling them to save money, while at the same time benefitting
sellers by providing them with an effective revenue management tool capable of
identifying and capturing incremental revenues. By requiring consumers to be
flexible with respect to brands, sellers and product features, priceline.com
enables sellers to generate incremental revenue without disrupting their
existing distribution channels or retail pricing structures.


    Priceline.com commenced its service on April 6, 1998 with the sale of
leisure airline tickets and, during the period from launch through June 30,
1999, collected guaranteed offers for approximately 5.1 million airline tickets,
representing approximately $1.1 billion in total consumer demand, resulting in
sales of approximately 762,000 airline tickets, representing approximately
$165.2 million in revenue. During the six-month period ended June 30, 1999,
priceline.com collected guaranteed offers for approximately 1.8 million airline
tickets, representing approximately $697.5 million in total consumer demand.
This demand resulted in sales of approximately 627,000 airline tickets,
representing approximately $134.8 million in revenue. The number of offers that
priceline.com accepts is affected by a variety of factors, including the number
of reasonable offers received and the level of available inventory. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview."


    Since commencing service, the priceline.com business has grown significantly
and the priceline.com service now includes the following products and services:

    - leisure airline tickets, which now includes six domestic and 16
      international airline participants;

    - new automobiles, which was launched on a test basis in the New York
      metropolitan area in July 1998;

    - hotel room reservations, which was launched in October 1998, offers hotel
      rooms in substantially all major United States markets and includes as
      participants more than 10 leading national hotel chains; and

    - home financing services, which was launched in January 1999 with home
      mortgage services and now also includes home equity loans and refinancing
      services.

    Through the innovative use of "adaptive marketing programs," priceline.com
also markets customer acquisition programs for third parties. These programs
facilitate the completion of a higher percentage of successful transactions
through the priceline.com service while generating fee income for the company.
Priceline.com intends to continue to leverage the priceline.com brand by
expanding its product offerings to include rental cars, cruises, time shares,
vacation packages, personal and automobile loans, insurance and other financial
services products and by expanding our new car sales service to the entire U.S.
market. Priceline.com also is exploring expansion of its core "name your price"
business model to other areas of e-commerce, such as retail merchandise and the
consumer-to-consumer market.

    Priceline.com offers products and services that are provided by
participating sellers, many of whom are leaders in their industries. Twenty-two
domestic and international airlines currently participate in priceline.com's
leisure airline ticket service, including Delta, Northwest, Continental, TWA,
America West and leading international carriers. Participants in the
priceline.com hotel room reservation service include

                                       45
<PAGE>
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 home financing service, which is offered through a
joint marketing arrangement with LendingTree, an Internet-based home financing
service provider, includes a network of more than 30 participating lending
institutions.

    Priceline.com generates revenues in a variety of ways depending on the
product or service sold. With respect to its airline ticket and hotel room
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 recognizes as revenue the
customer's named price, net of taxes, and records as the cost of revenue, the
fare or rate charged by seller. With respect to priceline.com's automobile and
home financing services, a customer's offer is submitted directly to the
participating sellers who determine whether to fulfill the offer. With respect
to its automobile service, priceline.com earns a fixed fee from both the
customer and the seller after the transaction is consummated. With respect to
the home financing service, priceline.com receives marketing fees equal to a
percentage of the net revenue generated by the service, which is operated in
conjunction with LendingTree, Inc. For its adaptive marketing programs,
priceline.com earns fees 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 April 1999, among adult Americans, priceline.com was
the second most recognized e-commerce brand among the 20 leading brands included
in the survey and one of the most recognized Internet brands among the leading
brands included in the survey. Based on the study, priceline.com also believes
that, after only one year of operation, 91.1 million (or 46%) of all adult
Americans were aware of the priceline.com brand. The study also indicated that
awareness of the priceline.com brand increased over 14% since mid-1998.
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

                                       46
<PAGE>
commercial medium has been accompanied by a diversification in the type of
commerce that is conducted on the Internet and a proliferation in the types of
products and services available on the Internet.

    The Internet possesses a number of unique and commercially powerful
characteristics that differentiate it from traditional media: users communicate
or access information without geographic or temporal limitations; users access
dynamic and interactive content on a real-time basis; and users communicate and
interact instantaneously with a single individual or a group of individuals at
little or no cost. The Internet has created a dynamic and particularly
attractive medium for commerce, empowering consumers to gather more comparative
purchasing data than is feasible with traditional commerce systems, to shop in
ways that can be more convenient for them and to interact with sellers in many
new ways. As the Internet has become more accessible and widely used for
transactions, it has emerged as a primary business channel alongside the
telephone, paper-based communication and face-to-face interaction.

    LIMITATIONS OF TRADITIONAL PRICING MECHANISMS

    Under traditional retail pricing methods, sellers typically market products
to consumers under brand names at fixed retail prices. Alternatively, prices can
be established through auction processes. However, each of these forms of
seller-driven commerce has certain significant disadvantages for both sellers
and consumers. For example, in the retail pricing model, sellers who discount
prices to clear excess inventory, utilize excess capacity or increase sales
velocity, risk disruption of their existing distribution channels and damage to
their retail pricing structures. They also lose the opportunity to earn
incremental revenue from "free-riders," that is, consumers who would have been
prepared to pay the undiscounted price for the product or service, but
nevertheless obtain the benefit of the discounted price. Moreover, none of these
pricing methods allow sellers to consider the flexibility of potential buyers
before setting prices. Similarly, consumers are often forced to pay a higher
price when the seller is setting a fixed retail price for a product with added
features or under a specific brand, which the customer would otherwise have been
prepared to forgo for a lower price. Auctions force consumers to compete against
each other for the benefit of the seller, which always results in the product
being sold on the basis of the highest bid.

    While the Internet has become a significant medium for conducting business,
commerce presently conducted on the Internet is largely based upon traditional
pricing methods. Priceline.com believes that the vast information sharing and
communications power of the Internet creates an opportunity for significant
change in the way commerce or business is conducted.

THE PRICELINE.COM SOLUTION

    Priceline.com has developed a unique pricing system known as 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.

                                       47
<PAGE>
    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 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, Continental, 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

                                       48
<PAGE>
      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. 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 three 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, equity loans and
             refinancings, credit card balance consolidation and automobile and
             life insurance; and

        -  automobile sales and related financing.

      In these sectors, the priceline.com service currently offers leisure
      airline tickets, hotel rooms, home financings and 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 THE PRICELINE.COM BUSINESS MODEL. Priceline.com also intends to
      explore expansion of its core "name your price" business model to other
      areas of e-commerce. Priceline.com currently is evaluating the licensing
      of its business model to two new companies. One of these companies is
      developing a consumer-to-consumer transaction business in which buyers
      would make conditional purchase offers to acquire goods from other
      consumers. The other would enable consumers to use the Internet to name
      the price that they are willing to pay for retail merchandise, which they
      would pick up from participating retailers. However, priceline.com has not
      determined the structure of its relationship with these companies, which
      may include, among other things, licensing of the priceline.com brand and
      "name your price" business model and investment in such entities.

    - 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

                                       49
<PAGE>
      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 by telephone and provides
      customer service by telephone and e-mail 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 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.

                                       50

THE PRICELINE.COM BUSINESS MODEL

    Priceline.com believes that its unique pricing system known as a "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.

    In addition to its unique revenue structure, the defining elements of the
priceline.com business model are the following:

    - the buyer specifies or accepts a RANGE OF SUBSTITUTABILITY among brands,
      product features and/or sellers; for example, he agrees to stay at any
      three-star hotel in a certain area, agrees to fly at any time of the day
      or agrees to purchase a new car from any factory-authorized dealer;

    - the buyer NAMES THE PRICE he is prepared to pay for the products or
      services within the specified range of substitutability;

    - the buyer GUARANTEES HIS OFFER for a specified time period by securing all
      or a portion of his potential payment for the product or service with a
      major credit card;

    - companies sell products or services at prices below their currently
      available retail prices using priceline.com as a BRAND SHIELD to protect
      their retail pricing structures and channels of distribution;

    - each guaranteed offer can be consummated with products or services from
      any of a GROUP OF SELLERS; and

    - offers made through priceline.com are held open for a specified period of
      time, and CANNOT BE CANCELED by either the seller or the buyer.

    The priceline.com consumer proposition is simple and compelling: realize
immediate savings by using the Internet to name your own price when you are
willing to be flexible about brands, product features and/or sellers. A central
premise of the priceline.com consumer proposition is that in many product and
service categories there are a significant number of consumers for whom brands,
product features or sellers are interchangeable, particularly if agreeing to a
substitution among brands or sellers will result in saving money. For example,
priceline.com believes that many leisure travelers are relatively indifferent
about the brand of major airline they fly. Similarly many consumers are
indifferent to which financial services company provides them with a credit card
or home mortgage. Priceline.com also believes that many consumers prefer not to
spend time and effort engaged in an evaluative process among similar products,
brands or sellers, which they consider to be substitutable. Finally,
priceline.com is appealing to some consumers because it does not charge a
customer to submit an offer, and priceline.com's Web site provides convenient
access, available 24 hours a day, seven days a week.

    Priceline.com believes that the collection of large volumes of consumer
demand is essential to building networks of multiple sellers. Priceline.com also
believes that it is important that all of the demand

                                       51
<PAGE>
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.
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. The priceline.com service now includes the sale
of new automobiles, hotel room reservations and home financing services.
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. Priceline.com also intends to explore
expansion of its core "name your price" business model to other areas of
e-commerce, such as the consumer-to-consumer market.

    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

                                       52
<PAGE>
since the launch of the business, from an initial group of two domestic airlines
and four international airlines, to a total of six domestic airlines and 16
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;

    - 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, plus applicable taxes and standard processing fees, and
the ticket is delivered to the customer by the delivery method specified by the
customer. Approximately 94% of domestic tickets issued through priceline.com are
electronic tickets. Priceline.com earns the spread, if any, between the
customer's offered price and the cost to purchase the ticket from the airline,
and the handling fee charge paid by the customer on each ticket.

    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 room reservation service currently is

                                       53
<PAGE>
available in substantially all major cities and metropolitan areas in the United
States. Seller participants in the hotel room 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 room reservation service operates in a manner similar
to its airline ticket service. Consumers are required to accept certain
trade-offs with respect to brands or product features in return for saving
money. For example, consumers are required to accept a reservation in any hotel
within a specified geographic area within a designated "class" of service (1, 2,
3, 4 or 5-star) and must accept limitations on changes and cancellations.
Priceline.com determines the class of service for each participating hotel based
upon published industry reports, the amenities available at each property and
other factors such as age and decor. As with the airline ticket service, the
target market for priceline.com's hotel room reservation service is the leisure
travel market.

    Consumers can make offers for a hotel room reservation through the
priceline.com Web site. 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 room 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
room 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 room 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 room 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 FINANCING SERVICES.  Priceline.com introduced its home financing
service in January 1999. Priceline.com's financing 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 home financing
service on the priceline.com Web site and for consumer marketing. LendingTree
serves as the back-end processing system, which presents offers received through
priceline.com to multiple mortgage lending institutions for consideration. There
are currently more than 30 lenders participating in

                                       54
<PAGE>

the home financing services through LendingTree. See "--Strategic
Alliances--Home Financing Alliances."


    To obtain a home mortgage, refinancing or home equity loan through the
priceline.com service, consumers access the priceline.com Web site and specify
the amount of the loan, the term, the interest rate and the points that 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 good-faith
deposit of $200 that is applied towards closing costs. The good-faith deposit is
charged by a lender only when a customer's offer is accepted. Priceline.com does
not charge the customer any fees for the use of its home financing services.
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 consumers whether their
offer has been accepted within six business hours, between the hours of 8:00
a.m. and 8:00 p.m., Eastern Standard Time. If a customer's offer is not accepted
within six business hours, priceline.com notifies the customer if it has
received any counter-offers from participating lenders. Participating lenders
may submit counter-offers for up to two business days following the customer's
offer. Customers may check the status of any counter-offers by accessing the
priceline.com Web site. Priceline.com generates revenues with respect to its
home financing service in the form of marketing fees paid directly by
LendingTree.

    Priceline.com is exploring the possibility of entering into a joint venture
with a subsidiary of a federally chartered thrift institution that would offer
to provide mortgage loans through the priceline.com service. Priceline.com
currently expects that such joint venture would participate in the priceline.com
service along with other mortgage lenders in the LendingTree network.

    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 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, automobile 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 its new car sales service on a test basis in the
New York metropolitan area in July 1998. Priceline.com utilized the New York
market to learn more about automobile sales over the Internet and to develop
product features and systems support. In July 1999, priceline.com launched a
similar test in the Tampa, Florida market, and expects to expand further in the
state of Florida, as well as into the states of California and Michigan during
the third quarter of 1999. Based on published industry data, the New York
metropolitan area represents approximately 10% of all consumer demand for new
automobiles in the United States, while California represents approximately 11%
and Florida represents approximately 9%. Additionally, the Detroit metropolitan
area provides access to the three largest U.S. auto-makers. Subject to achieving
positive results in these markets and receipt of appropriate state

                                       55
<PAGE>
regulatory approvals and authorizations necessary to conduct our new car sales
service, priceline.com expects to become operational in the 48 contiguous states
during the first quarter of 2000. Priceline.com recently entered into a
co-marketing agreement with AutoNation, Inc., a leading national automotive
retailer. The agreement initially provides priceline.com with access to
AutoNation's inventory and dealerships in the Tampa, Florida market and provides
for expansion into other markets in the future.

    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, the
customer identifies the exact vehicle desired to be purchased or leased,
including the make, model and specified options, the geographic area in which
the customer is willing to pick up the vehicle and the purchase price or lease
price the customer is willing to pay. All sales are made through factory
authorized dealers. 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.
Additionally, priceline.com also supplies an estimated market price, based on
recent sales of the selected vehicle.

    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.

    Currently, priceline.com does not offer financing arrangements through its
new car sales service. However, to assist consumers in determining whether they
can afford a particular vehicle, or what purchase price to offer, we provide
estimated month payment calculations, a "budget work-sheet" and a financing
calculator on our Web site. Priceline.com also allows consumers to request
financing from the accepting factory authorized dealer and to condition their
offers on obtaining such financing.

    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 cars 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 one round-trip airline
ticket can immediately increase the amount of his offer by $40 by applying
online for a First USA credit card. If the customer obtains the requested
ticket, he still pays only the amount contained in his original offer, plus
applicable taxes and standard processing fees. 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 First USA credit card,
priceline.com would increase the customer's offer by up to an additional $40 to
enable the customer a greater chance of purchasing the ticket. If priceline.com
is able to purchase the ticket for $240 or less, the customer would still only
have to pay his original offer price of $200, plus applicable taxes and fees.

    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.

    During 1998 and the first quarter of 1999, our adaptive marketing revenues
were derived primarily from fees paid by Capital One Bank for qualifying credit
card applications submitted over the priceline.com service in connection with
customer offers for airline tickets. Effective May 1, 1999, our relationship
with Capital One ended. Since that time, our credit card adaptive marketing
program revenues have been attributable to our adaptive marketing relationship
with First USA Bank, a leading national credit card issuer. Under the First USA
adaptive marketing program, priceline.com enables its customers to increase the
amount of their offers by applying online for a First USA credit card and offers
other promotions linked to the First USA customer acquisition program. The fee
structure of the First USA program is based on different factors than the
factors that were applicable under the Capital One program and the First USA
program is subject to certain early termination and repricing rights of First
USA.

    Priceline.com also has an adaptive marketing agreement with E*TRADE, under
which E*TRADE compensates priceline.com for offering priceline.com customers the
opportunity to open an account with E*TRADE while visiting or making an offer on
the priceline.com Web site. While the program originally related to
priceline.com's initial public offering, it now applies to offers by customers
for products and services over the priceline.com service. The E*TRADE adaptive
marketing program is currently operated under an oral agreement and may be
terminated at any time.

    Priceline.com recently has entered into adaptive marketing agreements with
Sprint Communications Company L.P., Discover Financial Services, Inc. and
Earthlink Network, Inc. The Sprint agreement is a short-term agreement under
which priceline.com, during a twelve-week test program, will earn fees from
Sprint in connection with customer agreeing to switch their long distance
telephone service to Sprint. Priceline.com and Sprint are currently in the
process of defining the program and the launch date has not yet been determined.
We are also evaluating similar programs with other long distance carriers.

    Under the Discover adaptive marketing program, selected customers will be
able to increase the amount of their offers by a specified amount by applying
online for a Discover credit card through the priceline.com service.
Priceline.com will receive a fee from Discover Financial Services for each
qualifying credit card application submitted through the priceline.com service.
Priceline.com will also receive a fee

                                       57
<PAGE>
for any qualifying upgrade of an established Discover credit card account
submitted through the priceline.com service. The Discover adaptive marketing
program is expected to be implemented during the third quarter of 1999 and will
be offered to selected customers who have already participated, or who have
declined participation, in the First USA adaptive marketing program.

    Under priceline.com's adaptive marketing program with EarthLink Network,
Inc., an internet service provider, priceline.com will earn fees when its
customers open accounts with EarthLink and upon such accounts being open for a
specified period of time. No specific date has been set for the launch of the
EarthLink program.

    In addition, Priceline.com is exploring and has taken steps to expand its
adaptive marketing programs into a wide range of other products and services for
its customers. See "Risk Factors--We are Dependent on Adaptive Marketing
Programs" and "--Strategic Alliances--Adaptive Marketing Alliances."

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 June 30,
1999, priceline.com incurred $59.7 million for sales and marketing expense. It
intends to continue to pursue an aggressive marketing strategy designed to
promote brand awareness and the concept that consumers can save money on a wide
range of products and services through priceline.com. Underlying priceline.com's
marketing strategy is the company's belief that its target market is all
consumers, not just Internet-savvy consumers. Substantially all of such spending
has been for radio and newspaper advertising. Priceline.com's campaign features
the actor William Shatner as its spokesperson.

    Priceline.com supplements its paid advertising and promotion with targeted
media coverage. Priceline.com has been featured in hundreds of news stories in
national publications such as THE NEW YORK TIMES, THE WALL STREET JOURNAL AND
USA TODAY, reflecting the intuitive appeal of the priceline.com business model
and its strong word-of-mouth support. In addition, priceline.com engages in
grass roots marketing such as promotional events on college campuses and
co-promotions with popular media such as MTV.

    Priceline.com believes that the priceline.com service has achieved
widespread brand awareness. Based upon the results of an independent research
study conducted for priceline.com, the company believes that, as of April 1999,
among adult Americans, priceline.com was the second most recognized e-commerce
brand among the 20 leading brands included in the survey and one of the most
recognized Internet brands among the leading brands included in the survey.
Based on the study, priceline.com also believes that, after only one year of
operations, 91.1 million (or 46%) of all adult Americans were aware of the
priceline.com brand. 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 six
domestic and 16 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;

                                       58
<PAGE>
    - consumers must be willing to fly on any participating airline;

    - consumers must be willing to depart at any time after 6 a.m. and land any
      time before 10 p.m. on the requested dates;

    - all offers must be guaranteed with a major credit card; and

    - consumers are limited in their ability to make multiple offers with
      respect to the same travel itinerary.

    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. Priceline.com's agreement with Delta, subject to
various exceptions, requires Delta's approval of the addition of new carriers to
the priceline.com service, restricts the routes for which tickets may be offered
by specified carriers through the priceline.com service and imposes limitations
on the code share arrangements of specified carriers. Delta also may require the
exclusion of specific markets in order for certain other airlines to
participate. These provisions could limit priceline.com's ability to expand its
airline ticket service. In addition, priceline.com's ability to transfer or
license its intellectual property to other travel providers is limited in the
manner set forth in the agreement.

    In connection with the Airline Participation Agreement with Delta,
priceline.com also issued a warrant to Delta to purchase up to 18,619,402 shares
of common stock at an exercise price of approximately $0.93 per share. The Delta
warrant will become exercisable at the earlier of December 31, 2005, or Delta's
achievement of certain performance thresholds of ticket sales.

    Priceline.com also has issued to several participating airlines warrants to
purchase an aggregate of 3,187,500 shares of common stock, comprised of warrants
to purchase 937,500 shares of common stock at an exercise price of $3.20 per
share, warrants to purchase 1,250,000 shares of common stock at an exercise
price of $6.40 per share and warrants to purchase 1,000,000 shares of common
stock at an exercise price of approximately $97.41 per share. The warrants
having an exercise price of $3.20 per share become exercisable on October 28,
1999. With respect to the warrants having an exercise price of $6.40 per share,
warrants relating to one-half of the underlying shares become exercisable on
December 31, 1999, and warrants relating to the remaining underlying shares
become exercisable on December 31, 2000, subject to earlier termination of such
warrants in the circumstances identified in the warrant agreement. The warrants
having an exercise price of $97.41 per share become exercisable upon the earlier
of July 16, 2004 or the airline's achievement of various performance thresholds
based upon ticket sales.


HOME FINANCING ALLIANCES


    In connection with priceline.com's home financing 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 participating 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

                                       59
<PAGE>
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.

    Priceline.com is exploring the possibility of entering into a joint venture
with a subsidiary of a federally chartered thrift institution that would offer
to provide mortgage loans through the priceline.com service. Priceline.com
currently expects that such joint venture would participate in the priceline.com
service along with other mortgage lenders in the LendingTree network.

    HOTEL ALLIANCES

    In connection with priceline.com's hotel service, priceline.com has entered
into letter agreements with 39 hotel groups, which cover numerous brands and
include several of the leading national 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.

    AUTOMOTIVE ALLIANCE

    Priceline.com has entered into a co-marketing agreement with AutoNation,
Inc., a leading national automotive retailer. Under the terms of the
co-marketing agreement, consumer offers for automobiles submitted through the
priceline.com service will be offered to AutoNation dealers first. If no
AutoNation dealers accept a customer's offer, such offer will be submitted to
other dealers in the market. The service is being offered initially in the Tampa
and St. Petersburg, Florida markets, with plans to expand to additional markets
nationwide.

    ADAPTIVE MARKETING ALLIANCES

    During 1998 and the first quarter of 1999, our adaptive marketing revenues
were derived primarily from fees paid by Capital One Bank for qualifying credit
card applications submitted over the priceline.com service in connection with
customer offers for airline tickets. Effective May 1, 1999, our relationship
with Capital One ended. Since that time, our credit card adaptive marketing
program revenues have been attributable to our adaptive marketing relationship
with First USA Bank, a leading national credit card issuer. Under the First USA
adaptive marketing program, priceline.com enables its customers to increase the
amount of their offers by a specified amount by applying online for a First USA
credit card and offers other promotions linked to the First USA customer
acquisition program. The fee structure of the First USA program is based on
different factors than the factors that were applicable under the Capital One
program. Under the First USA program, priceline.com earns fees (1) upon the
opening of credit card accounts originated through the priceline.com service, up
to a specified maximum amount of five million accounts, subject to reduction
under certain circumstances by First USA; (2) upon the activation of credit card
accounts acquired for First USA through the priceline.com service and based upon
the use of such accounts; and (3) for transfers of balances from other credit
cards to First USA credit cards through the priceline.com service.

    The First USA agreement has a term of five years, subject to certain earlier
termination and repricing rights of First USA. For example, subject to
priceline.com's rights of renegotiation, First USA has the right to terminate
the agreement after one year (and earlier under certain circumstances) if its
financial returns under the adaptive marketing program are not at least
equivalent to certain agreed upon levels. In

                                       60
<PAGE>
addition, a portion of the fees earned under the First USA program is required
to be reinvested in program incentives. The full financial statement impact of
the shift from the Capital One adaptive marketing program to the First USA
adaptive marketing program will not be known until completion of future periods.

    Priceline.com also has an adaptive marketing agreement with E*TRADE, under
which E*TRADE compensates priceline.com for offering priceline.com customers the
opportunity to open an account with E*TRADE while visiting or making an offer on
the priceline.com Web site. While the program originally related to
priceline.com's initial public offering, it now applies to offers by customers
for products and services over the priceline.com service. The E*TRADE adaptive
marketing program is currently operated under an oral agreement.

    Priceline.com recently has entered into adaptive marketing agreements with
Sprint Communications Company L.P., Discover Financial Services, Inc. and
Earthlink Network, Inc. The Sprint agreement is a short-term agreement under
which priceline.com, during a twelve-week test program, will earn fees from
Sprint in connection with customers agreeing to switch their long distance
telephone service to Sprint. Priceline.com and Sprint are currently in the
process of defining the program and the launch date has not yet been determined.
We are also evaluating similar programs with other long distance carriers.

    Under the Discover adaptive marketing program, selected customers will be
able to increase the amount of their offers by a specified amount by applying
online for a Discover credit card through the priceline.com service.
Priceline.com will receive a fee from Discover Financial Services for each
qualifying credit card application submitted through the priceline.com service.
Priceline.com will also receive a fee for any qualifying upgrade of an
established Discover credit card account submitted through the priceline.com
service. The Discover adaptive marketing program is expected to be implemented
during the third quarter of 1999 and will be offered to selected customers who
have already participated, or who have declined participation, in the First USA
adaptive marketing program.

    Under priceline.com's adaptive marketing program with EarthLink Network,
Inc., an internet service provider, priceline.com will earn fees when its
customers open accounts with EarthLink and upon such accounts being open for a
specified period of time. No specific date has been set for the launch of the
EarthLink program.

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;

    - traditional travel agencies;

    - consolidators and wholesalers of airline tickets and other travel
      products, including online consolidators such as Cheaptickets.com;

    - 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 AutoNation, Auto-by-Tel and Microsoft's
CarPoint. With respect to financial service products, priceline.com's
competitors include:

    - banks and other financial institutions;

                                       61
<PAGE>
    - online and traditional mortgage and insurance brokers, including
      mortgage.com, Quicken Mortgage, E-Loan and iOwn, Inc.; 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 Amazon.com, 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 room 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

                                       62
<PAGE>
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.

    Priceline.com also offers phone service through its toll-free number,
1-800-Priceline, which allows consumers who do not have access to a computer to
phone in their orders. 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. Because priceline.com is an
Internet business, it intends to phase out its telephone ordering and credit
card submission services over time and, in the future, will use its toll-free
number only to provide customer service.

INTELLECTUAL PROPERTY

    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 three issued United States patents, No.
5,794,207, No. 5,797,127 and No. 5,897,260, as well as 25 pending United States
patent applications and four pending international patent application.
Priceline.com is in the process of filing at least three more patent
applications, with an ongoing program for identifying and protecting new
inventions. Priceline.com's core business method patent is directed to a unique
buyer-driven commerce system using a computer to collect credit card-backed or
other financial account-backed conditional purchase offers to present to
multiple sellers, receive one or more acceptances or fulfillments of these
offers, and use the credit card or other financial account to provide a payment
to one or more of the sellers. The pending patent applications are directed to
various operational features of the system, as well as to product-specific
enhancements.

    While priceline.com believes that its core buyer-driven commerce patent,
together with its pending patent applications, help to protect the priceline.com
business, there can be no assurance that (1) the core buyer-driven patent or any
other patent can be successfully defended against challenges by third parties;
(2) the pending patent applications will result in the issuance of patents; (3)
competitors or potential competitors of priceline.com will not devise new
methods of competing with the company that are not covered by priceline.com's
patent or patent applications; (4) because of variations in the application of
our business model to each of our products and services, our core buyer-driven
commerce patent may not be effective in preventing one or more third parties
from utilizing a copycat business model to offer the same product or service in
one or more categories; (5) new prior art will not be discovered which may
diminish the value of or invalidate an issued patent; or (6) 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 appears to use customer-offer based transaction models.

    Walker Digital currently owns the assets and intellectual property related
to two new areas of e-commerce into which priceline.com may expand its "name
your price" business model, one involving consumer-to-consumer sales and the
other involving the sale of retail merchandise. Priceline.com may license its
brand name and "name your price" business model to two new companies formed to
develop these businesses. Walker Digital may contribute assets and intellectual
property to these companies in return for an equity interest in these companies.

                                       63
<PAGE>
    Walker Digital owns the intellectual property rights underlying the
technology associated with priceline.com's adaptive marketing programs. Walker
Digital has licensed to priceline.com the right to use these intellectual
property rights under a perpetual, non-exclusive, royalty-free license
agreement. Walker Digital has several pending United States patent applications
directed to different aspects of the processes and technology supporting
adaptive marketing programs.

    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.com
is registered as a "seller of travel" under the California Seller of Travel Act
and is a member of the Airlines Reporting Corporation. In addition, a number of
state travel laws and regulations require compliance with specific disclosure,
bond and/or other requirements.

    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. With
the planned expansion of its new automobile service from the New York
metropolitan area to all 48 contiguous states, priceline.com will attempt to
register as an automobile broker/dealer in the jurisdictions where registration
is required provided that it can reasonably comply with the requirements for
registration imposed by each jurisdiction. However, priceline.com may not be
able to register in all states. For example, priceline.com will not be able to
register in a jurisdiction that requires a dealer zoned lot or a franchise
agreement with manufacturers of the automobiles to be sold. Priceline.com will
work with the regulators of the various jurisdictions to obtain waivers of such
requirements, but it may not be successful in its efforts.


    In jurisdictions where priceline.com cannot obtain registration, it is
possible that state regulatory bodies could take a strict enforcement position
and priceline.com may be unable to continue to make its new automobile services
available in those jurisdictions.


                                       64

    HOME FINANCING SERVICES

    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 financing service in January 1999.
LendingTree serves as the back-end processing system, which presents offers
received through the priceline.com service to multiple mortgage lending
institutions for consideration, for all of priceline.com's home financing
services,
Priceline.com provides and is responsible for maintaining the home financing
service on its Web site and develops and purchases all advertising. LendingTree
compensates 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 back-end processing system, which presents offers
we receive to multiple mortgage lending institutions for consideration, for the
home financing service on priceline.com's Web site and is responsible for
maintaining the necessary and appropriate state registrations and licenses
associated with LendingTree's 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.

    Priceline.com is exploring the possibility of acquiring a minority interest
in, and licensing the priceline.com name and business model to, a newly formed
subsidiary of a federally chartered savings and loan association. This entity
may be known as "priceline.mortgage.com" and also may serve as an entity that
could accept mortgage applications or mortgage qualification loans.

    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 also is 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.

                                       65
<PAGE>
    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
recently received a notice from the United States Patent and Trademark Office
that an undisclosed patent applicant, believed by priceline.com to be Woolston,
is seeking to provoke an interference on priceline.com's core buyer-driven
commerce patent. Priceline.com currently is awaiting information from the Patent
Office regarding whether it will initiate an interference proceeding concerning
Woolston's patent application and priceline.com's core buyer-driven commerce
patent. An interference is an administrative proceeding instituted in the Patent
Office to determine questions of patentability and priority of invention between
two or more parties claiming the same patentable invention. There is no
statutory period within which the Patent Office must act on an interference
request. If an interference is declared and proceeds through a final hearing in
the Patent Office, a final judgment is made by the Patent Office as to
inventorship. Following such final judgment, appeals could be made in Federal
court. While there can be no certainty as to time periods, interference
proceedings typically take years to resolve.


    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from the
priceline.com core buyer-driven commerce patent. In order to make this showing,
he would have to prove, among other things, that he invented the subject matter
of the priceline.com claims before the inventors of the priceline.com patent. If
the Patent Office were to find that Woolston's patent application supported the
copied priceline.com claims, it would resolve the interference by awarding
inventorship to the party with the earliest proven date of invention. Woolston
announced in February 1999 an agreement to license his issued patent and pending
patent applications to the owner of a competing Internet travel service.

    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While

                                       66
<PAGE>
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 and pay damages from the date such patent issued at a
cost which could significantly adversely affect priceline.com's business. If
Woolston prevailed in both an interference and an infringement action, then
priceline.com could be enjoined from conducting business through the
priceline.com service to the extent covered by the patent claims awarded to
Woolston. In addition, defense of the interference action may be expensive and
may divert management attention away from priceline.com's business.

    On January 19, 1999, a lawsuit was filed in the United States District Court
for the Northern District of California by Marketel International, Inc., a
California corporation, under the caption MARKETEL INTERNATIONAL INC. V.
PRICELINE.COM ET. AL.,No. C-99-1061 (N.D. CA 1999), against priceline.com,
Priceline Travel, Walker Asset Management, Walker Digital, Mr. Jay S. Walker,
priceline.com's Founder and Vice Chairman, and Mr. Andre Jaeckle, an individual
who made a $1.0 million loan to priceline.com bearing interest at a rate of 6%
per year and, in connection with the loan, received warrants, which have
subsequently been fully exercised, to purchase 62,500 shares of our common
stock. On February 22, 1999, Marketel filed an amended complaint, and March 17,
1999, Marketel filed a second amended complaint. The second amended complaint
includes as defendants, Mr. Timothy G. Brier, our Executive Vice President,
Travel, Mr. Bruce Schneier, and an individual and consultant to Walker Digital,
and Mr. James Jorasch, an individual and employee of Walker Digital, and 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 second amended
complaint, Marketel alleges, among other things, that the defendants conspired
to misappropriate Marketel's business model, which it describes as a
buyer-driven electronic marketplace for travel services and its appurtenant
techniques, market research, forms, plans and processes, and which an executive
of Marketel allegedly provided to Messrs. Walker and Jaeckle in confidence
approximately ten years ago. The second amended complaint also alleges that
three former Marketel employees are the actual sole inventors or co-inventors of
U.S. patent No. 5794207, which was issued on August 11, 1998 with Jay S. Walker,
Bruce Schneier and James Jorasch listed as the inventors and which patent has
been assigned to priceline.com. Marketel asks that the patent's inventorship be
corrected accordingly.

    Based upon publicly available information, priceline.com believes that
Marketel's fax and fee-based business was launched in 1991 and ceased operations
seven months later. Priceline.com's Internet-based model was independently
developed by Walker Digital and priceline.com, and practiced by priceline.com
starting in 1998. Based on publicly available information and Marketel's second
amended 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 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, February 10, 1999 and March 31, 1999, the defendants
filed their answer, amended answer and answer to second amended complaint,
respectively, in which they denied the material allegations of liability in the
complaints. Priceline.com and all other defendants strongly dispute the material
legal and factual allegations contained in Marketel's second amended complaint
and believe that

                                       67
<PAGE>
the second amended complaint is without merit. Priceline.com intends to defend
vigorously against the action. Since May 28, 1999, there has been a discovery
stay in effect, which was caused by the withdrawal of Marketel's counsel.
Marketel has retained new counsel, and priceline.com now anticipates moving
forward with discovery. Defending the lawsuit may involve significant expense
and, due to the inherent uncertainties of litigation, there can be no certainty
as to the ultimate outcome. Pursuant to the terms of the indemnification
obligations contained in the Purchase and Intercompany Agreement with Walker
Digital, Walker Digital has agreed to indemnify priceline.com for damages,
liability and legal expenses incurred in connection with the Marketel
litigation.

    From time to time priceline.com has been and expects to continue to be
subject to legal proceedings and claims in the ordinary course of business,
including claims of alleged infringement of third party intellectual property
rights by the company. Such claims, even if not meritorious, could result in the
expenditure of significant financial and managerial resources.

EMPLOYEES


    Currently, priceline.com has 266 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 40,000 square feet of leased office space located in Stamford,
Connecticut. Priceline.com is subleasing this office space from Walker Digital
on a month-to-month basis. Priceline.com also has guaranteed Walker Digital's
obligations under a lease of office space in New York City that is used by both
companies. Priceline.com anticipates that it will require additional space
within the next 12 months to accommodate its anticipated growth and that
suitable office space will be available on commercially reasonable terms.
Priceline.com currently is negotiating a lease of new premises in Connecticut.
The premises are substantially larger than priceline.com's current premises and,
if a lease is signed, priceline.com's rental expense is likely to increase
significantly.

(a) Member of the Compensation Committee.

(b) Member of the Audit Committee.

    RICHARD S. BRADDOCK has served as Chairman of the board of directors and
Chief Executive Officer of priceline.com since August 1998. From December 1997
to January 1999, he served as the non-executive Chairman of True North
Communications, Inc., an advertising company, and Ion Laser Technology, a laser
technology company. From September 1996 to August 1997, he served as a special
advisor to General Atlantic Partners, LLC, a private equity fund. Mr. Braddock

1997 Omnibus Plan as of August 10, 1999. In February 1999, priceline.com
established the priceline.com Incorporated 1999 Omnibus Plan, pursuant to which
awards will be made to certain officers, other employees, consultants and
directors of priceline.com from time to time following the consummation of this
offering. The maximum number of shares of common stock reserved for the grant or
settlement of awards under the 1999 Omnibus Plan is 9,375,000, subject to
adjustment. Of such number, options covering 3,829,505 shares of common stock
were outstanding under the 1999 Omnibus Plan as of August 10, 1999.


    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

                                       74
<PAGE>
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 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

                                       75
<PAGE>
provisions of agreements evidencing awards; and to make all other determinations
deemed necessary or advisable for the administration of the 1997 Omnibus Plan.

    The compensation committee may, in its absolute discretion, without
amendment to the 1997 Omnibus Plan, (a) accelerate the date on which any option
or stand-alone appreciation right granted under the 1997 Omnibus Plan becomes
exercisable, waive or amend the operation of provisions respecting exercise
after termination of employment or otherwise adjust any of the terms of such
option or stand-alone appreciation right, (b) accelerate the vesting or waive
any condition imposed with respect to any restricted stock, phantom stock or
other awards and (c) otherwise adjust any of the terms applicable to any award.

    AWARDS UNDER THE 1997 OMNIBUS PLAN

    STOCK OPTIONS; STOCK APPRECIATION RIGHTS

    Unless otherwise determined by the compensation committee, options granted
pursuant to the 1997 Omnibus Plan will become exercisable ratably over three
years commencing on the first anniversary of the date of grant, but in no event
may an option be exercised more than 10 years following the date of its grant.
The "option exercise price," which is the purchase price per share payable upon
the exercise of an option, will be established by the compensation committee;
PROVIDED, HOWEVER, that incentive stock options may not have an exercise price
less than the fair market value of a share of common stock on the date of grant.
The option exercise price is payable by any one of the following methods or a
combination thereof, to the extent permitted by the compensation committee: (1)
in cash or by personal check, certified check, bank cashier's check or wire
transfer; (2) subject to the approval of the compensation committee, in common
stock owned by the participant for at least six months prior to the date of
exercise and valued at their fair market value on the effective date of such
exercise; or (3) subject to the approval of the compensation committee, by such
other provision as the compensation committee may from time to time authorize.

    The compensation committee also has the authority to specify, at the time of
grant or, with respect to non-qualified stock options at or after the time of
grant, that a participant shall be granted a new non-qualified stock option,
otherwise known as a "reload option," for a number of shares of common stock
equal to the number of shares of common stock surrendered by the participant
upon exercise of all or a part of an option in the manner described above,
subject to the availability of common stock under the 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

                                       76
<PAGE>
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.

    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

                                       77
<PAGE>
90 days after termination of employment) or if the optionee subsequently engages
in a "disqualifying disposition," as described below.

    A sale or exchange by an optionee of shares acquired upon the exercise of an
incentive stock option more than one year after the transfer of the shares to
such optionee and more than two years after the date of grant of the incentive
stock option will result in any difference between the net sale proceeds and the
exercise price being treated as long-term capital gain or loss to the optionee.
If such sale or exchange takes place within two years after the date of grant of
the incentive stock option or within one year from the date of transfer of the
incentive stock option shares to the optionee, such sale or exchange will
generally constitute a "disqualifying disposition" of such shares that will have
the following results: any excess of (x) the lesser of (1) the fair market value
of the shares at the time of exercise of the incentive stock option and (2) the
amount realized on such disqualifying disposition of the shares over (y) the
option exercise price of such shares, will be ordinary income to the optionee,
subject to applicable withholding taxes, and priceline.com will be entitled to a
tax deduction in the amount of such income. Any further gain or loss after the
date of exercise generally will qualify as capital gain or loss and will not
result in any deduction by priceline.com.

    APPRECIATION RIGHTS

    The grant of appreciation rights has no federal income tax consequences at
the time of grant. Upon the exercise of appreciation rights, the amount received
is generally taxable as ordinary income, and priceline.com is entitled to a
corresponding deduction.

    RESTRICTED STOCK

    A grantee will not recognize any income upon the receipt of restricted stock
unless the holder elects under Section 83(b) of the Code, within thirty days of
such receipt, to recognize ordinary income in an amount equal to the fair market
value of the restricted stock at the time of receipt, less any amount paid for
the shares. If the election is made, the holder will not be allowed a deduction
for amounts subsequently required to be returned to priceline.com. If the
election is not made, the holder will generally recognize ordinary income, on
the date that the restrictions to which the restricted stock are subject are
removed, in an amount equal to the fair market value of such shares on such
date, less any amount paid for the shares. At the time the holder recognizes
ordinary income, priceline.com generally will be entitled to a deduction in the
same amount.

    Generally, upon a sale or other disposition of restricted stock with respect
to which the holder has recognized ordinary income, for example, if a Section
83(b) election was previously made or the restrictions were previously removed,
the holder will recognize capital gain or loss in an amount equal to the
difference between the amount realized on such sale or other disposition and the
holder's basis in such shares.

    PHANTOM STOCK

    The grant of phantom stock has no federal income tax consequences at the
time of grant. Upon the receipt of payment, the amount received is generally
taxable as ordinary income, and priceline.com is entitled to a corresponding
deduction.

    OTHER TYPES OF AWARDS

    The grant of any other stock-based award generally will not result in income
for the grantee or in a tax deduction for priceline.com. Upon the settlement of
such an award, the grantee will recognize ordinary income equal to the aggregate
value of the payment received, and priceline.com generally will be entitled to a
tax deduction in the same amount.

PRICELINE.COM INCORPORATED 1999 OMNIBUS PLAN

    In February 1999, priceline.com established the 1999 Omnibus Plan. The 1999
Omnibus Plan is intended to promote the long-term financial interests and growth
of priceline.com by providing employees of priceline.com with appropriate
incentives and rewards to encourage them to enter into and continue in the
employ of the company and to acquire a proprietary interest in the long-term
success of the company; and to reward the performance of individual officers,
other employees, consultants and directors in fulfilling their responsibilities
for long-range achievements.

    GENERAL

    The 1999 Omnibus Plan provides for the granting of awards to such officers,
other employees, consultants and directors of priceline.com and its affiliates
as the compensation committee, which is the committee of the board of directors
appointed to administer the Plan may select from time to time. Awards under the
1999 Omnibus Plan may be made in the form of incentive stock options,
non-qualified stock options, restricted stock or other awards.

    The maximum number of shares of common stock reserved for the grant or
settlement of awards under the 1999 Omnibus Plan is 9,375,000 subject to
adjustment as provided in the 1999 Omnibus Plan. The maximum number of shares of
common stock that may be awarded in respect of options, restricted stock and
other awards to a single individual in any given year may not exceed 9,375,000,
3,125,000 and 6,250,000, respectively, which amounts are subject to adjustment
as described below. Awards (either as options, restricted stock or other awards)
will be made in a manner consistent with Section 162(m) of the Code. Shares of
common stock acquired upon the exercise or settlement of awards may, in whole or
in part, be authorized but unissued shares or shares that shall have been or may
be reacquired by priceline.com in the open market, in private transactions or
otherwise. If any shares subject to an award are forfeited, cancelled, exchanged
or surrendered or if an award otherwise terminates or expires without a
distribution of shares to the holder of such award, the shares of common stock
with respect to such award will, to the extent of any such forfeiture,
cancellation, exchange, surrender, termination or expiration, again be available
for awards under the 1999 Omnibus Plan.

    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

                                       79
<PAGE>
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 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

                                       80
<PAGE>
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. As of
August 10, 1999, options covering 3,829,505 shares of common stock were
outstanding under the 1999 Omnibus Plan. 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.

    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

                                       81
<PAGE>
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.

RELATIONSHIP WITH WALKER DIGITAL

    The priceline.com core buyer driven commerce business model and related
intellectual property rights were initially developed by Walker Digital, a
technology research and development company that was founded and is controlled

office space in a building in New York City that is used by both companies. The
lease provides for annual rental payments of approximately $170,000 plus
expenses for a term of five years.

    Pursuant to the terms of the indemnification obligations contained in the
Purchase and Intercompany Agreement, Walker Digital has agreed to indemnify
priceline.com for damages, liability and legal expenses incurred in connection
with the Marketel litigation.

(a) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission and generally includes voting or
    investment power with respect to securities. Shares of common stock and
    options or warrants that are currently exercisable or exercisable within 60
    days of August 10, 1999 are deemed to be outstanding and to be beneficially
    owned by the person holding such options for the purpose of computing the
    percentage ownership of such person, but are not treated as outstanding for
    the purpose of computing the percentage ownership of any other person. The
    number of shares being sold excludes any shares that may be sold as a result
    of the exercise by the underwriters of their over-allotment option, which if
    exercised, will be allocated pro rata among the selling stockholders.

      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. 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 of the States;

    - 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 supervision
      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. Furthermore, 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, such 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. investor's holding period), more than 5 percent of the outstanding
    common stock. Priceline.com

                                       91
<PAGE>
    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, 2000, 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. 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 "resident" (as 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.

                          DESCRIPTION OF CAPITAL STOCK


    The authorized capital stock of priceline.com consists of 1,000,000,000
shares of common stock, par value $0.008 per share, and 150,000,000 shares of
preferred stock, par value $0.01 per share, of priceline.com. Upon completion of
this offering, there will be 146,782,296 outstanding shares of common stock,
outstanding options to purchase 26,582,391 shares of common stock and
outstanding warrants to purchase 20,283,573 shares of common stock.


COMMON STOCK

    Subject to preferences that may apply to shares of preferred stock
outstanding at the time, the holders of outstanding shares of common stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the board of directors may from time to time
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
common stock is not entitled to preemptive rights and is not subject to
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
ratably in the distribution of all of the company's assets remaining available
for distribution after satisfaction of all its liabilities and the payment of
the liquidation preference of any outstanding preferred stock. Each outstanding
share of common stock is, and all shares of common stock to be outstanding upon
completion of this offering will be, fully paid and nonassessable.

PREFERRED STOCK

    The board of directors has the authority, within the limitations and
restrictions stated in the certificate of incorporation, to provide by
resolution for the issuance of shares of preferred stock, in one or more classes
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. See
"Risk Factors--Anti-Takeover Provisions Affecting Us Could Prevent or Delay a
Change of Control."

OPTIONS


    As of August 10, 1999, (1) options to purchase a total of 26,582,391 shares
of common stock were outstanding; and (2) up to 5,729,069 additional shares of
common stock may be subject to options granted in the future under the 1997
Omnibus Plan or the 1999 Omnibus Plan. All of the options contain standard
anti-dilution provisions. See "Management--Priceline.com Incorporated 1997
Omnibus Plan," "--Priceline.com Incorporated 1999 Omnibus Plan" and "--Summary
of Compensation."

    As of August 10, 1999, priceline.com had the following outstanding warrants

REGISTRATION RIGHTS


    The holders of an aggregate of 144,983,503 shares of common stock or
securities convertible into common stock are entitled to certain registration
rights. After the offering, an aggregate of 142,104,432 shares of common stock
or securities convertible into common stock will continue to be entitled to
registration rights. These rights are provided under the terms of a registration
rights agreement between priceline.com and the holders of the registrable
securities, who include Mr. Braddock, Mr. Walker, Walker Digital, General
Atlantic, Vulcan Ventures Incorporated, other stockholders and several airlines.
This agreement provides demand registration rights to the holders of
substantially all of the registrable securities. In addition, the holders of all
of the registrable securities are entitled under the agreement, subject to
certain limitations, to require priceline.com to include their registrable
securities in future registration statements the company files. Registration of
shares of common stock pursuant to the rights granted in this agreement will
result in such shares becoming freely tradeable without restriction under the
Securities Act of 1933. All registration expenses incurred in connection with
the above registrations will be borne by priceline.com.


    The sale of shares of common stock by the selling stockholders in this
offering is being made pursuant to the "piggyback" registration rights contained
in the registration rights agreement. Priceline.com obtained from parties to the
registration rights agreement that hold shares (or presently exercisable
warrants to purchase shares) of common stock available for sale in this offering
a waiver of a 30-day notice period under the agreement and a consent to the
assignment of registration rights by Messrs. Jay Walker and Richard Braddock,
each of whom chose to sell less than his pro rata number of shares in this
offering. Priceline.com did not obtain such waiver and consent from certain
other parties to the registration rights agreement (comprised of certain airline
participants) because they do not have shares (or presently exercisable warrants
to purchase shares) of common stock available for sale in this offering.
Priceline.com believes that no damages arise as a result of the failure to
obtain such waiver and consent since such airline participants do not have
shares (or presently exercisable warrants to purchase shares) of common stock
available for sale. Nevertheless, if a disagreement with such airline
participants were to arise, priceline.com can not be certain as to the effect,
if any, that it could have on its relationship with such airline participants or
whether damages or other remedies could be imposed.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for the common stock is ChaseMellon
Shareholder Services, L.L.C.

LISTING

    The common stock is traded on the Nasdaq National Market under the trading
symbol "PCLN."

                        SHARES ELIGIBLE FOR FUTURE SALE

    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
146,782,296 shares of common stock. Of these shares, the 5,500,000 shares of
common stock sold in this offering, the 10,000,000 shares of common stock sold
in priceline.com's initial public offering and 938,540 shares of common stock
eligible to be sold by employees upon exercise of stock options pursuant to the
option exercise program will be freely tradeable without restriction under the
Securities Act unless purchased by "affiliates" of priceline.com as defined in
Rule 144 under the Securities Act. The shares of common stock issuable upon
conversion of the     % convertible subordinated notes sold in the concurrent
note offering will be freely tradeable in a similar manner. In addition,
26,582,391 shares are issuable upon exercise of outstanding options granted
under the 1997 Omnibus Plan and the 1999 Omnibus Plan. We have filed a
registration statement on Form S-8 covering the shares of common stock issuable
under such options. As a result, when the options are exercised, the shares
issued will be freely tradeable after September 25, 1999 under the Securities
Act unless purchased by "affiliates" of priceline.com as defined in Rule 144
under the Securities Act. The balance of priceline.com's outstanding shares of
common stock and the shares of common stock issuable upon exercise of
outstanding warrants will be "restricted securities" under the Securities Act,
subject to restrictions on the timing, manner and volume of sales of such

      provisions;



    - in the case of each selling stockholder, the sale or other transfers of
      any shares of common stock by certain of the foregoing persons to any

      the foregoing provisions; or



    - the grant of exchange rights and the issuance of our common stock on
      exercise of such exchange rights, in connection with the development by
      priceline.com of new lines of business through other entities, PROVIDED
      THAT no such issuance is permitted prior to 180 days after the date of
      this prospectus.


    In addition, holders who will own 3,547,311 shares of common stock after
this offering and options to purchase an additional 4,532,504 shares after this
offering agreed in connection with our initial public offering to similar
restrictions until after September 25, 1999.


    In connection with the option exercise program, holders of options to
purchase 9,676,356 shares of common stock registered on our Form S-8 entered
into lock-up agreements restricting the exercise of their options and sale of
the underlying shares until 180 days after the date of this prospectus, without
our prior written consent.


    After giving effect to these contractual restrictions and shares that may be
issued upon exercise of outstanding options and warrants, we estimate that
additional shares of common stock will be available for sale in the public
market as follows:

</TABLE>

Since many of these shares were purchased at prices substantially below current
market prices, we believe a significant number of these shares will be sold when
eligible for resale.

    In general, under Rule 144 as currently in effect, 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 1,400,000 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,

                                       96
<PAGE>
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.

    Upon consummation of this offering and subject to the foregoing lock-up
agreements, holders of up to 142,153,503 shares of common stock and securities
exercisable for shares of common stock will have certain rights to request the
registration of their shares under the Securities Act. Upon the effectiveness of
such registration, all shares covered by such registration statement would be
freely transferable. Walker Digital also owns directly approximately 5.2% of our
outstanding common stock. Walker Digital has established an option plan for its
officers and employees that provides for the grant of options to purchase common
stock held by Walker Digital. See "Description of Capital Stock--Registration
Rights."

</TABLE>

    The U.S. underwriters and the international underwriters are collectively
referred to as the "underwriters," and the U.S. representatives and the
international representatives are collectively referred to as the
"representatives." The underwriters are offering the shares of common stock
subject to their acceptance of the shares from priceline.com and the selling
stockholders and subject to prior sale. The underwriting agreement provides that
the obligations of the several underwriters to pay for and accept delivery of
the shares of common stock offered by this prospectus are subject to the
approval of certain legal matters by their counsel and to certain other
conditions. The underwriters are obligated to take and

                                       98
<PAGE>
pay for all of the shares of common stock offered by this prospectus if any such
shares are taken. However, the underwriters are not required to take or pay for
the shares covered by the underwriters over-allotment option described below.

    In the agreement between U.S. and international underwriters, sales may be
made between U.S. underwriters and international underwriters of any number of
shares as may be mutually agreed. The per share price of any shares sold by the
underwriters shall be the public offering price listed on the cover page of this
prospectus, in United States dollars, less an amount not greater than the per
share amount of the concession to dealers described below.

    The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price listed on the cover
page of this prospectus 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 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.

    The selling stockholders have 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 825,000 additional shares of common stock at the public offering
price listed on the cover page of this prospectus, less underwriting discounts
and commissions. The U.S. underwriters may exercise this option solely for the
purpose of covering overallotments, if any, made in connection with the offering
of the shares of common stock offered by this prospectus. To the extent the
option is exercised, each U.S. underwriter will become obligated, subject to
certain conditions, to purchase about the same percentage of the additional
shares of common stock as the number listed next to the U.S. underwriter's name
in the preceding table bears to the total number of shares of common stock
listed next to the names of all U.S. underwriters in the preceding table. If the
U.S. underwriters' option is exercised in full, the total price to the public
would be $               , the total underwriters' discounts and commissions
would be $               and the total proceeds to the selling stockholders
would be $         .


    Each of priceline.com, the selling stockholders and Mr. Jay S. Walker who,
after this offering, will own an aggregate of 147,835,331 shares of common
stock, including shares issuable upon exercises of options and warrants owned by
them, has agreed, subject to 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, 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;

    - as to selling stockholders that are parties to the registration rights
      agreement, 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; or

    - file a registration statement, other than, in the case of priceline.com, a
      registration statement (1) on Form S-8 covering shares of common stock
      subject to outstanding options or options to be issued under the 1997
      Omnibus Plan or the 1999 Omnibus Plan or (2) on any appropriate form in
      response to demand registration rights under the registration rights
      agreement.

    The restrictions described in this paragraph do not apply in certain
circumstances, including:

    - the sale of the shares to the underwriters in this offering;

                                       99
<PAGE>
    - the issuance of restricted stock awards under priceline.com's existing
      employee benefit plans or shares of common stock upon the exercise of an
      option or a warrant or the conversion of a security outstanding on the
      date of this prospectus;

    - the grant of options to certain officers, directors, employees or
      consultants provided such options are not exercisable prior to the end of
      the lock-up period;


    - the issuance of warrants (or shares of capital stock upon the exercise of
      such warrants) to suppliers or other entities providing products or
      services to priceline.com in connection with entering into certain supply,
      adaptive marketing or other similar arrangements, provided that the
      recipients of such warrants or shares agree to be bound by the foregoing
      provisions;



    - in the case of each selling stockholder, the sale or other transfers of
      any shares of common stock by certain of the foregoing persons to any
      associate of such selling stockholder, 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; or



    - the grant of exchange rights and the issuance of our common stock on
      exercise of such exchange rights, in connection with the development by
      priceline.com of new lines of business through other entities, PROVIDED
      THAT no such issuance is permitted prior to 180 days after the date of
      this prospectus.


    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, the selling stockholders and the underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.

    Priceline.com has entered into an adaptive marketing agreement with Discover
Financial Services, Inc. Discover Financial Services will pay priceline.com a
fee for qualifying credit applications and qualifying credit applications and
qualifying upgrades of existing Discover credit card accounts. Discover
Financial Services and Morgan Stanley & Co. Incorporated are both wholly owned
by Morgan Stanley Dean Witter & Co.

                          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

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. BUSINESS DESCRIPTION

    Priceline.com Incorporated (priceline.com) has pioneered a unique new type
of e-commerce known as a demand collection system that enables consumers to use
the Internet to save money on a wide range of products and services while
enabling sellers to generate incremental revenue. Using a simple and compelling
consumer proposition--name your price, priceline.com collects consumer demand,
in the form of individual customer offers guaranteed by a credit card, for a
particular product or service at a price set by the customer. Priceline.com then
either communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether the customer's
offer can be fulfilled on the basis of the pricing information and rules
established by the sellers. Consumers agree to hold their offers open for a
specified period of time and once fulfilled, offers cannot be canceled. By
requiring consumers to be flexible with respect to brands, sellers and/or
product features, priceline.com enables sellers to generate incremental revenue
without disrupting their existing distribution channels or retail pricing
structures. Priceline.com commenced its service on April 6, 1998 with the sale
of leisure airline tickets. During 1997, the Company had been in the development
stage. Priceline.com's services were expanded to include the sale of new
automobiles, on a test basis, in July 1998, hotel room reservations in October
1998, and home mortgages in January 1999.

    Priceline.com was founded as a limited liability company (LLC) in July 1997
and converted to a corporation in July 1998. All LLC units and options and
warrants to purchase units, were converted in July 1998 to common stock of
priceline.com (Common Stock) and options and warrants to purchase Common Stock.
For presentation purposes all such LLC units, and options and warrants to
purchase units are presented as Common Stock or options and warrants to purchase
Common Stock. Priceline Travel, Inc. (Priceline Travel) holds the travel agency
license used to effect airline ticket sales. Priceline Travel is wholly owned by
the founding stockholder and Vice-Chairman of priceline.com. Priceline.com has a
call option to purchase Priceline Travel for nominal consideration.
Priceline.com and Priceline Travel are entities under common control,
accordingly, the financial statements of the two companies are presented on a
combined basis. Priceline Travel will merge into priceline.com during the first
quarter of 1999. Priceline.com and Priceline Travel are referred to,
collectively, as the Company.

    Walker Digital Corporation (Walker Digital), a research and development
company, developed the priceline.com service and the business model and related
intellectual property rights underlying the priceline.com service, the rights
for which were transferred to the Company on July 18, 1997. Walker Digital had
no operations and no revenues related to the assets transferred to
priceline.com. Walker Digital was founded and is controlled by the founding
stockholder and Vice Chairman of priceline.com. Walker Digital has also been
providing the Company with a variety of services including subleasing office
facilities to the Company on a month to month basis. Charges to the Company for
such services aggregated $19,813 and $706,160 during the period July 18, 1997 to
December 31, 1997 and the year ended December 31, 1998, respectively. Such
amounts are included in general and administrative expense. In addition, the
Company charged Walker Digital $95,874 and $384,831 for the period July 18, 1997
to December 31, 1997 and the year ended December 31, 1998, respectively, for
shared expenses. Such reimbursement has been offset against general and
administrative expenses in the accompanying combined statements of operations.
Several of the Company's executive offers and other key employees are also
officers, employees and/or stockholders of Walker Digital.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    PRINCIPLES OF COMBINATION AND BASIS OF PRESENTATION--The combined financial
statements for all periods presented include the financial statements of
priceline.com and Priceline Travel. The combined financial

             PRICELINE.COM INCORPORATED AND PRICELINE TRAVEL, INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
statements have been prepared in accordance with generally accepted accounting
principles. All significant intercompany transactions have been eliminated.

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

    FAIR VALUE OF FINANCIAL INSTRUMENTS--The Company's financial instruments,
including cash and cash equivalents, restricted bank deposits, accounts
receivable-net and accounts payable, are carried at cost which approximates
their fair value because of the short-term maturity of these financial
instruments. The carrying value of the capital lease obligations and long-term
debt approximates fair value because the interest rates on these obligations are
comparable to the interest rates that could have been obtained at the date of
the balance sheet.

    CASH AND CASH EQUIVALENTS, RESTRICTED BANK DEPOSITS--The Company invests
excess cash primarily in money market accounts, certificates of deposits, and
short-term commercial paper. All highly liquid instruments with an original
maturity of three months or less are considered cash equivalents. Restricted
bank deposits collateralize letters of credit issued in favor of certain
airlines.

    NOTE RECEIVABLE FROM STOCKHOLDER--Represents a note receivable related to
the sale of common stock that was subsequently paid on January 9, 1998.

    PROPERTY AND EQUIPMENT--Property and equipment are stated at historical
cost. Depreciation and amortization of property and equipment is computed on a
straight-line basis, generally over the estimated useful lives of the assets or,
when applicable, the life of the lease, whichever is shorter. Capitalized
software costs represent costs paid to third parties and are amortized on a
straight-line basis over their estimated useful lives. Maintenance and repairs
are charged directly to expense as incurred.

    INTANGIBLE ASSETS--The Company acquired certain patent rights covering the
core buyer-driven commerce system and the method and system for pricing and
selling airline ticket options from a Walker Digital affiliate on July 18, 1997
in exchange for 6,895,833 shares of common stock. Since the transfer was between
entities under common control, it was recorded at the historical cost of the
asset transferred, which was zero.

    IMPAIRMENT OF LONG-LIVED ASSETS--The Company evaluates the recoverability of
its long-lived assets in accordance with Statement of Financial Accounting
Standards (SFAS) No. 121, Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to be Disposed of. SFAS No. 121 requires recognition of
impairment of long-lived assets in the event the net book value of such assets
exceeds the future undiscounted cash flows attributable to such assets.

    REVENUES AND COST OF REVENUES--The manner in which revenues are recognized
differs depending on the product or service sold through the priceline.com
service. With respect to airline ticket or hotel room reservation services,
revenues are generated by transactions with customers who make offers to
purchase airline tickets and hotel rooms supplied by participating sellers. All
offers are guaranteed by a customer credit card. Credit cards are the only form
of payment accepted by priceline.com. Revenues and related costs are recognized
if, and when, the Company accepts the customer's offer and charges the
customer's credit card. Because priceline.com is the merchant of record in these
transactions, revenue for these

                                      F-8

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
services includes the amount billed to the customer, net of certain
transportation taxes and fees. Airline and hotel revenues may be supplemented by
fees that are paid to the Company by third parties in connection with adaptive
marketing programs. With respect to automobile and mortgage services, fees or
other payments payable by the seller and/or the customer are recognized as
revenue. Because priceline.com acts as an intermediary between the customer and
the seller in these transactions, revenue for these products and services is
recorded at the amount of the fee received in connection with the transaction,
and not on the value of the underlying transaction, when the transaction is
completed. Automobile and mortgage services revenues may also include fees from
third parties for adaptive marketing programs.

    Revenues from adaptive marketing programs are earned when customers elect to
increase their offering price, and thus the likelihood of a successful
transaction, at no additional costs, by participating in a sponsor promotion.
Priceline.com earns fee income from the corporate sponsor of each adaptive
marketing program based primarily upon customer participation levels. During
1998, the Company generated approximately $4,037,000 of revenues from adaptive
marketing programs. All of these adaptive marketing revenues resulted from fees
paid to the Company by Capital One Bank in connection with a credit card
promotion--see Note 12.

    Priceline.com expressly permits only credit cards as an acceptable form of
payment from its consumers. Consequently, the Company believes that it does not
have a significant risk of loss with respect to customer transactions. On rare
occasions, the Company provides credit card refunds to individual customers to
satisfy disputes and complaints. The Company accrues for expected credit card
charge-backs and classifies the resulting expense as an addition to the
allowance for doubtful accounts. The Company extends customary payment terms to
corporate customers such as automobile dealers and adaptive marketing sponsors.
The Company did not experience any uncollectible corporate accounts receivable
in 1998.

    Cost of revenues includes product costs and the pro rata amount of the Delta
Warrant earned prior to the December 31, 1998 measurement date based on their
performance through that date--see Note 6.

    SUPPLIER START-UP WARRANT COSTS--Supplier start-up warrant costs includes
the value of warrants issued to secure certain airline alliances and
relationships including the value of the Delta Warrant net of the amount
included in cost of revenues--see Note 6.

    SALES AND MARKETING--Sales and marketing expenses are comprised primarily of
costs of radio and newspaper advertising, costs of the third-party offer-taking
call center, credit card processing fees, provisions for customer credit card
charge-backs and compensation for the Company's sales and marketing personnel.
All sales and marketing costs are expensed as incurred.

    SYSTEMS AND BUSINESS DEVELOPMENT--Systems and business development expenses
are comprised primarily of compensation to the Company's information systems and
product development staff and payments to outside contractors, data
communications and other expenses associated with operating the Company's Web
site, depreciation on computer hardware and licensing fees for computer
software. Such costs are expensed as incurred.

    INTEREST INCOME (EXPENSE), NET--Interest income (expense), net includes
interest income of $523 and $633,294 and interest expense of $835 and $84,920
for the period July 18, 1997 to December 31, 1997 and the year ended December
31, 1998, respectively.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    EQUITY-BASED COMPENSATION--The Company accounts for stock-based employee
compensation arrangements in accordance with provisions of Accounting Principles
Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and
complies with the disclosure provisions of SFAS No. 123, Accounting for
Stock-Based Compensation. Under APB Opinion No. 25, compensation expense is
based on the difference, if any, on the date of grant, between the fair value of
priceline.com's stock and the exercise price.

    The Company accounts for equity instruments issued to non-employees in
accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force
("EITF") Issue No. 96-18, Accounting for Equity Instruments That Are Issued to
Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or
Services. All transactions in which goods or services are the consideration
received for the issuance of equity instruments are accounted for based on the
fair value of the consideration received or the fair value of the equity
instrument issued, whichever is more reliably measurable. The measurement date
of the fair value of the equity instrument issued is the earlier of the date on
which the counterparty's performance is complete or the date on which it is
probable that performance will occur.

    INCOME TAXES--The Company accounts for income taxes in accordance with SFAS
No. 109, Accounting for Income Taxes, which requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
temporary difference between the financial statement and tax basis of assets and
liabilities using presently enacted tax rates in effect. Valuation allowances
are established when necessary to reduce deferred tax assets to the amounts
expected to be realized.

    During the period that priceline.com operated as an LLC, it was treated
substantially as a partnership for tax purposes and, accordingly, the tax effect
of its activities accrued to its members through July 1998.

    NET LOSS PER SHARE--The Company computes net loss per share in accordance
with SFAS No. 128, Earnings Per Share which requires dual presentation of basic
earnings per share ("EPS") and diluted EPS.

    Basic earnings per share is computed using the weighted average number of
common shares outstanding during the period. Diluted earnings per share is
computed using the weighted average number of common shares and potentially
dilutive shares outstanding during the period. Potential common shares consist
of the incremental common shares issuable upon conversion of the Series A and
Series B Convertible Preferred Stock (using the if-converted method) and shares
issuable upon the exercise of stock options and warrants (using the treasury
stock method). At December 31, 1998, Series A and Series B Convertible Preferred
Stock were convertible into 21,610,854 shares and 17,296,874 shares,
respectively, and options and warrants to purchase 42,181,997 shares of Common
Stock were outstanding. Outstanding convertible preferred stock, warrants and
options could potentially dilute basic earnings per share in the future but have
not been included in the computation of diluted net loss per share as the impact
would have been antidilutive for the periods presented.

    BUSINESS RISK--Business risks include the following:

    Competition--The markets for the products and services offered on the
priceline.com service are intensely competitive. The Company competes with both
traditional distribution channels and online services. The Company currently or
potentially competes with a variety of companies with respect to each product or
services offered. The Company potentially faces competition from a number of
large online services that have expertise in developing online commerce and in
facilitating Internet traffic. Many

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
competitors have significant competitive advantages. For example, airlines,
hotels and other suppliers also sell their products and services directly to
consumers and have established Web sites. Internet directories, search engines
and large traditional retailers have significantly greater operating histories,
customer bases, technical expertise, brand recognition and/or online commerce
experience than the Company. In addition, certain competitors may be able to
devote significantly greater resources to furthering their business.

    Dependence on Airline Industry and Certain Carriers--The Company's near
term, and possibly long term, prospects are significantly dependent upon the
sale of leisure airline tickets. Sales of leisure airline tickets and revenues
derived from related adaptive marketing programs represented essentially all of
the Company's revenues for the year ended December 31, 1998. Sales of airline
tickets from the Company's three largest airline suppliers accounted for
approximately 95% of airline ticket revenue for the year ended December 31,
1998. As a result, currently the Company is substantially dependent upon the
continued participation of these three airlines in the priceline.com service in
order to maintain and continue to grow its total airline ticket revenues.
Significantly reducing the Company's dependence on the airlines is likely to
take a long time and there can be no guarantee that the Company will succeed in
reducing that dependence.

    Risks Associated with Brand Development--The Company intends to continue to
pursue an aggressive brand-enhancement strategy, which will include mass market
and multimedia advertising, promotional programs and public relations
activities. To increase awareness of the priceline.com brand and expand it to a
wide range of products and services, the Company will need to continue to spend
significant amounts on advertising and promotions. These expenditures may not
result in a sufficient increase in revenues to cover such advertising and
promotions expenses.

    CONCENTRATION OF CREDIT RISK--Financial instruments which potentially
subject the Company to concentrations of credit risk are principally bank
deposits and accounts receivable. Cash and cash equivalents and restricted bank
deposits are deposited with high credit quality financial institutions. Accounts
receivable typically represent credit card purchases and are derived from the
revenues earned from customers in the U.S. and are denominated in U.S. dollars.
Accounts receivable balances are typically settled through customer credit cards
and, as a result, the majority of accounts receivable are collected upon
processing of credit card transactions. The Company maintains an allowance for
uncollectible accounts based upon the expected collectibility of accounts
receivable. During the year ended December 31, 1998, approximately 11% of
revenues were generated from one vendor participating in an adaptive marketing
program. As of December 31, 1998, amounts due from this vendor represented
approximately 54% of accounts receivable.

    COMPREHENSIVE INCOME--Effective January 1, 1998, the Company adopted SFAS
No. 130, Reporting Comprehensive Income. Under SFAS 130 changes in net assets of
an entity resulting from transactions and other events and circumstances from
non-owner sources are reported in a financial statement for the period in which
they are recognized. Because there were no such changes, adoption of SFAS 130
did not impact the combined financial statements of the Company.

    SEGMENT REPORTING--Effective January 1, 1998, the Company adopted SFAS No.
131, Disclosures About Segments of an Enterprise and Related Information. The
Company operates as a single segment and will evaluate additional segment
disclosure requirements as it expands its operations.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, Statement of Financial Accounting Standards SFAS No 133
Accounting for Derivative Instruments and Hedging Activities was released. The
statement requires the recognition of all derivatives as either assets or
liabilities in the balance sheet and the measurement of those instruments at
fair value. The accounting for changes in the fair value of a derivative depends
on the planned use of the derivative and the resulting designation. The Company
is required to implement the statement in the first quarter of fiscal 2000. The
Company has not used derivative instruments and believes the impact of adoption
of this statement will not have a significant effect on the financial
statements.

    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 98-1, Accounting for Costs of Computer Software
Developed or Obtained for Internal Use. This SOP is effective for fiscal years
beginning after December 15, 1998. This SOP requires capitalization of certain
costs of computer software developed or obtained for internal use.

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

    On July 18, 1997, priceline.com issued 42,990,211 shares of Common Stock for
the initial contributed services of the founders. No compensation expense was
recognized for the contributed services as priceline.com was in the earliest
phases of development. Such services included conceiving the priceline.com
business model, developing business strategies and operating plans, initiating
contact with airline suppliers and raising capital. There were no employment
agreements related to the services initially contributed and/or the shares
issued in respect of such shares.

    Also, on July 18, 1997, priceline.com issued 6,895,833 shares of Common
Stock to Walker Digital in exchange for the transfer by Walker Digital to
priceline.com all of the rights, title, and interest in certain patents and
patent applications relating to buyer driven commerce.

    In July 1998, priceline.com also issued 8,125,000 shares of Common Stock, to
the Chairman and Chief Executive Officer which resulted in the recognition of a
one time charge of $6,500,000 with respect to these shares. The shares were
issued as compensation for agreeing to accept the position.

    In July 1998, pursuant to an agreement between priceline.com and two
partnerships affiliated with General Atlantic Partners, LP (collectively GAP),
priceline.com sold to GAP a total of 17,288,684 shares of

6. STOCKHOLDERS' EQUITY (CONTINUED)
Series A Convertible Preferred Stock, par value $0.01 per share (the Series A
Preferred Stock) for $20,000,000.

    In December 1998, priceline.com raised net proceeds of approximately
$54,414,550 by completing a private placement of an aggregate of 13,837,500
shares of its Series B Convertible Preferred Stock (the Series B Preferred
Stock) with several investors, including GAP and Vulcan Ventures Incorporated.
Fees of $850,000 have been paid to a company, in which a director of
priceline.com is a director and stockholder, in connection with this
transaction.

    Shares of the Series A and Series B Preferred Stock are automatically
convertible, subject to antidilution adjustment, into an equal number of shares
of Common Stock upon an initial public offering of the Company. The holders of
the Series A and Series B Preferred Stock vote together as a single class with
the holders of Common Stock. If the Company has not consummated an initial
public offering by December 1999, the conversion price of Series B Preferred
Stock will be adjusted to $1.97 per share. Since the Series B Preferred Stock
contained this beneficial conversion feature at the date of issue, the Company
allocated a portion of the proceeds equal to the value of the feature,
$34,650,000, to additional paid-in capital. This amount will be amortized over
one year. Amortization will cease if an initial public offering is completed
within one year and the Series B Preferred Stock convert at $3.20 per share. The
shares of the Series A and Series B Preferred Stock rank senior to the Common
Stock with respect to liquidation and equal to the Common Stock with respect to
dividends.

    In April 1998, priceline.com issued warrants to purchase 125,000 shares of
Common Stock, at a zero exercise price, to a non-employee in exchange for
services rendered to the Company. The estimated fair value of the warrants at
the date of grant of $100,000 was based on the value of the equivalent shares as
of the grant date, that is 125,000 shares at $0.80 per share, and has been
reflected as sales and marketing expense and additional paid-in-capital.

    In April 1998, priceline.com issued warrants to purchase 62,500 shares of
Common Stock at an exercise price of $0.80 per share in conjunction with a
promissory note (see Note 5--Long-Term Debt).

    In August 1998, priceline.com entered into a warrant agreement with Delta
Air Lines (Delta) to purchase up to 18,892,603 shares of Common Stock at an
exercise price of approximately $0.93 per share (Delta Warrant) for agreeing to
participate in the priceline.com service. Vesting was contingent upon
achievement of certain predetermined performance thresholds. However, there was
no penalty for failure to provide ticket inventory to satisfy these performance
thresholds. Accordingly, no expense was recorded when the warrant was issued. On
December 31, 1998, the Company amended its agreement with Delta to eliminate the
vesting contingencies and fix the number of shares subject to the warrant at
18,619,402. The warrants were immediately vested on the date of grant, in that
they are not subject to any forfeiture for any reason. The amended Delta Warrant
will become exercisable at the earlier of seven years or over three years upon
the achievement of certain performance thresholds. The agreement does not
require Delta to make any performance commitments, is non-exclusive and allows
Delta to participate in other programs similar to the priceline.com service.
Accordingly, the Company recognized approximately $58.7 million of expense based
upon the fair value of the warrant on December 31, 1998, of which $3 million is
included in cost of revenues-supplier warrant costs and $55.7 million is
included in expenses-supplier start-up warrant costs in the accompanying
statement of operations.

    On December 31, 1998, priceline.com issued warrants to purchase 937,500
shares of Common Stock at an exercise price of $3.20 per share to three airlines
in recognition of their being among the original

participants in the priceline.com service. Because there are no requirements as
to the nature or length of that participation and the warrants are not subject
to forfeiture for any reason, the Company recognized approximately $2.3 million
of expense based upon the fair value of the warrants at December 31, 1998, which
is included in expenses-supplier start-up warrant costs in the accompanying
statement of operations.

    On January 29, 1999, priceline.com issued warrants to an airline to purchase
1,250,000 shares of Common Stock at an exercise price of $6.40 per share. The
warrants become exercisable as follows, 50% on January 29, 2000 and 50% on
January 29, 2001. The agreement requires the airline to make available to
priceline.com airline ticket inventory on certain specified terms and conditions
for two years. If the airline does not provide the specified airline ticket
inventory, the unexercised warrants are returnable and in addition, there is a
penalty of $1.0 million in the first year and $0.5 million in the second year.
The fair value of the warrant of $3.1 million at the grant date was capitalized
and will be amortized over the two year period during which services will be
provided to the Company.

    The fair value of the airline warrants was based on a third party valuation
using an option pricing model and the following assumptions:

7. STOCK OPTION PLAN

    Priceline.com has adopted the 1997 Omnibus Plan (the Plan), which provides
for grants of options as incentives and rewards to encourage employees,
officers, consultants and directors in the long term success of the Company. The
Plan provides for grants of options to purchase up to 23,875,000 shares at a
purchase price equal to the fair market value on the date of grant. Generally,
the options vest over three years from the date of grant. In accounting for the
Plan, the Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options. When the exercise price of employee
stock options issued under the plan equaled the fair value of the underlying
stock on the date of grant, no compensation expense was recorded. Compensation
expense was recognized for the fair value of the options granted to
non-employees and to the extent fair value of the underlying stock exceeded the
exercise price of employee stock options. Compensation expense, included in
general and administrative, recognized during the year ended December 31, 1998
aggregated $245,063.

    The fair value of each option grant was determined on the date of grant
using the minimum value method. The weighted average fair value of options
granted during 1998 was estimated to be approximately $0.15 on the dates of
grant using the minimum value method and the following assumptions: volatility
of 0%, risk free interest rate of 6.00% and an expected life of 3 years,
respectively. The Plan also provides for the grant of tandem stock appreciation
rights, stand-alone stock appreciation rights, phantom stock and other forms of
equity based incentive awards which do not reduce the number of shares with
respect to which incentive awards may be granted. No such awards were made as of
December 31, 1998.

    In February 1999, priceline.com established the 1999 Omnibus Plan (the 1999
Plan), which provides for grants of options as incentives and rewards to
encourage employees, officers, consultants and directors in the long term
success of the Company. The Plan provides for grants of options to purchase up
to 9,375,000 shares at a purchase price equal to the fair market value on the
date of grant. Generally, the options vest over three years from the date of
grant. The Plan also provides for the grant of tandem stock appreciation rights,
stand-alone stock appreciation rights, phantom stock and other forms of equity
based incentive awards which do not reduce the number of shares with respect to
which incentive awards may be granted.

8. TAXES

    INCOME TAXES--Through July 31, 1998, priceline.com operated as a limited
liability company and income taxes (benefits) accrued to the members.
Accordingly, no income taxes (benefits) were reflected in the accompanying
financial statements as of December 31, 1997 and for the period then ended.
Since converting from an LLC to a corporation in July 1998, the Company has
incurred net operating losses of $22,703,000. This loss will expire if not
utilized by December 31, 2018. As of December 31, 1998 a valuation allowance for
the full amount of the net deferred tax asset of approximately $37,985,023,
resulting from the tax net operating losses and other items was recorded because
of the uncertainty regarding its realization.

    FEDERAL AIR TRANSPORTATION TAX--Currently, a Federal transportation tax is
imposed upon the sale of airline tickets and generally is collected by the
airlines selling the tickets. The tax is based upon a percentage of the cost of
transportation, which was 9% for periods prior to October 1, 1998 and 8%
thereafter. The tax has been calculated based on the amount paid to the airline
for a ticket, rather than the price paid by the customer. There is a possibility
that current law requires computation of the tax based on the price paid by the
customer. Approximately $111,000 in additional taxes relating to the method of
calculating the tax has been accrued as of December 31, 1998.

9. OTHER RELATED PARTY TRANSACTIONS

    The Founder and Vice Chairman of priceline.com also serves as non-executive
Chairman of NewSub Services, Inc. (NewSub), a direct marketing company
co-founded by him. The Company participates in certain adaptive marketing
programs with NewSub. Sales and marketing expense related to these programs
totaled $80,799 for the year ended December 31, 1998. There was no such expense
in 1997.

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

10. COMMITMENTS AND CONTINGENCIES

    LEGAL PROCEEDINGS--On January 6, 1999, priceline.com received notice that a
third party patent applicant and patent attorney, Thomas G. Woolston,
purportedly had filed in December 1998 with the United States

                                      F-17
<PAGE>
             PRICELINE.COM INCORPORATED AND PRICELINE TRAVEL, INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)
Patent and Trademark Office a request to declare an interference between a
patent application filed by Woolston describing an electronic market for used
and collectible goods and priceline.com's core buyer-driven commerce patent.
Priceline.com has received a copy of a Petition for Interference from Woolston,
the named inventor of at least three United States Patent applications titled
Consignment Nodes, one of which has issued as a patent. Priceline.com currently
is awaiting information from the Patent Office regarding whether it will
initiate an interference proceeding concerning Woolston's patent application and
priceline.com's core buyer-driven commerce patent. An interference is an
administrative proceeding instituted in the Patent Office to determine questions
of patentability and priority of invention between two or more parties claiming
the same patentable invention. There is no statutory period within which the
Patent Office must act on an interference request. If an interference is
declared and proceeds through a final hearing in the Patent Office, a final
judgment is made by the Patent Office as to inventorship. Following such final
judgment, appeals could be made in Federal court. While there can be no
certainty as to time periods, interference proceedings typically take years to
resolve.

    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from the
priceline.com core buyer-driven commerce patent. In order to make this showing,
he would have to prove, among other things, that he invented the subject matter
of the priceline.com claims before the inventors of the priceline.com patent. If
the Patent Office were to find that Woolston's patent application supported the
copied priceline.com claims, it would resolve the interference by awarding
inventorship to the party with the earliest proven date of invention. Woolston
recently announced an agreement to license his issued patent and pending patent
applications to the owner of an Internet travel service that, according to such
announcement, commenced on-line operations in the fourth quarter of 1998 and
purports to compete with priceline.com.

    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While Woolston claims to have an earlier
invention date by a period of approximately sixteen months, the final decision
as to priority of invention would be made by the Patent Office after considering
facts provided by each party during the interference proceeding. If an
interference is declared and thereafter resolved in favor of Woolston, such
resolution could result in an award of some or all of the disputed patent claims
to Woolston. If, following such award, Woolston were successful in a patent
infringement action against priceline.com, including prevailing over all
defenses available to priceline.com such as those of non-infringement and
invalidity, this could require priceline.com to obtain licenses from Woolston at
a cost which could significantly adversely affect priceline.com's business. If
Woolston prevailed in both an interference and an infringement action, then
priceline.com could be enjoined from conducting business through the
priceline.com service to the extent covered by the patent claims awarded to
Woolston. In addition, defense of the interference action may be expensive and
may divert management attention away from priceline.com's business.

    On January 19, 1999, Marketel International Inc. (Marketel), a California
corporation, filed a lawsuit against priceline.com and Priceline Travel, among
others. On February 22, 1999, Marketel filed an amended and supplemental
complaint. The amended complaint filed by Marketel alleges causes of action for,
among other things, misappropriation of trade secrets, breach of contract,
conversion, breach of confidential relationship, copyright infringement, fraud,
unfair competition and false advertising, and seeks injunctive relief and
damages in an unspecified amount. In its amended complaint, Marketel alleges,

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

among other things, that the defendants conspired to misappropriate Marketel's
business model, which it describes as a buyer-driven electronic marketplace for
travel services and its appurtenant techniques, market research, forms, plans,
and processes, which allegedly were provided in confidence approximately ten
years ago. The amended complaint also alleges that three former Marketel
employees are the actual sole inventors or co-inventors of a patent which was
issued on August 11, 1998 and which patent has been assigned to priceline.com.
Marketel asks that the patent's inventorship be corrected accordingly.

    Based upon publicly available information, priceline.com believes that
Marketel's fax and fee-based business was launched in 1991 and ceased operations
seven months later. Priceline.com's Internet-based model was independently
developed by Walker Digital and priceline.com, and practiced by the Company
starting in 1998. Based on publicly available information and Marketel's
complaint, priceline.com understands that Marketel operated a fax-based travel
information service which offered consumers, travel agents and/or consolidators
the opportunity to purchase specially printed forms. These forms, when
accompanied by an additional non-refundable fee, allowed prospective ticket
buyers to fax to Marketel credit-card guaranteed bids for airline travel at a
bid price specified by the buyer. The Company believes that Marketel has not
engaged in any regular commercial activities since ceasing operations in 1992.
Based upon publicly available information, Marketel reactivated its active
status as a corporation by satisfying its back-due tax obligations to the State
of California shortly after the filing of its complaint.

    On February 5, and February 10, 1999, the Company filed their answer and
amended answer, respectively, to the amended complaint, in which they denied the
material allegations of liability in the complaint. Priceline.com and all other
defendants strongly dispute the material legal and factual allegations contained
in Marketel's amended complaint and believe that the amended complaint is
without merit. Priceline.com intends to defend vigorously against the action.
Defending the lawsuit may involve significant expense and, due to the inherent
uncertainties of litigation, there can be no certainty as to the ultimate
outcome. Pursuant to the indemnification obligations contained in the Purchase
and Intercompany Services Agreement with Walker Digital, Walker Digital has
agreed to indemnify, defend and hold harmless priceline.com for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.

    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.

    Priceline.com adopted a defined contribution 401(k) savings plan (the Plan)
during 1998 covering all employees who are at least 21 years old and have
completed 6 months of service. The Plan allows eligible employees to contribute
up to 20% of their eligible earnings, subject to a statutorily prescribed annual
limit. The Company may make matching contributions on a discretionary basis to
the Plan. All participants are fully vested in their contributions and
investment earnings. During the year ended December 31, 1998, the Company did
not make any matching contributions to the Plan.

12. SUBSEQUENT EVENTS

    On March 25, 1999, the Company obtained shareholder approval of a 1.25 for 1
stock split of its common stock and an increase in the authorized shares of its
common stock to 1,000,000,000 shares. In conjunction with the stock split the
par value of the common stock was reduced from $.01 per share to $.008 per
share. All share and per share data have been retroactively adjusted to reflect
the stock split.

    On March 24, 1999, priceline.com exercised its call option to purchase
Priceline Travel for nominal consideration and Priceline Travel was merged into
priceline.com.

    On March 3, 1999, Capital One Bank notified the Company of its termination
of its adaptive marketing program effective May 1, 1999.

13. RESTATEMENT

    Subsequent to the issuance of the Company's combined 1998 financial
statements, the Company's management determined that the calculation of the fair
value of the Delta warrant, other airline warrants and the beneficial conversion
feature on the Series B Preferred Stock should be revised. The fair value of the
Delta warrant and the other airline warrants has been revised to reflect the
change in the volatility assumption from 50% to 132%, eliminate the large block
and lack of marketability discounts, and consider

the warrant's anti-dilution and exercisability features. As a result, the 1998
combined financial statements have been restated from the amounts previously
reported to recognize an additional $22.0 million of expense based upon the
revised fair value of the warrants at December 31, 1998, of which $3.0 million
is included in the cost of revenues-supplier warrant costs and $19.0 million is
included in expenses-supplier start-up warrant costs. In addition, the value of
the beneficial conversion feature on the Series B Preferred Stock has been
revised to calculate such amount based on 22,500,000 shares. As a result,
additional paid-in capital and accumulated deficit have been restated from
amounts previously reported to recognize an additional $883,424 of accretion of
preferred stock based on the revalued beneficial conversion feature.

    A summary of the significant effects of the restatement is as follows:

1. BUSINESS DESCRIPTION

    Priceline.com Incorporated ("priceline.com") has pioneered a 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. Priceline.com collects consumer demand,
in the form of individual customer offers guaranteed by a credit card for a
particular product or service at a price set by the customer. Priceline.com then
either communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether the customer's
offer can be fulfilled on the basis of the pricing information and rules
established by the sellers. Consumers agree to hold their offers open for a
specified period of time and once fulfilled, offers cannot be cancelled. 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 Travel, Inc. ("Priceline Travel") previously held the travel
agency license used to effect airline ticket sales through the priceline.com
service. Priceline Travel was wholly owned by the founding stockholder of
priceline.com and on March 24, 1999, Priceline Travel was merged into
priceline.com for nominal consideration. The accompanying condensed financial
statements include the financial position and results of operations of Priceline
Travel for all periods presented.

2. BASIS OF PRESENTATION

    The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all
adjustments, consisting of normal recurring accruals considered necessary for a
fair presentation, have been included in the accompanying unaudited financial
statements. Operating results for the six months ended June 30, 1999 are not
necessarily indicative of the results that may be expected for the full year
ending December 31, 1999.

3. INITIAL PUBLIC OFFERING OF COMMON STOCK


    On April 1, 1999, priceline.com completed an initial public offering in
which it sold 10,000,000 shares of its common stock at a price of $16.00 per
share, raising $160.0 million in gross proceeds. Offering proceeds to
priceline.com, net of approximately $11.2 million in aggregate underwriters
discounts and commissions and $4.4 million in related expenses, were
approximately $144.4 million. Simultaneous with the effectiveness on March 29,
1999 of priceline.com's Registration Statement on Form S-1, each outstanding
share of priceline.com's Series A and Series B convertible preferred stock was
automatically converted into shares of common stock. As of June 30, 1999,
approximately 142.3 million shares of common stock were outstanding.


4. NET LOSS PER SHARE

    Priceline.com computes net loss per share in accordance with Statement of
Financial Accounting Standards 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

              NOTES TO CONDENSED FINANCIAL STATEMENTS (CONTINUED)

4. NET LOSS PER SHARE (CONTINUED)
of common shares and potentially dilutive shares outstanding during the period.
The effect of the conversion of the Series A and Series B convertible preferred
stock is included in the weighted average number of shares outstanding during
the period that commenced on the conversion date, March 29, 1999. The effect of
the preferred stock conversion for the period prior to March 29, 1999 has not
been included in the computation of diluted net loss per share as the impact
would have been antidilutive for the periods presented. Potential common shares
consist of the incremental common shares issuable upon the exercise of stock
options and warrants. At June 30, 1999, options and warrants to purchase
48,228,959 shares of common stock were outstanding. Outstanding 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.

    Net loss applicable to common stockholders for the six month period ended
June 30, 1999 was $39.8 million including a non-recurring, non-cash charge
associated with the accretion on the Series B convertible preferred stock that
was outstanding during such period of $8.4 million. Based on the weighted
average number of 137.4 million shares of common stock outstanding during the
six month period ended June 30, 1999, the per share basic and diluted net loss
applicable to common stockholders was $0.29.

5. RECENT ACCOUNTING PRONOUNCEMENTS

    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 requires capitalization of
certain costs of computer software developed or obtained for internal use.
Priceline.com adopted this SOP on January 1, 1999 and for the six month period
ended June 30, 1999, priceline.com capitalized approximately $5.7 million of
computer software developed or obtained for internal use. Amortization of such
costs aggregated approximately $149,000 during the six month period ended June
30, 1999.

6. COMMITMENTS AND CONTINGENCIES

    On January 6, 1999, priceline.com received notice that a third party patent
applicant and patent attorney, Thomas G. Woolston, purportedly had filed in
December 1998 with the United States Patent and Trademark Office a request to
declare an "interference" between a patent application filed by Woolston
describing an electronic market for used and collectible goods and
priceline.com's core buyer-driven commerce patent. Priceline.com has received a
copy of a Petition for Interference from Woolston, the named inventor of at
least three United States Patent applications titled "Consignment Nodes," one of
which has issued as a patent. Priceline.com currently is awaiting information
from the Patent Office regarding whether it will initiate an interference
proceeding concerning Woolston's patent application and priceline.com's core
buyer-driven commerce patent.

    Woolston recently announced an agreement to license his issued patent and
pending patent applications to the owner of a competing Internet travel service.

    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While Woolston claims to have an earlier
invention date by a period of approximately sixteen months, the final decision
as to priority of invention would be made by the Patent Office after considering
facts provided by

6. COMMITMENTS AND CONTINGENCIES (CONTINUED)
each party during the interference proceeding. If an interference is declared
and thereafter resolved in favor of Woolston, such resolution could result in an
award of some or all of the disputed patent claims to Woolston. If, following
such award, Woolston were successful in a patent infringement action against
priceline.com, including prevailing over all defenses available to priceline.com
such as those of non-infringement and invalidity, this could require
priceline.com to obtain licenses from Woolston at a cost which could
significantly adversely affect priceline.com's business. If Woolston prevailed
in both an interference and an infringement action, then priceline.com could be
enjoined from conducting business through the priceline.com service to the
extent covered by the patent claims awarded to Woolston. In addition, defense of
the interference action may be expensive and may divert management attention
away from priceline.com's business.

    On January 19, 1999, Marketel International Inc. ("Marketel"), a California
corporation, filed a lawsuit against priceline.com and Priceline Travel, among
others. On February 22, 1999, Marketel filed an amended and supplemental
complaint, and on March 17, 1999, Marketel filed a second amended complaint. The
second amended complaint filed by Marketel alleges causes of action for, among
other things, misappropriation of trade secrets, breach of contract, conversion,
breach of confidential relationship, copyright infringement, fraud, unfair
competition and false advertising, and seeks injunctive relief and damages in an
unspecified amount. In its second amended complaint, Marketel alleges, among
other things, that the defendants conspired to misappropriate Marketel's
business model, which it describes as a buyer-driven electronic marketplace for
travel services and its appurtenant techniques, market research, forms, plans,
and processes, which allegedly were provided in confidence to some of the
defendants approximately ten years ago. The second amended complaint also
alleges that three former Marketel employees are the actual sole inventors or
co-inventors of a patent which was issued on August 11, 1998 and which patent
has been assigned to priceline.com. Marketel asks that the patent's inventorship
be corrected accordingly.

    On February 5, 1999, February 10, 1999 and March 31, 1999, the defendants
filed their answer, amended answer and answer to the second amended complaint,
respectively in which they denied the material allegations of liability in the
complaints. Priceline.com and all other defendants strongly dispute the material
legal and factual allegations contained in Marketel's second amended complaint
and believe that the second amended complaint is without merit. Since May 28,
1999, there has been a discovery stay in effect, which was caused by the
withdrawal of Marketel's counsel. Marketel has retained new counsel, and the
priceline.com now anticipates moving forward with discovery.

    Defending the Marketel litigation may involve significant expense and, due
to the inherent uncertainties of litigation, there can be no certainty as to the
ultimate outcome. Pursuant to the indemnification obligations contained in the
Purchase and Intercompany Services Agreement with Walker Digital, Walker Digital
has agreed to indemnify, defend and hold harmless priceline.com for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.

    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. Such claims, even if not meritorious, could result in the expenditure of
significant financial and managerial resources.

7. SUBSEQUENT EVENTS


        COMMON STOCK AND CONVERTIBLE DEBT OFFERINGS.  On July 23, 1999,
    priceline.com filed a registration statement covering the sale of up to
    $287.5 million of convertible subordinated notes (including $37.5 million in
    respect of an underwriters' over-allotment option) and up to 6.325 million
    shares of common stock (including 825,000 shares in respect of an
    underwriters' over-allotment option). The common stock offering is to be
    comprised of 2.0 million shares of common stock to be issued and sold by
    priceline.com and 3.5 million shares to be sold by certain selling
    stockholders, plus the sale by the selling stockholders of any additional
    shares sold upon exercise of the underwriters' over-allotment option.



        OPTION EXERCISE PROGRAM.  On July 19, 1999, an option exercise program
    was established to enable employees employed as of June 1, 1999 to exercise
    options and sell shares through a cashless exercise program administered
    through a broker dealer. Priceline.com employees holding 938,540 options
    that were vested as of June 1, 1999 were permitted during the period
    commencing on July 20, 1999 and ending on July 30, 1999, to exercise a
    portion of their options that otherwise were not exercisable until September
    26, 1999 (following expiration of the 180 day initial public offering
    lock-up period) and to sell the underlying option shares through the
    program. Any employee who elected to exercise options and sell option shares
    pursuant to the option exercise program was required to agree to enter into
    a "lock-up" agreement in a form similar to that signed by selling
    stockholders in the secondary common stock offering, which prohibits
    additional option exercises or stock sales prior to 180 days from the
    completion of the secondary common stock offering.


        CONTINENTAL AIRLINES AGREEMENTS.  Continental Airlines agreed to join
    the priceline.com service on July 20, 1999 pursuant to the terms of an
    Airline Participation Agreement with priceline.com. Upon execution of the
    Airline Participation Agreement, priceline.com issued a warrant to
    Continental for the purchase of 1 million shares of common stock at an
    exercise price of $97.41 per share. The warrant will become exercisable upon
    the earlier of July 2004 or the achievement of certain performance
    thresholds. However the agreement does not require Continental to make any
    performance commitments. Priceline.com will incur a non-cash charge of
    approximately $90 million during the quarter ending September 30, 1999,
    reflecting the fair value of the Continental warrant at the grant date.

                               PROSPECTUS SUMMARY

    Priceline.com has pioneered a unique e-commerce pricing system known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price"--we collect consumer demand, in the form of
individual customer offers guaranteed by a credit card, for a particular product
or service at a price set by the customer. We then either communicate that
demand directly to participating sellers, or access participating sellers'
private databases to determine whether we can fulfill the customer's offer on
the basis of the pricing information and rules established by the sellers.
Consumers agree to hold their offers open for a specified period of time and,
once fulfilled, offers cannot be canceled. By requiring consumers to be flexible
with respect to brands, sellers and/or product features, we enable sellers to
generate incremental revenue without disrupting their existing distribution
channels or retail pricing structures.

    We commenced the priceline.com service on April 6, 1998 with the sale of
leisure airline tickets. Since that time, our business has grown significantly
and the priceline.com service now includes the following products and services:

    - leisure airline tickets, provided by six domestic and 16 international
      airline participants;

    - new automobiles, which was launched on a test basis in the New York
      metropolitan area in July 1998;

    - hotel room reservations, which was launched in October 1998, offers hotel
      rooms in substantially all major United States markets and includes as
      participants more than 10 leading national hotel chains; and

    - home financing services, which was launched in January 1999 with home
      mortgage services and now also includes home equity loans and refinancing
      services.

Through the innovative use of "adaptive marketing programs," we also market
customer acquisition programs for third parties. These programs facilitate the
completion of a higher percentage of successful transactions through the
priceline.com service while generating fee income for us.

    We generate revenues in a variety of ways depending on the product or
service sold. With respect to our airline ticket and hotel room reservation
services, we recognize as revenue the customer's named price, net of taxes, and
record as the cost of revenue the fare or rate charged by the seller. With
respect to our automobile service, we earn a fixed fee from both the customer
and the seller after the transaction is consummated. With respect to our home
financing service, we receive marketing fees equal to a percentage of the net
revenue generated by the service, which is operated in conjunction with
LendingTree, Inc. With respect to our adaptive marketing programs, we recognize
as revenue the fees due to us from our adaptive marketing partners.

    We believe that the priceline.com service already has achieved significant
consumer acceptance and widespread brand awareness. During the period from
launch through June 30, 1999, we collected guaranteed offers for approximately
5.1 million airline tickets, representing approximately $1.1 billion in total
consumer demand. This demand resulted in sales of approximately 762,000 airline
tickets, representing approximately $165.2 million in revenue. We intend to
continue to leverage the priceline.com brand by expanding our product offerings
to include other leisure travel products and other financial services products
and by expanding our new car sales service to the entire U.S. market. We also
are exploring expansion of our core "name your price" business model to other
areas of e-commerce, such as retail merchandise and the consumer-to-consumer
market.

                                principal amount if the underwriters' over-allotment option

Interest Payment Dates........  February 1 and August 1, commencing February 1, 2000.

                                any subsidiary of priceline.com. The indenture does not
                                prohibit or limit the amount of indebtedness, including
                                senior indebtedness, that priceline.com or its subsidiaries
                                may incur. See "Description of Notes--Subordination of
                                Notes."

                                at the option of priceline.com, in whole or in part, at the
                                redemption prices set forth in "Description of Notes,"
                                together with accrued interest.

Fundamental Change............  Upon the occurrence of any Fundamental Change, as defined in
                                the indenture, each holder shall have the right, at such
                                holder's option, to require priceline.com to redeem all or
                                any part of such holder's notes in multiples of $1,000
                                principal amount at a price equal to 100% of the principal
                                amount to be redeemed plus accrued interest. See
                                "Description of Notes--Redemption at Your Option."

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 $88.1 million during the period from July 18,
1997 (inception) through June 30, 1999, before giving effect to $68.6 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 $156.7 million for such period. We have not achieved profitability
and expect to continue to incur losses for at least the next two years. 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, hotel room reservations and related adaptive marketing programs. In order
to increase airline, hotel room 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 and hotel room reservations below
cost. In addition, as our business model evolves, we have introduced and expect
to continue 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 achieve
profitability.

                                       4
<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. Since
these fees historically have involved no direct costs, they have had a
disproportionately positive impact on our gross profit margins. A significant
reduction in consumer acceptance of our adaptive marketing programs, costs that
we may incur in connection with adaptive marketing programs, reductions in fees
paid to us in connection with such programs or any 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.

    During 1998 and the first two quarters of 1999, a substantial majority of
our adaptive marketing revenues were derived from fees paid by credit card
issuers for qualifying credit card applications submitted over the priceline.com
service in connection with customer offers for airline tickets. Through May 1,
1999, almost all of our adaptive marketing revenues were derived from fees
related to a credit card adaptive marketing program with Capital One Bank. In
May 1999, we replaced Capital One Bank with First USA Bank, a leading national
credit card issuer. Since that time, our credit card adaptive marketing program
revenues have been attributable to our adaptive marketing relationship with
First USA.

    Both the Capital One and First USA adaptive marketing programs enable our
customers to increase the amount of their offers by a specified amount by
applying online for a credit card. However, the fee structure of the First USA
program is based on different factors than the factors that were applicable
under the Capital One program. For example, under the Capital One program we
received fees based upon the submission of qualifying applications, while the
First USA program ties a portion of our fees to account activation and usage.
However, since the First USA program only recently commenced, we have no method
of accurately predicting such activation and usage rates. In addition, unlike
the Capital One program, a portion of the fees earned under the First USA
program is required to be reinvested in program incentives. Accordingly, the
First USA program may or may not generate revenues or gross profits comparable
to those previously generated under the Capital One program. The First USA
agreement has a term of five years, subject to certain earlier termination and
repricing rights of First USA. For example, subject to priceline.com's rights of
renegotiation, First USA has the right to terminate the agreement after one year
(and earlier under certain circumstances) if its financial returns under the
adaptive marketing program are not at least equivalent to certain agreed upon
levels. The full financial statement impact of the shift from the Capital One
adaptive marketing program to the First USA adaptive marketing program will not
be known until completion of future periods.

    In addition to our credit card adaptive marketing program with First USA, we
have an adaptive marketing program with E*TRADE for online brokerage services
and expect to commence adaptive marketing programs with Discover Financial
Services, Inc. for credit cards, Sprint Communications Company L.P. for long
distance telecommunications services and Earthlink Network, Inc. for the
provision of Internet services. Our adaptive marketing program with E*TRADE is
based on an oral agreement which may be terminated at any time and most of our
other adaptive marketing programs may be terminated on short notice.

    We cannot guarantee that any of our adaptive marketing programs will
continue beyond their initial terms or, even if continued, that they will be
successful. If they are not successful, our gross profit and results of
operations could be adversely affected.

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

                                       5
<PAGE>
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
notes and our common stock would almost certainly be materially and adversely
affected.

    Our business has no backlog and almost all of our 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
represented approximately 83.7% of total revenue for the six months ended June
30, 1999. Leisure travel, including the sale of leisure airline tickets, is
dependent on personal discretionary spending levels. As a result, sales of
leisure airline tickets and other leisure travel products tend to decline during
general economic downturns and recessions. Unforeseen events, such as political
instability, regional hostilities, increases in fuel prices, travel-related
accidents and unusual weather patterns also may adversely affect the leisure
travel industry. As a result, our business also is likely to be affected by
those events. Significantly reducing our dependence on the airline and travel
industries is likely to take a long time and there can be no guarantee that we
will succeed in reducing that dependence.

    Sales of airline tickets from priceline.com's four largest airline
suppliers, exclusive of Continental Airlines, Inc., which joined the
priceline.com service in July 1999, accounted for approximately 92.0% of airline
ticket revenue for the six months ended June 30, 1999. As a result, currently we
are substantially dependent upon the continued participation of these four
airlines in the priceline.com service in order to maintain and continue to grow
our total airline ticket revenues. We currently have 22 participating airlines.
However, our airline participation agreements:

    - do not require the airlines to make tickets available for any particular
      routes;

    - do not require the airlines to provide any specific quantity of airline
      tickets;

    - do not require the airlines to provide particular prices or levels of
      discount;

    - do not require the airlines to deal exclusively with us in the public sale
      of discounted airline tickets; and

    - generally, can be terminated upon relatively short notice.

                                       6
<PAGE>
These agreements also outline the terms and conditions under which ticket
inventory provided by the airlines may be sold.

    Our agreement with Delta, subject to various exceptions, requires Delta's
approval of the addition of new carriers to the priceline.com service, restricts
the routes for which tickets may be offered by specified carriers through the
priceline.com service and imposes limitations on the code share arrangements of
specified carriers. Delta also may require the exclusion of specific markets in
order for certain other airlines to participate. These provisions could limit
our ability to expand our airline ticket service. In addition, our ability to
transfer or license our intellectual property to other travel providers is
limited in the manner set forth in the agreement.

    It is possible that, as the priceline.com service grows and becomes a
significant channel of distribution for airline tickets and as other carriers
seek participation in the priceline.com service, these competitively restrictive
provisions of the Delta agreement could raise issues under federal and state
antitrust laws. If that happened, either a federal or state government agency or
private party could initiate litigation seeking to enjoin us and Delta from
enforcing these provisions or seeking to collect treble damages. The outcome of
any such litigation would be uncertain. If, however, such a lawsuit resulted in
an injunction or subjected us to damages, our business and financial condition
could suffer.

    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.

    The sale of shares of common stock by the selling stockholders in the
concurrent common stock offering is being made pursuant to the "piggyback"
registration rights contained in the registration rights agreement.
Priceline.com obtained from parties to the registration rights agreement that
hold shares (or presently exercisable warrants to purchase shares) of common
stock available for sale in the concurrent common stock offering a waiver of a
30-day notice period under the agreement and a consent to the assignment of
registration rights by Messrs. Jay Walker and Richard Braddock, each of whom
chose to sell less than his pro rata number of shares in the concurrent common
stock offering. Priceline.com did not obtain such waiver and consent from
certain other parties to the registration rights agreement (comprised of certain
airline participants) because they do not have shares (or presently exercisable
warrants to purchase shares) of common stock available for sale in the
concurrent common stock offering. Priceline.com believes that no damages arise
as a result of the failure to obtain such waiver and consent since such airline
participants do not have shares (or presently exercisable warrants to purchase
shares) of common stock available for sale. Nevertheless, if a disagreement with
such airline participants were to arise, priceline.com can not be certain as to
the effect, if any, that it could have on its relationship with such airline
participants or whether damages or other remedies could be imposed.

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.

                                       7
<PAGE>
    Many of the factors influencing consumers' and sellers' willingness to use
the priceline.com service are outside our control. For example, a labor dispute
that disrupts airline service or an airline accident could make consumers
unwilling to use a service like priceline.com that does not permit the customer
to designate the airline on which the customer purchases a ticket. In addition,
a breach of security on the Internet, even if we were not involved, could make
consumers unwilling to guarantee orders online with a credit card. Consequently,
it is possible that consumers and sellers will never utilize the priceline.com
service to the degree necessary for us to achieve profitability.

WE NEED TO SELL NEW PRODUCTS AND SERVICES

    We are unlikely to make significant profits unless we make new or
complementary products and services and a broader range of existing products and
services available through the priceline.com service. We will incur substantial
expenses and use significant resources in trying to expand the type and range of
the products and services that we offer. However, we may not be able to attract
sellers and other participants 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.

TWO NEW BUSINESSES WE ARE EVALUATING MAY NOT BE SUCCESSFUL

    In addition to broadening the products and services offered through the
priceline.com service, we may expand our current "name your price" business
model into other areas of e-commerce. We currently are evaluating the licensing
of our business model to two new companies. One of these companies is developing
a consumer-to-consumer business in which buyers would make conditional purchase
offers to acquire goods from other consumers. The other would enable consumers
to use the Internet to name the price that they are willing to pay for retail
merchandise, which they would pick up from participating retailers. However, we
have not determined the structure of our relationship with these companies,
which may include, among other things, our licensing of the priceline.com brand
and "name your price" business model and investment in such entities. These new
businesses may not be launched and, if launched, may not be successful. If these
new businesses are not favorably received by consumers, the association of our
brand name and business model with these new entities may adversely affect our
business and reputation and may dilute the value of our brand name. In addition,
to the extent that we may need to invest funds and/or management resources for
the development of these entities, our core business may suffer.

    Expansion of our core business model would expose us to additional risks not
currently applicable to our existing operations. For example, expansion into
retail products would give rise to operational challenges not applicable to our
existing products, such as consumer pick-up arrangements. Moreover, a
consumer-to-consumer service would create risks that we do not face currently,
such as deceptive or fraudulent activities conducted by users on the Web site.
The additional risks associated with an expansion of our core business could
have a material adverse effect on our business generally.

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-

                                       8
<PAGE>
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 $34.9 million during the six months ended
June 30, 1999. 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. These individuals assigned all of their intellectual property
rights relating to the priceline.com service to Walker Digital's affiliate,
Walker Asset Management Limited Partnership. Walker Asset Management,
subsequently transferred the patent rights relating to the priceline.com service
and other related intellectual property rights to us. We, in turn, granted
Walker Digital a perpetual, non-exclusive, royalty-free right and license to use
certain intellectual property related to the priceline.com service for
non-commercial internal research and development purposes.

    Walker Digital also provides us with, among other things, a right to
purchase at fair market value any intellectual property that is in process or
has been fully developed and that is owned and subsequently acquired, developed
or discovered by Walker Digital or Walker Asset Management that will provide
significant value in the use or commercial exploitation of the initially
transferred patent and related intellectual property rights. Conflicts of
interest may arise from time to time between Walker Digital and us with respect
to the potential purchase by us of additional intellectual property rights at
fair market value and the pursuit of overlapping corporate opportunities.

    Walker Digital currently owns assets and intellectual property related to
two new areas of e-commerce into which we may expand our "name your price"
business model, one involving consumer-to-consumer sales and the other involving
the sale of retail merchandise. We may license our brand name and "name your
price" business model to two new companies formed to develop these businesses.
Walker Digital may contribute assets and intellectual property to these
companies in return for an equity interest in these companies.

    Walker Digital owns the intellectual property rights underlying the
technology associated with our adaptive marketing programs. Walker Digital has
licensed to priceline.com the right to use these intellectual property rights
under a perpetual, non-exclusive, royalty-free license agreement. Walker Digital
has pending several United States patent applications directed to different
aspects of the processes and technology supporting our adaptive marketing
programs.

                                       9
<PAGE>
    Walker Digital also provides us with various services, including (1)
research and development assistance; (2) patent planning, maintenance and
prosecution; and (3) other intellectual property services, including 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, for which
Priceline.com collects fees from Walker Digital. We also have guaranteed Walker
Digital's obligations under a lease whereby it leases office space that is used
by both companies.

    Certain of our executive officers and other key employees also are
directors, officers, employees or serve on advisory boards of Walker Digital and
either own, or hold an option to purchase, equity securities of Walker Digital.
Accordingly, because we have interlocking directors and officers and board level
advisors with Walker Digital, there may be inherent conflicts of interest
between Walker Digital and us. If a conflict arises between the management
decisions of priceline.com and Walker Digital, we could lose valuable management
input from our directors and officers who have conflicting obligations.

    Additionally, many of the options granted to employees and consultants of
priceline.com under our 1997 Omnibus Plan entitle holders of such options to
continue to vest options for the then current vesting period during which their
employment or consulting arrangement with priceline.com terminates if such
individuals continue to perform services, throughout the remainder of such
vesting period, for another entity controlled by Mr. Jay S. Walker.
Consequently, we could lose valuable personnel to an entity controlled by Mr.
Walker, while such personnel continue to vest options granted to them by
priceline.com for up to one vesting period.

    We have not adopted any formal plan or arrangement to address these
potential conflicts of interest with Walker Digital or other entities controlled
by Mr. Walker. We intend to review all related-party transactions and any
potential conflicts with Walker Digital and these other entities on a
case-by-case basis.

    Walker Digital owns directly approximately 5.2% of the outstanding common
stock of priceline.com. Additionally, Walker Digital has established an option
plan for its officers and employees that provides for the grant of options to
purchase priceline.com stock owned by Walker Digital.

    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. Mr. Walker also expects to
devote a considerable portion of his time developing and implementing the
consumer-to-consumer and retail merchandise Internet businesses. 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, and in July 1999, Mr. Daniel H. Schulman joined priceline.com
as our President and Chief Operating 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.

                                       10
<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 266 full-time
employees as of August 10, 1999. We also have employed many key personnel since
our launch in April 1998, including our Chairman and Chief Executive Officer and
our President and Chief Operating Officer, and a number of key managerial,
marketing, planning, financial, technical and operations personnel. 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. Publicity about a service
disruption also could cause a material decline in our stock price.

    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.

                                       11
<PAGE>
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
      financing services;

    - 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;

    - traditional travel agencies;

    - consolidators and wholesalers of airline tickets and other travel
      products, including online consolidators such as Cheaptickets.com;

    - 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 AutoNation, 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
      mortgage.com, Quicken Mortgage, E-Loan and iOwn, Inc.; 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 Amazon.com, 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. In addition, as we expand our business through the
introduction of new products and services, we will face competition from
established providers of these products and services. For example, if we expand
into the consumer-to-consumer market either directly or through a licensing
arrangement, we will face competition from established web site operators such
as eBay.

                                       12
<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 issued United
States patent directed to methods and systems for generating airline-specified
time tickets. In addition, we have pending 25 United States and four
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;

    - newly discovered prior art could diminish the value of or invalidate an
      issued 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

                                       13
<PAGE>
distinctions that it does not fall within the scope of our patent. For example,
we are aware of Internet travel services that appear to use customer-offer based
transaction models, but based on the information we have obtained to date, may
not infringe our patent.

    Walker Digital currently owns assets and intellectual property related to
two new areas of e-commerce into which we may expand our "name your price"
business model, one involving consumer-to-consumer sales and the other involving
the sale of retail merchandise. We may license our brand name and "name your
price" business model to two new companies formed to develop these businesses.
Walker Digital may contribute assets and intellectual property to these
companies in return for an equity interest in these companies.

    Walker Digital owns the intellectual property rights underlying the
technology associated with our adaptive marketing programs. Walker Digital has
licensed to priceline.com the right to use these intellectual property rights
under a perpetual, non-exclusive, royalty-free license agreement. Walker Digital
has pending several United States patent applications directed to different
aspects of the processes and technology supporting adaptive marketing programs.

    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 recently received a notice from the United States Patent
and Trademark Office that an undisclosed patent applicant, who we believe is
Woolston, is seeking to provoke an interference on our core buyer-driven
commerce patent. We 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 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 announced in
February 1999 an agreement to license his issued patent and pending patent
applications to the owner of a competing Internet travel service.

    While the interference process is still at an early stage, we believe that
we have meritorious defenses to Woolston's claim, which we intend to pursue
vigorously. Among other things, we believe that the Woolston patent application
does not disclose the inventions covered by the priceline.com patent claims.
However, it is impossible to predict the outcome of an interference with
certainty. While Woolston claims to have an earlier invention date by a period
of approximately sixteen months, the final decision as to priority of invention
would be made by the Patent Office after considering facts provided by each
party during the interference proceeding. If an interference is declared and
thereafter resolved in favor of Woolston, such resolution could result in an
award of some or all of the disputed patent claims to

                                       14
<PAGE>
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 and pay damages from the date such patent
issued at a cost which could significantly adversely affect our business. If
Woolston prevailed in both an interference and an infringement action, then we
could be enjoined from conducting business through the priceline.com service to
the extent covered by the patent claims awarded to Woolston. In addition,
defense of the interference action may be expensive and may divert management
attention away from our business.

    TRADEMARKS, COPYRIGHTS AND TRADE SECRETS

    We regard the protection of our copyrights, service marks, trademarks, trade
dress and trade secrets as critical to our future success. We rely on a
combination of laws and contractual restrictions, such as confidentiality
agreements, to establish and protect our proprietary rights. However, laws and
contractual restrictions may not be sufficient to prevent misappropriation of
our technology or deter others from developing similar technologies. We also
attempt to register our trademarks and service marks in the United States and
internationally. However, effective trademark, service mark, copyright and trade
secret protection may not be obtainable and/or available in every country in
which our services are made available online.

    PENDING LITIGATION

    On January 19, 1999, a complaint was filed 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 us bearing interest at a rate of 6% per year and, in
connection with the loan, received warrants, which have subsequently been fully
exercised, to purchase 62,500 shares of our common stock. On February 22, 1999,
Marketel filed an amended complaint, and on March 17, 1999, Marketel filed a
second amended complaint. The second amended complaint includes as defendants,
Mr. Timothy G. Brier, our Executive Vice President, Travel, Mr. Bruce Schneier,
an individual and consultant to Walker Digital, and Mr. James Jorasch, an
individual and employee of Walker Digital, and 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 second amended complaint, Marketel
alleges, among other things, that the defendants conspired to misappropriate
Marketel's business model, which it describes as a buyer-driven electronic
marketplace for travel services and its appurtenant techniques, market research,
forms, plans and processes, and which an executive of Marketel allegedly
provided to Messrs. Walker and Jaeckle in confidence approximately ten years
ago. The second amended complaint also alleges that three former Marketel
employees are the actual sole inventors or co-inventors of priceline.com's core
buyer driven commerce patent (U.S. patent No. 5794207), which was issued on
August 11, 1998 with Messrs. Jay S. Walker, Bruce Schneier and James Jorasch
listed as the inventors and which patent was assigned to Walker Digital and
thereafter assigned to priceline.com. Marketel asks that the patent's
inventorship be corrected accordingly.

    Based upon publicly available information, we believe that Marketel's fax
and fee-based business was launched in 1991 and ceased operations seven months
later. Our Internet-based model was independently developed at Walker Digital
and priceline.com, and practiced by priceline.com starting in 1998. Based on
publicly available information and Marketel's second amended complaint, we
understand that Marketel operated a fax-based travel information service which
offered consumers, travel agents and/or consolidators the opportunity to
purchase specially printed forms. These forms, when accompanied by an additional
non-refundable fee, allowed prospective ticket buyers to fax to Marketel
credit-card guaranteed bids for airline travel at a bid price specified by the
buyer. We believe that Marketel has not engaged in any

                                       15
<PAGE>
regular commercial activities since ceasing operations in 1992. Based upon
publicly available information, Marketel reactivated its status as a corporation
by satisfying its back-due tax obligations to the State of California shortly
after the filing of the original complaint.

    On February 5, 1999, February 10, 1999 and March 31, 1999, the defendants
filed their answer, amended answer and answer to second amended complaint,
respectively, in which they denied the material allegations of liability in the
complaints. We and all other defendants strongly dispute the material legal and
factual allegations contained in Marketel's second amended complaint and believe
that the second amended complaint is without merit. We intend to defend
vigorously against the action. Since May 28, 1999, there has been a discovery
stay in effect, which was caused by the withdrawal of Marketel's counsel.
Marketel has retained new counsel, and we now anticipate moving forward with
discovery.

    Defending the Marketel litigation may involve significant expense and, due
to the inherent uncertainties of litigation, there can be no certainty as to the
ultimate outcome. Pursuant to the indemnification obligations contained in the
Purchase and Intercompany Services Agreement with Walker Digital, Walker Digital
has agreed to indemnify, defend and hold priceline.com harmless for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.

    DOMAIN NAMES

    We currently hold the Internet domain name "priceline.com," as well as
various other related names. Domain names generally are regulated by Internet
regulatory bodies. The regulation of domain names in the United States and in
foreign countries is subject to change. Regulatory bodies could establish
additional top-level domains, appoint additional domain name registrars or
modify the requirements for holding domain names. As a result, we may not
acquire or maintain the "priceline.com" domain name in all of the countries in
which we conduct business.

    The relationship between regulations governing domain names and laws
protecting trademarks and similar proprietary rights is unclear. Therefore, we
could be unable to prevent third parties from acquiring domain names that
infringe or otherwise decrease the value of our trademarks and other proprietary
rights.

    LICENSES

    In the future, we may license portions of our intellectual property,
including our issued patents, to third parties or to joint ventures or other
entities in which we may have an interest. 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 who historically have purchased through
traditional means of commerce, such as a travel agent for airline tickets or a
branch of a bank for home financings, 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.

                                       16
<PAGE>
    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 generally, as well as 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. Further, the costs related to Year 2000
compliance could be significant. Moreover, participating sellers in
priceline.com services could 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.

                                       17
<PAGE>
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. However, we cannot guarantee that our security measures
will prevent security breaches. 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 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 HIGHLY VOLATILE

    The market price of our common stock is highly volatile and is likely to
continue to 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;

    - operating results that vary from the expectations of securities analysis
      and investors;

    - changes in expectations as to our future financial performance, including
      financial estimates by securities analysts and investors;

    - changes in market valuations of other Internet or online service
      companies;

    - announcements of technological innovations or new services by us or our
      competitors;

    - announcements by us or our competitors of significant contracts,
      acquisitions, strategic partnerships, joint ventures or capital
      commitments;

    - loss of a major seller participant, such as an airline or hotel chain;

    - changes in the status of our intellectual property rights;

    - loss of a major adaptive marketing partner;

    - announcements by third parties of significant claims or proceedings
      against us or adverse developments in pending proceedings;

    - additions or departures of key personnel;

    - future sales of our common stock; and

    - stock market price and volume fluctuations.

    In addition, the trading prices of Internet stocks in general, including
ours, have experienced extreme price and volume fluctuations in recent months.
These fluctuations often have been unrelated or disproportionate to the
operating performance of these companies. The valuations of many Internet
stocks,

                                       18
<PAGE>
including ours, are extremely high based on conventional valuation standards,
such as price to earnings and price to sales ratios. The trading price of our
common stock has increased significantly from the initial public offering price.
These trading prices and valuations may not be sustained. Any negative change in
the public's perception of the prospects of Internet or e-commerce companies
could depress our stock price regardless of our results. Other broad market and
industry factors may decrease the market price of our common stock, regardless
of our operating performance. Market fluctuations, as well as general political
and economic conditions, such as a recession or interest rate or currency rate
fluctuations, also may decrease the market price of our common stock.

    In the past, securities class action litigation often has 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.

SUBSTANTIAL SALES OF COMMON STOCK ELIGIBLE FOR RESALE COULD ADVERSELY AFFECT OUR
  STOCK PRICE AND THE MARKET PRICE OF OUR NOTES

    Sales of a substantial number of shares of common stock after this offering
could adversely affect the market price of our common stock by introducing a
large number of sellers to the market. Given the volatility that exists for our
shares, such sales could cause the market price of our common stock to decline.
Because the notes are convertible into common stock at a fixed conversion price,
a decline in the market price of the common stock could cause a decline in the
market price of the notes.


    Upon completion of this offering and the concurrent common stock offering,
we will have outstanding 146,782,296 shares of common stock. Of these shares,
the 5,500,000 shares of common stock sold in the concurrent common stock
offering, the 10,000,000 shares of common stock sold in our initial public
offering and the 938,540 shares of common stock sold by employees upon exercise
of stock options pursuant to the option exercise program will be freely
tradeable without restriction under the Securities Act of 1933, as amended,
which is commonly referred to as the "Securities Act," unless purchased by
"affiliates" of priceline.com as defined in Rule 144 under the Securities Act.
The shares of common stock issuable upon conversion of the notes being sold in
this offering will be freely tradeable in a similar manner. In addition,
26,582,391 shares are issuable upon exercise of outstanding option granted under
the 1997 Omnibus Plan and the 1999 Omnibus Plan. We have filed a registration
statement on Form S-8 covering the shares of common stock issuable upon exercise
of such options. As a result, when the options are exercised, the shares issued
will be freely tradeable after September 26, 1999 under the Securities Act
unless purchased by "affiliates" of priceline.com, as defined in Rule 144 under
the Securities Act. The balance of our outstanding shares of common stock and
the shares of common stock issuable upon exercise of outstanding warrants will
be "restricted securities" under the Securities Act, subject to restrictions on
the timing, manner and volume of sales of these shares.



    Each of the selling stockholders in the concurrent common stock offering and
Mr. Jay S. Walker, who, after the offerings, will own an aggregate of
147,835,331 shares of common stock, including shares issuable upon exercise of
options and warrants owned by them have agreed, subject to 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, pledge or otherwise dispose of any shares of
common stock. In addition, holders who will own 3,547,311 shares of common stock
after this offering and options to purchase an additional 4,532,504 shares after
this offering agreed in connection with our initial public offering to similar
restrictions until after September 25, 1999. In connection with our option
exercise program, holders of options to purchase 7,676,356 shares of common
stock registered on our Form S-8 entered into lock-up agreements restricting the
exercise of their options and sale of the underlying shares until 180 days after
the date of this prospectus without our prior written consent.


                                       19

    After giving effect to these contractual restrictions, holding periods under
Rule 144 and shares that may be issued upon exercise of outstanding options and
warrants, we estimate that additional shares of common stock will be available
for sale in the public market as follows:

Since many of these shares were purchased at prices substantially below current
market prices, we believe a significant number of these shares will be sold when
eligible for resale.


    Upon consummation of this offering and the concurrent common stock offering
and subject to the foregoing lock-up agreements, holders of up to 142,104,432
shares of common stock and securities exercisable for shares of common stock
will have various rights to request the registration of their shares under the
Securities Act. Of such shares, approximately 10,010,000 shares are not subject
to the 180-day lock-up relating to the concurrent public offering. "Demand"
registration rights with respect to an aggregate of approximately 5,190,000
shares could be exercised following expiration of the initial public offering
lock-up on September 25, 1999, excluding warrants to purchase up to 1,125,000
shares which, by their terms, are not exercisable during the 180-day lock-up
period relating to the concurrent public offering. In the event such a demand is
made, 3,690,000 additional shares could be registered pursuant to "piggy-back"
registration rights. If such rights are exercised in respect of shares that, at
that time, are not available for sale publicly pursuant to Rule 144, then such
shares could be sold in the public market on dates earlier than the dates as of
which such shares are reflected as available for sale in the table above. We
believe holders of registration rights are likely to exercise those rights as to
some or all of their shares when they are eligible to do so. Upon the
effectiveness of such a registration, all shares covered by such registration
statement would be freely transferable.



    If the concurrent common stock offering does not occur, selling stockholders
holding an aggregate of 40,553,090 shares of common stock or options and
warrants to acquire those shares will not be subject to the 180 day lock-up
described above and these shares would also be available for resale after
September 25, 1999, upon expiration of the lock up period from priceline.com's
initial public offering.


    Walker Digital also owns directly approximately 5.2% of our outstanding
common stock. Walker Digital has established an option plan for its officers and
employees that provides for the grant of options to purchase common stock held
by Walker Digital.

    Future sales of our common stock, or the availability of our common stock
for sale, could adversely affect the market price for our common stock or our
ability to raise capital by offering equity securities.

THE NOTES WILL BE SUBORDINATED TO ALL SENIOR DEBT

    The notes will be unsecured and subordinated in right of payment to all
existing and future senior indebtedness of priceline.com. In the event of
bankruptcy, liquidation or reorganization of priceline.com or upon acceleration
of the notes due to an event of default under the indenture and in certain other
events, our assets will be available to pay obligations on the notes only after
all senior indebtedness has been paid, and there may not be sufficient assets
remaining to pay amounts due on any or all of the notes then outstanding. The
notes also will be effectively subordinated to the liabilities, including trade
payables, lease obligations and preferred stock, if any, of any subsidiary of
priceline.com. The indenture does not prohibit or limit the incurrence of senior
indebtedness or the incurrence of other indebtedness and other liabilities by
priceline.com or any subsidiary of priceline.com. The incurrence of additional
indebtedness

                                       20
<PAGE>

and other liabilities by priceline.com or any subsidiary of priceline.com could
adversely affect priceline.com's ability to pay its obligations on the notes. As
of June 30, 1999, priceline.com had no senior indebtedness outstanding and had
no subsidiaries. We anticipate that from time to time priceline.com will incur
senior indebtedness and establish or acquire subsidiaries. Any subsidiaries will
from time to time incur other additional indebtedness and liabilities. See
"Description of Notes--Subordination of Notes."


WE MAY BE UNABLE TO REDEEM THE NOTES UPON A FUNDAMENTAL CHANGE

    We may be unable to redeem the notes when redemption is required. Upon a
fundamental change, as defined in the indenture, you may, at your option,
require us to redeem all or a portion of your notes. If a fundamental change
were to occur, we cannot assure you that we would have sufficient funds to pay
the redemption price for all notes tendered by the holders of the notes. Any
future credit agreements or other agreements relating to other indebtedness
(including senior indebtedness) to which we become a party may contain
provisions which would render us in default under such credit facility if a
fundamental change were to occur, may also expressly prohibit the repurchase of
the notes upon a fundamental change or may provide that a fundamental change
constitutes an event of default under that agreement. If a fundamental change
occurs at a time when we are prohibited from purchasing or redeeming notes, we
could seek the consent of our lenders to the redemption of notes or could
attempt to refinance the borrowings that contain such prohibition. If we do not
obtain a consent to repay those borrowings, we could not purchase or redeem the
notes. Our failure to redeem tendered notes would constitute an event of default
under the indenture, which might constitute a default under the terms of our
other indebtedness. In such circumstances, or if a fundamental change would
constitute an event of default under our senior indebtedness, the subordination
provisions of the indenture would restrict payments to the holders of notes. The
term "fundamental change" is limited to certain specified transactions and may
not include other events that might adversely affect our financial condition.
Our obligation to offer to redeem the notes upon a fundamental change would not
necessarily afford holders of the notes protection in the event of a highly
leveraged transaction, reorganization, merger or similar transaction involving
priceline.com. See "Description of Notes--Redemption at Your Option."

ABSENCE OF PUBLIC MARKET FOR THE NOTES

    A public market may not develop for the notes. Prior to this offering there
has been no trading market for the notes. Although the underwriters have advised
us that they currently intend to make a market in the notes, they are not
obligated to do so and may discontinue such market making at any time without
notice. In addition, such market making activity will be subject to the limits
imposed by the federal securities laws. Accordingly, we cannot assure you that
any market for the notes will develop or, if one does develop, that it will be
maintained. If an active market for the notes fails to develop or be sustained,
the trading price of the notes could be materially adversely affected.

WE CANNOT SERVICE THE NOTES FROM OPERATING CASH FLOW

    We do not generate positive cash flow from operations. Our earnings were
insufficient to cover our fixed charges by $112.2 million for the year ended
December 31, 1998 and the shortfall was $31.4 million for the six months ended
June 30, 1999. We cannot currently meet our debt service requirements or repay
the notes at maturity out of cash generated from our operations. As a result,
our ability to service the notes and our other debt will depend on our ability
to obtain funds from sources other than our operations. Unless the notes are
converted or we are able to generate additional cash from our operations, our
ability to repay the notes at maturity will depend on our ability to refinance
the notes.

    The indebtedness represented by the notes could:

    - make it more difficult for us to obtain financing in the future,

    - limit our flexibility in planning for or reacting to changes in our
      business, and

                                       21
<PAGE>
    - make ourselves more vulnerable if our business experiences a downturn.

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 products
and 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.com is
registered as a "seller of travel" under the California Seller of Travel Act and
is a member of the Airlines Reporting Corporation. In addition, a number of
state travel laws and regulations require compliance with specific disclosure,
bond and/or other requirements.

    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. With
the planned expansion of our new automobile service from the New York
metropolitan area to all 48 contiguous states, priceline.com will attempt to
register as an automobile broker/dealer in the jurisdictions where registration
is required, provided that it can reasonably comply with the requirements for
registration imposed by each jurisdiction. However, we may not be able to
register in all states. For example, we will not be able to register in a
jurisdiction that requires a dealer zoned lot or a franchise agreement with
manufacturers of the automobiles to be sold. We will work with the regulators of
the various jurisdictions where enforcement officials advise us that
registration is required to obtain waivers of such requirements, but we may not
be successful in our efforts.



    In jurisdictions where we cannot obtain registration, it is possible that
state regulatory bodies could take a strict enforcement position and we may be
unable to continue to make our new automobile services available in those
jurisdictions.


    HOME FINANCING SERVICES

    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 financing service in January 1999. LendingTree serves
as the back-end processing system, which presents offers we receive to multiple
mortgage lending institutions for consideration, for all of priceline.com's home
financing services. We provide and are responsible for maintaining

                                       22
<PAGE>
the home financing service on our Web site and develop and purchase all
advertising. LendingTree compensates us for the fair market value of our
non-referral services. We believe that offering the home financing 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 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 back-end processing system, which presents offers
we receive to multiple mortgage lending institutions for consideration, for the
home financing service on our Web site and is responsible for maintaining the
necessary and appropriate state registrations and licenses associated with
LendingTree's 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
financing service could be materially and adversely affected and we may be
unable to continue to make our home financing service available.

    We are exploring the possibility of acquiring a minority interest in, and
licensing the priceline.com name and business model to, a newly formed
subsidiary of a federally chartered savings and loan association. This entity
may be known as "priceline.mortgage.com" and also may serve as an entity that
could accept mortgage applications or mortgage qualification loans.

    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 also
are 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 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

                                       23
<PAGE>
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

    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. We recently met
with representatives of the Internal Revenue Service to informally discuss our
submission. We intend to revise and resubmit our request to address certain
factual and legal inquiries raised during our meeting. The actual ruling by the
Internal Revenue Service 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 $766,339 in additional taxes as of June 30, 1999. We
have accrued for such potential liability in our condensed balance sheet as of
June 30, 1999 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.

    STATE TAXES

    We file tax returns in such states as required by law based on principles
applicable to traditional businesses. In addition, we do not collect sales or
other similar taxes in respect of transactions conducted through the
priceline.com service (other than the federal air transportation tax referred to
above). However, one or more states could seek to impose additional income tax
obligations or sales tax collection obligations on out-of-state companies, such
as ours, which engage in or facilitate online commerce. A number of proposals
have been made at state and local levels that could impose such taxes on the
sale of products and services through the Internet or the income derived from
such sales. Such proposals, if adopted, could substantially impair the growth of
e-commerce and adversely affect our opportunity to become profitable.

    Legislation limiting the ability of the states to impose taxes on
Internet-based transactions recently has been enacted by the United States
Congress. However, this legislation, known as the Internet Tax Freedom Act,
imposes only a three-year moratorium, which commenced October 1, 1998 and ends
on October 21, 2001, on state and local taxes on (1) electronic commerce where
such taxes are discriminatory and (2) Internet access unless such taxes were
generally imposed and actually enforced prior to October 1, 1998. It is possible
that the tax moratorium could fail to be renewed prior to October 21, 2001.
Failure to renew this legislation would allow various states to impose taxes on
Internet-based commerce. The imposition of such taxes could adversely affect our
ability to become profitable.

                                       24
<PAGE>
    PAYROLL TAXES RELATED TO OPTION EXERCISES


    We currently have outstanding non-qualified stock options to purchase
26,582,391 shares issued to various employees, consultants and directors
pursuant to the 1997 Omnibus Plan and the 1999 Omnibus Plan. The options entitle
the holders to purchase common stock at a weighted average exercise price of
approximately $11.46 per share, subject to adjustment in accordance with the
1997 Omnibus Plan and the 1999 Omnibus Plan. Upon exercise of an option, we will
be required to make payments on behalf of the option holders for certain payroll
related taxes such as Social Security and Medicare. These payroll taxes will
appear as a general and administrative expense on our statement of operations
and will amount to approximately 1.5% to 2.0% of the difference between the
exercise price and the then fair market value of the common stock at the time of
exercise. However, upon exercise of outstanding options, we will be paid the
exercise price of the options that are exercised. We also will be entitled to an
income tax deduction equal to the sum of (1) the difference between the exercise
price of the option and the then fair market value of the common stock at the
time of exercise and (2) the total amount of payroll related tax payments. As
the calculation of this expense is directly dependent upon our stock price and
the exercise of options is in the sole discretion of the holder of the options,
the amount and timing of the expense and the timing of the corresponding income
tax deduction are not currently able to be determined and are not within our
control.


CONCENTRATED CONTROL COULD ADVERSELY AFFECT STOCKHOLDERS


    Upon consummation of this offering and the concurrent common stock offering,
Mr. Jay S. Walker, the Founder and Vice Chairman of priceline.com, and Mr.
Richard S. Braddock, Chief Executive Officer of priceline.com, together with
their respective affiliates (including, with respect to Mr. Walker, Walker
Digital) beneficially own approximately 42.4 and 12.0 percent, 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
our recent initial public offering, this offering and our concurrent common
stock 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 subordinated 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.

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

                                       25
<PAGE>
favorable. Our board of directors has the authority to issue up to 150,000,000
shares of preferred stock par value $0.01 per share, of priceline.com and to
determine the price and the terms, including preferences and voting rights, of
those shares without stockholder approval. Although we have no current plans to
issue additional shares of our preferred stock, any such issuance could:

    - have the effect of delaying, deferring or preventing a change in control
      of our company;

    - discourage bids for our common stock at a premium over the market price;
      or

    - adversely affect the market price of, and the voting and other rights of
      the holders of, our common stock.

    We are subject to certain Delaware laws that could have the effect of
delaying, deterring or preventing a change in control of our company. One of
these laws prohibits us from engaging in a business combination with any
interested stockholder for a period of three years from the date the person
became an interested stockholder, unless certain conditions are met. In
addition, certain provisions of our certificate of incorporation and by-laws,
and the significant amount of common stock held by our executive 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 $241.9
million, and the net proceeds of our sale of 2,000,000 shares of common stock in
the concurrent common stock offering are estimated to be approximately $133.3
million, in each case after deducting the underwriting discounts and estimated
offering expenses. Our management will retain broad discretion as to the
allocation of the proceeds of this offering and the concurrent common stock
offering.

                                USE OF PROCEEDS


    The net proceeds to priceline.com from the sale of its   % convertible
subordinated notes in this offering are estimated to be approximately $133.3
million, after deducting estimated offering expenses of $0.6 million and the
underwriting discounts and commissions. If the underwriters' over-allotment
option is exercised in full, the net proceeds to priceline.com would be
approximately $278.3 million, after deducting estimated offering expenses of
$0.6 million and the underwriters' discounts and commissions. Priceline.com will
not receive any proceeds from the sale of shares of common stock by the selling
stockholders in the concurrent common stock offering. The net proceeds to
priceline.com from the sale of the 2,000,000 shares of common stock offered by
it in the concurrent common stock offering are estimated to be approximately
$153.5 million, after deducting estimated offering expenses of $1.5 million and
the underwriting discounts and commissions. Priceline.com intends to use the net
proceeds, over time, for general corporate purposes, including working capital,
funding of anticipated operating losses, expenses associated with our
advertising campaigns, brand-name promotions and other marketing efforts,
funding of product and service expansion and capital expenditures. Priceline.com
also could use a portion of the net proceeds, currently intended for general
corporate purposes, to invest in joint ventures or other collaborative
arrangements, or to invest in businesses, technologies, products or services. In
particular, a portion of the proceeds may be used to make investments in and/or
loans to two new business entities with which priceline.com is exploring the
possibility of licensing its brand name and "name your price" business model.


    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."

                          PRICE RANGE OF COMMON STOCK

    Priceline.com common stock has been quoted on the Nasdaq National Market

    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 for the
foreseeable future. Priceline.com currently intends to retain future earnings,
if any, to finance the expansion of its business.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL EVENTS OR RESULTS MAY DIFFER MATERIALLY FROM THOSE
INDICATED IN SUCH FORWARD-LOOKING STATEMENTS. SEE "SPECIAL NOTE REGARDING
FORWARD-LOOKING STATEMENTS." THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION
AND RESULTS OF OPERATIONS OF PRICELINE.COM ALSO SHOULD BE READ IN CONJUNCTION
WITH THE FINANCIAL STATEMENTS AND RELATED NOTES THERETO INCLUDED ELSEWHERE IN
THIS PROSPECTUS.

OVERVIEW

    Priceline.com has pioneered a unique e-commerce pricing system known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price"--priceline.com collects consumer demand, in the
form of individual customer offers guaranteed by a credit card, for a particular
product or service at a price set by the customer. Priceline.com then either
communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether it can fulfill the
customer's offer on the basis of the pricing information and rules established
by the sellers. Consumers agree to hold their offers open for a specified period
of time and, once fulfilled, offers cannot be canceled. Priceline.com benefits
consumers by enabling them to save money, while at the same time benefitting
sellers by providing them with an effective revenue management tool capable of
identifying and capturing incremental revenues. By requiring consumers to be
flexible with respect to brands, sellers and product features, priceline.com
enables sellers to generate incremental revenue without disrupting their
existing distribution channels or retail pricing structures.

    Priceline.com was formed in July 1997 and its primary activities during the
period prior to launch consisted of recruiting and training employees,
developing its business model, implementing systems to support its business
model, developing relationships with seller participants and developing the
priceline.com brand. Priceline.com commenced operations in April 1998 with the
sale of leisure airline tickets. Since that time, priceline.com's business has
grown significantly and the priceline.com service now includes the following
products and services:

    - leisure airline tickets, provided by six domestic and 16 international
      airline participants;

    - new automobiles, which was launched on a test basis in the New York
      metropolitan area in July 1998;

    - hotel room reservations, which was launched in October 1998, offers hotel
      rooms in substantially all major United States markets and includes as
      participants more than 10 leading national hotel chains; and

    - home financing services, which was launched in January 1999 with home
      mortgage services and now also includes home equity loans and refinancing
      services.

Through the innovative use of "adaptive marketing programs," priceline.com also
markets customer acquisition programs for third parties. These programs
facilitate the completion of a higher percentage of successful transactions
through the priceline.com service while generating fee income for the company.
Priceline.com also is exploring expansion of its core "name your price" business
model to other areas of e-commerce, such as retail merchandise and the
consumer-to-consumer market.


    The number of full-time employees of priceline.com increased from 10 to 263
during the period from inception to June 30, 1999, and as of August 10, 1999,
priceline.com had 266 full-time employees.


    Priceline.com generates revenues in a variety of ways depending on the
product or service sold. With respect to its airline ticket and hotel room
reservation services, priceline.com recognizes as revenue the

                                       30
<PAGE>
customer's named price, net of taxes, and records as the cost of revenue the
fare or rate charged by the seller. With respect to its automobile service, it
earns a fixed fee from both the customer and the seller after the transaction is
consummated. With respect to its home financing service, it receives marketing
fees equal to a percentage of the net revenue generated by the service, 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.
Additionally, priceline.com generates revenues from third party sources,
including airline ticket processing fees from consumers and ancillary
reservation booking fees from the Worldspan reservation system for
priceline.com's booking of airline flight segments and hotel reservations
through the Worldspan system. Consumer fees are payable and recognized only upon
completion of successful transactions.

    All offers made through the priceline.com service are guaranteed by a
customer credit card and credit cards are the only form of payment accepted by
priceline.com. The manner in which and time at which revenues are recognized
differs depending on the product or service sold through the priceline.com
service. With respect to airline ticket and hotel room reservation services,
revenues are generated by transactions with customers who make offers to
purchase airline tickets and reserve hotel rooms supplied by participating
sellers. Revenues and related costs are recognized if, and when, priceline.com
accepts the customer's offer and charges the customer's credit card. Because
priceline.com is the merchant of record in these transactions, revenue for these
services includes the offer price paid by the customer, net of certain taxes and
fees. Airline and hotel revenues also may include fees from third parties for
adaptive marketing programs. With respect to automobile services, fees or other
payments payable by the seller and/or the customer are recognized as revenue.
With respect to home financing services, priceline.com receives no fees from
consumers. Priceline.com recognizes revenue from marketing fees paid directly by
LendingTree through the operation of its home financing services. Because
priceline.com acts as an intermediary between the customer and the seller in
auto and home financing transactions, revenues for these products and services
is recorded at the amount of the fee received, and not on the value of the
underlying transaction, when the transaction is completed. Automobile and home
financing services revenues also may include fees from third parties for
adaptive marketing programs.

    When making offers through the priceline.com service, consumers are
permitted to make only one offer within a seven day period unless they change
some feature of their itinerary, such as the date on which or the airport from
which they are willing to fly. In April 1999, priceline.com introduced a new
"checkstatus" feature on its Web site that invites consumers whose initial
requests are not satisfied to change a feature of their itinerary and resubmit
revised offers without having to start the offer submission process over again.
Commencing with the second quarter of 1999, priceline.com treats each initial
offer and any resubmitted offer made in response to the checkstatus invitation
as a single offer for purposes of measuring its offer fulfillment rates.

    During the period from launch through June 30, 1999, priceline.com collected
guaranteed offers for approximately 5.1 million airline tickets, representing
approximately $1.1 billion in total consumer demand. This demand resulted in
sales of approximately 762,000 airline tickets, representing approximately
$165.2 million in revenue.

    Because the priceline.com system does not set minimum offer thresholds, and
consumers are not charged to make offers for airline tickets and other products,
it is expected that priceline.com will receive a significant number of
unreasonable or fantasy offers. Accordingly, priceline.com also analyzes the
percentage of "reasonable" ticket requests that it is able to fill.
Priceline.com considers an offer for an airline ticket to be "reasonable" when
it is no more than 30% lower than the lowest generally available advance-
purchase fare for the same route. Using this standard, the overall percentage of
ticket requests considered reasonable for the six-month period ended June 30,
1999 was approximately 55.3%. The 626,860 tickets sold through priceline.com
during the six-month period represented approximately 34.7% of the combined
reasonable ticket requests for domestic and international flights. For domestic
routes where priceline.com's airline participants have strong coverage, that
percentage was higher, with approximately 40.0%

                                       31
<PAGE>
of all reasonable requests fulfilled for the same six-month period. The
percentage of reasonable offers that priceline.com is able to fill can also vary
depending on the particular route. The following table sets forth, for the
periods presented, data regarding the total percentage of "reasonable" ticket
requests fulfilled by priceline.com:

(1) For this period, due to the introduction of the new "checkstatus" feature,
    initial offers and any resubmitted offers made in response to this feature
    were treated as a single offer; comparisons with other periods may not be
    meaningful as resubmitted offers were considered separate offers in prior
    periods.

    Since its inception, priceline.com has incurred net losses in each fiscal
quarter. Priceline.com incurred net losses of $88.1 million during the period
from July 18, 1997 (inception) through June 30, 1999, before giving effect to
$68.6 million of non-cash charges arising from equity issuances to a number of
our participating airlines, its chief executive officer and other parties, as
more fully described below. As of June 30, 1999, priceline.com had an
accumulated deficit of $156.7 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 at least the next two years.
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."


    Priceline.com currently has outstanding non-qualified stock options to
purchase 26,582,391 shares issued to various employees, consultants and
directors pursuant to the 1997 Omnibus Plan and the 1999 Omnibus Plan. The
options entitle the holders to purchase common stock at a weighted average
exercise price of approximately $11.46 per share, subject to adjustment in
accordance with the 1997 Omnibus Plan and the 1999 Omnibus Plan. Upon exercise
of an option, priceline.com will be required to make payments on behalf of the
option holders for certain payroll related taxes such as Social Security and
Medicare. These payroll taxes will appear as a general and administrative
expense on priceline.com's statement of operations and will amount to
approximately 1.5% to 2.0% of the difference between the exercise price and the
then fair market value of the common stock at the time of exercise. However,
upon exercise of outstanding options, priceline.com will be paid the exercise
price of the options that are exercised. Priceline.com also will be entitled to
an income tax deduction equal to the sum of (1) the difference between the
exercise price of the option and the then fair market value of the common stock
at the time of exercise and (2) the total amount of payroll related tax
payments. As the calculation of this expense is directly dependent upon
priceline.com's stock price and the exercise of options is in the sole
discretion of the holder of the options, the amount and timing of the expense
and the timing of the corresponding income tax deduction are not currently able
to be determined and are not within priceline.com's control. Priceline.com
estimates that, in connection with the exercise of outstanding options pursuant
to the option exercise program, in the third quarter of 1999 it will (x) record
expenses of approximately $1.3 million in respect of such payroll related taxes;
(y) increase additional paid-in capital by approximately $944,000 in


                                       32
<PAGE>
respect of the exercise price of such options; and (z) increase common stock by
approximately $7,700 in respect of the par value of the shares purchased upon
exercise of such options.

    For the year ended December 31, 1998, priceline.com recorded aggregate
non-cash charges of $67.9 million. Of this amount, $6.5 million related to the
issuance of 8,125,000 shares of common stock to Mr. Richard S. Braddock, the
Chairman and Chief Executive Officer of priceline.com, and $61.1 million related
to the issuance of warrants to purchase 19,744,402 shares of common stock,
including warrants to purchase 19,556,902 shares of common stock issued to a
number of our participating airlines.

    In August 1998, priceline.com entered into a warrant agreement with Delta to
purchase up to 18,892,603 shares of common stock at an exercise price of
approximately $0.93 per share. Vesting was contingent upon achievement of
certain predetermined performance thresholds. However, there was no penalty for
failure to provide ticket inventory to satisfy these performance thresholds.
Accordingly, no expense was recorded when the warrant was issued. On December
31, 1998, priceline.com amended its agreement with Delta to eliminate the
vesting contingencies and fix the number of shares subject to the warrant at
18,619,402. The amended warrant issued to Delta will become exercisable at the
earlier of seven years or upon the achievement of certain performance
thresholds. However, the agreement does not require Delta to make any
performance commitments, is non-exclusive and allows Delta to participate in
other programs similar to the priceline.com service. Included in the non-cash
charges described above is approximately $58.7 million reflecting the fair value
of the Delta warrant on December 31, 1998.


    During July 1999, priceline.com issued to Continental Airlines a warrant to
purchase common stock that will become exercisable upon the earlier of July 2004
or upon the achievement of certain performance thresholds. However, the
agreement does not require Continental to make any performance commitments.
Accordingly, priceline.com will incur a non-cash charge of approximately $88.4
million during the quarter ending September 30, 1999 representing the fair value
of the warrant on the grant date.


    Priceline.com's travel agency license was previously held by Priceline
Travel, a separate company that was owned by Mr. Jay S. Walker, priceline.com's
Founder and Vice Chairman, and all of its airline ticket sales were effected
through Priceline Travel, which was merged with and into priceline.com as of
March 24, 1999. Accordingly, the financial statements of Priceline Travel as of
December 31, 1997 and December 31, 1998 (restated) and for the period July 18,
1997 (Inception) to December 31, 1997 and for the year ended December 31, 1998
(restated) are presented on a combined basis with priceline.com.

RESULTS OF OPERATIONS

    Priceline.com was formed in July 1997, but did not commence operations until
April 1998. Accordingly, comparisons with prior periods are not meaningful.

SIX MONTHS ENDED JUNE 30, 1999

    REVENUES

    Total revenues for the six months ended June 30, 1999 were $161.0 million.
Revenues for the period were comprised primarily of (1) transaction revenues
representing the selling price of airline tickets and hotel room reservations;
(2) fee income from adaptive marketing programs offered in connection with
priceline.com's product offerings; (3) ancillary revenues consisting of
Worldspan reservation booking fees and airline ticket processing fees; and (4)
fee income from priceline.com's home financing and auto programs.

    On April 23, 1999, the adaptive marketing program with Capital One ended and
priceline.com commenced its credit card adaptive marketing program with First
USA. The fee structure of the First USA program is based on different factors
and may or may not result in revenues comparable to those under the Capital One
program. For example, under the Capital One program priceline.com's fees were
based upon the submission of qualifying credit card applications, while the
First USA program ties a portion of

                                       33
<PAGE>
priceline.com's fees to account activation and usage. Because, to date, there is
no meaningful activation and usage experience upon which to draw, priceline.com
cannot predict the degree to which revenues ultimately will be recognized under
the First USA program. In addition, priceline.com expects that future
contributions to adaptive marketing revenues from credit card adaptive marketing
programs may decline on a percentage basis, as agreements with new adaptive
marketing suppliers are reached and become operative. At the same time,
increased transaction activity, particularly associated with airline ticket
sales and related processing fees, is likely to provide an increasing portion of
revenues. All of these factors are likely to diminish the proportion of
priceline.com's revenues provided by its credit card adaptive marketing
programs.

    During the six months ended June 30, 1999, priceline.com also earned revenue
from its Customer Affinity Share Purchase Program, the first phase of its
adaptive marketing program with E*TRADE. Revenues from this program related
specifically to the referral of priceline.com customers to E*TRADE in connection
with priceline.com's initial public offering and, therefore, are not recurring.
Priceline.com also commenced the second phase of its adaptive marketing program
with E*TRADE under which E*TRADE compensates priceline.com for offering
priceline.com customers the opportunity to open an account with E*TRADE while
visiting or making an offer on the priceline.com Web site. Priceline.com intends
to continue to add adaptive marketing programs so that consumers have a variety
of programs from which to choose and priceline.com has a diversified source of
adaptive marketing revenues.

    Priceline.com's ancillary revenues for the six month period increased as a
result of volume driven increases in Worldspan reservation booking fees and a
recently introduced processing fee. Revenues from these sources are linked to
airline ticket sales and, accordingly, will increase or decrease in future
periods in relation to changes in the volume of airline ticket sales. Worldspan
reservation booking fees also are linked to hotel reservations booked through
the Worldspan system.

    COST OF REVENUES AND GROSS PROFIT

    Cost of revenues for the six months ended June 30, 1999 totaled $145.1
million, consisting of product costs of $144.3 million and supplier warrant
costs of $761,518. Product costs were comprised of 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. Product costs also included the cost of hotel rooms from
priceline.com's suppliers, net of hotel tax. Supplier warrant costs represent a
non-cash expense related to the issuance of common stock warrants to one of
priceline.com's airline program participants in January 1999. Priceline.com
anticipates that it will recognize additional supplier warrant costs in the
amount of approximately $381,000 in each of the next six fiscal quarters.

    Gross profit, which is comprised of revenues less cost of revenues, was
$15.9 million for the six months ended June 30, 1999. Gross margin was 9.9% for
the period. Excluding the effect of non-cash supplier warrant costs,
priceline.com would have had gross profit of $16.7 million and gross margin of
10.3% for the six months ended June 30, 1999. Gross profit and gross margin are
affected by the price at which priceline.com causes offers to be fulfilled and
by the level of fees generated by adaptive marketing programs. Priceline.com is
able to manage the level of gross margins by controlling the price at which it
will cause offers to be fulfilled. During the first quarter of 1999,
priceline.com chose 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. As a result of the
growth of the priceline.com service, priceline.com reduced the percentage of
airline tickets that it chose to sell below cost during the second quarter,
thereby improving gross margins on airline ticket sales. Because the fees
generated by adaptive marketing revenue and ancillary revenues did not involve
separate costs, adaptive marketing revenues and ancillary revenues had a
disproportionately positive impact on total gross margins and made a very
substantial contribution to priceline.com's gross profit for the six months
ended June 30, 1999. If our transaction activity continues to grow,
priceline.com expects the proportion of its gross profit and gross margin
attributable to adaptive marketing revenues to decline.

                                       34
<PAGE>
    Gross margins for the six months ended June 30, 1999 also were affected by a
somewhat lower gross margin in the second quarter of 1999 compared to the first
quarter of 1999. See "Quarterly Results of Operations" below. Gross margins for
the second quarter of 1999 were affected by a change in revenue mix, resulting
from a greater percentage of revenues being attributable to transaction revenues
rather than fee based revenues. Fee-based revenues, such as adaptive marketing
revenues, ancillary revenues and revenues from financial services and
automobiles, have higher margins than transaction revenues, which are derived
from the spread between customer offers and the product costs.

    OPERATING EXPENSES

    SALES AND MARKETING.  Sales and marketing expenses for the six months ended
June 30, 1999 totaled $34.9 million, or 21.7% of revenues. Approximately 65.0%
of sales and marketing expenses were comprised of advertising and promotion
expenses. The remaining expenses consisted primarily of (1) fees payable to a
third party service provider that operates priceline.com's call center; (2)
credit card processing fees; (3) provisions for customer credit card
charge-backs (based upon a percentage reflecting priceline.com's historical
experience); and (4) compensation for priceline.com's sales and marketing
personnel.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses for the six
months ended June 30, 1999 totaled $9.2 million, or 5.7% of revenues. General
and administrative expenses for the period were comprised primarily of
compensation for personnel, fees for outside professionals, telecommunications
and other overhead costs, including occupancy expense.

    SYSTEMS AND BUSINESS DEVELOPMENT.  Systems and business development expenses
for the six months ended June 30, 1999 totaled $5.7 million, or 3.5% of
revenues. Systems and business development expenses for the period were
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.

    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 requires capitalization of
certain costs of computer software developed or obtained for internal use.
Priceline.com adopted this SOP on January 1, 1999 and, during the six-month
period ended June 30, 1999, priceline.com capitalized approximately $5.7 million
of computer software developed or obtained for internal use. Amortization of
such costs aggregated approximately $149,000 during the six month period ended
June 30, 1999.

    INTEREST INCOME, NET

    Interest income, net for the six months ended June 30, 1999 totaled $2.4
million, reflecting approximately $2.5 million of interest income earned by
priceline.com on its cash balances, net of interest expense for the period. Cash
balances increased during this period due to priceline.com's initial public
offering in April 1999.

SIX MONTHS ENDED JUNE 30, 1998

    Priceline.com commenced its service on April 6, 1998 with the sale of
leisure airline tickets. Revenues from the sale of airline tickets during the
six month period ended June 30, 1998 were $7.0 million. Cost of revenues during
this period exceeded such revenues by approximately $900,000. Priceline.com
chose to sell a substantial number of leisure airline tickets below its cost
during this period in order to increase airline revenues, build a record of
successful transactions and enhance the priceline.com brand.

                                       35
<PAGE>

    In addition, priceline.com incurred operating expenses of $17.9 million,
consisting of sales and marketing expenses of $7.8 million, general and
administrative expenses of $4.8 million and systems and business development
expenses of $5.4 million. These activities resulted in an operating loss of
$18.9 million and, after consideration of interest income, a net loss of $18.7
million for the six month period ended June 30, 1998.


YEAR ENDED DECEMBER 31, 1998

    RESTATEMENT

    Subsequent to the issuance of priceline.com's combined 1998 financial
statements, priceline.com's management determined that the calculation of the
fair value of the Delta warrant, other airline warrants and the beneficial
conversion feature on the Series B preferred stock should be revised. The fair
value of the Delta warrant and the other airline warrants has been revised to
reflect the change in the volatility assumption from 50% to 132%, eliminate the
"large block" and lack of marketability discounts, and consider the warrant's
anti-dilution and exercisability features. As a result, the 1998 combined
financial statements have been restated from the amounts previously reported to
recognize an additional $22.0 million of expense based upon the revised fair
value of the warrants at December 31, 1998, of which $3.0 million is included in
the cost of revenues-supplier warrant costs and $19.0 million is included in
expenses-supplier start-up warrant costs. In addition, the value of the
beneficial conversion feature on the Series B preferred stock has been revised
to calculate such amount based on 22,500,000 shares. As a result, additional
paid-in capital and accumulated deficit have been restated from amounts
previously reported to recognize an additional $883,424 of accretion of
preferred stock based on the revalued beneficial conversion feature.

    A summary of the significant effects of the restatement is as follows:

    previously reported has been restated for a 1.25 for one stock split.

    REVENUES

    Total revenues for the year ended December 31, 1998 were $35.2 million.
Since commencement of operations in April 1998, essentially all revenues
consisted of airline ticket sales, hotel room reservations and related adaptive
marketing programs. Approximately $4.0 million of total revenues were
attributable to adaptive marketing programs, all of which were attributable to
priceline.com's third-party credit card marketing program with Capital One Bank.
See "--Cost of Revenues and Gross Profit (Loss)." Priceline.com's automobile
sales service, which was launched on a test basis in the New York metropolitan
area in July 1998, did not contribute materially to revenues during the period.

                                       36
<PAGE>
    COST OF REVENUES AND GROSS PROFIT (LOSS)

    Cost of revenues for the year ended December 31, 1998 totaled $36.5 million,
consisting of product costs of $33.5 million and supplier warrant costs of $3.0
million. Product costs represent the cost of airline tickets from
priceline.com's suppliers, net of the federal air transportation tax, segment
fees and passenger facility charges imposed in connection with the sale of
airline tickets. Supplier warrant costs represent a non-cash expense related to
the pro-rata amount of the Delta warrant earned prior to December 31, 1998, the
date on which the Delta warrant was amended. Priceline.com anticipates that it
will recognize additional supplier warrant costs in the amount of $1.6 million
in each of 1999 and 2000 in connection with additional warrants issued to a
participating airline in January 1999.

    Gross profit (loss), which is comprised of revenues less cost of revenues,
was $(1.3) million for the year ended December 31, 1998. Excluding the effect of
the non-cash supplier warrant costs, priceline.com would have had gross profit
of $1.7 million for the year ended December 31, 1998. Priceline.com is able to
manage the level of gross margins by controlling the price at which it will
cause offers to be fulfilled. Priceline.com has chosen to sell a substantial
number of tickets below its cost in order to increase airline and adaptive
marketing revenues, build a record of successful transactions, and enhance the
priceline.com brand. Because the fees generated by adaptive marketing programs
have historically involved no separate costs, adaptive marketing revenues have
had a disproportionately positive impact on priceline.com's total gross margin.
The Capital One adaptive marketing program accounted for all of priceline.com's
adaptive marketing revenues in 1998.

    OPERATING EXPENSES

    SUPPLIER START-UP WARRANT COSTS.  Supplier start up warrant costs for the
year ended December 31, 1998 totaled $58.0 million, or 164.5% of revenues.
Supplier start up warrant costs consist of a non-cash charge representing the
fair value of warrants issued to certain participating airlines in the
priceline.com service in connection with securing priceline.com's relationship
with those airlines.

    SALES AND MARKETING.  Sales and marketing expenses for the year ended
December 31, 1998 totaled $24.4 million, or 69.2% of revenues. Approximately 50%
of sales and marketing expenses were comprised of radio and newspaper
advertising expenses. The balance was comprised of (1) fees payable to a third
party service provider, which operates priceline.com's call center, (2) credit
card processing fees, (3) provisions for customer credit card charge-backs
(based upon a percentage reflecting priceline.com's historical experience), and
(4) compensation for priceline.com's sales and marketing personnel.

    SYSTEMS AND BUSINESS DEVELOPMENT.  Systems and business development expenses
for the year ended December 31, 1998 totaled $11.1 million, or 31.6% of
revenues. Systems and business development expenses are comprised primarily of
compensation to priceline.com's information technology and product development
staff and payments to outside contractors, data communications and other
expenses associated with operating priceline.com's Web site and, to a lesser
extent, depreciation on computer hardware and licensing fees for computer
software.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses for the
year ended December 31, 1998 totaled $18.0 million or 51.1% of revenues. General
and administrative expenses consist primarily of compensation for personnel,
fees for outside professionals, telecommunications and other overhead costs,
including occupancy expense. Also included is a one-time non-cash charge of $6.5
million relating to the issuance to Mr. Richard S. Braddock of a profits
interest with respect to 6.5 million units in priceline.com's predecessor,
priceline.com LLC. These units were granted to Mr. Braddock in connection with
his employment by priceline.com, and were subsequently converted into 8,125,000
shares of common stock.

    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.

- ------------------------

*   Adjusted Gross Profit and Adjusted Gross Margin reflect the elimination of
    non-cash charges associated with the supplier warrants.

    Revenues increased in each quarter since the commencement of operations in
April 1998. The increase in each quarter is due primarily to an increase in
airline ticket sales resulting from expanded inventory, improved fill rates and
an expanded customer base due to increased market awareness and acceptance of
the priceline.com service. In addition to the foregoing, (1) the increase in
revenue in the fourth quarter of 1998 is due to the addition of a significant
new airline partner and the inclusion for a full quarter of priceline.com's
Capital One adaptive marketing program, as well as, to a lesser extent, the
introduction of priceline.com's hotel room reservation service in October 1998;
and (2) the increase in revenue in the first and second quarters of 1999 is due
to increased customer offers, an increased supply of airline seats from our
existing airline partners and, to a lesser extent, the national launch of our
hotel room reservation service in March 1999.

    Cost of revenues, which consists of product costs and supplier warrant
costs, increased in each quarter of 1998 and the first and second quarters of
1999. Product costs, which are associated primarily with the amounts paid to
priceline.com's airline partners for airline tickets, net of federal air
transportation tax,

                                       38
<PAGE>
segment fees and passenger facility charges imposed in connection with the sale
of airline tickets, also increased each quarter in conjunction with increases in
total revenue. Supplier warrant costs consist of a non-cash expense related to
the pro-rata amount of the Delta warrant earned prior to December 31, 1998, the
date on which the Delta warrant agreement was amended. Excluding the effect of
the non-cash supplier warrant costs, priceline.com's gross profit would have
increased every quarter from the quarter ended June 30, 1998 to the quarter
ended June 30, 1999. The decreases in adjusted gross margins for the quarters
ended March 31, 1999 and June 30, 1999 were primarily due to the more rapid
growth of transaction-based revenues compared to fee-based revenues during those
periods. As a result of the differences in growth rates, our revenue mix changed
compared to prior periods with a greater percentage of revenues being
attributable to transaction revenues rather than fee-based revenues. Fee-based
revenues, such as adaptive marketing revenues, ancillary revenues and revenues
from financial services and automobiles have higher margins than transaction
revenues, which are derived from the spread between customer offers and the
product costs.

    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 exercise of employee stock options that give rise to social security
      and medicare payroll taxes;

    - 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

                                       39
<PAGE>
planned expenditures would have an immediate adverse effect on its business,
results of operations and financial condition.

    Priceline.com's limited operating history and rapid growth makes it
difficult for it to assess the impact of seasonal factors on its business.
Nevertheless, priceline.com expects its business to be subject to seasonal
fluctuations, reflecting a combination of seasonality trends for the products
and services offered by the 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 June 30, 1999 totaled approximately $246.6 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. On
April 1, 1999, priceline.com completed its initial public offering in which it
sold 10,000,000 shares of its common stock at a price of $16.00 per share,
raising $160.0 million in gross proceeds. Offering proceeds to priceline.com,
net of approximately $11.2 million in aggregate underwriters discounts and
commissions and $4.4 million in related expenses, were approximately $144.4
million. As of June 30, 1999, priceline.com had approximately $142.8 million in
cash and cash equivalents.

    In April 1998, priceline.com received proceeds from a loan of $1.0 million
for working capital from a high net worth individual who also was issued a
warrant to purchase 62,500 shares of common stock at an exercise price of $0.80
per share. This loan expires on April 15, 2003 and bears interest at a rate of
6.0%. The related warrant has been fully exercised, and as of the date of this
prospectus, the loan has been repaid.

    In April 1999, priceline.com made a $3.3 million loan to Mr. Richard S.
Braddock for the payment of taxes related to the issuance to Mr. Braddock of
8,125,000 shares of common stock in August 1998. The loan bears interest at
5.28% per annum. Interest is payable annually and principal is payable in
January 2004.

                                       40
<PAGE>
    In July 1999, priceline.com made a $6.0 million loan to Mr. Daniel H.
Schulman, pursuant to the terms of his employment agreement dated June 14, 1999.
The loan bears interest annually at 5.82% per annum. Subject to prepayment
obligations and to forgiveness in the event of certain changes of control,
death, or termination without cause, pursuant to the terms of the loan, accrued
interest and principal are payable in July 2004.


    Concurrent with this offering, priceline.com and certain of its stockholders
are making an offering of 5,500,000 shares of common stock, of which
priceline.com is offering to sell 2,000,000 shares of common stock.
Priceline.com expects the proceeds from the concurrent common stock offering to
be approximately $133.3 million (after deducting the estimated offering expenses
and underwriting discounts and commissions), based upon an assumed public
offering price of $70.00 per share.


    Net cash used in operating activities was $33.8 million for the six months
ended June 30, 1999. Net cash used in operating activities was primarily
attributable to net losses.

    Net cash used in investing activities was $20.6 million for the six months
ended June 30, 1999. Net cash used in investing activities was primarily related
to purchases of property and equipment.

    Net cash provided by financing activities was $143.6 million for the six
months ended June 30, 1999. Net cash provided by financing activities resulted
primarily from priceline.com's initial public offering of 10,000,000 shares of
its common stock, for which priceline.com received approximately $149.0 million
in cash, net of underwriting discounts and commissions on April 1, 1999.

    Priceline.com had commitments for capital expenditures as of June 30, 1999
of approximately $1.2 million. Capital expenditures were $11.3 million for the
six months ended June 30, 1999, and priceline.com expects such expenditures to
be at least $22.0 million for the full year of 1999. As a result of its rapid
growth, priceline.com expects to increase capital expenditures for purchased
software, internally developed software, computer equipment and leasehold
improvements.

    Priceline.com believes that, based upon its current operating plan, its
existing cash and cash equivalents, the net proceeds from its initial public
offering, the net proceeds from this offering and its concurrent common stock
offering and any cash generated from operations will be sufficient to fund its
operating activities, capital expenditures and other obligations through at
least the next three years. However, if during that period or thereafter
priceline.com is not successful in generating sufficient cash flow from
operations or in raising additional capital when required in sufficient amounts
and on terms acceptable to priceline.com, these failures could have a material
adverse effect on priceline.com's business, results of operations and financial
condition. If additional funds are raised through the issuance of equity
securities, the percentage ownership of its then-current stockholders would be
diluted.

MARKET-RELATED RISKS

    Priceline.com currently has no floating rate indebtedness, holds no
derivative instruments and does not earn significant foreign-sourced income.
Accordingly, changes in interest rates or currency exchange rates do not
generally have a direct effect on priceline.com's financial position. However,
changes in currency exchange rates may affect the cost of international airline
tickets and international hotel room reservations offered through the
priceline.com service, and so indirectly affect consumer demand for such
products and priceline.com's revenue. In addition, to the extent that changes in
interest rates and currency exchange rates affect general economic conditions,
priceline.com would also be affected by such changes.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, Statement of Financial Accounting Standards ("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

                                       41
<PAGE>
derivative and the resulting designation. Priceline.com is required to implement
the statement in the first quarter of fiscal 2001. 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.

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 $54.2 million. Utilization of priceline.com's net
operating loss carryforwards, which begin to expire in 2018, may be subject to
certain limitations under Section 382 of the Internal Revenue Code of 1986, as
amended. Priceline.com has provided a full valuation allowance on the deferred
tax asset, consisting primarily of net operating loss carryforwards, because of
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

    A federal air transportation tax is imposed upon the sale of airline tickets
and generally is collected by the airlines selling the tickets. The tax is based
upon a percentage of the cost of transportation, which was 9% for periods prior
to October 1, 1998 and 8% thereafter. Because of the unique pricing structures
employed in the priceline.com service, such as the amount paid by the customer
for a ticket being different than the amount charged by the airline for the same
ticket with the excess payment, if any, going to priceline.com as a charge for
the use of its proprietary business method, it is not clear how this federal tax
should be calculated when sales occur using the priceline.com service.
Priceline.com has been calculating this tax based on the fare paid to the
airline for a ticket, rather than the price paid by the customer. There is a
possibility that current law requires computation of the tax based on the price
paid by the customer to priceline.com. Due to the uncertainty of how the federal
air transportation tax applies to sales of airline tickets using the
priceline.com service, priceline.com has submitted a written request to the
United States Internal Revenue Service seeking a determination of
priceline.com's federal air transportation tax obligations. Such determination
may not be favorable and may require priceline.com to collect federal air
transportation tax on the total amount paid by consumers for air travel.

    If the determination of the Internal Revenue Service is unfavorable,
priceline.com could owe $766,339 in additional taxes as of June 30, 1999.
Priceline.com has accrued for such potential liability in its condensed balance
sheet as of June 30, 1999 and is providing for such potential liability on an
ongoing basis. Priceline.com has agreed to indemnify and hold harmless certain
of its participating airlines from any liability with respect to such taxes as
well as to secure the payment of such taxes by a letter of credit.

    NON-QUALIFIED STOCK OPTIONS


    Priceline.com currently has outstanding non-qualified stock options to
purchase 26,582,391 shares issued to various employees, consultants and
directors pursuant to the 1997 Omnibus Plan and the 1999 Omnibus Plan. The
options entitle holders to purchase common stock at a weighted average exercise
price of approximately $11.46 per share, subject to adjustment in accordance
with the 1997 Omnibus Plan and the 1999 Omnibus Plan. Upon exercise of an
option, priceline.com will be required to make payments on behalf of the option
holders for certain payroll related taxes such as Social Security and Medicare.
These payroll taxes will appear as a general and administrative expense on
priceline.com's income statement and


                                       42
<PAGE>
will amount to approximately 1.5% to 2.0% of the difference between the exercise
price and the then fair market value of the common stock at the time of
exercise. However, upon exercise of outstanding options, priceline.com will be
paid the exercise price of the options that are exercised. Priceline.com also
will be entitled to an income tax deduction equal to the sum of (1) the
difference between the exercise price of the option and the then fair market
value of the common stock at the time of exercise and (2) the total amount of
payroll related tax payments. As the calculation of the expense is directly
dependent upon priceline.com's stock price and the exercise of options is within
the sole discretion of the holder of the options, the amount and timing of the
expense and the timing of the corresponding income tax deduction are not
currently able to be determined and are not within the control of priceline.com.
Priceline.com estimates that, in connection with the exercise of outstanding
options pursuant to the option exercise program, in the third quarter of 1999 it
will (x) record expenses of approximately $1.3 million in respect of such
payroll related taxes; (y) increase additional paid-in capital by approximately
$944,000 in respect of the exercise price of such options; and (z) increase
common stock by approximately $7,700 in respect of the par value of the shares
purchased upon exercise of such options.

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 its 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 June 30, 1999. Such amounts have not been
material. The additional costs to make any other products or services Year 2000
compliant will be expensed as incurred, but are not expected to be material.

                                       43
<PAGE>
    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 reliability and safety because of the Year 2000 issue. All
of these factors could have a material adverse effect on its business, financial
condition and results of operations.

    CONTINGENCY PLANS

    Priceline.com has developed a contingency plan to address situations that it
believes would arise if it fails to be Year 2000 compliant. Priceline.com has
not developed a contingency plan to address situations that may result if its
suppliers are unable to achieve Year 2000 compliance. The cost of developing and
implementing such a plan, if necessary, could be material.

                                       44

                                    BUSINESS

OVERVIEW

    Priceline.com has pioneered a unique e-commerce pricing system known as a
"demand collection system" that enables consumers to use the Internet to save
money on a wide range of products and services while enabling sellers to
generate incremental revenue. Using a simple and compelling consumer
proposition--"name your price"--priceline.com collects consumer demand, in the
form of individual customer offers guaranteed by a credit card, for a particular
product or service at a price set by the customer. Priceline.com then either
communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether it can fulfill the
customer's offer on the basis of the pricing information and rules established
by the sellers. Consumers agree to hold their offers open for a specified period
of time and, once fulfilled, offers cannot be canceled. Priceline.com benefits
consumers by enabling them to save money, while at the same time benefitting
sellers by providing them with an effective revenue management tool capable of
identifying and capturing incremental revenues. By requiring consumers to be
flexible with respect to brands, sellers and product features, priceline.com
enables sellers to generate incremental revenue without disrupting their
existing distribution channels or retail pricing structures.


    Priceline.com commenced its service on April 6, 1998 with the sale of
leisure airline tickets and, during the period from launch through June 30,
1999, collected guaranteed offers for approximately 5.1 million airline tickets,
representing approximately $1.1 billion in total consumer demand, resulting in
sales of approximately 762,000 airline tickets, representing approximately
$165.2 million in revenue. During the six-month period ended June 30, 1999,
priceline.com collected guaranteed offers for approximately 1.8 million airline
tickets, representing approximately $697.5 million in total consumer demand.
This demand resulted in sales of approximately 627,000 airline tickets,
representing approximately $134.8 million in revenue. The number of offers that
priceline.com accepts is affected by a variety of factors, including the number
of reasonable offers received and the level of available inventory. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview."


    Since commencing service, the priceline.com business has grown significantly
and the priceline.com service now includes the following products and services:

    - leisure airline tickets, which now includes six domestic and 16
      international airline participants;

    - new automobiles, which was launched on a test basis in the New York
      metropolitan area in July 1998;

    - hotel room reservations, which was launched in October 1998, offers hotel
      rooms in substantially all major United States markets and includes as
      participants more than 10 leading national hotel chains; and

    - home financing services, which was launched in January 1999 with home
      mortgage services and now also includes home equity loans and refinancing
      services.

    Through the innovative use of "adaptive marketing programs," priceline.com
also markets customer acquisition programs for third parties. These programs
facilitate the completion of a higher percentage of successful transactions
through the priceline.com service while generating fee income for the company.
Priceline.com intends to continue to leverage the priceline.com brand by
expanding its product offerings to include rental cars, cruises, time shares,
vacation packages, personal and automobile loans, insurance and other financial
services products and by expanding our new car sales service to the entire U.S.
market. Priceline.com also is exploring expansion of its core "name your price"
business model to other areas of e-commerce, such as retail merchandise and the
consumer-to-consumer market.

    Priceline.com offers products and services that are provided by
participating sellers, many of whom are leaders in their industries. Twenty-two
domestic and international airlines currently participate in priceline.com's
leisure airline ticket service, including Delta, Northwest, Continental, TWA,
America West and leading international carriers. Participants in the
priceline.com hotel room reservation service include

                                       45
<PAGE>
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 home financing service, which is offered through a
joint marketing arrangement with LendingTree, an Internet-based home financing
service provider, includes a network of more than 30 participating lending
institutions.

    Priceline.com generates revenues in a variety of ways depending on the
product or service sold. With respect to its airline ticket and hotel room
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 recognizes as revenue the
customer's named price, net of taxes, and records as the cost of revenue, the
fare or rate charged by seller. With respect to priceline.com's automobile and
home financing services, a customer's offer is submitted directly to the
participating sellers who determine whether to fulfill the offer. With respect
to its automobile service, priceline.com earns a fixed fee from both the
customer and the seller after the transaction is consummated. With respect to
the home financing service, priceline.com receives marketing fees equal to a
percentage of the net revenue generated by the service, which is operated in
conjunction with LendingTree, Inc. For its adaptive marketing programs,
priceline.com earns fees 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 April 1999, among adult Americans, priceline.com was
the second most recognized e-commerce brand among the 20 leading brands included
in the survey and one of the most recognized Internet brands among the leading
brands included in the survey. Based on the study, priceline.com also believes
that, after only one year of operation, 91.1 million (or 46%) of all adult
Americans were aware of the priceline.com brand. The study also indicated that
awareness of the priceline.com brand increased over 14% since mid-1998.
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

                                       46
<PAGE>
commercial medium has been accompanied by a diversification in the type of
commerce that is conducted on the Internet and a proliferation in the types of
products and services available on the Internet.

    The Internet possesses a number of unique and commercially powerful
characteristics that differentiate it from traditional media: users communicate
or access information without geographic or temporal limitations; users access
dynamic and interactive content on a real-time basis; and users communicate and
interact instantaneously with a single individual or a group of individuals at
little or no cost. The Internet has created a dynamic and particularly
attractive medium for commerce, empowering consumers to gather more comparative
purchasing data than is feasible with traditional commerce systems, to shop in
ways that can be more convenient for them and to interact with sellers in many
new ways. As the Internet has become more accessible and widely used for
transactions, it has emerged as a primary business channel alongside the
telephone, paper-based communication and face-to-face interaction.

    LIMITATIONS OF TRADITIONAL PRICING MECHANISMS

    Under traditional retail pricing methods, sellers typically market products
to consumers under brand names at fixed retail prices. Alternatively, prices can
be established through auction processes. However, each of these forms of
seller-driven commerce has certain significant disadvantages for both sellers
and consumers. For example, in the retail pricing model, sellers who discount
prices to clear excess inventory, utilize excess capacity or increase sales
velocity, risk disruption of their existing distribution channels and damage to
their retail pricing structures. They also lose the opportunity to earn
incremental revenue from "free-riders," that is, consumers who would have been
prepared to pay the undiscounted price for the product or service, but
nevertheless obtain the benefit of the discounted price. Moreover, none of these
pricing methods allow sellers to consider the flexibility of potential buyers
before setting prices. Similarly, consumers are often forced to pay a higher
price when the seller is setting a fixed retail price for a product with added
features or under a specific brand, which the customer would otherwise have been
prepared to forgo for a lower price. Auctions force consumers to compete against
each other for the benefit of the seller, which always results in the product
being sold on the basis of the highest bid.

    While the Internet has become a significant medium for conducting business,
commerce presently conducted on the Internet is largely based upon traditional
pricing methods. Priceline.com believes that the vast information sharing and
communications power of the Internet creates an opportunity for significant
change in the way commerce or business is conducted.

THE PRICELINE.COM SOLUTION

    Priceline.com has developed a unique pricing system known as 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.

                                       47
<PAGE>
    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 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, Continental, 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

                                       48
<PAGE>
      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. 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 three 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, equity loans and
             refinancings, credit card balance consolidation and automobile and
             life insurance; and

        -  automobile sales and related financing.

      In these sectors, the priceline.com service currently offers leisure
      airline tickets, hotel rooms, home financings and 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 THE PRICELINE.COM BUSINESS MODEL. Priceline.com also intends to
      explore expansion of its core "name your price" business model to other
      areas of e-commerce. Priceline.com currently is evaluating the licensing
      of its business model to two new companies. One of these companies is
      developing a consumer-to-consumer transaction business in which buyers
      would make conditional purchase offers to acquire goods from other
      consumers. The other would enable consumers to use the Internet to name
      the price that they are willing to pay for retail merchandise, which they
      would pick up from participating retailers. However, priceline.com has not
      determined the structure of its relationship with these companies, which
      may include, among other things, licensing of the priceline.com brand and
      "name your price" business model and investment in such entities.

    - 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

                                       49
<PAGE>
      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 by telephone and provides
      customer service by telephone and e-mail 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 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.

                                       50
<PAGE>
THE PRICELINE.COM BUSINESS MODEL

    Priceline.com believes that its unique pricing system known as a "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.

    In addition to its unique revenue structure, the defining elements of the
priceline.com business model are the following:

    - the buyer specifies or accepts a RANGE OF SUBSTITUTABILITY among brands,
      product features and/or sellers; for example, he agrees to stay at any
      three-star hotel in a certain area, agrees to fly at any time of the day
      or agrees to purchase a new car from any factory-authorized dealer;

    - the buyer NAMES THE PRICE he is prepared to pay for the products or
      services within the specified range of substitutability;

    - the buyer GUARANTEES HIS OFFER for a specified time period by securing all
      or a portion of his potential payment for the product or service with a
      major credit card;

    - companies sell products or services at prices below their currently
      available retail prices using priceline.com as a BRAND SHIELD to protect
      their retail pricing structures and channels of distribution;

    - each guaranteed offer can be consummated with products or services from
      any of a GROUP OF SELLERS; and

    - offers made through priceline.com are held open for a specified period of
      time, and CANNOT BE CANCELED by either the seller or the buyer.

    The priceline.com consumer proposition is simple and compelling: realize
immediate savings by using the Internet to name your own price when you are
willing to be flexible about brands, product features and/or sellers. A central
premise of the priceline.com consumer proposition is that in many product and
service categories there are a significant number of consumers for whom brands,
product features or sellers are interchangeable, particularly if agreeing to a
substitution among brands or sellers will result in saving money. For example,
priceline.com believes that many leisure travelers are relatively indifferent
about the brand of major airline they fly. Similarly many consumers are
indifferent to which financial services company provides them with a credit card
or home mortgage. Priceline.com also believes that many consumers prefer not to
spend time and effort engaged in an evaluative process among similar products,
brands or sellers, which they consider to be substitutable. Finally,
priceline.com is appealing to some consumers because it does not charge a
customer to submit an offer, and priceline.com's Web site provides convenient
access, available 24 hours a day, seven days a week.

    Priceline.com believes that the collection of large volumes of consumer
demand is essential to building networks of multiple sellers. Priceline.com also
believes that it is important that all of the demand

                                       51
<PAGE>
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.
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. The priceline.com service now includes the sale
of new automobiles, hotel room reservations and home financing services.
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. Priceline.com also intends to explore
expansion of its core "name your price" business model to other areas of
e-commerce, such as the consumer-to-consumer market.

    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

                                       52
<PAGE>
since the launch of the business, from an initial group of two domestic airlines
and four international airlines, to a total of six domestic airlines and 16
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;

    - 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, plus applicable taxes and standard processing fees, and
the ticket is delivered to the customer by the delivery method specified by the
customer. Approximately 94% of domestic tickets issued through priceline.com are
electronic tickets. Priceline.com earns the spread, if any, between the
customer's offered price and the cost to purchase the ticket from the airline,
and the handling fee charge paid by the customer on each ticket.

    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 room reservation service currently is

                                       53
<PAGE>
available in substantially all major cities and metropolitan areas in the United
States. Seller participants in the hotel room 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 room reservation service operates in a manner similar
to its airline ticket service. Consumers are required to accept certain
trade-offs with respect to brands or product features in return for saving
money. For example, consumers are required to accept a reservation in any hotel
within a specified geographic area within a designated "class" of service (1, 2,
3, 4 or 5-star) and must accept limitations on changes and cancellations.
Priceline.com determines the class of service for each participating hotel based
upon published industry reports, the amenities available at each property and
other factors such as age and decor. As with the airline ticket service, the
target market for priceline.com's hotel room reservation service is the leisure
travel market.

    Consumers can make offers for a hotel room reservation through the
priceline.com Web site. 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 room 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
room 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 room 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 room 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 FINANCING SERVICES.  Priceline.com introduced its home financing
service in January 1999. Priceline.com's financing 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 home financing
service on the priceline.com Web site and for consumer marketing. LendingTree
serves as the back-end processing system, which presents offers received through
priceline.com to multiple mortgage lending institutions for consideration. There
are currently more than 30 lenders participating in

                                       54
<PAGE>

the home financing services through LendingTree. See "--Strategic
Alliances--Home Financing Alliances."


    To obtain a home mortgage, refinancing a home equity loan through the
priceline.com service, consumers access the priceline.com Web site and specify
the amount of the loan, the term, the interest rate and the points that 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 good-faith
deposit of $200 that is applied towards closing costs. The good-faith deposit is
charged by a lender only when a customer's offer is accepted. Priceline.com does
not charge the customer any fees for the use of its home financing services.
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 consumers whether their
offer has been accepted within six business hours, between the hours of 8:00
a.m. and 8:00 p.m., Eastern Standard Time. If a customer's offer is not accepted
within six business hours, priceline.com notifies the customer if it has
received any counter-offers from participating lenders. Participating lenders
may submit counter-offers for up to two business days following the customer's
offer. Customers may check the status of any counter-offers by accessing the
priceline.com Web site. Priceline.com generates revenues with respect to its
home financing service in the form of marketing fees paid directly by
LendingTree.

    Priceline.com is exploring the possibility of entering into a joint venture
with a subsidiary of a federally chartered thrift institution that would offer
to provide mortgage loans through the priceline.com service. Priceline.com
currently expects that such joint venture would participate in the priceline.com
service along with other mortgage lenders in the LendingTree network.

    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 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, automobile 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 its new car sales service on a test basis in the
New York metropolitan area in July 1998. Priceline.com utilized the New York
market to learn more about automobile sales over the Internet and to develop
product features and systems support. In July 1999, priceline.com launched a
similar test in the Tampa, Florida market and expects to expand further in the
state of Florida, as well as into the states of California and Michigan during
the third quarter of 1999. Based on published industry data, the New York
metropolitan area represents approximately 10% of all consumer demand for new
automobiles in the United States, while California represents approximately 11%
and Florida represents approximately 9%. Additionally, the Detroit metropolitan
area provides access to the three largest U.S. auto-makers. Subject to achieving
positive results in these markets and receipt of appropriate state

                                       55
<PAGE>
regulatory approvals and authorizations necessary to conduct our new car sales
service, priceline.com expects to become operational in the 48 contiguous states
during the first quarter of 2000. Priceline.com recently entered into a
co-marketing agreement with AutoNation, Inc., a leading national automotive
retailer. The agreement initially provides priceline.com with access to
AutoNation's inventory and dealerships in the Tampa, Florida market and provides
for expansion into other markets in the future.

    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, the
customer identifies the exact vehicle desired to be purchased or leased,
including the make, model and specified options, the geographic area in which
the customer is willing to pick up the vehicle and the purchase price or lease
price the customer is willing to pay. All sales are made through factory
authorized dealers. 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.
Additionally, priceline.com also supplies an estimated market price, based on
recent sales of the selected vehicle.

    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.

    Currently, priceline.com does not offer financing arrangements through its
new car sales service. However, to assist consumers in determining whether they
can afford a particular vehicle, or what purchase price to offer, we provide
estimated month payment calculations, a "budget work-sheet" and a financing
calculator on our Web site. Priceline.com also allows consumers to request
financing from the accepting factory authorized dealer and to condition their
offers on obtaining such financing.

    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 cars 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 one round-trip airline
ticket can immediately increase the amount of his offer by $40 by applying
online for a First USA credit card. If the customer obtains the requested
ticket, he still pays only the amount contained in his original offer, plus
applicable taxes and standard processing fees. 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 First USA credit card,
priceline.com would increase the customer's offer by up to an additional $40 to
enable the customer a greater chance of purchasing the ticket. If priceline.com
is able to purchase the ticket for $240 or less, the customer would still only
have to pay his original offer price of $200, plus applicable taxes and fees.

    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.

    During 1998 and the first quarter of 1999, our adaptive marketing revenues
were derived primarily from fees paid by Capital One Bank for qualifying credit
card applications submitted over the priceline.com service in connection with
customer offers for airline tickets. Effective May 1, 1999, our relationship
with Capital One ended. Since that time, our credit card adaptive marketing
program revenues have been attributable to our adaptive marketing relationship
with First USA Bank, a leading national credit card issuer. Under the First USA
adaptive marketing program, priceline.com enables its customers to increase the
amount of their offers by applying online for a First USA credit card and offers
other promotions linked to the First USA customer acquisition program. The fee
structure of the First USA program is based on different factors than the
factors that were applicable under the Capital One program and the First USA
program is subject to certain early termination and repricing rights of First
USA.

    Priceline.com also has an adaptive marketing agreement with E*TRADE, under
which E*TRADE compensates priceline.com for offering priceline.com customers the
opportunity to open an account with E*TRADE while visiting or making an offer on
the priceline.com Web site. While the program originally related to
priceline.com's initial public offering, it now applies to offers by customers
for products and services over the priceline.com service. The E*TRADE adaptive
marketing program is currently operated under an oral agreement and may be
terminated at any time.

    Priceline.com recently has entered into adaptive marketing agreements with
Sprint Communications Company L.P., Discover Financial Services, Inc. and
Earthlink Network, Inc. The Sprint agreement is a short-term agreement under
which priceline.com, during a twelve-week test program, will earn fees from
Sprint in connection with customer agreeing to switch their long distance
telephone service to Sprint. Priceline.com and Sprint are currently in the
process of defining the program and the launch date has not yet been determined.
We are also evaluating similar programs with other long distance carriers.

    Under the Discover adaptive marketing program, selected customers will be
able to increase the amount of their offers by a specified amount by applying
online for a Discover credit card through the priceline.com service.
Priceline.com will receive a fee from Discover Financial Services for each
qualifying credit card application submitted through the priceline.com service.
Priceline.com will also receive a fee

                                       57
<PAGE>
for any qualifying upgrade of an established Discover credit card account
submitted through the priceline.com service. The Discover adaptive marketing
program is expected to be implemented during the third quarter of 1999 and will
be offered to selected customers who have already participated, or who have
declined participation, in the First USA adaptive marketing program.

    Under priceline.com's adaptive marketing program with EarthLink Network,
Inc., an internet service provider, priceline.com will earn fees when its
customers open accounts with EarthLink and upon such accounts being open for a
specified period of time. No specific date has been set for the launch of the
EarthLink program.

    In addition, Priceline.com is exploring and has taken steps to expand its
adaptive marketing programs into a wide range of other products and services for
its customers. See "Risk Factors--We are Dependent on Adaptive Marketing
Programs" and "--Strategic Alliances--Adaptive Marketing Alliances."

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 June 30,
1999, priceline.com incurred $59.7 million for sales and marketing expense. It
intends to continue to pursue an aggressive marketing strategy designed to
promote brand awareness and the concept that consumers can save money on a wide
range of products and services through priceline.com. Underlying priceline.com's
marketing strategy is the company's belief that its target market is all
consumers, not just Internet-savvy consumers. Substantially all of such spending
has been for radio and newspaper advertising. Priceline.com's campaign features
the actor William Shatner as its spokesperson.

    Priceline.com supplements its paid advertising and promotion with targeted
media coverage. Priceline.com has been featured in hundreds of news stories in
national publications such as THE NEW YORK TIMES, THE WALL STREET JOURNAL AND
USA TODAY, reflecting the intuitive appeal of the priceline.com business model
and its strong word-of-mouth support. In addition, priceline.com engages in
grass roots marketing such as promotional events on college campuses and
co-promotions with popular media such as MTV.

    Priceline.com believes that the priceline.com service has achieved
widespread brand awareness. Based upon the results of an independent research
study conducted for priceline.com, the company believes that, as of April 1999,
among adult Americans, priceline.com was the second most recognized e-commerce
brand among the 20 leading brands included in the survey and one of the most
recognized Internet brands among the leading brands included in the survey.
Based on the study, priceline.com also believes that, after only one year of
operations, 91.1 million (or 46%) of all adult Americans were aware of the
priceline.com brand. 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 six
domestic and 16 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;

                                       58
<PAGE>
    - consumers must be willing to fly on any participating airline;

    - consumers must be willing to depart at any time after 6 a.m. and land any
      time before 10 p.m. on the requested dates;

    - all offers must be guaranteed with a major credit card; and

    - consumers are limited in their ability to make multiple offers with
      respect to the same travel itinerary.

    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. Priceline.com's agreement with Delta, subject to
various exceptions, requires Delta's approval of the addition of new carriers to
the priceline.com service, restricts the routes for which tickets may be offered
by specified carriers through the priceline.com service and imposes limitations
on the code share arrangements of specified carriers. Delta also may require the
exclusion of specific markets in order for certain other airlines to
participate. These provisions could limit priceline.com's ability to expand its
airline ticket service. In addition, priceline.com's ability to transfer or
license its intellectual property to other travel providers is limited in the
manner set forth in the agreement.

    In connection with the Airline Participation Agreement with Delta,
priceline.com also issued a warrant to Delta to purchase up to 18,619,402 shares
of common stock at an exercise price of approximately $0.93 per share. The Delta
warrant will become exercisable at the earlier of December 31, 2005, or Delta's
achievement of certain performance thresholds of ticket sales.

    Priceline.com also has issued to several participating airlines warrants to
purchase an aggregate of 3,187,500 shares of common stock, comprised of warrants
to purchase 937,500 shares of common stock at an exercise price of $3.20 per
share, warrants to purchase 1,250,000 shares of common stock at an exercise
price of $6.40 per share and warrants to purchase 1,000,000 shares of common
stock at an exercise price of approximately $97.41 per share. The warrants
having an exercise price of $3.20 per share become exercisable on October 28,
1999. With respect to the warrants having an exercise price of $6.40 per share,
warrants relating to one-half of the underlying shares become exercisable on
December 31, 1999, and warrants relating to the remaining underlying shares
become exercisable on December 31, 2000, subject to earlier termination of such
warrants in the circumstances identified in the warrant agreement. The warrants
having an exercise price of $97.41 per share become exercisable upon the earlier
of July 16, 2004 or the airline's achievement of various performance thresholds
based upon ticket sales.

    HOME FINANCING ALLIANCES

    In connection with priceline.com's home financing 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 participating 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

                                       59
<PAGE>
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.

    Priceline.com is exploring the possibility of entering into a joint venture
with a subsidiary of a federally chartered thrift institution that would offer
to provide mortgage loans through the priceline.com service. Priceline.com
currently expects that such joint venture would participate in the priceline.com
service along with other mortgage lenders in the LendingTree network.

    HOTEL ALLIANCES

    In connection with priceline.com's hotel service, priceline.com has entered
into letter agreements with 39 hotel groups, which cover numerous brands and
include several of the leading national 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.

    AUTOMOTIVE ALLIANCE

    Priceline.com has entered into a co-marketing agreement with AutoNation,
Inc., a leading national automotive retailer. Under the terms of the
co-marketing agreement, consumer offers for automobiles submitted through the
priceline.com service will be offered to AutoNation dealers first. If no
AutoNation dealers accept a customer's offer, such offer will be submitted to
other dealers in the market. The service is being offered initially in the Tampa
and St. Petersburg, Florida markets, with plans to expand to additional markets
nationwide.

    ADAPTIVE MARKETING ALLIANCES

    During 1998 and the first quarter of 1999, our adaptive marketing revenues
were derived primarily from fees paid by Capital One Bank for qualifying credit
card applications submitted over the priceline.com service in connection with
customer offers for airline tickets. Effective May 1, 1999, our relationship
with Capital One ended. Since that time, our credit card adaptive marketing
program revenues have been attributable to our adaptive marketing relationship
with First USA Bank, a leading national credit card issuer. Under the First USA
adaptive marketing program, priceline.com enables its customers to increase the
amount of their offers by a specified amount by applying online for a First USA
credit card and offers other promotions linked to the First USA customer
acquisition program. The fee structure of the First USA program is based on
different factors than the factors that were applicable under the Capital One
program. Under the First USA program, priceline.com earns fees (1) upon the
opening of credit card accounts originated through the priceline.com service, up
to a specified maximum amount of five million accounts, subject to reduction
under certain circumstances by First USA; (2) upon the activation of credit card
accounts acquired for First USA through the priceline.com service and based upon
the use of such accounts; and (3) for transfers of balances from other credit
cards to First USA credit cards through the priceline.com service.

    The First USA agreement has a term of five years, subject to certain earlier
termination and repricing rights of First USA. For example, subject to
priceline.com's rights of renegotiation, First USA has the right to terminate
the agreement after one year (and earlier under certain circumstances) if its
financial returns under the adaptive marketing program are not at least
equivalent to certain agreed upon levels. In

                                       60
<PAGE>
addition, a portion of the fees earned under the First USA program is required
to be reinvested in program incentives. The full financial statement impact of
the shift from the Capital One adaptive marketing program to the First USA
adaptive marketing program will not be known until completion of future periods.

    Priceline.com also has an adaptive marketing agreement with E*TRADE, under
which E*TRADE compensates priceline.com for offering priceline.com customers the
opportunity to open an account with E*TRADE while visiting or making an offer on
the priceline.com Web site. While the program originally related to
priceline.com's initial public offering, it now applies to offers by customers
for products and services over the priceline.com service. The E*TRADE adaptive
marketing program is currently operated under an oral agreement.

    Priceline.com recently has entered into adaptive marketing agreements with
Sprint Communications Company L.P., Discover Financial Services, Inc. and
Earthlink Network, Inc. The Sprint agreement is a short-term agreement under
which priceline.com, during a twelve-week test program, will earn fees from
Sprint in connection with customers agreeing to switch their long distance
telephone service to Sprint. Priceline.com and Sprint are currently in the
process of defining the program and the launch date has not yet been determined.
We are also evaluating similar programs with other long distance carriers.

    Under the Discover adaptive marketing program, selected customers will be
able to increase the amount of their offers by a specified amount by applying
online for a Discover credit card through the priceline.com service.
Priceline.com will receive a fee from Discover Financial Services for each
qualifying credit card application submitted through the priceline.com service.
Priceline.com will also receive a fee for any qualifying upgrade of an
established Discover credit card account submitted through the priceline.com
service. The Discover adaptive marketing program is expected to be implemented
during the third quarter of 1999 and will be offered to selected customers who
have already participated, or who have declined participation, in the First USA
adaptive marketing program.

    Under priceline.com's adaptive marketing program with EarthLink Network,
Inc., an internet service provider, priceline.com will earn fees when its
customers open accounts with EarthLink and upon such accounts being open for a
specified period of time. No specific date has been set for the launch of the
EarthLink program.

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;

    - traditional travel agencies;

    - consolidators and wholesalers of airline tickets and other travel
      products, including online consolidators such as Cheaptickets.com;

    - 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 AutoNation, Auto-by-Tel and Microsoft's
CarPoint. With respect to financial service products, priceline.com's
competitors include:

    - banks and other financial institutions;

                                       61
<PAGE>
    - online and traditional mortgage and insurance brokers, including
      mortgage.com, Quicken Mortgage, E-Loan and iOwn, Inc.; 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 Amazon.com, 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 room 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

                                       62
<PAGE>
power supply system and generator and redundant servers at its Stamford,
Connecticut headquarters to provide service capability if the Exodus site fails.

    Priceline.com also offers phone service through its toll-free number,
1-800-Priceline, which allows consumers who do not have access to a computer to
phone in their orders. 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. Because priceline.com is an
Internet business, it intends to phase out its telephone ordering and credit
card submission services over time and, in the future, will use its toll-free
number only to provide customer service.

INTELLECTUAL PROPERTY

    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 three issued United States patents, No.
5,794,207, No. 5,797,127 and No. 5,897,260, as well as 25 pending United States
patent applications and four pending international patent application.
Priceline.com is in the process of filing at least three more patent
applications, with an ongoing program for identifying and protecting new
inventions. Priceline.com's core business method patent is directed to a unique
buyer-driven commerce system using a computer to collect credit card-backed or
other financial account-backed conditional purchase offers to present to
multiple sellers, receive one or more acceptances or fulfillments of these
offers, and use the credit card or other financial account to provide a payment
to one or more of the sellers. The pending patent applications are directed to
various operational features of the system, as well as to product-specific
enhancements.

    While priceline.com believes that its core buyer-driven commerce patent,
together with its pending patent applications, help to protect the priceline.com
business, there can be no assurance that (1) the core buyer-driven patent or any
other patent can be successfully defended against challenges by third parties;
(2) the pending patent applications will result in the issuance of patents; (3)
competitors or potential competitors of priceline.com will not devise new
methods of competing with the company that are not covered by priceline.com's
patent or patent applications; (4) because of variations in the application of
our business model to each of our products and services, our core buyer-driven
commerce patent may not be effective in preventing one or more third parties
from utilizing a copycat business model to offer the same product or service in
one or more categories; (5) new prior art will not be discovered which may
diminish the value of or invalidate an issued patent; or (6) 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 appears to use customer-offer based transaction models.

    Walker Digital currently owns the assets and intellectual property related
to two new areas of e-commerce into which priceline.com may expand its "name
your price" business model, one involving consumer-to-consumer sales and the
other involving the sale of retail merchandise. Priceline.com may license its
brand name and "name your price" business model to two new companies formed to
develop these businesses. Walker Digital may contribute assets and intellectual
property to these companies in return for an equity interest in these companies.

                                       63
<PAGE>
    Walker Digital owns the intellectual property rights underlying the
technology associated with priceline.com's adaptive marketing programs. Walker
Digital has licensed to priceline.com the right to use these intellectual
property rights under a perpetual, non-exclusive, royalty-free license
agreement. Walker Digital has several pending United States patent applications
directed to different aspects of the processes and technology supporting
adaptive marketing programs.

    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.com
is registered as a "seller of travel" under the California Seller of Travel Act
and is a member of the Airlines Reporting Corporation. In addition, a number of
state travel laws and regulations require compliance with specific disclosure,
bond and/or other requirements.

    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. With
the planned expansion of its new automobile service from the New York
metropolitan area to all 48 contiguous states, priceline.com will attempt to
register as an automobile broker/dealer in the jurisdictions where registration
is required provided that it can reasonably comply with the requirements for
registration imposed by each jurisdiction. However, priceline.com may not be
able to register in all states. For example, priceline.com will not be able to
register in a jurisdiction that requires a dealer zoned lot or a franchise
agreement with manufacturers of the automobiles to be sold. Priceline.com will
work with the regulators of the various jurisdictions to obtain waivers of such
requirements, but it may not be successful in its efforts.


    In jurisdictions where priceline.com cannot obtain registration, it is
possible that state regulatory bodies could take a strict enforcement position
and priceline.com may be unable to continue to make its new automobile services
available in those jurisdictions.


                                       64

    HOME FINANCING SERVICES

    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 financing service in January 1999.
LendingTree serves as the back-end processing system, which presents offers
received through the priceline.com service to multiple mortgage lending
institutions for consideration, for all of priceline.com's home financing
services,
Priceline.com provides and is responsible for maintaining the home financing
service on its Web site and develops and purchases all advertising. LendingTree
compensates 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 back-end processing system, which presents offers
we receive to multiple mortgage lending institutions for consideration, for the
home financing service on priceline.com's Web site and is responsible for
maintaining the necessary and appropriate state registrations and licenses
associated with LendingTree's 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.

    Priceline.com is exploring the possibility of acquiring a minority interest
in, and licensing the priceline.com name and business model to, a newly formed
subsidiary of a federally chartered savings and loan association. This entity
may be known as "priceline.mortgage.com" and also may serve as an entity that
could accept mortgage applications or mortgage qualification loans.

    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 also is 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.

                                       65
<PAGE>
    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
recently received a notice from the United States Patent and Trademark Office
that an undisclosed patent applicant, believed by priceline.com to be Woolston,
is seeking to provoke an interference on priceline.com's core buyer-driven
commerce patent. Priceline.com currently is awaiting information from the Patent
Office regarding whether it will initiate an interference proceeding concerning
Woolston's patent application and priceline.com's core buyer-driven commerce
patent. An interference is an administrative proceeding instituted in the Patent
Office to determine questions of patentability and priority of invention between
two or more parties claiming the same patentable invention. There is no
statutory period within which the Patent Office must act on an interference
request. If an interference is declared and proceeds through a final hearing in
the Patent Office, a final judgment is made by the Patent Office as to
inventorship. Following such final judgment, appeals could be made in Federal
court. While there can be no certainty as to time periods, interference
proceedings typically take years to resolve.


    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from the
priceline.com core buyer-driven commerce patent. In order to make this showing,
he would have to prove, among other things, that he invented the subject matter
of the priceline.com claims before the inventors of the priceline.com patent. If
the Patent Office were to find that Woolston's patent application supported the
copied priceline.com claims, it would resolve the interference by awarding
inventorship to the party with the earliest proven date of invention. Woolston
announced in February 1999 an agreement to license his issued patent and pending
patent applications to the owner of a competing Internet travel service.

    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While

                                       66
<PAGE>
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 and pay damages from the date such patent issued at a
cost which could significantly adversely affect priceline.com's business. If
Woolston prevailed in both an interference and an infringement action, then
priceline.com could be enjoined from conducting business through the
priceline.com service to the extent covered by the patent claims awarded to
Woolston. In addition, defense of the interference action may be expensive and
may divert management attention away from priceline.com's business.

    On January 19, 1999, a lawsuit was filed in the United States District Court
for the Northern District of California by Marketel International, Inc., a
California corporation, under the caption MARKETEL INTERNATIONAL INC. V.
PRICELINE.COM ET. AL.,No. C-99-1061 (N.D. CA 1999), against priceline.com,
Priceline Travel, Walker Asset Management, Walker Digital, Mr. Jay S. Walker,
priceline.com's Founder and Vice Chairman, and Mr. Andre Jaeckle, an individual
who made a $1.0 million loan to priceline.com bearing interest at a rate of 6%
per year and, in connection with the loan, received warrants, which have
subsequently been fully exercised, to purchase 62,500 shares of our common
stock. On February 22, 1999, Marketel filed an amended complaint, and March 17,
1999, Marketel filed a second amended complaint. The second amended complaint
includes as defendants, Mr. Timothy G. Brier, our Executive Vice President,
Travel, Mr. Bruce Schneier, and an individual and consultant to Walker Digital,
and Mr. James Jorasch, an individual and employee of Walker Digital, and 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 second amended
complaint, Marketel alleges, among other things, that the defendants conspired
to misappropriate Marketel's business model, which it describes as a
buyer-driven electronic marketplace for travel services and its appurtenant
techniques, market research, forms, plans and processes, and which an executive
of Marketel allegedly provided to Messrs. Walker and Jaeckle in confidence
approximately ten years ago. The second amended complaint also alleges that
three former Marketel employees are the actual sole inventors or co-inventors of
U.S. patent No. 5794207, which was issued on August 11, 1998 with Jay S. Walker,
Bruce Schneier and James Jorasch listed as the inventors and which patent has
been assigned to priceline.com. Marketel asks that the patent's inventorship be
corrected accordingly.

    Based upon publicly available information, priceline.com believes that
Marketel's fax and fee-based business was launched in 1991 and ceased operations
seven months later. Priceline.com's Internet-based model was independently
developed by Walker Digital and priceline.com, and practiced by priceline.com
starting in 1998. Based on publicly available information and Marketel's second
amended 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 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, February 10, 1999 and March 31, 1999, the defendants
filed their answer, amended answer and answer to second amended complaint,
respectively, in which they denied the material allegations of liability in the
complaints. Priceline.com and all other defendants strongly dispute the material
legal and factual allegations contained in Marketel's second amended complaint
and believe that

                                       67
<PAGE>
the second amended complaint is without merit. Priceline.com intends to defend
vigorously against the action. Since May 28, 1999, there has been a discovery
stay in effect, which was caused by the withdrawal of Marketel's counsel.
Marketel has retained new counsel, and priceline.com now anticipates moving
forward with discovery. Defending the lawsuit may involve significant expense
and, due to the inherent uncertainties of litigation, there can be no certainty
as to the ultimate outcome. Pursuant to the terms of the indemnification
obligations contained in the Purchase and Intercompany Agreement with Walker
Digital, Walker Digital has agreed to indemnify priceline.com for damages,
liability and legal expenses incurred in connection with the Marketel
litigation.

    From time to time priceline.com has been and expects to continue to be
subject to legal proceedings and claims in the ordinary course of business,
including claims of alleged infringement of third party intellectual property
rights by the company. Such claims, even if not meritorious, could result in the
expenditure of significant financial and managerial resources.

EMPLOYEES

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 40,000 square feet of leased office space located in Stamford,
Connecticut. Priceline.com is subleasing this office space from Walker Digital
on a month-to-month basis. Priceline.com also has guaranteed Walker Digital's
obligations under a lease of office space in New York City that is used by both
companies. Priceline.com anticipates that it will require additional space
within the next 12 months to accommodate its anticipated growth and that
suitable office space will be available on commercially reasonable terms.
Priceline.com currently is negotiating a lease of new premises in Connecticut.
The premises are substantially larger than priceline.com's current premises and,
if a lease is signed, priceline.com's rental expense is likely to increase
significantly.

STOCK BASED PLANS


    Pursuant to the priceline.com Incorporated 1997 Omnibus Plan, priceline.com
has granted awards of options to certain officers, other employees, consultants
and directors of priceline.com. The maximum number of shares of common stock
reserved for the grant or settlement of awards under the 1997 Omnibus Plan is
23,875,000, subject to adjustment as provided therein. Of such number,
22,752,886 options covering shares of common stock were outstanding under the
1997 Omnibus Plan as of August 10, 1999. In February 1999, priceline.com
established the priceline.com Incorporated 1999 Omnibus Plan, pursuant to which
awards will be made to certain officers, other employees, consultants and
directors of priceline.com from time to time following the consummation of this
offering. The maximum number of shares of common stock reserved for the grant or
settlement of awards under the 1999 Omnibus Plan is 9,375,000, subject to
adjustment. Of such number, options covering 3,829,505 shares of common stock
were outstanding under the 1999 Omnibus Plan as of August 10, 1999.


    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

                                       74
<PAGE>
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 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

                                       75
<PAGE>
provisions of agreements evidencing awards; and to make all other determinations
deemed necessary or advisable for the administration of the 1997 Omnibus Plan.

    The compensation committee may, in its absolute discretion, without
amendment to the 1997 Omnibus Plan, (a) accelerate the date on which any option
or stand-alone appreciation right granted under the 1997 Omnibus Plan becomes
exercisable, waive or amend the operation of provisions respecting exercise
after termination of employment or otherwise adjust any of the terms of such
option or stand-alone appreciation right, (b) accelerate the vesting or waive
any condition imposed with respect to any restricted stock, phantom stock or
other awards and (c) otherwise adjust any of the terms applicable to any award.

    AWARDS UNDER THE 1997 OMNIBUS PLAN

    STOCK OPTIONS; STOCK APPRECIATION RIGHTS

    Unless otherwise determined by the compensation committee, options granted
pursuant to the 1997 Omnibus Plan will become exercisable ratably over three
years commencing on the first anniversary of the date of grant, but in no event
may an option be exercised more than 10 years following the date of its grant.
The "option exercise price," which is the purchase price per share payable upon
the exercise of an option, will be established by the compensation committee;
PROVIDED, HOWEVER, that incentive stock options may not have an exercise price
less than the fair market value of a share of common stock on the date of grant.
The option exercise price is payable by any one of the following methods or a
combination thereof, to the extent permitted by the compensation committee: (1)
in cash or by personal check, certified check, bank cashier's check or wire
transfer; (2) subject to the approval of the compensation committee, in common
stock owned by the participant for at least six months prior to the date of
exercise and valued at their fair market value on the effective date of such
exercise; or (3) subject to the approval of the compensation committee, by such
other provision as the compensation committee may from time to time authorize.

    The compensation committee also has the authority to specify, at the time of
grant or, with respect to non-qualified stock options at or after the time of
grant, that a participant shall be granted a new non-qualified stock option,
otherwise known as a "reload option," for a number of shares of common stock
equal to the number of shares of common stock surrendered by the participant
upon exercise of all or a part of an option in the manner described above,
subject to the availability of common stock under the 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

                                       76
<PAGE>
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.

    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

                                       77
<PAGE>
90 days after termination of employment) or if the optionee subsequently engages
in a "disqualifying disposition," as described below.

    A sale or exchange by an optionee of shares acquired upon the exercise of an
incentive stock option more than one year after the transfer of the shares to
such optionee and more than two years after the date of grant of the incentive
stock option will result in any difference between the net sale proceeds and the
exercise price being treated as long-term capital gain or loss to the optionee.
If such sale or exchange takes place within two years after the date of grant of
the incentive stock option or within one year from the date of transfer of the
incentive stock option shares to the optionee, such sale or exchange will
generally constitute a "disqualifying disposition" of such shares that will have
the following results: any excess of (x) the lesser of (1) the fair market value
of the shares at the time of exercise of the incentive stock option and (2) the
amount realized on such disqualifying disposition of the shares over (y) the
option exercise price of such shares, will be ordinary income to the optionee,
subject to applicable withholding taxes, and priceline.com will be entitled to a
tax deduction in the amount of such income. Any further gain or loss after the
date of exercise generally will qualify as capital gain or loss and will not
result in any deduction by priceline.com.

    APPRECIATION RIGHTS

    The grant of appreciation rights has no federal income tax consequences at
the time of grant. Upon the exercise of appreciation rights, the amount received
is generally taxable as ordinary income, and priceline.com is entitled to a
corresponding deduction.

    RESTRICTED STOCK

    A grantee will not recognize any income upon the receipt of restricted stock
unless the holder elects under Section 83(b) of the Code, within thirty days of
such receipt, to recognize ordinary income in an amount equal to the fair market
value of the restricted stock at the time of receipt, less any amount paid for
the shares. If the election is made, the holder will not be allowed a deduction
for amounts subsequently required to be returned to priceline.com. If the
election is not made, the holder will generally recognize ordinary income, on
the date that the restrictions to which the restricted stock are subject are
removed, in an amount equal to the fair market value of such shares on such
date, less any amount paid for the shares. At the time the holder recognizes
ordinary income, priceline.com generally will be entitled to a deduction in the
same amount.

    Generally, upon a sale or other disposition of restricted stock with respect
to which the holder has recognized ordinary income, for example, if a Section
83(b) election was previously made or the restrictions were previously removed,
the holder will recognize capital gain or loss in an amount equal to the
difference between the amount realized on such sale or other disposition and the
holder's basis in such shares.

    PHANTOM STOCK

    The grant of phantom stock has no federal income tax consequences at the
time of grant. Upon the receipt of payment, the amount received is generally
taxable as ordinary income, and priceline.com is entitled to a corresponding
deduction.

    OTHER TYPES OF AWARDS

    The grant of any other stock-based award generally will not result in income
for the grantee or in a tax deduction for priceline.com. Upon the settlement of
such an award, the grantee will recognize ordinary income equal to the aggregate
value of the payment received, and priceline.com generally will be entitled to a
tax deduction in the same amount.

PRICELINE.COM INCORPORATED 1999 OMNIBUS PLAN

    In February 1999, priceline.com established the 1999 Omnibus Plan. The 1999
Omnibus Plan is intended to promote the long-term financial interests and growth
of priceline.com by providing employees of priceline.com with appropriate
incentives and rewards to encourage them to enter into and continue in the
employ of the company and to acquire a proprietary interest in the long-term
success of the company; and to reward the performance of individual officers,
other employees, consultants and directors in fulfilling their responsibilities
for long-range achievements.

    GENERAL

    The 1999 Omnibus Plan provides for the granting of awards to such officers,
other employees, consultants and directors of priceline.com and its affiliates
as the compensation committee, which is the committee of the board of directors
appointed to administer the Plan may select from time to time. Awards under the
1999 Omnibus Plan may be made in the form of incentive stock options,
non-qualified stock options, restricted stock or other awards.

    The maximum number of shares of common stock reserved for the grant or
settlement of awards under the 1999 Omnibus Plan is 9,375,000 subject to
adjustment as provided in the 1999 Omnibus Plan. The maximum number of shares of
common stock that may be awarded in respect of options, restricted stock and
other awards to a single individual in any given year may not exceed 9,375,000,
3,125,000 and 6,250,000, respectively, which amounts are subject to adjustment
as described below. Awards (either as options, restricted stock or other awards)
will be made in a manner consistent with Section 162(m) of the Code. Shares of
common stock acquired upon the exercise or settlement of awards may, in whole or
in part, be authorized but unissued shares or shares that shall have been or may
be reacquired by priceline.com in the open market, in private transactions or
otherwise. If any shares subject to an award are forfeited, cancelled, exchanged
or surrendered or if an award otherwise terminates or expires without a
distribution of shares to the holder of such award, the shares of common stock
with respect to such award will, to the extent of any such forfeiture,
cancellation, exchange, surrender, termination or expiration, again be available
for awards under the 1999 Omnibus Plan.

    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

                                       79
<PAGE>
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 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

                                       80
<PAGE>
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. As of
August 10, 1999, options covering 3,829,505 shares of common stock were
outstanding under the 1999 Omnibus Plan. 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.

    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

                                       81
<PAGE>
of grant of the incentive stock option will result in any difference between the
net sale proceeds and the exercise price being treated as long-term capital gain
or loss to the optionee. If such sale or exchange takes place within two years
after the date of grant of the incentive stock option or within one year from
the date of transfer of the incentive stock option shares to the optionee, such
sale or exchange will generally constitute a "disqualifying disposition" of such
shares that will have the following results: any excess of (a) the lesser of (i)
the fair market value of the shares at the time of exercise of the Incentive
Stock Option and (ii) the amount realized on such disqualifying disposition of
the shares over (b) the option exercise price of such shares, will be ordinary
income to the optionee, subject to applicable withholding taxes, and
priceline.com will be entitled to a tax deduction in the amount of such income.
Any further gain or loss after the date of exercise generally will qualify as
capital gain or loss and will not result in any deduction by priceline.com.

    RESTRICTED STOCK

    A grantee will not recognize any income upon the receipt of restricted stock
unless the holder elects under Section 83(b) of the Code, within thirty days of
such receipt, to recognize ordinary income in an amount equal to the fair market
value of the restricted stock at the time of receipt, less any amount paid for
the shares. If the election is made, the holder will not be allowed a deduction
for amounts subsequently required to be returned to priceline.com. If the
election is not made, the holder will generally recognize ordinary income, on
the date that the restrictions to which the restricted stock are subject are
removed, in an amount equal to the fair market value of such shares on such
date, less any amount paid for the shares. At the time the holder recognizes
ordinary income, priceline.com generally will be entitled to a deduction in the
same amount.

    Generally, upon a sale or other disposition of restricted stock with respect
to which the holder has recognized ordinary income, for example, if a Section
83(b) election was previously made or the restrictions were previously removed,
the holder will recognize capital gain or loss in an amount equal to the
difference between the amount realized on such sale or other disposition and the
holder's basis in such shares.

    OTHER TYPES OF AWARDS

    The grant of any other stock-based award generally will not result in income
for the grantee or in a tax deduction for priceline.com. Upon the settlement of
such an award, the grantee will recognize ordinary income equal to the aggregate
value of the payment received, and priceline.com generally will be entitled to a
tax deduction in the same amount.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

    Section 145 of the Delaware General Corporation Law authorizes a
corporation's board of directors to grant indemnity to directors and officers in
terms sufficiently broad to permit such indemnification under certain
circumstances for liabilities, including reimbursement for expenses incurred,
arising under the Securities Act.

    As permitted by Delaware law, priceline.com's certificate of incorporation
includes a provision that eliminates the personal liability of its directors for
monetary damages for breach of fiduciary duty as a director, except for
liability (1) for any breach of the director's duty of loyalty to priceline.com
or its stockholders; (2) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (3) under Section 174 of
the Delaware General Corporation Law regarding unlawful dividends and stock
purchases; or (4) for any transaction from which the director derived an
improper personal benefit.

    As permitted by Delaware law, 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.

                              CERTAIN TRANSACTIONS

    Priceline.com was founded as a limited liability company in July 1997 and

RELATIONSHIP WITH WALKER DIGITAL

    The priceline.com core buyer driven commerce business model and related
intellectual property rights were initially developed by Walker Digital, a
technology research and development company that was founded and is controlled
by Mr. Walker. In partial consideration for the transfer of such rights and for
the ongoing planning, maintenance and prosecution of the patents related to such
rights, priceline.com issued Walker Digital 6,895,833 shares of common stock.
Priceline.com also granted Walker Digital a perpetual, non-exclusive,
royalty-free right and license to use the intellectual property related to the
priceline.com service for non-commercial internal research and development
purposes. Priceline.com also has the right to purchase at fair market value any
intellectual property that is owned and subsequently acquired, developed or
discovered by Walker Digital that will provide significant value in the use or
commercial exploitation of the priceline.com system.

    Walker Digital currently owns assets and intellectual property related to
two new areas of e-commerce into which priceline.com may expand its "name your
price" business model, one involving consumer-to-consumer sales and the other
involving the sale of retail merchandise. Priceline.com may license its brand
name and "name your price" business model to two new companies formed to develop
these businesses. Walker Digital may contribute assets and intellectual property
to these companies in return for an equity interest in these companies.

    Walker Digital owns the intellectual property rights underlying the
technology associated with priceline.com's adaptive marketing programs. Walker
Digital has licensed to priceline.com the right to use these intellectual
property rights under a perpetual, non-exclusive, royalty-free license
agreement. Walker Digital has pending several United States patent applications
directed to different aspects of the processes and technology supporting
priceline.com's adaptive marketing programs.

    Walker Digital and priceline.com provide each other with a variety of
services. The services provided by priceline.com include various management and
administrative services, for which priceline.com collects fees from Walker
Digital. The services provided by Walker Digital include (1) research and
development assistance; (2) patent planning, maintenance and prosecution; and
(3) intellectual property services, including technical support. Walker Digital
also subleases a portion of its Stamford, Connecticut facilities to
priceline.com on a month-to-month basis. Additionally, priceline.com has
guaranteed Walker Digital's obligations under a lease of 2,500 square feet for
office space in a building in New York City that is used by both companies. The
lease provides for annual rental payments of approximately $170,000 plus
expenses for a term of five years.

    Pursuant to the terms of the indemnification obligations contained in the
Purchase and Intercompany Agreement, Walker Digital has agreed to indemnify
priceline.com for damages, liability and legal expenses incurred in connection
with the Marketel litigation.

    Several of priceline.com's executive officers and other key employees also
are directors, officers, employees or stockholders of Walker Digital and either
own, or hold an option to purchase, equity securities of Walker Digital.


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

*   Represents beneficial ownership of less than one percent.


(a) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission and generally includes voting or
    investment power with respect to securities. Shares of common stock and
    options or warrants that are currently exercisable or exercisable within 60
    days of August 10, 1999 are deemed to be outstanding and to be beneficially
    owned by the person holding such options for the purpose of computing the
    percentage ownership of such person, but are not treated as outstanding for
    the purpose of computing the percentage ownership of any other person. The
    number of shares being sold excludes any shares that may be sold as a result
    of the exercise by the underwriters of their over-allotment option, which if
    exercised, will be allocated pro rata among the selling stockholders.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The following is a summary of certain United States federal income tax
consequences of the purchase, ownership and disposition of the notes and common
stock (into which notes may be converted) by an initial purchaser of the notes.
This summary is based upon existing United States federal income tax law, which
is subject to change, possibly retroactively. This summary does not address all
aspects of United States federal income taxation which may be important to
particular holders in light of their individual investment circumstances, such
as notes held by investors subject to special tax rules (e.g., financial
institutions, insurance companies, regulated investment companies, real estate
investment trusts, broker-dealers, and tax-exempt organizations), persons that
will hold the notes as part of a straddle, hedge, or synthetic security
transaction for United States federal income tax purposes or persons that have a
functional currency other than the United States dollar, all of whom may be
subject to tax rules that differ significantly from those summarized below. In
addition, this summary does not discuss any state or local income or other tax
considerations. This summary assumes that investors will hold their notes and
common stock (into which notes may be converted) as "capital assets" (generally,
property held for investment) for United States federal income tax purposes.
Prospective investors are urged to consult their tax advisors regarding the
United States federal, state, local and foreign income and other tax
consequences of the purchase, ownership and disposition of the notes.

    For purposes of this summary, "U.S. holder" means (i) a citizen or resident
of the United States, (ii) a corporation, partnership or other entity created or
organized in or under the laws of the United States or any political subdivision
thereof, (iii) an estate, the income of which is subject to United States
federal income taxation regardless of its source, or (iv) a trust, the
administration of which is subject to the primary supervision of a court within
the United States and which has one or more United States persons with authority
to control all substantial decisions. "Non-U.S. holder" means a holder that is
not a U.S. holder.

U.S. HOLDERS

TAXATION OF INTEREST

    Interest paid on the notes will be included in the gross income of a U.S.
holder as ordinary income at the time it is received or accrued, in accordance
with such holder's regular method of accounting for U.S. federal income tax
purposes.

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

    Upon the sale, exchange (other than a conversion) or redemption of a note, a
U.S. holder generally will recognize capital gain or loss equal to the
difference between (i) the amount of cash proceeds and the fair market value of
any property received on the sale, exchange or redemption (except to the extent
such amount is attributable to accrued interest not previously included in
income, which will be taxable as ordinary income, or is attributable to accrued
interest that was previously included in income, which amount may be received
without generating further income) and (ii) such holder's adjusted tax basis in
the note. A U.S. holder's adjusted tax basis in a note generally will equal the
cost of the note to such holder. Such capital gain or loss will be long-term
capital gain or loss if the U.S. holder's holding period in the note is more
than one year at the time of sale, exchange or redemption.

CONVERSION OF THE NOTES

    A U.S. holder generally will not recognize any income, gain or loss upon
conversion of a note into common stock except to the extent that any common
stock received is considered attributable to accrued interest not previously
included in income (which will be taxable as ordinary income) or with respect to
cash received in lieu of a fractional share of common stock. A U. S. holder's
tax basis in common stock received on a conversion of a note will be the same as
such holder's adjusted tax basis in the note at the

                                       92
<PAGE>
time of conversion (reduced by any basis allocable to a fractional share
interest). The holding period for common stock received on conversion generally
will include the holding period of the note converted. However, a U.S. holder's
tax basis in shares of common stock received, if any, attributable to accrued
interest generally will equal the amount of such accrued interest included in
income, and the holding period for such shares shall begin on the date following
the date of conversion.

    Cash received in lieu of a fractional share of common stock upon conversion
will be treated as a payment in exchange for the fractional share of common
stock. Accordingly, the receipt of cash in lieu of a fractional share of common
stock generally will result in capital gain or loss (measured by the difference
between the cash received for the fractional share and the holder's adjusted tax
basis in the fractional share).

DIVIDENDS

    Distributions, if any, received in respect of common stock after a
conversion generally will be included in the income of a U.S. holder as ordinary
dividend income to the extent of priceline.com's current or accumulated earnings
and profits. Distributions in excess of priceline.com's current and accumulated
earnings and profits will be treated as a return of capital to the extent of the
U.S. holder's basis in its common stock and thereafter as capital gain.

    U.S. holders of convertible debt instruments such as the notes may, in
certain circumstances, be deemed to have received constructive distributions
where the conversion price of such instruments is adjusted. Adjustments to the
conversion price made pursuant to a bona fide reasonable adjustment formula
which has the effect of preventing the dilution of the interest of the holders
of the debt instruments, however, will generally not be considered to result in
a constructive distribution of stock. Certain of the possible adjustments
provided in the notes (including, without limitation, adjustments in respect of
taxable dividends to shareholders of priceline.com) will not qualify as being
pursuant to a bona fide reasonable adjustment formula. If such adjustments are
made, the U.S. holders of notes will be deemed to have received constructive
distributions taxable as dividends to the extent of priceline.com's current and
accumulated earnings and profits even though they have not received any cash or
property as a result of such adjustments. In certain circumstances the failure
to provide for such an adjustment may result in taxable dividend income to the
U.S. holders of common stock.

SALE, EXCHANGE OR OTHER DISPOSITION OF COMMON STOCK

    Upon the sale, exchange or other disposition of common stock, a U.S. holder
generally will recognize capital gain or loss equal to the difference between
(i) the amount of cash and the fair market value of any property received upon
the sale or exchange and (ii) such U.S. holder's adjusted tax basis in the
common stock. Such capital gain or loss will be long-term capital gain or loss
if the U.S. holder's holding period in common stock is more than one year at the
time of the sale or exchange. A U.S. holder's tax basis and holding period in
common stock received upon conversion of a note are determined as discussed
above under "CONVERSION OF THE NOTES."

NON-U.S. HOLDERS

PAYMENTS OF PRINCIPAL OR INTEREST

    Payments of principal or interest on the notes by priceline.com or any
paying agent to a beneficial owner of a note that is a non-U.S. holder will not
be subject to U.S. withholding tax, provided that, in the case of interest:

    - such non-U.S. holder does not own, actually or constructively, 10% or more
      of the total combined voting power of all classes of stock of
      priceline.com entitled to vote;

                                       93
<PAGE>
    - such non-U.S. holder is not a controlled foreign corporation with respect
      to which priceline.com is a related person for U.S. federal income tax
      purposes;

    - such non-U.S. holder is not a bank which has invested in the notes as an
      extension of credit in the ordinary course of its trade or business; and

    - the certification requirements of section 871(h) or 881(c) of the Internal
      Revenue Code of 1986, as amended (the "Code") are satisfied as described
      below under the heading "OWNER STATEMENT REQUIREMENT."

GAIN REALIZED ON SALE, EXCHANGE OR OTHER DISPOSITION OF NOTES OR COMMON STOCK

    A non-U.S. holder of a note or common stock will not be subject to U.S.
federal income tax on gain realized on the sale, exchange or other disposition
of such note or common stock except in the following circumstances:

    - The gain will be subject to federal income tax if it is effectively
      connected with a trade or business of the non-U.S. holder within the
      United States.

    - The gain will be subject to federal income tax if the non-U.S. holder is
      an individual who holds the note or 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.

    - The gain may be subject to federal income tax pursuant to federal income
      tax laws applicable to certain expatriates.

    - 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. holder held, at any time during the
      five-year period ending on the date of disposition (or, if shorter, the
      non-U.S. holder'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.

DIVIDENDS

    Dividends on common stock after conversion generally will be subject to U.S.
withholding tax at a 30% rate except where an applicable tax treaty provides for
the reduction or elimination of such withholding tax.

OWNER STATEMENT REQUIREMENT

    Sections 871(h) and 881(c) of the Code require that either the beneficial
owner of a note or a securities clearing organization, bank or other financial
institution that holds customers' securities in the ordinary course of its trade
or business (a "Financial Institution") and that holds a note on behalf of such
owner file a statement with priceline.com or its agent to the effect that the
beneficial owner is not a United States person in order to avoid withholding of
United States federal income tax. Under current regulations, this requirement
will be satisfied if priceline.com or its agent receives:

    - a statement (an "Owner's Statement") from the beneficial owner of a note
      in which such owner certifies, under penalties of perjury, that such owner
      is not a United States person and provides such owner's name and address;
      or

                                       94
<PAGE>
    - a statement from the Financial Institution holding the note on behalf of
      the beneficial owner in which the Financial Institution certifies, under
      penalties of perjury, that it has received the Owner's Statement together
      with a copy of the Owner's Statement.

    The beneficial owner must inform priceline.com or its agent (or, in the case
of a statement described in the second bullet point above, the Financial
Institution) within 30 days of any change in information on the Owner's
Statement.

BACKUP WITHHOLDING AND INFORMATION REPORTING

PAYMENTS OF INTEREST

    Current United States federal income tax law provides that in the case of
payments of interest to non-U.S. holders, the 31% backup withholding tax will
not apply to payments made outside the United States by priceline.com or a
paying agent on a note if an Owner's Statement is received or an exemption has
otherwise been established; provided in each case that priceline.com or the
paying agent, as the case may be, does not have actual knowledge that the payee
is a United States person.

DIVIDENDS

    Dividends on common stock paid to non-U.S. holders that are subject to U.S.
withholding tax, as described above, generally will be exempt from U.S. backup
withholding tax but will be subject to certain information reporting
requirements.

PROCEEDS OF A SALE, EXCHANGE OR OTHER DISPOSITION OF NOTES OR COMMON STOCK

    Under current Treasury Regulations, payments of the proceeds of the sale,
exchange or other disposition of a note or common stock to or through a foreign
office of a broker will not be subject to backup withholding but will be subject
to information reporting if the broker is a United States person, a controlled
foreign corporation for United States federal income tax purposes, or a foreign
person 50% or more of whose gross income is from a United States trade or
business for a specified three-year period, unless the broker has in its records
documentary evidence that the beneficial owner is not a United States person and
certain other conditions are met or the non-U.S. holder otherwise establishes an
exemption. Payment of the proceeds of a sale to or through the United States
office of a broker is subject to backup withholding and information reporting
unless the holder certifies its non-United States person status under penalties
of perjury or otherwise establishes an exemption.

NEW FINAL REGULATIONS

    Recently, the Treasury Department has promulgated final regulations (the
"Final Regulations") regarding the withholding and information reporting rules
discussed above. In general, the Final Regulations do not significantly alter
the substantive withholding and information reporting requirements but unify
current certification procedures and forms and clarify reliance standards. Under
the Final Regulations, special rules apply which permit the shifting of primary
responsibility for withholding to certain financial intermediaries acting on
behalf of beneficial owners. The Final Regulations are generally effective for
payments made after December 31, 2000, subject to certain transition rules.

                              DESCRIPTION OF NOTES

    We will issue the notes under an indenture between priceline.com
Incorporated, and Wilmington Trust Company, as trustee. We have filed the form
of the indenture as an exhibit to the registration statement. A copy of the
indenture will also be available at the office of the trustee.

    We have summarized portions of the indenture below. The summary is not
complete. We urge you to read the indenture because it defines your rights as a
holder of the notes. In this section, "priceline.com," "our company," "we" and
"us" each refers only to priceline.com Incorporated and not to any of its
subsidiaries.

GENERAL

    The notes are unsecured general obligations of priceline.com subordinate in
right of payment to Senior Indebtedness, as defined below under "--Subordination
of Notes," of priceline.com and convertible into common stock as described
below. The notes will be limited to $287,500,000 aggregate principal amount,
including $37,500,000 that may be issued upon exercise of the underwriters'
over-allotment option. The notes will mature on August 1, 2006 unless earlier
redeemed by priceline.com or at your option upon a Fundamental Change as defined
below or converted to common stock in accordance with their terms.

    The indenture does not contain any financial covenants or restrictions on
the payment of dividends, the incurrence of Senior Indebtedness or the issuance
or repurchase of securities by priceline.com. The indenture contains no
covenants or other provisions to protect holders of the notes in the event of a
highly leveraged transaction or a change in control, except to the extent
described below under "--Redemption at Your Option."

    The notes will bear interest at the annual rate of   % from August   , 1999.
We will pay interest on February 1 and August 1 of each year, commencing on
February 1, 2000 to holders of record at the close of business on the preceding
January 15 and July 15. Interest may, at our option, be paid either (1) by check
mailed to the address of the person entitled to receive it as it appears in the
note register or (2) by transfer to an account maintained by such person located
in the U.S. if such person has notified us of the details of such account at
least 7 days prior to a scheduled interest payment date; PROVIDED that payments
to The Depository Trust Company, New York, New York will be made by wire
transfer of immediately available funds to the account of The Depository Trust
Company or its nominee. Interest will be computed on the basis of a 360-day year
composed of twelve 30-day months.

    We will maintain an office in the Borough of Manhattan, the City of New York
where we will pay the principal and premium, if any, on the notes and you may
present the notes for conversion, registration of transfer and exchange.

FORM, DENOMINATION AND REGISTRATION

    We will issue the notes in fully registered form, without coupons, in
denominations of $1,000 principal amount and $1,000 multiples.

    GLOBAL NOTE, BOOK-ENTRY FORM.  The notes will be represented by one or more
global notes, which will be deposited with, or on behalf of, The Depository
Trust Company, also known as DTC, and registered in the name of Cede & Co. as
DTC's nominee. A global note may be transferred, in whole or in part, only to
another nominee of DTC or to a successor of DTC or its nominee.

    You may hold your interests in a global note directly through DTC if you are
a participant in DTC, or indirectly through organizations which are participants
in DTC. Transfers between DTC participants will be effected in the ordinary way
in accordance with DTC rules. The laws of some states require that some

                                       96
<PAGE>
investors must take physical delivery of securities in definitive form.
Consequently, the ability to transfer beneficial interests in a global note to
such persons may be limited.

    If you are not a DTC participant, you may beneficially own interests in a
global note held by DTC only through DTC participants, or banks, brokers,
dealers, trust companies and other parties that clear through or maintain a
custodial relationship with a DTC participant, either directly or indirectly. So
long as Cede & Co., as the nominee of DTC, is the registered owner of a global
note, Cede for all purposes will be considered the sole holder of the global
note. Except as provided below, owners of beneficial interests in a global note
will not be entitled to have certificates registered in their names, will not
receive or be entitled to receive physical delivery of certificates in
definitive registered form, and will not be considered the holders of the global
note.

    We will pay interest on and the redemption price of a global note to Cede by
wire transfer of immediately available funds on each interest payment date or
the redemption date, as the case may be. Neither priceline.com, the trustee nor
any paying agent will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in any global note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

    We have been informed by DTC that, with respect to any payment of interest
on, or the redemption price of, any global note, DTC's practice is to credit the
accounts of DTC participants on the payment date with payments in amounts
proportionate to their respective beneficial interests in the principal amount
represented by a global note as shown on the records of DTC, unless DTC has
reason to believe that it will not receive payment on such payment date.
Payments by DTC participants to owners of beneficial interests in the principal
amount represented by a global note held through such participants will be the
responsibility of such participants, as is now the case with securities held for
the accounts of customers registered in "street name."

    Because you cannot hold a physical certificate representing your interest in
a global note and because DTC can only act on behalf of DTC participants, your
ability to pledge such interest to persons or entities that do not participate
in the DTC system, or otherwise take actions in respect of such interest, may be
affected by the absence of a physical certificate representing your interest in
a global note.

    Neither priceline.com, the trustee nor any registrar, paying agent or
conversion agent under the indenture will have any responsibility for the
performance by DTC or its participants or indirect participants of their
obligations under the rules and procedures governing their operations. DTC has
advised priceline.com that it will take any action permitted to be taken by a
holder of notes, including, without limitation, the presentation of notes for
exchange as described below, only at the direction of one or more participants
to whose account with DTC interests in a global note are credited, and only in
respect of the principal amount of the notes represented by a global note as to
which such participant or participants has or have given such direction.

    DTC has advised us that it is a limited purpose trust company organized
under the laws of the State of New York, a member of the Federal Reserve System,
a "clearing corporation" within the meaning of the Uniform Commercial Code and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. DTC was created to hold securities for its participants and to
facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes to the accounts of its
participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers, banks, trust
companies and clearing corporations and may include other organizations such as
the underwriters. Some of DTC's participants or their representatives, together
with other entities, own DTC. Indirect access to the DTC system is available to
others such as banks, brokers, dealers and trust companies that clear through,
or maintain a custodial relationship with, a participant, either directly or
indirectly.

                                       97
<PAGE>
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in global notes among participants, it is under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time.

    CERTIFICATED NOTES.  If DTC or any successor depositary for the global notes
is at any time unwilling or unable to continue as depositary and a successor
depositary is not appointed by us within ninety days, we will issue notes in
definitive registered form in exchange for any global notes. In addition, we may
at any time and in our sole discretion determine not to have the notes
represented by global notes and issue notes in definitive registered form in
exchange for the global notes.

CONVERSION OF NOTES

    You may convert your notes into common stock at any time after the date of
original issuance of the notes through the close of business on the final
maturity date of the notes, unless earlier redeemed by priceline.com or at your
option upon a Fundamental Change. You may convert the principal amount of any
notes, in whole or in part, only in denominations of $1,000 or $1,000 multiples
at the conversion price, subject to adjustment as described below. Except as
described below, no payment or other adjustment will be made for accrued
interest on conversion of any notes or for dividends on any common stock issued
upon conversion of any notes. If any note is converted during the period from,
but excluding, a record date for an interest payment date, to that interest
payment date, then unless that note has been called for redemption on a
redemption date which occurs during such period (in which case we shall not be
required to pay interest on such interest payment with respect to such note),
the notes must be accompanied by funds equal to the interest payable on that
interest payment date on the principal amount so converted; PROVIDED that no
such payment need be made to the extent any overdue interest shall exist at the
time of conversion with respect to such note. We are not required to issue
fractional shares of common stock upon conversion of notes and, instead, will
pay a cash adjustment based upon the market price of common stock on the last
business day prior to the date of conversion. In the case of notes called for
redemption, conversion rights will expire at the close of business on the
business day preceding the day fixed for redemption unless we default in the
payment of the redemption price. You may convert a note which you have elected
to be redeemed upon a Fundamental Change, as defined below, only if you withdraw
your election to redeem in accordance with the terms of the indenture.

    The initial conversion price of $      per share of common stock is subject
to adjustment upon the following events, as set forth in the indenture:

    (1) the issuance of common stock as a dividend or distribution on the common
       stock;

    (2) the issuance to all holders of common stock of rights or warrants to
       purchase common stock at less than the then current market price of the
       common stock;

    (3) subdivisions and combinations of the common stock;

    (4) the distribution to all holders of common stock of capital stock, other
       than common stock, or evidences of indebtedness of priceline.com or of
       assets (including securities, but excluding common stock and those
       rights, warrants, dividends and distributions referred to in (1), (2) or
       (3) above or those paid in cash);

    (5) distributions consisting of cash, excluding:

       (a) any quarterly cash dividend on the common stock to the extent that
           the aggregate cash dividend per share of common stock in any quarter
           does not exceed the greater of:

           -  the amount per share of common stock of the next preceding
              quarterly cash dividend on the common stock to the extent that
              such preceding quarterly dividend did not require an adjustment of
              the conversion price pursuant to this clause (5), adjusted to
              reflect subdivisions or combinations of the common stock, and

                                       98
<PAGE>
           -  3.75% of the average of the last reported sale price of the common
              stock during the ten trading days immediately prior to the date of
              declaration of such dividend, and

       (b) any dividend or distribution in connection with the liquidation,
           dissolution or winding up of priceline.com.

           If an adjustment is required to be made as set forth in this clause
       (5) as a result of a distribution that is a quarterly dividend, such
       adjustment would be based upon the amount by which such distribution
       exceeds the amount of the quarterly cash dividend permitted to be
       excluded pursuant to this clause (5). If an adjustment is required to be
       made as set forth in this clause (5) as a result of a distribution that
       is not a quarterly dividend, such adjustment would be based upon the full
       amount of the distribution;

    (6) payment relating to a tender offer or exchange offer by priceline.com or
       any subsidiary of priceline.com for common stock of priceline.com to the
       extent that the cash and value of any other consideration included in
       such payment per share of common stock exceeds the average of the market
       price per share of common stock on the three trading days immediately
       succeeding the last date on which tenders or exchanges may be made
       pursuant to such tender or exchange offer; and

    (7) payment relating to a tender offer or exchange offer by a person other
       than priceline.com or any subsidiary of priceline.com for common stock of
       priceline.com in which, as of the closing date of the offer, the Board of
       Directors is not recommending rejection of the offer. This adjustment
       will only be made if the tender offer or exchange offer is for an amount
       that increases the offeror's ownership of common stock to more than 25%
       of the total shares of common stock outstanding, and if the cash and
       value of any other consideration included in such payment per share of
       common stock exceeds the average of the market price per share of common
       stock on the three trading days immediately succeeding the last date on
       which tenders or exchanges may be made pursuant to such tender or
       exchange offer. This adjustment will generally not be made, however, if,
       as of the closing of the offer, the offering documents with respect to
       the offer disclose a plan or an intention to cause priceline.com to
       consolidate or merge, or a sell all or substantially all of its assets or
       if the next succeeding paragraph applies.

    In the case of (1) any reclassification of the common stock or (2) a
consolidation, merger or combination involving priceline.com or a sale or
conveyance to another person of the property and assets of priceline.com as an
entirety or substantially as an entirety, in each case as a result of which
holders of common stock shall be entitled to receive stock, other securities,
other property or assets, including cash, with respect to or in exchange for
such common stock, the holders of the notes then outstanding will generally be
entitled after the reclassification, consolidation, merger, combination, sale or
conveyance to convert such notes into the kind and amount of shares of stock,
other securities or other property or assets, including cash, which they would
have owned or been entitled to receive upon the reclassification, consolidation,
merger, combination, sale or conveyance had such notes been converted into
common stock immediately prior to such reclassification, consolidation, merger,
combination, sale or conveyance assuming that a holder of notes would not have
exercised any rights of election as to the stock, other securities or other
property or assets, including cash, receivable in connection with such
transaction.

    The indenture will provide that if we implement a stockholders' rights plan,
the rights plan must provide that, subject to customary exceptions, upon
conversion of the notes you will receive, in addition to the common stock
issuable upon conversion, an appropriate number of rights whether or not such
rights have separated from the common stock at the time of such conversion.

    The indenture will also provide that if rights, warrants or options expire
unexercised, the conversion price shall be readjusted to take into account the
actual number of those warrants, rights or options which were exercised.

                                       99
<PAGE>
    To convert a note, a holder must (1) complete and manually sign the
conversion notice on the back of the note (or complete and manually sign a
facsimile thereof) and deliver such notice to the conversion agent (initially
the trustee) at the office maintained by the conversion agent for such purpose,
(2) surrender the note to the conversion agent, (3) if required, furnish
appropriate endorsements and transfer documents, and (4) if required, pay all
transfer or similar taxes. Pursuant to the indenture, the date on which all of
the foregoing requirements have been satisfied is the conversion date

    If we make a taxable distribution to holders of common stock or in certain
other circumstances requiring an adjustment to the conversion price, the holders
of notes may, in certain circumstances, be deemed to have received a
distribution subject to U.S. income tax as a dividend; in certain other
circumstances, the absence of such an adjustment may result in a taxable
dividend to the holders of common stock. See "Certain United States Federal
Income Tax Considerations" below.

    We may, from time to time and to the extent permitted by law, reduce the
conversion price by any amount for any period of at least 20 days, in which case
we shall give at least 15 days' notice of such reduction, if our Board of
Directors has made a determination that such reduction would be in the best
interests of priceline.com, which determination shall be conclusive. We may, at
our option, make such reductions in the conversion price, in addition to those
set forth above, as our Board of Directors deems advisable to avoid or diminish
any income tax to holders of common stock resulting from any subdivision of
stock, dividend or distribution of stock or securities convertible into or
exchangeable for stock, or rights to acquire stock or securities convertible
into or exchangeable for stock, or from any event treated as such for income tax
purposes. See "Certain United States Federal Income Tax Considerations."

    No adjustment in the conversion price will be required unless such
adjustment would require a change of at least 1% in the conversion price then in
effect; PROVIDED that any adjustment that would otherwise be required to be made
shall be carried forward and taken into account in any subsequent adjustment.
Except as stated above, the conversion price will not be adjusted.

OPTIONAL REDEMPTION BY PRICELINE.COM

    The notes are not entitled to any sinking fund. At any time on or after
August 6, 2002, priceline.com may redeem the notes on at least 30 and not more
than 60 days' notice as a whole or, from time to time, in part at the following
prices, expressed as a percentage of the principal amount, together with accrued
interest to, but excluding, the date fixed for redemption:

</TABLE>

and 100% at and following August 1, 2006, PROVIDED that if the redemption date
is an interest payment date, then the interest payable on such date shall be
paid to the holder of record of the notes on the relevant record date. We will
give notice of any redemption by mail and by publishing the notice in Bloomberg
Business News, DowJones News and Reuters Financial Report in New York City.

    If less than all of the outstanding notes are to be redeemed, the trustee
shall select the notes to be redeemed in principal amounts of $1,000 or $1,000
multiples by lot, PRO RATA or by another method the trustee considers fair and
appropriate. If a portion of a holder's notes is selected for partial redemption
and such holder converts a portion of such notes, the converted portion shall be
deemed to be of the portion selected for redemption.

                                      100
<PAGE>
    We may not give notice of any redemption of notes if a default in payment of
principal, premium or interest on the notes or any other event of default under
the indenture has occurred and is continuing, unless all defaults are cured at
the time of redemption.

REDEMPTION AT YOUR OPTION

    If a "Fundamental Change," as such term is defined below, occurs at any time
prior to August 1, 2006, each holder of notes shall have the right, at the
holder's option, to require priceline.com to redeem any or all of such holder's
notes on the date (the "Repurchase Date") that is 30 days after the date of our
notice of such Fundamental Change. The notes will be redeemable in $1,000
multiples of the principal amount. We shall redeem such notes at a price equal
to 100% of the principal amount to be redeemed plus accrued interest on the
redeemed notes to, but excluding, the Repurchase Date; PROVIDED that, if such
Repurchase Date is an interest payment date, then the interest payable on such
date shall be paid to the holder of record of the notes on the relevant record
date.

    We will mail to all holders of record of the notes a notice of the
occurrence of a Fundamental Change and of the redemption right arising as a
result of the Fundamental Change on or before the tenth day after the occurrence
of such Fundamental Change. We are also required to deliver to the trustee a
copy of such notice. To exercise the redemption right, a holder of notes must
deliver, on or before the close of business on the 30th day after the date of
our notice of a Fundamental Change (the "Fundamental Change Expiration Time"),
written notice of the holder's exercise of such right, together with the notes
to be so redeemed, duly endorsed for transfer, to us or an agent designated by
us for such purpose. Payment for notes surrendered for redemption, and not
withdrawn, prior to the Fundamental Change Expiration Time will be made promptly
following the Repurchase Date.

    The term "Fundamental Change" means the occurrence of any transaction or
event in connection with which all or substantially all of the outstanding
common stock shall be exchanged for, converted into, acquired for or constitute
the right to receive, consideration which is not all or substantially all equity
securities listed, or, upon consummation of or immediately following such
transaction or event, which will be listed, on a U.S. national securities
exchange or approved for quotation on the Nasdaq National Market or any similar
U.S. system of automated dissemination of quotations of securities prices,
whether by means of an exchange offer, liquidation, tender offer, consolidation,
merger, combination, reclassification, recapitalization or otherwise.

    We will comply with the provisions of Rule 13e-4 and any other tender offer
rules under the Securities Exchange Act of 1934 to the extent then applicable in
connection with the redemption rights of the holders of notes in the event of a
Fundamental Change.

    The redemption rights of the holders of notes upon a Fundamental Change
could discourage a potential acquiror of priceline.com. The term "Fundamental
Change" is limited to the specified transactions and may not include other
events that might adversely affect our financial condition, nor would the
requirement that we offer to redeem the notes upon a Fundamental Change
necessarily afford the holders of the notes protection in the event of a highly
leveraged transaction, reorganization, merger or similar transaction involving
priceline.com.

    If a Fundamental Change were to occur, we cannot assure you that we will
have sufficient funds to pay the redemption price for all the notes tendered by
the holders. In addition, any credit agreements or other agreements relating to
other indebtedness to which we are or become a party may contain restrictions or
prohibitions on our ability to redeem notes or may provide that a Fundamental
Change constitutes an event of default under such agreement. If a Fundamental
Change occurs at a time when we are prohibited from redeeming the notes, we
could seek the consent of our then lenders to the redemption of the notes or
could attempt to refinance the borrowings that contain such prohibition. If we
do not obtain such a consent or repay such borrowings, we would remain
prohibited from redeeming the notes. In that case, our failure to redeem
tendered notes would constitute an event of default under the indenture, and may
constitute a

                                      101
<PAGE>
default under the terms of other indebtedness that we may enter into from time
to time. In these circumstances or if the occurrence of a Fundamental Change
itself constitutes an event of default under Senior Indebtedness, the
subordination provisions in the indenture would restrict or prohibit payments to
the holders of notes.

SUBORDINATION OF NOTES

    The payment of the principal of, premium, if any, interest on and all other
amounts payable under the notes is subordinated, to the extent provided in the
indenture, to the prior payment in full of all Senior Indebtedness. This
subordination will not prevent the occurrence of any default or event of default
under the indenture. The notes are also effectively subordinated to all
indebtedness and other liabilities, including trade payables and lease
obligations and all preferred stock, if any, of our subsidiaries.

    Upon any distribution of assets of priceline.com upon:

    (1) any dissolution, winding up, bankruptcy, insolvency, liquidation,
       reorganization, receivership or similar proceeding relating to
       priceline.com or its property,

    (2) an assignment for the benefit of creditors or

    (3) any marshaling of the assets or liabilities of priceline.com,

the holders of Senior Indebtedness will be entitled to receive payment in full,
in cash or other payment satisfactory to the holders of Senior Indebtedness, of
all obligations due in respect of such Senior Indebtedness before the holders of
the notes will be entitled to receive any payment of the principal, premium, if
any, interest, or any other amounts payable in respect of the notes. Until all
obligations with respect to Senior Indebtedness are paid in full in cash or
other payment satisfactory to the holders of Senior Indebtedness, any payment on
the notes to which the holders of notes would be entitled shall be made to the
holders of Senior Indebtedness. By reason of the subordination, if any of the
events described above occur, holders of Senior Indebtedness may receive more,
ratably, and the holders of notes may receive less, ratably, than the other
creditors of priceline.com.

    In the event of any acceleration of the notes because of an event of default
under the indenture, the holders of any Senior Indebtedness then outstanding
would be entitled to payment in full in cash or other payment satisfactory to
the holders of Senior Indebtedness of all obligations in respect of such Senior
Indebtedness before the holders of the notes are entitled to receive any payment
or distribution on the notes. The indenture will require that we promptly notify
holders of Senior Indebtedness if payment of the notes is accelerated because of
an event of default under the indenture. Priceline.com may not pay the notes
until five days after such holders or trustee(s) of Senior Indebtedness receive
notice of such acceleration and, thereafter, may pay the notes only if the
subordination provisions of the Indenture otherwise permit payment at that time.

    We also may not make any payment upon the notes, including upon redemption,
if:

    (1) a default in the payment of the principal of, premium, if any, interest,
       rent or any other obligations in respect of Senior Indebtedness occurs
       and is continuing beyond any applicable period of grace; or

    (2) any other default occurs and is continuing with respect to Senior
       Indebtedness (as defined below) that permits holders of Senior
       Indebtedness as to which the default relates to accelerate its maturity
       and either (1) such default is the subject of judicial proceedings; or
       (2) the trustee receives a notice of such default, also referred to as a
       payment blockage notice, from us or any other person permitted to give
       such notice under the indenture.

    Payments on the notes may and shall be resumed (a) in case of a payment
default, upon the date on which such default is cured or waived or ceases to
exist and (b) in case of a non-payment default, the

                                      102
<PAGE>
earlier of the date on which such nonpayment default is cured or waived or
ceases to exist or 179 days after the date on which the applicable payment
blockage notice is received. Notwithstanding the foregoing, only one payment
blockage notice with respect to the same event of default or any other events of
default existing and known to the person giving such notice at the time of such
notice on the same issue of Senior Indebtedness may be given during any period
of 360 consecutive days unless such event of default or such other events of
default have been cured or waived for a period of not less than 90 consecutive
days. No new payment blockage period may be commenced by the holders of Senior
Indebtedness during any period of 360 consecutive days unless all events of
default which triggered the preceding payment blockage period have been cured or
waived.

    If notwithstanding the foregoing, the trustee or any holder of the notes
receives any payment or distribution of assets of priceline.com of any kind in
contravention of any of the subordination provisions of the indenture, whether
in cash, property, securities or otherwise, including, without limitation, by
way of set-off or otherwise, in respect of the notes before all Senior
Indebtedness is paid in full in cash or other payment satisfactory to holders of
Senior Indebtedness, then such payment or distribution will be held by the
recipient in trust for the benefit of holders of Senior Indebtedness or their
representatives to the extent necessary to make payment in full in cash or
payment satisfactory to the holders of Senior Indebtedness of all Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

    The term "Senior Indebtedness" means the principal of, premium, if any,
interest (including all interest, at or above the rate specified in the
governing instrument, accruing subsequent to the commencement of any bankruptcy,
reorganization or similar proceeding, whether or not a claim for post-petition
interest is allowable as a claim in any such proceeding), rent, liquidated
damages and other obligations payable on or in connection with, and all fees,
costs, expenses and other amounts accrued or due on or in connection with,
Indebtedness (as defined below) of priceline.com, whether outstanding on the
date of the indenture or thereafter created, incurred, assumed, guaranteed or in
effect guaranteed by us, including all deferrals, renewals, extensions,
refinancings or refundings of, or amendments, modifications or supplements to,
the foregoing, unless in the case of any particular Indebtedness the instrument
creating or evidencing the same or the assumption or guarantee thereof expressly
provides that such Indebtedness shall not be senior in right of payment to the
notes or expressly provides that such Indebtedness is PARI PASSU with or junior
to the notes. Notwithstanding the foregoing, the term Senior Indebtedness shall
not include Indebtedness of priceline.com to any of its subsidiaries, a majority
of the voting stock of which is owned, directly or indirectly, by priceline.com.

    The term "Indebtedness" means, with respect to any person, and without
duplication:

    (a) all indebtedness, obligations and other liabilities, contingent or
       otherwise, of such person for borrowed money (including obligations of
       such person in respect of overdrafts, foreign exchange contracts,
       currency exchange or similar agreements, interest rate protection,
       hedging or similar agreements, and any loans or advances from banks,
       whether or not evidenced by notes or similar instruments) or evidenced by
       bonds, debentures, notes or similar instruments (whether or not the
       recourse of the lender is to the whole of the assets of such person or to
       only a portion thereof), other than any account payable or other accrued
       current liability or obligation, in each case incurred in the ordinary
       course of business in connection with the obtaining of materials or
       services,

    (b) all reimbursement obligations and other liabilities, contingent or
       otherwise, of such person with respect to letters of credit, bank
       guarantees or bankers' acceptances,

    (c) all obligations and liabilities, contingent or otherwise, in respect of
       leases of such person required, in conformity with generally accepted
       accounting principles, to be accounted for as capitalized lease
       obligations on the balance sheet of such person and all obligations and
       other liabilities, contingent or otherwise, under any lease or related
       document, including, without

                                      103
<PAGE>
       limitation, the balance deferred and unpaid of any purchase price of any
       property and a purchase agreement, in connection with the lease of real
       property which provides that such person is contractually obligated to
       purchase or cause a third party to purchase the leased property and
       thereby guarantee a minimum residual value of the leased property to the
       lessor and the obligations of such person under such lease or related
       document to purchase or to cause a third party to purchase such leased
       property,

    (d) all obligations of such person, contingent or otherwise, with respect to
       an interest rate or other swap, cap or collar agreement or other similar
       instrument or agreement or foreign currency hedge, exchange, purchase or
       similar instrument or agreement,

    (e) all direct or indirect guaranties or similar agreements by such person
       in respect of, and obligations or liabilities, contingent or otherwise,
       of such person to purchase or otherwise acquire or otherwise assure a
       creditor against loss in respect of, indebtedness, obligations or
       liabilities of another person of the kind described in clauses (a)
       through (d),

    (f) any indebtedness or other obligations described in clauses (a) through
       (d) secured by any mortgage, pledge, lien or other encumbrance existing
       on property which is owned or held by such person, regardless of whether
       the indebtedness or other obligation secured thereby shall have been
       assumed by such person, and

    (g) any and all deferrals, renewals, extensions, refinancings and refundings
       of, or amendments, modifications or supplements to, any indebtedness,
       obligation or liability of the kind described in clauses (a) through (f).

    As of June 30, 1999, we had approximately $-0- million of Indebtedness
outstanding that would have constituted Senior Indebtedness and we had no
subsidiaries. The indenture will not limit the amount of additional
indebtedness, including Senior Indebtedness, which we can create, incur, assume
or guarantee, nor will the indenture limit the amount of indebtedness or other
liabilities that a subsidiary of priceline.com, if any, can create, incur,
assume or guarantee.

    We are obligated to pay reasonable compensation to the trustee and to
indemnify the trustee against certain losses, liabilities or expenses incurred
by it in connection with its duties relating to the notes. The trustee's claims
for such payments will generally be senior to those of the holders of the notes
in respect of all funds collected or held by the trustee.

EVENTS OF DEFAULT; NOTICE AND WAIVER

    An event of default is defined in the indenture as:

    (1) a default in payment of the principal amount of the notes at maturity or
       otherwise;

    (2) default for 30 days in payment of any installment of interest on the
       notes;

    (3) the failure of priceline.com, continuing for 60 days after notice, to
       observe or perform any other covenants in the indenture; or

    (4) the bankruptcy, insolvency or reorganization of priceline.com.

    The indenture provides that the trustee may withhold notice to the holders
of the notes of any default (except in payment of principal or premium, if any,
or interest with respect to the notes) if the trustee considers it in the
interest of the holders of the notes to do so.

    The indenture provides that if an event of default shall have occurred and
be continuing, the trustee or the holders of at least 25% in principal amount of
the notes then outstanding may declare the principal of, premium, if any, and
accrued interest on the notes to be due and payable immediately. In the case of
certain events of bankruptcy or insolvency of priceline.com, the principal of,
premium, if any, and accrued

                                      104
<PAGE>
interest on the notes shall automatically become and be immediately due and
payable. However, if we cure all defaults (except the nonpayment of principal
of, premium, if any, and interest on any of the notes which shall have become
due by acceleration) and certain other conditions are met, with certain
exceptions, such declaration may be canceled and past defaults may be waived by
the holders of a majority of the principal amount of the notes then outstanding.

    The indenture provides that any payment of principal, premium, if any, or
interest that is not made when due (whether or not such payment is permitted to
be made under the subordination provisions described above) will accrue
interest, to the extent legally permissible, at the annual rate otherwise
applicable to the notes from the date on which such payment was required under
the terms of the indenture until the date of payment.

    The holders of a majority in principal amount of the notes then outstanding
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the trustee, subject to certain limitations
specified in the indenture.

    The indenture provides that no holder of the notes may pursue any remedy
under the indenture, except for a default in the payment of principal, premium,
if any (including upon redemption), or interest on the notes, unless such holder
shall have previously given to the trustee written notice of a continuing event
of default, and the holders of at a majority in principal amount of the
outstanding notes shall have made a written request, and offered reasonable
indemnity, to the trustee to pursue the remedy, and the trustee shall not have
received from the holders of a majority in principal amount of the outstanding
notes a direction inconsistent with such request and shall have failed to comply
with such request within 60 days after receipt of such request.

MODIFICATION OF THE INDENTURE

    The indenture contains provisions permitting priceline.com and the trustee,
with the consent of the holders of a majority in principal amount of the notes
at the time outstanding, to modify the indenture or any supplemental indenture
or the rights of the holders of the notes, except that no such modification
shall:

    - extend the fixed maturity of any note,

    - reduce the rate or extend the time for payment of interest on the notes,

    - reduce the principal amount of the notes or premium, if any, on the notes,

    - reduce any amount payable upon redemption of the notes,

    - change the obligation of priceline.com to redeem any note upon the
      happening of any Fundamental Change in a manner adverse to the holders of
      the notes,

    - impair the right of a holder to institute suit for the payment of the
      notes,

    - change the currency in which the notes are payable,

    - impair the right to convert the notes into common stock subject to the
      terms set forth in the indenture, or

    - modify the provisions of the indenture with respect to the subordination
      of the notes in a manner adverse to the holders of the notes in any
      material respect,

without the consent of each holder of a note so affected or reduce the
percentage of notes whose holders are required to consent to any modification of
the indenture or any supplemental indenture, in each case without the consent of
the holders of all of the notes then outstanding. The indenture also provides
for certain modifications of its terms without the consent of the holders of the
notes.

                                      105
<PAGE>
NO RECOURSE AGAINST OTHERS

    The Indenture provides that no director, officer, employee or stockholder of
priceline.com shall have any liability for any obligations of priceline.com
under the notes or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation.

INFORMATION CONCERNING THE TRUSTEE

    We have appointed Wilmington Trust Company, as trustee under the indenture
and paying agent, conversion agent, note registrar and custodian with regard to
the notes. The trustee or its affiliates may from time to time in the future
provide banking and other services to us in the ordinary course of their
business.

    The indenture contains certain limitations on the rights of the trustee,
should it or any of its affiliates become a creditor of priceline.com, to obtain
payment of claims in certain cases or to realize on certain property received in
respect of any such claim as security or otherwise. The trustee and its
affiliates will be permitted to engage in other transactions with priceline.com;
PROVIDED if it or any such affiliate continues to have any conflicting interest
as defined in the indenture and a default occurs with respect to the notes, the
trustee must eliminate such conflict or resign.

RATING OF NOTES

    We believe it is likely that one or more rating agencies may rate the notes.
There can be no assurance as to whether any such agency or agencies will rate
the notes or, if they do, what rating or ratings they will assign to the notes.
If one or more rating agencies assign the notes a rating lower than that
expected by investors, such event could have a material adverse effect on the
market price of the notes and our common stock.

                          DESCRIPTION OF CAPITAL STOCK


    The authorized capital stock of priceline.com consists of 1,000,000,000
shares of common stock, par value $0.008 per share, and 150,000,000 shares of
preferred stock, par value $0.01 per share, of priceline.com. Upon completion of
the concurrent common stock offering, there will be 146,782,296 outstanding
shares of common stock, outstanding options to purchase 26,582,391 shares of
common stock and outstanding warrants to purchase 20,283,573 shares of common
stock.


COMMON STOCK

    Subject to preferences that may apply to shares of preferred stock
outstanding at the time, the holders of outstanding shares of common stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the board of directors may from time to time
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
common stock is not entitled to preemptive rights and is not subject to
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
ratably in the distribution of all of the company's assets remaining available
for distribution after satisfaction of all its liabilities and the payment of
the liquidation preference of any outstanding preferred stock. Each outstanding
share of common stock is, and all shares of common stock to be outstanding upon
completion of this offering will be, fully paid and nonassessable.

PREFERRED STOCK

    The board of directors has the authority, within the limitations and
restrictions stated in the certificate of incorporation, to provide by
resolution for the issuance of shares of preferred stock, in one or more classes
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. See
"Risk Factors--Anti-Takeover Provisions Affecting Us Could Prevent or Delay a
Change of Control."

OPTIONS


    As of August 10, 1999, (1) options to purchase a total of 26,582,391 shares
of common stock were outstanding; and (2) up to 5,729,069 additional shares of
common stock may be subject to options granted in the future under the 1997
Omnibus Plan or the 1999 Omnibus Plan. All of the options contain standard
anti-dilution provisions. See "Management--Priceline.com Incorporated 1997
Omnibus Plan," "--Priceline.com Incorporated 1999 Omnibus Plan" and "--Summary
of Compensation."

    As of August 10, 1999, priceline.com had the following outstanding warrants

various airlines; and (4) 1,000,000 shares of common stock at an exercise price
of $97.41 per share. All of the warrants contain standard anti-dilution

REGISTRATION RIGHTS


    The holders of an aggregate of 144,983,503 shares of common stock or
securities convertible into common stock are entitled to certain registration
rights. After the offering, an aggregate of 142,104,432 shares of common stock
or securities convertible into common stock will continue to be entitled to
registration rights. These rights are provided under the terms of a registration
rights agreement between priceline.com and the holders of the registrable
securities, who include Mr. Braddock, Mr. Walker, Walker Digital, General
Atlantic, Vulcan Ventures Incorporated, other stockholders and several airlines.
This agreement provides demand registration rights to the holders of
substantially all of the registrable securities. In addition, the holders of all
of the registrable securities are entitled under the agreement, subject to
certain limitations, to require priceline.com to include their registrable
securities in future registration statements the company files. Registration of
shares of common stock pursuant to the rights granted in this agreement will
result in such shares becoming freely tradeable without restriction under the
Securities Act of 1933. All registration expenses incurred in connection with
the above registrations will be borne by priceline.com.


    The sale of shares of common stock by the selling stockholders in the
concurrent common stock offering is being made pursuant to the "piggyback"
registration rights contained in the registration rights agreement.
Priceline.com obtained from parties to the registration rights agreement that
hold shares (or presently exercisable warrants to purchase shares) of common
stock available for sale in the concurrent common stock offering a waiver of a
30-day notice period under the agreement and a consent to the assignment of
registration rights by Messrs. Jay Walker and Richard Braddock, each of whom
chose to sell less than his pro rata number of shares in the concurrent common
stock offering. Priceline.com did not obtain such waiver and consent from
certain other parties to the registration rights agreement (comprised of certain
airline participants) because they do not have shares (or presently exercisable
warrants to purchase shares) of common stock available for sale in the
concurrent common stock offering. Priceline.com believes that no damages arise
as a result of the failure to obtain such waiver and consent since such airline
participants do not have shares (or presently exercisable warrants to purchase
shares) of common stock available for sale. Nevertheless, if a disagreement with
such airline participants were to arise, priceline.com can not be certain as to
the effect, if any, that it could have on its relationship with such airline
participants or whether damages or other remedies could be imposed.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for the common stock is ChaseMellon
Shareholder Services, L.L.C.

LISTING

    The common stock is traded on the Nasdaq National Market under the trading
symbol "PCLN."

                        SHARES ELIGIBLE FOR FUTURE SALE

    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 and the concurrent common stock offering,
priceline.com will have outstanding 146,782,296 shares of common stock. Of these
shares, the 5,500,000 shares of common stock sold in the concurrent common stock
offering, the 10,000,000 shares of common stock sold in priceline.com's initial
public offering and the 938,540 shares of common stock eligible to be sold by
employees upon exercise of stock options pursuant to the option exercise program
will be freely tradeable without restriction under the Securities Act unless
purchased by "affiliates" of priceline.com as defined in Rule 144 under the
Securities Act. The shares of common stock issuable upon conversion of the notes
being offered in this offering will be freely tradeable in a similar manner. In
addition, 26,582,391 shares are issuable upon exercise of outstanding options
granted under the 1997 Omnibus Plan and the 1999 Omnibus Plan. Priceline.com has
filed a registration statement on Form S-8 covering the shares of common stock
issuable under such options. As a result, when the options are exercised, the
shares issued will be freely tradeable after September 25, 1999 under the
Securities Act unless purchased by "affiliates" of priceline.com as defined in
Rule 144 under the Securities Act. The balance of priceline.com's outstanding
shares of common stock and the shares of common stock issuable upon exercise of
outstanding warrants will be "restricted securities" under the Securities Act,
subject to restrictions on the timing, manner and volume of sales of such
shares.



    Each of the selling stockholders in the concurrent common stock offering and
Mr. Jay S. Walker, who, after the offerings, will own an aggregate of
147,835,331 shares of common stock, including shares issuable upon exercise of
options and warrants owned by them, have agreed, subject to limited exceptions,

      Omnibus Plan or the 1999 Omnibus Plan or (2) on any appropriate form in
      response to demand registration rights under the registration rights
      agreement.

    The restrictions described in this paragraph do not apply in certain
circumstances, including:

    - the sale of the shares to the underwriters in the concurrent common stock
      offering;

    - the issuance of restricted stock awards under priceline.com's existing

      priceline.com of new lines of business through other entities, PROVIDED
      THAT no such issuance is permitted prior to 180 days after the date of
      this prospectus.


    In addition, holders who will own 3,547,311 shares of common stock after
this offering and options to purchase an additional 4,532,504 shares after this
offering agreed in connection with our initial public offering to similar
restrictions until after September 25, 1999.


    In connection with the option exercise program, holders of options to
purchase 9,676,356 shares of common stock registered on our Form S-8 entered
into lock-up agreements restricting the exercise of their options and sale of
the underlying shares until 180 days after the date of this prospectus, without

additional shares of common stock will be available for sale in the public
market as follows:

Since many of these shares were purchased at prices substantially below current
market prices, we believe a significant number of these shares will be sold when
eligible for resale.

    In general, under Rule 144 as currently in effect, 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 1,400,000 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

                                      110
<PAGE>
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.

    Upon consummation of this offering and the concurrent common stock offering
and subject to the foregoing lock-up agreements, holders of up to 142,153,503
shares of common stock and securities exercisable for shares of common stock
will have certain rights to request the registration of their shares under the
Securities Act. Upon the effectiveness of such registration, all shares covered
by such registration statement would be freely transferable.

    Walker Digital also owns directly approximately 5.2% of our outstanding
common stock. Walker Digital has established an option plan for its officers and
employees that provides for the grant of options to purchase common stock held
by Walker Digital. See "Description of Capital Stock--Registration Rights."

</TABLE>

    The underwriters are offering the notes subject to their acceptance of the
notes from priceline.com and subject to prior sale. The underwriting agreement
provides that the obligation of the underwriters to pay for and accept delivery
of the notes is subject to approval of certain legal matters by its counsel and
to certain other conditions. The underwriters are obligated to take and pay for
all of the notes offered if any are taken, other than the notes covered by the
over-allotment option described below.

    The underwriters propose to offer part of the notes directly to the public
at the public offering price set forth on the cover page of this prospectus and
part to certain dealers at a price which represents a concession not in excess
of       % of the principal amount of the notes. The underwriters may allow, and
such dealers may reallow, a concession not in excess of       % of the principal
amount of the notes to other underwriters or to other dealers. After the initial
offering of the notes, the offering price and other selling terms may from time
to time be varied by the underwriters.

    Priceline.com has granted to the underwriters an option, exercisable within
30 days of the date of the underwriting agreement, to purchase up to an
additional $37,500,000 aggregate principal amount of the notes at the public
offering price set forth on the cover page of this prospectus, less underwriting
discounts and commissions. The underwriters may exercise this option solely for
the purpose of covering over-allotments, if any. To the extent the option is
exercised, each underwriter will become obligated to purchase about the same
percentage of the additional notes as the principal amount listed next to the
underwriter's name in the preceding table bears to the total principal amount of
notes listed next to the names of all underwriters in the preceding table. If
the underwriters' option is exercised in full, the total price to the public
would be $               , the total underwriters' discounts and commissions
would be $       and the total proceeds to priceline.com would be $         .

    The underwriting agreement provides that priceline.com will indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act.

    Priceline.com does not intend to list the notes on any national securities
exchange or seek quotation of the notes on the Nasdaq National Market. The
underwriters have advised priceline.com that they presently intend to make a
market in the notes as permitted by applicable laws and regulations. The
underwriters are not obligated, however, to make a market in the notes and any
such market making may be discontinued at

                                      112
<PAGE>
any time at the sole discretion of the underwriters. Accordingly, no assurance
can be given as to the liquidity of, or trading markets for, the notes.

    Each of priceline.com, the selling stockholders in the concurrent common
stock offering and Mr. Jay S. Walker has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, they
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;

    - as to selling stockholders that are parties to the registration rights
      agreement, 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; or

    - file a registration statement other than, in the case of priceline.com, a
      registration statement (1) on Form S-8 covering shares of common stock
      subject to outstanding options or options to be issued under the 1997
      Omnibus Plan or the 1999 Omnibus Plan or (2) on any appropriate form in
      response to demand registration rights under the registration rights
      agreement.

    The restrictions described in this paragraph do not apply in certain
circumstances, including:

    - the sale of the shares to the underwriters in the concurrent common stock
      offering;

    - the issuance of restricted stock awards under priceline.com's existing
      employee benefit plans or shares of common stock upon the exercise of an
      option or a warrant or the conversion of a security outstanding on the
      date of this prospectus;

    - the grant of options to certain officers, directors, employees or
      consultants provided such options are not exercisable prior to the end of
      the lock-up period;


    - the issuance of warrants (or shares of capital stock upon the exercise of
      such warrants) to suppliers or other entities providing products or
      services to priceline.com in connection with entering into certain supply,
      adaptive marketing or other similar arrangements, provided that the
      recipients of such warrants or shares agree to be bound by the foregoing
      provisions;



    - in the case of each selling stockholder, the sale or other transfers of
      any shares of common stock by certain of the foregoing persons to any
      associate of such selling stockholder, 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; or



    - the grant of exchange rights and the issuance of our common stock on
      exercise of such exchange rights, in connection with the development by
      priceline.com of new lines of business through other entities, PROVIDED
      THAT no such issuance is permitted prior to 180 days after the date of
      this prospectus.

    In order to facilitate the offering of the notes, the underwriters may
engage in transactions that stabilize, maintain or otherwise affect the price of
the notes or the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the notes for their
own account. In addition, to cover over-allotments or stabilize the price of the
notes or the common stock, the underwriters may bid for, and purchase, the notes
or shares of the common stock in the open market. Finally, the underwriting
syndicate may reclaim selling concessions allowed to an underwriter or a dealer
for distributing the notes in the offering, if the syndicate repurchases
previously distributed notes in transactions to cover short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the notes or the common stock above independent
market levels. The underwriters are not required to engage in these activities,
and may discontinue any of these activities at any time.

    Priceline.com has entered into an adaptive marketing agreement with Discover
Financial Services, Inc. Discover Financial Services will pay priceline.com a
fee for qualifying credit applications and qualifying upgrades of existing
Discover credit card accounts. Discover Financial Services and Morgan Stanley &
Co. Incorporated are both wholly owned by Morgan Stanley Dean Witter & Co.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders of
priceline.com Incorporated and Priceline Travel, Inc.

    We have audited the accompanying combined balance sheets of priceline.com
Incorporated and Priceline Travel, Inc. (collectively the Company) as of
December 31, 1997 and 1998 and the related combined statements of operations,
changes in stockholders' equity and cash flows for the period July 18, 1997
(Inception) to December 31, 1997 and the year ended December 31, 1998. These
combined financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these combined
financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the combined financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, such combined financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 1997
and 1998 and the results of their operations and their cash flows for the period
July 18, 1997 to December 31, 1997 and the year ended December 31, 1998 in
conformity with generally accepted accounting principles.

    As discussed in Note 13, the accompanying 1998 financial statements have
been restated.

1. BUSINESS DESCRIPTION

    Priceline.com Incorporated (priceline.com) has pioneered a unique new type
of e-commerce known as a demand collection system that enables consumers to use
the Internet to save money on a wide range of products and services while
enabling sellers to generate incremental revenue. Using a simple and compelling
consumer proposition--name your price, priceline.com collects consumer demand,
in the form of individual customer offers guaranteed by a credit card, for a
particular product or service at a price set by the customer. Priceline.com then
either communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether the customer's
offer can be fulfilled on the basis of the pricing information and rules
established by the sellers. Consumers agree to hold their offers open for a
specified period of time and once fulfilled, offers cannot be canceled. By
requiring consumers to be flexible with respect to brands, sellers and/or
product features, priceline.com enables sellers to generate incremental revenue
without disrupting their existing distribution channels or retail pricing
structures. Priceline.com commenced its service on April 6, 1998 with the sale
of leisure airline tickets. During 1997, the Company had been in the development
stage. Priceline.com's services were expanded to include the sale of new
automobiles, on a test basis, in July 1998, hotel room reservations in October
1998, and home mortgages in January 1999.

    Priceline.com was founded as a limited liability company (LLC) in July 1997
and converted to a corporation in July 1998. All LLC units and options and
warrants to purchase units, were converted in July 1998 to common stock of
priceline.com (Common Stock) and options and warrants to purchase Common Stock.
For presentation purposes all such LLC units, and options and warrants to
purchase units are presented as Common Stock or options and warrants to purchase
Common Stock. Priceline Travel, Inc. (Priceline Travel) holds the travel agency
license used to effect airline ticket sales. Priceline Travel is wholly owned by
the founding stockholder and Vice-Chairman of priceline.com. Priceline.com has a
call option to purchase Priceline Travel for nominal consideration.
Priceline.com and Priceline Travel are entities under common control,
accordingly, the financial statements of the two companies are presented on a
combined basis. Priceline Travel will merge into priceline.com during the first
quarter of 1999. Priceline.com and Priceline Travel are referred to,
collectively, as the Company.

    Walker Digital Corporation (Walker Digital), a research and development
company, developed the priceline.com service and the business model and related
intellectual property rights underlying the priceline.com service, the rights
for which were transferred to the Company on July 18, 1997. Walker Digital had
no operations and no revenues related to the assets transferred to
priceline.com. Walker Digital was founded and is controlled by the founding
stockholder and Vice Chairman of priceline.com. Walker Digital has also been
providing the Company with a variety of services including subleasing office
facilities to the Company on a month to month basis. Charges to the Company for
such services aggregated $19,813 and $706,160 during the period July 18, 1997 to
December 31, 1997 and the year ended December 31, 1998, respectively. Such
amounts are included in general and administrative expense. In addition, the
Company charged Walker Digital $95,874 and $384,831 for the period July 18, 1997
to December 31, 1997 and the year ended December 31, 1998, respectively, for
shared expenses. Such reimbursement has been offset against general and
administrative expenses in the accompanying combined statements of operations.
Several of the Company's executive offers and other key employees are also
officers, employees and/or stockholders of Walker Digital.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    PRINCIPLES OF COMBINATION AND BASIS OF PRESENTATION--The combined financial
statements for all periods presented include the financial statements of
priceline.com and Priceline Travel. The combined financial

             PRICELINE.COM INCORPORATED AND PRICELINE TRAVEL, INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
statements have been prepared in accordance with generally accepted accounting
principles. All significant intercompany transactions have been eliminated.

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

    FAIR VALUE OF FINANCIAL INSTRUMENTS--The Company's financial instruments,
including cash and cash equivalents, restricted bank deposits, accounts
receivable-net and accounts payable, are carried at cost which approximates
their fair value because of the short-term maturity of these financial
instruments. The carrying value of the capital lease obligations and long-term
debt approximates fair value because the interest rates on these obligations are
comparable to the interest rates that could have been obtained at the date of
the balance sheet.

    CASH AND CASH EQUIVALENTS, RESTRICTED BANK DEPOSITS--The Company invests
excess cash primarily in money market accounts, certificates of deposits, and
short-term commercial paper. All highly liquid instruments with an original
maturity of three months or less are considered cash equivalents. Restricted
bank deposits collateralize letters of credit issued in favor of certain
airlines.

    NOTE RECEIVABLE FROM STOCKHOLDER--Represents a note receivable related to
the sale of common stock that was subsequently paid on January 9, 1998.

    PROPERTY AND EQUIPMENT--Property and equipment are stated at historical
cost. Depreciation and amortization of property and equipment is computed on a
straight-line basis, generally over the estimated useful lives of the assets or,
when applicable, the life of the lease, whichever is shorter. Capitalized
software costs represent costs paid to third parties and are amortized on a
straight-line basis over their estimated useful lives. Maintenance and repairs
are charged directly to expense as incurred.

    INTANGIBLE ASSETS--The Company acquired certain patent rights covering the
core buyer-driven commerce system and the method and system for pricing and
selling airline ticket options from a Walker Digital affiliate on July 18, 1997
in exchange for 6,895,833 shares of common stock. Since the transfer was between
entities under common control, it was recorded at the historical cost of the
asset transferred, which was zero.

    IMPAIRMENT OF LONG-LIVED ASSETS--The Company evaluates the recoverability of
its long-lived assets in accordance with Statement of Financial Accounting
Standards (SFAS) No. 121, Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to be Disposed of. SFAS No. 121 requires recognition of
impairment of long-lived assets in the event the net book value of such assets
exceeds the future undiscounted cash flows attributable to such assets.

    REVENUES AND COST OF REVENUES--The manner in which revenues are recognized
differs depending on the product or service sold through the priceline.com
service. With respect to airline ticket or hotel room reservation services,
revenues are generated by transactions with customers who make offers to
purchase airline tickets and hotel rooms supplied by participating sellers. All
offers are guaranteed by a customer credit card. Credit cards are the only form
of payment accepted by priceline.com. Revenues and related costs are recognized
if, and when, the Company accepts the customer's offer and charges the
customer's credit card. Because priceline.com is the merchant of record in these
transactions, revenue for these

                                      F-8

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
services includes the amount billed to the customer, net of certain
transportation taxes and fees. Airline and hotel revenues may be supplemented by
fees that are paid to the Company by third parties in connection with adaptive
marketing programs. With respect to automobile and mortgage services, fees or
other payments payable by the seller and/or the customer are recognized as
revenue. Because priceline.com acts as an intermediary between the customer and
the seller in these transactions, revenue for these products and services is
recorded at the amount of the fee received in connection with the transaction,
and not on the value of the underlying transaction, when the transaction is
completed. Automobile and mortgage services revenues may also include fees from
third parties for adaptive marketing programs.

    Revenues from adaptive marketing programs are earned when customers elect to
increase their offering price, and thus the likelihood of a successful
transaction, at no additional costs, by participating in a sponsor promotion.
Priceline.com earns fee income from the corporate sponsor of each adaptive
marketing program based primarily upon customer participation levels. During
1998, the Company generated approximately $4,037,000 of revenues from adaptive
marketing programs. All of these adaptive marketing revenues resulted from fees
paid to the Company by Capital One Bank in connection with a credit card
promotion--see Note 12.

    Priceline.com expressly permits only credit cards as an acceptable form of
payment from its consumers. Consequently, the Company believes that it does not
have a significant risk of loss with respect to customer transactions. On rare
occasions, the Company provides credit card refunds to individual customers to
satisfy disputes and complaints. The Company accrues for expected credit card
charge-backs and classifies the resulting expense as an addition to the
allowance for doubtful accounts. The Company extends customary payment terms to
corporate customers such as automobile dealers and adaptive marketing sponsors.
The Company did not experience any uncollectible corporate accounts receivable
in 1998.

    Cost of revenues includes product costs and the pro rata amount of the Delta
Warrant earned prior to the December 31, 1998 measurement date based on their
performance through that date--see Note 6.

    SUPPLIER START-UP WARRANT COSTS--Supplier start-up warrant costs includes
the value of warrants issued to secure certain airline alliances and
relationships including the value of the Delta Warrant net of the amount
included in cost of revenues--see Note 6.

    SALES AND MARKETING--Sales and marketing expenses are comprised primarily of
costs of radio and newspaper advertising, costs of the third-party offer-taking
call center, credit card processing fees, provisions for customer credit card
charge-backs and compensation for the Company's sales and marketing personnel.
All sales and marketing costs are expensed as incurred.

    SYSTEMS AND BUSINESS DEVELOPMENT--Systems and business development expenses
are comprised primarily of compensation to the Company's information systems and
product development staff and payments to outside contractors, data
communications and other expenses associated with operating the Company's Web
site, depreciation on computer hardware and licensing fees for computer
software. Such costs are expensed as incurred.

    INTEREST INCOME (EXPENSE), NET--Interest income (expense), net includes
interest income of $523 and $633,294 and interest expense of $835 and $84,920
for the period July 18, 1997 to December 31, 1997 and the year ended December
31, 1998, respectively.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    EQUITY-BASED COMPENSATION--The Company accounts for stock-based employee
compensation arrangements in accordance with provisions of Accounting Principles
Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and
complies with the disclosure provisions of SFAS No. 123, Accounting for
Stock-Based Compensation. Under APB Opinion No. 25, compensation expense is
based on the difference, if any, on the date of grant, between the fair value of
priceline.com's stock and the exercise price.

    The Company accounts for equity instruments issued to non-employees in
accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force
("EITF") Issue No. 96-18, Accounting for Equity Instruments That Are Issued to
Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or
Services. All transactions in which goods or services are the consideration
received for the issuance of equity instruments are accounted for based on the
fair value of the consideration received or the fair value of the equity
instrument issued, whichever is more reliably measurable. The measurement date
of the fair value of the equity instrument issued is the earlier of the date on
which the counterparty's performance is complete or the date on which it is
probable that performance will occur.

    INCOME TAXES--The Company accounts for income taxes in accordance with SFAS
No. 109, Accounting for Income Taxes, which requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
temporary difference between the financial statement and tax basis of assets and
liabilities using presently enacted tax rates in effect. Valuation allowances
are established when necessary to reduce deferred tax assets to the amounts
expected to be realized.

    During the period that priceline.com operated as an LLC, it was treated
substantially as a partnership for tax purposes and, accordingly, the tax effect
of its activities accrued to its members through July 1998.

    NET LOSS PER SHARE--The Company computes net loss per share in accordance
with SFAS No. 128, Earnings Per Share which requires dual presentation of basic
earnings per share ("EPS") and diluted EPS.

    Basic earnings per share is computed using the weighted average number of
common shares outstanding during the period. Diluted earnings per share is
computed using the weighted average number of common shares and potentially
dilutive shares outstanding during the period. Potential common shares consist
of the incremental common shares issuable upon conversion of the Series A and
Series B Convertible Preferred Stock (using the if-converted method) and shares
issuable upon the exercise of stock options and warrants (using the treasury
stock method). At December 31, 1998, Series A and Series B Convertible Preferred
Stock were convertible into 21,610,854 shares and 17,296,874 shares,
respectively, and options and warrants to purchase 42,181,997 shares of Common
Stock were outstanding. Outstanding convertible preferred stock, warrants and
options could potentially dilute basic earnings per share in the future but have
not been included in the computation of diluted net loss per share as the impact
would have been antidilutive for the periods presented.

    BUSINESS RISK--Business risks include the following:

    Competition--The markets for the products and services offered on the
priceline.com service are intensely competitive. The Company competes with both
traditional distribution channels and online services. The Company currently or
potentially competes with a variety of companies with respect to each product or
services offered. The Company potentially faces competition from a number of
large online services that have expertise in developing online commerce and in
facilitating Internet traffic. Many

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
competitors have significant competitive advantages. For example, airlines,
hotels and other suppliers also sell their products and services directly to
consumers and have established Web sites. Internet directories, search engines
and large traditional retailers have significantly greater operating histories,
customer bases, technical expertise, brand recognition and/or online commerce
experience than the Company. In addition, certain competitors may be able to
devote significantly greater resources to furthering their business.

    Dependence on Airline Industry and Certain Carriers--The Company's near
term, and possibly long term, prospects are significantly dependent upon the
sale of leisure airline tickets. Sales of leisure airline tickets and revenues
derived from related adaptive marketing programs represented essentially all of
the Company's revenues for the year ended December 31, 1998. Sales of airline
tickets from the Company's three largest airline suppliers accounted for
approximately 95% of airline ticket revenue for the year ended December 31,
1998. As a result, currently the Company is substantially dependent upon the
continued participation of these three airlines in the priceline.com service in
order to maintain and continue to grow its total airline ticket revenues.
Significantly reducing the Company's dependence on the airlines is likely to
take a long time and there can be no guarantee that the Company will succeed in
reducing that dependence.

    Risks Associated with Brand Development--The Company intends to continue to
pursue an aggressive brand-enhancement strategy, which will include mass market
and multimedia advertising, promotional programs and public relations
activities. To increase awareness of the priceline.com brand and expand it to a
wide range of products and services, the Company will need to continue to spend
significant amounts on advertising and promotions. These expenditures may not
result in a sufficient increase in revenues to cover such advertising and
promotions expenses.

    CONCENTRATION OF CREDIT RISK--Financial instruments which potentially
subject the Company to concentrations of credit risk are principally bank
deposits and accounts receivable. Cash and cash equivalents and restricted bank
deposits are deposited with high credit quality financial institutions. Accounts
receivable typically represent credit card purchases and are derived from the
revenues earned from customers in the U.S. and are denominated in U.S. dollars.
Accounts receivable balances are typically settled through customer credit cards
and, as a result, the majority of accounts receivable are collected upon
processing of credit card transactions. The Company maintains an allowance for
uncollectible accounts based upon the expected collectibility of accounts
receivable. During the year ended December 31, 1998, approximately 11% of
revenues were generated from one vendor participating in an adaptive marketing
program. As of December 31, 1998, amounts due from this vendor represented
approximately 54% of accounts receivable.

    COMPREHENSIVE INCOME--Effective January 1, 1998, the Company adopted SFAS
No. 130, Reporting Comprehensive Income. Under SFAS 130 changes in net assets of
an entity resulting from transactions and other events and circumstances from
non-owner sources are reported in a financial statement for the period in which
they are recognized. Because there were no such changes, adoption of SFAS 130
did not impact the combined financial statements of the Company.

    SEGMENT REPORTING--Effective January 1, 1998, the Company adopted SFAS No.
131, Disclosures About Segments of an Enterprise and Related Information. The
Company operates as a single segment and will evaluate additional segment
disclosure requirements as it expands its operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    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.

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

    On July 18, 1997, priceline.com issued 42,990,211 shares of Common Stock for
the initial contributed services of the founders. No compensation expense was
recognized for the contributed services as priceline.com was in the earliest
phases of development. Such services included conceiving the priceline.com
business model, developing business strategies and operating plans, initiating
contact with airline suppliers and raising capital. There were no employment
agreements related to the services initially contributed and/or the shares
issued in respect of such shares.

    Also, on July 18, 1997, priceline.com issued 6,895,833 shares of Common
Stock to Walker Digital in exchange for the transfer by Walker Digital to
priceline.com all of the rights, title, and interest in certain patents and
patent applications relating to buyer driven commerce.

    In July 1998, priceline.com also issued 8,125,000 shares of Common Stock, to
the Chairman and Chief Executive Officer which resulted in the recognition of a
one time charge of $6,500,000 with respect to these shares. The shares were
issued as compensation for agreeing to accept the position.

    In July 1998, pursuant to an agreement between priceline.com and two
partnerships affiliated with General Atlantic Partners, LP (collectively GAP),
priceline.com sold to GAP a total of 17,288,684 shares of

6. STOCKHOLDERS' EQUITY (CONTINUED)
Series A Convertible Preferred Stock, par value $0.01 per share (the Series A
Preferred Stock) for $20,000,000.

    In December 1998, priceline.com raised net proceeds of approximately
$54,414,550 by completing a private placement of an aggregate of 13,837,500
shares of its Series B Convertible Preferred Stock (the Series B Preferred
Stock) with several investors, including GAP and Vulcan Ventures Incorporated.
Fees of $850,000 have been paid to a company, in which a director of
priceline.com is a director and stockholder, in connection with this
transaction.

    Shares of the Series A and Series B Preferred Stock are automatically
convertible, subject to antidilution adjustment, into an equal number of shares
of Common Stock upon an initial public offering of the Company. The holders of
the Series A and Series B Preferred Stock vote together as a single class with
the holders of Common Stock. If the Company has not consummated an initial
public offering by December 1999, the conversion price of Series B Preferred
Stock will be adjusted to $1.97 per share. Since the Series B Preferred Stock
contained this beneficial conversion feature at the date of issue, the Company
allocated a portion of the proceeds equal to the value of the feature,
$34,650,000, to additional paid-in capital. This amount will be amortized over
one year. Amortization will cease if an initial public offering is completed
within one year and the Series B Preferred Stock convert at $3.20 per share. The
shares of the Series A and Series B Preferred Stock rank senior to the Common
Stock with respect to liquidation and equal to the Common Stock with respect to
dividends.

    In April 1998, priceline.com issued warrants to purchase 125,000 shares of
Common Stock, at a zero exercise price, to a non-employee in exchange for
services rendered to the Company. The estimated fair value of the warrants at
the date of grant of $100,000 was based on the value of the equivalent shares as
of the grant date, that is 125,000 shares at $0.80 per share, and has been
reflected as sales and marketing expense and additional paid-in-capital.

    In April 1998, priceline.com issued warrants to purchase 62,500 shares of
Common Stock at an exercise price of $0.80 per share in conjunction with a
promissory note (see Note 5--Long-Term Debt).

    In August 1998, priceline.com entered into a warrant agreement with Delta
Air Lines (Delta) to purchase up to 18,892,603 shares of Common Stock at an
exercise price of approximately $0.93 per share (Delta Warrant) for agreeing to
participate in the priceline.com service. Vesting was contingent upon
achievement of certain predetermined performance thresholds. However, there was
no penalty for failure to provide ticket inventory to satisfy these performance
thresholds. Accordingly, no expense was recorded when the warrant was issued. On
December 31, 1998, the Company amended its agreement with Delta to eliminate the
vesting contingencies and fix the number of shares subject to the warrant at
18,619,402. The warrants were immediately vested on the date of grant, in that
they are not subject to any forfeiture for any reason. The amended Delta Warrant
will become exercisable at the earlier of seven years or over three years upon
the achievement of certain performance thresholds. The agreement does not
require Delta to make any performance commitments, is non-exclusive and allows
Delta to participate in other programs similar to the priceline.com service.
Accordingly, the Company recognized approximately $58.7 million of expense based
upon the fair value of the warrant on December 31, 1998, of which $3 million is
included in cost of revenues-supplier warrant costs and $55.7 million is
included in expenses-supplier start-up warrant costs in the accompanying
statement of operations.

    On December 31, 1998, priceline.com issued warrants to purchase 937,500
shares of Common Stock at an exercise price of $3.20 per share to three airlines
in recognition of their being among the original

participants in the priceline.com service. Because there are no requirements as
to the nature or length of that participation and the warrants are not subject
to forfeiture for any reason, the Company recognized approximately $2.3 million
of expense based upon the fair value of the warrants at December 31, 1998, which
is included in expenses-supplier start-up warrant costs in the accompanying
statement of operations.

    On January 29, 1999, priceline.com issued warrants to an airline to purchase
1,250,000 shares of Common Stock at an exercise price of $6.40 per share. The
warrants become exercisable as follows, 50% on January 29, 2000 and 50% on
January 29, 2001. The agreement requires the airline to make available to
priceline.com airline ticket inventory on certain specified terms and conditions
for two years. If the airline does not provide the specified airline ticket
inventory, the unexercised warrants are returnable and in addition, there is a
penalty of $1.0 million in the first year and $0.5 million in the second year.
The fair value of the warrant of $3.1 million at the grant date was capitalized
and will be amortized over the two year period during which services will be
provided to the Company.

    The fair value of the airline warrants was based on a third party valuation
using an option pricing model and the following assumptions:

7. STOCK OPTION PLAN

    Priceline.com has adopted the 1997 Omnibus Plan (the Plan), which provides
for grants of options as incentives and rewards to encourage employees,
officers, consultants and directors in the long term success of the Company. The
Plan provides for grants of options to purchase up to 23,875,000 shares at a
purchase price equal to the fair market value on the date of grant. Generally,
the options vest over three years from the date of grant. In accounting for the
Plan, the Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options. When the exercise price of employee
stock options issued under the plan equaled the fair value of the underlying
stock on the date of grant, no compensation expense was recorded. Compensation
expense was recognized for the fair value of the options granted to
non-employees and to the extent fair value of the underlying stock exceeded the
exercise price of employee stock options. Compensation expense, included in
general and administrative, recognized during the year ended December 31, 1998
aggregated $245,063.

    The fair value of each option grant was determined on the date of grant
using the minimum value method. The weighted average fair value of options
granted during 1998 was estimated to be approximately $0.15 on the dates of
grant using the minimum value method and the following assumptions: volatility
of 0%, risk free interest rate of 6.00% and an expected life of 3 years,
respectively. The Plan also provides for the grant of tandem stock appreciation
rights, stand-alone stock appreciation rights, phantom stock and other forms of
equity based incentive awards which do not reduce the number of shares with
respect to which incentive awards may be granted. No such awards were made as of
December 31, 1998.

    In February 1999, priceline.com established the 1999 Omnibus Plan (the 1999
Plan), which provides for grants of options as incentives and rewards to
encourage employees, officers, consultants and directors in the long term
success of the Company. The Plan provides for grants of options to purchase up
to 9,375,000 shares at a purchase price equal to the fair market value on the
date of grant. Generally, the options vest over three years from the date of
grant. The Plan also provides for the grant of tandem stock appreciation rights,
stand-alone stock appreciation rights, phantom stock and other forms of equity
based incentive awards which do not reduce the number of shares with respect to
which incentive awards may be granted.

8. TAXES

    INCOME TAXES--Through July 31, 1998, priceline.com operated as a limited
liability company and income taxes (benefits) accrued to the members.
Accordingly, no income taxes (benefits) were reflected in the accompanying
financial statements as of December 31, 1997 and for the period then ended.
Since converting from an LLC to a corporation in July 1998, the Company has
incurred net operating losses of $22,703,000. This loss will expire if not
utilized by December 31, 2018. As of December 31, 1998 a valuation allowance for
the full amount of the net deferred tax asset of approximately $37,985,023,
resulting from the tax net operating losses and other items was recorded because
of the uncertainty regarding its realization.

    FEDERAL AIR TRANSPORTATION TAX--Currently, a Federal transportation tax is
imposed upon the sale of airline tickets and generally is collected by the
airlines selling the tickets. The tax is based upon a percentage of the cost of
transportation, which was 9% for periods prior to October 1, 1998 and 8%
thereafter. The tax has been calculated based on the amount paid to the airline
for a ticket, rather than the price paid by the customer. There is a possibility
that current law requires computation of the tax based on the price paid by the
customer. Approximately $111,000 in additional taxes relating to the method of
calculating the tax has been accrued as of December 31, 1998.

9. OTHER RELATED PARTY TRANSACTIONS

    The Founder and Vice Chairman of priceline.com also serves as non-executive
Chairman of NewSub Services, Inc. (NewSub), a direct marketing company
co-founded by him. The Company participates in certain adaptive marketing
programs with NewSub. Sales and marketing expense related to these programs
totaled $80,799 for the year ended December 31, 1998. There was no such expense
in 1997.

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

10. COMMITMENTS AND CONTINGENCIES

    LEGAL PROCEEDINGS--On January 6, 1999, priceline.com received notice that a
third party patent applicant and patent attorney, Thomas G. Woolston,
purportedly had filed in December 1998 with the United States

                                      F-17

             PRICELINE.COM INCORPORATED AND PRICELINE TRAVEL, INC.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)
Patent and Trademark Office a request to declare an interference between a
patent application filed by Woolston describing an electronic market for used
and collectible goods and priceline.com's core buyer-driven commerce patent.
Priceline.com has received a copy of a Petition for Interference from Woolston,
the named inventor of at least three United States Patent applications titled
Consignment Nodes, one of which has issued as a patent. Priceline.com currently
is awaiting information from the Patent Office regarding whether it will
initiate an interference proceeding concerning Woolston's patent application and
priceline.com's core buyer-driven commerce patent. An interference is an
administrative proceeding instituted in the Patent Office to determine questions
of patentability and priority of invention between two or more parties claiming
the same patentable invention. There is no statutory period within which the
Patent Office must act on an interference request. If an interference is
declared and proceeds through a final hearing in the Patent Office, a final
judgment is made by the Patent Office as to inventorship. Following such final
judgment, appeals could be made in Federal court. While there can be no
certainty as to time periods, interference proceedings typically take years to
resolve.

    As a threshold to the initiation of an interference proceeding, Woolston
must show that his patent application supports claims that he copied from the
priceline.com core buyer-driven commerce patent. In order to make this showing,
he would have to prove, among other things, that he invented the subject matter
of the priceline.com claims before the inventors of the priceline.com patent. If
the Patent Office were to find that Woolston's patent application supported the
copied priceline.com claims, it would resolve the interference by awarding
inventorship to the party with the earliest proven date of invention. Woolston
recently announced an agreement to license his issued patent and pending patent
applications to the owner of an Internet travel service that, according to such
announcement, commenced on-line operations in the fourth quarter of 1998 and
purports to compete with priceline.com.

    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While Woolston claims to have an earlier
invention date by a period of approximately sixteen months, the final decision
as to priority of invention would be made by the Patent Office after considering
facts provided by each party during the interference proceeding. If an
interference is declared and thereafter resolved in favor of Woolston, such
resolution could result in an award of some or all of the disputed patent claims
to Woolston. If, following such award, Woolston were successful in a patent
infringement action against priceline.com, including prevailing over all
defenses available to priceline.com such as those of non-infringement and
invalidity, this could require priceline.com to obtain licenses from Woolston at
a cost which could significantly adversely affect priceline.com's business. If
Woolston prevailed in both an interference and an infringement action, then
priceline.com could be enjoined from conducting business through the
priceline.com service to the extent covered by the patent claims awarded to
Woolston. In addition, defense of the interference action may be expensive and
may divert management attention away from priceline.com's business.

    On January 19, 1999, Marketel International Inc. (Marketel), a California
corporation, filed a lawsuit against priceline.com and Priceline Travel, among
others. On February 22, 1999, Marketel filed an amended and supplemental
complaint. The amended complaint filed by Marketel alleges causes of action for,
among other things, misappropriation of trade secrets, breach of contract,
conversion, breach of confidential relationship, copyright infringement, fraud,
unfair competition and false advertising, and seeks injunctive relief and
damages in an unspecified amount. In its amended complaint, Marketel alleges,

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

among other things, that the defendants conspired to misappropriate Marketel's
business model, which it describes as a buyer-driven electronic marketplace for
travel services and its appurtenant techniques, market research, forms, plans,
and processes, which allegedly were provided in confidence approximately ten
years ago. The amended complaint also alleges that three former Marketel
employees are the actual sole inventors or co-inventors of a patent which was
issued on August 11, 1998 and which patent has been assigned to priceline.com.
Marketel asks that the patent's inventorship be corrected accordingly.

    Based upon publicly available information, priceline.com believes that
Marketel's fax and fee-based business was launched in 1991 and ceased operations
seven months later. Priceline.com's Internet-based model was independently
developed by Walker Digital and priceline.com, and practiced by the Company
starting in 1998. Based on publicly available information and Marketel's
complaint, priceline.com understands that Marketel operated a fax-based travel
information service which offered consumers, travel agents and/or consolidators
the opportunity to purchase specially printed forms. These forms, when
accompanied by an additional non-refundable fee, allowed prospective ticket
buyers to fax to Marketel credit-card guaranteed bids for airline travel at a
bid price specified by the buyer. The Company believes that Marketel has not
engaged in any regular commercial activities since ceasing operations in 1992.
Based upon publicly available information, Marketel reactivated its active
status as a corporation by satisfying its back-due tax obligations to the State
of California shortly after the filing of its complaint.

    On February 5, and February 10, 1999, the Company filed their answer and
amended answer, respectively, to the amended complaint, in which they denied the
material allegations of liability in the complaint. Priceline.com and all other
defendants strongly dispute the material legal and factual allegations contained
in Marketel's amended complaint and believe that the amended complaint is
without merit. Priceline.com intends to defend vigorously against the action.
Defending the lawsuit may involve significant expense and, due to the inherent
uncertainties of litigation, there can be no certainty as to the ultimate
outcome. Pursuant to the indemnification obligations contained in the Purchase
and Intercompany Services Agreement with Walker Digital, Walker Digital has
agreed to indemnify, defend and hold harmless priceline.com for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.

    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.

11. BENEFIT PLAN

    Priceline.com adopted a defined contribution 401(k) savings plan (the Plan)
during 1998 covering all employees who are at least 21 years old and have
completed 6 months of service. The Plan allows eligible employees to contribute
up to 20% of their eligible earnings, subject to a statutorily prescribed annual
limit. The Company may make matching contributions on a discretionary basis to
the Plan. All participants are fully vested in their contributions and
investment earnings. During the year ended December 31, 1998, the Company did
not make any matching contributions to the Plan.

12. SUBSEQUENT EVENTS

    On March 25, 1999, the Company obtained shareholder approval of a 1.25 for 1
stock split of its common stock and an increase in the authorized shares of its
common stock to 1,000,000,000 shares. In conjunction with the stock split the
par value of the common stock was reduced from $.01 per share to $.008 per
share. All share and per share data have been retroactively adjusted to reflect
the stock split.

    On March 24, 1999, priceline.com exercised its call option to purchase
Priceline Travel for nominal consideration and Priceline Travel was merged into
priceline.com.

    On March 3, 1999, Capital One Bank notified the Company of its termination
of its adaptive marketing program effective May 1, 1999.

13. RESTATEMENT

    Subsequent to the issuance of the Company's combined 1998 financial
statements, the Company's management determined that the calculation of the fair
value of the Delta warrant, other airline warrants and the beneficial conversion
feature on the Series B Preferred Stock should be revised. The fair value of the
Delta warrant and the other airline warrants has been revised to reflect the
change in the volatility assumption from 50% to 132%, eliminate the large block
and lack of marketability discounts, and consider

13. RESTATEMENT (CONTINUED)
the warrant's anti-dilution and exercisability features. As a result, the 1998
combined financial statements have been restated from the amounts previously
reported to recognize an additional $22.0 million of expense based upon the
revised fair value of the warrants at December 31, 1998, of which $3.0 million
is included in the cost of revenues-supplier warrant costs and $19.0 million is
included in expenses-supplier start-up warrant costs. In addition, the value of
the beneficial conversion feature on the Series B Preferred Stock has been
revised to calculate such amount based on 22,500,000 shares. As a result,
additional paid-in capital and accumulated deficit have been restated from
amounts previously reported to recognize an additional $883,424 of accretion of
preferred stock based on the revalued beneficial conversion feature.

    A summary of the significant effects of the restatement is as follows:

                    NOTES TO CONDENSED FINANCIAL STATEMENTS

1. BUSINESS DESCRIPTION

    Priceline.com Incorporated ("priceline.com") has pioneered a 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. Priceline.com collects consumer demand,
in the form of individual customer offers guaranteed by a credit card for a
particular product or service at a price set by the customer. Priceline.com then
either communicates that demand directly to participating sellers or accesses
participating sellers' private databases to determine whether the customer's
offer can be fulfilled on the basis of the pricing information and rules
established by the sellers. Consumers agree to hold their offers open for a
specified period of time and once fulfilled, offers cannot be cancelled. 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 Travel, Inc. ("Priceline Travel") previously held the travel
agency license used to effect airline ticket sales through the priceline.com
service. Priceline Travel was wholly owned by the founding stockholder of
priceline.com and on March 24, 1999, Priceline Travel was merged into
priceline.com for nominal consideration. The accompanying condensed financial
statements include the financial position and results of operations of Priceline
Travel for all periods presented.

2. BASIS OF PRESENTATION

    The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all
adjustments, consisting of normal recurring accruals considered necessary for a
fair presentation, have been included in the accompanying unaudited financial
statements. Operating results for the six months ended June 30, 1999 are not
necessarily indicative of the results that may be expected for the full year
ending December 31, 1999.

3. INITIAL PUBLIC OFFERING OF COMMON STOCK

    On April 1, 1999, priceline.com completed an initial public offering in
which it sold 10,000,000 shares of its common stock at a price of $16.00 per
share, raising $160.0 million in gross proceeds. Offering proceeds to
priceline.com, net of approximately $11.2 million in aggregate underwriters
discounts and commissions and $4.4 million in related expenses, were
approximately $144.4 million. Simultaneous with the effectiveness on March 29,
1999 of priceline.com's Registration Statement on Form S-1, each outstanding
share of priceline.com's Series A and Series B convertible preferred stock was
automatically converted into shares of common stock. As of June 30, 1999,
approximately 142.2 million shares of common stock were outstanding.

4. NET LOSS PER SHARE

    Priceline.com computes net loss per share in accordance with Statement of
Financial Accounting Standards 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

              NOTES TO CONDENSED FINANCIAL STATEMENTS (CONTINUED)

4. NET LOSS PER SHARE (CONTINUED)
of common shares and potentially dilutive shares outstanding during the period.
The effect of the conversion of the Series A and Series B convertible preferred
stock is included in the weighted average number of shares outstanding during
the period that commenced on the conversion date, March 29, 1999. The effect of
the preferred stock conversion for the period prior to March 29, 1999 has not
been included in the computation of diluted net loss per share as the impact
would have been antidilutive for the periods presented. Potential common shares
consist of the incremental common shares issuable upon the exercise of stock
options and warrants. At June 30, 1999, options and warrants to purchase
48,228,959 shares of common stock were outstanding. Outstanding 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.

    Net loss applicable to common stockholders for the six month period ended
June 30, 1999 was $39.8 million including a non-recurring, non-cash charge
associated with the accretion on the Series B convertible preferred stock that
was outstanding during such period of $8.4 million. Based on the weighted
average number of 137.4 million shares of common stock outstanding during the
six month period ended June 30, 1999, the per share basic and diluted net loss
applicable to common stockholders was $0.29.

5. RECENT ACCOUNTING PRONOUNCEMENTS

    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 requires capitalization of
certain costs of computer software developed or obtained for internal use.
Priceline.com adopted this SOP on January 1, 1999 and for the six month period
ended June 30, 1999, priceline.com capitalized approximately $5.7 million of
computer software developed or obtained for internal use. Amortization of such
costs aggregated approximately $149,000 during the six month period ended June
30, 1999.

6. COMMITMENTS AND CONTINGENCIES

    On January 6, 1999, priceline.com received notice that a third party patent
applicant and patent attorney, Thomas G. Woolston, purportedly had filed in
December 1998 with the United States Patent and Trademark Office a request to
declare an "interference" between a patent application filed by Woolston
describing an electronic market for used and collectible goods and
priceline.com's core buyer-driven commerce patent. Priceline.com has received a
copy of a Petition for Interference from Woolston, the named inventor of at
least three United States Patent applications titled "Consignment Nodes," one of
which has issued as a patent. Priceline.com currently is awaiting information
from the Patent Office regarding whether it will initiate an interference
proceeding concerning Woolston's patent application and priceline.com's core
buyer-driven commerce patent.

    Woolston recently announced an agreement to license his issued patent and
pending patent applications to the owner of a competing Internet travel service.

    While the interference process is still at an early stage, priceline.com
believes that it has meritorious defenses to Woolston's claim, which it intends
to pursue vigorously. Among other things, priceline.com believes that the
Woolston patent application does not disclose the inventions covered by the
priceline.com patent claims. However, it is impossible to predict the outcome of
an interference with certainty. While Woolston claims to have an earlier
invention date by a period of approximately sixteen months, the final decision
as to priority of invention would be made by the Patent Office after considering
facts provided by

each party during the interference proceeding. If an interference is declared
and thereafter resolved in favor of Woolston, such resolution could result in an
award of some or all of the disputed patent claims to Woolston. If, following
such award, Woolston were successful in a patent infringement action against
priceline.com, including prevailing over all defenses available to priceline.com
such as those of non-infringement and invalidity, this could require
priceline.com to obtain licenses from Woolston at a cost which could
significantly adversely affect priceline.com's business. If Woolston prevailed
in both an interference and an infringement action, then priceline.com could be
enjoined from conducting business through the priceline.com service to the
extent covered by the patent claims awarded to Woolston. In addition, defense of
the interference action may be expensive and may divert management attention
away from priceline.com's business.

    On January 19, 1999, Marketel International Inc. ("Marketel"), a California
corporation, filed a lawsuit against priceline.com and Priceline Travel, among
others. On February 22, 1999, Marketel filed an amended and supplemental
complaint, and on March 17, 1999, Marketel filed a second amended complaint. The
second amended complaint filed by Marketel alleges causes of action for, among
other things, misappropriation of trade secrets, breach of contract, conversion,
breach of confidential relationship, copyright infringement, fraud, unfair
competition and false advertising, and seeks injunctive relief and damages in an
unspecified amount. In its second amended complaint, Marketel alleges, among
other things, that the defendants conspired to misappropriate Marketel's
business model, which it describes as a buyer-driven electronic marketplace for
travel services and its appurtenant techniques, market research, forms, plans,
and processes, which allegedly were provided in confidence to some of the
defendants approximately ten years ago. The second amended complaint also
alleges that three former Marketel employees are the actual sole inventors or
co-inventors of a patent which was issued on August 11, 1998 and which patent
has been assigned to priceline.com. Marketel asks that the patent's inventorship
be corrected accordingly.

    On February 5, 1999, February 10, 1999 and March 31, 1999, the defendants
filed their answer, amended answer and answer to the second amended complaint,
respectively in which they denied the material allegations of liability in the
complaints. Priceline.com and all other defendants strongly dispute the material
legal and factual allegations contained in Marketel's second amended complaint
and believe that the second amended complaint is without merit. Since May 28,
1999, there has been a discovery stay in effect, which was caused by the
withdrawal of Marketel's counsel. Marketel has retained new counsel, and the
priceline.com now anticipates moving forward with discovery.

    Defending the Marketel litigation may involve significant expense and, due
to the inherent uncertainties of litigation, there can be no certainty as to the
ultimate outcome. Pursuant to the indemnification obligations contained in the
Purchase and Intercompany Services Agreement with Walker Digital, Walker Digital
has agreed to indemnify, defend and hold harmless priceline.com for damages,
liabilities and legal expenses incurred in connection with the Marketel
litigation.

    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. Such claims, even if not meritorious, could result in the expenditure of
significant financial and managerial resources.

7. SUBSEQUENT EVENTS

    COMMON STOCK AND CONVERTIBLE DEBT OFFERINGS.  On July 23, 1999,
priceline.com filed a registration statement covering the sale of up to $287.5
million of convertible subordinated notes (including $37.5 million in respect of
an underwriters' over-allotment option) and up to 6.325 million shares of common
stock (including 825,000 shares in respect of an underwriters' over-allotment
option). The common stock offering is to be comprised of 2.0 million shares of
common stock to be issued and sold by priceline.com and 3.5 million shares to be
sold by certain selling stockholders, plus the sale by the selling stockholders
of any additional shares sold upon exercise of the underwriters' over-allotment
option.


    OPTION EXERCISE PROGRAM.  On July 19, 1999, an option exercise program was
established to enable employees employed as of June 1, 1999 to exercise options
and sell shares through a cashless exercise program administered through a
broker dealer. Priceline.com employees holding 938,540 options that were vested
as of June 1, 1999 were permitted, during the period commencing on July 20, 1999
and ending on July 30, 1999, to exercise a portion of their options that
otherwise were not exercisable until September 26, 1999 (following expiration of
the 180 day initial public offering lock-up period) and to sell the underlying
option shares through the program. Any employee who elected to exercise options
and sell option shares pursuant to the option exercise program was required to
agree to enter into a "lock-up" agreement in a form similar to that signed by
selling stockholders in the secondary common stock offering, which prohibits
additional option exercises or stock sales prior to 180 days from the completion
of the secondary common stock offering.


    CONTINENTAL AIRLINES AGREEMENTS.  Continental Airlines agreed to join the
priceline.com service on July 20, 1999 pursuant to the terms of an Airline
Participation Agreement with priceline.com. Upon exercise of the Airline
Participation Agreement, Priceline.com issued a warrant to Continental for the
purchase of 1 million shares of common stock at an exercise price of $97.41 per
share. The warrant will become exercisable upon the earlier of July 2004 or the
achievement of certain performance thresholds. However the agreement does not
require Continental to make any performance commitments. Priceline.com will
incur a non-cash charge of approximately $90 million during the quarter ending
September 30, 1999, reflecting the fair value of the Continental warrant at the
grant date.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware General Corporation Law authorizes a
corporation's board of directors to grant indemnity to directors and officers in
terms sufficiently broad to permit such indemnification under certain
circumstances for liabilities, including reimbursement for expenses incurred,
arising under the Securities Act of 1933.

    As permitted by Delaware law, Article Seventh of priceline.com's certificate
of incorporation provides that (1) priceline.com is required to indemnify its
directors and officers to the fullest extent permitted by Delaware law, subject
to certain very limited exceptions; (2) priceline.com is permitted to indemnify
its other employees to the extent that it indemnifies its officers and
directors, unless otherwise required by law, its certificate of incorporation,
its by-laws or agreements; (3) priceline.com is required to advance expenses, as
incurred, to its directors and officers in connection with a legal proceeding to
the fullest extent permitted by Delaware law, subject to certain very limited
exceptions; and (4) the rights conferred in the certificate of incorporation are
not exclusive. As permitted by Delaware law, priceline.com's certificate of
incorporation includes a provision that eliminates the personal liability of its
directors for monetary damages for breach of fiduciary duty as a director,
except for liability (1) for any breach of the director's duty of loyalty to
priceline.com or its stockholders; (2) for acts of omissions not in good faith
or that involve intentional misconduct or a knowing violation of law; (3) under
Section 174 of Delaware General Corporation Law regarding payments of dividends,
stock purchases or redemptions which are unlawful; or (4) for any transaction
from which the director derived an improper personal benefit. This provision in
the certificate of incorporation does not eliminate the directors' fiduciary
duty, and in appropriate circumstances equitable remedies such as injunctive or
other forms of non-monetary relief will remain available under Delaware law. In
addition, each director will continue to be subject to liability for breach of
the director's duty of loyalty to priceline.com for acts or omissions not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
unlawful under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.

    As permitted by Delaware law, priceline.com has purchased insurance covering
the company's directors and officers against liability asserted against them in
their capacity as such. Reference is made to the Underwriting Agreement
contained in Exhibit 1.1 hereto, which contains provisions indemnifying officers
and directors of priceline.com against certain liabilities.

ITEM 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.

Dear Sirs and Mesdames:

         Priceline.com Incorporated, a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the several Underwriters named in Schedule II and
Schedule III hereto (the "UNDERWRITERS"), and certain stockholders of the
Company (the "SELLING STOCKHOLDERS") named in Part A of Schedule I hereto
severally propose to sell to the several Underwriters, an aggregate of 5,500,000
shares of the common stock (par value $.008 per share) of the Company (the "FIRM
SHARES"), of which 2,000,000 shares are to be issued and sold by the Company
(the "PRIMARY SHARES") and 3,500,000 shares are to be sold by the Selling
Stockholders, each Selling Stockholder selling the amount set forth opposite
such Selling Stockholder's name in Part A of Schedule I hereto.


                                       1

         It is understood that, subject to the conditions hereinafter stated,
4,400,000 Firm Shares (the "U.S. FIRM SHARES") will be sold to the several U.S.
Underwriters named in Schedule II hereto (the "U.S. UNDERWRITERS") in connection
with the offering and sale of such U.S. Firm Shares in the United States and
Canada to United States and Canadian Persons (as such terms are defined in the
Agreement Between U.S. and International Underwriters of even date herewith),
and 1,100,000 Firm Shares (the "INTERNATIONAL SHARES") will be sold to the
several International Underwriters named in Schedule III hereto (the
"INTERNATIONAL UNDERWRITERS") in connection with the offering and sale of such
International Shares outside the United States and Canada to persons other than
United States and Canadian Persons. Morgan Stanley & Co. Incorporated, Goldman,
Sachs & Co., BancBoston Robertson Stephens Inc., Donaldson, Lufkin & Jenrette
Securities Corporation and Merrill Lynch, Pierce, Fenner & Smith Incorporated
shall act as representatives (the "U.S. REPRESENTATIVES") of the several U.S.
Underwriters, and Morgan Stanley & Co. International Limited, Goldman Sachs
International, BancBoston Robertson Stephens International Limited, Donaldson,
Lufkin & Jenrette International and Merrill Lynch International shall act as
representatives (the "INTERNATIONAL REPRESENTATIVES") of the several
International Underwriters. The U.S. Underwriters and the International
Underwriters are hereinafter collectively referred to as the Underwriters.

         The Selling Stockholders named in Part B of Schedule I hereto also
propose to issue and sell to the several U.S. Underwriters not more than an
additional 825,000 shares of the common stock (par value $.008 per share) of the
Company (the "ADDITIONAL SHARES") if and to the extent that the U.S.
Representatives shall have determined to exercise, on behalf of the U.S.
Underwriters, the right to purchase such shares of common stock granted to the
Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are
hereinafter collectively referred to as the "SHARES." The shares of common stock
(par value $.008 per share) of the Company to be outstanding after giving effect
to the sales contemplated hereby are hereinafter referred to as the "COMMON
STOCK." The 3,500,000 Firm Shares to be sold by the Selling Stockholders and the
Additional Shares are hereinafter collectively referred to as the "SECONDARY
SHARES." The Company and the Selling Stockholders are hereinafter sometimes
collectively referred to as the "SELLERS."

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement relating to the Shares. The registration
statement contains two prospectuses to be used in connection with the offering
and sale of the shares: the U.S. prospectus, to be used in connection with the
offering and sale of Shares in the United States and Canada to United States and
Canadian persons, and the international prospectus, to be used in connection


                                       2
<PAGE>

with the offering and sale of Shares outside of the United States and Canada to
persons other than United States and Canadian Persons. The international
prospectus is identical to the U.S. prospectus except for the outside front
cover page. The registration statement as amended at the time it becomes
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), is hereinafter
referred to as the "REGISTRATION STATEMENT"; the U.S. prospectus and the
international prospectus in the respective forms first used to confirm sales of
Shares are hereinafter collectively referred to as the "PROSPECTUS." If the
Company has filed an abbreviated registration statement to register additional
shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the
"RULE 462 REGISTRATION STATEMENT"), then any reference herein to the term
"REGISTRATION STATEMENT" shall be deemed to include such Rule 462 Registration
Statement.

         1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to and agrees with each of the Underwriters that:

                  (a) The Registration Statement has become effective; no stop
         order suspending the effectiveness of the Registration Statement is in
         effect, and no proceedings for such purpose are pending before or, to
         the knowledge of the Company, threatened by the Commission.

                  (b) (i) The Registration Statement, when it became effective,
         did not contain and, as amended or supplemented, if applicable, will
         not contain any untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, (ii) the Registration Statement and
         the Prospectus comply and, as amended or supplemented, if applicable,
         will comply in all material respects with the Securities Act and the

         the Prospectus does not contain and, as amended or supplemented, if
         applicable, will not contain any untrue statement of a material fact or
         omit to state a material fact necessary to make the statements therein,
         in the light of the circumstances under which they were made, not
         misleading, except that the representations and warranties set forth in
         this paragraph do not apply to statements or omissions in the
         Registration Statement or the Prospectus based upon information
         relating to any Underwriter furnished to the Company in writing by such
         Underwriter through you expressly for use therein.

         and authority to own its property and to conduct its business as
         described in the Prospectus and is duly qualified to transact business
         and is in good standing in each jurisdiction in which the conduct of
         its business or its ownership or leasing of property requires such
         qualification, except to the extent that the failure to be so qualified
         or be in good standing would not have a material adverse effect on the
         Company.

                  (d) The Company has no subsidiaries and does not otherwise own
         or control, directly or indirectly, any corporation, association or
         other entity.

         delivered by the Company.

                  (f) The authorized capital stock of the Company conforms as to

                  (g) The shares of common stock of the Company outstanding
         prior to the issuance of the Primary Shares (including the Secondary
         Shares to be sold by the Selling Stockholders) have been duly
         authorized and are validly issued, fully paid and non-assessable.

                  (h) The Primary Shares to be sold by the Company have been
         duly authorized and, when issued and delivered in accordance with the
         terms of this Agreement, will be validly issued, fully paid and
         non-assessable and the issuance of such Primary Shares will not be
         subject to any preemptive or similar rights.

                  (i) The execution and delivery by the Company of, and the
         performance by the Company of its obligations under, this Agreement
         will not contravene (i) any provision of applicable law; (ii) the
         certificate of incorporation or by-laws of the Company; (iii) except as
         disclosed in the Prospectus, any agreement or other instrument binding
         upon the Company that is material to the Company or (iv) any judgment,
         order or decree of any governmental body, agency or court having
         jurisdiction over the Company, except where, in the case of (i), (iii)
         and (iv), such contravention would not, singly or in the aggregate,
         have a material adverse effect on the Company, and no consent,
         approval, authorization or order of, or qualification with, any
         governmental body or agency is required for the performance by the
         Company of its obligations under this Agreement, except such as have
         been obtained or made or such as may be required by the securities or
         Blue Sky laws of the various states in connection with the offer and
         sale of the Shares or such consents,


                                       4
<PAGE>

         approvals, authorizations, orders or qualifications the failure of the
         Company to obtain would not have a material adverse effect on the
         Company or the offering of Shares contemplated hereunder.

                  (j) There has not occurred any material adverse change, or any
         development involving a prospective material adverse change, in the
         condition, financial or otherwise, or in the earnings, business or
         operations of the Company from that set forth in the Prospectus
         (exclusive of any amendments or supplements thereto subsequent to the
         date of this Agreement).

                  (k) There are no (i) legal or governmental proceedings pending
         or to the Company's knowledge threatened to which the Company is a
         party or to which any of the properties of the Company is subject that
         are required to be described in the Registration Statement or the
         Prospectus and are not so described or (ii) statutes, regulations,
         contracts or other documents that are required to be described in the
         Registration Statement or the Prospectus or to be filed as exhibits to
         the Registration Statement that are not described or filed as required.

                  (l) Each preliminary prospectus filed as part of the
         registration statement as originally filed or as part of any amendment
         thereto, or filed pursuant to Rule 424 under the Securities Act,
         complied when so filed in all material respects with the Securities Act
         and the applicable rules and regulations of the Commission thereunder.

                  (m) The Company is not and, after giving effect to the
         offering and sale of the Primary Shares and the application of the
         proceeds thereof as described in the Prospectus, will not be an
         "investment company" as such term is defined in the Investment Company
         Act of 1940, as amended.

                  (n) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, (i) the
         Company has not incurred any material liability or obligation, direct
         or contingent, nor entered into any material transaction not in the

         material change in the capital stock, short-term debt (other than in
         the ordinary course of business) or long-term debt of the Company,
         except in each case as described in the Prospectus.


                                       5

                  (o) The Company owns no real property and has good and
         marketable title to all personal property owned by it which is material
         to the business of the Company, in each case free and clear of all
         liens, encumbrances and defects except such as are described in the
         Prospectus or such as do not materially affect the value of such
         property and do not materially interfere with the use made or proposed
         to be made of such property by the Company; and any real property and
         buildings held under lease by the Company are held by it under valid,
         subsisting and enforceable leases with such exceptions as are not
         material and do not materially interfere with the use made or proposed
         to be made of such property and buildings by the Company, in each case
         except as described in the Prospectus.

                  (p) Except to the extent described in the Prospectus, the
         Company owns, possesses, or has an irrevocable right to use all
         patents, patent applications, trademarks, trademark applications,
         service marks, service mark applications, trade names, copyrights,
         licenses, inventions, trade secrets, technology and know-how
         (collectively, "INTELLECTUAL PROPERTY RIGHTS") currently employed by it
         in connection with and material to its business as described in the
         Prospectus; other than the claims described in the Prospectus, the
         Company is not aware of any rights of third parties to any such
         Intellectual Property Rights; in connection with the filing of its
         patent applications, the Company conducted reasonable investigations of
         the published literature and patent references relating to the
         inventions claimed in such applications. There are no enforceable
         United States or foreign patents known to the Company which the Company
         believes to be infringed by its present activities or which the Company
         believes would preclude the pursuit of its business as described in the
         Prospectus to any material extent; the Company is not aware of any
         infringement by third parties of any such Intellectual Property Rights
         which would have a material adverse effect on the Company; except as
         described in the Prospectus, there is no pending or, to the Company's
         knowledge, threatened action, suit, proceeding or claim challenging the
         validity or scope of the Company's rights in or to any such
         Intellectual Property Rights; and, except as described in the
         Prospectus, there is no pending or, to the Company's knowledge,
         threatened action, suit, proceeding or claim by others that the Company
         is infringing or otherwise violating intellectual property rights of
         others.

                  (q) The Company possesses all certificates, licenses,
         authorizations and permits (collectively, "GOVERNMENTAL LICENSES")
         issued by the appropriate federal, state or foreign regulatory
         authorities necessary to conduct its business, except such Governmental
         Licenses the


                                       6
<PAGE>

         failure of the Company to possess would not, singly or in the
         aggregate, have a material adverse effect on the Company; the Company
         has not received any notice of proceedings relating to the revocation
         or modification of any Governmental Licenses which, singly or in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, would have a material adverse effect on the Company, except as
         described in the Prospectus.

                  (r) No material labor dispute with the employees of the
         Company exists, except as described in the Prospectus, or, to the
         knowledge of the Company, is imminent.

                  (s) The Company is insured by insurers of recognized financial
         responsibility against such losses and risks and in such amounts as it
         believes are reasonable for the business in which it is engaged and the
         Company believes it will be able to renew or replace its existing
         insurance coverage as and when such coverage expires or to obtain
         similar coverage from financially responsible insurers as may be
         necessary to continue its business at a cost that would not materially
         and adversely affect the Company, except as described in the
         Prospectus.

                  (t) The Company maintains a system of internal accounting
         controls sufficient to provide reasonable assurance that (i)
         transactions are executed in accordance with management's general or
         specific authorizations; (ii) transactions are recorded as necessary to
         permit preparation of financial statements in conformity with generally
         accepted accounting principles and to maintain asset accountability;
         (iii) access to assets is permitted only in accordance with
         management's general or specific authorization; and (iv) the recorded
         accountability for assets is compared with the existing assets at
         reasonable intervals and appropriate action is taken with respect to
         any differences.

                  (u) The Company (i) is in compliance with any and all
         applicable foreign, federal, state and local laws and regulations
         relating to the protection of human health and safety, the environment
         or hazardous or toxic substances or wastes, pollutants or contaminants
         ("ENVIRONMENTAL LAWS"), (ii) has received all permits, licenses or
         other approvals required of it under applicable Environmental Laws to
         conduct its business and (iii) is in compliance with all terms and
         conditions of any such permit, license or approval, except, in each
         case, where such noncompliance with Environmental Laws, failure to
         receive required permits, licenses or other approvals or failure to
         comply with the terms


                                       7
<PAGE>

         and conditions of such permits, licenses or approvals would not have a
         material adverse effect on the Company.

                  (v) Except as described in the Prospectus, there are no
         contracts, agreements or understandings between the Company and any
         person granting such person the right to require the Company to file a
         registration statement under the Securities Act with respect to any
         securities of the Company or to require the Company to include such
         securities with the Shares registered pursuant to the Registration
         Statement.

                  (w) Except as described or referred to in the Registration
         Statement (exclusive of any amendments or supplements thereto
         subsequent to the date of this Agreement) and except for the 10,000,000
         shares of Common Stock sold on April 1, 1999 in the Company's initial
         public offering, the Company has not sold, issued or distributed any
         shares of Common Stock during the six-month period preceding the date
         hereof, including any sales pursuant to Rule 144A under, or Regulations
         D or S of, the Securities Act, other than shares issued pursuant to
         employee benefit plans, qualified stock option plans or other employee
         compensation plans or pursuant to outstanding options, rights or
         warrants.

                  (x) Options issued or to be issued pursuant to any of the
         Company's stock option plans to employees who participated in the
         option exercise program described in the Prospectus are not exercisable
         until 180 days after the date of this Agreement.

                  (y) The Company has reviewed its operations to the extent and
         in the manner described in the Prospectus to evaluate the extent to
         which the business or operations of the Company will be affected by the
         Year 2000 Problem (that is, any significant risk that computer hardware
         or software applications used by the Company will not, in the case of
         dates or time periods occurring after December 31, 1999, function at
         least as effectively as in the case of dates or time periods occurring
         prior to January 1, 2000); as a result of such review, the Company does
         not believe, that there are any issues related to the Company's
         preparedness to address the Year 2000 Problem that are of a character
         required to be described or referred to in the Registration Statement
         or Prospectus which have not been accurately described in the
         Registration Statement or Prospectus.

                  (z) There are no outstanding obligations of the Company to
         repurchase, redeem or otherwise acquire any shares of Common Stock.

         law, or the certificate of incorporation or by-laws of such Selling
         Stockholder (if such Selling Stockholder is a corporation), or any
         agreement or other instrument binding upon such Selling Stockholder or
         any judgment, order or decree of any governmental body, agency or court
         having jurisdiction over such Selling Stockholder, and no consent,
         approval, authorization or order of, or qualification with, any
         governmental body or agency is required for the performance by such
         Selling Stockholder of its obligations under this Agreement or the
         Custody Agreement or Power of Attorney of such Selling Stockholder,
         except such as have been already obtained or as may be required by the
         securities or Blue Sky laws of the various states or foreign countries
         in connection with the offer and sale of the Shares.

                  (c) Such Selling Stockholder has, and on the Closing Date or

         The several obligations of the Underwriters are subject to the

         and prior to the Closing Date:

                           (i) there shall not have occurred any downgrading,

                  potential downgrading or of any review for a possible change
                  that does not indicate the direction of the possible change,
                  in the rating accorded any of the Company's securities by any

                  Prospectus (exclusive of any amendments or supplements thereto
                  subsequent to the date of this Agreement) that, in your
                  judgment, is material and adverse and that makes it, in your

         Underwriters, which will not be unreasonably withheld.

         receipt by the Company of any demand registration request under the
         Registration Rights Agreement so that the Underwriters may exercise

below, the Underwriters will pay all of their costs and expenses, including
fees and disbursements of their counsel, stock transfer taxes payable on
resale of any of the Shares by them and any advertising expenses connected
with any offers they may make.

         The provisions of this Section shall not supersede or otherwise affect
any agreement that the Sellers may otherwise have for the allocation of such
expenses among themselves.

         9. INDEMNITY AND CONTRIBUTION. (a) The Company agrees to indemnify
and hold harmless each Underwriter, each Selling Stockholder and each person,
if any, who controls any Underwriter or Selling Stockholder within the
meaning of either Section 15 of the Securities Act or Section 20 of the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), from and
against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred in
connection with defending or investigating any such action or claim) caused
by any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement or any amendment thereof, any
preliminary prospectus or the Prospectus (as amended or supplemented if the
Company shall have made any amendments or supplements thereto), or caused by
any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein (in the case of
the Prospectus, in light of the circumstances under which they were made) not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement
or omission based upon information relating to any Underwriter furnished to
the Company in writing by such Underwriter through you expressly for use
therein; PROVIDED that the foregoing indemnity agreement with respect to any
preliminary prospectus or the Prospectus shall not inure to the benefit of
any Underwriter from whom the person asserting any such losses, claims,
damages or liabilities purchased Shares, or any person controlling such
Underwriter, if a copy of the Prospectus (as then amended or supplemented, if
the Company shall have made any amendments or supplements) was not sent or
given by or on behalf of such Underwriter to such person, if required by law
so to have been delivered, at or prior to the written confirmation of the
sale of the Shares to such person, and if the Prospectus (as so amended or
supplemented) would have cured the defect giving rise to such loss, claim,
damage or liability.

         (b) Each Selling Stockholder agrees, severally and not jointly, to
indemnify and hold harmless each Underwriter, the Company and each person, if
any, who controls any Underwriter or the Company within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any amendment thereof, any preliminary prospectus or
the Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of the Prospectus, in
light of the circumstances under which they were made) not misleading, but only
with


                                       19
<PAGE>

reference to information relating to such Selling Stockholder furnished to the
Company in writing by or on behalf of such Selling Stockholder expressly for use
in the Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto; PROVIDED that the foregoing indemnity
agreement with respect to any preliminary prospectus or the Prospectus shall not
inure to the benefit of any Underwriter from whom the person asserting any such
losses, claims, damages or liabilities purchased Shares, or any person
controlling such Underwriter, if a copy of the Prospectus (as then amended or
supplemented, if the Company shall have made any amendments or supplements) was
not sent or given by or on behalf of such Underwriter to such person, if
required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Shares to such person, and if the Prospectus (as
so amended or supplemented) would have cured the defect giving rise to such
loss, claim, damage or liability and PROVIDED, FURTHER, that the aggregate
amount of all indemnification reimbursement payable by any Selling Stockholder
pursuant to this Agreement shall in no case exceed the net proceeds to such
Selling Stockholder from the sale of the Secondary Shares.

         (c) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, each Selling Stockholder, the directors of the
Company, the officers of the Company who sign the Registration Statement and
each person, if any, who controls the Company or any Selling Stockholder within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act from and against any and all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred in connection with defending or investigating any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or any amendment thereof,
any preliminary prospectus or the Prospectus (as amended or supplemented if the
Company shall have made any amendments or supplements thereto), or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading (in
the case of the Prospectus, in light of the circumstances under which they were
made), but only with reference to information relating to such Underwriter
furnished to the Company in writing by such Underwriter through you expressly
for use in the Registration Statement, any preliminary prospectus, the
Prospectus or any amendments or supplements thereto.

         (d) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to Section 9(a), 9(b) or 9(c), such person (the "INDEMNIFIED
PARTY") shall promptly notify the person against whom such indemnity may be
sought (the "INDEMNIFYING PARTY") in writing and the indemnifying party, upon


                                       20
<PAGE>

request of the indemnified party, shall retain counsel reasonably satisfactory
to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the reasonable
fees and disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for (i) the fees and expenses of more than one separate firm (in
addition to any local counsel) for all Underwriters and all persons, if any, who
control any Underwriter within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, (ii) the fees and expenses of
more than one separate firm (in addition to any local counsel) for the Company,
its directors, its officers who sign the Registration Statement and each person,
if any, who controls the Company within the meaning of either such Section and
(iii) the fees and expenses of more than one separate firm (in addition to any
local counsel) for all Selling Stockholders and all persons, if any, who control
any Selling Stockholder within the meaning of either such Section, in each case
as applicable, and that all such fees and expenses shall be reimbursed as they
are incurred upon receipt of reasonably detailed invoices thereof. In the case
of any such separate firm for the Underwriters and such control persons of any
Underwriters, such firm shall be designated in writing by Morgan Stanley & Co.
Incorporated. In the case of any such separate firm for the Company, and such
directors, officers and control persons of the Company, such firm shall be
designated in writing by the Company. In the case of any such separate firm for
the Selling Stockholders and such control persons of any Selling Stockholders,
such firm shall be designated in writing by a majority of the persons named as
attorneys-in-fact for the Selling Stockholders under the Powers of Attorney. The
indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement of any pending
or threatened proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of


                                       21
<PAGE>

such indemnified party from all liability on claims that are the subject matter
of such proceeding.

         (e) To the extent the indemnification provided for in Section 9(a),
9(b) or 9(c) is unavailable to an indemnified party or insufficient in respect
of any losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party or parties on the other hand from the offering of the Shares
or (ii) if the allocation provided by clause 9(e)(i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause 9(e)(i) above but also the relative
fault of the indemnifying party or parties on the one hand and of the
indemnified party or parties on the other hand in connection with the statements
or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations. The relative benefits
received by the Sellers on the one hand and the Underwriters on the other hand
in connection with the offering of the Shares shall be deemed to be in the same
respective proportions as the net proceeds from the offering of the Shares
(before deducting expenses) received by each Seller and the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover of the Prospectus, bear to the aggregate Public
Offering Price of the Shares. The relative fault of the Sellers on the one hand
and the Underwriters on the other hand shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Sellers or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Underwriters' respective obligations to
contribute pursuant to this Section 9 are several in proportion to the
respective number of Shares they have purchased hereunder, and not joint.

         (f) The Sellers and the Underwriters agree that it would not be just or
equitable if contribution pursuant to this Section 9 were determined by PRO RATA
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in Section 9(e). The amount paid or payable
by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such


                                       22
<PAGE>

action or claim. Notwithstanding the provisions of this Section 9, no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Shares underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission and no Selling
Stockholder shall be required to contribute any amount in excess of the net
proceeds received by such Selling Stockholder from the offering of the Secondary
Shares. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The remedies
provided for in this Section 9 are not exclusive and shall not limit any rights
or remedies which may otherwise be available to any indemnified party at law or
in equity.

         (g) The indemnity and contribution provisions contained in this Section
9 and the representations, warranties and other statements of the Company and
the Selling Stockholders contained in this Agreement shall remain operative and
in full force and effect regardless of (i) any termination of this Agreement,
(ii) any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, any Selling Stockholder or any person controlling
any Selling Stockholder, or the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Shares.

         10. TERMINATION. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange or the National Association
of Securities Dealers, Inc., (ii) trading of any securities of the Company shall
have been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in your judgment, is material
and adverse and (b) in the case of any of the events specified in clauses
10(a)(i) through 10(a)(iv), such event, singly or together with any other such
event, makes it, in your judgment, impracticable to market the Shares on the
terms and in the manner contemplated in the Prospectus.

         11. EFFECTIVENESS; DEFAULTING UNDERWRITERS. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.


                                       23
<PAGE>

         If, on the Closing Date or the Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase Shares that
it has or they have agreed to purchase hereunder on such date, and the aggregate
number of Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of the Shares to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the number of Firm Shares set forth
opposite their respective names in Schedule II or Schedule III bears to the
aggregate number of Firm Shares set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as you may specify, to
purchase the Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase on such date; PROVIDED that in no event shall the
number of Shares that any Underwriter has agreed to purchase pursuant to this
Agreement be increased pursuant to this Section 11 by an amount in excess of
one-ninth of such number of Shares without the written consent of such
Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail
or refuse to purchase Firm Shares and the aggregate number of Firm Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Firm Shares to be purchased, and arrangements satisfactory to you, the
Company and the Selling Stockholders for the purchase of such Firm Shares are
not made within 36 hours after such default, this Agreement shall terminate
without liability on the part of any non-defaulting Underwriter, the Company or
any Selling Stockholder. In any such case either you or the relevant Sellers
shall have the right to postpone the Closing Date, but in no event for longer
than seven days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected. If, on the Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased, the
non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase Additional Shares or (ii) purchase not less
than the number of Additional Shares that such non-defaulting Underwriters would
have been obligated to purchase in the absence of such default. Any action taken
under this paragraph shall not relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

         If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of any Seller to comply with
the terms or to fulfill any of the conditions of this Agreement, or if for any
reason any Seller shall be unable to perform its obligations under this
Agreement, the Sellers will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses


                                       24
<PAGE>

(including the fees and disbursements of their counsel) reasonably incurred by
such Underwriters in connection with this Agreement or the offering contemplated
hereunder.

         12. COUNTERPARTS. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         13. APPLICABLE LAW. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

         14. HEADINGS. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

Dear Sirs and Mesdames:

         The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") and Morgan Stanley & Co. International Limited ("MSIL")
propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT")
with priceline.com Incorporated, a Delaware corporation (the "COMPANY")
providing for the public offering (the "PUBLIC OFFERING") by the several
underwriters, including Morgan Stanley and MSIL (the "UNDERWRITERS") of shares
(the "SHARES") of the Common Stock (par value $.008 per share) of the Company
(the "COMMON STOCK").
<PAGE>

         To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period commencing
on the date hereof and ending 180 days after the date of the final prospectus
relating to the Public Offering (the "PROSPECTUS"), (1) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock or (2) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
the Common Stock, whether any such transaction described in clause (1) or (2)
above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise. In addition, the undersigned agrees that, without the prior
written consent of Morgan Stanley on behalf of the Underwriters, it will not,
during the period commencing on the date hereof and ending 180 days after the
date of the Prospectus, make any demand for or exercise any right with respect
to, the registration of any shares of Common Stock or any security convertible
into or exercisable or exchangeable for Common Stock.

         The foregoing provisions shall not apply to the sale or other transfer
of shares of Common Stock by the undersigned to any associate (as such term is
defined in Rule 12b-2 of the Securities Exchange Act of 1934) of the
undersigned; PROVIDED THAT, prior to any such sale or other transfer of shares
of Common Stock, any such associated transferee agrees in writing to the
restrictions on transfer set forth herein.

         Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters. In the event that the
Public Offering shall not have been consummated on or before October 31, 1999,
this Lock-Up Agreement shall be of no further force or effect.

                                            Very truly yours,

statement at the time of effectiveness pursuant to Rule 430A of the General
Rules and Regulations under the Act (the "Rules and Regulations") (such
Registration Statement, as so amended, being hereinafter referred to as the
"Registration Statement"); (ii) the final prospectuses dated August 10, 1999
relating to the Shares in the form filed with the Commission pursuant to Rule
424(b) of the Rules and Regulations (the "Prospectuses"); (iii) a specimen
certificate representing the Common Stock; (iv) an executed copy of the
Underwriting Agreement; (v) the Certificate of Incorporation of the Company, as
currently in effect (the "Certificate of Incorporation"); (vi) the Bylaws of the
Company, as currently in effect (the "By-laws");(vii) certain resolutions of the
Board of Directors of the Company and a Pricing Committee of the Board of

Agreement, dated as of December 8, 1998, among the Company, General Atlantic

Continental Airlines, Inc., Northwest Airlines, Inc. and Trans World Airlines,
Inc. (the "Non-Consenting Stock holders") and the Company) consenting to the
assignment of registration rights by certain stockholders and waiving rights to
notice under the Registration Rights Agreement; and (x) an officer's
certificate, dated the date hereof, a copy of which is attached as Exhibit A

representatives of the Company and others, and such other documents,

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 4


certificates and records as we have deemed necessary or appropriate as a basis
for the opinions set forth herein.

                  In our examination, we have assumed the legal capacity of all
natural persons, the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photo static copies and the
authenticity of the originals of such latter documents. In making our
examination of executed documents, we have assumed that the parties thereto,
other than the Company, had the power, corporate or other, to enter into and
perform all obligations thereunder and have also assumed the due authorization
by all requisite action, corporate or other, and execution and delivery by such
parties of such documents and the validity and binding effect thereof on such
parties. As to any facts material to the opinions expressed herein which we did
not independently establish or verify, we have relied upon oral or written
statements and representations of officers and other representatives of the
Company and others. In rendering the opinion set forth in paragraph 4 below, we
have also assumed, with your consent, that the certificates representing the
Primary Shares will be manually signed by one of the authorized officers of the
Transfer Agent and Registrar for the Common Stock and registered by such
Transfer Agent and Registrar and will conform to the specimen thereof examined
by us.

                  As used herein, (i) the term "Applicable Laws" means those
laws of the State of New York, the State of Delaware and the United States of
America that, in each case, in our experience, are normally applicable to
transactions of the type contemplated by the Underwriting Agreement (except for
United States, state and foreign securities or Blue Sky laws, anti-fraud laws
and the rules and regulations of the National Association of Securities Dealers,
Inc.) but without our having made any special

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 5


investigation regarding any other laws; (ii) the term "Governmental Authorities"
means any federal, New York or Delaware executive, legislative, judicial,
administrative or regulatory body; (iii) the term "Applicable Orders" means
those judgments, orders or decrees of any Governmental Authorities specifically
identified to us by the Company to be applicable to the Company, as identified
on Schedule II hereto and (iv) the term "Governmental Approval" means any
consent, approval, license, authorization or validation of, or filing,
qualification or registration with, any Governmental Authority required to be
made or obtained by the Company pursuant to Applicable Laws, other than any
consent, approval, license, authorization, validation, filing, qualification or
registration which may have become applicable as a result of your involvement in
the transactions contemplated by the Underwriting Agreement or because of your
legal or regulatory status or because of any other facts specifically
pertaining to you.

                  Our opinion set forth in paragraph 1 below as to the existence
and good standing of the Company under the laws of the State of Delaware is
based solely on our review of a certificate to such effect from the Secretary of
State of the State of Delaware.

                  Members of our firm are admitted to the bar in the State of
New York and the State of Delaware and we do not express any opinion as to the
laws of any other jurisdiction other than the laws of the United States of
America to the extent referred to specifically herein.

                  Based upon and subject to the limitations, qualifications,
exceptions and assumptions set forth herein, we are of the opinion that:

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 6


                  1. The Company is a corporation validly existing and in good
standing under the laws of the State of Delaware.

                  2. The Company has the corporate power and corporate authority
to own, lease and operate its proper ties and to conduct its business as
described in the Registration Statement.

                  3. The authorized capital stock of the Company conforms as to
legal matters to the description thereof contained in each Prospectus.

                  4. The Primary Shares have been duly authorized by the
Company and, when delivered to and paid for by the Underwriters in accordance
with the terms of the Underwriting Agreement, will be validly issued, fully paid
and non-assessable shares of Common Stock; and the issuance of the Primary
Shares will not be subject to any preemptive or similar rights arising under the
Certificate of Incorporation or the By-laws or the General Corporation Law of
the State of Delaware, in each case as currently in effect.

                  5. The Underwriting Agreement has been duly authorized,
executed and delivered by the Company.

                  6. The execution and delivery of the Underwriting Agreement by
the Company and the consummation by the Company of the transactions
contemplated thereby will not contravene (i) the Certificate of Incorporation or
the By-laws; (ii) any Applicable Law; (iii) except to the extent disclosed in
the Prospectuses, any Applicable Contract; (iv) any Applicable Order; or (v) the
Act, the Rules and Regulations, the Securities Exchange Act of 1934, as amended
(the "Exchange Act") or the rules and regulations thereunder, PROVIDED, HOWEVER,
that we express no opinion in this paragraph 6 with regard to the anti-fraud
provisions of

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 7


the Act, the Rules and Regulations, the Exchange Act or the rules and
regulations thereunder or the information contained in, the accuracy,
completeness or correctness of, or the adequacy of the disclosure contained in,
each Prospectus or the Registration Statement or the responsiveness thereof to
the requirements of the Act and the Rules and Regulations, which matters are
addressed in paragraph 10 below and the second paragraph following paragraph 11
below.

                  7. No Governmental Approval, or consent, filing, registration
or approval of or with the Commission, is required to be made or obtained by
the Company for the execution and delivery by the Company of the Underwriting
Agreement or the issuance and sale of the Primary Shares by the Company pursuant
to the Underwriting Agreement, except such as have been obtained or made.

                  8. The statements set forth in each Prospectus under the
caption "Description of Capital Stock" and in Item 14 of the Registration
Statement, insofar as such statements constitute summaries of legal matters or
certain provisions of the documents referred to therein, fairly summarize the
matters referred to therein in all material respects.

                  9. Although the discussion set forth in each Prospectus under
the caption "Certain United States Federal Tax Consequences to Non-U.S.
Investors" does not purport to discuss all possible United States federal income
tax consequences of the purchase, ownership, and disposition of Shares, such
discussion constitutes, in all material respects, a fair summary of the United
States federal income tax consequences to Non-U.S. Investors of the purchase,
ownership and disposition of Shares under current law.

                  10. The Registration Statement, at the time it became
effective, and each Prospectus, as of its date,

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 8


appeared on their face to be appropriately responsive in all material respects
to the requirements of the Act and the Rules and Regulations, except that, in
each case, we express no opinion as to the financial statements, schedules and
other financial and statistical data included therein or excluded therefrom or
the exhibits thereto, and, except to the extent expressly stated in paragraphs 8
and 9 above, we do not assume any responsibility for the accuracy, completeness
or fairness of the statements contained in the Registration Statement or either
Prospectus.

                  11. The Company is not and, upon the consummation of the
transactions contemplated by the Underwriting Agreement, will not be, an
investment company under the Investment Company Act of 1940, as amended.

                  We have been orally advised by the Commission that the
Registration Statement was declared effective under the Act at ____ p.m. on
August 10, 1999. We have been orally advised by the Commission that no stop
order suspending the effectiveness of the Registration Statement has been
issued and, to the best of our knowledge, no proceedings for that purpose have
been instituted or are pending or threatened by the Commission.

                  In addition, we have participated in conferences with officers
and other representatives of the Company, certain Selling Stockholders, counsel
for the Selling Stockholders, representatives of the independent accountants of
the Company, your counsel and you at which the contents of the Registration
Statement and the Prospectuses and related matters were discussed and, although
we are not passing upon, and do not assume any responsibility for, the accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Prospectuses and have made no independent check or
verification thereof (except to the extent expressly stated in paragraphs 8 and
9

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 9


above), on the basis of the foregoing, no facts have come to our attention that
have led us to believe that the Registration Statement, at the time it became
effective, contained an untrue statement of a material fact or omitted to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading, or that either Prospectus, as of its date and
as of the date hereof, contained or contains an untrue statement of a material
fact or omitted or omits to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that we express no opinion or belief with respect to the
financial statements, schedules and other financial and statistical data
included therein or excluded therefrom or the exhibits to the Registration
Statement.

                  This opinion is furnished to you solely for your benefit in
connection with the closing under the Underwriting Agreement occurring today and
is not to be used, circulated, quoted or otherwise referred to for any other
purpose or relied upon by any other person without our express written
permission.


                                                  Very truly yours,

Ladies and Gentlemen:

         I am Senior Vice President, General Counsel and Secretary of
priceline.com Incorporated, a Delaware corporation (the "Company"), and have
acted as general counsel to the Company in connection with the Underwriting
Agreement, dated August 10, 1999 (the "Underwriting Agreement"), among the
Company, certain stockholders of the Company named therein (the "Selling
Stockholders"), Morgan Stanley & Co. Incorporated, Goldman Sachs & Co., Allen &
Company Incorporated, BancBoston Robertson Stephens Inc., Donaldson, Lufkin &
Jenrette Securities Corporation and Merrill Lynch, Pierce, Fenner & Smith
Incorporated as representatives of the several U.S. Underwriters named therein
(the "U.S. Underwriters"), and Morgan Stanley & Co. International Limited,
Goldman Sachs International, Allen & Company Incorporated, BancBoston Robertson
Stephens International Inc., Donaldson, Lufkin & Jenrette International and
Merrill Lynch International as representatives of the several International
Under writers named therein (the "International Underwriters" and together with
the U.S. Underwriters, the "Underwriters"), relating to the sale to the several
Underwriters by the Company of 2,000,000 shares (the "Primary Shares") of the
Company's common stock, par value $.008 per share ("Common Stock"), and by the
Selling Stockholders of 3,500,000 shares of Common Stock (the "Secondary Shares"
and, together with the Primary Shares, the "Shares").

         This opinion is being furnished pursuant to Section 6(d) of the
Underwriting Agreement.

         In connection with this opinion, I have examined originals or copies,
certified or otherwise identified to my satisfaction, of (i) the Registration
Statement on Form S-1 (File No. 333-83513) relating to the Shares, filed with
the Securities and Exchange Commission (the "Commission") on July 23, 1999 under
the Securities Act of 1933, as amended, (the "Act"), Amendment No. 1 thereto
filed with the Commission on August 2, 1999 and Amendment No. 2 thereto filed
with the Commission on August [9][10], 1999, including information deemed to be
a part of the registration statement at the time of effectiveness pursuant to
Rule 430A of


                                       2
<PAGE>

the General Rules and Regulations under the Act (the "Rules and Regulations")
(such Registration Statement, as so amended, being here inafter referred to as
the "Registration Statement"); (ii) the final prospectuses dated August 10, 1999
relating to the Shares in the form filed with the Commission pursuant to Rule
424(b) of the Rules and Regulations (the "Prospectuses"); (iii) a specimen
certificate representing the Common Stock; (iv) an executed copy of the Under
writing Agreement; (v) the Certificate of Incorporation of the Company, as
currently in effect (the "Certificate of Incorporation"); (vi) the By-laws of
the Company, as currently in effect (the "By-laws");(vii) certain resolutions
of the Board of Directors of the Company and a Pricing Committee of the Board of
Directors of the Company; (viii) a certificate of the Chief Executive Officer
and Chief Financial Officer of the Company as to the factual matters covered
thereby, a copy of which is attached hereto (the "Officers' Certificate"); (ix)
the agreements included as exhibits to the Registration Statement (the "Material
Contracts"); and (x) certain documents purporting to assign the rights to United
States patents No. 5,794,207 and No. 5,797,127 (collectively, the "Patents") to
the Company. I have also examined originals or copies, certified or otherwise
identified to my satisfaction, of such records of the Company and such
agreements, certificates of public officials, certificates of officers or other
representatives of the Company and others, and such other documents,
certificates and records as I have deemed necessary or appropriate as a basis
for the opinions set forth herein.

         In my examination, I have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents. In making my examination
of executed documents, I have assumed that the parties thereto, other than the
Company, had the power, corporate or other, to enter into and perform all
obligations thereunder and I have also assumed the due authorization by all
requisite action, corporate or other, and execution and delivery by such


                                       3
<PAGE>

parties of such documents and the validity and binding effect thereof on such
parties.

         As used herein, (i) the term "Applicable Laws" means the General
Corporation Law of the State of Delaware and those laws of the State of
Connecticut and the United States of America that, in each instance, are
normally applicable to transactions of the type contemplated by the Underwriting
Agreement (except for United States, state and foreign securities or Blue Sky
laws, anti-fraud laws, laws affecting creditors rights generally and the rules
and regulations of the National Association of Securities Dealers, Inc.) but
without my having made any investigation regarding any other laws; (ii) the term
"Governmental Authorities" means any federal or Connecticut executive,
legislative, administrative or regulatory body and the Secretary of State of the
State of Delaware and (iii) the term "Governmental Approval" means any consent,
approval, license, authorization or validation of, or filing, qualification or
registration with, any Governmental Authority required to be obtained or made by
the Company pursuant to Applicable Laws, other than any consent, approval,
license, authorization, validation, filing, qualification or registration which
may have become applicable as a result of your involvement in the transactions
contemplated by the Underwriting Agreement or because of your legal or
regulatory status or because of any other facts specifically pertaining to you.

         In providing the opinions set forth in paragraphs 2, 5, 6, 8, 9 and 10
below, I have made no investigation or search of public docket records of any
court, governmental or administrative agency or body, or of any filings,
applications or registrations with the United States Patent and Trademark Office
or the United States Copy right Office.

         For the purposes of the opinions set forth in paragraphs 2, 5, 6, 8, 9
and 10 below, the expressions "to my knowledge" and "I have no knowledge" are
each limited to those matters brought to my attention after reasonable inquiry
of officers of the Company.


                                       4
<PAGE>

         For the purposes of the opinion set forth in paragraph 10 below, the
term "Liens" means all presently asserted liens or other encumbrances.

         Insofar as the opinion in paragraph 1 below relates to the laws of the
States of California, Ohio, New Jersey or New York [ANY OTHERS?], I have relied
solely on certificates of due qualification and good standing from the
Secretary of State of each such state.

         I am the Senior Vice President, General Counsel and Secretary of the
Company, and have held such position since September 1998. I am admitted to the
bar in the State of Connecticut and, except to the extent set forth in the
preceding paragraph, I do not express any opinion as to the laws of any other
jurisdiction other than the General Corporation Law of the State of Delaware and
the laws of the United States of America to the extent referred to specifically
herein. I am not registered to practice before the US Patent and Trademark
Office as a Patent Attorney. Except to the extent expressly set forth in
paragraphs 4, 8, 9 and 10 below, I express no opinion with respect to any
intellectual property rights or intellectual property matters of the Company,
which are addressed in the opinion of Morgan & Finnigan, out side intellectual
property counsel to the Company.

         Based upon and subject to the limitations, qualifications, exceptions
and assumptions set forth herein, I am of the opinion that:

         1. The Company is duly qualified to transact business and is in good
standing in each jurisdiction in which the conduct of its business or its
ownership or leasing of property requires such qualification, except to the
extent that the failure to be so qualified or be in good standing could not
reasonably be expected to have a material adverse effect on the Company.

         2. The execution and delivery of the Underwriting Agreement by the
Company and the consummation by the Company


                                       5
<PAGE>

of the transactions contemplated thereby will not contravene (a) any Applicable
Law or (b) to my knowledge, except to the extent disclosed in the Prospectus,
any Material Contract; or (c) to my knowledge, any judgment, order or decree of
any court or Governmental Authority, applicable to the Company.

         3. No Governmental Approval is required by the Company for the
execution and delivery of the Underwriting Agreement or the consummation of the
transactions contemplated therein, except such as have been obtained or made.

         4. The statements in each Prospectus under the captions "Risk
Factors-We Face Potential Conflicts of Interest relating to Walker Digital,"
"Risk Factors-Our Success Depends on Our Ability to Protect Our Intellectual
Property" (other than the statements under the subheading "-Pending Interference
Action"), "Risk Factors-Regulatory and Legal Uncertainties Could Harm Our
Business," "Business-Intellectual Property," "Business-Governmental
Regulation," and "Certain Transactions" and the final four paragraphs under the
caption "Business-Legal Proceedings," in each case, insofar as such statements
constitute summaries of legal matters, legal proceedings or certain provisions
of the documents referred to therein, fairly summarize the legal matters, legal
proceedings or provisions referred to therein in all material respects.

         5. To my knowledge, except as described in each Prospectus, there are
no legal or governmental proceedings pending or threatened to which the Company
is a party or to which any of the properties of the Company is subject, the
unfavorable outcome of which could reason ably be expected to have a material
adverse effect on the Company.

         6. To my knowledge, there are no statutes or regulations applicable to
the Company or its properties or material contracts or documents to which the
Company is party, that, in either case, are required to be described in the
Registration Statement or the Prospectuses or to be filed as an exhibit to the
Registration Statement, but are not described or filed as required.


                                       6
<PAGE>

         7. The shares of Common Stock outstanding immediately prior to
issuance of the Shares (including the shares of Common Stock being sold by
certain selling stockholders in the concurrent underwritten offering of Common
Stock) have been duly authorized and are validly issued, fully paid and
non-assessable.

         8. To my knowledge, there are currently no pending or threatened claims
of infringement of any material patent, trademark, service mark or copyright or
of misappropriation of trade secrets, necessary for the Company to conduct the
business currently conducted by it, the unfavorable outcome of which could
reasonably be expected to have a material adverse effect on the Company and that
are required to be described in the Registration Statement or the Prospectuses
but are not described as required.

         9. Except as described in the Prospectuses, I have no knowledge that
the Company will be unable to continue to operate under any current license of a
patent, trade mark, service mark, copyright or trade secret, which license is
necessary for the Company to conduct the business currently conducted by it.

         10. To my knowledge, the Company owns the Patents, free and clear of
all Liens, other than those that may arise from matters disclosed in the
Prospectuses.

         This opinion is given as of the date hereof, and I assume no obligation
to update or supplement this opinion to reflect any facts or circumstances that
may come to my attention or any change in the law that may occur or become
effective after the time of delivery hereof. This opinion is provided to you as
a legal opinion only, and not as a guaranty or warranty of the matters discussed
herein or of any transaction or obligation.

         This opinion is furnished to you solely for your benefit in connection
with the closing under the Under writing Agreement occurring today and is not to
be used, circulated, quoted or otherwise referred to for any


                                       7

other purpose or relied upon by any other person without my express written
permission.

                                                      Very truly yours,


                                                      Melissa M. Taub

                  (aa) The Company has reviewed its operations to the extent and
         in the manner described in the Prospectus to evaluate the extent to

                  nor shall any notice have been given of any intended or
                  potential downgrading or of any review for a possible change
                  that does not indicate the direction of the possible change,
                  in the rating accorded any of the Company's securities by any
                  "nationally recognized statistical rating organization," as
                  such term is defined for purposes of Rule 436(g)(2) under the
                  Securities Act; and

                           (ii) there shall not have occurred any change, or any
                  development involving a prospective change, in the condition,
                  financial or otherwise, or in the earnings, business or
                  operations of the Company, from that set forth in the
                  Prospectus (exclusive of any amendments or supplements thereto
                  subsequent to the date of this Agreement) that, in your
                  judgment, is material and adverse and that makes it, in your
                  judgment, impracticable to market the Securities on the terms
                  and in the manner contemplated in the Prospectus.

                  (b) The Underwriters shall have received on the Closing Date a
         certificate, dated the Closing Date and signed by Paul E. Francis, the
         Chief Financial Officer of the Company, to the effect set forth in
         Section 5(a)(i) above and to the effect that the representations and
         warranties of the Company contained in this Agreement are true and
         correct as of the Closing Date and that the Company has in all material
         respects complied with all of the agreements and satisfied all of the
         conditions on its part to be performed or satisfied hereunder on or
         before the Closing Date.

                  The officer signing and delivering such certificate may rely
         upon the best of his or her knowledge as to proceedings threatened.

                  (c) The Underwriters shall have received on the Closing Date
         an opinion of Skadden, Arps, Slate, Meagher & Flom LLP, special outside
         counsel for the Company, dated the Closing Date, to the effect set
         forth in Annex I hereto.

                  (d) The Underwriters shall have received on the Closing Date
         the opinion of Melissa Taub, general counsel for the Company, dated the
         Closing Date, to the effect set forth in Annex II hereto.

                  (e) The Underwriters shall have received on the Closing Date
         the opinion of outside patent counsel for the Company, dated the
         Closing Date, to the effect set forth in Annex IV hereto.


                                       11
<PAGE>

                  (f) The Underwriters shall have received on the Closing Date
         an opinion of Davis Polk & Wardwell, counsel for the Underwriters,
         dated the Closing Date, in form and substance satisfactory to you.

                  The opinions described in Sections 5(c), 5(d), and 5(e) above
         shall be rendered to the Underwriters at the request of the Company.

                  (g) The Underwriters shall have received, on each of the date
         hereof and the Closing Date, a letter dated the date hereof or the
         Closing Date, as the case may be, in form and substance satisfactory to
         the Underwriters, from Deloitte & Touche LLP, independent public
         accountants, containing statements and information of the type
         ordinarily included in accountants' "comfort letters" to underwriters
         with respect to the financial statements and certain financial
         information contained in the Registration Statement and the Prospectus;
         PROVIDED that the letter delivered on the Closing Date shall use a
         "cut-off date" not earlier than the date hereof.

         The obligations of the Underwriters to purchase Additional Securities
hereunder are subject to the delivery to you on the Option Closing Date of such
documents as you may reasonably request with respect to the good standing of the
Company, the due authorization, execution and authentication of the Additional
Securities, the due authorization and reservation of the Underlying Securities
relating to the Additional Securities, and other matters related to the
execution and authentication of the Additional Securities and the issuance of
the Underlying Securities upon conversion of the Additional Securities.

           6. COVENANTS OF THE COMPANY. In further consideration of the
agreements of the Underwriters herein contained, the Company covenants with each
Underwriter as follows:

                  (a) To furnish to you, without charge, seven signed copies of
         the Registration Statement (including exhibits thereto) and for
         delivery to each other Underwriter a conformed copy of the Registration
         Statement (without exhibits thereto) and to furnish to you in New York
         City, without charge, prior to 3:00 p.m. New York City time on the
         business day next succeeding the date of this Agreement and during the
         period mentioned in Section 6(c) below, as many copies of the
         Prospectus and any supplements and amendments thereto or to the
         Registration Statement as you may reasonably request.

                  (b) Before amending or supplementing the Registration
         Statement or the Prospectus, to furnish to you a copy of each such


                                       12
<PAGE>

         proposed amendment or supplement and not to file any such proposed
         amendment or supplement to which you reasonably object, and to file
         with the Commission within the applicable period specified in Rule
         424(b) under the Securities Act any prospectus required to be filed
         pursuant to such Rule.

                  (c) If, during such period after the first date of the public
         offering of the Securities as in the opinion of counsel for the
         Underwriters the Prospectus is required by law to be delivered in
         connection with sales by an Underwriter or dealer, any event shall
         occur or condition exist as a result of which it is necessary to amend
         or supplement the Prospectus in order to make the statements therein,
         in the light of the circumstances when the Prospectus is delivered to a
         purchaser, not misleading, or if, in the opinion of counsel for the
         Underwriters, it is necessary to amend or supplement the Prospectus to
         comply with applicable law, forthwith to prepare, file with the
         Commission and furnish, at its own expense, to the Underwriters and to
         the dealers (whose names and addresses you will furnish to the Company)
         to which Securities may have been sold by you on behalf of the
         Underwriters and to any other dealers upon request, either amendments
         or supplements to the Prospectus so that the statements in the
         Prospectus as so amended or supplemented will not, in the light of the
         circumstances when the Prospectus is delivered to a purchaser, be
         misleading or so that the Prospectus, as amended or supplemented, will
         comply with law.

                  (d) To endeavor to qualify the Securities for offer and sale
         under the securities or Blue Sky laws of such jurisdictions as you
         shall reasonably request; PROVIDED that the Company shall not be
         obligated to file any general consent to service of process or to
         qualify as a foreign corporation or as a dealer in securities in any
         jurisdiction in which it is not so qualified or to subject itself to
         taxation in respect of doing business in any jurisdiction in which it
         is not otherwise so subject.

                  (e) To make generally available to the Company's security
         holders and to you as soon as practicable an earning statement covering
         the twelve-month period ending [September 30], 1999 that satisfies the
         provisions of Section 11(a) of the Securities Act and the rules and
         regulations of the Commission thereunder.

                  (f) Whether or not the transactions contemplated in this
         Agreement are consummated or this Agreement is terminated, to pay or
         cause to be paid the following expenses incident to the performance of
         its obligations under this Agreement, including: (i) the fees,
         disbursements


                                       13
<PAGE>

         and expenses of the Company's counsel and the Company's accountants in
         connection with the registration and delivery of the Securities under
         the Securities Act and all other fees or expenses in connection with
         the preparation and filing of the Registration Statement, any
         preliminary prospectus, the Prospectus and amendments and supplements
         to any of the foregoing, including all printing costs associated
         therewith, and the mailing and delivering of copies thereof to the
         Underwriters and dealers, in the quantities herein specified, (ii) all
         costs and expenses related to the transfer and delivery of the
         Securities to the Underwriters, including any transfer or other taxes
         payable thereon, (iii) the cost of producing any Blue Sky or legal
         investment memorandum in connection with the offer and sale of the
         Securities under state securities law and all expenses in connection
         with the qualification of the Securities for offer and sale under state
         securities law as provided in Section 6(d) hereof, including filing
         fees and the reasonable fees and disbursements of counsel for the
         Underwriters in connection with such qualification and in connection
         with the Blue Sky or legal investment memorandum, not to exceed,
         together with fees for the concurrent stock offering, $10,000, (iv) all
         filing fees and the reasonable fees and disbursements of counsel to the
         Underwriters incurred in connection with the review and qualification
         of the offering of the Securities by the NASD Regulation, Inc., not to
         exceed, together with fees for the concurrent stock offering, $10,000,
         (v) any fees charged by the rating agencies for the rating of the
         Securities, (vi) all costs and expenses incident to quotation of the
         Underlying Securities on the NASDAQ National Market, (vii) the cost of
         printing certificates representing the Securities, (viii) the costs and
         charges of any trustee, transfer agent, registrar or depositary, (ix)
         the costs and expenses of the Company relating to investor
         presentations on any "road show" undertaken in connection with the
         marketing of the offering of the Securities, including, without
         limitation, expenses associated with the production of road show slides
         and graphics, fees and expenses of any consultants engaged in
         connection with the road show presentations with the prior approval of
         the Company, travel and lodging expenses of the representatives and
         officers of the Company and any such consultants, and the cost of any
         aircraft chartered in connection with the road show, (x) all expenses
         in connection with any offer and sale of the Securities outside of the
         United States, including filing fees and the reasonable fees and
         disbursements of counsel for the Underwriters in connection with offers
         and sales outside of the United States and (xi) all other costs and
         expenses incident to the performance of the obligations of the Company
         hereunder for which provision is not otherwise made in this Section. It
         is understood, however, that except as provided in this Section,
         Section 7 entitled "Indemnity and Contribution", and the last paragraph
         of Section 9 below, the Underwriters will pay all of


                                       14
<PAGE>

         their costs and expenses, including fees and disbursements of their
         counsel, transfer taxes payable on resale of any of the Securities by
         them and any advertising expenses connected with any offers they may
         make.

                  (g) Not to release any option holder from, or in any other
         way, amend or modify the lock-up agreements entered into in connection
         with the Company's option exercise program described in the Prospectus,
         without the consent of Morgan Stanley & Co. Incorporated on behalf of
         the Underwriters, which shall not be unreasonably withheld.

                  (h) To notify Morgan Stanley & Co. Incorporated promptly upon
         receipt by the Company of any demand registration request under the
         Registration Rights Agreement so that the Underwriters may exercise
         their holdback rights under Section 6(a) of Registration Rights
         Agreement.

                  (i) To qualify the Underlying Securities for quotation on
         the NASDAQ National Market.

         7. INDEMNITY AND CONTRIBUTION. (a) The Company agrees to indemnify and
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Securities Act or
Section 20 of the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), from and against any and all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
in connection with defending or investigating any such action or claim) caused
by any untrue statement or alleged untrue statement of a material fact contained
in the Registration Statement or any amendment thereof, any preliminary
prospectus or the Prospectus (as amended or supplemented if the Company shall
have made any amendments or supplements thereto), or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein (in the case of the Prospectus, in
light of the circumstances under which they were made) not misleading, except
insofar as such losses, claims, damages or liabilities are caused by any such
untrue statement or omission or alleged untrue statement or omission based upon
information relating to any Underwriter furnished to the Company in writing by
such Underwriter through you expressly for use therein, PROVIDED, that the
foregoing indemnity agreement with respect to any preliminary prospectus or the
Prospectus shall not inure to the benefit of any Underwriter from whom the
person asserting any such losses, claims, damages or liabilities purchased
Securities, or any person controlling such Underwriter, if a copy of the
Prospectus (as then amended or supplemented, if the Company shall have made any
amendments or supplements) was not sent or given by or on behalf of such
Underwriter to such person, if required by law so to have been delivered, at or
prior to the written confirmation of the sale of the Securities to such person,
and if the Prospectus (as so amended or supplemented) would have cured the
defect giving rise to such loss, claim, damage or liability.


                                       15
<PAGE>

         (b) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement and each person, if any, who controls the Company within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Company to
such Underwriter, but only with reference to information relating to such
Underwriter furnished to the Company in writing by such Underwriter through you
expressly for use in the Registration Statement, any preliminary prospectus, the
Prospectus or any amendments or supplements thereto.

         (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to Section 7(a) or 7(b), such person (the "INDEMNIFIED PARTY")
shall promptly notify the person against whom such indemnity may be sought (the
"INDEMNIFYING PARTY") in writing and the indemnifying party, upon request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred upon receipt of reasonably
detailed invoices thereof. Such firm shall be designated in writing by Morgan
Stanley & Co. Incorporated, in the case of parties indemnified pursuant to
Section 7(a), and by the Company, in the case of parties indemnified pursuant to
Section 7(b). The indemnifying party shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been


                                       16
<PAGE>

sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

         (d) To the extent the indemnification provided for in Section 7(a) or
7(b) is unavailable to an indemnified party or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Underwriters on the
other hand from the offering of the Securities or (ii) if the allocation
provided by clause 7(d)(i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause 7(d)(i) above but also the relative fault of the Company on the one
hand and of the Underwriters on the other hand in connection with the statements
or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Underwriters on the other hand
in connection with the offering of the Securities shall be deemed to be in the
same respective proportions as the net proceeds from the offering of the
Securities (before deducting expenses) received by the Company and the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover of the Prospectus, bear to the
aggregate Public Offering Price of the Securities. The relative fault of the
Company on the one hand and the Underwriters on the other hand shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The
Underwriters' respective obligations to contribute pursuant to this Section 7
are several in proportion to the respective principal amounts of Securities they
have purchased hereunder, and not joint.

         (e) The Company and the Underwriters agree that it would not be just or
equitable if contribution pursuant to this Section 7 were determined by PRO RATA
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in Section 7(d). The amount paid or payable
by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such


                                       17
<PAGE>

action or claim. Notwithstanding the provisions of this Section 7, no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages that such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The remedies provided
for in this Section 7 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to any indemnified party at law or in
equity.

         (f) The indemnity and contribution provisions contained in this Section
7 and the representations, warranties and other statements of the Company
contained in this Agreement shall remain operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made
by or on behalf of any Underwriter or any person controlling any Underwriter or
by or on behalf of the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Securities.

         8. TERMINATION. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange or the National Association
of Securities Dealers, Inc., (ii) trading of any securities of the Company shall
have been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in your judgment, is material
and adverse and (b) in the case of any of the events specified in clauses
8(a)(i) through 8(a)(iv), such event, singly or together with any other such
event, makes it, in your judgment, impracticable to market the Securities on the
terms and in the manner contemplated in the Prospectus.

         9. EFFECTIVENESS; DEFAULTING UNDERWRITERS. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

         If, on the Closing Date, any one or more of the Underwriters shall fail
or refuse to purchase Securities that it has or they have agreed to purchase
hereunder on such date, and the aggregate principal amount of Securities which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase is


                                       18
<PAGE>

not more than one-tenth of the aggregate principal amount of the Securities to
be purchased on such date, the other Underwriters shall be obligated severally
in the proportions that the principal amount of Securities set forth opposite
their respective names in Schedule I bears to the principal amount of Securities
set forth opposite the names of all such non-defaulting Underwriters, or in such
other proportions as you may specify, to purchase the Securities which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date; PROVIDED that in no event shall the principal amount of Securities
that any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 9 by an amount in excess of one-ninth of such
principal amount of Securities without the written consent of such Underwriter.
If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Securities and the aggregate principal amount of Securities with
respect to which such default occurs is more than one-tenth of the aggregate
principal amount of Securities to be purchased on such date, and arrangements
satisfactory to you and the Company for the purchase of such Securities are not
made within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter or the Company. In any
such case either you or the Company shall have the right to postpone the Closing
Date, but in no event for longer than seven days, in order that the required
changes, if any, in the Registration Statement and in the Prospectus or in any
other documents or arrangements may be effected. If, on the Option Closing Date,
any Underwriter or Underwriters shall fail or refuse to purchase Additional
Securities and the aggregate number of Additional Securities with respect to
which such default occurs is more than one-tenth of the aggregate number of
Additional Securities to be purchased, the non-defaulting Underwriters shall
have the option to (i) terminate their obligation hereunder to purchase
Additional Securities or (ii) purchase not less than the number of Additional
Securities that such non-defaulting Underwriters would have been obligated to
purchase in the absence of such default. Any action taken under this paragraph
shall not relieve any defaulting Underwriter from liability in respect of any
default of such Underwriter under this Agreement.

         If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, or if for
any reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

         10. COUNTERPARTS. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         11. APPLICABLE LAW. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

         12. HEADINGS. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

Company of 2,000,000 shares (the "Primary Shares") of Common Stock and by the
Selling Stockholders of 3,500,000 shares of Common Stock; and (xiii) an

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999

of officers or other representatives of the Company and others, and such other
documents, certificates and records as we have deemed necessary or appropriate
as a basis for the opinions set forth herein.

                  In our examination, we have assumed the legal capacity of all
natural persons, the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photo static copies and the
authenticity of the originals of such latter documents. In making our
examination of executed documents, we have assumed that the parties thereto,
other than the Company, had the power, corporate or other, to enter into and
perform all obligations thereunder and have also assumed the due authorization
by all requisite action, corporate or other and the due execution and delivery
by such parties of such documents and the validity and binding effect thereof on
such parties. As to any facts material to the opinions ex pressed herein which
we did not independently establish or verify, we have relied upon oral or
written statements and representations of officers and other representatives of
the Company and others.

                   In rendering the opinions set forth in paragraphs 4 and 5
below, we have also assumed, with your consent, that the execution and delivery
by the Company of the Indenture and the Notes and the performance by the Company
of its obligations thereunder, do not and will not conflict with, contravene,
violate or constitute a default under (i) any lease, indenture, instrument or
other agreement to which the Company, or any property of the Company, is subject
(except that we do not make the

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 5


assumption set forth in this clause (i) with respect to the Certificate of
Incorporation, the By-Laws or the Applicable Contracts), (ii) any rule, law or
regulation to which the Company is subject (except that we do not make the
assumption set forth in this clause (ii) with respect to Applicable Laws); (iii)
any judicial or administrative order or decree of any governmental authority
(except that we do not make the assumption set forth in this clause (iii) with
respect to Applicable Orders); or (iv) any consent, approval, license,
authorization or validation of, or filing, recording or registration with any
governmental authority (except that we do not make this assumption with respect
to Governmental Approvals).

                  We do not express any opinion as to the effect on the opinions
set forth herein of (i) the compliance or noncompliance by any party (other than
the Company) with any state, federal or other laws or regulations applicable to
it or (ii) the legal or regulatory status or the nature of the business of any
party (other than the Company).

                  Our opinion set forth in paragraph 1 below as to the existence
and good standing of the Company under the laws of the State of Delaware is
based solely on our review of a certificate to such effect from the Secretary of
State of the State of Delaware.

                  In rendering the opinions set forth in paragraphs 6 and 7
below, we have assumed, with your consent, that the certificates representing
the Conversion Shares and the Primary Shares, respectively, will be manually
signed by one of the authorized officers of the Transfer Agent and Registrar for
the Common Stock and registered by such Transfer Agent and Registrar and will
conform to the specimen certificate representing Common Stock examined by us.

                  As used herein, (i) the term "Applicable Laws" means those
laws of the State of New York, the State of Delaware and the United States of
America that, in each case, in our experience, are normally applicable to

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 6


transactions of the type contemplated by the Underwriting Agreement (except for
United States, state and foreign securities or Blue Sky laws, anti-fraud laws
and the rules and regulations of the National Association of Securities Dealers,
Inc.) but without our having made any special investigation regarding any other
laws; (ii) the term "Governmental Authorities" means any federal, New York or
Delaware executive, legislative, judicial, administrative or regulatory body;
(iii) the term "Applicable Orders" means those judgments, orders or decrees of
any Governmental Authorities specifically identified to us by the Company to be
applicable to the Company, as identified on Schedule II hereto and (iv) the
term "Governmental Approval" means any consent, approval, license,
authorization or validation of, or filing, qualification or registration with,
any Governmental Authority required to be made or obtained by the Company
pursuant to Applicable Laws, other than any consent, approval, license,
authorization, validation, filing, qualification or registration which may have
become applicable as a result of your involvement in the transactions
contemplated by the Underwriting Agreement or because of your legal or
regulatory status or because of any other facts specifically pertaining to you.

                  Members of our firm are admitted to the bar in the State of
New York and the State of Delaware and we do not express any opinion as to the
laws of any other jurisdiction other than the laws of the United States of
America to the extent referred to specifically herein.

                  Based upon and subject to the limitations, qualifications,
exceptions and assumptions set forth herein, we are of the opinion that:

                  1. The Company is a corporation validly existing and in good
standing under the laws of the State of Delaware.
<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 7


                  2. The Company has the corporate power and corporate authority
to own, lease and operate its proper ties and to conduct its business as
described in the Registration Statement.

                  3. The authorized capital stock of the Company conforms as to
legal matters to the description thereof contained in the Prospectus.

                  4. The Indenture has been duly authorized, executed and
delivered by the Company and constitutes a valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms, except to
the extent that enforcement thereof may be limited by (a) bankruptcy, insolvency
(including, without limitation, all laws relating to fraudulent transfers),
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (b) general principles of equity
(regardless of whether enforcement is considered in a proceeding in equity or at
law) and except that the waiver contained in Section 5.08 of the Indenture may
be unenforceable.

                  5. The Notes have been duly authorized for issuance by the
Company and, when executed and authenticated in accordance with the terms of
the Indenture and delivered to and paid for by you in accordance with the terms
of the Underwriting Agreement, the Notes will constitute valid and binding
obligations of the Company, entitled to the benefits of the Indenture and
enforceable against the Company in accordance with their terms, except to the
extent that enforcement thereof may be limited by (a) bankruptcy, insolvency
(including, without limitation, all laws relating to fraudulent transfers),
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (b) general principles of equity
(regardless of whether enforcement is considered in a

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 8


proceeding in equity or at law) and, except that the waiver contained in Section
5.08 of the Indenture may be unenforceable.

                  6. The Conversion Shares initially issuable on conversion of
the Notes have been duly authorized and reserved for issuance by the Company
upon conversion of the Notes and (assuming payment for the Notes by you in
accordance with the Underwriting Agreement), if and when issued upon conversion
of the Notes in accordance with the terms of the Notes and the Indenture, such
Conversion Shares will be validly issued, fully paid and nonassessable; and the
issuance of the Conversion Shares will not be subject to any preemptive or
similar rights arising under the Certificate of Incorporation or the By-laws or
the General Corporation Law of the State of Delaware, in each case as currently
in effect.

                  7. The Primary Shares have been duly authorized by the
Company and, when delivered to and paid for by the Stock Underwriters in
accordance with the terms of the Stock Underwriting Agreement, will be validly
issued, fully paid and non-assessable shares of Common Stock.

                  8. The Underwriting Agreement has been duly authorized,
executed and delivered by the Company.

                  9. The execution and delivery of the Underwriting Agreement,
the Indenture and the Notes by the Company and the consummation by the Company
of the transactions contemplated thereby will not contravene (i) the Certificate
of Incorporation or the By-laws; (ii) any Applicable Law; (iii) except to the
extent disclosed in the Prospectus, any Applicable Contract; (iv) any Applicable
Order; or (v) the Act, the Rules and Regulations, the Securities Exchange
Act of 1934, as amended (the "Exchange Act") or the rules and regulations
thereunder, PROVIDED,

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 9


HOWEVER, that we express no opinion in this paragraph 9 with regard to the
anti-fraud provisions of the Act, the Rules and Regulations, the Exchange Act or
the rules and regulations thereunder or the information contained in, the
accuracy, completeness or correctness of, or the adequacy of the disclosure
contained in, the Prospectus or the Registration Statement or the responsiveness
thereof to the requirements of the Act and the Rules and Regulations,
which matters are addressed in paragraph 13 below and the second paragraph
following paragraph 14 below.

                  10. No Governmental Approval, or consent, filing, registration
or approval of or with the Commission, is required to be made or obtained by
the Company for the execution and delivery by the Company of the Underwriting
Agreement and the Indenture, the execution, issuance and delivery by the Company
of the Notes and the performance by the Company of its obligations under the
Underwriting Agreement, the Indenture and the Notes, except such as have been
obtained or made.

                  11. The statements set forth in the Prospectus under the
captions "Description of the Notes and "Description of Capital Stock" and in
Item 14 of the Registration Statement, insofar as such statements constitute
summaries of legal matters or certain provisions of the documents referred to
therein, fairly summarize the matters referred to therein in all material
respects.

                  12. Although the discussion set forth in the Prospectus under
the caption "Certain United States Federal Income Tax Considerations" does not
purport to discuss all possible United States federal income tax consequences of
the purchase, ownership, conversion and disposition of Notes, such discussion
constitutes, in all material respects, a fair summary of the United States
federal income

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 10


tax consequences of the purchase, owner ship, conversion and disposition of
Notes under current law.

                  13. The Registration Statement, at the time it became
effective, and the Prospectus, as of its date, appeared on their face to be
appropriately responsive in all material respects to the requirements of the Act
and the Rules and Regulations, except that, in each case, we express no opinion
as to the financial statements, schedules and other financial and statistical
data included therein or excluded therefrom or the exhibits thereto, and, except
to the extent expressly stated in paragraphs 11 and 12 above, we do not assume
any responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus.

                  14. The Company is not and, upon the consummation of the
transactions contemplated by the Underwriting Agreement, will not be, an
investment company under the Investment Company Act of 1940, as amended.

                  We have been orally advised by the Commission that the
Registration Statement was declared effective under the Act at ____ p.m. on
August 10, 1999. We have been orally advised by the Commission that no stop
order suspending the effectiveness of the Registration Statement has been
issued and, to the best of our knowledge, no proceedings for that purpose have
been instituted or are pending or threatened by the Commission.

                  In addition, we have participated in conferences with officers
and other representatives of the Company, representatives of the independent
accountants of the Company, your counsel and you at which the contents of the
Registration Statement and the Prospectus and related matters were discussed
and, although we are not passing upon, and do not assume any responsibility for,
the

<PAGE>

MORGAN STANLEY & CO. INCORPORATED
August 16, 1999
Page 11


accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus and have made no independent check or
verification thereof (except to the extent expressly stated in paragraphs 11
and 12 above), on the basis of the foregoing, no facts have come to our
attention that have led us to believe that the Registration Statement, at the
time it became effective, contained an untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, or that the Prospectus, as of its
date and as of the date hereof, contained or contains an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading, except that we express no opinion or belief with respect
to the financial statements, schedules and other financial and statistical data
included therein or excluded therefrom or the exhibits to the Registration
Statement.

                  This opinion is furnished to you solely for your benefit in
connection with the closing under the Underwriting Agreement occurring today and
is not to be used, circulated, quoted or otherwise referred to for any other
purpose or relied upon by any other person without our express written
permission.


                                                    Very truly yours,

     ------------------------------------------------

Ladies and Gentlemen:

         I am Senior Vice President, General Counsel and Secretary of
priceline.com Incorporated, a Delaware corporation (the "Company"), and have
acted as general counsel to the Company in connection with the Underwriting
Agreement, dated August 10, 1999 (the "Underwriting Agreement"), between the
Company and Morgan Stanley & Co. Incorporated, Goldman Sachs & Co., Allen &
Company Incorporated, BancBoston Robertson Stephens Inc., Donaldson, Lufkin &
Jenrette Securities Corporation and Merrill Lynch, Pierce, Fenner & Smith
Incorporated as representatives of the several Underwriters named

<PAGE>

therein (the "Underwriters"), relating to the sale by the Company to the several
Underwriters of $250,000,000 aggregate principal amount of the Company's ____%
Convertible Subordinated Notes due 2006 (the "Notes").

         This opinion is being furnished pursuant to Section 5(d) of the
Underwriting Agreement.

         In connection with this opinion, I have examined originals or copies,
certified or otherwise identified to my satisfaction, of (i) the Registration
Statement on Form S-1 (File No. 333-83513) relating to the Notes, filed with the
Securities and Exchange Commission (the "Commission") on July 23, 1999 under the
Securities Act of 1933, as amended (the "Act"), Amendment No. 1 thereto filed
with the Commission on August 2, 1999 and Amendment No. 2 thereto filed with the
Commission on August [9][10], 1999, including information deemed to be a part of
the registration statement at the time of effectiveness pursuant to Rule 430A
of the General Rules and Regulations under the Act (the "Rules and Regulations")
(such Registration Statement, as so amended, being here inafter referred to as
the "Registration Statement"); (ii) the final prospectus dated August 10, 1999
relating to the Notes and the shares of common stock, par value $.008 per share
("Common Stock"), of the Company issuable upon conversion of the Notes, in the
form filed with the Commission pursuant to Rule 424(b) of the Rules and
Regulations (the "Prospectus"); (iii) a form of global certificate representing
the Notes; (iv) a specimen certificate representing Common Stock; (v) an
executed copy of the Underwriting Agreement; (vi) an executed copy of the
indenture, dated as of August 13, 1999 (the "In denture"), between the Company
and Wilmington Trust Company, as trustee (the "Trustee"); (vii) the Certificate
of Incorporation of the Company, as currently in effect (the "Certificate of
Incorporation"); (viii) the By-laws of the Company, as currently in effect (the
"Bylaws"); (ix) certain resolutions of the Board of Directors of the Company
and a Pricing Committee of the Board of Directors of the Company; (x) a
certificate of the Chief Executive Officer and Chief Financial Officer of the
Company as to the factual matters covered thereby, a copy of which is attached
hereto (the


                                       2
<PAGE>

"Officers' Certificate"); (ix) the agreements included as exhibits to the
Registration Statement (the "Material Contracts"); and (x) certain documents
purporting to assign the rights to United States patents No. 5,794,207 and No.
5,797,127 (collectively, the "Patents") to the Company. I have also examined
originals or copies, certified or otherwise identified to my satisfaction, of
such records of the Company and such agreements, certificates of public
officials, certificates of officers or other representatives of the Company and
others, and such other documents, certificates and records as I have deemed
necessary or appropriate as a basis for the opinions set forth herein.

         In my examination, I have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to me as originals, the conformity to original documents of all
documents submitted to me as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents. In making my examination
of executed documents, I have assumed that the parties thereto, other than the
Company, had the power, corporate or other, to enter into and perform all
obligations thereunder and I have also assumed the due authorization by all
requisite action, corporate or other, and execution and delivery by such
parties of such documents and the validity and binding effect thereof on such
parties.

         As used herein, (i) the term "Applicable Laws" means the General
Corporation Law of the State of Delaware and those laws of the State of
Connecticut and the United States of America that, in each instance, are
normally applicable to transactions of the type contemplated by the Underwriting
Agreement (except for United States, state and foreign securities or Blue Sky
laws, anti-fraud laws, laws affecting creditors rights generally and the rules
and regulations of the National Association of Securities Dealers, Inc.) but
without my having made any investigation regarding any other laws; (ii) the term
"Governmental Authorities" means any federal or Connecticut executive,
legislative, administrative or regulatory body and the Secretary of State of the
State of Delaware and (iii) the term "Governmental Approval"


                                       3
<PAGE>

means any consent, approval, license, authorization or validation of, or filing,
qualification or registration with, any Governmental Authority required to be
obtained or made by the Company pursuant to Applicable Laws, other than any
consent, approval, license, authorization, validation, filing, qualification or
registration which may have become applicable as a result of your involvement in
the transactions contemplated by the Underwriting Agreement or because of your
legal or regulatory status or because of any other facts specifically pertaining
to you.

         In providing the opinions set forth in paragraphs 2, 5, 6, 8, 9 and 10
below, I have made no investigation or search of public docket records of any
court, governmental or administrative agency or body, or of any filings,
applications or registrations with the United States Patent and Trademark Office
or the United States Copy right Office.

         For the purposes of the opinions set forth in paragraphs 2, 5, 6, 8, 9
and 10 below, the expressions "to my knowledge" and "I have no knowledge" are
each limited to those matters brought to my attention after reasonable inquiry
of officers of the Company.

         For the purposes of the opinion set forth in paragraph 10 below, the
term "Liens" means all presently asserted liens or other encumbrances.

         Insofar as the opinion in paragraph 1 below relates to the laws of the
States of California, Ohio, New Jersey or New York [ANY OTHERS?], I have relied
solely on certificates of due qualification and good standing from the
Secretary of State of each such state.

         I am the Senior Vice President, General Counsel and Secretary of the
Company, and have held such position since September 1998. I am admitted to the
bar in the State of Connecticut and, except to the extent set forth in the
preceding paragraph, I do not express any opinion as to the laws of any other
jurisdiction other than the General Corporation Law of the State of Delaware and
the laws of the


                                       4
<PAGE>

United States of America to the extent referred to specifically herein. I am not
registered to practice before the US Patent and Trademark Office as a Patent
Attorney. Except to the extent expressly set forth in paragraphs 4, 8, 9 and 10
below, I express no opinion with respect to any intellectual property rights or
intellectual property matters of the Company, which are addressed in the opinion
of Morgan & Finnigan, outside intellectual property counsel to the Company.

         Based upon and subject to the limitations, qualifications, exceptions
and assumptions set forth herein, I am of the opinion that:

         1. The Company is duly qualified to transact business and is in good
standing in each jurisdiction in which the conduct of its business or its
ownership or leasing of property requires such qualification, except to the
extent that the failure to be so qualified or be in good standing could not
reasonably be expected to have a material adverse effect on the Company.

         2. The execution and delivery of the Underwriting Agreement, the
Indenture and the Notes by the Company and the consummation by the Company of
the transactions contemplated thereby will not contravene (a) any Applicable
Law or (b) to my knowledge, except to the extent disclosed in the Prospectus,
any Material Contract; or (c) to my knowledge, any judgment, order or decree of
any court or Governmental Authority, applicable to the Company.

         3. No Governmental Approval is required by the Company for the
execution and delivery of the Underwriting Agreement, the Indenture or the
Notes, or for the consummation of the transactions contemplated therein, except
such as have been obtained or made.

         4. The statements in the Prospectus under the captions "Risk Factors-We
Face Potential Conflicts of Interest Relating to Walker Digital," "Risk
Factors-Our Success Depends on Our Ability to Protect Our Intellectual
Property"


                                       5
<PAGE>

(other than the statements under the subheading "-Pending Interference Action"),
"Risk Factors-Regulatory and Legal Uncertainties Could Harm Our Business,"
"Business-Intellectual Property," "Business-Governmental Regulation," and
"Certain Transactions" and the final four paragraphs under the caption
"Business-Legal Proceedings," in each case, insofar as such statements
constitute summaries of legal matters, legal proceedings or certain provisions
of the documents referred to therein, fairly summarize the legal matters, legal
proceedings or provisions referred to therein in all material respects.

         5. To my knowledge, except as described in the Prospectus, there are no
legal or governmental proceedings pending or threatened to which the Company is
a party or to which any of the properties of the Company is subject, the
unfavorable outcome of which could reason ably be expected to have a material
adverse effect on the Company.

         6. To my knowledge, there are no statutes or regulations applicable to
the Company or its properties or material contracts or documents to which the
Company is party, that, in either case, are required to be described in the
Registration Statement or the Prospectus or to be filed as an exhibit to the
Registration Statement, but are not described or filed as required.

         7. The shares of Common Stock outstanding immediately prior to
issuance of the Notes (including the shares of Common Stock being sold by
certain selling stockholders in the concurrent underwritten offering of Common
Stock) have been duly authorized and are validly issued, fully paid and
non-assessable.

         8. To my knowledge, there are currently no pending or threatened claims
of infringement of any material patent, trademark, service mark or copyright or
of misappropriation of trade secrets, necessary for the Company to conduct the
business currently conducted by it, the unfavorable outcome of which could
reasonably be expected to have a material adverse effect on the Company and that
are required to be


                                       6
<PAGE>

described in the Registration Statement or the Prospectus but are not described
as required.

         9. Except as described in the Prospectus, I have no knowledge that the
Company will be unable to continue to operate under any current license of a
patent, trademark, service mark, copyright or trade secret, which license is
necessary for the Company to conduct the business currently conducted by it.

         10. To my knowledge, the Company owns the Patents, free and clear of
all Liens, other than those that may arise from matters disclosed in the
Prospectus.

         This opinion is given as of the date hereof, and I assume no obligation
to update or supplement this opinion to reflect any facts or circumstances that
may come to my attention or any change in the law that may occur or become
effective after the time of delivery hereof. This opinion is provided to you as
a legal opinion only, and not as a guaranty or warranty of the matters discussed
herein or of any transaction or obligation.

         This opinion is furnished to you solely for your benefit in connection
with the closing under the Under writing Agreement occurring today and is not to
be used, circulated, quoted or otherwise referred to for any other purpose or
relied upon by any other person without my express written permission.


                                                       Very truly yours,

<PAGE>



         SECTION 2.02. FORM OF NOTES. The Notes and the Trustee's certificate of
authentication to be borne by such Notes shall be substantially in the form set
forth in Exhibit A, which is incorporated in and made a part of this Indenture.

         Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends and endorsements as the officers
executing the same may approve (execution thereof to be conclusive evidence of
such approval) and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be
listed, or to conform to usage.

         Any Global Note shall represent such of the outstanding Notes as shall
be specified therein and shall provide that it shall represent the aggregate
amount of outstanding Notes from time to time endorsed thereon and that the
aggregate amount of outstanding Notes represented thereby may from time to time
be increased or reduced to reflect transfers or exchanges permitted hereby. Any
endorsement of a Global Note to reflect the amount of any increase or decrease
in the amount of outstanding Notes represented thereby shall be made by the
Trustee or the Custodian, at the direction of the Trustee, in such manner and
upon instructions given by the holder of such Notes in accordance with this
Indenture. Payment of principal of and interest and premium, if any, on any
Global Note shall be made to the holder of such Global Note.

         The terms and provisions contained in the form of Note attached as
Exhibit A hereto shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby.

         SECTION 2.03. DATE AND DENOMINATION OF NOTES; PAYMENTS OF INTEREST. The
Notes shall be issuable in registered form without coupons in denominations of
$1,000 principal amount and integral multiples thereof. Every Note shall be
dated the date of its authentication and shall bear interest from the applicable
date in each case as specified on the face of the form of Note attached as
Exhibit A hereto. Interest on the Notes shall be computed on the basis of a
360-day year comprised of twelve (12) 30-day months.

         The Person in whose name any Note (or its Predecessor Note) is
registered on the Note register at the close of business on any record date with
respect to any interest payment date shall be entitled to receive the interest
payable on such interest payment date, except that the interest payable upon
redemption will be


                                       9
<PAGE>



payable only to the Person to whom principal is payable pursuant to such
redemption (unless the date of redemption is an interest payment date, in which
case the semi-annual payment of interest becoming due on such date shall be
payable to the holders of such Notes registered as such on the relevant record
date). Notwithstanding the foregoing, if any Note (or portion thereof) is
converted into Common Stock during the period from (but excluding) a record date
to (but excluding) the next succeeding interest payment date and such Note (or
portion thereof) has been called for redemption on a redemption date which
occurs during such period, the Company shall not be required to pay interest on
such interest payment date in respect of any such Note (or portion thereof).
Interest may, as the Company shall specify to the paying agent in writing by
each record date, be paid either (i) by check mailed to the address of the
Person entitled thereto as it appears in the Note register or (ii) by transfer
to an account maintained by such Person located in the United States if such
Person has notified the Company of the details of such account at least seven
(7) days prior to a scheduled interest payment date; PROVIDED that payments to
the Depositary will be made by wire transfer of immediately available funds to
the account of the Depositary or its nominee. The term "RECORD DATE" with
respect to any interest payment date shall mean the January 15 or July 15
preceding said February 1 or August 1, respectively.

         Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any said February 1 or August 1 (herein called
"DEFAULTED INTEREST") shall forthwith cease to be payable to the Noteholder on
the relevant record date by virtue of his having been such Noteholder; and such
Defaulted Interest shall be paid by the Company, at its election in each case,
as provided in clause (a) or (b) below;

              (a) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Notes (or their respective
         Predecessor Notes) are registered at the close of business on a
         special record date for the payment of such Defaulted Interest, which
         shall be fixed in the  following manner. The Company shall notify the
         Trustee in writing of the amount of Defaulted Interest to be paid on
         each Note and the date of the payment (which shall be not less than
         twenty-five (25) days after the receipt by the Trustee of such notice,
         unless the Trustee shall consent to an earlier date), and at the same
         time the Company shall deposit with the Trustee an amount of money
         equal to the aggregate amount to be paid in respect of such
         Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause
         provided. Thereupon the Trustee shall fix a special record date for
         the


                                       10
<PAGE>



         payment of such Defaulted Interest which shall be not more than fifteen
         (15) days and not less than ten (10) days prior to the date of the
         proposed payment, and not less than ten (10) days after the receipt by
         the Trustee of the notice of the proposed payment, the Trustee shall
         promptly notify the Company of such special record date and, in the
         name and at the expense of the Company, shall cause notice of the
         proposed payment of such Defaulted Interest and the special record date
         therefor to be mailed, first-class postage prepaid, to each Noteholder
         at his address as it appears in the Note register, not less than ten
         (10) days prior to such special record date. Notice of the proposed
         payment of such Defaulted Interest and the special record date therefor
         having been so mailed, such Defaulted Interest shall be paid to the
         Persons in whose names the Notes (or their respective Predecessor
         Notes) were registered at the close of business on such special record
         date and shall no longer be payable pursuant to the following clause
         (b) of this Section 2.03.

              (b) The Company may make payment of any Defaulted Interest in any
         other lawful manner not inconsistent with the requirements of any
         securities exchange or automated quotation system on which the Notes
         may be listed or designated for issuance, and upon such notice as may
         be required by such exchange or automated quotation system, if, after
         notice given by the Company to the Trustee of the proposed payment
         pursuant to this clause, such manner of payment shall be deemed
         practicable by the Trustee.

         SECTION 2.04. EXECUTION OF NOTES. The Notes shall be signed in the name
and on behalf of the Company by the manual or facsimile signature of its Chief
Executive Officer, President, Chief Financial Officer, any Executive or Senior
or any Vice President (whether or not designated by a number or numbers or word
or words added before or after the title "Vice President") and attested by the
manual or facsimile signature of its Secretary or any of its Assistant
Secretaries or Treasurer or any of its Assistant Treasurers (which may be
printed, engraved or otherwise reproduced thereon, by facsimile or otherwise).
Only such Notes as shall bear thereon a certificate of authentication
substantially in the form set forth on the form of Note attached as Exhibit A
hereto, manually executed by the Trustee (or an authenticating agent appointed
by the Trustee as provided by Section 16.11), shall be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose. Such certificate by
the Trustee (or such an authenticating agent) upon any Note executed by the
Company shall be conclusive evidence that the Note so authenticated has been
duly authenticated and delivered hereunder and that the holder is entitled to
the benefits of this Indenture.


                                       11
<PAGE>



         In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the Person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such Persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
Person was not such an officer.

          SECTION 2.05. EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES; GLOBAL
NOTES; DEPOSITARY.

          (a) The Company shall cause to be kept at the Corporate Trust Office a
register (the register maintained in such office and in any other office or
agency of the Company designated pursuant to Section 5.02 being herein sometimes
collectively referred to as the "NOTE REGISTER") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and of transfers of Notes. The Note register shall be in
written form or in any form capable of being converted into written form within
a reasonably prompt period of time. The Trustee is hereby appointed "NOTE
REGISTRAR" for the purpose of registering Notes and transfers of Notes as herein
provided. The Company may appoint one or more co-registrars in accordance with
Section 5.02.

         Upon surrender for registration of transfer of any Note to the Note
registrar or any co-registrar, and satisfaction of the requirements for such
transfer set forth in this Section 2.05, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denominations and of a
like aggregate principal amount.

         Notes may be exchanged for other Notes of any authorized denominations
and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency maintained by the Company pursuant to
Section 5.02. Whenever any Notes are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Notes which
the Noteholder making the exchange is entitled to receive bearing registration
numbers not contemporaneously outstanding.

         All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and

                                     12

<PAGE>
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

         All Notes presented or surrendered for registration of transfer or for
exchange, redemption or conversion shall (if so required by the Company or the
Note registrar) be duly endorsed, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Trustee, and
the Notes shall be duly executed by the Noteholder thereof or his attorney duly
authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax, assessment or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes.

         Neither the Company nor the Trustee nor any Note registrar shall be
required to exchange or register a transfer of (i) any Notes for a period of
fifteen (15) days next preceding any selection of Notes to be redeemed or (ii)
any Notes or portions thereof called for redemption pursuant to Section 3.02 or
(iii) any Notes or portion thereof surrendered for conversion pursuant to
Article 15 or (iv) any Notes or portions thereof tendered for redemption (and
not withdrawn) pursuant to Section 3.05.

          (b) So long as the Notes are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, all Notes will be
represented by one or more Notes in global form registered in the name of the
Depositary or the nominee of the Depositary (the "GLOBAL NOTE"), except as
otherwise specified below. The transfer and exchange of beneficial interests in
any such Global Note shall be effected through the Depositary in accordance with
this Indenture and the procedures of the Depositary therefor. Except as provided
below, beneficial owners of a Global Note shall not be entitled to have
certificates registered in their names, will not receive or be entitled to
receive physical delivery of certificates in definitive form and will not be
considered holders of Global Notes.

         Notwithstanding any other provisions of this Indenture, a Global Note
may not be transferred as a whole or in part except by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

         The Depositary shall be a clearing agency registered under the Exchange
Act. The Company initially appoints The Depository Trust Company to act as
Depositary with respect to the Global Notes. Initially, each Global Note shall
be


                                       13
<PAGE>



issued to the Depositary, registered in the name of Cede & Co., as the nominee
of the Depositary, and deposited with the Custodian for Cede & Co.

         Holders of beneficial interests in a Global Note shall have no rights
under this Indenture with respect to any Global Note held on their behalf by the
Depositary, and the Depositary may be treated by the Company, the Trustee, any
registrar, any paying agent and any conversion agent as the absolute owner and
holder of such Global Note for all purposes whatsoever. Neither the Company, the
Trustee nor any paying agent shall have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
interests in any Global Note or for maintaining, supervising or reviewing any
records relating to any beneficial interests in any Global Note. Notwithstanding
the foregoing, the Depositary or its nominee may grant proxies and otherwise
authorize any person (including any direct or indirect participant of the
Depositary and any person that holds a beneficial interest in a Global Note
through such a direct or indirect participant) to take any action which a holder
is entitled to take under this Indenture or the Notes and nothing herein shall
impair, as between the Depositary and its direct or indirect participants, the
operation of customary practices governing the exercise of the rights of a
holder of any security.

         If at any time the Depositary for a Global Note notifies the Company
that it is unwilling or unable to continue as Depositary for such Note, the
Company may appoint a successor Depositary with respect to such Note. If a
successor Depositary is not appointed by the Company within ninety (90) days
after the Company receives such notice, the Company will execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of Notes, will authenticate and deliver, Notes in definitive form, in
aggregate principal amount equal to the principal amount of such Global Note, in
exchange for such Global Note.

         The Company may at any time in its sole discretion determine that Notes
issued in the form of one or more Global Notes shall no longer be represented by
such Global Notes. In such event the Company will execute, and the Trustee, upon
receipt of a Company order for the authentication and delivery of individual
Notes of such series in exchange in whole or in part of such Global Note, will
authenticate and deliver individual Notes of such series of like tenor and terms
in a definitive form in an aggregate principal amount equal to the principal
amount of such Global Note or Notes representing such series in exchange for
such Global Note or Notes.

         If a Note in definitive form is issued in exchange for any portion of a
Global Note after the close of business at the office or agency where such
exchange occurs on any record date and before the opening of business at such


                                       14
<PAGE>



office or agency on the next succeeding interest payment date, interest will not
be payable on such interest payment date in respect of such definitive Note, but
will be payable on such interest payment date, subject to the provisions of
Section 2.03, only to the Person to whom interest in respect of such portion of
such Global Note is payable in accordance with the provisions of this Indenture.

         Notes in definitive form issued in exchange for all or a part of a
Global Note pursuant to this Section 2.05 shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. Upon execution and authentication, the Trustee shall deliver such Notes
in definitive form to the Persons in whose names such Notes in definitive form
are so registered.

         At such time as all interests in a Global Note have been redeemed,
converted, canceled, exchanged for Notes in definitive form, or transferred to a
transferee who receives Notes in definitive form, such Global Note shall, upon
receipt thereof, be canceled by the Trustee in accordance with standing
procedures and instructions existing between the Depositary and the Custodian.
At any time prior to such cancellation, if any interest in a Global Note is
redeemed, converted, repurchased or canceled, exchanged for Notes in definitive
form or transferred to a transferee who receives Notes in definitive form
therefor or any Note in definitive form is exchanged or transferred for part of
a Global Note, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary
and the Custodian, be appropriately reduced or increased, as the case may be,
and an endorsement shall be made on such Global Note, by the Trustee or the
Custodian, at the direction of the Trustee, to reflect such reduction or
increase.

         SECTION 2.06. MUTILATED, DESTROYED, LOST OR STOLEN NOTES. In case any
Note shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its written request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and make
available for delivery, a new Note, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of
and in substitution for the Note so destroyed, lost or stolen. In every case the
applicant for a substituted Note shall furnish to the Company, to the Trustee
and, if applicable, to such authenticating agent, such security or indemnity as
may be required by them to save each of them harmless for any loss, liability,
cost or expense caused by or connected with such substitution, and, in every
case of destruction, loss or theft, the applicant shall also furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent
evidence to their


                                       15
<PAGE>



satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof.

         Following receipt by the Company, the Trustee or such authenticating
agent, as the case may be, of satisfactory security or indemnity and evidence,
as described in the preceding paragraph, the Trustee or such authenticating
agent may authenticate any such substituted Note and make available for delivery
such Note. Upon the issuance of any substituted Note, the Company may require
the payment of a sum sufficient to cover any tax, assessment or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Note which has matured or is about to
mature or has been called for redemption or has been tendered for redemption
(and not withdrawn) or is about to be converted into Common Stock shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Note, pay or authorize the payment of or convert or authorize the
conversion of the same (without surrender thereof except in the case of a
mutilated Note), as the case may be, if the applicant for such payment or
conversion shall furnish to the Company, to the Trustee and, if applicable, to
such authenticating agent, such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or expense caused by
or connected with such substitution, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Company, the Trustee and, if
applicable, any paying agent or conversion agent, evidence to their satisfaction
of the destruction, loss or theft of such Note and of the ownership thereof.

         Every substitute Note issued pursuant to the provisions of this Section
2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder. To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment or conversion of negotiable
instruments or other securities without their surrender.

         SECTION 2.07.  TEMPORARY NOTES.  Pending the preparation of Notes in
definitive form, the Company may execute and the Trustee or an authenticating
agent appointed by the Trustee shall, upon the written request of the Company,
authenticate and deliver temporary Notes (printed or lithographed).  Temporary


                                       16
<PAGE>



Notes shall be issuable in any authorized denomination, and substantially in the
form of the Notes in definitive form, but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as
the Notes in definitive form. Without unreasonable delay the Company will
execute and deliver to the Trustee or such authenticating agent Notes in
definitive form (other than in the case of Global Notes) and thereupon any or
all temporary Notes (other than any such Global Note) may be surrendered in
exchange therefor, at each office or agency maintained by the Company pursuant
to Section 5.02 and the Trustee or such authenticating agent shall authenticate
and make available for delivery in exchange for such temporary Notes an equal
aggregate principal amount of Notes in definitive form. Such exchange shall be
made by the Company at its own expense and without any charge therefor. Until so
exchanged, the temporary Notes shall in all respects be entitled to the same
benefits and subject to the same limitations under this Indenture as Notes in
definitive form authenticated and delivered hereunder.

         SECTION 2.08. CANCELLATION OF NOTES PAID, ETC. All Notes surrendered
for the purpose of payment, redemption, conversion, exchange or registration of
transfer shall, if surrendered to the Company or any paying agent or any Note
registrar or any conversion agent, be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by
it, and no Notes shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Indenture. The Trustee shall return such
canceled Notes to the Company. If the Company shall acquire any of the Notes,
such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Notes unless and until the same are delivered
to the Trustee for cancellation.

         SECTION 2.09. CUSIP NUMBERS. The Company in issuing the Notes shall use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use
CUSIP numbers in notices of redemption as a convenience to Noteholders; PROVIDED
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the CUSIP numbers.

                                    ARTICLE 3
                               REDEMPTION OF NOTES

         SECTION 3.01. REDEMPTION PRICES. The Company may not redeem the Notes
prior to August 6, 2002. At any time on or after August 6, 2002, the Company
may, at its option, redeem all or from time to time any part of the Notes on any
date prior to maturity, upon notice as set forth in Section 3.02, and at the
optional redemption prices set forth in the form of Note attached as Exhibit A
hereto, together with accrued interest to, but excluding, the date fixed for
redemption.

         SECTION 3.02. NOTICE OF REDEMPTION; SELECTION OF NOTES. In case the
Company shall desire to exercise the right to redeem all or, as the case may be,
any part of the Notes pursuant to Section 3.01, it shall fix a date for
redemption and it or, at its written request received by the Trustee not fewer
than thirty (30) days prior (or such shorter period of time as may be acceptable
to the Trustee) to the date fixed for redemption, the Trustee in the name of and
at the expense of the Company, shall mail or cause to be mailed a notice of such
redemption at least thirty (30) but not more than sixty (60) days prior to the
date fixed for redemption to the holders of Notes so to be redeemed as a whole
or in part at their last addresses as the same appear on the Note register;
PROVIDED that if the Company shall give such notice, it shall also give written
notice, and written notice of the Notes to be redeemed, to the Trustee. Such
mailing shall be by first class mail. The notice if mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives such notice. The Company shall also publish notice of any
such redemption in Bloomberg Business News, DowJones News and Reuters Financial
Report in New York City. In any case, failure to give such notice by mail or any
defect in the notice to the holder of any Note designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Note.

         Each such notice of redemption shall specify the aggregate principal
amount of Notes to be redeemed, the CUSIP numbers, the date fixed for redemption
(which shall be a Business Day), the redemption price at which Notes are to be
redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Notes, that interest accrued to the date
fixed for redemption will be paid as specified in said notice, and that on and
after said date interest thereon or on the portion thereof to be redeemed will
cease to accrue. Such notice shall also state the current Conversion Price and
the date on which the right to convert such Notes or portions thereof into
Common Stock will expire. If fewer than all the Notes are to be redeemed, the
notice of redemption shall identify the Notes to be redeemed (including CUSIP
numbers, if any). In


                                       18
<PAGE>



case any Note is to be redeemed in part only, the notice of redemption shall
state the portion of the principal amount thereof to be redeemed and shall state
that, on and after the date fixed for redemption, upon surrender of such Note, a
new Note or Notes in principal amount equal to the unredeemed portion thereof
will be issued.

         On or prior to the redemption date specified in the notice of
redemption given as provided in this Section 3.02, the Company will deposit with
the Trustee or with one or more paying agents (or, if the Company is acting as
its own paying agent, set aside, segregate and hold in trust as provided in
Section 5.04) an amount of money sufficient to redeem on the redemption date all
the Notes (or portions thereof) so called for redemption (other than those
theretofore surrendered for conversion into Common Stock) at the appropriate
redemption price, together with accrued interest to, but excluding, the date
fixed for redemption; PROVIDED that if such payment is made on the redemption
date it must be received by the Trustee or paying agent, as the case may be, by
10:00 a.m. New York City time, on such date. If any Note called for redemption
is converted into Common Stock pursuant to the terms hereof, any money deposited
with the Trustee or any paying agent or so segregated and held in trust for the
redemption of such Note shall be paid to the Company upon its written request,
or, if then held by the Company shall be discharged from such trust. Whenever
any Notes are to be redeemed, the Company will give the Trustee written notice
in the form of an Officers' Certificate not fewer than thirty (30) days (or such
shorter period of time as may be acceptable to the Trustee) prior to the
redemption date as to the aggregate principal amount of Notes to be redeemed.

         If fewer than all the outstanding Notes are to be redeemed, the Trustee
shall select the Notes (or portions thereof) to be redeemed (in principal
amounts of $1,000 or integral multiples thereof), by lot, on a pro rata basis or
by another method the Trustee deems fair and appropriate. If any Note selected
for partial redemption is converted in part after such selection, the converted
portion of such Note shall be deemed (so far as may be) to be the portion to be
selected for redemption. The Notes (or portions thereof) so selected shall be
deemed duly selected for redemption for all purposes hereof, notwithstanding
that any such Note is converted as a whole or in part before the mailing of the
notice of redemption.

         Upon any redemption of less than all of the outstanding Notes, the
Company and the Trustee may (but need not) treat as outstanding any Notes
surrendered for conversion during the period of fifteen (15) days next preceding
the mailing of a notice of redemption and may (but need not) treat as
outstanding any Note authenticated and delivered during such period in exchange
for the unconverted portion of any Note converted in part during such period.

         SECTION 3.03. PAYMENT OF NOTES CALLED FOR REDEMPTION. If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date fixed for
redemption and at the place or places stated in such notice at the applicable
redemption price, together with interest accrued to (but excluding) the date
fixed for redemption, and on and after said date (unless the Company shall
default in the payment of such Notes at the redemption price, together with
interest accrued to said date), interest on the Notes or portion of Notes so
called for redemption shall cease to accrue and such Notes shall cease after the
close of business on the Business Day next preceding the date fixed for
redemption to be convertible into Common Stock and, except as provided in
Sections 8.05 and 13.04, to be entitled to any benefit or security under this
Indenture, and the holders thereof shall have no right in respect of such Notes
except the right to receive the redemption price thereof and unpaid interest to
(but excluding) the date fixed for redemption. On presentation and surrender of
such Notes at a place of payment in said notice specified, the said Notes or the
specified portions thereof shall be paid and redeemed by the Company at the
applicable redemption price, together with interest accrued thereon to (but
excluding) the date fixed for redemption; PROVIDED that, if the applicable
redemption date is an interest payment date, the semi-annual payment of interest
becoming due on such date shall be payable to the holders of such Notes
registered as such on the relevant record date instead of the holders
surrendering such Notes for redemption on such date.

         Upon presentation of any Note redeemed in part only, the Company shall
execute and the Trustee shall authenticate and make available for delivery to
the holder thereof, at the expense of the Company, a new Note or Notes, of
authorized denominations, in principal amount equal to the unredeemed portion of
the Notes so presented.

         Notwithstanding the foregoing, the Trustee shall not redeem any Notes
or mail any notice of optional redemption during the continuance of a default in
payment of principal, premium, if any, or interest on the Notes or any other
Event of Default of which a Responsible Officer of the Trustee has knowledge,
unless all such defaults and Events of Default are cured at the time of
redemption. If any Note called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and premium, if any, shall,
until paid or duly provided for, bear interest from the date fixed for
redemption at the rate borne by the Note and such Note shall remain convertible
into Common Stock until the principal and premium, if any, and interest shall
have been paid or duly provided for.

         SECTION 3.04.  CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.  In
connection with any redemption of Notes, the Company may arrange for the


                                       20
<PAGE>



purchase and conversion of any Notes by an agreement with one or more investment
bankers or other purchasers to purchase such Notes by paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount
not less than the applicable redemption price, together with interest accrued to
(but excluding) the date fixed for redemption, of such Notes. Notwithstanding
anything to the contrary contained in this Article 3, the obligation of the
Company to pay the redemption price of such Notes, together with interest
accrued to (but excluding) the date fixed for redemption, shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, a copy of which will be filed
with the Trustee prior to the date fixed for redemption, any Notes not duly
surrendered for conversion by the holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything to the contrary
contained in Article 15) surrendered by such purchasers for conversion, all as
of immediately prior to the close of business on the date fixed for redemption
(and the right to convert any such Notes shall be extended through such time),
subject to payment of the above amount as aforesaid. At the direction of the
Company, the Trustee shall hold and dispose of any such amount paid to it in the
same manner as it would monies deposited with it by the Company for the
redemption of Notes. Without the Trustee's prior written consent, no arrangement
between the Company and such purchasers for the purchase and conversion of any
Notes shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture.

          SECTION 3.05. REDEMPTION AT OPTION OF HOLDERS.

          (a) If there shall occur a Fundamental Change at any time prior to
August 1, 2006, then each Noteholder shall have the right, at such holder's
option, to require the Company to redeem all of such holder's Notes, or any
portion thereof that is an integral multiple of $1,000 principal amount, on the
date (the "REPURCHASE DATE") that is thirty (30) days after the date of the
Company Notice (as defined in Section 3.05(b) below) of such Fundamental Change
(or, if such 30th day is not a Business Day, the next succeeding Business Day).
Such repayment shall be made at a price equal to 100% of the principal amount to
be redeemed. The Company shall also pay to such holders accrued interest on the
redeemed Notes to, but excluding, the Repurchase Date; PROVIDED that, if such
Repurchase Date is an interest payment date, the semi-annual payment of interest
becoming due on such date shall be paid to the holders of such Notes registered
as such on the relevant record date instead of the holders surrendering such
Notes for redemption on such date.



                                       21
<PAGE>



         Upon presentation of any Note redeemed in part only, the Company shall
execute and, upon the Company's written direction to the Trustee, the Trustee
shall authenticate and deliver to the holder thereof, at the expense of the
Company, a new Note or Notes, of authorized denominations, in principal amount
equal to the unredeemed portion of the Notes so presented.

          (b) On or before the tenth day after the occurrence of a Fundamental
Change, the Company, or, at its written request (which must be received by the
Trustee at least five (5) Business Days prior to the date the Trustee is
requested to give notice as described below), the Trustee in the name of and at
the expense of the Company, shall mail or cause to be mailed to all holders of
record on the date of the Fundamental Change a notice (the "COMPANY NOTICE") of
the occurrence of such Fundamental Change and of the redemption right at the
option of the holders arising as a result thereof. Such notice shall be mailed
in the manner and with the effect set forth in the first paragraph of Section
3.02. The Company shall also deliver a copy of the Company Notice to the Trustee
at such time as it is mailed to Noteholders. Concurrently with the mailing of
any Company Notice, the Company shall also publish notice of any such redemption
in Bloomberg Business News, DowJones News and Reuters Financial Report in New
York City.

         Each Company Notice shall specify the circumstances constituting the
Fundamental Change, the Repurchase Date, the price at which the Company shall be
obligated to redeem Notes, the latest time (not less than thirty (30) days after
the date of the Company's notice of a Fundamental Change) on the Repurchase Date
by which the holder must exercise the redemption right (the "FUNDAMENTAL CHANGE
EXPIRATION TIME"), that the holder shall have the right to withdraw any Notes
surrendered prior to the Fundamental Change Expiration Time, a description of
the procedure which a Noteholder must follow to exercise such redemption right
and to withdraw any surrendered Notes, the place or places where the holder is
to surrender such holder's Notes, and the amount of interest accrued on each
Note to (but excluding) the Repurchase Date.

         No failure of the Company to give the foregoing notices or to issue any
press release and no defect therein shall limit the Noteholders' redemption
rights or affect the validity of the proceedings for the redemption of the Notes
pursuant to this Section 3.05.

          (c) For a Note to be so redeemed at the option of the holder, the
Company must receive at the office or agency of the Company maintained for that
purpose or, at the option of such holder, the Corporate Trust Office, such Note
with the form entitled "Option to Elect Repayment Upon A Fundamental Change" on
the reverse thereof duly completed, together with such Notes duly endorsed for
transfer, on or before the Fundamental Change Expiration Time. All questions as


                                       22
<PAGE>



to the validity, eligibility (including time of receipt) and acceptance of any
Note for repayment shall be determined by the Company, whose determination shall
be final and binding absent manifest error.

          (d) Following the Fundamental Change Expiration Time, but on or prior
to the Repurchase Date, the Company will deposit with the Trustee or with one or
more paying agents (or, if the Company is acting as its own paying agent, set
aside, segregate and hold in trust as provided in Section 5.04) an amount of
money sufficient to redeem on the Repurchase Date all the Notes to be redeemed
on such date at the appropriate redemption price, together with accrued interest
to (but excluding) the Repurchase Date; PROVIDED that if such payment is made on
the Repurchase Date it must be received by the Trustee or paying agent, as the
case may be, by 10:00 a.m. New York City time, on such date. Payment for Notes
surrendered for redemption (and not withdrawn) prior to the Fundamental Change
Expiration Time will be made promptly (but in no event more than five (5)
Business Days) following the Repurchase Date by mailing checks for the amount
payable to the holders of such Notes entitled thereto as they shall appear on
the registry books of the Company.

          (e) In the case of a reclassification, change, consolidation, merger,
combination, sale or conveyance to which Section 15.06 applies, in which the
Common Stock of the Company is changed or exchanged as a result into the right
to receive stock, securities or other property or assets (including cash), which
includes shares of Common Stock of the Company or shares of common stock of
another Person that are, or upon issuance will be, traded on a United States
national securities exchange or approved for trading on an established automated
over-the-counter trading market in the United States and such shares constitute
at the time such change or exchange becomes effective in excess of 50% of the
aggregate fair market value of such stock, securities or other property or
assets (including cash) (as determined by the Company, which determination shall
be conclusive and binding), then the Person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture (accompanied
by an Opinion of Counsel that such supplemental indenture complies with the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Indenture relating to the right of
holders of the Notes to cause the Company to repurchase the Notes following a
Fundamental Change, including without limitation the applicable provisions of
this Section 3.05 and the definitions of the Common Stock and Fundamental
Change, as appropriate, as determined in good faith by the Company (which
determination shall be conclusive and binding), to make such provisions apply to
such other Person and the common stock of such Person if different from the


                                       23
<PAGE>



Company and Common Stock of the Company (in lieu of the Company and the Common
Stock of the Company).

          (f) The Company will comply with the provisions of Rule 13e-4 and any
other tender offer rules under the Exchange Act to the extent then applicable in
connection with the redemption rights of the holders of Notes in the event of a
Fundamental Change.



                                    ARTICLE 4
                             SUBORDINATION OF NOTES

         SECTION 4.01. AGREEMENT OF SUBORDINATION. The Company covenants and
agrees, and each holder of Notes issued hereunder by its acceptance thereof
likewise covenants and agrees, that all Notes shall be issued subject to the
provisions of this Article 4; and each Person holding any Note, whether upon
original issue or upon transfer, assignment or exchange thereof, accepts and
agrees to be bound by such provisions.

         The payment of the principal of, premium, if any, and interest on and
all other amounts payable under all Notes (including, but not limited to, the
redemption price with respect to the Notes called for redemption in accordance
with Section 3.02 or submitted for redemption in accordance with Section 3.05,
as the case may be, as provided in this Indenture) issued hereunder shall, to
the extent and in the manner hereinafter set forth, be subordinated, junior and
subject in right of payment to the prior payment in full, in cash or other
payment satisfactory to the holders of Senior Indebtedness, of all Senior
Indebtedness, whether outstanding at the date of this Indenture or thereafter
incurred.

         No provision of this Article 4 shall prevent the occurrence of any
Default or Event of Default hereunder.

         SECTION 4.02. PAYMENT TO NOTEHOLDERS. No payment shall be made with
respect to the principal of, premium, if any, or interest on the Notes
(including, but not limited to, the redemption price with respect to the Notes
to be called for redemption in accordance with Section 3.02 or submitted for
redemption in accordance with Section 3.05, as the case may be, as provided in
this Indenture), except payments and distributions made by the Trustee as
permitted by the first or second paragraph of Section 4.05, if:


                                       24
<PAGE>



          (a) a default in the payment of principal, premium, if any, interest,
rent or any other obligations in respect of Senior Indebtedness occurs and is
continuing (or, in the case of Senior Indebtedness for which there is a period
of grace, in the event of such a default that continues beyond the period of
grace, if any, specified in the agreement, instrument, lease or other document
evidencing such Senior Indebtedness) (a "PAYMENT DEFAULT"), unless and until
such Payment Default shall have been cured or waived or shall have ceased to
exist; or

          (b) a default, other than a Payment Default, on any Senior
Indebtedness occurs and is continuing that permits holders of such Senior
Indebtedness to accelerate its maturity and either (i) such default is the
subject of judicial proceedings or (ii) the Trustee receives a notice of the
default (a "PAYMENT BLOCKAGE NOTICE") from a holder of Senior Indebtedness, a
Representative of Senior Indebtedness or the Company (a "NON-PAYMENT DEFAULT").

         If the Trustee receives any Payment Blockage Notice pursuant to clause
(b) above, no subsequent Payment Blockage Notice shall be effective for purposes
of this Section 4.02 unless and until at least 360 days shall have elapsed since
the initial effectiveness of the immediately prior Payment Blockage Notice
unless such Event of Default or such other Events of Default have been cured or
waived for a period of not less than 90 consecutive days. No new Payment
Blockage Period may be commenced by the holder of Senior Indebtedness during any
period of 360 consecutive days unless all Events of Default which triggered the
preceding Payment Blockage period have been cured or waived. No NonPayment
Default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent
Payment Blockage Notice.

         The Company may and shall resume payments on and distributions in
respect of the Notes upon the earlier of:

          (i) in the case of a Payment Default, the date upon which any such
         Payment Default is cured or waived or ceases to exist, or

         (ii) in the case of a Non-Payment Default, the earlier of (A) the date
         upon which such default is cured or waived or ceases to exist or (B)
         179 days after the applicable Payment Blockage Notice is received,

unless this Article 4 otherwise prohibits the payment or distribution at the
time of such payment or distribution.

         Upon any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to


                                       25
<PAGE>



creditors upon any dissolution or winding up or liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due or to become
due upon all Senior Indebtedness shall first be paid in full in cash or other
payment satisfactory to the holders of such Senior Indebtedness, before any
payment is made on account of the principal of, premium, if any, or interest
on and all other amounts payable under the Notes (except payments made
pursuant to Article 13 from monies deposited with the Trustee pursuant
thereto prior to commencement of proceedings for such dissolution, winding
up, liquidation or reorganization and in compliance with this Article 4); and
upon any such dissolution or winding up or liquidation or reorganization of
the Company or bankruptcy, insolvency, receivership or other proceeding, any
payment by the Company, or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the holders
of the Notes or the Trustee would be entitled, except for the provisions of
this Article 4, shall (except as aforesaid) be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the holders of the Notes or by the
Trustee under this Indenture if received by them or it, directly to the
holders of Senior Indebtedness (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders, or as
otherwise required by law or a court order) or their Representative or
Representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing any Senior Indebtedness may have been
issued, as their respective interests may appear as calculated by the
Company, to the extent necessary to pay all Senior Indebtedness in full, in
cash or other payment satisfactory to the holders of such Senior
Indebtedness, after giving effect to any concurrent payment or distribution
in cash or other payment satisfactory to the holders of Senior Indebtedness
to or for the holders of Senior Indebtedness, before any payment or
distribution is made to the holders of the Notes or to the Trustee.

         For purposes of this Article 4, the words, "CASH, PROPERTY OR
SECURITIES" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article 4 with respect
to the Notes to the payment of all Senior Indebtedness which may at the time be
outstanding (as determined by the holders of Senior Indebtedness or the
Representative(s)); PROVIDED that (i) the Senior Indebtedness is assumed by the
new corporation, if any, resulting from any reorganization or readjustment, and
(ii) the rights of the holders of Senior Indebtedness (other than leases which,
in accordance with applicable law and their terms, are not assumed by the
Company or the new corporation, as the case may be) are not, without the consent
of such holders, altered by such reorganization or readjustment. The
consolidation of the


                                       26
<PAGE>



Company with, or the merger of the Company into, another corporation or the
liquidation or dissolution of the Company following the conveyance or transfer
of its property as an entirety, or substantially as an entirety, to another
corporation upon the terms and conditions provided for in Article 12 shall not
be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 4.02 if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article 12.

         In the event of the acceleration of the Notes because of an Event of
Default, no payment or distribution shall be made to the Trustee or any holder
of Notes in respect of the principal of, premium, if any, or interest and all
other amounts payable on the Notes (including, but not limited to, the
redemption price with respect to the Notes called for redemption in accordance
with Section 3.02 or submitted for redemption in accordance with Section 3.05,
as the case may be, as provided in the Indenture), except payments and
distributions made by the Trustee as permitted by the first or second paragraph
of Section 4.05, until all Senior Indebtedness has been paid in full in cash or
other payment satisfactory to the holders of Senior Indebtedness or such
acceleration is rescinded in accordance with the terms of this Indenture, in
which case any payments thereafter made shall only be made if the other
provision of this Article 4 permit such payments. If payment of the Notes is
accelerated because of an Event of Default, the Company shall promptly notify
holders of Senior Indebtedness of the acceleration.

         If, notwithstanding the foregoing provisions, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing provisions in this Section 4.02, shall
be received by the Trustee or the holders of the Notes before all Senior
Indebtedness is paid in full in cash or other payment satisfactory to the
holders of such Senior Indebtedness, such payment or distribution shall be held
in trust for the benefit of and shall be paid over or delivered to the holders
of Senior Indebtedness or their Representative or Representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, for application to the
payment of any Senior Indebtedness remaining unpaid to the extent necessary to
pay all Senior Indebtedness in full in cash or other payment satisfactory to the
holders of such Senior Indebtedness, after giving effect to any concurrent
payment or distribution in cash or other payment satisfactory to the holders of
Senior Indebtedness to or for the holders of such Senior Indebtedness.

         Nothing in this Section 4.02 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 8.06. This Section 4.02 shall be
subject to the further provisions of Section 4.05.


                                       27
<PAGE>


         SECTION 4.03. SUBROGATION OF NOTES. Subject to the payment in full in
cash or other payment satisfactory to the holders of Senior Indebtedness of all
Senior Indebtedness, the rights of the holders of the Notes shall be subrogated
to the extent of the payments or distributions made to the holders of such
Senior Indebtedness pursuant to the provisions of this Article 4 (equally and
ratably with the holders of all Indebtedness of the Company which by its express
terms is subordinated to other Indebtedness of the Company to substantially the
same extent as the Notes are subordinated and is entitled to like rights of
subrogation) to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness until the principal, premium, if any, and
interest on the Notes shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the holders of the
Notes or the Trustee would be entitled except for the provisions of this Article
4, and no payment over pursuant to the provisions of this Article 4, to or for
the benefit of the holders of Senior Indebtedness by holders of the Notes or the
Trustee, shall, as between the Company, its creditors other than holders of
Senior Indebtedness, and the holders of the Notes, be deemed to be a payment by
the Company to or on account of the Senior Indebtedness; and no payments or
distributions of cash, property or securities to or for the benefit of the
holders of the Notes pursuant to the subrogation provisions of this Article 4,
which would otherwise have been paid to the holders of Senior Indebtedness shall
be deemed to be a payment by the Company to or for the account of the Notes. It
is understood that the provisions of this Article 4 are and are intended solely
for the purposes of defining the relative rights of the holders of the Notes, on
the one hand, and the holders of the Senior Indebtedness, on the other hand.

         Nothing contained in this Article 4 or elsewhere in this Indenture or
in the Notes is intended to or shall impair, as among the Company, its creditors
other than the holders of Senior Indebtedness, and the holders of the Notes, the
obligation of the Company, which is absolute and unconditional, to pay to the
holders of the Notes the principal of, premium, if any, and interest on the
Notes as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the holders of
the Notes and creditors of the Company other than the holders of the Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
holder of any Note from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject in each case to the
rights under this Article 4 of the holders of Senior Indebtedness in respect of
cash, property or securities of the Company received upon the exercise of any
such remedy.

         Upon any payment or distribution of assets of the Company referred to
in this Article 4, the Trustee, subject to the provisions of Section 8.01, and
the holders of the Notes shall be entitled to rely upon any order or decree made
by any court of competent jurisdiction in which any bankruptcy, dissolution,
winding up, liquidation or reorganization proceedings of the Company are
pending, or a certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, delivered to
the Trustee or to the holders of the Notes, for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon and all other facts pertinent thereto or to this Article 4.

         SECTION 4.04. AUTHORIZATION TO EFFECT SUBORDINATION. Each holder of a
Note by the holder's acceptance thereof authorizes and directs the Trustee on
the holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article 4 and appoints the
Trustee to act as the holder's attorney-in-fact for any and all such purposes.
If the Trustee does not file a proper proof of claim or proof of debt in the
form required in any proceeding referred to in the third paragraph of Section
7.02 hereof at least thirty (30) days before the expiration of the time to file
such claim, the holders of any Senior Indebtedness or their representatives are
hereby authorized to file an appropriate claim for and on behalf of the holders
of the Notes.

         SECTION 4.05. NOTICE TO TRUSTEE. The Company shall give prompt written
notice in the form of an Officers' Certificate to a Responsible Officer of the
Trustee and to any paying agent of any fact known to the Company which would
prohibit the making of any payment of monies to or by the Trustee or any paying
agent in respect of the Notes pursuant to the provisions of this Article 4.
Notwithstanding the provisions of this Article 4 or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts which would prohibit the making of any payment of monies to or by the
Trustee in respect of the Notes pursuant to the provisions of this Article 4,
unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office from the Company (in the
form of an Officers' Certificate) or a Representative or a holder or holders of
Senior Indebtedness or from any trustee thereof; and before the receipt of any
such written notice, the Trustee, subject to the provisions of Section 8.01,
shall be entitled in all respects to assume that no such facts exist; PROVIDED
that if on a date not less than two Business Days prior to the date upon which
by the terms hereof any such monies may become payable for any purpose
(including, without limitation, the payment of the principal of, or premium, if
any, or interest on any Note) the Trustee shall not have received, with respect
to such monies, the notice provided for in this Section 4.05, then, anything
herein contained to the contrary


                                       29
<PAGE>


notwithstanding, the Trustee shall have full power and authority to apply monies
received to the purpose for which they were received, and shall not be affected
by any notice to the contrary which may be received by it on or after such prior
date.

         Notwithstanding anything in this Article 4 to the contrary, nothing
shall prevent any payment by the Trustee to the Noteholders of monies deposited
with it pursuant to Section 13.01, and any such payment shall not be subject to
the provisions of Section 4.01 or 4.02.

         The Trustee, subject to the provisions of Section 8.01, shall be
entitled to rely on the delivery to it of a written notice by a Representative
or a person representing himself to be a holder of Senior Indebtedness (or a
trustee on behalf of such holder) to establish that such notice has been given
by a Representative or a holder of Senior Indebtedness or a trustee on behalf of
any such holder or holders. The Trustee shall not be required to make any
payment or distribution to or on behalf of a holder of Senior Indebtedness
pursuant to this Article 4 unless it has received satisfactory evidence as to
the amount of Senior Indebtedness held by such person, the extent to which such
person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such person under this Article 4.

         SECTION 4.06. TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS. The Trustee in
its individual capacity shall be entitled to all the rights set forth in this
Article 4 in respect of any Senior Indebtedness at any time held by it, to the
same extent as any other holder of Senior Indebtedness, and nothing in Section
8.13 or elsewhere in this Indenture shall deprive the Trustee of any of its
rights as such holder.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article 4, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Section 8.01, the Trustee shall not be liable to any holder of
Senior Indebtedness (i) for any failure to make any payments or distributions to
such holder or (ii) if it shall pay over or deliver to holders of Notes, the
Company or any other Person money or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article 4 or otherwise.

         SECTION 4.07.  NO IMPAIRMENT OF SUBORDINATION.  No right of any present
or future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good


                                       30
<PAGE>


faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

         SECTION 4.08. CERTAIN CONVERSIONS NOT DEEMED PAYMENT. For the purposes
of this Article 4 only, (1) the issuance and delivery of junior securities upon
conversion of Notes in accordance with Article 15 shall not be deemed to
constitute a payment or distribution on account of the principal of, premium, if
any, or interest on Notes or on account of the purchase or other acquisition of
Notes, and (2) the payment, issuance or delivery of cash (except in satisfaction
of fractional shares pursuant to Section 15.03), property or securities (other
than junior securities) upon conversion of a Note shall be deemed to constitute
payment on account of the principal of, premium, if any, or interest on such
Note. For the purposes of this Section 4.08, the term "JUNIOR SECURITIES" means
(a) shares of any stock of any class of the Company or (b) securities of the
Company that are subordinated in right of payment to all Senior Indebtedness
that may be outstanding at the time of issuance or delivery of such securities
to substantially the same extent as, or to a greater extent than, the Notes are
so subordinated as provided in this Article. Nothing contained in this Article 4
or elsewhere in this Indenture or in the Notes is intended to or shall impair,
as among the Company, its creditors other than holders of Senior Indebtedness
and the holders of the Notes, the right, which is absolute and unconditional, of
the holder of any Note to convert such Note in accordance with Article 15.

         SECTION 4.09. ARTICLE APPLICABLE TO PAYING AGENTS. If at any time any
paying agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the term "TRUSTEE" as used in this Article shall
(unless the context otherwise requires) be construed as extending to and
including such paying agent within its meaning as fully for all intents and
purposes as if such paying agent were named in this Article in addition to or in
place of the Trustee; PROVIDED that the first paragraph of Section 4.05 shall
not apply to the Company or any Affiliate of the Company if it or such Affiliate
acts as paying agent.

         The Trustee shall not be responsible for the actions or inactions of
any other paying agents (including the Company if acting as its own paying
agent) and shall not be deemed to have control of any funds held by such other
paying agents.

         SECTION 4.10.  SENIOR INDEBTEDNESS ENTITLED TO RELY.  The holders of
Senior Indebtedness shall have the right to rely upon and be entitled in full to
the benefits of this Article 4, and no amendment or modification of the
provisions


                                       31
<PAGE>


contained herein shall diminish the rights of such holders unless such holders
shall have agreed in writing thereto.

         SECTION 4.11. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT. Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee and the Noteholders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Noteholders, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.



                                    ARTICLE 5
                       PARTICULAR COVENANTS OF THE COMPANY

         SECTION 5.01. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company
covenants and agrees that it will duly and punctually pay or cause to be paid
the principal of and premium, if any (including upon redemption pursuant to
Article 3), and interest on each of the Notes at the places, at the respective
times and in the manner provided herein and in the Notes. Each installment of
interest on the Notes due on any semi-annual interest payment date may be paid
either (i) by check mailed to the address of the Person entitled thereto as it
appears in the Note register; or (ii) by transfer to an account maintained by
such Person located in the United States if such Person has notified the Company
of the details of such account at least seven (7) days prior to a scheduled
interest payment date; PROVIDED that payments to the Depositary will be made by
wire transfer of immediately available funds to the account of the Depositary or
its nominee.

         SECTION 5.02. MAINTENANCE OF OFFICE OR AGENCY. The Company will
maintain in The Borough of Manhattan, The City of New York, an office or agency
where the Notes may be surrendered for registration of transfer or exchange or
for presentation for payment or for conversion or redemption and where notices
and demands to or upon the Company in respect of the Notes and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or


                                       32
<PAGE>


agency not designated or appointed by the Trustee. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office. The
Company hereby appoints the Trustee at its [Corporate Trust Office] its agent to
receive all such presentations, surrenders, notices and demands.

         The Company may also from time to time designate co-registrars and one
or more other offices or agencies where the Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

         The Company hereby initially designates the Trustee as paying agent,
Note registrar, Custodian and conversion agent.

         So long as the Trustee is the Note registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 8.10(a) and the
third paragraph of Section 8.11. If co-registrars have been appointed in
accordance with this Section, the Trustee shall mail such notices only to the
Company and the holders of Notes it can identify from its records.

          SECTION 5.03. APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 8.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

          SECTION 5.04. PROVISIONS AS TO PAYING AGENT.

          (a) If the Company shall appoint a paying agent other than the
Trustee, or if the Trustee shall appoint such a paying agent, it will cause such
paying agent to execute and deliver to the Trustee an instrument in which such
agent shall agree with the Trustee, subject to the provisions of this
Section 5.04:

              (i) that it will hold all sums held by it as such agent for the
         payment of the principal of and premium, if any, or interest on the
         Notes (whether such sums have been paid to it by the Company or by any
         other obligor on the Notes) in trust for the benefit of the holders of
         the Notes;

              (ii) that it will give the Trustee notice of any failure by the
         Company (or by any other obligor on the Notes) to make any payment of


                                       33
<PAGE>


         the principal of and premium, if any, or interest on the Notes when
         the same shall be due and payable; and

              (iii) that at any time during the continuance of an Event of
         Default, upon request of the Trustee, it will forthwith pay to the
         Trustee all sums so held in trust.

         The Company shall, on or before each due date of the principal of,
premium, if any, or interest on the Notes, deposit with the paying agent a sum
sufficient (in immediately available funds) to pay such principal, premium, if
any, or interest, and (unless such paying agent is the Trustee) the Company will
promptly notify the Trustee of any failure to take such action; PROVIDED that if
such deposit is made on the due date, such deposit shall be received by the
paying agent by 10:00 a.m. New York City time, on such date.

          (b) If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of, premium, if any, or interest on the
Notes, set aside, segregate and hold in trust for the benefit of the holders of
the Notes a sum sufficient to pay such principal, premium, if any, or interest
so becoming due and will notify the Trustee of any failure to take such action
and of any failure by the Company (or any other obligor under the Notes) to make
any payment of the principal of, premium, if any, or interest on the Notes when
the same shall become due and payable.

          (c) Anything in this Section 5.04 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid to
the Trustee all sums held in trust by the Company or any paying agent hereunder
as required by this Section 5.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent
to the Trustee, the Company or such paying agent shall be released from all
further liability with respect to such sums.

          (d) Anything in this Section 5.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 5.04 is subject to
Sections 13.03 and 13.04.

          SECTION 5.05. EXISTENCE. Subject to Article 12, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence and rights (charter and statutory); PROVIDED that the
Company shall not be required to preserve any such right if the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the


                                       34
<PAGE>


Company and that the loss thereof is not disadvantageous in any material respect
to the holders.

          SECTION 5.06. MAINTENANCE OF PROPERTIES. The Company will cause all
properties used or useful in the conduct of its business or the business of any
Significant Subsidiary to be maintained and kept in good condition, repair and
working order except for ordinary wear and tear and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly conducted at all times; PROVIDED that nothing in this
Section shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business or the business of any
Significant Subsidiary and not disadvantageous in any material respect to the
holders.

          SECTION 5.07. PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay
or discharge, or cause to be paid or discharged, before the same may become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Significant Subsidiary or upon the income,
profits or property of the Company or any Significant Subsidiary, (ii) all
claims for labor, materials and supplies which, if unpaid, might by law become a
lien or charge upon the property of the Company or any Significant Subsidiary
and (iii) all stamps and other duties, if any, which may be imposed by the
United States or any political subdivision thereof or therein in connection with
the issuance, transfer, exchange or conversion of any Notes or with respect to
this Indenture (except to the extent this Indenture imposes liability therefor
on a holder of Notes); PROVIDED that, in the case of clauses (i) and (ii), the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim (A) if the failure to do so
will not, in the aggregate, have a material adverse impact on the Company, or
(B) if the amount, applicability or validity is being contested in good faith by
appropriate proceedings.

          SECTION 5.08. STAY, EXTENSION AND USURY LAWS. The Company covenants
(to the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law which would prohibit or
forgive the Company from paying all or any portion of the principal of, premium,
if any, or interest on the Notes as contemplated herein, wherever enacted, now
or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture, and the Company (to the extent it may lawfully do
so) hereby


                                       35
<PAGE>



expressly waives all benefit or advantage of any such law, and covenants that it
will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

          SECTION 5.09. COMPLIANCE CERTIFICATE. The Company shall deliver to the
Trustee, within one hundred twenty (120) days after the end of each fiscal year
of the Company, a certificate signed by either the principal executive officer,
principal financial officer or principal accounting officer of the Company,
stating whether or not to the best knowledge of the signer thereof the Company
is in default in the performance and observance of any of the terms, provisions
and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company shall be in
default, specifying all such defaults and the nature and status thereof of which
the signer may have knowledge.

         The Company will deliver to the Trustee, forthwith upon becoming aware
of any default in the performance or observance of any covenant, agreement or
condition contained in this Indenture, or any Event of Default, an Officers'
Certificate specifying with particularity such default or Event of Default and
further stating what action the Company has taken, is taking or proposes to take
with respect thereto.

         Any notice required to be given under this Section 5.09 shall be
delivered to the Trustee at its Corporate Trust Office.

that it will furnish or cause to be furnished to the Trustee, semiannually, not
more than fifteen (15) days after each February 1 and August 1 in each year

to enable it to timely provide any notice to be provided by it hereunder), a
list in such form as the Trustee may reasonably require of the names and
addresses of the holders of Notes as of a date not more than fifteen (15) days
(or such other date as the Trustee may reasonably request in order to so provide
any such notices) prior to the time such information is furnished, except that
no such list need be furnished


                                       36
<PAGE>


by the Company to the Trustee so long as the Trustee is acting as the sole Note
registrar.

          SECTION 6.02. PRESERVATION AND DISCLOSURE OF LISTS.

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the holders of
Notes contained in the most recent list furnished to it as provided in
Section 6.01 or maintained by the Trustee in its capacity as Note registrar or
co-registrar in respect of the Notes, if so acting. The Trustee may destroy any
list furnished to it as provided in Section 6.01 upon receipt of a new list so
furnished.

          (b) The rights of Noteholders to communicate with other holders of
Notes with respect to their rights under this Indenture or under the Notes, and
the corresponding rights and duties of the Trustee, shall be as provided by the
Trust Indenture Act.

          (c) Every Noteholder, by receiving and holding the same, agrees with

Trust Indenture Act.

          SECTION 6.03. REPORTS BY TRUSTEE.

          (a) Within sixty (60) days after January 31 of each year commencing

          (b) A copy of such report shall, at the time of such transmission to

same is so required to be filed with the Commission. Delivery of such reports,
information and documents to the Trustee is for informational purposes only and
the Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).



                                    ARTICLE 7

Company as contemplated by Section 12.02 of this Indenture will not be an Event
of Default; or

          (e) an involuntary case or other proceeding shall be commenced against
the Company seeking liquidation, reorganization or other relief with respect to
it or its debts under any bankruptcy, insolvency or other similar law now or
hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of it or any substantial part of
the property of the Company, and such involuntary case or other proceeding shall
remain undismissed and unstayed for a period of ninety (90) consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 7.01(d) or (e) with respect to the Company), unless the principal of
all of the Notes shall have already become due and payable, either the Trustee
or the holders of not less than twenty-five percent (25%) in aggregate principal
amount of the Notes then outstanding hereunder determined in accordance with
Section 9.04, by notice in writing to the Company (and to the Trustee if given
by Noteholders), may declare the principal of and premium, if any, on all the
Notes and the interest accrued thereon to be due and payable immediately, and
upon any such declaration the same shall become and shall be immediately due and
payable, anything in this Indenture or in the Notes contained to the contrary
notwithstanding. If an Event of Default specified in Section 7.01(d) or (e) with
respect to the Company occurs, the principal of all the Notes and the interest
accrued thereon shall be immediately and automatically due and payable without
necessity of further action. This provision, however, is subject to the
conditions that if, at any time after the principal of the Notes shall have been
so declared due and payable, and before any judgment or decree for the payment
of the monies due shall have been obtained or entered as hereinafter provided,
the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
all matured installments of interest upon all Notes and the principal of and
premium, if any, on any and all Notes which shall have become due otherwise than
by acceleration (with interest on overdue installments of interest (to the
extent that payment of such interest is enforceable under applicable law) and on
such principal and premium, if any, at the rate borne by the Notes, to the date
of such payment or


                                       39

deposit) and amounts due to the Trustee pursuant to Section 8.06, and if any and
all defaults under this Indenture, other than the nonpayment of principal of and
premium, if any, and accrued interest on Notes which shall have become due by
acceleration, shall have been cured or waived pursuant to Section 7.07--then and
in every such case the holders of a majority in aggregate principal amount of
the Notes then outstanding, by written notice to the Company and to the Trustee,
may waive all defaults or Events of Default and rescind and annul such
declaration and its consequences; but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent default or Event of Default, or
shall impair any right consequent on any such subsequent Default or Event of
Default. The Company shall notify a Responsible Officer of the Trustee, promptly
upon becoming aware thereof, of any Event of Default.

         In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such waiver or rescission and annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the holders of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the holders of Notes, and the Trustee shall
continue as though no such proceeding had been taken.

          SECTION 7.02. PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR. The Company
covenants that (a) in case default shall be made in the payment of any
installment of interest upon any of the Notes as and when the same shall become
due and payable, and such default shall have continued for a period of thirty
(30) days, or (b) in case default shall be made in the payment of the principal
of or premium, if any, on any of the Notes as and when the same shall have
become due and payable, whether at maturity of the Notes or in connection with
any redemption, by or under this Indenture or otherwise--then, upon demand of
the Trustee, the Company will pay to the Trustee, for the benefit of the holders
of the Notes, the whole amount that then shall have become due and payable on
all such Notes for principal and premium, if any, or interest, as the case may
be, with interest upon the overdue principal and premium, if any, and (to the
extent that payment of such interest is enforceable under applicable law) upon
the overdue installments of interest at the rate borne by the Notes; and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including reasonable compensation to the Trustee,
its agents, attorneys and counsel, and any expenses or liabilities reasonably
incurred by the Trustee hereunder other than through its negligence or bad
faith. Until such demand by the Trustee, the Company may pay the principal of
and premium, if any, and interest on the Notes to the registered holders,
whether or not the Notes are overdue.


                                       40
<PAGE>


         In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes wherever situated the monies adjudged or decreed
to be payable.

         In the case there shall be pending proceedings for the bankruptcy or
for the reorganization of the Company or any other obligor on the Notes under
Title 11 of the United States Code, or any other applicable law, or in case a
receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken
possession of the Company or such other obligor, the property of the Company or
such other obligor, or in the case of any other judicial proceedings relative to
the Company or such other obligor upon the Notes, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 7.02,
shall be entitled and empowered, by intervention in such proceedings or
otherwise, to file and prove a claim or claims for the whole amount of
principal, premium, if any, and interest owing and unpaid in respect of the
Notes, and, in case of any judicial proceedings, to file such proofs of claim
and other papers or documents as may be necessary or advisable in order to have
the claims of the Trustee and of the Noteholders allowed in such judicial
proceedings relative to the Company or any other obligor on the Notes, its or
their creditors, or its or their property, and to collect and receive any monies
or other property payable or deliverable on any such claims, and to distribute
the same after the deduction of any amounts due the Trustee under Section 8.06;
and any receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, custodian or similar official is hereby authorized by each of the
Noteholders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to the
Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, disbursements and advances, (including reasonable
counsel fees incurred by it up to the date of such distribution). To the extent
that such payment of reasonable compensation, expenses, advances and
disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property
which the holders of the Notes may be entitled to receive in


                                       41
<PAGE>



such proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

         All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes, or the production thereof at any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the holders of the Notes.

         In any proceedings brought by the Trustee (and in any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Notes, and it shall not be necessary to make any holders of the Notes
parties to any such proceedings.

         SECTION 7.03. APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies
collected by the Trustee pursuant to this Article 7 shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:

                  FIRST:  To the payment of all amounts due the Trustee under
         Section 8.06;

                  SECOND: Subject to the provisions of Article 4, in case the
         principal of the outstanding Notes shall not have become due and be
         unpaid, to the payment of interest on the Notes in default in the order
         of the maturity of the installments of such interest, with interest (to
         the extent that such interest has been collected by the Trustee) upon
         the overdue installments of interest at the rate borne by the Notes,
         such payments to be made ratably to the Persons entitled thereto;

                  THIRD: Subject to the provisions of Article 4, in case the
         principal of the outstanding Notes shall have become due, by
         declaration or otherwise, and be unpaid to the payment of the whole
         amount then owing and unpaid upon the Notes for principal and premium,
         if any, and interest, with interest on the overdue principal and
         premium, if any (to the extent that such interest has been collected by
         the Trustee), and in case such monies shall be insufficient to pay in
         full the whole amounts so due and unpaid upon the Notes, then to the
         payment of such principal and


                                       42
<PAGE>


         premium, if any, and interest without preference or priority of
         principal and premium, if any, over interest, or of interest over
         principal and premium, if any, or of any installment of interest over
         any other installment of interest, or of any Note over any other Note,
         ratably to the aggregate of such principal and premium, if any, and
         accrued and unpaid interest; and

                  FOURTH:  Subject to the provisions of Article 4, to the
         payment of the remainder, if any, to the Company or any other Person
         lawfully entitled thereto.

          SECTION 7.04. PROCEEDINGS BY NOTEHOLDER. No holder of any Note shall
have any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture, or for the appointment of a receiver, trustee,
liquidator, custodian or other similar official, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also the holders of at least a majority in aggregate
principal amount of the Notes then outstanding shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such indemnity as it may
reasonably require against the costs, expenses and liabilities to be incurred
therein or thereby, and the Trustee for sixty (60) days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding and no direction inconsistent with
such written request shall have been given to the Trustee pursuant to Section
7.07; it being understood and intended, and being expressly covenanted by the
taker and holder of every Note with every other taker and holder and the
Trustee, that no one or more holders of Notes shall have any right in any manner
whatever by virtue of or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other holder of Notes, or to
obtain or seek to obtain priority over or preference to any other such holder,
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all holders of Notes
(except as otherwise provided herein). For the protection and enforcement of
this Section 7.04, each and every Noteholder and the Trustee shall be entitled
to such relief as can be given either at law or in equity.

         Notwithstanding any other provision of this Indenture and any provision
of any Note, the right of any holder of any Note to receive payment of the
principal of and premium, if any (including upon redemption pursuant to Article
3), and accrued interest on such Note, on or after the respective due dates
expressed in such Note or in the event of redemption, or to institute suit for
the


                                       43
<PAGE>



enforcement of any such payment on or after such respective dates against the
Company shall not be impaired or affected without the consent of such holder.

         Anything in this Indenture or the Notes to the contrary
notwithstanding, the holder of any Note, without the consent of either the
Trustee or the holder of any other Note, on its own behalf and for its own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, its rights of conversion as provided herein.

          SECTION 7.05. PROCEEDINGS BY TRUSTEE. In case of an Event of Default
the Trustee may in its discretion proceed to protect and enforce the rights
vested in it by this Indenture by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any of such rights,
either by suit in equity or by action at law or by proceeding in bankruptcy or
otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted in
this Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.

          SECTION 7.06. REMEDIES CUMULATIVE AND CONTINUING. Except as provided
in Section 2.06, all powers and remedies given by this Article 7 to the Trustee
or to the Noteholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the holders of the Notes, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture, and no delay or omission of the Trustee
or of any holder of any of the Notes to exercise any right or power accruing
upon any default or Event of Default occurring and continuing as aforesaid shall
impair any such right or power, or shall be construed to be a waiver of any such
default or any acquiescence therein; and, subject to the provisions of Section
7.04, every power and remedy given by this Article 7 or by law to the Trustee or
to the Noteholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Noteholders.

          SECTION 7.07. DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY
MAJORITY OF NOTEHOLDERS. The holders of a majority in aggregate principal amount
of the Notes at the time outstanding determined in accordance with Section 9.04
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee; PROVIDED that (a) such direction shall not be in
conflict with any rule of law or with this Indenture, (b) the Trustee may take
any other action deemed proper by the Trustee which is not inconsistent with
such direction and (c) the Trustee may decline to take any action that would
benefit


                                       44
<PAGE>


some Noteholder to the detriment of other Noteholders. The holders of a majority
in aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 9.04 may on behalf of the holders of all of the Notes
waive any past default or Event of Default hereunder and its consequences except
(i) a default in the payment of interest or premium, if any, on, or the
principal of, the Notes, (ii) a failure by the Company to convert any Notes into
Common Stock, (iii) a default in the payment of redemption price pursuant to
Article 3 or (iv) a default in respect of a covenant or provisions hereof which
under Article 11 cannot be modified or amended without the consent of the
holders of all Notes then outstanding. Upon any such waiver, the Company, the
Trustee and the holders of the Notes shall be restored to their former positions
and rights hereunder; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon. Whenever any
default or Event of Default hereunder shall have been waived as permitted by
this Section 7.07, said default or Event of Default shall for all purposes of
the Notes and this Indenture be deemed to have been cured and to be not
continuing; but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon.

          SECTION 7.08. NOTICE OF DEFAULTS. The Trustee shall, within ninety
(90) days after a Responsible Officer of the Trustee has knowledge of the
occurrence of a default, mail to all Noteholders, as the names and addresses of
such holders appear upon the Note register, notice of all defaults known to a
Responsible Officer, unless such defaults shall have been cured or waived before
the giving of such notice; and PROVIDED that, except in the case of default in
the payment of the principal of, or premium, if any, or interest on any of the
Notes, the Trustee shall be protected in withholding such notice if and so long
as a trust committee of directors and/or Responsible Officers of the Trustee in
good faith determine that the withholding of such notice is in the interests of
the Noteholders.

          SECTION 7.09. UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each holder of any Note by his acceptance thereof shall be deemed to
have agreed, that any court may, in its discretion, require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; PROVIDED that the provisions of this Section 7.09 (to the extent
permitted by law) shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Noteholder, or group of Noteholders, holding in the
aggregate more than 25 percent in principal amount of the Notes at the time
outstanding determined in accordance with


                                       45
<PAGE>


Section 9.04, or to any suit instituted by any Noteholder for the enforcement of
the payment of the principal of or premium, if any, or interest on any Note on
or after the due date expressed in such Note or to any suit for the enforcement
of the right to convert any Note in accordance with the provisions of
Article 15.



                                    ARTICLE 8
                             CONCERNING THE TRUSTEE

          SECTION 8.01. DUTIES AND RESPONSIBILITIES OF TRUSTEE. The Trustee,
prior to the occurrence of an Event of Default and after the curing of all
Events of Default which may have occurred, undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture. In case an
Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

         No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, its own willful misconduct, its own recklessness or its own bad faith,
except that

          (a) prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default which may have occurred:

               (i) the duties and obligations of the Trustee shall be determined
          solely by the express provisions of this Indenture and the Trust
          Indenture Act, and the Trustee shall not be liable except for the
          performance of such duties and obligations as are specifically set
          forth in this Indenture and no implied covenants or obligations shall
          be read into this Indenture and the Trust Indenture Act against the
          Trustee; and

               (ii) in the absence of bad faith and willful misconduct on the
          part of the Trustee, the Trustee may conclusively rely, as to the
          truth of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Trustee
          and conforming to the requirements of this Indenture; but, in the case
          of any such certificates or opinions which by any provisions hereof
          are specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Indenture;


                                       46
<PAGE>



          (b) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer or Officers of the Trustee, unless the
Trustee was negligent in ascertaining the pertinent facts;

          (c) the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the written
direction of the holders of not less than a majority in principal amount of the
Notes at the time outstanding determined as provided in Section 9.04 relating to
the time, method and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any trust or power conferred upon the Trustee,
under this Indenture;

          (d) whether or not therein provided, every provision of this Indenture
relating to the conduct or affecting the liability of, or affording protection
to, the Trustee shall be subject to the provisions of this Section;

          (e) the Trustee, as trustee, shall not be liable in respect of any
payment (as to the correctness of amount, entitlement to receive or any other
matters relating to payment) or notice effected by the Company or any paying
agent or any records maintained by any co-registrar with respect to the Notes;
and

          (f) if any party fails to deliver a notice relating to an event the
fact of which, pursuant to this Indenture, requires notice to be sent to the
Trustee, the Trustee may conclusively rely on its failure to receive such notice
as reason to act as if no such event occurred.

         None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

          SECTION 8.02. RELIANCE ON DOCUMENTS, OPINIONS, ETC. Except as
otherwise provided in Section 8.01:

          (a) the Trustee may conclusively rely and shall be protected in acting
upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, bond, debenture, note, coupon or other paper or
document believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties;


                                       47
<PAGE>



          (b) any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the Secretary or an Assistant Secretary of the Company;

          (c) the Trustee may consult with counsel of its selection and any
advice of counsel or Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken or omitted by it hereunder in good
faith and in accordance with such advice of counsel or Opinion of Counsel;

          (d) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Noteholders pursuant to the provisions of this
Indenture, unless such Noteholders shall have offered to the Trustee security or
indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities which may be incurred therein or thereby;

          (e) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture or
other paper or document, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company personally or by agent or attorney; and

          (f) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed by it with due care
hereunder.

          SECTION 8.03. NO RESPONSIBILITY FOR RECITALS, ETC. The recitals
contained herein and in the Notes (except in the Trustee's certificate of
authentication or with respect to the Trustee's status) shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Notes. The Trustee shall not be
accountable for the use or application by the Company of any Notes or the
proceeds of any Notes authenticated and delivered by the Trustee in conformity
with the provisions of this Indenture.


                                       48
<PAGE>


          SECTION 8.04. TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR REGISTRAR
MAY OWN NOTES. The Trustee, any paying agent, any conversion agent or Note
registrar, in its individual or any other capacity, may become the owner or
pledgee of Notes with the same rights it would have if it were not Trustee,
paying agent, conversion agent or Note registrar.

          SECTION 8.05. MONIES TO BE HELD IN TRUST. Subject to the provisions of
Section 13.04 and Section 4.02, all monies received by the Trustee shall, until
used or applied as herein provided, be held in trust for the purposes for which
they were received. Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as may be agreed from time to time by the Company and the Trustee.

          SECTION 8.06. COMPENSATION AND EXPENSES OF TRUSTEE. The Company
covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, reasonable compensation for all services rendered by it
hereunder in any capacity (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) as mutually agreed
to in writing between the Company and the Trustee, and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all Persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence, willful misconduct, recklessness or
bad faith. The Company also covenants to indemnify the Trustee (or any officer,
director or employee of the Trustee) in any capacity under this Indenture and
its agents and any authenticating agent for, and to hold them harmless against,
any loss, liability or expense incurred without negligence, willful misconduct,
recklessness, or bad faith on the part of the Trustee or such officers,
directors, employees and agent or authenticating agent, as the case may be, and
arising out of or in connection with the acceptance or administration of this
trust or in any other capacity hereunder, including the reasonable costs and
expenses of defending themselves against any claim of liability in the premises.
The obligations of the Company under this Section 8.06 to compensate or
indemnify the Trustee and to pay or reimburse the Trustee for reasonable
expenses, disbursements and advances shall be secured by a lien prior to that of
the Notes upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular Notes.
The obligation of the Company under this Section shall survive the satisfaction
and discharge of this Indenture.

         When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in
Section 7.01(d) or (e) with respect to the Company occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws.

          SECTION 8.07. OFFICERS' CERTIFICATE AS EVIDENCE. Except as otherwise
provided in Section 8.01, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence, willful misconduct, recklessness,
or bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee.

          SECTION 8.08. CONFLICTING INTERESTS OF TRUSTEE. If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such conflict or resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust
Indenture Act and this Indenture.

          SECTION 8.09. ELIGIBILITY OF TRUSTEE. There shall at all times be a
Trustee hereunder which shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined capital and surplus of at least
$50,000,000 (or if such Person is a member of a bank holding company system, its
bank holding company shall have a combined capital and surplus of at least
$50,000,000). If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of any supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

          SECTION 8.10. RESIGNATION OR REMOVAL OF TRUSTEE.

          (a) The Trustee may at any time resign by giving written notice of
such resignation to the Company and to the holders of Notes. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors,
one copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment sixty (60) days after the mailing of
such notice of


                                       50
<PAGE>


resignation to the Noteholders, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee, or any
Noteholder who has been a bona fide holder of a Note or Notes for at least six
(6) months may, subject to the provisions of Section 7.09, on behalf of himself
and all others similarly situated, petition any such court for the appointment
of a successor trustee. Such court may thereupon, after such notice, if any, as
it may deem proper and prescribe, appoint a successor trustee.

          (b) In case at any time any of the following shall occur:

               (i) the Trustee shall fail to comply with Section 8.08 after
          written request therefor by the Company or by any Noteholder who has
          been a bona fide holder of a Note or Notes for at least six (6)
          months; or

               (ii) the Trustee shall cease to be eligible in accordance with
          the provisions of Section 8.09 and shall fail to resign after written
          request therefor by the Company or by any such Noteholder; or

               (iii) the Trustee shall become incapable of acting, or shall be
          adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
          its property shall be appointed, or any public officer shall take
          charge or control of the Trustee or of its property or affairs for the
          purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee, or, subject to the
provisions of Section 7.09, any Noteholder who has been a bona fide holder of a
Note or Notes for at least six (6) months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor trustee; PROVIDED that
if no successor Trustee shall have been appointed and have accepted appointment
sixty (60) days after either the Company or the Noteholders has removed the
Trustee, the Trustee so removed may petition any court of competent jurisdiction
for an appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

          (c) The holders of a majority in aggregate principal amount of the
Notes at the time outstanding may at any time remove the Trustee and nominate a
successor trustee which shall be deemed appointed as successor trustee unless
within ten (10) days after notice to the Company of such nomination the Company


                                       51
<PAGE>


objects thereto, in which case the Trustee so removed or any Noteholder, upon
the terms and conditions and otherwise as in Section 8.10(a) provided, may
petition any court of competent jurisdiction for an appointment of a successor
trustee.

          (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.11.

               SECTION 8.11. ACCEPTANCE BY SUCCESSOR TRUSTEE. Any successor
trustee appointed as provided in Section 8.10 shall execute, acknowledge and
deliver to the Company and to its predecessor trustee an instrument accepting
such appointment hereunder, and, if requested by the Company a supplemental
indenture under which it assumes the rights, duties and obligations of the
Trustee hereunder and thereupon the resignation or removal of the predecessor
trustee shall become effective and such successor trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, duties
and obligations of its predecessor hereunder, with like effect as if originally
named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amounts then due it pursuant to the provisions of Section 8.06,
execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers. Any trustee ceasing to act shall, nevertheless,
retain a lien upon all property and funds held or collected by such trustee as
such, except for funds held in trust for the benefit of holders of particular
Notes, to secure any amounts then due it pursuant to the provisions of Section
8.06.

         No successor trustee shall accept appointment as provided in this
Section 8.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 8.08 and be eligible under the
provisions of Section 8.09.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 8.11, the Company (or the former trustee, at the written direction
of the Company) shall mail or cause to be mailed notice of the succession of
such trustee hereunder and of the address of the new corporate trust office to
the holders of Notes at their addresses as they shall appear on the Note
register. If the Company fails to mail such notice within ten (10) days after
acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be mailed at the expense of the Company.


                                       52
<PAGE>


          SECTION 8.12. SUCCESSION BY MERGER, ETC. Any corporation into which
the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee (including any
trust created by this Indenture), shall be the successor to the Trustee
hereunder without the execution or filing of any paper or any further act on the
part of any of the parties hereto, PROVIDED that in the case of any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee such corporation shall be and shall continue to be qualified under the
provisions of Section 8.08 and eligible under the provisions of Section 8.09.

         In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor trustee or authenticating agent appointed
by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or an authenticating agent appointed by such successor
trustee may authenticate such Notes either in the name of any predecessor
trustee hereunder or in the name of the successor trustee; and in all such cases
such certificate of authentication shall have the full force which it is
provided in the Notes or in this Indenture; PROVIDED that the right to adopt the
certificate of authentication of any predecessor Trustee or authenticate Notes
in the name of any predecessor Trustee shall apply only to its successor or
successors by merger, conversion or consolidation.

          SECTION 8.13. PREFERENTIAL COLLECTION OF CLAIMS. If and when the
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Notes), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of the claims against the Company (or any
such other obligor).

          SECTION 8.14. TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE COMPANY.
Any application by the Trustee for written instructions from the Company (other
than with regard to any action proposed to be taken or omitted to be taken by
the Trustee that affects the rights of the holders of the Notes or holders of
Senior Indebtedness under this Indenture, including, without limitation, under
Article 4 hereof) may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under this Indenture and
the date on and/or after which such action shall be taken or such omission shall
be effective. The Trustee shall not be liable for any action taken by, or
omission of, the Trustee in accordance with a proposal included in such
application on or after the date


                                       53
<PAGE>



specified in such application (which date shall not be less than five (5)
Business Days after the date any officer of the Company actually receives such
application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.



                                    ARTICLE 9
                           CONCERNING THE NOTEHOLDERS

          SECTION 9.01. ACTION BY NOTEHOLDERS. Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by Noteholders
in Person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article 10, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders. Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, the Company or the Trustee may fix in
advance of such solicitation, a date as the record date for determining holders
entitled to take such action. The record date shall be not more than fifteen
(15) days prior to the date of commencement of solicitation of such action.

          SECTION 9.02. PROOF OF EXECUTION BY NOTEHOLDERS. Subject to the
provisions of Sections 8.01, 8.02 and 10.05, proof of the execution of any
instrument by a Noteholder or its agent or proxy shall be sufficient if made in
accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be reasonably satisfactory to the
Trustee. The holding of Notes shall be proved by the registry of such Notes or
by a certificate of the Note registrar.

         The record of any Noteholders' meeting shall be proved in the manner
provided in Section 10.06.

          SECTION 9.03. WHO ARE DEEMED ABSOLUTE OWNERS. The Company, the
Trustee, any paying agent, any conversion agent and any Note registrar may deem


                                       54
<PAGE>


the Person in whose name such Note shall be registered upon the Note register to
be, and may treat it as, the absolute owner of such Note (whether or not such
Note shall be overdue and notwithstanding any notation of ownership or other
writing thereon) for the purpose of receiving payment of or on account of the
principal of, premium, if any, and interest on such Note, for conversion of such
Note and for all other purposes; and neither the Company nor the Trustee nor any
paying agent nor any conversion agent nor any Note registrar shall be affected
by any notice to the contrary. All such payments so made to any holder for the
time being, or upon his order, shall be valid, and, to the extent of the sum or
sums so paid, effectual to satisfy and discharge the liability for monies
payable upon any such Note.

          SECTION 9.04. COMPANY-OWNED NOTES DISREGARDED. In determining whether
the holders of the requisite aggregate principal amount of Notes have concurred
in any direction, consent, waiver or other action under this Indenture, Notes
which are owned by the Company or any other obligor on the Notes or any
Affiliate of the Company or any other obligor on the Notes shall be disregarded
and deemed not to be outstanding for the purpose of any such determination;
PROVIDED that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, consent, waiver or other action only
Notes which a Responsible Officer knows are so owned shall be so disregarded.
Notes so owned which have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 9.04 if the pledgee shall establish
to the satisfaction of the Trustee the pledgee's right to vote such Notes and
that the pledgee is not the Company, any other obligor on the Notes or any
Affiliate of the Company or any such other obligor. In the case of a dispute as
to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee. Upon request of the Trustee, the
Company shall furnish to the Trustee promptly an Officers' Certificate listing
and identifying all Notes, if any, known by the Company to be owned or held by
or for the account of any of the above described Persons; and, subject to
Section 8.01, the Trustee shall be entitled to accept such Officers' Certificate
as conclusive evidence of the facts therein set forth and of the fact that all
Notes not listed therein are outstanding for the purpose of any such
determination.

          SECTION 9.05. REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND. At any
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 9.01, of the taking of any action by the holders of the percentage in
aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any holder of a Note which is shown by the evidence
to be included in the Notes the holders of which have consented to such action
may, by filing written notice with the Trustee at its Corporate Trust Office and
upon proof of holding as provided in Section 9.02, revoke such action so far as
concerns such


                                       55
<PAGE>


Note. Except as aforesaid, any such action taken by the holder of any Note shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon
such Note or any Note issued in exchange or substitution therefor.



                                   ARTICLE 10

<PAGE>



         Any meeting of Noteholders shall be valid without notice if the holders
of all Notes then outstanding are present in person or by proxy or if notice is
waived before or after the meeting by the holders of all Notes outstanding, and
if the Company and the Trustee are either present by duly authorized
representatives or have, before or after the meeting, waived notice.

          SECTION 10.03. CALL OF MEETINGS BY COMPANY OR NOTEHOLDERS. In case at
any time the Company, pursuant to a resolution of its Board of Directors, or the
holders of at least ten percent (10%) in aggregate principal amount of the Notes
then outstanding, shall have requested the Trustee to call a meeting of
Noteholders, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed the
notice of such meeting within twenty (20) days after receipt of such request,
then the Company or such Noteholders may determine the time and the place for
such meeting and may call such meeting to take any action authorized in Section
10.01, by mailing notice thereof as provided in Section 10.02.

          SECTION 10.04. QUALIFICATIONS FOR VOTING. To be entitled to vote at
any meeting of Noteholders a Person shall be a (a) holder of one or more Notes
on the record date pertaining to such meeting or (b) Person appointed by an

concerning the conduct of the meeting as it shall think fit.

         The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Noteholders as provided in Section 10.03, in which case the
Company or the Noteholders calling the meeting, as the case may be, shall in

secretary of the meeting shall be elected by vote of the holders of a majority
in principal amount of the Notes represented at the meeting and entitled to vote

         Subject to the provisions of Section 9.04, at any meeting each
Noteholder or proxyholder shall be entitled to one vote for each $1,000
principal amount of Notes held or represented by him; PROVIDED that no vote

outstanding and ruled by the chairman of the meeting to be not outstanding. The
chairman of the meeting shall have no right to vote other than by virtue of
Notes held by him or instruments in writing as aforesaid duly designating him as
the proxy to vote on behalf of other Noteholders. Any meeting of Noteholders
duly called pursuant to the provisions of Section 10.02 or 10.03 may be
adjourned from time to time by the holders of a majority of the aggregate

one or more Persons having knowledge of the facts setting forth a copy of the

signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one of the duplicates shall be delivered to the Company and the

                             SUPPLEMENTAL INDENTURES

          SECTION 11.01. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF NOTEHOLDERS.
The Company, when authorized by the resolutions of the Board of Directors, and
the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto for one or more of the following purposes:

          (a) to make provision with respect to the conversion rights of the
holders of Notes pursuant to the requirements of Section 15.06 and the
redemption obligations of the Company pursuant to the requirements of
Section 3.05(e);

          (b) subject to Article 4, to convey, transfer, assign, mortgage or
pledge to the Trustee as security for the Notes, any property or assets;

          (c) to evidence the succession of another corporation to the Company,
or successive successions, and the assumption by the successor corporation of
the covenants, agreements and obligations of the Company pursuant to Article 12;

          (d) to add to the covenants of the Company such further covenants,
restrictions or conditions as the Board of Directors and the Trustee shall
consider to be for the benefit of the holders of Notes, and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions or conditions a default or an Event of
Default permitting the enforcement of all or any of the several remedies
provided in this Indenture as herein set forth; PROVIDED that in respect of any
such additional covenant, restriction or condition, such supplemental indenture
may provide for a particular period of grace after default (which period may be
shorter or longer than that allowed in the case of other defaults) or may
provide for an immediate enforcement upon such default or may limit the remedies
available to the Trustee upon such default;

          (e) to provide for the issuance under this Indenture of Notes in
coupon form (including Notes registrable as to principal only) and to provide
for exchangeability of such Notes with the Notes issued hereunder in fully
registered form and to make all appropriate changes for such purpose;

          (f) to cure any ambiguity or to correct or supplement any provision

arising under this Indenture which shall not materially adversely affect the
interests of the holders of the Notes;

          (g) to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Notes; or

          (h) to modify, eliminate or add to the provisions of this Indenture to
such extent as shall be necessary to effect the qualifications of this Indenture
under the Trust Indenture Act, or under any similar federal statute hereafter
enacted.

         Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture, the Trustee
is hereby authorized to join with the Company in the execution of any such
supplemental indenture, to make any further appropriate agreements and
stipulations which may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be
obligated to, but may in its discretion, enter into any supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this
Section 11.01. may be executed by the Company and the Trustee without the
consent of the holders of any of the Notes at the time outstanding,
notwithstanding any of the provisions of Section 11.02.

With the consent (evidenced as provided in Article 9) of the holders of not less
than a majority in aggregate principal amount of the Notes at the time
outstanding, the Company, when authorized by the resolutions of the Board of
Directors, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or any supplemental indenture or of modifying in any manner the
rights of the holders of the Notes; PROVIDED that no such supplemental indenture
shall (i) extend the fixed maturity of any Note, or reduce the rate or extend
the time of payment of interest thereon, or reduce the principal amount thereof
or premium, if any, thereon, or reduce any amount payable on redemption thereof,
or impair the right of any Noteholder to institute suit for the payment thereof,
or make the principal thereof or interest or premium, if any, thereon payable in
any coin or currency other than that provided in the Notes, or modify the
provisions of this Indenture with respect to the subordination of the Notes in a
manner adverse




                                       60

to the Noteholders in any material respect, or change the obligation of the
Company to redeem any Note upon the happening of a Fundamental Change in a
manner adverse to the holder of Notes, or impair the right to convert the
Notes into Common Stock subject to the terms set forth herein, including
Section 15.06, in each case, without the consent of the holder of each Note
so affected, or (ii) reduce the aforesaid percentage of Notes, the holders of
which are required to consent to any such supplemental indenture, without the
consent of the holders of all Notes then outstanding.

         Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and upon
the filing with the Trustee of evidence of the consent of Noteholders as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in is discretion, but shall not be obligated to, enter into
such supplemental indenture.

         It shall not be necessary for the consent of the Noteholders under this
Section 11.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

          SECTION 11.03. EFFECT OF SUPPLEMENTAL INDENTURE. Any supplemental
indenture executed pursuant to the provisions of this Article 11 shall comply
with the Trust Indenture Act, as then in effect; PROVIDED that this Section
11.03 shall not require such supplemental indenture or the Trustee to be
qualified under the Trust Indenture Act prior to the time such qualification
is in fact required under the terms of the Trust Indenture Act or the
Indenture has been qualified under the Trust Indenture Act, nor shall it
constitute any admission or acknowledgment by any party to such supplemental
indenture that any such qualification is required prior to the time such
qualification is in fact required under the terms of the Trust Indenture Act
or the Indenture has been qualified under the Trust Indenture Act. Upon the
execution of any supplemental indenture pursuant to the provisions of this
Article 11, this Indenture shall be and be deemed to be modified and amended
in accordance therewith and the respective rights, limitation of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Notes shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental
indenture shall be and be deemed to be part of the terms and conditions of
this Indenture for any and all purposes.

          SECTION 11.04. NOTATION ON NOTES. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of
this Article 11 may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Notes so modified as to conform, in the opinion
of the Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may, at the Company's expense, be
prepared and executed by the Company, authenticated by the Trustee (or an
authenticating agent duly appointed by the Trustee pursuant to Section 16.11)
and delivered in exchange for the Notes then outstanding, upon surrender of such
Notes then outstanding.

          SECTION 11.05. EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL INDENTURE TO BE
FURNISHED TRUSTEE. Prior to entering into any supplemental indenture, the
Trustee may request an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article 11.



                                   ARTICLE 12
                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

          SECTION 12.01. COMPANY MAY CONSOLIDATE ETC. ON CERTAIN TERMS. Subject
to the provisions of Section 12.02, nothing contained in this Indenture or in
any of the Notes shall prevent any consolidation or merger of the Company with
or into any other corporation or corporations (whether or not affiliated with
the Company), or successive consolidations or mergers in which the Company or
its successor or successors shall be a party or parties, or shall prevent any
sale, conveyance or lease (or successive sales, conveyances or leases) of all or
substantially all of the property of the Company, to any other corporation
(whether or not affiliated with the Company), authorized to acquire and operate
the same and which shall be organized under the laws of the United States of
America, any state thereof or the District of Columbia; PROVIDED that upon any
such consolidation, merger, sale, conveyance or lease, the due and punctual
payment of the principal of and premium, if any, and interest on all of the
Notes, according to their tenor, and the due and punctual performance and
observance of all of the covenants and conditions of this Indenture to be
performed by the Company, shall be expressly assumed, by supplemental indenture
satisfactory in form to the Trustee, executed and delivered to the Trustee by
the corporation (if other than the Company) formed by such consolidation, or
into which the Company shall have been merged, or by the corporation which shall
have


                                       62

<PAGE>



acquired or leased such property, and such supplemental indenture shall provide
for the applicable conversion rights set forth in Section 15.06.

          SECTION 12.02. SUCCESSOR CORPORATION TO BE SUBSTITUTED. In case of any
such consolidation, merger, sale, conveyance or lease and upon the assumption by
the successor corporation, by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the due and punctual
payment of the principal of and premium, if any, and interest on all of the
Notes and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Company, such
successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named herein as the party of the first part.
Such successor corporation thereupon may cause to be signed, and may issue
either in its own name or in the name of the Company any or all of the Notes
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the order of such successor corporation
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver,
or cause to be authenticated and delivered, any Notes which previously shall
have been signed and delivered by the officers of the Company to the Trustee for
authentication, and any Notes which such successor corporation thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All the Notes
so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Notes theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Notes had been issued at the date
of the execution hereof. In the event of any such consolidation, merger, sale,
conveyance or lease, the person named as the "COMPANY" in the first paragraph of
this Indenture or any successor which shall thereafter have become such in the
manner prescribed in this Article 12 may be dissolved, wound up and liquidated
at any time thereafter and such person shall be released from its liabilities as
obligor and maker of the Notes and from its obligations under this Indenture.

         In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form (but not in substance) may be made in the
Notes thereafter to be issued as may be appropriate.

          SECTION 12.03. OPINION OF COUNSEL TO BE GIVEN TRUSTEE. The Trustee
shall receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale, conveyance or lease and any
such assumption complies with the provisions of this Article 12.

                     SATISFACTION AND DISCHARGE OF INDENTURE

          SECTION 13.01. DISCHARGE OF INDENTURE. When (a) the Company shall
deliver to the Trustee for cancellation all Notes theretofore authenticated
(other than any Notes which have been destroyed, lost or stolen and in lieu of
or in substitution for which other Notes shall have been authenticated and
delivered) and not theretofore canceled, or (b) all the Notes not theretofore
canceled or delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall
deposit with the Trustee, in trust, funds sufficient to pay at maturity or upon
redemption of all of the Notes (other than any Notes which shall have been
mutilated, destroyed, lost or stolen and in lieu of or in substitution for which
other Notes shall have been authenticated and delivered) not theretofore
canceled or delivered to the Trustee for cancellation, including principal and
premium, if any, and interest due or to become due to such date of maturity or
redemption date, as the case may be, accompanied by a verification report, as to
the sufficiency of the deposited amount, from an independent certified
accountant or other financial professional satisfactory to the Trustee, and if
the Company shall also pay or cause to be paid all other sums payable hereunder
by the Company, then this Indenture shall cease to be of further effect (except
as to (i) remaining rights of registration of transfer, substitution and
exchange and conversion of Notes, (ii) rights hereunder of Noteholders to
receive payments of principal of and premium, if any, and interest on, the Notes
and the other rights, duties and obligations of Noteholders, as beneficiaries
hereof with respect to the amounts, if any, so deposited with the Trustee and
(iii) the rights, obligations and immunities of the Trustee hereunder), and the
Trustee, on written demand of the Company accompanied by an Officers'
Certificate and an Opinion of Counsel as required by Section 16.05 and at the
cost and expense of the Company, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture; the Company, however, hereby
agreeing to reimburse the Trustee for any costs or expenses thereafter
reasonably and properly incurred by the Trustee and to compensate the Trustee
for any services thereafter reasonably and properly rendered by the Trustee in
connection with this Indenture or the Notes.

          SECTION 13.02. DEPOSITED MONIES TO BE HELD IN TRUST BY TRUSTEE.
Subject to Section 13.04, all monies deposited with the Trustee pursuant to
Section 13.01, provided such deposit was not in violation of Article 4, shall be
held in trust for the sole benefit of the Noteholders and not to be subject to
the subordination provisions of Article 4, and such monies shall be applied by
the

                                       64

<PAGE>



Trustee to the payment, either directly or through any paying agent (including
the Company if acting as its own paying agent), to the holders of the particular
Notes for the payment or redemption of which such monies have been deposited
with the Trustee, of all sums due and to become due thereon for principal and
interest and premium, if any.

          SECTION 13.03. PAYING AGENT TO REPAY MONIES HELD. Upon the
satisfaction and discharge of this Indenture, all monies then held by any paying
agent of the Notes (other than the Trustee) shall, upon written request of the
Company, be repaid to it or paid to the Trustee, and thereupon such paying agent
shall be released from all further liability with respect to such monies.

          SECTION 13.04. RETURN OF UNCLAIMED MONIES. Subject to the requirements
of applicable law, any monies deposited with or paid to the Trustee for payment
of the principal of, premium, if any, or interest on Notes and not applied but
remaining unclaimed by the holders of Notes for two years after the date upon
which the principal of, premium, if any, or interest on such Notes, as the case
may be, shall have become due and payable, shall be repaid to the Company by the
Trustee on demand and all liability of the Trustee shall thereupon cease with
respect to such monies; and the holder of any of the Notes shall thereafter look
only to the Company for any payment which such holder may be entitled to collect
unless an applicable abandoned property law designates another Person.

          SECTION 13.05. REINSTATEMENT. If the Trustee or the paying agent is
unable to apply any money in accordance with Section 13.02 by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 13.01 until such time as the Trustee or the paying
agent is permitted to apply all such money in accordance with Section 13.02;
PROVIDED that if the Company makes any payment of interest or premium on or
principal of any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders of such Notes to
receive such payment from the money held by the Trustee or paying agent.

         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

          SECTION 14.01. INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS. No
recourse for the payment of the principal of or premium, if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any obligation, covenant or agreement of the Company in
this Indenture or in any supplemental indenture or in any Note, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, employee, agent, officer, or director or subsidiary,
past, present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Notes.



                                   ARTICLE 15
                               CONVERSION OF NOTES

          SECTION 15.01. RIGHT TO CONVERT. Subject to and upon compliance
with the provisions of this Indenture, including without limitation Article
4, the holder of any Note shall have the right, at its option, at any time
after original issuance thereof through the close of business on August 1,
2006 (except that, with respect to any Note or portion of a Note which shall
be called for redemption, such right shall terminate, except as provided in
Section 15.02, Section 3.02 or Section 3.04, at the close of business on the
Business Day next preceding the date fixed for redemption of such Note or
portion of a Note unless the Company shall default in payment due upon
redemption thereof) to convert the principal amount of any such Note, or any
portion of such principal amount which is $1,000 or an integral multiple
thereof, into that number of fully paid and non-assessable shares of Common
Stock (as such shares shall then be constituted) obtained by dividing the
principal amount of the Note or portion thereof surrendered for conversion by
the Conversion Price in effect at such time, by surrender of the Note so to
be converted in whole or in part in the manner provided, together with any
required funds, in Section 15.02. A Note in respect of which a holder is
exercising its option to require redemption upon a Fundamental Change
pursuant to Section 3.05 may be converted only if such holder withdraws its
election to exercise in accordance with Section 3.05. A holder of Notes is
not entitled to any rights of a holder of Common Stock until such holder has
converted his Notes to

                                       66

<PAGE>



Common Stock, and only to the extent such Notes are deemed to have been
converted to Common Stock under this Article 15.

          SECTION 15.02. EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON
STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. In order to
exercise the conversion privilege with respect to any Note in definitive form,
the holder of any such Note to be converted in whole or in part shall surrender
such Note, duly endorsed, at an office or agency maintained by the Company
pursuant to Section 5.02, accompanied by the funds, if any, required by this
Section 15.02, and shall give written notice of conversion in the form provided
on the Notes (or such other notice which is acceptable to the Company) to the
office or agency that the holder elects to convert such Note or the portion
thereof specified in said notice. Such notice shall also state the name or names
(with address or addresses) in which the certificate or certificates for shares
of Common Stock which shall be issuable on such conversion shall be issued, and
shall be accompanied by transfer taxes, if required pursuant to Section 15.07.
Each such Note surrendered for conversion shall, unless the shares issuable on
conversion are to be issued in the same name as the registration of such Note,
be duly endorsed by, or be accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or his duly authorized
attorney.

         In order to exercise the conversion privilege with respect to any
interest in a Global Note, the beneficial holder must complete, or cause to be
completed, the appropriate instruction form for conversion pursuant to the
Depository's book-entry conversion program, deliver, or cause to be delivered,
by book-entry delivery an interest in such Global Note, furnish appropriate
endorsements and transfer documents if required by the Company or the Trustee or
conversion agent, and pay the funds, if any, required by this Section 15.02 and
any transfer taxes if required pursuant to Section 15.07.

         As promptly as practicable after satisfaction of the requirements for
conversion set forth above, the Company shall issue and shall deliver to such
holder at the office or agency maintained by the Company for such purpose
pursuant to Section 5.02, a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Note or portion
thereof in accordance with the provisions of this Article and a check or cash in
respect of any fractional interest in respect of a share of Common Stock arising
upon such conversion, as provided in Section 15.03. In case any Note of a
denomination greater than $1,000 shall be surrendered for partial conversion,
and subject to Section 2.03, the Company shall execute and the Trustee shall
authenticate and deliver to the holder of the Note so surrendered, without
charge to him, a new Note or Notes in authorized denominations in an aggregate
principal amount equal to the unconverted portion of the surrendered Note.


                                       67

<PAGE>



         Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 15.02 have been satisfied as to such Note (or portion thereof),
and the Person in whose name any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become on said date the holder of record of the shares represented thereby;
PROVIDED that any such surrender on any date when the stock transfer books of
the Company shall be closed shall constitute the Person in whose name the
certificates are to be issued as the record holder thereof for all purposes on
the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date upon which
such Note shall be surrendered.

         Any Note or portion thereof surrendered for conversion during the
period from the close of business on the record date for any interest payment
date to the close of business on the Business Day next preceding the following
interest payment date that has not been called for redemption during such
period, shall be accompanied by payment, in immediately available funds or other
funds acceptable to the Company, of an amount equal to the interest otherwise
payable on such interest payment date on the principal amount being converted;
PROVIDED that no such payment need be made to the extent any overdue interest
shall exist at the time of conversion with respect to any such Note or portion
thereof. Except as provided above in this Section 15.02, no payment or other
adjustment shall be made for interest accrued on any Note converted or for
dividends on any shares issued upon the conversion of such Note as provided in
this Article.

         Upon the conversion of an interest in a Global Note, the Trustee (or
other conversion agent appointed by the Company), or the Custodian at the
direction of the Trustee (or other conversion agent appointed by the Company),
shall make a notation on such Global Note as to the reduction in the principal
amount represented thereby. The Company shall notify the Trustee in writing of
any conversions of Notes effected through any conversion agent other than the
Trustee.

          SECTION 15.03. CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. No
fractional shares of Common Stock or scrip representing fractional shares shall
be issued upon conversion of Notes. If more than one Note shall be surrendered
for conversion at one time by the same holder, the number of full shares which
shall be issuable upon conversion shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof to the
extent permitted hereby) so surrendered. If any fractional share of stock would
be issuable upon the conversion of any Note or Notes, the Company shall make an
adjustment and payment therefor in cash at the current market price thereof to
the holder of Notes. The current market price of a share of Common Stock shall
be


                                       68

<PAGE>



the Closing Price on the last Trading Day immediately preceding the day on which
the Notes (or specified portions thereof) are deemed to have been converted.

          SECTION 15.04. CONVERSION PRICE. The conversion price shall be as
specified in the form of Note (herein called the "CONVERSION PRICE") attached as
Exhibit A hereto, subject to adjustment as provided in this Article 15.

          SECTION 15.05.  ADJUSTMENT OF CONVERSION PRICE.  The Conversion Price
shall be adjusted from time to time by the Company as follows:

          (a) In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Price in effect at the opening of business on the date
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by multiplying such
Conversion Price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination and the denominator shall be the sum of such number of
shares and the total number of shares constituting such dividend or other
distribution, such reduction to become effective immediately after the opening
of business on the day following the date fixed for such determination. The
Company will not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Company. If any dividend or distribution of
the type described in this Section 15.05(a) is declared but not so paid or made,
the Conversion Price shall not be adjusted pursuant hereto.

          (b) In case the Company shall issue rights or warrants to all holders
of its outstanding shares of Common Stock entitling them (for a period expiring
within forty-five (45) days after the date fixed for determination of
stockholders entitled to receive such rights or warrants) to subscribe for or
purchase shares of Common Stock at a price per share less than the Current
Market Price (as defined below) on the date fixed for determination of
stockholders entitled to receive such rights or warrants, the Conversion Price
shall be reduced so that the Conversion Price shall equal the price determined
by multiplying the Conversion Price in effect immediately prior to the date
fixed for determination of stockholders entitled to receive such rights or
warrants by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for
determination of stockholders entitled to receive such rights and warrants plus
the number of shares which the aggregate offering price of the total number of
shares so offered would purchase at such Current Market Price, and of which the
denominator shall be the number of shares of Common Stock outstanding on the
date fixed for determination of stockholders


                                       69

<PAGE>



entitled to receive such rights and warrants plus the total number of additional
shares of Common Stock offered for subscription or purchase. Such adjustment
shall be successively made whenever any such rights and warrants are issued, and
shall become effective immediately after the opening of business on the day
following the date fixed for determination of stockholders entitled to receive
such rights or warrants. To the extent that shares of Common Stock are not
delivered after the expiration of such rights or warrants, the Conversion Price
shall be readjusted to the Conversion Price which would then be in effect had
the adjustments made upon the issuance of such rights or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually
delivered. If such rights or warrants are not so issued, the Conversion Price
shall not be adjusted pursuant hereto. In determining whether any rights or
warrants entitle the holders to subscribe for or purchase shares of Common Stock
at less than such Current Market Price, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account
any consideration received by the Company for such rights or warrants, the value
of such consideration, if other than cash, to be determined by the Board of
Directors.

          (c) In case outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the Conversion Price in effect
at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately reduced, and conversely,
in case outstanding shares of Common Stock shall be combined into a smaller
number of shares of Common Stock, the Conversion Price in effect at the opening
of business on the day following the day upon which such combination becomes
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

          (d) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock shares of any class of capital stock of the
Company (other than any dividends or distributions to which Section 15.05(a)
applies) or evidences of its indebtedness or assets (including securities, but
excluding any rights or warrants referred to in Section 15.05(b), and excluding
any dividend or distribution (x) paid exclusively in cash or (y) referred to in
Section 15.05(a) (any of the foregoing hereinafter in this Section 15.05(d)
called the "SECURITIES")), then, in each such case (unless the Company elects to
reserve such Securities for distribution to the Noteholders upon the conversion
of the Notes so that any such holder converting Notes will receive upon such
conversion, in addition to the shares of Common Stock to which such holder is
entitled, the amount and kind of such Securities which such holder would have
received if such holder had converted its Notes into Common Stock immediately
prior to the Record Date (as defined in Section 15.05(h) for such distribution
of the Securities)), the


                                       70

<PAGE>



Conversion Price shall be reduced so that the Conversion Price shall be equal to
the price determined by multiplying the Conversion Price in effect on the Record
Date with respect to such distribution by a fraction of which the numerator
shall be the Current Market Price per share of the Common Stock on such Record
Date less the fair market value (as determined by the Board of Directors, whose
determination shall be conclusive, and described in a resolution of the Board if
Directors) on the Record Date of the portion of the Securities so distributed
applicable to one share of Common Stock and the denominator shall be the Current
Market Price per share of the Common Stock on the Record Date, such reduction to
become effective immediately prior to the opening of business on the day
following such Record Date; PROVIDED that if the then fair market value (as so
determined) of the portion of the Securities so distributed applicable to one
share of Common Stock is equal to or greater than the Current Market Price of
the Common Stock on the Record Date, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Noteholder shall have the right to
receive upon conversion the amount of Securities such holder would have received
had such holder converted each Note on the Record Date. If such dividend or
distribution is not so paid or made, the Conversion Price shall again be
adjusted to be the Conversion Price which would then be in effect if such
dividend or distribution had not been declared. If the Board of Directors
determines the fair market value of any distribution for purposes of this
Section 15.05(d) by reference to the actual or when issued trading market for
any securities, it must in doing so consider the prices in such market over the
same period used in computing the Current Market Price of the Common Stock.

         If the Company implements a stockholders' rights plan ("RIGHTS PLAN"),
such Rights Plan must provide that, subject to customary exceptions, upon
conversion of the Notes the holders will receive, in addition to the Common
Stock issuable upon conversion, such rights whether or not such rights have
separated from the Common Stock at the time of such conversion.

         Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("TRIGGER EVENT"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 15.05 (and no adjustment to the Conversion Price under
this Section 15.05 or otherwise will be required or made) until the occurrence
of the earliest Trigger Event, whereupon such rights and warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Price at the time of such Trigger Event shall be
made under this


                                       71

<PAGE>



Section 15.05(d). If any such right or warrant, including any such existing
rights or warrants distributed prior to the date of this Indenture, are subject
to events, upon the occurrence of which such rights or warrants become
exercisable to purchase different securities, evidences of indebtedness or other
assets, then the date of the occurrence of any and each such event shall be
deemed to be the date of distribution and record date with respect to new rights
or warrants with such rights (and a termination or expiration of the existing
rights or warrants without exercise by any of the holders thereof). In addition,
in the event of any distribution (or deemed distribution) of rights or warrants,
or any Trigger Event or other event (of the type described in the preceding
sentence) with respect thereto that was counted for purposes of calculating a
distribution amount for which an adjustment to the Conversion Price under this
Section 15.05 was made, (1) in the case of any such rights or warrants which
shall all have been redeemed or repurchased without exercise by any holders
thereof, the Conversion Price shall be readjusted upon such final redemption or
repurchase to give effect to such distribution or Trigger Event, as the case may
be, as though it were a cash distribution, equal to the per share redemption or
repurchase price received by a holder or holders of Common Stock with respect to
such rights or warrants (assuming such holder had retained such rights or
warrants), made to all holders of Common Stock as of the date of such redemption
or repurchase, and (2) in the case of such rights or warrants which shall have
expired or been terminated without exercise by any holders thereof, the
Conversion Price shall be readjusted as if such rights and warrants had not been
issued.

         For purposes of this Section 15.05(d) and Sections 15.05(a) and (b),
any dividend or distribution to which this Section 15.05(d) is applicable
that also includes shares of Common Stock, or rights or warrants to subscribe
for or purchase shares of Common Stock (or both), shall be deemed instead to
be (1) a dividend or distribution of the evidences of indebtedness, assets or
shares of capital stock other than such shares of Common Stock or rights or
warrants (and any Conversion Price reduction required by this Section
15.05(d) with respect to such dividend or distribution shall then be made)
immediately followed by (2) a dividend or distribution of any such shares of
Common Stock or such rights or warrants (and any further Conversion Price
reduction required by Sections 15.05(a) and (b) with respect to such dividend
or distribution shall then be made), except (A) the Record Date of such
dividend or distribution shall be substituted as "the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution" and "the date fixed for such determination" within the meaning
of Sections 15.05(a) and (b) and (B) any shares of Common Stock included in
such dividend or distribution shall not be deemed "outstanding at the close
of business on the date fixed for such determination" within the meaning of
Section 15.05(a).

                                       72

<PAGE>



          (e) In case the Company shall, by dividend or otherwise, distribute
to all holders of its Common Stock cash (excluding (x) any quarterly cash
dividend on the Common Stock to the extent the aggregate cash dividend per
share of Common Stock in any fiscal quarter does not exceed the greater of
(A) the amount per share of Common Stock of the next preceding quarterly cash
dividend on the Common Stock to the extent that such preceding quarterly
dividend did not require any adjustment of the Conversion Price pursuant to
this Section 15.05(e) (as adjusted to reflect subdivisions or combinations of
the Common Stock), and (B) 3.75% of the arithmetic average of the Closing
Price (determined as set forth in Section 15.05(h)) during the ten Trading
Days (as defined in Section 15.05(h)) immediately prior to the date of
declaration of such dividend, and (y) any dividend or distribution in
connection with the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary), then, in such case, the Conversion Price
shall be reduced so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to the close of
business on the Record Date for such cash distribution by a fraction of which
the numerator shall be the Current Market Price of the Common Stock on the
Record Date less the amount of cash so distributed (and not excluded as
provided above) applicable to one share of Common Stock and the denominator
shall be the Current Market Price of the Common Stock on the Record Date,
such reduction to be effective immediately prior to the opening of business
on the day following the Record Date; PROVIDED that if the portion of the
cash so distributed applicable to one share of Common Stock is equal to or
greater than the Current Market Price of the Common Stock on the Record Date,
in lieu of the foregoing adjustment, adequate provision shall be made so that
each Noteholder shall have the right to receive upon conversion the amount of
cash such holder would have received had such holder converted each Note on
the Record Date. If such dividend or distribution is not so paid or made, the
Conversion Price shall again be adjusted to be the Conversion Price which
would then be in effect if such dividend or distribution had not been
declared. If any adjustment is required to be made as set forth in this
Section 15.05(e) as a result of a distribution that is a quarterly dividend,
such adjustment shall be based upon the amount by which such distribution
exceeds the amount of the quarterly cash dividend permitted to be excluded
pursuant hereto. If an adjustment is required to be made as set forth in this
Section 15.05(e) above as a result of a distribution that is not a quarterly
dividend, such adjustment shall be based upon the full amount of the
distribution.

          (f) In case a tender or exchange offer made by the Company or any
Subsidiary for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to stockholders of consideration per share of Common Stock having a
fair market value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board of Directors)
that as


                                       73

<PAGE>



of the last time (the "EXPIRATION TIME") tenders or exchanges may be made
pursuant to such tender or exchange offer (as it may be amended) exceeds the
Current Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time, the Conversion Price shall be reduced so that the same shall
equal the price determined by multiplying the Conversion Price in effect
immediately prior to the Expiration Time by a fraction of which the numerator
shall be the number of shares of Common Stock outstanding (including any
tendered or exchanged shares) on the Expiration Time multiplied by the Current
Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time and the denominator shall be the sum of (x) the fair market
value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the "PURCHASED SHARES") and (y) the
product of the number of shares of Common Stock outstanding (less any Purchased
Shares) on the Expiration Time and the Current Market Price of the Common Stock
on the Trading Day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time. If the Company is obligated to purchase shares pursuant to any
such tender or exchange offer, but the Company is permanently prevented by
applicable law from effecting any such purchases or all such purchases are
rescinded, the Conversion Price shall again be adjusted to be the Conversion
Price which would then be in effect if such tender or exchange offer had not
been made.

          (g) In case of a tender or exchange offer made by a Person other than
the Company or any Subsidiary for an amount which increases the offeror's
ownership of Common Stock to more than twenty-five percent (25%) of the Common
Stock outstanding and shall involve the payment by such Person of consideration
per share of Common Stock having a fair market value (as determined by the Board
of Directors, whose determination shall be conclusive, and described in a
resolution of the Board of Directors) at the last time (the "OFFER EXPIRATION
TIME") tenders or exchanges may be made pursuant to such tender or exchange
offer (as it shall have been amended) that exceeds the Current Market Price of
the Common Stock on the Trading Day next succeeding the Offer Expiration Time,
and in which, as of the Offer Expiration Time the Board of Directors is not
recommending rejection of the offer, the Conversion Price shall be reduced so
that the same shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to the Offer Expiration Time by a fraction of
which the numerator shall be the number of shares of Common Stock outstanding
(including any tendered or exchanged shares) on the Offer Expiration Time
multiplied by the Current Market Price of the Common Stock on the Trading Day
next succeeding the Offer Expiration Time and the denominator




                                       74

<PAGE>



shall be the sum of (x) the fair market value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to
any maximum specified in the terms of the tender or exchange offer) of all
shares validly tendered or exchanged and not withdrawn as of the Offer
Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "ACCEPTED PURCHASED SHARES") and (y) the product of the
number of shares of Common Stock outstanding (less any Accepted Purchased
Shares) on the Offer Expiration Time and the Current Market Price of the Common
Stock on the Trading Day next succeeding the Offer Expiration Time, such
reduction to become effective immediately prior to the opening of business on
the day following the Offer Expiration Time. If such Person is obligated to
purchase shares pursuant to any such tender or exchange offer, but such Person
is prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such tender or exchange offer
had not been made. Notwithstanding the foregoing, the adjustment described in
this Section 15.05(g) shall not be made if, as of the Offer Expiration Time, the
offering documents with respect to such offer disclose a plan or intention to
cause the Company to engage in or otherwise involve the Company engaging in any
transaction described in Article 12.

          (h) For purposes of this Section 15.05, the following terms shall have
the meaning indicated:

               (i) "CLOSING PRICE" with respect to any securities on any day
          means the closing sale price regular way on such day or, in case no
          such sale takes place on such day, the average of the reported closing
          bid and asked prices, regular way, in each case on the New York Stock
          Exchange, or, if such security is not listed or admitted to trading on
          such Exchange, on the principal national security exchange or
          quotation system on which such security is quoted or listed or
          admitted to trading, or, if not quoted or listed or admitted to
          trading on any national securities exchange or quotation system, the
          average of the closing bid and asked prices of such security on the
          over-the-counter market on the day in question as reported by the
          National Quotation Bureau Incorporated, or a similar generally
          accepted reporting service, or if not so available, in such manner as
          furnished by any New York Stock Exchange member firm selected from
          time to time by the Board of Directors for that purpose, or a price
          determined in good faith by the Board of Directors or, to the extent
          permitted by applicable law, a duly authorized committee thereof,
          whose determination shall be conclusive.





                                       75

<PAGE>



               (ii) For purposes of any computation under Section 15.05(b), (d)
          or (e), "CURRENT MARKET PRICE" means the average of the daily Closing
          Prices per share of Common Stock for the ten consecutive Trading Days
          immediately prior to the date in question; PROVIDED that (1) if the
          "ex" date (as hereinafter defined) for any event (other than the
          issuance or distribution requiring such computation) that requires an
          adjustment to the Conversion Price pursuant to Section 15.05(a), (b),
          (c), (d), (e), (f) or (g) occurs during such ten consecutive Trading
          Days, the Closing Price for each Trading Day prior to the "ex" date
          for such other event shall be adjusted by multiplying such Closing
          Price by the same fraction by which the Conversion Price is so
          required to be adjusted as a result of such other event, (2) if the
          "ex" date for any event (other than the issuance or distribution
          requiring such computation) that requires an adjustment to the
          Conversion Price pursuant to Section 15.05(a), (b), (c), (d), (e), (f)
          or (g) occurs on or after the "ex" date for the issuance or
          distribution requiring such computation and prior to the date in
          question, the Closing Price for each Trading Day on and after the "ex"
          date for such other event shall be adjusted by multiplying such
          Closing Price by the reciprocal of the fraction by which the
          Conversion Price is so required to be adjusted as a result of such
          other event, and (3) if the "ex" date for the issuance or distribution
          requiring such computation is prior to the date in question, after
          taking into account any adjustment required pursuant to clause (1) or
          (2) of this proviso, the Closing Price for each Trading Day on or
          after such "ex" date shall be adjusted by adding thereto the amount of
          any cash and the fair market value (as determined by the Board of
          Directors or, to the extent permitted by applicable law, a duly
          authorized committee thereof in a manner consistent with any
          determination of such value for purposes of Section 15.05(d), (f) or
          (g), whose determination shall be conclusive and described in a
          resolution of the Board of Directors or such duly authorized committee
          thereof, as the case may be) of the evidences of indebtedness, shares
          of capital stock or assets being distributed applicable to one share
          of Common Stock as of the close of business on the day before such
          "ex" date.

                    For purposes of any computation under Section 15.05(f) or
         (g), the CURRENT MARKET PRICE of the Common Stock on any date shall be
         deemed to be the average of the daily Closing Prices per share of
         Common Stock for such day and the next two succeeding Trading Days;
         PROVIDED that if the "ex" date for any event (other than the tender or
         exchange offer requiring such computation) that requires an adjustment
         to the Conversion Price pursuant to Section 15.05(a), (b), (c), (d),
         (e), (f) or (g) occurs on or after the Expiration Time or Offer
         Expiration Time, as the case may be, for the tender or exchange offer
         requiring such computation and before the



                                       76

<PAGE>



         end of the averaging period used to calculate the Current Market Price,
         the Closing Price for each Trading Day on and after the "ex" date for
         such other event shall be adjusted by multiplying such Closing Price by
         the reciprocal of the fraction by which the Conversion Price is so
         required to be adjusted as a result of such other event.

                  For purposes of the definition of Current Market Price, the
         term "EX" date, (1) when used with respect to any issuance or
         distribution, means the first date on which the Common Stock trades
         regular way on the relevant exchange or in the relevant market from
         which the Closing Price was obtained without the right to receive such
         issuance or distribution, (2) when used with respect to any subdivision
         or combination of shares of Common Stock, means the first date on which
         the Common Stock trades regular way on such exchange or in such market
         after the time at which such subdivision or combination becomes
         effective, and (3) when used with respect to any tender or exchange
         offer means the first date on which the Common Stock trades regular way
         on such exchange or in such market after the last time tenders or
         exchanges may be made pursuant to such tender or exchange offer.

               (iii) "FAIR MARKET VALUE" means the amount which a willing buyer
          would pay a willing seller in an arm's length transaction.

               (iv) "RECORD DATE" means, with respect to any dividend,
          distribution or other transaction or event in which the holders of
          Common Stock have the right to receive any cash, securities or other
          property or in which the Common Stock (or other applicable security)
          is exchanged for or converted into any combination of cash,
          securities or other property, the date fixed for determination of
          stockholders entitled to receive such cash, securities or other
          property (whether such date is fixed by the Board of Directors
          or by statute, contract or otherwise).

               (v) "TRADING DAY" means (x) if the applicable security is listed
          or admitted for trading on the New York Stock Exchange or another
          national security exchange, a day on which the New York Stock
          Exchange or such other national security exchange is open for
          business or (y) if the applicable security is quoted on the Nasdaq
          National Market, a day on which trades may be made thereon or (z) if
          the applicable security is not so listed, admitted for trading or
          quoted, any day other than a Saturday or Sunday or a day on which
          banking institutions in the State of New York are authorized or
          obligated by law or executive order to close.




                                       77

          (i) The Company may make such reductions in the Conversion Price, in
addition to those required by Sections 15.05(a), (b), (c), (d), (e), (f) or (g)
as the Board of Directors considers to be advisable to avoid or diminish any
income tax to holders of Common Stock or rights to purchase Common Stock
resulting from any subdivision of stock, dividend or distribution of stock or
securities convertible into or exchangeable for stock, (or rights to acquire
stock) or from any event treated as such for income tax purposes.

         To the extent permitted by applicable law, the Company from time to
time may reduce the Conversion Price by any amount for any period of time if the
period is at least twenty (20) days, the reduction is irrevocable during the
period and the Board of Directors shall have made a determination that such
reduction would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Price is reduced pursuant to the
preceding sentence, the Company shall mail to holders of record of the Notes a
notice of the reduction at least fifteen (15) days prior to the date the reduced
Conversion Price takes effect, and such notice shall state the reduced
Conversion Price and the period during which it will be in effect.

          (j) No adjustment in the Conversion Price under any provision of this
Section 15.05 shall be required unless such adjustment would require an increase
or decrease of at least one percent (1%) in such price; PROVIDED that any
adjustments which by reason of this Section 15.05(j) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Article 15 shall be made by the Company and shall be
made to the nearest cent or to the nearest one-hundredth (1/100) of a share, as
the case may be. Notwithstanding the other premises of this Section 15.05, no
adjustment need be made for rights to purchase Common Stock pursuant to a
Company plan for reinvestment of dividends or other distributions or interest.
To the extent the Notes become convertible into cash, assets, property or
securities (other than capital stock of the Company), no adjustment need be made
thereafter as to the cash, assets, property or such securities. Interest will
not accrue on the cash.

          (k) Whenever the Conversion Price is adjusted as herein provided, the
Company shall promptly file with the Trustee and any conversion agent other than
the Trustee an Officers' Certificate setting forth the Conversion Price after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Price setting forth the
adjusted Conversion Price and the date on which each adjustment becomes
effective and shall mail such notice to the holder of each Note at his last
address appearing on the Note register provided for in Section 2.05 of this
Indenture,



                                       78

<PAGE>



within twenty (20) days after execution thereof. Failure to deliver such notice
shall not affect the legality or validity of any such adjustment.

          (l) In any case in which this Section 15.05 provides that an
adjustment shall become effective immediately after a record date for an event,
the Company may defer until the occurrence of such event (i) issuing to the
holder of any Note converted after such record date and before the occurrence of
such event the additional shares of Common Stock issuable upon such conversion
by reason of the adjustment required by such event over and above the Common
Stock issuable upon such conversion before giving effect to such adjustment and
(ii) paying to such holder any amount in cash in lieu of any fraction pursuant
to Section 15.03. If the event does not in fact occur, no additional
distribution shall be required, as contemplated by this Section 15.05.

          (m) For purposes of this Section 15.05, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company will not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

          SECTION 15.06. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR
SALE. If any of the following events occur, namely (i) any reclassification or
change of the outstanding shares of Common Stock (other than a subdivision or
combination to which Section 15.05(c) applies), (ii) any consolidation, merger
or combination of the Company with another corporation as a result of which
holders of Common Stock shall be entitled to receive stock, securities or other
property or assets (including cash) with respect to or in exchange for such
Common Stock, or (iii) any sale or conveyance of the properties and assets of
the Company as, or substantially as, an entirety to any other corporation as a
result of which holders of Common Stock shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock, then the Company or the successor or purchasing
corporation, as the case may be, shall execute with the Trustee a supplemental
indenture (which shall comply with the Trust Indenture Act as in force at the
date of execution of such supplemental indenture) providing that such Note shall
be convertible into the kind and amount of shares of stock and other securities
or property or assets (including cash) receivable upon such reclassification,
change, consolidation, merger, combination, sale or conveyance by a holder of a
number of shares of Common Stock issuable upon conversion of such Notes
(assuming, for such purposes, a sufficient number of authorized shares of Common
Stock available to convert all such Notes) immediately prior to such
reclassification, change, consolidation, merger, combination, sale or conveyance
assuming such holder of Common Stock did not



                                       79

<PAGE>



exercise his rights of election, if any, as to the kind or amount of securities,
cash or other property receivable upon such consolidation, merger, statutory
exchange, sale or conveyance (PROVIDED that, if the kind or amount of
securities, cash or other property receivable upon such consolidation, merger,
statutory exchange, sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election shall not have been exercised
("NON-ELECTING SHARE"), then for the purposes of this Section 15.06 the kind and
amount of securities, cash or other property receivable upon such consolidation,
merger, statutory exchange, sale or conveyance for each non-electing share shall
be deemed to be the kind and amount so receivable per share by a plurality of
the non-electing shares). Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article.

         The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at its address appearing on the
Note register provided for in Section 2.05 of this Indenture, within twenty (20)
days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

         The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

         Notwithstanding the premises of Section 15.05, if this Section 15.06
applies to any event or occurrence, Section 15.05 shall not apply.

          SECTION 15.07. TAXES ON SHARES ISSUED. The issue of stock certificates
on conversions of Notes shall be made without charge to the converting
Noteholder for any tax in respect of the issue thereof. The Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of stock in any name other than that
of the holder of any Note converted, and the Company shall not be required to
issue or deliver any such stock certificate unless and until the Person or
Persons requesting the issue thereof shall have paid to the Company the amount
of such tax or shall have established to the satisfaction of the Company that
such tax has been paid.

          SECTION 15.08. RESERVATION OF SHARES; SHARES TO BE FULLY PAID;
COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS; LISTING OF COMMON STOCK. The Company
shall provide, free from preemptive rights, out of its authorized but unissued
shares or shares held in treasury, sufficient shares of Common Stock to provide
for the conversion of the Notes from time to time as such Notes are presented
for conversion.




                                       80

         Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company will take all corporate
action which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Price.

         The Company covenants that all shares of Common Stock which may be
issued upon conversion of Notes will upon issue be fully paid and non-assessable
by the Company and free from all unpaid taxes, liens and charges with respect to
the issue thereof.

         The Company covenants that if any shares of Common Stock to be provided
for the purpose of conversion of Notes hereunder require registration with or
approval of any governmental authority under any federal or state law before
such shares may be validly issued upon conversion, the Company will in good
faith and as expeditiously as possible endeavor to secure such registration or
approval, as the case may be.

         The Company further covenants that if at any time the Common Stock
shall be listed on the Nasdaq National Market or any other national securities
exchange or automated quotation system the Company will, if permitted by the
rules of such exchange or automated quotation system, list and keep listed, so
long as the Common Stock shall be so listed on such exchange or automated
quotation system, all Common Stock issuable upon conversion of the Notes;
PROVIDED that if rules of such exchange or automated quotation system permit the
Company to defer the listing of such Common Stock until the first conversion of
the Notes into Common Stock in accordance with the provisions of this Indenture,
the Company covenants to list such Common Stock issuable upon conversion of the
Notes in accordance with the requirements of such exchange or automated
quotation system at such time.

          SECTION 15.09. RESPONSIBILITY OF TRUSTEE. The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine the Conversion Price or whether any facts exist
which may require any adjustment of the Conversion Price, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. The Trustee and any other
conversion agent shall not be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities or
property, which may at any time be issued or delivered upon the conversion of
any Note; and the Trustee and any other conversion agent make no representations
with respect


                                       81

thereto. Neither the Trustee nor any conversion agent shall be responsible for
any failure of the Company to issue, transfer or deliver any shares of Common
Stock or stock certificates or other securities or property or cash upon the
surrender of any Note for the purpose of conversion or to comply with any of the
duties, responsibilities or covenants of the Company contained in this Article.
Without limiting the generality of the foregoing, neither the Trustee nor any
conversion agent shall be under any responsibility to determine the correctness
of any provisions contained in any supplemental indenture entered into pursuant
to Section 15.06 relating either to the kind or amount of shares of stock or
securities or property (including cash) receivable by Noteholders upon the
conversion of their Notes after any event referred to in such Section 15.06 or
to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 8.01, may accept as conclusive evidence of the correctness
of any such provisions, and shall be protected in relying upon, the Officers'
Certificate (which the Company shall be obligated to file with the Trustee prior
to the execution of any such supplemental indenture) with respect thereto.

          SECTION 15.10.  NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.  In case:

          (a) the Company shall declare a dividend (or any other distribution)
on its Common Stock that would require an adjustment in the Conversion Price
pursuant to Section 15.05; or

          (b) the Company shall authorize the granting to the holders of all or
substantially all of its Common Stock of rights or warrants to subscribe for or
purchase any share of any class or any other rights or warrants; or

          (c) of any reclassification or reorganization of the Common Stock of
the Company (other than a subdivision or combination of its outstanding Common
Stock, or a change in par value, or from par value to no par value, or from no
par value to par value), or of any consolidation or merger to which the Company
is a party and for which approval of any stockholders of the Company is
required, or of the sale or transfer of all or substantially all of the assets
of the Company or any Significant Subsidiary; or

          (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company or any Significant Subsidiary;

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at its address appearing on the Note register provided for in
Section 2.05 of this Indenture, as promptly as possible but in any event at
least fifteen (15) days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend,



                                       82

<PAGE>



distribution or rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distribution or rights are to be determined, or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective or occur, and the date
as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up. Failure to give such notice, or any
defect therein, shall not affect the legality or validity of such dividend,
distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

                                       85

<PAGE>



including under Sections 2.04, 2.05, 2.06, 2.07, 3.03 and 3.05, as fully to all
intents and purposes as though the authenticating agent had been expressly
authorized by this Indenture and those Sections to authenticate and deliver
Notes. For all purposes of this Indenture, the authentication and delivery of
Notes by the authenticating agent shall be deemed to be authentication and
delivery of such Notes "by the Trustee" and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to
satisfy any requirement hereunder or in the Notes for the Trustee's certificate
of authentication. Such authenticating agent shall at all times be a Person
eligible to serve as trustee hereunder pursuant to Section 8.09.

         Any corporation into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any authenticating agent
shall be a party, or any corporation succeeding to the corporate trust business
of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this
Section 16.11, without the execution or filing of any paper or any further act
on the part of the parties hereto or the authenticating agent or such successor
corporation.

         Any authenticating agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time terminate the agency of any authenticating agent by giving written notice
of termination to such authenticating agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any authenticating agent shall cease to be eligible under this Section, the
Trustee shall either promptly appoint a successor authenticating agent or itself
assume the duties and obligations of the former authenticating agent under this
Indenture, and upon such appointment of a successor authenticating agent, if
made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of
a successor authenticating agent to all holders of Notes as the names and
addresses of such holders appear on the Note register.

         The Trustee agrees to pay to the authenticating agent from time to
time reasonable compensation for its services (to the extent pre-approved by
the Company in writing), and the Trustee shall be entitled to be reimbursed
for such pre-approved payments, subject to Section 8.06.

         The provisions of Sections 8.02, 8.03, 8.04, 9.03 and this
Section 16.11 shall be applicable to any authenticating agent.

declaration accelerating the maturity of the Notes, the holders of a majority in
aggregate principal amount of the Notes at the time outstanding may on behalf of
the holders of all of the Notes waive any past default or Event of Default under
the Indenture and its consequences except a default in the payment of interest
or any premium on or the principal of any of the Notes, a default in the payment
of redemption price pursuant to Article 3 of the Indenture or a failure by the
Company to convert any Notes into Common Stock. Any such consent or waiver by
the holder of this Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners
of this Note and any Notes which may be issued in exchange or substitution
hereof, irrespective of whether or not any notation thereof is made upon this
Note or such other Notes.

         The indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, expressly subordinate, junior and subject in
right of payment to the prior payment in full of all Senior Indebtedness of the
Company, as defined in the Indenture, whether outstanding at the date of the
Indenture or thereafter incurred, and this Note is issued subject to the
provisions of the Indenture with respect to such subordination. Each holder of
this Note, by accepting the same, agrees to and shall be bound by such
provisions and authorizes the Trustee on its behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee his attorney-in-fact for such purpose.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective times, at the rate and in the coin
or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day year
of twelve 30-day months.

         The Notes are issuable in registered form without coupons in
denominations of $1,000 and any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof, and in the manner and
subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in connection with any
registration or exchange of Notes, Notes may be exchanged for a like aggregate
principal amount of Notes of other authorized denominations.

and 100% at August 1, 2006; PROVIDED that if the date fixed for redemption is on
February 1 or August 1, then the interest payable on such date shall be paid to
the holder of record on the next preceding January 15 or July 15, respectively.

         The Notes are not subject to redemption through the operation of any
sinking fund.

         If a Fundamental Change (as defined in the Indenture) occurs at any
time prior to August 1, 2006, the Notes will be redeemable on the 30th day
after notice thereof at the option of the holder. Such repayment shall be
made at a price equal to 100% of the principal amount to be redeemed. The
Company shall also pay accrued interest, if any, on such Notes to, but
excluding, the Repurchase Date; PROVIDED that if such Repurchase Date is
February 1 or August 1, then the interest payable on such date shall be paid
to the holder of record of the Note on the next preceding January 15 or July
15. The Company shall mail to all holders of record of the Notes a notice of
the occurrence of a Fundamental Change and of the redemption right arising as
a result thereof on or before the 10th day after the occurrence of such
Fundamental Change. For a Note to be so redeemed at the option of the holder,
the Company must receive at the office or agency of the Company maintained
for that purpose in accordance with the terms of the Indenture, such Note
with the form entitled "Option to Elect Repayment Upon a Fundamental Change"
on the reverse thereof duly completed, together with such Notes duly endorsed
for transfer, on or before the close of business on the 30th

                                       A-7

day after the date of such notice (or if such 30th day is not a Business Day,
the immediately preceding Business Day).

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after the date of original issuance hereof
through the close of business on August 1, 2006, or, as to all or any portion
hereof called for redemption, prior to the close of business on the Business Day
immediately preceding the date fixed for redemption (unless the Company shall
default in payment due upon redemption thereof), to convert the principal hereof
or any portion of such principal which is $1,000 or an integral multiple thereof
into that number of shares of the Company's Common Stock, as said shares shall
be constituted at the date of conversion, obtained by dividing the principal
amount of this Note or portion thereof to be converted by the Conversion Price
of $_____ or such Conversion Price as adjusted from time to time as provided in
the Indenture, upon surrender of this Note, together with a conversion notice as
provided in the Indenture, to the Company at the office or agency of the Company
maintained for that purpose in accordance with the terms of the Indenture, and,
unless the shares issuable on conversion are to be issued in the same name as
this Note, duly endorsed by, or accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or by his duly
authorized attorney.

         No adjustment in respect of interest on any Note converted or dividends
on any shares issued upon conversion of such Note will be made upon any
conversion; PROVIDED that if this Note shall be surrendered for conversion
during the period from the close of business on any record date for the payment
of interest to the close of business on the Business Day preceding the interest
payment date and has not been called for redemption during this period, this
Note must be accompanied by payment, in immediately available funds or other
funds acceptable to the Company, of an amount equal to the interest otherwise
payable on such interest payment date on the principal amount being converted;
PROVIDED that no such payment need be made to the extent any overdue interest
shall exist at the time of conversion with respect to such Note.

         No fractional shares will be issued upon any conversion, but an
adjustment and payment in cash will be made, as provided in the Indenture, in
respect of any fraction of a share which would otherwise be issuable upon the
surrender of any Note or Notes for conversion.

         A Note in respect of which a holder is exercising its right to require
redemption upon a Fundamental Change may be converted only if such holder
withdraws its election to exercise such right in accordance with the terms of
the Indenture.

         Any Notes called for redemption, unless surrendered for conversion on
or before the close of business on the Business Day preceding the date fixed for
redemption, may be deemed to be redeemed from the holders of such Notes for an
amount equal to the applicable redemption price, together with accrued but
unpaid interest to (but excluding) the date fixed for redemption, by one or more
investment bankers or other purchasers who may agree with the Company to
purchase such Notes from the holders thereof and convert them into Common Stock
and to make payment for such Notes as aforesaid to the Trustee in trust for such
holders.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, a new Note or Notes of authorized denominations for
an equal aggregate principal amount will be issued to the transferee in exchange
thereof, subject to the limitations provided in the Indenture, without charge
except for any tax, assessment or other governmental charge imposed in
connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Note (whether or not this Note shall
be overdue and notwithstanding any notation of ownership or other writing hereon
made by anyone other than the Company or any Note registrar), for the purpose of
receiving payment hereof, or on account hereof, for the conversion hereof and
for all other purposes, and neither the Company nor the Trustee nor any other
authenticating agent nor any paying agent nor any other conversion agent nor any
Note registrar shall be affected by any notice to the contrary. All payments
made to or upon the order of such registered holder shall, to the extent of the
sum or sums paid, satisfy and discharge liability for monies payable on this
Note.

         No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof; and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any supplemental indenture thereto or in any
Note, or because of the creation of any indebtedness represented thereby, or
otherwise shall be had against any incorporator, stockholder, employee, agent,
officer or director or subsidiary, as such, past, present or future, of the
Company or of any successor corporation, either directly or through the Company
or any successor corporation, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise, all
such liability being, by the acceptance hereof and as part of the consideration
for the issue hereof, expressly waived and released.

                                    REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

                  We have acted as special counsel to priceline.com
Incorporated, a Delaware corporation (the "Company"), in connection with the
public offering by the Company and certain selling stockholders of the
Company (the "Selling Stockholders") of up to 6,325,000 shares (the "Shares")

requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of
1933, as amended (the "Act").

                  In connection with this opinion, we have exam ined
originals or copies, certified or otherwise identified to our satisfaction,

to the Shares, the Notes and the Conversion Shares as filed with the Securities

Agreement (the "Stock Underwriting Agreement") proposed to be entered into by
and among the Company, the Selling Stockholders and Morgan Stanley & Co.
Incorporated, Goldman, Sachs & Co., Allen & Company Incorporated,

together with the U.S. Stock Underwriters, the "Stock Underwriters"),

form of global certificate representing the Notes; (vii) a specimen

                                       2

certificate representing Common Stock; (viii) the form of the Indenture for
the Notes (the "Indenture") to be entered into by and between the Company and
Wilmington Trust Company as trustee for the holders of the Notes (the
"Trustee"); (ix) the Form T-1 of the Trustee filed as an exhibit to the
Registration Statement; (x) the Certificate of Incorporation of the Company,
as currently in effect; (xi) the By-Laws of the Company, as currently in
effect; and (xii) certain resolutions of the Board of Directors of the
Company, dated July 29, 1999, and drafts of certain resolutions (the "Draft
Resolutions") of the Pricing Committee of the Board of Directors of the
Company (the "Pricing Committee"), relating to the issuance of the Primary
Shares, the Notes and the Conversion Shares and the sale of the Secondary
Shares and related matters. We also have examined originals or copies,
certified or otherwise identified to our satisfaction, of such records of the
Company and such agreements, certificates of public officials, certificates
of officers or other representatives of the Company and others, and such
other documents, certificates and records as we have deemed necessary or
appropriate as a basis for the opinions set forth herein.

                  In our examination, we have assumed the legal capacity of
all natural persons, the genuineness of all signatures, the authenticity of
all documents submitted to us as originals, the conformity to original
documents of all documents submitted to us as certified, conformed or
photostatic copies and the authenticity of the originals of such latter
documents. In making our examination of documents executed or to be executed,
we have assumed that the parties thereto, other than the Company, had or will
have the power, corporate or other, to enter into and perform all obligations
thereunder and have also assumed the due authorization by all requisite
action, corporate or other, and execution and delivery by such parties of
such documents and the validity and binding effect thereof on such parties.
As to any facts material to the opinions expressed herein which we have not
independently established or verified, we have relied upon statements and
representations of officers and other representatives of the Company and
others.

                  In rendering the opinions set forth in paragraphs 1 and 3
below, we have assumed that the certificates representing the Primary Shares
and the Conversion Shares will be manually signed by one of the authorized
officers of the Transfer Agent and Registrar for the Common Stock and
registered by such Transfer Agent and Registrar and will conform

                                       3
<PAGE>

to the specimen certificate representing Common Stock examined by us.

                  Our opinions set forth herein are limited to Delaware
corporate law and the laws of the State of New York which are normally
applicable to transactions of the type contemplated by the Indenture and the
Notes and, to the extent that judicial or regulatory orders or decrees or con
sents, approvals, licenses, authorizations, validations, filings, recordings
or registrations with governmental authorities are relevant, to those
required under such laws (all of the foregoing being referred to as "Opined
on Law"). We do not express any opinion with respect to the law of any
jurisdiction other than Opined on Law or as to the effect of any non-Opined
on Law on the opinions herein stated.

                  Based upon and subject to the foregoing, we are of the opinion
that when (i) the Registration Statement becomes effective under the Act and the
Indenture has been qualified under the Trust Indenture Act of 1939, as amended;
(ii) the price at which the Shares are to be sold to the Stock Underwriters
pursuant to the Stock Underwriting Agreement and other matters relating to the
issuance and sale of the Primary Shares have been approved by the Pricing
Committee in accordance with the Draft Resolutions; (iii) the Stock Underwriting
Agreement has been duly executed and delivered; (iv) the Primary Shares have
been delivered to and paid for by the Stock Underwriters at a price per share
not less than the per share par value of the Common Stock as contemplated by the
Stock Underwriting Agreement; (v) the interest rate, maturity, redemption,
conversion and other terms of the Notes, as well as the price at which the Notes
are to be sold to the Note Underwriters pursuant to the Note Underwriting
Agreement and other matters relating to the issuance and sale of the Notes, have
been approved by the Pricing Committee in accordance with the Draft Resolu
tions; (vi) the Notes Underwriting Agreement has been duly executed and
delivered; (vii) the Indenture has been duly executed and delivered; and (viii)
the Notes have been duly executed and authenticated in accordance with the terms
of the Indenture and delivered to and paid for by the Notes Underwriters as
contemplated by the Notes Under writing Agreement:

         (1) The Primary Shares will be validly issued, fully
paid and nonassessable.


                                       4
<PAGE>

         (2) The Notes will constitute valid and binding obligations of the
Company, entitled to the benefits of the Indenture and enforceable against
the Company in accordance with their terms, except to the extent that
enforcement thereof may be limited by (a) bankruptcy, insolvency (including,
without limitation, all laws relating to fraudulent transfers), reorganiza
tion, moratorium or other similar laws now or hereafter in effect relating to
creditors' rights generally and (b) general principles of equity (regardless
of whether enforcement is considered in a proceeding in equity or at law)
and, except that the waiver contained in Section 5.08 of the Indenture may be
unenforceable;

         (3) The shares of Common Stock initially issuable upon conversion of
the Notes, if and when the Notes are converted into shares of Common Stock in
accordance with their terms and the terms of the Indenture, will be validly
issued, fully paid and nonassessable.

                  In rendering the opinions set forth above, we have assumed
that the execution and delivery by the Company of the Notes and the Indenture
and the performance by the Company of its obligations thereunder do not and
will not violate, conflict with or constitute a default under any agreement or
instrument to which the Company or its properties is subject, except for those
agreements and instruments which were identified to us by the Company as being
material to it and which are included as exhibits to the Registration
Statement.

                  We hereby consent to the filing of this opinion with the
Commission as Exhibit 5.1 to the Registration Statement. We also consent to the
reference to us under the caption "Legal Matters" in the Registration State
ment. In giving this consent, we do not thereby admit that we are included in
the category of persons whose consent is required under Section 7 of the Act or
the rules and regulations of the Commission.


                                                 Very truly yours,

                                    REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

                  I am Senior Vice President, General Counsel and Secretary of
priceline.com Incorporated, a Delaware corporation (the "Company"), and have
acted as general counsel to the Company in relation to the public offering by
the Company and certain selling stockholders of the Company (the "Selling
Stockholders") of up to 6,325,000 shares (the "Shares") of the Company's common
stock, par value $0.008 per share (the "Common Stock"). Of the Shares, 2,000,000
shares of Common Stock (the "Primary Shares") are being sold by the Company and
up to 4,325,000 shares of Common Stock (the "Secondary Shares") are being sold
by the Selling Stockholders, including 825,000 shares of Common Stock to be sold
by the Selling Stockholders if the underwriters (the "Underwriters") exercise
their over-allotment option.

                  This opinion is being furnished in accordance with the
requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of
1933, as amended (the "Act").

                  In connection with this opinion, I have examined originals or
copies, certified or otherwise identified to my satisfaction, of (i) the
Registration Statement on Form S-1 (File No. 333-83513) as filed with the
Securities and Exchange Commission (the "Commission") on July 23, 1999 under the
Act; (ii) Amendment No. 1 to the Registration Statement as filed with the
Commission on August 2, 1999 under the Act; (iii) Amendment No. 2 to the
Registration Statement as filed with the Commission on August 10, 1999 under the
Act (such Registration Statement, as so
<PAGE>

amended, being hereinafter referred to as the "Registration Statement"); (iv) a
specimen certificate representing Common Stock; (v) the Certificate of
Incorporation of the Company, as currently in effect and as in effect at the
time of original issuance and sale of the Secondary Shares; (vi) the By-Laws of
the Company, as currently in effect and as in effect at the time of original
issuance and sale of the Secondary Shares; (vii) certain resolutions of the
Board of Directors of the Company, relating to the original issuance and sale of
the Secondary Shares and related matters; (viii) the Participation Warrant
Agreement, dated August 31, 1998, between the Company and Delta Air Lines, Inc.
("Delta"), as amended on December 31, 1998 (the "Delta Warrant"); and (ix) cross
receipts, acknowledgments and other documents evidencing receipt by the Company
of the original issue price for the Secondary Shares, but excluding the
Secondary Shares (the "Delta Secondary Shares") to be issued on exercise by
Delta of warrants pursuant to the Delta Warrant immediately prior to sale of the
Secondary Shares to the Underwriters. I also have examined originals or copies,
certified or otherwise identified to my satisfaction, of such records of the
Company and such agreements, certificates of public officials, certificates of
officers or other representatives of the Company and others, and such other
documents, certificates and records as I have deemed necessary or appropriate as
a basis for the opinions set forth herein.

                  In my examination, I have assumed the legal capacity of all
natural persons, the genuineness of all signatures, the authenticity of all
documents submitted to me as originals, the conformity to original documents of
all documents submitted to me as certified, conformed or photostatic copies and
the authenticity of the originals of such latter documents. In making my
examination of executed documents, I have assumed that the parties thereto,
other than the Company, had the power, corporate or other, to enter into and
perform all obligations thereunder and have also assumed the due authorization
by all requisite action, corporate or other, and execution and delivery by such
parties of such documents and the validity and binding effect thereof on such
parties. As to any facts material to the opinions expressed herein which I have
not independently established or verified, I have relied upon statements and
representations of officers and other representatives of the Company and others.

                  In rendering the opinion set forth in paragraph 2 below, I
have also assumed, with your consent, that the certificates representing the
Delta Secondary
<PAGE>

Shares will be manually signed by one of the authorized officers of the Transfer
Agent and Registrar for the Common Stock and registered by such Transfer Agent
and Registrar and will conform to the specimen thereof examined by me.

                  I am the Senior Vice President, General Counsel and Secretary
of the Company, and have held such position since September 1998. I am admitted
to the bar in the State of Connecticut and I do not express any opinion as to
the laws of any other jurisdiction other than the General Corporation Law of the
State of Delaware.

                  Based upon and subject to the foregoing, I am of the opinion
that

                  1. The original issuance and sale of the Secondary Shares
(other than the Delta Secondary Shares) has been duly authorized by the Company,
and such Secondary Shares are validly issued, fully paid and nonassessable
shares of Common Stock.

                  2. The issuance and sale of the Delta Secondary Shares has
been duly authorized by the Company and when Delta has duly exercised its
warrants for the issuance of the Delta Secondary Shares and paid the exercise
price for such warrants to the Company and the Company has issued and delivered
Common Stock comprising the Delta Secondary Shares to Delta, in each case in
accordance with the Delta Warrant, the Delta Secondary Shares will have been
validly issued, fully paid and nonassessable shares of Common Stock.

                  I hereby consent to the filing of this opinion with the
Commission as Exhibit 5.2 to the Registration Statement. I also consent to the
reference to me under the caption "Legal Matters" in the Registration Statement.
In giving this consent, I do not thereby admit that I am included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

          authorized capital stock of the Corporation of any class or series,
          or bonds, certificates of indebtedness, debentures or other
          securities convertible into or exchangeable for stock of the

          pursuant to resolution of the Board of Directors to such persons,
          firms, corporations or associations, whether such holders or others,
          and upon such terms as may be deemed advisable by the Board of
          Directors in the exercise of its sole discretion.

          (e) The relative powers, preferences and rights of each series of
          Preferred Stock in relation to the relative powers, preferences and

          or resolutions adopted pursuant to authority granted in section (b) of
          this Article FOURTH and the consent, by class or series vote or

          are from time to time outstanding shall not be required for the
          issuance by the Board of Directors of any other series of Preferred
          Stock whether or not the powers, preferences and rights of such other
          series shall be fixed by the Board of Directors as senior to, or on a
          parity with, the powers, preferences and rights of such outstanding
          series, or any of them; provided, however, that the Board of Directors
          may provide in the resolution or resolutions as to any series of
          Preferred Stock adopted pursuant to section (b) of this Article FOURTH
          that the consent of the holders of a majority (or such greater

          such series voting thereon shall be required for the issuance of any
          or all other series of Preferred Stock.

          (f) Subject to the provisions of section (e), shares of any series of
          Preferred Stock may be issued from time to time as the Board of
          Directors of the Corporation shall determine and on such terms and for
          such consideration as shall be fixed by the Board of Directors.

          (g) Shares of Common Stock may be issued from time to time as the
          Board of Directors of the Corporation shall determine and on such
          terms and for such consideration as shall be fixed by the Board of
          Directors.

          (h) The authorized amount of shares of Common Stock and of Preferred
          Stock may, without a class or series vote, be increased or decreased
          from time to time by the affirmative vote of the holders of a majority
          of the stock of the Corporation entitled to vote thereon.

          FIFTH: - (a) The business and affairs of the Corporation shall be
          conducted and managed by a Board of Directors. The number of directors
          constituting the entire Board shall be not less than five nor more
          than twenty-five as fixed from time to time by vote of a majority of
          the whole Board, provided, however, that the number of directors shall
          not be reduced so as to shorten the term of any director at the time
          in office, and provided further, that the number of directors
          constituting the whole Board shall be twenty-four until otherwise
          fixed by a majority of the whole Board.

          (b) The Board of Directors shall be divided into three classes, as
          nearly equal in number as the then total number of directors
          constituting the whole Board permits, with the term of office of one
          class expiring each year. At the annual meeting of stockholders in
          1982, directors of the first class shall be elected to hold office for
          a term expiring at the next succeeding annual meeting, directors of
          the second class shall be elected to hold office for a term expiring
          at the second succeeding annual meeting and directors of the third
          class shall be elected to hold office for a term expiring at the third
          succeeding annual meeting. Any vacancies in the Board of Directors for
          any reason, and any newly created directorships resulting from any
          increase in the directors, may be filled by the Board of Directors,
          acting by a majority of the directors then in office, although less
          than a quorum, and any directors so chosen shall hold office until the
          next annual election of directors. At such election, the stockholders
          shall elect a successor to such director to hold office until the next
          election of the class for which such director shall have been chosen
          and until his successor shall be elected and qualified. No decrease in
          the number of directors shall shorten the term of any incumbent
          director.

          (c) Notwithstanding any other provisions of this Charter or Act of
          Incorporation or the By-Laws of the Corporation (and notwithstanding
          the fact that some lesser percentage may be specified by law, this
          Charter or Act of Incorporation or the ByLaws of the Corporation), any
          director or the entire Board of Directors of the Corporation may be
          removed at any time

          prepaid, to the Secretary of the Corporation not less than 14 days nor
          more than 50 days prior to any meeting of the stockholders called for
          the election of directors; provided, however, that if less than 21
          days' notice of the meeting is given to stockholders, such written
          notice shall be delivered or mailed, as prescribed, to the Secretary
          of the Corporation not later than the close of the seventh day
          following the day on which notice of the meeting was mailed to
          stockholders. Notice of nominations which are proposed by the Board of
          Directors shall be given by the Chairman on behalf of the Board.

          (e) Each notice under subsection (d) shall set forth (i) the name,
          age, business address and, if known, residence address of each nominee
          proposed in such notice, (ii) the principal occupation or employment
          of such nominee and (iii) the number of shares of stock of the
          Corporation which are beneficially owned by each such nominee.

          (f) The Chairman of the meeting may, if the facts warrant, determine
          and declare to the meeting that a nomination was not made in
          accordance with the foregoing procedure, and if he should so
          determine, he shall so declare to the meeting and the defective
          nomination shall be disregarded.

          (g) No action required to be taken or which may be taken at any annual
          or special meeting of stockholders of the Corporation may be taken
          without a meeting, and the power of stockholders to consent in
          writing, without a meeting, to the taking of any action is
          specifically denied.

          however, that any such additional By-Laws, alterations or repeal may
          be adopted only by the affirmative vote of the holders of two-thirds
          or more of the outstanding shares of capital stock of the Corporation
