Item 1. Business

General

      Priceline.com Incorporated ("priceline.com," the "Company," "we," "us" or
"our") 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 Own Price(sm) - 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 priceline.com can
fulfill the customer's offer. 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 believes that its unique business model can be applied to a
broad range of products and services. The Company 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. Priceline.com's strategy is to increase its
revenues in existing products and services by improving product offerings,
expand its Name Your Own Price(sm) service to new products and services and
offer its services in international markets through investments in independent
licensee companies.

      Priceline.com commenced its service on April 6, 1998 with the sale of
leisure airline tickets and at December 31, 1999 offered services for leisure
airline tickets, hotel rooms, mortgages and new automobiles. In December 1999
and February 2000, the Company launched two different rental car offerings. In
the near term, the Company intends to launch a Name Your Own Price(sm) service
for international and domestic long distance service. In addition, the Company's
licensee, Priceline WebHouse Club, Inc., launched a Name Your Own Price(sm)
service for groceries in the fourth quarter of 1999. Another licensee,
Priceline Perfect Yard Sale, Inc., launched on a test basis in the first quarter
of 2000 a consumer-to-consumer based Name Your Own Price(sm) service for the
sale of quality used goods over the Internet.

      For the year ended December 31, 1999, priceline.com had revenues of $482.4
million. The revenues for the year ended December 31, 1999 were comprised
primarily of: (1) transaction revenues representing the selling price of airline
tickets and hotel rooms; (2) fee income from adaptive marketing programs offered
in connection with priceline.com's product offerings; (3) ancillary revenues
consisting primarily of reservation booking fees and customer processing fees;
and (4) fee income from priceline.com's home financing and auto programs.

      Priceline.com was formed as a Delaware limited liability company in 1997
and was converted into a Delaware corporation in July 1998. The Company
completed its initial public offering in April 1999, and its comon stock is
listed on the Nasdaq National Market under the symbol "PCLN." Priceline.com
recently completed the relocation of its principal corporate offices from
Stamford, Connecticut to Norwalk, Connecticut.

The priceline.com Business Model

      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
<PAGE>

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 specify 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 these offers
to participating sellers or accesses participating sellers' private databases to
determine whether it can fulfill the customer's offer. 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 increase sales velocity. Priceline.com believes that
its demand collection system addresses limitations inherent in traditional
seller-driven pricing mechanisms in a manner that offers substantial benefits to
both buyers and sellers. The principal advantages of the priceline.com system
include the following:

      o     Cost Savings and Preferred Method Of Purchasing For Consumers.
            Priceline.com's Name Your Own Price(sm) demand collection system
            allows consumers to save money in a simple and compelling way.
            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, the
            Internet represents a preferred method to traditional retail
            channels.

      o     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 and product features. 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 sell products and
            services at discounted prices without cannibalizing their own retail
            sales by publicly announcing discount prices and without competing
            against their own distributors.

      o     Proprietary Seller Networks. Priceline.com assembles proprietary
            networks of industry leading sellers that represent high quality
            brands. 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.

      o     Guaranteed Consumer Demand For Sellers. Each customer who makes an
            offer through priceline.com must guarantee his or her 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.

      o     Broad Applications Across Multiple Markets. In contrast to many
            e-commerce companies that are building brands in vertical categories
            or groups of related categories, priceline.com believes that its
            e-commerce business model has horizontal application to products and
            services in a wide range of industries. Priceline.com further
            believes that the broad applicability of the priceline.com service
            and the strength of the priceline.com brand afford it the
            opportunity to obtain substantial economies of scale and offer the
            potential for priceline.com to become a major new channel of
            distribution.

The priceline.com Strategy

      Priceline.com's objective is to continue to expand the priceline.com
business and to operate 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:


                                       2
<PAGE>

      o     Strengthen the priceline.com Brand. The Company intends to expand
            consumer recognition of 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 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 Own Price(sm) proposition to a broad range of products and
            services. See "- Marketing and Brand Awareness."

      o     Leverage the priceline.com Brand Over Numerous Products and
            Services. Priceline.com intends to continue 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 across a broad range of products and
            services. 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. Priceline.com
            intends to expand directly in certain vertical markets and license
            its business model and name to independent licensees in other
            markets. Priceline.com and its licensees have launched or expanded
            offerings in several new categories over the past twelve months and
            these efforts will continue. See "- Products and Services."

      o     Enhance Site Functionality and Increase Consumer Usage.
            Priceline.com intends to continue 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.

      o     Pursue International Expansion. Priceline.com believes that the
            international scope of the Internet and the global demand for the
            types of products and services available through priceline.com
            presents opportunities to expand its service internationally.
            Priceline has announced initiatives in Australia/New Zealand and
            Asia and intends to pursue additional overseas opportunities. See "-
            Products and Services - International Expansion."

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, rental cars and home financing
services. Priceline.com also intends to expand its product offerings to include:
other leisure travel products such as cruises; time shares and vacation
packages; pre-paid long distance and other telecommunications services; credit
cards; and automobile, personal insurance and other financial services products.
In addition, priceline.com has announced initiatives to expand the priceline.com
service internationally.

      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 to a total of 10 domestic
airlines and 20 international airlines.

      Consumers can make offers to purchase airline tickets through the
priceline.com Web site or the 1-800-PRICELINE(sm) call center. The vast majority
of all airline ticket requests are made through priceline.com's Web site. To
make an offer, a customer specifies (1) the origin and destination of the trip,
(2) the dates on which the customer wishes to depart and return, (3) the price
the customer is willing to pay and (4) the customer's valid credit card to
guarantee the offer. When making an offer, consumers must agree to:

            o     fly on any major full-service airline;

            o     leave at any time of day between 6 a.m. and 10 p.m.on their
                  desired dates of departure and return;

            o     purchase only round trip economy class tickets between the
                  same two points of departure and return;

            o     accept at least one stop or connection;

            o     receive no frequent flier miles or upgrades; and

            o     accept tickets that cannot be refunded or changed.

      When priceline.com receives an offer, it determines whether to fulfill the
offer based upon the available fares, rules and inventory provided to
priceline.com by its participating airlines. A customer is notified whether his
or her offer has been accepted within one hour. If priceline.com is able to
obtain an airline ticket within the parameters specified by the customer, the
customer's offer is accepted and his or her credit card is charged the offer
price, plus applicable taxes, surcharges and standard processing fees, and the
ticket is delivered to the customer by the delivery method specified by the
customer. As with pricelines.com's other travel products, once a customer's
offer for airline tickets is accepted, that offer cannot be withdrawn or
cancelled.

      Hotels. In October 1998, priceline.com launched its Name Your Own
Price(sm) travel service for hotel room reservations. Priceline.com's hotel room
reservation service currently is 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 as well as several important real estate investment trusts and
independent property owners. Hotels participate by filing private discounted
rates with related inventory control rules in priceline.com's private database
in a central 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


                                       4
<PAGE>

area within a designated "class" of service (1, 2, 3, 4 or 5-star) and must
accept limitations on changes and cancellations. As with the airline ticket
service, the target market for priceline.com's hotel room reservation service is
the leisure travel market.

      Rental Cars. Priceline.com offers two different rental car services. In
December 1999, priceline.com launched its Insiders Rates(sm) service and, in
February 2000, priceline.com launched its Name Your Own Price(sm) service.
Priceline.com's rental car services are currently available in substantially all
major United States markets. Three of the top five brand name rental car
companies in the United States are seller participants in priceline.com's rental
car program.

      Under priceline.com's Insiders Rates(sm) service, participating car rental
companies offer priceline.com customers who have successfully purchased an
airline ticket from priceline.com rates on car rentals in connection
with a customer's planned travel arrangements. An offer is provided to a
customer by e-mail and on priceline.com's Web site when a customer checks the
status of his or her request.

      Priceline.com's Name Your Own Price(sm) rental car service operates in a
manner similar to its airline ticket and hotel reservation services. Consumers
can access priceline.com's Web site and select where and when they want to rent
a car, what kind of car they want to rent (i.e., economy, compact, mid-size,
SUV) and the price they want to pay per-day, excluding taxes, fees and
surcharges. When priceline.com receives an offer, it determines whether to
fulfill the offer based upon the available rates, rules and inventory. A
customer is notified whether his or her offer has been accepted within one hour.
If a customer's offer is accepted, priceline.com will immediately reserve the
rental car, charge the customer's credit card and notify the customer of the car
rental company and location providing the rental car.

      Other Travel Services. Priceline.com intends to expand its products and
services within the leisure travel industry over the next two years to encompass
cruises, all-inclusive resorts, time share and vacation packages.

      Home Financing Services. Priceline.com introduced its home financing
service in January 1999. Under the terms of separate agreements with Alliance
Partners, L.P. and LendingTree, priceline.com's financing service allows
consumers to name their interest rate and points for mortgages of a specified
term, including, purchase money mortgages, refinancings and home equity loans.

      Alliance relationship. Under the terms of priceline.com's agreement with
Alliance Partners, which was entered into on March 17, 2000, priceline.com
provides advertising and marketing support and a license of certain
priceline.com intellectual property to a newly formed indirect subsidiary of
Alliance Partners. This Subsidiary conducts business as a broker and/or lender
of residential mortgage loans under the name "pricelinemortgage." Pursuant to an
intellectual property license from priceline.com, pricelinemortgage utilizes the
priceline.com Name Your Own Price(sm) business model. Pricelinemortgage is
controlled by First Alliance Bank, a federally chartered savings association
supervised by the Office of Thrift Supervision and a wholly owned subsidiary of
Alliance Partners. Pricelinemortgage has access to the management resources and
expertise of Alliance Partners and its affiliates, including Alliance Mortgage
Company, a residential mortgage lender since 1962. Alliance Partners provides
management services to pricelinemortgage, including the procurement of personnel
and office space and assistance in obtaining regulatory approvals.
Pricelinemortgage is operating in all 50 states.


                                       5
<PAGE>

      LendingTree relationship. 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 the priceline.com Web site to multiple mortgage lending institutions for
consideration. There are currently more than 30 lenders participating in the
home financing services through LendingTree.

      To obtain a home mortgage, refinancing or home equity loan, 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. Customers
complete a simplified loan application as part of the process of making an
offer. In connection with making an offer, customers are required to guarantee
with a major credit card the payment of a good-faith deposit of $200 that is
applied towards closing costs. Priceline.com notifies a customer within six
hours whether his or her offer has been accepted by a participating lender.
Participating lenders may submit counteroffers through Priceline.com for up to
one business day following the customer's offer.

      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 cards and credit card balance
consolidations and automobile and life insurance policies. As with its other
products and services, priceline.com may expand its financial services products
by entering into licensing transactions or strategic relationships with leading
industry participants.

      New Car Sales

      Priceline.com introduced its new car sales service on a test basis in the
New York metropolitan area in July 1998. Since that time, priceline's new
automobile service has been expanded to include 26 states and the Company
intends to continue domestic expansion, subject to resolution of any regulatory
issues.


                                       6
<PAGE>

      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.

      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.
Priceline.com facilitates the exchange of customer offers and dealer acceptances
or counteroffers. Priceline.com does not negotiate on behalf of customers or
dealers and does not represent to its customers or dealers that it is acting as
an agent or broker on behalf of either party.

      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 from that dealer. In most states, when a sale is
completed, priceline.com is paid a $50 fee from the customer and a $200 fee from
the selling dealer. In other states, the Company does not currently receive
compensation from the customer or dealer as a result of regulatory restrictions.
If the customer fails to consummate the transaction within a specified time
period after being notified that an offer is accepted, the customer is charged a
cancellation fee.

      The priceline.com new car sales service is differentiated from other
Internet car sales services, which serve as lead generators for participating
car dealers. Under such services, multiple dealers may contact the customer in
response to the customer's inquiry to the Internet service. By contrast,
priceline.com's new car sales service does not reveal the identity of the
customer to the auto dealer until the dealer has accepted the customer's offer.
Furthermore, in contrast to other Internet car sales services, dealers are not
currently required to pay a participation fee to review offers from the
priceline.com service.

      Long Distance Service. In the near term, the Company intends to launch a
Name Your Own Price(sm) service for international and domestic long distance
calls. The Company intends to allow consumers to name their own price for
phone-to-phone international and domestic long distance calls.

      Licensees

      WebHouse Club. The Company has licensed its patented Name Your Own
Price(sm) business model and affiliated trademarks and software systems to
Priceline WebHouse Club, Inc., which operates an Internet-based service for

the outstanding capital stock of WebHouse Club and the balance is owned by
certain institutional and individual investors. Priceline.com owns a warrant
that entitles it to purchase up to 137.5 million shares of common stock of
WebHouse Club, or 77.5% of the fully diluted equity of WebHouse Club, at an
exercise price of $3.00 per share, upon the satisfaction of certain conditions.
Unless and until that warrant is exercised, WebHouse Club and its financial
results will not be included in priceline.com's financial statements. In
connection with the WebHouse Club transaction, Walker Digital, granted to
priceline.com an exclusive (in the field of retail commerce other than vending
machines or restaurants) worldwide license to certain intellectual property,
including patent and patent applications, useful in WebHouse Club's business.
The Company exclusively sublicensed these intellectual property rights to
WebHouse Club and granted to WebHouse Club an exclusive worldwide license to its
buyer-driven commerce patent rights and other intellectual property for use in

buyer-driven commerce for the sale, by retailers, of other products or services.
WebHouse Club pays priceline.com a sliding scale royalty descending from 1.0% of
net revenues. In addition to the patent and technology license, priceline.com
and WebHouse Club share certain information technology infrastructure, and
priceline.com provides WebHouse Club with marketing and information technology
services.

      Perfect Yard Sale. Priceline.com also has licensed its patented Name Your
Own Price(sm) business model and affiliated trademarks to Priceline Perfect Yard
Sale, Inc., a subsidiary of Walker Digital which operates a consumer-to-consumer
service for the sale of quality used goods over the Internet. Walker Digital has
agreed to grant priceline.com an exclusive, worldwide license to certain
intellectual property including patents useful in Perfect Yard Sale's business.
Under the terms of a preliminary agreement between priceline.com and Perfect
Yard Sale, priceline.com granted to Perfect Yard Sale an exclusive royalty-free
license to certain intellectual property licensed by Walker Digital to
priceline.com, as well as to the priceline.com buyer-driven commerce patent
rights and related intellectual property, and the Priceline name and associated
trademarks for use in Perfect Yard Sale's business, and agreed to provide
related services on a royalty-free basis pending execution of definitive
documentation. Under the terms of the Perfect Yard Sale preliminary agreement,
priceline.com has the right to receive a warrant to purchase a majority of the
outstanding voting equity of Perfect Yard Sale on mutually agreed upon terms.
Until that warrant is exercised, Perfect Yard Sale and its financial results
will not be included in priceline.com's financial statements.

      International Expansion

      On February 29, 2000, priceline.com announced that it had entered into
definitive agreements, to introduce priceline.com's buyer-driven e-commerce
system to the residents of Australia and New Zealand. This service will be
offered by a newly formed entity, MyPrice PTY Ltd ACN. Upon consummation of the
transactions contemplated by the definitive agreements, which is subject to
receipt of required Australian regulatory approvals, the outstanding equity of
MyPrice will be owned by a consortium of Australian and international business
executives and investors. MyPrice initially will offer leisure airline tickets
and intends to expand into other areas, including hotels, rental cars, financial
services (including credit cards, loans and insurance), telecommunications and
automotive sales. Upon consummation of the transactions, priceline.com will
license its business model to MyPrice and will receive an annual licensing
payment from MyPrice. Priceline.com will purchase a convertible note allowing it
to take a 50% interest in MyPrice under certain conditions. Unless and until
that note is converted, MyPrice and its financial results will not be included
in priceline.com's financial statements. MyPrice expects to launch two web sites
later this year - MyPrice.com.au and MyPrice.com.nz (both powered by
priceline.com).

      On January 26, 2000, the Company announced that it had entered into an
agreement in principle to form an alliance with Hutchison Whampoa Limited to
introduce priceline.com's buyer-driven e-commerce system to 2.6 billion
consumers in China (and Hong Kong), India, Taiwan, Indonesia, Singapore,
Thailand, Korea, Malaysia, the Philippines, Vietnam and certain other Asian
countries. Under the terms of the agreement in principle between priceline.com
and a subsidiary of Hutchison, upon execution of mutually acceptable definitive
agreements, a new company will be created to launch and manage the Name Your Own
Price(sm) service in Asia. The Company will license its business model to the
newly created company and provide technology, marketing and operations support.
Hutchison will contribute its strong brand and leverage its extensive customer
base and retail network in Asia. The new company will pay priceline.com an
annual licensing fee in respect of priceline.com's intellectual property and
technology marketing and operation services fees. In addition, Priceline.com
will purchase a convertible note allowing it to take up to a 50% interest in the
new company under certain conditions. Unless and until that note is converted,
the new company and its financial results will not be included in
priceline.com's financial statements. Hutchison will also purchase equity
securities in the new company and is also providing management services. The new
company is expected to launch its first service for leisure airline tickets
later this year completion of the transaction is subject to negotiation and
execution of definitive agreements and certain other conditions.

      Priceline.com is continuing to pursue additional opportunities to expand
its service internationally.

Adaptive Marketing Programs


                                       8
<PAGE>

      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's adaptive marketing programs 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 a round-trip airline ticket can immediately have the amount of his or her
offer increased (and thereby increase his or her likelihood of success) by
applying online for a credit card.

      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 marginally 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 priceline.com.

      During 1999, priceline.com added adaptive marketing partners and, as a
result, reduced its dependence on any one partner. 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.

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

Marketing and Brand Awareness

      Priceline.com has established itself as a leading e-commerce brand through
an aggressive marketing and promotion campaign. During fiscal year 1999,
priceline.com incurred $79.6 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 television, 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.

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:

            o     Internet travel agents such as Microsoft's Expedia;

            o     traditional travel agencies;


                                       9
<PAGE>

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

            o     individual or groups of airlines, hotels, rental car
                  companies, cruise operators and other travel service
                  providers; and

            o     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:

            o     banks and other financial institutions;

            o     online and traditional mortgage and insurance brokers,
                  including mortgage.com, Quicken Mortgage, E-Loan and iOwn,
                  Inc.; and

            o     insurance companies.

      Priceline.com's current or potential competitors with respect to rental
cars include, among others, rental car companies and traditional and online
travel agencies and travel service providers.

      With respect to long distance services, priceline.com's potential
competitors include long distance providers, local exchange providers that may
be entering the long distance market and Internet Protocol telephone services.

      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 or
offline companies. Other large companies with strong brand recognition,
technical expertise and experience in Internet commerce could also seek to
compete with priceline.com. The Company also believes that a number of airlines
intend to invest in and offer discount airfares and travel services through a
site or sites to be established and similar steps may be under consideration by
certain hotel companies and travel service providers. 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: (1) marketing and promotional campaigns, (2)
attracting traffic to their Web sites, (3) attracting and retaining key
employees, (4) securing vendors and inventory and (5) 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 priceline.com
operates. These include large global inventory systems, such as airline and
hotel room 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 Norwalk,
Connecticut, Boston, Massachusetts, Columbus, Ohio, and Salt Lake City, Utah.

      Priceline.com's systems infrastructure, Web and database servers are
hosted at Exodus Communications, Inc. in Jersey City, New Jersey, which provides
communication lines from multiple providers including UUNet and AT&T, as well as
24-hour monitoring and engineering support. Exodus has its own generator and
multiple back-up systems in Jersey City. Priceline.com also maintains an
uninterruptible power supply system and generator and redundant servers at its
Stamford, Connecticut site to provide service capability if the Exodus site
fails.

      Priceline.com also offers phone service through its toll-free number,
1-800-PRICELINE(sm), 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 currently holds four issued United States patents, Nos.
5,794,207, 5,797,127, 5,897,620 and 6,041,308, over 25 pending United States
patent applications and corresponding pending international patent applications.
Priceline.com files additional patent applications on new inventions, as
appropriate.

      While priceline.com believes that its issued patents and pending patent
applications help to protect the priceline.com business, there can be no
assurance that

            o     any patent can be successfully defended against challenges by
                  third parties;

- --------


                                       11
<PAGE>

            o     the pending patent applications will result in the issuance of
                  patents;

            o     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 patents or patent applications;

            o     because of variations in the application of our business model
                  to each of our products and services, our patents will 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;

            o     new prior art will not be discovered which may diminish the
                  value of or invalidate an issued patent; or

            o     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.

      There has been recent discussion in the press regarding the examination
and issuance of so called "business-method" patents. As a result, the United
States Patent and Trademark Office has indicated that it intends to intensify
the review process applicable to such patent applications. The new procedures
are not expected to have a direct effect on patents already granted.
Priceline.com can not anticipate what affect, if any, the new process will have
on the Company's pending patent applications.

      Priceline.com has been notified that a third-party patent applicant has
challenged its U.S. Patent No. 5,794,207 patent by attempting to provoke an
interference action in the United States Patent and Trademark Office. See "-
Legal Proceedings."

      Walker Digital owns certain intellectual property rights associated with
the business of WebHouse Club that have been licensed exclusively to
priceline.com in the field of buyer-driven commerce (other than vending machines
or restaurants) which, in turn, sublicensed such rights to WebHouse Club for use
in its business. Walker Digital also owns certain intellectual property rights
associated with the business of Perfect Yard Sale. In a preliminary agreement,
Walker Digital has agreed to license such rights exclusively to priceline.com in
the field of buyer-driven commerce which, in turn, will be sublicensed to
Perfect Yard Sale for use in its business. See "- Products and Services -
Licensees."

      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. 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 "- Additional Factors That May Affect
Future Results -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" in
the United States. Domain names are generally regulated by Internet regulatory
bodies. The relationship between trademark and similar laws and domain name
registration is evolving, including passage during 1999 of the
Anti-Cybersquatting Consumer Protection Act, which significantly enhances the
ability to prevent incorporation by third parties of trademarks into domain
names. Priceline.com actively pursues infringers who improperly incorporate its
trademarks into domain names, as appropriate, to maintain and enhance the
strength of its trademarks. See "- Additional Factors That May Affect Future
Results - Our Success Depends On Our Ability To Protect Our Intellectual
Property."

Governmental Regulation

      The products and services provided by the Company are subject to various
federal, state and local regulations. For example, the Company's travel service
is subject to laws governing the offer and/or sale of travel services as well as
laws requiring the Company to register as a "seller of travel." With respect to
the Company's new car sales service, the Company is subject to regulations
governing the registration and conduct of automobile dealers and brokers. In
connection with the Company's plans to expand its new car sales service
domestically, the Company may be required to register as an automobile
dealer/broker in each applicable jurisdiction. However, the Company may be
unable to expand to those jurisdictions that require dealer/brokers to maintain
a dealer lot zoned for automobiles, obtain a franchise agreement with automobile
manufacturers, or other related requirements. The Company will consider
variations to its business model to address regulatory issues or offer its
services without compensation pending resolution of any regulatory issues.

      The Company is also subject to laws governing the licensing and conduct of
persons providing mortgage brokerage services. Such laws typically require
certain consumer protection disclosures and loan solicitation procedures. For
example, the Real Estate Settlement Procedures Act prohibits the payment and
receipt of mortgage loan referral fees, and permit persons to be compensated
only for the fair market value of non-referral services. Accordingly, the
Company has structured its home financing services such that it provides
non-referral services such as Web site development and advertising to a licensed
mortgage broker who, in turn, provides the back-end processing of the loan
referrals. Although the mortgage broker compensates the Company only for the
fair market value of its non-referral services, it is possible that governmental
authorities could scrutinize the compensation agreement under the Real Estate
Settlement Procedures Act or enact new legislation that might limit or prohibit
the Company's present arrangement.

      All of the Company's services are subject to federal and state consumer
protection laws and regulations prohibiting unfair and deceptive trade
practices. The Company is also subject to regulations applicable to businesses
conducting online commerce. Today there are relatively few laws specifically
directed toward online services. However, due to the increasing popularity and
use of the Internet and online services, it is possible that laws and
regulations will be adopted with respect to the Internet or online services.
These laws and regulations could cover issues such as online contracts, user
privacy, freedom of expression, pricing, fraud, content and quality of products
and services, taxation, advertising, intellectual property rights and
information security. Applicability to the Internet of existing laws governing
issues such as property ownership, copyrights and other intellectual property
issues, taxation, libel, obscenity and personal privacy is uncertain, but any
such new legislation could have a material adverse effect on the Company's
business, operating results and financial condition. In addition, some states
may require the Company to qualify in that state to do business as a foreign
corporation because the Company's service is available in that state over the
Internet. Although the Company is qualified to do business in a number of
states, failure to meet the qualifications of certain states could subject the
Company to taxes and penalties.

      As the Company expands its international presence, it will also be subject
to various foreign regulations and governing bodies that might limit the
Company's products and services. Likewise, the Company may be subject to
unexpected changes in regulatory requirements and various tariffs and trade
barriers in connection with online commerce. While the Company's licensees will
generally be responsible for complying with applicable regulations, any failure
on their part to comply may have an adverse effect on the Company.

Employees

      As of March 10, 2000, the Company employed approximately 373 full-time
employees. Priceline.com also employs independent contractors to support its
customer service and system support functions.

<PAGE>

      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.

Additional Factors That May Affect Future Results

      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:

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

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

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

            o     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

      As of December 31, 1999, we had an accumulated deficit of $1.18 billion,
of which $1.07 billion related to certain non-cash charges arising from equity
issuances to a number of participating airlines, our chief executive officer and
other parties, which was partially offset by $188.8 million of income
representing the amount of estimated fair value of warrants received by us in
connection with our relationship with our licensee WebHouse Club. We have not
achieved profitability and expect to continue to incur losses. The principal
causes of our losses are likely to continue to be significant brand development
costs, marketing, personnel 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. 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.

      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,
significantly increased costs that we may incur in connection with adaptive
marketing programs, reductions in fees paid to us


                                       14
<PAGE>

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.

      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, or if additional adaptive marketing programs will be initiated. If
such programs 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 relatively unproven business model, we cannot
predict our future revenues or results of operations accurately. It is likely
that in one or more future quarters our operating results will fall below the
expectations of securities analysts and investors. If this happens, the trading
price of our common stock would almost certainly be materially and adversely
affected.

      Our business has no backlog and almost all of our 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, less excess
airline ticket inventory would be available to priceline.com. 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 a substantial majority of total revenue for the year ended
December 31, 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 six largest airline
suppliers accounted for approximately 93% of airline ticket revenue for
the year ended December 31, 1999. As a result, currently we are substantially

- --------


                                       15
<PAGE>

dependent upon the continued participation of these airlines in the
priceline.com service in order to maintain and continue to grow our total
airline ticket revenues. We currently have 30 participating airlines. However,
our airline participation agreements:

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

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

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

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

            o     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.

      Our agreement with Delta contains certain restrictions relating to the
terms of participation in our service by other carriers and the circumstances
under which we may transfer or license our intellectual property to other travel
providers. 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.

      Our Business Model is Novel and Relatively Unproven

      The priceline.com service is based on a novel and relatively 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


                                       16
<PAGE>

collection system over the Internet. Therefore, it is impossible to predict the
degree to which consumers and sellers will use the priceline.com service.

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

      We Need to Sell New Products and Services

      We are unlikely to make significant profits unless we continue to make new
or complementary products and services and a broader range of existing products
and services available through the priceline.com service or through services
provided by our licensees. We will incur substantial expenses and use
significant resources in trying to continue to expand the type and range of the
products and services that we offer. However, we may not be able to attract
sellers, other participants and licensees to provide such products and services
or consumers to purchase such products and services through the priceline.com
service. In addition, if we or our licensees launch new products or services
that are not favorably received by consumers, our reputation and the value of
the priceline.com brand could be damaged.

      The great majority 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, hotel room reservation or rental
car reservation has no value. The expiring nature of the inventory creates
incentives for airlines, hotels and rental car companies to sell seats, hotel
room reservations or rental car 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.

      New Businesses We Are Evaluating May Not Be Successful

      We intend to expand our current Name Your Own Price(sm) business model
into other areas of e-commerce and to other regions, directly and through
licensees. We recently licensed our name and business model to WebHouse Club, a
privately held independent start-up company affiliated with Walker Digital for
use in a business that enables consumers to use the Internet to identify the
purchase terms for groceries and other retail merchandise which they would
subsequently pick up from participating retailers. We also recently entered into
a similar preliminary licensing arrangement with Perfect Yard Sale, another
privately held independent start-up company affiliated with Walker Digital for
use in a consumer-to-consumer business in which buyers would make conditional
purchase offers to acquire goods from other consumers. In addition, we have
licensed our name and business model to Alliance Partners in connection with our
home financing services. We also have entered into, and intend to continue to
enter into, similar licensing arrangements with third parties in connection with
international expansion of the priceline.com service. These new businesses
typically incur start-up costs and operating losses and, 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 need to service these licensees, our core
business may suffer. Moreover, expansion of our core business model will expose
us to additional risks not currently applicable to our existing operations. The
additional risks associated with the expansion of our core business could have a
material adverse effect on our business generally. In addition, as we expand our
business model to other areas of e-commerce, these new businesses will face
competition from established providers in those areas.

      We May Be Unable to Effectively Manage Our Rapid Growth


                                       17
<PAGE>

      We have rapidly and significantly expanded our operations and anticipate
that further expansion will be required to realize our growth strategy. Our
rapid growth has placed significant demands on our management and other
resources which, given our expected future growth rate, is likely to continue.
To manage our future growth, we will need to attract, hire and retain highly
skilled and motivated officers and employees and improve existing systems and/or
implement new systems for: (1) transaction processing; (2) operational and
financial management; and (3) training, integrating and managing our growing
employee base.

      If We Lose Our Key Personnel or Cannot Recruit Additional Personnel, Our
      Business May Suffer

      Competition for personnel with experience in Internet commerce is intense.
If we do not succeed in attracting new employees or retaining and motivating our
current and future employees, our business could suffer significantly.

      Since our formation in July 1997, we have expanded from 10 to 373
full-time employees as of March 10, 2000. We also have employed many key
personnel since our launch in April 1998, including our Chairman and Chief
Executive Officer, our President and Chief Operating Officer, our Senior
Executive Vice President Stategy, Planning and Administration and Chief
Financial Officer, our Executive Vice President and General Counsel, our
Executive Vice President and Chief Marketing 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:

            o     our ability to retain and motivate our senior management and
                  other key employees; and

            o     our ability to identify, attract, hire, train, retain and
                  motivate other highly skilled technical, managerial, marketing
                  and customer service personnel.

      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. Any interruption in these third-party services, or a deterioration
in their performance, could be disruptive to our business. Our agreements with
third-party service providers 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. See "- Competition."

      Our Success Depends on Our Ability to Protect Our Intellectual Property


                                       18
<PAGE>

      We have developed what we believe is 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. See "-
Intellectual Property" and "Legal Proceedings."

      Legal Proceedings

      We have received a copy of a Petition for Interference that requests the
United States Patent and Trademark Office to declare an "interference" between a
patent filed by a third party describing an electronic market for used and
collectible goods and our U.S. Patent No. 5,794,207. We also are a party to
other legal proceedings described in Item 3 - "Legal Proceedings." An adverse
outcome in any of the actions described in Item 3 could have a material adverse
effect on our business. See "Legal Proceedings."

      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 widespread 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.

      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.

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:

o     unanticipated disruptions in service;

o     slower response times;

o     decreased customer service and customer satisfaction; or

o     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, we do not have fully
redundant systems, a formal disaster recovery plan or alternative providers of
hosting services. In addition, we do not carry sufficient business interruption
insurance to compensate for losses that could occur. Any system failure that
causes an interruption in service or decreases the responsiveness of the
priceline.com service could impair our reputation, damage our brand name and
materially adversely affect our revenues.

      We May Not Be Able to Keep Up with 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,


                                       19
<PAGE>

networking or telecommunications technologies or other technological changes
could require us to incur substantial expenditures to modify or adapt our
services or infrastructure.

      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 significant
interruptions in our operations. For instance, several major Web sites recently
experienced significant interruptions as a result of improper direction of
excess traffic to those sites. 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:

      o     quarterly variations in our operating results;

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

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

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

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

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

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

      o     changes in the status of our intellectual property rights;

      o     lack of success in the expansion of our business model horizontally
            or geographically;

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


                                       20
<PAGE>

      o     additions or departures of key personnel; and

      o     stock market price and volume fluctuations.

      Sales of a substantial number of shares of our common stock 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.

      In addition, the trading prices of Internet stocks in general, including
ours, have experienced extreme price and volume fluctuations. 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.

      Our Business is Subject to Tax Uncertainties

      Potential Federal Air Transportation Tax on Airline Ticket Sales. A
Federal transportation tax is imposed upon the sale of airline tickets. The tax
is based on a percentage of the cost of transportation, which was 9% for periods
prior to October 1, 1998, 8% for the period October 1, 1998 through September
30, 1999 and 7.5% thereafter. The Company has historically interpreted the tax
regulations as requiring that the tax be computed based on the amount charged by
the airline to the Company for the airline ticket and the Company's
participating airlines have collected and remitted the tax based on this amount.
The Company applied for a ruling from the Internal Revenue Service confirming
this interpretation. In December 1999, the Internal Revenue Service indicated to
the Company that it was unlikely that a favorable ruling would be issued. The
Company subsequently withdrew its ruling request because of the uncertainty of
the outcome. Because the Company anticipated the possibility of an adverse
ruling on this issue, the Company accrued approximately $1.9 million relating to
the balance of the tax liability for tickets sold prior to that date. The
Company believes this accrual to be adequate, but there can be no assurance as
to the final outcome because a formal ruling has not been issued by the Internal
Revenue Service.

      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 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


                                       21
<PAGE>

taxes on Internet-based commerce. The imposition of such taxes could adversely
affect our ability to become profitable.

      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. See
"-Government Regulation."

Item 3. Legal Proceedings

      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 and
priceline.com's U.S. Patent No. 5,794,207. Priceline.com currently is awaiting
information from the Patent Office regarding whether it will initiate an
interference proceeding.

      On January 19, 1999, Marketel International Inc., a California
corporation, filed a lawsuit against priceline.com, 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, among other things, that the
defendants conspired to misappropriate Marketel's business model, which
allegedly was provided in confidence approximately ten years ago. The amended
complaint also alleges that four former Marketel employees are the actual sole
inventors or co-inventors of U.S. Patent No. 5,794,207 which was issued on
August 11, 1998 and has been assigned to priceline.com. Marketel asks that the
patent's inventorship be corrected accordingly.

      On February 5 and February 10, 1999, the Company filed its answer and
amended answer, respectively, to the amended complaint, in which it denied the
material allegations of liability in the complaint. The cause of action is
currently pending against priceline.com and Priceline Travel, Inc. under the
caption Marketel International, Inc. v. Priceline.com, et al., No. C-99-1061
(N.D. Cal. 1999). 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. 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.

      On October 13, 1999, priceline.com filed a complaint in the United States
District Court for the District of Connecticut under the caption Priceline.com
Incorporated v. Microsoft Corporation and Expedia, Inc., No. 399CV1991 (AWT)
alleging that Microsoft Corporation and Expedia, Inc., a subsidiary of Microsoft
Corporation, infringe priceline.com's U.S. Patent No. 5,794,207 by operating the
defendants' "Hotel Price Matcher" service, and that the defendants' conduct
toward priceline.com violated the Connecticut Unfair Trade Practices Act. On
December 20, 1999, defendants moved the Court to dismiss the complaint for
failure to name a necessary party, Marketel. On March 21, 2000, the presiding
judge stated that he intends to deny defendants' motion to dismiss, and that a
decision will be forthcoming. On December 23, 1999, the Court granted
priceline.com's motion to supplement the complaint to expressly include
defendants' "Flight Price Matcher" service. In the lawsuit, priceline.com is
seeking declaratory relief, permanent injunctive relief and actual and punitive
damages.

      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,
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.

      The Company is unable to predict the outcome of the legal proceedings
referred to above.

Item 4. Submission of Matters to a Vote of Security Holders

      No matters were submitted for a vote of stockholders of the Company during
the fourth quarter of the year ended December 31, 1999.

Dividend Policy

      Priceline.com has not declared or paid any cash dividends on its capital
stock since its inception and does not expect to pay any cash dividends for the
foreseeable future. Priceline.com currently intends to retain future earnings,
if any, to finance the expansion of its business.

Holders

      As of March 17, 2000, there were approximately 476 stockholders of record
of priceline.com's common stock, although the Company believes that there is a
significantly larger number of beneficial owners.

Use of Proceeds of Initial Public Offering

      On April 1, 1999, priceline.com completed an initial public offering in
which it sold 10,000,000 shares of its common stock. The managing underwriters
in the offering were Morgan Stanley & Co., Incorporated, Merrill Lynch, Pierce,
Fenner & Smith Incorporated, BancBoston Stephens Inc. and Donaldson Lufkin &
Jenrette Securities Corporation. The shares of common stock sold in the offering
were registered under the Securities Act of 1933, as amended, on a Registration
Statement on Form S-1 (the "Registration Statement") (Reg. No. 333-69657) that
was declared effective by the Securities and Exchange Commission on March 29,
1999. All 10,000,000 shares of common stock registered under the Registration
Statement were sold at a price of $16.00 per share for gross proceeds of $160.0
million. Offering proceeds to priceline.com, net of approximately $11.2 million
in aggregate underwriter discounts and commissions and $4.5 million in other
related expenses, were approximately $144.3 million.

      Net offering proceeds received on April 1, 1999 from the initial public
offering were used for general corporate purposes, including working capital to
fund anticipated operating losses, expenses associated with its advertising
campaigns, brand-name promotions and other marketing efforts and capital
expenditures. Priceline.com also may use a portion of the net proceeds,
currently intended for general corporate purposes, to acquire or invest in
businesses, technologies, products or services, although no specific
acquisitions are planned and no portion of the net proceeds has been allocated
for any acquisition. None of the net offering proceeds of priceline.com have
been paid directly or indirectly to any director, officer, general partner of
priceline.com or their associates, persons owning 10% or more of any class of
priceline.com's equity securities, or an affiliate of priceline.com other than
compensation to and other related arrangements with officers of priceline.com in
the ordinary course of business and payments that were made in the ordinary
course of business to Walker Digital Corporation pursuant to a reciprocal
services arrangement.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

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

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 Own Price(SM)--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.
Consumers agree to hold their offers open for a specified period of time and,
once fulfilled, offers cannot be canceled. We benefit consumers by enabling them
to save money, while at the same time benefiting 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, we enable sellers to generate incremental
revenue without disrupting their existing distribution channels or retail
pricing structures.

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

      o     leisure airline tickets, provided by ten domestic and 20
            international airline participants;

      o     hotel rooms, which was launched in October 1998, in substantially
            all major United States markets with more than 15 leading national
            hotel chains as participants;

      o     rental cars, which was launched in December 1999, in substantially
            all major United States markets with three leading rental car chains
            as participants;

      o     new automobiles, which was launched on a test basis in the New York
            Metropolitan Area in July 1998 and is now offered in 26 states;


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

      Priceline.com also is currently planning an expansion of its core Name
Your Own Price(SM) business model to other areas of e-commerce, including long
distance telephone service, cruises and vacation packages.

      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.
During 1999, the Company increased its number of adaptive marketing partners
from one to ten, thus reducing its dependence on any one partner. 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 has announced several transactions pursuant to which third
parties ("Licensees") license the priceline.com name and demand collection
system for offering a particular product or service or for offering a number of
products or services in a distinct international region. Pursuant to the
Licensee transactions, priceline.com generally receives a royalty under the
license and may also receive fees for services and reimbursement of certain


                                       24
<PAGE>

expenses. Priceline.com also holds convertible debt or warrants entitling it to
acquire a significant percentage of such Licensee's equity securities upon the
occurrence of certain events. Unless such equity securities are converted, the
results of Licensees will not be included in priceline.com's financial results.

      In 1999, priceline.com licensed its name and demand collection system to
Priceline WebHouse Club, Inc. and agreed to provide certain services to WebHouse
Club. WebHouse Club offers a Name Your Own Price(SM) service for groceries and
has announced the planned offering of a service for gasoline. Under the
negotiated agreements, priceline.com receives a royalty based on a percentage of
WebHouse Club revenues and compensation at fair value for certain services
rendered. As an inducement to enter into a relationship with WebHouse Club,
priceline.com received a warrant to purchase a majority of the shares of
WebHouse Club common stock. The warrants are non-forfeitable, fully vested upon
grant, exercisable in five years or earlier upon the occurrence of certain
events, and do not require the performance of any additional services. Upon
receipt of the warrant in the fourth quarter, priceline.com recognized $188.8
million of income representing the amount of the estimated fair value of the
warrants, based on an independent valuation.

      In March 2000, the Company entered into an agreement with Alliance
Partners, LP, pursuant to which Alliance has formed an operating subsidiary,
Priceline Mortgage, for the primary purpose of acting as a broker and/or lender
of residential mortgage loans in connection with the priceline.com mortgage
service. Priceline.com has agreed to provide $3.62 million of financing to an
affiliate of Alliance in the form of a convertible secured note and has agreed
to license the "priceline" name and business model for use by Priceline
Mortgage. Alliance has agreed to provide management services to Priceline
Mortgage, including the procurement of personnel and office space and assistance
in obtaining regulatory approvals. A pilot program was launched in early October
1999 and currently is operating in all 50 states.

      Because the priceline.com system does not set minimum offer thresholds,
and consumers are not charged to make offers for its products, it is expected
that we will receive a significant number of unreasonable or "fantasy offers".
Accordingly, in addition to analyzing our actual fulfillment rates, we also
analyze the percentage of "reasonable" offers that we are able to fill. We
consider an offer for an airline ticket, hotel room or rental car to be
"reasonable" when it is no more than 30% lower than the lowest generally
available advance-purchase fare for the same product. Using this standard, the
overall percentage of offers considered reasonable for the year ended December
31, 1999 was approximately 57.0%. The Company measures its "bind" rate as the
percentage of reasonable offers that the Company ultimately fulfills. The
Company's bind rate for 1999 was 43.6% for all reasonable airline ticket, hotel
room and rental car offers.

      When making offers for airline tickets 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. As a result of the Company's
"checkstatus" feature, introduced in April 1999, consumers whose initial
requests are not satisfied are permitted to resubmit revised offers that reflect
at least one change to their itinerary. Effective with this change, each initial
offer and any resubmitted offers are treated as a single offer for purposes of
measuring our total offer volume and our offer fulfillment rates. Previously,
each had been counted as a separate offer. Therefore, comparisons with prior
periods may not be meaningful.

      As of December 31, 1999, the Company had an accumulated deficit of $1.18
billion, of which $1.07 billion related to certain non-cash charges arising from
equity issuances to a number of participating airlines, its chief executive
officer and other parties, as more fully described below, partially offset by
the WebHouse Club warrant income described above. 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.

Priceline.com intends to continue to invest heavily in marketing and promotion,
technology and personnel. As a result, it expects to incur additional losses.
However, the Company's plans call for reduction of operating losses and
improvement in its gross margins in an effort to achieve profitability.
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.

      As of December 31, 1999, the Company had outstanding non-qualified stock
options to purchase 27,024,740 shares issued to various employees, consultants
and directors pursuant to the Company's 1997 Omnibus Plan and 1999 Omnibus Plan.
The options entitle the holders to purchase common stock at a weighted average
exercise price of approximately $13.93 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 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. The total exercise price of the options outstanding
at December 31, 1999 is $376.5 million. 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 tax payments. Such
deduction would be utilized to the extent that the Company generates taxable
income. The calculation of the payroll tax expense and income tax deduction, and
the timing of those events and the receipt of the related cash inflow, is
directly dependent upon the exercise of options and the value of shares of
priceline.com Common Stock at the time of exercise. As the decision to exercise
options is at the sole discretion of the holder of the options, the timing and
amount of the expense, income tax deduction and timing of the cash inflows
cannot be estimated.

      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 incurred a non-cash charge of approximately $88.4
million during the third quarter of 1999 representing the fair value of the
warrant on the grant date. In November 1999, the Company amended the Continental
warrant to allow the exercise price to fall within the range of the warrants
issued to other airlines discussed below. Priceline.com incurred a non-cash
charge of approximately $3.5 million during the fourth quarter as a result of
the warrant amendment.

      In August 1998, priceline.com entered into a warrant agreement granting
Delta Airlines ("Delta") the right 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 became
exercisable at the earlier of seven years or upon the achievement of certain
performance thresholds. However, the agreement did 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. Therefore, the Company
recorded a non-cash charge of approximately $58.7 million, reflecting the fair
value of the Delta warrant on December 31, 1998.

      In November 1999, the Company further amended the Delta warrant to provide
Delta with a cashless exercise right. Upon the exercise of the warrant, Delta
acquired a total of 16,525,834 shares of


                                       26
<PAGE>

Common Stock of priceline.com. In conjunction with that transaction, Delta sold
2,085,767 shares of priceline.com Common Stock to priceline.com's founder and
Vice Chairman Jay S. Walker for an aggregate purchase price of $125 million. The
Company further gave Delta the right to exchange six million shares of
priceline.com Common Stock for six million shares of newly issued convertible
preferred stock that may be converted into priceline.com Common Stock on a
one-for-one basis. To date, Delta has not elected to exercise the conversion
right.

      In November 1999, the Company entered into separate Participation Warrant
Agreements with each of eight major domestic airlines relating to their
inclusion in the Company's leisure airline ticket service. Under the
Participation Warrant Agreements, the airlines were granted warrants to purchase
a total of 20 million shares of priceline.com Common Stock at exercise prices
ranging from $52.625 to $59.933 per share. All warrants were fully vested on the
date of grant, but generally are not exercisable until November 2005, subject to
acceleration under certain circumstances. Priceline.com incurred additional
warrant costs of approximately $1.1 billion during the fourth quarter as a
result of the issuance of the warrants.

Results of Operations

      Priceline.com did not commence operations until April 1998. Accordingly,
discussion of comparisons with the prior year is not meaningful.

Revenues.......................................   $482,410    $35,237     1,269%

      Revenues for the year ended December 31, 1999 were comprised primarily of:
(1) transaction revenues representing the selling price of airline tickets,
hotel rooms and rental cars; (2) fee income from adaptive marketing programs
offered in connection with our product offerings; (3) ancillary revenues
consisting primarily of Worldspan reservation booking fees and customer
processing fees; and (4) fee income from our home financing and auto programs.

      Revenues increased during 1999 as a result of the substantial development
of our unique customer base, repeat purchases by existing customers and the
inclusion of the hotel room, rental car, automobile, and home financing services
and adaptive marketing programs. The Company has launched certain of its
services in select geographic markets and then expanded to other regions. During
1999, the Company's hotel room reservation service expanded from 25 cities to
nationwide coverage. The Company's auto program was launched in the New York
City area and expanded to cover 26 states at December 31, 1999. The Company's
rental car service was launched nationally during the fourth quarter. The
Company currently plans to launch its products for long distance telephone
services, cruises and vacation packages during 2000. The Company believes each
of these products has the potential to increase revenues in 2000.

      As of December 31, 1999 priceline.com had a base of approximately 3.8
million unique customers. A unique customer is defined as someone who has made a
guaranteed offer for at least one of priceline.com's products. Of the total
unique customer base, approximately 3.0 million made their first offer on
priceline.com during 1999. During 1999, priceline.com customers made
approximately 4.3 million offers for services.


                                       27
<PAGE>

      Ancillary revenues for the year ended December 31, 1999 increased as a
result of volume driven increases in Worldspan reservation booking fees and the
introduction of a customer processing fee in the airline and hotel services.
Fee-based income and ancillary revenues represented 8.4% of total revenues for
the year ended December 31, 1999.

      Product Costs and Gross Profit

                                                      Year Ended

Gross Profit...................................    $57,831   $(1,288)     4,590%
Gross Margin...................................      12.0%     (4.0)%

      For the year ended December 31, 1999, product costs were comprised of (1)
the cost of airline tickets from our suppliers, net of the federal air
transportation tax, segment fees and passenger facility charges imposed in
connection with the sale of airline tickets; (2) the cost of hotel rooms from
our suppliers, net of hotel tax; and (3) supplier warrant costs that represent a
non-cash expense related to the issuance of common stock warrants to one of our
airline program participants in January 1999. We anticipate that we will
recognize additional non-cash supplier warrant costs in the amount of
approximately $381,000 in each of the next four fiscal quarters.

      Gross profit is comprised of revenues less cost of revenues. Excluding the
effect of non-cash supplier warrant costs for the year ended December 31, 1999,
the Company had gross profit of $59.4 million. During 1999, gross profit was
positive as a result of the transactional sales volumes that were sold at
positive margins, and the launch of products generating fee-based revenues.
Because fee-based and ancillary revenues generally do not involve separate
costs, these revenues had a disproportionately positive impact on total gross
profit and made a substantial contribution to gross profit for the year ended
December 31, 1999.

      For the year ended December 31, 1999, gross margin increased each quarter
as a result of increased sales volume, increased fee-based revenue and decreased
sales of tickets that were sold below cost. Fee-based revenues, such as adaptive
marketing revenues, ancillary revenues and revenues from financial services and
automobiles generate higher margins than transaction revenues, on which the
gross margin generated is derived from the spread between customer payments and
product costs.

      The Company expects that gross profit and gross margin will improve in the
first quarter of 2000 as a result of anticipated consumer demand sufficient to
allow the Company to increase revenues while selling its products at increasing
positive margins. As a result of this anticipated growth, the Company expects
the proportion of its gross profit and gross margin attributable to adaptive
marketing revenues to decline.

      Warrant costs, net consist of the fair value of warrants issued to airline
suppliers during 1999, as discussed above. Such costs were partially offset by
warrant income of $188.8 million recognized in the fourth quarter as a result of
the receipt of warrants to purchase common stock of WebHouse.

operates priceline.com's call center; (4) compensation for priceline.com's sales
and marketing personnel; and (5) provisions for customer charge-backs (based
upon a percentage reflecting priceline.com's historical experience). The Company
plans to continue to invest heavily in advertising and other marketing programs
and expects that all marketing costs will increase. However, with the exception
of processing fees and provisions for customer accommodations and charge-backs,
which the Company anticipates will grow proportionately with transaction based
revenue, the Company anticipates that the other marketing costs will decrease as
a percentage of revenues as the result of anticipated revenue growth.

      General and administrative expenses for the year ended December 31, 1999
were comprised primarily of compensation for personnel, fees for outside
professionals, telecommunications and other overhead costs, including occupancy
expense. The year ended December 31, 1999 included a charge of $1,812 relating
to option payroll taxes resulting from the exercise of employee stock options.
Excluding this expense, general and administrative expense was 5.3% of sales for
the year ended December 31, 1999. Excluding this charge, general and
administrative expenses increased as a result of increased payroll and overhead
costs associated with the expansion of our product offerings and increases in
our revenue base.

% of Revenues.................................        2.9%      31.6%

      Systems and business development expenses for the year ended December 31,
1999 were comprised primarily of: (1) compensation to our information technology
and product development staff; (2) payments to outside contractors; (3) data
communications and other expenses associated with operating priceline.com's Web
site; and (4) depreciation and amortization on computer hardware and software.
During 1999, systems and business development expenses increased due to
increased payroll costs, increased depreciation and amortization resulting from
increased capital expenditures and


                                       29
<PAGE>

increased development costs associated with the expansion of priceline.com's
product offerings and technological infrastructure. As the Company depends on
its web site and internal systems to operate, it expects to continue to invest
significantly on the systems and business development area.

      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
year ended December 31, 1999, priceline.com capitalized approximately $13.9
million of computer software developed or obtained for internal use.
Amortization of such costs aggregated approximately $1.1 million during the year
ended December 31, 1999.

      Other income, net, for the year ended December 31, 1999 was primarily
comprised of interest income. Interest income on cash and marketable securities
increased due to higher cash and cash equivalent balances resulting from our
initial public offering of common stock in April of 1999 and our secondary
public offering of common stock in August of 1999.

Year Ended December 31, 1998

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

      Revenues

      Total revenues for the year ended December 31, 1998 were $35.2 million.
Since commencement of operations in April 1998, essentially all revenues
consisted of airline ticket sales, hotel room reservations and related adaptive
marketing programs. 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.

      Product Costs 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.

      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. In 1998, priceline.com
sold 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 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

      Warrant Cost, net. Warrant costs, net 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 the airline's participation in the priceline.com service.

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

      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. In July 1998, priceline.com issued 8,125,000 shares
of Common Stock, to the Chairman and Chief Executive Officer that resulted in
the recognition of a charge of $6.5 million with respect to these shares. The
shares were issued as compensation for agreeing to accept the position.

      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.

      Other Income, Net

      Other income, 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.

Liquidity and Capital Resources

      At December 31, 1999, the Company had approximately $171.9 million in cash
and cash equivalants, and short-term investments.

      Net cash used in operating activities was $63.0 million, $40.9 million and
$774,000 for the years ended December 31, 1999 and 1998 and for the period July
18 (inception) through December 31, 1997, respectively. Net cash used in
operating activities was primarily attributable to net losses.

      Net cash used in investing activities was $68.2 million, $6.6 million and
$1.3 million for the years ended December 31, 1999 and 1998 and for the period
July 18 (inception) through December 31, 1997, respectively. Net cash used in
investing activities was primarily related to purchases of property and
equipment, and in 1999 for investments in marketable securities.


                                       31

      Priceline.com has certain commitments for capital expenditures as part of
its ongoing business cycle. None of these commitments are material to the
financial statements either individually or in the aggregate. Capital
expenditures, primarily for computer equipment and software, were $27.4 million
for the year ended December 31, 1999. As a result of its rapid growth,
priceline.com expects to increase capital expenditures for purchased computer
hardware, internally developed software, other equipment and leasehold
improvements.

      Net cash provided by financing activities was $210.8 million, $101.1
million and $2.1 million for the years ended December 31, 1999 and 1998 and for
the period July 18 (inception) through December 31, 1997, respectively. Net cash
provided by financing activities resulted primarily from the issuance of equity
securities referred to below.

      In April 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. Offering proceeds to priceline.com, net of approximately $11.2 million in
aggregate underwriters' discounts and commissions and $4.5 million in related
expenses, were approximately $144.3 million. In August 1999, priceline.com
completed a public offering in which it sold 1,000,000 shares of its Common
Stock at a price of $67.00 per share. Offering proceeds to priceline.com, net of
approximately $2.5 million in aggregate underwriters' discounts and commissions
and $2.0 million in related expenses, were approximately $62.5 million.

      During 1997, 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. In December 1998, priceline.com sold equity
securities in a private offering to a group of corporate and institutional
investors and high net worth individuals for approximately $54.4 million.
Included in that group were 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.

      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.

      In July 1999, priceline.com made a $6.0 million loan to an executive of
the Company, pursuant to the terms of his employment agreement dated June 14,
1999. The loan bears interest annually at 5.82% per annum. In the first quarter
of 2000, priceline.com made loans to two executives aggregating $5.0 million,
which bear interest at 6.56%. Subject to certain prepayment obligations and to
forgiveness in the event of certain changes of control, death, or termination
without cause, pursuant to the terms of these loans, accrued interest and
principal are payable after five years, but are forgiven under certain
circumstances if the executive remains employed by the Company at that time.
Upon any forgiveness of the loans, the Company would recognize as compensation
expense an amount up to the amount of principal and interest forgiven.

      Priceline.com believes that its existing cash balances and liquid
resources will be sufficient to fund its operating activities, capital
expenditures and other obligations through at least the next twelve months.
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 were raised


                                       32
<PAGE>

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 other than through investments in licensees discussed
above, 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 July 1999, the FASB issued Statement No. 137, "Accounting for
Derivative Instruments and Hedging Activities-Deferral of Effective Date of FASB
No. 133". The Statement defers for one year the effective date of FASB Statement
No. 133, "Accounting for Derivative Instruments and Hedging Activities". The
rule now will apply to fiscal quarters of fiscal years beginning after June 15,
2000. In June 1998, SFAS No. 133 "Accounting for Derivative Instruments and
Hedging Activities" was issued. The statement will require the recognition of
all derivatives as either assets or liabilities in the balance sheet and the
measurement of those instruments at fair value. Derivatives that are not hedges
must be adjusted to fair value through income. If the derivative is a hedge,
depending on the nature of the hedge, changes in the fair value of derivatives
will either be offset against the change in fair value of the hedged assets,
liabilities, or firm commitments through earnings or recognized in other
comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of the derivative's change in fair value will be immediately
recognized in earnings. The Company has not yet determined the effect of SFAS
No. 133 will have on the earnings and financial position of the Company.

      In 1999, the Company adopted Statement of Position (SOP) 98-1, "Accounting
for the Costs of Computer Software Developed or Obtained for Internal Use." This
standard requires certain direct development costs associated with internal-use
software to be capitalized including external direct costs of material and
services and payroll costs for employees devoting time to the software projects.
These costs are included in software and are amortized over a period not to
exceed three years beginning when the asset is substantially ready for use.
Costs incurred during the preliminary project stage, as well as maintenance and
training costs, are expensed as incurred.

Tax Matters

Federal Air Transportation Tax on Airline Ticket Sales

      A Federal transportation tax is imposed upon the sale of airline tickets.
The tax is based on a percentage of the cost of transportation, which was 9% for
periods prior to October 1, 1998, 8% for the period October 1, 1998 through
September 30, 1999 and 7.5% thereafter. The Company has historically interpreted
the tax regulations as requiring that the tax be computed based on the amount
charged by the airline to priceline.com for the airline ticket and the Company's
participating airlines have collected and remitted the tax based on this
amounts. The Company applied for a ruling from the Internal Revenue Service (the
"Service") confirming this interpretation. In December 1999, the Service
indicated to the Company that it was unlikely that a favorable ruling would be
issued. The Company subsequently withdrew its ruling request because of the
uncertainty of the outcome. Because the Company anticipated the possibility of
an adverse ruling on this issue, the Company accrued


                                       33
<PAGE>

approximately $1.9 million relating to the balance of the tax liability for
tickets sold prior to that date. The Company believes this accrual to be
adequate but there can be no assurance as to the final outcome because a formal
ruling has not been issued by the service.

Non-Qualified Stock Options

      As of December 31, 1999, we had outstanding non-qualified stock options to
purchase 27,024,740 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 $13.93 per share, subject to adjustment in accordance
with the 1997 Omnibus Plan and the 1999 Omnibus Plan.

Year 2000 Readiness Disclosure

      The following disclosure may be deemed "Year 2000 Readiness Disclosure"
pursuant to the Year 2000 Information and Readiness Disclosure Act.

      Since inception, the Company has dedicated substantial resources to
address the potential issues related to Year 2000 programming and related
concerns. As a result of these efforts, the Company has not experienced to date
any material disruption in its operations in connection with, or following, the
transition of Year 2000.

      Since the Company was cognizant of Year 2000 issues during the development
of its systems and products since inception, specific costs related to Year 2000
issues can not be quantified. There were no material additional costs incurred
to make any previously existing product or services Year 2000 compliant.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

      Priceline.com currently has no floating rate indebtedness, holds no
derivative instruments other than through investments in licensees described in
this Annual Report on Form 10-K and does not earn significant foreign-sourced
income. Accordingly, changes in interest rates or currency exchange rates do not
generally have a direct effect on priceline.com's financial position. However,
changes in currency exchange rates may affect the cost of international airline
tickets and international hotel reservations offered through the priceline.com
service, and so indirectly affect consumer demand for such products and
priceline.com's revenue. In addition, to the extent that changes in interest
rates and currency exchange rates affect general economic conditions,
priceline.com would also be affected by such changes.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
priceline.com Incorporated

      We have audited the accompanying balance sheets of priceline.com
Incorporated (the "Company") as of December 31, 1999 and 1998, and the related
statements of operations, changes in stockholders' equity, and cash flows for
the years ended December 31, 1999 and 1998 and the period July 18, 1997
(inception) to December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these 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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the 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 financial statements present fairly, in all material
respects, the financial position of the Company as of December 31, 1999 and
1998, and the results of its operations and its cash flows for the years ended
December 31, 1999 and 1998 and the period July 18, 1997 (inception) to December
31, 1997 in conformity with generally accepted accounting principles.

1. BUSINESS DESCRIPTION

      Priceline.com Incorporated ("priceline.com", or the "Company") 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 Own
Price(SM)-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. The Company then accesses a database of
inventory available to the Company for purchase to determine whether
priceline.com can fulfill the customer's offer. Consumers agree to hold their
offers open for a specified period of time and, once fulfilled, offers generally
cannot be canceled. The Company benefits consumers by enabling them to save
money, while at the same time benefiting 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.

      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. 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. During the years ended December 31, 1999 and 1998, Walker Digital
provided the Company with a variety of services including subleasing office
facilities to the Company. Charges to the Company for such services aggregated
approximately $1,411,000 and $706,000, respectively. In addition, the Company
charged Walker Digital $1,800,000 and $384,831 for the years ended December 31,
1999 and 1998, respectively, for certain services, including legal and
accounting services and IT infrastructure. Such amounts have been offset against
general and administrative expenses in the accompanying statements of
operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Presentation--The financial statements for all periods presented
include the financial statements of priceline.com and Priceline Travel. 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.
All significant inter-company 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, 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 Company's investment in
Lending Tree, Inc. was valued at cost as there was no market for its securities
at December 31, 1999. The Company recognized income for the warrant to purchase
common stock of Priceline WebHouse Club, Inc. at estimated fair market value, as
determined by an independent valuation firm. The carrying value of the capital
lease obligations and long-term debt approximates fair value because the
interest

                    NOTES TO FINANCIAL STATEMENTS (Continued)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

rates on these obligations are comparable to the interest rates that could have
been obtained at the dates of the respective balance sheets.

      Cash and Cash Equivalents, and Short-term Investments--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. Marketable
securities are considered "trading securities" and valued at fair value.

      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.

      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.

      Software Capitalization--In 1999, the Company adopted Statement of
Position (SOP) 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use." This standard requires certain direct development
costs associated with internal-use software to be capitalized including external
direct costs of material and services and payroll costs for employees devoting
time to the software projects. These costs are included in software and are
amortized over a period not to exceed three years beginning when the asset is
substantially ready for use. Costs incurred during the preliminary project
stage, as well as maintenance and training costs, are expensed as incurred.

      Revenues and Cost of Revenues--The Company recognizes and records revenues
in a variety of ways depending on the product or service sold. With respect to
airline ticket, hotel room and rental car services, the Company recognizes as
revenue the amount received from the customer, net of taxes, and records as the
cost of revenue the amount that the Company pays the respective airline or
hotel. With respect to its automobile service, the Company earns a fixed fee
from both the customer and the seller after the transaction is consummated. With
respect to its home financing service, during 1999 the Company received a
percentage of the fees earned by third parties in connection with the closing of
mortgage loans. Going forward, the mortgage product will be offered through
National Mortgage Center LLC (doing business as pricelinemortgage (
"pricelinemortgage"), a Company that has been licensed to use the priceline.com
demand collection system. The Company also generates revenues through adaptive
marketing programs with third parties that pay the Company fees for marketing
their customer acquisition programs. Additionally, the Company generates
revenues from third party sources, including a customer processing fee for
airline, hotel and rental car services, and ancillary reservation booking fees
from the Worldspan reservation system for booking of airline flight segments and
hotel reservations through the Worldspan system. Consumer processing fees are
payable to the Company and recognized as revenue only upon completion of
successful transactions.

      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, hotel room and rental car services, revenues are
generated by transactions with customers who make offers to purchase airline
tickets and reserve hotel rooms and rental cars supplied to priceline.com by
participating sellers. Revenues and related costs are recognized if, and when,
the Company accepts and fulfills the


                                       48

                    NOTES TO FINANCIAL STATEMENTS (Continued)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

customer's offer. 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, hotel and rental car 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, the Company receives no fees from consumers. The Company recognizes
revenue from fees paid directly by its strategic partner through the operation
of its home financing services. Because the Company acts as an intermediary
between the customer and the seller in auto and home financing transactions,
revenues for these products and services are 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.

      Priceline.com expressly permits only credit cards as an acceptable form of
payment from its consumers. On rare occasions, the Company provides refunds and
makes certain customer accommodations to individual customers to satisfy
disputes and complaints. The Company accrues for such expected losses 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.

      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
accommodations and 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.

      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 of the option.

      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


                                       49
<PAGE>

                    NOTES TO FINANCIAL STATEMENTS (Continued)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

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 basic and diluted earnings per
share in accordance with Statement of Financial Accounting Standards No. 128
("SFAS 128"), "Earnings per Share". SFAS 128 requires the Company to report both
basic earnings per share, which is based on the weighted average number of
common shares outstanding, and diluted earnings per share, which is based on the
weighted average number of common shares outstanding and all dilutive potential
common shares outstanding. Since the Company incurred losses for all periods
presented, the inclusion of options in the calculation of weighted average
common shares is anti-dilutive; and therefore there is no difference between
basic and diluted earnings per share.

      Business Risk--Business risks include the following:

      Competition--The markets for the products and services offered on the
priceline.com service are intensely competitive. The Company competes with both
traditional distribution channels and online services. The Company currently or
potentially competes with a variety of companies with respect to each product or
services offered. The Company potentially faces competition from a number of
large online services that have expertise in developing online commerce and in
facilitating Internet traffic. Many competitors have significant competitive
advantages. For example, airlines, hotels and other suppliers also sell their
products and services directly to consumers and have established Web sites.
Internet directories, search engines and large traditional retailers have
significantly greater operating histories, customer bases, technical expertise,
brand recognition and/or online commerce experience than the Company. In
addition, certain competitors may be able to devote significantly greater
resources to furthering their business.

      Dependence on Airline Industry and Certain Carriers--The Company's near
term, and possibly long term, prospects are significantly dependent upon the
sale of leisure airline tickets. Sales of leisure airline tickets represented
approximately 85% and 86% of total revenues for the years ended December 31,
1999 and 1998, respectively. As a result, currently the Company is substantially
dependent upon the continued participation of the airlines in the priceline.com
service in order to maintain and continue to grow its total revenues.
Significantly reducing the Company's dependence on the airlines is likely to
take a long period of time and there can be no guarantee that the Company will
succeed in reducing that dependence.

      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 marketable
securities are deposited with high credit quality financial institutions.
Accounts receivable are derived from the revenues earned from customers in the
U.S. and are denominated in U.S. dollars. The Company maintains an allowance for
uncollectible accounts based upon the expected collectibility of accounts
receivable.

                    NOTES TO FINANCIAL STATEMENTS (Continued)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

      Barter Transaction--In 1999, the Company entered into one barter
transaction to exchange services for advertising. The transaction was recorded
at the estimated fair value of the services expected to be received. Revenue of
$375,000 from this transaction was recognized in 1999, when the service was
provided and will be expensed during 2000, when the advertising is provided to
priceline.com.

      Segment Reporting--The Company operates as a single segment and will
evaluate additional segment disclosure requirements as it expands its
operations. All of the operations and identifiable assets are in the United
States.

      Reclassification--Certain amounts in prior years' financial statements
have been reclassified to conform to the current year presentation.

      Recent Accounting Pronouncements

      In July 1999, the FASB issued Statement No. 137, "Accounting for
Derivative Instruments and Hedging Activities-Deferral of Effective Date of FASB
No. 133". The Statement defers for one year the effective date of FASB Statement
No. 133, "Accounting for Derivative Instruments and Hedging Activities". The
rule now will apply to fiscal quarters of fiscal years beginning after June 15,
2000. In June 1998, SFAS No. 133 "Accounting for Derivative Instruments and
Hedging Activities" was issued. The statement will require the recognition of
all derivatives as either assets or liabilities in the balance sheet and the
measurement of those instruments at fair value. Derivatives that are not hedges
must be adjusted to fair value through income. If the derivative is a hedge,
depending on the nature of the hedge, changes in the fair value of derivatives
will either be offset against the change in fair value of the hedged assets,
liabilities, or firm commitments through earnings or recognized in other
comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of the derivative's change in fair value will be immediately
recognized in earnings. The Company has not yet determined the effect of SFAS
No. 133 will have on the earnings and financial position of the Company.

3. SHORT-TERM INVESTMENTS

      At December 31, 1999, the Company held short term instruments which were
classified as trading securities; accordingly, they are carried at fair value on
the balance sheet. Net unrealized gains (losses) of $13,000 have been recognized
in the financial statements. Marketable securities at December 31, 1999 include
the following (in thousands):


                                                              December 31, 1999

      Included in other assets is a $2.0 million equity investment in Lending
Tree, Inc., an internet-based home financing service provider. Since the Company
owns less than 20% of Lending Tree and does not exert significant influence over
the investee, the Company accounts for the investment on the cost basis. In
accordance with SFAS No. 115, the Company deems these securities as available
for sale. Because there was no readily determinable value for shares of Lending
Tree at December 31, 1999, the Company has valued its investment at cost. The
Company's home financing service is offered through a joint marketing
arrangement with Lending Tree.

      Depreciation and amortization expense was approximately $5,337,000,
$1,860,000 and $212,000 for the years ended December 31, 1999 and 1998, and for
the period July 18, 1997 to December 31, 1997, respectively.

6. LONG TERM DEBT

      In April 1998, priceline.com issued a promissory note to an investor for
$1,000,000. The promissory note bore interest at a rate of 6% per annum. In
connection with the promissory note, priceline.com issued detachable warrants to
purchase 62,500 shares of common stock at $0.80 per share. The note was repaid
in 1999.

7. STOCKHOLDERS' EQUITY

      In March 1999, the Company effected a 1.25:1 stock split. All share and
per share amounts have been retroactively adjusted to reflect the stock split.

      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 of all the rights, title, and interest in certain patents and
patent applications relating to buyer driven commerce.

7. STOCKHOLDERS' EQUITY (Continued)

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

      In April 1999, the Company completed an initial public offering in which
it sold 10,000,000 shares of its Common Stock, $0.008 par value. Offering
proceeds to the Company, net of underwriter discounts and commissions and other
related expenses, were approximately $144.3 million. At the time of the
offering, shares of the Series A and Series B Preferred Stock were automatically
converted, subject to anti-dilution adjustment, into an equal number of shares
of Common Stock.

      In August 1999, the Company completed a public offering in which it sold
1,000,000 shares of its Common Stock and certain stockholders of the Company
sold 3,500,000 shares of common stock at a price of $67.00 per share. Offering
proceeds to priceline.com, net of underwriters discounts and commissions and
related expenses, were approximately $62.5 million.

8. WARRANTS TO PURCHASE COMMON STOCK

      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 (the "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 was to 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 $3.0 million is included in cost of revenues-supplier warrant
costs and $55.7 million is included in expenses-warrant costs, net in the
accompanying statements of operations.

      In November 1999, the Company further amended the Delta warrant to provide
Delta with a cashless exercise right. Upon the exercise of the warrant, Delta
acquired a total of 16,525,834 shares of Common Stock of priceline.com. In
conjunction with that transaction, Delta sold 2,085,767 shares of priceline.com
Common Stock to priceline.com's founder and Vice Chairman Jay S. Walker for an
aggregate purchase price of $125 million. The Company further gave Delta the
right to exchange six million shares of priceline.com common stock for six
million shares of newly issued convertible preferred stock that may be converted
into priceline.com stock on a one-for-one basis. To date, Delta has not elected
to exercise the conversion right.

8. WARRANTS TO PURCHASE COMMON STOCK (Continued)

      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. That amount is
included in expenses- warrant costs, net in the accompanying statements 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 a substantial penalty
will be imposed. 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 are expected to be provided to the Company.

      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 incurred a non-cash charge of approximately $88.4
million during the third quarter of 1999 representing the fair value of the
warrant on the grant date. In November 1999, the Company amended the Continental
warrant to allow the exercise price to fall within the range of the warrants
issued to other airlines discussed below. Priceline.com incurred a non-cash
charge of approximately $3.5 million during the fourth quarter as a result of
the warrant amendment.

      In November 1999, the Company entered into separate Participation Warrant
Agreements with each of eight major domestic airlines relating to their
inclusion in the Company's leisure airline ticket service. Under the
Participation Warrant Agreements, the airlines were granted warrants to purchase
a total of 20 million shares of priceline.com Common Stock at exercise prices
ranging from $52.625 to $59.933 per share. All warrants were fully vested on the
date of grant, but generally are not exercisable until November 2005, subject to
acceleration under certain circumstances. Priceline.com incurred additional
warrant costs of approximately $1.1 billion during the fourth quarter of 1999 as
a result of the issuance of these warrants.

9. STOCK OPTION PLANS

      In February 1999, the Company adopted 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. In addition, the Company had previously adopted the 1997
Omnibus Plan (the "1997 Plan"). The 1999 Plan and 1997 Plan provide for grants
of options to purchase up to 9,375,000 and 23,875,000 shares of Common Stock,
respectively, at a purchase price equal to the fair market value on the date of
grant. Generally, options from both plans vest over three years from the date of
grant. Compensation expense for options granted to non-employees, included in

      The fair value of options granted during 1999 was determined on the date
of grant using the Black-Scholes method. The weighted average fair value of
options granted during 1999 was estimated to be approximately $52.45, based on
the following assumptions: volatility of 107%, risk free interest rate of 5.9%,
an expected life of 3 years, and no dividends.

      The fair value of options granted during 1998 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, based on
the following assumptions: volatility of 0%, risk free interest rate of 6.0%, an
expected life of 3 years, and no dividends.

10. 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 approximately $1.1 billion, and accordingly, no
provision for income taxes is reflected in the accompanying statements of
operations.

      The tax effects of temporary differences that give rise to significant
portions of deferred tax assets at December 31, 1999 and 1998 are as follows (in
thousands):

                                                        1999             1998

      A valuation allowance for the full amount of the net deferred tax asset

not that the benefit of such items will not be realized. The

      Federal Air Transportation Tax--A Federal transportation tax is imposed
upon the sale of airline tickets. The tax is based on a percentage of the cost
of transportation, which was 9% for periods prior to October 1, 1998, 8% for the
period October 1, 1998 through September 30, 1999 and 7.5% thereafter. The
Company has historically interpreted the tax regulations as requiring that the
tax be computed based on the amount charged by the airline to priceline.com for
the airline ticket and the Company's participating airlines have collected and
remitted the tax based on this amount. The Company applied for a ruling from the
Internal Revenue Service (the "Service") confirming this interpretation. In
December 1999, the Service indicated to the Company that it was unlikely that a
favorable ruling would be issued. The Company subsequently withdrew its ruling
request because of the uncertainty of the outcome. Because the Company
anticipated the possibility of an adverse ruling on this issue, the Company
accrued approximately $1.9 million relating to the balance of the tax liability
for tickets sold prior to that date. The Company believes this accrual to be
adequate, but there can be no assurance as to the final outcome because a formal
ruling has not been issued by the service.

11. LICENSING, MARKETING and TECHNOLOGY AGREEMENTS

      In 1999, priceline.com licensed its name and demand collection system to
Priceline WebHouse Club, Inc. ("WebHouse") and agreed to provide certain
services to WebHouse. WebHouse is an independent company. Under the negotiated
agreements, priceline.com receives a royalty based on a percentage of WebHouse
revenues and payments for services at estimated fair value. The Company realized
$33,777 of royalty revenue in 1999. As an inducement to enter into a
relationship with WebHouse, priceline.com received a warrant to purchase a
majority of the shares of WebHouse common stock. The warrants are
non-forfeitable, fully vested upon grant, exercisable in five years or earlier
upon the occurrence of certain events, and do not require the performance of any
additional services. Upon receipt of the warrant in the fourth quarter,
priceline.com recognized $188.8 million of income representing the amount of the
estimated fair value of the warrants, based on an independent valuation.
Priceline.com is negotiating a similar arrangement with another independent
Licensee, Priceline Perfect Yardsale, Inc. ("Yardsale").

      Additionally, priceline.com and WebHouse entered into an Intellectual
Property License Agreement, Marketing and Technical Services Agreement and a
Services Agreement pursuant to which priceline.com provides certain marketing,
technology and other services to WebHouse and receives compensation at fair
value for services rendered. Accordingly, WebHouse paid the Company $1.65
million during 1999 under these agreements.

      Priceline.com and Yardsale also entered into a preliminary agreement
pursuant to which priceline.com licenses its name and demand collection system
and provides certain marketing, technology and other services to Yardsale and
receives compensation at fair value for services rendered. The agreements with
Yardsale were not in effect until after January 1, 2000.

12. COMMITMENTS AND CONTINGENCIES

      Legal Proceedings On January 6, 1999, priceline.com received notice that a
third party patent applicant and patent attorney, Thomas G. Woolston,
purportedly had filed in December 1998 with the United States Patent and
Trademark Office a request to declare an interference between a patent
application filed by Woolston and priceline.com's U.S. Patent 5,794,207.
Priceline.com currently is awaiting information from the Patent Office regarding
whether it will initiate an interference proceeding.

      On January 19, 1999, Marketel International Inc. (Marketel), a California
corporation, filed a lawsuit against priceline.com, 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, among other things, that the
defendants conspired to misappropriate Marketel's business model, which
allegedly was provided in confidence approximately ten years ago. The amended
complaint also alleges that four former Marketel employees are the actual sole
inventors or co-inventors of U.S. Patent 5,794,207, which was issued on August
11, 1998 and has been assigned to priceline.com. Marketel asks that the patent's
inventorship be corrected accordingly.

      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 strongly
dispute the material legal and factual allegations contained in Marketel's
amended complaint and believes that the amended complaint is without merit.
Priceline.com intends to defend vigorously against the action. 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.

      On October 13, 1999, priceline.com filed a complaint in the United States
District Court for the District of Connecticut under the caption Priceline.com
Incorporated v. Microsoft Corporation and Expedia, Inc., No. 399CV1991 (AWT)
alleging that Microsoft Corporation and Expedia, Inc., a subsidiary of Microsoft
Corporation, infringe priceline.com's U.S. Patent 5,794,207 by operating the
defendants' "Hotel Price Matcher" service, and that the defendants' conduct
toward priceline.com violated the Connecticut Unfair Trade Practices Act. On
December 20, 1999 defendants moved the Court to dismiss the complaint for
failure to name a necessary party, Marketel. On March 21, 2000, the presiding
judge stated that he intends to deny defendant's motion to dismiss, and that a
decision will be forthcoming. On December 23, 1999 the Court granted
priceline.com's motion to supplement the complaint to expressly include
defendant's "Flight Price Matcher" service. In the lawsuit, priceline.com is
seeking declaratory relief, permanent injunctive relief and actual and punitive
damages.

      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

1.3   No Amendment of Warrant Agreements

      Priceline shall not amend, during the period from the date hereof until

      to do so, Priceline shall not consent to or participate in, a sale of
      equity securities of Priceline until after the Release Date.

1.5   Convertible Preferred Stock

      At Delta's option, , all of the shares of Priceline Common Stock held by
      Delta (other than the Market Sale Shares) will be exchanged for
      $359,580,000 aggregate principal amount of a newly issued class of
      convertible preferred stock of Priceline bearing an accruing semi-annual
      paid-in-kind dividend at a rate of eight percent (8%) per annum, payable
      semiannually, in Priceline common shares (the "Convertible Preferred
      Stock"), which such exchange to be structured to the extent possible in a
      tax-free transaction to Delta pursuant to I.R.C. Section 368 (a)(1)(E).
      Any shares of Convertible Preferred Stock held by Delta after the date of
      issuance may be converted at Delta's option at any time into shares of
      Priceline common stock at a one (1) to one (1) ratio (i.e. a zero percent
      premium). The Convertible Preferred Stock will have a final maturity of
      ten (10) years from the date of issue and be subject to a mandatory
      redemption at the tenth (10th) anniversary for cash at a price per share
      of $59.93; provided that Priceline shall have a call right for the
      Convertible Preferred Stock after three (3) years from the date of issue

<PAGE>

      convert its Convertible Preferred Stock during such 30 day period. Whether
      or not Priceline has exercised its call right, Delta is guaranteed the
      first six semiannual dividends. The Convertible Preferred Stock will be

      any existing or future preferred stock issued by Priceline, and will have
      priority over the the common stock of Priceline. Delta will have voting
      rights for the Convertible Preferred Stock as if Delta held an equivalent
      number of Priceline common shares (i.e., on a one to one ratio). In the
      event that Priceline issues a cash dividend to the holders of common
      shares, then Delta shall be entitled to demand a cash dividend on the
      Convertible Preferred Stock in lieu of the paid-in-kind dividend.

      In the event of a change of control of Priceline where cash is a portion
      of the consideration paid by the acquiring company, Delta will have the
      right to elect to receive the greater of par (cash at a price per share of
      $59.93) or the cash value of the transaction. If the transaction is for
      stock, the exchange ratio will be adjusted such that Delta receives the
      same monetary consideration for its Convertible Preferred Stock.

      Priceline hereby confirms that such shares, when converted to Priceline
      common stock, shall have demand and piggyback registration rights under
      the existing Amended and Restated Registration Rights Agreement dated
      December 8, 1998 by and among Delta, Priceline, and other parties or any
      successor or substitute registration rights agreement thereto.

      The Convertible Preferred Stock will be subordinated to any indebtedness
      of Priceline, will rank pari passau with any existing or future preferred
      stock issued by Priceline, and will have priority over the the common
      stock of Priceline. Delta will have voting rights for the Convertible
      Preferred Stock as if Delta held an equivalent number of Priceline common
      shares (i.e., on a one to one ratio). In the event that Priceline issues a
      cash dividend to the holders of common shares, then Delta shall be
      entitled to demand a cash dividend on the Convertible Preferred Stock in
      lieu of the paid-in-kind dividend.

AMENDMENT TO THE AIRLINE PARTICIPATION AGREEMENT AND THE GENERAL AGREEMENT

This Amendment ("Amendment"), dated the 17th day of November, 1999, amends the
Airline Participation Agreement ("APA") and the General Agreement ("GA"), dated
August 31, 1998, as amended, between and among Delta Air Lines, Inc. ("Delta")
and priceline.com Incorporated and PriceLine Travel, Inc. which merged with and
into priceline.com Incorporated on March 24, 1999 ("Priceline"). Unless
otherwise defined herein, capitalized terms shall have the meanings set forth in
the APA and the GA, as applicable.

1.    The following provision replaces Section 3.1 of the GA in its entirety:

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

      (a)   Delta consents to the participation in Priceline by the U.S.
            carriers identified in the attached Schedule 3.1; subject to the
            following restrictions:

            (i)   Priceline shall not issue tickets on Northwest Airlines to or
                  from ATL, except for the following O&D markets: DTW-ATL,
                  MSP-ATL, and MEM-ATL;

            (ii)  Priceline shall not issue tickets on Continental Airlines to
                  or from ATL, except for the following O&D markets: EWR-ATL,
                  CLE-ATL, HOU-ATL and IAH-ATL;

            (iii) Priceline shall not issue tickets on United Airlines to or
                  from ATL, except for the following O&D markets: ORD- ATL,
                  DEN-ATL, SFO-ATL, and IAD-ATL;

            (iv)  Priceline shall not issue tickets on USAirways to or from ATL,
                  BOS or LGA except for the following O&D markets: PIT-
                  ATL/BOS/LGA, PHL-ATL/BOS/LGA, and CLT-ATL/BOS/LGA.
                  Notwithstanding the above restriction, Priceline may issue
                  tickets on USAirways to or from BOS or LGA in O&D markets not
                  served by nonstop flights operated by Delta or a carrier
                  operating a flight under Delta's two letter "DL" designator
                  code, provided, that Priceline shall restrict its ticket BOS
                  or LGA sales on USAirways within thirty (30) days of any new
                  nonstop BOS or LGA service offered by Delta or a carrier
                  operating a flight under Delta's two letter "DL" designator
                  code; and

            (v)   Priceline shall not issue tickets on American Airlines to or

<PAGE>

                  from ATL, except for the following O&D markets: ORD-ATL,
                  DFW-ATL and MIA-ATL. In the event that American Airlines (or
                  an affiliate of American Airlines), merges with or acquires
                  substantial assets of USAirways in Boston, then, in addition
                  to the ATL market restriction, Priceline shall not issue
                  tickets on American Airlines to or from BOS, except for the
                  following O&D markets: ORD- BOS, DFW- BOS and MIA- BOS;
                  provided, that Priceline may issue tickets on American
                  Airlines to or from BOS in O&D markets not served by nonstop
                  flights operated by Delta or a carrier operating a flight
                  under Delta's two letter "DL" designator code subject to;
                  provided, further, that Priceline shall restrict its BOS
                  ticket sales on American within thirty (30) days of any new
                  nonstop BOS service offered by Delta or a carrier operating a
                  flight under Delta's two letter "DL" designator code. In the
                  event that American acquires or operates a hub airport in PIT,
                  PHL or CLT as a result of the acquisition of substantially all
                  of the assets of USAirways in PIT, PHL or CLT, then Priceline
                  may issue tickets on American Airlines, respectively, in the
                  PIT-ATL, PHL-ATL, or CLT-ATL markets, respectively.

      (b)   Delta consents to the participation in Priceline by the
            International Carriers identified in the attached Schedule 3.1;
            subject to the following restrictions:

            (i)   Priceline shall not issue tickets for international travel on
                  Austrian Airlines, Sabena, Swissair, AeroMexico, Air Jamaica,
                  Korean Airlines, Air Canada, All Nippon Airways, El Al Israel
                  Airlines, Qantas, Japan Airlines, Alitalia and Aerolineas
                  Argentinas to or from ATL or BOS, except for offers
                  originating from O&D markets not served by Delta or a carrier
                  operating a flight under Delta's two letter ("DL") designator
                  code.

      (c)   Notwithstanding the restrictions set forth in Section 3.1(a) and
            3.1(b), Priceline may, in addition to other rights set forth in this
            Amendment issue tickets (i) on Turkish Airlines solely in the New
            York (JFK) - Tel Aviv O&D market, (ii) on flights operated by
            Participating Airlines in O&D markets not served by Delta or a
            carrier operating a flight under Delta's two letter designator code,
            and (iii) on code share flights operated by third party carriers
            (including commuter carriers) where the Participating Carrier's two
            letter designator code used to identify its flights (as published
            and used in the Official Airline Guide (OAG), computer reservation
            systems (CRS's) and internal reservations systems) appears in the
            carrier code box of the flight coupon; provided, that the market
            restrictions set forth in Section 3.1(a) and 3.1(b) are applicable
            to such code share flights.


                                       2
<PAGE>

      (d)   Priceline shall not issue tickets on carriers that are not listed on
            Schedule 3.1. The participation of other domestic and international
            carriers in Priceline, and the sale of tickets on such carriers, is
            subject to Delta's prior written consent. Delta agrees to meet with
            Priceline to discuss objective criteria by which new international
            participants could be added.

      (e)   For purposes of Section 3.1, an O&D market shall be considered to be
            served by Delta or a carrier operating a flight under Delta's two
            letter designator code at any time scheduled service is offered for
            sale by one or more such carriers.

2.    The following test is added as Section 7.15 (f) of the GA:

Reporting Audit Rights:

The General Agreement will be amended to state that Priceline will make
available (at no cost to Delta) to all Participating Airlines, on an agreed
production schedule, the following information for all Domestic and
International markets in which such Participating Airlines provide fares and
availability ("Applicable O&D's"):

o     Methodology for determination of "Reasonable Demand" where "Reasonable
      Demand" denotes offers acceptable to Priceline for possible fulfillment

o     Notification of changes to "Reasonable Demand" methodology

o     O&D routing, number of passengers, revenue, and average fare data for all
      Priceline tickets for each Participating Airline The above data will be
      made available to each Participating Airline no later than 30 days
      following the end of each calendar month in the case of segment data and
      each calendar quarter in the case of data relating to number of
      passengers, revenue and average fare data.

o     With respect to Delta only

      -     Weekly frequency distribution of offer price demand by applicable
            O&D to include mode, range, minimum/maximum level, mean, median,
            standard deviation and bid price trends

      -     As soon as practical but in any case within six months, make
            available to Delta with weekly detail and summary report that
            identifies rejected offers and the reasons leading to the rejections
            (e.g., "bid was too low by $20, no "L" inventory LGA-ATL Nov 1)

o     Priceline will continue to provide to Delta all the data it currently
      submits on a regular basis (i.e., Delta Air Lines' Weekly Ticket Report -
      Summaries of Ticket Sales by O&D - Domestic and International), including
      data routinely submitted in response to Delta ad hoc requests.

      Priceline will disclose bookings through Priceline in a format comparable
      to the CRS MIDT data on a weekly basis and Priceline shall make available


                                       3
<PAGE>

      such data to all Participating Carriers.

      Priceline agrees to make available to Delta the audit plan and the report
      prepared by priceline's auditors concerning Priceline's compliance with
      the Participation Agreement and Delta General Agreement. In addition,
      Delta will have the right to audit Priceline for compliance on all
      contractual market, product, and other agreements and to receive regular
      reports measuring compliance to such contractual terms.

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

      7.11 All Participating Carriers will be given the first opportunity to
      fill a customer ticket request based on a formula which allocates such
      requests in proportion to the aggregate domestic or international market
      share (as applicable) of each Participating Carrier for each O&D
      requested. If a Participating Carrier fails to respond to a ticket request
      on its designated first look, then Priceline will allocate the request
      through a second round of preferred looks, which will be allocated in
      proportion to the aggregate domestic or international market shares (as
      applicable) of all remaining Participating Carriers for each O&D requested
      (but excluding the Participating Carrier that failed to fulfill the ticket
      request on the first look).

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

      III. Priceline Ticket Allocation Methodology

            All Participating Carriers will be given the first opportunity to
            fill a customer ticket request based on a formula which allocates
            such requests in proportion to the aggregate domestic or
            international market share (as applicable) of each Participating
            Carrier for each O&D requested. If a Participating Carrier fails to
            respond to a ticket request on its designated first look, then
            Priceline will allocate the request through a second round of
            preferred looks, which will be allocated in proportion to the
            aggregate domestic or international market shares (as applicable) of
            all remaining Participating Carriers for each O&D requested (but
            excluding the Participating Carrier that failed to fulfill the
            ticket request on the first look).


                                       4

5.    Except as provided herein, all other terms and conditions of the APA and
      the GA shall remain in full force and effect. In the event any term or
      provision of the APA or the GA is contrary to or inconsistent with this
      Amendment, the terms of this Amendment shall control.

      2. Exercise Price. The Warrants have an exercise price of $56.625 per
share of Common Stock, as adjusted pursuant to the provisions of Section 10 of
this Warrant Agreement (the "Exercise Price").

      3. Term. The Warrants are fully vested on the Issue Date. Except as
otherwise provided herein, the term of the Warrants and the right to purchase
Shares as granted herein shall be exercisable on the fifth (5th) anniversary of
the Issue Date; provided, further, that if any of the Warrants first become

will have an additional six months thereafter to exercise its purchase rights in
respect of those Warrants (the end of such five year period and additional six
months, if applicable, being referred to herein as the "Termination Date").

      4. Exercise Events.

                  (i)   If, at any point during the period between [**]
                        and [**] (the "First Measuring
                        Period"), the Company receives Net Revenue (as defined
                        in Section 4(c)) of at least $[**] million (the "First
                        Measuring Period Net Revenue Benchmark") from tickets
                        sold during the First Measuring Period for travel on the
                        Warrant Holder,

                                      -1-
<PAGE>

                        its subsidiaries and/or on the Warrant Holder's code
                        share partners using Warrant Holder's code
                        (collectively, "Warrant Holder and its Code Share
                        Partners"), the Warrant Holder will thereupon and
                        thereafter have the right to exercise Warrants, subject
                        to adjustment as provided in Section 10 hereof, equal to
                        50% of the Shares. In the event that the Company does
                        not achieve the First Measuring Period Net Revenue
                        Benchmark during the First Measuring Period, the Warrant
                        Holder will still be entitled to exercise Warrants,
                        subject to adjustment as provided in Section 10 hereof,
                        equal to [**]% of the Shares upon the expiration of the
                        First Measuring Period and thereafter if, during the
                        entire term of the First Measuring Period, Warrant
                        Holder does not voluntarily participate in any
                        name-your-price airline ticket service other than the
                        Company's and its affiliates' airline ticket services.

                  (ii)  In addition to Warrant Holder's early exercise rights
                        under Section 4(b)(i), if during the period between [**]
                        and [**] (the "Second Measuring Period"), the Company
                        receives Net Revenue (as defined in Section 4(c)) of at
                        least $[**] million (the "Second Measuring Period Net
                        Revenue Benchmark") from tickets sold during the Second
                        Measuring Period for travel on the Warrant Holder and
                        its Code Share Partners, the Warrant Holder will on [**]
                        and thereafter have the right to exercise Warrants,
                        subject to adjustment as provided in Section 10 hereof,
                        equal to [**]% of the Shares.

            (c) Net Revenue. As used in this Warrant Agreement, the term "Net
Revenue" shall mean the total ticket revenue received by the Company from
tickets sold for travel on the Warrant Holder and its Code Share Partners, net
of federal excise and segment taxes, passenger facility charges and related
fees. The parties acknowledge that credit card processing fees, and any
processing fees or similar fees charged by the Company to the consumer in
connection with the sale of a ticket shall not be included in the calculation of
Net Revenue. Attached hereto as Exhibit D is an example of the calculation of
Net Revenue.

      5. Exercise of Purchase Rights.

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

            (b) Net Issue Exercise. Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Exercise Price (at the date of calculation as set forth below),
in lieu of exercising the Warrants for cash, the Warrant Holder may elect to

[**]=Confidential Treatment requested for redacted portion


                                      -2-
<PAGE>

receive shares of Common Stock equal to the value (as determined below) of the
Warrants (or portion thereof being exercised) by surrender of the Participation
Warrant Agreement at the principal office of the Company together with the duly
executed Notice of Exercise in which event the Company shall issue to the
Warrant Holder a number of shares of Common Stock computed using the following
formula: X=Y(A-B)/ A WHERE X= the number of shares of Common Stock to be issued
to the Warrant Holder; Y= the number of shares of the Common Stock purchasable
under the Warrants or, if only a portion of the Warrants is being exercised, the
portion of the Warrants being exercised; A= the fair market value of one share
of the Company's Common Stock (at the date of such calculation); and B= Exercise
Price (at the date of such calculation). For purposes of this Section 5(b), the
calculations contemplated by this Section 5(b) shall be made as of the close of
business on the trading day immediately preceding the date of the delivery of
this Warrant Agreement and the related Notice of Exercise and the fair market
value of one share of the Common Stock shall be equal to the sales price,
regular way, as reported on Nasdaq or if no such reported sale takes place, the
average of the closing bid and asked prices, regular way, as reported on Nasdaq
or if no such bid or ask prices are reported, the average of the bid and ask
prices of a New York Stock Exchange member. The Company shall deliver, or cause
to be delivered, the shares of Common Stock issuable upon a net issue exercise
pursuant this Section 5(b) within two business days of the surrender of this
Warrant Agreement and related Exercise Notice.

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

      7. No Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant Holder's
rights to purchase the Shares.

      8. No Rights as Shareholder. This Warrant Agreement does not entitle the
Warrant Holder to any voting rights or other rights as a shareholder of the
Company with respect to the underlying Shares prior to the exercise of the
Warrant Holder's rights to purchase the Shares as provided for herein.

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

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

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

            (b) Reclassification, Etc. If the Company at any time shall, by
subdivision, combination or reclassification of securities or otherwise, change
any of the securities as to which purchase


[**]=Confidential Treatment requested for redacted portion

                                      -3-
<PAGE>

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

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

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

            (e) Other Changes. If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 10 are not strictly applicable or if strictly applicable, would not
fairly protect the purchase rights of the Warrant Holder in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number of and class of shares available under the Warrants, the Exercise
Price or the application of such provisions, so as to protect the purchase
rights of the Warrant Holder. The adjustment shall be such as will give the
Warrant Holder upon exercise for the same aggregate Exercise Price the total
number, class and kind of shares or other property as the Warrant Holder would
have owned had the Warrants been exercised prior to the event and had the
Warrant Holder continued to hold such shares until after the event requiring
adjustment.

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

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

      11. Representations and Warranties of the Warrant Holder.


[**]=Confidential Treatment requested for redacted portion

                                      -4-
<PAGE>

follows:

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

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

            (c) Governmental Authorization; Third Party Consents. No approval,
consent, compliance, exemption or authorization of any governmental authority or
agency, or of any other person or entity, is necessary or required in connection
with the execution, delivery or performance by, or enforcement against, the
Warrant Holder of this Warrant Agreement or the transactions contemplated
hereby.

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

            (e) Purchase for Own Account. The Warrants issued to the Warrant
Holder pursuant to this Warrant Agreement, and the Shares to be issued upon
vesting and exercise thereof, are being or will be acquired for the Warrant
Holder's own account and with no intention of distributing or reselling such

            (f) Restricted Securities. The Warrant Holder understands that the
Warrants and the Shares issuable upon vesting and exercise of the Warrants, will
not be registered at the time of their issuance under the Securities Act for the

and business matters as to be capable of evaluating the merits and risks of its
investment and has the ability to suffer the total loss of the investment. The
Warrant Holder further represents that it has had the opportunity to ask

conditions of the Warrants, the business of the Company, and to obtain
additional information to such Warrant Holder's satisfaction.

Investor" within the meaning of Rule 501 of Regulation D under the Securities
Act, as presently in effect.


      12. Compliance with Securities Act; Transferability of Warrant or Shares
of Common Stock.

            (a) Compliance with Securities Act. The Warrant Holder, by
acceptance hereof, agrees that the Warrants, and the shares of Common Stock to
be issued upon exercise of the Warrants, are being acquired for investment and
that such Warrant Holder will not offer, sell or otherwise dispose of the
Warrants, or any shares of Common Stock to be issued upon exercise of the
Warrants except under


[**]=Confidential Treatment requested for redacted portion

circumstances which will not result in a violation of the Securities Act of
1933, as amended (the "Securities Act"), or any applicable state securities
laws. The Warrants and all shares of Common Stock issued upon exercise of the
Warrants (unless registered under) the Securities Act and any applicable state
securities laws) shall be stamped or imprinted with a legend in substantially
the following form:

                  SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES
                  LAW. THEY MAY NOT BE SOLD OR OFFERED FOR SALE, PLEDGED,

                  EFFECTIVE REGISTRATION STATEMENT RELATED THERETO UNDER SAID
                  ACT AND APPLICABLE STATE SECURITIES LAWS OR UNLESS THE COMPANY
                  HAS RECEIVED AN OPINION OF COUNSEL THAT SUCH REGISTRATION IS
                  NOT REQUIRED TO EFFECTUATE SUCH TRANSACTION."

            (b) Exchange, Transfer, Assignment. The Warrants cannot be
exchanged, transferred or assigned otherwise than in accordance with applicable
law. Upon compliance with applicable law and surrender of the Warrants to the
Company with the Assignment Form annexed hereto as Exhibit B duly executed, and
funds sufficient to pay any transfer tax, the Company shall, without charge,
execute and deliver a new Warrant Agreement in the name of the heir, devisee or
assignee named in such instrument of assignment and this Warrant Agreement shall
promptly be canceled. Subject to the terms hereof, the Warrants may be assigned
in whole or in part.

      13. Registration Rights. Upon the parties' execution of this Warrant
Agreement and the Acknowledgment and Agreement to the Amended and Restated
Registration Rights Agreement attached hereto as Exhibit C, Warrant Holder shall
be made a party to that certain Amended and Restated Registration Rights
Agreement, dated as of December 8, 1998, by and among the Company, the
stockholders of the Company named therein and such other stockholders and
warrant holders of the Company made a party thereto. In addition, within 30 days
of the execution of this Warrant Agreement, the Company agrees to enter into an
agreement with Warrant Holder, in form and substance reasonably satisfactory to
Warrant Holder, which shall grant Warrant Holder the right to transfer its
registration rights pursuant to such Amended and Restated Registration Rights
Agreement dated as of December 8, 1998 to any assignee or assignees of all or

effected by the Company thereunder for the benefit of any such assignee.

               First Amendment to Participation Warrant Agreement

      This First Amendment to Participation Warrant Agreement dated as of
November 17, 1999 ("First Amendment"), by and between priceline.com Incorporated
(the "Company") and Continental Airlines, Inc. ("Warrant Holder").

      WHEREAS, the Company and Warrant Holder are parties to that certain
Participation Warrant Agreement dated as of July 16, 1999 (the "Warrant
Agreement"); and

      WHEREAS, the parties desire to amend the Warrant Agreement upon the terms

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

      1. Definitions. Capitalized terms use herein and not otherwise defined
herein shall have the meanings ascribed to them in the Warrant Agreement.

      2. Amendment to Warrant Agreement. The Warrant Agreement is amended as
follows:

      (A)   Section 2 of the Warrant Agreement is amended to read in its
            entirety as follows:

            "2. Exercise Price. The Warrants have an exercise price of $59.93
            per share of Common Stock, as adjusted pursuant to the provisions of
            Section 10 of this Warrant Agreement (the "Exercise Price")."

      (B)   Section 4(b) of the Warrant Agreement is hereby amended to read in
            its entirety as follows:

            "(b) Early Exercise Rights.

                  (i)   The Warrant Holder will earn the right to exercise
                        Warrants for the first 500,000 Shares, subject to
                        adjustment as provided in Section 10 hereof, from and
                        after the date during any Measuring Period (as
                        identified in Section 4(c) hereof) that the Company has
                        sold during such Measuring Period at least $40.66
                        million (for the first Measuring Period ending August 1,
                        2000) or $36 million (for any Measuring Period ending
                        after August 1, 2000) of tickets issued for travel on
                        the Warrant Holder, its subsidiaries and/or on the
                        Warrant Holder's code share partners using Warrant

<PAGE>

                        Holder's code (such amount being measured by the amount
                        paid by the Company to the Warrant Holder and its code
                        share partners net of federal excise taxes on such
                        amount, PFCs and related collections) ("Warrant Holder
                        Net Fares").

                  (ii)  The Warrant Holder will earn the right to exercise
                        Warrants for the full amount of the second 500,000
                        Shares, subject to adjustment as provided in Section 10
                        hereof, from and after the date during any Measuring
                        Period (other than the Measuring Period during which
                        Warrant Holder shall have earned the right to exercise
                        Warrants for the first 500,000 Shares) that the Company
                        has sold during such Measuring Period at least $67.0
                        million of Warrant Holder Net Fares. If, upon completion
                        of the Measuring Period immediately following the
                        Measuring Period for which Warrant Holder earned the
                        right to exercise Warrants for the first 500,000 Shares,
                        the Company has sold more than $36.0 million but less
                        than $67.0 million of Warrant Holder Net Fares during
                        such immediately following Measuring Period, Warrant
                        Holder will earn (upon completion of such immediately
                        following Measuring Period) the right to exercise that
                        number of Warrants for a portion of the second 500,000
                        Shares, subject to adjustment as provided in Section 10
                        hereof, equal to the product of (i) 500,000 (subject to
                        adjustment as provided in Section 10 hereof) multiplied
                        by (ii) a fraction, the numerator of which shall be the
                        Warrant Holder Net Fares in excess of $36.0 million sold
                        by the Company during such immediately following
                        Measuring Period, and the denominator of which shall be
                        $31.0 million. Thereafter, subject to the provisions of
                        Section 4(a), the Warrant Holder will earn the right to
                        exercise Warrants for any remaining Shares only from and
                        after the date during any Measuring Period that the
                        Company has sold during such Measuring Period at least
                        $67.0 million of Warrant Holder Net Fares.

                  (iii) Warrant Holder Net Fares will be measured separately,
                        not cumulatively. For example, if the Company has sold
                        Warrant Holder Net Fares of $40.66 million during the
                        first Measuring Period, $61.0 million during the second
                        Measuring Period, and $64.0 million during the third
                        Measuring Period, then the Warrant Holder will earn the
                        right to exercise Warrants for the first


                                       2
<PAGE>

                        500,000 Shares upon the date the Company has first sold
                        $40.66 million of Warrant Holder Net Fares during the
                        first Measuring Period, the right to exercise Warrants
                        for 403,226 Shares (500,000 x 25/31) upon completion of
                        the second Measuring Period, and no additional Shares at
                        any time during or upon completion of the third
                        Measuring Period. For purposes of this example, it is
                        assumed that no adjustment pursuant to Section 10 hereof
                        has occurred. If, for the first Measuring Period ending
                        August 1, 2000, Warrant Holder Net Fares do not equal or
                        exceed $40.66 million, Warrant Holder will not with
                        respect to the first Measuring Period earn the right to
                        exercise Warrant for the first 500,000 shares, but will
                        earn the right to exercise Warrants for the first
                        500,000 Shares in a subsequent Measuring Period if, in
                        such subsequent Measuring Period, Warrant Holder Net
                        Fares for such subsequent Measuring Period equals or
                        exceeds $36 million."

      (C)   Section 4(c) of the Warrant Agreement is hereby amended to read in
            its entirety as follows:

            "(c)  Measuring Periods. Each Measuring Period shall be a 12 month
                  period, with the first Measuring Period commencing on August
                  1, 1999 (the "First Ticket Date") and ending on the first
                  anniversary of such date. Subsequent Measuring Periods will
                  expire on the second, third, fourth and fifth anniversary of
                  the First Ticket Date, respectively; provided that the last
                  Measuring Period will expire on the fifth anniversary of the
                  Issue Date."

      3. Amendment. All references in the Warrant Agreement (and in the other
agreements, documents and instruments entered into in connection therewith) to
the "Warrant Agreement" shall be deemed for all purposes to refer to the Warrant
Agreement, as amended by this First Amendment.

effect in accordance with their terms and shall be unaffected by this First
Amendment.

      5. Counterparts. This First Amendment may be executed in counterparts,
each of which when executed shall be deemed an original and both of which when
executed shall be deemed one and the same instrument.

in accordance with, the laws of the State of Delaware, without regard to the
principles of conflicts of law of any jurisdiction.

      IN WITNESS WHEREOF, this First Amendment has been duly executed and
delivered by the authorized officers of each of the undersigned as of the date
first above written.

                        exercise Warrants for [**]% of such Shares shall not
                        accrue unless and until the Warrant Holder has, on an
                        aggregated basis with respect to the applicable
                        Measuring Period, achieved at least $[**] million of Net
                        Revenue from tickets sold by the Company during such
                        Measuring Period for travel on the Warrant Holder and
                        its Code Share Partners, and (ii) the right to exercise
                        Warrants for [**]% of such Shares shall not accrue
                        unless and until the Warrant Holder has, on an
                        aggregated basis with respect to the applicable
                        Measuring Period, achieved at least $[**] million of Net
                        Revenue from tickets sold during such Measuring Period
                        for travel on the Warrant Holder and its Code Share
                        Partners.

                  (iii) Notwithstanding the Net Revenue benchmarks specified in
                        clauses (i) and (ii) of this Section 4(b) for the early
                        exercisability of Warrants, if, with respect to any
                        Measuring Period, the Warrant Holder fails to achieve
                        the minimum Net Revenue from ticket sales by the Company
                        for travel on Warrant Holder and its Code Share Partners
                        necessary to enable Warrant Holder to exercise Warrants
                        for the [**]% or [**]% portion of Shares that would
                        otherwise become exercisable if such benchmarks were
                        achieved with respect to such Measuring Period, then,
                        effective on the last day of such Measuring Period and
                        thereafter at any time until the Termination Date,
                        Warrant Holder (i) shall have the right to exercise
                        Warrants for the [**]% portion of Warrants that would
                        have otherwise become exercisable upon achieving the
                        corresponding Net Revenue benchmark for such Measuring
                        Period, if Warrant Holder and its Code Share Partners'
                        Net Revenue, expressed

                        revenues (calculated using the same methodology used to
                        calculate Net Revenue hereunder) achieved by all
                        airlines participating in the Company's "demand
                        collection system" (collectively, "participating
                        airlines") resulting from the Company's sale of airline
                        tickets for travel on such airlines solely for U.S.
                        originating O&D's for such Measuring Period, equals or
                        exceeds [**]% of Warrant Holder's Fair Share (as defined
                        in Section 4(c) below) (the "[**]% Fair Share
                        Threshold") with respect to such Measuring Period, and
                        (ii) shall have the right to exercise Warrants for the
                        [**]% portion of Warrants that would have otherwise
                        become exercisable upon achieving the corresponding Net
                        Revenue benchmark for such Measuring Period, if Warrant
                        Holder and its Code Share Partners' Net Revenue,
                        expressed as a percentage of the aggregate of all ticket
                        sale net revenues (calculated using the same methodology
                        used to calculate Net Revenue hereunder) achieved by all
                        participating airlines resulting from the Company's sale
                        of airline tickets for travel on such airlines solely
                        for U.S. originating O&D's for such Measuring Period,
                        equals or exceeds [**]% of Warrant Holder's Fair Share
                        (the "[**]% Fair Share Threshold") with respect to such
                        Measuring Period.

                  (iv)  Notwithstanding the foregoing, if the Warrant Holder
                        does not achieve the $[**] million Net Revenue benchmark
                        specified in clause (i) of this Section 4(b) and Warrant
                        Holder does not achieve the [**]% Fair Share Threshold
                        specified in clause (iii) of this Section 4(b) for the
                        early exercisability of Warrants for the first Measuring
                        Period, Warrant Holder shall have the right upon
                        completion of the first Measuring Period and thereafter
                        until the Termination Date to exercise Warrants for the
                        [**]% portion of Shares that would otherwise become
                        exercisable upon the Company's achieving the $[**]
                        million Net Revenue benchmark or Warrant Holder's
                        achieving the [**]% Fair Share Threshold for such
                        Measuring Period, if, during the entire term of the
                        first Measuring Period, Warrant Holder does not
                        voluntarily participate in any "demand collection
                        system" (as defined in Section 4(b)) for Warrant
                        Holder's sale of airline tickets over the Internet other
                        than the Company's and its affiliates' leisure airline
                        ticket services.

            (c) Measuring Periods and Net Revenue.

                  (i)   As used in this Warrant Agreement, the term "Measuring
                        Period" shall mean a 12-month period, with the first
                        such Measuring Period commencing on December 1, 1999
                        (the "First Ticket Date"). Subsequent Measuring Periods
                        will expire on the second, third, fourth and fifth
                        anniversary of the First Ticket Date, respectively,
                        except that the fifth Measuring Period shall end on the
                        fifth (5th) anniversary of the Issue Date.

                  (ii)  As used in this Warrant Agreement, the term "Net
                        Revenue" shall mean the total amount paid or payable by
                        the Company to Warrant Holder for airline tickets sold
                        by the Company for travel on the War-

                        excise and segment taxes, passenger facility charges and
                        related fees (this is sometimes referred to herein as
                        the "Warrant Holder and its Code Share Partners' Net
                        Revenue"). The parties acknowledge that credit card
                        processing fees, and any processing fees or similar fees
                        charged by the Company to the consumer in connection
                        with the sale of a ticket shall not be included in the
                        calculation of Net Revenue.

                  (iii) As used in this Warrant Agreement, the term "Fair Share"
                        shall mean a fraction, expressed as a percentage, the
                        numerator of which shall be the domestic revenue
                        passenger miles of Warrant Holder as set forth in U.S.
                        DOT Form 41 T-1 Early data (or its successor) with
                        respect to the applicable Measuring Period, and the
                        denominator of which shall be the aggregate revenue
                        passenger miles of all participating airlines (i.e.
                        airlines which have executed airline participation or
                        similar supply agreements with the Company) as set forth
                        in U.S. DOT Form 41 T-1 Early data (or its successor)
                        with respect to the applicable Measuring Period. The
                        Chief Executive Officer or Chief Financial Officer of
                        the Company shall certify in writing to Warrant Holder,
                        on a quarterly basis (as promptly as practicable after
                        the end of each quarter contained in a Measuring
                        Period), or as otherwise reasonably requested by Warrant
                        Holder (or, if the Warrant Holder has achieved any early
                        exercise right described in Section 4(b), promptly after
                        Warrant Holder has achieved such early exercise right),
                        the calculation of Net Revenue, Fair Share and any other
                        measurement necessary to determine whether Warrant
                        Holder has achieved the early exercise rights described
                        in Section 4(b). Additionally, following the sixth (6th)
                        month of any Measuring Period, the Company will provide
                        Warrant Holder with monthly reports of its Measuring
                        Period year- to-date Net Revenue and Fair Share
                        measurements.

            (d) Warrant Holder's right to early exercise under Section 4(b) is
contingent upon Warrant Holder's participating exclusively in the Company's
leisure airline ticket service as the only "demand collection system" for
Warrant Holder's sale of airline tickets over the Internet. For purposes of this
Section 4(d), "demand collection system" is narrowly defined as an airline
ticket service that (i) enables a consumer to name the price the consumer is
willing to pay for one or more airline tickets (ii) enables the seller to bind
the consumer to the consumer's offer price upon the seller's acceptance of the
consumer's offer, and (iii) does not permit the consumer to specify the exact
airline on which the consumer is willing to fly. In order for Warrant Holder to
be entitled to the early exercise rights specified in Section 4(b), Warrant
Holder must not at any time between the date hereof and the date Warrant Holder
exercises the Warrants pursuant to an early exercise of Warrants in accordance
with Section 4(b), participate in any "demand collection system" other than the
Company's for the sale of airline tickets over the Internet for carriage on one
or more airlines including Warrant Holder and/or any of its subsidiaries. For
example, if in the first Measuring Period, the Company achieves Net Revenue that
would entitle the Warrant Holder to exercise Warrants for 25% of the Shares, the
Warrant Holder will be entitled to exercise such Warrants at all times
thereafter until the Termination Date so long as the Warrant Holder at all times
from the date hereof though the date of such exercise has not participated in
another "demand collection system" for the sale of airline tickets over the
Internet for carriage on one or more airlines including Warrant Holder and/or
any of its subsidiaries. If at any time from the date hereof though to the fifth
5th anniversary of the Issue Date, the Warrant Holder participates in another
"demand collection system" for the sale of airline tickets over the Internet for
carriage on one or more airlines including Warrant Holder and/or any of its
subsidiaries, the Warrant Holder's early exercise rights will terminate

and be of no further force or effect, and such Warrants will become exercisable
on the fifth 5th anniversary of the Issue Date (but no such participation after
an exercise shall invalidate or otherwise have any effect on such exercise, the
Shares issued in connection therewith or any other rights of Warrant Holder
other than early exercise rights).

      5.    Exercise of Purchase Rights.

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

            (b) Net Issue Exercise. Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Exercise Price (at the date of calculation as set forth below),
in lieu of exercising the Warrants for cash, the Warrant Holder may elect to
receive shares equal to the value (as determined below) of the Warrants (or
portion thereof being canceled) by surrender of the Warrants at the principal
office of the Company together with the duly executed Notice of Exercise in
which event the Company shall issue to the Warrant Holder a number of shares of
Common Stock computed using the following formula: X=Y(A-B)/ A WHERE X= the
number of shares of Common Stock to be issued to the Warrant Holder; Y= the
number of shares of the Common Stock purchasable under the Warrants or, if only
a portion of the Warrants is being exercised, the portion of the Warrants being
canceled (at the date of such calculation); A= the fair market value of one
share of the Company's Common Stock (at the date of such calculation); and B=
Exercise Price (at the date of such calculation). For purposes of the above
calculation, fair market value of one share of the Common Stock shall be equal
to the closing trading price of the Company's Common Stock on the day
immediately prior to the date the Notice of Exercise is tendered to the Company.

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

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

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

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

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

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

            (e) Other Changes. If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 10 are not strictly applicable or if strictly applicable, would not
fairly protect the purchase rights of the Warrant Holder in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number of and class of shares available under the Warrants, the Exercise
Price or the application of such provisions, so as to protect the purchase
rights of the Warrant Holder. The adjustment shall be such as will give the
Warrant Holder upon exercise for the same aggregate Exercise Price the total
number, class and kind of shares or other property as the Warrant Holder would
have owned had the Warrants been exercised prior to the event and had the
Warrant Holder continued to hold such shares until after the event requiring
adjustment.

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

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

      11. Representations and Warranties of the Warrant Holder.

      The Warrant Holder hereby represents and warrants to the Company as

<PAGE>

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

conditions of the Warrants, the business of the Company, and to obtain
additional information to such Warrant Holder's satisfaction.

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

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

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

            (b) Exchange, Transfer, Assignment. The Warrants cannot be
exchanged, transferred or assigned otherwise than in accordance with applicable
law. Upon compliance with applicable law and surrender of the Warrants to the
Company with the Assignment Form annexed hereto as Exhibit B duly executed, and
funds sufficient to pay any transfer tax, the Company shall, without charge,
execute and deliver a new Warrant Agreement in the name of the heir, devisee or
assignee named in such instrument of assignment and this Warrant Agreement shall
promptly be canceled. Subject to the terms hereof, the Warrants may be assigned
in whole or in part.

      13. Restricted Securities. The Warrant Holder understands that the
Warrants and the Shares issuable upon vesting and exercise of the Warrants, will
not be registered at the time of their issuance under the Securities Act for the
reason that the sale provided for in this Agreement is exempt pursuant to
Section 4(2) of the Securities Act based on the representations of the warrant
Holder set forth herein. The Warrant Holder represents that it is experienced in
evaluating companies such as the Company, has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment and has the ability to suffer the total loss of the
investment. The Warrant Holder further represents that it has had the
opportunity to ask questions

Agreement) under such Agreement; provided that no registration statement with

                        hereunder shall operate as a waiver thereof, nor shall

                             PREMISES, TERM AND RENT

      1.1. Landlord hereby leases to Tenant and Tenant hereby hires from

place in the United States of America as Landlord may designate, without any
setoff or deduction whatsoever, except such deduction as may be occasioned by

annual rent), and shall be payable twenty (20) days after demand, unless other
payment dates are hereinafter provided.

annual rent or any payment of additional rent for a period of seven (7) days
after such installment or payment shall have become due, Tenant shall pay
interest thereon at the Interest Rate (as such term is defined in Article 22
hereof), from the date when such installment or payment shall have become due to
the date of the payment thereof and such interest shall be deemed additional
rent.

                  (b) If Landlord shall fail to pay when due any amount which is
            uncontested and due to Tenant hereunder for a period of seven (7)
            days after Tenant shall give Landlord a notice thereof, Landlord
            shall pay interest thereon at the Interest Rate (as such term is
            defined in Article 22 hereof), from the date immediately following
            such period to the date of the payment thereof.

<PAGE>

      1.5. If any of the fixed annual rent or additional rent payable under the
terms and provisions of this Lease shall be or become uncollectible, reduced or
required to be refunded because of any Legal Requirement (as such term is
defined in Article 22 hereof), Tenant shall enter into such agreement(s) and
take such other steps (without additional expense to Tenant) as Landlord may
request and as may be legally permissible to permit Landlord to collect the
maximum rents which from time to time during the continuance of such legal rent
restriction may be legally permissible (and not in excess of the amounts
reserved therefor under this Lease). Upon the termination of such legal rent
restriction, (a) the rents shall become and thereafter be payable in accordance
with the amounts reserved herein for the periods following such termination and
(b) Tenant shall pay to Landlord, to the maximum extent legally permissible, an
amount equal to (i) the rents which would have been paid pursuant to this Lease
but for such legal rent restriction less (ii) the rents paid by Tenant during
the period such legal rent restriction was in effect.

                                    ARTICLE 2

                       PREPARATION OF THE DEMISED PREMISES

      2.1. Tenant shall accept the demised premises as is" on the Commencement
Date and Landlord shall not be required to perform any work, install any
fixtures or equipment or render any services to make the Building or the demised
premises ready or suitable for Tenant's use or occupancy. All other

                                 Tax escalation

            (a) The term "Tax Year" shall mean each period of twelve months,
      commencing on the first day of July in which occurs any part of the term
      of this Lease or such other period of twelve months occurring during the
      term of this Lease as hereafter may be duly adopted as the fiscal year for
      real estate tax purposes by the City of Norwalk, Connecticut.

            (b) The term "The Building Project" shall mean the parcel of land
      set forth in Exhibit A of this Lease, on a portion of which are the
      improvements of which the demised premises form a part, with all the
      improvements thereon


                                       3
<PAGE>

      (including without limitation, the office building and parking areas
      erected thereon).

            (c) The term "Comparative Year" shall mean the Tax Year commencing
      on the July 1st immediately preceding the Commencement Date and each
      subsequent Tax Year. If the present use of July 1 to June 30 Tax Year
      shall hereafter be changed, then such changed Tax Year shall be used with
      appropriate adjustment for the transition.

            (d) The term "Taxes" shall mean the total of all real estate and
      other taxes and special, general, extraordinary or other assessments,
      sewer rents, water charges, occupancy taxes and other taxes or charges of
      any kind or nature levied, assessed, imposed or attributable at any time
      by the City of Norwalk, the Town of Darien or any other governmental
      authority (including without limitation any town, city, district, county,
      school district or public transportation authority) upon or against The
      Building Project, and also any tax, assessment, or charge, levied,
      assessed or imposed at any time by any governmental authority in
      connection with the receipt of income or rents from The Building Project
      to the extent that same shall be in lieu of all or a portion of any of the
      aforesaid taxes, assessments or charges, or additions or increases
      thereof. If, due to a future change in the method of taxation or in the
      taxing authority, or for any other reason, a franchise, income, transit,
      profit or other tax or governmental imposition, however designated, shall
      be levied against owners and lessors of real property (as opposed to a tax
      or imposition of general application) and the same shall be levied against
      Landlord in substitution in whole or in part for the Taxes, then such
      franchise, income, transit, profit or other tax or governmental imposition
      shall be deemed to be included within the definition of "Taxes" for the
      purposes hereof. If, by law, any assessment shall be payable in
      installments, then, for the purposes hereof (i) such assessment shall be
      deemed to have been payable in the maximum number of installments
      permitted by law and (ii) there shall be included in Taxes, for each
      Comparative Year in which such installments may be paid, the installments
      of such assessment so becoming payable during such Comparative Year

      during such Comparative Year. Except as provided above, there shall be
      excluded from Taxes all municipal, state and federal income taxes assessed
      against Landlord; corporate franchise taxes imposed against any corporate
      owner of The Building Project; any municipal, state or federal estate,
      succession, inheritance or wealth transfer taxes of Landlord. Taxes shall
      also exclude any interest and/or penalties on delinquent payment of Taxes
      by Landlord; any increases in Taxes which can be directly attributed to
      improvements made to space in the Building which has been previously

      premises), by reference to the notes of the applicable tax assessor; any
      taxes that are allocable to the construction of additional floors to the

            (e) The term "Tax Base Factor" shall mean an amount equal to the
      Taxes for the twelve (12) month period commencing September 1, 1993. To
      the extent that the period for which the Tax Base Factor is to be
      calculated does not correspond with the fiscal year for real estate taxes
      of the jurisdiction to which the same are paid, the Tax Base Factor shall
      be calculated using a weighted average of the Taxes for the fiscal years
      in which such twelve (12) month period occurs (e.g., if the period upon
      which the Tax Base Factor is based includes ten (10) months of one fiscal
      year and two (2) months of another fiscal year, the Tax Base Factor shall
      include 10/12th of the Taxes of the former and 2/12th of the Taxes of the
      latter).

            (f) The term "The Percentage," for purposes of computing tax
      escalation pursuant to this Article, shall mean 40.83 (4O.83%) percent.
      The Percentage has been computed on the basis of a fraction, the numerator
      of which is the rentable square foot area of the demised premises and the
      denominator of which is the rentable square foot area of the office
      building comprising a part of The Building Project. The parties agree that
      the rentable square foot area of the demised premises shall be deemed to
      be 164,739 square feet and that the total rentable square foot area of the
      office building comprising a part of The Building Project shall be deemed
      to be 403,437 square feet.

            (g) The term "Tax Escalation Statement" shall mean a written
      statement (i) setting forth the amount payable by Tenant or Landlord as
      the case may be, for a specified Comparative Year pursuant to this
      Article, (ii) providing such detail as may be necessary to verify the
      basis for the calculation and inclusion of each component of such amount,
      and (iii) accompanied by copies of the tax bills from the taxing
      authorities with respect to The Building Project for the then applicable
      Tax Year(s).

      3.3. (a) In the event that the Taxes payable for any Comparative Year
shall exceed the Tax Base Factor, Tenant shall pay tax escalation to Landlord,
as additional rent for such Comparative Year, in an amount equal to The
Percentage of the excess (such amount being sometimes hereinafter called the
"Tax Escalation Payment"), subject to the provisions of Section 3.12 hereof.
Before or after the start of each Comparative Year, Landlord shall furnish to
Tenant a Tax Escalation Statement of the Taxes payable for such Comparative
Year. If 2)> the Taxes payable for such Comparative Year exceed the Tax Base
Factor, additional rent for such Comparative Year in an amount1 equal to The
Percentage of the excess shall be due from Tenant to Landlord in two equal
installments, on June 1 preceding such Comparative Year and December 1 of such
Comparative Year. If during the term of this Lease, Taxes are required to be
paid (either to the appropriate taxing authorities or as tax escrow payments to
a superior mortgagee) in full or in monthly, quarterly, or other installments,
or on any other date or dates than as presently required (Taxes are currently
due on July 1 and January 1 of each Comparative Year), then at Landlord's
option, the Tax Escalation Payments shall be correspondingly accelerated or
revised so that said Tax Escalation Payments are due 30 days prior to the


                                       5
<PAGE>

date payments are due (to the taxing authorities or the superior mortgagee). The
benefit of any discount for any early payment or prepayment of Taxes shall
accrue solely to the benefit of Landlord and such discount shall not be
subtracted from Taxes. If a Tax Escalation Statement is furnished to Tenant
after the commencement of the Comparative Year in respect of which such Tax
Escalation Statement is rendered, Tenant shall, within twenty (20) days
thereafter pay to Landlord an amount equal to those installments of the total
Tax Escalation Payment payable as provided in this subsection 3.03(a) during the
period prior to the first day of the month next succeeding the month in which
the applicable statement has been furnished.

            (b) Landlord shall be entitled to estimate the Taxes payable with
      respect to any Tax Year in order to make the computation described in
      subsection 3.03(a) above. Any excess amount paid by Tenant or any
      deficiency owed by Tenant based upon such estimate shall be repaid by
      Landlord or paid by Tenant, as the case may be, with interest thereon at
      the Interest Rate computed from the date owed to the payment or repayment
      thereof.

            (c) Tenant shall also pay to Landlord, as additional rent, the
      entire amount of increases in Taxes directly allocable to improvements
      made to the demised premises after the same has been initially improved
      for occupancy to the extent such increases can be attributed by reference
      to the notes of the tax assessor to such improvements. Payments by Tenant
      under this subsection 3.03(c) shall be made as and when Tenant's Tax
      Escalation Payment is due and payable to Landlord under subsection 3.03(a)
      hereof.

      3.4. If, after Tenant shall have made a payment of additional rent under
this Article, the Taxes payable for any Comparative Year on which such payment
of additional rent shall have been based shall be changed, then the amount
payable for that Comparative Year shall be revised to reflect such change and
appropriate adjustments promptly made between Landlord and Tenant. If, after
Tenant shall have made a payment of additional rent under this Article, Landlord
shall receive a refund of any portion of the Taxes payable for any Comparative
Year on which such payment of additional rent shall have been based, as a result
of a reduction of such Taxes by final determination of legal proceedings,
settlement or otherwise, Landlord shall within forty five (45) days after
receiving the refund pay to Tenant and/or credit against the installment(s) of
fixed annual rent and additional rent becoming due during such forty five (45)
day period The Percentage of the net refund, i.e., the amount of the refund less
the reasonable or customary expenses, including payments to attorneys,
appraisers and other experts, incurred by Landlord in connection with such
refund. Only Landlord shall be eligible to institute tax reduction or other
proceedings to reduce the assessed valuation of the Land and the Building.

      3.5. The Tax Escalation Statements to be furnished by Landlord as provided
in this Article shall constitute a final determination as between Landlord and
Tenant of the Tax Escalation Payment for the periods represented thereby unless
Tenant shall, within ninety (90) days after they are furnished, give a notice to
Landlord that it disputes their


                                       6
<PAGE>

accuracy or their appropriateness which notice shall specify the particular
respects in which the Tax Escalation Statement is inaccurate or inappropriate.
Pending the resolution of such dispute, Tenant shall pay additional rent to
Landlord in accordance with the Tax Escalation Statement furnished by Landlord.
Any amounts finally determined in connection with such a dispute to be owed to
Landlord or Tenant as the case may be shall be paid by the applicable party to
the other together with interest thereon at the Interest Rate computed from the
date owed to the payment thereof.

      3.6. In no event shall the fixed annual rent under this Lease be reduced
by virtue of this Article.

      3.7. If the Commencement Date is not the first day of a Comparative Year,
then the additional rent due hereunder for such Comparative Year shall be a
proportionate share of the additional rent for the entire Comparative Year, said
proportionate share to be based upon the length of time that the term of this
Lease shall have been in existence during such Comparative Year. Upon the date
of any expiration or termination of this Lease, (except termination because of
Tenant's default), whether the same be the date hereinabove set forth for the
expiration of the term or any prior or subsequent date, a proportionate share of
said additional rent for the Comparative Year during which such expiration or
termination occurs shall immediately become due and payable by Tenant to
Landlord, if it was not theretofore already billed and paid. Such proportionate
share shall be based upon the length of time that this Lease shall have been in
existence during such Comparative Year. Prior to or promptly after said
expiration or termination, Landlord shall compute the additional rent due from
Tenant, as aforesaid, and Landlord and Tenant shall thereupon make' appropriate
adjustments of amounts then owing.

      3.8. Landlord's and Tenant's obligation to make the adjustments referred
to in Section 3.07 hereof above shall survive any expiration or termination of
this Lease. After the termination of the Lease, the final adjustment for Tax
Escalation pursuant to this Article 3 shall be made as soon as practicable, and
if Landlord retains any moneys of Tenant due to excess payments made by Tenant
hereunder, such excess moneys shall be promptly refunded to Tenant after such
final adjustment has been made with interest thereon if and to the extent that
Section 1.04(b) hereof is applicable thereto.

      3.9. Any delay or failure of Landlord to bill any Tax Escalation Payment
as provided in this Article 3 shall not constitute a waiver of or in any way
impair the continuing obligation of Tenant to make such Tax Escalation Payment,
unless such delay or failure shall continue for more than two (2) years after
the end of the Comparative Year in which such Tax Escalation Payment became due
and payable by Tenant, and thereafter Tenant shall have given Landlord a notice
stating that unless Tenant receives such billing from Landlord within thirty
(30) days from the date of such notice (and such billing is not received within
such thirty (30) day period), such additional Tax Escalation Payment shall be
deemed to have been waived.

      3.10. Landlord shall advise Tenant by notice (hereinafter called the "Tax
Contest Notice") within sixty (60) days after any new assessment or reassessment
by the


                                       7
<PAGE>

City of Norwalk increasing the assessed value of The Building Project
(hereinafter called the "New Assessed Value") whether Landlord intends to
contest such new assessment or reassessment. If Landlord advises Tenant that
Landlord does not intend to contest such new assessment or reassessment,
Landlord agrees that if Tenant shall, at Tenant's sole cost and expense, obtain
and deliver to Landlord within sixty (60) days after the date of the Tax Contest
Notice, an appraisal of The Building Project by a member of the American
Institute of Real Estate Appraisers (or any successor association or body of
comparable standing if such institute is not then in existence) reasonably
acceptable to Landlord, showing that the New Assessed Value determined by the
taxing authorities is more than twelve (12%) percent in excess of what it should
be, then Landlord shall contest such reassessment or new assessment of the New
Assessed Value.

      3.11. (a) Tenant shall pay to Landlord, within twenty (20) days after
Landlord's demand therefor, an amount equal to the reasonable or customary
expenses, including payments to attorneys, appraisers and other experts,
incurred by Landlord in connection with any contest pursuant to Section 3.10
hereof; however, if Landlord shall receive any refund in Taxes as a result of
such contest, Landlord shall, before making any credits or refunds therefrom to
any tenant in the Building, reimburse Tenant (to the extent that such refund or
credit is sufficient therof or) for the expenses paid by Tenant pursuant to this
Section 3.11 and the reasonable expenses incurred by Tenant in obtaining the
appraisal described in Section 3.10 hereof.

            (b) If Landlord shall obtain a reduction of Taxes payable upon or
      against The Building Project for any Comparative Year before Tenant shall
      make Tax Escalation Payments therefor, the Taxes for such Comparative Year
      for the purposes of computing Tenant's Tax Escalation Payment shall
      include an amount equal to the reasonable and customary expenses,
      including payments to attorneys, appraisers and other experts incurred by
      Landlord in obtaining such reduction, but in no event shall the aggregate
      of such expenses included within Taxes as provided herein exceed the
      amount of the reduction obtained thereby.

      3.12. (a) For purposes of this Section 3.12, the following terms shall
have the meanings hereinafter set forth:

            (i) "The First Floor West and Fourth Floor North Percentage" shall
      mean 10.56%;

            (ii) "The Remaining Floors Percentage" shall mean 30.27%; and

            (iii) "Modified Tax Base Factor" shall mean an amount equal to the
      Taxes for the twelve (12) month period commencing on July 1, 1992.

The First Floor West and Fourth Floor North Percentage and the Remaining Floors
Percentage have been computed on the basis of a fraction, the numerator of which
is the rentable square foot area of the First Floor West and Fourth Floor North
portion of the demised premises and the remaining portion of the demised
premises, respectively, and


                                       8
<PAGE>

the denominator of which is the rentable square foot area of the office building
comprising a part of The Building Project. The parties agree that the rentable
square foot area of the First Floor West and Fourth Floor North portion of the
demised premises and the remaining portion of the demised premises shall be
deemed to be 42,609 square feet and 122,130 square feet, respectively, and that
the total rentable square foot area of the office building comprising a part of
The Building Project shall be deemed to be 403,437 square feet.

            (b) Notwithstanding anything to the contrary in this Article 3,
      during the period commencing on the Commencement Date and ending on
      February 29, 1996, the Tax Escalation Payment shall be the sum of:

                  (i) The First Floor West and Fourth Floor North Percentage of
            the excess of the Taxes payable for any Comparative Year over the
            Tax Base Factor; and

                  (ii) The Remaining Floors Percentage of the excess of the
            Taxes payable for any Comparative Year over the Modified Tax Base
            Factor.

            (c) The Tax Escalation Payment for the Comparative Year commencing
      on July 1, 1995 (or such other Comparative Year in which March 1, 1996
      occurs) shall be equal to the sum of (i) the Tax Escalation Payment,
      calculated as provided in this Section 3.12, for the period commencing on
      July 1, 1995 and ending on February 29, 1996, and (ii) the Tax Escalation
      Payment, calculated as otherwise provided in this Article 3 (and without
      reference to the Modified Tax Base Factor), for the balance of such
      Comparative Year. The Tax Escalation Payments for the Comparative Year
      commencing July 1, 1996 and all Comparative Years thereafter shall be
      computed utilizing the Tax Base Factor only and without regard to the
      Modified Tax Base Factor.

                                    ARTICLE 4

                               Expense Escalation

      4.1. Tenant shall pay to Landlord, as additional rent, expense escalation
in accordance with this Article.

      4.2. Definitions: For the purpose of this Article, the following
definitions shall apply:

            (a) The term "Expense Base Factor" shall mean the Expenses for the
      twelve (12) month period commencing September 1, 1993. To the extent that
      the period for which the Expense Base Factor is to be calculated does not
      correspond with the fiscal year that Landlord utilizes to establish
      Expenses with respect to


                                       9
<PAGE>

      The Building Project, the Expense Base Factor shall be calculated using a
      weighted average of the Expenses for the fiscal years in which such twelve
      (12) month period occurs (e.g., if the period upon which the Expense Base
      Factor is based includes eight (8) months of one fiscal year and four (4)
      months of another fiscal year, the Expense Base Factor shall include
      8/12th of the Expenses of the former and 4/12th of the Expenses of the
      latter).

            (b) The term "The Building Project" shall mean the parcel of land
      described in Exhibit A of this Lease, on a portion of which are the
      improvements of which the demised premises form a part, with all the
      improvements thereon (including without limitations, the office building
      and parking areas erected thereon).

            (c) The term "Comparative Year" shall mean the full calendar year in
      which the term of this Lease commences, and each subsequent calendar year.

            (d) The term "The Percentage," for purposes of computing expense
      escalation, shall mean 40.83 (40.83%) percent. The Percentage has been
      computed on the basis of a fraction, the numerator of which is the
      rentable square foot area of the demised premises and the denominator of
      which is the total rentable square foot area of the office building
      comprising a part of The Building Project. The parties agree that the
      rentable square foot area of the demised premises shall be deemed to be
      164,739 and that the total rentable square foot area of the office
      building comprising a part of The Building Project shall be deemed to be
      403,437 square feet.

            (e) The term "Expense Escalation Statement" shall mean a written
      statement setting forth the amount payable by Tenant or Landlord, as the
      case may be, for a specified Comparative Year pursuant to this Article.

            (f) The term "Expenses" shall mean the total amount of all costs and
      expenses incurred or paid by Landlord with respect to and in connection
      with the operation, maintenance and/or repair of The Building Project and
      the curbs and sidewalks adjoining the same, which costs and expenses shall

      painting of non tenanted areas at The Building Project as well as in
      "Common Areas" [as such term is hereinafter defined]); lobby decorations
      and interior and exterior landscape work and maintenance; fire, extended
      coverage, boiler, sprinkler, apparatus, war risk, public liability and
      property damage insurance, rental and plate glass insurance and any
      insurance required by a mortgagee; supplies,

      replacements and improvements which are appropriate for the continued
      operation of The Building Project as a first class office building project

      nature shall be included in the Expense Base Factor); all other costs and
      expenses of operation and maintenance of The Building Project; auditing
      fees necessarily incurred in connection with the maintenance and operation
      of The Building Project; accounting fees incurred in connection with the

      managing agent for the Building shall be an affiliate of Landlord, the
      amount to be included in Expenses thereof or shall be comparable to fees

      comparable to the Building in Fairfield County, Connecticut); the cost for
      a bookkeeper and for an accountant; reasonably incurred professional and
      consulting fees, including legal and audit fees; and association fees or

            included in Expenses for the Comparative Year in which the costs are
            incurred and subsequent Comparative Years, on a straight line basis,
            to the extent that such items are amortized over the shorter of: (x)
            the useful life of such improvement or (y) ten (10) years, with an
            interest factor equal to the prime rate for 90 days unsecured loans
            as


                                       11

            announced from time to time by Chemical Bank of New York at the time
            of Landlord's having incurred said expenditure;

                  (iii) cost of repairs or replacements incurred by reason of
            fire or other casualty (to the extent that Landlord is compensated
            therefor through proceeds of insurance or should be compensated

            pursuant to subsection 9.03(b) of this Lease with deductibles not
            exceeding those which a prudent landlord would maintain under the
            circumstances), or caused by the exercise of the right of eminent
            domain;

                  (iv) except as provided in clause (ii) hereof, interest on and
            amortization of debts;

                  (v) "Taxes" and legal fees incurred in connection with the

                  (viii) except as the same relates to capital expenditures
            which may be included in Expenses as herein provided, depreciation
            or amortization of The Building Project or its contents or
            components;

                  (ix) legal expense incurred in connection with disputes with

                  (xiv) amounts paid to any entity owned by or under common
            ownership with Landlord, but only to the extent of the excess paid
            to such entity over that which would have been paid in the absence
            of such a relationship;


                                       12
<PAGE>



                  (xv) costs or expenses for which Landlord has been
            specifically reimbursed by any tenant, including Tenant, other than
            by payment of a portion of Landlord's operating expenses generally
            or pursuant to any other escalation or similar provision of such
            tenant's lease, or any other party;

                  (xvi) any penalty or fine incurred for non compliance with
            applicable building or fire codes;

                  (xvii) any ground rent payable with respect to a lease of the
            land on which The Building Project is erected;

                  (xviii) franchise, income or other taxes or assessments,
            penalties or fines imposed upon Landlord (excluding taxes payable
            with respect to costs and expenses comprising Expenses); and

                  (xix) the salaries or other compensation of employees of
            Landlord above the level of Building manager.

      If Landlord shall purchase any item of capital equipment or make any
      capital expenditures designed to result in savings or reductions in
      Expenses, then the costs for same shall be included in Expenses for the
      Comparative Year in which the costs are incurred and subsequent
      Comparative Years, on a straight line basis, to the extent that such items
      are amortized over such period of time as reasonably can be estimated as
      the time in which such savings or reductions in Expenses are expected to
      equal Landlord's costs for such capital equipment or capital expenditure,
      with an interest factor equal to the Interest Rate at the time of
      Landlord's having incurred said costs. If Landlord shall lease any such
      item of capital equipment designed to result in savings or reductions in
      Expenses, then the rentals and other costs paid pursuant to such leasing
      shall be included in expenses for the Comparative Years in which they were
      incurred, provided that the charges for any such lease shall be
      essentially constant throughout the term thereof and shall not for any
      Comparative Year exceed the reasonably anticipated savings to be realized
      therefrom.

      If during all or part of any Comparative Year, or any calendar year on
      which the Expense Base Factor or Modified Expense Base Factor is based,
      Landlord shall not furnish any particular item(s) of work or service
      (which would constitute an element of Expense hereunder) to portions of
      The Building Project due to the fact that such portions are not occupied
      or leased, or because such item of work or service is not required or
      desired by the tenant of such portion, or such tenant is itself obtaining
      and providing such item of work or service, or for other reasons, then,
      for the purposes of computing the additional rent payable hereunder, the
      amount of the expenses for such item for such period shall be deemed to be
      increased by an amount equal to the additional operating and maintenance
      expenses which would reasonably have been incurred during such period by


                                       13
<PAGE>

      Landlord if it had at its own expense furnished such item of work or
      services to ninety five (95%) percent of the rentable area of The Building
      Project.

      4.3. (a) If the Expenses for any Comparative Year shall be greater than
the Expense Base Factor, Tenant shall pay to Landlord, as additional rent for
such Comparative Year, in the manner hereinafter provided, an amount equal to
The Percentage of the excess of the Expenses for such Comparative Year over the
Expense Base Factor (such amount being hereinafter called the "Expense
Payment"), subject to the provisions of Section 4.08 hereof.

            (b) Following the expiration of each Comparative Year, Landlord
      shall submit to Tenant an Expense Escalation Statement, certified by
      Landlord, setting forth the Expenses for the preceding Comparative Year
      and the Expense Payment, if any, due to Landlord from Tenant for such
      Comparative Year. The rendition of such Expense Escalation Statement to
      Tenant shall constitute prima facie proof of the accuracy thereof and, if
      such statement shows an Expense Payment due from Tenant to Landlord with
      respect to the preceding Comparative Year then (i) Tenant shall make
      payment of any unpaid portion thereof within twenty (20) days after
      receipt of such Expense Escalation Statement; and (ii) Tenant shall also
      pay to Landlord, as additional rent, within twenty (20) days after receipt
      of such Expense Escalation Statement, an amount equal to the product
      obtained by multiplying the total Expense Payment for the preceding
      Comparative Year by a fraction, the denominator of which shall be 12 and
      the numerator of which shall be the number of months of the current
      Comparative Year which shall have elapsed prior to the first day of the
      month immediately following the rendition of such Expense Escalation
      Statement; and (iii) Tenant shall also pay to Landlord, as additional
      rent, commencing as of the first day of the month immediately following
      the rendition of such Expense Escalation Statement and on the first day of
      each month thereafter until a new Expense Escalation Statement is
      rendered, 1/12th of the total Expense Payment for the preceding
      Comparative Year. The aforesaid monthly payments based on the total
      Expense Payment for the preceding Comparative Year shall be adjusted to
      reflect, as reasonably estimated and specifically set forth in reasonable
      detail in such Expense Escalation Statement by Landlord, increases in
      rates and amounts, for the current Comparative Year, applicable to the
      categories involved in computing Expenses, whenever such increases become
      reasonably known or anticipated prior to or during such current
      Comparative Year. The payments required to be made under clauses (ii) and
      (iii) of this subsection 4.03(b) shall be credited toward the Expense
      Payment due from Tenant for the then current Comparative Year, subject to
      adjustment as and when the Expense Escalation Statement for such current
      Comparative Year is rendered by Landlord.

            (c) The Expense Escalation Statements to be furnished by Landlord
      shall constitute a final determination as between Landlord and Tenant of
      the Expense Payments for the periods represented thereby, unless Tenant
      within one hundred (100) days after they are furnished shall give a notice
      to Landlord that it


                                       14
<PAGE>

      disputes their accuracy or their appropriateness, which notice shall
      specify the particular respects in which the Expense Escalation Statement
      is inaccurate. Pending the resolution of such dispute, Tenant shall pay
      the additional rent to Landlord in accordance with the Expense Escalation
      Statements furnished by Landlord. After payment of said additional rent,
      Tenant shall have the right, during reasonable business hours and upon not
      less than five (5) business days' prior written notice to Landlord, to
      examine Landlord's books and records with respect to the foregoing
      provided such examination is commenced within sixty (60) days and
      concluded within one hundred twenty five (125) days following the
      rendition of the Expense Escalation Statement in question. Any amounts
      finally determined in connection with such a dispute to be owed to
      Landlord or Tenant, as the case may be, shall be paid by the applicable
      party to the other together with interest thereon at the Interest Rate
      computed from the date owed to the payment thereof.

      4.4. In no event shall the fixed annual rent under this Lease be reduced
by virtue of this Article.

      4.5. If the Commencement Date is not the first day of the first
Comparative Year, then the additional rent due hereunder for such first
Comparative Year shall be a proportionate share of said additional rent for the
entire Comparative Year, said proportionate share to be based upon the length of
time that the Lease term shall have been in existence during such first
Comparative Year. Upon the date of any expiration or termination of this Lease
(except termination because of Tenant's default), whether the same be the date
hereinabove set forth for the expiration of the term or any prior or subsequent
date, a proportionate share of said additional rent for the Comparative Year
during which such expiration or termination occurs shall immediately become due
and payable by Tenant to Landlord, if it was not theretofore already billed and
paid. The said proportionate share shall be based upon the length of time that
this Lease shall have been in existence during such Comparative Year. Landlord
shall cause an Expense Escalation Statement for that Comparative Year to be
prepared and furnished to Tenant. Landlord and Tenant shall thereupon make
appropriate adjustments of amounts then owing.

      4.6. Landlord's and Tenant's obligation to make the adjustments referred
to in Section 4.05 hereof shall survive any expiration or termination of this
Lease.

      4.7. Any delay or failure of Landlord in billing any Expense Payment
hereinabove provided shall not constitute a waiver of or in any way impair the
continuing obligation of Tenant to pay such expense escalation hereunder, unless
such delay or failure shall continue for more than two (2) years after the end
of the Comparative Year in which such Expense Payment became due and payable by
Tenant, and thereafter Tenant shall have given Landlord a notice stating that
unless Tenant receives such billing from Landlord within thirty (30) days from
the date of such notice (and such billing is not received within such thirty
(30) day period), such Expense Payment, to the extent not theretofore paid,
shall be deemed to have been waived.


                                       15

      4.8. (a) For purposes of this Section 4.08, the following terms shall have
the meanings hereinafter set forth:

            (i) "The First Floor West and Fourth Floor North Percentage" shall
      mean 10.56%;

            (ii) "The Remaining Floors Percentage" shall mean 30.27%; and

            (iii) "Modified Expense Base Factor" shall mean an amount equal to
      the Expenses for the twelve (12) month period commencing on July 1, 1992.

The First Floor West and Fourth Floor North Percentage and the Remaining Floors
Percentage have been computed on the basis of a fraction, the numerator of which
is the rentable square foot area of the First Floor West and Fourth Floor North
portion of the demised premises and the remaining portion of the demised
premises, respectively, and the denominator of which is the rentable square foot
area of the office building comprising a part of The Building Project. The
parties agree that the rentable square foot area of the First Floor West and
Fourth Floor North portion of the demised premises and the remaining portion of
the demised premises shall be deemed to be 42,609 square feet and 122,130 square
feet, respectively, and that the total rentable square foot area of the office
building comprising a part of The Building Project shall be deemed to be 403,437
square feet.

            (a) Notwithstanding anything to the contrary in this Article 4,
      during the period commencing on the Commencement Date and ending on
      February 29, 1996, the Expense Payment shall be the sum of:

                  (i) The First Floor West and Fourth Floor North Percentage of
            the excess of the Expenses payable for any Comparative Year over the
            Expense Base Factor; and

                  (ii) The Remaining Floors Percentage of the excess of the
            Expenses for any Comparative Year over the Modified Expense Base
            Factor.

      4.9. The Expense Payment for the Comparative Year commencing on January 1,
1996 (or such other Comparative Year in which March 1, 1996 occurs) shall be
equal to the sum of (i) the Expense Payment, calculated as provided in this
Section 4.08, for the period commencing on January 1, 1996 and ending on
February 29, 1996, and (ii) the Expense Payment, calculated as otherwise
provided in this Article 4 (and without reference to the Modified Expense Base
Factor), for the balance of such Comparative Year. The Expense Payments for the
Comparative Year commencing January 1, 1997 and all Comparative Years thereafter
shall be computed utilizing the Expense Base Factor only and without regard to
the Modified Expense Base Factor.

      5.1. The demised premises shall be used solely as and for executive and
general offices and other business activities customarily incidental thereto in
first class office buildings in Fairfield County, Connecticut and, as an
incident thereto, a portion of the demised premises may be used as an exercise
facility or gym exclusively for Tenant's employees, such use to be limited to a
portion of the demised premises of approximately 5,000 rentable square feet and
located on the First C 1st) Floor West of the Building (hereinafter referred to
as the "Exercise Facility") and for no other purposes.

      5.2. Tenant shall not use or permit the use of the demised premises or any
part thereof in any way which would violate any of the covenants, agreements,
terms, provisions and conditions of this Lease or for any unlawful purposes or
in any unlawful manner or in violation of the certificate of occupancy or other
certificate or permit for the demised premises or the Building, and Tenant shall
not suffer or permit the demised premises or any part thereof to be used in any
manner or anything to be done therein or anything to be brought into or kept
therein which, in the reasonable judgment of Landlord, shall in any way impair
the character, reputation or appearance of the Building as a high quality office
building, impair or interfere with any of the Building services or the proper
and economic heating, cleaning, air conditioning or other servicing of the
Building or the demised premises, or impair or interfere with the use of any of
the other areas of the Building by, or occasion discomfort, inconvenience or
annoyance to, any of the other tenants or occupants of the Building. Tenant
shall not install any electrical or other equipment of any kind which, in the
reasonable judgment of Landlord, might cause any impairment or interference with
the operation of electrical equipment installed elsewhere in the Building.

                          ALTERATIONS AND INSTALLATIONS

      6.1.  (a) Tenant shall make no alterations, installations, additions or
            improvements (such work hereinafter collectively referred to as
            "Alterations") in or to the demised premises without Landlord's
            prior written consent and then only by contractors or mechanics
            first approved by Landlord. Notwithstanding the foregoing,
            Landlord's consent shall not be required for non structural
            Alterations in the demised premises costing less than the "Threshold
            Amount" (as such term is hereinafter defined), provided that (i)
            neither the outside appearance, nor the strength of the Building,
            nor any of its structural parts shall be affected; (ii) no part of
            the Building outside of the demised premises shall be physically
            affected, (iii) the proper functioning of any of the mechanical,
            electrical, sanitary and other systems of the Building shall not be
            adversely affected, and the usage of such systems by Tenant shall
            not be increased


                                       17

            except to a de minimis extent, and (iv) prior to commencement of any
            such Alterations, Tenant will give Landlord written notice thereof,
            together with plans and specifications for the work, and will
            otherwise comply with the provisions of this Article. As used in
            this Section 6.01, the term "Threshold Amount" shall mean $100,000
            effective as of the Commencement Date, which amount shall be
            increased effective as of each anniversary of the Commencement Date
            by $5,000. All such Alterations, shall be done at Tenant's sole
            expense and at such times and in such manner as Landlord may from
            time to time reasonably designate. Prior to commencement of
            Alterations, other than Alterations performed to prepare the demised
            premises for Tenant's initial occupancy or Alterations costing less
            than $150,000.00, Tenant shall obtain and deliver to Landlord (i)
            written, unconditional waivers of mechanic's or other liens on the
            real property in which the demised premises are located, signed by
            all architects, engineers, contractors, mechanics and designers to
            become involved in such Alterations (ii) a bond or other security
            reasonably satisfactory to Landlord covering the cost or (iii) proof
            of Tenant's financial responsibility (i.e., financial capacity to
            complete the same and pay therefor) reasonably satisfactory to
            Landlord.

            (b) Tenant's Alterations shall be effected solely in accordance with
      plans and specifications delivered to Landlord or if the Alterations are
      of such a nature that plans and specifications are not customary then upon
      prior notice to Landlord. Tenant shall reimburse Landlord promptly upon
      demand for any reasonable out of pocket costs and expenses incurred by
      Landlord in connection with Landlord's review of such Tenant's plans and
      specifications. As to Alterations for which Landlord's approval is
      required, (i) Landlord will not unreasonably withhold or delay its consent
      for nonstructural Alterations (provided they will not affect the outside
      of the Building or adversely affect the Building's structure, electrical,
      HVAC, plumbing or mechanical systems) and (ii) all such Alterations shall
      be solely effected in accordance with plans and specifications approved by
      Landlord (except that de minimis variations therefrom shall not de deemed
      a violation hereof). Landlord hereby approves Tenant's installation of
      operating windows in the area of the demised premises indicated in the
      plans annexed hereto as Exhibit J provided same is performed in accordance
      with the provisions hereof and such windows are, in Landlord's reasonable
      judgment, consistent in appearance and quality with the adjacent windows
      of the Building.

            (c) Any such approved Alterations shall be performed in accordance
      with the foregoing and the following provisions of this Article 6:

                  (1) All Alterations shall be done in a good and workmanlike
            manner.


                                       18

                  (2) (A) In the event Tenant shall employ any contractor to do
            in the demised premises any Alterations permitted by this Lease,
            such contractor and any subcontractor shall agree to employ only
            such labor as will not result in jurisdictional disputes or strikes
            or result in causing disharmony with other workers employed at the
            Building. Tenant will inform Landlord in writing of the names of any
            contractor or subcontractor Tenant proposes to use in the demised
            premises at least ten (10) days prior to the beginning of work by
            such contractor or subcontractor, but such information given to
            Landlord shall in no way constitute Landlord's approval of such
            contractor or subcontractor.

                  (B) Tenant covenants and agrees to pay to the contractors, as
            the work progresses, the entire cost of supplying the materials and
            performing the work shown on Tenant's approved plans and
            specifications except with respect to such portion of any
            contractor's work which is being contested by Tenant in good faith.

               (3) All such Alterations shall be effected in compliance with all
          applicable laws, ordinances, rules and regulations of governmental
          bodies having or asserting jurisdiction in the demised premises.
          Tenant shall also be responsible for obtaining all Building Department
          sign-offs, inspection certificates and any permits required to be
          issued by any governmental entity having jurisdiction thereover. As
          and when required by law, Landlord shall reasonably cooperate with
          Tenant in obtaining such sign-offs, inspection certificates and
          permits provided Landlord shall not incur any liability or expense
          thereby.

               (4) Tenant shall keep the Building and the demised premises free
          and clear of all liens for any work or material claimed to have been
          furnished to Tenant or to the demised premises on Tenant's behalf, and
          all work to be performed by Tenant shall be done in a manner which
          will not unreasonably interfere with or disturb other tenants or
          occupants of the Building.

               (5) During the progress of the work to be done by Tenant, said
          work shall be subject to inspection by representatives of Landlord
          which shall be permitted access and the opportunity to inspect, at all
          reasonable times, but this provision shall not in any way whatsoever
          create any obligation on Landlord to conduct such an inspection or
          create any obligations or liability (or relieve Tenant of any
          obligations under this Lease) in the event Landlord does conduct such
          an inspection.

               (6) Prior to commencement of any work, Tenant shall furnish to
          Landlord certificates evidencing the existence of:


                                       19
<PAGE>

                  (i) worker's compensation insurance covering all persons
            employed for such work; and

                  (ii) reasonable comprehensive general liability and property
            damage insurance naming Landlord, its designees and Tenant as
            insureds, with coverage of at least $3,000,000 combined single
            limit.

Notice is hereby given that Landlord shall not be liable for any labor or
materials furnished or to be furnished to Tenant upon credit, and that no
mechanic's or other lien for any such labor or materials shall attach to or
affect the reversion or other estate or interest of Landlord in and to the
demised premises.

      6.2. Any mechanic's lien, filed against the demised premises or the
Building for work claimed to have been done for or materials claimed to have
been furnished to Tenant shall be discharged by Tenant at its expense within
thirty C30) days after notice of such filing, by payment, filing of the bond
required by law or otherwise.

      6.3. All Alterations made and installed by Landlord shall be the property
of Landlord and shall remain upon and be surrendered with the demised premises
as a part thereof at the end of the term of this Lease.

      6.4. All Alterations, including, without limitation, any interior
staircases, elevators or operable windows, made and installed by Tenant, or at
Tenant's expense, upon or in the demised premises which are of a permanent
nature and which cannot be removed without damage to the demised premises or
Building shall become and be the property of Landlord, and shall remain upon and
be surrendered with the demised premises as a part thereof at the end of the
term of this Lease, except that Landlord shall have the right 'and privilege at
any time up to six (6) months prior to the expiration of the term of the Lease
to serve notice upon Tenant that any of such Alterations which is of a non
building standard nature (hereinafter called a "Non Standard Alteration"),
including operable windows, stairways, lifts or elevators, vaults, raised floors
or other structural supports and other installations which are unusually
difficult or costly to remove, shall be removed and, in the event of service of
such notice, Tenant will, at Tenant's cost and expense not to exceed
$150,000.00, remove the same in accordance with such request, and restore the
affected portion(s) of the demised premises to their original condition,
ordinary wear and tear and casualty excepted. Notwithstanding the foregoing,
Landlord may not require Tenant to remove any Non Standard Alteration if (i)
Tenant's request for Landlord's consent to such Non Standard Alteration (x)
makes specific reference to the provisions set forth in this sentence and (y)
requests Landlord to advise Tenant whether Landlord wishes to reserve its right
to require Tenant to remove the same and (ii) Landlord's right to such removal
is not expressly reserved in Landlord's consent to said Non--Standard
Alteration.

      6.5. Where furnished by or at the expense of Tenant all furniture,
furnishings and trade fixtures, including without limitation, murals, business
machines and equip-


                                       20
<PAGE>

ment, counters, screens, grille work, special paneled doors, cages, partitions,
metal railings, closets, paneling, lighting fixtures and equipment, drinking
fountains, refrigeration and air handling equipment, and any other movable
property shall remain the property of Tenant which may at its option remove all
or any part thereof at any time prior to the expiration of the term of this
Lease. In case Tenant shall decide not to remove any part of such property,
Tenant shall notify Landlord in writing not less than three C3) months prior to
the expiration of the term of this Lease, specifying the items of property which
it has decided not to remove. If, within thirty C30) days after the service of
such notice, Landlord shall request Tenant to remove any of the said property,
Tenant shall at its expense remove the same in accordance with such request. As
to such property which Landlord does not request Tenant to remove, the same
shall be, if left by Tenant, deemed abandoned by Tenant and thereupon the same
shall become the property of Landlord.

      6.6. If any Alterations or other property which Tenant shall have the
right to remove or be requested by Landlord to remove as provided in Sections
6.04 and 6.05 hereof (herein in this Section 6.06 called the "Property") are not
removed on or prior to the expiration of the term of this Lease, Landlord shall
have the right to remove the Property and to dispose of the same without
accountability to Tenant and at the sole cost and expense of Tenant. In case of
any damage to the demised premises or the Building resulting from the removal of
the Property, Tenant shall repair such damage or, in default thereof, shall
reimburse Landlord for Landlord's cost in repairing such damage. This obligation
shall survive any termination of this Lease.

      6.7. Tenant shall keep records of Tenant's Alterations, costing in excess
of $5,000, and of the cost thereof. Tenant shall, within 45 days after demand by
Landlord, furnish to Landlord copies of such records and cost if Landlord shall
require same in connection with any proceeding to reduce the assessed valuation
of the Building or any other tax or charge, or in connection with any proceeding
instituted pursuant to Article 13 hereof.

                                    ARTICLE 7

                                     REPAIRS

      7.1. Tenant shall, at its sole cost and expense, make such repairs to the
demised premises and the fixtures and appurtenances therein as are necessitated
by the act, omission, occupancy or negligence of Tenant or by normal wear and
tear or by the use of the demised premises in a manner contrary to the purposes
for which same are leased to Tenant or the performance of Alterations by or for
Tenant, as and when needed to preserve them in good working order and condition.
Except as otherwise provided in Section 9.04 hereof, all damage or injury to the
demised premises and to its fixtures, appurtenances and equipment or to the
Building or to its fixtures, appurtenances and equipment caused by Tenant moving
property in or out of the Building or by installation or removal of furniture,
fixtures or other property, shall be repaired, restored or replaced promptly by
Tenant at its sole cost and expense, which repairs, restorations and
replacements shall be in quality and class equal to the original work or
installations but Tenant


                                       21
<PAGE>

shall not be responsible and Landlord shall be responsible for any such repairs,
restorations or replacements as are required by Landlord's negligence or willful
misconduct except to the extent that Tenant shall be compensated therefor by the
proceeds of insurance or would be compensated thereof or if it had obtained the
insurance coverage required under Article 9 hereof. If Tenant fails to make such
repairs, restoration or replacements for which Tenant is responsible hereunder,
then, upon ten (10) days prior notice (except that no such notice shall be
required in case of an emergency), same may be made by Landlord at the expense
of Tenant and such expense shall be collectible as additional rent and shall be
paid by Tenant within 20 days after rendition of a bill therefor.

The exterior walls of the Building, the portions of any window sills outside the
windows, and the windows are not part of the premises demised by this Lease and
Landlord reserves all rights to such parts of the Building.

      7.2. Tenant shall not place a load upon any floor of the demised premises
exceeding the floor load per square foot area which such floor was designed to
carry (i.e. 100 pounds per square foot live load on the ground floor and 50
pounds per square foot live load and 20 pounds per square foot dead load on all
other floors) and which is allowed by law, and if Tenant shall desire a floor
load in excess of such floor load, Landlord agrees (provided Landlord's
architects, in their sole discretion, find that the work necessary to increase
such floor load does not adversely affect the structure of the Building, and
further provided that such work will not interfere with the amount or
availability of any space adjoining alongside, above or below the demised
premises, or interfere with the occupancy of other tenants in the Building), to
strengthen and reinforce the same so as to give the live load desired, provided
Tenant shall submit to Landlord the plans showing the locations of and the
desired floor live load for the areas in question and provided further that
Tenant shall agree to pay for or reimburse Landlord on demand for the cost of
such strengthening and reinforcement as well as any other costs to and expenses
of Landlord occasioned by or resulting from such strengthening or reinforcement.

      7.3. Business machines and mechanical equipment used by Tenant which cause
vibration, noise, cold or heat that may be transmitted to the Building structure
or to any leased space to such a degree as to be objectionable to Landlord or to
any other tenant in the Building shall be placed and maintained by Tenant at its
expense in settings of cork, rubber or spring type vibration eliminators
sufficient to absorb and prevent such vibration or noise, or prevent
transmission of such cold or heat. The parties hereto recognize that the
operation of elevators, air conditioning and heating equipment may cause some
vibration, noise, heat or cold which may be transmitted to other parts of the
Building and demised premises. Landlord shall be under no obligation to endeavor
to reduce such vibration, noise, heat or cold beyond what is customary in
current good building practice for buildings of the same type as the Building.

      7.4. Except as otherwise specifically provided in this Lease, there shall
be no allowance to Tenant for a diminution of rental value and no liability on
the part of


                                       22
<PAGE>

Landlord by reason of inconvenience, annoyance or injury to business arising
from the making of any repairs, alterations, additions or improvements in or to
any portion of the Building or the demised premises or in or to fixtures,
appurtenances or equipment thereof. Landlord shall exercise reasonable diligence
(which shall include consultation with Tenant) in making any such repairs,
alterations, additions or improvements so as to minimize any interference with
Tenant's business operations, but shall not be required to perform the same on
an overtime or premium pay basis.

      7.5. Landlord shall, at its expense (subject to reimbursement pursuant to
the provisions of Article 4 hereof) keep and maintain the Building Project,
including the landscaping of the Land and its fixtures, appurtenances and
facilities serving the demised premises, including but not limited to, the
parking areas utilized by Tenant, the roof of the demised premises and the
atrium portion of the Building and the structure immediately adjacent or
contiguous to the demised premises, the electrical, heating, ventilation, air
conditioning, plumbing and mechanical systems (including heat pumps) directly
serving the demised premises to the main distribution duct serving the demised
premises (i.e., those portions of such systems that service parts of the
Building other than or in addition to the demised premises), and the windows of
the demised premises, in good condition and repair in accordance with the
standards appropriate to a first class office building in Fairfield County,
Connecticut, and make all repairs, restorations and replacements, structural and
otherwise, interior and exterior, as and when needed in or about the demised
premises, except for those repairs for which Tenant is responsible pursuant to
the provisions of this Lease.

      7.6. Except in case of emergency, Landlord shall give Tenant at least
seven (7) days prior notice of any entry, repair, alteration, addition or
improvement by Landlord under this Article 7 or Article 10 or 15 hereof, which

business in the demised premises.

                                    ARTICLE 8

                               REQUIREMENTS OF LAW

      8.1. Tenant shall, at Tenant's sole cost and expense, comply with all
laws, orders and regulations of federal, state, county and municipal
authorities, and with any direction of any public officer or officers, pursuant
to law, which shall impose any violation, order or duty upon Landlord or Tenant
with respect to the demised premises, or the use or occupation thereof. Nothing
contained in this Section 8.01 shall require Tenant to perform structural
alterations in or to the demised premises the requirement for which does not
arise from Tenant's use or manner of use of the demised premises. Such
structural alterations for which Tenant is not responsible hereunder shall be
the responsibility of Landlord.

      8.2. Notwithstanding the provisions of Section 8.01 hereof, Tenant, at its
own cost and expense, in its name and/or (whenever necessary) Landlord's name,
may contest, in any manner permitted by law (including appeals to a court, or
governmental depart-


                                       23
<PAGE>

ment or authority having jurisdiction in the matter), the validity or the
enforcement of any governmental act, regulation or directive with which Tenant
is required to comply pursuant to this Lease, and may defer compliance therewith
provided that:

            (a) such non compliance shall not subject Landlord to criminal
      prosecution or subject the Land and/or Building to lien or sale;

            (b) such non compliance shall not be in violation of any fee
      mortgage, or of any ground or underlying lease or any mortgage thereon;

            (c) Tenant shall first deliver to Landlord a surety bond issued by a
      surety company of recognized responsibility, or other security
      satisfactory to Landlord, indemnifying and protecting Landlord against any
      loss or injury by reason of such non--compliance; and

            (d) Tenant shall promptly and diligently prosecute such contest.

            Landlord, without expense or liability to it, shall cooperate with
      Tenant and execute any documents or pleadings required for such purpose,
      provided that Landlord shall reasonably be satisfied that the facts set
      forth in any such documents or pleadings are accurate.

      8.3. Landlord has delivered to Tenant a copy of the asbestos inspection
report it has obtained with regard to the demised premises. Notwithstanding
anything contained herein to the contrary, in the event at any time during the
term of this Lease asbestos is discovered in the demised premises which is
required by applicable law to be removed or encapsulated, then, unless the same
has been introduced into the demised premises by Tenant or its agents,
contractors or employees, Landlord shall remove or encapsulate same as required
by applicable law at Landlord's sole cost and expense.

      8.4. Landlord represents that, as of the date hereof, Landlord has
received no notices of violations of any Legal Requirements affecting The
Building Project which (i) would materially and adversely affect Tenant's use of
the demised premises and (ii) have not been cured.

                                    ARTICLE 9

                    INSURANCE, LOSS, REIMBURSEMENT, LIABILITY

      9.1. Tenant shall not violate, or permit the violation of, any condition
imposed by any insurance policy then issued in respect to The Building Project
and/or the property therein and shall not do, or permit anything to be done, or
keep or permit anything to be kept in the demised premises which would subject
Landlord to any liability or responsibility for bodily injury or death or
property damage, or which would increase any insurance rate in respect to The
Building Project or the property therein over the rate

                                       24
<PAGE>

which would otherwise then be in effect or which would result in insurance
companies of good standing refusing to insure The Building Project or the
property therein in amounts reasonably satisfactory to Landlord, or which would
result in the cancellation of or the assertion of any defense by the insurer in
whole or in part to claims under any policy of insurance in respect of The
Building Project or the property therein.

      9.2. If, by reason of any failure of Tenant to comply with the provisions
of Section 8.01 or Section 9.01, the premiums on Landlord's insurance on The
Building Project and/or equipment or property therein shall be higher than they
otherwise would be for normal general and executive office use, Tenant shall
reimburse Landlord, within forty five (45) days after Landlord's demand
therefor, for that part of such premiums attributable to such failure on the
part of Tenant. A schedule or "make up" of rates for The Building Project or the
demised premises, as the case may be, issued by the applicable fire insurance
rating organization or other similar body making rates for insurance for The
Building Project or the demised premises, as the case may be, shall be
conclusive evidence of the facts therein stated and of the several items and
charges in the insurance rate then applicable to The Building Project or the
demised premises, as the case may be.

      9.3. (a) Tenant, at its expense, shall maintain at all times during the
term of this Lease (i) "all risk" property insurance covering Tenant's property
and improvements and betterments to a limit of not less than 80% of the
replacement cost thereof and (ii) comprehensive general liability insurance,
including contractual liability, in respect of the demised premises and the
conduct or operation of business therein, with Landlord and its managing agent,
if any, and any lessor of any ground or underlying lease or the holder of any
mortgage (as the case may be) whose name and address shall have been furnished
to Tenant, as additional insureds, with limits of not less than $3,000,000
combined single limit bodily injury and property damage liability. The limits of
such insurance shall not limit the liability of Tenant hereunder. Tenant shall
deliver to Landlord and any additional insureds such fully paid for policies or
certificates of insurance in form satisfactory to Landlord issued by the
insurance company or its authorized agent, at least ten (10) days before the
Commencement Date. Tenant shall procure and pay for renewals of such insurance
from time to time before the expiration thereof, and Tenant shall deliver to
Landlord and any additional insured such renewal policy at least thirty (30)
days before the expiration of any existing policy. All such policies shall be
issued by companies licensed to do business in Connecticut and rated by Best's
Insurance Reports or any successor publication of comparable standing, and
carrying a rating of A XII or better or the then equivalent of such rating.

            (b) Landlord shall maintain at all times during the term of this
      Lease, "all risk" property insurance (subject to reasonable deductible
      amounts) covering The Building Project and Landlord's property therein, in
      such amounts as may be required for the repair or restoration thereof
      without co insurance. The foregoing requirement shall not apply to the
      Landlord named herein (nor any successor landlord hereunder) so long as
      its securities are rated as "investment grade" by Moody's, Standard &
      Poor's or another national rating agency and which shall maintain one or
      more separate funds and reserves as and for insurance of its


                                       25
<PAGE>

      property generally (and including The Building Project) in reasonably
      appropriate amounts taking into account usually covered risks.

      9.4. Each party agrees to have included in each of its insurance policies
(insuring The Building Project and Landlord's property therein in the case of
Landlord, and insuring Tenant's property and improvements and betterments in the
demised premises and business interruption, in the case of Tenant, against loss,
damage or destruction by fire or other casualty) a waiver of the insurer's right
of subrogation against the other party during the term of this Lease or, if such
waiver should be unobtainable or unenforceable, (i) an express agreement that
such policy shall not be invalidated if the assured waives the right of recovery
against any party responsible for a casualty covered by the policy before the
casualty, or (ii) any other form of permission for the release of the other
party. If such waiver, agreement or permission shall not be, or shall cease to
be, obtainable from either party's then current insurance company, the insured
party shall so notify the other party promptly after learning thereof, and shall
use its best efforts to obtain the same from another insurance company described
in Section 9.03 hereof. Each party hereby releases the other party, with respect
to any claim (including a claim for negligence) which it might otherwise have
against the other party, for loss, damage or destruction with respect to its
property and, in the case of Tenant, loss of business, occurring during the term
of this Lease to the extent to which it is insured under a policy or policies
containing a waiver of subrogation or permission to release liability, as
provided in the preceding subdivisions of this section. If, notwithstanding the
recovery of insurance proceeds by either party for loss, damage or destruction
of its property, the other party is liable to the first party with respect
thereto or is obligated under this Lease to make replacement, repair or
restoration or payments then, provided the first party's right of full recovery
under its insurance policies is not thereby prejudiced or otherwise adversely
affected, the amount of the net proceeds of the first party's insurance against
such loss, damage or destruction shall be offset against the second party's
liability to the first party therefor, or shall be made available to the second
party to pay for replacement, repair or restoration, as the case may be. Nothing
contained in this section shall be deemed to relieve either party of any duty
imposed elsewhere in this Lease to repair, replace, restore or rebuild provided
for elsewhere in this Lease.

      9.5. Landlord may from time to time, but not more frequently than once
every three years, in the exercise of its reasonable judgment, require that the
amount of comprehensive general liability insurance to be maintained by Tenant
under Section 9.03 be increased, so that the amount thereof adequately protects
Landlord's interest, using industry standards for comparable office space in
Fairfield County, Connecticut.

      9.6. Landlord or its agents shall not be liable for any injury or damage
to persons or property resulting from fire, explosion, falling plaster, steam,
gas, electricity, water, rain or snow or leaks from any part of the Building, or
from the pipes, appliances or plumbing works or from the roof, street or
subsurface or from any other place or by dampness or by any other cause of
whatsoever nature, unless any of the foregoing shall be caused by or due to the
negligence of Landlord, its agents or employees.

      9.7. Landlord or its agents shall not be liable for any damage which
Tenant may sustain, if at any time any window of the demised premises is broken,
or temporarily closed, darkened or bricked up for any reason whatsoever, or
permanently closed, darkened or bricked up pursuant to a Legal Requirement (as
defined in Article 22 hereof), and Tenant shall not be entitled to any
compensation therefor or abatement of rent or to any release from any of
Tenant's obligations under this Lease, nor shall the same constitute an
eviction.

      9.8. Tenant shall reimburse Landlord for all expenses, damages or fines
incurred or suffered by Landlord, by reason of any breach, violation or non
performance by Tenant, or its agents, servants or employees, of any covenant or
provision of this Lease, or by reason of damage to persons or property caused by
moving property of or for Tenant in or out of the Building, or by the
installation or removal of furniture or other property of or for Tenant except
as provided in Section 6.05 of this Lease, or by reason of or arising out of the
carelessness, negligence or improper conduct of Tenant, or its agents, servants
or employees, in the use or occupancy of the demised premises. Subject to the
provisions of Section 8.02 hereof, where applicable, Tenant shall have the
right, at Tenant's own cost and expense, to participate in the defense of any
action or proceeding brought against Landlord, and in negotiations for
settlement thereof if, pursuant to this Section 9.08, Tenant would be obligated
to reimburse Landlord for expenses, damages or fines incurred or suffered by
Landlord.

      9.9. Tenant shall give Landlord notice in case of fire or accidents in the
demised premises promptly after Tenant is aware of such event.

      9.10. Tenant agrees to look solely to Landlord's estate and interest in
the Building, or the lease of the Building, or of The Building Project (as such
term is defined in subsection 3.02(b) hereof) and the demised premises, for the
satisfaction of any right or remedy of Tenant for the collection of a judgment
(or other judicial process) requiring the payment of money by Landlord, in the
event of any liability by Landlord, and no other property or assets of Landlord
shall be subject to levy, execution, attachment, or other enforcement procedure
for the satisfaction of Tenants remedies under or with respect to this Lease,
the relationship of Landlord and Tenant hereunder, or Tenant's use and occupancy
of the demised premises, or any other liability of Landlord to Tenant.

                         ADJACENT EXCAVATION -- SHORING

      10.1. If an excavation or other substructure work shall be made upon land
adjacent to the Building, or shall be authorized to be made, Tenant shall afford
to the person causing or authorized to cause such excavation, license to enter
upon the demised premises for the purpose of doing such work as shall be
necessary to preserve the wall of or the Building of which the demised premises
form a part from injury or damage and to support the same by proper foundations
without any claim for damages or indemnity against Landlord, or diminution or
abatement of rent unless due to Landlord's gross


                                       27
<PAGE>

negligence. Landlord shall use its reasonable efforts to minimize any
inconvenience to Tenant or any interruption of Tenant's business caused by any
such entry provided, however, that in no event shall Landlord be required to
incur overtime or premium pay charges in connection therewith. The provisions of
Section 7.06 hereof shall apply to Landlord's entry hereunder.

                                   ARTICLE 11

                    ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

      11.1. (a)   Tenant shall not (1) assign or otherwise transfer this
                  Lease or the term and estate hereby granted, (2) sublet the
                  demised premises or any part thereof or allow the same to be
                  used or occupied by others or in violation of Article 5
                  hereof, (3) mortgage, pledge or encumber this Lease or the
                  demised premises or any part thereof in any manner by reason
                  of any act or omission on the part of Tenant, or (4)
                  advertise, or authorize a broker to advertise, for a subtenant
                  or an assignee, without, in each instance, obtaining the prior
                  consent of Landlord, except as otherwise expressly provided in
                  this Article 11. Landlord agrees that it will not unreasonably
                  withhold its consent to Tenant's advertisement or Tenant's
                  authorization of a broker's advertisement for a subtenant or
                  assignee provided Tenant shall have complied with the
                  provisions of Section 11.05 hereof and Landlord shall not have
                  exercised any of the rights granted therein. For purposes of
                  this Article 11, (i) the transfer of a majority of the issued
                  and outstanding capital stock of any corporate tenant, or of a
                  corporate subtenant, or the transfer of a majority of the
                  total interest in any partnership tenant or subtenant, however
                  accomplished, whether in a single transaction or in a series
                  of related or unrelated transactions, shall be deemed an
                  assignment of this Lease, or of such sublease, as the case may
                  be, except that the transfer of the outstanding capital stock
                  of any corporate tenant, or subtenant, shall be deemed not to
                  include the sale of such stock by persons or parties, through
                  the "over the counter market" or through any recognized stock
                  exchange, (ii) any agreement whereby a third party takes over
                  the obligations of Tenant under the Lease shall be deemed an
                  assignment of this Lease, (iii) any person or legal
                  representative of Tenant, to whom Tenant's interest under this
                  Lease passes by operation of law, or otherwise, shall be bound
                  by the provisions of this Article 11, and (iv) a modification,
                  amendment or extension of a sublease shall be deemed a
                  sublease.

          (b) If Tenant intends to assign this Lease or sublease the demised
     premises or any portion thereof (other than by an assignment or sublease
     contemplated by Section 11.02 hereof), Tenant shall first comply with the
     provisions of Section 11.05 hereof and Landlord shall have the rights
     described therein. If


                                       28
<PAGE>

      Landlord does not exercise any of its rights under Section 11.05 hereof
      then, provided Tenant shall have complied with the provisions of this
      Article 11, Landlord shall not unreasonably withhold or delay its consent
      to an assignment of this Lease or a sublease of the demised premises as
      more specifically set forth in Section 11.07 hereof. The provisions of
      this subsection 11.01(b) are meant to be a summary only of the provisions
      of this Article 11 and this subsection 11.01(b) in no way shall limit the
      scope of this Article 11 nor the intent or application of any provision
      hereof. In the event of any conflict between the provisions of this
      subsection 11.01(b) and the other provisions of this Article 11, such
      other provisions shall prevail.

     11.2. The provisions of Section 11.01 hereof shall not apply to
transactions with a corporation into or with which Tenant is merged or
consolidated or with an entity to which substantially all of Tenant's assets or
all or a majority of Tenant's stock are transferred (provided such merger or
transfer of stock or assets is for a good business purpose and not principally
for the purpose of transferring the leasehold estate created hereby, and
provided further, that the assignee has a net worth at least equal to or in
excess of the net worth of Tenant immediately prior to such merger or transfer,
such net worth to be calculated in accordance with generally accepted accounting
principles consistently applied) or, if Tenant is a partnership, with a
successor partnership, nor shall the provisions of clauses (l) and (2) of
Section 11.01 apply to transactions with any person, corporation, partnership,
joint venture or other entity which, directly or indirectly controls, is
controlled by or is under common control with the Tenant named herein (each
named hereinafter referred to as an "Affiliate of Tenant"). For the purposes of
the foregoing, "control" shall mean ownership of a majority of the legal and
beneficial interest in such corporation, together with the ability to direct the
management, affairs and operations thereof. Any transfer or cessation of control
over any Affiliate to which this Lease is assigned shall constitute an
assignment of this Lease to which all of the provisions of this Article 11,
other than the provisions of this Section 11.02, shall apply.

     11.3. Any assignment or transfer made hereunder, shall be made only if, and
shall not be effective until, the assignee shall execute, acknowledge and
deliver to Landlord a recordable agreement, in form and substance reasonably
satisfactory to Landlord, whereby the assignee shall assume the obligations and
performance of this Lease and agree to be personally bound by and upon all of
the covenants, agreements, terms, provisions and conditions hereof on the part
of Tenant to be performed or observed and whereby the assignee shall agree that
the provisions of this Article 11 shall, notwithstanding such an assignment or
transfer, continue to be binding upon it in the future. Tenant covenants that,
notwithstanding any assignment or transfer of this Lease, whether or not in
violation of the provisions of this Lease, and notwithstanding the acceptance of
fixed annual rent by Landlord from an assignee or transferee or any other party,
Tenant shall remain fully and primarily liable for the payment of the fixed
annual rent and additional rent due and to become due under this Lease and for
the performance of all of the covenants, agreements, terms, provisions and
conditions of this Lease on the part of Tenant to be performed or observed.


                                       29
<PAGE>

     11.4. The liability of Tenant, and the due performance by Tenant of the
obligations on its part to be performed under this Lease, shall not be
discharged, released or impaired in any respect by an agreement or stipulation
made by Landlord or any grantee or assignee of Landlord by way of mortgage, or
otherwise, extending the time of, or modifying any of the obligations contained
in this Lease, or by any waiver or failure of Landlord to enforce any of the
obligations on Tenant's part to be performed under this Lease, and Tenant shall
continue liable hereunder. If any such agreement or modification operates to
increase the obligations of a tenant under this Lease, the liability under this
Section 11.04 of the tenant named in the Lease or any of its successors in
interest, (unless such party shall have expressly consented in writing to such
agreement or modification) shall continue to be no greater than if such
agreement or modification had not been made. To charge Tenant named in this
Lease and its successors in interest, no demand or notice of any default shall
be required. Tenant and each of its successors in interest hereby expressly
waive any such demand or notice.

     11.5.  (a)   If Tenant shall have a bona fide intention to (i) assign this
                  Lease, other than by an assignment contemplated by Section
                  11.02 hereof, or (ii) sublet all or substantially all (as such
                  term is hereinafter defined) of the demised premises other
                  than by a sublease contemplated by Section 11.02 hereof, then
                  Tenant shall first give notice to Landlord of such fact and of
                  the effective date of the proposed assignment or of the
                  commencement of the term of the proposed sublease and if
                  applicable, the area of the demised premises proposed to be
                  sublet, and Landlord shall then have the right to elect, by
                  notifying Tenant within forty five (45) days of receipt of
                  such notice, to (i) terminate this Lease, as of the intended
                  effective date of such proposed assignment or the commencement
                  of the term of the proposed sublease, as the case may be, (ii)
                  accept an assignment of this Lease from Tenant to Landlord,
                  and Tenant shall then promptly execute and deliver to
                  Landlord, in form reasonably satisfactory to Landlord's
                  counsel (which shall provide in part that no merger of
                  leasehold interests shall occur), an assignment which shall be
                  effective as of the effective date of such assignment as
                  aforesaid, or (iii) accept a sublet of the demised premises in
                  accordance with the provisions of subsection 11.05(c) of this
                  Lease. For the purposes of this Article 11, a sublease of
                  substantially all of the demised premises shall be a sublease
                  which results in Tenant and Affiliates of Tenant occupying
                  less than one (l) full floor of a Wing of the Building.

          (b) If Tenant shall have a bona fide intention to sublet less than
     substantially all of the demised premises, other than by a sublease
     contemplated by Section 11.02 hereof, Tenant shall first give notice to
     Landlord of such fact and of the area it proposes to sublet and for what
     term. Such notice shall be deemed an offer by Tenant whereby Landlord may
     elect within thirty (30) days of such notice with respect to a sublease of
     less than 30,000 rentable square feet, and otherwise


                                       30
<PAGE>

      within forty-five (45) days of such notice, to (i) accept a sublease from
      Tenant with respect to the portion of the demised premises proposed to be
      sublet (hereinafter sometimes called the "Leaseback Area") for the term
      specified in Tenant's notice, or (ii) with respect to a subletting of
      Leaseback Areas for the remainder of the term or substantially all of the
      remainder of the term of this Lease, terminate the Lease with respect to
      such Leaseback Area.

            (c) If Landlord should elect to have Tenant execute and deliver a
      sublease pursuant to any of the provisions of this Section 11.05, said
      sublease shall be in a form reasonably satisfactory to Landlord's counsel
      and on all the terms contained in this Lease, except that:

                  (l) it shall permit Landlord to make further subleases of all
            or any part of the demised premises or the Leaseback Area as the
            case may be and (at no cost or expense to Tenant) to make and
            authorize any and all changes, alterations, installations and
            improvements in such space as Landlord may deem necessary for such
            subletting, at Landlord's expense provided, however, that in the
            event Landlord shall desire to alter the Leaseback Area for purposes
            other than general office purposes Landlord shall first be required
            to obtain Tenant's consent to such alterations which consent, Tenant
            agrees, (i) shall not be unreasonably withheld or delayed and (ii)
            shall be deemed given in the event Tenant does not respond to a
            request therefor within thirty (30) days after such request is made;

                  (2) it shall provide that Tenant will at all times permit
            reasonably appropriate means of ingress to and egress from the
            Leaseback Area;

                  (3) such sublease shall expressly negate any intention that
            the estate created under such sublease be merged with any other
            estate held by either of the parties;

                  (4) the sublease shall not provide for any work to be done for
            the subtenant or for any initial rent concessions or contain
            provisions inapplicable to a sublease;

                  (5) it shall provide that at the expiration of the term of
            such sublease Tenant will accept the Leaseback Area in its then
            existing condition, subject to the obligation of Landlord to make
            such repairs thereto as may be necessary to preserve the Leaseback
            Area in good order and condition, ordinary wear and tear excepted in
            accordance with Tenant's obligations to repair the demised premises
            as set forth in Article 7 hereof provided, however, that in the
            event Landlord shall have altered the Leaseback Area so that the
            same is not suitable for general office purposes Landlord shall, at
            Landlord's expense, restore the Leaseback Area to general office
            space;


                                       31
<PAGE>

                  (6) it shall provide that any consent required of Tenant, as
            lessor under that sublease, shall be deemed granted if consent with
            respect thereto is granted by Landlord except the consent required
            under clause (1) above;

                  (7) there shall be no limitation as to the use of the sublet
            premises by the subtenant thereunder except (a) as set forth in
            Article 37 and Article 5 hereof, and (b) Landlord shall not permit
            use of the sublet premises by any of "Tenant's Competitors" (as that
            term is defined in Section 11.11 hereof);

                  (8) any failure of the subtenant thereunder to comply with the
            provisions of said sublease, other than with respect to the payment
            of rent to Tenant or the willful misconduct of such subtenant which
            causes damage to Tenant, shall not constitute a default thereunder
            if Landlord has consented to such noncompliance;

                  (9) Tenant shall be released from all obligations under this
            Lease as to the Leaseback Area during the period of time it is
            sublet to Landlord, other than from Tenant's obligations to pay
            fixed annual rent and additional rent therefor and any default under
            any such sublease shall not give rise to default under a similar
            obligation contained in this Lease, nor shall Tenant be liable for
            any default under this Lease or deemed to be in default hereinunder
            if such default is occasioned by or arises from any act or omission
            of the subtenant under such sublease or is occasioned by or arises
            from any act or omission of any occupant holding under or pursuant
            to any such sublease; and

                  (10) the rental terms shall be the rental terms contained in
            this Lease on a per rentable square foot basis.

      If pursuant to the exercise of any of Landlord's options pursuant to this
      Section 11.05 this Lease is terminated as to only a portion of the demised
      premises, then the fixed annual rent payable hereunder and the additional
      rent payable pursuant to Articles 3 and 4 hereof shall be adjusted in
      proportion to the portion of the demised premises affected by such
      termination.

      11.6. (a) If Landlord shall exercise any of its options under Section
11.05 hereof and shall thereafter enter into one or more leases or underleases
with respect to all or any portion of the demised premises as to which Landlord
shall have exercised such option, Landlord shall pay to Tenant after deduction
of "Permitted Expenses" (as such term is hereinafter defined) fifty percent
(50%) of any rents, additional charges or other consideration paid under such
lease or underlease or otherwise by the tenant or undertenant, as the case may
be, during the then balance of the term of this Lease which are in excess of the
fixed annual rent or additional rent (if such excess in fact exists) payable by
Tenant hereunder (or which would be payable by Tenant hereunder if the Lease
were in


                                       32
<PAGE>

effect) commencing upon the effective date of such option and for the balance of
the term of this Lease with respect to such space Con a proportionate rentable
area basis). Amounts received by Landlord or any Affiliate of Landlord for
performing any services for any tenant or undertenant shall not be considered
consideration received by Landlord for purposes of this Section 11.06. As used
herein the term "Permitted Expenses" shall mean the aggregate of (i) usual
broker commissions and reasonable legal fees incurred by Landlord in connection
with any such lease or underlease, (ii) the costs, if any, incurred by Landlord
in separating the space from the balance of the demised premises, (iii)
reasonable advertising expenses incurred by Landlord, (iv) reasonable costs
incurred by Landlord in preparing the space for occupancy, including cash
allowances in lieu thereof, and (v) the amount of any lost rent resulting from
rent concession or abatement periods not exceeding six months. "Permitted
Expenses" shall be reduced by the aggregate of expenses in the nature of those
listed in subdivisions (i) through (v) hereof incurred by Tenant in connection
with the procurement of such tenant or undertenant.

            (b) If Landlord shall exercise any of its options under Section
      11.05 hereof, then the number of parking spaces of which Tenant shall have
      free use pursuant to Section 17.03 hereof shall be reduced as provided in
      Section 17.03 hereof.

      11.7. In the event that Landlord does not exercise any of the options
available to it pursuant to Section 11.05 hereof, Landlord shall not
unreasonably withhold or delay its consent to an assignment of this Lease or a
subletting of the whole or a part of the demised premises provided:

            (a) Tenant shall furnish Landlord with the name and business address
      of the proposed subtenant or assignee, information with respect to the
      nature and character of the proposed subtenant's or assignee's business,
      or activities, an executed counterpart of the sublease or assignment
      agreement and with respect to a proposed subletting of 30,000 or more
      rentable square feet of the demised premises (any such subletting is
      herein called a "Material Sublease") such references and current financial
      information with respect to net worth, credit and financial responsibility
      as are reasonably satisfactory to Landlord;

            (b) The nature and character of the proposed subtenant or assignee,
      its business or activities and intended use of the demised premises, is
      not in violation of Articles 5 or 37 hereof;

            (c) The proposed subtenant or assignee is not then an occupant of
      any part of the Building or a party who dealt with Landlord or Landlord's
      agent (directly or through a broker) with respect to space in the Building
      during the three (3) months immediately preceding Tenant's request for
      Landlord's consent;

            (d) All costs incurred with respect to providing reasonably
      appropriate means of ingress and egress from the sublet space or to
      separate the sublet space from the remainder of the demised premises
      shall, subject to the provisions of


                                       33
<PAGE>

      Article 6 hereof with respect to alterations, installations, additions or
      improvements be borne by Tenant;

            (e) Each sublease or assignment shall specifically state that (i) it
      is subject to all of the terms, covenants, agreements, provisions, and
      conditions of this Lease, including the waiver, agreement and permission
      requirements set forth in Section 9.04 hereof as applied to the subtenant
      or assignee, (ii) the subtenant or assignee, as the case may be, will not
      have the right to a further assignment thereof or sublease or assignment
      thereunder, or to allow the demised premises to be used by others, without
      the consent of Landlord in each instance, provided, however, Landlord
      agrees that it will not unreasonably withhold its consent or approval with
      respect to an initial assignment or subletting by (l) the permitted
      assignee of the Lease or (2) subtenant of a Material Sublease of the named
      Tenant herein, (iii) a consent by Landlord thereto shall not be deemed or
      construed to modify, amend or affect the terms and provisions of this
      Lease, or Tenant's obligations hereunder, which shall continue to apply to
      the premises involved, and the occupants thereof, as if the sublease or
      assignment had not been made.

            (f) Tenant shall together with requesting Landlord's consent
      hereunder, have paid Landlord any costs incurred by Landlord to review the
      requested consent including any reasonable attorneys fees incurred by
      Landlord;

            (g) The proposed subtenant or assignee is not an entity set forth in
      Article 37 hereof;

            (h) In the case of a subletting of a portion of the demised
      premises, the portion so sublet shall be at least 2,500 rentable square
      feet and regular in shape and such subletting will not result in more than
      four occupants (including Tenant) occupying any floor of the demised
      premises.

            (i) Tenant shall not publicly advertise the demised premises at a
      rental rate less than the rental rates then being charged under leases
      being entered into by Landlord for comparable space in the Building and
      for a comparable term.

      11.8. In the event that (a) Landlord fails to exercise any of its options
under Section 11.05 hereof and Tenant fails to execute and deliver an assignment
or sublease within 180 days after the giving of Tenant's notice of its intention
with respect thereto, then, Tenant shall again comply with all of the provisions
and conditions of Section 11.05 before assigning this lease or subletting the
demised premises, provided however if Tenant shall within thirty (30) days after
the expiration of said 180 day period agree to assign the Lease or sublease the
demised premises and shall submit the same to Landlord as described in Section
11.05 hereof, Landlord shall have twenty (20) days to make the elections set
forth in Section 11.05 with respect to such assignment or sublease.

      11.9. (a) If Landlord shall fail to respond to Tenant's request for
Landlord's consent to a proposed subletting or assignment within thirty (30)
days after Tenant's


                                       34
<PAGE>

submission thereof, then provided Tenant shall have fully complied with the
provisions of this Article 11 with respect to such assignment or subletting,
Landlord shall be deemed to have consented thereto.

            (b) If the Landlord shall give or be deemed to have given its
      consent to any assignment of this Lease or to any sublease, Tenant shall
      in consideration therefor, pay to Landlord, as additional rent:

                  (i) in the case of an assignment, an amount equal to fifty
            (50%) percent of all sums and other considerations (hereinafter
            collectively called the "Assignment Consideration") paid to Tenant
            by the assignee for or by reason of such assignment or otherwise
            (including, but not limited to, sums paid for the sale of Tenant's
            fixtures, leasehold improvements, equipment, furniture, furnishings
            or other personal property, less, in the case of a sale of Tenant's
            personal property, the higher of: (A) the then net unamortized or
            undepreciated cost thereof determined on the basis of Tenant's
            federal income tax returns or (B) the then fair market value thereof
            but excluding from the Assignment Consideration all reimbursements
            by an assignee to Tenant for amounts actually expended by Tenant in
            providing services for such assignee); and

                  (ii) in the case of a sublease, an amount equal to fifty (50%)
            percent of any rents, additional charge or other consideration
            payable under the sublease or otherwise to Tenant by the subtenant
            which is in excess (hereinafter called the "Excess Amount") of the
            fixed annual rent and additional rent accruing during the term of
            the sublease in respect of the subleased space Cat the rate per
            square foot payable by Tenant hereunder) pursuant to the terms
            hereof (including, but not limited to, sums paid for the sale or
            rental of Tenant's fixtures, leasehold improvements, equipment,
            furniture or other personal property, less, in the case of the sale
            of Tenant's personal property, the higher of: (A) the then net
            unamortized or undepreciated cost thereof determined on the basis of
            Tenant's federal income tax returns or (B) the then fair market
            value thereof).

In determining the Excess Amount and the Assignment Consideration there shall be
deducted therefrom the amount of any Permitted Expenses. As used in the next
preceding sentence the term "Permitted Expenses" shall have the same meaning as
set forth in subsection 11.06(a) hereof except that for the purposes of this
Section 11.09, Permitted Expenses shall be expenses incurred by Tenant in
connection with any subletting or assignment pursuant to this Section 11.09.

The sums payable under this Section 11.09 shall be paid to Landlord as and when
paid by the subtenant or assignee, as the case may be, to Tenant.

Tenant shall advise Landlord in the event of a sale of personal property in
connection with an assignment or subletting of the value allocated thereto and,
upon Landlord's


                                       35
<PAGE>

request, the undepreciated cost thereof determined on the basis of Tenant's
federal income tax returns. In the event that such allocated value exceeds such
undepreciated cost, Landlord may, at its election, dispute such valuation within
thirty (30) days after the submission thereof, in which event Landlord shall
name an appraiser reasonably satisfactory to Tenant (or if the parties are
unable to agree, an appraiser selected at the initiative of either party by the
American Arbitration Association) to conclusively establish the fair market
value of such property.

      11.10. If Tenant defaults in the payment of any rent, Landlord is
authorized to collect any rents due or accruing from any assignee, subtenant or
other occupant of the demised premises and to apply the net amounts collected to
the fixed annual rent and additional rent reserved herein. The receipt by
Landlord of any amounts from an assignee or subtenant, or other occupant of any
part of the demised premises shall not be deemed or construed as releasing
Tenant from Tenant's obligations hereunder or the acceptance of that party as a
direct tenant.

      11.11. For the purposes of Subsection ll.05(c)C7) hereof, the term
"Tenant's Competitors" shall mean an entity whose principal business shall be
that of a health insurer, health care provider or health maintenance
organization (which may include a division or subsidiary of Landlord) but
nothing in this Section 11.11 shall prohibit Landlord from leasing any portion
of the Building to a tenant having a division or subsidiary engaged in such
business, provided such division or subsidiary shall not occupy such portion of
the Building. Notwithstanding any language to the contrary contained in this
Section 11.11, Tenant agrees that the existing tenants of The Building Project
and any affiliates or successors thereto shall not be deemed a Tenant's
Competitor.

      11.12. Notwithstanding any language to the contrary contained in Section
11.05(c) hereof, in the event that Tenant should agree subject to the provisions
of this Lease to sublet (such sublease is hereinafter called a "Partial Term
Sublease") a portion of the demised premises for a term which is less than
substantially all of the balance of the then term of this Lease, then provided
(i) Tenant shall have entered into three or more subleases of the space
(hereinafter called the "Partial Term Sublease Space") proposed to be sublet by
the Partial Term Sublease during the six (6) year period prior to the date
Tenant shall deliver such Partial Term Sublease to Landlord pursuant to
subsection 11.05(c) hereof, and (ii) the sum of (a) the rentable area demised
under the Partial Term Sublease Space, and (b) the rentable area of the demised
premises currently being subleased by Tenant shall be 50,000 rentable square
feet or more, Landlord shall have the right to terminate the Lease with respect
to such Partial Term Sublease Space as of the proposed effective date of such
Partial Term Sublease.

      11.13. At the request of Tenant, Landlord shall enter into an agreement
with any subtenant of Tenant which has been approved by Landlord pursuant to the
provisions of Section 11.07 hereof providing that, if Landlord shall succeed to
the interest of Tenant under Tenant's sublease agreement (hereinafter called an
"Approved Sublease") with such subtenant as a result of the default of Tenant
under this Lease, Landlord shall be


                                       36
<PAGE>

bound by the provisions of such Approved Sublease and shall not terminate such
Approved Sublease so long as the subtenant shall not be in default thereunder,
provided that: (a) the fixed rent and additional rent payable under the Approved
Sublease are not less than the fixed rent and additional rent payable under this
Lease from time to time on a pro rata basis; (b) the Approved Sublease covers
not less than 50,000 rentable square feet; (c) the subleased space does not
destroy the contiguity of the balance of the demised premises; and (d) the
subtenant is a reputable party whose financial net worth, credit and financial
responsibility is, considering the rental payable under the Approved Sublease,
reasonably satisfactory to Landlord.

      11.14. In the event that this Lease shall be assigned to Landlord or
Landlord's designee or if the demised premises shall be sublet to Landlord or
Landlord's designee pursuant to Section 11.05, the provisions of any such
sublease or assignment and the obligations of Landlord and the rights of Tenant
with respect thereto shall not be binding upon or otherwise affect the rights of
any holder of a superior mortgage or of a lessor under a superior lease unless
such holder or lessor shall elect by written notice to Tenant to succeed to the
position of Landlord or its designee, as the case may be, thereunder.

                                   ARTICLE 12

                                   ELECTRICITY

      12.1. (a)   Landlord shall furnish to Tenant the electric energy which
                  Tenant requires in the demised premises on a "rent inclusion"
                  basis, through the presently installed electrical facilities
                  for Tenant's reasonable use in the demised premises of the
                  heating, ventilating and air conditioning equipment in the
                  demised premises and for lighting, light office and mechanical
                  equipment that does not require in excess of a 110 volt line.
                  Subject to the following provisions of this Section 12.01,
                  there shall be no charge to Tenant therefor by way of
                  measuring the same on any meter or otherwise, electric current
                  being included as an additional service in the fixed annual
                  rent payable hereunder.

                  (b) Tenant acknowledges and agrees (i) that the fixed annual
            rent hereinabove set forth in this Lease includes an Electricity
            Rent Inclusion Factor (as hereinafter defined), of $247,108.50 to
            compensate Landlord for the electrical wiring and other
            installations necessary for, and for its obtaining and
            redistribution of, electric current as an additional service to the
            demised premises; and (ii) that said Electricity Rent Inclusion
            Factor (hereinafter called "ERIF") has been partially based upon
            Tenant's estimated connected electrical load and hours of use
            thereof for ordinary lighting, heating, ventilating, air
            conditioning and light office equipment, during ordinary business
            hours in the demised premises. If Tenant requires a greater or
            lesser amount of electric energy than estimated, including electric
            energy to be supplied to the demised premises for heating,
            ventilating, air conditioning, lighting and light office equipment
            and equipment other than


                                       37
<PAGE>

            ordinary lighting and office equipment, then the ERIF shall not be
            adjusted, but Tenant shall pay, as additional rent, or Landlord
            shall credit Tenant the "Adjustment" (as hereinafter defined). The
            "Adjustment" shall mean the amount remaining (whether a positive or
            negative number) after subtracting the ERIF from the amount
            determined by applying the connected electrical load and usage and
            demand (hereinafter called "Tenant's Actual Electrical Usage")
            thereof in the demised premises (as determined by the electrical
            consultant as hereinafter provided) to the rate charged for such
            load and usage in the service classification in effect on the date
            of this Lease pursuant to which Landlord then purchased electric
            current for the entire Building from the public utility corporation.
            If the cost to Landlord of electricity shall have been, or shall be,
            increased or decreased subsequent to the date of this Lease (whether
            such increase or decrease occurs prior to or during the term of this
            Lease), by change in Landlord's electric rates, charges, fuel
            adjustment, or service classifications, or by taxes or charges of
            any kind imposed thereon, or for any other such reason, then the
            same shall be taken into account in computing the Adjustment. The
            Adjustment shall be calculated monthly, in arrears, by Landlord's
            consultant as provided in paragraph (d) hereof.

                  (c) Any such increase or decrease in Landlord's cost due to
            change in Landlord's electric rates, charges, etc., shall be
            computed by the application of the average consumption (energy and
            demand) of electricity for the entire Building for the twelve (12)
            months immediately prior to the rate change, other change in cost,
            or any changed methods of or rules on billing for same, on a
            consistent basis to the new rate and/or service classifications and
            to the immediately prior existing rate and/or service
            classifications. The parties acknowledge that they understand that
            it is anticipated that existing electric rates, charges, etc. may be
            changed by virtue of time of day rates or other methods of billing,
            and that the foregoing reference to changes in methods of or rules
            on billing is intended to include any such change. The parties agree
            that a reputable, independent electrical consultant, selected by
            Landlord ("Landlord's electrical consultant") shall determine the
            Adjustment based on changes in Landlord's electric rates, charges,
            etc.

                  (d) Tenant's Actual Electrical Usage shall be calculated on a
            monthly basis by Landlord's electrical consultant using the check
            meters located in the demised premises and making such adjustments
            to the measurements thereof as may be deemed necessary by such
            consultant. If any meters or other equipment must be installed to
            check electric service to the demised premises, the same shall be
            installed by Landlord at Landlord's expense, not to exceed in the
            aggregate $20,000.00, and Tenant shall reimburse Landlord for the
            cost thereof in excess of $20,000.00 in such equal monthly amounts
            commencing after Landlord's completion of the installation thereof
            as shall amortize such cost over the number of full months then
            remaining in the term of this Lease without regard to any
            unexercised rights of renewal or extension hereunder, and such
            monthly amounts shall be paid by Tenant to Landlord as additional
            rent hereunder.


                                       38
<PAGE>

                  (e) The determination of Landlord's consultant shall be
            binding and conclusive on Landlord and on Tenant from and after the
            delivery of copies of such determination to Landlord and Tenant,
            unless within ninety (90) days after the delivery of such copies,
            Tenant disputes such determination. If Tenant disputes the
            determination, it shall, at its own expense, obtain from a
            reputable, independent electrical consultant its own survey of
            Tenant's Actual Electrical Usage in the demised premises in
            accordance with the provisions of this Article 12. Tenant's
            consultant and Landlord's consultant then shall seek to agree on a
            finding of such determination of Tenant's Actual Electrical Usage.
            If they cannot agree, they shall choose a third reputable electrical
            consultant whose cost shall be shared equally by Landlord and
            Tenant, to make a similar survey, and the determination of such
            third electrical consultant shall be controlling. (If they cannot
            agree on such third consultant, within ten (10) days, then either
            party may apply to the Superior Court Judicial District of Stamford!
            Norwalk at Norwalk Housing Session, State of Connecticut for the
            appointment of such third consultant.) However, pending such
            determination, Tenant shall pay to Landlord the amount of the ERIF
            and the Adjustment as determined by Landlord's electrical
            consultant, then Landlord and Tenant shall make adjustment for any
            deficiency owed by Tenant or overage paid by Tenant pursuant to the
            decision of Landlord's electrical consultant together with interest
            on such adjustment at the Interest Rate from the date owed, in the
            case of a deficiency, or from the date paid, in the case of an
            overage.

      12.2. Landlord reserves the right to discontinue furnishing electric
energy to Tenant at any time upon one hundred eighty (180) days' written notice
to Tenant provided Landlord shall have previously or contemporaneously therewith
discontinued furnishing electricity to at least seventy-five (75%) percent of
the rentable area in the Building (including the demised premises). From and
after the effective date of such termination, Landlord shall no longer be
obligated to furnish Tenant with electric energy, provided, however, that such
termination date shall be extended for a time reasonably necessary for Tenant to
make arrangements to obtain electric service directly from the public utility
company servicing the Building. If Landlord exercises such right of termination,
this Lease shall remain unaffected thereby and shall continue in full force and
effect; and thereafter Tenant shall diligently arrange to obtain electric
service directly from the public utility company servicing the Building, and may
utilize the then existing electric feeders, risers and wiring serving the
demised premises to the extent available and safely capable of being used for
such purpose and only to the extent of Tenant's then authorized connected load.
Landlord shall be obligated to pay the reasonable cost required for Tenant to
obtain direct electric service unless Landlord discontinued furnishing
electricity to Tenant by reason of Legal Requirements or the rules and
regulations of the public utility furnishing electricity to the Building, in
which case Landlord and Tenant shall share equally such costs. Commencing with
the date when Tenant receives such direct service, and as long as Tenant shall
continue to receive such service, the ERIF amount and Adjustments shall not be
payable and Tenant shall obtain electric service direct from the utility
furnishing such power to the Building and shall pay all charges therefor to such
utility.


                                       39
<PAGE>

      12.3. Tenant agrees not to connect any additional electrical equipment of
any type to the Building electric distribution system, other than lamps,
typewriters and other small office machines which consume comparable amounts of
electricity, without Landlord's prior written consent, which consent shall not
be unreasonably withheld. To facilitate Tenant's increasing automation of its
operations, any additional risers, feeders, or other equipment proper or
necessary to supply Tenant's electrical requirements may be installed by Tenant,
at the sole cost and expense of Tenant and in accordance with the provisions of
Article 6 hereof, if, the same are necessary and will not cause permanent damage
or injury to the Building or the demised premises, or cause or create a
dangerous or hazardous condition or entail excessive or unreasonable
alterations, repair or expense or unreasonably interfere with or disturb other
tenants or occupants and provided same does not adversely affect Landlord's
reasonable estimates of the electrical capacity required for the needs of
existing and future tenants of the Building and for the proper maintenance and
operation of the Building. In applying the provisions of Article 6 to any work
permitted hereunder, any consent required under Article 6 to be obtained from
Landlord shall not be unreasonably withheld or delayed. Landlord shall not in
anywise be liable or responsible to Tenant for any loss or damage or expense
which Tenant may sustain or incur if either the quantity or character of
electric service is changed or is no longer available or suitable for Tenant's
requirements. Nothing contained in the preceding sentence shall be deemed to
exculpate Landlord its agents, servants or designees from liability for its
negligent or wilfull acts.

                                   ARTICLE 13

                          DAMAGE BY FIRE OR OTHER CAUSE

      13.1. If the Building or the demised premises shall be partially or
totally damaged or destroyed by fire or other cause, then whether or not the
damage or destruction shall have resulted from the fault or neglect of Tenant,
or its employees, agents or visitors (and if this Lease shall not have been
terminated as in this Article 13 hereinafter provided), Landlord shall repair
the damage and restore and rebuild the Building and/or the demised premises, at
its expense (without limiting the rights of Landlord under any other provisions
of this Lease), with reasonable dispatch after notice to it of the damage or
destruction; provided, however, that Landlord shall not be required to repair or
replace any of Tenant's property.

      13.2. If the Building or the demised premises shall be partially damaged
or partially destroyed by fire or other cause, the fixed annual rent and
additional rent payable hereunder shall be abated to the extent that the demised
premises shall have been rendered untenantable for the period from the date of
such damage or destruction to the date the damage shall be repaired or restored.
If fifty (50%) percent or more of the area of the demised premises shall be
totally (which shall be deemed to include substantially totally) damaged or
destroyed or rendered completely (which shall be deemed to include substantially
completely) untenantable on account of fire or other cause, the fixed annual


                                       40
<PAGE>

rent and additional rent shall abate as of the date of the damage or destruction
and until Landlord shall repair, restore and rebuild the Building and the
demised premises, provided, however, that should Tenant reoccupy a portion of
the demised premises during the period the restoration work is taking place and
prior to the date that the same are made completely tenantable, rents allocable
to such portion shall be payable by Tenant from the date of such occupancy.

      13.3. (a)   If the Building shall be totally damaged or destroyed by fire
                  or other cause, or if the Building shall be so damaged or
                  destroyed by fire or other cause (whether or not the demised
                  premises are damaged or destroyed) as to require a reasonably
                  estimated expenditure of more than forty (40%) percent of the
                  full insurable value of the Building immediately prior to the
                  casualty, then, in either such case, Landlord may terminate
                  this Lease by giving Tenant notice to such effect within sixty
                  (60) days after the date of the casualty. In case of any
                  damage or destruction mentioned in this Article 13 and
                  Landlord shall decide to restore the Building, Landlord shall
                  give Tenant a notice of Landlord's estimate of the reasonable
                  expected date of restoration (as evidenced by a certificate of
                  Landlord's architect) within sixty (60) days after the date of
                  the casualty. If such estimated restoration date shall be
                  later than 18 months after the date of such damage or
                  destruction, then Tenant may terminate this Lease by giving
                  Landlord notice to such effect within ten (10) days after the
                  date of Landlord's notice. Thereafter, Tenant may terminate
                  this Lease upon ten (10) days notice to Landlord, if Landlord
                  has not substantially completed the making of the required
                  repairs and restored and rebuilt the Building within
                  Landlord's estimated restoration period or within such period
                  thereafter (not to exceed one (l) month) as shall equal the
                  aggregate period Landlord may have been delayed in doing so by
                  adjustment of insurance, labor trouble, governmental controls,
                  act of god, or any other cause beyond Landlord's reasonable
                  control.

            (b) If any damage or destruction described in this Section 13.03
      shall occur at any time during the last two (2) years of the term of this
      Lease, Tenant may terminate this Lease by notice given to Landlord within
      twenty (20) days after the date of such casualty, if the demised premises
      cannot reasonably (as evidenced by a certificate from Landlord's
      architect) be restored within three (3) months from the date of such
      damage or destruction or if Landlord has not substantially completed the
      making of the required repairs and restored and rebuilt the Building and
      the demised premises within three (3) months from the date of such damage
      or destruction.

            (c) In the event of any damage by fire or other casualty to the
      Building or the demised premises which results in a termination of this
      Lease by Landlord, Tenant shall be permitted to remain in occupancy after
      the casualty of any portion


                                       41
<PAGE>

      of the demised premises which shall not have been rendered untenantable by
      such casualty for a period following the casualty not to exceed six (6)
      months upon all the terms and conditions of this Lease, provided such
      continued occupancy shall not (i) be prohibited by Legal Requirements,
      (ii) in Landlord's reasonable judgment be hazardous or create a hazardous
      condition, (iii) interfere with Landlord's restoration of the Building or
      the demised premises, or (iv) prevent Landlord from demolishing the
      Building or any portion thereof pursuant to a Legal Requirement, and if
      Tenant shall so continue in occupancy, Tenant shall remain responsible for
      a pro rata portion of the fixed annual rent and additional rent payable by
      Tenant hereunder, based upon the portion of the demised premises occupied
      by Tenant during such period.

            (d) In the event Landlord shall restore the demised premises or the
      Building as described in this Section 13.03, Tenant's obligations to pay
      fixed annual rent and additional rent hereunder shall resume upon the
      earlier to occur of (i) the date Tenant shall occupy the demised premises
      for the conduct of its business or (ii) the later of (x) the date provided
      by Landlord in its notice as the expected date of restoration or (y) such
      date as the repair and restoration of the demised premises shall have been
      substantially completed.

            (e) The repair and restoration provided in this Section 13.03 shall
      be deemed substantially complete (i) notwithstanding the fact that minor
      or insubstantial details of construction, mechanical adjustment, or
      decoration remain to be performed, the non completion of which do not
      materially interfere with Tenant's use of the demised premises and (ii) if
      such repair and restoration has been substantially completed except for
      portions thereof which under good construction scheduling practice should
      be done after still incompleted Tenant's finish work.

            (f) If the occurrence of the conditions set forth in subsection (e)
      hereof and thereby the substantial completion of the repair and
      restoration shall be delayed due to any act or omission of Tenant or any
      of its employees, agents or contractors or any failure to plan or to
      execute Tenant's finish work diligently and expeditiously, the repair and
      restoration shall be deemed substantially complete on the date when they
      would have been substantially complete but for such delay.

      13.4. No damages, compensation or claim shall be payable by Landlord for
inconvenience, loss of business or annoyance arising from any repair or
restoration of any portion of the demised premises or of the Building pursuant
to this Article 13.

      13.5. Notwithstanding any of the foregoing provisions of this Article 13,
if Landlord or the lessor of any superior lease or the holder of any superior
mortgage shall be unable to collect all of the insurance proceeds (including
rent insurance proceeds) applicable to damage or destruction of the demised
premises or the Building by fire or other cause, by reason of Tenant's failure
or refusal to cooperate with Landlord in making a claim for such proceeds, then,
without prejudice to any other remedies which may be


                                       42
<PAGE>

available against Tenant, there shall be no abatement of Tenant's rents, but the
total amount of such rents not abated (which would otherwise have been abated)
shall not exceed the amount of uncollected insurance proceeds.

      13.6. Landlord will not carry separate insurance of any kind on Tenant's
property, and, except as provided by law or by reason of its breach of any of
its obligations hereunder, shall not be obligated to repair any damage thereto
or replace the same. Tenant shall maintain insurance on Tenant's property, and
Landlord shall not be obligated to repair any damage thereto or replace the
same.

      13.7. The provisions of this Article 13 shall be considered an express
agreement governing any cause of damage or destruction of the demised premises
by fire or other casualty, and, to the extent permitted under applicable law, no
statute, rule, law or regulation of the State of Connecticut or any of its
political subdivisions now or hereafter in force and providing for such a
contingency in the absence of an express agreement, shall have application in
such case.

                                   ARTICLE 14

                                  CONDEMNATION

      14.1. In the event that the whole of the demised premises shall be
lawfully condemned or taken in any manner for any public or quasi public use,
this Lease and the term and estate hereby granted shall forthwith cease and
terminate as of the date of vesting of title. In the event that only a part of
the demised premises shall be so condemned or taken, then, effective as of the
date of vesting of title, the fixed annual rent under Article 1 hereunder and
additional rents under Articles 3 and 4 hereunder shall be abated in an amount
thereof apportioned according to the area of the demised premises so condemned
or taken. In the event that only a part of The Building Project (as such term is
defined in subsection 3.02(b) hereof) shall be so condemned or taken, then (a)
Landlord (whether or not the demised premises be affected) may, at Landlord's
option, terminate this Lease and the term and estate hereby granted as of the
date of such vesting of title by notifying Tenant in writing of such termination
within 60 days following the date on which Landlord shall have received notice
of vesting of title, or (b) if such condemnation or taking shall be of a
substantial part (i.e., forty (40%) or more of (i) the rentable area of the
demised premises or (ii) the aggregate number of parking spaces available for
Tenant's use, provided Landlord shall be permitted to make substitutions
thereof) of the demised premises or of a substantial part of the means of access
thereto, Tenant may, at Tenant's option, by delivery of notice in writing to
Landlord within 60 days following the date on which Tenant shall have received
notice of vesting of title, terminate this Lease and the term and estate hereby
granted as of the date of vesting of title, or (c) if neither Landlord nor
Tenant elects to terminate this Lease, as aforesaid, this Lease shall be and
remain unaffected by such condemnation or taking, except that the fixed annual
rent payable under Article 1 and additional rents payable under Articles 3 and 4
shall be abated to the extent hereinbefore provided in this Section 14.01.


                                       43
<PAGE>

      14.2. In the event of its termination in any of the cases hereinbefore
provided, this Lease and the term and estate hereby granted shall expire as of
the date of such termination with the same effect as if that were the Expiration
Date, and the fixed annual rent and additional rents payable hereunder shall be
apportioned as of such date.

      14.3. In the event of any condemnation or taking hereinbefore mentioned of
all or a part of the Building, Landlord shall be entitled to receive the entire
award in the condemnation proceeding, including any award made for the value of
the estate vested by this Lease in Tenant, and Tenant hereby expressly assigns
to Landlord any and all right, title and interest of Tenant now or hereafter
arising in or to any such award or any part thereof, and Tenant shall be
entitled to receive no part of such award, except Tenant shall be entitled to
make a separate claim with the condemning authority for the value of any
Tenant's property so taken and for Tenant's moving expenses.

      14.4. It is expressly understood and agreed that the provisions of this
Article 14 shall not be applicable to any condemnation or taking for
governmental occupancy for a limited period.

      14.5. In the event of any taking of less than the whole of the Building or
the demised premises which does not result in a termination of this Lease, or in
the event of a taking for a temporary use or occupancy of all or any part of the
demised premises which does not result in a termination of this Lease, Landlord,
at its expense, and whether or not any award or awards shall be sufficient for
the purpose, shall proceed with reasonable diligence to repair, alter and
restore the remaining parts of the Building and the demised premises to
substantially their former condition to the extent that the same may be feasible
and so as to constitute a complete and tenantable Building and demised premises.

      14.6. In the event any part of the demised premises be taken to effect
compliance with any law or requirement of public authority other than in the
manner hereinabove provided in this Article 14, then, (i) if such compliance is
the obligation of Tenant under this Lease, Tenant shall not be entitled to any
diminution or abatement of rent or other compensation from Landlord therefor,
but (ii) if such compliance is the obligation of Landlord under this Lease, the
fixed annual rent hereunder shall be reduced and additional rents under Articles
3 and 4 shall be adjusted in the same manner as is provided in Section 14.01
according to the reduction in rentable area of the demised premises resulting
from such taking.

                                   ARTICLE 15

                       ACCESS TO DEMISED PREMISES; CHANGES

      15.1. Tenant shall permit Landlord to erect, use and maintain pipes, ducts
and conduits in and through the demised premises, provided the same are
installed adjacent to or concealed behind walls and ceilings of the demised
premises. Landlord shall to the


                                       44
<PAGE>

extent practicable install such pipes, ducts and conduits by such methods and at
such locations as will not materially interfere with or impair Tenant's layout
or use of the demised premises. Landlord or its agents or designees shall have
the right to enter the demised premises, at reasonable times during business
hours and except in case of emergency, upon reasonable notice (which need not be
in writing), for the making of such repairs or alterations as Landlord may deem
necessary for the Building or which Landlord shall be required to or shall have
the right to make by the provisions of this Lease or any other lease in the
Building and, subject to the foregoing, shall also have the right to enter the
demised premises for the purpose of inspecting them or exhibiting them to
prospective purchasers or lessees of the entire Building or to prospective
mortgagees of the fee or of the Landlord's interest in the property of which the
demised premises are a part or to prospective assignees of any such mortgages or
to the holder of any mortgage on the Landlord's interest in the property, its
agents or designees. Landlord shall be allowed to take all material into and
upon the demised premises that may be required for the repairs or alterations
above mentioned as the same is required for such purpose, without the same
constituting an eviction of Tenant in whole or in part, and the rent reserved
shall in no wise abate while said repairs or alterations are being made by
reason of loss or interruption of the business of Tenant because of the
prosecution of any such work. Nothing contained in this Section 15.01 shall
exculpate Landlord for the negligence of Landlord, its agents, servants or
others for whom as a matter of law it is liable. 'The reservation contained in
the preceding sentence shall, however, be subject to the provisions of Section
9.04 hereof. Landlord shall exercise reasonable diligence (including
consultation with Tenant) so as to minimize the disturbance but nothing
contained herein shall be deemed to require Landlord to perform the same on an
overtime or premium pay basis. The provisions of Section 7.06 hereof shall apply
to any entry by Landlord hereunder.

      15.2. Landlord reserves the right, without the same constituting an
eviction and without incurring liability to Tenant therefor, to change the
arrangement and/or location of public entrances, passageways, doors, doorways,
corridors, elevators, stairways, toilets and other public parts of the Building;
provided, however, that access to the Building shall not be cut off and that
there shall be no unreasonable obstruction of access to the demised premises or
unreasonable interference with the use or enjoyment thereof.

      15.3. Landlord may, during the twelve (12) months prior to expiration of
the term of this Lease, exhibit the demised premises to prospective tenants.

      15.4. If Tenant shall not be personally present to open and permit an
entry into the demised premises at any time when for any reason an entry therein
shall be urgently necessary by reason of fire or other emergency, Landlord or
Landlord's agents may forcibly enter the same without rendering Landlord or such
agents liable therefor (if during such entry Landlord or Landlord's agents shall
accord reasonable care to Tenant's property including, except in the case of
emergency, the use of any keys to the demised premises that shall have
previously been furnished to Landlord) and without in any manner affecting the
obligations and covenants of this Lease.

                                     DEFAULT

      16.1. If Tenant shall make an assignment of the property of Tenant for the
benefit of creditors, or shall file a voluntary petition under any bankruptcy or
insolvency law or any involuntary petition alleging an act of bankruptcy or
insolvency shall be filed against Tenant under any bankruptcy or insolvency law,
or whenever a petition shall be filed by or against Tenant under the
reorganization provisions of the United States Bankruptcy Act or under the
provisions of any law of like import, or whenever a petition shall be filed by
Tenant under the arrangement provisions of the United States Bankruptcy Act or
under the provisions of any law of like import, or whenever a permanent receiver
of Tenant or for the property of Tenant shall be appointed, then, Landlord may,
(a) at any time after receipt of notice of the occurrence of any such event, or
(b) if such event occurs without the acquiescence of Tenant, at any time after
the event continues for ninety (90) days, give Tenant a notice of intention to
end the term of this Lease at the expiration of five (5) days from the date of
service of such notice of intention, and upon the expiration of said five (5)
day period this Lease and the term and estate hereby granted, whether or not the
term shall theretofore have commenced, shall terminate with the same effect as
if that day were the Expiration Date, but Tenant shall remain liable for damages
provided in Section 16.03 hereof.

      16.2. If:

            (a) Tenant shall default in the payment of any installment of fixed
      annual rent, or in the payment of any additional rent or any other charge
      payable by Tenant to Landlord, on any day upon which the same ought to be
      paid, and such default shall continue for fifteen (15) days after Landlord
      shall have given Tenant a notice specifying such default; or

            (b) Tenant shall do or permit anything to be done, whether by action
      or inaction, contrary to any of Tenant's obligations hereunder, and if
      such situation shall continue and shall not be remedied by Tenant within
      twenty (20) days after Landlord shall have given to Tenant a notice
      specifying the same, or, in the case of a happening or default which
      cannot with due diligence be cured within a period of twenty (20) days and
      the continuance of which for the period required for cure will not subject
      Landlord to the risk of criminal liability as more particularly described
      in Article 8 hereof) or termination of any superior lease or foreclosure
      of any superior mortgage, if Tenant shall not, (i) within said twenty (20)
      day period advise Landlord of Tenant's intention to duly institute all
      steps necessary to remedy such situation, (ii) duly institute within said
      twenty (20) day period, and thereafter diligently prosecute to completion
      all steps necessary to remedy the same and (iii) complete such remedy
      within such time after the date of the giving of said notice of Landlord
      as shall reasonably be necessary; or


                                       46
<PAGE>

            (c) any event shall occur or any contingency shall arise whereby
      this Lease or the estate hereby granted or the unexpired balance of the
      term hereof would, by operation of law or otherwise, devolve upon or pass
      to any person, firm or corporation other than Tenant, except as expressly
      permitted by Article 11 hereof; or

            (d) Tenant shall abandon the demised premises (unless as a result of
      a casualty); or

            (e) in case any other lease held by Tenant from Landlord in the
      Building shall expire and terminate (whether or not the term thereof shall
      then have commenced) as a result of the default of Tenant thereunder or of
      the occurrence of an event as therein provided (other than by expiration
      of the fixed term thereof or pursuant to a cancellation or termination
      option therein contained); or

            (f) Tenant shall default in the due keeping, observing or
      performance of any covenant, agreement, provision or condition of Article
      5 hereof on the part of Tenant to be kept, observed or performed and if
      such default shall continue and shall not be remedied by Tenant within
      four (4) days after Landlord shall have given to Tenant a notice
      specifying the same, then in any of said cases set forth in the foregoing
      subsections 16.02 (a), (b), (c), (d), (e) and (f) hereof Landlord may (in
      addition to any and all rights at law or in equity) re enter and remove
      all persons and property from the demised premises and such property may
      be removed and stored in a public warehouse or elsewhere at the cost of,
      and for the account of Tenant, all without service of notice or resort to
      legal process and without being deemed guilty of trespass, or becoming
      liable for any loss or damage which may be occasioned thereby.

      16.3. Should Landlord elect to re enter, as herein provided, or should it
take possession pursuant to legal proceedings or pursuant to any notice provided
for by law, Landlord may either terminate this Lease, make such alterations and
repairs as may be necessary in order to relet the demised premises, and relet
the demised premises or any part thereof for such term or terms (which may be
for a term extending beyond the term of this Lease) and at such rental or
rentals and upon such other terms and conditions as Landlord in its discretion
may deem advisable; upon each such reletting all rentals received by Landlord
from such reletting shall be applied first, to the payment of any indebtedness
other than rent due hereunder from Tenant to Landlord; second, to the payment of
any costs and expenses of such reletting, including brokerage fees and
attorneys' fees and of costs of such alterations and repairs; third, to the
payment of rent due and unpaid hereunder, and the residue, if any, shall be held
by Landlord and applied in payment of future rent as the same may become due and
payable hereunder and if such residue shall exceed such future rental, Landlord
may retain such excess for its own account and Tenant shall have no interest
therein. If such rentals received from such reletting during any month be less
than that to be paid during that month by Tenant hereunder, Tenant shall pay any
deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No
such re entry or taking possession of the demised


                                       47
<PAGE>

premises by Landlord shall be construed as an election on its part to terminate
this Lease unless a written notice of such intention be given to Tenant or
unless the termination thereof be decreed by a court of competent jurisdiction.
Notwithstanding any such reletting without termination, Landlord may at any time
thereafter elect to terminate this Lease for such previous breach. Should
Landlord at any time terminate this Lease for any breach, in addition to any
other remedies it may have, it may recover from Tenant all damages it may incur,
by reason of such breach, including the cost of recovering the demised premises,
reasonable attorneys' fees, and including the worth at the time of such
termination of the excess, if any, of the amount of rent and charges equivalent
to rent reserved in this Lease for the remainder of the stated term over the
then reasonable rental value of the demised premises for the remainder of the
stated term, all of which amounts shall be immediately due and payable from
Tenant to Landlord. In determining the rent which would be payable by Tenant
hereunder, subsequent to default, the annual rent for each year of the unexpired
term shall be equal to the average fixed annual rent and additional rent paid by
Tenant from the Commencement Date to the time of default.

      16.4. In case Landlord shall retain an attorney to enforce the provisions
of this Lease or if suit shall be brought for recovery of possession of the
demised premises, for the recovery of rent or any other amount due under the
provisions of this Lease, or because of the breach of any other covenant herein
contained on the part of Tenant to be kept or performed, Tenant shall pay to
Landlord all expenses incurred by Landlord in connection therewith, including a
reasonable attorneys' fee.

      16.5. (a)   In the event of a breach or threatened breach by Tenant of
                  any of its obligations under this Lease, Landlord shall also
                  have the right of injunction. The special remedies to which
                  Landlord may resort hereunder are cumulative and are not
                  intended to be exclusive of any other remedies or means of
                  redress to which Landlord may lawfully be entitled at any
                  time, and, except as provided in Article 30 hereof, Landlord
                  may invoke any remedy allowed at law or in equity as if
                  specific remedies were not provided for herein.

            (b) In the event of a breach or threatened breach by Landlord of any
      of its obligations under this Lease, Tenant shall also have the right of
      injunction. Any remedies to which Tenant may resort hereunder are
      cumulative and are not intended to be exclusive of any other remedies or
      means of redress to which Tenant may lawfully be entitled at any time,
      and, except as provided in Article 30 hereof, Tenant may invoke any remedy
      allowed at law or in equity as if specific remedies were not provided for
      herein.

      16.6. If this Lease shall terminate under the provisions of this Article
16, or if Landlord shall re enter the demised premises under the provisions of
this Article 16, or in the event of the termination of this Lease, or of re
entry, by or under any summary process or other proceeding or action or any
provision of law by reason of default hereunder on the part of Tenant, Landlord
shall be entitled to retain all moneys, if any, paid by Tenant to Landlord,
whether as advance rent, security or otherwise, but such


                                       48
<PAGE>

moneys shall be credited by Landlord against any fixed annual rent or additional
rent due from Tenant at the time of such termination or re entry or, at
Landlord's option, against any damages payable by Tenant under this Article 16
or pursuant to law.

                                   ARTICLE 17

                            COMMON AREAS AND PARKING

      17.1. Landlord shall provide and shall make available from time to time
within the boundaries of the Land such parking facilities, driveways, entrances
and exits thereto, landscape and planted areas, and other improvements and
facilities, as Landlord shall at any time and from time to time deem appropriate
(all the foregoing being collectively referred to in this Lease as "Common
Areas"). Tenant and its officers, employees, agents, customers and invitees
shall have a nonexclusive right, in common with Landlord and all others to whom
Landlord has granted or may hereafter grant rights, to use the Common Areas. The
Common Areas shall at all times be subject to the exclusive control and
management of Landlord, and Landlord shall have the right from time to time to
establish, modify and enforce reasonable rules and regulations with respect to
the Common Areas, and Tenant agrees, after notice thereof, to abide by such
rules and regulations and to cause its officers, employees, agents, customers
and invitees to conform thereto. Landlord shall construct, operate, manage,
equip, repair, landscape, and maintain the Common Areas for their intended
purposes in such manner as Landlord shall, in Landlord's sole discretion, from
time to time determine. Landlord's rights respecting the Common Areas shall
include (but shall not be limited to) the following:

                  (i) to construct, maintain and operate lighting facilities
            serving the Common Areas;

                  (ii) from time to time to change the area, level, location and
            arrangement of parking areas and other Common Area facilities, to
            make installations therein and to move or remove such installations,
            and to change the location of, or permanently diminish or
            discontinue the use of, any portion of the Common Areas;

                  (iii) to restrict parking by tenants, their officers, agents,
            employees, customers and invitees, to designated areas;

                  (iv) to discontinue, or restrict the use of, any portion of
            the Common Areas to such extent, and for such period of time, as may
            in the opinion of Landlord's counsel be necessary to prevent a
            dedication thereof or the accrual of any rights to any person or the
            public therein;

                  (v) to temporarily suspend the use of all, or any portion of,
            the Common Areas; and


                                       49
<PAGE>

                  (vi) to take any other action with respect to the Common
            Areas, as Landlord, in his sole discretion, shall determine to be
            advisable.

      17.2. Tenant's right to use the Common Areas shall be deemed to be a
license conterminous with this Lease, and Landlord shall not be subject to any
liability nor shall Tenant be entitled to any compensation or diminution or
abatement of rent by reason of Landlord's exercise of any right or rights
respecting Common Areas reserved pursuant to Section 17.01 hereof, nor shall the
exercise of any such right be deemed a constructive or actual eviction.

      17.3. Tenant shall be entitled to free use of(591 parking spaces during
the term of this Lease provided that of such parking spaces shall be located
within the covered parking garage within the Common Areas. Notwithstanding the
foregoing, in the event Tenant shall give a notice to Landlord that Tenant
requires the free use of additional parking spaces, not to exceed 48 parking
spaces, Landlord shall make such spaces available within a reasonable period;
such additional parking spaces may be located within or outside of the Common
Areas. In the event that any of the foregoing parking spaces shall be designated
by Landlord, Tenant agrees that it or its employees and invitees shall only use
such designated parking spaces. Nothing contained in Section 17.01 hereof shall
be deemed to permit Landlord to reduce, except on a temporary basis, the number
of parking spaces to be made available to Tenant pursuant to this Section 17.03.
If at any time during the term of this Lease the rentable area of the demised
premises shall be reduced, the number of spaces allocated to Tenant pursuant to
this Section 17.03 shall be reduced in proportion to such reduction in rentable
area. Such reduction shall be made as follows: (A) to the extent that the number
of Tenant's parking spaces exceed the product of (i) the quotient of (x) the
rentable area of the demised premises (as reduced) divided by (y) 1,000,
multiplied by (ii) 3, such reduction shall begin with the parking spaces that
are located inside the Common Areas (but only to the extent required so that the
number of Tenant's parking spaces inside the Common Areas shall equal such
product); (B) any further reductions shall be made to Tenant's parking spaces
which are located outside the Common Areas (until, if necessary, all of Tenant's
parking spaces outside of the Common Areas shall have been eliminated); and (C)

                  shall not be joined as a party defendant to any foreclosure or
                  other action or proceeding (unless otherwise required by law)

                  of such mortgage, or their successors or

            assigns, (ii) Tenant's leasehold estate hereunder and possession of
            the demised premises shall not be terminated or disturbed nor shall
            any of Tenant's rights under this Lease be affected in any way by

            subject to the provisions of this Article 25, such lessor or the
            holder of such mortgage and their successors or assigns shall
            recognize the terms and provisions of this Lease, and Tenant's

thereof from rent due hereunder until Tenant shall have given written notice of
such act or omission to the ground lessor and to the holder of any mortgage on
the fee or the ground lease who shall have furnished such lessor's or holder's
last address to Tenant, and until a reasonable period for remedying such act or

time such lessor or holder shall have the right, but shall not be obligated, to

is further mutually agreed that in the event Landlord commences any summary

<PAGE>

      27.1. Upon the expiration or other termination of the term of this Lease,
(i) Tenant shall quit and surrender to Landlord the demised premises, broom
clean, in good order and condition, ordinary wear and tear (the provisions of
Section 7.01 hereof notwithstanding, i.e., to the extent that the demised
premises show signs of ordinary wear and tear upon such expiration or
termination, Tenant is not expected to restore or improve the same to eliminate
such signs) and damage by fire, the elements or other casualty excepted, and
shall remove all of its property as herein provided and (ii) with respect to
estimated payments or overpayments as to which Tenant may, pursuant to Article 3
hereof, be entitled to a refund, Landlord shall, within periods consistent with

                              RULES AND REGULATIONS

      28.1. Tenant and Tenant's servants, employees and agents shall observe
faithfully and comply strictly with the Rules and Regulations set forth in
Exhibit D attached hereto and made part hereof entitled "Rules and Regulations"
and such other and further reasonable Rules and Regulations as Landlord or
Landlord's agents may from time to time adopt provided, however, that in case of
any conflict or inconsistency between the provisions of this Lease and of any of
the Rules and Regulations as originally or as hereafter adopted, the provisions
of this Lease shall control. Reasonable written notice of any additional Rules
and Regulations shall be given to Tenant.

Nothing in this Lease contained shall be construed to impose upon Landlord any
duty or obligation to enforce the Rules and Regulations or the terms, covenants
or conditions in any other lease, against any other tenant of the Building, and
Landlord shall not be liable to Tenant for violation of the same by any other
tenant, its servants, employees, agents, visitors or licensees. Landlord shall

Regulations are applied against Tenant in an unreasonably discriminatory manner.

                             CONSENTS AND APPROVALS

      29.1. (a)   Wherever in this Lease Landlord's consent or approval is
                  required, if Landlord shall delay or refuse such consent or
                  approval, Tenant in no event shall be entitled to make, nor
                  shall Tenant make, any claim, and Tenant hereby waives any
                  claim, for money damages (nor shall Tenant claim any money
                  damages by way of set-off, counterclaim or defense) based upon
                  any claim or assertion by

<PAGE>

                  Tenant that Landlord unreasonably withheld or unreasonably
                  delayed its consent or approval. Tenant's sole remedy shall be
                  an action or proceeding to enforce any such provision, for
                  specific performance, injunction or declaratory judgment
                  provided, however, that Tenant shall not be deemed to have
                  waived a claim for damages if there is a final judicial
                  determination from which time for appeal has been exhausted
                  that Landlord acted maliciously or in bad faith in exercising
                  its judgement or withholding its consent or approval despite
                  its agreement to act reasonably, in which case Tenant shall
                  have the right to make a claim for the actual money damages
                  incurred by Tenant, but in no event shall Landlord be liable
                  for consequential or indirect damages.

            (b) Wherever in this Lease Tenant's consent or approval is required,
      if Tenant shall delay or refuse such consent or approval, Landlord in no
      event shall be entitled to make, nor shall Landlord make, any claim, and
      Landlord hereby waives any claim, for money damages (nor shall Landlord
      claim any money damages by way of set-off, counterclaim or defense) based
      upon any claim or assertion by Landlord that Tenant unreasonably withheld
      or unreasonably delayed its consent or approval. Landlord's sole remedy
      shall be an action or proceeding to enforce any such provision, for
      specific performance, injunction or declaratory judgment provided,
      however, that Landlord shall not be deemed to have waived a claim for
      damages if Tenant shall, in denying the consent, be found by a court of
      final jurisdiction to have acted in bad faith or with malice but in no
      event shall Tenant be liable for consequential or indirect damages.

                                     NOTICES

      30.1. Any notice or demand, consent, approval or disapproval, or statement
required to be given by the terms and provisions of this Lease, or by any law or
governmental regulation, either by Landlord to Tenant or by Tenant to Landlord,
shall be in writing. Unless otherwise required by such law or regulation, such
notice or demand shall be given, and shall be deemed to have been served and
given (x) two (2) Business Days after such notice or demand is mailed by
registered or certified mail deposited enclosed in a securely closed post paid
wrapper, in a United States Government general or branch post office, or
official depository with the exclusive care and custody thereof, (y) one
Business Day after such notice or demand is sent by a nationally recognized

Connecticut 06904 2305, Attention: Brian R. Smith, Esq. Either party may, by
notice as aforesaid, designate a different address or addresses for notices,
demands, consents, approvals or disapprovals.

      30.2. In addition to the foregoing, either Landlord or Tenant may, from
time to time, request in writing that the other party serve a copy of any notice
or demand, consent, approval or disapproval, or statement, on one other person
or entity designated in such request, such service to be effected as provided in
Section 31.01 hereof.

                                    NO WAIVER

      31.1. No agreement to accept a surrender of this Lease shall be valid
unless in writing signed by Landlord. No employee of Landlord or of Landlord's
agents shall have any power to accept the keys of the demised premises prior to
the termination of this Lease. The delivery of keys to any employee of Landlord
or of Landlord's agent shall not operate as a termination of this Lease or a
surrender of the demised premises. In the event of Tenant at any time desiring
to have Landlord sublet the premises for Tenant's account, Landlord or
Landlord's agents are authorized to receive said keys for such purpose without
releasing Tenant from any of the obligations under this Lease. The failure of
Landlord to seek redress for violation of, or to insist upon the strict
performance of, any covenant or condition of this Lease or any of the Rules and
Regulations set forth herein, or hereafter adopted by Landlord, shall not
prevent a subsequent act, which would have originally constituted a violation,
from having all the force and effect of an original violation. The receipt by
Landlord of rent with knowledge of the breach of any covenant of this Lease
shall not be deemed a waiver of such breach. The failure of Landlord to enforce
any of the Rules and Regulations set forth herein, or hereafter adopted, against
Tenant and/or any other tenant in the Building shall not be deemed a waiver of
any such Rules and Regulations. No provision of this Lease shall be deemed to
have been waived by Landlord, unless such waiver be in writing signed by
Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than
the monthly rent herein stipulated shall be deemed to be other than on the
account of the earliest stipulated rent, nor shall any endorsement or statement
on any check or any letter accompanying any check or payment of rent be deemed
an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such rent or
pursue any other remedy in this Lease provided.

      31.2. This Lease contains the entire agreement between the parties, and
any executory agreement hereafter made shall be ineffective to change, modify,
discharge or effect an abandonment of it in whole or in part unless such
executory agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.

interest in this Lease shall be assigned to a partnership (or to two (2) or more
persons, individually and as co-partners of a partnership) pursuant to Article
11 hereof (any such partnership and such persons are referred to in this Section
33.02 as "Partnership Tenant"), the following provisions of this Section 33.02
shall apply to such Partnership Tenant:

            (a) the liability of each of the parties comprising Partnership
      Tenant shall be joint and several, and

            (b) each of the parties comprising Partnership Tenant hereby
      consents in advance to, and agrees to be bound by, any written instrument
      which may hereafter be executed, changing, modifying or discharging this
      Lease, in whole or in part, or surrendering all or any part of the demised
      premises to Landlord, and by notices, demands, requests or other
      communications which may hereafter be given, by Partnership Tenant or any
      of the parties comprising Partnership Tenant, and

            (c) any bills, statements, notices, demands, requests or other
      communications given or rendered to Partnership Tenant or to any of the
      parties comprising Partnership Tenant shall be deemed given or rendered to
      Partnership Tenant and to all such parties and shall be binding upon
      Partnership Tenant and all such parties, and

            (d) if Partnership Tenant shall admit new partners, all of such new
      partners shall by their admission to Partnership Tenant, be deemed to have
      assumed performance of all of the terms, covenants and conditions of this
      Lease on Tenant's part to be observed and performed, and

            (e) Partnership Tenant shall give prompt notice to Landlord of the
      admission of any such new partners, and upon demand of Landlord, shall
      cause each such new partner to execute and deliver to Landlord an
      agreement in form satisfactory to Landlord, wherein each such new partner
      shall assume performance of all of the terms, covenants and conditions of
      this Lease on Tenant's part to be observed and performed (but neither
      Landlord's failure to request any such agreement nor the failure of any
      such new partner to execute or deliver any such

be deemed in default hereunder and this Lease and Tenant's obligation to pay
rent hereunder shall, except as provided in Section 34.03 hereof, in no wise be
affected, impaired or excused.

      33.2. If by reason of the circumstances contemplated by clauses (1)
through (5) of Section 34.01 hereof, Tenant shall be unable to fulfill any of
its obligation under this Lease other than the obligations to make any payment
of rent, additional rent or other charges, Tenant shall not be deemed in default
hereunder for so long as such circumstances continue to prevent Tenant from
fulfilling such obligations.

      33.3. If as a consequence of a circumstance or event contemplated by
Section 34.01 hereof or the performance by Landlord of any repair, alteration,
addition or improvement, the demised premises become untenantable and Tenant
actually discontinues the use thereof for a period in excess of ten (10)
Business Days, then, commencing on the eleventh (11th) Business Day of such
untenantability and continuing thereafter until the earlier of the date that (i)
the tenantability of the demised premises is restored, or (ii) Tenant resumes

business, the fixed annual rent and additional rent payable pursuant to Articles
3 and 4 hereof, shall be abated.

In the event of their being unable to agree upon such appointment within eighty
(80) days after the appointment of the second arbitrator, the third arbitrator
shall be selected by the parties themselves if they can agree thereon within a
further period of fifteen (15) days. If the parties do not so agree, then either
party, on behalf of both and on notice to the other, may request such
appointment by the American Arbitration Association (or organization successor
thereto) in accordance with its rules then prevailing or if the American
Arbitration Association (or such successor organization) shall fail to appoint
said third arbitrator within fifteen (15) days after such request is made, then
either party may apply on notice to the other, to the Superior Court Judicial

determination to both Landlord and Tenant within sixty (60) days of the
appointment of the first two arbitrators or sixty (60) days from the appointment

Section 47.04, and the fair market rent, so determined, shall be applied to
determine as above provided, whether the fixed annual rent shall be increased
pursuant to clause (i) of Section 47.02 hereof for the Second Extension Term. In
determining the fair market rent under this Article 47, the arbitrators shall
make the assumption that the length of the extension term hereunder (whether or
not the same is the case) is for a term length for which Landlord would, under
the then market conditions, be able to obtain the maximum rental amount.

      46.7. Each of the arbitrators selected as herein provided shall have at
least ten (l0) years experience in the leasing and renting of office space on

Connecticut.

      46.8. If Landlord notifies Tenant that the fixed annual rent for the
Second Extension Term shall be equal to the amount set forth in clause (ii) of

      46.9. In the event Landlord or Tenant initiates the appraisal process
pursuant to Section 47.04 hereof and as of the Commencement Date of the Second
Extension Term the amount of the fair market rent has not been determined,
Tenant shall pay the amount set forth in clause (ii) of Section 47.02 hereof and

                     SECOND AMENDMENT TO AGREEMENT OF LEASE

      THIS SECOND AMENDMENT TO AGREEMENT OF LEASE (this "Amendment") is
effective as of April 18, 1997, by and between STATE OF CALIFORNIA PUBLIC
EMPLOYEES' RETIREMENT SYSTEM, an Agency of the State of California ("Landlord"),
and OXFORD HEALTH PLANS, INC., a Delaware corporation ("Tenant"), with reference
to the following facts:

      A. Landlord's predecessor in interest, THE PRUDENTIAL INSURANCE COMPANY OF
AMERICA, a New Jersey Corporation ("Prudential"), as landlord, and Tenant, as
tenant, entered into that certain Agreement of Lease, dated as of June 16, 1993
(the "Original Lease"), as amended by that certain First Amendment to Lease,
dated as of May 26, 1995 (the "First Amendment," and together with the Original
Lease, the "Lease"). Each capitalized term used in this Amendment, but not
defined herein, shall have the meaning ascribed to it in the Lease.

      B. The demised premises under the Lease as of the date of this Amendment
consist of approximately 169,366 rentable square feet ("RSF") located in the
Building (the "Original Demised Premises").

      C. Landlord and Tenant desire to enter into this Amendment to expand the
demised premises by adding approximately 24,405 RSF located on the second floor
of the north wing of the Building (the "Expansion Space," and together with the
Original Demised Premises, the "Demised Premises" or "demised premises"), and to
make other related changes to the Lease, all as more particularly set forth in
this Amendment.

      THEREFORE, Landlord and Tenant agree that the Lease shall be amended as
follows:

      1. Premises.

      (a) Section 1.01 of the Lease shall be amended by expanding the Original
Demised Premises to include the Expansion Space, which Expansion Space is more
particularly depicted on Exhibit A attached hereto and incorporated herein.
Landlord and Tenant hereby agree that Landlord shall deliver exclusive
possession of the Expansion Space to Tenant, vacant and broom clean. Tenant
agrees to accept the Expansion Space "as is," and Tenant agrees that Landlord
has no obligation to demolish or construct any improvements in the Expansion
Space.

      (b) All references in the Lease to any number of square feet as the deemed
"rentable square foot area of the demised premises" (including, without
limitation, those references in Section 3.02(f) and Section 4.02(d)) shall be
deleted and replaced with "193,771 square feet."


                                      -1-
<PAGE>

      (c) Tenant is permitted to occupy the Expansion Space upon execution of
this Amendment by both parties, which occupancy shall be on all of the terms and
conditions of the Lease as amended by this Amendment; provided, however,
notwithstanding anything contained herein or in the Lease to the contrary,
Tenant shall not be obligated to pay any fixed annual rent with respect to the
Expansion Space prior to May 8, 1997.

      2. Term. Section 1.01 of the Lease shall be further amended by deleting
the last clause of that section (commencing with the words, "; for a term to
commence") and replacing it with the following:

            "; the term for the Original Demised Premises (as defined in that
      certain Second Amendment to Agreement of Lease (the "Second Amendment")
      dated as of April 18, 1997 between Landlord and Tenant) shall commence on
      July 1, 1993 (hereinafter referred to as the "Commencement Date") and
      shall expire on February 28, 2001 (hereinafter referred to as the
      "Expiration Date") or until such term shall sooner cease or terminate or
      be extended as hereinafter provided. The term for the Expansion Space (as
      defined in the Second Amendment) shall commence on April 18, 1997 and
      expire on February 28, 2010 (the "Expansion Space Expiration Date");
      provided, however, the term for the Expansion Space shall automatically
      terminate prior to the Expansion Space Expiration Date and coterminously
      with the expiration or earlier termination of this Lease with respect to
      the Original Demised Premises if this Lease terminates pursuant to the
      terms of this Lease with respect to the Original Demised Premises or in
      the event that this Lease expires prior to the Expansion Space Expiration
      Date due to Tenant's failure to exercise timely any option to extend the
      term for the Original Demised Premises."

      3. Rent.

            "52.01. Landlord hereby grants Tenant an irrevocable license,
      throughout the term of this Lease as the same may be extended, to use
      approximately one hundred (100) usable square feet of space for storage
      use, such space to be located on the lower level of the Building (the
      "Storage Space"), which Storage Space is more particularly depicted on
      Exhibit B attached hereto and incorporated herein. Tenant shall use the
      Storage Space only for "dead" storage of files, documents, furniture,
      trade fixtures and similar items, and any other use, including without
      limitation using the Storage Space as a work space or for operating
      equipment, is prohibited. Landlord has the right to relocate the Storage
      Space to another comparable storage space in the Building that has at
      least fifty (50) usable square feet, in a location that is reasonably
      satisfactory to Tenant, at any time upon twenty (20) business days prior
      written notice to Tenant, at Landlord's sole reasonable cost and expense.

            "52.02. Tenant's use of the Storage Space shall be on all of the
      terms and conditions of this Lease as amended by the Second Amendment;
      provided, however, Tenant shall not be obligated to pay any rent or
      additional rent with respect to its use of the Storage Space, and provided
      that Landlord shall have no obligations under Articles 12 or 21 of this
      Lease with respect to the Storage Space. Notwithstanding the foregoing,
      (1) Tenant shall have access


                                      -6-
<PAGE>

      to the storage space on a 24-hour day, seven-day per week basis and (2)
      Landlord shall not remove or alter any existing electrical lights, outlets
      or other electrical equipment existing in the Storage Space. Tenant shall
      not alter or add to any such electrical equipment without Landlord's prior
      written consent, which shall not be unreasonably withheld (based upon
      Landlord's reasonable determination of electrical equipment typically
      provided for comparable storage spaces). If Landlord consents thereto,
      then Landlord shall install such additional electrical equipment at
      Tenant's sole cost and expense, which cost and expense shall not be
      unreasonable.

            "52.03. Tenant's license to use the Storage Space pursuant to this
      Article shall automatically terminate upon the termination of this Lease,
      and Tenant shall vacate the Storage Space and surrender the Storage Space
      to Landlord clean and free of debris and in good state of repair, ordinary
      wear and tear and damage by fire or other casualty excepted. Ordinary wear
      and tear shall not include any damage or deterioration that would have
      been prevented by good maintenance practice by Tenant."

      10. Brokers. Tenant represents and warrants to Landlord that Tenant has
not incurred any liability for any commission or fee to any investment advisor,
real estate broker or finder, including, without limitation, Carson Crane
Incorporated ("CCI") or Alliance Partners, Inc. ("API"), in connection with this
Amendment. In the event any investment advisor, real estate broker or finder
makes any claim for any such commission or fee, Tenant shall indemnify, defend
and hold Landlord harmless from all claims, liabilities, losses, damages, costs
and expenses (including, without limitation, reasonable attorneys' fees) arising
from or based on any obligation or alleged obligation of Tenant to pay any such
commission or fee in connection with this Amendment. Tenant also represents and
warrants to Landlord that (1) no commissions or fees are due to Tenant (or any
broker or finder) with respect to this Amendment in connection with or arising
out of that certain Commission Assignment and Release Agreement (the "Commission
Agreement") dated June 24, 1993, entered into among CCI, API, Prudential and
Tenant, and (2) notwithstanding the provisions of the Commission Agreement
regarding payment of a Renewal Commission or an Expansion Commission (as those
terms are defined in the Commission Agreement), no commissions or fees will be
due to Tenant (or any broker or finder) in connection with or arising out of the
Commission Agreement with respect to the Expansion Space in the event Tenant
exercises a right under the Lease to extend or renew the term of the Lease with
respect to the Original Demised Premises. Furthermore, in the event CCI or API,
or any successors in interest thereto, makes any claim for any commission or fee
pursuant to the Commission Agreement (i) in connection with this Amendment, or
(ii) in connection with any Renewal Commission or Expansion Commission to the
extent that


                                      -7-
<PAGE>

such claim pertains or relates to the Expansion Space, Tenant shall indemnify,
defend and hold Landlord harmless from all claims, liabilities, losses, damages,
costs and expenses (including, without limitation, reasonable attorneys' fees)
arising from or based on any obligation or alleged obligation of Tenant or
Landlord to pay any such commission or fee.

      Notwithstanding the foregoing, the obligations of the parties under the
Commission Agreement with respect to any Renewal Commission or Expansion
Commission relating to the Original Demised Premises shall not be modified
hereby.

      Landlord represents and warrants to Tenant that Landlord has not incurred
any liability for any commission or fee to any investment advisor, real estate
broker or finder in connection with this Amendment, other than to Jones Lang
Wootton ("JLW"). Any commission or fee that Landlord owes to JLW shall be paid
in accordance with the terms of a separate agreement between Landlord and JLW.

      This Article 10 shall survive the expiration or earlier termination of the
Lease and this Amendment.

      11. Heating, Ventilating and Air-Conditioning Overtime Services. Landlord
acknowledges and agrees that Landlord's charges for overtime heating,
ventilating and air-conditioning services are specifically set forth in Article
21.01(b) of the Lease and, pursuant to such Article, Landlord covenants and
agrees that (i) it shall only increase such charges in proportion to increases
in Landlord's actual cost of rendering such services and (ii) in the event that
it shall be increasing the same it shall notify Tenant thereof in writing prior
to doing so.

      12. No Third Party Beneficiaries. Nothing contained in this Amendment
shall confer any rights or benefits upon any third parties.

      13. Notices. Article 31.01 of the Lease shall be amended by deleting the

Securityholder, and (assuming due authorization, execution and delivery by the
other Persons signatory thereto) this Agreement constitutes a legal, valid and

authorizations and other actions described in Section 3.03 have been obtained,

            SECTION 3.03. Governmental Consents and Approvals. The execution,
delivery and performance of this Agreement by such party do not and will not
require any consent, approval, authorization or other order of, action by,
filing with or notification to, any governmental authority, except such as may
be required by the HSR Act, applicable.

                                   ARTICLE IV

                              CORPORATE GOVERNANCE

            SECTION 4.01. Agreement to Vote. The Securityholders agree to vote
their shares, and the Company agrees to take all necessary measures, in order to
carry out the agreements set forth in this Article IV, and to prevent any action

until the Priceline Warrant expires unexercised. Thereafter, the Agreements
contained in this Article IV shall be of no further effect.

            SECTION 4.02. Size of Board. Initially, the Board shall consist of
seven (7) directors. If Priceline shall exercise the Priceline Warrant for not
less than 75% of the Warrant Shares, and as a result shall hold a majority of
the then outstanding Shares, the number of directors on the Board shall be
increased to nine (9). The number of directors shall not exceed nine (9), unless
the Board of Directors shall vote to increase the number in accordance with
Section 4.06.

"Independent Directors"), elected by Goldman Sachs, Arista Capital Partners, LP
("Arista Capital"), Michael Loeb and Jonathan Otto, voting on an equal basis
without reference to proportionate Shares ownership. Both such directors shall
qualify as "independent directors" pursuant to the definition set forth in Rule
4200(a)(14) of the National Association of Securities Dealers, substituting the
word "affiliate" for "subsidiaries" therein.

            (b) If and when the Board is expanded to nine (9) members, as
provided in Section 4.02, Priceline shall be represented by five (5) directors,
Walker Digital by one (1) director and Vulcan by one (1) director. The remaining
two (2) directors (the "Majority Directors") shall be elected by all the
Securityholders (excluding Priceline), voting cumulatively in proportion to
Share ownership. A representative of each of Goldman Sachs, Jonathan Otto and
Arista Capital may attend meetings of the Board in a nonvoting capacity and at
their own expense; provided that (i) no such representative shall serve in a
similar capacity or as a director or employee for any other company that is in a
business similar to that of the Company or that could be considered a competitor
of the Company and (ii) such representative shall keep all business of the Board
in the strictest confidence and, or requested by the Company, enter into a
confidentiality agreement.

            SECTION 4.04. Nomination and Election of Directors. The
Securityholders' initial nominees for the Board shall be as set forth in
Schedule III hereto. If not already named by the Company's existing Board, the
Securityholders shall act to elect such nominees as directors as soon as

held hereafter. Hereafter, the Securityholders shall make the nominations to
which they are entitled hereunder not later than 30 days prior to each annual
meeting of the Company's shareholders, and the Board shall be elected at such
meeting or by unanimous written consent in accordance herewith.

            SECTION 4.05. Vacancies. If, as a result of death, disability,
retirement, resignation, removal (with or without cause) or otherwise, there
shall exist or occur any vacancy in the Board:

            (a) if the departed director was nominated by Priceline, then
      Priceline,

            (b) if the departed director was nominated by Walker Digital, then
      Walker Digital,

            (c) if the departed director was nominated by Jonathan Otto, then
      Jonathan Otto,

            (d) if the departed director was nominated by Goldman Sachs, then
      Goldman Sachs,

            (e) if the departed director was nominated by Vulcan, then Vulcan,
      and

            (f) if the departed director was an independent director nominated
      by Goldman Sachs, Arista Capital, Michael Loeb and Jonathan Otto, then
      Goldman Sachs, Arista Capital, Michael Loeb and Jonathan Otto,
      collectively,


                                       14
<PAGE>

shall be entitled to designate in writing one nominee for election to fill such
vacancy. The Securityholders shall as soon as practicable after such nomination
is made act to elect such nominee to the Board. Any director elected pursuant to
this Section 4.05 shall serve until the next annual election of directors.

            SECTION 4.06. Voting. The Company's By-Laws shall provide that,
prior to the expiration unexercised of the Priceline Warrant, the affirmative
vote of the director or directors nominated by Priceline is required to approve
any of the following actions:

            (a) prior to the third anniversary of the Closing, any
      Recapitalization, business combination or sale of all or substantially all
      of the assets of the Company in which more than 50% of Company's Voting
      Interests are transferred;

            (b) any amendment, supplement or modification of any kind whatsoever
      to the Company's Certificate of Incorporation or By-laws, including any
      increase in the number of directors on the Board;

            (c) prior to the third anniversary of the Closing, the filing of a
      registration statement under the Securities Act or the making of any other
      public disclosure in connection with the commencement of an Initial Public
      Offering (excluding, for purposes of this paragraph only, the requirement
      that proceeds therefrom exceed $50 million); provided that such vote shall
      not be required in connection with an Initial Public Offering pursuant to
      Section 6.02(a);

            (d) any transactions with an Affiliate of the Company other than at
      fair market value in the ordinary course of business;

            (e) the dissolution and winding up of the Company; and

            (f) the voluntary initiation of an Insolvency Event in respect of
      the Company.

            The Securityholders shall vote their Shares in accordance with
Priceline's request on the above issues at any meeting of the Securityholders
where any of the above items are voted upon. Moreover, the Securityholders
hereby agree not to vote their shares in favor of any change to the By-laws of
the Company inconsistent with this Section 4.06.

            SECTION 4.07. Audit Committee. The Company shall establish and
maintain an Audit Committee, which shall consist of three members of the Board,

                                    ARTICLE V

                               TRANSFER OF SHARES

            SECTION 5.01. General Restriction. No Securityholder shall, directly
or indirectly, make or solicit any Sale of, or create, incur, solicit or assume
any Encumbrance with respect to, any Share, except in compliance with the
Securities Act and this Agreement.

            SECTION 5.02. Legends. (a) The Company shall affix to each
certificate evidencing Shares issued to Securityholders a legend in
substantially the following form:

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR
            OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE REGISTRATION
            REQUIREMENTS OF THE SECURITIES ACT OF 1933 OR AN EXEMPTION THEREFROM
            AND, IN EACH CASE, IN COMPLIANCE WITH APPLICABLE STATE SECURITIES
            LAWS.

            THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
            RESTRICTIONS ON TRANSFER AS SET FORTH IN A SECURITYHOLDERS_
            AGREEMENT DATED AS OF _______, 1999, AS IT MAY BE AMENDED FROM TIME
            TO TIME, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE
            OFFICES OF THE ISSUER. NO REGISTRATION OF TRANSFER OF THESE SHARES
            WILL BE MADE ON THE BOOKS OF THE ISSUER UNLESS AND UNTIL SUCH
            RESTRICTIONS SHALL HAVE BEEN COMPLIED WITH."


                                       16
<PAGE>

            (b) Any Securityholder with Shares issued prior to the date hereof
has delivered to the Company its certificates representing such Shares in
exchange for certificates representing such Shares bearing the legend set forth
in Section 5.02(a).

            (c) In the event that any Shares shall cease to be Restricted
Shares, the Company shall, upon the written request of the holder thereof, issue
to such holder a new certificate evidencing such Shares without the first
paragraph of the legend required by Section 5.02(a) endorsed thereon. In the
event that the Shares shall cease to be subject to the restrictions on transfer
set forth in this Agreement, the Company shall, upon the written request of the
holder thereof, issue to such holder a new certificate evidencing such Shares
without the legend required by the second paragraph of Section 5.02(a). Before
issuing a new certificate omitting part or all of the legend set forth in
Section 5.02(a), the Company may request an opinion of counsel reasonably
satisfactory to it to the effect that the restrictions discussed in the legend
to be omitted no longer apply to the Shares represented by such certificate.

            SECTION 5.03. Certain Restrictions on Transfer. (a) No
Securityholder shall, directly or indirectly (through the transfer of capital
stock of any Person that holds, or controls any Person that holds, such Shares)
make or solicit any Sale of, or create, incur or assume any Encumbrance with
respect to, any Share of Common Stock Beneficially Owned by such Securityholder,
other than

            (i) any Sale to a Permitted Transferee,

            (ii) during the Restricted Period, any Sale of Common Stock that is
      made in compliance with the procedures, and subject to the limitations,
      set forth in Sections 5.04 and 5.05,

            (iii) subject to compliance with Section 6.03(b), any Sale of Common
      Stock subsequent to the date that is 180 days after closing of the
      Company's Initial Public Offering,

            (iv) any Sale in connection with a merger of the Company or a Sale
      of all or substantially all of its assets or other similar business
      combination that has been approved by the Company's Board of Directors,

            (v) any Sale in connection with the merger of Priceline or a Sale of
      all or substantially all of its assets or other similar business
      combination that has been approved by Priceline's Board of Directors, or

            (vi) any Sale in connection with a public offering of equity
      securities of any Securityholder.


                                       17
<PAGE>

            Notwithstanding the foregoing, except as otherwise expressly
provided in this Agreement, all Sales permitted by the foregoing clauses (i)
through (iv) shall be subject to, and shall not be made other than in compliance
with, the provisions of Sections 5.01, 5.02, 5.03(b), 5.06 and 5.07.

            (b) No Sale of Shares to a Permitted Transferee shall be effective
if a purpose or effect of such transfer shall have been to circumvent the
provisions of this Section 5.03, Section 5.04 or Section 5.05. Each
Securityholder shall remain responsible for the performance of this Agreement by
each Permitted Transferee of such Securityholder to which Shares are
transferred, except if such Permitted Transferee received such Shares by will or
the laws of descent and distribution or if such Permitted Transferee is a
natural Person. If any Permitted Transferee to which Shares are transferred
pursuant to clause (i) of Section 5.03(a) is not a natural Person and ceases to
be a Permitted Transferee of the Securityholder from which or whom it acquired
such Shares pursuant to such provision, such Person shall reconvey such Shares
to such transferring Securityholder immediately before such Person ceases to be
a Permitted Transferee of such transferring Securityholder so long as such
Person knows of its upcoming change of status immediately prior thereto. If such
change of status is not known until after its occurrence, the former Permitted
Transferee shall make such transfer to such transferring Securityholder as soon
as practicable after the former Permitted Transferee receives notice thereof.

            (c) All restrictions on transfers of Shares imposed by this Article
V shall terminate 180 days after the closing of the Company's Initial Public
Offering or, if earlier, upon the expiration unexercised of the Priceline
Warrant.

            SECTION 5.04. Rights of First Refusal. (a) (i) If at any time during
the Restricted Period any Securityholder receives from or otherwise negotiates
with a Third Party a bona fide offer (an "Offer") to purchase for cash, Cash
Equivalents or Marketable Securities any of the Shares of Common Stock
Beneficially Owned or held by such Securityholder, and such Securityholder
intends to sell such Shares to such Third Party, such Securityholder (the
"Prospective Seller") shall provide the Company and each Securityholder other
than the Prospective Seller (each, an "Other Securityholder") with written
notice of such Offer (an "Offer Notice"). The Offer Notice shall identify the
Third Party making the Offer, the number of Shares covered by the Offer (the
"Offered Shares"), the price per Share at which a Sale is proposed to be made
(the "Offer Price"), the form of consideration proposed to be paid and all other
material terms and conditions of the Offer.

            (ii) If the Offer Price includes

            (A) any Marketable Securities, the value of such securities shall be
      determined by calculating a volume-weighted average of the closing prices
      of such securities over the ten trading-day period ending on the Price
      Determination Date on the market with the largest trading volume in such
      securities; or


                                       18
<PAGE>

            (B) any Cash Equivalents, the value of such Cash Equivalents shall
      be determined by reference to the closing price thereof on the market with
      the largest trading volume in such securities on the Price Determination
      Date.

            (b) (i) The receipt of an Offer Notice by the Company from a
Prospective Seller shall constitute an exclusive offer by such Prospective
Seller to sell to the Company any or all of the Offered Shares at the Offer
Price. Such offer shall remain open and irrevocable until expiration of thirty
days after receipt of such Offer Notice by the Company and the Other
Securityholders (the "Offer Period"). At any time prior to expiration of the
Offer Period, the Company shall have the right to accept the Prospective
Seller's offer as to any or all of the Offered Shares by giving a written notice
of election (the "Notice of Election") to the Prospective Seller with a copy to
the Other Securityholders.

            (ii) The receipt of an Offer Notice by the Other Securityholders
(excluding Priceline, whose rights are governed by subparagraph (b)(iii) below)
from a Prospective Seller shall constitute an offer by such Prospective Seller
to sell to such other Securityholders any or all of the Offered Shares not
purchased by the Company pursuant to subparagraph (b)(i) above at the Offer
Price pro rata, in accordance with the following formula. Each such Other
Securityholder shall be entitled to purchase, upon the terms specified in the
Offer Notice, a number of Shares equal to (x) the number of Offered Shares plus
the number of Shares being sold pursuant to Section 5.05 hereof, if any, less
the number of Shares the Company purchases pursuant to subparagraph (b)(i) above
multiplied by (y) a fraction, the numerator of which is the number of Voting
Interests Beneficially Owned by such Other Securityholder and the denominator of
which is the number of Voting Interests Beneficially Owned by all Other
Securityholders (excluding Priceline) who wish to purchase Offered Shares. If
any Other Securityholder wishes to purchase less than all the Shares such Other
Securityholder is entitled to purchase in accordance with the preceding
sentence, the Shares such Other Securityholder declines to purchase shall be
allocated among the Other Securityholders who wish to purchase such additional
Shares according to the same formula, mutatis mutandis. Each Other
Securityholder who wishes may accept the offer by sending a Notice of Election
to the Prospective Seller and the Company with a copy to the Other
Securityholders prior to expiration of the Offer Period. The Notice of Election
shall specify the maximum number of Shares an Other Securityholder is willing to
buy pursuant to this Section 5.04, if any, the number of Shares it wishes and is
entitled to sell pursuant to Section 5.05, if any, and any other terms and
conditions not inconsistent with this Agreement.

            (iii) The receipt of an Offer Notice by Priceline from a Prospective
Seller shall constitute an offer by such Prospective Seller to sell to Priceline
any or all of the Offered Shares at the Offer Price, to the extent such Shares
shall not have been purchased by the Company or the Other Securityholders
pursuant to subparagraphs (b)(i) and (b)(ii) above. Priceline may accept the
Prospective Seller's offer at any time prior to expiration of the Offer Period
by sending a


                                       19
<PAGE>

Notice of Election to the Prospective Seller and the Company, with a copy to the
Other Securityholders.

            (iv) If the Company or any Other Securityholder accepts the
Prospective Seller's offer in accordance with this Section 5.04(b) (an
"Accepting Party"), such Accepting Party shall purchase from the Prospective
Seller, and the Prospective Seller shall sell to such Accepting Party, such
number of Offered Shares as to which such Accepting Party shall have accepted
the Prospective Seller's offer pursuant to subparagraph (b)(i), (ii) or (iii)
above. The price per Share to be paid by such Accepting Party shall be the Offer
Price specified in the Offer Notice, payable in accordance with the terms of the
Offer; provided that the Accepting Party may pay the Offer Price with any
combination of cash, Cash Equivalents and Marketable Securities, to be valued as
provided in subparagraph (a)(ii) above.

            (c) The Prospective Seller and each Accepting Party shall select,
for consummation of the Sale of Offered Shares to such Accepting Party, a date
not later than 30 days (or longer, if the HSR Act so requires) after expiration
of the Offer Period. At the consummation of such Sale, the Prospective Seller
shall, against delivery by the relevant Accepting Party of the Offer Price
multiplied by the number of Shares being purchased by such Accepting Party, (i)
deliver to the Accepting Party certificates evidencing the Offered Shares being
sold plus the Shares being sold pursuant to Section 5.05, if any, duly endorsed
in blank or accompanied by written instruments of transfer in form satisfactory
to such Accepting Party duly executed by the Prospective Seller (or the selling
Other Securityholder, as the case may be) free and clear of any and all
Encumbrances (other than this Agreement), and (ii) assign all its rights under
this Agreement with respect to the Offered Shares being sold pursuant to an
instrument of assignment reasonably satisfactory to such Accepting Party.

            (d) In the event that (i) each Other Securityholder and the Company
shall have received an Offer Notice from a Prospective Seller but the
Prospective Seller shall not have received Notices of Acceptance indicating a
desire to purchase, in the aggregate, all the Offered Shares prior to expiration
of the Offer Period or (ii) an Accepting Party shall have given a Notice of
Election to the Prospective Seller but shall have failed to consummate, other
than as a result of the fault of the Prospective Seller, a purchase of the
Offered Shares he elected to purchase in such Notice of Election within the time
frame specified in paragraph (c) above (and neither the Company nor any Other
Securityholder shall have indicated an interest upon any such failure to buy
such Shares within ten Business Days of their receipt of a notice of such
failure from the Prospective Seller), then nothing in this Section 5.04 shall
limit the right of the Prospective Seller to make thereafter a Sale of, or
create an Encumbrance on, all Offered Shares not accepted for purchase by the
Company or the Other Securityholders pursuant to a Notice of Election; provided
that


                                       20
<PAGE>

            (A) the total number of Shares sold to the Company, the Other
      Securityholders and the Third Party who made the Offer shall be not less
      than the number of Offered Shares specified in the Offer Notice;

            (B) the total number of Shares sold by the Prospective Seller for
      his own account (i.e., not including Shares Beneficially Owned by Other
      Securityholders) to the Third Party who made the Offer shall be not more
      than the number of Offered Shares specified in the Offer Notice; and

            (C) all the Shares that are sold or otherwise disposed of by the
      Prospective Seller are sold (1) within 30 days (or longer, if the HSR Act
      so requires) after expiration of the Offer Period, (2) at an amount not
      less than the Offer Price included in such Offer Notice, (3) on the terms
      specified in the Offer Notice and (4) to the Third Party that made the
      Offer.

            (e) In the event that each Other Securityholder and the Company
shall have received an Offer Notice from a Prospective Seller, the Prospective
Seller shall not have received Notices of Acceptance indicating a desire to buy
all the Offered Shares prior to the expiration of the Offer Period and such
Prospective Seller shall not have sold the remaining Offered Shares before the
expiration of the period specified in subclause (d)(ii)(C)(1) above, then such
Prospective Seller shall not give another Offer Notice for a period of one year
from the day the Offer Notice was delivered.

            (f) Anything in this Section 5.04 or in Section 5.03 to the contrary
notwithstanding, the provisions of this Section 5.04 shall not be applicable to
any Sale or Encumbrance described in clause (i), (iii) or (iv) of Section
5.03(a).

            SECTION 5.05. Right to Participate in Certain Dispositions. (a) (i)
If, at any time during the Restricted Period, a Prospective Seller shall receive
an Offer from a Third Party or Parties, and shall propose to sell Common Stock
representing 25% or more of the Company's then outstanding Voting Interests, the
Prospective Seller shall provide the Offer Notice defined in Section 5.04 to the
Company and each of the Other Securityholders. Each of the Other Securityholders
shall have the right and option, for a period of 30 days concurrent with the
Offer Period specified in Section 5.04, to sell, pursuant to the Offer, up to
the same percentage of Voting Interests held or Beneficially Owned by it as the
Prospective Seller proposes to sell; provided that such right shall vest only
(i) if less than all the Offered Shares are sold to the Company, Other
Securityholders and Priceline pursuant to Section 5.04 and the Prospective
Seller consummates a Sale to the Third Party who made the Offer or an Affiliate
thereof or (ii) the Prospective Seller receives Notices of Election which, in
the aggregate, represent offers to buy all the Offered Shares and all the Shares
tendered by Other Securityholders pursuant to this Section 5.05. Each Other
Securityholder desiring to exercise such right shall, prior to the expiration of
the Offer Period, provide the Prospective Seller with a Notice of Election


                                       21
<PAGE>

specifying the number of Shares which such Other Securityholder has an interest
in selling pursuant to the Offer, and shall deliver to the Prospective Seller
(A) the certificate or certificates evidencing the Shares to be sold or
otherwise disposed of pursuant to such Offer by such Other Securityholder duly
endorsed in blank or accompanied by written instruments of transfer in form
satisfactory to the Prospective Seller executed by such Other Securityholder and
(B) an instrument of assignment reasonably satisfactory to the Prospective
Seller assigning, as of the consummation of the sale or other disposition to the
Third Party, all such Other Securityholder's rights under this Agreement with
respect to the Shares to be sold, and the instrument of assignment shall
constitute an irrevocable election by such Other Securityholder to authorize and
permit the Prospective Seller to sell such Shares, on behalf of such Other
Securityholder, pursuant to the Offer and in accordance herewith.

            (ii) If the Third Party making the Offer is unwilling to buy all the
Offered Shares plus all the Shares tendered by Other Securityholders in their
Notices of Election, then the Prospective Seller and each Other Securityholder
who wishes to sell shall be entitled to sell a number of Shares equal to (x) the
number of Shares the Third Party offeror is willing to buy (which shall not be
less than the number of Offered Shares), multiplied by (y) a fraction, the
numerator of which is the number of Voting Interests Beneficially Owned by such
Other Securityholder and the denominator of which is the total number of Voting
Interests Beneficially Owned by all Other Securityholders who wish to sell
Shares pursuant to the Offer. If any Other Securityholder wishes to sell less
than all the Shares he is entitled to sell in accordance with the preceding
sentence, the Shares he declines to sell shall be allocated among the
Prospective Seller and the Other Securityholders who wish to sell additional
Shares according to the same formula, mutatis mutandis. The Prospective Seller
shall not effect the Sale of any Shares pursuant to the Offer unless all the
Offered Shares and all of the Shares tendered to the Prospective Seller and
entitled to be sold pursuant to this Section 5.05 are simultaneously sold.

            (iii) As promptly as practicable after the consummation of any Sale
or other disposition of Shares to the Third Party pursuant to this Section 5.05,
the Prospective Seller shall remit to each of the Other Securityholders the
total sales price of the Shares of such Other Securityholders sold pursuant
thereto and return all certificates evidencing the unsold Shares that such Other
Securityholders delivered for Sale pursuant to this Section 5.05 and such Other
Securityholders' related instruments of assignment.

            (iv) If at the end of the Offer Period any Other Securityholder
shall not have given a Notice of Election indicating an interest in selling all
of the Shares such Other Securityholder would have been entitled to sell in
accordance with subparagraphs (a)(i) and (a)(ii) above (and delivered all other
required documents with respect thereto), such Other Securityholder shall be
deemed to have waived all its rights under this Section 5.05 with respect to the
Sale pursuant to the Offer of such Shares.


                                       22
<PAGE>

            (v) If at any time the Prospective Seller abandons the proposed Sale
pursuant to the Offer, or the Prospective Seller has not completed the Sale
pursuant to this Section 5.05 of the Offered Shares and the Shares which Other
Securityholders shall have tendered for Sale pursuant to this Section 5.05
within 30 days following expiration of the Offer Period, the Prospective Seller
shall promptly return to such Other Securityholders all certificates evidencing
the unsold Shares that such Other Securityholders delivered for Sale and such
Other Securityholders' related instruments of assignment.

            (vi) Except as expressly provided in this Section 5.05, no
Prospective Seller shall have any obligation to any Other Securityholder with
respect to the Sale or other disposition of any Shares owned by such Other
Securityholder in connection with this Section 5.05. Anything herein to the
contrary notwithstanding and irrespective of whether any Notice of Election
shall have been given, no Prospective Seller shall have any obligation to any
Other Securityholder to sell or otherwise dispose of any Offered Shares pursuant
to this Section 5.05 as a result of any decision by such Prospective Seller not
to accept or consummate any Offer or Sale or other disposition with respect to
the Offered Shares (it being understood that any and all such decisions shall be
made by such Prospective Seller in its sole discretion). No Other Securityholder
shall be entitled to sell or otherwise dispose of Shares directly to any Third
Party pursuant to an Offer (it being understood that all such Sales and other
dispositions shall be made only on the terms and pursuant to the procedures set
forth in this Article V).

            (b) Anything in this Section 5.05 or in Section 5.03 to the contrary
notwithstanding, the provisions of this Section 5.05 shall not be applicable to
any transfer described in clause (i), (iii) or (iv) of Section 5.03(a). Nothing
in this Section 5.05 shall affect any of the rights or obligations of any of the
Securityholders under any other provision of this Agreement.

            SECTION 5.06. Transferees to Execute Agreement. Each Securityholder
agrees that it will not, during the Restricted Period, directly or indirectly,
make any Sale of, or create, incur or assume any Encumbrance with respect to,
any Shares Beneficially Owned by such Securityholder unless prior to the
consummation of any such Sale or the creation, incurrence or assumption of such
Encumbrance, the Person to whom such Sale is proposed to be made or the Person
in whose favor such Encumbrance is proposed to be created, incurred or assumed
(a "Prospective Transferee") (i) executes and delivers this Agreement to the
Company and each Securityholder, and (ii) unless such Prospective Transferee is
a recognized institutional investor, delivers to the Company an opinion of
counsel, satisfactory in form and substance to the Company, to the effect that
the execution of this Agreement by such Prospective Transferee makes this
Agreement a legal, valid and binding obligation of such Prospective Transferee
enforceable against such Prospective Transferee in accordance with its terms.
Upon the execution and delivery by such Prospective Transferee of this Agreement
and, if required, the delivery of the opinion of counsel referred to in clause
(ii) of the preceding sentence, such Prospective Transferee shall be deemed a
"Securityholder" for purposes of this Agreement and


                                       23
<PAGE>

shall have the rights and be subject to the obligations of a Securityholder
under this Agreement, in each case with respect to the Shares Beneficially Owned
by such Prospective Transferee or in respect of which such Encumbrance shall
have been created, incurred or assumed.

            SECTION 5.07. Improper Sale or Encumbrance. Any attempt not in
compliance with this Agreement to make any Sale of, or create, incur or assume
any Encumbrance with respect to, any Shares shall be null and void and of no
force and effect, the purported transferee shall have no rights or privileges in
or with respect to the Company, and the Company shall not give any effect in the
Company's stock records to such attempted Sale or Encumbrance.

                                   ARTICLE VI

                               REGISTRATION RIGHTS

            SECTION 6.01. Incidental Registration. (a) If the Company at any
time proposes to register any Shares under the Securities Act for Sale in a
public offering, whether or not for its own account, on a form and in a manner
that would permit registration of Registrable Securities under the Securities
Act for Sale in such public offering, it shall each such time give prompt
written notice to all holders of Registrable Securities of its intention to do
so, specifying the form and manner and the other relevant facts involved in such
proposed registration (including, without limitation, the identity of the
managing underwriter, if applicable). Upon the written request of any such
holder of Registrable Securities delivered to the Company within 30 days after
such notice shall have been given to such holder (which request shall specify
the Registrable Securities intended to be disposed of by such holder and the
intended method of disposition thereof), the Company shall use its reasonable
best efforts to include in the registration statement relating to such public
offering all Registrable Securities that the Company has been so requested to
register by the holders of Registrable Securities, to the extent requisite to
permit the Sale of the Registrable Securities to be so registered in such public
offering; provided that:

            (i) no holder of Registrable Securities shall be entitled to
      register or sell Shares in the Company's Initial Public Offering;

            (ii) if, at any time after giving such written notice of its
      intention to register any of such Shares proposed to be registered by the
      Company and prior to the effective date of the registration statement
      filed in connection with such registration, the Company shall determine
      for any reason not to register such Shares, the Company may, at its
      election, give written notice of such determination to each holder of
      Registrable Securities that has requested to register Registrable
      Securities and thereupon the Company shall be relieved of its obligation
      to register any Registrable Securities in


                                       24
<PAGE>

      connection with such registration (but not from its obligation to pay the
      Registration Expenses in connection therewith to the extent provided in
      Section 6.01(b));

            (iii) if the proposed registration relates to an underwritten public
      offering and the managing underwriter or underwriters of such public
      offering shall advise the Company that, in its judgment, the number of
      Shares proposed to be included in such public offering should be limited
      because the inclusion of Registrable Securities is likely to materially
      and adversely affect the success of such public offering, then the Company
      shall promptly advise each such holder of Registrable Securities thereof
      and may require, by written notice to each such holder accompanying such
      advice, that, to the extent necessary to meet such limitation, all holders
      of Registrable Securities proposing to sell Shares in such public offering
      shall share pro rata in the number of Shares to be excluded from such
      offering, such sharing to be based on the respective numbers of
      Registrable Securities as to which registration has been requested by such
      holders; provided that all Registrable Securities that Priceline proposes
      to sell shall be excluded from such public offering before the Registrable
      Securities of any other party hereto; and provided further that the
      Company shall in no event be required to exclude Shares that it proposes
      to sell in such public offering; and

            (iv) the Company shall not be obligated to effect any registration
      of Registrable Securities under this Section 6.01 that is incidental to
      the registration of any of its Shares or other securities in connection
      with any merger, acquisition, exchange offer, dividend reinvestment plan
      or stock option or other employee benefit plan.

            (b) The Company shall pay all Registration Expenses in connection
with each registration of Registrable Securities effected by it pursuant to this
Section 6.01.

            SECTION 6.02. Registration on Request. (a) After the third
anniversary of the Closing, upon the written request of a Securityholder or
group of Securityholders (not including Priceline or Walker Digital) holding not
less than 25% of the then outstanding Shares (excluding any Warrant Shares
outstanding, whether held by Priceline or any transferee of Priceline),
requesting the Company to make an Initial Public Offering pursuant to a firm
commitment underwriting with a nationally recognized investment bank as lead
underwriter, the Company shall promptly give written notice of such request to
all Securityholders, and thereupon shall, as expeditiously as possible, use its
reasonable best efforts to register its Shares of Common Stock under the
Securities Act or, if so requested, register such Shares for listing on a
foreign securities exchange, and, in both cases, take such other actions as
shall be necessary to complete the Company's Initial Public Offering in
accordance with such request; provided that:

            (i) no holder of Registrable Securities shall be entitled to
      register or sell Shares in the Initial Public Offering;


                                       25
<PAGE>

            (ii) if, with respect to such Initial Public Offering, the managing
      underwriter, the Commission, the Securities Act or the rules and
      regulations thereunder, any other applicable laws, domestic or foreign, or
      the form on which any registration statement or similar document is to be
      filed, would require the conduct of an audit other than the regular audit
      conducted by the Company at the end of its fiscal year, the filing may be
      delayed until the completion of such regular audit (unless the party or
      parties requesting the Initial Public Offering agree to pay the expenses
      of the Company in connection with such an audit other than the regular
      audit); and

            (iii) if the Company, in its sole discretion, determines that the
      filing of a registration statement or commencement of an Initial Public
      Offering in the near future pursuant to this paragraph (a) would interfere
      with any financing, acquisition, corporate reorganization or other similar
      transaction involving the Company or any Subsidiary or that such
      registration or Initial Public Offering would require disclosure of
      non-public information that the Company deems advisable not to disclose,
      then the Company's obligation to file a registration statement or commence
      an Initial Public Offering shall be deferred for a period not to exceed 90
      days; provided that the Company shall not obtain such a deferral more than
      once in any twelve-month period.

            (b) If the Company has any class of securities registered under
Section 12 or 15(d) of the Exchange Act, upon the written request of Priceline,
or of a Securityholder or group of Securityholders holding not less than 25% of
the then outstanding Shares (excluding any Warrant Shares outstanding, whether
held by Priceline or any transferee of Priceline), requesting that the Company
effect the registration under the Securities Act of all or part of the
Registrable Securities held by such Securityholder or group of Securityholders
and specifying the intended method of disposition thereof, the Company shall
promptly give written notice of such requested registration to all other holders
of Registrable Securities, and thereupon shall, as expeditiously as possible,
use its reasonable best efforts to effect the registration under the Securities
Act of:

            (i) the Registrable Securities which the Company has been so
      requested to register by such Securityholder or Securityholders; and

            (ii) all other Registrable Securities that the Company has been
      requested to register by the holders of Registrable Securities by written
      request delivered to the Company within 30 days after the giving of such
      written notice by the Company (which request shall specify the intended
      method of disposition of such Registrable Securities);

provided that:

            (A) the Company shall be obligated to fulfill only two such
      registration requests by Priceline and one such registration request by
      each other holder of Registrable Securities (and for purposes of this
      clause (A), each holder of Registrable Securities


                                       26
<PAGE>

      whose Registrable Securities form part of a block as to which registration
      has been requested pursuant to this subsection (b) shall be deemed to have
      used its right to one registration request);

            (B) the Company shall not be obligated to file a registration
      statement relating to any registration request under this Section 6.02(b)
      within a period of nine months after the effective date of any other
      registration statement relating to any registration request under this
      Section 6.02(b) which was not effected on Form S-3 (or any successor or
      similar short-form registration statement) or relating to any registration
      effected under Section 6.01;

            (C) if, with respect to such registration statement, the managing
      underwriter, the Commission, the Securities Act or the rules and
      regulations thereunder, or the form on which the registration statement is
      to be filed, would require the conduct of an audit other than the regular
      audit conducted by the Company at the end of its fiscal year, the filing
      may be delayed until the completion of such regular audit (unless the
      holders of the Registrable Securities to be registered agree to pay the
      reasonable expenses of the Company in connection with such an audit other
      than the regular audit); and

            (D) if the Company, in its sole discretion, determines that the
      filing of a registration statement in the near future pursuant to this
      paragraph (b) would interfere with any financing, acquisition, corporate
      reorganization or other similar transaction involving the Company or any
      Subsidiary or that such registration would require disclosure of
      non-public information that the Company deems advisable not to disclose,
      then the Company's obligation to file a registration statement shall be
      deferred for a period not to exceed 90 days; provided that the Company
      shall not obtain such a deferral more than once in any twelve-month
      period.

            (c) If any registration requested pursuant to paragraph (b) which is
proposed by the Company to be effected by the filing of a registration statement
on Form S-3 (or any successor or similar short-form registration statement)
shall be in connection with an underwritten public offering, and if the managing
underwriter or underwriters shall advise the Company in writing that, in its
opinion, the use of another form of registration statement is of material
importance to the success of such proposed offering, then such registration
shall be effected on such other form.

            (d) An Initial Public Offering requested pursuant to paragraph (a)
shall be deemed to have been fulfilled when sufficient Shares have been sold to
meet the definition of Initial Public Offering hereunder and the Company's
Common Stock is trading on a major domestic or foreign securities exchange or
automated securities quotation system. A registration requested pursuant to
paragraph (b) shall be deemed to have been effected when the registration
statement pertaining thereto has become effective; provided that if, prior to
the earlier of the


                                       27
<PAGE>

completion of the distribution thereunder and 90 days after it has become
effective, the offering of Registrable Securities pursuant to such registration
is interfered with by any stop order, injunction or other order or requirement
of the Commission or other governmental agency or court, such registration will
be deemed not to have been effected, unless such order or requirement is
subsequently lifted and either the distribution is completed or 90 days from the
date of initial effectiveness (not counting the period during which such order
or requirement was in effect and interfered with the offering) expire.

            (e) If a requested Initial Public Offering or registration pursuant
to paragraph (b) involves an underwritten offering, the Company shall have the
right to select in good faith the investment banker or bankers and managers to
administer the offering, provided that such investment banker or bankers and
managers shall be satisfactory to (i) holders of a majority of the Shares, in
the case of paragraph (a) above, or (ii) holders of a majority of the
Registrable Securities which the Company has been requested to register, in the
case of paragraph (b) above.

            (f) If a requested registration pursuant to paragraph (b) involves
an underwritten offering and the managing underwriter or underwriters advise the
Company that, in their opinion, the number of securities requested to be
included in such registration (including securities of the Company which are not
Registrable Securities) exceeds the number which can be sold in such offering,
the Company shall include in such registration only the Registrable Securities
requested to be included in such registration pursuant to such paragraph (b). In
the event that the number of Registrable Securities requested to be included in
such registration exceeds the number which, in the opinion of such managing
underwriter or underwriters, can be sold, the number of such Registrable
Securities to be included in such registration shall be allocated pro rata among
the holders requesting registration pursuant to such paragraph (b) on the basis
of the relative number of Registrable Securities then requested for registration
by each such holder; provided that all Registrable Securities that Priceline
proposes to sell shall be excluded from such public offering before the
Registrable Securities of any other party hereto; and provided further that the
Company shall in no event be required to exclude Shares that it proposes to sell
in such public offering.

            SECTION 6.03. Registration Procedures. (a) If and whenever the
Company is required to use its reasonable best efforts to effect the
registration of any Registrable Securities under the Securities Act for Sale in
a public offering as provided in Section 6.01 or 6.02(b), the Company shall as
expeditiously as is reasonably practicable:

            (i) prepare and file with the Commission on any appropriate form a
      registration statement with respect to such Registrable Securities and use
      its reasonable best efforts to cause such registration statement to become
      effective;


                                       28
<PAGE>

            (ii) prepare and file with the Commission such amendments (including
      post-effective amendments) and supplements to such registration statement
      and the prospectus used in connection therewith as may be necessary to
      keep such registration statement effective and to comply with the
      provisions of the Securities Act with respect to the disposition of all
      Registrable Securities and other securities covered by such registration
      statement until the earlier of (A) such time as all such Registrable
      Securities and other securities have been disposed of in accordance with
      the intended methods of disposition by the seller or sellers thereof set
      forth in such registration statement and (B) the expiration of 90 days
      from the date such registration statement first becomes effective;

            (iii) furnish to each seller of such Registrable Securities such
      number of conformed copies of such registration statement and of each such
      amendment and supplement thereto (in each case including all exhibits),
      such number of copies of the prospectus included in such registration
      statement (including each preliminary prospectus and any summary
      prospectus), in conformity with the requirements of the Securities Act,
      such documents incorporated by reference in such registration statement or
      prospectus, and such other documents, as such seller may reasonably
      request in order to facilitate the sale or disposition of such Registrable
      Securities;

            (iv) use its reasonable best efforts to register or qualify all
      Registrable Securities and other securities covered by such registration
      statement under such other securities or "blue sky" laws of such
      jurisdictions as each seller shall reasonably request, and do any and all
      other acts and things that may be necessary to enable such seller to
      consummate the disposition in such jurisdictions of its Registrable
      Securities covered by such registration statement, except that the Company
      shall not for any such purpose be required to qualify generally to do
      business as a foreign corporation in any jurisdiction wherein it is not so
      qualified, or to subject itself to taxation in respect of doing business
      in any such jurisdiction, or to consent to general service of process in
      any such jurisdiction;

            (v) enter into such customary agreements (including an underwriting
      agreement in customary form), which may include indemnification provisions
      in favor of underwriters and other Persons in addition to, or in
      substitution for the provisions of Section 6.05 hereof, and take such
      other actions as sellers of a majority of shares of such Registrable
      Securities or the underwriters, if any, reasonably request in order to
      expedite or facilitate the disposition of such Registrable Securities;

            (vi) furnish to each seller of Registrable Securities a copy of (A)
      any opinion of counsel for the Company, dated the date of the closing
      under the underwriting agreement with respect to such Public Offering, in
      customary form and in form and scope reasonably satisfactory to the
      underwriter and its counsel, and (B) a "cold comfort" letter signed by the
      independent public accountants in customary form and covering matters of


                                       29
<PAGE>

      the type customarily covered by "cold comfort" letters and otherwise in
      such form and scope as the seller of such Registrable Securities shall
      reasonably request (provided that Registrable Securities constitute at
      least 25% of the securities covered by such registration statement, unless
      such a "cold comfort" letter or letters are provided to the Company or
      other selling holders or any underwriter in connection with such
      registration);

            (vii) immediately notify each seller of Registrable Securities
      covered by such registration statement at any time when a prospectus
      relating thereto is required to be delivered under the Securities Act, of
      the happening of any event as a result of which the prospectus included in
      such registration statement, as then in effect, includes an untrue
      statement of a material fact or omits to state any material fact required
      to be stated therein or necessary to make the statements therein not
      misleading in the light of the circumstances then existing or if it is
      necessary to amend or supplement such prospectus to comply with law, and
      at the request of any such seller prepare and furnish to such seller a
      reasonable number of copies of a supplement to or an amendment of such
      prospectus as may be necessary so that, as thereafter delivered to the
      purchasers of such Registrable Securities or other securities, such
      prospectus shall not include an 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 in the light of the
      circumstances then existing and shall otherwise comply in all material
      respects with law;

            (viii) otherwise use its reasonable best efforts to comply with all
      applicable rules and regulations of the Commission, and make available to
      its security holders, as soon as reasonably practicable, an earnings
      statement which shall satisfy the provisions of Section 11(a) of the
      Securities Act and the rules and regulations thereunder;

            (ix) use its reasonable best efforts to list such Shares on each
      securities exchange or quotation system on which Shares are then listed or
      quoted, if such Shares are not already so listed or quoted and if such
      listing is then permitted under the rules of such exchange or quotation
      system, and provide a transfer agent and registrar for such Registrable
      Securities not later than the effective date of such registration
      statement;

            (x) cooperate with the holders of Registrable Securities covered by
      the registration statement and the managing underwriter or agent, if any,
      to facilitate the timely preparation and delivery of certificates (not
      bearing any restrictive legends) representing securities to be sold under
      the registration statement, and enable such securities to be in such
      denominations and registered in such names as the managing underwriter or
      agent, if any, or such holders may request;

            (xi) notify counsel for the holders of Registrable Securities
      included in such registration statement and the managing underwriter or
      agent, immediately, and confirm


                                       30
<PAGE>

      the notice in writing (A) when the registration statement, or any
      post-effective amendment to the registration statement, shall have become
      effective, or any supplement to the prospectus or any amendment prospectus
      shall have been filed, (B) of the receipt of any comments from the
      Commission, (C) of any request of the Commission to amend the registration
      statement or amend or supplement the prospectus or for additional
      information, and (D) of the issuance by the Commission of any stop order
      suspending the effectiveness of the registration statement or of any order
      preventing or suspending the use of any preliminary prospectus, or of the
      suspension of the qualification of the registration statement for offering
      or sale in any jurisdiction, or of the institution or threatening of any
      proceedings for any of such purposes;

            (xii) use its reasonable best efforts to prevent the issuance of any
      stop order suspending the effectiveness of the registration statement or
      of any order preventing or suspending the use of any preliminary
      prospectus and, if any such order is issued, to obtain the withdrawal of
      any such order at the earliest possible moment;

            (xiii) if requested by the managing underwriter or underwriters,
      promptly incorporate in a prospectus supplement or post-effective
      amendment such information as the managing underwriter or underwriters or
      agent or such holder reasonably requests to be included therein,
      including, without limitation, with respect to the number of Registrable
      Securities being sold by such holder to such underwriter or underwriters
      or agent, the purchase price being paid therefor by such underwriter or
      underwriters or agent and with respect to any other terms of the
      underwritten offering of the Registrable Securities to be sold in such
      offering; and make all required filings of such prospectus supplement or
      post-effective amendment as soon as practicable after being notified of
      the matters incorporated in such prospectus supplement or post-effective
      amendment;

            (xiv) cooperate with each seller of Registrable Securities and each
      underwriter or agent participating in the disposition of such Registrable
      Securities and their respective counsel in connection with any filings
      required to be made with the National Association of Securities Dealers,
      Inc.; and

            (xv) issue to any underwriter to which any holder of Registrable
      Securities may sell such Registrable Securities in connection with any
      such registration (and to any direct or indirect transferee of any such
      underwriter) certificates evidencing Shares without the legends described
      in Section 5.02(a).

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish the Company with such information
regarding such seller and the distribution of such Registrable Securities as the
Company may from time to time reasonably request in writing and as shall be
required by law or by the Commission in connection therewith.


                                       31

            (b) Each holder of Registrable Securities agrees, if so required by
the managing underwriter or underwriters of an underwritten public offering of
Shares, not to effect any sale or distribution of Registrable Securities (other
than as part of a public offering other than the Initial Public Offering) during
the seven days prior to and 180 days after the effective date of the
registration statement with respect to such underwritten public offering;
provided that this Section 6.03(b) shall be applicable to the holders of
Registrable Securities only if all executive officers and directors and all
stockholders holding more than five percent (5%) of the then outstanding Common
Stock are subject to a similar restriction.

            Notwithstanding anything herein or in the Ancillary Agreements to
the contrary, Goldman Sachs and it Affiliates shall not be restricted from
engaging in any brokerage, investment advisory, financial advisory, anti-raid
advisory, merger advisory, financing, asset management, trading, market making,
arbitrage and other similar activities conducted in the ordinary course of its
or its Affiliates' business.

            (c) The Company agrees, if so required by the managing underwriter
or underwriters in connection with such public offering of Registrable
Securities pursuant to Section 6.01 or Section 6.02, not to effect any public
sale or distribution of any of its equity securities or securities convertible
into or exchangeable or exercisable for any of such equity securities during the
seven days prior to and the 180 days after the effective date of any
registration statement with respect to such public offering, except as part of
such public offering or except in connection with a stock option plan, stock
purchase plan, savings or similar plan, or an acquisition, merger or exchange
offer.

            (d) It is understood that, in any public offering of Registrable
Securities, in addition to the Shares (the "Initial Shares") the underwriters
have committed to purchase, the underwriting agreement may grant the
underwriters an option to purchase a number of additional shares (the "Option
Shares") equal to up to 15% of the initial Shares (or such other maximum amount
as the National Association of Securities Dealers, Inc. may then permit), solely
to cover over-allotments. Shares proposed to be sold by the Company and the
requesting holders shall be allocated between Initial Shares and Option Shares
as agreed or, in the absence of agreement, in the same manner as the Initial
Shares.

            SECTION 6.04. Preparation; Reasonable Investigation. In connection
with the preparation and filing of each registration statement registering
Registrable Securities under the Securities Act, the Company shall give the
holders of Registrable Securities on whose behalf such Registrable Securities
are to be so registered and their underwriters, if any, and their respective
counsel, accountants and other agents, upon reasonable prior notice and
according to a schedule acceptable to the management of the Company in its sole
discretion, access to its books and records and such opportunities to discuss
the business of the Company with its officers and the independent public
accountants who have issued a report on its financial statements as shall


                                       32
<PAGE>

be necessary, in the opinion of such holders and such underwriters or their
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

            SECTION 6.05. Indemnification for Liabilities Under the Securities
Laws. (a) In the event of any registration of any equity securities of the
Company under the Securities Act, the Company shall indemnify and hold harmless
the seller of any Registrable Securities covered by such registration statement,
its directors and officers, managers, general and limited partners (and
directors and officers thereof and, if such seller is a portfolio or investment
fund, its investment advisors), each other Person who participates as an
underwriter in the public offering of such securities, each officer and director
of each such underwriter, and each other Person, if any, who Controls such
seller or any such underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any losses, claims,
damages, liabilities and expenses, joint or several, to which such seller or any
such director or officer or participating or Controlling Person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages, liabilities or expenses (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which such securities were registered under the Securities Act, any preliminary
prospectus, final prospectus or summary prospectus included therein, or any
amendment or supplement thereto, or any document incorporated by reference
therein, or (ii) 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; and the Company shall reimburse such seller, and each such
director, officer, manager, partner, underwriter and Controlling Person for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided that the Company shall not be liable in any such case to
the extent that any such loss, claim, damage, liability (or action or proceeding
in respect thereof) or expense arises out of or is based upon (i) an untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity
with written information furnished to the Company for use in the preparation
thereof by such seller or underwriter, as the case may be, or (ii) an untrue
statement or alleged untrue statement or omission or alleged omission made in
any preliminary prospectus but notified to such seller and underwriter prior to
any Sale of Registrable Securities and subsequently corrected by the Company in
any final prospectus, amendment or supplement made available to such seller or
underwriter but which final prospectus, amendment or supplement was not used by
such seller or underwriter in the Sale of Registrable Securities that gave rise
to such loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller or any such
director, officer, underwriter or Controlling Person and shall survive the
transfer of such Shares by such seller.

            (b) The Company may require, as a condition to including any
Registrable Securities in any registration statement filed pursuant to Section
6.01 or Section 6.02, that the


                                       33
<PAGE>

Company shall have received an undertaking satisfactory to it from (i) the
prospective seller of such Registrable Securities, to indemnify and hold
harmless (in the same manner and to the same extent as set forth in Section
6.05(a), except that any such prospective seller shall not in any event be
liable for an amount in excess of the net proceeds of sale of such prospective
seller's Registrable Securities so to be sold together with any amounts payable
under Section 6.06 hereof) the Company, each such underwriter of such Shares,
each officer and director of each such underwriter and each other Person, if
any, who controls the Company or any such underwriter within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, and (ii)
each such underwriter of such Shares, to indemnify and hold harmless (in the
same manner and to the same extent as set forth in Section 6.05(a)) the Company,
each officer and director of the Company, each prospective seller, each officer
and director of each prospective seller and each other Person, if any, who
Controls the Company or any such prospective seller within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, with respect
to any statement in or omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus included therein,
or any amendment or supplement thereto, if such statement or omission was made
in reliance upon and in conformity with written information furnished by such
prospective seller or such underwriter, as the case may be, to the Company for
use in the preparation of such registration statement, preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of the Company or any such director, officer or Controlling Person and
shall survive the transfer of such Shares by such seller.

            (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action or proceeding (including any governmental
investigation) involving a claim referred to in Section 6.05(a) or (b), such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of
such action; provided that the failure of any indemnified party to give notice
as provided herein shall not relieve the indemnifying party of its obligations
under the preceding provisions of this Section 6.05, except to the extent that
the indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist in respect of such claim (in
which case, the indemnifying party shall not be liable for the fees and expenses
of more than one counsel for all sellers of Registrable Securities, or more than
one counsel for the underwriters in connection with any one action or separate
but similar or related actions), the indemnifying party shall be entitled to
participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified, to the extent that it may wish with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof. No indemnifying party shall
consent to entry of any


                                       34
<PAGE>

judgment or enter into any settlement which (i) does not include as an
unconditional term thereof, the giving by the claimant or plaintiff to the
Indemnified Party of a release from all liability in respect to such claim or
litigation or (ii) includes an admission of guilt on behalf of such Indemnified
Party.

            SECTION 6.06. Contribution. (a) If the indemnification provided for
in Section 6.05 is unavailable to the indemnified parties in respect of any
losses, claims, damages or liabilities referred to therein, then each
indemnifying party shall contribute to the amounts paid or payable by such
indemnified parties as a result of such losses, claims, damages or liabilities
(i) as between the Company and the holders of Registrable Securities covered by
a registration statement, on the one hand, and the underwriters, on the other,
in such proportion as is appropriate to reflect the relative benefits received
by the Company and such holders, on the one hand, and the underwriters, on the
other, from the Public Offering of the Registrable Securities, or if such
allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also the relative
fault of the Company and such holders, on the one hand, and of the underwriters,
on the other, in connection with the statements or omissions that resulted in
such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations, and (ii) as between the Company, on the one hand, and
each holder of Registrable Securities covered by a registration statement, on
the other, in such proportion as is appropriate to reflect the relative fault of
the Company and of each such holder in connection with such statements or
omissions, as well as any other relevant equitable considerations. The relative
benefits received by the Company and such holders, on the one hand, and the
underwriters, on the other, shall be deemed to be in the same proportion as the
total proceeds from the public offering (net of underwriting discounts and
commissions but before deducting expenses) received by the Company and such
holders bear to the total underwriting discounts and commissions received by the
underwriters. The relative fault of the Company and such holders, on the one
hand, and of the underwriters, on the other, 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 and such holders or by the
underwriters. The relative fault of the Company, on the one hand, and of each
such holder, on the other, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact
relates to information supplied by such party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

            (b) The Company and the holders of Registrable Securities agree that
it would not be just and equitable if contribution pursuant to this Section 6.06
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 the next preceding
paragraph. The amount paid or payable by an indemnifying party as a result of
the losses, claims, damages or liabilities referred to in the next preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses


                                       35
<PAGE>

reasonably incurred by the indemnified party in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this
Section 6.06, no underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the
public pursuant to such public offering 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 holder of
Registrable Securities shall be required to contribute any amount (together with
any amount payable under Section 6.05(b)) in excess of the amount by which the
net proceeds from the sale of Registrable Securities received by such holder
pursuant to such public offering exceeds the amount of any damages that such
holder 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. Each Securityholder's obligation to contribute
pursuant to this Section 6.06 is several in the proportion that the proceeds of
the public offering received by such Securityholder bears to the total proceeds
of the public offering received by all the Securityholders and not joint.

                                   ARTICLE VII

                              ADDITIONAL AGREEMENTS

            SECTION 7.01. New Investors to Execute Agreement. The Company shall
not, at any time prior to its Initial Public Offering, issue any shares of
Common Stock, or resell any shares of Common Stock held in its treasury, or
issue or resell any security convertible or exchangeable into Common Stock,
other than Common Stock that is issued to Priceline upon exercise of the
Priceline Warrant and Common Stock issued to the employees of the Company upon
exercise of options granted pursuant to the Company's Omnibus Employee Equity
Plan, unless prior to the consummation of any such issuance or Sale, each Person
to whom such security is proposed to be issued or sold executes and delivers
this Agreement to the Company and each Securityholder. Upon the execution and
delivery by any Person of this Agreement, Schedule I hereto shall be revised to
include the name of such Person and such Person shall be deemed a
"Securityholder" for purposes of this Agreement and shall have the rights and be
subject to the obligations of a Securityholder as such under this Agreement.

            SECTION 7.02. Rights to Purchase New Securities. (a) In the event
that the Company proposes to issue New Securities (prior to, and other than in
connection with, an Initial Public Offering), each Securityholder shall have the
right to purchase in lieu of the Person to whom the Company proposed to issue
such New Securities, in accordance with paragraph (b) below, a number of Shares
or other New Securities which the


                                       36
<PAGE>

Company proposes to issue equal to the product of (i) the total number or amount
of Shares or other New Securities which the Company proposes to issue at such
time and (ii) a fraction, the numerator of which shall be the total number of
Voting Interests which such Securityholder holds or beneficially owns at such
time, and the denominator of which shall be the sum of (i) the total number of
Voting Interests then outstanding plus (ii) the total number of Voting Interests
Priceline is entitled to purchase on the fifth anniversary date of the Priceline
Warrant or, if earlier, upon the occurrence of an Exercise Event under the
Priceline Warrant. The rights given by the Company under this Section 7.02 shall
terminate if unexercised within 30 days after receipt of the Notice of Issuance
referred to in paragraph (b) below.

            (b) In the event that the Company proposes to undertake an issuance
of New Securities (prior to, and other than in connection with, an Initial
Public Offering), it shall give written notice (a "Notice of Issuance") of its
intention to each Securityholder, describing all material terms of the New
Securities, the price and all material terms upon which the Company proposes to
issue such New Securities. Each Securityholder shall have 30 days from the date
of the Notice of Issuance to agree to purchase all or any portion of its pro
rata share of such New Securities (as determined pursuant to paragraph (a)
above) for the same consideration, if such consideration shall consist solely of
cash, or for cash, cash equivalents or marketable securities having an
equivalent value to the consideration payable by the Person to whom the Company
proposes to issue such New Securities at the time of payment, and otherwise upon
the terms specified in the Notice of Issuance by giving written notice to the
Company, and stating therein the quantity of New Securities to be purchased by
such Securityholder.

            SECTION 7.03. Further Assurances. Each of the parties hereto shall
use reasonable efforts to take, or cause to be taken, all appropriate action,
and to do, or cause to be done, all things necessary, proper or advisable under
applicable laws to consummate and make effective the transactions contemplated
hereunder, including, without limitation, using reasonable efforts to obtain all
licenses, permits, consents, approvals, authorizations, qualifications and
orders of the competent governmental entities. Without limiting the generality
of the foregoing, the parties shall, when required in order to effect the
transactions contemplated hereunder, make all necessary filings, and thereafter
make any other required or appropriate submissions, under the HSR Act and shall
supply as promptly as practicable to the appropriate governmental entity any
additional information and documentary material that may be requested pursuant
to the HSR Act. Each of the parties shall cooperate with the other when required
in order to effect the transactions contemplated hereunder. In case at any time
after the date hereof, any further action is necessary or desirable to carry out
the purposes of this Agreement, the proper officers and directors of each of the
parties shall use their reasonable best efforts to take all such action.

            SECTION 7.04. Access to Management. In addition to the rights
granted pursuant to Article VI of the Subscription Agreement, each
Securityholder shall have the right to consult with members of the Company's
management to such degree and in such manner as shall be sufficient to meet the
needs of such Securityholders' venture capital operating company requirements
under ERISA.

<PAGE>

            SECTION 7.05. Nominees. Notwithstanding anything herein to the
contrary, any Investor may hold its shares in nominee form through a reputable
securities depository.

            SECTION 7.06. Use of Names. Neither the Company nor any of its
Affiliates shall use the names of any Investor or any Affiliate of an Investor
in any press release, notice or other publication without the prior consent of
such Investor, which such consent shall not be unreasonably withheld; provided,
however, that each Investor acknowledges and agrees that the Company may issue a
press release upon the Closing under the Subscription Agreement stating the
total amount invested in the Company and a list of the Investors.

            SECTION 7.07. Aggregation of Shares. All shares held by The Goldman
Sachs Group, Inc. shall be aggregated with the Shares held by its Affiliates,
whether such Shares were acquired hereunder or pursuant to a transfer permitted
under Article V hereof, for the purpose of determining the availability of any
rights under this Agreement and any other applicable transaction agreement.

                                  ARTICLE VIII

                                 INDEMNIFICATION

            SECTION 8.01. Indemnification of Parties. (a) The Company shall
indemnify each Securityholder or affiliate thereof, and their respective
directors, managers, officers and employees (collectively, "Non-Company
Indemnitees") against, and hold each Non-Company Indemnitee harmless from, all
claims, suits, judgments, losses, damages, fines or costs (including reasonable
legal fees and expenses) ("Losses") arising out of or resulting from the breach
of any representation or warranty made by the Company herein or the breach of or
failure to perform any agreement or covenant made by the Company and contained
herein.

            (b) Each Securityholder shall indemnify the Company and its
directors, managers, officers and employees (collectively, the "Company
Indemnitees") and the other Non-Company Indemnitees against, and hold each
Company Indemnitee and other Non-Company Indemnitee harmless from, all Losses
resulting from or arising out of any breach of any representation or warranty
made by such party herein or the breach of or failure to perform any agreement
or covenant made by such party and contained herein.

            (c) Non-Company Indemnitees and Company Indemnitees (each, an
"Indemnified Party") shall give the party hereto from whom indemnification is
sought (the "Indemnifying Party") prompt written notice of any Losses as to
which such Indemnified Party may request indemnification hereunder. If the
Indemnifying Party acknowledges in writing its obligation to indemnify the
Indemnified Party hereunder against any such Losses, then the Indemnifying Party
shall be entitled to assume and control the defense of any claim, suit, or


                                       38
<PAGE>

demand by any third party ("Third Party Claim") at its expense and through
counsel of its choice if it gives notice of its intention to do so to the
Indemnified Party within five (5) days of the receipt of such notice from the
Indemnified Party; provided that if there exists or is reasonably likely to
exist a conflict or interest that would make it inappropriate in the judgment of
the Indemnified Party, in its sole and absolute discretion, for the same counsel
to represent both the Indemnified Party and the Indemnifying Party, then the
Indemnified Party shall be entitled to retain its own counsel, at the expense of
the Indemnifying Party. In the event the Indemnifying Party exercises the right
to undertake any such defense against any such Third Party Claim as provided
above, the Indemnified Party shall cooperate with the Indemnifying Party in such
defense and make available to the Indemnifying Party, at the Indemnifying
Party's expense, all witnesses, pertinent records, materials and information in
the Indemnified Party's possession or under the Indemnified Party's control
relating thereto as is reasonably required by the Indemnifying Party. Similarly,
in the event the Indemnified Party is, directly or indirectly, conducting the
defense against any such Third Party Claim, the Indemnifying Party shall
cooperate with the Indemnified Party in such defense and make available to the
Indemnified Party, at the Indemnified Party's expense, all such witnesses,
records, materials and information in the Indemnifying Party's possession or
under the Indemnifying Party's control relating thereto as is reasonably
required by the Indemnified Party. No such Third Party Claim may be settled by
the Indemnifying Party without the prior written consent of the Indemnified
Party.

            (d) In no event shall the Indemnifying Party be liable to an

action, suit or proceeding by its own counsel at its own expense. Priceline
shall have no claim of any kind against WebHouse based on or arising out of
WebHouse's handling of or decisions concerning any such action, suit,
proceeding, settlement, or compromise, and Priceline hereby irrevocably releases
WebHouse from any such claim, provided that WebHouse shall not enter into any

concerns the validity, enforceability (except in respect of granting immunity
from suit in connection with such settlement or compromise) or ownership of any
Licensed Trademarks, Licensed Patents or Other Licensed Property in the
Priceline Field or the New Merchandise Field without the prior written consent
of Priceline, which consent shall be at Priceline's sole discretion. WebHouse

in an amount proportional to the amount paid by each such Party with respect to
its costs and expenses in bringing such action, suit, or proceeding; provided,

            SECTION 8.01. Priceline to Control. Except as otherwise provided in
this Article VIII, Priceline shall prosecute and maintain all Licensed
Trademarks, Licensed Patents, and Other Licensed Intellectual Property in the
name of Priceline at the cost and expense of Priceline. WebHouse shall provide
reasonable cooperation to Priceline in connection with such prosecution or

WebHouse, Priceline shall file and obtain, at its own expense, additional

used by WebHouse in the Core Merchandise Field or the New Merchandise Field. Any
trademark applications filed and registrations obtained under the terms of this
Section 8.02 shall be in the name of Priceline and shall be included in the

consent of WebHouse, Priceline shall not abandon or allow to lapse any

            SECTION 9.01. Confidentiality. WebHouse will receive or learn from
Priceline, and Priceline's subsidiaries and affiliates, and Priceline will learn
from WebHouse, information, both orally and in writing, concerning the business
of Priceline or WebHouse, respectively, including, without limitation,
financial, technical and marketing information, and data and information related
to the development of technology and services, trade secrets, technology, plans,
methods, processes, specifications, models, protocols, techniques, research
projects, information management systems and software, whether protectable by
patent, copyright or other statutory means, relating to WebHouse's and
Priceline's business, as the case may be, and which information is deemed, in
the case of WebHouse, proprietary to WebHouse and, in the case of Priceline,
proprietary to Priceline. Both Parties hereby agree, as set forth below, to
protect such information, whether furnished before, on or after the date of this
Agreement, as it protects its own similar confidential information, but never
less than commercially reasonable efforts and not to disclose such information
to anyone except as otherwise provided for in this Agreement. Such information,
in whole or in part, together with analyses, compilations, programs, reports,
proposals, studies or any other documentation prepared by the Parties, as the
case may be, that contain or otherwise reflect or make reference to such
information, is hereinafter referred to as "Confidential Information". Both
Parties hereby agree that the Confidential Information will be used solely for
the purpose of this Agreement and not for any other purpose. Both Parties
further agree that any Confidential Information pertaining to the other Party is
the sole and exclusive property of such other Party, and that the receiving
Party shall not have any right, title, or interest in or to such Confidential
Information except as expressly provided in this Agreement. Both Parties further
agree to hold in the strictest confidence and not to disclose to anyone for any
reason Confidential Information pertaining to the other Party; provided that

            (a) such Confidential Information may be disclosed to the receiving
      Party's respective officers, directors, employees, agents, or
      representatives (collectively, "Representatives") on a "need to know"
      basis for the purpose of this Agreement on the condition that

                  (i) each such Representative will be informed by the receiving
            Party of the confidential nature of such Confidential Information
            and will agree to be bound by the terms of this Agreement and not to
            disclose the Confidential Information to any other person, and

                  (ii) both Parties agree to accept full responsibility for any
            breach of this Section 9.01 by its respective Representatives; and

[**]=Confidential Treatment requested for redacted portion


                                       15

            (b) Confidential Information pertaining to the other Party may be
      disclosed upon the prior written consent of the other Party.

Both Parties hereby agree, upon the request of the other Party, to promptly
deliver to the other Party the Confidential Information pertaining to such other
Party, without retaining any copies thereof.

            SECTION 9.02. Exceptions. The term "Confidential Information" shall
not include any information: (a) that at the time of disclosure or thereafter is
generally available to or known by the public (other than as a result of a
disclosure directly or indirectly by the receiving Party); (b) is independently
developed by the receiving Party, without reference to or use of, the
Confidential Information of the other Party; (c) was known by the receiving
Party as of the time of disclosure without breach of confidentiality; (d) is
lawfully learned from a third party not under obligation to the disclosing
Party. In the event that the receiving Party is requested pursuant to, or
required by, applicable law or regulation or by legal process to disclose
Confidential Information, the receiving Party shall (i) provide prompt written
notice to the other Party prior to such disclosure in order for such Party to
seek an appropriate protective order or other remedy, (ii) consult with the
other Party to resist or narrow the scope of such request or legal process and
(iii) in the event disclosure is required, use its best efforts to disclose only
that portion of Confidential Information that is legally required to be
disclosed and to ensure that all Confidential Information disclosed will be
accorded confidential treatment.

            SECTION 9.03. Unauthorized Disclosure. Each Party acknowledges and
confirms that the Confidential Information of each Party constitutes proprietary
information and trade secrets valuable to such Party, and that the unauthorized
use, loss or outside disclosure of such Confidential Information shall cause
irreparable injury to such Party. Each Party shall notify the other Party
immediately upon discovery of any unauthorized use or disclosure of Confidential
Information of the other Party, and will cooperate with the other Party in every
reasonable way to help regain possession of such Confidential Information and to
prevent its further unauthorized use. Each Party acknowledges that monetary
damages may not be a sufficient remedy for unauthorized disclosure of
Confidential Information and that the other Party shall be entitled, without
waiving other rights or remedies, to such injunctive or equitable relief as may
be deemed proper by a court of competent jurisdiction. Each Party shall be
entitled to recover reasonable attorney's fees for any action arising out of or
relating to a disclosure of its Confidential Information by the other Party.

defend, indemnify, and hold Priceline and its Affiliates and the respective
directors, officers, employees, and agents of Priceline harmless from and
against any and all losses, debts, liabilities, claims, demands, causes of
action and expenses (including attorney's fees and deposition and discovery
expenses) arising out of or resulting from (a) the breach by WebHouse of any of
its representations, warranties, covenants and agreements contained within this
Agreement, or (b) the carrying on of WebHouse's business other than those losses
that would constitute a breach of Priceline's representations and warranties set
forth herein.

            SECTION 11.02. Indemnification by Priceline. Priceline agrees to

suit or demand by any third party ("Third Party Claim") arising from or relating
to unauthorized acts or breaches of the terms of this Agreement, WebHouse and
Priceline (each, an "Indemnified Party") shall give the Party hereto from whom
indemnification is sought (the "Indemnifying Party") prompt written notice of
any Third Party Claim of which such Indemnified Party has knowledge concerning
any losses as to which such Indemnified Party may request indemnification
hereunder. If the Indemnifying Party acknowledges in writing its obligation to
indemnify the Indemnified Party hereunder against any losses that may result
from such Third Party Claim, then the Indemnifying Party shall be entitled to
assume and control the defense of such Third Party Claim at its expense and
through counsel of its choice if it gives notice of its intention to do so to
the Indemnified Party within five (5) days of the receipt of such notice from
the Indemnified Party; provided that if there exists or is reasonably likely to

[**]=Confidential Treatment requested for redacted portion


                                       19
<PAGE>

make it inappropriate in the judgment of the Indemnified Party, in its sole and
absolute discretion, for the same counsel to represent both the Indemnified
Party and the Indemnifying Party, then the Indemnified Party shall be entitled
to retain its own counsel, at the expense of the Indemnifying Party. In the
event the Indemnifying Party exercises the right to undertake any such defense
against any such Third Party Claim as provided above, the Indemnified Party
shall cooperate with the Indemnifying Party in such defense and make available
to the Indemnifying Party, at the Indemnifying Party's expense, all witnesses,
pertinent records, materials and information in the Indemnified Party's
possession or under the Indemnified Party's control relating thereto as is
reasonably required by the Indemnifying Party. Similarly, in the event the
Indemnified Party is, directly or indirectly, conducting the defense against any
such Third Party Claim, the Indemnifying Party shall cooperate with the
Indemnified Party in such defense and make available to the Indemnified Party,
at the Indemnified Party's expense, all such witnesses, records, materials and
information in the Indemnifying Party's possession or under the Indemnifying
Party's control relating thereto as is reasonably required by the Indemnified
Party. No such Third Party Claim may be settled by the Indemnifying Party
without the prior written consent of the Indemnified Party.

                                   THE WARRANT

            SECTION 2.01. Grant of Warrant. Issuer hereby grants to Grantee an
irrevocable, fully vested warrant (the "Warrant") to purchase 137,500,000 Shares
(the "Warrant Shares"), at a purchase price per Warrant Share initially equal to
$3.00 (the "Exercise Price"), subject to the terms and conditions set forth
herein. The number of shares constituting the Warrant Shares and the Exercise
Price are both subject to adjustment as set forth in Section 2.04 hereof.

            SECTION 2.02. Exercise of Warrant. (a) Subject to the conditions set
forth in Article VI, the Warrant may be exercised by Grantee, in whole or in
part, at any time after the fifth anniversary of the date of this Agreement or,
if earlier, the occurrence of an Exercise Event; provided that the Warrant shall
terminate and be of no further force and effect upon the earlier to occur of (i)
Closing of the final exercise of the Warrant, (ii) sixty (60) days after the
Issuer notifies Grantee of a willful and material breach by Grantee of Section
6.02 of the License Agreement, if such breach is not cured prior to the
expiration of such sixty (60) day period, and (iii) thirty days following the
fifth anniversary of the date hereof (the "Expiration Date"). Notwithstanding
the termination of the Warrant, Grantee shall be entitled to purchase those
Warrant Shares with respect to which it has issued an Exercise Notice (as
defined below) prior to the termination of the Warrant. The termination of the
Warrant shall not affect any rights hereunder which by their terms extend beyond
the date of such termination.

            (b) An "Exercise Event" shall occur for purposes of this Agreement
upon the occurrence of any of the following events:

[**]=Confidential Treatment requested for redacted portion


                                       7
<PAGE>

            (i) Issuer achieves Net Revenue of $[**] for any four-quarter period
      immediately preceding the date of measurement, or any shorter period in
      which Issuer achieves Net Revenue of $[**];

            (ii) the occurrence of an Insolvency Event in respect of Issuer;

            (iii) the adoption of a plan relating to the liquidation or
      dissolution of the Company;

            (iv)  the occurrence of a Change of Control, or Board approval of a
      transaction that would result in a Change of Control; or

            (v) Board approval of an Initial Public Offering.

Promptly upon the occurrence of any event described in clauses (i) and (ii)
above, and no later than fifteen (15) days prior to an event described in
clauses (iii) through (v) above, Issuer shall provide Grantee with notice of
such event together with the consolidated financial statements of Issuer, and
Grantee may exercise the Warrant until the Expiration Date.

            (c) The Warrant shall be exercised by written notice from Grantee to
Issuer (an "Exercise Notice") stating that the Warrant is being exercised and
setting forth: (i) a proposed closing date, which (subject to the earlier
satisfaction or waiver of the conditions set forth in Article VI) shall be:

            (A) in the case of an exercise upon the fifth anniversary hereof or
      pursuant to clause (b)(i) or (b)(ii) above, no earlier than fifteen (15)
      days after, and no later than thirty (30) days after, the date of delivery
      of such notice, and

            (B) in the case of an exercise pursuant to clause (b)(iii) through
      (b)(v) above, shall be the closing date of the transaction giving rise to
      the Exercise Event or such earlier date as shall be specified in the
      Exercise Notice,

on which date the Warrant Shares shall be issued; (ii) the number of Warrant
Shares to be purchased; and (iii) whether Grantee will purchase the Warrant
Shares with cash, shares of Grantee's common stock, par value $.01 per share
("Grantee Common Stock") or a combination thereof (including the relative
percentage of any combination). The Warrant shall be deemed to be exercised on
the date of delivery of the Exercise Notice, at which time the decision to
exercise the Warrant shall be irrevocable; provided that, in the case of an
exercise pursuant to clause (b)(iv) or (b)(v) above, the Warrant's exercise
shall be conditional upon the closing of the transaction giving rise to the
Exercise Event.

            (d) In the event that Grantee exercises the Warrant in part only,
upon such exercise Issuer shall execute and deliver to Grantee, at Issuer's
expense, a new Warrant exercisable for the number of Shares representing the
unexercised portion of the Warrant so exercised in part.

            SECTION 2.03. Form of Payment. (a) The Exercise Price may be paid in
cash, in shares of Grantee Common Stock or in any combination thereof at the
sole discretion of the Grantee. The number of shares of Grantee Common Stock to
be delivered in payment of all or a portion of the aggregate Exercise Price (the
"Stock Payment Amount") shall be determined by dividing the portion of the
aggregate Exercise Price to be paid in Grantee Common Stock by the average of
the closing prices of Grantee Common Stock quoted on the Nasdaq Stock Market
(or, if then traded on a national securities exchange, the average of the
closing prices of Grantee Common Stock on the principal national securities
exchange on which listed or, if quoted on the NASD OTC Bulletin Board, the
average of the means of the closing bid and asked price of Grantee Common Stock)
on each of the ten (10) trading days immediately preceding the date the Exercise
Notice is delivered.

            (b) In the event of any change in Grantee Common Stock or in the
number of outstanding shares of Grantee Common Stock between the date of an
Exercise Notice and the Closing by reason of a stock dividend, split-up,
recapitalization, combination, exchange of shares or similar transaction or any
other extraordinary change in the corporate or capital structure of Grantee
(including, without limitation, the declaration or payment of an extraordinary
dividend of cash, securities or other property), the type and number of shares
or securities to be delivered by Grantee in payment of the Stock Payment Amount
shall be adjusted appropriately so that Issuer shall receive upon payment of the
Stock Payment Amount the number and class of shares or other securities or
property that Issuer would have received in respect of Grantee Common Stock if
Grantee had paid the Stock Payment Amount immediately prior to such change.

            SECTION 2.04. Adjustments upon Share Issuances, Changes in
Capitalization, Etc. (a) In the event that Issuer shall issue or sell, prior to
the exercise in full or expiration of the Warrant, any Shares (except as
provided in paragraph (f) below) or Convertible Securities (as hereinafter
defined) or any rights or options to purchase Shares or Convertible Securities
for a consideration per share less than the Exercise Price in effect immediately
prior to such issue or sale, then forthwith upon such issue or sale the Exercise
Price shall be reduced to a price (calculated to the nearest $.0001) determined
by dividing (i) an amount equal to the sum of (A) the number of Shares
outstanding immediately prior to such issue or sale multiplied by the Exercise
Price then in effect, and (B) the consideration, if any, received by the Issuer
upon such issue or sale, by (ii) the total number of Shares outstanding
immediately after such issue or sale.

            (b) For the purposes of calculating any adjustment to the Exercise
Price pursuant to paragraph (a) above, the following provisions shall apply:

[**]=Confidential Treatment requested for redacted portion


                                       9
<PAGE>

            (i) In case at any time Issuer shall grant any rights to subscribe
      for, or any rights or options to purchase, Common Stock or any stock or
      other securities convertible into or exchangeable for Common Stock (such
      convertible or exchangeable stock or securities being herein called
      "Convertible Securities"), whether or not such rights or options or the
      right to convert or exchange any such Convertible Securities are
      immediately exercisable, and the price per Share for which Common Stock is
      issuable upon the exercise of such rights or options or upon conversion or
      exchange of such Convertible Securities

            (determined by dividing (A) the total amount, if any, received or
            receivable by Issuer as consideration for the granting of such
            rights or options, plus the minimum aggregate amount of additional
            consideration payable to Issuer upon the exercise of such rights or
            options, plus, in the case of any such rights or options which
            relate to such Convertible Securities, the minimum aggregate amount
            of additional consideration, if any, payable upon the issue or sale
            of such Convertible Securities and upon the conversion or exchange
            thereof, by (B) the total maximum number of Shares issuable upon the
            exercise of such rights or options or upon the conversion or
            exchange of all such Convertible Securities issuable upon the
            exercise of such rights or options)

      shall be less than the Exercise Price in effect immediately prior to the
      time of the granting of such rights or options, then the total maximum
      number of Shares issuable upon the exercise of such rights or options or
      upon conversion or exchange of the total maximum amount of such
      Convertible Securities issuable upon the exercise of such rights or
      options shall (as of the date of granting of such rights or options) be
      deemed to be outstanding and to have been issued for such price per Share.
      Except as provided in paragraph (e) of this Section 2.04, no further
      adjustments of the Exercise Price shall be made upon the actual issue of
      such Common Stock or of such Convertible Securities upon exercise of such
      rights or options or upon the actual issue of such Common Stock upon
      conversion or exchange of such Convertible Securities.

            (ii) In case at any time Issuer shall issue or sell any Convertible
      Securities, whether or not the rights to exchange or convert thereunder
      are immediately exercisable, and the price per Share for which Common
      Stock is issuable upon such conversion or exchange

            (determined by dividing (A) the total amount received or receivable
            by Issuer as consideration for the issue or sale of such Convertible
            Securities, plus the minimum aggregate amount of additional
            consideration, if any, payable to Issuer upon the

[**]=Confidential Treatment requested for redacted portion


                                       10
<PAGE>

            conversion or exchange thereof, by (B) the total maximum number of
            Shares issuable upon the conversion or exchange of all such
            Convertible Securities)

      shall be less than the Exercise Price in effect immediately prior to the
      time of such issue or sale, then the total maximum number of Shares
      issuable upon conversion or exchange of all such Convertible Securities
      shall (as of the date of the issue or sale of such Convertible Securities)
      be deemed to be outstanding and to have been issued for such price per
      Share, provided that (i) except as provided in paragraph (e) of this
      Section 2.04, no further adjustments of the Exercise Price shall be made
      upon the actual issue of such Common Stock upon conversion or exchange of
      such Convertible Securities, and (ii) if any such issue or sale of such
      Convertible Securities is made upon exercise of any rights to subscribe
      for or to purchase or of any option to purchase any such Convertible
      Securities for which adjustments of the Exercise Price have been or are to
      be made pursuant to other provisions of this paragraph (b), no further
      adjustment of the Exercise Price shall be made by reason of such issue or
      sale.

            (iii) In case at any time Issuer shall declare a dividend or make
      any other distribution upon any stock of the Company payable in Common
      Stock or Convertible Securities, any Common Stock or Convertible
      Securities, as the case may be, issuable in payment of such dividend or
      distribution shall be deemed to have been issued or sold without
      consideration.

            (iv) In case at any time any Share or Convertible Securities or any
      rights or options to purchase any Common Stock or Convertible Securities
      shall be issued or sold for cash, the consideration received therefor
      shall be deemed to be the amount received by Issuer therefor, without
      deduction therefrom of any expenses incurred or any underwriting
      commissions or concessions or discounts paid or allowed by Issuer in
      connection therewith. In case any Shares or Convertible Securities or any
      rights or options to purchase any Common Stock or Convertible Securities
      shall be issued or sold for a consideration other than cash, the amount of
      the consideration other than cash received by Issuer shall be deemed to be
      the fair value of such consideration as determined by the Board of
      Directors, without deduction therefrom of any expenses incurred or any
      underwriting commissions or concessions or discounts paid or allowed by
      Issuer in connection therewith. In case any Shares or Convertible
      Securities or any rights or options to purchase any Common Stock or
      Convertible Securities shall be issued in connection with any merger of
      another corporation into Issuer, the amount of consideration therefor
      shall be deemed to be the fair value of the assets of such merged
      corporation as determined by the Board of Directors after deducting
      therefrom all cash and other consideration (if any) paid by Issuer in
      connection with such merger.

                                       11
<PAGE>

            (v) In case at any time Issuer shall take a record of the holders of
      Common Stock for the purpose of entitling them (i) to receive a dividend
      or other distribution payable in Common Stock or Convertible Securities,
      or (ii) to subscribe for or purchase Common Stock or Convertible
      Securities, then such record date shall be deemed to be the date of the
      issue or sale of the Shares deemed to have been issued or sold upon the
      declaration of such dividend or the making of such other distribution or
      the date of the granting of such right of subscription or purchase, as the
      case may be.

            (c) In the event that Issuer shall make any distribution of its
assets upon or with respect to its Common Stock, as a liquidating or partial
liquidating dividend or otherwise, Grantee shall, upon any exercise of the
Warrant subsequent to the record date for such distribution or, in the absence
of a record date, subsequent to the date of such distribution, receive, in
addition to the Shares subscribed for, the amount of such assets (or, at the
option of Issuer, a sum equal to the value thereof at the time of distribution
as determined by the Board of Directors in its sole discretion) which would have
been distributed to Grantee if it had exercised the Warrant for that number of
Shares immediately prior to the record date for such distribution or, in the
absence of a record date, immediately prior to the date of such distribution.

            (d) In case at any time Issuer shall subdivide its outstanding
Shares into a greater number of Shares, the Exercise Price in effect immediately
prior to such subdivision shall be proportionately reduced and conversely, in
case the outstanding Shares of the Issuer shall be combined into a smaller
number of Shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased.

            (e) (i) If the purchase price provided for in any right or option
referred to in subparagraph (i) of paragraph (b) above, or the rate at which any
Convertible Securities referred to in subparagraph (i) or (ii) of said paragraph
(b) are convertible into or exchangeable for Common Stock, shall change or a
different purchase price or rate shall become effective at any time or from time
to time (other than under or by reason of provisions designed to protect against
dilution), then, upon such change becoming effective, the Exercise Price then in
effect hereunder shall forthwith be increased or decreased to such Exercise
Price as would have obtained had the adjustments made upon the granting or
issuance of such rights or options or Convertible Securities been made upon the
basis of (1) the issuance of the number of Shares theretofore actually delivered
upon the exercise of such options or rights or upon the conversion or exchange
of such Convertible Securities, and the total consideration received therefor,
and (2) the granting or issuance at the time of such change of any such options,
rights, or Convertible Securities then still outstanding for the consideration,
if any, received by the Company therefor and to be received on the basis of such
changed price.

            (ii) On the expiration of any right or option referred to in
subparagraph (i) of paragraph (b) above, or on the termination of any right to
convert or exchange any Convertible Securities referred to in subparagraph (i)
or (ii) of said paragraph (b), the Exercise Price shall

[**]=Confidential Treatment requested for redacted portion


                                       12
<PAGE>

forthwith be readjusted to such amount as would have obtained had the adjustment
made upon the granting or issuance of such rights or options or Convertible
Securities been made upon the basis of the issuance or sale of only the Shares
actually issued upon the exercise of such options or rights or upon the
conversion or exchange of such Convertible Securities.

            (iii) If the purchase price provided for in any right or option
referred to in subparagraph (i) of paragraph (b) above, or the rate at which any
Convertible Securities referred to in subparagraph (i) or (ii) of said paragraph
(b) are convertible into or exchangeable for Common Stock, shall change at any
time under or by reason of provisions with respect thereto designed to protect
against dilution, then in case of the delivery of Common Stock upon the exercise
of any such right or option or upon conversion or exchange of any such
Convertible Security, the Exercise Price then in effect hereunder shall
forthwith be decreased to such Exercise Price as would have obtained had the
adjustments made upon the issuance of such right or option or Convertible
Security been made upon the basis of the issuance of (and the total
consideration received for) the Shares so delivered.

            (f) Issuer shall not be required to make any adjustment of the
Exercise Price in the case of:

            (i)   the granting by Issuer of Employee Options,

            (ii) the issuance of Shares pursuant to the exercise of Employee
      Options, whether granted prior to or subsequent to the date hereof, or

            (iii) the issuance of such additional Shares as may be issuable upon
      the exercise of such options as a result of adjustment in the number of
      Shares covered by such options for stock dividends, stock splits or other
      changes in the capitalization of Issuer.

            (g) If any capital reorganization or reclassification of the Capital
Stock of Issuer, or consolidation or merger of Issuer with another corporation,
or the sale of all or substantially all of its assets to another corporation,
shall be effected in such a way that holders of Common Stock shall be entitled
to receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization, reclassification,
consolidation, merger or sale, Issuer or such successor or purchasing
corporation, as the case may be, shall execute with Grantee an agreement
providing that Grantee shall have the right thereafter and until the Expiration
Date to exercise the Warrant for the kind and amount of stock, securities or
assets receivable upon such reorganization, reclassification, consolidation,
merger or sale by a holder of the number of Shares for which the Warrant might
have been exercised immediately prior to such reorganization, reclassification,
consolidation, merger or sale, subject to adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Section
2.04.

            (h) (i) Whenever the Exercise Price is adjusted pursuant to the
provisions of this Section 2.04, the number of Warrant Shares for which the
Warrant is exercisable shall be adjusted so that it shall equal the number
determined by multiplying the number of Warrant Shares for which the Warrant was
exercisable immediately prior to such adjustment by a fraction, the numerator of
which shall be the Exercise Price in effect immediately prior to such
adjustment, and the denominator of which shall be the Exercise Price in effect
immediately thereafter.

            (ii) Issuer shall not be required to issue fractional Shares upon
any exercise of the Warrant following any adjustment in the number of Warrant
Shares for which the Warrant is exercisable pursuant to subparagraph (i) above.
If any fraction of a Share would, except for the provisions of this sentence, be
issuable on the exercise of the Warrant (or specified portion thereof), Issuer
shall pay an amount in cash calculated by it to be equal to the then current
market value per Share multiplied by such fraction, rounded to the nearest whole
cent.

            (i) The provisions of this Agreement, including, without limitation,
Sections 2.01, 2.02, 2.04, 2.05 and 5.04, shall apply with appropriate
adjustments to any securities for which the Warrant becomes exercisable pursuant
to this Section 2.04.

            SECTION 2.05. Right to Purchase New Securities. (a) In the event
that Issuer proposes to issue New Securities (prior to, and other than in
connection with, an Initial Public Offering), Grantee shall have the right to
purchase in lieu of the Person to whom Issuer proposed to issue such New
Securities, in accordance with paragraph (b) below, a number of Shares or other
New Securities which Issuer proposes to issue equal to the product of (i) the
total number or amount of Shares or other New Securities which Issuer proposes
to issue at such time and (ii) a fraction, the numerator of which shall be the
total number of Shares which Grantee owns or is entitled to purchase on the
fifth anniversary of the date of this Agreement or, if earlier, upon the
occurrence of an Exercise Event, pursuant to this Warrant, and the denominator
of which shall be the total number of Shares then outstanding plus the total
number of Shares which Grantee is entitled to purchase on the fifth anniversary
of the date of this Agreement or, if earlier upon the occurrence of an Exercise
Event, pursuant to this Warrant. The rights given by Issuer under this Section
2.05 shall terminate if unexercised within 30 days after receipt of the Notice
of Issuance referred to in paragraph (b) below.

            (b) In the event that Issuer proposes to undertake an issuance of
New Securities (prior to an Initial Public Offering), it shall give written
notice (a "Notice of Issuance") of its intention to Grantee, describing all
material terms of the New Securities, the price and all material terms upon
which Issuer proposes to issue such New Securities. The Grantee shall have 30
days from the date of the Notice of Issuance to agree to purchase all or any
portion of its pro rata share of such New Securities (as determined pursuant to
paragraph (a) above) for the same consideration, if such consideration shall

                      AIRLINE PARTICIPATION AGREEMENT


      THIS AGREEMENT (this "Agreement"), dated November 15, 1999, is by and
between priceline.com Incorporated, a Delaware corporation with an address
at Five High Ridge Park, Stamford, Connecticut 06905 ("Priceline"), and the
undersigned airline, whose principal place of business is set forth in the
notice provision of this Agreement ("Airline").

                           PRELIMINARY STATEMENT:

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

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

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

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

I.    Ticket Restrictions and Related Matters

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

      2.  All tickets issued by Priceline for carriage on Airline (each, a
          "Priceline Ticket"), as well as tickets issued by Priceline on
          its other Participating Carriers (as hereinafter defined) shall
          be subject to the restrictions listed in (a) through (h) below
          (the "Restrictions"):

          (a)  Except as otherwise provided in Paragraph IV.4 hereof, all
               Priceline Tickets will be non-refundable, non-endorsable and
               non-changeable;
          (b)  All travel will be round-trip with no stopovers or open-jaw
               travel permitted;
          (c)  Frequent Flyer mileage and upgrades will not be permitted;
               provided, Airline may offer such benefits to the extent that
               it is impractical to impose such frequent flyer restrictions
               on Priceline Tickets;
          (d)  Priceline customers must agree to (i) make up to one stop or
               connection on both their departing and return flights, (ii)
               accept a ticket on any carrier participating in Priceline's
               airline ticket service ("Participating Carrier"), and (iii)
               travel on any flight on the specified date of travel (x) for
               domestic U.S. flights, departing during the 6 a.m. - 10 p.m.
               time period unless the customer has specified a request to
               include flights departing outside those periods, and (y) for
               international flights, at any time (i.e., 12:01 a.m. to
               11:59 p.m.);
          (e)  All Priceline travel reservations and bookings shall be made
               without Priceline customers specifying a preferred (or
               requested) carrier, flight or time of day travel
               preference(s) on the specified date(s) of travel;
          (f)  All Priceline Tickets require instant ticketing guaranteed
               with a major credit card if Priceline is able to provide an
               airline ticket within the customer's requested price,
               departure and return date parameters;
          (g)  Priceline Ticket reservations are limited to no more than
               eight persons traveling in the same itinerary; and
          (h)  Except as otherwise provided herein, in any seven-day
               calendar period, a Priceline customer shall be limited to
               making one offer price for airline ticket(s) for a Trip. A
               "Trip" is defined as travel between the same airports on the
               same dates of travel. A Priceline customer may, within a
               seven-calendar day period, make an offer for travel in a
               different airport pair or on different dates of travel.
               Priceline will not knowingly sell a ticket to a Priceline
               customer in response to a second (or subsequent) offer for a
               Trip within a seven calendar day period; provided, that
               Priceline may sell a ticket in connection with a second
               offer if the Priceline customer (i) raises the offer by a
               minimum of $[**] and (ii) accepts, as part of the second
               offer, (x) a travel package which includes a hotel or
               rental car offer, or (y) a product or service co-marketed
               by Priceline such as a credit card or long distance telephone
               service or other co-marketing program.

      3.  If during any two consecutive months during the term of this
          Agreement, the number of tickets sold by Priceline on
          Participating Carriers that do not include a Saturday night stay
          is greater than [**]% of all tickets sold on all Participating
          Carriers through Priceline during such period, then Airline shall
          have the right to cause Priceline to include as part of the
          Restrictions, a Saturday night stay for all tickets sold on all
          Participating Carriers through Priceline; provided, however, that
          Airline's right to impose such restriction shall terminate and be
          of no further force or effect at such time as Delta Air Lines,
          Inc. ("Delta") no longer has a contractual right to cause
          Priceline to impose a Saturday night stay restriction for
          Priceline's airline ticket sales on all Participating Carriers.
          Additionally, in the event that Priceline licenses any of
          Priceline's proprietary software to Delta, Priceline will license
          such software to Airline on the same terms and conditions as
          apply to any license to Delta to the extent that contractual
          rights of Delta as of the date hereof do not prohibit such
          license (subject to any waiver by Delta); provided, however, that
          Priceline shall thereafter have the right unilaterally to modify
          or terminate such license to Airline if Priceline's license to
          Delta is similarly modified or terminated. Additionally, so long
          as, and only so long as, Delta shall have the contractual right
          to limit the number of second look offers under Paragraph I.2(h)
          to no more than 20 percent of first look offers, Priceline will
          comply with such Restriction, and Airline, shall hereby have an
          independent right to enforce such Restriction for all
          Participating Carriers. Subject to the foregoing, Priceline
          further agrees that it shall be prohibited from removing or
          materially modifying any of the Restrictions applicable to any
          Participating Carrier that will materially increase the usage of
          Priceline by business flyers without the prior written consent of
          Airline.

      4.  Airline may include, in addition to the Restrictions, other fare
          rules and conditions for Priceline Tickets issued on Airline such
          as advance purchase or Saturday night stay requirements. Subject
          to Paragraph II.2, Priceline also reserves the right after
          written notice to Airline to impose, on a non-discriminatory
          basis on all Participating Carriers, additional restrictions on
          tickets sold by Priceline, including a Saturday night stay
          requirement, as part of the Restrictions.

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

      6.  All Priceline Tickets issued for carriage on Airline shall be
          subject to the published conditions of carriage and the fare
          rules of Airline, to the extent such conditions and fare rules
          are not inconsistent with the Restrictions. Airline will honor
          all Priceline Tickets issued for travel on Airline in accordance
          with the Restrictions and other rules and conditions established
          by Airline for Priceline Tickets.

      7.  All tickets issued by Priceline on any Participating Carrier
          shall be subject to the Restrictions and any additional
          restrictions imposed by Priceline in accordance with the second
          sentence of Paragraph I.4.


II.   Priceline Ticket Reservations, Bookings, Payment and Fulfillment

      1.  Airline will file unpublished fares and rules for Priceline
          Tickets with the computer reservation system ("CRS") used by
          Priceline. Airline may file fares under Airline's two letter
          designation code on flights operated by other carriers.
          Notwithstanding the forgoing, Priceline will use best efforts to
          cooperate with Airline to identify and work toward the most
          efficient system selected by Airline, including Airline's
          internal reservation system, for the filing of fares for use by
          Priceline in the operation of its air travel service with
          Airline.

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

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

      4.  Subject to Paragraph III, upon locating an unpublished fare with
          inventory availability satisfying a Priceline customer's ticket
          request, Priceline shall immediately ticket the customer's ticket
          price against a valid credit card provided by the Priceline
          customer.

      5.  In all Priceline Ticket transactions, Priceline will be the
          merchant of record and will pay all associated merchant credit
          card fees. All Priceline Tickets sold on Airline will be settled
          through Airline Reporting Corporation ("ARC").

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

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

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

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

      10. In the event that Priceline is unable to fulfill an airline
          ticket request from unpublished fares and seat inventory provided
          from Participating Carriers in a manner not inconsistent with
          this Agreement, Priceline reserves the right to sell tickets on
          Airline using published fares used by travel agents generally as
          reflected in CRSs, in accordance with the rules and conditions
          associated with such fares and in accordance with an allocation
          method that allocates such purchases in proportion to the
          aggregate domestic or international market share (as applicable)
          offered by each Participating Carrier in the O&D requested;
          provided that the Participating Carrier has seats available for
          sale at the published fares comparable to the published fares
          available from other Participating Carriers in such O&D.

      11. [**]

          [**]

III.  Priceline Ticket Allocation Methodology

      Priceline will maintain an allocation methodology that determines when
participating airlines will be given the first opportunity to fill a
customer ticket request. Priceline will provide a first-look allocation
system whereby each Participating Carrier will be allocated first-looks for
each O&D's in proportion to its natural market share of all Participation
Carriers for such O&D's, as determine by a standard industry QSI
calculation. Airline acknowledges Delta Airlines' preexisting "first look"
advantage and agrees to participate in the Priceline Service on an interim
basis with Delta's "first look" allocation advantage. Priceline agrees to
negotiate expeditiously and in good faith with Delta to remove this first
look advantage relative to Airline. Priceline will notify Airline promptly
when the first look allocation advantage has been removed. Thereafter, in
no case will another Participating Carrier be given a first-look bias over
Airline. Priceline shall use its best efforts to establish a methodology,
acceptable to Airline, whereby Airline may indicate which flight to use to
fulfill a customer's request in the event that more than one flight (e.g.,
different departure times or different stops or connections) satisfies a
Priceline customer's request. Priceline agrees to fulfill all Priceline
first look ticket requests allocable to Airline at the "Highest Qualifying
Fare" available from Airline. In the interim period where Delta maintains
its first look advantage, carrier will receive second looks based upon O+D
QSI share and fulfillment at the "highest qualifying fare". As used herein,
the term "Highest Qualifying Fare" means the highest priced Airline
unpublished fare meeting the Priceline customer's offer price and other
terms, plus the amount of Priceline's minimum ticket margin, as established
from time to time by Priceline and notified to Airline. Once a first look
"level playing field" has been achieved, Priceline will allocate "second
through nth looks" in its sole discretion; provided, however, that
Priceline will not agree to provide any |Participating Carrier which has a
"level playing field" in the first look allocation system with an advantage
over the Airline in the second look allocation system; and provided
further, however, that Airline's contractual position with respect to
second looks shall be no less favorable than the contractual position of Delta.


IV.  Priceline Customer Service

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

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

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

     4.   The ticket Restrictions will apply to all tickets issued through
          the Priceline Service on Airline. Airline may waive, at its own
          cost and expense, one or more of the Restrictions set forth in
          Paragraphs I.2 (a)-(f) pursuant to a direct arrangement made by
          Airline with the applicable customer holding a Priceline Ticket.
          On an exception basis where necessary or appropriate to address
          an escalating customer service issue of any individual customer,
          Priceline may refund the price of a Priceline Ticket applicable
          to such customer. At Airlines' request, Priceline shall provide
          Airline with a monthly report detailing the number and amount of
          refunded Priceline Tickets involving air transportation services
          on Airline. Priceline and Airline will jointly develop the
          guidelines upon which such exception refunds will be governed.

V.   Confidentiality

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

     2.   The obligations of a recipient party with respect to Confidential
          Information shall remain in effect during and after the term of
          this Agreement (including any renewals or extensions hereof) and
          for a period of one (1) year thereafter, except to the extent
          such data:

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

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

          (c)  is necessary to comply with applicable law or the order or
               other legal process of any court, governmental or similar
               authority having jurisdiction over the recipient. Both
               parties hereto acknowledges that the other party may be
               required to file this Agreement with the Securities and
               Exchange Commission ("SEC"), as required by federal
               securities laws, and that such filing shall not be deemed a
               violation of the provisions of this Article V; provided,
               that either party may request confidential treatment of
               provisions of this Agreement; or

          (d)  was in the possession of the recipient party prior to the
               date of disclosure by the other party, as shown by written
               records of the recipient party; provided, however, that both
               parties acknowledge and confirm that they began exchanging
               data on April 1, 1998.

     3.   Except as otherwise specifically provided in Section 2(c) of this
          Paragraph V with respect to either party's filing requirements
          with the SEC, in the event that the recipient becomes legally
          compelled to disclose any of such Confidential Information by any
          governmental body or court, recipient will provide the disclosing
          party with prompt notice so that the disclosing party may seek a
          protective order or other appropriate remedy and/or waive
          compliance (in writing) with the provisions hereof. In the event
          that such protective order or other remedy is not obtained, or
          the disclosing party waives (in writing) compliance with the
          provisions hereof, recipient will furnish only that portion of
          such Confidential Material which is legally required and will
          exercise its reasonable business efforts to obtain appropriate
          assurance that confidential treatment will be accorded such
          Confidential Information

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

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

     6.   Nothing contained herein shall be construed to prevent Airline
          from competing, directly or indirectly, with Priceline. Priceline
          shall not provide any Confidential Information to Airline that
          would in any way prohibit or inhibit such competition.

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

VI.   Proprietary Marks

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

VII.  Reporting

      Priceline will provide monthly reports in a format designated by
      Airline summarizing (i) information concerning each ticket issued by
      Priceline on Airline; (ii) aggregate information (i.e. non airline
      specific) for all tickets issued by Priceline in each O&D that
      Airline participates; and (iii) aggregate information for all

            the address, phone and facsimile number of its designated
            recipient in accordance with this Paragraph XII(3).

      4.    This Agreement supersedes and replaces all previous understandings
            or agreement, whether oral or in any written form, with respect to
            the subject matter addressed herein. The captions in this
            Agreement are for convenience only and do not alter any terms of
            this Agreement.

      5.    This Agreement may be amended or modified only by a written
            amendment executed by the parties.

      6.    The formation, construction, performance and validity of
            this Agreement shall be governed by the internal laws of the
            State of New York. Each party agrees that any civil suit or
            action brought against it as a result of any of its
            obligations under this Agreement may be brought against it
            either in the state or federal courts of the principal place
            of business of either party, and each party hereby
            irrevocably submits to the jurisdiction of such courts and
            irrevocably waives, to the fullest extent permitted by law,
            any objections that it may now or hereafter have to the
            laying of the venue of such civil suit or action and any
            claim that such civil suit or action has been brought in an
            inconvenient forum, and each party further agrees that final
            judgment in any such civil suit or action shall be
            conclusive and binding upon it and shall be enforceable
            against it by suit upon such judgment in any court of
            competent jurisdiction.

       7.   This Agreement may be executed in counterparts, each of
            which shall be deemed an original, and together, shall
            constitute one and the same instrument. Execution may be
            effected by delivery of facsimiles of signature pages (and
            the parties shall follow such delivery by prompt delivery of
            originals of such pages).

       8.   No party will in any manner or by any device, either
            directly or indirectly, act in violation of any applicable
            law, governmental order or regulation, including, but not
            limited to, those concerning advertisement of air
            transportation services. Priceline shall comply at all times
            with the provisions of Airline's tariffs (except where such
            tariffs are specifically amended by Airline under the terms
            of this Agreement) and the terms of the ARC Agent Reporting
            Agreement and any addenda thereto.

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

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

      11.   This Agreement shall not be deemed to create any partnership
            or joint venture between Airline and Priceline, or to create
            any rights in favor of any person or entity other than the
            parties hereto. This Agreement is for the sole benefit of
            the parties and nothing herein expressed or implied shall
            give or be construed to give any other person any legal or
            equitable rights hereunder

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

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

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

                         [SIGNATURE PAGE TO FOLLOW]

     IN WITNESS WHEREOF, the parties have executed and delivered this

                (i)   The Warrant Holder will have the right at any time
                      during the first Measuring Period (as defined in
                      Section 4(c) below), to exercise Warrants, subject to
                      adjustment as provided in Section 10 hereof, equal to
                      [**]% or [**]% of the Shares, as applicable, provided
                      that, except as otherwise provided in Sections
                      4(b)(iii) and 4(b)(iv) hereof, (i) the right to
                      exercise Warrants for [**]% of the Shares shall not
                      accrue unless and until the Company has, on an
                      aggregated basis during the first Measuring Period,
                      received at least $[**] million of Net Revenues (as
                      also defined in Section 4(c) below) from tickets sold
                      during such Measuring Period for travel on the
                      Warrant Holder, its subsidiaries and/or on the
                      Warrant Holder's code share partners using Warrant
                      Holder's code (collectively, "Warrant Holder and its
                      Code Share Partners"), and (ii) the right to exercise
                      Warrants for [**]% of the Shares shall not accrue
                      unless and until the Company has, on an aggregated
                      basis during the first Measuring Period, received at
                      least $[**] million of Net Revenues from tickets sold
                      during such Measuring Period for travel on the
                      Warrant Holder and its Code Share Partners.

                (ii)  During the period which Warrant Holder is subject to a

                      Revenues, for the purpose of measurement toward early
                      exercise in the first Measuring Period, will be multiplied
                      by a factor of three (3). Additionally, in the event that
                      Warrant Holder remains subject to a first look
                      disadvantage relative to Delta Air Lines, Inc. on [**],
                      Warrant Holder will be entitled to exercise Warrants for
                      [**]% of the Shares beginning [**]. Any such early
                      exercise will be offset against the early exercise rights
                      for the first Measuring Period.

                (iii) The Warrant Holder will have the right at any time
                      during the second Measuring Period and all remaining
                      Measuring Periods thereafter, to exercise Warrants,
                      subject to adjustment as provided in Section 10
                      hereof, equal to [**]% or [**]% of the Shares, as
                      applicable, or such lesser percentage of the Shares
                      as shall constitute all of the remaining Shares not
                      then exercisable; provided that (i) the right to
                      exercise Warrants for [**]% of such Shares shall not
                      accrue unless and until the Company has, on an
                      aggregated basis during the applicable Measuring
                      Period, received at least $[**] million of Net
                      Revenues from tickets sold during such Measuring
                      Period for travel on the Warrant Holder and its Code
                      Share Partners, and (ii) the right to exercise
                      Warrants for [**]% of such Shares shall not accrue
                      unless and until the Company has, on an aggregated
                      basis during the applicable Measuring Period,
                      received at least $[**] million of Net Revenues from
                      tickets sold during such Measuring Period for travel
                      on the Warrant Holder and its Code Share Partners.

                (iv)  Notwithstanding the Net Revenue benchmarks specified
                      in clauses (i) and (ii) of this Section 4(b) for the
                      early exercisability of Warrants, if, in any
                      Measuring Period, the Company fails to achieve the
                      minimum Net Revenues from ticket sales for travel on
                      Warrant Holder and its Code Share Partners necessary
                      to enable Warrant Holder to exercise Warrants for the
                      [**]% or [**]% portion of Shares that would otherwise
                      become exercisable if such benchmarks were achieved
                      during such Measuring Period, then, effective on the
                      last day of such Measuring Period and thereafter,
                      Warrant Holder (i) shall have the right to exercise
                      Warrants for the [**]% portion of Warrants that would
                      otherwise become exercisable upon achieving the
                      corresponding Net Revenue benchmark for such
                      Measuring Period, if Warrant Holders and its Code
                      Share Partners' percentage of the aggregate of all
                      ticket sale revenues (calculated using the same
                      methodology used to calculate Net Revenue hereunder)
                      received by the Company for U.S. originating O&D's
                      for such Measuring Period equals or exceeds [**]% of
                      Warrant Holder's Fair Share (as defined in Section
                      4(c) below)(the "[**]% Fair Share Threshold"), and (ii)
                      shall have the right to exercise Warrants for the [**]%
                      portion of Warrants that would otherwise become
                      exercisable upon achieving the corresponding Net
                      Revenue benchmark for such Measuring Period, if
                      Warrant Holder's and its Code Share Partners'
                      percentage of the aggregate of all ticket sale
                      revenues received by the Company for U.S. originating
                      O&D's for such Measuring Period equals or exceeds
                      [**]% of Warrant Holder's Fair Share (the "[**]% Fair
                      Share Threshold"). For purposes of determining
                      whether Warrant Holder achieves the [**]% Fair Share
                      Threshold and/or the [**]% Fair Share Threshold for
                      the first, and only the first, Measuring Period, the
                      parties shall calculate Warrant Holder's and its Code
                      Share Partners' percentage of the Company's ticket
                      sale revenues for U.S. originating O&D's for such
                      period based on either (i) their percentage of the
                      aggregate of all ticket sale revenues received by the
                      Company for ticket sales for U.S. originating O&D's
                      during the entire first Measuring Period, or (ii)
                      their percentage of the aggregate of all ticket sale
                      revenues received by the Company for ticket sales for
                      U.S. originating O&D's during the final six (6)
                      months of the First Measuring Period, whichever is
                      more favorable for the Warrant Holder.

                (v)   In the event that the Company does not achieve the
                      $[**] million Net Revenue benchmark specified in
                      clauses (i) of this Section 4(b) and Warrant Holder
                      does not achieve the [**]% Fair Share Threshold
                      specified in clause (iii) of this Section 4(b) for
                      the early exercisability of Warrants for the first
                      Measuring Period, Warrant Holder shall have the right
                      upon completion of the first Measuring Period and
                      thereafter to exercise Warrants for the [**]% portion
                      of Warrants that would otherwise become exercisable
                      upon the Company's achieving the $[**] million Net
                      Revenue benchmark or Warrant Holder's achieving the
                      [**]% Fair Share Threshold for such Measuring Period,
                      if, during the entire term of the first Measuring
                      Period, Warrant Holder does not voluntarily
                      participate in any name-your-price airline ticket
                      service other than the Company's and its affiliates'
                      airline ticket services.

                (vi)  In the event that the Company does not achieve the
                      $[**] million Net Revenue benchmark specified in
                      clause (ii) of this Section 4(b) and Warrant Holder
                      does not achieve the [**]% Fair Share Threshold
                      specified in clause (iii) of this Section 4(b) for
                      the early exercisability of Warrants for the second
                      Measuring Period, Warrant Holder shall have the right
                      upon completion of the second Measuring Period and
                      thereafter to exercise Warrants for [**]% of the [**]%
                      portion of the Warrants that would have otherwise
                      become exercisable upon the Company's achieving the
                      $[**] million Net Revenue benchmark or Warrant
                      Holder's achieving the [**]% Fair Share Threshold for
                      such Measuring Period, if, during the entire term of
                      the second Measuring Period, Warrant Holder does not
                      voluntarily participate in any name-your-price
                      airline ticket service other than the Company's and
                      its affiliates' airline ticket services.

                (vii) In the event that the Company does not achieve the
                      $[**] million Net Revenue benchmark specified in
                      clause (ii) of this Section 4(b) and Warrant Holder
                      does not achieve the [**]% Fair Share Threshold
                      specified in clause (iii) of this Section 4(b) for
                      the early exercisability of Warrants for the third
                      Measuring Period, Warrant Holder shall have the right
                      upon completion of the third Measuring Period and
                      thereafter to exercise Warrants for [**]% of the [**]%
                      portion of the Warrants that would have otherwise
                      become exercisable upon the Company's achieving the
                      $[**] million Net Revenue benchmark or Warrant
                      Holder's achieving the [**]% Fair Share Threshold for
                      such Measuring Period, if, during the entire term of
                      the third Measuring Period, Warrant Holder does not
                      voluntarily participate in any name-your-price
                      airline ticket service other than the Company's and
                      its affiliates' airline ticket services.

           (c)  Measuring Periods and Net Revenue.

                (i)   As used in this Warrant Agreement, the term
                      "Measuring Period" shall mean a 12-month period, with
                      the first such Measuring Period commencing on the
                      Date the Warrant Holder first provides tickets for
                      sale by the Company (the "First Ticket Date").
                      Subsequent Measuring Periods will expire on the
                      second, third, fourth and fifth anniversary of the
                      First Ticket Date, respectively, except that the
                      fifth Measuring Period shall end on the fifth (5th)
                      anniversary of the Issue Date.

                (ii)  As used in this Warrant Agreement, the term "Net
                      Revenue" shall mean the total ticket revenue received
                      by the Company from tickets sold for travel on the
                      Warrant Holder and its Code Share Partners, net of
                      federal excise and segment taxes, passenger facility
                      charges and related fees. The parties acknowledge
                      that credit card processing fees, and any processing
                      fees or similar fees charged by the Company to the
                      consumer in connection with the sale of a ticket
                      shall not be included in the calculation of Net
                      Revenue.. Attached hereto as Exhibit D is an example
                      of the calculation of Net Revenue.

                (iii) As used in this Warrant Agreement, the term "Fair
                      Share" shall mean Warrant Holder's domestic market
                      share calculated as a fraction, the numerator of
                      which shall be Warrant Holder's RPM's for U.S.
                      originating O&D's only, and the denominator of which
                      shall be the total RPM's for U.S. originating O&D's
                      only of all of the Company's participating airlines.

      5.   Exercise of Purchase Rights.

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

           (b)  Net Issue Exercise.  Notwithstanding any provisions herein
 to the contrary, if the fair market value of one share of the Company's
 Common Stock is greater than the Exercise Price (at the date of calculation
 as set forth below), in lieu of exercising the Warrants for cash, the
 Warrant Holder may elect to receive shares equal to the value (as
 determined below) of the Warrants (or portion thereof being canceled) by
 surrender of the Warrants at the principal office of the Company together
 with the duly executed Notice of Exercise in which event the Company shall
 issue to the Warrant Holder a number of shares of Common Stock computed
 using the following formula:  X=Y(A-B)/ A WHERE X= the number of shares of
 Common Stock to be issued to the Warrant Holder; Y= the number of shares of
 the Common Stock purchasable under the Warrants or, if only a portion of
 the Warrants is being exercised, the portion of the Warrants being canceled
 (at the date of such calculation); A= the fair market value of one share of
 the Company's Common Stock (at the date of such calculation); and B=
 Exercise Price (at the date of such calculation).  For purposes of the
 above calculation, fair market value of one share of the Common Stock shall
 be equal to the closing trading price of the Company's Common Stock on the
 day immediately prior to the date the Notice of Exercise is tendered to the
 Company.

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

      7.   No Fractional Shares.  No fractional shares or scrip representing
 fractional shares shall be issued upon the exercise of the Warrant Holder's
 rights to purchase the Shares.

      8.   No Rights as Shareholder.  This Warrant Agreement does not
 entitle the Warrant Holder to any voting rights or other rights as a
 shareholder of the Company prior to the exercise of the Warrant Holder's
 rights to purchase the Shares as provided for herein.

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

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

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

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

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

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

           (e)  Other Changes.  If any change in the outstanding Common
 Stock of the Company or any other event occurs as to which the other
 provisions of this Section 10 are not strictly applicable or if strictly
 applicable, would not fairly protect the purchase rights of the Warrant
 Holder in accordance with such provisions, then the Board of Directors of
 the Company shall make an adjustment in the number of and class of shares
 available under the Warrants, the Exercise Price or the application of such
 provisions, so as to protect the purchase rights of the Warrant Holder.
 The adjustment shall be such as will give the Warrant Holder upon exercise
 for the same aggregate Exercise Price the total number, class and kind of
 shares or other property as the Warrant Holder would have owned had the
 Warrants been exercised prior to the event and had the Warrant Holder
 continued to hold such shares until after the event requiring adjustment.

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

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

      11.  Representations and Warranties of the Warrant Holder.

      The Warrant Holder hereby represents and warrants to the Company as

 performance by, or enforcement against, the Warrant Holder of this Warrant
 Agreement or the transactions contemplated hereby.

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

           (e)  Purchase for Own Account.  The Warrants issued to the
 Warrant Holder pursuant to this Warrant Agreement, and the Shares to be
 issued upon vesting and exercise thereof, are being or will be acquired for

 any state.

           (f)  Restricted Securities.  The Warrant Holder understands that
 the Warrants and the Shares issuable upon vesting and exercise of the
 Warrants, will not be registered at the time of their issuance under the
 Securities Act for the reason that the sale provided for in this Agreement
 is exempt pursuant to Section 4(2) of the Securities Act and that reliance
 of the Company on such exemption is predicated in part on such Warrant
 Holder's representations set forth herein.  The Warrant Holder represents

 receive answers from the Company concerning the terms and conditions of the
 Warrants, the business of the Company, and to obtain additional information
 to such Warrant Holder's satisfaction.

 Investor" within the meaning of Rule 501 of Regulation D under the
 Securities Act, as presently in effect.

      12.  Compliance with Securities Act; Transferability of Warrant or
 Shares of Common Stock.

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

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

           (b)  Exchange, Transfer, Assignment.  The Warrants cannot be
 exchanged, transferred or assigned otherwise than in accordance with
 applicable law. Upon compliance with applicable law and surrender of the
 Warrants to the Company with the Assignment Form annexed hereto as Exhibit
 B duly executed, and funds sufficient to pay any transfer tax, the Company
 shall, without charge, execute and deliver a new Warrant Agreement in the
 name of the heir, devisee or assignee named in such instrument of
 assignment and this Warrant Agreement shall promptly be canceled.  Subject
 to the terms hereof, the Warrants may be assigned in whole or in part.

      13.  Restricted Securities.  The Warrant Holder understands that the
 Warrants and the Shares issuable upon vesting and exercise of the Warrants,

[**]=Confidential Treatment requested for redacted portion



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

                      AIRLINE PARTICIPATION AGREEMENT


           THIS AGREEMENT (this "Agreement"), dated as of November 17, 1999,
 is by and between priceline.com Incorporated, a Delaware corporation
 ("Priceline"), and US Airways, Inc., a Delaware corporation ("US Airways").

                           PRELIMINARY STATEMENT

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

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

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

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


 I.   Delta Airlines Consent to US Airways participation:

      US Airways acknowledges Priceline's pre-existing agreement with Delta
      Air Lines, Inc. ("Delta") granting Delta the right to approve and/or
      limit additional airline participation in the Priceline Service.
      Priceline represents that it has obtained permission from Delta
      consenting to US Airways' ' participation in the Priceline Service
      upon the condition that Priceline limit US Airways' participation as
      provided in Section V of this Agreement.  Priceline acknowledges the
      desire and preference of US Airways to participate in the Priceline
      Service without restriction.  This Agreement in its entirety
      supersedes any previous participation agreement between Priceline and
      USAirways.

 II.  Ticket Restrictions and Related Matters

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

      All tickets issued by Priceline for carriage on US Airways (each, a
      "Priceline Ticket") shall be subject to the following restrictions
      (the "Restrictions"):

           Except as otherwise provided in this Agreement, all Priceline
      Tickets will be non-refundable, non-endorsable and non-changeable;

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

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

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

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

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

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

           Except as otherwise provided herein, in any seven-day calendar
      period, a Priceline customer shall be limited to making one offer
      price for airline ticket(s) for a Trip.  A "Trip" is defined as travel
      between the same airports on the same dates of travel.  A Priceline
      customer may, within a seven-calendar day period, make an offer for
      travel in a different airport pair or on different dates of travel.
      Priceline will not knowingly sell a ticket to a Priceline customer in
      response to a second (or subsequent) offer for a Trip within a seven
      calendar day period; provided, that Priceline may sell a ticket in
      connection with a second offer if the Priceline customer (i) accepts,
      as part of the second offer, (x) a travel package which includes a
      hotel or rental car offer, or (y) a product or service co-marketed by
      Priceline such as a credit card or long distance telephone service or
      other co-marketing program.

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

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

           All Priceline Tickets issued for carriage on US Airways shall be
      subject to the published conditions of carriage and the fare rules of
      US Airways, to the extent such conditions and fare rules are

      consistent with the Restrictions.  US Airways will honor all Priceline
      Tickets issued for travel on US Airways in accordance with the
      Restrictions and other rules and conditions established by US Airways
      for Priceline Tickets.


 III. Priceline Ticket Reservations, Bookings, Payment and Fulfillment

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

           2.   Subject to Article VI, Priceline will determine the price at
 which tickets are sold based on customer offers received through the
 Priceline Service.  Priceline shall not advertise prices or fares offered
 by any carrier that are below US Airways' published or unpublished fares.

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

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

           5.   In all Priceline Ticket transactions, Priceline will be the
 merchant of record and will pay all associated merchant credit card fees.
 All Priceline tickets sold on US Airways will be settled through US Airways
 Reporting Corporation ("ARC").

           6.   All tickets of US Airways issued through the Priceline
 Service will be issued by Priceline using Agency ARC:  07-50854-6.  In
 collecting payment for Priceline Tickets, Priceline will act as the agent
 of US Airways pursuant to Agent's ARC Agent Reporting Agreement with ARC.

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

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

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

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

           11.  US Airways agrees to test special fares in Priceline at [**]%
 to [**]% off any retail fare available for sale by the travel agency
 community.  However, US Airways retains the right to increase, decrease or
 eliminate the discount in any and all markets throughout the life of this
 Agreement.  In addition, US Airways will from time to time, and at its own
 discretion, provide Priceline with discounts and special fares that are not
 generally available through traditional retail distribution channels.

           12.  Priceline may use fares provided to the Priceline Service
 for promotional purposes on specific terms as agreed to by US Airways as
 long as the actual fares offered are not made public and US Airways is not
 featured more prominently or frequently than any other participant.  In
 addition, US Airways will from time to time, at its discretion, provide
 Priceline with specific offers to promote customer use of the Priceline
 Service.

           When notifying passengers that their bids were unsuccessful
 through the Priceline Service, Priceline will offer such passengers a "hot
 link" to US Airways' branded reservation home page (USAirways.com) as an
 alternative source for air fares and tickets.  Priceline agrees to present
 US Airways, among potential multiple airline links, in an unbiased manner.
 Priceline will work to offer this enhancement to its current service in as
 timely a manner as possible not to exceed 180 days after the date of this
 Agreement.


 IV.  Priceline Ticket Allocation Methodology; Participating Carriers

           1.   Priceline has established an allocation methodology that
 determines when a participating airline will be given the first opportunity
 to fill a customer ticket request. First and second looks are allocated to
 participating carriers  on the basis of objective quality of service index
 ("QSI") criteria provided by Airline Planning Group, LLC ("APG").  The
 allocation system will apply this O&D QSI in the top 2500 domestic and top
 2500 international markets based on demanded revenue.  In smaller O & D
 markets, "looks" will be allocated on the basis of aggregate carrier system
 share.  Priceline will not give any carrier a structural first or second
 look advantage that is more favorable than that given to USAirways.

           2.   Priceline will allocate US Airways' "First Look" and "Second
 Look" opportunities based on US Airways' QSI share of carriers
 participating in Priceline.  USAirways' first Looks will be written at the
 highest qualifying US Airways fare provided to Priceline. In cases where
 either the first or second look carrier fails to fulfill any given offer,
 Priceline reserves the right to allocate traffic as it chooses.

           3.   During the term of this Agreement, if Priceline offers
 another airline terms of participation affecting sales of airline tickets,
 including but not limited to the offer of airline availability, prices or
 promotions, that are in the aggregate more favorable than those offered to
 US Airways hereunder, then Priceline will offer US Airways the same or
 equivalent benefit.  This provision does not apply to agreements entered
 between Priceline and another airline prior to US Airways' participation in
 Priceline.

           4.   Priceline will not make any changes to its allocation or
 other processing methodology that will reduce US Airways' revenue share of
 sales through Priceline over the term of this Agreement.  US Airways market
 share, however, may be affected by the participation of fewer or additional
 airlines on a pro rata basis.  At US Airways request, Priceline will supply
 substantiation that that its allocation or other processing methodologies
 comply with the terms of this Agreement.

           5.   Priceline will work in good faith with US Airways to assist
 it in achieving its objective for the Priceline Service within the context
 of the allocation system set forth above.  Priceline may work in good faith
 with other participating airlines in achieving their objectives for the
 Priceline Service within the context of the allocation system.


 V.   Restriction on US Airways Participation.

           1.   In the following markets, Priceline is contractually
 restricted by Delta, from issuing US Airways tickets within the Priceline
 Service:

           a.   To/from Atlanta except between ATL-CLT/PHL/PIT and any
      market to or from ATL not served by Delta or its commuter
      affiliate(s).

           b.   To/from BOS to any market served from BOS on a nonstop basis
      by Delta or its commuter affiliate(s) except between BOS-CLT/PHL/PIT

           c.   To/from LGA to any market served from LGA on a nonstop basis
      by Delta or its commuter affiliate(s) except between LGA-CLT/PHL/PIT

           2.   US Airways acknowledges the existence of the restrictions on
 its participation.


 VI.  Priceline Customer Service

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

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

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

           4.   The ticket Restrictions will apply to all tickets issued
 through the Priceline Service on US Airways.  US Airways may waive, at its
 own cost and expense, one or more of the Restrictions set forth in Article
 II, Sections 2(1)-(6) pursuant to a direct arrangement made by US Airways
 with the applicable customer holding a Priceline Ticket.  On an exception
 basis where necessary or appropriate to address an escalating customer
 service issue of any individual customer, Priceline may refund the price of
 a Priceline Ticket pursuant to the applicable customer. Priceline will
 report such refunds and cancellations to US Airways monthly.  In the event
 that such refunds exceed [**]% of gross ticket sales in any month, Priceline
 will implement such actions as are necessary to cause total refunds to be
 below [**]% of gross ticket sales in the following month.  If in any three
 month period, total refunds exceed [**]% of gross ticket sales, Priceline will
 be responsible for any refunds greater than [**]% of gross ticket sales.
 Priceline and US Airways will jointly develop any further guidelines on
 which such exception refunds will be governed.


 VII.   [**]

           1.   [**]

           2.   Priceline reserves the right to solely determine at what
 offer price customers may purchase an airline ticket through the Priceline
 Service.  However, Priceline will not agree with any airline to establish a
 minimum price in any O&D market.

           3.   Priceline will provide US Airways with participation rights
 in the Priceline Service as favorable as it provides to United Airlines and
 America Airlines, subject to restrictions in Article V.


 VIII.     Confidentiality

           1.   US Airways agrees to keep the terms of this agreement
 confidential until such time as Priceline has received formal notification
 from Delta Airlines validly consenting to US Airways' participation in the
 Priceline system.

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

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

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

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

           (3)  is necessary to comply with applicable law or the order or
      other legal process of any court, governmental or similar authority
      having jurisdiction over the recipient.  US Airways acknowledges that
      Priceline may be required to file this Agreement with the Securities
      and Exchange Commission ("SEC"), as required by federal securities
      laws, and that such filing shall not be deemed a violation of the
      provisions of this Article VIII.

           4.   Except as otherwise specifically provided in Section 2(c) of
 this Article VIII with respect to Priceline's filing requirements with the
 SEC, in the event that the recipient becomes legally compelled to disclose
 any such Confidential Information by any governmental body or court,
 recipient will provide the disclosing party with prompt notice so that the
 disclosing party may seek a protective order or other appropriate remedy
 and/or waive compliance (in writing) with the provisions hereof.  In the
 event that such protective order or other remedy is not obtained, or the
 disclosing party waives (in writing) compliance with the provisions hereof,
 recipient will furnish only that portion of such Confidential Material
 which is legally required and will exercise its reasonable business efforts
 to obtain appropriate assurance that confidential treatment will be
 accorded such Confidential Information.

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

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


 IX.  Proprietary Marks

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

 ECONOMIC ADVANTAGE, ARISING FROM THIS AGREEMENT OR ANY BREACH HEREOF.

           13.  THE PARTIES AGREE THAT IRREPARABLE DAMAGE WOULD OCCUR IN

                 Fares during such Measuring Period, Warrant Holder will earn
                 the right to exercise that number of Warrants for a portion
                 of the second [**] Shares, subject to adjustment as
                 provided in Section 10 hereof, equal to the product of (i)
                 [**] (subject to adjustment as provided in Section 10
                 hereof) multiplied by (ii) a fraction, the numerator of
                 which shall be the Net Revenue in excess of $[**] million sold
                 by the Company during such Measuring Period, and the
                 denominator of which shall be $[**] million.

           (iii) Net Revenue will be measured separately, not cumulatively, for
                 each measuring period. For example, if the Company has sold
                 Warrant Holder Net Fares of $[**] million during the first
                 Measuring Period, $[**] million during the second Measuring
                 Period, and $[**] million during the third Measuring Period,
                 then the Warrant Holder will earn the right to exercise
                 Warrants for [**] Shares upon completion of the first Measuring
                 Period, the right to exercise Warrants for [**] Shares ([**] x
                 [**]) upon completion of the second Measuring Period, and the
                 right to execise Warrants for [**] Shares ([**] x [**]) upon
                 completion of the third Measuring Period. For purposes of this
                 example, it is assumed that no adjustment pursuant to Section
                 10 hereof has occurred.

            (iv) Notwithstanding the Net Revenue benchmarks specified in clauses
                 (i) and (ii) of this Section 4(b) for the early exercisability
                 of Warrants, if, in any Measuring Period, the Company fails to
                 achieve the minimum Net Revenue from ticket sales for travel on
                 Warrant Holder and its Code Share Partners necessary to enable
                 Warrant Holder to exercise Warrants thereunder, then, effective
                 on the completion of such Measuring Period and thereafter,
                 Warrant Holder (i) shall have the right to exercise Warrants
                 for [**] Shares, subject to adjustment as provided in Section
                 10 hereof, if Warrant Holder's and its Code Share Partners'
                 percentage of the Aggregate Ticket Sales Revenues (as defined
                 in Section 4(c)) for U.S. originating O&D's for such Measuring
                 Period equals or exceeds [**]% of Warrant Holder's Fair Share
                 (as defined in Section 4(c) below), and (ii) shall have the
                 right to exercise Warrants for [**] Shares, if Warrant Holder's
                 and its Code Share Partners' percentage of the Aggregate Net
                 Ticket Sale Revenues for U.S. originating O&D's for such
                 Measuring Period equals or exceeds [**]% of Warrant Holder's
                 Fair Share. In the event that in any Measuring Period, the
                 Warrant Holder exceeds [**]% of its Fair Share but does not
                 reach [**]% of its Fair Share, then Warrant Holder will earn
                 the right to exercise that number of Warrants for a portion of
                 the second [**] Shares, subject to adjustment as provided in
                 Section 10 hereof, equal to the product of (i) [**] (subject to
                 adjustment as provided in Section 10 hereof) multiplied by (ii)
                 a fraction, the numerator of which shall be the Fair Share
                 percentage (expressed as a number and not a percentage) in
                 excess of [**]% achieved by the Warrant Holder and its Code
                 Share Partners during such Measuring Period, and the
                 denominator of which shall be [**]. Fair Share will be measured
                 separately, not cumulatively, for each Measuring Period. For
                 example, if the Warrant Holder achieves [**]% of its Fair Share
                 during the first Measuring Period, [**]% of its Fair Share
                 during second Measuring Period, and [**]% during the third
                 Measuring Period, then the Warrant Holder will earn the right
                 to exercise Warrants for [**] Shares upon completion of the
                 first Measuring Period, the right to exercise Warrants for [**]
                 Shares ([**] x [**]) upon completion of the second Measuring
                 Period, and the right to exercise Warrants for [**] Shares
                 ([**] x [**]) upon completion of the third Measuring Period.

            (c)   Measuring Periods; Fair Share; Aggregate Net Ticket Sale
Revenues.

            (i)  Each Measuring Period shall be a 12 month period, with the
                 first Measuring Period commencing on the date the Warrant
                 Holder first provides tickets for sale by the Company (the
                 "First Ticket Date") and ending on the first anniversary of
                 such date. Subsequent Measuring Periods will expire on the
                 second, third, fourth and fifth anniversary of the First
                 Ticket Date, respectively; provided that the last Measuring
                 Period will expire on the fifth anniversary of the Issue Date.

            (ii) As used in this Warrant Agreement, the term "Fair Share"
                 shall mean Warrant Holder's domestic market share calculated
                 as a fraction, the numerator of which shall be Warrant
                 Holder's RPM's for U.S. originating O&D's only, and the
                 denominator of which shall be the total RPM's for U.S.
                 originating O&D's only of all of the Company's participating
                 airlines. The forgoing calculation shall excluded in the
                 numerator and the denominator, O&D markets in which Warrant
                 Holder is restricted from providing service in the Company's
                 airline ticket service ("Restricted Markets").

           (iii) As used is this Warrant Agreement, the term "Aggregate Net
                 Ticket Sale Revenues" for any Measuring Period, shall mean,
                 the total amount paid by the Company to its participating
                 airlines, including Warrant Holder and its Code Share
                 Partners for airline tickets sold for US originating O&D's
                 (excluding O&D's for Restricted Markets) on all of the
                 Company's participating airlines, net of federal excise
                 taxes on such amounts, PFCs and related collections.

            (d) Warrant Holder's right to earn early exercise rights under
Section 4(b) is contingent upon Airline's NOT TAKING AN EQUITY POSITION OF
ANY NATURE WHATSOEVER, including, without limitation, common stock,
preferred stock, warrants, options, or debt, in any other operator or
affiliate thereof (an "Operator") of a "demand collection system" for sale
of airline tickets over the Internet. For purposes of this Section 4(d),
"demand collection system" is narrowly defined as an airline ticket service
that (i) enables a consumer to name the price the consumer is willing to
pay for one or more airline tickets prior to the Seller's display of the
price actually paid by the consumer, (ii) enables the seller to bind the
consumer to the consumer's offer price upon the seller's acceptance of the
consumer's offer, and (iii) does not permit the consumer to specify the
exact airline on which the consumer is willing to fly. In order for Warrant
Holder to be entitled to earn the early exercise rights specified in
Section 4(b)(i) and 4(b)(ii), as the case may be, Warrant Holder must not
at any time between the date hereof and the date it earns such early
exercise rights, take an equity position of any nature whatsoever in any
Operator of a "demand collection system" other than the Company's for the
sale of airline tickets over the Internet. For example, if in the first
Measuring Period, the Company achieves Net Revenues that would entitle the
Warrant Holder to exercise Warrants for the first 750,000 Shares, the
Warrant Holder will be entitled to exercise such Warrants at all times
after the completion of such Measuring Period so long as the Warrant Holder
at all times from the date hereof though the date it earned such early
exercise rights had not taken an equity position in any other Operator of a
"demand collection system" for the sale of airline tickets over the
Internet. If at any time from the date hereof prior to the fifth 5th
anniversary of the Grant Date, the Warrant Holder takes an equity position
in an Operator of another "demand collection system" for the sale of
airline tickets over the Internet, the Warrant Holder's right to earn early
exercise rights will terminate and be of no further force or effect with
respect to Warrants for which Warrant Holder did not earn early exercise
rights prior to the date of Warrant Holder's taking such equity position,
and such Warrants will become exercisable on the fifth 5th anniversary of
the Grant Date.

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

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

     7.   No Fractional Shares. No fractional shares or scrip representing
          fractional shares shall be issued upon the exercise of the
          Warrant Holder's rights to purchase the Shares.

     8.   No Rights as Shareholder. This Warrant Agreement does not entitle
          the Warrant Holder to any voting rights or other rights as a
          shareholder of the Company prior to the exercise of the Warrant
          Holder's rights to purchase the Shares as provided for herein.

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

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

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

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

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

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

            (e) Other Changes. If any change in the outstanding Common
Stock of the Company or any other event occurs as to which the other
provisions of this Section 10 are not strictly applicable or if strictly
applicable, would not fairly protect the purchase rights of the Warrant
Holder in accordance with such provisions, then the Board of Directors of
the Company shall make an adjustment in the number of and class of shares
available under the Warrants, the Exercise Price or the application of such
provisions, so as to protect the purchase rights of the Warrant Holder. The
adjustment shall be such as will give the Warrant Holder upon exercise for
the same aggregate Exercise Price the total number, class and kind of
shares or other property as the Warrant Holder would have owned had the
Warrants been exercised prior to the event and had the Warrant Holder
continued to hold such shares until after the event requiring adjustment.

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

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

      11. Representations and Warranties of the Warrant Holder.

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

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

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

            (c) Governmental Authorization; Third Party Consents. No
approval, consent, compliance, exemption or authorization of any
governmental authority or agency, or of any other person or entity, is
necessary or required in connection with the execution, delivery or
performance by, or enforcement against, the Warrant Holder of this Warrant
Agreement or the transactions contemplated hereby.

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

            (e) Purchase for Own Account. The Warrants issued to the
Warrant Holder pursuant to this Warrant Agreement, and the Shares to be
issued upon vesting and exercise thereof, are being or will be acquired for
the Warrant Holder's own account and with no intention of distributing or
reselling such securities or any part thereof in any transaction that would
be in violation of the securities laws of the United States of America, or
any state.

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

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

      12.   Compliance with Securities Act; Transferability of Warrant or
            Shares of Common Stock.

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

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

            (b) Exchange, Transfer, Assignment or Loss of Warrants. The
Warrants cannot be exchanged, transferred or assigned otherwise than in
accordance with applicable law. Upon compliance with applicable law and
surrender of the Warrants to the Company with the Assignment Form annexed
hereto as Exhibit B duly executed, and funds sufficient to pay any transfer
tax, the Company shall, without charge, execute and deliver a new Warrant
Agreement in the name of the heir, devisee or assignee named in such
instrument of assignment and this Warrant Agreement shall promptly be
canceled. In the event that Warrant Holder sells, assigns or transfers this
Warrant Agreement and the Warrants represented hereby, the early exercise
rights and restrictions set forth in Section 4(b), 4(c), and 4(d) shall
survive, provided, that the determination, at any time and from time to
time, of whether the new Warrant Holder shall be entitled to early exercise
rights under such sections will be made on whether US Airways, Inc. has
achieved and/or does achieve the performance targets specified in Sections
4(b) and 4(c) and has and continues even after the assignment to be in
compliance with the restrictions set forth in Section 4(d). Accordingly, if
at any time, before or after a sale, assignment or transfer of this Warrant
Agreement and the Warrants represented hereby, US Airways, Inc. (if it had
continued to the hold Warrants represented hereby) would not be entitle to
early exercise rights, the assignee hereof will not be entitle to the early
exercise rights.

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

     14.  Registration Rights. The Company will use its best efforts to
          cause the Warrant Holder to become a party to that certain
          Amended Registration Rights Agreement, dated as of December 8,
          1998, by and among the Company and the stockholders of the
          Company named therein, on such terms and conditions as may be
          reasonably acceptable to the Company, the Warrant Holder and the
          other stockholders party to such Amended Registration Rights
          Agreement.

     15.  Miscellaneous.

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

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

               FILED WITH THE SECURITIES AND EXCHANGE COMMISSION.

                      AIRLINE PARTICIPATION AGREEMENT


      THIS AGREEMENT (this "Agreement"), dated as of November 17, 1999, is
 by and between priceline.com Incorporated, a Delaware corporation with an
 address at Five High Ridge Park, Stamford, Connecticut 06905 ("Priceline"),
 and American Airlines, Inc., a Delaware corporation, whose principal place
 of business is set forth in the notice provision of this Agreement
 ("Airline").

                           Preliminary Statement

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

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

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

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


 I.   Ticket Restrictions and Related Matters

      1.   Airline shall make available to Priceline unpublished fares (the
           number an pricing of which determined by Airline in its sole
           discretion), for O&Ds (selected by Airline in its sole
           discretion) for a minimum period of l year, effective from the
           date that Priceline issues the first ticket on such fares. Such
           fares may be either, in Airline's sole discretion, "Special Net
           Fares" that provide fixed price levels with rules and
           availability classes specific to Priceline; or these fares may be
           "Netted Retail Fare" that are constructed by applying a specific
           discount, if any, to published retail fares. If Netted Retail
           Fares are used, Airline agrees to provide reasonable advance
           purchase rule waivers so that such fares can be used to issue
           Priceline Tickets (defined below).  All unpublished fares
           provided to Priceline must be issued in accordance with rules and
           restrictions provided to Priceline by Airline from time to time.
           By way of example only, unpublished fares on certain O&D's may
           require specific routings or be flight/day specific. At all times
           during the term of this Agreement, Airline will exclusively
           control and determine the unpublished fares, the O&Ds, the rules
           and restrictions, and the levels of inventory provided to
           Priceline by Airline.

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

           (a)  Except as otherwise provided in Section IV.4 hereof, all
                Priceline Tickets will be nonrefundable, nonendorsable and
                nonchangeable;

           (b)  All travel will be roundtrip with no stopovers or openjaw
                travel permitted, with no upgrades permitted and no seat
                assignments prior to date of departure;

           (c)  Frequent Flyer mileage and upgrades will not be permitted;
                provided, Airline may offer such benefits at its option;

           (d)  Priceline customers must agree to (i) make up to one stop or
                connection on both their departing and return flights on any
                routing, (ii) accept a ticket on any carrier participating
                in the Priceline Service (each , a "Participating Carrier"),
                and (iii) travel on any flight on the specified date of
                travel (x) for domestic U.S. flights, departing during the 6
                a.m.  10p.m. time period (or other base period that may be
                identified) unless the customer has specified a request to
                include flights departing outside those periods, and (y) for
                international flights, at any time (i.e., 12:0 l a.m. to
                11:59 p.m.);

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

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

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

           (h)  Except as otherwise provided herein, in any seven (7) day
                calendar period, a Priceline customer shall be limited to
                making one (1) offer price for airline ticket(s) for a Trip. A
                "Trip" is defined as travel between the same airports on the
                same dates of travel. A Priceline customer may, within a seven
                calendar day period, make an offer for travel in a different
                airport pair, on different dates of travel or accept off-peak
                travel on nonjet service. Priceline will not sell a ticket to a
                Priceline customer in response to a second (or subsequent)
                offer for a Trip within a seven calendar day period; provided,
                that Priceline may sell a ticket in connection with a one time
                second offer if the Priceline customer (i) raises the offer by
                a minimum of [**] and (ii) accepts, as part of the second
                offer, (x) a travel package which includes a hotel or rental
                car offer, or (y) a product or service co- marketed by
                Priceline such as a credit card or long distance telephone
                service or other co-marketing program

      3.   Airline may include, in addition to the Restrictions, other fare
           rules and conditions for Priceline Tickets issued on Airline.
           All Priceline Tickets issued for carriage on Airline shall be
           subject to the published conditions of carriage and the fare
           rules of Airline, to the extent such conditions and fare rules
           are not inconsistent with the Restrictions.  Airline will honor
           all Priceline Tickets issued for travel on Airline in accordance
           with the Restrictions and other rules and conditions established
           by Airline for Priceline Tickets.


 II.  Priceline Ticket Reservations., Bookings, Payment and Fulfillment

      1.   Airline will file unpublished fares and rules for Priceline
           Tickets selected by Airline with the computer reservation system
           ("CRS") used by Priceline.  Additionally, Priceline will
           cooperate with Airline to identify and work toward the most
           efficient system for the filing of fares for use by Priceline in
           the operation of its air travel service with Airline, including
           direct settlement through Airline's internal reservation system.

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

      3.   All unpublished fares made available by Airline for sale through
           the Priceline Service shall not be commissionable and shall be
           inclusive, where applicable, of the applicable domestic federal
           transportation excise tax contained in Section 4261(a) of the
           Internal Revenue Code. All such unpublished fares shall be
           exclusive of any Ticket Taxes, which, when applicable, must be
           added to the fare amount and paid by Priceline to Airline
           including the domestic federal segment taxes contained in Section
           4261(b) of the Internal Revenue Code.  The term "Ticket Taxes" is
           defined in Section VII.4. of this Agreement.

      4.   In all Priceline Ticket transactions, Priceline will be the
           merchant of record and will pay and be responsible for all
           associated merchant charges and expenses including, without
           limitation, credit card fees, and will assume the risk of
           nonpayment by the customers and/or the credit card companies. All
           Priceline tickets sold on Airline will be settled through Airline
           Reporting Corporation ("ARC").

      5.   All tickets of Airline issued through the Priceline Service will
           be issued by Priceline using Agency ARC: 07508546. In collecting
           payment for Priceline Tickets, Priceline will act as the agent of
           Airline pursuant to Agent's ARC Agent Reporting Agreement with
           ARC.

      6.   Unless otherwise directed by a Priceline customer, all Priceline
           Tickets issued on Airline will be issued electronically.
           Priceline will encourage its customers to accept electronic
           ticketing for all Priceline Ticket requests by imposing an
           additional charge for the issuance of paper tickets and
           maintaining the issuance of electronic tickets as the default
           option on the Priceline Service.  After issuance of electronic
           tickets, Priceline will promptly forward to the customer a
           receipt of purchase and standard conditions.

      7.   Subject to the provisions of Paragraph  II.5 above, all Priceline
           paper tickets for carriage on Airline will be issued by Priceline
           on standard ARC traffic documents and will be validated with
           Airline's validation in accordance with ARC requirements. The
           passenger coupon will show "bulk" for the fare amount and will
           include all additional collections noted in Paragraph 11.3 above.
           The auditor's coupon will show the Airline's unpublished fare
           authorized for Priceline.

      8.   At the request of Airline, Priceline will incorporate into the
           Priceline Service, on commercially negotiated terms, a "hot link"
           to the designated Internet site of Airline; provided, however,
           that Priceline will have a reasonable period of time following
           any such request to accomplish any system changes, additions or
           enhancements necessary or appropriate for the inclusion of any
           such hot link.

 III. Priceline Ticket Allocation Methodology

      All Participating Carriers will be given the first opportunity to fill
      a customer ticket request based on a formula which allocates such
      requests in proportion to the aggregate domestic or international
      market share (as applicable) of each Participating Carrier for each
      O&D requested.  If a Participating Carrier fails to respond to a
      ticket request on its designated first look, then Priceline will
      allocate the request through a second round of preferred looks, which
      will be allocated in proportion to the aggregate domestic or
      international market shares (as applicable) of all remaining
      Participating Carriers for each O&D requested (but excluding the
      Participating Carrier that failed to fulfill the ticket request on the
      first look).  In the event that the Participating Carrier with the
      first look allocation is unable to satisfy the offer, and the
      Participating Carrier with the second look allocation is unable to
      satisfy the offer, Priceline will allocate "subsequent looks" in its
      sole discretion to satisfy a customer's offer.

 IV.  Priceline Customer Service

      1.   Priceline will provide twenty-four (24) hour customer support
           services to all Priceline customers through a toll-free number at
           the customer support center designated by Priceline from time to
           time. The customer support center will be adequately staffed with
           personnel trained to take Priceline Ticket requests by phone and
           respond to all customer inquiries for related service and
           support. Priceline will use commercially reasonable efforts to
           ensure that its customer service representatives provide quality
           customer service and support to Priceline customers in a prompt,
           reliable and courteous manner.

      2.   The ticket Restrictions will apply to all tickets issued through
           the Priceline Service on Airline. Airline may waive, at its own
           cost and expense, one or more of the Restrictions set forth in
           Sections I.2 (a)(f) pursuant to a direct arrangement made by
           Airline with the applicable customer holding a Priceline Ticket.
           On an exception basis where necessary or appropriate to address
           an escalating customer service issue of any individual customer,
           Priceline may refund the price of a Priceline Ticket applicable
           to such customer.  In the event that such refunds exceed [**]% of
           Priceline Ticket gross ticket sales in any month, Priceline will
           implement such actions as are necessary to cause total refunds to
           be below [**]% of Priceline Ticket gross ticket sales in the
           following month.  If in any three month period, total refunds
           exceed [**]% of Priceline Ticket gross ticket sales, Priceline will
           be responsible for any refunds greater than [**]% of Priceline
           Ticket gross ticket sales. At Airlines' request, Priceline shall
           provide Airline with a monthly report detailing the number and
           amount of refunded Priceline Tickets involving air transportation
           services on Airline.  Priceline and Airline will jointly develop
           additional the guidelines upon which such exception refunds will
           be governed.


 V.   Confidentiality

      1.   Priceline and Airline will each hold in confidence and, without
           the prior written consent of the other, will not reproduce,
           distribute, transmit, transfer or disclose, directly or
           indirectly, in any form, by any means or for any purpose, any
           Confidential Information of the other party. As used herein, the
           term "Confidential Information" shall mean this Agreement and its
           subject matter, and proprietary information that is provided to
           or obtained from one party to the other party including any

           from not being generally known to, and not generally
           ascertainable by proper means by, other persons, including the
           unpublished fares provided by Airline to Priceline pursuant to
           this Agreement. The recipient of Confidential Information may
           only disclose such information to its employees, attorneys and
           accountants on a need-to-know basis and provided each is aware of
           this provision and agrees to comply with its terms.

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

           (a)  as a result of a disclosure by the recipient, or its
                directors ,officers, employees, agents or advisors;

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

           (c)  is necessary to comply with applicable law or the order of
                other legal process of any court or similar governmental
                authority having jurisdiction over the recipient; provided,
                that to the extent reasonably practicable, the recipient
                shall deliver any such order or legal process to the other
                party prior to complying therewith to enable the other party
                to seek a protective order or other remedy to protect it's
                the disclosure of its confidential information. Both parties
                hereto acknowledges that the other party  may be required to
                file this Agreement with the Securities and Exchange
                Commission ("SEC"), as required by federal securities laws,
                and that such filing shall not be deemed a violation of the
                provisions of this Article V; or

           (d)  was in the possession of the recipient party prior to the
                date of disclosure by the other party, as shown by written
                records of the recipient party

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

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

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

      6.   During the term of this Agreement neither Priceline nor Airline
           shall use the other party's trademarks, trade names, service
           marks, logos, emblems, symbols or other brand identifiers in
           advertising or marketing materials, unless it has obtained the
           prior written approval of the other party. The consent required
           by this Paragraph V.6. shall extend to the content of the
           specific advertising or marketing items as well as the placement
           and prominence of the applicable trademark, trade name, service
           mark, logo, emblem, symbol or other brand identifier of the other
           party.  Priceline or Airline, as applicable, shall cause the
           withholding, discontinuance, recall or cancellation, as
           appropriate, of any advertising or promotional material not
           approved in writing by the other party, that differs
           significantly from that approved by the other party, or that is
           put to a use or used in a media not approved by the other party.

      7.   Priceline will not disclose (including without limitation by
           sale) to any third party information specific to a customer's
           usage of Airline obtained through the Priceline Service.

      8.   During the term of the Agreement, and for a period of one year,
           thereafter, Airline agrees not to make any remarks to the public
           about Priceline or the Priceline Service that is intended to be
           negative or disparaging, other than in connection with any
           litigation between the parties or otherwise as required by law.

      3.   Priceline will indemnify, defend and hold harmless Airline, its

           property or bodily injury, on an after-tax basis, to the extent
           caused by or related to (i) Priceline's breach of this Agreement
           or the ARC Agent Reporting Agreement, (ii) any inaccuracy in any
           of Priceline's representations or warranties set forth in

           requirements of Section 7275 of the Internal Revenue Code and

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

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

      8.   Priceline agrees to notify Airline promptly, in writing, in the
           event there is a change of control in the ownership of Priceline.
           For purposes of this Agreement, a "change of  control" with
           respect to a party means (i) the acquisition by any other person
           or group (within the meaning of Section 13(d)(3) of the
           Securities Exchange Act (except an employee group of such party,
           any of its subsidiaries or a company of such party)), of the
           beneficial ownership securities representing 20% or more of the
           combined voting power of the securities entitled to vote
           generally in the election of the board of directors of such
           party, or (ii) the sale, mortgage, lease or other transfer of
           assets or earning power constituting more than 50% of the assets
           or earning power of such party (other than ordinary course
           financing); PROVIDED that in no event shall a change of control
           be defined to include (i) the formation by a party of a holding
           company or (ii) an intra-corporate transaction with a company
           under common control with a party.  Upon the occurrence of a
           change of control of a party, the other party may terminate this
           Agreement on thirty (30) days prior written notice.

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

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

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

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

      13.  It is expressly acknowledged that this Agreement is not
           conditioned in any way upon Priceline's  choice of, or use of,
           any particular computer reservation system.

      14.  Unless otherwise expressly provided, the remedies provided by
           this Agreement are not intended to be exclusive.  Each shall be
           cumulative and shall be in addition to all other remedies
           available to either party under this Agreement, at law or in
           equity.

      15.  This Agreement may be executed in counterparts, each of which
           shall be deemed an original, and together, shall constitute one
           and the same instrument.  Execution may be effected by delivery
           of facsimiles of signature pages (and the shall follow such
           delivery by prompt delivery of originals of such pages).


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

                      Warrants for [**]% of such Shares shall not accrue
                      unless and until the Company has, on an aggregated

                (iii) Notwithstanding the Net Revenue benchmarks specified
                      in clauses (i) and (ii) of this Section 4(b) for the
                      early exercisability of Warrants, if, in any
                      Measuring Period, the Company fails to achieve the
                      minimum Net Revenues from ticket sales for travel on
                      Warrant Holder and its Code Share Partners necessary
                      to enable Warrant Holder to exercise Warrants for the
                      [**]% or [**]% portion of Shares that would otherwise
                      become exercisable if such benchmarks were achieved
                      during such Measuring Period, then, effective on the
                      last day of such Measuring Period and thereafter,
                      Warrant Holder (i) shall have the right to exercise
                      Warrants for the [**]% portion of Warrants that would
                      otherwise become exercisable upon achieving the
                      corresponding Net Revenue benchmark for such
                      Measuring Period, if Warrant Holders and its Code
                      Share Partners' percentage of the aggregate of all
                      ticket sale revenues (calculated using the same
                      methodology used to calculate Net Revenue hereunder)
                      received by the Company for U.S. originating O&D's
                      for such Measuring Period equals or exceeds [**]% of
                      Warrant Holder's Fair Share (as defined in Section
                      4(c) below)(the "[**]% Fair Share Threshold"), and (ii)
                      shall have the right to exercise Warrants for the [**]%
                      portion of Warrants that would otherwise become
                      exercisable upon achieving the corresponding Net
                      Revenue benchmark for such Measuring Period, if
                      Warrant Holder's and its Code Share Partners'
                      percentage of the aggregate of all ticket sale
                      revenues received by the Company for U.S. originating
                      O&D's for such Measuring Period equals or exceeds
                      [**]% of Warrant Holder's Fair Share (the "[**]% Fair
                      Share Threshold"). For purposes of determining
                      whether Warrant Holder achieves the [**]% Fair Share
                      Threshold and/or the [**]% Fair Share Threshold for
                      the first, and only the first, Measuring Period, the
                      parties shall calculate Warrant Holder's and its Code
                      Share Partners' percentage of the Company's ticket
                      sale revenues for U.S. originating O&D's for such
                      period based on either (i) their percentage of the
                      aggregate of all ticket sale revenues received by the
                      Company for ticket sales for U.S. originating O&D's
                      during the entire first Measuring Period, or (ii)
                      their percentage of the aggregate of all ticket sale
                      revenues received by the Company for ticket sales for
                      U.S. originating O&D's during the final six (6)
                      months of the First Measuring Period, whichever is
                      more favorable for the Warrant Holder.

                (iv)  In the event that the Company does not achieve the
                      $[**] million Net Revenue benchmark specified in
                      clauses (i) of this Section 4(b) and Warrant Holder
                      does not achieve the [**]% Fair Share Threshold
                      specified in clause (iii) of this Section 4(b) for
                      the early exercisability of Warrants for the first
                      Measuring Period, Warrant Holder shall have the right
                      upon completion of the first Measuring Period and
                      thereafter to exercise Warrants for the [**]% portion
                      of Warrants that would otherwise become exercisable
                      upon the Company's achieving the $[**] million Net
                      Revenue benchmark or Warrant Holder's achieving the
                      [**]% Fair Share Threshold for such Measuring Period,
                      if, during the entire term of the first Measuring
                      Period, Warrant Holder does not voluntarily
                      participate in any name- your-price airline ticket
                      service other than (i) the Company's and its
                      affiliates' airline ticket services and (ii) any
                      other name-your price airline ticket service with
                      which Warrant Holder was discussing participation
                      prior to the date of execution this agreement.

                (v)   In the event that the Company does not achieve the
                      $[**] million Net Revenue benchmark specified in
                      clause (ii) of this Section 4(b) and Warrant Holder
                      does not achieve the [**]% Fair Share Threshold
                      specified in clause (iii) of this Section 4(b) for
                      the early exercisability of Warrants for the second
                      Measuring Period, Warrant Holder shall have the right
                      upon completion of the second Measuring Period and
                      thereafter to exercise Warrants for [**]% of the [**]%
                      portion of the Warrants that would have otherwise
                      become exercisable upon the Company's achieving the
                      $[**] million Net Revenue benchmark or Warrant
                      Holder's achieving the [**]% Fair Share Threshold for
                      such Measuring Period, if, during the entire term of
                      the second Measuring Period, Warrant Holder does not
                      voluntarily participate in any name-your-price
                      airline ticket service other than (i) the Company's
                      and its affiliates' airline ticket services and (ii)
                      any other name-your price airline ticket service with
                      which Warrant Holder was discussing participation
                      prior to the date of execution this agreement.

                (vi)  In the event that the Company does not achieve the
                      $[**] million Net Revenue benchmark specified in
                      clause (ii) of this Section 4(b) and Warrant Holder
                      does not achieve the [**]% Fair Share Threshold
                      specified in clause (iii) of this Section 4(b) for

                (i)   As used in this Warrant Agreement, the term
                      "Measuring Period" shall mean a 12-month period, with
                      the first such Measuring Period commencing on the
                      Date the Warrant Holder first provides tickets for
                      sale by the Company (the "First Ticket Date").
                      Subsequent Measuring Periods will expire on the
                      second, third, fourth and fifth anniversary of the
                      First Ticket Date, respectively, except that the
                      fifth Measuring Period shall end on the fifth (5th)
                      anniversary of the Issue Date.

                (ii)  As used in this Warrant Agreement, the term "Net
                      Revenue" shall mean the total ticket revenue received

                      federal excise and segment taxes, passenger facility
                      charges and related fees. The parties acknowledge
                      that credit card processing fees, and any processing
                      fees or similar fees charged by the Company to the
                      consumer in connection with the sale of a ticket
                      shall not be included in the calculation of Net
                      Revenue.

                (iii) As used in this Warrant Agreement, the term "Fair
                      Share" shall mean Warrant Holder's domestic market
                      share calculated as a fraction, the numerator of
                      which shall be Warrant Holder's RPM's for U.S.
                      originating O&D's only, and the denominator of which

                      only of all of the Company's participating airlines.

      5.   Exercise of Purchase Rights.

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

           (b)  Net Issue Exercise.  Notwithstanding any provisions herein
 to the contrary, if the fair market value of one share of the Company's
 Common Stock is greater than the Exercise Price (at the date of calculation
 as set forth below), in lieu of exercising the Warrants for cash, the
 Warrant Holder may elect to receive shares equal to the value (as
 determined below) of the Warrants (or portion thereof being canceled) by
 surrender of the Warrants at the principal office of the Company together
 with the duly executed Notice of Exercise in which event the Company shall
 issue to the Warrant Holder a number of shares of Common Stock computed
 using the following formula:  X=Y(A-B)/ A WHERE X= the number of shares of
 Common Stock to be issued to the Warrant Holder; Y= the number of shares of
 the Common Stock purchasable under the Warrants or, if only a portion of
 the Warrants is being exercised, the portion of the Warrants being canceled
 (at the date of such calculation); A= the fair market value of one share of
 the Company's Common Stock (at the date of such calculation); and B=
 Exercise Price (at the date of such calculation).  For purposes of the
 above calculation, fair market value of one share of the Common Stock shall
 be equal to the closing trading price of the Company's Common Stock on the
 day immediately prior to the date the Notice of Exercise is tendered to the
 Company.

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

      7.   No Fractional Shares.  No fractional shares or scrip representing
 fractional shares shall be issued upon the exercise of the Warrant Holder's
 rights to purchase the Shares.

      8.   No Rights as Shareholder.  This Warrant Agreement does not
 entitle the Warrant Holder to any voting rights or other rights as a
 shareholder of the Company prior to the exercise of the Warrant Holder's
 rights to purchase the Shares as provided for herein.

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

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

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

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

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

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

           (e)  Other Changes.  If any change in the outstanding Common
 Stock of the Company or any other event occurs as to which the other
 provisions of this Section 10 are not strictly applicable or if strictly
 applicable, would not fairly protect the purchase rights of the Warrant
 Holder in accordance with such provisions, then the Board of Directors of
 the Company shall make an adjustment in the number of and class of shares
 available under the Warrants, the Exercise Price or the application of such
 provisions, so as to protect the purchase rights of the Warrant Holder.
 The adjustment shall be such as will give the Warrant Holder upon exercise
 for the same aggregate Exercise Price the total number, class and kind of
 shares or other property as the Warrant Holder would have owned had the
 Warrants been exercised prior to the event and had the Warrant Holder
 continued to hold such shares until after the event requiring adjustment.

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

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

 to be issued upon exercise of the Warrants, are being acquired for

 assignment and this Warrant Agreement shall promptly be canceled.  Subject
 to the terms hereof, the Warrants may be assigned in whole or in part.

      13.  Restricted Securities.  The Warrant Holder understands that the
 Warrants and the Shares issuable upon vesting and exercise of the Warrants,

 of the warrant Holder set forth herein.  The Warrant Holder represents that
 it is experienced in evaluating companies such as the Company, has such
 knowledge and experience in financial and business matters as to be capable
 of evaluating the merits and risks of its investment and has the ability to
 suffer the total loss of the investment.  The Warrant Holder further
 represents that it has had the opportunity to ask questions of and receive

                        Measuring Period for travel on the Warrant Holder and

                        its Code Share Partners, and (ii) the right to exercise
                        Warrants for [**]% of such Shares shall not accrue
                        unless and until the Company has, on an aggregated basis
                        during the applicable Measuring Period, received at
                        least $[**] million of Net Revenues from tickets sold

                        Holder and its Code Share Partners.

                  (iii) Notwithstanding the Net Revenue benchmarks specified in
                        clauses (i) and (ii) of this Section 4(b) for the early
                        exercisability of Warrants, if, in any Measuring Period,
                        the Company fails to achieve the minimum Net Revenues
                        from ticket sales for travel on Warrant Holder and its
                        Code Share Partners necessary to enable Warrant Holder
                        to exercise Warrants for the [**]% or [**]% portion of
                        Shares that would otherwise become exercisable if such
                        benchmarks were achieved during such Measuring Period,
                        then, effective on the last day of such Measuring Period
                        and thereafter, Warrant Holder (i) shall have the right
                        to exercise Warrants for the [**]% portion of Warrants
                        that would otherwise become exercisable upon achieving
                        the corresponding Net Revenue benchmark for such
                        Measuring Period, if Warrant Holders and its Code Share
                        Partners' percentage of the aggregate of all ticket sale
                        revenues (calculated using the same methodology used to
                        calculate Net Revenue hereunder) received by the Company
                        for U.S. originating O&D's for such Measuring Period
                        equals or exceeds [**]% of Warrant Holder's Fair Share
                        (as defined in Section 4(c) below) (the "[**]% Fair
                        Share Threshold"), and (ii) shall have the right to
                        exercise Warrants for the [**]% portion of Warrants that
                        would otherwise become exercisable upon achieving the
                        corresponding Net Revenue benchmark for such Measuring
                        Period, if Warrant Holder's and its Code Share Partners'
                        percentage of the aggregate of all ticket sale revenues
                        received by the Company for U.S. originating O&D's for
                        such Measuring Period equals or exceeds [**]% of Warrant
                        Holder's Fair Share (the "[**]% Fair Share Threshold").

                  (iv)  In the event that the Company does not achieve the
                        $[**] million Net Revenue benchmark specified in
                        clauses (i) of this Section 4(b) and Warrant Holder does
                        not achieve the [**]% Fair Share Threshold specified in
                        clause (iii) of this Section 4(b) for the early
                        exercisability of Warrants for the first Measuring
                        Period, Warrant Holder shall have the right upon
                        completion of the first Measuring Period and thereafter
                        to exercise Warrants for the [**]% portion of Warrants
                        that would otherwise become exercisable upon the
                        Company's achieving the $[**] million Net Revenue
                        benchmark or Warrant Holder's achieving the [**]% Fair
                        Share Threshold for such Measuring Period, if, during
                        the entire term of the first Measuring Period, Warrant
                        Holder does not voluntarily participate in any "demand
                        collection system" (as defined in Section 4 (d)) other
                        than the Company's and its affiliates' airline ticket
                        services.

            (c) Measuring Periods and Net Revenue.

                  (i)   As used in this Warrant Agreement, the term "Measuring
                        Period" shall mean a 12-month period, with the first
                        such Measuring Period commencing on the Date the Warrant
                        Holder first provides tickets for sale by the Company
                        following the Grant Date (the "First Ticket Date").
                        Subsequent Measuring Periods will expire on the second,
                        third, fourth and fifth anniversary of the First Ticket
                        Date, respectively, except that the fifth Measuring
                        Period shall end on the fifth (5Th) anniversary of the
                        Issue Date.

                  (ii)  As used in this Warrant Agreement, the term "Net
                        Revenue" shall mean the total ticket revenue received by
                        the Company from tickets sold for travel on the Warrant
                        Holder and its Code Share Partners, net of federal
                        excise and segment taxes, passenger facility charges and
                        related fees. The parties acknowledge that credit card
                        processing fees, and any processing fees or similar fees
                        charged by the Company to the consumer in connection
                        with the sale of a ticket shall not be included in the
                        calculation of Net Revenue..

                  (iii) As used in this Warrant Agreement, the term "Fair Share"
                        shall mean Warrant Holder's domestic market share
                        calculated as a fraction, the numerator of which shall
                        be Warrant Holder's RPM's for U.S. originating O&D's
                        only, and the denominator of which shall be the total
                        RPM's for U.S. originating O&D's only of all of the
                        Company's participating airlines.

            (d)   Warrant Holder's right to early exercise under Section 4(b) is
                  contingent upon Airline's participating exclusively in the
                  Company's leisure airline ticket service as the only "demand
                  collection system" for Warrant Holder's sale of airline
                  tickets over the Internet. For purposes of this Section 4(d),
                  "demand collection system" is narrowly defined as an airline
                  ticket service that (i) enables a consumer to name the price
                  the consumer willing to pay for one or more airline tickets
                  (ii) enables the seller to bind the consumer to the consumer's
                  offer price upon the seller's acceptance of the consumer's
                  offer, and (iii) does not permit the consumer to specify the
                  exact airline on which the consumer is willing to fly. In
                  order for Warrant Holder to be entitled to the early exercise
                  rights specified in Section 4(b), Warrant Holder must not at
                  any time between the date hereof and the date


                                      -3-

                  exercises an early exercise of Warrants in accordance with
                  Section 4(b) participate in any "demand collection system"
                  other than the Company's for the sale of airline tickets over
                  the Internet. For example, if in the first Measuring Period,
                  the Company achieves Net Revenues to that would entitle the
                  Warrant Holder to exercise Warrants for [**]% of the Shares,
                  the Warrant Holder will be entitle to exercise such Warrants
                  at all time thereafter so long as the Warrant Holder at all
                  times from the date hereof though the date of such exercise
                  has not participated in another "demand collection system" for
                  the sale of airline tickets over the Internet. If at any time
                  from the date hereof though to the fifth 5th anniversary of
                  the Grant Date, the Warrant Holder participates in another
                  "demand collection system" for the sale of airline ticket over
                  the Internet, the Warrant Holder's early exercise rights will
                  terminate and be of no further force or effect, and such
                  Warrants will become exercisable on the fifth 5th anniversary
                  of the Grant Date.

      5. Exercise of Purchase Rights.

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

            (b) Net Issue Exercise. Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Exercise Price (at the date of calculation as set forth below),
in lieu of exercising the Warrants for cash, the Warrant Holder may elect to
receive shares equal to the value (as determined below) of the Warrants (or
portion thereof being canceled) by surrender of the Warrants at the principal
office of the Company together with the duly executed Notice of Exercise in
which event the Company shall issue to the Warrant Holder a number of shares of
Common Stock computed using the following formula: X=Y(A-B)/ A WHERE X= the
number of shares of Common Stock to be issued to the Warrant Holder; Y= the
number of shares of the Common Stock purchasable under the Warrants or, if only
a portion of the Warrants is being exercised, the portion of the Warrants being
canceled (at the date of such calculation); A= the fair market value of one
share of the Company's Common Stock (at the date of such calculation); and B=
Exercise Price (at the date of such calculation). For purposes of the above
calculation, fair market value of one share of the Common Stock shall be equal
to the closing trading price of the Company's Common Stock on the day
immediately prior to the date the Notice of Exercise is tendered to the Company.

      6. Reservation of Shares. The Company will at all times have authorized
and reserved a sufficient number of shares of Common Stock to provide for the
exercise of the rights to purchase the Shares as provided in this Warrant
Agreement. All of the Shares shall be duly authorized and, when issued upon


                                      -4-
<PAGE>

such exercise, shall be validly issued, fully paid and nonassessable, and free
and clear of all preemptive rights.

      7. No Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant Holder's
rights to purchase the Shares.

      8. No Rights as Shareholder. This Warrant Agreement does not entitle the
Warrant Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrant Holder's rights to purchase the
Shares as provided for herein.

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

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

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

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

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

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


                                      -5-
<PAGE>

obtained by multiplying (i) the Exercise Price in effect immediately prior to
such adjustment by (ii) the number of shares of Common Stock issuable upon the
exercise hereof immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

            (e) Other Changes. If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 10 are not strictly applicable or if strictly applicable, would not
fairly protect the purchase rights of the Warrant Holder in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number of and class of shares available under the Warrants, the Exercise
Price or the application of such provisions, so as to protect the purchase
rights of the Warrant Holder. The adjustment shall be such as will give the
Warrant Holder upon exercise for the same aggregate Exercise Price the total
number, class and kind of shares or other property as the Warrant Holder would
have owned had the Warrants been exercised prior to the event and had the
Warrant Holder continued to hold such shares until after the event requiring
adjustment.

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

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

      11. Representations and Warranties of the Warrant Holder.

      The Warrant Holder hereby represents and warrants to the Company as

hereby.

            (d) Binding Effect. This Warrant Agreement has been duly executed
and delivered by the Warrant Holder and constitutes the valid and binding
obligations of the Warrant Holder, enforceable against it in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,

<PAGE>

insolvency, reorganization, fraudulent conveyance or transfer, moratorium or
similar laws affecting the enforcement of creditors' rights generally or by
equitable principles relating to enforceability (regardless of whether
considered in a proceeding at law or in equity).

            (e) Purchase for Own Account. The Warrants issued to the Warrant
Holder pursuant to this Warrant Agreement, and the Shares to be issued upon
vesting and exercise thereof, are being or will be acquired for the Warrant
Holder's own account and with no intention of distributing or reselling such
securities or any part thereof in any transaction that would be in violation of
the securities laws of the United States of America, or any state.

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

conditions of the Warrants, the business of the Company, and to obtain
additional information to such Warrant Holder's satisfaction.

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

      12. Compliance with Securities Act; Transferability of Warrant or Shares
of Common Stock.

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

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


                                      -7-
<PAGE>

      (b) Exchange, Transfer, Assignment. The Warrants cannot be exchanged,
transferred or assigned otherwise than in accordance with applicable law. Upon
compliance with applicable law and surrender of the Warrants to the Company with
the Assignment Form annexed hereto as Exhibit B duly executed, and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant Agreement in the name of the heir, devisee or assignee
named in such instrument of assignment and this Warrant Agreement shall promptly
be canceled. Subject to the terms hereof, the Warrants may be assigned in whole
or in part.

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

form of Exhibit C hereto (with appropriate changes therein) shall each have all
the rights and obligations of a Demand Stockholder (as defined in such
Agreement) under such Agreement; provided that no registration statement with
respect to less than a minimum of 250,000 Shares shall be required to be
effected by the Company thereunder for the benefit of any such assignee.

                        Measuring Period for travel on the Warrant Holder and

                        [**]% of such Shares shall not accrue unless and until
                        the Company has, on an aggregated basis during the
                        applicable Measuring Period, received at least $[**]
                        million of Net Revenues from tickets sold during such
                        Measuring Period for travel on the Warrant Holder and
                        its Code Share Partners, and (ii) the right to exercise
                        Warrants for [**]% of such Shares shall not accrue
                        unless and until the Company has, on an aggregated basis
                        during the applicable Measuring Period, received at
                        least $[**] million of Net Revenues from tickets sold
                        during such Measuring Period for travel on the Warrant
                        Holder and its Code Share Partners.

                  (iii) Notwithstanding the Net Revenue benchmarks specified in
                        clauses (i) and (ii) of this Section 4(b) for the early
                        exercisability of Warrants, if, in any Measuring Period,
                        the Company fails to achieve the minimum Net Revenues
                        from ticket sales for travel on Warrant Holder and its
                        Code Share Partners necessary to enable Warrant Holder
                        to exercise Warrants for the [**]% or [**]% portion of
                        Shares that would otherwise become exercisable if such
                        benchmarks were achieved during such Measuring Period,
                        then, effective on the last day of such Measuring Period
                        and thereafter, Warrant Holder (i) shall have the right
                        to exercise Warrants for the [**]% portion of Warrants
                        that would otherwise become exercisable upon achieving
                        the corresponding Net Revenue benchmark for such
                        Measuring Period, if Warrant Holders and its Code Share
                        Partners' percentage of the aggregate of all ticket sale
                        revenues (calculated using the same methodology used to
                        calculate Net Revenue hereunder) received by the Company
                        for U.S. originating O&D's for such Measuring Period
                        equals or exceeds [**]% of Warrant Holder's Fair Share
                        (as defined in Section 4(c) below) (the "[**]% Fair
                        Share Threshold"), and (ii) shall have the right to
                        exercise Warrants for the [**]% portion of Warrants that
                        would otherwise become exercisable upon achieving the
                        corresponding Net Revenue benchmark for such Measuring
                        Period, if Warrant Holder's and its Code Share Partners'
                        percentage of the aggregate of all ticket sale revenues
                        received by the Company for U.S. originating O&D's for
                        such Measuring Period equals or exceeds [**]% of Warrant
                        Holder's Fair Share (the "[**]% Fair Share Threshold").

                  (iv)  In the event that the Company does not achieve the
                        $[**] million Net Revenue benchmark specified in
                        clauses (i) of this Section 4(b) and Warrant Holder does
                        not achieve the [**]% Fair Share Threshold specified in
                        clause (iii) of this Section 4(b) for the early
                        exercisability of Warrants for the first Measuring
                        Period, Warrant Holder shall have the right upon
                        completion of the first Measuring Period and thereafter
                        to exercise Warrants for the [**]% portion of Warrants
                        that would otherwise become exercisable upon the
                        Company's achieving the $[**] million Net Revenue
                        benchmark or Warrant Holder's achieving the [**]% Fair
                        Share Threshold for such Measuring Period, if, during
                        the entire term of the first Measuring Period, Warrant
                        Holder does not voluntarily participate in any "demand
                        collection system" (as defined in Section 4(d)) other
                        than the Company's airline ticket service.

            (c) Measuring Periods and Net Revenue.

                  (i)   As used in this Warrant Agreement, the term "Measuring
                        Period" shall mean a 12-month period, with the first
                        such Measuring Period commencing on the Date the Warrant
                        Holder first provides tickets for sale by the Company
                        following the Grant Date (the "First Ticket Date").
                        Subsequent Measuring Periods will expire on the second,
                        third, fourth and fifth anniversary of the First Ticket
                        Date, respectively, except that the fifth Measuring
                        Period shall end on the fifth (5Th) anniversary of the
                        Issue Date.

                  (ii)  As used in this Warrant Agreement, the term "Net
                        Revenue" shall mean the total ticket revenue received by
                        the Company from tickets sold for travel on the Warrant
                        Holder and its Code Share Partners, net of federal
                        excise and segment taxes, passenger facility charges and
                        related fees. The parties acknowledge that credit card
                        processing fees, and any processing fees or similar fees
                        charged by the Company to the consumer in connection
                        with the sale of a ticket shall not be included in the
                        calculation of Net Revenue..

                  (iii) As used in this Warrant Agreement, the term "Fair Share"
                        shall mean Warrant Holder's domestic market share
                        calculated as a fraction, the numerator of which shall
                        be Warrant Holder's RPM's for U.S. originating O&D's
                        only, and the denominator of which shall be the total
                        RPM's for U.S. originating O&D's only of all of the
                        Company's participating airlines.

            (d)   Warrant Holder's right to early exercise under Section 4(b) is
                  contingent upon Airline's participating exclusively in the
                  Company's leisure airline ticket service as the only "demand
                  collection system" for Warrant Holder's sale of airline
                  tickets over the Internet. For purposes of this Section 4(d),
                  "demand collection system" is narrowly defined as an airline
                  ticket service that (i) enables a consumer to name the price
                  the consumer is willing to pay for one or more airline
                  tickets, (ii) enables the seller to bind the consumer to the
                  consumer's offer price upon the seller's acceptance of the
                  consumer's offer, and (iii) does not permit the consumer to
                  specify the exact airline on which the consumer is willing to
                  fly. In order for Warrant Holder to be entitled to the early
                  exercise rights specified in Section 4(b), Warrant Holder must
                  not at any time between the date hereof and the date


                                      -3-
<PAGE>

                  exercises an early exercise of Warrants in accordance with
                  Section 4(b) participate in any "demand collection system"
                  other than the Company's for the sale of airline tickets over
                  the Internet. For example, if in the first Measuring Period,
                  the Company achieves Net Revenues to that would entitle the
                  Warrant Holder to exercise Warrants for [**]% of the Shares,
                  the Warrant Holder will be entitle to exercise such Warrants
                  at all time thereafter so long as the Warrant Holder at all
                  times from the date hereof though the date of such exercise
                  has not participated in another "demand collection system" for
                  the sale of airline tickets over the Internet. If at any time
                  from the date hereof though to the fifth 5th anniversary of
                  the Grant Date, the Warrant Holder participates in another
                  "demand collection system" for the sale of airline ticket over
                  the Internet, the Warrant Holder's early exercise rights will
                  terminate and be of no further force or effect, and such
                  Warrants will become exercisable on the fifth 5th anniversary
                  of the Grant Date.

      5. Exercise of Purchase Rights.

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

            (b) Net Issue Exercise. Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Exercise Price (at the date of calculation as set forth below),
in lieu of exercising the Warrants for cash, the Warrant Holder may elect to
receive shares equal to the value (as determined below) of the Warrants (or
portion thereof being canceled) by surrender of the Warrants at the principal
office of the Company together with the duly executed Notice of Exercise in
which event the Company shall issue to the Warrant Holder a number of shares of
Common Stock computed using the following formula: X=Y(A-B)/ A WHERE X= the
number of shares of Common Stock to be issued to the Warrant Holder; Y= the
number of shares of the Common Stock purchasable under the Warrants or, if only
a portion of the Warrants is being exercised, the portion of the Warrants being
canceled (at the date of such calculation); A= the fair market value of one
share of the Company's Common Stock (at the date of such calculation); and B=
Exercise Price (at the date of such calculation). For purposes of the above
calculation, fair market value of one share of the Common Stock shall be equal
to the closing trading price of the Company's Common Stock on the day
immediately prior to the date the Notice of Exercise is tendered to the Company.

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


                                      -4-
<PAGE>

      7. No Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant Holder's
rights to purchase the Shares.

      8. No Rights as Shareholder. This Warrant Agreement does not entitle the
Warrant Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrant Holder's rights to purchase the
Shares as provided for herein.

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

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

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

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

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

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


                                      -5-
<PAGE>

number of shares of Common Stock issuable upon the exercise hereof immediately
prior to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment.

            (e) Other Changes. If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 10 are not strictly applicable or if strictly applicable, would not
fairly protect the purchase rights of the Warrant Holder in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number of and class of shares available under the Warrants, the Exercise
Price or the application of such provisions, so as to protect the purchase
rights of the Warrant Holder. The adjustment shall be such as will give the
Warrant Holder upon exercise for the same aggregate Exercise Price the total
number, class and kind of shares or other property as the Warrant Holder would
have owned had the Warrants been exercised prior to the event and had the
Warrant Holder continued to hold such shares until after the event requiring
adjustment.

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

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

      11. Representations and Warranties of the Warrant Holder.

      The Warrant Holder hereby represents and warrants to the Company as

hereby.

            (d) Binding Effect. This Warrant Agreement has been duly executed
and delivered by the Warrant Holder and constitutes the valid and binding
obligations of the Warrant Holder, enforceable against it in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, fraudulent conveyance or transfer, moratorium or
similar laws affecting the

<PAGE>

enforcement of creditors' rights generally or by equitable principles relating

equity).

Holder pursuant to this Warrant Agreement, and the Shares to be issued upon
vesting and exercise thereof, are being or will be acquired for the Warrant

the securities laws of the United States of America, or any state.

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

conditions of the Warrants, the business of the Company, and to obtain
additional information to such Warrant Holder's satisfaction.

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

      12. Compliance with Securities Act; Transferability of Warrant or Shares
of Common Stock.

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

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


                                      -7-
<PAGE>

      (b) Exchange, Transfer, Assignment. The Warrants cannot be exchanged,
transferred or assigned otherwise than in accordance with applicable law. Upon
compliance with applicable law and surrender of the Warrants to the Company with
the Assignment Form annexed hereto as Exhibit B duly executed, and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant Agreement in the name of the heir, devisee or assignee
named in such instrument of assignment and this Warrant Agreement shall promptly
be canceled. Subject to the terms hereof, the Warrants may be assigned in whole
or in part.

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

Agreement and the Acknowledgment and Agreement to the Amended and Restated

registration rights pursuant to such Amended and Restated Registration Rights
Agreement dated as of December 8, 1998 to any assignee or assignees of all or
any part of this Warrant or the Shares issuable upon exercise hereof, which
assignees, upon their execution and delivery of an Acknowledgment and Agreement
to the Amended and Restated Registration Rights Agreement substantially in the
form of Exhibit C hereto (with appropriate changes therein) shall each have all
the rights and obligations of a Demand Stockholder (as defined in such
Agreement) under such Agreement; provided that no registration statement with
respect to less than a minimum of 250,000 Shares shall be required to be
effected by the Company thereunder for the benefit of any such assignee.

                        and until the Company has, on an aggregated basis during
                        the first Measuring Period, received at least $[**]

                        and/or on the Warrant Holder's code share partners using
                        Warrant Holder's code (collectively, "Warrant Holder and
                        its Code Share Partners"), and (ii) the right to
                        exercise Warrants for [**]% of the Shares shall not
                        accrue unless and until the Company has, on an
                        aggregated basis during the first Measuring Period,
                        received at least $[**] million of Net Revenues from
                        tickets sold during such Measuring Period for travel on

                        subject to adjustment as provided in Section 10 hereof,

                        such lesser percentage of the Shares as shall constitute
                        all of the remaining Shares not then exercisable;
                        provided that (i) the right to exercise Warrants for
                        [**]% of such Shares shall not accrue unless and until
                        the Company has, on an aggregated basis during the
                        applicable Measuring Period, received at least $[**]
                        million of Net Revenues from tickets sold during such
                        Measuring Period for travel on the Warrant Holder and
                        its Code Share Partners, and (ii) the right to exercise
                        Warrants for [**]% of such Shares shall not accrue
                        unless and until the Company has, on an aggregated basis
                        during the applicable Measuring Period, received at
                        least $[**] million of Net Revenues from tickets sold
                        during such Measuring Period for travel on the Warrant
                        Holder and its Code Share Partners.

                  (iii) Notwithstanding the Net Revenue benchmarks specified in
                        clauses (i) and (ii) of this Section 4(b) for the early
                        exercisability of Warrants, if, in any Measuring Period,
                        the Company fails to achieve the minimum Net Revenues
                        from ticket sales for travel on Warrant Holder and its
                        Code Share Partners necessary to enable Warrant Holder
                        to exercise Warrants for the [**]% or [**]% portion of
                        Shares that would otherwise become exercisable if such
                        benchmarks were achieved during such Measuring Period,
                        then, effective on the last day of such Measuring Period
                        and thereafter, Warrant Holder (i) shall have the right
                        to exercise Warrants for the [**]% portion of Warrants
                        that would otherwise become exercisable upon achieving
                        the corresponding Net Revenue benchmark for such
                        Measuring Period, if Warrant Holders and its Code Share
                        Partners' percentage of the aggregate of all ticket sale
                        revenues (calculated using the same methodology used to
                        calculate Net Revenue hereunder) received by the Company
                        for U.S. originating O&D's for such Measuring Period
                        equals or exceeds [**]% of Warrant Holder's Fair Share
                        (as defined in Section 4(c) below) (the "[**]% Fair
                        Share Threshold"), and (ii) shall have the right to
                        exercise Warrants for the [**]% portion of Warrants that
                        would otherwise become exercisable upon achieving the
                        corresponding Net Revenue benchmark for such Measuring
                        Period, if Warrant Holder's and its Code Share Partners'
                        percentage of the aggregate of all ticket sale revenues
                        received by the Company for U.S. originating O&D's for
                        such Measuring Period equals or exceeds [**]% of Warrant
                        Holder's Fair Share (the "[**]% Fair Share Threshold").

<PAGE>

                  (iv)  In the event that the Company does not achieve the $83.3
                        million Net Revenue benchmark specified in clauses (i)
                        of this Section 4(b) and Warrant Holder does not achieve
                        the [**]% Fair Share Threshold specified in clause (iii)
                        of this Section 4(b) for the early exercisability of
                        Warrants for the first Measuring Period, Warrant Holder
                        shall have the right upon completion of the first
                        Measuring Period and thereafter to exercise Warrants for
                        the [**]% portion of Warrants that would otherwise
                        become exercisable upon the Company's achieving the
                        $[**] million Net Revenue benchmark or Warrant Holder's
                        achieving the [**]% Fair Share Threshold for such
                        Measuring Period, if, during the entire term of the
                        first Measuring Period, Warrant Holder does not
                        voluntarily participate in any name-your-price airline
                        ticket service other than the Company's and its
                        affiliates' airline ticket services.

            (c) Measuring Periods and Net Revenue.

                  (i)   As used in this Warrant Agreement, the term "Measuring
                        Period" shall mean a 12-month period, with the first
                        such Measuring Period commencing on the Date the Warrant
                        Holder first provides tickets for sale by the Company
                        following the Grant Date (the "First Ticket Date").
                        Subsequent Measuring Periods will expire on the second,
                        third, fourth and fifth anniversary of the First Ticket
                        Date, respectively, except that the fifth Measuring
                        Period shall end on the fifth (5Th) anniversary of the
                        Issue Date.

                  (ii)  As used in this Warrant Agreement, the term "Net
                        Revenue" shall mean the total ticket revenue received by
                        the Company from tickets sold for travel on the Warrant
                        Holder and its Code Share Partners, net of federal
                        excise and segment taxes, passenger facility charges and
                        related fees. The parties acknowledge that credit card
                        processing fees, and any processing fees or similar fees
                        charged by the Company to the consumer in connection
                        with the sale of a ticket shall not be included in the
                        calculation of Net Revenue..

                  (iii) As used in this Warrant Agreement, the term "Fair Share"
                        shall mean Warrant Holder's domestic market share
                        calculated as a fraction, the numerator of which shall
                        be Warrant Holder's RPM's for U.S. originating O&D's
                        only, and the denominator of which shall be the total
                        RPM's for U.S. originating O&D's only of all of the
                        Company's participating airlines.

            (d)   Warrant Holder's right to early exercise under Section 4(b) is
                  contingent upon Airline's participating exclusively in the
                  Company's leisure airline ticket service as the only "demand
                  collection system" for Warrant Holder's sale of airline
                  tickets over the Internet. For purposes of this Section 4(d),
                  "demand collection system" is narrowly defined as an airline
                  ticket service that (i) enables a consumer to name the price
                  the consumer willing to pay for one or more airline tickets
                  (ii) enables the seller to bind requires the consumer to the
                  consumer's offer price upon the seller's acceptance of the
                  consumer's offer, and (iii) does not permit the consumer to
                  specify the exact airline on which the consumer is willing to
                  fly. In order for


                                      -3-
<PAGE>

                  Warrant Holder to be entitled to the early exercise rights
                  specified in Section 4(b), Warrant Holder must not at any time
                  between the date hereof and the date exercises an early
                  exercise of Warrants in accordance with Section 4(b)
                  participate in any "demand collection system" other than the
                  Company's for the sale of airline tickets over the Internet.
                  For example, if in the first Measuring Period, the Company
                  achieves Net Revenues to that would entitle the Warrant Holder
                  to exercise Warrants for [**]% of the Shares, the Warrant
                  Holder will be entitle to exercise such Warrants at all time
                  thereafter so long as the Warrant Holder at all times from the
                  date hereof though the date of such exercise has not
                  participated in another "demand collection system" for the
                  sale of airline tickets over the Internet. If at any time from
                  the date hereof though to the fifth 5th anniversary of the
                  Grant Date, the Warrant Holder participates in another "demand
                  collection system" for the sale of airline ticket over the
                  Internet, the Warrant Holder's early exercise rights will
                  terminate and be of no further force or effect, and such
                  Warrants will become exercisable on the fifth 5th anniversary
                  of the Grant Date.

      5. Exercise of Purchase Rights.

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

            (b) Net Issue Exercise. Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Exercise Price (at the date of calculation as set forth below),
in lieu of exercising the Warrants for cash, the Warrant Holder may elect to
receive shares equal to the value (as determined below) of the Warrants (or
portion thereof being canceled) by surrender of the Warrants at the principal
office of the Company together with the duly executed Notice of Exercise in
which event the Company shall issue to the Warrant Holder a number of shares of
Common Stock computed using the following formula: X=Y(A-B)/ A WHERE X= the
number of shares of Common Stock to be issued to the Warrant Holder; Y= the
number of shares of the Common Stock purchasable under the Warrants or, if only
a portion of the Warrants is being exercised, the portion of the Warrants being
canceled (at the date of such calculation); A= the fair market value of one
share of the Company's Common Stock (at the date of such calculation); and B=
Exercise Price (at the date of such calculation). For purposes of the above
calculation, fair market value of one share of the Common Stock shall be equal
to the closing trading price of the Company's Common Stock on the day
immediately prior to the date the Notice of Exercise is tendered to the Company.

      6. Reservation of Shares. The Company will at all times have authorized
and reserved a sufficient number of shares of Common Stock to provide for the
exercise of the rights to purchase the Shares


                                      -4-
<PAGE>

as provided in this Warrant Agreement. All of the Shares shall be duly
authorized and, when issued upon such exercise, shall be validly issued, fully
paid and nonassessable, and free and clear of all preemptive rights.

      7. No Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant Holder's
rights to purchase the Shares.

      8. No Rights as Shareholder. This Warrant Agreement does not entitle the
Warrant Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrant Holder's rights to purchase the
Shares as provided for herein.

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

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

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

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

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

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


                                      -5-
<PAGE>

from such adjustment, the number of shares of Common Stock (calculated to the
nearest whole share) obtained by multiplying (i) the Exercise Price in effect
immediately prior to such adjustment by (ii) the number of shares of Common
Stock issuable upon the exercise hereof immediately prior to such adjustment and
dividing the product thereof by the Exercise Price resulting from such
adjustment.

            (e) Other Changes. If any change in the outstanding Common Stock of
the Company or any other event occurs as to which the other provisions of this
Section 10 are not strictly applicable or if strictly applicable, would not
fairly protect the purchase rights of the Warrant Holder in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number of and class of shares available under the Warrants, the Exercise
Price or the application of such provisions, so as to protect the purchase
rights of the Warrant Holder. The adjustment shall be such as will give the
Warrant Holder upon exercise for the same aggregate Exercise Price the total
number, class and kind of shares or other property as the Warrant Holder would
have owned had the Warrants been exercised prior to the event and had the
Warrant Holder continued to hold such shares until after the event requiring
adjustment.

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

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

      11. Representations and Warranties of the Warrant Holder.

      The Warrant Holder hereby represents and warrants to the Company as

<PAGE>

against it in accordance with its terms, except as enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or
transfer, moratorium or similar laws affecting the enforcement of creditors'
rights generally or by equitable principles relating to enforceability
(regardless of whether considered in a proceeding at law or in equity).

the securities laws of the United States of America, or any state.

            (f) Restricted Securities. The Warrant Holder understands that the
Warrants and the Shares issuable upon vesting and exercise of the Warrants, will
not be registered at the time of their issuance under the Securities Act for the
reason that the sale provided for in this Agreement is exempt pursuant to
Section 4(2) of the Securities Act and that reliance of the Company on such
exemption is predicated in part on such Warrant Holder's representations set

Investor" within the meaning of Rule 501 of Regulation D under the Securities
Act, as presently in effect.

      12. Compliance with Securities Act; Transferability of Warrant or Shares

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

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


                                      -7-
<PAGE>

      (b) Exchange, Transfer, Assignment. The Warrants cannot be exchanged,
transferred or assigned otherwise than in accordance with applicable law. Upon
compliance with applicable law and surrender of the Warrants to the Company with
the Assignment Form annexed hereto as Exhibit B duly executed, and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant Agreement in the name of the heir, devisee or assignee
named in such instrument of assignment and this Warrant Agreement shall promptly
be canceled. Subject to the terms hereof, the Warrants may be assigned in whole
or in part.

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

form of Exhibit C hereto (with appropriate changes therein) shall each have all
the rights and obligations of a Demand Stockholder (as defined in such
Agreement) under such Agreement; provided that no registration statement with
respect to less than a minimum of 250,000 Shares shall be required to be
effected by the Company thereunder for the benefit of any such assignee.

                         CONTINUING EMPLOYMENT AGREEMENT

      This Continuing Employment Agreement ("Agreement ") is made effective as
of December 16, 1999 between priceline.com, Incorporated, a Delaware corporation
having an office located at Five High Ridge Park, Stamford, Connecticut 06905
(the "Company"), Walker Digital Corporation, a Connecticut corporation, having
an office located at One High Ridge Park, Stamford, Connecticut 06905 ("Walker
Digital") (the Company and Walker Digital are sometimes referred to herein
collectively as the "Companies"), and Melissa M. Taub, residing at 90 Pumping
Station Road, Ridgefield, Connecticut 06877 (the "Employee").

      In consideration of the covenants and promises set forth below, the
Companies and the Employee, intending to be bound legally, agree as follows:

1. Resignation of Officer Positions and Change of Duties.

(a) The Employee hereby resigns as an officer and director of the Companies and
each subsidiary of the Companies effective as of the date hereof. The Company
acknowledges that the Employee shall not be considered an officer of the Company
for purposes of the Securities Exchange Act of 1934, as amended, including
Section 16(b) thereof, after the date hereof.

(b) The Companies and the Employee have mutually agreed that the Employee's
employment relationship with the Company shall continue from the date hereof and
shall terminate as of December 16, 2000 (the "Termination Date").

(c) For the period commencing on December 17, 1999 and ending on the Termination
Date, the Employee shall continue to serve as a non-officer employee of the
Companies. During this period, the Employee's duties as an employee will be only
those which are mutually agreed between her and the Companies, with the
Companies' decision as to such duties to be determined solely by Paul Francis.
As a result, the Companies agree that notwithstanding any of the provisions of
the Employment Letter dated September 10, 1998 (the "Employment Letter"), the
Employee's employment with the Companies will not be terminated by the Companies
prior to the Termination Date.

2. Consideration. In exchange for a waiver and release, as set forth on Exhibit
A hereto, of any claims that the Employee has or may have against the Companies
and vice versa which the Employee and the Companies will deliver upon
<PAGE>

execution of this Agreement, and in lieu of any other benefits to which the
Employee is or may be entitled under the Company's employment and severance
policies or under the Employment Letter, the Companies and the Employee have
agreed that Employee shall continue employment with the Company on the terms and
conditions set forth herein. As additional consideration for her continued
employment with the Company hereunder, the Companies and the Employee hereby
agree to execute an identical waiver and release with respect to the Company as
of the Termination Date.

(a) Salary Continuation. The Employee shall be entitled to continuation of base
salary of $200,000 per year, payable in accordance with the Company's regular
payroll practices, through the Termination Date, subject to Section 2(i) hereof.

(b) Bonus. The Employee shall be entitled to receive a bonus for fiscal year
1999, in the amount of $22,700, which bonus shall be paid by the Company no
later than December 31, 1999.

(c) Stock Options. The Employee currently holds unexercised options ("Employee
Options") to purchase an aggregate of 200,000 shares of Common Stock of the
Company ("Underlying Common Stock") granted pursuant to the priceline.com LLC
1997 Omnibus Plan ("1997 Omnibus Plan"), and in accordance with the
priceline.com LLC Non-Qualified Option Agreement Pursuant to the 1997 Omnibus
Plan, dated as of July 18, 1998 ("Option Agreement"). Notwithstanding anything
else to the contrary including the provisions of the 1997 Omnibus Plan or the
Option Agreement:

      (i)   116,667 of the Employee Options are fully vested as of the date of
            this Agreement Date (the "Current Vested Options");

      (ii)  83,333 of the Employee Options will fully vest on June 1, 2000
            without any risk of forfeiture (the "Future Vested Options").
            Vesting of the Future Vested Options will occur simply with the
            passage of time and the Future Vested Options will be fully vested
            on June 1, 2000.

      (iii) the Employee shall be entitled to exercise the Current Vested
            Options, in whole or in part and from time to time, during the
            period commencing with the date hereof and ending 90 days after the
            Termination Date;
<PAGE>

      (iv)  the Employee shall be entitled to exercise the Future Vested
            Options, in whole or in part and from time to time, during the
            period commencing on June 1, 2000 and ending 90 days after the
            Termination Date;

      (v)   the Executive's execution and compliance with the terms of this
            Agreement shall be deemed to constitute compliance with the
            provisions of paragraphs 6(b), (c) and (d) of the Option Agreement
            and any similar provisions of the 1997 Omnibus Plan;

      (vi)  subject to the limitations set forth in the letter between the
            Employee and the Company dated July 18, 1999 (the "Lock-Up Letter")
            and any policy of the Company in effect during the term of this
            Agreement with respect to the sale by its employees of its Common
            Stock, the Employee shall be entitled upon exercise of the Employee
            Options to sell the Underlying Common Stock to the public pursuant
            to the S-8 Registration Statement (Registration No. 333-83233) ("S-8
            Registration Statement"), or another such Registration Statement
            covering option shares which supercedes the S-8 Registration
            Statement;

      (vii) the Company agrees that Employee shall not be required to enter into
            a new lock-up agreement after the expiration of the Lock-Up Letter;

      (viii) the Company agrees that it will keep the S-8 Registration Statement
            effective for the benefit of the Employee for the same period of
            time as the same is kept effective for the benefit of any other
            employee of the Company;

      (ix)  the Company agrees that it shall withhold from the number of shares
            otherwise to be delivered upon exercise of the Employee Options a
            number of shares of Underlying Common Stock having a fair market
            value equal to or less than the Company's aggregate withholding tax
            obligation with respect to exercise of the Employee Options;

      (x)   the Company agrees it will permit a cashless exercise of the
            Employee Options, which means that assuming a simultaneous exercise
            of the Employee Options and sale of some or all of the Underlying
            Common Stock, Employee may deliver to the Company out of the sale
            proceeds a sum equal to the exercise price and withholding tax
            obligation for all Employee Options exercised.
<PAGE>

Except as modified by this Agreement, the Employee shall be entitled to all the
other rights and benefits relating to the Employee Options which are set forth
in the 1997 Omnibus Plan and the Option Agreement.

(d) Walker Digital Options. The Employee shall be granted as of the date hereof
non-qualified stock options for 25,000 shares of Walker Digital common stock
pursuant to the Walker Digital 1999 Stock Option Plan (the "Walker Digital
Option Plan") at an exercise price per share of $1.00. Such options shall be
fully vested on grant and shall terminate on December 16, 2009 notwithstanding
anything else to the contrary in the Walker Digital Option Plan, and shall
otherwise have such terms and conditions as are set forth in the Walker Digital
Option Plan and any related stock option agreement.

(e) Medical and Dental Plans. The Employee shall be entitled to continuation of
group health benefits (medical and dental) as well as life and disability
insurance pursuant to the Company's standard programs as in effect from time to
time, in accordance with the terms of such plans as applicable to employees
generally, until the Termination Date. Thereafter, the Employee shall be
entitled to continuation of such benefits under the Company's standard programs
as in effect from time to time (or continuation of substantially similar
benefits, through a third party carrier, at the Company's election) for a period
of up to 18 months (or in the case of health benefits, such longer period as may
be required by COBRA), provided that the Employee makes any necessary conversion
and pays the full cost of the premium.

(f) Other Benefits. The Employee shall be entitled to continued participation in
all other employee and Employee benefits plans of the Company (other than the
right to participate in the Company's stock and option plans, except as
otherwise set forth in this Agreement) until the earlier of (i) the Termination
Date and (ii) such date that Employee accepts alternative employment with any
employer other than the Company or Walker Digital providing similar benefits.
Such benefits include without limitation the right to participate in the
Company's 401(k) plan, and workers' compensation and unemployment programs.

(g) Company Equipment. Notwithstanding the terms of the Confidentiality
Agreement referenced in Section 3 below, the Employee may keep her
Company-issued home computer, fax printer and cellular telephone (with continued
telephone service after the Termination Date at the Employee's cost). The
Employee will return any other Company equipment to the Company on or before the
Termination Date.
<PAGE>

(h) Continued Indemnification and Insurance. As a former officer and employee of
the Companies, Employee shall continue to be entitled to the benefit of the
indemnification provisions contained in the Certificates of Incorporation and
By-Laws of the Companies with respect to any acts or omissions that occurred
during her tenure as an officer and employee. In addition, the Employee shall
continue to be entitled to the benefit of coverage under all director and
officer and professional risk/liability (legal malpractice) insurance policies,
maintained by the Company with respect to any acts or omissions that occurred
during her tenure as an officer and employee. At a minimum, the Company agrees
to keep and maintain such policies in full force and effect (and on terms no
less favorable then the terms now in effect) until such time as the Employee has
no legal or other liability for any acts or omissions that occurred during her
tenure as an officer and employee.

(i) Potential Loss of Salary. Notwithstanding the salary continuation set forth
in paragraph 2(a) above, the Employee agrees that if the Employee performs
services for any entity other than any of the Companies or is self-employed
during the period from June 16, 2000 to December 16, 2000, any amounts received
by the Employee that are recognized as income to the Employee for such period
from such other entity or from self-employment (other than income resulting from
the exercise of stock options, the grant or vesting of other equity awards or
other similar events, including the sale of Underlying Common Stock) will offset
on a dollar-for-dollar basis the Company's obligation to continue to make salary
payments to the Employee pursuant to paragraph 2(a). The Employee is under no
obligation to mitigate or seek employment prior to the Termination Date.

(j) No Severance or Other Benefits. The Company and the Employee agree that the
Employee will be entitled to no severance or other benefits except as expressly
set forth herein.

3. Confidentiality Agreement. The Employee acknowledges that the Employee's
obligations to the Company set forth in the Employee's Confidentiality
Agreement, dated September 10, 1998, remain in full force and effect and are not
diminished in any way by this Agreement. Any time periods contained in such
agreement for post-termination obligations shall be deemed to commence as of the
Termination Date.

4. Non-Disclosure. The Company and the Employee agree not to disclose the
provisions of this Agreement to any person or entity, with the exception of
counsel, accounting and tax advisors, Employee's immediate family, or as
required by applicable law. However, since the fact of Employee's resignation as
an officer of the Company requires public disclosure and the filing of a form
8-K report
<PAGE>

with the Securities and Exchange Commission, the Company and the Employee agree
to cooperate in all such public disclosure and in the making of such 8-K filing,
with Employee to have approval authority over the content of such disclosure and
filing. In addition, the Employee shall have the right to approve communications
to personnel of the Companies and all other third parties concerning the
Employee's termination of employment with the Companies.

5. Mutual Non-Disparagement. The Employee and the Companies agree not to make
any statement, written or verbal, to any party reasonably likely to be harmful
to the other party or to be injurious to the goodwill, reputation or business
standing of the other party at any time in the future; provided, however, that
this non-disparagement clause shall not preclude any party or its agents or
representatives from any good faith response to any inquiries under oath or in
response to governmental inquiry.

6. Mutual Release of Claims with Respect to the Company. The Employee and the
Companies agree to deliver the Mutual Release of Claims and Waiver of Rights
document in the form attached hereto as Exhibit A both (i) on or prior to
December 16, 1999, to be effective as of such date and (ii) on or prior to the
Termination Date, to be effective as of such date.

7. Merger and Integration. Except as expressly set forth herein, all prior
understandings and agreements between the parties are merged into this
Agreement, which collectively with the Mutual Release of Claims and Waiver of
Rights, express the complete understanding and agreement between the parties.

8. Advice of Counsel. The Employee acknowledges and represents that the Employee
has had the opportunity to obtain the advice of counsel, and is entering into
this Agreement after carefully considering the legal ramifications thereof. The
Employee acknowledges and represents that the Employee is entering into these
agreements voluntarily, knowingly of the Employee's own free will, and without
undue influence or duress.

convenience of reference only, are not intended to be a part of this Agreement

intent of any of the terms, covenants or conditions of this Agreement.

10. Severability. If any term or provision of this Agreement or the application
thereof to any person, entity or circumstance shall to any extent be determined
by a court of competent jurisdiction to be invalid or unenforceable, the
<PAGE>

remainder of this Agreement, or the application of such terms or provision to
such person, entity or circumstance other than those that are held invalid or
unenforceable, shall not be affected thereby, and each other term and provision
shall be valid and enforced to the fullest extent permitted by law. The parties
authorize the court to reduce in scope or modify, if possible, all invalid or
unenforceable provisions, so that they become valid or enforceable.

                  MUTUAL RELEASE OF CLAIMS AND WAIVER OF RIGHTS

shareholders, employees and agents (such other persons being collectively
referred to for the purposes of this document as the "the Company Persons"), and
(b) the Companies, on behalf of themselves and the Company Persons, in
consideration of the terms and conditions set forth herein and other good and
valuable consideration, the receipt and sufficiency of which is hereby

accounts, reckonings, bonds, bills, specialties, covenants, contracts,
controversies, agreements, promises, variances, trespasses, judgments, extents,
executions, costs and expenses of any nature whatsoever, except for the
obligations set forth in the Continuing Employment Agreement dated as of
December 16, 1999 between the Employee and the Companies ("Continuing Employment
Agreement"), but including, without limitation, court costs and attorneys' fees,
whether or not now known, claimed or suspected, fixed or contingent, in law or
in equity (hereinafter collectively referred to as "Claims") which the
respective releasing party (in each case, the "Releasor") now has, has ever had,
has ever claimed to have had or may have against the respective released party
(in each case, the "Releasee") from the beginning of the world to the date of
the execution of this Mutual Release of Claims, including without limitation:
any and all Claims for violation of the common law, including, but not limited
to, wrongful discharge of employment, breach of contract -- express or implied,

1967, 29 U.S.C.ss.621 et seq. (the "ADEA"), Title VII of the Civil Rights Act of
1964, 42 U.S.C.ss.2000 et seq., the Americans with Disabilities Act of 1990, 42
U.S.C.ss.12101, et seq., the Family and Medical Leave Act of 1993, 29 U.S.C.ss.
2601, et seq., the Equal Pay Act of 1963, the Fair Labor Standards Act of 1938,
29 U.S.C. ss.201, the Civil Rights Act of 1991, the Employee Retirement Income
Security Act of 1974, 29 U.S.C.ss.201 et seq., the Connecticut Fair Employment

conditions of the Employee's employment or cessation of employment with the
Companies; any and all Claims arising directly or indirectly out of the

entitled to any personal recovery in any Claim whatsoever against any Releasee
for any of the matters set forth in this paragraph.

in the Continuing Employment Agreement, all prior understandings and agreements
between the parties are merged into this Agreement, which constitutes the
complete understanding and agreement between the parties.

      Each Releasor acknowledges that certain states provide that a general
release of claims does not extend to claims which the Releasor does not know or
suspect to exist in the Releasor's favor at the time of executing the release
which, if known by the Releasor may have materially affected the Releasor's
entering into the release of claims. Being aware that such statutory protection
may be available to the Releasor, each Releasor expressly, voluntarily and
knowingly waives any arguable benefit or protection of any such statute in
executing this Mutual Release of Claims, known or unknown.

      Each Releasor further acknowledges that the Releasor's signature below
signifies that the Releasor is entering into this Mutual Release of Claims
freely, knowingly and voluntarily with a full understanding of its terms.

      This Release may not be changed orally.

2. Waiver of Rights. The Employee understands that there are various state,
federal and local laws that prohibit employment discrimination on the basis of,
among other things, age, sex, race, national origin, religion and disability and
that these laws are enforced by various government agencies. The Employee
intends to waive and hereby does waive any right that the Employee may have to
seek or be entitled to any personal recovery against the Companies under the Age
Discrimination in Employment Act of 1967 as amended (the "ADEA"), and under
<PAGE>

any other laws regarding employment discrimination with respect to her
employment with the Companies. The Employee acknowledges and understands that
the release of claims under the ADEA is subject to special waiver protections
under 29 U.S.C. 626(f). In accordance with that section, the Employee
specifically agrees that the Employee is knowingly and voluntarily releasing and
waiving any rights or claims of discrimination under the ADEA. The Employee
specifically acknowledges that the waiver of rights contained herein and the
Mutual Release of Claims fully comply with 29 U.S.C. ss. 626(f) in that:

            the Employee and the Company and are fully understood by the
            Employee;

      (ii)  the waiver and Release of Claims specifically refer to rights or
            claims arising under the ADEA;

      (iii) this waiver and the Release of Claims do not apply to any rights
            arising after the date of execution of this Agreement;

      (iv)  the Employee is waiving rights or claims for age discrimination
            under the ADEA in exchange for the consideration described in the
            Continuing Employment Agreement, which provides additional value
            relative to anything of value to which the Employee already is
            entitled;

      (v)   the Employee has been advised in writing to consult with an attorney
            prior to executing this Agreement and has in fact consulted with an
            attorney of her choice;

      (vi)  the parties agree that the Employee has had at least twenty-one (21)
            days within which to consider this Agreement;

      (vii) this Agreement provides the Employee with a period of 7 days
            following the execution of this Agreement to revoke the Agreement;
            and

      (viii) this Agreement will not become effective until the revocation
            period set forth in the preceding clause (vii) shall have expired.

3. Rescission Period; Effective Date.
