                           Greenlight Competitor approach AutoTrader to request
                           the purchase of rights to send e-mail messages to the
                           Registered User List, Greenlight shall have right of
                           first refusal to purchase the right to send an
                           additional e-mail message (in addition to those

                           user. In the event that Greenlight does not exercise
                           its right of first refusal, AutoTrader will be free
                           to sell the right to the Greenlight Competitor.

                           2.4.1.1  Newsletter Participation Option. Greenlight

                                    sent to the Registered Users List. Each
                                    newsletter will contain up to four

                                    and approved by AutoTrader. The first
                                    partner message shown in the newsletter
                                    shall be the lead partner and such partner
                                    shall pay Seven Cents ($0.07) for each
                                    addressee receiving the e-mail message. All
                                    other partners shall pay Five Cents ($0.05)

                                    participates in any such newsletter,
                                    Greenlight shall pay AutoTrader the

                                    generated by Greenlight's purchase of the

                                    Users List and Greenlight's participation in
                                    any AutoTrader newsletter e-mails will count
                                    toward the bonus traffic targets outlined in
                                    Section 3.4.

event that Phase II commences on other than the first day of a calendar month,
or the Term of this Agreement ends on other than the last day of a calendar
month, the slotting fees and numbers of required Click-Throughs for any month

calendar month shall be pro-rated based on the number of days in the applicable
period of performance during the month as compared to the number of days in the
calendar month.

AUTOTRADER.COM, LLC, with its principal place of business at 5775 Peachtree
Dunwoody Road, Suite A- 200, Atlanta, Georgia 30342 ("ATC").

                                  BACKGROUND

         A. eBay operates a website for the online, person-to-person trading of
various items.

         B. ACT operates a website that brings together buyers and sellers of
used cars and trucks via electronic classified ads as well as providing users
buying and selling tips, car reviews, vehicle pricing information, safety
information, and help with finance, insurance, and warranty programs.

         C. eBay and ATC want to enter into an interactive marketing
arrangement whereby both parties will cooperate to develop and launch a
co-branded automobile trading area hosted and maintained by eBay as part of the
eBay website for the general trading of certain automobiles in the U.S. and to
provide transaction-related products and services to users of the co-branded
trading area. This relationship is further described below and is subject to
the terms and conditions set forth in this Agreement.

         The parties therefore agree as follows:

                                   AGREEMENT

1.    DEFINITIONS.

         1.1 "AOL AGREEMENTS" means the Interactive Marketing Agreement between
America Online, Inc. ("AOL") and ATC dated April 13, 1999, as amended from time
to time (the "ATC AOL Agreement") and the Amended and Restated Interactive
Marketing Agreement between AOL and eBay dated March 24, 1999, as amended from
time to time (the "eBay AOL Agreement").

         1.2 "ATC CONTENT" means all content or information, in any medium,

any text, music, sound, photographs, video, graphics or data, but excluding any
user generated content.

         1.3 "ATC DEALERS" means offline used vehicle dealers (both independents
and franchise operators) who are licensed by a state government to deal in
vehicles, who list or have listed Eligible Vehicles for sale on the ATC Site
and who list one or more Eligible Vehicles on the Co-Branded Pages during the
Term and whose eBay user IDs are provided to eBay by ATC.

ATC in the course of operating the ATC Site and designated by ATC for use in
conjunction with the parties' performance under this Agreement.

         1.5 "ATC SITE" means the website owned and operated by ATC accessible
at www.autotrader.com (or any successor URL) for the purpose of listing used
vehicles for sale, providing information about new vehicles, buying and selling
tips, pricing information, and access to vehicle finance, insurance, warranty
programs and other information or functionality provided by ATC from time to

         1.7 "CO-BRANDED PAGES" means all pages of the eBay/ATC co-branded

other items that are not Eligible Vehicles) hosted by eBay (including, without
limitation, any Java screens associated with the trading area or emails or
other direct communications sent to eBay Users or others by operation of the
trading area). The direct URL that will lead to the home page of the Co-Branded

and enables them to establish through a bidding process (or other dynamic price

eBay and ATC from time to time as provided in Section 2.7 ("Eligible Services").
"Eligible Services" may include services such as automobile finance, insurance,
inspections, shipping, escrow and warranty services and other
transaction-related services related to the listing or sale of Eligible
Vehicles. "Eligible Services" specifically exclude provision of automobile
parts, automobilia, license plates, accessories and die-cast models, and any
services with respect to vehicles that are not Eligible Vehicles.

         1.16 "ELIGIBLE VEHICLES" means general-production cars, minivans,
station wagons, pick-up trucks, sports cars, and sport utility vehicles, of any
class, make or model produced within fifteen (15) years of the Effective Date
and each anniversary of the Effective Date thereafter (so that, as of the
Effective Date, Eligible Vehicles includes vehicles produced from 1986-2000; on
the first anniversary of the Effective Date, vehicles produced from 1987-2001,
and so on) and located in and for sale in the United States. "Eligible
Vehicles" do not include any motorcycles, RVs, vehicles located and for sale
outside of the U.S., antique (more than 20 years old), customized, collector

vehicles produced within the last twenty (20) years of the Effective Date. At
any time during the Term that vehicles produced fifteen (15) to twenty (20)
years earlier than the applicable anniversary of the Effective Date are listed
on the Co-Branded Pages, all such vehicles will be treated as Eligible Vehicles
for all relevant purposes. Upon reasonable notice to ATC, eBay may determine
that vehicles produced fifteen (15) to twenty (20) years earlier than the
applicable anniversary of the Effective Date shall no longer be treated as
Eligible Vehicles, in which event ATC shall be free to withhold any such
listings from the Co-Branded Pages.

         1.17 "MARKETING SERVICES AGREEMENT" means the agreement between eBay
and ATC of even date herewith with respect to ATC's delivery of content and
services for the Co-Branded Pages.

         1.18 "MARKS" means the eBay Marks or the ATC Marks, as applicable.

         1.19 "MIRROR SITE" means a version of the Co-Branded Pages made

(including, without limitation, any personally identifiable information and any
demographic, psychographic or statistical information) or an item they are
listing, bidding on, buying or selling on the eBay Site or Co-Branded Pages,
and any associated transactional information (e.g., did the item sell or not,
what price the item sold at) that ATC obtains or learns about eBay Users' in
connection with the eBay Site and Co-Branded Pages (however it does so, whether
such information or data is transferred by eBay, provided by the eBay User,
extracted through traffic analysis, or otherwise). "User Information"
specifically excludes any information generated or supplied by an eBay User on
the ATC Site or independently derived or extracted by ATC from any eBay User
behavior on the ATC Site.

2. DEVELOPMENT AND IMPLEMENTATION.

         2.1 OVERVIEW. Implementation will take place in two phases, both as
described in Exhibit A, following the launch on the date the parties announce
their relationship of an initial set of Co-Branded Pages using work-arounds to
generate on-the-fly co-branding. Phase 1 will consist of development and the
deployment of a preliminary version of the Co-Branded Pages based on "Version
1.0" of the redesigned eBay general automotive area of the eBay Site (as
further described below) that will not have all of the features described in
this Agreement (and which the parties intend to make publicly available on the
World Wide Web in the second calendar quarter of 2000 or as soon thereafter as
technically feasible), and Phase 2 will consist of deployment of a more
fully-featured version of the Co-Branded Pages, as further described in Exhibit
A (Development Schedule).

         2.2 CO-BRANDED PAGES DEVELOPMENT. eBay will use reasonable commercial
efforts to develop and host the Co-Branded Pages in accordance with the
Development Schedule using an eBay-defined set of Page Templates. eBay may
change the Page Templates from time to time in its sole discretion. ATC
acknowledges and agrees that "Version 1.0" of the redesigned eBay general
automotive area of the eBay Site, as presented in page mockups reviewed by ATC
before the Effective Date and expected to be launched in April 2000, shall be
the baseline version of the look, feel, navigational and other visual and
design elements of the Co-Branded Pages and is not subject to ATC's approval.
Any changes to the look, feel, navigational and other visual and design
elements or changes in the location, appearance or other aspects of the
parties' branding elements on the Co-Branded Pages after the launch of "Version
1.0" of the general automotive area of the eBay Site must be mutually agreed on
by the parties, provided that eBay shall determine in its discretion, in
consultation with ATC, how to handle links to other areas of the eBay Site
dealing with vehicle and automobilia-related listings and services that are not
Eligible Vehicles or Eligible Services (such as collector cars, spare parts,
die-cast models, etc.).

         2.3 CO-BRANDING PHASES. When the Co-Branded Pages are made available
in Phase 1, the parties agree that the following co-branding will be included:

           2.3.1 ATC will provide a link branded with the eBay logo to the
Co-Branded Pages from the homepage of the ATC Site.

           2.3.2 eBay will provide a text link to the Co-Branded Pages from the
"Automotive" category header on the homepage of the eBay Site and will work
with ATC,

                                       4.
<PAGE>   5

subject to technical and user experience limitations, to create a form of
mutually-agreeable co-branding on appropriate Eligible Vehicle-related pages
linked to from each U.S. regional version of the eBay Site.

           2.3.3 eBay will co-brand each static page of the Co-Branded Pages.

eBay will use reasonable commercial efforts to implement, within six (6) months
after the Effective Date, a co-branded registration process (meaning that the
eBay registration pages presented to users from the Co-Branded Pages will have
both parties' Marks on the registration pages), and will co-brand all email
messages and other communications sent to users of the Co-Branded Pages unless
it is not technically feasible to do so. If eBay implements co-branding of
email types and other communications for any third party that it has not
co-branded with ATC branding elements, eBay will promptly implement co-branding
of such emails and other communications with ATC co-branding elements as well
to the extent that such co-branding is technically feasible for the message
types involved. ATC will also co-brand all communications sent to ATC Dealers
and other ATC Users regarding the Co-Branded Pages unless it is not technically
feasible to do so. If ATC implements co-branding of email types and other
communications for any third party that it has not co-branded with eBay
branding elements, ATC will promptly implement co-branding of such emails and
other communications with eBay co-branding elements as well to the extent that
such co-branding is technically feasible for the message types involved.

         2.4 TRAFFIC FLOW MANAGEMENT. The parties will design the Co-Branded
Pages with a view toward balancing the flow of traffic from the Co-Branded
Pages to the ATC Site and the eBay Site (other than to other automotive-related
areas), respectively, with the intention that any traffic that does flow out
from the Co-Branded Pages will flow to the eBay Site and the ATC Site in equal
proportions. To the extent commercially and technically feasible, the parties
will exchange traffic flow data and meet periodically to design measures to
adjust the flow of traffic to achieve the desired proportionality.

         2.5 IMPLEMENTATION OF MIRROR SITE. eBay shall implement the Mirror
Site subject to the parties' contractual obligations under the AOL Agreements.
ATC acknowledges and agrees that the Mirror Site will be branded with AOL
branding elements as required by the eBay AOL Agreement, that AOL shall have
the exclusive right to sell or offer for sale any advertising inventory for the
Mirror Site and shall retain all revenue derived from any advertising on the
Mirror Site, and that AOL shall have certain rights to place AOL-generated
content on the Mirror Site.

         2.6 NAVIGATION. Except as set forth above, neither party will, in
conjunction with the Co-Branded Pages, use any interstitials, pop-up windows,
other intermediate steps or any other technology or content which acts as a
barrier to the transition of an eBay or ATC User from the eBay Site or ATC Site
to the Co-Branded Pages, nor will a party use any other technology that
interferes with or affects the page layout of such pages. eBay will not
authorize the persons listed in Exhibit D (Persons Not Permitted to Frame the
Co-Branded Pages) to frame the Co-Branded Pages without ATC's express prior
written consent. In addition, eBay will not authorize any person to frame
solely the Co-Branded Pages portion of the eBay Site without ATC's express
prior written consent.

                                       5.
<PAGE>   6

         2.7 ELIGIBLE SERVICES. The parties will mutually agree on the Eligible
Services to be deployed on the Co-Branded Pages. If the parties cannot agree on
a specific vendor or type of Eligible Service, the issue will be escalated for
resolution as set forth in Section 16.1 ("Dispute Resolution"). The parties
have agreed that Saturn Corporation will be a non-exclusive provider of
inspection and warranty services, and that Dependable Auto Shippers will be a
provider of vehicle shipping services, on the Co-Branded Pages. In addition, if
there are services that eBay provides or offers to all eBay Users generally,
regardless of category, then such services may be made available on the
Co-Branded Pages at eBay's sole option.

         2.8 PAGE VIEW ACCOUNTING. eBay will claim the Co-Branded Pages page
views, reach and time spent in its page view counts and other traffic metrics.
As between ATC and eBay, eBay shall be entitled to the page view, reach and
time spent counts with respect to any accounting by any third party page view
auditor (such as Media Metrix).

3.    EBAY RESPONSIBILITIES.

         3.1 CO-BRANDED PAGES OPERATION. eBay will use reasonable commercial
efforts to operate and serve the Co-Branded Pages and Mirror Site in a manner
consistent with the present quality standards of the eBay Site and that meets
response performance standards for eBay Users comparable to those for similar
(in terms of content, proportion of graphics and other high- bandwidth content,
etc.) pages of the eBay Site. Consistent with the Development Schedule, and in
a format mutually agreed to by the parties, eBay will provide ATC with a feed
of all Eligible Vehicle listings then available on the Co-Branded Pages so that
ATC can incorporate such listings into its vehicle search database so that it
may create links to auction detail pages in accordance with the Marketing
Services Agreement.

         3.2 AUCTION HOSTING. eBay will host the auctions of Eligible Vehicles
listed via the Co-Branded Pages or the Mirror Site, subject to eBay's standard
policies and procedures for handling item listings and the AOL Agreements. eBay
shall determine the fees and charges for the listing and sale of any Eligible
Vehicle on the Co-Branded Pages and Mirror Site. eBay agrees that it will not
require ATC Dealers individually or as a group to pay more for a basic level of
service offered on the Co-Branded Pages than eBay charges consumers generally
for such service. eBay may reject or remove the listing for any Eligible
Vehicle if, in eBay's reasonable judgment (a) there is reasonable doubt as to
the accuracy of the listing; (b) ATC or the seller has breached any provision
of the Agreement or the eBay User Agreement, whether because of such listing or
otherwise; (c) there is reasonable doubt as to title, or the right to pass
clear title, to the Eligible Vehicle; or (d) such listing may reasonably be
expected to expose eBay to potential liability or the threat of litigation.
Removal of Eligible Vehicle listings pursuant to this Section shall be grounds
for eBay to immediately terminate the participation of the listing ATC Dealer
on the Co-Branded Pages, the eBay Site and Mirror Site.

         3.3 BILLING. eBay will be responsible for billing and collecting all
amounts due from users of the Co-Branded Pages, and shall bear all of the
credit risk with respect to such amounts. At eBay's request, ATC may invoice
various ATC Dealers on eBay's behalf, but any such invoices will direct the
payor to send payment amounts to a "lockbox" account owned and managed solely
by eBay, where the payee for such invoice will be listed as "AutoTrader
Auctions on eBay" but the name on the account and the Taxpayer ID Number will
be eBay's. It

                                       6.
<PAGE>   7

is currently anticipated that ATC Dealers will ultimately receive two
separate invoices. One invoice will be prepared and delivered by ATC and will
contain all charges unrelated to such ATC Dealers' use of the Co-Branded Pages.
ATC Dealers will also receive a separate, co-branded invoice for charges
relating to such ATC Dealers' use of the Co-Branded Pages (the "CBP Invoice"),
which is expected to be prepared and delivered by eBay or a billing service
provider acting on behalf of eBay. The format and co-branding elements of the
CBP Invoice will be as mutually agreed by the parties. If the parties have
mutually determined that ATC will provide CBP Invoices to ATC Dealers acting as
a contractor of eBay under a separate billing services agreement, such CBP
Invoices will be based on information to be provided by eBay (on a
mutually-agreeable schedule in a mutually-agreeable format). eBay will also
provide billing information in order to permit ATC to coordinate billing
activities with respect to the ATC Dealers. The parties will mutually agree on
an operational specification to implement the above parameters for the billing
process within sixty (60) days after the Effective Date. eBay will use diligent
efforts to implement the specification and to permit the delivery of CBP
Invoices to ATC Dealers directly as rapidly as is commercially feasible, which
in no event will be later than December 31, 2000, unless the delay is caused by
ATC's failure to perform any ATC obligation necessary to allow eBay to
implement the agreed upon billing process. If eBay's diligent efforts are not
sufficient to complete the implementation by December 31, 2000 (or such later
date as is applicable due to any delay caused by ATC), ATC shall have the
right, but not the obligation, to terminate the Agreement pursuant to Section
11.2 ("Termination for Breach"). ATC will inform ATC Dealers and other sellers
that eBay currently offers an electronic billing option for vehicles listed and
sold via the Co-Branded Pages. Finally, to the extent it is legally and
technically feasible and reasonably easy to accomplish, eBay will cause the
line items in credit card bills for charges relating to an ATC Dealer's use of
the Co-Branded Pages to be co-branded in a reasonable period of time.

         3.4 REMOVAL OF CONTENT. ATC reserves the right to require eBay to
remove from the Co-Branded Pages any ATC Content or any eBay Content, as ATC
deems necessary or appropriate if, in ATC's absolute discretion, the
publication of the ATC Content or the eBay Content on the Co-Branded Pages (a)
may create liability for ATC (except for contractual liability, regardless of
whether the applicable contract was entered into by ATC prior to or subsequent
to this Agreement); (b) infringes upon or violates a third party's intellectual
property rights or rights of publicity or privacy; (c) violates any law,
statute, ordinance or regulation; (d) is defamatory, libelous, illegally
threatening or harassing; (e) contains obscenity, pornography or is otherwise
inflammatory; (f) contains a virus or other damaging programming, or (g) in any
way violates this Agreement. In the event that ATC exercises the foregoing
rights to require eBay to remove any eBay Content from the Co-Branded Pages,
ATC will provide eBay prompt written notice of the removal and the basis for
such removal and will cooperate with eBay in remedying the defect that prompted
the request for removal so that the eBay Content that was removed can be
restored to the Co-Branded Pages.

4.   EBAY SITE PROMOTION.

         4.1 GENERAL PROMOTION. Subject to the terms and conditions of this
Agreement (including Sections 2.1 through 2.7) eBay will promote the Co-Branded
Pages by means of a combination of certain fixed, rotating, and other
placements on the eBay Site.

                                       7.
<PAGE>   8

         4.2 FIXED PLACEMENTS. During the Term, eBay will maintain "Automotive"
as a high level category on the homepage of the eBay Site (beginning with the
launch of "Version 1.0" of the general automotive area on the eBay Site). eBay
will provide a one-click text link from the "Automotive" category header on the
eBay Site homepage and will collaborate with ATC regarding the creation and
design of appropriate co-branded Eligible Vehicle-related pages that will be
linked to from the homepage of each U.S. regional site. eBay will provide
additional links to the Co-Branded Pages in the phases specified in the
Development Schedule. If eBay co- brands any other high level category header,
it will brand the "Automotive" category header with ATC branding elements. (For
the purpose of this Section, a "category header" is the key words or phrase,
such as "Automotive" or "Toys, Bean Bag Plush," that links to the start or home
page for the category from the home page of the eBay Site.) The Co-Branded
Pages will contain ATC Marks and other ATC branding elements provided by ATC on
an appropriate and equally comparable footing with eBay Marks and other eBay
branding elements as mutually agreed by the parties. More specifically, each
page of the Co-Branded Pages will have the parties' logos in the top section of
each page, with eBay's Mark to appear in the left corner of the page and ATC's
Mark to appear in the right corner of the page, and one or more text links to
the eBay Site and to the ATC Site, respectively. The ATC logo will link to the
home page of the ATC Site and the eBay logo will link to the home page of the
eBay Site; both logos will be of equal size and prominence. eBay will undertake
to co-brand, in the same manner as other Co-Branded Pages, certain
administrative pages relating to the Co-Branded Pages as follows: (a) eBay will
co-brand all static administrative pages dealing specifically with Eligible
Vehicles and Eligible Services linked to from the Co-Branded Pages (such as
"How to Buy a Car" and "How to Sell a Car" and other pages that have been
revised from their generic form on the eBay site to specifically apply to
Eligible Vehicles); (b) eBay will discuss in good faith and implement in a
reasonable time frame the co-branding of additional frequently-used static
administrative pages linked to from the Co-Branded Pages; and (c) eBay will
discuss in good faith the co-branding of frequently-used dynamic
administrative pages linked to from the Co-Branded Pages and, to the extent
that such co-branding does not require any material commitment of engineering
and product development resources by eBay, implement such mutually-agreed
co-branding in a reasonable time frame.

         4.3 ROTATING PLACEMENTS. The parties further agree that ATC Content
and other promotional materials regarding the Co-Branded Pages may also appear
on one or more mutually-agreeable pages of the eBay Site on a rotating basis
during the Term.

         4.4 ATC "ABOUT ME" PAGE. ATC will develop and eBay will deploy, in
accordance with the Development Schedule (using ATC Content), an informational
"About Me" page for ATC on the Co-Branded Pages and eBay Site in the form of an
HTML page with no links. ATC shall have final editorial control regarding the
ATC "About Me" page, and the parties will cooperate, in accordance with the
Development Schedule, to give eBay adequate time to review and comment on the
proposed "About Me" page before it is made available on the Co-Branded Pages
and eBay Site.

5.   CONSIDERATION.

         5.1 COSTS. Except as set forth in this Agreement, each party shall
bear all of its respective costs in connection with its performance of the
Agreement.

                                 8.
<PAGE>   9

         5.2 EBAY CONSIDERATION. eBay agrees that it will spend a minimum of
Seven Million Dollars ($7,000,000) in calendar year 2000 in arms-length
transactions with independent third parties solely to advertise and promote the
Co-Branded Pages and the products and services available on the Co-Branded
Pages in their own right, Two Million Dollars ($2,000,000), of which will be
spent on offline media placements, and Five Million Dollars ($5,000,000), of
which will be spent on online media placements and general public relations
activities related to the Co-Branded Pages (such as car giveaways). All eBay
promotions targeting Eligible Vehicle auction activities in all media, in
addition to specifically mentioning the Co-Branded Pages, shall use the ATC
branding elements specified by ATC and the eBay branding elements specified by
eBay, and shall be consistent with the messages agreed upon by the parties,
whether or not eBay has already met eBay's minimum spending requirements in
this Section or Section 5.4 ("Subsequent Promotional Activities"). However, if
eBay generally advertises or promotes the eBay Site in a manner which may only
incidentally mention Eligible Vehicles -- such as a "From Beanies to Beetles"
slogan and ad, or a "everything you're looking for in cars" -- no mention of the
Co-Branded Pages or ATC in the advertisement or promotion will be required.
Similarly, if eBay's advertisement or promotion mentions only items which are
not Eligible Vehicles (collector cars, spare parts, etc.), no mention of the
Co-Branded Pages or ATC in the advertisement or promotion will be required. ATC
will have final editorial control over how any of its branding elements and any
ATC Content are used in any eBay advertising and promotions, and eBay will
consult with ATC regarding eBay's overall advertising and promotion strategy
regarding Eligible Vehicle auctions. The parties will cooperate to give ATC
adequate time to review and comment on the proposed advertising and promotional
materials using ATC Marks or ATC Content before they are published or
distributed in any form.

         5.3 ATC CONSIDERATION.

           5.3.1 For Co-Branded Pages development in accordance with Section 3
("eBay Responsibilities") in addition to advertising and promotion delivered in
accordance with Section 4 ("eBay Site Promotion"), ATC will pay eBay a site
promotion fee in accordance with the following table:

                           Eight Million Dollars ($8,000,000), payable in four
                           equal monthly installments beginning in the first

         5.3.2 ATC agrees that it will spend a minimum of Seven Million Dollars
($7,000,000) in calendar year 2000 solely to advertise and promote the
Co-Branded Pages and products and services available on the Co-Branded Pages in
their own right, Five Million Dollars ($5,000,000), of which will be spent on
offline media placements, trade promotions and collateral materials to dealers
and general public relations activities, and Two Million Dollars ($2,000,000),
of which will be spent on online media placements. The parties agree that no
more than Three Hundred Seventy-Five Thousand Dollars ($375,000) of the Five

be allocated to ad placements

                                      10.
<PAGE>   11

in Trader Publishing magazines in calendar year 2000; the parties agree that
the calculation of the value of the ad placements will include a fifty percent
(50%) discount from the national advertising rates applicable to these ad
placements. All ATC promotions of Eligible Vehicle auction activities in all
media, in addition to referencing the Co-Branded Pages, shall use the eBay
branding elements specified by eBay and the ATC branding elements specified by
ATC, and shall be consistent with the messages agreed upon by the parties. eBay
will have final editorial control over how any of its branding elements and any
eBay Content are used in any ATC advertising and promotions, and ATC will
consult with eBay regarding ATC's overall advertising and promotion strategy
regarding Eligible Vehicle auctions. The parties will cooperate to give eBay
adequate time to review and comment on the proposed advertising and promotional
materials using eBay Marks or eBay Content before they are published or
distributed in any form.

         5.4 SUBSEQUENT PROMOTIONAL ACTIVITIES. eBay will spend at least Eight
Million Dollars ($8,000,000) in arms-length transactions with independent third
parties to uniquely promote the Co-Branded Pages and products and services
available thereon in the second year of the Term, Nine Million Dollars
($9,000,000) to do so in the third year of the Term, and Five Million Dollars
($5,000,000) to do so in the final six months of the Term. ATC shall have no
such specific promotional spending obligation after the first year of the Term.

         5.5 COLLABORATION AND JOINT MARKETING EFFORTS. The parties will
collaborate to identify the most efficient venues for their dedicated
promotional spending for the Co-Branded Pages and enhance the impact of their
promotions in appropriate media. The parties will be jointly responsible for
preparing and executing an overall annual advertising and promotion plan for
the Co-Branded Pages that allocates the parties' aggregate dedicated
promotional spending. The parties will also cooperate to develop, fund and
execute joint marketing programs on a mutually-agreeable basis.

         5.6 TAXES.  The parties shall each pay any sales, use or similar tax
related to the parties' performance of their obligations or exercise of their
rights under this Agreement for which they are responsible.

6.    EXCLUSIVE DEALING.

         6.1 RESTRICTIONS ON ATC. Until the earlier of the termination or
expiration of this Agreement or the effective date of a notice of non-renewal
given pursuant to Section 11.1 ("Term"), ATC shall not launch or promote
Competitive Services or establish, enter into, negotiate to establish or enter
into or attempt to implement an agreement or relationship with any other party
to offer, promote or facilitate any such Competitive Services for the U.S.
market, it being understood that ATC running paid advertising by third parties
which does not specifically target person-to-person or business-to-consumer
online trading services (although the advertiser's overall business may
incidentally include such trading services) or Manheim or Trader Publishing
running paid advertising by third parties shall not constitute "promotion" for
the purposes of this Section. Should ATC undertake to develop technology that
would allow it to operate Competitive Services in the U.S. market independent
of eBay, it will immediately notify eBay of such undertaking, and in any case
no later than one (1) week after commencing development.

                                      11.
<PAGE>   12

         6.2 RESTRICTIONS ON EBAY. Until the earlier of the termination or
expiration of this Agreement or the effective date of a notice of non-renewal
given pursuant to Section 11.1 ("Term"), eBay shall not implement any other
site or web pages for the U.S. market for the dynamically priced trading of
Eligible Vehicles, nor shall it discuss, establish, enter into, negotiate to
establish or enter into or attempt to implement an agreement or relationship
with any third party for the dynamically priced trading of Eligible Vehicles
for the U.S. market. eBay may accept listings of Eligible Vehicles for posting
on the Co-Branded Pages that are also listed on other websites or in various
online and offline databases and catalogs, provided that eBay does not create a
co-branded site or set of pages with such listing source for Eligible Vehicles.
Other than listings placed by eBay Users in other categories (which eBay shall
not encourage), or listings posted by Kruse International in the collector car
area of the eBay Site's automotive area, which may contain incidental Eligible
Vehicles (such as a celebrity's car which might otherwise technically fall
within the definition of an Eligible Vehicle), eBay will require that all
Eligible Vehicles on the domestic eBay Site(s) are listed on the Co-Branded
Pages. In addition, until the earlier of the termination or expiration of this
Agreement or the effective date of a notice of non-renewal given pursuant to
Section 11.1 ("Term"), eBay shall not launch or promote any wholesale
automotive auctions for Eligible Vehicles (that is, in any auctions in which
the buyers are required to be registered automobile dealers) or establish,
enter into, negotiate to establish or enter into or attempt to implement an
agreement or relationship with any other party to offer, promote or facilitate
any such wholesale automotive auctions for Eligible Vehicles. The foregoing
restriction does not apply to the remarketing of institutional vehicles from
car manufacturers, finance companies, rental car companies, etc., provided that
eBay does not require that participants in such transactions be licensed
dealers and that such vehicles are listed on the Co-Branded Pages. For purposes
of this Section a relationship will not include a minority investment (i.e.,
less than twenty percent (20%)) by eBay in any company that engages in
activities otherwise precluded under this section as an incidental or ancillary
part of its business.

         6.3 NEW VEHICLES. Nothing in this Agreement shall restrict eBay's
ability to implement any other site or web pages for the trading of new
vehicles, nor prevent eBay from discussing, establishing, entering into,
negotiating to establish or enter into or attempting to implement an agreement
or relationship with any third party for the trading of new vehicles, nor
prevent eBay from launching or promoting any wholesale automotive auctions for
new vehicles.

         7.1 CONTENT LICENSES. eBay hereby grants to ATC a non-exclusive
license to use, reproduce, distribute, create derivative works of, publicly
perform, publicly display and digitally perform the eBay Content in conjunction

<PAGE>   13

suppliers retain all rights, title and interest in and to all intellectual
property rights embodied in or associated with the ATC Content. There are no
implied licenses under this Agreement, and any rights not expressly granted to
a licensee hereunder are reserved by the licensor or its suppliers. Neither
party shall exceed the scope of the licenses granted hereunder.

         7.3 TRADEMARK LICENSE. ATC hereby grants to eBay a non-exclusive
license to use the ATC Marks (a) in links to and advertisements and promotions
for the ATC Site, Eligible Services, Co-Branded Pages and Mirror Site, (b) in
conjunction with hosting and operating the eBay Site, Co-Branded Pages and
Mirror Site, and (c) for the purposes of co-branding emails and other
communications as authorized or required by this Agreement. eBay hereby grants
to ATC a non-exclusive license to use eBay Marks in links to and advertisements
and promotions for the eBay Site, Eligible Services, Co-Branded Pages and
Mirror Site and for the purposes of co-branding emails and other
communications as authorized or required by this Agreement.

         7.4 TRADEMARK RESTRICTIONS. If the Mark owner determines, in its
reasonable discretion, that the licensee's use of the Marks tarnishes, blurs or
dilutes the quality associated with the Marks or the associated goodwill, the
Mark owner may terminate the foregoing license as to the objectionable use if
the licensee does not cease such objectionable use within five (5) days of
notice of breach. Title to and ownership of the owner's Marks shall remain with
the owner. The licensee shall use the Marks exactly in the form provided and in
conformance with any trademark usage policies provided by the Mark owner to the
licensee. The licensee shall not take any action inconsistent with the owner's
ownership of the Marks, and any benefits accruing from use of such Marks shall
automatically vest in and inure to the benefit the owner. The licensee shall
not form any combination marks with the other party's Marks. Notwithstanding
the foregoing, to the extent the URL/domain name ("Domain Name") for the
Co-Branded Pages is deemed a combination mark, neither party shall use the
Domain Name for any purpose except as expressly provided in this Agreement and
the parties shall jointly cooperate in any enforcement action with respect to
infringement of the Domain Name.

         7.5 LIMITS ON SUBLICENSING. All license rights (under any applicable
intellectual property right) granted herein are not sublicenseable,
transferable or assignable, except that eBay may use a third party web hosting
service for the Co-Branded Pages and Mirror Site and ATC may use a third party
web hosting service to host vehicle photographs, and each party shall have the
right to sublicense the other party's Content and Marks solely for such
purpose.

         7.6 CONTENT AND SERVICES STANDARDS. eBay shall not provide any eBay
Content, and ATC shall not provide any ATC Content, that: (a) infringes any
third party's copyright, patent, trademark, trade secret or other proprietary
rights or rights of publicity or privacy; (b) is defamatory, trade libelous,
unlawfully threatening or unlawfully harassing; or (c) is materially false,
misleading or inaccurate. The parties agree that neither party has an
obligation to insure that any user generated content meets these standards.
User-generated content shall be governed by the terms of the eBay User
Agreement.

8.    USER INFORMATION.

         8.1 OWNERSHIP. eBay shall own all User Information, the Page
Templates, and the look and feel and design elements of the Co-Branded Pages
(other than any ATC Content or

                                      13.
<PAGE>   14

ATC Marks or other ATC branding elements) and all intellectual property rights
therein. ATC shall own all information supplied to ATC by ATC Users (other than
feedback rating, feedback profile and other feedback information) or generated
by use of the ATC Site.

         8.2 ATC DEALERS' USER INFORMATION. ATC will request that ATC Dealers
listing Eligible Vehicles on the Co-Branded Pages provide ATC with their eBay
user IDs and give ATC permission to (i) use such user IDs to search the eBay
Site for information about such ATC Dealers' listings and transactions on the
Co-Branded Pages accessible by user ID-based searches; and (ii) have such ATC
Dealers' information required for billing disclosed by eBay to ATC for such
purpose, or as required by applicable law. ATC will provide eBay a list of all
such ATC Dealers' user IDs (updated with whatever frequency is agreed by the
parties), which eBay will use to provide eBay User Information to ATC as
required for billing purposes in accordance with Section 4.5 ("Billing"). eBay
will use good faith efforts throughout the Term to assist ATC in identifying
ATC Dealers and obtaining their user IDs for both parties' use. For example, if
ATC provides eBay with a periodic database feed with the names, addresses and
other relevant information for offline used vehicle dealers with which ATC has
a relationship (an "ATC Dealer List"), eBay will use its good faith efforts to
match this database feed against eBay's database of eBay Users to identify ATC
Dealers and, to the extent permitted by eBay's privacy policies and applicable
law and regulations, communicate with persons so identified who may be ATC
Dealers to confirm their status and obtain permission to disclose their user
IDs to ATC. eBay agrees (a) to only use ATC Dealer Lists provided by ATC in
accordance with this Section solely as required to facilitate billing and the
provision of Eligible Services; and (b) to not disclose any ATC Dealer List
information except as required by law. eBay will not use (nor permit a third
party to use) any ATC Dealer List for any purpose other than to perform its
obligations under this Agreement. eBay shall use at least industry-standard
methods to protect the security of ATC Dealer Lists. eBay hereby grants to ATC
a nonexclusive license solely: (a) to use ATC Dealer User Information provided
by eBay in accordance with this Section as required to facilitate billing and
the provision of Eligible Services; and (b) to disclose User Information as
required by law or the operation of the ATC Site or in aggregate form in a way
that does not disclose discrete items of User Information. ATC will not use
(nor permit a third party to use) User Information for any purpose other than
to perform its obligations under this Agreement. ATC further agrees to use such
User Information only in a manner consistent with ATC's reasonable privacy
policy, such privacy policy to be adequately displayed throughout the ATC Site.
ATC shall use at least industry-standard methods to protect the security of
User Information. ATC represents and warrants that it will not provide eBay
with any ATC Dealer's user ID for the eBay Site without first obtaining the
express written consent of such ATC Dealer for such disclosure to eBay and for
eBay's use of the user ID and eBay's disclosure of such ATC Dealer's User
Information to ATC as permitted in this Agreement and any separate billing
services agreement between eBay and ATC.

         8.3 PROVIDING AGGREGATE INFORMATION TO ATC. On an approximately
monthly basis during the Term once eBay has the required personnel resources (a
data analyst) and to the extent technically feasible, eBay will provide ATC
with a report containing aggregated data ("Aggregate Data") regarding the
operation of the Co-Branded Pages and which would typically be used to analyze
the performance of the Co-Branded Pages. The Aggregate Data will initially
consist of the information listed on Exhibit B (Aggregate User Data), and the
parties will cooperate during the Term to identify additional categories of
mutually-agreeable, relevant

                                      14.
<PAGE>   15

Aggregate Data for inclusion in eBay's reports. All such Aggregate Data is
deemed eBay Confidential Information. eBay hereby grants to ATC a nonexclusive
license solely: (a) to use such Aggregate Data internally to facilitate ATC's
marketing and promotional efforts and for ATC's internal business purposes; and
(b) to disclose Aggregate Data as required by law or to third parties expressly
approved in advance by eBay, in writing, in eBay's sole discretion. ATC shall
use at least industry-standard methods to protect the security of Aggregate
Data.

     8.4 JOINT RESTRICTIONS. ATC will neither use User Information to target
communications to any eBay Users other than ATC Dealers (or facilitate the same
on behalf of third parties) without the express written permission from eBay
and an opt-in agreement from the eBay User, nor will ATC solicit or facilitate
such solicitation by any third party of eBay Users as a result of their status
as eBay Users. Except as set forth in this Section, eBay will not sort its
database of users to extract information solely about eBay Users who are ATC
Dealers and then use such User Information to specifically target such eBay
Users, nor will eBay disclose User Information in such sorted fashion (or in a
way that would allow third parties to do such a sort themselves).

           8.4.1 Each party may target administrative (e.g., not promoting a
third party or self-promoting) messages to eBay Users (including ATC Dealers)
as needed, provided that all such messages regarding Eligible Vehicles shall be
co-branded by each party, as soon as technically feasible based on priorities
set by the parties, such that the parties' respective brands shall appear on an
equal footing.

           8.4.2 Subject to the restrictions imposed by Section 16.4
("Publicity"), eBay may send messages to ATC Dealers during the Term that are
not specifically targeted at them in their identity as ATC Dealers but that are
part of a general communication to a broad range of classes of sellers on the
eBay Site, Co-Branded Pages or Mirror Site.

           8.4.3 Subject to the restrictions imposed by Section 16.4
("Publicity"), ATC may communicate with any ATC Dealer that is also an eBay
User with respect to the ATC Dealer's use of the Co-Branded Pages and (both
during and after the term of the Agreement) with respect to the ATC Dealer's
general relationship with ATC. During the Term, ATC will co-brand such
messages regarding the ATC Dealer's use of the Co-Branded Pages.

9.    REPRESENTATIONS AND WARRANTIES.

         9.1 ATC REPRESENTATIONS. ATC represents and warrants that (a) ATC has
the authority and power to enter into and perform all of its obligations set

Publishing") are parties to agreements with ATC that preclude both Manheim and
Trader Publishing from engaging in any conduct that would be within the scope
of the conduct prohibited by Section 6.1 ("Restrictions on ATC") during the
Term, and that ATC will enforce the provisions of these agreements relating to
the prohibition of such conduct during the Term, it being understood that,
notwithstanding this Section or Section 6.1 ("Restrictions on ATC"), Manheim
shall remain free to conduct online wholesale automobile auctions for
registered dealers and Trader Publishing shall remain free to operate,

performance cars, cars more than twenty (20) years old, motorcycles, or related
equipment, or airplanes, large trucks, heavy equipment, RVs, boats, yachts, or
related equipment, and (ii) any online auction of Eligible Vehicles, so long as

auction of Eligible Vehicles.

         9.2  EBAY REPRESENTATIONS. eBay represents and warrants that eBay has
the authority and power to enter into and perform all of its obligations set

upon any warranty or representation except those specifically set forth herein.

11.    TERM AND TERMINATION.

         11.1 TERM. The term of this Agreement shall continue for three (3)
years and six (6) months following the Effective Date, unless earlier
terminated as provided herein, and shall be automatically renewed for
successive one-year renewal terms (collectively, the "Term"), unless either
party gives the other notice of its desire to terminate the Agreement not less

Co-Branded Pages set forth in Section 1.7 ("Co-Branded Pages") and ATC will

unless eBay terminates this Agreement in accordance with Section 11.2
("Termination for Breach") for a material breach of Sections 5.3.2, 6.1
("Restrictions on ATC"),

                                      16.

in accordance with Sections 2.1 ("Listing Services") or 2.2 ("Search Services")
of the Marketing Services Agreement, eBay shall not solicit, announce, or
promote any vehicle-related products or services to any ATC Dealer for one (1)
year following the date of expiration or termination unless and until any such
ATC Dealer bids on a vehicle offered for sale on the eBay Site or lists a
vehicle for sale on the eBay site, after which eBay may communicate with such
ATC dealer without restriction. For the purposes of clarity, Exhibit C
(Communications Policies) contains examples of permitted and prohibited types
of communication with respect to eBay's vehicle-related products and services.

         11.4 SURVIVAL. In addition to Section 11.3, Sections 1
("Definitions"), 7.2 ("Content Ownership"), 7.4 ("Trademark Restrictions"), 8

Agreement.

12.      INDEMNITY. Each party (the "Indemnifying Party") shall indemnify the
other party (the "Indemnified Party") against any and all claims, losses, costs
and expenses, including reasonable attorneys' fees (collectively, "Claims") as

participate in the defense at its expense.

13.       LIMITATION ON LIABILITY. EXCEPT IN THE EVENT OF A BREACH OF SECTION

OF OR IN ANTICIPATION OF TERMINATION OF THE RELATIONSHIP CONTEMPLATED UNDER THIS
AGREEMENT) OR SECTION 14 ("CONFIDENTIAL INFORMATION") OR A CLAIM UNDER SECTION

PARTY'S CUMULATIVE LIABILITY TO THE OTHER PARTY UNDER OR IN CONNECTION WITH

PROHIBITING COMMUNICATION WITH ATC DEALERS (WHERE SUCH BREACH OCCURS IN THE
WAKE OF OR IN ANTICIPATION OF TERMINATION OF THE RELATIONSHIP CONTEMPLATED
UNDER THIS AGREEMENT), SHALL BE LIMITED TO TWENTY MILLION DOLLARS
($20,000,000), RATHER THAN TO ONE MILLION DOLLARS ($1,000,000). THIS LIMITATION
OF EACH PARTY'S LIABILITY IS CUMULATIVE, WITH ALL PAYMENTS FOR CLAIMS OR
DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE MARKETING SERVICES AGREEMENT
BEING AGGREGATED TO DETERMINE SATISFACTION OF THE LIMIT. THE EXISTENCE OF ONE

14.   CONFIDENTIAL INFORMATION. A party's "Confidential Information" is defined
as any confidential or proprietary information of a party which is disclosed to
the other party in a writing marked confidential or, if disclosed orally, is
identified as confidential at the time of disclosure and is subsequently
reduced to a writing marked confidential and delivered to the other party
within ten (10) days of disclosure, or which, under the circumstances
surrounding disclosure known to the receiving party, ought to be treated as
confidential. Each party shall hold the other party's Confidential Information
in confidence and shall not disclose such Confidential Information to third
parties nor use the other party's Confidential Information for any purpose
other than as required to perform under this Agreement. Such restrictions shall
not apply to Confidential Information which (a) is already known by the
recipient, (b) becomes, through no act or fault of the recipient, publicly
known, (c) is received by recipient from a third party without a restriction on
disclosure or use, or (d) is independently developed by recipient without
reference to the Confidential Information. The restriction on disclosure shall
not apply to Confidential Information that a court or government agency
requires be disclosed. In addition, the parties agree that, as a result of
exposure to Confidential Information relating to the receiving party's business
activities, the employees of the receiving party may further develop their
general knowledge, skills and experience as they relate to the receiving
party's business activities. The subsequent use by these employees of such
general knowledge, skills and experience does not constitute a breach of this
Agreement.

         16.3 SEVERABILITY; HEADINGS. If any provision herein is held to be
invalid or unenforceable for any reason, such provision shall be deemed to be
restated, in accordance with applicable law, to reflect as nearly as possible
the original intentions of the parties, and the remaining provisions will
continue in full force without being impaired or invalidated in any way. The
parties agree to replace any invalid provision with a valid provision that most
closely approximates the intent and economic effect of the invalid provision.
Headings are for reference purposes only and in no way define, limit, construe
or describe the scope or extent of such section.

         16.4 PUBLICITY. Prior to the release of any press releases,
announcements, statements or other similar promotional materials related to
this Agreement, the termination thereof, the Co-Branded Pages, or the status
of the parties' relationship, the releasing party shall submit a written
request for approval to the other party with a copy of the materials to be
released, with sufficient lead time for the other party to review and comment.
A party shall not unreasonably withhold or delay the granting of its approval
of such materials. The parties will cooperate to prepare a joint first public
announcement regarding this Agreement.

hereunder (other than payment of monies due) is prevented, restricted or
interfered with by any act or condition whatsoever beyond the reasonable
control of a party, the party so affected, upon giving prompt notice to the
