                           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

                                    AutoTrader site composed by AutoTrader and
                                    sent to the Registered Users List. Each
                                    newsletter will contain up to four
                                    AutoTrader partner messages. Partner

                                    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)

                                    message. In the event that Greenlight
                                    participates in any such newsletter,
                                    Greenlight shall pay AutoTrader the

                                    generated by Greenlight's purchase of the
                                    right to send e-mails to the Registered
                                    Users List and Greenlight's participation in
                                    any AutoTrader newsletter e-mails will count
                                    toward the bonus traffic targets outlined in
                                    Section 3.4.

day of the following calendar month.

                           (c)      In connection with the fees set forth in
Sections 3.1(a) and (b) above, following the commencement of Phase II,
AutoTrader will guarantee 30,000 Click-Throughs per calendar month to the

shortfall" means that AutoTrader shall have delivered 100% of the Click-Throughs
due for following calendar month, plus additional Click-Throughs in an amount
equal to the number of Click-Throughs which AutoTrader failed to deliver during

numbers. If Greenlight's and AutoTrader's numbers are not within 5% of each
other, each party shall have 30 days to review its tracking methods and propose
new numbers. If at the end of 30 days the numbers still differ by more than 5%,

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
during which the applicable period of AutoTrader's performance is not a complete
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.

                  3.2      Advertising Fees.

                  (a)      In consideration for AutoTrader's performance of its

in the following month (in addition to the amounts set forth in this Agreement).

                  (b)      For purposes of this Section 3.2, in the event that
the Term of this Agreement ends on other than the last day of a calendar month,
the advertising fee and guaranteed number of Greenlight impressions for such
final 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
final calendar month.

                  3.3      Referral Quality Bonus. Greenlight agrees to pay
AutoTrader a bonus of Five Thousand Dollars ($5,000) for every 100 vehicles it
sells to users initially reaching the Greenlight Site through any Click-Throughs
