                         AMENDMENT TO SECURITY AGREEMENT

         This amendment to security agreement ("Amendment") is made and
entered into as of September 29, 2000 by and between Boats.com, Inc., a
Delaware corporation ("Debtor") and The Cobalt Group, Inc., a Washington
corporation ("Secured Party").

         WHEREAS, Debtor and Secured Party are parties to a Security
Agreement dated as of January 25, 2000 (the "Agreement"; capitalized terms
used herein without definition shall have the meaning set forth in the
Agreement) which Agreement secures Debtor's performance under a promissory
note dated January 25, 2000 (the "Note");

         WHEREAS, Debtor has requested that Secured Party modify the Note, as
set forth in the Note Modification Agreement of even date herewith; and

         WHEREAS, Secured Party wishes to grant Debtor's request subject to
certain terms and conditions, including the amendments outlined below,

         NOW, THEREFORE, for valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto agree as follows:

         1. MAINTAINING SEPARATION OF THE COLLATERAL.  As of the date
hereof, the following new Section 4.8 is hereby added to the Agreement:

             4.8 MAINTAINING SEPARATION OF THE COLLATERAL.  Debtor will:

                 (a)  maintain the segregation, in both hardware and software
                      applications, of the YachtWorld development environment,
                      production environment and databases from other
                      operations of the Debtor; and

                 (b)  prevent interdependencies between the hardware and
                      software of YachtWorld and of the Debtor's other
                      operations, including but not limited to preventing any
                      significant feature of the YachtWorld web site or
                      services from being dependent on accessing data that is
                      part of Debtor's other operations.

                 Debtor will allow the Secured Party to inspect Debtor's
                 operations and question Debtor's employees to ensure
                 compliance with this Section 4.8. Debtor shall have a period
                 of ten days following notice from Secured Party of Debtor's
                 failure to comply with this Section 4.8 to commence measures
                 to remedy the non-compliance; provided, however, that such
                 remedial program must be acceptable to Secured Party. If the
                 parties cannot agree on a remedial program within 10 days, the
                 default will not have been cured and Secured Party may pursue
                 its remedies under this Agreement and under any other statute
                 or agreement;

         2. ACTIONS TO PROTECT COLLATERAL. As of the date hereof, Section 6
of the Agreement is amended to delete the "and" prior to 6(c) and the
following text is added to the end of 6(c):

tax obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined. All elections by an Optionee to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

an Employee with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

         7.       TERM OF PLAN. The Plan shall become effective upon its
adoption by the Board. It shall continue in effect for ten (10) years, unless
sooner terminated under Section 14 of the Plan.

         8.       TERM OF OPTION. The term of each Option shall be stated in the

                  (a)      EXERCISE PRICE. The per share exercise price for the
Shares to be issued pursuant to exercise of an Option shall be determined by the
Administrator.

                  (b)      WAITING PERIOD AND EXERCISE DATES. At the time an
Option is granted, the Administrator shall fix the period within which the
Option may be exercised and shall determine any conditions which must be
satisfied before the Option may be exercised.

                  (c)      FORM OF CONSIDERATION. The Administrator shall
determine the acceptable form of consideration for exercising an Option,
including the method of payment. Such consideration may consist entirely of:

                           (i)      cash;

                           (ii)     check;

                           (iii)    promissory note;

                           (iv)     other Shares which (A) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (B) have a Fair Market Value
on the date of surrender equal to the aggregate exercise price of the Shares as
to which said Option shall be exercised;

                           (v)      consideration received by the Company under
a cashless exercise program implemented by the Company in connection with the
Plan;

                           (vi)     a reduction in the amount of any Company
liability to the Optionee, including any liability attributable to the
Optionee's participation in any Company-sponsored deferred compensation program
or arrangement;

                           (vii)    such other consideration and method of
payment for the issuance of Shares to the extent permitted by Applicable Laws;
or

                           (viii)   any combination of the foregoing methods of
payment.

         10.      EXERCISE OF OPTION.

                  (a)      PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any
Option granted hereunder shall be exercisable according to the terms of the Plan
and at such times and under such conditions as determined by the Administrator
and set forth in the Option Agreement. Unless the Administrator provides
otherwise, vesting of Options granted hereunder shall be tolled during any
unpaid leave of absence. An Option may not be exercised for a fraction of a
Share.

                                      -5-
<PAGE>

                  An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

                  Exercising an Option in any manner shall decrease the number
of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

                  (b)      TERMINATION OF RELATIONSHIP AS AN EMPLOYEE. If an
Optionee ceases to be an Employee, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option Agreement, and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for sixty (60) days following the Optionee's termination. If,
on the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall revert to
the Plan. If, after termination, the Optionee does not exercise his or her
Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                  (c)      DISABILITY OF OPTIONEE. If an Optionee ceases to be
an Employee as a result of the Optionee's Disability, the Optionee may exercise
his or her Option within such period of time as is specified in the Option
Agreement, to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

                  (d)      DEATH OF OPTIONEE. If an Optionee dies while an
Employee, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only

                                      -6-
<PAGE>

to the extent that the Option is vested on the date of death. In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for twelve (12) months following the Optionee's termination. If, at the time of
death, the Optionee is not vested as to his or her entire Option, the Shares
covered by the unvested portion of the Option shall immediately revert to the
Plan. The Option may be exercised by the executor or administrator of the
Optionee's estate or, if none, by the person(s) entitled to exercise the Option
under the Optionee's will or the laws of descent or distribution. If the Option
is not so exercised within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                  (e)      BUYOUT PROVISIONS. The Administrator may at any time
offer to buy out for a payment in cash or Shares, an Option previously granted
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         11.      NON-TRANSFERABILITY OF OPTIONS. Unless determined otherwise by
the Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

         12.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION,
MERGER OR ASSET SALE.

                  (a)      CHANGES IN CAPITALIZATION. Subject to any required
action by the shareholders of the Company, the number of shares of Common Stock
covered by each outstanding Option, and the number of shares of Common Stock
which have been authorized for issuance under the Plan but as to which no
Options have yet been granted or which have been returned to the Plan upon
cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; PROVIDED, HOWEVER, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

                  (b)      DISSOLUTION OR LIQUIDATION. In the event of the
proposed dissolution or liquidation of the Company, the Administrator shall
notify each Optionee as soon as practicable prior to the effective date of such
proposed transaction. The Administrator in its discretion may provide for an
Optionee to have the right to exercise his or her Option until ten (10) days
prior to such transaction as to all of the Optioned Stock covered thereby,
including Shares as to which the Option would not otherwise be exercisable. In
addition, the Administrator may provide that any Company repurchase option
applicable to any Shares purchased upon exercise of an Option shall lapse as to
all

                                      -7-
<PAGE>

such Shares, provided the proposed dissolution or liquidation takes place at the
time and in the manner contemplated. To the extent it has not been previously
exercised, an Option will terminate immediately prior to the consummation of
such proposed action.

                  (c)      MERGER OR ASSET SALE. In the event of a merger of the
Company with or into another corporation, or the sale of substantially all of
the assets of the Company, each outstanding Option shall be assumed or an
equivalent option or right substituted by the successor corporation or a Parent
or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option, the Optionee shall
fully vest in and have the right to exercise the Option as to all of the
Optioned Stock, including Shares as to which it would not otherwise be vested or
exercisable. If an Option becomes fully vested and exercisable in lieu of
assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option shall be fully vested and exercisable for a period of fifteen (15) days
from the date of such notice, and the Option shall terminate upon the expiration
of such period. For the purposes of this paragraph, the Option shall be
considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned
Stock, immediately prior to the merger or sale of assets, the consideration
(whether stock, cash, or other securities or property) received in the merger or
sale of assets by holders of Common Stock for each Share held on the effective
date of the transaction (and if holders were offered a choice of consideration,
the type of consideration chosen by the holders of a majority of the outstanding
Shares); PROVIDED, HOWEVER, that if such consideration received in the merger or
sale of assets is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option,
for each Share of Optioned Stock to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

         13.      DATE OF GRANT. The date of grant of an Option shall be, for
all purposes, the date on which the Administrator makes the determination
granting such Option, or such other later date as is determined by the
Administrator. Notice of the determination shall be provided to each Optionee
within a reasonable time after the date of such grant.

         14.      AMENDMENT AND TERMINATION OF THE PLAN.

                  (a)      AMENDMENT AND TERMINATION. The Board may at any time
amend, alter, suspend or terminate the Plan.

                  (b)      EFFECT OF AMENDMENT OR TERMINATION. No amendment,
alteration, suspension or termination of the Plan shall impair the rights of any
Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company. Termination of the Plan shall not affect the Administrator's
ability to exercise the powers granted to it hereunder with respect to options
granted under the Plan prior to the date of such termination.

                                      -8-

         15.      CONDITIONS UPON ISSUANCE OF SHARES.

                  (a)      LEGAL COMPLIANCE. Shares shall not be issued pursuant
to the exercise of an Option unless the exercise of such Option and the issuance
and delivery of such Shares shall comply with Applicable Laws and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

                  (b)      INVESTMENT REPRESENTATIONS. As a condition to the
exercise of an Option the Company may require the person exercising such Option
to represent and warrant at the time of any such exercise that the Shares are
being purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

         16.      INABILITY TO OBTAIN AUTHORITY. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

         17.      RESERVATION OF SHARES. The Company, during the term of this
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

II.      AGREEMENT

         1.       GRANT OF OPTION. The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to
Section 14(b) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

         2.       EXERCISE OF OPTION.

                  (a)      RIGHT TO EXERCISE. This Option is exercisable during
its term in accordance with the Vesting Schedule set out in the Notice of Grant
and the applicable provisions of the Plan and this Option Agreement.

                  (b)      METHOD OF EXERCISE. This Option is exercisable by
delivery of an exercise notice, in the form attached as Exhibit A (the "Exercise
Notice"), which shall state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the "Exercised
Shares"), and such other representations and agreements as may be required by
the Company pursuant to the provisions of the Plan. The Exercise Notice shall be
completed by the Optionee and delivered to Stock Option Administrator. The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares. This Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.

                   No Shares shall be issued pursuant to the exercise of this
Option unless such issuance and exercise complies with Applicable Laws. Assuming
such compliance, for income tax purposes the Exercised Shares shall be
considered transferred to the Optionee on the date the Option is exercised with
respect to such Exercised Shares.

         3.       METHOD OF PAYMENT. Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the election of
the Optionee:

                  (a)      cash;

                  (b)      check;

                  (c)      consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan; or

                  (d)      surrender of other Shares which (i) in the case of
Shares acquired upon exercise of an option, have been owned by the Optionee for
more than six (6) months on the date of surrender, AND (ii) have a Fair Market
Value on the date of surrender equal to the aggregate Exercise Price of the
Exercised Shares.

                                      -2-
<PAGE>

         4.       NON-TRANSFERABILITY OF OPTION. This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by the
Optionee. The terms of the Plan and this Option Agreement shall be binding upon
the executors, administrators, heirs, successors and assigns of the Optionee.

         5.       TERM OF OPTION. This Option may be exercised only within the
term set out in the Notice of Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option Agreement.

         6.       TAX CONSEQUENCES. Some of the federal tax consequences
relating to this Option, as of the date of this Option, are set forth below.
THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE
SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

                  (a)      EXERCISING THE OPTION. The Optionee may incur regular
federal income tax liability upon exercise of an NSO. The Optionee will be
treated as having received compensation income (taxable at ordinary income tax
rates) equal to the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price. If the
Optionee is an Employee or a former Employee, the Company will be required to
withhold from his or her compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

                  (b)      DISPOSITION OF SHARES. If the Optionee holds NSO
Shares for at least one year, any gain realized on disposition of the Shares
will be treated as long-term capital gain for federal income tax purposes.

         7.       ENTIRE AGREEMENT; GOVERNING LAW. The Plan is incorporated
herein by reference. The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee. This agreement is governed by the internal substantive
laws, but not the choice of law rules, of California.

         8.       NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND
AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS
EARNED ONLY BY CONTINUING AS AN EMPLOYEE AT THE WILL OF THE COMPANY (AND NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES
HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS AN
EMPLOYEE FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND

                                      -3-
<PAGE>

SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
OPTIONEE'S RELATIONSHIP AS AN EMPLOYEE AT ANY TIME, WITH OR WITHOUT CAUSE.

         By your signature and the signature of the Company's representative
below, you and the Company agree that this Option is granted under and governed
by the terms and conditions of the Plan and this Option Agreement. Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Option Agreement. Optionee further agrees to notify the Company upon any
change in the residence address indicated below.
