THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT
AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"1933 ACT") OR ANY STATE SECURITIES LAWS.  SUCH SECURITIES MAY NOT BE SOLD OR
TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER
THE 1933 ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

                       WARRANT TO PURCHASE 10,000 SHARES
                             OF THE COMMON STOCK OF
                              CarsDirect.com, Inc.
                           (Void after July 19, 2006)

     This certifies that Heidrick & Struggles, Inc. or its assigns (each
individually, the "Holder") for value received, shall be entitled to purchase
from CarsDirect.com, Inc. a Delaware corporation (the "Company"), having its
principal place of business at 4312 Woodman Avenue, Third Floor, Sherman Oaks,
CA 91423, a maximum of 10,000 fully paid and nonassessable shares of the
Company's Common Stock ("Common Stock") for cash at a price equal to $0.35 per
share (the "Exercise Price") at any time, or from time to time, up to and
including 5:00 p.m. (local time) on the seventh anniversary from the date of
this Warrant (the "Expiration Date"), upon the surrender to the Company at its
principal place of business (or at such other location as the Company may advise
the Holder in writing) of this Warrant properly endorsed a Form of Subscription
in substantially the form attached hereto duly filled in and signed and, if
applicable, upon payment in cash or by check of the aggregate Exercise Price for
the number of shares for which this Warrant is being exercised determined in
accordance with the provisions hereof.  The Exercise Price and the number of
shares of Common Stock purchasable hereunder are subject to adjustment as
provided in Section 3 of this Warrant.

     This Warrant is subject to the following terms and conditions:

     1.  Exercise; Issuance of Certificates; Payment for Shares.

         1.1  General.  This Warrant is exercisable at the option of the holder
of record hereof at any time or from time, to time, up to the Expiration Date
for all or any part of the shares of Common Stock (but not for a fraction of a
share) which may be purchased hereunder. The Company agrees that the shares of
Common Stock purchased under this Warrant shall be and are deemed to be issued
to the Holder hereof as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been surrendered, properly
endorsed, the completed, executed Form of Subscription delivered and payment
made for such shares. Certificates for the shares of Common Stock so purchased,
together with any other securities or property to which the Holder is entitled
upon such exercise, shall be delivered to the Holder by the Company at the
Company's expense within a reasonable time after the rights represented by this
Warrant have been so exercised, and in any event, within fifteen (15) days of
such exercise. In case of a purchase of less than all the shares which may be
purchased under this Warrant, the Company shall cancel this Warrant and execute
and deliver a new Warrant or Warrants of like tenor for the balance of the
shares purchasable under the Warrant surrendered upon such purchase to the
Holder hereof within a reasonable time. Each stock certificate so delivered
shall
<PAGE>

be in such denominations of Common Stock as may be requested by the Holder
hereof and shall be registered in the name designated by such Holder.

     1.2  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 this Warrant for cash, the Holder may elect to receive
shares equal to the value (as determined below) of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant at the principal office of
the Company together with the properly endorsed Form of Subscription and notice
of such election in which event the Company shall issue to the 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 Holder

                             Y =  the number of shares of Common Stock
                             purchasable under the Warrant or, if only a portion
                             of the Warrant is being exercised, the portion of
                             the Warrant 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)

                             B =  Exercise Price (as adjusted to the date of
                             such calculation).

For purposes of the above calculation, the fair market value of one share of
Common Stock shall be determined by the Company's Board of Directors in good
faith; provided, however, that where there is a public market for the Company's
Common Stock, the fair market value per share shall be the average of the
closing prices of the Company's Common Stock quoted on the Nasdaq National
Market (or similar system) or on any exchange on which the Common Stock is
listed, whichever is applicable, over the five (5) day period ending one (1) day
before the day the current fair market value is being determined.

     2.  Shares to be Fully Paid; Reservation of Shares.  The Company covenants
and agrees that all shares of Common Stock which may be issued upon the exercise
of the rights represented by this Warrant will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any shareholder and free of all taxes, liens and charges
with respect to the issue thereof. The Company further covenants and agrees
that, during the period within which the rights represented by this Warrant may
be exercised, the Company will at all times have authorized and reserved, for
the purpose of issue or transfer upon exercise of the subscription rights
evidenced by this Warrant, a sufficient number of shares of authorized but
unissued Common Stock, or other securities and property, when and as required to
provide for the exercise of the rights represented by this Warrant. The Company
will take all such action as may be necessary to assure that such shares of
Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange upon which the Common Stock may be listed;

                                       2.
<PAGE>

provided, however, that the Company shall not be required to effect a
registration under Federal or State securities laws with respect to such
exercise. The Company will not take any action which would result in any
adjustment of the Exercise Price (as set forth in Section 3 hereof) if the total
number of shares of Common Stock issuable after such action upon exercise of all
outstanding warrants, together with all shares of Common Stock then outstanding
and all shares of Common Stock then issuable upon exercise of all options and
upon the conversion of all convertible securities then outstanding, would exceed
the total number of shares of Common Stock then authorized by the Company's
Articles/Certificate of Incorporation (the "Company Charter").

     3.  Adjustment of Exercise Price and Number of Shares.  The Exercise Price
and the number of shares purchasable upon the exercise of this Warrant shall be
subject to adjustment from time to time upon the occurrence of certain events
described in this Section 3. Upon each adjustment of the Exercise Price, the
Holder of this Warrant shall thereafter be entitled to purchase, at the Exercise
Price resulting from such adjustment, the number of shares obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of shares purchasable pursuant hereto immediately prior to such
adjustment, and dividing the product thereof by the Exercise Price resulting
from such adjustment.

         3.1  Subdivision or Combination of Stock.  In case the Company shall at
any time subdivide its outstanding shares of Common Stock 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 Common Stock of the Company shall be combined into a smaller number of
shares, the Exercise Price in effect immediately prior to such combination shall
be proportionately increased.

         3.2  Dividends in Common Stock, Other Stock, Property,
Reclassification. If at any time or from time to time the Holders of Common
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor,

              (a)  Common Stock or any shares of stock or other securities which
are at any time directly or indirectly convertible into or exchangeable for
Common Stock, or any rights or options to subscribe for, purchase or otherwise
acquire any of the foregoing by way of dividend or other distribution,

              (b)  any cash paid or payable otherwise than as a cash dividend,
or

              (c)  Common Stock or additional stock or other securities or
property (including cash) by way of spinoff, split-up, reclassification,
combination of shares or similar corporate rearrangement, (other than shares of
Common Stock issued as a stock split or adjustments in respect of which shall be
covered by the terms of Section 3.1 above), then and in each such case, the
Holder hereof shall, upon the exercise of this Warrant, be entitled to receive,
in addition to the number of shares of Common Stock receivable thereupon, and
without payment of any additional consideration therefor, the amount of stock
and other securities and property (including cash in the cases referred to in
clause (b) above and this clause (c)) which such Holder would hold on the date
of such exercise had he been the holder of record of such

                                       3.
<PAGE>

Common Stock as of the date on which holders of Common Stock received or became
entitled to receive such shares or all other additional stock and other
securities and property.

     3.3  Reorganization, Reclassification, Consolidation, Merger or Sale.  If
any recapitalization, reclassification or reorganization of the capital stock of
the Company, or any consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets or other
transaction shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities, or other assets or property (an
"Organic Change"), then, as a condition of such Organic Change, lawful and
adequate provisions shall be made by the Company whereby the Holder hereof shall
thereafter have the right to purchase and receive (in lieu of the shares of the
Common Stock of the Company immediately theretofore purchasable and receivable
upon the exercise of the rights represented by this Warrant) such shares of
stock, securities or other assets or property as may be issued or payable with
respect to or in exchange for a number of outstanding shares of such Common
Stock equal to the number of shares of such stock immediately theretofore
purchasable and receivable upon the exercise of the rights represented by this
Warrant. In the event of any Organic Change, appropriate provision shall be made
by the Company with respect to the rights and interests of the Holder of this
Warrant to the end that the provisions hereof (including, without limitation,
provisions for adjustments of the Exercise Price and of the number of shares
purchasable and receivable upon the exercise of this Warrant) shall thereafter
be applicable, in relation to any shares of stock, securities or assets
thereafter deliverable upon the exercise hereof. The Company will not effect any
such consolidation, merger or sale unless, prior to the consummation thereof,
the successor corporation (if other than the Company) resulting from such
consolidation or the corporation purchasing such assets shall assume by written
instrument reasonably satisfactory in form and substance to the Holders executed
and mailed or delivered to the registered Holder hereof at the last address of
such Holder appearing on the books of the Company, the obligation to deliver to
such Holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such Holder may be entitled to purchase.

     3.4  Certain Events.  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 3 are not strictly applicable or if strictly applicable would not fairly
protect the purchase rights of the Holder of the Warrant in accordance with such
provisions, then the Board of Directors of the Company shall make an adjustment
in the number and class of shares available under the Warrant, the Exercise
Price or the application of such provisions, so as to protect such purchase
rights as aforesaid.  The adjustment shall be such as will give the Holder of
the Warrant upon exercise for the same aggregate Exercise Price the total
number, class and kind of shares as he would have owned had the Warrant been
exercised prior to the event and had he continued to hold such shares until
after the event requiring adjustment.

                                       4.
<PAGE>

     3.5  Notices of Change.

          (a)  If prior to an initial public offering, promptly following any
adjustment in the number or class of shares subject to this Warrant and of the
Exercise Price, the Company shall give written notice thereof to the Holder,
setting forth in reasonable detail and certifying the calculation of such
adjustment.

          (b)  If prior to an initial public offering, the Company shall give
written notice to the Holder at least 10 business 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.

          (c)  If prior to an initial public offering, the Company shall also
give written notice to the Holder at least 30 business days prior to the date on
which an Organic Change shall take place.

     4.  Issue Tax.  The issuance of certificates for shares of Common Stock
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax (other than any applicable income taxes) in
respect thereof; provided, however, that the Company shall not be required to
pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the then
Holder of the Warrant being exercised.

     5.  Closing of Books.  Subject to federal and state securities laws, the
Company will at no time close its transfer books against the transfer of any
warrant or of any shares of Common Stock issued or issuable upon the exercise of
any warrant in any manner which interferes with the timely exercise of this
Warrant.

     6.  No Voting or Dividend Rights; Limitation of Liability.  Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent or to receive notice as a shareholder of
the Company or any other matters or any rights whatsoever as a shareholder of
the Company. No dividends or interest shall be payable or accrued in respect of
this Warrant or the interest represented hereby or the shares purchasable
hereunder until, and only to the extent that, this Warrant shall have been
exercised. No provisions hereof, in the absence of affirmative action by the
holder to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the holder hereof, shall give rise to any liability of
such Holder for the Exercise Price or as a shareholder of the Company, whether
such liability is asserted by the Company or by its creditors.

     7.  Warrants Transferable.  Subject to compliance with applicable federal
and state securities laws, this Warrant and all rights hereunder are
transferable, in whole or in part, without charge to the holder hereof (except
for transfer taxes), upon surrender of this Warrant properly endorsed. Each
taker and holder of this Warrant, by taking or holding the same, consents and
agrees that this Warrant, when endorsed in blank, shall be deemed negotiable,
and that the holder hereof, when this Warrant shall have been so endorsed, may
be treated by the Company, at the Company's option, and all other persons
dealing with this Warrant as the absolute owner hereof for any purpose and as
the person entitled to exercise the rights represented by this Warrant, or to
the transfer hereof on the books of the Company any notice to the contrary
notwithstanding; but until such transfer on such books, the Company may treat
the registered owner hereof as the owner for all purposes.

                                       5.
<PAGE>

     8.  Rights and Obligations Survive Exercise of Warrant.  The rights and
obligations of the Company, of the holder of this Warrant and of the holder of
shares of Common Stock issued upon exercise of this Warrant, shall survive the
exercise of this Warrant.

     9.  Further Representations, Warranties and Covenants of the Company.

         (a)  Articles and Bylaws.  The Company has made available to Holder
true, complete and correct copies of the Company Charter and Bylaws, as amended,
through the date hereof.

         (b)  Due Authority.  The execution and delivery by the Company of this
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire the shares of Common
Stock, have been duly authorized by all necessary corporate action on the part
of the Company, and the Warrant is not inconsistent with the Company Charter or
Bylaws and constitutes a legal, valid and binding agreement of the Company,
enforceable in accordance with its terms.

         (c)  Consents and Approvals.  No consent or approval of, giving of
notice to, registration with, or taking of any other action in respect of any
state, federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for any filing required by applicable
federal and state securities laws, which filing will be effective by the time
required thereby.

         (d)  Issued Securities.  All issued and outstanding shares of capital
stock of the Company have been duly authorized and validly issued and are fully
paid and nonassessable. All outstanding shares of capital stock were issued in
full compliance with all federal and state securities laws.

         (e)  Exempt Transaction.  Subject to the accuracy of the Holders
representations in Section 10 hereof, the issuance of the Common Stock upon
exercise of this Warrant will constitute a transaction exempt from the
registration requirements of Section 5 of the Securities Act of 1933, as amended
(the "1933 Act"), in reliance upon Section 4(2) thereof.

         (f)  Compliance with Rule 144.  At the written request of the Holder,
     who proposes to sell Common Stock issuable upon the exercise of the Warrant
     in compliance with Rule 144 promulgated by the Securities and Exchange
     Commission, the Company shall furnish to the Holder, within thirty (30)
     days after receipt of such request, a written statement confirming the
     status of the Company's compliance with the filing requirements of the
     Securities and Exchange Commission as set forth in such Rule, as such Rule
     may be amended from time to time.

                                       6.
<PAGE>

     10.  Representations and Covenants of the Holder.

     This Warrant has been entered into by the Company in reliance upon the
following representations and covenants of the Holder:

         (a)  Investment Purpose.  The Warrant or the Common Stock issuable upon
exercise of the Warrant will be acquired for investment and not with a view to
the sale or distribution of any part thereof, and the Holder has no present
intention of selling or engaging in any public distribution of the same except
pursuant to a registration or exemption.

         (b)  Private Issue.  The Holder understands (i) that the Warrant and
the Common Stock issuable upon exercise of this Warrant is not registered under
the 1933 Act or qualified under applicable state securities laws on the ground
that the issuance contemplated by this Warrant will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

         (c)  Disposition of Holders Rights.  In no event will the Holder make a
disposition of the Warrant or the Common Stock issuable upon exercise of the
Warrant unless and until (i) it shall have notified the Company of the proposed
disposition, and (ii) if requested by the Company, it shall have furnished the
Company with an opinion of counsel (which counsel may either be inside or
outside counsel to the Holder) satisfactory to the Company and its counsel to
the effect that (A) appropriate action necessary for compliance with the 1933
Act and state securities laws has been taken, or (B) an exemption from the
registration requirements of the 1933 Act and state securities laws is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Common Stock or Common Stock
issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Common Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. Whenever the restrictions
imposed hereunder shall terminate, as hereinabove provided, the Holder or holder
of a share of Common Stock then outstanding as to which such restrictions have
terminated shall be entitled to receive from the Company, without expense to
such holder, one or more new certificates for the Warrant or for such shares of
Common Stock not bearing any restrictive legend.

     (d)  Financial Risk.  The Holder 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 bear the economic risks of its
investment.

                                       7.
<PAGE>

     (e)  Risk of No Registration.  The Holder understands that if the Company
does not register with the Securities and Exchange Commission pursuant to
Section 12 of the 1933 Act, or file reports pursuant to Section 15(d), of the
Securities Exchange Act of 1934 (the "1934 Act"), or if a registration statement
covering the securities under the 1933 Act is not in effect when it desires to
sell (i) the Warrant, or (ii) the Common Stock issuable upon exercise of the
Warrant, it may be required to hold such securities for an indefinite period.
The Holder also understands that any sale of the Warrant or the Common Stock
issuable upon exercise of the Warrant which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f)  Accredited Investor.  Holder is an "accredited investor" within the
meaning of Rule 501 of Regulation D under the 1933 Act, as presently in effect.

     11.  Modification and Waiver.  This Warrant and any provision hereof may be
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of the same is sought.

     12.  Notices.  Any notice, request or other document required or permitted
to be given or delivered to the holder hereof or the Company shall be delivered
or shall be sent by certified mail, postage prepaid, to each such holder at its
address as shown on the books of the Company or to the Company at the address
indicated therefor in the first paragraph of this Warrant or such other address
as either may from time to time provide to the other.

     13.  Binding Effect on Successors.  This Warrant shall be binding upon any
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets.  All of the obligations of the
Company relating to the Common Stock issuable upon the exercise of this Warrant
shall survive the exercise and termination of this Warrant.  All of the
covenants and agreements of the Company shall inure to the benefit of the
successors and assigns of the holder hereof.

     14.  Descriptive Headings and Governing Law.  The description headings of
the several sections and paragraphs of this Warrant are inserted for convenience
only and do not constitute a part of this Warrant. This Warrant shall be
construed and enforced in accordance with, and the rights of the parties shall
be governed by, the laws of the State of California.

     15.  Lost Warrants.  The Company represents and warrants to the Holder
hereof that upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction, or mutilation of this Warrant and, in the case of
any such loss, theft or destruction, upon receipt of an indemnity reasonably
satisfactory to the Company, or in the case of any such mutilation upon
surrender and cancellation of such Warrant, the Company, at its expense, will
make and deliver a new Warrant, of like tenor, in lieu of the lost, stolen,
destroyed or mutilated Warrant.

     16.  Fractional Shares.  No fractional shares shall be issued upon exercise
of this Warrant. The Company shall, in lieu of issuing any fractional share, pay
the holder entitled to such fraction a sum in cash equal to such fraction
multiplied by the then effective Exercise Price.

                                       8.

                                                                -------------
and the "Purchase Price," respectively. This Warrant is issued in connection
         --------------
with the transactions described in that certain Master Agreement dated as of May

     1.   Exercise.
          --------

          (a)  This Warrant may be exercised by the Holder, in whole or in part,
by surrendering this Warrant, with the purchase form appended hereto as Exhibit
                                                                        -------
A duly executed by such Holder or by such Holder's duly authorized attorney, at
-
the principal office of the Company, or at such other office or agency as the
Company may designate, accompanied by payment in full by cash, check or wire
transfer of the Purchase Price payable in respect of the number of shares of
Warrant Stock purchased upon such exercise.
<PAGE>

          (b)  Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered to the Company as provided in Section 1(a)
above. At such time, the person or persons in whose name or names any
certificates for Warrant Stock shall be issuable upon such exercise shall be
deemed to have become the holder or holders of record of the Warrant Stock
represented by such certificates.

          (c)  Net Issue Exercise.

               (i)  In lieu of exercising this Warrant in the manner provided
above in Section 1(a), the Holder may elect to receive shares equal to the value
of this Warrant (or the portion thereof being canceled) by surrender of this
Warrant at the principal office of the Company together with notice of such
election in which event the Company shall issue to Holder a number of shares of
Warrant Stock computed using the following formula:

          X = Y (A - B)
              ---------
                  A

Where     X = The number of shares of Warrant Stock to be issued to the Holder.

          Y = The number of shares of Warrant Stock purchasable under this
Warrant (at the date of such calculation).

          A = The fair market value of one share of Warrant Stock (at the date
of such calculation).

          B = The Purchase Price (as adjusted to the date of such calculation).

               (ii) For purposes of this Section 1(c), the fair market value of
each share of Warrant Stock shall be: (a) if Warrant Stock is traded in the
public market, the closing price of Warrant Stock reported for the business day
immediately before this Warrant is exercised (or the average of the closing bid
and ask if Warrant Stock is traded in the over-the-counter market); (b) if
securities into which Warrant Stock is convertible are traded on the public
market, the closing price of such securities (or the average of the closing bid
and ask if such securities are traded in the over-the-counter market) multiplied
by the number of shares of such securities into which each share of Warrant
Stock is convertible; and (c) if neither Warrant Stock nor any security into
which Warrant Stock is convertible is traded in the public market, the fair
market value as determined by the Board of Directors in its reasonable good
faith judgment.

          (d)  As soon as practicable after the exercise of this Warrant in full
or in part, and in any event within 15 days thereafter, the Company at the
Company's expense will cause to be issued in the name of, and delivered to, the
Holder, or as such Holder (upon payment by such Holder of any applicable
transfer taxes) may direct:

                                      -2-
<PAGE>

               (i)  a certificate or certificates for the number of shares of
Warrant Stock to which such Holder shall be entitled, and

               (ii) in case such exercise is in part only, a new warrant or
warrants (dated the date hereof) of like tenor, providing in the aggregate for
the number of shares of Warrant Stock equal (without giving effect to any
adjustment therein) to the number of such shares provided for in this Warrant
minus the number of such shares purchased by the Holder upon such exercise as
provided in Section 1(a) or 1(c) above.

     2.   Adjustments.
          -----------

          (a)  If outstanding shares of the Company's Common Stock shall be
subdivided into a greater number of shares or a stock dividend shall be paid in
respect of Common Stock, the Purchase Price in effect immediately prior to such
subdivision or at the record date of such dividend, as the case may be, shall
simultaneously with the effectiveness of such subdivision or immediately after
the record date of such dividend be proportionately reduced. If outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Purchase Price in effect immediately prior to such combination shall,
simultaneously with the effectiveness of such combination, be proportionately
increased. When any adjustment is required to be made in the Purchase Price, the
number of shares of Warrant Stock purchasable upon the exercise of this Warrant
shall be changed to the number determined by dividing (i) an amount equal to the
number of shares issuable upon the exercise of this Warrant immediately prior to
such adjustment, multiplied by the Purchase Price in effect immediately prior to
such adjustment, by (ii) the Purchase Price in effect immediately after such
adjustment.

          (b)  In case of any reclassification or change of the outstanding
securities of the Company or of any reorganization of the Company on or after
the date hereof, other than an event described in Section 2(c), then and in each
such case the Holder of this Warrant, upon the exercise hereof at any time after
the consummation of such reclassification, change, or reorganization, shall be
entitled to receive, in lieu of the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities or property to which such Holder would have been entitled upon
such consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in paragraph (a); and in
each such case, the terms of this Section 2 shall be applicable to the shares of
stock or other securities properly receivable upon the exercise of this Warrant
after such consummation.

          (c)  If at any time there shall be a merger or consolidation of the
Company with or into another corporation pursuant to which the stockholders of
the Company immediately prior to such merger or consolidation control less than
50% of the voting securities of the surviving corporation, or the sale of all or
substantially all of the assets of the Company shall be affected in such a way
that holders of the Company Common Stock shall be entitled to receive stock,
securities or assets with respect to or in exchange for the Company Common
Stock, then, as a part of such merger, consolidation or sale, lawful provision
shall be made so that the holder of this Warrant shall thereafter be entitled to
receive upon exercise of this Warrant and upon payment of the aggregate

                                      -3-
<PAGE>

exercise price then in effect the number of shares of stock or other securities
or property resulting from such merger, consolidation or sale to which a holder
of the stock deliverable upon exercise of this Warrant would have been entitled
in such merger, consolidation or sale if this Warrant had been exercised
immediately before such merger, consolidation or sale. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Warrant with respect to the rights and interests of the Holder after the
merger, consolidation or sale. Notwithstanding the provisions of this Section
2(c) to the contrary, (1) the Holder shall be required to exercise this Warrant
prior to any such merger, consolidation or sale (x) if and to the extent such
exercise and the holding of the property received upon such exercise would not
cause the Holder to be in violation of any laws applicable to national banks and
(y) if and to the extent the corporation or other entity that is party to the
transaction described in this Section 2(c) other than the Company notifies the
Company and the Holder in writing at least 10 days before the consummation of
said transaction of its demand for the Holder to exercise all or a portion of
the Warrant, and (2) the preceding two sentences shall apply only to that
portion of this Warrant as to which the Warrant may not be so exercised.

          (d)  When any adjustment is required to be made in the Purchase Price,
the Company shall promptly mail to the Holder a certificate setting forth the
Purchase Price after such adjustment and setting forth in reasonable detail a
brief statement of the facts requiring such adjustment. Such certificate shall
also set forth the kind and amount of stock or other securities or property into
which this Warrant shall be exercisable following the occurrence of any of the
events specified in Section 2(a), (b) or (c) above.

     3.   Transfers.
          ---------

          (a)  Each Holder of this Warrant acknowledges that this Warrant and
the Warrant Stock have not been registered under the Securities Act, and agrees
not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose
of this Warrant or any Warrant Stock issued upon its exercise (other than to
Bank One or a majority owned subsidiary thereof which qualifies as an
"accredited investor" under Regulation D promulgated by the Securities and
Exchange Commission) in the absence of (i) an effective registration statement
under the Securities Act as to this Warrant or such Warrant Stock and
registration or qualification of this Warrant or such Warrant Stock under any
applicable Blue Sky or state securities law then in effect, or (ii) an opinion
of counsel, reasonably satisfactory to the Company, that such registration and
qualification are not required. Each certificate or other instrument for Warrant
Stock issued upon the exercise of this Warrant shall bear the following legend:

"THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED OTHER THAN TO
BANK ONE CORPORATION (OR A MAJORITY OWNED SUBSIDIARY THEREOF WHICH QUALIFIES AS
AN "ACCREDITED INVESTOR") WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH
ACT OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
THE CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED."

                                      -4-
<PAGE>

          (b)  Subject to the provisions of Section 3(a) hereof, this Warrant
and all rights hereunder are transferable, in whole or in part, upon surrender
of the Warrant with a properly executed assignment (in the form of Exhibit B
                                                                   ---------
hereto) at the principal office of the Company, and the transferee shall be
deemed to be a "Holder" hereunder, provided, however, that this Warrant may not
                ------             --------  -------
be transferred in whole or in part to any person or entity, other than Bank One
or a majority owned subsidiary of Bank One, the primary business of which is the
sale of automobiles, or the financing of the purchase or lease of automobiles,
over the Internet.

          (c)  Until any transfer of this Warrant is made in the warrant
register, the Company may treat the Holder of this Warrant as the absolute owner
hereof for all purposes; provided, however, that if and when this Warrant is
                         --------  -------
properly assigned in blank, the Company may (but shall not be required to) treat
the bearer hereof as the absolute owner hereof for all purposes, notwithstanding
any notice to the contrary and such transferee may be deemed by the Company to
be the "Holder."
        ------

          (d)  The Company will maintain a register containing the name and
address of the Holder of this Warrant. The Holder may change such Holder's
address as shown on the warrant register by written notice to the Company
requesting such change.

     4.   No Impairment. The Company will not, by amendment of its Articles of
          -------------
Incorporation or through reorganization, consolidation, merger, dissolution,
sale of assets or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will (subject
to Section 13 below) at all times in good faith assist in the carrying out of
all such terms and in the taking of all such action as may be reasonably
necessary or appropriate in order to protect the rights of the holder of this
Warrant against impairment.

     5.   Term of the Warrant.
          -------------------

          (a)  This Warrant shall be perpetual and survive any initial public
offering of the Company's Common Stock or any change of control of the Company.

     6.   Notices of Certain Transactions. In case:
          -------------------------------

          (a)  the Company shall take a record of the holders of its Common
Stock (or other stock or securities at the time deliverable upon the exercise of
this Warrant) for the purpose of entitling or enabling them to receive any
dividend or other distribution, or to receive any right to subscribe for or
purchase any shares of stock of any class or any other securities, or to receive
any other right to subscribe for or purchase any shares of stock of any class or
any other securities, or to receive any other right, or

          (b)  of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another corporation (other than a
consolidation or merger that is effected solely for changing the domicile of the
Company), any other transaction or series of related transactions pursuant to
which the Company's shareholders immediately prior thereto will possess a
minority of the voting power of the

                                      -5-
<PAGE>

surviving or acquiring entity immediately thereafter, or any transfer of all or
substantially all of the assets of the Company, or any other transaction which
would constitute a CarsDirect.com Event or give rise to an adjustment pursuant
to Section 2 hereof, or

          (c)  of the voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

the Company shall furnish the Holder or Holders hereof prompt written notice of
such event or action.

     7.   Representations and Warranties of Purchaser.
          -------------------------------------------

     Purchaser hereby represents and warrants that:

          (a)  Investment Representation. It is aware that the Common Stock to
be purchased hereunder has not been registered under the Securities Act of 1933,
as amended (the "Act"), or qualified under the California Corporate Securities
Law of 1968, as amended, or any other state securities or "blue sky" laws. Such
Common Stock is being acquired by it for investment purposes only and not for
sale or with a view to distribution of all or any part of such Common Stock.

          (b)  Access to Information. It has had an opportunity to ask questions
and receive answers from the Company regarding the terms and conditions of its
purchase of the Common Stock and regarding the business, financial affairs and
other aspects of the Company, and it has further had the opportunity to obtain
any information (to the extent the Company possesses or can acquire such
information without unreasonable effort or expense) which it deems necessary to
evaluate its investment or to verify the accuracy of information otherwise
provided to it.

          (c)  Investment Experience. It is experienced in evaluating and
investing in companies such as the Company, is capable of evaluating the merits
and risks of its investment in the Common Stock, is able to bear the economic
risk of the investment and is prepared to hold the Shares for an indefinite
period of time. It is an "accredited investor" within the meaning of Regulation
D under the Act.

          (d)  Restricted Securities. It understands that the shares of Common
Stock which may be purchased hereunder are characterized as "restricted
securities" under the federal securities laws inasmuch as they would be acquired
from the Company in a transaction not involving a public offering, and that
under such laws and applicable regulations such securities may be resold without
registration under the Act only in certain limited circumstances and that
otherwise such securities must be held indefinitely. In this connection,
Purchaser represents that it is familiar with SEC Rule 144, as presently in
effect, and the conditions which must be met in order for that Rule to be
available for resale of restricted securities, and understands the resale
limitations imposed by the Act.

     8.   Reservation of Stock. The Company will at all times reserve and keep
          --------------------
available, solely for the issuance and delivery upon the exercise of this
Warrant, such shares of Warrant Stock

                                      -6-
<PAGE>

and other stock, securities and property, as from time to time shall be issuable
upon the exercise of this Warrant. The Company covenants and agrees that all
shares of Warrant Stock which may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be duly authorized, validly
issued, fully paid (assuming payment of the exercise price by Holder) and
nonassessable and free from all preemptive rights of any shareholder and free of
all taxes, liens and charges with respect to the issue thereof. The Company will
take all such action as may be reasonably necessary to assure that such shares
of Warrant Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange upon which the Common Stock may be listed; provided, however, except as
                                                    --------  -------
may be provided in the Registration Rights Agreement, that the Company shall not
be required to effect a registration under Federal or state securities laws with
respect to such exercise.

     9.  Exchange of Warrants. Upon the surrender by the Holder of any Warrant
         --------------------
or Warrants, properly endorsed, to the Company at the principal office of the
Company, the Company will, subject to the provisions of Section 3 hereof, issue
and deliver to or upon the order of such Holder, at the Company's expense, a new
Warrant or Warrants of like tenor, in the name of such Holder or as such Holder
(upon payment by such Holder of any applicable transfer taxes) may direct,
providing for in the aggregate the number of shares of Warrant Stock provided
for in the Warrant or Warrants so surrendered.

     10. Replacement of Warrants. Upon receipt of evidence reasonably
         -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to the Company, or (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will issue, in lieu thereof, a new
Warrant of like tenor at the Holder's expense.

     11. Mailing of Notices. Any notice required or permitted pursuant to this
         ------------------
Warrant shall be in writing and shall be deemed delivered when delivered
personally or by fax (as evidenced by sender's confirmation receipt) or forty-
eight (48) hours after being deposited in the U.S. mail, as certified or
registered mail, with postage prepaid, addressed (a) if to the Holder, to Bank
One Corporation, c/o One First National Plaza, Suite 0897, Chicago, IL 60670,
Attn: William P. Boardman, Senior Executive Vice President, with a copy to
Daniel P. Cooney, Esq., One First National Plaza, Suite 0292, Chicago, IL 60670,
or as subsequently modified by written notice to the Company and (b) if to the
Company, to the address set forth below or as subsequently modified by written
notice to the Holder.

     12. No Rights as Stockholder. Until the exercise of this Warrant, the
         ------------------------
Holder of this Warrant shall not have or exercise any rights by virtue hereof as
a stockholder of the Company. Without limiting the generality of the foregoing,
and subject to Section 2 hereof, no dividends shall accrue to the shares of
Warrant Stock underlying this Warrant until the exercise hereof and the purchase
of the underlying shares of Warrant Stock, at which point dividends shall begin
to accrue with respect to such purchased shares of Warrant Stock from and after
the date such shares of Warrant Stock are so purchased.

                                      -7-
<PAGE>

     13. No Fractional Shares. No fractional shares of Warrant Stock will be
         --------------------
issued in connection with any exercise hereunder. In lieu of any fractional
shares which would otherwise be issuable, the Company shall pay cash equal to
the product of such fraction multiplied by the fair market value of one share of
Warrant Stock on the date of exercise, as determined in accordance with Section
1(c)(ii) hereof.

     14. Binding Effect on Successors. This Warrant shall be binding upon any
         ----------------------------
person succeeding to the Company by merger, consolidation or acquisition of all
or substantially all of the Company's assets only if and to the extent this
Warrant may be exercised after such event pursuant to Section 2(c).

     15. Amendment  or Waiver.  Any term of this  Warrant  may be amended or
         --------------------
waived only by an  instrument  in writing signed by the party against which
enforcement of the amendment or waiver is sought.

     16. Headings.  The headings in this Warrant are for purposes of reference
         --------
only and shall not limit or otherwise affect the meaning of any provision of
this Warrant.

     17. Governing Law. This Warrant shall be governed, construed and
         -------------
interpreted in accordance with the laws of the State of Delaware, without
giving effect to principles of conflicts of law.
