     FOR VALUE RECEIVED, Interplay Entertainment Corp., a Delaware corporation
(the "Company"), promises to issue in the name of, and sell and deliver to, Roth

Exercise Price being subject to adjustment in the circumstances set forth

                       SECTION 1.   Certain Definitions

                                    -------------------

     2.1  Exercise Period.  The Holder may exercise this Warrant, in whole or in
          ---------------
part(but not as to a fractional share), at any time and from time to time,
during the Exercise Period.

     2.2  Exercise Procedure.
          ------------------

          (a)  This Warrant will be deemed to have been exercised at such time
as the Company has received all of the following items (the "Exercise Date"):

               (i)    a completed Exercise Agreement, in the form set forth as
Exhibit I hereto, executed by the Person exercising all or part of the purchase
rights represented by this Warrant (the "Purchaser");

               (ii)   this Warrant (subject to delivery by the Company of a new
Warrant with respect to any unexercised portion, as provided in Subsection
2.2(b));

                                       2
<PAGE>

               (iii)  if this Warrant is not registered in the name of the
Purchaser, an Assignment or Assignments in the form set forth as Exhibit II
hereto, evidencing the assignment of this Warrant to the Purchaser; and

               (iv)   a cashier's or official bank check or other immediately
available funds payable to the Company in an amount equal to the sum of the
product of the Exercise Price multiplied by the number of Warrant Shares being
purchased upon such exercise. Notwithstanding anything contained herein to the
contrary, the Exercise Price for the Warrant may be satisfied by the delivery of
an unexercised portion of this Warrant to the Company or the Transfer Agent for
cancellation having a value, as determined by the spread as of the date of
surrender equal to the difference between the then applicable Exercise Price and
the Market Price of the shares of Common Stock underlying this Warrant, equal to
the aggregate Exercise Price of the portion of this Warrant desired to be then
exercised.

          (b)  Certificates for Warrant Shares purchased upon exercise of this
Warrant will be delivered by the Company to the Purchaser within five calendar
days after the Exercise Date. Unless this Warrant has expired or all of the
purchase rights represented hereby have been exercised, the Company will prepare
a new Warrant representing the rights formerly represented by this Warrant that
have not expired or been exercised. The Company will, within such five-day
period, deliver such new Warrant to the Person designated for delivery in the
Exercise Agreement.

          (c)  The Warrant Shares issuable upon the exercise of this Warrant
will be deemed to have been transferred to the Purchaser on the Exercise Date,
and the Purchaser will be deemed for all purposes to have become the record
holder of such Common Stock on the Exercise Date.

          (d)  The issuance of certificates for Warrant Shares upon exercise of
this Warrant will be made without charge to the Holder or the Purchaser for any
issuance tax in respect thereof or any other cost incurred by the Company in
connection with such exercise and the related transfer; provided, however, that
the Company shall not be required to pay any tax that may be payable in respect
of any transfer involved in the issuance and delivery of any certificate or
instrument in a name other than that of the Holder of this Warrant, and the
Company shall not be required to issue or deliver any such certificate or
instrument unless and until the Person or Persons requesting the issue thereof
shall have paid to the Company the amount of such tax or shall have established
to the satisfaction of the Company that such tax has been paid.

          (e)  The Company will not close its books for the transfer of this
Warrant or of any of the Warrant Shares in any manner that interferes with the
timely exercise of this Warrant. The Company will from time to time take all
such action as may be necessary to assure that the par value per share of the
unissued Common Stock acquirable upon exercise of this Warrant is at all times
equal to or less than the Warrant Share Exercise Price then in effect.

     2.3  Exercise Agreement.  The Exercise Agreement will be substantially
          ------------------
in the form set forth as Exhibit I hereto, except that if the Warrant Shares are
not to be issued in the name of the Holder of this Warrant, the Exercise
Agreement will also state the name of the Person to

                                       3
<PAGE>

whom the certificates or instrument for the Warrant Shares are to be issued, and
if the number of Warrant Shares purchasable does not include all of such
securities purchasable hereunder, it will also state the name of the Person to
whom a new Warrant for the unexercised portion of the rights hereunder is to be
delivered.

     2.4   Fractional Shares.  If a fractional share of Common Stock would, but
           -----------------
for the provisions of Subsection 2.1, be issuable upon exercise of the rights
represented by this Warrant, the Company will, within 20 days after the Exercise
Date, deliver to the Purchaser a check payable to the Purchaser, in lieu of such
fractional share, in an amount equal to the Market Price of such fractional
share as of the close of business on the Exercise Date.

                           Section 3. Exercise Price
                                      --------------

     3.1   General. The Holder of this Warrant shall be entitled to purchase
           -------
such numbers of Warrant Shares at the Exercise Price as are specified on the
cover page.

     3.2   Subdivision or Combination of Common Stock and Stock Dividends.  If
           --------------------------------------------------------------
the Company shall at any time after the date hereof (a) issue any shares of
Common Stock or Convertible Securities, or any rights to purchase Common Stock
or Convertible Securities, as a dividend upon Common Stock, (b) issue any shares
of Common S tock, in subdivision of outstanding shares of Common Stock by
reclassification or otherwise, or (c) combine outstanding shares of Common
Stock, by reclassification or otherwise, then the Exercise Price that would
apply if purchase rights hereunder were being exercised immediately prior to
such action by the Company shall be adjusted by multiplying it by a fraction,
the numerator of which shall be the number of shares of Common Stock Deemed
Outstanding  immediately prior to such dividend, subdivision, or combination and
the denominator of which shall be the number of shares of Common Stock Deemed
Outstanding immediately after such dividend, subdivision, or combination.

     3.3   Certain Dividends or Distributions.  If the Company shall declare a
           ----------------------------------
dividend or distribution upon the Common Stock payable otherwise than out of
earnings or earned surplus and otherwise than in Common Stock, Rights or
Convertible Securities, the Exercise Price that would apply if purchase rights
hereunder were being exercised immediately prior to the declaration of such
dividend or  distribution shall be reduced by an amount equal, in the case of a
dividend or distribution in cash, to the amount thereof payable per share of the
Common Stock or, in the case of any other dividend or distribution, to the fair
value of such dividend or distribution per share of the Common Stock as
determined in good faith by the Board of Directors of the Company.  For purposes
of the foregoing, a dividend or distribution other than in cash shall be
considered payable out of earnings or earned surplus only to the extent that
such earnings or earned surplus are charged an amount equal to the fair value of
such dividend or distribution as determined in good faith by the Board of
Directors of the Company.  Such reductions shall take effect as of the date on
which a record is taken for the purpose of such dividend or distribution or, if
a record is not taken, the date as of which the holders of Common Stock of
record entitled to such dividend or distribution are to be determined.

     3.4   No De Minimis Adjustments.  No adjustment of the Exercise Price
           -------------------------
shall be made if the amount of such adjustment would be less than one cent per
share, but in such case any adjustment that otherwise would be required to be
made shall be carried forward and shall be

                                       4
<PAGE>

made at the time and together with the next subsequent adjustment that, together
with any adjustment or adjustments so carried forward, shall amount to not less
than one cent per share.

       Section 4. Adjustment of Number of Shares Issuable upon Exercise
                  -----------------------------------------------------

     Upon each adjustment of the Exercise Price pursuant to Section 3, the
Holder of this Warrant shall thereafter (until another such adjustment) be
entitled to purchase, (i) at the adjusted Exercise Price in effect on the date
purchase rights for Warrant Shares under this Warrant are exercised, the number
of Warrant Shares, calculated to the nearest whole number, determined by (a)
multiplying the number of Warrant Shares purchasable hereunder immediately prior
to the adjustment of the Exercise Price by the Exercise Price in effect
immediately prior to such adjustment, and (b) dividing the product so obtained
by the adjusted Exercise Price in effect on the date of such exercise.  The
provisions of Subsection 2.4 shall apply, however, so that no fractional Warrant
Share shall be issued upon exercise of this Warrant.

Section 5. Effect of Reorganization, Reclassification, Consolidation, Merger, or
           ---------------------------------------------------------------------
           Sale
           ----

     If at any time while this Warrant is outstanding there shall be any
reorganization or reclassification of the capital stock of the Company (other
than a subdivision or combination of shares provided for in Subsection 3.3
hereof), any consolidation or merger of the Company with another corporation
(other than a consolidation or merger in which the Company is the surviving
entity and which does not result in any change in the Common Stock), or any sale
or other disposition by the Company of all or substantially all of its assets to
any other corporation, then the Holder of this Warrant shall thereafter upon
exercise of this Warrant be entitled to receive the number of Warrant Shares or
other securities or property of the Company, or of the successor corporation
resulting from such consolidation or merger, as the case may be, to which the
Holders of the Warrant Shares (and any other securities and property) of the
Company, deliverable upon the exercise of this Warrant, would have been entitled
upon such reorganization, reclassification of capital stock, consolidation,
merger, sale, or other disposition if this Warrant had been exercised
immediately prior to such reorganization, reclassification of capital stock,
consolidation, merger, sale, or other disposition.  In any such case,
appropriate adjustment (as determined in good faith by the Board of Directors of
the Company) shall be made in the application of the provisions set forth in
this Warrant with respect to the rights and interests thereafter of the Holder
of this Warrant to the end that the provisions set forth in this Warrant
(including those relating to adjustments of the Exercise Price and the number of
Warrant Shares issuable upon the exercise of this Warrant) shall thereafter be
applicable, as near as reasonably may be, in relation to any shares or other
property thereafter deliverable upon the exercise hereof as if this Warrant had
been exercised immediately prior to such reorganization, reclassification of
capital stock, consolidation, merger, sale, or other disposition and the Holder
hereof had carried out the terms of the exchange as provided for by such
reorganization, reclassification of capital stock, consolidation, or merger.
The Company shall not effect any such reorganization, consolidation, or merger
unless, upon or prior to the consummation thereof, the successor corporation
shall assume by written instrument the obligation to deliver to the Holder
hereof such shares of stock or other securities, cash, or property as such
Holder shall be entitled to purchase in accordance with the foregoing
provisions. Notwithstanding any other provisions of this Warrant, in the event
of sale or other disposition of all or substantially all of the assets of the
Company as a part of a plan for liquidation of the Company, all rights to
exercise the

                                       5
<PAGE>

Warrant shall terminate upon the earlier of the expiration of the Exercise
Period and 60 days after the Company gives written notice to the Holder of this
Warrant that such sale or other disposition has been consummated.

             Section 6. Additional Adjustment of Number of Shares
                        ------------------------------------------

     The number of shares of common stock purchasable hereunder shall
automatically be increased to 500,000 shares (as such number may be adjusted
pursuant to Sections 3, 4 and 5 of this Warrant) if, and only if, the Company
has entered into an amendment of Investor Warrants (as defined below) covering
85% of the aggregate number of shares covered by all Investor Warrants, which
amendment shall provide that any right to exercise such Investor Warrants for
additional shares pursuant to Section 5(e) of the Investor Warrants shall
terminate upon a sale of the Company at a price of more than $2.75 per share.
The warrant price and other terms of this warrant shall be unaffected by any
such increase.  "Investor Warrants" means the Warrants issued to investors
pursuant to the Subscription Agreement dated March 29, 2001 between the Company
and such investors (the "Investor Warrants").

                        Section 7. Notice of Adjustment
                                   --------------------

     Immediately upon any adjustment of the Exercise Price or increase or
decrease in the number of Warrant Shares, the Company will send written notice
thereof to all Holders, stating the adjusted Exercise Price, and the increased
or decreased number of Warrant Shares and setting forth in reasonable detail the
method of calculation for such adjustment and increase or decrease.  When
appropriate, such notice may be given in advance and included as part of any
notice required to be given pursuant to Section 8 below.  Notwithstanding
anything herein to the contrary, if any adjustment under this Warrant of the
Exercise Price or the number of shares of Common Stock issuable upon exercise of
this Warrant, shall be determined by NASD Regulation, Inc. (the "NASD") to
violate the Rules of Fair Practice of the NASD, and such determination shall not
be subject to further appeal or review, the violative provisions shall be deemed
to be amended to the minimum extent necessary to cause each such provision to
comply with the applicable violated section of the NASD Rules of Fair Practice.

                  SECTION 8. Prior Notice of Certain Events
                             ------------------------------
     If at any time:

          (a)  the Company shall pay any dividend payable in stock upon its
Common Stock or make any distribution (other than cash dividends) to the holders
of its Common Stock;

          (b)  the Company shall offer for subscription pro rata to the holders
                                                        --- ----
of its Common Stock any additional shares of stock of any class or any other
rights;

          (c)  there shall be any reorganization or reclassification of the
capital stock of the Company, any consolidation or merger of the Company with
another corporation, or a sale or disposition of all or substantially all its
assets; or

          (d)  there shall be a voluntary or involuntary dissolution,
liquidation, or winding up of the Company,

                                       6
<PAGE>

then, in each such case, the Company shall give prior written notice, by hand
delivery, by overnight delivery or by certified mail, postage prepaid, addressed
to the Holder of this Warrant at the address of such holder as shown on the
books of the Company, of the date on which (i) the books of the Company shall
close or a record shall be taken for such stock dividend, distribution, or
subscription rights or (ii) such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation, or winding up shall take
place, as the case may be.  A copy of each such notice shall be sent
simultaneously to each transfer agent of the Company's Common Stock. Such notice
shall also specify the date as of which the holders of Common Stock of record
shall participate in said dividend, distribution, or subscription rights or
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation, or winding up, as the case may be.  Such
written notice shall be given at least 30 days prior to the record date or the
effective date, whichever is earlier, of the subject action or other event.

     If any other event (not listed above) would require adjustment to the
Exercise Price, then the Company shall give prior written notice thereof (in
substance as set forth above) to the Holders, at their addresses and in the
manner provided in Subsection 14.3.  Notwithstanding the foregoing, the Company
shall not be required to give prior written notice where it is not reasonably
possible.

                 Section 9.  Reservation of Common Stock
                             ---------------------------

     The Company will at all times reserve and keep available such number of
shares of Common Stock as will be sufficient to permit the exercise in full of
all outstanding Warrants.  Upon exercise of this Warrant, the Holder will
acquire fully paid and non-assessable ownership rights of the Common Stock, free
and clear of any liens, claims or encumbrances.  As long as the Warrants shall
be outstanding, the Company shall use its best efforts to cause all shares of
Common Stock issuable upon the exercise of the Warrants to be listed (subject to
official notice of issuance) on all securities exchanges on which the Common
Stock issued to the public in connection herewith may then be listed and/or
quoted on NNM or Nasdaq SmallCap Market.

              Section 10.  No Shareholder Rights or Obligation
                           -----------------------------------

     This Warrant will not entitle the holder hereof to any voting rights or
other rights as a shareholder of the Company.  Until the shares of Common Stock
issuable upon exercise of this Warrant are recorded as issued on the books and
records of the Company's transfer agent, the Holder shall not be entitled to any
voting rights or other rights as a shareholder; provided, however, the Company
uses its best efforts to ensure that, upon receipt of an Exercise Agreement, the
appropriate documentation necessary to effectuate the exercise of the Warrant
and issuance of the Common Stock is accomplished as expeditiously as possible.
No provision of this Warrant, in the absence of affirmative action by the Holder
to purchase Common Stock, and no enumeration in this Warrant of the rights or
privileges of the Holder, will give rise to any obligation of such Holder for
the Exercise Price of the Warrant Shares acquirable by exercise hereof or as a
shareholder of the Company.

                                       7
<PAGE>

           Section 11.  Exchangeable for Different Denominations
                        ----------------------------------------

     This Warrant is exchangeable, upon the surrender hereof by the Holder at
the principal office of the Company, for new Warrants of like tenor representing
in the aggregate the purchase rights hereunder, and each of such new Warrants,
as set forth on the front page hereof, will represent such portion of such
rights as is designated by the Holder at the time of such surrender.  The date
the Company initially issued this Warrant, which is set forth on the front page
hereof, will be deemed to be the "Date of Issuance" of this Warrant and any
purchase warrant exchanged or substituted herefor, regardless of the number of
times (and dates on which) new certificates representing the unexpired and
unexercised rights formerly represented by this Warrant are issued.

                       Section 12.  Transferability
                                    ---------------

     Subject to the transfer conditions referred to in Section 2 or in the
remaining provisions or this Section 12, this Warrant and all rights hereunder
are transferable, in whole or in part, without charge to the Holder, upon
surrender of this Warrant with a properly executed Assignment (in the form of
Exhibit II hereto) at the principal office of the Company.  This Warrant and the
Warrant Shares may not be offered, sold, or transferred except in compliance
with the Securities Act of 1933, as amended (the "Act"), and any applicable
state securities laws; and then only against receipt of an agreement of the
Person to whom such offer or sale is made to comply with the provisions of this
Section 12 with respect to any resale or other disposition of such securities;
provided that no such agreement shall be required from any Person purchasing
this Warrant or any Warrant Shares pursuant to a registration statement
effective under the Act.  The Holder of this Warrant agrees that, prior to the
disposition of any security purchased on the exercise hereof under circumstances
that might require registration of such security under the Act, or any similar
statute then in effect, the Holder shall give written notice to the Company,
expressing his intention as to such disposition.  Promptly upon receiving such
notice, the Company shall present a copy thereof to its securities counsel.  If,
in the opinion of such counsel, the proposed disposition does not require
registration of such security under the Act, or any similar statute then in
effect, the Company shall, as promptly as practicable, notify the Holder of such
opinion, whereupon the Holder shall be entitled to dispose of such security in
accordance with the terms of the notice delivered by the Holder to the Company.
The above agreement by the Holder of this Warrant shall not be deemed to limit
or restrict in any respect the exercise of rights set forth in Section 13
hereof.

                       Section 13.   Registration Rights
                                     -------------------

     13.1  Registration Rights.  The Company will use its best efforts file a
Registration Statement with the SEC for the resale of the Warrant Shares (as
defined below) within 14 days after the Date of Issuance, and the Company will
further use its best efforts to assure that such Registration Statement is
effective within 60 days after the Date of Issuance.   For the purposes of this
Warrant:  (A) "Registrable Shares" means the Warrant Shares (and including any
shares issued in connection with any split or dividend in respect of any such
shares); provided, however, that any such Share will cease to be a Registrable
Share when (1) a Registration Statement covering a Registrable Share has been
declared effective by the SEC and such Share has been disposed of by the
Holder(s) pursuant to such effective Registration Statement, (2) such share
(after initial issuance) is held by the Company or otherwise ceases to be
outstanding, or (3)

                                       8
<PAGE>

such share may be traded without restriction pursuant to paragraph (k) of Rule
144, if applicable; and (B) "Registration Statement" means any registration
statement or comparable document under the Act through which a public sale or
disposition of the Registrable Shares may be registered, including the
prospectus, amendments and supplements to such registration statement, all
exhibits, and all material incorporated by reference or deemed to be
incorporated by reference in such registration statement.

     13.2  Suspension Of Effectiveness.  The Company's obligations under Section
13.1 above shall not restrict its ability to suspend the effectiveness of, or
direct the Holder(s) not to offer or sell securities under, any Registration
Statement, at any time, for such reasonable period of time which the Company
believes is necessary to prevent the premature disclosure of any events or
information having a material effect on the Company.  In addition, the Company
shall not be required to keep any Registration Statement effective, or may,
without suspending such effectiveness, instruct the Holder(s) not to sell such
securities, during any period during which the Company is instructed, directed,
ordered or otherwise requested by any governmental agency or self-regulatory
organization to stop or suspend such trading or sales.

     13.3  Registration Procedures.  Except as otherwise expressly provided
herein, in connection with any registration of Registrable Shares pursuant to
this Warrant, the Company shall:

(a) in accordance with the terms of Section 13.1, prepare and file with the SEC
a Registration Statement with respect to such Registrable Shares and use its
best efforts to cause such Registration Statement to become effective as soon as
practicable, and thereafter keep such Registration Statement effective for one
(1) year subsequent to the Expiration Date or, if earlier, until the
distribution contemplated in the Registration Statement has been completed; and
before filing a Registration Statement or prospectus or any amendments or
supplements thereto, furnish to the Holder(s) copies of such Registration
Statement and such other documents as proposed to be filed (including copies of
any document to be incorporated by reference therein), and thereafter furnish to
the Holder(s) such number of copies as may be reasonably requested in writing by
the Holder(s) of such Registration Statement, each amendment and supplement
thereto (including copies of any document to be incorporated by reference
therein), including all exhibits thereto, the prospectus included in such
Registration Statement (including each preliminary prospectus), and, promptly
after the effectiveness of a Registration Statement, the definitive final
prospectus filed with the SEC;

(b) notify the Holder(s), at any time when a prospectus relating thereto is
required to be delivered under the Act, of the occurrence of any event as a
result of which the prospectus included in such Registration Statement
(including any document to be incorporated by reference therein) contains an
untrue statement of a material fact or omits any fact necessary to make the
statements therein not misleading and, at the request of the Holder(s), the
Company shall prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Shares, such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading and promptly make available to the Holder(s)
any such supplement or amendment;

                                       9
<PAGE>

(C) notify the Holder(s) and the managing underwriters, if any, promptly, and
(if requested by any such Person) confirm such advice in writing, (i) when the
Registration Statement, the prospectus or any prospectus supplement or post-
effective amendment has been filed, and, with respect to the Registration
Statement or any post-effective amendment, when the same has become effective,
(ii) of the issuance by the SEC of any stop order suspending the effectiveness
of a Registration Statement or of any order preventing or suspending the use of
any preliminary prospectus or the initiation of any proceedings for that purpose
and the Company shall promptly use its reasonable best efforts to prevent the
issuance of any stop order or to obtain its withdrawal if such stop order should
be issued and (iii) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from qualification
of a Registration Statement or any of the Registrable Shares for offer or sale
in any jurisdiction, or the initiation or threatening of any proceeding for such
purpose.

     The Company may require the Holder(s) to furnish to the Company such
information regarding themselves and the distribution of such Registrable Shares
as the Company may from time to time reasonably request in writing and such
other information as may be legally required in connection with such
registration.  The Holder(s) agree, by their acquisition of Registrable Shares
and their acceptance of the benefits provided to it hereunder, to furnish
promptly to the Company all information required to be disclosed in order to
make any previously furnished information not materially misleading.  All
Holder(s) proposing to distribute their Registrable Shares through such
underwriting shall (together with the Company) enter into an underwriting
agreement in customary form with the underwriter or underwriters selected by the
Company for such underwriting and shall provide to such underwriter or
underwriters any opinions and certificates, and any indemnification with respect
to such Holder as reasonably required by such underwriter or underwriters.

     The Holder(s) agree that upon receipt of any notice from the Company of the
happening of any event of the kind described herein requiring the cessation of
the distribution of a prospectus or the distribution of a supplemented or
amended prospectus, the Holder(s) will forthwith discontinue disposition of
Registrable Shares pursuant to the Registration Statement covering such
Registrable Shares until the Holder(s)' receipt of the copies of the
supplemented or amended prospectus contemplated by this Warrant, or until it is
advised in writing by the Company that the use of the prospectus may be resumed,
and, if so directed by the Company, the Holder(s) will deliver to the Company
(at the Company's expense) all copies, other than permanent file copies then in
the Holder(s)' possession, of the prospectus covering such Registrable Shares
current at the time of receipt of such notice.

     Nothing contained in this Agreement shall be construed as requiring the
Holder(s) to exercise their Warrants prior to the filing of the Registration
Statement or the effectiveness thereof.

     The Company shall furnish to each Holder participating in the offering and
to each underwriter, if any, a signed counterpart, addressed to such Holder or
underwriter, of (i) an opinion of counsel to the Company, dated the effective
date of such registration statement (and, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under the
underwriting agreement), and (ii) a "cold comfort" letter dated the effective
date of such registration statement (and, if such registration includes an
underwritten public

                                       10
<PAGE>

offering, a letter dated the date of the closing under the underwriting
agreement) signed by the independent public accountants who have issued a report
on the Company's financial statements included in such registration statement,
in each case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

     The Company shall deliver promptly to each Holder participating in the
offering requesting the correspondence and memoranda described below and to the
managing underwriter, if any, copies of all correspondence between the
Commission and the Company, its counsel or auditors and all memoranda relating
to discussions with the Commission or its staff with respect to the registration
statement and permit each Holder and underwriter to do such investigation, upon
reasonable advance notice, with respect to information contained in or omitted
from the registration statement as it deems reasonably necessary to comply with
applicable securities law or rules of the NASD.  Such investigation shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times and as often as such Holder or
underwriter shall reasonably request.

     12.4   Registration Expenses.  All expenses incident to the Company's
performance of or compliance with the registration of shares pursuant to this
Warrant, including, without limitation, all registration and filing fees, fees
and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel of the Company and counsel for the
underwriters in connection with "blue sky" qualifications of the Registrable
Shares), fees and expenses associated with filings required to be made with the
National Association of Securities Dealers, Inc., and with listing on any
national securities exchange or exchanges in which listing may be sought,
printing expenses, messenger and delivery expenses, fees and expenses of any
counsel, accountants, or other persons retained or employed by the Holder(s) or
underwriters, fees and expenses of counsel for the Company and its independent
certified public accountants, securities acts liability insurance (if the
Company elects to obtain such insurance), the fees and expenses of any special
experts retained by the Company in connection with such registration, and fees
and expenses of other persons retained by the Company (all such expenses being
herein called "Registration Expenses") will be borne by the Company; provided
that in no event shall Registration Expenses payable by the Company include any
(i) underwriting discounts, commissions, or fees attributable to the sale of
Registrable Shares, or (ii) transfer taxes, if any.

     12.5 Indemnification.

        (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, the partners or officers, directors and stockholders of
each Holder, legal counsel and accountants for each Holder, any underwriter (as
defined in the Act) for such Holder and each person, if any, who controls such
Holder or underwriter within the meaning of the Act or the Exchange Act, against
any losses, claims, damages or liabilities (joint or several) to which they may
become subject under the Act, the Exchange Act or any state securities laws,
insofar as

                                       11
<PAGE>

such losses, claims, damages, or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the Exchange Act, any state securities laws
or any rule or regulation promulgated under the Act, the Exchange Act or any
state securities laws; and the Company will reimburse each such Holder,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this subsection 13.5(a) shall not apply to amounts paid
in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation that occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person;
provided further, however, that the foregoing indemnity agreement with respect
to any preliminary prospectus shall not inure to the benefit of any Holder or
underwriter, or any person controlling such Holder or underwriter, from whom the
person asserting any such losses, claims, damages or liabilities purchased
shares in the offering, if a copy of the prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) was not sent or given by or on behalf of such Holder or underwriter to
such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the shares to such person, and if the
prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim, damage or liability.

        (b) To the extent permitted by law, each Holder, severally and not
jointly, will indemnify and hold harmless the Company, each of its directors,
each of its officers who has signed the Registration Statement, each person, if
any, who controls the Company within the meaning of the Act, legal counsel and
accountants for the Company, any underwriter, each other Holder selling Shares
in the Registration Statement and any controlling person of any such underwriter
or other Holder, against any losses, claims, damages or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Act, the Exchange Act or any state securities laws, insofar as such losses,
claims, damages or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with the Registration Statement; and each such Holder will reimburse any person
intended to be indemnified pursuant to this subsection 13.5(b), for any legal or
other expenses reasonably incurred by such person in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this subsection
13.5(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder (which consent shall not be unreasonably withheld), provided that
in no event shall any indemnity under this subsection 13.5(b) exceed the gross
proceeds from the offering received by such Holder.

                                       12
<PAGE>

        (c) Promptly after receipt by an indemnified party under this Section
13.5 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 13.5, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties that may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
13.5, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 13.5.

        (d) If the indemnification provided for in this Section 13.5 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage or expense referred to herein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage or expense, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

        (e) The obligations of the Company and Holder(s) under this Section 13.5
shall survive the completion of any offering of Registrable Securities in a
Registration Statement under this Section 1, and otherwise.

                          SECTION 14.  Miscellaneous

                         VULCAN VENTURES INCORPORATED

     This Agreement is made as of this 10th day of September 2001, by and
between InfoSpace, Inc., a Delaware corporation (the "Company") and Vulcan
Ventures Incorporated ("Seller").

     WHEREAS, Seller is the holder of 21,698,778 shares of the Company's Common
Stock; and

     WHEREAS, the Company has agreed to purchase 21,698,778 shares of its Common
Stock held by Seller at a price of $1.05 per share with the purchase price of
such shares to be paid by check or wire transfer of immediately available funds
to an account specified by Seller ("Seller's Account");

     NOW THEREFORE, in consideration of the mutual covenants and representations
herein set forth, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and Seller agree as
follows:

     1.   Purchase and Sale of Stock. Subject to the terms and conditions of
          --------------------------
this Agreement, Seller hereby agrees to sell to the Company and the Company
agrees to purchase from Seller on the Closing Date (as herein defined),
21,698,778 shares of the Company's Common Stock (the "Shares") at a price of
$1.05 per share, for an aggregate purchase price of $22,783,716.90. The purchase
price for the Shares shall be paid by the Company on the Closing Date by check
or wire transfer of immediately available funds to Seller's Account.

     2.   Closing. The purchase and sale of the Shares shall occur
          -------
simultaneously with the execution and delivery of this Agreement (the "Closing
Date"). The Closing will take place at the principal office of the Company. At
the Closing, Seller shall deliver to the Company one or more stock certificates
representing the Shares (other than the Shares held in street name, which will
be transferred by appropriate written instructions), together with a duly
executed stock power authorizing transfer of the Shares to the Company in form
and substance reasonably satisfactory to the Company against payment to Seller
of the purchase price therefor by check delivered at the Closing or wire
transfer pursuant to Section 1.

     3.   Company's Representations. In connection with its purchase of the
          -------------------------
Shares hereunder, the Company hereby represents and warrants to Seller as
follows:

             (a) Corporate Power. The Company has all requisite corporate power
                 ---------------
and authority to execute and deliver this Agreement and to perform its
obligations under this Agreement.
<PAGE>

                 ---------

performance by the Company of this Agreement and the consummation of the
transactions contemplated hereunder has been taken, including the approval of
this Agreement and the transactions contemplated hereby by the members of the
Company's Board of Directors that are not affiliated with Seller. This Agreement
constitutes the legal, valid and binding obligation of the Company, enforceable
against the Company in accordance with its terms.

participation as a director and committee member of the Company, (ii) review of
reports, documents, studies and other information communicated to Savoy in
connection with his participation as a director and committee member of the
Company and (iii) review of reports regularly filed by the Company with the

satisfaction from, representatives of the Company concerning the Company and the
terms and conditions of the transactions contemplated by this Agreement.

     5.   Release by Seller. In consideration for the Company's purchase of the

subsidiaries, successors and assigns, hereby irrevocably and unconditionally
releases, acquits and forever discharges Company and its past and present
agents, officers, directors, employees, affiliates, divisions, subsidiaries,
predecessor and successor corporations, assigns, attorneys and representatives
(each, a "Released Party") from any and all charges, complaints, claims,
liabilities, obligations, promises, agreements, controversies, damages, actions,
causes of action, suits, rights, demands, costs, losses, debts, judgments and
expenses of any nature whatsoever (any of the foregoing, a "Claim"), known or
unknown, suspected or unsuspected, fixed or contingent which Seller now has,
owns, holds, or claims to have, claims to own, or claims to hold, or which
Seller at any time heretofore had, owned, held or claimed to have, claimed to
own, or claimed to have held, or which Seller at any time hereafter may have,
own, hold or claim to have, claim to own, or claim to hold, against the Company
solely to the extent such Claims directly or indirectly arise out of or relate
to Seller's purchase and ownership of the Shares and any other securities of the
Company previously owned by Seller, the sale of the Shares pursuant to this
Agreement and any prior sales of securities of the Company, including but not
limited to any Claim asserted or assertable by Seller pursuant to Section 10(b)
and Rule 10b-5 of the Exchange Act. For the purposes of implementing a full and
complete release and discharge of the Company and the other Released Parties,

the aforesaid which Seller does not know or suspect to exist in its favor at the
time it signs this Agreement, and that this Agreement is intended to fully and
finally resolve any such Claim or Claims. Nothing contained herein shall
adversely affect any of Savoy's rights to indemnification by contract, law, the
Certificate of Incorporation or Bylaws of the Company or under any insurance
coverage.
