"ASSET PURCHASE AGREEMENT"), which provides, among other things, for the
purchase by Humongous, Inc. ("HUMONGOUS") from Atari, of the Humongous IP and
other Purchased Assets (each as defined in the Asset Purchase Agreement) (the

of common stock of Humongous;

WHEREAS, when the Purchased Assets are transferred to Humongous in accordance
with the Asset Purchase Agreement, they will be subject to liens (the "LIENS")
in favor of HSBC Business Credit (USA) Inc. ("HSBC"), but HSBC has agreed that
at such time as Atari has received $7,000,000, in cash, from the sale of the New

Effective Date (defined below) and ending on December 31, 2005 (the "LIQUIDITY
PERIOD") in connection with arranging the sale of some or all of the New Shares,
as further described in this Agreement; and

                                                                        Page -1-

NOW, THEREFORE, in consideration of the mutual promises and premises hereof, and
for other good and valuable consideration, the receipt and sufficiency of which
the Parties do hereby acknowledge, the Parties hereby agree as follows:

      1.    Atari and IESA shall cooperate, during the Liquidity Period, for
            purposes of arranging the sale, without any commission to IESA, of
            some or all of the New Shares via one or more block trades or in
            another manner that constitutes an Offshore Transaction as that term
            is defined in Rule 902 under the U.S. Securities Act of 1933, as
            amended (the "SECURITIES ACT") with regard to transactions that are
            subject to Rule 903 under the Securities Act.

      2.    Given its knowledge of the French Paris market, IESA through its
            stock market brokers shall use commercially reasonable efforts to
            identify buyers willing to purchase from Atari some or all of the
            New Shares for a fair market price. All sales of the New Shares
            shall comply with Rules 902 and 903 under the Securities Act.

      3.    Upon settlement of any sell transactions for the New Shares, the
            proceeds of the sale net of brokers' fees (the "NEW SHARE PROCEEDS")
            shall be remitted in immediately available funds to an account of
            Atari (the "ATARI ACCOUNT.")

      4.    To the extent, if any, that the New Share Proceeds received by Atari
            as of September 6,2005 (the "DUE DATE"), do not reach Seven Million
            United States Dollars ($7,000,000,00)(such difference to be referred
            to herein as the "SHORTFALL AMOUNT"), IESA (i) shall cause a
            sufficient number of additional New Shares to be purchased from
            Atari, and/or (ii) shall transmit the sum equal to the Shortfall
            Amount to Atari on the Due date by wire transfer to the Atari
            Account of immediately available funds, so that the Shortfall Amount
            is paid to Atari no later than the close of business on the Due Date
            (such a purchase of additional New Shares and/or payment is referred
            to herein as a "SHORTFALL COVER PAYMENT").

      5.    In addition to the $7,000,000 mentioned above, the cumulative New
            Share Proceeds shall be applied by Atari to pay for the Post-Closing
            Costs. To the extent, if any, that at the time any Post-Closing
            Costs become due and payable, the New Share Proceeds plus any
            Shortfall Cover Payment and any Cost Cover Payments that Atari has
            received are in total less than (a) $7,000,000 plus (b) all the
            Post-Closing Costs Atari has previously incurred, plus (c) the
            Post-Closing Costs that are currently being incurred (such
            difference to be referred to herein as a "COST SHORTFALL AMOUNT"),
            IESA shall cause a sufficient number of additional New Shares to be
            purchased from Atari, and/or (ii) shall transmit the sum equal to
            the Cost Shortfall Amount to Atari, at or prior to the time the
            Post-Closing Costs become due and payable, so that the Cost
            Shortfall Amount is paid to Atari no later than the time the
            Post-Closing Costs become due and payable (each such a purchase of
            additional New Shares and/or payment is referred to herein as a
            "COST COVER PAYMENT"). The obligations of IESA under this Article 5
            will under no circumstances exceed $1,985,598.

      6.    In the event IESA makes a Shortfall Cover Payment or a Cost Cover
            Payment, IESA shall have the right, throughout the remainder of the
            Liquidity Period, to recoup the Shortfall Cover Payment and any Cost
            Cover Payments from any New Share Proceeds and, to that effect, any
            New Share Proceeds received thereafter shall be

                                                                        Page -2-

<PAGE>
      automatically wired by Atari to IESA up to the total amount of the
      Shortfall Cover Payment and all previously unrecouped Cost Cover Payments.
      To the extent the additional New Share Proceeds during the Liquidity
      Period do not enable IESA to recoup the Shortfall Cover Payment and all
      Cost Cover Payments, IESA will bear the deficiency.

7.    When Atari has received a total of $7,000,000 under paragraphs 3 and 4,
      Atari will immediately (a) notify HSBC that Atari has received $7,000,000,
      in cash, from the sale of the New Shares or otherwise in connection with
      the sale of Humongous to IESA, and therefore all the Liens on the
      Purchased Assets have terminated and (b) will request that HSBC deliver
      all documents that are reasonably necessary or appropriate to evidence the
      termination of those Liens.

8.    The Parties shall execute, acknowledge and deliver such other instruments
      or documents as may be reasonably necessary or appropriate to carry out
      the transactions contemplated by this Agreement. Specifically, at any
      time, from time to time following the Effective Date, at the request of
      IESA, Atari shall execute and deliver such instruments of sale, transfer,
      conveyance and assignment as required in order to facilitate and
      effectuate the sale of the New Shares and the delivery of the New Share
      Proceeds to Atari's bank account. Each Party will comply with the other
      Party's reasonable requests to assist the requesting Party in its efforts
      to effect the registration and sale of the New Shares as contemplated
      herein. Any and all fees and expenses associated with the sale of the New
      Shares shall be deducted from the New Shares Proceeds.

9.    This Agreement shall take effect upon the admission of the New Shares to
      listing on Euronext - Paris Bourse (the "Effective Date").

10.   This Agreement will not affect the rights or obligations of the parties
      under a letter dated August 9, 2005. from IESA to Atari relating, among
      other things, to IESA's purchase of Humongous.

IN WITNESS WHEREOF, the Parties have executed this Agreement as of the date
first above written.
