                                 PROMISSORY NOTE

US $5,122,625.00                                                  MARCH 31, 2004

      WHEREAS, Atari, Inc., a Delaware corporation (the "Holder"), previously
sold a development project to Atari Interactive, Inc., a Delaware corporation
(the "Obligor"), related to certain Dungeons & Dragons games (the "D&D
Project");

      WHEREAS, the D&D Project was transferred to Obligor effective as of
October 1, 2003 for a purchase price of Three Million Seven Hundred and
Forty-Four Thousand Dollars ($3,744,000) (the "Purchase Price");

      WHEREAS, as of the date hereof, the Obligor has not made payment of the
Purchase Price and the Holder has incurred an additional One Million Three
Hundred Seventy-Eight Thousand Six Hundred and Twenty-Five Dollars ($1,378,625)
in development expenses related to the transition of the D&D Project (the
"Additional Development Expenses"); and

      WHEREAS, the Obligor and its parent entity, Infogrames Entertainment, S.A.
("IESA"), agree that the Purchase Price and the Additional Development Expenses
are due and owing to the Holder and that payment of such amounts shall be made
in accordance with the terms of this Note.

      FOR VALUE RECEIVED, the Obligor hereby promises to pay to the order of the
Holder, the principal sum of Five Million One Hundred Twenty Two Thousand Six
Hundred Twenty Five Dollars ($5,122,625.00), with interest on the outstanding
principal amount at the rate per annum equal to the applicable Prime rate (as
quoted in the Wall Street Journal on the second to last business day of each
month) plus 1.25%, payable as set forth below.

      1.    Payments of Principal and Interest. Subject to the set off and
            acceleration provisions hereof, the principal due hereunder shall be
            payable in the following manner and on the following dates (each, a
            "Maturity Date"):

<PAGE>

            (a) $3,516,125 on the earlier to occur of (i) the date upon which
            Dungeons & Dragons Forgotten Realms: Demon Stone for Sony
            PlayStation2 is released for public sale or (ii) December 31, 2004;

            (b) $1,206,500 on the earlier to occur of (i) the date upon which
            Dungeons & Dragons Real Time Strategy for PC is released for public
            sale or (ii) December 31, 2004; and

            (c) $400,000 on December 31, 2004.

            Obligor shall pay interest to Holder in arrears on each respective
            Maturity Date with regard to any interest that has then accrued and
            is unpaid under this Note. Interest shall be calculated on the basis
            of a year of 360 days and for the number of days actually elapsed.
            In the event that any payment to be made hereunder shall be or
            become due on a Saturday, Sunday or any other day which is a legal
            bank holiday under the laws of the State of New York, such payment
            shall be or become due on the next succeeding business day. Any
            amounts of interest and principal not paid when due shall bear
            interest at the maximum rate of interest allowed by applicable law.
            All payments shall be applied first to accrued interest and
            thereafter to principal. The payments of principal and interest
            hereunder shall be made in coin or currency of the United States of
            America which at the time of payment shall be legal tender therein
            for the payment of public and private debts. All payments by Obligor
            under this Note shall be subject to the Holder's right of set-off
            and acceleration set forth herein and shall otherwise be free and
            clear without any deduction or withholding for any taxes or fees of
            any nature whatsoever, unless the obligation to make such deduction
            or withholding is imposed by law. The Obligor shall pay and save the
            Holder harmless from all liabilities with respect to or resulting
            from any delay or omission to make any such deduction or withholding
            required by law.

      2.    Prepayment. The Obligor shall have the right at any time to prepay
            the principal hereof in whole or in part, without premium or
            penalty, upon giving at least five (5) days prior written notice of
            such prepayment to the Holder, provided that interest on the
            principal hereof to be so prepaid, accrued to the date of such
            prepayment, shall be paid concurrently therewith.

      3.    Set-Off and Acceleration Rights of Holder. In the event that the
            Obligor fails to make any payment due hereunder on the applicable
            Maturity Date or earlier Event of Default, the Holder shall have the
            right to immediately set off the full amount of such delinquent
            payment(s) against any amounts then payable by the Holder to the
            Obligor, IESA, Paradigm Entertainment, Inc. or any subsidiary or
            affiliate entity of any of the above (collectively, the "Obligor
            Group Payables"), such set off to be allocated amongst the Obligor
            Group Payables in the Holder's sole discretion.

      4.    Covenants. (a) The Obligor covenants and agrees that, so long as
            this Note is outstanding and until payment in full of this Note, and
            the performance by the Obligor of all its other obligations arising
            hereunder, without the prior written consent of the Holder, the
            Obligor shall not create, incur, assume, or suffer to exist

                                     - 2 -

            any indebtedness, except (i) indebtedness incurred pursuant to this
            Note, (ii) indebtedness outstanding on the date hereof and set forth
            on Schedule A hereto; (iii) indebtedness to IESA; and (iv) trade
            credit in the ordinary course of business.

                  (b) The Obligor covenants and agrees that, so long as this
            Note is outstanding and until payment in full of this Note, and the
            performance by the Obligor of all its other obligations arising
            hereunder, without the prior written consent of the Holder, the
            Obligor shall not transfer, assign, sell, pledge or otherwise
            dispose of or encumber the 2,000,000 shares of Common Stock, $0.01
            par value, of the Holder issued in the name of the Obligor (the
            "Shares"). The Obligor further covenants and agrees that if all
            amounts hereunder are not paid in full on or before the applicable
            Maturity Date or earlier Event of Default, the Obligor shall within
            five (5) business days of the applicable Maturity Date or earlier
            Event of Default either (i) sell the Shares, in accordance with all
            applicable securities laws and Atari, Inc. policies, to any one or
            more third party purchasers and remit all proceeds from such sale(s)
            to the Holder, or (ii) transfer the Shares to the Holder at a per
            share price equal to the then current fair market value (as
            determined by the average closing price of the Common Stock of the
            Holder on the NASDAQ National Market (or such other market upon
            which the Common Stock of the Holder may then be trading) for the
            ten (10) trading days prior to the applicable Maturity Date or
            earlier Event of Default). Any monies or value received by the
            Holder as a result of the sale(s)/transfer contemplated by the
            preceding sentence shall be applied by the Holder against the
            Obligor Group Payables and shall be allocated amongst the Obligor
            Group Payables in the Holder's sole discretion.

      5.    No Waiver. No failure or delay by the Holder in exercising any
            right, power or privilege under this Note shall operate as a waiver
            thereof nor shall any single or partial exercise thereof preclude
            any other or further exercise thereof or the exercise of any other
            right, power or privilege. The rights and remedies herein provided
            shall be cumulative and not exclusive of any rights or remedies
            provided by law. No course of dealing between the Obligor and/or any
            other party acknowledging or agreeing to the terms hereof, and the
            Holder shall operate as a waiver of any rights by the Holder.

      6.    Waiver of Presentment and Notice of Dishonor. The Obligor and all
            endorsers, guarantors and other parties that may be liable under
            this Note hereby waive presentment, notice of dishonor, protest and
            all other demands and notices in connection with the delivery,
            acceptance, performance or enforcement of this Note.

      7.    Assignability/Replacement. The Holder may not assign or transfer
            this Note without the prior written consent of the Obligor other
            than to any affiliate of the Holder. The Obligor may not assign or
            delegate its rights or obligations hereunder without the prior
            written consent of Holder. The respective covenants and agreements
            of the Obligor, any other party acknowledging or agreeing to the
            terms hereof and the Holder under this Note shall be binding upon
            each of them and their respective successors and assigns. Upon
            receipt by the Obligor of evidence satisfactory to it of the loss,
            theft, destruction or mutilation of this Note, the Obligor

                                     - 3 -

            shall make and deliver a new Note of like tenor, in lieu of this
            Note, if (a) in case of loss, theft or destruction, the Obligor
            receives indemnity or security reasonably satisfactory to it, and
            (b) in the case of mutilation, this Note is surrendered and
            canceled.

                  judgment, or decree appointing, without the consent of the
                  Obligor, a receiver of the whole or any substantial part of

            be continuing, the Holder may, by written notice to the Obligor,
            declare the Note then outstanding to be due and payable in whole (or
            in part, in which case any principal not so declared to be due and
            payable may thereafter be declared to be due and payable), and
            thereupon the principal of the Note so declared to be due and
            payable, together with accrued interest thereon and all fees shall
            become due and payable immediately, without presentment, demand,
            protest or other notice of any kind, all of which are hereby waived
            by the Obligor. In case of any Event of Default described in clauses
            (b), (c), (d) and (e) of Section 9 above, the principal of the Note
            then outstanding, together with accrued interest thereon and all
            fees shall automatically become due and payable, without
            presentment, demand, protest or other notice of any kind, all of
            which are hereby waived by Obligor.

            (b) The Holder may proceed to protect and enforce its rights either
            by suit in equity and/or by action at law, whether for the specific
            performance of any covenant or agreement contained in this Note or
            in aid of the exercise of any power granted in this Note, or the
            Holder may proceed to enforce the payment of all sums due upon this
            Note or to enforce any other legal or equitable right of the Holder.
            The Obligor further promises to pay reasonable attorney's fees,
            court costs and other expenses, losses, charges, damages incurred or
            advances made by the Holder in the protection and enforcement of its
            rights or caused by the Obligor's default under the terms of this
            Note.

      11.   Amendments. Any term of this Note may be amended only with the
            written consent of the Obligor and the Holder. Any amendment
            effected in accordance with this Section 11 shall be binding upon
            the Holder of this Note, each future holder of this Note and the
            Obligor and any other party acknowledging or agreeing to the terms
            hereof.

      12.   Notices. Unless otherwise provided, any notice required or permitted
            under this Note shall be given in writing and shall be deemed
            effectively given upon personal delivery to the party to be

            advance written notice to the other party.

      13.   Severability. In the event that one or more of the provisions of
            this Note shall for any reason be held invalid, illegal or
            unenforceable in any respect, such invalidity, illegality or
            unenforceability shall not affect any other provision of this Note,
            but this Note shall be construed as if such invalid, illegal or
            unenforceable provision had never been contained herein.

      14.   Governing Law. This Note and the rights and obligations of the
            Obligor and the Holder and any other party acknowledging or agreeing
            to the terms hereof shall be governed by and construed in accordance
