                            EUROPLAY PROMISSORY NOTE

$4,327,500                                                        APRIL 30, 2002


            FOR VALUE RECEIVED, and pursuant to that certain Stock Purchase
Agreement dated April 23, 2002 by and among INFOGRAMES, INC., a Delaware
corporation ("BUYER"), Shiny Entertainment, Inc., Interplay Entertainment Corp.
("INTERPLAY"), Shiny Group, Inc. and David Perry, Buyer unconditionally promises
pursuant to this Promissory Note ("NOTE") to pay to EUROPLAY 1 LLC ("EUROPLAY")
in the manner, and on the dates and place hereinafter provided, the principal
sum of Four Million Three Hundred Twenty-Seven Thousand Five Hundred Dollars
($4,327,500), together with accrued interest from the date hereof.

            Section 1. INTEREST. Buyer also promises to pay interest on the
unpaid principal amount hereof from the date hereof until paid in full at a rate
of 2.88% per annum, the short-term federal rate applicable for the month of
April, 2002. Computation of interest will be made on the basis of a 365-day
year, for the actual number of days elapsed in the relevant period (including
the first day but excluding the last day).

            Notwithstanding anything to the contrary set forth in the preceding
paragraph, if a court of competent jurisdiction determines in a final order that
the rate of interest payable hereunder exceeds the highest rate of interest
permissible under law ("MAXIMUM LAWFUL RATE"), then so long as the Maximum
Lawful Rate would be so exceeded, the rate of interest payable hereunder will be
equal to the Maximum Lawful Rate; provided, that if at any time thereafter the
rate of interest payable hereunder is less than the Maximum Lawful Rate, Buyer
will continue to pay interest hereunder at the Maximum Lawful Rate until such
time as the total interest received by Europlay is equal to the total interest
that would have been received had the interest rate payable hereunder been (but
for the operation of this paragraph) the interest rate otherwise payable as
provided herein. Thereafter, interest hereunder will be paid at the rate of
interest and in the manner initially provided in the preceding paragraph, unless
and until the rate of interest again exceeds the Maximum Lawful Rate, and at
that time this paragraph will again apply. In no event will the total interest
received by Europlay pursuant to the terms hereof exceed the amount that
Europlay could lawfully have received had the interest due hereunder been
calculated for the full term hereof at the Maximum Lawful Rate.

            Section 2. PAYMENTS.

            (a) Buyer will pay the principal amount of this Note and all accrued
      and unpaid interest on the principal amount on the dates set forth on
      Schedule A (the date of the last such payment being the "MATURITY DATE").
      Buyer will also pay any costs, expenses, or other amounts due and payable
      hereunder on the Maturity Date.
<PAGE>
            (b) All payments of principal, interest, costs, expenses, and other
      amounts due and payable in respect of this Note will be delivered to
      Europlay at 21900 Burbank Blvd., Suite 270, Woodland Hills, California
      91367, or at such other address as Europlay may in writing notify Buyer.
      If payment on this Note is stated to be due on a day that is not a
      Business Day (as defined below), such payment will instead be made on the
      next Business Day, and such extension of time will be included in the
      computation of interest payable on this Note. "BUSINESS DAY" means any day
      other than a Saturday, Sunday or legal holiday under the laws of the State
      of California or any other day on which banking institutions located in
      such state are authorized or required by law or other governmental action
      to close. Each payment made prior to the Maturity Date hereunder will be
      credited first to any fees, costs, or other amounts due and payable to
      Europlay hereunder, second to interest then due, and the remainder of such
      payment will be credited to principal, and interest will thereupon cease
      to accrue upon the principal so credited. Each of Europlay and any
      subsequent holder of this Note agrees, by its acceptance hereof, that
      before disposing of this Note or any part hereof it will make a notation
      hereon of all principal payments previously made hereunder and of the date
      to which interest hereon has been paid; provided, however, that the
      failure to make a notation of any payment made on this Note will not limit
      or otherwise affect the obligation of Buyer hereunder with respect to
      payments of principal or interest on this Note.

            Section 3. VOLUNTARY PREPAYMENTS. Buyer will have the right at any
time and from time to time prior to the Maturity Date to prepay the principal of
this Note in whole or in part, without premium or penalty. Any prepayment
hereunder will be accompanied by interest on the principal amount of this Note
being prepaid to the date of prepayment as well as by any fees, costs, or other
amounts due and payable to Europlay hereunder.

            Section 4. SECURITY. This Note is being delivered by Buyer in
connection with the Payment Guaranty of even date herewith ("GUARANTY") of
Buyer's parent company, Infogrames Entertainment SA ("GUARANTOR").

            Section 5. EVENTS OF DEFAULT. The occurrence of any of the following
events will constitute an "EVENT OF DEFAULT":

            (a) failure of Buyer to pay any principal under this Note when due,
      whether at stated maturity or otherwise, or failure of Buyer to pay any
      interest or other amount due and payable under this Note within three days
      after the date due; or

            (b) (i) a court having jurisdiction in the premises enters a decree
      or order for relief in respect of Buyer in an involuntary case under Title
      11 of the United States Code entitled "BANKRUPTCY" (as now and hereinafter
      in effect, or any successor thereto, the "BANKRUPTCY CODE") or any
      applicable bankruptcy, insolvency or other similar law now or hereafter in
      effect, which decree or order is not stayed; or any other similar relief
      is granted under any applicable federal or state law; or (ii) an
      involuntary case is commenced against Buyer under any applicable
      bankruptcy, insolvency or other similar law now or hereafter in effect; or
      a decree or order of a court having jurisdiction in the premises for the
      appointment of a receiver, liquidator,


                                       2

      sequestrator, trustee, custodian or other officer having similar powers
      over Buyer or over all or a substantial part of its property has been
      entered; or the involuntary appointment of an interim receiver, trustee or
      other custodian of Buyer for all or a substantial part of its property has
      occurred; or a warrant of attachment, execution, or similar process will
      have been issued against any substantial part of the property of Buyer,
      and, in the case of any event described in this clause (ii), such event
      will have continued for 30 days unless dismissed, bonded or discharged; or

            (c) an order for relief has been entered with respect to Buyer or
      Buyer commences a voluntary case under the Bankruptcy Code or any
      applicable bankruptcy, insolvency or other similar law now or hereafter in

      case, or to the conversion of an involuntary case to a voluntary case,
      under any such law, or consents to the appointment of or taking possession
      by a receiver, trustee or other custodian for all or a substantial part of
      its property; or Buyer makes an assignment for the benefit of creditors;
      or

            (d) at any time after the date hereof, the Guaranty, or any other
      document delivered pursuant hereto or thereto will cease to be in full
      force and effect or will be declared null or void, or Buyer or Guarantor
      contests the validity or enforceability of this Note, the Guaranty, or any
      other document delivered pursuant hereto or thereto; or

            (e) any representation, warranty or statement made by the Buyer
      herein or by Guarantor in the Guaranty or any other document delivered
      pursuant hereto or thereto will prove to have been untrue in any material
      respect on the date as of which made or deemed made; or

            (f) the Buyer or Guarantor will default in the due performance or
      observance by it or them of any material term, covenant, or agreement
      applicable to it or them contained in this Note, the Guaranty, or any
      other document delivered pursuant hereto or thereto.

            Section 6. EUROPLAY REMEDIES. Upon the occurrence of any Event of
Default specified pursuant to Section 5(b) or Section 5(c), the outstanding
principal amount of this Note together with all accrued and unpaid interest

by law, hereby waives any right of set off, recoupment or similar remedies that
Buyer may now or hereafter have under applicable law.

            (a) Any notice or other communication provided for in this Note will
      be in writing and sent, if to Europlay to its principal offices at the
      address listed above or at such other address as Europlay may from time to
      time in writing designate and if to Buyer at the address listed on the
      signature page hereto or at such address as Buyer may from time to time in

            (b) No failure or delay on the part of Europlay to exercise any
      right, power, or privilege hereunder or under any document delivered

      therein, nor will any single or partial exercise of any such right, power,
      or privilege hereunder or under any document delivered pursuant hereto
      preclude any other or further exercise thereof or the exercise of any
      other right, power, or privilege. The rights and remedies expressly
      provided in this Note and any other document delivered pursuant hereto are
      cumulative to, and not exclusive of, any rights or remedies that Europlay
      would otherwise have.

            (c) If any provision in or obligation under this Note will be
      invalid, illegal or unenforceable in any jurisdiction, the validity,
      legality and enforceability of the remaining provisions or obligations, or
      of such provision or obligation in any other jurisdiction, will not in any
      way be affected or impaired thereby.

            (d) This Note will be binding upon Buyer and Europlay and their
      respective successors and assigns. None of the terms or provisions of this
      Note may be waived, altered, modified or amended except in writing duly

      employees, and representatives from and hold each of them harmless against
      any and all liabilities, obligations, losses, damages, penalties, claims,
      actions, judgments, suits, costs, expenses, and disbursements, including
      but not limited to the reasonable fees and disbursements of counsel,
      incurred by any of them in connection with any collection on or
      enforcement of this Note, including any action or proceeding by Europlay
      seeking relief from the automatic stay in any Bankruptcy, insolvency, or
      like proceeding instituted by or against Buyer (but excluding any such
      liabilities, obligations and losses, to the extent incurred by reason of
      the gross negligence or willful misconduct of Europlay or any other such
      indemnified party).
