                               RIGHTS AGREEMENT
 
  Agreement, dated as of May 13, 1999, between Softkey Software Products Inc.,
an Ontario corporation (the "Company"), Mattel, Inc., a Delaware corporation
("Mattel"), and CIBC Mellon Trust Company, a trust company incorporated under
the laws of Canada (the "Rights Agent").
 
  The Board of Directors of the Company has authorized the issuance of one
Exchangeable Share purchase right (a "Right") for each Exchangeable Share (as
hereinafter defined) of the Company outstanding as of the Close of Business
(as defined below) on the Effective Date (as hereinafter defined) (the "Record
Date"), each Right representing the right to purchase one Exchangeable Non-
Voting Share of the Company (an "Exchangeable Share"), and has further
authorized and directed the issuance of one Right with respect to each
Exchangeable Share that shall become outstanding between the Record Date and
the earliest of the Distribution Date, the Redemption Date and the Final
Expiration Date (as such terms are hereinafter defined), in each case, upon
the terms and subject to the conditions herein set forth.
 
  As provided in the Agreement and Plan of Merger dated as of December 13,
1998 (the "Merger Agreement"), between Mattel and The Learning Company, Inc.,
a Delaware corporation, the Rights are intended to provide rights to acquire
additional Exchangeable Shares (or in certain circumstances other securities)
on terms substantially the same as, and having an economically equivalent
value to, the Mattel Rights (as hereinafter defined).
 
  Accordingly, in consideration of the premises and the mutual agreements
herein set forth, the parties hereby agree as follows:
 
  Section 1. Certain Definitions. For the purposes of this Agreement, the
following terms have the meanings indicated:
 
  (a) "Acquiring Person" shall have the meaning ascribed to that term in the
      Mattel Rights Agreement.
 
  (b) "Affiliate" and "Associate" shall have the respective meanings ascribed
      to such terms in Rule 12b-2 of the General Rules and Regulations under
      the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
      as in effect on the date of this Agreement.
 
  (c) A Person shall be deemed the "Beneficial Owner" of and shall be deemed
      to "beneficially own" any securities:
 
      (i) which such Person or any of such Person's Affiliates or
    Associates beneficially owns, directly or indirectly;
 
      (ii) which such Person or any of such Person's Affiliates or
    Associates has (A) the right to acquire (whether such right is
    exercisable immediately or only after the passage of time) pursuant to
    any agreement, arrangement or understanding (other than customary
    agreements with and between underwriters and selling group members with
    respect to a bona fide public offering of securities), or upon the
    exercise of conversion rights, exchange rights, rights (other than
    these Rights or the Mattel Rights), warrants or options, or
    otherwise; provided, however, that a Person shall not be deemed the
    Beneficial Owner of, or to beneficially own, securities tendered
    pursuant to a tender or exchange offer made by or on behalf of such
    Person or any of such Person's Affiliates or Associates until such
    tendered securities are accepted for purchase or exchange; or (B) the
    right to vote pursuant to any agreement, arrangement or understanding;
    provided, however, that a Person shall not be
 
                                       1

 
    deemed the Beneficial Owner of, or to beneficially own, any security if
    the agreement, arrangement or understanding to vote such security
    arises solely from a revocable proxy or consent given to such Person in
    response to a public proxy or consent solicitation made generally to
    all holders of Exchangeable Shares pursuant to, and in accordance with,
    applicable rules and regulations; or
 
      (iii) which are beneficially owned, directly or indirectly, by any
    other Person with which such Person or any of such Person's Affiliates
    or Associates has any agreement, arrangement or understanding (other
    than customary agreements with and between underwriters and selling
    group members with respect to a bona fide public offering of
    securities) for the purpose of acquiring, holding, voting (except to
    the extent contemplated by the proviso to Section 1(c)(ii)(B)) or
    disposing of any securities of the Company or of Mattel.
 
      Notwithstanding anything in this definition of Beneficial Ownership
    to the contrary, the phrase "then outstanding", when used with
    reference to a Person's Beneficial Ownership of securities of the
    Company, shall mean the number of such securities then issued and
    outstanding together with the number of such securities not then
    actually issued and outstanding which such Person would be deemed to
    own beneficially hereunder. Any person who owns Exchangeable Shares
    shall be deemed to beneficially own the maximum number of Mattel Common
    Shares issuable to such holder upon the exchange, retraction or
    redemption of all such Exchangeable Shares at the measurement date.
 
  (d) "Business Day" shall mean any day other than a Saturday, a Sunday, or a
      day on which banking institutions in both the City of Toronto and the
      Commonwealth of Massachusetts or the State of California are authorized
      or obligated by law or executive order to close.
 
  (e) "Close of Business" on any given date shall mean 5:00 P.M., New York
      City time, on such date; provided, however, that if such date is not a
      Business Day it shall mean 5:00 P.M., New York City time, on the next
      succeeding Business Day.
 
  (f) "Common Shares" when used with reference to the Company shall mean the
      Exchangeable Shares of the Company or any other shares of capital stock
      of the Company or of Mattel into which the Exchangeable Shares may be
      reclassified or changed or exchanged. "Common Shares" when used with
      reference to any Person other than the Company shall mean the capital
      stock (or equity interest) with the greatest voting power of such other
      Person or, if such other Person is a Subsidiary of another Person, the
      Person or Persons which ultimately control such first-mentioned Person.
 
  (g) "Distribution Date" shall have the meaning ascribed to that term in the
      Mattel Rights Agreement.
 
  (h) "Exchangeable Share" shall have the meaning set forth in the
      introductory paragraph of this Rights Agreement.
 
  (i) "Effective Date" shall mean May 13, 1999.
 
  (j) "Final Expiration Date" shall have the meaning set forth in Section 7
      hereof.
 
  (k) "Mattel Common Shares" shall mean the shares of common stock, par value
      U.S. $1.00 per share, of Mattel.
 
  (l) "Mattel Preference Shares" shall mean shares of Series E Junior
      Participating Preference Stock, par value U.S. $.01 per share, of
      Mattel having the rights and preferences set forth in the Form of
      Certificate of Designations attached to the Mattel Rights Agreement as
      Exhibit A.
 
                                       2

 
  (m) "Mattel Rights" shall mean the Rights as defined in the Mattel Rights
      Agreement.
 
  (n) "Mattel Rights Agreement" shall mean the Rights Agreement dated as of
      February 7, 1992 between Mattel and The First National Bank of Boston,
      as Rights Agent, as amended from time to time, attached as Exhibit "C"
      hereto.
 
  (o) "Merger Agreement" shall have the meaning set forth in the second
      introductory paragraph of this Rights Agreement.
 
  (p) "Merger Exchange Ratio" shall mean 1.2 which is the "Exchange Ratio" as
      defined and determined in accordance with Section 2.7(a) of the Merger
      Agreement.
 
  (q) "Person" shall mean any individual, firm, corporation or other entity,
      and shall include any successor (by merger or otherwise) of such
      entity.
 
  (r) "Redemption Date" shall have the meaning set forth in Section 7 hereof.
 
  (s) "Subsidiary" of any Person shall mean any corporation or other entity
      of which a majority of the voting power of the voting equity securities
      or equity interest is owned, directly or indirectly, by such Person.
 
  Section 2. Appointment of Rights Agent. The Company hereby appoints the
Rights Agent to act as agent for the Company and the holders of the Rights
(who, in accordance with Section 3 hereof, shall prior to the Distribution Date
also be the holders of the Exchangeable Shares) in accordance with the terms
and conditions hereof, and the Rights Agent hereby accepts such appointment.
The Company may from time to time appoint such co-Rights Agents as it may deem
necessary or desirable subject to the approval of the Rights Agent, which
approval shall not be unreasonably withheld.
 
  Section 3. Issue of Right Certificates.
 
  (a) Until the Distribution Date, (x) the Rights will be evidenced (subject
      to the provisions of Section 3(b) hereof) by the certificates for
      Exchangeable Shares registered in the names of the holders thereof
      (which certificates shall also be deemed to be Right Certificates) and
      not by separate Right Certificates, and (y) the right to receive Right
      Certificates will be transferable only in connection with the transfer
      of the associated Exchangeable Shares. As soon as practicable after the
      Distribution Date, the Company will prepare and execute, the Rights
      Agent will countersign, and the Company will send or cause to be sent
      (and the Rights Agent will, if requested, send) by first-class,
      insured, postage-prepaid mail, to each record registered holder of
      Exchangeable Shares as of the Close of Business on the Distribution
      Date, at the address of such holder shown on the records of the
      Company, a Right Certificate, in substantially the form of Exhibit A
      hereto (a "Right Certificate"), evidencing one Right for each
      Exchangeable Share so held. As of the Distribution Date, the Rights
      will be evidenced solely by such Right Certificates.
 
  (b) On the Record Date, or as soon as practicable thereafter, the Company
      will send (and the Rights Agent, will, if requested, send) a copy of a
      Summary of Rights to Purchase Exchangeable Shares, in substantially the
      form of Exhibit B hereto (the "Summary of Rights"), by first-class,
      postage-prepaid mail, to each registered holder of Exchangeable Shares
      as of the Close of Business on the Record Date, at the address of such
      holder shown on the records of the Company. With respect to
      certificates for Exchangeable Shares outstanding as of the Record Date,
      until the Distribution Date, the associated Rights will be evidenced by
      such certificates registered in the names of the holders thereof
      together with a
 
                                       3

 
     copy of the Summary of Rights. Until the Distribution Date (or the
     earlier of the Redemption Date or the Final Expiration Date), the
     surrender for transfer of any certificate for Exchangeable Shares
     outstanding on the Record Date, with or without a copy of the Summary of
     Rights, shall also constitute the transfer of the Rights associated with
     the Exchangeable Shares represented thereby.
 
  (c) Certificates for Exchangeable Shares which become outstanding after the
      Record Date but prior to the earliest of the Distribution Date, the
      Redemption Date or the Final Expiration Date shall have impressed on,
      printed on, written on or otherwise affixed to them the following
      legend:
 
      This certificate also evidences and entitles the holder hereof
      to certain rights as set forth in a Rights Agreement between
      Softkey Software Products Inc., Mattel, Inc. and CIBC Mellon
      Trust Company, dated as of May 13, 1999 (the "Rights
      Agreement"), the terms of which are hereby incorporated herein
      by reference and a copy of which is on file at the registered
      office of Softkey Software Products Inc. Under certain
      circumstances, as set forth in the Rights Agreement, such
      Rights will be evidenced by separate certificates and will no
      longer be evidenced by this certificate. Softkey Software
      Products Inc. will mail to the holder of this certificate a
      copy of the Rights Agreement without charge after receipt of a
      written request therefor. Under certain circumstances, as set
      forth in the Rights Agreement, Rights issued to any Person who
      becomes an Acquiring Person (as defined in the Rights
      Agreement) may become null and void.
 
    With respect to such certificates containing the foregoing legend,
    until the Distribution Date, the Rights associated with the
    Exchangeable Shares represented by such certificates shall be evidenced
    by such certificates alone, and the surrender for transfer of any such
    certificate shall also constitute the transfer of the Rights associated
    with the Exchangeable Shares represented thereby. In the event that the
    Company or Mattel or any subsidiary of Mattel or any Person directly or
    indirectly controlled by or under common control of Mattel beneficially
    owns, purchases or otherwise acquires any Exchangeable Shares prior to
    the Distribution Date, for so long as such Exchangeable Shares are
    beneficially owned by any such entity or Person, any Rights associated
    with such Exchangeable Shares shall be deemed cancelled and retired and
    such entity or Person shall not be entitled to exercise any Rights
    associated with such Exchangeable Shares. Certificates for Exchangeable
    Shares which become outstanding after the Record Date, but prior to the
    earliest of the Distribution Date, the Redemption Date or the Final
    Expiration Date shall evidence one Right for each Exchangeable Share
    evidenced thereby, notwithstanding the absence of the foregoing
    legend.
 
  Section 4. Form of Right Certificates. The Right Certificates (and the forms
of election to purchase Exchangeable Shares and of assignment to be printed on
the reverse thereof) shall be substantially the same as Exhibit A hereto and
may have such marks of identification or designation and such legends,
summaries or endorsements printed thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this Agreement, or as may be
required to comply with any applicable law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any stock exchange on which
the Rights may from time to time be listed, or to conform to usage. Subject to
the provisions of Section 22 hereof, the Right Certificates shall entitle the
holders thereof to purchase such number of Exchangeable Shares as shall be set
forth therein at the
 
                                       4

 
price per Exchangeable Share set forth therein (the "Purchase Price"), but the
number of such Exchangeable Shares and the Purchase Price shall be subject to
adjustment as provided herein.
 
  Section 5. Countersignature and Registration.
 
  (a) The Right Certificates shall be executed on behalf of the Company by
      the Chairman of the Board of Directors, the President, any of the Vice
      Presidents, the Treasurer or the Controller of the Company, either
      manually or by facsimile signature, shall have affixed thereto the
      Company's seal or a facsimile thereof, and shall be attested by the
      Secretary or an Assistant Secretary of the Company, either manually or
      by facsimile signature. The Right Certificates shall be countersigned
      (manually or by facsimile signature in a manner satisfactory to the
      Company) by the Rights Agent and shall not be valid for any purpose
      unless countersigned. In case any officer of the Company who shall have
      signed any of the Right Certificates shall cease to be such officer of
      the Company before countersignature by the Rights Agent and issuance
      and delivery by the Company, such Right Certificates, nevertheless, may
      be countersigned by the Rights Agent and issued and delivered by the
      Company with the same force and effect as though the Person who signed
      such Right Certificates had not ceased to be such officer of the
      Company; and any Right Certificate may be signed on behalf of the
      Company by any Person who, at the actual date of execution of such
      Right Certificate, shall be a proper officer of the Company to sign
      such Right Certificate, although at the date of the execution of this
      Rights Agreement by any such Person was not such an officer.
 
  (b) Following the Distribution Date, the Rights Agent will keep or cause to
      be kept, at an office or agency designated for such purpose, books for
      registration and transfer of the Right Certificates issued hereunder.
      Such books shall show the names and addresses of the respective holders
      of the Right Certificates, the number of Rights evidenced on its face
      by each of the Right Certificates and the date of each of the Right
      Certificates.
 
  Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.
 
  (a) Subject to the provisions of Section 14 hereof, at any time after the
      Close of Business on the Distribution Date, and at or prior to the
      Close of Business on the earlier of the Redemption Date or the Final
      Expiration Date, any Right Certificate or Right Certificates (other
      than Right Certificates representing Rights that have become void
      pursuant to Section 11(a)(ii) hereof or that have been exchanged
      pursuant to Section 24 hereof) may be transferred, split up, combined
      or exchanged for another Right Certificate or Right Certificates,
      entitling the registered holder to purchase a like number of
      Exchangeable Shares as the Right Certificate or Right Certificates
      surrendered then entitled such holder to purchase. Any registered
      holder desiring to transfer, split up, combine or exchange any Right
      Certificate or Right Certificates shall make such request in writing
      delivered to the Rights Agent, and shall surrender the Right
      Certificate or Right Certificates to be transferred, split up, combined
      or exchanged at the office or agency of the Rights Agent designated for
      such purpose. Thereupon the Rights Agent shall countersign and deliver
      to the Person entitled thereto a Right Certificate or Right
      Certificates, as the case may be, as so requested. The Company may
      require payment of a sum sufficient to cover any tax or governmental
      charge that may be imposed in connection with any transfer, split up,
      combination or exchange of Right Certificates.
 
  (b) Upon receipt by the Company and the Rights Agent of evidence reasonably
      satisfactory to them of the loss, theft, destruction or mutilation of a
      Right Certificate, and, in case of loss, theft or destruction, of
      indemnity or security reasonably satisfactory to them, and, at the
 
                                       5

 
     Company's request, reimbursement to the Company and the Rights Agent of
     all reasonable expenses incidental thereto, and upon surrender to the
     Rights Agent and cancellation of the Right Certificate if mutilated, the
     Company will make and deliver a new Right Certificate of like tenor to
     the Rights Agent for delivery to the registered holder in lieu of the
     Right Certificate so lost, stolen, destroyed or mutilated.
 
  Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights.
 
  (a) The registered holder of any Right Certificate may exercise the Rights
      evidenced thereby (except as otherwise provided herein) in whole or in
      part, upon surrender of the Right Certificate, with the form of
      election to purchase on the reverse side thereof duly executed, to the
      Rights Agent at the office or agency of the Rights Agent designated for
      such purpose, together with payment of the Purchase Price for each
      Exchangeable Share as to which the Rights are exercised, at any time
      which is both after the Distribution Date and prior to the earliest of
      (i) the Close of Business on February 17, 2002 (the "Final Expiration
      Date"), (ii) the time at which the Rights are redeemed as provided in
      Section 23 hereof (the "Redemption Date"), or (iii) the time at which
      such Rights are exchanged as provided in Section 24 hereof.
 
  (b) The Purchase Price for each Exchangeable Share purchasable pursuant to
      the exercise of a Right shall initially be an amount equal to U.S. $150
      multiplied by the Merger Exchange Ratio, and shall be subject to
      adjustment from time to time as provided in Sections 11 and 13 hereof
      and shall be payable in lawful money of the United States of America in
      accordance with paragraph (c) of this Section 7.
 
  (c) Upon receipt of a Right Certificate representing exercisable Rights,
      with the form of election to purchase duly executed, accompanied by
      payment of the Purchase Price for the Exchangeable Shares to be
      purchased and an amount equal to any applicable transfer tax required
      to be paid by the holder of such Right Certificate in accordance with
      Section 9 hereof by certified check, cashier's check or money order
      payable to the order of the Company, the Rights Agent shall thereupon
      promptly (i) requisition from any transfer agent of the Exchangeable
      Shares certificates for the number of Exchangeable Shares to be
      purchased and the Company hereby irrevocably authorizes its transfer
      agent to comply with all such requests, (ii) when appropriate,
      requisition from the Company the amount of cash to be paid in lieu of
      issuance of fractional shares in accordance with Section 14 hereof,
      (iii) after receipt of such certificates, cause the same to be
      delivered to or upon the order of the registered holder of such Right
      Certificate, registered in such name or names as may be designated by
      such holder, (iv) when appropriate, after receipt, deliver such cash to
      or upon the order of the registered holder of such Right Certificate,
      and (v) tender to the Company all payments received on exercise of
      Rights.
 
  (d) In case the registered holder of any Right Certificate shall exercise
      less than all the Rights evidenced thereby, a new Right Certificate
      evidencing Rights equivalent to the Rights remaining unexercised shall
      be issued by the Rights Agent to the registered holder of such Right
      Certificate or to his duly authorized assigns, subject to the
      provisions of Section 14 hereof.
 
  Section 8. Cancellation and Destruction of Right Certificates. All Right
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right
 
                                       6

 
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Rights Agreement. The Company shall deliver to
the Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall
deliver all cancelled Right Certificates to the Company, or shall, at the
written request of the Company, destroy such cancelled Right Certificates, and
in such case shall deliver a certificate of destruction thereof to the Company.
 
  Section 9. Availability of Exchangeable Shares.
 
  (a) The Company covenants and agrees that it will cause to be reserved and
      kept available out of its authorized and unissued Exchangeable Shares
      or any Exchangeable Shares held in its treasury, the number of
      Exchangeable Shares that will be sufficient to permit the exercise in
      full of all outstanding Rights in accordance with Section 7 hereof.
 
  (b) The Company covenants and agrees that it will take all such action as
      may be necessary to ensure that all Exchangeable Shares delivered upon
      exercise of Rights shall, at the time of delivery of the certificates
      for such Exchangeable Shares (subject to payment of the Purchase
      Price), be duly and validly authorized and issued and fully paid and
      non-assessable shares.
 
  (c) The Company further covenants and agrees that it will pay when due and
      payable any and all United States and Canadian federal, state and
      provincial transfer taxes and charges which may be payable in respect
      of the issuance or delivery of the Right Certificates or of any
      Exchangeable Shares upon the exercise of Rights. The Company shall not,
      however, be required to pay any transfer tax which may be payable in
      respect of any transfer or delivery of Right Certificates to a Person
      other than, or the issuance or delivery of certificates for the
      Exchangeable Shares in a name other than that of, the registered holder
      of the Right Certificate evidencing Rights surrendered for exercise or
      to issue or to deliver any certificates for Exchangeable Shares upon
      the exercise of any Rights until any such tax shall have been paid (any
      such tax being payable by the holder of such Right Certificate at the
      time of surrender) or until it has been established to the Company's
      reasonable satisfaction that no such tax is due.
 
  Section 10. Exchangeable Shares Record Date. Each Person in whose name any
certificate for Exchangeable Shares is issued and registered upon the exercise
of Rights shall for all purposes be deemed to have become the holder of record
of the Exchangeable Shares represented thereby on, and such certificate shall
be dated, the date upon which the Right Certificate evidencing such Rights was
duly surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Exchangeable Shares transfer books of the
Company are closed, such Person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the Exchangeable Shares transfer books of the
Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Right Certificate shall not be entitled to any rights of a holder
of Exchangeable Shares for which the Rights shall be exercisable, including,
without limitation, any right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled
to receive any notice of any proceedings of the Company, except as provided
herein.
 
                                       7

 
  Section 11. Adjustment of Purchase Price, Number of Shares or Number of
Rights. The Purchase Price, the number of Exchangeable Shares covered by each
Right and the number of Rights outstanding are subject to adjustment from time
to time as provided in this Section 11.
 
  (a) (i) In the event the Company shall at any time after the date of this
      Agreement (A) declare a dividend on the Exchangeable Shares payable in
      Exchangeable Shares, (B) subdivide the outstanding Exchangeable Shares,
      (C) combine the outstanding Exchangeable Shares into a smaller number
      of Exchangeable Shares or (D) issue any shares of its capital stock in
      a reclassification of the Exchangeable Shares (including any such
      reclassification in connection with a consolidation or merger in which
      the Company is the continuing or surviving corporation), except as
      otherwise provided in this Section 11(a), the Purchase Price in effect
      at the time of the record date for such dividend or of the effective
      date of such subdivision, combination or reclassification, and the
      number and kind of shares of capital stock issuable on such date, shall
      be proportionately adjusted so that the holder of any Right exercised
      after such time shall be entitled to receive the aggregate number and
      kind of shares of capital stock which, if such Right had been exercised
      immediately prior to such date and at a time when the Exchangeable
      Shares transfer books of the Company were open, he would have owned
      upon such exercise and been entitled to receive by virtue of such
      dividend, subdivision, combination or reclassification;
 
    (ii) Subject to Section 24 of this Agreement, in the event any Person
    becomes an Acquiring Person, (A) the Company shall provide notice
    thereof to the Rights Agent, including the name of the Acquiring Person
    and any Associates and Affiliates of the Acquiring Person known to the
    Company, and (B) each holder of a Right (other than any Rights that are
    or were acquired or beneficially owned by any Acquiring Person or by
    any Associate or Affiliate of any Acquiring Person) shall thereafter
    have a right to receive, upon exercise thereof at a price equal to the
    then current Purchase Price multiplied by the number of Exchangeable
    Shares for which a Right is then exercisable, in accordance with the
    terms of this Agreement and in lieu of such number of Exchangeable
    Shares, such other number of Exchangeable Shares of the Company as
    shall equal the result obtained by (x) multiplying the then current
    Purchase Price by the number of Exchangeable Shares for which a Right
    is then exercisable and dividing that product by (y) 50% of the then
    current per share market price of the Exchangeable Shares (determined
    pursuant to Section 11(d) hereof) on the date of the occurrence of such
    event. From and after the occurrence of such event, any Rights that are
    or were acquired or beneficially owned by an Acquiring Person (or any
    Associate or Affiliate of any Acquiring Person) shall be void and any
    holder of such Rights shall thereafter have no right to exercise such
    Rights under any provision of this Agreement. No Right Certificate
    shall be issued pursuant to Section 3 that represents Rights
    beneficially owned by an Acquiring Person whose Rights would be void
    pursuant to the preceding sentence or any Associate or Affiliate
    thereof; no Right Certificate shall be issued at any time upon the
    transfer of any Rights to an Acquiring Person whose Rights would be
    void pursuant to the preceding sentence or any Associate or Affiliate
    thereof or to any nominee of such Acquiring Person, Associate or
    Affiliate; and any Right Certificate delivered to the Rights Agent for
    transfer to an Acquiring Person whose Rights would be void pursuant to
    the preceding sentence or any Associate or Affiliate thereof shall be
    cancelled. In the event that any Person shall become an Acquiring
    Person and any Rights shall then be outstanding, the Company shall not
    take any action which would eliminate or diminish the benefits intended
    to be afforded by the Rights.
 
                                       8

 
    The Rights Agent shall not be under any responsibility to ascertain the
    existence of facts as to whether any Rights are or were acquired or
    owned or beneficially owned by an Acquiring Person (or any Associate or
    Affiliate or nominee of any Acquiring Person) or transferred to
    an Acquiring Person (or any Associate or Affiliate or nominee of any
    Acquiring Person) but shall proceed only upon receipt of a written
    notice from the Company.
 
    (iii) In the event that there shall not be sufficient Exchangeable
    Shares issued but not outstanding or authorized but unissued to permit
    the exercise in full of the Rights in accordance with the foregoing
    subparagraph (ii), the Company shall take all such action as may be
    necessary to authorize additional Exchangeable Shares for issuance upon
    exercise of the Rights.
 
  (b) In case the Company shall fix a record date for the issuance of rights,
      options or warrants to all holders of Exchangeable Shares entitling
      them (for a period expiring within 45 calendar days after such record
      date) to subscribe for or purchase Exchangeable Shares (or shares
      having the same rights, privileges and preferences as the Exchangeable
      Shares ("equivalent exchangeable shares")) or securities convertible
      into Exchangeable Shares or equivalent exchangeable shares at a price
      per Exchangeable Share or equivalent exchangeable share (or having a
      conversion price per share, if a security convertible into Exchangeable
      Shares or equivalent exchangeable shares) less than the then current
      per share market price of the Exchangeable Shares (determined pursuant
      to Section 11(d) hereof) on such record date, the Purchase Price to be
      in effect after such record date shall be determined by multiplying the
      Purchase Price in effect immediately prior to such record date by a
      fraction, the numerator of which shall be the number of Exchangeable
      Shares and equivalent exchangeable shares outstanding on such record
      date plus the number of Exchangeable Shares and equivalent exchangeable
      shares which the aggregate offering price of the total number of
      Exchangeable Shares and/or equivalent exchangeable shares so to be
      offered (and/or the aggregate initial conversion price of the
      convertible securities so to be offered) would purchase at such current
      market price and the denominator of which shall be the number of
      Exchangeable Shares and equivalent exchangeable shares outstanding on
      such record date plus the number of additional Exchangeable Shares
      and/or equivalent exchangeable shares to be offered for subscription or
      purchase (or into which the convertible securities so to be offered are
      initially convertible). In case such subscription price may be paid in
      a consideration part or all of which shall be in a form other than
      cash, the value of such consideration shall be as determined in good
      faith by the Board of Directors of the Company, whose determination
      shall be described in a statement filed with the Rights Agent.
      Exchangeable Shares and equivalent exchangeable shares owned by or held
      for the account of the Company or Mattel (or any subsidiary thereof or
      any person directly or indirectly controlled by or under common control
      of Mattel) shall not be deemed outstanding for the purpose of any such
      computation. Such adjustment shall be made successively whenever such a
      record date is fixed; and in the event that such rights, options or
      warrants are not so issued, the Purchase Price shall be adjusted to be
      the Purchase Price which would then be in effect if such record date
      had not been fixed.
 
  (c) In case the Company shall fix a record date for the making of a
      distribution to all holders of the Exchangeable Shares (including any
      such distribution made in connection with a consolidation or merger in
      which the Company is the continuing or surviving corporation) of
      evidences of indebtedness or assets (other than a regular quarterly
      cash dividend or a dividend payable in Exchangeable Shares) or
      subscription rights or warrants (excluding those referred to in Section
      11(b) hereof), the Purchase Price to be in effect after such
 
                                       9

 
     record date shall be determined by multiplying the Purchase Price in
     effect immediately prior to such record date by a fraction, the
     numerator of which shall be the then current per share market price of
     the Exchangeable Shares (determined pursuant to Section 11(d) hereof) on
     such record date, less the fair market value (as determined in good
     faith by the Board of Directors of the Company, whose determination
     shall be described in a statement filed with the Rights Agent) of the
     portion of the assets or evidences of indebtedness so to be distributed
     or of such subscription rights or warrants applicable to one
     Exchangeable Share and the denominator of which shall be such current
     per share market price (determined pursuant to Section 11(d) hereof) of
     the Exchangeable Shares. Such adjustments shall be made successively
     whenever such a record date is fixed; and in the event that such
     distribution is not so made, the Purchase Price shall again be adjusted
     to be the Purchase Price which would then be in effect if such record
     date had not been fixed.
 
  (d) (i) For the purpose of any computation hereunder, the "current per
      share market price" of any security (a "Security" for the purpose of
      this Section 11(d)(i)) on any date shall be deemed to be the average of
      the daily closing prices per share of such Security for the 30
      consecutive Trading Days (as such term is hereinafter defined)
      immediately prior to such date; provided, however, that in the event
      that the current per share market price of the Security is determined
      during a period following the announcement by the issuer of such
      Security of (A) a dividend or distribution on such Security payable in
      shares of such Security or securities convertible into such shares, or
      (B) any subdivision, combination or reclassification of such Security
      and prior to the expiration of 30 Trading Days after the ex-dividend
      date for such dividend or distribution, or the record date for such
      subdivision, combination or reclassification, then, and in each such
      cause, the current per share market price shall be appropriately
      adjusted to reflect the current market price per share equivalent of
      such Security. The closing price for each day shall be the last sale
      price, regular way, or, in case no such sale takes place on such day,
      the average of the closing bid and asked prices, regular way, in either
      case as reported in the principal consolidated transaction reporting
      system with respect to securities listed or admitted to trading on the
      New York Stock Exchange or, if the Security is not listed or admitted
      to trading on the New York Stock Exchange, as reported in the principal
      consolidated transaction reporting system with respect to securities
      listed on the principal national securities exchange on which the
      Security is listed or admitted to trading or, if the Security is not
      listed or admitted to trading on any national securities exchange, the
      last quoted price or, if not so quoted, the average of the high bid and
      low asked prices in the over-the-counter market, as reported by the
      National Association of Securities Dealers, Inc. Automated Quotations
      System ("NASDAQ") or such other system then in use, or, if on any such
      date the Security is not quoted by any such organization, the average
      of the closing bid and asked prices as furnished by a professional
      market maker making a market in the Security selected by the Board of
      Directors of the Company. The term "Trading Day" shall mean a day on
      which the principal national securities exchange on which the Security
      is listed or admitted to trading is open for the transaction of
      business or, if the Security is not listed or admitted to trading on
      any national securities exchange, a Business Day.
 
    (ii) For the purpose of any computation hereunder, the "current per
    share market price" of the Exchangeable Shares shall be determined in
    accordance with the method set forth in Section 11(d)(i). If the
    Exchangeable Shares are not publicly traded, the "current per share
    market price" of the Exchangeable Shares shall be conclusively deemed
    to be an amount equal to (A) the current per share market price of the
    Mattel Common Shares as determined
 
                                       10

 
    pursuant to Section 11(d)(i) (appropriately adjusted to reflect any
    stock split, stock dividend or similar transaction occurring after the
    date hereof), multiplied by (B) the Merger Exchange Ratio. If neither
    the Mattel Common Shares nor the Exchangeable Shares are publicly held
    or so listed or traded, "current per share market price" shall mean the
    fair value per share as determined in good faith by the Board of
    Directors of the Company, whose determination shall be described in a
    statement filed with the Rights Agent.
 
  (e) No adjustment in the Purchase Price shall be required unless such
      adjustment would require an increase or decrease of at least 1% in the
      Purchase Price; provided, however, that any adjustments which by reason
      of this Section 11(e) are not required to be made shall be carried
      forward and taken into account in any subsequent adjustment. All
      calculations under this Section 11 shall be made to the nearest cent or
      to the nearest one ten-thousandth of an Exchangeable Share or of any
      other share or security as the case may be. Notwithstanding the first
      sentence of this Section 11(e), any adjustment required by this Section
      11 shall be made no later than the earlier of (i) three years from the
      date of the transaction which requires such adjustment or (ii) the date
      of the expiration of the right to exercise any Rights.
 
  (f) If as a result of an adjustment made pursuant to Section 11(a) hereof,
      the holder of any Right thereafter exercised shall become entitled to
      receive any shares of capital stock of the Company other than
      Exchangeable Shares, thereafter the number of such other shares so
      receivable upon exercise of any Right shall be subject to adjustment
      from time to time in a manner and on terms as nearly equivalent as
      practicable to the provisions with respect to the Exchangeable Shares
      contained in Section 11 (a) through (c), inclusive, and the provisions
      of Sections 7, 9, 10 and 13 with respect to the Exchangeable Shares
      shall apply on like terms to any such other shares.
 
  (g) All Rights originally issued by the Company subsequent to any
      adjustment made to the Purchase Price hereunder shall evidence the
      right to purchase, at the adjusted Purchase Price, the number of
      Exchangeable Shares purchasable from time to time hereunder upon
      exercise of the Rights, all subject to further adjustment as provided
      herein.
 
  (h) Unless the Company shall have exercised its election as provided in
      Section 11 (i), upon each adjustment of the Purchase Price as a result
      of the calculations made in Sections 11(b) and (c), each Right
      outstanding immediately prior to the making of such adjustment shall
      thereafter evidence the right to purchase, at the adjusted Purchase
      Price, that number of Exchangeable Shares (calculated to the nearest
      one ten-thousandth of an Exchangeable Share) obtained by
      (i) multiplying (x) the number of shares covered by a Right immediately
      prior to this adjustment by (y) the Purchase Price in effect
      immediately prior to such adjustment of the Purchase Price and (ii)
      dividing the product so obtained by the Purchase Price in effect
      immediately after such adjustment of the Purchase Price.
 
  (i) The Company may elect on or after the date of any adjustment of the
      Purchase Price to adjust the number of Rights, in substitution for any
      adjustment in the number of Exchangeable Shares purchasable upon the
      exercise of a Right. Each of the Rights outstanding after such
      adjustment of the number of Rights shall be exercisable for the number
      of Exchangeable Shares for which a Right was exercisable immediately
      prior to such adjustment. Each Right held of record prior to such
      adjustment of the number of Rights shall become that number of Rights
      (calculated to the nearest one ten-thousandth) obtained by dividing the
      Purchase Price in effect immediately prior to adjustment of the
      Purchase Price by the Purchase Price in effect immediately after
      adjustment of the Purchase Price. The Company shall make a public
      announcement of its election to adjust the number
 
                                       11

 
     of Rights, indicating the record date for the adjustment, and, if known
     at the time, the amount of the adjustment to be made. This record date
     may be the date on which the Purchase Price is adjusted or any day
     thereafter, but, if the Right Certificates have been issued, shall be at
     least 10 days later than the date of the public announcement. If Right
     Certificates have been issued, upon each adjustment of the number of
     Rights pursuant to this Section 11(i), the Company shall, as promptly as
     practicable, cause to be distributed to holders of record of Right
     Certificates on such record date Right Certificates evidencing, subject
     to Section 14 hereof, the additional Rights to which such holders shall
     be entitled as a result of such adjustment, or, at the option of the
     Company, shall cause to be distributed to such holders of record in
     substitution and replacement of the Right Certificates held by such
     holders prior to the date of adjustment, and upon surrender thereof, if
     required by the Company, new Right Certificates so to be distributed
     shall be issued, executed and countersigned in the manner provided for
     herein and shall be registered in the names of the holders of record of
     Right Certificates on the record date specified in the public
     announcement.
 
  (j) Irrespective of any adjustment or change in the Purchase Price or the
      number of Exchangeable Shares issuable upon the exercise of the Rights,
      the Right Certificates theretofore and thereafter issued may continue
      to express the Purchase Price and the number of Exchangeable Shares
      which were expressed in the initial Right Certificates issued
      hereunder.
 
  (k) Before taking any action that would cause an adjustment reducing the
      Purchase Price below the then par value, if any, of the Exchangeable
      Shares or other shares of capital stock issuable upon exercise of the
      Rights, the Company shall take any corporate action which may, in the
      opinion of its counsel, be necessary in order that the Company may
      validly and legally issue fully paid and nonassessable Exchangeable
      Shares or other such shares at such adjusted Purchase Price.
 
  (l) In any case in which this Section 11 shall require that an adjustment
      in the Purchase Price be made effective as of a record date for a
      specified event, the Company may elect to defer until the occurrence of
      such event the issuing to the holder of any Right exercised after such
      record date of the Exchangeable Shares and other capital stock or
      securities of the Company, if any, issuable upon such exercise over and
      above the Exchangeable Shares and other capital stock or securities of
      the Company if any, issuable upon such exercise on the basis of the
      Purchase Price in effect prior to such adjustment; provided, however,
      that the Company shall deliver to such holder a due bill or other
      appropriate instrument evidencing such holder's right to receive such
      additional shares upon the occurrence of the event requiring such
      adjustment.
 
  (m) Anything in this Section 11 to the contrary notwithstanding, the
      Company shall be entitled to make such reductions in the Purchase
      Price, in addition to those adjustments expressly required by this
      Section 11, as and to the extent that it in its sole discretion shall
      determine to be advisable in order that any consolidation or
      subdivision of the Exchangeable Shares, issuance wholly for cash of any
      Exchangeable Shares at less than the current market price, issuance
      wholly for cash of Exchangeable Shares or securities which by their
      terms are convertible into or exchangeable for Exchangeable Shares,
      dividends on Exchangeable Shares payable in Exchangeable Shares or
      issuance of rights, options or warrants referred to herein above in
      Section 11(b), hereafter made by the Company to holders of its
      Exchangeable Shares shall not be taxable to such stockholders.
 
 
                                       12

 
  Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the
Exchangeable Shares a copy of such certificate and (c) mail a brief summary
thereof to each holder of a Right Certificate in accordance with Section 25
hereof. The Rights Agent shall be fully protected in acting and relying on any
such certificate and on any adjustment therein contained and shall not be
deemed to have knowledge of any such adjustment unless and until it shall have
received such certificate.
 
  Section 13. Consolidation, Merger or Sale or Transfer of Assets or Earning
Power.  In the event, directly or indirectly, at any time after any Person has
become an Acquiring Person, (a) Mattel shall consolidate with, or merge with
and into, any other Person, (b) any Person shall consolidate with Mattel or
merge with and into Mattel and Mattel shall be the continuing or surviving
corporation of such merger and, in connection with such merger, all or part of
the Mattel Common Shares shall be changed into or exchanged for stock or other
securities of any other Person (or Mattel) or cash or any other property, or
(c) Mattel shall sell or otherwise transfer (or one or more of its Subsidiaries
shall sell or otherwise transfer), in one or more transactions, assets or
earning power aggregating 50% or more of the assets or earning power to Mattel
and its Subsidiaries (taken as a whole) to any other Person other than Mattel
or one or more of its wholly-owned Subsidiaries, then, and in each such case,
proper provision shall be made so that (i) each holder of a Right (except as
otherwise provided herein) shall thereafter have the right to receive, upon the
exercise thereof at a price equal to the then current Purchase Price multiplied
by the number of Exchangeable Shares for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Exchangeable Shares,
such number of Common Shares of such other Person (including Mattel, as
successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of
Exchangeable Shares for which a Right is then exercisable and dividing that
product by (B) 50% of the then current per share market price of the Common
Shares of such other Person (determined pursuant to the Section 11(d) hereof)
on the date of consummation of such consolidation, merger, sale or transfer;
(ii) the issuer of such Common Shares shall thereafter be liable for, and shall
assume, by virtue of such consolidation, merger, sale or transfer, all the
obligations and duties of Mattel pursuant to this Agreement (iii) the term
"Mattel" shall thereafter be deemed to refer to such issuer; and (iv) such
issuer shall take such steps (including, but not limited to, the reservation of
a sufficient number of its Common Shares in accordance with Section 9 hereof)
in connection with such consummation as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to the Common Shares thereafter deliverable upon the exercise
of the Rights. Mattel shall not consummate any such consolidation, merger, sale
or transfer unless prior thereto the Company, Mattel and such issuer shall have
executed and delivered to the Rights Agent a supplemental agreement so
providing. Mattel shall not enter into any transaction of the kind referred to
in this Section 13 if at the time of such transaction there are any rights,
warrants, instruments or securities outstanding or any agreements or
arrangements which, as a result of the consummation of such transaction, would
eliminate or substantially diminish the benefits intended to be afforded by the
Rights. The provisions of this Section 13 shall similarly apply to successive
mergers or consolidations or sales or other transfers.
 
  Section 14. Fractional Rights and Fractional Shares.
 
  (a) The Company shall not be required to issue fractions of Rights or to
      distribute Right Certificates which evidence fractional Rights. In lieu
      of such fractional Rights, there shall be
 
                                       13

 
     paid to the registered holders of the Right Certificates with regard to
     which such fractional Rights would otherwise be issuable, an amount in
     cash equal to the same fraction of the current market value of a whole
     Right. For the purposes of this Section 14(a), the current market value
     of a whole Right shall be the closing price of the Rights for the
     Trading Day immediately prior to the date on which such fractional
     Rights would have been otherwise issuable. The closing price for any day
     shall be the last sale price, regular way, or, in case no such sale
     takes place on such day, the average of the closing bid and asked
     prices, regular way, in either case as reported in the principal
     consolidated transaction reporting system with respect to securities
     listed or admitted to trading on the New York Stock Exchange or, if the
     Rights are not listed or admitted to trading on the New York Stock
     Exchange, as reported in the principal consolidated transaction
     reporting system with respect to securities listed on the principal
     national securities exchange on which the Rights are listed or admitted
     to trading or, if the Rights are not listed or admitted to trading on
     any national securities exchange, the last quoted price or, if not so
     quoted, the average of the high bid and low asked prices in the over-
     the-counter market, as reported by NASDAQ or such other system then in
     use or, if any such date the Rights are not quoted by any such
     organization, the average of the closing bid and asked prices as
     furnished by a professional market maker making a market in the Rights
     selected by the Board of Directors of the Company. If on any such date
     no such market maker is making a market in the Rights, the fair value of
     the Rights on such date as determined in good faith by the Board of
     Directors of the Company shall be used.
 
  (b) The Company shall not be required to issue fractions of Exchangeable
      Shares upon exercise of the Rights or to distribute certificates which
      evidence fractional Exchangeable Shares. In lieu of fractional
      Exchangeable Shares, the Company shall pay to the registered holders of
      Right Certificates at the time such Rights are exercised as herein
      provided an amount in cash equal to the same fraction of the current
      market value of one Exchangeable Share. For the purposes of this
      Section 14(b), the current market value of an Exchangeable Share shall
      be the closing price of an Exchangeable Share (as determined pursuant
      to the second sentence of Section 11(d)(i) hereof) for the Trading Day
      immediately prior to the date of such exercise.
 
  (c) The holder of a Right by the acceptance of the Right expressly waives
      his right to receive any fractional Rights or any fractional shares
      upon exercise of a Right (except as provided above).
 
  Section 15. Rights of Action. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the
Right Certificates (and, prior to the Distribution Date, the registered
holders of the Exchangeable Shares); and any registered holder of any Right
Certificate (or, prior to the Distribution Date, of the Exchangeable Shares),
without the consent of the Rights Agent or of the holder of any other Right
Certificate (or, prior to the Distribution Date, of the Exchangeable Shares),
in his own behalf and for his own benefit, may enforce, and may institute and
maintain any suit, action or proceeding against the Company to enforce, and
may otherwise act in respect of, his right to exercise the Rights evidenced by
such Right Certificate in the manner provided in such Right Certificate and in
this Agreement. Without limiting the foregoing or any remedies available to
the holders of Rights, it is specifically acknowledged that the holders of
Rights would not have an adequate remedy at law for any breach of this
Agreement and will be entitled to specific performance of the obligations
under, and injunctive relief against actual or threatened violations of the
obligations of any Person subject to, this Agreement.
 
                                      14

 
  Section 16. Agreement of Right Holders. Every holder of a Right, by accepting
the same, consents and agrees with the Company and the Rights Agent and with
every other holder of a Right that:
 
  (a) prior to the Distribution Date, the Rights will be transferable only in
      connection with the transfer of the associated Exchangeable Shares;
 
  (b) after the Distribution Date, the Right Certificates are transferable
      only in the registry books of the Rights Agent if surrendered at the
      office or agency of the Rights Agent designated for such purpose, duly
      endorsed or accompanied by a proper instrument of transfer;
 
  (c) the Company and the Rights Agent may deem and treat the Person in whose
      name the Right Certificate (or, prior to the Distribution Date, the
      associated Exchangeable Shares certificate) is registered as the
      absolute owner thereof and of the Rights evidenced thereby
      (notwithstanding any notations of ownership or writing on the Right
      Certificates or the associated Exchangeable Shares certificate made by
      anyone other than the Company or the Rights Agent) for all purposes
      whatsoever, and neither the Company nor the Rights Agent shall be
      affected by any notice to the contrary; and
 
  (d) notwithstanding anything in this Agreement to the contrary, neither the
      Company nor the Rights Agent shall have any liability to any holder of
      a Right or to any other Person as a result of the Company's or the
      Rights Agent's inability to perform any of its obligations under this
      Agreement by reason of any preliminary or permanent injunction or other
      order, decree or ruling issued by a court of competent jurisdiction or
      by a government, regulatory or administrative agency or commission, or
      any statute, rule, regulation or executive order promulgated or enacted
      by any governmental authority, prohibiting or otherwise restraining
      performance of such obligation.
 
  Section 17. Right Certificate Holder Not Deemed a Stockholder. No holder, as
such, of any Right Certificate shall be entitled to vote, receive dividends or
be deemed for any purpose the holder of the Exchangeable Shares or any other
securities of the Company which may at any time be issuable on the exercise of
the Rights represented thereby, nor shall anything contained herein or in any
Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions thereof.
 
  Section 18. Concerning the Rights Agent.
 
  (a) The Company agrees to pay to the Rights Agent reasonable compensation
      for all services rendered by it hereunder and, from time to time, on
      demand of the Rights Agent, its reasonable expenses and counsel fees
      and other disbursements incurred in the administration and execution of
      this Agreement and the exercise and performance of its duties hereunder
      (including the reasonable fees and disbursements of any expert retained
      by the Rights Agent). The Company also agrees to indemnify the Rights
      Agent for, and to hold it harmless against any loss, liability or
      expense, incurred without negligence, bad faith or willful misconduct
      on the part of the Rights Agent, for anything done or omitted by the
      Rights Agent in connection with the acceptance and administration of
      this Agreement,
 
                                       15

 
     including legal costs and expenses, which right to indemnification will
     survive the termination of this Agreement or the resignation or removal
     of the Rights Agent.
 
  (b) The Rights Agent shall be protected and shall incur no liability for,
      in respect of any action taken, suffered or omitted by it in connection
      with, its administration of this Agreement in reliance upon any Right
      Certificate or certificate for the Exchangeable Shares or for other
      securities of the Company, instrument of assignment or transfer, power
      of attorney, endorsement, affidavit, letter, notice, direction,
      consent, certificate, statement, or other paper or document believed by
      it to be genuine and to be signed, executed and, where necessary,
      verified or acknowledged, by the proper Person or Persons, or otherwise
      upon the advice of counsel as set forth in Section 20 hereof.
 
  (c) The Company shall inform the Rights Agent in a reasonably timely manner
      of events which may materially affect the administration of this
      Agreement by the Rights Agent and, at any time upon request, shall
      provide to the Rights Agent an incumbency certificate certifying the
      then current officers of the Company.
 
  Section 19. Merger or Consolidation or Change of Name of Rights Agent.
 
  (a) Any corporation into which the Rights Agent or any successor Rights
      Agent may be merged or with which it may be consolidated, or any
      corporation resulting from any merger or consolidation to which the
      Rights Agent or any successor Rights Agent shall be a party, or any
      corporation succeeding to the stock transfer or corporate trust powers
      of the Rights Agent or any successor Rights Agent, shall be the
      successor to the Rights Agent under this Agreement without the
      execution or filing of any paper or any further act on the part of any
      of the parties hereto; provided, that such corporation would be
      eligible for appointment as a successor Rights Agent under the
      provisions of Section 21 hereof. In case at the time such successor
      Rights Agent shall succeed to the agency created by this Agreement, any
      of the Right Certificates shall have been countersigned but not
      delivered, any such successor Rights Agent may adopt the
      countersignature of the predecessor Rights Agent and deliver such Right
      Certificates so countersigned; and in case at that time any of the
      Right Certificates shall not have been countersigned, any successor
      Rights Agent may countersign such Right Certificates either in the name
      of the predecessor Rights Agent or in the name of the successor Rights
      Agent; and in all such cases such Right Certificates shall have the
      full force provided in the Right Certificates and in this Agreement.
 
  (b) In case at any time the name of the Rights Agent shall be changed and
      at such time any of the Right Certificates shall have been
      countersigned but not delivered, the Rights Agent may adopt the
      countersignature under its prior name and deliver Right Certificates so
      countersigned; and in case at that time any of the Right Certificates
      shall not have been countersigned, the Rights Agent may countersign
      such Right Certificates either in its prior name or in its changed
      name; and in all such cases such Right Certificates shall have the full
      force provided in the Right Certificates and in this Agreement.
 
  Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties
and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Right Certificates,
by their acceptance thereof, shall be bound:
 
  (a) The Rights Agent may retain and consult with legal counsel (who may be
      legal counsel for the Company), and the opinion of such counsel shall
      be full and complete authorization and protection to the Rights Agent
      as to any action taken or omitted by it in good faith and in
 
                                       16

 
     accordance with such opinion and the Rights Agent may also consult with
     such other experts as the Rights Agent shall consider necessary or
     appropriate, acting reasonably, to properly carry out its duties and
     obligations under this Agreement (at the expense of the Company) and the
     Rights Agent shall be entitled to act and rely in good faith on the
     advice of any such expert.
 
  (b) Whenever in the performance of its duties under this Agreement the
      Rights Agent shall deem it necessary or desirable that any fact or
      matter be proved or established by the Company prior to taking or
      suffering any action hereunder, such fact or matter (unless other
      evidence in respect thereof be herein specifically prescribed) may be
      deemed to be conclusively proved and established by a certificate
      signed by any of the Chairman of the Board of Directors, the President,
      any Vice President, the Treasurer, the Controller or the Secretary of
      the Company and delivered to the Rights Agent; and such certificate
      shall be full authorization to the Rights Agent for any action taken or
      suffered in good faith by it under the provisions of this Agreement in
      reliance upon such certificate.
 
  (c) The Rights Agent shall be liable hereunder to the Company and any other
      Person only for its own negligence, bad faith or willful misconduct.
 
  (d) The Rights Agent shall not be liable for or by reason of any of the
      statements of fact or recitals contained in this Agreement or in the
      Right Certificates or in the certificates for Common Shares or
      Exchangeable Shares (except its countersignature thereof) or be
      required to verify the same, but all such statements and recitals are
      and shall be deemed to have been made by the Company only.
 
  (e) The Rights Agent shall not be under any responsibility in respect of
      the validity of this Agreement or the execution and delivery hereof
      (except the due execution hereof by the Rights Agent) or in respect of
      the validity or execution of any Right Certificate; (except its
      countersignature thereof); nor shall it be responsible for any breach
      by the Company of any covenant or condition contained in this Agreement
      or in any Right Certificate; nor shall it be responsible for any change
      in the exercisability of the Rights (including the Rights becoming void
      pursuant to Section 11(a) (ii) hereof) or any adjustment in the terms
      of the Rights (including the manner, method or amount thereof) provided
      for in Sections 3, 11, 13, 23 and 24, or the ascertaining of the
      existence of facts that would require any such change or adjustment
      (except with respect to the exercise of Rights evidenced by Right
      Certificates after receipt of a certificate furnished pursuant to
      Section 12, describing such change or adjustment); nor shall it by any
      act hereunder be deemed to make any representation or warranty as to
      the authorization or reservation of any Exchangeable Shares to be
      issued pursuant to this Agreement or any Right Certificate or as to
      whether any Exchangeable Shares will, when issued, be validly
      authorized and issued, fully paid and nonassessable.
 
  (f) The Company agrees that it will perform, execute, acknowledge and
      deliver or cause to be performed, executed, acknowledged and delivered
      all such further and other acts, instruments and assurances as may
      reasonably be required by the Rights Agent for the carrying out or
      performing by the Rights Agent of the provisions of this Agreement.
 
  (g) The Rights Agent is hereby authorized and directed to accept written
      instructions with respect to the performance of its duties hereunder
      from any person reasonably believed by the Rights Agent to be one of
      the Chairman of the Board of Directors, the President, any Vice
      President, the Secretary, the Controller or the Treasurer of the
      Company, and to apply to such officers for advice or instructions in
      connection with its duties, and it shall not be
 
                                       17

 
     liable for any action taken or suffered by it in good faith in
     accordance with instructions of any such officer or for any delay in
     acting while waiting for those instructions. Any application by the
     Rights Agent for written instructions from the Company may, at the
     option of the Rights Agent, set forth in writing any action proposed to
     be taken or omitted by the Rights Agent under this Rights Agreement and
     the date on and/or after which such action shall be taken or such
     omission shall be effective. The Rights Agent shall not be liable for
     any action taken by, or omission of, the Rights Agent in accordance with
     a proposal included in any such application on or after the date
     specified in such application (which date shall not be less than five
     Business Days after the date any officer of the Company actually
     receives such application, unless any such officer shall have consented
     in writing to an earlier date) unless, prior to taking any such action
     (or the effective date in the case of an omission), the Rights Agent
     shall have received written instructions in response to such application
     specifying the action to be taken or omitted.
 
  (h) The Rights Agent and any stockholder, director, officer or employee of
      the Rights Agent may buy, sell or deal in any of the Rights or other
      securities of the Company or become pecuniarily interested in any
      transaction in which the Company may be interested, or contract with or
      lend money to the Company or otherwise act as fully and freely as
      though it were not Rights Agent under this Agreement. Nothing herein
      shall preclude the Rights Agent from acting in any other capacity for
      the Company or for any other legal entity.
 
 
  (i) The Rights Agent may execute and exercise any of the rights or powers
      hereby vested in it or perform any duty hereunder either itself or by
      or through its attorneys or agents, and the Rights Agent shall not be
      answerable or accountable for any act, default, neglect or misconduct
      of any such attorneys or agents or for any loss to the Company
      resulting from any such act, default, neglect or misconduct, provided
      reasonable care was exercised in the selection and continued employment
      thereof.
 
  Section 21. Change of Rights Agent. The Rights Agent or any successor Rights
Agent may resign and be discharged from its duties under this Agreement upon
30 days' notice in writing mailed to the Company and to each transfer agent of
the Exchangeable Shares by registered or certified mail, and to the holders of
the Right Certificates by first-class mail. The Company may remove the Rights
Agent or any successor Rights Agent upon 30 days' notice in writing, mailed to
the Rights Agent or successor Rights Agent, as the case may be, and to each
transfer agent of the Exchangeable Shares by registered or certified mail, and
to the holders of the Right Certificates by first-class mail. If the Rights
Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of 30 days after
giving notice of such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Right Certificate (who shall, within such notice, submit his
Right Certificate for inspection by the Company), then the resigning Rights
Agent or registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent at the
Company's expense. Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be a trust company organized and doing
business under the laws of Canada or any province of Canada, in good standing,
having an office in the Province of Ontario, which is authorized under the
laws of the Province of Ontario to exercise corporate trust or stock transfer
powers and is subject to supervision or examination by federal or provincial
authority and which has (together with its Affiliates) at the time of its
appointment as Rights Agent a combined capital and surplus of at least $50
million. After appointment, the successor Rights Agent shall be vested with
the same powers,
 
                                      18

 
rights, duties and responsibilities as if it had been originally named as
Rights Agent without further act or deed; but the predecessor Rights Agent
shall upon payment in full of any outstanding amounts owing by the Company to
the Rights Agent under this Agreement, deliver and transfer to the successor
Rights Agent any property at the time held by it hereunder, and execute and
deliver any further assurance, conveyance, act or deed necessary for the
purpose. Not later than the effective date of any such appointment the Company
shall file notice thereof in writing with the predecessor Rights Agent and each
transfer agent of the Exchangeable Shares, and mail a notice thereof in writing
to the registered holders of the Right Certificates. Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.
 
  Section 22. Issuance of New Right Certificates. Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary, the Company may,
at its option, issue new Right Certificates evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Agreement.
 
  Section 23. Redemption.
 
  (a) The Board of Directors of the Company shall, simultaneously with any
      order by the Board of Directors of Mattel pursuant to Section 24 of the
      Mattel Rights Agreement, order the redemption of all but not less than
      all the then outstanding Rights at a per Right redemption price equal
      to U.S. $.01 multiplied by the Merger Exchange Ratio appropriately
      adjusted to reflect any stock split, stock dividend or similar
      transaction occurring after the date hereof (such redemption price
      being hereinafter referred to as the "Redemption Price"). The
      redemption of the Rights shall be made effective at such time, on such
      basis and with such conditions as are imposed by the Board of Directors
      of Mattel in connection with the redemption of the Mattel Rights
      pursuant to Section 24 of the Mattel Rights Agreement.
 
  (b) Immediately upon the action of the Board of Directors ordering the
      redemption of the Rights pursuant to paragraph (a) of this Section 23
      (or at such later time as the Board of Directors may establish for the
      effectiveness of such redemption), and without any further action and
      without any notice, the right to exercise the Rights will terminate and
      the only right thereafter of the holders of Rights shall be to receive
      the Redemption Price. The Company shall promptly give public notice of
      any such redemption; provided, however, that the failure to give, or
      any defect in, any such notice shall not affect the validity of such
      redemption. Within 10 days after such action of the Board of Directors
      ordering the redemption of the Rights, the Company shall mail a notice
      of redemption to all the holders of the then outstanding Rights at
      their last addresses as they appear upon the registry books of the
      Rights Agent or, prior to the Distribution Date, on the registry books
      of the transfer agent for the Exchangeable Shares. Any notice which is
      mailed in the manner herein provided shall be deemed given, whether or
      not the holder receives the notice. Each such notice of redemption
      shall state the method by which the payment of the Redemption Price
      will be made. Neither the Company nor any of its Affiliates or
      Associates may redeem, acquire or purchase for value any Rights at any
      time except (i) in the manner specifically set forth in this Section 23
      or in Section 24 hereof or (ii) in connection with the purchase of
      Exchangeable Shares prior to the Distribution Date.
 
                                       19

 
  Section 24. Exchange.
 
  (a) Simultaneously with the action by the Board of Directors of Mattel to
      exercise its option to exchange the Mattel Rights pursuant to Section
      24 of the Mattel Rights Agreement, the then outstanding and exercisable
      Rights (which shall not include Rights that have become void pursuant
      to the provisions of Section 11 (a) (ii) hereof) shall be automatically
      and mandatorily exchanged in the same proportion and under the same
      terms and conditions as the Mattel Rights are exchanged pursuant to
      Section 24 of the Mattel Rights Agreement, for Exchangeable Shares at
      an exchange ratio of one Exchangeable Share per Right, appropriately
      adjusted to reflect any stock split, stock dividend or similar
      transaction occurring after the date hereof (such exchange ratio being
      hereinafter referred to as the "Exchange Ratio").
 
  (b) Immediately upon the exchange of any Rights pursuant to paragraph (a)
      of this Section 24 and without any further action and without notice,
      the right to exercise such Rights shall terminate and the only right
      thereafter of a holder of such Rights shall be to receive that number
      of Exchangeable Shares equal to the number of such Rights held by such
      holder multiplied by the Exchange Ratio. The Company shall promptly
      give public notice of any such exchange; provided, however, that the
      failure to give, or any defect in, such notice shall not affect the
      validity of such exchange. The Company promptly shall mail a notice of
      any such exchange to all of the holders of such Rights at their last
      addresses as they appear upon the registry books of the Rights Agent.
      Any notice which is mailed in the manner herein provided shall be
      deemed given, whether or not the holder receives the notice. Each such
      notice of exchange shall state the method by which the exchange of the
      Exchangeable Shares for Rights will be effected and, in the event of
      any partial exchange, the number of Rights which will be exchanged. Any
      partial exchange shall be effected pro rata based on the number of
      Rights (other than Rights which have become void pursuant to the
      provisions of Section 11(a)(ii) hereof) held by each holder of Rights.
 
  (c) In the event that there shall not be sufficient Exchangeable Shares
      issued but not outstanding or authorized but unissued to permit an
      exchange of Rights as contemplated in accordance with this Section 24,
      the Company shall take all such action as may be necessary to authorize
      additional Exchangeable Shares for issuance upon exchange of the
      Rights.
 
  (d) The Company shall not be required to issue fractions of Exchangeable
      Shares or to distribute certificates which evidence fractional
      Exchangeable Shares. In lieu of such fractional Exchangeable Shares,
      the Company shall pay to the registered holders of the Right
      Certificates with regard to which such fractional Exchangeable Shares
      would otherwise be issuable an amount in cash equal to the same
      fraction of the current market value of a whole Exchangeable Share. For
      the purposes of this paragraph (d), the current market value of a whole
      Exchangeable Share shall be the closing price of an Exchangeable Share
      (as determined pursuant to the second sentence of Section 11(d)(i)
      hereof) for the Trading Day immediately prior to the date of exchange
      pursuant to this Section 24.
 
  Section 25. Notice of Certain Events.
 
  (a) In case Mattel shall give notice to the holders of Mattel Rights
      pursuant to Section 25(a) of the Mattel Rights Agreement or in case the
      Company shall propose (i) to pay any dividend payable in stock of any
      class to the holders of its Exchangeable Shares or to make any other
      distribution to the holders of its Exchangeable Shares (other than a
      regular quarterly cash dividend), (ii) to offer to the holders of its
      Exchangeable Shares rights or warrants to
 
                                       20

 
     subscribe for or to purchase any additional Exchangeable Shares or
     shares of stock of any class or any other securities, rights or options,
     (iii) to effect any reclassification of its Exchangeable Shares (other
     than a reclassification involving only the subdivision of outstanding
     Exchangeable Shares), (iv) to effect any consolidation or merger into or
     with, or to effect any sale or other transfer (or to permit one or more
     of its Subsidiaries to effect any sale or other transfer), in one or
     more transactions, of 50% or more of the assets or earning power of the
     Company and its Subsidiaries (taken as a whole) to, any other Person,
     (v) to effect the liquidation, dissolution or winding up of the Company,
     or (vi) to declare or pay any dividend on the Exchangeable Shares
     payable in Exchangeable Shares or to effect a subdivision, combination
     or consolidation of the Exchangeable Shares (by reclassification or
     otherwise than by payment of dividends in Exchangeable Shares), then, in
     each such case, Mattel or the Company, as the case may be, shall give to
     each holder of a Right Certificate, in accordance with Section 26
     hereof, a notice of such proposed action, which shall specify the record
     date for the purposes of such stock dividend, or distribution of rights
     or warrants, or the date on which such reclassification, consolidation,
     merger, sale, transfer, liquidation, dissolution or winding up is to

  This certifies that      , or registered assigns, is the registered owner of
the number of Rights set forth above, each of which entitles the owner

Agreement, dated as of May 13, 1999 (the "Rights Agreement"), between Softkey
Software Products Inc., an Ontario Corporation (the "Company"), Mattel Inc., a
Delaware corporation ("Mattel"), and CIBC Mellon Trust Company, a trust

term is defined in the Rights Agreement) and prior to 5:00 P.M., New York City
time, on February 17, 2002 at the office or agency of the Rights Agent
designated for such purpose, or of its successor as Rights Agent, one fully
paid non-assessable exchangeable share in the capital stock of the Company
(the "Exchangeable Shares"), at a purchase price per Exchangeable Share equal
to U.S. $150 multiplied by the Merger Exchange Ratio (the "Purchase Price"),
upon presentation and surrender of this Right Certificate with the form of
Election to Purchase duly executed. The number of Rights evidenced by this
Right Certificate (and the number of Exchangeable Shares which may be
purchased upon exercise hereof) set forth above, and the Purchase Price set
forth above, are the number and Purchase Price as of May 13, 1999, based on
the Exchangeable Shares as constituted at such date. As provided in the Rights
Agreement, the Purchase Price and the number of Exchangeable Shares which may
be purchased upon the exercise of the Rights evidenced by this Right
Certificate are subject to modification and adjustment upon the happening of
certain events.
 
  This Right Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the

  This Right Certificate, with or without other Right Certificates, upon
surrender at the office or agency of the Rights Agent designated for such
purpose, may be exchanged for another Right Certificate or Right Certificates
of like tenor and date evidencing Rights entitling the holder to purchase a
like aggregate number of Exchangeable Shares as the Rights evidenced by the
Right Certificate or Right Certificates surrendered shall have entitled such
holder to purchase. If this Right
 
                                      A-1

 
Certificate shall be exercised in part, the holder shall be entitled to receive
upon surrender hereof another Right Certificate or Right Certificates for the
number of whole Rights not exercised.
 
  Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Right Certificate (i) may be redeemed by the Company at a redemption price
per Right equal to U.S. $.01 multiplied by the Merger Exchange Ratio or (ii)
may be exchanged by the Company in whole or in part for Exchangeable Shares.
 
  No fractional Exchangeable Shares will be issued upon the exercise or
exchange of any Right or Rights evidenced hereby, but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement.
 
  No holder of this Right Certificate, as such, shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of the Exchangeable
Shares or of any other securities of the Company which may at any time be

Agreement or herein be construed to confer upon the holder hereof, as such, any

matter submitted to stockholders of the Company or Mattel at any meeting
thereof, or to give or withhold consent to any corporate action, or to receive
notice of meetings or other actions affecting stockholders (except as provided

                         SOFTKEY SOFTWARE PRODUCTS INC.
 
                         SUMMARY OF RIGHTS TO PURCHASE
                              EXCHANGEABLE SHARES
 
  On May 7, 1999, the Board of Directors of Softkey Software Products Inc. (the
"Company") authorized the issuance of one exchangeable share purchase right (a
"Right") for each outstanding exchangeable share (the "Exchangeable Shares") of
the Company. Rights were issued on May 13, 1999 (the "Record Date") to the
stockholders of record on that date. Each Right entitles the registered holder
to purchase from the Company one Exchangeable Share of the Company at a price
per Exchangeable Share equal to U.S. $150 multiplied by 1.2 (which is the
Merger Exchange Ratio, as defined in the Rights Agreement) (the "Purchase
Price"), subject to adjustment. The description and terms of the Rights are set
forth in a Rights Agreement dated as of May 13, 1999 (the "Rights Agreement")
between the Company, Mattel, Inc. ("Mattel") and CIBC Mellon Trust Company, as
Rights Agent (the "Rights Agent").
 
  Until the earlier to occur of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") have acquired beneficial ownership of 20% or more of the aggregate
number of the shares of common stock, par value U.S. $1.00 per share of Mattel
(the "Mattel Common Shares") and Exchangeable Shares then outstanding or (ii)
10 business days (or such later date as may be determined by action of the
Board of Directors of Mattel prior to such time as any person or group of
affiliated persons becomes an Acquiring Person) following the commencement of,
or announcement of an intention to make, a tender offer or exchange offer the
consummation of which would result in the beneficial ownership by a person or
group of 20% or more of the aggregate number of Mattel Common Shares and
Exchangeable Shares then outstanding (the earlier of such dates being called
the "Distribution Date"), the Rights will be evidenced, with respect to any of
the Exchangeable Share certificates outstanding as of the Record Date, by such
Exchangeable Share certificates with a copy of this Summary of Rights. For
purposes of the foregoing, the number of Exchangeable Shares outstanding will
mean 1.2 multiplied by the number of Exchangeable Shares then issued and
outstanding which are not owned by Mattel, any of its subsidiaries or any
person controlled by Mattel.
 
  The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights), the Rights will be transferred with
and only with the Exchangeable Shares. Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Exchangeable Share certificates
issued after the Record Date upon transfer or new issuance of Exchangeable
Shares will contain a notation incorporating the Rights Agreement by reference.
Until the Distribution Date (or earlier redemption or expiration of the
Rights), the surrender for transfer of any certificates for Exchangeable Shares
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights being attached thereto, will also constitute the transfer of
the Rights associated with the Exchangeable Shares represented by such
certificates. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Exchangeable Shares as of the close of business on the
Distribution Date and such separate Right Certificates alone will evidence the
Rights.
 
  The rights are not exercisable until the Distribution Date. The Rights will
expire on February 17, 2002 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company, in each case as described below.
 
                                      B-1

 
  The Purchase Price payable, and the number of Exchangeable Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the
Exchangeable Shares, (ii) upon the grant to holders of the Exchangeable Shares
of certain rights or warrants to subscribe for or purchase Exchangeable Shares
at a price, or securities convertible into Exchangeable Shares with a
conversion price, less than the then-current market price of the Exchangeable
Shares or (iii) upon the distribution to holders of the Exchangeable shares of
evidences of indebtedness or assets (excluding regular periodic cash dividends
paid out of earnings or retained earnings or dividends in Exchangeable Shares)
or of subscription rights or warrants (other than those referred to above).
 
  In the event that, after a person or group has become an Acquiring Person,
Mattel is acquired in a merger or other business combination transaction or 50%
or more of Mattel's consolidated assets or earnings power are sold, proper
provision will be made so that each holder of a Right will thereafter have the
right to receive, upon the exercise thereof at the then current exercise price
of the Right, that number of shares of common stock of the acquiring company
which at the time of such transaction will have a market value of two times the
exercise price of the Right. In the event that any person or group of
affiliated or associated persons becomes an Acquiring Person, proper provision
shall be made so that each holder of a Right, other than Rights beneficially
owned by the Acquiring Person (which will thereafter be void), will thereafter
have the right to receive upon exercise that number of Exchangeable Shares
having a market value of two times the exercise price of the Right.
 
  At any time after any person or group becomes an Acquiring Person and prior
to the acquisition by such person or group of 50% or more of the Mattel Common
Shares and Exchangeable Shares outstanding, the Board of Directors of Mattel
may take certain actions which, if taken, will result in the automatic and
mandatory exchange of the Rights (other than Rights owned by such person or
group which will have become void), in whole or in part, at an exchange ratio
of one Exchangeable Share per Right (subject to adjustment).
 
  With certain exceptions, no adjustment in the Purchase Price will be required
until cumulative adjustments require an adjustment of at least 1% in such
Purchase Price. No fractional Exchangeable Shares will be issued and in lieu
thereof, an adjustment in cash will be made based on the market price of the
Exchangeable Shares on the last trading day prior to the date of exercise.
 
  At any time prior to the time an Acquiring Person becomes such, the Board of
Directors of the Company shall, simultaneously with any order by the Mattel
Board of Directors to redeem the Mattel Rights, order the redemption of the
Rights in whole, but not in part, at a price per Right equal to U.S. $.01
multiplied by 1.2 (the "Redemption Price"). The redemption of the Rights shall
be made effective at such time, on such basis and with such conditions as are
imposed by the Board of Directors of Mattel in connection with the redemption
of the Mattel Rights. Immediately upon any redemption of the Rights, the right
to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price.
 
  The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights except that from and
after such time as any person or group of affiliated or associated persons
becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights. If any provision of the Mattel Rights
Agreement (as defined in the Rights Agreement) is supplemented or amended, the
Company is required to
 
                                      B-2

 
supplement or amend the Rights Agreement in substantially the same manner, and
the Rights Agreement generally is not otherwise permitted to be supplemented or
amended.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a holder of Exchangeable Shares or Mattel Common Shares, including, without
limitation, the right to vote or to receive dividends.
 
  A copy of the Rights Agreement is available free of charge from the Company.
This summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement, which is hereby
incorporated herein by reference.
