securities of such corporation except to the extent that such ownership existed
prior to the Business Combination and (C) at least a majority of the members of
the board of directors of the corporation resulting from such Business
Combination were members of the Incumbent Board at the time of the execution of
the initial agreement, or of the action of the Board, providing for such
Business Combination; or

         (iv) Approval by the shareholders of the Company of a complete
liquidation or dissolution of the Company.

20.  Cancellation of Grants.   Except as otherwise provided in the Grant, the
     ----------------------
Committee may cancel any unexpired, unpaid, or deferred Grant at any time if the
Participant does not comply with all of the terms of the Grant and the following
conditions.

     (a) A Participant shall not render services for any organization or engage
directly or indirectly in any business that, in the judgment of the Chief
Executive Officer of the Company or other senior officer designated by the
Committee, is or becomes competitive with the Company, or which organization or
business, or the rendering of services to such organization or business, is or
becomes otherwise prejudicial to or in conflict with the interests of the
Company. For Participants whose employment has terminated, the judgment of the
Chief Executive Officer shall be based on the Participant's position and
responsibilities while employed by the Company, the Participant's
post-employment responsibilities and position with the other organization or
business, the extent of past, current and potential competition or conflict
between the Company and the other organization or business, the effect on the
Company's customers, suppliers and competitors of the Participant assuming the
post-employment position and such other considerations as are deemed relevant
given the applicable facts and circumstances. A Participant who has retired
shall be free, however, to purchase as an investment or otherwise, stock or
other securities of such organization or business so long as they are listed
upon a recognized securities exchange or traded over-the-counter, and such
investment does not represent a substantial investment to the Participant or a
greater than five percent (5%) equity interest in the organization or business.

     (b) A Participant shall not, without prior written authorization from the
Company, disclose to anyone outside the Company, or use in other than the
Company's business, any confidential information or material, as those terms are
used in the Company's Employee Patent and Confidence Agreement, relating to the
business of the Company, acquired by the Participant either during or after
employment with the Company.

                                       11
<PAGE>

     (c) A Participant, pursuant to the Company's Employee Patent and Confidence
Agreement, shall disclose promptly and assign to the Company all right, title,
and interest in any invention or idea, patentable or not, made or conceived by
the Participant during employment by the Company, relating in any manner to the
actual or anticipated business, research, or development work of the Company and
shall do anything reasonably necessary to enable the Company to secure a patent
where appropriate in the United States and in foreign countries.

     (d) Upon exercise, payment, or delivery pursuant to an Award, the
Participant shall certify on a form acceptable to the Committee that he or she
is in compliance with the terms and conditions of the Plan. Failure to comply
with the provisions of paragraph (a), (b) or (c) of this Section 20 prior to, or
during the six (6) months after, any exercise, payment or delivery pursuant to
an Award may, at the Committee's discretion, cause such exercise, payment or
delivery to be rescinded. The Company shall notify the Participant in writing of
any such rescission within two (2) years after such exercise, payment or
delivery. Within ten (10) days after receiving such a notice from the Company,
the Participant shall pay to the Company the amount of any gain realized or
payment received as a result of the rescinded exercise, payment, or delivery
pursuant to an Award. Such payment shall be made either in cash or by returning
to the Company the number of shares of Common Stock that the Participant
received in connection with the rescinded exercise, payment, or delivery.

21.  [Intentionally Omitted.]

22.  Amendments and Termination.  The Board may at any time amend or terminate
     --------------------------
this Plan.  However, no amendment or termination of the Plan may impair the
rights of a Participant holding a Grant without his or her consent.

23.  Tax Withholding.
     ---------------

     (a) The Company shall have the right to take such actions as may be
necessary to satisfy its tax withholding obligations relating to the operation
of this Plan.

     (b) If Common Stock is used to satisfy the Company's tax withholding
obligations, the stock shall be valued at its Fair Market Value when the tax
withholding is required to be made.

     (c) Notwithstanding any other provision of this Plan, the number of shares
of Common Stock otherwise issuable upon the exercise of an Option which may be
withheld in order to satisfy the Participant's federal and state income and
payroll tax liabilities with respect to the exercise or vesting of the Option
shall be limited to the number of shares which have a Fair Market Value equal to
the aggregate amount of such liabilities based on the minimum statutory
withholding rates for federal and state income tax and payroll tax purposes that
are applicable to such supplemental taxable income.

24.  No Additional Rights.
     --------------------

     (a) Neither the adoption of this Plan nor the granting of any Option or
Restricted Stock shall:

                                       12
<PAGE>

         (i)  Affect or restrict in any way the power of the Company to
undertake any corporate action otherwise permitted under applicable law; or

         (ii) Confer upon any Participant the right to continue performing
services for the Company, nor shall it interfere in any way with the right of
the Company to terminate the services of any Participant at any time, with or
without cause.

     (b) No Participant shall have any rights as a stockholder with respect to
any shares covered by a Grant until the date a certificate for such shares has
been issued to the Participant following the exercise of an Option or the
receipt of Restricted Stock.

25.  Securities Law Restrictions.
     ---------------------------

     (a) No securities shall be issued under this Plan unless the Committee
shall be satisfied that the issuance will be in compliance with applicable
federal and state securities laws.

     (b) The Committee may require certain investment (or other) representations
and undertakings in connection with the issuance of securities in connection
with the Plan in order to comply with applicable law.

     (c) Certificates for shares of Common Stock delivered under this Plan may
be subject to such restrictions as the Committee may deem advisable. The
Committee may cause a legend to be placed on the certificates to refer to those
restrictions.

26.  Indemnification.   To the maximum extent permitted by law, the Company
     ---------------
shall indemnify each member of the Committee and of the Board, as well as any
other Employee of the Company with duties under this Plan, against expenses
(including any amount paid in settlement) reasonably incurred by the individual
in connection with any claims against the individual by reason of the
performance of the individual's duties under this Plan, unless the losses are
due to the individual's gross negligence or lack of good faith.  The Company
will have the right to select counsel and to control the prosecution or defense
of the suit.  The Company will not be required to indemnify any person for any
amount incurred through any settlement unless the Company consents in writing to
the settlement.

27.  Governing Law.   This Plan and all actions taken hereunder shall be
     -------------
governed by and construed in accordance with the laws of the State of Delaware.

                             Grant Agreement for a
                          Non-Qualified Stock Option
                    under the Mattel 1999 Stock Option Plan

     This is an Option Agreement between Mattel, Inc. (the "Company") and the
individual (the "Option Holder") named in the Notice of Grant of Stock Option
(the "Notice) attached hereto as the cover page of this agreement.

Recitals

     The Company has adopted the Mattel 1999 Stock Option Plan (the "Plan") for
the granting to selected employees of options to purchase shares of Common Stock
of the Company.  In accordance with the terms of the Plan, the
Compensation/Options Committee of the Board of Directors (the "Committee"), has
approved the execution of this Grant Agreement (the "Option") between the
Company and the Option Holder.  Capitalized terms used herein without definition
shall have the meanings assigned to such terms in the Plan.

Option

     1.  Terms.    The Company grants to the Option Holder the right and option
         -----
to purchase on the terms and conditions hereinafter set forth, all or any part
of the aggregate number of shares set forth in the Notice of Common Stock
exercisable in accordance with the provisions of this Option during a period
expiring ten years from the date of the Notice (the "Expiration Date"), unless
terminated prior to that date pursuant to Section 5 or 6 below.  This Option is
a Non-Qualified Stock Option.

     2.  Exercisability (Vesting).    The Option Holder may purchase the

==============================================================================================
</TABLE>
<PAGE>

     The number of shares that may be purchased upon exercise of this Option
shall in each case be calculated to the nearest full share.

     3.  Method of Exercising.    Each exercise of this Option shall be by means
         --------------------
of a written notice of exercise delivered to the office of the Secretary of the
Company, specifying the number of whole shares to be purchased, accompanied by
payment of the full purchase price of the shares to be purchased.  The payment
shall be in the form of cash or such other forms of consideration as the
Committee shall deem acceptable, such as the surrender of outstanding shares of
Common Stock owned by the Option Holder or by withholding shares that would
otherwise be issued upon the exercise of the Option.  The Option Holder may
exercise this Option by the delivery to the Company or its designated agent of
an irrevocable written notice of exercise form together with irrevocable
instructions to the broker-dealer to sell or margin a sufficient portion of the
shares of Common Stock and to deliver the sale or margin loan proceeds directly
to the Company to pay the exercise price of this Option.

     4.  Withholding.    Upon exercise, the Option Holder shall pay, or make
         -----------
provisions satisfactory to the Company or its Subsidiary for payment of any
federal, state and local taxes required to be withheld.

     5.  Cancellation of Grants.    Option Holder specifically acknowledges that
         ----------------------
this Option is subject to the provisions of Section 20 of the plan, entitled
"Cancellation of Grants," which can cause the forfeiture of this Option, or the
rescission of Common Stock acquired upon the exercise of this Option.  As a
condition of the exercise of this Option, the Option Holder shall certify on a
form acceptable to the Committee that he or she is in compliance with the terms
and conditions of the plan, including Section 20 thereof, entitled "Cancellation
of Grants."

     6.  Term.    Any portion of this Option that is not exercisable pursuant to
         ----
Section 2 on the date upon which the Option Holder's employment with the Company
and its Subsidiaries terminates shall terminate immediately upon the termination
of the Option Holder's employment with the Company and its Subsidiaries.  Any
portion of this Option that is exercisable on the date upon which the Option
Holder's employment with the Company and its Subsidiaries terminates shall
terminate ninety (90) days after the Option Holder ceases to be an employee of
the Company or one of its Subsidiaries for any reason other than as described
below.

         i.    If the Option Holder's employment is terminated by reason of
     death, the heirs of the Option Holder will be able to exercise this Option
     until the earlier of (a) one (1) year following the death of the Optionee
     or (b) the date on which this Option would otherwise expire.

                                       2
<PAGE>

         ii.   If the Option Holder's employment is terminated after the
     attainment of age fifty-five (55) and the completion of five (5) years of
     service (as determined in accordance with the terms of the Mattel, Inc.
     Personal Investment Plan), the Option Holder will be able to exercise this
     Option until the earlier of (a) five (5) years following termination of
     employment or (b) the date on which this Option would otherwise expire.

     7.  Compliance with Law.    No shares issuable upon the exercise of this
         -------------------
Option shall be issued and delivered unless and until all applicable
registration requirements of the Securities Act of 1933, all applicable listing
requirements of any national securities exchange on which the Common Stock is
then listed, and all other requirements of law or of any regulatory bodies
having jurisdiction over such issuance and delivery, shall have been complied
with.  In particular, the Committee may require certain investment (or other)
representations and undertakings in connection with the issuance of securities
in connection with the Plan in order to comply with applicable law.

     8.  Assignability.    Except as may be effected by will or by the laws of
         -------------
descent and distribution, any attempt to assign this Option shall be of no
effect.

     9.  Certain Corporate Transactions.    In the event of any change in the
         ------------------------------
Common Stock by reason of a stock split, stock dividend, combination or
reclassification of shares, recapitalization, merger, or similar event the
Committee may adjust proportionately the number of shares and the stock price of
the Common Stock subject to this Option.  In the event of any other change
affecting the Common Stock or any distribution (other than normal cash
dividends) to holders of Common Stock, the Committee may make such adjustments
as it may deem equitable (including adjustments to avoid fractional shares) in
order to give proper effect to such event.  In the event of a corporate merger,
consolidation, acquisition of property or stock, spin-off, reorganization or
liquidation, the Committee may substitute a new option for this Option or
provide for the assumption of this Option by the other corporation that is a
party to the transaction.

     10.   No Additional Rights.    Neither the granting of this Option nor its
           --------------------
exercise shall (a) confer upon the Option Holder any right to continue in the
employ of the Company (b) interfere in any way with the rights of the Company or
a Subsidiary to terminate such employment at any time for any reason, with or
without cause, or (c) interfere with the right of the Company or a Subsidiary to
undertake any lawful corporate action.  Option Holder acknowledges that he or
she is an "employee at will."  The provisions of this Section 10 are subject to
the terms of any employment agreement between the Option Holder and the Company
(or a Subsidiary).

     11.  Rights as a Stockholder.    Neither the Option Holder nor any other
          -----------------------
person legally entitled to exercise this Option shall be entitled to any of the
rights or privileges of a stockholder of the Company in respect of any shares
issuable upon any

                                       3
<PAGE>

exercises of this Option unless and until a certificate or certificates
representing such shares shall have been actually issued and delivered to the
Option Holder.

     12.  Compliance with Plan.    This Option is subject to, and the Company
          --------------------
and Option Holder agree to be bound by, all of the terms and conditions of the
Plan as it shall be amended from time-to-time.  No amendment to the plan shall
adversely affect this Option without the consent of the Option Holder.  In the
case of a conflict between the terms of the Plan and this Option, the terms of
the Plan shall govern.

     13.  Governing Law.    This Option has been granted, executed and delivered
          -------------
with effect from the date of Notice, at El Segundo, California, and
interpretation, performance and enforcement of this Option shall be governed by
the laws of the State of Delaware.
