          THIS AGREEMENT (the “Option Agreement”) is made and entered into as of
                                        , 2004 (the “Date of Grant”), by and
between Zilog, Inc., a Delaware corporation (the “Company”), and
[                                        ] (the “Optionee”). Capitalized terms
not defined herein shall have the meaning given to them in the Company’s 2004
Omnibus Stock Incentive Plan (the “Plan”). Where the context permits, references
to the Company or any of its Subsidiaries or affiliates shall include the
successors to the foregoing.
          Pursuant to the Plan, the Administrator has determined that the
Optionee is to be granted an option (the “Option”) to purchase Shares, subject
to the terms and conditions set forth in the Plan and herein, and hereby grants
such Option.
          This Option is intended to be a nonqualified stock option. The
prospectus for the Plan describes the differences between a nonqualified stock
option and an incentive stock option.
          1. Number of Shares and Exercise Price. The Option entitles the
Optionee to purchase [                    ] Shares (the “Option Shares”) at a
price of $[                    ] per share (the “Option Exercise Price”).
          2. Option Term. The term of the Option and of the Option Agreement
(the “Option Term”) shall commence on the Date of Grant and, unless the Option
is previously terminated pursuant to Paragraph 5 below, shall terminate upon the
expiration of ten (10) years from the Date of Grant (the “Expiration Date”). As
of the Expiration Date, all rights of the Optionee hereunder shall terminate.
          3. Conditions of Exercise.

  (a)   Subject to Paragraph 5 below, the Option shall become vested and
exercisable as to                                         , provided that the
Optionee has been continuously employed by or providing services to the Company
or any Subsidiary or affiliate through each such date.     (b)   Except as
otherwise provided herein, the right of the Optionee to purchase Option Shares
with respect to which the Option has become exercisable and vested may be
exercised in whole or in part at any time or from time to time prior to the
Expiration Date; provided, however, that the Option may not be exercised for a
fraction of a Share.

          4. Method of Exercise. This Option may be exercised, in whole or in
part, by means of a written notice of exercise to the Company in the form
attached hereto as Exhibit A, or in such other form as may be approved by the
Administrator from time to time, accompanied by payment in full of the aggregate
Option Exercise Price which may be made (i) in cash or by check, (ii) to the
extent permitted by applicable law, by means of any cashless exercise or same
day sale procedure approved by the Administrator, (iii) in the form of
unrestricted Shares already owned by the Optionee for at least six months on the
date of surrender to the extent the unrestricted Shares have a Fair Market Value
on

the date of surrender equal to the aggregate Option Exercise Price of the Shares
as to which such Option shall be exercised, or (iv) any combination of the
foregoing.
          5. Termination of Employment or Service; Change in Control.

  (a)   If the Optionee’s employment with or service to the Company, or any
Subsidiary or affiliate thereof, terminates for any reason other than for Cause,
the Option, to the extent vested and exercisable as of the date of such
termination, shall expire 90 days following the date of such termination
(180 days in case of termination of employment or service due to death or
Disability) and the Option, to the extent not vested and exercisable as of the
date of such termination, shall expire as of such date. Notwithstanding the
foregoing, if the Optionee’s employment with or service to the Company, any
Subsidiary or affiliate thereof terminates for Cause, the Option, whether or not
vested or exercisable, shall expire as of the date of such termination. In no
event shall the Option be exercisable after the Expiration Date.     (b)   Upon
the occurrence of a Change in Control, any portion of the Option that is
outstanding at such time shall become fully and immediately vested and
exercisable.

          6. Adjustments. The Option and all rights and obligations under this
Option Agreement are subject to Section 5 of the Plan.
          7. Nontransferability of Option. Except by will or under the laws of
descent and distribution and as set forth in the following two sentences, the
Optionee may not sell, transfer, pledge or assign the Option, and, during the
lifetime of the Optionee, only the Optionee may exercise the Option.
Notwithstanding the foregoing, during the Optionee’s lifetime, the Administrator
may, in its sole discretion, permit the transfer, assignment or other
encumbrance of the Option. Additionally, subject to the approval of the
Administrator and to any conditions that the Administrator may prescribe, the
Optionee may, upon providing written notice to the Company, elect to transfer
the Option (i) to members of his or her Immediate Family, provided that no such
transfer may be made in exchange for consideration, (ii) by instrument to an
inter vivos or testamentary trust in which the Option is to be passed to
beneficiaries upon the death of the Optionee, or (iii) pursuant to a qualified
domestic relations order within the meaning of Section 414(p) of the Code or any
similar instrument, to the extent permitted by applicable law. Any attempted
sale, transfer, pledge, assignment, encumbrance or other disposition of the
Option contrary to the provisions hereof shall be null and void and without
effect.
          8. Notice. Whenever any notice is required or permitted hereunder,
such notice shall be in writing and shall be given by personal delivery,
facsimile, first class mail, certified or registered with return receipt
requested. Any notice required or permitted to be delivered hereunder shall be
deemed to have been duly given on the date which it is personally delivered or,
whether actually received or not, on the third business

require the Optionee to remit to the Company (or Subsidiary or affiliate, as the
case may be) in cash an amount sufficient to satisfy any federal, state and
local tax withholding requirements related to the exercise of the Option. With
the approval of the Administrator, the Optionee may satisfy the foregoing
requirement by electing to have the Company withhold from delivery Shares or by
delivering Shares, in each case, having a value equal to the aggregate required
minimum tax withholding to be collected by the Company or any Subsidiary or
affiliate thereof. Such Shares shall be valued at their Fair Market Value on the
date on which the amount of tax to be withheld is determined. Fractional share
amounts shall be settled in cash.
          10. Compliance with Laws.
          (a) Shares shall not be issued pursuant to the exercise of the Option
granted hereunder unless the exercise of such Option and the issuance and
delivery of such Shares pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act, the Sarbanes-Oxley Act of 2002 and the requirements
of any stock exchange upon which the Shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance. The Company shall be under no obligation to effect the registration
pursuant to the Securities Act of 1933, as amended, of any interests in the Plan
or any Shares to be issued hereunder or to effect similar compliance under any
state laws.
          (b) All certificates for Shares delivered under the Plan shall be

Administrator may deem advisable under the rules, regulations, and other
requirements of the Securities and Exchange

--------------------------------------------------------------------------------

 

Commission, any stock exchange upon which the Shares may then be listed, and any
applicable federal or state securities law, and the Administrator may cause a
legend or legends to be placed on any such certificates to make appropriate
reference to such restrictions. The Administrator may require, as a condition of
the issuance and delivery of certificates evidencing Shares pursuant to the
terms hereof, that the recipient of such Shares make such agreements and
representations as the Administrator, in its sole discretion, deems necessary or
desirable.
          11. Protections Against Violations of Agreement. No purported sale,
assignment, mortgage, hypothecation, transfer, pledge, encumbrance, gift,
transfer in trust (voting or other) or other disposition of, or creation of a
security interest in or lien on, any of the Option Shares by any holder thereof
in violation of the provisions of this Option Agreement or the Articles of
Incorporation or the Bylaws of the Company, will be valid, and the Company will
not transfer any of such Option Shares on its books nor will any of such Option
Shares be entitled to vote, nor will any dividends be paid thereon, unless and
until there has been full compliance with such provisions to the satisfaction of
the Company. The foregoing restrictions are in addition to and not in lieu of
any other remedies, legal or equitable, available to enforce said provisions.
          12. Failure to Enforce Not a Waiver. The failure of the Company to
enforce at any time any provision of the Option Agreement shall in no way be
construed to be a waiver of such provision or of any other provision hereof.
          13. Governing Law. The Option Agreement shall be governed by and
construed according to the laws of the State of Delaware without regard to its
principles of conflict of laws.
          14. Incorporation of the Plan. The Plan, as it exists on the date of
the Option Agreement and as amended from time to time, is hereby incorporated by
reference and made a part hereof, and the Option and this Option Agreement shall
be subject to all terms and conditions of the Plan. In the event of any conflict
between the provisions of the Option Agreement and the provisions of the Plan,
the terms of the Plan shall control, except as expressly stated otherwise. The
term “Section” generally refers to provisions within the Plan; provided,
however, the term “Paragraph” shall refer to a provision of this Option
Agreement.
          15. Amendments. This Option Agreement may be amended or modified at
any time by an instrument in writing signed by each of the parties hereto;
provided, however, that any amendment or modification that does not impair the
rights of the Optionee may be effectuated by the Administrator without the
consent of the Optionee.
          16. Rights as a Shareholder. Neither the Optionee nor any of the
Optionee’s successors in interest shall have any rights as a shareholder of the
Company with respect to any Option Shares until the Optionee has given written
notice of exercise, has paid in full for such Shares, and has satisfied the
requirements in Sections 12, 13(b) and 13(c) of the Plan.

--------------------------------------------------------------------------------

 

          17. Agreement Not a Contract of Employment. Neither the Plan, the
granting of the Option, the Option Agreement nor any other action taken pursuant
to the Plan shall constitute or be evidence of any agreement or understanding,
express or implied, that the Optionee has a right to continue to be employed by,
or to provide services as a director, consultant or advisor to, the Company, any
Subsidiary or affiliate thereof for any period of time or at any specific rate
of compensation.
          18. Authority of the Administrator. The Administrator shall have full
authority to interpret and construe the terms of the Plan and the Option
Agreement. The determination of the Administrator as to any such matter of
interpretation or construction shall be final, binding and conclusive.
          19. Binding Effect. The Option Agreement shall apply to and bind the
Optionee and the Company and their respective permitted assignees or
transferees, heirs, legatees, executors, administrators and legal successors.
          20. Tax Representation. The Optionee has reviewed with his or her own
tax advisors the Federal, state, local and foreign tax consequences of the
transactions contemplated by this Option Agreement. The Optionee is relying
solely on such advisors and not on any statement or representations of the
Company or any of its agents. The Optionee understands that he or she (and not
the Company) shall be responsible for any tax liability that may arise as a
result of the transactions contemplated by the Option Agreement.
          21. Acceptance. The Optionee hereby acknowledges receipt of a copy of
the Plan and this Option Agreement. Optionee has read and understands the terms
and provisions thereof, and accepts the Option subject to all the terms and
conditions of the Plan and the Option Agreement.
