purchaser of such Shares did not receive any benefits of ownership of such
Shares, such Shares shall become available for future grant under the Plan.
For purposes of the preceding sentence, voting rights shall not be considered a
benefit of Share ownership.

       4.     Administration of the Plan.

              (a)    Procedure.

                     (i)     Multiple Administrative Bodies.  If permitted by
Rule 16b-3, the Plan may be administered by different bodies with respect to

Purchase Right grants made to Employees who are also Officers subject to
Section 16(b) of the Exchange Act, the Plan shall be administered by (A) the

rules under Rule 16b-3 relating to the disinterested administration of employee
benefit plans under which Section 16(b) exempt discretionary grants and awards

                                      -4-
<PAGE>   5
to be made, or (B) a committee designated by the Board to administer the Plan,
which committee shall be constituted to comply with the rules under Rule 16b-3
relating to the disinterested administration of employee benefit plans under
which Section 16(b) exempt discretionary grants and awards of equity securities
are to be made.  Once appointed, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board.  From time to time
the Board may increase the size of the Committee and appoint additional
members, remove members (with or without cause) and substitute new members,
fill vacancies (however caused), and remove all members of the Committee and
thereafter directly administer the Plan, all to the extent permitted by the
rules under Rule 16b-3 relating to the disinterested administration of employee
benefit plans under which Section 16(b) exempt discretionary grants and awards
of equity securities are to be made.

                     (iii)   Administration With Respect to Other Persons.
With respect to Option or Stock Purchase Right grants made to Employees or
Consultants who are not Officers of the Company, the Plan shall be administered
by (A) the Board or (B) a committee designated by the Board, which committee
shall be constituted to satisfy Applicable Laws.  Once appointed, such
Committee shall serve in its designated capacity until otherwise directed by
the Board.  The Board may increase the size of the Committee and appoint
additional members, remove members (with or without cause) and substitute new
members, fill vacancies (however caused), and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by Applicable Laws.

              (b)    Powers of the Administrator.  Subject to the provisions of
the Plan, and in the case of a Committee, subject to the specific duties
delegated by the Board to such Committee, the Administrator shall have the
authority, in its discretion:

                     (i)     to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(n) of the Plan;

                     (ii)    to select the Consultants and Employees to whom
Options and Stock Purchase Rights may be granted hereunder;

                     (iii)   to determine whether and to what extent Options
and Stock Purchase Rights or any combination thereof, are granted hereunder;

                     (iv)    to determine the number of shares of Common Stock
to be covered by each Option and Stock Purchase Right granted hereunder;

                     (v)     to approve forms of agreement for use under the
Plan;

                     (vi)    to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder.  Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options or Stock Purchase Rights may be exercised (which may
be based on performance criteria), any vesting acceleration or waiver of


                                      -5-
<PAGE>   6
forfeiture restrictions, and any restriction or limitation regarding any Option
or Stock Purchase Right or the shares of Common Stock relating thereto, based
in each case on such factors as the Administrator, in its sole discretion,
shall determine;

                     (vii)   to reduce the exercise price of any Option or
Stock Purchase Right to the then current Fair Market Value if the Fair Market
Value of the Common Stock covered by such Option or Stock Purchase Right shall
have declined since the date the Option or Stock Purchase Right was granted;

                     (viii)  to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

                     (ix)    to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;

                     (x)     to modify or amend each Option or Stock Purchase
Right (subject to Section 15(c) of the Plan), including the discretionary
authority to extend the post-termination exercisability period of Options
longer than is otherwise provided for in the Plan;

                     (xi)    to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

                     (xii)   to institute an Option Exchange Program;

                     (xiii)  to determine the terms and restrictions applicable
to Options and Stock Purchase Rights and any Restricted Stock; and

                     (xiv)   to make all other determinations deemed necessary
or advisable for administering the Plan.

              (c)    Effect of Administrator's Decision.  The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

       5.     Eligibility.  Nonstatutory Stock Options and Stock Purchase
Rights may be granted to Employees and Consultants.  Incentive Stock Options
may be granted only to Employees.  If otherwise eligible, an Employee or
Consultant who has been granted an Option or Stock Purchase Right may be
granted additional Options or Stock Purchase Rights.

       6.     Limitations.

              (a)    Each Option shall be designated in the Notice of Grant as
either an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designations, to the extent that the aggregate Fair Market
Value:

                     (i)     of Shares subject to an Optionee's Incentive Stock
Options granted by the Company, any Parent or Subsidiary, which

                     (ii)    become exercisable for the first time during any
calendar year (under all plans of the Company or any Parent or Subsidiary)

exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock
Options.  For purposes of this Section 6(a), Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time of grant.

              (b)    Neither the Plan nor any Option or Stock Purchase Right
shall confer upon an Optionee any right with respect to continuing the
Optionee's employment or consulting relationship with the Company, nor shall
they interfere in any way with the Optionee's right or the Company's right to
terminate such employment or consulting relationship at any time, with or
without cause.

              (c)    The following limitations shall apply to grants of Options
and Stock Purchase Rights to Employees:

                     (i)     No Employee shall be granted, in any fiscal year
of the Company, Options and Stock Purchase Rights to purchase more than 200,000
Shares.

                     (ii)    The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization
as described in Section 13.

                     (iii)        If an Option or Stock Purchase Right is
canceled in the same fiscal year of the Company in which it was granted (other
than in connection with a transaction described in Section 13), the canceled
Option or Stock Purchase Right will be counted against the limit set forth in
Section 6(c)(i).  For this purpose, if the exercise price of an Option or Stock
Purchase Right is reduced, the transaction will be treated as a cancellation of
the Option or Stock Purchase Right and the grant of a new Option or Stock
Purchase Right.

       7.     Term of Plan.  Subject to Section 19 of the Plan, the Plan shall
become effective upon the earlier to occur of its adoption by the Board or its
approval by the shareholders of the Company as described in Section 19 of the
Plan.  It shall continue in effect for a term of ten (10) years unless
terminated earlier under Section 15 of the Plan.


                                      -7-
<PAGE>   8
       8.     Term of Option.  The term of each Option shall be stated in the
Notice of Grant; provided, however, that in the case of an Incentive Stock
Option, the term shall be ten (10) years from the date of grant or such shorter
term as may be provided in the Notice of Grant.  Moreover, in the case of an
Incentive Stock Option granted to an Optionee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the term of the Incentive Stock Option shall be five (5) years from
the date of grant or such shorter term as may be provided in the Notice of
Grant.

       9.     Option Exercise Price and Consideration.

              (a)    Exercise Price.  The per share exercise price for the
Shares to be issued pursuant to exercise of an Option shall be determined by
the Administrator, subject to the following:

                     (i)     In the case of an Incentive Stock Option

                             (A)  granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110%
of the Fair Market Value per Share on the date of grant.

                             (B)  granted to any Employee other than an
Employee described in paragraph (A) immediately above, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

                     (ii)    In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Administrator.

              (b)    Waiting Period and Exercise Dates.  At the time an Option
is granted, the Administrator shall fix the period within which the Option may
be exercised and shall determine any conditions which must be satisfied before
the Option may be exercised.  In so doing, the Administrator may specify that
an Option may not be exercised until the completion of a service period.

              (c)    Form of Consideration.  The Administrator shall determine
the acceptable form of consideration for exercising an Option, including the
method of payment.  In the case of an Incentive Stock Option, the Administrator
shall determine the acceptable form of consideration at the time of grant.
Such consideration may consist entirely of:

                     (i)     cash;

                     (ii)    check;


                                      -8-
<PAGE>   9
                     (iii)   promissory note;

                     (iv)    other Shares which (A) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six months on the date of surrender, and (B) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

                     (v)     delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price;

                     (vi)    a reduction in the amount of any Company liability
to the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                     (vii)   any combination of the foregoing methods of
payment; or

                     (viii)  such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws.

       10.    Exercise of Option.

              (a)    Procedure for Exercise; Rights as a Shareholder. Any
Option granted hereunder shall be exercisable according to the terms of the
Plan and at such times and under such conditions as determined by the
Administrator and set forth in the Option Agreement.

                     An Option may not be exercised for a fraction of a Share.

                     An Option shall be deemed exercised when the Company
receives: (i) written notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised.  Full
payment may consist of any consideration and method of payment authorized by
the Administrator and permitted by the Option Agreement and the Plan.  Shares
issued upon exercise of an Option shall be issued in the name of the Optionee
or, if requested by the Optionee, in the name of the Optionee and his or her
spouse.  Until the stock certificate evidencing such Shares is issued (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option.  The Company shall
issue (or cause to be issued) such stock certificate promptly after the Option
is exercised.  No adjustment will be made for a dividend or other right for
which the record date is prior to the date the stock certificate is issued,
except as provided in Section 13 of the Plan.


                                      -9-
<PAGE>   10
                     Exercising an Option in any manner shall decrease the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

              (b)    Termination of Employment or Consulting Relationship.
Upon termination of an Optionee's Continuous Status as an Employee or
Consultant, other than upon the Optionee's death or Disability, the Optionee
may exercise his or her Option, but only within such period of time as is
specified in the Notice of Grant, and only to the extent that the Optionee was
entitled to exercise it at the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Notice of Grant).
In the absence of a specified time in the Notice of Grant, the Option shall
remain exercisable for three months following the Optionee's termination of
Continuous Status as an Employee or Consultant.  In the case of an Incentive
Stock Option, such period of time shall not exceed three months from the date
of termination.  If, at the date of termination, the Optionee is not entitled
to exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall revert to the Plan.  If, after termination, the
Optionee does not exercise his or her Option within the time specified by the
Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

              (c)    Disability of Optionee.  In the event that an Optionee's
Continuous Status as an Employee or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option at any time
within twelve (12) months from the date of such termination, but only to the
extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant).  If, at the date of termination,
the Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered
by such Option shall revert to the Plan.

              (d)    Death of Optionee.  In the event of the death of an
Optionee, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Notice of Grant), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent that the Optionee was entitled to
exercise the Option at the date of death.  If, at the time of death, the
Optionee was not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall immediately revert to
the Plan.  If, after death, the Optionee's estate or a person who acquired the
right to exercise the Option by bequest or inheritance does not exercise the
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

              (e)    Rule 16b-3.  Options granted to individuals subject to
Section 16 of the Exchange Act ("Insiders") must comply with the applicable
provisions of Rule 16b-3 and shall contain such additional conditions or
restrictions as may be required thereunder to qualify for the maximum exemption
from Section 16 of the Exchange Act with respect to Plan transactions.

       11.    Stock Purchase Rights.

              (a)    Rights to Purchase.  Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan.  After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing, by means of a Notice of Grant, of the terms,
conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid,
and the time within which the offeree must accept such offer, which shall in no
event exceed six (6) months from the date upon which the Administrator made the
determination to grant the Stock Purchase Right.  The offer shall be accepted
by execution of a Restricted Stock Purchase Agreement in the form determined by
the Administrator.

              (b)    Repurchase Option.  Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's employment with the Company for any reason (including death or
Disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company.  The repurchase option shall lapse at a rate determined by the
Administrator.

              (c)    Rule 16b-3.  Stock Purchase Rights granted to Insiders,
and Shares purchased by Insiders in connection with Stock Purchase Rights,
shall be subject to any restrictions applicable thereto in compliance with Rule
16b-3.  An Insider may only purchase Shares pursuant to the grant of a Stock
Purchase Right, and may only sell Shares purchased pursuant to the grant of a
Stock Purchase Right, during such time or times as are permitted by Rule 16b-3.

              (d)    Other Provisions.  The Restricted Stock Purchase Agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.  In
addition, the provisions of Restricted Stock Purchase Agreements need not be
the same with respect to each purchaser.

              (e)    Rights as a Shareholder.  Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered
upon the records of the duly authorized transfer agent of the Company.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the Stock Purchase Right is exercised, except as provided
in Section 13 of the Plan.


                                      -11-
<PAGE>   12
       12.    Non-Transferability of Options and Stock Purchase Rights.  An
Option or Stock Purchase Right may not be sold, pledged, assigned,
hypothecated, transferred, or disposed of in any manner other than by will or
by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

       13.    Adjustments Upon Changes in Capitalization, Dissolution, Merger
              or Asset Sale.

              (a)    Changes in Capitalization.  Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock
covered by each outstanding Option and Stock Purchase Right, and the number of
shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options or Stock Purchase Rights have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option or Stock Purchase Right, as well as the price per share of Common Stock
covered by each such outstanding Option or Stock Purchase Right, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration."  Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive.  Except as expressly provided herein, no issuance by
the Company of shares of stock of any class, or securities convertible into
shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares of Common Stock
subject to an Option or Stock Purchase Right.

              (b)    Dissolution or Liquidation.  In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option or
Stock Purchase Right has not been previously exercised, it will terminate
immediately prior to the consummation of such proposed action.  The Board may,
in the exercise of its sole discretion in such instances, declare that any
Option or Stock Purchase Right shall terminate as of a date fixed by the Board
and give each Optionee the right to exercise his or her Option or Stock
Purchase Right as to all or any part of the Optioned Stock, including Shares as
to which the Option or Stock Purchase Right would not otherwise be exercisable.

              (c)    Merger or Asset Sale.  In the event of a merger of the
Company with or into another corporation, or the sale of substantially all of
the assets of the Company, each outstanding Option and Stock Purchase Right may
be assumed or an equivalent option or right may be substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation.  The
Administrator may, in lieu of such assumption or substitution, provide for the
Optionee to have the right to exercise the Option or Stock Purchase Right as to
all or a portion of the Optioned Stock, including Shares as to which it would
not otherwise be exercisable.  If the Administrator makes an Option or Stock
Purchase Right exercisable in lieu of assumption or substitution in the event
of a merger or sale of assets, the Administrator shall notify the Optionee that
the Option or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15)


                                      -12-
<PAGE>   13
days from the date of such notice, and the Option or Stock Purchase Right will
terminate upon the expiration of such period.  For the purposes of this
paragraph, the Option or Stock Purchase Right shall be considered assumed if,
following the merger or sale of assets, the option or right confers the right
to purchase, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received
in the merger or sale of assets by holders of Common Stock for each Share held
on the effective date of the transaction (and if holders were offered a choice
of consideration, the type of consideration chosen by the holders of a majority
of the outstanding Shares); provided, however, that if such consideration
received in the merger or sale of assets was not solely common stock of the
successor corporation or its Parent, the Administrator may, with the consent of
the successor corporation, provide for the consideration to be received upon
the exercise of the Option or Stock Purchase Right, for each Share of Optioned
Stock subject to the Option or Stock Purchase Right, to be solely common stock
of the successor corporation or its Parent equal in fair market value to the
per share consideration received by holders of Common Stock in the merger or
sale of assets.

       14.    Date of Grant.  The date of grant of an Option or Stock Purchase
Right shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator.  Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.

       15.    Amendment and Termination of the Plan.

              (a)    Amendment and Termination.  The Board may at any time
amend, alter, suspend or terminate the Plan.

              (b)    Shareholder Approval.  The Company shall obtain
shareholder approval of any Plan amendment to the extent necessary and
desirable to comply with Rule 16b-3 or with Section 422 of the Code (or any
successor rule or statute or other applicable law, rule or regulation,
including the requirements of any exchange or quotation system on which the
Common Stock is listed or quoted).  Such shareholder approval, if required,
shall be obtained in such a manner and to such a degree as is required by the
applicable law, rule or regulation.

              (c)    Effect of Amendment or Termination.  No amendment,
alteration, suspension or termination of the Plan shall impair the rights of
any Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee
and the Company.

       16.    Conditions Upon Issuance of Shares.

              (a)    Legal Compliance.  Shares shall not be issued pursuant to
the exercise of an Option or Stock Purchase Right unless the exercise of such
Option or Stock Purchase Right and the issuance and delivery of such Shares
shall comply with all relevant provisions of law,


                                      -13-
<PAGE>   14
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, Applicable
Laws, and the requirements of any stock exchange or quotation system upon which
the Shares may then be listed or quoted, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

              (b)    Investment Representations.  As a condition to the
exercise of an Option or Stock Purchase Right, the Company may require the
person exercising such Option or Stock Purchase Right to represent and warrant
at the time of any such exercise that the Shares are being purchased only for
investment and without any present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation is
required.

       17.    Liability of Company.

              (a)    Inability to Obtain Authority.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

              (b)    Grants Exceeding Allotted Shares.  If the Optioned Stock
covered by an Option or Stock Purchase Right exceeds, as of the date of grant,
the number of Shares which may be issued under the Plan without additional
shareholder approval, such Option or Stock Purchase Right shall be void with
respect to such excess Optioned Stock, unless shareholder approval of an
amendment sufficiently increasing the number of Shares subject to the Plan is
timely obtained in accordance with Section 15(b) of the Plan.

       18.    Reservation of Shares.  The Company, during the term of this
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

       19.    Shareholder Approval.  Continuance of the Plan shall be subject
to approval by the shareholders of the Company within twelve (12) months before
or after the date the Plan is adopted.  Such shareholder approval shall be
obtained in the manner and to the degree required under applicable federal and
state law.

I.     NOTICE OF INCENTIVE STOCK OPTION GRANT ("ISO")

       This Option may be exercised for thirty days after termination of the
Optionee's employment or consulting relationship with the Company.  Upon the

<PAGE>   16
Option Agreement shall remain in effect.  In no event shall this Option be
exercised later than the Expiration Date as provided above.

II.    AGREEMENT

       1.     Grant of Option.  The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee"), an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share
set forth in the Notice of Grant (the "Exercise Price"), subject to the terms
and conditions of the Plan, which is incorporated herein by reference.  Subject
to Section 15(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

              This Option is intended to qualify as an Incentive Stock Option
under Section 422 of the Code.  However, to the extent that it exceeds the
$100,000 rule of Code Section 422(d) it shall be treated as a Nonstatutory
Stock Option ("NSO").

       2.     Exercise of Option.

              (a)    Right to Exercise.  This Option is exercisable during its
term in accordance with the Vesting Schedule set out in the Notice of Grant and
the applicable provisions of the Plan and this Option Agreement.  In the event
of Optionee's death, Disability or other termination of Optionee's employment
or consulting relationship, the exercisability of the Option is governed by the
applicable provisions of the Plan and this Option Agreement.

              (b)    Method of Exercise.  This Option is exercisable by
delivery of an exercise notice, in the form attached as Exhibit A (the
"Exercise Notice"), which shall state the election to exercise the Option, the
number of Shares in respect of which the Option is being exercised (the
"Exercised Shares"), and such other representations and agreements as may be
required by the Company pursuant to the provisions of the Plan.  The Exercise
Notice shall be signed by the Optionee and shall be delivered in person or by
certified mail to the Vice President and Controller of the Company.  The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares.  This Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.

              No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with all relevant provisions of law
and the requirements of any stock exchange or quotation service upon which the
Shares are then listed.  Assuming such compliance, for income tax purposes the
Exercised Shares shall be considered transferred to the Optionee on the date
the Option is exercised with respect to such Exercised Shares.

<PAGE>   17
       3.     Method of Payment.  Payment of the aggregate Exercise Price shall
be by any of the following, or a combination thereof, at the election of the
Optionee:

              (a)    cash; or

              (b)    check; or

              (c)    delivery of a properly executed exercise notice together
with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price.

       4.     Non-Transferability of Option.  This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by the
Optionee.  The terms of the Plan and this Option Agreement shall be binding
upon the executors, administrators, heirs, successors and assigns of the
Optionee.

       5.     Term of Option.  This Option may be exercised only within the
term set out in the Notice of Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option Agreement.

       6.     Tax Consequences.  Some of the federal and California tax
consequences relating to this Option, as of the date of this Option, are set
forth below.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND
REGULATIONS ARE SUBJECT TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER
BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

              (a)    Exercising the Option.  The Optionee will have no regular
federal income tax or California income tax liability upon its exercise,
although the excess, if any, of the Fair Market Value of the Exercised Shares
on the date of exercise over their aggregate Exercise Price will be treated as
an adjustment to alternative minimum taxable income for federal tax purposes
and may subject the Optionee to alternative minimum tax in the year of
exercise.  In the event that the Optionee undergoes a change of status from
Employee to Consultant, any Incentive Stock Option of the Optionee that remains
unexercised shall cease to qualify as an Incentive Stock Option and will be
treated for tax purposes as a Nonstatutory Stock Option on the ninety-first
(91st) day following such change of status.

              (b)    Disposition of Shares.  If the Optionee holds ISO Shares
for at least one year after exercise AND two years after the grant date, any
gain realized on disposition of the Shares will be treated as long-term capital
gain for federal income tax purposes.  If the Optionee disposes of ISO Shares
within one year after exercise or two years after the grant date, any gain
realized on such disposition will be treated as compensation income (taxable at
ordinary income rates) to the extent of the excess, if any, of the LESSER OF
(A) the difference between the FAIR


                                      -3-
<PAGE>   18
MARKET VALUE OF THE SHARES ACQUIRED ON THE DATE OF EXERCISE and the aggregate
Exercise Price, or (B) the difference between the SALE PRICE of such Shares and
the aggregate Exercise Price.

              (c)    Notice of Disqualifying Disposition of ISO Shares.  If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii)
one year after the exercise date, the Optionee shall immediately notify the
Company in writing of such disposition.  The Optionee agrees that he or she may
be subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

       7.     Entire Agreement; Governing Law.  The Plan is incorporated herein
by reference.  The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the
Company and Optionee with respect to the subject matter hereof, and may not be
modified adversely to the Optionee's interest except by means of a writing
signed by the Company and Optionee.  This agreement is governed by California
law except for that body of law pertaining to conflict of laws.

       By your signature and the signature of the Company's representative
below, you and the Company agree that this Option is granted under and governed
by the terms and conditions of the Plan and this Option Agreement.  Optionee
has reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option
Agreement.  Optionee hereby agrees to accept as binding, conclusive and final
all decisions or interpretations of the Administrator upon any questions
relating to the Plan and Option Agreement.  Optionee further agrees to notify
the Company upon any change in the residence address indicated below.

              (a)    Exercising the Option. The Optionee may incur regular
federal income tax and California income tax liability upon exercise of a NSO.
The Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the Fair Market
Value of the Exercised Shares on the date of exercise over their aggregate
Exercise Price.  If the Optionee is an Employee or a former Employee, the
Company will be required to withhold from his or her compensation or collect
from Optionee and pay to the applicable taxing authorities an amount in cash
equal to a percentage of this compensation income at the time of exercise, and
may refuse to honor the exercise and refuse to deliver Shares if such
withholding amounts are not delivered at the time of exercise.

              (b)    Disposition of Shares.  If the Optionee holds NSO Shares
for at least one year, any gain realized on disposition of the Shares will be
treated as long-term capital gain for federal income tax purposes.

       7.     Entire Agreement; Governing Law.  The Plan is incorporated herein
by reference.  The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the
Company and Optionee with respect to the subject matter hereof, and may not be
modified adversely to the Optionee's interest except by means of a writing
signed by the Company and Optionee.  This agreement is governed by California
law except for that body of law pertaining to conflict of laws.

                               SECURITY AGREEMENT


       This Security Agreement is made as of __________, 19___ between Xicor,
Inc., a California corporation ("Pledgee"), and _________________________
("Pledgor").


                                    Recitals

       Pursuant to Pledgor's election to purchase Shares under the Option
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under
Pledgee's Amended and Restated 1990 Incentive and Non-Incentive Stock Option
Plan, and Pledgor's election under the terms of the Option to pay for such
shares with his promissory note (the "Note"), Pledgor has purchased _________
shares of Pledgee's Common Stock (the "Shares") at a price of $________ per
share, for a total purchase price of $__________.  The Note and the obligations
thereunder are as set forth in Exhibit C to the Option.

       NOW, THEREFORE, it is agreed as follows:

       1.     Creation and Description of Security Interest.  In consideration
of the transfer of the Shares to Pledgor under the Option Agreement, Pledgor,
pursuant to the California Commercial Code, hereby pledges all of such Shares
(herein sometimes referred to as the "Collateral") represented by certificate
number(s) ______, duly endorsed in blank or with executed stock powers, and
herewith delivers said certificate to the Vice President and Controller of
Pledgee ("Pledgeholder"), who shall hold said certificate subject to the terms
and conditions of this Security Agreement.

       The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Option, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

       2.     Pledgor's Representations and Covenants.  To induce Pledgee to
enter into this Security Agreement, Pledgor represents and covenants to
Pledgee, its successors and assigns, as follows:

              a.     Payment of Indebtedness.  Pledgor will pay the principal
sum of the Note secured hereby, together with interest thereon, at the time and
in the manner provided in the Note.
<PAGE>   26
              b.     Encumbrances.  The Shares are free of all other
encumbrances, defenses and liens, and Pledgor will not further encumber the
Shares without the prior written consent of Pledgee.

              c.     Margin Regulations.  In the event that Pledgee's Common
Stock is now or later becomes margin-listed by the Federal Reserve Board and
Pledgee is classified as a "lender" within the meaning of the regulations under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G"),
Pledgor agrees to cooperate with Pledgee in making any amendments to the Note
or providing any additional collateral as may be necessary to comply with such
regulations.

       3.     Voting Rights.  During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

       4.     Stock Adjustments.  In the event that during the term of the
pledge any stock dividend, reclassification, readjustment or other changes are
declared or made in the capital structure of Pledgee, all new, substituted and
additional shares or other securities issued by reason of any such change shall
be delivered to and held by the Pledgee under the terms of this Security
Agreement in the same manner as the Shares originally pledged hereunder.  In
the event of substitution of such securities, Pledgor, Pledgee and Pledgeholder
shall cooperate and execute such documents as are reasonable so as to provide
for the substitution of such Collateral and, upon such substitution, references
to "Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

       5.     Options and Rights.  In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held
under the terms of this Security Agreement in the same manner as the Shares
pledged.

       6.     Default.  Pledgor shall be deemed to be in default of the Note
and of this Security Agreement in the event:

              a.     Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

              b.     Pledgor fails to perform any of the covenants set forth in
the Option or contained in this Security Agreement for a period of 10 days
after written notice thereof from Pledgee.


                                      -2-
<PAGE>   27
       In the case of an event of Default, as set forth above, Pledgee shall
have the right to accelerate payment of the Note upon notice to Pledgor, and
Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

       7.     Release of Collateral.  Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note.  The number of the pledged Shares which shall be released shall be
that number of full Shares which bears the same proportion to the initial
number of Shares pledged hereunder as the payment of principal bears to the
initial full principal amount of the Note.

       8.     Withdrawal or Substitution of Collateral.  Pledgor shall not
sell, withdraw, pledge, substitute or otherwise dispose of all or any part of
the Collateral without the prior written consent of Pledgee.

       9.     Term.  The within pledge of Shares shall continue until the
payment of all indebtedness secured hereby, at which time the remaining pledged
stock shall be promptly delivered to Pledgor, subject to the provisions for
prior release of a portion of the Collateral as provided in paragraph 7 above.

       10.    Insolvency.  Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for
the property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due
and payable, and Pledgee may proceed as provided in the case of default.

       11.    Pledgeholder Liability.  In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

       12.    Invalidity of Particular Provisions.  Pledgor and Pledgee agree
that the enforceability or invalidity of any provision or provisions of this
Security Agreement shall not render any other provision or provisions herein
contained unenforceable or invalid.

       13.    Successors or Assigns.  Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective
successors and assigns, and that the term "Pledgor" and the term "Pledgee" as
used herein shall be deemed to include, for all purposes, the respective
designees, successors, assigns, heirs, executors and administrators.

                               STOCK OPTION PLAN

                      RESTRICTED STOCK PURCHASE AGREEMENT

       Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Restricted Stock Purchase Agreement.

       WHEREAS the Purchaser named in the Notice of Grant, (the "Purchaser") is
an employee or consultant of the Company, and the Purchaser's continued
participation is considered by the Company to be important for the Company's
continued growth; and

       WHEREAS in order to give the Purchaser an opportunity to acquire an
equity interest in the Company as an incentive for the Purchaser to participate
in the affairs of the Company, the Administrator has granted to the Purchaser
stock purchase rights subject to the terms and conditions of the Plan and the
Notice of Grant, which are incorporated herein by reference, and pursuant to
this restricted stock purchase agreement (the "Agreement").

       THEREFORE, the parties agree as follows:

       1.     Sale of Stock.  The Company hereby agrees to sell to the
Purchaser and the Purchaser hereby agrees to purchase shares of the Company's
Common Stock (the "Shares"), at the per share purchase price and as otherwise
described in the Notice of Grant.

       2.     Payment of Purchase Price.  The purchase price for the Shares may
be paid by delivery to the Company at the time of execution of this Agreement
of cash, a check, or some combination thereof.

       3.     Repurchase Option.

              (a)    In the event the Purchaser's Continuous Status as an
Employee or Consultant terminates for any or no reason (including death or
disability) before all of the Shares are released from the Company's repurchase
option (see Section 4), the Company shall, upon the date of such termination
(as reasonably fixed and determined by the Company) have an irrevocable,
exclusive option for a period of sixty (60) days from such date to repurchase
up to that number of shares which constitute the Unreleased Shares (as defined
in Section 4) at the original purchase price per share (the "Repurchase
Price").  Said option shall be exercised by the Company by delivering written
notice to the Purchaser or the Purchaser's executor (with a copy to the Escrow
Holder) AND, at the Company's option, (i) by delivering to the Purchaser or the
Purchaser's executor a check in the amount of the aggregate Repurchase Price,
or (ii) by the Company canceling an amount of the Purchaser's indebtedness to
the Company equal to the


<PAGE>   32
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price.  Upon delivery of such notice and the payment of the
aggregate Repurchase Price in any of the ways described above, the Company
shall become the legal and beneficial owner of the Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall
have the right to retain and transfer to its own name the number of Shares
being repurchased by the Company.

              (b)    Whenever the Company shall have the right to repurchase
Shares hereunder, the Company may designate and assign one or more employees,
officers, directors or shareholders of the Company or other persons or
organizations to exercise all or a part of the Company's purchase rights under
this Agreement and purchase all or a part of such Shares; provided that if the
Fair Market Value of the Shares to be repurchased on the date of such
designation or assignment (the "Repurchase FMV") exceeds the aggregate
Repurchase Price of such Shares, then each such designee or assignee shall pay
the Company cash equal to the difference between the Repurchase FMV and the
aggregate Repurchase Price of such Shares.

       4.     Release of Shares From Repurchase Option.

              (a)    ___________________ (_______) of the Shares shall be
released from the Company's repurchase option
__________________________________________________________, provided in each
case that the Purchaser's Continuous Status as an Employee or Consultant has
not terminated prior to the date of any such release.

              (b)    Any of the Shares which have not yet been released from
the Company's repurchase option are referred to herein as "Unreleased Shares."

              (c)    The Shares which have been released from the Company's
repurchase option shall be delivered to the Purchaser at the Purchaser's
request (see Section 6).

       5.     Restriction on Transfer.  Except for the escrow described in
Section 6 or transfer of the Shares to the Company or its assignees
contemplated by this Agreement, none of the Shares or any beneficial interest
therein shall be transferred, encumbered or otherwise disposed of in any way
until the release of such Shares from the Company's repurchase option in
accordance with the provisions of this Agreement, other than by will or the
laws of descent and distribution.

       6.     Escrow of Shares.

              (a)    To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon repurchase by the Company pursuant to the Company's
repurchase option under Section 3 above, the Purchaser shall, upon execution of
this Agreement, deliver and deposit with an escrow holder designated by the
Company (the "Escrow Holder") the share certificates representing the
Unreleased Shares, together with the stock assignment duly endorsed in blank,
attached hereto as Exhibit A-2.  The Unreleased Shares and stock assignment
shall be held by


                                      -2-
<PAGE>   33
the Escrow Holder, pursuant to the Joint Escrow Instructions of the Company and
Purchaser attached as Exhibit A-3 hereto, until such time as the Company's
repurchase option expires.

              (b)    The Escrow Holder shall not be liable for any act it may
do or omit to do with respect to holding the Unreleased Shares in escrow and
while acting in good faith and in the exercise of its judgment.

              (c)    If the Company or any assignee exercises its repurchase
option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

              (d)    When the repurchase option has been exercised or expires
unexercised or a portion of the Shares has been released from such repurchase
option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

              (e)    Subject to the terms hereof, the Purchaser shall have all
the rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon.  If, from time to time during the term of
the Company's repurchase option, there is (i) any stock dividend, stock split
or other change in the Shares, or (ii) any merger or sale of all or
substantially all of the assets or other acquisition of the Company, any and
all new, substituted or additional securities to which the Purchaser is
entitled by reason of the Purchaser's ownership of the Shares shall be
immediately subject to this escrow, deposited with the Escrow Holder and
included thereafter as "Shares" for purposes of this Agreement and the
Company's repurchase option.

       7.     Legends.  The share certificate evidencing the Shares issued
hereunder shall be endorsed with the following legend (in addition to any
legend required under applicable state securities laws):

       THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN
AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE
WITH THE SECRETARY OF THE COMPANY.

       8.     Adjustment for Stock Split.  All references to the number of
Shares and the purchase price of the Shares in this Agreement shall be
appropriately adjusted to reflect any stock split, stock dividend or other
change in the Shares which may be made by the Company after the date of this
Agreement.

       9.     Tax Consequences.  The Purchaser has reviewed with the
Purchaser's own tax advisors the federal, state, local and foreign tax
consequences of this investment and the transactions contemplated by this
Agreement.  The Purchaser is relying solely on such advisors


                                      -3-
<PAGE>   34
and not on any statements or representations of the Company or any of its
agents.  The Purchaser understands that the Purchaser (and not the Company)
shall be responsible for the Purchaser's own tax liability that may arise as a
result of this investment or the transactions contemplated by this Agreement.
The Purchaser understands that Section 83 of the Internal Revenue Code of 1986,
as amended (the "Code"), taxes as ordinary income the difference between the
purchase price for the Shares and the Fair Market Value of the Shares as of the
date any restrictions on the Shares lapse.  In this context, "restriction"
includes the right of the Company to buy back the Shares pursuant to its
repurchase option.  The Purchaser understands that the Purchaser may elect to
be taxed at the time the Shares are purchased rather than when and as the
Company's repurchase option expires by filing an election under Section 83(b)
of the Code with the I.R.S. within 30 days from the date of purchase.  The form
for making this election is attached as Exhibit A-5 hereto.

              THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO
MAKE THIS FILING ON THE PURCHASER'S BEHALF.

       10.    General Provisions.

              (a)    This Agreement shall be governed by the laws of the State
of California.  This Agreement, subject to the terms and conditions of the Plan
and the Notice of Grant, represents the entire agreement between the parties
with respect to the purchase of Common Stock by the Purchaser.  Subject to
Section 15(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Agreement, the
terms and conditions of the Plan shall prevail.  Unless otherwise defined
herein, the terms defined in the Plan shall have the same defined meanings in
this Agreement.

              (b)    Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end
of this Agreement or such other address as a party may request by notifying the
other in writing.

              Any notice to the Escrow Holder shall be sent to the Company's
address with a copy to the other party not sending the notice.

              (c)    The rights and benefits of the Company under this
Agreement shall be transferable to any one or more persons or entities, and all
covenants and agreements hereunder shall inure to the benefit of, and be
enforceable by the Company's successors and assigns.  The rights and
obligations of the Purchaser under this Agreement may only be assigned with the
prior written consent of the Company.


                                      -4-
<PAGE>   35
              (d)    Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor prevent that party from thereafter
enforcing each and every other provision of this Agreement.  The rights granted
both parties herein are cumulative and shall not constitute a waiver of either
party's right to assert all other legal remedies available to it under the
circumstances.

              (e)    The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

              (f)    PURCHASER ACKNOWLEDGES AND AGREES THAT THE VESTING OF
SHARES PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS AN
EMPLOYEE OR CONSULTANT AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING
HIRED OR PURCHASING SHARES HEREUNDER).  PURCHASER FURTHER ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE
VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED
PROMISE OF CONTINUED ENGAGEMENT AS AN EMPLOYEE OR CONSULTANT FOR THE VESTING
PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH PURCHASER'S
RIGHT OR THE COMPANY'S RIGHT TO TERMINATE PURCHASER'S EMPLOYMENT OR CONSULTING
RELATIONSHIP AT ANY TIME, WITH OR WITHOUT CAUSE.

       By Purchaser's signature below, Purchaser represents that he or she is
familiar with the terms and provisions of the Plan, and hereby accepts this
Agreement subject to all of the terms and provisions thereof.  Purchaser has
reviewed the Plan and this Agreement in their entirety, has had an opportunity
to obtain the advice of counsel prior to executing this Agreement and fully
understands all provisions of this Agreement.  Purchaser agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Agreement.
Purchaser further agrees to notify the Company upon any change in the residence
indicated in the Notice of Grant.

Dear _________________:

       As Escrow Agent for both Xicor, Inc., a California corporation (the
"Company"), and the undersigned purchaser of stock of the Company (the
"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Restricted Stock
Purchase Agreement ("Agreement") between the Company and the undersigned, in
accordance with the following instructions:

       1.     In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the "Company") exercises
the Company's repurchase option set forth in the Agreement, the Company shall
give to Purchaser and you a written notice specifying the number of shares of
stock to be purchased, the purchase price, and the time for a closing hereunder
at the principal office of the Company.  Purchaser and the Company hereby
irrevocably authorize and direct you to close the transaction contemplated by
such notice in accordance with the terms of said notice.

       2.     At the closing, you are directed (a) to date the stock
assignments necessary for the transfer in question, (b) to fill in the number
of shares being transferred, and (c) to deliver same, together with the
certificate evidencing the shares of stock to be transferred, to the Company or
its assignee, against the simultaneous delivery to you of the purchase price
(by cash, a check, or some combination thereof) for the number of shares of
stock being purchased pursuant to the exercise of the Company's repurchase
option.

       3.     Purchaser irrevocably authorizes the Company to deposit with you
any certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky
authority of any required applications for consent to, or notice of transfer
of, the securities.  Subject to the provisions of this paragraph 3, Purchaser
<PAGE>   38
shall exercise all rights and privileges of a shareholder of the Company while
the stock is held by you.

       4.     Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's repurchase option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's repurchase option.
Within 30 days after cessation of Purchaser's continuous employment by or
services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's repurchase
option.

       5.     If at the time of termination of this escrow you should have in
your possession any documents, securities, or other property belonging to
Purchaser, you shall deliver all of the same to Purchaser and shall be
discharged of all further obligations hereunder.

       6.     Your duties hereunder may be altered, amended, modified or
revoked only by a writing signed by all of the parties hereto.

       7.     You shall be obligated only for the performance of such duties as
are specifically set forth herein and may rely and shall be protected in
relying or refraining from acting on any instrument reasonably believed by you
to be genuine and to have been signed or presented by the proper party or
parties.  You shall not be personally liable for any act you may do or omit to
do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting
in good faith, and any act done or omitted by you pursuant to the advice of
your own attorneys shall be conclusive evidence of such good faith.

       8.     You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of
any court.  In case you obey or comply with any such order, judgment or decree,
you shall not be liable to any of the parties hereto or to any other person,
firm or corporation by reason of such compliance, notwithstanding any such
order, judgment or decree being subsequently reversed, modified, annulled, set
aside, vacated or found to have been entered without jurisdiction.

       9.     You shall not be liable in any respect on account of the
identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers
deposited or called for hereunder.

       10.    You shall not be liable for the outlawing of any rights under the
Statute of Limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

experts as you may deem necessary properly to advise you in connection with
your obligations hereunder, may rely upon the advice of such counsel, and may
pay such counsel reasonable compensation therefor.

       12.    Your responsibilities as Escrow Agent hereunder shall terminate
if you shall cease to be an officer or agent of the Company or if you shall
resign by written notice to each party.  In the event of any such termination,
the Company shall appoint a successor Escrow Agent.

       13.    If you reasonably require other or further instruments in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

       14.    It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or
defend any such proceedings.

       15.    Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
