                       REGISTRATION STATEMENT ON FORM S-8

           PART II: INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents filed with the Securities and Exchange
Commission (the "Commission") are incorporated herein by reference:

         (a)      The Registrant's Annual Report on Form 10-K for the fiscal
                  year ended March 31, 1998 filed on June 26, 1998 pursuant to
                  Section 13(a) of the Securities Exchange Act of 1934, as
                  amended (the "Exchange Act"), which contains audited financial
                  statements for the Registrant's fiscal year ended March 31,
                  1998.

         (b)      The Registrant's Quarterly Report on Form 10-Q for the fiscal
                  quarter ended June 30, 1998 filed on August 14, 1998 pursuant
                  to Section 13(a) of the Exchange Act.

         (c)      The description of the Registrant's Common Stock contained in
                  the Registrant's Registration Statement on Form 8-A (File No.
                  0-23926) filed with the Commission on April 23, 1994 under
                  Section 12(g) of the Exchange Act, including any amendment or
                  report filed for the purpose of updating such description.

         All documents subsequently filed by the Registrant pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment which indicates that all securities registered hereby
have been sold or which deregisters all securities then remaining unsold, shall
be deemed incorporated by reference herein and to be a part hereof from the date
of the filing of such documents.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         As permitted by Section 145 of the Delaware General Corporation Law,
the Registrant's Certificate of Incorporation includes a provision that
eliminates the personal liability of its directors to the Registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
that involve intentional misconduct or a knowing violation of law, (iii) under
section 174 of the Delaware General Corporation Law or (iv) for any transaction
from which the director derived an improper personal benefit. In addition, as
permitted by Section 145 of the Delaware General Corporation Law, the Bylaws of
the Registrant provide that: (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law; (ii) the Registrant may, in its discretion, indemnify other
employees and agents as set forth in the Delaware General Corporation Law; (iii)
upon receipt of an undertaking to repay such 


                                    -PAGE 2-

<PAGE>   3

advances if indemnification is determined by final judicial decision from which
there is no further right to appeal, the Registrant is required to advance
expenses, as incurred, to its directors and officers to the fullest extent
permitted by the Delaware General Corporation Law in connection with a
proceeding; and (iv) the rights conferred in the Bylaws are not exclusive and
the Registrant is authorized to enter into indemnification agreements with its
directors, officers and employees and agents.

         The Registrant has entered into indemnification agreements with each of
its directors and executive officers. The indemnification agreements provide
that directors and executive officers will be indemnified and held harmless to
the fullest possible extent permitted by law including against all expenses
(including attorneys' fees), judgments, penalties, fines and settlement amounts
paid (including all interest, assessments and other charges paid or payable in
connection with or in respect of such expenses, judgments, penalties, fines and
amounts paid in settlement) or reasonably incurred by them in any action, suit
or proceeding, including any derivative action by or in the right of the
Registrant, on account of their services as directors, officers, employees or
agents of the Registrant or as directors, officers, employees or agents of any
other company or enterprise when they are serving in such capacities at the
request of the Registrant. The Registrant will not be obligated pursuant to the
agreements to indemnify or advance expenses to an indemnified party with respect
to proceedings or claims initiated by the indemnified party (other than a
proceeding to enforce his or her rights under the indemnification agreement)
except with respect to a proceeding authorized by the Board of Directors

         The indemnification agreement requires a director or executive officer
to reimburse the Registrant for expenses advanced only to the extent it is
ultimately determined that the director or executive officer is not entitled,
under Delaware law, the Bylaws, his or her indemnification agreement or
otherwise to be indemnified for such expenses. The indemnification agreement
provides that it is not exclusive of any rights a director or executive officer
may have under the Certificate of Incorporation, Bylaws, other agreements, any
majority-in-interest vote of the stockholders or vote of disinterested
directors, the Delaware law, or otherwise.

         The indemnification provision in the Bylaws, and the indemnification
agreements entered into between the Registrant and its directors and executive
officers, may be sufficiently broad to permit indemnification of the
Registrant's directors and executive officers for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act"). As authorized by the
Registrant's Bylaws, the Registrant, with approval by the Registrant's Board of
Directors, maintains directors and officers liability insurance with a per claim
and annual aggregate coverage limit of up to $20,000,000.

         Pursuant to underwriting agreements among the Registrant and the
underwriters of the Registrant's initial public offering dated June 22, 1994 and
a subsequent public offering dated November 14, 1995, the Registrant's officers
and directors and other persons who control the Registrant are indemnified
against any and all losses, claims, damages or liabilities to which such persons
may become subject under the Securities Act, Exchange Act and common law which
arise out of any untrue statement regarding or omission of a material fact
contained in the registration statement for such offerings if such statement or
omission was made in reliance upon and in conformity with information provided
to the Registrant in writing by any underwriter of the offering.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable.

ITEM 9.  UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

                  (i)  To include any prospectus required by Section 10(a)(3) of
the Securities Act;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in the volume
of securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low and high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a twenty percent (20%) change
in the maximum aggregate offering price set forth 



                                    -PAGE 4-
<PAGE>   5

in the "Calculation of Registration Fee" table in the effective registration
statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the
Registration Statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions discussed in Item 6 hereof, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereby, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

         1. Purposes of the Plan. The purposes of this Stock Plan are to attract
and retain the best available personnel for positions of substantial

Outside Directors of the Company and its Subsidiaries and to promote the success
of the Company's business by granting Options and Performance Awards. Options
granted under the Plan may be incentive stock options (as defined under Section
422 of the Code) or non-statutory stock options, as determined by the
Administrator at the time of grant of an option and subject to the applicable
provisions of Section 422 of the Code, as amended, and the regulations
promulgated thereunder. The Plan also provides for automatic grants of
Nonstatutory Stock Options to Outside Directors. Performance Awards granted
under the Plan may be cash or stock bonus awards granted either alone, in
addition to or in tandem with other awards granted under the Plan and/or awards
made outside the Plan.

         4. Administration of the Plan.

                  (a) Procedure.

                              (i) Administration With Respect to Directors and
Officers. With respect to grants of Options or Performance Awards to Employees
who are officers or directors of the Company and Outside Directors, the Plan
shall be administered by (A) the Board if the Board may administer the Plan in
compliance with Rule 16b-3 promulgated under the Exchange Act or any successor
thereto ("Rule 16b-3") with respect to a plan intended to qualify thereunder as
a discretionary plan, or (B) a Committee designated by the Board to 



                                       3
<PAGE>   4

administer the Plan, which Committee shall be constituted in such a manner as to
permit the Plan to comply with Rule 16b-3 with respect to a plan intended to
qualify thereunder as a discretionary plan. 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 thereof, remove members (with or without cause) and
appoint new members in substitution therefor, fill vacancies, however caused,
and remove all members of the Committee and thereafter directly administer the
Plan, all to the extent permitted by Rule 16b-3 with respect to a plan intended
to qualify thereunder as a discretionary plan.

                              (ii) Multiple Administrative Bodies. If permitted
by Rule 16b-3, the Plan may be administered by different bodies with respect to
directors, non-director officers and Employees who are neither directors nor
officers.

                              (iii) Administration With Respect to Consultants
and Other Employees. With respect to grants of Options or Performance Awards to
Employees or Consultants who are neither directors nor 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 in such a manner as to satisfy
the legal requirements relating to the administration of incentive stock option
plans, if any, of California corporate and securities laws and of the Code (the
"Applicable Laws"). 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
thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies, however caused, and remove all members of
the Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.

                  (b) Powers of the Administrator. Subject to the provisions of
the Plan and in the case of a Committee, 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(k) of the Plan;

                              (ii) to select the officers, Consultants and
Employees to whom Options or Performance Awards may from time to time be granted
hereunder;

                              (iii) to determine whether and to what extent
Options or Performance Awards are granted hereunder;

                              (iv) to determine the number of shares of Common
Stock to be covered by each such award granted hereunder;



                                       4
<PAGE>   5

                              (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
(including, but not limited to, the share price and any restriction or
limitation, or any vesting acceleration or waiver of forfeiture restrictions
regarding any Option and/or the shares of Common Stock relating thereto, based
in each case on such factors as the Administrator shall determine, in its sole
discretion);

                              (vii) to determine whether and under what
circumstances an Option may be settled in cash under subsection 9(f) instead of
Common Stock;

                              (viii) to determine whether, to what extent and
under what circumstances Common Stock and other amounts payable with respect to
an award under this Plan shall be deferred either automatically or at the
election of the participant (including providing for and determining the amount,
if any, of any deemed earnings on any deferred amount during any deferral
period); and

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

                  (c) Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

         5. Eligibility.

                  (a) Nonstatutory Stock Options and Performance Awards may be
granted to Employees, Consultants and Outside Directors. Incentive Stock Options
may be granted only to Employees. An Employee, Consultant or Outside Director
who has been granted an Option or Performance Award may, if he is otherwise
eligible, be granted additional Options and Performance Awards.

                  (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
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.

                  (c) For purposes of Section 5(b), Incentive Stock Options
shall be taken into account in the order in which they were granted, and the
Fair Market Value of the 



                                       5
<PAGE>   6

Shares shall be determined as of the time the Option with respect to such Shares
is granted.

                  (d) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment or consulting relationship with the
Company, nor shall it interfere in any way with his or her right or the
Company's right to terminate his or her employment or consulting relationship at
any time, with or without cause.

         6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors 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 sooner terminated under
Section 15 of the Plan.

         7. Term of Option. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that in the case of an Incentive Stock
Option, the term shall be no more than ten (10) years from the date of grant
thereof or such shorter term as may be provided in the Option Agreement.
However, in the case of an Option granted to an Optionee who, at the time the
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 Option shall be five (5) years from the date of grant thereof or
such shorter term as may be provided in the Option Agreement.


         8. Option Exercise Price and Consideration.

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

                              (i) In the case of an Incentive Stock Option

                                    (A) granted to an Employee who, at the time
of the grant of such Incentive Stock Option, 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, 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

                                    (A) granted to a person who, at the time of
the grant of such Option, owns stock representing more than ten percent (10%) of
the voting power of all 



                                       6
<PAGE>   7

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 the grant.

                                    (B) granted to any person, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on
the date of grant.

                  (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option either have been owned by the Optionee for
more than six months on the date of surrender or were not acquired, directly or
indirectly, from the Company, and (y) 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, (5) delivery of a properly executed exercise notice
together with irrevocable instructions to a broker to promptly deliver to the
Company the amount of sale or loan proceeds required to pay the exercise price,
(6) by delivering an irrevocable subscription agreement for the Shares which
irrevocably obligates the option holder to take and pay for the Shares not more
than twelve months after the date of delivery of the subscription agreement, (7)
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; (8) any combination of the
foregoing methods of payment, (9) or such other consideration and method of
payment for the issuance of Shares to the extent permitted under Applicable
Laws. In making its determination as to the type of consideration to accept, the
Board shall consider if acceptance of such consideration may be reasonably
expected to benefit the Company (Section 315(b) of the California corporation
law).

         9. Exercise of Option.

                  (a) Procedure for Exercise; Rights as a Shareholder. Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Board, including performance criteria with
respect to the Company and/or the Optionee, and as shall be permissible under
the terms of the Plan.

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

                           An Option shall be deemed to be exercised when 
written notice of such exercise has been given to the Company in accordance with
the terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 8(b) of the
Plan. Until the issuance (as evidenced by the appropriate entry 



                                       7
<PAGE>   8

on the books of the Company or of a duly authorized transfer agent of the
Company) of the stock certificate evidencing such Shares, 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 upon
exercise of the Option. 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 11 of the Plan.

                           Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be 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. In the event of termination of
an Optionee's Continuous Status as an Employee, Consultant or Outside Director,
such Optionee may, but only within thirty (30) days, or within such other period
of time as is determined by the Board, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option and such
time period not exceeding ninety (90) days) after the date of such termination
(but in no event later than the expiration date of the term of such Option as
set forth in the Option Agreement), exercise his Option to the extent that
Optionee was entitled to exercise it at the date of such termination. To the
extent that Optionee was not entitled to exercise the Option at the date of such
termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.

                  (c) Disability of Optionee. Notwithstanding the provisions of
Section 9(b) above, in the event of termination of an Optionee's Continuous
Status as an Employee, Consultant or Outside Director as a result of his
disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only
within twelve (12) months from the date of such termination (but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise the Option to the extent otherwise entitled to
exercise it at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate.

                  (d) Death of Optionee. In the event of the death of an
Optionee while Optionee is an Employee, Consultant or Outside Director, 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 date of the term of such
Option as set forth in the Option Agreement), 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 the Optionee was entitled to exercise the Option at the
date of death. To the extent that Optionee was not entitled to exercise the
Option at the date of death, or if Optionee does not exercise such Option to the
extent so entitled within the time specified herein, the Option shall terminate.



                                       8
<PAGE>   9

                  (e) Rule 16b-3. Options granted to persons subject to Section
16(b) of the Exchange Act must comply with 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.

                  (f) Buyout Provisions. The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10. Non-Transferability of Options and Performance Awards. Options and
Performance Awards 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.

         11. Adjustments Upon Changes in Capitalization or Merger. Subject to
any required action by the shareholders of the Company, the number of shares of
Common Stock covered by each outstanding Option or Performance Award, and the
number of shares of Common Stock which have been authorized for issuance under
the Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per share of Common Stock covered by each such outstanding Option,
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.

                  In the event of the proposed dissolution or liquidation of the
Company, the Board shall notify the Optionee at least fifteen (15) days prior to
such proposed action. To the extent it has not been previously exercised, the
Option will terminate immediately prior to the consummation of such proposed
action. In the event of a merger of the Company with or into another
corporation, the Option shall be assumed or an equivalent option shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation. In the event that such successor corporation does not
agree to assume the Option or to substitute an equivalent option, the Board
shall, in lieu of such assumption or substitution, provide for the Optionee to
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which the Option would not otherwise be 



                                       9
<PAGE>   10

exercisable. If the Board makes an Option fully exercisable in lieu of
assumption or substitution in the event of a merger, the Board shall notify the
Optionee that the Option shall be fully exercisable for a period of fifteen (15)
days from the date of such notice, and the Option will terminate upon the
expiration of such period.

         12. Limitation on Number of Option Shares. The following limitations
shall apply to grants of options to Employees hereunder:

                  (a) No Employee shall be granted, in any fiscal year of the
Company, options to purchase more than 250,000 shares of Common Stock.

                  (b) The foregoing limitation shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 11 hereof.

                  (c) If an option 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 11), the canceled option will be counted against the limit
set forth in Section 12 (a) above. For this purpose, if the exercise price of an
option is reduced, the transaction will be treated as a cancellation of the
option and the grant of a new option.

         13. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board. Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

         14. Performance Awards.

                  (a) Performance Awards are cash or stock bonus awards that may
be granted either alone, in addition to or in tandem with other awards granted
under the Plan and/or awards made outside of the Plan. Performance Awards shall
not require payment by the recipient of any consideration for the Performance
Award or for the shares of Common Stock covered by such award. The Board or a
committee created by the Board for the purpose of administering Performance
Awards (the "Performance Award Committee") in accordance with Section 4 shall
determine the performance and/or employment factors to be used in the
determination of the amount of Performance Awards and the extent to which such
Performance Awards have been earned. Shares issued pursuant to a Performance
Award may be made subject to various conditions, including vesting or forfeiture
provisions. Performance Awards may vary from participant to participant and
between groups of participants and shall be based upon the achievement of
Company and/or individual performance factors or upon such other criteria as the
Performance Award Committee may deem appropriate.

                  (b) Adjustment of Awards. The Performance Award Committee may,
after 



                                       10
<PAGE>   11

the grant of Performance Awards, adjust the performance factors applicable to
such Performance Awards to take into account changes in the law or in accounting
or tax rules and to make such adjustments as the Committee deems necessary or
appropriate to reflect the inclusion or exclusion of the impact of extraordinary
or unusual items, events or circumstances in order to avoid windfalls or
hardships.

                  The foregoing amendment shall become effective as of September
1, 1995, subject to shareholder approval at the Company's August 29, 1995 annual
meeting of shareholders.

         15. Amendment and Termination of the Plan.

                  (a) Amendment and Termination. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of the NASD or an established stock
exchange), the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as required.

                  (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

         16. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option 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 rules and regulations promulgated
thereunder, 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.

                  As a condition to the exercise of an Option, the Company may
require the person exercising such Option 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 by any of
the aforementioned relevant provisions of law.

         17. 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.



                                       11
<PAGE>   12

                  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.

         18. Agreements. Options and Performance Awards shall be evidenced by
written agreements in such form as the Board shall approve from time to time.

         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 degree and manner required under applicable state and federal law and the
rules of any stock exchange upon which the Common Stock is listed.

                              Geoworks Corporation

                          Employee Stock Purchase Plan
                                  Plan Document

                    (As amended and restated April 23, 1998)


The following constitute the provisions of the Employee Stock Purchase Plan (the
"Plan") of Geoworks Corporation.

1.        Purpose. The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company through accumulated payroll deductions. It is the intention
of the Company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

2.       Definitions.

         a. "Board" shall mean the Board of Directors of the Company.

         b. "Code" shall mean the Internal Revenue Code of 1986, as amended.

         c. "Common Stock" shall mean the Common Stock of the Company.

         d. "Company" shall mean Geoworks Corporation, a Delaware corporation.

         e. "Compensation" shall mean all base straight time gross earnings,
payments for overtime, shift premium, incentive compensation, incentive
payments, bonuses, and commissions.

         f. "Designated Subsidiaries" shall be the Subsidiaries, if any, which
have been designated by the Board from time to time in its sole discretion as
eligible to participate in the Plan.

         g. "Employee" shall mean any individual who is an employee of the
Company for purposes of tax withholding under the Code whose customary
employment with the Company or any Designated Subsidiary is at least twenty (20)
hours per week and more than five (5) months in any calendar year. For purposes
of the Plan, the employment relationship shall be treated as continuing intact
while the individual is on sick leave or other leave of absence approved by the
Company. Where the period of leave exceeds ninety (90) days and the individual's
right to re-employment is not guaranteed either by statute or by contract, the
employment relationship will be deemed to have terminated on the 



<PAGE>   2

91st day of such leave.

         h. "Enrollment Date" shall mean the first day of each Offering Period.

         i. "Exercise Date" shall mean the last day of each Offering Period, or,
with respect to an Extended Offering Period shall mean the last day of each
Purchase Period.

         j. "Extended Offering Period" shall mean a period of approximately
twenty-four (24) months, commencing on the date or dates so specified by the
Board, during which options granted pursuant to the Plan may be exercised. The
duration, commencement and termination of Extended Offering Periods may be
changed pursuant to Section 4 of this Plan.

         k. "Fair Market Value" shall mean, as of any date, the value of Common
Stock determined as follows:

                  1. If the Common Stock is listed on any established stock
exchange or a national market system, including without limitation the National
Market of the National Association of Securities Dealers, Inc. Automated
Quotation ("NASDAQ") System, its Fair Market Value shall be the closing sales
price for the Common Stock (or the closing bid, if no sales were reported) as
quoted on such system or exchange (or the exchange with the greatest volume of
trading in Common Stock) on the date of such determination (or, if not a market
trading day, then the last market trading day prior to the date of
determination), as reported in The Wall Street Journal or such other source as
the Board deems reliable; or

                  2. If the Common Stock is quoted on the NASDAQ system (but not
on the National Market system thereof) or is regularly quoted by a recognized
securities dealer but selling prices are not reported, its Fair Value shall be
the mean between the high bid and low asked prices for the Common Stock on the
date of such determination), as reported in The Wall Street Journal or such
other source as the Board deems reliable; or

                  3. Notwithstanding paragraphs (1) and (2), in the case of an
Offering Period commencing substantially concurrent with the Company's initial
public offering, the Fair Market Value may be determined by the Board to be
equal to the initial price to the public of shares of Common Stock in such
offering; or

                  4. In the absence of an established market for the Common
Stock, the Fair Market Value thereof shall be determined in good faith by the
Board.

         l. "Offering Period" shall mean a period of approximately six (6)



<PAGE>   3

months, commencing on the first Trading Day on or after August 1 and the last
Trading Day in the period ending the following January 31, or commencing on the

in the period ending the following July 31 during which options granted pursuant
to the Plan may be exercised. The duration, commencement and termination of
Offering Periods may be changed pursuant to Section 4 of this Plan.
Notwithstanding the foregoing, in the event the Company shall effect an initial
public offering of Common Stock, the Board may determine to commence an Offering
Period substantially concurrent with the public offering, such Offering Period
to continue until the next succeeding January 31 or July 31 as the Board may
determine.

         m. "Plan" shall mean this Employee Stock Purchase Plan.

         n. "Purchase Period" shall mean, with respect to an Extended Offering
Period, the approximately six (6) month period commencing after one Exercise
Date and ending with the next Exercise Date, except that the first Purchase
Period of any extended Offering Period shall commence on the Enrollment Date and
end with the next Exercise Date. The duration, commencement and termination of
Purchase Periods may be changed pursuant to Section 4 of this Plan.

         o. "Purchase Price" shall mean an amount equal to eighty-five percent
(85%) of the Fair Market Value of a share of Common Stock on the Enrollment Date
or on the Exercise Date, whichever is lower.

         p. "Reserves" shall mean the number of shares of Common Stock covered
by each option under the Plan which have not yet been exercised and the number
of shares of Common Stock which have been authorized for issuance under the Plan
but not yet placed under option.

         q. "Subsidiary" shall mean a corporation, domestic or foreign, of which
not less than fifty percent (50%) of the voting shares are held by the Company
or Subsidiary, whether or not such corporation now exists or is hereafter
organized or acquired by the Company or a Subsidiary.

         r. "Trading Day" shall mean a day on which national stock exchanges and
the NASDAQ system are open for trading.

3.       Eligibility.

         a. Any Employee (as defined in Section 2 (g)) who has been continuously
employed by the Company for at least three (3) months and who is employed by the
Company on a given Enrollment Date shall be eligible to participate in the Plan;
provided, however, that in the case of individuals who become Employees of the
Company as a result of a merger or acquisition, the 



<PAGE>   4

Employee's employment service with the acquired company shall be considered when
determining whether the Employee has met the requirement of three (3) months of
continuous employment.

         b. Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent,
immediately after such grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of the capital stock of the Company, or of
any Subsidiary, or (ii) to the extent his or her rights to purchase stock under
all employee stock purchase plans of the Company and its subsidiaries to accrue
at a rate which exceeds twenty-five thousand dollars ($25,000) worth of stock
(determined at the Fair Market Value of the shares at the time such option is
granted) for each calendar year in which such option is outstanding at any time.

4.        Offering Periods. The Plan shall be implemented by consecutive
Offering Periods with a new Offering Period commencing on the first Trading Day
on or after February 1 and August 1 each year, or on such other dates as the
Board shall determine, and continuing thereafter until terminated in accordance
with Section 19 hereof. The Board shall have the power: (i) to change the
duration, commencement and termination of Offering Periods and/or Purchase
Periods with respect to future offerings without stockholder approval if such
change is announced at least ten (10) days prior to the scheduled beginning of
the first Offering Period or Purchase Period to be effective thereafter, (ii) to
implement Extended Offering Periods, and (iii) to implement overlapping Offering
Periods and/or overlapping Extended Offering Periods.

5.       Participation.

         a. An eligible Employee may become a participant in the Plan by
completing a Subscription Agreement authorizing payroll deductions and filing it
with the Company's Human Resources department at least one (1) day prior to the
applicable Enrollment Date.

         b. Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

6.       Payroll Deductions.

         a. At the time a participant files his or her Subscription Agreement,
he or she shall elect to have payroll deductions made on each pay day during the


<PAGE>   5

Offering Period or Extended Offering Period in an amount not less than one
percent (1%) and not exceeding ten percent (10%) of the Compensation which he or
she receives on each pay day during the Offering Period or Extended Offering
Period, and the aggregate of such payroll deductions during the Offering Period
or Extended Offering Period shall not exceed ten percent (10%) of the
participant's Compensation during said Offering Period or Extended Offering
Period.

         b. All payroll deductions made for a participant shall be credited to
his or her account under the Plan and will be withheld in whole percentages
only. A participant may not make any additional payments into such account.

         c. A participant may discontinue his or her participation in the Plan
as provided in Section 19 hereof by filing with the Company a Notice of
Withdrawal. A participant may increase or decrease the rate of his or her
payroll deductions during the Offering Period by completing or filing with the
Company a Change Form authorizing a change in payroll deduction rate. A
participant may not change his or her payroll deduction rate, either by
increasing or decreasing such rate, more than once during an Offering Period.
The Board may, in its discretion, adjust the number of participation rate
changes permitted during any Offering Period or Purchase Period. The change in
rate shall be effective with the first full payroll period following ten (10)
business days after the Company's receipt of a signed Change Form unless the
Company elects to process a given change in participation more quickly. A
participant's Subscription Agreement shall remain in effect for successive
Offering Periods and Purchase Periods unless terminated as provided in Section
10 hereof.

         d. Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at such time during any
Offering Period or Purchase Period which is scheduled to end during the current
calendar year (the "Current Period") that the aggregate of all payroll
deductions which were previously used to purchase stock under the Plan in a
prior Offering Period or Purchase Period which ended during that calendar year
plus all payroll deductions shall recommence at the rate provided in such
participant's Subscription Agreement at the beginning of the first Offering
Period or Purchase Period which is scheduled to end in the following calendar
year, unless terminated by the participant as provided in Section 10 hereof.

         e. At the time the option is exercised, in whole or in part, or at the
time some or all of the Company's Common Stock issued under the Plan is disposed
of, the participant must make adequate provision for the Company's federal,
state, or other tax withholding obligations, if any, which arise upon the
exercise of the option or the disposition of the Common Stock. At any time, the
Company may, but will not be obligated to, withhold from the participant's
Compensation the amount necessary for the Company to meet applicable withholding
obligations, 


<PAGE>   6

including any withholding required to make available to the Company any tax
deductions or benefits attributable to sale or early disposition of Common Stock
by the Employee.

7.       Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on the Exercise Date of such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the participant's account as of the
Exercise Date by the applicable Purchase Price: provided that in no event shall
an Employee be permitted to purchase during each Offering Period (or, with
respect to an Extended Offering Period, during each six-month Purchase Period)
more than a number of Shares determined by dividing $12,500 by the Fair Market
Value of a share of the Company's Common Stock on the Enrollment Date, and
provided further that such purchase shall be subject to the limitations set
forth in Sections 3(b) and 12 hereof. Exercise of the option shall occur as
provided in Section 8 hereof, unless the participant has withdrawn pursuant to
Section 10 hereof, and shall expire on the last day of the Offering Period.

8.       Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares will
be exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares will be purchased: any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Offering Period or Purchase Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

9.       Delivery. As promptly as practicable after each Exercise Date on which
a purchase of shares occurs, the Company shall arrange the delivery to each
participant, as appropriate, of a certificate representing the shares purchased
upon exercise of his or her option.

10.      Withdrawal and Termination of Employment.

         a. A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company by
completing a Withdrawal Notice available from the Human Resources department.
All of the participant's payroll deductions credited to his or her account will
be paid 


<PAGE>   7
to such participant promptly after receipt of notice of withdrawal and such
participant's option for the Offering Period will be automatically terminated,
and no further payroll deductions for the purchase of shares will be made for
such Offering Period. If a participant withdraws from an Offering Period,
payroll deductions will not resume at the beginning of the succeeding Offering
Period unless the participant delivers to the Company a new Subscription
Agreement.

         b. Upon a participant's ceasing to be an Employee (as defined in
Section 2(g) hereof), for any reason, including by virtue of him or her having
failed to remain an Employee of the Company for at least twenty (20) hours per
week during an Offering Period in which the Employee is a participant, he or she
will be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option will be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 14 hereof, and such participant's option will be automatically
terminated.

11.      Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

12.      Stock.

         a. The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 600,000 including
200,000 shares increase for the fiscal year 2000, subject to adjustment upon
changes in capitalization of the Company as provided for in Section 18 hereof.
Such maximum number of shares shall be increased automatically by 200,000 shares
on the first day of the fiscal year of the Company for fiscal year 2001 and by
150,000 shares on the first day of first year 2002. If on a given Exercise Date
the number of shares with respect to which options are to be exercised exceeds
the number of shares then available under the Plan, the Company shall make a pro
rata allocation of the shares remaining available for purchase in as uniform a
manner as shall be practicable and as it shall determine to be equitable.

         b. The participant will have no interest or voting right in shares
covered by his or her option until such option has been exercised.

         c. Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant and
his or her spouse.

13.      Administration.

         a. Administrative Body. The Plan shall be administered by the Board or
a committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination 


<PAGE>   8

made by the Board or its committee shall, to the full extent permitted by law,
be final and binding upon all parties. Members of the Board who are eligible
employees are permitted to participate in the Plan, provided that:

                  1. Members of the Board who are eligible to participate in the
Plan may not vote on any matter affecting the administration of the Plan or the
grant of any option pursuant to the Plan.

                  2. If a committee is established to administer the Plan, no
member of the Board who is eligible to participate in the Plan may be a member
of the committee.

         b. Rule 16b-3 Limitations. Notwithstanding the provisions of Subsection
(a) of this Section 13, in the event that Rule 16b-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any
successor provision ("Rule 16b-3") provides specific requirements for the
administrators of plans of this type, the Plan shall be only administered by
such a body and such a manner as shall comply with the applicable requirements
of Rule 16b-3. Unless permitted by Rule 16b-3, no discretion concerning
decisions regarding the Plan shall be afforded to any committee or person that
is not "disinterested" as that term is used in Rule 16b-3.

14.      Designation of Beneficiary.

         a. A participant may file a written designation of a beneficiary who is
to receive any shares and cash, if any, from the participant's account under the
Plan in the event of such participant's death subsequent to an Exercise Date on
which the option is exercised but prior to delivery to such participant of such
shares and cash. In addition, a participant may file a written designation of a
beneficiary who is to receive any cash from the participant's account under the
Plan in the event of such participant's death prior to exercise of the option.
If a participant is married and the designated beneficiary is not the spouse,
spousal consent shall be required for such designation to be effective.

         b. Such designation of beneficiary may be changed by the participant at
any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the company may designate.


<PAGE>   9
 15.       Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

16.       Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

17.       Reports. Individual accounts will be maintained for each participant
in the Plan. Statements of account will be given to participating Employees at
least annually, which statements will set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

18.       Adjustments Upon Changes in Capitalization.

         a. Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves as well as the price per share of
Common Stock covered by each option under the Plan which has not been exercised
shall be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock resulting from a stock split, reverse split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of 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 of price of shares of Common Stock subject to an option.

         b. Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company, the Offering Period will terminate immediately
prior to the consummation of such proposed action, unless otherwise provided by
the Board.

         c. Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company,
with or into another corporation, each option under the Plan shall be assumed or
an 


<PAGE>   10

equivalent option shall be substituted by such successor corporation or a parent
or subsidiary of such successor corporation, unless the Board determines, in the
exercise of its sole discretion and in lieu of such assumption or substitution,
to shorten the Offering Period or Extended Offering Period(s) then in progress
by setting a new Exercise Date (the "New Exercise Date") or to cancel each
outstanding right to purchase and refund all sums collected from participants
during the Offering Period(s) or Extended Offering Period(s) then in progress.
If the Board shortens the Offering Period(s) or Extended Offering Period(s) then
in progress in lieu of assumption or substitution in the event of a merger or
sale of assets, the Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
his or her option has been changed to the New Exercise Date and that his or her
option will be exercised automatically on the New Exercise Date, unless prior to
such date he or she has withdrawn from the Offering Period(s) or Extended
Offering Period(s) as provided in Section 10 hereof. For purposes of this
paragraph, an option granted under the Plan shall be deemed to be assumed if,
following the sale of the assets or merger, the option confers the right to
purchase, for each share of option stock subject to the option immediately prior
to the sale of assets or merger, the consideration (whether stock, cash or other
securities or property) received in the sale of assets or merger by holders of
Common Stock for each share of Common Stock held on the effective date of the
transaction (and if such holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
shares of Common Stock); provided, however, that if such consideration received
in the sale of assets or merger was not solely common stock of the successor
corporation or its parent (as defined in Section 424(e) of the Code), the Board
may, with the consent of the successor corporation and the participant, provide
for the consideration to be received upon exercise of the option 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 and the
sale of assets or merger.

         The Board may, if it so determines in the exercise of it discretion,
also make provision for adjusting the Reserves, as well as the price per share
of Common Stock covered by each outstanding option, in the event the Company
effects one or more reorganizations, recapitalization, rights offerings or other
increases or reductions of shares of outstanding Common Stock, and in the event
of the Company being consolidated with or merged into any other corporation.

19.      Amendment or Termination.

         a. The Board may at any time and for any reason terminate or amend the
Plan. Except as provided in Section 18 hereof, no such termination can affect
options previously granted, provided than an Offering Period may be terminated
by the Board on any Exercise Date if the Board determines that the termination
of the Plan is in the best interests of the Company and its stockholders. Except
as 


<PAGE>   11

provided in Section 18 hereof, no amendment may make any change in any option
theretofore granted which adversely affects the rights of the participant. To
the extent necessary to comply with Rule 16b-3 or under Section 423 of the Code
(or any successor rule or provision or any other applicable law or regulation),
the Company shall obtain stockholder approval in such a manner and to such a
degree as required.

         b. Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods,
Extended Offering Periods or Purchase Periods, limit the frequency and/or number
of changes in the amount withheld during an Offering Period, Extended Offering
Period or Purchase Period, establish the exchange ratio applicable to amounts
withheld in a currency other than U.S. dollars, permit payroll withholding in
excess of the amount designated by a participant in order to adjust for delays
or mistakes in the Company's processing of properly completed withholding
elections, establish reasonable waiting and adjustment periods and/or accounting
and crediting procedures to ensure that amounts applied toward the purchase of
Common Stock for each participant properly correspond with amounts withheld from
the participant's Compensation, and establish such other limitations or
procedures as the Board (or its committee) determines in its sole discretion
advisable which are consistent with the Plan.

20.       Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

21.       Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, 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.

         As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of such
exercise that the shares are being purchased 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 by any of the
aforementioned applicable provisions of law.

22.       Term of Plan. The Plan shall become effective upon the earlier to
occur of


<PAGE>   12

its adoption by the Board or its approval by the stockholders of the Company. It
shall continue in effect for a term of ten (10) years unless sooner terminated
in Section 19 hereof.

23.       Additional Restrictions of Rule 16b-3. The terms and conditions of
options granted hereunder to, and the purchase of shares by, persons subject to
Section 16 of the Exchange Act shall comply with the applicable provisions Rule
16b-3. The Plan shall be deemed to contain, and such options shall contain, and
the shares issued upon exercise thereof shall be subject to, such additional
conditions and restrictions as may be required by Rule 16b-3 to qualify for the
maximum exemptions from Section 16 of the Exchange Act with respect to Plan
transactions.

24.       Automatic Transfer to Low Price Extended Offering Period. To the
extent permitted by Rule 16b-3 of the Exchange Act, if the Fair Market Value of
the Common Stock on any Exercise Date in an Extended Offering Period is lower
than the Fair Market Value of the Common Stock on the Enrollment Date of such
Extended Offering Period, then all participants in such Extended Offering Period
shall be automatically withdraw from such Extended Offering Period immediately
after the exercise of their option on such Exercise Date and automatically
reenrolled in the immediately following Extended Offering Period as of the first
day thereof.

25.       Federal Income Tax Implications. The federal income tax consequences
of the grant and exercise of stock options under the Plan, the subsequent
disposition of shares acquired under such options, are summarized below. The
summary is not intended to be exhaustive and may not cover all tax aspects of
every situation. Participants should consult with their tax advisors when
specific questions arise.

         a. Time of Grant of Stock Option. A participant is not taxed at the
time of the grant of his/her stock option even though the Purchase Price is no
greater than eighty-five percent (85%) of the market price of the stock on the
date of the grant.

         b. Time of Exercise of Stock Option. A participant is not taxed when
shares are purchased pursuant to the exercise of an option under the Plan, even
though the shares are purchased at the lower of eighty-five percent (85%) of the
Fair Market Value on the Enrollment Date or eighty-five percent (85%) of the
Fair Market Value on the Exercise Date.

         c. Sale or Other Disposition of Shares Acquired Under the Plan.

                  1. If a participant sells shares after the expiration of two
years or more from the beginning of an Offering Period AND one year or more from
the Exercise Date (the "Statutory Holding Period"):


<PAGE>   13

                           a. Any profit up to the 15% discount on the
Purchase Price (15% of the lesser of the Fair Market Value of the shares at the
beginning of the Offering Period or the Fair Market Value of the shares on the
Exercise Date) is taxable as ordinary income, any further profit is taxable as
gain; and

                           b. Any loss is treated as capital loss.

                  2. If a participant sells or otherwise disposes of shares
before the expiration of the Statutory Holding Periods:

                           a. The difference between the price paid by the
participant and the Fair Market Value of the shares on the date of purchase is
taxable as ordinary income; and

                           b. The difference between the amount received by
the participant on the disposition of the shares and the Fair Market Value of
the shares on the date of purchase is treated as a capital gain or loss.

         d. Tax Deduction by Company. If shares are sold before the expiration
of the Statutory Holding Period, the Company is entitled to a tax deduction for
the difference between the price paid by the participant and the Fair Market
Value of the shares at the date of purchase. At any time, the Company may, but
will not be obligated to, withhold from the participant's Compensation the
amount necessary for the Company to meet applicable withholding obligations,
including any withholding required to make available to the Company any tax
deductions or benefits attributable to sale or early disposition of stock by the
participant.

Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

        7. Term of Plan. The Plan shall become effective upon its adoption by

years from the date 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.

               (b) Waiting Period and Exercise Dates. At the time an Option is

Option may be exercised subject to the limitation contained in Section 8 above.

acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may 




                                      -5-
<PAGE>   6

consist entirely of:

                       (i)   cash;

                       (ii)  check;

                       (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) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;

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

                       (viii) any combination of the foregoing methods of
payment.

        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.

               Unless the Administrator provides otherwise, vesting of Options
granted hereunder shall be tolled during any unpaid leave of absence. An Option
may not be exercised for a fraction of a Share.

                       An Option shall be deemed exercised when the Company 
receives: (i) written or electronic 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 



                                      -6-
<PAGE>   7

the Shares are 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 or transferred) such Shares 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 Shares are
issued, except as provided in Section 12 of the Plan.

                       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 subject to any appropriate adjustment provided by Section 12.

               (b) Withholding. If the gain realized by the Optionee in
connection with the exercise of an Option gives rise to a liability of any
person under the United Kingdom's Pay As You Earn system ("PAYE"), or other
similar withholding tax system, the Company or such other person shall be
entitled to withhold from Optionee's compensation or collect from Optionee and
pay to the applicable taxing authorities an amount in cash equal to its
obligations under PAYE or such other withholding system. The Company may refuse
to honor the exercise and refuse to deliver the Shares if such obligations are
not provided for by the Optionee at the time of exercise. Subject to the
discretion of the Administrator, the Optionee's PAYE obligation and provision
therefor by Optionee may be satisfied by the Optionee electing to have the
Company withhold from the Shares to be issued upon exercise of an Option that
number of Shares having a Fair Market Value equal to the amount required to be
paid to the Inland Revenue of the United Kingdom plus any commission or similar
costs associated with or incurred by the realization of such Shares to fund the
tax liability. The Fair Market Value of the Shares to be withheld shall be
determined on the date that the amount of tax to be withheld is to be
determined. All elections by an Optionee to have Shares withheld for this
purpose shall be made in such form and under such conditions as the
Administrator may deem necessary and advisable.

               (c) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, 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 Option Agreement, and, unless determined
otherwise by the Administrator, only to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term
of such Option as set forth in the Option Agreement). In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for
three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall, unless determined
otherwise by the Administrator, revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified in the
Agreement (or, if none, within three months after termination), the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.



                                      -7-
<PAGE>   8

               (d) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option
Agreement, and, unless determined otherwise by the Administrator, only to the
extent the Option is vested on the date of termination (but in no event later
than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall, unless determined otherwise by the Administrator, 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.

               (e) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant) but only to the extent that
the Option is vested on the date of death, unless determined otherwise by the
Administrator. In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall, unless determined otherwise by the Administrator, immediately revert to
the Plan. The Option may be exercised by the executor or administrator of the
Optionee's estate or, if none, by the person(s) entitled to exercise the Option
under the Optionee's will or the laws of intestacy and succession. If the Option
is not so exercised within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

               (f) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

        11. Non-Transferability of Options . Unless determined otherwise by the
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
intestacy and succession and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12. 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 the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon 



                                      -8-
<PAGE>   9

cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding Option, 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.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

               (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 shall be assumed or an equivalent option
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. In the event that the successor corporation refuses to
assume or substitute for the Option, the Optionee shall fully vest in and have
the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period. For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option confers the right to purchase or receive,
for each Share of Optioned Stock, 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 is 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 



                                      -9-
<PAGE>   10

exercise of the Option, for each Share of Optioned Stock 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.

        13. Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, 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.

        14. Amendment and Termination of the Plan.

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

               (b) 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.

        15. Conditions Upon Issuance of Shares.

               (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws 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 the Company may require the person exercising such Option 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.

        16. 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.

        17. 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.

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 14(b) 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.

        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.

               (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 completed
by the Optionee and delivered to the Secretary 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 Applicable Laws. 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.

        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;



                                      -2-
<PAGE>   13

               (b)     check;

               (c) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan; or

               (d) surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, AND (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

        4. Non-Transferability of Option. Unless determined otherwise by the
Administrator, this Option may not be transferred in any manner other than by
will or by the laws of intestacy and succession 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 United Kingdom ("U.K.") 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 may incur a U.K. income
tax liability upon exercise of his or her option. The Optionee will be treated
as having realized a gain 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. In general, the gain realized by Optionee in connection with the Option
will be subject to the U.K.'s Pay As You Earn system of withholding. The Company
may be required to withhold from Optionee's compensation or collect from
Optionee or from the proceeds and sale of exercised shares and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
gain at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered or satisfied in
accordance with the Plan at the time of exercise.

               (b) Disposition of Shares. Upon subsequent disposition of Shares,
the difference between the sales proceeds and the exercise price (as increased
by an indexation allowance for inflation) will be taxed as capital gains.



                                      -3-

        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 the internal substantive laws, but not
the choice of law rules, of the United Kingdom.

        8. NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND AGREES
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES
HEREUNDER). OPTIONEE 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 A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.

        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.

                                October 23, 1998



Geoworks Corporation
960 Atlantic Avenue
Alameda, CA  94501

Ladies & Gentlemen:

     At your request, we have examined the Registration Statement on Form S-8
(the "Registration Statement") to be filed by you with the Securities and
Exchange Commission (the "Commission") on or about October 23, 1998 in
connection with the registration under the Securities Act of 1933, as amended,
of an aggregate of 1,485,000 additional shares of your Common Stock (the "Common
Stock") subject to issuance by you pursuant to your 1994 Stock Plan, as amended,
the Employee Stock Purchase Plan, as amended and the 1997 Supplemental Stock
Plan, as amended (the "Plans").

     In rendering this opinion, we have examined the following:

     (1)  your Registration Statement on Form 8-A (File No. 0-23926) filed with
          the Commission on April 23, 1994, together with the order of
          effectiveness issued by the Commission therefor on June 22, 1994;

     (2)  the Registration Statement, together with the Exhibits to be filed as
          a part thereof, including without limitation your Certificate of
          Incorporation and Bylaws and the Plans;

     (3)  the Prospectus originally prepared in connection with the Plans and
          with the Registration Statement, as amended to take into account the
          amendment of the Plans increasing by 1,485,000 shares in the number of
          shares of Common Stock subject thereto;

     (4)  the minutes of meetings and actions by written consent of your
          stockholders and Board of Directors relating to the Plans that are
          contained in your minute books and the minute books of your
          predecessor, Geoworks, a California corporation ("Geoworks
          California") that are in our possession;

     (5)  the stock records for both you and Geoworks California that you have
          provided to us (consisting of a list of stockholders prepared by your
          transfer agent, Chase Mellon Shareholder Services, and a list of
          option holders respecting your capital stock that was prepared by
          you); and

     (6)  a Management Certificate addressed to us and dated of even date
          herewith executed by the Company containing certain factual and other
          representations.

     In our examination of documents for purposes of this opinion, we have
assumed, and express no opinion as to, the genuineness of all signatures on
original documents, the authenticity of all documents submitted to us as
originals, the legal capacity of all natural persons executing the same, the
conformity to originals of all documents submitted to us as copies, the 

<PAGE>   2

lack of any undisclosed terminations, modifications, waivers or amendments to
any documents reviewed by us and the due execution and delivery of all documents
where due execution and delivery are prerequisites to the effectiveness thereof.

     As to matters of fact relevant to this opinion, we have relied solely upon
our examination of the documents referred to above and have assumed the current
accuracy and completeness of the information and records included in the
documents referred to above. We have made no independent investigation or other
attempt to verify the accuracy of any of such information or to determine the
existence or non-existence of any other factual matters; however, we are not
aware of any facts that would lead us to believe that the opinion expressed
herein is not accurate. Our opinion below is given on the assumption that shares
of Common Stock may not be issued and sold by you in accordance with the Plans
or the Assumed Options unless and until such shares, at the time in question,
are explicitly reserved and available for issuance under the Plans.

     We are admitted to practice law in the State of California, and we express
no opinion herein with respect to the application or effect of the laws of any
jurisdiction other than the existing laws of the United States of America and
the State of California and (without reference to case law or secondary sources)
the existing Delaware General Corporation Law.

     Based upon the foregoing, it is our opinion that the 1,485,000 additional
shares of Common Stock that may be issued and sold by you pursuant to the Plans,
when issued and sold in accordance with the Plans and in the manner referred to
in the Prospectus associated with the Plans and the Registration Statement, will
be validly issued, fully paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us, if any, in the
Registration Statement, the Prospectus constituting a part thereof and any
amendments thereto.

     This opinion speaks only as of its date and is intended solely for your use
as an exhibit to the Registration Statement for the purpose of the above sale of
the Common Stock and is not to be relied upon for any other purpose.

                                       Very truly yours,


                                       FENWICK & WEST LLP

               CONSENT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
