    1.     PURPOSES OF THE PLAN.  The purposes of this Stock Plan are:

           -     to attract and retain the best available personnel for

           -     to provide additional incentive to Employees and Consultants,
                 and

           -     to promote the success of the Company's business.


Options granted under the Plan may be Incentive Stock Options or Nonstatutory 
Stock Options, as determined by the Administrator at the time of grant.  
Stock Purchase Rights may also be granted under the Plan.

under the Plan (unless the Plan has terminated); PROVIDED,

the Plan, except that if Shares of Restricted Stock are repurchased by 
the Company at their original purchase price, and the original 
purchaser of such Shares did not receive any benefits of ownership of 
such Shares, such Shares shall become available for future grant under 
the Plan.  For purposes of the preceding sentence, voting rights shall 
not be considered a benefit of Share ownership.

    4.     ADMINISTRATION OF THE PLAN.

           (a)  PROCEDURE.

                   (i)  MULTIPLE ADMINISTRATIVE BODIES.  If permitted by Rule 
16b-3, the Plan may be administered by different bodies with respect to 
Directors, Officers who are not Directors, and Employees who are 
neither Directors nor Officers.

                   (ii)  ADMINISTRATION WITH RESPECT TO DIRECTORS AND OFFICERS 
SUBJECT TO SECTION 16(b).  With respect to Option or Stock Purchase 
Right grants made to Employees who are also Officers or Directors 
subject to Section 16(b) of the Exchange Act, the Plan shall be 
administered by (A) the Board, if the Board may administer the Plan in 
a manner complying with the rules under Rule


                                      55



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

                   (iii)  ADMINISTRATION WITH RESPECT TO OTHER PERSONS.  
With respect to Option or Stock Purchase Right grants made to Employees or 
Consultants who are 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 to satisfy Applicable Laws.  Once 
appointed, such Committee shall serve in its designated capacity until 
otherwise directed by the Board.  The Board may increase the size of the 
Committee and appoint additional members, remove members (with or without 
cause) and substitute new members, fill vacancies (however caused), and 
remove all members of the Committee and thereafter directly administer the 
Plan, all to the extent permitted by Applicable Laws.

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

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

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

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

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

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

                   (vi)  to determine the terms and conditions, not 
inconsistent with the terms of the Plan, of any award granted hereunder.  
Such terms and conditions include, but are not limited to, the


                                      56



exercise price, the time or times when Options or Stock Purchase 
Rights may be exercised (which may be based on performance criteria), 
any vesting acceleration or waiver of forfeiture restrictions, and any 
restriction or limitation regarding any Option of Stock Purchase Right 
or the shares of Common Stock relating thereto, based in each case on 
such factors as the Administrator, in its sole discretion, shall 
determine;

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

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

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

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

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

                   (xii)  to institute an Option Exchange Program;

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

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

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

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


                                        57


    6.     LIMITATIONS.

           (a)  Each Option shall be designated in the written option agreement 
as either an Incentive Stock Option or a Nonstatutory Stock Option.  However, 
notwithstanding such designation, to the extent that the aggregate Fair 
Market Value of the Shares with respect to which Incentive Stock Options are 
exercisable for the first time by the Optionee during any calendar year 
(under all plans of the Company and any Parent or Subsidiary) exceeds 
$100,000, such Options shall be treated as Nonstatutory Stock Options.  For 
purposes of this Section 6(a) Incentive Stock Options shall be taken into 
account in the order in which they were granted.  The Fair Market Value of 
the Shares shall be determined as of the time the Option with respect to such 
Shares is granted.

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

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

                   (i)  No Employee shall be granted, in any fiscal year of 
the Company, Options and Stock Purchase Rights to purchase  more than 
250,000 Shares.

                   (ii)  In connection with his or her initial employment, an 
Employee may be granted Options and Stock Purchase Rights to purchase up to 
an additional 250,000 Shares which shall not count against the limit set 
forth in subsection (i) above.

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

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

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

    8.     TERM OF OPTION.  The term of each Option shall be stated in the 
Notice of Grant; provided, however, that in the case of an Incentive Stock 
Option, the term shall be ten (10) years


                                      58


from the date of grant or such shorter term as may be provided in the Notice 
of Grant. Moreover, in the case of an incentive Stock Option granted to an 
Optionee who, at the time the incentive Stock Option is granted, owns stock 
representing more than ten percent (10%) of the voting power of all classes 
of stock of the Company or any Parent or Subsidiary, the term of the 
Incentive Stock Option shall be five (5) years from the date of grant or such 
shorter term as may be provided in the Notice of Grant.

    9.     OPTION EXERCISE PRICE AND CONSIDERATION.

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

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

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

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

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

                   (i)   cash;

                   (ii)  check; 

                   (iii) promissory note;


                                       59



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

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

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

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

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

    10.    EXERCISE OF OPTION.

           (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.  Any Option 
granted hereunder shall be exercisable according to the terms of the Plan and 
at such times and under such conditions as determined by the Administrator 
and set forth in the Option Agreement.

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

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


                                       60



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

           (b)  TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP.  Upon 
termination of an Optionee's Continuous Status as an Employee or Consultant, 
other than upon the Optionee's death or Disability, the Optionee may exercise 
his or her Option, but only within such period of time as is specified in the 
Notice of Grant, and only to the extent that the Optionee was entitled to 
exercise it at the date of termination (but in no event later than the 
expiration of the term of such Option as set forth in the Notice of Grant). 
In the absence of a specified time in the Notice of Grant, the Option shall 
remain exercisable for three (3) months following the Optionee's termination. 
In the case of an Incentive Stock Option, such period of time for exercise 
shall not exceed three (3) months from the date of termination. If, on the 
date of termination, the Optionee is not entitled to exercise the Optionee's 
entire Option, the Shares covered by the unexercisable portion of the 
Option shall revert to the Plan. If, after termination, the Optionee does 
not exercise his or her Option within the time specified by the 
Administrator, the Option shall terminate, and the Shares covered by such 
Option shall revert to the Plan.

           Notwithstanding the above, in the event of an Optionee's change in 
status from Consultant to Employee or Employee to Consultant, an Optionee's 
Continuous Status as an Employee or Consultant shall not automatically 
terminate solely as a result of such change in status. However, in such 
event, an Incentive Stock Option held by the Optionee shall cease to be 
treated as an Incentive Stock Option and shall be treated for tax purposes as 
a Nonstatutory Stock Option three months and one day following such change of 
status.

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

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


                                       61



does not exercise the Option within the time specified herein, the Option 
shall terminate, and the Shares covered by such Option shall revert to the 
Plan.

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

    11.    STOCK PURCHASE RIGHTS. 

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

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

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

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

           (e)  RIGHTS AS A SHAREHOLDER.  Once the Stock Purchase Right is 
exercised, the purchaser shall have the rights equivalent to those of a 
shareholder, and shall be a shareholder when his or her purchase is entered 
upon the records of the duly authorized transfer agent of the Company.


                                      62


No adjustment will be made for a dividend or other right for which the record 
date is prior to the date the Stock Purchase Right is exercised, except as 
provided in Section 13 of the Plan.

    12.    NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS.  An 
Option or Stock Purchase Right may not be sold, pledged, assigned, 
hypothecated, transferred, or disposed of in any manner other than by will or 
by the laws of descent or distribution and may be exercised, during the 
lifetime of the Optionee, only by the Optionee.

    13.    ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR 
ASSET SALE.

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

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

           (c)  MERGER OR ASSET SALE.  In the event of a merger of the Company 
with or into another corporation, or the sale of substantially all of the 
assets of the Company, each outstanding Option and Stock Purchase Right shall 
be assumed or an equivalent option or right 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 or Stock Purchase Right, the Optionee shall have the right to exercise 
the Option or Stock Purchase Right as to all of the Optioned Stock, including 
Shares as to which it would not otherwise be exercisable. If an Option or 
Stock


                                      63


Purchase Right is exercisable in lieu of assumption or substitution in the 
event of a merger or sale of assets, the Administrator shall notify the 
Optionee that the Option or Stock Purchase Right shall be fully exercisable 
for a period of fifteen (15) days from the date of such notice, and the 
Option or Stock Purchase Right shall terminate upon the expiration of such 
period. For the purposes of this paragraph, the Option or Stock Purchase 
Right shall be considered assumed if, following the merger or sale of assets, 
the option or right confers the right to purchase or receive, for each Share 
of Optioned Stock subject to the Option or Stock Purchase Right immediately 
prior to the merger or sale of assets, the consideration (whether stock, 
cash, or other securities or property) received in the merger or sale of 
assets by holders of Common Stock for each Share held on the effective date 
of the transaction (and if holders were offered a choice of consideration, 
the type of consideration chosen by the holders of a majority of the 
outstanding Shares); provided, however, that if such consideration received 
in the merger or sale of assets was not solely common stock of the successor  
corporation or its Parent, the Administrator may, with the consent of the 
successor corporation, provide for the consideration to be received upon the 
exercise of the Option or Stock Purchase Right, for each Share of Optioned 
Stock subject to the Option or Stock Purchase Right, to be solely common 
stock of the successor corporation or its Parent equal in fair market value 
to the per share consideration received by holders of Common Stock in the 
merger or sale of assets.

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

    15.    AMENDMENT AND TERMINATION OF THE PLAN.

           (a)  AMENDMENT AND TERMINATION. The Board may at any time amend, 
alter, suspend or terminate the Plan.

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

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


                                      64


    16.    CONDITIONS UPON ISSUANCE OF SHARES.

           (a)  LEGAL COMPLIANCE.  Shares shall not be issued pursuant to the 
exercise of an Option or Stock Purchase Right unless the exercise of such 
Option or Stock Purchase Right and the issuance and delivery of such Shares 
shall comply with all relevant provisions of law, including, without 
limitation, the Securities Act of 1933, as amended, the Exchange Act, the 
rules and regulations promulgated thereunder, Applicable Laws, and the 
requirements of any stock exchange or quotation system upon which the Shares 
may then be listed or quoted, and shall be further subject to the approval of 
counsel for the Company with respect to such compliance.

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

    17.    LIABILITY OF COMPANY. 

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

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

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

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

                                      66


     TERMINATION PERIOD:

     This Option may be exercised for    [days/months] after termination of

the death or Disability of the Optionee, this Option may be exercised for 
such longer period as provided in the Plan. In the event of the Optionee's 
change in status from Employee to Consultant or Consultant to Employee, this 
Option Agreement shall remain in effect. In no event shall this Option be

II. AGREEMENT

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

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

     2.  EXERCISE OF OPTION.

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

         (b)  METHOD OF EXERCISE.  This Option is exercisable by delivery of 
an exercise notice, in the form attached as Exhibit A (the "Exercise 
Notice"), which shall state the election to exercise the Option, the number 
of Shares in respect of which the Option is being exercised (the "Exercised 
Shares"), and such other representations and agreements as may be required by 
the Company pursuant to the provisions of the Plan. The Exercise Notice shall 
be signed by the Optionee and shall be delivered in person or by certified 
mail to the 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.

                                      67

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

     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;

         (b) check;

         (c) delivery of a properly executed exercise notice together with 
such other documentation as the Administrator and the broker, if applicable, 
shall require to effect an exercise of the Option and delivery to the Company 
of the sale or loan proceeds required to pay the exercise price; 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.  This Option may not be transferred 
in any manner otherwise than by will or by the laws of descent or 
distribution and may be exercised during the lifetime of Optionee only by the 
Optionee. The terms of the Plan and this Option Agreement shall be binding 
upon the executors, administrators, heirs, successors and assigns of the 
Optionee.

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

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

         (a) EXERCISING THE OPTION.

              (i)  NONSTATUTORY STOCK OPTION.  The Optionee may incur regular 
federal income tax and California income tax liability upon exercise of a 
NSO. The Optionee will be treated as having received compensation income 
(taxable at ordinary income tax rates) equal to the excess, if


                                       68


any, of the Fair Market Value of the Exercised Shares on the date of exercise 
over their aggregate Exercise Price. If the Optionee is an Employee or a 
former Employee, the Company will be required to withhold from his or her 
compensation or collect from Optionee and pay to the applicable taxing 
authorities an amount in cash equal to a percentage of this compensation 
income at the time of exercise, and refuse to honor the exercise and refuse 
to deliver Shares if such withholding amounts are not delivered at the time 
of exercise.

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

         (b) DISPOSITION OF SHARES.

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

              (ii) ISO. If the Optionee holds ISO Shares for at least one 
year after exercise and two years after the grant date, any gain realized on 
disposition of the Shares will be treated as long-term capital gain for 
federal income tax purposes. If the Optionee disposes of ISO Shares within 
one year after exercise or two years after the grant date, any gain realized 
on such disposition will be treated as compensation income (taxable at 
ordinary income rates) to the extent of the excess, if any, of the lesser of 
(A) the difference between the Fair Market Value of the Shares acquired on 
the date of exercise and the aggregate Exercise Price, or (B) the difference 
between the sale price of such Shares and the aggregate Exercise Price.

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

     7.  ENTIRE AGREEMENT; GOVERNING LAW. The Plan is incorporated herein by 
reference. The Plan and this Option Agreement constitute the entire agreement 
of the parties with respect to the subject matter hereof and supersede in 
their entirety all prior undertakings and agreements of the Company and 
Optionee with respect to the subject matter hereof, and may not be modified 
adversely
