resolutions, not inconsistent with the provisions of the Plan, as may be

Rights exercised in accordance with Section 8 of the Plan shall not be available

    (b)  The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

Stock Options and Stock Appreciation Rights appurtenant thereto may be granted
only to Employees, Directors or Consultants.

Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Option is at least one hundred

and the Option is not exercisable after the expiration of five (5) years from
the date of grant.

    (c)  Subject to the provisions of Section 13 relating to adjustments upon
changes in stock, no person shall be eligible to be granted Options and Stock
Appreciation Rights covering more than two hundred fifty thousand (250,000)
shares of the Company's common stock in any calendar year.

6.  OPTION PROVISIONS.

    Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate.  The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:


                                     5



    (a)  TERM.  No Option shall be exercisable after the expiration of ten (10)
years from the date it was granted.

    (b)  PRICE.  The exercise price of each Incentive Stock Option shall be not
less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted; the exercise price of
each Nonstatutory Stock Option shall be not less than eighty-five percent (85%)
the Fair Market Value of the stock subject to the Option on the date the Option
is granted.  Notwithstanding the foregoing, an Option (whether an Incentive
Stock Option or a Nonstatutory Stock Option) may be granted with an exercise
price lower than that set forth in the preceding sentence if such Option is
granted pursuant to an assumption or substitution for another option in a manner
satisfying the provisions of Section 424(a) of the Code.

    (c)  CONSIDERATION.  The purchase price of stock acquired pursuant to an 
Option shall be paid, to the extent permitted by applicable statutes and 
regulations, either (i) in cash at the time the Option is exercised, or (ii) 
at the discretion of the Board or the Committee, at the time of the grant of 
the Option, (A) by delivery to the Company of other common stock of the 
Company, (B) according to a deferred payment or other arrangement (which may 
include, without limiting the generality of the foregoing, the use of other 
common stock of the Company) with the person to whom the Option is granted or 
to whom the Option is transferred pursuant to subsection 6(d), or (C) in any 
other form of legal consideration acceptable to the Board.  In the case of 
any deferred payment arrangement, interest shall be compounded at least 
annually and shall be charged at the minimum rate of interest necessary to 
avoid the treatment as interest, under any applicable provisions of the Code, 
of any amounts other than amounts stated to be interest under the deferred 
payment arrangement.

    (d)  TRANSFERABILITY.  An Incentive Stock Option shall not be 
transferable except by will or by the laws of descent and distribution, and 
shall be exercisable during the lifetime of the person to whom the Incentive 
Stock Option is granted only by such person.  A Nonstatutory Stock Option 
shall only be transferable by the Optionee upon such terms and conditions as 
are set forth in the Option Agreement for such Nonstatutory Stock Option, as 
the Board or the Committee shall determine in its sole discretion.  The 
person to whom the Option is granted may, by delivering written notice to the 
Company, in a form satisfactory to the Company, designate a third party who, 
in the event of the death of the Optionee, shall thereafter be entitled to 
exercise the Option.

    (e)  VESTING.  The total number of shares of stock subject to an Option
may, but need not, be allotted in periodic installments (which may, but need
not, be equal).  The Option Agreement may provide that from time to time during
each of such installment periods, the Option may become exercisable ("vest")
with respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised.  The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem 


                                     6


appropriate.  The provisions of this subsection 6(e) are subject to any 
Option provisions governing the minimum number of shares as to which an 
Option may be exercised.

    (f)  TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR 
CONSULTANT. In the event an Optionee's Continuous Status as an Employee, 
Director or Consultant terminates (other than upon the Optionee's death or 
disability or for Cause), the Optionee may exercise his or her Option (to the 
extent that the Optionee was entitled to exercise it as of the date of 
termination) but only within such period of time ending on the earlier of (i) 
the date three (3) months following the termination of the Optionee's 
Continuous Status as an Employee, Director or Consultant (or such longer or 
shorter period specified in the Option Agreement), or (ii) the expiration of 
the term of the Option as set forth in the Option Agreement.  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 and again become available for issuance under the Plan.  If, after 
termination, the Optionee does not exercise his or her Option within the time 
specified in the Option Agreement, the Option shall terminate, and the shares 
covered by such Option shall revert to and again become available for 
issuance under the Plan.

    In the event an Optionee's Continuous Status as an Employee, Director or 
Consultant terminates for Cause, then the Option shall immediately terminate, 
and the shares covered by such Option shall revert to and again become 
available for issuance under the Plan.  "Cause" shall be defined as an act of 
embezzlement, fraud, dishonesty, or breach of fiduciary duty to the Company, 
a deliberate disregard of the rules of the Company which results in loss, 
damage or injury to the Company, any unauthorized disclosure of any of the 
secrets or confidential information of the Company, inducing any client or 
customer of the Company to break any contract with the Company or inducing 
any principal for whom the Company acts as agent to terminate such agency 
relations, or engaging in any conduct which constitutes unfair competition 
with the Company, or any act which results in Optionee being removed from any 
office of the Company by any bank regulatory agency.

    An Optionee's Option Agreement may also provide that if the exercise of 
the Option following the termination of the Optionee's Continuous Status as 
an Employee, Director, or Consultant (other than upon the Optionee's death or 
disability) would result in liability under Section 16(b) of the Exchange 
Act, then the Option shall terminate on the earlier of (i) the expiration of 
the term of the Option set forth in the Option Agreement, or (ii) the tenth 
(10th) day after the last date on which such exercise would result in such 
liability under Section 16(b) of the Exchange Act.  Finally, an Optionee's 
Option Agreement may also provide that if the exercise of the Option 
following the termination of the Optionee's Continuous Status as an Employee, 
Director or Consultant (other than upon the Optionee's death or disability) 
would be prohibited at any time solely because the issuance of shares would 
violate the registration requirements under the Securities Act, then the 
Option shall terminate on the earlier of (i) the expiration of the term of 
the Option, or (ii) the expiration of a period of three (3) months after the 
termination of the Optionee's Continuous Status as an Employee, Director or 
Consultant during which the exercise of the Option would not be in violation 
of such registration requirements.


                                     7



    (g)  DISABILITY OF OPTIONEE.  In the event an Optionee's Continuous 
Status as an Employee, Director or Consultant terminates as a result of the 
Optionee's disability, the Optionee may exercise his or her Option (to the 
extent that the Optionee was entitled to exercise it as of the date of 
termination), but only within such period of time ending on the earlier of 
(i) the date twelve (12) months following such termination (or such longer or 
shorter period specified in the Option Agreement), or (ii) the expiration of 
the term of the Option as set forth in the Option Agreement.  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 and again become available for issuance under 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 and again become available for issuance under the Plan.

    (h)  DEATH OF OPTIONEE.  In the event an Optionee's Continuous Status as 
an Employee, Director or Consultant terminates as a result of Optionee's 
death, the Option may be exercised (to the extent the Optionee was entitled 
to exercise the Option as of the date of death) by the Optionee's estate, by 
a person who acquired the right to exercise the Option by bequest or 
inheritance or by a person designated to exercise the option upon the 
Optionee's death pursuant to subsection 6(d), but only within the period 
ending on the earlier of (i) the date twelve (12) months following the date 
of death (or such longer or shorter period specified in the Option 
Agreement), or (ii) the expiration of the term of such Option as set forth in 
the Option Agreement.  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 revert to and again become 
available for issuance under the Plan.  If, after death, the Option is not 
exercised within the time specified herein, the Option shall terminate, and 
the shares covered by such Option shall revert to and again become available 
for issuance under the Plan.

    (i)  EARLY EXERCISE.  The Option may, but need not, include a provision 
whereby the Optionee may elect at any time while an Employee, Director or 
Consultant to exercise the Option as to any part or all of the shares subject 
to the Option prior to the full vesting of the Option.  Any unvested shares 
so purchased may be subject to a repurchase right in favor of the Company or 
to any other restriction the Board determines to be appropriate.

7.  TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

    Each stock bonus or restricted stock purchase agreement shall be in such 
form and shall contain such terms and conditions as the Board or the 
Committee shall deem appropriate.  The terms and conditions of stock bonus or 
restricted stock purchase agreements may change from time to time, and the 
terms and conditions of separate agreements need not be identical, but each 
stock bonus or restricted stock purchase agreement shall include (through 
incorporation of provisions hereof by reference in the agreement or 
otherwise) the substance of each of the following provisions as appropriate:

    (a)  PURCHASE PRICE.  The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such Stock Award Agreement, but in no event shall the
purchase price be less than eighty-five percent 

 
                                     8



(85%) of the stock's Fair Market Value on the date such award is made. 
Notwithstanding the foregoing, the Board or the Committee may determine that 
eligible participants in the Plan may be awarded stock pursuant to a stock 
bonus agreement in consideration for past services actually rendered to the 
Company or for its benefit.

    (b)  TRANSFERABILITY.  Rights under a stock bonus or restricted stock
purchase agreement shall be transferable by the grantee only upon such terms and
conditions as are set forth in the applicable Stock Award Agreement, as the
Board or the Committee shall determine in its discretion, so long as stock
awarded under such Stock Award Agreement remains subject to the terms of the
agreement.

    (c)  CONSIDERATION.  The purchase price of stock acquired pursuant to a
stock purchase agreement shall be paid either:  (i) in cash at the time of
purchase; (ii) at the discretion of the Board or the Committee, according to a
deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the
Board or the Committee in its discretion.  Notwithstanding the foregoing, the
Board or the Committee to which administration of the Plan has been delegated
may award stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit.

    (d)  VESTING.  Shares of stock sold or awarded under the Plan may, but need
not, be subject to a repurchase option in favor of the Company in accordance
with a vesting schedule to be determined by the Board or the Committee.

    (e)  TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR CONSULTANT. 
In the event a Participant's Continuous Status as an Employee, Director or
Consultant terminates, the Company may repurchase or otherwise reacquire any or
all of the shares of stock held by that person which have not vested as of the
date of termination under the terms of the stock bonus or restricted stock
purchase agreement between the Company and such person.

8.  STOCK APPRECIATION RIGHTS.

    (a)  The Board or Committee shall have full power and authority,
exercisable in its sole discretion, to grant Stock Appreciation Rights under the
Plan to Employees or Directors of or Consultants to, the Company or its
Affiliates.  To exercise any outstanding Stock Appreciation Right, the holder
must provide written notice of exercise to the Company in compliance with the
provisions of the Stock Award Agreement evidencing such right.  Except as
provided in subsection 5(c), no limitation shall exist on the aggregate amount
of cash payments the Company may make under the Plan in connection with the
exercise of a Stock Appreciation Right.

    (b)  Three types of Stock Appreciation Rights shall be authorized for
issuance under the Plan:

         (1)  TANDEM STOCK APPRECIATION RIGHTS.  Tandem Stock Appreciation
Rights will be granted appurtenant to an Option, and shall, except as
specifically set forth in this Section 


                                     9



8, be subject to the same terms and conditions applicable to the particular 
Option grant to which it pertains. Tandem Stock Appreciation Rights will 
require the holder to elect between the exercise of the underlying Option for 
shares of stock and the surrender, in whole or in part, of such Option for an 
appreciation distribution.  The appreciation distribution payable on the 
exercised Tandem Right shall be in cash (or, if so provided, in an equivalent 
number of shares of stock based on Fair Market Value on the date of the 
Option surrender) in an amount up to the excess of (A) the Fair Market Value 
(on the date of the Option surrender) of the number of shares of stock 
covered by that portion of the surrendered Option in which the Optionee is 
vested over (B) the aggregate exercise price payable for such vested shares.

         (2)  CONCURRENT STOCK APPRECIATION RIGHTS.  Concurrent Rights will be
granted appurtenant to an Option and may apply to all or any portion of the
shares of stock subject to the underlying Option and shall, except as
specifically set forth in this Section 8, be subject to the same terms and
conditions applicable to the particular Option grant to which it pertains.  A
Concurrent Right shall be exercised automatically at the same time the
underlying Option is exercised with respect to the particular shares of stock to
which the Concurrent Right pertains.  The appreciation distribution payable on
an exercised Concurrent Right shall be in cash (or, if so provided, in an
equivalent number of shares of stock based on Fair Market Value on the date of
the exercise of the Concurrent Right) in an amount equal to such portion as
shall be determined by the Board or the Committee at the time of the grant of
the excess of (A) the aggregate Fair Market Value (on the date of the exercise
of the Concurrent Right) of the vested shares of stock purchased under the
underlying Option which have Concurrent Rights appurtenant to them over (B) the
aggregate exercise price paid for such shares.

         (3)  INDEPENDENT STOCK APPRECIATION RIGHTS.  Independent Rights will 
be granted independently of any Option and shall, except as specifically set 
forth in this Section 8, be subject to the same terms and conditions 
applicable to Nonstatutory Stock Options as set forth in Section 6.  They 
shall be denominated in share equivalents.  The appreciation distribution 
payable on the exercised Independent Right shall be not greater than an 
amount equal to the excess of (A) the aggregate Fair Market Value (on the 
date of the exercise of the Independent Right) of a number of shares of 
Company stock equal to the number of share equivalents in which the holder is 
vested under such Independent Right, and with respect to which the holder is 
exercising the Independent Right on such date, over (B) the aggregate Fair 
Market Value (on the date of the grant of the Independent Right) of such 
number of shares of Company stock.  The appreciation distribution payable on 
the exercised Independent Right shall be in cash or, if so provided, in an 
equivalent number of shares of stock based on Fair Market Value on the date 
of the exercise of the Independent Right.

9.  CANCELLATION AND RE-GRANT OF OPTIONS.

    (a)  The Board or the Committee shall have the authority to effect, at any
time and from time to time,  (i) the repricing of any outstanding Options and/or
any Stock Appreciation Rights under the Plan and/or (ii) with the consent of the
affected holders of Options and/or Stock Appreciation Rights, the cancellation
of any outstanding Options and/or any Stock Appreciation Rights under the Plan
and the grant in substitution therefor of new Options and/or Stock Appreciation
Rights under the Plan covering the same or different numbers of shares of stock,


                                     10



but having an exercise price per share not less than eighty-five percent 
(85%) of the Fair Market Value (one hundred percent (100%) of the Fair Market 
Value in the case of an Incentive Stock Option) or, in the case of a 10% 
shareholder (as described in subsection 5(b)) receiving a new grant of an 
Incentive Stock Option, not less than one hundred ten percent (110%) of the 
Fair Market Value) per share of stock on the new grant date.  Notwithstanding 
the foregoing, the Board or the Committee may grant an Option and/or Stock 
Appreciation Right with an exercise price lower than that set forth above if 
such Option and/or Stock Appreciation Right is granted as part of a 
transaction to which section 424(a) of the Code applies.

    (b)  Shares subject to an Option or Stock Appreciation Right canceled under
this Section 9 shall continue to be counted against the maximum award of Options
and Stock Appreciation Rights permitted to be granted pursuant to subsection
5(c) of the Plan.  The repricing of an Option and/or Stock Appreciation Right
under this Section 9, resulting in a reduction of the exercise price, shall be
deemed to be a cancellation of the original Option and/or Stock Appreciation
Right and the grant of a substitute Option and/or Stock Appreciation Right; in
the event of such repricing, both the original and the substituted Options and
Stock Appreciation Rights shall be counted against the maximum awards of Options
and Stock Appreciation Rights permitted to be granted pursuant to subsection
5(c) of the Plan.  The provisions of this subsection 9(b) shall be applicable
only to the extent required by Section 162(m) of the Code.

10. COVENANTS OF THE COMPANY.

    (a)  During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of stock required to satisfy such Stock
Awards.

    (b)  The Company shall seek to obtain from each regulatory commission or 
agency having jurisdiction over the Plan such authority as may be required to 
issue and sell shares of stock upon exercise of the Stock Award; provided, 
however, that this undertaking shall not require the Company to register 
under the Securities Act either the Plan, any Stock Award or any stock issued 
or issuable pursuant to any such Stock Award.  If, after reasonable efforts, 
the Company is unable to obtain from any such regulatory commission or agency 
the authority which counsel for the Company deems necessary for the lawful 
issuance and sale of stock under the Plan, the Company shall be relieved from 
any liability for failure to issue and sell stock upon exercise of such Stock 
Awards unless and until such authority is obtained.

11. USE OF PROCEEDS FROM STOCK.

    Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.


                                     11



12. MISCELLANEOUS.

    (a)  The Board shall have the power to accelerate the time at which a Stock
Award may first be exercised or the time during which a Stock Award or any part
thereof will vest pursuant to subsection 6(e), 7(d) or 8(b), notwithstanding the
provisions in the Stock Award stating the time at which it may first be
exercised or the time during which it will vest.

    (b)  Neither an Employee, Director or Consultant nor any person to whom a
Stock Award is transferred under subsection 6(d), 7(b), or 8(b) shall be deemed
to be the holder of, or to have any of the rights of a holder with respect to,
any shares subject to such Stock Award unless and until such person has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

    (c)  Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Director, Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or any
Affiliate (or to continue acting as a Director or Consultant) or shall affect
the right of the Company or any Affiliate to terminate the employment of any
Employee with or without cause the right of the Company's Board of Directors
and/or the Company's shareholders to remove any Director as provided in the
Company's Bylaws and the provisions of the California Corporations Code, or the
right to terminate the relationship of any Consultant subject to the terms of
such Consultant's agreement with the Company or Affiliate.

    (d)  To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

    (e)  The Company may require any person to whom a Stock Award is granted,
or any person to whom a Stock Award is transferred pursuant to subsection 6(d),
7(b) or 8(b), as a condition of exercising or acquiring stock under any Stock
Award, (1) to give written assurances satisfactory to the Company as to such
person's knowledge and experience in financial and business matters and/or to
employ a purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (2) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account and
not with any present intention of selling or otherwise distributing the stock. 
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under
a then currently effective registration statement under the Securities Act, or
(ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the


                                     12



then applicable securities laws.  The Company may, upon advice of counsel to 
the Company, place legends on stock certificates issued under the Plan as 
such counsel deems necessary or appropriate in order to comply with 
applicable securities laws, including, but not limited to, legends 
restricting the transfer of the stock.

    (f)  To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under a Stock Award by any of the following means or by a combination of such
means:  (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the common stock otherwise issuable to the participant
as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the common stock
of the Company.

13. ADJUSTMENTS UPON CHANGES IN STOCK.

    (a)  If any change is made in the stock subject to the Plan, or subject 
to any Stock Award (through merger, consolidation, reorganization, 
recapitalization, reincorporation, stock dividend, dividend in property other 
than cash, stock split, liquidating dividend, combination of shares, exchange 
of shares, change in corporate structure or other transaction not involving 
the receipt of consideration by the Company), the Plan will be appropriately 
adjusted in the type(s) and maximum number of securities subject to the Plan 
pursuant to subsection 4(a) and the maximum number of securities subject to 
award to any person during any calendar year pursuant to subsection 5(c), and 
the outstanding Stock Awards will be appropriately adjusted in the type(s) 
and number of securities and price per share of stock subject to such 
outstanding Stock Awards.  Such adjustments shall be made by the Board or the 
Committee, the determination of which shall be final, binding and conclusive. 
(The conversion of any convertible securities of the Company shall not be 
treated as a "transaction not involving the receipt of consideration by the 
Company.)"

    (b)  In the event of "Change in Control," all outstanding Stock Awards
shall immediately become one hundred percent (100%) vested, and the Board shall
notify all participants that their outstanding Stock Awards shall be fully
exercisable for a period of three (3) months (or such other period of time not
exceeding six (6) months as is determined by the Board at the time of grant)
from the date of such notice, and any unexercised Stock Awards shall terminate
upon the expiration of such period.

    "Change in Control" means the occurrence of any of the following events:

         (1)  the shareholders of the Company approve a merger or consolidation
of the Company with any other corporation, other than a merger or consolidation
which would result in beneficial owners of the total voting power in the
election of directors represented by the voting securities ("Voting Securities")
of the Company outstanding immediately prior thereto continuing to beneficially
own securities representing (either by remaining outstanding or by being
converted into voting securities of the surviving entity) more than fifty
percent (50%) of the total 


                                     13


Voting Securities of the Company, or of such surviving entity, outstanding 
immediately after such merger or consolidation;

         (2)  the shareholders of the Company approve a plan of liquidation or
dissolution of the Company or approve an agreement for the sale, lease, exchange
or other transfer or disposition by the Company of all or substantially all of
the Company's assets;

         (3)  any person (as such term is used in Sections 13(d) and 14(d) of
the Exchange Act), other than (A) a trustee or other fiduciary holding
securities under an employee benefit plan of the Company or (B) a corporation
owned directly or indirectly by the shareholders of the Company in substantially
the same proportions as their beneficial ownership of stock in the Company, is
or becomes the beneficial owner (within the meaning of Rule 13d-3 under the
Exchange Act), directly or indirectly, of the securities of the Company
representing fifty percent (50%) or more of the Voting Securities; or

         (4)  (A) (1) the shareholders of the Company approve a merger or 
consolidation of the Company with any other corporation, other than a merger 
or consolidation which would result in beneficial owners of Voting Securities 
of the Company outstanding immediately prior thereto continuing to 
beneficially own securities representing (either by remaining outstanding or 
by being converted into voting securities of the surviving entity) more than 
twenty-five percent (25%) of the total Voting Securities of the Company, or 
of such surviving entity, outstanding immediately after such merger or 
consolidation, or (2) any person (as such term is used in Sections 13(d) or 
14(d) of the Exchange Act), other than (a) a trustee or other fiduciary 
holding securities under an employee benefit plan of the Company or (b) a 
corporation owned directly or indirectly by the shareholders of Company in 
substantially the same proportions as their ownership of stock in the 
Company, is or becomes the beneficial owner (within the meaning or Rule 13d-3 
under the Exchange Act), directly or indirectly, of the securities of the 
Company representing twenty-five percent (25%) or more of the Voting 
Securities of such corporation, and

              (B)  within twelve (12) months of the occurrence of such event, 
a change in the composition of the Company's Board occurs as a result of 
which sixty percent (60%) or fewer of the directors are Incumbent Directors.

    "Incumbent Directors" shall mean directors who either

              (A)  are directors of the Company as of the date hereof;

              (B)  are elected, or nominated for election, to the Board with 
the affirmative votes of at least a majority of the directors of the Company 
who are Incumbent Directors described in (A) above at the time of such 
election or nomination; or

              (C)  are elected, or nominated for election, to the Board with 
the affirmative votes of at least a majority of the directors of the Company 
who are Incumbent Directors described in (A) or (B) above at the time of such 
election or nomination.


                                     14


    Notwithstanding the foregoing, "Incumbent Directors" shall not include an 
individual whose election or nomination to the Board occurs in order to 
provide representation for a person or group of related persons who have 
initiated or encouraged an actual or threatened proxy contest relating to the 
election of directors of the Company.

14. AMENDMENT OF THE PLAN AND STOCK AWARDS.

    (a)  The Board at any time, and from time to time, may amend the Plan
and/or some or all outstanding Stock Awards granted under the Plan.  However,
except as provided in paragraph 13 relating to adjustments upon changes in
stock, no amendment shall be effective unless approved by the shareholders of
the Company to the extent shareholder approval is necessary for the Plan to
satisfy the requirements of Section 422 of the Code, Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

    (b)  The Board may in its sole discretion submit any other amendment to the
Plan for shareholder approval, including, but not limited to, amendments to the
Plan intended to satisfy the requirements of Section 162(m) of the Code and the
regulations promulgated thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to
certain executive officers.

    (c)  It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide eligible Employees
with the maximum benefits provided or to be provided under the provisions of the
Code and the regulations promulgated thereunder relating to Incentive Stock
Options and/or to bring the Plan and/or Incentive Stock Options granted under it
into compliance therewith.

    (d)  Rights and obligations under any Stock Award granted before amendment
of the Plan shall not be impaired by any amendment of the Plan unless (i) the
Company requests the consent of the person to whom the Stock Award was granted
and (ii) such person consents in writing.

    (e)  The Board at any time, and from time to time, may amend the terms of
any one or more Stock Award; provided, however, that the rights and obligations
under any Stock Award shall not be impaired by any such amendment unless (i) the
Company requests the consent of the person to whom the Stock Award was granted
and (ii) such person consents in writing.

15. TERMINATION OR SUSPENSION OF THE PLAN.

    (a)  The Board may suspend or terminate the Plan at any time.  Unless
sooner terminated, the Plan shall terminate on December 18, 2006 which shall be
within ten (10) years from the date the Plan is adopted by the Board or approved
by the shareholders of the Company, whichever is earlier.  No Stock Awards may
be granted under the Plan while the Plan is suspended or after it is terminated.


                                     15


    (b)  Rights and obligations under any Stock Award granted while the Plan 
is in effect shall not be impaired by suspension or termination of the Plan, 
except with the written consent of the person to whom the Stock Award was 
granted.

16. EFFECTIVE DATE OF PLAN.

    The Plan shall become effective as determined by the Board, but no Stock 
Awards granted under the Plan shall be exercised unless and until the Plan 
has been approved by the shareholders of the Company, which approval shall be 
within twelve (12) months before or after the date the Plan is adopted by the 
Board, and, if required, an appropriate permit has been issued by the 
Commissioner of Corporations of the State of California.
