                     1993 STOCK OPTION/STOCK ISSUANCE PLAN
                     -------------------------------------
                      (Amended through February 29, 1996)


                                  ARTICLE ONE
                                    GENERAL
                                    -------

      I.  PURPOSE OF THE PLAN


          A.  This 1993 Stock Option/Stock Issuance Plan (the "Plan") is
intended to promote the interests of Microelectronic Packaging, Inc., a
California corporation (the "Corporation"), by providing eligible individuals
with the opportunity to acquire a proprietary interest, or otherwise increase
their proprietary interest, in the Corporation as an incentive for them to
remain in the service of the Corporation (or its parent or subsidiary
corporations).

          B.  The Discretionary Option Grant and Stock Issuance Programs under
this Plan became effective on the date on which the shares of the Corporation's
Common Stock were first registered under Section 12(g) of the Securities
Exchange Act of 1934, as amended (the "1934 Act").  Such date is hereby
designated as the Plan Effective Date.  The Automatic Option Grant Program under
this Plan became effective immediately upon the execution and final pricing of
the Underwriting Agreement for the initial public offering of the Corporation's
Common Stock.  The execution date of such Underwriting Agreement is hereby
designated as the Automatic Grant Program Effective Date.

          C.  This Plan serves as the successor to the Corporation's 1988 Stock
Option Plan (the "Predecessor Plan"), and no further option grants or share
issuances shall be made under the Predecessor Plan from and after the Plan
Effective Date. All outstanding stock options and unvested share issuances under
the Predecessor Plan on such Plan Effective Date are hereby incorporated into
this Plan and shall accordingly be treated as outstanding stock options and
unvested share issuances under this Plan. However, each outstanding option grant
so incorporated shall continue to be governed solely by the express terms and
conditions of the instrument evidencing such grant, and no provision of this
Plan shall be deemed to affect or otherwise modify the rights or obligations of
the holders of such incorporated options with respect to their acquisition of
shares of the Corporation's Common Stock thereunder. All unvested shares of
Common Stock outstanding under the Predecessor Plan on the Plan Effective Date
shall continue to be governed solely by the express terms and conditions of the
instruments evidencing such issuances, and no provision of this Plan shall be
deemed to affect or modify the rights or obligations of the holders of such
unvested shares.

 
      II.  DEFINITIONS

           A.  For purposes of the Plan, the following definitions shall be in 
               effect:

           Change in Control: a change in ownership or control of the 
Corporation effected through either of the following transactions:

               (i)    the acquisition directly or indirectly by any person or
     related group of persons (other than the Corporation or a person that
     directly or indirectly controls, is controlled by, or is under common
     control with, the Corporation) of beneficial ownership (within the meaning
     of Rule 13d-3 of the 1934 Act) of securities possessing more than fifty
     percent (50%) of the total combined voting power of the Corporation's
     outstanding securities pursuant to a tender or exchange offer made directly
     to the Corporation's shareholders which the Board does not recommend such
     shareholders to accept; or

               (ii)   a change in the composition of the Board over a period of
     thirty-six (36) consecutive months or less such that a majority of the
     Board members ceases, by reason of one or more contested elections for
     Board membership, to be comprised of individuals who either (A) have been
     Board members continuously since the beginning of such period or (B) have
     been elected or nominated for election as Board members during such period
     by at least a majority of the Board members described in clause (A) who
     were still in office at the time such election or nomination was approved
     by the Board.

          Code:  the Internal Revenue Code of 1986, as amended.

          Committee:  the committee of two (2) or more non-employee Board
members appointed by the Board to administer the Plan.

          Common Stock:  shares of the Corporation's common stock.

          Corporate Transaction:  any of the following shareholder-approved
transactions to which the Corporation is a party:

     surviving entity, except for a transaction the principal purpose of which
     is to change the state in which the Corporation is incorporated,

                                       2.

 
               (ii) the sale, transfer or other disposition of all or
     substantially all of the assets of the Corporation in complete liquidation
     or dissolution of the Corporation, or

               (iii)  any reverse merger in which the Corporation is the
     surviving entity but in which securities possessing more than fifty percent
     (50%) of the total combined voting power of the Corporation's outstanding
     securities are transferred to a person or persons different from those who
     held such securities immediately prior to such merger.

          Employee:  an individual who performs services while in the employ of
the Corporation or one or more parent or subsidiary corporations, subject to the

          -    If the Common Stock is not at the time listed or admitted to
     trading on any national stock exchange but is traded on the Nasdaq National
     Market, the Fair Market Value shall be the closing selling price per share
     on the date in question, as such price is reported by the National
     Association of Securities Dealers through the Nasdaq National Market or any
     successor system.  If there is no reported closing selling price for the
     Common Stock on the date in question, then the closing selling price on the
     last preceding date for which such quotation exists shall be determinative
     of Fair Market Value.

          - If the Common Stock is at the time listed or admitted to trading on
     any national stock exchange, then the Fair Market Value shall be the
     closing selling price per share on the date in question on the exchange
     determined by the Plan Administrator to be the primary market for the
     Common Stock, as such price is officially quoted in the composite tape of
     transactions on such exchange. If there is no reported sale of Common Stock
     on such exchange on the date in question, then the Fair Market Value shall
     be the closing selling price on the exchange on the last preceding date for
     which such quotation exists.

          Optionee:  a person to whom an option is granted under the
Discretionary Option Grant or Automatic Option Grant Program.

          Participant:  a person who is issued Common Stock under the Stock

consultant or advisor, except to the extent otherwise specifically provided in
the applicable stock option or stock issuance agreement.

          B.   The following provisions shall be applicable in determining the
parent and subsidiary corporations of the Corporation:

               Any corporation (other than the Corporation) in an unbroken chain
     of corporations ending with the Corporation shall be considered to be a
     parent of the Corporation, provided each such corporation in the unbroken
     chain (other than the Corporation) owns, at the time of the determination,
     stock possessing fifty percent (50%) or more of the total combined voting
     power of all classes of stock in one of the other corporations in such
     chain.

               Each corporation (other than the Corporation) in an unbroken
     chain of corporations beginning with the Corporation shall be considered to
     be a subsidiary of the Corporation, provided each such corporation (other
     than the last corporation) in the unbroken chain owns, at the time of the
     determination, stock possessing fifty percent (50%) or more of the total
     combined voting power of all classes of stock in one of the other

     III. STRUCTURE OF THE PLAN

          A.   Stock Programs.  The Plan shall be divided into three separate
               --------------                                                
components: the Discretionary Option Grant Program specified in Article Two, the
Automatic Option Grant Program specified in Article Three and the Stock Issuance
Program specified in Article Four.  Under the Discretionary Option Grant
Program, eligible individuals may, at the discretion of the Plan Administrator,
be granted options to purchase shares of Common Stock in accordance with the
provisions of Article Two.  Under the Automatic Option Grant Program, each
individual serving as an eligible non-employee Board member on the Automatic
Grant Program Effective Date and each individual who first joins the Board as an
eligible non-employee director after the Automatic Grant Program Effective Date
will at periodic intervals receive option grants to purchase shares

                                       4.

 
of Common Stock in accordance with the provisions of Article Three, with the
first such grants to be made on the Automatic Grant Program Effective Date.
Under the Stock Issuance Program, eligible individuals may be issued shares of
Common Stock directly, either through the immediate purchase of such shares at a
price not less than eighty-five percent (85%) of the fair market value of the
shares at the time of issuance or as a bonus for past services rendered the
Corporation.

          B.   General Provisions.  Unless the context clearly indicates
               ------------------                                       
otherwise, the provisions of Articles One and Five shall apply to the
Discretionary Option Grant Program, the Automatic Option Grant Program and the
Stock Issuance Program and shall accordingly govern the interests of all
individuals under the Plan.

     IV.  ADMINISTRATION OF THE PLAN

          A.   Both the Discretionary Option Grant Program and the Stock
Issuance Program shall be administered by the Committee.  No non-employee Board
member shall be eligible to serve on the Committee if such individual has,
within the relevant period designated below, received an option grant or direct
stock issuance under this Plan or any other stock plan of the Corporation (or
any parent or subsidiary corporation), other than pursuant to the Automatic
Option Grant Program:

               (i) for each of the initial members of the Committee, the period
     commencing with the Plan Effective Date and ending with the date of his or
     her appointment to the Committee, or

               (ii) for any successor or substitute member, the twelve (12)-
     month period immediately preceding the date of his or her appointment to
     the Committee or (if shorter) the period commencing with the Plan Effective
     Date and ending with the date of his or her appointment to the Committee.

          Members of the Committee shall serve for such period of time as the
Board may determine and shall be subject to removal by the Board at any time.

          B.  The Committee as Plan Administrator shall have full power and
authority (subject to the express provisions of the Plan) to establish rules and
regulations for the proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of such programs and any outstanding option
grants or stock issuances thereunder as it may deem necessary or advisable.
Decisions of the Plan Administrator shall be final and binding on all parties
who have an interest in the Discretionary Option Grant or Stock Issuance Program
or any outstanding option or share issuance thereunder.

          C.  Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the express terms and conditions of Article
Three, and the 

                                       5.

 
Plan Administrator shall exercise no discretionary functions with respect to
option grants made pursuant to that program.

     V.  OPTION GRANTS AND STOCK ISSUANCES

          A.  The persons eligible to participate in the Discretionary Option
Grant Program under Article Two and the Stock Issuance Program under Article
Four shall be limited to the following:

               (i)  officers and other key employees of the Corporation (or its
     parent or subsidiary corporations) who render services which contribute to
     the management, growth and financial success of the Corporation (or its
     parent or subsidiary corporations); and

               (ii) those consultants or other independent contractors who
     provide valuable services to the Corporation (or its parent or subsidiary
     corporations).

          B.  The non-employee members of the Board shall not be eligible to
                                                          ---               
participate in the Discretionary Option Grant and Stock Issuance Programs or in
any other stock option, stock purchase, stock bonus or other stock plan of the
Corporation (or its parent or subsidiary corporations).  Non-employee members of
the Board shall, however, be eligible to receive automatic option grants
pursuant to the provisions of Article Three.

          C.  The Plan Administrator shall have full authority to determine, (i)
with respect to the option grants made under the Discretionary Option Grant
Program, which eligible individuals are to receive option grants, the number of
shares to be covered by each such grant, the status of the granted option as
either an incentive stock option ("Incentive Option") that satisfies the
requirements of Section 422 of the Code or a non-statutory option not intended
to meet such requirements, the time or times at which each granted option is to
become exercisable and the maximum term for which the option may remain
outstanding and (ii), with respect to stock issuances under the Stock Issuance
Program, the number of shares to be issued to each Participant, the vesting
schedule (if any) to be applicable to the issued shares, and the consideration
to be paid by the individual for such shares.

     VI.  STOCK SUBJECT TO THE PLAN

          A.  Shares of Common Stock shall be available for issuance under the
Plan and shall be drawn from either the Corporation's authorized but unissued
shares of Common Stock or from reacquired shares of Common Stock, including
shares repurchased by the Corporation on the open market.  The maximum number of
shares of Common Stock which may be issued over the term of the Plan shall not
exceed 690,632 shares, subject to adjustment from time to time in accordance
with the provisions of this Section VI.  Such authorized share reserve is
comprised of (i) the number of shares which remained for 

                                       6.

 
issuance, as of the Plan Effective Date, under the Predecessor Plan as last
approved by the Corporation's shareholders prior to such Plan Effective Date,
including the shares subject to the outstanding options incorporated into this
Plan and any other shares which would have been available for future option
grant under the Predecessor Plan as last approved by the shareholders, (ii) an
additional increase of 251,447 shares authorized by the Board under this Plan
and approved by the Corporation's shareholders prior to the Plan Effective Date
and (iii) additional increases of 110,000 shares and 190,000 shares authorized
by the Board on June 5, 1995 and February 29, 1996, respectively, subject to the
approval of the Corporation's shareholders at the 1996 Annual Meeting. To the
extent one or more outstanding options under the Predecessor Plan incorporated
into this Plan are subsequently exercised, the number of shares issued with
respect to each such option shall reduce, on a share-for-share basis, the number
of shares available for issuance under this Plan.

          B.  No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 500,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1996 calendar year.

          C.  Should one or more outstanding options under this Plan (including
outstanding options under the Predecessor Plan incorporated into this Plan)
expire or terminate for any reason prior to exercise in full (including any
option cancelled in accordance with the cancellation-regrant provisions of
Section IV of Article Two of the Plan), then the shares subject to the portion
of each option not so exercised shall be available for subsequent option grants
under the Plan.  All share issuances under the Plan (including unvested share
issuances under the Predecessor Plan which have been incorporated into this
Plan), whether or not the shares are subsequently repurchased by the Corporation
pursuant to its repurchase rights under the Plan, shall reduce on a share-for-
share basis the number of shares of Common Stock available for subsequent option
grants under the Plan.  In addition, should the exercise price of an outstanding
option under the Plan (including any option incorporated from the Predecessor
Plan) be paid with shares of Common Stock or should shares of Common Stock
otherwise issuable under the Plan be withheld by the Corporation in satisfaction
of the withholding taxes incurred in connection with the exercise of an
outstanding option under the Plan or the vesting of a direct share issuance made
under the Plan, then the number of shares of Common Stock available for issuance
under the Plan shall be reduced by the gross number of shares for which the
option is exercised or which vest under the share issuance, and not by the net
number of shares of Common Stock actually issued to the holder of such option or
share issuance.

          D.  Should any change be made to the Common Stock issuable under the
Plan by reason of any stock split, stock dividend, recapitalization, combination
of shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration, then
appropriate adjustments shall be made to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the number and/or class of securities
for which any one person may be granted options, separately exercisable stock
appreciation rights and direct stock issuances per calendar year, 

                                       7.

 
(iii) the number and/or class of securities for which automatic option grants
are to be subsequently made per eligible non-employee Board member under the
Automatic Option Grant Program, (iv) the number and/or class of securities and
price per share in effect under each option outstanding under either the
Discretionary Option Grant or Automatic Option Grant Program and (v) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from the Predecessor Plan. Such adjustments
to the outstanding options are to be effected in a manner which shall preclude
the enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

                                       8.

 
                                  ARTICLE TWO

                      DISCRETIONARY OPTION GRANT PROGRAM
                      ----------------------------------


        I.      TERMS AND CONDITIONS OF OPTIONS


                Options granted pursuant to the Discretionary Option Grant
Program shall be authorized by action of the Plan Administrator and may, at the
Plan Administrator's discretion, be either Incentive Options or non-statutory
options. Individuals who are not Employees of the Corporation or its parent or
subsidiary corporations may only be granted non-statutory options. Each granted
option shall be evidenced by one or more instruments in the form approved by the
Plan Administrator; provided, however, that each such instrument shall comply
                    --------                                                 
with the terms and conditions specified below.  Each instrument evidencing an
Incentive Option shall, in addition, be subject to the applicable provisions of
Section II of this Article Two.

                A.      Option Price.
                        ------------ 

                        1.      The option price per share shall be fixed by the
Plan Administrator in accordance with the following provisions:

                                (i)     The option price per share of Common
     Stock subject to an Incentive Option shall in no event be less than one
     hundred percent (100%) of the Fair Market Value of such Common Stock on the
     grant date.

                                (ii)    The option price per share of Common
     Stock subject to a non-statutory stock option shall in no event be less
     than eighty-five percent (85%) of the Fair Market Value of such Common
     Stock on the grant date.

                        2.      The option price shall become immediately due
upon exercise of the option and, subject to the provisions of Section I of
Article Five and the instrument evidencing the grant, shall be payable in one of
the following alternative forms specified below:

                                 (i)    full payment in cash or check drawn to
     the Corporation's order;

                                (ii)    full payment in shares of Common Stock
     held for the requisite period necessary to avoid a charge to the
     Corporation's earnings for financial reporting purposes and valued at Fair
     Market Value on the Exercise Date (as such term is defined below);

                                       9.

 
                                (iii)   full payment in a combination of shares
     of Common Stock held for the requisite period necessary to avoid a charge
     to the Corporation's earnings for financial reporting purposes and valued
     at Fair Market Value on the Exercise Date and cash or check drawn to the
     Corporation's order; or

                                (iv)    full payment through a broker-dealer
     sale and remittance procedure pursuant to which the Optionee shall provide
     irrevocable written instructions to (I) a Corporation-designated brokerage
     firm to effect the immediate sale of the purchased shares and remit to the
     Corporation, out of the sale proceeds available on the settlement date,
     sufficient funds to cover the aggregate option price payable for the
     purchased shares plus all applicable Federal and state income and
     employment taxes required to be withheld by the Corporation in connection
     with such purchase and (II) the Corporation to deliver the certificates for
     the purchased shares directly to such brokerage firm in order to complete
     the sale transaction.

          For purposes of this subparagraph 2, the Exercise Date shall be the
date on which written notice of the option exercise is delivered to the
Corporation.  Except to the extent the sale and remittance procedure is used in
connection with the exercise of the option, payment of the option price for the
purchased shares must accompany such notice.

          B.  Term and Exercise of Options.  Each option granted under this
              ----------------------------                                 
Discretionary Option Grant Program shall be exercisable at such time or times
and during such period as is determined by the Plan Administrator and set forth
in the instrument evidencing the grant.  No such option, however, shall have a
maximum term in excess of ten (10) years from the grant date.  During the
lifetime of the Optionee, the option shall be exercisable only by the Optionee
and shall not be assignable or transferable by the Optionee other than by will
or by the laws of descent and distribution following the Optionee's death.

          C.  Termination of Service.
              ---------------------- 

              1.  The following provisions shall govern the exercise period
applicable to any outstanding options held by the Optionee at the time of
cessation of Service or death.

               (i) Should an Optionee cease Service for any reason (other than
     death) while holding one or more outstanding options under this Article
     Two, then none of those options shall remain exercisable for more than a
     ninety (90)-day period (or such shorter period determined by the Plan
     Administrator and set forth in the instrument evidencing the grant)
     measured from the date of such cessation of Service.

                                      10.

 
               (ii)     Any option held by the Optionee under this Article Two
     and exercisable in whole or in part on the date of his or her death may be
     subsequently exercised by the personal representative of the Optionee's
     estate or by the person or persons to whom the option is transferred
     pursuant to the Optionee's will or in accordance with the laws of descent
     and distribution. Such exercise, however, must occur prior to the earlier
                                                                       -------
     of (A) six (6) months measured from the date of the Optionee's death or (B)
     the specified expiration date of the option term.  Upon the occurrence of
     the earlier event, the option shall terminate.

               (iii)    Under no circumstances shall any such option be
     exercisable after the specified expiration date of the option term.

               (iv)     During the applicable post-Service exercise period, the
     option may not be exercised in the aggregate for more than the number of
     shares (if any) in which the Optionee is vested at the time of his or her
     cessation of Service.  Upon the expiration of the limited post-Service
     exercise period or (if earlier) upon the specified expiration date of the
     option term, each such option shall terminate and cease to be outstanding
     with respect to any vested shares for which the option has not otherwise
     been exercised.  However, each outstanding option shall immediately
     terminate and cease to be outstanding, at the time of the Optionee's
     cessation of Service, with respect to any shares for which the option is
     not otherwise at that time exercisable or in which the Optionee is not
     otherwise vested.

               (v)      Should (A) the Optionee's Service be terminated for
     misconduct (including, but not limited to, any act of dishonesty, willful
     misconduct, fraud or embezzlement) or (B) the Optionee make any
     unauthorized use or disclosure of confidential information or trade secrets
     of the Corporation or its parent or subsidiary corporations, then in any
     such event all outstanding options held by the Optionee under this Article
     Two shall terminate immediately and cease to be outstanding.

          2.  The Plan Administrator shall have complete discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to permit one or more options held by the Optionee under this
Article Two to be exercised, during the limited post-Service exercise period
applicable under subparagraph 1 above, not only with respect to the number of
vested shares of Common Stock for which each such option is exercisable at the
time of the Optionee's cessation of Service but also with respect to one or more
subsequent installments in which Optionee would have otherwise vested had such
cessation of Service not occurred.

                                      11.

 
          D.  Shareholder Rights.
              ------------------ 

              An Optionee shall have no shareholder rights with respect to any
shares covered by the option until such individual shall have exercised the
option and paid the option price for the purchased shares.

          E.  Repurchase Rights.
              ----------------- 

              The shares of Common Stock acquired upon the exercise of any
Article Two option grant may be subject to repurchase by the Corporation in
accordance with the following provisions:

               (i) The Plan Administrator shall have the discretion to authorize
     the issuance of unvested shares of Common Stock under this Article Two.
     Should the Optionee cease Service while holding such unvested shares, the
     Corporation shall have the right to repurchase any or all of those unvested
     shares at the option price paid per share.  The terms and conditions upon
     which such repurchase right shall be exercisable (including the period and
     procedure for exercise and the appropriate vesting schedule for the
     purchased shares) shall be established by the Plan Administrator and set
     forth in the instrument evidencing such repurchase right.

               (ii) All of the Corporation's outstanding repurchase rights under
     this Article Two shall automatically terminate, and all shares subject to
     such terminated rights shall immediately vest in full, upon the occurrence
     of a Corporate Transaction, except to the extent:  (A) any such repurchase
     right is expressly assigned to the successor corporation (or parent
     thereof) in connection with the Corporate Transaction or (B) such
     termination is precluded by other limitations imposed by the Plan
     Administrator at the time the repurchase right is issued.

               (iii)     The Plan Administrator shall have the discretionary
     authority, exercisable either before or after the Optionee's cessation of
     Service, to cancel the Corporation's outstanding repurchase rights with
     respect to one or more shares purchased or purchasable by the Optionee
     under this Article Two and thereby accelerate the vesting of such shares in
     whole or in part at any time.

     II.  INCENTIVE OPTIONS

          The terms and conditions specified below shall be applicable to all
Incentive Options granted under this Article Two.  Incentive Options may only be
granted to individuals who are Employees.  Options which are specifically
designated as "non-statutory" options when issued under the Plan shall not be
                                                                       ---   
subject to such terms and conditions.

                                      12.

 
          A.  Dollar Limitation.  The aggregate Fair Market Value (determined as
              -----------------                                                 
of the respective date or dates of grant) of the Common Stock for which one or
more options granted to any Employee after December 31, 1986 under this Plan (or
any other option plan of the Corporation or its parent or subsidiary
corporations) may for the first time become exercisable as incentive stock
options under the Federal tax laws during any one calendar year shall not exceed
the sum of One Hundred Thousand Dollars ($100,000).  To the extent the Employee
holds two (2) or more such options which become exercisable for the first time
in the same calendar year, the foregoing limitation on the exercisability of
such options as incentive stock options under the Federal tax laws shall be
applied on the basis of the order in which such options are granted.  Should the
number of shares of Common Stock for which any Incentive Option first becomes
exercisable in any calendar year exceed the applicable One Hundred Thousand
Dollar ($100,000) limitation, then that option may nevertheless be exercised in
that calendar year for the excess number of shares as a non-statutory option
under the Federal tax laws.

          B.  10% Shareholder.  If any individual to whom an Incentive Option is
              ---------------                                                   
granted is the owner of stock (as determined under Section 424(d) of the Code)
possessing ten percent (10%) or more of the total combined voting power of all
classes of stock of the Corporation or any one of its parent or subsidiary
corporations, then the option price per share shall not be less than one hundred
ten percent (110%) of the Fair Market Value per share of Common Stock on the
grant date, and the option term shall not exceed five (5) years, measured from
the grant date.

          Except as modified by the preceding provisions of this Section II, the
provisions of Articles One, Two and Five of the Plan shall apply to all
Incentive Options granted hereunder.

     III. CORPORATE TRANSACTIONS/CHANGES IN CONTROL

          A.  In the event of any Corporate Transaction, each option which is at
the time outstanding under this Article Two shall automatically accelerate so
that each such option shall, immediately prior to the specified effective date
for the Corporate Transaction, become fully exercisable with respect to the
total number of shares of Common Stock at the time subject to such option and
may be exercised for all or any portion of such shares.  However, an outstanding
option under this Article Two shall not so accelerate if and to the extent:  (i)
such option is, in connection with the Corporate Transaction, either to be
assumed by the successor corporation or parent thereof or to be replaced with a
comparable option to purchase shares of the capital stock of the successor
corporation or parent thereof, (ii) such option is to be replaced with a cash
incentive program of the successor corporation which preserves the option spread
existing at the time of the Corporate Transaction and provides for subsequent
payout in accordance with the same vesting schedule applicable to such option,
or (iii) the acceleration of such option is subject to other limitations imposed
by the Plan Administrator at the time of the option grant.  The determination of
option 

                                      13.

 
comparability under clause (i) above shall be made by the Plan Administrator,
and its determination shall be final, binding and conclusive.

          B.  Immediately following the consummation of the Corporate
Transaction, all outstanding options under this Article Two shall terminate and
cease to be outstanding, except to the extent assumed by the successor
corporation or its parent company.

          C.  Each outstanding option under this Article Two which is assumed in
connection with the Corporate Transaction or is otherwise to continue in effect
shall be appropriately adjusted, immediately after such Corporate Transaction,
to apply and pertain to the number and class of securities which would have been
issued to the option holder, in consummation of such Corporate Transaction, had
such person exercised the option immediately prior to such Corporate
Transaction.  Appropriate adjustments shall also be made to the option price
payable per share, provided the aggregate option price payable for such
                   --------                                            
securities shall remain the same.  In addition, the class and number of
securities available for issuance under the Plan following the consummation of
the Corporate Transaction shall be appropriately adjusted.

          D.  The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide (upon such terms as it may deem appropriate) for the
automatic acceleration of one or more outstanding options granted under the Plan
that are assumed or replaced in a Corporate Transaction and do not otherwise
accelerate at that time, in the event the Optionee's Service should subsequently
terminate within a designated period following the effective date of such
Corporate Transaction.

          E.  The grant of options under this Article Two shall in no way affect
the right of the Corporation to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

          F.  The Plan Administrator shall have the discretionary authority,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to provide for the automatic acceleration of one or
more outstanding options under this Article Two (and the termination of one or
more of the Corporation's outstanding repurchase rights under this Article Two)
upon the occurrence of a Change in Control.  The Plan Administrator shall also
have full power and authority to condition any such option acceleration (and the
termination of any outstanding repurchase rights) upon the subsequent
termination of the Optionee's Service within a specified period following the
Change in Control.

          G.  Any options accelerated in connection with the Change in Control
shall remain fully exercisable until the expiration or sooner termination of the
option term.

                                      14.

 
          H.  The exercisability as incentive stock options under the Federal
tax laws of any options accelerated under this Section III in connection with a
Corporate Transaction or Change in Control shall remain subject to the dollar
limitation of Section II of this Article Two.  To the extent such dollar
limitation is exceeded, the accelerated option shall be exercisable as a non-
statutory option under the Federal tax laws.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected optionees, the
cancellation of any or all outstanding options under this Article Two (including
outstanding options under the Predecessor Plan incorporated into this Plan) and
to grant in substitution new options under the Plan covering the same or
different numbers of shares of Common Stock but with an option price per share
not less than (i) one hundred percent (100%) of the Fair Market Value on the new
grant date in the case of a grant of an Incentive Option, (ii) one hundred ten
percent (110%) of such Fair Market Value in the case of a grant of an Incentive
Option to a 10% Shareholder or (iii) eighty-five percent (85%) of such Fair
Market Value in the case of all other grants.

     V.   INITIAL GRANTS

          For purposes of option grants made at the time of the Common Stock is
first registered under Section 12(g) of the 1934 Act or at any time thereafter
prior to the time the Common Stock is first traded on a national securities
exchange or the Nasdaq National Market, the Fair Market Value of the Common
Stock at such time shall be deemed to be equal to the price per share at which
the Common Stock is sold in the initial public offering pursuant to the
Underwriting Agreement.

                                      15.

the provisions of this Automatic Option Grant Program, Eligible Directors shall
                                                                               
not be eligible to receive any additional option grants or stock issuances under

subsidiaries).

     II.  TERMS AND CONDITIONS OF AUTOMATIC OPTION GRANTS
         
          A.      Grant Dates.  Option grants shall be made under this Article
                  -----------                         
Three on the dates specified below:

such individual is standing for re-election as a Board member at that Annual
Meeting, a Non-Statutory Option to purchase an additional 900 shares of Common
Stock upon the terms and conditions of this Article Three, provided he or she
has served as a non-employee Board 

                                      16.

 
member for at least six (6) months prior to the date of such Annual Meeting.
There shall be no limit on the number of such 900-share option grants any one
Eligible Director may receive over his or her period of Board service.

          B.  Exercise Price. The exercise price per share of Common Stock
              --------------                                              
subject to each automatic option grant made under this Article Three shall be
determined in accordance with the following provisions:

          -    For the automatic option grants made on the Automatic Grant
     Program Effective Date, the exercise price per share of Common Stock shall
     be equal to the price per share at which the Common Stock is sold in the
     initial public offering of the Common Stock pursuant to the Underwriting

          C.   Payment.

               The exercise price shall be payable in one of the alternative
forms specified below:
 
               (i) full payment in cash or check drawn to the Corporation's

     requisite period necessary to avoid a charge to the Corporation's earnings
     for financial reporting purposes and valued at Fair Market Value on the
     Exercise Date (as such term is defined below);

               (iii)     full payment in a combination of shares of Common Stock
     held for the requisite period necessary to avoid a charge to the
     Corporation's earnings for financial reporting purposes and valued at Fair
     Market Value on the Exercise Date and cash or check drawn to the
     Corporation's order; or

               (iv) full payment through a sale and remittance procedure
     pursuant to which the Optionee shall provide irrevocable written
     instructions to (I) a Corporation-designated brokerage firm to effect the
     immediate sale of the purchased shares and remit to the Corporation, out of
     the sale proceeds available on the settlement date, sufficient funds to
     cover the aggregate exercise price payable for the purchased shares and
     (II) the 

                                      17.

 
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale transaction.

          For purposes of this subparagraph C, the Exercise Date shall be the
date on which written notice of the option exercise is delivered to the
Corporation.  Except to the extent the sale and remittance procedure specified
above is used for the exercise of the option for vested shares, payment of the
exercise price for the purchased shares must accompany the exercise notice.

          D.  Option Term.  Each automatic grant under this Article Three shall
              -----------                                                      
have a maximum term of ten (10) years measured from the automatic grant date.

          E.  Exercisability.  Each automatic grant shall become exercisable in
              --------------                                                   
a series of four (4) equal and successive annual installments over the
Optionee's period of continued service as a Board member, with the first such
installment to become exercisable one (1) year after the automatic grant date.
The exercisability of each automatic grant outstanding under this Article Three
shall be accelerated as provided in Section II.G and Section III of this Article
Three.

          F.  Non-Transferability.  During the lifetime of the Optionee, each
              -------------------                                            
automatic option grant shall be exercisable only by the Optionee and shall not
be assignable or transferable by the Optionee other than by will or by the laws
of descent and distribution following Optionee's death.

          G.  Effect of Termination of Board Membership.
              ----------------------------------------- 

              1.  Should the Optionee cease to serve as a Board member for any
reason (other than death or Permanent Disability) while holding one or more
automatic option grants under this Article Three, then such individual shall
have a ninety (90)-day period following the date of such cessation of Board
membership in which to exercise each such option for any or all of the shares of
Common Stock for which that option is exercisable at the time of such cessation
of Board service.  Each such option shall immediately terminate and cease to be
outstanding, at the time of such cessation of Board service, with respect to any
shares for which the option is not otherwise at that time exercisable.

              2.  Should the Optionee die within ninety (90) days after
cessation of Board service, then any automatic option grant held by the Optionee
at the time of death may subsequently be exercised, for any or all of the shares
of Common Stock for which such option is exercisable at the time of the
Optionee's cessation of Board membership (less any option shares subsequently
purchased by the Optionee prior to death), by the personal representative of the
Optionee's estate or by the person or persons to whom the option is transferred
pursuant to the Optionee's will or in accordance with the laws of descent and

                                      18.

 
distribution. Any such exercise must occur within six (6) months after the date
of the Optionee's death.

              3.  Should the Optionee die or become Permanently Disabled while
serving as a Board member, then any automatic option grant held by such Optionee
under this Article Three shall accelerate in full, and the Optionee (or the
representative of the Optionee's estate or the person or persons to whom the
option is transferred upon the Optionee's death) shall have a six (6)-month
period following the date of the Optionee's cessation of Board membership in
which to exercise such option for any or all of the shares of Common Stock
subject to the option at the time of such cessation of Board membership.

              4.  In no event shall any automatic grant under this Article Three
remain exercisable after the expiration date of the ten (10)-year option term.
Upon the expiration of the applicable post-service exercise period under
subparagraph 1, 2 or 3 above or (if earlier) upon the expiration of the ten
(10)-year option term, the automatic grant shall terminate and cease to be
outstanding for any unexercised shares for which the option was otherwise
exercisable at the time of the Optionee's cessation of Board membership.

          H.  Shareholder Rights.  The holder of an automatic option grant under
              ------------------                                                
this Article Three shall have none of the rights of a shareholder with respect
to any RESTRICTIONS shares subject to such option until such individual shall
have exercised the option and paid the exercise price for the purchased shares.

          I.  Remaining Terms.  The remaining terms and conditions of each
              ---------------                                             
automatic option grant shall be as set forth in the form Director Automatic
Grant Agreement attached as Exhibit A.

     III.  CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.  In the event of any Corporate Transaction, each automatic option
grant at the time outstanding under this Article Three shall automatically
accelerate so that each such option shall, immediately prior to the specified
effective date for the Corporate Transaction, become fully exercisable with
respect to the total number of shares of Common Stock at the time subject to
such option and may be exercised for all or any portion of those shares as
fully-vested shares.  Immediately after the consummation of the Corporate
Transaction, all automatic option grants under this Article Three shall
terminate and cease to be outstanding.

          B.  In connection with any Change in Control, each automatic option
grant at the time outstanding under this Article Three shall automatically
accelerate so that each such option shall, immediately prior to the specified
effective date for the Change in Control, become fully exercisable with respect
to the total number of shares of Common Stock at the time subject to such option
and may be exercised for all or any portion of those shares as fully-vested
shares.  Any option accelerated in connection with the Change in 

                                      19.

 
Control shall remain fully exercisable until the expiration or sooner
termination of the option term.

          C.  The automatic option grants outstanding under this Article Three
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     IV.  AMENDMENT OF THE AUTOMATIC GRANT PROVISIONS

          The provisions of this Automatic Option Grant Program, together with
the automatic option grants outstanding under this Article Three, may not be
amended at intervals more frequently than once every six (6) months, other than
to the extent necessary to comply with applicable Federal income tax laws and
regulations.

Issuance Program, namely:

                                      21.

 
               (i)      the Service period to be completed by the Participant or
     the performance objectives to be achieved by the Corporation,

               (ii)     the number of installments in which the shares are to
     vest,

               (iii)    the interval or intervals (if any) which are to lapse
     between installments, and

               (iv)     the effect which death, Permanent Disability or other
     event designated by the Plan Administrator is to have upon the vesting
     schedule,

shall be determined by the Plan Administrator and incorporated into the Issuance
Agreement executed by the Corporation and the Participant at the time such
unvested shares are issued.

          2.  The Participant shall have full shareholder rights with respect to
any shares of Common Stock issued to him or her under the Plan, whether or not
his or her interest in those shares is vested.  Accordingly, the Participant
shall have the right to vote such shares and to receive any regular cash
dividends paid on such shares.  Any new, additional or different shares of stock
or other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to his or her
unvested shares by reason of any stock dividend, stock split, reclassification
of Common Stock or other similar change in the Corporation's capital structure
or by reason of any Corporate Transaction shall be issued, subject to (i) the
same vesting requirements applicable to his or her unvested shares and (ii) such
escrow arrangements as the Plan Administrator shall deem appropriate.

          3.  Should the Participant cease to remain in Service while holding
one or more unvested shares of Common Stock under the Plan, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further shareholder rights with respect to those
shares.  To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money promissory note), the Corporation shall repay to
the Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to such surrendered shares.

          4.  The Plan Administrator may in its discretion elect to waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the non-
completion of the vesting schedule applicable to such shares.  Such waiver shall
result in the immediate vesting of the Participant's interest in the shares of
Common Stock as to which the waiver applies.  

                                      22.

 
Such waiver may be effected at any time, whether before or after the
Participant's cessation of Service.

     II.  CORPORATE TRANSACTIONS/CHANGE IN CONTROL

          A.  Upon the occurrence of any Corporate Transaction, all unvested
shares of Common Stock at the time outstanding under the Stock Issuance Program
shall immediately vest in full, except to the extent the Plan Administrator
imposes limitations in the Issuance Agreement which preclude such accelerated
vesting in whole or in part.

          B.  The Plan Administrator shall have the discretionary authority,
exercisable either at the time the shares are issued under the Stock Issuance
Program or at any time while the issued shares remain unvested, to provide for
the immediate and automatic vesting of one or more of those shares at the time
of a Change in Control.  The Plan Administrator shall also have full power and
authority to condition any such accelerated vesting upon the subsequent
termination of the Participant's Service within a specified period following the
Change in Control.

     III.  TRANSFER RESTRICTIONS/SHARE ESCROW

          A.  Unvested shares may, in the Plan Administrator's discretion, be
held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing such unvested shares.  To the extent an
escrow arrangement is utilized, the unvested shares and any securities or other
assets issued with respect to such shares (other than regular cash dividends)
shall be delivered in escrow to the Corporation to be held until the
Participant's interest in such shares (or other securities or assets) vests.
Alternatively, if the unvested shares are issued directly to the Participant,
the restrictive legend on the certificates for such shares shall read
substantially as follows:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE UNVESTED AND ARE
     ACCORDINGLY SUBJECT TO (I) CERTAIN TRANSFER AND (II) CANCELLATION OR
     REPURCHASE IN THE EVENT THE REGISTERED HOLDER (OR HIS/HER PREDECESSOR IN
     INTEREST) CEASES TO REMAIN IN THE CORPORATION'S SERVICE.  SUCH TRANSFER
     RESTRICTIONS AND THE TERMS AND CONDITIONS OF SUCH CANCELLATION OR
     REPURCHASE ARE SET FORTH IN A STOCK ISSUANCE AGREEMENT BETWEEN THE
     CORPORATION AND THE REGISTERED HOLDER (OR HIS/HER PREDECESSOR IN INTEREST)
     DATED ________________, 199__, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
     OFFICE OF THE CORPORATION."

                                      23.

 
          B.   The Participant shall have no right to transfer any unvested
shares of Common Stock issued to him or her under the Stock Issuance Program.
For purposes of this restriction, the term "transfer" shall include (without
limitation) any sale, pledge, assignment, encumbrance, gift, or other
disposition of such shares, whether voluntary or involuntary.  Upon any such
attempted transfer, the unvested shares shall immediately be cancelled, and
neither the Participant nor the proposed transferee shall have any rights with
respect to those shares.  However, the Participant shall have the right to make
a gift of unvested shares acquired under the Stock Issuance Program to his or
her spouse or issue, including adopted children, or to a trust established for
such spouse or issue, provided the donee of such shares delivers to the
Corporation a written agreement to be bound by all the provisions of the Stock
Issuance Program and the Issuance Agreement applicable to the gifted shares.

                                      24.

 
                                 ARTICLE FIVE

                                 MISCELLANEOUS
                                 -------------


     I.   LOANS OR INSTALLMENT PAYMENTS

          A.  The Plan Administrator may, in its discretion, assist any Optionee
or Participant (including an Optionee or Participant who is an officer of the
Corporation) in the exercise of one or more options granted to such Optionee
under the Discretionary Option Grant Program or the purchase of one or more
shares issued to such Participant under the Stock Issuance Program, including
the satisfaction of any Federal and state income and employment tax obligations
arising therefrom, by (i) authorizing the extension of a loan from the
Corporation to such Optionee or Participant or (ii) permitting the Optionee or
Participant to pay the option price or purchase price for the purchased Common
Stock in installments over a period of years.  The terms of any loan or
installment method of payment (including the interest rate and terms of
repayment) shall be upon such terms as the Plan Administrator specifies in the
applicable option or issuance agreement or otherwise deems appropriate under the
circumstances.  Loans or installment payments may be authorized with or without
security or collateral.  However, any loan made to a consultant or other non-
employee advisor must be secured by property other than the purchased shares of
Common Stock.  In all events, the maximum credit available to the Optionee or
Participant may not exceed the option or purchase price of the acquired shares
plus any Federal and state income and employment tax liability incurred by the
Optionee or Participant in connection with the acquisition of such shares.

          B.  The Plan Administrator may, in its absolute discretion, determine
that one or more loans extended under this financial assistance program shall be
subject to forgiveness by the Corporation in whole or in part upon such terms
and conditions as the Plan Administrator may deem appropriate.

     II.  AMENDMENT OF THE PLAN AND AWARDS

          A.  The Board has complete and exclusive power and authority to amend
or modify the Plan (or any component thereof) in any or all respects whatsoever.
However, (i) no such amendment or modification shall adversely affect rights and
obligations with respect to options at the time outstanding under the Plan, nor
adversely affect the rights of any Participant with respect to Common Stock
issued under the Stock Issuance Program prior to such action, unless the
Optionee or Participant consents to such amendment, and (ii) any amendment made
to the Automatic Option Grant Program (or any options outstanding thereunder)
shall be in compliance with the limitation of Section IV of Article Three.  In
addition, the Board may not, without the approval of the Corporation's
shareholders, amend the Plan to (i) materially increase the maximum number of
shares 

                                      25.

 
issuable under the Plan, the number of shares for which options may be granted
under the Automatic Option Grant Program, or the maximum number of shares for
which any one person may be granted options, separately exercisable stock
appreciation rights and direct stock issuances per calendar year, except for
permissible adjustments under Section VI.C. of Article One, (ii) materially
modify the eligibility requirements for Plan participation or (iii) materially
increase the benefits accruing to Plan participants.

          B.  (i)  Options to purchase shares of Common Stock may be granted
under the Discretionary Option Grant Program and (ii) shares of Common Stock may
be issued under the Stock Issuance Program, which are in both instances in
excess of the number of shares then available for issuance under the Plan,
provided any excess shares actually issued under the Discretionary Option Grant
Program or the Stock Issuance Program are held in escrow until shareholder
approval is obtained for a sufficient increase in the number of shares available
for issuance under the Plan.  If such shareholder approval is not obtained
within twelve (12) months after the date the first such excess option grants or
excess share issuances are made, then (I) any unexercised excess options shall
terminate and cease to be exercisable and (II) the Corporation shall promptly
refund the purchase price paid for any excess shares actually issued under the
Plan and held in escrow, together with interest (at the applicable Short Term
Federal Rate) for the period the shares were held in escrow.

     III. TAX WITHHOLDING

          The Corporation's obligation to deliver shares of Common Stock upon
the exercise of stock options for such shares or the vesting of such shares
under the Plan shall be subject to the satisfaction of all applicable Federal,
state and local income tax and employment tax withholding requirements.

          The Plan Administrator may, in its discretion and in accordance with
the provisions of this Section III of Article Five and such supplemental rules
as the Plan Administrator may from time to time adopt (including the applicable
safe-harbor provisions of Rule 16b-3 of the Securities and Exchange Commission),
provide any or all holders of non-statutory options (other than the automatic
grants made pursuant to Article Three of the Plan) or unvested shares under the
Plan with the right to use shares of Common Stock in satisfaction of all or part
of the Federal, state and local income and employment tax liabilities incurred
by such holders in connection with the exercise of their options or the vesting
of their shares (the "Taxes").  Such right may be provided to any such holder in
either or both of the following formats:

                (i)     Stock Withholding: The holder of the non-statutory
                        -----------------
     option or unvested shares may be provided with the election to have the
     Corporation withhold, from the shares of Common Stock otherwise issuable
     upon the exercise of such non-statutory option or the vesting of such
     shares, a portion of those shares with an aggregate Fair Market Value 
     equal  

                                      26.

 
     to the percentage of the applicable Taxes (not to exceed one hundred
     percent (100%)) designated by the holder.

               (ii)     Stock Delivery:  The Plan Administrator may, in its
                        --------------                                     
     discretion, provide the holder of the non-statutory option or the unvested
     shares with the election to deliver to the Corporation, at the time the
     non-statutory option is exercised or the shares vest, one or more shares of
     Common Stock previously acquired by such individual (other than in
     connection with the option exercise or share vesting triggering the Taxes)
     with an aggregate Fair Market Value equal to the percentage of the Taxes
     incurred in connection with such option exercise or share vesting (not to
     exceed one hundred percent (100%)) designated by the holder.

     IV.  EFFECTIVE DATE AND TERM OF PLAN

          A.  Provided this Plan is approved by the Corporation's shareholders
on or before the Plan Effective Date, this Plan shall, as successor to the
Predecessor Plan, become effective as of such Effective Date, and no further
option grants or stock issuances shall be made under the Predecessor Plan from
and after the Plan Effective Date.

          B.  Each stock option grant outstanding under the Predecessor Plan
immediately prior to the Plan Effective Date shall be incorporated into this
Plan and treated as an outstanding option under this Plan, but each such option
shall continue to be governed solely by the terms and conditions of the
instrument evidencing such grant, and nothing in this Plan shall be deemed to
affect or otherwise modify the rights or obligations of the holders of such
options with respect to their acquisition of shares of Common Stock thereunder.
Each unvested share of Common Stock outstanding under the Predecessor Plan on
the Plan Effective Date shall continue to be governed solely by the terms and
conditions of the instrument evidencing such share issuance, and nothing in this
Plan shall be deemed to affect or otherwise modify the rights or obligations of
the holder of such unvested shares.

          C.  The option/vesting acceleration provisions of Section III of
Article Two and Section II of Article Four relating to Corporate Transactions
and Changes in Control may, in the Plan Administrator's discretion, be extended
to one or more stock options or unvested share issuances which are outstanding
under the Predecessor Plan on the Plan Effective Date but which do not otherwise
provide for such acceleration.

          D.  The Plan was amended by the Board on June 5, 1995 to increase the
number of shares of Common Stock authorized for issuance under the Plan by an
additional 110,000 shares, and the Plan was further amended by the Board on
February 29, 1996 to (i) increase the number of shares of Common Stock
authorized for issuance under the Plan by an additional 190,000 shares and (ii)
establish a 500,000-share limit on the aggregate number of shares of Common
Stock for which any one participant may be issued stock options and direct stock
issuances over the remaining term of the Plan.   Each of the amendments is

                                      27.

 
subject to shareholder approval at the 1996 Annual Shareholders Meeting, and no
option granted on the basis of the share increases authorized by those
amendments shall become exercisable in whole or in part unless and until such
shareholder approval is obtained.  If such shareholder approval is not obtained
at the 1996 Annual Meeting, then all options granted on the basis of those share
increases shall immediately terminate without ever becoming exercisable for the
non-approved shares, and no further option grants shall be made on the basis of
those increases.  However, the Plan shall continue in effect until the reserve
of Common Stock under the Plan as last approved by the Corporation's
shareholders shall have been issued.

          E.  The Plan shall terminate upon the earlier of (i) December 8, 2003
                                                -------                        
or (ii) the date on which all shares available for issuance under the Plan shall
have been issued pursuant to the exercise of the options granted under the Plan
or the issuance of shares (whether vested or unvested) under the Stock Issuance
Program.  If the date of termination is determined under clause (i) above, then
all option grants and unvested share issuances outstanding on such date shall
thereafter continue to have force and effect in accordance with the provisions
of the instruments evidencing such grants or issuances.


     V.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
pursuant to option grants or share issuances under the Plan shall be used for
general corporate purposes

     VI.  REGULATORY APPROVALS

          A.  The implementation of the Plan, the granting of any option under
the Plan, the issuance of any shares under the Stock Issuance Program, and the
issuance of Common Stock upon the exercise or surrender of the option grants
made hereunder shall be subject to the Corporation's procurement of all
approvals and permits required by regulatory authorities having jurisdiction
over the Plan, the options granted under it, and the Common Stock issued
pursuant to it.

          B.  No shares of Common Stock or other assets shall be issued or
delivered under this Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any securities exchange on which stock of the same class is then listed.

                                      28.

 
     VII. NO EMPLOYMENT/SERVICE RIGHTS

          Neither the action of the Corporation in establishing the Plan, nor
any action taken by the Plan Administrator hereunder, nor any provision of the
Plan shall be construed so as to grant any individual the right to remain in the
employ or service of the Corporation (or any parent or subsidiary corporation)
for any period of specific duration, and the Corporation (or any parent or
subsidiary corporation retaining the services of such individual) may terminate
such individual's employment or service at any time and for any reason, with or
without cause.

     VIII.  MISCELLANEOUS PROVISIONS

          A.  The right to acquire Common Stock or other assets under the Plan
may not be assigned, encumbered or otherwise transferred by any Optionee or
Participant.

          B.  The provisions of the Plan relating to the exercise of options and
the vesting of shares shall be governed by the laws of the State of California,
as such laws are applied to contracts entered into and performed in such State.

          C.  The provisions of the Plan shall inure to the benefit of, and be
binding upon, the Corporation and its successors or assigns, whether by
Corporate Transaction or otherwise, and the Participants and Optionees, the
legal representatives of their respective estates, their respective heirs or
legatees and their permitted assignees.

                                      29.
