appoint additional members thereof, remove members (with or without cause) and
appoint new members in substitution therefor, fill vacancies (however caused)
and remove all members of a Committee and thereafter directly administer the
Plan, all to the extent permitted by the Applicable Laws.

             ---------------------------

represented by each Option;

               (v)   to interpret the Plan;

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

               (vii) to determine the terms and provisions of each Option
granted (which need not be identical) and, with the consent of the holder
thereof, modify or amend each Option;

               (viii) to accelerate or defer (with the consent of the Optionee)

               (ix)   to authorize any person to execute on behalf of the

               (x)    to make all other determinations deemed necessary or
advisable for the administration of the Plan.

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

     5.  Eligibility.
         ----------- 

          (a) Options may be granted only to Employees and Consultants. An
Employee or Consultant who has been granted an Option may, if Optionee is
otherwise eligible, be granted an additional Option or Options.

          (b) Each Option shall be designated in the written option agreement as
a Nonstatutory Stock Option.

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

     6.  Term of Plan.  The Plan shall become effective upon its adoption by the
         ------------

on the date of grant.

          (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator and may consist entirely of (1) cash, (2) check, (3)
promissory note, (4) other Shares of Common Stock which (i) either have been
owned by the Optionee for more than six (6) months on the date of surrender or
were not acquired, directly or indirectly, from the Company, and (ii) have a
fair market value on the date of surrender equal to the aggregate exercise price
of the Shares as to which said Option shall be exercised, (5) delivery of a
properly executed exercise notice together with irrevocable instructions to a
broker to deliver promptly to the Company the amount of sale or loan proceeds
required to pay the exercise price, or (6) any combination of such methods of
payment.  In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

                                      -3-

     9.  Exercise of Option.
         ------------------ 

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

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

          An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 9(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

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

          (b) Termination of Status as an Employee or Consultant.  In the event
              --------------------------------------------------               
of termination of an Optionee's Continuous Status as an Employee or Consultant,
such Optionee may, but only within thirty (30) days (or such other period of
time, not exceeding six (6) months, as is determined by the Administrator) after
the date of such termination (but in no event later than the date of expiration
of the term of such Option as set forth in the Option Agreement), exercise
Optionee's Option to the extent that Optionee was entitled to exercise it at the
date of such termination.  To the extent that Optionee was not entitled to
exercise the Option at the date of such termination, or if Optionee does not
exercise such Option (which Optionee was entitled to exercise) within the time
specified herein, the Option shall terminate.

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

          (d) Death of Optionee.  In the event of termination of an Optionee's
              -----------------                                               
Continuance Status as an Employee or Consultant as a result of the death of an
Optionee, the Option may be exercised, at any time within twelve (12) months
following the date of death (but in no event later than the date of expiration
of the term of such Option as set forth in the Option Agreement), by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise the
Option at the date of death.  To the extent that Optionee was not entitled to
exercise the Option at the date of death, or if Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
shall terminate.

     10.  Non-Transferability of Options.  The Option may not be sold, pledged,
          ------------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution; provided, that the Administrator
                                                --------                        
may in its discretion grant transferable Nonstatutory Stock Options pursuant to
option agreements specifying (i) the manner in which such Nonstatutory Stock
Options are transferable and (ii) that any such transfer shall be subject to the
Applicable Laws.  The designation of a beneficiary by an Optionee will not
constitute a transfer.  An Option may be exercised, during the lifetime of the
Optionee, only by the Optionee or a transferee permitted by this Section 11.

     11.  Adjustments Upon Changes in Capitalization or Merger.
          ---------------------------------------------------- 

          (a) Adjustments.  Subject to any required action by the shareholders
              -----------                                                     
of the Company, the number of shares of Common Stock covered by each outstanding
Option, and the number of shares of Common Stock which have been authorized for
issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon 

                                      -4-
<PAGE>
 
cancellation or expiration of an Option, and the price per share of Common Stock
covered by each such outstanding Option, shall be proportionately adjusted for
any increase or decrease in the number of issued shares of Common Stock
resulting from a stock split, reverse stock split, stock dividend, combination
or reclassification of the Common Stock, or any other increase or decrease in
the number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

          (b) Corporate Transactions.  In the event of the proposed dissolution
              ----------------------                                           
or liquidation of the Company, the Option will terminate immediately prior to
the consummation of such proposed action, unless otherwise provided by the
Administrator.  The Administrator may, in the exercise of its sole discretion in
such instances, declare that any Option shall terminate as of a date fixed by
the Administrator and give each Optionee the right to exercise Optionee's Option
as to all or any part of the Optioned Stock, including Shares as to which the
Option would not otherwise be exercisable.  In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, the Option shall be assumed or an
equivalent option shall be substituted by such successor corporation or a parent
or subsidiary of such successor corporation, unless such successor corporation
does not agree to assume the Option or to substitute an equivalent option, in
which case the Administrator shall, in lieu of such assumption or substitution,
provide for the Optionee to have the right to exercise the Option as to all of
the Optioned Stock, including Shares as to which the Option would not otherwise
be exercisable.  If the Administrator makes an Option fully exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee that the Option shall be fully
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option will terminate upon the expiration of such period.

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

     13.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a) Amendment and Termination.  The Board may amend or terminate the
              -------------------------                                       
Plan from time to time in such respects as the Board may deem advisable

          (b) Effect of Amendment or Termination.  Any such amendment or
              ----------------------------------                        
termination of the Plan shall not adversely affect Options already granted
(except to the extent contemplated by such Options) and such Options shall
remain in full force and effect, unless mutually agreed otherwise between the
Optionee and the Board (or other body then administering the Plan), which
agreement must be in writing and signed by the Optionee and the Company.

     14.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

     As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

     15.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     16.  Option Agreement.  Options shall be evidenced by written option
          ----------------                                               
agreements in such form as the Administrator shall approve.

     17.  Information to Optionees.  The Company shall provide to each Optionee
          ------------------------                                             
upon request, during the period for which such Optionee has one or more Options
outstanding, copies of all annual reports and other information which are
provided to all shareholders of the Company.

     18.  Withholding Taxes.  As a condition to the exercise of Options granted
          -----------------                                                    
hereunder, the Optionee shall make such arrangements as the Administrator may
require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection with the exercise, receipt or
vesting of such Option.  The Company shall not be required to issue any Shares
under the Plan until such obligations are satisfied.

     19.  Stock Withholding to Satisfy Withholding Tax Obligations.  At the
          --------------------------------------------------------         
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods:  (a) by cash payment, or (b) out of Optionee's current
compensation, or (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than Optionee's marginal tax rate times the
ordinary income recognized, or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option that number of Shares having
a fair market value equal to the amount required to be withheld.  For this
purpose, the fair market value of the Shares to be withheld shall be determined
on the date that the amount of tax to be withheld is to be determined (the "Tax
Date").

          All elections by an Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a) the election must be made on or prior to the applicable Tax Date;

          (b) once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made; and

          (c) all elections shall be subject to the consent or disapproval of
the Administrator.

          In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.
