          (b) Powers of the Administrator.  Subject to the provisions of the
              ---------------------------
Plan, and in the case of a Committee, the specific duties delegated by, or
limitations of authority imposed by, the Board to or on such Committee, the

acceleration or waiver of forfeiture restrictions regarding any Option and/or
the shares of Common Stock relating thereto, based in each case on such

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

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

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

                                      -4-

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

          (a) Recipients of Grants.  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) Type of Option.  Each Option shall be designated in the written
              --------------
option agreement as a Nonstatutory Stock Option.

          (c) No Employment Rights.  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
         ------------
Board of Directors.  It shall continue in effect for a term of ten (10) years
unless sooner terminated under Section 15 of the Plan.

     7.  Term of Option. The term of each Nonstatutory Stock Option shall be ten
         --------------
(10) years from the date of grant thereof or such shorter term as may be
provided in the Nonstatutory Stock Option Agreement.

     8.  Exercise Price and Consideration.
         --------------------------------

          (a) The per Share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the
Administrator, but shall be no less than 85% of the fair market value per Share
on the date of grant.

          (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator and 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) authorization from
the Company to retain from the total number of Shares as to which the Option is
exercised that number of Shares having a Fair Market Value on the date of
exercise equal to the exercise price for the total number of Shares as to which
the Option is exercised; (6) 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,
(7) any combination of such methods of payment, or (8) such other consideration
and method of payment for the issuance of Shares permitted under Applicable
Laws.  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.

                                      -5-
<PAGE>

     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 8(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 13 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 three (3) months (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
              ----------------------
9(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 six
(6) months (or such other period of time not exceeding twelve (12) months as is
determined by the Administrator) 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

                                      -6-
<PAGE>

(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:

             (i) during the term of the Option, the Option may be exercised,
at any time within six (6) 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 that would have accrued had the
Optionee continued living and remained in Continuous Status as an Employee or
Consultant six (6) months (or such other period of time as is determined by
the Administrator as provided above) after the date of death.

             (ii) within thirty (30) days (or such other period of time not
exceeding three (3) months as is determined by the Administrator) after the
termination of Continuous Status as an Employee or Consultant, the Option may
be exercised, at any time within six (6) 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 that had accrued at the date of
termination.

     10.  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.

     11.  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").

                                      -7-
<PAGE>

          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.

     12.  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.  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 12.

     13.  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 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,

                                      -8-
<PAGE>

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 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 the Administrator determines, in the exercise of
its sole discretion and in lieu of such assumption or substitution, that the
Optionee shall 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 or the Administrator determines to terminate the unvested and
unexercised option. If the Administrator makes an Option 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 thirty (30) days from the date of such notice, and
the Option will terminate upon the expiration of such period.

     14.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------
all purposes, be the date on which the Administrator makes the determination
granting such Option or such other date as is determined by the Administrator.
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.

     15.  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.

                                      -9-
<PAGE>

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

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