     4.   Administration of the Plan.
          --------------------------

          (a)  Procedure.
               ---------

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

               (ii)   Administration With Respect to Directors and Officers
                      -----------------------------------------------------
          Subject to Section 16(b). With respect to Option grants made to
          ------------------------
          Employees who are also Officers or Directors subject to Section 16(b)
          of the Exchange Act, the Plan shall be administered by (A) the Board,
          if the Board may administer the Plan in compliance with the rules
          governing a plan intended to qualify as a discretionary plan under
          Rule 16b-3, or (B) a Committee designated by the Board to administer
          the Plan, which Committee shall be constituted to comply with the
          rules governing a plan intended to qualify as a discretionary plan
          under Rule 16b-3.  Once appointed, such Committee shall continue to
          serve in its designated capacity until otherwise directed by the
          Board.  From time to time the Board may increase the size of the
          Committee and appoint additional members, remove members (with or
          without cause) and substitute new members, fill vacancies (however
          caused), and remove all members of the Committee and thereafter
          directly administer the Plan, all to the extent permitted by the rules
          governing a plan intended to qualify as a discretionary plan under
          Rule 16b-3.  With respect to persons subject to Section 16 of the
          Exchange Act, transactions under the Plan are intended to comply with
          all applicable conditions of Rule 16b-3.  To the extent any provision
          of the Plan or action by the Administrator fails to so comply, it
          shall be deemed null and void, to the extent permitted by law and
          deemed advisable by the Administrator.

          neither Directors nor Officers of the Company, the Plan shall be
          administered by (A) the Board or (B) a Committee designated by the
          Board, which Committee shall be constituted to satisfy the legal
          requirements relating to the administration of stock option plans
          under applicable corporate and securities laws and the Code.  Once
          appointed, such Committee shall serve in its designated capacity until
          otherwise directed by the Board.  The Board may increase the size of
          the Committee and appoint additional members, remove members (with or
          without cause) and substitute new members, fill vacancies (however
          caused), and remove all members of the Committee and thereafter
          directly administer the Plan, all to the extent permitted by the legal
          requirements relating to the administration of stock option plans
          under state corporate and securities laws and the Code.

               (iv)     delivery of instructions to the Company to withhold from
the Shares that would otherwise be issued on the exercise that number of Shares
having a fair market value at the time of such exercise equal to the Option
exercise price;

               (v)      such other consideration and method of payment for the
issuance of Shares to the extent permitted by legal requirements relating to the
administration of stock option plans under applicable corporate and securities
laws and the Code; or

               (vi)     any combination of the foregoing methods of payment.

     If the fair market value of the number of whole Shares transferred or the
number of whole Shares surrendered is less than the total exercise price of the
Option, the shortfall must be made up in cash or by check. Notwithstanding the
foregoing provisions of this Section 8.(c), the consideration for Shares to be
issued pursuant to a Sale may not include, in whole or in part, the
consideration set forth in subsections (iii) and (iv) above.

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

          (a)  Procedure for Exercise, Rights as a Stockholder.  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 the Option Agreement and
Section 8.(c) of the Plan.  Each Optionee who exercises an Option shall, upon
notification of the amount due (if any) and prior to or concurrent with delivery
of the certificate representing the Shares, pay to the Company amounts necessary
to satisfy applicable federal, state and local tax withholding requirements.  An
Optionee must also provide a duly executed copy of any stock transfer agreement
then in effect and determined to be applicable by the Administrator.  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 stockholder shall exist with respect to the Optioned Stock
represented by such stock certificate, notwithstanding the 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 Employment or Consulting Relationship.  In the
               ----------------------------------------------------
event that an Optionee's Continuous Status as an Employee or Consultant
terminates (other than upon the Optionee's death or Disability), the Optionee
may exercise his or her Option, but only within such period of time as is
determined by the Administrator, and only to the extent that the Optionee was
entitled to exercise it at the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Notice of Grant).
In the case of an Incentive Stock Option, the Administrator shall determine such
period of time (in no event to exceed ninety (90) days from the date of
termination) when the Option is granted.  If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option with the
time specified by the Administrator, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

                                      -7-
<PAGE>

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

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

     10.  Nontransferability of Options.  An 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 and distribution, and may be exercised during
the lifetime of the Optionee only by the Optionee or, if incapacitated, by his
or her legal guardian or legal representative.

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

          (a)  Changes in Capitalization.  Subject to any required action by the
               -------------------------
stockholders, 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 Sales made or which have been returned to the Plan upon cancellation
or expiration of an Option, as well as 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)  Dissolution or Liquidation.  In the event of the proposed
               --------------------------
dissolution or liquidation of the Company, each outstanding 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 Board and give each Optionee the right to
exercise his or her Option as to all or any part of the Optioned Stock,
including Shares as to which the Option would not otherwise be exercisable.

          (c)  Merger or Asset Sale.  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, each outstanding 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.  If the Administrator

                                      -8-
<PAGE>

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 thirty (30) days from
the date of such notice or such shorter period as the Administrator may specify
in the notice, and the Option will terminate upon the expiration of such period.
For the purposes of this paragraph, the Option shall be considered assumed if,
following the merger or sale of assets, the Option confers the right to
purchase, for each Share of Optioned Stock subject to the Option immediately
prior to the merger or sale of assets, the consideration (whether stock, cash,
or other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such common stock of the consideration received in
the merger or sale of assets was not solely successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation and the
Optionee, provide for the consideration to be received upon the exercise of the
Option, for each Share of Optioned Stock subject to the Option, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

     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
Optionee 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;
provided, however, that if required to qualify the Plan under Rule 16b-3,
promulgated under Section 16 of the Exchange Act, no amendment shall be made
more than once every six (6) months that would change the amount, price or
timing of the option grants, other than to comport with changes in the Code or
the rules and regulations promulgated thereunder; and provided, further, that if
required to qualify the Plan under Rule 16b-3, no amendment shall be made
without the approval of the stockholders of the company in the manner described
in Section 17 of the Plan if the amendment would.

               (i)    increase the number of Shares subject to the Plan, other
than in connection with an adjustment under Section 11 of the Plan;

               (ii)   make a change in the designation of the class of
Employees, or Consultants eligible to be granted Options; or

               (iii)  if the Company has a class of equity security registered
under Section 12 of the Exchange Act at the time of such revision or amendment,
cause any material increase in the benefits, accruing to participants under the
Plan.

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

          (c)  Effect of Amendment or Termination.  Any such amendment or
               ----------------------------------
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Administrator, 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 or a Sale unless the exercise of such
Option or consummation of the Sale 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, applicable state
securities laws, the Exchange Act, the rules and regulations

                                      -9-
<PAGE>

promulgated thereunder, and the requirements of any stock exchange (including
NASDAQ) 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.

     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.

     16.  Liability of Company.
          --------------------

          (a)  Inability to Obtain Authority. 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.

          As a condition to the exercise of an Option or a Sale, the Company may
require the person exercising such Option or to whom Shares are being Sold to
represent and warrant at the time of any such exercise or Sale 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.

          (b)  Grants Exceeding Allotted Shares.  If the Optioned Stock covered
               --------------------------------
by an Option exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan without additional stockholder approval, such Option shall
be void with respect to such excess Optioned Stock, unless stockholder approval
of an amendment sufficiently increasing the number of Shares subject to the Plan
is timely obtained in accordance with Section 13 of the Plan.

     17.  Stockholder Approval.  Continuance of the Plan shall be subject to
          --------------------
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such stockholder approval shall be obtained
in the manner and to the degree required under applicable federal and state law.

     18.  Six Month Holding Period for Affiliates.  If the Company registers any
          ---------------------------------------
class of any equity security pursuant to Section 12 of the Exchange Act, then
from the effective date of such registration until six (6) months after the
termination of such registration (the Public Period), these limits will apply to
each Officer, Director and beneficial owner of ten percent (10%) or more of any
class of equity securities of the Company (Affiliates.) During the Public
Period, any Affiliate shall hold Shares Sold hereunder at least six (6) months
from the date of Sale.  During the Public Period, at least six (6) months must
elapse from the date of grant of an Option to an Affiliate to the date the
Affiliate disposes of the Shares acquired upon exercise of the Option, or (if
the Option is disposed of other than by exercise) to the date of disposition of
the Option itself.

remove members (with or without cause) and substitute new members, fill
vacancies (however caused), and remove all members of the Committee and
thereafter directly administer the Plan, all to the extent permitted by the
rules, if any, governing a plan intended to qualify as a discretionary plan
under Rule 16b-3. With respect to persons subject to Section 16 of the Exchange
Act, transactions under the Plan are intended to comply with all applicable
conditions of rule 16b-3. To the extent any provision of the Plan or action by
the Administrator fails to comply, it shall be deemed null and void, to the
extent permitted by law and deemed advisable by the Administrator.

               (iii)    Administration With Respect to Other Persons.  With
                        --------------------------------------------
respect to option grants made to Employees or Consultants who are neither
Directors nor Officers of the Company, the Plan shall be administered by (A) the
Board or (B) a Committee designated by the Board, which Committee shall be
constituted to satisfy the legal requirements relating to the administration of
stock option plans under applicable corporate and securities laws and the Code.

members of the Committee and thereafter directly administer the Plan, all to the
extent permitted by the Legal requirements relating to the administration of
stock option plans under state corporate and securities laws and the Code.

<PAGE>

          (b)  ISO Limitation.  To the extent that the aggregate Fair Market
               --------------
Value:  (i) of Shares subject to an Optionee's Incentive Stock Options granted
by the Company, any Parent or Subsidiary, which (ii) become exercisable for the
first time during any calendar year (under all plans of the Company or any
Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonqualified Stock Options.  For purposes of this Section 5.(b), Incentive Stock
Options shall be taken into account in the order in which they were granted, and
the Fair Market Value of the Shares shall be determined as of the time of grant.

          (c)  Section 5.(b) Limitations.  Section 5.(b) of the Plan shall apply
               -------------------------
only to an Incentive Stock Option evidenced by an Option Agreement which sets
forth the intention of the Company and the Optionee that such Option shall
qualify as an Incentive Stock Option.  Section 5.(b) of the Plan shall not apply
to any Option evidenced by an Option Agreement which sets forth the intention of
the Company and the Optionee that such Option shall be a Nonqualified Stock
Option.

          (d)  No Right to Continued Employment.  The Plan shall not confer upon
               --------------------------------
any Optionee any right with respect to continuation of employment or consulting

Company, Options to purchase more than 75,000 Shares.

               (ii)   In connection with his or her initial employment, an
Employee may be granted Options to purchase up to an additional 75,000 Shares
which shall not count against the limit set forth in subsection (i) above.

               (iii)  The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11.

               (iv)   If an Option is canceled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 11), the canceled Option shall be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

     6.   Term of Plan.  The Plan shall become effective upon the earlier to
          ------------
occur of its adoption by the Board or its approval by the shareholders of the

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

     8.   Exercise/Purchase Price and Consideration.
          -----------------------------------------

          (a)  Exercise/Purchase Price.  The per-Share exercise/purchase price
               -----------------------
for the Shares to be issued pursuant to exercise of an Option or a Sale shall be
such price as is determined by the Administrator, but shall be subject to the
following:

               (i)    In the case of an Incentive Stock Option

                      (A)   granted to an Employee who, at the time of the grant
of such Incentive Stock Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the

                                      -5-
<PAGE>

Company or any Parent or Subsidiary, the per Share exercise price shall be no
less than one hundred ten percent (110%)of the Fair Market Value per Share on
the date of the grant.

                      (B)   granted to any other Employee, the per Share

Market Value per Share on the date of grant.

               (ii)   In the case of a Nonqualified Stock Option or Sale, the
per Share exercise/purchase price shall be determined by the Administrator.

               (iii)  Any determination to establish an Option exercise price or
effect a Sale of Common Stock at less than Fair Market Value on the date of the
Option grant or authorization of Sale shall be accompanied by an express finding
by the Administrator specifying that the sale is in the best interest of the
Company, and specifying both the Fair Market Value and the Option exercise price
or Sale price of the Common Stock.

          (b)  Consideration. The consideration, to be paid for the Shares to be
               -------------
issued upon exercise of an Option or pursuant to a Sale, including the method of
payment, shall be determined by the Administrator.  In the case of an Incentive
Stock Option, the Administrator shall determine the acceptable form of
consideration at the time of grant. Such consideration may consist of:

               (i)    cash;

               (ii)   check;

               (iii)  promissory note;

               (iv)   transfer to the Company of Shares which

                      (A)   in the case of Shares acquired upon exercise of an
Option, have been owned by the Optionee for more than six months on the date of
surrender, and

                      (B)   have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Shares to be acquired;

               (v)    delivery of a properly executed exercise notice together
with irrevocable instructions to a broker to promptly deliver to the Company the
amount of sale or loan proceeds required to pay the exercise price;

               (vi)   such other consideration and method of payment for the
issuance of Shares to the extent permitted by legal requirements relating to the
administration of stock option plans and issuances of capital stock under
applicable corporate and securities laws and the Code; or

               (vii)  any combination of the foregoing methods of payment.

     If the Fair Market Value of the number of whole Shares transferred or the
number of whole Shares surrendered is less than the total exercise price of the
Option, the shortfall must be made up in cash or by check.  Notwithstanding the
foregoing provisions of this Section 8.(b), the consideration for Shares to  be
issued pursuant to a Sale may not include, in whole or in part, the
consideration set forth in subsections (iv) and (v) above.

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

          (a)  Procedure for Exercise, a Rights as 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

                                      -6-
<PAGE>

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 the Option Agreement and
Section 8.(b) of the Plan. Each Optionee who exercises an Option shall, upon
notification of the amount due (if any) and prior to or concurrent with delivery
of the certificate representing the Shares, pay to the Company amounts necessary
to satisfy applicable federal, state and local tax withholding requirements. An
Optionee must also provide a duly executed copy of any stock transfer agreement
then in effect and determined to be applicable by the Administrator. Until the
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 represented by such
stock certificate, notwithstanding the 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 Employment or Consulting Relationship.  In the
               ----------------------------------------------------
event that an Optionee's Continuous Status as  an Employee or Consultant
terminates (other than upon the Optionee's death or Disability), the Optionee
may exercise his or her Option, but only within such period of time as is
determined by the Administrator, and only to the extent that the Optionee was
entitled to exercise it at the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Notice of Grant).
In the case of an Incentive Stock Option, the Administrator shall determine such
period of time (in no event to exceed three (3) months from the date of
termination) when the Option is granted.  If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option with,
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

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

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

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

          (f)  Buyout Provisions. The Administrator may at any time offer to buy
               -----------------
out, in whole or in part, for a payment in cash or Shares, an Option previously
granted, based on such terms and conditions as the Administrator shall establish
and communicate to the Optionee at the time, that such offer is made.

     10.  Nontransferability of Options.  Except as otherwise specifically
          -----------------------------
provided in the Option Agreement an 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 and distribution, and may be exercised during the lifetime
of the Optionee only by the Optionee or, if incapacitated, by his or her legal
guardian or legal representative.

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

          (a)  Changes in Capitalization:  Subject to any required action by the
               -------------------------
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and 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 Sales made or which have been returned to the Plan upon cancellation
or expiration of an Option, as well as 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 an 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)  Dissolution or Liquidation.  In the event of the proposed
               --------------------------
dissolution or liquidation of the Company, each outstanding 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 Board and give each Optionee the right to
exercise his or her Option as to all or any part of the Optioned Stock,
including Shares as to which the Option would not otherwise be exercisable.

          (c)  Merger or Asset Sale.  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, each outstanding Option shalt 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.  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 thirty, (30) days from the date of
such notice or such shorter period as the Administrator may specify in the
notice, and the Option will terminate upon the expiration of such period.  For
the purposes of this paragraph, the Option shall be considered assumed if,
following the merger or sale of assets, the Option confers the right to
purchase, for each Share of Optioned Stock subject to the Option immediately
prior to the merger or sale of assets, the consideration (whether stock, cash,
or other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets was not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation and the
Optionee, provide for the consideration to be received upon the exercise of the
Option, for each Share of Optioned Stock subject to the Option, to be solely
common stock of the successor corporation or its Parent equal in Fair Market
Value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

     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
Optionee 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)  Shareholder Approval.  The Company shall obtain shareholder
               --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Rule 16b-3 or with Section 422 of the Code (or any successor rule or
statute or other applicable law, rule or regulation, including the requirements
of any exchange or

                                      -8-
<PAGE>

quotation system on which the Common Stock is listed or quoted). Such
shareholder approval, if required, shall be obtained, in such a manner and to
such a degree as is required by the applicable law, rule or regulation.

          (c)  Effect of Amendment or Termination.  Any such amendment or
               ----------------------------------
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Administrator, 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 or a Sale unless the exercise of such
Option or consummation of the Sale 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, applicable state
securities laws, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange (including NASDAQ) 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.

     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.

     16.  Liability of Company.
          --------------------

          (a)  Inability to Obtain Authority. 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.

          As a condition to the exercise of an Option or a Sale, the Company may
require the person exercising such Option or to whom Shares are being Sold to
represent and warrant at the time of any such exercise or Sale 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.

          (b)  Grants Exceeding Allotted Shares.  If the Optioned Stock covered
               --------------------------------
by an option exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan without additional shareholder approval, such Option shall
be void with respect to such excess Optioned Stock, unless shareholder approval
of an amendment sufficiently increasing the number of Shares subject to the Plan
is timely obtained in accordance with Section 13 of the Plan.

     17.  Shareholder Approval.  Continuance of the Plan shall be subject to
          --------------------
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such shareholder approval shall be obtained
