Value of a share of Stock shall be the closing price of a share of Stock (or

in the Participating Company for which the Optionee renders such Service,
provided that there is no interruption or termination of the Optionee's
Service. Furthermore, the Optionee's Service with the Participating Company

days, on the one hundred eighty-first (181st) day following the commencement
of such leave any Incentive Stock Option held by the Optionee shall cease to
be treated as an Incentive Stock Option and instead shall be treated
thereafter as a Nonstatutory Stock Option unless the Optionee's right to
return to Service with the Participating Company Group is guaranteed by
statute or contract. Notwithstanding the foregoing, unless otherwise
designated by the Company or required by law, a leave of absence shall not be
treated as Service for purposes of determining the Optionee's Vested Shares.
The Optionee's Service shall be deemed to have terminated either upon an
actual termination of Service or upon the corporation for which the Optionee
performs Service ceasing to be a Participating Company. Subject to the
foregoing, the Company, in its sole discretion, shall determine whether the
Optionee's Service has terminated and the effective date of such termination.

                                       3

<PAGE>

thereafter the remaining shares will become Vested Shares in substantially
equal installments at the periodic rate set forth in the Notice, with the
last such installment vesting on the last "Full Vest" date set forth in the
Notice.

              1.2 CONSTRUCTION. Captions and titles contained herein are for
convenience only and shall not affect the meaning or interpretation of any
provision of this Option Agreement. Except when otherwise indicated by the
context, the singular shall include the plural and the plural shall include
the singular. Use of the term "or" is not intended to be exclusive, unless
the context clearly requires otherwise.

         2. TAX STATUS OF OPTION.

              2.1 TAX STATUS OF OPTION. This Option is intended to be an
incentive stock option within the meaning of Section 422(b) of the Code, but
the Company does not represent or warrant that this Option qualifies as such.
The Optionee should consult with the Optionee's own tax advisor regarding the
tax effects of this Option and the requirements necessary to obtain favorable
income tax treatment under Section 422 of the Code, including, but not
limited to, holding period requirements. (NOTE TO OPTIONEE: If the Option is
exercised more than three (3) months after the date on which you cease to be
an Employee (other than by reason of your death or permanent and total
disability as defined in Section 22(e)(3) of the Code), the Option will be
treated as a nonstatutory stock option and not as an incentive stock option
to the extent required by Section 422 of the Code.)

              2.2 FAIR MARKET VALUE LIMITATION. To the extent that the Option
(together with all incentive stock options granted to the Optionee under all
stock option plans of the Participating Company Group, including the Plan)
becomes exercisable for the first time during any calendar year for shares
having a Fair Market Value greater than One Hundred Thousand Dollars
($100,000), the portion of such options which exceeds such amount will be
treated as nonstatutory stock options. For purposes of this Section 2.2,
options designated as incentive stock options are taken into account in the
order in which they were granted, and the Fair Market Value of stock is
determined as of the time the option with respect to such stock is granted.
If the Code is amended to provide for a different limitation from that set
forth in this Section 2.2, such different limitation shall be deemed
incorporated herein effective as of the date required or permitted by such
amendment to the Code. If the Option is treated as an incentive stock option
in part and as a nonstatutory stock option in part by reason of the
limitation set forth in this Section 2.2, the Optionee may designate which
portion of such Option the Optionee is exercising. In the absence of such
designation, the Optionee shall be deemed to have exercised the incentive
stock option portion of the Option first. Separate certificates representing
each such portion shall be issued upon the exercise of the Option. (NOTE TO
OPTIONEE: If the aggregate Exercise Price of the Option (that is, the
Exercise Price multiplied by the Number of Option Shares) plus the aggregate
exercise price of any other incentive stock options you hold (whether granted
pursuant to the Plan or any other stock option plan of the Participating
Company Group) is greater than $100,000, you should contact the Chief
Financial Officer of the Company to ascertain whether the entire Option
qualifies as an incentive stock option.)

         3. ADMINISTRATION.

              All questions of interpretation concerning this Option
Agreement shall be determined by the Board. All determinations by the Board
shall be final and binding upon all persons having an interest in the Option.
Any officer of a Participating Company shall have the authority to act on
behalf of the Company with respect to any matter, right, obligation, or
election which is the responsibility of or which is allocated to the Company
herein, provided the officer has apparent authority with respect to such
matter, right, obligation, or election.

         4. EXERCISE OF THE OPTION.

              4.1 RIGHT TO EXERCISE. Except as otherwise provided herein, the
Option shall be exercisable prior to the termination of the Option (as
provided in Section 6) in an amount not to exceed that portion of the Number
of Option Shares which have become Vested Shares less the number of shares
previously acquired upon exercise of the Option. Notwithstanding the
foregoing, the Option may not be exercised as to less than ten (10) shares at
any one time or, if less, the number of shares then remaining exercisable
pursuant to the Option. In no event shall the Option be exercisable for more
shares than the Number of Option Shares.

              4.2 METHOD OF EXERCISE. Exercise of the Option shall be by
written notice to the Company which must state the election to exercise the
Option, the number of whole shares of Stock for which the Option is being
exercised and such other representations and agreements as to the Optionee's
investment intent with respect to such shares as may be required pursuant to
the provisions of this Option Agreement. The written notice must be signed by
the Optionee and must be delivered to the Chief Financial Officer of the
Company, or other authorized representative of the Participating Company
Group, prior to the termination of the Option as set forth in Section 6,
accompanied by full payment of the aggregate Exercise Price for the number of
shares of Stock being purchased and the tax withholding obligations, if any,
as provided in Section 4.4. The Option shall be deemed to be exercised upon
receipt by the Company of such written notice, the aggregate Exercise Price,
and tax withholding obligations, if any.

                  4.3 PAYMENT OF EXERCISE PRICE.

                       (a) FORMS OF CONSIDERATION AUTHORIZED. Except as
otherwise provided below, payment of the aggregate Exercise Price for the
number of shares of Stock for which the Option is being exercised shall be
made (i) in cash or cash equivalent, (ii) by tender to the Company of whole
shares of Stock owned by the Optionee having a Fair Market Value (as
determined by the Company without regard to any restrictions on
transferability applicable to such stock by reason of federal or state
securities laws or agreements with an underwriter for the Company) not less
than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as
defined in Section 4.3(b)(ii), or (iv) by any combination of the foregoing.

                                       5

                       (b) LIMITATIONS ON FORMS OF CONSIDERATION.

                                (i) TENDER OF STOCK.  Notwithstanding the
foregoing, the Option may not be exercised by tender to the Company of shares
of Stock to the extent such tender of Stock would constitute a violation of
the provisions of any law, regulation or agreement restricting the redemption
of the Company's stock. The Option may not be exercised by tender to the
Company of shares of Stock unless such shares either have been owned by the
Optionee for more than six (6) months or were not acquired, directly or
indirectly, from the Company.

                                (ii) CASHLESS EXERCISE.  A "CASHLESS
EXERCISE" means the assignment in a form acceptable to the Company of the
proceeds of a sale or loan with respect to some or all of the shares of Stock
acquired upon the exercise of the Option pursuant to a program or procedure
approved by the Company (including, without limitation, through an exercise
complying with the provisions of Regulation T as promulgated from time to
time by the Board of Governors of the Federal Reserve System). The Company
reserves, at any and all times, the right, in the Company's sole and absolute
discretion, to decline to approve or terminate any such program or procedure.

              4.4 TAX WITHHOLDING. At the time the Option is exercised, in
whole or in part, or at any time thereafter as requested by the Company, the
Optionee hereby authorizes withholding from payroll and any other amounts
payable to the Optionee, and otherwise agrees to make adequate provision for
(including by means of a Cashless Exercise to the extent permitted by the
Company), any sums required to satisfy the federal, state, local and foreign
tax withholding obligations of the Participating Company Group, if any, which
arise in connection with the Option, including, without limitation,
obligations arising upon (i) the exercise, in whole or in part, of the
Option, (ii) the transfer, in whole or in part, of any shares acquired upon
exercise of the Option, (iii) the operation of any law or regulation
providing for the imputation of interest, or (iv) the lapsing of any
restriction with respect to any shares acquired upon exercise of the Option.
The Optionee is cautioned that the Option is not exercisable unless the tax
withholding obligations of the Participating Company Group are satisfied.
Accordingly, the Optionee may not be able to exercise the Option when desired
even though the Option is vested, and the Company shall have no obligation to
issue a certificate for such shares.

              4.5 CERTIFICATE REGISTRATION. Except in the event the Exercise
Price is paid by means of a Cashless Exercise, the certificate for the shares
as to which the Option is exercised shall be registered in the name of the
Optionee, or, if applicable, in the names of the heirs of the Optionee.

              4.6 RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES.
The grant of the Option and the issuance of shares of Stock upon exercise of
the Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may
not be exercised if the issuance of shares of Stock upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, the
Option may not be exercised unless (i) a registration

                                       6

<PAGE>

statement under the Securities Act shall at the time of exercise of the
Option be in effect with respect to the shares issuable upon exercise of the
Option or (ii) in the opinion of legal counsel to the Company, the shares
issuable upon exercise of the Option may be issued in accordance with the
terms of an applicable exemption from the registration requirements of the
Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE
EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE
OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE
OPTION IS VESTED. Questions concerning this restriction should be directed to
the Chief Financial Officer of the Company. The inability of the Company to
obtain from any regulatory body having jurisdiction the authority, if any,
deemed by the Company's legal counsel to be necessary to the lawful issuance
and sale of any shares subject to the Option 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 the Option, the Company may require the Optionee to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance
with any applicable law or regulation and to make any representation or
warranty with respect thereto as may be requested by the Company.

              4.7 FRACTIONAL SHARES. The Company shall not be required to
issue fractional shares upon the exercise of the Option.

         5. NONTRANSFERABILITY OF THE OPTION.

              The Option may be exercised during the lifetime of the Optionee
only by the Optionee or the Optionee's guardian or legal representative and
may not be assigned or transferred in any manner except by will or by the
laws of descent and distribution. Following the death of the Optionee, the
Option, to the extent provided in Section 7, may be exercised by the
Optionee's legal representative or by any person empowered to do so under the
deceased Optionee's will or under the then applicable laws of descent and
distribution.

         6. TERMINATION OF THE OPTION.

              The Option shall terminate and may no longer be exercised on
the first to occur of (a) the Option Expiration Date, (b) the last date for
exercising the Option following termination of the Optionee's Service as
described in Section 7, or (c) a Change in Control to the extent provided in
Section 8.

         7. EFFECT OF TERMINATION OF SERVICE.

              7.1 OPTION EXERCISABILITY.

                       (a) DISABILITY.  If the Optionee's Service with the
Participating Company Group is terminated because of the Disability of the
Optionee, the Option, to the extent unexercised and exercisable on the date
on which the Optionee's Service terminated, may be exercised by the Optionee
(or the Optionee's guardian or legal representative) at any time prior to

                                       7

<PAGE>

the expiration of three (3) months after the date on which the Optionee's
Service terminated, but in any event no later than the Option Expiration Date.

                       (b) DEATH.  If the Optionee's Service with the
Participating Company Group is terminated because of the death of the
Optionee, the Option, to the extent unexercised and exercisable on the date
on which the Optionee's Service terminated, may be exercised by the
Optionee's legal representative or other person who acquired the right to
exercise the Option by reason of the Optionee's death at any time prior to
the expiration of six (6) months after the date on which the Optionee's
Service terminated, but in any event no later than the Option Expiration
Date. The Optionee's Service shall be deemed to have terminated on account of
death if the Optionee dies within three (3) months after the Optionee's
termination of Service.

                       (c) TERMINATION AFTER A CHANGE IN CONTROL.  If the
Optionee's Service with the Participating Company Group ceases as a result of
Termination After a Change in Control (as defined below), the (i) the Option,
to the extent unexercised and exercisable on the date on which the Optionee's
Service terminated, may be exercised by the Optionee (or the Optionee's
guardian or legal representative) at any time prior to the expiration of six
(6) months after the date on which the Optionee's Service terminated, but in
any event no later than the Option Expiration Date, and (ii) the Option shall
become immediately exercisable and vested in full as of the date on which the
Optionee's Service terminated. Notwithstanding the foregoing, if it is
determined that the provisions or operation of this Section 7.1(c) would
preclude treatment of a Change in Control as a "pooling-of-interests" for
accounting purposes and provided further that in the absence of the preceding
sentence such Change in Control would be treated as a "pooling-of-interests"
for accounting purposes, then this Section 7.1(c) shall be void AB INITIO,
and the vesting and exercisability of the Option shall be determined under
any other applicable provision of the Option Agreement.

                       (d) OTHER TERMINATION OF SERVICE.  If the Optionee's
Service with the Participating Company Group terminates for any reason,
except Disability, death or Termination After a Change in Control, the
Option, to the extent unexercised and exercisable by the Optionee on the date
on which the Optionee's Service terminated, may be exercised by the Optionee
within thirty (30) days (or such other longer period of time as determined by
the Board, in its discretion) after the date on which the Optionee's Service
terminated, but in any event no later than the Option Expiration Date.

              7.2 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods
set forth in Section 7.1 is prevented by the provisions of Section 4.6, the
Option shall remain exercisable until thirty (30) days after the date the
Optionee is notified by the Company that the Option is exercisable, but in
any event no later than the Option Expiration Date.

              7.3 EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods
set forth in Section 7.1 of shares acquired upon the exercise of the Option
would subject the Optionee to suit under Section 16(b) of the Exchange Act,
the Option shall remain exercisable until the earliest to occur of (i) the
tenth

                                       8

<PAGE>

(10th) day following the date on which a sale of such shares by the Optionee
would no longer be subject to such suit, (ii) the one hundred and ninetieth
(190th) day after the Optionee's termination of Service, or (iii) the Option
Expiration Date.

Reason (as defined below) from all capacities in which the Optionee is then
rendering Service to the Participating Company Group within a reasonable
period of time following the event constituting Good Reason.

Notwithstanding any provision herein to the contrary, Termination After a Change
in Control shall not include any termination of the Optionee's Service with the
Participating Company Group which (1) is for Cause (as defined below); (2) is a
result of the Optionee's death or disability; (3) is a result of the Optionee's
voluntary termination of Service other than for Good Reason; or (4) occurs prior
to the effectiveness of a Change in Control.

                       (b) "CAUSE" shall mean any of the following: (i) the

Participating Company immediately prior to the date of the Change in Control;

                                (ii) without the Optionee's express written
consent, the relocation of the principal place of the Optionee's Service to a

                                (iii) any failure by a Participating Company
to pay, or any material reduction by Participating Company of, (1) the
Optionee's base salary in effect immediately prior to the date of the Change

concurrently made for all other employees of the Participating Company Group
with responsibilities, organizational level and title comparable to the
Optionee's), or (2) the Optionee's bonus compensation, if any, in effect
immediately prior to the date of the Change in Control (subject to applicable

compensation earned by the Optionee); or

                                (iv) any failure by a Participating Company

on terms no less favorable than those in effect for the benefit of any
employee group which customarily includes a person holding the employment
position or a comparable position with the Participating Company then held by
the Optionee, in any benefit or compensation plans and programs, including,
but not limited to, the Participating Company's life, disability, health,
dental, medical, savings, profit sharing, stock purchase and retirement
plans, if any, in which the Optionee was participating immediately prior to
the date of the Change in Control, or their equivalent, or (2) provide the
Optionee with all other fringe benefits (or their equivalent) from time to
time in effect for the benefit of any employee group which customarily
includes a person holding the employment position or a comparable position
with the Participating Company then held by the Optionee.

         8. CHANGE IN CONTROL.

              8.1 DEFINITIONS.

                       (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to
have occurred if any of the following occurs with respect to the Company: (i)
the direct or indirect sale or exchange in a single or series of related
transactions by the stockholders of the Company of more than fifty percent
(50%) of the voting stock of the Company; (ii) a merger or consolidation in
which the Company is a party; (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or (iv) a liquidation or
dissolution of the Company.

                       (b) A "CHANGE IN CONTROL" shall mean an Ownership
Change Event or a series of related Ownership Change Events (collectively,
the "TRANSACTION") wherein the stockholders of the Company immediately before
the Transaction do not retain immediately after the Transaction, in
substantially the same proportions as their ownership of shares of the
Company's voting stock immediately before the Transaction, direct or indirect
beneficial ownership of more than fifty percent (50%) of the total combined
voting power of the outstanding voting stock of the Company or the
corporation or corporations to which the assets of the Company were
transferred (the "TRANSFEREE CORPORATION(S)"), as the case may be. For

                                       10

<PAGE>

purposes of the preceding sentence, indirect beneficial ownership shall
include, without limitation, an interest resulting from ownership of the
voting stock of one or more corporations which, as a result of the
Transaction, own the Company or the Transferee Corporation(s), as the case
may be, either directly or through one or more subsidiary corporations. The
Board shall have the right to determine whether multiple sales or exchanges
of the voting stock of the Company or multiple Ownership Change Events are
related, and its determination shall be final, binding and conclusive.

              8.2 EFFECT OF CHANGE IN CONTROL ON OPTION. In the event of a
Change in Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), shall either assume the Company's rights and obligations under
the Option or substitute for the Option a substantially equivalent option for
the Acquiring Corporation's stock. In the event the Acquiring Corporation
elects not to assume the Company's rights and obligations under the Option or
substitute for the Option in connection with the Change in Control, and
provided that the Optionee's Service has not terminated prior to such date,
any unexercised portion of the Option shall be immediately exercisable and
vested in full as of the date ten (10) days prior to the date of the Change
in Control. Any exercise of the Option that was permissible solely by reason
of this Section 8.2 shall be conditioned upon the consummation of the Change
in Control. The Option shall terminate and cease to be outstanding effective
as of the date of the Change in Control to the extent that the Option is
neither assumed or substituted for by the Acquiring Corporation in connection
with the Change in Control nor exercised as of the date of the Change in
Control. Notwithstanding the foregoing, if the corporation the stock of which
is subject to the Option immediately prior to an Ownership Change Event
described in Section 8.1(a)(i) constituting a Change in Control is the
surviving or continuing corporation and immediately after such Ownership
Change Event less than fifty percent (50%) of the total combined voting power
of its voting stock is held by another corporation or by other corporations
that are members of an affiliated group within the meaning of Section 1504(a)
of the Code without regard to the provisions of Section 1504(b) of the Code,
the Option shall not terminate unless the Board otherwise provides in its
sole discretion.

              8.3 FAIR MARKET VALUE LIMITATION. Should the exercisability of
this Option be accelerated in connection with a Change in Control in
accordance with Section 7.1(c) or 8.2, then to the extent that the aggregate
Fair Market Value of the shares of Stock with respect to which the Optionee
may exercise the Option for the first time during the calendar year of such
acceleration, when added to the aggregate Fair Market Value of the shares
subject to any other options designated as incentive stock options granted to
the Optionee under all stock option plans of the Participating Company Group
prior to the Date of Option Grant with respect to which such options are
exercisable for the first time during the same calendar year, exceeds One
Hundred Thousand Dollars ($100,000) (or such other limit, if any, imposed by
Section 422 of the Code), the portion of the Option which exceeds such amount
shall be treated as a nonstatutory stock option. For purposes of the
preceding sentence, options designated as incentive stock options shall be
taken into account in the order in which they were granted, and the Fair
Market Value of shares of stock shall be determined as of the time the option
with respect to such shares is granted.

                                       11

<PAGE>

         9.   ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.

              In the event of any stock dividend, stock split, reverse stock
split, recapitalization, combination, reclassification, or similar change in
the capital structure of the Company, appropriate adjustments shall be made
in the number, Exercise Price and class of shares of stock subject to the
Option. If a majority of the shares which are of the same class as the shares
that are subject to the Option are exchanged for, converted into, or
otherwise become (whether or not pursuant to an Ownership Change Event)
shares of another corporation (the "NEW SHARES"), the Board may unilaterally
amend the Option to provide that the Option is exercisable for New Shares. In
the event of any such amendment, the Number of Option Shares and the Exercise
Price shall be adjusted in a fair and equitable manner, as determined by the
Board, in its sole discretion. Notwithstanding the foregoing, any fractional
share resulting from an adjustment pursuant to this Section 9 shall be
rounded up or down to the nearest whole number, as determined by the Board,
and in no event may the Exercise Price be decreased to an amount less than
the par value, if any, of the stock subject to the Option. The adjustments
determined by the Board pursuant to this Section 9 shall be final, binding
and conclusive.

         10.  RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT.

              The Optionee shall have no rights as a stockholder with respect
to any shares covered by the Option until the date of the issuance of a
certificate for the shares for which the Option has been exercised (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company). No adjustment shall be made for
dividends, distributions or other rights for which the record date is prior
to the date such certificate is issued, except as provided in Section 9. If
the Optionee is an Employee, the Optionee understands and acknowledges that,
except as otherwise provided in a separate, written employment agreement
between a Participating Company and the Optionee, the Optionee's employment
is "at will" and is for no specified term. Nothing in this Option Agreement
shall confer upon the Optionee, whether an Employee or Consultant, any right
to continue in the Service of a Participating Company or interfere in any way
with any right of the Participating Company Group to terminate the Optionee's
Service as an Employee or Consultant, as the case may be, at any time.

         11.  NOTICE OF SALES UPON DISQUALIFYING DISPOSITION.

              The Optionee shall dispose of the shares acquired pursuant to
the Option only in accordance with the provisions of this Option Agreement.
In addition, the Optionee shall promptly notify the Chief Financial Officer
of the Company if the Optionee disposes of any of the shares acquired
pursuant to the Option within one (1) year after the date of the Optionee
exercises all or part of the Option or within two (2) years after the Date of
Option Grant. Until such time as the Optionee disposes of such shares in a
manner consistent with the provisions of this Option Agreement, unless
otherwise expressly authorized by the Company, the Optionee shall hold all
shares acquired pursuant to the Option in the Optionee's name (and not in the
name of any nominee) for the one-year period immediately after the exercise
of the Option and the

                                       12

<PAGE>

two-year period immediately after Date of Option Grant. At any time during
the one-year or two-year periods set forth above, the Company may place a
legend on any certificate representing shares acquired pursuant to the Option
requesting the transfer agent for the Company's stock to notify the Company
of any such transfers. The obligation of the Optionee to notify the Company
of any such transfer shall continue notwithstanding that a legend has been
placed on the certificate pursuant to the preceding sentence.

         12.  LEGENDS.

              The Company may at any time place legends referencing any
applicable federal, state or foreign securities law restrictions on all
certificates representing shares of stock subject to the provisions of this
Option Agreement. The Optionee shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired
pursuant to the Option in the possession of the Optionee in order to carry
out the provisions of this Section.

         13.  MISCELLANEOUS PROVISIONS.

              13.1 BINDING EFFECT. Subject to the restrictions on transfer
set forth herein, this Option Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective heirs, executors,
administrators, successors and assigns.

              13.2 TERMINATION OR AMENDMENT. The Board may terminate or amend
the Plan or the Option at any time; provided, however, that except as
provided in Section 8.2 in connection with a Change in Control, no such
termination or amendment may adversely affect the Option or any unexercised
portion hereof without the consent of the Optionee unless such termination or
amendment is necessary to comply with any applicable law or government
regulation or is required to enable the Option to qualify as an incentive
stock option. No amendment or addition to this Option Agreement shall be
effective unless in writing.

              13.3 NOTICES. Any notice required or permitted hereunder shall
be given in writing and shall be deemed effectively given (except to the
extent that this Option Agreement provides for effectiveness only upon actual
receipt of such notice) upon personal delivery or upon deposit in the United
States Post Office, by registered or certified mail, with postage and fees
prepaid, addressed to the other party at the address of such party as set
forth in the Notice or at such other address as such party may designate in
writing from time to time to the other party.

              13.4 INTEGRATED AGREEMENT. This Option Agreement and the Notice
constitute the entire understanding and agreement of the Optionee and the
Participating Company Group with respect to the subject matter contained
herein and therein, and there are no agreements, understandings,
restrictions, representations, or warranties among the Optionee and the
Participating Company Group with respect to such subject matter other than
those as set forth or provided for herein or therein. To the extent
contemplated herein, the provisions of this Option Agreement shall survive
any exercise of the Option and shall remain in full force and effect.

162(m), the Board may establish a Committee of "outside directors" within the
meaning of Section 162(m) to approve the grant of any Option which might
reasonably be anticipated to result in the payment of employee remuneration
that would otherwise exceed the limit on employee remuneration deductible for
income tax purposes pursuant to Section 162(m).

         4. SHARES SUBJECT TO PLAN.

              4.1 MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be the sum of (a) the number of shares
that remain available for grant pursuant to the Predecessor Plan immediately
prior to the Predecessor Plan Termination Date (not to exceed 481,000
shares)(1) and (b) the number of unissued shares subject to each option
outstanding under the Predecessor Plan immediately prior to the Predecessor
Plan Termination Date which for any reason subsequently expires or is
terminated or canceled (not to exceed 67,000 shares).(2) Such shares shall
consist of authorized but unissued or reacquired shares of Stock or any
combination thereof. If an outstanding Option for any reason expires or is
terminated or canceled, or if shares of Stock acquired upon exercise of an
Option subject to a Company repurchase option and are repurchased by the
Company at the Optionee's exercise price, the shares of Stock allocable to
the unexercised portion of such Option or such repurchased shares of Stock
shall again be available for issuance under the Plan.

              4.2 ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event
of any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of
the Company, appropriate adjustments shall be made in the number and class of
shares subject to the Plan and to any outstanding Options, in the

--------
(1) On the Predecessor Plan Termination Date, the number of shares available for
grant under the Predecessor Plan was 529,501. Therefore, the applicable number
of shares under clause (a) is 481,000.

(2) Additional shares made available under this Plan under clause (b) must be
registered on Form S-8 under this Plan. (Filing fees paid for unissued shares
registered under Form S-8 for the Predecessor Plan may be transferred to Form
S-8 for this Plan.)

                                      6

Section 162(m) Grant Limit set forth in Section 5.4, and in the exercise price
per share of any outstanding Options. If a majority of the shares which are of
the same class as the shares that are subject to outstanding Options are
exchanged for, converted into, or otherwise become (whether or not pursuant to
an Ownership Change Event, as defined in Section 8.1) shares of another
corporation (the "NEW SHARES"), the Board may unilaterally amend the outstanding
Options to provide that such Options are exercisable for New Shares. In the
event of any such amendment, the number of shares subject to, and the exercise
price per share of, the outstanding Options shall be adjusted in a fair and
equitable manner as determined by the Board, in its discretion. Notwithstanding
the foregoing, any fractional share resulting from an adjustment pursuant to
this Section 4.2 shall be rounded down to the nearest whole number, and in no
event may the exercise price of any Option be decreased to an amount less than
the par value, if any, of the stock subject to the Option. The adjustments
determined by the Board pursuant to this Section 4.2 shall be final, binding and
conclusive.

         5. ELIGIBILITY AND OPTION LIMITATIONS.

              5.1 PERSONS ELIGIBLE FOR OPTIONS. Options may be granted only
to Employees, Consultants and Directors. For purposes of the foregoing
sentence, "Employees," "Consultants" and "Directors" shall include
prospective Employees, prospective Consultants, and prospective Directors to
whom Options are granted in connection with written offers of employment or
other service relationship with a Participating Company. Eligible persons may
be granted more than one (1) Option.

              5.2 OPTION GRANT RESTRICTIONS. Any person who is not an
Employee on the effective date of the grant of an Option to such person may
be granted only a Nonstatutory Stock Option. An Incentive Stock Option
granted to a prospective Employee upon the condition that such person become
an Employee shall be deemed granted effective on the date such person
commences Service with a Participating Company, with an exercise price
determined as of such date in accordance with Section 6.1.

              5.3 FAIR MARKET VALUE LIMITATION. To the extent that options
designated as Incentive Stock Options (granted under all stock option plans
of the Participating Company Group, including the Plan) become exercisable by
an Optionee for the first time during any calendar year for stock having a
Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the
portions of such options which exceed such amount shall be treated as
Nonstatutory Stock Options. For purposes of this Section 5.3, options
designated as Incentive Stock Options shall be taken into account in the
order in which they were granted, and the Fair Market Value of stock shall be
determined as of the time the option with respect to such stock is granted.
If the Code is amended to provide for a different limitation from that set
forth in this Section 5.3, such different limitation shall be deemed
incorporated herein effective as of the date and with respect to such Options
as required or permitted by such amendment to the Code. If an Option is
treated as an Incentive Stock Option in part and as a Nonstatutory Stock
Option in part by reason of the limitation set forth in this Section 5.3, the
Optionee may designate which portion of such Option the Optionee is
exercising. In the absence of such designation, the Optionee shall be deemed
to have exercised the Incentive Stock Option portion of the Option

                                      7

<PAGE>

first. Separate certificates representing each such portion shall be issued
upon the exercise of the Option.

              5.4 SECTION 162(m) GRANT LIMIT. Subject to adjustment as
provided in Section 4.2, no Employee shall be granted one or more Options
within any fiscal year of the Company which in the aggregate are for the
purchase of more than Two Hundred Fifty Thousand (250,000) shares; provided,
however, that such limit shall be Five Hundred Thousand (500,000) shares in
the case of any Employee who serves as the Chairman of the Board, President,
Chief Executive Officer or Chief Operating Officer at any time during such
fiscal year (the "SECTION 162(m) GRANT LIMIT"). An Option which is canceled
in the same fiscal year of the Company in which it was granted shall continue
to be counted against the Section 162(m) Grant Limit for such period.

         6. TERMS AND CONDITIONS OF OPTIONS.

              Options shall be evidenced by Option Agreements specifying the
number of shares of Stock covered thereby, in such form as the Board shall
from time to time establish. No Option or purported Option shall be a valid
and binding obligation of the Company unless evidenced by a fully executed
Option Agreement. Option Agreements may incorporate all or any of the terms
of the Plan by reference and shall comply with and be subject to the
following terms and conditions:

              6.1 EXERCISE PRICE. The exercise price for each Option shall be
established in the discretion of the Board; provided, however, that (a) the
exercise price per share for an Incentive Stock Option shall be not less than
the Fair Market Value of a share of Stock on the effective date of grant of
the Option, (b) the exercise price per share for a Nonstatutory Stock Option
shall be not less than eighty-five percent (85%) of the Fair Market Value of
a share of Stock on the effective date of grant of the Option, and (c) no
Incentive Stock Option granted to a Ten Percent Owner Optionee shall have an
exercise price per share less than one hundred ten percent (110%) of the Fair
Market Value of a share of Stock on the effective date of grant of the
Option. Notwithstanding the foregoing, an Option (whether an Incentive Stock
Option or a Nonstatutory Stock Option) may be granted with an exercise price
lower than the minimum exercise price set forth above if such Option is
granted pursuant to an assumption or substitution for another option in a
manner qualifying under the provisions of Section 424(a) of the Code.

              6.2 EXERCISE PERIOD. Options shall be exercisable at such time
or times, or upon such event or events, and subject to such terms,
conditions, performance criteria, and restrictions as shall be determined by
the Board and set forth in the Option Agreement evidencing such Option;
provided, however, that (a) no Option shall be exercisable after the
expiration of ten (10) years after the effective date of grant of such
Option, (b) no Incentive Stock Option granted to a Ten Percent Owner Optionee
shall be exercisable after the expiration of five (5) years after the
effective date of grant of such Option, and (c) no Option granted to a
prospective Employee, prospective Consultant or prospective Director may
become exercisable prior to the date on which such person commences Service
with a Participating Company. Subject to the foregoing, unless otherwise
specified by the Board in the grant of an Option, any

                                      8

<PAGE>

Option granted hereunder shall have a term of five (5) years from the
effective date of grant of the Option.

         6.3 PAYMENT OF EXERCISE PRICE.

                       (a) FORMS OF CONSIDERATION AUTHORIZED. Except as
otherwise provided below, payment of the exercise price for the number of
shares of Stock being purchased pursuant to any Option shall be made (i) in
cash, by check or cash equivalent, (ii) by tender to the Company, or
attestation to the ownership, of shares of Stock owned by the Optionee having
a Fair Market Value (as determined by the Company without regard to any
restrictions on transferability applicable to such stock by reason of federal
or state securities laws or agreements with an underwriter for the Company)
not less than the exercise price, (iii) by the assignment of the proceeds of
a sale or loan with respect to some or all of the shares being acquired upon
the exercise of the Option (including, without limitation, through an
exercise complying with the provisions of Regulation T as promulgated from
time to time by the Board of Governors of the Federal Reserve System) (a
"CASHLESS EXERCISE"), (iv) if the Optionee is an Employee and in the
Company's sole discretion at the time the Option is exercised, by the
Optionee's promissory note in a form approved by the Company, (v) by such
other consideration as may be approved by the Board from time to time to the
extent permitted by applicable law, or (vi) by any combination thereof. The
Board may at any time or from time to time, by adoption of or by amendment to
the standard forms of Option Agreement described in Section 7, or by other
means, grant Options which do not permit all of the foregoing forms of
consideration to be used in payment of the exercise price or which otherwise
restrict one or more forms of consideration.

                       (b) LIMITATIONS ON FORMS OF CONSIDERATION.

                                (i) TENDER OF STOCK.  Notwithstanding the
foregoing, an Option may not be exercised by tender to the Company, or
attestation to the ownership, of shares of Stock to the extent such tender or
attestation would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock.
Unless otherwise provided by the Board, an Option may not be exercised by
tender to the Company, or attestation to the ownership, of shares of Stock
unless such shares either have been owned by the Optionee for more than six
(6) months or were not acquired, directly or indirectly, from the Company.

                                (ii) CASHLESS EXERCISE.  The Company
reserves, at any and all times, the right, in the Company's sole and absolute
discretion, to establish, decline to approve or terminate any program or
procedures for the exercise of Options by means of a Cashless Exercise.

                                (iii) PAYMENT BY PROMISSORY NOTE.  No
promissory note shall be permitted if the exercise of an Option using a
promissory note would be a violation of any law. Any permitted promissory
note shall be on such terms as the Board shall determine at the time the
Option is granted. The Board shall have the authority to permit or require
the Optionee to

                                      9

<PAGE>

secure any promissory note used to exercise an Option with the shares of
Stock acquired upon the exercise of the Option or with other collateral
acceptable to the Company. Unless otherwise provided by the Board, if the
Company at any time is subject to the regulations promulgated by the Board of
Governors of the Federal Reserve System or any other governmental entity
affecting the extension of credit in connection with the Company's
securities, any promissory note shall comply with such applicable
regulations, and the Optionee shall pay the unpaid principal and accrued
interest, if any, to the extent necessary to comply with such applicable
regulations.

              6.4 TAX WITHHOLDING. The Company shall have the right, but not
the obligation, to deduct from the shares of Stock issuable upon the exercise
of an Option, or to accept from the Optionee the tender of, a number of whole
shares of Stock having a Fair Market Value, as determined by the Company,
equal to all or any part of the federal, state, local and foreign taxes, if
any, required by law to be withheld by the Participating Company Group with
respect to such Option or the shares acquired upon the exercise thereof.
Alternatively or in addition, in its sole discretion, the Company shall have
the right to require the Optionee, through payroll withholding, cash payment
or otherwise, including by means of a Cashless Exercise, to make adequate
provision for any such tax withholding obligations of the Participating
Company Group arising in connection with the Option or the shares acquired
upon the exercise thereof. The Company shall have no obligation to deliver
shares of Stock until the Participating Company Group's tax withholding
obligations have been satisfied by the Optionee.

              6.5 EFFECT OF TERMINATION OF SERVICE.

                       (a) OPTION EXERCISABILITY. Subject to earlier
termination of the Option as otherwise provided herein and unless otherwise
provided by the Board in the grant of an Option and set forth in the Option
Agreement, an Option shall be exercisable after an Optionee's termination of
Service as follows:

                                (i) DISABILITY.  If the Optionee's Service
with the Participating Company Group is terminated because of the Disability
of the Optionee, the Option, to the extent unexercised and exercisable on the
date on which the Optionee's Service terminated, may be exercised by the
Optionee (or the Optionee's guardian or legal representative) at any time
prior to the expiration of three (3) months (or such longer period of time as
determined by the Board, in its discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the date of
expiration of the Option's term as set forth in the Option Agreement
evidencing such Option (the "OPTION EXPIRATION DATE").

                                (ii) DEATH. If the Optionee's Service with
the Participating Company Group is terminated because of the death of the
Optionee, the Option, to the extent unexercised and exercisable on the date
on which the Optionee's Service terminated, may be exercised by the
Optionee's legal representative or other person who acquired the right to
exercise the Option by reason of the Optionee's death at any time prior to
the expiration of six (6) months (or such longer period of time as determined
by the Board, in its discretion) after the date on which the Optionee's
Service terminated, but in any event no later than the Option

                                      10

<PAGE>

Expiration Date. The Optionee's Service shall be deemed to have terminated on
account of death if the Optionee dies within three (3) months after the
Optionee's termination of Service.

                                (iii) TERMINATION AFTER CHANGE IN CONTROL.
The Board may, in its discretion, provide in any Option Agreement that if the
Optionee's Service with the Participating Company Group ceases as a result of
"Termination After a Change in Control" (as defined in such Option
Agreement), then (1) the Option, to the extent unexercised and exercisable on
the date on which the Optionee's Service terminated, may be exercised by the
Optionee (or the Optionee's guardian or legal representative) at any time
prior to the expiration of six months (or such longer period of time as
determined by the Board, in its discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date, and (2) the exercisability and vesting of the Option shall
be accelerated effective as of the date on which the Optionee's Service
terminated to such extent, if any, as shall have been determined by the
Board, in its discretion, and set forth in the Option Agreement.
Notwithstanding the foregoing, if it is determined that the provisions or
operation of this Section 6.5(a)(iii) would preclude treatment of a Change in
Control as a "pooling-of-interests" for accounting purposes and provided
further that in the absence of the preceding sentence such Change in Control
would be treated as a "pooling-of-interests" for accounting purposes, then
this Section 6.5(a)(iii) shall be void AB INITIO, and the vesting and
exercisability of the Option shall be determined under any other applicable
provision of the Plan or the Option Agreement evidencing such Option.

                                (iv) OTHER TERMINATION OF SERVICE.  If the
Optionee's Service with the Participating Company Group terminates for any
reason, except Disability, death or Termination After a Change in Control,
the Option, to the extent unexercised and exercisable by the Optionee on the
date on which the Optionee's Service terminated, may be exercised by the
Optionee within thirty days (30) days (or such longer period of time as
determined by the Board, in its discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

                       (b) EXTENSION IF EXERCISE PREVENTED BY LAW.
Notwithstanding the foregoing, if the exercise of an Option within the
applicable time periods set forth in Section 6.5(a) is prevented by the
provisions of Section 11 below, the Option shall remain exercisable until
thirty (30) days (or such longer period of time as is determined by the
Board, in its discretion) after the date the Optionee is notified by the
Company that the Option is exercisable, but in any event no later than the
Option Expiration Date.

                       (c) EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(B).
Notwithstanding the foregoing, if a sale within the applicable time periods
set forth in Section 6.5(a) of shares acquired upon the exercise of the
Option would subject the Optionee to suit under Section 16(b) of the Exchange
Act, the Option shall remain exercisable until the earliest to occur of (i)
the tenth (10th) day following the date on which a sale of such shares by the
Optionee would no longer be subject to such suit, (ii) the one hundred and
ninetieth (190th) day after the Optionee's termination of Service, or (iii)
the Option Expiration Date.

                                      11

<PAGE>

         7. STANDARD FORM OF OPTION AGREEMENT.

              7.1 INCENTIVE STOCK OPTIONS. Unless otherwise provided by the
Board at the time the Option is granted, an Option designated as an
"Incentive Stock Option" shall comply with and be subject to the terms and
conditions set forth in the form of Incentive Stock Option Agreement adopted
by the Board concurrently with its adoption of the Plan and as amended from
time to time.

              7.2 NONSTATUTORY STOCK OPTION AGREEMENT. Unless otherwise
provided by the Board at the time the Option is granted, an Option designated
as a "Nonstatutory Stock Option" shall comply with and be subject to the
terms and conditions set forth in the form of Nonstatutory Stock Option
Agreement adopted by the Board concurrently with its adoption of the Plan and
as amended from time to time.

              7.3 AUTHORITY TO VARY TERMS. The Board shall have the authority
from time to time to vary the terms of any of the standard forms of Option
Agreement described in this Section 7 either in connection with the grant or
amendment of an individual Option or in connection with the authorization of
a new standard form or forms; provided, however, that the terms and
conditions of any such new, revised or amended standard form or forms of
Option Agreement are not inconsistent with the terms of the Plan.

         8. CHANGE IN CONTROL.

              8.1 DEFINITIONS. Except as otherwise determined by the Board
and set forth in an Option Agreement, the following terms shall have their
respective meanings set forth below:

                       (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to
have occurred if any of the following occurs with respect to the Company: (i)
the direct or indirect sale or exchange in a single or series of related
transactions by the stockholders of the Company of more than fifty percent
(50%) of the voting stock of the Company; (ii) a merger or consolidation in
which the Company is a party; (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or (iv) a liquidation or
dissolution of the Company.

                       (b) A "CHANGE IN CONTROL" shall mean an Ownership
Change Event or a series of related Ownership Change Events (collectively,
the "TRANSACTION") wherein the stockholders of the Company immediately before
the Transaction do not retain immediately after the Transaction, in
substantially the same proportions as their ownership of shares of the
Company's voting stock immediately before the Transaction, direct or indirect
beneficial ownership of more than fifty percent (50%) of the total combined
voting power of the outstanding voting stock of the Company or the
corporation or corporations to which the assets of the Company were
transferred (the "TRANSFEREE CORPORATION(S)"), as the case may be. For
purposes of the preceding sentence, indirect beneficial ownership shall
include, without limitation, an interest resulting from ownership of the
voting stock of one or more corporations which, as a result of the
Transaction, own the Company or the Transferee Corporation(s), as the

                                      12

<PAGE>

case may be, either directly or through one or more subsidiary corporations.
The Board shall have the right to determine whether multiple sales or
exchanges of the voting stock of the Company or multiple Ownership Change
Events are related, and its determination shall be final, binding and
conclusive.

              8.2 EFFECT OF CHANGE IN CONTROL ON OPTIONS. In the event of a
Change in Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), shall either assume the Company's rights and obligations under
outstanding Options or substitute for outstanding Options substantially
equivalent options for the Acquiring Corporation's stock. The Board may, in
its discretion, provide in any Option Agreement that, in the event of a
Change in Control, the exercisability and vesting of the outstanding Option
shall accelerate upon such circumstances and to such extent as specified in
such Option Agreement. The exercise or vesting of any Option that was
permissible solely by reason of this Section 8.2 and the provisions of such
Option Agreement shall be conditioned upon the consummation of the Change in
Control. Any Options which are neither assumed or substituted for by the
Acquiring Corporation in connection with the Change in Control nor exercised
as of the date of the Change in Control shall terminate and cease to be
outstanding effective as of the date of the Change in Control.
Notwithstanding the foregoing, if the corporation the stock of which is
subject to the outstanding Options immediately prior to an Ownership Change
Event described in Section 8.1(a)(i) constituting a Change in Control is the
surviving or continuing corporation and immediately after such Ownership
Change Event less than fifty percent (50%) of the total combined voting power
of its voting stock is held by another corporation or by other corporations
that are members of an affiliated group within the meaning of Section 1504(a)
of the Code without regard to the provisions of Section 1504(b) of the Code,
the outstanding Options shall not terminate unless the Board otherwise
provides in its sole discretion.

         9. PROVISION OF INFORMATION.

              Each Optionee shall be given access to information concerning
the Company equivalent to that information generally made available to the
Company's common stockholders.

         10. NONTRANSFERABILITY OF OPTIONS.

              During the lifetime of the Optionee, an Option shall be
exercisable only by the Optionee or the Optionee's guardian or legal
representative. No Option shall be assignable or transferable by the
Optionee, except by will or by the laws of descent and distribution.

         11. COMPLIANCE WITH SECURITIES LAW.

              The grant of Options and the issuance of shares of Stock upon
exercise of Options shall be subject to compliance with all applicable
requirements of federal, state or foreign law with respect to such
securities. Options may not be exercised if the issuance of shares of Stock
upon exercise would constitute a violation of any applicable federal, state
or foreign securities laws or other law or regulations or the requirements of
any stock exchange or market system

                                      13

<PAGE>

upon which the Stock may then be listed. In addition, no Option may be
exercised unless (a) a registration statement under the Securities Act shall
at the time of exercise of the Option be in effect with respect to the shares
issuable upon exercise of the Option or (b) in the opinion of legal counsel
to the Company, the shares issuable upon exercise of the Option may be issued
in accordance with the terms of an applicable exemption from the registration
requirements of the Securities Act. The inability of the Company to obtain
from any regulatory body having jurisdiction the authority, if any, deemed by
the Company's legal 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 any
Option, the Company may require the Optionee to satisfy any qualifications
that may be necessary or appropriate, to evidence compliance with any
applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

         12. INDEMNIFICATION.

              In addition to such other rights of indemnification as they may
have as members of the Board or officers or employees of the Participating
Company Group, members of the Board and any officers or employees of the
Participating Company Group to whom authority to act for the Board or the
Company is delegated shall be indemnified by the Company against all
reasonable expenses, including attorneys' fees, actually and necessarily
incurred in connection with the defense of any action, suit or proceeding, or
in connection with any appeal therein, to which they or any of them may be a
party by reason of any action taken or failure to act under or in connection
with the Plan, or any right granted hereunder, and against all amounts paid
by them in settlement thereof (provided such settlement is approved by
independent legal counsel selected by the Company) or paid by them in
satisfaction of a judgment in any such action, suit or proceeding, except in
relation to matters as to which it shall be adjudged in such action, suit or
proceeding that such person is liable for gross negligence, bad faith or
intentional misconduct in duties; provided, however, that within sixty (60)
days after the institution of such action, suit or proceeding, such person
shall offer to the Company, in writing, the opportunity at its own expense to
handle and defend the same.

         13. TERMINATION OR AMENDMENT OF PLAN.

              The Board may terminate or amend the Plan at any time. However,
subject to changes in applicable law, regulations or rules that would permit
otherwise, without the approval of the Company's stockholders, there shall be
(a) no increase in the maximum aggregate number of shares of Stock that may
be issued under the Plan (except by operation of the provisions of Section
4.2), (b) no change in the class of persons eligible to receive Incentive
Stock Options, and (c) no other amendment of the Plan that would require
approval of the Company's stockholders under any applicable law, regulation
or rule. No termination or amendment of the Plan shall affect any then
outstanding Option unless expressly provided by the Board. In any event, no
termination or amendment of the Plan may adversely affect any then
outstanding Option without the consent of the Optionee, unless such
termination or amendment is required to

                                      14

<PAGE>

enable an Option designated as an Incentive Stock Option to qualify as an
Incentive Stock Option or is necessary to comply with any applicable law,
regulation or rule.

         IN WITNESS WHEREOF, the undersigned Secretary of the Company
certifies that the foregoing Network Computing Devices, Inc. 1999 Stock
Option Plan was duly adopted by the Board on March 31, 1999.
