Participating Company for which the Optionee renders such Service, provided that
there is no interruption or termination of the Optionee's Service. Furthermore,
an Optionee's Service with the Participating Company Group shall not be deemed
to have terminated if the Optionee takes any military leave, sick leave, or

that if any such leave exceeds ninety (90) days, on the ninety-first (91st) day

<PAGE>


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 vesting under the Optionee's Option Agreement. 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

when the employee-employer relationship between an Optionee and the
Participating Company is terminated for any reason, with or without cause,
including, but not by way of limitation, a termination by resignation,
discharge, death, Disability or retirement; but excluding (i) terminations where
there is a simultaneous reemployment or continuing employment of an Optionee by
any Participating Company, (ii) at the discretion of the Board, terminations
which result in a temporary severance of the employee-employer relationship, and
(iii) at the discretion of the Board, terminations which are followed by the
simultaneous establishment of a consulting relationship by a Participating
Company with the former employee. The Board, in its absolute discretion, shall
determine the effect of all matters and questions relating to Termination of
Employment, including, but not by way of limitation, the question of whether a
Termination of Employment resulted from a discharge for good cause, and all
questions of whether particular leaves of absence constitute Terminations of
Employment; provided, however, that, unless otherwise determined by the Board in
its discretion, a leave of absence, change in status from an employee to an
independent contractor or other change in the employee-employer relationship
shall constitute a Termination of Employment if, and to the extent that, such
leave of absence, change in status or other change interrupts employment for the
purposes of Section 422(a)(2) of the Code and the then applicable regulations
and revenue rulings under said Section. Notwithstanding any other provision of
this Plan, each Participating Company has an absolute and unrestricted right to
terminate an Employee's employment at any time for any reason whatsoever, with
or without cause, except to the extent expressly provided otherwise in writing.

                           (aa) "Termination without Cause" shall mean the time
when the employee-employer relationship between an Optionee and the Company or
any other Participating Company is terminated without cause, as termination
without cause is defined in the Optionee's employment agreement; provided
however, that if termination without cause is not therein defined, it shall have
such meaning, in conformance with applicable law, as the Board shall determine
is appropriate.

convenience only and shall not affect the meaning or interpretation of any

         3.       ADMINISTRATION.

                  3.1 ADMINISTRATION BY THE BOARD. The Plan shall be

restrictions applicable to each Option (which need not be identical) and any
shares acquired upon the exercise thereof, including, without limitation, (i)
the exercise price of the Option, (ii) the method of payment for shares
purchased upon the exercise of the Option, (iii) the method for satisfaction of
any tax withholding obligation arising in connection with the Option or such

                                       5
<PAGE>


                           (e) to amend, modify, extend, cancel or renew any
Option or to waive any restrictions or conditions applicable to any Option or
any shares acquired upon the exercise thereof;

                           (f) to accelerate, continue, extend or defer the
exercisability of any Option or the vesting of any shares acquired upon the
exercise thereof, including with respect to the period following an Optionee's

other determinations and take such other actions with respect to the Plan or any
Option as the Board may deem advisable to the extent consistent with the Plan
and applicable law.

         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 One Million Four Hundred Thousand
(1,400,000) and 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 are acquired upon the
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 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


                                       6
<PAGE>


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.

                  Notwithstanding anything herein to the contrary, only the
following classes of persons shall be eligible to receive grants of Options
under this Plan: (i) except as provided in (ii) below, key Employees and
Consultants who are not Officers or Directors of the Company, and (ii) newly
hired Employees (including Employees who will become Officers or Directors of
the Company) who have not previously been employed by the Company and with
respect to whom Options are to be granted as an inducement essential to such
Employees' entering into employment contracts with the Company. Notwithstanding
the foregoing, a Consultant shall not be eligible for the grant of an Option if,
at the time of grant, a Form S-8 Registration Statement under the Securities Act
("Form S-8") is not available to register either the offer or the sale of the
Company's securities to such Consultant because of the nature of the services
that the Consultant is providing to the Company, or because the Consultant is
not a natural person, or as otherwise provided by the rules governing the use of
Form S-8, unless the Company determines both (i) that such grant (A) shall be
registered in another manner under the Securities Act (E.G., on a Form S-3
Registration Statement) or (B) does not require registration under the
Securities Act in order to comply with the requirements of the Securities Act,
if applicable, and (ii) that such grant complies with the securities laws of all
other relevant jurisdictions.

         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. Notwithstanding the foregoing, an
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 and (b) 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 Option granted hereunder shall have a
term of ten (10) 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) 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
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.


                                       8
<PAGE>


                  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 the minimum amount required to be withheld based on the statutory withholding
rates for federal and state tax purposes that apply to supplemental taxable
income. The Fair Market Value of the shares of Stock to be withheld shall be
determined on the date that the amount of tax to be withheld is to be
determined. Alternatively or in addition, in its 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 or to release shares of Stock from an escrow established pursuant to the
Option Agreement 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, 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 twelve (12) 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
twelve (12) 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. The Optionee's Service
shall be deemed to have terminated on account of death if the Optionee dies
within thirty (30) days (or such longer period of time as determined by the
Board, in its discretion) after the Optionee's termination of Service.

                                    (iii) Other Termination of Service. If the
Optionee's Service with the Participating Company Group terminates for any
reason, except Disability or death, 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 three (3) months (or such


                                       9
<PAGE>


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 6.6(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 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.

         7.       STANDARD FORMS OF OPTION AGREEMENT.

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

                  7.2 AUTHORITY TO VARY TERMS. The Board shall have the
authority from time to time to vary the terms of any of the standard form 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.

                           (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, a
"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


                                       10
<PAGE>


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 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"), may 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. For purposes of this
Section 8.2, an Option shall be deemed assumed if, following the Change in
Control, the Option confers the right to purchase in accordance with its terms
and conditions, for each share of Stock subject to the Option immediately prior
to the Change in Control, the consideration (whether stock, cash or other
securities or property) to which a holder of a share of Stock on the effective
date of the Change in Control was entitled. 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, shares acquired upon exercise of an
Option prior to the Change in Control and any consideration received pursuant to
the Change in Control with respect to such shares shall continue to be subject
to all applicable provisions of the Option Agreement evidencing such Option
except as otherwise provided in such Option Agreement.

                  8.3 ACCELERATION OF VESTING UPON CERTAIN EVENTS FOLLOWING
CHANGE OF CONTROL. In the event of a Change in Control wherein the Acquiring
Corporation does assume such Options or substitutes for outstanding Options
substantially equivalent options for the Acquiring Corporation's stock, then,
with respect to each Option held by persons then performing services as
Employees, the vesting of each Option (and, if applicable, the time during which
such Option may be exercised) shall be accelerated and such Option shall become
vested and exercisable with respect to fifty percent (50%) of the unvested
portion of such Option, if, within one (1) year from the date of such Change in
Control, either of the following events occurs: (1) a Termination without Cause
of an Optionee by the Participating Company or the Acquiring Corporation or (2)
the Employee holding such Option effects a Termination of Employment due to the
fact that there is a material reduction in such Employee's salary (excluding
bonuses (whether or not payable in cash), employee benefits or other non-cash
compensation) without the Employee's express consent.

         9.       PROVISION OF INFORMATION.

                  To the extent required by applicable securities laws and
regulations, each Optionee shall receive financial statements of the Company at
least annually.


                                       11
<PAGE>


         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 and 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 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.


                                       12

         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 no 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 may adversely affect any then outstanding Option or any
unexercised portion thereof, without the consent of the Optionee, unless such
termination or amendment is required to comply with any applicable law,
regulation or rule.

                                 JNI CORPORATION

                         TERMS OF STOCK OPTION AGREEMENT


                  The Company has granted to the Optionee, pursuant to a Stock
Option Grant Agreement (the "Grant Agreement") and the JNI Corporation 2000
Non-Qualified Stock Option Plan (the "Plan"), an Option to purchase certain
shares of Stock, upon the terms and conditions set forth in this Agreement (the
"Option Agreement"). The Option shall in all respects be subject to the terms
and conditions of the Grant Agreement and the Plan, the provisions of which are
incorporated herein by reference.


         1.       DEFINITIONS AND CONSTRUCTION.

                  1.1 DEFINITIONS. Unless otherwise defined herein, capitalized
terms shall have the meanings assigned to such terms in the Grant Agreement or
the Plan.

                  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 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 CONSEQUENCES.

                  As indicated in the Grant Agreement, this Option is intended
to be a Nonstatutory Stock Option, which is not intended to qualify as an
Incentive Stock Option. The Optionee should consult with the Optionee's own tax
advisor regarding the tax effects of this Option.

         3.       EXERCISE OF THE OPTION.

                  3.1 RIGHT TO EXERCISE. Except as otherwise provided herein,
the Option shall be exercisable on and after the first anniversary of the Date
of Option Grant and prior to the termination of the Option (as provided in
Section 5) in an amount not to exceed the Number of Option Shares multiplied by
the Vested Ratio less the number of shares previously acquired upon exercise of
the Option.

                  3.2 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 Agreement. The written notice must be signed by the Optionee
and must be delivered in person, by certified or registered mail, return receipt
requested, by confirmed facsimile transmission, or by such other means as the
Company may permit, to the Chief Financial Officer of the Company, or other
authorized representative of the Company, prior to the termination of the Option
as set forth in Section 5, accompanied by full payment of the aggregate


<PAGE>


Exercise Price for the number of shares of Stock being purchased. The Option
shall be deemed to be exercised upon receipt by the Company of such written
notice and the aggregate Exercise Price.

                  3.3 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, by check, or cash equivalent, (ii) by tender to the Company, or
attestation to the ownership, 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 3.3(b), or (iv) by any combination of the foregoing.

                           (b) LIMITATIONS ON FORMS OF CONSIDERATION.

                                    (i) Tender of Stock. Notwithstanding the
foregoing, the 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 to the ownership, 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, 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. 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. Generally, and
without limiting the Company's absolute discretion, a "cashless exercise" will
only be permitted at such times in which the shares underlying this Option are
publicly traded.

                  3.4 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 Company, 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


                                       2
<PAGE>


cautioned that the Option is not exercisable unless the tax withholding
obligations of the Company 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.

                  3.5 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, the Optionee's heirs.

                  3.6 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 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. 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.

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

         4.       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 6, 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.


                                       3
<PAGE>


         5.       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 6, or (c) pursuant to a Change in Control, to the extent
provided in the Plan.

         6.       EFFECT OF TERMINATION OF SERVICE.

                  6.1 OPTION EXERCISABILITY.

                           (a) Disability. If the Optionee's Service with the
Company 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 twelve (12)
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 Company
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 twelve (12) 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 thirty (30) days
after the Optionee's termination of Service.

                           (c) Other Termination of Service. If the Optionee's
Service with the Company terminates for any reason, except Disability, or death,
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 three (3) months (or such other longer period of time as
determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

                  6.2 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods
set forth in Section 6.1 is prevented by the provisions of Section 3.6, 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. The Company makes no
representation as to the tax consequences of any such delayed exercise. The
Optionee should consult with the Optionee's own tax advisor as to the tax
consequences of any such delayed exercise.

                  6.3 EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods set
forth in Section 6.1 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 (10th)


                                       4
<PAGE>


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. The Company makes no representation as to the tax consequences of any such
delayed exercise. The Optionee should consult with the Optionee's own tax
advisor as to the tax consequences of any such delayed exercise.

         7.       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 4.2 of the Plan. If
the Optionee is an Employee, the Optionee understands and acknowledges that,
except as otherwise provided in a separate, written employment agreement between
the Company and the Optionee, the Optionee's employment is "at will" and is for
no specified term. Nothing in this Agreement shall confer upon the Optionee any
right to continue in the Service of the Company or interfere in any way with any
right of the Company to terminate the Optionee's Service as an Employee or
Consultant, as the case may be, at any time.

         8.       PUBLIC OFFERING.

                  The Optionee hereby agrees that in the event of any
underwritten public offering of stock made by the Company pursuant to an
effective registration statement filed under the Securities Act, the Optionee
shall not offer, sell, contract to sell, pledge, hypothecate, grant any option
to purchase or make any short sale of, or otherwise dispose of any shares of
stock of the Company or any rights to acquire stock of the Company for such
period of time from and after the effective date of such registration statement
as may be established by the underwriter for such public offering; provided,
however, that such period of time shall not exceed one hundred eighty (180) days
from the effective date of the registration statement to be filed in connection
with such public offering. The foregoing limitation shall not apply to shares
registered in the public offering under the Securities Act. The Optionee shall
be subject to this Section provided and only if the officers and directors of
the Company are also subject to similar arrangements.

         9.       RESTRICTIONS ON TRANSFER OF SHARES.

                  No shares acquired upon exercise of the Option may be sold,
exchanged, transferred (including, without limitation, any transfer to a nominee
or agent of the Optionee), assigned, pledged, hypothecated or otherwise disposed
of, including by operation of law, in any manner which violates any of the
provisions of this Agreement, and any such attempted disposition shall be void.
The Company shall not be required (a) to transfer on its books any shares which
will have been transferred in violation of any of the provisions set forth in
this Agreement or (b) to treat as owner of such shares or to accord the right to
vote as such owner or to pay dividends to any transferee to whom such shares
will have been so transferred.

         10.      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
