of any shares acquired upon the exercise thereof, including with respect to the
period following an Optionee's termination of employment or service with the

                  (h)   to prescribe, amend or rescind rules, guidelines and
policies relating to the Plan, or to adopt supplements to, or alternative

                                       4
<PAGE>   5
                  (i)   to correct any defect, supply any omission or reconcile
any inconsistency in the Plan or any Option Agreement and to make all other
determinations and take such other actions with respect to the Plan or any

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 hundred twenty-five thousand (125,000)
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 acquired, subject to repurchase,
upon the exercise of an Option are repurchased by the Company, 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.
Notwithstanding the foregoing, at any such time as the offer and sale of
securities pursuant to the Plan is subject to compliance with Section 260.140.45
of Title 10 of the California Code of Regulations ("SECTION 260.140.45"), the
total number of shares of Stock issuable upon the exercise of all outstanding
Options (together with options outstanding under any other stock option plan of
the Company) and the total number of shares provided for under any stock bonus
or similar plan of the Company shall not exceed thirty percent (30%) (or such
other higher percentage limitation as may be approved by the shareholders of the
Company pursuant to Section 260.140.45) of the then outstanding shares of the
Company as calculated in accordance with the conditions and exclusions of
Section 260.140.45.

            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 sole discretion. Notwithstanding the
foregoing, any fractional share resulting from an adjustment pursuant to this
Section 4.2 shall be rounded up or down to the nearest whole number, as
determined by the Board, 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
<PAGE>   6
            5.1.  PERSONS ELIGIBLE FOR OPTIONS. Options may be granted only to
key Employees of the Company who are actively engaged in the management and
operation of the Company's restaurants. For Purposes of the foregoing sentence,
"Employees" shall include prospective Employees to whom Options are granted in
connection with written offers of employment or other service relationship with
the Participating Company Group. 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 an
aggregate Fair Market Value greater than One Hundred Thousand Dollars
($100,000), the portion of such options which exceeds 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 first. Separate certificates representing each such
portion shall be issued upon the exercise of the Option.

      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. 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 sole 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 Option granted
to a Ten Percent Owner Optionee shall have an exercise price per share less than
one hundred ten percent (110%) 


                                       6
<PAGE>   7
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, and (d) with the
exception of an Option granted to an officer, Director or Consultant, no Option
shall become exercisable at a rate less than twenty percent (20%) per year over
a period of five (5) years from the effective date of grant of such Option,
subject to the Optionee's continued Service. 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 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)   TENDER OF STOCK. Notwithstanding the foregoing, an
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


                                       7
<PAGE>   8
redemption of the Company's stock. Unless otherwise provided by the Board, an
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.

                  (c)   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.

                  (d)   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.

            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 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.  REPURCHASE RIGHTS. Shares issued under the Plan may be subject
to a right of first refusal, one or more repurchase options, or other conditions
and restrictions as determined by the Board, in its sole discretion, at the time
the Option is granted. The Company shall have the right to assign at any time
any repurchase right it may have, whether or not such right is then exercisable,
to one or more persons as may be selected by the Company. Upon request by the
Company, each Optionee shall execute any agreement evidencing such transfer
restrictions prior to the receipt of shares of Stock hereunder and shall
promptly present to the 


                                       8
<PAGE>   9
Company any and all certificates representing shares of Stock acquired hereunder
for the placement on such certificates of appropriate legends evidencing any
such transfer restrictions.

      7.    STANDARD FORMS 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 Immediately Exercisable 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 OPTIONS. 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 Immediately Exercisable Nonstatutory Stock Option Agreement
adopted by the Board concurrently with its adoption of the Plan and as amended
from time to time.

            7.3.  STANDARD TERM OF OPTIONS. Except as otherwise provided in
Section 6.2 or 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.

            7.4.  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. Such authority shall include, but
not by way of limitation, the authority to grant Options which are not
immediately exercisable.

      8.    TRANSFER OF CONTROL.

            8.1.  DEFINITIONS.

                  (a)   An "OWNERSHIP CHANGE EVENT" shall be deemed to have

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, provided, however, that neither an initial
public offering by the Company, nor an equity or convertible securities
financing by the Company shall be deemed an Ownership Change Event or Transfer
of Control for the purpose of any accelerated vesting provision of this Option
Agreement. 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 TRANSFER OF CONTROL ON OPTIONS. In the event of an
eligible Transfer of Control, each of the outstanding Options shall receive an
additional two (2) years of accelerated vesting as of the date ten (10) days
prior to the date of the Transfer of Control. The exercise or vesting of any
Option that was permissible solely by reason of this Section 8.2 shall be
conditioned upon the consummation of the Transfer of Control. In addition, 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 Transfer of 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 Transfer of 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 Transfer of Control was
entitled. Any Options which are neither assumed or substituted for by the
Acquiring Corporation in connection with the Transfer of Control nor exercised
as of the date of the Transfer of Control shall terminate and cease to be
outstanding effective as of the date of the Transfer of Control. Notwithstanding
the foregoing, shares acquired upon exercise of an Option prior to the Transfer
of Control and any consideration received pursuant to the Transfer of 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. Furthermore, 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 Transfer of 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 


                                       10
<PAGE>   11
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.

            8.3.  NOTICE. The Company shall send to all holders of outstanding
Options at least ten (10) days' written notice prior to the consummation of a
Transfer of Control. The Company's notice shall summarize the principal terms of
the Transfer of Control including, without limitation, whether the Acquiring
Corporation is assuming the outstanding Options or substituting equivalent
options therefor.

      9.    PROVISION OF INFORMATION. At least annually, copies of the Company's
balance sheet and income statement for the just completed fiscal year shall be
made available to each Optionee and purchaser of shares of Stock upon the
exercise of an Option. The Company shall not be required to provide such
information to persons whose duties in connection with the Company assure them
access to equivalent information.

      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.   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.   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. In any event, 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 


                                       11
<PAGE>   12
termination or amendment is required to 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.

      13.   STOCKHOLDER APPROVAL. The Plan or any increase in the maximum number
of shares of Stock issuable thereunder as provided in Section 4.1 (the "MAXIMUM
SHARES") shall be approved by the stockholders of the Company within twelve (12)
months of the date of adoption thereof by the Board. Options granted prior to
stockholder approval of the Plan or in excess of the Maximum Shares previously
approved by the stockholders shall become exercisable no earlier than the date
of stockholder approval of the Plan or such increase in the Maximum Shares, as
the case may be.

that the foregoing P.F. CHANG'S CHINA BISTRO, INC. 1997 Restaurant Management
Stock Option Plan was duly adopted by the Board on July 18, 1997.

      2.    TAX CONSEQUENCES.

            1.    TAX STATUS OF OPTION. This Option is intended to be a
Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option
within the meaning of Section 422(b) of the Code.

            2.    ELECTION UNDER SECTION 83(b) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk of forfeiture, the Optionee understands that
the Optionee should consult with the Optionee's tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under
Section 83(b) of the Code, which must be filed no later than thirty (30) days
after the date on which the Optionee exercises the Option. Shares acquired upon
exercise of the Option are nontransferable and subject to a substantial risk of
forfeiture if, for example, (a) they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee's original purchase price
if the Optionee's Service terminates, (b) the Optionee is an Insider and
exercises the Option within six (6) months of the Date of the Option Grant (if a
class of equity security of the Company is registered under Section 12 of the
Exchange Act), or (c) the Optionee is subject to a restriction on transfer to
comply with "Pooling-of-Interests Accounting" rules. Failure to file an election
under Section 83(b), if appropriate, may result in adverse tax consequences to
the Optionee. The Optionee acknowledges that the Optionee has been advised to
consult with a tax advisor prior to the exercise of the Option regarding the tax
consequences to the Optionee of the exercise of the Option. AN ELECTION UNDER
SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH THE OPTIONEE
PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE OPTIONEE ACKNOWLEDGES
THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE OPTIONEE'S SOLE
RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE
TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

      3.    ADMINISTRATION. All questions of interpretation concerning this
Option Agreement shall be determined by the Board, including any duly appointed
Committee of 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.

            1.    RIGHT TO EXERCISE. Except as otherwise provided herein, the
Option shall be exercisable on and after the Initial Exercise Date and prior to
the termination of the Option (as provided in Section 6) in an amount not to
exceed the Number of Option Shares less the number of shares of Stock previously
acquired upon exercise of the Option subject to the Optionee's agreement that
any shares purchased upon exercise are subject to the Company's repurchase
rights set forth in Section 11 and to the Company's first refusal rights set
forth in Section 12. In no event shall the Option be exercisable for more shares
than the Number of Option Shares.
<PAGE>   18
            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 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 6, accompanied by (i) full payment of the aggregate Exercise
Price for the number of shares of Stock being purchased and (ii) an executed
copy, if required herein, of the then current forms of escrow and security
agreement referenced below. The Option shall be deemed to be exercised upon
receipt by the Company of such written notice, the aggregate Exercise Price,
and, if required by the Company, such executed agreements.

            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 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.(c), (iv) in the
Company's sole discretion at the time the Option is exercised, by cash for a
portion of the aggregate Exercise Price not less than the par value of the
shares being acquired, and the Optionee's promissory note for the balance of the
aggregate Exercise Price, or (v) by any combination of the foregoing.

                  (b)   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 shares 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 the 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.

                  (c)   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 establish,
modify, decline to approve or terminate any such Cashless Exercise program or
procedures.

                  (d)   PAYMENT BY PROMISSORY NOTE. No promissory note shall be
permitted if an exercise of the Option using a promissory note would be a
violation of any law. The promissory note permitted in clause (iv) of Section
4.3.(a) shall be a full recourse note in a form satisfactory to the Company,
with principal payable no more than four (4) years after the date the Option is
exercised. Interest on the principal balance of the promissory note shall be
payable in annual installments at the minimum interest rate necessary to avoid
imputed interest pursuant to all applicable sections of the Code. Such recourse
promissory note shall be secured by the shares of Stock acquired pursuant to the
then 
<PAGE>   19
current form of security agreement as approved by the Company. At any time
the Company 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. Except as the Company in its sole
discretion shall determine, the Optionee shall pay the unpaid principal balance
of the promissory note and any accrued interest thereon upon termination of the
Optionee's Service with the Participating Company Group for any reason, with or
without cause.

            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 such tax withholding obligations 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 or release such shares from any escrow provided for
herein.

            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.

            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 shares of 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. 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.
<PAGE>   20
            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 Transfer of Control to the extent
provided in Section 8.

      7.    EFFECT OF TERMINATION OF SERVICE.

            1.    OPTION EXERCISABILITY.

                  (a)   DISABILITY. If the Optionee's Service 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 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 three (3) months after the
Optionee's termination of Service.

                  (c)   OTHER TERMINATION OF SERVICE. If the Optionee's Service
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.

            2.    ADDITIONAL LIMITATIONS ON OPTION EXERCISE. Notwithstanding the
provisions of Section 7.1, the Option may not be exercised after the Optionee's
termination of Service to the extent that the shares to be acquired upon
exercise of the Option would be subject to the Unvested Share Repurchase Option
as provided in Section 11. Except as the Company and the Optionee otherwise
agree, exercise of the Option pursuant to Section 7.1 following termination of
the Optionee's Service may not be made by delivery of a promissory note as
provided in Section 4.3.(a).

            3.    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
<PAGE>   21
provisions of Section 4.6, the Option shall remain exercisable until three (3)
months after the date the Optionee is notified 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 to the Optionee of any such delayed exercise.

            4.    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 (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. 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(s) as to the tax consequences to the Optionee of any such delayed
exercise.

            5.    LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service shall not be deemed to terminate if the Optionee takes any military
leave, sick leave, or other bona fide leave of absence approved by the Company
of ninety (90) days or less. In the event of a leave of absence in excess of
ninety (90) days, the Optionee's Service shall be deemed to terminate on the
ninety-first (91st) day of such leave unless the Optionee's right to return to
Service remains 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 Ratio.

      8.    TRANSFER OF CONTROL.

            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 "TRANSFER OF 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
<PAGE>   22
CORPORATION(S)"), as the case may be; provided, however, that neither an initial
public offering by the Company, nor an equity or convertible securities
financing by the Company shall be deemed an Ownership Change Event or Transfer
of Control for the purpose of any accelerated vesting provision of this Option
Agreement.. 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.

            2.    EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of an
eligible Transfer of Control, the Vested Ratio shall be increased by two-fifths
(2/5) as of the date ten (10) days prior to the date of any such eligible
Transfer of Control; provided, however, that in no event shall the Vested Ratio
be increased pursuant to this Section 8.2 to a ratio in excess of one (1). The
exercise or vesting of any Option that was permissible solely by reason of this
Section 8.2 shall be conditioned upon the consummation of the Transfer of
Control. In addition, 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 the
Option or substitute for the Option a substantially equivalent option for the
Acquiring Corporation's stock. For purposes of this Section 8.2, the Option
shall be deemed assumed if, following the Transfer of Control, the Option
confers the right to purchase, for each share of Stock subject to the Option
immediately prior to the Transfer of 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 Transfer of Control was entitled. The Option shall
terminate and cease to be outstanding effective as of the date of the Transfer
of Control to the extent that the Option is neither assumed or substituted for
by the Acquiring Corporation in connection with the Transfer of Control nor
exercised as of the date of the Transfer of Control. Notwithstanding the
foregoing, shares acquired upon exercise of the Option prior to the Transfer of
Control and any consideration received pursuant to the Transfer of Control with
respect to such shares shall continue to be subject to all applicable provisions
of this Option Agreement except as otherwise provided herein. Furthermore,
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 Transfer of 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.

      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 
<PAGE>   23
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.   UNVESTED SHARE REPURCHASE OPTION.

            1.    GRANT OF UNVESTED SHARE REPURCHASE OPTION. In the event the
Optionee's Service is terminated for any reason or no reason, with or without
cause, of if the Optionee, the Optionee's legal representative, or other holder
of shares acquired upon exercise of the Option attempts to sell, exchange,
transfer, pledge, or otherwise dispose of (other than pursuant to an Ownership
Change Event) any shares acquired upon exercise of the Option which exceed the
Vested Shares as defined in Section 11.2 below (the "Unvested Shares"), the
Company shall have the right to repurchase the Unvested Shares under the terms
and subject to the conditions set forth in this Section 11 (the "Unvested Share
Repurchase Option").

            2.    VESTED SHARES AND UNVESTED SHARES DEFINED. The "Vested Shares"
shall mean, on any given date, a number of shares of Stock equal to the Number
of Option Shares multiplied by the Vested Ratio determined as of such date and
rounded down to the nearest whole share. On such given date, the "Unvested
Shares" shall mean the number of shares of stock acquired upon exercise of the
Option which exceed the Vested Shares determined as of such date.

            3.    EXERCISE OF UNVESTED SHARE REPURCHASE OPTION. The Company may
exercise the Unvested Share Repurchase Option by written notice to the Optionee
within sixty (60) days after (a) termination of the Optionee's Service for
exercise of the Option, if later) or (b) the Company has received notice of the
attempted disposition of Unvested Shares. If the Company fails to give notice
within such sixty (60) day period, the Unvested Share Repurchase Option shall
terminate (unless the Company and the Optionee have extended the time for the
exercise of the Unvested Share Repurchase Option. The Unvested Share Repurchase
Option must be exercised, if at all, for all of the Unvested Shares, except as
the Company and the Optionee otherwise agree.

            4.    PAYMENT FOR SHARES AND RETURN OF SHARES TO COMPANY. The
Purchase price per share being repurchased by the Company shall be an amount
equal to the Optionee's original cost per share, as adjusted pursuant to Section
9 (the "Repurchase Price"). The Company shall pay the aggregate Repurchase Price
to the Optionee in cash within thirty (30) days after the date of the written
notice to the Optionee of the Company's exercise of the Unvested Share
Repurchase Option. For purposes of the foregoing, cancellation of any
indebtedness of the Optionee to any Participating Company shall be treated as
payment to the Optionee in cash to the extent of the unpaid principal and any
accrued interest. 
<PAGE>   24
The shares being repurchased shall be delivered to the Company by the Optionee
at the same time as the delivery of the Repurchase Price to the Optionee.

            5.    ASSIGNMENT OF UNVESTED SHARE REPURCHASE OPTION. The Company
shall have the right to assign the Unvested Share Repurchase Option at any time,
whether or not such option is then exercisable, to one or more persons as may be
selected by the Company.

            6.    OWNERSHIP CHANGE EVENT. Upon the occurrence of an Ownership
Change Event, any and all new, substituted or additional securities or other
property to which the Optionee is entitled by reason of the Optionee's ownership
of Unvested Shares shall be immediately subject to the Unvested Share Repurchase
Option and included in the terms "Stock" and "Unvested Shares" for all purposes
of the Unvested Share Repurchase Option with the same force and effect as the
Unvested Shares immediately prior to the Ownership Change Event. While the
aggregate Repurchase Price shall remain the same after such Ownership Change
Event, the Repurchase Price per Unvested Share upon exercise of the Unvested
Share Repurchase Option following such Ownership Change Event shall be adjusted
as appropriate. For purposes of determining the Vested Ratio following an
Ownership Change Event, credited Service shall include all Service with any
corporation which is a Participating Company at the time the Service is
rendered, whether or not such corporation is a Participating Company both before
and after the Ownership Change Event. The foregoing notwithstanding, in the
event of an Ownership Change Event that is also a Transfer of Control, the
Unvested Share Repurchase Option will terminate if the surviving corporation
does not assume, or substitute substantially equivalent options for, all
outstanding Options under the Plan.

      12.   RIGHT OF FIRST REFUSAL.

            1.    GRANT OF RIGHT OF FIRST REFUSAL. Except as provided in Section
12.7 below, in the event the Optionee, the Optionee's legal representative, or
other holder of shares acquired upon exercise of the Option proposes to sell,
exchange, transfer, pledge, or otherwise dispose of any Vested Shares (the
"TRANSFER SHARES") to any person or entity, including, without limitation, any
shareholder of the Participating Company Group, the Company shall have the right
to repurchase the Transfer Shares under the terms and subject to the conditions
set forth in this Section 12 (the "RIGHT OF FIRST REFUSAL").

            2.    NOTICE OF PROPOSED TRANSFER. Prior to any proposed transfer of
the Transfer Shares, the Optionee shall deliver written notice (the "TRANSFER
NOTICE") to the Company describing fully the proposed transfer, including the
number of Transfer Shares, the name and address of the proposed transferee (the
"PROPOSED TRANSFEREE") and, if the transfer is voluntary, the proposed transfer
price, and containing such information necessary to show the bona fide nature of
the proposed transfer. In the event of a bona fide gift or involuntary transfer,
the proposed transfer price shall be deemed to be the Fair Market Value of the
Transfer Shares, as determined by the Board in good faith. If the Optionee
proposes to transfer any Transfer Shares to more than one Proposed Transferee,
the Optionee shall provide a separate Transfer Notice for the proposed transfer
to each Proposed Transferee. The Transfer Notice shall be signed by both the
Optionee and the Proposed Transferee and must constitute a binding commitment of
the Optionee and the Proposed Transferee for the transfer of the Transfer Shares
to the Proposed Transferee subject only to the Right of First Refusal.

            3.    BONA FIDE TRANSFER. If the Company determines that the
information provided by the Optionee in the Transfer Notice is insufficient to
establish the bona fide nature of a proposed voluntary transfer, the Company
shall give the Optionee written notice of the Optionee's failure to comply with
the procedure described in this Section 12, and the Optionee shall have no right
to transfer 
<PAGE>   25
the Transfer Shares without first complying with the procedure described in this
Section 12. The Optionee shall not be permitted to transfer the Transfer Shares
if the proposed transfer is not bona fide.

            4.    EXERCISE OF RIGHT OF FIRST REFUSAL. If the Company determines
the proposed transfer to be bona fide, the Company shall have the right to
purchase all, but not less than all, of the Transfer Shares (except as the
Company and the Optionee otherwise agree) at the purchase price and on the terms
set forth in the Transfer Notice by delivery to the Optionee of a notice of
exercise of the Right of First Refusal within thirty (30) days after the date
the Transfer Notice is delivered to the Company. The Company's exercise or
failure to exercise the Right of First Refusal with respect to any proposed
transfer described in a Transfer Notice shall not affect the Company's right to
exercise the Right of First Refusal with respect to any proposed transfer
described in any other Transfer Notice, whether or not such other Transfer
Notice is issued by the Optionee or issued by a person other than the Optionee
with respect to a proposed transfer to the same Proposed Transferee. If the
Company exercises the Right of First Refusal, the Company and the Optionee shall
thereupon consummate the sale of the Transfer Shares to the Company on the terms
set forth in the Transfer Notice within sixty (60) days after the date the
Transfer Notice is delivered to the Company (unless a longer period is offered
by the Proposed Transferee); provided, however, that in the event the Transfer
Notice provides for the payment for the Transfer Shares other than in cash, the
Company shall have the option of paying for the Transfer Shares by the present
value cash equivalent of the consideration described in the Transfer Notice as
reasonably determined by the Company. For purposes of the foregoing,
cancellation of any indebtedness of the Optionee to any Participating Company
shall be treated as payment to the Optionee in cash to the extent of the unpaid
principal and any accrued interest canceled.

            5.    FAILURE TO EXERCISE RIGHT OF FIRST REFUSAL. If the Company
fails to exercise the Right of First Refusal in full (or to such lesser extent
as the Company and the Optionee otherwise agree) within the period specified in
Section 12.4 above, the Optionee may conclude a transfer to the Proposed
Transferee of the Transfer Shares on the terms and conditions described in the
Transfer Notice, provided such transfer occurs not later than ninety (90) days
following delivery to the Company of the Transfer Notice. The Company shall have
the right to demand further assurances from the Optionee and the Proposed
Transferee (in a form satisfactory to the Company) that the transfer of the
Transfer Shares was actually carried out on the terms and conditions described
in the Transfer Notice. No Transfer Shares shall be transferred on the books of
the Company until the Company has received such assurances, if so demanded, and
has approved the proposed transfer as bona fide. Any proposed transfer on terms
and conditions different from those described in the Transfer Notice, as well as
any subsequent proposed transfer by the Optionee, shall again be subject to the
Right of First Refusal and shall require compliance by the Optionee with the
procedure described in this Section 12.

            6.    TRANSFEREES OF TRANSFER SHARES. All transferees of the
Transfer Shares or any interest therein, other than the Company, shall be
required as a condition of such transfer to agree in writing (in a form
satisfactory to the Company) that such transferee shall receive and hold such
Transfer Shares or interest therein subject to all of the terms and conditions
of this Option Agreement, including this Section 12 providing for the Right of
First Refusal with respect to any subsequent transfer. Any sale or transfer of
any shares acquired upon exercise of the Option shall be void unless the
provisions of this Section 12 are met.

            7.    TRANSFERS NOT SUBJECT TO RIGHT OF FIRST REFUSAL. The Right of
First Refusal shall not apply to any transfer or exchange of the shares acquired
upon exercise of the Option if such transfer or exchange is in connection with
an Ownership Change Event. If the consideration received pursuant to such
transfer or exchange consists of stock of a Participating Company, such
consideration
<PAGE>   26
shall remain subject to the Right of First Refusal unless the provisions of
Section 12.9 below result in a termination of the Right of First Refusal.

            8.    ASSIGNMENT OF RIGHT OF FIRST REFUSAL. The Company shall have
the right to assign the Right of First Refusal at any time, whether or not there
has been an attempted transfer, to one or more persons as may be selected by the
Company.

            9.    EARLY TERMINATION OF RIGHT OF FIRST REFUSAL. The other
provisions of this Option Agreement notwithstanding, the Right of First Refusal
shall terminate and be of no further force and effect upon (a) the occurrence of
a Transfer of Control, unless the Acquiring Corporation assumes the Company's
rights and obligations under the Option or substitutes a substantially
equivalent option for the Acquiring Corporation's stock for the Option, or (b)
the existence of a public market for the class of shares subject to the Right of
First Refusal. A "PUBLIC MARKET" shall be deemed to exist if (i) such stock is
listed on a national securities exchange (as that term is used in the Exchange
Act) or (ii) such stock is traded on the over-the-counter market and prices
therefor are published daily on business days in a recognized financial journal.

      13.   ESCROW.

            1.    ESTABLISHMENT OF ESCROW. To ensure that shares of Stock
obtained upon exercise of this Option which are subject to the Unvested Share
Repurchase Option, the Right of First Refusal or securing any promissory note
will be available for repurchase, the Company may require the Optionee to
deposit the certificate evidencing the shares of Stock which the Optionee
purchases upon exercise of the Option with an escrow agent designated by the
Company under the terms and conditions of an escrow and security agreements
approved by the Company. If the Company does not require such deposit as a
condition of exercise of the Option, the Company reserves the right at any time
to require the Optionee to so deposit the certificate in escrow. Upon the
occurrence of an Ownership Change Event or a change, as described in Section 9,
in the character or amount of any of the outstanding stock of the corporation
the stock of which is subject to the provisions of this Option Agreement, any
and all new, substituted or additional securities or other property to which the
Optionee is entitled by reason of the Optionee's ownership of shares of Stock
acquired upon exercise of the Option that remain, following such Ownership
Change Event or change described in Section 9, subject to the Unvested Share
Repurchase Option Right of First Refusal or any security interest held by the
Company shall be immediately subject to the escrow to the same extent as such
shares of Stock immediately before such event. The Company shall bear the
expenses of the escrow.

            2.    DELIVERY OF SHARES TO OPTIONEE. As soon as practicable after
the expiration of the Unvested Share Repurchase Option, the Right of First
Refusal and after full repayment of any promissory note secured by the option
shares of Stock or other property in escrow, but not more frequently than twice
each calendar year, the escrow agent shall deliver to the Optionee the shares of
Stock and any other property no longer subject to such restrictions and no
longer securing any promissory note.

            3.    NOTICES AND PAYMENTS. In the event the shares of Stock and any
other property held in escrow are subject to the Company's exercise of the
Unvested Share Repurchase Option, the Right of First Refusal, or any security
interest of the Company, the notices required to be given to the Optionee shall
be given to the escrow agent, and any payment required to be given to the
Optionee shall be given to the escrow agent. Within thirty (30) days after
payment by the Company, the escrow agent shall deliver the shares of Stock and
any other property which the Company has purchased to the Company and shall
deliver the payment received from the Company to the Optionee.
<PAGE>   27
      14.   STOCK DISTRIBUTIONS SUBJECT TO OPTION AGREEMENT. If, from time to
time, there is any stock dividend, stock split or other change, as described in
Section 9, in the character or amount of any of the outstanding stock of the
corporation the stock of which is subject to the provisions of this Option
Agreement, then in such event any and all new, substituted or additional
securities to which the Optionee is entitled by reason of the Optionee's
ownership of the shares acquired upon exercise of the Option shall be
immediately subject to the Unvested Share Repurchase Option, Right of First
Refusal and any security interest held by the Company and with the same force
and effect as the shares subject to the Unvested Share Repurchase Option, Right
of First Refusal and any such security interest immediately before such event.

      15.   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 the Optionee exercises all or part of the Option or within
two (2) years after the Date of Option Grant and shall provide the Company with
a description of the terms and circumstances of such disposition. 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 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.

      16.   LEGENDS. The Company may at any time place legends referencing the
Unvested Share Repurchase Option, the Right of First Refusal, any security
interest and 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. Unless otherwise specified by
the Company, legends placed on such certificates may include, but shall not be
limited to, the following:

            1.    "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD,
TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN
OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO
THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS
EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT."

            2.    Any legend required to be placed thereon by the Commissioner
of Corporations of the State of California.

            3.    "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN
UNVESTED SHARE REPURCHASE OPTION IN FAVOR OF THE CORPORATION OR ITS 
<PAGE>   28
ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED
HOLDER, OR SUCH HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT
THE PRINCIPAL OFFICE OF THIS CORPORATION."

RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET
FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH
HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
OFFICE OF THIS CORPORATION."

      17.   PUBLIC OFFERING. The Optionee hereby agrees that in the event of any
underwritten public offering of stock, including an initial 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 at its sole discretion. 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.

      18.   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 Option Agreement and,
except pursuant to an Ownership Change, until the date on which such shares
become Vested Shares, 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 Option
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.

      19.   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.

      20.   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 Transfer of 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.

      21.   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,

otherwise indicated by the context, the singular shall include the plural, the
plural shall include the singular, and the term "or" shall include the
conjunctive as well as the disjunctive.

      2.    TAX CONSEQUENCES.

            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 (an
"INCENTIVE STOCK OPTION"), 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: 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 held by the Optionee (whether granted pursuant to the
Plan or any other stock option plan of the Participating Company Group) is
greater than One Hundred Thousand Dollars ($100,000), the Optionee should
contact the Chief Financial Officer of the Company to ascertain whether the
entire Option qualifies as an Incentive Stock Option.)

            2     ELECTION UNDER SECTION 83(b) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk of forfeiture, the Optionee understands that
the Optionee should consult with the Optionee's tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under
Section 83(b) of the Code, which must be filed no later than thirty (30) days
after the date on which the Optionee exercises the Option. Shares acquired upon
exercise of the Option are nontransferable and subject to a substantial risk of
forfeiture if, for example, (a) they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee's original purchase price
if the Optionee's Service terminates, (b) the Optionee is an Insider and
exercises the Option within six (6) months of the Date of Option Grant (if a
class of equity security of the Company is registered under Section 12 of the
Exchange Act), or (c) the Optionee is subject to a restriction on transfer to
comply with "Pooling-of-Interests Accounting" rules. Failure to file an election
under Section 83(b), if appropriate, may result in adverse tax consequences to
the Optionee. The Optionee acknowledges that the Optionee has been advised to
consult with a tax advisor prior to the exercise of the Option regarding the tax
consequences to the Optionee of the exercise of the Option. AN ELECTION UNDER
SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH THE OPTIONEE
PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE OPTIONEE ACKNOWLEDGES
THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE OPTIONEE'S SOLE
RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE
TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

      3.    ADMINISTRATION. All questions of interpretation concerning this
Option Agreement shall be determined by the Board, including any duly appointed
Committee of 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.
<PAGE>   34
      4.    EXERCISE OF THE OPTION.

            1     RIGHT TO EXERCISE.

                  (a)   Except as otherwise provided herein, the Option shall be
exercisable on and after the Initial Exercise Date and prior to the termination
of the Option (as provided in Section 6) in an amount not to exceed the Number
of Option Shares less the number of shares of Stock previously acquired upon
exercise of the Option, subject to the Optionee's agreement that any shares
purchased upon exercise are subject to the Company's repurchase rights set forth
in Section 11 and to the Company's first refusal rights set forth in Section 12.
In no event shall the Option be exercisable for more shares than the Number of
Option Shares. Notwithstanding the foregoing, except as provided in Section
4.1(b), 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 any
calendar year, 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, shall not exceed
One Hundred Thousand Dollars ($100,000). 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. Such limitation on exercise shall be referred to in this Option
Agreement as the "ISO Exercise Limitation." If Section 422 of the Code is
amended to provide for a different limitation from that set forth in this
Section 4.1(a), the ISO Exercise Limitation shall be deemed amended effective as
of the date required or permitted by such amendment to the Code. The ISO
Exercise Limitation shall terminate upon the earlier of (i) the Optionee's
termination of Service, (ii) the day immediately prior to the effective date of
a Transfer of Control in which the Option is not assumed or substituted for by
the Acquiring Corporation as provided in Section 8, or (iii) the day ten (10)
days prior to the Option Expiration Date. Upon such termination of the ISO
Exercise Limitation, the Option shall be deemed a Nonstatutory Stock Option to
the extent of the number of shares subject to the Option which would otherwise
exceed the ISO Exercise Limitation.

                  (b)   Notwithstanding any other provision of this Option
Agreement, if compliance with the ISO Exercise Limitation as set forth in
Section 4.1(a) will result in the exercisability of any Vested Shares (as
defined in Section 11.2) being delayed more than thirty (30) days beyond the
date such shares become Vested (the "Vesting Date"), the Option shall be deemed
to be two (2) options. The fist option shall be for the maximum portion of the
Number of Option Shares that can comply with the ISO Exercise Limitation without
causing the Option to be unexercisable in the aggregate as to Vested Shares on
the Vesting Date for such shares. The second option, which shall not be treated
as an Incentive Stock Option as described in Section 422(b) of the Code, shall
be for the balance of the Number of Option Shares: that is, those such shares
which, on the respective Vesting Date for such shares, would be unexercisable if
included in the first option and thereby made subject to the ISO Exercise
Limitation. Shares treated as subject to the second option shall be exercisable
on the same terms and at the same time as set forth in this Option Agreement;
provided, however, that (i) the third sentence of Section 4.1(a) shall not apply
to the second option and (ii) each such share shall become a Vested Share on the
Vesting Date on which such shares must first be allocated to the second option
pursuant to the preceding sentence. Unless the Optionee specifically elects to
the contrary in the Optionee's written notice of exercise, the first option
shall be deemed to be exercise first to the maximum possible extent and then the
second option shall be deemed to be exercised.

            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 
<PAGE>   35
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 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 6,
accompanied by (i) full payment of the aggregate Exercise Price for the number
of shares of Stock being purchased and (ii) an executed copy, if required
herein, of the then current forms of escrow and security agreement referenced
below. The Option shall be deemed to be exercised upon receipt by the Company of
such written notice, the aggregate Exercise Price, and, if required by the
Company, such executed agreements.

            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 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(c), (iv) in the
Company's sole discretion at the time the Option is exercised, by cash for a
portion of the aggregate Exercise Price not less than the par value of the
shares being acquired, and the Optionee's promissory note for the balance of the
aggregate Exercise Price, or (v) by any combination of the foregoing.

                  (b)   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 shares 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.

                  (c)   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 establish,
modify, decline to approve or terminate any such program or procedures.

                  (d)   PAYMENT BY PROMISSORY NOTE. No promissory note shall be
permitted if an exercise of the Option using a promissory note would be a
violation of any law. The promissory note permitted in clause (iv) of Section
4.3(a) shall be a full recourse note in a form satisfactory to the Company, with
principal payable no more than four (4) years after the date the Option is
exercised. Interest on the principal balance of the promissory note shall be
payable in annual installments at the minimum interest rate necessary to avoid
imputed interest pursuant to all applicable sections of the Code. Such recourse
promissory note shall be secured by the shares of Stock acquired pursuant to the
then current form of security agreement as approved by the Company. At any time
the Company 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
<PAGE>   36
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. Except as the Company in
its sole discretion shall determine, the Optionee shall pay the unpaid principal
balance of the promissory note and any accrued interest thereon upon termination
of the Optionee's Service with the Participating Company Group for any reason,
with or without cause.

            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 such tax withholding obligations 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 or release such shares from any escrow provided for
herein.

            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.

            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 shares of 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. 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.

            7     FRACTIONAL SHARES. The Company shall not be required to issue
fractional shares upon the exercise of the Option.
<PAGE>   37
      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 Transfer of Control to the extent
provided in Section 8.

      7.    EFFECT OF TERMINATION OF SERVICE.

            1     OPTION EXERCISABILITY.

                  (a)   DISABILITY. If the Optionee's Service 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. (NOTE: If the Option is exercised more than three (3)
months after the date on which the Optionee's Service as an Employee terminated
as a result of a Disability other than a 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.

                  (b)   DEATH. If the Optionee's Service 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 three (3) months after the
Optionee's termination of Service.

                  (c)   OTHER TERMINATION OF SERVICE. If the Optionee's Service
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.

            2     ADDITIONAL LIMITATIONS ON OPTION EXERCISE. Notwithstanding the
provisions in Section 7.1, the Option may not be exercised after the Optionee's
termination of Service to the extent that the shares to be acquired upon
exercise of the Option would be subject to the Unvested Share Repurchase Option
as provided in Section 11. Except as the Company and the Optionee otherwise
agree, exercise of the Option pursuant to Section 7.1 following termination of
the Optionee's Service may not be made by delivery of a promissory note as
provided in Section 4.3(a).
<PAGE>   38
            3     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 three (3) months after the date the Optionee is
notified 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 to the Optionee of any
such delayed exercise.

            4     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 (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. 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(s) as to the tax consequences to the Optionee of any such delayed
exercise.

            5     LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service shall not be deemed to terminate if the Optionee takes any military
leave, sick leave, or other bona fide leave of absence approved by the Company
of ninety (90) days or less. In the event of a leave of absence in excess of
ninety (90) days, the Optionee's Service shall be deemed to terminate on the
ninety-first (91st) day of such leave unless the Optionee's right to return to
Service remains 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 Ratio.

      8.    TRANSFER OF CONTROL.

            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 "TRANSFER OF 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 
<PAGE>   39
(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;
provided, however, that neither an initial public offering by the Company, nor
an equity or convertible securities financing by the Company shall be deemed an
Ownership Change Event or Transfer of Control for the purpose of any accelerated
vesting provision of this Option Agreement. 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.

            2     EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of an
eligible Transfer of Control, the Vested Ratio shall be increased by two-fifths
(2/5) as of the date ten (10) days prior to the date of any such eligible
Transfer of Control; provided, however, that in no event shall the Vested Ratio
be increased pursuant to this Section 8.2 to a ratio in excess of one (1). The
exercise or vesting of any Option that was permissible solely by reason of this
Section 8.2 shall be conditioned upon the consummation of the Transfer of
Control. In addition, 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 the
Option or substitute for the Option a substantially equivalent option for the
Acquiring Corporation's stock. For purposes of this Section 8.2, the Option
shall be deemed assumed if, following the Transfer of Control, the Option
confers the right to purchase, for each share of Stock subject to the Option
immediately prior to the Transfer of 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 Transfer of Control was entitled. The Option shall
terminate and cease to be outstanding effective as of the date of the Transfer
of Control to the extent that the Option is neither assumed or substituted for
by the Acquiring Corporation in connection with the Transfer of Control nor
exercised as of the date of the Transfer of Control. Notwithstanding the
foregoing, shares acquired upon exercise of the Option prior to the Transfer of
Control and any consideration received pursuant to the Transfer of Control with
respect to such shares shall continue to be subject to all applicable provisions
of this Option Agreement except as otherwise provided herein. Furthermore,
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 Transfer of 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.

      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 
<PAGE>   40
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.   UNVESTED SHARE REPURCHASE OPTION.

            1     GRANT OF UNVESTED SHARE REPURCHASE OPTION. In the event the
Optionee's Service is terminated for any reason or no reason, with or without
cause, or if the Optionee, the Optionee's legal representative, or other holder
of shares acquired upon exercise of the Option attempts to sell, exchange,
transfer, pledge, or otherwise dispose of (other than pursuant to an Ownership
Change Event) any shares acquired upon exercise of the Option which exceed the
Vested Shares as defined in Section 11.2 below (the "Unvested Shares"), the
Company shall have the right to repurchase the Unvested Shares under the terms
and subject to the conditions set forth in this Section 11 (the "Unvested Share
Repurchase Option").

            2     VESTED SHARES AND UNVESTED SHARES DEFINED. The "Vested Shares"
shall mean, on any given date, a number of shares of Stock equal to the Number
of Option Shares multiplied by the Vested Ratio determined as of such date and
rounded down to the nearest whole share. On such given date, the "Unvested
Shares" shall mean the number of shares of Stock acquired upon exercise of the
Option which exceed the Vested Shares determined as of such date.

            3     EXERCISE OF UNVESTED SHARE REPURCHASE OPTION. The Company may
exercise the Unvested Share Repurchase Option by written notice to the Optionee
within sixty (60) days after (a) termination of the Optionee's Service (or
exercise of the Option, if later) or (b) the Company has received notice of the
attempted disposition of Unvested Shares. If the Company fails to give notice
within such sixty (60) day period, the Unvested Share Repurchase Option shall
terminate unless the Company and the Optionee have extended the time for the
exercise of the Unvested Share Repurchase Option. The Unvested Share Repurchase
Option must be exercised, if at all, for all of the Unvested Shares, except as
the Company and the Optionee otherwise agree.

            4     PAYMENT FOR SHARES AND RETURN OF SHARES TO COMPANY. The
purchase price per share being repurchased by the Company shall be an amount
equal to the Optionee's original cost per share, as adjusted pursuant to Section
9 (the "Repurchase Price"). The Company shall pay the aggregate Repurchase Price
to the Optionee in cash within thirty (30) days after the date of the written
notice to the Optionee of the Company's exercise of the Unvested Share
Repurchase Option. For purposes of the foregoing, cancellation of any
indebtedness of the Optionee to any Participating Company shall be 
<PAGE>   41
treated as payment to the Optionee in cash to the extent of the unpaid principal
and any accrued interest canceled. The shares being repurchased shall be
delivered to the Company by the Optionee at the same time as the delivery of the
Repurchase Price to the Optionee.

            5     ASSIGNMENT OF UNVESTED SHARE REPURCHASE OPTION. The Company
shall have the right to assign the Unvested Share Repurchase Option at any time,
whether or not such option is then exercisable, to one or more persons as may be
selected by the Company.

            6     OWNERSHIP CHANGE EVENT. Upon the occurrence of an Ownership
Change Event, any and all new, substituted or additional securities or other
property to which the Optionee is entitled by reason of the Optionee's ownership
of Unvested Shares shall be immediately subject to the Unvested Share Repurchase
Option and included in the terms "Stock" and "Unvested Shares" for all purposes
of the Unvested Share Repurchase Option with the same force and effect as the
Unvested Shares immediately prior to the Ownership Change Event. While the
aggregate Repurchase Price shall remain the same after such Ownership Change
Event, the Repurchase Price per Unvested Share upon exercise of the Unvested
Share Repurchase Option following such Ownership Change Event shall be adjusted
as appropriate. For purposes of determining the Vested Ratio following an
Ownership Change Event, credited Service shall include all Service with any
corporation which is a Participating Company at the time the Service is
rendered, whether or not such corporation is a Participating Company both before
and after the Ownership Change Event. The foregoing notwithstanding, in the
event of an Ownership Change Event that is also a Transfer of Control, the
Unvested Share Repurchase Option will terminate if the surviving corporation
does not assume, or substitute substantially equivalent options for, all
outstanding Options under the Plan.

      12.   RIGHT OF FIRST REFUSAL.

            1     GRANT OF RIGHT OF FIRST REFUSAL. Except as provided in Section
12.7 below, in the event the Optionee, the Optionee's legal representative, or
other holder of shares acquired upon exercise of the Option proposes to sell,
exchange, transfer, pledge, or otherwise dispose of any Vested Shares (the
"TRANSFER SHARES") to any person or entity, including, without limitation, any
shareholder of the Participating Company Group, the Company shall have the right
to repurchase the Transfer Shares under the terms and subject to the conditions
set forth in this Section 12 (the "RIGHT OF FIRST REFUSAL").

            2     NOTICE OF PROPOSED TRANSFER. Prior to any proposed transfer of
the Transfer Shares, the Optionee shall deliver written notice (the "TRANSFER
NOTICE") to the Company describing fully the proposed transfer, including the
number of Transfer Shares, the name and address of the proposed transferee (the
"PROPOSED TRANSFEREE") and, if the transfer is voluntary, the proposed transfer
price, and containing such information necessary to show the bona fide nature of
the proposed transfer. In the event of a bona fide gift or involuntary transfer,
the proposed transfer price shall be deemed to be the Fair Market Value of the
Transfer Shares, as determined by the Board in good faith. If the Optionee
proposes to transfer any Transfer Shares to more than one Proposed Transferee,
the Optionee shall provide a separate Transfer Notice for the proposed transfer
to each Proposed Transferee. The Transfer Notice shall be signed by both the
Optionee and the Proposed Transferee and must constitute a binding commitment of
the Optionee and the Proposed Transferee for the transfer of the Transfer Shares
to the Proposed Transferee subject only to the Right of First Refusal.

            3     BONA FIDE TRANSFER. If the Company determines that the
information provided by the Optionee in the Transfer Notice is insufficient to
establish the bona fide nature of a proposed voluntary transfer, the Company
shall give the Optionee written notice of the Optionee's failure to comply with
the procedure described in this Section 12, and the Optionee shall have no right
to transfer
<PAGE>   42
the Transfer Shares without first complying with the procedure described in this
Section 12. The Optionee shall not be permitted to transfer the Transfer Shares
if the proposed transfer is not bona fide.

            4     EXERCISE OF RIGHT OF FIRST REFUSAL. If the Company determines
the proposed transfer to be bona fide, the Company shall have the right to
purchase all, but not less than all, of the Transfer Shares (except as the
Company and the Optionee otherwise agree) at the purchase price and on the terms
set forth in the Transfer Notice by delivery to the Optionee of a notice of
exercise of the Right of First Refusal within thirty (30) days after the date
the Transfer Notice is delivered to the Company. The Company's exercise or
failure to exercise the Right of First Refusal with respect to any proposed
transfer described in a Transfer Notice shall not affect the Company's right to
exercise the Right of First Refusal with respect to any proposed transfer
described in any other Transfer Notice, whether or not such other Transfer
Notice is issued by the Optionee or issued by a person other than the Optionee
with respect to a proposed transfer to the same Proposed Transferee. If the
Company exercises the Right of First Refusal, the Company and the Optionee shall
thereupon consummate the sale of the Transfer Shares to the Company on the terms
set forth in the Transfer Notice within sixty (60) days after the date the
Transfer Notice is delivered to the Company (unless a longer period is offered
by the Proposed Transferee); provided, however, that in the event the Transfer
Notice provides for the payment for the Transfer Shares other than in cash, the
Company shall have the option of paying for the Transfer Shares by the present
value cash equivalent of the consideration described in the Transfer Notice as
reasonably determined by the Company. For purposes of the foregoing,
cancellation of any indebtedness of the Optionee to any Participating Company
shall be treated as payment to the Optionee in cash to the extent of the unpaid
principal and any accrued interest canceled.

            5     FAILURE TO EXERCISE RIGHT OF FIRST REFUSAL. If the Company
fails to exercise the Right of First Refusal in full (or to such lesser extent
as the Company and the Optionee otherwise agree) within the period specified in
Section 12.4 above, the Optionee may conclude a transfer to the Proposed
Transferee of the Transfer Shares on the terms and conditions described in the
Transfer Notice, provided such transfer occurs not later than ninety (90) days
following delivery to the Company of the Transfer Notice. The Company shall have
the right to demand further assurances from the Optionee and the Proposed
Transferee (in a form satisfactory to the Company) that the transfer of the
Transfer Shares was actually carried out on the terms and conditions described
in the Transfer Notice. No Transfer Shares shall be transferred on the books of
the Company until the Company has received such assurances, if so demanded, and
has approved the proposed transfer as bona fide. Any proposed transfer on terms
and conditions different from those described in the Transfer Notice, as well as
any subsequent proposed transfer by the Optionee, shall again be subject to the
Right of First Refusal and shall require compliance by the Optionee with the
procedure described in this Section 12.

            6     TRANSFEREES OF TRANSFER SHARES. All transferees of the
Transfer Shares or any interest therein, other than the Company, shall be
required as a condition of such transfer to agree in writing (in a form
satisfactory to the Company) that such transferee shall receive and hold such
Transfer Shares or interest therein subject to all of the terms and conditions
of this Option Agreement, including this Section 12 providing for the Right of
First Refusal with respect to any subsequent transfer. Any sale or transfer of
any shares acquired upon exercise of the Option shall be void unless the
provisions of this Section 12 are met.

            7     TRANSFERS NOT SUBJECT TO RIGHT OF FIRST REFUSAL. The Right of
First Refusal shall not apply to any transfer or exchange of the shares acquired
upon exercise of the Option if such transfer or exchange is in connection with
an Ownership Change Event. If the consideration received pursuant to such
transfer or exchange consists of stock of a Participating Company, such
consideration shall remain 
<PAGE>   43
subject to the Right of First Refusal unless the provisions of Section 12.9
below result in a termination of the Right of First Refusal.

            8     ASSIGNMENT OF RIGHT OF FIRST REFUSAL. The Company shall have
the right to assign the Right of First Refusal at any time, whether or not there
has been an attempted transfer, to one or more persons as may be selected by the
Company.

            9     EARLY TERMINATION OF RIGHT OF FIRST REFUSAL. The other
provisions of this Option Agreement notwithstanding, the Right of First Refusal
shall terminate and be of no further force and effect upon (a) the occurrence of
a Transfer of Control, unless the Acquiring Corporation assumes the Company's
rights and obligations under the Option or substitutes a substantially
equivalent option for the Acquiring Corporation's stock for the Option, or (b)
the existence of a public market for the class of shares subject to the Right of
First Refusal. A "PUBLIC MARKET" shall be deemed to exist if (i) such stock is
listed on a national securities exchange (as that term is used in the Exchange
Act) or (ii) such stock is traded on the over-the-counter market and prices
therefor are published daily on business days in a recognized financial journal.

      13.   ESCROW.

            1     ESTABLISHMENT OF ESCROW. To ensure that shares of Stock issued
upon exercise of this Option which are subject to the Unvested Share Repurchase
Option, the Right of First Refusal or securing any promissory note will be
available for repurchase, the Company may require the Optionee to deposit the
certificate evidencing the shares of Stock which the Optionee purchases upon
exercise of the Option with an escrow agent designated by the Company under the
terms and conditions of an escrow and security agreements approved by the
Company. If the Company does not require such deposit as a condition of exercise
of the Option, the Company reserves the right at any time to require the
Optionee to so deposit the certificate in escrow. Upon the occurrence of an
Ownership Change Event or a change, as described in Section 9, in the character
or amount of any of the outstanding stock of the corporation the stock of which
is subject to the provisions of this Option Agreement, any and all new,
substituted or additional securities or other property to which the Optionee is
entitled by reason of the Optionee's ownership of shares of Stock acquired upon
exercise of the Option that remain, following such Ownership Change Event or
change described in Section 9, subject to the Unvested Share Repurchase Option,
the Right of First Refusal or any security interest held by the Company shall be
immediately subject to the escrow to the same extent as such shares of Stock
immediately before such event. The Company shall bear the expenses of the
escrow.

            2     DELIVERY OF SHARES TO OPTIONEE. As soon as practicable after
the expiration of the Unvested Share Repurchase Option, the Right of First
Refusal and after full repayment of any promissory note secured by the shares of
Stock or other property in escrow, but not more frequently than twice each
calendar year, the escrow agent shall deliver to the Optionee the shares of
Stock and any other property no longer subject to such restrictions and no
longer securing any promissory note.

            3     NOTICES AND PAYMENTS. In the event the shares of Stock and any
other property held in escrow are subject to the Company's exercise of the
Unvested Share Repurchase Option, the Right of First Refusal, or any security
interest of the Company, the notices required to be given to the Optionee shall
be given to the escrow agent, and any payment required to be given to the
Optionee shall be given to the escrow agent. Within thirty (30) days after
payment by the Company, the escrow agent shall deliver the shares of Stock and
any other property which the Company has purchased to the Company and shall
deliver the payment received from the Company to the Optionee.
<PAGE>   44
      14.   STOCK DISTRIBUTIONS SUBJECT TO OPTION AGREEMENT. If, from time to
time, there is any stock dividend, stock split or other change, as described in
Section 9, in the character or amount of any of the outstanding stock of the
corporation the stock of which is subject to the provisions of this Option
Agreement, then in such event any and all new, substituted or additional
securities to which the Optionee is entitled by reason of the Optionee's
ownership of the shares acquired upon exercise of the Option shall be
immediately subject to the Unvested Share Repurchase Option, the Right of First
Refusal and any security interest held by the Company and with the same force
and effect as the shares subject to the Unvested Share Repurchase Option, the
Right of First Refusal and any such security interest immediately before such
event.

      15.   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

year after the date the Optionee exercises all or part of the Option or within

two-year periods set forth above, the Company may place a legend on any
certificate representing shares acquired pursuant to the Option requesting 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

underwritten public offering of stock, including an initial public offering of
stock, made by the Company pursuant to an effective registration statement filed

become Vested Shares, 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 Option
Agreement or (b) to treat as owner of such shares or to accord the right to vote
