II. SECURITIES LAW COMPLIANCE 2.1 EXEMPTION FROM REGISTRATION. The Purchased Shares have not been
registered under the Securities Act of 1933, as amended (the 1933 Act), and
are accordingly being issued to Optionee in reliance upon the exemption from
such registration provided by Rule 701 of the Securities and Exchange Commission
(the SEC) for stock issuances under compensatory benefit plans such as the
Plan. Optionee hereby acknowledges previous receipt of a copy of the
documentation for such Plan in the form of Exhibit C to the Notice of Grant of
Stock Option (the Grant Notice) accompanying the Option Agreement. 2.2 RESTRICTED SECURITIES. A. Optionee hereby confirms that Optionee has been informed that the
Purchased Shares are restricted securities under the 1933 Act and may not be
resold or transferred unless the Purchased Shares are first registered under the
Federal securities laws or unless an exemption from such registration is
available. Accordingly, Optionee hereby acknowledges that Optionee is prepared
to hold the Purchased Shares for an indefinite period and that Optionee is aware
that Rule 144 of the SEC issued under the 1933 Act is not presently available to
exempt the sale of the Purchased Shares from the registration requirements of
the 1933 Act. B. Upon the expiration of the ninety (90)-day period immediately
following the date on which the Corporation first becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended (the
Exchange Act), the Purchased Shares, to the extent vested under Article V, may
be sold (without registration) pursuant to the applicable requirements of Rule
144. If Optionee is at the time of such sale an affiliate of the Corporation
for purposes of Rule 144 or was such an affiliate during the preceding three (3)
months, then the sale must comply with all the requirements of Rule 144
(including the volume limitation on the number of shares sold, the
broker/market-maker sale requirement and the requisite notice to the SEC);
however, the two (2)-year holding period requirement of the Rule will not be
applicable. If Optionee is not at the time of the sale an affiliate of the
Corporation nor was such an affiliate during the preceding three (3) months,
then none of the requirements of Rule 144 (other than the broker/market-maker
sale requirement for Purchased Shares held for less than three (3) years
following payment in cash of the Option Price therefor) will be applicable to
the sale. C. Should the Corporation not become subject to the reporting
requirements of the Exchange Act, then Optionee may, provided he/she is not at
the time an affiliate of the Corporation (nor was such an affiliate during the
preceding three (3) months), sell the Purchased Shares (without registration)
pursuant to paragraph (k) of Rule 144 after the Purchased Shares have been held
for a period of three (3) years following the payment in cash of the Option
Price for such shares. 2.

##### 



2.3 DISPOSITION OF SHARES. Optionee hereby agrees that Optionee
shall make no disposition of the Purchased Shares (other than a permitted
transfer under paragraph 4.1) unless and until there is compliance with all of
the following requirements: (a) Optionee shall have notified the Corporation of the proposed
disposition and provided a written summary of the terms and conditions of
the proposed disposition. (b) Optionee shall have complied with all requirements of this
Agreement applicable to the disposition of the Purchased Shares. (c) Optionee shall have provided the Corporation with written
assurances, in form and substance satisfactory to the Corporation, that (i)
the proposed disposition does not require registration of the Purchased
Shares under the 1933 Act or (ii) all appropriate action necessary for
compliance with the registration requirements of the 1933 Act or of any
exemption from registration available under the 1933 Act (including Rule
144) has been taken. (d) Optionee shall have provided the Corporation with written
assurances, in form and substance satisfactory to the Corporation, that the
proposed disposition will not result in the contravention of any transfer
restrictions applicable to the Purchased Shares pursuant to the provisions
of the Commissioner Rules identified in paragraph 2.5. The Corporation shall NOT be required (i) to transfer on its books any
Purchased Shares which have been sold or transferred in violation of the
provisions of this Article II NOR (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting or dividend rights to, any transferee to
whom the Purchased Shares have been transferred in contravention of this
Agreement. 2.4 RESTRICTIVE LEGENDS. In order to reflect the restrictions on
disposition of the Purchased Shares, the stock certificates for the Purchased
Shares will be endorsed with restrictive legends, including one or more of the
following legends: (i) The shares represented by this certificate have not been
registered under the Securities Act of 1933. The shares may not be sold or
offered for sale in the absence of (a) an effective registration statement for
the shares under such Act, (b) a no action letter of the SEC with respect to
such sale or offer, or (c) satisfactory assurances to the Corporation that
registration under such Act is not required with respect to such sale or offer. 3.

(ii) It is unlawful to consummate a sale or transfer of this
security, or any interest therein, or to receive any consideration therefor,
without the prior written consent of the Commissioner of Corporations of the
State of California, except as permitted in the Commissioners Rules. (iii) The shares represented by this certificate are unvested and
accordingly may not be sold, assigned, transferred, encumbered, or in any manner
disposed of except in conformity with the terms of a written agreement dated
_________, 19____between the Corporation and the registered holder of the
shares (or the predecessor in interest to the shares). Such agreement grants
certain repurchase rights and rights of first refusal to the Corporation (or its
assignees) upon the sale, assignment, transfer, encumbrance or other disposition
of the Corporations shares or upon termination of service with the Corporation.
The Corporation will upon written request furnish a copy of such agreement to
the holder hereof without charge. 2.5 RECEIPT OF COMMISSIONER RULES. Optionee hereby acknowledges
receipt of a copy of Section 260.141.11 of the Rules of the California
Corporations Commissioner, a copy of which is attached as Exhibit II to this
Agreement. III. SPECIAL TAX ELECTION 3.1 SECTION 83(B) ELECTION APPLICABLE TO THE EXERCISE OF A NON-
STATUTORY STOCK OPTION. If the Purchased Shares are acquired hereunder pursuant
to the exercise of a NON-STATUTORY STOCK OPTION, as specified in the Grant
Notice, then the Optionee understands that under Section 83 of the Internal
Revenue Code of 1986, as amended (the Code), the excess of the fair market
value of the Purchased Shares on the date any forfeiture restrictions applicable
to such shares lapse over the Option Price paid for such shares will be
reportable as ordinary income on such lapse date. For this purpose, the term
forfeiture restrictions includes the right of the Corporation to repurchase
the Purchased Shares pursuant to the Repurchase Right provided under Article V
of this Agreement. Optionee understands that he/she may elect under Section
83(b) of the Code to be taxed at the time the Purchased Shares are acquired
hereunder, rather than when and as such Purchased Shares cease to be subject to
such forfeiture restrictions. Such election must be filed with the Internal
Revenue Service within thirty (30) days after the date of this Agreement. Even
if the fair market value of the Purchased Shares at the date of this Agreement
equals the Option Price paid (and thus no tax is payable), the election must be
made to avoid adverse tax consequences in the future. THE FORM FOR MAKING THIS
ELECTION IS ATTACHED AS EXHIBIT III HERETO. OPTIONEE UNDERSTANDS THAT FAILURE
TO MAKE THIS FILING WITHIN THE THIRTY (30)-DAY PERIOD WILL RESULT IN THE
RECOGNITION OF ORDINARY INCOME BY THE OPTIONEE AS THE FORFEITURE RESTRICTIONS
LAPSE. 3.2 CONDITIONAL SECTION 83(B) ELECTION APPLICABLE TO THE EXERCISE OF
AN INCENTIVE STOCK OPTION. If the Purchased Shares are acquired hereunder
pursuant to the 4.




---



##### 



exercise of an INCENTIVE STOCK OPTION under the Federal tax laws, as specified
in the Grant Notice, then the following tax principles shall be applicable to
the Purchased Shares: A. For regular tax purposes, no taxable income will be
recognized at the time the Option is exercised. B. The excess of (i) the fair market value of the
Purchased Shares on the date the Option is exercised or (if later) on
the date any forfeiture restrictions applicable to the Purchased
Shares lapse over (ii) the Option Price paid for the Purchased Shares
will be includible in the Optionees taxable income for alternative
minimum tax purposes. C. If the Optionee makes a disqualifying disposition of
the Purchased Shares, then the Optionee will recognize ordinary income
in the year of such disposition equal in amount to the excess of (i)
the fair market value of the Purchased Shares on the date the Option
is exercised or (if later) on the date any forfeiture restrictions
applicable to the Purchased Shares lapse over (ii) the Option Price
paid for the Purchased Shares. Any additional gain recognized upon
the disqualifying disposition will be either short-term or long-term
capital gain depending upon the period for which the Purchased Shares
are held prior to the disposition. D. For purposes of the foregoing, the term forfeiture
restrictions will include the right of the Corporation to repurchase
the Purchased Shares pursuant to the Repurchase Right provided under
Article V of this Agreement. The term disqualifying disposition
means any sale or other disposition(1) of the Purchased Shares within
two (2) years after the Grant Date or within one (1) year after the
execution date of this Agreement. E. In the absence of final Treasury Regulations relating
to incentive stock options, it is not certain whether the Optionee
may, in connection with the exercise of the Option for any Purchased
Shares at the time subject to forfeiture restrictions, file a
protective election under Section 83(b) of the Code which would limit
(I) the Optionees alternative minimum taxable income upon exercise
and (II) the Optionees ordinary income upon a disqualifying
disposition, to the excess of (i) the fair market value of the
Purchased Shares on the date the Option is exercised over (ii) the
Option   (1)
    
    Generally, a disposition of shares purchased under an incentive stock
option includes any transfer of legal title, including a transfer by sale,
exchange or gift, but does not include a transfer to the Optionees spouse, a
transfer into joint ownership with right of survivorship if Optionee remains one
of the joint owners, a pledge, a transfer by bequest or inheritance or certain
tax free exchanges permitted under the Code. 5.

Price paid for the Purchased Shares. THE APPROPRIATE FORM FOR MAKING SUCH
A PROTECTIVE ELECTION IS ATTACHED AS EXHIBIT III TO THIS AGREEMENT AND MUST
BE FILED WITH THE INTERNAL REVENUE SERVICE WITHIN THIRTY (30) DAYS AFTER
THE DATE OF THIS AGREEMENT. HOWEVER, SUCH ELECTION IF PROPERLY FILED WILL
ONLY BE ALLOWED TO THE EXTENT THE FINAL TREASURY REGULATIONS PERMIT
SUCH A PROTECTIVE ELECTION. 3.3 OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEES SOLE RESPONSIBILITY,
AND NOT THE CORPORATIONS, TO FILE A TIMELY ELECTION UNDER SECTION 83(B), EVEN
IF OPTIONEE REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING
ON HIS/HER BEHALF. This filing should be made by registered or certified mail,
return receipt requested, and Optionee must retain two (2) copies of the
completed form for filing with his or her Federal and state tax returns for the
current tax year and an additional copy for his or her records. IV. TRANSFER RESTRICTIONS 4.1 RESTRICTION ON TRANSFER. Optionee shall not transfer, assign,
encumber or otherwise dispose of any of the Purchased Shares which are subject
to the Corporations Repurchase Right under Article V. In addition, Purchased
Shares which are released from the Repurchase Right shall not be transferred,
assigned, encumbered or otherwise made the subject of disposition in
contravention of the Corporations First Refusal Right under Article VI. Such
restrictions on transfer, however, shall NOT be applicable to (i) a gratuitous
transfer of the Purchased Shares, PROVIDED AND ONLY IF the Optionee obtains the
Corporations prior written consent to such transfer, (ii) a transfer of title
to the Purchased Shares effected pursuant to the Optionees will or the laws of
intestate succession or (iii) a transfer to the Corporation in pledge as
security for any purchase-money indebtedness incurred by the Optionee in
connection with the acquisition of the Purchased Shares. 4.2 TRANSFEREE OBLIGATIONS. Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of one of the permitted
transfers specified in paragraph 4.1 must, as a condition precedent to the
validity of such transfer, acknowledge in writing to the Corporation that such
person is bound by the provisions of this Agreement and that the transferred
shares are subject to (i) both the Corporations Repurchase Right and the
Corporations First Refusal Right granted hereunder and (ii) the market stand-
off provisions of paragraph 4.4, to the same extent such shares would be so
subject if retained by the Optionee. 4.3 DEFINITION OF OWNER. For purposes of Articles IV, V, VI and VII
of this Agreement, the term Owner shall include the Optionee and all
subsequent holders of the Purchased Shares who derive their chain of ownership
through a permitted transfer from the Optionee in accordance with paragraph 4.1. 6.

##### 



4.4 MARKET STAND-OFF PROVISIONS. A. In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporations initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters. Such limitations shall be in effect for such
period of time from and after the effective date of such registration statement
as may be requested by the Corporation or such underwriters; PROVIDED, however,
that in no event shall such period exceed one hundred-eighty (180) days. The
limitations of this paragraph 4.4 shall remain in effect for the two-year period
immediately following the effective date of the Corporations initial public
offering and shall thereafter terminate and cease to have any force or effect. B. Owner shall be subject to the market stand-off provisions of this
paragraph 4.4 PROVIDED AND ONLY IF the officers and directors of the Corporation
are also subject to similar arrangements. C. In the event of any stock dividend, stock split, recapitalization
or other change affecting the Corporations outstanding Common Stock effected as
a class without receipt of consideration, then any new, substituted or
additional securities distributed with respect to the Purchased Shares shall be
immediately subject to the provisions of this paragraph 4.4, to the same extent
the Purchased Shares are at such time covered by such provisions. D. In order to enforce the limitations of this paragraph 4.4, the
Corporation may impose stop-transfer instructions with respect to the Purchased
Shares until the end of the applicable stand-off period. V. REPURCHASE RIGHT 5.1 GRANT. The Corporation is hereby granted the right (the
Repurchase Right), exercisable at any time during the sixty (60)-day period
following the date the Optionee ceases for any reason to remain in Service or
(if later) during the sixty (60)-day period following the execution date of this
Agreement, to repurchase at the Option Price all or (at the discretion of the
Corporation and with the consent of the Optionee) any portion of the Purchased
Shares in which the Optionee has not acquired a vested interest in accordance
with the vesting provisions of paragraph 5.3 (such shares to be hereinafter
called the Unvested Shares). For purposes of this Agreement, the Optionee
shall be deemed to remain in Service for so long as the Optionee continues to
render periodic services to the Corporation or any parent or subsidiary
corporation, whether as an employee, a non-employee member of the board of
directors, or a consultant. 7.

##### 



5.2 EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be
exercisable by written notice delivered to the Owner of the Unvested Shares
prior to the expiration of the applicable sixty (60)-day period specified in
paragraph 5.1. The notice shall indicate the number of Unvested Shares to be
repurchased and the date on which the repurchase is to be effected, such date to
be not more than thirty (30) days after the date of notice. To the extent one
or more certificates representing Unvested Shares may have been previously
delivered out of escrow to the Owner, then Owner shall, prior to the close of
business on the date specified for the repurchase, deliver to the Secretary of
the Corporation the certificates representing the Unvested Shares to be
repurchased, each certificate to be properly endorsed for transfer. The
Corporation shall, concurrently with the receipt of such stock certificates
(either from escrow in accordance with paragraph 7.3 or from Owner as herein
provided), pay to Owner in cash or cash equivalents (including the cancellation
of any purchase-money indebtedness), an amount equal to the Option Price
previously paid for the Unvested Shares which are to be repurchased. 5.3 TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under paragraph 5.2. In addition, the Repurchase Right shall
terminate, and cease to be exercisable, with respect to any and all Purchased
Shares in which the Optionee vests in accordance with the vesting schedule
specified in the Grant Notice. All Purchased Shares as to which the Repurchase
Right lapses shall, however, continue to be subject to (i) the First Refusal
Right of the Corporation and its assignees under Article VI, (ii) the market
stand-off provisions of paragraph 4.4 and (iii) the Special Purchase Right under
Article VIII. 5.4 AGGREGATE VESTING LIMITATION. If the Option is exercised in more
than one increment so that the Optionee is a party to one or more other Stock
Purchase Agreements (Prior Purchase Agreements) which are executed prior to
the date of this Agreement, then the total number of Purchased Shares as to
which the Optionee shall be deemed to have a fully-vested interest under this
Agreement and all Prior Purchase Agreements shall not exceed in the aggregate
the number of Purchased Shares in which the Optionee would otherwise at the time
be vested, in accordance with the vesting provisions of paragraph 5.3, had all
the Purchased Shares been acquired exclusively under this Agreement. 5.5 FRACTIONAL SHARES. No fractional shares shall be repurchased by
the Corporation. Accordingly, should the Repurchase Right extend to a
fractional share (in accordance with the vesting provisions of paragraph 5.3) at
the time the Optionee ceases Service, then such fractional share shall be added
to any fractional share in which the Optionee is at such time vested in order to
make one whole vested share no longer subject to the Repurchase Right. 5.6 ADDITIONAL SHARES OR SUBSTITUTED SECURITIES. In the event of any
stock dividend, stock split, recapitalization or other change affecting the
Corporations outstanding Common Stock as a class effected without receipt of
consideration, then any new, 8.

##### 



substituted or additional securities or other property (including money paid
other than as a regular cash dividend) which is by reason of any such
transaction distributed with respect to the Purchased Shares shall be
immediately subject to the Repurchase Right, but only to the extent the
Purchased Shares are at the time covered by such right. Appropriate adjustments
to reflect the distribution of such securities or property shall be made to the
number of Purchased Shares and Total Purchasable Shares hereunder and to the
price per share to be paid upon the exercise of the Repurchase Right in order to
reflect the effect of any such transaction upon the Corporations capital
structure; PROVIDED, however, that the aggregate purchase price shall remain the
same. 5.7 CORPORATE TRANSACTION. A. Immediately prior to the consummation of any of the following
shareholder-approved transactions (a Corporate Transaction): (i) a merger or consolidation in which the Corporation is not
the surviving entity, except for a transaction the principal purpose of
which is to change the State of the Corporations incorporation, or (ii) the sale, transfer or other disposition of all or
substantially all of the assets of the Corporation in complete liquidation
or dissolution of the Corporation; or (iii) any reverse merger in which the Corporation is the surviving
entity but in which all of the Corporations outstanding voting stock is
transferred to the acquiring entity or its wholly-owned subsidiary, the Repurchase Right shall automatically lapse in its entirety except to the
extent the Repurchase Right is to be assigned to the successor corporation (or
its parent company) in connection with such Corporate Transaction. B. To the extent the Repurchase Right remains in effect following
such Corporate Transaction, such right shall apply to the new capital stock or
other property (including cash) received in exchange for the Purchased Shares in
consummation of the Corporate Transaction, but only to the extent the Purchased
Shares are at the time covered by such right. Appropriate adjustments shall be
made to the price per share payable upon exercise of the Repurchase Right to
reflect the effect of the Corporate Transaction upon the Corporations capital
structure; PROVIDED, however, that the aggregate purchase price shall remain the
same. VI. RIGHT OF FIRST REFUSAL 6.1 GRANT. The Corporation is hereby granted the right of first
refusal (the First Refusal Right), exercisable in connection with any proposed
transfer of the Purchased 9.




---



##### 



Shares in which the Optionee has vested in accordance with the vesting
provisions of Article V. For purposes of this Article VI, the term transfer
shall include any sale, assignment, pledge, encumbrance or other disposition for
value of the Purchased Shares intended to be made by the Owner, but shall not
include any of the permitted transfers under paragraph 4.1. 6.2 NOTICE OF INTENDED DISPOSITION. In the event the Owner desires
to accept a bona fide third-party offer for the transfer of any or all of the
Purchased Shares (the shares subject to such offer to be hereinafter called the
Target Shares), Owner shall promptly (i) deliver to the Corporate Secretary of
the Corporation written notice (the Disposition Notice) of the terms and
conditions of the offer, including the purchase price and the identity of the
third-party offeror, and (ii) provide satisfactory proof that the disposition of
the Target Shares to such third-party offeror would not be in contravention of
the provisions set forth in Articles II and IV of this Agreement. 6.3 EXERCISE OF RIGHT. The Corporation (or its assignees) shall, for
a period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares specified in the
Disposition Notice upon the same terms and conditions specified therein or upon
terms and conditions which do not materially vary from those specified therein.
Such right shall be exercisable by delivery of written notice (the Exercise
Notice) to Owner prior to the expiration of the twenty-five (25)-day exercise
period. If such right is exercised with respect to all the Target Shares
specified in the Disposition Notice, then the Corporation (or its assignees)
shall effect the repurchase of the Target Shares, including payment of the
purchase price, not more than five (5) business days after delivery of the
Exercise Notice; and at such time Owner shall deliver to the Corporation the
certificates representing the Target Shares to be repurchased, each certificate
to be properly endorsed for transfer. To the extent any of the Target Shares
are at the time held in escrow under Article VII, the certificates for such
shares shall automatically be released from escrow and delivered to the
Corporation for purchase. Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation (or its assignees) shall have the right to pay the purchase price in
the form of cash equal in amount to the value of such property. If the Owner
and the Corporation (or its assignees) cannot agree on such cash value within
ten (10) days after the Corporations receipt of the Disposition Notice, the
valuation shall be made by an appraiser of recognized standing selected by the
Owner and the Corporation (or its assignees) or, if they cannot agree on an
appraiser within twenty (20) days after the Corporations receipt of the
Disposition Notice, each shall select an appraiser of recognized standing and
the two appraisers shall designate a third appraiser of recognized standing,
whose appraisal shall be determinative of such value. The cost of such
appraisal shall be shared equally by the Owner and the Corporation. The closing
shall then be held on the LATER of (i) the fifth business day following delivery
of the Exercise Notice or (ii) the fifth business day after such cash valuation
shall have been made. 10.




---



##### 



6.4 NON-EXERCISE OF RIGHT. In the event the Exercise Notice is not
given to Owner within twenty-five (25) days following the date of the
Corporations receipt of the Disposition Notice, Owner shall have a period of
thirty (30) days thereafter in which to sell or otherwise dispose of the Target
Shares to the third-party offeror identified in the Disposition Notice upon
terms and conditions (including the purchase price) no more favorable to such
third-party offeror than those specified in the Disposition Notice; PROVIDED,
however, that any such sale or disposition must not be effected in contravention
of the provisions of Article II of this Agreement. To the extent any of the
Target Shares are at the time held in escrow under Article VII, the certificates
for such shares shall automatically be released from escrow and surrendered to
the Owner. The third-party offeror shall acquire the Target Shares free and
clear of the Corporations Repurchase Right under Article V and the
Corporations First Refusal Right hereunder, but the acquired shares shall
remain subject to (i) the securities law restrictions of paragraph 2.2(a) and
(ii) the market stand-off provisions of paragraph 4.4. In the event Owner does
not effect such sale or disposition of the Target Shares within the specified
thirty (30)-day period, the Corporations First Refusal Right shall continue to
be applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses in accordance with paragraph 6.7. 6.5 PARTIAL EXERCISE OF RIGHT. In the event the Corporation (or its
assignees) makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within thirty (30) days after the date of the Disposition Notice, to
effect the sale of the Target Shares pursuant to one of the following
alternatives: (i) sale or other disposition of all the Target Shares to the
third-party offeror identified in the Disposition Notice, but in full
compliance with the requirements of paragraph 6.4, as if the Corporation
did not exercise the First Refusal Right hereunder; or (ii) sale to the Corporation (or its assignees) of the portion of
the Target Shares which the Corporation (or its assignees) has elected to
purchase, such sale to be effected in substantial conformity with the
provisions of paragraph 6.3. Failure of Owner to deliver timely notification to the Corporation
under this paragraph 6.5 shall be deemed to be an election by Owner to sell the
Target Shares pursuant to alternative (i) above. 6.6 RECAPITALIZATION/MERGER (a) In the event of any stock dividend, stock split, recapitalization
or other transaction affecting the Corporations outstanding Common Stock as a
class effected without receipt of consideration, then any new, substituted or
additional securities or other 11.

##### 



property which is by reason of such transaction distributed with respect to the
Purchased Shares shall be immediately subject to the Corporations First Refusal
Right hereunder, but only to the extent the Purchased Shares are at the time
covered by such right. (b) In the event of either of the following shareholder-approved
transactions: (i) a merger or consolidation in which the Corporation is
not the surviving entity, or (ii) any reverse merger in which the Corporation is the
surviving entity but in which all of the Corporations outstanding voting
stock is transferred to the acquiring entity or its wholly-owned
subsidiary, the Corporations First Refusal Right shall remain in full force and
effect and shall apply to the new capital stock or other property received in
exchange for the Purchased Shares in consummation of the transaction, but only
to the extent the Purchased Shares are at the time covered by such right. 6.7 LAPSE. The First Refusal Right under this Article VI shall lapse
and cease to have effect upon the EARLIEST to occur of (i) the first date on
which shares of the Corporations Common Stock are held of record by more than
five hundred (500) persons, (ii) a determination is made by the Corporations
Board of Directors that a public market exists for the outstanding shares of the
Corporations Common Stock or (iii) a firm commitment underwritten public
offering, pursuant to an effective registration statement under the 1933 Act,
covering the offer and sale of the Corporations Common Stock in the aggregate
amount of at least $5,000,000. However, the market stand-off provisions of
paragraph 4.4 shall continue to remain in full force and effect following the
lapse of the First Refusal Right hereunder. VII. ESCROW 7.1 DEPOSIT. Upon issuance, the certificates for any Unvested Shares
purchased hereunder shall be deposited in escrow with the Corporate Secretary of
the Corporation to be held in accordance with the provisions of this Article
VII. Each deposited certificate shall be accompanied by a duly-executed
Assignment Separate from Certificate in the form of Exhibit I. The deposited
certificates, together with any other assets or securities from time to time
deposited with the Corporate Secretary pursuant to the requirements of this
Agreement, shall remain in escrow until such time or times as the certificates
(or other assets and securities) are to be released or otherwise surrendered for
cancellation in accordance with paragraph 7.3. Upon delivery of the
certificates (or other assets and securities) to the Corporate Secretary of the
Corporation, the Owner shall be issued an instrument of deposit acknowledging
the number of Unvested Shares (or other assets and securities) delivered in
escrow. 12

##### 



7.2 RECAPITALIZATION. All regular cash dividends on the Unvested
Shares (or other securities at the time held in escrow) shall be paid directly
to the Owner and shall not be held in escrow. However, in the event of any
stock dividend, stock split, recapitalization or other change affecting the
Corporations outstanding Common Stock as a class effected without receipt of
consideration or in the event of a Corporate Transaction, any new, substituted
or additional securities or other property which is by reason of such
transaction distributed with respect to the Unvested Shares shall be immediately
delivered to the Corporate Secretary to be held in escrow under this Article
VII, but only to the extent the Unvested Shares are at the time subject to the
escrow requirements of paragraph 7.1. 7.3 RELEASE/SURRENDER. The Unvested Shares, together with any other

Repurchase Right in accordance with the applicable provisions of

other marital property rights such spouse may have in such shares. 8.2 NOTICE OF DECREE OR AGREEMENT. The Optionee shall promptly
provide the Secretary of the Corporation with written notice (the Dissolution
Notice) of (i) the entry of any judicial decree or order resolving the property
rights of the Optionee and the Optionees spouse in connection with their
marital dissolution or legal separation or (ii) the execution of any contract or
agreement relating to the distribution or division of such property rights. The
Dissolution Notice shall be accompanied by a copy of the actual decree of
dissolution or settlement agreement between the Optionee and the Optionees
spouse which provides for the award to the spouse of one or more Purchased
Shares in settlement of any community property or other marital property rights
such spouse may have in such shares. 8.3 EXERCISE OF SPECIAL PURCHASE RIGHT. The Special Purchase Right
shall be exercisable by delivery of written notice (the Purchase Notice) to
the Optionee and the Optionees spouse within thirty (30) days after the
Corporations receipt of the Dissolution Notice. The Purchase Notice shall
indicate the number of shares to be purchased by the Corporation, the date such
purchase is to be effected (such date to be not less than five (5) business
days, nor more than ten (10) business days, after the date of the Purchase
Notice), and the fair market value to be paid for such Purchased Shares. The
Optionee (or the Optionees spouse, to the extent such spouse has physical
possession of the Purchased Shares) shall, prior to the close of business on the
date specified for the purchase, deliver to the Corporate Secretary of the
Corporation the certificates representing the shares to be purchased, each
certificate to be properly endorsed for transfer. To the extent any of the
shares to be purchased by the Corporation are at the time held in escrow under
Article VII, the certificates for such shares shall be promptly delivered out of
escrow to the Corporation. The Corporation shall, concurrently with the receipt
of the stock certificates, pay to the Optionees spouse (in cash or cash
equivalents) an amount equal to the fair market value specified for such shares
in the Purchase Notice. If the Optionees spouse does not agree with the fair market value
specified for the shares in the Purchase Notice, then the spouse shall promptly
notify the Corporation in writing of such disagreement and the fair market value
of such shares shall thereupon be determined by an appraiser of recognized
standing selected by the Corporation and the spouse. If they cannot agree on an
appraiser within twenty (20) days after the date of the Purchase Notice, each
shall select an appraiser of recognized standing, and the two appraisers shall
designate a third appraiser of recognized standing whose appraisal shall be
determinative of such value. The cost of the appraisal shall be shared equally
by the Corporation and the Optionees spouse. The closing shall then be held on
the fifth business day following the completion of such appraisal; PROVIDED,
however, that if the appraised value is more than fifteen percent (15%) greater
than the fair market value specified for the shares in the Purchase Notice, the
Corporation shall have the right, exercisable prior to the 15.

Special Purchase Right and thereby revoke its election to purchase the shares
awarded to the spouse. 8.4 LAPSE. The Special Purchase Right under this Article VIII shall
lapse and cease to have effect upon the EARLIER to occur of (i) the first date
on which the First Refusal Right under Article VI lapses or (ii) the expiration
of the thirty (30)-day exercise period specified in paragraph 8.3, to the extent
the Special Purchase Right is not timely exercised in accordance with such
paragraph. IX. GENERAL PROVISIONS 9.1 ASSIGNMENT. The Corporation may assign its Repurchase Right
under Article V, its First Refusal Right under Article VI and/or its Special
Purchase Right under Article VIII to any person or entity selected by the
Corporations Board of Directors, including (without limitation) one or more
shareholders of the Corporation. If the assignee of the Repurchase Right is other than a one hundred
percent (100%) owned subsidiary corporation of the Corporation or the parent
corporation owning one hundred percent (100%) of the Corporation, then such
assignee must make a cash payment to the Corporation, upon the assignment of the
Repurchase Right, in an amount equal to the excess (if any) of (i) the fair
market value of the Unvested Shares at the time subject to the assigned
Repurchase Right over (ii) the aggregate repurchase price payable for the
Unvested Shares thereunder. 9.2 DEFINITIONS. For purposes of this Agreement, the following
provisions shall be applicable in determining the parent and subsidiary
corporations of the Corporation: (i) Any corporation (other than the Corporation) in an
unbroken chain of corporations ending with the Corporation shall be
considered to be a parent corporation of the Corporation, provided each
such corporation in the unbroken chain (other than the Corporation) owns,
at the time of the determination, stock possessing fifty percent (50%) or
more of the total combined voting power of all classes of stock in one of
the other corporations in such chain. (ii) Each corporation (other than the Corporation) in an
unbroken chain of corporations beginning with the Corporation shall be
considered to be a subsidiary of the Corporation, provided each such
corporation (other than the last corporation) in the unbroken chain owns,
at the time of the determination, stock possessing fifty percent (50%) or
more of the total combined voting power of all classes of stock in one of
the other corporations in such chain. 16.

9.3 NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or
in the Plan shall confer upon the Optionee any right to continue in the Service
of the Corporation (or any parent or subsidiary corporation of the Corporation
employing or retaining Optionee) for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any parent or subsidiary corporation of the Corporation employing or
retaining Optionee) or the Optionee, which rights are hereby expressly reserved
by each, to terminate the Optionees Service at any time for any reason
whatsoever, with or without cause. 9.4 NOTICES. Any notice required in connection with (i) the
Repurchase Right, the Special Purchase Right or the First Refusal Right or (ii)
the disposition of any Purchased Shares covered thereby shall be given in
writing and shall be deemed effective upon personal delivery or upon deposit in
the United States mail, registered or certified, postage prepaid and addressed

signature line on this Agreement or at such other address as such party may

any instance to exercise the Repurchase Right granted under Article V, or the
failure of the Corporation (or its assignees) in any instance to exercise the
First Refusal Right granted under Article VI, or the failure of the Corporation
(or its assignees) in any instance to exercise the Special Purchase Right
granted under Article VIII shall not constitute a waiver of any other repurchase
rights and/or rights of first refusal that may subsequently arise under the
provisions of this Agreement or any other agreement between the Corporation and
the Optionee or the Optionees spouse. No waiver of any breach or condition of
this Agreement shall be deemed to be a waiver of any other or subsequent breach
or condition, whether of like or different nature. 9.6 CANCELLATION OF SHARES. If the Corporation (or its assignees)
shall make available, at the time and place and in the amount and form provided
in this Agreement, the consideration for the Purchased Shares to be repurchased
in accordance with the provisions of this Agreement, then from and after such
time, the person from whom such shares are to be repurchased shall no longer
have any rights as a holder of such shares (other than the right to receive
payment of such consideration in accordance with this Agreement), and such
shares shall be deemed purchased in accordance with the applicable provisions
hereof and the Corporation (or its assignees) shall be deemed the owner and
holder of such shares, whether or not the certificates therefor have been
delivered as required by this Agreement. 17.

SPECIAL PROTECTIVE ELECTION PURSUANT TO SECTION 83(b) OF THE INTERNAL
REVENUE CODE WITH RESPECT TO PROPERTY ACQUIRED UPON EXERCISE OF AN
INCENTIVE STOCK OPTION The property described in the above Section 83(b) election is comprised of
shares of common stock acquired pursuant to the exercise of an incentive stock
option under Section 422 of the Code. Accordingly, it is the intent of the
Taxpayer to utilize this election to achieve the following tax results: 1. The purpose of this election is to have the alternative minimum
taxable income attributable to the purchased shares measured by the amount by
which the fair market value of such shares at the time of their transfer to the
Taxpayer exceeds the purchase price paid for the shares. In the absence of this
election, such alternative minimum taxable income would be measured by the
spread between the fair market value of the purchased shares and the purchase
price which exists on the various lapse dates in effect for the forfeiture
restrictions applicable to such shares. The election is to be effective to the
full extent permitted under the Internal Revenue Code. 2. Section 421(a)(1) of the Code expressly excludes from income any
excess of the fair market value of the purchased shares over the amount paid for
such shares. Accordingly, this election is also intended to be effective in the
event there is a disqualifying disposition of the shares, within the meaning
of Section 421(b) of the Code, which would otherwise render the provisions of
Section 83(a) of the Code applicable at that time. Consequently, the Taxpayer
hereby elects to have the amount of disqualifying disposition income measured by
the excess of the fair market value of the purchased shares on the date of
transfer to the Taxpayer over the amount paid for such shares. Since Section
421(a) presently applies to the shares which are the subject of this Section
83(b) election, no taxable income is actually recognized for regular tax
purposes at this time, and no income taxes are payable, by the Taxpayer as a
result of this election. This form should be filed with the Internal Revenue Service Center with which
taxpayer files his/her Federal income tax returns. The filing must be made
within 30 days after the execution date of the Stock Purchase Agreement. NOTE: THIS PAGE SHOULD BE ATTACHED ONLY IF YOU ARE EXERCISING AN INCENTIVE
STOCK OPTION.
