RESTRICTED STOCK AGREEMENT

THIS RESTRICTED STOCK AGREEMENT (this “Agreement”) is made as of this 22nd day of September, 2000, by and between Danger Research, Inc., a Delaware corporation (the “Company”), and Matthew J. Hershenson. (“Purchaser”).

WHEREAS, Purchaser has purchased 4,000,000 shares of the Company’s Common Stock (the “Shares”), at a purchase price of $0.0075 per share (the “Purchase Price”), or $30,000 in the aggregate pursuant to that certain Restricted Stock Purchase Agreement, dated March 10, 2000, by and between Purchaser and the Company (the “Grant Agreement”);

WHEREAS, the Company has entered into a Series A Preferred Stock Purchase Agreement (the “Series A Purchase Agreement”), of even date herewith, under which the Company has agreed to sell, to the investors listed on Schedule A thereto (the “Investors”), and the Investors have agreed to purchase, shares of the Series A Preferred Stock of the Company;

WHEREAS, execution and delivery of this Agreement is a condition to the obligations of the Investors under the Series A Purchase Agreement; and

WHEREAS, the purpose of this Agreement is to amend and supplement (and not to restate in its entirety) the Grant Agreement;

NOW THEREFORE, in consideration of the mutual promises and obligations set forth herein and in the Series A Purchase Agreement and the documents executed and delivered in connection therewith, the parties agree as follows:

1.1 Restricted Securities.

(a) Purchaser hereby confirms that Purchaser has been informed that the Shares are restricted securities under the Securities Act of 1933, as amended (“1933 Act”), and may not be resold or transferred unless the Shares are first registered under the federal securities laws or unless an exemption from such registration is available. Accordingly, Purchaser hereby acknowledges that Purchaser is prepared to hold the Shares for an indefinite period and that Purchaser is aware that Rule 144 of the Securities and Exchange Commission (“SEC”) issued under the 1933 Act is not presently available to exempt the sale of the 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 Company first becomes subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Shares, to the extent vested under Article IV, may be sold (without registration) pursuant to the applicable requirements of Rule 144. If Purchaser is at the time of such sale an affiliate of the Company 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 one year holding period requirement of the Rule will not be applicable. If Purchaser is not at the time of the sale an affiliate of the Company 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 Shares held for fewer than two (2) years following payment in cash of the Purchase Price therefor) will be applicable to the sale. The requirements of Rule 144 are subject to change at any time.

1.

(c) Should the Company not become subject to the reporting requirements of the Exchange Act, then Purchaser may, provided he is not at the time an affiliate of the Company (nor was such an affiliate during the preceding three (3) months), sell the Shares (without registration) pursuant to paragraph (k) of Rule 144 after the Shares have been held for a period of two (2) years following the payment in cash of the Purchase Price for such shares.

1.2 Disposition of Shares. Subject to the terms of this Agreement, Purchaser hereby agrees that Purchaser shall make no disposition of the Shares (other than a permitted transfer under paragraph 3.2) unless and until there is compliance with all of the following requirements:

(a) Purchaser shall have notified the Company of the proposed disposition and provided a written summary of the terms and conditions of the proposed disposition;

(b) Purchaser shall have complied with all requirements of this Agreement applicable to the disposition of the Shares;

(c) Purchaser shall have provided the Company with written assurances, in form and substance satisfactory to the Company, that (i) the proposed disposition does not require registration of the 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; and

(d) Purchaser shall have provided the Company with written assurances, in form and substance satisfactory to the Company, that the proposed disposition will not result in the contravention of any transfer restrictions applicable to the Shares.

The Company shall not be required (i) to transfer on its books any Shares which have been sold or transferred in violation of the provisions of this Article I nor (ii) to treat as the owner of the Shares, or otherwise to accord voting or dividend rights to, any transferee to whom the Shares have been transferred in contravention of this Agreement.

1.3 Restrictive Legends. In order to reflect the restrictions on disposition of the Shares, the stock certificates for the Shares have been endorsed with restrictive legends, including legends in substantially the form of one or more of the following legends:

(a) “The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended. The shares may not be sold or offered for sale in the absence of (1) an effective registration statement for the shares under such Act, (2) a ‘no action’ letter of the SEC with respect to such sale or offer, or (3) satisfactory assurances to the Company that registration under such Act is not required with respect to such sale or offer.”

(b) “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 between the Company 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 Company (or its assignees) upon the sale, assignment, transfer, encumbrance or other disposition of the Company’s shares or upon termination of service with the Company. The Company will upon written request furnish a copy of such agreement to the holder hereof without charge.”

2.

2.1 Valuation of Common Stock. Purchaser understands that the price paid for the Shares has been valued by the Board of Directors and that the Company believes this valuation represents a fair attempt at reaching an accurate appraisal of their worth; Purchaser understands, however, that the Company can give no assurances that such price is in fact the fair market value of the Shares and that it is possible that, with the benefit of hindsight, the Internal Revenue Service would successfully assert that the value of the Shares on the date of purchase is substantially greater than so determined.

If the Internal Revenue Service were to succeed in a tax determination that the Shares received had value greater than that upon which the transaction was based, the additional value would constitute ordinary income as of the date of its receipt. The additional taxes (and interest) due would be payable by Purchaser, and there is no provision for the Company to reimburse him for that tax liability, and Purchaser assumes all responsibility for such potential tax liability. In the event that such additional value would represent more than twenty-five percent (25%) of Purchaser’s gross income for the year in which the value of the Shares was taxable, the Internal Revenue Service would have six years from the due date for filing the return (or the actual filing date of the return if filed thereafter) within which to assess Purchaser the additional tax and interest which would then be due.

The Company would have the benefit, in any such transaction, if a determination was made prior to the three year statute of limitations period affecting the Company, of an increase in its deduction for compensation paid, which would offset its operating profits, or, if not profitable, would create net operating loss carry forward arising from operations in that year.

3.1 Definition of Owner. For purposes of this Agreement, the term “Owner” shall include the Purchaser and all subsequent holders of the Shares who derive their chain of ownership through a permitted transfer from the Purchaser in accordance with paragraph 3.2.

3.2 Restriction on Transfer. Owner shall not transfer, assign, encumber or otherwise dispose of any of the Shares which are subject to the Company’s Repurchase Rights in this Agreement. In addition, Shares which are released from the Repurchase Rights shall not be transferred, assigned, encumbered or otherwise made the subject of disposition in contravention of the Company’s First Refusal Right under Article V or as otherwise limited herein. Such restrictions on transfer, however, shall not be applicable to (i) a gratuitous transfer of the Shares made to the Owner’s spouse or issue, including adopted children, or to a trust for the exclusive benefit of the Owner or the Owner’s spouse or issue, provided and only if the Owner obtains the Company’s prior written consent to such transfer and such transferee agrees to be bound by the terms of this Agreement, (ii) a transfer of title to the Shares effected pursuant to the Owner’s will or the laws of intestate succession or (iii) a transfer to the Company in pledge as security for any purchase-money indebtedness incurred by Purchaser in connection with the acquisition of the Shares.

3.3 Transferee Obligations. Each person (other than the Company) to whom the Shares are transferred by means of one of the permitted transfers specified in paragraph 3.2 must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Agreement and that the transferred shares are subject to (i) both the Company’s Repurchase Rights and the Company’s First Refusal Right granted hereunder and (ii) the market stand-off provisions of paragraph 3.4, to the same extent such Shares would be so subject if retained by the Purchaser.

3.

3.4 Market Stand-Off Provisions.

(a) In connection with the first or second underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under the 1933 Act, 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 Shares without the prior written consent of the Company 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 Company or such underwriters; provided, however, that in no event shall such period exceed one hundred-eighty (180) days and ninety (90) days for the first secondary public offering by the Company.

(b) Owner shall be subject to the market stand-off provisions of this paragraph 3.4 provided and only if the executive officers and directors of the Company are also subject to similar arrangements.

(c) In the event of any stock dividend, stock split, recapitalization or other change affecting the Company’s outstanding Common Stock effected without receipt of consideration, then any new, substituted or additional securities distributed with respect to the Shares shall be immediately subject to the provisions of this paragraph 3.4, to the same extent the Shares are at such time covered by such provisions.

(d) In order to enforce the limitations of this paragraph 3.4, the Company may impose stop-transfer instructions with respect to the Shares until the end of the applicable stand-off period.

4.1 Grant. The Company (or its assignees) is hereby granted the right (the “Repurchase Right”), exercisable at any time during the sixty (60)-day period following the date the Purchaser ceases for any reason to remain in service to the Company (“Service”) or (if later) during the sixty (60)-day period following the execution date of this Agreement, to repurchase at the Purchase Price all or (at the discretion of the Company) any portion of the Shares in which the Purchaser has not acquired a vested interest in accordance with the vesting provisions of this Article IV (such shares to be hereinafter called the “Unvested Shares”), For purposes of this Agreement, the Purchaser shall be deemed to remain in Service for so long as the Purchaser continues to render services to the Company or parent, subsidiary or successor corporation as an employee, consultant or director. Purchaser agrees that any Shares subject to the Repurchase Right shall be held in escrow by the Company until the Shares become vested.

4.2 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 4.1. 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 Company the certificates representing the Unvested Shares to be repurchased, each certificate to be properly endorsed for transfer. The Company shall, concurrently with the receipt of such stock certificates (either from escrow in accordance 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 per Share Purchase Price previously paid for the Unvested Shares which are to be repurchased.

4.

4.3 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 4.2. In addition, the Repurchase Right as to certain Unvested Shares shall terminate, and cease to be exercisable, solely to the extent set forth below, on the earliest to occur of (i) an Acceleration Event of the Purchaser as described in Section 4.3(b) below or (ii) with respect to any and all Shares in which the Purchaser vests in accordance with the schedule set forth in Section 4.3(a) below. Accordingly, as, and provided that, the Purchaser continues in continuous Service, as defined above, or upon the occurrence of an Acceleration Event, the Purchaser shall acquire a vested interest in, and the Repurchase Right as to certain Unvested- Shares, solely to the extent set forth below, shall lapse with respect to, the Shares in accordance with the following provisions:

(a) The Purchaser shall have a vested interest in 1,000,000 shares on the date hereof. With respect to the remaining 3,000,000 Shares, the Purchaser shall acquire a vested interest in, and the Repurchase Right shall lapse in thirty-six (36) equal and continuous monthly installments for each monthly period of continuous Service after September 22, 2000, and for the thirty-six (36) months following September 22, 2000, such that Purchaser shall be fully vested in all Shares after thirty-six (36) months of continuous Service completed by the Purchaser following September 22, 2000; and

(b) So long as the Company’s Repurchase Right remains in effect, 1,000,000 (or such lesser amount of Unvested Shares remaining) of the then Unvested Shares of the Purchaser shall vest immediately and the Repurchase Right shall lapse with respect to such number of the Unvested Shares if the Purchaser is terminated by the Company, actually or constructively, without “Cause” (an “Acceleration Event”). For purposes of this Agreement, the term “Cause” shall mean any one of the following: (i) gross negligence or the repeated failure of Purchaser, following the receipt of written notice from the Board of its dissatisfaction with the Purchaser’s performance, to perform his duties and responsibilities to the reasonable satisfaction of the Board; (ii) any breach by Purchaser of his fiduciary duties to the Company or any material term. of this Agreement; or (iii) the conviction of Purchaser for a felony. For purposes of this Agreement, any act or acts or omission or omissions by Purchaser that have a material adverse effect on the Company’s operations, prospects, reputation or business shall be deemed to be a breach of his duties and responsibilities to the Company.

(c) All Shares as to which the Repurchase Right lapses shall, however, continue to be subject to (i) the First Refusal Right until the lapse of such First Refusal Right, (ii) the market stand-off provisions of paragraph 3.4 and (iii) the Special Purchase Rights set forth under Article VII.

4.4 Fractional Shares. No fractional shares shall be repurchased by the Company. Accordingly, should the Repurchase Right extend to a fractional share (in accordance with the vesting computation provisions of paragraphs 4.3 and 4.6) at the time the Purchaser ceases Service or pursuant hereto, then such fractional share shall be added to any fractional share in which the Purchaser is at such time vested in order to make one whole vested share no longer subject to the Repurchase Right.

4.5 Additional Shares or Substituted Securities. In the event of any stock dividend, stock split, recapitalization or other change affecting the Company’s outstanding Common Stock as a class effected without receipt of consideration, then any new, 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 Shares shall be immediately subject to the Repurchase Right, but only to the extent the 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 Shares at the time subject to the Repurchase Right 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 Company’s capital structure; provided, however, that the aggregate Purchase Price shall remain the same.

5.

5.1 Grant. The Company is hereby granted the right of first refusal (the “First Refusal Right”), exercisable in connection with any proposed transfer of the Shares. For purposes of this Article V, the term “transfer” shall include any sale, assignment, pledge, encumbrance or other disposition for value of the Shares intended to be made by the Owner, but shall exclude any of the permitted transfers under paragraph 3.2.

5.2 Notice of Intended Disposition. In the event the Owner desires to accept a bona fide third-party offer for any or all of the 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 Company 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 I and III of this Agreement.

5.3 Exercise of Right. The Company (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 substantially the same terms and conditions 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 Company (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 Company 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 VI, the certificates for such shares shall automatically be released from escrow and delivered to the Company for purchase.

5.4 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 Company’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 I of this Agreement. To the extent any of the Target Shares are at the time held in escrow under Article VI, the certificates for such shares shall automatically be released from escrow and surrendered to the Owner.

5.5 Partial Exercise of Right. In the event the Company (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 Company 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:

6.

(b) sale to the Company (or its assignees) of the portion of the Target Shares which the Company (or its assignees) has elected to purchase, such sale to be effected in substantial conformity with the provisions of paragraph 5.3.

Failure of Owner to deliver timely notification to the Company under this paragraph 5.5 shall be deemed to be an election by Owner to sell the Target Shares pursuant to alternative (a) above.

5.6 Recapitalization. In the event of any stock dividend, stock split, recapitalization. or other transaction affecting the Company’s outstanding Common Stock as a class effected without receipt of consideration, then any new, substituted or additional securities or other property which is by reason of such transaction distributed with respect to the Shares shall be immediately subject to the Company’s First Refusal Right hereunder, but only to the extent the Shares are at the time covered by such right.

5.7 Lapse. The First Refusal Right under this Article V shall remain in effect under all circumstances but shall lapse and cease to have effect upon the earliest to occur of (i) the first date on which shares of the Company’s Common Stock are held of record by more than five hundred (500) persons, (ii) a determination is made by the Company’s Board of Directors that a public market exists for the outstanding shares of the Company’s Common Stock, (iii) an underwritten public offering pursuant to an effective registration statement under the 1933 Act or (iv) in the event of either of the following transactions (each a “Corporate Transaction”): (x) a merger or consolidation of the Company, in which the stockholders of the Company do not control fifty percent (50%) or more of the total voting power of the surviving entity (other than a mere reincorporation merger) or (y) the sale, transfer or other disposition of all or substantially all of the Company’s assets in liquidation or dissolution of the Company. However, the market stand-off provisions of paragraph 3.4 shall continue to remain in full force and effect following the lapse of the First Refusal Right hereunder.

6.1 Deposit. The certificates for any Unvested Shares have been deposited in escrow with the Company to be held in accordance with the provisions of this Article VI. Each deposited certificate is accompanied by a duly executed Assignment Separate from Certificate in the form of Exhibit A. The deposited certificates, together with any other assets or securities from time to time deposited with the Company 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 6.3. Upon delivery of the certificates (or other assets and securities) to the Company, the Owner shall be issued an instrument of deposit acknowledging the number of Unvested Shares (or other assets and securities) delivered in escrow to the Company.

6.2 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 Company’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 Company to be held in escrow under this Article VI, but only to the extent the Unvested Shares are at the time subject to the escrow requirements of paragraph 6.1.

7.

6.3 Release/Surrender. The Unvested Shares, together with any other assets or securities held in escrow hereunder, shall be subject to the following terms and conditions relating to their release from escrow or their surrender to the Company for repurchase and cancellation:

(a) Should the Company (or its assignees) elect to exercise the Repurchase Right under Article IV with respect to any Unvested Shares, then the escrowed certificates for such Unvested Shares (together with any other assets or securities issued with respect thereto) shall be delivered to the Company, concurrently with the payment to the Owner, in cash or cash equivalent (including the cancellation of any purchase-money indebtedness), of an amount equal to the aggregate Purchase Price for such Unvested Shares, and the Owner shall cease to have any further rights or claims with respect to such Unvested Shares (or other assets or securities attributable to such Unvested Shares).

(b) Should the Company (or its assignees) elect to exercise its First Refusal Right under Article V with respect to any vested Target Shares held at the time in escrow hereunder, then the escrowed certificates for such Target Shares (together with any other assets or securities attributable thereto) shall, concurrently with the payment of the paragraph 5.3 purchase price for such Target Shares to the Owner, be surrendered to the Company, and the Owner shall cease to have any further rights or claims with respect to such Target Shares (or other assets or securities).

(c) Should the Company (or its assignees) elect not to exercise its First Refusal Right under Article V with respect to any Target Shares held at the time in escrow hereunder, then the escrowed certificates for such Target Shares (together with any other assets or securities attributable thereto) shall be surrendered to the Owner for disposition in accordance with the provisions of paragraph 5.4.

(d) As the interest of the Owner in the Unvested Shares (or any other assets or securities attributable thereto) vests in accordance with the provisions of Article IV, the certificates for such vested shares (as well as all other vested assets and securities) shall be released from escrow and delivered to the Owner in accordance with the following schedule:

(1) Upon the Purchaser’s cessation of Service, any escrowed Shares (or other assets or securities) in which the Purchaser is at the time vested shall be promptly released from escrow.

(2) Upon any earlier termination of the Company’s Repurchase Right in accordance with the applicable provisions of Article IV, the Shares (or other assets or securities) at the time held in escrow hereunder shall promptly be released to the Owner as fully-vested shares or other property.

(3) All Shares (or other assets or securities) released from escrow in accordance with the provisions of subparagraph (2) above shall nevertheless remain subject to (i) the Company’s First Refusal Right under Article V until such right lapses pursuant to paragraph 5.7 and Article II and (ii) the market stand-off provisions of paragraph 3.4 until such provisions terminate in accordance therewith.

7.1 Grant. Notwithstanding anything in this Agreement to the contrary, in connection with the dissolution of Owner’s marriage or the legal separation of Owner and Owner’s spouse, the Company shall have the right (the “Special Purchase Right”) to purchase from Purchaser’s spouse, in accordance with the provisions of this Article VII, all or any portion of the Shares which would otherwise be awarded to such spouse in settlement of any community property or other marital property rights such spouse may have in such shares.

8.

7.2 Notice of Decree or Agreement. Owner shall promptly provide the Company with written notice (the “Dissolution Notice”) of (i) the entry of any judicial decree or order resolving the property rights of Owner and Owner’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 or order of dissolution or contract or agreement between Owner and Owner’s spouse which provides for the award to the spouse of one or more Shares in settlement of any community property or other marital property rights such spouse may have in such shares.

7.3 Exercise of the Special Purchase Right. The Special Purchase Right shall be exercisable by delivery of written notice (the “Purchase Notice”) to Owner and Owner’s spouse within forty-five (45) days after the Company’s receipt of the Dissolution Notice. The Purchase Notice shall indicate the number of Shares to be purchased by the Company, the date such purchase is to be effected (such date to be not less than five (5) business days, nor more than fifteen (15) business days, after the date of the Purchase Notice) and the fair market value to be paid for such Shares. Owner (or Owner’s spouse, to the extent such spouse has physical possession of the Shares) shall, prior to the close of business on the date specified for the purchase, deliver to the Company the certificates representing the shares to be purchased. The Company shall, concurrently with the receipt of the stock certificates, pay to Owner’s spouse (in cash or cash equivalents) an amount equal to the fair market value specified for such shares in the Purchase Notice.

If Owner’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 Company 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 Company and the spouse. If they cannot agree on an appraiser within fifteen (15) days after the date of the Purchase Notice, each shall select an appraiser of recognized standing, and the two (2) 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 Company and Owner’s spouse. The closing shall then be held on the fifteenth (15th) business day following the completion of such appraisal; provided, however, that if the appraised value is more than twenty-five percent (25%) greater than the fair market value specified for the Shares in the Purchase Notice, the Company shall have the right, exercisable prior to the expiration of such fifteen (15) business-day period, to rescind the exercise of the Special Purchase Right and thereby revoke its election to purchase the Shares awarded to the spouse.

7.4 Lapse. The Special Purchase Right shall lapse upon the earlier to occur of (i) the lapse of the First Refusal Right or (ii) the expiration of the exercise period specified in this Article VII, to the extent the Special Purchase Right is not timely exercised in accordance with such paragraph.

8.1 Assignment. The Company may assign its Repurchase Right under Article IV and/or its First Refusal Right under Article V and/or its Special Purchase Rights under Article VII to any person or entity selected by the Company’s Board of Directors, including (without limitation) one or more stockholders of the Company.

If the assignee is other than a parent or subsidiary corporation of the Company, then such assignee must make a cash payment to the Company, upon the assignment of the Repurchase Right, in an

9.

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 Unvested Shares thereunder.

8.2 Definitions. For purposes of this Agreement, the following provisions shall be applicable in determining the parent and subsidiary corporations of the Company:

(a) Any corporation (other than the Company) in an unbroken chain of corporations ending with the Company shall be considered to be a parent corporation of the Company, provided each such corporation in the unbroken chain (other than the Company) 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.

(b) Each corporation (other than the Company) in an unbroken chain of corporations beginning with the Company shall be considered to be a subsidiary of the Company, 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.

8.3 No Employment or Service Contract. Nothing contained in this Agreement shall confer upon the Purchaser any right to continue in the Service of the Company (or any parent or subsidiary corporation employing or retaining Purchaser) for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any parent or subsidiary corporation employing or retaining Purchaser) or the Purchaser, which rights are hereby expressly reserved by each, to terminate the Purchaser’s Service at any time for any reason whatsoever, with or without cause.

8.4 Notices. Any notice required in connection with (i) the Repurchase Rights or the First Refusal Right or (ii) the disposition of any 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 to the party entitled to such notice at the address indicated below such party’s signature line on this Agreement or at such other address as such party may designate by ten (10) days advance written notice under this paragraph 8.4 to all other parties to this Agreement.
