(a) Vesting Schedule. Subject to all of the provisions of this Section 6 and to any applicable provisions of the Plan (including, without limitation, (x) the provisions of Sections 7.2(g), 7.2(i), 7.2(j), 11.1 and 14.3 of the Plan to the extent applicable to the Shares and (y) the acceleration provisions, if any, set forth in the Plan to the extent applicable to the Shares), the Shares shall vest as follows: (i)                      of the Shares shall vest as of the First Vesting Date, and (ii) the remainder of the Shares shall vest in              monthly installments on the first calendar day of each month following the First Vesting Date until such Shares have become vested in full. For purposes of implementing the provisions of this Section 6(a), all Shares regardless of when they become subject to the Option or when purchased by the Optionee upon exercise of the Option shall be deemed to have become subject to the Option and purchased by the Optionee on the Grant Date as if the Optionee had exercised the Option for all of the Shares on the Grant Date.

(b) No Further Vesting Following Termination.

(c) Delivery of Vested Shares. Vested Shares that are issued and outstanding shall, at the request of the Optionee, be released from the escrow provided for in Section 8 hereof and shall be delivered to the Optionee.

(d) Escrow of Unvested Shares. All Unvested Shares that are issued and outstanding shall be held in escrow pursuant to Section 8 below.

7. Repurchase Right. In the event of a Termination for any reason or for no reason, regardless of whether such Termination is effected by voluntary resignation by the Optionee, by

the Company, by virtue of the Optionee’s death, or otherwise, the Company shall have the right, but not the obligation, to repurchase all or any number of the then Unvested Shares that are issued and outstanding and owned or held by the Optionee, subject to and in accordance with the terms of this Section 7. The Company may exercise such repurchase right by delivering to the Optionee, within thirty (30) days following the effective date of such Termination, a notice (the “Notice”) of the Company’s intention to exercise its repurchase right under this Section 7, specifying the number of such Unvested Shares that the Company desires to repurchase, whereupon, subject to the provisions of this Section 7, the Company shall become legally obligated to repurchase from the Optionee, and the Optionee shall become legally obligated to sell to the Company, at the Closing (as such term is defined below), the number of Unvested Shares referred to in the Notice, and the Company shall not be required after delivery of the Notice to treat the Optionee as owner of the Unvested Shares referred to in the Notice, to accord the right to vote to the Optionee with respect thereto or to pay dividends thereon. The purchase price per share for all of the Unvested Shares repurchased by the Company pursuant to this Section 7 shall be the purchase price originally paid by the Optionee to the Company for each of such Unvested Shares (subject to adjustment pursuant to Section 11 hereof), payable, at the election of the Company, in cash or through the cancellation of indebtedness. The closing (the “Closing’’) of the repurchase by the Company of all or any number of Unvested Shares pursuant to this Section 7 shall take place at the offices of the Company at such time and on such date as the Company shall specify in the Notice, but in no event later than sixty (60) days after the date of termination. At the Closing, the Optionee shall deliver, or cause to be delivered, to the Company a certificate or certificates evidencing the number of Unvested Shares to be repurchased, duly endorsed for transfer or accompanied by duly executed stock powers, against payment by the Company of the purchase price therefor in accordance with the terms of this Section 7. In the event that the Company has a right to repurchase any Unvested Shares pursuant to this Section 7 and elects not to, or fails to, repurchase all or a portion of such Unvested Shares in accordance with the provisions of this Section 7, all of such Unvested Shares not so repurchased shall, thereafter, be treated as Vested Shares for all purposes of this Agreement.

8. Escrow of Unvested Shares.

(a) Escrow Holder. Each stock certificate representing issued and outstanding Unvested Shares shall be held in escrow by the Escrow Holder, together with a stock assignment executed in blank by the Optionee with respect to the Unvested Shares represented by such stock certificate. Each stock certificate representing Unvested Shares shall be held in escrow pursuant to this Section 8 until all of such Unvested Shares become fully vested pursuant to, and in accordance with, the provisions of Section 6 or Section 7 hereof or until all of such Unvested Shares are repurchased by the Company pursuant to, and in accordance with, the provisions of Section 7 hereof, whichever occurs earlier.

(b) Rights of Optionee with respect to Unvested Shares held in Escrow. Subject to the terms hereof and the terms of any other agreements to which the Optionee is a party, the Optionee shall have all the rights of a stockholder with respect to all Unvested Shares that are issued and outstanding while they are held in escrow, including without limitation, the right to vote such Unvested Shares and receive any cash dividends declared thereon. If there is (i) any stock dividend, stock split or other change in such Unvested Shares, or (ii) any merger or sale of all or substantially all of the assets or other acquisition of the Company, any and all new,

substituted or additional securities to which the Optionee is entitled by reason of his/her ownership of such Unvested Shares shall be immediately subject to this escrow, deposited with the Escrow Holder and included thereafter as “Unvested Shares” for purposes of this Agreement.

The Escrow Holder shall be obligated only for the performance of such duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by him to be genuine and to have been signed or presented by the proper party or parties. The Escrow Holder shall not be personally liable for any act he may do or refrain from doing hereunder as Escrow Holder or as attorney-in-fact for the Optionee, provided that the Escrow Holder acts or refrains from acting in good faith and in the exercise of his own good judgment, and any act that he does or refrains from doing pursuant to the advice of his own attorneys, who may be counsel to the Company, shall be conclusive evidence of such good faith.

(d) Duties of the Escrow Holder.

(i) In the event of any repurchase of Unvested Shares pursuant to, and in accordance with, the provisions of Section 7 hereof, the Escrow Holder shall take all steps necessary to consummate such repurchase, including, but not limited to, presentment of stock certificates representing the Unvested Shares subject to such repurchase, together with stock powers executed by or in the name of the Optionee appropriately completed by the Escrow Holder, to the Company or its transfer agent with irrevocable instructions to register the transfer of such Unvested Shares into the name of the Company or its designee. The Optionee hereby appoints the Escrow Holder his irrevocable attorney-in-fact to execute in his name, acknowledge and deliver all stock powers and other instruments as may be necessary or desirable with respect to the repurchase of any Unvested Shares pursuant to, and in accordance with, the provisions of Section 7 hereof.

(ii) Upon the vesting of any Unvested Shares that are issued and outstanding, the Escrow Holder shall, at the request of the Optionee, either (i) promptly deliver to the Optionee the certificate or certificates representing such Unvested Shares that have become vested or (ii) promptly cause a new certificate endorsed with the appropriate legends to be issued for such Unvested Shares that have become vested and shall deliver such certificate to the Optionee.

(iii) The Escrow Holder may, but need not, submit a memorandum to the Optionee and to the Company setting forth action the Escrow Holder intends to take with respect to the escrow of any Unvested Shares and requesting the parties to acknowledge the propriety of the intended action. If, in any such case, either party fails or refuses to acknowledge the propriety of the intended action, the Escrow Holder may seek the advice of counsel, who may be counsel to the Company, and any action taken in accordance with the written advice of such counsel shall be full protection to the Escrow Holder in respect thereto against any person. It is agreed that in any event the Escrow Holder shall not be liable for any action or failure to act taken in good faith, and that his liability shall be limited to actions or inaction constituting gross negligence or willful misconduct.

(iv) It is understood and agreed that should any dispute arise with respect to the delivery, ownership or right of possession of any of the Unvested Shares held in escrow by the Escrow Holder hereunder, he is authorized and directed to retain in his possession without liability to anyone all or any part of said Unvested Shares until such dispute shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction after the time for appeal has expired and no appeal has been perfected, but he shall be under no duty whatsoever to institute or defend any such proceedings.

(v) The Escrow Holder is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case the Escrow Holder obeys or complies with any such order, judgment or decree, he shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(vi) The parties hereto understand that the Escrow Holder is legal counsel to the Company, and that said counsel may continue to act as such in the event of any dispute in connection with this Agreement or any other transaction contemplated herein or affected hereby.

(vii) By signing this Agreement, the Escrow Holder becomes a party to this Agreement only for the purposes of this Section 8.

(e) Change of Duties. The Escrow Holder’s duties hereunder may be altered, amended, modified, or revoked only by a writing signed by all of the parties hereto; provided, however, that the Company may at any time, at its option, elect to terminate this escrow by notice to the Optionee and the Escrow Holder.

(f) Costs and Fees. All reasonable costs, fees and disbursements incurred by the Escrow Holder in connection with the performance of his duties hereunder shall be borne by the Company.

A COPY OF SUCH NONSTATUTORY STOCK OPTION AND REVERSE VESTING AGREEMENT WILL BE FURNISHED TO ANY INTERESTED PARTY UPON WRITTEN REQUEST.”

(d) Transfers in Violation of this Agreement. The Company shall not be required to transfer any of the Unvested Shares on its books which shall purportedly have been transferred.

(e) Additional Restrictions on Transfer. The Optionee hereby acknowledges that any issued and outstanding Unvested Shares that become vested pursuant to, and in accordance with, the provisions of Section 6 or Section 7 hereof, and any and all beneficial interest in such Vested Shares, shall continue to be subject to any restrictions on transfer set forth in any other agreement entered into by Optionee and the Company or set forth in the Plan.

10. Compliance with Securities Laws.

(a) Pursuant to Section 8 of the Plan, it shall be a condition to the Optionee’s right to exercise the Option and purchase any Option Shares that the Company may, in its discretion, require (x) that either (i) a registration statement under the Securities Act of 1933, as amended (the “Act”), with respect to the Option Shares proposed to be purchased shall be in effect, or (ii) in the opinion of counsel for the Company, the proposed purchase shall be exempt from registration under that Act and the Optionee shall have made such undertakings and agreements with the Company as the Company may reasonably require, and (y) that such other steps, if any, as counsel for the Company shall consider necessary to comply with any law applicable to the issue of such shares by the Company shall have been taken by the Company or the Optionee, or both.

(b) The Optionee represents and warrants that any Shares acquired by him/her or that may be acquired by him/her are being or will be, as the case may be, acquired for his/her own account for the purpose of investment and not with a view to the resale or distribution thereof.

(c) The parties agree that none of the Shares or any beneficial interest therein shall be sold, transferred, assigned, pledged, encumbered or otherwise disposed of in any way (including, without limitation, by operation of law) unless and until (i) such Shares or such

beneficial interest, as the case may be, proposed to be sold, transferred, assigned, pledged, encumbered or otherwise disposed of are registered pursuant to an effective registration filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “Act”), or (ii) if required by the Company, the Company shall have received an opinion, in form and substance satisfactory to the Company, from the Company ·s legal counsel to the effect that the sale, transfer, assignment, pledge, encumbrance or other disposition of such Shares or such beneficial interest, as the case may be, does not require registration under the Act or any applicable state securities laws.

(d) In addition to any other legends that the Company may deem appropriate, stock certificates representing any issued and outstanding Shares shall be endorsed with a legend substantially as follows:

“THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. NO TRANSFER, SALE OR OTHER DISPOSITION OF THESE SHARES MAY BE MADE UNLESS A REGISTRATION STATEMENT WITH RESPECT TO THESE SHARES HAS BECOME EFFECTIVE UNDER SAID ACT, OR, IF REQUESTED BY THE CORPORATION, THE CORPORATION HAS BEEN FURNISHED WITH AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.”

(e) Optionee understands and agrees that neither the Company nor any agent of the Company shall be under any obligation to recognize any transfer of any of the Shares if, in the opinion of counsel for the Company, such transfer would result in violation by the Company of any federal or state law with respect to the offering, issuance or sale of securities.

11. Certain Adjustments. All references in this Agreement to the number and kind of issued and outstanding Shares and to the purchase price for any issued and outstanding Shares shall be appropriately adjusted to reflect any stock split, stock dividend, reverse stock split, reclassification, recapitalization or other change which may be made by the Company after the date of this Agreement. In the event that any such stock split, stock dividend, reverse stock split, reclassification, recapitalization or other change would cause an adjustment in the number of issued and outstanding Shares that would otherwise result in fractional shares, then such fractional shares shall be disregarded by rounding down to the nearest whole number of issued and outstanding Shares. Without limiting the generality of the foregoing, the purchase price with respect to any Shares shall never be reduced to a value below any applicable par value of such Shares.

12. Tax Consequences.

(a) Withholding Taxes. It is understood by the parties hereto that the issuance and/or sale of any of the Shares to the Optionee may be deemed compensatory in purpose and in effect and that, as a result, the Optionee may be obligated to pay withholding taxes in respect of such Shares at the time Optionee becomes subject to Federal income taxation with respect to the

receipt of such Shares. In the event that such withholding tax obligations arise, the parties hereby agree that the Company shall have no obligation to pay such withholding taxes, that payment of such withholding taxes shall be the exclusive obligation of the Optionee and that, to the extent required under applicable tax laws, the Optionee shall remit such withholding taxes to the Company for purposes of having the Company remit such withholding taxes to the applicable tax authorities. The Optionee agrees on his/her behalf, and on behalf of his/her successors and assigns, to indemnify the Company with respect to any withholding tax payment that the Company is required to make that arises from the issuance and/or sale of any of the Shares to the Optionee.

(b) Section 83(b) Election. Optionee hereby agrees to deliver to the Company a signed copy of any instrument, letter or other document he/she may execute and file with the Internal Revenue Service evidencing his/her election under Section 83(b) of the Code.
