The Award shall terminate upon the first to occur of (a) the final settlement of all Vested Units in accordance with Section 5 (including a final settlement upon the termination or cessation of Grantee’s Services) or (b) the Expiration Date if settlement has not occurred on or before the Expiration Date.

3. Vesting of Units .

3.1 Satisfaction of Service Condition. Except as provided by Section 3.3 below and subject to the Grantee’s continuous Service through the applicable date set forth in the table below (each a, “ Service Date ”), the Service Condition will be satisfied, and the Units will vest, in accordance with the following schedule:

3.2 Vesting Upon Change in Control or Upon Termination Without Cause or Due to Death, Complete Disability or Good Reason. If a Change in Control occurs prior to the Expiration Date, and prior to the termination of Grantee’s Service as Chairman of the Board, then the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units that are subject to vesting effective as of the date of such Change in Control. If the Grantee’s Service as Chairman of the Board is involuntarily terminated by the Company for any reason other than Cause or the Grantee’s Service terminates as a result of the Grantee’s death or Complete Disability or Grantee terminates his Service as Chairman for Good Reason prior to the Expiration Date and Grantee executes a release in accordance with the Chairman Agreement, then the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units that are subject to vesting effective as of the date of such termination of Service.

3.3 Effect of Termination of Service. Subject to the vesting provisions in Sections 3.1, and 3.2 above, upon the termination of Grantee’s Service (whether by the Company or by Grantee and whether for Cause or for any or no reason), then:

(a) all Units for which the Service Condition has not been satisfied as of the date of such termination of Service shall be subject to the Company Reacquisition Right (as defined in Section 4.1) immediately upon the termination of Grantee’s Service; and

(b) all Units for which the Service Condition has been satisfied as of the date of such termination of Service (including as a result of Section 3.3) shall not be subject to the Company Reacquisition Right, but instead shall remain Vested Units.

3.4 Payments Upon Vesting. Upon the vesting of any Units pursuant to Sections 3.1, or 3.2, above, the Company shall, if Grantee is an employee at the time of Vesting, pay, on behalf of Grantee, the Federal Insurance Contributions Act tax imposed pursuant to Sections 3101 and 3121(v)(2) of the Code on the Vested Units (the “ FICA Amount ”). In addition, if Grantee is an employee at the time of Vesting, the Company shall pay Grantee a tax gross-up payment (computed at the highest applicable marginal rate) in an amount that, after payment of all federal, state, and local income and employment taxes, results in the Grantee’s receipt and retention, on an after-tax basis, of an amount equal to all federal, state, and local taxes payable by Grantee on the FICA Amount.

3.5 Federal Excise Tax Under Section 4999 of the Code. For avoidance of doubt, Section 6 of the Chairman Agreement is incorporated herein.

4. Company Reacquisition Right .

4.1 Grant of Company Reacquisition Right. In the event that the Grantee’s Service terminates for any reason, the Grantee shall forfeit and the Company shall automatically reacquire all Units for which the applicable Service Condition has not been satisfied as of the time of such termination in accordance with Section 3 (the “ Unvested Units ” ), and the Grantee shall not be entitled to any payment therefor (the “Company Reacquisition Right” ).

4.2 Dividends, Distributions and Adjustments . Upon the occurrence of a dividend or distribution to the stockholders of the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital structure of the Company as described in Section 7, any and all new, substituted or additional securities or other property to which the Grantee is entitled by reason of the Grantee’s ownership of Unvested Units shall be immediately subject to the Company Reacquisition Right and included in the terms “Units” and “Unvested Units” for all purposes of the Company Reacquisition Right with the same force and effect as the Unvested Units immediately prior to the dividend, distribution or adjustment, as the case may be. For purposes of determining the number of Units for which the applicable Service Condition has been satisfied following a dividend, distribution or adjustment, credited Service shall include all Service with any corporation which is a Participating Company at the time the Service is rendered, whether or not such corporation is a Participating Company both before and after any such event.

5. Settlement of the Units .

5.1 Issuance of Shares of Stock . Subject to the provisions of Section 5.3 below, the Company shall issue to the Grantee on the Settlement Date with respect to each Vested Unit to be settled on such date one (1) share of Stock.

5.2 Beneficial Ownership of Shares . A certificate for the shares acquired by the Grantee shall be registered in the name of the Grantee, or, if applicable, in the names of the heirs of the Grantee.

5.3 Transfer of Shares. The Grantee may not transfer the shares of Stock issued upon settlement of the Units except in compliance with applicable federal and state securities laws and the Company’s insider trading policy.

5.4 Fractional Shares. The Company shall not be required to issue fractional shares upon the settlement of the Units.

6. Tax Withholding .

The Grantee agrees to make adequate provision for the payment of any sums required to satisfy federal, state, local and foreign (including any social insurance) withholding obligations of the Participating Company, if any, which arise in connection with the grant or vesting of the Units or the issuance of shares of Stock in settlement thereof. The Company shall have no obligation to deliver shares of Stock until any tax withholding obligation of the Participating Company have been satisfied by the Grantee.

Grantee understands and agrees that the Grantee is currently an independent contractor and not an employee of the Company. As a result, the Company will not make deductions for taxes from any amounts payable to Grantee as a result of his Services to the Company or as a result of the vesting or settlement of the Units (except as otherwise specified in Section 3 or required by applicable law or regulation). Any taxes imposed on the Grantee due to Services to the Company (including upon the issuance, vesting and settlement of the Units) will be the sole responsibility of the Grantee (except as otherwise specified in Section 3).

7. Adjustments for Changes in Capital Structure .

Subject to any required action by the stockholders of the Company and the requirements of Section 409A of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number of Units subject to this Agreement and/or the number and kind of shares or other property to be issued in settlement of the Units, in order to prevent dilution or enlargement of the Grantee’s rights under this Agreement. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any and all new, substituted or additional securities or other property (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) to which the Grantee is entitled by reason of ownership of Units acquired pursuant to this Agreement will be immediately subject to the provisions of this Agreement on the same basis as all Units originally acquired hereunder. Any fractional Unit or share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number. Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive.

In the event of a merger or other Change in Control which does not constitute a Settlement Date, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “ Acquiror ”), shall, without the consent of the Grantee, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Units then-outstanding and this Agreement or substitute for all or any portion of the Units then-outstanding substantially equivalent restricted stock units for Acquiror’s stock. For purposes of this Section, the Units or any portion thereof shall be deemed assumed if, following the merger or Change in Control, this Agreement, as assumed, confers the right to receive, subject to the terms and conditions of this Agreement, for each Unit outstanding immediately prior to the merger or Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the merger or Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the settlement of the Units, for each share of Stock subject to the Unit, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the merger or Change in Control.

8. Rights as a Stockholder or Employee .

The Grantee shall have no rights as a stockholder with respect to any shares which may be issued in settlement of the Units until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares of Stock are issued, except as provided in Section 2.3 or Section 7. The Grantee understands and acknowledges that the Grantee’s Services to the Company is dictated by the Chairman Agreement. Nothing in this Agreement shall confer upon the Grantee any right to continue in the Service of a Participating Company or interfere in any way with any right of a Participating Company to terminate the Grantee’s Service at any time.

9. Legends .

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock issued pursuant to this Agreement. The Grantee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to this Agreement in the possession of the Grantee in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following:

An electronic Exercise Notice must be digitally signed or authenticated by the Optionee in such manner as required by the notice and transmitted to the Company or an authorized representative of the Company (including a third-party administrator designated by the Company). In the event that the Optionee is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Optionee and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company).

The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice and the aggregate Exercise Price.

4.3 Payment of Exercise Price.

(a) Forms of Consideration Authorized . Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check or in cash equivalent; (ii) if permitted by the Company and subject to the limitations contained in Section 4.3(b), by means of (1) a Cashless Exercise, (2) a Net-Exercise, or (3) a Stock Tender Exercise; or (iii) by any combination of the foregoing as approved by the Administrator.

(b) Limitations on Forms of Consideration. The Company reserves, at any and all times, the right, in its sole and absolute discretion, to establish, decline to approve or terminate any program or procedure providing for payment of the Exercise Price through any of the means described below, including with respect to the Optionee notwithstanding that such program or procedures may be available to others.

(i) Cashless Exercise. A “ Cashless Exercise ” means the delivery of a properly executed Exercise Notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to shares of Stock acquired upon the exercise of the Option in an amount not less than the aggregate Exercise Price for such shares (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System).

(ii) Net-Exercise. A “ Net-Exercise ” means the delivery of a properly executed Exercise Notice electing a procedure pursuant to which (1) the Company will reduce the number of shares otherwise issuable to the Optionee upon the exercise of the Option by the largest whole number of shares having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Optionee shall pay to the Company in cash the remaining balance of such aggregate Exercise Price not satisfied by such reduction in the number of whole shares to be issued. Following a Net-Exercise, the number of shares remaining subject to the Option, if any, shall be reduced by the sum of (1) the net number of shares issued to the Optionee upon such exercise, and (2) the number of shares deducted by the Company for payment of the aggregate Exercise Price.

(iii) Stock Tender Exercise. A “ Stock Tender Exercise ” means the delivery of a properly executed Exercise Notice accompanied by (1) the Optionee’s tender to the Company, or attestation to the ownership, in a form acceptable to the Company of whole shares of Stock having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Optionee’s payment to the Company in cash of the remaining balance of such aggregate Exercise Price not satisfied by such shares’ Fair Market Value. A Stock Tender Exercise shall not be permitted if it would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s Stock. If required by the Company, the Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for a period of time required by the Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company.

4.4 Tax Withholding .

(a) In General. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by a Participating Company, and to the extent that Optionee is an Employee, the Optionee hereby authorizes withholding from payroll and any other amounts payable to the Optionee and otherwise agrees to make adequate provision for (including by means of a Cashless Exercise to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax (including any social insurance) withholding obligations of the Participating Company Group, if any, which arise in connection with the Option. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Participating Company Group have been satisfied by the Optionee. Additionally, any taxes imposed on the Optionee due to Services to the Company (including upon the exercise of the Option) will be the sole responsibility of the Optionee (except as otherwise specified in Section 2.2).

(b) Withholding in Shares . The Company shall have the right, but not the obligation, to require the Optionee to satisfy all or any portion of a Participating Company’s tax withholding obligations upon exercise of the Option by deducting from the shares of Stock otherwise issuable to the Optionee upon such exercise a number of whole shares having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum statutory withholding rates.

4.5 Beneficial Ownership of Shares; Certificate Registration . The Optionee hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Optionee with any broker with which the Optionee has an account relationship of which the Company has notice any or all shares acquired by the Optionee pursuant to the exercise of the Option. Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, in the names of the heirs of the Optionee.

4.6 Restrictions on Grant of the Option and Issuance of Shares . The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

4.7 Fractional Shares . The Company shall not be required to issue fractional shares upon the exercise of the Option.

5. Nontransferability of the Option .

During the lifetime of the Optionee, the Option shall be exercisable only by the Optionee or the Optionee’s guardian or legal representative. The Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Optionee or the Optionee’s beneficiary, except transfer by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution.

Except as provided in the Notice of Grant or the Chairman Agreement, the Option shall terminate immediately upon the Optionee’s termination of Service to the extent that it is then unvested and shall be exercisable after the Optionee’s termination of Service to the extent it is then vested only during the applicable time period as determined below and thereafter shall terminate.

(a) Disability . Except as provided in the Notice of Grant or the Chairman Agreement, if the Optionee’s Service terminates because of the Complete Disability of the Optionee, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

(b) Death . Except as provided in the Notice of Grant or the Chairman Agreement, if the Optionee’s Service terminates because of the death of the Optionee, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the right to exercise the Option by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

(c) Termination for Cause. Except as provided in the Notice of Grant or the Chairman Agreement, notwithstanding any other provision of this Option Agreement to the contrary, if the Optionee’s Service is terminated for Cause, the Optionee may exercise those Vested Shares as of the date Optionee’s Service is terminated for Cause at any time prior to the expiration of three (3) months after the date on which the Optionee’s Service terminated for Cause, but in any event no later than the Option Expiration Date.

(d) Other Termination of Service . If the Optionee’s Service terminates for any reason not covered by Sections 3(a), 3(b) or 3(c), the Option, to the extent unexercised and exercisable for Vested Shares by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee at any time prior to the expiration of three (3) months after the date on which the Optionee’s Service terminated or such later date as determined in accordance with Section 4.2 of the Chairman Agreement, but in any event no later than the Option Expiration Date.

7.2 Extension if Exercise Prevented by Law . Notwithstanding the foregoing, other than termination of the Optionee’s Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until the later of (a) thirty (30) days after the date such exercise first would no longer be prevented by such provisions, or (b) the end of the applicable time period under Section 7.1, but in any event no later than the Option Expiration Date.

8. Effect of Change in Control .

Subject in all cases to any accelerated vesting provisions provided in the Notice of Grant or the Chairman Agreement, in the event of a merger or other Change in Control the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “ Acquiror ”), may, without the consent of the Optionee, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Option or substitute for all or any portion of the Option a substantially equivalent option for the Acquiror’s stock. For purposes of this Section, the Option or any portion thereof shall be deemed assumed if, following the merger or Change in Control, the Option confers the right to receive, subject to the terms and conditions of the Chairman Agreement and this Option Agreement, for each share of Stock subject to such portion of the Option immediately prior to the merger or Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the merger or Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Committee may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise of the Option, for each share of Stock subject to the Option, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the merger or Change in Control. The Option shall terminate and cease to be outstanding effective as of the time of consummation of the merger or Change in Control to the extent that the Option is neither assumed or continued by the Acquiror in connection with the merger or Change in Control nor exercised as of the time of the merger or Change in Control.

9. Adjustments for Changes in Capital Structure .

Subject to any required action by the stockholders of the Company and the requirements of Sections 409A of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number, Exercise Price and/or kind of shares subject to the Option, in order to prevent dilution or enlargement of the Optionee’s rights under the Option. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number and the Exercise Price shall be rounded up to the nearest whole cent. In no event may the Exercise Price be decreased to an amount less than the par value, if any, of the Stock subject to the Option. The Committee in its sole discretion, may also make such adjustments in the terms of the Option to reflect, or related to, such changes in the capital structure of the Company or distributions as it deems appropriate. All adjustments pursuant to this Section shall be determined by the Committee, and its determination shall be final, binding and conclusive.

10. Rights as a Stockholder, Director, Employee or Consultant .

The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares are issued, except as provided in Section 9. If the Optionee is an Employee, the Optionee understands and acknowledges that, except as otherwise provided in a separate, written employment agreement between a Participating Company and the Optionee, the Optionee’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Optionee any right to continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Optionee’s Service as a Director, an Employee or Consultant, as the case may be, at any time.

11. Legends .

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of Stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section.

12. Miscellaneous Provisions .

12.1 Termination or Amendment. The Committee may terminate or amend the Option at any time; provided, however, that except as provided in Section 8 in connection with a Change in Control, no such termination or amendment may have a materially adverse effect on the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is necessary to comply with any applicable law or government regulation.

2.3 Dividend Equivalent Units. On the date that the Company pays a cash dividend or other cash distribution to holders of Stock generally, the Grantee shall be credited with a number of additional whole Dividend Equivalent Units determined by dividing (a) the product of (i) the dollar amount of the cash dividend or distribution paid per share of Stock on such date and (ii) the total number of Units previously credited to the Grantee pursuant to this Agreement which have not been settled or forfeited pursuant to the Company Reacquisition Right (as defined below) as of such date, by (b) the Fair Market Value per share of Stock on such date. Any resulting fractional Dividend Equivalent Unit shall be rounded down to the nearest whole number.

Except as provided by Section 3.3 below and subject to the Grantee’s continuous Service through the applicable date set forth in the table below (each a, “ Service Date ”), the Service Condition will be satisfied, and the Units will vest, in accordance with the following schedule :

3.2 Vesting Upon Change in Control or Upon Termination Without Cause or Due to Death, Complete Disability or Good Reason.

If the Grantee’s Service is involuntarily terminated by the Company for any reason other than Cause or the Grantee’s Service terminates as a result of the Grantee’s death or Complete Disability or Grantee terminates his Service for Good Reason prior to the Expiration Date and Grantee executes a release in accordance with the Employment Agreement, then the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units that are subject to vesting effective as of the date of such termination of Service.

3.3 Effect of Termination of Service. Subject to the vesting provisions in Sections 3.1, and 3.2 above, upon the termination of Grantee’s Service (whether by the Company or by Grantee and whether for Cause or for any or no reason), then:

(a) all Units for which the Service Condition has not been satisfied as of the date of such termination of Service shall be subject to the Company Reacquisition Right (as defined in Section 4.1) immediately upon the termination of Grantee’s Service; and

(b) all Units for which the Service Condition has been satisfied as of the date of such termination of Service (including as a result of Section 3.3) shall not be subject to the Company Reacquisition Right, but instead shall remain Vested Units.

3.4 Payments Upon Vesting. Upon the vesting of any Units pursuant to Sections 3.1, or 3.2, above, the Company shall, if Grantee is an employee at the time of Vesting, pay, on behalf of Grantee, the Federal Insurance Contributions Act tax imposed pursuant to Sections 3101 and 3121(v)(2) of the Code on the Vested Units (the “ FICA Amount ”). In addition, the Company shall pay Grantee a tax gross-up payment (computed at the highest applicable marginal rate) in an amount that, after payment of all federal, state, and local income and employment taxes, results in the Grantee’s receipt and retention, on an after-tax basis, of an amount equal to all federal, state, and local taxes payable by Grantee on the FICA Amount.

3.5 Federal Excise Tax Under Section 4999 of the Code. For avoidance of doubt, Section 6 of the Employment Agreement is incorporated herein.

4. Company Reacquisition Right .

4.1 Grant of Company Reacquisition Right. In the event that the Grantee’s Service terminates for any reason, the Grantee shall forfeit and the Company shall automatically reacquire all Units for which the applicable Service Condition has not been satisfied as of the time of such termination in accordance with Section 3 (the “ Unvested Units ” ), and the Grantee shall not be entitled to any payment therefor (the “Company Reacquisition Right” ).

4.2 Dividends, Distributions and Adjustments . Upon the occurrence of a dividend or distribution to the stockholders of the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital structure of the Company as described in Section 7, any and all new, substituted or additional securities or other property to which the Grantee is entitled by reason of the Grantee’s ownership of Unvested Units shall be immediately subject to the Company Reacquisition Right and included in the terms “Units” and “Unvested Units” for all purposes of the Company Reacquisition Right with the same force and effect as the Unvested Units immediately prior to the dividend, distribution or adjustment, as the case may be. For purposes of determining the number of Units for which the applicable Service Condition has been satisfied following a dividend, distribution or adjustment, credited Service shall include all Service with any corporation which is a Participating Company at the time the Service is rendered, whether or not such corporation is a Participating Company both before and after any such event.

5. Settlement of the Units .

5.4 Fractional Shares . The Company shall not be required to issue fractional shares upon the settlement of the Units.

6. Tax Withholding .

6.1 In General. Subject to the obligations of the Participating Company under Sections 3 and 6.2 , at the time this Agreement is executed, or at any time thereafter as requested by a Participating Company, the Grantee hereby authorizes withholding from payroll and any other amounts payable to the Grantee, and otherwise agrees to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax (including any social insurance) withholding obligations of the Participating Company, if any, which arise in connection with the grant of Units, the vesting of Units or the issuance of shares of Stock in settlement thereof. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Participating Company have been satisfied by the Grantee. Additionally, any taxes imposed on the Grantee due to Services to the Company (including upon the issuance, vesting and settlement of the Units) will be the sole responsibility of the Grantee (except as otherwise specified in Section 3).

6.2 Assignment of Sale Proceeds. Subject to compliance with applicable law and the Company’s Trading Compliance Policy, if permitted by the Company, the Grantee may satisfy the Participating Company’s tax withholding obligations in accordance with procedures established by the Company providing for delivery by the Grantee to the Company or a broker approved by the Company of properly executed instructions, in a form approved by the Company, providing for the assignment to the Company of the proceeds of a sale with respect to some or all of the shares being acquired upon settlement of Units.

7. Adjustments for Changes in Capital Structure .

Subject to any required action by the stockholders of the Company and the requirements of Section 409A of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number of Units subject to this Agreement and/or the number and kind of shares or other property to be issued in settlement of the Units, in order to prevent dilution or enlargement of the Grantee’s rights under this Agreement. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any and all new, substituted or additional securities or other property (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) to which the Grantee is entitled by reason of ownership of Units acquired pursuant to this Agreement will be immediately subject to the provisions of this Agreement on the same basis as all Units originally acquired hereunder. Any fractional Unit or share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number. Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive.

In the event of a merger or other Change in Control which does not constitute a Settlement Date, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “ Acquiror ”), shall, without the consent of the Grantee, assume or continue in full force and effect the Company’s rights and obligations under the Units then-outstanding and this Agreement or substitute for the Units then-outstanding substantially equivalent restricted stock units for Acquiror’s stock. For purposes of this Section, the Units or any portion thereof shall be deemed assumed if, following the merger or Change in Control, this Agreement, as assumed, confers the right to receive, subject to the terms and conditions of the this Agreement, for each Unit outstanding immediately prior to the merger or Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the merger or Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the settlement of the Units, for each share of Stock subject to the Unit, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the merger or Change in Control.

8. Rights as a Stockholder or Employee .

The Grantee shall have no rights as a stockholder with respect to any shares which may be issued in settlement of the Units until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares of Stock are issued, except as provided in Section 2.3 or Section 7. The Grantee understands and acknowledges that the Grantee’s Services to the Company is dictated by the Employment Agreement. Nothing in this Agreement shall confer upon the Grantee any right to continue in the Service of a Participating Company or interfere in any way with any right of a Participating Company to terminate the Grantee’s Service at any time.

Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following:

In the event that the Optionee is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Optionee and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company). Each Exercise Notice, whether electronic or written, must state the Optionee’s election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Optionee’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6 and must be accompanied by full payment of the aggregate Exercise Price for the number of shares of Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice and the aggregate Exercise Price.

4.3 Payment of Exercise Price.

(a) Forms of Consideration Authorized . Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check or in cash equivalent; (ii) if permitted by the Company and subject to the limitations contained in Section 4.3(b), by means of (1) a Cashless Exercise, (2) a Net-Exercise, or (3) a Stock Tender Exercise; or (iii) by any combination of the foregoing as approved by the Administrator.

(b) Limitations on Forms of Consideration. The Company reserves, at any and all times, the right, in its sole and absolute discretion, to establish, decline to approve or terminate any program or procedure providing for payment of the Exercise Price through any of the means described below, including with respect to the Optionee notwithstanding that such program or procedures may be available to others.

(i) Cashless Exercise. A “ Cashless Exercise ” means the delivery of a properly executed Exercise Notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to shares of Stock acquired upon the exercise of the Option in an amount not less than the aggregate Exercise Price for such shares (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System).

(ii) Net-Exercise. A “ Net-Exercise ” means the delivery of a properly executed Exercise Notice electing a procedure pursuant to which (1) the Company will reduce the number of shares otherwise issuable to the Optionee upon the exercise of the Option by the largest whole number of shares having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Optionee shall pay to the Company in cash the remaining balance of such aggregate Exercise Price not satisfied by such reduction in the number of whole shares to be issued. Following a Net-Exercise, the number of shares remaining subject to the Option, if any, shall be reduced by the sum of (1) the net number of shares issued to the Optionee upon such exercise, and (2) the number of shares deducted by the Company for payment of the aggregate Exercise Price.

(iii) Stock Tender Exercise. A “ Stock Tender Exercise ” means the delivery of a properly executed Exercise Notice accompanied by (1) the Optionee’s tender to the Company, or attestation to the ownership, in a form acceptable to the Company of whole shares of Stock having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Optionee’s payment to the Company in cash of the remaining balance of such aggregate Exercise Price not satisfied by such shares’ Fair Market Value. A Stock Tender Exercise shall not be permitted if it would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s Stock. If required by the Company, the Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for a period of time required by the Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company.

4.4 Tax Withholding .

(a) In General. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by a Participating Company, the Optionee hereby authorizes withholding from payroll and any other amounts payable to the Optionee and otherwise agrees to make adequate provision for (including by means of a Cashless Exercise to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax (including any social insurance) withholding obligations of the Participating Company Group, if any, which arise in connection with the Option. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Participating Company Group have been satisfied by the Optionee. Additionally, any taxes imposed on the Optionee due to Services to the Company (including upon the exercise of the Option) will be the sole responsibility of the Optionee (except as otherwise specified in Section 2.2).

(b) Withholding in Shares . The Company shall have the right, but not the obligation, to require the Optionee to satisfy all or any portion of a Participating Company’s tax withholding obligations upon exercise of the Option by deducting from the shares of Stock otherwise issuable to the Optionee upon such exercise a number of whole shares having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum statutory withholding rates.

4.5 Beneficial Ownership of Shares; Certificate Registration . The Optionee hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Optionee with any broker with which the Optionee has an account relationship of which the Company has notice any or all shares acquired by the Optionee pursuant to the exercise of the Option. Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, in the names of the heirs of the Optionee.

4.6 Restrictions on Grant of the Option and Issuance of Shares . The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

4.7 Fractional Shares . The Company shall not be required to issue fractional shares upon the exercise of the Option.

5. Nontransferability of the Option .

During the lifetime of the Optionee, the Option shall be exercisable only by the Optionee or the Optionee’s guardian or legal representative. The Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Optionee or the Optionee’s beneficiary, except transfer by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution.

6. Termination of the Option .

The Option shall terminate and may no longer be exercised after the first to occur of (a) the close of business on the Option Expiration Date, (b) the close of business on the last date for exercising the Option following termination of the Optionee’s Service as described in Section 7, or (c) a Change in Control to the extent provided in Section 8.

7. Effect of Termination of Service .

7.1 Option Exercisability. Except as provided in the Notice of Grant or the Employment Agreement, the Option shall terminate immediately upon the Optionee’s termination of Service to the extent that it is then unvested and shall be exercisable after the Optionee’s termination of Service to the extent it is then vested only during the applicable time period as determined below and thereafter shall terminate.

(a) Disability . Except as provided in the Notice of Grant or the Employment Agreement, if the Optionee’s Service terminates because of the Complete Disability of the Optionee, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

(b) Death . Except as provided in the Notice of Grant or the Employment Agreement, if the Optionee’s Service terminates because of the death of the Optionee, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the right to exercise the Option by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

(c) Termination for Cause. Except as provided in the Notice of Grant or the Employment Agreement, notwithstanding any other provision of this Option Agreement to the contrary, if the Optionee’s Service is terminated for Cause, the Optionee may exercise those Vested Shares as of the date Optionee’s Service is terminated for Cause at any time prior to the expiration of three (3) months after the date on which the Optionee’s Service terminated for Cause, but in any event no later than the Option Expiration Date.

(d) Other Termination of Service . If the Optionee’s Service terminates for any reason not covered by Sections 3(a), 3(b) or 3(c), the Option, to the extent unexercised and exercisable for Vested Shares by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee at any time prior to the expiration of three (3) months after the date on which the Optionee’s Service terminated or such later date as determined in accordance with Section 4.2 of the Employment Agreement, but in any event no later than the Option Expiration Date.

7.2 Extension if Exercise Prevented by Law . Notwithstanding the foregoing, other than termination of the Optionee’s Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until the later of (a) thirty (30) days after the date such exercise first would no longer be prevented by such provisions, or (b) the end of the applicable time period under Section 7.1, but in any event no later than the Option Expiration Date.

8. Effect of Change in Control .

Subject in all cases to any accelerated vesting provisions provided in the Notice of Grant or the Employment Agreement, in the event of a merger or other Change in Control the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “ Acquiror ”), may, without the consent of the Optionee, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Option or substitute for all or any portion of the Option a substantially equivalent option for the Acquiror’s stock. For purposes of this Section, the Option or any portion thereof shall be deemed assumed if, following the merger or Change in Control, the Option confers the right to receive, subject to the terms and conditions of the Employment Agreement and this Option Agreement, for each share of Stock subject to such portion of the Option immediately prior to the merger or Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the merger or Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Committee may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise of the Option, for each share of Stock subject to the Option, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the merger or Change in Control. The Option shall terminate and cease to be outstanding effective as of the time of consummation of the merger or Change in Control to the extent that the Option is neither assumed or continued by the Acquiror in connection with the merger Change in Control nor exercised as of the time of the merger or Change in Control.

9. Adjustments for Changes in Capital Structure .

Subject to any required action by the stockholders of the Company and the requirements of Sections 409A of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number, Exercise Price and/or kind of shares subject to the Option, in order to prevent dilution or enlargement of the Optionee’s rights under the Option. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number and the Exercise Price shall be rounded up to the nearest whole cent. In no event may the Exercise Price be decreased to an amount less than the par value, if any, of the Stock subject to the Option. The Committee in its sole discretion, may also make such adjustments in the terms of the Option to reflect, or related to, such changes in the capital structure of the Company or distributions as it deems appropriate. All adjustments pursuant to this Section shall be determined by the Committee, and its determination shall be final, binding and conclusive.

10. Rights as a Stockholder, Director, Employee or Consultant .

The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares are issued, except as provided in Section 9. If the Optionee is an Employee, the Optionee understands and acknowledges that, except as otherwise provided in a separate, written employment agreement between a Participating Company and the Optionee, the Optionee’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Optionee any right to continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Optionee’s Service as a Director, an Employee or Consultant, as the case may be, at any time.

11. Legends .

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of Stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section.

12. Miscellaneous Provisions .

12.1 Termination or Amendment. The Committee may terminate or amend the Option at any time; provided, however, that except as provided in Section 8 in connection with a Change in Control, no such termination or amendment may have a materially adverse effect on the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is necessary to comply with any applicable law or government regulation.

Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

2. The Award .

2.1 Grant of Units. On the Grant Date, the Grantee shall acquire, subject to the provisions of this Agreement, the Total Number of Units, subject to adjustment as provided in Section 7. Each Unit represents a right to receive one (1) share of Stock on the applicable Settlement Date and in accordance with this Agreement.

2.2 No Monetary Payment Required. The Grantee is not required to make any monetary payment (other than applicable tax withholding, if any) as a condition to receiving the Units or shares of Stock issued upon the vesting or settlement of the Units, the consideration for which shall be services to be rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable law, the Grantee shall furnish consideration in the form of cash or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the shares of Stock issued upon settlement of the Units.

2.3 Dividend Equivalent Units. On the date that the Company pays a cash dividend or other cash distribution to holders of Stock generally, the Grantee shall be credited with a number of additional whole Dividend Equivalent Units determined by dividing (a) the product of (i) the dollar amount of the cash dividend or distribution paid per share of Stock on such date and (ii) the total number of Units previously credited to the Grantee pursuant to this Agreement which have not been settled or forfeited pursuant to the Company Reacquisition Right (as defined below) as of such date, by (b) the Fair Market Value per share of Stock on such date. Any resulting fractional Dividend Equivalent Unit shall be rounded down to the nearest whole number. Such additional Dividend Equivalent Units shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the Units originally subject to this Agreement with respect to which they have been credited.

2.4 Termination of the Award. The Award shall terminate upon the first to occur of (a) the final settlement of all Vested Units in accordance with Section 5 (including a final settlement upon the termination or cessation of Grantee’s Services) or (b) the Expiration Date if settlement has not occurred on or before the Expiration Date.

3. Vesting of Units .

3.1 Satisfaction of Service Condition. Except as provided by Section 3.3 below and subject to the Grantee’s continuous Service through the applicable date set forth in the table below (each a, “ Service Date ”), the Service Condition will be satisfied, and the Units will vest, in accordance with the following schedule:

3.2 Vesting Upon Change in Control or Upon Termination Without Cause or Due to Death, Complete Disability or Good Reason. If a Change in Control occurs prior to the Expiration Date, and prior to the termination of Grantee’s Service, then the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units that are subject to vesting effective as of the date of such Change in Control. If the Grantee’s Service terminates due to the Board’s failure to nominate Grantee for re-election to the Board or the Company’s stockholders fail to re-elect Grantee to the Board, in either case other than for Cause, or if Grantee’s Service terminates as a result of the Grantee’s death or Complete Disability, then the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units that are subject to vesting effective as of the date of such termination of Service.

3.3 Effect of Termination of Service. Subject to the vesting provisions in Sections 3.1, and 3.2 above, upon the termination of Grantee’s Service (whether by the Company or by Grantee and whether for Cause or for any or no reason), then:

(a) all Units for which the Service Condition has not been satisfied as of the date of such termination of Service shall be subject to the Company Reacquisition Right (as defined in Section 4.1) immediately upon the termination of Grantee’s Service; and

(b) all Units for which the Service Condition has been satisfied as of the date of such termination of Service (including as a result of Section 3.3) shall not be subject to the Company Reacquisition Right, but instead shall remain Vested Units.

3.4 Federal Excise Tax Under Section 4999 of the Code.

(a) Excess Parachute Payment . In the event that it is determined that vesting or settlement of this award and any other payment or distribution to or for the benefit of Grantee made by the Company, by any of its affiliates, by any person who acquires ownership or effective control of the Company or ownership of a substantial portion of the Company’s assets (within the meaning of section 280G of the Code and the regulations thereunder) or by any affiliate of such person, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement, as amended, or under any other agreement, in connection with, or arising out of, Grantee’s services to the Company or a Change in Control (the “ Total Payments ”), would be subject to the excise tax imposed by section 4999 of the Code or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest or penalties, are collectively referred to as the “ Excise Tax ”), then the Company shall pay Grantee an additional amount (a “ Gross-Up Payment ”) equal to the amount that shall fund the payment by Grantee of any Excise Tax on the Total Payments as well as all income taxes imposed on the Gross-Up Payment, any Excise Tax imposed on the Gross-Up Payment and any interest or penalties imposed with respect to taxes on the Gross-Up Payment or any Excise Tax.

(b) Accounting . All mathematical determinations and all determinations of whether any of the Total Payments are “parachute payments” (within the meaning of section 280G of the Code), including all determinations of whether a Gross-Up Payment is required and of the amount of such Gross-Up Payment, shall be made by an independent accounting firm selected by the Company (the “ Accounting Firm ”), which shall provide its determination (the “ Determination ”), together with detailed supporting calculations regarding the amount of any Gross-Up Payment, both to the Company and to Grantee within seven business days of the termination of Grantee’s Service or a Change in Control of the Company, as applicable, or such earlier time as is requested by the Company or by Grantee (if Grantee reasonably believes that any of the Total Payments may be subject to the Excise Tax). If the Accounting Firm determines that no Excise Tax is payable by Grantee, it shall furnish Grantee with a written statement that such Accounting Firm has concluded that no Excise Tax is payable (including the reasons therefor) and that the Grantee has substantial authority not to report any Excise Tax on Grantee’s federal income tax return. If a Gross-Up Payment is determined to be payable, it shall be paid to the Grantee within five business days after the Determination is delivered to the Company or the Grantee and in no event later than the close of the calendar year following the calendar year in which the Grantee pays the Excise Tax (provided that such payment shall not be made prior to the date of any release or waiver executed by the Grantee in connection with a separation from the Company). Notwithstanding the foregoing, to the extent the Gross-Up Payment is subject to Section 457A of the Code, it will be paid no later than 12 months after the end of the Company’s taxable year in which the Grantee’s services to the Company terminates or the Change in Control of the Company, as applicable, occurs. Any determination by the Accounting Firm shall be binding upon the Company and the Grantee, absent manifest error.

(c) As a result of uncertainty in the application of Sections 4999 and 280G of the Code at the time of the initial Determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments not made by the Company should have been made (“ Gross-Up Underpayments ”) or that Gross-Up Payments will have been made by the Company which should not have been made (“ Gross-Up Overpayments ”). In either event, the Accounting Firm shall determine the amount of the Gross-Up Underpayment or Gross-Up Overpayment that has occurred.

(i) In the case of a Gross-Up Underpayment, the amount of such Gross-Up Underpayment shall promptly be paid by the Company to or for the benefit of Grantee.

(ii) In the case of a Gross-Up Overpayment, the Grantee shall, at the direction and expense of the Company, take such steps as are reasonably necessary (including the filing of returns and claims for refund), follow reasonable instructions from, and procedures established by, the Company and otherwise reasonably cooperate with the Company to correct such Gross-Up Overpayment; provided, however, that (i) Grantee shall in no event be obligated to return to the Company an amount greater than the net after-tax portion of the Gross-Up Overpayment that the Grantee has retained or has recovered as a refund from the applicable taxing authorities and (ii) this provision shall be interpreted in a manner consistent with the intent of this section, which is to make the Grantee whole, on an after-tax basis, for the application of the Excise Tax, it being understood that the correction of a Gross-Up Overpayment may result in the Grantee’s repaying to the Company an amount which is less than the Gross-Up Overpayment.

4. Company Reacquisition Right .

4.1 Grant of Company Reacquisition Right. In the event that the Grantee’s Service terminates for any reason, the Grantee shall forfeit and the Company shall automatically reacquire all Units for which the applicable Service Condition has not been satisfied as of the time of such termination in accordance with Section 3 (the “ Unvested Units ” ), and the Grantee shall not be entitled to any payment therefor (the “Company Reacquisition Right” ).

4.2 Dividends, Distributions and Adjustments . Upon the occurrence of a dividend or distribution to the stockholders of the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital structure of the Company as described in Section 7, any and all new, substituted or additional securities or other property to which the Grantee is entitled by reason of the Grantee’s ownership of Unvested Units shall be immediately subject to the Company Reacquisition Right and included in the terms “Units” and “Unvested Units” for all purposes of the Company Reacquisition Right with the same force and effect as the Unvested Units immediately prior to the dividend, distribution or adjustment, as the case may be. For purposes of determining the number of Units for which the applicable Service Condition has been satisfied following a dividend, distribution or adjustment, credited Service shall include all Service with any corporation which is a Participating Company at the time the Service is rendered, whether or not such corporation is a Participating Company both before and after any such event.

5. Settlement of the Units .

5.1 Issuance of Shares of Stock . Subject to the provisions of Section 5.3 below, the Company shall issue to the Grantee on the Settlement Date with respect to each Vested Unit to be settled on such date one (1) share of Stock.

5.2 Beneficial Ownership of Shares . A certificate for the shares acquired by the Grantee shall be registered in the name of the Grantee, or, if applicable, in the names of the heirs of the Grantee.

5.3 Transfer of Shares. The Grantee may not transfer the shares of Stock issued upon settlement of the Units except in compliance with applicable federal and state securities laws and the Company’s insider trading policy.

5.4 Fractional Shares. The Company shall not be required to issue fractional shares upon the settlement of the Units.

6. Tax Withholding .

The Grantee agrees to make adequate provision for the payment of any sums required to satisfy federal, state, local and foreign (including any social insurance) withholding obligations of the Participating Company, if any, which arise in connection with the grant or vesting of the Units or the issuance of shares of Stock in settlement thereof. The Company shall have no obligation to deliver shares of Stock until any tax withholding obligation of the Participating Company have been satisfied by the Grantee.

Grantee understands and agrees that the Grantee is currently an independent contractor and not an employee of the Company. As a result, the Company will not make deductions for taxes from any amounts payable to Grantee as a result of his Services to the Company or as a result of the vesting or settlement of the Units (except as otherwise specified in Section 3 or required by applicable law or regulation). Any taxes imposed on the Grantee due to Services to the Company (including upon the issuance, vesting and settlement of the Units) will be the sole responsibility of the Grantee (except as otherwise specified in Section 3).

7. Adjustments for Changes in Capital Structure .

Subject to any required action by the stockholders of the Company and the requirements of Section 409A of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number of Units subject to this Agreement and/or the number and kind of shares or other property to be issued in settlement of the Units, in order to prevent dilution or enlargement of the Grantee’s rights under this Agreement. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any and all new, substituted or additional securities or other property (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) to which the Grantee is entitled by reason of ownership of Units acquired pursuant to this Agreement will be immediately subject to the provisions of this Agreement on the same basis as all Units originally acquired hereunder. Any fractional Unit or share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number. Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive.

In the event of a merger or other Change in Control which does not constitute a Settlement Date, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “ Acquiror ”), shall, without the consent of the Grantee, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Units then-outstanding and this Agreement or substitute for all or any portion of the Units then-outstanding substantially equivalent restricted stock units for Acquiror’s stock. For purposes of this Section, the Units or any portion thereof shall be deemed assumed if, following the merger or Change in Control, this Agreement, as assumed, confers the right to receive, subject to the terms and conditions of this Agreement, for each Unit outstanding immediately prior to the merger or Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the merger or Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the settlement of the Units, for each share of Stock subject to the Unit, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the merger or Change in Control.

8. Rights as a Stockholder or Director .

The Grantee shall have no rights as a stockholder with respect to any shares which may be issued in settlement of the Units until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares of Stock are issued, except as provided in Section 2.3 or Section 7. The Grantee understands and acknowledges that the Grantee’s Services are not for any particular period of time, and that Grantee’s continued Service as a director is dependent on the continued nomination by the Company’s Board of Directors and election by the Company’s stockholders. Nothing in this Agreement shall confer upon the Grantee any right to continue in the Service of a Participating Company or interfere in any way with any right of a Participating Company to end the Grantee’s Service at any time.

9. Legends .

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock issued pursuant to this Agreement. The Grantee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to this Agreement in the possession of the Grantee in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following:

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

10. Compliance with Section 409A .

It is intended that any election, payment or benefit which is made or provided pursuant to or in connection with this Agreement that may result in or relate to the deferral of compensation within the meaning of Section 409A of the Code ( “ Section 409A Deferred Compensation ” ) shall comply in all respects with the applicable requirements of Section 409A of the Code (including applicable regulations or other administrative guidance thereunder, as determined by the Board in good faith) to avoid the unfavorable tax consequences provided therein for non-compliance. In connection with effecting such compliance with Section 409A of the Code, the following shall apply:

10.1 Separation from Service; Required Delay in Payment to Specified Grantee. Notwithstanding anything set forth herein to the contrary, no amount payable pursuant to this Agreement on account of the Grantee’s termination of Service which constitutes Section 409A Deferred Compensation shall be paid unless and until the Grantee has incurred a “separation from service” within the meaning of Section 409A of the Code. Furthermore, to the extent that the Grantee is a “specified employee” within the meaning of the Section 409A as of the date of the Grantee’s separation from service, no amount that constitutes a deferral of compensation which is payable on account of the Grantee’s separation from service shall be paid to the Grantee before the date (the “ Delayed Payment Date ” ) which is first day of the seventh month after the date of the Grantee’s separation from service or, if earlier, the date of the Grantee’s death following such separation from service. All such amounts that would, but for this Section, become payable prior to the Delayed Payment Date will be accumulated and paid on the Delayed Payment Date.

10.2 Other Changes in Time of Payment. Neither the Grantee nor the Company shall take any action to accelerate or delay the payment of any benefits under this Agreement in any manner which would not be in compliance with Section 409A of the Code.

10.3 Amendments to Comply with Section 409A; Indemnification. Notwithstanding any other provision of this Agreement to the contrary, the Company is authorized to amend this Agreement, to void or amend any election made by the Grantee under this Agreement and/or to delay the payment of any monies and/or provision of any benefits in such manner as may be determined by the Company, in its discretion, to be necessary or appropriate to comply with Section 409A of the Code without prior notice to or consent of the Grantee. The Grantee hereby releases and holds harmless the Company, its directors, officers and stockholders from any and all claims that may arise from or relate to any tax liability, penalties, interest, costs, fees or other liability incurred by the Grantee in connection with this Agreement, including as a result of the application of Section 409A of the Code.

10.4 Advice of Independent Tax Advisor. The Company has not obtained a tax ruling or other confirmation from the Internal Revenue Service with regard to the application of Section 409A to this Agreement, and the Company does not represent or warrant that this Agreement will avoid adverse tax consequences to the Grantee, including as a result of the application of Section 409A of the Code. The Grantee hereby acknowledges that he or she has been advised to seek the advice of his or her own independent tax advisor prior to entering into this Agreement and is not relying upon any representations of the Company or any of its agents as to the effect of or the advisability of entering into this Agreement.

11. Administration .

All questions of interpretation concerning this Agreement or any other form of agreement or other document employed by the Company in the administration of this Agreement shall be determined by the Board. All such determinations by the Board shall be final, binding and conclusive upon all persons having an interest in this Agreement, unless fraudulent or made in bad faith. Any and all actions, decisions and determinations taken or made by the Board in the exercise of its discretion pursuant to this Agreement or other agreement thereunder (other than determining questions of interpretation pursuant to the preceding sentence) shall be final, binding and conclusive upon all persons having an interest in this Agreement. Any officer of the Company shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the officer has apparent authority with respect to such matter, right, obligation, or election.

12. Representations and Warranties of Grantee .

In connection with the acquisition of securities pursuant to this Agreement, the Grantee hereby agrees, represents and warrants as follows:

12.1 Investment Intent. The Grantee is acquiring shares of Stock pursuant to this Agreement solely for the Grantee’s own account for investment and not with a view to or for sale in connection with any distribution of the shares or any portion thereof and not with any present intention of selling, offering to sell or otherwise disposing of or distributing the shares or any portion thereof in any transaction other than a transaction exempt from registration under the Securities Act.

By signing the Notice of Grant, the Optionee: (a) accepts the Option is subject to all of the terms and conditions of the Notice of Grant and this Option Agreement and (b) agrees to accept as binding, conclusive and final all decisions or interpretations of the Board of Directors (the “ Board ”) upon any questions arising under the Notice of Grant or this Option Agreement.

1. Definitions and Construction .

1.1 Definitions . Capitalized terms not otherwise defined in the Notice of Grant or Sections 1-12 of the Option Agreement are defined in Section 13 of the Option Agreement.

1.2 Construction . Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

2. Tax Consequences .

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

2.2 Federal Excise Tax Under Section 4999 of the Code.

(a) Excess Parachute Payment . In the event that it is determined that vesting or exercise of this award and any other payment or distribution to or for the benefit of Optionee made by the Company, by any of its affiliates, by any person who acquires ownership or effective control of the Company or ownership of a substantial portion of the Company’s assets (within the meaning of section 280G of the Code and the regulations thereunder) or by any affiliate of such person, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement, as amended, or under any other agreement, in connection with, or arising out of, Optionee’s services to the Company or a Change in Control (the “ Total Payments ”), would be subject to the excise tax imposed by section 4999 of the Code or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest or penalties, are collectively referred to as the “ Excise Tax ”), then the Company shall pay Optionee an additional amount (a “ Gross-Up Payment ”) equal to the amount that shall fund the payment by Optionee of any Excise Tax on the Total Payments as well as all income taxes imposed on the Gross-Up Payment, any Excise Tax imposed on the Gross-Up Payment and any interest or penalties imposed with respect to taxes on the Gross-Up Payment or any Excise Tax.

(b) Accounting . All mathematical determinations and all determinations of whether any of the Total Payments are “parachute payments” (within the meaning of section 280G of the Code), including all determinations of whether a Gross-Up Payment is required and of the amount of such Gross-Up Payment, shall be made by an independent accounting firm selected by the Company (the “ Accounting Firm ”), which shall provide its determination (the “ Determination ”), together with detailed supporting calculations regarding the amount of any Gross-Up Payment, both to the Company and to Optionee within seven business days of the termination of Optionee’s Service or a Change in Control of the Company, as applicable, or such earlier time as is requested by the Company or by Optionee (if Optionee reasonably believes that any of the Total Payments may be subject to the Excise Tax). If the Accounting Firm determines that no Excise Tax is payable by Optionee, it shall furnish Optionee with a written statement that such Accounting Firm has concluded that no Excise Tax is payable (including the reasons therefor) and that the Optionee has substantial authority not to report any Excise Tax on Optionee’s federal income tax return. If a Gross-Up Payment is determined to be payable, it shall be paid to the Optionee within five business days after the Determination is delivered to the Company or the Optionee and in no event later than the close of the calendar year following the calendar year in which the Optionee pays the Excise Tax (provided that such payment shall not be made prior to the date of any release or waiver executed by the Optionee in connection with a separation from the Company). Notwithstanding the foregoing, to the extent the Gross-Up Payment is subject to Section 457A of the Code, it will be paid no later than 12 months after the end of the Company’s taxable year in which the Optionee’s services to the Company terminates or the Change in Control of the Company, as applicable, occurs. Any determination by the Accounting Firm shall be binding upon the Company and the Optionee, absent manifest error.

(c) As a result of uncertainty in the application of Sections 4999 and 280G of the Code at the time of the initial Determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments not made by the Company should have been made (“ Gross-Up Underpayments ”) or that Gross-Up Payments will have been made by the Company which should not have been made (“ Gross-Up Overpayments ”). In either event, the Accounting Firm shall determine the amount of the Gross-Up Underpayment or Gross-Up Overpayment that has occurred.

(i) In the case of a Gross-Up Underpayment, the amount of such Gross-Up Underpayment shall promptly be paid by the Company to or for the benefit of Optionee.

(ii) In the case of a Gross-Up Overpayment, the Optionee shall, at the direction and expense of the Company, take such steps as are reasonably necessary (including the filing of returns and claims for refund), follow reasonable instructions from, and procedures established by, the Company and otherwise reasonably cooperate with the Company to correct such Gross-Up Overpayment; provided, however, that (i) Optionee shall in no event be obligated to return to the Company an amount greater than the net after-tax portion of the Gross-Up Overpayment that the Optionee has retained or has recovered as a refund from the applicable taxing authorities and (ii) this provision shall be interpreted in a manner consistent with the intent of this section, which is to make the Optionee whole, on an after-tax basis, for the application of the Excise Tax, it being understood that the correction of a Gross-Up Overpayment may result in the Optionee’s repaying to the Company an amount which is less than the Gross-Up Overpayment.

3. Administration .

All questions of interpretation concerning the Notice of Grant, this Option Agreement, or any other form of agreement or other document employed by the Company in the administration of the Option shall be determined by the Board. All such determinations by the Board shall be final, binding and conclusive upon all persons having an interest in the Option, unless fraudulent or made in bad faith. Any and all actions, decisions and determinations taken or made by the Board in the exercise of its discretion pursuant to the Option or other agreement thereunder (other than determining questions of interpretation pursuant to the preceding sentence) shall be final, binding and conclusive upon all persons having an interest in the Option. Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, or election.

4. Exercise of the Option .

4.1 Right to Exercise . Except as otherwise provided herein, the Option shall be exercisable on and after the Date of Grant and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the number of Vested Shares less the number of shares previously acquired upon exercise of the Option. In no event shall the Option be exercisable for more shares than the Number of Option Shares, as adjusted pursuant to Section 9.

4.2 Method of Exercise . Exercise of the Option shall be by means of electronic or written notice (the “ Exercise Notice ”) in a form authorized by the Company. An electronic Exercise Notice must be digitally signed or authenticated by the Optionee in such manner as required by the notice and transmitted to the Company or an authorized representative of the Company (including a third-party administrator designated by the Company). In the event that the Optionee is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Optionee and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company). Each Exercise Notice, whether electronic or written, must state the Optionee’s election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Optionee’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6 and must be accompanied by full payment of the aggregate Exercise Price for the number of shares of Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice and the aggregate Exercise Price.

4.3 Payment of Exercise Price.

(a) Forms of Consideration Authorized . Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check or in cash equivalent; (ii) if permitted by the Company and subject to the limitations contained in Section 4.3(b), by means of (1) a Cashless Exercise, (2) a Net-Exercise, or (3) a Stock Tender Exercise; or (iii) by any combination of the foregoing as approved by the Board.

(b) Limitations on Forms of Consideration. The Company reserves, at any and all times, the right, in its sole and absolute discretion, to establish, decline to approve or terminate any program or procedure providing for payment of the Exercise Price through any of the means described below, including with respect to the Optionee notwithstanding that such program or procedures may be available to others.

(i) Cashless Exercise. A “ Cashless Exercise ” means the delivery of a properly executed Exercise Notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to shares of Stock acquired upon the exercise of the Option in an amount not less than the aggregate Exercise Price for such shares (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System).

(ii) Net-Exercise. A “ Net-Exercise ” means the delivery of a properly executed Exercise Notice electing a procedure pursuant to which (1) the Company will reduce the number of shares otherwise issuable to the Optionee upon the exercise of the Option by the largest whole number of shares having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Optionee shall pay to the Company in cash the remaining balance of such aggregate Exercise Price not satisfied by such reduction in the number of whole shares to be issued. Following a Net-Exercise, the number of shares remaining subject to the Option, if any, shall be reduced by the sum of (1) the net number of shares issued to the Optionee upon such exercise, and (2) the number of shares deducted by the Company for payment of the aggregate Exercise Price.

(iii) Stock Tender Exercise. A “ Stock Tender Exercise ” means the delivery of a properly executed Exercise Notice accompanied by (1) the Optionee’s tender to the Company, or attestation to the ownership, in a form acceptable to the Company of whole shares of Stock having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Optionee’s payment to the Company in cash of the remaining balance of such aggregate Exercise Price not satisfied by such shares’ Fair Market Value. A Stock Tender Exercise shall not be permitted if it would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s Stock. If required by the Company, the Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for a period of time required by the Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company.

4.4 Tax Withholding . The Optionee agrees to make adequate provision for the payment of any sums required to satisfy federal, state, local and foreign (including any social insurance) withholding obligations of the Participating Company, if any, which arise in connection with the exercise of the Option. The Company shall have no obligation to deliver shares of Stock until any tax withholding obligation of the Participating Company have been satisfied by the Option. Optionee understands and agrees that the Optionee is currently an independent contractor and not an employee of the Company. As a result, the Company will not make deductions for taxes from any amounts payable to Optionee as a result of his Services to the Company or as a result of the exercise of the Option (except as otherwise specified in Section 2.2 or required by applicable law or regulation). Any taxes imposed on the Optionee due to Services to the Company (including upon the exercise of the Option) will be the sole responsibility of the Optionee (except as otherwise specified in Section 2.2).

4.5 Beneficial Ownership of Shares; Certificate Registration . The Optionee hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Optionee with any broker with which the Optionee has an account relationship of which the Company has notice any or all shares acquired by the Optionee pursuant to the exercise of the Option. Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, in the names of the heirs of the Optionee.

4.6 Restrictions on Grant of the Option and Issuance of Shares . The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

4.7 Fractional Shares . The Company shall not be required to issue fractional shares upon the exercise of the Option.

5. Nontransferability of the Option .

During the lifetime of the Optionee, the Option shall be exercisable only by the Optionee or the Optionee’s guardian or legal representative. The Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Optionee or the Optionee’s beneficiary, except transfer by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution.

6. Termination of the Option .

The Option shall terminate and may no longer be exercised after the first to occur of (a) the close of business on the Option Expiration Date, (b) the close of business on the last date for exercising the Option following termination of the Optionee’s Service as described in Section 7, or (c) a Change in Control to the extent provided in Section 8.

7. Effect of Termination of Service .

7.1 Option Exercisability. Except as provided in the Notice of Grant, the Option shall terminate immediately upon the Optionee’s termination of Service to the extent that it is then unvested and shall be exercisable after the Optionee’s termination of Service to the extent it is then vested only during the applicable time period as determined below and thereafter shall terminate.

(a) Disability . Except as provided in the Notice of Grant, if the Optionee’s Service terminates because of the Complete Disability of the Optionee, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

(b) Death . Except as provided in the Notice of Grant, if the Optionee’s Service terminates because of the death of the Optionee, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the right to exercise the Option by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

(c) Termination for Cause. Except as provided in the Notice of Grant, notwithstanding any other provision of this Option Agreement to the contrary, if the Optionee’s Service is terminated for Cause, the Optionee may exercise those Vested Shares as of the date Optionee’s Service is terminated for Cause at any time prior to the expiration of three (3) months after the date on which the Optionee’s Service terminated for Cause, but in any event no later than the Option Expiration Date.

(d) Other Termination of Service . If the Optionee’s Service terminates for any reason not covered by Sections 3(a), 3(b) or 3(c), the Option, to the extent unexercised and exercisable for Vested Shares by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee at any time prior to the expiration of three (3) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date.

7.2 Extension if Exercise Prevented by Law . Notwithstanding the foregoing, other than termination of the Optionee’s Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until the later of (a) thirty (30) days after the date such exercise first would no longer be prevented by such provisions, or (b) the end of the applicable time period under Section 7.1, but in any event no later than the Option Expiration Date.

8. Effect of Change in Control .

Subject in all cases to any accelerated vesting provisions provided in the Notice of Grant, in the event of a merger or other Change in Control the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “ Acquiror ”), may, without the consent of the Optionee, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Option or substitute for all or any portion of the Option a substantially equivalent option for the Acquiror’s stock. For purposes of this Section, the Option or any portion thereof shall be deemed assumed if, following the merger or Change in Control, the Option confers the right to receive, subject to the terms and conditions of this Option Agreement, for each share of Stock subject to such portion of the Option immediately prior to the merger or Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the merger or Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise of the Option, for each share of Stock subject to the Option, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the merger or Change in Control. The Option shall terminate and cease to be outstanding effective as of the time of consummation of the merger or Change in Control to the extent that the Option is neither assumed or continued by the Acquiror in connection with the merger Change in Control nor exercised as of the time of the merger or Change in Control.

9. Adjustments for Changes in Capital Structure .

Subject to any required action by the stockholders of the Company and the requirements of Sections 409A of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number, Exercise Price and/or kind of shares subject to the Option, in order to prevent dilution or enlargement of the Optionee’s rights under the Option. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number and the Exercise Price shall be rounded up to the nearest whole cent. In no event may the Exercise Price be decreased to an amount less than the par value, if any, of the Stock subject to the Option. The Board in its sole discretion, may also make such adjustments in the terms of the Option to reflect, or related to, such changes in the capital structure of the Company or distributions as it deems appropriate. All adjustments pursuant to this Section shall be determined by the Board, and its determination shall be final, binding and conclusive.

10. Rights as a Stockholder, Director, or Director .

The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares are issued, except as provided in Section 9. The Optionee understands and acknowledges that the Optionee’s Services are not for any particular period of time, and that Optionee’s continued Service as a director is dependent on the continued nomination by the Board of Directors and election by the Company’s stockholders. Nothing in this Agreement shall confer upon the Optionee any right to continue in the Service of a Participating Company or interfere in any way with any right of a Participating Company to end the Optionee’s Service at any time.

11. Legends .

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of Stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section.

12. Miscellaneous Provisions .

12.1 Termination or Amendment. The Board may terminate or amend the Option at any time; provided, however, that except as provided in Section 8 in connection with a Change in Control, no such termination or amendment may have a materially adverse effect on the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is necessary to comply with any applicable law or government regulation. No amendment or addition to this Option Agreement shall be effective unless in writing.

12.2 Further Instruments. The parties hereto agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Option Agreement.

The Optionee further acknowledges that the Optionee will be provided with a paper copy of any documents if the attempted electronic delivery of such documents fails. Similarly, the Optionee understands that the Optionee must provide the Company or any designated third party administrator with a paper copy of any documents if the attempted electronic delivery of such documents fails. The Optionee may revoke his or her consent to the electronic delivery of documents described in Section 12.4(a) or may change the electronic mail address to which such documents are to be delivered (if the Optionee has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail address by telephone, postal service or electronic mail. Finally, the Optionee understands that he or she is not required to consent to electronic delivery of documents described in Section 12.4(a).

12.5 Integrated Agreement.
