The Investors may elect to purchase all or any portion of the Shares that the Company has not elected to purchase by written notice to the Employee delivered at any time on or before the 80th day after the Determination Date (the “Second Option Period”).

(b) Limited Right of the Employee to Require the Company to Repurchase Shares. If the Employee’s employment with the Company is terminated by reason of the Disability or death of the Employee and the right of repurchase pursuant to Section 5(a) has been exercised with respect to fewer than all of the number of Shares set forth on the signature page hereof (as may be adjusted pursuant to Section 3.3 of the Stock Incentive Plan), the Employee may, by written notice delivered to the Company within 30 days following the expiration of the Second Option Period,

5

require the Company or the Investors, as applicable, to purchase a number of the Employee’s Shares equal to the number of Shares set forth on the signature page hereof minus the number of Shares repurchased pursuant to Section 5(a).

(c) Purchase Price. The purchase price per Share pursuant to this Section 5 shall equal the Fair Market Value as of the later of (i) the effective date of the Employee’s termination of employment (determined without regard to any statutory or deemed or express contractual notice period) and (ii) six months and one day from the date of the Employee’s acquisition of the Shares pursuant to this Agreement (such date, the “Determination Date”), provided that if the Employee’s employment is terminated by the Company for Cause, the purchase price per Share shall equal the lesser of (i) the Fair Market Value of such Share as of the Determination Date and (ii) the price at which the Employee purchased such Share from the Company pursuant to this Agreement.

(d) Closing of Purchase; Payment of Purchase Price. Subject to Section 5(f), the closing of a purchase pursuant to this Section 5 shall take place at the principal office of the Company no later than the 90 th day following the Determination Date (or, in the case of a purchase pursuant to Section 5(b), no later than 10 business days following the Company’s receipt of written notice from the Employee pursuant to Section 5(b)). At the closing, (i) the Company or the Investors, as the case may be, shall, subject to Section 5(e), pay the Purchase Price to the Employee and (ii) if the Employee actually holds any certificates or other instruments representing the Shares so purchased, the Employee shall deliver to the Company such certificates or other instruments, appropriately endorsed by the Employee or directing that the shares be so transferred to the purchaser thereof, as the Company may reasonably require.

(e) Application of the Purchase Price to Certain Loans or Other Obligations. The Company and the Investors shall be entitled to apply any amounts otherwise payable pursuant to this Section 5 to discharge any indebtedness of the Employee to the Company or any of its Subsidiaries or indebtedness that is guaranteed by the Company or any of its Subsidiaries, or to offset any such amounts against any other obligations of the Employee to the Company or any of its Subsidiaries.

(f) Certain Restrictions on Repurchases; Delay of Repurchase. Notwithstanding any other provision of this Agreement, the Company shall not be permitted or obligated to make any payment with respect to a repurchase of any Shares from the Employee if (i) such repurchase (or the payment of a dividend by a Subsidiary to the Company to fund such

6

repurchase) would result in a violation of the terms or provisions of, or result in a default or an event of default under any of the Financing Agreements, (ii) such repurchase would violate any of the terms or provisions of the Certificate of Incorporation and By-laws of the Company or (iii) the Company has no funds legally available to make such payment under the General Corporation Law of the State of Delaware. If payment with respect to a repurchase by the Company otherwise permitted or required under this Section 5 is prevented by the terms of the preceding sentence, (i) the payment of the applicable Purchase Price shall be postponed and will take place at the first opportunity thereafter when the Company has funds legally available to make such payment and when such payment will not result in any default, event of default or violation under any of the Financing Agreements or in a violation of any term or provision of the Certificate of Incorporation or By-laws, (ii) such repurchase obligation shall rank against other similar repurchase obligations with respect to Common Stock according to priority in time of the effective date of the termination of employment giving rise to such repurchase (provided that any repurchase commitment arising from Disability or death shall have priority over any other repurchase obligation) and (iii) the Purchase Price, except in the case of a termination for Cause, shall be increased by an amount equal to interest on such Purchase Price for the period during which payment is delayed at an annual rate equal to the weighted average cost of the Company’s senior secured bank indebtedness outstanding during the delay period.

(g) Right to Retain Shares. If the options of the Company and the Investors to purchase the Shares pursuant to this Section 5 are not exercised within the applicable time periods specified in Section 5(a) with respect to all of the Shares, the Employee shall be entitled to retain the remaining Shares, although those Shares shall remain subject to all of the other provisions of this Agreement.

(h) Notice of Termination; Etc. Prior to a Public Offering, the Company shall give prompt written notice to the Investors of any termination of the Employee’s employment with the Company and of the Company’s decision whether or not to purchase Shares pursuant to Section 5(a).

(i) Expiration upon a Public Offering. The provisions of this Section 5 shall terminate upon a Public Offering, provided that such termination shall not affect the Company’s repurchase right following a termination for Cause that was effective (or deemed to be effective) prior to such Public Offering or any payment obligation postponed pursuant to Section 5(f).

7

(j) Allocation of Purchase Rights. The Employee acknowledges and agrees that the Investors may allocate their purchase rights under this Section 5, as among themselves, in such manner as they, in their sole discretion, may agree from time to time, provided that in the event the Investors do not reach an agreement with respect to such allocation prior to the time at which any such purchase would occur, the rights shall be allocated pro rata between the Investors based on their ownership of the Company’s Common Stock at the time of such purchase (including shares of preferred stock convertible into Common Stock, on an as-converted basis).

The preceding sentence shall not limit the Company’s or the Investors’ rights to recover damages (or the amount thereof) from the Employee.

(e) Expiration on a Public Offering. The provisions of this Section 7 shall terminate and cease to have further effect upon the consummation of a Public Offering; provided that such termination shall not affect any right to receive or seek damages or purchase Shares pursuant to Section 7(d).
