5.                                       Certain Limitations on the Company’s Obligations to Purchase Units.

5.1                                 Deferral of Purchases. (a)  Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to purchase any Units at any time pursuant to Section 4, regardless of whether it has delivered a notice of its election to purchase any such Units, (i) to the extent that the purchase of such Units or the payment to the Company or one of its subsidiaries of a cash dividend or distribution by a subsidiary of the Company to fund such purchase (together with any other purchases of Units pursuant to Section 4 or pursuant to similar provisions in agreements with other employees of the Company and its subsidiaries of which the Company has at such time been given or has given notice and together with cash dividends and distributions to fund such other purchases) would result (A) in a violation of any law, statute, rule, regulation, policy, order, writ, injunction, decree or judgment promulgated or entered by any federal, state, local or foreign court or governmental authority applicable to the Company or any of its subsidiaries or any of its or their property, (B) after giving effect thereto, in a Financing Default or (C) adverse accounting treatment for the Company, or (ii) if immediately prior to such purchase there exists a Financing Default which prohibits such purchase, dividend or distribution. The Company shall within fifteen days of learning of any such fact so notify the members of the Director Group that it is not obligated to purchase units hereunder.

(b)                                 Notwithstanding anything to the contrary contained in Section 4, any Units which a member of the Director Group has elected to sell to the Company or which the Company has elected to purchase from members of the Director Group, but which in accordance with Section 5.1(a) are not purchased at the applicable time provided in Section 4, shall be purchased by the Company for the applicable purchase price, together with interest thereon at the Applicable Federal Rate as in effect on the date such purchase is so deferred on or prior to the fifteenth day after such date or dates that (after taking into account any purchases (and related dividends and distributions) to be made at such time pursuant to agreements with other employees of the Company and its subsidiaries) the purchase of such Units (and related dividends and distributions) are no longer prohibited under Section 5.1(a), and the Company shall give the members of the Director Group five days prior notice of any such purchase.

5.2                                 Payment for Units. If at any time the Company elects or is required to purchase any Units pursuant to Section 4, the Company shall pay the purchase price for the Units it purchases (i) first, by the cancellation of any indebtedness, if any, owing from the Director to the Company or any of its subsidiaries (which indebtedness shall be applied pro rata against the proceeds receivable by each member of the Director Group receiving consideration in such repurchase) and (ii) then, by the Company’s delivery of a check or wire transfer of immediately available funds for the remainder of the purchase price, if any, against delivery of the certificates or other instruments representing the Units so purchased, duly endorsed; provided that if any of the conditions set forth in Section 5.1(a) exists which prohibits such cash payment (either directly or indirectly as a result of the prohibition of a related cash dividend or distribution), the portion of the cash payment so prohibited may be made, to the extent such payment is not prohibited, by the Company’s delivery of a junior subordinated promissory note (which shall be subordinated and subject in right of payment to the prior payment of any debt outstanding under the Financing Agreements and any modifications, renewals, extensions, replacements and refunding of all such indebtedness) of the Company (a “Junior Subordinated Note”) in a principal amount equal to the balance of the purchase price, payable (x) in the event of a termination of employment referenced in Section 4.2(a)(i) and (ii), as soon as the conditions set forth in Section 5.1(a) no longer exist or (x) in the event of a termination of the Director’s service as a member of the Board referenced in Section 4.2(a)(iii), on the fifth anniversary of the issuance thereof, and bearing interest payable annually at the Applicable Federal Rate on the date of issuance; provided further that if any of the conditions set forth in Section 5.1(a) exists which prohibits such payment (or the payment described in the next proviso) by delivery of a Junior Subordinated Note, the portion of the payment so prohibited may be made, to the extent such payment is not prohibited, by the Company’s delivery of preferred units of the Company having an aggregate liquidation preference equal to the balance of the purchase price; provided further that in the case of a purchase pursuant to Section 4.2(a)(iii) the Company may elect at any time to deliver a Junior Subordinated Note in a principal amount equal to all or a portion of the cash purchase price (in lieu of paying such portion of the purchase price in cash), which Junior Subordinated Note shall mature on the fifth anniversary of its issuance and accrue interest annually at the Applicable Federal Rate on the date of issuance, which interest shall be payable at maturity. The Company shall use its reasonable efforts to repurchase Units pursuant to Section 4.1(a) or Section 4.2(a)(i) or Section 4.2(a)(ii) with cash and/or to prepay any Junior Subordinated Notes or redeem any preferred units issued in connection with a repurchase of Units pursuant to Section 4.1(a) or Section 4.2(a)(i) or Section 4.2(a)(ii). The Company shall have the right set forth in clause (i) of the first sentence of this Section 5.2 whether or not the member of the Director Group selling such units is an obligor of the Company. Any Junior Subordinated Note (or preferred units issued in lieu thereof) shall become prepayable (or redeemable) upon a Sale of the Company from net cash proceeds, if any, payable to the Company or its unitholders; to the extent that sufficient net cash proceeds are not so payable, the Junior Subordinated Note (or preferred units issued in lieu thereof) shall be cancelled in exchange for such other non-cash consideration received by unitholders in the Sale of the Company having a fair market value equal to the principal of and accrued interest on the note. Any Junior Subordinated Note (or preferred units issued in lieu thereof) also shall become prepayable upon the consummation of an initial Public Offering. The principal of and accrued interest on any such note may be prepaid (and preferred units issued in lieu thereof may be

redeemed) in whole or in part at any time at the option of the Company. If interest (or cash dividends) is required to be paid on any Junior Subordinated Note (or preferred units issued in lieu thereof) prior to maturity and any of the conditions set forth in Section 5.1(a) exists or if any such cash payment would result in adverse accounting treatment for the Company which prohibits the payment of such interest (or dividends) in cash, such interest may be cumulated and accrued until and to the extent that such prohibition no longer exists.

6.                                       Miscellaneous.

6.1                                 Transfers to Permitted Transferees. Prior to the transfer of Units to a Permitted Transferee (other than a transfer subsequent to a Sale of the Company), the Director shall deliver to the Company a written agreement of the proposed transferee (a) evidencing such Person’s undertaking to be bound by the terms of this Agreement and (b) acknowledging that the Units transferred to such Person will continue to be Units for purposes of this Agreement in the hands of such Person. Any transfer or attempted transfer of Units in violation of any provision of this Agreement or the Securityholders Agreement shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Units as the owner of such Units for any purpose.

6.2                                 Recapitalizations, Exchanges, Etc., Affecting Units.
