(c) there is no established market for the Units and it is not anticipated that there will be any public market for the Units in the foreseeable future;

(d) a restrictive legend in the form set forth below and the legends set forth in Sections 9.2(a) and (b) of the Securityholders Agreement shall be placed on the certificates, if any, representing the Units:

(e) Executive is or is not an “accredited investor” under the Securities Act, as indicated on the Master Signature Page.

4. Certain Sales and Forfeitures Upon Termination of Service.

4.1 Call Option.

(a) If, prior to a Sale of the Company, Executive’s service with the Company and its Subsidiaries terminates for any of the reasons set forth in clauses (i), (ii) or (iii), the Company shall have the right and option, but not the obligation, to purchase for a period commencing on the Termination Date and ending on the later of (I) 90 days following the Termination Date and (II) 211 days following the Closing Date (such period, the “Call Period”), and each member of the Executive Group shall be required to sell to the Company, any or all of such Units then held by such member of the Executive Group (it being understood that if Units subject to repurchase hereunder may be repurchased at different prices, the Company may elect to repurchase only the portion of the Units subject to repurchase hereunder at the lower price), at a price per Unit equal to the applicable purchase price determined pursuant to Section 4.1(c):

(i) if Executive’s service with the Company and its Subsidiaries terminates due to the Disability or death of Executive;

(ii) if Executive’s service with the Company and its Subsidiaries is terminated by the Company and its Subsidiaries without Cause; or

(iii) if Executive’s service with the Company and its Subsidiaries is terminated (A) by the Company or any of its Subsidiaries for Cause or (B) by Executive for any other reason not set forth in Section 4.1(a)(i) or Section 4.1(a)(ii).

(b) If the Company desires to exercise its option to purchase Units pursuant to this Section 4.1 the Company shall, not later than 30 days prior to the end of the Call Period, send written notice to each member of the Executive Group of its intention to purchase all or a portion of the Units, specifying the number of Units to be purchased (the “Call Notice”). The closing of the purchase shall take place at the principal office of the Company or one of its Subsidiaries on a date specified by the Company no later than the 30th day after the giving of the Call Notice.

(i) with respect to a purchase of all or any portion of the Units (whether vested or unvested), in the case of a termination of service described in Section 4.1(a)(iii)(A), a price per Unit equal to the lesser of (A) Fair Market Value (measured as of the date the Units are repurchased) and (B) Cost;

(ii) with respect to a purchase of all or any portion of the Unvested Units, in the case of a termination of service described in Section 4.1(a)(i), Section 4.1(a)(ii) or Section 4.1(a)(iii)(B), a price per Unvested Unit equal to the lesser of (A) Fair Market Value (measured as of the date the Unvested Units are repurchased) and (B) Cost; and

(iii) with respect to a purchase of all or any portion of the Vested Units, in the case of a termination of service described in Section 4.1(a)(i), Section 4.1(a)(ii) or Section 4.1(a)(iii)(B), a price per Vested Unit equal to Fair Market Value (measured as of the date the Unvested Units are repurchased).

4.2 Obligation to Sell Several. If there is more than one member of the Executive Group, the failure of any one member thereof to perform its obligations hereunder shall not excuse or affect the obligations of any other member thereof, and the closing of the purchases from such other members by the Company shall not excuse, or constitute a waiver of its rights against, the defaulting member.

5. Payment for Units. (a) Except as otherwise provided in this Section 5, if at any time the Company elects 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 Executive to the Company or any of its Subsidiaries (which indebtedness shall be applied pro rata against the proceeds receivable by each member of the Executive Group receiving consideration in such repurchase) and (ii) then, either (x) by the Company’s delivery of a check or wire transfer of immediately available funds or (y) by the Company’s delivery of shares of capital stock of PGA Holdings (“Holdings Shares”) with a fair market value (as determined by the Board) equal to the remainder of the purchase price, if any, against delivery of the certificates or other instruments, if any, representing the Units so purchased, duly endorsed; provided, that if Holdings Shares are issued pursuant to this Section 5, the Company shall be obligated to cause PGA Holdings to immediately repurchase, and Executive shall be obligated to sell, such Holdings Shares for a price equal to the aforementioned fair market value of such Holdings Shares, to be paid by check or wire transfer of immediately available funds.

(b) Notwithstanding anything herein to the contrary, (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 employees or other consultants 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, (C) in a violation of the LLC Agreement, or (D) in 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, in each case which prohibits either of the cash payments referred to in clause (ii) of Section 5(a) (either directly or indirectly as a result of the prohibition of a related cash dividend or distribution), the portion of the applicable cash payment so prohibited shall 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, which note shall (x) (I) be payable, in the event of a termination of service referenced in Sections 4.1(a)(i), 4.1(a)(ii) and 4.1(a)(iii)(B), as soon as the conditions set forth in this Section 5(b) no longer exist and (II) accrue interest, compounded annually, payable concurrently with the payment of principal, at the prevailing interest rate under the Company’s senior debt financing documents as in effect on the date of issuance, but in no event shall such interest rate exceed LIBOR plus four percent (4%) or (y) (I) be payable, in the event of a termination of service referenced in Section 4.1(a)(iii)(A), on the fifth anniversary of the issuance thereof, and (II) accrue interest, compounded annually, payable concurrently with the payment of principal, at the applicable Applicable Federal Rate on the date of issuance. Notwithstanding the foregoing, if any of the conditions set forth in preceding sentence exists which prohibits such payment by delivery of a Junior Subordinated Note, the portion of the payment so prohibited shall be made, to the extent such payment is not prohibited, by the Company’s delivery of a new class of preferred units of the Company that will be senior to all other classes of units in the Company (“New Preferred Units”) having an aggregate liquidation preference equal to the balance of the purchase price and accruing dividends annually at a yield equivalent to the interest rate that would have been payable on the aforementioned Junior Subordinated Note. Notwithstanding anything herein to the contrary, in the case of a purchase of Units pursuant to Section 4.1(a)(iii)(A), the Company shall 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, compounded annually, payable concurrently with the payment of principal, at the applicable Applicable Federal Rate on the date of issuance; provided that if any of the conditions set forth in the first sentence of this Section 5(b) exists which prohibits such payment by delivery of a Junior Subordinated Note, the portion of the payment so prohibited shall be made, to the extent such payment is not prohibited, by the Company’s delivery of New Preferred Units having an aggregate liquidation preference equal to the balance of the purchase price and accruing dividends, compounded annually, at a yield equivalent to the interest rate that would have been payable on the aforementioned Junior Subordinated Note. The Company shall use its reasonable efforts (or shall cause PGA Holdings to use its reasonable efforts) to repurchase Units pursuant to Section 4.1(a)(i), Section 4.1(a)(ii) or Section 4.1(a)(iii)(B) with cash and/or to prepay any Junior Subordinated Notes or redeem any New Preferred Units issued in connection with such repurchase of Units. The Company shall have the right set forth in clause (i) of Section 5(a) whether or not the member of the Executive Group selling such Units is an obligor of the Company. Any Junior Subordinated Note (or New Preferred Units issued in lieu thereof) shall be prepaid (or redeemed) 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 New

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 New Preferred Units issued in lieu thereof) also shall be prepaid (or redeemed) upon the consummation of an initial Public Offering 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 New Preferred Units issued in lieu thereof) shall be cancelled in exchange for such other non-cash consideration received by unitholders in the initial Public Offering having a fair market value equal to the principal of and accrued interest on the note. The principal of and accrued interest on any such note may be prepaid (and New 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 a cash distribution) is required to be paid on any Junior Subordinated Note (or New Preferred Units issued in lieu thereof) and any of the conditions set forth in the first sentence of this Section 5(b) exists or if any such cash payment would result in adverse accounting treatment for the Company which prohibits the payment of such interest (or distributions) in cash, such interest may be cumulated and accrued until and to the extent that such prohibition no longer exists.

6. Miscellaneous.

6.1 Withholding/Payment of Taxes. Executive may be required to pay to the Company or any Affiliate and the Company shall have the right and is hereby authorized to withhold, any applicable withholding taxes in respect of the Units, their grant or vesting or any payment or transfer with respect to the Units and to take such action as may be necessary in the opinion of the Board to satisfy all obligations for the payment of any such withholding taxes; provided, however, that Executive shall be permitted to satisfy Executive’s withholding tax obligation, if any, with respect to such Units by providing notice in writing that Executive elects to have the number of Units that would otherwise be issued to Executive reduced by a number of Units having an equivalent Fair Market Value to the payment that would otherwise be made by Executive to the Company pursuant to this Section 6.1. In connection with the foregoing, Executive may, at her option, elect to recognize the fair value of the Units upon the Closing Date pursuant to Section 83 of the Code. If Executive makes such election pursuant to Section 83 of the Code, she shall notify the Company as soon as practicable and in no event later than 30 days after making such election. Executive is hereby advised to seek her own tax counsel regarding the taxation of the grant of Units made hereunder.
