To the extent there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to fully satisfy all of the payment obligations to be made in cash by the Exchange Agent hereunder, Parent shall promptly replace or restore the cash in the Exchange Fund so that the Exchange Fund is at all times maintained at a level sufficient for the Exchange Agent to fully satisfy such cash payment obligations. No investment losses resulting from investment of the Exchange Fund shall diminish the rights of any former holder of Eligible Units to receive the Merger Consideration as provided in this Agreement.

5.2 Procedure s for Surrender .

Upon surrender to the Exchange Agent of a Certificate (or satisfaction of the conditions provided in Section 5.7 in lieu of a Certificate) together with a duly executed and completed Letter of Transmittal and such other documents as may reasonably be required pursuant to such instructions, the Surviving Entity shall cause the Exchange Agent to mail to each holder of record of any such Certificate in exchange therefore, as promptly as reasonably practicable thereafter, (x) a statement reflecting the number of whole shares of Parent Common Stock, if any, that such holder is entitled to receive pursuant to ARTICLE IV in the name of such record holder and (y) a check in the amount (after giving effect to any required Tax withholdings as provided in Section 5.8) of (A) any cash in lieu of fractional shares plus (B) any unpaid dividends or other distributions that such holder has the right to receive pursuant to this ARTICLE V.

Notwithstanding the foregoing, any holder of an Eligible Unit that is evidenced by both a Certificate and a book-entry account shall not receive the notice, statement and check contemplated by the immediately preceding sentence with respect to such Eligible Unit, but shall surrender the applicable Certificate in accordance with the procedures set forth in Section 5.2(a) to receive the Merger Consideration and any other amounts due under this Agreement with respect to such Eligible Unit, and no additional Merger Consideration or other amounts under this Agreement will accrue or be payable to the book-entry account for such Eligible Unit.

(c) With respect to Book-Entry Units held through DTC, Parent and the Partnership shall cooperate to establish procedures with the Exchange Agent and DTC to ensure that the Exchange Agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the Closing Date, upon surrender of Eligible Units held of record by DTC or its nominees in accordance with DTC’s customary surrender procedures, the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, that such holder has the right to receive pursuant to this ARTICLE V.

(d) No interest will be paid or accrued on any amount payable for Eligible Units pursuant to this ARTICLE V.

5.3 Distributions with Respect to Unsurrendered Certificates . All shares of Parent Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by Parent in respect of the Parent Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares issuable pursuant to this Agreement. Subject to Section 5.5, no dividends or other distributions in respect of shares of Parent Common Stock shall be paid to any holder with respect to any unsurrendered Certificate until the Certificate (or satisfaction of the conditions provided in Section 5.7 in lieu of a Certificate) is surrendered for exchange in accordance with this ARTICLE V. Subject to applicable Law, following such surrender, dividends or distributions with respect to the Parent Common Stock issued in exchange for Eligible Units in accordance with this ARTICLE V shall be paid to the holders of record of such Eligible Units, without interest, (a) promptly after the time of such surrender for any dividends or other distributions with a record date after the Effective Time but a payment date prior to surrender and (b) at the appropriate payment date for any dividends or other distributions payable with respect to shares of Parent Common Stock with a record date after the Effective Time and prior to surrender, but with a payment date subsequent to surrender.

5.4 Transfers .

(a) From and after the Effective Time, there shall be no transfers on the stock transfer books of the Partnership of the Eligible Units that were outstanding immediately prior to the Effective Time. From and after the Effective Time, the holders of Certificates or Book-Entry Units shall cease to have any rights with respect to such Eligible Units except as otherwise provided herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Entity for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(b) With respect to Certificates, in the event of a transfer of ownership of any Certificate that is not registered in the transfer books of the Partnership as of the Effective Time, the proper number of shares of Parent Common Stock, together with a check for any cash (after giving effect to any required Tax withholdings as provided in Section 5.8) to be paid upon due surrender of the Certificate and any dividends or distributions in respect thereof, may be issued or paid to such a transferee if the Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid or are not applicable, in each case, in form and substance, reasonably satisfactory to the Exchange Agent. Until surrendered as contemplated by this Section 5.4, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, payable or issuable pursuant to this ARTICLE V.

(c) With respect to Book-Entry Units, payment of the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, payable or issuable pursuant to this ARTICLE V, shall only be made to the Person in whose name such Book-Entry Units are registered in the stock transfer books of the Partnership as of the Effective Time.

5.5 Fractional Shares . Notwithstanding anything in this Agreement to the contrary, no fractional shares of Parent Common Stock will be issued upon the conversion of Common Units pursuant to Section 4.1. All fractional shares of Parent Common Stock that a holder of Eligible Units would be otherwise entitled to receive pursuant to Section 4.1, but for this Section 5.5, shall be aggregated and rounded to three decimal places, and such holder shall be entitled to receive an amount in cash, without interest, rounded down to the nearest cent, equal to the product of (a) the amount of the fractional share interest in a share of Parent Common Stock to which such holder would, but for this Section 5.5, be entitled under Section 4.1 and (b) an amount equal to the average of the volume-weighted average price per share of Parent Common Stock on the New York Stock Exchange as reported by Bloomberg L.P., or, if not reported therein, in another authoritative source mutually selected by Parent and the Partnership on the Trading Day immediately prior to the Effective Time for ten Trading Days ending on the fifth full Business Day immediately prior to the Closing Date. No holder of Eligible Units shall be entitled by virtue of the right to receive cash in lieu of fractional shares of Parent Common Stock described in this Section 5.5 to any dividends, distributions, voting rights or any other rights in respect of any fractional share of Parent Common Stock. The payment of cash in lieu of fractional shares of Parent Common Stock is not a separately bargained-for consideration but merely represents a mechanical rounding-off of the fractions in the exchange.

-17-

5.6 Termination of Exchange Fund . Any portion of the Exchange Fund (including the proceeds of any investments of the Exchange Fund and any shares of Parent Common Stock) that remains unclaimed as of the date that is twelve months following the Effective Time shall be delivered to Parent. Any holder of Eligible Units who has not theretofore complied with this ARTICLE V shall thereafter look only to Parent for delivery of the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, that such holder has the right to receive pursuant to this ARTICLE V, in each case, without any interest thereon. Notwithstanding the foregoing, none of the Surviving Entity, Parent, the Exchange Agent or any other Person shall be liable to any former holder of Common Units for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any portion of the Exchange Fund which remains undistributed to the holders of Eligible Units immediately prior to the time at which the Exchange Fund would otherwise escheat to, or become property of, any Governmental Entity, shall, to the extent permitted by Laws, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

5.7 Lost, Stolen or Destroyed Certificates . In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and the posting by such Person of a bond in customary amount and upon such terms as may be required as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, payable or issuable pursuant to this ARTICLE V, had such lost, stolen or destroyed Certificate been surrendered.

5.8 Withholding Rights . Each of Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent and the Surviving Entity shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, without duplication, such amounts, which may include shares of Parent Common Stock, as Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent and the Surviving Entity reasonably deem to be required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld by Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent or the Surviving Entity, as applicable, such withheld amounts (a) shall be timely remitted by Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent or the Surviving Entity, as applicable, to the applicable Governmental Entity, and (b) to the extent such withheld amounts are remitted to the appropriate Governmental Entity, shall be treated for all purposes of this Agreement as having been paid to the holder of Common Units in respect of which such deduction and withholding was made by Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent or the Surviving Entity, as applicable. If withholding is taken in shares of Parent Common Stock, Parent, SETLLC, Merger Sub, the Partnership, the Surviving Entity and the Exchange Agent, as applicable, shall be treated as having sold such consideration for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate Governmental Entity.

Nothing in this Section 5.9 shall be construed to permit the Parties to take any action except to the extent consistent with, and not otherwise prohibited by, the terms of this Agreement.
