Section 15.  Definitions.  All capitalized terms not otherwise defined herein are used herein with the respective definitions given them in the Credit Agreement, as amended by this Amendment.

Section 16.  Funding into Escrow.

(a)           Generally.  No later than 2:00 p.m. on the date one day prior to the anticipated closing date of the Acquisition and upon the Agent’s request, each Lender will make available to the Agent at the Principal Office, in immediately available funds, the proceeds of such Lender’s Revolving Loan that the Borrower has requested be made by such Lender on the closing date of the Acquisition.  No later than 4:00 p.m. on such date, the Agent shall deliver the proceeds of such Revolving Loans to a title company or financial institution (the “Escrow Agent”) which shall have agreed (a) to hold the proceeds of such Revolving Loans in escrow for the Lenders on terms acceptable to the Agent in its sole discretion and (b) to release such proceeds to the Borrower only upon written confirmation (which may be in the form of an e-mail) from the Agent or the Agent’s counsel that all of the conditions precedent set forth in Section 2 of this

13

Amendment and the applicable conditions contained in Article V. of the Credit Agreement shall have been satisfied or waived by the Lenders.  Unless the Agent shall have been notified by any Lender that such Lender does not intend to make available to the Agent the proceeds of the Revolving Loan to be made by such Lender on the closing date of the Acquisition, the Agent may assume that such Lender will make the proceeds of such Revolving Loan available to the Agent and the Agent may (but shall not be obligated to), in reliance upon such assumption, make available to the Escrow Agent the amount of such Revolving Loan to be provided by such Lender. Subject to satisfaction (or waiver by the Lenders) of the conditions set forth in Section 2 of this Amendment and the applicable conditions contained in Article V. of the Credit Agreement, the Agent will make the proceeds of all such Revolving Loans available to the Borrower no later than 10:00 a.m. on the closing date of the Acquisition by authorizing the Escrow Agent to release such proceeds from such escrow.

(b)           Interest Accrual; Return of Funds from Escrow.  The Borrower acknowledges that interest shall begin to accrue on a Lender’s Revolving Loan being made as contemplated in the preceding subsection on the date such Lender makes the proceeds of such Revolving Loan available to the Agent (or the Agent makes the proceeds of a Revolving Loan available to the Escrow Agent on behalf of a Lender, with such interest being for the account of the Agent) as contemplated in the immediately preceding subsection.  The Borrower agrees that if the closing date of the Acquisition has not occurred by January 31, 2007: (i) the Agent, on behalf of the Lenders, may require the Escrow Agent to return to the Agent the proceeds of such Revolving Loans which shall be paid to the Lenders (or the Agent, if applicable) in accordance with the applicable provisions of the Credit Agreement; (ii) the Borrower shall pay to the Agent all accrued and unpaid interest on such Revolving Loans, which shall be paid to the Lenders (or the Agent, if applicable) in accordance with the applicable provisions of the Credit Agreement and (iii) the amendments to the Credit Agreement contemplated by Section 1 shall be of no effect.

Section 17.  No Tax Advice.  The Borrower acknowledges and agrees that it has not relied on the Agent, any Lender or any of their respective legal counsel for any tax advice relating to the transaction contemplated by this Amendment and the other Loan Documents.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties hereto, the parties hereto hereby agree as follows:

Section 1.  Specific Amendments to Guaranty.  The parties hereto agree that the Guaranty is amended as follows:

(a)           the Guaranty is amended by amending and restating Section 1 thereof in its entirety as follows:

Section 1.  Guaranty.  Subject to Section 30 in the case of a Reckson Subsidiary, each Guarantor hereby absolutely, irrevocably and unconditionally guaranties the due and punctual payment and performance when due, whether at stated maturity, by acceleration or otherwise, of all of the following (collectively referred to as the “Guarantied Obligations”): (a) all indebtedness and obligations owing by the Borrower to any Lender or the Agent under or in connection with the Credit Agreement and any other Loan Document, including without limitation, the repayment of all principal of the Loans and the Reimbursement Obligations, and the payment of all interest, fees, charges, attorneys’ fees and other amounts payable to any Lender or the Agent thereunder or in connection therewith; (b) any and all extensions, renewals, modifications, amendments or substitutions of the foregoing; (c) all expenses, including, without limitation, reasonable attorneys’ fees and disbursements, that are incurred by the Lenders and the Agent in the

(b)  the Guaranty is further amended by inserting the following Section 30 therein as follows:

Section 30.  Limitation of Liability of Reckson Subsidiaries.

(a)           Generally.  Notwithstanding anything to the contrary contained in this Guaranty but subject to the immediately following sentence, until the occurrence of the Reckson Limitation Termination Event the amount of Guarantied Obligations recoverable from the Reckson Subsidiaries that are Guarantors shall not exceed the Allocable Guaranty Limitation.  Upon the occurrence of the Reckson Limitation Termination Event and at all times thereafter, the limitations of the immediately preceding sentence shall cease to apply and shall be of no further force or effect.

“Pari Passu Indebtedness” means Indebtedness (i) owing by the Borrower; (ii) evidenced by documents, instruments and agreements containing terms, conditions, representations, covenants and events of default substantially the same as, or less restrictive than, but in no event more restrictive than, those contained in the Credit Agreement and the other Loan Documents; (iii) that is not Secured Indebtedness; (iv) that ranks pari passu with the Indebtedness owing under the Credit Agreement; and (v) that has been Guarantied by each Reckson Party that is a Guarantor hereunder on terms substantially the same as the terms of this

A-2
