The foregoing documents, are collectively referred to as the “Loan Documents.” As used herein, the term “Assuming Obligors” shall mean Assuming Borrower and Assuming Indemnitor, and the term “Original Obligors” shall mean Original Borrower and Original Indemnitor.

Assuming Borrower agrees to pay when and as due all sums due under the Note and agrees to pay, perform and discharge each and every other obligation of payment and performance of the “Borrower” or “Assignor” pursuant to and as set forth in the Loan Documents at the time, in the manner and otherwise in all respects as therein provided. Assuming Borrower hereby acknowledges, agrees and warrants that to its knowledge: (i) there are no rights of set-off or counterclaim, nor any defenses of any kind, whether legal, equitable or otherwise, which would enable Assuming Borrower to avoid or delay timely performance of its obligations under the Loan Documents, as applicable; and (ii) there are no monetary encumbrances or liens of any kind or nature against the Property except those created by the Loan Documents, and all rights, priorities, titles, liens and equities securing the payment of the Note are expressly recognized as valid and are in all things renewed, continued and preserved in force to secure payment of the Note, except as amended herein.

Assuming Indemnitor shall be liable and responsible for each and all of the liabilities of the Indemnitor thereunder, and shall be substituted in lieu of and in place of Original Indemnitor as fully and completely as if Assuming Indemnitor had originally executed and delivered such Loan Documents as the Indemnitor thereunder including, without limitation, all of those obligations, agreements and liabilities which would have, but for the provisions of this Agreement, been the obligations, agreements and liabilities of Original Indemnitor, without regard to when such obligations, agreements and liabilities arise, accrue or have arisen or accrued, and without regard to the Indemnitor then responsible or liable therefor at the time of such accrual. From and after the date hereof, Assuming Indemnitor further agrees to abide by and be bound by all of the terms of the Loan Documents having reference to the Indemnitor, all as though each of the Loan Documents to which Original Indemnitor is a party had been made, executed and delivered by Assuming Indemnitor as the Indemnitor. From and after the date hereof, Assuming Indemnitor hereby agrees to pay, perform and discharge each and every obligation of payment and performance of the Indemnitor under, pursuant to and as set forth in the Loan Documents at the time, in the manner and otherwise in all respects as therein provided. With respect to the Environmental Indemnity Agreement, the liability of Assuming Indemnitor shall be joint and several with that of Assuming Borrower.

5. Notices to Indemnitor. Without amending, modifying or otherwise affecting the provisions of the Loan Documents except as expressly set forth herein, Lender shall, from and after the date of this Agreement, deliver any notices to the Indemnitor which are required to be delivered pursuant to the Loan Documents or are otherwise delivered by Lender thereunder at Lender’s sole discretion, to Assuming Indemnitor’s address set forth above.

Original Obligors are hereby released from any liability to Lender under any and all of the Loan Documents first arising or accruing subsequent to the Assumption. Lender’s consent to such transfer and Assumption shall, however, not constitute its consent to any subsequent transfers of the Property. Original Obligors hereby acknowledge and agree that the foregoing release shall not be construed to release Original Obligors from any personal liability under the Note or any of the other Loan Documents for any act or event occurring or obligation arising prior to or simultaneously with the closing of the transaction described herein.

Lender hereby represents and warrants to Assuming Obligors and Original Obligors that, to the “actual knowledge of Lender”: (i) as of the date hereof, no default or Event of Default under the Loan Documents has occurred and is continuing, and (ii) no facts or circumstances exist which through the passage of time, would constitute an Event of Default. For purposes of this paragraph, the “actual knowledge of Lender” shall mean the actual knowledge of employees of Wachovia Bank National Association (“Wachovia”) actively involved with the transactions described herein or with the servicing of the Loan without any independent inquiry or investigation. The “actual knowledge of Lender” shall not include knowledge imputed from other Lender Parties or other groups or employees of Wachovia not actively involved in the servicing of the Loan.

Original Obligors and Assuming Obligors, on behalf of themselves and their heirs, successors and assigns, covenant and agree never to institute or cause to be instituted or continue prosecution of any suit or other form of action or proceeding of any kind or nature whatsoever against any of Lender Parties by reason of or in connection with any of the foregoing matters, claims or causes of action. Notwithstanding anything to the contrary herein, this Section 7 shall only apply to the Assuming Obligors with respect to (and accordingly, the release and discharge of Lender Parties by Assuming Obligors shall only be effective with respect to) Actions which arose prior to the date hereof, and Assuming Obligors shall retain all rights and remedies against the Lender Parties with respect to any Actions arising from and after the date hereof.

Original Borrower covenant and agree that Lender Parties have no further duty or obligation of any nature to Original Borrower relating to such escrow and reserve balances. Original Borrower hereby release and forever discharge Lender Parties from any obligations to Original Borrower relating to such escrow and reserve balances.
