In the event that such payment is not made Lender, at its sole discretion, may proceed to file suit against Indemnitor to compel such payment. In addition to any remedy available for failure to periodically pay such amounts, such amounts shall thereafter bear interest at the “Default Rate” as set forth in the Note.

3

Indemnitor waives any right to require that any action be brought against Borrower or any other person or that any other remedy under the Note or Mortgage be exhausted. Lender may, at its option, proceed against Indemnitor in the first instance to collect monies where due or obtain performance under this Agreement, without first proceeding against Indemnitor or any other person and without first resorting to the Note and Mortgage or any other remedy under the Note and Mortgage.

4. Duration of Indemnity. This Agreement shall pertain to a period of time commencing on the date hereof and shall apply to any claim, demand or charge contemplated by this Agreement made or asserted at any time. This Agreement shall not be limited to any extent by the term of the Loan and shall continue, survive and remain in full force and effect notwithstanding foreclosure under the Mortgage or delivery of a deed in lieu of foreclosure. The provisions of this Agreement shall be deemed to survive issuance of a certificate of title and shall continue in full force and effect after any foreclosure or other proceeding by which Lender, its successors and assigns, succeed to ownership of the Property; provided, however, that the indemnity obligations under this Agreement shall apply only to conditions on the Property existing prior to the date of Lender’s ownership of the Property. This Agreement and the indemnity obligations hereunder shall terminate upon payment in full and satisfaction of the Note and Mortgage.

5. Notices from Indemnitor. Indemnitor shall immediately advise Lender in writing of (i) any governmental or regulatory actions instituted or threatened under any Hazardous Material Law affecting the Property or the matters indemnified hereunder including, without limitation, any notice of inspection, abatement or noncompliance, (ii) all claims made or threatened by any third party against Indemnitor or the Property relating to damage, contribution, cost recovery, compensation, loss or injury resulting from any Hazardous Material, (iii) Indemnitor’s discovery of any occurrence or condition on any real property adjoining or in the vicinity of the Property that could cause the Property to be classified in a manner which may support a claim under any Hazardous Material Law, and (iv) Indemnitor’s discovery of any occurrence or condition on the Property or any real property adjoining or in the vicinity of the Property which could subject Indemnitor or the Property to any restrictions on ownership, occupancy, transferability or use of the Property under any Hazardous Material Law. Indemnitor shall immediately deliver to Lender any documentation or records as Lender may request in connection with all such notices, inquiries, and communications above and shall advise Lender of any subsequent developments.

6. Notice of Claims Against Lender. Lender shall give written notice to Indemnitor of any action against Lender which might give rise to a claim by Lender against Indemnitor under this Agreement. If any action is brought against Lender, Indemnitor, at Lender’s sole option and Indemnitor’s expense, may be required to defend against such action with counsel satisfactory to Lender and, with Lender’s sole consent and approval, to settle and compromise any such action. However, Lender may elect to be represented by separate counsel, at Lender’s expense, and if Lender so elects any settlement or compromise shall be effected only with the consent of Lender. Lender may elect to join and participate in any settlements, remedial actions, legal proceedings or other actions included in connection with any claims under this Agreement.

4

7. Payment of Lender’s Expenses. If Lender retains counsel for advice or other representation (i) with respect to this Agreement, (ii) in any litigation, contest, dispute, suit or proceeding (whether instituted by Lender, Indemnitor, or any other party) in any way relating to this Agreement and the indemnities described herein, or (iii) to enforce Indemnitor’s obligations hereunder, then all of the reasonable attorneys’ fees arising from such services and all related expenses and court costs shall be payable on demand by Indemnitor to Lender.

8. Waivers. Indemnitor hereby waives notice of: (a) Lender’s acceptance of this Agreement; (b) any Indemnitor’s grant to Lender of a security interest, lien or encumbrance in any of Indemnitor’s assets; (c) Lender’s release, waiver or modification of this Agreement or any Indemnitor’s obligations hereunder, or any other party’s guaranty of the Note or any security interest, lien or encumbrance in any other party’s assets given to Lender to secure the Note, this Agreement or any other party’s guaranty; (d) Lender’s amendment of the Note or any other agreement or instrument referred to therein; (f) extensions of time of payment of the Note granted to Indemnitor; and (g) acceptance from Indemnitor (or any other party) of any partial payment or payments on the Note or any collateral securing the payment thereof or the settlement, subordination, discharge or release of the Note. Indemnitor agrees that Lender may have or at any time may do any or all of the foregoing actions in such manner, upon such terms and at such times as Lender, in its sole discretion, deems advisable, without in any way impairing, affecting, reducing or releasing Indemnitor from their obligations under this Agreement, and Indemnitor hereby consents to each of the foregoing actions. To the extent permitted by law, Indemnitor further waives any right to assert against Lender any legal or equitable defense, counterclaim, set off or cross claim which any of them may now or at any time or times hereafter have against each other.

9. No Waiver. Indemnitor’s obligations hereunder shall in no way be impaired, reduced or released by reason of (a) Lender’s omission or delay to exercise any right described herein; or (b) any act or omission of Lender in connection with any notice, demand, warning or claim regarding violations of codes, laws or ordinances governing the Property.

10. Joint and Several Liability; Separate Obligation. The obligations of each Indemnitor are joint and several from each other Indemnitor. Borrower and Guarantor agree that the obligations, covenants and indemnification provided in this Agreement are separate, independent of and in addition to Borrower’s undertakings under the Note. Borrower and Guarantor agree that a separate action may be brought to enforce the provisions of this Agreement which shall in no way be deemed to be an action on the Note, whether or not Lender would be entitled to a deficiency judgment following a judicial foreclosure sale under the Mortgage.

11. Successors and Assigns. This Agreement and the indemnities contained in this Agreement shall be continuing, irrevocable and binding on Indemnitor and its respective successors and assigns, and shall inure to the benefit of Lender and Lender’s successors and assigns. The death or dissolution of any Indemnitor shall not affect this Agreement or any of the other Indemnitor’s obligations hereunder. The respective liabilities of any Indemnitor hereunder are not contingent on the signature of any other Indemnitor.

5

12. Survival of Representations and Warranties. All representations and warranties of Indemnitor contained in the Agreement shall survive the execution and delivery of this Agreement.

13. Notices. Any notices which any party may be required, or may desire, to give shall, unless otherwise specified, be in writing and shall be (i) hand delivered, effective upon receipt (ii) sent by United States Express Mail or by private overnight courier, effective upon receipt, or (iii) served by certified mail, postage prepaid, return receipt requested and addressed as follows:
