due to the action or inaction of any Tenant (that is not an Affiliate of Indemnitor), Indemnitor shall be deemed not to have breached such covenants provided that Indemnitor promptly takes all commercially reasonable actions necessary to effectuate remediation of such breach.

3. Indemnified Rights/Cooperation and Access. In the event the Indemnified Parties have a reasonable belief that Hazardous Substances exist on the Property that do not, in the reasonable discretion of the Indemnified Parties, (a) endanger any tenants or other occupants of the Property or their guests or the general public, or (b) materially and adversely affect the value of the Property, upon reasonable notice from Indemnitee containing a description of the Hazardous Substances, Indemnitor shall, at Indemnitor’s sole cost and expense, promptly cause an engineer or consultant selected by Indemnitor and reasonably satisfactory to the Indemnified Parties to conduct any environmental assessment or audit of the Hazardous Substances (the scope of which shall be determined in the reasonable discretion of the Indemnified Parties) and take any samples of soil, groundwater or other water, air or building materials or other invasive testing that is, in each case, reasonably requested by Indemnitee and related to the Hazardous Substances, and promptly deliver to Indemnitee the results of any such assessment, audit, sampling or other testing; provided, however, if such results are not delivered to Indemnitee within a reasonable period or if the Indemnified Parties has a reasonable belief that Hazardous Substances exist on the Property that, in the reasonable judgment of the Indemnified Parties, endanger any tenant or other occupant of the Property or their guests or the general public or may imminently materially and adversely affect the value of the Property, upon reasonable written notice to Indemnitor, the Indemnified Parties and any other Person designated by the Indemnified Parties, including, but not limited to, any receiver and/or any environmental consultant, shall have the right, but not the obligation, to enter upon the Property following written notice at all reasonable times (subject to the rights of Tenants under their Leases and in a manner that does not unreasonably interfere with the use or operation of the Property) to assess any and all aspects of the environmental condition of the Property and its use, including, but not limited to, conducting any environmental assessment or audit of the condition (the scope of which shall be determined in the reasonable discretion of the Indemnified Parties) and taking samples of soil, groundwater or other water, air or building materials related to the condition and reasonably conducting other invasive testing related to the condition. Indemnitor shall cooperate with and provide the Indemnified Parties and any such Person designated by the Indemnified Parties with access to the Property. Notwithstanding the foregoing, no entry shall be made by the Indemnified Parties or any Person designated by the Indemnified Parties so long as Indemnitor conducts appropriate environmental assessments of the Property and promptly and diligently takes such further action as is reasonably required to cure or mitigate any Release of any Hazardous Substances.

4. Indemnification. Indemnitor covenants and agrees, at its sole cost and expense, to protect, defend, indemnify, release and hold Indemnified Parties harmless from and against any and all Losses (defined below) imposed upon, or incurred by, or asserted against, any Indemnified Parties and directly or indirectly arising out of or in any way relating to any one or more of the following: (a) any unlawful or unpermitted presence of any Hazardous Substances in, on, above or under the Property; (b) any past, present or threatened Release of Hazardous Substances in, on, above, under or from the Property; (c) any activity by any of Indemnitor, any Person affiliated with Indemnitor and/or any tenant or other user of the Property (other than the Indemnified Parties) in connection with any actual, proposed or threatened use, treatment,

Notwithstanding any other provision of this Agreement or any of the other Loan Documents, in no event shall Indemnitor be required to indemnify any Indemnified Party for (i) such Indemnified Party’s or any other Indemnified Party’s gross negligence or willful misconduct or (ii) the presence of Hazardous Materials on, in, under, about or from any Property which are Released during the time that any Indemnified Party or their respective successors or assigns (including a purchaser at a foreclosure sale), or their respective agents, takes possession of the Property (by foreclosure of the Mortgage or deed-in-lieu thereof). In addition, in no event shall Indemnitor have any liability hereunder (A) with respect to any specific acts taken by any receiver, conservator, trustee, or liquidator that is appointed by or on behalf of any Indemnified Party and is not caused by any Affiliate of Indemnitor; or (B) for the presence of Hazardous Materials on, in, under, about or from any Property which are Released after the date of a Transfer and Assumption, provided that, in connection with such Transfer and Assumption, a Replacement Guarantor provides a replacement environmental indemnity with respect to Releases occurring after the date of such Transfer and Assumption, in accordance with the Loan Agreement.

5. Right to Contest.

(a) After prior written notice to Indemnitee, Indemnitor may, at its sole cost and expense, contest any Environmental Liens or Environmental Laws, or perform any Remediation, provided that all of the following conditions are continuously satisfied at all times during the course of any such contest or Remediation:

(i) no Event of Default (other than as related to the Hazardous Substances involved in such contest or Remediation) exists and is continuing under any of the Loan Documents;

(ii) such proceeding shall be permitted under and be conducted in accordance with all applicable statutes, laws and ordinances;

(iii) neither the Property nor any part thereof or interest therein will be in reasonable danger of being sold, forfeited, terminated, canceled or lost;

(iv) Indemnitee (and Indemnitee’s agents, officers, directors, servants, employees, contractors and shareholders) shall not be subject to any criminal or other penalties, fines, costs or expenses, by reason of such contest or Remediation or any delays in connection therewith, for which they are not indemnified by Indemnitor;

(v) only if collateral is not required to be posted in connection with such proceeding, in the case of Liens in excess of the Contest Threshold (as defined in the Loan Agreement), to insure the payment of such Environmental Liens during the term of such contest, Borrower shall deliver to Lender either (A) cash, cash equivalents, a Letter of Credit, a guaranty from a Qualified Guarantor or other security as may be reasonably approved by Lender, in an amount equal to one hundred ten percent (110%) of the contested amount over the Contest Threshold or (B) a payment and performance bond in an amount equal to one hundred percent (100%) of the contested amount over the Contest Threshold from a surety acceptable to Lender in its reasonable discretion;

(vi) such contest shall not be reasonably likely to result in a Material Adverse Effect; and

(vii) a contest shall be diligently prosecuted until a final judgment is obtained or final settlement or release is affected.

(b) After ten (10) Business Days’ notice to Borrower, Lender may pay over any such cash or other security held by Lender to the claimant entitled thereto at any time when, in the reasonable judgment of Lender, the entitlement of such claimant is established by the Governmental Authority authorized to make such determination or the Property (or any part thereof or interest therein) shall be in immediate danger of being sold, forfeited, terminated, cancelled or lost or there shall be any immediate danger of the Lien of the Mortgage being primed by any related Environmental Lien.

(c) Unless a contest has been instituted as permitted hereunder with respect to any Remediation, Indemnitor shall commence the Remediation in accordance with Environmental Laws. In any event, except in the case of an emergency, at least fifteen (15) Business Days prior to commencement of such Remediation, Indemnitor shall submit to Indemnitee reasonably detailed plans for such Remediation complying with Environmental Laws.

(d) If a contest has been instituted as permitted hereunder, Remediation shall be instituted promptly following an unsuccessful nonappealable completion of any contest and shall be diligently prosecuted until the Hazardous Substances involved in the contest are removed, relocated, encapsulated or disposed of as required by the Environmental Laws.

(e) Indemnitor shall notify Indemnitee within ten (10) days after commencement of such contest or Remediation and shall render to Indemnitee a written monthly report detailing the progress thereof including such information as Indemnitee shall reasonably request.

(f) So long as all of such conditions are continuously satisfied, Indemnitor may proceed with such contest; provided, however, Indemnitor shall not enter into any settlement agreement binding upon Indemnitee without its prior consent, which consent shall not be unreasonably withheld, conditioned or delayed. Any such settlement effected without Indemnitee’s prior consent shall not be binding on Indemnitee.

6. Duty to Defend and Attorneys’ and Other Fees and Expenses. Upon written request by any Indemnified Party, Indemnitor shall defend such Indemnified Party(ies) against any claim for which indemnification is required hereunder (if requested by any Indemnified Party, in the name of the Indemnified Party), by attorneys and other professionals reasonably approved by the Indemnified Parties. Indemnitor shall have the right to negotiate and enter into and/or consent to any settlement, subject to the prior approval of the Indemnified Party, which approval shall not be unreasonably withheld, conditioned or delayed, provided that such approval is not required in connection with any settlement which includes any unconditional release of the Indemnified Party involved in such action and all related actions for all liability for which such parties are seeking indemnification and there is no admission of wrongdoing on the part of the Indemnified Party. Notwithstanding the foregoing, any Indemnified Party may engage their own attorneys and other professionals to defend or assist them in the event any such Indemnified Party reasonably determines that the defense as conducted by Indemnitor is not proceeding or being conducted in a satisfactory manner, that there are any legal defenses available to it that are not being addressed or that a conflict of interest exists between any of the parties represented by Indemnitor’ s counsel in such action or proceeding, and, at the option of Indemnified Party, their attorneys shall thereafter control the resolution of such claim or proceeding; provided, however, (x) that so long as no Event of Default exists and is continuing, Indemnified Party shall first provide Indemnitor with fifteen (15) Business Days’ prior written notice of any determination pursuant to this Paragraph 6 (unless any Indemnified Party determines, in its sole discretion, that its interest may be adversely affected prior to the expiration of such notice period, in which case, Indemnified Party may take immediate action and send written notice to Indemnitor thereafter); and (y) Indemnified Party shall not enter into any settlement of such a proceeding without the consent of Indemnitor, which consent shall not be unreasonably withheld. Any Indemnified

Party shall have the right to negotiate and enter into and/or consent to any settlement, subject to the prior approval of Indemnitor, which approval shall not be unreasonably withheld, conditioned or delayed.

This Agreement is not collateral or security for the Obligations of Borrower pursuant to the Loan Agreement, unless Indemnitee expressly elects in writing to make this Agreement additional collateral or security for such Obligations of Borrower pursuant to the Loan Agreement, which Indemnitee is entitled to do in its sole and absolute discretion. It is not necessary for an Event of Default to have occurred pursuant to and as defined in the Mortgage or the Loan Agreement for Indemnified Parties to exercise their rights pursuant to this Agreement. Notwithstanding any provision of the Loan Agreement to the contrary, the obligations of Indemnitor pursuant to this Agreement are exceptions to any non-recourse or exculpation provision of the Loan Agreement; and Indemnitor expressly acknowledges and agrees that it is fully and personally liable for such obligations, and such liability is not limited to the original or amortized principal balance of the Loan or the value of the Property.
