The prepayment shall be made on the Proposed Prepayment Date. The principal amount of any Note prepaid pursuant to this paragraph 4F shall be applied and reduce the required prepayments of such Note referred to in paragraph 4A hereof in the inverse order of their scheduled due dates.

(vi) Officer’s Certificate. Each offer to prepay the Notes pursuant to this paragraph 4F shall be accompanied by a certificate, executed by a Responsible Officer of the Company and dated the date of such offer, specifying (i) the Proposed Prepayment Date, (ii) the date that such offer is made pursuant to this xxxxxxxxx 0X, (xxx) the principal amount of each Note offered to be prepaid, (iv) the interest and the Yield-Maintenance Amount, if any, that would be due on each Note offered to be prepaid, (v) that the conditions of this paragraph 4F have been fulfilled, and (vi) in reasonable detail, a description of the event giving rise to such offer to prepay and the details of the calculation of the amount of the Notes offered to be prepaid.

5M. Environmental Remediation and Indemnification. If at any time any Hazardous Material is discovered on, under or about any Mortgaged Property or any other property owned or operated by the Company or any Subsidiary (“Other Property”) and failure to remediate the same would cause the Company or any Subsidiary to be in violation of any Environmental Law that could reasonably be expected to have a Material Adverse Effect, the Company will inform the Holders of the same and of the Company’s proposed remediation program, and the Company or such Subsidiary will, at no cost and expense to the Collateral Agent or the Holders, and only to the extent of any legal requirement under applicable Environmental Laws for the Company or such Subsidiary to do so, remediate or remove such Hazardous Materials from such Mortgaged Property or Other Property or the groundwater underlying such Mortgaged Property or Other Property in accordance with (i) such remediation program as a prudent operator would undertake, (ii) the approval of the appropriate Governmental Persons, if any such approval is required under the applicable Environmental Laws, and (iii) all applicable Environmental Laws the noncompliance with which could reasonably be expected to have a Material Adverse Effect.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, the Designated Spread over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City local time) on the Business Day next preceding the Settlement Date with respect to such Called Principal on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields shall have been so reported as of the Business Day next preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

11S. Maximum Interest Payable. The Company, each Purchaser and any other Holders specifically intend and agree to limit contractually the amount of interest payable under this Agreement, the Notes, the other Loan Documents and all other instruments and agreements related hereto and thereto to the maximum amount of interest lawfully permitted to be charged under applicable law.

If any amount of interest taken or received by any Purchaser or any Holder shall be in excess of said maximum amount of interest which, under applicable law, could lawfully have been collected by such Purchaser or such Holder incident to such transactions, then such excess shall be deemed to have been the result of a mathematical error by all parties hereto and shall be refunded promptly by the Person receiving such amount to the party paying such amount, or, at the option of the recipient, credited ratably against the unpaid principal amount of the Note or Notes held by such Purchaser or such Holder, respectively. All amounts paid or agreed to be paid in connection with such transactions which would under applicable law be deemed “interest” shall, to the extent permitted by such applicable law, be amortized, prorated, allocated and spread throughout the stated term of this Agreement and the Notes. “Applicable law” as used in this paragraph means that law in effect from time to time which permits the charging and collection of the highest permissible lawful, nonusurious rate of interest on the transactions herein contemplated, and “maximum rate” as used in this paragraph means, with respect to each of the Notes, the

maximum lawful, nonusurious rates of interest (if any) which under applicable law may be charged to the Company from time to time with respect to such Notes.
