As used in this Agreement, “Extraordinary Receipt” means any cash received by or paid to any Person as a result of proceeds of insurance (other than proceeds of business interruption insurance to the extent such proceeds constitute compensation for lost earnings) and condemnation awards (and payments in lieu thereof); provided, however, that an Extraordinary Receipt shall not include cash receipts from proceeds of insurance or condemnation awards (or payments in lieu thereof) to the extent that such proceeds or awards are received by any Person in respect of any third party claim against, or liability of, such Person and applied to pay (or to reimburse such Person for its prior payment of) such claim or liability and the costs and expenses of such Person with respect thereto.

If on or before the date that is six months after the Joinder Agreement No. 1 Effective Date, there occurs any (i) prepayment or repayment of Series A Incremental Term Loans with the proceeds of, or any conversion of such Series A Incremental Term Loans into, any new debt financing or any replacement debt financing, in either case, bearing interest at an “effective” interest rate less than the “effective” interest rate applicable to the Series A Incremental Term Loans (as such comparative rates are determined by the Administrative Agent) or (ii) amendment to the terms of the Series A Incremental Term Loans that, directly or indirectly, reduces the “effective” interest rate applicable to the Series A Incremental Term Loans (in each case, with original issue discount and upfront fees, which shall be deemed to constitute like amounts of original issue discount, being equated to interest margins in a manner consistent with generally accepted financial practice based on an assumed four-year life to maturity) (any such transaction or event described in (i) or (ii) above, a “Repricing Event”), then, simultaneously with the consummation of such Repricing Event, the Borrower shall pay to each Series A Incremental Term Loan Lender that refuses to consent to such amendment (which shall include each Series A Incremental Term Loan Lender that refuses to consent to an amendment if such Series A Incremental Term Loan Lender is required to make a mandatory assignment pursuant to Section 10.13 of the Credit Agreement in connection therewith) a fee (the “Repricing Fee”) in an amount equal to 1.00% of the aggregate principal amount of the Series A Incremental Term Loans so repriced or refinanced in such Repricing Event (such Repricing Fee to be allocated among the Series A Incremental Term Loan Lenders pro rata in accordance with the aggregate amount of Series A Incremental Term Loans of each such Series A Incremental Term Loan Lender so repriced or refinanced).

(ii) provide evidence reasonably satisfactory to the Administrative Agent that counterparts of the Modifications are in form suitable for filing or recording in all filing or recording offices that the Administrative Agent may deem reasonably necessary in order to maintain a valid first and subsisting Lien on the property described therein subject to Permitted Prior Liens in favor of the Administrative Agent for the benefit of the Secured Parties and evidence that all filing, documentary, stamp, intangible and recording taxes and fees will be paid upon the recording of the Modifications; and

(iii) cause to be provided to the Administrative Agent fully paid endorsement(s) to the existing Mortgage Policies reasonably satisfactory the Administrative Agent or other evidence reasonably satisfactory to the Administrative Agent insuring that the priority of the Lien of such Mortgages has not changed and confirming and/or insuring that since the issuance of the existing title insurance policy there has been no change in the condition of title and there are no intervening liens or encumbrances that may then or thereafter take priority over the Lien of such Mortgages (other than Permitted Prior Liens).

(a)     each Loan Party has all requisite power and authority to execute, deliver and perform this Agreement and to carry out the transactions contemplated by, and perform its obligations under, this Agreement and, with respect to the Borrower, the Credit Agreement;

(c)    no material approval, consent, exemption, authorization, or other action by, or notice to, or filing with, any Governmental Authority or any other Person is necessary or required in connection with the execution, delivery or performance by, or enforcement against, any Loan Party of this Agreement or with respect to the Borrower, the Credit Agreement, except for the approvals, consents, exemptions, authorizations, actions, notices and filings which have been duly obtained, taken, given or made and are in full force and effect;

(d)    this Agreement has been duly executed and delivered by each Loan Party that is a party hereto. Each of this Agreement and the Credit Agreement constitutes a legal, valid and binding obligation of each Loan Party to the extent it is a part thereto, enforceable against each Loan Party in accordance with its terms, except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws generally affecting creditors’ rights and by equitable principles (regardless of whether enforcement is sought in equity or at law);

(e)    the representations and warranties contained in Article 5 of the Credit Agreement or any other Loan Document shall be true and correct in all material respects as of the Joinder Agreement No. 1 Effective Date to the same extent as though made as of that date, except to the extent such representations and warranties specifically relate to an earlier date, in which case they shall be true and correct in all material respects as of such earlier date; provided that any representation and warranty that is qualified as to “materiality”, “Material Adverse Effect” or similar language shall be true and correct (after giving effect to any qualification therein) in all respects; and

(f)    no Event of Default or Default has occurred and is continuing, in each case immediately before and immediately after giving effect to this Agreement and the transactions contemplated hereby.

The Borrower and each Guarantor acknowledges and agrees that each Loan Document to which it is a party or otherwise bound shall continue in full force and effect and that all of its obligations thereunder shall be valid and enforceable and shall not be impaired or limited by the execution or effectiveness of this Agreement or the First Joinder Agreement.
