(A) each Person with a 2014 February Replacement Term A-2 Loan Commitment (as defined below), in excess of any 2014 February Replacement Term A-2 Loan Conversion Amount (as defined below) of such Person (each such commitment, a “New 2014 February Replacement Term A-2 Loan Commitment” and each such Person, a “New 2014 February Replacement Term A-2 Lender” and, together with the 2014 February Converting Term A-2 Lenders and the Designated 2014 February Replacement Term A-2 Lender, collectively the “2014 February Replacement Term A-2 Lenders”) severally agrees to make and fund to the Designated Borrower a new loan (each, a “New 2014 February Replacement Term A-2 Loan”, together with the Converted 2014 February Replacement Term A-2 Loans (as defined below), collectively, the “2014 February Replacement Term A-2 Loans”) in Dollars in a principal amount equal to such New 2014 February Replacement Term A-2 Lender’s New 2014 February Replacement Term A-2 Loan Commitment on the Sixth Amendment Effective Date and (B) each 2014 February Converting Term A-2 Lender severally agrees to convert its existing Refinanced Term A-2 Loans into 2014 February Replacement Term A-2 Loans on the Sixth Amendment Effective Date in a principal amount equal to such 2014 February Converting Term A-2 Lender’s 2014 February Replacement Term A-2 Loan Conversion Amount, to refinance all outstanding Refinanced Term A-2 Loans in accordance with Section 11.01 of the Credit Agreement and this Sixth Amendment.

It is understood and agreed that the 2014 February Replacement Term A-2 Loans being made pursuant to this Sixth Amendment shall constitute “Replacement Term Loans” as defined in, and pursuant to, Section 11.01 of the Credit Agreement and the Refinanced Term A-2 Loans being refinanced shall constitute “Refinanced Term Loans” as defined in, and pursuant to, such Section 11.01.

(ii) DBSI has prepared a schedule (the “2014 February Replacement Term A-2 Loan Commitment Schedule”) which sets forth the allocated commitments received by it with respect to the 2014 February Replacement Term A-2 Loans (the “2014 February Replacement Term A-2 Loan Commitments”) from the 2014 February Replacement Term A-2 Lenders and has notified each 2014 February Replacement Term A-2 Lender of its allocated 2014 February Replacement Term A-2 Loan Commitment. Each of the 2014 February Replacement Term A-2 Lenders by providing its 2014 February Replacement Term A-2 Loan Commitment has consented to the terms of this Sixth Amendment and, in the case of any New 2014 February Replacement Term A-2 Lender, shall become a party to the Amended Credit Agreement pursuant to one or more Assignment and Assumptions. On the Sixth Amendment Effective Date, all then outstanding Refinanced Term A-2 Loans shall be refinanced in full as follows:

(s) the outstanding aggregate principal amount of Refinanced Term A-2 Loans of each Lender that (i) is an existing Lender with respect to Refinanced Term A-2 Loans prior to giving effect to this Sixth Amendment (each, an “Existing Term A-2 Lender”) and (ii) is not a 2014 February Converting Term A-2 Lender (a Lender meeting the requirements of clauses (i) and (ii), each, a “2014 February Non-Converting Term A-2 Lender”) shall be repaid in full in cash with respect to its Refinanced Term A-2 Loans;

(t) to the extent any Existing Term A-2 Lender has a 2014 February Replacement Term A-2 Loan Commitment (for this purpose excluding any New 2014 February Replacement Term A-2 Loan Commitment) that is less than the full outstanding aggregate principal amount of Refinanced Term A-2 Loans of such Existing Term A-2 Lender as determined by DBSI and the Designated Borrower in accordance with clause (ii)(u) below, such Existing Term A-2 Lender shall be repaid in cash in an amount equal to the difference between such Existing Term A-2 Lender’s 2014 February Replacement Term A-2 Loan Commitment and the outstanding aggregate principal amount of such Existing Term A-2 Lender’s Refinanced Term A-2 Loans (the “Non-Converting Portion”);

(u) the outstanding aggregate principal amount of Refinanced Term A-2 Loans of each Existing Term A-2 Lender which has executed this Sixth Amendment as a “2014 February Converting Term A-2 Lender” (each, a “2014 February Converting Term A-2 Lender”) shall automatically be converted into 2014 February Replacement Term A-2 Loans (the “Converted 2014 February Replacement Term A-2 Loans”) in a principal amount equal to such 2014 February Converting Term A-2 Lender’s 2014 February Replacement Term A-2 Loan Conversion Amount (each such conversion, a “Term A-2 Loan Conversion”). For purposes of this Sixth Amendment, a 2014 February Converting Term A-2 Lender’s “2014 February Replacement Term A-2 Loan Conversion Amount” shall mean the amount determined by DBSI and the Designated Borrower as the final amount of such 2014 February Converting Term A-2 Lender’s Term A-2 Loan Conversion on the Sixth Amendment Effective Date and notified to each such 2014 February Converting Term A-2 Lender by DBSI promptly after the Sixth Amendment Effective Date. The “2014 February Replacement Term A-2 Loan Conversion Amount” of any 2014 February Converting Term A-2 Lender shall not exceed (but may be less than) the principal amount of such 2014 February Converting Term A-2 Lender’s Refinanced Term A-2 Loans immediately prior to the Sixth Amendment Effective Date. All such determinations made by DBSI and the Designated Borrower shall, absent manifest error, be final, conclusive and binding on the Designated Borrower, the Lenders and the Administrative Agent and neither the Designated Borrower nor DBSI shall have any liability to any Person with respect to such determination absent gross negligence or willful misconduct; and

(v) the Designated 2014 February Replacement Term A-2 Lender agrees to make to the Designated Borrower a New 2014 February Replacement Term A-2 Loan in Dollars in a principal amount equal to the aggregate principal amount of all New 2014 February Replacement Term A-2 Loan Commitments on the Sixth Amendment Effective Date.

(iii) Each 2014 February Replacement Term A-2 Lender hereby agrees to fund its 2014 February Replacement Term A-2 Loans in an aggregate principal amount equal to such 2014 February Replacement Term A-2 Lender’s 2014 February Replacement Term A-2 Loan Commitment as follows:

(A) each 2014 February Converting Term A-2 Lender shall fund its Converted 2014 February Replacement Term A-2 Loan to the Designated Borrower by converting all or a portion of its then outstanding principal amount of Refinanced Term A-2 Loans into a Converted 2014 February Replacement Term A-2 Loan in a principal amount equal to such 2014 February Converting Term A-2 Lender’s 2014 February Replacement Term A-2 Loan Conversion Amount as provided in clause (ii)(u) above, (B) each New 2014 February Replacement Term A-2 Lender shall fund in cash its 2014 February Replacement Term A-2 Loans in an aggregate principal amount equal to such New 2014 February Replacement Term A-2 Lender’s New 2014 February Replacement Term A-2 Loan Commitment to the Designated 2014 February Replacement Term A-2 Lender unless otherwise agreed by the Designated Borrower and the Administrative Agent and (C) and the Designated 2014 February Replacement Term A-2 Lender shall fund in cash to the Designated Borrower, on behalf of each New 2014 February Replacement Term A-2 Lender with a New 2014 February Replacement Term A-2 Loan Commitment, an amount equal to such New 2014 February Replacement Term A-2 Lender’s New 2014 February Replacement Term A-2 Loan Commitment.

(iv) The Converted 2014 February Replacement Term A-2 Loans subject to the Term A-2 Loan Conversion shall be allocated ratably to the outstanding Borrowings of Refinanced Term A-2 Loans (based upon the relative principal amounts of Borrowings of Refinanced Term A-2 Loans subject to different Interest Periods immediately prior to giving effect thereto). Each resulting “borrowing” of Converted 2014 February Replacement Term A-2 Loans shall constitute a new “Borrowing” under the Credit Agreement and be subject to the same Interest Period (and the same Eurocurrency Rate) applicable to the Borrowing of Refinanced Term A-2 Loans to which it relates, which Interest Period shall continue in effect until such Interest Period expires and a new Type of Borrowing is selected in accordance with the provisions of Section 2.02 of the Credit Agreement. New 2014 February Replacement Term A-2 Loans shall be initially incurred pursuant to one “borrowing” of Eurocurrency Rate Loans which shall be allocated ratably to the outstanding “deemed” Borrowings of Converted 2014 February Replacement Term A-2 Loans on the Sixth Amendment Effective Date (based upon the relative principal amounts of the deemed Borrowings of Converted 2014 February Replacement Term A-2 Loans subject to different Interest Periods on the Sixth Amendment Effective Date after giving effect to the foregoing provisions of this clause (iv)). Each such “borrowing” of New 2014 February Replacement Term A-2 Loans shall (i) be added to (and made a part of) the related deemed Borrowing of Converted 2014 February Replacement Term A-2 Loans and (ii) be subject to (x) an Interest Period which commences on the Sixth Amendment Effective Date and ends on the last day of the Interest Period applicable to the related deemed Borrowing of Converted 2014 February Replacement Term A-2 Loans to which it is added and (y) the same Eurocurrency Rate, applicable to such deemed Borrowing of Converted 2014 February Replacement Term A-2 Loans. The Applicable Rate of such Borrowing of 2014 February Replacement Term A-2 Loans shall be the Applicable Rate set forth in the Amended Credit Agreement.

(v) On the Sixth Amendment Effective Date, the Borrowers shall pay in cash (x) all interest accrued on the Refinanced Term A-2 Loans through the Sixth Amendment Effective Date and (y) to each 2014 February Non-Converting Term A-2 Lender and each 2014 February Converting Term A-2 Lender in respect of any Non-Converting Portion of that 2014 February Converting Term A-2 Lender, any breakage loss or expenses due under Section 3.05 of the Credit Agreement (it being understood that existing Interest Periods of the Refinanced Term A-2 Loans held by 2014 February Replacement Term A-2 Lenders prior to the Sixth Amendment Effective Date shall continue on and after the Sixth Amendment Effective Date pursuant to preceding clauses (iii) and (iv) and shall accrue interest in accordance with Section 2.08 of the Credit Agreement on and after the Sixth Amendment Effective Date as if the Sixth Amendment Effective Date were a new Borrowing date). Notwithstanding anything to the contrary in Section 1(a)(v) or in Section 3.05 of the Credit Agreement, each 2014 February Converting Term A-2 Lender hereby waives (other than in respect of any Non-Converting Portion of that 2014 February Converting Term A-2 Lender), and each New 2014 February Replacement Term A-2 Lender with a New 2014 February Replacement Term A-2 Loan Commitment irrevocably waives (by execution of an Assignment and Assumption with respect to any 2014 February Replacement Term A-2 Loans), any entitlement to any breakage loss or expenses due under Section 3.05 of the Credit Agreement with respect to the repayment of any Refinanced Term A-2 Loans it holds as an Existing Term A-2 Lender which have been converted into or replaced or repaid with 2014 February Replacement Term A-2 Loans on the Sixth Amendment Effective Date.

(vi) Promptly following the Sixth Amendment Effective Date, all Notes, if any, evidencing the Refinanced Term A-2 Loans shall be cancelled, and any 2014 February Replacement Term A-2 Lender may request that its 2014 February Replacement Term A-2 Loan be evidenced by a Note pursuant to Section 2.11(a) of the Credit Agreement.
