1.2                               Amendments to Section 10.6.

Section 10.6 of the Credit Agreement is hereby amended by inserting a new Section 10.6(i) immediately after the end of Section 10.6(h) as follows:

“(i)  Certain Permitted Loan Purchases.  Notwithstanding anything to the contrary contained in this Section 10.6 or any other provision of this Agreement or any other Credit Document, so long as no Default or Event of Default has occurred and is continuing or would result therefrom, any Lender may sell, assign or transfer all or a portion of its rights and obligations under this Agreement with respect to its outstanding Loans to the Borrower for cash pursuant to the terms of a Borrower Assignment Agreement, and the Borrower may purchase all or a portion of any Lender’s rights and obligations under this Agreement with respect to its outstanding Loans from any Lender for cash pursuant to the terms of a Borrower Assignment Agreement, in each case, on the following basis:

(iii)          Following the Borrower Assignment Effective Date, no interest shall accrue on the Loans so assigned or sold and such Loans shall be cancelled or retired and no longer outstanding (and may not be re-assigned or resold by the Borrower), for all purposes under this Agreement and all other Credit Documents (notwithstanding any provisions herein or therein to the contrary), including, but not limited to (A) the making of, or the application of, any payments to the Lenders under this Agreement or any other Credit Document, (B) the making of any request, demand, authorization, direction, notice, consent or waiver under this Agreement or any other Credit Document, (C) the providing of any rights to the Borrower as a Lender under this Agreement or any other Credit Document, and (D) the determination of Requisite Lenders, or for any similar or related purpose, under this Agreement or any other Credit Document.

Agreement, a Default or an Event of Default as a direct result of any transaction described in this Section 10.6(i).

(v)           The provisions of this Section 10.6(i) shall not require the Borrower to purchase or undertake any offer to purchase any Loans.

(vi)          The parties hereto acknowledge that the payment by the Borrower for any Loans purchased pursuant to the terms of this Section 10.6(i) shall be made directly to each Lender who has executed a Borrower Assignment Agreement in connection with any such assignment or transfer based on the information set forth in the applicable Borrower Assignment Agreement and the Register.
