At either its own option or that of AFC, Seller shall endorse each Installment Contract as follows:

“For value received, the undersigned hereby sells, transfers and assigns to AFC all its right, title and interest in and to the within instrument and any real or personal property securing the obligations evidenced thereby.”

The assignment of an Installment Contract, which shall be effective as of Seller’s receipt in good funds of payment under Section 7 below, shall include assignment of all Seller’s right, title and interest to said Installment Contract, all documentation evidencing or executed or provided by the Customer in connection therewith, all of Seller’s rights thereunder, including without limitation Seller’s rights to insurance proceeds or insurance policies relating to such Installment sale Contract or the underlying real or personal property, and all proceeds of any of the foregoing. The Assignment shall be WITHOUT RECOURSE except to the limited extent provided in Section 8 below.

8. Breach; Repurchase; Termination. In the event of a breach of any representation, warranty or covenant of Seller, any claim by a Customer based upon allegations of fact which if found to be true would constitute a breach of Seller’s warranties herein or if Seller or AFC is named as a defendant or responding party in any administrative, regulatory, or judicial proceeding or complaint based upon allegations of fact which if found to be true would constitute a breach of Seller’s warranties or representations herein, Seller shall:

(a) At AFC’s request, immediately repurchase the Installment Contract affected by the breach of representation or warranty or alleged breach of representation or warranty by paying to AFC the total purchase price for such account, plus accrued interest at the rate set forth in the Installment Contract, plus expenses, less actual payments received by AFC after purchase. Said repurchase is without any representation, warranty or recourse on part of AFC; and

(b) On demand, hold AFC, its parent, subsidiaries, affiliates, lenders, successors and assigns and their respective officers, employees, agents and directors free and harmless from any resulting claims, losses, costs, damages, punitive damages, penalties, any return, forgiveness or cancellation of all or any part of the principal or interest paid or payable on any Account, any attorney fees, legal fees or expenses imposed or sought to be imposed upon it, however denominated, and, at AFC’s option, forthwith enter and defend AFC at Seller’s sole expense in any judicial, administrative, or regulatory proceedings using counsel selected by AFC.

Either party may terminate this Agreement in writing at any time and for any reason by thirty (30) days written notice of termination. The provisions of this Agreement which by their plain meaning are intended to survive termination shall so survive. Termination of this Agreement shall not release either party hereto from any of its responsibilities or liabilities related to such transactions unless and until a party expressly agrees in writing to release the other from those responsibilities or liabilities.

11. Governing Law. This Agreement has been executed in and shall be governed by the laws of the Commonwealth of Pennsylvania.

12. Assignment. The rights and obligations under this Agreement shall not be assigned by either party, except with the prior written consent of the other party, which consent shall not be unreasonably withheld.

13. Entire Agreement. The terms contained herein constitute the entire agreement of the parties with respect to the matters herein. Any representations or agreements that may have been made by any party prior to the execution of this Agreement with respect to such matters are void, and neither of the parties has relied on such prior representation in executing this Agreement. The recitals set forth above are included herein as if set forth in full. If any one or more of the provisions contained in this Agreement for any reason are held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision thereof and this Agreement shall be construed as if such invalid, illegal, or unenforceable provision had never been contained herein.
