If any amount shall be paid to Wyndham Worldwide as Performance Guarantor under this Agreement on account of such subrogation rights at any time prior to the payment in full of all amounts described in the prior sentence, such amount shall be held in trust for the benefit of the Guaranteed Parties and shall forthwith be paid to the Guaranteed Parties to be credited and applied upon the Obligations owed to the Guaranteed Parties, in accordance with the terms of the Transaction Documents. If (i) Wyndham Worldwide shall make payment to the Guaranteed Parties of all or any part of the

Obligations and, (ii) all Obligations and all other amounts payable under this Guaranty shall be paid in full, the Guaranteed Parties will, at Wyndham Worldwide’s request, execute and deliver to the Performance Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Performance Guarantor of an interest in the Obligations resulting from any such payment made by the Performance Guarantor hereunder. Notwithstanding the foregoing or any other provision of this Guaranty, WRDC, WCF, or the Issuer may enter into a reimbursement agreement with Wyndham Worldwide under which WRDC, WCF, or the Issuer agrees to reimburse the Performance Guarantor for amounts the Performance Guarantor may be obligated to pay under this Guaranty as long as any such reimbursement shall be paid only from amounts that are not subject to the lien of the Indenture.
