12

(g) The Depositor, both prior to and immediately after giving effect to the sale of Pool Loans to the Issuer on such date, (A) is not insolvent (as such term is defined in the Bankruptcy Code), (B) is able to pay its debts as they become due and (C) does not have unreasonably small capital for the business in which it is engaged or for any business or transaction in which it is about to engage.

It is understood and agreed that the representations and warranties contained in this Section 6 shall remain operative and in full force and effect, shall survive the transfer and conveyance of the Pool Loans by the Depositor to the Issuer and the grant of a security interest in the Pool Assets by the Issuer to the Collateral Agent and shall inure to the benefit of the Issuer, the Trustee, the Collateral Agent and the Noteholders and their respective designees, successors and assigns.

The Depositor hereby assigns to the Issuer its rights relating to the Series 2002-1 Pool Loans under the related Purchase Agreements, including without limitation any rights the Depositor may have to payments due from the related Seller for repurchases of Defective Loans (as such term is defined in such Purchase Agreement) resulting from the breach of representations and warranties made under such Purchase Agreement.

Section 9. Repurchases or Substitutions of Pool Loans for Breach of Representations and Warranties.

(a) Repurchase or Substitution Obligation. Subject to Section 9(b), upon discovery by the Depositor or the related Seller or upon written notice from the Issuer or the Trustee that any Series 2002-1 Pool Loan is a Defective Loan, the Depositor shall, or shall cause the applicable Seller to, within 90 days after the earlier of the discovery or receipt of notice thereof, cure such Defective Loan in all material respects or either (i) repurchase such Defective Loan from the Issuer or its assignee at the Repurchase Price or (ii) substitute one or more Qualified Substitute Loans for such Defective Loan. For purposes of this Agreement, the term “Repurchase Price” shall mean an amount equal to the outstanding Principal Balance of such Defective Loan as of the close of business on the Due Date immediately preceding the Payment Date on which the repurchase is to be made, plus accrued but unpaid interest thereon to the date of such repurchase. The Issuer hereby directs the Depositor, for so long as the Indenture and Servicing Agreement is in effect, to make such payment on its behalf to the Collection Account pursuant to Section 9(b). The following defects with respect to documents in any Loan File, solely to the extent they do not impair the validity or enforceability of the subject document

16

under applicable law, shall not be deemed to constitute a breach of the representations and warranties contained in Section 6(b) of the related Purchase Agreement: misspellings of or omissions of initials in names; name changes from divorce or marriage; discrepancies as to payment dates in a Series 2002-1 Pool Loan of no more than 30 days; discrepancies as to Scheduled Payments of no more than $5.00; discrepancies as to origination dates of not more than 30 days; inclusion of additional parties other than the primary Obligor not listed in the Master Servicer’s records or in the Series 2002-1 Pool Loan Schedule and non-substantive typographical errors and other non-substantive minor errors of a clerical or administrative nature.

(b) Repurchases and Substitutions. The Depositor shall provide written notice to the Issuer of any repurchase pursuant to Section 9(a) not less than two Business Days prior to the date on which such repurchase is to be effected, specifying the Defective Loan and the Repurchase Price therefor. Upon the repurchase of a Defective Loan pursuant to Section 9(a), the Depositor shall deposit, or shall cause the applicable Seller to deposit, the Repurchase Price in the Collection Account on behalf of the Issuer no later than 12:00 noon, New York time, on the Payment Date on which such repurchase is made (the “Repurchase Date”).

(c) Delivery Requirements. If the applicable Seller elects to substitute a Qualified Substitute Loan or Loans for a Defective Loan pursuant to the applicable PA Supplement, the Depositor shall deliver, or shall cause the applicable Seller to deliver, such Qualified Substitute Loan in the same manner as the other Series 2002-1 Pool Loans sold hereunder, including delivery of the applicable Loan Documents as required pursuant to the applicable Custodial Agreement and satisfaction of the same conditions with respect to such Qualified Substitute Loan as to the Purchase of Additional Pool Loans set forth in Section 2(b)(iii). No Qualified Substitute Loan shall be selected in a manner adverse to the Issuer or its assignees. Payments due with respect to Qualified Substitute Loans prior to the last day of the Due Period next preceding the date of substitution shall not be property of the Issuer, but will be retained by the Master Servicer and remitted by the Master Servicer to the Depositor for payment to the applicable Seller on the next succeeding Payment Date. Scheduled Payments due on a Defective Loan prior to the last day of the Due Period next preceding the date of substitution shall be property of the Issuer, and from and after such last day of the Due Period next preceding the date of substitution all Scheduled Payments due and other amounts received in respect of such Defective Loan shall be the property of the Depositor or the applicable Seller. The Depositor shall cause the Master Servicer to deliver a schedule of any Defective Loans so removed and Qualified Substitute Loans so substituted to the Issuer. Upon each such substitution, the Qualified Substitute Loan or Loans shall be subject to the terms of this PPA Supplement in all respects, and the representations and warranties of the applicable Seller under the related Purchase Agreement and PA Supplement with respect to each Qualified Substitute Loan shall be assigned to the Issuer hereunder. The Depositor shall be obligated to repurchase or substitute, or to cause the applicable Seller to repurchase or substitute, for any Qualified Substitute Loan as to which such Seller has breached such Seller’s representations and warranties in Section 6(b) of the related Purchase Agreement or applicable PA Supplement to the same extent as for any other Series 2002-1 Pool Loan, as provided herein or therein. In connection with the substitution of one or more Qualified Substitute Loans for one or more Defective Loans, the Depositor shall deposit, or shall cause the applicable Seller to deposit, an amount equal to the related Substitution Adjustment Amount (as defined in the related Purchase Agreement), if any (the “Substitution Adjustment Amount”), into the applicable Collection Account on the date of substitution, without any reimbursement therefor.

17

Upon each repurchase or substitution, the Issuer shall automatically and without further action sell, transfer, assign, set over and otherwise convey to the Depositor or to the related Seller, if applicable, without recourse, representation or warranty, all of the Issuer’s right, title and interest in and to such Defective Loan, the related Timeshare Property, the Loan File relating thereto and any other related Pool Assets, all monies due or to become due with respect thereto and all Pool Collections with respect thereto (including payments received from Obligors from and including the last day of the Due Period next preceding the date of transfer, subject to the payment of any Substitution Adjustment Amount). The Issuer shall execute such documents, releases and instruments of transfer or assignment and take such other actions as shall reasonably be requested by the Depositor or the Seller to effect the conveyance of such Defective Loan, the related Timeshare Property and related Loan File pursuant to this Section 9(c).

Promptly after the occurrence of a Repurchase Date and after the repurchase of or substitution for Defective Loans in respect of which the Repurchase Price has been paid or one or more Qualified Substitute Loans has been substituted therefor on such date, the Depositor shall direct the Master Servicer to delete such Defective Loans from the Series 2002-1 Pool Loan Schedule.

The obligation of the Depositor to repurchase or substitute for any Defective Loan shall constitute the sole remedy against the Depositor, the Sellers or their Affiliates with respect to any breach of the representations and warranties set forth in Section 6(b) of the applicable Purchase Agreement available hereunder to the Issuer or its successors or assigns.

Section 10. Representations and Warranties of the Issuer.

(f) All approvals, authorizations, consents or orders of any court or governmental agency or body required in connection with the execution and delivery by the Issuer of this Agreement or any other Facility Document to which it is a party, the consummation by it of the transactions contemplated hereby or thereby and the performance by it of, and the compliance by it with, the terms hereof or thereof, have been obtained, except where the failure to do so would not have a Material Adverse Effect with respect to the Issuer.

(g) The Issuer (A) is not insolvent (as such term is defined in the Bankruptcy Code), (B) is able to pay its debts as they become due and (C) does not have unreasonably small capital for the business in which it is engaged or for any business or transaction in which it is about to engage.

Without limiting any other rights that any Depositor Indemnified Party may have hereunder or under applicable law, the Depositor agrees to indemnify the Issuer and each of its successors, permitted transferees and assigns (including the Trustee for the benefit of Noteholders), and all officers, directors, shareholders, controlling Persons, employees and agents of any of the foregoing (each of the foregoing Persons, a “Depositor Indemnified Party”), from and against any and all damages, losses, claims (whether on account of settlements or otherwise), actions, suits, demands, judgments, liabilities (including penalties), obligations or disbursements of any kind or nature and related costs and expenses (including reasonable attorneys’ fees and disbursements) awarded against or incurred by any of them, arising out of or as a result of any of the following (all of the foregoing, collectively, “Depositor Indemnified Losses”):

21

(a) any representation or warranty made by the Depositor under any of the Facility Documents having been untrue or incorrect in any respect when made or deemed to have been made; provided, however, that the Depositor’s obligation to repurchase Defective Loans pursuant to Section 9 with respect to any representation assigned to the Issuer pursuant to this Agreement having been incorrect when made shall be the only remedy available to the Issuer or its assignees relating to such incorrect representation;

(b) the failure to vest and maintain in the Issuer a first priority perfected ownership or security interest in the Pool Assets, free and clear of any Lien arising through the Depositor or anyone claiming through or under the Depositor; or

(c) any failure of the Depositor to perform its duties or obligations in accordance with the provisions of any Facility Documents to which it is a party.

Notwithstanding the foregoing, no indemnification payments shall be payable by the Depositor pursuant to this Section 14 except to the extent of funds available to the Depositor for such purpose.

Notwithstanding the foregoing (and with respect to clause (ii) below, without prejudice to the rights that the Issuer may have pursuant to the other provisions of this Agreement or the provisions of any of the other Facility Documents), in no event shall any Depositor Indemnified Party be indemnified for any Depositor Indemnified Losses (i) resulting from negligence or willful misconduct on the part of such Depositor Indemnified Party, (ii) to the extent the same includes losses in respect of Pool Assets and reimbursement therefor that would constitute credit recourse to the Depositor for the amount of any Pool Asset not paid by the related Obligor or (iii) resulting from the action or omission of the Master Servicer.

If for any reason the indemnification provided in this Section 14 is unavailable to a Depositor Indemnified Party or is insufficient to hold a Depositor Indemnified Party harmless, then the Depositor shall contribute to the maximum amount payable or paid to such Depositor Indemnified Party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by such Depositor Indemnified Party on the one hand and the Depositor on the other hand, but also the relative fault of such Depositor Indemnified Party and the Depositor, and any other relevant equitable considerations.

It is the express and specific intent of the parties that the transfer of the Additional Pool Loans and the other Additional Pool Assets from the Depositor to the Issuer as provided is and shall be construed for all purposes as a true and absolute sale of such Additional Pool Loans and Additional Pool Assets, shall be absolute and irrevocable and provide the Issuer with the full benefits of ownership of the Additional Pool Loans and the other Additional Pool Assets.
