     Series 2002-1 Loans, such Additional Series 2002-1 Loans shall become

                     (B)     On each of the Addition Cut-Off Date and the
             Addition Date, the sale of such Additional Series 2002-1 Loans and
             the other related Transferred Assets to the Purchaser shall not

                     (C)     No selection procedure shall have been utilized by

             computer and other records that the Additional Series 2002-1 Loans

             Receivables Funding Company, LLC on the date of this PA Supplement;
             and

                     (H)     The Purchaser shall have paid the Additional Pool
             Purchase Price as provided in Section 3 of the Agreement.

                     (iv)    The Seller shall have no obligation to sell the

sale of such Series 2002-1 Loans and related Transferred Assets, shall be
absolute and irrevocable and provide the Company with the full benefits of

             (f)     RECHARACTERIZATION. Without prejudice to the provisions of
Section 2(e) providing for the absolute transfer of the Seller's interest in the

Seller to the Company and the Company's assignees arising in connection with the
Agreement, this PA Supplement and the other Facility Documents, whether now or
hereafter existing, due or to become due, direct or indirect, or absolute or
contingent, the Seller hereby assigns and grants to the Company a first priority
security interest in all of the Seller's right, title and interest, whether now
owned or hereafter acquired, if any, in, to and under all of the Series 2002-1
Loans and related Transferred Assets and the proceeds thereof.

             (g)     SECURITY INTEREST IN TRANSFERRED ASSETS. The Seller

directly, including without limitation the repurchase obligations of the Seller
set forth in Section 7.

                     Purchaser of its obligations under this PA Supplement.

             (ii)    The representations and warranties of the Seller made in

     related Transferred Assets except as contemplated by the Facility
     Documents);

             (ii)    Copies of proper UCC Financing Statement Amendments (Form

SECTION 6.   REPRESENTATIONS AND WARRANTIES OF THE SELLER.

             (a)     REPRESENTATIONS AND WARRANTIES OF THE SELLER. The Seller
represents and warrants as of the Closing Date and as of each Addition Date, or
as of such other date specified in such representation and warranty, that:

                     (xvii)  ACCURACY OF INFORMATION. All information with
     respect to the Seller contained in the Confidential Information Memorandum
     dated June 2002 with respect to the Series 2002-1 Notes and Series 2002-1
     Loans (including, without limitation, the Credit Standards and Collection
     Policies) was true and accurate in every respect material to the
     transactions contemplated hereby on the date as of which it was delivered,
     and did not omit to state any fact necessary to make the statements
     contained therein not materially misleading or, if any such information
     contained therein has been discovered to have been inaccurate on such date,
     such information has been corrected by subsequent information provided in
     writing to the Issuer.

                                        9
<Page>

                     (xviii) NO MATERIAL ADVERSE CHANGE. As of the Closing Date,
     there has been no material adverse change with respect to the business
     operations or financial condition of the Seller since December 31, 2001.

     Sections 6(a)(i) through (xvi) are set forth in the Agreement.

             (b)     REPRESENTATIONS AND WARRANTIES REGARDING THE SERIES 2002-1
LOANS. The Seller represents and warrants to the Company as of the Cut-Off Date
and Addition Cut-Off Date as to each Series 2002-1 Loan conveyed on and as of
the Closing Date or the related Addition Date, as applicable (except as
otherwise expressly stated) as follows:

                     (xxiii) LOAN SCHEDULE. The information set forth in the
     Series 2002-1 Loan Schedule is true and correct with respect to such Series
     2002-1 Loan.

                     (xxiv)  GOOD TITLE TO SERIES 2002-1 LOANS. The Seller has
     good and marketable title to such Series 2002-1 Loan free and clear of any
     Lien other than Permitted Encumbrances. The Seller has not sold, assigned
     or pledged such Series 2002-1 Loan or any interest therein to any Person
     other than the Company. With respect to the related Timeshare Property,
     either (A) a generally accepted form of title insurance policy insuring the
     fee estate ownership of the real property subject to the Timeshare Property
     Regime by the Persons owning the respective interests therein and their
     successors and assigns (1) was effective either at the time the Developer
     (or a Subsidiary thereof) acquired the Timeshare Property or at the time of
     registration of the Timeshare Property Regime, (2) is valid and remains in
     full force and effect and (3) was issued by a title insurer qualified to do
     business in the applicable jurisdiction; or (B) either at the time the
     Developer (or a Subsidiary thereof) acquired the Timeshare Property or at
     the time of registration of the Timeshare Property Regime, such fee estate
     ownership had been verified by an attorney's opinion of title, the form and
     substance of which is of a type acceptable for purposes of registration of
     sales of Timeshare Properties and which may be relied upon by Persons
     subsequently owning the respective interests therein and their successors
     and assigns.

                     (xxv)   NO DEFAULTS. As of the Cut-Off Date or related
     Addition Cut-Off Date, as applicable, such Series 2002-1 Loan is not a
     Defaulted Loan and no event has occurred which, with the taking of any
     action or the expiration of any grace or cure period or both, would cause
     such Series 2002-1 Loan to be a Defaulted Loan. The Seller has not waived
     any such default, breach, violation or event permitting acceleration with
     respect to such Series 2002-1 Loan.

                     (xxvi)  EQUAL INSTALLMENTS. Such Series 2002-1 Loan has a
     fixed Loan Rate and provides for substantially equal monthly payments that
     fully amortize the Series 2002-1 Loan over its term.

                     (xxvii) EXCESS CONCENTRATION AMOUNT. The Purchase of such
     Series 2002-1 Loan occurring on such Closing Date or Addition Date, as
     applicable, and the inclusion of such Series 2002-1 Loan as a Series 2002-1
     Pledged Loan pursuant to the

                                       10
<Page>

     Series 2002-1 Supplement to the Indenture and Servicing Agreement, does not
     cause an increase in the Excess Concentration Amount.

     Sections 6(b)(i) through (xxii) are set forth in the Agreement.

SECTION 7.   REPURCHASES OR SUBSTITUTION OF SERIES 2002-1 LOANS.

             (a)     REPURCHASE OR SUBSTITUTION OBLIGATION. Subject to
Section 7(b), upon discovery by the Seller or upon written notice from the
Company, the Issuer or the Trustee that any Series 2002-1 Loan is a Defective
Loan, the Seller shall, within 90 days after the earlier of its discovery or
receipt of notice thereof, cure such Defective Loan in all material respects or
either (i) repurchase such Defective Loan from the Company 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 the repurchase. The Company hereby directs the
Seller, 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
7(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 under applicable law, shall not be deemed to constitute a breach of the
representations and warranties contained in Section 6(b): misspellings of or
omissions of initials in names; name changes from divorce or marriage;
discrepancies as to payment dates in a Series 2002-1 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 Loan Schedule and non-substantive
typographical errors and other non-substantive minor errors of a clerical or
administrative nature.

             (b)     REPURCHASES AND SUBSTITUTIONS. The Seller shall provide
written notice to the Company of any repurchase pursuant to Section 7(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 7(a), the Seller shall
deposit the Repurchase Price in the Collection Account on behalf of the Company
no later than 12:00 noon, New York time, on the Payment Date on which such
repurchase is made (the "REPURCHASE DATE").

     If the Seller elects to substitute a Qualified Substitute Loan or Loans for
a Defective Loan pursuant to this Section 7(b), the Seller shall deliver such
Qualified Substitute Loan in the same manner as the other Series 2002-1 Loans
sold hereunder, including delivery of the applicable Loan Documents as required
pursuant to the Custodial Agreement and satisfaction of the same conditions with
respect to such Qualified Substitute Loan as to the Purchase of Additional Loans
set forth in Section 2(d)(iii). 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 Company, but will be retained by
the Master Servicer and remitted by the Master Servicer to the

                                       11
<Page>

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 Company, and after such last day of the
Due Period next preceding the date of substitution the Seller shall be entitled
to retain all Scheduled Payments due thereafter and other amounts received in
respect of such Defective Loan. The Seller shall cause the Master Servicer to
deliver a schedule of any Defective Loans so removed and Qualified Substitute
Loans so substituted to the Company and such schedule shall be an amendment to
the Series 2002-1 Loan Schedule. Upon such substitution, the Qualified
Substitute Loan or Loans shall be subject to the terms of this PA Supplement in
all respects, the Seller shall be deemed to have made the representations and
warranties with respect to each Qualified Substitute Loan set forth in Section
6(b) of the Agreement and this PA Supplement and Section 6(c) of the Agreement,
in each case as of the date of substitution, and the Seller shall be deemed to
have made a representation and warranty that each Loan so substituted is an
Qualified Substitute Loan as of the date of substitution. The Seller shall be
obligated to repurchase or substitute for any Eligible Substitute Loan as to
which the Seller has breached the Seller's representations and warranties in
Section 6(b) to the same extent as for any other Series 2002-1 Loan, as provided
herein. In connection with the substitution of one or more Qualified Substitute
Loans for one or more Defective Loans, the Master Servicer shall determine the
amount (such amount, a "SUBSTITUTION ADJUSTMENT AMOUNT"), if any, by which the
aggregate principal balance of all such Qualified Substitute Loans as of the
date of substitution is less than the aggregate principal balance of all such
Defective Loans (after application of the principal portion of the Scheduled
Payments due in the month of substitution that are to be distributed to the
Company in the month of substitution). The Seller shall deposit the amount of
such shortfall into the Collection Account in immediately available funds on the
date of substitution, without any reimbursement therefor.

     Upon each repurchase or substitution, the Company shall automatically and
without further action sell, transfer, assign, set over and otherwise convey to
the Seller, without recourse, representation or warranty, all of the Company's
right, title and interest in and to the related Defective Loan, the related
Timeshare Property, the Loan File relating thereto and any other related
Transferred Assets, all monies due or to become due with respect thereto and all
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
Company shall execute such documents, releases and instruments of transfer or
assignment and take such other actions as shall reasonably be requested by the
Seller to effect the conveyance of such Defective Loan, the related Timeshare
Property and related Loan File pursuant to this Section 7(b).

     Promptly after the occurrence of a Repurchase Date and after the repurchase
of Defective Loans in respect of which the Repurchase Price has been paid on
such date, the Seller shall direct the Master Servicer to delete such Defective
Loans from the Series 2002-1 Loan Schedule.

     The obligation of the Seller to repurchase or substitute for any Defective
Loan shall constitute the sole remedy against the Seller with respect to any
breach of the representations and warranties set forth in Section 6(b) available
hereunder to the Company or its successors or assigns.

                                       12
<Page>

             (c)     REPURCHASES OF SERIES 2002-1 LOANS THAT BECOME DEFAULTED
LOANS. If any Series 2002-1 Loan becomes a Defaulted Loan during any Due Period,
the Seller may repurchase such Defaulted Loan from the Company or its assignees
at the Repurchase Price therefor and in accordance with the additional
provisions applicable to repurchases of Defective Loans under Section 7(b).

             (d)     MAXIMUM REPURCHASES. Notwithstanding anything to the
contrary in the Agreement or this PA Supplement, no Defaulted Loans shall be
repurchased by the Seller to the extent that the aggregate principal balance of
all Defaulted Loans so repurchased is greater than the Defaulted Loan Repurchase
Cap.
