                                   ARTICLE IV
                               PAYMENTS; MATURITY

         SECTION 4.01 Payment of Interest. From (and including) the Certificate
Issuance Date, interest will be paid on the outstanding principal of the Series
2000-1 A-RI Certificate in an amount equal to the amount of interest that is
required to be paid from time to time on the Revolving Loans pursuant to the
Revolving Credit Agreement. In addition, whenever fees, costs, expenses,
indemnities or any other amounts (excluding repayments of principal) are
required to be paid under the Revolving Credit Agreement (all of the foregoing
being herein collectively called the "Supplemental Interest Payments"),
additional interest will be paid on the Series 2000-1 A-RI Certificate in an
amount equal to the aggregate amount of Supplemental Interest Payments that are
then required to be paid pursuant to the Revolving Credit Agreement. The rate of
interest on the Series 2000-1 A-RI Certificate shall be a per annum variable
rate which, when multiplied by the then Ratable Principal Amount of the Series
2000-1 A-RI Certificate, will result in an amount to be paid as interest that is
equal to the sum of (x) the amount of interest, plus (y) the aggregate amount of
Supplemental Interest Payments that, in the case of each of the foregoing, are
then required to be paid under the Revolving Credit Agreement. Except as
expressly provided otherwise in this Agreement, interest on the Series 2000-1
A-RI Certificate (including the Supplement Interest Payments, if applicable)
shall accrue on a daily basis for each period from (and including) the preceding
Payment Date to (but excluding) the then-current Payment Date and shall be
payable on each Payment Date in arrears in the order of priority set forth in
Article V of the Pooling and Servicing Agreement, and shall be paid to the
Collateral Agent without set-off or counterclaim.

         SECTION 4.02 Payment of Principal. Except as provided otherwise in this
Agreement, principal payments on the Series 2000-1 A-RI Certificate will
commence on the Settlement Date (the "First Scheduled Principal Payment Date")
that occurs in the month following the Scheduled Pay-Out Commencement Date, and
will be made on each subsequent Settlement Date until the principal amount of
the Series 2000-1 A-RI Certificate has been paid in full; provided, however,
that principal payments with respect to the Series 2000-1 A-RI Certificate may
commence prior to the First Scheduled Principal Payment Date if (a) the
Liquidation Commencement Date has occurred on an earlier date, or (b) a Pay-Out
Period with respect to the Series 2000-1 A-RI Certificate has occurred prior to
the First Scheduled Principal Payment Date as a result of the occurrence of one
of the events described in clause (b) or (c) of the definition of "Pay-Out
Period Commencement Date." Principal payment on the Series 2000-1 A-RI
Certificate shall be made in the order of priority set forth in Article V of the
Pooling and Servicing Agreement, and shall be paid to the Collateral Agent
without set-off or counterclaim.

         SECTION 4.03 Maturity; Extension of Maturity. The stated maturity date
of the Series 2000-1 A-RI Certificate is the one year anniversary of the
Commitment Termination Date. The stated maturity of the Series 2000-1 A-RI
Certificate will be extended if the Scheduled Pay-Out Commencement Date is
extended as provided in this Section 4.03 . During the third month prior




                                                 Series 2000-1 A-RI Supplemental

<PAGE>   10


to each anniversary of the Closing Date (commencing on the third anniversary)
prior to the occurrence of the earlier of (x) the Scheduled Pay-Out Commencement
Date or (y) the Liquidation Commencement Date, GRC may notify the Collateral
Agent that GRC wishes to extend the Scheduled Pay-Out Commencement Date by one
additional year. If the Scheduled Commitment Termination Date is extended
pursuant to Section 3.03 of the Revolving Credit Agreement, then the Collateral
Agent will agree to extend the Scheduled Pay-Out Commencement Date for one
additional year, and the stated maturity of the Series 2000-1 A-RI Certificate
shall also be extended for an additional year.

                                    ARTICLE V
                            CERTAIN MATTERS RELATING

is, at any time, the then outstanding principal amount thereof.

         SECTION 5.02 Stated Amount of Series 2000-1 ARI Certificate. (a) The
Stated Amount of the Series 2000-1 A-RI Certificate is $125,000,000 (the "Series
2000-1 A-RI Stated Amount"). The Ratable Principal Amount of the Series 2000-1
A-RI Certificate shall at no time exceed the Series 2000-1 A-RI Stated Amount.

         (b) If, at any time, the Revolving Commitment under the Revolving
Credit Agreement shall be increased, the Series 2000-1 A-RI Stated Amount shall
automatically be increased by a corresponding amount until it equals the amount
of the Revolving Commitment. If, at any time, the Revolving Commitment under the
Revolving Credit Agreement shall be decreased, the Series 2000-1 A-RI Stated
Amount shall automatically be decreased by a corresponding amount until it
equals the amount of the Revolving Commitment, as so reduced.

         SECTION 5.03 Increase of the Ratable Principal Amount. (a) If on any
day GRC allocates a positive Variable Amount or all or part of the Class A-RF
Amount to the Series 2000-1 A-RI Certificate pursuant to Section 4.03(c) of the
Pooling and Servicing Agreement, then: (i) the Ratable Principal Amount of the
Series 2000-1 A-RI Certificates will be deemed to have been increased by such
Variable Amount and/or all or part of the Class A-RF Amount, and (ii) GRC
whereupon shall have the right to request the Lenders, in accordance with the
procedures set forth in (and subject to the limitations of) the Revolving Credit
Agreement, to make Revolving Loans to GRC in an amount not to exceed such
Variable Amount and/or all or part of the Class A-RF Amount; provided, however,
that GRC shall not be entitled to request the Lenders, and the Lenders shall not
be obligated, to make or increase the Revolving Loans during any grace period
that has been extended by operation of the first proviso to Section 9.01(a) of
the Pooling and Servicing Agreement. GRC may make such a request at any time
prior to the earlier of (i) the Liquidation




                                                 Series 2000-1 A-RI Supplemental
                                       7                      Issuance Agreement

Commencement Date and (ii) the Pay-Out Period Commencement Date. Any Revolving
Loans, if and when made under the Revolving Credit Agreement, shall be deemed to
be funds provided by the Collateral Agent, as the holder of the Series 2000-1
A-RI Certificate, to GRC for funding of the Ratable Principal Amount of the
Series 2000-1 A-RI under this Agreement.

         Without limiting anything provided in the immediately preceding
sentence, each party hereby acknowledges that any increase of the Ratable
Principal Amount shall not exceed the sum, if positive, of (a) the Variable
Amount on the day on which such increase takes effect (as described hereinafter)
and (b) the amount of the Class A-RF Certificate as of the opening of business
on such day.

              (b) If the conditions set forth in the Revolving Credit Agreement
to making the Revolving Loans requested by GRC shall have been satisfied, the
Lenders shall, in accordance with the Revolving Credit Agreement, provide their
respective Revolving Percentages of such requested Revolving Loans to the
Facility Agent for delivery to GRC. The Collateral Agent, as the holder of the
Series 2000-1 A-RI Certificate, shall be deemed to have provided such funds to
GRC in order to fund, or to effect an increase in, the Ratable Principal Amount
of the Series 2000-1 A-RI Certificate pursuant to the terms and subject to the
conditions set forth in this Agreement and the Pooling and Servicing Agreement
upon GRC's receipt of such funds from the Facility Agent (on behalf of the
Lenders). The outstanding Ratable Principal Amount of the Series 2000-1 A-RI
Certificate shall be increased, on the Business Day on which GRC receives
immediately available funds from the Facility Agent on behalf of the Lenders, by
the amount of funds that GRC receives on such day from the Facility Agent.

         SECTION 5.04 Decrease of the Ratable Principal Amount. (a) If on any
day GRC allocates a negative Variable Amount to the Series 2000-1 A-RI
Certificate pursuant to Section 4.03(c) of the Pooling and Servicing Agreement,
the Ratable Principal Amount of the Series 2000-1 A-RI Certificate shall be
automatically decreased by the absolute value of such negative amount. If, as a
result of such decrease, the amount funded under the Series 2000-1 A-RI
Certificate shall exceed the Ratable Principal Amount (as so decreased) of the
Series 2000-1 A-RI Certificate, GRC shall immediately pay or cause to be paid to
the Collateral Agent, as the holder of the Series 2000-1 A-RI Certificate, an
amount equal to such excess pursuant to the Third or Fifth (as applicable)
priorities set forth in Section 4.03(f) of the Pooling and Servicing Agreement.

         (b) At any time when GRC is required to reduce the Ratable Principal
Amount of the Series 2000-1 A-RI Certificate pursuant to Section 2.03(b) of the
Revolving Credit Agreement and to make a corresponding payment to the Facility
Agent (to reimburse the Facility Agent for a mistaken funding), GRC shall effect
a reduction in the Ratable Principal Amount of the Series 2000-1 A-RI
Certificate pursuant to Section 4.03(c) of the Pooling and Servicing Agreement
by causing funds to be paid to the Collateral Agent, as the holder of the Series
2000-1 A-RI Certificate (as provided in Section 2.02), pursuant to clause Third
or Seventh (as applicable) of Section 4.03(f) of the Pooling and Servicing
Agreement in an amount equal to the amount of the reduction calculated

pursuant to Section 2.03(b) of the Revolving Credit Agreement. If there is a
shortfall in the amount of Collections available for such purpose and GRC used
the proceeds of such funding to pay to Gaylord the Purchase Price for new
Receivables or amounts owed on the GRC Note, Gaylord shall immediately pay to
GRC an amount equal to such shortfall.

              (c) At any time when the Series 2000-1 A-RI Stated Amount is
reduced pursuant to Section 5.02(b), GRC shall, contemporaneously therewith,
effect a reduction in the Ratable Principal Amount of the Series 2000-1 A-RI
Certificate pursuant to Section 4.03(c) of the Pooling and Servicing Agreement,
to the extent that such Ratable Principal Amount then exceeds the Series 2000-1
A-RI Stated Amount as so reduced, by causing funds to be paid to the Collateral
Agent, as the holder of the Series 2000-1 A-RI Certificate (as provided in
Section 2.02), pursuant to clause Third or Seventh (as applicable) of Section
4.03(f) of the Pooling and Servicing Agreement until the Ratable Principal
Amount of the Series 2000-1 A-RI Certificate equals the Series 2000-1 A-RI
Stated Amount as so reduced.

              (d) Notwithstanding anything to the contrary in the Pooling and
Servicing Agreement, any reduction that GRC effects in the Ratable Principal
Amount of the Series 2000-1 A-RI Certificate by means of an allocation that GRC
directs the Servicer to make pursuant to Section 4.03(c) of the Pooling and
Servicing Agreement, other than any such reduction that is described above in
Section 5.04(b), shall be in a minimum amount of $1,000,000 and in increments of
$100,000 in excess thereof.

              (e) The amount of interest to be paid to the Collateral Agent, as
the holder of the Series 2000-1 A-RI Certificate (pursuant to Section 2.02),
upon any reduction of all or part of the outstanding Ratable Principal Amount of
the Series 2000-1 A-RI Certificate shall include interest accrued on the amount
of such reduction to the date on which such reduction is to be made.

         SECTION 5.05 Restrictions on Issuance of Certain Additional Series of
Investor Certificates. GRC and the Trustee hereby agree that, at any time when
the Series 2000-1 A-RI Certificate is issued and outstanding, it will be the
only issued and outstanding Class A-RI Certificate.
