ITEM 5.  OTHER EVENTS

         On March 4, 1998, the registrant, Dollar Thrifty Automotive Group,
Inc., a Delaware corporation ("Company"), completed the establishment of a $615
million commercial paper facility ("Commercial Paper Facility") which will
provide vehicle fleet financing for the ongoing operations of the Company's
wholly-owned operating subsidiaries, Dollar Rent A Car Systems, Inc., an
Oklahoma corporation ("Dollar"), and Thrifty Rent-A-Car System, Inc., an
Oklahoma corporation ("Thrifty").  The commercial paper will be issued by the
Company's wholly-owned finance subsidiary, Dollar Thrifty Funding Corp., an
Oklahoma corporation ("DTFC").  While DTFC will issue the commercial paper
notes, it will actually use the proceeds to purchase a variable funding note
("VFN") from the Company's other wholly-owned finance subsidiary, Rental Car
Finance Corp. ("RCFC").  RCFC will, in turn, use such proceeds to purchase
vehicles for lease to Dollar and Thrifty.

         The commercial paper issued under the Commercial Paper Facility is
supported by collateral for the VFN. The VFN is secured by a grant to a trustee
under an indenture relating to issuance of RCFC asset backed notes (including
the VFN) of a first priority security interest in (i) the Master Motor Vehicle
Lease and Servicing Agreement among RCFC, as lessor, Dollar and Thrifty, as
lessees and servicers, and the Company, as guarantor and master servicer (the
"Lease Agreement"), and payments due thereunder covering certain vehicles that
are not collateral for other outstanding asset backed notes, (ii) a credit
enhancement letter of credit in the initial amount of $5 million (which must be
increased depending upon the amount of commercial paper issued) from Credit
Suisse First Boston which, in addition to providing credit enhancement, also
supports payments due from Dollar and Thrifty under the Lease Agreement, (iii) a
capitalization demand promissory note in the amount of $7.3 million from the
Company to RCFC relating to establishment of the Commercial Paper Facility, (iv)
through a master collateral agency arrangement (the "Master Collateral
Agreement"), vehicles leased under the Lease Agreement and all proceeds from
disposition of such vehicles, and the rights relating to the obligations of
certain approved manufacturers (the "Approved Manufacturers"), pursuant to their
manufacturing programs to repurchase or guarantee minimum resale prices of such
vehicles (the "Manufacturer Programs"), including the receivables due from the
Approved Manufacturers in connection therewith, (v) any cash or investments in
the various accounts held pursuant to the Master Collateral Agreement by a
master collateral agent related to the vehicles, and (vi) any cash or
investments in the various accounts held by the trustee allocable to the VFN.

         To support the Commercial Paper Facility, DTFC entered into a secured
364-day revolving liquidity facility (the "Liquidity Facility") provided by a
syndicate of financial institutions (the "Liquidity Banks").  The aggregate
commitments under the Liquidity Facility equal $545 million.  The Liquidity
Facility provides the Commercial Paper Facility with a back-up source of
funding if DTFC is unable to refinance maturing commercial paper by issuing new
commercial paper.  The Liquidity Facility is secured by the same collateral for
the VFN as described in the paragraph immediately above.

         The Company will use $256 million of the proceeds from the Commercial
Paper Facility to refinance the portion of RCFC's outstanding asset backed
notes which begin amortizing from September 1998 through February 1999.  The
Company will use the remaining amounts available under the Commercial Paper
Facility for fleet financing and to refinance asset backed notes from time to
time.  Commercial paper will be issued at interest rates prevailing in the
market at the time of issuance, or sold at a discount reflecting such rates.
In the event commercial paper cannot be reissued in the market, DTFC will use
proceeds advanced under the Liquidity Facility to repay maturing commercial
paper notes.

         The Liquidity Banks will be obligated to fund loans to repay maturing
commercial paper or maturing liquidity loans.  Draws under the Liquidity
Facility will be repaid with proceeds from subsequent Liquidity Facility draws
or the issuance of additional commercial paper and payments made by RCFC on the
VFN.  Payments on the VFN will be made from collections of lease payments
received from Dollar and Thrifty, payments under the Manufacturer Programs, and
proceeds from the sale of Non-Program Vehicles (as defined below) and other
vehicle sale proceeds.





                                      -2-
<PAGE>   3
         At least 80% of vehicles (such vehicles, "Program Vehicles") financed
by RCFC with advances under the VFN will be eligible under Manufacturer
Programs maintained by Approved Manufacturers pursuant to which either (i) in
the case of manufacturer repurchase programs, each manufacturer will be
obligated to repurchase vehicles within designated periods of time, or (ii) in
the case of guaranteed depreciation programs, each manufacturer will reimburse
any difference between the aggregate gross auction sale price of the Program
Vehicles for a particular model year and the aggregate predetermined residual
value of those vehicles, in each case in accordance with certain terms and
conditions as contained in the Manufacturer Program.

         Up to 20% of vehicles leased under the Lease Agreement and financed
with proceeds under the VFN will not have the benefit of a Manufacturer Program
(such vehicles, "Non-Program Vehicles").  Typically, Non-Program Vehicles are
purchased at a more favorable price or are specialty vehicles not eligible
under Manufacturer Programs.  Additionally, RCFC may purchase Non-Program
Vehicles from Approved Manufacturers which may not offer participation in their
Manufacturer Programs to Dollar and Thrifty.  At the conclusion of RCFC's use
of such vehicles, such Non-Program Vehicles will be disposed of in the
secondary vehicle market, principally through third-party vehicle auction
sites, wholesalers or dealers.

         The commercial paper notes issued by DTFC were initially rated A-1 by
Standard & Poor's, P-1 by Moody's, and D-1 by Duff & Phelps.  DTFC began its
initial sales of commercial paper on March 10, 1998, and has outstanding
approximately $50 million in commercial paper which matures no later than the
maximum term for any commercial paper which can be issued by DTFC, being 58
days.

         The descriptions contained herein of the various agreements relating
to the Commercial Paper Facility and Liquidity Facility are qualified in their
entirety by reference to the definitive agreements dated March 4, 1998,
included herewith as Exhibits 4.12 through 4.18.  In addition, the Company has
elected to include herewith certain exhibits in connection with the
Registration Statement on Form S-1, File No. 333-39661, filed with the
Securities and Exchange Commission which was declared effective on December 16,
1997.  Such exhibits, which are numbered 4.10 and 4.11, relate to the Company's
existing asset backed note program, specifically notes issued by RCFC in
December 1997 in the amount of $900 million, and also include information
relating to credit support furnished by Chrysler Corporation for such issuance
of notes.

       Each Lessee Grantor, RCFC, each other Financing Source and each

Vehicles (or, with respect to any Master Collateral Vehicle in an Existing
Fleet, to be the assignee of the first lienholder shown on the Certificates of
Title), in a representative capacity, as Master Collateral Agent for the
Beneficiaries.  The Master Collateral Agent agrees that all of its right, title
and interest in and to the Master Collateral shall be solely for the respective
benefit of each Beneficiary.

       Each Financing Source and each Beneficiary hereby directs the Master
Collateral Agent to execute and deliver as of the date set forth herein in its
capacity as Master Collateral Agent hereunder each Assignment Agreement
hereafter entered into by any of the Lessee Grantors or RCFC.

       (c)  Exclusions.  Notwithstanding the provisions of Section 2.1(a), it
is expressly acknowledged and agreed that the Lessee Grantor Master Collateral
does not and shall not in any event include any of the following items or types
of property:





                                      -16-
<PAGE>   21
              (i)  any Franchise Agreement, or any monies due or to become due
       to the applicable Lessee Grantor under any Franchise Agreement,
       including, without limitation, monies due or to become due to such
       Lessee Grantor on account of, relating to or in connection with (a)
       administrative fees, advertising fees and license or franchise fees
       under or in connection with any Franchise Agreements, (b) the grant,
       transfer, sale or other disposition, in whole or in part, of any
       Franchise Agreement, (c) the sale, lease or other offering by such
       Lessee Grantor of goods, supplies or products (excluding, however,
       Master Collateral Vehicles) to any Franchisee or the performance of
       services by such Lessee Grantor for any Franchisee, (d) insurance
       programs for Franchisees offered under or in connection with any
       Franchise Agreement, (e) credit card services provided in connection
       with any Franchise Agreement, and (f) promissory notes delivered
       pursuant to or in connection with any Franchise Agreement, or any other
       accounts, general intangibles, chattel paper, documents and instruments
       relating to or arising out of or in connection any Franchise Agreement;

              (ii)   any advertising or promotional allowances payable to any
       Lessee Grantor by any Manufacturer;

              (iii)  any monies due or to become due to any Lessee Grantor or
       any Franchisee or Affiliate of any Lessee Grantor from the retail rental
       of vehicles; or

              (iv)   any amounts payable by a Manufacturer to any Lessee
       Grantor which constitute manufacturer floor plan assistance.

Each Financing Source and each Beneficiary hereby disclaims and affirmatively
waives any right, title or interest in and to any of the foregoing items or
types of property under or pursuant to this Agreement.

       SECTION 2.2.  Designation of Beneficiaries; Beneficiaries' Rights
Limited.  Each of the Trustee, RCFC and any other Person who from time to time
executes a Financing Source and Beneficiary Supplement as a beneficiary is
hereby designated as a Beneficiary with respect to the Master Collateral
Vehicles designated on the Master Servicer's computer system as Master
Collateral Vehicles acquired by or financed with the proceeds advanced by the
Financing Sources relating to such Beneficiary or as otherwise provided in a
Financing Source and Beneficiary Supplement with respect to such Beneficiary
("Related Vehicles") and the other Master Collateral related thereto (the
"Related Master Collateral").  The designation of Related Vehicles with respect
to each Beneficiary on the Master Servicer's computer system shall be
considered prima facie evidence of such Beneficiary's rights with respect to
such Related Vehicles and the Related Master Collateral.  If at any time a
Beneficiary reasonably believes that such designation by the Master Servicer is
incorrect, it may dispute such designation by delivering a written notice to
the Master Collateral Agent setting forth its claim as to the correct
designation of its Related Vehicles (each a "Redesignation").  The Master
Collateral Agent shall, promptly upon receipt of such notice, distribute a copy
thereof to each Lessee Grantor, RCFC, each Financing Source and each
Beneficiary (other than the Beneficiary disputing the Master Servicer's
designation of Related





                                      -17-
<PAGE>   22
Vehicles).  Each such Financing Source and Beneficiary shall, within ten (10)
Business Days of receipt of such notice from the Master Collateral Agent,
notify the Master Collateral Agent in writing as to whether it consents to the
disputing Beneficiary's Redesignation.  If the Master Collateral Agent receives
written notice from each such Beneficiary and Financing Source containing its
consent to the disputing Beneficiary's Redesignation within the period set
forth above, it shall promptly notify the Master Servicer and the Master
Servicer shall effect such Redesignation.  Each Beneficiary shall be entitled
to the benefits of this Agreement only with respect to its Related Vehicles and
Related Master Collateral.  No Beneficiary shall have any interest in (i) any
Master Collateral Vehicle which is not a Related Vehicle as to such
Beneficiary, (ii) any funds in the Master Collateral Account that are proceeds
of any Master Collateral Vehicle which is not a Related Vehicle as to such
Beneficiary, (iii) rights under any Vehicle Disposition Program with respect to
any Master Collateral Vehicle which is not a Related Vehicle as to such
Beneficiary or (iv) any other Master Collateral which is not Related Master
Collateral as to such Beneficiary, in each case regardless of the time, order,
manner or nature of attachment or perfection of security interests in Master
Collateral Vehicles (including the giving of or failure to give notice of any
purchase money security interest or other notice, or the order of filing
financing statements), or any provision of the Uniform Commercial Code, the
federal Bankruptcy Code, or other applicable law.

       SECTION 2.3.  Redesignation of Beneficiaries.  RCFC, with respect to the
RCFC Master Collateral Vehicles, and each of the Lessee Grantors, with respect
to the Lessee Grantor Master Collateral Vehicles, may from time to time
refinance Master Collateral Vehicles related to a particular Financing Source
with proceeds from a different Financing Source.  In connection therewith, the
Master Servicer shall designate on its computer system the Financing Source the
proceeds of which are used to finance or refinance such Master Collateral
Vehicles, and, upon repayment of the Financing Source being refinanced, (x)
such Master Collateral Vehicles shall automatically constitute Related Vehicles
of the specified Beneficiary or Beneficiaries related to such refinancing
Financing Source, and (y) such Master Collateral Vehicles shall cease to be
Related Vehicles of the Beneficiary or Beneficiaries related to the refinanced
Financing Source.  In addition, the Master Servicer may from time to time
redesignate on its computer system, to a new Beneficiary related to a Financing
Source, one or more Master Collateral Vehicles that are Related Vehicles of
another Beneficiary related to such Financing Source, if such related Vehicles
have been designated to specific Beneficiaries.  Notwithstanding the foregoing,
the right of the Master Servicer to redesignate Master Collateral Vehicles that
will, after such a refinancing, cease to be Related Vehicles with respect to a
Financing Source or Beneficiary shall be subject to the conditions that
immediately after giving effect to such redesignation:

              (a)  no Default shall exist under the Financing Documents related
       to such Financing Source Beneficiary (provided, however, that the Master
       Servicer shall have the right to make such redesignation for the purpose
       of curing such a Default); and

              (b) Unless otherwise specified in the Financing Source and
       Beneficiary Supplement therefor, such Financing Source or Beneficiary
       shall have designated to it Related Vehicles with a collateral value (as
       determined, in accordance with the Financing Documents





                                      -18-
<PAGE>   23
       relating to the Financing Source or with respect to such Beneficiary, by
       the Person specified therein or, if no such Person is so specified, by
       the Master Servicer) not less than the minimum collateral value required
       in such Financing Documents to support the outstanding loans or
       securities issued under such Financing Documents.

Each designation of a Beneficiary pursuant to Section 2.2, and each
redesignation by the Master Servicer pursuant to this Section 2.3,  shall
automatically constitute a representation and warranty by the Master Servicer
for the benefit of the Beneficiary to which the Master Collateral Vehicle is
being designated or redesignated that (i) with respect to such a redesignation,
the conditions in Sections 2.3(a) and 2.3(b) have been met, (ii) with respect
to such a redesignation, the loans or securities of the original Financing
Source with respect to such refinanced Master Collateral Vehicles have been
repaid, and (iii) with respect to any such designation or redesignation, all
Related Vehicles of such Beneficiary constitute Eligible Vehicles under the
relevant Financing Documents.  Master Collateral Vehicles shall be redesignated
hereunder at their respective Net Book Values, calculated in accordance with
the Financing Documents relating to the Financing Source with respect to the
applicable Beneficiary.  Except as provided in Section 2.5(c), no Beneficiary
shall have any interest in any Master Collateral Vehicle or other Master
Collateral for which it is no longer designated as the Beneficiary, it being
understood that, subject to the satisfaction of the conditions set forth in
Sections 2.3(a) and 2.3(b) and repayment of the loans or securities of the
original Financing Source with respect to refinanced Master Collateral
Vehicles, any such redesignation shall automatically constitute a release by
such Beneficiary of any interest therein.

       SECTION 2.4.  Master Servicer's Fleet Report.  On or prior to the
Reporting Date, the Master Servicer shall furnish to the Master Collateral
Agent a report (which may be on diskette, magnetic tape or other electronic
medium acceptable to the Master Collateral Agent) substantially in the form of
Exhibit C ("Fleet Report"), showing for each Financing Source and each Related
Vehicle designated thereto, as of the last day of the immediately preceding
calendar month and after giving effect to the most recent redesignation of
Master Collateral Vehicles (i) the related Beneficiary in respect thereof, (ii)
whether such Related Vehicle is a Lessee Grantor Master Collateral Vehicle or
an RCFC Master Collateral Vehicle, (iii) the last eight digits of the vehicle
identification numbers with respect to such Related Vehicle, and (iv) the
Capitalized Cost and Net Book Value of such Related Vehicle (calculated in
accordance with the Financing Documents relating to the applicable Financing
Source).  The Master Collateral Agent shall make the Fleet Report available for
inspection by any Financing Source or Beneficiary at the Corporate Trust
Office, during normal business hours, upon such Financing Source or
Beneficiary's written request.  Each Fleet Report shall, upon delivery thereof
to the Master Collateral Agent, become Exhibit C hereto and shall replace and
supersede all prior Fleet Reports in such capacity.  The Master Collateral
Agent's sole responsibility with respect to such Fleet Report shall be
custodial.

       SECTION 2.5.  Master Collateral Account.  (a)  The Master Collateral
Agent shall establish and maintain, or cause to be established and maintained,
in the name of Master Collateral Agent for the benefit of the Beneficiaries,
one or more accounts (collectively, the "Master Collateral Account"), each
bearing a designation clearly indicating that the funds deposited therein





                                      -19-
<PAGE>   24
are held for the respective benefit of each Beneficiary and, in each case, as
to which sole dominion and control shall be vested in the Master Collateral
Agent.  The Master Collateral Account shall be maintained (i) with one or more
Qualified Institutions, or (ii) as  segregated trust accounts with the
corporate trust departments of depository institutions or trust companies
having corporate trust powers so long as each such institution has a credit
rating for its unsecured long-term debt not lower than investment grade by
Standard & Poor's.  If the Master Collateral Account (or any subaccount
thereof) is not maintained in accordance with the previous sentence, then
within ten (10) Business Days after a Responsible Officer has received written
notice from any related Beneficiary or Financing Source to establish a new
Master Collateral Account or subaccount thereof or has actual notice followed
by written confirmation (which confirmation the Master Collateral Agent shall
use its best efforts to obtain as soon as practicable at the request of the
related Beneficiary or Financing Source) of such fact, the Master Collateral
Agent shall establish a new Master Collateral Account (or a new subaccount)
which complies with such sentence and transfer into the new Master Collateral
Account (or subaccount) all funds from the non-qualifying Master Collateral
Account (or subaccount).  Initially, the Master Collateral Account will be
established with BOK and Bankers Trust Company, and both accounts together
shall be the Master Collateral Account.

       (b)  The Servicers and the Grantors shall direct all payments
representing (i) Disposition Proceeds, (ii) Guaranteed Payments and Repurchase
Payments under Vehicle Disposition Programs, (iii) Incentive Payments under
incentive programs, (iv) all payments under the Subleases and (v) all other
payments or other proceeds arising from the Master Collateral to be deposited
directly into the Master Collateral Account.  In the event that the Master
Servicer, any Servicer, RCFC or any Financing Source shall receive directly any
such payments or proceeds, including cash, securities, obligations or other
property, such Person shall accept in constructive trust for the Master
Collateral Agent, and hold and deposit into the Master Collateral Account at
Bankers Trust Company within two (2) Business Days of receipt thereof, any of
the foregoing payments or proceeds received directly by such Person in respect
of the Master Collateral, with the endorsement or other evidence of transfer of
such Person when necessary or appropriate.  Each Grantor shall designate the
Master Collateral Agent as loss payee on its physical damage and comprehensive
insurance policies on the Master Collateral Vehicles.  The Master Collateral
Agent shall, within one (1) Business Day after receipt thereof, notify the
Master Servicer when funds are deposited in the Master Collateral Account and
the amount of such funds and promptly thereafter, but in no event more than two
(2) Business Days after the receipt of such notice from the Master Collateral
Agent, the Master Servicer shall instruct the Master Collateral Agent in
writing (upon which instruction the Master Collateral Agent is entitled to
conclusively rely) with respect to funds received hereunder as to (i) the
aggregate amount thereof which represents payments or other proceeds arising
from the Related Vehicles and Related Master Collateral of each Beneficiary,
(ii) upon the occurrence and during the continuance of a Default and as needed
under clause (c) or (d) below or, in the sole judgment of the Master Servicer,
as otherwise needed, the dollar amount thereof that is derived from Lessee
Grantor Master Collateral and from RCFC Master Collateral,  (iii) the dollar
amount of Sublease payments, insurance payments, warranty payments and other
payments, as set forth below, in each case relating to Master Collateral
Vehicles, which, so long as no Default under the related Financing Documents
has occurred and is





                                      -20-
<PAGE>   25
continuing or would result therefrom, may be withdrawn from the Master
Collateral Account and distributed to the applicable Lessee Grantor, (iv) the
dollar amount of funds not constituting Master Collateral (which may be
distributed at any time to the Person entitled thereto), and (v) any additional
information provided by the Master Servicer pursuant to and in accordance with
Section 24.4(a) of the Lease.  The Master Collateral Agent shall promptly after
receipt of instructions from the Master Servicer (upon which instructions the
Master Collateral Agent may conclusively rely), but in no event later than ten
(10) days after any such payments or proceeds are first received by RCFC, a
Lessee Grantor, the Trustee or the Master Collateral Agent (including by
deposit in the Master Collateral Account), distribute or cause to be
distributed to each Beneficiary, in an amount specified by the Master Servicer
as provided above, the funds in the Master Collateral Account representing
payments or other proceeds arising from the Related Vehicles and Related Master
Collateral of such Beneficiary, to an account previously specified in writing
by such Beneficiary to the Master Collateral Agent; provided, however, that the
Master Servicer shall not direct the Master Collateral Agent to so remit any
amount in respect of Lessee Grantor Master Collateral or RCFC Master
Collateral, as the case may be, that would exceed the amount required to pay
all amounts owing to such Beneficiary or to the Financing Source related to
such Beneficiary by RCFC or the Lessee Grantors, respectively; and provided,
further, that so long as no Default has occurred and is continuing or would
result therefrom, all funds representing (x) payments under a Sublease or under
any contract, agreement, guaranty, insurance, warranty, instrument or
certificate entered into by or delivered to a Lessee Grantor, in connection
with a Sublease, or (y) payments under insurance policies or warranties payable
by reason of loss or damage to, or otherwise with respect to, any of the Master
Collateral Vehicles, shall promptly be distributed to the applicable Lessee
Grantor, to an account previously specified in writing by such Lessee Grantor,
or as the applicable Lessee Grantor shall otherwise direct.  Notwithstanding
the foregoing, the Master Servicer may at any time instruct the Master
Collateral Agent to release any funds not constituting Master Collateral to the
Person entitled thereto.

       (c)  At such time as no further distributions from a Lessee Grantor to a
Financing Source, pursuant to the Financing Documents, are required or will be
required to be made to a Beneficiary in accordance with Section 2.5(b), and any
applicable bankruptcy preference period has expired, all remaining funds
deposited in respect of Lessee Grantor Master Collateral in the Master
Collateral Account and allocated to such Beneficiary shall promptly be
distributed to such Lessee Grantor upon the written direction of the Master
Servicer.

       (d)  At such time as no further distributions from RCFC to a Financing
Source, pursuant to the Financing Documents, are required or will be required
to be made to a Beneficiary in accordance with Section 2.5(b), and any
applicable bankruptcy preference period has expired, all remaining funds
deposited in respect of RCFC Master Collateral in the Master Collateral Account
and allocated to such Beneficiary shall promptly be distributed to RCFC upon
the written direction of the Master Servicer.

       (e)  If at any time the Master Collateral Agent, a Servicer or the
Master Servicer shall receive any funds to which it is not entitled pursuant to
the provisions of this Agreement, such Servicer or the Master Servicer shall so
advise the Master Collateral Agent (upon which advice





                                      -21-
<PAGE>   26
the Master Collateral Agent may conclusively rely) and the Master Collateral
Agent or such Servicer or the Master Servicer, as the case may be, shall
forthwith take reasonable steps to ensure that such funds are remitted to the
Person so entitled thereto, such remittance to be made promptly after the
determination thereof and if by the Master Collateral Agent, as directed in
writing by the Master Servicer.

       (f)  The Master Servicer shall instruct (upon which instruction the
Master Collateral Agent may conclusively rely) the Master Collateral Agent in
writing to invest funds on deposit in the Master Collateral Account in
Permitted Investments.  If the Master Collateral Agent does not receive
instructions from the Master Servicer prior to 11:00 a.m., New York City time,
on any day as to the distribution or investment of any funds in the Master
Collateral Account, then the Master Collateral Agent shall invest such funds in
Permitted Investments set forth in Exhibit H, as the same may be from time to
time revised by the Master Servicer upon three (3) Business Days' prior written
notice to the Master Collateral Agent (the "Investment Standing Instruction").
All such investments shall be redeemable or mature on the next Business Day.
Neither the Master Servicer nor the Master Collateral Agent shall be
responsible for any losses incurred on any investments made pursuant to and in
accordance with this paragraph (f).  The Master Collateral Agent shall, in
accordance herewith, be entitled to rely upon the most recent Investment
Standing Instruction or other written instruction received pursuant to this
Section 2.5(f).

       SECTION 2.6.  Certificates of Title.  Each Servicer shall hold in trust,
as agent of and as custodian for the Master Collateral Agent, all Certificates
of Title for Master Collateral Vehicles leased by such Servicer under a Lease.
The applicable Servicer shall (i) hold all such Certificates of Title under
lock and key, in a safe fireproof location at one or more of the offices
specified in Exhibit D (as the same may be from time to time revised by the
applicable Servicer upon thirty (30) days' prior written notice to the parties
hereto), and (ii) not release or surrender any Certificate of Title except in
accordance with this Agreement (and in any event not release or surrender any
of the Certificates of Title other than Certificates of Title as to which the
Lien of the Master Collateral Agent has been released in accordance with this
Agreement).  The applicable Servicer shall cause the Certificates of Title with
respect to each Master Collateral Vehicle leased by it under a Lease (other
than a Master Collateral Vehicle included in an Existing Fleet) to show the
applicable Lessee Grantor, and with respect to each RCFC Master Collateral
Vehicle to show RCFC, as the registered owner thereof and to show Bankers Trust
Company, as agent (or as otherwise required under governing law to perfect the
Lien of the Master Collateral Agent), as the first lienholder at the address
referred to in the next sentence.  The Master Collateral Agent has established
a post office box in Tulsa, Oklahoma at an address specified in Section 5.2
hereof, to be used from and after the date hereof as its exclusive address as
first lienholder noted on the Certificates of Title.  The Master Collateral
Agent shall, on a semi-weekly basis, forward to each Lessee Grantor at its
address set forth in Section 5.2 hereof, all Certificates of Title received at
such post office box address titled in the name of such Lessee Grantor, all
Certificates of Title received at such post office box address titled in the
name of RCFC.

       SECTION 2.7.  Notation of Liens; Release of Collateral.  (a)  The Master
Collateral Agent hereby grants to each Servicer a limited power of attorney,
with full power of substitution,





                                      -22-
<PAGE>   27
to take any and all actions, in the name of the Master Collateral Agent, (i) to
note the Master Collateral Agent as the holder of a first lien on the
Certificates of Title, and/or otherwise ensure that the first Lien shown on any
and all Certificates of Title (other than any Certificates of Title relating to
an Existing Fleet) is in the name of the Master Collateral Agent, (ii) to
release the Master Collateral Agent's Lien on any Certificate of Title in
connection with the sale or disposition of the related Master Collateral
Vehicle permitted pursuant to the provisions of the Financing Documents
relating to such Master Collateral Vehicle; and (iii) to release the Master
Collateral Agent's Lien on any Certificate of Title with respect to any Master
Collateral Vehicle which is not a Related Vehicle with respect to any
Beneficiary or with respect to which all obligations under the Financing
Documents to each related Beneficiary have been satisfied in full (and any
applicable bankruptcy preference period has expired).  Nothing in this
Agreement shall be construed as authorization from the Master Collateral Agent
to any Servicer to release any Lien on any Certificate of Title except upon
compliance with this Agreement.

       (b)  Each Beneficiary may cause the Master Collateral Agent to terminate
the limited power of attorney referred to in Section 2.7(a) (including the
related power granted under Section 2.8) with respect to such Beneficiary's
Related Vehicles after the occurrence, and during the continuance, of a Default
(after giving effect to any cure period or grace period) under the Financing
Documents relating to the Financing Source with respect to such Beneficiary by
giving written notice to such effect to the applicable Servicer and the Master
Collateral Agent.  The Master Collateral Agent agrees that upon receipt of any
such notice it shall promptly terminate such power of attorney with respect to
such Beneficiary's Related Vehicles by giving written notice to such effect to
the applicable Servicer.  The power of attorney referred to in Section 2.7(a)
(including the related power granted under Section 2.8) will also terminate
following the resignation or removal of the Master Collateral Agent pursuant to
Section 4.5.  The Master Collateral Agent will follow the direction (upon which
direction the Master Collateral Agent may conclusively rely) of the applicable
Servicer to release liens on Master Collateral Vehicles unless either a
contrary direction is received from a Financing Source or Beneficiary or the
Financing Documents require direction to be given by another party.  In
connection with any release permitted under this Section 2.7, the Master
Collateral Agent and each Beneficiary agrees to execute such further documents,
if any, as may be reasonably requested by the applicable Servicer to effect
such release.

       SECTION 2.8.  Power of Attorney.  To further evidence the limited power
of attorney referred to in Section 2.7, the Master Collateral Agent agrees that
upon request of the Servicer it will execute a separate power of attorney
substantially in the form of Exhibit E.

allocated to such Beneficiary to support the outstanding loans or securities
issued or obligations arising under such Financing Documents, (iii) direct
payments and other proceeds due under the Vehicle Disposition Programs and

Sections 2.5(b) through 2.5(d) in accordance with the related Financing
Documents, (vi) execute and deliver, for the benefit of the Beneficiaries, any
and all documents with respect to the Master Collateral Vehicles and the

designated by it hereunder, to do any and all things in connection with its
servicing and administration duties which it may deem necessary or desirable to
accomplish such servicing and administration duties and which does not
materially adversely affect the interests of any Beneficiary, unless otherwise
prohibited by applicable Financing Documents or applicable law and regulations.
Nothing in this Agreement shall at any time prevent the Master Servicer from in
good faith taking any action to assure that its systems and records relating to
the Master Collateral Vehicles and the Financing Sources are at all times
accurate.

       SECTION 3.3.  The Master Servicer Not to Resign.  Without the prior
written consent of the Master Collateral Agent, each of the Financing Sources
and Beneficiaries, and the Rating





                                      -24-
<PAGE>   29
Agencies, the Master Servicer shall not resign from the obligations and duties
imposed on it hereunder.

       SECTION 3.4.  Servicing Rights of Master Collateral Agent.  If the
Master Servicer resigns or shall fail to perform any of its obligations
hereunder, which failure adversely affects one or more Beneficiaries to a
material degree, the Master Collateral Agent, at the direction and at the
expense of the Beneficiaries so adversely affected thereby, shall take such
action or cause such action to be taken (pursuant to Section 4.1(d)), to
perform such obligations as shall be so directed by such Beneficiaries,
whereupon the Master Collateral Agent shall have full right and authority to
take or cause to be taken such action so directed, provided, that, such action
or direction is permitted by the related Financing Documents or this Agreement
and that the Master Collateral Agent is indemnified to its satisfaction in
connection therewith.

       SECTION 3.5.  Incumbency Certificate.  With the delivery of this Master
Collateral Agency Agreement and from time to time thereafter, each Servicer,
RCFC and the Master Servicer shall furnish to the Master Collateral Agent a
certificate (each, an "Incumbency Certificate") certifying as to the incumbency
and specimen signatures of officers of each Servicer, RCFC and the Master
Servicer, respectively (the "Authorized Agents"), authorized to act, and to
give instructions and notices, on behalf of each such Servicer, RCFC and the
Master Servicer, respectively, hereunder.  Until the Master Collateral Agent
receives a subsequent Incumbency Certificate, the Master Collateral Agent shall
be entitled to rely on the last such Incumbency Certificate delivered to it for
purposes of determining the Authorized Agents.


                                   ARTICLE IV

                          THE MASTER COLLATERAL AGENT

       SECTION 4.1.  Appointment.  (a)  Each Financing Source and each
Beneficiary, by its execution of this Agreement, appoints Bankers Trust Company
as the Master Collateral Agent under and for purposes of this Agreement.  Each
Financing Source and each Beneficiary authorizes the Master Collateral Agent to
act on behalf of such Financing Source and Beneficiary under this Agreement
and, in the absence of other written instructions from a Beneficiary with
respect to its Related Vehicles and Related Master Collateral as may be
received from time to time by the Master Collateral Agent (with respect to
which the Master Collateral Agent agrees that it will comply), subject to the
other provisions of this Article IV, to exercise such powers hereunder as are
specifically delegated to or required of the Master Collateral Agent by the
terms hereof and to exercise such powers as are provided to each Financing
Source and Beneficiary with respect to its Related Vehicles and other Related
Master Collateral under the related Financing Documents, along with such powers
as may be reasonably incidental thereto.  The Master Collateral Agent is hereby
irrevocably appointed the true and lawful attorney-in-fact of each of the
Beneficiaries, in its name and stead, for such purposes as are necessary or
desirable to effectuate the provisions of this Agreement, including, without
limitation, in exercising remedies





                                      -25-
<PAGE>   30
upon or otherwise dealing with the Master Collateral.  Each such power of
attorney is irrevocable and coupled with an interest.

       (b)  If and whenever a Default shall have occurred and be continuing,
the Master Collateral Agent may and, at the direction of the applicable related
Beneficiary (as provided in the next succeeding sentence) shall, exercise from
time to time any rights and remedies available to it under applicable law or
any Financing Document.  If any Beneficiary notifies the Master Collateral
Agent in writing that it or the Master Collateral Agent has the right to act
with respect to the Beneficiary's related Master Collateral pursuant to its
related Financing Documents or pursuant to the UCC as in effect in the
applicable jurisdiction, then the Master Collateral Agent, if it has been
indemnified to its satisfaction and is legally able to do so, shall exercise or
arrange for the exercise of any and all rights, remedies, powers and privileges
available to such Beneficiary or the Master Collateral Agent with respect to
the Beneficiary's related Master Collateral to the extent and in the manner
directed by such Beneficiary, at such Beneficiary's expense and subject to the
other provisions of this Agreement (including, without limitation, Section
4.4(g)), as permitted under the related Financing Documents and under relevant
law and regulations, including, without limitation, the transmission of notices
of default, repossession of Related Vehicles, and the institution of legal or
administrative actions or proceedings.  Each of the Lessee Grantors, RCFC, the
Beneficiaries and the Financing Sources agrees that the Master Collateral Agent
may exercise such rights, remedies, powers and privileges assigned to it or in
lieu of a Beneficiary in accordance with the preceding sentence and agrees that
the Grantors shall reimburse the Master Collateral Agent for such enforcement
expenses only to the same extent that they would be obligated to reimburse the
Master Collateral Agent or the applicable Beneficiary for such enforcement
expenses pursuant to the related Financing Documents.

       (c)  Instructions given to the Master Collateral Agent by any
Beneficiary shall comply (and delivery of any such instructions by a
Beneficiary to the Master Collateral Agent shall be deemed to be a
representation and warranty by such Beneficiary that such instructions comply)
with the Financing Documents of such Beneficiary and with applicable law and
regulations.

       (d)  The Master Collateral Agent may at any time delegate any duties or
obligations hereunder (including, but not limited to, any duties or obligations
arising pursuant to Section 3.4 or 4.1(b) hereof) to any Person (other than,
with respect to any actions as agent of the Beneficiaries as secured parties,
any Person with any other interest in the Master Collateral) who agrees to
conduct such duties in accordance with the terms hereof.  Any such delegation
shall not constitute a resignation within the meaning of Section 4.5 hereof and
the Master Collateral Agent shall not be liable for the negligence, acts or
omissions of such Persons so long as such Persons are selected with due care.
If any such delegation occurs, notification of the identity of such Person
shall be given to the Servicer, the Beneficiaries and the Rating Agencies.

       (e)  If, at the time a Default exists under the Financing Documents
related to a Beneficiary, the Master Collateral Agent shall default in its
obligation or for any reason be unwilling or legally unable to exercise the
rights, remedies, powers or privileges with respect to the Related Master
Collateral of a Beneficiary in accordance with the direction of such
Beneficiary (including any





                                      -26-
<PAGE>   31
rights under Section 3.4 or 4.1(b)), the Master Collateral Agent shall, upon
the written request of such Beneficiary, assign (without recourse to the Master
Collateral Agent) to such Beneficiary the Master Collateral Agent's security
interest in such Beneficiary's Master Collateral and shall prepare and execute
those instruments and documents necessary to effectuate such assignment
(including, if necessary, the execution of documents necessary to change the
name of the first lienholder on Certificates of Title for such Beneficiary's
Related Vehicles to such Beneficiary or its agent or assignee).

       (f)  Bankers Trust Company, in its individual or in any other capacity
(including as Trustee), may be a Beneficiary hereunder and as such shall be
entitled to all of the protections and rights of a Beneficiary under this
Agreement without regard to its capacity as Master Collateral Agent hereunder.

       (g)  Within three (3) Business Days of receipt by the Master Collateral
Agent from a Manufacturer of any material information pertaining to payments of
Disposition Proceeds, Guaranteed Payments, Repurchase Payments, or Incentive
Payments, or any payments arising under the Subleases, made or to be made to
the Master Collateral Account, the Master Collateral Agent shall provide such
information to the Master Servicer.

       SECTION 4.2.  Representations.  Bankers Trust Company hereby represents
and warrants that (i) it has all requisite corporate power and authority to
enter into and perform its obligations under this Agreement and (ii) the
execution, delivery and performance by it of this Agreement have been duly
authorized by all necessary corporate action on its part, and this Agreement is
the legal, valid and binding obligation of Bankers Trust Company, enforceable
against it in accordance with its terms, except as such enforcement may be
limited by applicable bankruptcy, insolvency, moratorium or similar laws
affecting creditors' rights generally and by the application of equitable
principles.

       SECTION 4.3.  Exculpatory Provisions.  The Master Collateral Agent makes
no representations as to the value or condition of the Master Collateral or any
part thereof, the status or designation of any Master Collateral Vehicle as a
Related Vehicle to any Beneficiary pursuant to Section 2.2 hereof, as to the
title of any Lessee Grantor or RCFC thereto, as to the protection afforded by
this Agreement, as to the Fleet Report, any statements, representations or
warranties made by any other Person in or in connection with this Agreement or
any Financing Document, as to the validity, execution (except its own
execution), enforceability of this Agreement (except as against itself),
priority, perfection, legality or sufficiency of this Agreement or any
Financing Document or any documents or instruments referred to therein, or the
sufficiency or effectiveness or perfection or priority of any Lien on any
collateral described in this Agreement, or as to the validity or collectibility
of any obligation contemplated by this Agreement, and the Master Collateral
Agent shall incur no liability or responsibility in respect of any such
matters; provided, however, that the Master Collateral Agent shall not be
relieved from liability for its own gross negligence or willful misconduct.
The Master Collateral Agent shall not be charged with knowledge of the contents
of any Fleet Report or any Financing Document.  The Master Collateral Agent
shall not be responsible for insuring the Master Collateral.  Any reference
herein





                                      -27-
<PAGE>   32
to actual knowledge of the Master Collateral Agent shall mean actual knowledge
of a Responsible Officer of the Master Collateral Agent assigned to and working
in its Corporate Trust Office.

       SECTION 4.4.  Limitations on Powers and Duties of the Master Collateral
Agent.  (a)  The Master Collateral Agent undertakes to perform only the duties
expressly set forth herein and no implied duties shall be read into this
Agreement.

       (b)  The Master Collateral Agent may exercise the rights and powers
granted to it by this Agreement, together with such powers as are reasonably
incidental thereto, but only pursuant to the terms of this Agreement.

       (c)  The Master Collateral Agent's duty of care shall be solely to deal
with the Master Collateral as it would with property of its own.

       (d)  The Master Collateral Agent shall have no authority to grant,
convey or assign the Certificates of Title or change the notation of a security
interest thereon or deal with the Certificates of Title in any way except as
expressly provided herein.

       (e)  The Master Collateral Agent shall have no liability or
responsibility for (i) any release of Master Collateral or other act or
omission by a Servicer pursuant to Section 2.7 or 2.8, (ii) any act of a
Servicer taken in its own name or the name of the Master Collateral Agent, or
(iii) custody of any Certificates of Title not delivered to it and required to
be held by it in connection with this Agreement.

       (f)  The Master Collateral Agent shall have no duty to calculate,
compute or verify, and shall not be held in any manner responsible for the
content of the Fleet Report, except to verify that the certificate filed
therewith conforms to the form of Exhibit C.

       (g)  Except as required by the specific terms of this Agreement, the
Master Collateral Agent shall have no duty to exercise or to refrain from
exercising any right, power, remedy or privilege granted to it hereby, or to
take any affirmative action or refrain from taking any affirmative action
hereunder, unless directed to do so by Beneficiaries specified herein as being
entitled to direct the Master Collateral Agent hereunder (and shall be fully
protected in acting or refraining from acting pursuant to or in accordance with
such directions, which shall be binding on each Lessee Grantor, RCFC, and each
of the Financing Sources and Beneficiaries).  Notwithstanding anything herein
to the contrary, the Master Collateral Agent shall not be required to take any
action that is or may be contrary to law or to the terms of this Agreement, any
Financing Document or any other agreement or instrument relating to the Master
Collateral, or which might subject it or any of its directors, officers,
employees or agents to personal or financial liability.  If any indemnity
provided should become, in the determination of the Master Collateral Agent,
inadequate, the Master Collateral Agent may call for additional indemnity and
cease to act until and unless such additional indemnity is given.





                                      -28-
<PAGE>   33
       (h)  The Master Collateral Agent may, in its sole discretion, retain
counsel, agents, independent accountants and other experts selected by it and
may act in reliance upon the advice of such counsel, independent accountants
and other experts concerning all matters pertaining to the agencies hereby
created and its duties hereunder, and shall be held harmless and shall not be
liable for any action taken or omitted to be taken by it in good faith in
reliance upon or in accordance with the statements and advice of such counsel,
agents, accountants and other experts.  The Master Collateral Agent shall have
the right at any time to seek instructions concerning its duties and actions
under this Agreement from any court of competent jurisdiction.

       (i)  If the Master Collateral Agent receives unclear or conflicting
instructions, it shall be entitled to refrain from taking action until clear or
non-conflicting instructions are received, but shall inform the instructing
party or parties promptly of its decision to refrain from taking such action.
Without limiting the foregoing, in the event that the Master Collateral Agent
receives unclear or conflicting instructions from Beneficiaries hereunder or
there is any other disagreement between the other parties hereto resulting in
adverse claims and demands being made in connection with the Master Collateral,
or in the event that the Master Collateral Agent in good faith is in doubt as
to what action it should take hereunder, the Master Collateral Agent shall be
entitled to retain the Master Collateral until the Master Collateral Agent
shall have received (i) a final nonappealable order of a court of competent
jurisdiction directing delivery of the Master Collateral or (ii) a written
agreement executed by all the other parties hereto directing delivery of the
Master Collateral in which event the Master Collateral Agent shall disburse the
Master Collateral in accordance with such order or agreement.  Any court order
shall be accompanied by a legal opinion by counsel for the presenting party
satisfactory to the Master Collateral Agent to the effect that such order is
final and nonappealable.

       (j)  The Master Collateral Agent shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants
or conditions of this Agreement, any Financing Document or any other agreements
or instruments relating to the Master Collateral on the part of any party
hereto or thereto or to inspect any books and records relating to the Master
Collateral.

       (k)  The Master Collateral Agent shall be entitled to rely on any
communication, certificate, instrument, opinion, report, notice, paper or other
document reasonably believed by it to be genuine and correct and to have been
signed, given or sent by the proper Person or Persons.  The Master Collateral
Agent shall be entitled to assume that no Default shall have occurred and be
continuing and that the Master Collateral Account, and any funds on deposit in
or to the credit of such Master Collateral Account, are not subject to any
writ, order, judgment, warrant of attachment, execution or similar process
(collectively a "writ"), unless (i) a Responsible Officer of the Master
Collateral Agent has actual knowledge thereof or (ii) the Master Collateral
Agent has received written notice from a Lessee Grantor, RCFC, a Servicer, the
Master Servicer, a Beneficiary or a Financing Source that such a Default has
occurred or such writ has been issued and, in each case, continues to be in
effect, which notice specifies the nature thereof.





                                      -29-
<PAGE>   34
       (l)  Bankers Trust Company, in its individual capacity, may accept
deposits from, lend money to and generally engage in any kind of business with
any Lessee Grantor, any Financing Source, any Manufacturer and their respective
affiliates as if it were not the agent of the Beneficiaries or the Financing
Sources.

       (m)  The Master Collateral Agent shall not be accountable for the use or
application by any person of disbursements properly made by the Master
Collateral Agent in conformity with the provisions of this Agreement.

       (n)  The Master Collateral Agent may exercise any of its duties
hereunder by or through agents or employees in accordance with Section 4.1(d).
The possession of the Master Collateral by such agents or employees shall be
deemed to be the possession of the Master Collateral Agent.  No provision of
this Agreement shall require the Master Collateral Agent to expend or risk its
own funds or otherwise incur any financial or other liability in the
performance of any duties hereunder or in the exercise of any rights and powers
hereunder unless the Master Collateral Agent is provided with an indemnity from
one or more Beneficiaries, satisfactory to the Master Collateral Agent in its
sole discretion.

       SECTION 4.5.  Resignation and Removal of Master Collateral Agent.  (a)
The Master Collateral Agent may, at any time with or without cause by giving
forty-five (45) days' prior written notice to the Master Servicer, RCFC, the
Financing Sources and the Beneficiaries, resign and be discharged of its
responsibilities hereunder created, such resignation to become effective upon
the appointment by the Master Servicer and RCFC of a successor Master
Collateral Agent with the approval of the Required Beneficiaries (which
approval shall not be unreasonably withheld) and the acceptance of such
appointment by such successor Master Collateral Agent or the appointment
thereof by a court of competent jurisdiction (as and to the extent provided in
the related Financing Documents). The Master Servicer and RCFC shall, promptly
upon receipt thereof, provide a copy of the notice from the Master Collateral
Agent referred to in the preceding sentence to each Rating Agency.  The Master
Collateral Agent may be removed by the Master Servicer or RCFC at any time
(with or without cause) upon thirty (30) days' written notice by the Master
Servicer or RCFC, as the case may be, to the Master Collateral Agent and each
of the Rating Agencies, and the approval of the successor Master Collateral
Agent by the Required Beneficiaries, which approval will not be unreasonably
withheld; provided, however, that if either the Master Servicer or RCFC is in
default under this Agreement or any Financing Document and such default has a
material adverse effect on the Beneficiaries, then so long as such default
continues, the right of the Master Servicer or RCFC, as applicable, to remove
the Master Collateral Agent shall cease and the non-defaulting party shall
have, or if both the Master Servicer and RCFC are then in default, then the
Required Beneficiaries shall have the right to remove the Master Collateral
Agent (with or without cause) upon thirty (30) days' written notice to the
Master Servicer RCFC, the Master Collateral Agent and each of the Rating
Agencies; provided, further, that no removal of the Master Collateral Agent
shall be effective until the appointment of a successor Master Collateral Agent
and acceptance of such appointment by such Master Collateral Agent.  Any
removed Master Collateral Agent shall be entitled to its reasonable fees and
expenses to the date the successor Master Collateral Agent assumes the Master
Collateral





                                      -30-
<PAGE>   35
Agent's duties hereunder.  The indemnification of Section 4.10 shall survive
the termination of the other provisions of this Agreement as to the predecessor
Master Collateral Agent.  If no successor Master Collateral Agent shall be
appointed and approved within thirty (30) days from the date of the giving of
the aforesaid notice of resignation or within thirty (30) days from the date of
such notice of removal, the Master Collateral Agent, on behalf of the Master
Servicer and RCFC, each Financing Source and each Beneficiary may appoint a
successor Master Collateral Agent to act until such time, if any, as a
successor Master Collateral Agent shall be appointed as above provided.  If a
successor Master Collateral Agent does not take office within thirty (30) days
after the retiring Master Collateral Agent resigns or is removed, the retiring
Master Collateral Agent, on behalf of the Master Servicer and RCFC, each
Financing Source and each Beneficiary may petition any court of competent
jurisdiction for the appointment of a successor Master Collateral Agent.  Any
successor Master Collateral Agent so appointed by such court shall immediately
without further act supersede any predecessor Master Collateral Agent.  Upon
the appointment of a successor Master Collateral Agent hereunder, the
predecessor Master Collateral Agent shall be discharged of and from any and all
further obligations arising in connection with this Agreement.

       (b)  The appointment and designation referred to in Section 4.5(a)
shall, after any required filing, be full evidence of the right and authority
to make the same and of all the facts therein recited, and this Agreement shall
vest in such successor Master Collateral Agent, without any further act, deed
or conveyance, all of the estate and title of its predecessors and upon such
filing for record the successor Master Collateral Agent shall become fully
vested with all the estates, properties, rights, powers, duties, authority and
title of its predecessors; but any predecessor Master Collateral Agent shall,
nevertheless, on payment of its charges and on the written request of the
Required Beneficiaries, the Master Servicer, RCFC or any successor Master
Collateral Agent empowered to act as such at the time any such request is made,
execute and deliver an instrument without recourse or representation

Lessee Grantors, jointly and severally, shall reimburse each Beneficiary for
any payments made by such Beneficiary to the Master Collateral Agent or any
such officers, employees, directors or agents for any of the foregoing;
provided, however, that the Lessee Grantors shall not be liable for the payment

resignation or removal of the Master Collateral Agent.

questions arising under this Agreement which shall not be inconsistent with the
provisions of this Master Collateral Agency Agreement or any other such Related

Supplement by such additional Financing Source or Beneficiary, the Master
Collateral Agent, the Servicer and each Lessee Grantor.  The Master Servicer
shall give the Rating Agencies prior written notice of any amendment,
supplement, waiver or modification of this Agreement.  The Master Collateral

compliance with and is not prohibited by this Agreement and the Financing
Documents.  Upon execution of a Financing Source and Beneficiary Supplement,
the Master Servicer shall furnish a copy thereof to the other parties hereto.

       SECTION 5.8.  Effectiveness.  This Agreement shall become effective on
the execution and delivery hereof and shall remain in effect until no amounts
are owed to any Financing Source under any Financing Document and no
Beneficiary or Financing Source shall have any claim on the Master Collateral.

       SECTION 5.9.  Termination of Beneficiary.  Upon receipt by the Master
Collateral Agent of a notice from a Beneficiary to the effect that (i) (A) such
Beneficiary then has no Related Vehicles hereunder, no amounts are then owing
to the related Financing Source under its Financing Documents and such
Financing Documents have been terminated and are of no further force or effect
or (B) the Master Collateral Agent's security interest has been reassigned to
such Beneficiary pursuant to Section 4.1(e) and (ii) such Beneficiary has
elected to terminate this Agreement, this Agreement shall terminate as to such
Beneficiary.

       SECTION 5.10.  Termination of this Agreement.  At any time that there
are no Beneficiaries, the Lessee Grantors and RCFC may terminate this Agreement
upon notice to the Master Collateral Agent, and the Master Collateral Agent
shall take all actions reasonably requested by the Lessee Grantors and RCFC, at
the joint and several expense of the Lessee Grantors, to evidence the
termination of this Agreement and the Master Collateral Agent's interest in the
Master Collateral, including, without limitation, execute such documents and
instruments as RCFC or any Lessee Grantor may prepare and reasonably request to
be executed by the Master Collateral Agent in connection with such
reassignment; provided, however, that Sections 4.3, 4.4(a), (c), and (e)

shall survive the termination of this Agreement.

       SECTION 5.11.  Assignment by Financing Sources.  Each Financing Source

Beneficiary or Beneficiaries all of its rights and interests under this

       SECTION 5.12.  RCFC Related Documents.  To the extent that this
Agreement affects the secured parties under RCFC's Financing Documents, it
shall be considered a Related Document (as defined in RCFC's Financing
Documents) for all purposes except voting provisions.

       SECTION 5.13.  No Bankruptcy Petition Against Financing Sources.  The
Master Collateral Agent hereby covenants and agrees that, prior to the date
which is one year and one day after the payment in full of the latest maturing
debt security issued by a Financing Source, it will not institute against, or
join with any other Person in instituting against, such Financing Source, any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,
or other proceedings under any Federal or state bankruptcy or similar law;
provided, however, that nothing in this Section 5.13 shall constitute a waiver
of any right to indemnification, reimbursement or other payment from any
Financing Source or Beneficiary pursuant to this Agreement; provided, further,
that this Section 5.13 shall only be effective with respect to a Financing
Source for which the related Financing Documents contain a "no bankruptcy
petition" provision similar to this Section 5.13.  In the event that the Master
Collateral Agent takes action in violation of this Section 5.13, each affected
Financing Source agrees that it shall file an answer with the bankruptcy court
or otherwise properly contest the filing of such a petition by the Master
Collateral Agent against such Financing Source or the commencement of such
action and raise the defense that the Master Collateral Agent has agreed in
writing not to take such action and should be estopped and precluded therefrom

The provisions of this Section 5.13 shall survive the termination of this
Agreement, and the resignation or removal of the Master Collateral Agent.

                   LETTERS OF CREDIT; REIMBURSEMENT OBLIGATION

     Section 2.1. Issuance of Chrysler Letters of Credit; Reduction Amounts. (a)
Chrysler hereby agrees, on the terms and subject to the conditions hereinafter
set forth, to execute and deliver (i) to the Series 1997-1 Letter of Credit
Provider the Chrysler Series 1997-1 Support Letter of Credit in an initial
amount not exceeding $50,000,000 (such amount less the reductions (if any)

Credit or that the CP Program continues beyond December 23, 2002 (such excess,
the "Remaining Amount"), to the CP Program Letter of Credit Provider a letter of
credit in form and substance substantially similar to the Chrysler Series 1997-1
Support Letter of Credit (the "CP Program Support Letter of Credit" and,
together with the Chrysler Series 1997-1 Support Letter of Credit, the "Chrysler
Support Letters of Credit") (except that such letter of credit shall also
provide for reimbursement of the CP Program Letter of Credit Provider for
"liquidity drawings" made upon the CP Program Letter of Credit Provider) in a
stated amount equal to the Remaining Amount, which letter of credit shall be
reasonably acceptable to the CP Program Letter of Credit Provider. In the event
the letter of credit described in the preceding clause (ii) is to be delivered
to the CP Program Letter of Credit Provider by Chrysler, the parties hereto
agree to use their best efforts to negotiate a supplement to this Agreement that
would contain terms and conditions governing such letter of credit that are in
form and substance substantially similar to the terms and conditions set forth
herein governing the Chrysler Series 1997-1 Support Letter of Credit (except
that such supplement shall contain terms providing for reimbursement of
"liquidity" draws by Dollar Thrifty Funding over a period of up to 18 months,
the selection of interest periods and rates with respect to such drawings, the
apportionment of termination draws between "liquidity" draws and "credit" draws,
and the ability of the trustee with respect to the CP Program (or its agent) to
convert "liquidity" drawings to "credit" drawings all of which terms shall be
substantially similar to those governing any Enhancement Letter of Credit),
which supplement shall be reasonably acceptable to the CP Program Letter of
Credit Provider and the parties hereto. In the event the net cash proceeds
received by DTAG pursuant to the exercise by the underwriters and managers of
the Equity Offerings of their options (the "Over-Allotment Options") pursuant to
Section 3 of the Underwriting Agreement, dated December 16, 1997, among DTAG,
Chrysler, Credit Suisse First Boston Corp., Goldman, Sachs & Co., J.P. Morgan
Securities Inc. and Smith Barney, Inc. to purchase additional shares of Common
Stock to cover over-allotments exceeds $10,000,000, the commitment of Chrysler
hereunder to provide a letter of credit or letters of credit in an aggregate
stated amount of $50,000,000 (the "Chrysler Support Commitment") shall be
reduced, on the Closing Date (with respect to Over-Allotment Options exercised
on or prior to the Closing Date) or (with respect to Over-Allotment Options
exercised after the Closing Date), not later than 10 business days after the
earlier of (i) the exercise of all of the remaining Over-Allotment Options and
receipt by DTAG of the proceeds thereof and (ii) the expiration date of the
Over-Allotment Options (the earlier of (i) and (ii) being hereinafter referred
to as the "Determination Date"), by the amount by which such proceeds (less any
underwriters discount) exceeds $10,000,000 and, in the event the stated amount
of the Chrysler Series 1997-1 Support Letter of Credit exceeds such reduced
commitment, Dollar and Thrifty shall cause such letter of credit to be reduced
to the amount of such reduced commitment by causing a reduction in the Series
1997-1

Letter of Credit, or by providing the Series 1997-1 Letter of Credit Provider
with additional collateral or an Additional Series 1997-1 Support Letter of
Credit, all as provided in the Series 1997-1 Letter of Credit Agreement. Not
later than five Business Days after the Determination Date, DTAG shall deliver
to Chrysler a certificate executed by its chief financial officer certifying to
Chrysler the amount of any such over-allotment proceeds and related
underwriters' discount. The parties hereto confirm that on the Closing Date;
DTAG received $21,791,250 in net cash proceeds from the exercise of the
Over-Allotment Options and that a Chrysler Series 1997-1 Support Letter of
Credit in the amount of $38,208,750 was issued on the Closing Date.

     (b) If a successor Series 1997-1 Letter of Credit Provider is appointed,
promptly following the appointment of such successor Series 1997-1 Letter of
Credit Provider, and upon receipt of an Instruction to Transfer substantially in
the form of Annex G to the Chrysler Series 1997-1 Support Letter of Credit,
Chrysler shall deliver for the benefit of such successor and the current Series
1997-1 Letter of Credit Provider, in exchange for its outstanding Chrysler
Series 1997-1 Support Letter of Credit, a substitute letter of credit
substantially in the form of Exhibit A hereto having terms substantially
identical to its then outstanding Chrysler Series 1997-1 Support Letter of
Credit, but in favor of such successor.

     (c) (i) On September 30, 1999, and on each successive one year anniversary
thereof until the Chrysler Support Expiration Date (each, a "Reduction Date"),
the Chrysler Support Commitment shall be reduced by an amount equal to the
greater of (A) 20% of the Initial Chrysler Support Amount and (B) 50% of Excess
Cash Flow (as defined below) for the fiscal year of DTAG most recently ended
prior to the relevant Reduction Date (respectively, the "Support Reduction
Amount"). On or before the date that is 60 days prior to each Reduction Date,
DTAG shall deliver to Chrysler a certificate executed by its chief financial
officer certifying the Support Reduction Amount with respect to such Reduction
Date, which certificate shall include a reasonably detailed calculation of
Excess Cash Flow for the relevant fiscal year. "Excess Cash Flow" means for the
relevant period, an amount equal to the excess of (a) the sum, without
duplication, of (i) consolidated net income (loss) of DTAG and its subsidiaries
for such period, (ii) decreases in Working Capital for such period and (iii) an
amount equal to the amount of all non-cash charges deducted in arriving at such
consolidated net income (loss) (excluding book depreciation on revenue earning
vehicles and net losses on disposition of revenue earning vehicles) over (b) the
sum, without duplication, of (i) the amount of all non-cash credits included in
arriving at such consolidated net income (loss) (excluding net gains on
disposition of revenue earning vehicles), (ii) the aggregate amount of capital
expenditures for the period (other than those related to acquisitions of revenue
earning vehicles) of DTAG and its subsidiaries (excluding the principal amount
of indebtedness 


                                       6
<PAGE>   10

incurred in connection with such capital expenditures, whether incurred in such
period or in another period), (iii) the aggregate amount of all mandatory
prepayments required under any indebtedness to which DTAG or any of its
subsidiaries is a party, (iv) the aggregate amount of all scheduled principal
payments of indebtedness of DTAG or its subsidiaries, (including any term loans
and the principal component of payments in respect of capitalized lease
liabilities) made during such period and (v) increases in Working Capital for
such period. "Working Capital" means, with respect to the Parent, at any date,
the excess (or the deficit) of (a) the sum of the amounts that, in accordance
with GAAP, are set forth opposite the captions "accounts and notes receivable,
net" (excluding accounts receivable from Chrysler related to the MCAIC insurance
settlement and accounts receivables pledged to the Master Collateral Agent under
Sections 2.1(a)(iii) and 2.1(b)(iii) of the Master Collateral Agency Agreement),
"prepaid expenses and other assets", "income taxes receivable," and "deferred
income tax assets" or any like captions at such date over (b) the sum of the
amounts that, in accordance with GAAP, are set forth opposite the captions
"accounts payable (excluding outstanding checks included in accounts payable
related to vehicle financing ("float"))", "accrued liabilities", "income taxes
payable", "public liability and property damage" and "deferred income tax
liabilities", or any like captions, including any accruals for restructuring or
similar type reserves, at such date. The Company agrees that activities
affecting such account balances will be performed in the normal course in a
manner that is both usual and customary for management of such accounts and is
consistent with past practices. All accounting terms used in this definition
shall be interpreted, and all accounting determinations and computations set
forth in this definition shall be made, in accordance with, those generally
accepted accounting principles applied in the preparation of the audited
financial statements of DTAG and its subsidiaries as of December 31, 1996. At
Chrysler's request, DTAG shall cause its auditors to confirm the calculation of
Excess Cash Flow in a manner satisfactory to Chrysler.

          (ii) On or before the date that is 15 days prior to each Reduction
Date, pursuant to the terms of the Series 1997-1 Letter of Credit Agreement, the
Lessees shall deliver credit support to the Series 1997-1 Letter of Credit
Provider that will satisfy the requirements for a Series 1997-1 Credit Support
Arrangement under the Series 1997-1 Letter of Credit Agreement (such other
credit support, "Reduction Amount Credit Support"), in each case in an amount
equal to the Support Reduction Amount for the related Reduction Date. Upon
notification to Chrysler by the Series 1997-1 Letter of Credit Provider that it
has received the Reduction Amount Credit Support and that Chrysler's obligations
under the Series 1997-1 Chrysler Support Letter of Credit will be reduced by the
relevant Support Reduction Amount, the fees payable under Section 2.2 will be
adjusted accordingly.

Account relating to a Series 1997-1 LOC Credit Disbursement, a Series 1997-1 LOC

          against presentation of a draft or certificate which does not comply
          with the terms of a Chrysler Support Letter of Credit; or

               (g) any exchange, release or non-perfection of any collateral, or
          any release or amendment or waiver of or consent to departure from any
          guarantee, for all or any of the obligations of a Lessee or DTAG in
          respect of a Chrysler Support Letter of Credit.

          Section 2.7. Guaranty.

          (a) Guaranty. In order to induce Chrysler to execute and deliver this
Agreement and to issue the Chrysler Support Letters of Credit, and in
consideration thereof, each of DTAG, TRAC and Services (each, a "Guarantor"),
hereby (i) unconditionally and irrevocably, jointly and severally, guarantees to
Chrysler the obligations of the Lessees to make any payments required to be made
by them under this Agreement, (ii) agrees to cause the Lessees to duly and
punctually perform and observe all of the terms, conditions, covenants,
agreements and indemnities of the Lessees under this Agreement, and (iii) agrees
that, if for any reason whatsoever, any Lessee fails to so perform and observe
such terms, conditions, covenants, agreements and indemnities, the Guarantor
will duly and punctually perform and observe the same (the obligations referred
to in clauses (i) through (iii) above are collectively referred to as the
"Guaranteed Obligations"). The liabilities and obligations of the Guarantor
under the guaranty contained in this Section 2.7 (this "Guaranty") will be
absolute and unconditional under all circumstances. This Guaranty shall be a
guaranty of payment and not of collection, and the Guarantor hereby agrees that
it shall not be required that Chrysler, the Series 1997-1 Letter of Credit
Provider or the Trustee assert or enforce any rights against any Lessee or any
other person before or as a condition to the obligations of the Guarantor
pursuant to this Guaranty.

          (b) Scope of Guarantor's Liability. Each Guarantor's obligations
hereunder are independent of the obligations of the Lessees, any other guarantor
or any other Person, and Chrysler may enforce any of its rights hereunder
independently of any other right or

                                       12
<PAGE>   16

remedy that Chrysler may at any time hold with respect to this Agreement or any
security or other guaranty therefor. Without limiting the generality of the
foregoing, Chrysler may bring a separate action against each Guarantor without
first proceeding against any of the Lessees, any other guarantor or any other
Person, or any security held by Chrysler, and regardless of whether the Lessees
or any other guarantor or any other Person is joined in any such action. Each
Guarantor's liability hereunder shall at all times remain effective with respect
to the full amount due from the Lessees hereunder. Chrysler's rights hereunder
shall not be exhausted by any action taken by Chrysler until all Guaranteed
Obligations have been fully paid and performed.

         (c) Right to Amend this Agreement. Each Guarantor authorizes Chrysler
at any time and from time to time without notice and without affecting the
liability of such Guarantor hereunder, to: (a) alter the terms of all or any
part of the Guaranteed Obligations and any security and guaranties therefor
including without limitation modification of times for payment and rates of
interest; (b) accept new or additional instruments, documents, agreements,
security or guaranties in connection with all or any part of the Guaranteed
Obligations; (c) accept partial payments on the Guaranteed Obligations; (d)
waive, release, reconvey, terminate, abandon, subordinate, exchange, substitute,
transfer, compound, compromise, liquidate and enforce all or any part of the
Guaranteed Obligations and any security or guaranties therefor, and apply any
such security and direct the order or manner of sale thereof (and bid and
purchase at any such sale), subject to the terms of the Intercreditor Agreement
dated December 23, 1997, between, DTAG, Dollar, Thrifty, Chrysler and Credit
Suisse First Boston, as administrative agent and collateral agent; (e) release
any Lessee, any guarantor or any other Person from any personal liability with
respect to all or any part of the Guaranteed Obligations; and (f) assign its
rights under this Guaranty in whole or in part.

         (d) Waiver of Certain Rights by Guarantors. Each Guarantor hereby
waives each of the following to the fullest extent allowed by law:

                  (i)  any defense based upon:

                    (A)    the unenforceability or invalidity of any security or
                           other guaranty for the Guaranteed Obligations or the
                           lack of perfection or failure of priority of any
                           security for the Guaranteed Obligations; or

                    (B)    any act or omission of Chrysler or any other Person
                           that directly or indirectly results in the discharge
                           or release of any of the Lessees or any other Person
                           or any of the Guaranteed Obligations or any security
                           therefor; or

                                       13
<PAGE>   17

                    (C)    any disability or any other defense of any Lessee or
                           any other Person with respect to the Guaranteed
                           Obligations, whether consensual or arising by
                           operation of law or any bankruptcy, insolvency or
                           debtor-relief proceeding, or from any other cause;

                 (ii) any right (whether now or hereafter existing) to require
          Chrysler, as a condition to the enforcement of this Guaranty, to:

                    (A)    accelerate the Guaranteed Obligations;

                    (B)    give notice to each Guarantor of the terms, time and
                           place of any public or private sale of any security
                           for the Guaranteed Obligations; or

                    (C)    proceed against any Lessee, any other guarantor or
                           any other Person, or proceed against or exhaust any
                           security for the Guaranteed Obligations;

                 (iii) presentment, demand, protest and notice of any kind,
          including without limitation notices of default and notice of
          acceptance of this Guaranty;

                 (iv) all suretyship defenses and rights of every nature
          otherwise available under New York law and the laws of any other
          jurisdiction; and

                 (v) all other rights and defenses the assertion or exercise of
          which would in any way diminish the liability of each Guarantor
          hereunder.

          (e) Guarantors to Pay Chrysler's Expenses. Each Guarantor agrees to
pay to Chrysler, on demand, all costs and expenses, including reasonable
attorneys' and other professional and paraprofessional fees, incurred by
Chrysler in exercising any right, power or remedy conferred by this Guaranty, or
in the enforcement of this Guaranty, whether or not any action is filed in
connection therewith.

          (f) Reinstatement. This Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time payment of any of the amounts
payable by any Lessee under this Agreement is rescinded or must otherwise be
restored or returned by Chrysler, upon an event of bankruptcy, dissolution,
liquidation or reorganization of any Lessee or any Guarantor or upon or as a
result of the appointment of a receiver, intervenor or conservator of, or
trustee or similar officer for, any Lessee, any Guarantor, any other


                                       14
<PAGE>   18

guarantor or any other Person, or any substantial part of their respective
property, or otherwise, all as though such payment had not been made.


                                   ARTICLE III

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

          Section 3.1. Representations and Warranties of the Lessees and DTAG.
Each of the Lessees hereby represents and warrants (which representations and
warranties shall be deemed made on the Series 1997-1 Closing Date) to Chrysler,
as to itself, and DTAG represents and warrants (which representations and
warranties shall be deemed made on the Series 1997-1 Closing Date) to Chrysler,
as to itself and each of the Lessees, that:

          (a) Organization; Ownership; Power; Qualification. The Lessees and the
Guarantors are each (i) a corporation duly incorporated, validly existing and in
good standing under the laws of the jurisdiction of its incorporation and (ii)
has the corporate power and authority to own its properties and to carry on its
business as now being and hereafter proposed to be conducted.

          (b) Authorization; Enforceability. The Lessees and the Guarantors each
has the corporate power and has taken all necessary corporate action to
authorize it to execute, deliver and perform this Agreement and each of the
Chrysler Credit Support Security Documents in accordance with its terms, and to
consummate the transactions contemplated hereby. This Agreement and each of the
Chrysler Credit Support Security Documents has been duly executed and delivered
by each of such Lessees and the Guarantors and is a legal, valid and binding
obligation of each of such Lessees and the Guarantors, enforceable in accordance
with its terms, except as may be limited by bankruptcy, insolvency,
reorganization and similar laws affecting creditors generally and by the
availability of equitable remedies.

          (c) Compliance. (i) The execution, delivery and performance by each of
such Lessees and the Guarantors of this Agreement and each of the Chrysler
Credit Support Security Documents, and the consummation of the transactions
contemplated hereby, do not and will not (A) require any consent, approval,
authorization or registration not already obtained or effected, except where the
failure to obtain any such consent, approval or authorization or to register is
not reasonably likely to have a Material Adverse Effect, (B) violate any
applicable law with respect to each of such Lessees which violation is
reasonably likely to have a Material Adverse Effect, (C) conflict with, result
in a breach of, or constitute a default under the certificate of incorporation

<PAGE>   19

laws of any of the Lessees or the Guarantors, or under any indenture, agreement,
or other instrument to which any of such Lessees or the Guarantors is a party or
by which its properties may be bound, which conflict, breach or default is
reasonably likely to have a Material Adverse Effect, or (D) result in or require
the creation or imposition of any Lien upon or with respect to any property now
owned or hereafter acquired by any of such Lessees or the Guarantors except
Permitted Liens.

          (d) Revolving Credit Agreement. Each of the representations and
warranties under the Revolving Credit Agreement and the other Loan Documents are
true and correct.

          Section 3.2. Covenants of the Lessees and DTAG. So long as the
Chrysler Support Commitment is still in full force and effect or any amount is
owing to Chrysler hereunder, each of the Lessees and the Guarantors agrees that,
unless at any time Chrysler shall otherwise expressly consent in writing, it
will, and in the case of DTAG it will cause the Lessees to:

          (a) Preservation of Existence; Foreign Qualification. Do and cause to
be done at all times all things necessary to (i) maintain and preserve its
corporate existence and (ii) be duly qualified to do business and in good
standing as a foreign entity in each jurisdiction where the nature of its
business makes such qualification necessary and the failure to so qualify is
reasonably likely to have a Material Adverse Effect.

          (b) Accounting Methods; Financial Records. Maintain, and cause its
material Subsidiaries to maintain, a system of accounting established and
administered in accordance with GAAP, keep, and cause its material Subsidiaries
to keep, adequate records and books of account in which complete entries will be
made in accordance with such accounting principles and reflecting all
transactions required to be reflected by such accounting principles and keep,
and cause its material Subsidiaries to keep, accurate and complete records of
the Lessees's properties and assets.

be furnished to Chrysler financial statements, reports, notices and information
as set forth in Section 8.1.1 of the Revolving Credit Agreement.

          (d) Performance and Compliance with Covenants Incorporated by
Reference. Perform and comply with each of the covenants contained in the
Revolving Credit Agreement (or any other financing arrangement which may replace
the Revolving Credit Agreement) and the Master Leases (collectively, the "DTAG
Financing Agreements") as those covenants may be amended or modified from time
to time.


                                       16
<PAGE>   20

          (e) No Amendment. Obtain the consent or approval of Chrysler (which
shall not be unreasonably withheld) to (i) the terms of the initial CP Program
Documents and (ii) the amendment of any of the Related Documents or any of the
CP Program Documents which could be adverse to Chrysler.

          (f) Board Representation.

               (i) Subject to its fiduciary duties, DTAG's Board of Directors
          will nominate any person designated by Chrysler for election at each
          meeting (or in each action by written consent in lieu of a meeting) of
          stockholders of DTAG for the election of directors; provided that such
          person (A) is not a former officer or employee of DTAG but may be an
          officer or employee of Chrysler and its subsidiaries and (B) does not
          have a conflict of interest with DTAG; it being understood that DTAG
          agrees that Thomas Capo would be an acceptable Chrysler designee. The
          Governance Committee will fill any vacancy created on the Board of
          Directors as a result of the resignation or removal of a director
          designated by Chrysler with any person designated by Chrysler who
          satisfies the criteria set forth herein.

               (ii) DTAG will use its best efforts to cause the person nominated
          as provided in this Section 3.2(f) to be elected by the stockholders
          of DTAG and will solicit proxies in favor of such individual or any
          such successor and cause its Governance Committee to vote all proxies
          in which it has discretionary authority to exercise on behalf of such
          person at each meeting (or in each action by written consent in lieu
          of a meeting) of stockholders of DTAG.

               (iii) DTAG's obligations under this clause (f) shall terminate as
          provided in Section 4.8.

         (g) Downgrade of Letter of Credit Provider. In the event the credit
rating of the Series 1997-1 Letter of Credit Provider or a CP Program Letter of
Credit Provider falls below the minimum requirements of the MTN Program
Documents or CP Program Documents, respectively, or the letter of credit
provided by such Providers is set to expire prior to the termination of the MTN
Program or the CP Program, as the case may be, or, in the case of the Series
1997-1 Letter of Credit Provider, events have occurred which would permit its
replacement pursuant to Section 2.8 of the Series 1997-1 Letter of Credit
Agreement, Lessees shall use their best efforts to replace such letter of credit
providers or letters of credit with replacement providers or letters of credit
reasonably satisfactory to Chrysler.


                                       17
<PAGE>   21

         (h) Fiscal Year. DTAG will not change its fiscal year without the prior
written consent of Chrysler.

         (i) Credit Support Event of Default; Remedies Upon Occurrence of Credit
Support Event of Default.

               (i) A breach of any obligation hereunder, any Event of Default
          under the DTAG Financing Agreements or an Amortization Event shall
          constitute a Credit Support Event of Default.

               (ii) Upon the occurrence of a Credit Support Event of Default:

                    (A) an amount equal to any undrawn portion of any Chrysler
          Support Letter of Credit outstanding shall, at the election of
          Chrysler without demand upon or notice to DTAG or any Lessee, be
          deemed to have been paid or disbursed (notwithstanding that such
          amount may not in fact have been so paid or disbursed), and, upon
          notification by Chrysler to DTAG, DTAG and the Lessees shall be
          immediately obligated to reimburse Chrysler the amount deemed to have
          been so paid or disbursed by Chrysler as if a demand had been made by
          Chrysler to DTAG under Section 2.2 hereof; provided that so long as
          the Intercreditor Agreement is in effect, Chrysler can make such
          election only in the event of a failure by DTAG or any Lessee to (i)
          provide additional collateral or an Additional Series 1997-1 Support
          Letter of Credit when required by Section 2.1(a), (ii) provide
          Reduction Amount Credit Support when required by Section 2.1(c), (iii)
          pay within three Business Days of the due date therefor any Fees
          required by Section 2.2 and (iv) make a reimbursement payment when
          required by Section 2.3. Any amounts so received by Chrysler from DTAG
          or the Lessees pursuant to this Section shall be held as collateral
          security for the repayment of DTAG's or the Lessees' obligations in
          connection with the Chrysler Support Letters of Credit (provided, that
          with respect to any Support Credit Disbursement that is with respect
          to a Series 1997-1 LOC Credit Disbursement for amounts owed by DTAG
          under Section 4.19 of the Series 1997-1 Supplement, such obligation is
          solely the obligation of DTAG). At any time when all Chrysler Support
          Letters of Credit shall terminate and all its obligations thereunder
          are either terminated or paid or reimbursed in full (subject, however,
          to reinstatement in the event any payment in respect of such Letters
          of Credit is recovered in any manner from Chrysler), Chrysler will
          return to DTAG or the Lessees the aggregate amount deposited with
          Chrysler and not theretofore applied by Chrysler to any reimbursement
          obligation hereunder. At such time when all Credit Support Events of
          Default shall have been cured or waived, Chrysler shall


                                       18
<PAGE>   22

          return to DTAG and the Lessees all amounts then on deposit with
          Chrysler pursuant to this Section. Earnings on all amounts on deposit
          pursuant to this Section shall, until their application to any
          reimbursement obligation or their return to DTAG or the Lessees, as
          the case may be, shall be held by Chrysler as additional collateral
          security for the repayment of DTAG's or each Lessee's obligations in
          connection with the Letters of Credit issued by Chrysler;

                    (B) the Chrysler Support Commitment shall terminate;

                    (C) subject to the terms of the Intercreditor Agreement,
          Chrysler shall be entitled to exercise all of its remedies under the
          Credit Support Security Documents together with any and all other
          remedies available to it under law; and

                    (D) Chrysler may seek specific performance of any of the
          non-monetary obligations of DTAG or any Lessee hereunder.

          Section 3.3. Injunctive Relief with Respect to Certain Covenants. DTAG
acknowledges and agrees that the covenants and obligations of DTAG under Section
3.2(f) relate to special, unique and extraordinary matters and that a violation
of any of the terms of such covenants and obligations will cause Chrysler
irreparable injury for which adequate remedies are not available at law.
Therefore, DTAG agrees that Chrysler shall be entitled to an injunction,
restraining order or such other equitable relief (without the requirement to
post bond) restraining DTAG from committing any violation of the coven ants and
obligations contained in Section 3.2(f). These injunctive remedies are
cumulative and are in addition to any other rights and remedies Chrysler may
have at law or in equity.

          Section 3.4. Chrysler Covenants. Chrysler covenants and agrees with
the Lessees and DTAG that, on the Series 1997-1 Closing Date, it will provide to
the Trustee, DTAG, each of the Lessees, and the Series 1997-1 Letter of Credit
Provider, the favorable written opinion of counsel to Chrysler, addressing the
due authorization, execution and delivery of the Chrysler Series 1997-1 Support
Letter of Credit and the enforceability thereof against Chrysler.

any of the Lessees shall be asserted by Chrysler as a defense to payment under a

included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose.

          Section 4.15. Application of Funds. Upon receipt of the deposited

the Series 1997-1 Supplement, Chrysler shall apply such amounts to the payment

payment in full, in cash, of the obligations hereunder of DTAG and each of the

required to be deposited in the Series 1998-1 Distribution Account on such
Payment Date, such Principal Collections may, at the written direction of the
Master Servicer, be applied to cover principal payments due to or for the
benefit of Noteholders of other Group II Series of Notes.  Any such
reallocation will not result in a reduction of the Aggregate Principal Balance
or in the Invested Amount of the Series 1998-1 Notes.

                 (e)  Unallocated Principal Collections.  If, after giving
effect to Section 4.2(d), Principal Collections allocated to the Series 1998-1
Notes on any Payment Date are in excess of the amount required to pay amounts
due in respect of the Series 1998-1 Notes on such Payment Date in full, then
any such excess Principal Collections shall be allocated to the Retained
Distribution Account (provided that no Series 1998-1 Enhancement Deficiency or
Asset Amount Deficiency exists or would result from such allocation).

                 In addition, for purposes of Section 4.2(a) of the Base
Indenture, the Master Servicer in its capacity as such under the Master Lease
shall cause all Collections allocable to Group II Collateral in accordance with
the Indenture and the Master Collateral Agency Agreement, as applicable, to be
paid directly into the Group II Collection Account or the Master Collateral
Account, as applicable.

                 administrative sub-account for the Series 1998-1 Noteholders
                 (such sub-account, the "Series 1998-1 Accrued Interest
                 Account").

                                  (c)  All Collections in respect of the Group
                 II Collateral and allocable to the Group II Series of Notes

         the Group II Collection Account (each such date, a "Series 1998-1
         Deposit Date"), the Master Servicer will direct the Trustee in writing

                                  amount determined as set forth in Section
                                  4.7(a)(v)(2) above for such day, which amount

                          (d)  Additional Allocations.  Notwithstanding the
         foregoing provisions of this Section 4.7,

                          (i)  provided the Series 1998-1 Rapid Amortization
                 Period has not commenced, amounts allocated to the Series
                 1998-1 Excess Funding Account that are not required to make
                 payments under the Series 1998-1 Notes pursuant hereto may, as
                 and to the extent permitted in the related Supplements, be
                 used to pay the principal amount of other Group II Series of
                 Notes that are then in amortization and, after such payment,
                 any remaining funds may, at RCFC's option, be (i) used to
                 finance or acquire Vehicles, to the extent Eligible Vehicles
                 have been requested by any of the Lessees under the Master
                 Lease or (ii) transferred, on any Payment Date, to the
                 Retained Distribution Account, to the extent that the Retained
                 Amount equals or exceeds zero after giving effect to such
                 payment and so long as no Series 1998-1 Enhancement Deficiency
                 or Asset Amount Deficiency exists or would result therefrom;
                 provided, however, that funds remaining after the application
                 of such funds to the payment of the principal amount of other
                 Group II Series of Notes that are in amortization and to the
                 financing or acquisition of Group II Vehicles may be
                 transferred to the Retained Distribution Account on a day
                 other than a Payment Date if the Master Servicer furnishes to
                 the Trustee an Officer's Certificate to the effect that such
                 transfer will not cause any of the foregoing deficiencies to
                 occur either on the date that such transfer is made or, in the
                 reasonable anticipation of the Master Servicer, on the next
                 Payment Date.  Funds in the Retained Distribution Account
                 shall, at the option of RCFC, be available to finance or
                 acquire Vehicles, to the extent Eligible Vehicles have been
                 requested by any of the Lessees under the Master Lease, or for
                 distribution to the Retained Interestholder (including any
                 advances made under the Demand Note);

                          (ii)  in the event that the Master Servicer is not
                 DTAG or an Affiliate of DTAG, the Master Servicer shall not be
                 entitled to withhold any amounts pursuant to Section 4.2(c)
                 and the Trustee shall deposit amounts payable to DTAG in its
                 capacity as the Master Servicer in the Collection Account
                 pursuant to the provisions of Section 4.2 on each Series
                 1998-1 Deposit Date;

                          (iii)  any amounts withheld by the Master Servicer
                 and not deposited in the Collection Account pursuant to
                 Section 4.2(c) shall be deemed to be deposited in the
                 Collection Account on the date such amounts are withheld for
                 purposes of determining the amounts to be allocated pursuant
                 to this Section 4.7;

                          (iv)  if there is more than one Series of Group II
                 Series of Notes outstanding, then Sections 4.7(a)(i)(5),
                 4.7(b)(i)(3) and 4.7(c)(i)(3) above shall not

                 be duplicative with any similar provisions contained in any
                 other Supplement and the Retained Interestholder shall only be
                 paid such amount once with respect to any Payment Date; and

                          (v)  RCFC may, from time to time in its sole
                 discretion, increase the Series 1998-1 Available Subordinated
                 Amount by (a) (i) allocating to the Series 1998-1 Available
                 Subordinated Amount Eligible Vehicles theretofore allocated to
                 the Retained Interest and (ii) delivering to the Trustee an
                 Officer's Certificate affirming with respect to such Vehicles
                 the representations and warranties set forth in Section 6.14
                 of the Base Indenture (and an Opinion of Counsel to the same
                 effect) or (b) (i) depositing funds into the Series 1998-1
                 Excess Funding Account by transfer from the Retained
                 Distribution Account or otherwise, and (ii) delivering to the
                 Master Servicer and the Trustee an Officer's Certificate
                 setting forth the amount of such funds and stating that such
                 funds shall be allocated to the Series 1998-1 Available
                 Subordinated Amount; provided, however, that (x) RCFC shall
                 have no obligation to so increase the Series 1998-1 Available
                 Subordinated Amount at any time and (y) RCFC may not increase
                 the Series 1998-1 Available Subordinated Amount at any time if
                 the amount of such increase, together with the sum of the
                 amounts of all prior increases, if any, of the Series 1998-1
                 Available Subordinated Amount would exceed the applicable
                 Series 1998-1 Available Subordinated Amount Maximum Increase,
                 excluding from such calculation any increase in the Series
                 1998-1 Available Subordinated Amount (1) through Recoveries or
                 from funds constituting repayments of principal under the
                 Demand Note, or (2) relating to an increase in the Minimum
                 Series 1998-1  Enhancement Amount that results from (a) an
                 increase in the ratio of Group II Vehicles that are
                 Non-Program Vehicles to all Group II Vehicles, (b) a reduction
                 in the aggregate amount of cash and Permitted Investments in
                 the Collection Account and the Master Collateral Account that
                 are allocable to the Group II Series of Notes, or (c) a
                 decrease in Market Value Adjustment Percentage;

                          (vi)  If, on any Payment Date during the Series
                 1998-1 Revolving Period, a Mandatory Decrease shall be
                 required under Section 4A.3(a) of this Supplement and the
                 amounts allocated to the Series 1998-1 Invested Amount under
                 Section 4.7(a)(i)(2) are less than the amount of such required
                 Decrease, then, in such event, any funds (i) on deposit in the
                 Collection Account which are allocable to the Retained Amount
                 or (ii) on deposit in the excess funding accounts for other
                 Group II Series of Notes issued and outstanding under the
                 Indenture which amounts are in excess of the amounts necessary
                 to be on deposit in each such excess funding account in order
                 that (x) no Asset Amount Deficiency occur, (y) no shortfall in
                 the required level of enhancement for each such Group II
                 Series of Notes shall occur, including any portion of such
                 enhancement that is required to be in liquid funds, and (z) no
                 Amortization Event for any such series or event that with the
                 giving of notice or passage of time would become an
                 Amortization Event

                 for any such Group II Series of Notes (such amounts as are set
                 forth in clauses (i) and (ii) of this subparagraph (vi) being
                 referred to herein as "Excess Amounts") shall, in each such
                 case, be deposited into the Series 1998-1 Distribution Account
                 as Principal Collections in an aggregate amount up to the
                 amount of any such deficiency and shall be used, in accordance
                 with Section 4.10(b), to reduce the Series 1998-1 Invested
                 Amount;

                          (vii)  If, on any Payment Date during the Series
                 1998-1 Controlled Amortization Period, the Monthly Total
                 Principal Allocation under Section 4.7(b)(i)(2) is less than
                 the Controlled Distribution Amount for the Related Month and
                 required to be paid on such Payment Date, then, in either such
                 event, any funds constituting Excess Amounts shall, in each
                 such case, be deposited into the Series 1998-1 Distribution
                 Account as Principal Collections in an aggregate amount up to
                 the amount of any such deficiency and shall be used, in
                 accordance with Section 4.10(a) to reduce the Series 1998-1
                 Invested Amount; and

                          (viii)  If, on any Payment Date during the Series
                 1998-1 Rapid Amortization Period, the Monthly Total Principal
                 Allocation under Section 4.7(c)(i)(3) is insufficient to
                 reduce the Series 1998-1 Invested Amount to zero, then, in
                 such event, any funds constituting Excess Amounts shall, in
                 each such case, be deposited into the Series 1998-1
                 Distribution Account as Principal Collections in an aggregate
                 amount up to the amount of any such deficiency and shall be
                 used, in accordance with Section 4.10(a) or (b), as
                 applicable, to reduce the Series 1998-1 Invested Amount.

                          Section 4.8  Monthly Payments.

                          All of the payments in this Section 4.8 will be made
         in accordance with written direction of the Master Servicer.  On each
         Reporting Date, as provided below, the Master Servicer shall instruct
         the Trustee to withdraw, and on the following Payment Date the
         Trustee, acting in accordance with such instructions, shall withdraw
         the amounts required to be withdrawn from the Group II Collection
         Account pursuant to Sections 4.8(a) through (c) below in respect of
         all funds available from Series 1998-1 Interest Collections processed
         since the preceding Payment Date and allocated to the holders of the
         Series 1998-1 Notes.

                          (a)  Note Interest with respect to the Series 1998-1
         Notes.  On each Reporting Date, the Master Servicer shall instruct the
         Trustee or the Paying Agent to withdraw on the next succeeding Payment
         Date from the Series 1998-1 Accrued Interest Account and deposit in
         the Series 1998-1 Distribution Account the amount on deposit therein
         available for the payment of the Series 1998-1 Interest Amount. On
         such Determination Date, the Master Servicer shall further instruct
         the Trustee in writing to withdraw on the next succeeding Payment Date
         from the Series 1998-1 Excess Funding Account the lesser of (i) the
         amount on deposit in the Series 1998-1 Excess Funding

         Account and (ii) the excess, if any, of the Series 1998-1 Interest
         Amount over the amount withdrawn from the Series 1998-1 Accrued
         Interest Account pursuant to the preceding sentence and deposit such
         amount to the Series 1998-1 Distribution Account.  If the amounts
         described in this Section 4.8(a) are insufficient, after taking into
         account any funds available in the Series 1998-1 Excess Funding
         Account and any portion of the Series 1998-1 Letter of Credit Amount
         applied as described in Section 4.9 of this Supplement, to pay the
         Series 1998-1 Interest Amount on any Payment Date, payments of
         interest to the Series 1998-1 Noteholders will be reduced by the
         amount of such shortfall.  The amount, if any, of such shortfall on
         any Payment Date shall be referred to as the "Series 1998-1 Deficiency
         Amount".  Interest shall accrue on the Series 1998-1 Deficiency Amount
         at the applicable Series 1998-1 Note Rate.  On the following Payment
         Date, the Trustee shall withdraw the Series 1998-1 Interest Amount
         from the Series 1998-1 Accrued Interest Account and, to the extent
         provided in Section 4.9 of this Supplement, amounts withdrawn from the
         Series 1998-1 Excess Funding Account and any applied portion of the
         Series 1998-1 Letter of Credit Amount, and shall deposit such amount
         in the Series 1998-1 Distribution Account; provided that the amounts

         Trustee in writing to instruct the Paying Agent to transfer to the
         Retained Distribution Account (established pursuant to Section 4.1(b)
         of the Base Indenture) (i) all funds which are in the Collection
         Account that have been allocated to the Retained Distribution Account
         as of such Payment Date and (ii) all funds that were previously
         allocated to the Retained Distribution Account but not transferred to
         the Retained Distribution Account.

                          Section 4.12 Series 1998-1 Distribution Account.

                          (a)  Establishment of Series 1998-1 Distribution
         Account.  The Trustee shall establish and maintain in the name of the
         Trustee for the benefit of the Series 1998-1 Noteholders, or cause to
         be established and maintained, an account (the "Series 1998-1
         Distribution Account"), bearing a designation clearly indicating that
         the funds deposited therein are held for the benefit of the Series
         1998-1 Noteholders.  The Series 1998-1 Distribution Account shall be
         maintained (i) with a Qualified Institution, or (ii) as a segregated
         trust account with the corporate trust department of a depository
         institution or trust company having corporate trust powers and acting
         as trustee for funds deposited in the Series 1998-1 Distribution
         Account.  If the Series 1998-1 Distribution Account is not maintained
         in accordance with the previous sentence, the Master Servicer shall
         establish a new Series 1998-1 Distribution Account, within ten (10)
         Business Days after obtaining knowledge of such fact, which complies
         with such sentence, and shall instruct the Trustee to transfer all
         cash and investments from the non-qualifying Series 1998-1
         Distribution Account into the new Series 1998-1 Distribution Account.
         Initially, the Series 1998-1 Distribution Account will be established
         with the Trustee.

                          (b)  Administration of the Series 1998-1 Distribution
         Account.  The Master Servicer shall instruct the institution
         maintaining the Series 1998-1 Distribution Account in writing to
         invest funds on deposit in the Series 1998-1 Distribution Account at
         all times in Permitted Investments; provided, however, that any such
         investment shall mature not later than the Business Day prior to the
         Payment Date following the date on which such funds were received,
         unless any Permitted Investment held in the Series 1998-1 Distribution
         Account is held with the Trustee, in which case such investment may
         mature on such Payment Date provided that such funds shall be
         available for withdrawal on or prior to such Payment Date.  The
         Trustee shall hold, for the benefit of the Series 1998-1 Noteholders,
         possession of any negotiable instruments or securities evidencing the
         Permitted Investments from the time of purchase thereof until the time
         of maturity.

         Servicer shall have the authority to instruct the Trustee in writing
         with respect to the investment of funds on deposit in the Series
         1998-1 Distribution Account.  All interest and earnings (net of losses
         and investment expenses) on funds on deposit in the Series 1998-1
         Distribution Account shall be deemed to be on deposit and available
         for distribution.

                          (d)  Series 1998-1 Distribution Account Constitutes
         Additional Collateral for Series 1998-1 Notes.  In order to secure and
         provide for the payment of the RCFC Obligations with respect to the
         Series 1998-1 Notes (but not the other Notes), RCFC hereby assigns,
         pledges, grants, transfers and sets over to the Trustee, for the
         benefit of the Series 1998-1 Noteholders, all of RCFC's right, title
         and interest in and to the following (whether now or hereafter

         are referred to, collectively, as the "Series 1998-1 Distribution
         Account Collateral").  The Trustee shall possess all right, title and
         interest in all funds on deposit from time to time in the Series
         1998-1 Distribution Account and in all proceeds thereof.  The Series
         1998-1 Distribution Account Collateral shall be under the sole
         dominion and control of the Trustee, in each case for the benefit of
         the Series 1998-1 Noteholders.

                          Section 4.13 The Servicer's Failure to Instruct the
         Trustee to Make a Deposit or Payment.  If the Master Servicer fails to
         give notice or instructions to make any payment from or deposit into
         the Collection Account required to be given by the Master Servicer, at
         the time specified in the Master Lease or any other Related Document
         (including applicable grace periods), and such failure is known by the
         Trustee, the Trustee shall make such payment or deposit into or from
         the Collection Account without such notice or instruction from the
         Master Servicer if and to the extent that the Trustee has been
         furnished information adequate, in the sole discretion of the Trustee,
         to determine the amounts and beneficiaries of such payments.  Pursuant
         to the Master Lease, the Master Servicer has agreed that it shall,
         upon request of the Trustee, promptly provide the Trustee with all
         information necessary to allow the Trustee to make such a payment or
         deposit.

         each Payment Date, the Master Servicer shall notify the Trustee and

                 Section 4.17  Conversion.  If on any Business Day there exists
Series 1998-1 Lease Payment Losses, including after an LOC Termination
Disbursement (as defined in the Liquidity Agreement) has been made as provided

the Liquidity Agreement) shall be reduced, and (B) the amount of LOC Credit
Disbursements (as defined in the Liquidity Agreement) Outstanding shall be
increased, in each case, by an amount equal to the lesser of (a) the amount by

of Credit Amount (which Series 1998-1 Letter of Credit Amount shall, in any
event, be drawn, in accordance with the second paragraph of Section 4.14 as a
Credit Draw) and (b) the aggregate amount of LOC Liquidity Disbursements (such
reduction and increase shall be referred to as a "Conversion").  On the

receiving written notice of such Series 1998-1 Lease Payment Losses from the
Master Servicer) shall direct the Trustee to deliver to the Series 1998-1
Letter of Credit Provider a Notice of Conversion in the form of Exhibit B to
the CP Enhancement Letter of Credit Application and Agreement by 1:00 p.m. (New
York City time) on such Business Day.

                          Section 4.18 The Series 1998-1 Cash Collateral
Account.

                          (a)  Upon receipt of written notice of a draw on the
         Series 1998-1 Letter of Credit from the Enhancement Agent pursuant to
         Section 4.14, the Trustee shall establish and maintain in the name of
         the Trustee for the benefit of the Series 1998-1 Noteholders, or cause
         to be established and maintained, the Series 1998-1 Cash Collateral
         Account bearing a designation clearly indicating that the funds
         deposited therein are held for the Series 1998-1 Noteholders.  The
         Series 1998-1 Cash Collateral Account shall be maintained (i) with a
         Qualified Institution, or (ii) as a segregated trust account with the
         corporate trust department of a depository institution or trust
         company having corporate trust powers and acting as trustee for funds
         deposited in the Series 1998-1 Cash Collateral Account.  If the Series
         1998-1 Cash Collateral Account is not maintained in accordance with
         the prior sentence, then within 10 Business Days after obtaining
         knowledge of such fact, the Master Servicer has agreed pursuant to the
         Master Lease that it shall establish a new Series 1998-1 Cash
         Collateral Account which complies with such sentence and shall
         instruct the Trustee in writing to transfer into the new Series 1998-1
         Cash Collateral Account all cash and investments from the
         non-qualifying Series 1998-1 Cash Collateral Account.  When
         established, the Series 1998-1 Cash Collateral Account is intended to
         function in all respects as the replacement for, and the equivalent
         of, the Series 1998-1 Letter of Credit.  Accordingly, following its
         creation, each reference to a draw on the Series 1998-1 Letter of
         Credit shall refer to withdrawals from the Series 1998-1 Cash
         Collateral Account and references to similar terms shall mean and be a
         reference to actions taken with respect to the Series 1998-1 Cash
         Collateral Account that correspond to actions that otherwise would
         have been taken with respect to the Series 1998-1 Letter of Credit.
         Without limiting the generality of the foregoing, upon funding of the
         Series 1998-1 Cash Collateral Account, the Trustee shall, at all times
         when the Enhancement Agent is otherwise required to make a draw under
         the Series 1998-1 Letter of Credit pursuant to Section 4.14 or 4.16 of
         this Supplement, make a draw from the Series 1998-1 Cash Collateral
         Account in the amount and at such time as a draw would be made under





                                      -65-
<PAGE>   70
         the Series 1998-1 Letter of Credit pursuant to Section 4.14 or 4.16 of
         this Supplement.  The Trustee shall provide written notice to DTAG of
         any draw from the Series 1998-1 Cash Collateral Account pursuant to
         Section 4.14 or 4.16 of this Supplement.

                          (b)  In order to secure and provide for the repayment
         and payment of the obligations of RCFC with respect to the Series
         1998-1 Notes (but not any other Series of Notes), RCFC hereby assigns,
         pledges, grants, transfers and sets over to the Trustee, for the
         benefit of the Series 1998-1 Noteholders, all of RCFC's right, title
         and interest in and to the following (whether now or hereafter
         existing and whether now owned or hereafter acquired):  (i) the Series
         1998-1 Cash Collateral Account; (ii) all funds on deposit therein from
         time to time; (iii) all certificates and instruments, if any,
         representing or evidencing any or all of the Series 1998-1 Cash
         Collateral Account or the funds on deposit therein from time to time;
         (iv) all Permitted Investments made at any time and from time to time
         with the monies in the Series 1998-1 Cash Collateral Account; and (v)
         all proceeds of any and all of the foregoing, including, without
         limitation, cash.  The Trustee shall possess all right, title and
         interest in all funds on deposit from time to time in the Series
         1998-1 Cash Collateral Account and in all proceeds thereof.  The
         Series 1998-1 Cash Collateral Account shall be under the sole dominion
         and control of the Trustee for the benefit of the Series 1998-1
         Noteholders and the Series 1998-1 Letter of Credit Provider, as their
         interests appear herein, which interest in the case of the Series
         1998-1 Letter of Credit Provider shall be subject to the interests of
         the holders of Series 1998-1 Notes as provided herein.

                          (c)  Funds on deposit in the Series 1998-1 Cash
         Collateral Account shall, at the written direction of the Master
         Servicer given pursuant to the Master Lease, be invested by the
         Trustee in Permitted Investments subject to the right of the Liquidity
         Agent pursuant to Section 5.04 of the Collateral Agreement to direct
         the investment of such amounts so long as a Liquidity Agreement
         Amortization Event (other than Scheduled Liquidity Agreement
         Amortization Events) shall have occurred and be continuing.  Funds on
         deposit in the Series 1998-1 Cash Collateral Account on any Payment
         Date, after giving effect to any deposits to or withdrawals from the
         Series 1998-1 Cash Collateral Account on such Payment Date, shall be
         invested in Permitted Investments that will mature at such time that
         such funds will be available for withdrawal on or prior to the
         following Payment Date.  The proceeds of any such investment, to the
         extent not distributed on such Payment Date, shall be invested in
         Permitted Investments that will mature at such time that such funds
         will be available for withdrawal on or prior to the Payment Date
         immediately following the date of such investment.  The Trustee shall
         maintain for the benefit of the Series 1998-1 Noteholders and the
         Series 1998-1 Letter of Credit Provider as their interests appear
         herein, which interest in the case of the Series 1998-1 Letter of
         Credit Provider shall be subject to the interests of the holders of
         the Series 1998-1 Notes as provided herein, possession of the
         negotiable instruments or securities evidencing the Permitted
         Investments from the time of purchase thereof until the time of sale
         or maturity.  On each Payment Date, all interest and earnings (net of
         losses and investment expenses) accrued since the preceding Payment
         Date on funds on





                                      -66-
<PAGE>   71
         deposit in the Series 1998-1 Cash Collateral Account shall be paid to
         the Series 1998-1 Letter of Credit Provider to the extent of any
         unreimbursed draws on the Series 1998-1 Letter of Credit.  Subject to
         the restrictions set forth above, the Master Servicer, or a Person
         designated in writing by the Master Servicer with written notification
         thereof to the Trustee, shall have the authority to instruct the
         Trustee in writing with respect to the investment of funds on deposit
         in the Series 1998-1 Cash Collateral Account.  For purposes of
         determining the availability of funds or the balances in the Series
         1998-1 Cash Collateral Account for any reason under the Indenture, all
         investment earnings on such funds shall be deemed not to be available
         or on deposit.

                          (d)  Series 1998-1 Cash Collateral Account Surplus.
         In the event that the Series 1998-1 Cash Collateral Account Surplus on
         any Payment Date, after giving effect to all withdrawals from the
         Series 1998-1 Cash Collateral Account, is greater than zero, the
         Trustee, acting in accordance with the written instructions of the
         Servicer, shall withdraw from the Series 1998-1 Cash Collateral
         Account an amount equal to the Series 1998-1 Cash Collateral Amount
         Surplus and shall pay from such amount to the Series 1998-1 Letter of
         Credit Provider, an amount equal to the amount of unreimbursed draws
         under the Series 1998-1 Letter of Credit.

                          (e)  Termination of Series 1998-1 Cash Collateral
         Account.  Upon the later to occur of (i) the termination of the
         Indenture pursuant to Section 10.1 of the Base Indenture and (ii) the
         Business Day immediately following the Series 1998-1 Letter of Credit
         Expiration Date, the Trustee, acting in accordance with the written
         instructions of the Servicer,  after the prior payment of all amounts
         owing to the Series 1998-1 Noteholders and payable from the Series
         1998-1 Cash Collateral Account as provided herein, shall withdraw from
         the Series 1998-1 Cash Collateral Account all amounts on deposit
         therein for payment to the Series 1998-1 Letter of Credit Provider to
         the extent of unreimbursed draws on the Series 1998-1 Letter of
         Credit.

         Section 4.19.  Appointment of Enhancement Agent. Bankers Trust Company
is hereby appointed to act as Enhancement Agent in respect of the Series 1998-1

                 FOR VALUE RECEIVED, the undersigned, DOLLAR THRIFTY AUTOMOTIVE
GROUP, INC., a Delaware corporation ("DTAG"), promises to pay to RENTAL CAR
FINANCE CORP., an Oklahoma corporation ("RCFC"), on demand (the "Demand Date"),
(a) the principal sum of [                ] or (b) such other amount, shown on
Schedule A attached hereto (and any continuation thereof) made by RCFC, as the
aggregate unpaid principal balance hereof, including the aggregate unpaid
principal amount of Demand Note Advances (as defined herein) made from funds on
deposit in the Series 1998-1 Collection Account from time to time.

         1.      Principal Payment Date.  Any unpaid principal of this
promissory note (this "Demand Note") shall be paid on the Demand Date.

         2.      Interest.  DTAG also promises to pay interest on the unpaid
principal amount hereof from time to time outstanding at an interest rate of
one-year LIBOR, as determined for such period in the manner set forth under the
Base Indenture, dated as of December 13, 1995 between RCFC and Bankers Trust,
as Trustee (the "Base Indenture") as supplemented by the Series 1998-1
Supplement (the "Series 1998-1 Supplement" and together with the Base
Indenture, the "Indenture") for the determination of LIBOR thereunder, plus
1.5% (the "Demand Note Rate")from the date hereof until the principal amount
shall be paid in full.  Capitalized terms used herein and not otherwise defined
herein shall have the meanings set forth therefor in the Indenture.

         3.      Prepayments.  The DTAG shall repay in full the unpaid
principal amount of the Demand Note upon the Demand Date hereof.  Prior
thereto, the DTAG:

         (a)     may, from time to time on any Business Day, make a voluntary
prepayment, in whole or in part, of the outstanding principal amount of this
Demand Note; provided, however, that

           (i)   any such prepayment shall be made after all payments due on
         such Business Day under the Related Documents have been paid in full;

           (ii)  no Event of Default or Lease Event of Default shall have
         occurred and be continuing; and
<PAGE>   81
           (iii) such voluntary prepayments shall require at least three but no
         more than five Business Days' prior written notice to RCFC.

Each prepayment of any Demand Note made pursuant to this Section 3 shall be
without premium or penalty.

         4.      Demand Note Advances.  RCFC agrees to make advances ("Demand
Note Advances") upon request from DTAG as borrower out of and not to exceed in
any Related Month the amount by which Recoveries constituting Profits that may
be lent under this Demand Note pursuant to Sections 4.7(a)(ii)(1),
4.7(b)(ii)(1), and 4.7(c)(ii)(1) of the Series 1998-1 Supplement.  Such Demand
Note Advances are repayable by DTAG, with interest, on each Demand Date upon
demand by RCFC or the Trustee, as assignee of RCFC.  Demand Note Advances shall
accrue interest on the outstanding balance thereof at the Demand Note Rate then
applicable. The date, amount, interest rate and duration of the Interest Period
(if applicable) of each Demand Note Advance made by RCFC to DTAG and each
payment made on account of the principal thereof, shall be recorded by RCFC on
its books and, prior to any transfer of this Demand Note, endorsed by RCFC on
Schedule A attached hereto or any continuation thereof, provided that the
failure of RCFC to make any such recordation or endorsement shall not affect
the obligations of DTAG to make a payment when due of any amount owing
hereunder or under any other Related Document in respect of the Demand Note
Advances made by RCFC.

         5.      Subordination.

         (a)     RCFC, as subordinated lender under this Demand Note in respect
of Demand Note Advances (the "Subordinated  Lender") hereby agrees that the
Subordinated Lender's right under this Demand Note is expressly subordinated to
all payment obligations due to the Trustee, as assignee of the Master Lease,
(the "Senior Lender") under the Master Lease (the "Payment Obligations").  The
Subordinated Lender hereby agrees that the payment of this Demand Note is
hereby expressly subordinated, in accordance with the terms hereof, to the
prior payment in full of the Payment Obligations in cash.

         (b)     Upon the maturity of any Payment Obligation (including
interest thereon or fees or any other amounts owing in respect thereof),
whether on the Payment Date (after any extension thereof), by acceleration or
otherwise, all payments thereof and premium, if any, and interest thereon or
fees or any other amounts owing in respect thereof, in each case to the extent
due and owing, shall first be paid in full in cash, or such payment duly
provided for in cash or in a manner satisfactory to the Senior Lender, before
any payment is made on account of the Demand Note.  The Subordinated Lender
hereby agrees that, so long as an Event of Default or a Lease Event of Default,
or event which with notice or lapse of time or both would constitute an Event
of Default or a Lease Event of Default, in respect of any Payment Obligations,
it will not ask, demand, sue for, or otherwise take, accept or receive, any
amounts in respect of this Demand Note.

<PAGE>   82
         (c)     In the event that notwithstanding the provisions of the
preceding Section 5(b), DTAG shall make any payment on account of this Demand
Note at a time when payment is not permitted by said Section 5(b), such payment
shall be held by the Subordinated Lender or its representative, in trust for
the benefit of, and shall be paid forthwith over and delivered to, the Senior
Lender or its representative for application to the payment of all Payment
Obligations remaining unpaid to the extent necessary to pay all Payment
Obligations in full in cash in accordance with the terms of the Master Lease,
after giving effect to any concurrent payment or distribution to or for the
Payment Obligations.  Without in any way modifying the provisions hereof or
affecting the subordination effected hereby if such notice is not given, DTAG
shall give the Subordinated Lender prompt written notice of any payment made on
the Demand Note and any Demand Date of Payment Obligations after which such
Payment Obligations remain unsatisfied.

         (d)      Upon any distribution of assets of DTAG upon any dissolution,
winding up, liquidation or reorganization of DTAG (whether in bankruptcy,
insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or otherwise):

            (i)   the Senior Lender shall first be entitled to receive payment
         in full of the Payment Obligations in cash or in a manner satisfactory
         to the Senior Lender (including, without limitation, all interest
         accruing after the commencement of any bankruptcy, insolvency,
         receivership or similar proceeding at the rate provided in the
         governing documentation whether or not such interest is an allowed
         claim in such proceeding) before the Subordinated Lender is entitled
         to receive any payment out of the proceeds from or distributions made
         under the Master Lease;

            (ii)  any payment out of the proceeds from or distributions made
         under the Master Lease of any kind or character, whether in cash,
         property or securities to which the Subordinated Lender would be
         entitled except for the provisions hereof, shall be paid by the
         liquidating trustee or agent or other person making such payment or
         distribution, whether a trustee or agent, directly to the Senior
         Lender or its representative under the agreements pursuant to which
         the Payment Obligations may have been made, to the extent necessary to
         make payment in full of all Payment Obligations remaining unpaid,
         after giving effect to any concurrent payment or distribution to the
         Senior Lender in respect of the Payment Obligations; and

            (iii) in the event that, notwithstanding the foregoing
         provisions of this Section 5(d), any payment of any kind or character,
         whether in cash, property or securities, shall be received by the
         Subordinated Lender on account of principal of this Demand Note before
         all Payment Obligations are paid in full in cash or in a manner
         satisfactory to the Senior Lender, or effective provisions made for
         its payment, such payment out of the proceeds from or distributions
         made under the Master Lease shall be received and held in trust for
         and shall be paid over to the Senior Lender in respect of Payment
         Obligations remaining unpaid or unprovided for or their representative
         under the agreements pursuant to which the Payment Obligations have
         been made, for application to the payment of such Payment





                                      C-3
<PAGE>   83
         Obligations until all such Payment Obligations shall have been paid in
         full in cash or in a manner satisfactory to the Senior Lender, after
         giving effect to any concurrent payment or distribution to the Senior
         Lender in respect of Payment Obligations.

         Without in any way modifying the provisions hereof or affecting the
subordination effected hereby if such notice is not given, DTAG shall give
prompt written notice to the Subordinated Lender of any dissolution, winding
up, liquidation or reorganization of DTAG (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors or
otherwise).

         6.      No Waiver; Amendment.  No failure or delay on the part of RCFC
in exercising any power or right hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such power or right preclude
any other or further exercise thereof or the exercise of any other power or
right.  No amendment, modification or waiver of, or consent with respect to,
any provision of this Demand Note shall in any event be effective unless (a)
the same shall be in writing and signed and delivered by DTAG and RCFC, and (b)
all consents required for such actions under the Related Documents shall have
been received by the appropriate Persons.

         7.      No Negotiation.  This Demand Note is not negotiable other than
a pledge or assignment to the Trustee, who is hereby authorized by DTAG and
RCFC to make claims for repayment of principal outstandings hereunder on behalf
of RCFC.

         8.      Successors and Assigns.  This Demand Note shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
permitted successors and assigns.

         9.      GOVERNING LAW.  THIS PROMISSORY NOTE HAS BEEN DELIVERED IN NEW
YORK, NEW YORK AND SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND GOVERNED BY
THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS
PRINCIPLES.

    (b)  If, notwithstanding the intent of the parties to this Lease, this
Lease is deemed by any court, tribunal, arbitrator or other adjudicative
authority in any proceeding (each, a "Court") to constitute a financing
arrangement or otherwise not to constitute a "true lease" with respect to the
Acquired Vehicles, then it is the intention of the parties that this Lease
together with the Master Collateral Agency Agreement, as such agreements apply
to the Acquired Vehicles, shall constitute a security agreement under
applicable law, and it is the intention of the parties that this Lease together
with the Master Collateral Agency Agreement, as such agreements apply to the
Financed Vehicles, shall in all events constitute a security agreement under
applicable law.  Each Lessee hereby acknowledges that it has granted to the
Master Collateral Agent, pursuant to the Master Collateral Agency Agreement,
for the benefit of the Trustee, a first priority security interest in all of

Collateral (as defined therein) as collateral security for the prompt and
complete payment and performance when due (whether at stated maturity, by
acceleration or otherwise) of all of the obligations and liabilities of such
Lessee to the Lessor and the Trustee, whether direct or indirect, absolute or
contingent, due or to become due, or now existing or hereafter incurred
(including interest accruing after the Lease Expiration Date and interest
accruing after the filing of any petition in bankruptcy, or the commencement of
any insolvency, reorganization or like proceeding), which may arise under, out
of, or in connection with, this Lease and any other document made, delivered or
given in connection herewith, whether on account of rent, principal, interest,
reimbursement obligations, fees, indemnities, costs, or expenses (including all
fees and disbursements of counsel to the Lessor or the Trustee that are
required to be paid by such Lessee pursuant to the terms hereof).

<PAGE>   10
    Section 2.1.  Leasing of Vehicles.  Subject to the terms and conditions
hereof, the Lessor agrees to lease to each Lessee and each Lessee agrees to
lease from the Lessor Vehicles in the Existing Fleet, as applicable, and each
additional Acquired Vehicle or Financed Vehicle identified in Vehicle order
summaries (each, a "Vehicle Order") produced from time to time by such Lessee,
listing Eligible Vehicles ordered by the Lessee for itself or as agent for the
Lessor, pursuant to the terms of any applicable Eligible Vehicle Disposition
Programs or otherwise.  The Lessor shall, subject to Section 4 and to
compliance with the terms of the Indenture, make available to the Lessees under
this Lease financing for Financed Vehicles (other than Texas Vehicles) in an
aggregate amount, and Acquired Vehicles and Texas Vehicles for lease to the
Lessees hereunder in an aggregate Net Book Value, which collectively shall not
exceed the Maximum Lease Commitment.  The applicable Lessee shall make
available to the Lessor (a) in the case of (i) any lease of Vehicles in the
Existing Fleet, (ii) the refinancing of any other Eligible Vehicle pursuant to
Section 2.3 of the Master Collateral Agency Agreement (collectively, together
with any Vehicles in the Existing Fleet to be leased under the Master Lease
(including, without limitation, any Vehicles previously subject to any other
Master Lease and refinanced pursuant to the Master Lease), "Refinanced
Vehicles"), and/or (iii) the refinancing of Eligible Receivables, a schedule as
set forth in Attachment A-1 hereto containing information concerning the
Refinanced Vehicles and the Eligible Receivables of a scope agreed upon by the
Lessor and such Lessee (a "Refinancing Schedule") , and (b) in the case of all
other Vehicles, a schedule containing the information with respect to the
Vehicles included within the Vehicle Order for such Vehicle as is set forth in
Attachment A-2 hereto, or in such form as is otherwise requested by the Lessor
(each, a "Vehicle Acquisition Schedule").  In addition, each Lessee shall
provide such other information regarding such Vehicles as the Lessor may
reasonably require from time to time.  The Lessor shall lease to the Lessees,
and the Lessees shall lease from the Lessor, only Vehicles that are Eligible
Vehicles.  This Lease, together with the Vehicle Disposition Programs and other
incentive programs relating to the Vehicles and any other related documents
attached to this Lease or submitted with a Vehicle Order or Refinancing
Schedule (collectively, the "Supplemental Documents"), will constitute the
entire agreement regarding the leasing of Vehicles by the Lessor to the
Lessees.

    Section 2.2.  Right of Lessees to Act as Lessor's Agent.  The Lessor agrees
that each Lessee may act as the Lessor's agent in placing Vehicle Orders on
behalf of the Lessor, as well as filing claims on behalf of the Lessor for
damage in transit, and other delivery related claims with respect to the
Vehicles leased hereunder; provided, however, that the Lessor may hold the
applicable Lessee liable for such Lessee's actions in performing as the
Lessor's agent hereunder.  In addition, the Lessor agrees that each Lessee may
make arrangements for delivery of Vehicles to a location selected by such
Lessee at such Lessee's expense.  Each Lessee or any related Sublessee, as
applicable, may accept or reject Eligible Vehicles upon delivery in accordance
with such Lessee's customary business practices, and any Eligible Vehicle, if
rejected, will be deemed a Casualty hereunder.  The applicable Lessee, acting
as agent for the Lessor, shall be responsible for pursuing any rights of the
Lessor with respect to the return of any Eligible Vehicle to the Manufacturer
thereof, or the applicable auction or dealer, as applicable, pursuant to the
preceding





                                      -4-
<PAGE>   11
sentence.  Each Lessee agrees that all vehicles ordered as provided herein
shall be Eligible Vehicles and shall be ordered utilizing the procedures
consistent with the applicable Vehicle Disposition Program or any guidelines of
the Manufacturer, auction or dealer, as applicable, for the ordering or
purchasing of Non-Program Vehicles, in each case as and to the extent
applicable.

    Section 2.3.  Payment of Purchase Price by Lessor.  Upon receipt of the
Manufacturer's invoice and certificate of origin in respect of any new Vehicle,
or such other customary documentation in respect of any used Vehicle, the
Lessor or its agent shall pay or cause to be paid to the auction, the dealer or
the related Manufacturer, as applicable, the costs and expenses incurred in
connection with the acquisition of such Vehicle under the applicable Vehicle
Disposition Program (in the case of a Program Vehicle) or otherwise (in the
case of a Non-Program Vehicle) as established by the invoice of the auction,
the dealer or the Manufacturer, as the case may be (the "Initial Acquisition
Cost"), for such Vehicle and the applicable Lessee shall pay all applicable
costs and expenses of freight, packing, handling, storage, shipment and
delivery of such Vehicle to the extent that the same have not been included
within the Initial Acquisition Cost; provided that solely in the case of any
Vehicle in the Existing Fleet, any other Refinanced Vehicle, and any Eligible
Receivable, the Lessor shall pay to the Master Collateral Agent (x) the
aggregate Net Book Value as of the Vehicle Lease Commencement Date of the
Existing Fleet Vehicles, and/or the Refinanced Vehicles, as applicable,  and
(y) the face amount of the Eligible Receivables being refinanced on the Vehicle
Lease Commencement Date.

    Section 2.4.  Non-liability of Lessor.  The Lessor shall not be liable to a
Lessee for any failure or delay in obtaining Vehicles or making delivery
thereof.  AS BETWEEN THE LESSOR AND THE LESSEES, ACCEPTANCE FOR LEASE OF THE
VEHICLES SHALL CONSTITUTE THE APPLICABLE LESSEE'S ACKNOWLEDGMENT AND AGREEMENT
THAT THE APPLICABLE LESSEE HAS FULLY INSPECTED SUCH VEHICLES, THAT THE VEHICLES
ARE IN GOOD ORDER AND CONDITION AND ARE OF THE MANUFACTURE, DESIGN,
SPECIFICATIONS AND CAPACITY SELECTED BY SUCH LESSEE, THAT SUCH LESSEE IS
SATISFIED THAT THE SAME ARE SUITABLE FOR ITS USE AND THAT THE LESSOR IS NOT A
MANUFACTURER, AN AGENT OF THE MANUFACTURER OR OTHERWISE ENGAGED IN THE SALE OR
DISTRIBUTION OF VEHICLES, AND HAS NOT MADE AND DOES NOT HEREBY MAKE ANY
REPRESENTATION, WARRANTY OR COVENANT, EXPRESS OR IMPLIED, WITH RESPECT TO
MERCHANTABILITY, CONDITION, QUALITY, CAPABILITY, WORKMANSHIP, DURABILITY OR
SUITABILITY OF SUCH VEHICLES IN ANY RESPECT OR IN CONNECTION WITH OR FOR THE
PURPOSES OR USES OF SUCH LESSEE, OR ANY WARRANTY THAT THE LEASED VEHICLES WILL
SATISFY THE REQUIREMENTS OF ANY LAW OR ANY CONTRACT SPECIFICATION, OR ANY OTHER
REPRESENTATION, WARRANTY OR COVENANT OF ANY KIND OR CHARACTER, EXPRESS OR
IMPLIED, WITH RESPECT THERETO, AND AS BETWEEN THE LESSOR AND SUCH LESSEE, SUCH
LESSEE AGREES TO BEAR ALL SUCH RISKS AT ITS SOLE COST AND EXPENSE.  EACH LESSEE
SPECIFICALLY WAIVES ALL





                                      -5-
<PAGE>   12
RIGHTS TO MAKE CLAIMS AGAINST THE LESSOR AND ANY LEASED VEHICLE FOR BREACH OF
ANY WARRANTY OF ANY KIND WHATSOEVER AND, AS TO THE LESSOR, AND EACH LESSEE
LEASES THE LEASED VEHICLES "AS IS."  The Lessor shall not be liable for any
failure or delay in delivering any Vehicle ordered for lease pursuant to this
Lease, or for any failure to perform any provision hereof, resulting from fire
or other casualty, natural disaster, riot, strike or other labor difficulty,
governmental regulation or restriction, or any cause beyond the Lessor's direct
control.  IN NO EVENT SHALL THE LESSOR BE LIABLE FOR ANY INCONVENIENCES, LOSS
OF PROFITS OR ANY OTHER CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES,
WHATSOEVER OR HOWSOEVER CAUSED, WHETHER RESULTING FROM ANY DEFECT IN OR ANY
THEFT, DAMAGE, LOSS OR FAILURE OF ANY VEHICLE, OR OTHERWISE, AND THERE SHALL BE
NO ABATEMENT OF RENT BECAUSE OF THE SAME.

Commencement Date" shall mean, for each Vehicle, the earlier of (a) the date
referenced in the Vehicle Acquisition Schedule or Refinancing Schedule with
respect to such Vehicle, and (b) the date that funds are expended by the Lessor
to acquire or finance the acquisition of such Vehicle (with respect to such
Vehicle, the "Vehicle Funding Date").  A vehicle shall be deemed hereunder to
be a Vehicle leased under this Lease on each day during the period (the
"Vehicle Term") from and including the Vehicle Lease Commencement Date to but
excluding the Vehicle Lease Expiration Date.

all Series of Notes included in the Group II Series of Notes and all
outstanding Carrying Charges related thereto, and (ii) the Vehicle Lease
Expiration Date for the last Vehicle subject to lease by a Lessee hereunder.
The "Term" of this Lease shall mean the period commencing on the Lease

such Vehicles plus (b) the aggregate face amount of any related Eligible
Receivables being refinanced on such date.

    Section 6.2.  Information.  Each Lessee shall, from time to time upon the
Lessor's or the Trustee's reasonable request, deliver to the Lessor and the
Trustee copies of certificates describing all insurance required by Section 6.1
which is then in effect.

    SECTION 7.  CASUALTY OBLIGATION.  If a Vehicle becomes a Casualty, then the
applicable Lessee shall (a) promptly notify the Lessor of such occurrence, and
(b) in the case of an Acquired Vehicle, on the Due Date next succeeding the
last day of the Related Month in which the Lessee obtains actual knowledge that
such Vehicle has become a Casualty, pay to the Lessor an amount (a "Casualty
Payment") equal to the Net Book Value of such Vehicle, calculated as of the
earlier of the last day of such Related Month and the date such vehicle is
disposed of or becomes a Casualty, as applicable.  Upon payment by the
applicable Lessee to the Lessor in accordance herewith of the Casualty Payment
for any Acquired Vehicle that has become a Casualty, (i) the Lessor shall cause
title to such Vehicle to be transferred to such Lessee to facilitate
liquidation of such Vehicle by such Lessee, (ii) such Lessee shall be entitled
to any physical damage insurance proceeds applicable to such Acquired Vehicle
(if at such time such Lessee carries such insurance coverage), and (iii) the
Lien of the Master Collateral Agent on such Vehicle shall be released thereby.

    SECTION 8.  VEHICLE USE.  So long as no Lease Event of Default, Liquidation
Event of Default or Series 1998-1 Limited Liquidation Event of Default has
occurred, the Lessees may use Vehicles leased hereunder in the regular course
of their respective businesses, including subleasing such Vehicles to Eligible
Franchisees pursuant to Lessee Agreements, including Subleases, used in the
ordinary course of Lessees' businesses.  Notwithstanding any such Lessee
Agreement, the applicable Lessee shall remain fully liable for its obligations
under this Lease and the other Related Documents (including any obligation
hereunder or thereunder that it may cause any Franchisee to perform or
fulfill).  Each Lessee shall cause all payments under the Lessee Agreements, to
the extent such payments relate to vehicles comprising the Master Collateral,
to be deposited directly into the Master Collateral Account, and upon the
occurrence and during the continuance of a Lease Event of Default, Liquidation
Event of Default or Series 1998-1 Limited Liquidation Event of Default, the
Master Servicer shall promptly specify to the Master Collateral Agent the
allocation of such payments among Financing Sources.  Vehicle use shall be
confined primarily to the United States, with limited use outside the United
States; provided, however, that the principal place of business or rental
office of the Eligible Franchisee with respect to any Vehicles used outside the
United States shall be located in the United States.  Each Lessee shall
promptly and duly execute, deliver, file and record all such documents,
statements, filings and registrations, and take such further actions as the
Lessor, the Master Collateral Agent, the Master Servicer or the Trustee shall
from time to time reasonably request in order to establish, perfect and
maintain the Lessor's title to and interest in the Acquired Vehicles and the
related Certificates of Title as against such Lessee or any third party in any
applicable jurisdiction and to establish, perfect and maintain the Master
Collateral Agent's Lien on the Vehicles and the related Certificates of Title
(other than recordation of liens with respect to the Existing Fleet) as a
perfected lien in any applicable jurisdiction.  Each Lessee may, at such
Lessee's sole expense, change the place of principal location of any Vehicles.
After any such change of location, the applicable Lessee shall take all actions
necessary (i) to maintain the Lien of the Master Collateral Agent on such
Vehicles and the Certificates of Title with respect to such Vehicles (other
than recordation of liens with respect to the Existing Fleet), and (ii) to meet
or





                                      -10-
<PAGE>   17
obtain all material legal requirements applicable to such Vehicles.  Following
a Lease Event of Default or Manufacturer Event of Default, and upon the
Lessor's request, each Lessee shall advise the Lessor in writing where all
Vehicles leased by such Lessee hereunder as of such date are principally
located.  The Lessees shall not knowingly use any Vehicles, or knowingly permit
the same to be used, for any unlawful purpose.  The Lessees shall and shall
require the related Franchisees to use reasonable precautions to prevent loss
or damage to Vehicles.  The Lessees shall or shall cause the related
Franchisees to comply with all applicable statutes, decrees, ordinances and
regulations regarding acquiring, titling, registering, leasing, insuring and
disposing of Vehicles and shall or shall require such related Franchisees to
take reasonable steps to ensure that operators are licensed.  The Lessees shall
or shall cause the related Franchisees to perform, at its or their own expense,
such vehicle preparation and conditioning services with respect to Vehicles as
are customary.  The Lessor, the Master Collateral Agent or the Trustee or any
authorized representative of the Lessor, the Master Collateral Agent or the
Trustee may during reasonable business hours from time to time, without
disruption of the applicable Lessee's or the related Franchisee's business,
subject to applicable law, inspect Vehicles and registration certificates,
Certificates of Title and related documents covering Vehicles wherever the same
be located.

    SECTION 9.  REGISTRATION; LICENSE; TRAFFIC SUMMONSES; PENALTIES AND FINES.
Each Lessee, at its expense, shall be responsible for proper registration and
licensing of the Vehicles leased by it hereunder, and the titling of such
Vehicles in the name of the Lessor (in the case of Acquired Vehicles and Texas
Vehicles) or the Lessor or such Lessee, as applicable (in the case of Financed
Vehicles and Vehicles in the Existing Fleet), in each case with the Lien of the
Master Collateral Agent noted thereon (other than with respect to the Existing
Fleet), and where required, each Lessee shall or shall cause the related
Franchisees to have Vehicles inspected by any appropriate governmental
authority; provided, however, that notwithstanding the foregoing, unless a
Liquidation Event of Default shall have occurred and be continuing, possession
of all Certificates of Title shall remain with each Servicer of the related
Vehicles or the Master Servicer with such Certificates of Title to be held in
trust, as agent of and custodian for the Master Collateral Agent.  Each Lessee
shall pay or cause to be paid all registration fees, title fees, license fees,
traffic summonses, penalties, judgments and fines incurred with respect to any
Vehicle leased hereunder by such Lessee during the Vehicle Term for such
Vehicle or imposed during the Vehicle Term for such Vehicle by any governmental
authority or any court of law or equity with respect to Vehicles in connection
with the Lessee's operation of Vehicles, and any such amounts paid by the
Lessor, in its discretion, on such Lessee's behalf will be reimbursed within
thirty (30) days of the Lessor notifying the Lessee of such payment.  The
Lessor agrees to execute a power of attorney substantially in the form of
Attachment B hereto (a "Power of Attorney"), and such other documents as may be
necessary in order to allow each Lessee to title, register and dispose of the
Acquired Vehicles and Texas Vehicles leased by such Lessee hereunder; and each
Lessee acknowledges and agrees that with respect to the Acquired Vehicles, it
has no right, title or interest in or with respect to any





                                      -11-
<PAGE>   18
Certificate of Title.  Notwithstanding anything herein to the contrary, the
Lessor may terminate such Power of Attorney as provided in Section 17.3.

    SECTION 10.  MAINTENANCE AND REPAIRS.  Each Lessee shall or shall cause the
related Franchisees, as applicable, to pay for all maintenance and repairs to
keep the Vehicles leased by such Lessee hereunder in good working order and
condition, and shall or shall cause such Franchisees to maintain such Vehicles
as required in order to keep the Manufacturer's warranty in force.  Each Lessee
shall or shall cause the related Franchisees to return each Vehicle to an
authorized Manufacturer facility or the applicable Manufacturer's authorized
warranty station for warranty work.  Each Lessee shall or shall cause the
related Franchisees to comply with any Manufacturer's recall of any Vehicle.
Each Lessee shall or shall cause the related Franchisees to pay, or cause to be
paid, all usual and routine expenses incurred in the use and operation of
Vehicles including, but not limited to, fuel, lubricants, and coolants.  The
Lessor, upon thirty (30) days' prior written notice to the applicable Lessee,
may pay any such expenses that have not otherwise been paid by, or on behalf
of, such Lessee (including any failure by a related Franchisee to pay any such
expenses), and any expenses incurred by the Lessor on such Lessee's behalf for
maintenance, repair, operation or use of Vehicles by such Lessee will be
promptly reimbursed (in any event no later than the next monthly Due Date
following such payment) by such Lessee to the Lessor in the amount paid by the
Lessor.  Each Lessee shall not make any material alterations to any Vehicles
without the prior consent of the Lessor.  Any improvements or additions to any
Acquired Vehicle shall become and remain the property of the Lessor, except
that any addition or improvement to such a Vehicle made by a Lessee shall
remain the property of such Lessee if it can be disconnected or removed from
the Vehicle without impairing the functioning of or resale value thereof, other
than any function or value provided by such addition or improvement.

    SECTION 11.  VEHICLE WARRANTIES.  If a Vehicle is covered by a
Manufacturer's warranty, the applicable Lessee and each related Franchisee,
during the Vehicle Term, shall have the right to make any claims under such
warranty which the Lessor could make.  As provided in Section 2.4, the Lessor
makes no warranty or representation whatsoever, express or implied, with
respect to any Vehicle.

    SECTION 12.  VEHICLE USAGE REQUIREMENTS AND DISPOSITION.

    Section 12.1.  Usage.  As used herein, the term "vehicle turn-in condition"
with respect to each Program Vehicle leased hereunder by a Lessee means a set
of criteria for evaluating Program Vehicles upon their delivery at the end of
the applicable Vehicle Terms, which criteria will be determined in accordance
with the related Vehicle Disposition Program.  Each Program Vehicle leased
hereunder by a Lessee not meeting the applicable Vehicle Disposition Program's
vehicle turn-in condition requirements will, unless redesignated as a
Non-Program Vehicle in accordance with Section 14, be purchased by such Lessee
in accordance with the Casualty





                                      -12-
<PAGE>   19
procedure set forth in Section 7 or otherwise disposed of in accordance with
the late delivery procedure set forth in Section 13, as applicable.

    Section 12.2.  Disposition Procedure.  Prior to the end of the Vehicle
Term, each Lessee will or will cause the related Franchisee to deliver each
Program Vehicle leased hereunder by such Lessee (other than a Casualty) to the
nearest related Manufacturer official auction or other facility designated by
such Manufacturer at such Lessee's sole expense and in accordance with the
terms of the applicable Vehicle Disposition Program.  Any transportation
allowance (for delivery costs) and any rebates or credits applicable to the
unexpired term of any license plates for a Vehicle shall inure to the benefit
of and, upon receipt thereof by the Lessor, the Trustee or the Master
Collateral Agent, shall promptly be paid over to the applicable Lessee.  Each
Lessee will comply with the requirements of law and the requirements of the
Vehicle Disposition Programs in connection with, among other things, the
delivery of Certificates of Title, documents of transfer signed as necessary,
signed Condition Reports, and signed odometer statements for the Program
Vehicles.

    Section 12.3.  Termination Payments.  On the Due Date next succeeding the
earlier of (a) the last day of the Related Month in which the Repurchase
Payment or the Guaranteed Payment, as the case may be, from a Manufacturer
pursuant to its Vehicle Disposition Program with respect to any Acquired
Vehicle that is a Program Vehicle, is received by the Lessor, the Master
Collateral Agent or the Trustee (including by deposit into the Collection
Account or the Master Collateral Account), and (b) the thirtieth (30th) day
after the expiration of the Maximum Term for such Vehicle, the Lessee that
leases such Vehicle hereunder shall pay to the Lessor in respect of such
Vehicle any Excess Damage Charges, Excess Mileage Charges, early turnback
surcharges and any other similar charges and penalties (collectively, a
"Program Vehicle Termination Payment") as determined by the Manufacturer or its
agent in accordance with the applicable Vehicle Disposition Program; and on the
Due Date next succeeding the earlier of (i) the last day of the Related Month
in which Disposition Proceeds from the sale or other disposition of an Acquired
Vehicle that is a Non-Program Vehicle, but is not a Casualty, are received by
the Lessor, the Master Collateral Agent or the Trustee (including by deposit
into the Collection Account or the Master Collateral Account), and (ii) the
thirtieth (30th) day after the date which is twenty- four (24) months after the
date of the original new dealer invoice for such Vehicle, the applicable Lessee
shall pay to the Lessor in respect of such Vehicle an amount (a "Non-Program
Vehicle Termination Payment") equal to the quotient of (x) the sum of all
Program Vehicle Termination Payments for the Related Month in respect of
Vehicles leased by such Lessee, divided by (y) the number of Acquired Vehicles
leased by such Lessee in respect of which such Program Vehicle Termination
Payments are payable (Program Vehicle Termination Payments and Non-Program
Vehicle Termination Payments being, collectively, "Termination Payments").  The
provisions of this Section 12.3 will survive the expiration or earlier
termination of the Term.

<PAGE>   20
    SECTION 13.  LATE RETURN PAYMENTS.  If an Acquired Vehicle which is a
Program Vehicle is not returned to the Manufacturer or accepted by the
Manufacturer in accordance with the related Vehicle Disposition Program prior
to the expiration of the Maximum Term for such Vehicle in accordance with
Section 12.2, the Lessee of such Vehicle hereunder shall, unless such Vehicle
has been redesignated as a Non-Program Vehicle in accordance with Section 14,
(a) promptly notify the Lessor of its failure to return such Vehicle to the
Manufacturer or to sell such Vehicle in accordance with the applicable Auction
Procedures during the Vehicle Term, (b) use commercially reasonable efforts to
sell or otherwise dispose of such Vehicle in a manner reasonably likely to
maximize proceeds from such disposition and consistent with industry practice,
(c) cause the Disposition Proceeds, if any, from any such sale or disposition
to be paid to the Master Collateral Agent, in accordance with paragraph 10(d)
of Annex A, and (d) on the Due Date next succeeding the earlier of (i) the last
day of the Related Month in which such Disposition Proceeds are received by the
Lessor, the Master Collateral Agent or the Trustee (including by deposit into
the Collection Account or the Master Collateral Account), and (ii) the
thirtieth (30th) day after the expiration of the Maximum Term for such Vehicle,
pay to the Lessor an amount (a "Late Return Payment") equal to the excess of
(x) the Net Book Value of such Vehicle, calculated as of the first day of the
calendar month in which such Maximum Term expired reduced by the Depreciation
Charges accrued with respect to such Vehicle through the date such Maximum Term
expired, over (y) the dollar amount of such Disposition Proceeds (which Late
Return Payment amount may be equal to, but not less than, zero dollars).  The
foregoing shall not affect the applicable Lessee's obligation to pay on the
related Due Date all Monthly Base Rent accrued with respect to each such
Vehicle through the date on which the Maximum Term for such Vehicle expires.

    SECTION 14.  REDESIGNATION OF VEHICLES.  (a) Upon a Program Vehicle's
becoming ineligible for repurchase by its Manufacturer or for sale in
accordance with applicable Auction Procedures, due to physical damage, repair
charges or accrued mileage, in each case in excess of that permitted under the
related Vehicle Disposition Program, or due to any failure or inability to
return such Vehicle to the Manufacturer or the designated auction site prior to
the expiration of the Maximum Term, or due to any other event or circumstance,
the applicable Servicer may designate such Vehicle as a Non-Program Vehicle if
such Vehicle, as a Non-Program Vehicle, will be an Eligible Vehicle and if
either (a) such designation meets the conditions of Section 4.2 or (b) the
Noteholders holding the requisite Invested Amount of each applicable Series of
Notes included in the Group II Series of Notes waive, in each case as and to
the extent permitted under the related Series Supplement, the requirements of
Section 4.2 as applied to this Section 14 and all such other conditions,
requirements or restrictions with respect to which a failure or violation has
occurred; provided, in each case, that (x) any additional Monthly Base Rent due
with respect to each such Vehicle, relating to the decrease, if any, of the Net
Book Value of such Vehicle under the newly applicable Depreciation Schedule,
shall be paid by the applicable Lessee on the next succeeding Due Date, and (y)
the minimum level of Enhancement required under the applicable Series
Supplement, after giving effect to such designation, shall be satisfied on the
date of designation.





                                      -14-
<PAGE>   21
    (b)  The applicable Servicer may designate a Non-Program Vehicle as a
Program Vehicle; provided, however, that (i) upon such redesignation and
through and including the applicable Vehicle Lease Expiration Date, such
Vehicle shall be an Eligible Vehicle, (ii) such Vehicle qualifies as an
Eligible Vehicle under the applicable Eligible Vehicle Disposition Program,
(iii) the Capitalized Cost, Net Book Value and Depreciation Charges with
respect to such Vehicle shall be recalculated as of the date of such
redesignation as if such Vehicle was a Program Vehicle at the time of the
initial related Vehicle Lease Commencement Date, and (iv) the related
Manufacturer has acknowledged such designation.  Upon any redesignation of a
Vehicle pursuant to this Section 14(b), (x) the Lessor shall advance to the
applicable Manufacturer the difference (if any) between the original
Capitalized Cost of such Vehicle and the Capitalized Cost of such Vehicle upon
redesignation, which amount shall be deemed to be part of the Initial
Acquisition Cost of such Vehicle and (y) the applicable Lessee shall be
entitled to a credit against the Monthly Base Rent due on the next succeeding
Due Date in an amount equal to the excess (if any) of the Net Book Value of
such Vehicle upon such redesignation over the original Net Book Value of such
Vehicle immediately prior to such redesignation.

    (c)  Any Financed Vehicle shall be redesignated as an Acquired Vehicle for
all purposes of this Lease, the Indenture and the Master Collateral Agency
Agreement, and shall become subject to the Operating Lease and shall cease to
be subject to the Financing Lease, upon the completion of the transfer
(including the re-registration of title ownership) of such Financed Vehicle to
the Lessor pursuant to the Limited Guarantee and Reimbursement Agreement.

    SECTION 15.  GENERAL INDEMNITY.

    Section 15.1.  Indemnity of the Lessor.  Each Lessee agrees to indemnify
and hold harmless the Lessor and the Lessor's directors, officers, agents and
employees (collectively, together with the Persons subject to indemnity under

    without limitation, any such Vehicle subleased to a Franchisee of such
    Lessee and any of the foregoing actions, events or circumstances occurring
    or arising in connection with such subleasing, any related Lessee

    interest thereon, whether assessed, levied against or payable by the Lessor
    or otherwise, with respect to any Vehicle leased by such Lessee hereunder
    or the acquisition, purchase, sale, lease, sublease, rental, use,

    thereto, and (ii) documentary, stamp, filing, recording, mortgage or other

    and

         Section 15.1.5.  such Lessee's Pro Rata Share of all out-of-pocket
    costs and expenses (including reasonable attorneys' fees and legal

                                      -16-
<PAGE>   23
    Notwithstanding the foregoing, no Lessee shall have any duty to indemnify
any Indemnified Person for any consequential or punitive damages or claims,
demands, liabilities, costs, or expenses to the extent such claim, demand,
liability, cost or expense arises out of or is due to such Indemnified Person's
gross negligence or willful misconduct.

    Section 15.2.  Indemnification of the Trustee.  Each Lessee agrees to
indemnify and hold harmless the Trustee and the Trustee's officers, directors,
agents and employees against any and all or, in the case of clause (ii) below,

whatsoever nature, and all or, in the case of clause (ii) below, such Lessee's
Pro Rata Share of all costs and expenses, relating to or in any way arising out
of:  (i) any acts or omissions of such Lessee pursuant to this Lease and (ii)
the Trustee's appointment under the Base Indenture and the Trustee's
performance of its obligations thereunder, or any document pertaining to any of
the foregoing to which the Trustee is a signatory, including, but not limited
to any judgment, award, settlement, reasonable attorneys' fees and other costs
or expenses incurred in connection with the defense of any actual or threatened

Section 15.2,  to the extent such claim, demand, liability, cost or expense
arises out of or is due to the Trustee's or such Indemnified Person's gross
negligence or willful misconduct.  Any such indemnification shall not be
payable from the assets of the Lessor.  The provisions of this indemnity shall
run directly to and be enforceable by the Trustee or any other Indemnified
Person subject to the limitations hereof.  The indemnification provided for in
this Section 15.2 shall be in addition to any other indemnities available to
the Trustee and shall survive the termination of the duties of the Lessees
hereunder and the termination of this Lease or a document to which the Trustee
is a signatory or the resignation or removal of the Trustee.

Lease, such Lessee shall be subrogated to the rights of the Lessor or the
Trustee, as the case may be, in the affected transaction and shall have a right
to determine the settlement of claims therein.  The foregoing indemnity as
contained in this Section 15 shall survive the expiration or earlier
termination of this Lease or any lease of any Vehicle hereunder; provided,
however, that the factual or legal circumstances giving rise to the Lessor's
exposure to liability occur during the period that the Lease is in effect as to
the Vehicle for which such exposure to liability arose.

    Section 15.4.  Notice to Lessee of Claims.  The Lessor or the Trustee, as
the case may be, shall notify the applicable Lessee in writing (a "Notice of
Claim") of the pendency of any such claim, action or facts referred to in this
Section 15 for which indemnity may be required.

    Section 15.5.  Defense of Claims.  Defense of any claim referred to in this
Section 15 for which indemnity may be required shall, at the option and request
of the applicable Lessee, be conducted by such Lessee.  Following receipt of
any Notice of Claim, such applicable Lessee will inform the Indemnified Person
of its election to defend such claim.  Such Indemnified Person may participate
in any such defense at its own expense, provided such participation does not
interfere with such Lessee's defense.  Each Lessee agrees that no Indemnified
Person will be liable to such Lessee for any claim caused directly or
indirectly by the inadequacy of any Vehicle for any purpose or any deficiency
or defect therein or the use or maintenance thereof or any repairs, servicing
or adjustments thereto or any delay in providing or failure to provide such or
any interruption or loss of service or use thereof or any loss of business, all
of which shall be the risk and responsibility of such Lessee, except to the
extent that any of the foregoing is caused by the gross negligence or willful
misconduct of such Indemnified Person.  The rights and indemnities of each
Indemnified Person hereunder are expressly made for the benefit of, and will be
enforceable by, each Indemnified Person notwithstanding the fact that such
Indemnified Person is not or is no longer a party to (or entitled to receive
the benefits of) this Lease.  This general indemnity shall not affect any
claims of the type discussed above which a Lessee may have against the
Manufacturer.

    SECTION 16.  ASSIGNMENT.  No Lessee shall, except as provided in the Base
Indenture, without prior written consent of the Lessor and the Trustee, assign
this Lease or any of its rights hereunder to any other party; provided,
however, a Lessee may sublease or rent Vehicles leased by it under the terms of
such Lessee's normal Sublease agreements to Eligible Franchisees, and such
Lessee and such Eligible Franchisees may rent such Vehicles to consumers in the
ordinary course of their daily rental business.  Any purported assignment in
violation of this Section 16 shall be void and of no force or effect.  Nothing
contained herein shall be deemed to restrict the right of a Lessee to acquire
or dispose of, by purchase, lease, financing, or otherwise, motor vehicles that
are not subject to the provisions of this Lease.

    Section 17.1.  Lease Events of Default.  Any one or more of the following
will constitute an event of default (a "Lease Event of Default") as that term
is used herein:

    Base Rent, Monthly Variable Rent, Monthly Finance Rent, Termination
    Payment, Casualty Payment, Late Return Payment, Monthly Supplemental
    Payment, Availability Payment or other amount payable under this Lease, and
    the continuance thereof for three (3) Business Days with respect to any

<PAGE>   25
    to any other amounts, in each case after notice thereof by the Lessor, the
    Master Collateral Agent or the Trustee to the applicable Lessee and the
    Guarantor;

         Section 17.1.2.  any unauthorized assignment or transfer of this Lease
    by a Lessee or the Guarantor occurs;

         Section 17.1.3.  the failure of a Lessee or the Guarantor to observe
    or perform any other covenant, condition, agreement or provision hereof,
    which failure has a Material Adverse Effect on the Lessor, and such default
    continues for more than sixty (60) days after the earlier to occur of (a)
    the date a Responsible Officer of such Lessee obtains knowledge of such
    default or (b) the date written notice thereof is delivered by the Lessor,
    the Master Collateral Agent or the Trustee to such Lessee; provided,
    however, that if such failure cannot reasonably be cured within such sixty
    (60) day period, no Lease Event of Default shall result therefrom so long
    as, within such sixty (60) day period, such Lessee (i) commences to cure
    same, (ii) delivers written notice to the Lessor, the Master Collateral
    Agent and the Trustee notifying the Lessor, the Master Collateral Agent and
    the Trustee of such default and setting forth the steps such Lessee intends
    to take in order to cure such default and (iii) thereafter diligently
    prosecutes such cure to completion and completely cures such default on or
    before the ninetieth (90th) day after the earlier of the dates set forth in
    clause (a) and clause (b) above;

         Section 17.1.4.  if any representation or warranty made by a Lessee or
    the Guarantor proves untrue in any respect as of the date of the issuance
    or making thereof, which inaccuracy or falsehood has a Material Adverse
    Effect on the Lessor, and such inaccuracy or falsehood is not cured within
    sixty (60) days after notice thereof from the Lessor, the Master Collateral
    Agent or the Trustee to such Lessee;

         Section 17.1.5.  an Event of Bankruptcy occurs with respect to a
    Lessee or the Guarantor; or

         Section 17.1.6.  a Series 1998-1 Enhancement Deficiency shall occur
    and continue for at least one (1) Business Day after the Master Servicer
    obtains actual knowledge thereof; provided, however, that such event or
    condition shall not be a Lease Event of Default if within such one (1)
    Business Day period DTAG shall have taken any of the actions described in
    the proviso to Section 5.1(a) of the Series 1998-1 Supplement such that the
    Series 1998-1 Enhancement Deficiency no longer exists and such action is in
    accordance with the terms of Section 4.7(d)(v) of the Series 1998-1
    Supplement.

    Section 17.2.  Effect of Lease Event of Default.  If (i) a Lease Event of
Default described in Section 17.1.1(i), 17.1.2 or 17.1.5 shall occur, then the
Monthly Base Rent, the Monthly Supplemental Payment and Casualty Payments (in
each case calculated as if all Vehicles had become a Casualty for the Related
Month), the Monthly Variable Rent, the Availability Payment





                                      -19-
<PAGE>   26
and the Monthly Finance Rent (in each case calculated as if the full amount of
interest, principal and other charges under all Outstanding Series of Notes
included in the Group II Series of Notes were then due and payable in full),
Termination Payments and Late Return Payments shall, automatically, without
further action by the Lessor or the Trustee, become immediately due and payable
or (ii) any other Lease Event of Default or any Liquidation Event of Default
shall occur, the Lessor or the Trustee may declare the Rent and all other
charges and payments (calculated as described in clause (i) above) to be due
and payable, whereupon such Rent and such other charges and payments (as so
calculated) shall, subject to Section 17.5, become immediately due and payable.

    Section 17.3.  Rights of Lessor Upon Lease Event of Default, Liquidation
Event of Default or Limited Liquidation Event of Default.  If a Lease Event of
Default, Liquidation Event of Default or Limited Liquidation Event of Default
shall occur, then the Lessor at its option may:

         (i)  Proceed by appropriate court action or actions, either at law or
    in equity, to enforce performance by the Lessees of the applicable
    covenants and terms of this Lease or to recover damages for the breach
    hereof calculated in accordance with Section 17.5; or

         (ii)  By notice in writing to each Lessee, terminate this Lease in its
    entirety and/or the right of possession hereunder of the Lessees as to the
    Vehicles, and the Lessor may direct delivery by the Lessees of documents of
    title to the Vehicles, whereupon all rights and interests of the Lessees to
    the Vehicles (except as otherwise provided herein) will cease and terminate
    (but the Lessees will remain liable hereunder as herein provided,
    calculated in accordance with Section 17.5); and thereupon, the Lessor or
    its agents may, subject in each case to the rights of the Franchisees under
    the applicable Subleases, peaceably enter upon the premises of the Lessees
    or other premises where the Vehicles may be located and take possession of
    them and thenceforth hold, possess and enjoy the same free from any right
    of the Lessees, or their successors or assigns (other than the
    Franchisees), to employ the Vehicles for any purpose whatsoever consistent
    with the mitigation of losses and damages, and the Lessor will,
    nevertheless, have a right to recover from the Lessees any and all amounts
    which under the terms of Section 17.2 (as limited by Section 17.5) of this
    Lease may be then due.  The Lessor will provide the applicable Lessee with
    written notice of the place and time of any sale of Financed Vehicles
    pursuant to this Section 17.3 at least five (5) days prior to the proposed
    sale, which shall be deemed commercially reasonable, and such Lessee or the
    Lessor may purchase the Vehicle(s) at the sale.  Each and every power and
    remedy hereby specifically given to the Lessor will be in addition to every
    other power and remedy hereby specifically given or now or hereafter
    existing at law, in equity or in bankruptcy and each and every power and
    remedy may be exercised from time to time and simultaneously and as often
    and in such order as may be deemed expedient by the Lessor; provided,
    however, that the measure of damages recoverable against a Lessee will in
    any





                                      -20-
<PAGE>   27
    case be calculated in accordance with Section 17.5.  All such powers and
    remedies will be cumulative, and the exercise of one will not be deemed a
    waiver of the right to exercise any other or others.  No delay or omission
    of the Lessor in the exercise of any such power or remedy and no renewal or
    extension of any payments due hereunder will impair any such power or
    remedy or will be construed to be a waiver of any default or any
    acquiescence therein.  Any extension of time for payment hereunder or other
    indulgence duly granted to a Lessee will not otherwise alter or affect the
    Lessor's rights or the obligations hereunder of such Lessee.  The Lessor's
    acceptance of any payment after it will have become due hereunder will not
    be deemed to alter or affect the Lessor's rights hereunder with respect to
    any subsequent payments or defaults therein; or

         (iii)  By notice in writing to a Lessee, terminate the Power of
    Attorney of such Lessee.

    Section 17.4.  Rights of Trustee Upon Liquidation Event of Default, Limited
Liquidation Event of Default, Manufacturer Event of Default and Non-Performance
of Certain Covenants.

         (i)  If a Liquidation Event of Default or a Limited Liquidation Event
    of Default or, with respect to Program Vehicles, a Manufacturer Event of
    Default, shall have occurred and be continuing, the Lessor and the Trustee,
    to the extent provided in the Indenture, shall have the rights against the
    Guarantor, each Lessee, each Manufacturer in connection with any
    Manufacturer Event of Default and the Master Lease Collateral provided in
    the Indenture (including, without limitation, in connection with a
    Manufacturer Event of Default, the rights granted under Section 8.2 of the
    Indenture) upon a Liquidation Event of Default or Limited Liquidation Event
    of Default, including the right to take possession of all Group II Vehicles
    immediately from the Lessees.

         (ii)  With respect to Program Vehicles, if the Guarantor or any Lessee
    shall default in the due performance and observance of any of its
    obligations under Section 6.1, 23.4, 24.3, 24.4 (f), 24.7 or 25.4 hereof,
    and such default shall continue unremedied for a period of 30 days after
    notice thereof shall have been given to the Guarantor or the applicable
    Lessee, as the case may be, by the Lessor, the Lessor or the Trustee, as
    assignee of the Lessor's rights hereunder, shall have the ability to
    exercise all rights, remedies, powers, privileges and claims of the
    Guarantor or any Lessee against the Manufacturers under or in connection
    with the Eligible Vehicle Disposition Programs with respect to (i) Group II
    Vehicles that are Program Vehicles which the Guarantor or any Lessee has
    determined to turn back to the Manufacturers under such Eligible Vehicle
    Disposition Programs and (ii) whether or not the Guarantor or any Lessee
    shall then have determined to turn back such Group II Vehicles that are
    Program Vehicles, any such Program Vehicles for which the applicable
    Maximum Term will expire within one week or less.

         (iii)  Upon a default in the performance (after giving effect to any
    grace periods provided herein) by the Guarantor or any Lessee of its
    obligations hereunder to keep the Group II Vehicles free of Liens and to
    maintain the Trustee's Lien perfected on the Master Lease Collateral, the
    Trustee shall have the right to take actions reasonably necessary to
    correct such default with respect to the subject Vehicles including the
    execution of UCC financing statements with respect to Eligible Vehicle
    Disposition Program and other general intangibles, and the  completion of
    Vehicle Perfection and Documentation Requirements on behalf of the
    Guarantor or any Lessee, as applicable.

         (iv)  Upon the occurrence of a Liquidation Event of Default or Limited
    Liquidation Event of Default, the Guarantor and each Lessee will return any
    Group II Vehicles that are Program Vehicles to the related Manufacturer in
    accordance with the instructions of the Lessor.

         (v)  Upon the occurrence of a Liquidation Event of Default or Limited
    Liquidation Event of Default, the Lessor shall have the right to dispose of
    (x) those Group II Vehicles that are Program Vehicles not accepted by the
    related Manufacturer under the applicable Eligible Program pursuant to
    clause (iv) above and (y) the Group II Vehicles that are Non-Program
    Vehicles and to direct the Guarantor or the applicable Lessee to dispose of
    such Vehicles in accordance with its instructions.  In addition, the Lessor
    shall have all of the rights, remedies, powers, privileges and claims
    vis-a-vis the Guarantor or any Lessee, necessary or desirable to allow the
    Trustee to exercise the rights, remedies, powers, privileges and claims
    given to the Trustee pursuant to Section 8.1 and, with respect to Program
    Vehicles, Section 8.2 of the Base Indenture and the Guarantor and each
    Lessee acknowledges that it has hereby granted to the Lessor all of the
    rights, remedies, powers, privileges and claims granted to the Trustee
    pursuant to Article 8 of the Base Indenture and that, under certain
    circumstances set forth in the Base Indenture, the Trustee may act in lieu
    of the Lessor in the exercise of such rights, remedies, powers, privileges
    and claims.

    Section 17.5.  Measure of Damages.  If a Lease Event of Default,
Liquidation Event of Default or Limited Liquidation Event of Default occurs and
the Lessor, the Master Collateral Agent or the Trustee exercises the remedies
granted to the Lessor, the Master Collateral Agent or the Trustee under this
Section 17 or under Section 8.2 of the Base Indenture, the amount that the
Lessor shall be permitted to recover shall be equal to:

         (i)  all Rent and payments under this Lease (calculated as provided in
    Section 17.2); plus

    connection; plus

         (iii)  all other amounts due and payable under this Lease; plus

         (iv)  interest from time to time on amounts due and unpaid under this

    of payment from the Manufacturers under Vehicle Disposition Programs, from
    sales of Vehicles to third parties, or otherwise), provided, however, that
    if a Financed Vehicle (other than a Texas Vehicle) is delivered to the
    Manufacturer or the designated auction site for repurchase by the
    Manufacturer under the applicable Vehicle Disposition Program or for sale
    in accordance with the applicable Auction Procedures, respectively, and
    such Vehicle is accepted for repurchase or sale by such Manufacturer (as
    evidenced by a Condition Report indicating that such Vehicle conforms to

Lessee becomes liable for the payment or reimbursement of any obligations,
claims or taxes pursuant to any provision hereof, such liability will continue,
notwithstanding the expiration or termination of this Lease, until all such
amounts are paid or reimbursed by such Lessee.

    SECTION 21.  RIGHTS OF LESSOR PLEDGED TO MASTER COLLATERAL AGENT AND
TRUSTEE.  Notwithstanding anything to the contrary contained in this Lease,
each Lessee and the Guarantor acknowledges that each of the Lessees and the
Lessor, pursuant to the Master Collateral Agency Agreement, has granted a
security interest to the Master Collateral Agent, for the benefit of the

<PAGE>   31
Account and the other Collateral described in the Indenture.  Accordingly, each
Lessee and the Guarantor agrees that:

         (i)  Subject to the terms of the Indenture, the Trustee shall have all
    the rights, powers, privileges and remedies of the Lessor hereunder.
    Specifically, each Lessee and the Guarantor agrees that, upon the
    occurrence of an Amortization Event, the Trustee or, with respect to any
    Master Collateral, the Master Collateral Agent (for and on behalf of the
    Trustee) may exercise any right or remedy against each Lessee or the
    Guarantor provided for herein or in the Indenture or the Master Collateral
    Agency Agreement and none of the Lessees or the Guarantor will interpose as
    a defense that such claim should have been asserted by the Lessor;

         (ii)  Upon the delivery by the Master Collateral Agent or the Trustee
    of any notice to a Lessee or the Guarantor stating that a Lease Event of
    Default or an Amortization Event with respect to such Lessee has occurred,
    then such Lessee or the Guarantor will, if so requested by the Master
    Collateral Agent (with respect to the Master Collateral) or the Trustee
    (with respect to the Collateral), treat the Master Collateral Agent or the
    Trustee or the Master Collateral Agent's or the Trustee's designee, as the
    case may be, for all purposes as the Lessor hereunder and in all respects
    comply with all obligations under this Lease that are asserted by the
    Master Collateral Agent or the Trustee as the successor to the Lessor

         (iii) Pursuant to the Indenture, the Lessor hereby irrevocably
    authorizes and directs each Lessee to, and each Lessee shall, make payments
    of Rent hereunder directly to the Trustee for deposit in the Group II
    Collection Account established by the Trustee for receipt of such payments
    pursuant to the Indenture, and such payments shall discharge the obligation
    of such Lessee to the Lessor hereunder with respect to Rent to the extent
    of such payments.  Each Lessee further acknowledges that pursuant to the
    Master Collateral Agency Agreement, the Lessor has irrevocably authorized
    and directed such Lessee to, and such Lessee shall, cause all payments
    under the related Lessee Agreements, each Vehicle Disposition Programs, and
    all other Master Collateral pledged by such Lessee to the Master Collateral
    Agent for the benefit of the Trustee (as Beneficiary on behalf of the
    holders of each Series of Notes included in the Group II Series of Notes),
    to be made directly to the Master Collateral Agent for deposit in the
    Master Collateral Account established by the Lessor for receipt of such
    payments pursuant to the Master Collateral Agency Agreement, and each such
    payment (other than any payment that is subject to distribution to such
    Lessee or its designee pursuant to Section 2.5(b) of the Master Collateral
    Agency Agreement and that is not transferred to the Collection Account)
    shall constitute a prepayment in respect of the obligation of such Lessee
    to pay the Rent due hereunder on the next succeeding Due Date.  Upon
    written notice to a Lessee of a sale or assignment by the Trustee or Master
    Collateral Agent of its right, title and interest in





                                      -25-
<PAGE>   32
    moneys due under this Lease or the Master Collateral Agency Agreement to a
    successor Trustee or Master Collateral Agent, such Lessee shall thereafter
    make payments of Rent hereunder or payments in respect of the Master
    Collateral, as applicable, to the party specified in such notice;

         (iv)  Upon request made by the Master Collateral Agent at any time,
    each Lessee will take such actions (other than recordation of liens with
    respect to the Existing Fleet) as are requested by the Master Collateral
    Agent to assist the Master Collateral Agent in maintaining the Master
    Collateral Agent's perfected security interest in the Vehicles leased by
    such Lessee under this Lease, the Certificates of Title with respect
    thereto and the related Master Collateral pursuant to the Master Collateral
    Agency Agreement; and

         (v)  A security interest in the Lessor's rights under this Lease has
    been granted by the Lessor to the Trustee pursuant to the Indenture as
    collateral security only for all Series of Notes included in Group II and,
    accordingly, all references herein to "all" Series of Notes shall refer
    only to all Series of Notes included in Group II.

    SECTION 22.  MODIFICATION AND SEVERABILITY.  The terms of this Lease will
not be waived, altered, modified, amended, supplemented or terminated in any
manner whatsoever except by a written instrument signed by the Lessor, each
Lessee and (except as to matters referred to in Section 27.3) the Guarantor,
and consented to in writing by the Master Collateral Agent and the Trustee, the
Required Group II Noteholders and each Enhancement Provider with respect to
each Series of Notes included in Group II.  If any part of this Lease is not
valid or enforceable according to law, all other parts will remain enforceable.
The Lessor shall provide prompt written notice to each Rating Agency of any
such waiver, modification or amendment.

the Lessees and the Guarantor may, at any time and from time to time, without
the consent of the Master Collateral Agent, the Trustee,  any Noteholders or
any Enhancement Provider, enter into any amendment, supplement or other
modification to this Lease to cure any apparent ambiguity or to correct or

Series of Notes included in the Group II Series of Notes, based upon, at the
request of the Trustee, an Opinion of Counsel and an officers' certificate of
the Lessor and each Lessee addressed to the Trustee and (ii) a copy of such
amendment, supplement or other modification is furnished to the Trustee, each

    Section 23.4.  Liens.  As of the date hereof, there is no Lien on, or no

Indenture, all filings, registrations and recordings necessary or appropriate
to create, preserve, protect and perfect the security interest granted to the
Master Collateral Agent in respect of the Master Collateral (other than the
Vehicles in the Existing Fleet) have been accomplished and, assuming the
delivery to, and continuing possession by, the Lessor or its agents or
assignees of all instruments and documents (in each case as defined in the UCC
as in effect in New York) a security interest in which is perfected by
possession (except with regard to property constituting fixtures, any reserved
rights of the United States government as required by law, Liens upon patents,

extent that such Liens cannot be perfected by the filing of financing
statements under the Uniform Commercial Code as in effect in the applicable

actions under the laws of jurisdictions outside of the United States of
America, any State, territory or dependency thereof or the District of
Columbia, and Liens on general intangibles or accounts (in each case as defined
in the UCC as in effect in New York) on which the United States of America or
any department, agency, or instrumentality thereof is the obligor), and
assuming that the applicable Lessee has rights in the Master Collateral within
the meaning of the UCC as in effect in New York, the security interest granted
to the Master Collateral Agent pursuant to the Master Collateral Agency
Agreement in and to the Master Collateral (other than the Vehicles in the
Existing Fleet) constitutes a perfected security interest therein (but as to
the copyrights and copyright licenses and accounts arising therefrom, only to
the extent the UCC of the relevant jurisdiction, from time to time in effect,
is applicable), prior to the rights of all other Persons (except, with respect
to goods (as defined in the UCC), buyers in the ordinary course of business to
the extent provided in Section 9-307(1) of the UCC as from time to time in
effect in the applicable jurisdiction) therein and subject to no other Liens
other than Permitted Liens (and the interests of such buyers in the ordinary
course of business) and is entitled to all rights, priorities and benefits
afforded to perfected security interests by the UCC or other relevant law as
enacted in any relevant jurisdiction.

relate to the Lessees and the Lessor.  Each Lessee hereby agrees to maintain in
place all policies and procedures, and take and continue to take all actions,
described in the factual assumptions set forth in such opinion letter and

maintain any policy or procedure if and to the extent that such Lessee delivers

replacements, additions, betterment or improvements of or to, any tangible
property if such property, in its reasonable opinion, is obsolete or surplus or
unfit for use or cannot be used advantageously in the conduct of its business.

    Section 24.10.  Access to Certain Documentation and Information Regarding

tax imposed on or measured by income (or any interest or penalties with respect
thereto or arising from a failure to comply therewith), except to the extent
incurred as a result of a Servicer's violation of the provisions of this Lease
or of the Related Documents; provided, however, the foregoing provisions of
this sentence shall not affect the indemnification obligations of the Lessees
under Section 15 of this Lease.  In the event that a Servicer fails to pay any
amount due to the Trustee pursuant to Section 9.5 of the Base Indenture, the
Trustee will be entitled to receive such amounts due from the Monthly Servicing
Fee prior to payment thereof to such Servicer.

    SECTION 27.  GUARANTY.

    Section 27.1.  Guaranty.  In order to induce the Lessor to execute and
deliver this Lease and to lease Vehicles hereunder to the Lessees, and in
consideration thereof, the Guarantor hereby (i) unconditionally and irrevocably
guarantees to the Lessor the obligations of each of the Lessees to make any
payments required to be made by them under this Lease, (ii) agrees to cause
each Lessee to duly and punctually perform and observe all of the terms,
conditions, covenants, agreements and indemnities applicable to such Lessee
(whether in its capacity as a Lessee or as a Servicer) under this Lease, and
(iii) agrees that, if for any reason whatsoever, any Lessee (whether in its
capacity as a Lessee or as a Servicer) fails to so perform and observe such
terms, conditions, covenants, agreements and indemnities, the Guarantor will
duly and punctually perform and observe the same (the obligations referred to
in clauses (i) through (iii) above are collectively referred to as the
"Guaranteed Obligations").  The liabilities and obligations of the Guarantor
under the guaranty contained in this Section 27 (this "Guaranty") will be
absolute and unconditional under all circumstances.  This Guaranty shall be a
guaranty of payment and not of collection, and the Guarantor hereby agrees that
it shall not be required that the Lessor or the Trustee assert or enforce any
rights against any of the Lessees, the Servicers or any other person before or
as a condition to the obligations of the Guarantor pursuant to this Guaranty.

    Section 27.2.  Scope of Guarantor's Liability.  The Guarantor's obligations
hereunder are independent of the obligations of the Lessees (whether as Lessee
or as Servicer), any other guarantor or any other Person, and the Lessor may
enforce any of its rights hereunder independently of any other right or remedy
that the Lessor may at any time hold with respect to this Lease or any security
or other guaranty therefor.  Without limiting the generality of the foregoing,
the Lessor may bring a separate action against the Guarantor without first
proceeding against any of the Lessees, any other guarantor or any other Person,
or any security held by the Lessor, and regardless of whether the Lessees or
any other guarantor or any other Person is





                                      -43-
<PAGE>   50
joined in any such action.  The Guarantor's liability hereunder shall at all
times remain effective with respect to the full amount due from the Lessees
hereunder.  The Lessor's rights hereunder shall not be exhausted by any action
taken by the Lessor until all Guaranteed Obligations have been fully paid and
performed.

    Section 27.3.  Lessor's Right to Amend this Lease.  The Guarantor
authorizes the Lessor, at any time and from time to time without notice and
without affecting the liability of the Guarantor hereunder, to: (a) alter the
terms of all or any part of the Guaranteed Obligations and any security and
guaranties therefor including without limitation modification of times for
payment and rates of interest; (b) accept new or additional instruments,
documents, agreements, security or guaranties in connection with all or any
part of the Guaranteed Obligations; (c) accept partial payments on the
Guaranteed Obligations; (d) waive, release, reconvey, terminate, abandon,
subordinate, exchange, substitute, transfer, compound, compromise, liquidate
and enforce all or any part of the Guaranteed Obligations and any security or
guaranties therefor, and apply any such security and direct the order or manner
of sale thereof (and bid and purchase at any such sale), as the Lessor in its
discretion may determine; (e) release any Lessee, any guarantor or any other
Person from any personal liability with respect to all or any part of the
Guaranteed Obligations; and (f) assign its rights under this Guaranty in whole
or in part.

    Section 27.4.  Waiver of Certain Rights by Guarantor.  The Guarantor hereby
waives each of the following to the fullest extent allowed by law:

    (a)  any defense based upon:

                 (i)      the unenforceability or invalidity of any security or
                          other guaranty for the Guaranteed Obligations or the
                          lack of perfection or failure of priority of any
                          security for the Guaranteed Obligations; or

                 (ii)     any act or omission of the Lessor or any other Person
                          that directly or indirectly results in the discharge
                          or release of any of the Lessees or any other Person
                          or any of the Guaranteed Obligations or any security
                          therefor; provided that the Guarantor's liability in
                          respect of this Guaranty shall be released to the
                          extent the Lessor expressly releases such Lessee or
                          other Person, in a writing conforming to the
                          requirements of Section 22, from any Guaranteed
                          Obligations; or

                 (ii)     any payment by, or distribution of assets of, the
                          Guarantor or such Lessee of any kind or character,

                          such Lessee or the Guarantor would be entitled except
                          for this subordination shall be paid or delivered by
                          the Person making such payment or distribution,
                          whether a trustee in bankruptcy, a receiver or
                          liquidating trustee, or otherwise, directly to the
                          Trustee, for the benefit of the holders of the
                          Guaranteed Obligations to be held as additional
                          security for the Guaranteed Obligations in an
                          interest bearing account until the Guaranteed
                          Obligations have been paid in full; and

                 (iii)    if, notwithstanding the foregoing, any payment by, or
                          distribution of assets of, the Guarantor or such
                          Lessee of any kind or character, whether in cash,
                          property or securities, in respect of any
                          Subordinated Debt shall be received by such Lessee or
                          the Guarantor before the Guaranteed Obligations are
                          paid in full, such payment or distribution shall be
                          held in trust in an interest bearing account of the
                          Guarantor or such Lessee, as appropriate, and
                          immediately paid over in kind to the holders of the
                          Guaranteed Obligations until the Guaranteed
                          Obligations have been paid in full.

         (b)  The Guarantor authorizes and directs each Lessee and each Lessee
authorizes and directs the Guarantor to take such action as may be necessary or
appropriate to effectuate and maintain the subordination provided herein.

         (c)  No right of any holder of the Guaranteed Obligations to enforce
the subordination herein shall at any time or in any way be prejudiced or
impaired by any act or failure to act on the part of the Guarantor, any Lessee,
the Lessor or any other Person or by any noncompliance by the Guarantor, any
Lessee, the Lessor or any other Person with the terms, provisions and covenants
hereof or of the Related Documents regardless of any knowledge thereof that any
such holder of the  Guaranteed Obligations may have or be otherwise charged
with.

         (d)  Except as provided in Section 27.9, nothing express or implied
herein shall give any Person other than the Lessees, the Lessor, the Trustee
and the Guarantor any benefit or any legal or equitable right, remedy or claim
hereunder.

         (e)  If the Guarantor shall institute or participate in any suit,
action or proceeding against any Lessee or any Lessee shall institute or
participate in any suit, action or proceeding against the Guarantor, in
violation of the terms hereof, such Lessee or the Guarantor, as the case may
be, may interpose as a defense or dilatory plea this subordination, and the
holders of the Guaranteed

Obligations are irrevocably authorized to intervene and to interpose such
defense or plea in their name or in the name of such Lessee or the Guarantor,

expenses, including reasonable attorneys' and other professional and
paraprofessional fees, incurred by the Lessor (or the Trustee) in exercising
any right, power or remedy conferred by this Guaranty, or in the enforcement of
this Guaranty, whether or not any action is filed in connection therewith.
Until paid to the Lessor, such amounts shall bear interest, commencing with the
Lessor's demand therefor, for each Interest Period during the period from the
date of such demand until paid, at the VFR for such Interest Period plus 1%
(calculated on the basis of a 360-day year).

         Section 27.7.  Reinstatement.  This Guaranty shall continue to be
effective or be reinstated, as the case may be, if at any time payment of any
of the amounts payable by any Lessee under this Lease is rescinded or must
otherwise be restored or returned by the Lessor, upon an event of bankruptcy,
dissolution, liquidation or reorganization of any Lessee or the Guarantor or
upon or as a result of the appointment of a receiver, intervenor or conservator
of, or trustee or similar officer for, any Lessee, the Guarantor, any other
Guarantor or any other Person, or any substantial part of their respective
property, or otherwise, all as though such payment had not been made.

<PAGE>   64
         1.  Scope of Annex.  This Annex A shall apply only to the acquisition,
leasing and servicing of the Acquired Vehicles by the Lessor pursuant to the
Base Lease, as supplemented by this Lease Annex (collectively, the "Operating
Lease").

         2.  General Agreement.  With respect to the Acquired Vehicles, each
Lessee and the Lessor each intend that the Base Lease, as supplemented by this
Lease Annex, is an operating lease and that the relationship between the Lessor
and the Lessees pursuant thereto and hereto shall always be only that of lessor
and lessee, and each Lessee hereby declares, acknowledges and agrees that the
Lessor has title to and is the owner of the Acquired Vehicles.  The Lessees
shall not acquire by virtue of the Lease any right, equity, title or interest
in or to any Acquired Vehicles, except the right to use the same under the
terms of the Operating Lease hereof.  The parties agree that this Operating
Lease is a "true lease" for all legal, accounting, tax and other purposes and
agree to treat this Operating Lease, as it applies to the Acquired Vehicles, as
an operating lease for all purposes, including tax, accounting and otherwise.
The parties will file all federal, state and local tax returns and reports in a
manner consistent with the preceding sentence.

         3.  Operating Lease Commitment.  (a)  Upon the execution and delivery
of this Operating Lease, the Lessor shall, subject to the terms and conditions
of the Agreement, purchase from time to time on or after the Lease Commencement
Date and prior to the Lease Expiration Date, all Acquired Vehicles identified
in Vehicle Orders placed by a Lessee for a purchase price equal to the Initial
Acquisition Cost thereof, and simultaneously therewith, the Lessor shall under
the Operating Lease enter into operating leases with such Lessee with respect
to such Vehicles; provided, that the aggregate Net Book Value of Acquired
Vehicles leased hereunder on any date shall not exceed (a) the Maximum Lease
Commitment, less (b) the Base Amount as of such date with respect to the
Financing Lease.

         4.  Lease Procedures.  In connection with the Lease of any Acquired
Vehicles to be leased on or after the Lease Commencement Date, to evidence the
acquisition of such Acquired Vehicles by the Lessor, the applicable Lessee
shall deliver to the Lessor the following:

                 (a)  a Vehicle Order (including a Vehicle Acquisition
         Schedule) with respect to all Acquired Vehicles to be leased by such
         Lessee on the Lease Commencement Date;

                 (b)  UCC termination statements terminating, or UCC partial
         releases releasing, any security interests and other liens (other than
         Permitted Liens) in favor of any Person with respect to each Acquired
         Vehicle leased on the Lease Commencement Date and identified in such
         Vehicle Order, and any related Vehicle Disposition Programs;

                 (c)  with respect to the initial lease of Acquired Vehicles by
         such Lessee, a fully executed Assignment Agreement covering each
         Program Vehicle leased under this Annex A on the Lease Commencement
         Date or to be leased under this Annex A on any date





                                      -2-
<PAGE>   65
         thereafter, the related Vehicle Disposition Programs, and any other
         Master Collateral relating to such Vehicles.

         Each Lessee hereby agrees that each such delivery of a Vehicle Order
shall be deemed hereunder to constitute a representation and warranty by the
Lessee, to and in favor of the Lessor and the Trustee, that all the conditions
precedent to the acquisition and leasing of the Vehicles identified in such
Vehicle Order have been satisfied as of the date of such Vehicle Order.

         5.  Maximum Vehicle Lease Term.  The maximum Vehicle lease term of the
Operating Lease as it relates to each Acquired Vehicle leased hereunder shall
be from the Vehicle Lease Commencement Date to the date that is 24 months from
the date of the original new vehicle dealer invoice for such Acquired Vehicle.
On the occurrence of such date for a Vehicle not previously disposed of, the
applicable Lessee shall, (a) on behalf of the Lessor, promptly dispose of such
Vehicle in accordance with the terms hereof and in accordance with any
instructions of the Lessor for such disposition, (b) in each case, provide that
Disposition Proceeds be paid directly to the Master Collateral Account for the
benefit of the Trustee and (c) pay to the Master Collateral Agent or the
Trustee, in accordance with this Operating Lease, any other amounts unpaid and
owing from such Lessee under the Lease in respect of such Vehicle.

         6.  Lessee's Rights to Purchase Vehicles.  Each Lessee will have the
option, exercisable with respect to any Acquired Vehicle during the Vehicle
Term with respect to such Acquired Vehicle, to purchase any Vehicles leased by
it under the Lease at the Vehicle Purchase Price, in which event such Lessee
will pay the Vehicle Purchase Price to the Master Collateral Agent on or before
the Due Date next succeeding such purchase by the Lessee plus all accrued and
unpaid Monthly Base Rent and Monthly Variable Rent with respect to such Vehicle
through the date of such purchase.  In addition, each Lessee will have the
option, exercisable with respect to any Manufacturer Receivable related to an
Acquired Vehicle which was leased by such Lessee under this Lease, to purchase
such Manufacturer Receivable for a price equal to the amount due from the
Manufacturer under such Manufacturer Receivable, in which event the Lessee will
pay such amount to the Master Collateral Agent on or before the Payment Date
next succeeding such purchase by the Lessee.  Upon receipt of such funds by the
Master Collateral Agent, the Lessor, at the request of the Lessee, shall cause
title to any such Vehicle or Manufacturer Receivable, as applicable, to be
transferred to the applicable Lessee, and the lien of the Master Collateral
Agent on such Vehicle shall be released thereby.

         7.  Vehicle Disposition.  The Lessor and each Lessee agree that, with
respect to Acquired Vehicles, the applicable Lessee shall use its commercially
reasonable efforts to deliver each Program Vehicle leased by it under the Lease
for sale in accordance with the applicable Auction Procedures or to return such
related Program Vehicle to the related Manufacturer (a) not prior to the end of
the Minimum Term for such Vehicle, and (b) not later than the end of the
Maximum Term for such Vehicle; provided, however, if for any reason, such
Lessee fails to deliver such a Program Vehicle to the applicable Manufacturer
for repurchase by the Manufacturer or in





                                      -3-
<PAGE>   66
accordance with the applicable Auction Procedures, in each case in accordance
with the applicable Vehicle Disposition Program during the time period between
the expiration of the Minimum Term and the expiration of the Maximum Term, such
Lessee shall be obligated to sell or otherwise dispose of such Program Vehicle
and pay a Late Return Payment with respect thereto, in each case as provided in
Section 13 of the Base Lease.  Each Lessee shall, with respect to Acquired
Vehicles leased by it under this Operating Lease, pay the equivalent of the
Rent for the Minimum Term for Program Vehicles returned before the Minimum
Term, regardless of actual usage, unless such a Program Vehicle is a Casualty,
which will be handled in accordance with Section 7 of the Base Lease.  All
Disposition Proceeds, Repurchase Payments and Guaranteed Payments due from the
disposition of Program Vehicles pursuant to this Section shall be due and
payable to the Lessor.  The Lessor and each Lessee agree, with respect to
Acquired Vehicles, that such Lessee shall use its commercially reasonable
efforts to dispose of each Non-Program Vehicle leased to it under this
Operating Lease (a) in a manner most likely to maximize proceeds from such
disposition and consistent with industry practice and (b) within twenty-four
(24) months after the date of the original new vehicle dealer invoice for such
Vehicle.  All Disposition Proceeds due from the disposition of Non-Program
Vehicles pursuant to this Section shall be due and payable to the Lessor.

         8.  Lessor's Right to Cause Vehicles to be Sold.  Notwithstanding
anything to the contrary contained in the Lease, the Lessor shall have the
right, at any time after the date thirty (30) days prior to the expiration of
the Maximum Term for any Program Vehicle leased under this Annex A, to require
that the Lessee in respect of such Program Vehicle deliver such Program Vehicle
to the Manufacturer for repurchase or, as applicable, to the designated auction
site, or exercise commercially reasonable efforts to arrange for the sale of
such Program Vehicle to a third party for a price greater than the Net Book
Value thereof, in which event the Lessee shall, prior to the expiration of such
Maximum Term, deliver such Vehicle to its Manufacturer or the designated
auction site or arrange for the sale of such Program Vehicle to a third party
for a price greater than the Net Book Value (or purchase the Program Vehicle
itself from the Lessor for the Vehicle Purchase Price).  If a sale of the
Program Vehicle is arranged by a Lessee prior to the expiration of such Maximum
Term, then such Lessee shall deliver the Program Vehicle to the purchaser
thereof, the Lien of the Master Collateral Agent on the Certificate of Title of
such Program Vehicle shall be released, and such Lessee shall cause to be
delivered to the Lessor the funds paid for such Program Vehicle by the
purchaser.  If a Lessee is unable to arrange for a sale of the Program Vehicle
prior to the expiration of such Maximum Term, then such Lessee shall cease
attempting to arrange for such a sale and shall return such Program Vehicle to
the applicable Manufacturer or tender such Program Vehicle in accordance with
applicable Auction Procedures or purchase such Vehicle as herein provided.  In
no event may any Program Vehicle be sold pursuant to this paragraph 8 (other
than pursuant to a Vehicle Disposition Program) unless the funds to be paid to
the Lessor arising out of such sale exceed the Net Book Value of such Vehicle
less reasonably predictable Excess Mileage charges, Excess Damage Charges and
other similar charges imposed by the Manufacturer.

         9.  Calculation of Rent.  Rent shall be due and payable on a monthly
basis as set forth in this paragraph 9:

                 "Monthly Base Rent", with respect to each Due Date and each
         Acquired Vehicle leased under the Lease on any day during the Related
         Month, shall be the sum of all Depreciation Charges that have accrued
         with respect to such Vehicle during the Related Month.

                 "Monthly Variable Rent", with respect to each Due Date and
         each Acquired Vehicle leased under the Lease on any day during the
         Related Month, shall equal the sum, without double counting, of (a)
         the product of (i) an amount equal to the Net Book Value of such
         Acquired Vehicle on the first day contained within both the Related
         Month and the Vehicle Term with respect to such Vehicle multiplied by
         the VFR for the Interest Period ending on the next succeeding Payment
         Date and (ii) the quotient obtained by dividing (A) the number of days
         contained within both the Related Month and the Vehicle Term with
         respect to such Acquired Vehicle by (B) the total number of days in
         the Related Month plus (b) the product of (i) an amount equal to all
         Carrying Charges for the Related Month, and (ii) the quotient obtained
         by dividing the Net Book Value of such Acquired Vehicle as of the
         first day of the Related Month by the Net Book Value of all Vehicles
         leased under the Lease as of the first day of the Related Month.

                  "VFR", for any Interest Period with respect to any Group II
         Series of Notes, is an interest rate equal to the quotient, expressed
         as a percentage, of (i) the amount of interest accrued during such
         Interest Period with respect to all Group II Series of Notes divided
         by (ii) the average daily Aggregate Principal Balance of all such
         Group II Series of Notes during such period.

                 "Rent" means Monthly Base Rent plus Monthly Variable Rent.

         10.  Payment of Rent and Other Payments.

         Related Month with respect to all Vehicles that were leased by such
         Lessee under this Operating Lease on any day during the Related Month;

         Disposition Proceeds, Repurchase Payments, Guaranteed Payments and
         Incentive Payments payable in respect of Acquired Vehicles leased by
         it under this Operating Lease, to be paid directly to the Master
         Collateral Agent for the benefit of the Trustee.  The Servicer and the
         Lessees each agree that in the event that the Servicer or a Lessee
         shall receive directly any such payment, including cash, securities,
         obligations or other property, the Servicer or such Lessee, as the
         case may be, shall accept the same as the Master Collateral Agent's
         agent and shall hold the same in trust on behalf of and for the
         benefit of the Master Collateral Agent, and shall deposit the same,
         within two (2) Business Days after receipt thereof, into the Master
         Collateral Account in the same form received, with the endorsement of
         the Servicer or such Lessee, as the case may be, when necessary or
         appropriate.

         11.  Net Lease.  THE OPERATING LEASE SHALL BE A NET LEASE, AND EACH
LESSEE'S OBLIGATION TO PAY ALL RENT AND OTHER SUMS HEREUNDER SHALL BE ABSOLUTE
AND UNCONDITIONAL, AND SHALL NOT BE SUBJECT TO ANY ABATEMENT OR REDUCTION FOR
ANY REASON WHATSOEVER.  The obligations and liabilities of the Lessees
hereunder shall in no way be released, discharged or otherwise affected (except
as may be expressly provided herein including, without limitation, the right of
a Lessee to reject Vehicles pursuant to Section 2.2 of the Base Lease) for any
reason, including without limitation:  (i) any defect in the condition,
merchantability, quality or fitness for use of the Vehicles or any part
thereof; (ii) any damage to, removal, abandonment, salvage, loss, scrapping or
destruction of or any requisition or taking of the Vehicles or any part
thereof; (iii) any restriction, prevention or curtailment of or interference
with any use of the Vehicles or any part thereof; (iv) any defect in or any
Lien on title to the Vehicles or any part thereof; (v) any change, waiver,
extension, indulgence or other action or omission in respect of any obligation
or liability of a Lessee or the Lessor; (vi) any bankruptcy, insolvency,
reorganization, composition, adjustment, dissolution, liquidation or other like
proceeding relating to such Lessee, the Lessor or any other Person, or any
action taken with respect to this Operating Lease by any trustee or receiver of
any Person mentioned above, or by any court; (vii) any claim that such Lessee
has or might have against any Person, including without limitation the Lessor;
(viii) any failure on the part of the Lessor to perform or comply with any of
the terms hereof or of any other agreement; (ix) any invalidity or
unenforceability or disaffirmance of this Operating Lease or any provision
hereof or any of the other Related Documents or any provision of any thereof,
in each case whether against or by such Lessee or otherwise; (x) any insurance
premiums payable by such Lessee with respect to the Vehicles; or (xi) any other
occurrence whatsoever, whether similar or dissimilar to the foregoing, whether
or not such Lessee shall have notice or knowledge of any of the foregoing and
whether or not foreseen or foreseeable.  This Operating Lease shall be





                                      -6-
<PAGE>   69
noncancelable by any Lessee and, except as expressly provided herein, each
Lessee, to the extent permitted by law, waives all rights now or hereafter
conferred by statute or otherwise to quit, terminate or surrender this
Operating Lease, or to any diminution or reduction of Rent payable by the
Lessee hereunder.  All payments by a Lessee made hereunder shall be final
(except to the extent of adjustments provided for herein), absent manifest
error and, except as otherwise provided herein, no Lessee shall seek to recover
any such payment or any part thereof for any reason whatsoever, absent manifest
error.  If for any reason whatsoever this Operating Lease shall be terminated
in whole or in part by operation of law or otherwise except as expressly
provided herein, each Lessee shall nonetheless pay an amount equal to each Rent
payment at the time and in the manner that such payment would have become due
and payable under the terms of this Operating Lease as if it had not been
terminated in whole or in part.  All covenants and agreements of the Lessees
herein shall be performed at its cost, expense and risk unless expressly
otherwise stated.

         12.  Liens.  Except for Permitted Liens, each Lessee shall keep all
Acquired Vehicles leased by it free of all Liens arising during the Term.  Upon
the Vehicle Lease Expiration Date for each Acquired Vehicle leased hereunder,
the Lessor may, in its discretion, remove any such Lien and any sum of money
that may be paid by the Lessor in release or discharge thereof, including
reasonable attorneys' fees and costs, will be paid by the applicable Lessee
upon demand by the Lessor.  The Lessor may grant security interests in the
Acquired Vehicles without consent of the applicable Lessee; provided, however,
that if any such Liens would interfere with the rights of such Lessee under
this Operating Lease or any sublessee of such Lessee, the Lessor must obtain
the prior written consent of such Lessee.  Each Lessee acknowledges that the
granting of Liens and the taking of other actions pursuant to the Indenture and
the Related Documents does not interfere with the rights of such Lessee under
this Operating Lease.

         13.  Non-Disturbance.  So long as a Lessee satisfies its obligations
hereunder, its quiet enjoyment, possession and use of the Acquired Vehicles
will not be disturbed during the Term subject, however, to paragraph 8 of this
Annex A and except that the Lessor, the Master Collateral Agent and the Trustee
each retains the right, but not the duty, to inspect the Acquired Vehicles
without disturbing the ordinary conduct of such Lessee's business and except as
may be required as a consequence of a Liquidation Event of Default or Series
1998-1 Limited Liquidation Event of Default or certain optional prepayments of
a Series of Notes.  Upon the request of the Lessor, the Master Collateral Agent
or the Trustee, from time to time, each Lessee will make reasonable efforts to
confirm to the Lessor, the Master Collateral Agent and the Trustee the
location, mileage and condition of each Acquired Vehicle and to make available
for the Lessor's, the Master Collateral Agent's or the Trustee's inspection
within a reasonable time period, not to exceed forty-five (45) days, the
Acquired Vehicles leased by such Lessee at the location where the Acquired
Vehicles are normally located.  Further, each Lessee (and each related
Franchisee) will, during normal business hours and with a notice of three (3)
Business Days, make its records pertaining to such Acquired Vehicles available
to the Lessor, the Master





                                      -7-
<PAGE>   70
Collateral Agent or the Trustee for inspection at the location where such
Lessee's (and each such related Franchisee's) records are normally domiciled.

         14.  Certain Risks of Loss Borne by Lessees.  Upon delivery of each
Vehicle to a Lessee, as between the Lessor and such Lessee, such Lessee assumes
and bears the risk of loss, damage, theft, taking, destruction, attachment,
seizure, confiscation or requisition and all other risks and liabilities with
respect to such Vehicle, including personal injury or death and property
damage, arising with respect to any Vehicle due to the manufacturer, purchase,
acceptance, rejection, delivery, leasing, subleasing, possession, use,
inspection, registration, operation, condition, maintenance, repair or storage
of such Vehicle, howsoever arising.

         15.  Title.  This is an agreement to lease only, and title to the
Acquired Vehicles will at all times remain in the Lessor's name.  The Lessees
will not have any rights or interest in such Vehicles whatsoever other than the
rights of possession and use and the right to sublease such Vehicles as
provided by the Lease.  In addition, each Lessee, by its execution hereof,
acknowledges and agrees that (i) the Lessor is the sole owner and holder of all
right, title and interest in and to the Vehicle Disposition Programs as they
relate to the Vehicles leased hereunder and (ii) such Lessee has no right,
title or interest in any Vehicle Disposition Program as it relates to any
Vehicle leased hereunder.  To confirm the foregoing, each Lessee, by its
execution of the Base Lease of which this Annex A is a part, hereby assigns and
transfers to the Lessor any rights that such Lessee may have in respect of any
Vehicle Disposition Programs as they relate to the Vehicles leased hereunder.

         1.  Scope of Annex.  This Annex B shall apply only to the acquisition
or financing, leasing and servicing of the Financed Vehicles by RCFC pursuant
to the Base Lease, as supplemented by this Lease Annex (collectively, the
"Financing Lease").

         2.  General Agreement.  With respect to the Financed Vehicles, each
Lessee and the Lessor each intend that the Base Lease, as supplemented by this
Lease Annex, constitute a financing arrangement and the Lessor hereby declares,
acknowledges and agrees that the ownership of the Financed Vehicles rests
solely with such Lessee subject to the security interest granted hereunder to
the Lessor.

         3.  Financing Lease Commitment.  Subject to the terms and conditions

Vehicles identified in Vehicle Orders placed by a Lessee for an amount equal to
the Initial Acquisition Cost thereof, and in each case simultaneously therewith
enter into this Financing Lease with such Lessee with respect to the Existing
Fleet and other Financed Vehicles, as the case may be; provided, that the
aggregate outstanding Base Amount of the Financing Lease shall not on any date
exceed (a) the Maximum Lease Commitment, less (b) the sum of (x) the sum of the
Net Book Values of Acquired Vehicles leased under the Operating Lease on such
date, each such Net Book Value calculated as of the first day contained within

Vehicle Term for the related Acquired Vehicle, plus (y) accrued and unpaid
Monthly Base Rent under the Operating Lease as of such date.

         4.  Lease Procedures.

                 (a)  Initial Lease.  In connection with the lease of any
         Financed Vehicles to be leased on the Lease Commencement Date (or, in
         the case of an Additional Lessee, the date of the initial Vehicle
         Order or Refinancing Schedule thereof), to evidence the refinancing of
         Vehicles in the Existing Fleet and any other Refinanced Vehicles and

         Lessee on the Lease Commencement Date (or the date of such initial
         Vehicle Order) and the conveyance on such date of a security interest
         in such Financed Vehicles to the Master Collateral Agent, such Lessee
         shall deliver to the Lessor on or prior to the Lease Commencement Date

                 Vehicles to be leased by such Lessee on the Lease Commencement
                 Date (or date of the initial Vehicle Order of such Additional
                 Lessee, as applicable);

                       (ii)  a report of the results of a search of the
                 appropriate records of the county and state in which the
                 Refinanced Vehicles are located and the county and state in
                 which such Lessee's principal office is located, which shall
                 show no liens or other security interests (other than
                 Permitted Liens and the lien of Chrysler Financial Corporation
                 in the Existing Fleet) with respect to such Vehicles or, in
                 the event that such search reveals any such non-permitted Lien
                 or security interest, there shall be delivered to the Trustee
                 a termination of such Lien or security interest as provided
                 below;

                       (iii)  confirmation from any lender holding a security
                 interest in any Refinanced Vehicle stating unconditionally (A)
                 that, if any sums are to be paid to such lender in connection
                 with the lease of the Refinanced Vehicle, such lender has been
                 paid the full amount due to it in connection with such
                 refinancing and (B) that any lien or security interest of such
                 lender in such Vehicle has been released;

                       (iv)  UCC termination statements terminating, or UCC
                 partial releases releasing, any security interests and other
                 liens (other than Permitted Liens and the lien of Chrysler
                 Financial Corporation in the Existing Fleet) in favor of any
                 Person with respect to each Vehicle in the Existing Fleet
                 identified in such schedule and any related Vehicle
                 Disposition Programs;

                       (v)  fully executed Assignment Agreements from such
                 Lessee covering, as applicable, each Vehicle in the Existing
                 Fleet and each other Financed Vehicle leased by such Lessee on
                 the Lease Commencement Date or leased on any date thereafter
                 under the Lease, the related Vehicle Disposition Programs, and
                 any other Master Collateral relating to such Vehicles; and

                       (vi)  an Officer's Certificate for such Lessee stating
                 that all the conditions precedent under the Lease to the
                 leasing by such Lessee of such Vehicles on the Lease
                 Commencement Date have been satisfied.

                 (b)  Subsequent Leases.  In connection with each Lease of a
         Financed Vehicle after the Lease Commencement Date, to evidence the
         acquisition, financing or refinancing of such Financed Vehicle by the
         Lessor and the conveyance of a security interest in such Financed
         Vehicles to the Master Collateral Agent, each Lessee shall deliver to
         the Lessor a Vehicle Order (including a Vehicle Acquisition Schedule)
         or Refinancing Schedule with respect to all Financed Vehicles to be
         leased by such Lessee on the date specified therein.  Each Lessee
         hereby agrees that each such delivery of a





                                      -3-
<PAGE>   74
         Vehicle Order or Refinancing Schedule, as applicable, shall be deemed
         hereunder to constitute a representation and warranty by such Lessee,
         to and in favor of the Lessor and the Trustee, that all the conditions
         precedent to the acquisition or financing or refinancing and leasing
         of the Vehicles identified in such Vehicle Order or Refinancing
         Schedule, as applicable,  have been satisfied as of the date of such
         Vehicle Order or Refinancing Schedule.

         5.  Maximum Vehicle Lease Term.  The maximum Vehicle lease term of
this Financing Lease as it relates to each Financed Vehicle leased hereunder
shall be from the Vehicle Lease Commencement Date to the date that is 60 months
from the Vehicle Lease Commencement Date.  On the occurrence of such date, the
applicable Lessee shall pay to the Master Collateral Agent or the Trustee, in
accordance with this Financing Lease, any amounts unpaid and owing under the
Lease in respect of such Vehicle.

         6.  Calculation of Rent and Monthly Supplemental Payment.  Rent and
the Monthly Supplemental Payment shall be due and payable on a monthly basis as
set forth in this paragraph 6:

                 "Monthly Base Rent", with respect to each Due Date and each
         Financed Vehicle leased under the Lease on any day during the Related
         Month, shall be the sum of all Depreciation Charges that have accrued
         with respect to such Vehicle during the Related Month.

                 "Monthly Finance Rent", with respect to each Due Date and each
         Financed Vehicle leased under the Lease on any day during the Related
         Month, shall equal the sum, without double counting, of (a) the
         product of (i) an amount equal to the Net Book Value of such Financed
         Vehicle on the first day contained within both the Related Month and
         the Vehicle Term with respect to such Vehicle multiplied by the VFR
         for the Interest Period ending on the next succeeding Payment date and
         (ii) the quotient obtained by dividing (A) the number of days
         contained within both the Related Month and the Vehicle Term with
         respect to such Financed Vehicle by (B) the total number of days in
         the Related Month, plus (b) the product of (i) an amount equal to all
         Carrying Charges for the Related Month, and (ii) the quotient obtained
         by dividing the Net Book Value of such Financed Vehicle as of the
         first day of the Related Month by the Net Book Value of all Vehicles
         leased under the Lease as of the first day of the Related Month.

                 "Monthly Supplemental Payment" with respect to each Due Date
         and each Financed Vehicle shall be an amount equal to (a) the sum of,
         as applicable, (i) the aggregate amount of any Guaranteed Payment,
         Repurchase Payment, Disposition Proceeds and Incentive Payments
         received by the Lessor, the Master Collateral Agent or the Trustee
         (including by deposit into the Collection Account or the Master
         Collateral Account) during the Related Month with respect to such
         Vehicle, (ii) the amount of any





                                      -4-
<PAGE>   75
         unpaid Guaranteed Payment or unpaid Repurchase Payment with respect to
         such Vehicle becoming a Delinquent Guaranteed Payment or Delinquent
         Repurchase Payment, as the case may be, during the Related Month,
         (iii) the amount of any Disposition Proceeds with respect to such
         Vehicle becoming Delinquent Disposition Proceeds during the Related
         Month, (iv) the amount of any unpaid Incentive Payments with respect
         to such Vehicle becoming Delinquent Incentive Payments during the
         Related Month, (v) if such Vehicle becomes a Casualty or ceases to be
         an Eligible Vehicle (other than as a result of the sale or other
         disposition thereof), in each case during the Related Month, the Net
         Book Value of such Vehicle calculated as of the earlier of the last
         day of such Related Month and the date such Vehicle is disposed of or
         becomes a Casualty, as applicable, and (vi) if such Vehicle was
         returned to its Manufacturer for repurchase or sold to any Person or
         otherwise disposed of, in each case during the Related Month, the
         excess, if any, of (A) the Net Book Value of such Vehicle, calculated
         as of the applicable Vehicle Lease Expiration Date, over (B) the sum
         of all amounts (other than Incentive Payments) payable in respect of
         such Vehicle pursuant to clause (i) above, less (b) the excess, if
         any, of (i) the aggregate amount of Disposition Proceeds, Guaranteed
         Payments or Repurchase Payments, as applicable, from the sale or other
         disposition of such Vehicle received by the Lessor, the Master
         Collateral Agent or the Trustee (including by deposit into the
         Collection Account or the Master Collateral Account) during such
         Related Month over (ii) the Net Book Value of such Vehicle, calculated
         as of the applicable Vehicle Lease Expiration Date.

                 "Rent" means Monthly Base Rent plus Monthly Finance Rent.

                  "VFR", for any Interest Period with respect to any Group II
         Series of Notes, is an interest rate equal to the quotient, expressed
         as a percentage, of (i) the amount of interest accrued during such
         Interest Period with respect to all Group II Series of Notes, divided
         by (ii) the average daily Aggregate Principal Balance of all such
         Group II Series of Notes during such period.

         7.  Payment of Rent and Other Payments.  (a)  On each Due Date:

                 (i)  Monthly Base Rent.  Each Lessee shall pay to the Lessor
         the Monthly Base Rents that have accrued during the Related Month with
         respect to all Vehicles that were leased by such Lessee under this
         Finance Lease on any day during the Related Month; provided, however,
         that in the event that delinquent payments of Guaranteed Payments,
         Repurchase Payments, Disposition Proceeds and/or Incentive Payments
         are received by the Lessor, the Master Collateral Agent or the Trustee
         (including by deposit into the Collection Account or the Master
         Collateral Account) during the Related Month, such payments may be
         netted against the Monthly Base Rents to be paid on such Due Date to
         the extent (but only to the extent) that Monthly Base Rent has already
         been received by any of such Persons in respect of such delinquent
         payment obligations pursuant to any or

<PAGE>   76
         all of clauses (a)(ii), (iii) and (iv) of the definition of Monthly
         Supplemental Payment set forth in this Annex B;

                 (ii)  Monthly Finance Rent.  Each Lessee shall pay to the
         Lessor the Monthly Finance Rents that have accrued during the Related
         Month with respect to all Vehicles that were leased by such Lessee
         under this Finance Lease on any day during the Related Month.

                 (iii)  Monthly Supplemental Payments.  Each Lessee shall pay
         to the Lessor the Monthly Supplemental Payments that have accrued
         during the Related Month with respect to all Vehicles that were leased
         by such Lessee under this Finance Lease on any day during the Related
         Month; provided, however, that in the event that the Monthly
         Supplemental Payment accrued during a Related Month is a negative
         dollar amount, such amount may be netted against other payments to be
         paid on such Due Date pursuant to this paragraph 7.

         (b)  On the expiration of the term of the Lease with respect to a
Financed Vehicle, any remaining Base Amount, plus all other amounts payable by
each Lessee under this Financing Lease with respect to such Vehicle shall be
immediately due and payable.

         (c) Each Lessee may from time to time prepay the Base Amount of the
Financing Lease with respect to a Financed Vehicle, in whole or in part, on any
date, provided that such Lessee shall give the Lessor and the Trustee not less
than one (1) Business Day's prior notice of any prepayment, specifying the date
and amount of such prepayment, and the Financed Vehicles to which such
prepayment relates.

         8.  Risk of Loss Borne by Lessees.  Upon delivery of each Vehicle to a
Lessee, as between the Lessor and such Lessee, such Lessee assumes and bears
the risk of loss, damage, theft, taking, destruction, attachment, seizure,
confiscation or requisition with respect to such Vehicle, however caused or
occasioned, and all other risks and liabilities, including personal injury or
death and property damage, arising with respect to any Vehicle or the
manufacture, purchase, acceptance, rejection, ownership, delivery, leasing,
subleasing, possession, use, inspection, registration, operation, condition,
maintenance, repair, storage, sale, return or other disposition of such
Vehicle, howsoever arising.

         9.  Mandatory Purchase of Texas Vehicles.  Prior to the Vehicle Lease
Expiration Date with respect to each Texas Vehicle leased by a Lessee under
this Finance Lease (other than a Vehicle Lease Expiration Date arising in
connection with the purchase of such Texas Vehicle pursuant to this paragraph
9) and, in the case of each such Texas Vehicle which is a Program Vehicle,
prior to the expiration of the Maximum Term applicable thereto (unless such
Vehicle has been redesignated as a Non-Program Vehicle in accordance with
Section 14 of the Base Lease), such Lessee shall purchase such Texas Vehicle,
(including any such Vehicle which has





                                      -6-
<PAGE>   77
become a Casualty) at a purchase price equal to the Net Book Value of such
Vehicle calculated as of the date of purchase (or, in the case of a Casualty,
at a purchase price equal to the Monthly Supplemental Payments accruing in
respect of such Casualty during the Related Month in which such Vehicle became
a Casualty), which shall be payable to the Master Collateral Agent (together
with all accrued and unpaid Rent and other payments due and payable on such Due
Date with respect to such Texas Vehicle through the date of such purchase) on
or prior to the Due Date next succeeding such purchase by such Lessee.  The
Lessor shall cause title to each Texas Vehicle to be transferred to the
applicable Lessee, and the Servicer shall cause the Master Collateral Agent to
cause its Lien to be removed from the Certificate of Title for such Vehicle,
concurrently with or promptly after such purchase price for such Texas Vehicle
(and any such unpaid Rent and payments) is paid by such Lessee to the Master
Collateral Agent.  Notwithstanding anything to the contrary in the Lease, no
Texas Vehicle may be sold or otherwise disposed of (other than pursuant to
Section 17.3 of the Base Lease), including at Auction or by return to its
Manufacturer pursuant to a Vehicle Disposition Program, prior to its purchase
by a Lessee pursuant to and in accordance with this paragraph 9.

         10.  Lessee's Rights to Purchase Manufacturer Receivables.  In
addition, each Lessee will have the option, exercisable with respect to any
Manufacturer Receivable related to a Financed Vehicle which was leased by such
Lessee under this Lease, to purchase such Manufacturer Receivable for a price
equal to the amount due from the Manufacturer under such Manufacturer
Receivable, in which event the Lessee will pay such amount to the Master
Collateral Agent on or before the Payment Date next succeeding such purchase by
the Lessee.  Upon receipt of such funds by the Master Collateral Agent, the
Lessor, at the request of the Lessee, shall cause title to any such
Manufacturer Receivable to be transferred to the Lessee, the lien of the Master
Collateral Agent in such Manufacturer Receivable will automatically be released
concurrently with or promptly after the purchase price for such Manufacturer
Receivable (and any unpaid Monthly Base Rent, unpaid Monthly Variable Rent and
other unpaid charges, payments and amounts) is paid by the Lessee to the Master
Collateral Agent or the Trustee.

with the terms hereof, this "Agreement"), is made among RENTAL CAR FINANCE
CORP., an Oklahoma corporation ("RCFC"), DOLLAR THRIFTY AUTOMOTIVE GROUP, INC.,
a Delaware corporation ("DTAG" or the "Master Servicer"), and DOLLAR THRIFTY

                                   BACKGROUND

                 1.  Contemporaneously with the execution and delivery of this
Agreement, RCFC is entering into (a) the Series 1998-1 Supplement, dated as of
even date herewith (as the same may be amended, supplemented, restated or
otherwise modified from time to time in accordance with the terms thereof, the
"Series 1998-1 Supplement"), between RCFC, as Issuer, and Bankers Trust
Company, a New York banking corporation, as the Trustee (in such capacity,
together with its successors in trust in such capacity, the "Trustee"), and as
the Enhancement Agent (in such capacity, the "Enhancement Agent"), to the Base
Indenture, dated as of December 13, 1995 (as amended by the Amendment to Base
Indenture, dated as of December 23, 1997, and as the same may be further
amended, supplemented or otherwise modified from time to time in accordance
with the terms thereof, the "Base Indenture"), between RCFC and the Trustee,
and (b) the Master Motor Vehicle Lease and Servicing Agreement, dated as of
even date herewith (as the same may be amended, supplemented, restated or
otherwise modified from time to time in accordance with the terms thereof, the
"Master Lease") among RCFC, as lessor, the parties identified therein as the
Lessees and Servicers, those additional Subsidiaries of DTAG, from time to time
becoming Lessees and Servicers thereunder, and DTAG, as Guarantor and Master
Servicer, and (c) the other Related Documents (such term, as with the other
capitalized terms used herein, shall have the meaning assigned thereto in
Section 1.01 hereof) and CP Program Documents to which RCFC is a party.
Pursuant to the Base Indenture and the Series 1998-1 Supplement, RCFC will
issue the Rental Car Asset Backed Variable Funding Notes, Series 1998-1 (the
"Series 1998-1 Notes").

                 2.  RCFC wishes to issue the Series 1998-1 Notes in favor of
the Note Purchaser and obtain the agreement of the Note Purchaser to make loans
from time to time (each, an "Advance") for the purchase of Series 1998-1
Invested Amounts, all of which Advances (including the Initial Advance) will
constitute Increases, and all of which Advances (including the Initial Advance)
will be evidenced by the Series 1998-1 Notes purchased in connection herewith
and will constitute purchases of Series 1998-1 Invested Amounts corresponding
to the amount of such Advances.  Subject to the terms and conditions of this
Agreement, the Note Purchaser is willing to make Advances from time to time to
fund

purchases of Series 1998-1 Invested Amounts in an aggregate outstanding amount

herein contained, and for due and adequate consideration, which the parties
hereto hereby acknowledge, the parties hereto hereby agree as follows:

                                   ARTICLE II
                         PURCHASE AND SALE OF THE NOTES

                 SECTION 2.01  Purchases.  Subject to the terms and conditions
of this Agreement and the Series 1998-1 Supplement, the Note Purchaser shall
upon RCFC's request and satisfaction of all conditions precedent thereto, make
Advances from time to time during the Series 1998-1 Revolving Period, provided,
that (x) the Note Purchaser will not be required or permitted to make an
Advance on any date if, after giving effect to such Advance, the Series 1998-1
Invested Amount would exceed the Series 1998-1 Maximum Invested Amount, (y) the
Note Purchaser will not be required or permitted to make any Advance if, after
giving effect thereto and the use of proceeds therefrom, either (i) a Series
1998-1 Enhancement Deficiency exists or would exist, (ii) an Asset Amount
Deficiency exists or would exist or (iii) a CP Borrowing Base Deficiency exists
or would exist as determined by the Master Servicer.  All Advances on any date
shall be allocated (i) with respect to the Initial Advance, according to the
Series 1998-1 Initial Invested Amount; and (ii) thereafter, according to the
provisions in Section 4A.2 of the Series 1998-1 Supplement for allocating
Increases to the Series 1998-1 Invested Amount.  Each of the Advances to be
made on any date shall be made singly as part of a single borrowing (each such
single borrowing being a "Borrowing").  Subject to the terms of this Agreement
and the Series 1998- 1 Supplement, the aggregate principal amount of the
Advances represented by the Series 1998-1 Notes may be increased or decreased
from time to time.

                 SECTION 2.02  Borrowing Procedures.  Whenever RCFC wishes the
Note Purchaser to make an Advance, RCFC shall (or shall cause the Master
Servicer to) notify each of the Collateral Agent and the Trustee upon
irrevocable written notice delivered to the Collateral Agent and the Trustee no
later than the opening of business on the Business Day of the proposed
Borrowing (which Borrowing date shall, except in the case of the Initial
Advances, be an Increase Date).  Each such notice shall be irrevocable and
shall in each case refer to this Agreement and specify the aggregate amount of
the requested Borrowing to be made on such date (which Borrowing shall be in an
amount equal to at least $250,000 and, in the case of the Initial Advance only,
in an aggregate minimum amount of $1,000,000.  The Collateral Agent shall
promptly advise the Note Purchaser of any notice given pursuant to this
section, and promptly upon the Collateral Agent's receipt of notice from the
Note Purchaser on whether the Note Purchaser shall make such Advances shall
notify each of RCFC and the Trustee whether the Note Purchaser has determined
to make such Advances.  On the date of





                                      -3-
<PAGE>   7
each Borrowing and subject to the other conditions set forth herein and in the
Series 1998-1 Supplement, the Note Purchaser shall make available to RCFC the
amount of such Advance by wire transfer in U.S. dollars of such amount in same
day funds to the Series 1998-1 Collection Account no later than 5:00 p.m. (New
York City time) on the proposed date of such Borrowing.

                 SECTION 2.03  Decreases.  (a)  Mandatory Decreases.  Whenever
the Enhancement Amount is less than the Minimum Enhancement Amount or an Asset
Amount Deficiency exists, then, on the Payment Date immediately following
discovery of such deficiency, RCFC shall decrease the Series 1998-1 Invested
Amount of the Series 1998-1 Notes as required under Section 4A.3(a) of the
Series 1998-1 Supplement.

                 (b)  Voluntary Decreases.  Upon at least three (3) Business
Days' prior irrevocable notice to the Note Purchaser in writing, RCFC may
voluntarily reduce the Series 1998-1 Invested Amount of the Series 1998-1 Notes
in accordance with the procedures set forth in Section 4A.3(b) of the Series
1998-1 Supplement.

                 SECTION 2.04  CP Stop Issuance Events.  Notwithstanding
anything to the contrary herein, upon the occurrence and during the
continuation of a CP Stop Issuance Event, the Note Purchaser shall not make any
Advances hereunder and shall not issue Commercial Paper Notes in order to fund
or maintain its investments in the Series 1998-1 Notes.  Each of RCFC and the
Master Servicer agrees to give the Collateral Agent and the Note Purchaser
prompt written notice of any CP Stop Issuance Event.  It is expressly
understood that the occurrence of a CP Stop Issuance Event once no longer
continuing shall not relieve the Note Purchaser of its obligation to make
future Advances hereunder.


                                  ARTICLE III
                               INTEREST AND FEES

                 SECTION 3.01  Interest.    Each Advance funded or maintained by
the Note Purchaser during the relevant Fixed Period (a) through the issuance of
Commercial Paper Notes shall bear interest at the CP Rate for such Fixed Period
as determined by DTFC pursuant to the Liquidity Agreement and (b) through means
other than the issuance of Commercial Paper Notes shall bear interest at (i)
the Base Rate as determined by the Liquidity Agent pursuant to the Liquidity
Agreement or (ii) if the required notice has been given, the Eurodollar Rate
for such Fixed Period as determined by the Liquidity Agent pursuant to the
Liquidity Agreement, except as otherwise provided in the definition of Fixed
Period; provided, however, that in each case, if a Series 1998-1 Rapid
Amortization Period has commenced and is continuing, then interest on the
Advances shall bear interest at a per annum rate equal to the Base Rate plus
0.50%.

                 (a)  Interest shall be due and payable on each Payment Date in
accordance with the provisions set forth in Section 4.9 of the Series 1998-1
Supplement.

                 (b)  All computations of interest at the CP Rate and
Eurodollar Rate shall be made on the basis of a year of 360 days and the actual
number of days elapsed and all computations of interest at the Base Rate shall
be made on the basis of a 365 (or 366, as applicable) day year and actual
number of days elapsed.  Whenever any payment of interest or principal in
respect of any Advance shall be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day and such extension of
time shall be included in the computation of the amount of interest owed.

                 SECTION 3.02  [Reserved].

                 SECTION 3.03  Certain Eurocurrency Rate and Other Provisions
under the Liquidity Agreement and Credit Agreement.  If any Program Support
Provider is unable to provide Eurodollar loans, or experiences increased costs,
funding losses, increased capital costs, taxes, or other expenses  pursuant to
Sections 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6 of the Liquidity Agreement or
Sections 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6 of the Credit Agreement, such amounts
shall be payable by RCFC to DTFC and by DTFC directly to such Program Support
Provider. DTFC agrees that any notices it receives from any Program Support

                 (i)      the negotiation, preparation, execution, delivery and
         administration of this Agreement and of each other Related Document,
         including schedules and exhibits, and any amendments, waivers,
         consents, supplements or other modifications to this Agreement or any
         other Related Document as may from time to time hereafter be proposed,
         whether or not the transactions contemplated hereby or thereby are
         consummated, and

                 (ii)     the consummation and performance of the transactions
         contemplated by this Agreement, the CP Program Documents and the other
         Related Documents, including, without limitation, fees, costs,
         expenses and indemnities for the Collateral Agent, Liquidity Agent,
         each Liquidity Lender, each Dealer, and the Depositary.

RCFC further agrees to pay, and to save the Note Purchaser harmless from all
liability for, (i) any breach by RCFC of its obligations under this Agreement
(ii) all reasonable costs incurred by the Note Purchaser in enforcing this
Agreement and (iii) any stamp, documentary or other taxes which may be payable
in connection with the execution or delivery of this Agreement, any Borrowing

all reasonable out-of-pocket expenses incurred by the Note Purchaser in
connection with (x) the negotiation of any restructuring or "work-out", whether
or not consummated, of the Related Documents and (y) the enforcement of the
Related Documents.

                 (b)  Indemnification.  In consideration of the execution and
delivery of this Agreement by the Note Purchaser, RCFC hereby indemnifies and
holds the Note Purchaser, the Collateral Agent, and each of their respective
officers, directors, employees and agents (collectively, the "Indemnified
Parties") harmless from and against any and all actions, causes of action,
suits, losses, costs, liabilities and damages, and reasonable expenses incurred
in connection therewith (irrespective of whether any such Indemnified Party is
a party to the action for which indemnification hereunder is sought and
including, without limitation, any liability in connection with the offering
and sale of the Series 1998-1 Notes), including reasonable attorneys' fees and
disbursements (collectively, the "Indemnified Liabilities"), incurred by the
Indemnified Parties or any of them (whether in prosecuting or defending against
such actions, suits or claims) as a result of, or arising out of, or relating
to

                 (i)      any transaction financed or to be financed in whole
         or in part, directly or indirectly, with the proceeds of any Advance;
         or





                                      -13-
<PAGE>   17
                 (ii)     the entering into and performance of this Agreement
         and any other Related Document by any of the Indemnified Parties,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's
gross negligence or willful misconduct.  If and to the extent that the
foregoing undertaking may be unenforceable for any reason, RCFC hereby agrees
to make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under applicable law.  The
indemnity set forth in this Section 8.05(b) shall in no event include
indemnification for any taxes (which indemnification is provided in Section
3.03).  RCFC shall give notice to the Rating Agencies of any claim for
Indemnified Liabilities made under this Section.

                 (c) Carrying Charges. All expenses payable under this Section
8.05 shall constitute Carrying Charges within the meaning of the Indenture.

                 SECTION 8.06  Characterization as Related Document; Entire
Agreement.  This Agreement shall be deemed to be a Related Document for all
purposes of the Base Indenture and the other Related Documents.  This
Agreement, together with the Base Indenture, the Series 1998-1 Supplement, the
documents delivered pursuant to Section 6.01 and the other Related Documents,
including the exhibits and schedules thereto, contains a final and complete
integration of all prior expressions by the parties hereto with respect to the
subject matter hereof and shall constitute the entire agreement among the
parties hereto with respect to the subject matter hereof, superseding all
previous oral statements and other writings with respect thereto.

                 SECTION 8.07  Notices.  All notices, amendments, waivers,
consents and other communications provided to any party hereto under this
Agreement shall be in writing and addressed, delivered or transmitted to such
party at its address or facsimile number set forth below its signature hereto
or at such other address or facsimile number as may be designated by such party
in a notice to the other parties.  Any notice, if mailed and properly addressed
with postage prepaid or if properly addressed and sent by pre-paid courier
service, shall be deemed given when received; any notice, if transmitted by
facsimile, shall be deemed given when transmitted upon receipt of electronic
confirmation of transmission.

                 SECTION 8.08  Severability of Provisions.  Any covenant,
provision, agreement or term of this Agreement that is prohibited or is held to
be void or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of the prohibition or unenforceability without
invalidating the remaining provisions of this Agreement.

                 SECTION 8.09  Tax Characterization.  Each party to this
Agreement (a) acknowledges that it is the intent of the parties to this
Agreement that, for accounting purposes and for all federal, state and local
income and franchise tax purposes, the Series 1998-1 Notes





                                      -14-
<PAGE>   18
will be treated as evidence of indebtedness issued by RCFC, (b) agrees to treat
the Series 1998-1 Notes for all such purposes as indebtedness and (c) agrees
that the provisions of the Related Documents shall be construed to further
these intentions.

                 SECTION 8.10  No Proceedings; Limited Recourse.  (a)  RCFC.
Each of DTAG, the Collateral Agent (solely in its capacity as such) and the
Note Purchaser (solely in its capacity as such) hereby covenants and agrees
that, prior to the date which is one year and one day after the payment in full
of any Notes issued by RCFC pursuant to the Base Indenture, it will not
institute against, or join with any other Person in instituting against, RCFC,
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings, or other proceedings under any Federal or state bankruptcy or
similar law, all as more particularly set forth in Section 12.16 of the Base
Indenture and subject to any retained rights set forth therein; provided,
however, that nothing in this Section 8.10(a) shall constitute a waiver of any
right to indemnification, reimbursement or other payment from RCFC pursuant to
this Agreement, the Series 1998-1 Supplement or the Base Indenture.  In the
event that DTAG, the Collateral Agent (solely in its capacity as such) or the
Note Purchaser (solely in its capacity as such) takes action in violation of
this Section 8.10(a), RCFC agrees that it shall file an answer with the
bankruptcy court or otherwise properly contest the filing of such a petition by
any such Person against RCFC or the commencement of such action and raise the
defense that such Person has agreed in writing not to take such action and
should be estopped and precluded therefrom and such other defenses, if any, as
its counsel advises that it may assert.  The provisions of this Section 8.10(a)
shall survive the termination of this Agreement and the resignation or removal
of the Collateral Agent.  Nothing contained herein shall preclude participation
by DTAG, the Collateral Agent or the Note Purchaser in assertion or defense of
its claims in any such proceeding involving RCFC.  The obligations of RCFC
under this Agreement are solely the corporate obligations of RCFC.  No recourse
shall be had for the payment of any amount owing in respect of this Agreement,
including the payment or any fee hereunder or any other obligation or claim
arising out of or based upon this Agreement, against any stockholder, employee,
officer, director, affiliate or incorporator of RCFC; provided, however,
nothing in this Section 8.10(a) shall relieve any of the foregoing Persons from
any liability which any such Person may otherwise have for its gross negligence
or willful misconduct.  In addition, each of the parties hereto agree that all
fees, expenses and other costs payable hereunder by RCFC shall be payable only
to the extent set forth in Section 12.17 of the Base Indenture and that all
other amounts owed to them by RCFC shall be payable solely from amounts that
become available for payment pursuant to the Base Indenture and the Series
1998-1 Supplement.

                 (b)  DTFC.  Each of RCFC, the Master Servicer and the
Collateral Agent (solely in its capacity as such), hereby covenants and agrees
that it will not, and the Master Servicer will cause the Lessees not to, prior
to the date which is one year and one day after the payment in full of the
latest maturing Commercial Paper Notes, institute against, or join with any
other Person in instituting against, DTFC, any bankruptcy, reorganization,
arrangement,





                                      -15-
<PAGE>   19
insolvency or liquidation proceedings, or other proceedings under any federal
or state bankruptcy or similar law, subject to any retained rights set forth
therein; provided, however, that nothing in this Section 8.10(b) shall
constitute a waiver of any right to indemnification, reimbursement or other
payment from DTFC pursuant to the Collateral Agreement or other CP Program
Document or other Related Document.  In the event that RCFC, the Master
Servicer, the Collateral Agent (solely in its capacity as such) or any of the
Lessees takes action in violation of this Section 8.10(b), DTFC agrees that it
shall file an answer with the bankruptcy court or otherwise properly contest
the filing of such a petition by any such Person against DTFC or the
commencement of such action and raise the defense that such Person has agreed
in writing not to take such action and should be estopped and precluded
therefrom and such other defenses, if any, as its counsel advises that it may
assert.  The provisions of this Section 8.10(b) shall survive the termination
of this Agreement and the resignation or removal of the Collateral Agent.
Nothing contained herein shall preclude participation by RCFC, the Master
Servicer, the Collateral Agent or any Lessee  in assertion or defense of its
claims in any such proceeding involving DTFC.  The obligations of DTFC under
this Agreement are solely the corporate obligations of DTFC.  No recourse shall
be had for the payment of any amount owing in respect of this Agreement,
including the payment or any fee hereunder or any other obligation or claim
arising out of or based upon this Agreement, against any stockholder, employee,
officer, director, affiliate or incorporator of DTFC; provided, however,
nothing in this Section 8.10(b) shall relieve any of the foregoing Persons from
any liability which any such Person may otherwise have for its gross negligence
or willful misconduct.

                 SECTION 8.11  Confidentiality. Each of the Collateral Agent
and the Note Purchaser agrees that it shall not disclose any Confidential
Information to any Person without the prior written consent of DTFC, the Master
Servicer, RCFC  and the applicable Lessee. Notwithstanding anything herein to
the contrary, the foregoing shall not be construed to prohibit any party hereto
from (i) disclosing any and all information that is or becomes publicly known
through no fault of a Secured Party, (ii) disclosure of any and all information
(which makes reference to RCFC or DTFC or this transaction) obtained by any
Secured Party from sources (other than RCFC or DTFC) that have not notified the
Secured Party or Parties that such information is subject to a confidentiality
obligation with RCFC or DTFC (iii) disclosing any and all information (A) if
required to do so by any applicable statute, law, rule or regulation, (B) to
any government agency or regulatory body having or claiming authority to
regulate or oversee any aspects of a Secured Party's business or that of its
Affiliates, (C) pursuant to any subpoena, civil investigative demand or similar
demand or request of any court, regulatory authority, arbitrator or arbitration
to which any Secured Party or an Affiliate or an officer, director or employee
thereof is a party, (D) in any preliminary or final offering circular,
registration statement or contract or other document pertaining to the
transactions contemplated herein approved in advance by RCFC or DTFC or (E) to
any Affiliate, independent or internal auditor, agent, employee or attorney of
any Secured Party having a need to know the same, provided that the Secured
Party advises such recipient of the





                                      -16-
<PAGE>   20
confidential nature of the information being disclosed or (iv) any other
disclosure authorized by RCFC or DTFC.

         "Confidential Information" means information that DTFC, RCFC, the
Master Servicer or the applicable Lessee furnishes to the Collateral Agent or
the Note Purchaser on a confidential basis, but does not include any such
information that is or becomes generally available to the public other than as
a result of a disclosure by the Collateral Agent or the Note Purchaser or other
Person to which the Collateral Agent or the Note Purchaser delivered such
information or that is or becomes available to the Collateral Agent or the Note
Purchaser from a source other than DTFC, RCFC, the Master Servicer or
applicable Lessee, provided that such source is not (1) known to the Collateral
Agent or the Note Purchaser to be bound by a confidentiality agreement with
DTFC, RCFC, the Master Servicer or the applicable Lessee, as the case may be,
or (2) known to the Collateral Agent or the Note Purchaser to be otherwise
prohibited from transmitting the information by a contractual, legal or
fiduciary obligation.

                 SECTION 8.12  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK,
WITHOUT REGARD TO OTHERWISE APPLICABLE PRINCIPLES OF CONFLICTS OF LAW.

                 SECTION 8.13  Counterparts.  This Agreement may be executed in
any number of counterparts (which may include facsimile) and by the different
parties hereto in separate counterparts, each of which when so executed shall
be deemed to be an original, and all of which together shall constitute one and
the same instrument.

         SECTION 2.1. Issuance of Commercial Paper Notes. On the terms and
subject to the provisions of this Liquidity Agreement and the other CP Program
Documents, DTFC may from time to time on or after the Closing Date and prior to
the Liquidity Commitment Termination Date, issue and sell Commercial Paper
Notes; provided, however, that DTFC shall not issue and sell Commercial Paper
Notes if

                  (a) DTFC and the Depositary have received instructions then in
         effect from the Liquidity Agent (copies of which will also be sent to
         the Dealers), given in accordance with this Section 2.1, not to issue
         or deliver Commercial Paper Notes because (i) the Liquidity Commitment
         Termination Date shall have occurred, or (ii) the Commercial Paper
         Account or any funds on deposit in, or otherwise to the credit of, the
         Commercial Paper Account shall be subject to any stay, writ, judgment,
         warrant of attachment, execution or similar process; provided, however,

         or similar process is removed or dismissed, DTFC may recommence the
         issuance and sale of Commercial Paper Notes,

                  (b) the issuance of Commercial Paper Notes is prohibited by

                  (c) after giving effect to such issuance and the use of
         proceeds thereof, Aggregate Outstandings would exceed the CP Borrowing
         Base,

                  (d) after giving effect to such issuance and the use of
         proceeds thereof, the weighted average interest rate of the Outstanding
         Commercial Paper Notes, Liquidity Advances and LOC Liquidity
         Disbursements would be in excess of 10.00% per annum, unless (i) DTFC
         and the Liquidity Agent shall have given their written consent to a
         weighted average interest rate in excess of 10.00% per annum, (ii) the
         Enhancement Amount shall be increased if required by the Rating
         Agencies in connection therewith and (iii) the Rating Agencies shall
         have confirmed that such weighted average interest rate will not result
         in the downgrading or withdrawal of the then current ratings of the
         Commercial Paper Notes; provided, however, that if the ratings of the
         Commercial Paper Notes by S&P, Moody's, and DCR will be less than A-1,
         P-1, and D-1 respectively, after giving effect to such weighted average
         interest rate in excess of 10.00% per annum, such Commercial Paper
         Notes will not be issued unless the Majority Banks shall have given
         their written consent thereto, or

                  (e) DTFC and the Depositary shall have received instructions
         then in effect from the Liquidity Agent not to issue or deliver
         Commercial Paper Notes because any of the conditions set forth in
         clauses (b) through (d) of this Section 2.1 shall be true.

The Liquidity Agent shall have no obligation to deliver any instructions set
forth in clause (a) or clause (e) of this Section 2.1 except upon the
instructions of the Majority Banks and any delivery by the Liquidity Agent of
any such instructions shall be subject to the provisions of Section 10.3 and the
rights of the Liquidity Agent hereunder and shall not relieve DTFC, the
Collateral Agent or the Depositary of any of their respective obligations under
any CP Program Document or with respect to the issuance of Commercial Paper
Notes. Any instructions from the Liquidity Agent to DTFC and the Depositary in
accordance with clause (a) or clause (e) of this Section 2.1 shall specify the
reason(s) to cease issuing and delivering Commercial Paper Notes. Without prior
instruction as set forth above, the Liquidity Agent agrees that it shall only
instruct DTFC and the Depositary not to issue and sell Commercial Paper Notes if
there shall have occurred an event described in subclause (i) of clause (a) of
this Section 2.1. Concurrently with the giving of any such instructions to DTFC
and the Depositary, the Liquidity Agent shall give notice thereof to the
Liquidity Lenders, the Collateral Agent, the Dealers, and the Rating Agencies,
but failure to do so shall not impair the effect of such instructions and the
giving of such notice shall be subject to Section 10.3.

         SECTION 2.2. Conditions to the Issuance of Commercial Paper Notes. The
right of DTFC to issue Commercial Paper Notes (whether such Commercial Paper
Notes are to be issued to refinance Commercial Paper Notes maturing on the day
such Commercial Paper Notes are to be issued or to increase the Aggregate Face
Amount over that of the preceding day) is subject to the satisfaction of the
following conditions:

issuance of any Commercial Paper Note and after giving effect thereto, the
representations and warranties of DTFC set forth in Article VII hereof, or in
any other CP Program Document to which DTFC is a party, shall be true and
correct (in all material respects to the extent any such representations and
warranties do not incorporate a materiality limitation in their terms) with the
same effect as if then made (unless stated to relate solely to an earlier date,

not incorporate a materiality limitation in their terms) as of such earlier
date.

Aggregate Face Amount over that of the day preceding the day of such issuance,
no other Potential Liquidity Agreement Amortization Event) shall have occurred

         (b) Such issuance of Commercial Paper Notes shall not be prohibited by
Section 9.4.

         SECTION 2.2.3. Available Liquidity Commitment. At the time of the

the principal of Liquidity Advances.

         SECTION 2.2.4. No CP Borrowing Base Deficiency. With respect to the
issuance of any Commercial Paper Note, a CP Borrowing Base Deficiency shall not
exist and the issuance of such Commercial Paper Note, after giving effect to the
repayment of any Commercial Paper Notes, Liquidity Advances and LOC Liquidity
Disbursements made with the proceeds thereof, would not result in a CP Borrowing
Base Deficiency.

         SECTION 2.2.5. CP Borrowing Base Certificate. The Liquidity Agent shall
have received an Officer's Certificate, dated the date of such issuance, duly
executed and delivered by an Authorized Officer of DTFC, certifying the amount

pursuant to Section 2.01 or 5.02 of the Collateral Agreement, as applicable,
then

         SECTION 3.1.1. Refunding Advance Commitment. Subject to and in
accordance with the terms and conditions hereof (including, without limitation,
the terms and conditions set forth in Section 6.3), each Liquidity Lender
severally and not jointly agrees to make, from time to time, on or before such
Liquidity Lender's Liquidity Commitment Termination Date, advances for the
purposes set forth in Section 3.1.3 (relative to such Liquidity Lender
(including its Commitment Termination Date Liquidity Advance), its "Refunding
Advances") to DTFC equal to (a) in the case of Refunding Advances (other than
any Commitment Termination Date Liquidity Advance), such Liquidity Lender's
Percentage of the aggregate amount of the Borrowing of Refunding Advances
requested by DTFC or the Collateral Agent, as attorney-in-fact for DTFC, to be
made on such day, and (b) in the case of Commitment Termination Date Liquidity
Advances, such Liquidity Lender's Overall Percentage of the Aggregate Face
Amount on the date of such Commitment Termination Date Liquidity Advance. On the
terms and subject to the conditions hereof, DTFC may from time to time borrow,

         SECTION 3.1.2. Swing Line Commitment. Subject to and in accordance with
the terms and conditions hereof (including, without limitation, the terms and
conditions set forth in Section 6.3), the Swing Line Lender agrees to make, from

                                       -7-



<PAGE>   16



proceeds of each Commitment Termination Date Liquidity Advance shall be
deposited by DTFC into the Termination Advance Account, in each case, for the
repayment of maturing Commercial Paper Notes or to repay matured Liquidity
Advances. DTFC shall not use the proceeds of any Liquidity Advance for any other
purpose.

         SECTION 3.2. Liquidity Lenders Not Required to Make Certain Liquidity
Advances.

         SECTION 3.2.1. Liquidity Advances. No Liquidity Lender shall be
required to make a Liquidity Advance to the extent that after giving effect to
such Liquidity Advance (i) the aggregate principal amount of all Liquidity
Advances (including any Swing Line Advances) Outstanding would exceed the
Aggregate Liquidity Commitment or (ii) the aggregate principal amount of such
Liquidity Lender's Liquidity Advances (including, in the case of the Swing Line
Lender, any Swing Line Advances) Outstanding would exceed such Liquidity
Lender's Liquidity Commitment.

         SECTION 3.2.2. Failure To Fund. The provisions of this Section 3.2.2
shall only be operative at any time when the number of Liquidity Lenders whose
respective Liquidity Commitments have not expired or been terminated and the
Series 1998-1 Letter of Credit Provider shall exceed one (1) in the aggregate.
Subject to Section 3.2.1, in the event that one or more Liquidity Lenders fails
to fund its or their Percentage of the Liquidity Advances to be provided by the
Liquidity Lenders by 3:00 p.m., New York City time, on any Business Day (other
than a Commitment Termination Date Liquidity Advance or a Liquidity Advance the
proceeds of which are to be used to repay maturing Liquidity Advances), the
Liquidity Agent shall notify each of the other Liquidity Lenders not later than
4:00 p.m., New York City time, on such Business Day and each of the other
Liquidity Lenders shall, before 5:00 p.m., New York City time, on such Business
Day, make available to the Liquidity Agent at the Liquidity Agent's address
specified for such purpose, in immediately available funds, a Liquidity Advance
in a principal amount equal to such unfunded amount multiplied by a fraction,
the numerator of which is the Liquidity Commitment of such Liquidity Lender and
the denominator of which is the Aggregate Liquidity Commitment (less the
Liquidity Commitments of the defaulting Liquidity Lenders). After the Liquidity
Agent's receipt of such funds and upon fulfillment of the applicable conditions
set forth in Article VI, the Liquidity Agent will make such funds available to
DTFC by 5:30 p.m., New York City time. Any Liquidity Advance made pursuant to
this Section 3.2.2 shall be a Base Rate Advance subject to conversion in
accordance with the provisions of Section 3.8 hereof.

         SECTION 3.3. Termination and Reduction of the Liquidity Commitments.
(a) DTFC may, upon at least three Business Days' prior written notice to the
Liquidity Agent bearing the signatures of two (2) Authorized Officers of DTFC
(who shall give prompt written notice thereof to each Liquidity Lender, the
Dealers and the Depositary), irrevocably terminate or reduce in part the
Aggregate Liquidity Commitment; provided, however, that the Aggregate Liquidity
Commitment shall not be reduced on any day in an amount such that the Aggregate


                                       -8-



<PAGE>   17



Liquidity Commitment would be less than the sum of (i)(x) the Aggregate
Outstanding CP on such day, less (y) the Series 1998-1 Letter of Credit Amount,
plus (ii) the aggregate principal amount of all Liquidity Advances (including
any Swing Line Advances) Outstanding (other than Commitment Termination Date
Liquidity Advances) on such day net of any amounts on deposit on such day in the
Collateral Account set aside for the repayment of the principal of Liquidity
Advances; provided, further, that any partial reduction shall be at least
$5,000,000 with respect to the first reduction and in an integral multiple of
$1,000,000 thereafter. Any such reduction of the Aggregate Liquidity Commitment
shall reduce ratably the Liquidity Commitment of each Liquidity Lender.

         (b) The Liquidity Agent shall give notice to the Dealers as to any
change in the Aggregate Liquidity Commitment promptly after any reduction
thereof.

         (c) No termination or reduction of the Aggregate Liquidity Commitment
by DTFC pursuant to this Section 3.3 shall be effective unless the Liquidity
Agent or DTFC shall have given notice to S&P, Moody's and DCR of such
termination or reduction.

         SECTION 3.4. Increase of the Aggregate Liquidity Commitment. The
Aggregate Liquidity Commitment may be increased from time to time to an amount
greater than the amount of the Aggregate Liquidity Commitment then in effect
through the increase of a Liquidity Lender's Liquidity Commitment or the
addition of one or more Eligible Liquidity Lenders as a party to this Liquidity
Agreement; provided, however, that no such increase shall become effective
unless all of the following conditions shall have been satisfied:

                  (a) DTFC and the Liquidity Agent shall have given their
         written consent thereto;

                  (b) such Liquidity Lender or Eligible Liquidity Lender, as the
         case may be, and DTFC shall have executed and delivered to the
         Liquidity Agent a Liquidity Commitment Agreement;

                  (c) the Enhancement Amount shall be increased to the Minimum
         Enhancement Amount that would be required by the increased Series
         1998-1 Invested Amount resulting from the increase in the Aggregate
         Liquidity Commitment;

                  (d) the conditions to making Advances under Section 2.01 of
         the Note Purchase Agreement shall have been met; and

                  (e) the Rating Agencies confirm in writing that such increase
         in the Aggregate Liquidity Commitment will not result in the
         downgrading below the then current ratings or a withdrawal of the
         ratings of the Commercial Paper Notes.

         SECTION 3.5. Extensions of Scheduled Liquidity Commitment Termination
Date. Each Liquidity Lender's Scheduled Liquidity Commitment Termination Date
may be extended from time to time by a written agreement among DTFC, such
Liquidity Lender and the Liquidity Agent.

         SECTION 3.6. Borrowing Procedures. Borrowings of Refunding Advances,
Commitment Termination Date Liquidity Advances and Swing Line Advances shall be
made in accordance with this Section 3.6.

         SECTION 3.6.1. Refunding Advances. (a) Upon receipt from DTFC of notice
(not later than 12:15 p.m., New York City time) pursuant to Section 5(b) of the
Depositary Agreement that, on any Business Day that any Commercial Paper Notes
mature, the amount required to pay in full all Commercial Paper Notes maturing
on such Business Day will be more than the net amount obtained by the issuance
of Commercial Paper Notes on such day plus the amount available for payment of
such Commercial Paper Notes in the Commercial Paper Account (the amount of such
excess, the "Commercial Paper Deficit"), the Collateral Agent shall, if such
notice contains an instruction from the Depositary to the Collateral Agent to
deliver a Borrowing Request, by delivering a Borrowing Request to the Liquidity
Agent (who will notify the other Liquidity Lenders of such Borrowing Request not
later than 2:00 p.m., New York City time) for a Borrowing consisting of
Refunding Advances, irrevocably request, not later than 12:30 p.m., New York
City time, on the date of a proposed Borrowing, that a Borrowing be made in an
aggregate principal amount equal to the excess, if any, of (A) the Commercial
Paper Deficit over (B) the sum of the aggregate amount, if any, applied or to be
applied on such Business Day to the Commercial Paper Deficit from amounts
available therefor in the Collateral Account and the Termination Advance Account
that are allocated to the payment of maturing Commercial Paper Notes and from
the proceeds of Swing Line Advances being made on such day. On the terms and
subject to the conditions of this Liquidity Agreement, each such Borrowing shall
be initially comprised of Base Rate Advances (subject to conversion in
accordance with the provisions of Section 3.8) and shall be made on the Business
Day specified in such Borrowing Request. For the purposes of this Section 3.6.1,
Commercial Paper Notes maturing on any day which have been paid with proceeds of
an advance made by the Depositary that has not been reimbursed shall nonetheless
be deemed to be unpaid.

         (b) If on any Business Day in a Related Month the weighted average
interest rate of the Outstanding Commercial Paper Notes and Outstanding
Liquidity Advances exceeds 10% per annum, then DTFC shall notify the Liquidity
Agent thereof in writing no later than 11:00 a.m. (New York City time), that
unless the requirements for the continued issuance of Commercial Paper Notes set
forth in Section 2.1(d) shall have been complied with not later than 11:00 a.m.
(New York City time) on the last Business Day before the Payment Date with
respect to such Related Month, the Collateral Agent (provided DTFC shall have
delivered the notice specified above), shall, by delivering a Borrowing Request
to the Liquidity Agent (who will notify the


                                      -10-



<PAGE>   19



other Liquidity Lenders of such Borrowing Request not later than 12:00 noon, New
York City time) for a Borrowing consisting of Refunding Advances, irrevocably
request, not later than 11:30 a.m., New York City time, on such last Business
Day before such Payment Date, that such Borrowing be made in an aggregate
principal amount equal to the lesser of (i) the Aggregate Liquidity Commitment
on such date minus the aggregate principal amount of all Liquidity Advances
(including any Swing Line Advances) Outstanding on such date as determined
immediately prior to such Borrowing Request and (ii) the Aggregate Outstanding
CP on such date.

         SECTION 3.6.2. Swing Line Advances. If on any Business Day DTFC or the
Collateral Agent determines that there exists a Commercial Paper Deficit, the
excess of which Commercial Paper Deficit over the sum of the aggregate amount,
if any, applied or to be applied on such Business Day to the Commercial Paper
Deficit from amounts available therefor in the Collateral Account and the
Termination Advance Account that are allocated to the payment of maturing
Commercial Paper Notes is equal to or less than $5,000,000, DTFC or the
Collateral Agent, as the case may be, shall promptly (and in no case later than
12:00 noon New York City, New York time on the date of such discovery) notify
the Depositary of such Commercial Paper Deficit and DTFC or the Collateral
Agent, as attorney-in-fact for DTFC, may, or the Collateral Agent, upon the
instruction of the Depositary pursuant to Section 5(b) of the Depositary
Agreement, shall by delivering a Borrowing Request to the Liquidity Agent for
forwarding to the Swing Line Lender for a Borrowing consisting of a Swing Line
Advance, irrevocably request, not later than 12:30 p.m., New York City time, on
the date of a proposed Borrowing, that a Borrowing be made in an aggregate
principal amount equal to the least of

                  (a) $5,000,000 minus the aggregate principal amount of all
         Swing Line Advances then Outstanding;

                  (b) the excess, if any, of the Swing Line Lender's Liquidity
         Commitment as a Liquidity Lender over the aggregate principal amount of
         all of its Liquidity Advances Outstanding on the date of such proposed
         Borrowing (without giving effect to such proposed Borrowing); and

                  (c) the excess of the Commercial Paper Deficit over the sum of
         the aggregate amount, if any, applied or to be applied on such Business
         Day to the Commercial Paper Deficit from amounts available therefor in
         the Collateral Account and the Termination Advance Account that are
         allocated to the payment of maturing Commercial Paper Notes.

On the terms and subject to the conditions of this Liquidity Agreement, each
such Borrowing shall be a Base Rate Advance (subject to conversion in accordance
with the provisions of Section 3.8), and shall be made on the Business Day
specified in such Borrowing Request. For the purposes of this Section 3.6.2,
Commercial Paper Notes maturing on any day which


                                      -11-



<PAGE>   20



have been paid with proceeds of an advance made by the Depositary that has not
been reimbursed shall nonetheless be deemed to be unpaid. If, after giving
effect to any Swing Line Advance requested pursuant to this Section 3.6.2, (a)
the aggregate principal amount of Swing Line Advances would be greater than
$5,000,000, or (b) the aggregate principal amount of Swing Line Advances is less
than or equal to $5,000,000 and such Swing Line Advances are not repaid within
five Business Days or (c) the aggregate principal amount of all Liquidity
Advances Outstanding made by the Swing Line Lender would exceed its Liquidity
Commitment, then in any such case, subject to Section 3.2.1, each Liquidity
Lender shall immediately and unconditionally, upon written notice thereof by the
Swing Line Lender, make a Refunding Advance to DTFC in an amount equal to such
Liquidity Lender's Percentage of the aggregate principal amount of the Swing
Line Advances Outstanding, the proceeds of which Refunding Advance will be
applied to the repayment of Swing Line Advances made by the Swing Line Lender.
Notwithstanding Section 6.3, the obligation of the Liquidity Lenders to make
Liquidity Advances under this Section 3.6.2 shall be unconditional. The Swing
Line Advances and Liquidity Advances made pursuant to this Section 3.6.2 shall
be comprised of Base Rate Advances, subject to conversion in accordance with the
provisions of Section 3.8 hereof.

         SECTION 3.6.3. Commitment Termination Date Liquidity Advances. DTFC may
request each Liquidity Lender, on the Scheduled Liquidity Commitment Termination
Date with respect to such Liquidity Lender's Liquidity Commitment, to make a
Refunding Advance to DTFC on the terms and subject to the conditions of this
Liquidity Agreement. Any such Commitment Termination Date Liquidity Advance
shall not exceed such Liquidity Lender's Overall Percentage of the Aggregate
Face Amount on the date of such Commitment Termination Date Liquidity Advance
and the aggregate amount of any previously made Liquidity Advances of such
Liquidity Lender that are outstanding on such date shall be converted into, and
for all purposes of this Liquidity Agreement shall be treated as, a Commitment
Termination Date Liquidity Advance.

         SECTION 3.6.4. Nature of Funding Obligations. The obligations of the
Liquidity Lenders hereunder are several and not joint. All Liquidity Advances
(other than Swing Line Advances and Commitment Termination Date Liquidity
Advances) under this Liquidity Agreement shall be made by the Liquidity Lenders
simultaneously and proportionately to their respective Percentages, it being
understood that, subject to Section 3.2.2, no Liquidity Lender shall be
responsible for any failure by any other Liquidity Lender to perform its
obligation to make a Liquidity Advance hereunder and that the Liquidity
Commitment of any Liquidity Lender shall not be increased or decreased as a
result of the failure by any other Liquidity Lender to perform its obligation to
make a Liquidity Advance. The failure of any Liquidity Lender to make available
to the Liquidity Agent its ratable share of any Borrowing shall not relieve any
other Liquidity Lender of its obligation hereunder to make available to the
Liquidity Agent such other Liquidity Lender's pro rata share of such Borrowing
on the date such funds are to be made available pursuant to the terms of this
Liquidity Agreement.


                                      -12-

Notwithstanding the foregoing, each Liquidity Lender shall continue to be
obligated to make Liquidity Advances upon a default by a Liquidity Lender as
required by Section 3.2.2.

         SECTION 3.6.5. Failure to Fund by Liquidity Lender. Unless the
Liquidity Agent shall have been notified by any Liquidity Lender prior to 2:30
p.m., New York City time, on the date of any Borrowing in respect of any
Liquidity Advances that such Liquidity Lender does not intend to make available
to the Liquidity Agent such Liquidity Lender's Liquidity Advances on such date
of Borrowing, the Liquidity Agent may assume that such Liquidity Lender has made
such amount available to the Liquidity Agent on such date of Borrowing and the
Liquidity Agent in its sole discretion may, but shall not be obligated to, make
available to DTFC a corresponding amount on such date of Borrowing. If such
corresponding amount is not in fact made available to the Liquidity Agent by
such Liquidity Lender on or prior to a date of Borrowing, such Liquidity Lender
agrees to pay to the Liquidity Agent forthwith on demand such corresponding
amount together with interest thereon, and DTFC agrees to repay to the Liquidity
Agent (to the extent not paid by the defaulting Liquidity Lender) forthwith on
the Business Day immediately following the date of demand therefor such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to DTFC until the date such amount is paid or
repaid to the Liquidity Agent, at (a) in the case of such Liquidity Lender, the
Federal Funds Rate for the first Business Day and thereafter at the Base Rate,
and (b) in the case of DTFC, the interest rate that would be applicable at the
time to a Borrowing of Base Rate Advances made on such date of Borrowing. If
such Liquidity Lender shall pay to the Liquidity Agent such corresponding
amount, such amount so paid shall constitute such Liquidity Lender's Liquidity
Advance, and if both such Liquidity Lender and DTFC shall have paid and repaid,
respectively, such corresponding amount, the Liquidity Agent shall promptly pay
over to DTFC such corresponding amount in same day funds, but DTFC shall remain
obligated for all interest thereon. To the extent any such amount due to the
Liquidity Agent under this Section 3.6.5 has not been paid in full, the
Liquidity Agent may make a demand on the Collateral Agent to pay such amount in
accordance with Sections 2.01 and 5.02(b) of the Collateral Agreement.

         SECTION 3.7. Disbursement of Funds. (a) Upon receipt of each Borrowing
Request for Refunding Advances, the Liquidity Agent shall give to each Liquidity
Lender prompt notice thereof and of such Liquidity Lender's share of the
Borrowing requested thereby no later than 2:00 p.m., New York City time, on the
date of receipt. On or before 3:00 p.m., New York City time, on the date of the
proposed Borrowing, each Liquidity Lender shall deposit with the Liquidity Agent
same day funds in an amount equal to (i) such Liquidity Lender's Percentage of
the requested Borrowing (except in the case of a Commitment Termination Date
Liquidity Advance) or (ii) in the case of a Commitment Termination Date
Liquidity Advance, such Liquidity Lender's Overall Percentage of the Aggregate
Face Amount on the date of such Commitment Termination Date Liquidity Advance.
Such deposit will be made to a segregated trust account (Account No. 931454-31)
established by the Liquidity


                                      -13-



<PAGE>   22



Agent or such other account which the Liquidity Agent shall specify from time to
time by notice to the Liquidity Lenders.

         (b) Upon receipt of a Borrowing Request for a Swing Line Advance, the
Liquidity Agent shall give the Swing Line Lender prompt notice thereof and of
the amount of the Borrowing requested thereby. On or before 2:00 p.m., New York
City time, on the date of the proposed Borrowing, the Swing Line Lender shall
deposit with the Liquidity Agent same day funds in an amount equal to the
requested Borrowing. Such deposit shall be made to an account which the
Liquidity Agent shall specify from time to time by notice to the Swing Line
Lender.

         (c) Unless the Liquidity Agent determines that any condition specified
in Section 6.3, in the case of Refunding Advances or Swing Line Advances, has
not been satisfied, the Liquidity Agent will remit the aggregate of the amounts
of (i) Refunding Advances or Swing Line Advances so made available by the
Liquidity Lenders (or, in the case of any Swing Line Advance, the Swing Line
Lender) to the Commercial Paper Account and (ii) Commitment Termination Date
Liquidity Advances so made available by the Liquidity Lenders to the Termination
Advance Account.

         SECTION 3.8. Continuation and Conversion Elections. By delivering a
Continuation/ Conversion Notice to the Liquidity Agent (which will give prompt
notice to the Liquidity Lenders) on or before 11:15 a.m., New York City time, on
a Business Day, DTFC may from time to time irrevocably elect that all or any
portion in an aggregate minimum amount of $5,000,000 and an integral multiple of
$1,000,000 of any Liquidity Advances be

                  (a) in the case of Base Rate Advances, on not less than three
         nor more than five Business Days' prior notice, converted into
         Eurodollar Advances; or

                  (b) in the case of Eurodollar Advances, on prior notice given
         not less than three nor more than five Business Days prior to the end
         of the related Interest Period, continued as Eurodollar Advances.

In the absence of delivery of a Continuation/Conversion Notice at least three
Business Days prior to the last day of the related Interest Period, in the case
of any Eurodollar Advance, such Eurodollar Advance shall, on such last day,
automatically convert to a Base Rate Advance. In the absence of delivery of a
Continuation/Conversion Notice at least three Business Days prior to the last
day of the related Interest Period, in the case of any Base Rate Advance, such
Base Rate Advance shall automatically continue as a Base Rate Advance. No
portion of the principal amount of any Liquidity Advances Outstanding may be
continued as, or be converted into, Eurodollar Advances when any Liquidity
Agreement Amortization Event or Potential Liquidity Agreement Amortization Event
has occurred and is continuing.

<PAGE>   23



         SECTION 3.9. Eurodollar Funding. (a) Each Liquidity Lender may, if it
so elects, fulfill its obligation to make, continue or convert Eurodollar
Advances hereunder by causing one of its foreign branches or Affiliates (or an
international banking facility created by such Liquidity Lender) to make or
maintain such Eurodollar Advance; provided, however, that such Eurodollar
Advance shall nonetheless be deemed to have been made and to be held by such
Liquidity Lender, and the obligation of DTFC to repay such Eurodollar Advance
shall nevertheless be to such Liquidity Lender for the account of such foreign
branch, Affiliate or international banking facility.

         (b) DTFC shall not be permitted to request, and the Liquidity Lenders
shall not be required to maintain, any number of Interest Periods with respect
to Eurodollar Advances in effect at any time hereunder in excess of 20.

         SECTION 3.10. Liquidity Advance Notes. Each Liquidity Lender's
Liquidity Advances (including its Refunding Advances and Commitment Termination
Date Liquidity Advance and, in the case of the Swing Line Lender, any Swing Line
Advances) under its Liquidity Commitment shall be evidenced by a Liquidity
Advance Note, duly executed on behalf of DTFC, and payable to the order of such
Liquidity Lender in a maximum principal amount equal in each case to such
Liquidity Lender's original Liquidity Commitment (which Liquidity Advance Note
shall, unless requested by such Liquidity Lender, be in substantially the form
of Exhibit A to this Liquidity Agreement and shall be held by the Liquidity
Agent on behalf of the Liquidity Lenders). DTFC hereby irrevocably authorizes
each Liquidity Lender to make (or cause to be made) appropriate notations on the
grid attached to such Liquidity Lender's Liquidity Advance Note (or on any
continuation of such grid), which notations, if made, shall evidence, inter
alia, the date of, the outstanding principal of, and the interest rate and
Interest Period applicable to, the Liquidity Advances evidenced thereby. Such
notations shall be conclusive and binding on DTFC absent manifest error;
provided, however, that the failure of any Liquidity Lender to make any such
notation or any error in any such notation shall not limit or otherwise affect
any Obligations of DTFC.


                                   ARTICLE IV

                REPAYMENTS, PREPAYMENTS, INTEREST AND FEES, ETC.

         SECTION 4.1. Repayments and Prepayments. DTFC shall repay in full the
unpaid principal amount of each Liquidity Advance on the earlier to occur of (i)
the Scheduled Maturity Date and (ii) the date all Obligations are declared or
otherwise become due and payable under Section 9.2. Prior thereto, DTFC shall
make repayments and prepayments in accordance with this Section 4.1.


                                      -15-



<PAGE>   24



         SECTION 4.1.1. Voluntary Prepayments. From time to time on any Business
Day, DTFC may make a voluntary prepayment, in whole or in part, of the
outstanding principal amount of any Liquidity Advance; provided, however, that

                  (a) DTFC shall, in the case of the voluntary prepayment of any
         Eurodollar Advance, give the Liquidity Agent at least three but no more
         than five Business Days' prior written notice (which notice shall be
         irrevocable) of its intent to prepay such Eurodollar Advance and DTFC
         shall specify in such prior written notice the amount of such
         prepayment;

                  (b) all such voluntary prepayments which are partial
         prepayments shall be in a minimum aggregate principal amount equal to
         $1,000,000 and in an integral multiple of $100,000;

                  (c) all such voluntary prepayments shall be applied, unless
         otherwise specified by DTFC, first, pro rata among Base Rate Advances
         for the repayment thereof and then, pro rata among Eurodollar Advances
         having the same Interest Period in the inverse order of their
         maturities, for the repayment thereof; and

                  (d) no such voluntary prepayment of any Eurodollar Advance may
         be made on any day other than the last day of the Interest Period for
         such Eurodollar Advance unless, as required by Section 5.4, breakage
         fees are paid in connection with such prepayment.

         SECTION 4.1.2. Mandatory Prepayments. (a) Concurrently with any partial
reduction or termination of the Aggregate Liquidity Commitment pursuant to
Section 3.3, all funds available on such day in the Collateral Account for the
payment of Liquidity Advances, as provided in Section 2.01 or 5.02, as
applicable, of the Collateral Agreement, shall be applied to repay as much of
the Liquidity Advances (and interest accrued thereon) as shall be necessary so
that the sum of the aggregate principal amount of Liquidity Advances Outstanding
(other than Commitment Termination Date Liquidity Advances) plus the Aggregate
Face Amount will not exceed the Aggregate Liquidity Commitment plus the Series
1998-1 Letter of Credit after giving effect to such termination or reduction
and, to the extent such funds are not sufficient to pay such excess (and
interest accrued thereon), all funds subsequently deposited in the Collateral
Account and allocated to the payment of Liquidity Advances in accordance with
the priorities set forth in Section 2.01 or 5.02, as applicable, of the
Collateral Agreement shall be applied to pay such excess (and interest accrued
thereon) until so paid.

         (b) If, on any Business Day, a Borrowing Base Deficiency or CP
Borrowing Base Deficiency, as applicable, exists, all funds available for the
payment of Commercial Paper Notes, Liquidity Advances or LOC Liquidity
Disbursements on such day in the Collateral Account, as provided in Section 2.01
or 5.02, as applicable, of the Collateral Agreement, shall


                                      -16-



<PAGE>   25



be (i) first, deposited in the Commercial Paper Account for application to the
payment of maturing Commercial Paper Notes (and, in the case of deposits made
pursuant to Section 2.01 of the Collateral Agreement, unmatured Commercial Paper
Notes) and (ii) second, applied to repay Liquidity Advances and LOC Liquidity
Disbursements (and interest accrued thereon) pro rata in accordance with their
outstanding principal amount, in each case, as shall be necessary so that after
giving effect to such application there shall be no Borrowing Base Deficiency or
CP Borrowing Base Deficiency, as applicable, and, to the extent such funds or
other amounts are not sufficient therefor, all funds subsequently deposited in
the Collateral Account and allocated to the payment of Liquidity Advances and
LOC Liquidity Disbursements in accordance with the priorities set forth in
Section 2.01 or 5.02, as applicable, of the Collateral Agreement shall be
applied or set aside for the pro rata application thereof to the payment of
Liquidity Advances Outstanding and LOC Liquidity Disbursements Outstanding until
there shall be no Borrowing Base Deficiency or CP Borrowing Base Deficiency, as
applicable.

         (c) Each mandatory payment required by clause (a) (in the case of a
reduction or termination pursuant to Section 3.3) or clause (b) above shall, for
purposes of Section 9.1.1 and all other provisions of this Liquidity Agreement,
be due and payable in full on the Business Day on which such reduction or
termination or such Borrowing Base Deficiency or CP Borrowing Base Deficiency
exists, whether or not sufficient funds are then available to make such payment.

         SECTION 4.2. Interest Provisions. Interest on the principal amount of
Liquidity Advances Outstanding shall accrue and be payable in accordance with
this Section 4.2.

         SECTION 4.2.1. Rates. (a) Pursuant to an appropriately delivered
Borrowing Request or Continuation/Conversion Notice, DTFC may elect that
Liquidity Advances comprising a Borrowing accrue interest at a rate per annum:

                  (i) on that portion maintained from time to time as a Base
         Rate Advance, equal to the Base Rate from time to time in effect; or

                  (ii) on that portion maintained as a Eurodollar Advance,
         during each Interest Period applicable thereto, equal to the Eurodollar
         Rate (Reserve Adjusted) for such Interest Period.

         (b) If any Liquidity Lender shall determine in good faith that reserves
under Regulation D of the Board of Governors of the Federal Reserve System
("Regulation D") are required to be maintained by it in respect of, or that a
portion of its costs of maintaining reserves under Regulation D is properly
attributable to, one or more of its Eurodollar Advances, DTFC shall pay to such
Liquidity Lender additional interest on the unpaid principal amount of each such
Eurodollar Advance from the date such reserves were required to be maintained
until such principal amount is paid in full or converted into a Base Rate
Advance,


                                      -17-



<PAGE>   26



at an interest rate per annum equal at all times to the remainder obtained by
subtracting (i) the Eurodollar Rate for the Interest Period for such Eurodollar
Advance from (ii) the rate obtained by dividing such Eurodollar Rate by an
amount equal to one minus the Eurodollar Reserve Percentage (expressed as a
decimal) of such Liquidity Lender for such Eurodollar Interest Period. Any
Liquidity Lender claiming any additional interest payable pursuant to this
clause (b) shall provide a written certificate to the Liquidity Agent, DTFC and
the Rating Agencies setting forth the amount of such additional interest and
reasonable detail as to the calculation thereof. DTFC shall pay such Liquidity
Lender the amount shown as due on any such certificate within 30 days following
the date on which such certificate was delivered to DTFC.

         SECTION 4.2.2. Post Default Rates. Without giving effect to Section
5.10 hereof, after the date on which any amount of any Liquidity Advance is due
and payable (whether on the last day of an Interest Period, on the Scheduled
Maturity Date, when a mandatory prepayment initially becomes due or upon
acceleration or otherwise), or after any other monetary Obligation of DTFC shall
have become due and payable, DTFC shall pay, but only to the extent permitted by
law, interest (after as well as before judgment) on the principal amount of
Liquidity Advances then Outstanding (whether or not the same shall then be due
and payable) and each other monetary Obligation hereunder (but only if the same
shall then be due and payable in accordance with the terms of this Liquidity
Agreement) at a rate per annum equal to a margin of 2% per annum plus (i) in the
case of any Liquidity Advances then Outstanding and in respect of which Interest
Periods remain in effect, the respective interest rates then applicable to such
Liquidity Advances, and (ii) in all other cases, a rate per annum equal to the
rate per annum that would then be in effect with respect to a Base Rate Advance.

         SECTION 4.3. Payments of Interest. Accrued interest in respect of each
Liquidity Advance shall be payable in arrears (whether by acceleration, demand
or otherwise) on each payment date set forth below:

                  (a) with respect to any Base Rate Advance, on the last
         Business Day of each calendar quarter, beginning with the first such
         date to occur after such Base Rate Advance is made;

                  (b) with respect to any Eurodollar Advance, on the last day of
         each applicable Interest Period (and, if such Interest Period shall
         exceed three months, on the three-month anniversary of the commencement
         of such Interest Period);

                  (c) in the case of any payment or prepayment, in whole or in
         part, of principal outstanding on any Liquidity Advance, on the amount
         and on the date of such payment or prepayment;


                                      -18-



<PAGE>   27



                  (d) with respect to any Base Rate Advance converted into a
         Eurodollar Advance on a day when interest would not otherwise have been
         payable pursuant to clause (a), on the date of such conversion; and

                  (e) on that portion of any Liquidity Advance which is
         accelerated pursuant to Section 9.2, immediately upon such
         acceleration.

Interest accrued on Liquidity Advances or other monetary Obligations arising
under this Liquidity Agreement or any other CP Program Document after the date
such amount is due and payable shall be payable upon demand.

         SECTION 4.4. (a) Computation Basis. Interest accruing based on the Base
Rate shall be computed on the basis of the actual number of days elapsed and a
365 (or, if applicable, 366) day year. Interest accruing based on the Eurodollar
Rate (Reserve Adjusted) shall be computed on the basis of the actual number of
days elapsed and a 360 day year.

         (b) Determination of Rates. The Liquidity Agent shall notify the
Trustee, DTAG, in its capacity as Master Servicer under the Master Lease, and
DTFC, in writing on or prior to each Determination Date regarding the Series
1998-1 Note Rate, Base Rate, CP Rate and Eurodollar Rate for the related
Interest Period.

         SECTION 4.5. Fees. (a) Commitment Fee. DTFC agrees to pay to the
Liquidity Agent for the account of each Liquidity Lender an ongoing commitment
fee (the "Commitment Fee") equal to 0.1875% per annum of the average daily
unused portion of each such Liquidity Lender's Liquidity Commitment, such fee to
accrue from the Closing Date until the Liquidity Commitment Termination Date.
The Commitment Fee shall be computed based on the actual number of days elapsed
and a 360 day year. The Commitment Fee shall be payable in arrears on the last
Business Day of each calendar quarter occurring after the Closing Date and on
the Liquidity Commitment Termination Date.

         (b) Upfront Fee. DTFC agrees to pay to the Liquidity Agent for the
account of each Liquidity Lender, as applicable, an upfront fee (the "Upfront
Fee") as set forth in the Fee Letter, which shall be payable immediately upon
the Closing Date. In the event that (i) a Liquidity Lender's short-term credit
rating is reduced to below A-1 by S&P, below P-1 by Moody's or below D-1 by DCR
(if rated by DCR) prior to its initial Liquidity Commitment Termination Date,
and (ii) DTFC elects to replace such Liquidity Lender pursuant to the terms of
this Liquidity Agreement, then such Liquidity Lender shall reimburse DTFC for an
amount equal to the unearned portion of the Upfront Fee actually received by
such Liquidity Lender (based on the remaining period from the date of such
replacement to such Liquidity Lender's Scheduled Commitment Termination Date).

                     CERTAIN EURODOLLAR AND OTHER PROVISIONS

         SECTION 5.1. Eurodollar Lending Unlawful. If any Liquidity Lender shall
reasonably determine (which determination shall, upon notice thereof to DTFC and
the other Liquidity Lenders, be conclusive and binding on DTFC) that the
introduction of or any change in or in the interpretation of any law or
regulation makes it unlawful, or any central bank or other Governmental
Authority asserts that it is unlawful, for such Liquidity Lender to make,
continue or maintain any Liquidity Advance as, or to convert any Liquidity
Advance into, a Eurodollar Advance, the obligation of such Liquidity Lender to
make, continue or maintain or convert any such Liquidity Advance as a Eurodollar
Advance shall, upon such determination, forthwith be suspended until such
Liquidity Lender shall notify the Liquidity Agent and DTFC that the
circumstances causing such suspension no longer exist, and DTFC shall
immediately convert (in the manner provided for in Section 3.8) all Eurodollar
Advances of such Liquidity Lender into Base Rate Advances at the end of the then
current Interest Periods with respect thereto or sooner, if required by such law
or assertion.

         SECTION 5.2. Deposits Unavailable. If the Liquidity Agent shall have
reasonably determined that

                  (a) Eurodollar deposits in the relevant amount and for the
         relevant Interest Period are not available to all Reference Lenders in
         the relevant market; or

                  (b) by reason of circumstances affecting all Reference
         Lenders' relevant market, adequate means do not exist for ascertaining
         the interest rate applicable hereunder to Eurodollar Advances; or

                  (c) the Majority Banks have notified the Liquidity Agent that,
         with respect to any interest rate otherwise applicable hereunder to any
         Eurodollar Advances the Interest Period for which has not then
         commenced, such interest rate will not adequately reflect the cost to
         such Majority Banks of making, funding or maintaining their respective
         Eurodollar Advances for such Interest Period,

then, upon notice from the Liquidity Agent to DTFC and the Liquidity Lenders,
the obligations of all Liquidity Lenders under Section 3.6 and Section 3.8 to
make or continue any Liquidity Advance as, or to convert any Liquidity Advances
into, Eurodollar Advances shall forthwith be suspended until the Liquidity Agent
shall notify DTFC and the Liquidity Lenders that the circumstances causing such
suspension no longer exist.

         SECTION 5.3. Increased Costs, etc. DTFC agrees to reimburse each
Liquidity Lender for any increase in the cost to such Liquidity Lender of, or
any reduction in the amount


                                      -20-



<PAGE>   29



of any sum receivable by such Liquidity Lender in respect of, making, continuing
or maintaining (or of its obligation to make, continue or maintain) any
Liquidity Advances as, or of converting (or of its obligation to convert) any
Liquidity Advances into, Eurodollar Advances that arise in connection with any
change in, or the introduction, adoption, effectiveness, interpretation
reinterpretation or phase-in after the date hereof of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of
law) of any court, central bank, regulator or other Governmental Authority,
except for such changes with respect to (i) increased capital costs which are
governed by Section 5.5, (ii) Taxes governed by Section 5.6 (including taxes
imposed by reason of any failure of such Liquidity Lender to comply with its
obligations under clause (b) of Section 5.6) and (iii) taxes imposed by a taxing
authority on or measured by the net income, overall receipts or capital of such
Liquidity Lender or any lending office, branch or any Affiliate thereof and any
franchise taxes or branch taxes imposed by a taxing authority on such Liquidity
Lender or any lending office, branch or any Affiliate thereof; provided,
however, that DTFC shall have no obligation to pay any such additional amount
under this Section 5.3 with respect to any such change unless such Liquidity
Lender shall have notified DTFC of its demand within 90 days after the date upon
which such Liquidity Lender has obtained audited financial statements with
respect to the fiscal year of such Liquidity Lender in which such change
occurred. Such Liquidity Lender shall promptly notify the Liquidity Agent and
DTFC in writing of the occurrence of any such reduction or increase (but in no
event later than the date by which such Liquidity Lender may demand
reimbursement therefor pursuant to the immediately preceding sentence), such
notice to state, in reasonable detail, the reasons therefor and the additional
amount required fully to compensate such Liquidity Lender on an after-tax basis
for such increased cost or reduced amount. Such additional amounts shall be
payable by DTFC directly to such Liquidity Lender within five Business Days of
its receipt of such notice, and such notice shall, in the absence of manifest
error, be conclusive and binding on DTFC.

         SECTION 5.4. Funding Losses. In the event any Liquidity Lender shall
incur any loss or expense (including any loss or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Liquidity Lender to make, continue or maintain any portion of the principal
amount of any Liquidity Advance as, or to convert any portion of the principal
amount of any Liquidity Advance into, a Eurodollar Advance) as a result of

                  (a) any conversion or repayment or prepayment of the principal
         amount of any Eurodollar Advance on a date other than the scheduled
         last day of the Interest Period applicable thereto, whether pursuant to
         Section 4.1 or otherwise;

                  (b) any Liquidity Advances not being made as Eurodollar
         Advances in accordance with the Borrowing Request therefor; or


                                      -21-



<PAGE>   30



                  (c) any Liquidity Advances not being continued as, or
         converted into, Eurodollar Advances in accordance with the
         Continuation/Conversion Notice therefor,

then, upon the written notice of such Liquidity Lender to DTFC (with a copy to
the Liquidity Agent), DTFC shall, within five Business Days of its receipt
thereof, pay directly to such Liquidity Lender such amount as will (in the
reasonable determination of such Liquidity Lender) reimburse such Liquidity
Lender for such loss or expense. Such written notice (which shall include
calculations in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on DTFC.

         SECTION 5.5. Increased Capital Costs. If any change in, or the
introduction, adoption, effectiveness, interpretation or reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other Governmental Authority affects or would affect the amount of capital
required or expected to be maintained by any Liquidity Lender or any Person
controlling such Liquidity Lender, and such Liquidity Lender determines (in its
sole and absolute discretion) that the rate of return on its or such controlling
Person's capital as a consequence of its Liquidity Commitment or the Liquidity
Advances made by such Liquidity Lender is reduced to a level below that which
such Liquidity Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Liquidity Lender to DTFC, DTFC shall pay directly to such
Liquidity Lender within five Business Days additional amounts sufficient to
compensate such Liquidity Lender or such controlling Person on an after-tax
basis for such reduction in rate of return; provided, however, that DTFC shall
have no obligation to pay any such additional amount under this Section 5.5 with
respect to any such change unless such Liquidity Lender shall have notified DTFC
of its demand within 90 days after the date upon which such Liquidity Lender or
controlling Person has obtained audited financial statements with respect to the
fiscal year of such Liquidity Lender or such controlling Person in which such
change occurred. Such Liquidity Lender or such controlling Person shall promptly
notify the Liquidity Agent and DTFC in writing of the occurrence of any such
reduction (but in no event later than the date by which such Liquidity Lender or
controlling Person may demand payment therefor pursuant to the immediately
preceding sentence). A statement of such Liquidity Lender as to any such
additional amount or amounts (including calculations thereof in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
DTFC. In determining such amount, such Liquidity Lender may use any method of
averaging and attribution that it (in its sole and absolute discretion) shall
deem applicable.

         SECTION 5.6.  Taxes.

                  (a) Except to the extent otherwise provided in the proviso to
         clause (iii) of this Section 5.6(a) and the proviso to the sentence
         immediately succeeding such clause (iii), all payments by DTFC of
         principal of, and interest on, the Liquidity Advances and all


                                      -22-



<PAGE>   31



         other amounts payable hereunder (including fees) shall be made free and
         clear of and without deduction for any present or future income,
         excise, stamp or franchise taxes and other taxes, fees, duties,
         withholdings or other charges of any nature whatsoever imposed by any
         taxing authority, but excluding (A) in the case of each Liquidity
         Lender and the Liquidity Agent, taxes imposed on or measured by the net
         income, overall receipts or capital of such Liquidity Lender (or any
         lending office, branch or Affiliate of such Liquidity Lender) or the
         Liquidity Agent and franchise taxes or branch taxes imposed on such
         Liquidity Lender (or any lending office, branch or Affiliate of such
         Liquidity Lender) or the Liquidity Agent, as the case may be, (x) by
         the jurisdiction under the laws of which it is organized or any
         political subdivision thereof or (y) by reason of any connection
         between the jurisdiction imposing such tax and such Liquidity Lender
         (or any lending office, branch or Affiliate thereof) or the Liquidity
         Agent, as the case may be, other than a connection arising solely from
         such Liquidity Lender (or such lending office, branch or Affiliate) or
         the Liquidity Agent, as the case may be, having executed, delivered, or
         performed its obligations under, or received payment under or enforced,
         this Liquidity Agreement, any Liquidity Advance Notes or any other
         Liquidity Document and, (B) in the case of each Liquidity Lender, taxes
         imposed on or measured by the net income, overall receipts or capital
         of such Liquidity Lender (or any lending office, branch or Affiliate of
         such Liquidity Lender) and franchise taxes or branch taxes imposed on
         such Liquidity Lender (or any lending office, branch or Affiliate of
         such Liquidity Lender) by the jurisdiction in which such Liquidity
         Lender's Domestic Office or Eurodollar Office, as the case may be, is
         located or any political subdivision thereof (such non-excluded items
         being called "Taxes"). In the event that any withholding or deduction
         from any payment to be made by DTFC hereunder is required in respect of
         any Taxes pursuant to any Applicable Law then DTFC will

                           (i)   pay directly to the relevant authority the full
                  amount required to be so withheld or deducted;

                           (ii)  promptly forward to the Liquidity Agent an
                  official receipt or other documentation satisfactory to the
                  Liquidity Agent evidencing such payment to such authority; and

                           (iii) pay to the Liquidity Agent for the account of
                  the Liquidity Lenders (or, if applicable, for its own account)
                  such additional amount or amounts as is necessary to ensure
                  that the net amount actually received by each Liquidity Lender
                  and the Liquidity Agent will equal the full amount such
                  Liquidity Lender or the Liquidity Agent, as the case may be,
                  would have received had no such withholding or deduction been
                  required; provided, however, that DTFC shall be entitled to
                  deduct and withhold any Taxes and shall not be required to
                  increase any such amounts payable pursuant to this clause
                  (iii) to the Liquidity Agent for the account of any Liquidity
                  Lender (or, if applicable, for its own account) to


                                      -23-



<PAGE>   32



                  the extent such Taxes are imposed as a result of the failure
                  of such Liquidity Lender or, as applicable, the Liquidity
                  Agent to comply with the requirements of clause (b) of this
                  Section 5.6.

Moreover, if any Taxes are directly asserted against the Liquidity Agent or any
Liquidity Lender with respect to any payment received by the Liquidity Agent or
such Liquidity Lender hereunder, the Liquidity Agent or such Liquidity Lender
may pay such Taxes and promptly notify DTFC of the nature and amount of such
payment and DTFC will promptly pay such additional amounts (including any
penalties, interest or expenses) as is necessary in order that the net amount
received by such person after the payment of such Taxes (including any Taxes on
such additional amount) shall equal the amount such person would have received
had no such Taxes been asserted; provided, however, that DTFC shall not be
required to pay any additional amounts pursuant to this sentence to the
Liquidity Agent for the account of any Liquidity Lender (or, if applicable, for
its own account), or to any Liquidity Lender, to the extent such Taxes are
imposed as a result of the failure of such Liquidity Lender or, as applicable,
the Liquidity Agent to comply with the requirements of clause (b) of this
Section 5.6.

         If DTFC fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Liquidity Agent, for the account of the
respective Liquidity Lenders, the required receipts or other required
documentary evidence, DTFC shall indemnify the Liquidity Lenders for any
incremental Taxes, interest or penalties that may become payable by any
Liquidity Lender as a result of any such failure. For purposes of this Section
5.6, a distribution hereunder by the Liquidity Agent or any Liquidity Lender to
or for the account of any Liquidity Lender shall be deemed a payment by DTFC.

                  (b) Each Liquidity Lender that is not incorporated under the
         laws of the United States (or any State thereof or the District of
         Columbia) and, if the Liquidity Agent is not incorporated under the
         laws of the United States (or any State thereof or the District of
         Columbia), the Liquidity Agent shall:

                           (X)(i) on or before the date of any payment by DTFC
                  under this Liquidity Agreement, any Liquidity Advance Notes or
                  any other Liquidity Document for the account of such Liquidity
                  Lender or the Liquidity Agent, deliver to DTFC and the
                  Liquidity Agent (A) two duly completed copies of United States
                  Internal Revenue Service Form 1001 or 4224, or successor
                  applicable form, as the case may be, and such other forms and
                  certifications as may reasonably be required under applicable
                  law, in order to establish that as of the date thereof such
                  Liquidity Lender or the Liquidity Agent, as the case may be,
                  is entitled to receive all payments under this Liquidity
                  Agreement, any Liquidity Advance Notes or any other Liquidity
                  Document without deduction or withholding of any United States
                  federal income taxes and (B) an Internal

                  Revenue Service Form W-8 or W-9, or successor applicable form,
                  as the case may be, certifying that such Liquidity Lender or
                  the Liquidity Agent, as the case may be, is entitled to an
                  exemption from United States backup withholding taxes;

                           (ii) deliver to DTFC and the Liquidity Agent two
                  further copies of any such form on or before the date that any
                  such form expires or becomes obsolete and after the occurrence
                  of any event requiring a change in the most recent form
                  previously delivered by it to DTFC and the Liquidity Agent;
                  and

                           (iii) if necessary, obtain, at the expense of DTFC,
                  such extensions of time for delivery of such forms as may
                  reasonably be requested by DTFC; or

                           (Y) in the case of any such Liquidity Lender that is
                  not a "bank" within the meaning of Section 881(c)(3)(A) of the
                  Code, (i) furnish to DTFC on or before the date of any payment
                  by DTFC, with a copy to the Liquidity Agent, (A) a certificate

                  "U.S. Tax Compliance Certificate"), (B) two accurate and
                  complete original signed copies of Internal Revenue Service

                  Liquidity Lender's entitlement as of the date of such form to
                  the exemption under Section 881(c) of the Code from U.S.
                  withholding tax on payments of interest under this Liquidity
                  Agreement, any Liquidity Advance Notes or any other Liquidity
                  Document (and deliver to DTFC and the Liquidity Agent two
                  further copies of such form on or before the date the most
                  recently delivered form expires or becomes obsolete and after
                  the occurrence of any event requiring a change in the most
                  recently delivered form and, if necessary, obtain, at the
                  expense of DTFC, any extensions of time reasonably requested
                  by DTFC for the delivery of such forms), and (C) in the case
                  of a Liquidity Lender that is entitled to receive payments
                  under this Liquidity Agreement, any Liquidity Advance Notes or
                  any other Liquidity Documents other than payments of interest,
                  two accurate and complete original signed copies of Internal
                  Revenue Service Form 1001, or successor applicable form

                  date of such form to receive payments other than payments of
                  interest under this Liquidity Agreement, any Liquidity Advance
                  Notes or any other Liquidity Documents without deduction or
                  withholding of any United States federal income taxes (and
                  deliver to DTFC and the Liquidity Agent two further copies of
                  such form on or before the date the most recently delivered
                  form expires or becomes obsolete and after the occurrence of
                  any event requiring a change in the most recently delivered

                  extensions of time reasonably requested by DTFC for the
                  delivery of such forms); and (ii) agree, upon reasonable
                  request of DTFC, to provide to DTFC and the


                                      -25-



<PAGE>   34



                  Liquidity Agent (for the benefit of DTFC and the Liquidity
                  Agent), such other forms as may be reasonably required under
                  Applicable Law in order to establish the legal entitlement of
                  such Liquidity Lender to an exemption from withholding of
                  Taxes with respect to any payments under this Liquidity
                  Agreement, any Liquidity Advance Notes and any other Liquidity
                  Document;

unless in any such case any change in treaty, law or regulation or any change in
any previously published ruling, notice or other similar official Internal
Revenue Service interpretation of a treaty, law or regulation has occurred after
the date such Person becomes a Liquidity Lender hereunder or the Liquidity
Agent, as the case may be, which renders all such forms inapplicable to such
Liquidity Lender or the Liquidity Agent or which would prevent such Liquidity
Lender or the Liquidity Agent from duly completing and delivering any such form
with respect to it and such Liquidity Lender or the Liquidity Agent promptly so
advises DTFC and the Liquidity Agent (in the case of a Liquidity Lender) in
writing. Each Person that shall become a Liquidity Lender or a Liquidity
Participant pursuant to Section 11.11.1 or 11.11.2 shall, upon the effectiveness
of the related transfer, be required to provide all of the forms, certifications
and statements required pursuant to this Section, provided that in the case of a
Liquidity Participant the obligations of such Liquidity Participant, pursuant to
this clause (b) shall be determined as if such Liquidity Participant were a
Liquidity Lender except that such Liquidity Participant shall furnish all such
required forms, certifications and statements to the Liquidity Lender from which
the related participation shall have been purchased.

         SECTION 5.7. Payments, Computations, etc. Unless otherwise expressly
provided, all payments by DTFC pursuant to this Liquidity Agreement, the
Liquidity Advance Notes and any other Liquidity Document shall be made by DTFC
to the Liquidity Agent for the pro rata account, on the basis of Liquidity
Advances Outstanding, or if no Liquidity Advances are outstanding, on the basis
of Liquidity Commitments, of the Liquidity Lenders entitled to receive such
payment. All such payments required to be made to the Liquidity Agent by DTFC
shall be made, without setoff, deduction or counterclaim, not later than 1:00
p.m. (New York City, New York time) on the date due, in same day or immediately
available funds, to the account established pursuant to Section 3.7(a) or such
other account as the Liquidity Agent shall specify from time to time by notice
to DTFC. Funds received after that time shall be deemed to have been received by
the Liquidity Agent on the next succeeding Business Day. The Liquidity Agent
shall promptly remit in same day funds to each Liquidity Lender its share, if
any, of such payments received by the Liquidity Agent for the account of such
Liquidity Lender. Whenever any payment to be made shall otherwise be due on a
day which is not a Business Day, such payment shall (except as otherwise
required by the second proviso of the definition of the term "Interest Period"
with respect to Eurodollar Advances) be made on the next succeeding Business Day
and such extension of time shall be included in computing interest and fees, if
any, in connection with such payment.


                                      -26-



<PAGE>   35



         SECTION 5.8. Sharing of Payments. If any Liquidity Lender shall obtain
any payment or other recovery (whether voluntary or involuntary) on account of
any Liquidity Advance (other than pursuant to the terms of Sections 5.3, 5.4,
5.5 and 5.6) in excess of its pro rata share of payments, on the basis of
Liquidity Advances Outstanding, or if no Liquidity Advances are outstanding, on
the basis of Liquidity Commitments, then or therewith obtained by all Liquidity
Lenders, such Liquidity Lender shall purchase from the other Liquidity Lenders
such participation in Liquidity Advances made by them as shall be necessary to
cause such purchasing Liquidity Lender to share the excess payment or other
recovery with each of them on a pro rata basis, computed on the basis of each
Liquidity Lender's Liquidity Advances Outstanding or Liquidity Commitment, as
the case may be, on the date of such computation; provided, however, that if all
or any portion of the excess payment or other recovery is thereafter recovered
from such purchasing Liquidity Lender, the purchase shall be rescinded to the
extent of such recovery and each Liquidity Lender which has sold a participation
to the purchasing Liquidity Lender shall repay to the purchasing Liquidity
Lender the purchase price to the ratable extent of such recovery together with
an amount equal to such selling Liquidity Lender's ratable share (according to
the proportion of

                  (a) the amount of such selling Liquidity Lender's required
         repayment to the purchasing Liquidity Lender

to

                  (b) the total amount so recovered from the purchasing
         Liquidity Lender)

of any interest or other amount paid or payable by the purchasing Liquidity
Lender in respect of the total amount so recovered. DTFC agrees that any
Liquidity Lender so purchasing a participation from another Liquidity Lender
pursuant to this Section may, to the fullest extent permitted by law, exercise
all its rights of payment with respect to such participation as fully as if such
Liquidity Lender were the direct creditor of DTFC in the amount of such
participation. If under any applicable bankruptcy, insolvency or other similar
law, any Liquidity Lender receives a secured claim to which this Section
applies, such Liquidity Lender shall, to the extent practicable, exercise its
rights in respect of such secured claim in a manner consistent with the rights
of the Liquidity Lenders entitled under this Section to share in the benefits of
any recovery on such secured claim.

         SECTION 5.9. Replacement of Liquidity Lenders. (a) If at any time the
credit rating assigned to the short-term obligations of any Liquidity Lender (an
"Affected Liquidity Lender") is withdrawn or downgraded below the rating then
assigned by S&P, Moody's or DCR (if rated by DCR), respectively, to the
Commercial Paper Notes, DTFC may, upon five Business Days' prior written notice
given to the Liquidity Agent and such Affected Liquidity Lender acceptable to
the Liquidity Agent, replace such Affected Liquidity Lender with an Eligible
Liquidity Lender or a Liquidity Lender already party to this Liquidity Agreement
and


                                      -27-



<PAGE>   36



such replacement shall be made in accordance with clause (a) of Section 11.11.1
and the proviso of clause (b) of this Section 5.9; provided, however, that
payment of the processing fee referred to in clause (B) of Section 11.11.1(a)
shall not be required; and provided further, however, no such replacement
pursuant to this clause (a) shall be effective unless S&P, Moody's and DCR shall
have confirmed in writing to DTFC and the Liquidity Agent that such replacement
(i) would not result in a withdrawal or reduction of the rating by S&P, Moody's
or DCR of the Commercial Paper Notes below the rating then assigned by such
Rating Agency to the Commercial Paper Notes or (ii) if the Commercial Paper
Notes are then rated less than A-1 by S&P, P-1 by Moody's or D-1 by DCR would
result in an upgrade of the rating by S&P, Moody's or DCR of the Commercial
Paper Notes over the rating then assigned by such Rating Agency to the
Commercial Paper Notes.

         (b) In the event that (i) any Liquidity Lender shall have notified the
Liquidity Agent or DTFC (and shall not have retracted such notification) that
its compliance with any of its obligations hereunder would be unlawful, (ii) any
Liquidity Lender fails to extend its Liquidity Commitment upon request, (iii)
DTFC is required pursuant to Section 4.2.1(b) or Sections 5.3 through 5.6 to
make any payment to or on behalf of any Liquidity Lender (or would be so
required on or prior to the next following date on which a payment hereunder
(other than pursuant to Section 5.6) is required to be made to or for any such
Liquidity Lender) or (iv) any Liquidity Lender shall have failed to fund any
Liquidity Advance when required hereunder, then DTFC shall have the right, at
its own expense, upon notice to such Liquidity Lender and the Liquidity Agent,
to require such Liquidity Lender, and such Liquidity Lender hereby agrees, to
transfer and assign without recourse (in accordance with and subject to the

occurrence of any event specified in Sections 9.1.1 through 9.1.10 at the
request, or with the consent, of Liquidity Lenders then holding, in the
aggregate, Liquidity Commitments in excess of 50% of the Aggregate Liquidity
Commitment (or, if the Aggregate Liquidity Commitment shall have been
terminated, Liquidity Lenders then holding, in the aggregate, in excess of 50%
of the principal amount of Liquidity Advances then outstanding), by notice to
DTFC, declare the aggregate principal amount of any Liquidity Advances then
outstanding, together with accrued interest and all fees and other Obligations
hereunder, immediately due and payable whereupon all such principal, accrued
interest, fees and other Obligations hereunder shall become and be forthwith due
and payable, without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by DTFC; provided, however, that in the
case of any Liquidity Agreement Amortization Event under Section 9.1.6 with
respect to DTFC, (A) the Liquidity Commitment of each Liquidity Lender shall
automatically be terminated and (B) all such principal, interest, fees and other
Obligations shall automatically become and be due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by DTFC; (iii) instruct DTFC in writing to cease making
Advances under the Series 1998-1 Notes; and (iv) pursue any other right or
remedy under this Liquidity Agreement and the other CP Program Documents or
under Applicable Law or otherwise.

II Vehicles (or such other amount as shall have been agreed to for this purpose
by DTFC and the Majority Banks at the time that DTFC proposes such Manufacturer
for consideration as an "Eligible Manufacturer" under the CP Program Documents),
in each case, owed by it in respect of any Group II Vehicles turned back in
accordance with the terms of the related Vehicle Disposition Program and such
failure shall continue for 90 days after such aggregate amount shall have become
due and payable or (c) any Event of Bankruptcy shall have occurred with respect
to any Manufacturer.

Commitment of any Liquidity Lender shall have been terminated and DTFC shall

been replaced pursuant to Section 5.9 hereof.

           SECTION 9.4. Action Upon Limited Liquidity Agreement Amortization
Event.

                  (a) If any Limited Liquidity Agreement Amortization Event set

         issued to finance any such purchase or financing.

                  (b) If any Limited Liquidity Agreement Amortization Event set
         forth in Section 9.3.2 shall have occurred and be continuing, then DTFC
         shall not issue Commercial Paper Notes to the extent that after giving
         effect to such issuance (and the use of proceeds thereof), the
         Aggregate Face Amount shall exceed the Program Size (reduced by the
         aggregate Liquidity Commitments of the Liquidity Lenders that have been
         terminated).

                  (c) If any Limited Liquidity Agreement Amortization Event set

                                    ARTICLE X

                               THE LIQUIDITY AGENT

         SECTION 10.1. Actions. Each Liquidity Lender hereby appoints CSFB as
its Liquidity Agent under and for purposes of this Liquidity Agreement, the
Liquidity Advance Notes and each other CP Program Document. Each Liquidity
Lender hereby authorizes the Liquidity Agent to act on behalf of such Liquidity
Lender under this Liquidity Agreement, the Liquidity Advance Notes and each
other CP Program Document and, in the absence of other written instructions from
the Majority Banks received from time to time by the Liquidity Agent (with
respect to which the Liquidity Agent agrees that it will comply, except as
otherwise provided in this Section or as otherwise advised by counsel), to
exercise such powers hereunder and thereunder as are specifically delegated to
or required of the Liquidity Agent by the terms hereof and thereof, together
with such powers as may be reasonably incidental thereto. Each Liquidity Lender
hereby indemnifies (which indemnity shall survive any termination of this
Liquidity Agreement) the Liquidity Agent, pro rata according to such


                                      -49-



<PAGE>   58



Liquidity Lender's Percentage, from and against any and all liabilities,
obligations, losses, damages, claims, costs or expenses of any kind or nature
whatsoever which may at any time be imposed on, incurred by, or asserted
against, the Liquidity Agent in any way relating to or arising out of this
Liquidity Agreement, the Liquidity Advance Notes and any other CP Program
Document, including reasonable attorneys' fees (including the allocated costs of
in-house counsel), and as to which the Liquidity Agent is not reimbursed by
DTFC; provided, however, that no Liquidity Lender shall be liable for the
payment of any portion of such liabilities, obligations, losses, damages,
claims, costs or expenses which are determined by a court of competent
jurisdiction in a final proceeding to have resulted from the Liquidity Agent's
gross negligence or wilful misconduct. The Liquidity Agent shall not be required
to take any action hereunder, under the Liquidity Advance Notes or under any
other CP Program Document, or to prosecute or defend any suit in respect of this
Liquidity Agreement, the Liquidity Advance Notes or any other CP Program
Document, unless it is indemnified hereunder to its satisfaction. If any
indemnity in favor of the Liquidity Agent shall be or become, in the Liquidity
Agent's determination, inadequate, the Liquidity Agent may call for additional
indemnification from the Liquidity Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given.

         SECTION 10.2. Collateral Agreement. Without limiting the authorizations
otherwise set forth in this Article X, each Liquidity Lender hereby authorizes
the Liquidity Agent to execute and deliver the Collateral Agreement and each of
the other CP Program Documents as Liquidity Agent and on behalf of such
Liquidity Lender, with the same effect as if such Liquidity Lender had executed
the Collateral Agreement or such CP Program Document in its own name. Each
Liquidity Lender acknowledges that the Collateral Agreement contains certain
provisions, including, without limitation, Section 7.02 thereof, which give rise
to indemnification obligations in respect of the Collateral Agent on the part of
such Liquidity Lender and such Liquidity Lender hereby agrees to be bound by
such provisions, as the same may from time to time be modified in accordance
with the terms of the Collateral Agreement and this Liquidity Agreement.

         SECTION 10.3. Exculpation. Neither the Liquidity Agent nor any of its
directors, officers, employees or agents shall be liable to any Liquidity Lender
for any action taken or omitted to be taken by it under this Liquidity Agreement
or any other CP Program Document, or in connection herewith or therewith, except
for its own wilful misconduct or gross negligence, nor responsible for any
recitals or warranties herein or therein, nor for the effectiveness,
enforceability, validity or due execution of this Liquidity Agreement or any
other CP Program Document, nor for the creation, perfection or priority of any
Liens purported to be created by any of the CP Program Documents, or the
validity, genuineness, enforceability, existence, value or sufficiency of any
collateral security, nor to make any inquiry respecting the performance by DTFC
of its Obligations hereunder or under any other CP Program Document. Any such
inquiry which may be made by the Liquidity Agent shall not obligate it to make
any further inquiry or to take any action. The Liquidity Agent shall be


                                      -50-



<PAGE>   59



entitled to rely upon advice of counsel concerning legal matters and upon any
notice, consent, certificate, statement or writing which the Liquidity Agent
believes to be genuine and to have been presented by a proper Person. As to any
matters not expressly provided for in this Liquidity Agreement or any other CP
Program Document, the Liquidity Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Banks.

         SECTION 10.4. Successor. The Liquidity Agent may resign as such at any
time upon at least 30 days' prior written notice to DTFC and all Liquidity
Lenders, and the Liquidity Agent may be removed at any time with cause by the
Majority Banks. If the Liquidity Agent at any time shall resign or be removed,
the Majority Banks may appoint (with, if no Potential Liquidity Agreement
Amortization Event or Liquidity Agreement Amortization Event (other than a
Scheduled Liquidity Agreement Amortization Event) then exists, the consent of
DTFC, which consent shall not be unreasonably withheld or delayed) another
Liquidity Lender as a successor Liquidity Agent which shall thereupon become the
Liquidity Agent hereunder. If no successor Liquidity Agent shall have been so
appointed by the Majority Banks, and shall have accepted such appointment,
within 30 days after the retiring Liquidity Agent's giving notice of resignation
or the Majority Banks' removal of the retiring Liquidity Agent, then the
retiring Liquidity Agent may, on behalf of the Liquidity Lenders, appoint a
successor Liquidity Agent, which shall be one of the Liquidity Lenders or an
Eligible Liquidity Lender. The resignation or removal of the Liquidity Agent
shall not become effective until a successor Liquidity Agent has been appointed
and shall have accepted such appointment. Upon the acceptance of any appointment
as Liquidity Agent hereunder by a successor Liquidity Agent, such successor
Liquidity Agent shall be entitled to receive from the retiring Liquidity Agent
such documents of transfer and assignment as such successor Liquidity Agent may
reasonably request, and shall thereupon succeed to and become vested with all
rights, powers, privileges and duties of the retiring Liquidity Agent, and the
retiring Liquidity Agent shall be discharged from its duties and obligations
under this Liquidity Agreement and all other CP Program Documents. After any
retiring Liquidity Agent's resignation or removal hereunder as the Liquidity
Agent, the provisions of

                  (a) this Article X shall inure to its benefit as to any
         actions taken or omitted to be taken by it while it was the Liquidity
         Agent under this Liquidity Agreement; and

                  (b)  Section 11.3 and Section 11.4 shall continue to inure to
         its benefit.

         SECTION 10.5. Liquidity Advances by CSFB. CSFB (and any successor
thereto in its capacity as Liquidity Agent, that is also a Liquidity Lender)
shall have the same rights and powers with respect to (x) the Liquidity Advances
made by it or any of its Affiliates, and (y) the Liquidity Advance Notes held by
it or any of its Affiliates as any other Liquidity Lender and may exercise the
same as if it were not the Liquidity Agent. CSFB (and such


                                      -51-



<PAGE>   60



successor) and its Affiliates may accept deposits from, lend money to, and
generally engage in any kind of business with DTFC or any Affiliate of DTFC as
if CSFB (and such successor) were not the Liquidity Agent hereunder.

         SECTION 10.6. Credit Decisions. Each Liquidity Lender acknowledges that
it has, independently of the Liquidity Agent and each other Liquidity Lender,
and based on such Liquidity Lender's review of the financial information of
DTFC, RCFC, the Lessees and DTAG, this Liquidity Agreement, the other CP Program
Documents (the terms and provisions of which being satisfactory to such
Liquidity Lender) and such other documents, information and investigations as
such Liquidity Lender has deemed appropriate, made its own credit decision to
extend its Liquidity Commitment. Each Liquidity Lender also acknowledges that it
will, independently of the Liquidity Agent and each other Liquidity Lender, and
based on such other documents, information and investigations as it shall deem
appropriate at any time, continue to make its own credit decisions as to
exercising or not exercising from time to time any rights and privileges
available to it under this Liquidity Agreement or any other CP Program Document.

         SECTION 10.7. Copies, etc. The Liquidity Agent shall give prompt notice
to each Liquidity Lender of each notice or request required or permitted to be
given to the Liquidity Agent by DTFC pursuant to the terms of this Liquidity
Agreement (unless concurrently delivered to the Liquidity Lenders by DTFC). The
Liquidity Agent will distribute to each Liquidity Lender each document or
instrument received for its account and copies of all other communications
received by the Liquidity Agent from DTFC for distribution to the Liquidity
Lenders by the Liquidity Agent in accordance with the terms of this Liquidity
Agreement.


                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

         SECTION 11.1. Waivers, Amendments, etc. (a) The provisions of this
Liquidity Agreement and each other CP Program Document to which DTFC is a party

notice of such amendment, modification or waiver is given to each of the Rating
Agencies and the Dealers, (ii) subject to Section 8.2.10 hereof as it relates to
amendments of the CP Program Documents other than this Liquidity Agreement, such
amendment, modification or waiver is in writing and consented to in writing by
DTFC, the Series 1998-1 Letter of Credit Provider and the Majority Banks and
(iii) such amendment, modification or waiver shall not, as evidenced by written
confirmation of the Rating Agencies, result in the downgrading or withdrawal of
the then current ratings of the Commercial Paper Notes by the Rating Agencies;
provided, however, that such written confirmation and consent will not be
required in connection with the extension of a Liquidity Lender's Scheduled
Liquidity Commitment Termination Date pursuant


                                      -52-



<PAGE>   61

"Eligible Vehicle Disposition Program" (with respect to the Series 1998-1
Notes), "Event of Bankruptcy" or "Majority Banks" or any defined term used for
the purpose of any such definition shall require the consent of each Liquidity
Lender and the Series 1998-1 Letter of Credit Provider; and further provided
that any amendment, waiver or other modification that would

                  (i) increase the Liquidity Commitment or the Percentage of any

         any Liquidity Lender shall require the consent of such Liquidity
         Lender;

                  (ii) amend the definition of the Scheduled Maturity Date, the

         Lender affected thereby;

                  (iii) extend the due date for, or reduce the amount of, any
         scheduled repayment or prepayment of principal of or interest on any
         Liquidity Advance of any Liquidity Lender (or reduce the principal
         amount of or rate of interest on any Liquidity Advance of any Liquidity
         Lender) shall require the consent of each Liquidity Lender affected
         thereby;

                  (iv) modify or waive the conditions precedent to the
         effectiveness of this Liquidity Agreement set forth in Article VI shall
         require the consent of each Liquidity Lender;

                  (v) approve the assignment or transfer by DTFC of any of its

                  (vi) release any of the Assigned Collateral from the Lien
         under the Collateral Agreement or the Master Collateral Agency
         Agreement, or release any obligor under any CP Program Document to
         which it is a party except pursuant to the express terms of such CP
         Program Document shall require the consent of each Liquidity Lender,
         provided, however, that the Master Collateral Agent shall release liens
         on Group II Vehicles in accordance with the Master Collateral Agency
         Agreement and the Base Indenture;


                                      -53-



<PAGE>   62



                  (vii) affect adversely the interests, rights or obligations of

         Moody's and DCR.

         (b) Notwithstanding the foregoing provisions of this Section 11.1, DTFC
and the Liquidity Agent may, at any time and from time to time, without the
consent of the Liquidity Lenders, enter into any amendment, supplement or other
modification to this Liquidity Agreement to cure any apparent ambiguity or to

inconsistent with any other provision herein; provided, however, that (i) any
such action shall not have a materially adverse effect on the interests of the
Liquidity Lenders and (ii) a copy of such amendment, supplement or other

         (d) No failure or delay on the part of the Liquidity Agent, any
Liquidity Lender or the holder of any Liquidity Advance Note in exercising any
power or right under this Liquidity Agreement or any other CP Program Document
shall operate as a waiver thereof, nor shall any single or partial exercise of

exercise of any other power or right. No notice to or demand on DTFC in any case
shall entitle it to any notice or demand in similar or other circumstances. No
waiver or approval by the Liquidity Agent, any Liquidity Lender or the holder of

         and any of the other CP Program Documents, and

                  (e) the preparation and negotiation of the legal opinions of
         counsel to each Liquidity Lender, to the extent required by the Rating
         Agencies, up to $2,500 per Liquidity Lender.

DTFC further agrees to pay, and to save the Liquidity Agent and the Liquidity
Lenders harmless from all liability for, (i) any breach by DTFC of any of its
Obligations under this Liquidity Agreement, (ii) all reasonable costs incurred
by the Liquidity Agent or the Liquidity Lenders in enforcing this Liquidity
Agreement against DTFC or its Affiliates and (iii) any stamp, documentary or
other taxes which may be payable in connection with the execution or delivery of

reimburse the Liquidity Agent or such Liquidity Lender upon demand for all
reasonable out-of-pocket expenses incurred by the Liquidity Agent or such
Liquidity Lender in connection with (x) the negotiation of any restructuring or
"work-out", whether or not consummated, of any Obligations and (y) the
enforcement of any Obligations.

         SECTION 11.4. Indemnification. In consideration of the execution and
delivery of this Liquidity Agreement by each Liquidity Lender and the extension
of the Liquidity Commitments, DTFC hereby indemnifies and holds the Liquidity
Agent and each Liquidity Lender and each of their respective officers,
directors, employees and agents (collectively, the "Indemnified Parties")
harmless from and against any and all actions, causes of action, suits, losses,
costs, liabilities and damages, and reasonable expenses incurred in connection
therewith (irrespective of whether any such Indemnified Party is a party to the
action for which indemnification hereunder is sought and including, without
limitation, any liability in connection with the offering and sale of the
Commercial Paper Notes), including reasonable attorneys' fees and disbursements
(collectively, the "Indemnified Liabilities"), incurred by the Indemnified
Parties or any of them as a result of, or arising out of, or relating to

                  (a) any transaction financed or to be financed in whole or in
         part, directly or indirectly, with the proceeds of any Liquidity
         Advance; or

                  (b) the entering into and performance of this Liquidity
         Agreement and any other CP Program Document by any of the Indemnified
         Parties,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or willful misconduct or a breach by such Indemnified Party (or its
agents or employees or any other Person under its control) of any of its
obligations under this Liquidity Agreement, as determined by a final judgment of
a court of competent jurisdiction. If and to the extent that the foregoing


                                      -56-



<PAGE>   65



undertaking may be unenforceable for any reason, DTFC hereby agrees to make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under Applicable Law. The indemnity set forth
in this Section 11.4 shall in no event include indemnification for any Taxes
(which indemnification is provided in Section 5.6). DTFC shall give notice to
the Rating Agencies of any claim for Indemnified Liabilities made under this
Section.

         SECTION 11.5. Survival. The Obligations of DTFC under Sections 5.3,
5.4, 5.5, 5.6, 11.3 and 11.4, and the obligations of the Liquidity Lenders under
Sections 10.1 and 10.2, shall in each case survive any termination of this

termination of all Liquidity Commitments.

         SECTION 11.6. Severability. Any provision of this Liquidity Agreement
or any other CP Program Document which is prohibited or unenforceable in any

remaining provisions of this Liquidity Agreement or such CP Program Document or
affecting the validity or enforceability of such provision in any other
jurisdiction.

         SECTION 11.7. Headings. The various headings of this Liquidity

LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAW PRINCIPLES
THEREOF. This Liquidity Agreement, the Liquidity Advance Notes and the other CP
Program Documents constitute the entire understanding among the parties hereto
with
respect to the subject matter hereof and supersede any prior agreements, written
or oral, with respect thereto.

                  (a) DTFC may not assign or transfer its rights or Obligations
         hereunder, other than pursuant to the Collateral Agreement, without (i)
         the prior written consent of the Liquidity Agent and all Liquidity
         Lenders and (ii) written confirmation from each of the Rating Agencies
         that its then current rating of the Commercial Paper Notes will not be
         reduced or withdrawn as a result thereof; and

                  (b) the rights of sale, assignment and transfer of the
         Liquidity Lenders are subject to Section 11.11.

         SECTION 11.11. Sale and Transfer of Liquidity Advances and Notes;
Participations in Loans and Notes. Each Liquidity Lender may assign, or sell
participations in, its Liquidity Advances and Liquidity Commitment to one or
more other Persons in accordance with this Section 11.11.

         SECTION 11.11.1.  Assignments.  (a)  Any Liquidity Lender,

                  (i) with notice to the Dealers, written confirmation from each
         of the Rating Agencies that its then current rating of the Commercial
         Paper Notes will not be reduced or withdrawn as a result thereof and
         the written consent of DTFC (which consent shall not be unreasonably
         withheld), the Liquidity Agent (which consent shall not be unreasonably
         withheld) may at any time assign and delegate to an Eligible Liquidity
         Lender, and

                  (ii) with ten days' prior notice to the Rating Agencies, DTFC,
         the Liquidity Agent and the Dealers, may assign and delegate to any of
         its Affiliates with a credit rating assigned to its short-term
         obligations by each Rating Agency that is not lower than the rating
         then assigned by such Rating Agency to the Commercial Paper Notes, and
         with the written consent of DTFC (which consent shall not be
         unreasonably withheld) may at any time assign and delegate to any other
         Liquidity Lender

(each Person described in either of the foregoing clauses as the Person to whom
such assignment and delegation is to be made, being hereinafter referred to as
an "Assignee Lender"), all or any fraction of such Liquidity Lender's total
Liquidity Advances and Liquidity Commitment (which assignment and delegation
shall be of a constant, and not a varying, percentage of all the assigning
Liquidity Lender's Liquidity Advances and Liquidity Commitment) in a minimum
aggregate amount of $5,000,000; provided, however, that (x) any such Assignee
Lender will comply, if applicable, with the provisions contained in the last
sentence of Section 5.6 and (y) the minimum aggregate amount of total Liquidity
Commitment and Liquidity Advances, if any, retained by such Liquidity Lender
shall be $5,000,000; provided further, however, that, DTFC and the Liquidity
Agent shall be entitled to continue to deal solely and directly with such
Liquidity Lender in connection with the interests so assigned and delegated to
an Assignee Lender until


                                      -58-



<PAGE>   67



                  (A) such Assignee Lender shall have executed and delivered to
         DTFC and the Liquidity Agent a Liquidity Lender Assignment Agreement,
         accepted by the Liquidity Agent;

                  (B) the processing fees described below shall have been paid;
         and

                  (C) such Assignee Lender shall have delivered an opinion of
         counsel acceptable to the Rating Agencies regarding the enforceability
         of such Assignee Lender's Liquidity Commitment.

From and after the date that the Liquidity Agent accepts such Liquidity Lender
Assignment Agreement, (x) the Assignee Lender thereunder shall be deemed
automatically to have become a party hereto and to the extent that rights and
obligations hereunder have been assigned and delegated to such Assignee Lender
in connection with such Liquidity Lender Assignment Agreement, shall have the
rights and obligations of a Liquidity Lender hereunder and under the other CP
Program Documents, and (y) the assignor Liquidity Lender, to the extent that
rights and obligations hereunder have been assigned and delegated by it in
connection with such Liquidity Lender Assignment Agreement, shall be released
from its obligations hereunder and under the other CP Program Documents. Within
five Business Days after its receipt of notice that the Liquidity Agent has
received an executed Liquidity Lender Assignment Agreement, DTFC shall, upon
receipt of the Liquidity Advance Notes evidencing such assignor Liquidity
Lender's Liquidity Advance and Liquidity Commitment, execute and deliver to the
Liquidity Agent (for delivery to the relevant Assignee Lender) new Liquidity
Advance Notes evidencing such Assignee Lender's assigned Liquidity Advances and
Liquidity Commitment and, if the assignor Liquidity Lender has retained a
portion of its Liquidity Advances and Liquidity Commitment hereunder,
replacement Liquidity Advance Notes in the principal amount of the Liquidity
Advances and Liquidity Commitment so retained by the assignor Liquidity Lender
hereunder (such Liquidity Advance Notes to be in exchange for, but not in
payment of, those Liquidity Advance Notes then held by such assignor Liquidity
Lender). Each such Liquidity Advance Note shall be dated the date of the
predecessor Liquidity Advance Notes. The assignor Liquidity Lender shall mark
the predecessor Liquidity Advance Notes "exchanged" and deliver them to DTFC.
Accrued interest on that part of the predecessor Liquidity Advance Notes
evidenced by the new Liquidity Advance Notes, and accrued fees, shall be paid as
provided in the Liquidity Lender Assignment Agreement. Accrued interest on that
part of the predecessor Liquidity Advance Notes evidenced by the replacement
Liquidity Advance Notes shall be paid to the assignor Liquidity Lender. Accrued
interest and accrued fees shall be paid at the same time or times provided in
the predecessor Liquidity Advance Notes and in this Liquidity Agreement. Such
assignor Liquidity Lender or such Assignee Lender must also pay a processing fee
to the Liquidity Agent upon delivery of any Liquidity Lender Assignment
Agreement in the amount of $2,500. Such assignor Liquidity Lender and such
Assignee Lender (and not DTFC) shall pay any legal expenses incurred by the
Liquidity Agent in the


                                      -59-

review, documentation and closing of such assignment. Any attempted assignment
and delegation not made in accordance with this Section 11.11.1 shall be null
and void.

         (b) Notwithstanding any other provision set forth in this Liquidity
Agreement, any Liquidity Lender may at any time create a security interest in
all or any portion of its rights under this Liquidity Agreement (including,
without limitation, the Liquidity Advances owing to it and the Liquidity Advance
Notes held by it) in favor of any Federal Reserve Bank in accordance with
Regulation A of the Board of Governors of the Federal Reserve System.

         SECTION 11.11.2. Participations. Any Liquidity Lender may at any time
sell to one or more commercial banks or other financial institutions (each of
such commercial banks and financial institutions being herein called a
"Liquidity Participant") participating interests in any of the Liquidity
Advances, Liquidity Commitment or other interests of such Liquidity Lender
hereunder; provided, however, that

                  (a) no participation contemplated in this Section 11.11.2
         shall relieve such Liquidity Lender from its Liquidity Commitment or
         its other obligations hereunder or under any other CP Program Document
         to which such Liquidity Lender is a party;

                  (b) each participation shall be in a minimum aggregate amount
         of $5,000,000 or a smaller amount as may be agreed to by DTFC and the
         Liquidity Agent;

                  (c) such Liquidity Lender shall remain solely responsible for
         the performance of its Liquidity Commitment and such other obligations;

                  (d) DTFC and the Liquidity Agent shall continue to deal solely
         and directly with such Liquidity Lender in connection with such
         Liquidity Lender's rights and obligations under this Liquidity
         Agreement and each of the other CP Program Documents to which such
         Liquidity Lender is a party;

                  (e) no Liquidity Participant, unless such Liquidity
         Participant is an Affiliate of such Liquidity Lender, or is itself a
         Liquidity Lender, shall be entitled to require such Liquidity Lender to
         take or refrain from taking any action hereunder or under any other CP
         Program Document, except that such Liquidity Lender may agree with any
         Liquidity Participant that such Liquidity Lender will not, without such
         Liquidity Participant's consent, take any actions of the type described
         in the first proviso of Section 11.1(a) or clauses (i) through (vii)
         and clauses (ix) and (x) of Section 11.1(a);

                  (f) DTFC shall not be required to pay any amount under this
         Liquidity Agreement that is greater than the amount which it would have
         been required to pay had no participating interest been sold; and


                                      -60-



<PAGE>   69



                  (g) such Liquidity Lender shall comply with any obligation to
         withhold taxes or any filing or reporting requirements imposed under
         Applicable Law relating to such Liquidity Participant and DTFC and
         Liquidity Agent shall continue to deal solely and directly with such
         Liquidity Lender in connection with such matters.

DTFC acknowledges and agrees that, to the extent permitted by Applicable Law,
each Liquidity Participant, subject to clauses (d) and (f) above, for purposes
of Sections 5.3, 5.4, 5.5, 5.6, 5.8, 11.3, 11.4, 11.13 and 11.16 shall be
considered a Liquidity Lender; provided, that no Liquidity Participant shall be
entitled to receive any greater payment under Section 5.3, 5.4 or 5.5 than the
Liquidity Lender that transferred such rights to such Liquidity Participant
would have been entitled to receive with respect to such rights, unless such
transfer is made with DTFC's prior written consent. No Liquidity Participant
shall have direct rights against DTFC.

         SECTION 11.12. Other Transactions. Nothing contained herein shall
preclude the Liquidity Agent or any other Liquidity Lender from engaging in any
transaction, in addition to those contemplated by this Liquidity Agreement or
any other CP Program Document, with DTFC or any of its Affiliates in which DTFC
or such Affiliate is not restricted hereby from engaging with any other Person.

         SECTION 11.13. Bankruptcy Petition Against DTFC. The Liquidity Agent
and each Liquidity Lender hereby covenants and agrees that, prior to the date
which is one year and one day after the payment in full of all Commercial Paper
Notes Outstanding, it will not institute against, or join any other Person in
instituting against, DTFC or RCFC, any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings or other similar proceeding under the laws
of the United States or any state of the United States. In the event that any
Liquidity Lender takes action in violation of this Section 11.13, DTFC agrees,
for the benefit of the Holders, that it shall file an answer with the bankruptcy
court or otherwise properly contest the filing of such a petition by the
Liquidity Lender against DTFC or the commencement of such action and raise the
defense that such Liquidity Lender has agreed in writing not to take such action
and should be estopped and precluded therefrom and such other defenses, if any,
as its counsel advises that it may assert; and such Liquidity Lender acting in
violation of this Section 11.13 shall be liable for and pay the costs and
expenses of DTFC incurred in connection therewith. The provisions of this
Section 11.13 shall survive the termination of this Liquidity Agreement, and,
with respect to the Liquidity Agent, the resignation or removal of the Liquidity
Agent and, with respect to any Liquidity Lender, the replacement of such
Liquidity Lender.

         SECTION 11.14. Limited Recourse to DTFC; No Recourse. (a) The Liquidity
Agent and each Liquidity Lender agree that the Obligations of DTFC to the
Liquidity Agent and such Liquidity Lender hereunder shall be payable in the
order and priority set forth in Section 2.01 and 5.02(b), as applicable, of the
Collateral Agreement. Such Obligations shall be due and


                                      -61-



<PAGE>   70



payable only to the extent that DTFC's Assets and the Series 1998-1 Letter of
Credit are sufficient to pay such Obligations. No claims of the Liquidity Agent
or any Liquidity Lender arising under or in connection with the Collateral
Agreement are intended to be impaired or waived by this Section 11.14(a).

         (b) Without limitation to the Obligations of DTFC hereunder, no
recourse shall be had for the payment of any amount owing in respect of
Liquidity Advances or for the payment of any fee hereunder or any other
obligation or claim arising out of or based upon this Liquidity Agreement, the
Liquidity Advance Notes or any other CP Program Document against any
stockholder, employee, officer, director, Affiliate or incorporator of DTFC
based on their status as such or their actions in connection therewith. The
provisions of this Section 11.14(b) shall survive the termination of this
Liquidity Agreement, and with respect to the Liquidity Agent the resignation or
removal of the Liquidity Agent and with respect to any Liquidity Lender the
replacement of such Liquidity Lender.

         SECTION 11.15. Survival of Representations and Warranties. All
covenants, agreements, representations and warranties made by DTFC herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Liquidity Agreement or any other CP Program Document shall
be considered to have been relied upon by the Liquidity Lenders and shall
survive the execution and delivery of this Liquidity Agreement and the making by
the Liquidity Lenders of the Liquidity Advances, and the execution and delivery
to the Liquidity Lenders of the Liquidity Advance Notes evidencing such
Liquidity Advances, regardless of any investigation made by the Liquidity
Lenders or on their behalf and shall continue so long as and until such time as
all Obligations hereunder and all Indebtedness under the Commercial Paper Notes
shall have been paid in full and the Liquidity Lenders no longer have any
Liquidity Commitments hereunder.

         SECTION 11.16. Confidentiality. Each Liquidity Lender agrees that it
shall not disclose any Confidential Information to any Person without the prior
written consent of DTFC or DTAG, other than (a) to the Liquidity Lender's
Affiliates and their officers, directors, employees, agents and advisors and to
actual or prospective assignees and participants, and then only on a
confidential basis, (b) as required by any law, rule or regulation or judicial
process of which DTFC or DTAG, as the case may be, has knowledge (and DTFC and
DTAG shall be deemed to have knowledge of any general requirement that a
Liquidity Lender disclose Confidential Information to bank examiners or other
regulatory agencies having jurisdiction over the Liquidity Lender); provided
that a Liquidity Lender may disclose Confidential Information as required by any
law, rule or regulation or judicial process of which DTFC or DTAG, as the case
may be, does not have knowledge if such Liquidity Lender is prohibited by law
from disclosing such requirement to DTFC or DTAG, as the case may be, or (c) in
the course of litigation with DTFC or DTAG, the Liquidity Agent or any other
Liquidity Lender.

         "Confidential Information" means information that DTFC or DTAG
furnishes to a Liquidity Lender on a confidential basis, but does not include
any such information that is or becomes generally available to the public other
than as a result of a disclosure by any Liquidity Lender or other Person to
which a Liquidity Lender delivered such information or that is or becomes
available to such Liquidity Lender from a source other than DTFC or DTAG,
provided that such source is not (1) known to such Liquidity Lender to be bound
by a confidentiality agreement with DTFC or DTAG, as the case may be, or (2)
known to such Liquidity Lender to be otherwise prohibited from transmitting the
information by a contractual, legal or fiduciary obligation.

         SECTION 11.17. Jurisdiction; Consent to Service of Process. ALL
JUDICIAL PROCEEDINGS BROUGHT AGAINST DTFC OR ANY LIQUIDITY LENDER WITH RESPECT
TO THIS LIQUIDITY AGREEMENT OR ANY OTHER CP PROGRAM DOCUMENT MAY BE BROUGHT IN
ANY STATE OR (TO THE EXTENT PERMITTED BY LAW) FEDERAL COURT OF COMPETENT
JURISDICTION IN THE STATE OF NEW YORK AND BY EXECUTION AND DELIVERY OF THIS
LIQUIDITY AGREEMENT, DTFC AND THE LIQUIDITY LENDERS EACH ACCEPTS FOR ITSELF AND
IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE
NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS, AND IRREVOCABLY AGREES TO BE
BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS LIQUIDITY
AGREEMENT. DTFC DESIGNATES AND APPOINTS CT CORPORATION, 1633 BROADWAY, NEW YORK,
NEW YORK 10019, AND EACH LIQUIDITY LENDER DESIGNATES AND APPOINTS ITS UNITED
STATES DOMESTIC OFFICE SPECIFIED ON THE SIGNATURE PAGES HEREOF, AND SUCH OTHER
PERSONS AS MAY HEREAFTER BE SELECTED BY DTFC OR SUCH LIQUIDITY LENDER
IRREVOCABLY AGREEING IN WRITING TO SERVE, AS ITS AGENT TO RECEIVE ON ITS BEHALF,
SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDINGS IN ANY SUCH COURT, SUCH SERVICE
BEING HEREBY ACKNOWLEDGED BY DTFC AND EACH LIQUIDITY LENDER TO BE EFFECTIVE AND
BINDING SERVICE IN EVERY RESPECT. A COPY OF SUCH PROCESS SO SERVED SHALL BE
MAILED BY REGISTERED MAIL TO DTFC OR SUCH LIQUIDITY LENDER SO SERVED AT ITS
ADDRESS PROVIDED IN THE APPLICABLE SIGNATURE PAGE HERETO, EXCEPT THAT, UNLESS
OTHERWISE PROVIDED BY APPLICABLE LAW, ANY FAILURE TO MAIL SUCH COPY SHALL NOT
AFFECT THE VALIDITY OF SERVICE OF PROCESS. IF ANY AGENT APPOINTED BY DTFC OR
SUCH LIQUIDITY LENDER REFUSES TO ACCEPT SERVICE, DTFC AND EACH LIQUIDITY LENDER
HEREBY AGREES THAT SERVICE UPON IT BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE.
NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF ANY

LIQUIDITY LENDER OR THE COLLATERAL AGENT TO BRING PROCEEDINGS AGAINST DTFC IN
THE COURTS OF ANY OTHER JURISDICTION.

         SECTION 11.18. Waiver of Jury Trial. THE LIQUIDITY AGENT, THE LIQUIDITY
LENDERS AND DTFC HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY
RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS LIQUIDITY
AGREEMENT OR ANY OTHER CP PROGRAM DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE COLLATERAL

TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE
LIQUIDITY AGENT AND THE LIQUIDITY LENDERS ENTERING INTO THIS LIQUIDITY AGREEMENT
AND EACH SUCH OTHER CP PROGRAM DOCUMENT.

         SECTION 11.19. Waiver of Set-Off. Each Liquidity Lender hereby waives
and relinquishes any right that it has or may have to set-off or to exercise any
banker's lien or any right of attachment or garnishment with respect to any
funds at any time and from time to time on deposit in, or otherwise to the
credit of, any account and any claims of DTFC therein or with respect to any
right to payment from DTFC, it being understood, however, that nothing contained
in this Section 11.19 shall, or is intended to, derogate from the assignment and
security interest granted to the Collateral Agent under the Collateral Agreement
or impair any rights of the Liquidity Lenders, the Liquidity Agent or the
Collateral Agent thereunder.

         Re:  Dollar Thrifty Funding Corp. - Commercial Paper


Ladies and Gentlemen:

         This will confirm the arrangements made with Bankers Trust Company
(the "Depositary") by the undersigned, Dollar Thrifty Funding Corp. ("DTFC" or
the "Issuer"), whereby you have agreed to act as depositary for safekeeping of
certain short-term promissory notes of DTFC (the "Commercial Paper Notes") and
as issuing and paying agent on behalf of DTFC in connection with the issuance
and payment of the Commercial Paper Notes, and to undertake certain obligations
as described below on behalf of holders of the Commercial Paper Notes.  The
Depositary has advised the undersigned that it has arranged for The Depository
Trust Company ("DTC" or the "Sub-Agent") to act as its sub-agent for certain
purposes of this Depositary Agreement (as amended, supplemented, amended and
restated or otherwise modified from time to time in accordance with the terms
hereof, this "Agreement").

         The Commercial Paper Notes will be issued on the terms and subject to
the conditions set forth herein and pursuant to the Liquidity Agreement (as
such agreement may be amended, supplemented, amended and restated or otherwise
modified from time to time in accordance with its terms, the "Liquidity
Agreement"), dated as of March 4, 1998, among DTFC, certain financial
institutions as Liquidity Lenders (the "Liquidity Lenders") and Credit Suisse
First Boston, a Swiss banking corporation (the "Liquidity Agent"), and be

herein and not otherwise defined herein shall have the meanings set forth for
such terms in Annex A to, or incorporated by reference in, the Liquidity
Agreement.

         The Commercial Paper Notes will be entitled to the benefits of this
Agreement, the Liquidity Agreement, the Collateral Agreement, the Base
Indenture, the Series 1998-1 Supplement and the Series 1998-1 Letter of Credit.
<PAGE>   4
         This Agreement will govern your rights, powers and duties as such
Depositary, issuing and paying agent and, in certain circumstances, as agent
with respect to the Commercial Paper Notes issued pursuant to this Agreement.
No implied covenants shall be read into this Agreement against you.  You shall
have no liability to DTFC, any Liquidity Lender, the Credit Enhancer or the
Holder of any Commercial Paper Note for the performance of any of the terms of
the Liquidity Agreement, the Collateral Agreement, the Base Indenture, the
Series 1998-1 Supplement or the Series 1998-1 Letter of Credit except as
expressly provided herein.

         SECTION 1.  Establishment of Accounts; Proceeds of Commercial Paper
Notes.  For the purposes of this Agreement and the Liquidity Agreement you have
established, in the name of DTFC for the exclusive benefit of the Holders, from
time to time, of the Commercial Paper Notes Outstanding, a segregated trust
account in the corporate trust department at Bankers Trust Company, Account No.
25291 (being referred to herein and in the Liquidity Agreement as the
"Commercial Paper Account") over which you shall have exclusive dominion and
control and the sole right of withdrawal.  All proceeds of the sale on any day
of Commercial Paper Notes issued hereunder shall be deposited by you in the
Commercial Paper Account to the extent necessary to provide for the payment of
unpaid matured Commercial Paper Notes or Commercial Paper Notes maturing on
such day, whether or not presented to the Depositary for payment; the proceeds
in excess of the amount required to pay unpaid matured Commercial Paper Notes
or Commercial Paper Notes maturing on such day, whether or not presented to the
Depositary for payment, shall be remitted to the Collateral Agent for deposit
into the Collateral Account on such day.  All funds at any time on deposit in
the Commercial Paper Account shall be held in trust by you for the exclusive
benefit of the Holders, from time to time, of the Commercial Paper Notes
Outstanding in accordance with the terms of this Agreement; and no application
shall be made of such funds except to repay advances by you made pursuant to
Section 5 hereof or to pay matured Commercial Paper Notes in accordance with
the terms hereof.  DTFC shall have no legal, equitable or beneficial interest
in the Commercial Paper Account.  You agree to give DTFC, the Liquidity Agent,
the Rating Agencies and the Dealers immediate notice if you receive written
notice that the Commercial Paper Account or any funds on deposit in the
Commercial Paper Account have become subject to any stay, writ, judgment,
warrant of attachment, execution or similar process.

         SECTION 2.  Commercial Paper Notes Delivered for Safekeeping.  At any
time and from time to time during the term of this Agreement, DTFC may deliver
to your attention at your address set forth in Section 12, Commercial Paper
Notes in substantially the form of Exhibit A to this Agreement (the
"Certificated Notes") which shall be consecutively numbered and bear such other
identification as DTFC may deem appropriate and shall be manually signed or
signed in facsimile in such manner as is acceptable to you on behalf of DTFC by
an Authorized Signatory (as defined below) of DTFC (notwithstanding whether
such person shall thereafter cease to be an Authorized Signatory), but shall
otherwise be incomplete.  The Depositary shall not have any responsibility to
DTFC to determine by what means a facsimile signature may have been affixed to
the Commercial Paper Notes or to determine whether any facsimile signature or
manual signature is genuine or if such facsimile signature or manual signature
resembles the specimen





                                      -2-
<PAGE>   5
signature on file with the Depositary.  Each Commercial Paper Note (including
any Master Note (as defined in Section 6(b) hereof)), or group of Commercial
Paper Notes at one time, delivered to you shall be accompanied by a letter from
DTFC identifying the Commercial Paper Note or Commercial Paper Notes
transmitted therewith, and you shall acknowledge receipt of such Commercial
Paper Note or Commercial Paper Notes on the copy of such letter or some other
form of written receipt deemed appropriate by you and DTFC at the time of
delivery to you of such Commercial Paper Note or Commercial Paper Notes.
Pending the issuance of Commercial Paper Notes as provided in Section 3 hereof,
all Commercial Paper Notes delivered to you shall be held by you for the
account of DTFC for safekeeping in accordance with the Depositary's customary
practices.  DTFC shall bear the sole risk of wastage of Certificated Notes as a
result of administrative or operational errors during the process of their
completion pursuant to this Agreement, other than errors attributable to the
Depositary's gross negligence or willful misconduct.  DTFC shall maintain with
the Depositary at all times a supply of Certificated Notes sufficient to enable
the Depositary to perform the operations contemplated by this Agreement.  The
Depositary shall forward to DTFC the original and all copies of any matured,
spoiled, mutilated, or incorrectly completed Certificated Note, properly
canceled.

         Prior to the issuance of any Commercial Paper Notes, DTFC will furnish
to you, and from time to time hereafter may furnish to you, a certificate
(substantially in the form of Exhibit B hereto) (hereinafter called an
"Incumbency Certificate") of the Secretary or an Assistant Secretary of DTFC,

officers or agents ("Authorized Signatories") of DTFC authorized to execute
Commercial Paper Notes (including the Master Notes) on behalf of DTFC, and (ii)
the officers or agents ("Authorized Representatives") of DTFC who are otherwise
authorized to act and give instructions and notices on behalf of DTFC
hereunder.  Until you receive a subsequent Incumbency Certificate, or unless a
Designated Person (as defined below) shall have actual knowledge of the lack of
authority of any individual, you shall be entitled to rely on the last such
Incumbency Certificate delivered to you for purposes of determining Authorized
Signatories and Authorized Representatives.

         For purposes of this Agreement, you hereby acknowledge that any
Managing Director, Vice President, Assistant Vice President, Assistant
Secretary or Assistant Treasurer of your Corporate Trust and Agency Group in
New York, New York, shall be authorized to act hereunder on your behalf as a
designated person (each, a "Designated Person") and to receive notices and
instructions delivered hereunder.

time during the term of this Agreement, and upon your timely receipt of written

the party to whom such Book Entry CP Notes shall be issued.

         Notwithstanding the foregoing, no Commercial Paper Note shall be
issued hereunder if,

                 (A)      DTFC and the Depositary have received written
         instructions then in effect from the Liquidity Agent (copies of which
         will also be sent to the Dealer), given in accordance with Section 2.1
         of the Liquidity Agreement not to issue or deliver Commercial Paper
         Notes because (i) DTFC shall have terminated the Aggregate Liquidity
         Commitment pursuant to Section 3.3 of the Liquidity Agreement, (ii)
         the Aggregate Liquidity Commitment is otherwise terminated in whole
         for any reason in accordance with the Liquidity Agreement, (iii) the
         Commercial Paper Account or any funds on





                                      -4-

         deposit in, or otherwise to the credit of, the Commercial Paper
         Account are or have become subject to any stay, writ, judgment,
         warrant of attachment, execution or similar process; provided,
         however, that if any such stay, writ, judgment, warrant or attachment,
         execution or similar process is removed or dismissed, DTFC may
         recommence the issuance and sale of Commercial Paper Notes, or (iv)
         any other condition precedent to issuance in Section 2.1 of the
         Liquidity Agreement shall not have been met,

                 (B)      after giving effect to such issuance and the use of
         the proceeds thereof, the sum of the Aggregate Outstanding CP and the
         aggregate principal amount of all Liquidity Advances Outstanding
         would, net of any amounts on deposit at such time in the Collateral
         Account and the Series 1998-1 Collection Account set aside for the
         repayment of the principal of Liquidity Advances, exceed the Aggregate
         Liquidity Commitment plus the Series 1998-1 Letter of Credit Amount
         (which determination shall be made by the Depositary by reference to
         the information to be set forth in the report referred to below),

                 (C)      after giving effect to such issuance and the use of
         proceeds thereof, the Aggregate Outstandings would exceed the CP
         Borrowing Base,

                 (D)      you shall have received written notice that any
         condition precedent specified in Section 2.2 of the Liquidity
         Agreement with respect to such issuance has not been satisfied,

                 (E)     you shall have received written notice that any
         Liquidity Agreement Amortization Event or any Limited Liquidity
         Agreement Amortization Event as specified in Sections 9.2 and 9.4 of
         the Liquidity Agreement has occurred, or

                 (F)      you shall have received notice that any of the
         Accounts (as defined in Section 5.01 of the Collateral Agreement) or
         the Series 1998-1 Cash Collateral Account is subject to any stay,
         writ, judgment, warrant of attachment, execution or other similar
         process as specified in Section 5.01 of the Collateral Agreement.

In this connection the Collateral Agent will provide you at the opening of
business on each such day of issuance with a report based on information as of
the immediately preceding Business Day as to the aggregate principal amount of
all Liquidity Advances Outstanding and interest accrued thereon and the
information required to make the determinations set forth in clauses (B) and
(C) above, and the Series 1998-1 Letter of Credit Amount and the CP Borrowing
Base or any change in any of such amounts, and satisfaction of the conditions
precedent referred to in clause (D) above, and at the time of delivering or
issuing Commercial Paper Notes you may rely on the last such report so received
in determining the amount of Commercial Paper Notes that may then be issued.
In addition, if the Collateral Agent is unable to obtain such information
electronically from the Depositary or the Dealers and the Collateral Agent has
requested such notification, you shall notify the Collateral Agent on each day
of the Aggregate Face Amount of Commercial Paper Notes Outstanding as reflected
by your records.  The Depositary shall make such





                                      -5-
<PAGE>   8
information electronically or otherwise available to DTFC, the Collateral Agent
and the Liquidity Agent.  The Depositary shall also make available to DTFC
pursuant to "Noteline Direct" under the terms specified in Exhibit F hereto the
information required by DTFC for purposes of calculating the CP Rate.  If any
information required to be provided by the Collateral Agent hereunder is not
available to the Collateral Agent, DTFC agrees to provide such information to
the Collateral Agent to the extent DTFC possesses such information.

         (b)  No Commercial Paper Note will be authenticated and delivered, and
no Book Entry Issuance Instruction shall be given, by you unless you shall have
received, in your reasonable judgment, complete instructions from an Authorized
Representative as to the matters specified above in clause (i)(A) and clause
(ii) of paragraph (a) of this Section 3 and, in the case of Certificated Notes
as specified above in clause (i)(A) and (C) of paragraph (a) of this Section 3.
Any instructions given to you by an Authorized Representative to authenticate
and deliver Certificated Notes or to enter a Book Entry Issuance Instruction
hereunder shall constitute a representation and warranty on the part of DTFC
that (i) such Commercial Paper Note is the valid, enforceable and binding
obligation of the Issuer; (ii) such Commercial Paper Note is being issued in a
transaction exempt from registration under the Securities Act of 1933, as
amended, and any applicable state securities law; (iii) the issuance of such
Commercial Paper Notes will not violate or contravene any applicable law, rule,
regulation, order or contractual agreement binding upon DTFC (including, as
appropriate and without limitation, any securities law or law pertaining to
investment companies or any order of any court, governmental agency or
regulatory authority) and will be in conformity with the terms hereof and of
the Liquidity Agreement and all such Commercial Paper Notes are legal, valid
and binding and enforceable against DTFC in accordance with their terms.

         Notwithstanding any instructions received by you from an Authorized
Representative, you shall not deliver Commercial Paper Notes or enter any Book
Entry Issuance Instruction on any date pursuant to such instructions if a
Designated Person shall receive by 9:00 a.m. (New York City time) on such date
written instructions from the Liquidity Agent pursuant to Section 2.1(a) of the
Liquidity Agreement instructing the Depositary not to deliver Commercial Paper
Notes or to enter Book Entry Issuance Instructions, until such written
instructions from the Liquidity Agent are revoked or superseded by further
instructions from the party originally giving the same.

         Any telephonic or electronic instructions given to you by an
Authorized Representative shall be confirmed in writing or electronically by
such Authorized Representative within twenty-four hours after the same are
received by you, and you shall incur no liability for acting in accordance with
any such telephonic instructions reasonably believed by you in good faith to
have been given by an Authorized Representative.

         DTFC is granted a personal, non-transferable and non-exclusive right
to use the instruction and reporting communication service Noteline Direct
("Noteline Direct") to transmit through the Noteline Direct system instructions
made pursuant to Section 3 hereof.  DTFC may,





                                      -6-
<PAGE>   9
by separate agreement between DTFC and one or more of the Dealers (each, an
"Agent"), authorize the Agent(s) to access Noteline Direct directly for the
purposes of transmitting instructions to you or obtaining reports with respect
to the Commercial Paper Notes.

         DTFC acknowledges that (a) some or all of the services utilized in
connection with Noteline Direct are furnished by Digital Transactions Inc.
("DTI"), Dynamic Microprocessor Associates Inc. ("DMA") and Bankers Trust
Company, (b) Noteline Direct is provided to DTFC "AS IS" without warranties or
representations of any kind whatsoever by DTI, DMA or you, and (c) Noteline
Direct is proprietary and confidential property disclosed to DTFC in confidence
and only on the terms and conditions and for the purposes set forth in this
Agreement.

         By this Agreement, DTFC acquires no title, ownership or sublicensing
rights whatsoever in Noteline Direct or in any trade secret, trademark,
copyright or patent of your bank, DTI, or DMA now or to become applicable to
Noteline Direct.  DTFC may not transfer, sublicense, assign, rent, lease,
convey, modify, translate, convert to a programming language, decompile,
disassemble, recirculate, republish or redistribute Noteline Direct for any
purpose without your prior written consent and, where necessary, DTI and DMA
(except for the access to Noteline Direct by the Agent(s) as provided in this
section).

         In the event (a) any action is taken or threatened which may result in
a disclosure or transfer of Noteline Direct or any part thereof, other than as
authorized by this Agreement, or (b) the use of any trademark, trade name,
service mark, service name, copyright or patent of your bank, DTI or DMA by
DTFC amounts to unfair competition, or otherwise constitutes a possible
violation of any kind, then you, DTI and DMA shall each have the right to take
any and all action deemed necessary to protect their rights in Noteline Direct,
and to avoid the substantial and irreparable damage which would result from
such disclosure, transfer or use, including the immediate termination of DTFC's
right to use Noteline Direct.

         To permit the use of Noteline Direct to issue instructions or obtain
reports with respect to the Commercial Paper Notes, you will supply DTFC with
an identification number and initial passwords.  From time to time thereafter,
DTFC will keep all information relating to its identification number and
passwords strictly confidential and will be responsible for the maintenance of
adequate security over its customer identification number and passwords.  For
security purposes, DTFC should change its passwords frequently (at least once a
year).

         Instructions transmitted over Noteline Direct and received by you
pursuant to Section 3 hereof accompanied by DTFC's identification number and
the passwords, shall be deemed conclusive evidence that such instructions are
correct and complete and that the issuance or redemption of the Note(s)
directed thereby has been duly authorized by DTFC.

         SECTION 4.  Delivery of Commercial Paper Notes.  No Certificated Note
shall be delivered by you to any Dealer or the applicable investor except
against receipt therefor.  A Certificated Note shall be deemed delivered
against receipt for purposes of this Section 4 if the





                                      -7-
<PAGE>   10
net proceeds of such Certificated Note are received by you in immediately
available funds at the time of your delivery of such Certificated Note to any
Dealer or the applicable Holder or if, at the time you deliver such
Certificated Note to such Dealer or such Holder you receive such Dealer's
receipt for the delivery in customary form.  In accordance with the custom in
the commercial paper market, delivery of such receipt shall obligate such
Dealer to deliver or cause to be delivered to you the purchase price of such
Certificated Notes in immediately available funds prior to your close of
business on such day.  Should you deliver any Certificated Notes against
receipt as provided in the second sentence of this Section 4 you shall have no
responsibility or liability for the credit risks involved in your delivery of
such Certificated Notes to those persons who shall be designated by an
Authorized Representative or for the failure of such persons to effectuate
payment therefor as herein contemplated.  It is understood that, as a matter of
bookkeeping convenience, the Depositary may credit the Commercial Paper Account
with the proceeds of Commercial Paper Notes prior to its actual receipt of
final payment therefor and that such bookkeeping credits may be reflected on
the Depositary's books, and otherwise, as "immediately available funds" or
"same day funds" or by some other similar characterization.  Notwithstanding
any such credit or characterization, all such credits shall be conditioned upon
the Depositary's receipt of final payment and may be reversed by the Depositary
to the extent that such final payment is not received.  DTFC agrees to
indemnify and hold the Depositary (which, for purposes of this sentence shall
include its directors, officers, employees and agents) harmless from any loss
which the Depositary may suffer and any expense (including the reasonable fees
and expenses of counsel) which the Depositary may incur as a result of the
failure of any purchaser to remit payment in full for any Commercial Paper
Notes (other than any loss or expense resulting from the gross negligence or
willful misconduct of the Depositary or any director, officer, employee or
agent thereof) and, without limiting the generality of the foregoing, DTFC
agrees that, immediately upon notification from the Depositary of failure of a
purchaser to remit payment, DTFC shall reimburse the Depositary in immediately
available funds any amount credited to DTFC in anticipation of receipt of such
payment plus any applicable overdraft fees and interest thereon for each day
such proceeds remain unreimbursed.  The overdraft charges and rate of interest
payable by DTFC to the Depositary shall be that provided for either (i) under
arrangements with respect to overdraft advances in effect at the time between
DTFC and the Depositary or (ii) if no such arrangements are then in effect, in
the Depositary's standard fee schedule for overdrafts.

         For purposes of this Section 4, payment for any Commercial Paper Notes
shall not be irrevocable and final until the Depositary shall have received
from or on behalf of the account of the purchaser of such Commercial Paper
Notes immediately available funds which under applicable law and rule are
irreversible, which are not subject to any security interest, levy or other
encumbrance enforceable against the Depositary or DTFC, and which are
specifically applicable or determined by the Depositary to be applicable to the
payment of such Commercial Paper Notes.  A debit by the Depositary to any
account of a person to whom or for whose account such Commercial Paper Notes
shall have been delivered shall not constitute final payment to the extent that
such debit creates an overdraft or does not otherwise result in the receipt by
the Depositary of immediately available, irreversible and unencumbered funds.

<PAGE>   11
         At the close of business on each Business Day on which Commercial
Paper Notes are issued or mature, you shall prepare a written statement
containing, or otherwise make electronically available, the following
information provided the Issuer delivers such request in writing: (i) the
aggregate face amount and issue price of all discount Commercial Paper Notes
issued on that Business Day and the principal amount and the interest rate of
all interest bearing Commercial Paper Notes issued on that Business Day, which
statement shall include the serial number, in the case of Certificated Notes,
or the CUSIP number, in the case of Book Entry CP Notes, issue date, maturity
date and face amount thereof; and (ii) the aggregate face amount and issue
price of all discount Commercial Paper Notes Outstanding and the aggregate
principal amount and the interest rate of all interest bearing Commercial Paper
Notes Outstanding at the close of business on such day.  You shall furnish such
information electronically or otherwise to DTFC, the Liquidity Agent and the
Collateral Agent on that day and at such other times as DTFC, the Liquidity
Agent or the Collateral Agent may from time to time reasonably request.  To the
extent that a written statement is the method of providing information, a copy
of each statement referred to above and each Certificated Note issued shall be
sent by you by either telecopy or overnight delivery service to DTFC, the
Liquidity Agent and the Collateral Agent at their addresses specified herein,
no later than the following Business Day.

         SECTION 5.  Payment of Commercial Paper Notes at Maturity.  (a)  Each
matured Commercial Paper Note presented to you for payment on any Business Day
prior to the standard window closing time (as established by the rules of the
New York Clearing House Association in effect from time to time) on such
Business Day, shall be paid the same day in accordance with the provisions of
paragraph (b) of this Section 5.  Each matured Commercial Paper Note presented
to you for payment on any Business Day after such time shall be paid on the
next succeeding Business Day in accordance with the provisions of paragraphs
(b) and (c) of this Section 5.

         (b)  You shall pay each matured Commercial Paper Note presented to you
for payment prior to the close of business on any Business Day from funds
available for such payment in the Commercial Paper Account (including funds
from Commercial Paper Notes issued or to be issued on that day).  If on any
given day on which a Commercial Paper Note is scheduled to mature by its terms,
upon receiving notice from the Dealers by 12:00 p.m. (New York City time) on
such day specifying the amount of Commercial Paper Notes placed by such Dealers
by that time on such day, and upon DTFC's determining that a Commercial Paper
Deficit exists, DTFC shall give notice thereof to the Collateral Agent, not
later than 12:15 p.m. (New York City time) on such day, and DTFC shall instruct
the Collateral Agent to deliver a Borrowing Request to the Liquidity Agent for
a Borrowing consisting of Refunding Advances, not later than 12:30 p.m. (New
York City time) on the date of a proposed Borrowing, irrevocably requesting
that a Borrowing be made in an aggregate principal amount (subject to the
immediately following sentence) equal to the excess of (i) the Commercial Paper
Deficit over (ii) the sum of the aggregate amount, if any, applied or to be
applied on such Business Day to the Commercial Paper Deficit from amounts
available therefor in the Collateral Account or the Series 1998-1 Collection
Account and the Termination Advance Account that are designated for payment of





                                      -9-
<PAGE>   12
maturing Commercial Paper Notes.  In accordance with and subject to the terms
of the Liquidity Agreement, the proceeds of any Refunding Advances (and/or any
Swing Line Advances) shall be remitted to the Commercial Paper Account not
later than 3:00 p.m. (New York City time) on the date of the requested
Borrowing.  You shall apply the proceeds of any Refunding Advances and any
Swing Line Advances obtained by you first to reimburse yourself for any
advances made by you on any matured Commercial Paper Note and second to the
payment of the Commercial Paper Notes in respect of which the Refunding
Advances and Swing Line Advances were obtained.

         (c)     If on any given day on which a Commercial Paper Note is
scheduled to mature by its terms (after giving effect to funds deposited in the
Commercial Paper Account pursuant to clause (b) above), a Commercial Paper
Deficit exists, and the Aggregate Liquidity Commitment shall be fully drawn
under the Liquidity Agreement, or is unavailable for reasons other than a
failure to satisfy conditions precedent for such drawing, (i) if the  Series
1998-1 Letter of Credit has not been terminated and LOC Termination
Disbursements have not been made, you are hereby authorized and directed to
notify the Collateral Agent to cause the Enhancement Agent to request LOC
Liquidity Disbursements in an amount equal to the Commercial Paper Deficit, as
it may be reduced after giving effect to funds received pursuant to clause (b)
above, (up to the Series 1998-1 Letter of Credit Amount) in accordance with the
provisions of the Collateral Agreement and (ii) if the Series 1998-1 Letter of
Credit has been terminated and LOC Termination Disbursements have been made,
then you are hereby authorized and directed to notify the Collateral Agent of
the existence and amount of the Commercial Paper Deficit, as so reduced, and to
instruct the Collateral Agent to cause the Enhancement Agent to withdraw an
amount equal to the Commercial Paper Deficit (up to the amount then on deposit
in the Series 1998-1 Cash Collateral Account) from the Series 1998-1 Cash
Collateral Account in accordance with the provisions of the Collateral
Agreement and deposit into the Commercial Paper Account such LOC Liquidity
Disbursement or such withdrawal from the Series 1998-1 Cash Collateral Account.
If a Commercial Paper Deficit continues to exist you shall cease paying matured
and maturing Commercial Paper until such time as the Collateral Agent shall
instruct you otherwise; it being understood that the purpose of such delay is
to permit an equitable distribution of funds allocated to the Holders pursuant
to the Collateral Agreement to be made pro rata according to the face amount of
all Commercial Paper Notes Outstanding (as may be adjusted as determined by the
Collateral Agent to compensate Holders for accrued interest to reflect delay in
payment) rather than first to the earliest maturing Commercial Paper Notes.  In
accordance and subject to the terms of the Series 1998-1 Letter of Credit, the
proceeds of such LOC Liquidity Disbursement or any such withdrawal from the
Series 1998-1 Cash Collateral Account shall be remitted into the Commercial
Paper Account not later than 4:00 p.m. (New York City time) on the date of the
requested drawing.  You shall apply the proceeds of any LOC Liquidity
Disbursement or any such withdrawal from the Series 1998-1 Cash Collateral
Account obtained by you first, to reimburse yourself for any advances made by
you on any matured Commercial Paper Note and second, to the payment of the
Commercial Paper Notes in respect of which LOC Liquidity Disbursements were
obtained.





                                      -10-
<PAGE>   13
         If at the time any Commercial Paper Note is presented to you for
payment there are insufficient funds on deposit and available in the Commercial
Paper Account (after giving effect to transfers thereto, if any, from the
Collateral Account or the Series 1998-1 Collection Account and from the
Liquidity Lenders in the form of Refunding Advances and/or Swing Line Advances
or from the Credit Enhancer in the form of LOC Liquidity Disbursements in
accordance with paragraph (b) or (c) of this Section 5) to pay such Commercial
Paper Note in full, you shall be entitled, but not required, to pay such
Commercial Paper Note before your close of business that day and you shall
thereupon be deemed and treated as the holder of such Commercial Paper Note and
shall be entitled to receive payment for such Commercial Paper Note (from the
proceeds of Refunding Advances, Swing Line Advances or LOC Liquidity
Disbursements, as the case may be, or from any other source available in
accordance with the Collateral Agreement for the payment of Commercial Paper
Notes).  DTFC shall pay you interest, upon your demand, on the amount paid by
you to the holder of such Commercial Paper Note at a rate per annum equal to
your corporate base rate in effect from time to time during the period from but
excluding the date of payment made by you to and including the day you are
reimbursed for such amount.  Unless you are reimbursed for such amount by DTFC
prior to your making demand for payment of such Commercial Paper Note, you
shall promptly make demand for payment of such Commercial Paper Note.

         (d)  DTFC hereby agrees to advise the Depositary by 9:30 a.m. (New
York City time) on each Business Day on which Commercial Paper Notes are
maturing of the aggregate amount of new Commercial Paper Notes, if any,
anticipated to be placed by the Dealers.  To the extent that the Depositary
determines that a Commercial Paper Deficit exists between such aggregate amount
and the aggregate amount of new Commercial Paper Notes that are actually placed
by the Dealers as of 12:00 noon (New York City time) on such Business Day as
reported to the Depositary, the Depositary will use its best efforts to contact
DTFC with the amount of such Commercial Paper Deficit so as to determine
whether a Commercial Paper Deficit exists.

         (e)  Certificated Notes paid in full by you shall be canceled and held
by you in safekeeping for disposition in accordance with written instructions
to you by DTFC.  Unless DTFC instructs you otherwise, you shall dispose of such
Certificated Notes in accordance with your usual procedure.

         SECTION 6.  Book Entry Commercial Paper Notes.  (a)  DTFC may elect to
make the Commercial Paper Notes eligible for the book entry commercial paper
program of DTC, in which case (i) DTFC will instruct the Depositary in writing
to issue book entry Commercial Paper Notes ("Book Entry CP Notes") through DTC
instead of, or in addition to, issuing certificated Commercial Paper Notes as
hereinbefore provided, (ii) the Depositary will prepare for execution by DTFC
and the Depositary DTC's current form Letter of Representations (the "Letter"),
a copy of which is attached hereto as Exhibit D, (iii) DTFC will provide to the
Depositary for submission with the Letter a copy of the information memorandum
for DTFC's commercial paper program under which the Commercial Paper Notes are
issued by the Depositary pursuant to this Agreement and (iv) DTFC will deliver
the Letter to DTC's Legal





                                      -11-
<PAGE>   14
Department and will return to the Depositary a copy of the Letter after it has
been received and accepted by DTC.  The Depositary is authorized and directed
to issue and settle through DTC Book Entry CP Notes in accordance with the
applicable rules and procedures established by DTC and the Depositary for the
issuance and settlement of book entry notes upon receipt by the Depositary of
written instructions pursuant to clause (i) of the immediately preceding
sentence.  DTC's procedures with respect to the issuance of book entry notes
(the "Book Entry Procedures"), among other things, currently provide that
issuance of Book Entry CP Notes with a maturity date on a holiday on which DTC
is scheduled to be closed for settlement services are not acceptable for
deposit into DTC's CP Program.  In the event there is any delay in the issuance
of Book Entry CP Notes resulting from DTFC's instructions to the Depositary
providing for the issuance of Book Entry CP Notes to mature on DTC holidays,
the Depositary shall not be liable to DTFC, DTC or any beneficial owner of a
Book Entry CP Note.  Each Book Entry CP Note issued and distributed through DTC
upon the instruction of a Designated Person from an Authorized Representative
shall constitute DTFC's representation and warranty that such Book Entry CP
Note is a legal, valid and binding obligation of DTFC.

         (b)  Once the Commercial Paper Notes have been accepted by DTC for
DTC's commercial paper program and prior to the issuance and distribution of
any Book Entry CP Notes, DTFC will deliver (i) to the Depositary, as custodian
for DTC, the Master Note (the "Master Note") with respect to Book Entry CP
Notes issued at a discount from face value to be paid at maturity and with
respect to Book Entry CP Notes issued in interest bearing form (in the form of
Exhibit E hereto), duly executed on behalf of DTFC by the manual or facsimile
signature of an Authorized Signatory to evidence Book Entry CP Notes to be
issued and distributed through DTC by the Depositary on behalf of DTFC (and the
obligation of DTFC to provide for payment of such Book Entry CP Notes at their
respective maturities) and (ii) to the Depositary, copies of all agreements
entered into by DTFC required by DTC for participation in DTC's book entry
commercial paper program.  The Depositary shall maintain a record of each
change in the face amount of Outstanding Book Entry CP Notes or, in the case of
interest bearing Book Entry CP Notes the principal amount and the interest rate
thereon represented thereby and the maturity dates thereof.

         (c)  In accordance with DTC's book entry commercial paper program, the
Depositary shall obtain from the CUSIP Service Bureau a written list of CUSIP
numbers for the Book Entry CP Notes that will be issued through DTC as provided
in the Letter, and the Depositary shall deliver such list to DTC.  The
Depositary shall instruct the CUSIP Service Bureau to bill DTFC for the fee or
fees payable to CUSIP Service Bureau for such list of CUSIP numbers for book
entry Commercial Paper Notes.  The CUSIP numbers, as required by DTC's
commercial paper program, will be assigned to DTFC's Book Entry CP Notes upon
issuance and used to identify DTFC's Outstanding Book Entry CP Notes in DTC's
book entry system.

         (d)  On and after the date when the Commercial Paper Notes become
eligible for DTC's book entry commercial paper program, the Depositary shall
execute all instructions from DTFC to issue Commercial Paper Notes by, subject
to the provisions of Section 3 of this Agreement,





                                      -12-
<PAGE>   15
issuing and delivering only Book Entry CP Notes through DTC, except where the
Depositary has been specifically instructed in writing by DTFC to complete and
deliver one or more Certificated Notes.

         (e)  In the event and on each occasion that DTFC agrees with a Holder
that holds Book Entry CP Notes (a "Book Entry CP Holder") to prepay such Book
Entry CP Holder's Book Entry CP Notes on deposit with DTC prior to the
scheduled maturity of such Book Entry CP Notes, DTFC shall make arrangements
with such Book Entry CP Holder and the Depositary for the delivery through the
DTC system by the DTC participant holding such Commercial Paper Notes to the
Depositary's designated account at DTC for payment.

         (f)  DTFC may for any reason discontinue its participation in DTC's
book entry commercial paper program with respect to the Commercial Paper Notes
at any time upon not less than ten days prior written notice to the Depositary
(with copies of such notice to the Dealers).  In the event DTFC shall
discontinue its participation in DTC's book entry commercial paper program, or
DTC shall discontinue its services with respect to the Book Entry CP Notes,
DTFC and the Depositary shall cooperate in taking appropriate action, including
without limitation, if necessary, delivery of one or more Certificated Notes to
any DTC participant having Book Entry CP Notes credited to its DTC account.  In
the event of such discontinuance of DTFC's participation in DTC's commercial
paper program as herein described, and upon delivery of Certificated Notes in
respect of all Book Entry CP Notes represented by the Master Note, the
Depositary shall destroy such Master Note and provide DTFC with a duly executed
certificate of destruction with respect to such Master Note.  Upon written
notice by DTFC to the Depositary of the discontinuance of DTFC's participation
in DTC's book entry program with respect to the Commercial Paper Notes in
respect of all Book Entry CP Notes represented by the Master Note, the
Depositary shall destroy such Master Note and provide DTFC with a duly executed
certificate of destruction with respect to such Master Note.  Notice by DTFC to
the Depositary of the discontinuance of DTFC's participation in DTC's book
entry program with respect to the Commercial Paper Notes shall not constitute
notice of termination of the Depositary's duties as issuing and paying agent
for Certificated Notes under this Agreement.

         (g)  All references in this Agreement to "Commercial Paper Notes"
shall apply to and shall include any Book Entry CP Notes issued hereunder by
DTFC.  Any reference in this Agreement to authentication, completion and
delivery of the Commercial Paper Notes shall, in the context of Book Entry CP
Notes, be deemed to mean issuance of Commercial Paper Notes in accordance with
DTC's and the Depositary's rules and procedures with respect to the Book Entry
CP Notes and any reference to presentation of Commercial Paper Notes for
payment shall, in the context of Book Entry CP Notes, be deemed to mean the
procedure undertaken by DTC to make a demand for payment from DTFC (through the
Depositary) of matured Book Entry CP Notes.  References in this Agreement to
"Holders" of the Commercial Paper Notes shall, in the context of Book Entry CP
Notes, refer to the beneficial owners of such Book Entry CP Notes, except that
in the case of payment of Book Entry CP Notes by the Depositary, the term
"Holder" shall be deemed to refer to Cede & Co.  Upon payment of all
Outstanding Book Entry CP Notes





                                      -13-

represented by a Master Note, and upon request by DTFC, the Depositary shall
destroy such Master Note, and provide DTFC with a duly executed certificate of
destruction with respect to such Master Note.

         SECTION 7.  Inspection of Documents by Commercial Paper Note Holders.
You shall keep a fully executed or conformed copy of the Liquidity Agreement,
the Collateral Agreement and this Agreement (together with all amendments,
modifications, supplements, waivers and consents made or given with respect
thereto which have been delivered to you by the Issuer), on file at your
address set forth in Section 12 hereof.  DTFC agrees to provide to you a copy
of all such documents and any amendments thereto promptly following their
execution.  You shall permit reasonable inspection to be made of such documents
during normal business hours by the Holder of any Commercial Paper Note or by
any officer, employee or agent of such Holder, provided that the person
purporting to be such Holder establishes to your satisfaction that he is in
fact such Holder of such Commercial Paper Note and, in cases where inspection
is sought to be made by a person purporting to be an officer, employee or agent
of such Holder, that such person submits evidence satisfactory to you of his
authority to make such inspection on behalf of the Holder of such Commercial
Paper Note.

         SECTION 8.  Expenses and Indemnity.  DTFC agrees:

                 (a)  to pay to you from time to time reasonable compensation
         for all services rendered by you hereunder, which are subject to
         change as circumstances may warrant as set forth in Exhibit G hereto,
         including for the issuance of Book Entry CP Notes through DTC, and to
         reimburse you for expenses, disbursements and advances (if any), in
         each case as mutually agreed upon;

                 (b)  to indemnify you (which for purposes of this Section 8
         shall include your directors, officers, employees and agents) for, and
         hold you harmless from and against, any and all losses (except your
         loss of profit), liabilities (including liabilities for penalties),
         actions, suits, judgments, demands, damages, reasonable out-of-pocket
         costs and expenses (including, without limitation, interest and
         reasonable attorneys' fees and disbursements, but excluding costs and
         expenses attributable solely to administrative overhead) arising out
         of, in connection with, or resulting from the review, execution and
         delivery of this Agreement or any amendment hereto, or in connection
         with, the exercise of your rights and/or the performance of your
         duties, by you or by your directors, officers, agents and employees,
         hereunder; provided, however, that DTFC shall not be liable to
         indemnify you for, or hold you harmless from, damage, cost and expense
         resulting from or attributable to your gross negligence or willful
         misconduct or that of your officers, employees or agents.  The
         foregoing indemnity will survive the termination or expiration of this
         Agreement and your resignation or removal as Depositary and issuing
         and paying agent, and includes, but is not limited to, any action
         taken or omitted to be taken by you upon telephonic, electronic or
         written instructions (authorized herein) received by you from, or
         believed by you in good faith to have been given by, the proper person
         or





                                      -14-

         persons; provided further, that any claims arising hereunder shall be
         limited by the provisions of Section 20 hereof.

         SECTION 9.  Representations and Warranties.  In addition to any other
representations and warranties on the part of DTFC contained herein, DTFC
hereby represents and warrants to you that its entry into this Agreement, and
your appointment by DTFC as depositary and issuing and paying agent and, in
certain circumstances, as agent with respect to the Commercial Paper Notes,
have been duly authorized by all necessary corporate action on the part of DTFC
and will not result in any violation, breach or contravention of any law, rule,
regulation, order, contract or agreement binding upon DTFC which has a Material
Adverse Effect, or may in the future have a Material Adverse Effect on, the
business, financial condition or operations of DTFC or the performance by DTFC
of its obligations under any of the CP Program Documents to which it is a
party.  In addition, DTFC represents and warrants, and each instruction to
issue Commercial Paper Notes will constitute a representation and warranty,
that the issuance of the Commercial Paper Notes, including, if the Commercial
Paper Notes become eligible for deposit as book entry only in DTC's commercial
paper program, the issuance of Book Entry CP Notes and the execution of any
instruments or documents required by DTC in connection therewith, has been duly
and validly authorized by all necessary corporate action, and that the
Commercial Paper Notes, when completed, countersigned and delivered pursuant
hereto, will constitute DTFC's legal, valid and binding obligation enforceable
against DTFC in accordance with their terms, are not required to be registered
under the Securities Act of 1933, as amended, and from applicable state
securities laws and will be in conformity with the terms of the Liquidity
Agreement.

         SECTION 10.  Term and Termination.  (a)  The term of this Agreement
(except for the provisions of Sections 8, 20 and 21 which shall survive
indefinitely and the provisions of Section 18, which shall survive for the
period set forth therein) shall extend from the date hereof and shall end on
the earliest of:

                 (i)  the date on which all Commercial Paper Notes have been
         repaid, the Aggregate Liquidity Commitment has terminated and the
         Series 1998-1 Letter of Credit Expiration Date has occurred, subject
         to the conditions set forth in paragraph (d) of this Section 10; and

                 (ii)  the date of termination specified in any termination
         notice given pursuant to paragraph (b) of this Section 10.

         Any Commercial Paper Notes Outstanding on the date of any termination
of this Agreement pursuant to paragraphs (a) or (b) of this Section 10 shall
nevertheless remain valid obligations of DTFC, and the provisions of this
Agreement shall continue to be applicable with respect to the payment of such
Commercial Paper Notes to the same extent as if this Agreement had not
terminated.





                                      -15-
<PAGE>   18
         (b)  Either you or DTFC may terminate this Agreement and the authority
granted to you herein, at any time upon not less than thirty Business Days'
prior written notice given to the other parties hereto specifying the
termination date hereof (which shall not occur on the date of maturity of any
Commercial Paper Notes nor the Business Day next preceding any such date).
Notwithstanding the preceding sentence, no termination of this Agreement shall
take effect until a successor to the Depositary has been duly appointed, unless
all outstanding Commercial Paper Notes have been paid in full and no amounts
are due to Commercial Paper holders.  You may petition a court of competent
jurisdiction if no such appointment is made within 30 Business Days of your
termination notice.  No successor to the Depositary may be appointed, however,
if such appointment shall result in the withdrawal or reduction of any rating
assigned to the Commercial Paper Notes.  Upon the termination of this Agreement
under paragraph (a) of this Section or this paragraph (b), you shall promptly
deliver to DTFC or your successor, if one is appointed, all Commercial Paper
Notes (including any Master Note) then held by you hereunder for DTFC's account
for safekeeping, against receipt by DTFC or such successor, and shall cause to
be deposited in the Collateral Account, upon advice to DTFC, the Liquidity
Agent and the Collateral Agent, all funds, if any, then on deposit in, or
otherwise to the credit of, the Commercial Paper Account.

         (c)  No Commercial Paper Notes shall be delivered to you by DTFC for
safekeeping or issuance hereunder nor shall any Certificated Notes be
authenticated or delivered to any Dealer or any applicable holder or any Book
Entry Issuance Instruction be issued by you upon the termination of this
Agreement and the authority granted to you herein.

         (d)  Notwithstanding any termination of this Agreement, the Depositary
(or the successor to the Depositary if one has been appointed) shall maintain
the Commercial Paper Account until the earlier of the first anniversary of the
date of termination of this Agreement and the date on which the Commercial
Paper Notes Outstanding have been paid in full and apply any amounts in the
Commercial Paper Account to repay Commercial Paper Notes as they mature.
Pending disbursement of such amounts to repay maturing Commercial Paper Notes,
the Depositary or the Collateral Agent, as the case may be, shall invest such
amounts in Eligible Investments designated in writing by DTFC which mature not
later than the anticipated date or dates on which Commercial Paper Notes
mature, such written designation to certify that the requested investment
constitutes an Eligible Investment and matures at the time required by this
sentence.  Any investment earnings on Eligible  Investments shall be released
to DTFC after payment in full of all Commercial Paper Notes Outstanding.

         SECTION 11.  Amendments and Modifications.  (a)  No amendment,
modification, termination or waiver of any provision of this Agreement shall be
effective unless (i) the same shall be in writing and signed by all of the
parties hereto and consented to in writing by the Dealers, the Liquidity Agent
on behalf of the Majority Banks and the Collateral Agent, and (ii) S&P, Moody's
and DCR have confirmed in writing that their respective ratings on the
Commercial Paper Notes will not be lowered or withdrawn as a result of any such
amendment, modification, termination or waiver.  No such amendment,
modification, termination or waiver





                                      -16-
<PAGE>   19
shall, as evidenced by an opinion of counsel delivered to the Depositary by the
Issuer upon which it may conclusively rely, adversely affect the rights of the
Holder or Holders of any Commercial Paper Notes Outstanding at the time of such
amendment, modification, termination or waiver unless consented to in writing
by such Holder or Holders.

         Notwithstanding the foregoing provisions of this Section 11(a), the
Dealers, the Liquidity Agent and the Collateral Agent may with the written
consent of the Depositary, at any time and from time to time, without the
consent of the Majority Banks, enter into any amendment, supplement or other
modification to this Agreement to cure any apparent ambiguity or to correct or
supplement any other provision herein; provided, however, that (i) any such
action shall not have a material adverse effect as evidenced by an opinion of
counsel delivered to the Depositary by the Issuer on the interests of the
Liquidity Lenders and (ii) a copy of such amendment, supplement or other
modification is furnished to each Liquidity Lender in accordance with the
notice provisions of the Liquidity Agreement not later than ten days prior to
the execution thereof by the parties hereto.

         (b)  Contemporaneously with any amendment, modification, termination
or waiver of any provision of the Liquidity Agreement, the Collateral Agreement
or any other CP Program Document, DTFC shall give notice to you summarizing
such action and shall furnish you with a fully executed and conformed copy of
such amendment, modification, waiver or consent.  No amendment of any of the
foregoing agreements which could reasonably be expected to have a material
adverse effect on your rights, duties or powers hereunder shall be effective
against you without your written consent.

         SECTION 12.  Notices.  Except where telephonic instructions or notices
are authorized herein to be given, all notices, demands, instructions and other
communications required or permitted to be given to any party hereunder shall
be in writing and addressed, delivered or transmitted to such party at its
address or facsimile number set forth below, or at any other address or
facsimile number, as the case may be, as such party may notify the other
parties hereto in accordance with the provisions of this Section 12.  Any
notice, if mailed and properly addressed with postage prepaid or if properly
addressed and sent by pre-paid courier service, shall be deemed given when
received; any notice, if transmitted by facsimile, shall be deemed given when
transmitted upon receipt of electronic confirmation of transmission.

<PAGE>   23
                 (a) Delivery by DTFC to the Depositary of execution copies of
         this Agreement, the Liquidity Agreement, the Collateral Agreement and
         the Series 1998-1 Letter of Credit.

                 (b) Delivery by DTFC to the Depositary of (i) a legal opinion
         on the enforceability of this Agreement, the enforceability of the
         Commercial Paper Notes when issued, the enforceability of the
         Collateral Agreement under New York State law, the exemption of the
         Commercial Paper Notes from registration under the Securities Act of
         1933 and the exemption of DTFC from the Investment Company Act of 1940
         reporting requirements and (ii) its incumbency certificate in the form
         of Exhibit B.

         SECTION 17.  Headings.  Section headings used in this Agreement are
for convenience only and shall not affect the construction of this Agreement.

         SECTION 18.  No Petition.  You, in your capacity as Depositary hereby
covenant and agree that, prior to the date which is one year and one day after
the payment in full of all Commercial Paper Notes Outstanding, you will not
institute against, or join any other Person in instituting against, DTFC, any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
or other similar proceeding under the laws of the United States or any state of
the United States.  In the event that you take action in violation of this
Section 18, DTFC agrees, for the benefit of the Holders, that it shall file, an
answer with the bankruptcy court or otherwise properly contest the filing of
such a petition by you against DTFC or the commencement of such action and
raise the defense that you have agreed in writing not to take such action and
should be estopped and precluded therefrom and such other defenses, if any, as
its counsel advises that it may assert.  The provisions of this Section 18
shall survive the termination of this Agreement, and your resignation or
removal as Depositary and issuing and paying agent.

         SECTION 19.  Duties and Responsibilities.  It is understood that you
are acting as agent of DTFC.  Neither you nor any of your officers, directors,
employees or agents shall be liable for any action taken or omitted to be taken
by you or them hereunder except for acts of gross negligence or willful
misconduct by your officers, employees or agents.  Neither the Depositary nor
its officers or employees shall be required to ascertain whether any issuance
or sale of Commercial Paper Notes (or any amendment or termination of this
Agreement) has been duly authorized or is in compliance with any other
agreement to which DTFC is a party (whether or not the Depositary is a party to
such other agreement).  You undertake to perform such duties and only such
duties as are set forth in this Agreement and no implied covenants shall be
read into this Agreement against you and you make no representations or
warranties with respect to the valuation or adequacy of the Depositary's
collateral.  The Depositary shall also not be liable for any action taken, or
any failure to take any action in connection with this Agreement or the
services provided hereunder or otherwise to fulfill its obligations in
connection with this Agreement, in the event and to the extent that the taking
of such action or such failure arises out of or is caused by mechanical
breakdown, computer or system failure or other failure of equipment, failure or
malfunctioning of any communications media for whatever reason, or any





                                      -21-
<PAGE>   24
other cause outside of the control of the Depositary, provided that the
Depositary undertakes to use reasonable efforts to cure any such failure or
breakdown of the Depositary's equipment.  It is understood by DTFC that
provision of services under this Agreement is dependent upon the availability
to the Depositary and DTFC of telecommunication facilities provided by third
party vendors and that the Depositary cannot warrant such availability.

         You shall incur no liability in acting within the scope of this
Agreement on any notice or instruction, telephonic or written, given hereunder
which a Designated Person believes in good faith to have been given by an
Authorized Representative or by the Liquidity Agent or the Collateral Agent;
nor shall you in so acting assume or be deemed to have assumed any
responsibility for the propriety of any transaction effected by you under, or
the compliance of any such transaction with the Liquidity Agreement or any CP
Program Document.  Your countersignature of any Commercial Paper Note shall be
for authentication purposes only and neither you nor any person countersigning
on your behalf shall have any liability on any Commercial Paper Note.

         You may rely and shall be protected in acting or refraining from
acting upon any communication authorized by this Agreement and upon any written
instruction, notice, request, direction, consent, report, certificate,
Commercial Paper Note or other instrument, paper or document believed by you to
be genuine.  You shall not be liable for acting upon any telephone
communication authorized by this Agreement which you believe in good faith to
have been given by DTFC or any authorized party hereunder.  You may record
telephone communications with DTFC or any authorized party hereunder.

         Anything in this Agreement to the contrary notwithstanding, in no
event shall you, or any of your directors, officers, employees or agents, be
liable under this Agreement to DTFC or any third party for indirect, special,
punitive, incidental or consequential loss or damage of any kind whatsoever,
including, but not limited to, lost profits, whether or not the likelihood of
such loss or damage was known to you, or any such director, officer, employee
or agent. In no event shall the Depositary be considered negligent in
consequence of complying with DTC's rules, regulations and procedures.

         You may consult with counsel and the advice of such counsel shall be
full and complete authorization and protection in respect of any action taken,
offered or omitted by you hereunder in good faith and in reliance thereon.

         No prior action or course of dealing on your part with respect to
advances of the purchase price or payments of matured commercial paper shall
give rise to any claim or cause of action by the Issuer, any holder, or any
other party against you in the event that you refuse to pay or settle any
Commercial Paper Notes for which the Issuer has not timely provided funds as
required by this Agreement.

         You in your individual or any other capacity, may become the owner or
pledgee of Commercial Paper Notes or a participant in the credit provided under
the Liquidity Agreement or the Series 1998-1 Letter of Credit and may otherwise
transact banking or trust business with any of the parties with the same rights
as you would have if you were not acting hereunder.

         Except as otherwise expressly provided herein, whenever, in the
administration of this Agreement, you shall deem it necessary that a matter be
proved or established prior to taking, suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may be deemed to be conclusively proved and
established by a certificate of an Authorized Representative, and such
certificate shall be full warranty to you for any action taken, suffered or
omitted under the provisions of this Agreement upon the faith thereof.

         Except as otherwise provided herein, the Depositary may execute any of
the powers hereunder or perform any duties hereunder either directly or by or
through agents, including, without limitation, the Sub-Agent, or attorneys;
provided, however, that the Depositary shall not be responsible for the acts of
DTC but shall be responsible only for the selection of other agents with due
care.  DTFC hereby acknowledges the interest of DTC in the Commercial Paper
Notes and Certificated Notes.  The Depositary shall be under no liability for
interest on any moneys received by the Depositary hereunder except as the
Depositary may agree with DTFC to pay thereon.

         SECTION 20.  No Recourse.  The obligations of DTFC under this
Agreement are solely the corporate obligations of DTFC.  No recourse shall be
had for the payment of any amount owing in respect to Section 8 hereof or for
the payment of any fee hereunder or any other obligation or claim arising out
of or based upon this Agreement against any Dealer or against any shareholder,
employee, officer, director or incorporator of DTFC. For purposes of this
Section 20, the term "Dealer" shall mean and include all Affiliates thereof and
any employee, officer, director, incorporator, shareholder, affiliate or
beneficial owner of any of them; provided, however, that neither the Depositary
nor DTFC shall be considered to be an Affiliate of any Dealer for purposes of
this Section 20.

         SECTION 21.  Limited Recourse to DTFC.  Notwithstanding any other
provision of this Agreement, the Depositary agrees that the obligations of DTFC
to the Depositary hereunder shall be payable in the order and priority set
forth in Section 2.01 and 5.02(b), as applicable, of the Collateral Agreement.
Such obligations shall be due and payable to the extent that DTFC's assets are
sufficient to pay such obligations.  No recourse shall be had for the payment
of any amount owing hereunder or for the payment of any fee hereunder or any
other obligation or claim arising out of or based upon this Agreement against
any stockholder, employee, officer, director or incorporator of DTFC; provided,
however, that the foregoing shall not relieve any such person or entity from
any liability they might otherwise have as a result of fraudulent actions or
omissions taken by them.  No claims of the Depositary (whether under the cited
provision or





                                      -23-
<PAGE>   26
otherwise) arising under or in connection with this Depositary Agreement are
intended to be impaired or waived by this Section 21.

         SECTION 22.  Merger or Consolidation.  Any corporation or other entity
into which the Depositary may be merged or consolidated, or any corporation or
other entity resulting from any merger, conversion or consolidation to which
the Depositary shall be a party, or any Person or entity succeeding to the
corporate trust or agency business of the Depositary, shall be the successor of
the Depositary hereunder (without relieving the Depositary of its
responsibilities hereunder if it survives such merger, conversion,
consolidation or succession) without the execution or filing of any paper or
any further act on the part of any party hereto, anything to the contrary
notwithstanding; provided, however, that (a) upon the request of DTFC, the
Collateral Agent or the Liquidity Agent, such corporation, entity or successor
shall execute an assumption agreement providing for the assumption by such
corporation, entity or successor of the rights and obligations of the
Depositary in a form reasonably satisfactory to DTFC, the Collateral Agent and
the Liquidity Agent and (b) the Depositary shall give the Rating Agencies prior
written notice of such merger, conversion, consolidation or succession.

         SECTION 23.  Amortization Event.  If the Depositary shall have been
notified by DTFC, the Liquidity Agent, any Liquidity Lender or the Collateral
Agent that an Amortization Event shall have occurred, the Depositary shall
notify the Liquidity Agent and the Collateral Agent in writing as soon as
possible upon payment in full of all Commercial Paper Notes Outstanding or the
receipt of funds in the amount required to pay all Commercial Paper Notes
Outstanding upon maturity.

         SECTION 24.  Entire Agreement.  This Agreement together with the
exhibits attached hereto, constitutes the entire understanding among the
parties hereto with respect to the Depositary. This Agreement is solely for the
benefit of the parties hereto and no other person shall acquire or have any
right under or by virtue hereof.

         SECTION 25.  Waiver of Set-Off.  The Depositary hereby waives and
relinquishes any right it has or may have to set-off or to exercise any
banker's lien or any right of attachment or garnishment with respect to any
funds at any time and from time to time on deposit in, or otherwise to the
credit of, any account and any claims of DTFC therein or with respect to any
right to payment from DTFC, it being understood, however, that nothing
contained in this Section 25 shall, or is intended to, derogate from the
assignment and security interest granted to the Collateral Agent under the
Collateral Agreement or impair any rights of the Holders, the Depositary or the
Collateral Agent thereunder.

         SECTION 26.  Additional Notice.  DTFC shall give prompt written notice
to each Rating Agency if it is required to make a payment hereunder to the
Depositary with respect to increased costs of the Depositary or indemnification
obligations to the Depositary.

deliver to you all documents you may reasonably request relating to corporate
existence and authority to enter into this Agreement, including, without
limitation, an opinion of counsel to that effect.

         SECTION 28.  Force Majeure. In no event shall you be liable for any
failure or delay in the performance of your obligations hereunder because of
circumstances beyond your control, including, but not limited to, acts of God,
flood, war (whether declared or undeclared), terrorism, fire, riot, strikes or
work stoppages for any reason, embargo, government action, including any laws,

equipment, or communications or computer facilities, and other causes beyond
your control whether or not of the same class or kind as specifically named
above.

unconditionally submits to the jurisdiction of the United States District Court
for the Southern District of New York and any New York State court located in
the Borough of Manhattan in New York City and of any appellate court from any
thereof for the purposes of any legal suit, action or proceeding arising out of
or relating to this Agreement (a "Proceeding"). Each party hereby irrevocably
agrees that all claims in respect of any Proceeding may be heard and determined
in such Federal or New York State court and irrevocably waives, to the fullest
extent it may effectively do so, any objection it may now or hereafter have to
the laying of venue of any Proceeding in any of the aforementioned courts and
the defense of an inconvenient forum to the maintenance of any Proceeding.

                                                     to the Depositary Agreement

                                Noteline Direct


         The Issuer is granted a personal, non-transferable and non-exclusive
right to use the instruction and reporting communication service Noteline
Direct ("Noteline Direct") to transmit through the Noteline Direct system
Instructions made pursuant to the Agreement.  The Issuer may, by separate
agreement between the Issuer and one or more of its commercial paper dealers or
sales agents (each an "Agent"), authorize the Agent (in each case other than
the Depositary) to directly access Noteline Direct for the purposes of
transmitting Instructions to the Depositary or obtaining reports with respect
to the obligations of the Issuer under the Agreement (the "Obligations").

         The Issuer acknowledges that (a) some or all of the services utilized
in connection with Noteline Direct are furnished by Digital Transactions Inc.
("DTI"), Dynamic Microprocessor Associates Inc. ("DMA") and Bankers Trust
Company, (b) Noteline Direct is provided to the Issuer "AS IS" without
warranties or representations of any kind whatsoever by DTI, DMA or the
Depositary, and (c) Noteline Direct is proprietary and confidential property
disclosed to the Issuer in confidence and only on the terms and conditions and
for purposes set forth in this Agreement.

         By this Agreement, the Issuer acquires no titles, ownership or
sublicensing rights whatsoever in Noteline Direct or in any trade secret,
trademark, copyright or patent of the Depositary, DTI, or DMA now or to become
applicable to Noteline Direct.  The Issuer may not transfer, sublicense,
assign, rent, lease, convey, modify, translate, convert to a programming
language, decompile, disassemble, recirculate, republish or redistribute
Noteline Direct for any purpose without the prior written consent of the
Depositary and, where necessary, DTI and DMA.

         In the event (a) any action is taken or threatened which may result in
a disclosure or transfer of Noteline Direct or any part thereof, other than as
authorized by this Agreement, or (b) the use of any trademark, trade name,
service mark service name, copyright or patent of the Depositary, DTI or DMA by
the Issuer amounts to unfair competition, or otherwise constitutes a possible
violation of any kind, then the Depositary and/or DTI and/or DMA shall have the
right to take any and all action deemed necessary to protect their rights in
Noteline Direct, and to avoid the substantial and irreparable damage which
would result from such disclosure, transfer or use, including the immediate
termination of the Issuer's right to use Noteline Direct.

         To permit the use of Noteline Direct to issue instructions and/or
obtain reports with respect to the obligation, the Depositary will supply the
Issuer with an identification number and initial passwords.  From time to time
thereafter, the Issuer may change its passwords directly


<PAGE>   40
through Noteline Direct.  The Issuer will keep all information relating to its
identification number and passwords strictly confidential and will be
responsible for the maintenance of adequate security over its customer
identification number and passwords.  For security purposes, the Issuer should
change its passwords frequently (at least one a year).

         Instructions transmitted over Noteline Direct and received by the
Depositary pursuant to the Agreement accompanied by the Issuer's identification
number and the passwords, shall be deemed conclusive evidence that such
Instructions are correct and complete and that the issuance or redemption of
the Obligation(s) directed thereby has been duly authorized by the Issuer.

Certificate") certifying as to the incumbency and specimen signatures of
officers of the Depositary (the "Depositary Agents") authorized to act, and to
give instructions and notices, on behalf of the Depositary hereunder.  Until
the Collateral Agent receives a subsequent Depositary Incumbency Certificate,
the Collateral Agent shall be entitled to rely on the last such Depositary

Covenants of DTFC.  DTFC hereby makes the following representations, warranties
and covenants to the Collateral Agent, the Depositary, the Liquidity Agent, the
Holders of the Commercial Paper Notes, the Liquidity Lenders and the Dealers:

                 (a)      All action necessary (including the filing of UCC-1
         financing statements, the delivery of the Series 1998-1 Notes to the
         Collateral Agent) to protect and perfect the Collateral Agent's
         security interest on behalf of the Secured Parties in the Assigned

         acquired or created and the Deposited Funds has been duly and
         effectively taken.





                                      -6-
<PAGE>   11
                 (b)      No security agreement, financing statement,
         equivalent security or lien instrument or continuation statement
         listing DTFC as debtor covering all or any part of the Assigned
         Collateral is on file or of record in any jurisdiction, except such as
         may have been filed, recorded or made by DTFC in favor of the
         Collateral Agent pursuant to this Collateral Agreement.

                 (c)      This Collateral Agreement creates a valid and
         continuing Lien on the Assigned Collateral in favor of the Collateral
         Agent on behalf of the Secured Parties, which Lien is prior to all
         other Liens, except for Permitted Liens, and is enforceable as such as
         against creditors of and purchasers from DTFC.  All action necessary
         or desirable to protect and perfect such prior security interest has
         been duly taken.

                 (d)      DTFC's principal place of business and chief
         executive office shall be at: 5330 East 31st Street, Tulsa, Oklahoma
         74135 and the place where its records concerning the Assigned
         Collateral are kept is at 5330 East 31st Street, Tulsa, Oklahoma
         74135. DTFC will not change its name or such principal place of
         business or chief executive office or remove such records without 30
         days prior written notice to the Collateral Agent.

                 (e)      At any time and from time to time, upon the written
         request of the Collateral Agent, and at the sole expense of DTFC, DTFC
         will promptly and duly execute and deliver any and all such further
         instruments and documents and take such further action as the
         Collateral Agent may reasonably deem necessary in obtaining the full
         benefits of this Collateral Agreement and of the rights and powers
         herein granted, including, without limitation, the filing of any
         financing or continuation statements under the Uniform Commercial Code
         in effect in any jurisdiction with respect to the liens and security
         interests granted hereby.  DTFC also hereby authorizes the Collateral
         Agent if directed by the secured Parties to file any such financing or
         continuation statement without the signature of DTFC to the extent
         permitted by applicable law.  If any amount payable under or in
         connection with any of the Assigned Collateral shall be or become
         evidenced by any promissory note, chattel paper or other instrument,
         such note, chattel paper or instrument shall be deemed to be held in
         trust and immediately pledged to the Collateral Agent hereunder, and
         shall, subject to the rights of any Person in whose favor a prior Lien
         has been perfected, be duly endorsed in a manner satisfactory to the
         Collateral Agent promptly.

                 (f)      DTFC will warrant and defend the Collateral Agent's
         right, title and interest in and to the Assigned Collateral and the
         income, distributions and proceeds thereof, for the benefit of the
         Secured Parties against the claims and demands of all Persons
         whomsoever.

                 (g)      All authorizations in this Collateral Agreement for
         the Collateral Agent to endorse checks, instruments and securities and
         to execute financing statements, continuation statements, security
         agreements and other instruments with respect to the Assigned
         Collateral are powers coupled with an interest and are irrevocable.

         SECTION 3.04.            Representations and Warranties of the
Collateral Agent.  The Collateral Agent hereby represents, warrants and
covenants to the Secured Parties that this Collateral Agreement has been duly
authorized, executed and delivered by the Collateral Agent and constitutes a
legal, valid and binding obligation of the Collateral Agent, enforceable
against the Collateral Agent in accordance with its terms, except as such
enforceability may be subject to bankruptcy or insolvency laws, creditors'
rights generally and general principles of equity.


                                  ARTICLE IV.

                                   ASSIGNMENT

         SECTION 4.01.            Assignment.  (a) In order to secure and
provide for the payment and repayment of the DTFC Obligations, DTFC hereby
pledges, assigns, conveys, delivers, transfers and sets over to the Collateral
Agent, for the ratable benefit of the Collateral Agent, the Liquidity Lenders,
the Liquidity Agent, the Series 1998-1 Letter of Credit Provider, the
Depositary, the Dealers and the Holders of the Commercial Paper Notes (the
foregoing being referred to as the "Secured Parties") as their respective
interests appear, and hereby grants to the Collateral Agent, for the benefit of
the Secured Parties, a security interest in all of DTFC's right, title and
interest in and to all assets, property and interests in property (other than
as specified below) whether now owned or hereafter acquired or created (all of
the foregoing being referred to as the "Assigned Collateral"), including
without limitation, all of the following property and interests in property:

                    (i)   the DTFC Agreements, including, without limitation,
         the Series 1998-1 Notes, all monies due and to become due to DTFC from
         RCFC under or in connection with the DTFC Agreements, whether payable
         as principal, interest, fees, expenses, costs, indemnities, insurance
         recoveries, damages for the breach of any of the DTFC Agreements or
         otherwise, and all rights, remedies, powers, privileges and claims of
         the Debtor against any other party under or with respect to the Series
         1998-1 Notes, the Series 1998-1 Supplement and other DTFC Agreements
         (whether arising pursuant to the terms of such DTFC Agreements or
         otherwise available to DTFC at law or in equity), the right to enforce
         the Series 1998-1 Notes, the Series 1998-1 Supplement or any other
         DTFC Agreement as provided herein and to give or withhold any and all
         consents, requests, notices, directions, approvals, extensions or
         waivers under or with





                                      -8-
<PAGE>   13
         respect to the Series 1998-1 Notes, the Series 1998-1 Supplement or
         any other DTFC Agreement or the obligations of any party thereunder;
         and

                    (ii)  all right, title and interest of DTFC in, to and
         under any Vehicle Disposition Program as they relate to the Existing
         Fleet or to the Financed Vehicles financed with the proceeds of the
         Series 1998-1 Notes, and all monies due and to become due in respect
         of such Vehicles from the Manufacturers under or in connection with
         the Vehicle Disposition Programs, whether payable as Vehicle
         repurchase prices, auction sales proceeds, fees, expenses, costs,
         indemnities, insurance recoveries, damages for breach of the Vehicle
         Disposition Programs or otherwise and all rights to compel performance
         and otherwise exercise remedies thereunder; and

                   (iii)  all additional property that may from time to time
         hereafter be subjected to the grant and pledge hereof by DTFC or by
         anyone on its behalf; and

                    (iv)  all property assigned to the Collateral Agent
         pursuant to Section 5.02, including the Accounts, the Series 1998-1
         Cash Collateral Account and the Deposited Funds; and

                    (v)   all proceeds, products and profits of and from any
         and all of the foregoing, including, without limitation, payments
         under insurance (whether or not the Collateral Agent is the loss payee
         thereof) or Vehicle warranties and cash.

Notwithstanding the foregoing, upon the disbursement by the Collateral Agent of
any amount distributable to DTFC in accordance with the terms of Section 2.01
or 5.02(b) for the payment of DTFC's operating and ordinary course expenses,
the security interest in such amount granted in favor of the Collateral Agent
shall be released.

         (b)  Notwithstanding the assignment and security interest so granted
to the Collateral Agent, DTFC shall nevertheless be permitted, subject to the
Collateral Agent's right to revoke such permission in the event of a Liquidity
Agreement Amortization Event (other than a Scheduled Liquidity Agreement
Amortization Event) or a Liquidation Event of Default and the provisions of
Section 4.03 hereof, to give all consents, requests, notices, directions,
approvals, extensions or waivers, if any, which are required to be given in the
normal course of business (which does not include waivers of defaults under any
of the DTFC Agreements or revocation of powers of attorney to RCFC) to RCFC by
DTFC by the specific terms of the Series 1998-1 Supplement or to any other
obligor under the Assigned Collateral, and the assignment of the Assigned
Collateral to the Collateral Agent shall not (i) relieve DTFC from the
performance of any term, covenant, condition or agreement on DTFC's part to be
performed or observed under or in connection with any of the DTFC Agreements or
from any liability to RCFC, the Collateral Agent or the Manufacturers, as the
case may be, or (ii) impose any obligation on any of the Secured Parties to
perform or observe any such term, covenant, condition or





                                      -9-
<PAGE>   14
agreement on DTFC's part to be so performed or observed or impose any liability
on any of the Secured Parties for any act or omission on the part of DTFC or
from any breach of any representation or warranty on the part of DTFC.  DTFC
hereby agrees to indemnify and hold harmless each Secured Party (which for
purposes of this Section 4.01(b) shall include their officers, directors,
employees and agents) from and against any and all losses, liabilities
(including liabilities for penalties), claims, demands, actions, suits,
judgments, reasonable out-of-pocket costs and expenses arising out of or
resulting from the assignment granted hereby by virtue of any act or omission
on the part of DTFC including, without limitation, the reasonable out-of-pocket
costs, expenses, and disbursements (including reasonable attorneys' fees and
expenses) incurred by any of the Secured Parties in enforcing this Collateral
Agreement or preserving any of their respective rights to, or realizing upon,
any of the Assigned Collateral other than any arising in connection with gross
negligence or willful misconduct on the part of any Secured Party.

         SECTION 4.02.            Application of Assigned Collateral and
Deposited Funds.  DTFC hereby acknowledges and agrees that, until this
Collateral Agreement is terminated, DTFC shall, and the Collateral Agent is
authorized to, cause all monies, instruments, cash and other proceeds due and
to become due to DTFC or the Collateral Agent under or in connection with the
Assigned Collateral for the Series 1998-1 Notes to be paid directly to the
Collateral Agent for deposit into the Collateral Account or such other account
as the Collateral Agent may from time to time specify to the Person making such
payments (and DTFC represents to the Secured Parties that it has instructed
RCFC and the Manufacturers, as applicable, to so remit such amounts).  DTFC
agrees that if any such monies, instruments, cash or other proceeds shall be
received by DTFC in an account other than the Collateral Account or in any
other manner, such monies, instruments, cash and other proceeds will not be
commingled by DTFC with any of its other funds or property, if any, but will be
held separate and apart therefrom and shall be held in trust by DTFC for, and
immediately paid over to, but in any event within two Business Days from
receipt, the Collateral Agent  with any necessary endorsement.  Provided that
the Collateral Account or any funds on deposit in, or otherwise to the credit
of, the Collateral Account are not then subject to any writ, order, judgment,
warrant of attachment, execution or similar process, all monies, instruments,
cash and other proceeds received by the Collateral Agent pursuant to this
Article IV shall be immediately deposited in the Collateral Account, and,
unless and until a Liquidity Agreement Amortization Event shall have occurred
and be continuing, shall be applied as provided in Section 5.02(b) hereof.  All
monies, instruments, cash and other proceeds held or deposited in the
Collateral Account after the occurrence and during the continuance of a
Liquidity Agreement Amortization Event and all monies, instruments, cash and
other proceeds received by the Collateral Agent pursuant to this Article IV
while the Collateral Account or any funds on deposit in, or otherwise to the
credit of, the Collateral Account are subject to any writ, order, judgment,
warrant of attachment, execution or similar process, shall be applied by the
Collateral Agent (to the extent permitted by law) to the payment or repayment
in full of all outstanding DTFC Obligations, in the appropriate order of
priority specified in Section 2.01 of this Collateral Agreement.





                                      -10-
<PAGE>   15
Notwithstanding the foregoing, to the extent that the aggregate amount of
proceeds relating to any Vehicle received in the Collateral Account exceeds the
Net Book Value of such Vehicle, the Collateral Agent shall, upon the written
direction of DTFC (on which it may conclusively rely), release such excess (to
the extent not previously applied hereunder) to RCFC within two Business Days
after the receipt of written instructions from the Master Servicer.

         SECTION 4.03.            Performance of Agreement.  (a) Upon the
occurrence of a Liquidation Event of Default, promptly following a request from
the Collateral Agent to do so and at DTFC's own expense, DTFC agrees to take
all such lawful action and as permitted under this Collateral Agreement as the
Collateral Agent may reasonably request to compel or secure the performance and
observance by RCFC or by any other party to any DTFC Agreement or any other CP
Program Document of its obligations to DTFC in accordance with the applicable
terms thereof, and to exercise any and all rights, remedies, powers and
privileges lawfully available to DTFC to the extent and in the manner
reasonably directed by the Collateral Agent, including, without limitation, the
transmission of notices of default and the giving of directions, or the
institution of legal or administrative actions or proceedings to compel or
secure performance by RCFC (or such party to any DTFC Agreement or any other CP
Program Document), of their respective obligations thereunder; provided,
however, that if DTFC shall have failed, within 2 Business Days of receiving
the direction by the Collateral Agent, to accomplish such directions of the
Collateral Agent, the Collateral Agent may, but shall not be obligated to, take
such previously directed action (and any related action as permitted under this
Collateral Agreement thereafter determined by the Collateral Agent to be
appropriate without the need under this provision or any other provision
hereunder to direct DTFC to take such action) on behalf of DTFC and the Secured
Parties.  Upon the occurrence of a Liquidation Event of Default, the Collateral
Agent may, and upon written direction from the Required Liquidity Providers
shall, take all lawful action at DTFC's expense (for reasonable costs and
expenses), to exercise any and all rights, remedies, powers and privileges
lawfully available to the Collateral Agent to the extent and in the manner
directed by the Required Liquidity Providers or, in the absence of such
direction, by the Collateral Agent itself, including, without limitation, the
transmission of notices of default and the institution of legal or
administrative actions or proceedings to compel or secure performance by RCFC,
DTFC or any obligor with respect to the Assigned Collateral (including, without
limitation, any Manufacturer under a Vehicle Disposition Program), and to
exercise any other remedies available to a secured party.

         Subject to Section 4.01(b), DTFC further agrees that it will not,
without the prior written consent of the Collateral Agent, exercise any right,
remedy, power or privilege available to it with respect to any obligor under
the Assigned Collateral, take any action to compel or secure performance or
observance by any obligor of its obligations to DTFC or give any consent,
request, notice, direction, approval, extension or waiver with respect to any
obligor.





                                      -11-
<PAGE>   16
         In the event of a Liquidation Event of Default, the Required Liquidity
Providers shall be deemed to have directed that the Collateral Agent, and RCFC
return each Vehicle to the related Manufacturer under the related Vehicle
Disposition Program at the end of the minimum holding period (if any) for such
Vehicle under the related Vehicle Disposition Program, unless the Required
Liquidity Providers specifically waive such direction in writing.

         (b)     Unless otherwise specifically directed by the Required
Liquidity Providers in writing, in the event that there has occurred a
Manufacturer Event of Default, and the Collateral Agent shall have received
written notice thereof from any Secured Party, the Collateral Agent agrees to
direct the Master Collateral Agent to sell any and all Vehicles covered by the
related Vehicle Disposition Program of such Manufacturer for the highest
purchase price offered at a public or private sale and, promptly upon receipt,
to deposit the proceeds of such sale into the Collateral Account for
application in accordance with Section 5.02(b) or 2.01, as applicable.

         SECTION 4.04.            Amendments; Waivers; Declaration of Default.
Without intending in any manner to derogate from the absolute nature of the
assignment granted to the Collateral Agent by this Collateral Agreement or the
rights of the Collateral Agent hereunder, DTFC agrees that it will not, without
giving prior written notice to the Rating Agencies and the Dealers and without
the prior written consent of the Required Liquidity Providers and the
Collateral Agent (to the extent the rights or duties of the Collateral Agent
are affected thereby), amend, modify, supplement, terminate, waive or
surrender, or agree to any amendment, modification, supplement, termination or
surrender of, the terms of any Assigned Collateral, or waive timely performance
or observance by any obligor of its obligations under the Assigned Collateral,
or any default on the part of any obligor under the Assigned Collateral;
provided, however, that DTFC may amend the terms of any Assigned Collateral if
such amendment is effected only to cure any ambiguity, to correct or supplement
any provision therein which may be inconsistent with any other provision
therein or which is otherwise defective, or to make any other provisions with
respect to matters or questions arising under such Assigned Collateral which
shall not be inconsistent with the provisions of such Assigned Collateral;
provided further, however, any such action pursuant to this clause shall not
adversely affect the interests of a Secured Party in any material respect.
DTFC will not agree to any such amendment, waiver or other change (i) if such
amendment, waiver or other change would have a material adverse effect on the
rights or interests of the Holders of the Commercial Paper Notes or (ii) if the
Collateral Agent shall not have received written confirmation of the Rating
Agencies that such amendment, waiver or other change will not result in the
downgrading or withdrawal of the then current ratings of the Commercial Paper
Notes by the Rating Agencies.  If any such amendment, modification, supplement
or waiver shall be so consented to by the Collateral Agent (to the extent
required) and the Required Liquidity Providers (to the extent required), DTFC
agrees, promptly following a request by the Collateral Agent or the Liquidity
Agent to do so, to execute and deliver, in its own name and at its own expense
(i) an officer's certificate and an opinion of counsel that such amendment is





                                      -12-
<PAGE>   17
in compliance with the requirements of this Collateral Agreement, and (ii) such
other agreements, instruments, consents and other documents as the Collateral
Agent or the Liquidity Agent, as the case may be, may deem necessary or
appropriate in the circumstances.  No consent by the Collateral Agent or any
other Secured Party to any such amendment, modification, supplement or waiver
shall be deemed to be a determination by the Collateral Agent that such
amendment, modification, supplement or waiver will not adversely affect the
rights of any Holder of Commercial Paper Notes.

         Upon the occurrence of a Liquidity Agreement Amortization Event, the
Collateral Agent, upon direction by the Required Liquidity Providers, shall
direct DTFC (i) not to make any further Advances under the Note Purchase
Agreement, and (ii) if no Commercial Paper Notes are then outstanding, to
declare, or to direct the Trustee to declare, the Series 1998-1 Notes
immediately due and payable.

         SECTION 4.05.            Notice of Default.  Promptly upon becoming
aware thereof, DTFC agrees to give the Liquidity Agent, the Liquidity Lenders,
the Depositary, the Dealers, the Collateral Agent and each Rating Agency prompt
written notice (and in no case more than two days after DTFC has actual
knowledge thereof) of each Liquidity Agreement Amortization Event or Potential
Liquidity Agreement Amortization Event and each default on the part of any

         SECTION 5.02.           Assignment of Accounts, etc.  (a) In order to

         purposes of this Section 5.02(b)(iv) on the date such Advance is made)
         from DTFC (a) to the Liquidity Lenders in connection with the
         Liquidity Advances made pursuant to the Liquidity Agreement, and (b)

         Series 1998-1 Cash Collateral Account) to fund any LOC Liquidity

         interest on any of the foregoing, together with all amounts payable in

         (excluding those referenced in clause (vi) below) at any time and





                                      -16-
<PAGE>   21
         from time to time due from DTFC to any of them under or in respect of
         the Liquidity Agreement, the Series 1998- 1 Letter of Credit, the CP
         Enhancement Letter of Credit Application and Agreement, and this
         Collateral Agreement, together with all amounts due from DTFC in
         respect of interest thereon, and the payment, pro rata, of all
         indemnities at any time and from time to time due from DTFC hereunder
         to the Liquidity Lenders or the Series 1998-1 Letter of Credit

         (v) shall relate exclusively to costs and expenses incurred in or in

         handling of funds and the making of such funds available to or for the
         account or benefit of DTFC and shall not include amounts payable in
         connection with general indemnity claims relating to the use by DTFC
         or the Series 1998-1 Letter of Credit Provider of the proceeds of such
         financial accommodations (other than, in the event such actions give
         rise to breakage costs, any action in the nature of a prepayment by
         DTFC) or actions taken or omitted to be taken by DTFC under the CP
         Program Documents and not directly related to the procurement of
         funds, all of which shall be covered by clause (vi) below;

                    (vi)   to the extent no Borrowing Base Deficiency results
         therefrom, the repayment, pro rata, of all reasonable amounts advanced
         or expended by the Collateral Agent, the Liquidity Agent, any

         hereunder or in connection with the Liquidity Agreement or the Series
         1998-1 Letter of Credit or the CP Enhancement Letter of Credit
         Application and Agreement (solely with respect to amounts due from
         DTFC under the CP Enhancement Letter of Credit Application and
         Agreement), as the case may be, and any other amounts and reasonable
         out-of-pocket costs and expenses due from DTFC to any Secured Party
         under or in connection with this Collateral Agreement, the Liquidity
         Agreement, the Series 1998-1 Letter of Credit, the CP Enhancement

                    (viii) the making of further Advances by DTFC under the Note
         Purchase Agreement for the purchase of the Series 1998-1 Invested
         Amount; and

                    (ix)  the balance of such Deposited Funds shall be retained
         in the appropriate Account and invested pursuant to Section 5.04 in
         Eligible Investments.

         (c)     The Collateral Agent shall apply moneys as provided in Section
5.02(b) promptly upon receipt of written or telephonic instructions from a DTFC
Agent or, with





                                      -17-
<PAGE>   22
respect to clause (b)(i) above, a Depositary Agent, or with respect to clause
(b)(iii) above, the Liquidity Agent.  Any telephonic instructions shall be
promptly confirmed in writing.  The Collateral Agent shall make the required
withdrawals and transfers on the same day provided that it shall have received
instructions prior to 2:00 p.m. (New York City time) on such day.  Absent
manifest error, the Collateral Agent shall have no responsibility for verifying
that moneys being transferred pursuant to this Section 5.02 are in the proper
amounts or that any conditions to such transfers are complied with.  All
instructions furnished to the Collateral Agent pursuant to this Section 5.02(c)
or 5.03 shall specify the account to which moneys are to be transferred;
provided that moneys payable to any Liquidity Lender shall be transferred to
the Liquidity Agent for distribution to such Liquidity Lender.

         (d)     The Collateral Agent shall, with the cooperation of the
Depositary and the Liquidity Agent, monitor the amount of Outstanding
Commercial Paper Notes, Outstanding Liquidity Advances (to be provided by the
Liquidity Agent), and the current Borrowing Base and CP Borrowing Base (each of
which is to be provided by DTFC), and determine whether or not a Borrowing Base
Deficiency or CP Borrowing Base Deficiency exists on any Business Day.  In this
regard, DTFC hereby agrees to provide the Collateral Agent and the Liquidity
Agent, (i) on or prior to the fifth (5th) Business Day of each month, a
statement reflecting the Borrowing Base as of the close of business on the last
day of the immediately preceding Related Month and (ii) promptly upon request
from the Collateral Agent or the Liquidity Agent, but in no event more than
three (3) Business Days from the date of such request, a statement reflecting
the Borrowing Base as of the close of business on the fifth (5th) Business Day
prior to the delivery of such statement, which statement shall, in each case,
be certified by the chief financial officer of DTFC.  DTFC shall provide copies
of such monthly statement to each Rating Agency and the Dealers.  Upon each
occasion that DTFC delivers a Borrowing Base Certificate to the Liquidity Agent
in accordance with the Liquidity Agreement, DTFC shall provide a copy of such
Certificate to the Collateral Agent hereunder.  The Collateral Agent may
conclusively rely on such certified statement or certificate at all times from
and after the issuance thereof until issuance of a new such certified statement
or certificate, without any obligation on the part of the Collateral Agent to
confirm the truth, accuracy or completeness of such certified statement or
certificate and without any obligation on the part of the Collateral Agent to
undertake any other inquiry with respect thereto.  Upon each occasion that DTFC
delivers information relating to the Borrowing Base to the Depositary in
accordance with Section 3(a) of the Depositary Agreement, DTFC shall provide a
copy of the notice containing such information to the Collateral Agent
hereunder.  DTFC agrees to notify the Collateral Agent promptly, and in any
event within one Business Day, upon its obtaining knowledge of the existence of
any Borrowing Base Deficiency or CP Borrowing Base Deficiency.

         (e)     The Collateral Agent shall from time to time, but at least
monthly, provide DTFC with statements of account relating to the Accounts and
the Series 1998-1 Cash





                                      -18-
<PAGE>   23
Collateral Account in accordance with the Collateral Agent's customary
practices and in a form reasonably satisfactory to the Collateral Agent and
DTFC.

         (f)     Upon the occurrence and during the continuance of a Liquidity
Agreement Amortization Event, all rights of DTFC to request the Collateral
Agent to withdraw or order the transfer of Deposited Funds from the Accounts or
the Series 1998-1 Cash Collateral Account shall cease, and the Collateral
Agent, at the direction (which direction shall be in writing or by telephone
(confirmed in writing promptly thereafter)) of the Required Liquidity Providers
shall (subject to Section 7.01 hereof), at any time and from time to time,
appropriate and apply the Deposited Funds then, or at any time thereafter, on
deposit in the Accounts or the Series 1998-1 Cash Collateral Account to the
payment or prepayment in full of all outstanding DTFC Obligations, whether or
not then due, in the order of priority specified in Section 2.01 hereof (or in
the case of the Series 1998-1 Cash Collateral Account, in accordance with
Section 4.18 of the Series 1998-1 Supplement).  The Collateral Agent shall make
all payments with respect to Commercial Paper Notes outstanding pursuant to
clause Second of Section 2.01 to the Depositary for application to the pro rata
payment, in accordance with their terms and subject to the provisions of the
Depositary Agreement, of the face amount of matured and unmatured Commercial
Paper Notes, whether or not such Commercial Paper Notes have been presented to
the Depositary for payment.

         SECTION 5.03.            Application of Deposited Funds and Assigned
Collateral.  For purposes of determining the payment to be made to any Person
of any Assigned Collateral and Deposited Funds pursuant to Sections 2.01 and
5.02 hereof, the Collateral Agent may rely on certificates or statements
furnished to or by it in accordance with the provisions of this Section 5.03;
provided, however, to the extent that the Collateral Agent has previously
received telephonic or written instructions with respect to determining the
payment to be made to any Person of any Assigned Collateral and Deposited Funds
pursuant to Section 5.02(c), the Collateral Agent may conclusively rely on such
previously received instructions.  For purposes of determining the application
to be made of Deposited Funds and any Assigned Collateral to any Holder
pursuant to clause Second of Section 2.01 and clause (i) of Section 5.02(b) or
to the Depositary pursuant to clause First of Section 2.01, clause Eighth of
Section 2.01 or Section 5.02(b)(ii)(b), the Collateral Agent may rely
exclusively upon a certificate or other statement (a copy of which shall at the
same time also be provided to DTFC) of the Depositary as to the amount then
owing to such Holder.  For purposes of determining the application to be made
of Deposited Funds and any Assigned Collateral to any Liquidity Lender, the
Liquidity Agent or the Series 1998-1 Letter of Credit Provider, pursuant to
clause Fourth, Fifth, Sixth or Eighth of Section 2.01 hereof (and the
corresponding provisions under Section 5.02(b)), the Collateral Agent may rely
exclusively upon a certificate or other statement (a copy of which shall at the
same time also be provided to DTFC) of the Liquidity Agent (with respect to
amounts owing to it or any Liquidity Lender) or the Series 1998-1 Letter of
Credit Provider, as the case may be, as to the amount then owing to any such
Liquidity Lender, the Liquidity Agent or the Series 1998-1 Letter of Credit
Provider, as the case may be.  Any application to





                                      -19-
<PAGE>   24
be made of Deposited Funds and Assigned Collateral to the Collateral Agent
pursuant to clause First or Seventh of Section 2.01 hereof (and the
corresponding provisions under Section 5.02(b)) may be made upon the Collateral
Agent's own certificate or statement delivered to DTFC and the Liquidity Agent,
setting forth in reasonable detail the nature of the Collateral Agent's claim
and the amount owing to the Collateral Agent on account thereof.  For purposes
of determining the application to be made of Deposited Funds and Assigned
Collateral to DTFC pursuant to clause Third or Ninth of Section 2.01 or the
corresponding provisions under Section 5.02(b) hereof or to any Dealer or any
other Person (other than any party hereto or any Liquidity Lender) pursuant to
clause Eighth of Section 2.01 or the corresponding provisions under Section
5.02(b) hereof, the Collateral Agent may rely conclusively upon a certificate
or other statement of DTFC as to the amount then owing to DTFC or such other
party.  The Collateral Agent shall not be liable for any application of the
Deposited Funds in accordance with any certificate or direction delivered
pursuant to this Section 5.03 or 5.02(c); provided, however, that no
application of the Deposited Funds and Assigned Collateral in accordance with
any certificate or statement delivered pursuant to this Section 5.03 or 5.02(c)
shall be deemed to restrict or limit the right of the Collateral Agent, DTFC,
the Liquidity Agent, the Depositary, any Liquidity Lender or any Dealer to
contest with the purported obligee its respective rights in respect of the
amount set forth in such certificate or statement.

         SECTION 5.04.            Eligible Investments.  So long as no
Liquidity Agreement Amortization Event (other than a Scheduled Liquidity
Agreement Amortization Event) shall have occurred and be continuing and all
DTFC Obligations due and owing by DTFC have been paid, monies held in the
Accounts shall be invested daily, and the proceeds of investments shall be
reinvested daily, by the Collateral Agent in overnight Eligible Investments
pursuant to the written direction of DTFC and, in all other cases, such monies
and proceeds shall be invested daily and reinvested daily by the Collateral
Agent in accordance with the written direction of the Liquidity Agent.  The
Trustee shall direct the investment of monies held in the Series 1998-1 Cash
Collateral Account in overnight Eligible Investments (or Eligible Investments
having longer maturities if (i) RCFC has consented thereto in the case of the
Series 1998-1 Cash Collateral Account and (ii) the Collateral Agent shall have
received written confirmation of the Rating Agencies that Eligible Investments
having such longer maturities will not result in the downgrading or withdrawal
of the then current ratings of the Commercial Paper Notes by the Rating
Agencies) at the direction of Master Servicer under the Master Lease with
respect to the Series 1998-1 Cash Collateral Account as provided in Section
4.18(c) of the Series 1998-1 Supplement; provided, however, that so long as a
Liquidity Agreement Amortization Event (other than a Scheduled Liquidity
Agreement Amortization Event) shall have occurred and be continuing, the
Liquidity Agent shall direct the investment of such monies as provided in the
Series 1998-1 Supplement.  The Collateral Agent shall not be responsible or
liable for any loss resulting from the investment performance of any investment
or reinvestment of monies held in the Accounts or any other account maintained
by the Collateral Agent for the purposes of this Collateral Agreement or in
Eligible Investments or from the sale or liquidation of any Eligible
Investments in accordance with this Collateral





                                      -20-
<PAGE>   25
Agreement.  All Eligible Investments shall be made in the name of, and shall be
payable to, the Collateral Agent, and all investment costs and expenses shall
be reimbursed to the Collateral Agent by DTFC.

         SECTION 5.05.            Liquidity Demand; Commitment Termination
Demand.  (a)  Upon receipt by the Collateral Agent on or prior to 12:15 p.m.
(New York City time) of a written notice from DTFC notifying the Collateral
Agent of the existence and amount of a Commercial Paper Deficit and instructing
the Collateral Agent to deliver a Borrowing Request, the Collateral Agent
shall, by 12:30 p.m. (New York City time) on the date of such notice (or, in
the case of any notice given to the Collateral Agent after 12:15 p.m. (New York
City time), by 12:30 p.m. (New York City time) on the next following Business
Day), deliver a Borrowing Request in the form of Exhibit B to the Liquidity
Agreement to the Liquidity Agent for a Borrowing in the aggregate in the amount
of such Commercial Paper Deficit; provided that if on the date any Borrowing
Request is to be delivered by the Collateral Agent, Deposited Funds are
available in the Termination Advance Account, the Collateral Agent shall
immediately transfer to the Commercial Paper Account such Deposited Funds (up
to the amount of the relevant Commercial Paper Deficit) and reduce the amount
demanded in the Borrowing Request by the amount of the Deposited Funds so
transferred.

         (b)     So long as the Series 1998-1 Letter of Credit shall not have
been terminated, upon receipt by the Collateral Agent on or prior to 12:30 p.m.
(New York City time) of a written notice from the Depositary notifying the
Collateral Agent of the existence and amount of a Liquidity Deficiency and
directing the Collateral Agent to direct the Enhancement Agent to make a draw
under the Series 1998-1 Letter of Credit, the Collateral Agent shall, by 1:00
p.m.  (New York City time) on the date of such notice (or, in the case of any
notice given to the Collateral Agent after 12:30 p.m. (New York City time), by
1:00 p.m. (New York City time) on the next following Business Day), direct the
Enhancement Agent to draw on the Series 1998-1 Letter of Credit in an amount
equal to the lesser of (i) such Liquidity Deficiency and (ii) the full amount
available to be drawn under the Series 1998-1 Letter of Credit on such date by
presenting a draft accompanied by a Certificate of Liquidity Demand in the form
of Annex B to the Series 1998-1 Letter of Credit.  No such draw under the
Series 1998-1 Letter of Credit shall be made unless as of the date of such draw
and after giving effect to all Liquidity Advances made on such date under the

telephone (promptly confirmed in writing) that the Aggregate Liquidity
Commitment is fully drawn under the Liquidity Agreement or is not available for
reasons other than a failure to meet conditions precedent.

                  THE COLLATERAL AGENT, THE LIQUIDITY LENDERS,
                                AND THE HOLDERS
                           OF COMMERCIAL PAPER NOTES

         SECTION 7.01.            Appointment and Powers of Collateral Agent.
The Secured Parties hereby appoint the Collateral Agent their agent hereunder,
and hereby authorize the Collateral Agent to take such action on their behalf
and to exercise such rights, remedies, powers and privileges hereunder as are
specifically authorized to be exercised by the Collateral Agent by the terms
hereof, together with such rights, remedies, powers and privileges as are
reasonably incidental thereto.  The parties hereto agree that the Collateral
Agent shall not be required to exercise any discretion or take any action or
refrain from taking any action in its capacity as agent for the Secured Parties
and DTFC, but shall only be required to act or refrain from acting in such
capacity (and shall be fully protected in so acting or refraining from acting)
upon the instruction of the Required Liquidity Providers or DTFC, as the case
may be, as provided herein.  The Collateral Agent may execute any of its duties
as agent hereunder by or through agents or employees and shall be entitled to
retain experts and to act in reliance upon the advice of such experts
concerning all matters pertaining to the agencies hereby created and its duties
hereunder, and shall not be liable for any action taken or omitted to be taken
by it in good faith in accordance with the advice of such experts selected by
it.  The relationship between the Collateral Agent and each of the Secured
Parties is that of agent and principal only, and nothing herein shall be deemed
to constitute the Collateral Agent a trustee for any of the Secured Parties or
impose on the Collateral Agent any obligations other than those for which
express provision is made herein.

         If the Collateral Agent receives unclear or conflicting instructions,
it shall be entitled to refrain from taking action until clear or
non-conflicting instructions are received, but shall inform the instructing
party or parties promptly of its decision to refrain from taking such action.
Except as required by the specific terms of this Collateral Agreement, the
Collateral Agent shall have no duty to exercise any rights, power, remedy or
privilege granted to it hereby, or to take any affirmative action hereunder or
thereunder, unless directed to do so by the Required Liquidity Providers (and
shall be fully protected in acting or refraining from acting pursuant to such
directions which shall be binding on the Secured Parties), and shall not,
without the prior approval of the Required Liquidity Providers, waive any
default on the part of DTFC, RCFC or the Manufacturers with respect to the
Assigned Collateral or amend, modify, supplement or terminate, or agree to any
surrender of, this Collateral Agreement or the Assigned Collateral.
Notwithstanding anything herein to the contrary, the Collateral Agent shall not
be required to take any action which the Collateral Agent has reasonably
determined that a reasonable likelihood exists that such action will expose the
Collateral Agent to personal or financial liability, unless indemnified to its
satisfaction, or which is contrary to this





                                      -23-

Collateral Agreement, or any other agreement or instrument relating to the
Assigned Collateral or applicable law.

         None of the Secured Parties nor any of its or their respective
directors, officers, employees or agents, shall be liable to any Secured Party
or any other Person for any action taken or omitted to be taken by it or them
hereunder, or in connection herewith, except for its or their own gross
negligence or willful misconduct; nor (except for its own due execution and
delivery thereof) shall the Collateral Agent be responsible to any Secured
Party for the validity, effectiveness, value, sufficiency or enforceability
against RCFC or DTFC of this Collateral Agreement or any other document
furnished pursuant hereto or in connection herewith, or of the Assigned
Collateral (or any part thereof), the Eligible Investments (or any part
thereof) or the Deposited Funds (or any part thereof).  Without limiting the
generality of the foregoing, the Collateral Agent:  (i) makes no warranty or
representation to any Secured Party and shall not be responsible to any Secured
Party for any statements, warranties or representations made by any other
Person in or in connection with this Collateral Agreement, the Series 1998-1
Supplement, the Vehicle Disposition Programs, the Liquidity Agreement, the
Master Lease or any other document relating to the Assigned Collateral; and
(ii) shall not have any duty to ascertain or to inquire as to the performance
or observance of any of the terms, covenants or conditions of this Collateral
Agreement, the Series 1998-1 Supplement, the Vehicle Disposition Programs, the
Liquidity Agreement, the Master Lease or any other agreements or instruments
relating to the Assigned Collateral on the part of any party hereto or thereto
or to inspect any books and records relating to the Assigned Collateral other
than as it determines reasonably necessary in the fulfillment of its own
obligations hereunder.

         The Collateral Agent shall be entitled to rely on any communication,
instrument, paper or other document reasonably believed by it to be genuine and
correct and to have been given, signed or sent by the proper Person or Persons.
The Collateral Agent shall be entitled to assume that no Liquidity Agreement
Amortization Event shall have occurred and be continuing and that the Accounts,
and any funds on deposit in or to the credit of such Accounts, are not subject
to any writ, order, judgment, warrant of attachment, execution or similar
process (collectively a "writ"), unless (i) in the case of any writ, an officer
in the asset finance department of the Collateral Agent has actual knowledge
thereof or (ii) the Collateral Agent has received written notice from the
Liquidity Agent or RCFC under the Liquidity Agreement that the Majority Banks
consider that such a Liquidity Agreement Amortization Event has occurred or
such writ has been issued and continues to be in effect, which notice specifies
the nature thereof.  The Collateral Agent may accept deposits from, lend money
to and generally engage in any kind of business with DTFC, any Manufacturer,
RCFC and their respective Affiliates as if it were not the agent of the
Liquidity Lenders and the Holders of Commercial Paper Notes.  The Collateral
Agent shall have the right to refrain from taking any action under Article VI
hereof unless it has received written directions from the appropriate parties
to take such action.

         SECTION 7.02.            Collateral Agents and Employees of the
Collateral Agent.  (i)  Each Liquidity Lender hereby agrees, in accordance with
its pro rata percentage of the sum of the Aggregate Liquidity Commitment under
the Liquidity Agreement, to indemnify and hold harmless the Collateral Agent
(which for purposes of this Section 7.02 shall include its officers, directors,
employees and agents)  (to the extent not reimbursed by DTFC), from and against
any and all losses (other than the Collateral Agent's loss of profit),
liabilities (including, liabilities for penalties), actions, suits, judgments,
demands, damages, out-of-pocket costs and expenses of any kind whatsoever
(including, without limitation, reasonable fees and expenses of counsel and
other experts) incurred or suffered by the Collateral Agent in its capacity as
agent hereunder as a result of any action taken or omitted to be taken by the
Collateral Agent in such capacity or otherwise incurred or suffered by, made
upon, or assessed against the Collateral Agent in such capacity to the extent
not reimbursed by DTFC or by application of the Assigned Collateral; provided
that no Liquidity Lender shall be liable for any portion of any such losses,
liabilities, actions, suits, judgments, demands, costs or expenses resulting
from or attributable to gross negligence or willful misconduct on the part of
the Collateral Agent or its agents or employees.  Without limiting the
generality of the foregoing, each Liquidity Lender hereby agrees, in the ratio
aforesaid, to reimburse the Collateral Agent promptly following its demand for
any out-of-pocket expenses (including, without limitation, reasonable fees and
expenses of counsel) incurred by the Collateral Agent hereunder and not
promptly reimbursed to the Collateral Agent by DTFC or by application of the
Assigned Collateral.  The obligations of each Liquidity Lender under this
paragraph shall survive the termination of this Collateral Agreement and the
Liquidity Agreement and the discharge of DTFC's obligations thereunder.  The
aggregate liability of the Liquidity Lenders hereunder for any claim shall be
limited to a percentage of the indemnity owing equal to the percentage that the
Aggregate Liquidity Commitment is of the Program Size.  If at any time,
following its demand therefor, the Collateral Agent shall not be reimbursed by
DTFC or by the Liquidity Lenders, the Collateral Agent is hereby authorized at
any time and from time to time, to the fullest extent permitted by law, to set
off and apply any and all amounts at any time held by the Collateral Agent for
the benefit of the Liquidity Lenders, including without limitation any such
amounts designated for disbursement to the Liquidity Lenders in accordance with
Section 2.01 or Section 5.02(b), against any and all of the obligations of the
Liquidity Lenders to the Collateral Agent now or hereafter existing under this
Collateral Agreement.  The Collateral Agent agrees promptly to notify each
Liquidity Lender after any such set-off and application made by the Collateral
Agent, provided that the failure to give such notice shall not affect the
validity of such set- off and application.  The rights of the Collateral Agent
under this Section are in addition to other rights and remedies which the
Collateral Agent may have.  Any such set-off against amounts owed to Liquidity
Lenders by the Collateral Agent shall not cause a payment default of DTFC on
amounts due to such Liquidity Lenders to the extent funds are available in the
Accounts to be allocated to the payment of all amounts due to the Liquidity
Lenders in accordance with Section 2.01 or 5.02(b), as applicable.

         (a)     No provision of this Collateral Agreement shall require the
Collateral Agent to expend or risk its own funds or otherwise incur any
financial or other liability in the performance of any duties hereunder or in
the exercise of any rights and powers hereunder.

         (b)     Any action or proceeding alleging any breach by the Collateral
Agent of duties under this Collateral Agreement shall be prosecuted only in the
courts of the State of New York located in the Borough of Manhattan, in New
York City or in the United States District Court for the Southern District of
New York.  The Collateral Agent shall have the right at any time to seek
instructions from any court of competent jurisdiction.  The Collateral Agent
may rely on the advice of counsel and shall be held harmless for actions taken
in reliance thereon.

         (c)     The Collateral Agent makes no representation as to, and shall
have no responsibility for, the correctness of any statement contained in, or
the validity or sufficiency of, this Collateral Agreement or any documents or
instruments referred to in this Collateral Agreement or the sufficiency or
effectiveness of any collateral assigned by this Collateral Agreement or as to
or for the validity or collectibility of any obligation contemplated by this
Collateral Agreement.  The Collateral Agent shall not be accountable for the
use or application by any person of disbursements properly made by the
Collateral Agent in conformity with the provisions of this Collateral
Agreement.

         (d)     The Collateral Agent may exercise any of its duties hereunder
by or through agents or employees.  The possession of the Assigned Collateral
by such agents or employees shall be deemed to be the possession of the
Collateral Agent.

         (e)     The provisions of this Section 7.02 shall survive the
termination of this Collateral Agreement or the resignation of the Collateral
Agent hereunder.

         SECTION 7.03.            Waiver of Jury Trial.  EACH OF THE PARTIES
HERETO KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT
OF, UNDER, OR IN CONNECTION WITH, THIS COLLATERAL AGREEMENT OR ANY OTHER CP
PROGRAM DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE PARTIES HERETO IN CONNECTION
HEREWITH OR THEREWITH.  EACH OF THE PARTIES HERETO ACKNOWLEDGES AND AGREES THAT
IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH
OTHER PROVISION OF EACH OTHER CP PROGRAM DOCUMENT TO WHICH IT IS A PARTY) AND
THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES HERETO ENTERING
INTO THIS COLLATERAL AGREEMENT AND EACH SUCH OTHER CP PROGRAM DOCUMENT.

         SECTION 7.04.            Successor Collateral Agent.  The Collateral
Agent acting hereunder at any time may resign by an instrument in writing
addressed and delivered, 30 days prior to the effectiveness of such
resignation, to each Liquidity Lender, the Liquidity Agent, the Dealers, DTFC,
each Rating Agency and the Depositary, and may be removed at any time with or
without cause by an instrument in writing duly executed by or on behalf of the
Required Liquidity Providers with written notice to each of the Rating
Agencies.  Subject to the provisions hereof, the Required Liquidity Providers
shall appoint, subject to the written consent of DTFC (which consent shall not
be unreasonably withheld), a successor to the Collateral Agent upon any such
resignation or removal, by an instrument of substitution complying with the
requirements of applicable law, or, in the absence of any such requirements,
without any formality other than appointment and designation in writing.  Upon
the making and acceptance of such appointment, the execution and delivery by
such successor Collateral Agent of a ratifying instrument pursuant to which
such successor Collateral Agent agrees to assume the duties and obligations
imposed on the Collateral Agent by the terms of this Collateral Agreement, and
the delivery to such successor Collateral Agent of the Assigned Collateral, the
Deposited Funds and documents and instruments then held by the retiring
Collateral Agent, such successor Collateral Agent shall thereupon succeed to
and become vested with all the estate, rights, powers, remedies, privileges,
immunities, indemnities, duties and obligations hereby granted to or conferred
or imposed upon the retiring Collateral Agent named herein, and one such
appointment and designation shall not exhaust the right to appoint and
designate further successor Collateral Agents hereunder.  No removal or
resignation of the Collateral Agent shall be effective unless and until a
successor Collateral Agent has been duly appointed, and the appointment of such
successor Collateral Agent has been accepted by such successor Collateral
Agent.  No Collateral Agent shall be discharged from its duties or obligations
hereunder until the Assigned Collateral, the Deposited Funds and documents and
instruments then held by such retiring Collateral Agent shall have been
transferred or delivered to the successor Collateral Agent in its capacity as
bank or trust company, until all Deposited Funds held in the Accounts and the
Series 1998-1 Cash Collateral Account maintained with or in the name of the
retiring Collateral Agent shall have been transferred to the new Collateral
Account and until such retiring Collateral Agent shall have executed and
delivered to the successor Collateral Agent appropriate instruments assigning
the retiring Collateral Agent's interest in the Assigned Collateral, the
Accounts, the Series 1998-1 Cash Collateral Account, the Deposited Funds and
Eligible Investments to the successor Collateral Agent.  If no successor
Collateral Agent shall be appointed, as aforesaid, or, if appointed, shall not
have accepted its appointment, within 30 days after notice of resignation or
removal of the retiring Collateral Agent, then, subject to the provisions
hereof, the retiring Collateral Agent may appoint a successor Collateral Agent
with the written consent of the Liquidity Agent and (so long as no Liquidity
Agreement Amortization Event (other than a Scheduled Liquidity Agreement
Amortization Event) then exists) DTFC, which consent shall not be unreasonably
withheld.  Each such successor Collateral Agent shall provide DTFC, each
Liquidity Lender, the Liquidity Agent and the Depositary with its address, and
telephone, telecopy, telex, E-Mail (if applicable) and TWX numbers, to be used
for purposes of Section 9.04 hereof, in a notice





                                      -27-
<PAGE>   32
complying with the terms of said Section.  Notwithstanding the resignation or
removal of any Collateral Agent hereunder, the provisions of this Article VII
shall continue to inure to the benefit of such retiring Collateral Agent in
respect of any action taken or omitted to be taken by such retiring Collateral
Agent in its capacity as such while it was Collateral Agent under this
Collateral Agreement.  DTFC shall provide prompt notice to each Rating Agency
of the appointment of a successor Collateral Agent.

         SECTION 7.05.            Qualifications of Collateral Agent.  Any
Collateral Agent at any time acting hereunder must at all times be (i) the
corporate trust department of a bank or trust company having its principal
office in the District of Columbia or one of the states located in the United
States, or (ii) a bank or trust company having its principal office in the
District of Columbia or one of the states located in the United States,
authorized to accept deposits, or a branch office or agency of a foreign bank
located in the District of Columbia or one of the states of the United States,
in each case having short-term ratings from Moody's and S&P at least equal to
the rating such Rating Agency then assigns to the Commercial Paper Notes.

         SECTION 7.06.            Instructions of the Required Liquidity
Providers and Other Parties.  In any instance in which the Collateral Agent is
permitted to take action hereunder, the Collateral Agent shall, except as
expressly provided herein or in the Liquidity Agreement, act in accordance with
the written instructions received, if any, from the Required Liquidity
Providers.  All instructions and notices from the Required Liquidity Providers
shall be submitted to the Collateral Agent through the Liquidity Agent.  All
instructions hereunder required to be given by the Majority Banks shall be
submitted to the Collateral Agent through the Liquidity Agent.


                                 ARTICLE VIII.

                AMENDMENTS, MODIFICATIONS, WAIVERS AND CONSENTS

         SECTION 8.01.           Execution of Amendments, etc.  No amendment,
modification, supplement, termination or waiver of or to any provision of this
Collateral Agreement or the defined terms used herein and set forth in the
Definitions List, nor any consent to any departure by DTFC from any provision
of this Collateral Agreement, shall be effective unless the same shall be in
writing and signed on behalf of the Collateral Agent, the Liquidity Agent on
behalf of the Majority Banks, the Depositary, the Series 1998-1 Letter of
Credit Provider and DTFC; provided, however, that (i) the written consent of
all Liquidity Lenders shall be necessary to the extent that any such amendment,
modification, supplement, termination, waiver or consent (a) releases the
assignment given hereunder in respect of any of the Assigned Collateral or (b)
affects this Section 8.01 or Section 2.01 or 5.02 and (ii) such amendment,
modification, supplement, termination or waiver shall not result in the
downgrading or the withdrawal of the then current ratings of the Commercial
Paper Notes provided by the Rating





                                      -28-
<PAGE>   33
Agencies as evidenced by written confirmation from the Rating Agencies.  Any
waiver of any provision of this Collateral Agreement, and any consent to any
departure by DTFC from the terms of any provision of this Collateral Agreement,
shall be effective only in the specific instance and for the specific purpose
for which given.  No notice to or demand upon DTFC in any instance hereunder
shall entitle DTFC to any other or further notice or demand in similar or other
circumstances.

         Notwithstanding the foregoing provisions of this Section 8.01, DTFC,
the Liquidity Agent and the Collateral Agent may, at any time and from time to
time, without the consent of the other Secured Parties, enter into any
amendment, supplement or other modification to this Collateral Agreement to
cure any apparent ambiguity or to correct or supplement any provision in this
Collateral Agreement that may be inconsistent with any other provision herein;
provided, however, that (i) any such action shall not have a material adverse
effect on the interests of the Liquidity Lenders and (ii) a copy of any such
amendment, supplement or other modification is furnished the other Secured
Parties, in accordance with the notice provisions hereof, not later than ten
days prior to the execution thereof.


                                  ARTICLE IX.

                                 MISCELLANEOUS

         SECTION 9.01.            Further Assurances.   DTFC (i) from time to
time, at its expense, will promptly execute and deliver all further instruments
and documents, and take all further action, that may be necessary, as
reasonably requested by the Collateral Agent, in order to perfect and protect
any security interest granted or purported to be granted hereby or to enable
the Collateral Agent to exercise and enforce its rights and remedies hereunder
with respect to any Assigned Collateral, including without limitation, the
execution of financing or continuation statements, or amendments thereto and
(ii) hereby authorizes the Collateral Agent, if directed by the Secured
Parties, to file one or more financing or continuation statements, and
amendments thereto, relative to all or any part of the Assigned Collateral
without the signature of DTFC, where permitted by law.  A carbon photographic
or other reproduction of this Assigned Collateral Agreement or any financing
statement covering the Assigned Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

         SECTION 9.02.            No Waiver; Cumulative Remedies.  No failure
on the part of the Collateral Agent to exercise, and no delay on the part of
the Collateral Agent in exercising any right, power or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power or remedy by the Collateral Agent preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.
All remedies hereunder are cumulative and are not exclusive of any other
remedies that may be available to the Collateral Agent, whether at law, in
equity or otherwise.

Disposition Program) shall be sent by DTFC, promptly upon becoming aware
thereof, to each Rating Agency which shall be required to confirm their ratings
on the Commercial Paper Notes prior to the effectiveness thereof.

         SECTION 9.04.            Notices, etc.  Except where telephonic

their signatures on the signature pages of the Liquidity Agreement, as such
addresses may be revised from time to time by written notice from such
Liquidity Lenders.

         SECTION 9.05.            Fee; Costs and Expenses, etc.  DTFC shall pay
to the Collateral Agent as its fee for its services the amounts (which amounts
are subject to change as circumstances warrant) as set forth in the Fee Letter
set forth as Exhibit A hereto.  DTFC hereby agrees to reimburse the Collateral
Agent for all reasonable out-of-pocket costs and expenses (including reasonable
counsel fees and expenses, but excluding costs and expenses solely attributable
to administrative overhead) incurred by the Collateral Agent in connection with
the administration and enforcement of this Collateral Agreement and agrees to
indemnify and hold harmless the Collateral Agent, the Depositary, the Liquidity
Agent and the Liquidity Lenders (which in each case for purposes of this
Section 9.05 shall include their respective officers, directors, employees and
agents) from and against any and all losses (other than loss of profit),
liabilities (including liabilities for penalties), actions, suits, judgments,
demands, reasonable out-of-pocket costs and expenses (including, without
limitation, reasonable attorneys' fees and expenses but excluding costs and
expenses attributable solely to administrative overhead) incurred by the
Collateral Agent (in its capacity as Collateral Agent), the Depositary, the
Liquidity Lenders or the Liquidity Agent in connection with the administration
or enforcement of this Collateral Agreement and also agrees to pay, indemnify,
and to hold each Liquidity Lender, the Collateral Agent, the Liquidity Agent
and the Depositary harmless from, any and all recording and filing fees and any
and all liabilities with respect to, or resulting from any delay in paying,
stamp and other taxes, if any, which may be payable or determined to be payable
in connection with the execution and delivery of, or consummation of any of the
transactions contemplated by, or any amendment, supplement or modification of,
or any waiver or consent under or in respect of, this Collateral Agreement;
provided, however, that DTFC shall not be required to indemnify any Secured
Party for any such loss, liability, action, suit, judgment, demand, cost or
expense due to willful misconduct or gross negligence on the part of such
Secured Party or its respective agents or employees. If DTFC shall fail to do
any act or thing which it has covenanted to do hereunder or any representation
or warranty on the part of DTFC contained herein or repeated and reaffirmed
herein shall be breached, the Collateral Agent may, with the consent of the
Required Liquidity Providers, but shall not be required to, do the same or
cause it to be done or remedy any such breach, and may expend its funds for
such purpose.  Any and all amounts so expended by the Collateral Agent shall be
repayable to it by DTFC upon the Collateral Agent's demand therefor.  The
obligations of DTFC under this Section 9.05 shall survive the termination of
this Collateral Agreement, the resignation or removal of any of the Secured
Parties and the discharge of the other obligations of DTFC hereunder and shall
also survive the termination of the Aggregate Liquidity Commitment of the
Liquidity Lenders and the termination of the Series 1998-1 Letter of Credit in
accordance with the provisions of the Liquidity Agreement and of the Series
1998-1 Letter of Credit, respectively.

         SECTION 9.06.            Collateral Agent Appointed Attorney-in-Fact.
DTFC hereby appoints the Collateral Agent its attorney-in-fact, with full power
of substitution, for the purpose of taking such action (including, without
limitation any action pursuant to Section 4.03 hereof) and executing
agreements, instruments and other documents, in the name of DTFC, as the
Collateral Agent or the Required Liquidity Providers may deem necessary or
advisable to accomplish the purposes hereof, which appointment is coupled with
an interest and is irrevocable.

         SECTION 9.07.            Termination; Assigned Collateral.  This
Collateral Agreement, and any grants, pledges and assignments hereunder, shall
terminate when (a) all DTFC Obligations shall have been fully paid and
satisfied, (b) the Aggregate Liquidity Commitment of the Liquidity Lenders
under the Liquidity Agreement, the Series 1998-1 Letter of Credit Commitment
and related documents have terminated, and (c) the Series 1998-1 Letter of
Credit shall have terminated, at which time the Collateral Agent, at the
written request of DTFC and upon receipt of a certificate from DTFC to the
effect that the conditions in clauses (a), (b) and (c) above have been complied
with and upon receipt of a certificate from the Liquidity Agent and the
Depositary to the effect that the conditions in clauses (a), (b) and (c)
relating to DTFC Obligations to the Liquidity Lenders and the Holders of
Commercial Paper Notes have been complied with, shall reassign (without
recourse upon, or any warranty whatsoever by, the Collateral Agent), deliver at
DTFC's expense all Assigned Collateral and documents then in the custody or
possession of the Collateral Agent promptly to DTFC and execute such documents
and instruments as DTFC may reasonably request in connection with such
reassignment.

         DTFC and the Secured Parties hereby agree that, if any Deposited Funds
remain on deposit in the Collateral Account after the termination of this
Collateral Agreement, such amounts shall be released by the Collateral Agent
and paid to DTFC.

         SECTION 9.08.            Governing Law; Binding Character; Assignment.
THIS COLLATERAL AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO OTHERWISE APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW.  This Collateral Agreement shall be binding
upon and shall inure to the benefit of DTFC, the Liquidity Lenders, the
Liquidity Agent, the Depositary, the Holders of Commercial Paper Notes and the
Collateral Agent, and their respective successors and assigns; provided,
however, that DTFC may not assign any of its right hereunder or in connection
herewith or any interest herein (voluntarily, by operation of law or otherwise)
without the prior written consent of all of the Liquidity Lenders.  This
Collateral Agreement shall not be construed so as to confer any right or
benefit upon any Person other than the parties to this Collateral Agreement,
the Liquidity Lenders and the Holders of the Commercial Paper Notes and each of
their respective successors and assigns.

         SECTION 9.09.            Severability of Provisions.  Any provision of
this Collateral Agreement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof or affecting the validity or enforceability of such provision
in any other jurisdiction.

         SECTION 9.10.             No Bankruptcy Petition Against DTFC.  Each of
the Secured Parties hereby covenants and agrees that, prior to the date which
is one year and one day after the payment in full of the latest maturing
Commercial Paper Note, it will not institute against, or join with any other
Person in instituting against, DTFC, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings, or other proceedings under
any Federal or state bankruptcy or similar law; provided, however, that nothing
in this Section 9.10 shall constitute a waiver of any right to indemnification,
reimbursement or other payment from DTFC pursuant to this Collateral Agreement.
In the event that any such Secured Party takes action in violation of this
Section 9.10, DTFC agrees that it shall file an answer with the bankruptcy or
otherwise properly contest the filing of such a petition by any such Secured
Party against DTFC or the commencement of such action and raise the defense
that such Secured Party has agreed in writing not to take such action and
should be estopped and precluded therefrom and such other defenses, if any, as
its counsel advises that it may assert.  The provisions of this Section 9.10
shall survive the termination of this Collateral Agreement, and the resignation
or removal of the Collateral Agent, the Liquidity Agent or the Depositary.
Nothing contained herein shall preclude participation by any Secured Party in
assertion or defense of its claims in any such proceeding involving DTFC.

         SECTION 9.11.            No Recourse.  The obligations of DTFC under
this Collateral Agreement are solely the corporate obligations of DTFC.  No
recourse shall be had for the payment of any amount owing in respect of Section
9.05 hereof or for the payment of any fee hereunder or any other obligation or
claim arising out of or based upon this Collateral Agreement against any
stockholder, employee, officer, director, Affiliate or incorporator of DTFC;
provided, however, that nothing in this Section 9.11 shall relieve any of the
foregoing Persons from any liability which such Person may otherwise have for
its gross negligence or willful misconduct.  The provisions of this Section
9.11 shall survive the termination of this Collateral Agreement.

         SECTION 9.12.            Confidentiality.  Each party hereto (other
than DTFC) agrees that it shall not disclose any Confidential Information to
any Person without the prior written consent of RCFC or DTFC. Notwithstanding
anything herein to the contrary, the foregoing shall not be construed to
prohibit any party hereto from (i) disclosing any and all information that is
or becomes publicly known through no fault of a Secured Party, (ii) disclosure
of any and all information (which makes reference to RCFC or DTFC or this
transaction) obtained by any Secured Party from sources (other than RCFC or
DTFC) that have not notified the Secured Party or Parties that such information
is subject to a confidentiality obligation with RCFC or





                                      -35-
<PAGE>   40
DTFC (iii) disclosing any and all information (A) if required to do so by any
applicable statute, law, rule or regulation, (B) to any government agency or
regulatory body having or claiming authority to regulate or oversee any aspects
of a Secured Party's business or that of its Affiliates, (C) pursuant to any
subpoena, civil investigative demand or similar demand or request of any court,
regulatory authority, arbitrator or arbitration to which any Secured Party or
an Affiliate or an officer, director or employee thereof is a party, (D) in any
preliminary or final offering circular, registration statement or contract or
other document pertaining to the transactions contemplated herein approved in
advance by RCFC or DTFC or (E) to any Affiliate, independent or internal
auditor, agent, employee or attorney of any Secured Party having a need to know
the same, provided that the Secured Party advises such recipient of the
confidential nature of the information being disclosed or (iv) any other
disclosure authorized by RCFC or DTFC.

         "Confidential Information" means information that RCFC or DTFC
furnishes to a Secured Party on a confidential basis, but does not include any
such information that is or becomes generally available to the public other
than as a result of a disclosure by such Secured Party or other person to which
Secured Party delivered such information or that is or becomes available to
such Secured Party from a source other than RCFC or DTFC, provided that such
source is not (1) known to such Secured Party to be bound by a confidentiality
agreement with RCFC or DTFC, as the case may be, or (2) known to such Secured
Party to be otherwise prohibited from transmitting the information by a
contractual, legal or fiduciary obligation.

         SECTION 9.13.            Headings.  Article and Section headings used
in this Collateral Agreement are for convenience of reference only and shall
not affect the construction of this Collateral Agreement.

         SECTION 9.14.            Execution in Counterparts.  This Collateral
Agreement may be executed in any number of counterparts and by different
parties hereto on separate counterparts, each of which counterparts, when so
executed and delivered, shall be deemed to be an original and all of which
counterparts, taken together, shall constitute one and the same Collateral
Agreement.

         SECTION 9.15.            Limited Recourse to DTFC.  The Collateral
Agent agrees that the obligations of DTFC to the Collateral Agent hereunder
shall be payable in the order and priority set forth in Section 2.01 and
5.02(b), as applicable, of this Collateral Agreement.  Such obligations shall
be due and payable only to the extent that DTFC's assets and the Series 1998-1
Letter of Credit Commitment are sufficient to pay such obligations.  No claims
of the Collateral Agent arising under or in connection with this Collateral
Agreement are intended to be impaired or waived by this Section 9.15.

         SECTION 9.16.            Waiver of Set-Off With Respect to DTFC.  Each
of the Collateral Agent, the Depositary, the Series 1998-1 Letter of Credit
Provider and the Liquidity Agent





                                      -36-

hereby waives and relinquishes any right (other than for its fees and expenses)
that it has or may have to set-off or to exercise any banker's lien or any
right of attachment or garnishment with respect to any funds at any time and
from time to time on deposit in, or otherwise to the credit of, any account and
any claims of DTFC therein or with respect to any right to payment from DTFC,
it being understood, however, that nothing contained in this Section 9.16
shall, or is intended to, derogate from the assignment and security interest
granted to the Collateral Agent under this Collateral Agreement or impair any
rights of the Secured Parties or the Collateral Agent hereunder or thereunder.

         SECTION 9.17.            Obligations of Collateral Agent Under the
Note Purchase Agreement.  The Collateral Agent hereby acknowledges and agrees
to its duties and obligations set forth in the Note Purchase Agreement, as such
agreement may be amended, amended and restated, supplemented or otherwise
modified from time to time in accordance with the terms thereof.

                                DEALER AGREEMENT


         THIS DEALER AGREEMENT, dated as of March 4, 1998 (as the same may be
amended, supplemented, amended and restated or otherwise modified from time to
time in accordance with the terms hereof, this "Agreement"), among DOLLAR
THRIFTY FUNDING CORP., an Oklahoma corporation ("DTFC" or the "Company"), DOLLAR
THRIFTY AUTOMOTIVE GROUP, INC., a Delaware corporation ("DTAG"), CREDIT SUISSE
FIRST BOSTON CORPORATION, a Massachusetts corporation ("CSFB"), as a dealer, and
CHASE SECURITIES INC., a Delaware corporation ("Chase"), as a dealer (each of

                              W I T N E S S E T H:

         WHEREAS, the Company has requested each Dealer to act as a commercial

from date of issue (collectively, the "Commercial Paper Notes").

         WHEREAS, the Commercial Paper Notes will be represented by either

note (the "Master Note") issued by the Company pursuant to that certain
Depositary Agreement, dated as of March 4, 1998, between the Company and Bankers
Trust Company, a New York banking corporation, as Depositary (as the same may be
amended, supplemented, amended and restated or otherwise modified from time to
time in accordance with the terms thereof and in effect, the "Depositary
Agreement"). Commercial Paper Notes represented by a master note shall be
referred to herein as "Book-Entry Notes". Certificated Notes shall be issued
substantially in the form of Exhibit A to the Depositary Agreement, while the
Master Note shall be issued substantially in the form of Exhibit E to the
Depositary Agreement.

         WHEREAS, each Dealer has indicated its willingness to act as dealer for

investigation and inquiry into the Company's business as each Dealer deems
appropriate under the circumstances.

         NOW THEREFORE, in consideration of the premises and the agreements
herein contained, and for due and adequate consideration which the parties
hereto hereby acknowledge, the parties hereto hereby agree as follows:

         1. Certain Definitions. For all purposes of this Agreement, except as
otherwise expressly provided herein or unless the context otherwise requires,
capitalized terms not otherwise defined herein shall have the meanings assigned
to such terms in, or incorporated by reference into,
<PAGE>   2
(i) the Definitions List attached as Annex A to that certain Liquidity
Agreement, dated as of March 4, 1998 (as the same may be amended, restated,
supplemented or otherwise modified from time to time in accordance with the
terms thereof, the "Liquidity Agreement"), among the Company, certain financial
institutions as Liquidity Lenders and Credit Suisse First Boston, a Swiss
banking corporation, as the Liquidity Agent for the Liquidity Lenders, as such
Definitions List may be amended, supplemented, amended and restated or otherwise
modified from time to time in accordance with the terms of the Liquidity
Agreement, (ii) the Series 1998-1 Supplement, dated as of March 4, 1998 (as the
same may be amended, restated, supplemented or otherwise modified from time to
time in accordance with the terms thereof, the "Series 1998-1 Supplement"),
between Rental Car Finance Corp., an Oklahoma corporation ("RCFC"), as issuer,
and Bankers Trust Company, a New York banking corporation, as trustee (in such
capacity, the "Trustee") and enhancement agent (in such capacity, the
"Enhancement Agent"), to the Base Indenture, dated as of December 13, 1995 (as
amended as of December 23, 1997, and as the same may be further amended,
restated, supplemented or otherwise modified from time to time in accordance
with the terms thereof, the "Base Indenture"), between RCFC and the Trustee, and
(iii) the Definitions List attached as Schedule 1 to the Base Indenture, as such
Definitions List may be amended, restated, supplemented or otherwise modified
from time to time in accordance with the terms of the Base Indenture, provided
that to the extent, if any, that any capitalized term used but not defined
herein has a meaning assigned to such term in more than one of the documents
referred to in clauses (i) though (iii) above, then (x) if a meaning is assigned
to such term in the Definitions List attached as Annex A to the Liquidity
Agreement, such meaning shall apply herein, and (y) if a meaning is not assigned
to such term in the Definitions List attached as Annex A to the Liquidity
Agreement, then the meaning assigned to such term in the Series 1998-1
Supplement shall apply herein.

         2. Appointment as Dealer. (a) The Company hereby appoints the Dealers
as dealers for the Commercial Paper Notes and acknowledges that the Dealers
shall have the right to assist the Company in the sale or placement of the
Commercial Paper Notes during the term of this Agreement. The Company agrees
that during the period the Dealers are acting as the Company's dealers
hereunder, the Company shall not directly contact or solicit potential investors
to purchase the Commercial Paper Notes. The Company further agrees during such
period that it will not engage any person or party other than the Dealers to
assist in the sale or placement of the Commercial Paper Notes unless any such
additional dealer enters into an agreement with the Company that is in form and
substance substantially similar to this Agreement. The Company further agrees to
provide the Dealers with a copy of any such other agreement immediately
following the execution thereof. While the Dealers shall not have any obligation
to purchase, as principal, Commercial Paper Notes from the Company, or to offer
or sell any Commercial Paper Notes, under any circumstances, and while the
Company shall have no obligation to sell Commercial Paper Notes to, or to
arrange sales of Commercial Paper Notes through, the Dealers, each Dealer may,
from time to time, with the consent of the Company (oral or written), purchase
in its sole discretion Commercial Paper Notes, as principal, from the Company.

<PAGE>   3
         (b) The Company and each Dealer respectively agree that any Commercial
Paper Notes, the placement of which such Dealer arranges or which are purchased
by such Dealer, shall be placed or purchased by such Dealer in reliance on the
representations, warranties, covenants and agreements of the Company contained
herein or made pursuant hereto and on the terms and conditions and in the manner
provided herein. All transactions involving the Commercial Paper Notes between a
Dealer and the Company shall be in accordance with the generally accepted custom
and practice prevailing in the commercial paper market at such times.

         (c) Upon receipt of instructions from the Company, each Dealer will
solicit purchases of such principal amount of the Commercial Paper Notes and
with such discounts, interest rates and maturities as the Company and such
Dealer shall agree upon from time to time during the term of this Agreement.
Such Dealer shall have no liability to the Company in the event any such
purchase is not consummated for any reason. Unless otherwise instructed by the
Company, each Dealer will periodically communicate to the Company, orally or in
writing, the aggregate purchase of Commercial Paper Notes arranged by such
Dealer with third party investors, other than offers rejected by such Dealer.
Each Dealer shall have the right, in its discretion reasonably exercised, to
reject any proposed purchase of Commercial Paper Notes, in whole or in part.

         (d) The Company may instruct any Dealer to suspend solicitation of
purchases of Commercial Paper Notes at any time (other than Commercial Paper
Notes held by any Dealer as principal). Upon receipt of such instruction, such
Dealer will forthwith suspend solicitation until such time as the Company has
advised it that solicitation of purchases may be resumed.

         3. Offers and Sales of the Commercial Paper Notes. The Commercial Paper
Notes are to be exempt from the registration requirements of the Securities Act
of 1933, as amended (the "Act"), pursuant to Section 3(a)(3) thereof. The
Dealers and the Company hereby establish the following procedures in connection
with the offer and sale or resale of the Commercial Paper Notes:

         (a) No sale of Commercial Paper Notes to any one purchaser will be for
less than $100,000 face amount and no Commercial Paper Note will be issued in a
smaller face amount. If the purchaser is a non-bank fiduciary acting on behalf
of others, each person for whom it is acting must purchase at least $100,000
face amount of the Commercial Paper Notes.

         (b) The Commercial Paper Notes will bear such interest rates (if
interest-bearing), or will be sold at such discounts from their face amounts, as
shall be mutually agreed to by the Company (after consultation with DTAG) and
the Dealers at the time of each proposed purchase or placement.

         (c) The proceeds from the sale of the Commercial Paper Notes will be
used by the Company for current transactions within the meaning of Section
3(a)(3) of the Act.

         (d) The Commercial Paper Notes will be issued by the Company in the
ordinary course of its business and financial affairs, will have a maturity at
the time of issuance of not more than fifty-eight (58) days (exclusive of days
of grace) and will not contain any provision for automatic "rollover".

         (e) In connection with the offer and sale of the Commercial Paper Notes
from time to time, offering materials will be prepared by the Company, including
vehicle experience reports, a commercial paper offering memorandum (as
supplemented or otherwise modified or substituted or replaced from time to time,
the "Offering Memorandum") relating to the Company and the transactions
contemplated by the CP Program Documents. Such vehicle experience reports, the
Offering Memorandum and the audited balance sheets and statements of income,
retained earnings and cash flows of DTAG and its Subsidiaries on a consolidated
basis for the two most recent fiscal years with respect to which such

Subsidiaries on a consolidated basis as of the end of the most recent fiscal
quarter with respect to which such information is available and the
corresponding fiscal quarter for the immediately prior year, together with any
other documents approved by the Company for distribution to each purchaser or
prospective purchaser of the Commercial Paper Notes and all documents
incorporated therein are referred to collectively herein as the "Offering

to each purchaser or prospective purchaser of the Commercial Paper Notes. The
Offering Materials will describe, among other things, (i) the Commercial Paper
Notes, (ii) the proposed use of proceeds of sale of the Commercial Paper Notes,
(iii) the business of the Company, and (iv) the terms of and parties to the CP
Program Documents. All documents incorporated by reference into the Offering
Materials (if any) will be offered to each prospective purchaser of Commercial
Paper Notes at no charge. In connection with such Offering Materials and to
assist the normal credit review procedures of each Dealer, the Company agrees to
furnish such Dealer on a continuing basis with such information concerning the
business of the Company (including financial statements), the offering and sale
of the Commercial Paper Notes and the related transactions as such Dealer
reasonably requests, provided that such Dealer enters into a confidentiality
agreement substantially in the form of Exhibit A attached hereto (the
"Confidentiality Agreement"). Any such information may only be disclosed by any
of the Dealers (i) pursuant to the terms of the Confidentiality Agreement or
(ii) if (A) the party to whom such information is being disclosed signs a
confidentiality agreement substantially similar to the Confidentiality Agreement
and (B) such disclosure is approved by the Company.

         (f) The Offering Materials will not be distributed by any Dealer unless
it is in a form satisfactory to such Dealer and the Company. No Dealer shall be
responsible for any inaccuracy in the Offering Materials except to the extent
such statement was provided in writing by such Dealer expressly for use in the
Offering Materials, provided that the parties acknowledge that the only
information provided by such Dealer for use in the Offering Materials is: with

         continuing. The execution and delivery of this Agreement, the
         Depositary Agreement, the Commercial Paper Notes and the other CP
         Program Documents to which the Company is a party and the incurrence of
         the obligations and consummation of the transactions herein
         contemplated (i) will not conflict with, or constitute a breach of or
         default under, the certificate of incorporation and by-laws of the
         Company or any material contract, indenture, mortgage, loan agreement
         or lease, to which the Company is a party or by which the Company may

         duly authorized, executed and delivered by the Company and constitutes
         the legal, valid and binding obligation of the Company enforceable
         against the Company in accordance with its terms, except as enforcement
         thereof may be limited by bankruptcy, insolvency or other similar laws

         or by general equitable principles.

                  (iv) The Commercial Paper Notes have been duly authorized for
         issuance, offer and sale as contemplated by this Agreement and, when
         issued and delivered against payment of the purchase price therefor,
         will constitute legal, valid and binding obligations of the Company
         enforceable against the Company in accordance with their terms, except
         as enforcement thereof may be limited by bankruptcy, insolvency, or

         or qualification of or with any court or any regulatory authority or
         other governmental agency or body (including the Securities and
         Exchange Commission) is required for the issuance, offer or sale of the

         and the other CP Program Documents.

                  (vi) There are no legal or governmental proceedings pending to
         which the Company is a party or of which any property of the Company is
         the subject, other than as set forth in the Offering Memorandum and
         other than legal or governmental proceedings which, in each case, will
         not have a Material Adverse Effect on the Company's ability to perform
         its obligations under this Agreement, the Depositary Agreement, the
         Commercial Paper Notes and each other CP Program Document; and to the
         best of its knowledge, no such proceedings are threatened or
         contemplated by governmental authorities or threatened by others.

                  (vii) The Company is not an "investment company", or a company
         "controlled" by an "investment company" within the meaning of the
         Investment Company Act of 1940, as amended.

         in all material respects and are repeated herein as though fully set
         forth herein.

                  (xi) The Offering Materials (including the documents
         incorporated therein by reference) do not, and the Offering Materials
         (including the documents incorporated by reference therein) as amended,
         supplemented or otherwise modified or substituted or replaced from time
         to time do not and will not contain any untrue statement of a material

         fact or omit to state a material fact necessary to make the statements

         to which DTAG is a party has been duly authorized, executed and
         delivered by DTAG and constitutes the legal, valid and binding
         obligation of DTAG enforceable in accordance with its terms, except as
         enforcement thereof may be limited by bankruptcy, insolvency or other
         similar laws relating to or affecting generally the enforcement of
         creditors' rights or by general equitable principles.

                  (iii) All representations and warranties of DTAG made in any
         CP Program Document to which DTAG is a party are true and correct in
         all material respects and are repeated herein as though fully set forth
         herein.

         5. Additional Representation and Warranty. Each acceptance by the
Company of an offer for the purchase of Commercial Paper Notes shall be deemed
an affirmation by the Company and (as to (i) and (iv) below) by DTAG that (i)
the representations and warranties of the Company and DTAG set forth in Section

extent such representations and warranties relate solely to an earlier date, in
which case such representations and warranties were true and correct as of such
earlier date), and an undertaking that such representations and warranties will
be true and correct at the time of delivery, to the purchaser or its agent of
the Commercial Paper Note or Commercial Paper Notes relating to such acceptance,
as though made at and as of such time (it being understood that insofar as such
representations and warranties relate to the Offering Materials, such
representations and warranties shall relate to the Offering Materials delivered
to prospective purchasers of Commercial Paper Notes at the time of such
acceptance and at the time of such delivery of the Commercial Paper Note or
Commercial Paper Notes relating to such acceptance, respectively), (ii) since
the date of the most recent Offering Materials, there has been no material
adverse change in the financial condition or operations of the Company which has
not been disclosed to the Dealers in writing, (iii) the conditions precedent to
the issuance of the Commercial Paper Notes set forth in the CP Program Documents

<PAGE>   8
Documents are true and correct in all material respects on and as of such date

and the other CP Program Documents required to be performed by the Company on or

         6. Covenants. (a) The Company will supply to each Dealer, on a

the sale of the Commercial Paper Notes and (ii) such funds as, together with the
proceeds of the Commercial Paper Notes, shall be necessary to make all payments
in respect of the Commercial Paper Notes, shall be deposited in such account,
which shall be maintained at the Depositary separate and apart from any other
account, but which may be subdivided into separate sub-accounts for bookkeeping
purposes. The Company will take all action necessary to ensure that the proceeds
from the sale of the Commercial Paper Notes will be used for purposes which meet
the "current transactions" requirements of Section 3(a)(3) of the Act.

         (c) The Company will not use the proceeds of Commercial Paper Notes
purchased and held by a Dealer, as principal, for the purchase or carrying of
securities to the extent that such use would result in a violation of
Regulations G, T, U or X promulgated by the Board of Governors of the Federal
Reserve System.

         (d) Without the prior written consent of each Dealer, the Company will
not permit to become effective (i) any amendment, supplement, rider, waiver,
termination, or consent to or under any Commercial Paper Note, the Depositary
Agreement or any other CP Program Document to which it is a party which might
adversely affect the interests of the holder of any Commercial Paper Notes then
outstanding (provided, that an amendment, supplement, rider, waiver,
termination, or consent relating to a change in the rating to "A-2" by S&P,
"P-2" by Moody's and "D-1-" by DCR shall become effective without the prior
written consent of each Dealer), provided that each Dealer is given sixty (60)

written notice of any such proposed amendment, supplement, rider, waiver,
termination, consent or assignment at least ten days prior to the effective date
thereof, and will furnish prior notice to the Dealers of any proposed
resignation, termination or replacement of the Depositary. The Company agrees
promptly to provide each of the Dealers with copies of any amendment,
supplement, rider, waiver, termination, or consent to or under any Commercial
Paper Note, the Depositary Agreement or any other CP Program Document.

         (e) The Company will immediately notify each Dealer of any downgrade of
which it has knowledge, or notice received by the Company of a potential
downgrade, in the rating of the Commercial Paper Notes, in any event prior to
any subsequent issuance of Commercial Paper Notes, and will promptly send to
each Dealer a copy of any notice or letter to that effect from S&P, Moody's or
DCR.

         (f) The Company will use good faith efforts to arrange for the
qualification of the Commercial Paper Notes for sale under the state securities
or "blue sky" laws of such jurisdictions in the United States as any Dealer may
reasonably request in writing and will maintain such qualification in effect as
long as required for the distribution of the Commercial Paper Notes in such
jurisdiction; provided, however, that the Company shall not be required to
become subject to service of process or franchise taxation as a foreign
corporation in any jurisdiction where it was not theretofore so subject.

         (g) The Company agrees to update the Offering Materials as necessary so
that at the time of each sale by a Dealer of Commercial Paper Notes, the
Offering Materials, as so updated, will not contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. Each of DTAG and the Company shall promptly inform each of the
Dealers if any event occurs or condition exists which makes it necessary to
revise, amend or supplement the Offering Materials in order that the Offering
Materials will not contain an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading. Prior to
any offer or sale of Commercial Paper Notes, each Dealer shall, with the
cooperation and consent of DTAG and the Company have the right to make such
reasonable due diligence investigation of the business of DTAG and the Company
as is usual in the course of continuous offerings of commercial paper.

         (h) The Company has credit facilities under the Liquidity Agreement and
the Series 1998-1 Letter of Credit and will at all times maintain in effect
committed credit facilities and/or cash collateral accounts with unutilized
available amounts thereunder not less than the principal (plus interest, if any,
to maturity) amount of outstanding Commercial Paper Notes and will advise, and
cause the Collateral Agent to advise the Dealers, as frequently as the Dealers
may request, of the status and usage of such credit facilities.


                                       -9-
<PAGE>   10
         (i) The Company will provide each Dealer with each notice or copy of
notice required to be provided by the Company to the Dealers under this
Agreement or any other CP Program Document.

         (j) For the period commencing on the date hereof and ending the date
that is one year and one day after the date upon which all Commercial Paper
Notes are paid in full, the Company agrees that each contract to which the
Company is or will be a party (other than contracts for trade payables or
contracts arising in connection with other ordinary operating expenditures)
shall include a provision pursuant to which each party thereto shall agree that,
prior to the close of such period, it will not institute against, or join any
other person in instituting against, the Company any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceeding, or other proceeding under any
bankruptcy or similar law.

         (k) Without limiting any obligation of the Company pursuant to this
Agreement to provide the Dealers with credit and financial information, the
Company hereby acknowledges and agrees that each Dealer may share and exchange
Offering Materials and any other information or matters relating to the Company
or the transactions contemplated hereby with any of its Affiliates, consistent
with the Confidentiality Agreements to be entered into by the Dealers pursuant
to this Agreement, in the following circumstances: (1) for approving lines of
credit, drawings or borrowings thereunder, and (2) in connection with commercial
paper underwriting, arrangement or sale.

         7. Conditions Precedent to Sale or Placement of the Commercial Paper

form reasonably acceptable to such Dealer, (ii) a certificate of the Secretary
or other appropriate officer of each of the Company and DTAG certifying true
copies of the resolutions of the Company and DTAG, respectively, approving this
Agreement, the Commercial Paper Notes, the Depositary Agreement and each other
CP Program Document to which the Company or DTAG is a party and the transactions
contemplated hereby and thereby and certifying the incumbency, authority and
true signatures of the officers of the Company and DTAG, respectively,
authorized to sign this Agreement, the Commercial Paper Notes, the Depositary
Agreement and each other CP Program Document to which the Company or DTAG is a
party, (iii) an original executed copy, photocopy or conformed copy of this
Agreement, the Depositary Agreement each other CP Program Document, which shall
be in form and substance reasonably acceptable to each Dealer, (iv) the letters
from the Rating Agencies regarding the ratings described in paragraph (b) below,
(v) a certified copy of the Company's certificate of incorporation and its
by-laws and (vi) true and correct copies any documents relating to Commercial

<PAGE>   11
         (b) Prior to the initial sale of any Commercial Paper Notes hereunder,
such Commercial Paper Notes shall have been rated at least "A-1" by S&P, "P-1"
by Moody's and "D-1" by DCR, the Commercial Paper Notes shall be rated so by
each of S&P, Moody's and DCR upon each subsequent sale of Commercial Paper Notes
hereunder or shall be rated such other rating as may be acceptable to the
Dealers; provided, however, that the Dealers hereby agree that a rating of A- 2
by S&P, P-2 by Moody's and "D-1-" by DCR is acceptable if such rating results
solely from a downgrading of any Liquidity Lender by S&P, Moody's or DCR , as
the case may be; provided further, however, the Company and DTAG each agrees to
notify each of the Dealers in writing promptly following its receipt of notice
or actual knowledge of the downgrade or potential downgrade of any Liquidity
Lender with respect to the identity of such Liquidity Lender and what action if
any the Company is taking under Section 5.9(a) of the Liquidity Agreement to
replace such Liquidity Lender; provided further, however, the Company agrees to
exercise its right under Section 5.9(a) of the Liquidity Agreement to replace
any Liquidity Lender whose credit rating on its short-term debt has been
withdrawn or downgraded by S&P, Moody's or DCR (if rated by DCR). Such ratings
were obtained by the Company with the understanding that S&P, Moody's and DCR
would continue to monitor the credit of the Company and make future adjustments
in such ratings to the extent warranted.

         (c) It will be a condition precedent to the initial issuance of any
Commercial Paper Notes and each subsequent issuance of Commercial Paper Notes
that the issuance of such Commercial Paper Notes will not cause the Company to
have a negative net worth. The Company will be responsible for monitoring its
net worth for purposes of this Section 7(c) and hereby agrees to notify each of
the Dealers promptly following its receipt of notice or actual knowledge that
the issuance of such Commercial Paper Notes will cause the Company to have a
negative net worth.

         (d) Prior to the sale of the Commercial Paper Notes, the Company and
DTAG shall approve in writing a copy of the Offering Materials, including the
Offering Memorandum.

         8. Delivery of and Payment for the Commercial Paper Notes. (a) On the
date of a proposed issuance of Commercial Paper Notes, the Company shall confer
with one or more of the Dealers as to the face or principal amount, maturities
and denominations thereof, the applicable interest rates or the discounts from
the face amounts, at which the Commercial Paper Notes are to be issued.

         (b) On any date on which Commercial Paper Notes are to be sold
hereunder, each Dealer shall notify the Company as soon as practicable but not
later than 12:00 noon (New York City time) on such day of the amount of
Commercial Paper Notes placed by such Dealer by that time on such day.

         (c) On any date on which Commercial Paper Notes are to be sold
hereunder, each Dealer shall notify the Depositary as soon as practicable, but
not later than 1:15 p.m. (New York City time) on such day of the amount of
Commercial Paper Notes placed by such Dealer by that time on such day.

         9. Indemnification. DTAG agrees to assume liability for and to
indemnify, protect, save and hold harmless each Dealer, each individual,
corporation, partnership, trust, association or other entity (each, a "Person")
controlling each Dealer within the meaning of the Act or the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), or any Affiliate of any such
Person or a Dealer and their respective officers, directors, shareholders,
partners, servants, trustees, employees and agents (all of such indemnified
entities hereinafter the "Indemnitees") from and against any and all losses,
liabilities, claims, damages, penalties, causes of action, suits, costs and
expenses (including, without limitation, reasonable attorneys' fees and
expenses) or judgments of whatever kind and nature, imposed upon, incurred by or
asserted against the Indemnitees, which are (x) based upon or arising under the
securities laws of the United States of America or of any state and any
regulation, rule or interpretation thereunder or thereof to the extent arising
from the transactions contemplated hereby, (y) based upon the inaccuracy of any
representation made or reaffirmed by DTAG or the Company or the material breach
of any agreement or covenant of DTAG or the Company contained herein or (z)
based upon any untrue statement or alleged untrue statement of a material fact
in the Offering Materials or in any information (whether oral or written) or
documents or made available by the Company to offerees of the Commercial Paper
Notes or any of their representatives, or the omission or alleged omission from
the Offering Materials or from any information (whether oral or written) or
documents furnished or made available by the Company or DTAG to offerees of the
Commercial Paper Notes or any of their representatives of a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; provided, however, that the obligation of
DTAG under this Section 9 shall not extend to any losses, liability, claims,
damages, penalties, causes of action, suits, costs and expenses which have been
finally judicially determined to have resulted from the Indemnitee's gross
negligence or willful misconduct in respect of clauses (x) or (y) as the case
may be. In case any action, suit or proceeding (each, a "Proceeding") is brought
against any Indemnitee, such Indemnitee shall notify DTAG in writing as soon as
practicable of the commencement thereof, DTAG will be entitled to participate
therein, and, to the extent that DTAG may elect by written notice delivered to
the Indemnitee, to assume the defense thereof, with counsel reasonably
satisfactory to such Indemnitee; provided that if the defendants in any such
Proceeding include both the Indemnitee and DTAG and the Indemnitee shall have
concluded that there may be legal defenses available to it which are different
from or additional to those available to DTAG, the Indemnitee shall have the
right to select separate counsel to assert such legal defenses and to otherwise
participate in the defense of such Proceeding on behalf of such Indemnitee. Upon
receipt of notice from DTAG to such Indemnitee of DTAG's election so to assume
the defense of such Proceeding and approval by the Indemnitee, DTAG will not be
liable to such Indemnitee for expenses incurred by the Indemnitee in connection
with the defense thereof (other than reasonable costs of investigation) unless
(i) the Indemnitee shall have employed separate counsel in connection with the
assertion of legal defenses in accordance with the proviso to the next preceding
sentence (it being understood, however, that DTAG shall not be liable for the
expenses of more than one separate counsel representing the Indemnitees who are
parties to such Proceeding), (ii) DTAG shall not have employed counsel
reasonably satisfactory to the Indemnitee to represent the Indemnitee within a
reasonable time after notice of commencement of the Proceeding or (iii)


                                      -12-
<PAGE>   13
DTAG has authorized in writing the employment of counsel for the Indemnitee.
DTAG agrees that, without any Indemnitee's prior written consent, it will not
settle, compromise or consent to the entry of any judgment in any Proceeding in
respect of which indemnification may be sought under the indemnification
provision of this Agreement (whether or not such Indemnitee is an actual or
potential party to such Proceeding), unless such settlement, compromise or
consent includes an unconditional release of each Indemnitee from all liability
arising out of such Proceeding.

         The Company agrees to assume liability for and to indemnify, protect,
save and hold harmless each of the Indemnitees from and against any and all
losses, liabilities, claims, damages, penalties, causes of action, suits, costs
and expenses (including, without limitation, reasonable attorneys' fees and
expenses) or judgments of whatever kind and nature, imposed upon, incurred by or
asserted against the Indemnitees, which are (x) based upon or arising under the
securities laws of the United States of America or of any state and any
regulation, rule or interpretation thereunder or thereof to the extent arising
from the transactions contemplated hereby, (y) based upon the inaccuracy of any
representation made or reaffirmed by the Company or the material breach of any
agreement or covenant of the Company contained herein or (z) based upon any
untrue statement or alleged untrue statement of a material fact in the Offering
Materials or in any information (whether oral or written) or documents furnished
or made available by the Company or DTAG to offerees of the Commercial Paper
Notes or any of their representatives, or the omission or alleged omission from
the Offering Materials or in any information (whether oral or written) or
documents furnished or made available by the Company to offerees of the
Commercial Paper Notes or any of their representatives of a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; provided, however, that the obligation of
the Company under this Section 9 shall not extend to any losses, liability,
claims, damages, penalties, causes of action, suits, costs and expenses which
have been finally judicially determined to have resulted from the Indemnitee's
gross negligence or willful misconduct in respect of clauses (x) or (y), as the
case may be. In case any Proceeding is brought against any Indemnitee, such
Indemnitee shall notify the Company in writing as soon as practicable of the
commencement thereof, the Company will be entitled to participate therein, and,
to the extent that the Company may elect by written notice delivered to the
Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory
to such Indemnitee; provided that if the defendants in any such Proceeding
include both the Indemnitee and the Company and the Indemnitee shall have
concluded that there may be legal defenses available to it which are different
from or additional to those available to the Company, the Indemnitee shall have
the right to select separate counsel to assert such legal defenses and to
otherwise participate in the defense of such Proceeding on behalf of such
Indemnitee. Upon receipt of notice from the Company to such Indemnitee of the
Company's election so to assume the defense of such Proceeding and approval by
the Indemnitee, the Company will not be liable to such Indemnitee for expenses
incurred by the Indemnitee in connection with the defense thereof (other than
reasonable costs of investigation) unless (i) the Indemnitee shall have employed
separate counsel in connection with the assertion of legal defenses in
accordance with the proviso to the next preceding sentence (it being understood,
however, that the Company shall


                                      -13-
<PAGE>   14
not be liable for the expenses of more than one separate counsel representing
the Indemnitees who are parties to such Proceeding), (ii) the Company shall not
have employed counsel reasonably satisfactory to the Indemnitee to represent the
Indemnitee within a reasonable time after notice of commencement of the
Proceeding or (iii) the Company has authorized in writing the employment of
counsel for the Indemnitee. The Company agrees that, without any Indemnitee's
prior written consent, it will not settle, compromise or consent to the entry of
any judgment in any Proceeding in respect of which indemnification may be sought
under the indemnification provision of this Agreement (whether or not such
Indemnitee is an actual or potential party to such Proceeding), unless such
settlement, compromise or consent includes an unconditional release of each
Indemnitee from all liability arising out of such Proceeding.

         The foregoing indemnities will also extend to any supplemental material
subsequently furnished in writing to any Dealer by DTAG or the Company for
distribution to purchasers or prospective purchasers during the term of this
Agreement.

         In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Section 9 is for
any reason held unavailable (otherwise than in accordance with the terms of this
Section 9), DTAG and the Company on the one hand, and any Indemnitee, on the
other hand, sought to be charged with any liability shall contribute to the
aggregate costs of satisfying such liability in the proportion of their
respective economic interests. For purposes of this Section 9, the "economic
interests" of DTAG and the Company shall be equal to the aggregate proceeds of
the Commercial Paper Notes issued in connection with this Agreement received by
the Company and the "economic interest" of any Indemnitee shall be equal to the
aggregate commissions and fees earned hereunder by the Dealer affiliated with
such Indemnitee.

         The obligations of DTAG and the Company under this Section 9 shall
survive any termination of this Agreement, in whole or in part.

         Notwithstanding anything to the contrary provided herein, neither DTAG
nor the Company will be liable in respect of any settlement of any pending or
threatened action if such settlement is effected without their written consent,
which consent shall not be withheld unless such settlement is unreasonable in
light of the claims or actions against, and defenses available to, the
Indemnitee.

         10. Fees and Expenses. Each Dealer shall be entitled to compensation
and reimbursement of expenses in the amounts mutually agreed upon (orally or in
writing) between the Company and such Dealer from time to time including,
without limitation, all of such Dealer's reasonable out-of-pocket expenses,
related to the printing and distribution of any Offering Materials and any
distribution expenses and the reasonable fees and disbursements of its counsel
in connection with the review and negotiation of this Agreement and the other CP
Program Documents.

the benefit of the holders of Commercial Paper Notes and each Dealer, that any
legal action, suit or proceeding against it arising out of this Agreement may be

process, summons, notices and documents out of any of the aforesaid courts by
mailing copies thereof by registered or certified air mail, postage prepaid, to

         15. Amendment and Termination; Successors; Counterparts. (a) The terms
of this Agreement shall not be waived, altered, modified, amended or

parties hereto. The Company may terminate this Agreement as to all parties or as

         18. Severability of Provisions. Any provision of this Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such

jurisdiction.

         19. Bankruptcy. Each Dealer covenants and agrees that, prior to the
date which is one year and one day after the payment in full of all Commercial
Paper Notes Outstanding, it will not institute against, or join any other Person
in instituting against, the Company, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings or other similar proceeding
under the laws of the United States or any state of the United States. In the
event that any Dealer takes action in violation of this Section 19, the Company
agrees, for the benefit of the Holders of the Commercial Paper Notes, that it
shall file an answer with the bankruptcy court or otherwise properly contest the
filing of such a petition by the Dealer against the Company or the commencement
of such action and raise the defense that such Dealer has agreed in writing not
to take such action and should be estopped and precluded therefrom and such
other defenses, if any, as its counsel advises that it may assert; and such
Dealer acting in violation of this Section 19


                                      -17-

Company to such Dealer pursuant to Section 9 hereof shall be payable in the
order and priority set forth in Section 2.01 and 5.02(b), as applicable, of the
Collateral Agreement. Such obligations shall be due and payable by the Company
only to the extent that the Company's Assets are sufficient to pay such
obligations. No claims of any Dealer arising under or in connection with the
Collateral Agreement are intended to be impaired or waived by this Section 20.
The agreement of each Dealer under this Section 20 shall survive termination of
this Agreement.

         21. Entire Agreement. This Agreement constitutes the entire agreement
among the parties hereto with respect to the matters covered hereby and
supersedes all prior agreements and understandings among the parties.

         22. Assignment. This Agreement may not be assigned by DTAG or the
Company without the prior written consent of each of the Dealers or by any
Dealer without the prior written consent of each of DTAG and the Company, and
any such assignment without such consent shall be null and void. Notwithstanding
the immediately preceding sentence, this Agreement may be assigned or
transferred by any of the Dealers to any Affiliate of such Dealer upon at least
30 days prior written notice to each of the Company and DTAG; provided, that,
the Dealer shall remain liable and responsible for its duties and obligations
hereunder if such assignment or transfer is to an Affiliate of such Dealer.

         23. Several Obligations. The Company acknowledges that the Dealers are
acting severally under this Agreement, and not jointly, and no Dealer shall have
any responsibility whatsoever for any purchase commitment or other undertaking
made by any other Dealer hereunder.

         Re:  Confidentiality Agreement

Ladies and Gentlemen:

         In order to induce Dollar Thrifty Funding Corp. (the "Company") and
Dollar Thrifty Automotive Group, Inc. ("DTAG") to provide us with certain
confidential and proprietary information concerning the Company and DTAG, and
the Company's assets, credit, liquidity and finances, the Company's business
relationships, various manufacturers and other persons, and any other
confidential and proprietary information provided by the Company or DTAG at any
time, in each case identified by DTAG or the Company as confidential and
proprietary (all of such information collectively referred to herein as the
"Confidential Information") for the sole purpose of and use by us in evaluating
whether to act or continue to act as a dealer in connection with the Company's
asset backed commercial paper program ("Transactions"), we hereby agree with the
Company and DTAG as follows:

         1.       Confidential Information shall not be disclosed by the
                  recipient without prior written permission of each of the
                  Company and DTAG except on a confidential basis to those
                  directors, officers, representatives and employees of the
                  recipient who are directly participating in, or engaged in the
                  evaluation of the proposed Transactions or persons in similar
                  positions with its affiliate who have a need to know. In
                  furtherance of such undertakings, the recipient agrees that it
                  will not duplicate or distribute to anyone, other than its
                  directors, officers, employees and authorized representatives
                  (including its accountants, attorneys and agents) who are
                  directly participating in the Transactions or persons in
                  similar positions with its affiliates who have a need to know,
                  any of the Confidential Information for any purpose, including
                  any competitive purpose, other than the Transactions.

<PAGE>   21
         2.       We shall cause our directors, officers, representatives, and
                  employees, to observe the terms of this Agreement to the same
                  extent that we are required to do so.

         3.       Notwithstanding any other provision in this Agreement, we and
                  our affiliates may disclose such information as may be
                  required (a) by court order, subpoena or similar process
                  issued by a court of competent jurisdiction or by a
                  governmental body, (b) in any report, statement or testimony
                  submitted to any municipal, state, federal or other regulatory
                  body having jurisdiction over such party or any of its
                  affiliates and required by such regulatory body to be so
                  disclosed, (c) in order to comply with any law, order,
                  regulation or ruling applicable to such party or any of its
                  affiliates, and we shall promptly inform the Company and DTAG
                  of our disclosure to any party pursuant to this paragraph 3
                  (other than disclosure of information to regulatory bodies in
                  the normal course of their regulatory oversight that is not
                  publicly available), or (d) in any court proceeding instituted
                  by or against Credit Suisse First Boston Corporation and its
                  affiliates (collectively, "CSFB") or Chase Securities Inc. or
                  its affiliates (collectively, "Chase") in furtherance of the
                  establishment of defenses available to CSFB or Chase, or (e)
                  to correct any untrue statements or errors in the Offering
                  Materials (as such term is defined in that certain Dealer
                  Agreement, dated March 4, 1998, among DTAG, the Company, as
                  issuer, and Credit Suisse First Boston Corporation and Chase
                  Securities Inc., each as a dealer thereto (the "Dealer
                  Agreement")).
