         Receivable and all assets relating thereto, free and clear of any
         Liens. All such assets are transferred to the Purchaser without
         recourse to MFC except as described herein. The purchases of such
         assets by the Purchaser constitute valid and true sales for
         consideration (and not merely a pledge of such assets for security
         purposes) and the contributions of such assets received by the
         Purchaser constitute valid and true transfers for consideration, each
         enforceable against creditors of MFC, and no such assets shall
         constitute property of MFC.

                  Ownership of MFC. All of the membership interests of MFC are
         owned, either directly or indirectly, by the Contributing Subsidiaries
         or their respective successors or Affiliates.

                             COVENANTS OF THE SELLER

         Liens in Force. The Financed Vehicle securing each Receivable shall not
be released by the Seller in whole or in part from the security interest granted
under the related Receivable, except upon payment in full of the Receivable or
as otherwise contemplated herein

                                       7
<PAGE>

or the Transaction Documents and the Seller shall not take or permit any action
inconsistent with the foregoing.

         No Impairment. The Seller shall do nothing to impair the rights of the
Purchaser or the Secured Parties in the Receivables, the Dealer Agreements, the
Dealer Assignments, the Insurance Policies or any other property or interest
comprising the Other Conveyed Property.

         No Amendments. The Seller shall not take or permit any action to extend
or otherwise amend the terms of any Receivable, except in accordance with the
Transaction Documents.

         Restrictions on Liens. The Seller shall not: (i) create or incur or
agree to create or incur, or consent to cause (upon the happening of a
contingency or otherwise) the creation, incurrence or existence of any Lien or
restriction on transferability of the Receivables or of any Other Conveyed
Property except for the Lien in favor of the Purchaser and the Collateral Agent
as assignee thereof, and the restrictions on transferability imposed by this
Agreement or (ii) sign or file under the Uniform Commercial Code of any
jurisdiction any financing statement or sign any security agreement authorizing
any secured party thereunder to file such financing statement, with respect to
the Receivables or to any Other Conveyed Property, except in each case any such
instrument solely securing the rights and preserving the Lien of the Purchaser
and the Collateral Agent as assignee thereof. The Seller will take no action to
cause any Receivable to be evidenced by an instrument (as such term is defined
in the relevant UCC).

         Preservation of Collateral. MFC will do, execute, acknowledge and
deliver, or cause to be done, executed, acknowledged and delivered, such
instruments of transfer or take such other steps or actions as may be necessary,
or required by the Purchaser or the Collateral Agent or the Agent, to effect the
Conveyance, to perfect the security interest granted in the Receivables and the
Other Conveyed Property to the Collateral Agent on behalf of the Secured
Parties, to ensure that such Conveyance and security interest ranks prior to all
other Liens and to preserve the priority of such Conveyance and security
interest and the validity and enforceability thereof.

         Preservation of Existence. MFC shall observe all procedures required by
its organizational documents and operating agreement and preserve and maintain
its existence, rights, franchises and privileges in the jurisdiction of
organization, and qualify and remain qualified in good standing in each
jurisdiction where the failure to preserve and maintain such existence, rights,
franchises, privileges and qualifications would materially adversely affect (1)
the interests hereunder of the Collateral Agent or any Affected Person, (2) the
collectibility of any Receivable or (3) its ability to perform its obligations
hereunder or under any of the other Transaction Documents.

         Separate Existence. MFC shall take all reasonable steps (including,
without limitation, all steps that the Agent may from time to time reasonably
request) to maintain MFC's identity as a separate legal entity from the
Purchaser and to make it manifest to third parties that MFC is an entity with
assets and liabilities distinct from those of the Purchaser and each other
Affiliate thereof. Without limiting the generality of the foregoing, MFC shall:

                                       8
<PAGE>

                  account for and manage its liabilities separately from those
         of the Purchaser, including, without limitation, payment of all payroll
         and other administrative expenses and taxes from its own assets (it
         being understood, however, that Borrower is a "disregarded entity" for
         tax purposes);

                  maintain its assets separately from the Purchaser;

                  maintain offices through which its business is conducted
         separate from those of the Purchaser (provided that, to the extent that
         the Servicer and any of its Affiliates have offices in the same
         location, there shall be a fair and appropriate allocation of overhead
         costs and expenses among them, and each such entity shall bear its fair
         share of such expenses);

                  not commingle its funds with those of the Purchaser except to
         the extent contemplated herein or in the Receivables Financing
         Agreement, or use its funds for other than the MFC's uses; and

                  ensure that any financial reports required of MFC shall comply
         with GAAP and shall be issued separately from, but may be consolidated
         with, any reports prepared by the Purchaser.

         Documents. MFC shall comply with each of the terms of the Transaction
Documents to which it is party (in any capacity) and shall not cancel or
terminate any of the Transaction Documents to which it is party or subject (in
any capacity), or consent to or accept any cancellation or termination of any of
such agreements, or amend or otherwise modify any term or condition of any of
the Transaction Documents to which it is party or subject (in any capacity) or
give any consent, waiver or approval under any such agreement, or waive any
default under or breach of any of the Transaction Documents to which it is party
(in any capacity) or take any other action under any such agreement not required
by the terms thereof, unless (in each case) the Agent shall have consented
thereto.

         Sales, Liens, Etc. Against Membership Interests. The Seller shall not,
except as otherwise provided herein or in the Membership Pledge Agreement, sell,
assign (by operation of law or otherwise) or otherwise dispose of, or create or
suffer to exist, any lien upon or with respect to, its membership interests in
the Purchaser.

                                   REPURCHASES

         Repurchase Upon Breach of Warranty. Upon the occurrence of a Repurchase
Event, MFC shall (unless the breach which is the subject of such Repurchase
Event shall have been cured in all material respects by the last day of the
second Determination Date after such breach), repurchase the Receivable or
Receivables affected thereby from the Purchaser and, simultaneously with the
repurchase of the Receivable, MFC shall deposit the Purchase Amount in full,
without deduction or offset, to the Collection Account, pursuant to Section 8.18
of the Receivables Financing Agreement. The provisions of this Section 5.1 are
intended to grant the Collateral Agent and the Agent a direct right against MFC
to demand performance hereunder,

                                       9
<PAGE>

and in connection therewith, MFC waives any requirement of prior demand against
Purchaser with respect to such repurchase obligation. Any such repurchase shall
take place in the manner specified in Section 8.7 of the Receivables Financing
Agreement. Notwithstanding any other provision of this Agreement or the
Receivables Financing Agreement to the contrary, the obligation of MFC under
this Section shall not terminate upon a termination of MFC as Servicer under the
Receivables Financing Agreement and shall be performed in accordance with the
terms hereof notwithstanding the failure of the Servicer or Purchaser to perform
any of their respective obligations with respect to such Receivable under the
Receivables Financing Agreement.

         Reassignment of Purchased Receivables. Upon deposit in the Collection
Account of the Purchase Amount of any Receivable repurchased by MFC under
Section 5.1 hereof, Purchaser (at MFC's expense) shall take such steps as may be
reasonably requested by MFC in order to assign to MFC all of Purchaser's and the
Collateral Agent's right, title and interest in and to such purchased Receivable
and all security and documents and all Other Conveyed Property conveyed to
Purchaser and the Collateral Agent directly relating thereto, without recourse,
representation or warranty, except as to the absence of Liens created by or
arising as a result of actions of Purchaser or the Collateral Agent. Such
assignment shall be a sale and assignment outright, and not for security. If,
following the reassignment of a Receivable, in any enforcement suit or legal
proceeding, it is held that MFC may not enforce any such Receivable on the
ground that it shall not be a real party in interest or a holder entitled to
enforce the Receivable, Purchaser and the Collateral Agent shall, at the expense
of MFC, take such steps as MFC deems reasonably necessary to enforce the
Receivable, including bringing suit in Purchaser's or in the Collateral Agent's
name.

         Waivers. No failure or delay on the part of Purchaser, or the
Collateral Agent as assignee of Purchaser, in exercising any power, right or
remedy under this Agreement shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power, right or remedy preclude any other
or future exercise thereof or the exercise of any other power, right or remedy.

                              CONDITIONS PRECEDENT

         Conditions Precedent to each Sale. Each sale and/or contribution of
Receivables shall be subject to the conditions precedent that:

                  the Effective Date under the Receivables Financing Agreement
         shall have occurred and, unless the Receivables are to be contributed
         to the Purchaser, the conditions to the making of the related Advance
         pursuant to Section 7.2 and/or 7.3 (as the case may be) of the
         Receivables Financing Agreement shall have been satisfied or waived.

                  the Seller shall, to the extent required by Section 8.2 of the
         Receivables Financing Agreement, have deposited in the Collection
         Account all collections received after the Relevant Cutoff Date with
         respect to the Receivables to be sold on such Transfer Date;

                                       10
<PAGE>

                  the Seller shall take any action (including, but not limited
         to, the filing of appropriate UCC financing statements) required to
         perfect the ownership interest of the Purchaser in the Receivables and
         the Other Conveyed Property (provided, however, that the Seller shall
         make such filings as promptly as possible and in no event later than
         the third Business Day following the respective Receivables Transfer
         Date and shall promptly provide to each of the Purchaser and the
         Collateral Agent and the Agent a copy of a stamped acknowledgement copy
         thereof); and

                  such sale or contribution shall be reflected on the books and
         records of the Borrower pursuant to Section 2.2.

                                  MISCELLANEOUS

         Liability of Seller. Seller shall be liable in accordance herewith only
to the extent of the obligations in this Agreement specifically undertaken by
the Seller and the representations and warranties of the Seller.

         Merger or Consolidation of the Seller. Any corporation or other entity
(i) into which the Seller may be merged or consolidated, (ii) resulting from any
merger or consolidation to which the Seller is a party or (iii) succeeding to
the business of the Seller shall execute an agreement of assumption to perform
every obligation of the Seller under this Agreement and, whether or not such
assumption agreement is executed, shall be the successor to the Seller hereunder
(without relieving the Seller of its responsibilities hereunder, if it survives
such merger or consolidation) without the execution or filing of any document or
any further action by any of the parties to this Agreement; provided, however,
that any such merger or consolidation is subject in all respects to the
restrictions set forth in its articles of incorporation and the consent of the
Agent (which consent shall not be unreasonably withheld).

         Limitation on Liability of the Seller and Others. The Seller and any
director, officer, employee or agent thereof may rely in good faith on the
advice of counsel or on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising under this Agreement.
The Seller shall not be under any obligation to appear in, prosecute or defend
any legal action that is not incidental to its obligations under this Agreement
or its Transaction Documents.

         Amendment.

                  This Agreement may be amended by the Seller and Purchaser
         (with the consent of the Agent) without the consent of the Collateral
         Agent (i) to cure any ambiguity (ii) to correct any provisions in this
         Agreement or (iii) at any such time as the Receivable Financing
         Agreement has been terminated and no longer in effect; provided,
         however, that such action shall not adversely affect the interests of
         any Secured Party.

                  This Agreement may also be amended from time to time by the
         Seller and Purchaser with the consent of the Collateral Agent and the
         Agent, in accordance with the Receivables Financing Agreement.

the event of the bankruptcy, reorganization, arrangement, insolvency or
liquidation proceeding, or other proceeding under any federal or state
bankruptcy or similar law, or the occurrence of another similar event, of, or
with respect to, the Seller. In the event that such conveyance is determined to

security interest in all of the Seller's right, title and interest in and to the
Receivables and the Other Conveyed Property conveyed pursuant to Section 2.1
