                  Custodian, enforceable against it in accordance with its
                  terms, except as enforcement of such terms may be limited by
                  bankruptcy, insolvency or similar laws affecting the
                  enforcement of creditors' rights generally and by the
                  availability of equitable remedies;

(iii)    Neither the  execution  and  delivery of this  Agreement,  the  delivery of  Receivables  to  Custodian,  the  issuance of the
                  Custodian  Certifications,  the consummation of the transactions  contemplated hereby or thereby, nor the fulfillment
                  of or compliance  with the terms and  conditions of this Agreement will conflict with or result in a breach of any of
                  the terms,  conditions  or  provisions  of  Custodian's  charter or bylaws or any  agreement or  instrument  to which
                  Custodian is now a party or by which it is bound, or constitute a default or result in an  acceleration  under any of
                  the foregoing, or result in the violation of any law, rule, regulation,  order, judgment or decree to which Custodian
                  or its  property  is subject;  except that no  representation  or  warranty  is made as to  compliance  with laws and
                  regulations,  other than those of the United States and the State of Illinois, relating to qualifications,  licensure
                  or regulation of custodians of receivables originated in states other than Illinois;

(iv)              Custodian does not believe, nor does it have any reason or
                  cause to believe, that it cannot perform each and every
                  covenant contained in this Agreement;

(v)               To Custodian's knowledge after due inquiry, there is no
                  litigation pending or threatened, which if determined
                  adversely to Custodian, would adversely affect the execution,
                  delivery or enforceability of this Agreement, or any






7








of the
                  duties or obligations of Custodian thereunder, or which would
                  have a material adverse effect on the financial condition of
                  Custodian;

(vi)              No consent, approval, authorization or order of any court or
                  governmental agency or body is required for the execution,
                  delivery and performance by Custodian of or compliance by
                  Custodian with this Agreement or the consummation of the
                  transactions contemplated hereby or thereby; except that no
                  representation or warranty is made as to consents, approvals,
                  authorizations or orders of any courts or governmental
                  agencies or bodies, other than those of the United States and
                  the State of Illinois, relating to qualifications, licensure

                  states other than Illinois;

(vii)             Upon written request of the Indenture Trustee, Custodian shall
                  take such steps as requested by the Indenture Trustee to
                  protect or maintain any interest in any Receivable; and

(viii)            The Custodian has not been notified by any party other than
                  the Originator, the Seller, the Trust and the Indenture
                  Trustee that any such third party claims an interest in the
                  Receivables or the Receivables Files nor is any such party
                  requesting the Custodian to act as a bailee with respect to
                  the Receivables or the Receivables Files.

                  Custodian makes no representations or warranties as to the
validity, legality, sufficiency, enforceability, perfection, genuineness or
prior recorded status of any of the documents contained in each Receivables File
or the collectability, insurability, effectiveness or suitability of any
Receivable.

Section 5.2. Charges and Expenses. The Seller will pay all fees of Custodian in
connection with the performance of its duties hereunder in accordance with
written agreements to be entered into from time to time between the parties
hereto and Custodian, including fees and expenses of counsel incurred by
Custodian in the performance of its duties hereunder; provided, however, that
(i) Custodian shall in no event acquire any lien upon any Receivable deposited
under this Agreement or the Purchase Agreement or the Sale and Servicing
Agreement, or any claim against any Receivables Holder by reason of the failure
of the Seller to pay any of such charges or expenses and (ii) in the event the
Seller fails to pay the fees and expenses of Custodian as set forth in such
written agreements, Custodian shall have no obligation to take actions or incur
costs in connection with this Agreement unless the Seller or another Person has
made adequate provision for payment of Custodian's fees and expenses. The Seller
shall indemnify the Custodian against payment of any documentary stamp taxes,
intangible taxes and other similar taxes, penalties and interest incurred in
connection with the Receivables and the transactions contemplated hereby.

Section 5.3. No Adverse Interests. Custodian covenants and warrants to the
Originator, the Seller, the Servicer, the Trust and the Indenture Trustee, that
as of the date of each Custodian Certification: (i) it holds no adverse
interest, by way of security or otherwise, in any Receivable; and (ii) the
execution of this Agreement and the creation of the custodial rela-





8









tionship hereunder does not create any interest, by way of security or otherwise, of
Custodian in or to any Receivable, other than Custodian's rights as custodian
hereunder.

Section 5.4. Inspections. Upon reasonable prior written notice to Custodian, the
Servicer, the Seller, the Indenture Trustee, the Trust and such Person's agents,
accountants, attorneys and auditors will be permitted during normal business
hours to examine Custodian's documents, records and other papers in possession
of or under the control of Custodian relating to the Receivables.

Section 5.5. Insurance. Custodian shall, at its own expense, maintain at all
times during the existence of this Agreement and keep in full force and effect,
(1) fidelity insurance, (2) theft of documents insurance, and (3) forgery
insurance subject to deductibles, all as is customary for amounts and with
insurance companies reasonably acceptable to the Servicer and the Indenture
Trustee. A certificate of the respective insurer as to each such policy or a
blanket policy for such coverage shall be furnished to the Servicer or the
Indenture Trustee, upon request, containing the insurer's statement or
endorsement that such insurance shall not terminate prior to receipt by such
party, by registered mail, of 10 days advance notice thereof.

Section 5.6. Limitation of Liability. Custodian assumes no obligation, and shall
be subject to no liability, under this Agreement, except for its negligence or
willful misconduct in the performance of the obligations and duties as are
specifically set forth herein. Custodian shall not be liable for any action or
non-action by it in reliance on advice of counsel believed by it in good faith
to be competent to give such advice. Custodian may rely and shall be protected
in acting upon any written notice, order, request, direction or other document
believed by it to be genuine and to have been signed or presented by the proper
party or parties.

Section 5.7. Indemnification. Servicer agrees to indemnify Custodian against,
and to hold it harmless from, any liabilities, and any related out-of-pocket
expenses, which it may incur in connection with this Agreement, the Sale and
Servicing Agreement, the Purchase Agreement or the Custodian Certifications,
other than any liabilities and expenses arising out of Custodian's negligence or
willful misconduct. The Custodian agrees to indemnify, defend and hold harmless
the Indenture Trustee against any liability to Noteholders and/or
Certificateholder arising out of the negligence or willful misconduct of the
Custodian (a) in the preparation or execution of any Custodian Certification or
(b) resulting in the loss of Receivables Files in the custody of the Custodian.
This indemnity shall include indemnification as to reasonable attorneys' fees
and costs, whether or not suit be brought, and including such fees and costs on
appeal. The Indenture Trustee shall give prompt written notice to the Custodian
of any claim for which indemnity is or may be sought and shall afford to the
Custodian the opportunity to defend such claim.

Section 5.8. Further Rights of Custodian. (a) If the Custodian is at any time
uncertain of its obligations hereunder, the Custodian, upon prior written notice
to the Indenture Trustee, the Trust, the Originator, the Seller and the
Servicer, may refrain from taking any action with respect to such matter until
such uncertainty is removed. If conflicting demands are made on the Custodian
with respect to any matter, the Indenture Trustee's demand shall control, except
during the period prior to the issuance of the Trustee's Custodian Certification
pursuant to Section 3.1 hereof, when the applicable Receivables Holder's demand
shall control and the Custo-





9









dian shall have the right to rely on such controlling demand. The Custodian
shall have the right in any such case to interplead any or
all of the documents contained in the Receivables Files in a court of competent
jurisdiction and, upon delivery thereof, shall have no further obligations
thereunder with respect to such documents.

(b)      The obligations of the Custodian shall be determined solely by the
         express provisions of this Agreement. No representation, warranty,
         covenant or obligation of the Custodian shall be implied with respect
         to this Agreement or the Custodian's service hereunder. Without
         limiting the generality of the foregoing statement, except as
         specifically required herein, the Custodian shall be under no
         obligation to inspect, review or examine the Receivables Files to
         determine that the contents thereof are complete, genuine, enforceable
         or appropriate for the represented purpose or that they have been
         actually recorded or filed in required offices or that they are other
         than what they purport to be on their face.

(c)      No provision of this Agreement shall require the Custodian to spend or
         risk its own funds or otherwise incur financial liability in
         performance of its duties under this Agreement unless, pursuant to
         Section 5.2 hereof, adequate provision has been made for the
         reimbursement of the Custodian's expenses hereunder.

successor custodian within 30 days, the Servicer shall appoint a successor
