                          ADMINISTRATION AND COLLECTION

         SECTION 2.1. Reconciliation of Monthly Report.

                  (a) No later than 9:00 A.M. New York time on the third
Business Day following the end of each Collection Period, the Servicer shall
send to the Backup Servicer an electronic file, detailing the Collections
received during the prior Collection Period and all other information relating
to the Loans and the Contracts as may be necessary for the complete and correct
completion of the Monthly Report (the "Servicer's Data File"). Such electronic

                                        2


<PAGE>



be in the form and have the specifications as may be agreed to between the
Servicer and the Backup Servicer from time to time. The Backup Servicer shall,
within one (1) Business Day of the receipt thereof, load the Servicer's Data
File and confirm that it is in readable form. If the Backup Servicer determines
that the Servicer's Data File is not in readable form, the Backup Servicer shall
immediately upon discovery thereof notify the Servicer and the Deal Agent by
telephone, and upon such notification, the Servicer shall prepare and send a
replacement Servicer's Data File to the Backup Servicer satisfying the Backup
Servicer's specifications, for receipt by the Backup Servicer on the next
Business Day.

                  (b) No later than the end of the second Business Day prior to
each Determination Date, the Servicer shall furnish to the Backup Servicer the
Monthly Report related to the prior Collection Period together with all other
information necessary for preparation of such Monthly Report and necessary to
determine the application of Collections as provided in the Loan Agreement. The
Backup Servicer shall review the information contained in the Monthly Report
against the information on the Servicer's Data File, on an Aggregate Basis. No
later than three (3) Business Days after the Backup Servicer's receipt of each
Monthly Report, the Backup Servicer shall notify the Servicer and the Deal Agent
of any inconsistencies between the Monthly Report and the information contained
in the Servicer's Data File; provided, however, in the absence of a
reconciliation, the Monthly Report shall control for the purpose of calculations
and distributions with respect to the related Payment Date. If the Backup
Servicer and the Servicer are unable to reconcile discrepancies with respect to
a Monthly Report prior to the related Payment Date, the Servicer shall cause a
firm of independent accountants, at the Servicer's expense, to audit the Monthly
Report and, prior to the third Business Day, but in no event later than the
fifth calendar day, of the following month, reconcile the discrepancies. The
effect, if any, of such reconciliation shall be reflected in the Monthly Report
for such next Payment Date. The Backup Servicer shall only review the
information provided by the Servicer in the Monthly Report and in the Servicer's
Data File and its obligation to report any inconsistencies shall be limited to
those determinable from such information.

                  (c) The Backup Servicer and the Servicer shall attempt to
reconcile any such inconsistencies and/or to furnish any omitted information and
the Servicer shall amend the Monthly Report to reflect the results of the
reconciliation or to include any omitted information.

                  (d) The Servicer shall provide monthly, or as otherwise
requested, to the Backup Servicer, or its agent, information on the Loans and
related Contracts sufficient to enable the Backup Servicer to assume the
responsibilities as Successor Servicer under the Loan Agreement and service and
collect the Loans and related Contracts.

                  (e) The Servicer shall provide the Backup Servicer with any
and all updates to the master file data layout and copy book information
necessary due to system changes or modifications, which may require changes to
the Backup Servicer's applications necessary to read the Servicer's Data File.

         SECTION 2.2. Review and Verification.

                  (a) Notwithstanding anything in Section 2.1 to the contrary,
on or before the end of the second Business Day prior to each Determination
Date, the Servicer and the Deal



                                        3

Agent shall provide sufficient data to the Backup Servicer to allow the Backup
Servicer to review and to verify the mathematical accuracy of the Monthly Report
on an Aggregate Basis related thereto and determine the following:

                           (i) that such Monthly Report is complete on its face;

                           (ii) that the amounts credited to and withdrawn from
                  the Collection Account and the balance of such account, as set
                  forth in the records of the Collateral Agent are the same as
                  the amount set forth in the Monthly Report; and

                           (iii) that the amounts credited to and withdrawn from
                  the Reserve Account and the balance of such account, as set
                  forth in the records of the Collateral Agent are the same as
                  the amount set forth in the Monthly Report.

                  (b) The Backup Servicer shall, on or before the Determination
Date with respect to any Collection Period, verify the mathematical accuracy of
the Monthly Report in its entirety, which shall include but not be limited to
the following:

                           (i) the amount of the related distribution allocable
                  to principal;

                           (ii) the amount of the related distribution allocable
                  to interest;

                           (iii) the amount of the related distribution payable
                  out of the Reserve Account;

                           (iv) the Aggregate Outstanding Eligible Loan Net
                  Balance, the Aggregate Outstanding Eligible Loan Balance and
                  the aggregate Outstanding Balance of all Eligible Contracts as
                  of the close of business on the last day of the preceding
                  Collection Period;

                           (v) outstanding Capital;

                           (vi) the amount of the Servicing Fee paid to the
                  Servicer with respect to the related Collection Period and/or
                  due but unpaid with respect to such Collection Period or prior
                  Collection Periods, as the case may be;

                           (vii) the total amount of Collections for the related
                  Collection Period; and

                           (viii) the aggregate Release Price for the Ineligible
                  Loans and the aggregate Released Contract Price for the
                  Ineligible Contracts, if any, that was paid in such period.

                  (c) The Backup Servicer shall provide written notice to the
Deal Agent with respect to whether there are any inconsistencies or deficiencies
with respect to its review and verification set forth in paragraphs (a) and (b)
above and, if any, shall provide a description thereof as set forth in Section
2.10 hereof. In the event of any discrepancy between the information set forth
in subparagraphs (a) and (b) above, as calculated by the Servicer, from that




                                        4


<PAGE>



determined or calculated by the Backup Servicer, the Backup Servicer shall
promptly notify the Servicer and, if within five (5) days of such notice being
provided to the Servicer, the Backup Servicer and the Servicer are unable to
resolve such discrepancy, the Backup Servicer shall promptly notify the Deal
Agent of such discrepancy.

                           (i) Other than as specifically set forth elsewhere in
                  this Agreement, the Backup Servicer shall have no obligation
                  to supervise, verify, monitor or administer the performance of
                  the Servicer and shall have no duty, responsibility,
                  obligation, or liability (collectively "Liability") for any
                  action taken or omitted by the Servicer.

                           (ii) The Backup Servicer shall consult with the
                  Servicer as may be necessary from time to time to perform or
                  carry out the Backup Servicer's obligations hereunder,
                  including the obligation, if requested in writing by the Deal
                  Agent, to succeed within thirty (30) days to the duties and
                  obligations of the Servicer pursuant to Section 2.3.

                           (iii) Except as otherwise provided in this Agreement,
                  the Backup Servicer may accept and reasonably rely on all
                  accounting, records and work of the Servicer without audit,
                  and the Backup Servicer shall have no Liability for the acts
                  or omissions of the Servicer or for the inaccuracy of any data
                  provided, produced or supplied by the Servicer. If any error,
                  inaccuracy or omission (collectively, "Errors") exists in any
                  information received from the Servicer, and such Errors should
                  cause or materially contribute to the Backup Servicer making
                  or continuing any Errors (collectively, "Continued Errors"),
                  the Backup Servicer shall have no Liability for such Continued
                  Errors; provided, however, that this provision shall not
                  protect the Backup Servicer against any Liability which would
                  otherwise be imposed by reason of willful misfeasance, bad
                  faith or gross negligence in discovering or correcting any
                  Error or in the performance of its duties hereunder or under
                  the Loan Agreement. In the event the Backup Servicer becomes
                  aware of Errors or Continued Errors which, in the opinion of
                  the Backup Servicer impairs its ability to perform its
                  services hereunder, the Backup Servicer may, with the prior
                  consent of the Deal Agent, undertake to reconstruct and
                  reconcile such data as it deems appropriate to correct such
                  Errors and Continued Errors and prevent future Continued
                  Errors. The Backup Servicer shall be entitled to recover its
                  costs thereby expended from the Servicer.

                           (iv) The Backup Servicer and its officers, directors,
                  employees and agents shall be indemnified by the Servicer from
                  and against all claims, damages, losses or expenses reasonably
                  incurred by the Backup Servicer (including reasonable
                  attorney's fees and expenses) arising out of claims asserted
                  against the Backup Servicer on any matter arising out of this
                  Agreement to the extent the act or omission giving rise to the
                  claim accrues before the Assumption Date, except for any
                  claims, damages, losses or expenses arising from the Backup
                  Servicer's own willful misfeasance, bad faith or gross
                  negligence. The obligations of the Servicer under this Section
                  shall survive the termination of this Agreement and the
                  earlier resignation or removal of the Backup Servicer.

                           (v) To the extent the Backup Servicer requires any
                  information, supplementary reports or data that is to be
                  provided to it pursuant to the Transaction Documents in order
                  to complete its verification duties, the Backup Servicer's

Termination Event at a time after the Assumption Date, and the Deal Agent and
any Liquidity Agent may conduct such review, with prior written notice but
otherwise without limitation, at the Servicer's expense if the Servicer

shall be $10,000,000 instead of $5,000,000), 6.11(j), 6.11(l), 9.2, 10.1(m),
11.2 (provided that the Backup Servicer shall be liable under Section 11.2(a) of
the Loan Agreement as to action taken by it as Successor Servicer) and 14.12.

         SECTION 2.4. Servicing and Retention of Servicer.

                  (a) Subject to early termination of the Backup Servicer due to
the occurrence of a Backup Servicer Event of Default, or pursuant to Article 4,
or as otherwise provided in this Section 2.4, on and after the Assumption Date,
the Backup Servicer shall be responsible for the servicing, administering,
managing and collection of the Loans and Contracts in accordance herewith and
the Loan Agreement.

                  (b) In the event of a Backup Servicer Event of Default, the
Deal Agent shall have the right to terminate the Backup Servicer as Successor
Servicer and Backup Servicer hereunder. Upon the termination or resignation of
the Backup Servicer hereunder, the Deal Agent shall have the right to appoint a
successor Backup Servicer (the "Successor Backup Servicer") and enter into a
backup servicing agreement with such Successor Backup Servicer at such time and
exercise all of its rights under Section 6.12(a) of the Loan Agreement;
provided, however, that if such termination or resignation of the Backup
Servicer occurs prior to the Assumption Date, the appointment of the Successor
Backup Servicer shall be mutually acceptable to Credit Acceptance and the Deal
Agent. Such backup servicing agreement shall specify the duties and obligations
of the Successor Backup Servicer, and all references herein and in the Loan
Agreement to the Backup Servicer shall be deemed to refer to such Successor
Backup Servicer.

                  (c) Except as provided in Section 4.3 hereof, the Backup
Servicer shall not resign from the obligations and duties imposed on it by this
Agreement or the Loan Agreement, as successor servicer or as Backup Servicer, as
applicable, except upon a determination that by reason of a change in legal
requirements, the performance of its duties hereunder or under the Loan
Agreement would cause it to be in violation of such legal requirements in a
manner which would have a material adverse effect on the Backup Servicer, and
the Deal Agent does not elect to waive the obligations of the Backup Servicer to
perform the duties which render it legally unable to act or to delegate those
duties to another Person. Any such determination permitting the resignation of
the Backup Servicer pursuant to this Section 2.4(c) shall be evidenced by an
opinion of counsel to such effect delivered and acceptable to the Deal Agent. No
resignation of the Backup Servicer shall become effective until an entity
reasonably acceptable to the Deal Agent and the Required Investors shall have
assumed the responsibilities and obligations of the Backup Servicer.

                  (d) Any Person: (i) into which the Backup Servicer may be
merged or consolidated; (ii) resulting from any merger or consolidation to which
the Backup Servicer shall be a party; (iii) which acquires by conveyance,
transfer or lease substantially all of the assets of the Backup Servicer; or
(iv) succeeding to the business of the Backup Servicer, in any of the foregoing
cases shall execute an agreement of assumption to perform every obligation of
the Backup Servicer under this Agreement and the Loan Agreement, whether or not
such assumption agreement is executed, shall be the successor to the Backup
Servicer under this Agreement and



                                        7

the Loan Agreement without the execution or filing of any paper or any further
act on the part of any of the parties to this Agreement or the Loan Agreement,
anything herein or therein to the contrary notwithstanding; provided, however,
that nothing contained herein or therein shall be deemed to release the Backup
Servicer from any obligation hereunder or under the Loan Agreement.

                  (e) Following the Assumption Date, the Backup Servicer shall
be required to deliver to the Deal Agent on or before one hundred twenty (120)
days after the end of the Backup Servicer's fiscal year, with respect to such

delivered under (e) above, a report certified by the chief financial officer of
the Backup Servicer, certifying that no Backup Servicer Event of Default and no
event which, with the giving of notice or the passage of time, would become a
Backup Servicer Event of Default has occurred and is continuing or, if any such
Backup Servicer Event of Default or other event has occurred and is continuing,
such a Backup Servicer Event of Default has occurred and is continuing, the
action which the Backup Servicer has taken or proposes to take with respect

         SECTION 2.5. Servicing Duties of the Backup Servicer. On and after the
Assumption Date:


                  (a) The Backup Servicer shall take or cause to be taken all
such action as may be necessary or advisable to collect all amounts due under
the Loans and Contracts from time to time, all in accordance with applicable
laws, rules and regulations, with reasonable care and diligence, and in
accordance with the Collection Guidelines. There shall be no recourse to the
Backup Servicer with regard to the Loans and Contracts. The Backup Servicer
shall hold in trust for the Collateral Agent all records which evidence or
relate to all or any part of the Collateral. In the event that a Successor
Backup Servicer is appointed, the outgoing Backup Servicer shall deliver to the
Successor Backup Servicer and the Successor Backup Servicer shall hold in trust
for the Collateral Agent all records which evidence or relate to all or any part
of the Collateral.

                  (b) The Backup Servicer shall as soon as practicable upon
demand, deliver to the Deal Agent all records in its possession which evidence
or relate to indebtedness of an Obligor which is not a Loan or Contract.

                  (c) The Backup Servicer shall remit to the Collection Account
within one (1) Business Day of receipt all Collections with respect to cleared
funds, and within three (3) Business Days of receipt Collections in all other
cases.

                  (d) In addition to the obligations of the Backup Servicer
under this Agreement, the Backup Servicer shall perform all of the obligations
of the Servicer as servicer under the Loan Agreement, except as set forth in
Section 2.3(b) hereof. Without limiting the foregoing and anything provided for
herein, the Backup Servicer shall perform the following in substantially the
same manner and level at which Credit Acceptance performs such on the date

delinquent and charged-off accounts; (c) insurance monitoring and the making of
claims with respect thereto; (d) creating

holdback payments; (h) inventory management; (i) maintenance of lock-box
accounts; (j) electronic skip tracing; and (k) document storage and title
maintenance.

         SECTION 2.6. Other Obligations of the Backup Servicer and Servicer.

                  (a) In order to ensure preparedness to carry out the
Service-Related Activities, the Backup Servicer agrees that immediately upon
execution of this Agreement, it will begin to formulate a contingency plan
designed to execute a transition of the Service-Related Activities from Credit
Acceptance.

                  (b) [Reserved]

                  (c) No later than the 10th day of each calendar month until
the earlier of the Assumption Date or the termination of this Agreement, Credit
Acceptance shall provide a Live Data File (as defined below) transmission to the
Backup Servicer, which shall include the Loan and Contract master file, the
transaction history file and all other files necessary to carry out the
Service-Related Activities received in connection herewith (the "Live Data
Files"). The Backup Servicer shall convert the Live Data Files to its internal
systems, and no later than five (5) Business Days after the receipt thereof,
shall confirm in writing to Credit Acceptance the accuracy and completeness of
the conversion; provided, however, that such confirmation shall not be deemed to
apply to the accuracy of the Live Data Files as provided by Credit Acceptance,
but shall be deemed only to apply to the accuracy of the conversion of the Live
Data Files to the Backup Servicer's internal systems. In the event of any
changes in format with respect to either Credit Acceptance or the Backup
Servicer, Credit Acceptance and the Backup Servicer shall coordinate with each
other for the replacement of the data files with files in the correct format,
modified accordingly. To verify that Live Data Files have been accurately
converted to the Backup Servicer's internal servicing system, the Backup
Servicer will provide Credit Acceptance with such reports as are mutually agreed
upon by Credit Acceptance and the Backup Servicer from time to time. Credit
Acceptance reserves the right to review converted data on the Backup Servicer's
system either by performing an onsite review of the Backup Servicer's systems
or, at Credit Acceptance's sole expense, by having remote access to the Backup
Servicer's systems.

                  (d) In connection with the Backup Servicer assuming the
obligations of Servicer hereunder and under the Loan Agreement, Credit
Acceptance agrees that it shall: (i) promptly make available to the Backup
Servicer access to all records and information in the possession of Credit
Acceptance related to the Loans and the Contracts as may be necessary or
reasonably requested by the Backup Servicer in connection with the performance
of the Backup Servicer's obligations hereunder and thereunder; and (ii)
cooperate in good faith with the Backup Servicer and the Deal Agent in
connection with any transition of the servicing of the Loans and Contracts to
the Backup Servicer.

         SECTION 2.7. Servicing Compensation. As compensation for the
performance of its obligations under this Agreement and with respect to the Loan
Agreement, the Backup Servicer is entitled to: (i) prior to the Assumption Date,
the Backup Servicing Fee and (ii) after the




                                       9


<PAGE>




Assumption Date, the sum of: (A) the Servicing Fee, (B) any Repossession
Expenses, (C) any Reliening Expenses and (D) any Transition Expenses.

         SECTION 2.8. Collateral Agent's Rights. At any time following the
Assumption Date:

                  (a) The Collateral Agent or the Backup Servicer may direct
that payment of all amounts payable under any Loans or Contracts be made
directly to the Backup Servicer, the Collateral Agent or its designee.

                  (b) The Servicer shall, (unless otherwise directed by the
Collateral Agent) (i) assemble all of the records relating to the Collateral and
shall make the same available to the Backup Servicer (or the Collateral Agent if
so directed by the Collateral Agent) at a place selected by the Backup Servicer
or the Collateral Agent, as applicable; provided, however, that the Servicer
will be entitled to retain copies of all records provided pursuant to this
Section 2.8(b), and (ii) segregate all cash, checks and other instruments
received by it from time to time constituting Collections in a manner acceptable
to the Collateral Agent and shall, promptly upon receipt but no later than one
(1) Business Day after receipt, remit all such cash, checks and instruments,
duly endorsed or with duly executed instruments of transfer, as directed by the
Collateral Agent or the Backup Servicer.

                  (c) Credit Acceptance hereby authorizes the Collateral Agent
and the Backup Servicer to take any and all steps in Credit Acceptance's name
and on behalf of Credit Acceptance necessary or desirable, in the determination
of the Backup Servicer or the Collateral Agent acting in "good faith" (as such
term is defined in Article 9 of the UCC), to collect all amounts due under any
and all of the Loans, including, without limitation, endorsing Credit
Acceptance's name on checks and other instruments representing Collections and
enforcing the Loans and Contracts; provided, however, that the Collateral Agent
shall not have an affirmative obligation to carry out such duties.

         SECTION 2.9. Liability of the Backup Servicer; Standard of Care.

                  (a) The Backup Servicer shall not be liable for its actions or
omissions hereunder except for its negligence, willful misconduct or breach of
this Agreement not caused by another party to this Agreement, or for any
recitals, statements, representations or warranties made expressly by the Backup
Servicer.

                  (b) The Backup Servicer shall indemnify, defend and hold
harmless the Servicer and its respective officers, directors, agents and
employees from and against any and all costs, expenses, losses, claims, damages
and liabilities to the extent that such cost, expense, loss, claim, damage or
liability arose out of, or was imposed upon the Servicer through the Backup
Servicer's breach of this Agreement, the willful misfeasance, bad faith or
negligence of the Backup Servicer in the performance of its duties under this
Agreement or by reason of reckless disregard of its obligations and duties under
this Agreement.

                  (c) The Servicer shall indemnify, defend and hold harmless the
Backup Servicer and its respective officers, directors, agents and employees
from and against any and all costs, expenses, losses, claims, damages and
liabilities to the extent that such cost, expense, loss, claim, damage or
liability arose out of, or was imposed upon the Backup Servicer through the



                                       10



<PAGE>



Servicer's breach of this Agreement, the willful misfeasance, bad faith or
negligence of the Servicer in the performance of its duties under this Agreement
or by reason of reckless disregard of its obligations and duties under this
Agreement.

                  (d) The Backup Servicer may accept and reasonably rely on all
accounting and servicing records and other documentation provided to the Backup
Servicer by or at the direction of the Servicer, including documents prepared or
maintained by any originator, or previous servicer, or any party providing
services related to the Loans or Contracts (collectively, the "Third Party").
The Servicer agrees to indemnify (subject to the limitation provided in
subsection (e) below) and hold harmless the Backup Servicer, its respective
officers, employees and agents against any and all claims, losses, penalties,
fines, forfeitures, legal fees and related costs, judgments, and any other
costs, fees and expenses that the Backup Servicer may sustain in any way related
to the negligence or misconduct of any Third Party with respect to the Loans or
Contracts. The Backup Servicer shall have no Liability for the acts or omissions
of any such Third Party or for the inaccuracy of any data provided, produced or
supplied by such Third Party. If any Error exists in any information provided to
the Backup Servicer and such Errors cause or materially contribute to the Backup
Servicer making a Continuing Error, the Backup Servicer shall have no liability
for such Continued Errors; provided, however, that this provision shall not
protect the Backup Servicer against any liability which would otherwise be
imposed by reason of willful misfeasance, bad faith or gross negligence in
discovering or correcting any error or in the performance of its duties
contemplated herein.

                  In the event the Backup Servicer becomes aware of Errors
and/or Continued Errors which, in the opinion of the Backup Servicer, impair its
ability to perform its services hereunder, the Backup Servicer shall promptly
notify the Servicer and the Deal Agent of such Errors and/or Continued Errors.
With the prior consent of the Servicer and the Deal Agent, the Backup Servicer
may undertake to reconstruct any data or records appropriate to correct such
Errors and/or Continued Errors and to prevent future Continued Errors. The
Backup Servicer shall be entitled to recover its costs thereby expended from the
Servicer.

                  (e) Indemnification under this Section shall include, without
limitation, reasonable fees and expenses of counsel (including in-house counsel)
and expenses of litigation. If the indemnifying party has made any indemnity
payments pursuant to this Section and the recipient thereafter collects any of
such amounts from others, the recipient shall promptly repay such amounts
collected to the indemnifying party, together with any interest earned thereon.

                  (f) In performing the Service-Related Activities contemplated
by this Agreement, the Backup Servicer agrees to comply in all respects with the
applicable state and federal laws and will carry out such activities with the
same degree of care as that provided for the Servicer under the Loan Agreement.
The Backup Servicer shall maintain all state and federal licenses and franchises
necessary for it to perform Service-Related Activities. The Backup Servicer
shall not have any Liability for any Error or Continued Error by the Servicer,
or for any error, inaccuracy or omission of the Servicer before the Backup
Servicer assumes the Service-Related Activities.

                  (g) Neither the Backup Servicer nor any of the directors or
officers or employees or agents of the Backup Servicer shall be under any
liability to the Servicer or any




                                       11

<PAGE>




party to this Agreement or the Loan Agreement except as provided in this
Agreement, for any action taken or for refraining from the taking of any action
in good faith pursuant to this Agreement; provided, however, that this provision
shall not protect the Backup Servicer or any such person against any liability
that would otherwise be imposed by reason of a breach of this Agreement or
willful misfeasance, bad faith or gross negligence (excluding errors in
judgment) in the performance of duties, by reason of reckless disregard of
obligations and duties under this Agreement or any violation of law by the
Backup Servicer or such person, as the case may be. The Backup Servicer and any
director, officer, employee or agent of the Backup Servicer may conclusively
rely and shall be fully protected in acting or refraining from acting upon any
document, certificate, instrument, opinion, notice, statement, consent,
resolution, entitlement order, approval or conversation believed by it to be
genuine and made by the proper person and upon the advice or opinion of counsel
or other experts selected by it. The Backup Servicer shall not be liable for an
error of judgment made in good faith by a Responsible Officer of the Backup
Servicer, unless it shall be proven that the Backup Servicer was negligent in
ascertaining the pertinent facts.

                  (h) The Backup Servicer shall maintain its existence and
rights as a corporation under the laws of the jurisdiction of its incorporation,
and will obtain and preserve its qualification to do business as a foreign
corporation in each jurisdiction in which the failure to so qualify would have
an adverse effect on the validity or enforceability of any Contract, Dealer
Agreement, this Agreement or on the ability of the Backup Servicer to perform
its duties under this Agreement.

                  (i) The provisions of this Section shall survive the
termination of this Agreement.

                  (j) The Backup Servicer shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, entitlement
order, approval or other paper or document.

                  (k) The Backup Servicer may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or
through agents, attorneys, custodians or nominees appointed with due care.

                  (l) To the extent that the Backup Servicer is not indemnified
by the Servicer pursuant to Section 2.2 hereunder and under the Loan Agreement,
such amounts shall be reimbursable by the Borrower pursuant to Section 2.7(a) of
the Loan Agreement.

         SECTION 2.10. Backup Servicer's Certificate. Prior to the Assumption
Date, on or before 12:00 noon (New York City time) on the Business Day preceding
each Payment Date, the Backup Servicer shall deliver or cause to be delivered to
the Deal Agent a certificate (the "Backup Servicer's Certificate"), in form and
substance satisfactory to the Deal Agent, signed by an officer of the Backup
Servicer, stating that (i) the Backup Servicer has loaded the Servicer's Data
File as described in Section 2.1(a) on its hardware, (ii) a review of the
Monthly Report for the related Payment Date has been made under such officer's
supervision, (iii) the Backup Servicer has received the Live Data File described

verification set forth in Section 2.2(a) and 2.2(b), the data on the Servicer's
Data File tie to the related Monthly Report resulting in no discrepancies
between them, and (z) the Monthly Report does not contain any errors in
accordance with the review criteria set forth in Section 2.2(a) hereunder. If
the preceding statements cannot be made in the affirmative, the applicable
officer shall state the nature of any and all anomalies, discrepancies and
errors, and indicate all actions it is currently taking with the Servicer to
reconcile and/or correct the same. Each Backup Servicer's Certificate shall be
dated as of the related Determination Date. Upon the request of the Deal Agent,
a Backup Servicer's Certificate shall be accompanied by copies of any third
party reports relied on or obtained in connection with the Backup Servicer's
duties hereunder. The Backup Servicer, with respect to the Backup Servicer's
Certificate, shall not be responsible for delays attributable to the Servicer's
or Borrower's failure to deliver information, defects in the information
supplied by the Servicer or other circumstances beyond the control of the Backup
Servicer. After the Assumption Date, the Backup Servicer shall deliver the
Monthly Report in accordance with Section 6.5(a) of the Loan Agreement.

         SECTION 2.11. Backup Servicer's Expenses. The Backup Servicer shall be
required to pay all expenses incurred by it in connection with its activities
hereunder, including fees and disbursements of independent accountants, taxes
imposed on the Backup Servicer and expenses incurred in connection with
distributions and reports to the Servicer, the Collateral Agent and the Deal
Agent. When the Backup Servicer incurs expenses after the occurrence of a
Servicer Termination Event specified in Section 6.11 of the Loan Agreement, the
parties hereto intend that such expenses constitute expenses of administration
under the Bankruptcy Code or any other applicable Federal or State bankruptcy,
insolvency or similar law.
