provided,  however,  that by  acceptance  of this Policy the  Indenture  Trustee
agrees to provide upon request to Financial Security a notice and certificate in
respect of any such payment by Financial  Security.  Financial Security shall be
entitled to pay hereunder any amount due on the  Obligations  on an  accelerated
basis at any  time or from  time to  time,  in  whole  or in part,  prior to the
scheduled date of payment thereof;  Scheduled  Payments insured  hereunder shall
not include  interest,  in respect of principal paid hereunder on an accelerated
basis,  accruing  from after the date of such  payment of  principal.  Financial

herein whether or not such funds are properly applied by the Indenture Trustee.

         3. Notices and  Conditions to Payment in Respect of Scheduled  Payments
Avoided  as  Preference  Payments.  If any  Scheduled  Payment  is  avoided as a

because such payments were  avoidable as preference  payments  under  applicable
bankruptcy law (the "Order"), (B) a certificate of the Holder that the Order has
been entered and is not subject to any stay and (C) an assignment  duly executed
and delivered by the Holder, in such form as is reasonably required by Financial
Security,  and  provided  to  the  Holder  by  Financial  Security,  irrevocably
assigning to Financial  Security all rights and claims of the Holder relating to
or arising under the Obligations  against the estate of the Obligor or otherwise
with respect to such preference payment or (ii) the date of Receipt by Financial
Security from the Indenture Trustee of the items referred to in clauses (A), (B)
and (C) above if, at least four  Business  Days  prior to such date of  Receipt,
Financial Security shall have Received written notice from the Indenture Trustee
that such items were to be delivered on such date and such date was specified in
such notice.  Such payment  shall be  disbursed  to the  receiver,  conservator,
debtor-in-possession  or trustee in bankruptcy named in the Order and not to the
Indenture  Trustee or any Holder  directly  (unless a Holder has previously paid
such amount to the  receiver,  conservator,  debtor-in-possession  or trustee in
bankruptcy  named in the Order, in which case such payment shall be disbursed to
the Indenture Trustee for distribution to such Holder upon proof of such payment
reasonably   satisfactory  to  Financial  Security).   In  connection  with  the
foregoing, Financial Security shall have the rights provided pursuant to Section
6.2 of the Sale and Servicing Agreement.

         4.  Governing  Law.  This Policy shall be governed by and  construed in
accordance  with the laws of the State of New York without  giving effect to the
conflict of laws principles thereof.

Security may appoint a fiscal  agent (the  "Fiscal  Agent") for purposes of this
Policy  by  written  notice  to the  Indenture  Trustee  at the  notice  address
specified in the Indenture  specifying the name and notice address of the Fiscal
Agent.  From and  after the date of  receipt  of such  notice  by the  Indenture
Trustee,  (i) copies of all notices and  documents  required to be  delivered to
Financial Security pursuant to this Policy shall be simultaneously  delivered to
the Fiscal  Agent and to  Financial  Security  and shall not be deemed  Received
until Received by both,  and (ii) all payments  required to be made by Financial
Security under this policy may be made directly by Financial  Security or by the

Financial  Security only and the Fiscal Agent shall in no event be liable to any
Holder for any acts of the Fiscal Agent or any failure of Financial  Security to
deposit,  or cause to be deposited,  sufficient funds to make payments due under
the Policy.

         6. Waiver of Defenses.  To the fullest  extent  permitted by applicable
law, Financial Security agrees not to assert, and hereby waives, for the benefit
of each Holder,  all rights (whether by  counterclaim,  setoff or otherwise) and
defenses  (including,  without  limitation,  the  defenses  of  fraud),  whether
acquired by subrogation, assignment or otherwise, to the extent that such rights

         Re:      CPS Auto Receivables Trust 1998-4

         The undersigned,  a duly authorized  officer of Norwest Bank Minnesota,
National  Association (the "Indenture  Trustee"),  hereby certifies to Financial
Security  Assurance  Inc.  ("Financial  Security"),  with reference to Financial
Guaranty  Insurance  Policy No.  50749-N dated  December 4, 1998 (the  "Policy")

Asset Backed Notes, $77,500,000 Class A-2 5.790% Asset Backed Notes, $81,375,000

Notes  and   $18,625,000   Class  A-5   5.890%   Asset   Backed   Notes  of  the
above-referenced Trust (the "Obligations"), that:

         (i) The Indenture Trustee is the Trustee under the Indenture.

         (ii) The sum of all amounts on deposit (or  scheduled to be on deposit)
in the Note  Distribution  Account and available for distribution to the Holders
pursuant to the Indenture  will be $_________  (the  "Shortfall")  less than the
aggregate amount of Scheduled Payments due on ___________________.

         (iii) The Indenture  Trustee is making a claim under the Policy for the
Shortfall to be applied to the payment of Scheduled Payments.

         (iv) The Indenture Trustee agrees that, following receipt of funds from
Financial  Security,  it shall (a) hold such amounts in trust and apply the same
directly to the payment of Scheduled  Payments on the Obligations  when due; (b)
not apply such funds for any other  purpose;  (c) not commingle  such funds with
other funds held by the Indenture Trustee and (d) maintain an accurate record of
such payments with respect to each Obligation and the corresponding claim on the
Policy  and  proceeds  thereof,  and,  if  the  Obligation  is  required  to  be
surrendered or presented for such payment,  shall stamp on each such  Obligation
the legend  $"[insert  applicable  amount]  paid by  Financial  Security and the
balance  hereof has been  cancelled  and  reissued"  and then shall deliver such
Obligation to Financial Security.

         (v) The Indenture Trustee, on behalf of the Holders,  hereby assigns to
Financial  Security the rights of the Holders with respect to the Obligations to
the extent of any payments under the Policy, including,  without limitation, any

the offer and sale of the Obligations.  The foregoing  assignment is in addition
to, and not in  limitation  of,  rights of  subrogation  otherwise  available to
Financial  Security in respect of such payments.  Payments to Financial Security
in  respect  of the  foregoing  assignment  shall in all cases be subject to and
subordinate  to the rights of the Holders to receive all  Scheduled  Payments in
respect of the  Obligations.  The  Indenture  Trustee shall take such action and
deliver such instruments as may be reasonably requested or required by Financial
Security to effectuate the purpose or provisions of this clause (v).

         (vi) The Indenture  Trustee on its behalf and on behalf of the Holders,
hereby  appoints  Financial  Security  as  agent  and  attorney-in-fact  for the
Indenture  Trustee and each such Holder in any legal  proceeding with respect to
the Obligations. The Indenture Trustee hereby agrees that, so long as an Insurer
Default (as defined in the Indenture) shall not exist, Financial Security may at
any time during the  continuation  of any  proceeding  by or against the Obligor
under the United  States  Bankruptcy  Code or any other  applicable  bankruptcy,
insolvency,   receivership,   rehabilitation  or  similar  law  (an  "Insolvency
Proceeding")  direct  all  matters  relating  to  such  Insolvency   Proceeding,
including  without  limitation,  (A)  all  matters  relating  to  any  claim  in
connection with an Insolvency Proceeding seeking the avoidance as a preferential
transfer of any payment  made with  respect to the  Obligations  (a  "Preference
Claim"), (B) the direction of any appeal of any order relating to any Preference
Claim at the  expense of  Financial  Security  but subject to  reimbursement  as
provided  in the  Insurance  Agreement  and  (C)  the  posting  of  any  surety,
supersedeas  or  performance  bond  pending any such appeal.  In  addition,  the
Indenture Trustee hereby agrees that Financial  Security shall be subrogated to,
and the  Indenture  Trustee on its behalf and on behalf of each  Holder,  hereby
delegates and assigns, to the fullest extent permitted by law, the rights of the
Indenture  Trustee and each Holder in the conduct of any Insolvency  Proceeding,
including,  without  limitation,  all  rights  of  any  party  to  an  adversary
proceeding or action with respect to any court order issued in  connection  with
any such Insolvency Proceeding.

         (vii)  Payment  should be made by wire  transfer  directed  to [SPECIFY
