by  appropriate tax  authorities, the Trust  will file  or cause to  be filed
annual or  other necessary returns,  reports and other forms  consistent with
the characterization of the Trust as a security arrangement for the  issuance
of debt for  such tax purposes.   Effective as of the date  hereof, the Owner
Trustee shall have all rights, powers and duties  set forth herein and in the
Business  Trust Statute  with respect  to accomplishing  the purposes  of the
Trust.  The Owner Trustee  is hereby authorized to file with the Secretary of
State of the State of Delaware a Certificate of Trust of the Trust.

     Section 2.07.  Limitation of Liability.  The Certificateholders shall
                    -----------------------

Corporation Law of the State of Delaware.

     Section 2.08.  Title to Trust Property.  Legal title to the Trust Estate
                    -----------------------

where applicable law  in any jurisdiction requires  title to any part  of the
Trust Estate to be vested in a trustee or trustees, in which case title shall
be deemed  to be vested in the Owner  Trustee, a co-trustee and/or a separate
trustee, as the case may be.

     Section 2.09.  Situs of Trust.  The Trust will be located and
                    --------------
administered in  the State of Delaware.  All  bank accounts maintained by the
Owner Trustee  on  behalf of  the Trust  shall  be located  in  the State  of
Delaware or the State of New York.  The Trust shall not have any employees in
any state other  than Delaware; provided, however, that  nothing herein shall
restrict  or prohibit  the  Owner  Trustee from  having  employees within  or
without the State of Delaware.   Payments will be received by the Trust  only
in Delaware or  New York, and payments  will be made  by the Trust only  from
Delaware or New York.  The only office of the Trust will  be at the Corporate

     or insolvency law; in each such case  without the unanimous consent of 
     its Board of Directors.

     Section 2.11.  Representations and Warranties of the Depositor with
                    ----------------------------------------------------
Respect to the CABS.  The Depositor makes the following representations and
- -------------------
warranties as to the CABS to the Owner Trustee, the Swap Counterparty and the
Swap Guarantor on which the Trust relies in accepting the CABS and delivering
the  Securities.    Such  representations  and warranties  speak  as  of  the
execution and delivery  of this  Agreement and  as of the  Closing Date,  but
shall survive the  sale, transfer and assignment of the CABS by the Depositor
to the Trust and  the pledge thereof to the Indenture Trustee pursuant to the
Indenture.

     (a)  Title.  It is the intention of the Depositor that (i) the transfer
          -----
and assignment  herein contemplated constitute  a sale of  the CABS from  the
Depositor to  the Trust, conveying good title thereto,  free and clear of any
Liens or rights  of other  Persons and  (ii) the beneficial  interest in  and
title to  the CABS not  be part of  the debtor's estate  in the event  of the
filing  of a  bankruptcy  petition by  or  against  the Depositor  under  any
bankruptcy law.   None of the CABS  have been sold, transferred,  assigned or
pledged by  the Depositor to  any Person other  than the Trust.   Immediately
prior to the  transfer and assignment herein contemplated,  the Depositor had
good and marketable title to each of the CABS free and clear of all Liens and
rights of others and, immediately upon the transfer  thereof, the Trust shall
have good and marketable title to each such CABS, free and clear of all Liens
and rights of others; and the transfer has been perfected under the UCC.

     (b)  All Filings Made.  All filings (including UCC filings) necessary
          ----------------
in any jurisdiction to give the Trust a first perfected ownership interest in
the CABS have been made.


                                 ARTICLE III

                           Conveyance of the CABS;
                          -----------------------
                  Certificates; Appointment of Administrator
                  ------------------------------------------

     Section 3.01.  Conveyance of the CABS.  The Depositor, upon the
                    ----------------------
execution and delivery hereof, does  hereby transfer, convey, sell and assign
to the Trust, on behalf of the Holders of the Certificates, without recourse,
all  the right,  title  and interest  of the  Depositor  in and  to  the CABS
including all  distributions thereon, payable  on and after the  Closing Date
and all other assets included or to  be included in the Trust for the benefit
of Certificateholders.  

     The parties  hereto intend that  the transaction  set forth herein  be a
sale by the Depositor to the Trust of all of the Depositor's right, title and
interest in  and to the CABS and the other  property described above.  In the
event that the transaction set forth  herein is not deemed to be a  sale, the
Depositor hereby  grants  to the  Trust a  security interest  in  all of  the
Depositor's right,  title  and  interest  in,  to and  under  the  CABS,  all
distributions  thereon  and all  proceeds thereof;  and this  Trust Agreement
shall constitute a security agreement under applicable law.

     In  connection  with such  transfer  and assignment,  the  Depositor has
provided a  fully executed  copy of this  Trust Agreement, including  a fully
completed copy of Exhibit B hereto, to the Indenture Trustee as  a "financial
intermediary"  (as defined in the UCC as  in effect in the State of Delaware)
and has caused the beneficial ownership interest in the CABS to be registered
with the Depository (on whose books the interest of the Depositor in the CABS
appears) in the name of the "financial intermediary" as defined in Section 8-
313(4) of the UCC for the account of the Trust.

     Section 3.02.  Initial Ownership.  Upon the formation of the Trust by
                    -----------------
the  contribution by  the Depositor  pursuant to  Section 2.05 and  until the
transfer of the Certificates to the purchaser thereof, the Depositor shall be
the sole beneficiary of the Trust.

     Section 3.03.  The Certificates.  (a) The Certificates shall be issued
                    ----------------
substantially in the form set forth in Exhibit A in minimum  denominations of
$100,000 and in integral multiples of $1,000 in excess thereof; or any amount
as  specified above  plus  such lesser  amount.   The  Certificates shall  be
executed  on behalf  of the  Trust  by manual  or facsimile  signature  of an
authorized officer of the Owner Trustee.  Certificates bearing the  manual or
facsimile  signatures  of  individuals  who  were,  at  the  time  when  such
signatures shall  have been  affixed, authorized  to sign  on  behalf of  the
Trust, shall be  validly issued  and entitled  to the benefit  of this  Trust
Agreement, notwithstanding  that such individuals  or any of them  shall have
ceased to  be so authorized prior to the  authentication and delivery of such
Certificates or did not  hold such offices at the date  of authentication and
delivery of such Certificates.  A Person shall become a Certificateholder and
shall  be  entitled to  the  rights  and  subject  to the  obligations  of  a
Certificateholder  hereunder upon such  Person's acceptance of  a Certificate
duly registered in such Person's name, pursuant to Section 3.09.

     (b) A transferee  of a Certificate shall become  a Certificateholder and
shall be  entitled  to  the  rights  and subject  to  the  obligations  of  a
Certificateholder   hereunder  upon   such  transferee's   acceptance  of   a
Certificate duly registered  in such  transferee's name  pursuant to  Section
3.09.

     (c) The Certificates  shall accrue interest  at the Certificate  Accrual
Rate.  Such amounts shall be due  and payable on each Payment Date.  Interest
shall accrue with  respect to each Payment  Date during the one  month period
beginning at  the close of business on the preceding  Payment Date (or on the
Closing  Date in the case of the first  Payment Date) and ending at the close
of  business  on such  Payment  Date  (each  an "Interest  Accrual  Period").
Interest  on the  Certificates shall  be payable  solely from amounts  in the
Collection Account, including amounts received pursuant to the Swap Agreement
and Swap  Policy  with respect  to  interest, and  shall  be subject  to  the
Priority  of Payments.  Beginning on  the Principal Commencement Date, and on
each  Payment  Date thereafter,  principal  payable  on the  Certificates  as
described in Section  3.03(d) on any Payment  Date will be calculated  by the
Calculation Agent, and  will be paid to the  Certificateholders in accordance
with  the Percentage  Interest represented  by  each such  Certificate.   Any
installment of interest or principal, if any, payable on any Certificate that
is punctually  paid or  duly provided  for by  the Issuer  on the  applicable
Payment Date  shall  be  paid to  each  Certificateholder of  record  on  the
preceding Record Date, by wire transfer to an account specified in writing by
such Certificateholder reasonably  satisfactory to the  Owner Trustee or  the
Administrator  as  of  the  preceding  Record  Date   or  by  check  to  such
Certificateholder  mailed to  such  Holder's  address as  it  appears in  the
Certificate Register if no such instructions have been delivered to the Owner
Trustee or the Administrator.

     (d)  Principal due  on the  Certificates  shall be  payable solely  from
amounts in  the  Collection  Account,  including amounts,  if  any,  received
pursuant to the Swap Agreement and Swap  Policy, and shall be subject to  the
Priority  of Payments.  Beginning  on the Principal  Commencement Date and on
each Payment  Date thereafter, principal  payable on the Certificates  on any
Payment  Date will  be  equal  to the  Certificate  Amortization Amount  with
respect to such Payment Date, as determined by the Calculation Agent. 

     The Calculation Agent shall calculate the PSA Index Rate and the Monthly
Amortization Rate  on the  Prepayment Determination Date  as provided  in the
Indenture and shall  promptly notify  the Administrator of  the same time  it
notifies the Indenture Trustee pursuant to the Indenture.

     If the aggregate  outstanding principal amount of the  Notes immediately
after any Payment  Date would be less  than or equal to 10%  of the aggregate
original principal  amount of the  Notes, the  Issuer will prepay  the entire
Face Amount  of the Certificates on such Payment  Date.  The prepayment price
for any  such payment of  principal on the Certificates  will be 100%  of the
Face Amount of such Certificates.

     The  Issuer  has no  optional  prepayment  rights  with respect  to  the
Certificates.

     As provided  in  the  Indenture, in  connection  with  each  prepayment,
repayment or  other payment of  principal in respect  of the Certificates  as
required  by this  Section 3.03,  the  Indenture Trustee  shall instruct  the
Market Agent to sell CABS and/or  Eligible Investments in accordance with the
Sale Procedures.

     In the event of a  CABS Early Amortization Event to the extent  that the
Trust receives proceeds from any CABS in an amount that is less than the face
amount of such CABS (a "Credit Loss"), the Face Amount of the Certificates
                        -----------
will  be reduced by  the amount of  such Credit Loss  until it  is reduced to
zero.  Any such principal reduction will not be reinstated.  It is understood
and acknowledged that such  reduction of the Face Amount  of the Certificates
shall  be  effective to  reduce  the  outstanding  principal amount  of  each
Certificate,  and  that all  references  to  Face Amount,  principal  amount,
outstanding principal  amount and  other references to  the principal  due in
respect of a Certificates shall take into effect to such reduction.

     Notwithstanding the foregoing, the entire unpaid principal amount of the
Certificates shall be due and payable, if not previously paid, on the date on
which any  Event of Default (other than the  events described in clause (iv),
(v) or (vi) of the definition of Event of Default) shall have occurred and be
continuing, if the  Indenture Trustee shall  at the direction  of Holders  of
Notes representing not less than a majority of the Principal Amount  of Notes
(or,  in the case  of an Event  of Default described  in clause  (iii) in the
definition thereof,  all  Securityholders)  have  declared the  Notes  to  be
immediately  due  and payable  pursuant  to  the  Indenture.   All  principal
payments on  Certificates shall  be made  to the Certificateholders  entitled
thereto  in accordance  with  the Percentage  Interests  represented by  such
Certificates, subject to the Priority of Payments.  The Certificate Registrar
shall send a notice to  each Person in whose name a Certificate is registered
at the close  of business on the Record Date preceding the final distribution
date or other earlier  date of prepayment  of the entire  Face Amount of  the
Certificates.  Such notice  shall be mailed no later than  five Business Days
prior to such date and shall specify that payment of the principal amount and
any interest  due with  respect to  such Certificate  at such  date shall  be
payable only upon presentation and surrender of such Certificate to the Owner
Trustee and shall specify  the place where such Certificate may  be presented
and surrendered  for such final  payment.  By acceptance  of any Certificate,
the Holder thereof agrees to surrender such Certificate to the Owner  Trustee
promptly, prior  to such  Certificateholder's receipt  of  the final  payment
thereon.

     Upon  a rescission  pursuant  to  Section 3.05  of  the Indenture,  such
rescission  shall  also be  effective  hereunder  to  rescind and  annul  the
declaration of an  Event of Default and  the acceleration of maturity  of the
Certificates.   No  such rescission  shall affect  any subsequent  default or
impair any rights consequent thereto.

     The entire  unpaid principal  amount of  the  Certificates shall  become
immediately due and payable automatically upon the occurrence of an Event  of
Default specified  in clause  (iv), (v)  or (vi) of  the definition  thereof.
Immediately  after the occurrence of an Event  of Default described in clause
(iv), (v) or  (vi) of the  definition of  Event of Default,  pursuant to  the
terms  of the Indenture,  the Indenture Trustee shall  sell and liquidate (or
shall cause  to be sold and liquidated) the  CABS and Eligible Investments in
accordance with the Sale Procedures.

     (e) Any  amounts in respect of the Certificates  not paid when due under
this Trust Agreement (including any overdue interest) shall accrue  interest,
to the extent permitted  by applicable law,  at the Certificate Accrual  Rate
until paid as provided in this Trust Agreement.

     Section 3.04.  The Global Certificates.  The aggregate Denominations of
                    -----------------------
all  Certificates  issued  as  of  the  Closing  Date  shall  be  $7,735,000.
Beneficial Owners will hold interests  in the Global Certificates through the
book-entry facilities of the Depository in minimum  Denominations of $100,000
and integral multiples of $1,000 in excess thereof.

     The Certificates shall  be issued initially in  the form of one  or more
permanent  Global Certificates in  definitive, fully registered  form without
interest coupons  with the applicable legend  set forth in  Exhibit A hereto,
respectively,  added  to the  form  of  such  Certificates (each,  a  "Global
Certificate"), which shall be deposited on behalf of the subscribers for such
Certificates represented thereby with the  Owner Trustee as custodian for the
Depository and registered  in the name of  a nominee of the  Depository, duly
executed by  the Owner  Trustee and  authenticated  by the  Owner Trustee  as
hereinafter  provided.     The  aggregate  principal  amount  of  the  Global
Certificates may from  time to time be  decreased by adjustments made  on the
records of the Owner  Trustee or the Depository  or its nominee, as  the case
may be, as hereinafter provided.

     The Owner Trustee may for all purposes (including the making of payments
due on the Global  Certificates) deal with the  Depository as the  authorized
representative  of  the  Beneficial  Owners   with  respect  to  the   Global
Certificates for the purposes of exercising the rights of  Certificateholders
hereunder.   Except as  provided  in the  next succeeding  paragraph of  this
Section  3.04, the  rights of  Beneficial Owners with  respect to  the Global
Certificates  shall be  limited to  those established  by law  and agreements
between   such  Beneficial   Owners  and   the   Depository  and   Depository
Participants.   Except as provided  in Section 3.07, Beneficial  Owners shall
not be entitled to  definitive notes for the Global Certificates  as to which
they are the  Beneficial Owners.  Requests and directions from, and votes of,
the Depository as Certificateholder shall  not be deemed inconsistent if they
are made with respect to different Beneficial  Owners.  The Owner Trustee may
establish  a  reasonable  record date  in  connection  with  solicitations of
consents  from  or  voting  by  Certificateholders and  give  notice  to  the
Depository of such  record date.  Without  the consent of the  Issuer and the
Owner Trustee,  no Global  Certificate may be  transferred by  the Depository
except to a  successor Depository that agrees to hold such Global Certificate
for the account of the Beneficial Owners.

     In  the event  The  Depository Trust  Company resigns  or is  removed as
Depository,  the  Depositor  may  appoint  a successor  Depository.    If  no
successor Depository  has been appointed within 30 days of the effective date
of the  Depository's resignation or  removal, each Beneficial Owner  shall be
entitled  to certificates representing the Global Certificate it beneficially
owns in the manner prescribed in Section 3.07.

     Section 3.05.  Book-Entry Certificates.  This section shall apply only
                    -----------------------
to Global Certificates deposited with or on behalf of the Depository.

     The Owner Trustee  shall execute, on behalf of the Issuer, and the Owner
Trustee  shall  authenticate  and  deliver   initially  one  or  more  Global
Certificates that (i) shall  be registered in the name of  the nominee of the
Depository for such Global  Certificates and (ii) shall  be delivered by  the
Owner   Trustee  to  such   Depository  or  pursuant   to  such  Depository's
instructions or  held  by the  Owner  Trustee's agent  as custodian  for  the
Depository.   Such Global Certificates  shall initially be registered  on the
Certificate Register in the  name of Cede & Co.,  the nominee of the  initial
Depository, and  no Beneficial  Owner will  receive a Definitive  Certificate
representing such Beneficial Owner's interest  in such Certificate, except as
provided in  Section 3.07.   Unless  and until  definitive, fully  registered
Certificates (the "Definitive  Certificates") have been issued  to Beneficial
Owners pursuant to Section 3.07:

               (i)  the  provisions  of this  Section 3.05  shall be  in full
     force and effect;

               (ii) the  Certificate Registrar and the Owner Trustee shall be
     entitled  to deal with the Depository for all purposes of this Agreement
     (including the payment of principal  of and interest on the Certificates
     and  the giving  of instructions  or directions  hereunder) as  the sole
     holder of the Global  Certificates, and shall have no obligation  to the
     applicable Certificate Owners;

               (iii) to  the extent that the provisions  of this Section 3.05
     conflict with any other provisions  of this Agreement, the provisions of
     this Section 3.05 shall control;

               (iv) the rights of Beneficial  Owners shall be exercised  only
     through  the Depository and shall be limited to those established by law
     and agreements between such Certificate Owners and the Depository and/or
     the  Depository  Participants  pursuant to  the  Certificate  Depository
     Agreement.  Unless and until Definitive Certificates are issued pursuant
     to Section 3.07, the  initial Depository will make  book-entry transfers
     among the Depository  Participants and receive and transmit  payments of
     principal of and interest on  the Global Certificates to such Depository
     Participants; and

               (v) whenever this Agreement requires or permits actions to  be
     taken  based upon  instructions  or  directions  of  Holders  of  Global
     Certificates evidencing a  specified percentage of the  Principal Amount
     of the  Certificates, the Depository  shall be deemed to  represent such
     percentage only to the extent that  it has received instructions to such
     effect from Beneficial  Owners and/or Depository Participants  owning or
     representing, respectively,  such required percentage  of the beneficial
     interest in the Global Certificates  and has delivered such instructions
     in writing to the Owner Trustee.

     Section 3.06.  Notices to Depository.  Whenever a notice or other
                    ---------------------
communication   to  the  Certificateholders  is  required  under  this  Trust
Agreement, unless and until Definitive Certificates shall have been issued to
Beneficial Owners pursuant to Section 3.07,  the Owner Trustee shall give all
such notices  and communications specified herein  to be given to  Holders of
the Global Certificates  to the Depository, and  shall have no obligation  to
the Beneficial Owners.

     Section 3.07.  Definitive Certificates.  If (i) the Administrator
                    -----------------------
advises  the Indenture  Trustee and  the Owner  Trustee in  writing that  the
Depository  is  no   longer  willing  or  able  to   properly  discharge  its
responsibilities   with  respect   to  the   Global   Certificates  and   the
Administrator  is  unable   to  locate  a  qualified  successor  or  (ii) the
Administrator at its option advises the  Owner Trustee and the Owner  Trustee
in writing that it elects to  terminate the book-entry system of registration
through the Depository,  then the Depository will  be expected to notify  all
Beneficial  Owners  of   the  availability  of  Definitive   Certificates  to
Beneficial Owners requesting  the same.  Upon surrender  to the Owner Trustee
of the typewritten  Certificates representing the Book-Entry  Certificates by
the  Depository,  accompanied  by  re-registration  instructions,  the  Owner
Trustee, on  behalf of the Issuer, shall execute  and the Owner Trustee shall
authenticate  the Definitive Certificates in accordance with the instructions
of  the Depository.   None of  the Issuer,  the Certificate Registrar  or the
Owner Trustee shall be liable for any delay in delivery of  such instructions
and may conclusively  rely on,  and shall  be protected in  relying on,  such
instructions.    Upon the  issuance  of  Definitive Certificates,  the  Owner
Trustee  shall  recognize  the  Holders  of  the Definitive  Certificates  as
Certificateholders.

     Section 3.08.  Authentication of Certificates.  Concurrently with the
                    ------------------------------
initial  sale of the  CABS to  the Trust, the  Owner Trustee  shall cause the
Certificates  in  an   aggregate  principal  amount  equal  to   the  Initial
Certificate Balance to be executed on behalf of the Trust,  authenticated and
delivered to  or  upon the  written order  of the  Depositor,  signed by  its
chairman of the  board, its president, any  vice president, secretary  or any
assistant treasurer, without  further corporate action  by the Depositor,  in
authorized denominations.   No  Certificate shall entitle  its holder  to any
benefit under  this Trust Agreement or be valid  for any purpose unless there
shall   appear  on   such  Certificate   a   certificate  of   authentication
substantially  in the  form set  forth in  Exhibit A,  executed by  the Owner
Trustee or the Administrator, as  the Trust's authenticating agent, by manual
signature; such authentication shall constitute conclusive evidence that such
Certificate shall have been duly  authenticated and delivered hereunder.  All
Certificates shall be dated the date of their authentication.

     Section 3.09.  Registration of Transfer and Exchange of Certificates. 
                    -----------------------------------------------------
The Certificate Registrar shall  keep or cause to  be kept, at the  office or
agency  maintained  pursuant  to Section 3.13,  a  certificate  register (the
"Certificate Register") in  which, subject to such reasonable  regulations as
it  may  prescribe,   the  Trust  shall  provide  for   the  registration  of
Certificates  and  of  transfers  and exchanges  of  Certificates  as  herein
provided.  The Administrator shall be the initial Certificate Registrar.

     Upon surrender  for registration of  transfer of any Certificate  at the
office  or  agency  maintained  pursuant to  Section 3.13,  the  Trust  shall
execute, authenticate and deliver in the name of the designated transferee or
transferees, one  or more new  Certificates in authorized denominations  of a
like aggregate amount dated  the date of authentication by the  Owner Trustee
or any authenticating  agent.  At the option of a Holder, Certificates may be
exchanged  for  other Certificates  of  authorized  denominations of  a  like
aggregate amount  upon surrender of the  Certificates to be  exchanged at the
office or agency maintained pursuant to Section 3.13.

     Every  Certificate presented or surrendered for registration of transfer
or exchange shall be accompanied by a  written instrument of transfer in form
satisfactory to the Certificate Registrar duly executed by the Holder or such
Holder's attorney duly  authorized in writing.  Each  Certificate surrendered
for registration of transfer or  exchange shall be cancelled and subsequently
disposed of  by the  Certificate Registrar in  accordance with  its customary
practice.

     No service  charge shall  be made  for any registration  of transfer  or
exchange of Certificates, but the  Owner Trustee or the Certificate Registrar
may require payment  of a  sum sufficient  to cover any  tax or  governmental
charge that  may be imposed  in connection with  any transfer or  exchange of
Certificates.

     The  preceding provisions  of this  Section  notwithstanding, the  Owner
Trustee shall  not make,  and the Certificate  Registrar shall  not register,
transfers or exchanges of, Certificates for a period of 15 days preceding the
due date for any payment with respect to the Certificates.

          Each purchaser  of the Certificates  or a beneficial interest  in a
Global  Certificate will be deemed to have  represented and agreed as follows
(terms used  in  this paragraph  that  are defined  in  Rule 144A  under  the
Securities Act are used herein as defined therein):

          (a)  The  purchaser  either  (A)(1)  is  a qualified  institutional
     buyer, (2) is  aware that the sale  of the Certificates  to it is  being
     made in  reliance on  the exemption from  registration provided  by Rule
     144A under the Securities Act and (3)  is acquiring the Certificates for
     its  own account  or  for one  or  more  accounts, each  of  which is  a
     qualified institutional  buyer, and  as to each  of which  the purchaser
     exercises  sole investment  discretion, or  (B)(1)  is an  institutional
     accredited  investor described  in Rule  501(a)(1), (2),  (3) or  (7) of
     Regulation  D under  the Securities  Act  (an "Institutional  Accredited
     Investor") and  (2) is acquiring  the Certificates for its  own account.
     The  purchaser  has such  knowledge  and  experience  in  financial  and
     business matters as  to be capable of evaluating the merits and risks of
     its investment in the Certificates,  and the purchaser, and any accounts
     for which  it is acting, are each able to  bear the economic risk of the
     purchaser's or its investment.

          (b)  The  purchaser understands  that  the Certificates  are  being
     offered only in a transaction  not involving any public offering  in the
     United States within the meaning of the Securities Act, the Certificates
     have not been and will not be  registered under the Securities Act, and,
     if in  the  future the  purchaser decides  to offer,  resell, pledge  or
     otherwise transfer the  Certificates, such Certificates may  be offered,
     resold,  pledged or  otherwise transferred only  in accordance  with the
     applicable legend on such  Securities.  The purchaser acknowledges  that
     no representation is  made by the Indenture Trustee,  the Owner Trustee,
     the Administrator, the Swap Counterparty, the  Swap Guarantor, or Lehman
     Brothers  Inc., as  the  case may  be,  as to  the  availability of  any
     exemption  under the  Securities Act  or any  state securities  laws for
     resale of the Certificates.

          (c)  The purchaser is not purchasing  the Certificates with a  view
     to the resale, distribution or other disposition thereof in violation of
     the Securities Act.  The purchaser understands that an investment in the
     Certificates involves certain  risks, including the risk of  loss of all
     or a substantial  part of  its investment  under certain  circumstances.
     The purchaser  has had  access to such  financial and  other information
     concerning  the Trust  and  the  Securities as  it  deemed necessary  or
     appropriate in  order  to  make an  informed  investment  decision  with
     respect to its purchase of the Certificates.

          (d)  In connection with the purchase of the Certificates: (A)  none
     of the Owner Trustee, the Indenture Trustee, the Administrator, the Swap
     Counterparty, the Swap Guarantor, Lehman Brothers Inc., or the Depositor
     is  acting as  a fiduciary or  financial or  investment adviser  for the
     purchaser;  (B) the purchaser is not relying (for purposes of making any
     investment   decision  or  otherwise)   upon  any  advice,   counsel  or
     representations  (whether written  or oral)  of the  Owner  Trustee, the
     Indenture  Trustee, the Administrator,  the Swap Counterparty,  the Swap
     Guarantor, or the Depositor other  than in a current offering memorandum
     for such Certificates  and any representations expressly set  forth in a
     written agreement  with such party; (C)  none of the  Owner Trustee, the
     Indenture  Trustee, the Administrator,  the Swap Counterparty,  the Swap
     Guarantor,  Lehman Brothers  Inc. or  the  Depositor have  given to  the
     purchaser   (directly  or  indirectly  through  any  other  person)  any
     assurance, guarantee, or representation whatsoever as to the expected or
     projected success, profitability,  return, performance, result,  effect,
     consequence,  or benefit (including  legal, regulatory,  tax, financial,
     accounting,  or otherwise) of  the Trust  Agreement, the  Indenture, the
     Swap  Agreement or  documentation  for  the  Certificates; and  (D)  the
     purchaser has consulted with  its own legal, regulatory, tax,  business,
     investment,  financial, and  accounting advisers  to the  extent it  has
     deemed  necessary,  and  it  has  made   its  own  investment  decisions
     (including  decisions  regarding  the  suitability  of  any  transaction
     pursuant to the Trust Agreement, the Swap Agreement and Indenture) based
     upon its own judgment and  upon any advice from such advisers  as it has
     deemed necessary  and not upon any view  expressed by the Owner Trustee,
     the  Administrator, the  Swap  Counterparty,  the  Swap  Guarantor,  the
     Indenture Trustee, Lehman Brothers Inc. or the Depositor.

          (e)  The  purchaser understands that the Certificates will bear the
     applicable legend set forth in Exhibit A hereto.

          (f)  The purchaser will not, at any time, offer to buy or  offer to
     sell  the  Certificates   by  any  form   of  general  solicitation   or
     advertising,  including, but not limited to, any advertisement, article,
     notice  or other communication  published in any  newspaper, magazine or
     similar  medium or  broadcast over  television  or radio  or seminar  or
     meeting whose  attendees have  been invited  by general  solicitation or
     advertising.

          (g)  The  purchaser  is  not (A)  an  "employee  benefit  plan" (as
     defined  in Section  3(3)  of ERISA)  that is  subject to  the fiduciary
     responsibility  provisions of  ERISA, (B)  a "plan"  that is  subject to
     Section  4975 of  the Code,  (C) a  "governmental  plan" (as  defined in
     Section 3(32)  of ERISA) that is subject to  any federal, State or local
     law which is  substantially similar to the provisions of  Section 406 of
     ERISA or Section  4975 of the Code (the persons or entities described in
     clauses (A),  (B), and (C) being referred  to herein as "Benefit Plans")
     or (D) any person or entity that is using, for purposes of the fiduciary
     responsibility  provisions of  ERISA or  Section 4975  of the  Code, the
     assets of  any Benefit  Plan to  purchase or  hold its  interest in  any
     Securities  (the  person  and entities  described  in  this clause  (D),
     together  with  Benefit  Plans,  being  referred  to  as  "Benefit  Plan
     Investors").

          (g)  The  purchaser is a United States person within the meaning of
     Section 7701(a)(30)  of the Internal  Revenue Code of 1986,  as amended.
     The purchaser understands and agrees  that any purported transfer of the
     Certificates to  a Holder that does not  comply with the requirements of
     this clause (g) shall be null and void ab initio.

     Section 3.10.  Mutilated, Destroyed, Lost or Stolen Certificates.  If
                    -------------------------------------------------
(a) any  mutilated  Certificate  shall  be  surrendered  to  the  Certificate
Registrar,  or if  the Certificate  Registrar shall  receive evidence  to its
satisfaction  of  the destruction,  loss  or  theft  of any  Certificate  and
(b) there  shall be  delivered to  the  Certificate Registrar  and the  Owner
Trustee such security or indemnity as may be required by them to save each of
them harmless,  then in the absence of notice  that such Certificate has been
acquired by a bona  fide purchaser, the Owner Trustee on  behalf of the Trust
shall  execute and  the  Owner Trustee  or  the Administrator,  as  the Owner
Trustee's authenticating agent,  shall authenticate and deliver,  in exchange
for or in lieu of any such  mutilated, destroyed, lost or stolen Certificate,
a new  Certificate of like  tenor and denomination.   In connection  with the
issuance of any new Certificate under this Section 3.09, the Owner Trustee or
the Certificate  Registrar may  require the payment  of a  sum sufficient  to
cover any tax  or other governmental charge that may be imposed in connection
therewith.   Any duplicate Certificate  issued pursuant to this  Section 3.09
shall  constitute  conclusive evidence  of  ownership  in  the Trust,  as  if
originally issued, whether  or not the lost, stolen  or destroyed Certificate
shall be found at any time.

     Section 3.11.  Persons Deemed Certificateholders.  Prior to due
                    ---------------------------------
presentation  of  a  Certificate  for  registration  of  transfer,  the Owner
Trustee,  the Certificate  Registrar  or any  Administrator  shall treat  the
Person  in  whose name  any  Certificate  is  registered in  the  Certificate
Register as  the owner  of  such Certificate  for  the purpose  of  receiving
distributions pursuant to Section 5.02 and for all other purposes whatsoever,
and none of the Owner Trustee, the Certificate Registrar or any Administrator
shall be bound by any notice to the contrary.

     Section 3.12.  Access to List of Certificateholders' Names and
                    -----------------------------------------------
Addresses.  The Owner Trustee shall furnish or cause to be furnished to the
- ---------
Depositor, within  15 days after receipt  by the Owner  Trustee of  a written
request therefor from the Depositor, a  list, in such form as the  Depositor,
may reasonably require, of the  names and addresses of the Certificateholders
as of the most recent  Record Date.  If  three or more Certificateholders  or
one or  more Holders  of Certificates  evidencing not  less than  25% of  the
outstanding  principal of  the Certificates  apply  in writing  to the  Owner
Trustee,   and  such  application  states   that  the  applicants  desire  to
communicate with other Certificateholders with  respect to their rights under
this  Trust Agreement  or  under  the Certificates  and  such application  is
accompanied by  a copy of the  communication that such applicants  propose to
transmit, then the Owner  Trustee shall, within five Business Days  after the
receipt  of such  application, afford  such applicants  access during  normal
business hours to the  current list of  Certificateholders.  Each Holder,  by
receiving and holding  a Certificate, shall be  deemed to have agreed  not to
hold any of  the Depositor,  the Certificate Registrar  or the Owner  Trustee
accountable by reason  of the disclosure of its name  and address, regardless
of the source from which such information was derived.

     Section 3.13.  Maintenance of Office or Agency.  The Trust shall
                    -------------------------------
maintain in the  Borough of Manhattan,  The City  of New York,  an office  or
offices  or agency  or agencies  where  Certificates may  be surrendered  for
registration of transfer or exchange and where notices and demands to or upon
the Owner Trustee in respect of the Certificates and the Basic  Documents may
be served.  The Trust initially designates The Bank of  New York, 101 Barclay
Street, New York, New York 10286 as  its office for such purposes.  The Owner
Trustee  shall  give prompt  written  notice  to  the  Depositor and  to  the
Certificateholders of any change in  the location of the Certificate Register
or any such office or agency.

     Section 3.14.  Appointment of Administrator.  The Administrator shall
                    ----------------------------
undertake  the  obligations of  the  Trust,  pursuant  to the  Administration
Agreement  and  shall  make  distributions  to  Certificateholders  from  the
Collection Account pursuant  to Section 5.02 and shall report  the amounts of
such distributions  to the Owner Trustee.   The Administrator  shall have the
revocable power to withdraw funds from the Collection Account for the purpose
of making the distributions referred  to above.  Notwithstanding Section 4.02
hereof, the Owner Trustee may revoke such power  and remove the Administrator
if the Owner Trustee determines in its sole discretion that the Administrator
shall  have failed to perform  its obligations under  this Trust Agreement in
any material  respect.  The Administrator initially shall  be The Bank of New
York and  shall be  designated pursuant to  the Administration  Agreement and
will perform such  duties as are  set forth therein.   Any reference  in this
Trust Agreement to the Administrator shall include any co-paying agent unless
the context requires otherwise.

     Section 3.15.  Reporting.  At any time when the Trust is not subject to
                    ---------
Section 13  or 15(d) of  the Exchange Act  and is  not exempt from  reporting
pursuant to  Rule 12g3-2(b)  under the Exchange  Act, upon  the request  of a
holder or  beneficial owner  of a Certificate,  the Depositor  shall promptly
furnish  or cause  to be furnished  Rule 144A  Information to such  holder or
beneficial  owner  and  to  any  prospective  purchaser of  such  Certificate
designated  by such holder or beneficial owner,  as the case may be, in order
to permit compliance  by such holder or beneficial owner with Rule 144A under
the Securities Act in connection with the resale of such Certificate  by such
holder or beneficial owner.

     Section 5.01.  Collection of Payments on CABS; Collection Account.  (a) 
                    --------------------------------------------------
The Trust shall cause  the Indenture Trustee pursuant to Section  3.01 of the
Indenture, to establish and maintain  with the Indenture Trustee a segregated
trust  account (the  "Collection  Account")  in the  name  of Mortgage  Index
Amortizing Trust 1997-1 in which the Indenture  Trustee shall, subject to the
terms of  this paragraph,  deposit on  the same  day that  it receives,  each

actions  to collect  any distributions due  on the  CABS and any  amounts due

Certificateholders sufficient  funds for the  payment of any  withholding tax
that is  legally owed by the Trust (but  such authorization shall not prevent
the  Trust from  contesting  any  such tax  in  appropriate proceedings,  and
withholding payment of  such tax, if permitted by law, pending the outcome of
such proceedings).  The amount of any withholding tax imposed with respect to
a  Certificateholder   shall  be   treated  as   cash  distributed  to   such
Certificateholder at the time it is withheld by the Trust and remitted to the
appropriate taxing authority.  If there is a possibility that withholding tax
is  payable  with respect  to a  distribution  (such as  a distribution  to a
non-U.S. Certificateholder), the Owner Trustee shall withhold such amounts in
accordance with this paragraph (e).  The Owner Trustee shall first notify the
Depositor with  respect to  any applicable withholding  taxes imposed  on the
Certificates and no earlier than  5 Business Days thereafter, shall withhold,
at  the  applicable   withholding  rate  (or  backup  withholding   rate,  as
applicable), a portion  of interest payments  otherwise distributable to  any
beneficial  holder of a  Certificate that fails to  provide the Owner Trustee
with a  copy of a  properly completed IRS  Form W-8, IRS  Form W-9, IRS  Form
1001, or IRS Form 4224.

shall  be made to  each Certificateholder of  record on the  preceding Record
Date either  by wire transfer, in immediately available funds, to the account
of  such  Holder at  a bank  or  other entity  having  appropriate facilities
therefor,  if such Certificateholder  shall have provided  to the Certificate
Registrar appropriate written instructions at least five Business Days  prior
to such Payment Date or, if not, by check mailed to such Certificateholder at
the address of such Holder appearing in the Certificate Register.

for federal income tax purposes, (d) cause such tax returns and reports to be
signed  in the  manner required  by law,  (e) notify Certificateholders,  the

Certificateholders.  The Owner Trustee may appoint a firm of certified public
accountants  for purposes  of preparing  and filing  tax returns  and reports
required by this Section 5.04.  The fees of such certified public accountants
shall be paid by  the Owner Trustee, subject to the  Owner Trustee's right of
reimbursement therefor pursuant to Section 8.01 hereof.

     Section 5.05.  Signature on Returns.  The Owner Trustee shall sign on
                    --------------------
behalf of  the Trust  the tax  returns of  the Trust,  unless applicable  law
requires  a Certificateholder  to sign  such  documents, in  which case  such
documents shall be signed by the Depositor.

     Section 5.06.  Statements to Certificateholders.  (a)  The Trust shall
                    --------------------------------

          (v)  the aggregate principal balance of any Eligible Investments as
     of such Payment  Date after giving  effect to any  Sale of any  Eligible
     Investments, and  after giving effect  to the distribution  of principal
     made thereon, on or prior to such Payment Date.

     (b)   The Owner Trustee shall  forward by mail to each Certificateholder
with each  statement described in Section 5.06(a) a  copy of the most current
CABS Distribution Date Statement delivered to the Owner Trustee.

     Section 5.07.  Notices to Owner Trustee.  Upon receipt of any notice
                    ------------------------
with  respect to  the CABS, the  Owner Trustee  shall promptly  transmit such
notice to  the Certificateholders.   In  the  event such  notice requests  or
requires  any action  by the  Owner Trustee  and the  Certificateholders, the
Owner Trustee  shall not take  any action  except in accordance  with written
instructions from the Certificateholders pursuant to Section 6.03(c).


                                  ARTICLE VI

                    -------------------------------------

     Section 6.01.  General Authority.  The Owner Trustee is authorized and
                    -----------------
directed to execute and deliver the Basic Documents to  which the Trust is to
be a party and  each certificate or other document attached as  an exhibit to
or contemplated by  the Basic Documents to which  the Trust is to  be a party
and any amendment or other agreement or instrument described herein, in  each
case, in  such form as the Depositor shall approve, as evidenced conclusively
by the Owner Trustee's execution thereof.  In addition to the  foregoing, the
Owner Trustee is authorized, but shall not  be obligated, to take all actions
required of the Trust pursuant to the Basic Documents.  Subject to compliance
with the  Basic Documents, the Owner Trustee  is further authorized from time
to time to take  such action as the Administrator recommends  with respect to
the Basic Documents.

     Section 6.02.  General Duties.  It shall be the duty of the Owner
                    --------------
Trustee to discharge (or cause to be discharged) all of its  responsibilities
pursuant to the terms  of this Trust Agreement and the  other Basic Documents
to which  the Trust is a party and to administer the Trust in the interest of
the  Certificate-  holders, subject to the Basic Documents  and in accordance
with the provisions of this  Trust Agreement.  Notwithstanding the foregoing,
the  Owner  Trustee  shall  be  deemed  to  have  discharged  its duties  and
responsibilities hereunder  and under the  Basic Documents to the  extent the
Administrator has agreed  in the Administration Agreement to  perform any act
or  to discharge any duty of  the Owner Trustee hereunder  or under any other
Basic  Document, and  the Owner  Trustee  shall not  be held  liable  for the
default or  failure of the  Administrator to carry out  its obligations under
the Administration Agreement.

     Section 6.03.  Action upon Instruction.  (a)  Subject to Article IV and
                    -----------------------
in accordance with  the terms of the Basic  Documents, the Certificateholders
may by written instruction direct the Owner  Trustee in the management of the
Trust.  Such direction may be exercised at any time by written instruction of
the Certificateholders pursuant to Article IV.

     (b)  The  Owner  Trustee  shall  not  be required  to  take  any  action
hereunder  or under  any  Basic Document  if  the  Owner Trustee  shall  have
reasonably determined, or shall have been advised by counsel selected in good
faith, that such action  is likely to result in liability on  the part of the
Owner  Trustee or  is contrary  to  the terms  hereof or  of any  other Basic
Document or is otherwise contrary to law.

     (c)  Whenever the Owner Trustee is unable to  decide between alternative
courses of action permitted or required by  the terms of this Trust Agreement
or  under any  other Basic  Document, the  Owner Trustee shall  promptly give
notice (in such form as shall be appropriate under the circumstances)  to the
Certificateholders  (with  a copy  to  the  Swap  Counterparty and  the  Swap
Guarantor)  requesting instruction as to the  course of action to be adopted,
and to the extent the Owner Trustee acts in good faith in accordance with any
written instruction  of the  Certificateholders received,  the Owner  Trustee
shall not  be liable on account of  such action to any Person.   If the Owner
Trustee  shall not have  received appropriate  instruction within  10 days of
such notice  (or within  such shorter  period of  time as  reasonably may  be
specified in such notice or may be necessary under the circumstances) it may,
but shall be under  no duty to, take  or refrain from taking such  action not
inconsistent with this  Trust Agreement or the  other Basic Documents,  as it
shall deem to be in the  best interests of the Certificateholders, and  shall
have no liability to any Person for such action or inaction.

     (d)  In the event that the Owner Trustee is unsure as to the application
of any provision  of this Trust Agreement or any other  Basic Document or any
such provision  is ambiguous as to its application,  or is, or appears to be,
in conflict with  any other applicable provision,  or in the event  that this
Trust Agreement permits any determination  by the Owner Trustee or is  silent
or  is incomplete  as to  the  course of  action  that the  Owner Trustee  is
required to take with respect to a particular set of facts, the Owner Trustee
may  give  notice   (in  such  form  as   shall  be  appropriate   under  the
circumstances)  to  the   Certificateholders  (with  a   copy  to  the   Swap
Counterparty  and the  Swap  Guarantor) requesting  instruction  and, to  the
extent that the Owner  Trustee acts or refrains from acting  in good faith in
accordance with any such instruction received, the Owner Trustee shall not be
liable, on account of  such action or inaction, to any Person.   If the Owner
Trustee shall  not have  received appropriate  instruction within  10 days of
such notice  (or within  such shorter  period of  time as  reasonably may  be
specified in such notice or may be necessary under the circumstances) it may,
but shall be under  no duty to, take  or refrain from taking such  action not
inconsistent  with this Trust Agreement  or the other  Basic Documents, as it
shall deem to be in the  best interests of the Certificateholders, and  shall
have no liability to any Person for such action or inaction.

     Section 6.04.  No Duties Except as Specified in this Trust Agreement or
                    --------------------------------------------------------
in Instructions.  The Owner Trustee shall not have any duty or obligation to
- ---------------
manage, make any payment with respect to, register, record, sell, dispose of,
or otherwise deal with the Trust Estate, or to otherwise take or refrain from
taking any  action under,  or in connection  with, any  document contemplated
hereby to which the Owner Trustee is a party, except as expressly provided by
the terms of this  Trust Agreement or in any document  or written instruction
received by the Owner Trustee pursuant to Section 6.03; and no implied duties
or  obligations shall be  read into this  Trust Agreement or  any other Basic
Document against  the  Owner  Trustee.   The  Owner  Trustee  shall  have  no
responsibility for  filing any  financing or  continuation  statement in  any
public office at any time or to otherwise perfect or maintain  the perfection
of  any security interest  or lien granted  to it hereunder or  to prepare or
file any Securities and Exchange Commission filing for the Trust or to record
this Trust Agreement or any  Basic Document.  The Owner Trustee  nevertheless
agrees that it will, at its own cost and expense, promptly take all action as
may be necessary to  discharge any liens on any part of the Trust Estate that
result from actions  by, or claims against,  the Owner Trustee solely  in its
individual  capacity   that  are  not   related  to  the  ownership   or  the
administration of the Trust  Estate.  Without limiting the generality  of the
foregoing, the  Owner Trustee shall take only such  action with respect to an
Event of Default pursuant to the terms of the Basic Documents.

                    ---------------------------------------------

dispose of or otherwise deal with any  part of the Trust Estate except (i) in
accordance with the  powers granted to and  the authority conferred  upon the
Owner Trustee pursuant  to this Trust Agreement, (ii) in  accordance with the
Basic  Documents  and (iii) in  accordance with  any document  or instruction
delivered to the Owner Trustee pursuant to Section 6.03.

     Section 6.06.  Restrictions.  The Owner Trustee shall not take any
                    ------------
action (a) that  is inconsistent with the purposes of  the Trust set forth in
Section 2.03 or (b) that, to the actual knowledge of the Owner Trustee, would
result in the  Trust's becoming taxable  as a corporation for  federal income
tax purposes.  The  Certificateholders shall not direct the  Owner Trustee to
take action that would violate the provisions of this Section 6.06.

     Section 6.07.  Limitation on Trust Activities.  Notwithstanding any
                    ------------------------------
other provision in this  Trust Agreement to  the contrary, the Owner  Trustee
shall have  no power  to exercise discretion  to vary  the investment  of the
Certificateholders  within  the meaning  of  Treasury  Department Regulations
Section 301.7701-4(c), or to engage in any business activity unless the Owner
Trustee  shall have received  an Opinion of Counsel  that such activity shall
not adversely affect  the status of the  Trust as a security  arrangement for
the issuance of debt. 

     Section 6.08.  No Consent to Certain Acts of Depositor.  The Owner
                    ---------------------------------------
Trustee shall not consent to any action proposed to be taken by the Depositor
pursuant to  Article EIGHTH or  Article ELEVENTH of the  Depositor's Restated
Certificate of Incorporation.

reasonable grounds  for believing  that repayment of  such funds  or adequate
indemnity  against  such risk  or  liability  is  not reasonably  assured  or

the request, order or direction of any of the Certificateholders, unless such
Certificateholders have  offered to the  Owner Trustee security  or indemnity

     Section 9.01.  Termination of Trust Agreement.  (a)  This Trust
                    ------------------------------
Agreement  (other than Article VIII) and the Trust  shall terminate and be of
no further force or  effect upon the final distribution by  the Owner Trustee
of all moneys or other property or proceeds of the Trust Estate in accordance
with the terms of the Indenture and Article V.  The  bankruptcy, liquidation,
dissolution,  death  or   incapacity  of  any  Certificateholder   shall  not
(x) operate to  terminate this  Trust Agreement or  the Trust  or (y) entitle
such Certificateholder's legal representatives or  heirs to claim an account-
ing  or to  take any action  or proceeding  in any  court for a  partition or
winding up of all or  any part of the Trust or Trust  Estate or (z) otherwise
affect the rights, obligations and liabilities of the parties hereto.

     (b)  None of the  Depositor, or any Certificateholder  shall be entitled
to revoke or terminate the Trust.

     (c)  Notice of any termination of the Trust, specifying the Payment Date
upon  which  Certificateholders  shall surrender  their  Certificates  to the
Administrator for payment of  the final distribution and  cancellation, shall
be given by  the Owner Trustee by letter to  Certificateholders mailed within
five Business Days prior  to the final Payment Date, stating  (i) the Payment
Date upon or with respect to which final payment of the Certificates shall be
made upon presentation and surrender of the Certificates at the office of the
Administrator therein designated, (ii) the amount  of any such final  payment
and  (iii) that the Record Date otherwise applicable  to such Payment Date is
not applicable, payments  being made only upon presentation  and surrender of
the Certificates at the office  of the Administrator therein specified.   The
Owner Trustee  shall give such notice to  the Certificate Registrar (if other
than  the Owner Trustee) and the Administrator, the Swap Counterparty and the
Swap Guarantor at the time such notice is given to Certificateholders.   Upon
presentation and surrender of the Certificates, the Administrator shall cause
to be distributed to Certificateholders amounts distributable on such Payment
Date pursuant to Section 5.02.

     In  the event  that all  of the  Certificateholders shall  not surrender
their  Certificates  for  cancellation  within  six  months  after  the  date
specified in the above mentioned written notice, the Owner Trustee shall give
a  second written  notice  to the  remaining Certificateholders  to surrender
their Certificates for  cancellation and receive the final  distribution with
respect thereto.   If within one  year after the  second notice all  the 
Certificates shall not have been surrendered for  cancellation, the Owner 
Trustee may take appropriate steps, or  may appoint  an agent  to take  
appropriate steps,  to contact  the  remaining Certificateholders concerning
surrender  of  their Certificates, and the cost  thereof shall be paid out 
of the  funds and other assets  that  shall  remain  subject to  this  Trust
Agreement.   Any  funds remaining in the Trust after exhaustion of such 
remedies shall be distributed by the Owner Trustee to the Depositor.

     (d)  Upon the  winding up of  the Trust and  its termination, the  Owner
Trustee shall cause  the Certificate  of Trust  to be cancelled  by filing  a
certificate of  cancellation with the  Secretary of State in  accordance with
the provisions of Section 3810 of the Business Trust Statute.

     Section 10.01. Eligibility Requirements for Owner Trustee.  The Owner
                    ------------------------------------------
Trustee shall  at all  times be  a corporation  satisfying the  provisions of
Section 3807(a)  of  the  Business  Trust  Statute;  authorized  to  exercise
corporate trust  powers; having a  combined capital and  surplus of  at least
$50,000,000 and  subject to  supervision or examination  by federal  or state
authorities; and having  (or having a parent  that has) a rating  of at least
Baa3 by Moody's  (or a rating otherwise  acceptable to Moody's) and  at least
BBB- by S&P.  If such corporation shall publish reports of condition at least
annually pursuant to law or to the requirements  of the aforesaid supervising
or examining authority,  then for the  purpose of this Section,  the combined
capital and surplus  of such corporation shall  be deemed to be  its combined
capital and  surplus as set forth in  its most recent report  of condition so
published.  In case at any time the Owner Trustee shall cease to be  eligible
in accordance with  the provisions of this  Section 10.01, the Owner  Trustee
shall  resign immediately  in  the manner  and with  the effect  specified in
Section 10.02.

     Section 10.02.  Resignation or Removal of Owner Trustee.  The Owner
                     ---------------------------------------
Trustee may  at any  time resign  and be  discharged from  the trusts  hereby
created  by giving  written notice  thereof  to the  Administrator, the  Swap
Counterparty,  the Swap  Guarantor and  the Depositor.   Upon  receiving such
notice of resignation, the Administrator shall, with the prior consent of the
Swap Counterparty and  the Swap Guarantor promptly appoint  a successor Owner
Trustee by  written instrument,  in duplicate, one  copy of  which instrument
shall  be  delivered to  the  resigning Owner  Trustee  and one  copy  to the
successor Owner Trustee.   If no successor  Owner Trustee shall have  been so
appointed and  have accepted appointment  within 30 days after the  giving of
such  notice of  resignation, the  resigning Owner  Trustee may  petition any
court  of competent  jurisdiction for  the appointment  of a  successor Owner
Trustee.

     If at  any  time  the  Owner  Trustee shall  cease  to  be  eligible  in
accordance  with the  provisions of  Section 10.01 and  shall fail  to resign
after written request  therefor by the Administrator,  or if at any  time the
Owner Trustee shall be legally unable  to act, or shall be adjudged  bankrupt
or insolvent, or a receiver of the Owner Trustee or of its  property shall be
appointed, or any  public officer shall take  charge or control of  the Owner
Trustee or  of its  property or  affairs for the  purpose of  rehabilitation,
conservation or liquidation, then the Administrator, the Swap Counterparty or
the Swap Guarantor may  remove the Owner Trustee.  If  the Administrator, the
Swap Counterparty or the Swap Guarantor shall remove  the Owner Trustee under
the authority of  the immediately preceding sentence, the  Administrator, the
Swap Counterparty  or the Swap  Guarantor shall promptly appoint  a successor
Owner  Trustee  by  written  instrument,  in duplicate,  one  copy  of  which
instrument shall  be delivered to the  outgoing Owner Trustee so  removed and
one copy to the  successor Owner Trustee, and the Administrator  and the Swap
Counterparty shall pay all fees owed to the outgoing Owner Trustee.

     Any  resignation or  removal of the  Owner Trustee and  appointment of a
successor Owner Trustee  pursuant to  any of the  provisions of this  Section
shall not become  effective until acceptance of appointment  by the successor
Owner Trustee pursuant to Section 10.03 and payment of  all fees and expenses
owed to  the outgoing Owner Trustee.   The Administrator shall provide notice
of such  resignation or removal  of the Owner  Trustee to each  of the Rating
Agencies and the Swap Guarantor.

     Section 10.03.  Successor Owner Trustee.  Any successor Owner Trustee
                     -----------------------
appointed pursuant to Section 10.02 shall execute, acknowledge and deliver to
the Administrator, the Swap Counterparty and to its predecessor Owner Trustee
an  instrument  accepting such  appointment under  this Trust  Agreement, and
thereupon the resignation  or removal of the predecessor  Owner Trustee shall
become effective, and such successor  Owner Trustee, without any further act,
deed or conveyance,  shall become fully  vested with all the  rights, powers,
duties and  obligations of its  predecessor under this Trust  Agreement, with
like effect  as if originally named as Owner  Trustee.  The predecessor Owner
Trustee  shall deliver  to  the  successor Owner  Trustee  all documents  and
statements  and  monies  held by  it  under  this  Trust  Agreement; and  the
Administrator and  the predecessor  Owner Trustee  shall execute  and deliver
such instruments and do  such other things as may reasonably  be required for
fully and certainly vesting and confirming in the successor Owner Trustee all
such rights, powers, duties and obligations.

     No successor Owner Trustee shall  accept appointment as provided in this
Section  10.03 unless  at the time  of such  acceptance such  successor Owner
Trustee shall be eligible pursuant to Section 10.01.

     Upon acceptance of appointment by  a successor Owner Trustee pursuant to
this  Section 10.03,  the  Administrator  shall mail  notice  thereof to  all
Certificateholders,  the  Indenture  Trustee,  the  Noteholders,  the  Rating
Agencies  and the Swap  Guarantor.  If  the Administrator shall  fail to mail
such  notice within  10 days  after  acceptance of  such  appointment by  the
successor Owner Trustee, the successor  Owner Trustee shall cause such notice
to be mailed at the expense of the Administrator.

     Section 10.04. Merger or Consolidation of Owner Trustee.  Any Person
                    ----------------------------------------

be  consolidated, or  any Person  resulting  from any  merger, conversion  or
consolidation to  which the  Owner Trustee shall  be a  party, or  any Person
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, without
the  execution or filing of any instrument or  any further act on the part of
any of the  parties hereto, anything herein to  the contrary notwithstanding;
provided, that such  Person shall be eligible pursuant  to Section 10.01 and,
provided, further, that the Owner Trustee shall mail notice of such merger or
consolidation  to the  Rating Agencies,  the Swap  Counterparty and  the Swap
Guarantor.

supplement  any  provisions in  this Trust  Agreement or  for the  purpose of
adding any provisions to or changing in any manner  or eliminating any of the
provisions in  this Trust Agreement or of modifying  in any manner the rights
of the Noteholders  or the Certificateholders;  provided, however, that  such
action shall not,  as evidenced by an Opinion of Counsel, adversely affect in
any  material respect the interests of any Noteholder, Certificateholder, the
Swap Counterparty or the Swap Guarantor.

     This  Trust Agreement  may also  be  amended from  time to  time  by the
Depositor, and  the Owner  Trustee, with prior  written notice to  the Rating
Agencies, with the  consent of the Holders  (as defined in the  Indenture) of
Notes evidencing not less than  a majority of the of Principal Amount  of the

a  majority owning  Voting  Interests,  the Swap  Counterparty  and the  Swap
Guarantor,  for the purpose  of adding any  provisions to or  changing in any
manner or eliminating  any of the  provisions of this  Trust Agreement or  of
modifying   in   any   manner   the   rights   of   the    Noteholders,   the
Certificateholders,  the Swap Counterparty  or the Swap  Guarantor; provided,
however, that no such amendment may (a) increase  or reduce in any manner the
amount of, or accelerate or delay  the timing of, collections of payments  on
CABS or distributions that  shall be required to  be made for the  benefit of
the  Noteholders  or  the  Certificateholders  or  (b) reduce  the  aforesaid
percentage of the  Principal Amount of the  Notes or the Voting  Interests of
the  Certificates required to consent to  any such amendment, without (x) the
consent of the holders of all the  outstanding Notes and Certificates, as the
case may be  and (y) confirmation from each Rating Agency that such amendment
shall not cause  the rating of the Notes  or the Certificates to  be reduced,
suspended or withdrawn.

     Promptly after the execution of any such amendment or consent, the Owner
Trustee shall furnish written notification of the substance of such amendment
or  consent to  each  Certificateholder,  the  Indenture  Trustee,  the  Swap
Counterparty and the Swap Guarantor and each of the Rating Agencies.

     It  shall  not  be  necessary  for  the  consent of  Certificateholders,
Noteholders, the  Indenture  Trustee,  the  Swap  Counterparty  or  the  Swap
Guarantor pursuant  to this Section 11.01  to approve the  particular form of
any proposed amendment or consent, but it shall be sufficient if such consent
shall approve the  substance thereof.  The manner of  obtaining such consents
(and  any other  consents of  Certificateholders provided  for in  this Trust
Agreement or in any other Basic Document) and of evidencing the authorization
of  the execution  thereof by  Certificateholders  shall be  subject to  such
reasonable requirements as the Owner Trustee may prescribe.

     Promptly  after the  execution of  any amendment  to the  Certificate of
Trust, the Owner  Trustee shall cause the  filing of such amendment  with the
Secretary of State of the State of Delaware.

Certificate of Trust, the Owner Trustee shall be entitled to receive and rely
upon an Opinion  of Counsel stating that  the execution of such  amendment is
authorized or permitted by this Trust Agreement.   The Owner Trustee may, but
shall not  be obligated to,  enter into any  such amendment that  affects the
Owner Trustee's own  rights, duties or immunities under  this Trust Agreement
or otherwise. 

     Section 11.02. Voting Interests.  As of any date, the aggregate
                    ----------------
outstanding principal  balance of all Certificates will constitute the voting
interest of the Issuer (the  "Voting Interests"), for purposes of determining
Voting Interests, Certificates owned by the  Issuer or its affiliates and the
Depositor  will be disregarded  and deemed not to  be outstanding, and except
that, in  determining whether the Owner Trustee  is protected in relying upon
any  such request,  demand,  authorization,  direction,  notice,  consent  or
waiver, only Certificates that the Owner Trustee knows to be so owned will be
so disregarded.   Certificates so owned that have  been pledged in good faith
may be regarded as outstanding if the pledgee establishes to the satisfaction
of  the Owner Trustee  the pledgor's  right so  to act  with respect  to such
Certificates and that the pledgee is not the Issuer or its affiliates.

Guarantor,  the  Owner Trustee  may  enter into  any  amendment  of the  Swap
Agreement requested by the Swap Counterparty to cure any ambiguity in,  or to
correct or supplement any  provision of, such Swap Agreement, so  long as the

Counsel, that such amendment  will not adversely affect the interests  of the
Noteholders and the Certificateholders.

Estate.   The Certificateholders  shall be entitled  to receive distributions

otherwise, of any right, title or  interest of the Certificateholders to  and

                    First Payment Date:  October 25, 1997

     This certifies that Cede &  Co.is the registered owner of the  undivided
ownership interest evidenced by this Certificate in the amounts distributable
from a trust (the  "Trust") consisting of CABS and  Eligible Investments with
an  aggregate  outstanding  principal  amount  as  of  the  Closing  Date  of
approximately  $257,735,000 which together with other similar certificates or
notes evidence undivided initial beneficial interests in pools of receivables
generated from  time to time  in portfolios  of revolving  card accounts  and
collections thereon.   The CABS were transferred  to the Trust by  Lehman ABS
Corporation  (the "Depositor").   The Trust  was created pursuant  to a trust
agreement  dated as of September 1, 1997  (the "Trust Agreement") between the
Depositor  and  Wilmington  Trust  Company,  as  owner  trustee  (the  "Owner
Trustee",   which  term  includes  any   successor  entity  under  the  Trust
Agreement), a summary  of certain of the pertinent provisions of which is set
forth hereinafter.   This Certificate is issued  under and is subject  to the
terms,  provisions and  conditions of  the  Trust Agreement,  to which  Trust
Agreement the Holder  of this Certificate by virtue of  the acceptance hereof
assents and by which such Holder is bound. 

     This Certificate  is one  of a duly  authorized issue  of Floating  Rate
Asset-Backed Certificates, Class A2 (herein called the "Certificates") issued
under the Trust Agreement  to which reference is hereby made  for a statement
of the respective  rights thereunder of the Depositor, the  Owner Trustee and
the Holders of the Certificates and the terms upon which the Certificates are
executed and delivered.  All terms used in this Certificate which are defined
in the Trust  Agreement shall have the meanings assigned to them in the Trust
Agreement.  The  terms of this Certificate  are subject to provisions  of the
Trust Agreement, and in case of an  inconsistency between the terms set forth
in this Certificate and those  set forth in the Trust Agreement, those of the
Trust Agreement shall govern.

     The Trust Agreement requires the  distribution on each Payment Date (the
"Payment Date"), commencing on the First Payment Date specified above, to the
Person in whose name this Certificate is  registered at the close of business
on  the  day  immediately  preceding  such Payment  Date  or,  if  Definitive
Certificates are issued,  fifteen days prior  to such Payment Date,  or, with
respect to the First  Payment Date, the Closing Date (the  "Record Date"), of
principal  and interest  in accordance  with the  terms of the  Indenture and
Trust Agreement.

     The  Certificates are  limited  in  right of  payment  to the  ownership
interests represented  hereby in  distributions on the  CABS received  by the
Owner Trustee, all  as more specifically  set forth herein  and in the  Trust
Agreement and  Indenture.  The  Certificateholder, by its acceptance  of this
Certificate, agrees that it  will look solely to the funds  on deposit in the
Collection Account maintained  by the Indenture Trustee and  its rights under
the Swap  Agreement for payment hereunder and  that neither the Owner Trustee
in  its individual  capacity nor  the Depositor is  personally liable  to the
Certificateholders for any amount payable under this Certificate or the Trust
Agreement or, except as expressly provided in the Trust Agreement, subject to
any liability under the Trust Agreement.

     The Holder of  this Certificate acknowledges and agrees  that its rights
to receive distributions  in respect of this Certificate  are subordinated to
the rights  of the  Noteholders as  described in  the Indenture  dated as  of
September  1, 1997  among  the Trust,  The  Bank of  New  York  and the  Swap
Counterparty (the "Indenture").

     Each  Certificateholder or  Certificate  Owner, by  its acceptance  of a
Certificate or, in the case of a Certificate Owner, a beneficial  interest in
a   Certificate,  covenants  and   agrees  that  such   Certificateholder  or
Certificate Owner, as the case may be, will not at any time institute against
the  Depositor, or  join  in any  institution against  the Depositor  of, any
bankruptcy,   reorganization,   arrangement,    insolvency   or   liquidation
proceedings, or  other proceedings under  any United States federal  or state
bankruptcy or similar law  in connection with any obligations relating to the
Certificates, the Notes, the Trust Agreement or any of the Basic Documents.

     Distributions on this Certificate will be made as provided in  the Trust
Agreement  by the  Administrator  by wire  transfer  or check  mailed  to the
Certificateholder  of  record   in  the  Certificate  Register   without  the
presentation or surrender  of this Certificate or the making  of any notation
hereon.  Except  as otherwise provided  in the  Trust Agreement and  notwith-
standing  the above, the final distribution  on this Certificate will be made
after due notice by the Owner Trustee of the pendency of such distribution as
provided in the Trust Agreement  and only upon presentation and  surrender of
this Certificate as provided for in the Trust Agreement.

     Reference is hereby  made to the further provisions  of this Certificate
set forth  on the  reverse hereof,  which further  provisions  shall for  all
purposes have the same effect as if set forth at this place.

     Unless the certificate of authentication hereon shall have been executed
by an authorized  officer of the Owner Trustee, or an authenticating agent by
manual signature, this Certificate shall not entitle the Holder hereof to any
benefit under the Trust Agreement or be valid for any purpose.

     THIS CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH  THE LAWS  OF THE
STATE OF DELAWARE,  AND THE OBLIGATIONS,  RIGHTS AND REMEDIES OF  THE PARTIES
HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.


          IN WITNESS WHEREOF, the  Owner Trustee, on behalf of the  Trust and
not  in its  individual  capacity, has  caused  this Certificate  to be  duly
executed.

                           (REVERSE OF CERTIFICATE)


     The Certificates do  not represent an obligation of, or  an interest in,
the Depositor, the Seller, the Owner Trustee, the Swap Counterparty, the Swap
Guarantor or any affiliates of any of them (except the Trust) and no recourse
may  be had  against such parties  or their  assets, except as  expressly set
forth  or contemplated herein  or in the  Trust Agreement or  the other Basic
Documents.    In  addition,  this   Certificate  is  not  guaranteed  by  any
governmental agency or instrumentality and is  limited in right of payment to
certain  collections and  recoveries with  respect to  the CABS  (and certain
other amounts),  all as more  specifically set forth herein.   A copy  of the
Trust Agreement may be examined by any Certificateholder upon written request
during normal business hours at the principal office of the Depositor  and at
such other places, if any, designated by the Depositor.

     The Trust Agreement  permits, with certain exceptions  therein provided,
the amendment thereof  and the modification of the  rights and obligations of
the  Depositor and  the  rights  of the  Certificateholders  under the  Trust
Agreement at any time by the Depositor and the Owner Trustee with the consent
of  the  Swap Counterparty,  the Swap  Guarantor  and of  the Holders  of the
Certificates and the Noteholders, each voting as a class, evidencing not less
than  a  majority  of  the  Voting  Interests  of  the  Certificates and  the
outstanding principal balance  of the  Notes of  each such class.   Any  such
consent by the  Holder of this Certificate shall be conclusive and binding on
such  Holder  and  on all  future  Holders  of this  Certificate  and  of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof,  whether  or  not  notation  of  such  consent  is   made  upon  this
Certificate.   The  Trust Agreement  also permits  the amendment  thereof, in
certain limited circumstances, without the  consent of the Holders of  any of
the Certificates.

     As provided  in the Trust  Agreement and subject to  certain limitations
therein set forth,  the transfer of  this Certificate is registerable  in the
Certificate Register upon  surrender of this Certificate for  registration of
transfer at the  offices or agencies of the  Certificate Registrar maintained
by the Trust in the Borough of  Manhattan, The City of New York,  accompanied
by a written instrument of transfer in form satisfactory to the Owner Trustee
and the  Certificate Registrar duly  executed by  the Holder  hereof or  such
Holder's attorney duly  authorized in writing, and thereupon  one or more new
Certificates  of  authorized  denominations  evidencing  the  same  aggregate
interest in  the Trust  will be  issued to  the designated  transferee.   The
initial Certificate Registrar appointed under the Trust Agreement is The Bank
of New York.

     Except as provided in the Trust Agreement, the Certificates are issuable
only in minimum denominations of $100,000 and in integral multiples of $1,000
in excess thereof.  As provided in the Trust Agreement and subject to certain
limitations   therein  set  forth,  Certificates  are  exchangeable  for  new
Certificates  of  authorized  denominations  evidencing  the  same  aggregate
denomination, as requested  by the Holder surrendering the  same.  No service
charge will be  made for any such  registration of transfer or  exchange, but
the Owner  Trustee or the Certificate Registrar may  require payment of a sum
sufficient  to cover  any tax  or governmental  charge payable  in connection
therewith.

     The  Owner Trustee, the Certificate Registrar and any agent of the Owner
Trustee or the  Certificate Registrar may treat the Person in whose name this
Certificate is  registered as the owner hereof for  all purposes, and none of
the  Owner  Trustee, the  Certificate Registrar  or any  such agent  shall be
affected by any notice to the contrary.

     The obligations and  responsibilities created by the Trust Agreement and
the   Trust   created  thereby   shall   terminate   upon  the   payment   to
Certificateholders of all amounts required to be paid to them pursuant to the
Trust Agreement and the Indenture and the disposition of all property held as
part of the Trust Estate.

     or  Certificateholder,  as  the  case   may  be,  as  being  subject  to
     withholding and backup withholding taxes  and shall retain from  amounts
     otherwise  distributable to such Noteholder or Certificateholder, as the
     case may be, an amount sufficient for the payment of such withholding or
     backup withholding tax (as applicable). 
 
     The Indenture Trustee may  at any time, in connection with obtaining the
satisfaction and  discharge of this  Indenture or  for any other  purpose, by
Issuer  Order direct the  Administrator to pay  to the  Indenture Trustee all
sums  held  in trust  by such  Administrator,  such sums  to be  held  by the
Indenture Trustee upon the same trusts as those upon which the sums were
held by  such Administrator;  and upon  such payment  by the Administrator  
to the Indenture  Trustee, such  Administrator shall  be released  from all  
further liability with respect to such money. 
 
     Section 3.04.  Existence.  The Issuer shall keep in full effect its 
                    --------- 
existence, rights and  franchises as a business  trust under the laws  of the
State of Delaware (unless it becomes, or any successor Issuer hereunder is or
becomes, with  the  prior consent  of  the  Swap Counterparty  and  the  Swap
Guarantor, organized  under the  laws of  any other  state or  of the  United
States  of America, in which  case the Issuer  shall keep in  full effect its
existence, rights and  franchises under the laws of  such other jurisdiction)
and  shall obtain  and  preserve its  qualification to  do  business in  each
jurisdiction in which such qualification is or  shall be necessary to protect
the  validity and enforceability of this  Indenture, the Notes, the CABS, the
Swap  Agreement, the  Swap  Policy  and each  other  instrument or  agreement
included in the Trust Estate. 
 
     Section 3.05.  Application of Trust Funds.  (a)  The Notes shall accrue 
                    -------------------------- 
interest at  the Note Accrual Rate, calculated on the basis of a 360 day year
consisting of twelve 30-day months.  Such amounts shall be due and payable on
each Payment Date.  Interest shall  accrue with respect to each Payment  Date
from and including  the preceding Payment Date  (or in the case of  the first
Payment  Date, from  and including  the Closing Date)  to but  excluding such  
current Payment Date (each, a "Interest Accrual Period").  Interest on the  
                               ----------------------- 
Notes shall be  payable solely  from amounts in  the Collection  Account, inc-
luding mounts received pursuant to the Swap Agreement or the Swap Policy, and 
shall be subject to the Priority of  Payments.  Unless the entire unpaid  
principal amount of the Notes shall  become due and payable  upon the occ-
urrence of  an Event of Default in accordance with the provisions of 
Section 3.05(c) hereof, prior to the  September 1999 Payment Date,  no 
principal shall be  payable on the Notes until the September 1999 Payment 
Date.  Beginning on  the September 1999  Payment Date and on each  Payment 
Date thereafter, principal payable on the Notes  as  described in  Section 
3.05(b)  on any  Payment  Date shall  be calculated by the Calculation Agent, 
and shall be paid to the  Noteholders in accordance with  the Percentage 
Interest  represented by each such  Note. Any Principal Amount of the Notes 
that remains outstanding on the Scheduled Final Payment Date shall be due in  
full on the Scheduled Final Payment Date.   Any installment of interest  or 
principal, if  any, payable on  any Note that  is punctually paid or  duly 
provided for by the Issuer on the applicable Payment Date shall be paid to 
each Noteholder of record on the preceding Record Date, by  wire transfer  
to  an account  specified in  writing  by such  Noteholder reasonably 
satisfactory to  the Indenture Trustee as of  the preceding Record Date or  
by check to  such Noteholder mailed to  such Holder's address  as it appears 
in the Note  Register if no such instructions have  been delivered to
the Indenture Trustee.  
 
     (b)  (i) Principal due on the Notes shall be payable solely from amounts
in the  Collection Account, including  amounts, if any, received  pursuant to
the Swap Agreement or the Swap Policy,  and shall be subject to the  Priority
of  Payments.   Beginning  on the  September  1999 Payment  Date and  on each
Payment Date thereafter, principal payable on  the Notes on any Payment  Date
shall be  equal to the Note Amortization Amount  with respect to such Payment
Date, as determined by the Calculation Agent.   

    (ii) In addition, if the then Principal Amount of the Notes  immediately
after any Payment Date  would be less than  or equal to 10% of  the aggregate
original principal  amount of  the Notes,  the Issuer  shall, subject to  the
Priority of  Payments, prepay 100% of the Principal  Amount of the Notes (and
100%  of  the Face  Amount  of the  Certificates  (as provided  in  the Trust
Agreement)) on such Payment Date (the "Mandatory Prepayment").   
                                       -------------------- 
 
     (iii) The Issuer  has no optional prepayment rights with  respect to the
Notes. 
 
     (iv) In connection  with each prepayment, repayment or  other payment of
principal in respect of the Notes as required by Section 3.05,  the Indenture
Trustee shall instruct the Market Agent to sell  CABS and/or Eligible 
Investments in accordance with the Sale Procedures. 
 
     (v) In the event that a  CABS Early Amortization Event has occurred,  if
the Trust receives proceeds from any CABS in  an amount that is less than the
face amount of such CABS (a "Credit Loss"), pursuant to the Trust Agreement, 
                             ----------- 
the Face  Amount of the  Certificates will be  reduced by the amount  of such
Credit Loss until it is reduced to zero.  In the event  that such Credit Loss
is greater than  the Face Amount of the Certificates, the Principal Amount of
the  Notes will  be reduced  (in accordance  with their  respective  Pro Rata
Shares) by any  remaining amount  of such  Credit Loss.   Any such  principal
reduction  will not be  reinstated.  It  is understood  and acknowledged that
such  reduction of the  Principal Amount of  the Notes shall  be effective to
reduce the outstanding principal amount of each Note, and that all references
to Principal Amount, principal amount, outstanding principal amount and other
references to the principal due in respect of a Note or the Notes shall  take
into effect to such reduction.  Similarly,  it is understood and acknowledged
that the  above-referenced reduction of  the Face Amount of  the Certificates
shall be effective  under the Trust Agreement to  reduce the outstanding face
amount of  each Certificate,  and that  all references to  Face Amount,  face
amount, principal amount,  outstanding principal amount and  other references
to the principal  due in respect of  a Certificate or the  Certificates shall
take into effect to such reduction. 
 
     (vi)  The Calculation Agent shall  calculate the PSA  Index Rate and the
Monthly  Amortization  Rate on  the Prepayment  Determination Date  and shall
promptly notify the  Indenture Trustee, the Administrator as  provided in the
Trust Agreement, the Swap Counterparty and the  Swap Guarantor of the results
thereof.   The determination of the  PSA Index Rate, the Monthly Amortization
Rate,  the Note Amortization  Amount and the  Principal Amount of  Notes each
month as provided herein shall, absent manifest error, be final and binding. 
 
     (vii) The Calculation Agent reserves  the right to determine whether any
modification  in PSA  methodology or  in the  timing or  procedures affecting
publication or  dissemination of  the PSA prepayment  rate for  the Reference
Collateral  Pool  warrants   an  adjustment  to  the   foregoing  calculation
procedures, whereupon  such procedures  shall be deemed  to be amended  as so
determined by the Calculation Agent; provided that no change in such 
                                     -------- 
procedures  shall  be effective  without  the  written  consent of  the  Swap
Counterparty and the Swap Guarantor. 
 
     (c)  Upon the occurrence and continuance  of any Event of Default (other
than one specified in clause  (d), (e) or (g) of  the definition of Event  of
Default), the Indenture Trustee, upon  the written request of the Holders  of
not less than a  majority of the then  Principal Amount of the Notes  (or, in
the case of an  Event of Default  described in clause  (c) in the  definition
thereof,  all   Securityholders),  shall,  by   notice  in  writing   to  all
Securityholders,  the Swap Counterparty  and the Swap  Guarantor, declare the
principal  of all Notes then Outstanding (if  not then due and payable) to be
due and payable immediately, and upon such declaration the  same shall become
and be immediately due and payable, anything contained in the Notes or in the
Basic  Documents  to the  contrary  notwithstanding.   Immediately  upon such
declaration, the Indenture Trustee  shall direct the Market Agent to sell and
liquidate  the CABS  and Eligible  Investments  in accordance  with the  Sale
Procedures  and the  Calculation  Agent  shall  calculate  the  Distributable
Amount. Such declaration shall also be effective under and as provided in the
Trust Agreement to cause the entire Face Amount of the Certificates to
become similarly due and payable, subject to the Priority of Payments. 
 
     At any time after such declaration of  acceleration of maturity has been
made and before a  judgment or decree for payment  of the money due has  been
obtained by the Indenture Trustee, the Noteholders representing a majority of
the  then  Principal  Amount of  the  Notes,  with the  consent  of  the Swap
Counterparty and the Swap Guarantor, by written  notice to the Issuer and the
Indenture  Trustee,   may  rescind  and   annul  such  declaration   and  its
consequences if: 
 
          (i)  the Issuer has paid or  deposited with the Indenture Trustee a
     sum sufficient to pay: 
 
               (A)  all   payments  of  principal  of  and  interest  on  the
          Securities and all  other amounts that would then  be due hereunder
          and otherwise  upon the Securities  if the Event of  Default giving
          rise to such acceleration had not occurred; 
 
               (B)  all  amounts due to the  Swap Counterparty under the Swap
          Agreement or the Swap Guarantor; and 
 
         (ii)  all  Events of  Default,  other  than  the nonpayment  of  the
     principal  of  the  Securities  that  has  become  due  solely  by  such
     acceleration, have been cured or waived as provided in Section 5.11. 

     Such rescission  shall also be  effective under and  as provided  in the
Trust Agreement  to rescind and annul the declaration  of an Event of Default
and acceleration of the Face Amount of the Certificates as provided therein. 
 
     No such  rescission shall  affect any subsequent  default or  impair any
right consequent thereto. 
 
     The entire unpaid principal amount of the Notes shall become immediately
due  and payable  automatically upon  the occurrence  of an Event  of Default
specified in clause (d), (e) or  (g) of the definition thereof.   Immediately
after  the occurrence of an Event of Default  described in clause (d), (e) or
(g) of the definition of Event of Default, the Indenture Trustee shall direct
the Market Agent to sell and  liquidate the CABS and Eligible Investments  in
accordance with the Sale Procedures and the Calculation Agent shall calculate
the Distributable Amount. 
 
     Any amounts  in  respect of  the  Notes not  paid  when due  under  this
Indenture  (including  any overdue  interest) shall  accrue interest,  to the
extent permitted by  applicable law, at the  Note Accrual Rate until  paid as
provided in this Indenture. 
 
     (d)  The Indenture Trustee  shall apply all monies received  by it under
this Trust  Indenture, including proceeds  of the CABS, proceeds  of Eligible
Investments, payments made  by the Swap Counterparty to  the Issuer under the
Swap Agreement,  payments made  by the  Swap Guarantor pursuant  to the  Swap
Policy, amounts  realized by  the Indenture  Trustee upon  the sale or  other
liquidation  of  CABS or  Eligible  Investments  and  proceeds of  any  other
property  included in  the  Trust  Estate in  accordance  with the  following

          SIXTH:    to the  Swap Counterparty, if  there shall be  any excess

              The Notes; Satisfaction and Discharge of Indenture 
             -------------------------------------------------- 

     Section 4.01.  The Notes.  The aggregate Denominations of all Notes 
                   --------- 
ssued as of the Closing Date shall be $250,000,000.  Beneficial Owners shall
hold interests in  the Global Notes through the book-entry  facilities of the
Depository  in minimum  Denominations  of $10,000  and integral  multiples of
$1,000 in excess thereof. 

    All Notes shall be issued initially in the form of one or more permanent
Global  Notes in definitive,  fully registered form  without interest coupons
with the applicable legend set forth in Exhibit A hereto, respectively, added
to the form of such Notes (each, a "Global Note"), which shall be deposited 
                                   ----------- 
n behalf  of the  subscribers for  such Notes represented  thereby with  the
Indenture Trustee as custodian  for the Depository and registered in the name
of  a nominee  of the  Depository,  duly executed  by the  Owner  Trustee and
authenticated  by  the  Indenture  Trustee  as  hereinafter  provided.    The
aggregate principal  amount of  the Global  Notes may  from time  to time  be
increased  or decreased by adjustments  made on the  records of the Indenture 
Trustee or the Depository or  its nominee, as the case may be, as hereinafter
provided. 

    The  Indenture Trustee  may for  all purposes  (including the  making of
payments due on  the Global Notes) deal with the Depository as the authorized
representative of  the Beneficial Owners with respect to the Global Notes for
the purposes of exercising  the rights of Noteholders  hereunder.  Except  as
provided in the next succeeding paragraph of this Section 4.01, the rights of
Beneficial Owners with respect to the Global Notes shall be limited  to those
established  by law  and agreements  between such  Beneficial Owners  and the
Depository and Depository Participants.   Except as provided in Section 4.08,
Beneficial Owners shall  not be entitled to  definitive notes for  the Global
Notes as to  which they are the  Beneficial Owners.  Requests  and directions
from,  and  votes  of, the  Depository  as  Noteholder  shall  not be  deemed
inconsistent if  they are made  with respect to different  Beneficial Owners.
The Indenture  Trustee may establish  a reasonable record date  in connection
with solicitations  of consents from or voting by Noteholders and give notice
to the Depository of such record date.  Without the consent of the Issuer and
the Indenture  Trustee, no Global Note  may be transferred by  the Depository
except to a successor Depository that agrees to hold such Global Note for the
account of the Beneficial Owners. 

    In the  event The  Depository Trust  Company resigns  or  is removed  as
Depository,  the  Depositor  may  appoint  a successor  Depository.    If  no
successor Depository has been appointed within 30  days of the effective date
of the  Depository's resignation or  removal, each Beneficial Owner  shall be
entitled to certificates representing the Global Note it beneficially owns in
the manner prescribed in Section 4.08. 

    The Notes  shall, on original issue, be executed  on behalf of the Trust
by the Owner  Trustee, not  in its  individual capacity but  solely as  Owner
Trustee,  authenticated  by  the  Indenture  Trustee  and  delivered  by  the
Indenture  Trustee to or  upon the  order of the  Issuer upon receipt  by the
Indenture Trustee of the CABS.

- -------- 
Trusts  Corporate  Trust Office  a  note  register  in  which, subject  to  such
reasonable regulations as it may  prescribe, the Note Registrar shall provide
for the registration  of Notes  and of  transfers and exchanges  of Notes  as
herein provided (the "Note Register"). 
                      ------------- 
 
     Subject  to  the restrictions  and  limitations  set forth  below,  upon
surrender for  registration of transfer  of any Note  at the  Corporate Trust
Office,  the Indenture  Trustee shall  execute and  the Note  Registrar shall
authenticate  and  deliver, in  the  name  of  the designated  transferee  or
transferees, one or more new Notes in authorized Denominations evidencing the
same aggregate Percentage Interests. 
 
     At the option of the Noteholders, Notes may be exchanged for other Notes
in  authorized  Denominations  evidencing   the  same  aggregate   Percentage
Interests upon surrender  of the Notes to be exchanged at the Corporate Trust
Office of  the Note  Registrar.  Whenever  any Notes  are so  surrendered for
exchange, the Owner  Trustee on behalf  of the Issuer  shall execute and  the
Indenture  Trustee  shall  authenticate  and  deliver  the  Notes  which  the
Noteholder making the  exchange is entitled to receive.   Each Note presented
or  surrendered  for registration  of  transfer  or  exchange shall  be  duly
endorsed by, or  be accompanied by a  written instrument of transfer  in form
reasonably satisfactory  to the Note  Registrar duly executed by,  the Holder
thereof or his attorney duly authorized in writing.  Notes delivered upon any
such transfer or exchange  shall evidence the same obligations,  and shall be 
entitled to the same rights and privileges, as the Notes surrendered. 
 
     No service charge  shall be  made for  any registration  of transfer  or
exchange of Notes,  but the  Note Registrar  shall require payment  of a  sum
sufficient to  cover any tax  or governmental charge  that may be  imposed in
connection with any registration of transfer or exchange of Notes. 
 
     All Notes surrendered for registration of transfer and exchange shall be
cancelled by  the Note Registrar and delivered   to the Indenture Trustee for
subsequent destruction without liability on the part of either. 
 
     Section 4.03.  Mutilated, Destroyed, Lost or Stolen Notes.  If (i) any 
                    ------------------------------------------ 
mutilated Note is  surrendered to the Note  Registrar, or the Note  Registrar
receives evidence  to its satisfaction  of the destruction, loss  or theft of
any Note, and (ii) there is delivered to the Indenture Trustee such  security
or indemnity as may be required by it to hold the Issuer, the Note  Registrar
and  the Indenture Trustee  harmless, then, in  the absence of  notice to the
Issuer, the Note Registrar  or the Indenture Trustee that such  Note has been
acquired  by a bona  fide purchaser,  and provided  that the  requirements of
Section 8-405  of the  UCC  are  met,  the Issuer,  shall  execute,  and  the
Indenture  Trustee shall authenticate and deliver, in exchange for or in lieu
of any such  mutilated, destroyed, lost or stolen Note, a replacement Note of
like tenor (including the same date  of issuance) and equal principal amount,
provided that if any such destroyed, lost or stolen Note, but not a mutilated
Note, shall  have become or  within seven days  shall be due  and payable, or
shall have been called for redemption, instead of issuing a replacement Note,
the Issuer may pay such destroyed, lost or stolen Note when so due or payable
or  upon  the  Redemption Date  without  surrender  thereof.   If,  after the
delivery of  such replacement Note or payment of  a destroyed, lost or stolen
Note pursuant to the proviso to the preceding sentence, a bona fide purchaser
of the  original  Note in  lieu of  which such  replacement  Note was  issued
presents for payment such  original Note, the Issuer, the  Note Registrar and
the Indenture Trustee  shall be entitled to recover such replacement Note (or
such payment) from the  Person to whom it was delivered  or any Person taking
such replacement Note  from such  Person to  whom such  replacement Note  was
delivered or any assignee  of such Person, except a bona  fide purchaser, and
shall be entitled to recover upon the security or indemnity provided therefor
to the extent of  any loss, damage, cost or  expense incurred by the  Issuer,
the Note Registrar or the Indenture Trustee in connection therewith. 

    Upon the issuance  of any replacement Note under  this Section 4.03, the
Indenture Trustee may require the payment by the Holder of such Note of a sum
sufficient to cover  any tax or other governmental charge that may be imposed
in relation thereto and any other reasonable expenses (including the fees and
expenses of the Indenture Trustee or the Note Registrar) connected therewith.
 
     Every  replacement  Note  issued  pursuant  to  this   Section  4.03  in
replacement of any mutilated, destroyed, lost or stolen Note shall constitute
an original additional  contractual obligation of the Issuer,  whether or not
the  mutilated,  destroyed,  lost  or  stolen  Note  shall  be  at  any  time
enforceable by anyone,  and shall  be entitled  to all the  benefits of  this
Indenture  equally and  proportionately with  any  and all  other Notes  duly
issued hereunder. 

    The provisions of this Section 4.03 are exclusive and shall preclude (to
the  extent  lawful) all  other  rights  and  remedies  with respect  to  the
replacement or payment of mutilated, destroyed, lost or stolen Notes.

Note Registrar and  any agent of the Issuer, the Note Registrar or the Inden-
ture Trustee shall treat the Person in whose  name any Note is registered (as

receiving payments of principal of and interest, if any, on such Note and
or all other  purposes whatsoever,  whether or  not such  Note  be overdue,  
and neither the Issuer,  the Indenture Trustee, the Note Registrar  nor any 
agent of the Issuer, the Note Registrar or the Indenture Trustee shall  be 
affected by notice to the contrary.

previously  authenticated and delivered  hereunder which the  Issuer may have
acquired  in any  manner  whatsoever, and  all Notes  so  delivered shall  be
promptly cancelled by the Indenture Trustee.  No Notes shall be authenticated
in lieu of or in exchange for any Notes cancelled as provided in this Section
4.05, except as  expressly permitted by this Indenture.   All cancelled Notes
may be held  or disposed of by  the Indenture Trustee in  accordance with its
standard retention or  disposal policy as in  effect at the time,  unless the

of Cede & Co., the nominee of the initial Depository, and no Beneficial Owner
shall receive a Definitive Note representing such Beneficial Owner's interest
in  such  Note,  except  as  provided  in  Section 4.08.   Unless  and  until
definitive, fully registered Notes (the "Definitive Notes") have been issued 
                                         ----------------

          (i)  the provisions of this Section 4.06 shall be in full force and
     effect; 
 
         (ii)  the Note Registrar and the Indenture Trustee shall be entitled
     to  deal  with  the  Depository  for  all  purposes  of  this  Indenture

     Owners  and/or   Depository   Participants   owning   or   representing,
     respectively, such required percentage of the beneficial interest in the

     Section 4.08.  Definitive Notes.  If (i) the Administrator advises the 
                    ---------------- 
Indenture Trustee in writing that the Depository is no longer willing or able
to properly discharge  its responsibilities with respect to  the Global Notes
and the  Administrator is  unable to locate  a qualified  successor, (ii) the
Administrator at its  option advises the Indenture Trustee in writing that it
elects  to  terminate  the  book-entry system  of  registration  through  the
Depository  or  (iii)  after the  occurrence  of  an  Event  of Default,  the
Noteholders evidencing not less than 50% of the then  Principal Amount advise
the Indenture Trustee  and the Depository through Depository  Participants in
writing that the  continuation of a book-entry system  through the Depository
is no longer  in the best interests  of the Noteholders, then  the Depository
shall be  expected to  notify all  Beneficial Owners  of the  availability of

the Notes shall qualify  as indebtedness.  The Issuer, by  entering into this
Indenture,  and  each Noteholder,  by its  acceptance of  its Note  (and each
Beneficial Owner  by its acceptance  of an interest  in the  applicable Book-
Entry Note), agree  to treat the Notes  for federal, state and  local income,
single business and franchise tax purposes as indebtedness.

     discharge  of this Indenture have been complied with and such Opinion of
     Counsel shall further be to the effect that such deposit shall  not have

     any Certificateholders, the Swap Counterparty or the Swap Guarantor.

     Upon any such  waiver, any Event  of Default arising therefrom  shall be
deemed to have been cured and not to have occurred, for every purpose of this
Indenture; but no such waiver shall  extend to any subsequent or other  Event
of Default or impair any right consequent thereto.

                    --------------------- 
agree, and each Holder of any Note  by such Holder's acceptance thereof shall
be deemed  to have agreed, that any  court may in its  discretion require, in
any suit for  the enforcement of any right or remedy under this Indenture, or
in any suit against  the Indenture Trustee for any action  taken, suffered or
omitted by it as Indenture Trustee, the filing by any party litigant in  such
suit of an undertaking to pay the costs of such suit, and that such court may 
in  its discretion assess  reasonable costs, including  reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard

litigant; but the provisions of this Section  5.12 shall not apply to (a) any
suit instituted by the Indenture Trustee, (b) any suit instituted by the Swap

instituted by any Noteholder for the enforcement of  the payment of principal

     Section 5.13.  Waiver of Stay or Extension Laws.  The Issuer covenants 
                    -------------------------------- 
(to the  extent that it  may lawfully do  so) that it  shall not at  any time
insist upon,  or plead or in any manner whatsoever, claim or take the benefit
or advantage of,  any stay or extension  law wherever enacted, now  or at any
time hereafter  in force,  that may  materially affect  the covenants or  the
performance of this  Indenture; and  the Issuer  (to the extent  that it  may
lawfully do so)  hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not hinder, delay or impede the execution of
any power  herein granted  to the  Indenture  Trustee, but  shall suffer  and
permit  the execution  of every such  power as  though no  such law  had been
enacted. 
 
     Section 5.14.  Action on Notes.  The Indenture Trustee's right to seek 
                    --------------- 
and recover judgment on the Notes, in respect of the Swap Agreement, the Swap
Policy or  under  this  Indenture  shall  not be  affected  by  the  seeking,
obtaining or application  of any other relief  under or with respect  to this
Indenture.  Neither the lien of this Indenture nor any rights or  remedies of
the  Indenture Trustee,  the Swap  Counterparty,  the Swap  Guarantor or  the
Noteholders  shall  be  impaired by  the  recovery  of  any judgment  by  the
Indenture Trustee against  the Issuer or by  the levy of any  execution under
such judgment  upon any portion of the Trust Estate or upon any of the assets
of the  Issuer.   Any money or  property collected  by the  Indenture Trustee
shall be applied in accordance with Section 3.05(d).

                    ------------ 
Eligible Investments  by the Indenture  Trustee (or  the Market Agent  on the
Indenture Trustee's behalf)  shall be conducted by the  Indenture Trustee (or
the Market Agent  on the Indenture  Trustee's behalf) in accordance  with the
Sale Procedures.   The settlement of the sale  shall occur no later  than the
close  of business on the Business Day  prior to the related Payment Date or,
if earlier,  on  the date  (and  the time  (if  any))  provided in  the  Swap
Agreement.  

                                 ARTICLE VI 
 
                            The Indenture Trustee 
                            --------------------- 
 
     Section 6.01.  Duties of Indenture Trustee.  (a)  If an Event of Default
                    --------------------------- 
has  occurred and  is continuing,  the Indenture  Trustee shall  exercise the
rights and powers vested  in it by this Indenture and use  the same degree of
care and skill in  their exercise as a  prudent person would exercise or  use
under the circumstances in the conduct of such person's own affairs. 
 
     (b)  Except during the continuance of an Event of Default: 

         (i)  the  Indenture Trustee undertakes  to perform such  duties and
     only such duties as are specifically set  forth in this Indenture and no
     implied covenants  or  obligations shall  be  read into  this Indenture 
     against the Indenture Trustee; and  

        (ii)  in the absence of bad faith on its part, the Indenture Trustee
     may  conclusively rely,  as  to the  truth  of  the statements  and  the
     correctness  of the  opinions expressed  therein,  upon certificates  or
     opinions  furnished  to the  Indenture  Trustee  and conforming  to  the
     requirements of  this Indenture;  however, the  Indenture Trustee  shall
     examine the certificates  and opinions to determine whether  or not they
     conform to the requirements of  this Indenture (but need not confirm  or
     investigate the  accuracy of  mathematical calculations  or other  facts
     stated therein).  
 
     (c)  The Indenture  Trustee may not  be relieved from liability  for its
own negligent  action, its own  negligent failure to  act or its  own willful
misconduct, except that: 

         (i)  this  paragraph does not limit the  effect of paragraph (b) of
     this Section 6.01; 

        (ii)  the Indenture  Trustee shall  not be liable  for any  error of
     judgment made in good faith by a Responsible Officer unless it is proved
     that the  Indenture Trustee was negligent in  ascertaining the pertinent
     facts; and 

       (iii)  the Indenture Trustee shall not  be liable with respect to any
     action it takes  or omits  to take in  good faith  in accordance with  a
     direction received by it pursuant to the this Indenture. 

    (d)  Every provision of this  Indenture that in any  way relates to  the
Indenture Trustee is  subject to paragraphs (a), (b) and (c)  of this Section

    (e)  The Indenture Trustee shall not be liable for interest on any money
received  by it except as the Indenture Trustee may agree in writing with the
Issuer. 

    (f)  No provision of  this Indenture shall require the Indenture Trustee
to expend or risk its own funds or otherwise incur financial liability in the
performance  of any of its duties hereunder or  in the exercise of any of its
rights  or  powers,  if it  shall  have  reasonable grounds  to  believe that
repayment of such funds or adequate  indemnity against such risk or liability
is not reasonably assured to it. 

    Section 6.02.  Rights of Indenture Trustee.  (a)  The Indenture Trustee 
                   --------------------------- 
may rely conclusively  and shall be protected   in acting or  refraining from
acting upon any document believed by it to be genuine and to have been signed
or  presented  by  the  proper  Person.    The  Indenture  Trustee  need  not
investigate any fact or matter stated in the document. 

    (b)  The  Indenture Trustee  may execute  any  of the  trusts or  powers
hereunder or  perform any duties hereunder  either directly or by  or through
agents  or attorneys or  a custodian  or nominee,  and the  Indenture Trustee
shall not be responsible for any misconduct or negligence on  the part of, or
for  the supervision  of,  any  such agent,  attorney,  custodian or  nominee
appointed with due care by it hereunder. 

    (c)  The Indenture Trustee shall  not be liable for any action  it takes
or omits to take  in good faith which it believes to  be authorized or within
its rights or powers; provided that the Indenture Trustee's conduct does not 
                     -------- 
onstitute willful misconduct, negligence or bad faith. 

    (d)  The Indenture Trustee  may consult with  counsel of its  selection,
and the advice or opinion of counsel shall be full and complete authorization
and  protection from  liability in  respect to any  action taken,  omitted
suffered by  it hereunder in good faith and  in accordance with the advice or
opinion of such counsel. 
 
     (e)  Any  request or direction of  the Issuer mentioned herein  shall be
sufficiently evidenced by a Issuer Request or Issuer Order. 
 
     (f)  Whenever  in the  administration of  this  Indenture the  Indenture
Trustee shall deem  it desirable that a matter be proved or established prior
to taking, suffering or omitting  any action hereunder, the Indenture Trustee
(unless other evidence be herein specifically prescribed) may, in the absence
of bad faith on its part, conclusively rely upon an Officers' Certificate. 
 
     (g)  The Indenture Trustee shall be  under no obligation to exercise any
of the  rights or powers  vested in it  by this Indenture  at the request  or
direction  of any of the Noteholders  pursuant to this Indenture, unless such
Noteholders shall have offered  to the Indenture Trustee  reasonable security
or  indemnity against  the costs,  expenses  and liabilities  which might  be
incurred by it in compliance with such request or direction. 
 
     (h) The Indenture Trustee shall  not be bound to make any  investigation

instrument,  opinion, report,  notice,  request,  direction, consent,  order,
bond,  debenture, note,  other evidence  of  indebtedness or  other paper  or
document, but the Indenture Trustee, in its discretion, may make such further
inquiry  or investigation into  such facts or matters as  it may see fit,  
and, if the Indenture  Trustee  shall   determine  to  make   such  further  
inquiry   or investigation, it  shall be  entitled to  examine the  books and 
records  and premises of the Issuer,  personally or by agent or attorney  at 
the sole cost of the Issuer  and shall incur  no liability or  additional 
liability of  any kind by reason of such inquiry or investigation; 
 
     Section 6.03.  Individual Rights of Indenture Trustee.  The Indenture 
                    -------------------------------------- 
Trustee in  its individual  or any  other capacity  may become  the owner  or
pledgee of Notes  and may otherwise  deal with the  Issuer or its  Affiliates
with the  same rights it would  have if it  were not Indenture Trustee.   The
Administrator,  Note Registrar  or co-registrar  may  do the  same with  like
rights.  However, the Indenture Trustee must comply with Section 6.11. 

    Section 6.04.  Indenture Trustee's Disclaimer.  The Indenture Trustee 
                   ------------------------------ 
shall not be responsible for and  makes no representation as to the  validity
or  adequacy of this Indenture or the  Notes, it shall not be accountable for
the Issuer's  use  of the  proceeds  from the  Notes,  and  it shall  not  be
responsible for  any  statement of  the Issuer  in the  Indenture  or in  any
document issued  in connection  with the sale  of the Notes  or in  the Notes
other than the Indenture Trustee's certificate of authentication. 

    Unless The Bank of  New York is the Administrator, the Indenture Trustee
shall  not be  deemed to  have notice or  knowledge of  any Event  of Default
(other than as described in clauses  (i) and (ii) of the definition  thereof)
unless a  Responsible Officer assigned to and  working in the Corporate Trust
Department has actual knowledge or has received written notice thereof. 
 
     The  Indenture  Trustee shall  not  be  responsible  for any  errors  or
omissions  contained in  the CABS  Distribution  Date Statements  or for  any
errors or omissions in the statements furnished to any Noteholder pursuant to
Section 3.19 to the  extent such error  or omission results from  information
contained in or omitted from the CABS Distribution Date Statement. 

    Section 6.05.  Notice of Event of Default.  If an Event of Default 
                   --------------------------  
occurs and is continuing and if  it is known to a Responsible Officer of the 
Indenture Trustee, the  Indenture Trustee shall mail to  each Noteholder, the
Swap  Counterparty and  the Swap  Guarantor notice  of the  Event of  Default
within five Business Days after it obtains written notice thereof.  Except in
the case of an Event of Default in payment of principal of or interest on any
Note (including payments pursuant  to the mandatory redemption provisions  of
such  Note),  the  Indenture  Trustee   may  withhold  the  notice  from  the
Noteholders if and so long as a committee of its Responsible Officers in good
faith  determines  that  withholding  the  notice  is  in  the  interests  of
Noteholders. 
 
     Section 6.06.  Reports by Indenture Trustee to Holders.   The Indenture 
                    --------------------------------------- 
Trustee shall deliver to each Noteholder  such information as may be required
to be provided in respect of its Note under the Code. 
 
     Section 6.07.  Compensation and Indemnity.   The Indenture Trustee shall
                    -------------------------- 
receive from Lehman Brothers Inc.  as compensation for its services hereunder
such fees  as have been separately  agreed upon in  writing on or  before the
date  hereof among  the Depositor,  Lehman  Brothers Inc.  and the  Indenture
Trustee.  The Indenture Trustee shall be obligated to perform its obligations
under this  Indenture whether  or not it  actually receives  the compensation
referred to in  the preceding sentence.  The Indenture Trustee agrees that it
shall not  have recourse to  the Issuer  for its compensation  hereunder. The
Indenture  Trustee's  compensation  shall  not  be  limited  by  any  law  on
compensation of  a trustee of  an express trust.   The Issuer  shall or shall
cause the Administrator to reimburse the Indenture Trustee for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection,
in  addition  to the  compensation for  its  services.   Such  expenses shall
include  the reasonable compensation and expenses, disbursements and advances
of the  Indenture Trustee's  agents, counsel, accountants  and experts.   The
Issuer  shall or  shall cause  the Administrator  to indemnify  the Indenture
Trustee against any and all  loss, liability or expense (including attorneys'
fees) incurred by it in connection with  the administration of this trust and
the performance of its duties hereunder.   The Indenture Trustee shall notify
the  Issuer and  the Depositor promptly  of any  claim for which  it may seek
indemnity.  Failure  by the Indenture Trustee to so notify the Issuer and the
Depositor  shall not  relieve the  Issuer  (or Lehman  Brothers Inc.)  of its
obligations hereunder.  The Issuer  shall or shall cause the  Lehman Brothers
Inc. or its designee to  defend any such claim, and the Indenture Trustee may
have separate counsel and the Issuer shall or shall cause the Lehman Brothers
Inc. to  pay the fees and expenses  of such counsel.  Neither  the Issuer nor
the Lehman Brothers Inc. need reimburse any expense or indemnify  against any
loss,  liability or  expense incurred  by the  Indenture Trustee  through the
Indenture Trustee's  own willful  misconduct, negligence or  bad faith.   The
Issuer (and the Indenture  Trustee acting on behalf of the  Issuer) shall not
incur Extraordinary  Expenses unless 100%  of the Securityholders  consent to
provide indemnification for such Extraordinary Expenses. 
 
     Section 6.08.  Replacement of Indenture Trustee.  No resignation or 
                    -------------------------------- 
removal of the Indenture Trustee and  no appointment of a successor Indenture
Trustee shall  become effective  until the acceptance  of appointment  by the
successor Indenture  Trustee pursuant  to this Section 6.08.   The  Indenture
Trustee may  resign at any time by so notifying  the Issuer. The Holders of a
majority in Principal  Amount of the Notes, the Swap Counterparty or the Swap
Guarantor  may remove  the Indenture  Trustee by  so notifying  the Indenture
Trustee and, in the case of such a removal by the Holders, the Swap Counter-
party, and the Swap Guarantor, and the Holders  of a majority in Principal 
Amount of the Notes  with the prior consent of the Swap Counterparty  and  
the  Swap  Guarantor  may  appoint  a successor  Indenture Trustee.  The 
Administrator shall remove the Indenture Trustee if: 
 
          (i)  the Indenture Trustee fails to comply with Section 6.11;  
          (ii)  the Indenture Trustee is adjudged a bankrupt or insolvent; 
         (iii)  a  receiver  or  other  public officer  takes  charge  of  the

     Indenture Trustee or its property; or 
 
         (iv)  the Indenture Trustee otherwise becomes incapable of acting. 
      If the Indenture Trustee resigns or is removed or if a vacancy exists in
the office of Indenture Trustee for any reason (the Indenture Trustee in such
event being referred to herein as the retiring Indenture Trustee), the Issuer
(with the prior consent of the Swap Counterparty and the Swap Guarantor), may
appoint a successor Indenture Trustee. 
 
     A successor Indenture Trustee shall  deliver a written acceptance of its
appointment to the  retiring Indenture Trustee and the  Swap Counterparty and
the Swap  Guarantor.  Thereupon  the resignation or  removal of  the retiring
Indenture Trustee shall become effective, and the successor Indenture Trustee
shall have all the rights, powers  and duties of the Indenture Trustee  under
this Indenture.   The successor Indenture Trustee shall  mail a notice of its
succession to  Noteholders and the  Rating Agencies.  The  retiring Indenture
Trustee shall promptly transfer all property held by  it as Indenture Trustee
to the successor Indenture Trustee. 
 
     If a  successor Indenture  Trustee does not  take office within  60 days
after  the retiring  Indenture Trustee  resigns or  is removed,  the retiring
Indenture Trustee, the  Issuer, the Swap Counterparty, the  Swap Guarantor or
the Holders of  a majority in Principal Amount of the  Notes may petition any
court of competent jurisdiction for  the appointment of a successor Indenture
Trustee. 
 
     If  the  Indenture  Trustee  fails  to comply  with  Section  6.11,  any
Noteholder,  the Swap  Counterparty or  the Swap  Guarantor may  petition any
court of competent jurisdiction for the removal of the Indenture  Trustee and
the appointment of a successor Indenture Trustee. 

     Notwithstanding the  replacement of  the Indenture  Trustee pursuant  to
this Section, the Issuer's obligations under  Section 6.07  shall  continue  for
the benefit  of  the  retiring  Indenture Trustee. 
 
     Section 6.09.  Successor Indenture Trustee by Merger.  If the Indenture 
                    ------------------------------------- 
Trustee  consolidates with,  merges or  converts  into, or  transfers all  or
substantially  all  its  corporate  trust  business  or  assets  to,  another
corporation  or banking association,  the resulting, surviving  or transferee
corporation without any further act shall be the successor Indenture Trustee;
provided that such corporation or banking association shall be otherwise 
- -------- 
qualified  and  eligible under  Section 6.11.   The  Indenture  Trustee shall
provide the  Rating Agencies,  the Swap Counterparty  and the  Swap Guarantor
prior written notice of any such transaction. 
 
     In case at the time  such successor or successors by merger,  conversion
or consolidation to the Indenture Trustee shall succeed to the trusts created
by this Indenture  any of  the Notes  shall have been  authenticated but  not
delivered,  any  such  successor  to  the Indenture  Trustee  may  adopt  the
certificate  of authentication of  any predecessor trustee,  and deliver such
Notes so authenticated; and in case at  that time any of the Notes shall  not
have  been   authenticated,  any  successor  to  the  Indenture  Trustee  may
authenticate such Notes either in the name of any predecessor hereunder or in
the name  of the successor  to the Indenture Trustee;  and in all  such cases
such certificates shall have the full force which it is anywhere in the Notes
or in this  Indenture provided that the certificate of  the Indenture Trustee
shall have.   
 
      Section 6.10. Appointment of Co-Indenture Trustee or Separate Indenture 
                    ---------------------------------------------------------
Trustee.  (a)  Notwithstanding any other provisions of this Indenture, at any
- ------- 
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the Trust Estate may  at the time be located, the Indenture
Trustee  shall have the  power and may,  with the  prior consent of  the Swap
Counterparty and  the Swap Guarantor  execute and deliver all  instruments to
appoint  one or  more  Persons to  act  as a  co-trustee  or co-trustees,  or
separate trustee or separate  trustees, of all or any part  of the Trust, and
to vest in such Person  or Persons, in such capacity  and for the benefit  of
the  Noteholders, the Swap Counterparty and the Swap Guarantor, such title to
the Trust Estate, or any part hereof, and, subject to the other provisions of
this  Section, such  powers, duties,  obligations, rights  and trusts  as the
Indenture  Trustee may  consider necessary  or desirable.   No  co-trustee or
separate trustee hereunder shall be required to meet the terms of eligibility
as a successor trustee under Section 6.11 and no notice to Noteholders of the
appointment of  any co-trustee  or separate trustee  shall be  required under
Section 6.08 hereof. 
 
     (b)  Every   separate  trustee  and  co-trustee  shall,  to  the  extent
permitted by law,  be appointed and  act subject to the  following provisions
and conditions: 
 
          (i)  all  rights,  powers,  duties  and  obligations  conferred  or
     imposed upon  the Indenture Trustee  shall be conferred or  imposed upon
     and exercised  or performed by  the Indenture Trustee and  such separate
     trustee  or co-trustee jointly  (it being understood  that such separate
     trustee or  co-trustee is not  authorized to act separately  without the
     Indenture Trustee joining in  such act), except to the extent that under
     any law of any  jurisdiction in which any particular act  or acts are to
     be performed  the Indenture Trustee shall be  incompetent or unqualified
     to perform such  act or acts, in which event such rights, powers, duties
     and obligations (including the  holding of title to the  Trust Estate or
     any portion  thereof in  any such jurisdiction)  shall be  exercised and
     performed singly by  such separate trustee or co-trustee,  but solely at
     the direction of the Indenture Trustee; 

        (ii)  no trustee hereunder  shall be personally liable  by reason of
     any act or omission of any other trustee hereunder; and 

       (iii)  the Indenture Trustee may  at any time accept the  resignation
     of or remove any separate trustee or co-trustee. 

    (c)  Any notice, request or other writing given to the Indenture Trustee
shall be deemed to have been given to each of the then separate trustees  and
co-trustees, as effectively  as if given to  each of them.   Every instrument
appointing any separate  trustee or co-trustee shall refer  to this Agreement
and the conditions of this Article VI.  Each separate trustee and co-trustee,
upon its acceptance of the trusts conferred, shall be vested with the estates
or property specified  in its instrument of appointment,  either jointly with
the  Indenture Trustee or separately, as may  be provided therein, subject to
all the provisions of this Indenture,  specifically including every provision
of this Indenture  relating to the conduct of, affecting the liability of, or
affording protection to, the Indenture  Trustee.  Every such instrument shall
be filed with the Indenture Trustee. 
 
     (d)  Any separate trustee  or co-trustee may at any  time constitute the
Indenture  Trustee,  its  agent  or  attorney-in-fact  with  full  power  and
authority, to the extent not prohibited by law, to do any lawful act under or
in respect of this Agreement on its behalf  and in its name.  If any separate
trustee  or co-trustee  shall die, become  incapable of acting,  resign or be
removed, all  of its estates,  properties, rights, remedies and  trusts shall
vest in and be exercised by the Indenture Trustee, to the extent permitted by
law, without the appointment of a new or successor trustee.  
 
      Section 6.11.  Eligibility; Disqualification.  The Indenture Trustee 
                     -----------------------------

authorized  to execute  and deliver  such document  in such  capacity on  its
behalf.

its fees and expenses, the Indenture Trustee  when required by the provisions

Certificates outstanding, all sums due the Indenture Trustee pursuant to this
Indenture have been paid, and all sums due the Swap Counterparty and the Swap
Guarantor have been paid,  release any remaining portion of the  Trust Estate
that  secured  the Notes  from the  lien  of this  Indenture.   The Indenture
Trustee shall release property  from the lien  of this Indenture pursuant  to
this Section 8.05 only upon receipt of an request from the Issuer accompanied
by an Officers'  Certificate, an  Opinion of  Counsel and a  letter from  the

enter into one or more indentures supplemental hereto in form satisfactory to
the Indenture Trustee, for any of the following purposes: 

         (i)  to correct or  amplify the description of any  property at any
     time subject to the lien of this Indenture, or better to  assure, convey
     and confirm unto the Indenture  Trustee any property subject or required
     to be subjected to the lien of this Indenture, or to subject to the lien
     of this Indenture additional property;

        (iv)  to cure any ambiguity, to  correct or supplement any provision
     herein or  in any supplemental  indenture that may be  inconsistent with
     any other provision  herein or in any supplemental  indenture or to make
     any other provisions with respect  to matters or questions arising under
     this Indenture or in any supplemental indenture; provided that such 
                                                      -------- 
    action shall not  adversely affect the interests of the Holders of the

          (v)  to evidence and provide for  the acceptance of the appointment
     hereunder by  a successor  trustee and to  add to  or change any  of the
     provisions of  this Indenture  as shall be  necessary to  facilitate the
     administration  of the  trusts  hereunder  by  more  than  one  trustee,
     pursuant to the requirements of Article VI; 

provided that no such indenture supplements shall be entered into unless the 
- -------- 
Indenture Trustee,  the Swap Counterparty  and the Swap Guarantor  shall have
received an  Opinion of  Counsel satisfactory to  the Swap  Counterparty, the
Swap Guarantor  and the Indenture  Trustee that entering into  such
indenture supplement  shall not  materially and  adversely affect  the interest
of any Noteholder or the  Swap Counterparty and shall not have  any material 
adverse tax  consequences to  the  Noteholders,  the Swap  Counterparty  or the
Swap Guarantor. 
 
     The Indenture Trustee is hereby  authorized to join in the  execution of
any  such  supplemental  indenture  and  to   make  any  further  appropriate
agreements and stipulations that may be therein contained. 
 
     (b)  The Issuer, the  Swap Counterparty and  the Indenture Trustee  may,
also without  the consent  of any of  the Holders of  the Notes but  with the
prior written consent  of the Swap Guarantor  and prior notice to  the Rating
Agencies, enter into  an indenture or indentures supplemental  hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any  of the provisions of, this  Indenture or of modifying  in any manner the
rights  of  the Holders  of  the Notes,  the  Swap Counterparty  or  the Swap
Guarantor under this Indenture; provided that such action shall not, as 
                                -------- 
evidenced by an Opinion of Counsel,  adversely affect in any material respect
the interests of any Noteholder, the Swap Counterparty or the Swap Guarantor.

                    --------------------------------------------------- 
Issuer, the Swap Counterparty and the Indenture Trustee, also may, with prior
confirmation  by  each Rating  Agency  that  such action  shall  not  cause a
withdrawal,  reduction or suspension of the  ratings assigned to the Notes or
the Certificates, and with the consent of the Swap Guarantor and  the Holders
of not less than a majority of the then Principal Amount of Notes, enter into
an indenture or indentures  supplemental hereto for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or of modifying in any manner the rights of the Holders of
the Notes or the Swap Counterparty under this Indenture; provided that,  
                                                         -------- 
without the consent  of the Holder of each Outstanding Note affected thereby,
no such supplemental indenture shall: 
 
          (i)  change the due date of payment of any installment of principal
     of or interest  on any Note, or reduce the principal amount thereof, the
     interest rate thereon,  or the redemption price with  respect thereto or
     change the provisions  of this Indenture relating to  the application of
     collections  on, or  the proceeds of  the sale  of, the Trust  Estate to
     payment of principal of or interest on the Notes, or change any place of
     payment  where,  or the  coin  or currency  in  which, any  Note  or the
     interest thereon is payable,  or impair the right to  institute suit for
     the  enforcement  of the  provisions  of  this  Indenture requiring  the
     application of funds  available therefor, as  provided in Article V,  to
     the  payment  of any  such  amount due  on  the Notes  on  or after  the

     affected thereby;  
 
         (vi)  modify any of the provisions  of this Indenture in such manner
     as to affect the calculation of the amount of any payment of interest or
     principal due on any Note on any  Payment  Date  (including  the  
     calculation of  any  of the  individual components of such calculation); 
     or 

       (vii)  permit the  creation of  any lien  ranking  prior to  or on  a
     parity with the lien of  this Indenture with respect to any  part of the
     Trust Estate  or, except as otherwise permitted  or contemplated herein,
     terminate the lien of this Indenture on any property at any time subject
     hereto or deprive the Holder of any Note of the security provided by the
     lien of this Indenture. 
 
     It shall not  be necessary  for Noteholders under  this Section 9.02  to
approve the  particular form of  any proposed supplemental indenture,  but it
shall be sufficient if such Noteholders shall approve the substance thereof. 

    Promptly after  the execution by  the Issuer, the Swap  Counterparty and
the Indenture Trustee of any  supplemental indenture pursuant to this Section
9.02, the Indenture Trustee shall mail  to the Holders of the Notes to  which
such amendment or  supplemental indenture relates  and the Swap  Counterparty
and the Swap  Guarantor a notice setting forth in general terms the substance
of such supplemental indenture.  Any failure of the Indenture Trustee to mail
such notice, or any defect therein, shall not, however, in  any way impair or
affect the validity of any such supplemental indenture. 

    Section 9.03.  Execution of Supplemental Indentures.  In executing, or 
                   ------------------------------------ 
ermitting  the  additional  trusts created  by,  any  supplemental indenture
permitted  by this  Article IX  or  the modification  thereby  of the  trusts
created  by  this Indenture,  the  Indenture  Trustee  shall be  entitled  to
receive, and subject to  Sections 6.01 and 6.02, shall be fully  protected in
relying  upon, an  Opinion  of Counsel  stating  that the  execution of  such
supplemental indenture  is authorized  or permitted by  this Indenture.   The
Indenture  Trustee may, but  shall not be  obligated to, enter  into any such 
supplemental  indenture  that  affects the  Indenture  Trustee's  own rights,
duties, liabilities or immunities under this Indenture or otherwise. 
 
     Section 9.04.  Effect of Supplemental Indenture.  Upon the execution of 
                    -------------------------------- 

any  supplemental indenture pursuant to the provisions hereof, this Indenture
shall  be  and shall  be  deemed to  be  modified and  amended  in accordance
therewith  with respect  to the  Notes affected  thereby, and  the respective
rights,  limitations   of  rights,   obligations,  duties,  liabilities   and
immunities under  this Indenture  of the Indenture  Trustee, the  Issuer, the
Swap Counterparty,  the Swap  Guarantor and  the Holders of  the Notes  shall
thereafter be  determined, exercised  and enforced  hereunder subject  in all
respects  to  such  modifications  and  amendments, and  all  the  terms  and
conditions of any  such supplemental indenture shall  be and be deemed  to be
part of the terms and conditions of this Indenture for any and all purposes.

                    --------------------------------------------- 
authenticated and delivered after the execution of any supplemental indenture
pursuant to  this Article IX may,  and if required  by the  Indenture Trustee
shall,  bear a notation in  form approved by the Indenture  Trustee as to any
matter provided for  in such supplemental  indenture.  If  the Issuer or  the
Indenture Trustee shall so determine, new Notes so modified as to conform, in
the opinion of the Indenture Trustee and the Issuer, to any such supplemental
indenture  may be prepared  and executed by the  Issuer and authenticated and
delivered by the Indenture Trustee in exchange for Outstanding Notes.

                                ------------- 
     Section 10.01. Form of Documents Delivered to Indenture Trustee; 
                    ------------------------------------------------- 
Delivery.  In any case where several matters are required to be certified by,
- -------- 
or  covered by an opinion of, any specified  Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may  certify or give an opinion with respect  to some matters and
one or more other such Persons  as to other matters, and any such  Person may
certify or give an opinion as to such matters in one or several documents. 
 
     Any certificate or opinion of an Authorized Officer of the Issuer may be
based, insofar as it relates to legal matters, upon a certificate  or opinion
of, or  representations by,  counsel, unless  such officer  knows, or  in the
exercise of reasonable care should  know, that the certificate or opinion  or
representations with  respect to  the matters upon  which his  certificate or
opinion  is based  are  erroneous.   Any  such certificate  of  an Authorized
Officer or Opinion of Counsel may be based, insofar as it  relates to factual
matters, upon a certificate or opinion  of, or representations by, an officer
or officers of the Issuer or the  Administrator, stating that the information
with respect to such  factual matters is in the  possession of the Issuer  or
the  Administrator,  unless  such  counsel  knows,  or  in  the  exercise  of
reasonable   care  should   know,  that   the  certificate   or   opinion  or
representations with respect to such matters are erroneous. 
 
     Where  any  Person is  required to  make,  give or  execute two  or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument. 
 
     Whenever  in  this Indenture,  in  connection  with  any application  or
certificate  or report  to  the Indenture  Trustee, it  is provided  that the
Issuer  shall deliver  any document as  a condition  of the granting  of such
application, or  as evidence of the Issuer's compliance with any term hereof,
it is intended that  the truth and accuracy,  at the time of the  granting of
such application or at the effective  date of such certificate or report  (as
the case  may be), of the facts and opinions stated in such document shall in
such case  be conditions precedent  to the right of  the Issuer to  have such
application granted or to the sufficiency of such certificate or report.  The
foregoing shall not, however, be  construed to affect the Indenture Trustee's
right  to  rely upon  the  truth and  accuracy  of any  statement  or opinion
contained in any such document as provided in Article VI. 
 
     Delivery of the Notes  hereunder by the  Indenture Trustee and the  Note
Registrar shall  be accomplished through  the Depository or at  the Corporate
Trust  Office  of  the  Indenture  Trustee  and/or  the  Note  Registrar,  as
applicable. 
 
     Section 10.02. Acts of Noteholders.  (a)  Any request, demand, 
                    ------------------- 
authorization, direction, notice, consent, waiver or other action provided by
this  Indenture to be  given or taken  by Noteholders may  be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Noteholders in person or by agents duly appointed in writing; and except
as herein  otherwise expressly  provided such  action shall  become effective
when such instrument  or instruments are delivered to  the Indenture Trustee,
and,  where  it  is hereby  expressly  required,  to the  Issuer.    Proof of
execution of any  such instrument or of  a writing appointing any  such agent
shall be  sufficient  for any  purpose  of  this Indenture  and  (subject  to
Section 6.01) conclusive in favor of the Indenture Trustee and the Issuer, if 
made in the manner provided in this Section 10.02. 
 
     (b)  The  fact and  date of  the  execution by  any Person  of  any such
instrument or  writing may be  proved by the affidavit  of a witness  of such
execution or by  a certificate of a notary public or other officer authorized
by  law to  take acknowledgements  of deeds,  certifying that  the individual
signing such instrument or writing acknowledged to him the execution thereof.
Where such  execution is  by a  signer acting in  a capacity  other than  his
individual  capacity, such  certificate or  affidavit  shall also  constitute
sufficient proof of his authority.  The fact and date of the execution of any
such  instrument or  writing, or  the authority of  the Person  executing the
same, may  also be  proved in any  other manner  which the  Indenture Trustee
deems sufficient. 
 
     (c)  The ownership of Notes shall be proved by the Note Register. 
 
     (d)  Any  request, demand,  authorization,  direction, notice,  consent,
waiver or other action  by the Holder of any  Notes shall bind the Holder  of

every Note issued upon the registration thereof or in exchange therefor or in

lieu thereof, in respect of anything done, omitted or  suffered to be done by

the Indenture  Trustee or  the  Issuer in  reliance thereon,  whether or  not

notation of such action is made upon such Note.

     Section 10.04. Notices to Noteholders; Waiver.  Where this Indenture 
                    ------------------------------ 
provides  for notice  to  Noteholders of  any  event,  such notice  shall  be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class, postage prepaid  to each Noteholder affected by such
event, at his address  as it appears on the Note Register, not later than the
latest  date, and  not earlier  than the  earliest date,  prescribed for  the
giving of  such notice.  In any case where  notice to Noteholders is given by
mail, neither the failure to mail such notice nor any defect in any notice so
mailed  to any  particular Noteholder  shall affect  the sufficiency  of such
notice with respect  to other Noteholders, and  any notice that is  mailed in
the manner herein  provided shall conclusively be presumed to  have been duly
given. 
 
     Where this Indenture provides for notice in any manner, such notice  may
be waived in  writing by any Person  entitled to receive such  notice, either
before or  after the event, and  such waiver shall be the  equivalent of such
notice.   Waivers of notice by Noteholders shall  be filed with the Indenture
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a waiver. 
 
     In case, by reason of the suspension of regular mail service as a result
of a strike,  work stoppage or similar  activity, it shall be  impractical to
mail notice  of any event to Noteholders  when such notice is  required to be
given pursuant to any provision of this  Indenture, then any manner of giving
such notice as shall be satisfactory to the Indenture Trustee shall be deemed
to be a sufficient giving of such notice. 
 
     Where this Indenture provides for notice to the Rating Agencies, failure
to give such notice shall not affect any other rights or  obligations created
hereunder,  and shall  not  under  any circumstance  constitute  an Event  of
Default. 
 
     Section 10.05. Alternate Payment and Notice Provisions.   
                    --------------------------------------- 
Notwithstanding any provision of this Indenture or any of the Notes  
on the contrary, the Issuer may enter into any agreement with any Holder of a
Note providing for a method of payment, or notice by the Indenture Trustee or
the Administrator to such Holder, that is different from the methods provided
for in this Indenture for such payments or notices.  The Issuer shall furnish
to the  Indenture Trustee  a copy of  each such  agreement and  the Indenture
Trustee shall cause payments to be made and notices to be given in accordance
with such agreements. 
 
     Section 10.06. Effect of Headings.  The Article and Section headings

The parties hereby expressly agree that the Issuer and the  Swap Counterparty
may assign their respective rights hereunder and Swap Agreement in connection 
with a Replacment Event under and as provided herein and the Basic Documents.

     Section 10.08. Separability.  In case any provision in this Indenture 
                    ------------ 
or  in the Notes  shall be invalid,  illegal or unenforceable,  the validity,
legality, and enforceability of the remaining provisions shall not in any way
be affected or impaired thereby. 
 
     Section 10.09. Benefits of Indenture.  Nothing in this Indenture or in 
                    --------------------- 
the Notes,  express or  implied, shall  give to  any Person,  other than  the
parties hereto and their successors  hereunder, and the Noteholders, the Swap
Guarantor, and any  other party secured hereunder, and any  other Person with
an ownership interest  in any part of  the Trust Estate,  any benefit or  any
legal or equitable right, remedy or claim under this Indenture. 
 
     Section 10.10. Legal Holidays.  In any case where the date on which any 
                    -------------- 
payment is due shall  not be a Business Day, then  (notwithstanding any other
provision of the Notes or  this Indenture) payment need  not be made on  such
date, but may be made on the next succeeding Business Day with the same force
and effect  as if made on  the date on  which nominally due, and  no interest
shall accrue for the period from and after any such nominal date. 
 
     Section 10.11. GOVERNING LAW.  THIS INDENTURE SHALL BE CONSTRUED IN 
                    ------------- 
ACCORDANCE WITH  THE LAWS  OF THE  STATE OF  NEW YORK,  AND THE  OBLIGATIONS,
RIGHTS  AND  REMEDIES  OF  THE  PARTIES  HEREUNDER  SHALL  BE  DETERMINED  IN
ACCORDANCE WITH SUCH LAWS. 
 
     Section 10.12. Counterparts.  This Indenture may be executed in any 
                    ------------ 
number of counterparts, each of  which so executed shall  be deemed to be  an
original, but all such counterparts shall together constitute but one and the
same instrument. 
 
     Section 10.13. Recording of Indenture.  If this Indenture is subject to 
                    ---------------------- 
recording in any  appropriate public recording offices, such  recording is to
be effected by  the Issuer and at  its expense accompanied  by an Opinion  of
Counsel (which may be counsel to the Indenture Trustee, the Swap Counterparty
or the Swap Guarantor) to the effect that such recording is  necessary either
for the protection  of the Noteholders,  the Swap Counterparty  or any  other
Person  secured hereunder  or  for the  enforcement  of any  right  or remedy
granted to the Indenture Trustee under this Indenture. 
 
     Section 10.14. Trust Obligation.  No recourse may be taken, directly or 
                    ---------------- 
indirectly, with respect to the obligations of the Issuer, the Owner Trustee,
the  Indenture Trustee,  the Swap Counterparty  or the Swap  Guarantor on the
Notes  or under this Indenture or any  certificate or other writing delivered
in connection herewith or therewith, against (i) the Indenture Trustee or the
Owner  Trustee in  its individual  capacity, (ii) any  owner of  a beneficial
interest in  the  Issuer or  (iii) any  partner, owner,  beneficiary,  agent,

Trustee  in its  individual capacity  ,  the Swap  Counterparty  or the  Swap
Guarantor, or any  holder of a beneficial  interest in the Issuer,  the Owner
Trustee, the Indenture Trustee, the  Swap Counterparty or the Swap Guarantor,

shall  be fully  liable, to the  extent provided  by applicable law,  for any
unpaid consideration for stock, unpaid capital contribution or failure to pay
any installment or  call owing  to such  entity.   For all  purposes of  this
Indenture,  in the  performance of any  duties or  obligations of  the Issuer
hereunder, the  Owner  Trustee  shall be  subject  to, and  entitled  to 
the benefits of, the  terms and  provisions of  Article VI, VII and  VIII 
of  the Trust Agreement. 
 
     Section 10.15. No Petition.  The Indenture Trustee and the Swap 
                    ----------- 
Counterparty,  by  entering into  this  Indenture,  and each  Noteholder,  by
accepting a Note, hereby covenant and  agree that they shall not at  any time
institute against  the Depositor or  the Issuer,  or join in  any institution
against the  Depositor  or the  Issuer  of, any  bankruptcy,  reorganization,
arrangement,  insolvency or  liquidation  proceedings,  or other  proceedings
under any  United  States  federal or  state  bankruptcy or  similar  law  in
connection with any  obligations relating to the Notes, this Indenture or any

     Mortgage Index Amortizing Trust 1997-1,  a business trust duly organized
and existing under the laws  of the State of Delaware (herein  referred to as
the "Issuer"), for value  received, hereby promises to pay  to Cede & Co.  or
registered assigns, in accordance with the terms of an Indenture, dated as of
September 1,  1997 as  supplemented or  amended, among  the Issuer,  the Swap
Counterparty and The  Bank of New York, as  indenture trustee (the "Indenture
Trustee,"  which term  includes  any successor  Indenture  Trustee under  the
Indenture),  the  principal sum  of_______________________________   or  such
lesser amount payable  pursuant to the Indenture, and interest  on the unpaid
amount  hereof in the  manner hereinafter described until  this Note has been
paid in full. 
 
     The Issuer will  pay interest on this Note as described in the Indenture
on each Payment  Date until the  principal of  this Note (as  may be  reduced
pursuant  to  the terms  of  the Indenture)  is  paid or  made  available for
payment, on the  outstanding principal amount of this Note (as may be reduced
pursuant to the terms of the Indenture) during the preceding Interest Accrual
Period (as  defined below), subject  to certain limitations contained  in the
Indenture.  Interest on this Note will accrue from the Closing Date at a rate
per  annum  equal to  ____%,  calculated  on  the  basis of  a  360-day  year
consisting of twelve 30-days months  (the "Note Accrual Rate").  Interest  in
respect of  a Payment Date will  accrue on this  Note from and  including the
preceding Payment Date (or in  the case of the  first Payment Date, from  and
including the Closing  Date) to but excluding such current Payment Date (each
an "Interest Accrual  Period") and will be payable to  Noteholders monthly in
arrears  on each  Payment Date.   "Payment Date"  means the 25th  day of each
month  or, if such day  is not a  Business Day, the  next succeeding Business
Day.  A failure to pay  interest due on the Notes on any  Payment Date, which
failure continues for five Business Days, constitutes an Event of Default (as
defined herein) under the Indenture. 
 
     Principal of this Note (as  may be reduced pursuant to the terms  of the
Indenture) will be  payable as  described on  the reverse hereof  and in  the
Indenture. 
 
     The principal of and interest on  this Note are payable in such  coin or
currency of the United States  of America as at the time of  payment is legal
tender for  payment of public  and private debts.   All payments made  by the
Issuer  with respect to this Note shall be  applied first to interest due and
payable on this  Note as provided above  and then to the unpaid  principal of
this Note. 
 
     Reference is made  to the further provisions  of this Note set  forth on
the reverse  hereof, which  shall have the  same effect  as though  fully set
forth on the face of this Note. 

    The terms of this Note shall be governed by the Indenture and in case of
any inconsistency between the  terms set forth herein and those  set forth in
the Indenture, those provisions of the Indenture shall govern. 

    Unless the certificate of authentication hereon has been executed by the
Indenture Trustee  whose name  appears below by  manual signature,  this Note
shall not be entitled to any  benefit under the Indenture referred to on  the
reverse hereof, or be valid or obligatory for any purpose.  
 
      IN WITNESS  WHEREOF, the Issuer  has caused this  instrument to be 
duly executed, as of the date set forth below.

                                   individual   capacity   but    solely   as
                                   Indenture Trustee,

                              (Reverse of Note) 
 
 
     This  Note is one  of a  duly authorized issue  of Notes  of the Issuer,
designated as its  Fixed Rate Asset Backed Notes, Class A1 (herein called the
"Notes"),  all  issued  under  the  Indenture, to  which  Indenture  and  all
indentures supplemental thereto  reference is hereby made for  a statement of
the respective rights and obligations thereunder of the Issuer, the Indenture
Trustee,  the Swap  Counterparty, the Swap  Guarantor and the  Holders of the
Notes.  The Notes are subject to all terms of the Indenture. 

    The Notes are and will be equally and ratably secured by  the Collateral
(as defined in the Indenture) pledged as security therefor as provided in the
Indenture.   The  Notes are  payable solely from  proceeds of  the Collateral
owned by  the Issuer in accordance with the  Priority of Payments (as defined
in the Indenture). 
 
     The  Notes are  subject to  prepayment  as described  in the  Indenture.
Principal of the Notes  is expected to be prepaid beginning  on the September
1999 Payment Date, as described in the Indenture.   

    The entire unpaid principal amount of this Note shall be due and payable
on the Final Scheduled Payment Date pursuant to the Indenture, or the date of
any Mandatory Prepayment  as provided in the Indenture.   Notwithstanding the
foregoing, the entire unpaid  principal amount of the Notes shall  be due and
payable on the date on which  an Event of Default shall have occurred  and be
continuing and  the Indenture  Trustee shall  have declared  the Notes  to be
immediately due and  payable in the  manner provided in  the Indenture.   All
principal payments  on the Notes  shall be made  pro rata to  the Noteholders
entitled thereto. 

    Payments of interest  on this Note due and payable on each Payment Date,
together with the installment of principal, if any, to the extent not in full
payment of this Note, shall be made by  wire transfer to an account specified
in writing by the Holder and reasonably satisfactory to the Indenture Trustee
or by check mailed to the Person whose name appears as the Registered Holder  
of this Note  (or one or more  predecessor Notes) on the Note  Register as of
the close of business on each Record Date, except that  with respect to Notes
registered on  the Record Date in  the name of the nominee  of the Depository
(initially, such  nominee to be  Cede & Co.), payments  will be made  by wire
transfer  in immediately  available funds  to the  account designated  by the
Depository  or such  nominee.   Such  checks shall  be mailed  to  the Person
entitled  thereto at the  address of  such Person as  it appears on  the Note
Register as of the applicable Record Date without requiring that this Note be
submitted for notation of payment.  Any reduction in the principal  amount of
this Note (or  any one or  more predecessor Notes)  effected by any  payments
made on any  Payment Date, or by the application of Credit Losses (as defined
in the Indenture) thereto as provided in the Indenture, shall be binding upon
all future Holders of this Note and of any Note issued upon the  registration
of  transfer hereof or in  exchange hereof or in  lieu hereof, whether or not
noted hereon.   The Indenture Trustee,  in the name  of and on behalf  of the
Issuer, will notify the Person who was the Registered Holder hereof as of the
Record Date  preceding the Final Scheduled  Payment Date by  notice mailed or
transmitted by facsimile prior to such Payment Date, and the amount  then due
and payable  shall be payable  only upon  presentation and surrender  of this
Note at the Indenture Trustee's principal Corporate Trust Office or as may be
otherwise provided in the Indenture. 

     The Issuer  shall pay interest  on overdue installments of  interest and
principal at the Note Accrual Rate to the extent lawful. 
 
     Each Noteholder or  Note Owner, by acceptance of a Note  or, in the case
of a  Note Owner, a beneficial interest in  a Note, covenants and agrees that
no  recourse may  be  taken,  directly or  indirectly,  with respect  to  the
obligations of the Issuer, the Owner Trustee, the Indenture Trustee, the Swap
Counterparty or the Swap Guarantor on the Notes or under the Indenture or any
certificate  or  other  writing delivered  in  connection  therewith, against
(i) the Indenture  Trustee or the  Owner Trustee in its  individual capacity,
(ii) any owner of a  beneficial interest in the Issuer  or (iii) any partner,
owner, beneficiary, agent,  officer, director  or employee  of the  Indenture
Trustee, the Owner Trustee in  its individual capacity, the Swap Counterparty
or the Swap Guarantor, or any holder of a beneficial interest  in the Issuer,
the  Owner Trustee, the Indenture Trustee,  the Swap Counterparty or the Swap
Guarantor, except  as any  such Person may  have expressly  agreed (it  being
understood that  the Indenture  Trustee and  the Owner Trustee  have no  such
obligations in their  individual capacity) and except that  any such partner,
owner  or beneficiary  shall  be  fully liable,  to  the  extent provided  by
applicable  law,  for any  unpaid  consideration  for stock,  unpaid  capital
contribution or failure to pay any installment or call owing to such entity. 
 
      Each Noteholder or Note  Owner, by acceptance of a Note or, in the case
of  a Note Owner,  a beneficial interest  in a Note, covenants  and agrees by
accepting the benefits of this Note and the Indenture that such Noteholder or
Note  Owner will  not at  any  time institute  against the  Depositor  or the
Issuer, or join  in any institution against  the Depositor or the  Issuer of,
any  bankruptcy,  reorganization,  arrangement,  insolvency  or   liquidation
proceedings under  any United States  federal or state bankruptcy  or similar
law in connection  with any obligations relating to the  Notes, the Indenture
or the other Basic Documents. 
 
     The Issuer has entered  into the Indenture and this Note  is issued with
the intention that,  for federal, state and local income, single business and
franchise tax purposes, the Notes will qualify as indebtedness secured by the
Trust Estate (as defined  in the Indenture).  Each Noteholder,  by acceptance
of a Note (and each  Note Owner by acceptance of  a beneficial interest in  a
Note), agrees to treat the Notes for federal, state and local  income, single
business and franchise tax purposes as indebtedness. 

    Prior to the due presentment for  registration of transfer of this Note,
the  Issuer,  the  Indenture Trustee  and  any  agent of  the  Issuer  or the
Indenture Trustee may treat the Person in whose name this Note (as of the day
of  determination or  as  of such  other  date as  may  be specified  in 
the Indenture) is registered as the owner hereof for all purposes, whether or 
not this  Note be overdue, and none  of the Issuer, the  Indenture Trustee or 
any such agent shall be affected by notice to the contrary. 
 
     Subject  to certain terms,  conditions and exceptions  therein provided,
the  Indenture permits  the amendment  thereof  and the  modification of  the
rights  and obligations of  the Issuer and  the rights of the  Holders of the
Notes under the Indenture as provided  in the Indenture.  The Indenture  also
contains  provisions permitting the  Holders of Notes  representing specified
percentages of the Principal Amount of the Notes, on behalf of the Holders of
