P8 =      P2 + P4.

DIFF_Y8 =      DIFF_Y2 + DIFF_Y4.- kDeltaY4


1.   If Y9 - alpha(P9 - DeltaP9)  0, Y8- alpha(P8 - DeltaP8)
  0, and gamma1(P8 - DeltaP8) < (P9 - DeltaP9), DeltaY9 = Y9 -
   alphagamma1(P8 - DeltaP8) and DeltaY8 = Y8 - alpha(P8 -

2.   If Y9 - alpha(P9 - DeltaP9)  0,
  Y8 - alpha(P8 - DeltaP8)  0, and gamma1(P8 - DeltaP8)
  (P9 - DeltaP9), DeltaY9 = Y9 - alpha(P9 - DeltaP9) and
  DeltaY8 = Y8 - (alpha/gamma1)(P9 - DeltaP9).

3.   If Y9 - alpha(P9 - DeltaP9) < 0,
  Y8 - alpha(P8 - DeltaP8)  0, and Y8 - alpha(P8 - DeltaP8)
  Y8 - (Y9/gamma1), DeltaY9 = Y9 - alphagamma1(P8 - DeltaP8)
  and DeltaY8 = Y8 - alpha(P8 - DeltaP8).
4.   If Y9 - alpha(P9 - DeltaP9) < 0, Y8 - (Y9/gamma1)  0,
and Y8 - alpha(P8 - DeltaP8)  Y8 - (Y9/gamma1), DeltaY9 = 0
and DeltaY8 = Y8 - (Y9/gamma1).
5.   If Y8 - alpha(P8 - DeltaP8) < 0, Y8 - (Y9/gamma1) < 0,
and Y9 - alpha(P9 - DeltaP9)  Y9 - (gamma1Y8),

The purpose of the foregoing definitional provisions
together with the related provisions allocating Realized
Losses and defining the Class Y and Class Z Principal
Distribution Amounts is to accomplish the following goals in
the following order of priority:
     
  1.   Making the ratio of Y9 to Y8 equal to gamma1 after
     taking account of the allocation Realized Losses and the
     distributions that will be made through end of the
<PAGE>



<PAGE> 38

     Distribution Date to which such provisions relate and
     assuring that the Principal Reduction Amount for each of the
     Class Y-1, Class Y-2, Class Y-3, Class Y-4, Class Z-1 Class
     Z-2, Class Z-3 and Class Z-4 Regular Interests is greater
     than or equal to zero for such Distribution Date;
  2.   Making the Class Y-1 Principal Balance less than or
     equal to 0.0005 of the sum of the Class Y-1 and Class Z-1
     Principal Balances, the Class Y-2 Principal Balance less
     than or equal to 0.0005 of the sum of the Class Y-2 and
     Class Z-2 Principal Balances, the Class Y-3 Principal
     Balance less than or equal to 0.0005 of the sum of the Class
     Y-3 and Class Z-3 Principal Balances and the Class Y-4
     Principal Balance less than or equal to 0.0005 of the sum of
     the Class Y-4 and Class Z-4 Principal Balances in each case
     after giving effect to allocations of Realized Losses and
     distributions to be made through the end of the Distribution
     Date to which such provisions relate; and
  3.   Making the larger of (a) the fraction whose numerator
     is Y9 and whose denominator is the sum of Y9, the Class Z-1
     Principal Balance and the Class Z-3 Principal Balance and
     (b) the fraction whose numerator is Y8 and whose denominator
     is the sum of Y8, the Class Z-2 Principal Balance and the
     Class Z-4 Principal Balance as large as possible while
     remaining less than or equal to 0.0005.

In the event of a failure of the foregoing portion of the
definition of Class Y Principal Reduction Amount to
accomplish both of goals 1 and 2 above, the amounts thereof
should be adjusted to so as to accomplish such goals within
the requirement that each Class Y Principal Reduction Amount
must be less than or equal to the sum of (a) the principal
portion of Realized Losses to be allocated on the related
Distribution Date for the related Loan Group remaining after
the allocation of such Realized Losses to the related Class
P-M Regular Interests and (b) the remainder of the REMIC I
Available Distribution Amount for the related Loan Group or
after reduction thereof by the distributions to be made on
such Distribution Date (i) to the related Class P-M Regular
Interests, (ii) to the related Class X-M Regular Interests
and (iii) in respect of interest on the related Class Y and
Class Z Regular Interests, or, if both of such goals cannot
be accomplished within such requirement, such adjustment as
is necessary shall be made to accomplish goal 1 within such
requirement.  In the event of any conflict among the
provisions of the definition of the Class Y Principal
Reduction Amounts, such conflict shall be resolved on the
basis of the goals and their priorities set forth above
within the requirement set forth in the preceding sentence.
If the formula allocation of DIFF_Y8 between DIFF_Y2 and
DIFF_Y4 cannot be achieved because either DIFF_Y2 as so
defined is greater than DIFF_P2 or DIFF_Y4 as so defined is
greater than DIFF_P4, such an allocation shall be made as
<PAGE>



<PAGE> 39

close as possible to the formula allocation within the
requirement that DIFF_Y2 < DIFF_P2 and DIFF_Y4 < DIFF_P4.

II.  If R6.5% and r1<R1, make the following additional
     definitions:

kDeltaY2 =     Y2 + ((R1 - 6.5%)/(R1 - 6.0%))Y4

kDeltaY2 is a number between Y2 and 0 such that (6.0%(Y2 -
     kDeltaY2)  + 6.5%Y4)/(Y2 - kDeltaY2 + Y4.) = R1.

Y5 =      Y2 - kDeltaY2 + Y4.

P5 =      P2 + P4.

DIFF_Y5 =      DIFF_Y2 - kDeltaY2 + DIFF_Y4.


1.   If Y9 - alpha(P9 - DeltaP9)  0, Y5- alpha(P5 - DeltaP5)
  0, and gamma1(P5 - DeltaP5) < (P9 - DeltaP9), DeltaY9 = Y9 -
   alphagamma1(P5 - DeltaP5) and DeltaY5 = Y5 - alpha(P5 -
   DeltaP5).

2.   If Y9 - alpha(P9 - DeltaP9)  0,
  Y5 - alpha(P5 - DeltaP5)  0, and gamma1(P5 - DeltaP5)
  (P9 - DeltaP9), DeltaY9 = Y9 - alpha(P9 - DeltaP9) and

together with the related provisions allocating Realized
Losses and defining the Class Y and Class Z Principal
Distribution Amounts is to accomplish the following goals in
the following order of priority:
     
  1.   Making the ratio of Y9 to Y5 equal to gamma1 after
     taking account of the allocation Realized Losses and the
     distributions that will be made through end of the
     Distribution Date to which such provisions relate and
     assuring that the Principal Reduction Amount for each of the
     Class Y-1, Class Y-2, Class Y-3, Class Y-4, Class Z-1, Class
     Z-2, Class Z-3 and Class Z-4 Regular Interests is greater
     than or equal to zero for such Distribution Date;
  2.   Making the Class Y-1 Principal Balance less than or
     equal to 0.0005 of the sum of the Class Y-1 and Class Z-1
     Principal Balances, the Class Y-2 Principal Balance less
     than or equal to 0.0005 of the sum of the Class Y-2 and

     after giving effect to allocations of Realized Losses and
     distributions to be made through the end of the Distribution
     Date to which such provisions relate; and
  3.   Making the larger of (a) the fraction whose numerator
     is Y9 and whose denominator is the sum of Y9, the Class Z-1
     Principal Balance and the Class Z-3 Principal Balance and

     is the sum of Y5, the Class Z-2 Principal Balance and the
     Class Z-4 Principal Balance as large as possible while
     remaining less than or equal to 0.0005.

In the event of a failure of the foregoing portion of the
definition of Class Y Principal Reduction Amount to
accomplish both of goals 1 and 2 above, the amounts thereof
should be adjusted to so as to accomplish such goals within
the requirement that each Class Y Principal Reduction Amount
must be less than or equal to the sum of (a) the principal
portion of Realized Losses to be allocated on the related
Distribution Date for the related Loan Group remaining after
the allocation of such Realized Losses to the related Class

Class Z Regular Interests, or, if both of such goals cannot
be accomplished within such requirement, such adjustment as
is necessary shall be made to accomplish goal 1 within such
requirement.  In the event of any conflict among the

  Y2 - alpha(P2 - DeltaP2)  0, and Y2 - alpha(P2 - DeltaP2)
  Y2 - (Y6/gamma2), DeltaY6 = Y6 - alphagamma2(P2 - DeltaP2)
  and DeltaY2 = Y2 - alpha(P2 - DeltaP2).

4.   If Y6 - alpha(P6 - DeltaP6) < 0, Y2 - (Y6/gamma2)  0,
  and Y2 - alpha(P2 - DeltaP2)  Y2 - (Y6/gamma2), DeltaY6 = 0
  and DeltaY2 = Y2 - (Y6/gamma2).

5.   If Y2 - alpha(P2 - DeltaP2) < 0, Y2 - (Y6/gamma2) < 0,

Distribution Amounts is to accomplish the following goals in
the following order of priority:
     
  1.Making the ratio of Y1 to Y6 equal to gamma2 after
     taking account of the allocation Realized Losses and
     the distributions that will be made through end of the

be accomplished within such requirement, such adjustment as
is necessary shall be made to accomplish goal 1 within such
requirement.  In the event of any conflict among the
provisions of the definition of the Class Y Principal

If the formula allocation of DIFF_Y6 between DIFF_Y9 and
DIFF_Y4 cannot be achieved because either DIFF_Y9 as so

greater than DIFF_P4, such an allocation shall be made as
close as possible to the formula allocation within the
requirement that DIFF_Y9 < DIFF_P9 and DIFF_Y4 < DIFF_P4.

IV.  If R<6.5% and r2<R2, make the following additional
     definitions:

       Designations; Original Issuance of Certificates
                              
     Section 2.01.  Conveyance of the Trust Fund; REMIC Election
and Designations.  The Trust of which the Trustee is the
trustee is hereby created under the laws of the State of New
York for the benefit of the Holders of the REMIC I Regular
Interests and the Class R-1 Certificates.  The purpose of
the Trust is to hold the Trust Fund and provide for the
issuance, execution and delivery of the Class R-1
Certificates.  The assets of the Trust shall consist of the
Trust Fund.  The Trust shall be irrevocable.

     The assets of the Trust shall remain in the custody of
<PAGE>



<PAGE> 138

the Trustee, on behalf of the Trust, and shall be kept in
the Trust.  Moneys to the credit of the Trust shall be held
by the Trustee and invested as provided herein.  All assets
received and held in the Trust will not be subject to any
right, charge, security interest, lien or claim of any kind
in favor of State Street Bank and Trust Company in its own
right, or any Person claiming through it.  The Trustee, on
behalf of the Trust, shall not have the power or authority
to transfer, assign, hypothecate, pledge or otherwise
dispose of any of the assets of the Trust to any Person,
except as permitted herein.  No creditor of a beneficiary of
the Trust, of the Trustee, of the Master Servicer or of the
Company shall have any right to obtain possession of, or
otherwise exercise legal or equitable remedies with respect
to, the property of the Trust, except in accordance with the
terms of this Agreement.

     Concurrently with the execution and delivery hereof,
the Company does hereby irrevocably sell, transfer, assign,
set over and otherwise convey to the Trustee, in trust for
the benefit of the Holders of REMIC I Regular Interests and
the Class R-1 Certificates, without recourse, all the
Company's right, title and interest in and to the Trust
Fund, including but not limited to (i) all scheduled
payments of principal and interest due after the Cut-Off
Date and received by the Company with respect to the
Mortgage Loans at any time, and all Principal Prepayments
received by the Company after the Cut-Off Date with respect
to the Mortgage Loans (such transfer and assignment by the
Company to be referred to herein as the "Conveyance"). The
Trustee hereby accepts the Trust created hereby and accepts
delivery of the Trust Fund on behalf of the Trust and
acknowledges that it holds the Mortgage Loans for the
benefit of the Holders of the REMIC I Regular Interests and
the Class R-1 Certificates issued pursuant to this
Agreement. It is the express intent of the parties hereto
that the Conveyance of the Trust Fund to the Trustee by the
Company as provided in this Section 2.01 be, and be
construed as, an absolute sale of the Trust Fund. It is,
further, not the intention of the parties that such
Conveyance be deemed a pledge of the Trust Fund by the
Company to the Trustee to secure a debt or other obligation
of the Company. However, in the event that, notwithstanding
the intent of the parties, the Trust Fund is held to be the
property of the Company, or if for any other reason this
Agreement is held or deemed to create a security interest in
the Trust Fund, then

     (a)  this Agreement shall be deemed to be a security
agreement;

     (b)  the Conveyance provided for in this Section 2.01
<PAGE>



<PAGE> 139

shall be deemed to be a grant by the Company to the Trustee
of a security interest in all of the Company's right, title,
and interest, whether now owned or hereafter acquired, in
and to:

     (I) All accounts, general intangibles, chattel paper,
instruments, documents, money, deposit accounts,
certificates of deposit, goods, letters of credit, advices
of credit and investment property consisting of, arising
from or relating to any of the property described in (i),
(ii) and (iii) below: (i) the Mortgage Loans identified on
the Mortgage Loan Schedule, including the related Mortgage
Notes, Mortgages, Cooperative Stock Certificates, and
Cooperative Leases, all Substitute Mortgage Loans and all
distributions with respect to such Mortgage Loans and
Substitute Mortgage Loans payable on and after the Cut-Off
Date; (ii) the Certificate Account, the Investment Account,
the Class I-A-14 Rounding Account, and all money or other
property held therein, and the Custodial Accounts for P&I
and the Custodial Accounts for Reserves (to the extent of
the amounts on deposit or other property therein
attributable to the Mortgage Loans); and (iii) the
Certificate Insurance Policy, the CMAC Policy and amounts
paid or payable by the insurer under any FHA insurance
policy or any Primary Insurance Policy and proceeds of any
VA guaranty and any other insurance policy related to any
Mortgage Loan or the  Mortgage Pool;

     (II) All accounts, general intangibles, chattel paper,
instruments, documents, money, deposit accounts,
certificates of deposit, goods, letters of credit, advices
of credit, investment property, and other rights arising
from or by virtue of the disposition of, or collections with
respect to, or insurance proceeds payable with respect to,
or claims against other persons with respect to, all or any
part of the collateral described in (I) above (including any
accrued discount realized on liquidation of any investment
purchased at a discount); and

     (III) All cash and non-cash proceeds of the collateral
described in (I) and (II) above;

     (c)  the possession by the Trustee of the Mortgage
Notes, the Mortgages, the Security Agreements, Assignments
of Proprietary Lease, Cooperative Stock Certificates,
Cooperative Leases and such other goods, letters of credit,
advices of credit, instruments, money, documents, chattel
paper or certificated securities shall be deemed to be
possession by the secured party or possession by a purchaser
for purposes of perfecting the security interest pursuant to
the Uniform Commercial Code (including, without limitation,
Sections 9-305 and 9-115 thereof) as in force in the
<PAGE>



<PAGE> 140

relevant jurisdiction; and

     (d)  notifications to persons holding such property,
and acknowledgments, receipts or confirmations from persons
holding such property, shall be deemed to be notifications
to, or acknowledgments, receipts or confirmations from,
securities intermediaries, bailees or agents of, or persons
holding for, the Trustee, as applicable for the purpose of
perfecting such security interest under applicable law.

     The Company and the Trustee at the direction of the
Company shall, to the extent consistent with this Agreement,
take such actions as may be necessary to ensure that, if
this Agreement were deemed to create a security interest in
the Trust Fund, such security interest would be deemed to be
a perfected security interest of first priority under
applicable law and will be maintained as such throughout the
term of the Agreement. In connection herewith, the Trustee
shall have all of the rights and remedies of a secured party
and creditor under the Uniform Commercial Code as in force
in the relevant jurisdiction.

     In connection with the sale, transfer and assignment
referred to in the first paragraph of this Section 2.01, the
Company, concurrently with the execution and delivery
hereof, does deliver to, and deposit with, or cause to be
delivered to and deposited with, the Trustee or Custodian
the Mortgage Files for the Mortgage Loans, which shall on
original issuance thereof and at all times be registered in
the name of the Trustee.

     Concurrently with the execution and delivery hereof,
the Company shall cause assignments of the Mortgage Loans to
the Trustee to be recorded or filed, except in states where,
in the opinion of counsel admitted to practice in such state
acceptable to the Company, the Trustee and the Rating
Agencies submitted in lieu of such recording or filing, such
recording or filing is not required to protect the Trustee's
interest in such Mortgage Loans against creditors of, or
against sale, further assignments, satisfaction or discharge
by the Lender, a Servicer, the Company or the Master
Servicer, and the Company shall cause to be filed the Form
UCC-3 assignment and Form UCC-1 financing statement referred
to in clause (Y)(vii) and (ix), respectively, of the
definition of "Mortgage File." In connection with its
servicing of Cooperative Loans, the Master Servicer will use
its best efforts to file timely continuation statements, if
necessary, with regard to each financing statement and
assignment relating to Cooperative Loans.

     In instances where the original recorded Mortgage or
any intervening assignment thereof (recorded or in
<PAGE>



<PAGE> 141

recordable form) relating to a Mortgage Loan cannot be
delivered by the Company to the Trustee prior to or
concurrently with the execution and delivery hereof (due to
a delay on the part of the recording office), the Company
may, in lieu of delivering such original documents, deliver
to the Trustee a fully legible reproduction of the original
Mortgage or intervening assignment provided that the related
Lender or originator certifies on the face of such
reproduction(s) or copy as follows: "Certified true and
correct copy of original which has been transmitted for
recordation." For purposes hereof, transmitted for
recordation means having been mailed or otherwise delivered
for recordation to the appropriate authority. In all such
instances, the Company shall transmit the original recorded
Mortgage and any intervening assignments with evidence of
recording thereon (or a copy of such original Mortgage or
intervening assignment certified by the applicable recording
office)(collectively, "Recording Documents") to the Trustee
within 270 days after the execution and delivery hereof. In
instances where, due to a delay on the part of the recording
office where any such Recording Documents have been
delivered for recordation, the Recording Documents cannot be
delivered to the Trustee within 270 days after execution and
delivery hereof, the Company shall deliver to the Trustee
within such time period a certificate (a "Company Officer's
Certificate") signed by the Chairman of the Board,
President, any Vice President or Treasurer of the Company
stating the date by which the Company expects to receive
such Recording Documents from the applicable recording
office. In the event that Recording Documents have still not
been received by the Company and delivered to the Trustee by
the date specified in its previous Company Officer's
Certificate delivered to the Trustee, the Company shall
deliver to the Trustee by such date an additional Company
Officer's Certificate stating a revised date by which the
Company expects to receive the applicable Recording
Documents. This procedure shall be repeated until the
Recording Documents have been received by the Company and
delivered to the Trustee.

     In instances where, due to a delay on the part of the
title insurer, a copy of the title insurance policy for a
particular Mortgage Loan cannot be delivered to the Trustee
prior to or concurrently with the execution and delivery
hereof, the Company shall provide a copy of such title
insurance policy to the Trustee within 90 days after the
Company's receipt of the Recording Documents necessary to
issue such title insurance policy. In addition, the Company
shall, subject to the limitations set forth in the preceding
sentence, provide to the Trustee upon request therefor a
duplicate title insurance policy for any Mortgage Loan.

<PAGE>



<PAGE> 142

     For Mortgage Loans for which the Company has received a
Payoff after the Cut-Off Date and prior to the date of
execution and delivery hereof, the Company, in lieu of
delivering the above documents, herewith delivers to the
Trustee a certification of a Servicing Officer of the nature
set forth in Section 3.10.

     The Trustee is authorized, with the Master Servicer's
consent, to appoint any bank or trust company approved by
and unaffiliated with each of the Company and the Master
Servicer as Custodian of the documents or instruments
referred to above in this Section 2.01, and to enter into a
Custodial Agreement for such purpose, provided, however,
that the Trustee shall be and remain liable for the acts of
any such Custodian only to the extent that it is responsible
for its own acts hereunder.

     The Company and the Trustee agree that the Company, as
agent for the Tax Matters Person, shall, on behalf of the
REMIC I Trust Fund, elect to treat the REMIC I Trust Fund as
a REMIC within the meaning of Section 860D of the Code and,
if necessary, under applicable state laws. Such election
shall be included in the Form 1066 and any appropriate state
return to be filed on behalf of REMIC I for its first
taxable year.

     The Closing Date is hereby designated as the "startup
day" of REMIC I within the meaning of Section 860G(a)(9) of
the Code.

     The regular interests (as set forth in the table
contained in the Preliminary Statement hereto) relating to
the REMIC I Trust Fund are hereby designated as "regular
interests" for purposes of Section 860G(a)(1) of the Code.
The Class R-1 Certificates are being issued in a single
Class, which is hereby designated as the sole class of
"residual interest" in the REMIC I Trust Fund for purposes
of Section 860G(a)(2) of the Code.

     The parties intend that the affairs of the REMIC I
Trust Fund formed hereunder shall constitute, and that the
affairs of the REMIC I Trust Fund shall be conducted so as
to qualify the REMIC I Trust Fund as a REMIC. In furtherance
of such intention, the Company covenants and agrees that it
shall act as agent for the Tax Matters Person (and the
Company is hereby appointed to act as agent for such Tax
Matters Person) on behalf of the REMIC I Trust Fund and that
in such capacity it shall: (a) prepare and file, or cause to
be prepared and filed, a federal tax return using a calendar
year as the taxable year and using an accrual method of
accounting for the REMIC I Trust Fund when and as required
by the REMIC Provisions and other applicable federal income
<PAGE>



<PAGE> 143

tax laws; (b) make an election, on behalf of the trust, for
the REMIC I Trust Fund to be treated as a REMIC on the
federal tax return of the REMIC I Trust Fund for its first
taxable year, in accordance with the REMIC Provisions; (c)
prepare and forward, or cause to be prepared and forwarded,
to the Holders of the REMIC I Regular Interests and the
Class R-1 Certificates and the Trustee, all information
reports as and when required to be provided to them in
accordance with the REMIC Provisions, and make available the
information necessary for the application of Section 860E(e)
of the Code; (d) conduct the affairs of the REMIC I Trust
Fund at all times that any REMIC I Regular Interests are
outstanding so as to maintain the status of the REMIC I
Trust Fund as a REMIC under the REMIC Provisions; (e) not
knowingly or intentionally take any action or omit to take
any action that would cause the termination of the REMIC
status of the REMIC I Trust Fund; and (f) pay the amount of
any federal prohibited transaction penalty taxes imposed on
the REMIC I Trust Fund when and as the same shall be due and
payable (but such obligation shall not prevent the Company
or any other appropriate person from contesting any such tax
in appropriate proceedings and shall not prevent the Company
from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings); provided, that the
Company shall be entitled to be indemnified by the REMIC I
Trust Fund for any such prohibited transaction penalty taxes
if the Company's failure to exercise reasonable care was not
the primary cause of the imposition of such prohibited
transaction penalty taxes.

     The Trustee and the Master Servicer shall promptly
provide the Company with such information as the Company may
from time to time request for the purpose of enabling the
Company to prepare tax returns.

     In the event that a Mortgage Loan is discovered to have
a defect which, had such defect been discovered before the
startup day, would have prevented such Mortgage Loan from
being a "qualified mortgage" within the meaning of Section
860G(a)(3) of the Code, and the Company does not repurchase
such Mortgage Loan within 90 days of such date, the Master
Servicer, on behalf of the Trustee, shall within 90 days of
the date such defect is discovered sell such Mortgage Loan
at such price as the Master Servicer in its sole discretion,
determines to be the greatest price that will result in the
purchase thereof within 90 days of such date, unless the
Master Servicer delivers to the Trustee an Opinion of
Counsel to the effect that continuing to hold such Mortgage
Loan will not adversely affect the status of the electing
portion of the REMIC I Trust Fund as a REMIC for federal
income tax purposes.

<PAGE>



<PAGE> 144

     In the event that any tax is imposed on "prohibited
transactions" of the REMIC I Trust Fund as defined in
Section 860F of the Code and not paid by the Company
pursuant to clause (f) of the third preceding paragraph,
such tax shall be charged against amounts otherwise
distributable to the Class R-1 Certificateholders.
Notwithstanding anything to the contrary contained herein,
the Trustee is hereby authorized to retain from amounts
otherwise distributable to the Class R-1 Certificateholders
on any Distribution Date sufficient funds to reimburse the
Company in its capacity as agent for the Tax Matters Person
for the payment of such tax (upon the written request of the
Company, to the extent reimbursable, and to the extent that
the Company has not been previously reimbursed therefor).

     Section 2.02.  Acceptance by Trustee. The Trustee
acknowledges receipt (or with respect to any Mortgage Loan
subject to a Custodial Agreement, receipt by the Custodian
thereunder) of the documents (or certified copies thereof as
specified in Section 2.01) referred to in Section 2.01
above, but without having made the review required to be
made within 45 days pursuant to this Section 2.02, and
declares that as of the Closing Date it holds and will hold
such documents and the other documents constituting a part
of the Mortgage Files delivered to it, and the Trust Fund,
as Trustee in trust, upon the trusts herein set forth, for
the use and benefit of the Holders from time to time of the
REMIC I Regular Interests and Class R-1 Certificates. The
Trustee agrees, for the benefit of the Holders of the REMIC
I Regular Interests and Class R-1 Certificates, to review or
cause the Custodian to review each Mortgage File within 45
days after the Closing Date and deliver to the Company a
certification in the form attached as Exhibit M hereto, to
the effect that all documents required (in the case of
instruments described in clauses (X)(v) and (Y)(x) of the
definition of "Mortgage File", known by the Trustee to be
required) pursuant to the third paragraph of Section 2.01
have been executed and received, and that such documents
relate to the Mortgage Loans identified in the Mortgage Loan
Schedule. In performing such review, the Trustee may rely
upon the purported genuineness and due execution of any such
document, and on the purported genuineness of any signature
thereon. The Trustee shall not be required to make any
independent examination of any documents contained in each
Mortgage File beyond the review specifically required
herein. The Trustee makes no representations as to: (i) the
validity, legality, enforceability or genuineness of any of
the Mortgage Loans identified on the Mortgage Loan Schedule,
or (ii) the collectability, insurability, effectiveness or
suitability of any Mortgage Loan. If the Trustee finds any
document or documents constituting a part of a Mortgage File
not to have been executed or received, or to be unrelated to
<PAGE>



<PAGE> 145

the Mortgage Loans identified in the Mortgage Loan Schedule,
the Trustee shall promptly so notify the Company. The
Company hereby covenants and agrees that, if any such defect
cannot be corrected or cured, the Company shall, not later
than 60 days after the Trustee's notice to it respecting
such defect, within the three-month period commencing on the
Closing Date (or within the two-year period commencing on
the Closing Date if the related Mortgage Loan is a
"defective obligation" within the meaning of Section
860G(a)(4)(B)(ii) of the Code and Treasury Regulation
Section 1.860G-2(f)), either (i) repurchase the related
Mortgage Loan from the Trustee at the Purchase Price, or
(ii) substitute for any Mortgage Loan to which such defect
relates a different mortgage loan (a "Substitute Mortgage
Loan") which is a "qualified replacement mortgage" (as
defined in the Code) and, (iii) after such three-month or
two-year period, as applicable, the Company shall repurchase
the Mortgage Loan from the Trustee at the Purchase Price but
only if the Mortgage Loan is in default or default is, in
the judgment of the Company, reasonably imminent. If such
defect would cause the Mortgage Loan to be other than a
"qualified mortgage" (as defined in the Code), then
notwithstanding the previous sentence, repurchase or
substitution must occur within the sooner of (i) 90 days
from the date the defect was discovered or (ii) in the case
of substitution, two years from the Closing Date.

     Such Substitute Mortgage Loan shall mature no later
than, and not more than two years earlier than, have a
principal balance and Loan-to-Value Ratio equal to or less
than, and have a Pass-Through Rate on the date of
substitution equal to or no more than 1% greater than the
Mortgage Loan being substituted for. If the aggregate of the
principal balances of the Substitute Mortgage Loans
substituted for a Mortgage Loan is less than the Principal
Balance of such Mortgage Loan, the Company shall pay the
difference in cash to the Trustee for deposit into the
Certificate Account, and such payment by the Company shall
be treated in the same manner as proceeds of the repurchase
by the Company of a Mortgage Loan pursuant to this Section
2.02. Furthermore, such Substitute Mortgage Loan shall
otherwise have such characteristics so that the
representations and warranties of the Company set forth in
Section 2.03 hereof would not have been incorrect had such
Substitute Mortgage Loan originally been a Mortgage Loan,
and the Company shall be deemed to have made such
representations and warranties as to such Substitute
Mortgage Loan. A Substitute Mortgage Loan may be substituted
for a defective Mortgage Loan whether or not such defective
Mortgage Loan is itself a Substitute Mortgage Loan.

     The Purchase Price for each repurchased Mortgage Loan
<PAGE>



<PAGE> 146

shall be deposited by the Company in the Certificate Account
and, upon receipt by the Trustee of written notification of
such deposit signed by a Servicing Officer, the Trustee
shall release to the Company the related Mortgage File and
shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as shall be
necessary to vest in the Company or its designee or assignee
title to any Mortgage Loan released pursuant hereto. The
obligation of the Company to repurchase or substitute any
Mortgage Loan as to which such a defect in a constituent
document exists shall constitute the sole remedy respecting
such defect available to the Holders of the REMIC I Regular
Interests or the Class R-1 Certificateholders or the Trustee
on behalf of the Holders of the REMIC I Regular Interests or
the Class R-1 Certificateholders.

     It is understood and agreed that the representations
and warranties set forth in this Section 2.03 shall survive
delivery of the respective Mortgage Files to the Trustee or
the Custodian, as the case may be, and shall continue
throughout the term of this Agreement. Upon discovery by any
of the Company, the Master Servicer, the Trustee or the
Custodian of a breach of any of the foregoing
representations and warranties which materially and
adversely affects the value of the related Mortgage Loans or
the interests of the Certificateholders in the related
Mortgage Loans, the Company, the Master Servicer, the
Trustee or the Custodian, as the case may be, discovering
such breach shall give prompt written notice to the others.
Within 90 days of its discovery or its receipt of notice of
breach, the Company shall repurchase, subject to the
limitations set forth in the definition of "Purchase Price",
or substitute for the affected Mortgage Loan or Mortgage
Loans or any property acquired in respect thereof from the
Trustee, unless it has cured such breach in all material
respects. After the end of the three-month period beginning
on the "start-up day", any such substitution shall be made
only if the Company provides to the Trustee and the
Certificate Insurer an Opinion of Counsel reasonably
satisfactory to the Trustee that each Substitute Mortgage
Loan will be a "qualified replacement mortgage" within the
meaning of Section 860G(a)(4) of the Code. Such substitution
shall be made in the manner and within the time limits set
forth in Section 2.02. Any such repurchase by the Company

Price, if applicable, but shall not be subject to the time
limits, set forth in Section 2.02. It is understood and
agreed that the obligation of the Company to provide such
<PAGE>



<PAGE> 152

substitution or to make such repurchase of any affected
Mortgage Loan or Mortgage Loans or any property acquired in
respect thereof as to which a breach has occurred and is
continuing shall constitute the sole remedy respecting such
breach available to the Holders of the REMIC I Regular
Interests and the Class R-1 Certificateholders or the
Trustee on behalf of the Holders of the REMIC I Regular
Interests and the Class R-1 Certificateholders.

     Section 2.04.  Acknowledgment of Transfer of Trust Fund;
Authentication of the Class R-1 Certificates. The Trustee
acknowledges the transfer and assignment to it of the
property constituting the Trust Fund, but without having
made the review required to be made within 45 days pursuant
to Section 2.02, and, as of the Closing Date, shall cause to
be authenticated and delivered to or upon the order of the
Company, the Class R-1 Certificates in Authorized
Denominations evidencing the residual beneficial ownership
interest in the REMIC I Trust Fund.

     Section 2.05.  Conveyance of REMIC II; REMIC Election and
Designations.  A trust ("REMIC II") of which the Trustee is
the trustee is hereby created under the laws of the State of
New York for the benefit of the Holders of the REMIC II
Regular Interests and the Class R-2 Certificates.  The
purpose of REMIC II is to hold the REMIC II Trust Fund and
provide for the issuance, execution and delivery of the
REMIC II Regular Interests and the Class R-2 Certificates.
The assets of REMIC II shall consist of the REMIC II Trust
Fund.  REMIC II shall be irrevocable.

     The assets of REMIC II shall remain in the custody of
the Trustee, on behalf of REMIC II, and shall be kept in
REMIC II.  Moneys to the credit of REMIC II shall be held by
the Trustee and invested as provided herein.  All assets
received and held in REMIC II will not be subject to any
right, charge, security interest, lien or claim of any kind
in favor of State Street Bank and Trust Company in its own
right, or any Person claiming through it.  The Trustee, on
behalf of REMIC II, shall not have the power or authority to
transfer, assign, hypothecate, pledge or otherwise dispose
of any of the assets of REMIC II to any Person, except as
permitted herein.  No creditor of a beneficiary of REMIC II,
of the Trustee, of the Master Servicer or of the Company
shall have any right to obtain possession of, or otherwise
exercise legal or equitable remedies with respect to, the
property of REMIC II, except in accordance with the terms of
this Agreement.

     Concurrently with the execution and delivery hereof,
the Company does hereby agree to irrevocably sell, transfer,
assign, set over, and otherwise convey to the Trustee in
<PAGE>



<PAGE> 153

trust for the benefit of the Holders of the REMIC II Regular
Interests and the Class R-2 Certificates, without recourse,
all the Company's right, title and interest in and to the
REMIC II Trust Fund, including all interest and principal
received by the Company on or with respect to the REMIC I
Regular Interests after the Cut-Off Date. The Trustee hereby
accepts REMIC II created hereby and accepts delivery of the
REMIC II Trust Fund on behalf of REMIC II and acknowledges
that it holds the REMIC I Regular Interests for the benefit
of the Holders of the REMIC II Regular Interests and the
Class R-2 Certificates issued pursuant to this Agreement. It
is the express intent of the parties hereto that the
conveyance of the REMIC II Trust Fund to the Trustee by the
Company as provided in this Section 2.05 be, and be
construed as, an absolute sale of the REMIC II Trust Fund.
It is, further, not the intention of the parties that such
conveyance be deemed a pledge of the REMIC II Trust Fund by
the Company to the Trustee to secure a debt or other
obligation of the Company. However, in the event that,
notwithstanding the intent of the parties, the REMIC II
Trust Fund is held to be the property of the Company, or if
for any other reason this Agreement is held or deemed to
create a security interest in the REMIC II Trust Fund, then

     (a)  this Agreement shall be deemed to be a security
agreement;

     (b)  the conveyance provided for in this Section 2.05
shall be deemed to be a grant by the Company to the Trustee

and interest, whether now owned or hereafter acquired, in

     therein attributable to the Mortgage Loans); (iii) the
     Certificate Insurance Policy, the CMAC Policy and
     amounts paid or payable by the insurer under any FHA
     insurance policy or any Primary Insurance Policy and
     proceeds of any VA guaranty and any other insurance
     policy related to any Mortgage Loan or the Mortgage
     Pool; (iv) all property or rights arising from or by
     virtue of the disposition of, or collections with
     respect to, or insurance proceeds payable with respect
     to, or claims against other persons with respect to,
     all or any part of the collateral described in (i)-
     (iii) above (including any accrued discount realized on
     liquidation of any investment purchased at a discount),
     and (v) all cash and non-cash proceeds of the
     collateral described in (i)-(iv) above;
     
          (II) All accounts, general intangibles, chattel
     paper, instruments, documents, money, deposit accounts,

     payable with respect to, or claims against other
     persons with respect to, all or any part of the
     collateral described in (I) above (including any
     accrued discount realized on liquidation of any
     investment purchased at a discount); and
     
          (III)     All cash and non-cash proceeds of the
     collateral described in (I) and (II) above;
     
     (c)  the possession by the Trustee of the Mortgage
Notes, the Mortgages and such other goods, letters of
credit, advices of credit, instruments, money, documents,
chattel paper or certificated securities shall be deemed to
be possession by the secured party or possession by a
purchaser for purposes of perfecting the security interest
pursuant to the Uniform Commercial Code (including, without
limitation, Sections 9-305 and 9-115 thereof) as in force in
the relevant jurisdiction; and

     (d)  notifications to persons holding such property,
and acknowledgments, receipts or confirmations from persons
holding such property, shall be deemed notifications to, or
acknowledgments, receipts or confirmations from, securities
intermediaries, bailees or agents of, or persons holding
for, the Trustee, as applicable for the purpose of
perfecting such security interest under applicable law.

     The Company and the Trustee shall, to the extent
consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to
<PAGE>



<PAGE> 155

create a security interest in the REMIC II Trust Fund, such
security interest would be deemed to be a perfected security
interest of first priority under applicable law and will be
maintained as such throughout the term of this Agreement. In
connection herewith, the Trustee shall have all of the
rights and remedies of a secured party and creditor under
the Uniform Commercial Code as in force in the relevant
jurisdiction.

     The Trustee is authorized, with the Master Servicer's
consent, to appoint any bank or trust company approved by
and unaffiliated with each of the Company and the Master
Servicer as Custodian of the documents or instruments
referred to above in this Section 2.05, and to enter into a
Custodial Agreement for such purpose; provided, however,
that the Trustee shall be and remain liable for actions of
any such Custodian only to the extent it would otherwise be
responsible for such acts hereunder.

     The Company and the Trustee agree that the Company, on
behalf of the REMIC II Trust Fund, shall elect to treat the
REMIC II Trust Fund as a REMIC within the meaning of Section
860D of the Code and, if necessary, under applicable state
laws. Such election shall be included in the Form 1066 and
any appropriate state return to be filed on behalf of the
REMIC constituted by the REMIC II Trust Fund for its first
taxable year.

     The Closing Date is hereby designated as the "startup
day" of the REMIC constituted by the REMIC II Trust Fund
within the meaning of Section 860G(a)(9) of the Code.

     The regular interests (as set forth in the table
contained in the Preliminary Statement hereto) relating to
the REMIC II Trust Fund are hereby designated as "regular
interests" for purposes of Section 860G(a)(1) of the Code.
The Class R-2 Certificates are being issued in a single
Class, which is hereby designated as the sole class of
"residual interest" in the REMIC II Trust Fund for purposes
of Section 860G(a)(2) of the Code.

     The parties intend that the affairs of the REMIC II
Trust Fund formed hereunder shall constitute, and that the
affairs of the REMIC II Trust Fund shall be conducted so as
to qualify it as, a REMIC. In furtherance of such intention,
the Company covenants and agrees that it shall act as agent
for the Tax Matters Person (and the Company is hereby
appointed to act as Tax Matters Person) on behalf of the
REMIC II Trust Fund and that in such capacity it shall: (a)
prepare and file, or cause to be prepared and filed, a
federal tax return using a calendar year as the taxable year
for the REMIC II Trust Fund when and as required by the
<PAGE>



<PAGE> 156

REMIC provisions and other applicable federal income tax
laws; (b) make an election, on behalf of the REMIC II Trust
Fund, to be treated as a REMIC on the federal tax return of
the REMIC II Trust Fund for its first taxable year, in
accordance with the REMIC provisions; (c) prepare and
forward, or cause to be prepared and forwarded, to the
Holders of the REMIC II Regular Interests and the Class R-2
Certificates all information reports as and when required to
be provided to them in accordance with the REMIC provisions;
(d) conduct the affairs of the REMIC II Trust Fund at all
times that any of the REMIC II Regular Interests and the
Class R-2 Certificates are outstanding so as to maintain the
status of the REMIC II Trust Fund as a REMIC under the REMIC
provisions; (e) not knowingly or intentionally take any
action or omit to take any action that would cause the
termination of the REMIC status of the REMIC II Trust Fund;
and (f) pay the amount of any federal prohibited transaction
penalty taxes imposed on the REMIC II Trust Fund when and as
the same shall be due and payable (but such obligation shall
not prevent the Company or any other appropriate person from
contesting any such tax in appropriate proceedings and shall
not prevent the Company from withholding payment of such
tax, if permitted by law, pending the outcome of such
proceedings); provided, that the Company shall be entitled
to be indemnified from the REMIC II Trust Fund for any such
prohibited transaction penalty taxes if the Company's
failure to exercise reasonable care was not the primary
cause of the imposition of such prohibited transaction
penalty taxes.

     In the event that any tax is imposed on "prohibited
transactions" of the REMIC II Trust Fund as defined in
Section 860F of the Code and not paid by the Company
pursuant to clause (f) of the preceding paragraph, such tax
shall be charged against amounts otherwise distributable to
the Holders of the Class R-2 Certificates. Notwithstanding
anything to the contrary contained herein, the Company is
hereby authorized to retain from amounts otherwise
distributable to the Holders of the Class R-2 Certificates
on any Distribution Date sufficient funds to reimburse the
Company for the payment of such tax (to the extent that the
Company has not been previously reimbursed therefor).

     Section 2.06.  Acceptance by Trustee; Authentication of
Certificates. The Trustee acknowledges and accepts the
assignment to it of the property constituting the REMIC II
Trust Fund and declares that as of the Closing Date it holds
and shall hold any documents constituting a part of the
REMIC II Trust Fund, and the REMIC II Trust Fund, as Trustee
in trust, upon the trusts herein set forth, for the use and
benefit of all present and future Holders of the REMIC II
Regular Interests and the Class R-2 Certificates.  In
<PAGE>



<PAGE> 157

connection therewith, as of the Closing Date, the Trustee
shall cause to be authenticated and delivered to or upon the
order of the Company, in exchange for the property
constituting the REMIC II Trust Fund, the Class R-2
Certificates in Authorized Denominations evidencing the
residual ownership interest in the REMIC II Trust Fund.

     Section 2.07.  Conveyance of REMIC III; REMIC Election and
Designations. A trust ("REMIC III") of which the Trustee is
the trustee is hereby created under the laws of the State of
New York for the benefit of the Holders of the Certificates
(other than the Class R-1 and Class R-2 Certificates).  The
purpose of REMIC III is to hold the REMIC III Trust Fund and
provide for the issuance, execution and delivery of the
Certificates (other than the Class R-1 and Class R-2
Certificates).  The assets of REMIC III shall consist of the
REMIC III Trust Fund.  REMIC III shall be irrevocable.

     The assets of REMIC III shall remain in the custody of
the Trustee, on behalf of REMIC III, and shall be kept in
REMIC III.  Moneys to the credit of REMIC III shall be held
by the Trustee and invested as provided herein.  All assets
received and held in REMIC III will not be subject to any
right, charge, security interest, lien or claim of any kind
in favor of State Street Bank and Trust Company in its own
right, or any Person claiming through it.  The Trustee, on
behalf of REMIC III, shall not have the power or authority
to transfer, assign, hypothecate, pledge or otherwise
dispose of any of the assets of REMIC III to any Person,
except as permitted herein.  No creditor of a beneficiary of
REMIC III, of the Trustee, of the Master Servicer or of the
Company shall have any right to obtain possession of, or
otherwise exercise legal or equitable remedies with respect
to, the property of REMIC III, except in accordance with the
terms of this Agreement.

     Concurrently with the execution and delivery hereof,
the Company does hereby agree to irrevocably sell, transfer,
assign, set over, and otherwise convey to the Trustee in
trust for the benefit of the Certificateholders (other than
the Class R-1 and Class R-2 Certificateholders), without
recourse, all the Company's right, title and interest in and
to the REMIC III Trust Fund, including all interest and
principal received by the Company on or with respect to the
REMIC II Regular Interests after the Cut-Off Date. The
Trustee hereby accepts REMIC III created hereby and accepts
delivery of the REMIC III Trust Fund on behalf of REMIC III
and acknowledges that it holds the REMIC II Regular
Interests for the benefit of the Holders of the Certificates
(other than the Class R-1 and Class R-2 Certificates) issued
pursuant to this Agreement. It is the express intent of the
parties hereto that the conveyance of the REMIC III Trust
<PAGE>



<PAGE> 158

Fund to the Trustee by the Company as provided in this
Section 2.07 be, and be construed as, an absolute sale of
the REMIC III Trust Fund. It is, further, not the intention
of the parties that such conveyance be deemed a pledge of
the REMIC III Trust Fund by the Company to the Trustee to
secure a debt or other obligation of the Company. However,
in the event that, notwithstanding the intent of the
parties, the REMIC III Trust Fund is held to be the property
of the Company, or if for any other reason this Agreement is
held or deemed to create a security interest in the REMIC
III Trust Fund, then

     (a)  this Agreement shall be deemed to be a security
agreement;

     (b)  the conveyance provided for in this Section 2.07
shall be deemed to be a grant by the Company to the Trustee
of a security interest in all of the Company's right, title,
and interest, whether now owned or hereafter acquired, in
and to:

          (I)  All accounts, contract rights, general
     intangibles, chattel paper, instruments, documents,
     money, deposit accounts, certificates of deposit,
     goods, letters of credit, advices of credit and
     investment property consisting of, arising from or
     relating to any of the property described below: The
     uncertificated REMIC II Regular Interests, including
     without limitation all rights represented thereby in
     and to (i) the Mortgage Loans identified on the
     Mortgage Loan Schedule, including the related Mortgage
     Notes, Mortgages, Cooperative Stock Certificates, and
     Cooperative Leases, all Substitute Mortgage Loans and
     all distributions with respect to such Mortgage Loans
     and Substitute Mortgage Loans payable on and after the
     Cut-Off Date, (ii) the Certificate Account, the
     Investment Account, the Class I-A-14 Rounding Account
     and all money or other property held therein and the
     Custodial Accounts for P&I and the Custodial Accounts
     for Reserves (to the extent of the amounts on deposit
     therein attributable to the Mortgage Loans); (iii) the
     Certificate Insurance Policy, the CMAC Policy and any
     amounts paid or payable by the insurer under any FHA
     insurance policy or any Primary Insurance Policy and
     proceeds of any VA guaranty and any other insurance
     policy related to any Mortgage Loan or the Mortgage
     Pool; (iv) all property or rights arising from or by
     virtue of the disposition of, or collections with
     respect to, or insurance proceeds payable with respect
     to, or claims against other persons with respect to,
     all or any part of the collateral described in (i)-
     (iii) above (including any accrued discount realized on
<PAGE>



<PAGE> 159

     liquidation of any investment purchased at a discount),
     and (v) all cash and non-cash proceeds of the
     collateral described in (i)-(iv) above;
     
          (II) All accounts, general intangibles, chattel
     paper, instruments, documents, money, deposit accounts,
     certificates of deposit, goods, letters of credit,
     advices of credit, investment property and other rights
     arising from or by virtue of the disposition of, or
     collections with respect to, or insurance proceeds
     payable with respect to, or claims against other
     persons with respect to, all or any part of the
     collateral described in (I) above (including any
     accrued discount realized on liquidation of any
     investment purchased at a discount); and
     
          (III)     All cash and non-cash proceeds of the
     collateral described in (I) and (II) above;
     
     (c)  the possession by the Trustee of the Mortgage
Notes, the Mortgages and such other goods, letters of
credit, advices of credit, instruments, money, documents,
chattel paper or certificated securities shall be deemed to
be possession by the secured party or possession by a
purchaser for purposes of perfecting the security interest
pursuant to the Uniform Commercial Code (including, without
limitation, Sections 9-305 and 9-115 thereof) as in force in
the relevant jurisdiction; and

     (d)  notifications to persons holding such property,
and acknowledgments, receipts or confirmations from persons
holding such property, shall be deemed notifications to, or
acknowledgments, receipts or confirmations from, securities
intermediaries, bailees or agents of, or persons holding
for, the Trustee, as applicable for the purpose of
perfecting such security interest under applicable law.

     The Company and the Trustee shall, to the extent
consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to
create a security interest in the REMIC III Trust Fund, such
security interest would be deemed to be a perfected security
interest of first priority under applicable law and will be
maintained as such throughout the term of this Agreement. In
connection herewith, the Trustee shall have all of the
rights and remedies of a secured party and creditor under
the Uniform Commercial Code as in force in the relevant
jurisdiction.

     The Trustee is authorized, with the Master Servicer's
consent, to appoint any bank or trust company approved by
and unaffiliated with each of the Company and the Master
<PAGE>



<PAGE> 160

Servicer as Custodian of the documents or instruments
referred to above in this Section 2.07, and to enter into a
Custodial Agreement for such purpose; provided, however,
that the Trustee shall be and remain liable for actions of
any such Custodian only to the extent it would otherwise be
responsible for such acts hereunder.

     The Company and the Trustee agree that the Company, on
behalf of the REMIC III Trust Fund, shall elect to treat the
REMIC III Trust Fund as a REMIC within the meaning of
Section 860D of the Code and, if necessary, under applicable
state laws. Such election shall be included in the Form 1066
and any appropriate state return to be filed on behalf of
the REMIC constituted by the REMIC III Trust Fund for its
first taxable year.

     The Closing Date is hereby designated as the "startup
day" of the REMIC constituted by the REMIC III Trust Fund
within the meaning of Section 860G(a)(9) of the Code.

     The regular interests (as set forth in the table
contained in the Preliminary Statement hereto) relating to
the REMIC III Trust Fund are hereby designated as "regular
interests" for purposes of Section 860G(a)(1) of the Code.
The Class R-3 Certificates are being issued in a single
Class, which is hereby designated as the sole class of
"residual interest" in the REMIC III Trust Fund for purposes
of Section 860G(a)(2) of the Code.

     The parties intend that the affairs of the REMIC III
Trust Fund formed hereunder shall constitute, and that the
affairs of the REMIC III Trust Fund shall be conducted so as
to qualify it as, a REMIC. In furtherance of such intention,
the Company covenants and agrees that it shall act as agent
for the Tax Matters Person (and the Company is hereby
appointed to act as Tax Matters Person) on behalf of the
REMIC III Trust Fund and that in such capacity it shall: (a)
prepare and file, or cause to be prepared and filed, a
federal tax return using a calendar year as the taxable year
for the REMIC III Trust Fund when and as required by the
REMIC provisions and other applicable federal income tax
laws; (b) make an election, on behalf of the REMIC III Trust
Fund, to be treated as a REMIC on the federal tax return of
the REMIC III Trust Fund for its first taxable year, in
accordance with the REMIC provisions; (c) prepare and
forward, or cause to be prepared and forwarded, to the
Certificateholders (other than the Class R-1 and Class R-2
Certificateholders) all information reports as and when
required to be provided to them in accordance with the REMIC
provisions; (d) conduct the affairs of the REMIC III Trust
Fund at all times that any Certificates are outstanding so
as to maintain the status of the REMIC III Trust Fund as a
<PAGE>



<PAGE> 161

REMIC under the REMIC provisions; (e) not knowingly or
intentionally take any action or omit to take any action
that would cause the termination of the REMIC status of the
REMIC III Trust Fund; and (f) pay the amount of any federal
prohibited transaction penalty taxes imposed on the REMIC
III Trust Fund when and as the same shall be due and payable
(but such obligation shall not prevent the Company or any
other appropriate person from contesting any such tax in
appropriate proceedings and shall not prevent the Company
from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings); provided, that the
Company shall be entitled to be indemnified from the REMIC
III Trust Fund for any such prohibited transaction penalty
taxes if the Company's failure to exercise reasonable care
was not the primary cause of the imposition of such
prohibited transaction penalty taxes.

     In the event that any tax is imposed on "prohibited
transactions" of the REMIC III Trust Fund as defined in
Section 860F of the Code and not paid by the Company
pursuant to clause (f) of the preceding paragraph, such tax
shall be charged against amounts otherwise distributable to
the Holders of the Class R-3 Certificates. Notwithstanding
anything to the contrary contained herein, the Company is
hereby authorized to retain from amounts otherwise
distributable to the Holders of the Class R-3 Certificates
on any Distribution Date sufficient funds to reimburse the
Company for the payment of such tax (to the extent that the
Company has not been previously reimbursed therefor).

     Section 2.08.  Acceptance by Trustee; Authentication of
Certificates. The Trustee acknowledges and accepts the
assignment to it of the property constituting the REMIC III
Trust Fund and declares that as of the Closing Date it holds
and shall hold any documents constituting a part of the
REMIC III Trust Fund, and the REMIC III Trust Fund, as
Trustee in trust, upon the trusts herein set forth, for the
use and benefit of all present and future Certificateholders
(other than the Class R-1 and Class R-2 Certificateholders).
In connection therewith, as of the Closing Date, the Trustee
shall cause to be authenticated and delivered to or upon the
order of the Company, in exchange for the property
constituting the REMIC III Trust Fund, the Certificates
(other than the Class R-1 and Class R-2 Certificates) in
Authorized Denominations evidencing the entire ownership of
the REMIC III Trust Fund.

       Administration and Servicing of Mortgage Loans
                              
     Section 3.01.  The Company to Act as Master Servicer.  The
<PAGE>



<PAGE> 162

Company shall act as Master Servicer to service and
administer the Mortgage Loans on behalf of the Trustee and
for the benefit of the Certificateholders in accordance with
the terms hereof and in the same manner in which, and with
the same care, skill, prudence and diligence with which, it
services and administers similar mortgage loans for other
portfolios, and shall have full power and authority to do or
cause to be done any and all things in connection with such
servicing and administration which it may deem necessary or
desirable, including, without limitation, the power and
authority to bring actions and defend REMIC I, REMIC II and
REMIC III on behalf of the Trustee in order to enforce the
terms of the Mortgage Notes.  The Master Servicer may
perform its master servicing responsibilities through agents
or independent contractors, but shall not thereby be
released from any of its responsibilities hereunder and the
Master Servicer shall diligently pursue all of its rights
against such agents or independent contractors.

     The Master Servicer shall make reasonable efforts to
collect or cause to be collected all payments called for
under the terms and provisions of the Mortgage Loans and
shall, to the extent such procedures shall be consistent
with this Agreement and the terms and provisions of any
Primary Insurance Policy, the CMAC Policy, any FHA insurance
policy or VA guaranty, any hazard insurance policy, and
federal flood insurance, cause to be followed such
collection procedures as are followed with respect to
mortgage loans comparable to the Mortgage Loans and held in
portfolios of responsible mortgage lenders in the local
areas where each Mortgaged Property is located. The Master
Servicer shall enforce "due-on-sale" clauses with respect to
the related Mortgage Loans, to the extent permitted by law,
subject to the provisions set forth in Section 3.08.

     Consistent with the foregoing, the Master Servicer may
in its discretion (i) waive or cause to be waived any
assumption fee or late payment charge in connection with the
prepayment of any Mortgage Loan and (ii) only upon
determining that the coverage of any applicable insurance
policy or guaranty related to a Mortgage Loan will not be
materially adversely affected, arrange a schedule, running
for no more than 180 days after the first delinquent Due
Date, for payment of any delinquent installment on any
Mortgage Note or for the liquidation of delinquent items.
The Master Servicer shall have the right, but not the
obligation, to repurchase any related delinquent Mortgage
Loan 90 days after the first delinquent Due Date for an
amount equal to its Purchase Price; provided, however, that
the aggregate Purchase Price of Mortgage Loans so
repurchased shall not exceed one-half of one percent (0.50%)
of the aggregate Principal Balance, as of the Cut-Off Date,
<PAGE>



<PAGE> 163

of all Mortgage Loans.

     Consistent with the terms of this Section 3.01, the
Master Servicer may waive, modify or vary any term of any
Mortgage Loan or consent to the postponement of strict
compliance with any such term or in any manner grant
indulgence to any Mortgagor if it has determined, exercising
its good faith business judgment in the same manner as it
would if it were the owner of the related Mortgage Loan,
that the security for, and the timely and full
collectability of, such Mortgage Loan would not be adversely
affected by such waiver, modification, postponement or
indulgence; provided, however, that (unless the Mortgagor is
in default with respect to the Mortgage Loan or in the
reasonable judgment of the Master Servicer such default is
imminent) the Master Servicer shall not permit any
modification with respect to any Mortgage Loan that would
(i) change the applicable Mortgage Interest Rate, defer or
forgive the payment of any principal or interest, reduce the
outstanding principal balance (except for actual payments of
principal) or extend the final maturity date with respect to
such Mortgage Loan, or (ii) be inconsistent with the terms
of any applicable Primary Insurance Policy, FHA insurance
policy, VA guaranty, hazard insurance policy or federal
flood insurance policy or the CMAC Policy. Notwithstanding
the foregoing, the Master Servicer shall not permit any
modification with respect to any Mortgage Loan that would
both constitute a sale or exchange of such Mortgage Loan
within the meaning of Section 1001 of the Code (including
any proposed, temporary or final regulations promulgated
thereunder) (other than in connection with a proposed
conveyance or assumption of such Mortgage Loan that is
treated as a Principal Prepayment or in a default situation)
and cause any REMIC to fail to qualify as such under the
Code.

     The Master Servicer is hereby authorized and empowered
by the Trustee to execute and deliver or cause to be
executed and delivered on behalf of the Holders of the REMIC
I Regular Interests and the Class R-1 Certificateholders,
and the Trustee or any of them, any and all instruments of
satisfaction or cancellation, or of partial or full release,
discharge or modification, assignments of Mortgages and
endorsements of Mortgage Notes in connection with
refinancings (in jurisdictions where such assignments are
the customary and usual standard of practice of mortgage
lenders) and all other comparable instruments, with respect
to the Mortgage Loans and with respect to the Mortgaged
Properties. The Trustee shall execute and furnish to the
Master Servicer, at the Master Servicer's direction, any
powers of attorney and other documents prepared by the
Master Servicer and determined by the Master Servicer to be
<PAGE>



<PAGE> 164

necessary or appropriate to enable the Master Servicer to
carry out its supervisory, servicing and administrative
duties under this Agreement.

     The Master Servicer and each Servicer shall obtain (to
the extent generally commercially available from time to
time) and maintain fidelity bond and errors and omissions
coverage acceptable to FNMA or FHLMC with respect to their
obligations under this Agreement and the applicable Selling
and Servicing Contract, respectively. The Master Servicer or
each Servicer, as applicable, shall establish escrow
accounts for, or pay when due (by means of an advance), any
tax liens in connection with the Mortgaged Properties that
are not paid by the Mortgagors when due to the extent that
any such payment would not constitute a Nonrecoverable
Advance when made. Notwithstanding the foregoing, the Master
Servicer shall not permit any modification with respect to
any Mortgage Loan that would both constitute a sale or
exchange of such Mortgage Loan within the meaning of Section
1001 of the Code (including any proposed, temporary or final
regulations promulgated thereunder) (other than in
connection with a proposed conveyance or assumption of such
Mortgage Loan that is treated as a Principal Prepayment or
in a default situation) and cause any of the REMICs to fail
to qualify as such under the Code. The Master Servicer shall
be entitled to approve a request from a Mortgagor for a
partial release of the related Mortgaged Property, the
granting of an easement thereon in favor of another Person,
any alteration or demolition of the related Mortgaged
Property or other similar matters if it has determined,
exercising its good faith business judgment in the same
manner as it would if it were the owner of the related
Mortgage Loan, that the security for, and the timely and
full collectability of, such Mortgage Loan would not be
adversely affected thereby and that the applicable trust
fund would not fail to continue to qualify as a REMIC under
the Code as a result thereof and that no tax on "prohibited
transactions" or "contributions" after the startup day would
be imposed on either REMIC as a result thereof.

     In connection with the servicing and administering of
each Mortgage Loan, the Master Servicer and any affiliate of
the Master Servicer (i) may perform services such as
appraisals, default management and brokerage services that
are not customarily provided by servicers of mortgage loans,
and shall be entitled to reasonable compensation therefor
and (ii) may, at its own discretion and on behalf of the
Trustee, obtain credit information in the form of a "credit
score" from a credit repository.

     Section 3.02.  Custodial Accounts. The Master Servicer shall
cause to be established and maintained by each Servicer
<PAGE>



<PAGE> 165

under the Master Servicer's supervision the Custodial
Account for P&I, Buydown Fund Accounts (if any) and special
Custodial Account for Reserves and shall deposit or cause to
be deposited therein daily the amounts related to the
Mortgage Loans required by the Selling and Servicing
Contracts to be so deposited. Proceeds received with respect
to individual Mortgage Loans from any title, hazard, or FHA
insurance policy, VA guaranty, Primary Insurance Policy, the
CMAC Policy or other insurance policy covering such Mortgage
Loans shall be deposited first in the Custodial Account for
Reserves if required for the restoration or repair of the
related Mortgaged Property. Proceeds from such insurance
policies not so deposited in the Custodial Account for
Reserves shall be deposited in the Custodial Account for
P&I, and shall be applied to the balances of the related
Mortgage Loans as payments of interest and principal.

     The Master Servicer is hereby authorized to make
withdrawals from and to issue drafts against the Custodial
Accounts for P&I and the Custodial Accounts for Reserves for
the purposes required or permitted by this Agreement. Each
Custodial Account for P&I and each Custodial Account for
Reserves shall bear a designation clearly showing the
respective interests of the applicable Servicer, as trustee,
and of the Master Servicer, in substantially one of the
following forms:

          (a)  With respect to the Custodial Account for
     P&I: (i) [Servicer's Name], as agent, trustee and/or
     bailee of principal and interest custodial account for
     PNC Mortgage Securities Corp., its successors and
     assigns, for various owners of interests in PNC
     Mortgage Securities Corp. mortgage-backed pools or (ii)
     [Servicer's Name] in trust for PNC Mortgage Securities
     Corp.;
     
          (b)  With respect to the Custodial Account for
     Reserves: (i) [Servicer's Name], as agent, trustee
     and/or bailee of taxes and insurance custodial account
     for PNC Mortgage Securities Corp., its successors and
     assigns for various mortgagors and/or various owners of
     interests in PNC Mortgage Securities Corp. mortgage-
     backed pools or (ii) [Servicer's Name] in trust for PNC
     Mortgage Securities Corp. and various Mortgagors.
     
     The Master Servicer hereby undertakes to assure
remittance to the Certificate Account of all amounts
relating to the Mortgage Loans that have been collected by
any Servicer and are due to the Certificate Account pursuant
to Section 4.01 of this Agreement.

     Section 3.03.  The Investment Account; Eligible

<PAGE> 166

Investments.(a)     Not later than the Withdrawal Date, the
Master Servicer shall withdraw or direct the withdrawal of
funds in the Custodial Accounts for P&I, for deposit in the
Investment Account, in an amount representing:

          (i)  Scheduled installments of principal and
     interest on the Mortgage Loans received or advanced by
     the applicable Servicers which were due on the related
     Due Date, net of Servicing Fees due the applicable
     Servicers and less any amounts to be withdrawn later by
     the applicable Servicers from the applicable Buydown
     Fund Accounts;
     
          (ii) Payoffs and the proceeds of other types of
     liquidations of the Mortgage Loans received by the
     applicable Servicer for such Mortgage Loans during the
     applicable Payoff Period, with interest to the date of
     Payoff or liquidation less any amounts to be withdrawn
     later by the applicable Servicers from the applicable
     Buydown Fund Accounts; and
     
          (iii)     Curtailments received by the applicable
     Servicers in the Prior Period.
     
     At its option, the Master Servicer may invest funds
withdrawn from the Custodial Accounts for P&I, as well as
any Buydown Funds, Insurance Proceeds and Liquidation
Proceeds previously received by the Master Servicer
(including amounts paid by the Company in respect of any
Purchase Obligation or its substitution obligations set
forth in Section 2.02 or Section 2.03 or in connection with
the exercise of the option to terminate this Agreement
pursuant to Section 9.01) for its own account and at its own
risk, during any period prior to their deposit in the
Certificate Account. Such funds, as well as any funds which
were withdrawn from the Custodial Accounts for P&I on or
before the Withdrawal Date, but not yet deposited into the
Certificate Account, shall immediately be deposited by the
Master Servicer with the Investment Depository in an
Investment Account in the name of the Master Servicer and
the Trustee for investment only as set forth in this Section
3.03. The Master Servicer shall bear any and all losses
incurred on any investments made with such funds and shall
be entitled to retain all gains realized on such investments
as additional servicing compensation. Not later than the
Business Day prior to the Distribution Date, the Master
Servicer shall deposit such funds, net of any gains (except
Payoff Earnings) earned thereon, in the Certificate Account.

     (b)  Funds held in the Investment Account shall be

in no event mature later than the Business Day prior to the

related Distribution Date (except if such Eligible
Investments are obligations of the Trustee, such Eligible
Investments may mature on the Distribution Date), or (ii)
such other instruments as shall be required to maintain the
Ratings.

     Section 3.04.  The Certificate Account.

     (a)  Not later than the Business Day prior to the
related Distribution Date, the Master Servicer shall direct
the Investment Depository to deposit the amounts previously
deposited into the Investment Account (which may include a
deposit of Eligible Investments) to which the Holders of the
REMIC I Regular Interests, the Class R-1 Certificateholders
and the Certificate Insurer are entitled into the
Certificate Account. In addition, not later than the
Business Day prior to the Distribution Date, the Master
Servicer shall deposit into the Certificate Account any
Monthly P&I Advances or other payments required to be made

Purchase Obligation or in connection with the exercise of
its option to terminate this Agreement pursuant to Section
9.01) not previously deposited in the Custodial Accounts for
P&I or the Investment Account. The Trustee shall deposit

Certificate Insurance Policy in accordance with Section
3.22(b) hereof.

     (b)  Funds held in the Certificate Account shall be
invested at the direction of the Master Servicer in (i) one
or more Eligible Investments which shall in no event mature
later than the Business Day prior to the related
Distribution Date (except if such Eligible Investments are
obligations of the Trustee, such Eligible Investments may
mature on the Distribution Date), or (ii) such other
instruments as shall be required to maintain the Ratings.
The Master Servicer shall be entitled to receive any gains
earned on such Eligible Investments and shall bear any
losses suffered in connection therewith.

     Section 3.05.  Permitted Withdrawals from the Certificate
Account, the Investment Account and Custodial Accounts for
P&I and of Buydown Funds from the Buydown Fund Accounts.

     (a)  The Master Servicer is authorized to make
withdrawals, from time to time, from the Investment Account,
the Certificate Account or the Custodial Accounts for P&I
established by the Servicers of amounts deposited therein in
respect of the Certificates, as follows:

<PAGE>



<PAGE> 168

          (i)  To reimburse itself or the applicable
     Servicer for Monthly P&I Advances made pursuant to
     Section 4.02 or a Selling and Servicing Contract, such
     right to reimbursement pursuant to this paragraph (i)
     being limited to amounts received on particular
     Mortgage Loans (including, for this purpose, Insurance
     Proceeds and Liquidation Proceeds) which represent late
     recoveries of principal and/or interest respecting
     which any such Monthly P&I Advance was made;
     
          (ii) To reimburse itself or the applicable
     Servicer for amounts expended by or for the account of
     the Master Servicer pursuant to Section 3.09 or amounts
     expended by such Servicer pursuant to the Selling and
     Servicing Contracts in connection with the restoration
     of property damaged by an Uninsured Cause or in
     connection with the liquidation of a Mortgage Loan;
     
          (iii)     To pay to itself, with respect to the
     related Mortgage Loans, the Master Servicing Fee (net
     of Compensating Interest reduced by Payoff Earnings and
     Payoff Interest) as to which no prior withdrawals from
     funds deposited by the Master Servicer have been made;
     
          (iv) To reimburse itself or the applicable
     Servicer for advances made with respect to related
     Mortgage Loans which the Master Servicer has determined
     to be Nonrecoverable Advances;
     
          (v)  To pay to itself reinvestment earnings
     deposited or earned in the Investment Account and the
     Certificate Account to which it is entitled and to
     reimburse itself for expenses incurred by and
     reimbursable to it pursuant to Section 6.03;
     
          (vi) To deposit to the Investment Account amounts
     in the Certificate Account not required to be on
     deposit therein at the time of such withdrawal;
     
          (vi) To deposit in the Certificate Account, not
     later than the Business Day prior to the related
     Distribution Date, the amounts specified in Section
     3.04(a); and
     
     after making or providing for the above withdrawals

          (vii)     To clear and terminate the Investment
     Account and the Certificate Account following
     termination of this Agreement pursuant to Section 9.01.
     
     Since, in connection with withdrawals pursuant to
paragraphs (i) and (ii), the Master Servicer's entitlement
<PAGE>



<PAGE> 169

thereto is limited to collections or other recoveries on the
related Mortgage Loan, the Master Servicer or the applicable
Servicer shall keep and maintain separate accounting for
each Mortgage Loan, for the purpose of justifying any such
withdrawals.

     (b)  The Master Servicer (or the applicable Servicer,
if such Servicer holds and maintains a Buydown Fund Account)
is authorized to make withdrawals, from time to time, from
the Buydown Fund Account or Custodial Account for P&I
established by any Servicer under its supervision of the
following amounts of Buydown Funds:

          (i)  To deposit each month in the Investment
     Account the amount necessary to supplement payments
     received on Buydown Loans;
     
          (ii) In the event of a Payoff of any Mortgage Loan
     having a related Buydown Fund, to apply amounts
     remaining in Buydown Fund Accounts to reduce the
     required amount of such principal Payoff (or, if the
     Mortgagor has made a Payoff, to refund such remaining
     Buydown Fund amounts to the Person entitled thereto);
     
          (iii)     In the event of foreclosure or
     liquidation of any Mortgage Loan having a Buydown Fund,
     to deposit remaining Buydown Fund amounts in the
     Investment Account as Liquidation Proceeds; and
     
          (iv) To clear and terminate the portion of any
     account representing Buydown Funds following
     termination of this Agreement pursuant to Section 9.01;
     
     (c)  The Trustee is authorized to make withdrawals from
time to time from the Certificate Account to reimburse
itself for advances it has made pursuant to Section 7.01(a)
hereof that it has determined to be Nonrecoverable Advances.

     Section 3.06.  Maintenance of Primary Insurance Policies;
Collections Thereunder. The Master Servicer shall use
commercially reasonable efforts to keep, and to cause the
Servicers to keep, in full force and effect each Primary
Insurance Policy and the CMAC Policy required with respect
to a Mortgage Loan, in the manner set forth in the
applicable Selling and Servicing Contract, until no longer
required. Notwithstanding the foregoing, the Master Servicer
shall have no obligation to maintain any Primary Insurance
Policy for a Mortgage Loan for which the outstanding
Principal Balance thereof at any time subsequent to
origination was 80% or less of the value of the related
Mortgaged Property (as determined by the appraisal obtained
at the time of origination), unless required by applicable
<PAGE>



<PAGE> 170

law.

     Unless required by applicable law, the Master Servicer
shall not cancel or refuse to renew, or allow any Servicer
under its supervision to cancel or refuse to renew, any such
Primary Insurance Policy or the CMAC Policy in effect at the
date of the initial issuance of the Certificates that is
required to be kept in force hereunder; provided, however,
that neither the Master Servicer nor any Servicer shall
advance funds for the payment of any premium due under any
Primary Insurance Policy or the CMAC Policy if it shall
determine that such an advance would be a Nonrecoverable
Advance.

     Section 3.07.  Maintenance of Hazard Insurance. The Master
Servicer shall cause to be maintained for each Mortgage Loan
(other than a Cooperative Loan) fire insurance with extended
coverage in an amount which is not less than the original
principal balance of such Mortgage Loan, except in cases
approved by the Master Servicer in which such amount exceeds
the value of the improvements to the Mortgaged Property. The
Master Servicer shall also require fire insurance with
extended coverage in a comparable amount on property
acquired upon foreclosure, or deed in lieu of foreclosure,
of any Mortgage Loan (other than a Cooperative Loan). Any
amounts collected under any such policies (other than
amounts to be applied to the restoration or repair of the
related Mortgaged Property) shall be deposited into the
Custodial Account for P&I, subject to withdrawal pursuant to
the applicable Selling and Servicing Contract and pursuant
to Section 3.03 and Section 3.05. Any unreimbursed costs
incurred in maintaining any insurance described in this
Section 3.07 shall be recoverable as an advance by the
Master Servicer from the Investment Account or the
Certificate Account. Such insurance shall be with insurers
approved by the Master Servicer and FNMA or FHLMC. Other
additional insurance may be required of a Mortgagor, in
addition to that required pursuant to such applicable laws
and regulations as shall at any time be in force and as
shall require such additional insurance. Where any part of
any improvement to the Mortgaged Property (other than a
Mortgaged Property secured by a Cooperative Loan) is located
in a federally designated special flood hazard area and in a
community which participates in the National Flood Insurance
Program at the time of origination of the related Mortgage
Loan, the Master Servicer shall cause flood insurance to be
provided. The hazard insurance coverage required by this
Section 3.07 may be met with blanket policies providing
protection equivalent to individual policies otherwise
required. The Master Servicer or the applicable Servicer
shall be responsible for paying any deductible amount on any
such blanket policy. The Master Servicer agrees to present,
<PAGE>



<PAGE> 171

or cause to be presented, on behalf of and for the benefit
of the Trustee and Certificateholders, claims under the
hazard insurance policy respecting any Mortgage Loan, and in
this regard to take such reasonable actions as shall be
necessary to permit recovery under such policy.

     Section 3.08.  Enforcement of Due-on-Sale Clauses;
Assumption Agreements. When any Mortgaged Property is about
to be conveyed by the Mortgagor, the Master Servicer shall,
to the extent it has knowledge of such prospective
conveyance and prior to the time of the consummation of such
conveyance, exercise on behalf of the Trustee the Trustee's
rights to accelerate the maturity of such Mortgage Loan, to
the extent that such acceleration is permitted by the terms
of the related Mortgage Note, under any "due-on-sale" clause
applicable thereto; provided, however, that the Master
Servicer shall not exercise any such right if the due-on-
sale clause, in the reasonable belief of the Master
Servicer, is not enforceable under applicable law or if such
exercise would result in non-coverage of any resulting loss
that would otherwise be covered under any insurance policy.
In the event the Master Servicer is prohibited from
exercising such right, the Master Servicer is authorized to
take or enter into an assumption and modification agreement
from or with the Person to whom a Mortgaged Property has
been or is about to be conveyed, pursuant to which such
Person becomes liable under the Mortgage Note and, unless
prohibited by applicable state law or unless the Mortgage
Note contains a provision allowing a qualified borrower to
assume the Mortgage Note, the Mortgagor remains liable
thereon; provided that the Mortgage Loan shall continue to
be covered (if so covered before the Master Servicer enters
such agreement) by any related Primary Insurance Policy or
the CMAC Policy, if applicable. The Master Servicer is also
authorized to enter into a substitution of liability
agreement with such Person, pursuant to which the original
Mortgagor is released from liability and such Person is
substituted as Mortgagor and becomes liable under the
Mortgage Note.  The Master Servicer shall not enter into any
substitution or assumption with respect to a Mortgage Loan
if such substitution or assumption shall (i) both constitute
a "significant modification" effecting an exchange or
reissuance of such Mortgage Loan under the Code (or Treasury
regulations promulgated thereunder) and cause the REMICs to
fail to qualify as a REMIC under the REMIC Provisions or
(ii) cause the imposition of any tax on "prohibited
transactions" or "contributions" after the startup day under
the REMIC Provisions.  The Master Servicer shall notify the
Trustee that any such substitution or assumption agreement
has been completed by forwarding to the Trustee the original
copy of such substitution or assumption agreement and other
documents and instruments constituting a part thereof. In
<PAGE>



<PAGE> 172

connection with any such assumption or substitution
agreement, the terms of the related Mortgage Note shall not
be changed. Any fee collected by the applicable Servicer for
entering into an assumption or substitution of liability
agreement shall be retained by such Servicer as additional
servicing compensation.

     Notwithstanding the foregoing paragraph or any other
provision of this Agreement, the Master Servicer shall not
be deemed to be in default, breach or any other violation of
its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or any assumption which
the Master Servicer may be restricted by law from
preventing, for any reason whatsoever.

     Section 3.09.  Realization Upon Defaulted Mortgage Loans.
The Master Servicer shall foreclose upon or otherwise
comparably convert, or cause to be foreclosed upon or
comparably converted, the ownership of any Mortgaged
Property securing a Mortgage Loan which comes into and
continues in default and as to which no satisfactory
arrangements can be made for collection of delinquent
payments pursuant to Section 3.01. In lieu of such
foreclosure or other conversion, and taking into
consideration the desirability of maximizing net Liquidation
Proceeds after taking into account the effect of Insurance
Proceeds upon Liquidation Proceeds, the Master Servicer may,
to the extent consistent with prudent mortgage loan
servicing practices, accept a payment of less than the
outstanding Principal Balance of a delinquent Mortgage Loan
in full satisfaction of the indebtedness evidenced by the
related Mortgage Note and release the lien of the related
Mortgage upon receipt of such payment. The Master Servicer
shall not foreclose upon or otherwise comparably convert a
Mortgaged Property if the Master Servicer is aware of
evidence of toxic waste, other hazardous substances or other
evidence of environmental contamination thereon and the
Master Servicer determines that it would be imprudent to do
so. In connection with such foreclosure or other conversion,
the Master Servicer shall cause to be followed such
practices and procedures as it shall deem necessary or
advisable and as shall be normal and usual in general
mortgage servicing activities. The foregoing is subject to
the provision that, in the case of damage to a Mortgaged
Property from an Uninsured Cause, the Master Servicer shall
not be required to advance its own funds towards the
restoration of the property unless it shall be determined in
the sole judgment of the Master Servicer, (i) that such
restoration will increase the proceeds of liquidation of the
Mortgage Loan to Certificateholders after reimbursement to
itself for such expenses, and (ii) that such expenses will
be recoverable to it through Liquidation Proceeds. The
<PAGE>



<PAGE> 173

Master Servicer shall be responsible for all other costs and
expenses incurred by it in any such proceedings; provided,
however, that it shall be entitled to reimbursement thereof
(as well as its normal servicing compensation) as an
advance. The Master Servicer shall maintain information
required for tax reporting purposes regarding any Mortgaged
Property which is abandoned or which has been foreclosed or
otherwise comparably converted. The Master Servicer shall
report such information to the Internal Revenue Service and
the Mortgagor in the manner required by applicable law.

     With respect to each of the Group C-B Certificates and
the Group I-B Certificates, the Master Servicer may enter
into a special servicing agreement with an unaffiliated
holder of a 100% Percentage Interest of the Class B
Certificate with the lowest priority or a holder of a 100%
interest in a class of securities representing such
interests in such Class, subject to each Rating Agency's
acknowledgment that the Ratings of the Certificates in
effect immediately prior to the entering into of such
agreement would not be qualified, downgraded or withdrawn
and the Certificates would not be placed on credit review
status (except for possible upgrading) as a result of such
agreement.  Any such agreement may contain provisions
whereby such holder may (a) instruct the Master Servicer to
instruct a Servicer to the extent provided in the applicable
Selling and Servicing Contract to commence or delay
foreclosure proceedings with respect to delinquent Mortgage
Loans and will contain provisions for the deposit of cash
with the Master Servicer by the holder that would be
available for distribution to Certificateholders if
Liquidation Proceeds are less than they otherwise may have
been had the Servicer acted in accordance with its normal
procedures or (b) purchase delinquent Mortgage Loans from
the REMIC I Trust Fund immediately prior to the commencement
of foreclosure proceedings at a price equal to the aggregate
outstanding Principal Balance of such Mortgage Loans plus
accrued interest thereon at the applicable Mortgage Interest
Rate through the last day of the month in which such
Mortgage Loan is purchased and/or (c) assume all of the
servicing rights and obligations with respect to delinquent
Mortgage Loans so long as (i) the Master Servicer has the
right to transfer the servicing rights and obligations of
such Mortgage Loans to another servicer and (ii) such holder
will service such Mortgage Loans in accordance with the
applicable Selling and Servicing Contract.

     REMIC I shall not acquire any real property (or
personal property incident to such real property) except in
connection with a default or imminent default of a Mortgage
Loan. In the event that REMIC I acquires any real property
(or personal property incident to such real property) in
<PAGE>



<PAGE> 174

connection with a default or imminent default of a Mortgage
Loan, such property shall be disposed of by the Master
Servicer within two years after its acquisition by the
Master Servicer for REMIC I, unless the Master Servicer
provides to the Trustee and the Certificate Insurer an
Opinion of Counsel to the effect that the holding by REMIC I
of such Mortgaged Property subsequent to two years after its
acquisition will not result in the imposition of taxes on
"prohibited transactions" of REMIC I as defined in Section
860F of the Code or under the law of any state in which real
property securing a Mortgage Loan owned by REMIC I is
located or cause REMIC I to fail to qualify as a REMIC for
federal income tax purposes or for state tax purposes under
the laws of any state in which real property securing a
Mortgage Loan owned by REMIC I is located at any time that
any Certificates are outstanding. The Master Servicer shall
manage, conserve, protect and operate each such property for
the Certificateholders solely for the purpose of its prompt
disposition and sale in a manner which does not cause such
property to fail to qualify as "foreclosure property" within
the meaning of Section 860G(a)(8) or result in the receipt
by the REMIC of any "income from non-permitted assets"
within the meaning of Section 860F(a)(2)(B) of the Code or
any "net income from foreclosure property" which is subject
to taxation under the REMIC Provisions. Pursuant to its
efforts to sell such property, the Master Servicer shall
either itself or through an agent selected by the Master
Servicer protect and conserve such property in the same
manner and to such extent as is customary in the locality
where such property is located and may, incident to its
conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as
the Master Servicer deems to be in the best interest of the
Master Servicer and the Certificateholders for the period
prior to the sale of such property. Additionally, the Master
Servicer shall perform the tax withholding and shall file
information returns with respect to the receipt of mortgage
interests received in a trade or business, the reports of
foreclosures and abandonments of any Mortgaged Property and
the information returns relating to cancellation of
indebtedness income with respect to any Mortgaged Property
required by Sections 6050H, 6050J and 6050P, respectively,
of the Code, and deliver to the Trustee an Officers'
Certificate on or before March 31 of each year stating that
such reports have been filed.  Such reports shall be in form
and substance sufficient to meet the reporting requirements
imposed by Sections 6050H, 6050J and 6050P of the Code.

     Notwithstanding any other provision of this Agreement,
the Master Servicer and the Trustee, as applicable, shall
comply with all federal withholding requirements with
respect to payments to Certificateholders of interest or
<PAGE>



<PAGE> 175

original issue discount that the Master Servicer or the
Trustee reasonably believes are applicable under the Code.
The consent of Certificateholders shall not be required for
any such withholding.  Without limiting the foregoing, the
Master Servicer agrees that it will not withhold with
respect to payments of interest or original issue discount
in the case of a Certificateholder that has furnished or
caused to be furnished an effective Form W-8 or an
acceptable substitute form or a successor form and who is
not a "10 percent shareholder" within the meaning of Code
Section 871(h)(3)(B) or a "controlled foreign corporation"
described in Code Section 881(c)(3)(C) with respect to REMIC
I, REMIC II, REMIC III or the  Depositor.  In the event the
Trustee withholds any amount from interest or original issue
discount payments or advances thereof to any
Certificateholder pursuant to federal withholding
requirements, the Trustee shall indicate the amount withheld
to such Certificateholder.

     Section 3.10.  Trustee to Cooperate; Release of Mortgage
Files. Upon the Payoff or scheduled maturity of any Mortgage
Loan, the Master Servicer shall cause such final payment to
be immediately deposited in the related Custodial Account
for P&I or the Investment Account. Upon notice thereof, the
Master Servicer shall promptly notify the Trustee by a
certification (which certification shall include a statement
to the effect that all amounts received in connection with
such payment which are required to be deposited in either
such account have been so deposited) of a Servicing Officer
and shall request delivery to it of the Mortgage File. Upon
receipt of such certification and request, the Trustee
shall, not later than the fifth succeeding Business Day,
release the related Mortgage File to the Master Servicer or
the applicable Servicer indicated in such request. With any
such Payoff or other final payment, the Master Servicer is
authorized to prepare for and procure from the trustee or
mortgagee under the Mortgage which secured the Mortgage Note
a deed of full reconveyance or other form of satisfaction or
assignment of Mortgage and endorsement of Mortgage Note in
connection with a refinancing covering the Mortgaged
Property, which satisfaction, endorsed Mortgage Note or
assigning document shall be delivered by the Master Servicer
to the person or persons entitled thereto. No expenses
incurred in connection with such satisfaction or assignment
shall be payable to the Master Servicer by the Trustee or
from the Certificate Account, the related Investment Account
or the related Custodial Account for P&I. From time to time
as appropriate for the servicing or foreclosure of any
Mortgage Loan, including, for this purpose, collection under
any Primary Insurance Policy and the CMAC Policy, the
Trustee shall, upon request of the Master Servicer and
delivery to it of a trust receipt signed by a Servicing
<PAGE>



<PAGE> 176

Officer, release not later than the fifth Business Day
following the date of receipt of such request the related
Mortgage File to the Master Servicer or the related Servicer
as indicated by the Master Servicer and shall execute such
documents as shall be necessary to the prosecution of any
such proceedings. Such trust receipt shall obligate the
Master Servicer to return the Mortgage File to the Trustee
when the need therefor by the Master Servicer no longer
exists, unless the Mortgage Loan shall be liquidated, in
which case, upon receipt of a certificate of a Servicing
Officer similar to that herein above specified, the trust
receipt shall be released by the Trustee to the Master
Servicer.

     Section 3.11.  Compensation to the Master Servicer and the
Servicers. As compensation for its activities hereunder, the
Master Servicer shall be entitled to receive from the
Investment Account or the Certificate Account the amounts
provided for by Section 3.05(a)(iii). The Master Servicer
shall be required to pay all expenses incurred by it in
connection with its activities hereunder and shall not be
entitled to reimbursement therefor, except as specifically
provided herein.

     As compensation for its activities under the applicable
Selling and Servicing Contract, the applicable Servicer
shall be entitled to withhold or withdraw from the related
Custodial Account for P&I the amounts provided for in such
Selling and Servicing Contract. Each Servicer is required to
pay all expenses incurred by it in connection with its
servicing activities under its Selling and Servicing
Contract (including payment of premiums for Primary
Insurance Policies, if required) and shall not be entitled
to reimbursement therefor except as specifically provided in
such Selling and Servicing Contract and not inconsistent
with this Agreement.

     Section 3.12.  Reports to the Trustee; Certificate Account
Statement. Not later than 15 days after each Distribution
Date, the Master Servicer shall forward a statement,
certified by a Servicing Officer, to the Trustee and the
Certificate Insurer setting forth the status of the
Certificate Account as of the close of business on such
Distribution Date and showing, for the period covered by
such statement, the aggregate of deposits into and
withdrawals from the Certificate Account for each category
of deposit specified in Section 3.04 and each category of
withdrawal specified in Section 3.05, and stating that all
distributions required by this Agreement have been made (or
if any required distribution has not been made, specifying
the nature and amount thereof).  The Trustee shall provide
such statements to any Certificateholder upon request at the
<PAGE>



<PAGE> 177

expense of the Master Servicer.  Such statement shall also,
to the extent available, include information regarding
delinquencies on the Mortgage Loans, indicating the number
and aggregate Principal Balance of Mortgage Loans which are
one, two, three or more months delinquent, the number and
aggregate Principal Balance of Mortgage Loans with respect
to which foreclosure proceedings have been initiated and the
book value of any Mortgaged Property acquired by the REMIC I
Trust Fund through foreclosure, deed in lieu of foreclosure
or other exercise of the REMIC I Trust Fund's security
interest in the Mortgaged Property.

     Section 3.13.  Annual Statement as to Compliance. The Master
Servicer shall deliver to the Trustee and the Certificate
Insurer, on or before April 30 of each year, beginning with
the first April 30 succeeding the Cut-Off Date by at least
six months, an Officer's Certificate stating as to the
signer thereof, that (i) a review of the activities of the
Master Servicer during the preceding calendar year and
performance under this Agreement has been made under such
officer's supervision, and (ii) to the best of such
officer's knowledge, based on such review, the Master
Servicer has fulfilled all its obligations under this
Agreement throughout such year, or, if there has been a
default in the fulfillment of any such obligation,
specifying each such default known to such officer and the
nature and status thereof. Copies of such statement shall be
provided by the Master Servicer to Certificateholders upon
request or by the Trustee (solely to the extent that such
copies are available to the Trustee) at the expense of the
Master Servicer, should the Master Servicer fail to so
provide such copies.

     Section 3.14.  Access to Certain Documentation and
Information Regarding the Mortgage Loans. In the event that
the Certificates are legal for investment by federally-
insured savings associations, the Master Servicer shall
provide to the OTS, the FDIC and the supervisory agents and
examiners of the OTS and the FDIC access to the
documentation regarding the related Mortgage Loans required
by applicable regulations of the OTS or the FDIC, as
applicable, and shall in any event provide such access to
the documentation regarding such Mortgage Loans to the
Trustee and its representatives, such access being afforded
without charge, but only upon reasonable request and during
normal business hours at the offices of the Master Servicer
designated by it.

     Section 3.15.  Annual Independent Public Accountants'
Servicing Report. On or before April 30 of each year,
beginning with the first April 30 succeeding the Cut-Off
Date by at least six months, the Master Servicer, at its
<PAGE>



<PAGE> 178

expense, shall cause a firm of independent public
accountants to furnish a statement to the Trustee and the
Certificate Insurer to the effect that, in connection with
the firm's examination of the financial statements as of the
previous December 31 of the Master Servicer's parent
corporation (which shall include a limited examination of
the Master Servicer's financial statements), nothing came to
their attention that indicated that the Master Servicer was
not in compliance with Section 3.02, Section 3.03, Section
3.04, Section 3.05, Section 3.11, Section 3.12 and Section
3.13 of this Agreement, except for (i) such exceptions as
such firm believes to be immaterial, and (ii) such other
exceptions as are set forth in such statement.

     Section 3.16.  [Reserved]

     Section 3.17.  [Reserved.]

     Section 3.18.  [Reserved.]

     Section 3.19.  [Reserved.]

     Section 3.20.  Assumption or Termination of Selling and
Servicing Contracts by Trustee. In the event the Master
Servicer, or any successor Master Servicer, shall for any
reason no longer be the Master Servicer (including by reason
of an Event of Default), the Trustee as trustee hereunder or
its designee shall thereupon assume all of the rights and
obligations of the Master Servicer under the Selling and
Servicing Contracts with respect to the related Mortgage
Loans unless the Trustee elects to terminate the Selling and
Servicing Contracts with respect to such Mortgage Loans in
accordance with the terms thereof. The Trustee, its designee
or the successor servicer for the Trustee shall be deemed to
have assumed all of the Master Servicer's interest therein
with respect to the related Mortgage Loans and to have
replaced the Master Servicer as a party to the Selling and
Servicing Contracts to the same extent as if the rights and
duties under the Selling and Servicing Contracts relating to
such Mortgage Loans had been assigned to the assuming party,
except that the Master Servicer shall not thereby be
relieved of any liability or obligations under the Selling
and Servicing Contracts with respect to the Master
Servicer's duties to be performed prior to its termination
hereunder.

     The Master Servicer at its expense shall, upon request
of the Trustee, deliver to the assuming party all documents
and records relating to the Selling and Servicing Contracts
and the Mortgage Loans then being master serviced by the
Master Servicer and an accounting of amounts collected and
held by the Master Servicer and otherwise use its best
<PAGE>



<PAGE> 179

efforts to effect the orderly and efficient transfer of the
rights and duties under the related Selling and Servicing
Contracts relating to such Mortgage Loans to the assuming
party.

     Section 3.21.  Maintenance of the Class I-A-14 Rounding
Account; Collections Thereunder. On or prior to the Closing
Date, the Trustee shall establish and maintain the Class I-A-
14 Rounding Account and DLJ shall deposit $999.99 therein.
On the first Distribution Date with respect to which the
Master Servicer determines that amounts are available out of
the REMIC III Available Distribution Amount for
distributions of principal on the Class I-A-14 Certificates,
and the aggregate amount allocable to such distributions of
principal is not an amount equal to an integral multiple of
$1,000, the Master Servicer shall notify the Trustee in
writing by Noon New York City time two Business Days prior
to such Distribution Date of the Rounding Amount, and the
Trustee shall withdraw from the Class I-A-14 Rounding
Account the applicable Rounding Amount.  On each succeeding
Distribution Date, prior to the earlier of (i) the Group I
Credit Support Depletion Date and (ii) the date on which any
loss is allocated to the Class I-A-14 Certificates by Pro
Rata Allocation, with respect to which the Master Servicer
determines that amounts are available out of the REMIC III
Available Distribution Amount for distributions of principal
on the Class I-A-14 Certificates, the aggregate amount
allocable to such Class will be applied first to replenish
any funds withdrawn from the Class I-A-14 Rounding Account
on prior Distribution Dates which have not been repaid.  If
the remainder of the aggregate amount allocable to
distributions of principal on such Class is not an amount
equal to an integral multiple of $1,000, the Master Servicer
shall notify the Trustee in writing by Noon New York City
time two Business Days prior to such Distribution Date of
the applicable Rounding Amount, and the Trustee shall
withdraw from the Class I-A-14 Rounding Account, to the
extent funds are available therein, the amount so notified
by the Master Servicer.

     Any amounts withdrawn by the Trustee from the Class I-A-
14 Rounding Account shall be deposited in the Certificate
Account for distribution to the Class I-A-14
Certificateholders as described in the immediately preceding
paragraph (and shall be deemed to have been distributed to
the Class I-A-14-L Regular Interests and deposited for their
benefit into the Certificate Account in accordance with
Section 4.01(i)).

     Amounts on deposit in the Class I-A-14 Rounding Account
shall not be invested and shall not be held in an interest-
bearing account.

     On or promptly after the earlier of (i) the Group I
Credit Support Depletion Date and (ii) the date on which any
loss is allocated to the Class I-A-14 Certificates by Pro
Rata Allocation, the Master Servicer shall be entitled to
withdraw and pay to itself as additional servicing
compensation any remaining amounts on deposit in the Class I-
A-14 Rounding Account.

     Section 3.22.  Maintenance of Certificate Insurance Policy;
Collections Thereunder.

     (a)  Prior to Noon New York City time on the third
Business Day prior to each Distribution Date, the Master
Servicer shall determine if a Deficiency Amount for such
Distribution Date exists and, if so, shall immediately
notify the Trustee in writing of such amount; the Trustee,
upon receipt of such notice, shall complete the Notice and
submit such Notice in accordance with the Certificate
Insurance Policy to the Certificate Insurer no later than
12:00 P.M., New York City time, on the second Business Day
immediately preceding each Distribution Date, as a claim for
an Insured Payment in an amount equal to such Deficiency
Amount. If at any time the Trustee receives a certified copy
of an order of an appropriate court that any payment of
principal and interest on the Insured Certificates
constitutes a Preference Amount, the Trustee, at the expense
of the Trust, shall take the actions required on its part by
the terms of the Certificate Insurance Policy to obtain
payment of such Preference Amount by the Certificate
Insurer.

     (b)  Upon receipt of an Insured Payment from the
Certificate Insurer on behalf of the Insured
Certificateholders, the Trustee shall deposit such Insured
Payment in the Certificate Account.  All such amounts on
deposit in the Certificate Account shall remain uninvested.
The Trustee shall include on each Distribution Date any
amounts received by it from or on behalf of the Certificate
Insurer with respect to the Deficiency Amount for such
Distribution Date in the amount distributed to the
applicable Insured Certificateholders pursuant to Section
4.04.  If on any Distribution Date, the Trustee or the
Master Servicer determines (the Master Servicer having
notified the Trustee of such determination) that the
Certificate Insurer has paid more under the Certificate
Insurance Policy than is required by the terms thereof, the
Trustee shall promptly return the excess amount to the
Certificate Insurer.

     (c)  The Trustee shall (i) receive as attorney-in-fact
of each Insured Certificateholder any Insured Payment
delivered to it by the Certificate Insurer and (ii)
<PAGE>



<PAGE> 181

distribute such Insured Payment to such Insured
Certificateholders as set forth in subsection (b) above.
Insured Payments disbursed by the Trustee from proceeds of
the Certificate Insurance Policy shall not be considered
payment by the Trust Fund with respect to the Insured
Certificates, nor shall such disbursement of such Insured
Payments discharge the obligations of the Trust Fund with
respect to the amounts thereof, and the Certificate Insurer
shall become owner of such amounts to the extent covered by
such Insured Payments as the deemed assignee of such Insured
Certificateholders.  The Trustee hereby agrees on behalf of
each Insured Certificateholder (and each Insured
Certificateholder, by its acceptance of its Insured
Certificates, hereby agrees) for the benefit of the
Certificate Insurer that, to the extent the Certificate
Insurer makes Insured Payments, either directly or
indirectly (as by paying through the Trustee), to the
Insured Certificateholders, the Certificate Insurer will be
subrogated to the rights of the Insured Certificateholders
to the extent of such payments and the Trustee shall pay
such amounts to the Certificate Insurer to the extent
included in the REMIC III Distribution Amount (as notified
to the Trustee by the Master Servicer in the written
statement required pursuant to Section 3.21).

     (d)  On each Distribution Date and prior to making any
distributions on such Distribution Date pursuant to Section
4.01, Section 4.04 or Section 4.05, the Trustee shall
withdraw from the Certificate Account and pay to the
Certificate Insurer the Certificate Insurer Premium.

     Payments to Certificateholders; Payment of Expenses
                              
     Section 4.01.  Distributions to Holders of REMIC I Regular
Interests and Class R-1 Certificateholders.  On each
Distribution Date, the Trustee (or any duly appointed paying
agent) (i) shall be deemed to have distributed from the
Certificate Account the REMIC I Distribution Amount to the
Holders of the REMIC I Regular Interests and to have
deposited such amount for their benefit into the Certificate
Account and (ii) from the Certificate Account shall
distribute (A) to the Class R-1 Certificateholders the sum
of (a) the Excess Liquidation Proceeds and (b) the amounts
to be distributed to the Class R-1 Certificateholders
pursuant to the definition of "REMIC I Distribution Amount"
for such Distribution Date, all in accordance with written
statements received from the Master Servicer pursuant to
Section 4.02(b), by wire transfer in immediately available
funds for the account of each such Holders and the Class R-1
Certificateholder, or by any other means of payment
<PAGE>



<PAGE> 182

acceptable to each such Holder and the Class R-1
Certificateholder of record on the immediately preceding
Record Date (other than as provided in Section 9.01
respecting the final distribution), as specified by each
such Certificateholder and at the address of such Holder
appearing in the Certificate Register. Notwithstanding any
other provision of this Agreement, no actual distributions
pursuant to clause (i) of this Section 4.01 shall be made on
account of the deemed distributions described in this
paragraph except in the event of a liquidation of REMIC III
and REMIC II and not REMIC I.

     Section 4.02.  Advances by the Master Servicer; Distribution
Reports to the Trustee.

     (a)  To the extent described below, the Master Servicer
is obligated to advance its own funds to the Certificate
Account to cover any shortfall between (i) payments
scheduled to be received in respect of Mortgage Loans, and
(ii) the amounts actually deposited in the Certificate
Account on account of such payments; provided that, with
respect to any Balloon Loan that is delinquent on its
maturity date, the Master Servicer will not be required to
advance the related balloon payment but will be required to
continue to make advances in accordance with this Section
4.02 with respect to such Balloon Loan in an amount equal to
one month's interest on the unpaid principal balance at the
applicable Pass-Through Rate for each Distribution Date .
The Master Servicer's obligation to make any advance or
advances described in this Section 4.02 is effective only to
the extent that such advance is, in the good faith judgment
of the Master Servicer made on or before the Business Day
immediately following the Withdrawal Date, reimbursable from
Insurance Proceeds or Liquidation Proceeds of the related
Mortgage Loans or recoverable as late Monthly Payments with
respect to the related Mortgage Loans or otherwise.

     Prior to the close of business on the Business Day
immediately following each Withdrawal Date, the Master
Servicer shall determine whether or not it will make a
Monthly P&I Advance on the Business Day prior to the next
succeeding Distribution Date (in the event that the
applicable Servicer fails to make such advances) and shall
furnish a written statement to the Trustee, the Paying
Agent, if any, and to any Certificateholder requesting the
same, setting forth the aggregate amount to be distributed
on the next succeeding Distribution Date on account of
principal and interest in respect of the Mortgage Loans,
stated separately. In the event that full scheduled amounts
of principal and interest in respect of the Mortgage Loans
shall not have been received by or on behalf of the Master
Servicer prior to such Determination Date and the Master
<PAGE>



<PAGE> 183

Servicer shall have determined that a Monthly P&I Advance
shall be made in accordance with this Section 4.02, the
Master Servicer shall so specify and shall specify the
aggregate amount of such advance.

     In the event that the Master Servicer shall be required
to make a Monthly P&I Advance, it shall on the Business Day
prior to the related Distribution Date either (i) deposit in
the Certificate Account an amount equal to such Monthly P&I
Advance, (ii) make an appropriate entry in the records of
the Certificate Account that funds in such account being
held for future distribution or withdrawal have been, as
permitted by this Section 4.02, used by the Master Servicer
to make such Monthly P&I Advance, or (iii) make advances in
the form of any combination of (i) and (ii) aggregating the
amount of such Monthly P&I Advance. Any funds being held for
future distribution to Certificateholders and so used shall
be replaced by the Master Servicer by deposit in the
Certificate Account on the Business Day immediately
preceding any future Distribution Date to the extent that
funds in the Certificate Account on such Distribution Date
with respect to the Mortgage Loans shall be less than
payments to Certificateholders required to be made on such
date with respect to the Mortgage Loans. Under each Selling
and Servicing Contract, the Master Servicer is entitled to
receive from the Custodial Accounts for P&I established by
the Servicers amounts received by the applicable Servicers
on particular Mortgage Loans as late payments of principal
and interest or as Liquidation or Insurance Proceeds and
respecting which the Master Servicer has made an
unreimbursed advance of principal and interest. The Master
Servicer is also entitled to receive other amounts from the
related Custodial Accounts for P&I established by the
Servicers to reimburse itself for prior Nonrecoverable
Advances respecting Mortgage Loans serviced by such
Servicers. The Master Servicer shall deposit these amounts
in the Investment Account prior to withdrawal pursuant to
Section 3.05.

     In accordance with Section 3.05, Monthly P&I Advances
are reimbursable to the Master Servicer from cash in the
Investment Account or the Certificate Account to the extent
that the Master Servicer shall determine that any such
advances previously made are Nonrecoverable Advances
pursuant to Section 4.03.

     (b)  Prior to Noon New York City time two Business Days
prior to each Distribution Date, the Master Servicer shall
provide the Trustee and the Certificate Insurer with a
statement in writing regarding the amount of the Certificate
Insurer Premium, the amounts to be distributed to the
Certificate Insurer pursuant to the definition of REMIC II
<PAGE>



<PAGE> 184

Distribution Amount, the Deficiency Amount, if any, to be
paid by the Certificate Insurer, the amount, if any, to be
withdrawn from the Class I-A-14 Rounding Account pursuant to
Section 3.21 and the amount of principal and interest, the
Residual Distribution Amount and the Excess Liquidation
Proceeds to be distributed to each Class of REMIC I Regular
Interests, each Class of REMIC II Regular Interests and each
Class of Certificates on such Distribution Date (such
amounts to be determined in accordance with the definitions
of "REMIC I Distribution Amount",  "REMIC II Distribution
Amount" and "REMIC III Distribution Amount", Section 4.01,
Section 4.04 and Section 4.06 hereof and other related
definitions set forth in Article I hereof).

     Section 4.03.  Nonrecoverable Advances. Any advance
previously made by a Servicer pursuant to its Selling and
Servicing Contract with respect to a Mortgage Loan or by the
Master Servicer that the Master Servicer shall determine in
its good faith judgment not to be ultimately recoverable
from Insurance Proceeds or Liquidation Proceeds or otherwise
with respect to such Mortgage Loan or recoverable as late
Monthly Payments with respect to such Mortgage Loan shall be
a Nonrecoverable Advance. The determination by the Master
Servicer that it or the applicable Servicer has made a
Nonrecoverable Advance or that any advance would constitute
a Nonrecoverable Advance, shall be evidenced by an Officer's
Certificate of the Master Servicer delivered to the Trustee
on the Determination Date and detailing the reasons for such
determination.  Notwithstanding any other provision of this
Agreement, any insurance policy relating to the Mortgage
Loans, or any other agreement relating to the Mortgage Loans
to which the Company or the Master Servicer is a party, (a)
the Company, the Master Servicer, and each Servicer shall
not be obligated to, and shall not, make any advance that,
after reasonable inquiry and in its sole discretion, the
Company, the Master Servicer, or such Servicer shall
determine would be a Nonrecoverable Advance, and (b) the
Company, the Master Servicer, and each Servicer shall be
entitled to reimbursement for any advance as provided in
Section 3.05(a)(i), (ii) and (iv) of this Agreement.

     Section 4.04.  Distributions to Holders of REMIC II Regular
Interests and Class R-2 Certificateholders.  On each
Distribution Date, the Trustee (or any duly appointed paying
agent) (i) shall be deemed to have distributed from the
Certificate Account the REMIC II Distribution Amount to the
Holders of the REMIC II Regular Interests and to have
deposited such amount for their benefit into the Certificate
Account and (ii) from the Certificate Account shall
distribute (A) to the Class R-2 Certificateholders the
amounts to be distributed to the Class R-2
Certificateholders pursuant to subsection (I)(e)(xxi) and
<PAGE>



<PAGE> 185

subsection (II)(d)(v) of the definition of "REMIC II
Distribution Amount" for such Distribution Date and (B) to
the Certificate Insurer, the amounts to be distributed to
the Certificate Insurer pursuant to the definition of "REMIC
II Distribution Amount" for such Distribution Date, all in
accordance with written statements received from the Master
Servicer pursuant to Section 4.02(b), by (except with
respect to payments to the Certificate Insurer) wire
transfer in immediately available funds for the account of
each such Holders and the Class R-2 Certificateholder, or by
any other means of payment acceptable to each such Holder
and the Class R-2 Certificateholder of record on the
immediately preceding Record Date (other than as provided in
Section 9.01 respecting the final distribution), as
specified by each such Certificateholder and at the address
of such Holder appearing in the Certificate Register and,
with respect to payments to the Certificate Insurer, by
means of payment acceptable to the Certificate Insurer as
specified by the Certificate Insurer. Notwithstanding any
other provision of this Agreement, no actual distributions
pursuant to clause (i) of this Section 4.04 shall be made on
account of the deemed distributions described in this
paragraph except in the event of a liquidation of REMIC III
and not REMIC II.

     Section 4.05.  Distributions to Certificateholders (other
than Class R-1 and Class R-2 Certificateholders).

     (a)  On each Distribution Date, the Trustee (or any
duly appointed paying agent) shall withdraw from the
Certificate Account, (i) the REMIC III Available
Distribution Amount for such Distribution Date and shall
distribute, from the amount so withdrawn, to the extent of
the REMIC III Available Distribution Amount, the REMIC III
Distribution Amount to the Certificates (other than the
Class R-1 and Class R-2 Certificates and provided that any
portion of such amount distributable to the Class I-A-14
Certificates shall be used first to pay any amount payable
to the Class I-A-14 Rounding Account pursuant to Section
3.21) and to the Certificate Insurer in respect of the
Certificate Insurer's subrogation to certain rights to
payment due to the Insured Certificateholders as set forth
in Section 3.22, (ii) the Deficiency Amount, if any, from
the Certificate Account and distribute such amount to the
Insured Certificateholders and (iii) the Rounding Amount for
distribution on such date pursuant to Section 3.21 and
distribute the amounts so withdrawn to the Class I-A-14
Certificates in accordance with such Section 3.21, all  in
accordance with written statements received from the Master
Servicer pursuant to Section 4.02(b), by (except with
respect to payments to the Certificate Insurer) wire
transfer in immediately available funds for the account of,
<PAGE>



<PAGE> 186

or by check mailed to, each such Certificateholder of record
on the immediately preceding Record Date (other than as
provided in Section 9.01 respecting the final distribution),
as specified by each such Certificateholder and at the
address of such Holder appearing in the Certificate Register
and with respect to payments to the Certificate Insurer, by
means of payment acceptable to the Certificate Insurer.

     (b)  All reductions in the Certificate Principal
Balance of a Certificate effected by distributions of
principal and all allocations of Realized Losses made on any
Distribution Date shall be binding upon all Holders of such
Certificates and of any Certificates issued upon the
registration of transfer or exchange therefor or in lieu
thereof, whether or not such distribution is noted on such
Certificate. The final distribution of principal of each
Certificate (and the final distribution upon the Class R-1
and Class R-2 Certificates upon the termination of REMIC I
and REMIC II) shall be payable in the manner provided above
only upon presentation and surrender thereof on or after the
Distribution Date therefor at the office or agency of the
Certificate Registrar specified in the notice delivered
pursuant to Section 4.05(c)(ii) and Section 9.01(b).

     (c)  Whenever, on the basis of Curtailments, Payoffs,
proceeds of the Certificate Insurance Policy and Monthly
Payments on the Mortgage Loans and Insurance Proceeds and
Liquidation Proceeds received and expected to be received
during the Payoff Period, the Master Servicer has notified
the Trustee that it believes that the entire remaining
unpaid Class Principal Balance of any Class of Certificates
will become distributable on the next Distribution Date, the
Trustee shall, no later than the 18th day of the month of
such Distribution Date, mail or cause to be mailed to each
Person in whose name a Certificate to be so retired is
registered at the close of business on the Record Date and
to the Rating Agencies a notice to the effect that:

          (i)  it is expected that funds sufficient to make
     such final distribution will be available in the
     Certificate Account on such Distribution Date, and
     
          (ii) if such funds are available, (A) such final
     distribution will be payable on such Distribution Date,
     but only upon presentation and surrender of such
     Certificate at the office or agency of the Certificate
     Registrar maintained for such purpose (the address of
     which shall be set forth in such notice), and (B) no
     interest shall accrue on such Certificate after such
     Distribution Date.
     
     Section 4.06.  Statements to Certificateholders. With each
<PAGE>



<PAGE> 187

distribution from the Certificate Account on a Distribution
Date, the Master Servicer shall prepare and forward to the
Trustee (and to the Company if the Company is no longer
acting as Master Servicer), and the Trustee shall forward to
each Certificateholder, a statement setting forth, to the
extent applicable: the amount of the distribution payable to
the applicable Class that represents principal and the
amount that represents interest, and the applicable Class
Principal Balance after giving effect to such distribution.

     Upon request by any Certificateholder or the Trustee,
the Master Servicer shall forward to such Certificateholder,
the Trustee and the Company (if the Company is no longer
acting as Master Servicer) an additional report which sets
forth with respect to the Mortgage Loans:

          (a)  The number and aggregate Principal Balance of
     the Mortgage Loans delinquent one, two and three months
     or more;
     
          (b)  The (i) number and aggregate Principal
     Balance of Mortgage Loans with respect to which
     foreclosure proceedings have been initiated, and (ii)
     the number and aggregate book value of Mortgaged
     Properties acquired through foreclosure, deed in lieu
     of foreclosure or other exercise of rights respecting
     the Trustee's security interest in the Mortgage Loans,
     in each case, by Loan Group;
     
          (c)  The amount of the Group I Special Hazard
     Coverage and the Combined Special Hazard Coverage
     available to the Senior Certificates remaining as of
     the close of business on the applicable Determination
     Date;
     
          (d)  The amount of the Group I Bankruptcy Coverage
     and the Combined Bankruptcy Coverage available to the
     Senior Certificates remaining as of the close of
     business on the applicable Determination Date;
     
          (e)  The amount of the Group I Fraud Coverage and
     Combined Fraud Coverage available to the Senior
     Certificates remaining as of the close of business on
     the applicable  Determination Date;
     
          (f)  The amount of the Class IV-A-5 Reimbursement
     Amount as of the applicable Determination Date, the
     amount of any Preference Amount and any amount payable
     to the Certificate Insurer pursuant to its subrogation
     rights; and
     
          (g)  The amount of Realized Losses incurred in
<PAGE>



<PAGE> 188

     respect of each Loan Group allocable to the
     Certificates on the related Distribution Date and the
     cumulative amount of Realized Losses incurred in
     respect of each Loan Group allocated to such
     Certificates since the Cut-Off Date.
     
     Upon request by any Certificateholder, the Master
Servicer, as soon as reasonably practicable, shall provide
the requesting Certificateholder with such information as is
necessary and appropriate, in the Master Servicer's sole
discretion, for purposes of satisfying applicable reporting
requirements under Rule 144A of the Securities Act.

     Section 4.07.  Principal Distributions on the Class I-A-14
Certificates. (a) Prior to the earlier of (i) the Group I
Credit Support Depletion Date and (ii) the date on which any
loss is allocated to the Class I-A-14 Certificates by Pro
Rata Allocation, distributions in reduction of the Class
Principal Balance of such Class will be made in integral
multiples of $1,000 at the request of the appropriate
representatives of Deceased Holders of Certificates of such
Class and at the request of Living Holders of Certificates
of such Class or by mandatory distributions, pursuant to
Section 4.07(a) and Section 4.07(d). On and after the
earlier of (i) the Group I Credit Support Depletion Date and
(ii) the date on which any loss is allocated to the Class I-
A-14 Certificates by Pro Rata Allocation, distributions in
reduction of the Class Principal Balances of such Class will
be made on a pro rata basis pursuant to Section 4.07(e).

     (a)  On each Distribution Date on which principal
distributions to the Class I-A-14 Certificates are made,
such distributions will be made in the following priority:

          (i)  first, to requesting Deceased Holders, in the order in
     which such requests are received by DTC, but not exceeding
     an aggregate amount of $25,000 for each requesting Deceased
     Holder; and
     
(ii) second, to requesting Living Holders, in the order in
which such requests are received by DTC, but not exceeding
an aggregate amount of $10,000 for each requesting Living
Holder.
Thereafter, distributions will be made, with respect to the
Class I-A-14 Certificates, as provided in clauses (i) and
(ii) above up to a second $25,000 and $10,000, respectively.
This sequence of priorities will be repeated until all
requests for principal distributions by Deceased Holders and
Living Holders of such Class have been honored, to the
extent of amounts available for principal distributions to
such Class.

<PAGE>



<PAGE> 189

     All requests for principal distributions to Class I-A-
14 Certificates will be accepted in accordance with the
provisions set forth in Section 4.07(c). Requests for
principal distributions that are received by the Trustee
after the related Record Date and requests for principal
distributions received in a timely manner but not accepted
with respect to any Distribution Date, will be treated as
requests for principal distributions to the Class I-A-14
Certificates on the next succeeding Distribution Date, and
each succeeding Distribution Date thereafter, until each
such request is accepted or is withdrawn as provided in
Section 4.07(c). Such requests as are not so withdrawn shall
retain their order of priority without the need for any
further action on the part of the appropriate Holder of the
Class I-A-14 Certificate, all in accordance with the
procedures of DTC and the Trustee.  Upon the transfer of
beneficial ownership of any Class I-A-14 Certificate, any
distribution request previously submitted with respect to
such Certificate will be deemed to have been withdrawn only
upon the receipt by the Trustee on or before the Record Date
for such Distribution Date of notification of such
withdrawal in the manner set forth in Section 4.07(c) using
a form required by DTC.

     Distributions in reduction of the Class Principal
Balance of the Class I-A-14 Certificates will be applied in
an amount equal to the portion of the Group I Senior
Principal Distribution Amount allocable to such Class
pursuant to Section 4.05, plus any amounts available for
distribution from the Class I-A-14 Rounding Account
established as provided in Section 3.21, provided that the
aggregate distribution of principal to such Class on any
Distribution Date shall be made in an integral multiple of
$1,000.

     To the extent that the portion of the Group I Senior
Principal Distribution Amount allocable to the Class I-A-14
Certificates on any Distribution Date exceeds the aggregate
Certificate Principal Balance of Class I-A-14 Certificates
with respect to which principal distribution requests, as
set forth above, have been received, principal distributions
in reduction of the Class Principal Balance of such Class
will be made by mandatory distribution pursuant to Section
4.07(d).

     (b)  A Class I-A-14 Certificate shall be deemed to be held
by a Deceased Holder for purposes of this Section 4.07 if
the death of the Holder thereof is deemed to have occurred.
Class I-A-14 Certificates beneficially owned by tenants by
the entirety, joint tenants or tenants in common will be
considered to be beneficially owned by a single owner.  The
death of a tenant by the entirety, joint tenant or tenant in
<PAGE>



<PAGE> 190

common will be deemed to be the death of the Holder, and the
Class I-A-14 Certificates so beneficially owned will be
eligible for priority with respect to principal
distributions, subject to the limitations stated above.
Class I-A-14 Certificates beneficially owned by a trust will
be considered to be beneficially owned by each beneficiary
of the trust to the extent of such beneficiary's beneficial
interest therein, but in no event will a trust's
beneficiaries collectively be deemed to be Holders of a
number of Class I-A-14 Certificates greater than the number
of Class I-A-14 Certificates of which such trust is the
owner.  The death of a beneficiary of a trust will be deemed
to be the death of a Holder of the Class I-A-14 Certificates
beneficially owned by the trust to the extent of such
beneficiary's beneficial interest in such trust.  The death
of an individual who was a tenant by the entirety, joint
tenant or tenant in common in a tenancy which is the
beneficiary of a trust will be deemed to be the death of the
beneficiary of such trust.  The death of a person who,
during his or her lifetime, was entitled to substantially
all of the beneficial ownership interests in a Class I-A-14
Certificate will be deemed to be the death of the Holder of
such Class I-A-14 Certificate regardless of the registration
of ownership, if such beneficial ownership interest can be
established to the satisfaction of the Trustee.  Such
beneficial interest will be deemed to exist in typical cases
of street name or nominee ownership, ownership by a trustee,
ownership under the Uniform Gifts to Minors Act and
community property or other joint ownership arrangements
between a husband and wife.  Beneficial interest shall
include the power to sell, transfer or otherwise dispose of
a Class I-A-14 Certificate and the right to receive the
proceeds therefrom, as well as interest and principal
distributions, as applicable, payable with respect thereto.
The Trustee may rely entirely upon documentation delivered
to it in establishing beneficial ownership interests in
Class I-A-14 Certificates. The Trustee shall not be under
any duty to determine independently the occurrence of the
death of any deceased Holder.  The Trustee may rely entirely
upon documentation delivered to it pursuant to Section
4.07(c) in establishing the eligibility of any Holder to
receive the priority accorded Deceased Holders in Section
4.07(a).

(c)  Requests for principal distributions to any Class I-A-
14 Certificate must be made by delivering a written request
therefor to the DTC Participant or Indirect DTC Participant
that maintains the account evidencing such Holder's interest
in such Certificate.  In the case of a request on behalf of
a Deceased Holder, appropriate evidence of death and any tax
waivers are required to be forwarded to the Trustee under
separate cover.  The DTC Participant should in turn make the
<PAGE>



<PAGE> 191

request of DTC (or, in the case of an Indirect DTC
Participant, such Indirect DTC Participant must notify the
related DTC Participant of such request, which DTC
Participant should make the request of DTC) on a form
required by DTC and provided to the DTC Participant.  Upon
receipt of such request, DTC will date and time stamp such
request and forward such request to the Trustee.  DTC may
establish such procedures as it deems fair and equitable to
establish the order of receipt of requests for such
distributions received by it on the same day.  None of the
Company, the Master Servicer or the Trustee shall be liable
for any delay in delivery of requests for distributions or
withdrawals of such requests by DTC, a DTC Participant or
any Indirect DTC Participant.
     The Trustee shall maintain a list of those DTC
Participants representing the appropriate Holders of Class I-
A-14 Certificates that have submitted requests for principal
distributions, together with the order of receipt and the
amounts of such requests.  Subject to the priorities
described in Section 4.07(a) above, DTC will honor requests
for distributions in the order of their receipt.  The
Trustee shall notify DTC as to which requests should be
honored on each Distribution Date at least two Business Days
prior to such Distribution Date and shall notify DTC as to
the portion of the Group I Senior Principal Distribution
Amount (together with any amounts available for distribution
from the Class I-A-14 Rounding Account) to be distributed to
the Class I-A-14 Certificates by mandatory distribution
pursuant to Section 4.07(d).  Requests shall be honored by
DTC in accordance with the procedures, and subject to the
priorities and limitations, described in this Section 4.07.
The exact procedures to be followed by the Trustee and DTC
for purposes of determining such priorities and limitations
will be those established from time to time by the Trustee
or DTC, as the case may be.  The decisions of the Trustee
and DTC concerning such matters will be final and binding on
all affected persons.

     Class I-A-14 Certificates that have been accepted for a
distribution shall be due and payable on the applicable
Distribution Date.  Such Certificates shall cease to bear
interest after the last calendar day of the month preceding
the month in which such Distribution Date occurs.

     Any Holder of a Class I-A-14 Certificate that has
requested a principal distribution may withdraw its request
by so notifying in writing the DTC Participant or Indirect
DTC Participant that maintains such Holder's account.  In
the event that such account is maintained by an Indirect DTC
Participant, such Indirect DTC Participant must notify the
related DTC Participant which in turn must forward the
withdrawal of such request, on a form required by DTC, to
<PAGE>



<PAGE> 192

DTC to be forwarded to the Trustee.  If such notice of
withdrawal of a request for distribution has not been
received by DTC and forwarded to the Trustee on or before
the Record Date for the next Distribution Date, the
previously made request for a principal distribution will be
irrevocable with respect to the making of principal
distributions on such Distribution Date.

     In the event any requests for principal distributions
are rejected by the Trustee for failure to comply with the
requirements of this Section 4.07, the Trustee shall return
such request to the appropriate DTC Participant with a copy
to DTC with an explanation as to the reason for such
rejection.

     (d)  To the extent, if any, that principal distributions to
be made to the Class I-A-14 Certificates on a Distribution
Date exceed the aggregate amount of principal distribution
requests for such Class which have been received on or
before the applicable Record Date, as provided in Section
4.07(a) above, additional Class I-A-14 Certificates will be
selected to receive mandatory principal distributions in
lots equal to $1,000 in accordance with the then-applicable
Random Lot procedures of DTC, and the then-applicable
procedures of the DTC Participants and Indirect DTC
Participants representing the Holders (which procedures may
or may not be by random lot).  The Trustee shall notify DTC
of the aggregate amount of the mandatory principal
distribution to be made on the next Distribution Date.  DTC
shall then allocate such aggregate amount among the DTC
Participants on a Random Lot basis.  Each DTC Participant
and, in turn, each Indirect DTC Participant will then
select, in accordance with its own procedures, Class I-A-14
Certificates from among those held in its accounts to
receive mandatory principal distributions, such that the
total amount of principal distributed to the Class I-A-14
Certificates so selected is equal to the aggregate amount of
such mandatory distributions allocated to such DTC
Participant by DTC and to such Indirect DTC Participant by
its related DTC Participant, as the case may be.  DTC
Participants and Indirect DTC Participants that hold Class I-
A-14 Certificates selected for mandatory principal
distributions are required to provide notice of such
mandatory distributions to the affected Holders.  The Master
Servicer shall notify the Trustee in writing of the amount
of principal distributions to be made on each Distribution
Date in a timely manner such that the Trustee may fulfill
its obligations under the Depositary Agreement.

(e)  Notwithstanding any provisions herein to the contrary,
on each Distribution Date on and after the earlier of (i)
the Group I Credit Support Depletion Date and (ii) the date
<PAGE>



<PAGE> 193

on which any loss is allocated to the Class I-A-14
Certificates by Pro Rata Allocation,, distributions in
reduction of the Class Principal Balance of such Class will
be made pro rata among the Holders of the Certificates of
such Class and will not be made in integral multiples of
$1,000 nor pursuant to requests for distribution as
permitted by Section 4.07(a) or by mandatory distributions
as provided for by Section 4.07(d).
     In the event that Definitive Certificates representing
the Class I-A-14 Certificates are issued pursuant to Section
5.09, an amendment to this Agreement, which may be approved
without the consent of any Certificateholders, shall
establish procedures relating to the manner in which
distributions in reduction of the Class I-A-14 Principal
Balance are to be made; provided that such procedures shall
be consistent, to the extent practicable and customary for
certificates similar to the Class I-A-14 Certificates, with
the provisions of this Section 4.07.

     Section 5.01.  The Certificates.

     (a)  The Certificates shall be substantially in the
forms set forth in Exhibit A and B with the additional
insertion from Exhibit H attached hereto, and shall be
executed by the Trustee, authenticated by the Trustee (or
any duly appointed Authenticating Agent) and delivered to or
upon the order of the Company upon receipt by the Trustee of
the documents specified in Section 2.01. The Certificates
shall be issuable in Authorized Denominations evidencing
Percentage Interests. Certificates shall be executed by
manual or facsimile signature on behalf of the Trustee by
authorized officers of the Trustee. Certificates bearing the
manual or facsimile signatures of individuals who were at
the time of execution the proper officers of the Trustee
shall bind the Trustee, notwithstanding that such
individuals or any of them have ceased to hold such offices
prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of
such Certificates. No Certificate shall be entitled to any
benefit under this Agreement, or be valid for any purpose,
unless there appears on such Certificate a certificate of
authentication substantially in the form provided for herein
executed by the Trustee or any Authenticating Agent by
manual signature, and such certificate upon any Certificate
shall be conclusive evidence, and the only evidence, that
such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their
authentication.

     (c)  Restrictions on Transfers of the Residual

this Section 5.01(c).

          (i)  Each Person who has or who acquires any
     Ownership Interest in a Residual Certificate shall be
     deemed by the acceptance or acquisition of such
     Ownership Interest to have agreed to be bound by the
     following provisions and to have irrevocably authorized
     the Trustee or its designee under clause (iii)(A) below
     to deliver payments to a Person other than such Person
     and to negotiate the terms of any mandatory sale under
     clause (iii)(B) below and to execute all instruments of
     transfer and to do all other things necessary in
     connection with any such sale. The rights of each
     Person acquiring any Ownership Interest in a Residual
     Certificate are expressly subject to the following
     provisions:
     
               (A)  Each Person holding or acquiring any
          Ownership Interest in a Residual Certificate shall
          be a Permitted Transferee and shall promptly
          notify the Trustee of any change or impending
          change in its status as a Permitted Transferee.
          
               (B)  In connection with any proposed Transfer
          of any Ownership Interest in a Residual
          Certificate to a U.S. Person, the Trustee shall
          require delivery to it, and shall not register the
          Transfer of any Residual Certificate until its
          receipt of (1) an affidavit and agreement (a
<PAGE>



<PAGE> 195

          "Transferee Affidavit and Agreement") attached
          hereto as Exhibit J from the proposed Transferee,
          in form and substance satisfactory to the Company,
          representing and warranting, among other things,
          that it is not a Non-U.S. Person, that such
          transferee is a Permitted Transferee, that it is
          not acquiring its Ownership Interest in the
          Residual Certificate that is the subject of the
          proposed Transfer as a nominee, trustee or agent
          for any Person who is not a Permitted Transferee,
          that for so long as it retains its Ownership
          Interest in a Residual Certificate, it will
          endeavor to remain a Permitted Transferee, and
          that it has reviewed the provisions of this
          Section 5.01(c) and agrees to be bound by them,
          and (2) a certificate, attached hereto as Exhibit
          I, from the Holder wishing to transfer the
          Residual Certificate, in form and substance
          satisfactory to the Company, representing and
          warranting, among other things, that no purpose of
          the proposed Transfer is to allow such Holder to
          impede the assessment or collection of tax.
          
               (C)  Notwithstanding the delivery of a
          Transferee Affidavit and Agreement by a proposed
          Transferee under clause (B) above, if the Trustee
          has actual knowledge that the proposed Transferee
          is not a Permitted Transferee, no Transfer of an
          Ownership Interest in a Residual Certificate to
          such proposed Transferee shall be effected.
          
               (D)  Each Person holding or acquiring any
          Ownership Interest in a Residual Certificate
          agrees by holding or acquiring such Ownership
          Interest (i) to require a Transferee Affidavit and
          Agreement from any other Person to whom such
          Person attempts to transfer its Ownership Interest
          and to provide a certificate to the Trustee in the
          form attached hereto as Exhibit J; (ii) to obtain
          the express written consent of the Company prior
          to any transfer of such Ownership Interest, which
          consent may be withheld in the Company's sole
          discretion; and (iii) to provide a certificate to
          the Trustee in the form attached hereto as Exhibit
          I.
          
          (ii) The Trustee shall register the Transfer of
     any Residual Certificate only if it shall have received
     the Transferee Affidavit and Agreement, a certificate
     of the Holder requesting such transfer in the form
     attached hereto as Exhibit J and all of such other
     documents as shall have been reasonably required by the
<PAGE>



<PAGE> 196

     Trustee as a condition to such registration.
     
          (iii)     (A)  If any "disqualified organization"
     (as defined in Section 860E(e)(5) of the Code) shall
     become a holder of a Residual Certificate, then the
     last preceding Permitted Transferee shall be restored,
     to the extent permitted by law, to all rights and
     obligations as Holder thereof retroactive to the date
     of registration of such Transfer of such Residual
     Certificate. If any Non-U.S. Person shall become a
     holder of a Residual Certificate, then the last
     preceding holder which is a U.S. Person shall be
     restored, to the extent permitted by law, to all rights
     and obligations as Holder thereof retroactive to the
     date of registration of the Transfer to such Non-U.S.
     Person of such Residual Certificate. If a transfer of a
     Residual Certificate is disregarded pursuant to the
     provisions of Treasury Regulations Section 1.860E-1 or
     Section 1.860G-3, then the last preceding Permitted
     Transferee shall be restored, to the extent permitted
     by law, to all rights and obligations as Holder thereof
     retroactive to the date of registration of such
     Transfer of such Residual Certificate. The Trustee
     shall be under no liability to any Person for any
     registration of Transfer of a Residual Certificate that
     is in fact not permitted by this Section 5.01(c) or for
     making any payments due on such Certificate to the
     holder thereof or for taking any other action with
     respect to such holder under the provisions of this
     Agreement.
     
               (B)  If any purported Transferee shall become
          a Holder of a Residual Certificate in violation of
          the restrictions in this Section 5.01(c) and to
          the extent that the retroactive restoration of the
          rights of the Holder of such Residual Certificate
          as described in clause (iii)(A) above shall be
          invalid, illegal or unenforceable, then the
          Company shall have the right, without notice to
          the Holder or any prior Holder of such Residual
          Certificate, to sell such Residual Certificate to
          a purchaser selected by the Company on such terms
          as the Company may choose. Such purported
          Transferee shall promptly endorse and deliver each
          Residual Certificate in accordance with the
          instructions of the Company. Such purchaser may be
          the Company itself or any affiliate of the
          Company. The proceeds of such sale, net of the
          commissions (which may include commissions payable
          to the Company or its affiliates), expenses and
          taxes due, if any, shall be remitted by the
          Company to such purported Transferee. The terms
<PAGE>



<PAGE> 197

          and conditions of any sale under this clause
          (iii)(B) shall be determined in the sole
          discretion of the Company, and the Company shall
          not be liable to any Person having an Ownership
          Interest in a Residual Certificate as a result of
          its exercise of such discretion.
          
          (iv) The Company, on behalf of the Trustee, shall
     make available, upon written request from the Trustee,
     all information necessary to compute any tax imposed
     (A) as a result of the Transfer of an Ownership
     Interest in a Residual Certificate to any Person who is
     not a Permitted Transferee, including the information
     regarding "excess inclusions" of such Residual
     Certificates required to be provided to the Internal
     Revenue Service and certain Persons as described in
     Treasury Regulation Section 1.860D-1(b)(5), and (B) as
     a result of any regulated investment company, real
     estate investment trust, common trust fund,
     partnership, trust, estate or organizations described
     in Section 1381 of the Code having as among its record
     holders at any time any Person who is not a Permitted
     Transferee. Reasonable compensation for providing such
     information may be required by the Company from such
     Person.
     
          (v)  The provisions of this Section 5.01 set forth
     prior to this Section (v) may be modified, added to or
     eliminated by the Company and the Trustee, provided
     that there shall have been delivered to the Trustee the
     following:
     
               (A)  written notification from each Rating
          Agencies to the effect that the modification,
          addition to or elimination of such provisions will
          not cause such Rating Agencies to downgrade its
          then-current Ratings of the Certificates
          (determined in the case of the Insured
          Certificates, without giving effect to the
          Certificate Insurance Policy); and
          
               (B)  an Opinion of Counsel, in form and
          substance satisfactory to the Company (as
          evidenced by a certificate of the Company), to the
          effect that such modification, addition to or
          absence of such provisions will not cause REMIC I,
          REMIC II and REMIC III to cease to qualify as a
          REMIC and will not create a risk that (1) REMIC I,
          REMIC II and REMIC III may be subject to an entity-
          level tax caused by the Transfer of any Residual
          Certificate to a Person which is not a Permitted
          Transferee or (2) a Certificateholder or another
<PAGE>



<PAGE> 198

          Person will be subject to a REMIC-related tax
          caused by the Transfer of a Residual Certificate
          to a Person which is not a Permitted Transferee.
          
          (vi) The following legend shall appear on all
     Residual Certificates:
     
     ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS
     CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED TRANSFEREE
     PROVIDES A TRANSFER AFFIDAVIT TO THE COMPANY AND THE
     TRUSTEE THAT (1) SUCH TRANSFEREE IS NOT EITHER (A) THE
     UNITED STATES, ANY STATE OR POLITICAL SUBDIVISION
     THEREOF, ANY FOREIGN GOVERNMENT, ANY INTERNATIONAL
     ORGANIZATION, OR ANY AGENCY OR INSTRUMENTALITY OF ANY
     OF THE FOREGOING, (B) ANY ORGANIZATION (OTHER THAN A
     COOPERATIVE DESCRIBED IN SECTION 521 OF THE CODE) WHICH
     IS EXEMPT FROM THE TAX IMPOSED BY CHAPTER 1 OF THE CODE
     UNLESS SUCH ORGANIZATION IS SUBJECT TO THE TAX IMPOSED
     BY SECTION 511 OF THE CODE, (C) ANY ORGANIZATION
     DESCRIBED IN SECTION 1381(a)(2)(C) OF THE CODE (ANY
     SUCH PERSON DESCRIBED IN THE FOREGOING CLAUSES (A),
     (B), OR (C) BEING HEREINAFTER REFERRED TO AS A
     "DISQUALIFIED ORGANIZATION"), OR (D) AN AGENT OF A
     DISQUALIFIED ORGANIZATION AND (2) NO PURPOSE OF SUCH
     TRANSFER IS TO ENABLE THE TRANSFEROR TO IMPEDE THE
     ASSESSMENT OR COLLECTION OF TAX. SUCH AFFIDAVIT SHALL
     INCLUDE CERTAIN REPRESENTATIONS AS TO THE FINANCIAL
     CONDITION OF THE PROPOSED TRANSFEREE. NOTWITHSTANDING
     THE REGISTRATION IN THE CERTIFICATE REGISTER OF ANY
     TRANSFER, SALE OR OTHER DISPOSITION OF THIS CLASS [R-1]
     [R-2] [R-3] CERTIFICATE TO A DISQUALIFIED ORGANIZATION
     OR AN AGENT OF A DISQUALIFIED ORGANIZATION, SUCH
     REGISTRATION SHALL BE DEEMED TO BE OF NO LEGAL FORCE OR
     EFFECT WHATSOEVER AND SUCH PERSON SHALL NOT BE DEEMED
     TO BE A CERTIFICATEHOLDER FOR ANY PURPOSE HEREUNDER,
     INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF
     DISTRIBUTIONS ON THIS CERTIFICATE. EACH HOLDER OF THE
     CLASS [R-1][R-2] [R-3]CERTIFICATE BY ACCEPTANCE OF THIS
     CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE
     PROVISIONS OF THIS PARAGRAPH.
     
          (vii)     The Tax Matters Person for each of REMIC
     I, REMIC II and REMIC III, while not a Disqualified
     Organization, shall be the tax matters person for the
     related REMIC within the meaning of Section 6231(a)(7)
     of the Code and Treasury Regulation Section 1.860F-
     4(d).
     
     (d)  In the case of any Class B or Residual
Certificates presented for registration in the name of any
Person, the Trustee shall require either (i) an Opinion of
Counsel acceptable to and in form and substance satisfactory
<PAGE>



<PAGE> 199

to the Trustee and the Company to the effect that the
purchase or holding of a Class B or Residual Certificate is
permissible under applicable law, will not constitute or
result in a non-exempt prohibited transaction under Section
406 of ERISA or Section 4975 of the Code, and will not
subject the Trustee, the Master Servicer or the Company to
any obligation or liability (including obligations or
liabilities under Section 406 of ERISA or Section 4975 of
the Code) in addition to those undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the
Trustee, the Master Servicer or the Company or (ii) only in
the case of a Class B Certificate, an officer's certificate
substantially in the form of Exhibit N attached hereto
acceptable to and in form and substance satisfactory to the
Trustee and the Company, which officer's certificate shall
not be an expense of the Trustee, the Master Servicer or the
Company.

     (e)  No transfer, sale, pledge or other disposition of
a Junior Subordinate Certificate shall be made unless such
transfer, sale, pledge or other disposition is made in
accordance with this Section 5.01(e) or Section 5.01(f);
provided that any transfer, sale, pledge or other
disposition of a Junior Subordinate Certificate shall be
exempt from the requirements of this Section 5.01(e) and
Section 5.01(f) if each of the Certificateholder desiring to
effect such transfer and such Certificateholder's transferee
are among the following: (i) DLJ Mortgage Capital, Inc.,
(ii) Donaldson, Lufkin & Jenrette Securities Corporation and
(iii) DLJ Mortgage Acceptance Corp. Each Person who, at any
time, acquires any ownership interest in any Junior
Subordinate Certificate shall be deemed by the acceptance or
acquisition of such ownership interest to have agreed to be
bound by the following provisions of this Section 5.01(e)
and Section 5.01(f), as applicable. No transfer of a Junior
Subordinate Certificate shall be deemed to be made in
accordance with this Section 5.01(e) unless such transfer is
made pursuant to an effective registration statement under
the Securities Act or unless the Trustee is provided with
the certificates and an Opinion of Counsel, if required, on
which the Trustee may conclusively rely, which establishes
or establish to the Trustee's satisfaction that such
transfer is exempt from the registration requirements under
the Securities Act, as follows:  In the event that a
transfer is to be made in reliance upon an exemption from
the Securities Act, the Trustee shall require, in order to
assure compliance with the Securities Act, that the
Certificateholder desiring to effect such transfer certify
to the Trustee in writing, in substantially the form
attached hereto as Exhibit F, the facts surrounding the
transfer, with such modifications to such Exhibit F as may
be appropriate to reflect the actual facts of the proposed
<PAGE>



<PAGE> 200

transfer, and that the Certificateholder's proposed
transferee certify to the Trustee in writing, in
substantially the form attached hereto as Exhibit G, the
facts surrounding the transfer, with such modifications to
such Exhibit G as may be appropriate to reflect the actual
facts of the proposed transfer. If such certificate of the
proposed transferee does not contain substantially the
substance of Exhibit G, the Trustee shall require an Opinion
of Counsel satisfactory to it that such transfer may be made
without registration, which Opinion of Counsel shall not be
obtained at the expense of the Trustee, the REMIC I Trust
Fund, the REMIC II Trust Fund, the REMIC III Trust Fund or
the Company. Such Opinion of Counsel shall allow for the
forwarding, and the Trustee shall forward, a copy thereof to
the Rating Agencies. Notwithstanding the foregoing, any
Junior Subordinate Certificate may be transferred, sold,
pledged or otherwise disposed of in accordance with the
requirements set forth in Section 5.01(f).

     (f)  To effectuate a Certificate transfer of a Junior
Subordinate Certificate in accordance with this Section
5.01(f), the proposed transferee of such Certificate must
provide the Trustee and the Company with an investment
letter substantially in the form of Exhibit L attached
hereto, which investment letter shall not be an expense of
the Trustee or the Company, and which investment letter
states that, among other things, such transferee (i) is a
"qualified institutional buyer" as defined under Rule 144A,
acting for its own account or the accounts of other
"qualified institutional buyers" as defined under Rule 144A,
and (ii) is aware that the proposed transferor intends to
rely on the exemption from registration requirements under
the Securities Act provided by Rule 144A. Notwithstanding
the foregoing, the proposed transferee of such Certificate
shall not be required to provide the Trustee or the Company
with Annex 1 or Annex 2 to the form of Exhibit L attached
hereto if the Company so consents prior to each such
transfer. Such transfers shall be deemed to have complied
with the requirements of this Section 5.01(f). The Holder of
a Certificate desiring to effect such transfer does hereby
agree to indemnify the Trustee, the Company, and the
Certificate Registrar against any liability that may result
if transfer is not made in accordance with this Agreement.

     Section 5.02.  Certificates Issuable in Classes;
Distributions of Principal and Interest; Authorized
Denominations. The aggregate principal amount of the
Certificates that may be authenticated and delivered under
this Agreement is limited to the aggregate Principal Balance
of the Mortgage Loans as of the Cut-Off Date, as specified
in the Preliminary Statement to this Agreement, except for
Certificates authenticated and delivered upon registration
<PAGE>



<PAGE> 201

of transfer of, or in exchange for, or in lieu of, other
Certificates pursuant to Section 5.03. Such aggregate
principal amount shall be allocated among one or more
Classes having designations, types of interests, initial per
annum Certificate Interest Rates, initial Class Principal
Balances and Final Maturity Dates as specified in the
Preliminary Statement to this Agreement. The aggregate
Percentage Interest of each Class of Certificates of which
the Class Principal Balance equals zero as of the Cut-Off
Date that may be authenticated and delivered under this
Agreement is limited to 100%. Certificates shall be issued
in Authorized Denominations.

Section 5.03.  Registration of Transfer and Exchange of
Certificates. The Trustee shall cause to be maintained at
one of its offices or at its designated agent, a Certificate
Register in which there shall be recorded the name and
address of each Certificateholder. Subject to such
reasonable rules and regulations as the Trustee may
prescribe, the Certificate Register shall be amended from
time to time by the Trustee or its agent to reflect notice
of any changes received by the Trustee or its agent pursuant
to Section 10.06. The Trustee hereby appoints itself as the
initial Certificate Registrar.

     Upon surrender for registration of transfer of any
Certificate to the Trustee at the Corporate Trust Office of
the Trustee or at the office of State Street Bank and Trust
Company, N.A., 61 Broadway, New York, New York 10006,
Attention: Corporate Trust Window, or such other address or
agency as may hereafter be provided to the Master Servicer
in writing by the Trustee, the Trustee shall execute, and
the Trustee or any Authenticating Agent shall authenticate
and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of Authorized
Denominations of like Percentage Interest. At the option of
the Certificateholders, Certificates may be exchanged for
other Certificates in Authorized Denominations of like
Percentage Interest, upon surrender of the Certificates to
be exchanged at any such office or agency. Whenever any
Certificates are so surrendered for exchange, the Trustee
shall execute, and the Trustee, or any Authenticating Agent,
shall authenticate and deliver, the Certificates which the
Certificateholder making the exchange is entitled to
receive. Every Certificate presented or surrendered for
transfer shall (if so required by the Trustee or any
Authenticating Agent) be duly endorsed by, or be accompanied
by a written instrument of transfer in form satisfactory to
the Trustee or any Authenticating Agent and duly executed
by, the Holder thereof or such Holder's attorney duly
authorized in writing.

     A reasonable service charge may be made for any such
exchange or transfer of Certificates, and the Trustee may
require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with
any exchange or transfer of Certificates.

     All Certificates surrendered for exchange or transfer
shall be cancelled by the Trustee or any Authenticating
Agent.

     Section 5.04.  Mutilated, Destroyed, Lost or Stolen
Certificates. If (i) any mutilated Certificate is
surrendered to the Trustee or any Authenticating Agent, or
(ii) the Trustee or any Authenticating Agent receives
evidence to their satisfaction of the destruction, loss or
theft of any Certificate, and there is delivered to the
Trustee or any Authenticating Agent (and with respect to the
Insured Certificates, the Certificate Insurer) such security
or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Trustee or
any Authenticating Agent that such Certificate has been
acquired by a bona fide purchaser, the Trustee shall execute
and the Trustee or any 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 Percentage Interest. Upon the issuance
of any new Certificate under this Section 5.04, the Trustee
or any Authenticating Agent may require the payment of a sum
sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee or
any Authenticating Agent) connected therewith. Any
replacement Certificate issued pursuant to this Section 5.04
shall constitute complete and indefeasible evidence of
ownership in the REMIC III Trust Fund (or with respect to
the Class R-1 and Class R-2 Certificates, the residual
ownership interests in the REMIC I Trust Fund and REMIC II
Trust Fund, respectively) as if originally issued, whether
or not the lost or stolen Certificate shall be found at any
time.

     Section 5.05.  Persons Deemed Owners. The Company, the
Master Servicer, the Trustee, the Certificate Insurer (with
respect to the Insured Certificates) and any agent of any of
them may treat the Person in whose name any Certificate is
registered as the owner of such Certificate for the purpose
of receiving distributions pursuant to Section 4.01, Section
4.04 and Section 4.06 and for all other purposes whatsoever,
and neither the Company, the Master Servicer, the Trustee,
the Certificate Registrar nor any agent of the Company, the
Master Servicer or the Trustee shall be affected by notice
to the contrary.

     Section 5.06.  Temporary Certificates. Upon the initial
issuance of the Certificates, the Trustee may execute, and
the Trustee or any Authenticating Agent shall authenticate
and deliver, temporary Certificates which are printed,
lithographed, typewritten or otherwise produced, in any
Authorized Denomination, of the tenor of the definitive
Certificates in lieu of which they are issued and with such
variations in form from the forms of the Certificates set
forth as Exhibits A, B, C and H hereto as the Trustee's
officers executing such Certificates may determine, as
evidenced by their execution of the Certificates.
Notwithstanding the foregoing, the Certificates may remain
in the form of temporary Certificates.

     If temporary Certificates are issued, the Trustee shall
cause definitive Certificates to be prepared within ten
Business Days of the Closing Date or as soon as practicable
thereafter. After preparation of definitive Certificates,
the temporary Certificates shall be exchangeable for
definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee to be
maintained as provided in Section 5.10 hereof, without
charge to the holder. Any tax or governmental charge that
may be imposed in connection with any such exchange shall be
borne by the Master Servicer. Upon surrender for
cancellation of any one or more temporary Certificates, the
Trustee shall execute and the Trustee or any Authenticating
Agent shall authenticate and deliver in exchange therefor a
like principal amount of definitive Certificates of
Authorized Denominations. Until so exchanged, the temporary
Certificates shall in all respects be entitled to the same
benefits under this Agreement as definitive Certificates.

     Section 5.07.  Book-Entry for Book-Entry Certificates.
Notwithstanding the foregoing, the Book-Entry Certificates,
upon original issuance, shall be issued in the form of one
or more typewritten Certificates of Authorized Denomination
representing the Book-Entry Certificates, to be delivered to
DTC, the initial Clearing Agency, by, or on behalf of, the
Company. The Book-Entry Certificates shall initially be
registered on the Certificate Register in the name of Cede &
Co., the nominee of DTC, as the initial Clearing Agency, and
no Beneficial Holder shall receive a definitive certificate
representing such Beneficial Holder's interest in any Class
of Book-Entry Certificate, except as provided above and in
Section 5.09. Each Book-Entry Certificate shall bear the
following legend:

     Unless this Certificate is presented by an
     authorized representative of The Depository Trust
     Company, a New York corporation ("DTC"), to the
     Trustee or its agent for registration of transfer,
<PAGE>



<PAGE> 204

     exchange, or payment, and any Certificate issued
     is registered in the name of Cede & Co. or such
     other name as is requested by an authorized
     representative of DTC (and any payment is made to
     Cede & Co. or to such other entity as is requested
     by an authorized representative of DTC), ANY
     TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
     OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
     as the registered owner hereof, Cede & Co., has an
     interest herein.
     
Unless and until definitive, fully registered Book-Entry
Certificates (the "Definitive Certificates") have been
issued to the Beneficial Holders pursuant to Section 5.09:

          (a)  the provisions of this Section 5.07 shall be
     in full force and effect with respect to the Book-Entry
     Certificates;
     
          (b)  the Master Servicer and the Trustee may deal
     with the Clearing Agency for all purposes with respect
     to the Book-Entry Certificates (including the making of
     distributions on the Book-Entry Certificates) as the
     sole Certificateholder;
     
          (c)  to the extent that the provisions of this
     Section 5.07 conflict with any other provisions of this
     Agreement, the provisions of this Section 5.07 shall
     control; and
     
          (d)  the rights of the Beneficial Holders shall be
     exercised only through the Clearing Agency and the DTC
     Participants and shall be limited to those established
     by law and agreements between such Beneficial Holders
     and the Clearing Agency and/or the DTC Participants.
     Pursuant to the Depositary Agreement, unless and until
     Definitive Certificates are issued pursuant to Section
     5.09, the initial Clearing Agency will make book-entry
     transfers among the DTC Participants and receive and
     transmit distributions of principal and interest on the
     related Class of Book-Entry Certificates to such DTC
     Participants.
     
     For purposes of any provision of this Agreement
requiring or permitting actions with the consent of, or at
the direction of, Holders of Book-Entry Certificates
evidencing a specified Percentage Interest, such direction
or consent may be given by the Clearing Agency at the
direction of Beneficial Holders owning Book-Entry
Certificates evidencing the requisite Percentage Interest
represented by the Book-Entry Certificates. The Clearing
Agency may take conflicting actions with respect to the Book-
<PAGE>



<PAGE> 205

Entry Certificates to the extent that such actions are taken
on behalf of the Beneficial Holders.

     Section 5.08.  Notices to Clearing Agency. Whenever notice
or other communication to the Certificateholders is required
under this Agreement, unless and until Definitive
Certificates shall have been issued to the related
Certificateholders pursuant to Section 5.09, the Trustee
shall give all such notices and communications specified
herein to be given to Holders of the Book-Entry Certificates
to the Clearing Agency which shall give such notices and
communications to the related DTC Participants in accordance
with its applicable rules, regulations and procedures.

     Section 5.09.  Definitive Certificates. If (a) the Master
Servicer notifies the Trustee in writing that the Clearing
Agency is no longer willing or able to discharge properly
its responsibilities under the Depositary Agreement with
respect to the Book-Entry Certificates and the Trustee or
the Master Servicer is unable to locate a qualified
successor, (b) the Master Servicer, at its option, advises
the Trustee in writing that it elects to terminate the book-
entry system with respect to the Book-Entry Certificates
through the Clearing Agency or (c) after the occurrence of
an Event of Default, Certificateholders holding Book-Entry
Certificates evidencing Percentage Interests aggregating not
less than 66% of the aggregate Class Principal Balance of
such Certificates advise the Trustee and the Clearing Agency
through DTC Participants in writing that the continuation of
a book-entry system with respect to the Book-Entry
Certificates through the Clearing Agency is no longer in the
best interests of the Certificateholders with respect to
such Certificates, the Trustee shall notify all
Certificateholders of Book-Entry Certificates of the
occurrence of any such event and of the availability of
Definitive Certificates. Upon surrender to the Trustee of
the Book-Entry Certificates by the Clearing Agency,
accompanied by registration instructions from the Clearing
Agency for registration, the Trustee shall execute and the
Trustee or any Authenticating Agent shall authenticate and
deliver the Definitive Certificates. Neither the Company,
the Master Servicer nor the 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
for all of the Certificates all references herein to
obligations imposed upon or to be performed by the Clearing
Agency shall be deemed to be imposed upon and performed by
the Trustee, to the extent applicable with respect to such
Definitive Certificates, and the Trustee shall recognize the
Holders of Definitive Certificates as Certificateholders
hereunder.

     Section 6.01.  Liability of the Company and the Master
Servicer. The Company and the Master Servicer shall be
liable in accordance herewith only to the extent of the
obligations specifically imposed upon and undertaken by the
Company or the Master Servicer, as applicable, herein..

successor of the Company or the Master Servicer hereunder,
without the execution or filing of any paper or any further
act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

     Section 6.03.  Limitation on Liability of the Company, the
Master Servicer and Others. Neither the Company nor the
Master Servicer nor any of the directors, officers,
employees or agents of the Company or the Master Servicer
shall be under any liability to the REMIC I, REMIC II or
REMIC III Trust Fund or the Certificateholders for any
action taken by such Person or by a Servicer or for such
Person's or Servicer's refraining from the taking of any
action in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision
shall not protect the Company, the Master Servicer or any
such Person against any liability which would otherwise be
imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of
reckless disregard of duties and obligations hereunder. The
Company, the Master Servicer and any director, officer,

held harmless against any loss, liability or expense
incurred in connection with any legal action relating to
this Agreement or the Certificates, other than any loss,
liability or expense relating to any Mortgage Loan (other
than as otherwise permitted in this Agreement) or incurred
by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties hereunder or by
reason of reckless disregard of obligations and duties
hereunder. The Company and the Master Servicer shall not be
under any obligation to appear in, prosecute or defend any
legal action which is not incidental to its duties to
service the Mortgage Loans in accordance with this Agreement
and which in its opinion may involve it in any expense or
liability; provided, however, that the Company or the Master
Servicer may in its discretion undertake any such action
which it may deem necessary or desirable with respect to the
Mortgage Loans, this Agreement, the Certificates or the
rights and duties of the parties hereto and the interests of
the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability
resulting therefrom shall be expenses, costs and liabilities
of the Trust Fund and the Company and the Master Servicer
shall be entitled to be reimbursed therefor out of the
Certificate Account, as provided by Section 3.05.

     Section 6.04.  The Company and the Master Servicer not to

and duties (including, without limitation, its obligations
and duties as initial Master Servicer) hereby imposed on it
except upon determination that its duties hereunder are no

Master Servicer shall not resign from the obligations and
duties hereby imposed on it except upon determination that
its duties hereunder are no longer permissible under
applicable law. Any such determination permitting the
resignation of the Company or any successor Master Servicer
shall be evidenced by an Opinion of Counsel to such effect
delivered to the Trustee. No such resignation shall become
effective until the Trustee or a successor Master Servicer
shall have assumed the Master Servicer's responsibilities
and obligations in accordance with Section 7.02 hereof.

          If the Company is no longer acting as Master
Servicer, then the successor Master Servicer shall give
prompt written notice to the Company of any information
received by such successor Master Servicer which affects or
relates to an ongoing obligation or right of the Company

statements for PNC Mortgage Securities Corp. appearing in
the audited financial statements of PNC Bank Corp.) and such
other information as it possesses, and which it is not
prohibited by law or, to the extent applicable, binding
obligations to third parties with respect to confidentiality
from disclosing, regarding its business, affairs, property
and condition, financial or otherwise.

     Section 7.01.  Events of Default. (a) In case one or more of
the following Events of Default by the Master Servicer or by
a successor Master Servicer shall occur and be continuing,
that is to say:

            (i)     Any failure by the Master Servicer to
     deposit into the Certificate Account any payment
     required to be deposited therein by the Master Servicer
     under the terms of this Agreement which continues
     unremedied for a period of ten days after the date upon
     which written notice of such failure, requiring the
     same to be remedied, shall have been given to the
     Master Servicer by the Trustee or to the Master
     Servicer and the Trustee by the Holders of Certificates
     evidencing Percentage Interests aggregating not less
     than 25% of the REMIC III Trust Fund; or

           (ii)     Failure on the part of the Master
     Servicer duly to observe or perform in any material
     respect any other of the covenants or agreements on the
     part of the Master Servicer contained in the
     Certificates or in this Agreement which continues
     unremedied for a period of 60 days after the date on
     which written notice of such failure, requiring the
     same to be remedied, shall have been given to the
     Master Servicer by the Trustee, or to the Master
     Servicer and the Trustee by the Holders of Certificates
     evidencing Percentage Interests aggregating not less
     than 25% of the REMIC III Trust Fund; or

<PAGE>



<PAGE> 209

          (iii)     A decree or order of a court or agency
     or supervisory authority having jurisdiction in the
     premises for the appointment of a trustee in
     bankruptcy, conservator or receiver or liquidator in
     any bankruptcy, insolvency, readjustment of debt,
     marshalling of assets and liabilities or similar
     proceedings, or for the winding-up or liquidation of
     its affairs, shall have been entered against the Master
     Servicer and such decree or order shall have remained
     in force undischarged or unstayed for a period of 60
     days; or

           (iv)     The Master Servicer shall consent to the
     appointment of a trustee in bankruptcy, conservator or
     receiver or liquidator in any bankruptcy, insolvency,
     readjustment of debt, marshalling of assets and
     liabilities or similar proceedings of or relating to
     the Master Servicer or of or relating to all or
     substantially all of its property; or

            (v)     The Master Servicer shall admit in
     writing its inability to pay its debts generally as
     they become due, file a petition to take advantage of
     any applicable bankruptcy, insolvency or reorganization
     statute, make an assignment for the benefit of its
     creditors, or voluntarily suspend payment of its
     obligations; or

           (vi)     Any failure of the Master Servicer to
     make any Monthly P&I Advance (other than a
     Nonrecoverable Advance) which continues unremedied at
     the opening of business on the Distribution Date in
     respect of which such Monthly P&I Advance was to have
     been made;

then, and in each and every such case, so long as an Event
of Default shall not have been remedied, either the Trustee,
or the Holders of Certificates evidencing Percentage
Interests aggregating not less than 25% of the REMIC III
Trust Fund, by notice in writing to the Company and the
Master Servicer (and to the Trustee if given by the
Certificateholders, in which case such notice shall set
forth evidence reasonably satisfactory to the Trustee that
such Event of Default has occurred and shall not have been
remedied) may terminate all of the rights (other than its
right to reimbursement for advances) and obligations of the
Master Servicer, including its right to the Master Servicing
Fee, under this Agreement and in and to the Mortgage Loans
and the proceeds thereof, if any. Such determination shall
be final and binding. On or after the receipt by the Master
Servicer of such written notice, all authority and power of
the Master Servicer under this Agreement, whether with
<PAGE>



<PAGE> 210

respect to the Certificates or the Mortgage Loans or
otherwise, shall pass to and be vested in the Trustee
pursuant to and under this Section 7.01; and, without
limitation, the Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as
attorney-in-fact or otherwise, any and all documents and
other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of
such notice of termination, whether to complete the transfer
and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees
to cooperate with the Trustee in effecting the termination
of the Master Servicer's responsibilities and rights
hereunder, including, without limitation, the transfer to
the Trustee for administration by it of all cash amounts
which shall at the time be credited by the Master Servicer
to the Certificate Account or thereafter be received with
respect to the Mortgage Loans.

          Notwithstanding the foregoing, if an Event of
Default described in clause (vi) of this Section 7.01(a)
shall occur, the Trustee shall, by notice in writing to the
Master Servicer, which may be delivered by telecopy,
immediately suspend all of the rights and obligations of the
Master Servicer thereafter arising under this Agreement, but
without prejudice to any rights it may have as a
Certificateholder or to reimbursement of Monthly P&I
Advances and other advances of its own funds, and the
Trustee shall act as provided in Section 7.02 to carry out
the duties of the Master Servicer, including the obligation
to make any Monthly P&I Advance the nonpayment of which was
an Event of Default described in clause (vi) of this
Section 7.01(a). Any such action taken by the Trustee must
be prior to the distribution on the relevant Distribution
Date. If the Master Servicer shall within two Business Days
following such suspension remit to the Trustee the amount of
any Monthly P&I Advance the nonpayment of which by the
Master Servicer was an Event of Default described in
clause (vi) of this Section 7.01(a), the Trustee shall
permit the Master Servicer to resume its rights and
obligations as Master Servicer hereunder. The Master
Servicer agrees that it will reimburse the Trustee for
actual, necessary and reasonable costs incurred by the
Trustee because of action taken pursuant to clause (vi) of
this Section 7.01(a). The Master Servicer agrees that if an
Event of Default as described in clause (vi) of this Section
7.01(a) shall occur more than two times in any twelve month
period, the Trustee shall be under no obligation to permit
the Master Servicer to resume its rights and obligations as
Master Servicer hereunder.

     (b)  In case one or more of the following Events of
<PAGE>



<PAGE> 211

Default by the Company shall occur and be continuing, that
is to say:

            (i)      Failure on the part of the Company duly
     to observe or perform in any material respect any of
     the covenants or agreements on the part of the Company
     contained in the Certificates or in this Agreement
     which continues unremedied for a period of 60 days
     after the date on which written notice of such failure,
     requiring the same to be remedied, shall have been
     given to the Company by the Trustee, or to the Company
     and the Trustee by the Holders of Certificates
     evidencing Percentage Interests aggregating not less
     than 25% of the REMIC III Trust Fund; or

           (ii)     A decree or order of a court or agency
     or supervisory authority having jurisdiction in the
     premises for the appointment of a trustee in
     bankruptcy, conservator or receiver or liquidator in
     any bankruptcy, insolvency, readjustment of debt,
     marshalling of assets and liabilities or similar
     proceedings, or for the winding-up or liquidation of
     its affairs, shall have been entered against the
     Company and such decree or order shall have remained in
     force undischarged or unstayed for a period of 60 days;
     or

          (iii)     The Company shall consent to the
     appointment of a trustee in bankruptcy, conservator or
     receiver or liquidator in any bankruptcy, insolvency,
     readjustment of debt, marshalling of assets and
     liabilities or similar proceedings of or relating to
     the Company or of or relating to all or substantially
     all of its property; or

           (iv)     The Company shall admit in writing its
     inability to pay its debts generally as they become
     due, file a petition to take advantage of any
     applicable bankruptcy, insolvency or reorganization
     statute, make an assignment for the benefit of
     creditors, or voluntarily suspend payment of its
     obligations;

then, and in each and every such case, so long as such Event
of Default shall not have been remedied, the Holders of
Certificates evidencing Percentage Interests aggregating not
less than 25% of the REMIC III Trust Fund, by notice in
writing to the Company and the Trustee, may direct the
Trustee in accordance with Section 10.03 to institute an
action, suit or proceeding in its own name as Trustee
hereunder to enforce the Company's obligations hereunder.

<PAGE>



<PAGE> 212

     (c)  In any circumstances in which this Agreement
states that Certificateholders owning Certificates
evidencing a certain percentage Percentage Interest in the
REMIC III Trust Fund may take certain action, such action
shall be taken by the Trustee, but only if the requisite
percentage of Certificateholders required under this
Agreement for taking like action or giving like instruction
to the Trustee under this Agreement shall have so directed
the Trustee in writing.

     Section 7.02.  Trustee to Act; Appointment of Successor. On
and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01, the Trustee shall be
the successor in all respects to the Master Servicer under
this Agreement and under the Selling and Servicing Contracts
with respect to the Mortgage Loans in the Mortgage Pool and
with respect to the transactions set forth or provided for
herein and shall have all the rights and powers and be
subject to all the responsibilities, duties and liabilities
relating thereto arising after the Master Servicer receives
such notice of termination placed on the Master Servicer by
the terms and provisions hereof and thereof, and shall have
the same limitations on liability herein granted to the
Master Servicer; provided, that the Trustee shall not under
any circumstances be responsible for any representations and
warranties or any Purchase Obligation of the Company or any
liability incurred by the Master Servicer at or prior to the
time the Master Servicer was terminated as Master Servicer
and the Trustee shall not be obligated to make a Monthly P&I
Advance if it is prohibited by law from so doing. As
compensation therefor, the Trustee shall be entitled to all
funds relating to the Mortgage Loans which the Master
Servicer would have been entitled to retain or to withdraw
from the Certificate Account if the Master Servicer had
continued to act hereunder, except for those amounts due to
the Master Servicer as reimbursement for advances previously
made or amounts previously expended and are otherwise
reimbursable hereunder. Notwithstanding the above, the
Trustee may, if it shall be unwilling to so act, or shall if
it is unable to so act, appoint, or petition a court of
competent jurisdiction to appoint, any established housing
and home finance institution having a net worth of not less
than $10,000,000 as the successor to the Master Servicer
hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of the Master
Servicer hereunder. Pending any such appointment, the
Trustee is obligated to act in such capacity. In connection
with such appointment and assumption, the Trustee may make
such arrangements for the compensation of such successor out
of payments on Mortgage Loans as it and such successor shall
agree; provided, however, that no such compensation shall,
together with the compensation to the Trustee, be in excess
<PAGE>



<PAGE> 213

of that permitted the Master Servicer hereunder. The Trustee
and such successor shall take such actions, consistent with
this Agreement, as shall be necessary to effectuate any such
succession.

     Section 7.03.  Notification to Certificateholders. Upon any
such termination or appointment of a successor to the Master
Servicer, the Trustee shall give prompt written notice
thereof to Certificateholders at their respective addresses
appearing in the Certificate Register.

     Section 8.01.  Duties of Trustee.

     (a)  The Trustee, prior to the occurrence of an Event
of Default and after the curing of all Events of Default
which may have occurred, undertakes to perform such duties
and only such duties as are specifically set forth in this
Agreement. In case an Event of Default has occurred (which
has not been cured or waived) the Trustee shall exercise
such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in its
exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

     (b)  The Trustee, upon receipt of all resolutions,
certificates, statements, opinions, reports, documents,
orders or other instruments furnished to the Trustee which
are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine
whether they are in the form required by this Agreement;
provided, however, that the Trustee shall not be responsible
for the accuracy or content of any such certificate,
statement, opinion, report, or other order or instrument
furnished by the Company or Master Servicer to the Trustee
pursuant to this Agreement.

     (c)  No provision of this Agreement shall be construed
to relieve the Trustee from liability for its own negligent
action, its own negligent failure to act or its own willful
misconduct; provided, however, that:

          (i)  Prior to the occurrence of an Event of
     Default and after the curing of all such Events of
     Default which may have occurred, the duties and
     obligations of the Trustee shall be determined solely
     by the express provisions of this Agreement,
     
          (ii) the Trustee shall not be liable except for
<PAGE>



<PAGE> 214

     the performance of such duties and obligations as are
     specifically set forth in this Agreement, no implied
     covenants or obligations shall be read into this
     Agreement against the Trustee, and, in the absence of
     bad faith on the part of the Trustee, the Trustee may
     conclusively rely, as to the truth of the statements
     and the correctness of the opinions expressed therein,
     upon any certificates or opinions furnished to the
     Trustee and conforming to the requirements of this
     Agreement; and
     
          (iii)     The Trustee shall not be personally
     liable with respect to any action taken or omitted to
     be taken by it in good faith in accordance with the
     direction of the Certificateholders holding
     Certificates which evidence Percentage Interests
     aggregating not less than 25% of the REMIC III Trust
     Fund relating to the time, method and place of
     conducting any proceeding for any remedy available to
     the Trustee, or relating to the exercise of any trust
     or power conferred upon the Trustee under this
     Agreement.
     
     (d)  Within ten days after the occurrence of any Event
of Default known to the Trustee, the Trustee shall transmit
by mail to the Rating Agencies notice of each Event of
Default. Within 90 days after the occurrence of any Event of
Default known to the Trustee, the Trustee shall transmit by
mail to all Certificateholders (with a copy to the Rating
Agencies) notice of each Event of Default, unless such Event
of Default shall have been cured or waived; provided,
however, the Trustee shall be protected in withholding such
notice if and so long as a Responsible Officer of the
Trustee in good faith determines that the withholding of
such notice is in the best interests of the
Certificateholders; and provided, further, that in the case
of any Event of Default of the character specified in
Section 7.01(i) and Section 7.01(ii) no such notice to
Certificateholders or to the Rating Agencies shall be given
until at least 30 days after the occurrence thereof.

     (e) Concurrently with the execution hereof, the Trustee
shall execute and deliver to the Certificate Insurer the
Insurance Agreement dated of even date herewith and shall
perform its obligations thereunder in accordance with the
terms thereof.

     Section 8.02.  Certain Matters Affecting the Trustee. Except
as otherwise provided in Section 8.01:

          (i)  The Trustee may request and rely upon and
     shall be protected in acting or refraining from acting
<PAGE>



<PAGE> 215

     upon any resolution, Officer's Certificate, certificate
     of auditors or any other certificate, statement,
     instrument, opinion, report, notice, request, consent,
     order, approval, bond or other paper or document
     believed by it to be genuine and to have been signed or
     presented by the proper party or parties;
     
          (ii) The Trustee may consult with counsel and any
     Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action
     taken or suffered or omitted by it hereunder in good
     faith and in accordance with such Opinion of Counsel;
     
          (iii)     The Trustee shall not be personally
     liable for any action taken or omitted by it in good
     faith and reasonably believed by it to be authorized or
     within the discretion or rights or powers conferred
     upon it by this Agreement;
     
          (iv) Prior to the occurrence of an Event of
     Default hereunder and after the curing of all Events of
     Default which may have occurred, the Trustee shall not
     be bound to make any investigation into the facts or
     matters stated in any resolution, certificate,
     statement, instrument, opinion, report, notice,
     request, consent, order, approval, bond or other paper
     or document, unless requested in writing to do so by
     the Holders of Certificates (including the Certificate
     Insurer, with respect to the Insured Certificates)
     evidencing Percentage Interests aggregating not less
     than 25% of the REMIC III Trust Fund; provided,
     however, that if the payment within a reasonable time
     to the Trustee of the costs, expenses or liabilities
     likely to be incurred by it in the making of such
     investigation is, in the opinion of the Trustee, not
     reasonably assured to the Trustee by the security, if
     any, afforded to it by the terms of this Agreement, the
     Trustee may require reasonable indemnity against such
     expense or liability as a condition to proceeding;
     
          (v)  The Trustee may execute the trust or any of
     the powers hereunder or perform any duties hereunder
     either directly or by or through agents or attorneys;
     
          (vi) The Trustee shall not be deemed to have
     knowledge or notice of any matter, including without
     limitation an Event of Default, unless actually known
     by a Responsible Officer, or unless written notice
     thereof referencing this Agreement or the Certificates
     is received at the Corporate Trust Office at the
     address set forth in Section 10.06; and
     
<PAGE>



<PAGE> 216

          (vii)     In no event shall the Trustee be held
     liable for acts of omissions of the Master Servicer
     (excepting the Trustee's own actions as Master
     Servicer).   No provision of this Agreement shall
     require the Trustee to expend or risk its own funds or
     otherwise incur any financial liability in the
     performance of any of its duties hereunder (except for
     the giving of required notices), or in the exercise of
     any of its rights or powers, if it shall have
     reasonable grounds for believing the repayment of such
     funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.
     
     Section 8.03.  Trustee Not Liable for Certificates or
Mortgage Loans. The recitals contained herein (other than
those relating to the due organization, power and authority
of the Trustee) and in the Certificates (other than the
execution of, and certificate of authentication on, the
Certificates) shall be taken as the statements of the
Company and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the
validity or sufficiency of this Agreement or of the
Certificates or any Mortgage Loan. The Trustee shall not be
accountable for the use or application by the Company of any
of the Certificates or of the proceeds of such Certificates,
or for the use or application of any funds paid to the
Master Servicer, the Servicers or the Company in respect of
the Mortgage Loans or deposited into the Custodial Accounts
for P&I, any Buydown Fund Account, or the Custodial Accounts
for P&I by any Servicer or into the Investment Account, or
the Certificate Account by the Master Servicer or the
Company.

     Section 8.04.  Trustee May Own Certificates. The Trustee or
any agent or affiliate of the Trustee, in its individual or
any other capacity, may become the owner or pledgee of
Certificates with the same rights it would have if it were
not Trustee.

     Section 8.05.  The Master Servicer to Pay Trustee's Fees and
Expenses. Subject to any separate written agreement with the
Trustee, the Master Servicer covenants and agrees to, and
the Master Servicer shall, pay the Trustee from time to
time, and the Trustee shall be entitled to payment, for all
services rendered by it in the execution of the trust hereby
created and in the exercise and performance of any of the
powers and duties hereunder of the Trustee. Except as
otherwise expressly provided herein, the Master Servicer
shall pay or reimburse the Trustee upon its request for all
reasonable expenses and disbursements incurred or made by
the Trustee in accordance with any of the provisions of this
Agreement and indemnify the Trustee from any loss, liability
<PAGE>



<PAGE> 217

or expense incurred by it hereunder (including the
reasonable compensation and the expenses and disbursements
of its counsel and of all persons not regularly in its
employ) except any such expense or disbursement as may arise
from its negligence or bad faith. Such obligation shall
survive the termination of this Agreement or resignation or
removal of the Trustee. The Company shall, at its expense,
prepare or cause to be prepared all federal and state income
tax and franchise tax and information returns relating to
the REMIC I Trust Fund, the REMIC II Trust Fund or the REMIC
III Trust Fund required to be prepared or filed by the
Trustee and shall indemnify the Trustee for any liability of
the Trustee arising from any error in such returns.

     Section 8.06.  Eligibility Requirements for Trustee. The
Trustee hereunder shall at all times be (i) an institution
insured by the FDIC, (ii) a corporation or association
organized and doing business under the laws of the United
States of America or of any state, authorized under such
laws to exercise corporate trust powers, having a combined
capital and surplus of not less than $50,000,000 and subject
to supervision or examination by federal or state authority
and (iii) acceptable to the Rating Agencies. If such
corporation or association publishes reports of condition at
least annually, pursuant to law or to the requirements of
any aforementioned supervising or examining authority, then
for the purposes of this Section 8.06, 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
Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign
immediately in the manner and with the effect specified in
Section 8.07.

     Section 8.07.  Resignation and Removal of Trustee. The
Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to
the Master Servicer. Upon receiving such notice of
resignation, the Master Servicer shall promptly appoint a
successor trustee by written instrument, in duplicate, one
copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no
successor trustee shall have been so appointed and shall
have accepted appointment within 30 days after the giving of
such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the
appointment of a successor trustee.

     If at any time the Trustee shall cease to be eligible
in accordance with the provisions of Section 8.06 and shall
fail to resign after written request therefor by the Master
<PAGE>



<PAGE> 218

Servicer, or if at any time the Trustee shall become
incapable of acting, or shall be adjudged bankrupt or
insolvent, or a receiver of the Trustee or of its property
shall be appointed, or any public officer shall take charge
or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation,
then the Master Servicer may remove the Trustee and appoint
a successor trustee by written instrument, in duplicate, one
copy of which instrument shall be delivered to the Trustee
so removed, one copy to the successor.

     The Holders of Certificates evidencing Percentage
Interests aggregating more than 50% of the REMIC III Trust
Fund may at any time remove the Trustee and appoint a
successor trustee by written instrument or instruments, in
triplicate, signed by such Holders or their attorneys in-
fact duly authorized, one complete set of which instruments
shall be delivered to the Master Servicer, one complete set
to the Trustee so removed and one complete set to the
successor so appointed.

     Any resignation or removal of the Trustee and
appointment of a successor trustee pursuant to any of the
provisions of this Section 8.07 shall become effective upon
acceptance of appointment by the successor trustee as
provided in Section 8.08. Any expenses associated with the
resignation of the Trustee shall be borne by the Trustee,
and any expenses associated with the removal of the Trustee
shall be borne by the Master Servicer.

     Section 8.08.  Successor Trustee. Any successor trustee
appointed as provided in Section 8.07 shall execute,
acknowledge and deliver to the Master Servicer and to its
predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such
successor trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights,
powers, duties and obligations of its predecessor hereunder,
with like effect as if originally named as Trustee herein.
The predecessor shall deliver to the successor trustee all
Mortgage Files, related documents, statements and all other
property held by it hereunder, and the Master Servicer and
the predecessor trustee shall execute and deliver such
instruments and do such other things as may reasonably be
required for more fully and certainly vesting and confirming
in the successor trustee all such rights, powers, duties and
obligations.

     No successor trustee shall accept appointment as
provided in this Section 8.08 unless at the time of such
appointment such successor trustee shall be eligible under
<PAGE>



<PAGE> 219

the provisions of Section 8.06.

     Upon acceptance of appointment by a successor trustee
as provided in this Section 8.08, the Master Servicer shall
mail notice of the succession of such trustee hereunder to
(i) all Certificateholders at their addresses as shown in
the Certificate Register, (ii) the Certificate Insurer and
(iii) the Rating Agencies. If the Master Servicer fails to
mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee
shall cause such notice to be mailed.

     Section 8.09.  Merger or Consolidation of Trustee. Any
corporation or association into which the Trustee may be
merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of
the Trustee, shall be the successor of the Trustee
hereunder, provided such resulting or successor corporation
shall be eligible under the provisions of Section 8.06,
without the execution or filing of any paper or any further
act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

     Section 8.10.  Appointment of Co-Trustee or Separate
Trustee. Notwithstanding any other provisions hereof, at any
time, for the purpose of meeting any legal requirements of
any jurisdiction in which any part of the REMIC I Trust
Fund, the REMIC II Trust Fund or REMIC III Trust Fund may at
the time be located, the Master Servicer and the Trustee
acting jointly shall have the power and shall execute and
deliver all instruments to appoint one or more Persons
approved by the Trustee to act as co-trustee or co-trustees,
jointly with the Trustee, or separate trustee or separate
trustees, of all or any part of the REMIC I Trust Fund, the
REMIC II Trust Fund or REMIC III Trust Fund and to vest in
such Person or Persons, in such capacity, such title to the
REMIC I Trust Fund, the REMIC II Trust Fund or REMIC III
Trust Fund, or any part thereof, and, subject to the other
provisions of this Section 8.10, such powers, duties,
obligations, rights and trusts as the Master Servicer and
the Trustee may consider necessary or desirable; provided,
that the Trustee shall remain liable for all of its
obligations and duties under this Agreement. If the Master
Servicer shall not have joined in such appointment within 15
days after the receipt by it of a request so to do, or in
case an Event of Default shall have occurred and be
continuing, the Trustee alone shall have the power to make
such appointment; provided, that the Trustee shall remain
liable for all of its obligations and duties under this
Agreement. No co-trustee or separate trustee hereunder shall
<PAGE>



<PAGE> 220

be required to meet the terms of eligibility as a successor
trustee under Section 8.06 hereunder and no notice to
Certificateholders of the appointment of co-trustee(s) or
separate trustee(s) shall be required under Section 8.08
hereof.

     In the case of any appointment of a co-trustee or
separate trustee pursuant to this Section 8.10, all rights,
powers, duties and obligations conferred or imposed upon the
Trustee shall be conferred or imposed upon and exercised or
performed by the Trustee and such separate trustee or co-
trustee jointly and severally, except to the extent that
under any law of any jurisdiction in which any particular
act or acts are to be performed by the Trustee (whether as
Trustee hereunder or as successor to the Master Servicer
hereunder), the 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 REMIC I Trust Fund, the REMIC II Trust Fund or
the REMIC III Trust Fund or any portion thereof in any such
jurisdiction) shall be exercised and performed by such
separate trustee or co-trustee at the direction of the
Trustee.

     Any notice, request or other writing given to the
Trustee shall be deemed to have been given to each of the
then separate trustee(s) and co-trustee(s), as effectively
as if given to each of them. Every instrument appointing any
separate trustee(s) or co-trustee(s) shall refer to this
Agreement and the conditions of this Article VIII. 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 Trustee or separately, as may be provided
therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement
relating to the conduct of, affecting the liability of, or
affording protection to, the Trustee. Every such instrument
shall be filed with the Trustee.

     Any separate trustee or co-trustee may, at any time,
constitute the 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 the trust shall vest in and be
exercised by the Trustee, to the extent permitted by law,
without the appointment of a new or successor trustee.

     Section 8.11.  Authenticating Agents. The Trustee may
<PAGE>



<PAGE> 221

appoint one or more Authenticating Agents which shall be
authorized to act on behalf of the Trustee in authenticating
Certificates. Wherever reference is made in this Agreement
to the authentication of Certificates by the Trustee or the
Trustee's certificate of authentication, such reference
shall be deemed to include authentication on behalf of the
Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be
acceptable to the Master Servicer and must be a corporation
or banking association organized and doing business under
the laws of the United States of America or of any state,
having a principal office and place of business in New York,
New York, having a combined capital and surplus of at least
$15,000,000, authorized under such laws to do a trust
business and subject to supervision or examination by
federal or state authorities.

     Any corporation into which any Authenticating Agent may
be merged or converted or with which it may be consolidated,
or any corporation resulting from any merger, conversion or
consolidation to which any Authenticating Agent shall be a
party, or any corporation succeeding to the corporate agency
business of any Authenticating Agent, shall continue to be
the Authenticating Agent so long as it shall be eligible in
accordance with the provisions of the first paragraph of
this Section 8.11 without the execution or filing of any
paper or any further act on the part of the Trustee or the
Authenticating Agent.

     Any Authenticating Agent may at any time resign by
giving written notice of resignation to the Trustee and to
the Master Servicer. The Trustee may, upon prior written
approval of the Master Servicer, at any time terminate the
agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the
Master Servicer. Upon receiving a notice of resignation or
upon such a termination, or in case at any time any
Authenticating Agent shall cease to be eligible in
accordance with the provisions of the first paragraph of
this Section 8.11, the Trustee may appoint, upon prior
written approval of the Master Servicer, a successor
Authenticating Agent, shall give written notice of such
appointment to the Master Servicer and shall mail notice of
such appointment to all Certificateholders. Any successor
Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers,
duties and responsibilities of its predecessor hereunder,
with like effect as if originally named as Authenticating
Agent. Any reasonable compensation paid to an Authenticating
Agent shall be a reimbursable expense pursuant to Section
8.05 if paid by the Trustee.
<PAGE>



<PAGE> 222


     Section 8.12.  Paying Agents. The Trustee may appoint one or
more Paying Agents which shall be authorized to act on
behalf of the Trustee in making withdrawals from the
Certificate Account, and distributions to Certificateholders
as provided in Section 4.01, Section 4.04, Section 4.06(a)
and Section 9.01(b) to the extent directed to do so by the
Master Servicer. Wherever reference is made in this
Agreement to the withdrawal from the Certificate Account by
the Trustee, such reference shall be deemed to include such
a withdrawal on behalf of the Trustee by a Paying Agent.
Whenever reference is made in this Agreement to a
distribution by the Trustee or the furnishing of a statement
to Certificateholders by the Trustee, such reference shall
be deemed to include such a distribution or furnishing on
behalf of the Trustee by a Paying Agent. Each Paying Agent
shall provide to the Trustee such information concerning the
Certificate Account as the Trustee shall request from time
to time. Each Paying Agent must be reasonably acceptable to
the Master Servicer and must be a corporation or banking
association organized and doing business under the laws of
the United States of America or of any state, having a
principal office and place of business in New York, New
York, having a combined capital and surplus of at least
$15,000,000, authorized under such laws to do a trust
business and subject to supervision or examination by
federal or state authorities.

     Any corporation into which any Paying Agent may be
merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or
consolidation to which any Paying Agent shall be a party, or
any corporation succeeding to the corporate agency business
of any Paying Agent, shall continue to be the Paying Agent
provided that such corporation after the consummation of
such merger, conversion, consolidation or succession meets
the eligibility requirements of this Section 8.12.

     Any Paying Agent may at any time resign by giving
written notice of resignation to the Trustee and to the
Master Servicer; provided, that the Paying Agent has
returned to the Certificate Account or otherwise accounted,
to the reasonable satisfaction of the Master Servicer, for
all amounts it has withdrawn from the Certificate Account.
The Trustee may, upon prior written approval of the Master
Servicer, at any time terminate the agency of any Paying
Agent by giving written notice of termination to such Paying
Agent and to the Master Servicer. Upon receiving a notice of
resignation or upon such a termination, or in case at any
time any Paying Agent shall cease to be eligible in
accordance with the provisions of the first paragraph of
this Section 8.12, the Trustee may appoint, upon prior
written approval of the Master Servicer, a successor Paying
<PAGE>



<PAGE> 223

Agent, shall give written notice of such appointment to the
Master Servicer and shall mail notice of such appointment to
all Certificateholders. Any successor Paying Agent upon
acceptance of its appointment hereunder shall become vested
with all the rights, powers, duties and responsibilities of
its predecessor hereunder, with like effect as if originally
named as Paying Agent. Any reasonable compensation paid to
any Paying Agent shall be a reimbursable expense pursuant to
Section 8.05 if paid by the Trustee.

                         ARTICLE IX
                              
                         Termination
                              
     Section 9.01.  Termination Upon Repurchase by the Company or
Liquidation of All Mortgage Loans.

     (a)  Except as otherwise set forth in this Article IX,
including, without limitation, the obligation of the Master
Servicer to make payments to Certificateholders as hereafter
set forth, the respective obligations and responsibilities
of the Company, the Master Servicer and the Trustee created
hereby shall terminate upon (i) the repurchase by the
Company pursuant to the following paragraph of this Section
9.01(a) of all Mortgage Loans and all property acquired in
respect of any Mortgage Loan remaining in the Trust Fund at
a price equal, after the deduction of related advances, to
the sum of (x) the excess of (A) 100% of the aggregate
outstanding Principal Balance of such Mortgage Loans (other
than Liquidated Mortgage Loans) plus accrued interest at the
applicable Pass-Through Rate with respect to such Mortgage
Loan (other than a Liquidated Mortgage Loan) through the
last day of the month of such repurchase, over (B) with
respect to any Mortgage Loan which is not a Liquidated
Mortgage Loan, the amount of the Bankruptcy Loss incurred
with respect to such Mortgage Loan as of the date of such
repurchase by the Company to the extent that the Principal
Balance of such Mortgage Loan has not been previously
reduced by such Bankruptcy Loss, and (y) the appraised fair
market value as of the effective date of the termination of
the trust created hereby of (A) all property in the Trust
Fund which secured a Mortgage Loan and which was acquired by
foreclosure or deed in lieu of foreclosure after the Cut-Off
Date, including related Insurance Proceeds, and (B) all
other property in the Trust Fund, any such appraisal to be
conducted by an appraiser mutually agreed upon by the
Company and the Trustee, or (ii) the later of the final
payment or other liquidation (or any advance with respect
thereto) of the last Mortgage Loan remaining in the Trust
Fund or the disposition of all property acquired upon
foreclosure in respect of any Mortgage Loan, and the payment
to Certificateholders of all amounts required to be paid to
<PAGE>



<PAGE> 224

them hereunder and the payment to the Certificate Insurer of
any remaining amounts pursuant to the priority set forth in
the definition of REMIC I Distribution Amount of the Class
IV-A-5 Reimbursement Amount; provided, however, that in no
event shall the trusts created hereby continue beyond the
expiration of 21 years from the death of the survivor of the
issue of Joseph P. Kennedy, the late ambassador of the
United States to the Court of St. James, living on the date
hereof.

     The Company may repurchase the outstanding Mortgage
Loans and any Mortgaged Properties acquired by the Trust
Fund at the price stated in clause (i) of the preceding
paragraph provided that the aggregate Principal Balance of
the Mortgage Loans at the time of any such repurchase
aggregates less than five percent of the aggregate Principal
Balance of the Mortgage Loans as of the Cut-Off Date. If
such right is exercised, the Company shall provide to the
Trustee and the Certificate Insurer (and to the Master
Servicer, if the Company is no longer acting as Master
Servicer) the written certification of an officer of the
Company (which certification shall include a statement to
the effect that all amounts required to be paid in order to
repurchase the Mortgage Loans have been deposited in the
Certificate Account) and the Trustee shall promptly execute
all instruments as may be necessary to release and assign to
the Company the Mortgage Files and any foreclosed Mortgaged
Property pertaining to the Trust Fund.

     In no event shall the Company be required to expend any
amounts other than those described in the first paragraph of
this Section 9.01(a) in order to terminate the Trust Fund or
repurchase the Mortgage Loans under this Section 9.01.

     (b)  Notice of any termination, specifying the date
upon which the Certificateholders may surrender their
Certificates to the Trustee for payment and cancellation,
shall be given promptly by letter from the Trustee to
Certificateholders mailed not less than 30 days prior to
such final distribution, specifying (i) the date upon which
final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office of
the Certificate Registrar therein designated (the
"Termination Date"), (ii) the amount of such final payment
(the "Termination Payment") and (iii) that the Record Date
otherwise applicable to the Distribution Date upon which the
Termination Date occurs is not applicable, payments being
made only upon presentation and surrender of the
Certificates at the office of the Certificate Registrar
therein specified. Upon any such notice, the Certificate
Account shall terminate subject to the Master Servicer's
obligation to hold all amounts payable to Certificateholders
<PAGE>



<PAGE> 225

in trust without interest pending such payment.

     In the event that all of the Certificateholders shall
not surrender their Certificates for cancellation within six
months after the Termination Date, the Company shall give a
second written notice to the remaining Certificateholders to
surrender their Certificates for cancellation and receive
the Termination Payment with respect thereto. If within one
year after the second notice all the Certificates shall not
have been surrendered for cancellation, the Company may take

     Section 9.02.  Additional Termination Requirements.

option as provided in Section 9.01, the REMIC I Trust Fund,
the REMIC II Trust Fund and the REMIC III Trust Fund shall
be terminated in accordance with the following additional
requirements, unless the Company, at its own expense,
obtains for the Trustee and the Certificate Insurer an
Opinion of Counsel to the effect that the failure of the
REMIC I Trust Fund, the REMIC II Trust Fund and REMIC III
Trust Fund to comply with the requirements of this Section
9.02 will not (i) result in the imposition of taxes on
"prohibited transactions" of the REMIC I Trust Fund, the
REMIC II Trust Fund and the REMIC III Trust Fund as
described in Section 860F of the Code, or (ii) cause the
REMIC I Trust Fund, the REMIC II Trust Fund or the REMIC III
Trust Fund to fail to qualify as a REMIC at any time that
any Certificates are outstanding:

          (i)  Within 90 days prior to the final
     Distribution Date set forth in the notice given by the
     Trustee under Section 9.01, the Company, in its
     capacity as agent of the Tax Matters Person shall
     prepare the documentation required and adopt a plan of
     complete liquidation on behalf of the REMIC I Trust
     Fund, the REMIC II Trust Fund and the REMIC III Trust
     Fund meeting the requirements of a qualified
     liquidation under Section 860F of the Code and any
     regulations thereunder, as evidenced by an Opinion of
     Counsel obtained at the expense of the Company, on
     behalf of the REMIC I Trust Fund, the REMIC II Trust
     Fund and the REMIC III Trust Fund; and
     
          (ii) At or after the time of adoption of such a

     REMIC I Trust Fund, the REMIC II Trust Fund and the
     REMIC III Trust Fund to the Company for cash in the
     amount specified in Section 9.01.
     
     (b)  By its acceptance of any Residual Certificate, the
Holder thereof hereby agrees to authorize the Company to
adopt such a plan of complete liquidation upon the written
request of the Company and to take such other action in
connection therewith as may be reasonably requested by the
Company.

                  Miscellaneous Provisions
                              
     Section 10.01. Amendment.

     (a)  This Agreement may be amended from time to time by
the Master Servicer, the Company and the Trustee, without
the consent of any of the Certificateholders, but with the
prior written consent of the Certificate Insurer with
respect to any amendment that adversely affects the
interests of any of the Insured Certificateholders: (i) to
cure any ambiguity; (ii) to correct or supplement any
provision herein which may be defective or inconsistent with
any other provisions herein; (iii) to comply with any
requirements imposed by the Code or any regulations
thereunder; (iv) to correct the description of any property
at any time included in the REMIC I Trust Fund, the REMIC II
Trust Fund or the REMIC III Trust Fund, or to assure the
conveyance to the Trustee of any property included in the
REMIC I Trust Fund, the REMIC II Trust Fund or the REMIC III
Trust Fund; and (v) pursuant to Section 5.01(c)(v). No such
amendment (other than one entered into pursuant to clause
(iii) of the preceding sentence) shall adversely affect in
any material respect the interest of any Certificateholder.
Prior to entering into any amendment without the consent of
Certificateholders pursuant to this paragraph, the Trustee
may require an Opinion of Counsel to the effect that such
amendment is permitted under this paragraph. The placement
of an "original issue discount" legend on, or any change
required to correct any such legend previously placed on a
Certificate shall not be deemed any amendment to this
Agreement.

     (b)  This Agreement may also be amended from time to
time by the Master Servicer, the Company and the Trustee
with the consent of the Holders of Certificates evidencing
Percentage Interests aggregating not less than 66% of the
<PAGE>



<PAGE> 227

REMIC III Trust Fund for the purpose of adding any
provisions to, or changing in any manner or eliminating any
of the provisions of, this Agreement or of modifying in any
manner the rights of the Certificateholders; provided,
however, that no such amendment shall, without the consent
of the Holder of each Certificate affected thereby (i)
reduce in any manner the amount of, or delay the timing of,
distributions of principal or interest required to be made
hereunder or reduce the Certificateholder's Percentage
Interest, the Certificate Interest Rate or the Termination
Payment with respect to any of the Certificates, (ii) reduce
the percentage of Percentage Interests specified in this
Section 10.01 which are required to amend this Agreement,
(iii) create or permit the creation of any lien against any
part of the REMIC I Trust Fund, the REMIC II Trust Fund or
the REMIC III Trust Fund, or (iv) modify any provision in
any way which would permit an earlier retirement of the
Certificates.

     Promptly after the execution of any such amendment, the
Trustee shall furnish written notification of the substance
of such amendment to each Certificateholder. Any failure to
provide such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any
such amendment.

     It shall not be necessary for the consent of
Certificateholders under this Section 10.01 to approve the
particular form of any proposed amendment, but it shall be
sufficient if such consent shall approve the substance
thereof. The manner of obtaining such consents and of
evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

     Section 10.02. Recordation of Agreement. To the extent
permitted by applicable law, this Agreement is subject to
recordation in all appropriate public offices for real
property records in all the counties or the comparable
jurisdictions in which any Mortgaged Property is situated,
and in any other appropriate public recording office or
elsewhere, such recordation to be effected by the Company
and at its expense on direction by the Trustee, but only
upon direction accompanied by an Opinion of Counsel to the
effect that such recordation materially and beneficially
affects the interests of the Certificateholders.  Without
limiting the foregoing, the Trustee shall make the filings
required by Chapter 182 of the Massachusetts General Laws.

     Section 10.03. Limitation on Rights of Certificateholders.
The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement, the REMIC I Trust Fund,
<PAGE>



<PAGE> 228

the REMIC II Trust Fund or REMIC III Trust Fund, nor entitle
such Certificateholder's legal representatives or heirs to
claim an accounting or to take any action or proceeding in
any court for a partition or winding-up of the REMIC I Trust
Fund, the REMIC II Trust Fund or the REMIC III Trust Fund,
nor otherwise affect the rights, obligations and liabilities
of the parties hereto or any of them.

     No Certificateholder shall have any right to vote or in
any manner otherwise to control the operation and management
of the REMIC I Trust Fund, the REMIC II Trust Fund or the
REMIC III Trust Fund or the obligations of the parties
hereto (except as provided in Section 5.09, Section 7.01,
Section 8.01, Section 8.02, Section 8.07, Section 10.01 and
this Section 10.03), nor shall anything herein set forth, or
contained in the terms of the Certificates, be construed so
as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any
Certificateholder be under any liability to any third person
by reason of any action taken by the parties to this
Agreement pursuant to any provision hereof.

     No Certificateholder shall have any right by virtue or
by availing of any provision of this Agreement to institute
any suit, action or proceeding in equity or at law upon or
under or with respect to this Agreement, unless such Holder
previously shall have given to the Trustee a written notice
of default and of the continuance thereof, as hereinbefore
provided, and unless also the Holders of Certificates
evidencing Percentage Interests aggregating not less than
25% of the REMIC III Trust Fund shall have made written
request upon the Trustee to institute such action, suit or
proceeding in its own name as Trustee hereunder and shall
have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to
be incurred therein or thereby, and the Trustee, for 60 days
after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any
such action, suit or proceeding. However, the Trustee is
under no obligation to exercise any of the extraordinary
trusts or powers vested in it by this Agreement or to make
any investigation of matters arising hereunder or to
institute, conduct or defend any litigation hereunder or in
relation hereto at the request, order or direction of any of
the Certificateholders unless such Certificateholders have
offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be
incurred therein or thereby. It is understood and intended,
and expressly covenanted by each Certificateholder with
every other Certificateholder and the Trustee, that no one
or more Holders of Certificates shall have any right in any
manner whatever by virtue or by availing of any provision of
<PAGE>



<PAGE> 229

this Agreement to affect, disturb or prejudice the rights of
the Holders of any other of such Certificates, or to obtain
or seek to obtain priority over or preference to any other
such Holder, or to enforce any right under this Agreement,
except in the manner herein provided and for the equal,
ratable and common benefit of all Certificateholders. For
the protection and enforcement of the provisions of this
Section 10.03, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given
either at law or in equity.

     For so long as no Certificate Insurer Default exists
(and whether or not any payments with respect to Deficiency
Amounts or Preference Amounts have been made), the
Certificate Insurer shall be deemed to be the sole Holder of
all outstanding Insured Certificates with respect to any
rights hereunder (other than the right to receive
distributions on such Insured Certificates, except as
provided in Section 3.22); provided that such rights may not
be used to reduce the rights of the Insured
Certificateholders to receive distributions or to otherwise
impair their rights under this Agreement as further
described in the definition of "Certificateholder."

     Section 10.04. Access to List of Certificateholders. The
Certificate Registrar shall furnish or cause to be furnished
to the Trustee, within 30 days after receipt of a request by
the Trustee in writing, a list, in such form as the Trustee
may reasonably require, of the names and addresses of the
Certificateholders as of the most recent Record Date for
payment of distributions to such Certificateholders.

     If three or more Certificateholders (hereinafter
referred to as "applicants") apply in writing to the
Trustee, and such application states that the applicants
desire to communicate with other Certificateholders with
respect to their rights under this Agreement or under the
Certificates and is accompanied by a copy of the
communication which such applicants propose to transmit,
then the Trustee shall, within five Business Days after the
receipt of such list from the Certificate Registrar, afford
such applicants access during normal business hours to the
most recent list of Certificateholders held by the Trustee.
If such a list is as of a date more than 90 days prior to
the date of receipt of such applicants' request, the Trustee
shall promptly request from the Certificate Registrar a
current list as provided above, and shall afford such
applicants access to such list promptly upon receipt.

     Every Certificateholder, by receiving and holding the
same, agrees with the Master Servicer and the Trustee that
neither the Master Servicer nor the Trustee shall be held
<PAGE>

which such information was derived.

This Certificate represents ownership of a "regular interest" in
a "real estate mortgage investment conduit," as those terms are
defined in Sections 860G and 860D, respectively, of the Internal
Revenue Code of 1986, as amended. The issue date (the "Issue
Date") of this Certificate is November 30, 1998. [Assuming that
the Mortgage Loans underlying the Certificates prepay at the
prepayment assumption used by the issuer in pricing this
Certificate (i.e., 275% of the Standard Prepayment Assumption as
described in the Prospectus Supplement), this Certificate has
been issued with original issue discount ("OID") of no more than
$            per $100,000 of initial Certificate Principal
Balance, the yield to maturity is     %, and the amount of OID
attributable to the short period is not more than $
per $100,000 of initial Certificate Principal Balance, computed
under the exact method. No representation is made that the
Mortgage Loans will prepay at a rate based on the Standard
Prepayment Assumption or any other rate.]

Unless this Certificate is presented by an authorized
representative of The Depository Trust Company, a New York
corporation ("DTC"), to the Trustee or its agent for registration
of transfer, exchange, or payment, and any Certificate issued is
registered in the name of Cede & Co. or such other name as is
requested by an authorized representative of DTC (and any payment
is made to Cede & Co. or to such other entity as is requested by
an authorized representative of DTC), ANY TRANSFER, PLEDGE OR

defined in Sections 860G and 860D, respectively, of the Internal
Revenue Code of 1986, as amended. The issue date (the "Issue

the Mortgage Loans underlying the Certificates prepay at the
prepayment assumption used by the issuer in pricing this
Certificate (i.e., 100% of the Basic Prepayment Assumption as

been issued with original issue discount ("OID") of no more than
$            per $100,000 of initial Certificate Principal
Balance, the yield to maturity is       %, and the amount of OID
attributable to the short period is not more than $
per $100,000 of initial Certificate Principal Balance, computed
under the exact method. No representation is made that the
Mortgage Loans will prepay at a rate based on the Basic
Prepayment Assumption or any other rate.]

such Certificateholder's Percentage Interest represented by this
Certificate in the portion of the REMIC I Available Distribution
Amount for such Distribution Date then distributable on the

Registrar.

     Reference is hereby made to the further provisions of this
Certificate set forth below, which further provisions shall for

                  PNC MORTGAGE SECURITIES CORP.
                MORTGAGE PASS-THROUGH CERTIFICATE
                                
     This Certificate is one of a duly authorized issue of
Certificates designated as Mortgage Pass-Through Certificates of
the Series and Class specified hereon (herein called the
"Certificates") and representing certain interests in the REMIC I
Trust Fund.

     The Certificates do not represent an obligation of, or an
interest in, the Company or any of its affiliates and are not
insured or guaranteed by any governmental agency. The
Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as
more specifically set forth herein and in the Pooling Agreement.
In the event funds are advanced with respect to any Mortgage
Loan, such advance is reimbursable to the Master Servicer from
the related recoveries on such Mortgage Loan or from other cash
deposited in the Certificate Account to the extent that such
advance is not otherwise recoverable.

     As provided in the Pooling Agreement, withdrawals from the
Certificate Account may be made from time to time for purposes
other than distributions to Certificateholders, such purposes
including reimbursement to the Master Servicer of advances made,
or certain expenses incurred, by it.

     The Pooling Agreement permits, with certain exceptions
therein provided, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the
Certificateholders under the Pooling Agreement at any time by the
Company, the Master Servicer and the Trustee with the consent of
the Holders of the Certificates evidencing Percentage Interests
aggregating not less than 66% of the REMIC III Trust Fund.  The
Pooling Agreement also permits the amendment thereof, in certain
limited circumstances, without the consent of the Holders of any
of the Certificates.

<PAGE>



<PAGE> 302

     As provided in the Pooling Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate
is registrable in the Certificate Register upon surrender of this
Certificate for registration of transfer at the offices of the
Certificate Registrar or the office maintained by the Trustee in
the City and State of New York, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Trustee or any
Authenticating Agent 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 Percentage Interest set forth hereinabove will be issued
to the designated transferee or transferees.

     No transfer of a Certificate will be made unless such
transfer is exempt from or is made in accordance with the
registration requirements of the Securities Act of 1933, as
amended (the "Securities Act") and any applicable state
securities laws. In the event that a transfer is to be made
without registration or qualification under applicable laws, (i)
in the event such transfer is made pursuant to Rule 144A under
the Securities Act, the Company and the Trustee shall require the
transferee to execute an investment letter in substantially the
form attached as Exhibit L to the Pooling Agreement, which
investment letter shall not be an expense of the Company, the
Master Servicer or the Trustee and (ii) in the event that such a
transfer is not made pursuant to Rule 144A under the Securities
Act, the Company may require an Opinion of Counsel satisfactory
to the Company that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not
be an expense of the Company, the Master Servicer or the Trustee.
Neither the Company nor the Trustee will register the Certificate
under the Securities Act, qualify the Certificate under any state
securities law or provide registration rights to any purchaser.
Any Holder desiring to effect such transfer shall, and does
hereby agree to, indemnify the Trustee, the Company and the
Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such
federal and state laws.

     The Certificates are issuable only as registered
Certificates without coupons in Authorized Denominations
specified in the Pooling Agreement. As provided in the Pooling
Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of Authorized
Denominations evidencing the same aggregate interest in the
portion of the REMIC I Available Distribution Amount
distributable on this Class of Certificate, as requested by the
Holder surrendering the same.

     A reasonable service charge may be made for any such
registration of transfer or exchange, and the Trustee may require
<PAGE>



<PAGE> 303

payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

     The Company, the Trustee and the Certificate Registrar and
any agent of the Company, the Trustee or the Certificate
Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the
Company, the Trustee, the Certificate Registrar nor any such
agent shall be affected by notice to the contrary.

     The obligations created by the Pooling Agreement and the
trust funds created thereby shall terminate upon (i) the later of
the maturity or other liquidation (including repurchase by the
Company) of the last Mortgage Loan remaining in the REMIC I Trust
Fund or the disposition of all property acquired upon foreclosure
or deed in lieu of foreclosure of any Mortgage Loan, and (ii) the
payment to Certificateholders of all amounts held by the Trustee
and required to be paid to them pursuant to the Pooling
Agreement. In the event that the Company repurchases any Mortgage
Loan pursuant to the Pooling Agreement, such Pooling Agreement
generally requires that the Trustee distribute to the
Certificateholders in the aggregate an amount equal to 100% of
the unpaid Principal Balance of such Mortgage Loan, plus accrued
interest at the applicable Pass-Through Rate to the next
scheduled Due Date for the Mortgage Loan. The Pooling Agreement
permits, but does not require, the Company to repurchase from the
REMIC I Trust Fund all Mortgage Loans at the time subject thereto
and all property acquired in respect of any Mortgage Loan upon
payment to the Certificateholders of the amounts specified in the
Pooling Agreement. The exercise of such right will effect early
retirement of the Certificates, the Company's right to repurchase
being subject to the aggregate unpaid Principal Balance of the
Mortgage Loans at the time of repurchase being less than five
percent (5%) of the aggregate unpaid Principal Balance of the
Mortgage Loans as of the Cut-Off Date.

In the event funds are advanced with respect to any Mortgage
Loan, such advance is reimbursable to the Master Servicer from
the related recoveries on such Mortgage Loan or from other cash
deposited in the Certificate Account to the extent that such
advance is not otherwise recoverable.

     As provided in the Pooling Agreement, withdrawals from the
Certificate Account may be made from time to time for purposes
other than distributions to Certificateholders, such purposes
including reimbursement to the Master Servicer of advances made,
or certain expenses incurred, by it.

     The Pooling Agreement permits, with certain exceptions
therein provided, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the
Certificateholders under the Pooling Agreement at any time by the
Company, the Master Servicer and the Trustee with the consent of
the Holders of the Certificates evidencing Percentage Interests
aggregating not less than 66% of the REMIC III Trust Fund.  The
Pooling 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 Pooling Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate
is registrable in the Certificate Register upon surrender of this
Certificate for registration of transfer at the offices of the
Certificate Registrar or the office maintained by the Trustee in

by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Trustee or any
Authenticating Agent 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 Percentage Interest set forth hereinabove will be issued
to the designated transferee or transferees.

     No transfer of a Certificate will be made unless such
transfer is exempt from or is made in accordance with the
registration requirements of the Securities Act of 1933, as
amended (the "Securities Act") and any applicable state
securities laws. In the event that a transfer is to be made
without registration or qualification under applicable laws, (i)
in the event such transfer is made pursuant to Rule 144A under
the Securities Act, the Company and the Trustee shall require the
transferee to execute an investment letter in substantially the

Act, the Company may require an Opinion of Counsel satisfactory
to the Company that such transfer may be made without such

registration or qualification, which Opinion of Counsel shall not
be an expense of the Company, the Master Servicer or the Trustee.
Neither the Company nor the Trustee will register the Certificate
under the Securities Act, qualify the Certificate under any state
securities law or provide registration rights to any purchaser.
Any Holder desiring to effect such transfer shall, and does
hereby agree to, indemnify the Trustee, the Company and the
Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such
federal and state laws.

     The Certificates are issuable only as registered
Certificates without coupons in Authorized Denominations
specified in the Pooling Agreement. As provided in the Pooling
Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of Authorized
Denominations evidencing the same aggregate interest in the
portion of the REMIC II Available Distribution Amount
distributable on this Class of Certificate, as requested by the
Holder surrendering the same.

     A reasonable service charge may be made for any such
registration of transfer or exchange, and the Trustee may require
payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

     The Company, the Trustee and the Certificate Registrar and
any agent of the Company, the Trustee or the Certificate
Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the
Company, the Trustee, the Certificate Registrar nor any such
agent shall be affected by notice to the contrary.

     The obligations created by the Pooling Agreement and the
trust funds created thereby shall terminate upon (i) the later of
the maturity or other liquidation (including repurchase by the
Company) of the last Mortgage Loan remaining in the REMIC I Trust
Fund or the disposition of all property acquired upon foreclosure
or deed in lieu of foreclosure of any Mortgage Loan, and (ii) the
payment to Certificateholders of all amounts held by the Trustee
and required to be paid to them pursuant to the Pooling
Agreement. In the event that the Company repurchases any Mortgage
Loan pursuant to the Pooling Agreement, such Pooling Agreement
generally requires that the Trustee distribute to the
Certificateholders in the aggregate an amount equal to 100% of
the unpaid Principal Balance of such Mortgage Loan, plus accrued
interest at the applicable Pass-Through Rate to the next
scheduled Due Date for the Mortgage Loan. The Pooling Agreement
permits, but does not require, the Company to repurchase from the
REMIC I Trust Fund all Mortgage Loans at the time subject thereto
and all property acquired in respect of any Mortgage Loan upon
payment to the Certificateholders of the amounts specified in the
<PAGE>



<PAGE> 310

Pooling Agreement. The exercise of such right will effect early
retirement of the Certificates, the Company's right to repurchase
being subject to the aggregate unpaid Principal Balance of the
Mortgage Loans at the time of repurchase being less than five
percent (5%) of the aggregate unpaid Principal Balance of the
Mortgage Loans as of the Cut-Off Date.

all duties incident to the origination, sale and servicing of the
mortgage loans subject to this Agreement.  In the performance  of
its  servicing duties, the Company shall exercise the same degree
of  care  it exercises when servicing mortgage loans for its  own

than  a  reasonable prudent servicer would exercise under similar
circumstances.  In addition, the Company shall comply with all of
the  provisions of the Guides and with all other requirements and
instructions  of  PNC Mortgage.  The Company shall  perform  such
duties  at  its  sole  expense,  except  as  otherwise  expressly
provided in the Guides.

this   Agreement,   the   Company   shall   make   all   of   the
representations, warranties and covenants set forth in the  Guide
and,  in  the event of the breach of any of such representations,
warranties  and  covenants, PNC Mortgage shall have  all  of  the
remedies  available at law or in equity, as well as  all  of  the
remedies  set forth in the Guide, including, but not limited  to,
repurchase   and   indemnification.   The   representations   and
warranties made by the Company with respect to any mortgage  loan

PNC  Mortgage  upon the breach thereof, shall survive:   (a)  any
investigation  regarding  the  mortgage  loan  conducted  by  PNC
Mortgage, its assignees or designees, (b) the liquidation of  the
mortgage  loan,  (c)  the purchase of the mortgage  loan  by  PNC
Mortgage,  its  assignee or designee, (d) the repurchase  of  the
mortgage  loan  by  the Company and (e) the termination  of  this
Agreement.

     4.   Compensation.  The Company shall be compensated for its
services hereunder as specified in the Guides.

      5.   No Assignment.  This Agreement may not be assigned  by
the  Company  without the prior written consent of PNC  Mortgage.
The Company hereby consents to the assignment by PNC Mortgage  of
all  or  any  part  of  its  rights and  obligations  under  this
Agreement to any affiliate designated by PNC Mortgage.  Any other
transfer  by  PNC Mortgage will be allowed and be effective  upon
written notice by PNC Mortgage to the Company.

      6.   Prior Agreements.  This Agreement supersedes any prior
agreements  and  understandings  between  PNC  Mortgage  and  the
Company  governing the subject matter hereof; provided,  however,
the  Company  shall  not be released from any  responsibility  or
liability  that  may  have  arisen  under  such  agreements   and
understanding.

      7.    Effective Date of Agreement.  This Agreement  is  not
effective  until it is executed and accepted by PNC  Mortgage  at
its home office in Illinois.

      8.    Notices.   All  notices, requests, demands  or  other
communications that are to be given under this Agreement shall be
in  writing, addressed to the appropriate parties, and  shall  be
sent   by  certified  mail,  return  receipt  requested,  postage
prepaid, if to the Company, at the address below and, if  to  PNC
Mortgage,   to  the  appropriate  address  or  facsimile   number
specified  in  the Guides.  Any such notice, request,  demand  or
other communication shall be deemed effective upon receipt.

      9.    Independent Contractor.  At no time shall the Company
represent  that  it  is  acting as an  agent,  partner  or  joint
venturer of PNC Mortgage.  The Company shall at all times act  as
an independent contracting party.

      10.   Amendment.   This Agreement may  not  be  amended  or
modified orally, and no provision of this Agreement may be waived
or  amended,  except in writing signed by the party against  whom
enforcement  is sought.  Such a written waiver or amendment  must
expressly reference this Agreement.  However, by their terms  the
Guides  may be amended or supplemented by PNC Mortgage from  time
to time.  Any such amendment(s) to the Guides shall be in writing

and be binding upon the parties hereto on and after the effective
date specified therein.

       11.     Miscellaneous.   This  Agreement,  including   all
documents  incorporated  by  reference  herein,  constitutes  the
entire  understanding between the parties hereto  and  supersedes
all  other  agreements,  covenants, representations,  warranties,
understandings  and communications between the  parties,  whether
written or oral, with respect to the transactions contemplated by
this  Agreement.  All section headings contained herein  are  for
convenience  only  and shall not be construed  as  part  of  this
Agreement.  Any provision of this Agreement that is prohibited or
unenforceable  in any jurisdiction shall as to such  jurisdiction
be   ineffective   to   the  extent  of   such   prohibition   or
unenforceability  without  invalidating  the  remaining  portions
hereof  or  affecting  the  validity or  enforceability  of  such
provision  in  any  other jurisdiction,  and  to  this  end,  the
provisions  hereof  are  severable.   This  Agreement  shall   be
governed  by,  and  construed and enforced  in  accordance  with,
applicable  federal  laws  and laws of  the  State  of  Illinois,
without  reference to conflict of laws principles. This Agreement
may  be executed in one or more counterparts, each of which shall
constitute an original and all of which shall constitute the same
Agreement.

     IN WITNESS WHEREOF, the parties have executed this Agreement
by  proper officials duly authorized on the dates hereinafter set
forth.   This Agreement shall take effect as of the date  of  its
execution in original or facsimile signature by a duly authorized
officer of PNC Mortgage.

Registrar.

collections and recoveries respecting the Mortgage Loans, all as
more specifically set forth herein and in the Pooling Agreement.
In the event funds are advanced with respect to any Mortgage
Loan, such advance is reimbursable to the Master Servicer from
the related recoveries on such Mortgage Loan or from other cash
deposited in the Certificate Account to the extent that such
advance is not otherwise recoverable.

     As provided in the Pooling Agreement, withdrawals from the
Certificate Account may be made from time to time for purposes
other than distributions to Certificateholders, such purposes
including reimbursement to the Master Servicer of advances made,
or certain expenses incurred, by it.

     The Pooling Agreement permits, with certain exceptions
therein provided, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the
Certificateholders under the Pooling Agreement at any time by the
Company, the Master Servicer and the Trustee with the consent of
the Holders of the Certificates evidencing Percentage Interests
aggregating not less than 66% of the REMIC III Trust Fund. Any
such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon 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 Pooling 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 Pooling Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate
is registrable in the Certificate Register upon surrender of this
Certificate for registration of transfer at the offices of the
Certificate Registrar or the office maintained by the Trustee in
the City and State of New York, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of
<PAGE>



<PAGE> 322

transfer in form satisfactory to the Trustee or any
Authenticating Agent 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 Percentage Interest set forth hereinabove will be issued
to the designated transferee or transferees.

     No transfer of a Certificate will be made unless such
transfer is exempt from or is made in accordance with the
registration requirements of the Securities Act of 1933, as
amended (the "Securities Act") and any applicable state
securities laws. In the event that a transfer is to be made
without registration or qualification under applicable laws, (i)
in the event such transfer is made pursuant to Rule 144A under
the Securities Act, the Company and the Trustee shall require the
transferee to execute an investment letter in substantially the
form attached as Exhibit L to the Pooling Agreement, which
investment letter shall not be an expense of the Company, the
Master Servicer or the Trustee and (ii) in the event that such a
transfer is not made pursuant to Rule 144A under the Securities
Act, the Company may require an Opinion of Counsel satisfactory
to the Company that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not
be an expense of the Company, the Master Servicer or the Trustee.
Neither the Company nor the Trustee will register the Certificate
under the Securities Act, qualify the Certificate under any state
securities law or provide registration rights to any purchaser.
Any Holder desiring to effect such transfer shall, and does
hereby agree to, indemnify the Trustee, the Company and the
Master Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such
federal and state laws.

     The Certificates are issuable only as registered
Certificates without coupons in Authorized Denominations
specified in the Pooling Agreement. As provided in the Pooling
Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of Authorized
Denominations evidencing the same aggregate interest in the
portion of the REMIC III Available Distribution Amount
distributable on this Class of Certificate, as requested by the
Holder surrendering the same.

     A reasonable service charge may be made for any such
registration of transfer or exchange, and the Trustee may require
payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

     The Company, the Trustee and the Certificate Registrar and
any agent of the Company, the Trustee or the Certificate
Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the
<PAGE>



<PAGE> 323

Company, the Trustee, the Certificate Registrar nor any such
agent shall be affected by notice to the contrary.

     [to be used only in the case of the Class IV-A-5
Certificates] [Each Holder of this Certificate hereby agrees for
the benefit of the Certificate Insurer that, to the extent the
Certificate Insurer makes Insured Payments, either directly or
indirectly (as by paying through the Trustee), to the Insured
Certificateholders, the Certificate Insurer will be subrogated to
the rights of the Insured Certificateholders to the extent of
such payments.]

     The obligations created by the Pooling Agreement and the
trust funds created thereby shall terminate upon (i) the later of
the maturity or other liquidation (including repurchase by the
Company) of the last Mortgage Loan remaining in the REMIC I Trust
Fund or the disposition of all property acquired upon foreclosure
or deed in lieu of foreclosure of any Mortgage Loan, and (ii) the
payment to Certificateholders of all amounts held by the Trustee
and required to be paid to them pursuant to the Pooling
Agreement. In the event that the Company repurchases any Mortgage
Loan pursuant to the Pooling Agreement, such Pooling Agreement
generally requires that the Trustee distribute to the
Certificateholders in the aggregate an amount equal to 100% of
the unpaid Principal Balance of such Mortgage Loan, plus accrued
interest at the applicable Pass-Through Rate to the next
scheduled Due Date for the Mortgage Loan. The Pooling Agreement
permits, but does not require, the Company to repurchase from the
REMIC I Trust Fund all Mortgage Loans at the time subject thereto
and all property acquired in respect of any Mortgage Loan upon
payment to the Certificateholders of the amounts specified in the
Pooling Agreement. The exercise of such right will effect early
retirement of the Certificates, the Company's right to repurchase
being subject to the aggregate unpaid Principal Balance of the
Mortgage Loans at the time of repurchase being less than five
percent (5%) of the aggregate unpaid Principal Balance of the
Mortgage Loans as of the Cut-Off Date.

Ladies and Gentlemen:

     This letter is delivered to you in connection with the sale

"Company") and State Street Bank and Trust Company, as trustee
(the "Trustee"). All terms used herein and not otherwise defined
shall have the meanings set forth in the Pooling Agreement. The

covenants with, the Company and the Trustee that:

<PAGE>



<PAGE> 325

     1.   No purpose of the Seller relating to the sale of the
Certificate by the Seller to the Purchaser is or will be to
enable the Seller to impede the assessment or collection of tax.

     2.   The Seller understands that the Purchaser has delivered
to the Trustee and the Company a transferee affidavit and
agreement in the form attached to the Pooling Agreement as
Exhibit J. The Seller does not know or believe that any
representation contained therein is false.

     3.   The Seller has no actual knowledge that the proposed
Transferee is not a Permitted Transferee.

     4.   The Seller has no actual knowledge that the Purchaser
would be unwilling or unable to pay taxes due on its share of the
taxable income attributable to the Certificates.

     5.   The Seller has conducted a reasonable investigation of
the financial condition of the Purchaser and, as a result of the
investigation, found that the Purchaser has historically paid its
debts as they came due, and found no significant evidence to
indicate that the Purchaser will not continue to pay its debts as
they come due in the future.

     6.   The Purchaser has represented to the Seller that, if
the Certificates constitute a noneconomic residual interest, it
(i) understands that as holder of a noneconomic residual interest
it may incur tax liabilities in excess of any cash flows
generated by the interest, and (ii) intends to pay taxes
associated with its holding of the Certificates as they become
due.

                              Very truly yours,

          [NAME OF OFFICER], being first duly sworn, deposes and
          says:
          
          1.   That he is [Title of Officer] of [Name of Owner]
(record or beneficial owner of the Class [R-1][R-2][R-3]
Certificate (the "Owner")), a [savings institution] [corporation]
duly organized and existing under the laws of [the State of
                 ] [the United States], on behalf of which he
makes this affidavit and agreement.

          2.   That the Owner (i) is not and will not be a
"disqualified organization" as of [date of transfer] within the
meaning of Section 860E(e)(5) of the Internal Revenue Code of
1986, as amended (the "Code") and will endeavor to remain other
than a disqualified organization for so long as it retains its
ownership interest in the Class [R-1][R-2] [R-3] Certificates,
and (ii) is acquiring the Class [R-1][R-2] [R-3] Certificates for
its own account or for the account of another Owner from which it
has received an affidavit and agreement in substantially the same
form as this affidavit and agreement. (For this purpose, a
disqualified organization" means the United States, any state or
political subdivision thereof, or any agency or instrumentality
of any of the foregoing (other than an instrumentality all of the
activities of which are subject to tax and, except for the
Federal Home Loan Mortgage Corporation, a majority of whose board
of directors is not selected by any such governmental entity, or
any foreign government or international organization, or any
agency or instrumentality of such foreign government or
organization, any rural electric or telephone cooperative, or any
organization (other than certain farmers' cooperatives) that is
generally exempt from federal income tax unless such organization
is subject to the tax on unrelated business taxable income).

          3.   That the Owner is aware (i) of the tax that would
be imposed on transfers of the Class [R-1][R-2] [R-3]
Certificates after March 31, 1988; (ii) that such tax would be on
the transferor, or, if such transfer is through an agent (which
person includes a broker, nominee or middle-man) for a
disqualified organization, on the agent; (iii) that the person
other-wise liable for the tax shall be relieved of liability for
the tax if the transferee furnishes to such person an affidavit
that the transferee is not a disqualified organization and, at
the time of transfer, such person does not have actual knowledge
that the affidavit is false; and (iv) that the Class [R-1][R-2]
[R-3] Certificates may be a "noneconomic residual interest"
within the meaning of Treasury regulations promulgated pursuant
to the Code and that the transferor of a noneconomic residual
interest will remain liable for any taxes due with respect to the
income on such residual interest, if a significant purpose of the
transfer was to enable the transferor to impede the assessment or
collection of tax.

<PAGE>



<PAGE> 327

          4.   That the Owner is aware of the tax imposed on a
"pass-through entity" holding the Class [R-1][R-2] [R-3]
Certificates if at any time during the taxable year of the pass-
through entity a disqualified organization is the record holder
of an interest in such entity. (For this purpose, a "pass through
entity" includes a regulated investment company, a real estate
investment trust or common trust fund, a partnership, trust or
estate, and certain cooperatives.)

          5.   That the Owner is aware that the Trustee will not
register the Transfer of the Class [R-1][R-2] [R-3] Certificates
unless the transferee, or the transferees' agent, delivers to it
an affidavit and agreement, among other things, in substantially
the same form as this affidavit and agreement. The Owner
expressly agrees that it will not consummate any such transfer if
it knows or believes that any of the representations contained in
such affidavit and agreement are false.

          6.   That the Owner has reviewed the restrictions set
forth on the face of the Class [R-1][R-2] [R-3] Certificates and
the provisions of Section 5.01 of the Pooling Agreement under
which the Class [R-1][R-2] [R-3] Certificates were issued (in
particular, clauses (iii)(A) and (iii)(B) of Section 5.01(c)
which authorize the Trustee to deliver payments to a person other
than the Owner and negotiate a mandatory sale by the Trustee in
the event the Owner holds such Certificates in violation of
Section 5.01). The Owner expressly agrees to be bound by and to
comply with such restrictions and provisions.

          7.   That the Owner consents to any additional
restrictions or arrangements that shall be deemed necessary upon
advice of counsel to constitute a reasonable arrangement to
ensure that the Class [R-1][R-2] [R-3] Certificates will only be
owned, directly or indirectly, by an Owner that is not a
disqualified organization.

          8.   The Owner's Taxpayer Identification Number is
                               .

          9.   That no purpose of the Owner relating to the
purchase of the Class [R-1][R-2] [R-3] Certificates by the Owner
is or will be to enable the transferor to impede the assessment
or collection of tax.

          10.  That the Owner has no present knowledge or
expectation that it will be unable to pay any United States taxes
owed by it so long as any of the Certificates remain outstanding.

          11.  That the Owner has no present knowledge or
expectation that it will become insolvent or subject to a
bankruptcy proceeding for so long as any of the Certificates
remain outstanding.
<PAGE>



<PAGE> 328


          12.  That no purpose of the Owner relating to any sale
of the Class [R-1][R-2] [R-3] Certificates by the Owner will be
to impede the assessment or collection of tax.

          13.  The Owner is a citizen or resident of the United
States, a corporation, partnership or other entity created or
organized in, or under the laws of, the United States or any
political subdivision thereof, or an estate or trust whose income
from sources without the United States is includible in gross
income for United States federal income tax purposes regardless
of its connection with the conduct of a trade or business within
the United States.

          14.  The Owner hereby agrees to cooperate with the
Company and to take any action required of it by the Code or
Treasury regulations thereunder (whether now or hereafter
promulgated) in order to create or maintain the REMIC status of
the REMIC I Trust Fund, the REMIC II Trust Fund and the REMIC III
Trust Fund (the "Trust Funds").

          15.  The Owner hereby agrees that it will not take any
action that could endanger the REMIC status of the Trust Funds or
result in the imposition of tax on the Trust Funds unless counsel
for, or acceptable to, the Company has provided an opinion that
such action will not result in the loss of such REMIC status or
the imposition of such tax, as applicable.

          16.  The Owner as transferee of the Class [R-1][R-2] [R-
3] Certificates has represented to their transferor that, if the
Class [R-1][R-2] [R-3] Certificates constitute a noneconomic
residual interest, the Owner (i) understands that as holder of a
noneconomic residual interest it may incur tax liabilities in
excess of any cash flows generated by the interest, and (ii)
intends to pay taxes associated with its holding of the Class [R-
1][R-2] [R-3] Certificates as they become due.

          IN WITNESS WHEREOF, the Owner has caused this
instrument to be executed on its behalf, pursuant to the
authority of its Board of Directors, by its [Title of Officer]
and its corporate seal to be hereunto attached, attested by its
[Assistant] Secretary, this           day of          , 19 __ .

     The undersigned  seller, as registered holder (the
"Seller"), intends to transfer the Rule 144A Securities described
above to the undersigned buyer (the "Buyer").

     1.   In connection with such transfer and in accordance with
the agreements pursuant to which the Rule 144A Securities were
issued, the Seller hereby certifies the following facts: Neither
the Seller nor anyone acting on its behalf has offered,
<PAGE>



<PAGE> 330

transferred, pledged, sold or otherwise disposed of the Rule 144A
Securities, any interest in the Rule 144A Securities or any other
similar security to, or solicited any offer to buy or accept a
transfer, pledge or other disposition of the Rule 144A
Securities, any interest in the Rule 144A Securities or any other
similar security from, or otherwise approached or negotiated with
respect to the Rule 144A Securities, any interest in the Rule
144A Securities or any other similar security with, any person in
any manner, or made any general solicitation by means of general
advertising or in any other manner, or taken any other action,
that would constitute a distribution of the Rule 144A Securities
under the Securities Act of 1933, as amended (the "1933 Act"), or
that would render the disposition of the Rule 144A Securities a
violation of Section 5 of the 1933 Act or require registration
pursuant thereto, and that the Seller has not offered the Rule
144A Securities to any person other than the Buyer or another
"qualified institutional buyer" as defined in Rule 144A under the
1933 Act.

     2.   The Buyer warrants and represents to, and covenants
with, the Seller, the Trustee and the Master Servicer (as defined
in the Pooling and Servicing Agreement (the "Agreement") dated as
of November 1, 1998 between PNC Mortgage Securities Corp., as
Depositor and Master Servicer and State Street Bank and Trust
Company, as Trustee) pursuant to Section 5.01(f) of the
Agreement, as follows:

          a.   The Buyer understands that the Rule 144A
     Securities have not been registered under the 1933 Act or
     the securities laws of any state.
     
          b.   The Buyer considers itself a substantial,

preceding paragraph. Further, in determining such aggregate
amount, the Buyer may have included securities owned by
subsidiaries of the  Buyer,  but only if such subsidiaries are
consolidated with the Buyer in its financial statements prepared

Buyer may be in reliance on Rule 144A.

                              Will the Buyer be purchasing the
Rule 144A

separate account) in reliance on Rule 144A, the Buyer will only
purchase for the account of a third party that at the time is a
"qualified institutional buyer" within the meaning of Rule 144A.
In addition, the Buyer agrees that the Buyer will not purchase
securities for a third party unless the Buyer has obtained a
current representation letter from such third party or taken
other appropriate steps contemplated by Rule 144A to conclude
that such third party independently meets the definition of
"qualified institutional buyer" set forth in Rule 144A.

     7.   The Buyer will notify each of the parties to which this
certification is made of any changes in the information and
conclusions herein. Until such notice is given, the Buyer's
purchase of Rule 144A Securities will constitute a reaffirmation
of this certification as of the date of such purchase.
