PIIIB =   the sum of the Group III Subordinate Balance and  Group V
     Subordinate Balance after the allocation of Realized Losses and

     distributions of principal on such Distribution Date.

PIVB =    the Group IV Subordinate Balance after the allocation of Realized
     Losses and distributions of principal on such Distribution Date.

R =  the Group D-B Certificate Interest Rate = (6.5%PIIIB + 7%PIVB)/(PIIIB
+ PIVB)

Y1 =      the principal balance of the Class Y-1 Regular Interests after
     distributions on the prior Distribution Date.

Y2 =      the principal balance of the Class Y-2 Regular Interests after
     distributions on the prior Distribution Date.

Y3 =      the principal balance of the Class Y-3 Regular Interests after
     distributions on the prior Distribution Date.

DELTAY1 =      the Class Y-1 Principal Reduction Amount.

     Regular Interests after distributions on the prior Distribution Date.

P2 =      the aggregate principal balance of the Class Y-2 and Class Z-2
     Regular Interests after distributions on the prior Distribution Date.

Otherwise, DELTAY1 = DELTAY9 (DELTAP1 /DELTAP9) and DELTAY3 = DELTAY9
(DELTAP3 /DELTAP9).

alpha =   .0005

gamma1 =  (R - 6.5%)/(7% - R).  gamma1 is a non-negative number unless its
     denominator is zero, in which event it is undefined.

If gamma1 is zero, DELTAY2 = Y2 and DELTAY9 = (Y9/P9)DELTAP9.

If gamma1 is undefined, DELTAY9 = Y9, DELTAY2 = (Y2/P2)DELTAP2.

In the remaining situations, DELTAY2 and DELTAY9 shall be defined as
     follows:


1.   If Y2 - alpha(P2 - DELTAP2)  0, Y9- alpha(P9 - DELTAP9)  0, and
  gamma1(P9 - DELTAP9) < (P2 - DELTAP2), DELTAY2 = Y2 - alphagamma1(P9 -
   DELTAP9) and DELTAY9 = Y9 - alpha(P9 - DELTAP9).

2.   If Y2 - alpha(P2 - DELTAP2)  0, Y9 - alpha(P9 - DELTAP9)  0, and
  gamma1(P9 - DELTAP9)  (P2 - DELTAP2), DELTAY2 = Y2 - alpha(P2 - DELTAP2)
  and DELTAY9 = Y9 - (alpha/gamma1)(P2 - DELTAP2).

3.   If Y2 - alpha(P2 - DELTAP2) < 0, Y9 - alpha(P9 - DELTAP9)  0, and
  Y9 - alpha(P9 - DELTAP9)  Y9 - (Y2/gamma1),
  DELTAY2 = Y2 - alphagamma1(P9 - DELTAP9) and
  DELTAY9 = Y9 - alpha(P9 - DELTAP9).

4.   If Y2 - alpha(P2 - DELTAP2) < 0, Y9 - (Y2/gamma1)  0, and
  Y9 - alpha(P9 - DELTAP9)  Y9 - (Y2/gamma1), DELTAY2 = 0 and
  DELTAY9 = Y9 - (Y2/gamma1).

5.   If Y9 - alpha(P9 - DELTAP9) < 0, Y9 - (Y2/gamma1) < 0, and
  Y2 - alpha(P2 - DELTAP2)  Y2 - (gamma1Y9), DELTAY2 = Y2 - (gamma1Y9) and
  DELTAY9 = 0.

6.   If Y9 - alpha(P9 - DELTAP9) < 0, Y2 - alpha(P2 - DELTAP2)  0, and
  Y2 - alpha(P2 - DELTAP2)  Y2 - (gamma1Y9),
  DELTAY2 = Y2 - alpha(P2 - DELTAP2) and
  DELTAY9 = Y9 - (alpha/gamma1)(P2 - DELTAP2).

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 Y2 to Y9 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 Z-1 Class Z-2 and Class Z-3 Regular Interests
<PAGE>



<PAGE> 22

     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 and 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 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 Y2 and whose
     denominator is the sum of Y2 and the Class Z-2 Principal Balance and (b)
     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 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 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 DELTAY9 between
DELTAY1 and DELTAY3 cannot be achieved because either DELTAY1 as so defined
is greater than DELTAP1 or DELTAY3 as so defined is greater than DELTAP3,
such an allocation shall be made as close as possible to the formula
allocation within the requirement that DELTAY1 < DELTAP1 and DELTAY3 <
DELTAP3.

     To calculate the initial balances for the Class Y-1, Class Y-2, Class
Y-3, Class Z-1, Class Z-2 and Class Z-3 Regular Interests, first calculate
the Group III, Group IV and Group V Subordinate Balances as of the Cut Off
Date.  Then calculate R according to the definition above.  Calculate
gamma1 according to the definition above.  Calculate P1, P2 and P3 as of
the Cut-Off Date as the aggregate Class Principal Balance of the Group III
Certificates reduced by the Class III-P Principal Balance and the Class R-1
Principal Balance, the aggregate Class Principal Balance of the Group IV
Certificates reduced by the Class IV-P Principal Balance, and the aggregate
Class Principal Balance of the Group V Certificates reduced by the Class V-
P Principal Balance, respectively.

If 0.0005 gamma1 (P1 + P3)  0.0005 P2, Y1 = 0.0005 P1, Y3 = 0.0005 P3, and
Y2 = 0.0005 gamma1 (P1 + P3).

If 0.0005 gamma1 (P1 + P3) > 0.0005 P2, Y2 = 0.0005 P2,
Y1 = 0.0005 P2 P1/gamma1 (P1 + P3) and Y3 = 0.0005 P2 P3/gamma1 (P1 + P3).

If 0.0005 gamma1 (P1 + P3)  0.0005 P2, Y1 = 0.0005 P1, Y3 = 0.0005 P3, and
Y2 = 0.0005 gamma1 (P1 + P3).

If 0.0005 gamma1 (P1 + P3) > 0.0005 P2, Y2 = 0.0005 P2,
Y1 = 0.0005 P2 P1/gamma1 (P1 + P3) and Y3 = 0.0005 P2 P3/gamma1 (P1 + P3).

If 0.0005 gamma1 (P1 + P3)  0.0005 P2, Y1 = 0.0005 P1, Y3 = 0.0005 P3, and
Y2 = 0.0005 gamma1 (P1 + P3).

If 0.0005 gamma1 (P1 + P3) > 0.0005 P2, Y2 = 0.0005 P2,
Y1 = 0.0005 P2 P1/gamma1 (P1 + P3) and Y3 = 0.0005 P2 P3/gamma1 (P1 + P3).

Then Z1 = P1 - Y1, Z2 = P2 - Y2 and Z3 = P3 - Y3.

Regular Interests.

     Class Z Principal Reduction Amounts: For any Distribution Date, the
amounts by which the Class Principal Balances of the Class Z-1, Class Z-2

the excess of the REMIC I Available Distribution Amount for the related
Loan Group (i.e. the "related Loan Group" for the Class Z-1 Regular
Interests is Loan Group III, the "related Loan Group" for the Class Z-2
Regular Interests is Loan Group IV and the "related Loan Group" for the
Class Z-3 Regular Interests is Loan Group V) over the sum of the amounts
thereof distributable (i) to the related Class P-M Regular Interests, (ii)
to the related Class X-M Regular Interests, (iii) in respect of interest on
the related Class Y and Class Z Regular Interests and (iv) to the Class R-1
Certificates (in the case of Loan Group III) and (y) the excess of the
Realized Losses allocable to principal for the related Loan Group over the
portion of such Realized Losses allocable to the related Class P-M Regular
Interests over (B) the Class Y Principal Reduction Amount for the related

                         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 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

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 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 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 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
<PAGE>



<PAGE> 95

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 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
<PAGE>



<PAGE> 96

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." Notwithstanding the immediately preceding sentence, in the event
that the Company causes any Mortgage Loan to be delivered to the Trustee by
a custodian which is not an affiliate of the Company and the related
Mortgage File does not contain an assignment of the Mortgage as required by
clause (iii)(1) or clause (iii)(2) of the definition of "Mortgage File,"
the Company shall cause such custodian promptly to deliver such an
assignment, but in no event later than 30 days after the Closing Date.  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 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.

<PAGE>



<PAGE> 97

     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.

     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 tax laws; (b) make an election, on behalf
<PAGE>



<PAGE> 98

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.

     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
<PAGE>



<PAGE> 99

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 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
<PAGE>

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.
Notwithstanding anything herein to the contrary, each Substitute Mortgage
Loan shall be deemed to have the same Pass-Through Rate as the Mortgage
Loan for which it was substituted.

     The Purchase Price for each repurchased Mortgage Loan 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.

<PAGE>



<PAGE> 105

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 shall be
accomplished in the manner and at the Purchase 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
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
<PAGE>



<PAGE> 106

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 irrevocably sell, transfer, assign, set over, and otherwise convey
to the Trustee in trust for the benefit of the Holders of the Certificates
(other than the Class R-1 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
Certificates (other than the Class R-1 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 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

     Certificate Insurance 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, 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 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
<PAGE>



<PAGE> 108

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

REMIC II 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 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
<PAGE>



<PAGE> 109

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 Certificates (other than the Class R-1 Certificates).  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 II Trust Fund, the
Certificates (other than the Class R-1 Certificates) in Authorized
Denominations evidencing the entire ownership interest in the REMIC II
Trust Fund.

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



<PAGE> 110

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, 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, 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. 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
<PAGE>



<PAGE> 111

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 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 either 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
<PAGE>



<PAGE> 112

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 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 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 Investments.(a)  Not later
than the Withdrawal Date, the Master Servicer shall withdraw or direct the
<PAGE>



<PAGE> 113

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 invested 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.

     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
<PAGE>



<PAGE> 114

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 by the Master Servicer
pursuant to Section 4.02 of this Agreement and any Insurance Proceeds or
Liquidation Proceeds (including amounts paid by the Company in respect of
any 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 into the Certificate Account amounts received under the
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:

          (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;
<PAGE>



<PAGE> 115

     
          (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 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;
<PAGE>



<PAGE> 116

     
     (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 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 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 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 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
<PAGE>



<PAGE> 117

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, 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. 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 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.

<PAGE>



<PAGE> 118

     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 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 D-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
<PAGE>



<PAGE> 119

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
connection with a default or imminent default of a Mortgage Loan, such
property shall be disposed of by the Master Servicer within three 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 three 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
<PAGE>



<PAGE> 120

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 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 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
<PAGE>



<PAGE> 121

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, the Trustee shall, upon
request of the Master Servicer and delivery to it of a trust receipt signed
by a Servicing 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 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,
<PAGE>



<PAGE> 122

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 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 3.19.  [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 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.  [Reserved].

     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 noon, 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
<PAGE>



<PAGE> 124

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 Holders of
the Insured Certificates 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 Holder
of an Insured Certificate any Insured Payment delivered to it by the
Certificate Insurer and (ii) distribute such Insured Payment to such Holder
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
Holders.  The Trustee hereby agrees on behalf of each Holder of an Insured
Certificate (and each such Holder, 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 Holder of
an Insured Certificate, 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 II Distribution Amount (as notified to the Trustee by
the Master Servicer in the written statement required pursuant to Section
3.22).

     (d)  On each Distribution Date and prior to making any distributions
on such Distribution Date pursuant to Section 4.01 or Section 4.04, the
Trustee shall withdraw from the Certificate Account and pay to the
Certificate Insurer the Certificate Insurer Premium as set forth in the
statement delivered to the Trustee pursuant to Section 4.02(b).

     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 to the Class R-1 Certificateholders the sum of (a)
<PAGE>



<PAGE> 125

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 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 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 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.
<PAGE>



<PAGE> 126


     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 Distribution
Amount, the Deficiency Amount, if any, to be paid by the Certificate
Insurer 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 and each Class of Certificates on such
Distribution Date (such amounts to be determined in accordance with the
definitions of "REMIC I Distribution Amount" and "REMIC II Distribution
Amount," Section 4.01 and Section 4.04 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
<PAGE>



<PAGE> 127

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 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 Master Servicer or
such Servicer shall determine would be a Nonrecoverable Advance, and (b)
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 Certificateholders.

     (a)  On each Distribution Date, the Trustee (or any duly appointed
paying agent) shall withdraw from the Certificate Account, (i) the REMIC II
Available Distribution Amount for such Distribution Date and shall
distribute, from the amount so withdrawn, to the extent of the REMIC II
Available Distribution Amount, the REMIC II Distribution Amount to the
Certificates (other than the Class R-1 Certificates) and to the Certificate
Insurer in respect of the Certificate Insurer's subrogation to certain
rights to payment due to the Holders of the Insured Certificates as set
forth in Section 3.22 and (ii) the Deficiency Amount, if any, from the
Certificate Account and distribute such amount to the Holders of the
Insured Certificates, 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, 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 4.04(c)(ii) and Section 9.01(b).
<PAGE>



<PAGE> 128


     (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 4.05.  Statements to Certificateholders. With each 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 Special Hazard Coverage for Loan Group I
     and Loan Group II and the amount of the Special Hazard Coverage for
     Loan Group III, Loan Group IV and Loan Group V available to the Senior
     Certificates remaining as of the close of business on the applicable
<PAGE>



<PAGE> 129

     Determination Date;

     (c)  Restrictions on Transfers of the Residual Certificates to
Disqualified Organizations are set forth in 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 "Transferee Affidavit and
<PAGE>



<PAGE> 131

          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 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
<PAGE>



<PAGE> 132

     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 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 and REMIC II to
          cease to qualify as a REMIC and will not create a risk that (1)
          REMIC I and REMIC II 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
          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

     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] 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.

     CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE PROVISIONS OF
<PAGE>

     THIS PARAGRAPH.

     II, 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 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 transfer, and that the Certificateholder's proposed
<PAGE>



<PAGE> 135

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 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.

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

registration 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

     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
<PAGE>



<PAGE> 137

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 II Trust Fund (or with
respect to the Class R-1 Certificates, the residual ownership interests in
the REMIC I Trust Fund) 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
<PAGE>

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 Company 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
     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
<PAGE>



<PAGE> 139

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-
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 5.10.  Office for Transfer of Certificates. The Trustee shall
maintain in Massachusetts and in New York, New York, an office or agency
where Certificates may be surrendered for registration of transfer or
exchange. The Corporate Trust Office and State Street Bank and Trust
Company, N.A., 61 Broadway, New York, NY 10006, Attention: Corporate Trust
Window are initially designated for said purposes.

                    The Company and the Master Servicer
                                     
     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..

Servicer. Any corporation into which the Company or the Master Servicer may
be merged or consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Company or the Master Servicer
shall be a party, or any corporation succeeding to the business of the
Company or the Master Servicer, shall be the 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

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, employee or agent of the Company or the Master Servicer may rely
in good faith on any document of any kind properly executed and submitted

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. 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

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
<PAGE>



<PAGE> 141

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 Resign. The
Company shall not resign from the obligations 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 longer permissible under applicable law. Any successor 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 under this
Agreement.

     Section 6.05.  Trustee Access. The Master Servicer shall afford the
Depositor and the Trustee, upon reasonable notice, during normal business
hours access to all records maintained by the Master Servicer, in respect
of its rights and obligations hereunder and access to such of its officers
as are responsible for such obligations.  Upon reasonable request, the
Master Servicer, shall furnish the Company and the Trustee with its most
recent financial statements (or, for so long as the Company is the Master
Servicer, the most recent consolidating financial statements for the
Company 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.

                                  Default
                                     
     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
<PAGE>



<PAGE> 142

     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  II
     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 II Trust Fund; or

           (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
II  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
<PAGE>



<PAGE> 143

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 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, subject to the last
sentence of this paragraph, 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 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
<PAGE>



<PAGE> 144

          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 II 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 II 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.

     (c)  In any circumstances in which this Agreement states that
Certificateholders owning Certificates evidencing a certain percentage
Percentage Interest in the REMIC II 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
<PAGE>



<PAGE> 145

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 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.

                               ARTICLE VIII
                                     
                          Concerning the Trustee
                                     
     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.
<PAGE>



<PAGE> 146


     (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 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 II 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 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 II 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
<PAGE>



<PAGE> 148

     Section 10.06; and
     
          (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 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 or
<PAGE>



<PAGE> 149

the REMIC II 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 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 II 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.

<PAGE>



<PAGE> 150

     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 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 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
<PAGE>



<PAGE> 151

act as co-trustee or co-trustees, jointly with the Trustee, or separate
trustee or separate trustees, of all or any part of the Trust Fund and to
vest in such Person or Persons, in such capacity, such title to the 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 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 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 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.

     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(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
<PAGE>



<PAGE> 153

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 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.

                                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
<PAGE>



<PAGE> 154

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 them
hereunder and the payment to the Certificate Insurer of any remaining
amounts pursuant to the priority set forth in the definition of "REMIC II
Distribution Amount" of the Class III-A-2 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.
<PAGE>



<PAGE> 155


     (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 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 appropriate steps to
contact the remaining Certificateholders concerning surrender of their
Certificates, and the cost thereof shall be paid out of the funds and other
assets which remain in trust hereunder.

     Section 9.02.  Additional Termination Requirements.

     (a)  In the event the Company exercises its purchase option as
provided in Section 9.01, the REMIC I Trust Fund and the REMIC II 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 and REMIC II 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 and the REMIC II Trust Fund as described in Section 860F of the Code,
or (ii) cause the REMIC I Trust Fund or the REMIC II 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 and the REMIC II 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 and the REMIC II Trust Fund; and
     
          (ii) At or after the time of adoption of such a plan of complete
<PAGE>



<PAGE> 156

     liquidation and at or prior to the final Distribution Date, the Master
     Servicer as agent of the Trustee shall sell all of the assets of the
     REMIC I Trust Fund and the REMIC II 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.

     Section 9.03.  Trusts Irrevocable. Except as expressly provided herein, the
trusts created hereby are irrevocable.

                                 ARTICLE X
                                     
                         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 Holders of the Insured Certificates: (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
Trust Fund, or to assure the conveyance to the Trustee of any property
included in the 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 REMIC II 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
<PAGE>



<PAGE> 157

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 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 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 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
or the REMIC II 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
<PAGE>



<PAGE> 158

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 II 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 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 Holders of the Insured
Certificates 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
<PAGE>



<PAGE> 159

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 accountable by reason of the disclosure of
any such information as to the names and addresses of the
Certificateholders hereunder, regardless of the source from which such
information was derived.

     Section 10.05. Governing Law. This Agreement shall be construed in
accordance with the laws of the State of New York and the obligations,
rights and remedies of the parties hereunder shall be determined in
accordance with such laws without giving effect to conflict of laws
principles.

Evidencing a Percentage Interest in a trust fund whose assets consist of
interests in another trust fund whose assets consists of, among other
things, a pool of conventional one- to four-family mortgage loans formed
and administered by

                       PNC MORTGAGE SECURITIES CORP.
                                     
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 December
24, 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 Company 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 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.

     This Certificate does not represent an obligation of or interest in
PNC Mortgage Securities Corp. or any of its affiliates, including PNC Bank
Corp. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed by any agency or instrumentality of the United States.

     This certifies that the above-named Registered Owner is the registered

assets consist of, among other things, a pool (the "Mortgage Pool") of
conventional one- to four-family mortgage loans (the "Mortgage Loans"),
formed and administered by PNC Mortgage Securities Corp. (the "Company"),
which term includes any successor entity under the Pooling Agreement
referred to below. The Mortgage Pool was created pursuant to a Pooling and
Servicing Agreement, dated as of the Cut-Off Date stated above (the
"Pooling Agreement"), between the Company and State Street Bank and Trust
Company, as Trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the meanings assigned in the
Pooling Agreement. Nothing herein shall be deemed inconsistent with such
meanings, and in the event of any conflict between the Pooling Agreement
and the terms of this Certificate, the Pooling Agreement shall control.
This Certificate is issued under and is subject to the terms, provisions
and conditions of the Pooling Agreement, to which Pooling Agreement the
Holder of this Certificate, by virtue of the acceptance hereof, assents and
by which such Holder is bound.

Business Day immediately following (the "Distribution Date"), commencing on
the first Distribution Date specified above, to the Person in whose name
this Certificate is registered at the close of business on the last day (or
if such last day is not a Business Day, the Business Day immediately
preceding such last day) of the month immediately preceding the month of
such distribution (the "Record Date"), to the extent of 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 Certificates of this Class, as
specified in Section 4.01 of the Pooling Agreement.

     Distributions on this Certificate will be made by the Trustee by wire
transfer or check mailed to the address of the Person entitled thereto, as
such name and address shall appear on the Certificate Register.
Notwithstanding the above, the final distribution on this Certificate will
be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate
to the Certificate Registrar.

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

     Unless the certificate of authentication hereon has been executed by
or on behalf of the Trustee, by manual signature, this Certificate shall
not be entitled to any benefit under the Pooling Agreement or be valid for
any purpose.

     IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly
executed.

                       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 II 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 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
<PAGE>



<PAGE> 214

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 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
<PAGE>



<PAGE> 215

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.

                                WITNESSETH:
                                     
      WHEREAS, this Company wishes to sell first lien residential  mortgage
loans  to, and service first lien residential mortgage loans on behalf  of,
PNC Mortgage; and

      WHEREAS,  the  Company  has  submitted a Seller  Application  to  PNC
Mortgage and has been approved by PNC Mortgage for participation in the PNC
Mortgage Purchase Programs; and

      WHEREAS,  the  Company  has received and reviewed  the  PNC  Mortgage
Purchase  Programs Seller Guide (the "Seller Guide"), as well  as  the  PNC
Mortgage  Servicing  Guide (the "Servicing Guide" and,  together  with  the
Seller  Guide,  the  "Guides"), and understands each  and  every  provision
thereof;

      NOW,  THEREFORE, in consideration of the premises and of  the  mutual
agreements herein contained, PNC Mortgage and the Company hereby  agree  as
follows:

      1.    Guides.   The Guides, which set forth the terms and  conditions
under  which  PNC Mortgage may elect to purchase mortgage  loans  from  the
Company,  and  the Company shall service mortgage loans on  behalf  of  PNC
Mortgage,  are a supplement to this Agreement and such Guides,  as  may  be
amended or supplemented from time to time by PNC Mortgage, are incorporated
into this Agreement in full by reference and made a part hereof as fully as
if  set forth at length herein.  All capitalized terms used and not defined
herein have the meanings ascribed to them in the Guides.

      2.    Company's  Duties.   The Company shall diligently  perform  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 account, but in no  event  shall
the  Company  exercise less care 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.

      3.    Representations,  Warranties  and  Covenants  of  the  Company;
Remedies of PNC Mortgage.  With respect to each mortgage loan sold  by  the
Company  to  PNC  Mortgage pursuant to the terms  of  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
<PAGE>



<PAGE> 217

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 subject to this Agreement, as well as the

Purchaser hereby acknowledges and agrees as follows:

          Section 1. Definitions. Each capitalized term used herein and not
otherwise defined herein shall have the meaning ascribed to it in the
Pooling and Servicing Agreement, dated as of December 1, 1998 (the "Pooling
Agreement"), by and between PNC Mortgage Securities Corp. ("PNC") and State
Street Bank and Trust Company, as trustee (the "Trustee"), of the PNC
Mortgage Securities Corp. Mortgage Pass-Through Certificates, Series 1998-
14.

          Section 2. Representations and Warranties of the Purchaser. In
connection with the proposed transfer, the Purchaser represents and
warrants to PNC and the Trustee that:

          (a)  The Purchaser is duly organized, validly existing and in
good standing under the laws of the jurisdiction in which the Purchaser is
organized, is authorized to invest in the Purchased Certificates, and to
enter into this Agreement, and duly executed and delivered this Agreement;

          (b)  The Purchaser is acquiring the Purchased Certificates for
its own account as principal and not with a view to the distribution
thereof, in whole or in part;

          (c)  The Purchaser is an "accredited investor" as such term is
defined in paragraph (a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) of Section

          (d)  The Purchaser is not affiliated with the Trustee;

          (e)  The Purchaser confirms that PNC has made available to the

          (g)  The Purchaser will provide the Trustee and the Master
Servicer with affidavits substantially in the form of Exhibit A attached
hereto.

          Section 3.Transfer of Purchased Certificates.

          (a)  The Purchaser understands that the Purchased Certificates
have not been registered under the Act, or any state securities laws and
that no transfer may be made unless the Purchased Certificates are
registered under the Act and under applicable state law or unless an
exemption from registration is available. The Purchaser further understands
that neither PNC nor the Trust Funds are under any obligation to register
the Purchased Certificates or make an exemption available. In the event
that such a transfer is to be made within two years from the Closing Date
without registration under the Act or applicable state securities laws, (i)
the Trustee shall require, in order to assure compliance with such laws,
that the Certificateholder's prospective transferee each certify to PNC and
the Trustee as to the factual basis for the registration or qualification
exemption relied upon, and (ii) the Trustee or PNC may require an Opinion
of Counsel that such transfer may be made pursuant to an exemption from the
Act and state securities laws, which Opinion of Counsel shall not be an
expense of the Trustee or PNC. Any such Certificateholder desiring to
effect such transfer shall, and does hereby agree to, indemnify the Trustee
and PNC 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.

          (b)  No transfer of a Purchased Certificate shall be made unless
the transferee provides PNC and the Trustee with (i) a Transferee's
Agreement, substantially in the form of this Agreement, and (ii) either (a)
an affidavit substantially in the form of Exhibit A hereto that the
proposed transferee (x) is not an employee benefit plan or other plan or
arrangement subject to the prohibited transaction provisions of ERISA or
Section 4975 of the Internal Revenue Code of 1986, as amended, or
comparable provisions of any subsequent enactments (a "Plan"), a trustee of
any Plan, or any other Person who is using the "plan assets" of any Plan to
effect such acquisition or (y) is an insurance company, the source of funds
to be used by it to purchase the Purchased Certificates is an "insurance
company general account" (within the meaning of Department of Labor
Prohibited Transaction Class Exemption ("PTCE") 95-60), and the purchase is
being made in reliance upon the availability of the exemptive relief
afforded under Sections I and III of PTCE 95-60, or (b) a Benefit Plan
Opinion (as defined in Exhibit A hereto).

          (c)  The Purchaser acknowledges that its Purchased Certificates
bear a legend setting forth the applicable restrictions on transfer.

          IN WITNESS WHEREOF, the undersigned has caused this Agreement to
be validly executed by its duly authorized representative as of the day and
the year first above written.

behalf of which I have the authority to make this affidavit.

          2.   That the Purchaser is acquiring a Purchased Certificate
representing an interest in the Trust Funds.

          3.   That the Purchaser (i) is not an employee benefit plan or
other plan or arrangement subject to the prohibited transaction provisions
of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), or Section 4975 of the Internal Revenue Code of 1986, as amended
(the "Code"), or comparable provisions of any subsequent enactments (a
"Plan"), a trustee of any Plan, or any other Person who is using the "plan
assets" of any Plan to effect such acquisition, (ii) has provided a
"Benefit Plan Opinion" satisfactory to PNC Mortgage Securities Corp. (the
"Company") and the Trustee of the Trust Funds or (iii) is an insurance
company, the source of funds to be used by it to purchase the Purchased

of Department of Labor Prohibited Transaction Class Exemption ("PTCE") 95-
60), and the purchase is being made in reliance upon the availability of
the exemptive relief afforded under Sections I and III of PTCE 95-60. A
Benefit Plan Opinion is an opinion of counsel to the effect that the
proposed transfer (a) is permissible under applicable law, (b) will not
constitute or result in a non-exempt prohibited transaction under Section
406 of ERISA or Section 4975 of the Code, and (c) 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
Benefit Plan Opinion shall not be an expense of the Trustee, the Master
Servicer or the Company.

     This Certificate does not represent an obligation of or interest in
PNC Mortgage Securities Corp. or any of its affiliates, including PNC Bank
Corp. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed by any agency or instrumentality of the United States.

     This certifies that the above-named Registered Owner is the registered

whose assets consist of, among other things, a pool (the "Mortgage Pool")
of conventional one- to four-family mortgage loans (the "Mortgage Loans"),

which term includes any successor entity under the Pooling Agreement

provisions of which is set forth hereafter. To the extent not defined

This Certificate is issued under and is subject to the terms, provisions
and conditions of the Pooling Agreement, to which Pooling Agreement the
Holder of this Certificate, by virtue of the acceptance hereof, assents and
by which such Holder is bound.

     Distributions will be made, pursuant to the Pooling Agreement, on the
25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing on

the first Distribution Date specified above, to the Person in whose name
this Certificate is registered at the close of business on the last day (or
if such last day is not a Business Day, the Business Day immediately
preceding such last day) of the month immediately preceding the month of
such distribution (the "Record Date"), to the extent of such
Certificateholder's Percentage Interest represented by this Certificate in
the portion of the REMIC II Available Distribution Amount for such
Distribution Date then distributable on the Certificates of this Class, as
specified in Section 4.04 of the Pooling Agreement.

     Distributions on this Certificate will be made by the Trustee by wire
transfer or check mailed to the address of the Person entitled thereto, as
such name and address shall appear on the Certificate Register.
Notwithstanding the above, the final distribution on this Certificate will
be made after due notice by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate
to the Certificate Registrar.

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

     Unless the certificate of authentication hereon has been executed by
or on behalf of the Trustee, by manual signature, this Certificate shall
not be entitled to any benefit under the Pooling Agreement or be valid for
any purpose.

     IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly
executed.

                       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 II 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 II 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 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.

<PAGE>



<PAGE> 226

     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 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.

     [to be used only in the case of the Class III-A-2 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
Holders of the Insured Certificates, the Certificate Insurer will be
subrogated to the rights of such Holder 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.

     Re:  PNC Mortgage Securities Corp. Mortgage Pass-Through
          Certificates, Series 1998-14, Class [R-1] [R-2]
          
Ladies and Gentlemen:

     This letter is delivered to you in connection with the sale from
(the "Seller") to                  (the "Purchaser") of
$____________________ initial Certificate Principal Balance of Mortgage
Pass-Through Certificates, Series 1998-14, Class [R-1][R-2] (the
"Certificate"), pursuant to Section 5.01 of the Pooling and Servicing
Agreement (the "Pooling Agreement"), dated as of December 1, 1998 among PNC
Mortgage Securities Corp., as depositor and master servicer (the "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 Seller hereby certifies, represents and
warrants to, and covenants with, the Company and the Trustee that:

     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
<PAGE>



<PAGE> 229

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,

COUNTY OF      )



          [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] 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]
Certificates, and (ii) is acquiring the Class [R-1][R-2] 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] 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] 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.

          4.   That the Owner is aware of the tax imposed on a "pass-
through entity" holding the Class [R-1][R-2] 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] 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] Certificates and the provisions of Section
5.01 of the Pooling Agreement under which the Class [R-1][R-2] 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]
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
                               .
<PAGE>



<PAGE> 231


          9.   That no purpose of the Owner relating to the purchase of the
Class [R-1][R-2] 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.

          12.  That no purpose of the Owner relating to any sale of the
Class [R-1][R-2] 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 and the REMIC II 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] Certificates
has represented to their transferor that, if the Class [R-1][R-2]
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] 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, 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 December 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, sophisticated
     institutional investor having such knowledge and experience in
     financial and business matters that it is capable of evaluating the
     merits and risks of investment in the Rule 144A Securities.
     
          c.   The Buyer has received and reviewed the Private Placement
     Memorandum dated as of December __, 1998 relating to the Rule 144A
     Securities and has been furnished with all information regarding the
     Rule 144A Securities that it has requested from the Seller, the
     Trustee, the Company or the Master Servicer.
     
          d.   Neither the Buyer nor anyone acting on its behalf has
     offered, 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
<PAGE>



<PAGE> 234

     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 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, nor will it
     act, nor has it authorized or will it authorize any person to act, in
     such manner with respect to the Rule 144A Securities.
     
          e.   The Buyer is a "qualified institutional buyer" as that term

     either of the forms of certification to that effect attached hereto as
     Annex 1 or Annex 2, or (2) obtained the waiver of the Company with
     respect to Annex 1 and Annex 2 pursuant to Section 5.01(f) of the
     Agreement. The Buyer is aware that the sale to it is being made in
     reliance on Rule 144A. The Buyer is acquiring the Rule 144A Securities
     for its own account or the accounts of other qualified institutional
     buyers, understands that such Rule 144A Securities may be resold,
     pledged or transferred only (i) to a person reasonably believed to be

     given that the resale, pledge or transfer is being made in reliance on
     Rule 144A, or (ii) pursuant to another exemption from registration
     under the 1933 Act.
     
          f.   The Buyer is not affiliated with (i) the Trustee or (ii) any

     comply, with the guidelines established by Thrift Bulletin 12 issued
     December 13, 1988, by the Office of Regulatory Activities of the
     Federal Home Loan Bank System.
     
     [Required only in the case of a transfer of a Class B Certificate] [3.
The Buyer warrants and represents to, and covenants with, the Trustee, the
Master Servicer and the Company that (1) the Buyer is not an employee
benefit plan (within the meaning of Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")), subject to the

that, in connection with any purchase of securities sold to the Buyer for
the account of a third party (including any 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.
