                         POOLING AND SERVICING AGREEMENT
                         -------------------------------

                  Pooling and Servicing Agreement dated as of May 1, 1998, among
Structured Asset Mortgage Investments Inc., a Delaware corporation, as the
seller (the "Seller"), EMC Mortgage Corporation, a Delaware corporation ("EMC"),
as master servicer (the "Master Servicer"), and State Street Bank and Trust
Company, a Massachusetts trust company, as trustee (the "Trustee").


                              PRELIMINARY STATEMENT

                  On or prior to the Closing Date, the Seller has acquired the
Mortgage Loans from Bear Stearns Mortgage Capital Corporation ("BSMCC"). On the
Closing Date, the Seller will sell the Mortgage Loans and certain other property
to the Trust Fund and receive in consideration therefor Certificates evidencing
the entire beneficial ownership interest in the Trust Fund. EMC will be the
Master Servicer for the Mortgage Loans.

                  The Trustee shall make an election for the assets constituting
REMIC II to be treated for federal income tax purposes as a REMIC. On May 29,
1998 (the "Startup Day"), all the Classes of Regular Certificates will be
designated "regular interests" in such REMIC and the Class R-2 Certificate will
be designated the sole "residual interest" in such REMIC.

                  The Trustee shall make an election for the assets constituting
REMIC I to be treated for federal income tax purposes as a REMIC. On the Startup
Day, all the Classes of Certificates except for the Class R-1 and Class R-2
Certificates will be designated "regular interests" in such REMIC and the Class
R-1 Certificates will be designated the sole "residual interest" in such
REMIC.

                  The Mortgage Loans will have an Outstanding Principal Balance
as of the Cut-off Date, after deducting all Scheduled Principal due on or before
the Cut-off Date, of $283,575,286.60. The initial principal amount of the
Certificates will not exceed such Outstanding Principal Balance.

                  In consideration of the mutual agreements herein contained,
the Seller, the Master Servicer and the Trustee agree as follows:

                                   Definitions

                  Whenever used in this Agreement, the following words and
phrases, unless otherwise expressly provided or unless the context otherwise
requires, shall have the meanings specified in this
Article.

                  ACCOUNT:  The Custody Account, the Certificate Account 
(including each subaccount thereof), the Protected Accounts or the Servicing
Accounts as the context may require.

                  ACCRUED CERTIFICATE INTEREST: For any Certificate for any
Distribution Date, the interest accrued during the related Interest Accrual
Period at the applicable Pass-Through Rate on the Current Principal Amount of
such Certificate immediately prior to such Distribution Date, calculated on the
basis of a 360-day year consisting of twelve 30-day months, less (i) in the case
of a Senior Certificate, such Certificate's share of any Net Interest Shortfall
and Deferred Interest and, after the Cross-Over Date, the interest portion of
any Realized Losses and (ii) in the case of a Subordinate Certificate, such
Certificate's share of any Deferred Interest, Net Interest Shortfall and the
interest portion of any Realized Losses.

                  ADVANCING DATE:  The Business Day preceding the related
Distribution Date.

                  AFFILIATE: As to any Person, any other Person controlling,
controlled by or under common control with such Person. "Control" means the
power to direct the management and policies of a Person, directly or indirectly,
whether through ownership of voting securities, by contract or otherwise.
"Controlled" and "Controlling" have meanings correlative to the foregoing. The
Trustee may conclusively presume that a Person is not an Affiliate of another
Person unless a Responsible Officer of the Trustee has actual knowledge to the
contrary.

                  AGREEMENT:  This Pooling and Servicing Agreement and all 
amendments hereof and supplements hereto.

                  (b) as to any Distribution Date and amounts distributable
         pursuant to clause (ii), (iv) and (v) of the Subordinate Optimal
         Principal Amount, and as to each Class of Subordinate Certificates for

                          Conveyance of Mortgage Loans;
                        Original Issuance of Certificates

                  Section 2.01. CONVEYANCE OF MORTGAGE LOANS TO TRUSTEE. (a) The
Seller concurrently with the execution and delivery of this Agreement, sells,
transfers and assigns to the Trustee without recourse all its right, title and
interest in and to (i) the Mortgage Loans identified in the Mortgage Loan
Schedule, including all interest and principal due with respect to the Mortgage
Loans after the Cut-off Date, but excluding any payments of principal and
interest due on or prior to the Cut-off Date; (ii) such assets as shall from
time to time be credited or are required by the terms of this Agreement to be
credited to the Certificate Account (excluding any income to the Master Servicer
from Permitted Investments under Subsection 4.02(d)), (iii) such assets relating
to the Mortgage Loans as from time to time may be held by the Master Servicer or
a Sub-Servicer in Protected Accounts (excluding any income to the Master
Servicer or any Sub-Servicer from Permitted Investments under Subsection
4.01(a)), (iv) such assets relating to the Mortgage Loans as from time to time
may be held by the Trustee in the Custody Account (excluding any income to the
Master Servicer from Permitted Investments under Section 4.04(d)), (v) any
Servicing Accounts (to the extent the mortgagee has a claim thereto and
excluding any income to the Master Servicer or Sub-Servicer or interest payable
to Mortgagors pursuant to applicable law), (vi) any REO Property, (vii) the
Required Insurance Policies and any amounts paid or payable by the insurer under
any Insurance Policy (to the extent the mortgagee has a claim thereto), (viii)
the Mortgage Loan Purchase Agreement to the extent provided in Subsection
2.04(a), and (ix) any proceeds of the foregoing. Although it is the intent of
the parties to this Agreement that the conveyance of the Seller's right, title
and interest in and to the Mortgage Loans and other assets in the Trust Fund
pursuant to this Agreement shall constitute a purchase and sale and not a loan,
in the event that such conveyance is deemed to be a loan, it is the intent of
the parties to this Agreement that the Seller shall be deemed to have granted to
the Trustee a first priority perfected security interest in all of the Seller's
right, title and interest in, to and under the Mortgage Loans and other assets
in the Trust Fund, and that this Agreement shall constitute a security agreement
under applicable law.

                  (b) In connection with the above transfer and assignment, the
Seller hereby deposits with the Trustee, with respect to each Mortgage Loan, (i)
the original Mortgage Note, endorsed without recourse to the order of the
Trustee and showing an unbroken chain of endorsements from the original payee
thereof to the Person endorsing it to the Trustee, (ii) the original Security
Instrument, which shall have been recorded, with evidence of such recording
indicated thereon, (iii) the assignment (which may be in the form of a blanket
assignment if permitted in the jurisdiction in which the Mortgaged Property is
located) to the Trustee of the Security Instrument, with evidence of recording
with respect to each Mortgage Loan in the name of the Trustee thereon, (iv) all
intervening assignments of the Security Instrument, if applicable and only to
the extent available to the Seller with evidence of recording thereon, (v) the
original or a copy of the policy or certificate of primary mortgage guaranty
insurance, to the extent available, if any, and (vi) originals of all
modification agreements, if applicable and available; PROVIDED, HOWEVER, that in
lieu of the foregoing, the Seller may deliver the following documents, under the
circumstances set forth below: (x) in lieu of the original Security Instrument
or intervening assignments thereof which have been delivered or are being
delivered to recording offices for recording and have not


                                      II-1

<PAGE>



been returned to the Seller in time to permit their delivery as specified above,
the Seller may deliver a true copy thereof with a certification by BSMCC, on the
face of such copy, substantially as follows: "Certified to be a true and correct
copy of the original, which has been transmitted for recording"; (y) in lieu of
the Security Instrument, assignment to the Trustee or intervening assignments
thereof, if the applicable jurisdiction retains the originals of such documents
(as evidenced by a certification from BSMCC to such effect) the Seller may
deliver photocopies of such documents containing an original certification by
the judicial or other governmental authority of the jurisdiction where such
documents were recorded; and (z) in lieu of the Mortgage Notes relating to the
22 Mortgage Loans, with an aggregate Scheduled Principal Balance as of the
Cut-off Date of approximately $1,247,757, each as identified in the list
delivered by the Seller to the Trustee on the Closing Date, the Seller may
deliver a lost note affidavit and, if available, a copy of the original Mortgage
Note; and PROVIDED, FURTHER, HOWEVER, that in the case of Mortgage Loans which
have been prepaid in full after the Cutoff Date and prior to the Closing Date,
the Seller, in lieu of delivering the above documents, may deliver to the
Trustee a certification of a Servicing Officer to such effect and shall deposit
all amounts paid in respect of such Mortgage Loans in the Certificate Account on
the Closing Date. The Seller shall deliver such original documents (including
any original documents as to which certified copies had previously been
delivered) to the Trustee promptly after they are received. The Master Servicer
shall cause, at its expense, the Security Instrument and intervening
assignments, if any, and the assignment of the Security Instrument to the
Trustee to be recorded not later than 180 days after the Closing Date.

                  Section 2.02. ACCEPTANCE OF MORTGAGE LOANS BY TRUSTEE. (a) The
Trustee acknowledges receipt of, subject to its further review and the
exceptions it notes pursuant to the procedures described below, the documents
(or certified copies thereof) delivered to it pursuant to Section 2.01 and
declares that it holds and will continue to hold those documents and any
amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it as Trustee in trust for the use and benefit of all
present and future Holders of the Certificates. No later than 45 days after the
Closing Date (or, with respect to any Substitute Mortgage Loan, within 5 days
after the receipt by the Trustee thereof), the Trustee agrees, for the benefit
of the Certificateholders, to review each Mortgage File delivered to it and to
execute and deliver, or cause to be executed and delivered, to the Seller and
the Master Servicer an Initial Certification substantially in the form annexed
hereto as Exhibit G. In conducting such review, the Trustee will ascertain
whether all required documents have been executed and received and whether those
documents relate, determined on the basis of the Mortgagor name, original
principal balance and loan number, to the Mortgage Loans it has received, as
identified in Exhibit B to this Agreement, as supplemented (PROVIDED, HOWEVER,
that with respect to those documents described in subclauses (b)(iv), (b)(v) and
(b)(vi) of Section 2.01, the Trustee's obligations shall extend only to
documents actually delivered pursuant to such subsections). In performing any
such review, the Trustee may conclusively rely on the purported due execution
and genuineness of any such document and on the purported genuineness of any
signature thereon. If the Trustee finds any document constituting part of the
Mortgage File not to have been executed or received, or to be unrelated to the
Mortgage Loans identified in Exhibit B or to appear to be defective on its face,
the Trustee shall promptly notify BSMCC. BSMCC shall correct or cure any such
defect within 60 days from the date of notice from the Trustee of the defect and
if BSMCC fails to correct or cure the defect within such period, and such defect
materially and adversely affects the interests of the Certificateholders in the
related Mortgage Loan, BSMCC, will, subject to Section 2.05, within 90 days from
the Trustee's


                                      II-2

<PAGE>



notification purchase such Mortgage Loan at the Repurchase Price; PROVIDED,
HOWEVER, that if such defect relates solely to the inability of BSMCC to deliver
the original Security Instrument or intervening assignments thereof, or a
certified copy because the originals of such documents, or a certified copy have
not been returned by the applicable jurisdiction, BSMCC shall not be required to
purchase such Mortgage Loan if BSMCC delivers such original documents or
certified copy promptly upon receipt, but in no event later than 360 days after
the Closing Date.

                  (b) No later than 180 days after the Closing Date, the Trustee
will review, for the benefit of the Certificateholders, the Mortgage Files
delivered to it and will execute and deliver or cause to be executed and
delivered to the Seller and the Master Servicer, a Final Certification
substantially in the form annexed hereto as Exhibit H. In conducting such
review, the Trustee will ascertain whether an original of each document required
to be recorded has been returned from the recording office with evidence of
recording thereon or a certified copy has been obtained from the recording
office. If the Trustee finds any document constituting part of the Mortgage File
has not been received, or to be unrelated, determined on the basis of the
Mortgagor name, original principal balance and loan number, to the Mortgage
Loans identified in Exhibit B or to appear defective on its face, the Trustee
shall promptly notify BSMCC. BSMCC shall correct or cure any such defect or
shall deliver to the Trustee an Opinion of Counsel to the effect that such
defect does not materially or adversely affect the interests of
Certificateholders in such Mortgage Loan within 60 days from the date of notice
from the Trustee of the defect and if BSMCC is unable to cure such defect within
such period, and if such defect materially and adversely affects the interests
of the Certificateholders in the related Mortgage Loan, BSMCC shall, subject to
Section 2.05, within 90 days from the Trustee's notification purchase such
Mortgage Loan at the Repurchase Price; PROVIDED, HOWEVER, that if such defect
relates solely to the inability of BSMCC to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy, because the
originals of such documents, or a certified copy, have not been returned by the
applicable jurisdiction, BSMCC shall not be required to purchase such Mortgage
Loan, if BSMCC delivers such original documents or certified copy promptly upon
receipt, but in no event later than 360 days after the Closing Date.

                  (c) In the event that a Mortgage Loan is purchased by BSMCC in
accordance with Subsections 2.02(a) or (b) above or Section 3.19, BSMCC shall
cause the Repurchase Price to be deposited in the appropriate subaccount of the
Certificate Account and shall provide written notification of such deposit
(which notification shall detail the components of the Repurchase Price), signed
by a Servicing Officer, to the Trustee. Upon deposit of the Repurchase Price in
the appropriate subaccount of the Certificate Account, the Trustee shall release
to BSMCC the related Mortgage File and shall execute and deliver all instruments
of transfer or assignment, without recourse, furnished to it by BSMCC as are
necessary to vest in BSMCC title to and rights under the Mortgage Loan. Such
purchase shall be deemed to have occurred on the date on which certification of
the deposit of the Repurchase Price in the Certificate Account was received by
the Trustee. The Trustee shall amend the Mortgage Loan Schedule to reflect such
repurchase and shall promptly notify the Master Servicer and the Rating Agencies
of such amendment. The obligation of BSMCC to repurchase any Mortgage Loan as to
which such a defect in a constituent document exists shall be the sole remedy
respecting such defect available to the Certificateholders or to the Trustee on
their behalf.

                  Section 2.03. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
MASTER Servicer. (a) EMC hereby represents and warrants to the Trustee as of the
Closing Date that:

                           (i) It is a corporation duly organized, validly
                  existing and in good standing under the laws of the state of
                  its incorporation and is in good standing as a foreign
                  corporation in each jurisdiction where such qualification is
                  necessary and throughout the term of this Agreement will
                  remain a corporation duly organized, validly existing and in
                  good standing under the laws of the state of its incorporation
                  or any state of reincorporation and in good standing as a
                  foreign corporation in each jurisdiction where such
                  qualification is necessary (except, in the case of foreign
                  corporation qualification both on the date hereof and in the
                  future, where the failure so to qualify would not reasonably
                  be expected to have a material adverse effect on the Master
                  Servicer's ability to enter into this Agreement or to perform
                  its obligations hereunder), and has the corporate power and
                  authority to perform its obligations under this Agreement;

                           (ii) The execution and delivery of this Agreement
                  have been duly authorized by all requisite corporate action;

                           (iii) This Agreement, assuming due authorization,
                  execution, and delivery by the other parties hereto, will
                  constitute its legal, valid and binding obligation,
                  enforceable in accordance with its terms, except only as such
                  enforcement may be limited by applicable Debtor Relief Laws
                  and that certain equitable remedies may not be available
                  regardless of whether enforcement is sought in equity or at
                  law;

                           (iv) Its execution and delivery of this Agreement and
                  its performance and compliance with the terms of this
                  Agreement will not (A) violate its certificate of
                  incorporation or bylaws (B) to its knowledge, violate any law
                  or regulation, or any administrative or judicial decree or
                  order to which it is subject or (C) constitute a default (or
                  an event which, with notice or lapse of time, or both, would
                  constitute a default) under, or result in the breach of, any
                  material contract, agreement or other instrument to which it
                  is a party or which may be applicable to it or any of its
                  assets;

                           (v) To its best knowledge, after reasonable
                  investigation, it is not in default with respect to any order
                  or decree of any court or any order, regulation or demand of
                  any federal, state, municipal or governmental agency, which
                  default would reasonably be expected to have consequences that
                  would materially and adversely affect its financial condition
                  or operations or its performance hereunder;

                           (vi) It does not believe, nor does it have any reason
                  or cause to believe, that it cannot perform each and every
                  covenant contained in this Agreement to be performed by it;

                           (vii) The consummation of the transactions
                  contemplated by this Agreement are in the ordinary course of
                  its business; and

                           (viii) No litigation is pending or, to its best
                  knowledge, threatened against it, which could be reasonably
                  expected to materially and adversely affect its entering into
                  this Agreement or performing its obligations under this
                  Agreement or which would have a material adverse effect on its
                  financial condition.

                  Section 2.04. ASSIGNMENT OF INTEREST IN THE MORTGAGE LOAN
PURCHASE Agreement. (a) The Seller hereby assigns to the Trustee, on behalf of
the Certificateholders, all of its right, title and interest in the Mortgage
Loan Purchase Agreement (but none of its obligations) insofar as such contract
relates to the representations and warranties set forth in Exhibit C hereto
regarding the Mortgage Loans (including the substitution and repurchase
obligations of BSMCC; provided that the obligations of BSMCC to substitute or
repurchase a Mortgage Loan shall be the Trustee's and the Certificateholder's
sole remedy for any breach thereof. At the request of the Trustee, the Seller
shall take such actions as may be necessary to enforce the above right, title
and interest on behalf of the Trustee and the Certificateholders or shall
execute such further documents as the Trustee may reasonably require in order to
enable the Trustee to carry out such enforcement.

                  (b) If the Seller, BSMCC, the Master Servicer or the Trustee
discovers a breach of any of the representations and warranties set forth in
Exhibit C or Section 7 of the Mortgage Loan Purchase Agreement, and such breach
existed on the date the representation and warranty was made, which breach
materially and adversely affects the value of the interests of
Certificateholders or the Trustee in the related Mortgage Loan, the party
discovering the breach shall give prompt written notice of the breach to the
other parties. BSMCC within 60 days of its discovery or receipt of notice that
such breach has occurred (whichever occurs earlier), shall cure the breach in
all material respects or, subject to Section 2.05, shall purchase the Mortgage
Loan or any property acquired with respect thereto from the Trustee; PROVIDED,
HOWEVER, that if there is a breach of any representation set forth in Exhibit C
and the Mortgage Loan or the related property acquired with respect thereto has
been sold, then BSMCC shall pay, in lieu of the Repurchase Price, any excess of
the Repurchase Price over the Net Liquidation Proceeds received upon such sale.
(If the Net Liquidation Proceeds exceed the Repurchase Price, any excess shall
be paid to BSMCC to the extent not required by law to be paid to the borrower.)
Any such purchase by BSMCC shall be made by depositing an amount equal to the
Repurchase Price in the appropriate subaccount of the Certificate Account and
the Trustee, upon receipt of the Repurchase Price and of written notification of
such deposit by a Servicing Officer (which notification shall detail the
components of such Repurchase Price), shall release to BSMCC the related
Mortgage File and shall execute and deliver all instruments of transfer or
assignment furnished to it by BSMCC, without recourse, as are necessary to vest
in BSMCC title to and rights under the Mortgage Loan or any property acquired
with respect thereto. Such purchase shall be deemed to have occurred on the date
on which certification of the deposit of the Repurchase Price in the appropriate
subaccount of the Certificate Account was received by the Trustee. The Trustee
shall amend the Mortgage Loan Schedule to reflect such repurchase and shall
promptly notify the Master Servicer and the Rating Agencies of such amendment.
Enforcement of the obligation of BSMCC to purchase (or substitute a Substitute
Mortgage Loan for) any Mortgage Loan or any property acquired with respect
thereto (or pay the Repurchase Price as set forth in the above proviso) as to
which a breach has occurred and is continuing shall constitute the sole remedy
respecting such breach available to the Certificateholders or the Trustee on
their behalf.

                  Section 2.05. SUBSTITUTION OF MORTGAGE LOANS. Notwithstanding
anything to the contrary in this Agreement, in lieu of purchasing a Mortgage
Loan pursuant to Sections 2.02 or 2.04, BSMCC may, no later than the date by
which such purchase by BSMCC would otherwise be required, tender to the Trustee
a Substitute Mortgage Loan accompanied by an Officer's Certificate of BSMCC that
such Substitute Mortgage Loan conforms to the requirements set forth in the
definition of "Substitute Mortgage Loan"; PROVIDED, HOWEVER, that substitution
pursuant to this Section 2.05 in lieu of purchase shall not be permitted after
the termination of the two-year period beginning on the Startup Day. The Trustee
shall examine the Mortgage File for any Substitute Mortgage Loan in the manner
set forth in Section 2.02(a) and shall notify the Master Servicer in writing,
within five Business Days after receipt, whether or not the documents relating
to the Substitute Mortgage Loan satisfy the requirements of the third sentence
of Subsection 2.02(a). Within two Business Days after such notification, BSMCC
shall deposit in the appropriate subaccount of the Certificate Account the
amount, if any, by which the Outstanding Principal Balance as of the next
preceding Due Date of the Mortgage Loan for which substitution is being made,
after giving effect to Scheduled Principal due on such date, exceeds the
Outstanding Principal Balance as of such date of the Substitute Mortgage Loan,
after giving effect to Scheduled Principal due on such date, which amount shall
be treated for the purposes of this Agreement as if it were the payment by BSMCC
of the Repurchase Price for the purchase of a Mortgage Loan by BSMCC. After such
notification to BSMCC, and, if any such excess exists, upon receipt of such
deposit and of written notification thereof signed by a Servicing Officer, the
Trustee shall accept such Substitute Mortgage Loan, which shall thereafter be
deemed to be a Group I Mortgage Loan, Group II Mortgage Loan, Group III Mortgage
Loan, Group IV Mortgage Loan or Group V Mortgage Loan, as applicable, hereunder.
In the event of such a substitution, accrued interest on the Substitute Mortgage
Loan for the month in which the substitution occurs and any Principal
Prepayments made thereon during such month shall be the property of the Trust
Fund and accrued interest for such month on the Mortgage Loan for which the
substitution is made and any Principal Prepayments made thereon during such
month shall be the property of BSMCC. The Scheduled Principal on a Substitute
Mortgage Loan due on the Due Date in the month of substitution shall be the
property of BSMCC and the Scheduled Principal on the Mortgage Loan for which the
substitution is made due on such Due Date shall be the property of the Trust
Fund. Upon acceptance of the Substitute Mortgage Loan, the Trustee shall release
to BSMCC the related Mortgage File related to any Mortgage Loan released
pursuant to this Section 2.05 and shall execute and deliver all instruments of
transfer or assignment, without recourse, in form as provided to it as are
necessary to vest in BSMCC title to and rights under any Mortgage Loan released
pursuant to this Section 2.05. BSMCC shall deliver the documents related to the
Substitute Mortgage Loan in accordance with the provisions of Subsections
2.01(b) and 2.02(b), with the date of acceptance of the Substitute Mortgage Loan
deemed to be the Closing Date for purposes of the time periods set forth in
those Subsections. The representations and warranties set forth in Exhibit C
shall be deemed to have been made by BSMCC with respect to each Substitute
Mortgage Loan as of the date of acceptance of such Mortgage Loan by the Trustee.
The Trustee shall amend the Mortgage Loan Schedule to reflect such substitution
and shall provide a copy of such amended Mortgage Loan Schedule to the Master
Servicer and the Rating Agencies.

                  Section 2.06. REPRESENTATIONS AND WARRANTIES OF THE TRUSTEE.
The Trustee hereby represents and warrants to the Seller and the Master
Servicer, as of the Closing Date (and in the case of paragraphs (v) and (vi)
below throughout the term of the Agreement), that:


                                      II-6

<PAGE>




                           (i) The Trustee is a trust company duly organized,
                  validly existing and in good standing under the laws of the
                  Commonwealth of Massachusetts with a principal place of
                  business in Boston, Massachusetts;

                           (ii) Subject to the right of the Trustee to appoint a
                  co-trustee or separate trustee under Section 9.11 hereof in
                  order to meet the legal requirements of a particular
                  jurisdiction, the Trustee has full power, authority and legal
                  right to execute and deliver this Agreement and to perform its
                  obligations under this Agreement and has taken all necessary
                  action to authorize the execution, delivery and performance by
                  it of this Agreement and the Certificates;

                           (iii) To the best of the Trustee's knowledge, after
                  reasonable investigation, the execution and delivery by the
                  Trustee of this Agreement and the Certificates and the
                  performance by the Trustee of its obligations under this
                  Agreement and the Certificates will not violate any provision
                  of the Trustee's Articles of Incorporation or By-Laws or any
                  law or regulation governing the Trustee or any order, writ,
                  judgment or decree of any court, arbitrator or governmental
                  authority or agency applicable to the Trustee or any of its
                  assets. To the best of the Trustee's knowledge, after
                  reasonable investigation, such execution, delivery and
                  performance will not require the authorization, consent or
                  approval of, the giving of notice to, the filing or
                  registration with, or the taking of any other action with
                  respect to, any governmental authority or agency regulating
                  the activities of a Massachusetts trust company. To the best
                  of the Trustee's knowledge, after reasonable investigation,
                  such execution, delivery and performance will not conflict
                  with, or result in a breach or violation of, any material
                  indenture, mortgage, deed of trust, lease or other agreement
                  or instrument to which the Trustee is a party or by which it
                  or its properties is bound;

                           (iv) This Agreement has been duly executed and
                  delivered by the Trustee. This Agreement, when executed and
                  delivered, will constitute the valid, legal and binding
                  obligation of the Trustee, enforceable against the Trustee in
                  accordance with its terms, except as the enforcement thereof
                  may be limited by applicable Debtor Relief Laws and that
                  certain equitable remedies may not be available regardless of
                  whether enforcement is sought in equity or at law; and

                           (v) All funds received by the Trustee and required to
                  be deposited in the Certificate Account and the Custody
                  Account pursuant to this Agreement will be
                  promptly so deposited.

                  Section 2.07. ISSUANCE OF CERTIFICATES. The Trustee
acknowledges the assignment to it of the Mortgage Loans and the other assets
comprising the Trust Fund and, concurrently therewith, has signed, and
countersigned and delivered to the Seller, in exchange therefor, Certificates in
such authorized denominations representing such Fractional Undivided Interests
as the Seller has requested. The Trustee agrees that it will hold the Mortgage
Loans and such other assets segregated on the books of the Trustee in trust for
the benefit of the Certificateholders.

                  Section 2.08. REPRESENTATIONS AND WARRANTIES CONCERNING THE
SELLER. The Seller hereby represents and warrants to the Trustee and the Master
Servicer as follows:

                           (i) the Seller (a) is a corporation duly organized,
                  validly existing and in good standing under the laws of the
                  State of Delaware and (b) is qualified and in good standing as
                  a foreign corporation to do business in each jurisdiction
                  where such qualification is necessary, except where the
                  failure so to qualify would not reasonably be expected to have
                  a material adverse effect on the Seller's business as
                  presently conducted or on the Purchaser's ability to enter
                  into this Agreement and to consummate the transactions
                  contemplated hereby;

                           (ii) the Seller has full corporate power to own its
                  property, to carry on its business as presently conducted and
                  to enter into and perform its obligations under this
                  Agreement;

                           (iii) the execution and delivery by the Seller of
                  this Agreement have been duly authorized by all necessary
                  corporate action on the part of the Seller; and neither the
                  execution and delivery of this Agreement, nor the consummation
                  of the transactions herein contemplated, nor compliance with
                  the provisions hereof, will conflict with or result in a
                  breach of, or constitute a default under, any of the
                  provisions of any law, governmental rule, regulation,
                  judgment, decree or order binding on the Seller or its
                  properties or the articles of incorporation or by-laws of the
                  Seller, except those conflicts, breaches or defaults which
                  would not reasonably be expected to have a material adverse
                  effect on the Seller's ability to enter into this Agreement
                  and to consummate the transactions contemplated hereby;

                           (iv) the execution, delivery and performance by the
                  Seller of this Agreement and the consummation of the
                  transactions contemplated hereby do not require the consent or
                  approval of, the giving of notice to, the registration with,
                  or the taking of any other action in respect of, any state,
                  federal or other governmental authority or agency, except
                  those consents, approvals, notices, registrations or other
                  actions as have already been obtained, given or made;

                           (v) this Agreement has been duly executed and
                  delivered by the Seller and, assuming due authorization,
                  execution and delivery by the other parties hereto,
                  constitutes a valid and binding obligation of the Seller
                  enforceable against it in accordance with its terms (subject
                  to applicable bankruptcy and insolvency laws and other similar
                  laws affecting the enforcement of the rights of creditors
                  generally); and

                           (vi) there are no actions, suits or proceedings
                  pending or, to the knowledge of the Seller, threatened against
                  the Seller, before or by any court, administrative agency,
                  arbitrator or governmental body (i) with respect to any of the
                  transactions contemplated by this Agreement or (ii) with
                  respect to any other matter which in the judgment of the
                  Seller will be determined adversely to the Seller and will if
                  determined adversely to the Seller materially and adversely
                  affect the Seller's ability to enter into this Agreement or
                  perform its obligations under this Agreement; and the

                  Seller is not in default with respect to any order of any
                  court, administrative agency, arbitrator or governmental body
                  so as to materially and adversely affect the transactions
                  contemplated by this Agreement.

                                   ARTICLE III

                 Administration and Servicing of Mortgage Loans

                  Section 3.01. MASTER SERVICER TO ASSURE SERVICING. (a) The
Master Servicer shall supervise, or take such actions as are necessary to
ensure, the servicing and administration of the Mortgage Loans and any REO
Property in accordance with this Agreement and its normal servicing practices
(including making any Servicing Advances), which generally conform to the
standards of an institution prudently servicing mortgage loans for its own
account and shall have full authority to do anything it reasonably deems
appropriate or desirable in connection with such servicing and administration.
The Master Servicer may perform its responsibilities relating to servicing
through other agents or independent contractors, but shall not thereby be
released from any of its responsibilities as hereinafter set forth. The
authority of the Master Servicer, in its capacity as master servicer, shall
include, without limitation, the power to (i) consult with and advise any Sub-
Servicer regarding administration of a related Mortgage Loan, (ii) approve any
recommendation by a Sub-Servicer to foreclose on a related Mortgage Loan, (iii)
supervise the filing and collection of insurance claims and take or cause to be
taken such actions on behalf of the insured person thereunder as shall be
reasonably necessary to prevent the denial of coverage thereunder, and (iv)
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing a related Mortgage Loan, including the employment of
attorneys, the institution of legal proceedings, the collection of deficiency
judgments, the acceptance of compromise proposals, the filing of claims under
any Primary Mortgage Insurance Policy and any other matter pertaining to a
delinquent Mortgage Loan. The authority of the Master Servicer shall include, in
addition, the power on behalf of the Certificateholders, the Trustee or any of
them to (i) execute and deliver customary consents or waivers and other
instruments and documents, (ii) consent to transfers of any related Mortgaged
Property and assumptions of the related Mortgage Notes and Security Instruments
(in the manner provided in this Agreement) and (iii) collect any Insurance
Proceeds and Liquidation Proceeds. Without limiting the generality of the
foregoing, the Master Servicer may, and is hereby authorized, and empowered by
the Trustee to, execute and deliver, on behalf of itself, the
Certificateholders, the Trustee, or any of them, any instruments of
satisfaction, cancellation, partial or full release, discharge and all other
comparable instruments, with respect to the related Mortgage Loans, the
Insurance Policies and the accounts related thereto, and the Mortgaged
Properties. The Master Servicer may exercise this power in its own name or in
the name of a Sub-Servicer.

                  (b) Notwithstanding the provisions of Subsection 3.01(a), the
Master Servicer shall not take any action inconsistent with the interest of the
Trustee or the Certificateholders in the Mortgage Loans or with the rights and
interests of the Trustee or the Certificateholders under this
Agreement.

                  (c) The Trustee shall furnish the Master Servicer with any
powers of attorney and other documents in form as provided to it necessary or
appropriate to enable the Master Servicer to
service and administer the related Mortgage Loans and REO Property.

                  Section 3.02. SUB-SERVICING AGREEMENTS BETWEEN MASTER SERVICER
AND SUB- SERVICERS. (a) The Master Servicer may enter into Sub-Servicing
Agreements with Sub-Servicers for the servicing and administration of the
Mortgage Loans and for the performance of any and all


                                      III-1

<PAGE>



other activities of the Master Service hereunder. Each Sub-Servicer shall be
either (i) an institution the accounts of which are insured by the FDIC or (ii)
another entity that engages in the business of originating or servicing mortgage
loans, and in either case shall be authorized to transact business in the state
or states in which the related Mortgaged Properties it is to service are
situated, if and to the extent required by applicable law to enable the
Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing
Agreement, and in either case shall be a FHLMC or FNMA approved mortgage
servicer. Any Sub-Servicing Agreement entered into by the Master Servicer shall
include the provision that such Agreement may be immediately terminated (x) with
cause and without any termination fee by any Master Servicer hereunder other
than EMC or (y) without cause in which case the Master Servicer shall be
responsible for any termination fee or penalty resulting therefrom. In addition,
any Sub-Servicing Agreement shall provide for servicing of the Mortgage Loans
consistent with the terms of this Agreement. With the consent of the Trustee,
which consent shall not be unreasonably withheld, the Master Servicer and the
Sub-Servicers may enter into Sub-Servicing Agreements and make amendments to the
Sub-Servicing Agreements or enter into different forms of Sub-Servicing
Agreements; provided, however, that any such amendments or different forms shall
be consistent with and not violate the provisions of this Agreement, and that no
such amendment or different form shall be made or entered into which could be
reasonably expected to be materially adverse to the interests of the
Certificateholders, without the consent of the Holders of Certificates entitled
to at least 51% of the Fractional Undivided Interests of all the Certificates in
the aggregate.

                  (b) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall
enforce the obligations of each Sub-Servicer under the related Sub-Servicing
Agreement. Such enforcement, including, without limitation, the legal
prosecution of claims, termination of Sub-Servicing Agreements and the pursuit
of other appropriate remedies, shall be in such form and carried out to such an
extent and at such time as the Master Servicer, in its good faith business
judgment, would require were it the owner of the related Mortgage Loans. The
Master Servicer shall pay the costs of such enforcement at its own expense, but
shall be reimbursed therefor only (i) from a general recovery resulting from
such enforcement only to the extent, if any, that such recovery exceeds all
amounts due in respect of the related Mortgage Loans or (ii) from a specific
recovery of costs, expenses or attorneys' fees against the party against whom
such enforcement is directed.

                  Section 3.03. SUCCESSOR SUB-SERVICERS. The Master Servicer
shall be entitled to terminate any Sub-Servicing Agreement that may exist in
accordance with the terms and conditions of such Sub-Servicing Agreement and
without any limitation by virtue of this Agreement; PROVIDED, HOWEVER, that upon
termination, the Master Servicer shall either act as servicer of the related
Mortgage Loan or enter into an appropriate contract with a successor
Sub-Servicer pursuant to which such successor Sub-Servicer will be bound by all
relevant terms of the related Sub-Servicing Agreement pertaining to the
servicing of such Mortgage Loan.

                  Section 3.04. LIABILITY OF THE MASTER SERVICER. (a)
Notwithstanding any Sub- Servicing Agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Master Servicer and
a Sub-Servicer or reference to actions taken through a Sub-Servicer or
otherwise, the Master Servicer shall under all circumstances remain obligated
and primarily liable to the Trustee and the Certificateholders for the servicing
and administering of the Mortgage Loans and any REO Property in accordance with
this Agreement. The obligations and


                                      III-2

<PAGE>



liability of the Master Servicer shall not be diminished by virtue of
Sub-Servicing Agreements or by virtue of indemnification of the Master Servicer
by any Sub-Servicer, or any other Person. The obligations and liability of the
Master Servicer shall remain of the same nature and under the same terms and
conditions as if the Master Servicer alone were servicing and administering the
related Mortgage Loans. The Master Servicer shall, however, be entitled to enter
into indemnification agreements with any Sub-Servicer or other Person and
nothing in this Agreement shall be deemed to limit or modify such
indemnification. For the purposes of this Agreement, the Master Servicer shall
be deemed to have received any payment on a Mortgage Loan on the date the
Sub-Servicer received such payment; PROVIDED, HOWEVER, that this sentence shall
not apply to the Trustee acting as the Master Servicer; PROVIDED, FURTHER,
HOWEVER, that the foregoing provision shall not affect the obligation of the
Master Servicer if it is also the Trustee to advance amounts which are not
Nonrecoverable Advances.

                  (b) Any Sub-Servicing Agreement that may be entered into and
any transactions or services relating to the Mortgage Loans involving a
Sub-Servicer in its capacity as such and not as an originator shall be deemed to
be between the Sub-Servicer and the Master Servicer alone, and the Trustee and
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Sub-Servicer
except as set forth in Section 3.05.

                  Section 3.05. ASSUMPTION OR TERMINATION OF SUB-SERVICING
AGREEMENTS BY TRUSTEE. (a) If the Trustee or its designee shall assume the
master servicing obligations of the Master Servicer in accordance with Section
8.02, the Trustee, to the extent necessary to permit the Trustee to carry out
the provisions of Section 8.02 with respect to the Mortgage Loans, shall succeed
to all of the rights and obligations of the Master Servicer under each of the
Sub-Servicing Agreements. In such event, the Trustee or its designee as the
successor master servicer shall be deemed to have assumed all of the Master
Servicer's rights and obligations therein and to have replaced the Master
Servicer as a party to such Sub-Servicing Agreements to the same extent as if
such Sub-Servicing Agreements had been assigned to the Trustee or its designee
as a successor master servicer, except that the Trustee or its designee as a
successor master servicer shall not be deemed to have assumed any obligations or
liabilities of the Master Servicer arising prior to such assumption and the
Master Servicer shall not thereby be relieved of any liability or obligations
under such Sub-Servicing Agreements.

                  (b) In the event that the Trustee or its designee as successor
master servicer for the Trustee assumes the servicing obligations of the Master
Servicer under Section 8.02, upon the reasonable request of the Trustee or such
designee as successor master servicer, the Master Servicer shall at its own
expense deliver to the Trustee, or at its written request to such designee,
photocopies of all documents and records, electronic or otherwise, relating to
the Sub-Servicing Agreements and the related Mortgage Loans or REO Property then
being serviced and an accounting of amounts collected and held by it, if any,
and will otherwise cooperate and use its reasonable best efforts to effect the
orderly and efficient transfer of the Sub-Servicing Agreements, or
responsibilities hereunder to the Trustee, or at its written request to such
designee as successor master servicer.

                  Section 3.06. COLLECTION OF MORTGAGE LOAN PAYMENTS. (a) The
Master Servicer will coordinate and monitor remittances by Sub-Servicers to the
Trustee with respect to the Mortgage Loans in accordance with this Agreement.

                  (b) The Master Servicer shall make its reasonable best efforts
to collect or cause to be collected all payments required under the terms and
provisions of the Mortgage Loans and shall follow, and use its best efforts to
cause Sub-Servicers to follow, collection procedures comparable to the
collection procedures of prudent mortgage lenders servicing mortgage loans for
their own account to the extent such procedures shall be consistent with this
Agreement. Consistent with the foregoing, the Master Servicer may in its
discretion (i) waive or permit to be waived any late payment charge, prepayment
charge, assumption fee, or any penalty interest in connection with the
prepayment of a Mortgage Loan and (ii) suspend or reduce or permit to be
suspended or reduced regular monthly payments for a period of up to six months,
or arrange or permit an arrangement with a Mortgagor for a scheduled liquidation
of delinquencies. In the event the Master Servicer shall consent to the
deferment of the due dates for payments due on a Mortgage Note, the Master
Servicer shall nonetheless make a Monthly Advance or shall cause the related
Sub-Servicer to make an advance to the same extent as if such installment were
due, owing and delinquent and had not been deferred through liquidation of the
Mortgaged Property; PROVIDED, HOWEVER, that the obligation of the Master
Servicer to make a Monthly Advance shall apply only to the extent that the
Master Servicer believes, in good faith, that such advances are not
Nonrecoverable Advances.

                  (c) Notwithstanding anything in this Agreement to the
contrary, the Master Servicer may not make any future advances with respect to a
Mortgage Loan and the Master Servicer shall not (unless the Mortgagor is in
default with respect to the Mortgage Loan or such default is, in the judgment of
the Master Servicer, reasonably foreseeable) permit (i) any modification with
respect to any Mortgage Loan that would change the Mortgage Interest Rate,
reduce or increase the principal balance (except for reductions resulting from
actual payments of principal) or change the final maturity date on such Mortgage
Loan or (ii) any modification, waiver or amendment of any term of any Mortgage
Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan
under Section 1001 of the Code (or final, temporary or proposed Treasury
regulations promulgated thereunder) and (B) cause the Trust Fund to fail to
qualify as a REMIC under the Code or the imposition of any tax on "prohibited
transactions" or "contributions after the startup date" under the REMIC
Provisions. Any extension of the final maturity date of any Mortgage Loan shall
be calculated such that the Mortgage Loan will be paid in full on the reset
final maturity date if the related Mortgagor continues to make its then-current
Monthly Scheduled Payments on a timely basis.

                  (d) Within five Business Days after the Master Servicer has
determined that all amounts which it expects to recover from or on account of a
Mortgage Loan have been recovered and that no further Liquidation Proceeds will
be received in connection therewith, the Master Servicer shall provide to the
Trustee a certificate of a Servicing Officer that such Mortgage Loan became a
Liquidated Mortgage Loan as of the date of such determination.

                  Section 3.07. COLLECTION OF TAXES, ASSESSMENTS AND SIMILAR
ITEMS; SERVICING ACCOUNTS. (a) The Master Servicer shall establish and maintain
or cause the Sub-Servicers to establish and maintain, in addition to the
Protected Accounts, one or more Servicing Accounts. The Master Servicer or a
Sub-Servicer will deposit and retain therein all otherwise unapplied collections


                                      III-4

<PAGE>



from the Mortgagors, including amounts collected for the payment of taxes,
assessments, insurance premiums, or comparable items as agent of the Mortgagors.

                  (b) The deposits in the Servicing Accounts shall be held in a
Designated Depository Institution in an account designated as a "Mortgage Loan
Servicing Account," held in trust by the Master Servicer or a Sub-Servicer as
Trustee of Taxes and Insurance Custodial Account for borrowers and for EMC (and
its successors and assigns) acting on its own behalf and for EMC as agent for
holders of various pass-through securities and other interests in mortgage loans
sold by it; and agent for various mortgagors, as their interests may appear or
under such other designation as may be permitted by a Sub-Servicing Agreement.
The amount at any time credited to a Servicing Account must be fully insured by
the FDIC, or, to the extent that such deposits exceed the limits of such
insurance, such excess must be (i) transferred to another fully insured account
in another Designated Depository Institution or (ii) if permitted by applicable
law, invested in Permitted Investments held in trust by the Master Servicer or a
Sub-Servicer as described above and maturing, or be subject to redemption or
withdrawal, no later than the date on which such funds are required to be
withdrawn, and in no event later than 45 days after the date of investment. The
Master Servicer may, or may permit a Sub-Servicer to, establish Servicing
Accounts not conforming to the foregoing requirements to the extent that such
Servicing Accounts are Rating Agency Eligible Accounts. Withdrawals of amounts
from the Servicing Accounts may be made only to effect timely payment of taxes,
assessments, insurance premiums, or comparable items, to transfer previously
unapplied collections to a Protected Account, to reimburse the Master Servicer
or a Sub-Servicer for any advances made with respect to such items, to refund to
any Mortgagors any sums as may be determined to be overages, to pay interest, if
required, to Mortgagors on balances in the Servicing Accounts or to clear and
terminate the Servicing Accounts at or any time after the termination of this
Agreement in accordance with Section 10.01.

                  Section 3.08. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION
REGARDING THE MORTGAGE LOANS. The Master Servicer shall provide, and shall cause
any Sub-Servicer to provide, to the Trustee and the Seller access to the
documentation regarding the related Mortgage Loans and REO Property and to the
Certificateholders, the FDIC, and the supervisory agents and examiners of the
FDIC (to which the Trustee shall also provide) access to the documentation
regarding the related Mortgage Loans required by applicable regulations, such
access being afforded without charge but only upon reasonable prior written
request and during normal business hours at the offices of the Master Servicer,
the Sub-Servicers or the Trustee that are designated by these entities;
PROVIDED, HOWEVER, that, unless otherwise required by law, the Trustee, the
Master Servicer or the Sub-Servicer shall not be required to provide access to
such documentation if the provision thereof would violate the legal right to
privacy of any Mortgagor PROVIDED, FURTHER, HOWEVER, that the Trustee and the
Seller shall coordinate their requests for such access so as not to impose an
unreasonable burden on, or cause an interruption of, the business of the Master
Servicer or any Sub-Servicer. The Master Servicer, the Sub-Servicers and the
Trustee shall allow representatives of the above entities to photocopy any of
the documentation and shall provide equipment for that purpose at a charge that
covers their own actual out-of-pocket costs.

                  Section 3.09. MAINTENANCE OF PRIMARY MORTGAGE INSURANCE
POLICIES; COLLECTION THEREUNDER. The Master Servicer shall, or shall cause the
related Sub-Servicer to, exercise its best reasonable efforts to maintain and
keep in full force and effect each Primary Mortgage Insurance


                                      III-5

<PAGE>



Policy by a Qualified Insurer, or other insurer satisfactory to the Rating
Agencies, with respect to each conventional Mortgage Loan as to which as of the
Cut-off Date such a Primary Mortgage Insurance Policy was in effect (or, in the
case of a Substitute Mortgage Loan, the date of substitution) and the original
principal amount of the related Mortgage Note exceeded 80% of the Original Value
in an amount at least equal to the excess of such original principal amount over
75% of such Original Value until the principal amount of any such Mortgage Loan
is reduced below 80% of the Original Value or, based upon a new appraisal, the
principal amount of such Mortgage Loan represents less than 80% of the new
appraised value. The Master Servicer shall, or shall cause the related Sub-
Servicer to, effect the timely payment of the premium on each Primary Mortgage
Insurance Policy. The Master Servicer and the related Sub-Servicer shall have
the power to substitute for any Primary Mortgage Insurance Policy another
substantially equivalent policy issued by another Qualified Insurer; PROVIDED
THAT such substitution is subject to the condition, to be evidenced by a writing
from each Rating Agency, that it would not cause the ratings on the Certificates
to be downgraded or withdrawn.

                  Section 3.10. MAINTENANCE OF HAZARD INSURANCE AND FIDELITY
COVERAGE. (a) The Master Servicer shall maintain and keep, or cause each
Sub-Servicer to maintain and keep, with respect to each Mortgage Loan and each
REO Property, in full force and effect hazard insurance (fire insurance with
extended coverage) equal to at least the lesser of the Outstanding Principal
Balance of the Mortgage Loan or the current replacement cost of the Mortgaged
Property, and containing a standard mortgagee clause; PROVIDED, HOWEVER, that
the amount of hazard insurance may not be less than the amount necessary to
prevent loss due to the application of any co-insurance provision of the related
policy. Unless applicable state law requires a higher deductible, the deductible
on such hazard insurance policy may be no more than $1000 or 1% of the
applicable amount of coverage, whichever is less. In the case of a condominium
unit or a unit in a planned unit development, the required hazard insurance
shall take the form of a multiperil policy covering the entire condominium
project or planned unit development, in an amount equal to at least 100% of the
insurable value based on replacement cost.

                  (b) Any amounts collected by the Master Servicer or a
Sub-Servicer under any such hazard insurance policy (other than amounts to be
applied to the restoration or repair of the Mortgaged Property or amounts
released to the Mortgagor in accordance with the Master Servicer's or a
Sub-Servicer's normal servicing procedures, the terms of the Mortgage Note, the
Security Instrument or applicable law) shall be deposited initially in a
Protected Account, for transmittal to the appropriate subaccount of the
Certificate Account or Custody Account, subject to withdrawal pursuant to
Section 4.03.

                  (c) Any cost incurred by a Master Servicer or a Sub-Servicer
in maintaining any such hazard insurance policy shall not be added to the amount
owing under the Mortgage Loan for the purpose of calculating monthly
distributions to Certificateholders, notwithstanding that the terms of the
Mortgage Loan so permit. Such costs shall be recoverable by the Master Servicer
or a Sub- Servicer out of related late payments by the Mortgagor or out of
Insurance Proceeds or Liquidation Proceeds or by the Master Servicer from the
Repurchase Price, to the extent permitted by Section 4.03.

                  (d) No earthquake or other additional insurance is to be
required of any Mortgagor or maintained on property acquired with respect to a
Security Instrument other than pursuant to such applicable laws and regulations
as shall at any time be in force and shall require such additional insurance.
Each year, in accordance with standards and procedures required by FHLMC, the
Master Servicer shall perform a review of the Mortgage Loans to determine which,
if any, of the Mortgaged Properties are located in a federally designated
special flood hazard area and for each Mortgaged Property found to be located in
a federally designated special flood hazard area, the Master Servicer shall use
its best reasonable efforts to cause with respect to the Mortgage Loans and each
REO Property, flood insurance (to the extent available and in accordance with
mortgage servicing industry practice) to be maintained. Such flood insurance
shall cover the Mortgaged Property, including all items taken into account in
arriving at the Appraised Value on which the Mortgage Loan was based, and shall
be in an amount equal to the lesser of (i) the Outstanding Principal Balance of
the related Mortgage Loan and (ii) the minimum amount required under the terms
of coverage to compensate for any damage or loss on a replacement cost basis,
but not more than the maximum amount of such insurance available for the related
Mortgaged Property under either the regular or emergency programs of the
National Flood Insurance Program (assuming that the area in which such Mortgaged
Property is located is participating in such program). Unless applicable state
law requires a higher deductible, the deductible on such flood insurance may not
exceed $1,000 or 1% of the applicable amount of coverage, whichever is less.

                  (e) If insurance has not been maintained complying with
Subsections 3.10(a) and (d) and there shall have been a loss which would have
been covered by such insurance had it been maintained, the Master Servicer shall
pay, or cause the related Sub-Servicer to pay, for any necessary repairs.

                  (f) The Master Servicer shall present, or cause the related
Sub-Servicer to present, if it is a permitted claimant, claims under the related
hazard insurance or flood insurance policy.

                  (g) The Master Servicer shall obtain and maintain at its own
expense and for the duration of this Agreement a blanket fidelity bond and shall
cause each Sub-Servicer to obtain and maintain an errors and omissions insurance
policy covering such Sub-Servicer's officers, employees and other persons acting
on its behalf in connection with its activities under this Agreement. The amount
of coverage shall be at least equal to the coverage maintained by the Master
Servicer acceptable to FNMA or FHLMC to service loans for it or otherwise in an
amount as is commercially available at a cost that is generally not regarded as
excessive by industry standards. The Master Servicer shall promptly notify the
Trustee of any material change in the terms of such bond or policy. The Master
Servicer shall provide annually to the Trustee a certificate of insurance that
such bond and policy are in effect. If any such bond or policy ceases to be in
effect, the Master Servicer shall, to the extent possible, give the Trustee ten
days' notice prior to any such cessation and shall use its best efforts to
obtain a comparable replacement bond or policy, as the case may be. Any amounts
relating to the Mortgage Loans collected under such bond or policy shall be
remitted to the appropriate subaccount of the Certificate Account to the extent
that such amounts have not previously been paid to such account.

                  Section 3.11. DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS. (a)
In any case in which the Master Servicer is notified by any Mortgagor or
Sub-Servicer that a Mortgaged Property


                                      III-7

<PAGE>



relating to a Mortgage Loan has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall enforce, or shall instruct such
Sub-Servicer to enforce, any due-on-sale clause contained in the related
Security Instrument to the extent permitted under the terms of the related
Mortgage Note and by applicable law unless the Master Servicer reasonably
believes such enforcement is likely to result in legal action by the Mortgagor.
The Master Servicer or the related Sub-Servicer may purchase a Mortgage Loan at
the Repurchase Price when the Master Servicer requires acceleration of the
Mortgage Loan, but only if the Master Servicer is satisfied, as evidenced by an
Officer's Certificate delivered to the Trustee, that either (i) such Mortgage
Loan is in default or default is reasonably foreseeable or (ii) if such Mortgage
Loan is not in default or default is not reasonably foreseeable, such repurchase
will have no adverse tax consequences for the Trust Fund or any
Certificateholder. If the Master Servicer reasonably believes that such
due-on-sale clause cannot be enforced under applicable law or if the Mortgage
Loan does not contain a due-on-sale clause, the Master Servicer is authorized,
and may authorize any Sub-Servicer, to consent to a conveyance subject to the
lien of the Mortgage, and to take or enter into an assumption agreement from or
with the Person to whom such property has been or is about to be conveyed,
pursuant to which such Person becomes liable under the related Mortgage Note and
unless prohibited by applicable state law, such Mortgagor remains liable
thereon, on condition, however, that the related Mortgage Loan shall continue to
be covered (if so covered before the Master Servicer or the related Sub-Servicer
enters into such agreement) by any Primary Mortgage Insurance Policy. The Master
Servicer shall notify the Trustee, whenever possible, before the completion of
such assumption agreement, and shall forward to the Trustee the original copy of
such assumption agreement, which copy shall be added by the Trustee to the
related Mortgage File and which shall, for all purposes, be considered a part of
such Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. In connection with any such assumption agreement,
the interest rate on the related Mortgage Loan shall not be changed and no other
material alterations in the Mortgage Loan shall be made unless such material
alteration would not cause the REMIC to fail to qualify as a REMIC for federal
income tax purposes, as evidenced by a REMIC Opinion. If the interest rate on an
assumed Mortgage Loan is increased due to both (i) permitted increases upon
assumption under the terms of such Mortgage Loan and (ii) all applicable
restrictions hereunder being satisfied, the Master Servicer shall, as part of
the report to the Trustee and the Seller pursuant to Section 6.06(b) hereof,
provide therefor on a revised Mortgage Loan Schedule. Any fee or additional
interest collected by the Master Servicer or Sub-Servicer for consenting to any
such conveyance or entering into any such assumption agreement may be retained
by the Master Servicer or the related Sub- Servicer as additional servicing
compensation.

                  (b) 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 conveyance by the
Mortgagor of the related Mortgaged Property or assumption of a Mortgage Loan
which the Master Servicer reasonably believes, based on prudent servicing
standards, it may be restricted by law from preventing, for any reason
whatsoever or if the exercise of such right would impair or threaten to impair
any recovery under any applicable Insurance Policy, or, in the Master Servicer's
judgment, be reasonably, likely to result in legal action by the Mortgagor or
would adversely affect the Certificateholders.

                  Section 3.12. REALIZATION UPON DEFAULTED MORTGAGE LOANS. (a)
The Master Servicer shall, or shall direct the related Sub-Servicer to,
foreclose upon or otherwise comparably convert the ownership of properties
securing any Mortgage Loans that come into and continue in default and as to
which no satisfactory arrangements can be made for collection of delinquent
payments pursuant to Section 3.06 except that the Master Servicer shall not, and
shall not direct the related Sub- Servicer, if any, to, foreclose upon or
otherwise comparably convert a Mortgaged Property if there is evidence of
environmental hazards or toxic waste thereon and the Master Servicer determines
it would be imprudent to do so or not in accordance with appropriate servicing
standards. The Master Servicer can conclusively rely on results of third party
inspections from parties it reasonably believes are qualified to conduct such
inspections. In connection with such foreclosure or other conversion, the Master
Servicer in conjunction with the related Sub-Servicer, if any, shall use its
best reasonable efforts to preserve REO Property and to realize upon defaulted
Mortgage Loans in such manner as to maximize the receipt of principal and
interest by the Certificateholders, taking into account, among other things, the
timing of foreclosure and the considerations set forth in Subsection 3.12(b).
The foregoing is subject to the proviso that the Master Servicer shall not be
required to expend its own funds in connection with any foreclosure or towards
the restoration of any property unless it determines in good faith (i) that such
restoration or foreclosure 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 either through
Liquidation Proceeds (respecting which it shall have priority for purposes of
reimbursements from the Certificate Account pursuant to Section 4.03) or through
Insurance Proceeds (respecting which it shall have similar priority). 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), and in
respect of the Master Servicer only, to receive Excess Liquidation Proceeds (to
the extent not otherwise payable to the holders of the Subordinate Certificates
pursuant to Section 6.03(i)) as additional servicing compensation to the extent
that transfers or withdrawals from the Certificate Account with respect thereto
are permitted under Section 4.03. Any income from or other funds (net of any
income taxes) generated by REO Property shall be deemed for purposes of this
Agreement to be Insurance Proceeds.

                  (b) The Trust Fund shall not acquire any real property (or any
personal property incident to such real property) except in connection with a
default or imminent default of a Mortgage Loan. In the event that the Trust Fund
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 Trust Fund within before the close of the
third taxable year following the year of its acquisition by the Trust Fund
unless the Trustee shall have received a REMIC Opinion with respect to such
longer retention or the Master Servicer applies for and receives an extension of
the three-year period under Section 856(e)(3) of the Code, in which case such
three year period will be extended by the period set forth in such REMIC Opinion
or approved application, as the case may be. The Trustee shall have no
obligation to pay for such REMIC Opinion.

                  Section 3.13. TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES.
(a) Upon payment in full of any Mortgage Loan or the receipt by the Master
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Master Servicer will immediately notify the
Trustee by a certification signed by a Servicing Officer in the Form of Exhibit
D (which certification shall include a statement to the effect that all amounts
received or to be received in


                                      III-9

<PAGE>



connection with such payment which are required to be deposited in the
Certificate Account have been or will be so deposited in the appropriate
subaccount thereof) and shall request delivery to the Master Servicer or a
Sub-Servicer, as the case may be, of the Mortgage File. Upon receipt of such
certification and request, the Trustee shall promptly release the related
Mortgage File to the Master Servicer or a Sub-Servicer and execute and deliver
to the Master Servicer, without recourse, the request for reconveyance, deed of
reconveyance or release or satisfaction of mortgage or such instrument releasing
the lien of the Security Instrument (furnished by the Master Servicer), together
with the Mortgage Note with written evidence of cancellation thereon. No
expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Certificate Account.

                  (b) From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan or collection under a Required Insurance
Policy, the Master Servicer shall deliver to the Trustee a Request for Release
signed by a Servicing Officer on behalf of the Master Servicer in substantially
the form attached as Exhibit D hereto. Upon receipt of the Request for Release,
the Trustee shall deliver the Mortgage File or any document therein to the
Master Servicer or Sub- Servicer, as the case may be.

                  (c) The Master Servicer shall cause each Mortgage File or any
document therein released pursuant to Subsection 3.13(b) to be returned to the
Trustee when the need therefor no longer exists, and in any event within 21 days
of the Master Servicer's receipt thereof, unless the Mortgage Loan has become a
Liquidated Mortgage Loan and the Liquidation Proceeds relating to the Mortgage
Loan have been deposited in the appropriate subaccount of the Certificate
Account or such Mortgage File is being used to pursue foreclosure or other legal
proceedings. Prior to return of a Mortgage File or any document to the Trustee,
the Master Servicer, the related Insurer or Sub- Servicer to whom such file or
document was delivered shall retain such file or document in its respective
control unless the Mortgage File or such document has been delivered to an
attorney, or to a public trustee or other public official as required by law, to
initiate or pursue legal action or other proceedings for the foreclosure of the
Mortgaged Property either judicially or non-judicially, and the Master Servicer
has delivered to the Trustee a certificate of a Servicing Officer certifying as
to the name and address of the Person to which such Mortgage File or such
document was delivered and the purpose or purposes of such delivery. If a
Mortgage Loan becomes a Liquidated Mortgage Loan, the Master Servicer shall
deliver the Request for Release with respect thereto to the Trustee upon deposit
of the related Liquidation Proceeds in the appropriate subaccount of the
Certificate Account.

                  (d) The Trustee shall execute and deliver to the Master
Servicer any court pleadings, requests for trustee's sale or other documents
necessary to (i) the foreclosure or trustee's sale with respect to a Mortgaged
Property; (ii) any legal action brought to obtain judgment against any Mortgagor
on the Mortgage Note or Security Instrument; (iii) obtain a deficiency judgment
against the Mortgagor; or (iv) enforce any other rights or remedies provided by
the Mortgage Note or Security Instrument or otherwise available at law or
equity. Together with such documents or pleadings the Master Servicer shall
deliver to the Trustee a certificate of a Servicing Officer in which it requests
the Trustee to execute the pleadings or documents. The certificate shall certify
and explain the reasons for which the pleadings or documents are required. It
shall further certify that the Trustee's execution and delivery of the pleadings
or documents will not invalidate any insurance coverage under the Required
Insurance Policies or invalidate or otherwise affect the lien of the


                                     III-10

<PAGE>



Security Instrument, except for the termination of such a lien upon completion
of the foreclosure or trustee's sale.

                  Section 3.14. SERVICING AND MASTER SERVICING COMPENSATION. (a)
As compensation for its activities hereunder, the Master Servicer shall be
entitled to receive the Master Servicing Fee from full payments of accrued
interest on each Mortgage Loan.

                  (b) The Master Servicer may retain additional servicing
compensation in the form of prepayment charges, if any, assumption fees, tax
service fees, fees for statement of account or payoff, late payment charges,
interest on amounts deposited in any Accounts or Permitted Investments of such
amounts, or otherwise, and with respect to any Due Date, any interest paid on
Simple Interest Loans in excess of 30 days of interest. The Master Servicer is
also entitled to receive Excess Liquidation Proceeds as additional servicing
compensation to the extent that transfers or withdrawals from the appropriate
subaccount of the Certificate Account with respect thereto are permitted under
Subsection 4.03(a)(xi) and are not otherwise payable to the holders of the
Subordinate Certificates pursuant to Section 6.03(i). The Master Servicer shall
be required to pay all expenses it incurs in connection with servicing
activities under this Agreement, including fees and expenses to Sub-Servicers,
and shall not be entitled to reimbursement except as provided in this Agreement.
Expenses to be paid by the Master Servicer under this Subsection 3.14(b) shall
include payment of the expenses of the accountants retained pursuant to Section
3.16.

                  Section 3.15. ANNUAL STATEMENT OF COMPLIANCE. Within 120 days
after June 30th of each year, commencing June 1999, the Master Servicer at its
own expense, shall deliver to the Trustee, with a copy to the Rating Agencies,
an Officer's Certificate stating, as to the signer thereof, that (i) a review of
the activities of the Master Servicer during the preceding fiscal year or
applicable portion thereof and of performance under this Agreement has been made
under such officer's supervision, (ii) to the best of such officer's knowledge,
based on such review, the Master Servicer has fulfilled all its obligations
under this Agreement for 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 including the steps being taken by the
Master Servicer to remedy such default; (iii) a review of the activities of each
Sub-Servicer, if any, during the Sub-Servicer's most recently ended fiscal year
on or prior to such June 30th and its performance under its Sub-Servicing
Agreement has been made under such Officer's supervision; and (iv) to the best
of the Servicing Officer's knowledge, based on his review and the certification
of an officer of the Sub-Servicer (unless the Servicing Officer has reason to
believe that reliance on such certification is not justified), either each
Sub-Servicer has performed and fulfilled its duties, responsibilities and
obligations under this Agreement and its Sub-Servicing Agreement in all material
respects throughout the year, or, if there has been a default in performance or
fulfillment of any such duties, responsibilities or obligations, specifying the
nature and status of each such default known to the Servicing Officer. Copies of
such statements shall be provided by the Master Servicer to the
Certificateholders upon request or by the Trustee at the expense of the Master
Servicer should the Master Servicer fail to provide such copies.

                  Section 3.16. ANNUAL INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING
REPORT. (a) Within 120 days after June 30th of each year, commencing June, 1999,
the Master Servicer, at its expense, shall cause a firm of Independent public
accountants who are members of the American


                                     III-11

<PAGE>



Institute of Certified Public Accountants to furnish a statement to the Master
Servicer, which will be provided to the Trustee and the Rating Agencies to the
effect that, in connection with the firm's examination of the Master Servicer's
financial statements as of the end of such fiscal year, nothing came to their
attention that indicated that the Master Servicer was not in compliance with
Sections 3.07, 3.15, 4.01, 4.02, 4.03 and 4.04 except for (i) such exceptions as
such firm believes to be immaterial and (ii) such other exceptions as are set
forth in such statement. In connection with the engagement to deliver any such
report (or other accountants' report or certificate hereunder) the Trustee is
authorized and directed to enter into such agreed-upon-procedures or engagement
letter as such accountants may request and shall be indemnified hereunder in so
doing.

                  (b) Within 120 days after the last day of the fiscal year of
each Sub-Servicer or a Master Servicer other than EMC or the Trustee, commencing
in 1998, the Master Servicer, at its expense, shall furnish to the Trustee the
most recently available letter or letters from one or more firms of Independent
certified public accountants who are members of the American Institute of
Certified Public Accountants reporting the results of such firm's examination of
the servicing procedures of any Sub-Servicer and any Master Servicer (other than
EMC or the Trustee) in accordance with the requirements of the Uniform Single
Attestation Program for Mortgage Bankers.

                  Section 3.17. REMIC-RELATED COVENANTS. For as long as the
REMIC shall exist, the Master Servicer and the Trustee shall act in accordance
herewith to assure continuing treatment of the REMIC as a REMIC, and the Trustee
shall comply with any directions of the Master Servicer to assure such
continuing treatment. In particular, the Trustee shall not (a) sell or permit
the sale of all or any portion of the Mortgage Loans or of any Permitted
Investment unless such sale is as a result of a repurchase of the Mortgage Loans
pursuant to this Agreement or the Trustee has received a REMIC Opinion prepared
at the expense of the Trust Fund; and (b) other than with respect to a
substitution pursuant to Section 2.05, accept any contribution to the REMIC
after the Startup Day without receipt of a REMIC Opinion.

                  Section 3.18. ADDITIONAL INFORMATION. The Master Servicer
agrees to furnish the Seller from time to time upon reasonable request, such
further information, reports and financial statements as the Seller deems
appropriate to prepare and file all necessary reports with the Securities and
Exchange Commission.

                  Section 3.19. OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.
The Master Servicer shall have the right, but not the obligation, to purchase
any Defaulted Mortgage Loan for a price equal to the Repurchase Price therefor.
Any such purchase shall be accomplished as provided in Subsection 2.02(c)
hereof.

                                   ARTICLE IV

                                    Accounts

                  Section 4.01. PROTECTED ACCOUNTS. (a) The Master Servicer
shall establish and maintain if it is servicing the Mortgage Loans and shall
require each Sub-Servicer to establish and maintain a Protected Account
complying with the requirements set forth in this Section 4.01, with records to
be kept with respect thereto on a Mortgage Loan by Mortgage Loan basis, into
which accounts shall be deposited within 24 hours of receipt all collections of
principal and interest on any Mortgage Loan and with respect to any REO Property
received by the Master Servicer, or a Sub- Servicer, including Principal
Prepayments, Insurance Proceeds, Liquidation Proceeds, and advances made from
the Sub-Servicer's own funds (less servicing compensation as permitted by
Subsection 3.14(a)) and all other amounts to be deposited in the Protected
Accounts. The Master Servicer is hereby authorized to make withdrawals from and
deposits to the related Protected Accounts for purposes required or permitted by
this Agreement. All Protected Accounts shall be held in a Designated Depository
Institution and segregated on the books of such institution. The amount at any
time credited to a Protected Account shall be fully insured by the FDIC or, to
the extent that such balance exceeds the lesser of $100,000 or the limits of
such insurance, such excess must be transferred to the appropriate subaccount of
the Certificate Account or the related Custody Account or invested in Permitted
Investments.

                  Amounts on deposit in a Protected Account may be invested in
Permitted Investments, such Permitted Investments to mature, or to be subject to
redemption or withdrawal, no later than the date on which such funds are
required to be withdrawn for deposit in the Custody Account or Certificate
Account, and shall be held until required for such deposit. The income earned
from Permitted Investments made pursuant to this Section 4.01 shall be paid to
the Master Servicer or the related Sub-Servicer as additional compensation for
its obligations under this Agreement, and the risk of loss of moneys required to
be distributed to the Certificateholders resulting from such investments shall
be borne by and be the risk of the Master Servicer or the related Sub-Servicer.
The Master Servicer shall, itself, or cause the related Sub-Servicer to, deposit
the amount of any such loss in the related Protected Account within two Business
Days of receipt of notification of such loss but not later than the second
Business Day prior to the Distribution Date on which the moneys so invested are
required to be distributed to the Certificateholders. The Master Servicer may,
and the Master Servicer may permit a Sub-Servicer to, transfer funds to other
accounts (which shall for purposes hereof be deemed to be Protected Accounts) or
to establish Protected Accounts not conforming to the foregoing requirements, to
the extent that such other accounts or Protected Accounts are Rating Agency
Eligible Accounts.

                  (b) On or before each Funds Transfer Date, the Master Servicer
shall withdraw or shall cause (by written direction to the Trustee if such
withdrawal is from a Custody Account) to be withdrawn from the Protected
Accounts or the Custody Account and shall immediately deposit or cause to be
deposited in the appropriate subaccount of the Certificate Account amounts
representing the following collections and payments (other than with respect to
principal of or interest on the Mortgage Loans due on or before the Cut-off
Date):



                                      IV-1

<PAGE>



                           (i) Scheduled Payments on the related Mortgage Loans
                  (other than Simple Interest Loans) received or any portion
                  thereof advanced by the Master Servicer or Sub-Servicers which
                  were due on or before the related Due Date (including any
                  amount required to be paid by the Master Servicer in respect
                  of interest on Simple Interest Loans) and actual payments on
                  Simple Interest Loans received during the related Prepayment
                  Period, net of the amount thereof comprising the Master
                  Servicing Fee due the Master Servicer;

                           (ii) Full Principal Prepayments and any Liquidation
                  Proceeds received by the Master Servicer or Sub-Servicers with
                  respect to such Mortgage Loans in the related Prepayment
                  Period, with interest to the date of prepayment or
                  liquidation, net of the amount thereof comprising the Master
                  Servicing Fee due the Master Servicer;

                           (iii) Partial prepayments of principal received by
                  the Master Servicer or Sub-Servicers for such Mortgage Loans
                  in the related Prepayment Period; and

                           (iv) Any amount to be used as a Certificate Account
Advance.

                  (c) Withdrawals may be made from a Protected Account only to
make remittances as provided in Subsections 4.01(b) or 4.03(c), or Section 4.04;
to reimburse the Master Servicer or a Sub-Servicer for advances of principal and
interest which have been recovered by subsequent collection from the related
Mortgagor; to remove amounts deposited in error; to remove fees, charges or
other such amounts deposited on a temporary basis; or to clear and terminate the
account at the termination of this Agreement in accordance with Section 10.01.

                  (d) The Master Servicer shall deliver to the Trustee on or
prior to the Determination Date in each month a statement from the institution
at which each Protected Account is maintained showing deposits and withdrawals
during the prior month.

                  Section 4.02. CERTIFICATE ACCOUNT. (a) The Trustee shall
establish and maintain in the name of the Trustee, for the benefit of the
Certificateholders, the Certificate Account as a segregated non-interest bearing
trust account or accounts. The Certificate Account shall have five separate
subaccounts, one each for all funds with respect to each Mortgage Loan Group.
The Trustee will deposit in the appropriate subaccount as identified by the
Master Servicer, of the Certificate Account as received the following amounts:

                           (i) Any amounts withdrawn from a Protected Account
                  pursuant to Subsection 4.01(b) or the Custody Account pursuant
                  to Section 4.04;

                           (ii) Any Monthly Advance and any Compensating
                  Interest Payments and any payments required to be made by the
                  Master Servicer with respect to Simple Interest Loans which
                  were not deposited in the Protected Account;

                           (iii) Any Insurance Proceeds or Liquidation Proceeds
                  received by the Master Servicer which were not deposited in a
                  Protected Account or the Custody Account;

                           (iv) The Repurchase Price with respect to any
                  Mortgage Loans purchased by BSMCC pursuant to Sections 2.02 or
                  2.03 or by the Master Servicer pursuant to Section 3.19, any
                  amounts which are to be treated pursuant to Section 2.05 as
                  the payment of such a Repurchase Price, and all proceeds of
                  any Mortgage Loans or property acquired with respect thereto
                  repurchased by the Seller or its designee pursuant to Section
                  10.01;

                           (v) Any amounts required to be deposited with respect
                  to losses on Permitted Investments pursuant to Subsection
                  4.02(d) or Section 4.04(d) below; and

                           (vi) Any other amounts received by the Master
                  Servicer or the Trustee and required to be deposited in such
                  subaccount of the Certificate Account pursuant to
                  this Agreement.

                  (b) All amounts deposited to the Certificate Account shall be
held by the Trustee in the name of the Trustee in trust for the benefit of the
Certificateholders in accordance with the terms and provisions of this
Agreement, subject to the right of the Master Servicer to require the Trustee to
make withdrawals therefrom as provided herein. The foregoing requirements for
crediting the Certificate Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of (i) prepayment or late payment charges or assumption, tax service,
statement account or payoff, substitution, satisfaction, release and other like
fees and charges and (ii) the items enumerated in subsections 4.03(a)(i), (ii),
(iii), (iv), (vi), (vii), (ix) and (xi) need not be credited by the Master
Servicer or the related Sub-Servicer to the Certificate Account and may be
retained by the Master Servicer or the related Sub-Servicer as additional
servicing compensation. In the event that the Master Servicer shall deposit or
cause to be deposited to the Certificate Account any amount not required to be
credited thereto, or shall deposit or cause to be deposited to a subaccount of
the Certificate Account any amount which should appropriately be credited to
another subaccount of the Certificate Account, the Trustee, upon receipt of a
written request therefor signed by a Servicing Officer of the Master Servicer,
shall promptly transfer such amount to the Master Servicer or to the appropriate
other subaccount of the Certificate Account, as applicable, any provision herein
to the contrary notwithstanding.

                  (c) The Certificate Account shall constitute a trust account
of the Trust Fund segregated on the books of the Trustee and held by the Trustee
in trust, and the Certificate Account and the funds deposited therein shall not
be subject to, and shall be protected from, all claims, liens, and encumbrances
of any creditors or depositors of the Trustee or the Master Servicer (whether
made directly, or indirectly through a liquidator or receiver of the Trustee or
the Master Servicer). The amount at any time credited to the Certificate Account
shall be (i) fully insured by the FDIC to the maximum coverage provided thereby,
(ii) at the written direction of the Master Servicer invested, in the name of
the Trustee, or its nominee, for the benefit of the Certificateholders, in such
Permitted Investments to be held by the Trustee as the Master Servicer may
direct (such direction to be confirmed in writing) and in the absence of such
direction, the Trustee shall invest funds in the Certificate Account in
Permitted Investments described in clause (viii) of the definition thereof, or
(iii) from the maturity of any Permitted Investment on the Business Day prior to
a Distribution Date through the distribution of such funds on such Distribution
Date or at such other time and in such


                                      IV-3

<PAGE>



amount as, in the judgment of the Master Servicer, cannot reasonably be invested
in accordance with items (i) or (ii) of this sentence, held by the Trustee in
such Certificate Account. All Permitted Investments shall mature or be subject
to redemption or withdrawal on or before, and shall be held until, the next
succeeding Distribution Date if the obligor for such Permitted Investment is the
Trustee or, if such obligor is any other Person, the Business Day preceding such
Distribution Date. With respect to the Certificate Account and the funds
deposited therein, the Trustee shall take such action as may be necessary to
ensure that the Certificateholders shall be entitled to the priorities afforded
to such a trust account (in addition to a claim against the estate of the
Trustee) as provided by 12 U.S.C. ss. 92a(e), if applicable, or any applicable
comparable state statute applicable to state chartered banking corporations.

                  (d) The income earned from Permitted Investments made pursuant
to this Section 4.02 shall be paid to the Master Servicer, as additional
compensation for its obligations under this Agreement, and the risk of loss of
moneys required to be distributed to the Certificateholders resulting from such
investments shall be borne by and be the risk of the Master Servicer. The amount
of any such loss shall be remitted by the Master Servicer to the Trustee for
deposit in the Certificate Account within two Business Days of receipt of
notification of such loss but not later than the second Business Day prior to
the Distribution Date on which the moneys so invested are required to be
distributed to the Certificateholders.

                  Section 4.03. PERMITTED WITHDRAWALS AND TRANSFERS FROM THE
CERTIFICATE Account. (a) The Trustee will, from time to time on demand of the
Master Servicer, make or cause to be made such withdrawals or transfers from the
appropriate subaccount of the Certificate Account as the Master Servicer has
designated for such transfer or withdrawal as specified in a certificate signed
by a Servicing Officer (upon which the Trustee may conclusively rely) for the
following purposes:

                           (i) to reimburse the Master Servicer or any
                  Sub-Servicer for any Monthly Advance of its own funds or any
                  advance of such Sub-Servicer's own funds, the right of the
                  Master Servicer or a Sub-Servicer to reimbursement pursuant to
                  this subclause (i) being limited to amounts received on a
                  particular Mortgage Loan (including, for this purpose, the
                  Repurchase Price therefor, Insurance Proceeds and Liquidation
                  Proceeds) which represent late payments or recoveries of the
                  principal of or interest on such Mortgage Loan respecting
                  which such Monthly Advance or advance was made;

                           (ii) to reimburse the Master Servicer or any
                  Sub-Servicer from Insurance Proceeds or Liquidation Proceeds
                  relating to a particular Mortgage Loan for amounts expended by
                  the Master Servicer or such Sub-Servicer pursuant to Section
                  3.12 in good faith in connection with the restoration of the
                  related Mortgaged Property which was damaged by an Uninsured
                  Cause or in connection with the liquidation of such Mortgage
                  Loan;

                           (iii) to reimburse the Master Servicer or any
                  Sub-Servicer from Insurance Proceeds relating to a particular
                  Mortgage Loan for Insured Expenses incurred with respect to
                  such Mortgage Loan and to reimburse the Master Servicer or
                  such Sub- Servicer from Liquidation Proceeds from a particular
                  Mortgage Loan for Liquidation

                  Expenses incurred with respect to such Mortgage Loan; PROVIDED
                  THAT the Master Servicer shall not be entitled to
                  reimbursement for Liquidation Expenses with respect to a
                  Mortgage Loan to the extent that (x) any amounts with respect
                  to such Mortgage Loan were paid as Excess Liquidation Proceeds
                  pursuant to clause (xi) of this Subsection 4.03(a) to the
                  Master Servicer; and (y) such Liquidation Expenses were not
                  included in the computation of such Excess Liquidation
                  Proceeds;

                           (iv) to pay the Master Servicer or any Sub-Servicer
                  (payment to any Sub- Servicer to be subject to prior payment
                  to the Master Servicer of an amount equal to the Master
                  Servicing Fee), as appropriate, from Liquidation Proceeds or
                  Insurance Proceeds received in connection with the liquidation
                  of any Mortgage Loan, the amount which it or such Sub-Servicer
                  would have been entitled to receive under subclause (ix) of
                  this Subsection 4.03(a) as servicing compensation on account
                  of each defaulted scheduled payment on such Mortgage Loan if
                  paid in a timely manner by the related Mortgagor, but only to
                  the extent that the aggregate of Liquidation Proceeds and
                  Insurance Proceeds with respect to such Mortgage Loan, after
                  any reimbursement to the Master Servicer or any Sub-Servicer,
                  pursuant to subclauses (i), (ii), (iii) and (vi) of this
                  Subsection 4.03(a), exceeds the Outstanding Principal Balance
                  of such Mortgage Loan plus accrued and unpaid interest thereon
                  at the related Mortgage Interest Rate less the Master
                  Servicing Fee Rate to but not including the date of payment;

                           (v) to pay the Master Servicer or any Sub-Servicer
                  (payment to any Sub- Servicer to be subject to prior payment
                  to the Master Servicer of the portion of the Master Servicing
                  Fee which the Master Servicer is entitled to retain as
                  evidenced in writing to the Trustee by the Master Servicer, as
                  appropriate, from the Repurchase Price for any Mortgage Loan,
                  the amount which it or such Sub-Servicer would have been
                  entitled to receive under subclause (ix) of this Subsection
                  4.03(a) as servicing compensation, but only to the extent that
                  the Repurchase Price with respect to such Mortgage Loan after
                  any reimbursement to the related Master Servicer and Sub-
                  Servicer pursuant to subclauses (i) and (vi) of this
                  Subsection 4.03(a) exceeds the Outstanding Principal Balance
                  of such Mortgage Loan plus accrued and unpaid interest thereon
                  at the related Mortgage Interest Rate less the Master
                  Servicing Fee Rate through the last day of the month of
                  repurchase;

                           (vi) to reimburse the Master Servicer or any
                  Sub-Servicer for advances of funds pursuant to Sections 3.07,
                  3.09 and 3.10, the right to reimbursement pursuant to this
                  subclause being limited to amounts received on the related
                  Mortgage Loan (including, for this purpose, the Repurchase
                  Price therefor, Insurance Proceeds and Liquidation Proceeds)
                  which represent late recoveries of the payments for which such
                  advances were made;

                           (vii) to pay the Master Servicer or any Sub-Servicer,
                  as the case may be, with respect to each Mortgage Loan that
                  has been purchased pursuant to Section 2.02, 2.03, 2.05, 3.19
                  or 10.01, all amounts received thereon, representing
                  recoveries of principal that reduce the Outstanding Principal
                  Balance of the related Mortgage

                  Loan below the Outstanding Principal Balance used in
                  calculating the Repurchase Price or representing interest
                  included in the calculation of the Repurchase Price or accrued
                  after the end of the month during which such repurchase
                  occurs;

                           (viii) to reimburse the Master Servicer or any
                  Sub-Servicer for any Monthly Advance or advance, after a
                  Realized Loss has been allocated with respect to the related
                  Mortgage Loan if the Monthly Advance or advance has not been
                  reimbursed pursuant to clauses (i) and (vi), such
                  reimbursement to come from the subaccount relating to the
                  Mortgage Loan Group of which the related Mortgage Loan is a
                  part;

                           (ix) to pay the Master Servicer and any Sub-Servicer
                  servicing compensation as set forth in Section 3.14, including
                  amounts due to it with respect to excess interest received on
                  Simple Interest Loans;

                  costs and liabilities incurred by and reimbursable to it
                  pursuant to Subsection 7.04(d), which, if not specifically
                  allocable to a Mortgage Loan Group, shall be allocated between
                  the subaccounts, PRO RATA, based on the Scheduled Principal
                  Balances of the Group I Mortgage Loans, the Group II Mortgage
                  Loans, the Group III Mortgage Loans, the Group IV Mortgage
                  Loans and the Group V Mortgage Loans, respectively;

                           (xi) to pay to the Master Servicer, as additional
                  servicing compensation, any Excess Liquidation Proceeds not
                  paid to the holders of the Subordinate Certificates pursuant
                  to Section 6.01(i);

                           (xii) to pay to the holders of the Subordinate

                  Section 6.01(i);

                           (xiii) to clear and terminate the Certificate Account
                  pursuant to Section 10.01; and

                           (xiv) to remove amounts deposited in error.

                  The Master Servicer shall keep and maintain separate
accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of
accounting for any reimbursement from the Certificate Account pursuant to
subclauses (i) through (vi), inclusive, and (viii) or with respect to any such
amounts which would have been covered by such subclauses had the amounts not
been retained by the Master Servicer without being deposited in the Certificate
Account under Section 4.02(b).

                  (b) On each Distribution Date, the Trustee shall make the
following payments in the priority set forth from the funds in the Certificate
Account:

                           (i) First, the Trustee's Fees and expenses pursuant
                   to Section 9.05 shall be paid to the Trustee; and



                                      IV-6

<PAGE>



                           (ii) Second, the amount distributable to the Holders
                  of the Certificates shall be payable in accordance with
                  Section 6.01.

                  (c) Notwithstanding the provisions of this Section 4.03, the
Master Servicer may, but is not required to, allow the Sub-Servicers to deduct
from amounts received by them or from the related Protected Account, prior to
deposit in the Certificate Account or the Custody Account, any portion to which
such Sub-Servicers are entitled as servicing compensation (including income on
Permitted Investments) or reimbursement of any reimbursable advances made by
such Sub-Servicers.

                  Section 4.04. CUSTODY ACCOUNT. (a) The Trustee shall establish
and maintain for the benefit of the Certificateholders the Custody Account as a
segregated non-interest bearing trust account in the corporate trust department
of a Designated Depository Institution. The Custody Account shall constitute a
trust account of the Trust Fund segregated on the books of the Designated
Depository Institution and held by the Designated Depository Institution in
trust, and such Account and the funds deposited therein shall not be subject to,
and shall be protected from, all claims, liens, and encumbrances of any
creditors or depositors of the Designated Depository Institution, the Trustee,
the Master Servicer, any Sub-Servicer (whether made directly, or indirectly
through a liquidator or receiver of the Designated Depository Institution, the
Trustee, any Master Servicer, or any Sub-Servicer). With respect to the Custody
Account maintained with the Trustee and the funds deposited therein, the Trustee
shall take such action as may be necessary to ensure that the Certificateholders
shall be entitled to the priorities afforded to such a trust account (in
addition to a claim against the estate of the Trustee) as provided by 12 U.S.C.
ss. 92a(e), if applicable, or any applicable comparable state statute applicable
to state chartered banking corporations. The Custody Account shall be an outside
reserve fund of REMIC II and shall not constitute a part of REMIC II (or REMIC
I). The Trustee shall be the legal owner of the portion of the Funds held in the
Custody Account for the benefit of the Certificateholders and for all Federal
income tax purposes, the Master Servicer shall be the owner of the Custody
Account. For all Federal tax purposes, amounts, if any, transferred by REMIC II
to the Custody Account shall be treated as amounts distributed by REMIC II to
the Master Servicer.

                  (b) Within one Business Day after receipt, the Master Servicer
shall withdraw or shall cause to be withdrawn from each Protected Account and
shall immediately deposit or cause to be deposited in the Custody Account all
amounts in the Protected Account not otherwise invested in Permitted Investments
pursuant to Section 4.01 and exceeding the lesser of $100,000 or the FDIC
insurance limit (other than with respect to principal of or interest on the
Mortgage Loans due on or before the Cut-off Date).

                  (c) Withdrawals may be made from the Custody Account only to
make remittances as provided in Sections 4.01(b) or 4.04(d); to reimburse the
Master Servicer or any Sub- Servicer for advances of principal and interest
which have been recovered by subsequent collection from the related Mortgagor;
to remove amounts deposited in error; to remove fees, charges or other such
amounts deposited on a temporary basis; or to clear and terminate the account at
the termination of this Agreement in accordance with Section 10.01.

                  (d) Funds in the Custody Account may be invested at the
written direction of the Master Servicer (such direction to be confirmed
promptly in writing) in Permitted Investments held


                                      IV-7

<PAGE>



in trust for the benefit of the Certificateholders and in the absence of such
directions, funds in the Custody Account shall be invested in Permitted
Investments described in clause (viii) of the definition thereof. Such Permitted
Investments must mature, or be subject to redemption or withdrawal, no later
than the date on which such funds are required to be withdrawn for deposit in
the Certificate Account pursuant to Section 4.01(b) and shall be held in such
Account until required for such deposit. The income earned from Permitted
Investments made pursuant to this Section 4.04 shall be paid to the Master
Servicer as additional compensation for its obligations under this Agreement,
and the risk of loss of moneys required to be distributed to the
Certificateholders resulting from such investments shall be borne by and be the
risk of the Master Servicer. The amount of any such loss shall be deposited by
the Master Servicer in the Custody Account within two Business Days of receipt
of notification of such loss but not later than the second Business Day prior to
the Distribution Date on which the moneys so invested are required to be
distributed to the Certificateholders.

                                    ARTICLE V

                  Section 5.01. CERTIFICATES. (a) The Depository, the Seller and
the Trustee have entered into a Depository Agreement dated as of May 29, 1998
(the "Depository Agreement"). Except for the Physical Certificates and as
provided in Subsection 5.01(b), the Certificates shall at all times remain
registered in the name of the Depository or its nominee and at all times: (i)
registration of such Certificates may not be transferred by the Trustee except
to a successor to the Depository; (ii) ownership and transfers of registration
of such Certificates on the books of the Depository shall be governed by
applicable rules established by the Depository; (iii) the Depository may collect
its usual and customary fees, charges and expenses from its Depository
Participants; (iv) the Trustee shall deal with the Depository as representative
of such Certificate Owners of the respective Class of Certificates for purposes
of exercising the rights of Certificateholders under this Agreement, and
requests and directions for and votes of such representative shall not be deemed
to be inconsistent if they are made with respect to different Certificate
Owners; and (v) the Trustee may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants.

                  The Class B-4, Class B-5 and Class B-6 Certificates are
initially Physical Certificates. If at any time the Holders of all of the
Certificates of one or more such Classes request that the Trustee cause such
Class to become Book-Entry Certificates, the Trustee and the Seller will take
such action as may be reasonably required to cause the Depository to accept such
Class or Classes for trading.

                  All transfers by Certificate Owners of such respective Classes
of Book-Entry Certificates shall be made in accordance with the procedures
established by the Depository Participant or brokerage firm representing such
Certificate Owners. Each Depository Participant shall only transfer Book-Entry
Certificates of Certificate Owners it represents or of brokerage firms for which
it acts as agent in accordance with the Depository's normal procedures.

                  (b) If (i)(A) the Seller advises the Trustee in writing that
the Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Trustee or the Seller is unable to
locate a qualified successor within 30 days or (ii) the Seller at its option
advises the Trustee in writing that it elects to terminate the book-entry system
through the Depository, the Trustee shall request that the Depository notify all
Certificate Owners of the occurrence of any such event and of the availability
of definitive, fully registered Certificates (the "Definitive Certificates") to
Certificate Owners requesting the same. Upon surrender to the Trustee of the
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration, the Trustee shall issue the Definitive
Certificates. Neither the Seller, 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.

                  (c) REMIC II will be evidenced by (x) the REMIC II Regular
Certificates, which will be uncertificated and non-transferable and are hereby
designated as the "regular interests" in REMIC II and (y) the Class R-2
Certificate, which is hereby designated as the single "residual interest" in
REMIC II. Except as discussed below, principal and interest shall be payable to,
and shortfalls, losses and prepayments are allocable to, the REMIC II Regular
Certificates in the same

Trustee may sign and countersign temporary Certificates that are printed,
lithographed or typewritten, in authorized denominations for Certificates of
such Class, substantially of the tenor of the definitive Certificates in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers or authorized signatories
executing such Certificates may determine, as evidenced by their execution of
such Certificates. If temporary Certificates are issued, the Seller will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of Definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office of the Trustee, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Certificates, the

DTC Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of $25,000 and
in each case increments of $1.00 in excess thereof, except that one Certificate
of each such Class may be issued in a different amount so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Current Principal Amount of such Class on the Closing Date. On the Closing Date,
the Trustee shall execute and countersign Physical Certificates all in an
aggregate principal amount that shall equal the Current Principal Amount of such
Class on the Closing Date. The Class B-4, Class B-5 and Class B-6 Certificates
will be issued in certificated fully-registered form in minimum denominations of
$25,000 and increments


                                       V-4

of $1.00 in excess thereof, except that one Certificate of each such Class may
be issued in a different amount so that the sum of the denominations of all
outstanding Certificates of such Class shall equal the Current Principal Amount
of such Class on the Closing Date. Each Class of Global Certificates, if any,
shall be issued in fully registered form in minimum dollar denominations of
$25,000 and integral multiples of $1.00 in excess thereof, except that one
Certificate of each Class may be in a different denomination so that the sum of
the denominations of all outstanding Certificates of such Class shall equal the
Current Principal Amount of such Class on the Closing Date. On the Closing Date,
the Trustee shall execute and countersign (i) in the case of each Class of Class
A Certificates and the Class B-1, Class B-2 and Class B-3 Certificates, the
Certificate in the entire principal amount of the Class and (ii) in the case of
the Class B-4, Class B-5 and Class B-6 Certificates, Individual Certificates all
in an aggregate principal amount that shall equal the Current Principal Amount
of each such Class on the Closing Date. The Certificates referred to in clause
(i) and if at any time there are to be Global Certificates, the Global
Certificates shall be delivered by the Seller to the Depository or pursuant to
the Depository's instructions, shall be delivered by the Seller on behalf of the
Depository to and deposited with the DTC Custodian. The Class R-1 and Class R-2
Certificates shall be issued in certificated fully-registered form in the
denomination of $50 each. The Trustee shall sign them by facsimile or manual
signature and countersign them by manual signature on behalf of the Trustee by
one or more authorized signatories, each of whom shall be Responsible Officers
of the Trustee or its agent. A Certificate bearing the manual and facsimile
signatures of individuals who were the authorized signatories of the Trustee or
its agent at the time of issuance shall bind the Trustee, notwithstanding that
such individuals or any of them have ceased to hold such positions prior to the
delivery of such Certificate.

                  (h) No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
the manually executed countersignature of the Trustee or its agent, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates issued on the Closing Date shall be dated the Closing Date. All
Certificates issued thereafter shall be dated the date of their
countersignature.

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

                  (j) For federal income tax purposes, each REMIC shall have a
tax year that is a calendar year and shall report income on an accrual basis.

                  (k) The Trustee shall cause each REMIC to elect to be treated
as a REMIC under Section 860D of the Code. Any inconsistencies or ambiguities in
this Agreement or in the administration of any Trust established hereby shall be
resolved in a manner that preserves the validity of such elections.

                  Trustee in writing that the Certificate is being transferred

                  Letter (and the Trustee shall be fully protected in so doing),
                  provided that, if based upon an Opinion of Counsel to the
                  effect that the delivery of (x) and (y) above are not
                  sufficient to confirm that the proposed transfer is being made

                  to, the registration requirements of the Securities Act and
                  other applicable laws, the Trustee shall as a condition of the

                  information prior to registering the transfer of an Individual
                  Certificate as shall be set forth in such Opinion of Counsel.

                  Accredited Investor, such transferee shall be required to take
                  delivery in the form of an Individual Certificate or
                  Certificates and the Trustee shall register such transfer only

                  takes delivery in the form of an Individual Certificate or
                  Certificates of such Class, except as set forth in clause (i)

                           (iii) In the case of an Individual Certificate of a
                  Class being transferred to a transferee that takes delivery in
                  the form of a beneficial interest in a Global Certificate of
                  such Class, the Trustee shall register such transfer if the

                  Individual Certificate of a Class for a beneficial interest in
                  a Global Certificate of such Class as provided herein, the
                  Trustee shall cancel such Individual Certificate and shall (or
                  shall request the Depository to) endorse on the schedule
                  affixed to the applicable Global Certificate (or on a

                  Certificate and made a part thereof) or otherwise make in its
                  books and records an appropriate notation evidencing the date
                  of such exchange or transfer and an increase in the

                  balance of such Individual Certificate exchanged or

                  (ii) Upon acceptance for exchange or transfer of a beneficial
                  interest in a Global Certificate of a Class for an Individual
                  Certificate of such Class as provided herein, the Trustee
                  shall (or shall request the Depository to) endorse on the
                  schedule affixed to such Global Certificate (or on a
                  continuation of such schedule affixed to such Global
                  Certificate and made a part thereof) or otherwise make in its
                  books and records an appropriate notation evidencing the date
                  of such exchange or transfer and a decrease in the certificate
                  balance of such Global Certificate equal to the certificate
                  balance of such Individual Certificate issued in exchange
                  therefor or upon transfer thereof.

                  (g) The Securities Legend shall be placed on any Individual
Certificate issued in exchange for or upon transfer of another Individual
Certificate or of a beneficial interest in a Global
Certificate.

                  (h) Subject to the restrictions on transfer and exchange set
forth in this Section 5.02, the holder of any Individual Certificate may
transfer or exchange the same in whole or in part (in an initial certificate
balance equal to the minimum authorized denomination or any integral multiple of
$1.00 in excess thereof) by surrendering such Certificate at the Corporate Trust
Office, or at the office of any transfer agent, together with an executed
instrument of assignment and transfer satisfactory in form and substance to the
Trustee in the case of transfer and a written request for exchange in the case
of exchange. The holder of a beneficial interest in a Global Certificate may,
subject to the rules and procedures of the Depository, cause the Depository (or
its nominee) to notify the Trustee in writing of a request for transfer or
exchange of such beneficial interest for an Individual Certificate or
Certificates. Following a proper request for transfer or exchange, the Trustee
shall, within five Business Days of such request made at such Corporate Trust
Office, sign, countersign and deliver at such Corporate Trust Office, to the
transferee (in the case of transfer) or holder (in the case of exchange) or send
by first class mail at the risk of the transferee (in the case of transfer) or
holder (in the case of exchange) to such address as the transferee or holder, as
applicable, may request, an Individual Certificate or Certificates, as the case
may require, for a like aggregate Fractional Undivided Interest and in such
authorized denomination or denominations as may be requested. The presentation
for transfer or exchange of any Individual Certificate shall not be valid unless
made at the Corporate Trust Office by the registered holder in person, or by a
duly authorized attorney-in-fact.

                  (i) At the option of the Certificateholders, Certificates may
be exchanged for other Certificates of authorized denominations of a like Class
and aggregate Fractional Undivided Interest, upon surrender of the Certificates
to be exchanged at any such office or agency; PROVIDED, HOWEVER, that no
Certificate may be exchanged for new Certificates unless the original Fractional
Undivided Interest represented by each such new Certificate (i) is at least
$25,000 with respect to the Certificates other than the Class R-1 and R-2
Certificates, which in each case shall be $50, or (ii) is acceptable to the
Seller as indicated to the Trustee in writing. Whenever any Certificates are so
surrendered for exchange, the Trustee shall sign and countersign and the Trustee
shall deliver the Certificates which the Certificateholder making the exchange
is entitled to receive.

                  (j) If the Trustee so requires, every Certificate presented or
surrendered for transfer or exchange shall be duly endorsed by, or be
accompanied by a written instrument of transfer, with a signature guarantee, in
form satisfactory to the Trustee, duly executed by the holder
thereof or his or her attorney duly authorized in writing.

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

                  (l) The Trustee shall cancel all Certificates surrendered for
transfer or exchange but shall retain such Certificates in accordance with its
standard retention policy or for such further time as is required by the record
retention requirements of the Securities Exchange Act of 1934, as amended, and
thereafter may destroy such Certificates.

                  (m) The following legend shall be placed on each Class B-1,
Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates, whether
upon original issuance or upon issuance of any other Certificate of any such
Class in exchange therefor or upon transfer thereof:

                  THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY
                  BY, OR ON BEHALF OF, AN EMPLOYEE BENEFIT PLAN OR OTHER
                  RETIREMENT ARRANGEMENT WHICH IS SUBJECT TO TITLE I OF THE
                  EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED,
                  AND/OR SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS
                  AMENDED, UNLESS THE PROPOSED TRANSFER AND/OR HOLDING OF A
                  CERTIFICATE AND THE SERVICING, MANAGEMENT AND/OR OPERATION OF
                  THE TRUST AND ITS ASSETS: (I) WILL NOT RESULT IN ANY
                  PROHIBITED TRANSACTION WHICH IS NOT COVERED UNDER AN
                  INDIVIDUAL OR CLASS PROHIBITED TRANSACTION EXEMPTION,
                  INCLUDING, BUT NOT LIMITED TO, PROHIBITED TRANSACTION
                  EXEMPTION ("PTE") 84-14, PTE 91-38, PTE 90-1, PTE 95-60, PTE
                  96-23 OR SECTION 401(C) OF ERISA AND THE REGULATIONS
                  PROMULGATED THEREUNDER AND (II) WILL NOT GIVE RISE TO ANY
                  ADDITIONAL FIDUCIARY DUTIES ON THE PART OF THE SELLER, THE
                  MASTER SERVICER OR THE TRUSTEE, WHICH WILL BE DEEMED
                  REPRESENTED BY AN OWNER OF A BOOK-ENTRY CERTIFICATE OR A
                  GLOBAL CERTIFICATE AND WILL BE EVIDENCED BY A REPRESENTATION
                  OR AN OPINION OF COUNSEL TO SUCH EFFECT BY OR ON BEHALF OF A
                  HOLDER OF A PRIVATE CERTIFICATE.

                  Section 5.03. MUTILATED, DESTROYED, LOST OR STOLEN
CERTIFICATES. (a) If (i) any mutilated Certificate is surrendered to the
Trustee, or the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate, and (ii) there is delivered to
the Trustee such security or indemnity as it may require to save it harmless,
and (iii) the Trustee has not received notice that such Certificate has been
acquired by a third Person, the Trustee shall sign, countersign and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a


                                       V-9

<PAGE>



new Certificate of like tenor and Fractional Undivided Interest but in each case
bearing a different number. The mutilated, destroyed, lost or stolen Certificate
shall thereupon be canceled of record by the Trustee and shall be of no further
effect and evidence no rights.

                  (b) Upon the issuance of any new Certificate under this
Section 5.03, the Trustee 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) connected
therewith. Any duplicate Certificate issued pursuant to this Section 5.03 shall
constitute complete and indefeasible evidence of ownership in the Trust Fund, as
if originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                  Section 5.04. PERSONS DEEMED OWNERS. Prior to due presentation
of a Certificate for registration of transfer, the Seller, the Master Servicer,
the Trustee and any agent of the Seller, the Master Servicer or the Trustee 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
6.01 and for all other purposes whatsoever. Neither the Seller, the Master
Servicer, the Trustee nor any agent of the Seller, the Master Servicer or the
Trustee shall be affected by notice to the contrary. No Certificate shall be
deemed duly presented for a transfer effective on any Record Date unless the
Certificate to be transferred is presented no later than the close of business
on the third Business Day preceding such Record Date.

                  Section 5.05. TRANSFER RESTRICTIONS ON RESIDUAL CERTIFICATES.
(a) Residual Certificates, or interests therein, may not be transferred without
the prior express written consent of the Tax Matters Person. As a prerequisite
to such consent, the proposed transferee must provide the Tax Matters Person and
the Trustee with an affidavit that the proposed transferee is not a Disqualified
Organization (as defined in Subsection 5.05(b)) (and, unless the Tax Matters
Person consents to the transfer to a person who is not a U.S. Person, an
affidavit that it is a U.S. Person) as provided in Subsection 5.05(b).

                  (b) No transfer, sale or other disposition of a Residual
Certificate (including a beneficial interest therein) may be made unless, prior
to the transfer, sale or other disposition of a Residual Certificate, the
proposed transferee (including the initial purchasers thereof) delivers to the
Tax Matters Person and the Trustee an affidavit in the form attached hereto as
Exhibit E stating, among other things, that as of the date of such transfer (i)
such transferee is not any of (A) the United States, any state or political
subdivision thereof, any foreign government, any international organization, or
any agency or instrumentality of any of the foregoing (other than an
instrumentality that is a corporation all of whose activities are subject to tax
under Chapter 1 of Subtitle A of the Code and (except in the case of FHLMC) a
majority of whose board of directors is not selected by the United States, or
any state or political subdivision thereof), (B) any organization that is exempt
from any tax imposed by Chapter 1 of Subtitle A of the Code, other than (x) a
tax-exempt farmers' cooperative within the meaning of Section 521 of the Code or
(y) an organization that is subject to the tax imposed by section 511 of the
Code on "unrelated business taxable income" or (C) a corporation operating on a
cooperative basis that is engaged in furnishing electric energy or providing
telephone service to persons in rural areas (within the meaning of Section
1381(a)(2)(C) of the Code) (any Person described in (A), (B), or (C) being
referred to herein as a "Disqualified Organization") and that (ii) such
transferee is not acquiring such Residual Certificate for the account


                                      V-10

<PAGE>



of a Disqualified Organization. The Tax Matters Person shall not consent to a
transfer of a Residual Certificate if it has actual knowledge that any statement
made in the affidavit issued pursuant to the preceding sentence is not true.
Notwithstanding any transfer, sale or other disposition of a Residual
Certificate to a Disqualified Organization, such transfer, sale or other
disposition shall be deemed to be of no legal force or effect whatsoever and
such Disqualified Organization shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. The Trustee
and the Tax Matters Person shall be under no liability to any Person for any
registration or transfer of a Residual Certificate that is not permitted by this
Subsection 5.05(b) or for making payments due on such Residual Certificate to
the purported Holder thereof or taking any other action with respect to such
purported Holder under the provisions of this Agreement so long as the written
affidavit referred to above was received with respect to such transfer, and the
Tax Matters Person and the Trustee had no knowledge that it was untrue. The
prior Holder shall be entitled to recover from any purported Holder of a
Residual Certificate that was in fact not a permitted transferee under this
Subsection 5.05(b) at the time it became a Holder all payments made on such
Residual Certificate. Each Holder of a Residual Certificate, by acceptance
thereof, shall be deemed for all purposes to have consented to the provisions of
this Subsection 5.05(b) and to any amendment of this Agreement deemed necessary
(whether as a result of new legislation or otherwise) by counsel of the Tax
Matters Person or the Seller to ensure that the Residual Certificates are not
transferred to a Disqualified Organization and that any transfer of such
Residual Certificates will not cause the imposition of a tax upon the Trust or
cause REMIC I or REMIC II to fail to qualify as a REMIC.

                  (c) Unless the Tax Matters Person shall have consented in
writing (which consent may be withheld in the Tax Matters Person's sole
discretion), the Residual Certificates (including a beneficial interest therein)
may not be purchased by or transferred to any person who is not a "United States
person," as such term is defined in Section 7701(a)(30) of the Code.

                  (d) By accepting a Residual Certificate, the purchaser thereof
agrees to be a Tax Matters Person, and appoints the Trustee to act as its agent
with respect to all matters concerning the
tax obligations of the Trust.

                  Section 5.06. RESTRICTIONS ON TRANSFERABILITY OF PRIVATE
CERTIFICATES. (a) No offer, sale, transfer or other disposition (including
pledge) of a Private Certificate shall be made by any Holder thereof unless
registered under the Securities Act, or an exemption from the registration
requirements of the Securities Act and any applicable state securities or "Blue
Sky" laws is available and the prospective transferee (other than the Seller) of
such Certificate signs and delivers to the Trustee an Investment Letter, if the
transferee is an Institutional Accredited Investor, in the form set forth as
Exhibit F-1 hereto, or a Rule 144A Certificate, if the transferee is a Qualified
Institutional Buyer, in the form set forth as Exhibit F-2 hereto. In the case of
a proposed transfer of a Private Certificate to a transferee other than a
Qualified Institutional Buyer, the Trustee may require an Opinion of Counsel
that such transaction is exempt from the registration requirements of the
Securities Act. The cost of such opinion shall not be an expense of the Trustee
or the Trust Fund.

                  (b) Each Class B-4, Class B-5 and Class B-6 Certificate shall
bear a Securities Legend.

                  Section 5.07. ERISA RESTRICTIONS. (a) Subject to the
provisions of subsection (b), no Class of Private Certificates may be acquired
directly or indirectly by, or on behalf of, an employee benefit plan or other
retirement arrangement which is subject to Title I of ERISA and/or Section 4975
of the Code, unless the proposed transferee provides a representation to the
Trustee (upon which the Trustee is authorized to rely) to the effect that the
proposed transfer and/or holding of a Certificate and the servicing, management
and operation of the Trust: (i) will not result in a prohibited transaction
under Section 406 of ERISA or Section 4975 of the Code which is not covered
under an individual or class prohibited transaction exemption including but not
limited to Department of Labor Prohibited Transaction Exemption ("PTE") 84-14
(Class Exemption for Plan Asset Transactions Determined by Independent Qualified
Professional Asset Managers); PTE 91-38 (Class Exemption for Certain
Transactions Involving Bank Collective Investment Funds); PTE 90-1 (Class
Exemption for Certain Transactions Involving Insurance Company Pooled Separate
Accounts), PTE 95-60 (Class Exemption for Certain Transactions Involving
Insurance Company General Accounts), and PTCE 96-23 (Class Exemption for Plan
Asset Transactions Determined by In-House Asset Managers); and Section 401(c) of
ERISA and the regulations to be promulgated thereunder (relating to insurance
company general accounts) and (ii) will not give rise to any additional
fiduciary duties under ERISA on the part of either the Seller, the Master
Servicer or the Trustee.

                  (b) Any Person acquiring an interest in a Book-Entry
Certificate or a Global Certificate which is a Subordinate Certificate, by
acquisition of such Certificate, shall be deemed to have represented to the
Trustee that it is either: (i) not acquiring an interest in such Certificate
directly or indirectly by, or on behalf of, an employee benefit plan or other
retirement arrangement which is subject to Title I of ERISA and/or Section 4975
of the Code, or (ii) such Person provides a representation, certification or an
opinion of counsel to the Trustee to the effect that the transfer and/or holding
of an interest in such Certificate and the servicing, management and/or
operation of the Trust and its assets: (I) will not result in any prohibited
transaction which is not covered under an individual or class prohibited
transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE
90-1, PTE 95-60, PTE 96-23 or Section 401(c) of ERISA and the regulations to be
promulgated thereunder and (II) will not give rise to any additional fiduciary
duties on the part of either the Seller, the Master Servicer or the Trustee.

                  Section 5.08. RULE 144A INFORMATION. For so long as any
Private Certificates are outstanding and are "restricted securities" within the
meaning of Rule 144(a)(3) of the Securities Act, (1) the Master Servicer will
provide or cause to be provided to any holder of such Certificates and any
prospective purchaser thereof designated by such a holder, upon the request of
such holder or prospective purchaser, the information required to be provided to
such holder or prospective purchaser by Rule 144A(d)(4) under the Securities
Act; and (2) the Master Servicer shall update such information from time to time
in order to prevent such information from becoming false and misleading and will
take such other actions as are necessary to ensure that the safe harbor
exemption from the registration requirements of the Securities Act under Rule
144A is and will be available for resales of such Certificates conducted in
accordance with Rule 144A.

                  occurring in June 2004 and the aggregate Current Principal
                  Amount of the Subordinate Certificates is more than 25% of the
                  initial aggregate principal amount of the Subordinate
                  Certificates, no such diversion of amounts of Principal
                  Prepayments otherwise due to the Subordinate Certificates in
                  accordance with (vi) above will be required to be made. In
                  addition, if on any Distribution Date on which the aggregate
                  Current Principal Amount of any Class or Classes of Class A
                  Certificates would be greater than the aggregate Scheduled
                  Principal Balance of the Mortgage Loans in its related
                  Mortgage Loan Group and any Class B Certificates are still
                  outstanding, in each case after giving effect to distributions
                  to be made on such Distribution Date, 100% of the Principal
                  Prepayments otherwise allocable to the Class B Certificates on
                  the Mortgage Loans in the other Mortgage Loan Groups will be
                  distributed to such Class or Classes of Class A Certificates
                  in reduction of the Current Principal Amounts thereof, until
                  the aggregate Current Principal Amount of such Class or
                  Classes of Class A Certificates is an amount equal to the
                  aggregate Scheduled Principal Balance of the Mortgage Loans in
                  its related Mortgage Loan Group.

                           (viii) On each Distribution Date, any Group Available

                  Classes of Certificates entitled thereto, as described above,
                  will be distributed to the Class R-2 Certificates; provided
                  that if

                  on any Distribution Date there are any Group Available Funds
                  remaining after payment of interest and principal to a Class
                  or Classes of Certificates entitled thereto, such Group
                  Available Funds will be distributed to the other Classes of
                  Class A Certificates, PRO RATA, based upon their Current
                  Principal Amounts, until all amounts due to all Classes of
                  Class A Certificates have been paid in full, before any such
                  remaining Group Available Funds are distributed to the Class
                  R-2 Certificates.

                           (b) On each Distribution Date, the funds available
         for distribution shall be allocated to distributions on the REMIC II
         Regular Interests in an amount sufficient to make the distributions on
         the respective Corresponding Classes of Certificates on such Payment
         Date in accordance with the provisions of subsection (a) of this
         Section 6.01.

                  (c) No Accrued Certificate Interest will be payable with
respect to any Class of Certificates after the Distribution Date on which the
outstanding principal balance of such Certificate
has been reduced to zero.

                  Section 6.02. ALLOCATION OF DEFERRED INTEREST.  (a)  On or
prior to each Determination Date, the Trustee shall determine the amount of any
Deferred Interest in respect of each Mortgage Loan that occurred during the
immediately preceding calendar month.

                  (b) With respect to any Distribution Date, any Deferred
Interest with respect to a Mortgage Loan will be allocated to increase the
Current Principal Amount of each related Class
of Certificates in the following manner:

         first, to the Class or Classes of Senior Certificates related to the
         Mortgage Loan Group containing such Mortgage Loan (PRO RATA based on
         Current Principal Amount in the case of the Class A-I, Class R-1 and
         Class R-2 Certificates) in an amount equal to the amount of Deferred
         Interest with respect thereto times (x) the aggregate Current Principal
         Amount of such Class or Classes of Senior Certificates over (y) the
         aggregate principal balance of all Mortgage Loans in the related
         Mortgage Loan Group; and

         second, all remaining amounts of Deferred Interest, not allocated to
         the related Class or Classes of Senior Certificates pursuant to
         priority "first" above, to the Classes of Subordinate Certificates, PRO
         RATA, based upon the Current Principal Amount of each such Class, and
         if after the Cross-Over Date, to the Class or Classes of Senior
         Certificates related to the Mortgage Loan Group containing such
         Mortgage Loan (PRO RATA based on Current Principal Amount in the case
         of the Class A-I, Class R-1 and Class R-2 Certificates).

                  (c) On each Distribution Date on which the Current Principal
Amount of a Class of Certificates is increased by Deferred Interest in
accordance with Section 6.02(b) above, the interest payable on such Class shall
be decreased by an equivalent amount.

                  Section 6.03. ALLOCATION OF LOSSES.  (a)  On or prior to each 
Determination Date, the Master Servicer shall determine the amount of any

                  (b) With respect to any Distribution Date, the principal 
portion of each Realized Loss shall be allocated as follows:

                           first, to the Class B-6 Certificates until the 
                  Current Principal Amount thereof has been reduced to zero;

                           second, to the Class B-5 Certificates until the 
                  Current Principal Amount thereof has been reduced to zero;

                           third, to the Class B-4 Certificates until the 
                  Current Principal Amount thereof has been reduced to  zero;

                           fourth, to the Class B-3 Certificates until the 
                  Current Principal Amount thereof has been reduced to zero;

                           fifth, to the Class B-2 Certificates until the 
                  Current Principal Amount thereof has been reduced to zero;

                           sixth, to the Class B-1 Certificates until the 
                  Current Principal Amount thereof has been reduced to zero; and

                           seventh, to the Classes of Senior Certificates, PRO
                  RATA, based upon the respective Current Principal Amounts
                  thereof.

                  (c) Notwithstanding the foregoing, no such allocation of any
Realized Loss shall be made on a Distribution Date to a Class of Certificates to
the extent that such allocation would result in the reduction of the aggregate
Current Principal Amounts of all the Certificates as of such Distribution Date,
after giving effect to all distributions and prior allocations of Realized
Losses on such date, to an amount less than the aggregate Scheduled Principal
Balance of all of the Mortgage Loans as of the first day of the month of such
Distribution Date (such limitation, the "Loss Allocation Limitation").

                  (d) Any Realized Losses allocated to a Class of Certificates
pursuant to Subsection 6.03(b) shall be allocated among the Certificates of such
Class in proportion to their respective Current Principal Amounts. Any
allocation of Realized Losses pursuant to this Subsection 6.03(d) shall be
accomplished by reducing the Current Principal Amount of the related
Certificates on the related Distribution Date in accordance with Subsection
6.03(e).

                  (e) Realized Losses allocated in accordance with this Section
6.03 shall be allocated on the Distribution Date in the month following the
month in which such loss was incurred and, in the case of the principal portion
thereof, after giving effect to distributions made on such
Distribution Date.

                  (f) On each Distribution Date, the Trustee shall determine the
Subordinate Certificate Writedown Amount, if any. Any such Subordinate
Certificate Writedown Amount shall be allocated in reduction of the Current
Principal Amounts of the Classes of the Subordinate


                                      VI-6

<PAGE>



Certificates in the reverse order of their numerical Class designations and from
and after the CrossOver Date, shall be allocated in reduction of the Current
Principal Amounts of the Classes of Senior Certificates, PRO RATA based on their
respective Current Principal Amounts, which reduction shall occur on such
Distribution Date after giving effect to distributions made on such Distribution
Date.

                  (g) Any Net Interest Shortfall will be allocated among the
Classes of Certificates in proportion to the respective amounts of Accrued
Certificate Interest that would have been allocated thereto in the absence of
such Net Interest Shortfall, and any Deferred Interest or the interest portion
of any Realized Loss, for such Distribution Date. The interest portion of
Realized Losses with respect to all Mortgage Loans will be allocated first to
the Subordinate Certificates in reverse order of their numerical designations
commencing with the Class B-6 Certificates and following the Cross-Over Date,
the interest portion of Realized Losses will be allocated PRO RATA to the
Classes of Senior Certificates based on the respective amounts of Accrued
Certificate Interest that would have been allocated thereto in the absence of
any Net Interest Shortfall, Deferred Interest and the interest portion of
Realized Losses. The amount of any interest shortfalls with respect to the
related Mortgage Loan Group that are covered by subordination will constitute
unpaid Accrued Certificate Interest and will be distributable to holders of the
Certificates of the related Classes entitled to such amounts on subsequent
Distribution Dates, to the extent of applicable Group Available Funds after
interest distributions as required herein. Any such amount so carried forward
will not bear interest.

                  (h) With respect to any Distribution Date prior to the
Cross-Over Date, Realized Losses shall be allocated to the REMIC II Regular
Certificates in a manner similar to the allocation of Realized Losses to the

or expense incurred by reason of such Person's willful misfeasance, bad faith or
gross negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder.

                  (d) The Master Servicer shall not be under any obligation to
appear in, prosecute or defend any legal action that is not incidental to its
duties under this Agreement and that in its opinion may involve it in any
expense or liability; PROVIDED, HOWEVER, the Master Servicer may in its
discretion undertake any such action which it may deem necessary or desirable
with respect to this Agreement and the rights and duties of the parties hereto
and the interests of the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Fund, and the Master Servicer shall
be entitled to be reimbursed therefor out of the Certificate Account as provided
by Subsection 4.03(a). Nothing in this Subsection 7.04(d) shall affect the
Master Servicer's obligation to supervise, or to take such actions as are
necessary to ensure, the servicing and administration of the Mortgage Loans
pursuant to Subsection 3.01(a).

                  (e) In taking or recommending any course of action pursuant to
this Agreement, unless specifically required to do so pursuant to this
Agreement, the Master Servicer shall not be required to investigate or make
recommendations concerning potential liabilities which the Trust might incur as
a result of such course of action by reason of the condition of the Mortgaged
Properties but shall give notice to the Trustee if it has notice of such
potential liabilities.

                  Section 7.05. MASTER SERVICER NOT TO RESIGN. Except as
provided in Section 7.06, the Master Servicer shall not resign from the
obligations and duties hereby imposed on it except upon a determination that any
such duties hereunder are no longer permissible under applicable law.
 Any such determination permitting the resignation of the Master Servicer shall
be evidenced by an Opinion of Independent Counsel to such effect delivered to
the Trustee. No such resignation by the Master Servicer shall become effective
until the Trustee or a successor to the Master Servicer reasonably satisfactory
to the Trustee shall have assumed the responsibilities and obligations of the


                                      VII-2

<PAGE>



Master Servicer in accordance with Section 8.02 hereof. The Trustee shall notify
the Rating Agencies of the resignation of the Master Servicer.

                  Section 7.06. SALE AND ASSIGNMENT OF MASTER SERVICING. The
Master Servicer may sell and assign its rights and delegate its duties and
obligations in their entirety as Master Servicer under this Agreement; PROVIDED,
HOWEVER, that: (i) the purchaser or transferee accepting such assignment and
delegation (a) shall be a Person which shall be qualified to service mortgage
loans for FNMA or FHLMC; (b) shall have a net worth of not less than $10,000,000
(unless otherwise approved by each Rating Agency pursuant to clause (ii) below);
(c) shall be reasonably satisfactory to the Trustee (as evidenced in a writing
signed by the Trustee) as having a comparable servicing ability to that of the
Master Servicer on the Closing Date; (d) shall execute and deliver to the
Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement, any custodial agreement
and any agreement substantially in the form of Exhibit G hereto from and after
the effective date of such agreement; (ii) each Rating Agency shall be given
prior written notice of the identity of the proposed successor to the Master
Servicer and each Rating Agency's rating of the Certificates in effect
immediately prior to such assignment, sale and delegation will not be downgraded
or withdrawn as a result of such assignment, sale and delegation, as evidenced
by a letter to such effect delivered to the Master Servicer and the Trustee; and
(iii) the Master Servicer assigning and selling the master servicing shall
deliver to the Trustee an Officer's Certificate and an Opinion of Independent
Counsel, each stating that all conditions precedent to such action under this
Agreement have been completed and such action is permitted by and complies with
the terms of this Agreement. No such assignment or delegation shall affect any
liability of the Master Servicer arising prior to the effective date thereof.

                                     Default

                  Section 8.01. EVENTS OF DEFAULT. "Event of Default," wherever
used herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                           (i) The Master Servicer fails to cause to be
                  deposited in the Certificate Account any amount so required
                  to be deposited pursuant to this Agreement, and such failure
                  continues unremedied for a period of two Business Days after
                  the date such deposit was required to be made; or

                           (ii) The Master Servicer fails to observe or perform
                  in any material respect any other covenants and agreements set
                  forth in the Certificates or this Agreement to be performed by
                  it, which covenants and agreements materially affect the
                  rights of Certificateholders, and such failure continues
                  unremedied for a period of 60 days after the date on which
                  written notice of such failure, properly 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 Fractional Undivided
                  Interests aggregating not less than 25% of the Trust Fund; or

                           (iii) There is entered against the Master Servicer a
                  decree or order by a court or agency or supervisory authority
                  having jurisdiction in the premises for the appointment of a
                  conservator, receiver or liquidator in any insolvency,
                  readjustment of debt, marshaling of assets and liabilities or
                  similar proceedings, or for the winding up or liquidation of
                  its affairs, and the continuance of any such decree or order
                  is unstayed and in effect for a period of 60 consecutive days,
                  or an involuntary case is commenced against the Master
                  Servicer under any applicable insolvency or reorganization
                  statute and the petition is not dismissed within 60 days after
                  the commencement of the case; or

                           (iv) The Master Servicer consents to the appointment
                  of a conservator or receiver or liquidator in any insolvency,
                  readjustment of debt, marshaling of assets and liabilities or
                  similar proceedings of or relating to the Master Servicer or
                  substantially all of its property; or the Master Servicer
                  admits in writing its inability to pay its debts generally as
                  they become due, files a petition to take advantage of any
                  applicable insolvency or reorganization statute, makes an
                  assignment for the benefit of its creditors, or voluntarily
                  suspends payment of its obligations; or

                           (v) The Master Servicer assigns or delegates its
                  duties or rights under this Agreement in contravention of the
                  provisions permitting such assignment or delegation under 
                  Sections 7.05 or 7.06.



                                     VIII-1

<PAGE>



In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the principal of the Trust Fund, by notice in writing to
the Master Servicer (and to the Trustee if given by such Certificateholders),
with a copy to the Rating Agencies, may terminate all of the rights and
obligations (but not the liabilities) of the Master Servicer under this
Agreement and in and to the Mortgage Loans and/or the REO Property serviced by
the Master Servicer and the proceeds thereof. Upon the receipt by the Master
Servicer of the written notice, all authority and power of the Master Servicer
under this Agreement, whether with respect to the Certificates, the Mortgage
Loans, REO Property or under any other related agreements, including the
Sub-Servicing Agreements (but only to the extent that such other agreements
relate to the Mortgage Loans or REO Property) shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the Trustee
pursuant to this Section 8.01; 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 rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; (ii) originals or copies of
all documents of the Master Servicer reasonably requested by the Trustee to
enable it to assume the Master Servicer's duties thereunder; and (iii) the
rights and obligations of the Master Servicer under the Sub-Servicing Agreements
with respect to the Mortgage Loans. In addition to any other amounts which are
then, or, notwithstanding the termination of its activities under this
Agreement, may become payable to the Master Servicer under this Agreement, the
Master Servicer shall be entitled to receive, out of any amount received on
account of a Mortgage Loan or REO Property, that portion of such payments which
it would have received as reimbursement pursuant to Section 3.14 if notice of
termination had not been given. The termination of the rights and obligations of
the Master Servicer shall not affect any obligations incurred by the Master
Servicer prior to such termination.

                  Section 8.02. TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a)
Upon the receipt by the Master Servicer of a notice of termination pursuant to
Section 8.01 or an Opinion of Independent Counsel pursuant to Section 7.05 to
the effect that the Master Servicer is legally unable to act or to delegate its
duties to a Person which is legally able to act, the Trustee shall automatically
become the successor in all respects to the Master Servicer in its capacity
under this Agreement and the transactions set forth or provided for herein and
shall thereafter be subject to all the responsibilities, duties, liabilities and
limitations on liabilities relating thereto placed on the Master Servicer by the
terms and provisions hereof; PROVIDED, HOWEVER, that the Trustee (i) shall be
under no obligation to purchase any Mortgage Loan pursuant to Section 10.01; and
(ii) shall have no obligation whatsoever with respect to any liability incurred
by the Master Servicer at or prior to the time of receipt by the Master Servicer
of such notice or by the Trustee of such Opinion of Independent Counsel. 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
if the Master Servicer had continued to act hereunder, except for those amounts
due the Master Servicer as reimbursement for advances previously made or
expenses previously incurred. Notwithstanding the above, the Trustee may, if


                                     VIII-2

<PAGE>



it shall be unwilling so to act, or shall, if it is legally unable so to act,
appoint or petition a court of competent jurisdiction to appoint, any
established housing and home finance institution which is a FNMA- or
FHLMC-approved servicer, and with respect to a successor to the Master Servicer
only, 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 appointment of a successor to the Master Servicer hereunder, the Trustee
shall act in such capacity as hereinabove provided. In connection with such
appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on the Mortgage Loans as it and
such successor shall agree; PROVIDED, HOWEVER, that no such compensation shall
be in excess of that permitted the Trustee under this Subsection 8.02(a), and
that such successor shall undertake and assume the obligations of the Trustee to
pay compensation to any third Person acting as an agent or independent
contractor in the performance of master servicing responsibilities hereunder.
The Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession.

                  (b) If the Trustee shall succeed to any duties of the Master
Servicer respecting the Mortgage Loans as provided herein, it shall do so in a
separate capacity and not in its capacity as Trustee and, accordingly, the
provisions of Article IX shall be inapplicable to the Trustee in its duties as
the successor to the Master Servicer in the servicing of the Mortgage Loans
(although such provisions shall continue to apply to the Trustee in its capacity
as Trustee); the provisions of Article VII, however, shall apply to it in its
capacity as successor master servicer.

                  Section 8.03. NOTIFICATION TO CERTIFICATEHOLDERS. Upon any
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 and to the Rating
Agencies.

                  Section 8.04. WAIVER OF DEFAULTS. The Trustee shall transmit
by mail to all Certificateholders, within 60 days after the occurrence of any
Event of Default known to the Trustee, unless such Event of Default shall have
been cured, notice of each such Event of Default hereunder known to the Trustee.
The Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 51% of the Trust Fund may, on behalf of all
Certificateholders, waive any default by the Master Servicer in the performance
of its obligations hereunder and the consequences thereof, except a default in
the making of or the causing to be made any required distribution on the
Certificates. Upon any such waiver of a past default, such default shall be
deemed to cease to exist, and any Event of Default arising therefrom shall be
deemed to have been timely remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon except to the extent expressly so waived. The Master Servicer
shall give notice of any such waiver to the Rating Agencies.

                  Section 8.05. LIST OF CERTIFICATEHOLDERS. Upon written request
of three or more Certificateholders of record, for purposes of communicating
with other Certificateholders with respect to their rights under this Agreement,
the Trustee will afford such Certificateholders access during business hours to
the most recent list of Certificateholders held by the Trustee.

                                   ARTICLE IX

                             Concerning the Trustee

                  Section 9.01. DUTIES OF TRUSTEE. (a) The Trustee, prior to the
occurrence of an Event of Default and after the curing or waiver 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 as duties of the
Trustee. If an Event of Default has occurred and 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 their exercise, as a
prudent person would exercise under the circumstances in the conduct of his own
affairs.

                  (b) Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are specifically
required to be furnished to the Trustee pursuant to any provision of this
Agreement, the Trustee 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 resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Master Servicer hereunder.

                  (c) The Trustee shall make monthly distributions and the final
distribution to the Certificateholders as provided in Sections 6.01 and 10.01
herein.

                  (d) 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 or waiver 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, 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;

                           (ii) The Trustee shall not be liable for an error of
                  judgment made in good faith by a Responsible Officer or
                  Responsible Officers of the Trustee, unless it shall be proved
                  that the Trustee was negligent in ascertaining the pertinent
                  facts;

                           (iii) The Trustee shall not be liable with respect to
                  any action taken, suffered or omitted to be taken by it in
                  good faith in accordance with the directions of the Holders of
                  Certificates evidencing Fractional Undivided Interests
                  aggregating not less than 25% of the Trust Fund, if such
                  action or non-action relates to the time, method and place of
                  conducting any proceeding for any remedy available to the


                                      IX-1

<PAGE>



                  Trustee, or exercising any trust or other power conferred
                  upon the Trustee, under this Agreement; and

                           (iv) The Trustee shall not be required to take notice
                  or be deemed to have notice or knowledge of any default or
                  Event of Default unless a Responsible Officer of the Trustee's
                  corporate trust department shall have actual knowledge
                  thereof. In the absence of such notice, the Trustee may
                  conclusively assume there is no such default or Event of
                  Default.

                  The Trustee shall not be required to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of the Master Servicer under this Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

                  (e) All funds received by the Trustee and required to be
deposited in the Certificate Account and the Custody Account pursuant to this
Agreement will be promptly so deposited by the Trustee.

                  Section 9.02. CERTAIN MATTERS AFFECTING THE TRUSTEE. Except as
otherwise provided in Section 9.01:

                           (i) The Trustee may rely and shall be protected in
                  acting or refraining from acting in reliance on any
                  resolution, Officer's Certificate, certificate of a Servicing
                  Officer, certificate of auditors or any other certificate,
                  statement, instrument, opinion, report, notice, request,
                  consent, order, appraisal, 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 with respect to 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 be under no obligation to
                  exercise any of the trusts or powers vested in it by this
                  Agreement, other than its obligation to give notices pursuant
                  to this Agreement, or to institute, conduct or defend any
                  litigation hereunder or in relation hereto at the request,
                  order or direction of any of the Certificateholders pursuant
                  to the provisions of this Agreement, unless such
                  Certificateholders shall have offered to the Trustee
                  reasonable security or indemnity against the costs, expenses
                  and liabilities which may be incurred therein or thereby.
                  Nothing contained herein shall, however, relieve the Trustee
                  of the obligation, upon the occurrence of


                                      IX-2

<PAGE>



                  an Event of Default of which a Responsible Officer of the
                  Trustee's corporate trust department has actual knowledge
                  (which has not been cured), to exercise such of the rights and
                  powers vested in it by this Agreement, and to use the same
                  degree of care and skill in their exercise, as a prudent
                  person would exercise under the circumstances in the conduct
                  of his own affairs;

                           (iv) The Trustee shall not be liable for any action
                  taken, suffered or omitted by it in good faith and believed by
                  it to be authorized or within the discretion or rights or
                  powers conferred upon it by this Agreement;

                           (v) Prior to the occurrence of an Event of Default
                  hereunder and after the curing or waiver 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 Holders of Certificates evidencing Fractional
                  Undivided Interests aggregating not less than 25% of the Trust
                  Fund and provided that 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, reasonably assured to the Trustee by
                  the security afforded to it by the terms of this Agreement.
                  The Trustee may require reasonable indemnity against such
                  expense or liability as a condition to taking any such action.
                  The reasonable expense of every such examination shall be paid
                  by the Certificateholders requesting the investigation;

                           (vi) The Trustee may execute any of the trusts or
                  powers hereunder or perform any duties hereunder either
                  directly or through agents or attorneys; PROVIDED, HOWEVER,
                  that the Trustee may not appoint any agent to perform its
                  custodial or paying agent functions under this Agreement
                  without the express written consent of the Master Servicer,
                  which consent will not be unreasonably withheld. The Trustee
                  shall not be liable or responsible for the misconduct or
                  negligence of any of the Trustee's agents or attorneys or a
                  custodian or paying agent appointed hereunder by the Trustee
                  with due care and, when required, with the consent of the
                  Master Servicer;

                           (vii) Should the Trustee deem the nature of any
                  action required on its part, other than a payment or transfer
                  under Subsection 4.02(b) or Section 4.03, to be unclear, the
                  Trustee may require prior to such action that it be provided
                  by the Master
                  Servicer with reasonable further instructions;

                           (viii) The right of the Trustee to perform any
                  discretionary act enumerated in this Agreement shall not be
                  construed as a duty, and the Trustee shall not be accountable
                  for other than its negligence or willful misconduct in the
                  performance of any such act;

<PAGE>



                           (ix) The Trustee shall not be required to give any
                  bond or surety with respect to the execution of the trust
                  created hereby or the powers granted hereunder; and

                           (x) The Trustee shall have no duty to conduct any
                  affirmative investigation as to the occurrence of any
                  condition requiring the repurchase of any Mortgage Loan by
                  BSMCC pursuant to this Agreement or the eligibility of any
                  Mortgage Loan for purposes of this Agreement.

                  Section 9.03. TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE
LOANS. The recitals contained herein and in the Certificates (other than the
signature and countersignature of the Trustee on the Certificates) shall be
taken as the statements of the Seller, and the Trustee shall have no
responsibility for their correctness. The Trustee makes no representation as to
the validity or sufficiency of the Certificates (other than the signature and
countersignature of the Trustee on the Certificates) or of any Mortgage Loan
except as expressly provided in Sections 2.02 and 2.06 hereof. The Trustee's
signature and countersignature (or countersignature of its agent) on the
Certificates shall be solely in its capacity as Trustee and shall not constitute
the Certificates an obligation of the Trustee in any other capacity. The Trustee
shall not be accountable for the use or application by the Seller of any of the
Certificates or of the proceeds of such Certificates, or for the use or
application of any funds paid to the Seller with respect to the Mortgage Loans.
Subject to the provisions of Section 2.06, the Trustee shall not be responsible
for the legality or validity of this Agreement or any document or instrument
relating to this Agreement, the validity of the execution of this Agreement or
of any supplement hereto or instrument of further assurance, or the validity,
priority, perfection or sufficiency of the security for the Certificates issued
hereunder or intended to be issued hereunder. The Trustee shall at no time have
any responsibility or liability for or with respect to the legality, validity
and enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. The Trustee shall have no responsibility for filing any financing or
continuation statement in any public office at any time or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder or to record this Agreement.

                  Section 9.04. TRUSTEE MAY OWN CERTIFICATES. The Trustee in its
individual capacity or in any capacity other than as Trustee hereunder may
become the owner or pledgee of any Certificates with the same rights it would
have if it were not Trustee, and may otherwise deal with the parties hereto.

                  Section 9.05. TRUSTEE'S FEES AND EXPENSES. The Master Servicer
covenants and agrees to pay to the Trustee the Trustee's Fees with respect to
the calendar month in which the Closing Date occurs. With respect to the
calendar month following the month in which the Closing Date occurs and all
subsequent calendar months, the Trustee's Fees shall be paid from the
Certificate Account, pursuant to Subsection 4.03(b). The Trustee will be
entitled to recover from the Certificate Account pursuant to Subsection 4.03(b)
all reasonable out-of-pocket expenses, disbursements and advances incurred or
made by the Trustee in the administration of the trusts hereunder as set forth
in a fee letter sent by the Trustee to Bear, Stearns & Co. (including the
reasonable compensation,


                                      IX-4

<PAGE>



expenses and disbursements of its counsel) except any such expense, disbursement
or advance as may arise from its negligence or intentional misconduct or which
is the responsibility of the Certificateholders or the Trust Fund hereunder. To
the extent funds in the Certificate Account are insufficient to cover such
expenses, the Trustee may recover such expenses from the Master Servicer. Such
compensation and reimbursement obligation shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust.

                  Section 9.06. ELIGIBILITY REQUIREMENTS FOR TRUSTEE. The
Trustee and any successor Trustee shall during the entire duration of this
Agreement be a state bank or trust company or a national banking association
organized and doing business under the laws of such state or the United States
of America, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus and undivided profits of at least
$40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to
supervision or examination by federal or state authority and, in the case of a
successor Trustee other than pursuant to Section 9.10, rated in one of the two
highest long-term debt categories of, or otherwise acceptable to, each of the
Rating Agencies. The Trustee shall not be an Affiliate of the Master Servicer,
unless the Trustee acts as successor Master Servicer hereunder. If the Trustee
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 9.06 the combined capital and surplus of such
corporation shall be deemed to be its total equity capital (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 9.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 9.08.

                  Section 9.07. INSURANCE. The Trustee, at its own expense,
shall at all times maintain and keep in full force and effect: (i) fidelity
insurance, (ii) theft of documents insurance and (iii) forgery insurance (which
may be collectively satisfied by a "Financial Institution Bond" and/or a
"Bankers' Blanket Bond"). All such insurance shall be in amounts, with standard
coverage and subject to deductibles, as are customary for insurance typically
maintained by banks which act as custodians for investor-owned mortgage pools. A
certificate of an officer of the Trustee as to the Trustee's compliance with
this Section 9.07 shall be furnished to the Master Servicer or any
Certificateholder upon reasonable written request.

                  Section 9.08. RESIGNATION AND REMOVAL OF THE TRUSTEE. (a) The
Trustee may at any time resign and be discharged from the Trust hereby created
by giving written notice thereof to the Master Servicer, with a copy to the
Rating Agencies. Upon receiving such notice of resignation, the Master Servicer
shall promptly appoint a successor Trustee by written instrument, in triplicate,
one copy of which instrument shall be delivered to each of the resigning Trustee
and the successor Trustee. If no successor Trustee shall have been so appointed
and 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.

                  (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 9.06 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 a bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any
public


                                      IX-5

<PAGE>



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 shall be entitled to remove the Trustee and appoint a successor
Trustee by written instrument, in triplicate, one copy of which instrument shall
be delivered to each of the Trustee so removed and the successor Trustee.

                  (c) The Holders of Certificates evidencing Fractional
Undivided Interests aggregating not less than 51% of the 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
each of the Master Servicer, the Trustee so removed and the successor so
appointed.

                  (d) No resignation or removal of the Trustee and appointment
of a successor Trustee pursuant to any of the provisions of this Section 9.08
shall become effective except upon appointment of and acceptance of such
appointment by the successor Trustee as provided in Section
9.09.

                  Section 9.09. SUCCESSOR TRUSTEE. (a) Any successor Trustee
appointed as provided in Section 9.08 shall execute, acknowledge and deliver to
the Master Servicer and to its predecessor Trustee an instrument accepting such
appointment hereunder. The resignation or removal of the predecessor Trustee
shall then 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 Trustee shall after payment
of its outstanding fees and expenses promptly deliver to the successor Trustee
all assets and records of the Trust 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.

                  (b) No successor Trustee shall accept appointment as provided
in this Section 9.09 unless at the time of such acceptance such successor
Trustee shall be eligible under the provisions of Section 9.06.

                  (c) Upon acceptance of appointment by a successor Trustee as
provided in this Section 9.09, the successor Trustee shall mail notice of the
succession of such Trustee hereunder to all Certificateholders at their
addresses as shown in the Certificate Register and to the Rating Agencies. The
Master Servicer shall pay the cost of any mailing by the successor Trustee.

                  Section 9.10. MERGER OR CONSOLIDATION OF TRUSTEE. Any state
bank or trust company or national banking association into which the Trustee may
be merged or converted or with which it may be consolidated or any state bank or
trust company or national banking association resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any state
bank or trust company or national banking association succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder, provided such state bank or trust company or
national banking association shall be eligible under the provisions of Section
9.06. Such succession shall be valid 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 9.11. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
(a) 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 or property constituting the same 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 and the Master Servicer to act as co-trustee or co-trustees, jointly
with the Trustee, or separate trustee or separate trustees, of all or any part
of the Trust, and to vest in such Person or Persons, in such capacity, such
title to the Trust, or any part thereof, and, subject to the other provisions of
this Section 9.11, such powers, duties, obligations, rights and trusts as the
Master Servicer and the Trustee may consider necessary or desirable.

                  (b) If the Master Servicer shall not have joined in such
appointment within 15 days after the receipt by it of a written request so to
do, or in case an Event of Default with respect to the Master Servicer shall
have occurred and be continuing, the Trustee shall have the power to
make such appointment without the Master Servicer.

                  (c) No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor Trustee under Section
9.06 hereunder and no notice to Certificateholders of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 9.08
hereof.

                  (d) In the case of any appointment of a co-trustee or separate
trustee pursuant to this Section 9.11, all rights, powers, duties and
obligations conferred or imposed upon the Trustee and required to be conferred
on such co-trustee shall be conferred or imposed upon and exercised or performed
by the Trustee and such separate trustee or co-trustee jointly, except to the
extent that under any law of any jurisdiction in which any particular act or
acts are to be performed (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 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.

                  (e) Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article IX. 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.

                  (f) To the extent not prohibited by law, any separate trustee
or co-trustee may, at any time, request the Trustee, its agent or
attorney-in-fact, with full power and authority, to do any lawful act under or
with respect to 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,


                                      IX-7

<PAGE>



properties rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor Trustee.

                  (g) No trustee under this Agreement shall be personally liable
by reason of any act or omission of another trustee under this Agreement. The
Master Servicer and the Trustee acting jointly may at any time accept the
resignation of or remove any separate trustee or co-trustee, except that
following the occurrence of any Event of Default which has not been cured, the
Trustee acting alone may accept the resignation of or remove any separate
trustee or co-trustee.

                  Section 9.12. MASTER SERVICER SHALL PROVIDE INFORMATION AS
REASONABLY Required. The Master Servicer shall furnish to the Trustee, during
the term of this Agreement, such periodic, special, or other reports or
information (and in such electronic format) as may reasonably be requested by
the Trustee in order to fulfill its duties and obligations under this Agreement.

                  Section 9.13. FEDERAL INFORMATION RETURNS AND REPORTS TO
CERTIFICATEHOLDERS. (a) For Federal income tax purposes, the taxable year of
each of REMIC I and REMIC II shall be a calendar year and the Trustee shall
maintain or cause the maintenance of the books of each of REMIC I and REMIC II
Assets on the accrual method of accounting.

                  (b) The Trustee shall prepare and file or cause to be filed
with the Internal Revenue Service Federal tax information returns with respect
to each of REMIC I and REMIC II, the Trust Fund, if applicable, and the
Certificates containing such information and at the times and in the manner as
may be required by the Code or applicable Treasury regulations, and shall
furnish to each Holder of Certificates at any time during the calendar year for
which such returns or reports are made such statements or information at the
times and in the manner as may be required thereby. In connection with the
foregoing, the Trustee shall provide the name and address of the person who can
be contacted to obtain information required to be reported to the holders of
regular interests in each of REMIC I and REMIC II (the "REMIC Reporting Agent")
as required by IRS Form 8811. The Trustee shall make the elections to treat each
of REMIC I and REMIC II as a REMIC (which election shall apply to the taxable
period ending December 31, 1998 and each calendar year thereafter) in such
manner as the Code or applicable Treasury regulations may prescribe. The Trustee
shall sign all tax information returns filed pursuant to this Section and any
other returns as may be required by the Code, and in doing so shall rely
entirely upon, and shall have no liability for information provided by, or
calculations provided by, the Seller or the Master Servicer. The Holder of the
Class R-1 Certificate is hereby designated as the "Tax Matters Person" (within
the meaning of Treas. Reg. ss.ss. 1.860F-4(d)) for REMIC I, and the Holder of
the Class R-2 Certificate is hereby designated as "Tax Matters Person" for REMIC
II. The Trustee is hereby designated and appointed as the agent of each such Tax
Matters Person. Any Holder of a Residual Certificate will by acceptance thereof
appoint the Trustee as agent and attorney-in-fact for the purpose of acting as
Tax Matters Person for each of REMIC I and REMIC II during such time as the
Trustee does not own any such Residual Certificate. In the event that the Code
or applicable Treasury regulations prohibit the Trustee from signing tax or
information returns or other statements, or the Trustee from acting as Tax
Matters Person (as an agent or otherwise), the Trustee shall take whatever
action that in its sole good faith judgment is necessary for the proper filing
of such information returns or for the provision of a tax matters person,
including designation of the Holder of a Residual Certificate to


                                      IX-8

<PAGE>



sign such returns or act as tax matters person. Each Holder of a Residual
Certificate shall be bound by this Section.

                  (c) The Trustee shall provide upon request such information
(which shall be provided by the Master Servicer) as required in Section
860D(a)(6)(B) of the Code to the Internal Revenue Service, to any Person
purporting to transfer a Residual Certificate to a Person other than a
transferee permitted by Section 5.05(b), and to any regulated investment
company, real estate investment trust, common trust fund, partnership, trust,
estate, organization described in Section 1381 of the Code, or nominee holding
an interest in a pass-through entity described in Section 860E(e)(6) of the
Code, any record holder of which is not a transferee permitted by Section
5.05(b) (or which is deemed by statute to be an entity with a disqualified
member).

                  (d) The Trustee shall prepare and file or cause to be filed
any state income tax returns required under Applicable State Law with respect to
each of REMIC I and REMIC II or the
Trust Fund.

                                   Termination

                  Section 10.01. TERMINATION UPON REPURCHASE BY THE SELLER OR
ITS DESIGNEE OR LIQUIDATION OF ALL MORTGAGE LOANS. (a) Subject to Section 10.02,
the respective obligations and responsibilities of the Seller, the Master
Servicer and the Trustee created hereby, other than the obligation of the
Trustee or the Master Servicer to make payments to Certificateholders as
hereinafter set forth and to the Trustee, shall terminate upon:

                           (i) the repurchase by or at the direction of the
                  Seller or its designee of all Mortgage Loans and all property 
                  remaining in the Trust at a price equal to (a) 100%
                  of the Outstanding Principal Balance of each Mortgage Loan
                  (other than a Mortgage Loan related to REO Property) as of the
                  date of repurchase, net of the principal portion of any
                  unreimbursed Monthly Advances made by the purchaser, together
                  with interest at the applicable Mortgage Interest Rate accrued
                  but unpaid through and including the last day of the month of
                  repurchase, plus (b) the appraised value of any REO Property
                  (but not more than the Outstanding Principal Balance of the
                  related Mortgage Loan, together with interest at the
                  applicable Mortgage Interest Rate accrued on that balance but
                  unpaid through and including the last day of the month of
                  repurchase), less the good faith estimate of the Seller of
                  liquidation expenses to be incurred in connection with its
                  disposal thereof, such appraisal to be calculated by an
                  appraiser mutually agreed upon by the Seller and the Trustee
                  at the expense of the Seller; or

                           (ii) the later of the making 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 with respect to any
                  Mortgage Loan; PROVIDED, HOWEVER, that in the event that an
                  advance has been made, but not yet recovered, at the time of
                  such termination, the Person having made such advance shall be
                  entitled to receive, notwithstanding such termination, any
                  payments received subsequent thereto with respect to which
                  such advance was made.

                  (b) In no event, however, shall the Trust created hereby
continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United
States to the Court of St. James, living on the date of this Agreement.

                  (c) The right of the Seller or its designee to repurchase all
Mortgage Loans pursuant to Subsection 10.01(a)(i) above shall be exercisable
only if (i) the aggregate unpaid principal balance of such Mortgage Loans at the
time of any such repurchase is less than 5% of the Cut-off Date Balance or (ii)
the Seller based upon an Opinion of Counsel, has determined that the REMIC
status of either REMIC I or REMIC II has been lost or that a substantial risk
exists that such REMIC status will be lost for the then-current taxable year. At
any time thereafter, the Master Servicer may elect to terminate the Trust at any
time, and upon such election, the Master Servicer or its designee shall
repurchase all the Mortgage Loans.

                  (d) The Trustee shall give notice of any termination to the
Certificateholders, with a copy to the Rating Agencies, upon which the
Certificateholders shall surrender their Certificates to the Trustee for payment
of the final distribution and cancellation. Such notice shall be given by
letter, mailed not earlier than the 15th day and not later than the 25th day of
the month next preceding the month of such final distribution, and shall specify
(i) the Distribution Date upon which final payment of the Certificates will be
made upon presentation and surrender of the Certificates at the office of the
Trustee therein designated, (ii) the amount of any such final payment and (iii)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the office of the Trustee therein specified.

                  (e) If the option of the Seller to repurchase or cause the
repurchase of all Mortgage Loans under Subsection 10.01(a)(i) above is
exercised, the Seller and/or its designee, as the case may be, shall deliver to
the Trustee for deposit in the Certificate Account, by the Business Day prior to
the applicable Distribution Date, an amount equal to the repurchase price for
the Mortgage Loans being purchased by it and all property acquired with respect
to such Mortgage Loans remaining in the Trust. Upon the presentation and
surrender of the Certificates, the Trustee shall distribute an amount equal to
(i) the amount otherwise distributable to the Certificateholders (other than the
holder of the Class R-2 Certificate) on such Distribution Date but for such
repurchase, (ii) the Current Principal Amount and any accrued but unpaid
interest at the Pass-Through Rate to the Certificateholders of each Class, and
(iii) the remainder to the Class R-2 Certificateholder. Upon deposit of the
required repurchase price and delivery to the Trustee of an Officer's
Certificate from the Master Servicer certifying that such deposit in the
Certificate Account has been made, and following such final Distribution Date,
the Trustee shall promptly release to the Master Servicer and/or its designee,
as the case may be, the Mortgage Files for the remaining Mortgage Loans, and the
Accounts shall terminate, subject to the Trustee's obligation to hold any
amounts payable to Certificateholders in trust without interest pending final
distributions pursuant to Subsection 10.01(g).

                  (f) In the event that this Agreement is terminated by reason
of the payment or liquidation of all Mortgage Loans or the disposition of all
property acquired with respect to all Mortgage Loans under Subsection
10.01(a)(ii) above, the Master Servicer shall deliver to the Trustee for deposit
in the appropriate subaccount of the Certificate Account all distributable
amounts remaining in the Custody Account and shall cause any Sub-Servicers to
deliver to the Trustee for deposit in the appropriate subaccount of the
Certificate Account all distributable amounts remaining in their Protected
Accounts. Upon the presentation and surrender of the Certificates, the Trustee
shall distribute to the Certificateholders, in accordance with their respective
interests, all distributable amounts remaining in the Certificate Account. Upon
deposit by any Sub-Servicers of such distributable amounts and delivery to the
Trustee of an Officer's Certificate from the Master Servicer certifying that
such deposit has been made, and following such final Distribution Date, the
Trustee shall promptly release to the Master Servicer the Mortgage Files for the
remaining Mortgage Loans, and the Accounts shall terminate, subject to the
Trustee's obligation to hold any amounts payable to the Certificateholders in
trust without interest pending final distributions pursuant to Subsection
10.01(g).

                  (g) If not all of the Certificateholders shall surrender their
Certificates for cancellation within six months after the time specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Trustee may take appropriate steps, or appoint
any agent to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.

                  Section 10.02. ADDITIONAL TERMINATION REQUIREMENTS. (a) If the
option of the Seller to repurchase all the Mortgage Loans under Subsection
10.01(a)(i) above is exercised, the Trust and each of REMIC I and REMIC II shall
be terminated in accordance with the following additional requirements, unless
the Trustee has been furnished with an Opinion of Counsel to the effect that the
failure of the Trust to comply with the requirements of this Section 10.02 will
not (i) result in the imposition of taxes on "prohibited transactions" as
defined in Section 860F of the Code on each of REMIC I and REMIC II or (ii)
cause each of REMIC I and REMIC II to fail to qualify as a REMIC at any time
that any Regular Certificates are outstanding:

                           (i) within 90 days prior to the final Distribution
                  Date, at the written direction of the Master Servicer, the
                  Trustee, as agent for the respective Tax Matters Persons,
                  shall adopt a plan of complete liquidation of the Trust Fund
                  and each of REMIC I and II provided to it by the Master
                  Servicer meeting the requirements of a "Qualified Liquidation"
                  under Section 860F of the Code and any regulations thereunder
                  as prepared by EMC;

                           (ii) at or after the time of adoption of such a plan
                  of complete liquidation and at or prior to the final
                  Distribution Date, the Trustee shall sell for cash all of the
                  assets of the Trust to or at the direction of the Master
                  Servicer; and

                           (iii) at the time of the making of the final payment
                  on the Certificates, the Trustee shall distribute or credit
                  from the Certificate Account (or cause to be distributed or
                  credited) (i) to the Certificateholders, other than the Holder
                  of the Class R-2 Certificate, the Current Principal Amount of
                  the Certificates plus 30 days' interest thereon at the
                  applicable Pass-Through Rate, and (ii) to the Class R-2
                  Certificateholder, all cash on hand from the Certificate
                  Account (other than cash retained to meet claims); and the
                  Trust and each of REMIC I and REMIC II shall terminate at such
                  time.

                  (b) By their acceptance of the Residual Certificates, the
Holders thereof hereby (i) agree to adopt such a plan of complete liquidation
upon the written request of the Master Servicer and to take such action in
connection therewith as may be reasonably requested by the Master Servicer and
(ii) appoint the Master Servicer as their attorney-in-fact, with full power of
substitution, for purposes of adopting such a plan of complete liquidation. The
Trustee shall adopt such plan of liquidation by filing the appropriate statement
on the final tax return of REMIC I and REMIC II.

                            Miscellaneous Provisions

                  Section 11.01. INTENT OF PARTIES. The parties intend that each
of REMIC I and REMIC II shall be treated as a REMIC for federal income tax
purposes and that the provisions of this Agreement should be construed in
furtherance of this intent.

                  Section 11.02. AMENDMENT. (a) This Agreement may be amended
from time to time by the Seller, the Trustee and the Master Servicer, without
notice to or the consent of any of the Certificateholders, to cure any
ambiguity, to correct or supplement any provisions herein that may be defective
or inconsistent with any other provisions herein, to comply with any changes in
the Code or to make any other provisions with respect to matters or questions
arising under this Agreement which shall not be inconsistent with the provisions
of this Agreement; PROVIDED, HOWEVER, that such action shall not, as evidenced
by an Opinion of Independent Counsel, adversely affect in any material respect
the interests of any Certificateholder.

                  (b) This Agreement may also be amended from time to time by
the Seller, the Trustee and the Master Servicer, with the consent of the Holders
of Certificates evidencing Fractional Undivided Interests aggregating not less
than 51% of the Trust Fund or of the applicable Class or Classes if such
amendment affects only such Class or Classes 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 (i) reduce
in any manner the amount of, or delay the timing of, payments received on
Mortgage Loans which are required to be distributed on any Certificate without
the consent of the Holder of such Certificate, (ii) reduce the aforesaid
percentage of Certificates the Holders of which are required to consent to any
such amendment, without the consent of the Holders of all Certificates then
outstanding, or (iii) cause either REMIC I or REMIC II to fail to qualify as a
REMIC for federal income tax purposes, as evidenced by an Opinion of Independent
Counsel which shall be provided to the Trustee other than at the Trustee's
expense.

                  (c) Promptly after the execution of any such amendment, the
Trustee shall furnish a copy of such amendment or written notification of the
substance of such amendment to each Certificateholder, with a copy to the Rating
Agencies.

                  (d) In the case of an amendment under Subsection 11.02(b)
above, it shall not be necessary for the Certificateholders to approve the
particular form of such an amendment. Rather, it shall be sufficient if the
Certificateholders approve the substance of the amendment. 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 11.03. 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
other comparable jurisdictions in which any or all of the Mortgaged Properties
are situated, and in any other appropriate public recording office or elsewhere.
The Master Servicer shall effect such recordation, at its expense upon the
request in writing of a Certificateholder, but


                                      XI-1

<PAGE>



only if such direction is accompanied by an Opinion of Counsel (provided at the
expense of the Certificateholder requesting recordation) to the effect that such
recordation would materially and beneficially affect the interests of the
Certificateholders or is required by law.

                  Section 11.04. LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS. (a)
The death or incapacity of any Certificateholder shall not terminate this
Agreement or the Trust, 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, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

                  (b) Except as expressly provided in this Agreement, no
Certificateholders shall have any right to vote or in any manner otherwise
control the operation and management of the Trust, or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Certificates, be construed so as to establish the Certificateholders from
time to time as partners or members of an association; nor shall any
Certificateholders 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.

                  (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon, under or with respect to this Agreement against the
Seller, the Master Servicer or any successor to any such parties unless (i) such
Certificateholder previously shall have given to the Trustee a written notice of
a continuing default, as herein provided, (ii) the Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 51% of the
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 and expenses and liabilities to be incurred therein or thereby, and (iii)
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.

                  (d) No one or more Certificateholders shall have any right by
virtue of any provision of this Agreement to affect the rights of any other
Certificateholders or to obtain or seek to obtain priority or preference over
any other such Certificateholder, 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 11.04, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

                  Section 11.05. ACTS OF CERTIFICATEHOLDERS. (a) Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Agreement to be given or taken by Certificateholders may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Certificateholders in person or by an agent duly appointed
in writing. Except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee and, where it is expressly required, to the Seller. Proof of execution
of any such instrument or of a writing appointing any such agent shall be


                                      XI-2

<PAGE>



sufficient for any purpose of this Agreement and conclusive in favor of the
Trustee and the Seller, if made in the manner provided in this Section 11.05.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the individual executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

                  (c) The ownership of Certificates (notwithstanding any
notation of ownership or other writing on such Certificates, except an
endorsement in accordance with Section 5.02 made on a Certificate presented in
accordance with Section 5.04) shall be proved by the Certificate Register, and
neither the Trustee, the Seller, the Master Servicer nor any successor to any
such parties shall be affected by any notice to the contrary.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other action of the holder of any Certificate shall bind
every future holder of the same Certificate and the holder of every Certificate
issued upon the registration of transfer or exchange thereof, if applicable, or
in lieu thereof with respect to anything done, omitted or suffered to be done by
the Trustee, the Seller, the Master Servicer or any successor to any such party
in reliance thereon, whether or not notation of such action is made upon such
Certificates.

                  (e) In determining whether the Holders of the requisite
percentage of Certificates evidencing Fractional Undivided Interests have given
any request, demand, authorization, direction, notice, consent or waiver
hereunder, Certificates owned by the Trustee, the Seller, the Master Servicer or
any Sub-Servicer or any Affiliate thereof shall be disregarded, except that, in
determining whether the Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent or waiver, only
Certificates which the Trustee knows to be so owned shall be so disregarded.
Certificates which have been pledged in good faith to the Trustee, the Seller,
the Master Servicer or any Sub-Servicer or any Affiliate thereof may be regarded
as outstanding if the pledgor establishes to the satisfaction of the Trustee the
pledgor's right to act with respect to such Certificates and that the pledgor is
not an Affiliate of the Trustee, the Seller, the Master Servicer or any
Sub-Servicer, as the case may be.

                  Section 11.06. GOVERNING LAW.  THIS AGREEMENT AND THE
CERTIFICATES SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REFERENCE TO ITS CONFLICT OF LAWS RULES AND THE OBLIGATIONS, RIGHTS
AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH
SUCH LAWS.

                  Section 11.07. NOTICES.  All demands and notices hereunder
shall be in writing and shall be deemed given when delivered at or mailed by
registered mail, return receipt requested, postage prepaid, or by recognized
overnight courier, to (i) in the case of the Seller, 245 Park Avenue,

                                  SERIES 1998-6

         evidencing a percentage interest in the distributions allocable to the
         Class [A-___] Certificates with respect to a Trust Fund consisting
         primarily of a pool of conventional one- to four-family adjustable
         interest rate mortgage loans sold by STRUCTURED ASSET MORTGAGE
         INVESTMENTS INC.

                  This Certificate is payable solely from the assets of the
Trust, and does not represent an obligation of or interest in Structured Asset
Mortgage Investments Inc., the Master Servicer, the Trustee referred to below or
Bear Stearns Mortgage Capital Corporation or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by Structured Asset Mortgage
Investments Inc., the Master Servicer, the Trustee or Bear Stearns Mortgage
Capital Corporation or any of their affiliates or any other person. None of the
Company, the Master Servicer, Bear Stearns Mortgage Capital Corporation or any
of their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Fractional Undivided Interest evidenced hereby in the beneficial ownership
interest of Certificates of the same Class as this Certificate in a trust (the
"Trust") generally consisting of thirty year, first lien, adjustable rate
mortgages secured by one- to four- family residences, individual condominium
units, individual cooperative apartments and town houses located primarily in
California, Arizona and Florida (collectively, the "Mortgage Loans") sold by
Structured Asset Mortgage Investments Inc.
("SAMI").
The Mortgage Loans were sold by Bear Stearns Mortgage Capital Corporation to
SAMI. EMC Mortgage Corporation ("EMC") will act as master servicer of the
Mortgage Loans (the "Master


                                        2

<PAGE>



Servicer," which term includes any successors thereto under the Agreement
referred to below). The Trust was created pursuant to the Pooling and Servicing
Agreement dated as of the Cut-off Date specified above (the "Agreement"), by and
among SAMI, as seller, EMC, as Master Servicer, 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,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to a variable
Pass-Through Rate equal to the weighted average of the Net Rates of the Group I
Mortgage Loans. The Trustee will distribute on the 25th day of each month, or,
if such 25th day is not a Business Day, the immediately following Business Day
(each, a "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 Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount
required to be distributed to the Holders of Certificates of the same Class as
this Certificate. The Assumed Final Distribution Date is the first anniversary
of the Distribution Date immediately following the latest scheduled maturity
date of any Mortgage Loan and is not likely to be the date on which the Current
Principal Amount of this Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement and if such
Person holds Certificates with an initial aggregate Current Principal Amount of
not less than $1,000,000, in immediately available funds (by wire transfer or
otherwise) to the account specified in writing by such Person to the Trustee.
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 at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in thirteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust for payment hereunder and that the
Trustee is not liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in
the Agreement, subject to any liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Master Servicer and the rights of the Certificateholders
under the Agreement from time to time by the Master Servicer and the Trustee
with the consent of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% (or in certain cases, Holders of
Certificates of affected Classes evidencing such percentage of the Fractional
Undivided Interests thereof). 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
lieu hereof whether or not notation of such consent is made upon this
Certificate. The 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 Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee in the City of Boston,
Commonwealth of Massachusetts, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates in authorized denominations representing
a like aggregate Fractional Undivided Interest will be issued to the designated
transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Master Servicer, the Trustee and any agent of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and neither the Master Servicer, the Trustee nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust created
thereby (other than the obligations to make payments to Certificateholders with
respect to the termination of the Agreement) shall terminate upon the earlier of
(i) the later of the (A) final payment or other liquidation (or Monthly Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the


                                        4

<PAGE>



Trust in accordance with the terms of the Agreement. Such optional repurchase
may be made only on or after the Distribution Date on which the aggregate unpaid
principal balance of the Mortgage Loans is less than 5% of the aggregate
Scheduled Principal Balance of the Mortgage Loans at the Cut-off Date. The
exercise of such right will effect the early retirement of the Certificates. The
Trust also may be terminated on any Distribution Date upon the determination,
based upon an opinion of counsel, that the REMIC status of REMIC I or REMIC II
has been lost or that a substantial risk exists that such status will be lost
for the then current year. In no event, however, will the Trust created by the
Agreement continue beyond the expiration of 21 years after the death of certain
persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in thirteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust for payment hereunder and that the
Trustee is not liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in
the Agreement, subject to any liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Master Servicer and the rights of the Certificateholders
under the Agreement from time to time by the Master Servicer and the Trustee
with the consent of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% (or in certain cases, Holders of
Certificates of affected Classes evidencing such percentage of the Fractional
Undivided Interests thereof). 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
lieu hereof whether or not notation of such consent is made upon this
Certificate. The 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 Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee in the City of Boston,
Commonwealth of Massachusetts, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates in authorized denominations representing
a like aggregate Fractional Undivided Interest will be issued to the designated
transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Master Servicer, the Trustee and any agent of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and neither the Master Servicer, the Trustee nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust created
thereby (other than the obligations to make payments to Certificateholders with
respect to the termination of the Agreement) shall terminate upon the earlier of
(i) the later of the (A) final payment or other liquidation (or Monthly Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the Trust in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date on which the aggregate unpaid principal balance of the
Mortgage Loans is less than 5% of the aggregate Scheduled Principal Balance of
the Mortgage Loans at the Cut-off Date. The exercise of such right will effect
the early retirement of the Certificates. The

Trust also may be terminated on any Distribution Date upon the determination,
based upon an opinion of counsel, that the REMIC status of REMIC I or REMIC II
has been lost or that a substantial risk exists that such status will be lost
for the then current year. In no event, however, will the Trust created by the
Agreement continue beyond the expiration of 21 years after the death of certain
persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                                  SERIES 1998-6

         evidencing a percentage interest in the distributions allocable to the
         Class [R-___] Certificates with respect to a Trust Fund consisting
         primarily of a pool of conventional one- to four-family adjustable
         interest rate mortgage loans sold by STRUCTURED ASSET MORTGAGE
         INVESTMENTS INC.

                  This Certificate is payable solely from the assets of the
Trust, and does not represent an obligation of or interest in Structured Asset
Mortgage Investments Inc., the Master Servicer, the Trustee referred to below or
Bear Stearns Mortgage Capital Corporation or any of their affiliates or any
other person. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental entity or by Structured Asset Mortgage
Investments Inc., the Master Servicer, the Trustee or Bear Stearns Mortgage
Capital Corporation or any of their affiliates or any other person. None of the
Company, the Master Servicer, Bear Stearns Mortgage Capital Corporation or any
of their affiliates will have any obligation with respect to any certificate or
other obligation secured by or payable from payments on the Certificates.

         This certifies that Bear, Stearns Securities Corp. is the registered
owner of the Fractional Undivided Interest evidenced hereby in the beneficial
ownership interest of Certificates of the same Class as this Certificate in a
trust (the "Trust") generally consisting of thirty year, first lien, adjustable
rate mortgages secured by one- to four- family residences, individual
condominium units, individual cooperative apartments and town houses located
primarily in California, Arizona and Florida (collectively, the "Mortgage
Loans") sold by Structured Asset Mortgage Investments Inc. ("SAMI"). The
Mortgage Loans were sold by Bear Stearns Mortgage Capital Corporation to SAMI.
EMC Mortgage Corporation ("EMC") will act as master servicer of the Mortgage
Loans (the "Master


                                        2

<PAGE>



Servicer," which term includes any successors thereto under the Agreement
referred to below). The Trust was created pursuant to the Pooling and Servicing
Agreement dated as of the Cut-off Date specified above (the "Agreement"), by and
among SAMI, as seller, EMC, as Master Servicer, 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,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to a variable
Pass-Through Rate equal to the weighted average of the Pass Through Rates of all
Classes of Senior Certificates weighted in proportion to the results of
subtracting from the principal balance of each Mortgage Loan Group, the Current
Principal Amount of the related Class or Classes of Senior Certificates. The
Trustee will distribute on the 25th day of each month, or, if such 25th day is
not a Business Day, the immediately following Business Day (each, a
"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 Business Day of the calendar month preceding the month of
such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the first anniversary of the
Distribution Date immediately following the latest scheduled maturity date of
any Mortgage Loan and is not likely to be the date on which the Current
Principal Amount of this Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement and if such
Person holds Certificates with an initial aggregate Current Principal Amount of
not less than $1,000,000, in immediately available funds (by wire transfer or
otherwise) to the account specified in writing by such Person to the Trustee.
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 at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such


                                        3

restrictions, then the Company will have the right, in its sole discretion and
without notice to the Holder of this Certificate, to sell this Certificate to a
purchaser selected by the Company, which purchaser may be the Company, or any
affiliate of the Company, on such terms and conditions
as the Company may choose.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in thirteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust for payment hereunder and that the
Trustee is not liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in
the Agreement, subject to any liability under the Agreement.

                  This Certificate does not purport to summarize the Agreement
and reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Master Servicer and the rights of the Certificateholders
under the Agreement from time to time by the Master Servicer and the Trustee
with the consent of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% (or in certain cases, Holders of
Certificates of affected Classes evidencing such percentage of the Fractional
Undivided Interests thereof). 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
lieu hereof whether or not notation of such consent is made upon this
Certificate. The 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 Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee in the City of Boston,
Commonwealth of Massachusetts, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates in authorized denominations representing
a like aggregate Fractional Undivided Interest will be issued to the designated
transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Master Servicer, the Trustee and any agent of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and neither the Master Servicer, the Trustee nor any
such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust created
thereby (other than the obligations to make payments to Certificateholders with
respect to the termination of the Agreement) shall terminate upon the earlier of
(i) the later of the (A) final payment or other liquidation (or Monthly Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the Trust in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date on which the aggregate unpaid principal balance of the
Mortgage Loans is less than 5% of the aggregate Scheduled Principal Balance of
the Mortgage Loans at the Cut-off Date. The exercise of such right will effect
the early retirement of the Certificates. The Trust also may be terminated on
any Distribution Date upon the determination, based upon an opinion of counsel,
that the REMIC status of REMIC I or REMIC II has been lost or that a substantial
risk exists that such status will be lost for the then current year. In no

COUNTY OF                           )

                  [Name of Officer] being first duly sworn, deposes and says:

                  ARTICLE I That he/she is a [Title of Officer] of [Name of
Investor] (record or beneficial owner of the Mortgage Pass-Through Certificates,
Series 1998-6, Class R-1 and Class R-2 Certificates (the "Class R
Certificates")) (the "Owner"), a corporation duly organized and existing under
the laws of the State of Delaware, on behalf of which he makes this affidavit.

                  2. That the Owner (i) is not and will not be a "disqualified
organization" as of May 29, 1998 within the meaning of Section 860E(e)(5) of the
Internal Revenue Code of 1986, as amended (the "Code"), (ii) will endeavor to
remain other than a disqualified organization for so long as it retains its
ownership in the Class R Certificates, and (iii) is acquiring the Class R
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, 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, 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 Class R Certificates to disqualified organizations under
the Code, that applies to all transfers of Class R 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 middleman) for a
disqualified organization, on the agent; (iii) that the person otherwise 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 Certificates
may be "noneconomic residual interests" within the meaning of Treasury
regulations promulgated pursuant


                                       E-1

<PAGE>



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, unless no significant purpose of the transfer was to impede the
assessment or collection of tax.

                  4. That the Owner is aware of the tax imposed on a
"pass-through entity" holding Class R 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 any Class R Certificates unless the transferee, or the
transferee's 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 Certificates and the provisions of Section 5.02(e) of
the Pooling and Servicing Agreement under which the Class R Certificates were
issued (in particular, clause (iii)(A) and (iii)(B) of Section 5.02(e) 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 5.02(e)). 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 Certificates will only be
owned, directly or indirectly, by an Owner that is not a
disqualified organization.

                  8. The Owner's Taxpayer Identification Number is # ___
- -________.

                  9. This affidavit and agreement relates only to the Class R
Certificates held by the Owner and not to any other holder of the Class R
Certificates. The Owner understands that the liabilities described herein relate
only to the Class R Certificates.

                  10. That no purpose of the Owner relating to the transfer of
any of the Class R Certificates by the Owner is or will be to impede the
assessment or collection of any tax.

                  11. 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. In this regard, the Owner hereby
represents to and for the benefit of the person from whom it acquired the Class
R Certificates that the Owner intends to pay taxes associated with holding such
Class R Certificates as they become due, fully understanding that it may incur
tax liabilities in excess of any cash flows generated by the Class R
Certificates.

trust whose income from sources without the United States is includable in gross

Dear Ladies and Gentlemen:

         In connection with our purchase of Privately Offered Certificates, we
confirm that:

                  (i)      we understand that the Privately Offered Certificates
                           are not being registered under the Securities Act of
                           1933, as amended (the "Act") or any applicable state
                           securities or "Blue Sky" laws, and are being sold to
                           us in a transaction that is exempt from the
                           registration requirements of such laws;

                  (ii)     any information we desired concerning the
                           Certificates, including the Privately Offered
                           Certificates, the trust in which the Certificates
                           represent the entire beneficial ownership interest
                           (the "Trust") or any other matter we deemed relevant

                  (iv)     we are acquiring Privately Offered Certificates for

                           Certificates;

                  (vi)     we agree that in the event that at some future time
                           we wish to dispose of or exchange any of the
                           Privately Offered Certificates (such disposition or

                           directly or through any agent acting on our behalf,

                              (B) if the Privately Offered Certificate is not
                           registered under the Act (as to which we acknowledge

                           Street Bank and Trust Company (the "Trustee") so
                           requests, a satisfactory Opinion of Counsel is
