               purchase similar securities in the secondary mortgage market; and

        (vii)  as of any date of determination, such mortgage pass-through

               of operations of either Assignor or any of their subsidiaries, on
               a consolidated basis, (provided that temporary market conditions,
               as determined by MLMCI in the good faith exercise of its
               reasonable business judgment, shall not in any event render any
               mortgage pass-through security unsalable for purposes hereof).

     (i)  Subject to the terms and conditions stated herein, and relying upon
the representations, warranties and covenants of Assignors herein set forth,
MLMCI agrees to make one or more Loans to each Assignor, which Loans to both
Assignors in the aggregate shall be limited in outstanding principal amount to

<PAGE>
 
shall not be effective until such structuring fee has been received by MLMCI.

     (iii)  Either Assignor may request disbursement of a Loan hereunder by
making a written request, either by mail or facsimile transmission, to MLMCI.
MLMCI shall make such Loan within two (2) days of receipt of such notice, so
long as the terms and conditions of this Agreement are fully satisfied and no
Event of Default hereunder shall have occurred and be continuing.  Any such
disbursement shall be in a minimum amount of $1,000,000 and integral multiples
of $100,000 in excess thereof.

     (iv) Each Loan hereunder shall bear interest at a rate determined pursuant
to a formula set forth in Annex I hereto.  All calculations of interest shall be
made on the basis of a 360-day year and the actual number of days elapsed.

     SECTION 3.  GRANT OF SECURITY INTEREST
                 --------------------------

     (a) Assignors hereby grant, pledge, assign, transfer and deliver to MLMCI
with respect to each Loan on the Closing Date thereof, and grant to MLMCI a lien
upon and security interest in and upon (i) the collateral (the "Collateral")
described in the Confirmation Statement relating to a Loan; (ii) any additional
collateral with respect to such Loan ("Supplemental Collateral") that may be
granted to MLMCI  pursuant to Section 6(c) hereof (provided, however, that any
representations, warranties or covenants contained herein, and the grant of a
security interest with respect to any Supplemental Collateral, shall be
effective as to any Supplemental Collateral (or any proceeds, distributions or
other amounts realized in respect of such Supplemental Collateral) only upon the
delivery of such Supplemental Collateral to MLMCI pursuant to such Section 6(c)
hereof); and (iii) all proceeds, distributions and other amounts realized in
respect of any of the foregoing, as security for the due and punctual payment by
Assignor of the Note and any amounts that may become payable thereunder or
hereunder (the foregoing being herein called the "Obligations").

     (b) Assignors shall, with respect to each Loan, deliver to MLMCI the
Collateral registered in the name of MLMCI or its nominee or, if MLMCI agrees in
its sole discretion, with properly endorsed instruments of transfer (including,
without limitation, any opinions of counsel and certificates required for
transfer) that will enable MLMCI to cause such Collateral to be so registered
without further action on the part of MLMCI other than delivering such
Collateral and such instruments of transfer to the appropriate transfer agent.
The right of MLMCI to receive, and the obligation of Assignors to deliver,
Collateral in the form described in the preceding sentence shall not be waived
or 

                                       6
<PAGE>
 
reduced by MLMCI's having accepted and received, knowingly or unknowingly,
Collateral that has not been so registered or is not accompanied by such
instruments of transfer.

     SECTION 4.  EARNINGS ON COLLATERAL
                 ----------------------

     In the event that the Collateral is registered in the name of MLMCI or an
affiliate, all payments and distributions, whether in cash or in kind, made on
or with respect to the Collateral shall, unless otherwise agreed by MLMCI, be
paid, delivered or transferred directly to MLMCI and, within one (1) Business
Day of receipt thereof, shall, so long as an Event of Default as defined in
Section 10 hereof shall not have occurred and be continuing, be paid to the
related Assignor by wire transfer in immediately available funds.  Following the
occurrence and during the continuation of an Event of Default, if either
Assignor shall receive any payment or distributions on or with respect to the
Collateral, it shall hold such payment or distribution in trust for the benefit
of MLMCI.

     SECTION 5. CONFIRMATION STATEMENT
                ----------------------

     MLMCI shall, with respect to each Loan, deliver a confirmation statement
substantially in the form attached hereto as Exhibit B (in each case, the
"Confirmation Statement") to Assignors confirming the agreement between
Assignors (jointly and severally) and MLMCI as to the specific terms of the
Loan.  Each such Confirmation Statement shall constitute a binding agreement
between Assignors (jointly and severally) and MLMCI as provided below, and this
Agreement is hereby incorporated in each such Confirmation Statement and made a
part thereof as if it were set out in full in each such Confirmation Statement.
Each such Confirmation Statement will be binding upon the parties hereto unless
written notice of objection is given by the objecting party to the other party
within two (2) Business Days after the objecting party's receipt of such
Confirmation Statement.  MLMCI may, but shall not be required to, deliver
Confirmation Statements confirming periodic adjustments in the interest rate for
a particular Loan.

     SECTION 6.  MARGIN DETERMINATIONS
                 ---------------------

     (a) A margin requirement (the "Margin Requirement") expressed as a
percentage with respect to each Eligible Asset for each Loan shall be set forth
in Annex I hereto.  MLMCI shall determine the Market Value for the Collateral in
the good faith exercise of its reasonable business judgment from time to time
and at such time as it may elect in its sole discretion.

                                       7
<PAGE>
 
     (b) MLMCI may, in its sole discretion, from time to time calculate the
current margin (the "Current Margin") with respect to any Loan, which Current
Margin shall equal the amount by which (i) 100% exceeds (ii) a fraction
(expressed as a percentage) (A) the numerator of which is the then outstanding
principal amount of such Loan together with accrued and unpaid interest thereon
to the date of determination and (B) the denominator of which shall be the
Market Value of the related Collateral (including any Supplemental Collateral
delivered pursuant to this Agreement) then held by MLMCI together with accrued
and unpaid interest thereon to the date of determination.

     (c) If MLMCI shall at any time determine with respect to a Loan that the
Current Margin is less than the related Margin Requirement, MLMCI may in its
discretion notify either Assignor of such fact, and Assignors shall be
obligated, jointly and severally, on the date of such notice if such notice is
received prior to 10:00 a.m., New York City time, and on the Business Day next
succeeding the day of such notice if such notice is received after 10:00 a.m.,
New York City time, to, and shall, deliver to MLMCI cash or Supplemental
Collateral acceptable to MLMCI in its reasonable business judgment as Collateral
hereunder, which cash shall be applied to reduce the principal balance of the
related Loan and which Supplemental Collateral shall, in the aggregate, equal an
amount such that, after giving effect to the application of such cash and the
delivery of such Supplemental Collateral, the Current Margin for such Loan will
be at least equal to the related Margin Requirement.  Delivery of Supplemental
Collateral pursuant to this Section 6(c) shall be in such manner as is
acceptable to, and under such additional conditions as may be required by, MLMCI
in its  reasonable business judgment.

     (d) If at any time the Current Margin for a Loan exceeds the Margin
Requirement for such Loan, the related Assignor may, upon notice to MLMCI,
demand that MLMCI redeliver all or any portion of the Supplemental Collateral;
provided, however, that after giving effect to such redelivery, the Current
--------  -------                                                          
Margin for all Loans hereunder would not be less than the Margin Requirement for
all Loans hereunder, and MLMCI shall make good delivery of such Supplemental
Collateral, in a manner equivalent to the manner in which such Supplemental
Collateral was delivered to MLMCI, no later than the Business Day following
receipt by MLMCI of such notice.  In such connection, MLMCI shall execute such
other documents and take such other actions as the related Assignor may
reasonably request in order to evidence and give effect to the release of such
Supplemental Collateral from the security interest granted by this Agreement.
An Assignor may, in the alternative, request that an additional Loan be made
under the terms and conditions hereof in an amount equal to the amount by which
the Current Margin for all Loans hereunder exceeds the 

                                       8
<PAGE>
 
Margin Requirement for all Loans hereunder, which Loan shall be secured by the
Supplemental Collateral.

     (e) With respect to any Eligible Asset that an Assignor has not acquired
directly from MLPF&S or any of its affiliates, such Assignor will either (i)
provide to MLMCI in a timely manner all data with respect thereto that MLMCI may
reasonably request (which, at a minimum, shall include (x) either (A) a CMO
Passport model for the Eligible Asset, if available at such time, or (B) if a
CMO Passport model is not yet available, price/yield tables prepared by the
underwriter or placement agent for the Eligible Asset with the CMO Passport
model to follow within 30 days after the date of issuance of the Eligible Asset,
and (y) a prospectus and, if applicable, a prospectus supplement for the
Eligible Asset) or (ii) such Eligible Asset will be deemed to have a Market
Value of zero.

     SECTION 7.  SUBSTITUTION OF COLLATERAL
                 --------------------------

     MLMCI shall allow the related Assignor, in the sole discretion of Assignors
exercised jointly, to provide Eligible Assets acceptable to MLMCI, in MLMCI's
sole reasonable discretion, to be substituted for existing Collateral of equal
Market Value.  All certificates or instruments representing such substituted
collateral shall be delivered to MLMCI in accordance with Section 3(b) hereof.

     SECTION 8.  REPRESENTATIONS AND WARRANTIES
                 ------------------------------

     Each Assignor hereby represents and warrants to MLMCI, and shall on and as
of the Closing Date of each Loan be deemed to represent and warrant to MLMCI,
that:

          (i)    Due Incorporation.  Assignor has been duly established and is
                 -----------------                                            
validly existing as a corporation in good standing under the laws of the State
of Delaware.

          (ii)   Authorization.  Assignor has full power and authority to
                 -------------
execute and deliver this Agreement and the Note and to perform its obligations
hereunder and thereunder; this Agreement and the Note have each been duly
authorized by all necessary action and neither requires any approval of any
directors or officers or such approval has been obtained, each has been duly
executed and delivered by Assignor and constitutes its legal, valid and binding
obligation, enforceable against it in accordance with its terms, subject, as to
enforcement, to bankruptcy, insolvency, reorganization or similar laws of
general applicability relating to or affecting creditors' rights, to the
assumption that enforcement will be undertaken in a commercially reasonable
manner and to general principles of equity and

                                       9
<PAGE>
 
equitable remedies, regardless of whether enforcement is considered in a
proceeding in equity or at law.

          (iii)  No Conflict.  Neither the execution and delivery nor the
                 -----------                            
performance by Assignor of this Agreement or the Note will conflict with the
governing instruments of Assignor or conflict with, result in a breach of or
constitute a default (which conflict, breach or default could reasonably be
expected to result in any material adverse change in the financial condition or
results of operations of Assignor or could reasonably be expected to materially
and adversely affect the properties or assets thereof, including but not limited
to any of the Collateral) or require any consent (other than has been obtained)
under any instrument or agreement to which Assignor is a party or by which
Assignor may be bound, (which, in the event of a failure to receive such
consent, could reasonably be expected to result in any material adverse change
in the financial condition or results of operations of Assignor or could
reasonably be expected to materially and adversely affect the properties or
assets thereof, including but not limited to the Collateral) or any law, order
or regulation applicable to Assignor of any court, governmental agency,
authority or body having jurisdiction over Assignor and do not and will not
result in or require the creation of any lien, security interest or other charge
or encumbrance (other than pursuant hereto) upon or with respect to any of
Assignor's properties.

          (iv)   Approvals, etc.  Neither the execution and delivery nor the
                 --------------                                             
performance by Assignor of this Agreement requires any authorization, approval,
consent (which, in the event of a failure to receive such consent, could
reasonably be expected to result in any material adverse change in the financial
condition or results of operations of Assignor or could reasonably be expected
to materially and adversely affect the properties or assets thereof, including
but not limited to the Collateral), license, exemption (other than any self-
executing exemption), filing, registration or the taking of any other action in
respect of any federal or state authority (other than has been obtained).

          (v)    Good Title.  Assignor is the owner of the Collateral assigned
                 ----------
to MLMCI by it and such Collateral is free and clear of all liens, charges,
encumbrances and rights of others, except for the security interest created
hereby; and on the related Closing Date, assuming compliance with this Agreement
by MLMCI, MLMCI has a first priority lien on and security interest in the
Collateral (including all proceeds, distributions and other amounts realized in
respect thereof) in favor of MLMCI, subject to no prior lien, charge,
encumbrance or rights of others, and, assuming that MLMCI has taken and
maintains

                                       10
<PAGE>
 
possession of the Collateral either (A) registered in the name of MLMCI or its
nominee or (B) delivered with such instruments of transfer as provided in
Section 3(b) hereof, no further action, including any filing or recordation of
any document, is currently required in order to establish and perfect the liens
on and security interests in the Collateral in favor of MLMCI against any third
parties in any jurisdiction.

          (vi)   Tax Liens.  There are no delinquent federal, state, city,
                 --------- 
county or other taxes relating to an Assignor, the Collateral assigned by it to
MLMCI or any arrangement pursuant to which such Collateral is issued, and all
such tax liabilities have been satisfied except those that are being contested
by such Assignor in good faith and with respect to which payment has been stayed
by a court of competent jurisdiction.

          (vii)  Financial Statements. Since the date of the most recent
                 --------------------                        
financial statement delivered by Assignor to MLMCI, there has been no material
adverse change in Assignor's financial condition or results of operations.

          (viii) Eligible Assets.  All Collateral pledged by
                 ---------------                            
Assignor to MLMCI with respect to any Loan shall qualify as an Eligible Asset.

          (ix)   Corporate Ownership.  No entity owns in excess of ten percent
                 -------------------                                          
(10%) of the capital stock of CWMMHI.

     SECTION 9.  COVENANTS AND AGREEMENTS
                 ------------------------

     Each Assignor hereby covenants and agrees with MLMCI that:

     (a) Taxes.  Assignor will pay and discharge all taxes, levies, liens and
         -----                                                               
other charges on its assets and on the Collateral which, in each case, in any
manner would create any lien or charge upon the Collateral, except those that
are being contested by such Assignor in good faith and with respect to which
payment has been stayed by a court of competent jurisdiction.

     (b) Laws.  Assignor will at all times comply in all material respects with
         ----                                                                  
all laws, ordinances, rules and regulations of any federal, state, municipal or
other public authority having jurisdiction over Assignor or any of its assets
which, in the event of a failure to so comply, could reasonably be expected to
result in any material adverse change in the financial condition or results of
operations of Assignor or could reasonably be expected to materially and
adversely affect the 

                                       11
<PAGE>
 
properties or assets thereof, including but not limited to the Collateral.

     (c) Name and Locations.  Assignor will immediately advise MLMCI in writing
         ------------------                                                    
of the opening of any new chief executive office or the closing of any such
office and of any change in Assignor's name or the places where the books and
records pertaining to the Collateral assigned to MLMCI by Assignor hereunder are
kept.

     (d) Records and Reports.  Assignor will maintain records with respect to
         -------------------                                                 
the Collateral assigned to MLMCI by Assignor hereunder and with respect to the
conduct and operation of its business in conformity with general industry
standards and with no less a degree of prudence than if such Collateral were
held by Assignor for its own account and will furnish MLMCI on request with
reasonable information with respect to such Collateral assigned to MLMCI by
Assignor hereunder and with respect to the conduct and operation of its
business.  In addition, Assignor shall, promptly upon receipt and without any
request from MLMCI, furnish MLMCI with any reports, notices or other
communications from the issuer of, trustee for, or other party relating to, the
Eligible Assets pledged as Collateral hereunder that would ordinarily be sent to
the registered holders of such Eligible Assets.  Assignor will permit MLMCI or
its designated representative to inspect Assignor's records with respect to the
Collateral assigned to MLMCI by Assignor hereunder upon reasonable notice from
MLMCI or its designated representative, at such  reasonable times and as often
as may be reasonably requested, and to make copies or extracts of any and all
thereof.  So long as no Event of Default has occurred and is continuing, such
inspection will be at MLMCI's expense.

     (e) MLMCI's Duty of Care.  Except as herein provided in this Section 9(e),
         --------------------                                                  
Assignor agrees that MLMCI's sole duty with respect to the Collateral shall be
to use reasonable care in the custody, use, operation and preservation of the
Collateral in its possession or control.  MLMCI shall incur no liability to
Assignor for any act of government, act of God, or other destruction in whole or
in part or negligence or wrongful act of custodians or agents selected by and
supervised by MLMCI with reasonable care, or MLMCI's failure to provide adequate
protection or insurance for the Collateral, except to the extent that such
liability has arisen from the gross negligence or willful misconduct of MLMCI.
MLMCI shall have no obligation to take any action to preserve any rights in any
of the Collateral against prior parties, and Assignor hereby agrees to take such
action; Assignor shall defend the Collateral against all such claims and demands
of all persons, at all times, as are adverse to MLMCI.  Nothing stated herein
shall relieve MLMCI of its 

                                       12
<PAGE>
 
obligations to retender the Collateral to the related Assignor in accordance
with the terms of this Agreement.

     (f) Use of Proceeds.  None of the proceeds of any Loan will be used either
         ---------------                                                       
directly or indirectly to acquire any "margin security", as that term is defined
in Regulation G of the Board of Governors of the Federal Reserve System and
Assignor will not take any action which would cause this Agreement or the Note
(and the Loan evidenced hereby and thereby) to violate any regulation of the
Federal Reserve Board.

     (g)  Credit Covenants.
          ---------------- 

     (i)  The ratio of total liabilities to equity of each Assignor and its
     subsidiaries, on a consolidated basis, as determined in accordance with
     GAAP (but excluding (1) limited purpose finance subsidiaries of an Assignor
     that issue collateralized mortgage obligations and (2) trusts that issue
     mortgage pass-through certificates and with respect to which an Assignor
     acts as depositor), shall not at any time exceed 25 to 1; and

     (ii)  The Book Net Worth of CWMMHI and its subsidiaries, on a consolidated
     basis, for any two consecutive calendar quarters shall not be less than or
     equal to 70% of Assignor's Book Net Worth as of the date set forth on the
     first page hereof.

     (h)  Financial Statements.
          -------------------- 

          (i)   As of the date hereof, MLMCI and each Assignor shall provide the
          other with audited fiscal year-end financial statements and additional
          publicly available interim financial statements.  MLMCI and each
          Assignor shall from time to time each provide the other with audited
          year-end financial statements and additional publicly available
          interim financial statements upon such other party's reasonable
          request.

          (ii)  Each Assignor shall provide MLMCI, at the expense of such
          Assignor without request of MLMCI, all financial statements required
          to be filed with the Securities and Exchange Commission in connection
          with an Assignor's 10Q and 10K reports as soon after the filing
          thereof as practicable.

          (iii) Each delivery of the Collateral by each Assignor to MLMCI under
          this Agreement will constitute a representation by such Assignor that
          there has been no material adverse change in such Assignor's financial

                                       13
<PAGE>
 
          condition not disclosed to MLMCI since the date of such Obligor's most
          recent unaudited balance sheet or income statement delivered to MLMCI.
          Each Assignor shall provide MLMCI, from time to time at such
          Assignor's expense, with such information concerning Assignor of a
          financial or operational nature as MLMCI may reasonably request
          promptly upon receipt of such request.

     (i)  Further Covenants.  Without prior written consent of MLMCI, Assignor
          -----------------                                                   
will not:  (1) assign, sell, transfer, pledge or grant any security interest in
any of the Collateral to anyone except MLMCI, permit any financing statement
(except any financing statements in favor of MLMCI) or assignment (except for
any assignments in favor of MLMCI) to be on file in any public office with
respect thereto; (2) permit or suffer to exist any lien, charge, encumbrance or
right of others to attach to any of the Collateral, except as contemplated by
this Agreement; or (3) consent to any amendment or supplement to the documents
pursuant to which the Collateral was issued that would materially and adversely
affect MLMCI's interests hereunder.

     (j)  Joint and Several Liability.  Each Assignor agrees to be jointly and
          ---------------------------                                         
severally liable for the obligations of either Assignor hereunder and all
representations, warranties, covenants and agreements made by or on behalf of
either or both Assignors in this Agreement or in any exhibit hereto or any
document, instrument or certificate delivered pursuant hereto shall be deemed to
have been made by each Assignor, jointly and severally.  The Assignors further
agree that, notwithstanding any right of MLMCI to investigate fully the affairs
of the Assignors and notwithstanding any knowledge of facts determined or
determinable by MLMCI, MLMCI has the right to rely fully on the representations,
warranties, covenants and agreements of either or both Assignors contained in
this Agreement and upon the accuracy of any document, instrument, certificate or
exhibit given or delivered hereunder.  The joint and several obligation of each
Assignor hereunder is absolute, unconditional, irrevocable, present and
continuing and, with respect to any payment to be made to MLMCI, is a guaranty
of payment (and not of collectability) and is in no way conditional or
contingent upon the continued existence of the other Assignor. Any notice or
other communication provided to one Assignor pursuant hereto shall be deemed to
have been given to both Assignors and failure to be sent any notice or
communication contemplated hereby and delivered to the other Assignor shall not
relieve an Assignor from its joint and several liability for the obligations of
the other Assignor hereunder.

     SECTION 10. EVENTS OF DEFAULT
                 -----------------

                                       14
<PAGE>
 
     Each of the following, so long as it shall not have been remedied, shall
constitute an "Event of Default" hereunder:

     (a)  Nonpayment.  Any failure to pay by either Assignor any amounts due
          ----------                                                         
under the Note or any failure to pay by either Assignor any amount due under
this Agreement.

     (b)  Impairment of Interest.  MLMCI shall for any reason cease to have a
          ----------------------                                             
valid, first priority perfected security interest in any of the Eligible Assets;
provided however, that such circumstance shall not constitute an Event of
-------- -------                                                         
Default if after determining the market value of the Eligible Assets without
taking into account the Eligible Assets with respect to which such circumstances
have occurred, no other Event of Default shall have occurred and be continuing.

     (c)  Act of Insolvency.  The filing by either Assignor of a petition in
          -----------------                                                 
bankruptcy, the adjudication of either Assignor as insolvent or bankrupt, the
petition or application by either Assignor for any receiver or trustee for
itself or any substantial part of its property, the commencement by either
Assignor of any proceeding relating to it under any reorganization, arrangement,
dissolution or liquidation law, or the initiation of any such proceeding against
either Assignor if either Assignor indicates by any act its consent thereto or
if such proceeding is not dismissed or stayed within forty-five (45) days (an
"Act of Insolvency").

     (d)  Material Adverse Change.  In the reasonable judgment of MLMCI a
          -----------------------                                        
material adverse change shall have occurred in the business, operations,
properties or financial condition of either Assignor.

     (e)  Default Under Other Contracts and Agreements. Either Assignor shall be
          --------------------------------------------
in default with respect to any normal and customary covenants under any contract
or agreement (including, without limitation, any Repurchase Agreement) to which
it is a party (which covenants include, but are not limited to, an Act of
Insolvency of such Assignor or the failure of such Assignor to make required
payments in an aggregate amount in excess of one million dollars ($1,000,000)
under such contract or agreement as they become due) which default is continuing
and permits acceleration of the obligations of such Assignor under such contract
or agreement by any other party thereto.

     (f)  Merger or Consolidation.  Either Assignor shall merge or consolidate
          -----------------------                                             
into any entity unless the surviving or resulting entity shall be a corporation
organized under the laws of a state of the United States and such entity
expressly assumes by written agreement, executed and delivered to MLMCI in form
and substance 

                                       15
<PAGE>
 
satisfactory to MLMCI, the performance of all of such Obligor's duties and
obligations hereunder.

     (g)  Anticipated Insolvency.  MLMCI shall request assurances as to the
          ----------------------                                           
financial well-being of either Assignor and such assurances shall not have been
provided verbally within twenty-four (24) hours and in writing within forty-
eight (48) hours of such request.

     (h)  Final Judgment.  A final judgment by any competent court in the United
          --------------                                                        
States for the payment of money in an amount of at least $1,000,000 is rendered
against either Assignor, and the same remains undischarged and unpaid for a
period of sixty (60) days during which execution of such judgment is not
effectively stayed.

     (i)  Breach of Representation or Warranty.  Any representation or warranty
          ------------------------------------                                 
made by either Assignor herein or in the Note shall have been incorrect or
untrue when made or repeated or when deemed to have been made or repeated and
such breach is continuing and MLMCI's interests hereunder are materially
adversely affected thereby.

     (j)  Opinion.  A firm of independent accountants shall have failed to issue
          -------                                                               
an opinion or shall have issued an opinion qualified adversely in any material
respect in connection with the most recent audited financial statements of an
Obligor.

     (k)  Breach of Covenant or Agreement.  Either Assignor shall breach any
          -------------------------------                                   
covenant or agreement made by it herein or in the Note and such breach is
continuing and MLMCI's interests hereunder are materially adversely affected
thereby.

     SECTION 11.  REMEDIES
                  --------

     (a)  Action Regarding Collateral.  (i)  If an Event of Default shall occur
          ---------------------------                                          
and be continuing, MLMCI shall exercise reasonable efforts (the reasonableness
of which shall be determined by MLMCI in its discretion in light of the
circumstances) to provide notice to Assignor prior to exercising any remedy in
respect of such Event of Default; provided, however, that notwithstanding
                                  --------  -------                      
anything in this Agreement to the contrary, MLMCI shall not be required, prior
to exercising any remedy in respect of an Event of Default by such Assignor, to
give notice otherwise required hereunder, if MLMCI reasonably believes that (i)
the Collateral then held by MLMCI threatens to decline speedily in value or (ii)
any delay occasioned by the giving of such notice will jeopardize MLMCI's
ability to recover, by sale of such Collateral, all or part of the Obligations
or of any other amounts payable to MLMCI or any affiliate thereof 

                                       16
<PAGE>
 
pursuant hereto. If no prior notice is given, MLMCI shall give notice to the
related Assignor of the remedies effected by MLMCI promptly thereafter. MLMCI
may forthwith apply the cash, if any, then held by it as part of the Collateral
relating to any Loan to the payment of any of the Obligations, and, if there
shall be no such cash or the cash so applied shall not be sufficient to pay in
full all such Obligations, may thereafter collect, receive, appropriate, retain
and realize upon the Collateral, or any part thereof, and may forthwith sell,
assign, contract to sell, or otherwise dispose of and deliver the Collateral, or
any part thereof, in one or more parcels at such public or private sale or
sales, at such place or places, at such price or prices and upon such other
terms and conditions as MLMCI may deem best (provided, however, that MLMCI shall
act in a commercially reasonable manner), for cash or on credit or for future
delivery without assumption of any credit risk, with the right of MLMCI upon any
such sale or sales to purchase all or any part of the Collateral so sold. Upon
any sale, transfer or other disposition of the Collateral pursuant hereto MLMCI
shall have the right to deliver, assign and transfer to the transferee thereof
the Collateral so sold. Each transferee upon any such transfer or other
disposition shall hold the property thereby acquired by it absolutely free from
any claim or right of any kind, including any equity or rights of redemption, of
either Assignor, each of which hereby specifically waives all rights of
redemption, stay or appraisal which it has or may have under any rule of law or
statute whether now existing or hereafter adopted (in the latter case, to the
extent permitted thereby). Each Assignor agrees that MLMCI need give only such
notice of the time and place of any public or private sale (including any
adjourned private sale) or other intended disposition as may be required by
market conditions and standards of commercial reasonableness and that MLMCI need
not in any event give more than five (5) days' notice that such sale or
disposition is to take place. Each Assignor agrees that the notice provided for
in the preceding sentence is reasonable notification of such matters.

     MLMCI shall not be obligated to make any sale pursuant to any such notice.
MLMCI may, without notice or publication, adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the time and
place fixed for the sale, and such sale may be made at any time or place to
which the same may be so adjourned, provided that MLMCI shall act in a
commercially reasonable manner.  In case of any sale of all or any part of the
Collateral on credit or for future delivery, the Collateral so sold may be
retained by MLMCI until the selling price is paid by the purchaser thereof, but
MLMCI shall not incur any liability in case of the failure of such purchaser to
take up and pay for the Collateral so sold and, in case of any such failure,
such Collateral may again be sold upon like 

                                       17
<PAGE>
 
notice MLMCI, however, instead of exercising the power of sale herein conferred
upon it, may proceed by a suit or suits at law or in equity to foreclose the
lien and security interest created hereby and sell the Collateral, or any
portion thereof, under a judgment or decree of a court or courts of competent
jurisdiction.

     (ii)  MLMCI shall have no obligation to realize upon any Collateral, except
through proper application of any distributions with respect to the Collateral
made directly to MLMCI or its agent(s).  Assignor hereby waives the defense of
impairment of the Collateral; provided, however, that MLMCI shall act in a
                              --------  -------                           
commercially reasonable manner.  MLMCI may in its sole discretion elect to
realize upon all or a portion of the Collateral by giving the Assignor credit
for such Collateral, which credit shall be in an amount equal to the Market
Value thereof as of the date of acceleration.

     (b)  Deficiency.  If the proceeds of sale, collection, foreclosure or other
          ----------                                                            
realization of or upon the Collateral are insufficient to cover the costs and
expenses of such realization and the payment in full of the Obligations,
Assignors shall remain jointly and severally liable for any deficiency so long
as MLMCI shall have realized upon the Collateral in a commercially reasonable
manner.

     (c)  Private Sale.  MLMCI shall incur no liability as a result of the sale
          ------------                                                         
of the Collateral (provided, however, that  MLMCI shall act in a commercially
reasonable manner), or any part thereof, at any private sale.  Each Assignor
hereby waives any claims against MLMCI or any holder or holders of the Note
arising by reason of the fact that the price at which the Collateral may have
been sold at such a private sale was less than the price which might have been
obtained at a public sale or was less than the aggregate amount of the
Obligations, even if MLMCI accepts the first offer received and does not offer
the Collateral to more than one offeree (provided, however, that MLMCI shall act
in a commercially reasonable manner).

     (d)  Application of Proceeds. The proceeds of any sale or other realization
          -----------------------
of all or any part of the Collateral, and any other cash at the time held by
MLMCI under this Agreement, shall be applied by MLMCI in the following order of
priority:

          First, to the payment of the reasonable costs and expenses of such
          -----                                                             
     sale and all expenses (including the fees and expenses of counsel),
     liabilities and advances reasonably made or incurred by MLMCI in connection
     therewith.

                                       18
<PAGE>
 
          Second, to the payment of all accrued interest under the Note due or
          ------                                                              
     past due.

          Third, to the payment of principal upon the Note due or past due.
          -----                                                            

          Fourth, to the payment of all other amounts owed by Assignors jointly
          ------                                                               
     and severally under this Agreement.

          Fifth, to the payment of any amounts owed by either Assignor to MLMCI,
          -----                                                                 
     MLPF&S or any affiliate thereof under a Repurchase Agreement.

          Sixth, to the payment of any other amounts owed by either Assignor to
          -----                                                                
     MLMCI or MLPF&S under any other instrument or agreement.

          Seventh, to the payment to the related Assignor, or to such other
          -------                                                          
     person as a court of competent jurisdiction may direct, of any surplus then
     remaining from such proceeds and other cash.

     As used in this Agreement, "proceeds" of the Collateral shall mean cash and
other property received or otherwise realized in respect of the Collateral.

     (e)  Default Rate of Interest.  After any amounts under the Note become due
          ------------------------                                              
and payable and until the balance thereof shall be paid, such amounts shall bear
interest at a per annum rate (based on a year of 360 days and actual days
elapsed) equal to two hundred (200) basis points in excess of the prime rate for
short term bank commercial loans as published in The Wall Street Journal,
                                                 ----------------------- 
changing as such published rate changes, but in no event higher than the maximum
rate permitted by law.

     (f)  Attorney-in-Fact.  Effective upon the occurrence and during the
          ----------------                                               
continuation of an Event of Default hereunder, MLMCI is hereby appointed the
attorney-in-fact of each Assignor for the purpose of carrying out the provisions
of this Agreement and taking any action and executing any instruments which
MLMCI may deem necessary or advisable to accomplish the purposes hereof, which
appointment as attorney-in-fact is irrevocable and coupled with an interest.
Without limiting the generality of the foregoing, after an Event of Default has
occurred and is continuing, MLMCI shall have the right and power to receive,
endorse and collect all checks made payable to the order of an Assignor
representing any distribution in respect of any of the Collateral or any part
thereof and to give full discharge for the same.

                                       19
<PAGE>
 
     (g)  Payments on Collateral to an Assignor.
          ------------------------------------- 

               (i) Following the occurrence and during the continuation of an
     Event of Default hereunder, all rights of the related Assignor to receive
     any payments from the related Collateral which it would otherwise be
     authorized to receive shall cease, and all such rights shall thereupon
     become vested in MLMCI, which shall thereupon have the sole right to
     receive and hold as Collateral such payments.

               (ii) Following the occurrence and during the continuation of an
     Event of Default hereunder, all payments which are received by either
     Assignor contrary to the provisions of the preceding subsection (i) shall
     be received in trust for the benefit of MLMCI, shall be segregated from
     other funds of both Assignors and shall be promptly paid to MLMCI.

     SECTION 12.  EFFECTS OF APPLICABLE LAW
                  -------------------------

     (a) In the event that any Applicable Law with respect to a Non-Widely
Traded Security or any Change of Applicable Law with respect to a Widely Traded
Security results in any material restriction or limitation on the corporate
power or authority of MLMCI to enter into a proposed Loan or to continue to
maintain an existing Loan with respect to any Collateral that would otherwise
qualify as an Eligible Asset, (A) the parties hereto shall in good faith
negotiate such additional or revised terms to this Agreement as will result in a
permissible transaction that corresponds to the economic equivalent of the
arrangement originally contemplated by the parties hereunder or (B) if such
Applicable Law or Change of Applicable Law, as the case may be, does not permit
such renegotiation, the commitment of MLMCI to enter into or to continue to
maintain the Loan with respect to such Eligible Asset shall be cancelled or
modified (depending upon the stated effect of the Applicable Law or Change of
Applicable Law, as appropriate), with such cancellation and/or modification to
be operative upon the earlier of (x) the date required by such Applicable Law or
Change of Applicable Law, as appropriate, or (y) the date on which Assignor has
secured alternative financing for the affected Eligible Asset.

     (b) In the event that any Applicable Law with respect to a Non-Widely
Traded Security or any Change of Applicable Law with respect to a Widely Traded
Security results in any adverse economic effect on MLMCI that is material with
respect to the particular Loan, the parties hereto shall in good faith negotiate
such additional or revised terms related to pricing that will 

                                       20
<PAGE>
 
result in a Loan that corresponds to the economic equivalent of the arrangement
originally contemplated by MLMCI and Assignors.

     SECTION 13.  INTEREST PAYMENTS; REPAYMENT OF PRINCIPAL
                  -----------------------------------------

     (a) Interest on each Loan shall be payable on the date described in Annex I
hereto.

     (b) The principal portion of each Loan shall be due and payable not later
than the termination date referred to in Section 14(g) hereof and may be repaid
in whole or in part at the discretion of the related Assignor on any date on
which a payment of interest is to be made thereon by an Assignor pursuant to the
terms of this Agreement provided that (i) such Assignor shall have provided
MLMCI with not less than two (2) Business Days' written notice of such
Assignor's intention to effect such repayment and the amount thereof, (ii) all
payments of interest then due and owing on the Loan are paid in full and (iii)
no Event of Default has occurred and is continuing with respect to any of
Assignors' Obligations hereunder or under the Note.

     (a) No Waiver.  No waiver or amendment of or forbearance in enforcing any
         ---------

         ----------------                                                       
on the Collateral and the proceeds of the sale thereof pursuant to this
Agreement against any amounts owed by either Assignor (or any subsidiary
thereof) to MLMCI, MLPF&S or any affiliate thereof under any other instrument or
agreement (including, without limitation, any Repurchase Agreement).  The right
of set-off provided for herein shall not diminish any other rights (whether of
set-off, contribution or otherwise) that MLMCI and its affiliates may have with
respect to the Collateral and the distributions thereon and the proceeds
thereof.

     (c) Governing Law; Severability.  This Agreement shall be governed by and
         ---------------------------                                          
construed in accordance with the laws of the State of New York applicable to
agreements made and entirely performed therein.  Unless otherwise defined
herein, terms defined in the Uniform Commercial Code in the State of New York
are used herein as defined therein.  Each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement shall be prohibited by or be invalid
under such law, such provision shall be ineffective to the extent of such

                                       21
<PAGE>
 
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement.

     (d) Construction.  The captions in this Agreement are for convenience of
         ------------                                                        
reference only and shall not affect the construction or interpretation of any of
the provisions hereof.

     (e) Assignment; Right to Transfer. (i) This Agreement shall be binding upon
         -----------------------------                                          
and shall inure to the benefit of each of the parties hereto and their
respective successors and assigns; provided, however, that neither this
                                   --------  -------                   
Agreement nor any rights or other obligations hereunder or under the Note may be
assigned by either Assignor without prior written consent of MLMCI and any
attempted or purported assignment hereof or thereof shall be void.  MLMCI may
assign, pledge, sell or hypothecate any or all of its rights hereunder and under
the Note without the consent of any party, provided however, that the Assignor
                                           -------- -------                   
shall not be required to recognize any holder of the Note other than MLMCI or
its affiliates.  (ii) Nothing in this Agreement shall preclude MLMCI from
engaging in transactions with third parties involving the selling pursuant to a
repurchase arrangement, pledging, hypothecating or other transfer of the
Collateral but no such transaction shall relieve MLMCI of its obligations
hereunder.

     (f) Notices, Payments, Deliveries.  Unless otherwise provided herein, all

     (g)  Termination.
          ----------- 

               (i) This Agreement and MLMCI's obligation to make Loans hereunder
     pursuant to the terms hereof shall terminate automatically without any
     requirement for notice, and all outstanding Obligations of both Assignors
     that have not yet become due and payable will be due and payable
     automatically without any requirement for notice, upon the earlier of (i)
     two years after the date set forth on the first page hereof and (ii) the
     written agreement of both Assignors and MLMCI; provided, however, that
                                                    --------  -------      
     notwithstanding the foregoing, this Agreement shall continue in full force
     and effect until all Obligations of both Assignors hereunder have been paid
     in full.  Upon termination of this Agreement and satisfaction of all of
     Assignors' Obligations hereunder, MLMCI shall release its lien and security
     interest hereunder and assign, transfer and deliver, against receipt, any
     remaining Collateral and money received in respect thereof to or on the
     order of the related Assignor.  Upon the request of the related Assignor,
     MLMCI will then execute termination statements and such other documents as
     such Assignor may reasonably request as are necessary to make clear upon
     the public record the termination of the lien and security interests
     created hereby with respect to the Collateral.

               (ii) If, at any time prior to the date seventeen (17) months
     after the date of this Agreement, Assignors request that MLMCI renew this
     Agreement for an additional term of mutually acceptable duration, MLMCI
     will notify Assignors not later than the date eighteen (18) months after
     the date of this Agreement if it will so renew this Agreement; provided,
                                                                    -------- 
     however, that (x) no such agreement to renew the term of this Agreement
     -------                                                                
     shall preclude MLMCI from thereafter declining to make Loans hereunder
     either (A) pursuant to any provision set forth herein or (B) if there is a
     material adverse change in the financial condition or results of operations
     of either Assignor or any of its subsidiaries, on a consolidated basis, and
     (y) the foregoing shall not preclude Assignors from requesting the renewal
     of the term of this Agreement at any other time.

          (i) For so long as no Event of Default shall have occurred and shall
          be continuing, each party shall bear its own expenses in connection
          with the Loans contemplated hereby and any amendments, extension or
          modifications hereof.

          (ii) Following the occurrence of an Event of Default that either (A)
          is continuing or (B) with respect to which MLMCI is exercising its
          remedies hereunder, Assignors agree, jointly and severally, to pay to
          MLMCI on demand all reasonable costs and expenses (including
          reasonable expenses for legal services of every kind) of any
          subsequent enforcement of any of the provisions hereof, or of the
          performance by MLMCI of any Obligations of either Assignor in respect
          of the Collateral which Assignor has failed or refused to perform, or
          any actual or attempted sale, or any exchange, enforcement,
          collection, compromise or settlement in respect of any of the
          Collateral and for the custody, care or preservation of the Collateral
          (including reasonable insurance costs) and defending or asserting
          rights and claims of MLMCI in respect thereof, by litigation or
          otherwise, including reasonable expenses of insurance.  In addition,
          Assignors agree, jointly and severally, to pay to MLMCI on demand all
          reasonable costs and expenses (including reasonable expenses for legal
          services) of the registration of the Collateral in the name of MLMCI
          or its nominee.  All such expenses shall be Obligations to MLMCI
          secured under this Agreement.


     (i) Indemnification.  Assignors agree, jointly and severally, to indemnify
         ---------------                                                       
and hold harmless MLMCI against all liabilities and expenses to which MLMCI may
become subject relating to any fees, taxes or liability to any third party
resulting from any action taken or omitted by or upon instructions of either
Assignor with respect to the Collateral.

     (j)  Confidentiality.  Each of the parties hereto acknowledges that the
          ---------------                                                   
Agreement is confidential in nature and each such party agrees that, unless
otherwise directed by a court of regulatory entity of competent jurisdiction or
as may be required by federal or state law (which determination as to federal or
state law shall be based upon written advice of counsel), it shall limit the
distribution of such document to its officers, employees, attorneys, accountants
and agents as required in order to conduct its business with the other parties
hereto.  This subparagraph (i) shall not apply to information

                                       25
<PAGE>
 
which has otherwise lawfully entered the public domain or which the other
parties have given written permission to disclose.

     (k) Further Assurances.  Each Assignor agrees that, from time to time upon
         ------------------                                                    
the prior written request of MLMCI, it will (i) execute and deliver such further
documents and do such other acts and things as MLMCI may reasonably request in
order to fully effectuate the purposes of this Agreement (including, without
limitation, the delivery of appropriate transfer documentation as contemplated
by Section 3(b) hereof) and (ii) provide such opinions of counsel concerning
matters relating to this Agreement as MLMCI may reasonably request.

     (l) Remedies Cumulative.  All rights, remedies and powers of MLMCI
         -------------------

alternative or exclusive, and shall be in addition to all other rights, remedies
and powers of MLMCI whether under law, equity or agreement.  In addition to the
rights and remedies granted to it in this Agreement or under the Note, MLMCI
shall have all the rights and remedies of a secured party under the Uniform
Commercial Code.

     (m) Consent to Jurisdiction.  Notwithstanding any termination of this
         -----------------------                                          
Agreement, each Assignor hereby agrees that any legal action or proceeding
against either Assignor in connection with this Agreement may be brought in the
courts of the State of New York or of the United States of America located in
the City and State of New York, Borough of Manhattan, as MLMCI may elect, and
each Assignor hereby irrevocably submits to the non-exclusive jurisdiction of
each of said courts, and waives any objection on the grounds of venue, forum non
conveniens or similar ground.

     (n) Counterparts.  This Agreement may be executed in any number of
         ------------                                                  
counterparts, each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument.
 
     (o) Superseding of Prior Agreements.  This Agreement shall supersede the
         -------------------------------                                     
Master Assignment Agreement, dated as of July 26, 1994, among the parties

3.   INITIATION; CONFIRMATION; TERMINATION

     (a) An agreement to enter into a Transaction may be made orally or in

the Transaction, the Purchased Securities shall be transferred to Buyer or its
agent against the transfer of the Purchase Price to an account of Seller.

     (b) Upon agreeing to enter into a Transaction hereunder, Buyer or Seller
(or both), as shall be agreed, shall promptly deliver to the other party a
written confirmation of each Transaction (a "Confirmation"). The Confirmation
shall describe the Purchased Securities (including CUSIP number, if any),
identify Buyer and Seller and set forth (i) the Purchase Date, (ii) the Purchase
Price, (iii) the Repurchase Date, unless the Transaction is to be terminable on
demand, (iv) the Pricing Rate or Repurchase Price applicable to the Transaction,
and (v) any additional terms or conditions of the Transaction not inconsistent

constitute conclusive evidence of the terms agreed between Buyer and Seller with
respect to the Transaction to which the Confirmation relates, unless with
respect to the Confirmation specific objection is made promptly after receipt
thereof. In the event of any conflict between the terms of such Confirmation and
this Agreement, this Agreement shall prevail.

     (c) In the case of Transactions terminable upon demand, such demand shall
be made by Buyer or Seller, no later than such time as is customary in
accordance with market practice, by telephone or otherwise on or prior to the
business day on which such termination will be effective. On the date specified
in such demand, or on the date fixed for termination in the case of Transactions
having a fixed term, termination of the Transaction will be effected by transfer
to Seller or its agent of the Purchased Securities and any Income in respect
thereof received by Buyer (and not previously credited or transferred to, or
applied to the obligations of, Seller pursuant to Paragraph 5 hereof) against
the transfer of the Repurchase Price to an account of Buyer.

4.   MARGIN MAINTENANCE

     (a) If at any time the aggregate Market Value of all Purchased Securities
subject to all Transactions in which a particular party hereto is acting as
Buyer is less than the aggregate Buyer's Margin Amount for all such Transactions
(a "Margin Deficit"), then Buyer may by notice to Seller require Seller in such
Transactions, at Seller's option, to transfer to Buyer cash or additional
Securities reasonably acceptable to Buyer ("Additional Purchased Securities"),
so that the cash and aggregate Market Value of the Purchased Securities,
including any such Additional Purchased Securities, will thereupon equal or
exceed such aggregate Buyer's Margin Amount (decreased by the amount of any
Margin Deficit as of such date arising from any Transactions in which such Buyer
is acting as Seller).

     (b) If at any time the aggregate Market Value of all Purchased Securities
subject to all Transactions in which a particular party hereto is acting as
Seller exceeds the aggregate Seller's Margin Amount for all such Transactions at
such time (a "Margin Excess"), then Seller may by notice to Buyer require Buyer
in such Transactions, at Buyer's option, to transfer cash or Purchased
Securities to Seller, so that the aggregate Market Value of the Purchased
Securities, after deduction of any such cash or any Purchased Securities so
transferred, will thereupon not exceed such aggregate Seller's Margin Amount
(increased by the amount of any Margin Excess as of such date arising from any
Transactions in which such Seller is acting as Buyer).

     (c) Any cash transferred pursuant to this Paragraph shall be attributed to
such Transactions as shall be agreed upon by Buyer and Seller.

                                       35
<PAGE>
 
     (d) Seller and Buyer may agree, with respect to any or all Transactions
hereunder, that the respective rights of Buyer or Seller (or both) under
subparagraphs (a) and (b) of this Paragraph may be exercised only where a Margin
Deficit or Margin Excess exceeds a specified dollar amount or a specified
percentage of the Repurchase Prices for such Transactions (which amount or
percentage shall be agreed to by Buyer and Seller prior to entering into any
such Transactions).

     (e) Seller and Buyer may agree, with respect to any or all Transactions
hereunder, that the respective rights of Buyer and Seller under subparagraphs
(a) and (b) of this Paragraph to require the elimination of a Margin Deficit or
a Margin Excess, as the case may be, may be exercised whenever such a Margin
Deficit or Margin Excess exists with respect to any single Transaction hereunder
(calculated without regard to any other Transaction outstanding under this
Agreement).

5.   INCOME PAYMENTS

     Where a particular Transaction's term extends over an income payment date
on the Securities subject to that Transaction, Buyer shall, as the parties may
agree with respect to such Transaction (or, in the absence of any agreement, as
Buyer shall reasonably determine in its discretion), on the date such income is
payable either (i) transfer to or credit to the account of Seller an amount
equal to such income payment or payments with respect to any Purchased
Securities subject to such Transaction or (ii) apply the income payment or
payments to reduce the amount to be transferred to Buyer by Seller upon
termination of the Transaction. Buyer shall not be obligated to take an action
pursuant to the preceding sentence to the extent that such action would result
in the creation of a Margin Deficit, unless prior thereto or simultaneously
therewith Seller transfers to Buyer cash or Additional Purchased Securities
sufficient to eliminate such Margin Deficit.

6.   SECURITY INTEREST

     Although the parties intend that all Transactions hereunder be sales and
purchases and not loans, in the event any such Transactions are deemed to be
loans, Seller shall be deemed to have pledged to Buyer as security for the
performance by Seller of its obligations under each such Transaction, and shall
be deemed to have granted to Buyer a security interest in, all of the Purchased
Securities with respect to all Transactions hereunder and all proceeds thereof.

7.   PAYMENT AND TRANSFER

     Unless otherwise mutually agreed, all transfers of funds hereunder shall be
in immediately available funds. All Securities transferred by one party hereto
to the other party (i) shall be in suitable form for transfer or shall be
accompanied by duly executed instruments of transfer or assignment in blank and
such other documentation as the party receiving possession may reasonably
request, (ii) shall be transferred on the book-entry system of a Federal Reserve
Bank, or (iii) shall be transferred by any other method mutually acceptable to
Seller and Buyer. As used herein with respect to Securities, "transfer" is
intended to have the same meaning as when used in Section 8-313 of the New York
Uniform Commercial Code or, where applicable, in any federal regulation
governing transfers of the Securities.

8.   SEGREGATION OF PURCHASED SECURITIES

     To the extent required by applicable law, all Purchased Securities in the
possession of Seller shall be segregated from other securities in its possession
and shall be identified as subject to this Agreement.  Segregation may be
accomplished by appropriate identification on the books and records of the
holder, including a financial intermediary or a clearing corporation.  Title to
all Purchased Securities shall pass to Buyer and, unless otherwise agreed by
Buyer and Seller, nothing in this Agreement shall preclude Buyer from engaging
in repurchased transactions with the Purchased Securities or otherwise pledging
or hypothecating the Purchased Securities, but no such transaction shall relieve
Buyer of its obligations to transfer Purchased Securities to Seller pursuant to
Paragraphs 3, 4 or 11 hereof, or of Buyer's obligation to credit or pay Income
to, or apply Income to the obligations of, Seller pursuant to Paragraph 5
hereof.

     REQUIRED DISCLOSURE FOR TRANSACTIONS IN WHICH THE SELLER RETAINS CUSTODY
     OF THE PURCHASED SECURITIES

       Seller is not permitted to substitute other securities for those subject
to this Agreement and therefore must keep Buyer's securities segregated at all
times, unless in this Agreement Buyer grants Seller the right to substitute
other securities. If Buyer grants the right to substitute, this means that
Buyer's securities will likely be commingled with Seller's own securities during
the trading day. Buyer is advised that, during any trading day that Buyer's
securities are commingled with Seller's securities, they (will)* (may)** be
subject to liens granted by Seller to (its clearing bank)* (third parties)** and
may be used by Seller for deliveries on other securities transactions. Whenever
the securities are commingled, Seller's ability to resegregate substitute
securities for Buyer will be subject to Seller's ability to satisfy (the
clearing)* (any)** lien or to obtain substitute securities.

 *Language to be used under 17 C.F.R. 403.4(e) if Seller is a government
  securities broker or dealer other than a financial institution.
**Language to be used under 17 C.F.R. 403.5(d) if Seller is a financial
  institution.

<PAGE>
 
9.   SUBSTITUTION

     (a) Seller may, subject to agreement with and acceptance by Buyer,
substitute other Securities for any Purchased Securities. Such substitution
shall be made by transfer to Buyer of such other Securities and transfer to
Seller of such Purchased Securities. After substitution, the substituted
Securities shall be deemed to be Purchased Securities.

     (b)  In Transactions in which the Seller retains custody of Purchased
Securities, the parties expressly agree that Buyer shall be deemed, for purposes
of subparagraph (a) of this Paragraph, to have agreed to and accepted in this
Agreement substitution by Seller of other Securities for Purchased Securities;
provided, however, that such other Securities shall have a Market Value at least
equal to the Market Value of the Purchased Securities for which they are
substituted.

obligations hereunder (each an "Event of Default"):

     (a) At the option of the non defaulting party, exercised by written notice
to the defaulting party (which option shall be deemed to have been exercised,
even if no notice is given, immediately upon the occurrence of an Act of
Insolvency), the Repurchase Date for each Transaction hereunder shall be deemed

Prices for all such Transactions, the defaulting party's right, title and
interest in all Purchased Securities subject to such Transactions shall be
deemed transferred to the nondefaulting party, and the defaulting party shall
deliver all such Purchased Securities to the nondefaulting party.

     (d) After one business day's notice to the defaulting party (which notice
need not be given if an Act of Insolvency shall have occurred, and which may be
the notice given under subparagraph (a) of this Paragraph or the notice referred
to in clause (ii) of the first sentence of this Paragraph), the nondefaulting
party may:

         (i) as to Transactions in which the defaulting party is acting as
     Seller, (A) immediately sell, in a recognized market at such price or
     prices as the nondefaulting party may reasonably deem satisfactory, any or
     all Purchased Securities subject to such Transactions and apply the
     proceeds thereof to the aggregate unpaid Repurchase Prices and any other
     amounts owing by the defaulting party hereunder or (B) in its sole
     discretion elect, in lieu of selling all or a portion of such Purchased

<PAGE>
 
     credit for such Purchased Securities in an amount equal to the price
     therefor on such date, obtained from a generally recognized source or the
     most recent closing bid quotation from such a source, against the aggregate
     unpaid Repurchase Prices and any other amounts owing by the defaulting
     party hereunder; and

         (ii) as to Transactions in which the defaulting party is acting as

     defaulting party to the nondefaulting party as required hereunder or (B) in
     its sole discretion elect, in lieu of purchasing Replacement Securities, to
     be deemed to have purchased Replacement Securities at the price therefor on
     such date, obtained from a generally recognized source or the most recent
     closing bid quotation from such a source.

     (e) As to Transactions in which the defaulting party is acting as Buyer,
the defaulting party shall be liable to the nondefaulting party (i) with respect

Replacement Securities therefor over the Repurchase Price for such Purchased
Securities and (ii) with respect to Additional Purchased Securities, for the

Transaction hereunder in respect of which the defaulting party is acting as
Buyer shall not increase above the amount of such Repurchase Price for such
Transaction determined as of the date of the exercise or deemed exercise by the
nondefaulting party of its option under subparagraph (a) of this Paragraph.

     (g) The defaulting party shall be liable to the nondefaulting party for the
amount of all reasonable legal or other expenses incurred by the nondefaulting
party in connection with or as a consequence of an Event of Default, together
with interest thereon at a rate equal to the greater of the Pricing Rate for the
relevant Transaction or the Prime Rate.

     (h) The nondefaulting party shall have, in addition to its rights
hereunder, any rights otherwise available to it under any other agreement or
applicable law.

12.  SINGLE AGREEMENT

     Buyer and Seller acknowledge that, and have entered hereinto and will enter
into each Transaction hereunder in consideration of and in reliance upon the
fact that, all Transactions hereunder constitute a single business and
contractual relationship and have been made in consideration of each other.
Accordingly, each of Buyer and Seller agrees (i) to perform all of its
obligations in respect of each Transaction hereunder, and that a default in the
performance of any such obligations shall constitute a default by it in respect
of all Transactions hereunder, (ii) that each of them shall be entitled to set
off claims and apply property held by them in respect of any Transaction against
obligations owing to them in respect of any other Transactions hereunder and
(iii) that payments, deliveries and other transfers made by either of them in
respect of any Transaction shall be deemed to have been made in consideration of
payments, deliveries and other transfers in respect of any other Transactions
hereunder, and the obligations to make any such payments, deliveries and other
transfers may be applied against each other and netted.

13.  NOTICES AND OTHER COMMUNICATIONS

     Unless another address is specified in writing by the respective party to
whom any notice or other communication is to be given hereunder, all such
notices or communications shall be in writing or confirmed in writing and
delivered at the respective addresses set forth in Annex II attached hereto.

14.  ENTIRE AGREEMENT; SEVERABILITY

     This Agreement shall supersede any existing agreements between the parties
containing general terms and conditions for repurchase transactions.  Each
provision and agreement herein shall be treated as separate and independent from
any other provision or agreement herein and shall be enforceable notwithstanding
the unenforceability of any such other provision or agreement.

15.  NON-ASSIGNABILITY; TERMINATION

     The rights and obligations of the parties under this Agreement and under
any Transaction shall not be assigned by either party without the prior written
consent of the other party. Subject to the foregoing, this Agreement and any
Transactions shall be binding upon and shall inure to the benefit of the parties
and their respective successors and assigns. This Agreement may be canceled by
either party upon giving written notice to the other, except that this Agreement
shall, notwithstanding such notice, remain applicable to any Transactions then
outstanding.

<PAGE>
 
16.  GOVERNING LAW
     
     This Agreement shall be governed by the laws of the State of New York
without giving effect to the conflict of law principles thereof.

17.  NO WAIVERS, ETC.

     No express or implied waiver of any Event of Default by either party shall
constitute a  waiver of any other Event of Default and no exercise of any remedy
hereunder by any party shall constitute a waiver of its right to exercise any
other remedy hereunder.  No modification or waiver of any provision of this
Agreement and no consent by any party to a departure herefrom shall be effective
unless and until such shall be in writing and duly executed by both of the
parties hereto.  Without limitation on any of the foregoing, the failure to give
a notice pursuant to subparagraphs 4(a) or 4(b) hereof will not constitute a
waiver of any right to do so at a later date.

18.  USE OF EMPLOYEE PLAN ASSETS

     (a) If assets of an employee benefit plan subject to any provision of the
Employee Retirement Income Security Act of 1974 ("ERISA") are intended to be
used by either party hereto (the "Plan Party") in a Transaction, the Plan Party
shall so notify the other party prior to the Transaction.  The Plan Party shall
represent in writing to the other party that the Transaction does not constitute
a prohibited transaction under ERISA or is otherwise exempt therefrom, and the
other party may proceed in reliance thereon but shall not be required so to
proceed.

     (b) Subject to the last sentence of subparagraph (a) of this Paragraph, any
such Transaction shall proceed only if Seller furnishes or has furnished to
Buyer its most recent available audited statement of its financial condition and
its most recent subsequent unaudited statement of its financial condition.

     (c) By entering into a Transaction pursuant to this Paragraph, Seller shall
be deemed (i) to represent to Buyer that since the date of Seller's latest such
financial statements, there has been no material adverse change in Seller's
financial condition which Seller has not disclosed to Buyer, and (ii) to agree
to provide Buyer with future audited and unaudited statements of its financial
condition as they are issued, so long as it is a Seller in any outstanding
Transaction involving a Plan Party.

19.  INTENT

     (a) The parties recognize that each Transaction is a "repurchase agreement"
as that term is defined in Section 101 of Title 11 of the United State Code, as
amended (except insofar as the type of Securities subject to such Transaction or
the term of such Transaction would render such definition inapplicable), and a
"securities contract" as that term is defined in Section 741 of Title 11 of the
United States Code, as amended.

     (b) It is understood that either party's right to liquidate Securities
delivered to it in connection with Transactions hereunder or to exercise any
other remedies pursuant to Paragraph 11 hereof, is a contractual right to
liquidate such Transaction as described in Sections 555 and 559 of Title 11 of
the United States Code, as amended.

20.  DISCLOSURE RELATING TO CERTAIN FEDERAL PROTECTIONS

          The parties acknowledge that they have been advised that:

          (a) in the case of Transactions in which one of the parties is a
     broker or dealer registered with the Securities and Exchange Commission
     ("SEC") under Section 15 of the Securities Exchange Act of 1934 ("1934
     Act"), the Securities Investor Protection Corporation has taken the
     position that the provisions of the Securities Investor Protection Act of
     1970 ("SIPA") do not protect the other party with respect to any
     Transaction hereunder;

          (b) in the case of Transactions in which one of the parties is a
     government securities broker or a government securities dealer registered
     with the SEC under Section 15C of the 1934 Act, SIPA will not provide
     protection to the other party with respect to any Transaction hereunder;
     and

          (c) in the case of Transactions in which one of the parties is a
     financial institution, funds held by the financial institution pursuant to
     a Transaction hereunder are not a deposit and therefore are not insured by
     the Federal Deposit Insurance Corporation, the Federal Savings and Loan
     Insurance Corporation or the National Credit Union Share Insurance Fund, as
     applicable.

                 pass-through security is readily salable to sophisticated
                 investors that purchase similar securities in the secondary
                 mortgage market; and

          (vii)  as of any date of determination, such mortgage pass-through
                 security has not become unsalable as a result of the
                 characteristics of the underlying pool of mortgage loans and/or
                 any material adverse change in the financial condition or
                 results of operations of Obligor or any of its subsidiaries, on
                 a consolidated basis, (provided that temporary market
                 conditions, as determined by MLPF&S in the good faith exercise
                 of its reasonable business judgment, shall not in any event
                 render any mortgage pass-through security unsalable for
                 purposes hereof).

     In addition to the foregoing, either Obligor may, from time to time,

3.   MODIFICATIONS OF PARAGRAPH 11 OF THE MASTER REPURCHASE AGREEMENT.
     ---------------------------------------------------------------- 

     Subparagraph (v) of Paragraph 11 of the Master Repurchase Agreement is
hereby modified in its entirety to read as follows:

     "any representation or warranty made by Seller or Buyer shall have been
     incorrect or untrue in any material respect, when made or repeated or
     deemed to have been made or repeated, provided, however, that such breach
                                           --------  -------                  
     of representation or warranty shall not constitute an Event of Default with
     respect to an Eligible Asset if after taking into account the Market Value
     of the Eligible Assets without taking into account the Eligible Assets with
     respect to which such breach occurred no other Event of Default shall have
     occurred and be continuing."

     Paragraph 11 of the Master Repurchase Agreement is hereby further amended
     by adding new subsections (i) and (j) to such Paragraph:

               (i)  Any sales of Purchased Securities, pursuant to Paragraph
          11(d)(i) of the Agreement, may be effected in a commercially
          reasonable manner in public or private sales as MLPF&S may reasonably
          deem appropriate and at such price or prices as MLPF&S may reasonably
          deem satisfactory.  In the event MLPF&S elects in lieu of so selling
          such Purchased Securities to give an Obligor credit for such Purchased
          Securities, such credit shall be in an amount equal to the Market
          Value thereof as of the date of acceleration.

               (j)  If an Event of Default shall occur and be continuing, MLPF&S
          shall exercise reasonable efforts


                                      I-7
<PAGE>
 
          (the reasonableness of which shall be determined by MLPF&S in its
          discretion in light of the circumstances) to provide notice to an
          Obligor prior to exercising any remedy in respect of an Event of
          Default by such Obligor, provided, however, that notwithstanding
                                   --------  -------
          anything in the Agreement to the contrary, MLPF&S shall not be
          required, prior to exercising any remedy in respect of an Event of
          Default by such Obligor, to give any notice otherwise required
          hereunder, if MLPF&S reasonably believes that (i) the Purchased
          Securities then held by MLPF&S threaten to decline speedily in value
          or (ii) any delay occasioned by the giving of such notice will
          jeopardize MLPF&S's ability to recover, by sale of such Purchased
          Securities or otherwise, all or part of the then outstanding amount
          of the Repurchase Price or of any other amounts payable to MLPF&S or
          any affiliate thereof pursuant hereto. If no prior notice is given,
          MLPF&S shall give notice to the related Obligor of the remedies
          effected by MLPF&S promptly thereafter. MLPF&S may forthwith apply
          the cash, if any, then held by it as part of the Purchased Securities
          relating to any Transaction to the payment of the Repurchase Price,
          and, if there shall be no such cash or the cash so applied shall not
          be sufficient to pay in full the Repurchase Price, may thereafter
          collect, receive, appropriate, retain and realize upon the Purchased
          Securities, or any part thereof, and may forthwith sell, assign,
          contract to sell, or otherwise dispose of and deliver the Purchased
          Securities, or any part thereof, in one or more parcels at such
          public or private sale or sales, at such place or places, at such
          price or prices and upon such other terms and conditions as MLPF&S
          may deem best (provided, however, that MLMCI shall act in a
          commercially reasonable manner), for cash or on credit or for future
          delivery without assumption of any credit risk, with the right of
          MLPF&S upon any such sale or sales to purchase all or any part of the
          Purchased Securities so sold. Upon any sale, transfer or other
          disposition of the Purchased Securities pursuant hereto MLPF&S shall
          have the right to deliver, assign and transfer to the transferee
          thereof the Purchased Securities so sold. Each transferee upon any
          such transfer or other disposition shall hold the property thereby
          acquired by it absolutely free from any claim or right of any kind,
          including any equity or rights of redemption, of either Obligor, each
          of which hereby specifically waives all rights of redemption, stay or
          appraisal which it has or may have under any rule of law or statute
          whether now existing or hereafter adopted (in the latter case, to

                                      I-8
<PAGE>
 
          the extent permitted thereby). Each Obligor agrees that MLPF&S need
          give only such notice of the time and place of any public or private
          sale (including any adjourned private sale) or other intended
          disposition as may be required by market conditions and standards of
          commercial reasonableness and that MLPF&S need not in any event give
          more than five (5) days' notice that such sale or disposition is to
          take place. Each Obligor agrees that the notice provided for in the
          preceding sentence is reasonable notification of such matters.
          
                 MLMCI shall not be obligated to make any sale pursuant to any
          such notice.  MLMCI may, without notice or publication, adjourn any
          public or private sale or cause the same to be adjourned from time to
          time by announcement at the time and place fixed for the sale, and
          such sale may be made at any time or place to which the same may be so
          adjourned, provided that MLMCI shall act in a commercially reasonable
          manner.  In case of any sale of all or any part of the Collateral on
          credit or for future delivery, the Collateral so sold may be retained
          by MLMCI until the selling price is paid by the purchaser thereof, but
          MLMCI shall not incur any liability in case of the failure of such
          purchaser to take up and pay for the Collateral so sold, and, in case
          of any such failure, such Collateral may again be sold upon like
          notice.  MLMCI, however, instead of exercising the power of sale
          herein conferred upon it, may proceed by a suit or suits at law or in
          equity to foreclose the lien and security interest created hereby and
          sell the Collateral, or any portion thereof, under a judgment or
          decree of a court or courts of competent jurisdiction.


              (k)  MLPF&S shall have no obligation to realize upon any Purchased
          Securities, except through proper application of any distributions
          with respect to the Purchased Securities made directly to MLPF&S or
          its agent(s).  Obligor hereby waives the defense of impairment of the
          Purchased Securities; provided, however, that MLPF&S shall act in a
                                --------  -------                            
          commercially reasonable manner.  MLPF&S may in its sole discretion
          elect to realize upon all or a portion of the Purchased Securities by
          giving the Obligor credit for such Purchased Securities, which credit
          shall be in an amount equal to the Market Value thereof as of the date
          of acceleration.

4.   COMMITMENT; DISBURSEMENT OF FUNDS.
     --------------------------------- 

               (i)  Subject to the terms and conditions stated herein, and
          relying upon the representations, warranties and covenants of Obligors
          herein set forth, MLPF&S agrees to enter into one or more Transactions
          with each Assignor.  The outstanding Repurchase Price for both
          Obligors under the Agreement shall be limited to the excess of
          $225,000,000 over the sum of all amounts owed by the Obligors to
          MLPF&S hereunder and all amounts owed by the Obligors to MLMCI under
          the Assignment Agreement.

              (ii)  Obligors agree, jointly and severally, to pay to MLMCI, on
          behalf of MLPF&S hereunder and on behalf of itself under the Master
          Assignment Agreement, a structuring fee applicable to both this
          Agreement and the Master Assignment Agreement in the aggregate amount
          of $1,125,000.00 simultaneously with the execution of this Agreement,
          and the agreement of MLPF&S to enter into Transactions hereunder shall
          not be effective until such structuring fee has been received by
          MLMCI.

             (iii)  Either Obligor may request that the parties enter into a
          transaction hereunder by making a written request, either by mail or
          facsimile transmission, to MLPF&S.  MLPF&S shall pay the Purchase
          Price within two (2) days of receipt of such notice, so long as the
          terms and conditions of this Agreement are fully satisfied and no
          Event of Default hereunder shall have occurred and be continuing.  The
          amount of any such Purchase Price shall be in a minimum amount of
          $1,000,000 and integral multiples of $100,000 in excess thereof.

              (iv)  The Pricing Rate shall be specified in Exhibit I hereto.

5.   CONFIRMATION.
     ------------ 

     (a)  Each Confirmation shall be binding upon Obligors (jointly and
          severally) and MLPF&S unless written notice of objection is given by
          the objecting party to the other parties within two (2) Business Days
          after the objecting party's receipt of the Confirmation.

     (b)  MLPF&S may, but shall not be required to, deliver Confirmations
          confirming periodic adjustments in the Pricing Rate for a particular
          Transaction.

                                     I-10
<PAGE>
 
     (c)  Notwithstanding the last sentence of Paragraph 3(b) of the Master
          Repurchase Agreement, in the event of any conflict between the terms
          of a Confirmation and the Agreement, such Confirmation shall prevail.

6.   MARKET VALUE DETERMINATION.
     -------------------------- 

     (a)  MLPF&S shall determine the Market Value for the Purchased Securities
          in the good faith exercise of its reasonable business judgment from
          time to time and at such time as it may elect in its sole discretion.

     (b)  With respect to any Purchased Security that an Obligor has not
          acquired directly from MLPF&S or any of its affiliates, either (i)
          such Obligor will provide to MLPF&S in a timely manner all data with
          respect thereto that MLPF&S may reasonably request (which, at a
          minimum, shall include (x) either (A) a CMO Passport model for the
          Eligible Asset, if available at such time, or (B) if a CMO Passport
          model is not yet available, price/yield tables prepared by the
          underwriter or placement agent for the Eligible Asset with the CMO
          Passport model to follow within 30 days after the date of issuance of
          the Eligible Asset, and (y) a prospectus and, if applicable, a
          prospectus supplement for the Eligible Asset) or (ii) such Purchased
          Security will be deemed to have a Market Value of zero.

7.   DELIVERY OF PURCHASED SECURITIES AND ADDITIONAL DOCUMENTS.
     --------------------------------------------------------- 

     (a)  The Purchased Securities shall be delivered to MLPF&S registered in
          the name of MLPF&S or, if MLPF&S shall agree in its sole discretion,
          with properly endorsed instruments of transfer (including, without
          limitation, any opinions of counsel and certificates required for
          transfer) that will enable MLPF&S to cause such Purchased Securities
          to be so registered without further action on the part of MLPF&S other
          than delivering such Purchased Securities and such instruments of
          transfer to the appropriate transfer agent.  The right of MLPF&S to
          receive, and the obligation of Obligors to deliver, Purchased
          Securities in the form described in the preceding sentence shall not
          be waived or reduced by MLPF&S's having accepted and received,
          knowingly or unknowingly, Purchased Securities that have not been so
          registered or are not accompanied by such instruments of transfer.

                                     I-11
<PAGE>
 
     (b)  Each Obligor agrees that, from time to time upon the prior written
          request of MLPF&S, it will (i) execute and deliver such further
          documents and do such other acts and things as MLPF&S may reasonably
          request in order to fully effectuate the purposes of the Agreement
          (including, without limitation, the delivery of appropriate transfer
          documentation as contemplated by Paragraph (6)(a) hereof) and (ii)
          provide such opinions of counsel concerning matters relating to the
          Agreement as MLPF&S may reasonably request.

8.   REPRESENTATIONS, WARRANTIES AND COVENANTS.
     ----------------------------------------- 

     (a)  Each party represents and warrants, as of the date of this Agreement
          and as of the Purchase Date of each Transaction, as follows:

          (i)    The execution, delivery and performance of the Agreement and
                 the performance of each Transaction do not and will not result
                 in or require the creation of any lien, security interest or
                 other charge or encumbrance (other than pursuant hereto) upon
                 or with respect to any of its properties;

          (ii)   The Agreement is, and each Transaction when entered into under
                 the Agreement will be, a legal, valid and binding obligation of
                 it enforceable against it in accordance with the terms of the
                 Agreement, subject as to enforcement, to applicable bankruptcy,
                 insolvency, reorganization and similar laws relating to or
                 affecting creditors' rights, to the assumption that enforcement
                 will be undertaken in a commercially reasonable manner, and to
                 general principles of equity, regardless of whether enforcement
                 is sought in a proceeding in equity or at law; and

          (iii)  Since the date of the most recent balance sheet or financial
                 statement delivered by it pursuant to Paragraph 11 hereof,
                 there has been no material adverse change in its financial
                 condition or results of operations.

     (b)  Each Obligor represents and warrants as to each Transaction as of the
          Purchase Date of each Transaction, as follows:

                                     I-12
<PAGE>
 
          (i)    All information provided by such Obligor to MLPF&S concerning
                 the Purchased Securities is true and correct in all material
                 respects;

          (ii)   MLPF&S has a first priority lien on and security interest in
                 the Purchased Securities (including all proceeds, distributions
                 and other amounts realized in respect thereof) in favor of
                 MLPF&S, subject to no prior lien, charge, encumbrance or rights
                 of others, and, assuming that MLPF&S has taken and maintains
                 possession of the Purchased Securities either (A) registered in
                 the name of MLPF&S or its nominee or (B) delivered with such
                 instruments of transfer as provided in Paragraph 7(a) of these
                 Supplemental Terms, no further action, including any filing or
                 recordation of any document, is currently required in order to
                 establish and perfect the liens on and security interests in
                 the Purchased Securities in favor of MLPF&S against any third
                 parties in any jurisdiction;

          (iii)  There are no delinquent federal, state, city, county or other
                 taxes relating to an Obligor, any Purchased Security sold by it
                 to MLPF&S under the Agreement or any arrangement pursuant to
                 which such Purchased Security is issued, and all such tax
                 liabilities have been satisfied except those that are being
                 contested by such Obligor in good faith and with respect to
                 which payment has been stayed by a court of competent
                 jurisdiction; and

          (iv)   Each Purchased Security is an Eligible Asset.


     (c)  Each Obligor covenants with MLPF&S as follows:

          (i)    Obligor will pay and discharge all taxes, levies, liens and
                 other charges on its assets and on the Purchased Securities
                 sold by it to MLPF&S under the Agreement which, in each case,
                 in any manner would create any lien or charge upon such
                 Purchased Securities and which would materially adversely
                 affect the interests of MLPF&S except those that are being
                 contested by such Obligor in good faith and with respect to
                 which payment has been stayed by a court of competent
                 jurisdiction;

                                     I-13
<PAGE>
 
          (ii)   The ratio of total liabilities to equity of each Obligor and
                 its subsidiaries, on a consolidated basis, as determined in
                 accordance with GAAP (but excluding (1) limited purpose finance
                 subsidiaries of Obligor that issue collateralized mortgage
                 obligations and (2) trusts that issue mortgage pass-through
                 certificates and with respect to which an Obligor acts as
                 depositor), shall not at any time exceed 25 to 1; and

          (iii)  The Book Net Worth of Obligor for any two consecutive calendar
                 quarters shall not be less than or equal to 70% of Obligor's
                 Book Net Worth as of the date set forth on the first page
                 hereof; and


9.   EVENTS OF DEFAULT; REMEDIES.
     ---------------------------

                 Value of the Eligible Assets without taking into account the
                 Eligible Assets with respect to which such circumstances have
                 occurred, no other Event of Default shall have occurred and be
                 continuing.

          (iii)  An Obligor shall be in default with respect to any normal and
                 customary covenants under any material contract or agreement
                 (including, without limitation, any Financing Agreement) to

                 such entity expressly assumes by written agreement, executed
                 and delivered to MLPF&S in form and substance satisfactory to
                 MLPF&S, the performance of all of such Obligor's duties and

          (vi)   A final judgment by any competent court in the United States of
                 America for the payment of money in an amount of at least
                 $1,000,000 is rendered against the defaulting party, and the
                 same remains undischarged or unpaid for a period of sixty (60)
                 days during which execution of such judgment is not effectively
                 stayed;

          (vii)  Any representation or warranty made by any party in the
                 Agreement shall have been incorrect or untrue when made or
                 repeated or when deemed to have been made or repeated and the
                 interests of MLPF&S, in the case of a breach by an Obligor, or
                 of an Obligor, in the case of a breach by MLPF&S, shall have
                 been materially adversely affected thereby, and such breach is
                 continuing;

          (viii) Any party shall breach any covenant in the Agreement and the

                 reorganization, arrangement, dissolution or liquidation law, or
                 the initiation of any such proceeding against either Obligor if
                 either Obligor indicates by any act its consent thereto or if
                 such proceeding is not dismissed or stayed within forty-five
                 (45) days;

          (x)    A firm of independent accountants shall have failed to issue an
                 opinion or shall have issued an opinion qualified adversely in
                 any material respect in connection with the most recent audited

     shall be in addition to any other rights of the parties to cause such an
     acceleration under the Agreement.


     (b)  In addition to the other remedies available to the parties upon the
          occurrence and during the continuance of an Event of Default by a
          defaulting party, MLPF&S shall have the following additional remedies

                 would otherwise be authorized to receive pursuant to Paragraph
                 6 of the Agreement shall cease, and all such rights shall
                 thereupon become vested in MLPF&S, which shall thereupon have
                 the sole right to receive such payments and apply them to the
                 amounts owed jointly and severally by Obligors pursuant to the
                 Agreement.

          (ii)   All payments that are received by either Obligor contrary to
                 the provisions of the preceding clause (i) shall be received in
                 trust for the benefit of MLPF&S and shall be segregated from
                 other funds of Obligors and shall be promptly paid to MLPF&S.

     (c)  Any sale of Purchased Securities under Paragraph 11 of the Master
          Repurchase Agreement shall be conducted in a commercially reasonable

          the Purchased Securities, and any other

                                     I-16
<PAGE>

          Fourth, to the payment of any amounts owed by either Obligor to MLMCI,
          ------                                                                
     MLPF&S or any affiliate thereof under a Financing Agreement.

          Fifth, to the payment of any other amounts owed by either Obligor to

     MLMCI or MLPF&S under any other instrument or agreement.

          Sixth, to the payment to the related Obligor, or to such other person

     as a court of competent jurisdiction may direct, of any surplus then
     remaining from such proceeds and other cash.

          As used in the Agreement, "proceeds" of the Purchased Securities shall
     mean cash and other property received  or otherwise realized in respect of
     the Purchased Securities.

     (b)  Expenses incurred in connection with an Event of Default where MLPF&S
          is the nondefaulting party shall include without limitation those
          costs and expenses incurred by MLPF&S as a result of the early
          termination of any repurchase agreement or reverse repurchase
          agreement entered into by MLPF&S in connection with any Transaction.


11.  FINANCIAL STATEMENTS.
     -------------------- 

     (a)  As of the date hereof, MLPF&S and each Obligor shall each provide the
          other with its audited year-end financial statements and its most
          recent publicly available interim financial statement.  MLPF&S and
          each Obligor shall from time to time each provide the other with
          audited year-end financial statements and additional

                                     I-17
<PAGE>
 
          publicly available interim financial statements upon such other
          party's reasonable request.

     (b)  Each Obligor shall provide MLPF&S, at the expense of such Obligor
          without request of MLPF&S, with all financial statements required to
          be filed with the Securities and Exchange Commission in connection
          with an Obligor's 10Q and 10K reports as soon after the filing thereof
          as practicable.

     (c)  Each delivery of Purchased Securities by each Obligor to MLPF&S under
          the Agreement will constitute a representation by such Obligor that
          there has been no material adverse change in such Obligor's financial
          condition not disclosed to MLPF&S since the date of such Obligor's
          most recent unaudited balance sheet or income statement delivered to
          MLPF&S.  Each Obligor shall provide MLPF&S, from time to time at such
          Obligor's expense, with such information concerning Obligor of a
          financial or operational nature as MLPF&S may reasonably request
          promptly upon receipt of such request.

12.  PRICE DIFFERENTIAL; PRICING RATE; REPURCHASE PRICE.
     -------------------------------------------------- 

     (a)  The Price Differential shall be payable in arrears with respect to
          each Transaction, together with the Purchase Price therefor, on the
          termination date for the related Transaction or as may be otherwise
          mutually agreed upon by the parties and as specified in the related
          Confirmation.

     (b)  The Pricing Rate shall be reset monthly on the one-month anniversary
          of the Purchase Date for the Transaction unless otherwise specified in
          the related Confirmation.

     (c)  All calculations of Price Differential shall be made on the basis of a
          360-day year and the actual number of days elapsed.

     (d)  Payment of the Repurchase Price (including the Price Differential)
          shall be made by wire transfer in immediately available funds or in
          such other manner as may be mutually agreed upon by MLPF&S and the
          related Obligor in writing.  Amounts received by MLPF&S after 3:00
          p.m., New York City time, on any Business Day shall be deemed to have
          been paid by the related Obligor and received by MLPF&S on the next
          succeeding Business Day.

13.  ADDITIONAL INFORMATION; CONFIDENTIALITY.
     --------------------------------------- 

                                     I-18
<PAGE>
 
     (a)  Each Obligor agrees to provide to MLPF&S, as received, any payment
          statements, notices or other communications directed to holders of the
          Purchased Securities.

     (b)  Each of the parties hereto acknowledges that the Agreement is
          confidential in nature and each such party agrees that, unless
          otherwise directed by a court or regulatory entity of competent
          jurisdiction or as may be required by federal or state law (which
          determination as to federal or state law shall be based upon written
          advice of counsel), it shall limit the distribution of such document
          to its officers, employees, attorneys, accountants and agents as
          required in order to conduct its business with the other parties
          hereto.  This subparagraph (b) shall not apply to information which
          has otherwise lawfully entered the public domain or which the other
          parties have given written permission to disclose.

14.  MARGIN MAINTENANCE.
     ------------------ 

     Paragraph 4(a) of the Master Repurchase Agreement is hereby modified to
     provide that if the notice to be given by MLPF&S to an Obligor under such
     paragraph is given at or prior to 10:00 a.m. New York City time on a
     Business Day, such Obligor shall transfer the cash or Additional Purchased
     Securities to MLPF&S (in the manner contemplated by the Agreement) prior to
     the close of business in New York City on the date of such notice, and if
     such notice is given after 10:00 a.m. New York City time, such Obligor
     shall transfer the cash or Additional Purchased Securities (in the manner
     as aforesaid) prior to the close of business in New York City on the
     Business Day following the date of such notice.

15.  MLPF&S AS ATTORNEY-IN-FACT.
     -------------------------- 

     Effective upon the occurrence and during the continuation of an Event of
     Default, MLPF&S is hereby appointed the attorney-in-fact of each Obligor
     for the purpose of carrying out the provisions of the Agreement and taking
     any action and executing any instruments which MLPF&S may deem necessary or
     advisable to accomplish the purposes of the Agreement, which appointment as
     attorney-in-fact is irrevocable and coupled with an interest.  Without
     limiting the generality of the foregoing, after an Event of Default has
     occurred and is continuing, MLPF&S shall have the right and power to
     receive, endorse and collect all checks made payable to the order of an
     Obligor representing any

                                     I-19
<PAGE>
 
     distribution in respect of any of the Collateral
     or any part thereof and to give full discharge for the same.

16.  EFFECTS OF APPLICABLE LAW.
     ------------------------- 

     (a)  In the event that any Applicable Law with respect to a Non-Widely
          Traded Security or any Change of Applicable Law with respect to a
          Widely Traded Security results in any material restriction or
          limitation on the corporate power or authority of MLPF&S to enter into
          a proposed Transaction or to continue to maintain an existing
          Transaction with respect to any Security that would otherwise qualify
          as an Eligible Asset, (A) the parties hereto shall in good faith
          negotiate such additional or revised terms to the Agreement as will
          result in a permissible transaction that corresponds to the economic
          equivalent of the arrangement originally contemplated by the parties
          under the Agreement or (B) if such Applicable Law or Change of
          Applicable Law, as the case may be, does not permit such
          renegotiation, the commitment of MLPF&S to enter into or to continue
          to maintain the Transaction with respect to such Security shall be
          cancelled or modified (depending upon the stated effect of the
          Applicable Law or Change of Applicable Law, as appropriate), with such
          cancellation and/or modification to be operative upon the earlier of
          (x) the date required by such Applicable Law or Change of Applicable
          Law, as appropriate, or (y) the date on which the related Obligor has
          secured alternative financing for the affected Security.

     (b)  In the event that any Applicable Law with respect to a Non-Widely
          Traded Security or any Change of Applicable Law with respect to a
          Widely Traded Security results in any adverse economic effect on
          MLPF&S that is material with respect to the particular Transaction,
          the parties hereto shall in good faith negotiate such additional or
          revised terms related to pricing that will result in a Transaction
          that corresponds to the economic equivalent of the arrangement
          originally contemplated by MLPF&S and Obligors.

17.  TERMINATION.
     ----------- 

     (a)  Notwithstanding any provisions of Paragraph 15 of the Master
          Repurchase Agreement to the contrary, the Agreement and all
          Transactions outstanding hereunder shall terminate automatically
          without any requirement for notice on the date occurring on the
          earlier of (i) two years after the date set forth on the first page

                                     I-20
<PAGE>
 
          hereof and (ii) the written agreement of Obligors and MLPF&S;
          provided, however, that notwithstanding the foregoing, the Agreement
          --------  -------                                                   
          shall continue in full force and effect until any outstanding
          Repurchase Price has been paid in full.  Upon termination of the
          Agreement and the payment of the Repurchase Price with respect to all
          Transactions, MLPF&S shall release its lien and security interest
          under the Agreement and assign, transfer and deliver, against receipt,
          any remaining Purchased Securities and money received in respect
          thereof to or on the order of the related Obligor.  Upon the request
          of the related Obligor, MLPF&S will then execute termination
          statements and such other documents as such Obligor may reasonably
          request as are necessary to make clear upon the public record the
          termination of the lien and security interests created the Agreement
          with respect to the Purchased Securities.

     (b)  If, at any time prior to the date seventeen (17) months after the date
          of the Agreement, Obligors request that MLPF&S renew the Agreement for
          an additional term of mutually acceptable duration, MLPF&S will notify
          Obligors not later than the date eighteen (18) months after the date
          of the Agreement if it will so renew the Agreement; provided, however,
                                                              --------  ------- 
          that (i) no such agreement to renew the term of the Agreement shall
          preclude MLPF&S from thereafter declining to enter into Transactions
          hereunder either (A) pursuant to any provision set forth in the
          Agreement or (B) if there is a material adverse change in the
          financial condition or results of operations, of an Obligor or any of
          its subsidiaries and (ii) the foregoing shall not preclude Obligors
          from requesting the renewal of the term of the Agreement at any other
          time.

18.  RIGHT OF SET-OFF.
     ---------------- 

     MLPF&S shall have the right to apply any distributions on the Purchased
     Securities and the proceeds of the sale thereof pursuant to the Agreement
     against any amounts owed by either Obligor to MLMCI, MLPF&S or any
     affiliate thereof under any other instrument or agreement (including,
     without limitation, any Financing Agreement).  The right of set-off
     provided for herein shall not diminish any other rights (whether of set-
     off, contribution or otherwise) that MLPF&S and its affiliates may have
     with respect to the Purchased Securities and the distributions thereon and
     the proceeds thereof.

                                     I-21

19.  JOINT AND SEVERAL LIABILITY OF OBLIGORS.
     --------------------------------------- 

     The Obligors agree to be jointly and severally liable for the obligations
     of either Obligor hereunder and all representations, warranties, covenants
     and agreements made by or on behalf of either or both Obligors in the
     Agreement or in any exhibit hereto or any document, instrument or
     certificate delivered pursuant hereto shall be deemed to have been made by
     each Obligor, jointly and severally.  The Obligors further agree that,
     notwithstanding any right of MLPF&S to investigate fully the affairs of the
     Obligors and notwithstanding any knowledge of facts determined or
     determinable by MLPF&S, MLPF&S has the right to rely fully on the
     representations, warranties, covenants and agreements of either or both
     Obligors contained in the Agreement and upon the accuracy of any document,
     instrument, certificate or exhibit given or delivered hereunder.  The joint
     and several obligation of each Obligor hereunder is absolute,
     unconditional, irrevocable, present and continuing and, with respect to any
     payment to be made to MLPF&S, is a guaranty of payment (and not of
     collectability) and is in no way conditional or contingent upon the
     continued existence of the other Obligor.  Any notice or other
     communication provided to one Obligor pursuant hereto shall be deemed to
     have been given to both Obligors and failure to be sent any notice or
     communication contemplated hereby and delivered to the other Obligor shall
     not relieve an Obligor from its joint and several liability for the
     obligations of the other Obligor hereunder.

20.  CONSENT TO JURISDICTION.
     ----------------------- 

     Notwithstanding any termination of the Agreement, each Obligor hereby
     agrees that any legal action or proceeding against either Obligor in
     connection with the Agreement may be brought in the courts of the State of
     New York or of the United States of America located in the City and State
     of New York, Borough of Manhattan, as MLPF&S may elect, and each Obligor
     hereby irrevocably submits to the non-exclusive jurisdiction of each of
     said courts, and waives any objection on the grounds of venue, forum non
     conveniens or similar ground.

          organization and (B) are Mortgage-Related Securities;

     2.   20%-30% for Eligible Assets that either (A) are rated AAA or AA (or
          the equivalent) by at least one nationally recognized statistical
          rating organization but are not Mortgage-Related Securities or (B) are
          rated A or BBB (or the equivalent) by at least one nationally
          recognized statistical rating organization;

     3.   25%-30% for Eligible Assets that are rated BB or B (or the equivalent)
          by at least one nationally recognized statistical rating organization;

The percentage for calculating Buyer's Margin Amount for each Transaction will

time on the date of determination ("LIBOR"):

          AAA or AA (or the equivalent) by at least one nationally recognized
          statistical rating organization;
