Balance of such Class, until it has been reduced to zero;]

applicable.]

         (b)      All distributions or allocations made with respect to each

         No Bond in certificated form shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose, unless there appears
on such Bond a certificate of authentication substantially in the form provided
for in the related Series Supplement executed by the Trustee by the manual
signature of one of its authorized Officers, and such certificate upon any Bond
shall be conclusive evidence, and the only evidence, that such Bond has been
duly authenticated and delivered hereunder.

Section 3.04.  [Reserved].

Section 3.05.  Registration, Registration of Transfer and Exchange.

         The Depositor shall cause to be kept a "Bond Register" in which,
subject to such reasonable regulations as it may prescribe, the Depositor shall
provide for the registration of Bonds and the registration of transfers of Bonds
in certificated form. The Trustee is hereby initially appointed "Bond Registrar"
for the purpose of registering Bonds and transfers of Bonds in certificated form
as herein provided.

         If a Person other than the Trustee is appointed by the Depositor as
Bond Registrar, the Depositor will give the Trustee prompt written notice of the
appointment of a Bond Registrar and of the location, and any change in the
location, of the Bond Register, and the Trustee shall have the right to inspect
the Bond Register at all reasonable times and to obtain copies thereof and the
right to rely upon a certificate executed on behalf of the Bond Registrar by an
Officer thereof as to the names and addresses of the Holders of the Bonds and
the principal amounts and numbers of such Bonds.

         Upon surrender for registration of transfer of any Bond in certificated
form at the office or agency of the Depositor to be maintained as provided in
Section 9.02, the Depositor shall execute, and the Trustee shall authenticate
and deliver, in the name of the designated transferee or transferees, one or
more new Bonds of any authorized denominations of the same Series and Class and
of a like aggregate principal amount.

         At the option of the Holder, Bonds in certificated form may be
exchanged for other Bonds of the same Series and Class in any authorized
denominations and of the like aggregate principal amount, upon surrender of such
Bonds to be exchanged at such office or agency. Whenever any Bonds in
certificated form are so surrendered for exchange, the Depositor shall execute,
and the Trustee shall authenticate and deliver, the Bonds that the Bondholder
making the exchange is entitled to receive.

         All Bonds in certificated form issued upon any registration of transfer
or exchange of Bonds shall be the valid obligations of the Depositor, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Bonds surrendered upon such registration of transfer or exchange.

         Every such Bond presented or surrendered for registration of transfer
or exchange shall (if so required by the Depositor or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form

                                      -18-
<PAGE>   25
satisfactory to the Depositor and the Trustee duly executed by the Holder
thereof or his attorney duly authorized in writing with such signature
guaranteed by a commercial bank or trust company located, or having a
correspondent located, in the City of New York or the city in which the
Corporate Trust Office is located, or by a member firm of a national securities
exchange, and by such other documents as the Trustee may require.

         No service charge shall be made to a Holder for any registration of
transfer or exchange of Bonds in certificated form, but the Depositor may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of such Bonds, other than exchanges pursuant to Section 3.04 and 10.06
not involving any transfer.

         Payment and transfer procedures for Bonds in Book-Entry form shall be
as specified in the related Series Supplement.

Section 3.06.  Mutilated, Destroyed, Lost or Stolen Bonds.

         If (a) any mutilated Bond is surrendered to the Trustee, or the
Depositor and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Bond, and (b) there is delivered to the
Depositor and the Trustee such security or indemnity as may be required by them
to save each of them harmless, then, in the absence of notice to the Depositor
or the Bond Registrar that such Bond has been acquired by a bona fide purchaser,
the Depositor shall execute and upon its request the Trustee shall authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Bond, a new Bond of the same Series, Class, tenor and principal
amount, bearing a number not contemporaneously outstanding; provided, however,
that if any such mutilated, destroyed, lost or stolen Bond shall have become or
shall be about to become due and payable, or shall have been selected or called
for redemption, instead of issuing a new Bond, the Depositor may pay such Bond
without surrender thereof, except that any mutilated Bond shall be surrendered.
If, after the delivery of such new Bond or payment of a destroyed, lost or
stolen Bond pursuant to the proviso to the preceding sentence, a bona fide
purchaser presents for payment such original Bond, the Depositor and the Trustee
shall be entitled to recover such new Bond (or such payment) from the Person to
whom it was delivered or any Person taking such new Bond from such Person,
except a bona fide purchaser thereof, and shall be entitled to recover upon the
security or indemnity provided therefor to the extent of any loss, damage, cost
or expenses incurred by the Depositor or the Trustee in connection therewith.

         Upon the issuance of any new Bond under this Section, the Depositor may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other reasonable expenses
(including the fees and expenses of the Trustee) connected therewith.

         Every new Bond issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Bond shall constitute an original
additional contractual obligation of the Depositor, whether or not the
mutilated, destroyed, lost or stolen Bond shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Bonds of the same Series and Class duly
issued hereunder.

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

Section 3.07.  Payment of Principal and Interest; Principal and Interest Rights
Preserved.

         (a) The Current Interest Bonds of each Class shall bear interest for
each Due Period at the Bond Interest Rate for the Bonds of such Class, which
interest shall be due and payable on each Payment Date on the unpaid principal
amount of the Bonds of such Class determined as of the Accounting Date relating
to such Payment Date, commencing on the date specified in the related Series
Supplement and continuing on each Payment Date thereafter until the entire
unpaid principal amount of the Bonds of such Class is paid, whether by
acceleration or otherwise, and (to the extent lawful and enforceable) shall bear
interest on overdue interest at the Bond Interest Rate for the Bonds of such
Class.

         (b) Until the entire unpaid principal balance of each Class of Bonds of
a Series with a prior Stated Maturity is paid in full or such other date as
specified in the related Series Supplement, interest for each Due Period on any

                                      -19-
<PAGE>   26
Accretion Bonds of the same Series shall be compounded at the Bond Interest Rate
of such Accretion Bonds on each Accounting Date for that Class on the unpaid
Compound Value of such Accretion Bonds determined as of such Accounting Date,
commencing on the first Accounting Date for such Class as specified in the
related Series Supplement, and on each Accounting Date thereafter.

         On the Payment Date on which the entire unpaid principal balance of
each Class of Bonds of a Series with a prior Stated Maturity is paid in full or
such other date as specified in the related Series Supplement, any remaining
portion of the amount then payable on such Payment Date shall be paid as
interest on the Accretion Bonds of the same Series and, to the extent that such
amount is less than the amount of the interest accrued on such Accretion Bonds
for the immediately preceding Due Period, the difference shall be added to the
Compound Value of the Bonds of such Class as of the Accounting Date preceding
that Payment Date. Thereafter, such Accretion Bonds shall bear interest at the
Bond Interest Rate for such Accretion Bonds, which interest shall be due and
payable for each Due Period on each Payment Date on the unpaid Compound Value of
such Accretion Bonds determined as of the Accounting Date immediately preceding
such Payment Date until the entire unpaid Compound Value of such Accretion Bonds
is paid, whether by acceleration or otherwise, and (to the extent lawful and
enforceable) shall bear interest on overdue interest at the Bond Interest Rate
for the Bonds of such Class. Notwithstanding the foregoing, in the event that
each Class of Current Interest Bonds of a Series with a prior Stated Maturity is
paid in full and that the payment of principal and interest on the Mortgage
Collateral securing such Series is insufficient at that time to pay the full
amount of required interest on any Accretion Bond on any Payment Date, the
amount of interest that is not available shall be added to the Compound Value of
such Accretion Bonds.

         (c) The principal of the Bonds of a Series shall be payable as
specified in the related Series Supplement until the entire unpaid principal
balance of the Bonds of such Series is paid. All payments of principal of the
Bonds of a Class within a Series shall be allocated on a pro rata basis.

         (d) Interest on and principal of Bonds issued in certificated form
shall be payable by check (subject to collection) mailed to the Person entitled
thereto at his address as it appears on the Bond Register, except for the final
payment due on Maturity of a certificated Bond of a Series, which, unless
otherwise provided by a Series Supplement, shall be made only upon presentation
and surrender of such Bond at the office or agency of the Depositor maintained
for that purpose as provided in Section 9.02. In the case of any certificated
Bond upon which the final payment is due on the Maturity of such Bond, the
Depositor or, at the Depositor's request, the Trustee in the name and at the
expense of the Depositor, shall notify the Person entitled thereto at his
address as it appears on the Bond Register that such Bond is to be paid in full.
Such notice shall be mailed as soon as practicable, and in any event no later
than the Payment Date on which the final payment is to be made on such Bond, and
shall specify the place where such Bond may be presented and surrendered for
final payment. If so provided in the related Series Supplement, upon timely
receipt by the Trustee of instructions and the payment of any required charge or
fee, the Trustee may make payments of principal and interest to certain
Bondholders by wire transfer of immediately available funds.

         (e) Except to the extent provided in Section 6.21 or as may be
otherwise specifically provided by Series Supplement, interest on and principal
of the Bonds of a Series shall be payable solely from the proceeds of the Trust
Estate Granted in the related Series Supplement.

         (f) The Holders of the Bonds of a Class as of the Record Date in
respect of a Payment Date shall be entitled to the interest accrued and payable
and principal payable on such Payment Date with respect to the Bonds of such
Class. Payments of principal to such Holders shall be made in the proportion
that the unpaid principal balance of the Bonds of such Class registered in the
name of each such Holder on such Record Date bears to the aggregate unpaid
principal balance of all Bonds of such Class on such Record Date. Any such
payments that are mailed and returned to the Paying Agent shall be held for
payment as herein provided at the office or agency of the Depositor to be
maintained as provided in Section 9.02.

         (g) Unless otherwise provided in the related Series Supplement, any
interest on the Bonds of a Series that is payable, but is not punctually paid or
duly provided for, on any Payment Date ("Defaulted Interest") shall forthwith
cease to be payable to the Holder on the relevant Record Date by virtue of
having been such Holder; and such Defaulted Interest shall be paid by the
Depositor, at its election in each case, as provided in Clause (1) or Clause (2)
below:

                                      -20-
<PAGE>   27

                  (1)      The Depositor may elect to make payment of any
         Defaulted Interest to the Holders of the Bonds of such Series as of the
         close of business on a record date for the payment of such Defaulted
         Interest (the "Special Record Date"), which shall be fixed in the
         following manner. The Depositor shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Bond and
         the date of the proposed payment, which date shall be no earlier than
         [___] days after such notification (unless a shorter time shall be
         acceptable to the Trustee), and at the same time the Depositor shall
         deposit with the Trustee an amount of money equal to the aggregate
         amount proposed to be paid in respect of such Defaulted Interest or
         shall make arrangements satisfactory to the Trustee for such deposit
         prior to the date of the proposed payment, such money when deposited to
         be held in trust for the benefit of the Persons entitled to such
         Defaulted Interest as in this Clause provided. Thereupon the Trustee
         shall fix a Special Record Date for the payment of such Defaulted
         Interest which [shall be not more than [___] nor less than [___] days
         prior to the date of the proposed payment and not less than [___] days
         after the receipt by the Trustee of the notice of the proposed
         payment.] The Trustee shall promptly notify the Depositor of such
         Special Record Date and the Depositor shall either mail, or cause to be
         mailed, notice of the proposed payment of such Defaulted Interest and
         of the Special Record Date. Such notice shall be sent by first-class
         mail, postage prepaid, to each Holder of Bonds of such Series at his
         address as it appears in the Bond Register, [not less than ___] days
         prior to such Special Record Date. Notice of the proposed payment of
         such Defaulted Interest and of the Special Record Date therefor having
         been mailed as aforesaid, such Defaulted Interest shall be paid to the
         Holders of the Bonds of such Series as of the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following Clause (2).

                  (2)      The Depositor may make payment of any Defaulted
         Interest in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which the Bonds may be
         listed, and upon such notice as may be required by such exchange, if,
         after notice given by the Depositor to the Trustee of the proposed
         payment pursuant to this Clause, such manner of payment shall be deemed
         practicable by the Trustee.

         (h) Subject to the foregoing provisions of this Section, each Bond of a
Series delivered under this Indenture and the related Series Supplement upon
registration of transfer of or in exchange for or in lieu of any other Bond
shall carry the rights to unpaid interest and principal that were carried by
such other Bond.

Section 3.08.  Persons Deemed Owners.

         Prior to due presentment for registration of transfer of any Bond, the
Depositor, the Trustee and any agent of the Depositor or of the Trustee may
treat the Person in whose name any Bond is registered as the owner of such Bond
for the purpose of receiving payments of principal, premium, if any, and
interest on such Bond and for all other purposes whatsoever (whether or not such
Bond is overdue), and neither the Depositor, the Trustee nor any agent of the
Depositor or the Trustee shall be affected by notice to the contrary.

Section 3.09.  Cancellation.

         All Bonds surrendered for payment, registration of transfer, exchange
or redemption shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly canceled by it. The Depositor may
at any time deliver to the Trustee for cancellation any Bonds previously
authenticated and delivered hereunder that the Depositor may have acquired in
any manner whatsoever, and all Bonds so delivered shall be promptly canceled by
the Trustee. No Bonds shall be authenticated in lieu of or in exchange for any
Bonds canceled as provided in this Section, except as expressly permitted by
this Indenture. All canceled Bonds held by the Trustee shall be destroyed unless
the Depositor shall direct by a Depositor Order that they be returned to it.

Section 3.10.  [Reserved].

Section 3.11.  Limited Right to Substitute Collateral.

         (a) Unless otherwise provided in the related Series Supplement, on any
Subsequent Delivery Date for any Series, the Depositor shall have the right to
pledge to the Trustee under a Series Supplement as security for the Series, in
substitution for any one or more

                                      -21-
<PAGE>   28
items of Original Mortgage Collateral securing such Series, one or more items of
Substitute Mortgage Collateral as long as each such item of Substitute Mortgage
Collateral has (a) a Collateral Value at least equal to the Collateral Value of
the item of Original Mortgage Collateral for which such item of Substitute
Mortgage Collateral is substituted, in each case determined on the last
preceding Due Date with respect to such item of Mortgage Collateral before
taking into account payments received by the Trustee on such Due Date, and (b)
an interest rate within one percentage point of, and a [Maturity Date within ___
days] of, such item of Original Mortgage Collateral for which it is substituted.

                  On the Subsequent Delivery Date, the Depositor shall have the
right to deliver and pledge to the Trustee as security for the Series in
exchange for each such item of Original Mortgage Collateral (1) the item of
Substitute Mortgage Collateral plus (2) cash in an amount equal to the payment
of principal and interest paid or to be paid on such Substitute Mortgage
Collateral during the month of the Subsequent Delivery Date.

                  Upon such substitution, all of the Depositor's right, title
and interest to the item of Substitute Mortgage Collateral shall be assigned to
the Trustee pursuant to Section 4.02(2) or (3) of this Indenture, and the
Depositor shall receive (1) the item of Original Mortgage Collateral for which
the item of Substitute Mortgage Collateral was substituted and (2) all
Collateral Proceeds received on the Due Date in the month of the Subsequent
Delivery Date by the Trustee on the item of Original Mortgage Collateral
delivered to the Depositor. The Trustee shall also receive, not later than the
Subsequent Delivery Date, an Officer's Certificate of the Depositor and of the
Master Servicer to the effect that:

                  (1)      all instruments furnished to the Trustee in
         connection with such substitution conform in all material respects to
         the requirements of this Indenture and the related Series Supplement
         and constitute sufficient authority hereunder for the Trustee to permit
         the substitution then applied for;

                  (2)      all conditions precedent provided for in this
         Indenture and the related Series Supplement relating to the
         substitution then applied for have been complied with and the Depositor
         is duly entitled to effect such substitution; and

                  (3)      each item of Substitute Mortgage Collateral has been
         duly and validly assigned to the Trustee free and clear of any lien,
         mortgage, pledge, charge, security interest or other encumbrance that
         is prior to the lien of the Indenture, and each Mortgage Certificate
         either has been registered in the name of the Trustee, its agent or
         nominee or has been delivered to the Trustee for registration in the
         name of the Trustee, its agent or nominee.

         (b) The Depositor shall also have the right to pledge, under a
Supplement, on any date:

                  (1)      in substitution of one or more items of Mortgage
         Collateral directly securing such Series, one or more collateralized
         mortgage obligations secured by the same items of Mortgage Collateral;
         or

                  (2)      in substitution of one or more collateralized
         mortgage obligations pledged to secure such Series and secured by
         Mortgage Collateral, a direct pledge of the Mortgage Collateral that
         secured the collateralized mortgage obligations provided, however, that
         in each case the Trustee shall have received a writing addressed to the
         Trustee from each Rating Agency to the effect that such substitution
         will not result in the lowering of its then rating of such Series of
         Bonds.

         (c) Notwithstanding any other provision of this Section to the contrary
(i) the Depositor's right to substitute Mortgage Collateral is limited to
substitutions that are made pursuant to the terms of, and that take place within
the time constraints provided in, the Sales Agreement and (ii) any item of
Substitute Mortgage Collateral that is a Mortgage Loan must be a Qualified
Substitute Mortgage Loan.

Section 3.12.  Book-Entry Bonds.

         If the Series Supplement for a Series so provides, Bonds of the Series
shall be issued initially as a single certificate in the name of a Clearing
Agency maintaining book-entry records with respect to ownership and transfer of
Book-Entry Bonds of such Series, or its nominee. In such case, the Trustee shall
deal with the Clearing Agency and Clearing Agency Participants as
representatives of the Beneficial Owners of Book-Entry Bonds of such Series

                                      -22-
<PAGE>   29
for purposes of exercising the rights of Bondholders hereunder, and the rights
of Beneficial Owners with respect to such Book-Entry Bonds shall be limited to
those established by law and agreements between such Beneficial Owners and the
Clearing Agency and Clearing Agency Participants. Beneficial Owners of
Book-Entry Bonds shall not be entitled to certificates for the Book-Entry Bonds
as to which they are the Beneficial Owners. Requests and directions from, and
votes of, such representatives shall not be deemed to be inconsistent if they
are made with respect to different Beneficial Owners. Without the consent of the
Depositor and the Trustee, a Book-Entry Bond may not be transferred by the
Clearing Agency except to another Clearing Agency that agrees to hold the
Book-Entry Bond for the account of the Beneficial Owners.

         Loans not later than [______] calendar days following the Delivery Date
         for a Series, which recordation shall be an expense of the Depositor.
         For each Mortgage Loan for which an assignment is not duly and timely

         to withdraw the Mortgage Loan from the lien of the Indenture pursuant
         to the provisions of Section 12.11 hereof. As evidence of recordation,

         certification from a title insurance company, (ii) an Opinion of
         Counsel, (iii) a recorded assignment or (iv) a clerk's receipt as to
         the recordation of any or all of the assignments.

<PAGE>   34

                  (2)      the Depositor has paid or caused to be paid all other

                                   ARTICLE SIX

                                    REMEDIES

Section 6.01.  Events of Default.

         "Event of Default" with respect to any Series shall have the meaning
set forth in the related Series Supplement.

Section 6.02.  Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to the Bonds of a Series occurs and
is continuing then and in every such case the Trustee or the Holders of not less
than [___%] in principal balance of the Outstanding Bonds of such Series (voting
as a group with respect to such Series) may declare the principal of all the
Bonds of such Series affected thereby to be immediately due and payable, by a
notice in writing to the Depositor (and to the Trustee if given by Bondholders),
and upon any such declaration such principal, together with accrued and unpaid
interest thereon to the date of such acceleration, shall become immediately due
and payable. Notwithstanding the foregoing, if an Event of Default with respect
to the Bonds of a Series occurs and is continuing solely as the result of an
order or judgment arising out of a Proceeding, which order or judgment prevents
the application by the Trustee, as provided in this Indenture, of the proceeds
of one or more items of Mortgage Collateral included in the Trust Estate for
such Series, the Trustee shall declare to be immediately due and payable by lot
among all Classes of Bonds of such Series, by notice in writing to the
Depositor, and upon any such declaration there shall become due and payable,
Bonds of such Series in a principal amount equal to the Collateral Values of
such Mortgage Collateral. The Bonds to become so due and payable shall be
allocated by Class among the Series on the basis of the principal amount of
Bonds attributable to such Mortgage Collateral. The Bonds to become so due and
payable will be allocated among Classes within the Series on the basis of the
principal amount of Bonds within each Class attributable to the Mortgage
Collateral sold by the Trustee. Such declarations and any other remedial action
in connection therewith by the Trustee shall be the sole remedy for the Holders
of Bonds of such Series upon the happening of such occurrence.

         At any time after such a declaration of acceleration of Maturity has
been made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in principal balance of the Outstanding Bonds of the Series that has
been declared due and payable as herein provided, by written notice to the
Depositor and the Trustee, may rescind and annul such declaration and its
consequences if:

         (1) (a)  the Depositor has paid or deposited with the Trustee a sum
                  sufficient to pay

                                      -28-
<PAGE>   35

                                    (i)      all overdue installments of
                           interest and principal on all Bonds of such Series,

                                    (ii)     to the extent that payment of such
                           interest is lawful, interest upon overdue
                           installments of interest on the Bonds of such Series
                           at the applicable Bond Interest Rates for such
                           Series, and

                                    (iii)    all sums paid or advanced by the
                           Trustee hereunder and the reasonable compensation,
                           expenses, disbursements and advances of the Trustee,
                           its agents and counsel; and

                                    (b)      all Events of Default with respect
                  to a Series, other than the non-payment of the interest or
                  principal of Bonds of such Series that have become due solely
                  by such acceleration, have been cured or waived as provided in
                  Section 6.15; or

                  (2)      an election is made to act in accordance with the
         provisions of Section 6.05 with respect to the Event of Default with
         respect to the Bonds of such Series that gave rise to such declaration.

No such rescission shall affect any subsequent Default or impair any right
consequent thereon.

Section 6.03.  Collection of Indebtedness and Suits for Enforcement by Trustee.

         The Depositor covenants that if Default is made in the payment of any
principal of or interest on any Bond of any Series, the Depositor will, upon
demand of the Trustee, pay to it, for the benefit of the Holder of such Bond of
such Series, but only from the Trust Estate securing the Bonds of such Series,
the whole amount then due and payable on such Bond for principal and interest,
with interest upon the overdue principal and, to the extent that payments of
such interest shall be legally enforceable, upon overdue installments of
interest, at the Bond Interest Rate for such Bond, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

         If the Depositor fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as Trustee of an express trust, may institute a
Proceeding for the collection of the sums so due and unpaid, and may prosecute
such Proceeding to judgment or final decree, and may enforce the same against
the Depositor or any other obligor upon the Bonds and collect the monies
adjudged or decreed to be payable in the manner provided by law.

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Bondholders by such appropriate Proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy or
legal or equitable right vested in the Trustee by this Indenture or by law. Any
proceedings brought by the Trustee on behalf of the Bondholders or any
Bondholder against the Depositor shall be limited to the preservation,
enforcement and foreclosure of the liens, assignments, rights and security
interests under the Indenture and no attachment, execution or other unit or
process shall be sought, issued or levied upon any assets, properties or funds
of the Depositor, other than the Trust Estate relative to the Bonds in respect
of which such Event of Default has occurred. If there is a foreclosure of any
such liens, assignments, rights and security interests under this Indenture, by
private power of sale or otherwise, no judgment for any deficiency upon the
indebtedness represented by the Bonds may be sought or obtained by the Trustee
or any Bondholder against the Depositor. The Trustee shall be entitled to
recover the costs and expenses expended by it pursuant to this Article V
including reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

         In case there shall be pending Proceedings relative to the Depositor or
any other obligor upon the Bonds under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Depositor or its property or such other obligor or its
property, or in case of any other comparable judicial Proceedings relative to
the Depositor or other obligor upon the Bonds of any Series, or the creditors or
property of the Depositor or such other

                                      -29-

obligor, the Trustee, regardless whether the principal of any Bonds shall then
be due and payable as therein expressed or by declaration or otherwise and
regardless whether the Trustee shall have made any demand pursuant to the
provisions of this Section 6.03, shall be entitled and empowered, by
intervention in such Proceedings or otherwise:

                  (a)      to file and prove a claim or claims for the whole
         amount of principal and interest owing and unpaid in respect of the
         Bonds of any Series, and to file such other papers or documents as may
         be necessary or advisable in order to have the claims of the Trustee
         (including any claim for reasonable compensation to the Trustee and
         each predecessor Trustee, and their respective agents, attorneys and
         counsel, and for reimbursement of all expenses and liabilities
         incurred, and all advances made, by the Trustee and each predecessor
         Trustee, except as a result of negligence or bad faith) and of the
         Bondholders allowed in any Proceedings relative to the Depositor or
         other obligor upon the Bonds of any Series, or to the creditors or
         property of the Depositor or such other obligor;

                  (b)      unless prohibited by applicable law and regulations,
         to vote on behalf of the Holders of the Bonds of any Series in any
         election of a trustee or a standby trustee in arrangement,
         reorganization, liquidation or other bankruptcy or insolvency
         Proceedings or person performing similar functions in comparable
         Proceedings; and

                  (c)      to collect and receive any monies or other property
         payable or deliverable on any such claims, and to distribute all
         amounts received with respect to the claims of the Bondholders and of
         the Trustee on their behalf; and any trustee, receiver or liquidator,
         custodian or other similar official is hereby authorized by each of the
         Bondholders to make payments to the Trustee, and, in the event that the
         Trustee shall consent to the making of payments directly to the
         Bondholders, to pay to the Trustee such amounts as shall be sufficient
         to cover reasonable compensation to the Trustee, each predecessor
         Trustee and their respective agents, attorneys and counsel, and all
         other expenses and liabilities incurred, and all advances made, by the
         Trustee and each predecessor Trustee except as a result of negligence
         or bad faith.

         Amounts payable to the Trustee under this section are intended to
constitute administrative expenses. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or vote for or accept or adopt
on behalf of any Bondholder any plan of reorganization, arrangement, adjustment
or composition affecting the Bonds of any Series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Bondholder in any such Proceeding except, as aforesaid, to vote for the election
of a trustee in bankruptcy or similar person.

         In any Proceedings brought by the Trustee (and also any Proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Bonds, and it shall not be necessary to make any Holders of the Bonds
parties to any such Proceedings.

Section 6.04.  Remedies.

         (a)      If an Event of Default with respect to any Series shall have
occurred and be continuing and the Bonds for such Series have been declared due
and payable and such declaration and its consequences have not been rescinded
and annulled, the Trustee may, for the benefit of the Bondholders, do one or
more of the following:

                  (i)      institute Proceedings for the collection of all
         amounts then payable on the Bonds of such Series or under this
         Indenture, whether by declaration or otherwise, enforce any judgment
         obtained, and collect from the Trust Estate securing the Bonds of such
         Series and from the Depositor monies adjudged due, subject in all cases
         to the provisions of Sections 9.01 and 6.03;

                  (ii)     in accordance with Section 6.18, sell all or a
         portion of the Trust Estate securing the Bonds of such Series or rights
         of interest therein, at one or more public or private sales called and
         conducted in any manner permitted by law;

                  (iii)    institute Proceedings from time to time for the
         complete or partial foreclosure of this Indenture with respect to the
         Trust Estate securing the Bonds of such Series;

                                      -30-
<PAGE>   37

                  (iv)     exercise any remedies of a secured party under the
         Uniform Commercial Code and take any other appropriate action to
         protect and enforce the rights and remedies of the Trustee or the
         Holders of the Bonds of such Series hereunder; and

                  (v)      refrain from selling the Trust Estate and apply all
         monies collected pursuant to Section 6.08;

Section 6.05.  [Reserved].

Section 6.06.  Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial Proceeding relative to the Depositor or any other obligor upon the
Bonds of any Series or the property of the Depositor or of such other obligor,
the Trustee (regardless whether the principal of the Bonds of such Series shall
then be due and payable as therein expressed or by declaration or otherwise and
regardless whether the Trustee shall have made any demand on the Depositor for
the payment of overdue principal or interest) shall be entitled and empowered,
by intervention in such Proceeding or otherwise:

                  (i)      to file and prove a claim for the whole amount of
        principal and interest owing and unpaid in respect of the Bonds of such
         Series and to file such other papers or documents as may be necessary
         or advisable in order to have the claims of the Trustee (including any
         claim for the reasonable compensation, expenses, disbursements and
         advances of the Trustee, its agents and counsel) and of the Holders of
         the Bonds of such Series allowed in such judicial Proceeding; and

                  (ii)     to collect and receive any monies or other property
         payable or deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, liquidator, or sequestrator (or other
similar official) in any such judicial Proceeding is hereby authorized by each
Holder of Bonds of such Series to make such payments to the Trustee, and in the
event that the Trustee shall consent to the making of such payments directly to
the Holders of the Bonds of such Series, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of Bonds of
such Series any plan of reorganization, arrangement, adjustment or composition
affecting the Bonds of such Series or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Bondholder in any
such Proceeding.

Section 6.07.  Trustee May Enforce Claims Without Possession of Bonds.

         All rights of action and claims under this Indenture or the Bonds of
any Series may be prosecuted and enforced by the Trustee without the possession
of any of the Bonds of such Series or the production thereof in any Proceeding
relating thereto, and any such Proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Bonds in respect of which such
judgment has been recovered.

Section 6.08.  Application of Money Collected.

         Except as provided in Section 6.21, if applicable, any money collected
by the Trustee with respect to the Bonds of any Series pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
or interest, upon presentation of the Bonds of such Series and the notation
thereon of such payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST: To reimbursement of the Trustee for all expenses associated with
the disposition of all or a portion of the Trust Estate or the exercise of any
of the other remedies set forth in this Article Six;

                                      -31-

         SECOND: To reimburse the Master Servicer, the Trustee and the Depositor
for advances made with respect to the Mortgage Loans;

         THIRD: To the payment of the Bonds;

         FOURTH: To reimburse the Reserve Fund, if any, for amounts drawn on it

         SIXTH: To the Depositor or any other Person legally entitled thereto,
any remaining funds.

Section 6.09.  Limitation on Suits.

         No Holder of any Bond of a Series shall have any right to institute any
Proceedings, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

                  (1)      such Holder has previously given written notice to
         the Trustee of a continuing Event of Default in respect of such Series;

                  (2)      the Holders of not less than [___%] in principal
         balance of the Outstanding Bonds of such Series shall have made written
         request to the Trustee to institute Proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3)      such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (4)      the Trustee for [___] days after its receipt of such
         notice, request and offer of indemnity has failed to institute any such
         Proceeding; and

                  (5)      no direction inconsistent with such written request
         has been given to the Trustee during such [___]-day period by the
         Holders of a majority in principal balance of the Outstanding Bonds of
         such Series;

it being understood and intended that no one or more Holders of Bonds of a
Series shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other Holders of Bonds of such Series or to obtain or to seek to obtain
priority or preference over any other Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all the Holders of Bonds of such Series.

         In the event the Trustee shall receive conflicting or inconsistent
requests and indemnity from two or more groups of Holders of Bonds, each
representing less than a majority of the then aggregate Outstanding balance of
the Outstanding Bonds of such Series, the Trustee in its sole discretion may
determine what action, if any, shall be taken, notwithstanding any other
provisions of this Indenture.

Section 6.10.  Unconditional Rights of Bondholders to Receive Principal and
Interest.

         Notwithstanding any other provision in this Indenture other than
Section 3.07(g), and subject to the provisions of the related Series Supplement
and any related Supplement the Holder of any Bond shall have the right, which is
absolute and unconditional, to receive payment of the principal of and interest
on such Bond as such principal and interest become due and payable and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

Section 6.11.  Restoration of Rights and Remedies.

         If the Trustee or any Bondholder has instituted any Proceeding to
enforce any right or remedy under this Indenture and such Proceeding has been
discontinued or abandoned for any reason, or has been determined

                                      -32-
<PAGE>   39

adversely to the Trustee or to such Bondholder, then and in every such case the
Depositor, the Trustee and the Bondholder shall, subject to any determination in
such Proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Trustee and
the Bondholders shall continue as though no such Proceeding had been instituted.

Section 6.12.  Rights and Remedies Cumulative.

         No right or remedy herein conferred upon or reserved to the Trustee or
to the Bondholder is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 6.13.  Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Bond to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Bondholders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Bondholders, as the
case may be.

Section 6.14.  Control by Bondholders.

         The Holders of a majority in principal balance of the Outstanding Bonds
of each Series affected (voting as one Class with respect to each Series) shall
have the right to direct the time, method and place of conducting any Proceeding
for any remedy available to the Trustee with respect to the Bonds of such Series
or exercising any trust or power conferred on the Trustee with respect to such
Series; provided that:

                  (1)      such direction shall not be in conflict with any rule
         of law or with this Indenture;

                  (2)      any direction to the Trustee to undertake a sale of
         the Trust Estate shall be by the Holders of the Bonds representing the
         percentage of the principal balance of the Outstanding Bonds specified
         in Section 6.18(b)(1), unless Section 6.18(b)(2) is applicable; and

                  (3)      the Trustee may take any other action deemed proper
         by the Trustee that is not inconsistent with such direction; provided,
         however, that, subject to Section 7.01, the Trustee need not take any
         action that it determines might involve it in liability or be unjustly
         prejudicial to the Bondholders not consenting.

Section 6.15.  Waiver of Past Defaults.

         The Holders of a majority in principal balance of the Outstanding Bonds
of any Series may on behalf of the Holders of all the Bonds of such Series waive
any past Default with respect to such Series and its consequences, except a
Default:

                  (1)      in the payment of the principal of or interest on any
         Bond of such Series unless an election to act in accordance with the
         provisions of Section 6.05 shall have been made and not been rescinded;
         or

                  (2)      in respect of a covenant or provision hereof that
         under Section 10.02 cannot be modified or amended without the consent
         of the Holder of each Outstanding Bond affected.

         Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

                                      -33-
<PAGE>   40
Section 6.16.     Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Bond by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Bondholder, or group of Bondholders,
holding in the aggregate more than [___%] in principal balance of the
Outstanding Bonds of a Series, or to any suit instituted by any Bondholder for
the enforcement of the payment of the principal of or interest on any Bond on or
after the Stated Maturity expressed in such Bond (or, in the case of redemption,
on or after the applicable Redemption Date or Special Redemption Date).

Section 6.17.     Waiver of Stay or Extension Laws; Non-Petition.

         Each Holder of a Bond shall be deemed to have agreed, by its acceptance
thereof, to not file, or join in filing, any petition in bankruptcy or commence
any similar proceeding in respect of the Depositor for a period of one year and
one day following the payment in full of such Bond.

         The Depositor covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Depositor (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

Section 6.18.     Sale of Trust Estate.

         (a)      The power to effect any sale of any portion of the Trust
Estate securing a Series pursuant to Section 6.04 shall not be exhausted by any
one or more Sales as to any portion of such Trust Estate remaining unsold but
shall continue unimpaired until the entire Trust Estate securing the Bonds of
such Series shall have been sold or all amounts payable on the Bonds of such
Series and under this Indenture with respect thereto shall have been paid. The
Trustee may from time to time postpone any Sale by public announcement made at
the time and place of such Sale. The Trustee hereby expressly waives its right
to any amount fixed by law as compensation for any Sale.

         (b)      To the extent permitted by law, the Trustee shall not in any
private Sale sell or otherwise dispose of the Trust Estate, or any portion
thereof, unless:

                  (1)      the Holders of Bonds representing not less than
         [___%] of the principal balance of the Outstanding Bonds of any Series
         consent to or direct the Trustee to make such Sale; or

                  (2)      the proceeds of such Sale would be not less than the
         entire amount that would be payable to the Holders of the Bonds of such
         Series, in full payment thereof in accordance with the Series
         Supplement for such Series, on the Payment Date next succeeding the
         date of such Sale.

                  The purchase by the Trustee of all or any portion of the Trust
Estate at a private Sale shall not be deemed a Sale or disposition thereof for
purposes of this Section 6.18(b).

         (c)      Unless the Holders of all Outstanding Bonds of any Series have
otherwise consented or directed the Trustee, at any public Sale of all or any
portion of the Trust Estate at which a minimum bid equal to or greater than the
amount described in paragraph (2) of subsection (b) of this Section 6.18 has not
been established by the Trustee and no Person bids an amount equal to or greater
than such amount, Trustee, acting in its capacity as Trustee on behalf of the
Bondholders, shall prevent such sale and bid an amount (which shall include the
Trustee's right, in its capacity as Trustee, to credit bid) [at least $1.00]
more than the highest other bid in order to preserve the Trust Estate on behalf
of the Bondholders.

                                      -34-
<PAGE>   41

         (d)      In connection with a Sale of all or any portion of the Trust
Estate:

                  (1)      any Holder or Holders of Bonds of any Series may bid
         for and purchase the property offered for Sale, and upon compliance
         with the terms of sale may hold, retain and possess and dispose of such
         property, without further accountability, and may, in paying the
         purchase money therefor, deliver any Outstanding Bonds or claims for
         interest thereon in lieu of cash up to the amount that shall, upon
         distribution of the net proceeds of such Sale, be payable thereon, and
         such Bonds, in case the amounts so payable thereon shall be less than
         the amount due thereon, shall be returned to the Holders thereof after
         being appropriately stamped to show such partial payment;

                  (2)      the Trustee may bid for and acquire the property
         offered for Sale in connection with any public Sale thereof, and, in
         lieu of paying cash therefor, may make settlement for the purchase
         price by crediting the gross Sale price against the sum of (A) the
         amount that would be payable to the Holders of the Bonds as a result of
         such Sale in accordance with the Series Supplement for such Series on
         the Payment Date next succeeding the date of such Sale and (B) the
         expenses of the Sale and of any Proceedings in connection therewith
         which are reimbursable to it, without being required to produce the
         Bonds in order to complete any such Sale or in order for the net Sale
         price to be credited against such Bonds, and any property so acquired
         by the Trustee shall be held and dealt with by it in accordance with
         the provisions of this Indenture;

                  (3)      the Trustee shall execute and deliver an appropriate
         instrument of conveyance transferring its interest in any portion of
         the Trust Estate in connection with a Sale thereof;

Neither the lien of this Indenture nor any rights or remedies of the Trustee or

         The recitals contained herein and in the Bonds, except the certificates
of authentication on the Bonds, shall be taken as the statements of the

Indenture or of the Bonds. The Trustee shall not be accountable for the use or
application by the Depositor of Bonds or the proceeds thereof or any money paid
to the Depositor or upon Depositor Order pursuant to the provisions hereof.

Section 7.05.     May Hold Bonds.

                  (a)      The Trustee, any Paying Agent, any Bond Registrar or
         any other agent of the Depositor, in its individual or any other
         capacity, may become the owner or pledgee of Bonds and, subject to
         Sections 7.08 and 7.13, may otherwise deal with the Depositor with the
         same rights it would have if it were not Trustee, Paying Agent, Bond
         Registrar or such other agent.

                  (b)      The Trustee or one or more of its Affiliates may

         and the Trustee further may, from time to time, be the depository of
         custodial accounts with respect to one or more of such Mortgage groups
         or pools of Mortgage Loans. It is expressly recognized and agreed by
         all parties hereto, and each Holder of a Bond by acceptance thereof
         shall be deemed to have agreed, that, in the Event of Default under one
         or more Servicing Agreements, the Trustee, or one or more of its
         Affiliates, as custodian of one or more groups or pools of Mortgage

         responsibilities and interests of the Trustee hereunder.

                  (c)      The Trustee, or one or more of its Affiliates, may
         enter into one or more custodial agreements with one or more Master
         Servicers of the Mortgage Loans or other persons acceptable to the
         Depositor and the Rating Agency, to act as custodian of the Loan

<PAGE>   44

for interest on any money received by it hereunder except as otherwise agreed
upon by the Depositor and except to the extent of income or other gain on
investments that are obligations of the Trustee, in its commercial capacity, and
income or other gain actually received by the Trustee on investments, which are
obligations of others.

Section 7.07.     Compensation and Reimbursement.

         The Depositor agrees:

                  (1)      to pay the Trustee, from time to time, reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                  (2)      except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents, including its attorneys, except any such expense, disbursement
         or advance as may be attributable to its negligence or bad faith); and

                  (3)      to indemnify the Trustee and any director, officer,
         employee or agent of the Trustee for any loss, liability or expense
         (including costs and expenses of litigation, and of investigation,

         incurred in connection with the Trustee's (i) enforcing its rights and
         remedies and protecting the interests, and enforcing the rights and
         remedies, of the Bondholders during the continuance of an Event of
         Default, (ii) defending or prosecuting any legal action in respect of
         this Indenture or the Bonds, (iii) being the mortgagee of record with
         respect to the Mortgage Loans and the owner of record with respect to
         any Mortgaged Property acquired in respect thereof for the benefit of
         Bondholders, or (iv) acting or refraining from acting in good faith at
         the direction of the holders of the related Series of Bonds entitled to
         not less than [___%] of the Voting Rights for such Series; provided,
         however, that such indemnification will not extend to any loss,
         liability or expense that constitutes a specific liability of the
         Trustee pursuant to this Indenture, or to any loss, liability or
         expense incurred by reason of willful misfeasance, bad faith or
         negligence on the part of the Trustee in the performance of its
         obligations and duties hereunder, or by reason of its reckless
         disregard of such obligations or duties, or as may arise from a breach
         of any representation, warranty or covenant of the Trustee made herein.

         To secure the Trustee's right to receive amounts pursuant to this
Section 7.07, the Trustee shall have a lien against the Trust Estate, which lien
shall at all times be subordinate to the lien in favor of the Bondholders. The
Trustee hereby agrees not to cause the filing of a petition in bankruptcy
against the Depositor for the non-payment to the Trustee of any amounts provided
by this Section 7.07 until at least [___] days after the payment in full of all
Bonds issued under this Indenture.

Section 7.08.     Disqualification.

         Irrespective of whether this Indenture is qualified under the TIA, this
Indenture shall always have a Trustee who satisfies the requirements of TIA
Sections 310(a)(1) and 310(a)(5). The Trustee shall always have a combined
capital and surplus as stated in Section 7.09. The Trustee shall be subject to
TIA Section 310(b).

Section 7.09.     Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder that shall (a) (i) be a
corporation organized and doing business under the laws of the United States of
America or of any State, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, or (ii)
be a member of a bank holding system, having a combined capital and surplus of

shall at all times be at least the amount specified in Section 310(a)(2) of the
TIA, (b) be subject to supervision or examination by federal or state authority
and (c) have an office within the United States of America. If such corporation
publishes reports of condition at least annually, pursuant to law or to the

purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of

                                      -38-
<PAGE>   45

condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the affect hereinafter specified in this Article.

Section 7.10.     Resignation and Removal; Appointment of Successor.

         (a)      No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 7.11.

         (b)      The Trustee may resign at any time with respect to one or more
Series of Bonds by giving written notice thereof to the Depositor. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within [___] days after the giving of such notice of resignation,
the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

         (c)      The Trustee for any Series may be removed at any time by Act
of the Holders of a majority in principal amount of the Outstanding Bonds of
such Series, delivered to the Trustee and to the Depositor. The Trustee for any
Series may be removed at any time by the Depositor provided that the Depositor
receives confirmation that the appointment of the successor Trustee will not
result in the lowering of the rating of that Series of Bonds.

         (d)      If at any time:

                  (1)      the Trustee shall have a conflicting interest
         prohibited by Section 7.08 with respect to any Series of Bonds and
         shall fail to resign or eliminate such conflicting interest in
         accordance with Section 7.08 after written request therefor by the
         Depositor or by any Bondholder who has been a bona fide Holder of a
         Bond for at least [six months]; or

                  (2)      the Trustee shall cease to be eligible under Section
         7.09 and shall fail to resign after written request therefor by the
         Depositor or by any such Bondholder; or

                  (3)      the Trustee shall become incapable of acting with
         respect to any Series of Bonds or shall be adjudged a bankrupt or
         insolvent or a receiver or liquidator of the Trustee or of its property
         shall be appointed or any public officer shall take charge or control
         of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation;

then, in any such case, (i) the Depositor by a Board Resolution may remove the
Trustee, and the Depositor shall join with the Trustee in the execution,
delivery and performance of all instruments and agreements necessary or proper
to appoint a successor Trustee and to vest in such successor Trustee any
property, title, right or power deemed necessary or desirable, subject to the
other provisions of this Indenture; provided, however, if the Depositor does not
make such appointment within [______] days after the receipt by it of a request
to do so, or in case an Event of Default has occurred and is continuing, the
Trustee may petition a court of competent jurisdiction to make such appointment,
or (ii) subject to Section 6.16, and, in the case of a conflicting interest as
described in clause (1) above, unless the Trustee's duty to resign has been
stayed as provided in TIA Section 310(b), any Bondholder who has been a bona
fide Holder of a Bond for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

         (e)      If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of the Trustee for any cause,
the Depositor, by a Board Resolution, shall promptly appoint a successor
Trustee. If within one year after such resignation, removal or incapability or
the occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal balance of the Outstanding Bonds of that
Series delivered to the Depositor and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed by
the Depositor. If no successor Trustee shall have been so appointed by the
Depositor or the Bondholders and shall have accepted appointment in the manner
hereinafter provided, any Bondholder who has been a bona fide Holder of a Bond
for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

                                      -39-
<PAGE>   46

         (f)      The Depositor shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of the applicable Series of Bonds as their names and addresses appear in
the Bond Register. Each notice shall include the name of the successor Trustee
and the address of its Corporate Trust Office.

Section 7.11.     Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Depositor and the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee with respect to all or any applicable Series shall become effective, and
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts, duties and obligations with
respect to such Series of the retiring Trustee; but, on request of the Depositor
or the successor Trustee, such retiring Trustee shall, upon payment of its
charges then unpaid, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder, subject nevertheless to its
lien, if any, provided for in Section 7.07. Upon request of any such successor
Trustee, the Depositor shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

         If a successor Trustee is appointed with respect to the Bonds of one or
more (but not all) Series, the Depositor, the predecessor Trustee and each
successor Trustee with respect to the Bonds of any applicable Series shall
execute and deliver an agreement supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Bonds of any Series as to which the predecessor Trustee is not retiring shall
continue to be vested in the predecessor Trustee, and shall add to or change any
of the provisions of this Indenture as shall be necessary to provide for or
facilitate the administration of the trusts hereunder by more than one Trustee,
it being understood that nothing herein or in such supplemental agreement shall
constitute such Trustees co-Trustees of the same trust and that each such
Trustee shall be a Trustee of a trust or trusts under separate indentures.

         No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article and the Trustee or an Affiliate of the Trustee shall be approved by
Fannie Mae or Freddie Mac as a seller-servicer of Mortgage Loans.

Section 7.12.     Merger, Conversion, Consolidation or Succession to Business
                  or Trustee.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Bonds have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Bonds so authenticated with the same effect as if
such successor Trustee had itself authenticated such Bonds.

Section  7.13.    Preferential Collection of Claims Against Depositor.

         The Trustee (and any co-trustee or separate trustee) shall be subject
to TIA Section 311(a), excluding any creditor relationship listed in TIA Section
311(b), and a Trustee (and any co-trustee or separate trustee) who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated.

Section 7.14.     Co-Trustees and Separate Trustees.

         At any time or times, for the purpose of meeting the legal requirements
of the TIA or of any jurisdiction in which any of the Trust Estate may at the
time be located, the Depositor shall have power to appoint, and upon the written
request of the Trustee or of the Holders of Bonds representing more than [___%]
of the principal balance of the Outstanding Bonds with respect to which a
co-trustee or separate trustee is being appointed, the Depositor shall

                                      -40-
<PAGE>   47

for such purpose join with the Trustee in the execution, delivery and
performance of all instruments and agreements necessary or proper to appoint one
or more Persons approved by the Trustee either to act as co-trustee, jointly
with the Trustee, of all or any part of the Trust Estate, or to act as separate
trustee of any such property, in either case with such powers as may be provided
in the instrument of appointment, and to vest in such Person or Persons in the
capacity aforesaid, any property, title, right or power deemed necessary or
desirable, subject to the other provisions of this Section. If the Depositor
does not join in such appointment within [__ days] after the receipt by it of a
request to do so, or in case an Event of Default has occurred and is continuing,
the Trustee alone shall have power to make such appointment. All fees and
expenses of any co-trustee or separate trustee shall be payable by the
Depositor.

         Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right or power, any and all
such instruments shall, on request, be executed, acknowledged and delivered by
the Depositor.

         Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms:

                  (1)      The Bonds shall be authenticated and delivered and
         all rights, powers, duties and obligations hereunder in respect of the
         custody of securities, cash and other personal property held by, or
         required to be deposited or pledged with, the Trustee hereunder, shall
         be exercised, solely by the Trustee.

                  (2)      The rights, powers, duties and obligations hereby
         conferred or imposed upon the Trustee in respect of any property
         covered by such appointment shall be conferred or imposed upon and

         co-trustee or separate trustee jointly, as shall be provided in the

         or separate trustee appointed under this Section, and, in case an Event
         of Default has occurred and is continuing, the Trustee shall have power
         to accept the resignation of, or remove, any such co-trustee or
         separate trustee without the concurrence of the Depositor upon the
         written request of the Trustee, the Depositor shall join with the
         Trustee in the execution, delivery and performance of all instruments
         and agreements necessary or proper to effectuate such resignation or
         removal. A successor to any co-trustee or separate trustee so resigned

Trustee Mortgage Loan File are included therein, and shall deliver to the Seller
and the Master Servicer on the Closing Date an Initial Certification in the form
attached hereto as Exhibit A-1 with respect to each Mortgage Loan to the effect
that, except as specifically noted on a schedule of exceptions thereto, (A) all
documents required to be contained in the Trustee Mortgage Loan File are in its
possession, (B) such documents have been reviewed by it and appear regular on
their face and relate to such Mortgage Loan, and (C) based on its examination
and only as to the foregoing documents, the information set forth on the related
Mortgage Loan schedule accurately reflects information set forth in the Trustee

                                      -41-
<PAGE>   48

         It is understood that before making the Initial Certification, the
Security Instrument Trustee shall examine the related Mortgage Loan Documents to
confirm that:

                  (1)      each Note and Security Instrument bears an original
         signature or signatures purporting to be that of the Person or Persons
         named as the maker and mortgagor/trustor or, if photocopies are
         permitted, that such copies bear a reproduction of such signature or
         signatures;

                  (2)      except for the endorsement to the Trustee, neither
         the Security Instrument nor any Assignment, on the face or the reverse
         side(s) thereof, contains evidence of any unsatisfied claims, liens,
         security interests, encumbrances or restrictions on transfer;

                  (3)      the principal amount of the indebtedness secured by
         the related Security Instrument is identical to the original principal
         amount of the related Note;

                  (4)      the Assignment of the related Security Instrument
         from the Seller to the Trustee bears an original signature of the
         Seller and any other necessary party (or signatures purporting to be
         that of the Seller and any such other party) or, if photocopies are
         permitted, that such copies bear a reproduction of such signature or
         signatures;

                  (5)      if intervening Assignments are included in the
         Trustee Mortgage Loan File, each such intervening Assignment bears an
         original signature of the related mortgagee and/or the assignee (and
         any other necessary party) (or signatures purporting to be that of each
         such party) or, if photocopies are permitted, that such copies bear a
         reproduction of such signature or signatures;

                  (6)      if either a Title Insurance Policy, a preliminary
         title report or a written commitment to issue a Title Insurance Policy
         is delivered, the address of the real property set forth in such
         policy, report or written commitment is identical to the real property
         address contained in the related Security Instrument; and

                  (7)      if any of a Title Insurance Policy, certificate of
         title insurance or a written commitment to issue a Title Insurance
         Policy is delivered, such policy, certificate or written commitment is
         for an amount not less than the original principal amount of the
         related Note and such title insurance policy insures that the related
         Security Instrument creates a first lien, senior in priority to all
         other deeds of trust, mortgages, deeds to secure debt, financing
         statements and security agreements and to any mechanics' liens,
         judgment liens or writs of attachment (or if the title insurance policy
         or certificate of title insurance has not been issued, the written
         commitment for such insurance obligates the insurer to issue such
         policy for an amount not less than the original principal amount of the
         related Note).

         (b)      Final Certification. On or before one year following the
Closing Date, the Trustee shall deliver to the Seller and the Master Servicer a
Final Certification in the form attached hereto as Exhibit A-2 evidencing the
completeness of the Trustee Mortgage Loan File for each Mortgage Loan, except as
specifically noted on a schedule of exceptions thereto.

         (c)      Certification Generally. In giving each of the Initial
Certification and the Final Certification, the Trustee shall be under no duty or
obligation (1) to inspect, review or examine any such documents, instruments,
securities or other papers to determine that they or the signatures thereto are
genuine, enforceable, or appropriate for the represented purpose or that they
have actually been recorded or that they are other than what they purport to be
on their face or (2) to determine whether any Trustee Mortgage Loan File should
include a flood insurance policy, any rider, addenda, surety or guaranty
agreement, power of attorney, buy down agreement, assumption agreement,
modification agreement, written assurance or substitution agreement.

         (d)      Recordation Report. No later than the [_____ Business Day of
each _____ month,] the Trustee shall deliver to the Master Servicer a
recordation report dated as of the first day of such month, identifying those
Mortgage Loans for which it has not yet received (1) an original recorded
Security Instrument or a copy thereof certified to be true and correct by the
public recording office in possession of such Security Instrument or (2) an
original recorded Assignment of the Security Instrument to the Trustee and any
required intervening Assignments or

                                      -42-
<PAGE>   49

a copy thereof certified to be a true and correct copy by the public recording
office in possession of such Assignment.

         The Depositor will pay or cause to be duly and punctually paid the
principal of, and interest on, the Bonds of each Series in accordance with the
terms of the Bonds and this Indenture solely, except to the extent provided in
Section 6.21, from proceeds of the Trust Estate for such Series Granted
hereunder and under the related Series Supplement and from such assets as may at
any time be pledged to secure payment of the Bonds, and the Depositor shall not
otherwise be liable for payment on the Bonds. No person shall be personally

                                      -44-
<PAGE>   51

Indenture may be served. The Depositor hereby initially appoints the Trustee
such office or agency. The Depositor will give prompt written notice to the
Trustee of the location, and of any change in the location, of any such office
or agency. If at any time the Depositor shall fail to maintain any such office
or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office, and the Depositor hereby appoints the Trustee at its
Corporate Trust Office as its agent to receive all such presentations,
surrenders, notices and demands.

Section 9.03.     Money for Bond Payments to Be Held in Trust.

         If the Depositor shall at any time act as its own Paying Agent, it
will, on or before each Payment Date, Redemption Date or Special Redemption Date
for a Series of Bonds, segregate and hold in trust for the benefit of the Person
entitled thereto a sum sufficient to pay the principal or interest so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and will promptly notify the Trustee of its action or failure
so to act.

         Whenever the Depositor shall have one or more Paying Agents, the
Trustee will, on or before each Payment Date, Redemption Date or Special
Redemption Date for a Series of Bonds, deposit with such Paying Agent cash,
Certificates of Deposit or a Letter of Credit in an amount sufficient to pay the
principal or interest so becoming due (to the extent funds are then available
for such purposes), such sum to be held in trust for the benefit of the Persons
entitled to such principal or interest, and (unless such Paying Agent is the
Trustee) the Depositor will promptly notify the Trustee of its action or failure
so to act.

         The Depositor will cause each Paying Agent, other than the Trustee, to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

                  (1)      hold all sums held by it for the payment of principal
         of or interest on the Bonds in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as herein provided and pay such sums to such
         Persons as herein provided;

                  (2)      give the Trustee notice of any Default by the
         Depositor (or any other obligor upon the Bonds) in the making of any
         payment of principal or interest; and

                  (3)      at any time during the continuance of any such
         Default, upon the written request of the Trustee, forthwith pay to the
         Trustee all sums so held in trust by such Paying Agent.

         The Depositor may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Depositor Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Depositor or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Depositor or such Paying Agent; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Depositor, in trust for the payment of the principal of or interest on
any Bond and remaining unclaimed for [______] years after such principal or
interest has become due and payable to the Holder of such Bond (or if earlier,
[____ months] before the date on which such amount would escheat to a
governmental entity under applicable law) shall be discharged from such trust
and paid to the Depositor; and the Holder of such Bond shall thereafter, as an
unsecured general creditor, look only to the Depositor for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money (but only to the extent of the amounts so paid to the Depositor), and all
liability of the Depositor as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such release of payment, may at the expense of the Depositor cause to be
published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in New York, New York
and in the city in which the Corporate Trust Office is located, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than [___ days] from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Depositor. The
Trustee may adopt and employ, at the expense of the Depositor, any reasonable
means of notification of such release of payment

                                      -45-
<PAGE>   52

(including, but not limited to, mailing notice of such release to Holders whose
Bonds have been called but have not been surrendered for redemption or whose
right to or interest in monies due and payable but not claimed is determinable
from the records of the Trustee or any Paying Agent, at the last address of
record of each such Holder).

Section 9.04.     Corporate Existence.

         The Depositor will keep in full effect its existence, rights and
franchises as a corporation under the laws of the State of Delaware (unless it
becomes incorporated under the laws of any other state or the United States of
America in which case the Depositor will keep in full effect its existence,
rights and franchises as a corporation under the laws of such other
jurisdiction) and will obtain and preserve its qualification to do business as a
foreign corporation in each jurisdiction in which such qualification is or shall
be necessary to protect the validity and enforceability of this Indenture and
the Bonds.

Section 9.05.     Protection of Trust Estate.

         (a)      The Depositor will from time to time execute and deliver all
such supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,
and will take such other action as the Trustee deems necessary or advisable to:

                  (i)      grant more effectively all or any portion of the
         Trust Estate for a Series;

                  (ii)     maintain or preserve the lien (and the priority
         thereof) of this Indenture or to carry out more effectively the
         purposes hereof;

                  (iii)    perfect, publish notice of, or protect the validity
         of any Grant made or to be made by this Indenture;

                  (iv)     enforce any of the Loan Documents, GNMA Certificates,
         Freddie Mac Certificates, Fannie Mae Certificates or Other Mortgage
         Certificates; or

                  (v)      preserve and defend title to the Trust Estate
         securing a Series and the rights therein of the Trustee and the Holders
         of Bonds of such Series secured thereby against the claims of all
         persons and parties.

         (b)      The Trustee shall not remove any portion of the Trust Estate
that consists of money or is evidenced by an instrument, certificate or other
writing from the jurisdiction in which it was held at the date of the most
recent Opinion of Counsel delivered pursuant to Section 9.06 (or from the
jurisdiction in which it was held, or to which it is intended to be removed, as
described in the Opinion of Counsel delivered at the Closing Date pursuant to
the Series Supplement, if no Opinion of Counsel has yet been delivered pursuant
to Section 9.06) or cause or permit ownership or the pledge of any portion of
the Trust Estate that consists of book-entry securities to be recorded on the
books of a Person located in a different jurisdiction from the jurisdiction in
which such ownership or pledge was recorded at such time unless the Trustee
shall have first received an Opinion of Counsel to the effect that the lien and
security interest created by this Indenture with respect to such property will
continue to be maintained after giving effect to such action or actions.

         (c)      The Depositor hereby designates the Trustee its agent and
attorney-in-fact to execute any financing statement, continuation statement or
other instrument required by the Trustee pursuant to this Section 9.05.

         (d)      The Depositor shall pay or cause to be paid any taxes levied
on the account of the beneficial ownership by the Depositor or an Affiliate of
the Depositor of Mortgage Collateral that secures a Series of Bonds.

Section 9.06.     Opinions as to Trust Estate.

         (a)      The Depositor shall deliver to the Trustee, by the [first day
of the fifth month] following the Delivery Date for each Series, one of the
following: (i) an Opinion of Counsel reasonably satisfactory in form and
substance to the Trustee stating that, in the opinion of such counsel, such
action has been taken with respect to the recording and filing of this

as is necessary to

                                      -46-
<PAGE>   53

make effective the lien and security interest of this Indenture with respect to
the Trust Estate for such Series and reciting the details of such action; or
(ii) an Opinion of Counsel stating that, in the opinion of such counsel, no such
action is necessary to make such lien and security interest effective; or (iii)
with respect to each Mortgage Loan pledged to secure a Series, a certificate of
the Depositor in a form acceptable to the Trustee (a "Certificate of
Nonrecordation") to the effect that (A) the Trustee has received all scheduled
payments of principal and interest on such Mortgage Loan, and (B) recordation of
the Trustee's interest in such Mortgage Loan is not yet practicable because the
applicable local recording office has been unable to provide the Master Servicer
or the Depositor with all the information necessary to record the assignment of
the Mortgage Loan to the Trustee, or because of another administrative matter
beyond the reasonable control of the Master Servicer or the Depositor.

         With respect to each Mortgage Loan as to which the Depositor delivers a
Certificate of Nonrecordation, the Depositor shall, by the first day of the
following month, deliver an Opinion of Counsel meeting the requirements of
either of clauses (i) or (ii) above or another Certificate of Nonrecordation.

         With respect to each Mortgage Loan pledged to secure a Series, the
Depositor shall, by the [first day of the twelfth month] following the Delivery
Date for such Series, deliver an Opinion of Counsel meeting the requirements of
either of clauses (i) or (ii) above or require the Master Servicer to withdraw
such Mortgage Loan from the lien of this Indenture pursuant to Section 12.11.

         (b)      On or before [______] of each calendar year (commencing in the
year following the Delivery Date for a Series) the Depositor shall furnish to
the Trustee an Opinion of Counsel meeting the requirements of either of clauses
(i) or (ii) of subsection (a) above (except with respect to any Mortgage Loan as
to which a Certificate of Nonrecordation has been delivered by the Depositor by
the first day of June). Such Opinion of Counsel shall include a description of
any recording, filing, re-recording and refiling of this Indenture, any
indentures supplemental hereto and any other requisite documents that will, in
the opinion of such counsel, be required to maintain the lien and security
interest of this Indenture with respect to the Trust Estate for such Series
until [_____] of the following calendar year.

Section 9.07.     Performance of Obligations; Servicing Agreement.

         (a)      The Depositor shall punctually perform and observe all of its
obligations under this Indenture and the Servicing Agreement with respect to
each Series.

         (b)      The Depositor shall not take any action, and will use its Best
Efforts not to permit any action to be taken by others, that would release any
Person from any of such Person's covenants or obligations under any of the Loan
Documents or under any instrument included in the Trust Estate for a Series, or
that would result in the amendment, hypothecation, subordination, termination or
discharge of, or impair the validity or effectiveness of, any of the Loan
Documents or any such instrument with respect to such Series, except as

         (b)      Notwithstanding paragraph (a) hereof, the Depositor may sell,
transfer, exchange or otherwise dispose of its interest in the Mortgage

that:

                  (1)      all right, title and interest so transferred shall be

                  (2)      each Rating Agency rating the earlier Series of Bonds
         confirms in a writing delivered to the Trustee that such subsequent
         pledge will not result in the withdrawal or downgrading of the rating
         it assigns to any Outstanding Series of Bonds.

                  (3)      the Depositor shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel each stating that such
         consolidation, merger, conveyance or transfer and such supplemental

pursuant to any indenture other than this Indenture secured principally by
mortgage collateral [(which may include mortgage loans, GNMA Certificates,
Freddie Mac Certificates, Fannie Mae Certificates, Other Mortgage Certificates,
or other interests in mortgage loans and, to the extent that any such mortgage
collateral represents an interest in or is secured by mortgage loans, such
mortgage loans)] or (c) the establishment of trusts to acquire, own, hold, sell,
and otherwise deal in or with mortgage collateral; provided, however, that if
such other bonds have a rating lower than the lowest rating of any Outstanding
Bonds of any Series, such lower rating will not, at the time of the issuance of

thereof may not cause the filing of a petition in bankruptcy or take any similar
action against the Depositor until at least [___ days] after all indebtedness
represented by each Outstanding Bond is paid in full; and (v) will not adversely

Section 9.14.     Substitution of Insurance Policies, Etc.; Notification of
                  Rating Agencies.

         (a)      Provided that the conditions set forth in paragraph (b) hereof
have been satisfied, the Depositor may substitute a replacement policy or
instrument for any Bond Insurance, Mortgagor Bankruptcy Fund or Mortgagor
Bankruptcy Bond, Primary Mortgage Insurance Policy, Pool Insurance Policy,
Special Hazard Insurance Policy or Special Hazard Fund or a surety bond or
Letter of Credit pledged to secure any one or more Series of Bonds.

         (b)      The Depositor shall notify each Rating Agency rating the Bonds
of a Series in the event that any replacement policy or instrument is obtained
for any Bond Insurance, Mortgagor Bankruptcy Fund or Bond, Primary Mortgage
Insurance Policy, Pool Insurance Policy, Special Hazard Insurance Policy or Fund
or surety bond or Letter of Credit with respect to such Series from an Insurer
or other Person other than the Person who issued such policy or instrument;
provided, however, that the Trustee shall not be required to accept any such
replacement policy or instrument unless the Trustee has received from each
Rating Agency rating such Bonds a written instrument to the effect that such
acceptance by the Trustee will not result in the lowering of the then applicable
rating of any Bonds issued pursuant to this Indenture by such Rating Agency.

         (c)      Provided the conditions set forth in paragraph (d) hereof have
been satisfied, in substitution for any Bond Insurance, Mortgagor Bankruptcy
Fund or Bond, Primary Mortgage Insurance Policy, Pool Insurance Policy, Special
Hazard Insurance Policy or Fund, surety bond, letter of credit, and/or other
policy, instrument, or other credit enhancement securing Mortgage Loans pledged
to secure a Series of Bonds, the Depositor may pledge one or more Fannie Mae or
Freddie Mac Certificates representing interests in such Mortgage Loans, provided
the pass-through interest rate on each such Fannie Mae or Freddie Mac
Certificate is not less than the weighted average Net Rate of the Mortgage Loans
in which such Mortgage Certificate represents an interest. For this purpose, the
Net Rate of a Mortgage Loan will equal the per annum interest rate available to
make payments on the Bonds secured by such Mortgage Loan (i.e., such Mortgage
Loan's Note Rate less servicing and credit enhancement costs).

         (d)      To effect any substitution of credit enhancement pursuant to
paragraph (c) above, the Trustee shall transfer the Mortgage Loans to Fannie Mae
or Freddie Mac (subject to the Trustee (or its assignee) being named as the
registered holder of the Fannie Mae or Freddie Mac Certificates to be issued
representing interests in such Mortgage Loans) upon delivery by the Depositor to
the Trustee of the following:

                  (1)      cash or Letter of Credit in an amount equal to the
         aggregate Outstanding Mortgage Loan Amount of the Mortgage Loans being
         transferred to Fannie Mae or Freddie Mac, which may be used to make any
         payments of principal and interest on the Bonds pertaining to such
         Mortgage Loans while the Mortgage Loans are held by Fannie Mae or
         Freddie Mac;

                  (2)      an Depositor Request identifying (i) the Mortgage
         Loans subject to the substitution of credit enhancement and (ii) the
         issue date, maturity, principal balance and pass-through interest rate
         of the Fannie Mae or Freddie Mac Certificates to be issued with respect
         to those Mortgage Loans; and

                  (3)      an Opinion of Counsel to the effect that, upon the
         Trustee's receipt of the Fannie Mae or Freddie Mac Certificates, the
         Trustee will have a first-priority, perfected security interest in the
         Fannie Mae or Freddie Mac Certificates.

         To the extent that the Depositor substitutes Freddie Mac Certificates
for any credit enhancement as provided above, the Depositor will deposit cash
equal to one month's interest on such Freddie Mac Certificates. In addition, the
one month delay and the terms of Freddie Mac's guarantee with respect to Freddie
Mac Certificates shall not be construed as any change in the payment terms with
respect to such Series of Bonds.

Section 9.15.     Notice of Events of Default.

         The Depositor shall give the Trustee and the Rating Agencies prompt
written notice of each Event of Default hereunder, each default on the part of
the Servicer of its obligations under the Servicing Agreement [and each default
on the part of the Mortgage Loan Seller of its obligations under the Mortgage
Loan Sale Agreement.]

Section 9.16.     Investment Company Act.

         The Depositor shall at all times conduct its operations so as not to be
subject to, or shall comply with, the requirements of the Investment Company Act
of 1940, as amended (or any successor statute), and the rules and regulations
thereunder.

Section 9.17.     Treatment of Bonds as Debt for Tax Purposes.

         The Depositor shall treat the Bonds as indebtedness for all federal and
state tax purposes.

                                   ARTICLE TEN

                             SUPPLEMENTAL INDENTURES

Section 10.01.    Supplemental Indentures Without Consent of Bondholders.

         Without the consent of the Holders of any Bonds of any Series, the
Depositor and the Trustee, at any time and from time to time, may enter into one
or more indentures supplemental hereto, in form satisfactory to the Trustee, for
any of the following purposes:

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

         Series that has not theretofore been authorized by a Series Supplement;
         or

                  (4)      to amend any provision of this Indenture in
         connection with the creation of any Series or Class but only with
         respect to a Series or Class that has not theretofore been authorized
         by a Series Supplement and only insofar as any such amendment does not
         adversely affect any Outstanding Series or Class; or

                  (5)      to evidence the succession of another Person to the
         Depositor to the extent permitted herein, and the assumption by any
         such successor of the covenants of the Depositor herein and in the
         Bonds contained; or

                  (6)      to add to the covenants of the Depositor or the
         Trustee, for the benefit of the Holders of all Bonds or the Bonds of
         any Series, or to surrender any right or power herein conferred upon
         the Depositor; or

                  (7)      to convey, transfer, assign, mortgage or pledge any
         property to or with the Trustee; or

                  (8)      to cure any ambiguity, to amend, correct or
         supplement any provision herein or in any supplemental indenture that
         may be defective, ineffective or inconsistent with any other provision
         herein or in any supplemental indenture, or amend any other provisions
         with respect to matters or questions arising under this Indenture;
         provided that such action shall not adversely affect the interests of
         the Holders of the Outstanding Bonds of any Series or Class; or

                  (9)      to evidence and provide for the acceptance of
         appointment hereunder by a successor Trustee with respect to one or
         more Series of Bonds and to add to or change any of the provisions of
         this Indenture as shall be necessary to facilitate the administration
         of the trusts hereunder by more than one Trustee, pursuant to the
         requirements of Section 7.11 or 7.12 hereof; or

                                      -51-
<PAGE>   58

                  (10)     to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the TIA or under any similar
         federal statute hereafter enacted or to conform the provisions of this
         Indenture to the TIA, as amended from time to time, and to add to this
         Indenture such other provisions as may be expressly required by the
         TIA.

         The Trustee is hereby authorized to join in the execution of any such
supplemental indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties, liabilities or immunities under this Indenture or
otherwise except to the extent required by law.

         The Trustee may in its discretion determine whether or not the rights
of the Holder of Bonds of a particular Series would be adversely affected by any
supplemental indenture and any such determination shall be conclusive upon the
Holders of all Bonds, whether theretofore or thereafter authenticated and
delivered hereunder. In making such determination, a supplemental indenture
shall be conclusively deemed by the Trustee not to adversely affect a particular
Series if (i) the Trustee receives a letter or other writing from each Rating
Agency rating the Series to the effect that execution of the supplemental
indenture will not result in any change in the current rating assigned by that
Rating Agency to the Series and (ii) the supplemental indenture effects no
change in principal priority schedules, interest rates, Redemption and Special
Redemption prices, substitution of Mortgage Collateral, Payment Dates, Record
Dates, Accounting Dates, terms of Optional and Special Redemption, the
application of Surplus to the payment of the Series or other payment terms
established by the Series Supplement for the Series. The Trustee shall not be
liable for any such determination made in good faith.

Section 10.02.    Supplemental Indentures With Consent of Bondholders.

         With the consent of the Holders of not less than [66 2/3%] of the
principal balance of the Outstanding Bonds of each Series to be affected, by Act
of said Holders delivered to the Depositor and the Trustee, the Depositor and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to, or changing in any manner or
eliminating any of the provisions of, this Indenture relating to such Series or
of modifying in any manner the rights of the Holders of the Bonds of such Series
under this Indenture; provided, however, that no such supplemental indenture
shall, without the consent of the Holder or Beneficial Owner of each Outstanding
Bond as evidenced by the Bond Register and the records of the Clearing Agency
and Clearing Agency Participants affected thereby:

                  (1)      change the Stated Maturity of the principal of, or
         the timing of any installment of principal or interest on, any Bond,
         reduce the principal amount thereof or the Bond Interest Rate thereon
         or the Redemption Price or time for redemption with respect thereto,
         change the provisions of this Indenture and the related Series
         Supplement relating to the application of proceeds of the Trust Estate
         to the payment of principal of Bonds, change any place where, or the
         coin or currency in which, any Bond or the interest thereon is payable,
         or impair the right to institute suit for the enforcement of any such
         payment on or after the Maturity thereof (or, in the case of
         redemption, on or after the applicable Redemption Date or Special
         Redemption Date); or

                  (2)      reduce the percentage in principal amount of the
         Outstanding Bonds of any Series, the consent of the Holders of which is
         required for the execution of any such supplemental indenture, or the
         consent of the Holders of which is required for any waiver of
         compliance with certain provisions of this Indenture or certain
         Defaults hereunder and their consequences provided for in this
         Indenture; or

                  (3)      impair or adversely affect the Trust Estate for a
         Series except as otherwise permitted herein; or

                  (4)      permit the creation of any lien ranking prior to or
         on a parity with the lien of this Indenture with respect to any part of
         a Trust Estate or terminate the lien of this Indenture on any property
         at any time subject hereto or deprive the Holder of any Bond of the
         security afforded by the lien of this Indenture; or

                                      -52-
<PAGE>   59

                  (5)      change any of the conditions precedent for the
         redemption of any Series of Bonds under this Indenture or any Series
         Supplement; or

                  (6)      modify any of the provisions of this Section 6.14,
         Section 6.15, or Section 6.16, except to increase any such percentage
         or to provide that certain other provisions of this Indenture cannot be
         modified or waived without the consent of the Holder or Beneficial
         Owner of each Outstanding Bond as evidenced by the Bond Register and
         the records of the Clearing Agency and Clearing Agency Participants
         affected thereby.

         The Trustee may in its discretion determine whether or not any Bonds of
a particular Series would be affected by any supplemental indenture, and any
such determination shall be conclusive upon the Holders and Beneficial Owners of
all Bonds of such Series, whether theretofore or thereafter authenticated and
delivered hereunder. The Trustee shall not be liable for any such determination
made in good faith.

         It shall not be necessary for any Act of Bondholders under this Section
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

         Promptly after the execution by the Depositor and the Trustee of any
supplemental indenture pursuant to this Section 10.02, the Depositor shall mail
to the Holders of the Bonds as their names appear on the Bond Register to which
such supplemental indenture relates, a notice setting forth in general terms the
substance of such supplemental indenture. Any failure of the Depositor to mail
such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture.

Section 10.03.    Execution of Supplemental Indentures.

         In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 7.01) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
The Depositor shall cause executed copies of any supplemental indentures to be
delivered to the Rating Agencies.

Section 10.04.    Effect of Supplemental Indenture.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes with respect to
any affected Series; and every Holder of Bonds of any Series theretofore or
thereafter authenticated and delivered hereunder and affected by such
supplemental indenture shall be bound thereby.

Section 10.05.    Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the TIA as then in effect so long as this
Indenture shall then be qualified under the TIA.

Section 10.06.    Reference in Bonds to Supplemental Indentures.

         Bonds authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and if required by the
Trustee shall, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Depositor shall so
determine, new Bonds so modified as to conform, in the opinion of the Trustee

Date.

Section 11.04.    Notice of Redemption by the Depositor.

         Notice of redemption shall be given by the Trustee in the name of and

         such Series are to be paid in full, the fact of such payment in full
         and that interest thereon shall cease to accrue on the date specified
         on the notice;

                  (4)      if such payment is the final payment on such Bond of
         such Series; and

                  (5)      the place where such Bonds of such Series are to be
         surrendered for payment of the Redemption Price if such Bonds of such

         Notice of redemption of Bonds of a Series shall be given by the
Depositor or, at the Depositor's request, by the Trustee in the name and at the
expense of the Depositor. Failure to give notice of redemption, or any defect
therein, to any Holder of any Bond of a Series selected for redemption shall not
impair or affect the validity of the redemption of any other Bond of such
Series.

Section 11.05.    Deposit of Redemption Price for Optional Redemptions.

         In the case of all redemptions, on or before the Business Day next
preceding the giving of notice of redemption as provided in Section 11.04, the
Depositor shall deposit with the Trustee cash, Certificates of Deposit or a
Letter of Credit in an amount sufficient to provide for payment of the
Redemption Price of all of the Bonds of the affected Series that are to be
redeemed on such Redemption Date (unless such payment is to be made from the
Collateral Proceeds Account or the Reserve Fund for such Series).

Section 11.06.    Bonds Payable on Redemption Date.

         Notice of redemption having been given as provided in Section 11.04,
the Bonds of a Series or portions thereof so to be redeemed shall, on the
applicable Redemption Date, become due and payable at the Redemption Price, and
on such Redemption Date (unless the Depositor shall Default in the payment of
the Redemption Price) such Bonds, shall cease to bear interest as specified in
the related Series Supplement. On or after the Redemption Date, such Bonds shall
be paid by the Depositor at the Redemption Price; provided, however, that
payments due on a Payment Date on or prior to the Redemption Date shall be
payable to the Holders of such Bonds registered as such on the relevant Record
Dates according to their terms and the provisions of Section 3.07.

         If any Bond called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid, bear interest from the
Redemption Date at the applicable Bond Interest Rate.

appropriate to enforce such payment or performance, including the institution
and prosecution of appropriate Proceedings. In the event that the Trustee has
not received timely payment on the Mortgage Certificates securing a Series, the
Trustee shall immediately notify GNMA, Fannie Mae, Freddie Mac or other
appropriate Person or such other Persons designated by any of them, as the case
may be, of the failure to receive such payment. The Trustee shall request that
GNMA, Fannie Mae, Freddie Mac or other appropriate Person wire such payments in
immediately available funds to the Trustee, or take such other action as the
Trustee shall designate in accordance with (a) the procedures of GNMA, Fannie
Mae, Freddie Mac or other appropriate Person then in effect and (b) any

related Mortgaged Premises is located, the Security Instrument held by the
Trustee will continue to represent a first lien on the Mortgaged Premises,
notwithstanding the execution of the agreement subordinating such Security
Instrument to the easement; and (iv) the Trustee shall have received an
Officer's Certificate of the Master Servicer of such Mortgage Loan certifying
that the creation of such easement will not materially and adversely affect the

Trustee for deposit to the Collateral Proceeds Account of the lesser of (i) the

remitted to the Trustee by the Master Servicer or a Seller, as the case may be,
in escrow pursuant to the related Servicing Agreement or Sales Agreement, as the
case may be, shall be deposited into the Reserve Fund for the related Series and
shall, together with earnings thereon, (i) be released to the Master Servicer or
a Seller, as the case may be, on receipt by the Trustee of satisfactory evidence
that the Security Instrument Assignment has been recorded in the name of the
Trustee or (ii) be applied by the Trustee to redeem Bonds in the event of a
default in the payment of the principal or interest on the related Mortgage
Loan.

         In order to facilitate the servicing of the Mortgage Loans securing a
Series by the Master Servicer, the Master Servicer may retain the Records in
accordance with the provisions of the Servicing Agreement and applicable
Servicing Agreement for such Series and this Indenture. The Trustee hereby
designates the Master Servicer its agent and bailee to hold the Records pursuant
to the Servicing Agreement and applicable Servicing Agreement. By the
designation pursuant to this Section 12.13 and the acceptance of such
designation pursuant to this Section 12.13 and the acceptance of such
designation by the Master Servicer pursuant to the Servicing Agreement, the
Trustee, as a secured party, has possession of the Records for purposes of
Section 9-305 of the applicable Uniform Commercial Code.

Section 12.14.    Collections on the Mortgage Loans.

         In order to facilitate the servicing of the Mortgage Loans securing a
Series by the Master Servicer of such Mortgage Loans, each Master Servicer of a
Mortgage Loan securing such Series shall retain, in accordance with the
provisions of the applicable Servicing Agreement for such Series and this
Indenture, all collections on such Mortgage Loans prior to the time they are
deposited into the Collateral Proceeds Account for such Series. The Trustee
hereby designates the Master Servicer as its agent and bailee to hold such
collections on such Mortgage Loans until they are deposited into the Collateral
Proceeds Account for such Series. By the designation pursuant to this Section
12.14 and the acceptance of such designation by the Master Servicer pursuant to

Series, enter into or consent to any amendment or supplement to the Servicing
Agreement with respect to such Series for the purpose of increasing the
obligations or duties of any party other than the Trustee or the Bondholders,
provided that such amendment or supplement cannot reasonably be expected to
adversely affect the Holders of Bonds of such Series. Such amendment or
supplement shall be deemed not to adversely affect the Holders of the Bonds of
such Series if there is delivered to the Trustee written notification from each
Rating Agency that rated such Series to the effect that such amendment or
supplement will not result in any change in the current rating assigned by that
Rating Agency to such Series. The Trustee may, in its discretion, decline to
enter into or consent to any such supplement or amendment if its own rights,
duties or immunities shall be adversely affected.

Section 12.16.    Termination and Substitution of Servicing Agreements.

         In the event of an event of default specified in Section 6.01 of the
Servicing Agreement, the Trustee may (or as otherwise provided in the Servicing
Agreement) terminate the Servicer as provided in Section 6.01 and Section 6.02
of the Servicing Agreement. If the Trustee terminates the Servicer, the Trustee
shall pursuant to Section 6.02 of the Servicing Agreement assume the duties of
the Servicer or appoint a successor servicer acceptable to the Issuer and the
Rating Agencies and meeting the requirements set forth in the Servicing
Agreement.

Section 12.17.    Opinion of Counsel.

         The Trustee shall be entitled to receive at least [____ Business Days]
notice of any action to be taken pursuant to Section 12.16 with respect to a
Series, accompanied by copies of any instruments involved, and the Trustee shall
also be entitled to receive an Opinion of Counsel, in form and substance
reasonably satisfactory to the Trustee, stating the legal effect of any such
action, outlining the steps required to complete the same, and concluding that
all conditions precedent to the taking of such action have been complied with.
Counsel rendering any such opinion may rely without independent investigation on
the accuracy and validity of any certificate or other instrument delivered to
the Trustee in connection with any such action.

         (a) On each Payment Date for a Series, if either no Default or Event of
Default shall have occurred and be continuing or a Default or Event of Default
shall have occurred and be continuing but the entire unpaid principal amount of
the Bonds of such Series shall not have been declared due and payable pursuant
to Section 6.02, then on such Payment Date, the Trustee shall withdraw funds

Price as provided in Article Eleven.

         (c) On each Payment Date, the Trustee shall withdraw any excess funds

Monthly Remittance Report, (ii) specifying the procedures they have applied to
the data and the computations used in preparing that Monthly Remittance Report
and to the information received from the Trustee, (iii) indicating, based on
such procedures, the amount they have recalculated as the Aggregate Collateral

upon such procedures, nothing has come to their attention that leads them to
believe that the calculations within the Monthly Remittance Report have not been
performed in accordance with the provisions of this Indenture and the related
Series Supplement.

         If a Yearly Accountants' Certificate delivered pursuant to Section
13.01(d) indicates that any correction should be made in the preparation of

and reflected in succeeding Reports.

Section 13.02.    [Reserved].

Section 13.03.    Disbursement of Monies Out of Custodial Reserve Fund.

         If any Monthly Remittance Report for a Series received by the Trustee

and timely pay the premiums due on the applicable Insurance Policy or the
amounts due to the Master Servicer as specified in such Monthly Remittance

Aggregate Collateral Value of the Mortgage Collateral over the principal balance
of the Bonds of such Series then Outstanding.

         The Depositor may deliver to the Trustee written instructions with
respect to identified Mortgage Collateral executed by the Depositor and another
Person to the effect that, following notice from the other Person, excess funds
attributable to the identified Collateral are to be disbursed to the other
Person and not to the Depositor. Such instructions may be irrevocable except
upon receipt by the Trustee of a written revocation executed by the other
Person. On receipt of notice from the other Person requesting that such excess
funds be delivered to the other Person, the Trustee shall so disburse such
excess funds rather than releasing those funds to the Depositor.

         Notwithstanding any other provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Bondholders in regard to proof of the holding of Bonds and of the appointment of
proxies, and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting.
Except as otherwise permitted or required by any such regulations, the holding
of Bonds shall be proved in the manner specified in Section 15.03, and the
appointment of any proxy shall be proved in the manner specified in said Section
15.03; provided, however, that such regulations may provide that written
instruments appointing proxies regular on their face may be presumed valid and
genuine without the proof hereinabove or in said Section 15.03 specified.

         The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Depositor or by Bondholders as provided in Section 14.03, in which case the
Depositor or the Bondholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by vote of the Holders of a majority
in principal amount of the Bonds represented at the meeting.

         At any meeting each Holder of Bonds of any Series or any proxy shall be
entitled to one vote for each [$1,000] in initial principal amount of
Outstanding Bonds held or represented by him; provided, however, that no vote
shall be cast or counted at any meeting in respect of the principal amount of
any Bond challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote
other than by virtue of Bonds held by him or by virtue of instruments in writing

         At any meeting of Bondholders of any or all Series, the presence of
Persons holding or representing Outstanding Bonds of the applicable Series in an
aggregate principal balance sufficient to take action on the business for the
transaction of which such meeting was called shall constitute a quorum, but, if
less than a quorum is present, the Persons holding or representing a majority in
aggregate principal balance of the Bonds of the applicable Series represented at
the meeting may adjourn such meeting with the same effect, for all intents and
purposes, as though a quorum had been present, and the meeting may be held as so
adjourned without further notice.

authorize or permit, by reason of any call of a meeting of Bondholders or any
rights expressly or impliedly conferred hereunder to make such call, any
hindrance or delay in the exercise of any right or rights conferred upon or
reserved to the Trustee or to the Bondholders under any of the provisions of

                                  MISCELLANEOUS

Section 15.01.    Compliance Certificates and Opinions.

         Upon any application or request by the Depositor to the Trustee to take
any action under any provision of this Indenture, the Depositor shall furnish to
the Trustee an Officer's Certificate stating that all conditions precedent, if
any, provided for in this Indenture relating to the proposed action have been
complied with and an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent, if any, have been complied with, except
that in the case of any such application or request as to which the furnishing
of such documents is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate or
opinion need be furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture, including one furnished
pursuant to specific requirements of this Indenture relating to a particular
application or request (other than certificates provided pursuant to TIA Section
324(a)(4)) shall include and shall be deemed to include (regardless of whether
specifically stated therein) the following:

                  (1)      a statement that each individual signing such
         certificate, opinion, or letter has read such covenant or condition and
         the definitions herein relating thereto;

                  (2)      a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (4)      a statement whether, in the opinion of each such
         individual, such condition or covenant has been complied with.

Section 15.02.    Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of an Officer of the Depositor may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such Officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an Officer or Officers of the Depositor, stating that the
information with respect to such factual matters is in the possession of the
Depositor, unless such counsel knows that the certificate or opinion or
representations with respect to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

Section 15.03.    Acts of Bondholders.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Bondholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Bondholders in person or by agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Trustee, and, where it is hereby expressly required, to the
Depositor. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the
Bondholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and conclusive in favor of the Trustee and the
Depositor, if made in the manner provided in this Section.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any manner that the Trustee deems
sufficient.

         (c) The ownership of Bonds shall be proved by the Bond Register.

         (d) The beneficial ownership of Book-Entry Bonds shall be proved by the
books of the Clearing Agency or Clearing Agency Participant.

         (e) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Bonds shall bind the Holder (and any
transferee thereof) of every Bond issued upon the registration thereof or in
exchange therefor or in lieu thereof, in respect of anything done, omitted or
suffered to be done by the Trustee or the Depositor in reliance thereon, whether
or not notation of such action is made upon such Bond.

Section 15.04.    Notices, Etc., to Trustee and Depositor.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Bondholders or other documents provided for or permitted by this
Indenture to be made upon, given or furnished to, or filed with:

                  (1)      the Trustee by any Bondholder or by the Depositor
         shall be sufficient for every purpose hereunder if made, given,
         furnished or filed in writing to or with the Trustee at its Corporate
         Trust Office; or

                                      -66-
<PAGE>   73

                  (2)      the Depositor by the Trustee or by any Bondholder
         shall be sufficient for every purpose hereunder (except as provided in
         the Series Supplement for a Series) if in writing and mailed,
         first-class postage prepaid, to the Depositor addressed to it at 7130
         Goodlett Farms Parkway, Cordova, Tennessee 38018, Attention: President,
         or at any other address previously furnished in writing to the Trustee
         by the Depositor.

Section 15.05.    Notices to Bondholders; Waiver.

         Where this Indenture provides for notice to Bondholders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each
Bondholder affected by such event at his address as it appears on the Bond
Register not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to
Bondholders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Bondholder shall affect the
sufficiency of such notice with respect to other Bondholders, and any notice
that is mailed in the manner herein provided shall conclusively be presumed to
have been duly given.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Bondholders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

         In the event that, by reason of the suspension of regular mail service
as a result of a strike, work stoppage or similar activity, it shall be
impractical to mail notice of any event to Bondholders when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice that is satisfactory to the Trustee shall be deemed
to be a sufficient giving of such notice.

Section 15.06.    Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with another
provision hereof that is required to be included in this Indenture by any of the
provisions of the TIA, such required provision shall control.

Section 15.07.    Effect of Headings and Table of Contents.

         The Article and Section headings and the Table of Contents herein are
for convenience only and shall not affect the construction hereof.

Section 15.08.    Successors and Assigns.

         All covenants and agreements in this Indenture by the Depositor shall
bind its successors and assigns, whether so expressed or not.

Section 15.09.    Separability.

         In case any provision in this Indenture or in the Bonds shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 15.10.    Benefits of Indenture.

         Nothing in this Indenture or in the Bonds, express or implied, shall
give to any Person, other than the parties hereto, and their successors
hereunder, any separate trustee or co-trustee appointed under Section 7.10 and
the Bondholders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

Section 15.11.    Legal Holidays.

         In the event that the date of any Payment Date shall not be a Business
Day, then notwithstanding any other provision of the Bonds or this Indenture,
payment need not be made on such date but may be made on the next succeeding
Business Day with the same force and effect as if made on the nominal date of
any such Payment Date,

                                      -67-
<PAGE>   74

and no interest shall accrue for the period from and after any such nominal date
provided such payment is made in full on such next succeeding Business Day.

Section 15.12.    Governing Law.

         IN VIEW OF THE FACT THAT BONDHOLDERS ARE EXPECTED TO RESIDE IN MANY
STATES AND OUTSIDE THE UNITED STATES AND THE DESIRE TO ESTABLISH WITH CERTAINTY
THAT THIS INDENTURE WILL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH THE LAW OF A STATE HAVING A WELL-DEVELOPED BODY OF COMMERCIAL
AND FINANCIAL LAW RELEVANT TO TRANSACTIONS OF THE TYPE CONTEMPLATED HEREIN, THIS
INDENTURE AND EACH BOND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF [NEW YORK] APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED THEREIN.

Section 15.13.    Counterparts.

         This instrument may be executed in any number of counterparts, each of
