an interest, other than the Excepted Assets and (h) all proceeds with respect to
the foregoing clauses (a) through (g). The collateral described in the foregoing

made, however, in trust, to secure the Notes and each Hedge Agreement, subject
to the Priority of Payments, equally and ratably without prejudice, priority or
distinction between any Note and any other Note by reason of difference in time
of issuance or otherwise, except as expressly provided in this Indenture, and to

shall, for the purpose of determining the property subject to the lien of this

Coverage Tests or compliance by the Issuer with any of the other provisions
hereof), be deemed to include any securities and any investments granted by or
on behalf of the Issuer to the Trustee for the benefit of the Secured Parties,
whether or not such securities or such investments satisfy the criteria set
forth in the definitions of "Collateral Debt Security" or "Eligible Investment,"
as the case may be.

          Except to the extent otherwise provided in this Indenture, this
Indenture shall constitute a security agreement under the laws of the State of
New York applicable to agreements made and to be performed therein, for the
benefit of the Noteholders and each Hedge Counterparty. Upon the occurrence and
during the continuation of any Event of Default hereunder, and in addition to
any other rights available under this Indenture or any other Assets held for the
benefit and security of the Noteholders and each Hedge Counterparty or otherwise
available at law or in equity but subject to the terms hereof, the Trustee shall
have all rights and remedies of a secured party on default under the laws of the
State of New York and other applicable law to enforce the assignments and
security interests contained herein and, in addition, shall have the right,
subject to compliance with any mandatory requirements of applicable law and the
terms of this Indenture, to sell or apply any rights and other interests
assigned or pledged hereby in accordance with the terms hereof at public and
private sale.

          The Trustee acknowledges such Grants, accepts the trusts hereunder in
accordance with the provisions hereof, and agrees to perform the duties herein
in accordance with, and subject to, the terms hereof, in order that the
interests of the Secured Parties may be adequately and effectively protected in

          provisions of its organizational documents have not been amended

          such amendment), will be deemed a "special purpose entity" meeting
          S&P's then-published criteria for bankruptcy-remote special purpose

          purchase such Preferred Equity Security on the date when such
          redemption or purchase is required pursuant to the terms of the

          of such redemption or purchase date that the issuer or affiliate of

          did elect under the terms of the agreement setting forth the rights of
          the holder of that Preferred Equity Security), if the Collateral
          Manager, on behalf of the Issuer, (subject to the applicable
          provisions of the Servicing Agreement) consents to extend such
          redemption or purchase date; provided that such consent does not
          extend the redemption or purchase date by more than two (2) years
          after the redemption or purchase date required under such agreement
          (that is, the original redemption or purchase date under such
          agreement as extended by all extensions of such date that the issuer
          or affiliate of the issuer of the Preferred Equity Security had the
          right to elect and did elect under the terms of such agreement) and
          the amount required to be paid in connection with such redemption or
          purchase is paid on or before such extended redemption or purchase
          date, or (2) with respect to which there is known to the Issuer or the
          Collateral Manager a default (other than any payment default) which
          default entitles the holders thereof to accelerate the maturity of all
          or a portion of the principal amount of such obligation; provided,
          however, that, in each case, if such default is cured or waived then
          such asset shall no longer be a Defaulted Security or (3) with respect
          to which it is known to the Collateral Manager that (A) any
          bankruptcy, insolvency or receivership proceeding has been initiated
          in connection with the issuer of such Preferred Equity Security, or
          (B) there has been proposed or effected any distressed exchange or
          other debt restructuring where the issuer of such Preferred Equity
          Security has offered the debt holders a new security or package of
          securities that either (x) amounts to a diminished financial
          obligation or (y) has the purpose of helping the issuer to avoid
          default, or (4) that has been rated "CC," "D" or "SD" or below by S&P

          Manager that the issuer of such Preferred Equity Security is in
          default (without giving effect to any applicable grace period or
          waiver) as to payment of principal and/or interest on another
          obligation (and such default has not been cured or waived) which is
          senior or pari passu in right of payment to such Preferred Equity
          Security, except that a Preferred Equity Security will not constitute
          a "Defaulted Security" under this clause (5) if each of the Rating
          Agencies has confirmed in writing that such event shall not result in
          the reduction, qualification or withdrawal of any rating of the Notes;

                    (ii) with respect to a Loan (other than a Single Asset
          Mortgage Security, a Single Borrower Mortgage Security or a Rake
          Bond), if a foreclosure or default (whether or not declared) with
          respect to the related commercial mortgage loan has occurred;
          provided, however, that notwithstanding the foregoing, a Loan shall
          not be deemed to be a Defaulted Security as a result of (1) the
          related borrower's failure to pay interest on such Loan or on the
          related commercial mortgage loan on the initial due date therefor, if
          the related lender or holder of such Loan or of the related commercial
          mortgage loan consents to extend the due date when such interest is
          due and payable, and such interest is paid on or before such extended
          due date (provided that such interest is paid not more than 60 days
          (or 30 days if such interest was previously paid 60 days after the
          initial date that it was due) as a result of the Collateral Manager,
          on behalf of


                                      -32-

<PAGE>

          the Issuer, (subject to the applicable provisions of the Servicing
          Agreement) previously consenting to extend such due date after the
          initial date that it was due) after the initial date that it was due),
          or (2) the related borrower's failure to pay principal on such Loan or
          the related commercial mortgage loan on the original maturity date
          thereof (as defined below), if the related lender or holder of such
          Loan or of the related commercial mortgage loan consents to extend
          such maturity date (so long as the Maturity Extension Requirements are
          met) and such principal is paid on or before such extended maturity
          date, or (3) the occurrence of any default other than a payment
          default with respect to such Loan or the related commercial mortgage
          loan, unless and until the earlier of (A) the declaration of default
          and acceleration of the maturity of the Loan by the lender or holder
          thereof and (B) the continuance of such default uncured for 60 days
          after such default became known to the Collateral Manager or the
          Servicer or, subject to the satisfaction of the Rating Agency
          Condition and, so long as MBIA is deemed to be the Controlling Class
          hereunder, the consent of MBIA, such longer period as the Collateral
          Manager (subject to the applicable provisions of the Servicing
          Agreement) determines. As used above, the term "original maturity
          date" means the maturity date of a Loan or the related commercial
          mortgage loan as extended by all extensions thereof which the related
          borrower had the right to elect and did elect under the terms of the
          instruments and agreements relating to such Loan or to the related
          commercial mortgage loan, but before taking into account any
          additional extensions thereof that are consented to by the lender or
          holder of such Loan or of the related commercial mortgage loan; and

                    (iii) with respect to a CMBS Security, a CRE CDO Security, a
          REIT Debt Security, a Single Asset Mortgage Security, a Single
          Borrower Mortgage Security or a Rake Bond (1) as to which there has
          occurred and is continuing a principal payment default (without giving
          effect to any applicable grace period or waiver) or (2) as to which
          there is known to the Collateral Manager a default (other than any
          payment default) which default entitles the holders thereof to
          accelerate the maturity of all or a portion of the principal amount of
          such obligation; provided, however, that, in each case, if such
          default is cured or waived then such asset shall no longer be a
          Defaulted Security, or (3) as to which it is known to the Collateral
          Manager that (A) any bankruptcy, insolvency or receivership proceeding
          has been initiated in connection with the issuer of such security, or
          (B) there has been proposed or effected any distressed exchange or
          other debt re-structuring where the issuer of such security has
          offered the debt holders a new security or package of securities that
          either (x) amounts to a diminished financial obligation or (y) has the
          purpose of helping the issuer to avoid default, or (4) that has been
          rated "CC," "D" or "SD" or below by S&P, "CC" or below by Fitch, or
          "Ca" or "C" by Moody's, or with respect to REIT Debt Securities, the
          issuer of which has a credit rating of "D" or "SD" or as to which S&P
          has withdrawn its rating, or (5) as to which it is known to the
          Collateral Manager that the issuer thereof is in default (without
          giving effect to any applicable grace period or waiver) as to payment
          of principal and/or interest on another obligation (and such default
          has not been cured or waived) which is senior or pari passu in right
          of payment to such security, except that any such


                                      -33-

<PAGE>

          security will not constitute a "Defaulted Security" under this clause
          (5) if each of the Rating Agencies has confirmed in writing that such
          event shall not result in the reduction, qualification or withdrawal
          of any rating of the Notes, or (6)(A) as to which there has been a
          failure to pay interest in whole or in part for the lesser of (x) six
          months or (y) three payment periods (if such security is rated (or
          privately rated for purposes of the issuance of the Securities) below
          "Baa3" by Moody's or "BBB-" by S&P or Fitch); provided, however, that
          if the Rating Agency Condition for such security is satisfied with
          respect to S&P and Moody's and, so long as MBIA is deemed to be the
          Controlling Class hereunder, MBIA has consented, the Collateral
          Manager may choose not to treat such security as a Defaulted Security
          or (B) as to which there has been a failure to pay interest in whole
          or in part for the lesser of (x) one year or (y) six consecutive
          payment periods (if such security is rated (or privately rated for
          purposes of the issuance of the Securities) "BBB-" or higher by S&P or
          Fitch, or "Baa3" or higher by Moody's) even if by its terms it
          provides for the deferral and capitalization of interest thereon;

provided that any Collateral Debt Security which has sustained a write-down of
Principal Balance in accordance with its terms will not necessarily be
considered a Defaulted Security solely due to such writedown; provided, further,
that, for purposes of calculating the Par Value Ratios, any Collateral Debt
Security that has sustained an implied reduction of principal balance due to an
appraisal reduction will not necessarily be considered a Defaulted Security
solely due to such implied reduction.

For purposes of calculating the Par Value Ratios, an appraisal reduction of a
Collateral Debt Security will be assumed to result in an implied reduction of
principal balance for such Collateral Debt Security only if such appraisal
reduction is intended to reduce the interest payable on such Collateral Debt
Security and only in proportion to such interest reduction. The Collateral
Manager shall notify the Trustee of any appraisal reductions of Collateral Debt
Securities if the Collateral Manager has actual knowledge thereof.

For purposes of the definition of "Defaulted Security," the "Maturity Extension
Requirements" will be satisfied with respect to any extension if the maturity
date is extended (i) in the case of Loans other than ARD Loans, to a new
maturity date that is (A) not more than two years after the original maturity
date and (B) not less than ten years prior to the Stated Maturity and (ii) in
the case of ARD Loans, such that (A) the anticipated repayment date will not be
less than 20 years prior to the Stated Maturity and (B) the new maturity date is
not less than three years prior to the Stated Maturity; provided, however, that
notwithstanding the requirements in the foregoing clauses (i) and (ii),

          Section 1.2 Assumptions as to Pledged Obligations.

          (a) In connection with all calculations required to be made pursuant
to this Indenture with respect to Scheduled Distributions on any Pledged
Obligation, or any payments on any other assets included in the Assets, and with
respect to the income that can be earned on Scheduled Distributions on such
Pledged Obligations and on any other amounts that may be received for deposit in
the applicable Collection Account, the provisions set forth in this Section 1.2
shall be applied.

          (b) All calculations with respect to Scheduled Distributions on the
Pledged Obligations securing the Notes shall be made on the basis of information
as to the terms of each such Pledged Obligation and upon report of payments, if
any, received on such Pledged Obligation that are furnished by or on behalf of
the issuer of such Pledged Obligation and, to the extent they are not manifestly
in error, such information or report may be conclusively relied upon in making
such calculations.

          (c) For each Due Period, the Scheduled Distribution on any Pledged
Obligation (other than a Defaulted Security, which, except as otherwise provided
herein, shall be assumed to have a Scheduled Distribution of zero) shall be the
sum of (i) the total amount of payments and collections in respect of such
Pledged Obligation (including all Sales Proceeds received during the Due Period
and not reinvested in Substitute Collateral Debt Securities or retained in the
Principal Collection Account for subsequent reinvestment) that, if paid as
scheduled, will be available in the Collection Accounts at the end of such Due
Period for payment on the Notes and of expenses of the Issuer and the Co-Issuer
pursuant to the Priority of Payments and (ii) any such amounts received in prior
Due Periods that were not disbursed on a previous Payment Date and do not
constitute amounts which have been used as reimbursement with respect to a prior
Interest Advance pursuant to the terms of this Indenture.


                                      -91-

<PAGE>

          (d) With respect to any Collateral Debt Security as to which any
interest or other payment thereon is subject to withholding tax of any relevant
jurisdiction, each Scheduled Distribution thereon shall, for purposes of the
Coverage Tests and the Collateral Quality Tests, be deemed to be payable net of
such withholding tax unless the issuer thereof or obligor thereon is required to
make additional payments to fully compensate the Issuer for such withholding
taxes (including in respect of any such additional payments). On any date of
determination, the amount of any Scheduled Distribution due on any future date
shall be assumed to be made net of any such uncompensated withholding tax based
upon withholding tax rates in effect on such date of determination.

          (e) For purposes of calculating any Interest Coverage Ratio, the
expected interest income on floating rate Collateral Debt Securities and
Eligible Investments and under each Hedge Agreement and the expected interest
payable on the Notes shall be calculated using (i) the interest rates applicable
thereto on the applicable Measurement Date and (ii) accrued original issue
discount on Eligible Investments shall be deemed to be Scheduled Distributions
of interest due on the date such original issue discount is scheduled to be
paid. Notwithstanding the foregoing, for the purposes of calculating any
Interest Coverage Ratio, there shall be excluded all scheduled or deferred
payments of interest on or principal of Collateral Debt Securities and any
payment, including any amount payable to the Issuer by each Hedge Counterparty,
which the Collateral Manager has determined in its reasonable judgment shall not
be made in Cash or received when due.

          (f) Each Scheduled Distribution receivable with respect to a Pledged
Obligation shall be assumed to be received on the applicable Due Date, and each
such Scheduled Distribution shall be assumed to be immediately deposited in the
applicable Collection Account except to the extent the Collateral Manager has a
reasonable expectation that such Scheduled Distribution will not be received on
the applicable Due Date. All such funds shall be assumed to continue to earn
interest until the date on which they are required to be available in the
applicable Collection Account for transfer to the Payment Account for
application, in accordance with the terms hereof, to payments of principal of or
interest on the Notes and, in the case of the Class A-1AR Notes, the Class A-1AR
Commitment Fee or other amounts payable pursuant to this Indenture.

          (g) All calculations required to be made and all reports which are to
be prepared pursuant to this Indenture with respect to the Pledged Obligations,
shall be made on the basis of the date on which the Issuer makes a binding
commitment to purchase or sell an asset (the "trade date"), not the settlement
date.

          (h) For purposes of calculating the Par Value Ratio, an appraisal
reduction of a Collateral Debt Security will be assumed to result in an implied
reduction of Principal Balance for such Collateral Debt Security only if such
appraisal reduction is intended to reduce the interest payable on such
Collateral Debt Security and only in proportion to such interest reduction. For
purposes of the Par Value Ratio, any Collateral Debt Security that has sustained
an implied reduction of Principal Balance due to an appraisal reduction will not
be considered a Defaulted Security solely due to such implied reduction. The
Collateral Manager will notify the Trustee of any appraisal reductions of
Collateral Debt Securities if the Collateral Manager has actual knowledge
thereof.

related Interest Accrual Period divided by 360.

          Section 1.4 Rounding Convention.

          Unless otherwise specified herein, test calculations that evaluate to
a percentage will be rounded to the nearest ten thousandth of a percentage point
and test calculations that evaluate to a number or decimal will be rounded to
the nearest one hundredth of a percentage point.

     increased or decreased by adjustments made on the records of the Trustee or
     the Depository or its nominee, as the case may be, as hereinafter provided.

          (ii) The Notes (other than the Class A-1AR Notes) initially sold in
     offshore transactions in reliance on Regulation S shall be represented by
     one or more permanent global notes in definitive, fully registered form
     without interest coupons with the applicable legend set forth in Exhibits
     A-1, A-2, B, C, D, E, F, G and H, hereto added to the form of such Notes
     (each, a "Regulation S Global Security"), which shall be deposited on
     behalf of the subscribers for such Notes represented thereby with the
     Trustee as custodian for the Depository and registered in the name of a
     nominee of the Depository for the respective accounts of Euroclear and
     Clearstream, Luxembourg or their respective depositories, duly executed by
     the Issuer and the Co-Issuer and authenticated by the Trustee as
     hereinafter provided. The aggregate principal amount of the Regulation S
     Global Securities may from time to time be increased or decreased by
     adjustments made on the records of the Trustee or the Depository or its
     nominee, as the case may be, as hereinafter provided.

          (iii) Definitive Class A-1AR Notes. The Class A-1AR Notes initially
     offered and sold (A) in the United States to (or to U.S. Persons who are)
     QIBs and (B) in offshore transactions in reliance on Regulation S shall be
     issued only in definitive, fully registered, certificated form without
     interest coupons with the applicable legend set forth in Exhibit A-3 hereto
     added to the form of such Notes (each, a "Definitive Class A-1AR Note")
     registered in the name of the beneficial owner thereof unless otherwise
     authorized by the Issuer on the date of issuance. The Class A-1AR Notes
     will not be eligible for clearance and settlement through the facilities of
     the Depository, Euroclear or Clearstream, Luxembourg.

          (c) Book-Entry Provisions. This Section 2.2(c) shall apply only to
Global Securities deposited with or on behalf of the Depository.

          Each of the Issuer and Co-Issuer shall execute and the Trustee shall,
in accordance with this Section 2.2(c), authenticate and deliver initially one
or more Global Securities that shall be (i) registered in the name of the
nominee of the Depository for such Global Security or Global Securities and (ii)
delivered by the Trustee to such Depository or pursuant to such Depository's
instructions or held by the Trustee's agent as custodian for the Depository.

          Agent Members shall have no rights under this Indenture with respect
to any Global Security held on their behalf by the Trustee, as custodian for the
Depository or under the Global Security, and the Depository may be treated by
the Issuer, the Co-Issuer, the Trustee, and any agent of the Issuer, the
Co-Issuer or the Trustee as the absolute owner of such Global Security for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Issuer, the Co-Issuer, the Trustee, or any agent of the Issuer, the
Co-Issuer or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by the Depository or impair, as between the
Depository and its Agent Members, the operation of customary practices governing
the exercise of the rights of a Holder of any Global Security.

          (b) The Notes shall be issuable in minimum denominations of $500,000
and integral multiples of $500 in excess thereof (plus any residual amount).

          Section 2.4 Execution, Authentication, Delivery and Dating.

          The Notes shall be executed on behalf of the Issuer and the Co-Issuer
by an Authorized Officer of the Issuer and the Co-Issuer, respectively. The
signature of such Authorized Officers on the Notes may be manual or facsimile.


                                      -95-

<PAGE>

          Notes bearing the manual or facsimile signatures of individuals who
were at any time the Authorized Officers of the Issuer or the Co-Issuer shall
bind the Issuer or the Co-Issuer, as the case may be, notwithstanding the fact
that such individuals or any of them have ceased to hold such offices prior to
the authentication and delivery of such Notes or did not hold such offices at
the date of issuance of such Notes.

          At any time and from time to time after the execution and delivery of
this Indenture, the Issuer and the Co-Issuer may deliver Notes executed by the
Issuer and the Co-Issuer to the Trustee or the Authenticating Agent for
authentication and the Trustee or the Authenticating Agent, upon Issuer Order,
shall authenticate and deliver such Notes as provided in this Indenture and not
otherwise.

          Each Note authenticated and delivered by the Trustee or the
Authenticating Agent upon Issuer Order on the Closing Date shall be dated as of
the Closing Date. All other Notes that are authenticated after the Closing Date
for any other purpose under this Indenture shall be dated the date of their
authentication.

          Notes issued upon transfer, exchange or replacement of other Notes
shall be issued in authorized denominations reflecting the original aggregate
principal amount of the Notes so transferred, exchanged or replaced, but shall
represent only the current outstanding principal amount of the Notes so
transferred, exchanged or replaced. In the event that any Note is divided into
more than one Note in accordance with this Article 2, the original principal
amount of such Note shall be proportionately divided among the Notes delivered
in exchange therefor and shall be deemed to be the original aggregate principal
amount of such subsequently issued Notes.

          No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note a
Certificate of Authentication, substantially in the form provided for herein,
executed by the Trustee or by the Authenticating Agent by the manual signature
of one of their Authorized Officers, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

          Section 2.5 Registration, Registration of Transfer and Exchange.

          (a) The Issuer and the Co-Issuer shall cause to be kept a register
(the "Notes Register") in which, subject to such reasonable regulations as it
may prescribe, the Issuer and the Co-Issuer shall provide for the registration
of Notes and the registration of transfers and exchanges of Notes. The Trustee
is hereby initially appointed "Notes Registrar" for the purpose of registering
Notes and transfers and exchanges of such Notes with respect to the Notes
Register kept in the United States as herein provided. Upon any resignation or
removal of the Notes Registrar, the Issuer and the Co-Issuer shall promptly
appoint a successor or, in the absence of such appointment, assume the duties of
Notes Registrar.

          If a Person other than the Trustee is appointed by the Issuer and the
Co-Issuer as Notes Registrar, the Issuer and the Co-Issuer shall give the
Trustee prompt written notice of the appointment of a successor Notes Registrar
and of the location, and any change in the location,


                                      -96-

<PAGE>

of the Notes Register, and the Trustee shall have the right to inspect the Notes
Register at all reasonable times and to obtain copies thereof and the Trustee
shall have the right to rely upon a certificate executed on behalf of the Notes
Registrar by an Officer thereof as to the names and addresses of the Holders of
the Notes and the principal amounts and numbers of such Notes.

          Subject to this Section 2.5, upon surrender for registration of
transfer of any Notes at the office or agency of the Issuer to be maintained as
provided in Section 7.2, the Issuer and the Co-Issuer shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denomination and of a
like aggregate principal amount.

          At the option of the Holder, Notes may be exchanged for Notes of like
terms, in any authorized denominations and of like aggregate principal amount,
upon surrender of the Notes to be exchanged at the office or agency of the
Issuer to be maintained as provided in Section 7.2. Whenever any Note is
surrendered for exchange, the Issuer and the Co-Issuer shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Noteholder making the
exchange is entitled to receive.

          All Notes issued and authenticated upon any registration of transfer
or exchange of Notes shall be the valid obligations of the Issuer and the
Co-Issuer, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Notes surrendered upon such registration of transfer or
exchange.

          Every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Issuer and the Notes Registrar duly
executed by the Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made to a Holder for any registration of
transfer or exchange of Notes, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

          None of the Notes Registrar, the Issuer or the Co-Issuer shall be
required (i) to issue, register the transfer of or exchange any Note during a
period beginning at the opening of business 15 days before any selection of
Notes to be redeemed and ending at the close of business on the day of the
mailing of the relevant notice of redemption, or (ii) to register the transfer
of or exchange any Note so selected for redemption.

          (b) No Note may be sold or transferred (including, without limitation,
by pledge or hypothecation) unless such sale or transfer is exempt from the
registration requirements of the Securities Act and is exempt from the
registration requirements under applicable state securities laws.

          (c) No Note may be offered, sold, resold or delivered, within the
United States or to, or for the benefit of, U.S. Persons except in accordance
with Section 2.5(e) below and in accordance with Rule 144A to QIBs who are
Qualified Purchasers purchasing for their own account or for the accounts of one
or more QIBs who are Qualified Purchasers, for which the purchaser is acting as
fiduciary or agent. The Notes may be offered, sold, resold or


                                      -97-

<PAGE>

delivered, as the case may be, in offshore transactions to non-U.S. Persons in
reliance on Regulation S. None of the Issuer, the Co-Issuer, the Trustee or any
other Person may register the Notes under the Securities Act or any state
securities laws.

          (d) Upon final payment due on the Stated Maturity of a Note, the
Holder thereof shall present and surrender such Note at the Corporate Trust
Office of the Trustee or at the office of the Paying Agent (outside the United
States if then required by applicable law in the case of a Note in definitive
form issued in exchange for a beneficial interest in a Regulation S Global
Security pursuant to Section 2.10).

          (e) Transfers of Global Securities. Notwithstanding any provision to
the contrary herein, so long as a Global Security remains outstanding and is
held by or on behalf of the Depository, transfers of a Global Security, in whole
or in part, shall be made only in accordance with Section 2.2(c) and this
Section 2.5(e).

          (i) Subject to clauses (ii) through (iv) of this Section 2.5(e),
     transfers of a Global Security shall be limited to transfers of such Global
     Security in whole, but not in part, to nominees of the Depository or to a
     successor of the Depository or such successor's nominee.

          (ii) Regulation S Global Security to Rule 144A Global Security. If a
     holder of a beneficial interest in a Regulation S Global Security wishes to
     transfer all or a part of its interest in such Regulation S Global Security
     to a Person who wishes to take delivery thereof in the form of a Rule 144A
     Global Security, such holder may, subject to the terms hereof and the rules
     and procedures of Euroclear, Clearstream, Luxembourg or the Depository, as
     the case may be, exchange or cause the exchange of such interest for an
     equivalent beneficial interest in a Rule 144A Global Security of the same
     Class. Upon receipt by the Trustee, as Notes Registrar, of (A) instructions
     from Euroclear, Clearstream, Luxembourg or the Depository, as the case may
     be, directing the Trustee, as Notes Registrar, to cause such Rule 144A
     Global Security to be increased by an amount equal to such beneficial
     interest in such Regulation S Global Security but not less than the minimum
     denomination applicable to the related Class of Notes, and (B) a
     certificate substantially in the form of Exhibit J hereto given by the
     prospective transferee of such beneficial interest and stating, among other
     things, that such transferee acquiring such interest in a Rule 144A Global
     Security is a QIB and a Qualified Purchaser, is obtaining such beneficial
     interest in a transaction pursuant to Rule 144A and in accordance with any
     applicable securities laws of any state of the United States or any other
     applicable jurisdiction, then Euroclear, Clearstream, Luxembourg or the
     Trustee, as Notes Registrar, as the case may be, shall approve the
     instruction at the Depository to reduce such Regulation S Global Security
     by the aggregate principal amount of the interest in such Regulation S
     Global Security to be transferred and increase the Rule 144A Global
     Security specified in such instructions by an Aggregate Outstanding Amount
     equal to such reduction in such principal amount of the Regulation S Global
     Security.

          (iii) Rule 144A Global Security to Regulation S Global Security. If a
     holder of a beneficial interest in a Rule 144A Global Security wishes to
     transfer all or a part of its interest in such Rule 144A Global Security to
     a Person who wishes to take delivery


                                      -98-

<PAGE>

     thereof in the form of a Regulation S Global Security, such holder may,
     subject to the terms hereof and the rules and procedures of Euroclear,
     Clearstream, Luxembourg or the Depository, as the case may be, exchange or
     cause the exchange of such interest for an equivalent beneficial interest
     in a Regulation S Global Security of the same Class. Upon receipt by the
     Trustee, as Notes Registrar, of (A) instructions from Euroclear,
     Clearstream, Luxembourg or the Depository, as the case may be, directing
     the Trustee, as Notes Registrar, to cause such Regulation S Global Security
     to be increased by an amount equal to the beneficial interest in such Rule
     144A Global Security but not less than the minimum denomination applicable
     to the related Class of Notes to be exchanged, and (B) a certificate
     substantially in the form of Exhibit I hereto given by the prospective
     transferee of such beneficial interest and stating, among other things,
     that such transferee acquiring such interest in a Regulation S Global
     Security is a not a U.S. Person and that such transfer is being made
     pursuant to Rule 903 or 904 under Regulation S, then Euroclear,
     Clearstream, Luxembourg or the Trustee, as Notes Registrar, as the case may
     be, shall approve the instruction at the Depository to reduce such Rule
     144A Global Security by the aggregate principal amount of the interest in
     such Rule 144A Global Security to be transferred and increase the
     Regulation S Global Security specified in such instructions by an Aggregate
     Outstanding Amount equal to such reduction in the principal amount of the
     Rule 144A Global Security.

          (iv) Other Exchanges. In the event that, pursuant to Section 2.10
     hereof, a Global Security is exchanged for Certificated Notes, such Notes
     may be exchanged for one another only in accordance with such procedures as
     are substantially consistent with the provisions above (including
     certification requirements intended to ensure that such transfers are to a
     QIB who is also a Qualified Purchaser or are to a non-U.S. Person, or
     otherwise comply with Rule 144A or Regulation S, as the case may be) and as
     may be from time to time adopted by the Issuer, the Co-Issuer and the
     Trustee.

          (f) Transfers of Definitive Class A-1AR Notes. Each Person who becomes
an owner of the Definitive Class A-1AR Notes will be required to make the
representations set forth in Section 2.5(h)(ii) through (xx) and to further
represent and agree as follows:

          (i) the owner is one of the following:

               (1) (A) a Qualified Purchaser, (B) a QIB, (C) is aware that the
          sale of the Definitive Class A-1AR Notes to it is being made in
          reliance on the exemption from registration provided by Rule 144A, (D)
          is acquiring the Definitive Class A-1AR Notes for its own account or
          for one or more accounts, each of which is a QIB who is a Qualified
          Purchaser, and as to each of which the owner exercises sole investment
          discretion, and (E) is acquiring the Definitive Class A-1AR Notes in a
          minimum principal amount of not less than $500,000 for each such
          account; or

               (2) (A) is not a U.S. Person, (B) is aware that the sale of the
          Definitive Class A-1AR Notes to it is being made in reliance on the
          exemption from registration provided by Regulation S and (C)
          understands that the Definitive


                                      -99-

<PAGE>

          Class A-1AR Notes offered in reliance on Regulation S will bear the
          legend set forth in Exhibit A-3;

          and in each case the owner has such knowledge and experience in
          financial and business matters as to be capable of evaluating the
          merits and risks of its investment in the Definitive Class A-1AR Notes
          and the owner and any accounts for which it is acting are each able to
          bear the economic risk of the investment; and

          (ii) before any interest in a Definitive Class A-1AR Note may be
     offered, resold, pledged or otherwise transferred, the transferee and
     transferor shall be required to provide the Trustee, with a written
     certification substantially in the forms of Exhibit K and L hereto as to
     compliance with the transfer restrictions and the owner must inform a
     prospective transferee of the transfer restrictions.

          (g) Removal of Legend. If Notes are issued upon the transfer, exchange
or replacement of Notes bearing the applicable legends set forth in Exhibits
A-1, A-2, A-3, B, C, D, E, F, G and H hereto, and if a request is made to remove
such applicable legend on such Notes, the Notes so issued shall bear such
applicable legend, or such applicable legend shall not be removed, as the case
may be, unless there is delivered to the Issuer and the Co-Issuer such
satisfactory evidence, which may include an Opinion of Counsel of an attorney at
law licensed to practice law in the State of New York (and addressed to the
Issuer and the Trustee), as may be reasonably required by the Issuer and the
Co-Issuer, if applicable, to the effect that neither such applicable legend nor
the restrictions on transfer set forth therein are required to ensure that
transfers thereof comply with the provisions of Rule 144A or Regulation S, as
applicable, the Investment Company Act or ERISA. So long as the Issuer or the
Co-Issuer is relying on an exemption under or promulgated pursuant to the
Investment Company Act, the Issuer or the Co-Issuer shall not remove that
portion of the legend required to maintain an exemption under or promulgated
pursuant to the Investment Company Act. Upon provision of such satisfactory
evidence, as confirmed in writing by the Issuer and the Co-Issuer, if
applicable, to the Trustee, the Trustee, at the direction of the Issuer and the
Co-Issuer, if applicable, shall authenticate and deliver Notes that do not bear
such applicable legend.

          (h) Each beneficial owner of Rule 144A Global Securities shall be
deemed to represent and agree as follows (terms used in this paragraph that are
defined in Rule 144A are used herein as defined therein):

          (i) In the case of a Rule 144A Global Security, the owner is (A) a QIB
     and a Qualified Purchaser, (B) is aware that the sale of the Notes to it
     (other than the initial sale by the Issuer and the Co-Issuer, as
     applicable,) is being made in reliance on the exemption from registration
     provided by Rule 144A, (C) is acquiring the Notes for its own account or
     for one or more accounts, each of which is a QIB and a Qualified Purchaser,
     and as to each of which the owner exercises sole investment discretion, and
     (D) is acquiring the Notes in a principal amount of not less than $100,000,
     for each such account.


                                      -100-

<PAGE>

          (ii) The owner understands that the Notes are being offered only in a
     transaction not involving any public offering in the United States within
     the meaning of the Securities Act, the Notes have not been and shall not be
     registered under the Securities Act, and, if in the future the owner
     decides to offer, resell, pledge or otherwise transfer the Notes, such
     Notes may only be offered, resold, pledged or otherwise transferred only in
     accordance with this Indenture and the applicable legend on such Notes set
     forth in Exhibits A-1, A-2, A-3, B, C, D, E, F, G and H. The owner
     acknowledges that no representation is made by the Issuer, the Co-Issuer or
     the Dealers, as the case may be, as to the availability of any exemption
     under the Securities Act or any state securities laws for resale of the
     Notes.

          (iii) The owner is not purchasing the Notes with a view to the resale,
     distribution or other disposition thereof in violation of the Securities
     Act. The owner understands that an investment in the Notes involves certain
     risks, including the risk of loss of all or a substantial part of its
     investment under certain circumstances. The owner has had access to such
     financial and other information concerning the Issuer, the Co-Issuer and
     the Notes as it deemed necessary or appropriate in order to make an
     informed investment decision with respect to its purchase of the Notes,
     including, without limitation, an opportunity to ask questions of and
     request information from the Collateral Manager, the Initial Purchaser, the
     Issuer and the Co-Issuer and access to such legal and tax representation or
     counsel as the owner deemed necessary or appropriate.

          (iv) In connection with the purchase of the Notes (A) none of the
     Issuer, the Co-Issuer, the Dealers, the Collateral Manager or the Trustee
     is acting as a fiduciary or financial or investment adviser for the owner;
     (B) the owner is not relying (for purposes of making any investment
     decision or otherwise) upon any advice, counsel or representations (whether
     written or oral) of the Issuer, the Co-Issuer, the Dealers, the Collateral
     Manager or the Trustee other than in a current final offering memorandum
     for such Notes and any representations expressly set forth in a written
     agreement with such party; (C) none of the Issuer, the Co-Issuer, the
     Dealers, the Collateral Manager or the Trustee has given to the owner
     (directly or indirectly through any other person) any assurance, guarantee,
     or representation whatsoever as to the expected or projected success,
     profitability, return, performance, result, effect, consequence, or benefit
     (including legal, regulatory, tax, financial, accounting, or otherwise) of
     its purchase; (D) the owner has consulted with its own legal, regulatory,
     tax, business, investment, financial, and accounting advisers to the extent
     it has deemed necessary, and it has made its own investment decisions
     (including decisions regarding the suitability of any transaction pursuant
     to this Indenture) based upon its own judgment and upon any advice from
     such advisers as it has deemed necessary and not upon any view expressed by
     the Issuer, the Co-Issuer, the Dealers, the Collateral Manager or the
     Trustee; and (E) the owner is purchasing the Notes with a full
     understanding of all of the terms, conditions and risks thereof (economic
     and otherwise), and is capable of assuming and willing to assume
     (financially and otherwise) these risks.

          (v) The owner understands that the Notes shall bear the applicable
     legend set forth in Exhibits A-1, A-2, A-3, B, C, D, E, F, G and H. The
     Rule 144A Global Securities may not at any time be held by or on behalf of
     any U.S. Person that is not a


                                      -101-

<PAGE>

     QIB who is a Qualified Purchaser. The owner must inform a prospective
     transferee of the transfer restrictions.

          (vi) The Notes will bear the applicable legend set forth in Exhibits
     A-1, A-2, A-3, B, C, D, E, F, G and H unless the Issuer and the Co-Issuer
     determine otherwise in compliance with applicable law.

          (vii) Unless a prospective Holder of a Note otherwise provides another
     representation acceptable to the Trustee, the Collateral Manager, the
     Issuer and the Co-Issuer, each Holder of a Global Security, by its
     acquisition thereof, shall be deemed to have represented to the Issuer, the
     Co-Issuer, the Collateral Manager and the Trustee that either (A) no part
     of the funds being used to pay the purchase price for such Notes
     constitutes an asset of any "employee benefit plan" (as defined in Section
     3(3) of ERISA) or "plan" (as defined in Section 4975(e)(1) of the Code)
     that is subject to Title I of ERISA or Section 4975 of the Code or any
     other employee benefit plan or plan which is subject to any federal, state
     or local law ("Similar Law") that is substantially similar to Section 406
     of ERISA or Section 4975 of the Code (each a "Benefit Plan", or an entity
     whose underlying assets include plan assets of any such Benefit Plan, or
     (B) if the funds being used to pay the purchase price for such Notes
     include plan assets of any Benefit Plan, its purchase and holding will not
     constitute or result in a non-exempt prohibited transaction under Section
     406 of ERISA or Section 4975 of the Code, or in the case of any Benefit
     Plan subject to Similar Law, do not result in a non-exempt violation of
     Similar Law.

          (viii) The owner shall not, at any time, offer to buy or offer to sell
     the Notes by any form of general solicitation or advertising, including,
     but not limited to, any advertisement, article, notice or other
     communication published in any newspaper, magazine or similar medium or
     broadcast over television or radio or at a seminar or meeting whose
     attendees have been invited by general solicitations or advertising.

          (ix) The owner is not a member of the public in the Cayman Islands,
     within the meaning of Section 194 of the Cayman Islands Companies Law (2004
     Revision).

          (x) The owner understands that the Issuer, the Co-Issuer, the Trustee
     or the Paying Agent shall require certification acceptable to it (A) as a
     condition to the payment of principal of and interest on (and commitment
     fees in respect of) any Notes without, or at a reduced rate of, U.S.
     withholding or backup withholding tax, and (B) to enable the Issuer, the
     Co-Issuer, the Trustee and the Paying Agent to determine their duties and
     liabilities with respect to any taxes or other charges that they may be
     required to pay, deduct or withhold from payments in respect of such Notes
     or the Holder of such Notes under any present or future law or regulation
     of the Cayman Islands or the United States or any present or future law or
     regulation of any political subdivision thereof or taxing authority therein
     or to comply with any reporting or other requirements under any such law or
     regulation. Such certification may include U.S. federal income tax forms
     (such as IRS Form W-8BEN (Certification of Foreign Status of Beneficial
     Owner), IRS Form W-8IMY (Certification of Foreign Intermediary Status), IRS
     Form W-9 (Request for Taxpayer Identification Number and Certification), or
     IRS Form W-8ECI (Certification

     of Foreign Person's Claim for Exemption from Withholding on Income
     Effectively Connected with Conduct of a U.S. Trade or Business) or any
     successors to such IRS forms). In addition, the Issuer, the Co-Issuer, the
     Trustee or the Paying Agent may require certification acceptable to it to
     enable the Issuer to qualify for a reduced rate of withholding in any
     jurisdiction from or through which the Issuer receives payments on its
     assets. Each owner agrees to provide any certification requested pursuant
     to this paragraph and to update or replace such form or certification in
     accordance with its terms or its subsequent amendments.

          (xi) The owner hereby acknowledges that it is its intent and that it
     understands it is the intent of the Issuer that, for purposes of U.S.
     federal, state and local income and franchise tax and any other income
     taxes, for so long as a direct or indirect wholly-owned subsidiary of the
     Arbor Parent owns 100% of the Preferred Shares and the ordinary shares of
     the Issuer, the Issuer will be treated as a Qualified REIT Subsidiary and
     the Notes will be treated as indebtedness solely of the Arbor Parent, and
     (B) the Preferred Shares will be treated as equity; the owner agrees to
     such treatment and agrees to take no action inconsistent with such
     treatment.

          (xii) The owner, if not a "United States person" (as defined in
     Section 7701(a)(30) of the Code), either: (A) is not a bank (within the
     meaning of Section 881(c)(3)(A) of the Code) (and see (C) below); (B) is a
     bank that has provided an IRS Form W-8ECI representing that all payments
     received or to be received by it from the Issuer are effectively connected
     with the conduct of a trade or business in the United States; or (C) is a
     bank and is, or is not a bank (within the meaning of Section 881(c)(3)(A)
     of the Code) but with respect to commitment fees is, eligible for benefits
     under an income tax treaty with the United States that eliminates U.S.
     federal income taxation of U.S. source interest and commitment fees not
     attributable to a permanent establishment in the United States and the
     Issuer is treated as a fiscally transparent entity (as defined in Treasury
     Regulations section 1.894-1(d)(3)(iii)) under the laws of owner's
     jurisdiction with respect to payments made on the Collateral Debt
     Securities held by the Issuer.

          (xiii) The owner understands that the Notes have not been approved or
     disapproved by the SEC or any other governmental authority or agency or any
     jurisdiction and that neither the SEC nor any other governmental authority
     or agency has passed upon the accuracy of the final offering memorandum
     relating to the Notes. The owner further understands that any
     representation to the contrary is a criminal offense.

          (xiv) The owner will, prior to any sale, pledge or other transfer by
     such owner of any Note (or interest therein), obtain from the prospective
     transferee, and deliver to the Trustee, a duly executed transferee
     certificate addressed to each of the Trustee, the Issuer, the Co-Issuer and
     the Collateral Manager in the form of the relevant exhibit attached hereto,
     and such other certificates and other information as the Issuer, the
     Co-Issuer, the Collateral Manager or the Trustee may reasonably require to
     confirm that the proposed transfer complies with the transfer restrictions
     contained herein.


                                      -103-

<PAGE>

          (xv) The owner agrees that no Note may be purchased, sold, pledged or
     otherwise transferred in an amount less than the minimum denomination set
     forth in this Indenture. In addition, the owner understands that the Notes
     will be transferable only upon registration of the transferee in the Note
     Register of the Issuer following delivery to the Note Registrar of a duly
     executed transfer certificate (and with respect to the Class A-1AR Notes,
     the Definitive Class A-1AR Notes to be transferred), and any other
     certificates and other information required by this Indenture.

          (xvi) The owner is aware and agrees that no Note (or beneficial
     interest therein) may be offered or sold, pledged or otherwise transferred
     (i) to a transferee taking delivery of such Note represented by a Rule 144A
     Global Security except (A) to a transferee that the owner reasonably
     believes is a QIB, purchasing for its account, to which notice is given
     that the resale, pledge or other transfer is being made in reliance on the
     exemption from the registration requirements of the Securities Act provided
     by Rule 144A or another Person the sale to which is exempt under the
     Securities Act, (B) to a transferee that is a Qualified Purchaser, and (C)
     if such transfer is made in accordance with any applicable securities laws
     of any state of the United States and any other relevant jurisdiction, (ii)
     to a transferee taking delivery of such Note represented by a Regulation S
     Global Security except (A) to a transferee that is acquiring such interest
     in an offshore transaction in accordance with Rule 904 of Regulation S, (B)
     to a transferee that is not a U.S. resident (within the meaning of the
     Investment Company Act) unless such transferee is a Qualified Purchaser,
     (C) such transfer is made in compliance with the other requirements set
     forth in this Indenture and (D) if such transfer is made in accordance with
     any applicable securities laws of any state of the United States and any
     other jurisdiction or (iii) if such transfer would have the effect of
     requiring the Issuer or the Collateral to register as an "investment
     company" under the Investment Company Act.

          (xvii) The owner understands that there is no market for the Notes and
     that no assurances can be given as to the liquidity of any trading market
     for the Notes and that it is unlikely that a trading market for the Notes
     will develop. The owner further understands that, although the Dealers may
     from time to time make a market in the Notes, the Dealers are not under any
     obligation to do so and, following the commencement of any market-making,
     may discontinue the same at any time. Accordingly, the owner must be
     prepared to hold the Notes until the Stated Maturity.

          (xviii) The owner agrees that (i) any sale, pledge or other transfer
     of a Note (or any beneficial interest therein) made in violation of the
     transfer restrictions contained in this Indenture, or made based upon any
     false or inaccurate representation made by the owner or a transferee to the
     Issuer, the Trustee or the Note Registrar, will be void and of no force or
     effect and (ii) none of the Issuer, the Trustee and the Note Registrar has
     any obligation to recognize any sale, pledge or other transfer of a Note
     (or any beneficial interest therein) made in violation of any such transfer
     restriction or made based upon any such false or inaccurate representation.

          (xix) The owner approves and consents to any direct trades between the
     Issuer and the Collateral Manager and/or its affiliates that is permitted
     under the terms of this Indenture and the Collateral Management Agreement.


                                      -104-

          (xx) The owner acknowledges that the Issuer, the Co-Issuer, the
     Trustee, the Note Registrar, the Collateral Manager, the Dealers and others
     will rely upon the truth and accuracy of the foregoing acknowledgments,
     representations and agreements and agrees that, if any of the
     acknowledgments, representations or warranties made or deemed to have been
     made by it in connection with its purchase of the Notes are no longer
     accurate, the owner will promptly notify the Issuer, the Co-Issuer, the
     Trustee, Note Registrar, the Collateral Manager and the Dealers.

          (i) Each beneficial owner of Regulation S Global Securities shall be
deemed to have made the representations set forth in clauses (ii) through (iv)
and (vi) through (xx) of Section 2.5(h) and shall be deemed to have further
represented and agreed as follows:

          The owner is aware that the sale of such Notes to it is being made in
reliance on the exemption from registration provided by Regulation S and
understands that the Notes offered in reliance on Regulation S will bear the
appropriate legend set forth in Exhibits A-1, A-2, B, C, D, E, F, G and H
hereto, and be represented by one or more Regulation S Global Securities. The
Notes so represented may not at any time be held by or on behalf of U.S.
Persons. Each of the owner and the related Holder is not, and shall not be, a
U.S. Person. Before any interest in a Regulation S Global Security may be
offered, resold, pledged or otherwise transferred to a person who takes delivery
in the form of a Rule 144A Global Security, the transferee shall be required to
provide the Trustee with a written certification substantially in the form of
Exhibits K and L (as applicable) hereto as to compliance with the transfer
restrictions. The owner must inform a prospective transferee of the transfer
restrictions.

          (j) Any purported transfer of a Note not in accordance with this
Section 2.5 shall be null and void and shall not be given effect for any purpose
hereunder.

          (k) Notwithstanding anything contained in this Indenture to the
contrary, neither the Trustee nor the Notes Registrar (nor any other Transfer
Agent) shall be responsible or liable for compliance with applicable federal or
state securities laws (including, without limitation, the Securities Act or Rule
144A or Regulation S promulgated thereunder), the Investment Company Act, ERISA
or the Code (or any applicable regulations thereunder); provided, however, that
if a specified transfer certificate or Opinion of Counsel is required by the
express terms of this Section 2.5 to be delivered to the Trustee or Notes
Registrar prior to registration of transfer of a Note, the Trustee and/or Notes
Registrar, as applicable, is required to request, as a condition for registering
the transfer of the Note, such certificate or Opinion of Counsel and to examine
the same to determine whether it conforms on its face to the requirements hereof
(and the Trustee or Notes Registrar, as the case may be, shall promptly notify
the party delivering the same if it determines that such certificate or Opinion
of Counsel does not so conform).

          (l) If the Trustee determines or is notified by the Issuer, the
Co-Issuer or the Collateral Manager that (i) a transfer or attempted or
purported transfer of any interest in any Note was consummated in compliance
with the provisions of this Section 2.5 on the basis of a materially incorrect
certification from the transferee or purported transferee, (ii) a transferee
failed to deliver to the Trustee any certification required to be delivered
hereunder or (iii) the holder of any interest in a Note is in breach of any
representation or agreement set forth in any


                                     -105-

<PAGE>

certification or any deemed representation or agreement of such holder, the
Trustee shall not register such attempted or purported transfer and if a
transfer has been registered, such transfer shall be absolutely null and void ab
initio and shall vest no rights in the purported transferee (such purported
transferee, a "Disqualified Transferee") and the last preceding holder of such
interest in such Note that was not a Disqualified Transferee shall be restored
to all rights as a Holder thereof retroactively to the date of transfer of such
Note by such Holder.

          In addition, the Trustee may require that the interest in the Note
referred to in (i), (ii) or (iii) in the preceding paragraph be transferred to
any person designated by the Issuer or the Collateral Manager at a price
determined by the Issuer or the Collateral Manager, as applicable, based upon
its estimation of the prevailing price of such interest and each Holder, by
acceptance of an interest in a Note, authorizes the Trustee to take such action.
In any case, the Trustee shall not be held responsible for any losses that may
be incurred as a result of any required transfer under this Section 2.5(l).

          (m) Each Holder of Notes approves and consents to (i) the initial
purchase of the Collateral Debt Securities by the Issuer from Affiliates of the
Collateral Manager on or prior to the Closing Date and (ii) any other
transaction between the Issuer and the Collateral Manager or its Affiliates that
are permitted under the terms of this Indenture or the Collateral Management
Agreement.

          Section 2.6 Mutilated, Defaced, Destroyed, Lost or Stolen Note.

          If (a) any mutilated or defaced Note is surrendered to a Transfer
Agent, or if there shall be delivered to the Issuer, the Co-Issuer, the Trustee
and the relevant Transfer Agent (each a "Specified Person") evidence to their
reasonable satisfaction of the destruction, loss or theft of any Note, and (b)
there is delivered to the Specified Person such security or indemnity as may be
required by each Specified Person to save each of them and any agent of any of
them harmless (an unsecured indemnity agreement delivered to the Trustee by an
institutional investor with a net worth of at least $200,000,000 being deemed
sufficient to satisfy such security or indemnity requirement), then, in the
absence of notice to the Specified Persons that such Note has been acquired by a
bona fide purchaser, the Issuer and the Co-Issuer shall execute and, upon Issuer
Request, the Trustee shall authenticate and deliver, in lieu of any such
mutilated, defaced, destroyed, lost or stolen Note, a new Note, of like tenor
(including the same date of issuance) and equal principal amount, registered in
the same manner, dated the date of its authentication, bearing interest from the
date to which interest has been paid on the mutilated, defaced, destroyed, lost
or stolen Note and bearing a number not contemporaneously outstanding.

          If, after delivery of such new Note, a bona fide purchaser of the
predecessor Note presents for payment, transfer or exchange such predecessor
Note, any Specified Person shall be entitled to recover such new Note from the
Person to whom it was delivered or any Person taking therefrom, and each
Specified Person shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
such Specified Person in connection therewith.

          In case any such mutilated, defaced, destroyed, lost or stolen Note
has become due and payable, the Issuer and the Co-Issuer, if applicable, in
their discretion may, instead of


                                     -106-

<PAGE>

issuing a new Note, pay such Note without requiring surrender thereof except
that any mutilated or defaced Note shall be surrendered.

          Upon the issuance of any new Note under this Section 2.6, the Issuer
and the Co-Issuer, if applicable, may require the payment by the registered
Holder thereof of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses (including the
fees and expenses of the Trustee) connected therewith.

          Every new Note issued pursuant to this Section 2.6 in lieu of any
mutilated, defaced, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Issuer and the Co-Issuer, if
applicable, and such new Note shall be entitled, subject to the second paragraph
of this Section 2.6, to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

          The provisions of this Section 2.6 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, defaced, destroyed, lost or stolen Notes.

          Section 2.7 Payment of Principal and Interest and Class A-1AR
Commitment Fee and Other Amounts; Principal and Interest Rights Preserved.

          (a) The Class A-1A Notes shall accrue interest during each Interest
Accrual Period at the Class A-1A Rate. Interest on each Class A-1A Note shall be
due and payable on each Payment Date immediately following the related Interest
Accrual Period in the proportion that the outstanding principal amount of such
Class A-1A Note bears to the Aggregate Outstanding Amount of all Class A-1A
Notes; provided, however, that the payment of interest on the Class A-1A Notes
is subordinated to the payment on each Payment Date of certain amounts in
accordance with the Priority of Payments.

          (b) The Class A-1AR Notes shall accrue interest during each Interest
Accrual Period at the Class A-1AR Rate. In addition, the Class A-1AR Notes shall
accrue the Class A-1AR Commitment Fee in accordance with the definition of such
term. Except as described in Section 18.2 of this Indenture, interest on each
Class A-1AR Note shall be due and payable on each Payment Date immediately
following the related Interest Accrual Period in the proportion determined in
accordance with the Class A-1AR Interest Allocation Percentage; provided that
accrued interest in respect of amounts borrowed under the Class A-1AR Notes
during the period following the Determination Date through the related Payment
Date will be payable without additional interest thereon on the next succeeding
Payment Date; and provided, further, however, that the payment of interest on
the Class A-1AR Notes is subordinated to the payment on each Payment Date of
certain amounts in accordance with the Priority of Payments.

          (c) The Class A-2 Notes shall accrue interest during each Interest
Accrual Period at the Class A-2 Rate. Interest on each Class A-2 Note shall be
due and payable on each Payment Date immediately following the related Interest
Accrual Period in the proportion that the outstanding principal amount of such
Class A-2 Note bears to the Aggregate Outstanding Amount of all Class A-2 Notes;
provided, however, that the payment of interest on the Class A-2 Notes is
subordinated to the payment on each Payment Date of the interest due and payable
on


                                     -107-

<PAGE>

the Class A-1 Notes (including any Class A-1 Defaulted Interest Amount) and the
Class A-1AR Commitment Fee and certain other amounts in accordance with the
Priority of Payments.

          (d) The Class B Notes shall accrue interest during each Interest
Accrual Period at the Class B Rate. Interest on each Class B Note shall be due
and payable on each Payment Date immediately following the related Interest
Accrual Period in the proportion that the outstanding principal amount of such
Class B Note bears to the Aggregate Outstanding Amount of all Class B Notes;
provided, however, that the payment of interest on the Class B Notes is
subordinated to the payment on each Payment Date of the interest due and payable
on the Class A Notes (including any Class A Defaulted Interest Amount) and the
Class A-1AR Commitment Fee and certain other amounts in accordance with the
Priority of Payments.

          (e) The Class C Notes shall accrue interest during each Interest
Accrual Period at the Class C Rate. Interest on each Class C Note shall be due
and payable on each Payment Date immediately following the related Interest
Accrual Period in the proportion that the outstanding principal amount of such
Class C Note bears to the Aggregate Outstanding Amount of all Class C Notes;
provided, however, that the payment of interest on the Class C Notes is
subordinated to the payment on each Payment Date of the interest due and payable
on the Class A Notes and the Class B Notes (including any Class A Defaulted
Interest Amount and Class B Defaulted Interest Amount) and the Class A-1AR
Commitment Fee and certain other amounts in accordance with the Priority of
Payments.

          For so long as any Class B Notes are Outstanding, any payment of
interest due on the Class C Notes which is not available to be paid (the "Class
C Capitalized Interest") in accordance with the Priority of Payments on any
Payment Date shall not be considered "due and payable" for the purpose of
Section 5.1(a) hereof (and the failure to pay such Class C Capitalized Interest
shall not be an Event of Default) until the Payment Date on which funds are
available to pay all or any portion of such Class C Capitalized Interest in
accordance with the Priority of Payments. On or after such Payment Date, only
such portion of any payment of Class C Capitalized Interest for which funds are
available in accordance with the Priority of Payments shall be considered "due
and payable" and the failure to pay such portion of Class C Capitalized Interest
shall be an Event of Default. Class C Capitalized Interest shall be added to the
principal amount of the Class C Notes, shall bear interest thereafter at the
Class C Rate (to the extent lawful) and shall be payable on the first Payment
Date on which funds are permitted to be used for such purpose in accordance with
the Priority of Payments. On or after the Payment Date on which the Class B
Notes are no longer Outstanding, to the extent interest is due (excluding any
previously deferred Class C Capitalized Interest) but not paid on the Class C
Notes, the failure to pay such interest shall constitute an Event of Default
hereunder.

          (f) The Class D Notes shall accrue interest during each Interest
Accrual Period at the Class D Rate. Interest on each Class D Note shall be due
and payable on each Payment Date immediately following the related Interest
Accrual Period in the proportion that the outstanding principal amount of such
Class D Note bears to the Aggregate Outstanding Amount of all Class D Notes;
provided, however, that, except to the extent set forth in the Priority of
Payments, the payment of interest on the Class D Notes is subordinated to the
payment on each Payment Date of the interest due and payable on the Class A
Notes, the Class B Notes and the Class C Notes (including any Class A Defaulted
Interest Amount, Class B

Defaulted Interest Amount, Class C Defaulted Interest Amount and Class C
Capitalized Interest) and the Class A-1AR Commitment Fee and certain other
amounts in accordance with the Priority of Payments.

          For so long as any Class C Notes are Outstanding, any payment of
interest due on the Class D Notes which is not available to be paid ("Class D
Capitalized Interest") in accordance with the Priority of Payments on any
Payment Date shall not be considered "due and payable" for the purpose of
Section 5.1(a) hereof (and the failure to pay such Class D Capitalized Interest
shall not be an Event of Default) until the Payment Date on which funds are
available to pay all or any portion of such Class D Capitalized Interest in
accordance with the Priority of Payments. On or after such Payment Date, only
such portion of any payment of Class D Capitalized Interest for which funds are
available in accordance with the Priority of Payments shall be considered "due
and payable" and the failure to pay such portion of Class D Capitalized Interest
shall be an Event of Default. Class D Capitalized Interest shall be added to the
principal amount of the Class D Notes, shall bear interest thereafter at the
Class D Rate (to the extent lawful) and shall be payable on the first Payment
Date on which funds are permitted to be used for such purpose in accordance with
the Priority of Payments. On or after the Payment Date on which the Class C
Notes are no longer Outstanding, to the extent interest is due (excluding any
previously deferred Class D Capitalized Interest) but not paid on the Class D
Notes, the failure to pay such interest shall constitute an Event of Default
hereunder.

          (g) The Class E Notes shall accrue interest during each Interest
Accrual Period at the Class E Rate. Interest on each Class E Note shall be due
and payable on each Payment Date immediately following the related Interest
Accrual Period in the proportion that the outstanding principal amount of such
Class E Note bears to the Aggregate Outstanding Amount of all Class E Notes;
provided, however, that, except to the extent set forth in the Priority of
Payments, the payment of interest on the Class E Notes is subordinated to the
payment on each Payment Date of the interest due and payable on the Class A
Notes, the Class B Notes, the Class C Notes and the Class D Notes (including any
Class A Defaulted Interest Amount, Class B Defaulted Interest Amount, Class C
Defaulted Interest Amount, Class C Capitalized Interest, Class D Defaulted
Interest Amount and Class D Capitalized Interest) and the Class A-1AR Commitment
Fee and certain other amounts in accordance with the Priority of Payments.

          For so long as any Class D Notes are Outstanding, any payment of
interest due on the Class E Notes which is not available to be paid (the "Class
E Capitalized Interest") in accordance with the Priority of Payments on any
Payment Date shall not be considered "due and payable" for the purpose of
Section 5.1(a) hereof (and the failure to pay such Class E Capitalized Interest
shall not be an Event of Default) until the Payment Date on which funds are
available to pay all or any portion of such Class E Capitalized Interest in
accordance with the Priority of Payments. On or after such Payment Date, only
such portion of any payment of Class E Capitalized Interest for which funds are
available in accordance with the Priority of Payments shall be considered "due
and payable" and the failure to pay such portion of Class E Capitalized Interest
shall be an Event of Default. Class E Capitalized Interest shall be added to the
principal amount of the Class E Notes, shall bear interest thereafter at the
Class E Rate (to the extent lawful) and shall be payable on the first Payment

          (n) As a condition to the payment of principal of and interest on any
Note without the imposition of U.S. withholding tax, the Issuer shall require
certification acceptable to it to enable the Issuer, the Co-Issuer, the Trustee,
the Preferred Shares Paying Agent and the Paying Agent to determine their duties
and liabilities with respect to any taxes or other charges that they may be
required to deduct or withhold from payments in respect of such Security under


                                     -114-

<PAGE>

any present or future law or regulation of the United States or any present or
future law or regulation of any political subdivision thereof or taxing
authority therein or to comply with any reporting or other requirements under
any such law or regulation. Such certification may include U.S. federal income
tax forms (such as IRS Form W-8BEN (Certification of Foreign Status of
Beneficial Owner), Form W-8IMY (Certification of Foreign Intermediary Status),
IRS Form W-9 (Request for Taxpayer Identification Number and Certification), or
IRS Form W-8ECI (Certification of Foreign Person's Claim for Exemption from
Withholding on Income Effectively Connected with Conduct of a U.S. Trade or
Business) or any successors to such IRS forms). In addition, each of the Issuer,
Co-Issuer, the Trustee, Preferred Shares Paying Agent or any Paying Agent may
require certification acceptable to it to enable the Issuer to qualify for a
reduced rate of withholding in any jurisdiction from or through which the Issuer
receives payments on its assets. Each Holder and each beneficial owner of Notes
agree to provide any certification requested pursuant to Section 2.7(n) and to
update or replace such form or certification in accordance with its terms or its
subsequent amendments.

          (o) Payments in respect of interest on and principal of the Notes
shall be payable by wire transfer in immediately available funds to a Dollar
account maintained by the Holder or its nominee; provided that the Holder has
provided wiring instructions to the Trustee on or before the related Record Date
or, if wire transfer cannot be effected, by a Dollar check drawn on a bank in
the United States, or by a Dollar check mailed to the Holder at its address in
the Notes Register. The Issuer expects that the Depository or its nominee, upon
receipt of any payment of principal or interest in respect of a Global Security
held by the Depository or its nominee, shall immediately credit the applicable
Agent Members' accounts with payments in amounts proportionate to the respective
beneficial interests in such Global Security as shown on the records of the
Depository or its nominee. The Issuer also expects that payments by Agent
Members to owners of beneficial interests in such Global Security held through
Agent Members will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the names of nominees for such customers. Such payments will be the
responsibility of the Agent Members. Upon final payment due on the Maturity of a
Note, the Holder thereof shall present and surrender such Note at the Corporate
Trust Office of the Trustee or at the office of the Paying Agent (outside of the
United States if then required by applicable law in the case of a Certificated
Note issued in exchange for a beneficial interest in the Regulation S Global
Security) on or prior to such Maturity. None of the Issuer, the Co-Issuer, the
Trustee or the Paying Agent will have any responsibility or liability with
respect to any records maintained by the Holder of any Note with respect to the
beneficial holders thereof or payments made thereby on account of beneficial
interests held therein. In the case where any final payment of principal and
interest is to be made on any Note (other than on the Stated Maturity thereof)
the Issuer or, upon Issuer Request, the Trustee, in the name and at the expense
of the Issuer, shall not more than 30 nor fewer than five Business Days prior to
the date on which such payment is to be made, mail to the Persons entitled
thereto at their addresses appearing on the Notes Register, a notice which shall
state the date on which such payment will be made and the amount of such payment
per $500,000 initial principal amount of Notes and shall specify the place where
such Notes may be presented and surrendered for such payment.

          (p) Subject to the provisions of Sections 2.7(a) through (m) and
Section 2.7(u) hereof, Holders of Notes as of the Record Date in respect of a
Payment Date shall be entitled to


                                     -115-

<PAGE>

the interest accrued and payable in accordance with the Priority of Payments and
principal payable in accordance with the Priority of Payments on such Payment
Date. All such payments that are mailed or wired and returned to the Paying
Agent shall be held for payment as herein provided at the office or agency of
the Issuer and the Co-Issuer to be maintained as provided in Section 7.2 (or
returned to the Trustee).

          (q) Interest on any Note which is payable, and is punctually paid or
duly provided for, on any Payment Date shall be paid to the Person in whose name
that Note (or one or more predecessor Notes) is registered at the close of
business on the Record Date for such interest.

          (r) Payments of principal to Holders of the Notes of each Class shall
be made in the proportion that the Aggregate Outstanding Amount of the Notes of
such Class registered in the name of each such Holder on such Record Date bears
to the Aggregate Outstanding Amount of all Notes of such Class on such Record
Date.

          (s) Interest accrued with respect to the Notes shall be calculated as
described in the applicable form of Note attached hereto.

          (t) All reductions in the principal amount of a Note (or one or more
predecessor Notes) effected by payments of installments of principal made on any
Payment Date, Redemption Date or upon Maturity shall be binding upon all future
Holders of such Note and of any Note issued upon the registration of transfer
thereof or in exchange therefor or in lieu thereof, whether or not such payment
is noted on such Note.

          (u) Notwithstanding anything contained in this Indenture to the
contrary, the obligations of the Issuer and the Co-Issuer under the Notes, this
Indenture and the other Transaction Documents are non-recourse obligations of
the Issuer and the Co-Issuer payable solely from the Assets and following
realization of the Assets, all obligations of the Co-Issuers and any claims of
the Noteholders, the Trustee or any other parties to any Transaction Documents
shall be extinguished and shall not thereafter revive. No recourse shall be had
for the payment of any amount owing in respect of the Notes against any Officer,
director, employee, shareholder, limited partner or incorporator of the Issuer,
the Co-Issuer or any of their respective successors or assigns for any amounts
payable under the Notes or this Indenture. It is understood that the foregoing
provisions of this paragraph shall not (i) prevent recourse to the Assets for
the sums due or to become due under any security, instrument or agreement which
is part of the Assets or (ii) constitute a waiver, release or discharge of any
indebtedness or obligation evidenced by the Notes or secured by this Indenture
(to the extent it relates to the obligation to make payments on the Notes) until
such Assets have been realized, whereupon any outstanding indebtedness or
obligation in respect of the Notes, this Indenture and the other Transaction
Documents shall be extinguished and shall not thereafter revive. It is further
understood that the foregoing provisions of this paragraph shall not limit the
right of any Person to name the Issuer or the Co-Issuer as a party defendant in
any Proceeding or in the exercise of any other remedy under the Notes or this
Indenture, so long as no judgment in the nature of a deficiency judgment or
seeking personal liability shall be asked for or (if obtained) enforced against
any such Person or entity.


                                     -116-

          (v) Subject to the foregoing provisions of this Section 2.7, each Note
delivered under this Indenture and upon registration of transfer of or in
exchange for or in lieu of any other Note shall carry the rights of unpaid
interest and principal that were carried by such other Note.

          (w) Notwithstanding any of the foregoing provisions with respect to
payments of principal of and interest on the Notes (but subject to Sections
2.7(m) and (u)), if the Notes have become or been declared due and payable
following an Event of Default and such acceleration of Maturity and its
consequences have not been rescinded and annulled and the provisions of Section
5.5 are not applicable, then payments of principal of and interest on such Notes
shall be made in accordance with Section 5.7 hereof.

          (x) Payments in respect of the Preferred Shares as contemplated by
Sections 11.1(a)(i)(29) and 11.1(a)(ii)(15) shall be made by the Trustee to the
Preferred Shares Paying Agent.

          Section 2.8 Persons Deemed Owners.

          The Issuer, the Co-Issuer, the Trustee, and any agent of the Issuer,
the Co-Issuer or the Trustee may treat as the owner of a Note the Person in
whose name such Note is registered on the Notes Register on the applicable
Record Date for the purpose of receiving payments of principal of and interest
and other amounts on such Note and on any other date for all other purposes
whatsoever (whether or not such Note is overdue), and none of the Issuer, the
Co-Issuer or the Trustee nor any agent of the Issuer, the Co-Issuer or the
Trustee shall be affected by notice to the contrary; provided, however, that the
Depository, or its nominee, shall be deemed the owner of the Global Securities,
and owners of beneficial interests in Global Securities will not be considered
the owners of any Notes for the purpose of receiving notices. With respect to
the Preferred Shares, on any Payment Date, the Trustee shall deliver to the
Preferred Shares Paying Agent the distributions thereon for distribution to the
Preferred Shareholders.

          Section 2.9 Cancellation.

          All Notes surrendered for payment, registration of transfer, exchange
or redemption, or deemed lost or stolen, shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee, and shall be promptly
canceled by the Trustee and may not be reissued or resold. No Notes shall be
authenticated in lieu of or in exchange for any Notes canceled as provided in
this Section 2.9, except as expressly permitted by this Indenture. All canceled
Notes held by the Trustee shall be destroyed or held by the Trustee in
accordance with its standard retention policy unless the Issuer and the
Co-Issuer shall direct by an Issuer Order that they be returned to them.

          Section 2.10 Global Securities; Temporary Notes.

          (a) In the event that the Depository notifies the Issuer and the
Co-Issuer that it is unwilling or unable to continue as Depository for a Global
Security or if at any time such Depository ceases to be a "Clearing Agency"
registered under the Exchange Act and a successor depository is not appointed by
the Issuer within 90 days of such notice, the Global Securities


                                     -117-

Notes, Class C Notes, Class D Notes, Class E Notes, Class F Notes, Class G Notes
and Class H Notes in definitive registered form without interest coupons (each,
a "Certificated Note") to the beneficial owners (or such owner's nominee)
holding the ownership interests in such Global Security. Any such transfer shall
be made, without charge, and the Trustee shall authenticate and deliver, upon
such transfer of each portion of such Global Security, an equal aggregate
principal amount of Certificated Notes of the same Class and authorized

Global Security shall, except as otherwise provided by Section 2.5(g), bear the
applicable legend set forth in Exhibits A-1, A-2, B, C, D, E, F, G and H, and
shall be subject to the transfer restrictions referred to in such applicable
legend. The Holder of each such registered individual Global Security may
transfer such Global Security by surrendering it at the Corporate Trust Office
of the Trustee, or at the office of the Paying Agent or Irish Paying Agent.

          (c) Subject to the provisions of Section 2.10(b) above, the registered
Holder of a Global Security may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Notes.

          (d) In the event of the occurrence of either of the events specified
in Section 2.10(a) above, the Issuer and the Co-Issuer shall promptly make
available to the Trustee a reasonable supply of Certificated Notes.

          Pending the preparation of Certificated Notes pursuant to this Section
2.10, the Issuer and the Co-Issuer may execute and, upon Issuer Order, the
Trustee shall authenticate and deliver, temporary Class A-1A Notes, Class A-2
Notes, Class B Notes, Class C Notes, Class D Notes, Class E Notes, Class F
Notes, Class G Notes or Class H Notes that are printed, lithographed,
typewritten, mimeographed or otherwise reproduced, in any authorized
denomination, substantially of the tenor of the Certificated Notes in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the Officers executing such Certificated
Notes may determine, as conclusively evidenced by their execution of such
Certificated Notes.

          If temporary Certificated Notes are issued, the Issuer and the
Co-Issuer shall cause permanent Certificated Notes to be prepared without
unreasonable delay. The Certificated Notes shall be printed, lithographed,
typewritten or otherwise reproduced, or provided by any combination thereof, or
in any other manner permitted by the rules and regulations of any applicable
notes exchange, all as determined by the Officers executing such Certificated
Notes. After the preparation of Certificated Notes, the temporary Notes shall be
exchangeable for Certificated Notes upon surrender of the applicable temporary
Class A-1 Notes, Class A-2 Notes, Class B Notes, Class C Notes, Class D Notes,
Class E Notes, Class F Notes, Class G Notes or Class H Notes at the office or
agency maintained by the Issuer and the Co-Issuer for such

purpose, without charge to the Holder. Upon surrender for cancellation of any
one or more temporary Class A-1A Notes, Class A-2 Notes, Class B Notes, Class C
Notes, Class D Notes, Class E Notes, Class F Notes, Class G Notes or Class H
Notes, the Issuer and the Co-Issuer shall execute, and the Trustee shall
authenticate and deliver, in exchange therefor the same aggregate principal
amount of Certificated Notes of authorized denominations. Until so exchanged,
the temporary Class A-1A Notes, Class A-2 Notes, Class B Notes, Class C Notes,
Class D Notes, Class E Notes, Class F Notes, Class G Notes or Class H Notes
shall in all respects be entitled to the same benefits under this Indenture as
Certificated Notes.

          Section 2.11 U.S. Tax Treatment of Notes and the Issuer.

          (a) Each of the Issuer and the Co-Issuer intends that, for U.S.
federal income tax purposes, the Notes be treated as debt and that the Issuer be
treated as a Qualified REIT Subsidiary. Each prospective purchaser and any
subsequent transferee of a Note or any interest therein shall, by virtue of its
purchase or other acquisition of such Note or interest therein, be deemed to
have agreed to treat such Note in a manner consistent with the preceding
sentence for U.S. federal income tax purposes.

          (b) The Issuer and the Co-Issuer shall account for the Notes and
prepare any reports to Noteholders and tax authorities consistent with the
intentions expressed in Section 2.11(a) above.

          (c) Each Holder of Notes shall timely furnish to the Issuer, the
Co-Issuer or its agents any U.S. federal income tax form or certification (such
as IRS Form W-8BEN (Certification of Foreign Status of Beneficial Owner) (with
Part III marked), IRS Form W-8IMY (Certification of Foreign Intermediary
Status), IRS Form W-9 (Request for Taxpayer Identification Number and
Certification), or IRS Form W-8ECI (Certification of Foreign Person's Claim for
Exemption from Withholding on Income Effectively Connected with Conduct of a
U.S. Trade or Business) or any successors to such IRS forms that the Issuer, the
Co-Issuer or its agents may reasonably request and shall update or replace such
forms or certification in accordance with its terms or its subsequent
amendments.

          Section 2.12 Authenticating Agents.

          Upon the request of the Issuer and the Co-Issuer, the Trustee shall,
and if the Trustee so chooses the Trustee may, pursuant to this Indenture,
appoint one or more Authenticating Agents with power to act on its behalf and
subject to its direction in the authentication of Notes in connection with
issuance, transfers and exchanges under Sections 2.4, 2.5, 2.6 and 8.5 hereof,
as fully to all intents and purposes as though each such Authenticating Agent
had been expressly authorized by such Sections to authenticate such Notes. For
all purposes of this Indenture, the authentication of Notes by an Authenticating
Agent pursuant to this Section 2.12 shall be deemed to be the authentication of
Notes by the Trustee.

          Any corporation or banking association into which any Authenticating
Agent may be merged or converted or with which it may be consolidated, or any
corporation or banking association resulting from any merger, consolidation or
conversion to which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate trust business of any


                                     -119-

<PAGE>

Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, without the execution or filing of any further act on the part of the
parties hereto or such Authenticating Agent or such successor corporation. Any
Authenticating Agent may at any time resign by giving written notice of
resignation to the Trustee, the Issuer and the Co-Issuer. The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent, the Issuer and the Co-Issuer. Upon
receiving such notice of resignation or upon such a termination, the Trustee
shall promptly appoint a successor Authenticating Agent and shall give written
notice of such appointment to the Issuer.

          The Trustee agrees to pay to each Authenticating Agent appointed by it
from time to time reasonable compensation for its services, and reimbursement
for its reasonable expenses relating thereto and the Trustee shall be entitled
to be reimbursed for such payments, subject to Section 6.7 hereof. The
provisions of Sections 2.9, 6.4 and 6.5 hereof shall be applicable to any
Authenticating Agent.

          Section 2.13 Forced Sale on Failure to Comply with Restrictions.

          (a) Notwithstanding anything to the contrary elsewhere in this
Indenture, any transfer of a Note or interest therein to a U.S. Person who is
determined not to have been both a QIB and a Qualified Purchaser at the time of
acquisition of the Note or interest therein shall be null and void and any such
proposed transfer of which the Issuer, the Co-Issuer or the Trustee shall have
notice may be disregarded by the Issuer, the Co-Issuer and the Trustee for all
purposes.

          (b) If the Issuer determines that any Holder of a Note has not
satisfied the applicable requirement described in Section 2.13(a) above (any
such person a "Non-Permitted Holder"), then the Issuer shall promptly after
discovery that such Person is a Non-Permitted Holder by the Issuer, the
Co-Issuer or the Trustee (and notice by the Trustee or the Co-Issuer to the
Issuer, if either of them makes the discovery), send notice (or procure that
notice is sent) to such Non-Permitted Holder demanding that such Non-Permitted
Holder transfer its interest to a Person that is not a Non-Permitted Holder
within 30 days of the date of such notice. If such Non-Permitted Holder fails to
so transfer its Note or interest therein, the Issuer shall have the right,
without further notice to the Non-Permitted Holder, to sell such Note or
interest therein to a purchaser selected by the Issuer that is not a
Non-Permitted Holder on such terms as the Issuer may choose. The Issuer, or the
Trustee acting on behalf of the Issuer, may select the purchaser by soliciting
one or more bids from one or more brokers or other market professionals that
regularly deal in securities similar to the Note, and selling such Note to the
highest such bidder. However, the Issuer or the Trustee may select a purchaser
by any other means determined by it in its sole discretion. The Holder of such
Note, the Non-Permitted Holder and each other Person in the chain of title from
the Holder to the Non-Permitted Holder, by its acceptance of an interest in the
Note, agrees to cooperate with the Issuer and the Trustee to effect such
transfers. The proceeds of such sale, net of any commissions, expenses and taxes
due in connection with such sale shall be remitted to the Non-Permitted Holder.
The terms and conditions of any sale under this Section 2.13(b) shall be
determined in the sole discretion of the Issuer, and the Issuer shall not be
liable to any Person having an interest in the Note sold as a result of any such
sale of exercise of such discretion.

          (c) Without limiting the foregoing, the Issuer and the Trustee on
behalf of the Bank agree, and the Bank shall cause the Custodial Securities
Intermediary, to take such different or additional action as the Trustee may
reasonably request in order to maintain the perfection and priority of the
security interest of the Trustee in the event of any change in applicable law or
regulation, including Articles 8 and 9 of the UCC and Treasury Regulations
governing transfers of interests in Government Items (it being understood that
the Trustee shall be entitled to rely upon an Opinion of Counsel, including an
Opinion of Counsel delivered in accordance with Section 3.1(d), as to the need
to file any financing statements or continuation statements, the dates by which
such filings are required to be made and the jurisdictions in which such filings
are required to be made).

          (d) Without limiting any of the foregoing,

          (i) in connection with each Grant of a Collateral Debt Security
     hereunder, the Issuer shall deliver (or cause to be delivered by the
     applicable Seller) to the Custodial Securities Intermediary (A) the
     original of any note (or a copy of such note together with a lost note
     affidavit and indemnity), certificate or other instrument constituting or
     evidencing such Collateral Debt Security and any other Underlying
     Instrument related to such Collateral Debt Security, the delivery of which
     is necessary in order to perfect the security interest of the Trustee in
     such Collateral Debt Security granted pursuant to this Indenture, (B)
     copies of the other Underlying Instruments then in possession of the Issuer
     and (C) any other agreements, documents, certificates or instruments not

     (i) to the extent such other agreements, documents, certificates or
     instruments are required to be delivered to the Issuer pursuant to the
     related Collateral Debt Securities Purchase Agreement;

          (ii) from time to time upon the request of the Trustee, Collateral
     Manager or Servicer, the Issuer shall deliver (or cause to be delivered) to
     the Custodial Securities Intermediary any Underlying Instrument in the
     possession of the Issuer and not previously delivered hereunder (including
     originals of Underlying Instruments not previously required to be delivered
     as originals) and as to which the Trustee, Collateral Manager or Servicer,
     as applicable, shall have reasonably determined to be necessary or
     appropriate for the administration of such Collateral Debt Security
     hereunder or under the Collateral Management Agreement or under the
     Servicing Agreement or for the protection of the security interest of the
     Trustee under this Indenture;

          (iii) in connection with any delivery of documents to the Custodial
     Securities Intermediary pursuant to clauses (i) and (ii) above, the Trustee
     shall deliver to the Collateral Manager and the Servicer, on behalf of the

     Collateral Manager or the Servicer of a duly completed Request for Release
     in the form of Exhibit N hereto, release to the Collateral Manager or the
     Servicer such of the Underlying Instruments then in its custody as the
     Collateral Manager or the Servicer reasonably so requests. By submission of
     any such Request for Release, the Collateral Manager or the Servicer, as
     applicable, shall be deemed to have represented and warranted that it has
     determined in accordance with the Collateral Manager Servicing Standard or
     the Servicing Standard set forth in the Servicing Agreement, as the case
     may be, that the requested release is necessary for the administration of
     such Collateral Debt Security hereunder or under the Collateral Management
     Agreement or under the Servicing Agreement or for the protection of the
     security interest of the Trustee under this Indenture. The Collateral
     Manager or the Servicer shall return to the Custodial Securities
     Intermediary each Underlying Instrument released from custody pursuant to
     this clause (iv) within 20 Business Days of receipt thereof (except such
     Underlying Instruments as are released in connection with a sale, exchange
     or other disposition, in each case only as permitted under this Indenture,
     of the related Collateral Debt Security that is consummated within such
     20-day period). Notwithstanding the foregoing provisions of this clause

     sale, exchange or other disposition of such Pledged Collateral Debt
     Security that is permitted in accordance with the terms of this Indenture,
     (2) presentation, collection, renewal or registration of transfer of such
     Collateral Debt Security or (3) in the case of any note, in connection with

     Indenture; and

          (v) to the extent the Collateral Manager deems necessary or advisable
     in accordance with the Collateral Manager Servicing Standard, the Issuer
     may, at the direction of the Collateral Manager (but only upon disclosure
     to, and with the prior consent of, the Advisory Committee), assign its
     right to purchase under a "buy/sell" arrangement in respect of a Collateral
     Debt Security to the Holder of the Preferred Shares or any Affiliate
     thereof.

existing as of the Closing Date) and each date on which an Asset is acquired
(only with respect to each Asset so acquired or arising after the Closing Date),
the Issuer represents and warrants as follows:

          (i) this Indenture creates a valid and continuing security interest
     (as defined in the UCC) in the Assets in favor of the Trustee for the

to be the Controlling Class hereunder, MBIA consents;

          (i) the Issuer loses its status as a Qualified REIT Subsidiary, unless
(A) within 90 days, the Issuer either (1) delivers an opinion of tax counsel of
nationally recognized standing in the United States experienced in such matters
to the effect that, notwithstanding the Issuer's loss of Qualified REIT
Subsidiary status, the Issuer is not, and has not been, an association (or

the Trustee, the Class A-1AR Note Agent, the Noteholders, each Rating Agency and
each Hedge Counterparty of the occurrence of such Event of Default.

          Section 5.2 Acceleration of Maturity; Rescission and Annulment.

          (a) If an Event of Default shall occur and be continuing (other than
the Events of Default specified in Section 5.1(f) or 5.1(g)), the Trustee may
(and shall at the direction of (x) in the case of an Event of Default specified
in Section 5.1(a), 5.1(b) or 5.1(j), so long as MBIA is deemed to be the
Controlling Class hereunder, MBIA or (y) in any other case, a Majority, by
outstanding principal amount, of each Class of Notes voting as a separate Class
(excluding any Notes owned by the Collateral Manager or any of its Affiliates or
by any accounts managed by them), declare the principal of and accrued and
unpaid interest on all the Notes to be immediately due and payable (and any such
acceleration shall automatically terminate the Reinvestment Period). If an Event
of Default described in Section 5.1(f) or 5.1(g) above occurs, such an
acceleration shall occur automatically and without any further action and any
such acceleration shall automatically terminate the Reinvestment Period. If the
Notes are accelerated, payments shall be made in the order and priority set
forth in Section 11.1(a) hereof. If an Event of Default shall occur and be
continuing, no Class A-1AR Draw may be made except with respect to Class A-1AR
Draws to be applied to fund Delayed Funding Amounts related to Delayed Draw Term
Loans; provided, however, that if an Event of Default specified in Section
5.1(f) or 5.1(g) occurs, the undrawn Class A-1AR Commitments shall terminate
automatically without need for further action. The Trustee will provide notice
of any such default to the Class A-1AR Note Agent. If the Notes are accelerated
(whether such acceleration is automatic or otherwise), the Issuer (or the
Collateral Manager on its behalf) shall take the actions described in Section
18.1(c) herein. Immediately following such draw, the Class A-1AR Commitments
shall terminate.

          (b) At any time after such a declaration of acceleration of Maturity
of the Notes has been made, and before a judgment or decree for payment of the
Money due has been obtained by the Trustee as hereinafter provided in this
Article 5, a Majority of each Class of Notes (voting as a separate Class), other
than with respect to an Event of Default specified in Section 5.1(d), 5.1(e),
5.1(h), 5.1(i) or 5.1(j), which may be rescinded only by MBIA so long as MBIA is
deemed to be the Controlling Class hereunder, by written notice to the Issuer,
the Co-Issuer, the Trustee and each Hedge Counterparty, may rescind and annul
such declaration and its consequences if:

          (i) the Issuer or the Co-Issuer has paid or deposited with the Trustee
     a sum sufficient to pay:

                    (A) all unpaid installments of interest on and principal of
               the Notes, and in the case of the Class A-1AR Notes, the Class
               A-1AR Commitment Fee, that would be due and payable hereunder if
               the Event of Default giving rise to such acceleration had not
               occurred;

                    (B) to the extent that payment of such interest is lawful,
               interest on the Class C Capitalized Interest at the Class C Rate,
               interest on the Class D Capitalized Interest at the Class D Rate,
               interest on the Class E


                                     -137-

<PAGE>

               Capitalized Interest at the Class E Rate, interest on the Class F
               Capitalized Interest at the Class F Rate, interest on the Class G
               Capitalized Interest at the Class G Rate and interest on the
               Class H Capitalized Interest at the Class H Rate;

                    (C) all unpaid taxes of the Issuer and the Co-Issuer,
               Company Administrative Expenses and other sums paid or advanced
               by or otherwise due and payable to the Trustee hereunder;

                    (D) with respect to each Hedge Agreement, any amount then
               due and payable thereunder;

                    (E) with respect to the Advancing Agent and the Backup
               Advancing Agent, any amount due and payable for unreimbursed
               Interest Advances and Reimbursement Interest;

                    (F) with respect to the Collateral Manager, any amount due
               and payable for unreimbursed Cure Advances; and

                    (G) with respect to the Collateral Management Agreement, any
               Senior Collateral Management Fee then due and any Company
               Administrative Expense due and payable to the Collateral Manager
               thereunder;

          (ii) the Hedge Agreements in effect immediately prior to the
     declaration of such acceleration shall remain in effect or, if such Hedge
     Agreements shall have become subject to early termination after the
     declaration of such acceleration, the Issuer shall have entered into a
     replacement Hedge Agreement for the terminated Hedge Agreement in
     accordance with Section 16.1; and

          (iii) the Trustee has determined that all Events of Default of which
     it has actual knowledge, other than the non-payment of the interest and
     principal on the Notes that have become due solely by such acceleration,
     have been cured and a Majority of the Controlling Class, by written notice
     to the Trustee and each Hedge Counterparty has agreed with such
     determination (which agreement shall not be unreasonably withheld or
     delayed) or waived as provided in Section 5.14.

          At any such time that the Trustee, subject to Section 5.2(b), shall
rescind and annul such declaration and its consequences as permitted
hereinabove, the Trustee shall preserve the Assets in accordance with the
provisions of Section 5.5 with respect to the Event of Default that gave rise to
such declaration; provided, however, that if such preservation of the Assets is
rescinded pursuant to Section 5.5, the Notes may be accelerated pursuant to the
first paragraph of this Section 5.2, notwithstanding any previous rescission and
annulment of a declaration of acceleration pursuant to this paragraph.

          No such rescission shall affect any subsequent Default or impair any
right consequent thereon. In addition, no such rescission shall affect any Hedge
Agreement if it has been terminated in accordance with its terms.


                                     -138-

          (c) Subject to Sections 5.4 and 5.5, a Majority of the Controlling
Class shall have the right to direct the Trustee in the conduct of any
Proceedings for any remedy available to the Trustee or in the sale of any or all
of the Assets; provided that (i) such direction will not conflict with any rule
of law or this Indenture; (ii) the Trustee may take any other action not
inconsistent with such direction; (iii) the Trustee determines that such action
will not involve it in liability (unless the Trustee has received satisfactory
indemnity or reasonable security against any such liability); and (iv) any
direction to undertake a sale of the Assets may be made only as described in
Section 5.17. Notwithstanding the foregoing, so long as MBIA is deemed to be the
Controlling Class hereunder, MBIA in all cases shall have the right to direct
the Trustee in the conduct of any proceedings or in the sale of any or all of
the Assets following an Event of Default specified in Section 5.1(j) or a
default with respect to the payment of principal of or interest on the Class A
Notes, which default also constitutes an Event of Default specified in Section
5.1(a) or 5.1(b), and a subsequent acceleration of the Notes but only if (i)
such direction will not conflict with any rule of law or this Indenture
(including the limitations described in Section 5.5 but excluding any
requirement requiring sufficient proceeds to pay in full the amounts then due
and unpaid on any of the Notes) and (ii) the Trustee determines that such action
will not involve it in liability (unless the Trustee has received satisfactory
indemnity or reasonable security against any such liability or expense). The
Trustee shall provide written notice of the receipt of such direction to each
Hedge Counterparty promptly after receipt thereof.

          (d) As security for the payment by the Issuer of the compensation and
expenses of the Trustee and any sums the Trustee may be entitled to receive as
indemnification by the Issuer, the Issuer hereby grants the Trustee a lien on
the Assets, which lien is senior to the lien of the Noteholders. The Trustee's
lien shall be subject to the Priority of Payments and exercisable by the Trustee
only if the Notes have been declared due and payable following an Event of
Default and such acceleration has not been rescinded or annulled.

          (e) A Majority of the Controlling Class, may, prior to the time a
judgment or decree for the payment of money due has been obtained by the
Trustee, waive any past Default on behalf of the holders of all the Notes and
its consequences in accordance with Section 5.14.

          (f) In determining whether the holders of the requisite percentage of
Notes have given any direction, notice or consent hereunder, (i) Notes owned by
the Issuer, the Co-Issuer or any Affiliate thereof shall be disregarded and
deemed not to be Outstanding and (ii) in relation to (x) any amendment or other
modification of, or assignment or termination of, any of the express rights or
obligations of the Collateral Manager under the Collateral Management Agreement
or this Indenture (including the exercise of any rights to remove the Collateral
Manager or terminate the Collateral Management Agreement or approve or object to
a replacement for the Collateral Manager except as specifically provided in the
Collateral Management Agreement with respect to the termination of the
Collateral Manager without cause and with respect to the replacement of the
Collateral Manager in instances where the Collateral Manager has not been
terminated for cause or where such replacement is not an Affiliate of the
Collateral Manager) and (y) the exercise by the Noteholders of their right, in
connection with certain Events of Default, to accelerate amounts due under the
Notes, Notes owned by the Collateral Manager or any of its Affiliates, or by any
accounts managed by them, shall be disregarded and deemed not to be Outstanding.
The Collateral Manager and its Affiliates shall


                                     -139-

<PAGE>

be entitled to vote Notes held by them, and by accounts managed by them, with
respect to all other matters other than those described in clause (ii).

          Section 5.3 Collection of Indebtedness and Suits for Enforcement by
Trustee.

Note for principal and interest or other payment with interest on the overdue

rate 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 and such
Noteholder and their respective agents and counsel.

          If the Issuer or the Co-Issuer 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 Issuer and the Co-Issuer or any other obligor upon
the Notes and collect the Monies adjudged or decreed to be payable in the manner
provided by law out of the Assets.

          If an Event of Default occurs and is continuing, the Trustee shall
proceed to protect and enforce its rights and the rights of the Noteholders by
such Proceedings (x) as directed by a Majority of the Controlling Class or (y)
in the absence of direction by a Majority of the Controlling Class, as deemed
most effectual by the Trustee. Such Proceedings shall be used 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.

          In the case where (x) there shall be pending Proceedings relative to

(y) a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken
possession of the Issuer or the Co-Issuer, or their respective property, or (z)

regardless of whether the principal of any Notes shall then be due and payable
as therein expressed or by declaration, or otherwise and regardless of whether
the Trustee shall have made any demand pursuant to the provisions of this
Section 5.3, the Trustee shall be entitled and empowered, by intervention in
such Proceedings or otherwise:


                                     -141-

          (a) to file and prove a claim or claims for the whole amount of
principal and interest and the Class A-1AR Commitment Fee owing and unpaid in
respect of the Notes 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 Noteholders allowed in any Proceedings relative to the Issuer, the Co-Issuer
or other obligor upon the Notes or to the creditors or property of the Issuer,
the Co-Issuer or such other obligor;

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

deliverable on any such claims, and to distribute all amounts received with
respect to the claims of the Noteholders 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 Noteholders to make payments to the Trustee,
and, in the event that the Trustee shall consent to the making of payments
directly to the Noteholders, 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
reasonable expenses and liabilities incurred, and all advances made, by the
Trustee and each predecessor Trustee except as a result of its own negligence,
willful misconduct or bad faith.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize, consent to, vote for, accept or adopt, on behalf of any Noteholder,
any plan of reorganization, arrangement, adjustment or composition affecting the
Notes or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Noteholder in any such Proceeding except, as
aforesaid, to vote for the election of a trustee in bankruptcy or similar
Person.

          All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes or the production thereof in any trial or other Proceedings
relative thereto, and any action or Proceedings instituted by the Trustee shall
be brought in its own name as trustee of an express trust, and any recovery of
judgment, shall be applied as set forth in Section 5.7.

Noteholders, the Trustee shall be held to represent all the Holders of the
Notes.

Trustee may not sell or liquidate the Assets or institute Proceedings in
furtherance thereof pursuant to this Section 5.3 unless the conditions specified
in Section 5.5(a) are met.

          Section 5.4 Remedies.

          (a) If an Event of Default has occurred and is continuing, and the
Notes have been declared due and payable and such declaration and its
consequences have not been rescinded and annulled, the Issuer and the Co-Issuer
agree that the Trustee may, after notice to the Noteholders and each Hedge
Counterparty, and shall, upon direction by a Majority of the Controlling Class,
to the extent permitted by applicable law, exercise one or more of the following
rights, privileges and remedies:

          (i) institute Proceedings for the collection of all amounts then
     payable on the Notes or otherwise payable under this Indenture (whether by
     declaration or otherwise), enforce any judgment obtained and collect from
     the Assets any Monies adjudged due;

          (ii) sell all or a portion of the Assets or rights of interest
     therein, at one or more public or private sales called and conducted in any
     manner permitted by law and in accordance with Section 5.17 hereof;

          (iii) institute Proceedings from time to time for the complete or
     partial foreclosure of this Indenture with respect to the Assets;

          (iv) exercise any remedies of a secured party under the UCC and take
     any other appropriate action to protect and enforce the rights and remedies
     of the Secured Parties hereunder; and

          (v) exercise any other rights and remedies that may be available at
     law or in equity;

provided, however, that the Trustee may not sell or liquidate the Assets or
institute Proceedings in furtherance thereof pursuant to this Section 5.4 unless
either of the conditions specified in Section 5.5(a) is met.

          The Trustee may, but need not, obtain and rely upon an opinion of an
Independent investment banking firm of national reputation with demonstrated
capabilities in structuring and distributing notes or certificates similar to
the Notes as to the feasibility of any action proposed to be taken in accordance
with this Section 5.4 and as to the sufficiency of the proceeds and other
amounts receivable with respect to the Assets to make the required payments of
principal of and interest on the Notes and other amounts payable hereunder,
which opinion shall be conclusive evidence as to such feasibility or
sufficiency.

          (b) If an Event of Default as described in Section 5.1(e) hereof shall
have occurred and be continuing, the Trustee may, and at the request of the
Holders of not less than 25% of the Aggregate Outstanding Amount of the
Controlling Class (which shall be deemed to be MBIA so long as it is the
Controlling Class hereunder) shall, institute a Proceeding solely to compel
performance of the covenant or agreement or to cure the representation or
warranty, the breach of which gave rise to the Event of Default under such
Section, and enforce any equitable decree or order arising from such Proceeding.

          (c) Upon any Sale, whether made under the power of sale hereby given
or by virtue of judicial proceedings, any Noteholder, Preferred Shareholder or
the Collateral Manager or any of its Affiliates may bid for and purchase the
Assets or any part thereof and, upon compliance with the terms of Sale, may
hold, retain, possess or dispose of such property in its or their own absolute
right without accountability; and any purchaser at any such Sale may, in paying
the purchase Money, turn in any of the Notes in lieu of Cash equal to the amount
which shall, upon distribution of the net proceeds of such sale, be payable on
the Notes so turned in by such Holder (taking into account the Class of such
Notes). Such Notes, in case the amounts so payable thereon shall be less than
the amount due thereon, shall be returned to the Holders thereof after proper
notation has been made thereon to show partial payment.

          Upon any Sale, whether made under the power of sale hereby given or by
virtue of judicial proceedings, the receipt of the Trustee or of the Officer
making a sale under judicial proceedings shall be a sufficient discharge to the
purchaser or purchasers at any sale for its or their purchase Money and such
purchaser or purchasers shall not be obliged to see to the application thereof.

          Any such Sale, whether under any power of sale hereby given or by
virtue of judicial proceedings, shall (x) bind the Issuer, the Co-Issuer, the
Trustee, the Noteholders and the Preferred Shareholders, shall operate to divest
all right, title and interest whatsoever, either at law or in equity, of each of
them in and to the property sold and (y) be a perpetual bar, both at law and in
equity, against each of them and their successors and assigns, and against any
and all Persons claiming through or under them.

          (d) Notwithstanding any other provision of this Indenture or any other
Transaction Document, none of the Advancing Agent, the Trustee or any other
Secured Party, any other party to any Transaction Document or third party
beneficiary of this Indenture may, prior to the date which is one year and one
day, or, if longer, the applicable preference period then in effect (including
any period established pursuant to the laws of the Cayman Islands) after the
payment in full of all Notes, institute against, or join any other Person in
instituting against, the Issuer or the Co-Issuer any bankruptcy, reorganization,
arrangement, insolvency, moratorium or liquidation proceedings, or other
proceedings under federal or State bankruptcy or similar laws of any
jurisdiction. Nothing in this Section 5.4 shall preclude, or be deemed to stop,
the Advancing Agent, the Trustee or any other Secured Party or any other party
to any Transaction Document (i) from taking any action prior to the expiration
of the aforementioned one year and one day period, or, if longer, the applicable
preference period then in effect (including any period established pursuant to
the laws of the Cayman Islands) period in (A) any case or proceeding voluntarily
filed or commenced by the Issuer or the Co-Issuer or (B) any involuntary
insolvency proceeding filed or commenced by a Person other than the Trustee or
any other Secured Party or any other party to any Transaction Document, or (ii)
from commencing against the Issuer or the Co-Issuer or any of their respective
properties any legal action which is not a bankruptcy, reorganization,
arrangement, insolvency, moratorium or liquidation proceeding.

          Section 5.5 Preservation of Assets.

          (a) Notwithstanding anything to the contrary herein, if an Event of
Default shall have occurred and be continuing when any of the Notes are
Outstanding, the Trustee shall


                                     -144-

<PAGE>

retain the Assets securing the Notes, collect and cause the collection of the
proceeds thereof and make and apply all payments and deposits and maintain all
accounts in respect of the Assets and the Notes in accordance with the Priority
of Payments and the provisions of Articles 10, 12 and 13 unless either:

          (i) in the case of an Event of Default specified in Section 5.1(j) or
     a default with respect to the payment of principal of or interest on the
     Class A Notes, which default also constitutes an Event of Default specified
     in Section 5.1(a) or 5.1(b), so long as MBIA is the Controlling Class under
     this Indenture, MBIA directs the Trustee to sell or otherwise liquidate the
     Assets;

          (ii) the Trustee, pursuant to Section 5.5(c), determines that the
     anticipated proceeds of a sale or liquidation of the Assets (after
     deducting the reasonable expenses of such sale or liquidation) would be
     sufficient to discharge in full the amounts then due and unpaid on the
     Notes (including the Class A-1AR Commitment Fee), Company Administrative
     Expenses due and payable pursuant to clauses (3) and (26) of Section
     11.1(a)(i) and clauses (1) and (10) of Section 11.1(a)(ii), the Senior
     Collateral Management Fees due and payable pursuant to clause (4) of
     Section 11.1(a)(i), the Subordinate Collateral Management Fees due and
     payable pursuant to clause (27) of Section 11.1(a)(i), any amounts due and
     unpaid to each Hedge Counterparty, including without limitation, any
     payments (however described) due and payable by the Issuer under each Hedge
     Agreement upon a termination of such Hedge Agreement (including any
     interest that may accrue thereon) and amounts due and payable to the
     Advancing Agent and the Backup Advancing Agent, in respect of unreimbursed
     Interest Advances and Reimbursement Interest, and the holders of a Majority
     of the Controlling Class (which shall be deemed to be MBIA so long as it is
     the Controlling Class hereunder) agrees with such determination; or

          (iii) the Holders of at least 66- 2/3% of the Aggregate Outstanding
     Amount of each Class of Notes (each voting as a separate Class) (and each
     Hedge Counterparty, unless each shall be paid in full the amounts due and
     unpaid, including, without limitation, any payments (however described) due
     and payable by the Issuer under each Hedge Agreement upon a termination of
     such Hedge Agreement (including any interest that may accrue thereon)),
     direct, subject to the provisions of this Indenture, the sale and
     liquidation of the Assets.

          The Trustee shall give written notice of the retention of the Assets
to the Issuer, the Co-Issuer, the Collateral Manager, each Hedge Counterparty
and the Rating Agencies. So long as such Event of Default is continuing, any
such retention pursuant to this Section 5.5(a) may be rescinded at any time when
the conditions specified in clause (i) or (ii) above exist.

          (b) Nothing contained in Section 5.5(a) shall be construed to require
the Trustee to sell the Assets securing the Notes if the conditions set forth in
Section 5.5(a) are not satisfied. Nothing contained in Section 5.5(a) shall be
construed to require the Trustee to preserve the Assets securing the Notes if
prohibited by applicable law.


                                     -145-
<PAGE>

          (c) To assist the Trustee in determining whether the condition
specified in Section 5.5(a)(i) exists, the Collateral Manager shall obtain bid
prices with respect to each Pledged Collateral Debt Security from two dealers
(Independent of the Collateral Manager and any of its Affiliates) at the time
making a market in such Pledged Collateral Debt Securities (or, if there is only
one market maker, then the Collateral Manager shall obtain a bid price from that
market maker or, if no market maker, from a pricing service). The Collateral
Manager shall compute the anticipated proceeds of sale or liquidation on the
basis of the lowest of such bid prices for each such Pledged Collateral Debt
Security and provide the Trustee with the results thereof. For the purposes of
determining issues relating to the Market Value of any Pledged Collateral Debt
Security and the execution of a sale or other liquidation thereof, the Trustee
may, but need not, retain at the expense of the Issuer and rely on an opinion of
an Independent investment banking firm of national reputation in connection with
a determination (notwithstanding that such opinion will not be the basis for
such determination) as to whether the condition specified in Section 5.5(a)(i)
exists.

          The Trustee shall promptly deliver to the Noteholders and each Hedge
Counterparty a report stating the results of any determination required to be
made pursuant to Section 5.5(a)(i). If requested by a Majority of the
Controlling Class, the Trustee shall make the determinations required by Section
5.5(a)(i) within 30 days of such request.

          Section 5.6 Trustee May Enforce Claims Without Possession of Notes.

          All rights of action and claims under this Indenture or under any of
the Notes may be prosecuted and enforced by the Trustee without the possession
of any of the Notes or the production thereof in any trial or other Proceeding
relating thereto, and any such action or Proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust. Any recovery of
judgment in respect of the Notes shall be applied as set forth in Section 5.7
hereof.

          In any Proceedings brought by the Trustee (and in any Proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) in respect of the Notes, the Trustee shall be held to
represent all the Holders of the Notes.

          Section 5.7 Application of Money Collected.

          Any Money collected by the Trustee with respect to the Notes pursuant
to this Article 5 and any Money that may then be held or thereafter received by
the Trustee with respect to the Notes hereunder shall be applied subject to
Section 13.1 hereof and in accordance with the Priority of Payments set forth in
Section 11.1 hereof, at the date or dates fixed by the Trustee.

          Section 5.8 Limitation on Suits.

          No Holder of any Notes 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:

          (a) such Holder has previously given to the Trustee written notice of
an Event of Default;


                                      -146-

<PAGE>

          (b) except as otherwise provided in Section 5.9 hereof, the Holders of
at least 25% of the then Aggregate Outstanding Amount of the Controlling Class
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 and such
Holders have offered to the Trustee reasonable indemnity against the costs,
expenses and liabilities to be incurred in compliance with such request;

          (c) the Trustee for 30 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such Proceeding; and

          (d) no direction inconsistent with such written request has been given
to the Trustee during such 30-day period by a Majority of the Controlling Class;
it being understood and intended that no one or more Holders of Notes shall have
any right in any manner whatsoever by virtue of, or by availing of, any
provision of this Indenture to affect, disturb or prejudice the rights of any
other Holders of Notes of the same Class or to obtain or to seek to obtain
priority or preference over any other Holders of the Notes of the same Class 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 Notes of the same
Class subject to and in accordance with Section 13.1 hereof and the Priority of
Payments.

          In the event the Trustee shall receive conflicting or inconsistent
requests and indemnity from two or more groups of Holders of the Controlling
Class, each representing less than a Majority of the Controlling Class, the
Trustee in its sole discretion may determine what action, if any, shall be
taken, notwithstanding any other provisions of this Indenture.

          Section 5.9 Unconditional Rights of Noteholders to Receive Principal,
Interest and the Class A-1AR Commitment Fee.

          Notwithstanding any other provision in this Indenture (except for
Section 2.7(l) and 2.7(u)), the Holder of any Class of Note shall have the
right, which is absolute and unconditional, to receive payment of the principal
of and interest (and the Class A-1AR Commitment Fee, as applicable) on such
Class of Note as such principal, interest (and the Class A-1AR Commitment Fee,
as applicable) and other amounts become due and payable in accordance with the
Priority of Payments and Section 13.1, and, subject to the provisions of
Sections 5.4 and 5.8 to institute Proceedings for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder; provided, however, that the right of such Holder to institute
proceedings for the enforcement of any such payment shall not be subject to the
25% threshold requirement set forth in Section 5.8(b).

          Section 5.10 Restoration of Rights and Remedies.

          If the Trustee or any Noteholder 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 adversely to
the Trustee or to such Noteholder, then (and in every such case) the Issuer, the
Co-Issuer, the Trustee, and the Noteholder shall, subject to any determination
in such Proceeding, be restored severally and respectively to their former
positions


                                      -147-

<PAGE>

hereunder, and thereafter all rights and remedies of the Trustee and the
Noteholders shall continue as though no such Proceeding had been instituted.

          Section 5.11 Rights and Remedies Cumulative.

          No right or remedy herein conferred upon or reserved to the Trustee or
to the Noteholders 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 5.12 Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Noteholder 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 or a waiver of a subsequent Event of Default. Every right
and remedy given by this Article 5 or by law to the Trustee, or to the
Noteholders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee, or by the Noteholders, as the case may be.

          Section 5.13 Control by the Controlling Class.

          Notwithstanding any other provision of this Indenture, if an Event of
Default shall have occurred and be continuing when any of the Notes are
Outstanding, a Majority of the Controlling Class (which shall be deemed to be
MBIA so long as it is the Controlling Class hereunder) shall have the right to
cause the institution of and direct the time, method and place of conducting any
Proceeding for any remedy available to the Trustee for exercising any trust,
right, remedy or power conferred on the Trustee in respect of the Notes;
provided that:

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

          (b) 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 6.1, the Trustee need not take any action that it determines might
involve it in liability (unless the Trustee has received satisfactory indemnity
against such liability as set forth below);

          (c) the Trustee shall have been provided with indemnity satisfactory
to it; and

          (d) any direction to the Trustee to undertake a Sale of the Assets
shall be by the Holders of Notes secured thereby representing at least 66 2/3%
of the Aggregate Outstanding Amount of each Class of Notes or to the extent
required pursuant to Section 5.5, MBIA, so long as it is deemed to be the
Controlling Class hereunder.

<PAGE>

          Section 5.14 Waiver of Past Defaults.

          Prior to the time a judgment or decree for payment of the Money due
has been obtained by the Trustee, as provided in this Article 5, so long as MBIA
is deemed to be the Controlling Class hereunder, MBIA may (with the consent of
the Hedge Counterparty if such Hedge Counterparty is materially and adversely
affected by the default with respect to the Notes), waive any Event of Default
specified in Section 5.1(d), 5.1(e), 5.1(h), 5.1(i), or 5.1(j) with respect to
the Notes and its consequences; thereafter, a Majority of each and every Class
of Notes (voting as a separate Class) may, on behalf of the Holders of all the
Notes, waive any past Default in respect of the Notes and its consequences,
except a Default:

          (a) in the payment of principal of any Note;

          (b) in the payment of interest in respect of the Controlling Class;

          (c) in the payment of the Class A-1AR Commitment Fee in respect of the
Class A-1AR Notes;

          (d) in respect of a covenant or provision hereof that, under Section
8.2, cannot be modified or amended without the waiver or consent of the Holder
of each Outstanding Note and each Hedge Counterparty adversely affected thereby;

          (e) in respect of any covenant or provision hereof for the individual
protection or benefit of the Trustee, without the Trustee's express written
consent thereto; or

          (f) a default that also materially adversely affects a Hedge
Counterparty unless such Hedge Counterparty also agrees to such default.

          In the case of any such waiver, the Issuer, the Co-Issuer, the
Trustee, and the Holders of the Notes shall be restored to their respective
former positions and rights hereunder, but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereto. The Trustee
shall promptly give written notice of any such waiver to the Collateral Manager,
each Noteholder and each Hedge Counterparty.

          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 thereto.

          Section 5.15 Undertaking for Costs.

          All parties to this Indenture agree, and each Holder of any Note by
its 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 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


                                      -149-

<PAGE>

litigant; but the provisions of this Section 5.15 shall not apply to any suit
instituted by (x) the Trustee, (y) any Noteholder, or group of Noteholders,
holding in the aggregate more than 10% of the Aggregate Outstanding Amount of
the Controlling Class or (z) any Noteholder for the enforcement of the payment
of the principal of or interest, or the Class A-1AR Commitment Fee, as
applicable, on any Note or any other amount payable hereunder on or after the
Stated Maturity (or, in the case of redemption, on or after the applicable
Redemption Date).

          Section 5.16 Waiver of Stay or Extension Laws.

          Each of the Issuer and the Co-Issuer covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, 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 (including
but not limited to filing a voluntary petition under Chapter 11 of the
Bankruptcy Code and by the voluntary commencement of a proceeding or the filing
of a petition seeking winding up, liquidation, reorganization or other relief
under any bankruptcy, insolvency, reorganization, moratorium, receivership,
conservatorship or other similar laws now or hereafter in effect), which may
affect the covenants, the performance of or any remedies under this Indenture;
and each of the Issuer and the Co-Issuer (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 5.17 Sale of Assets.

          (a) The power to effect any sale (a "Sale") of any portion of the
Assets pursuant to Sections 5.4 and 5.5 hereof shall not be exhausted by any one
or more Sales as to any portion of such Assets remaining unsold, but shall
continue unimpaired until all amounts secured by the Assets shall have been paid
or if there are insufficient proceeds to pay such amount until the entire Assets
shall have been sold. The Trustee may, upon notice to the Securityholders and
each Hedge Counterparty, and shall, upon direction of a Majority of the
Controlling Class, from time to time postpone any Sale by public announcement
made at the time and place of such Sale; provided, however, that if the Sale is
rescheduled for a date more than three Business Days after the date of the
determination by the Trustee pursuant to Section 5.5(a)(i) hereof, such Sale
shall not occur unless and until the Trustee has again made the determination
required by Section 5.5(a)(i) hereof. The Trustee hereby expressly waives its
rights to any amount fixed by law as compensation for any Sale; provided that
the Trustee shall be authorized to deduct the reasonable costs, charges and
expenses incurred by it in connection with such Sale from the proceeds thereof
notwithstanding the provisions of Section 6.7 hereof.

          (b) The Trustee may bid for and acquire any portion of the Assets in
connection with a public Sale thereof, and may pay all or part of the purchase
price by crediting against amounts owing on the Notes or other amounts secured
by the Assets, all or part of the net proceeds of such Sale after deducting the
reasonable costs, charges and expenses incurred by the Trustee in connection
with such Sale notwithstanding the provisions of Section 6.7 hereof. The Notes
need not be produced in order to complete any such Sale, or in order for the net
proceeds of such Sale to be credited against amounts owing on the Notes. The
Trustee may hold, lease,


                                      -150-

<PAGE>

operate, manage or otherwise deal with any property so acquired in any manner
permitted by law in accordance with this Indenture.

          (c) If any portion of the Assets consists of securities issued without
registration under the Securities Act ("Unregistered Securities"), the Trustee
may seek an Opinion of Counsel, or, if no such Opinion of Counsel can be
obtained and with the consent of a Majority of the Controlling Class, seek a no
action position from the SEC or any other relevant federal or State regulatory
authorities, regarding the legality of a public or private Sale of such
Unregistered Securities. In no event shall the Trustee be required to register
Unregistered Securities under the Securities Act.

          (d) The Trustee shall execute and deliver an appropriate instrument of
conveyance transferring its interest in any portion of the Assets in connection
with a Sale thereof. In addition, the Trustee is hereby irrevocably appointed
the agent and attorney in fact of the Issuer to transfer and convey its interest
in any portion of the Assets in connection with a Sale thereof, and to take all
action necessary to effect such Sale. No purchaser or transferee at such a Sale
shall be bound to ascertain the Trustee's authority, to inquire into the
satisfaction of any conditions precedent or to see to the application of any
Monies.

          (e) In the event of any Sale of the Assets pursuant to Section 5.4 or
Section 5.5, payments shall be made in the order and priority set forth in
Section 11.1(a) in the same manner as if the Notes had been accelerated.

          Section 5.18 Action on the Notes.

          The Trustee's right to seek and recover judgment on the Notes or under
this Indenture shall not be affected by the application for or obtaining of any
other relief under or with respect to this Indenture. Neither the lien of this
Indenture nor any rights or remedies of the Trustee or the Noteholders shall be
impaired by the recovery of any judgment by the Trustee against the Issuer or
the Co-Issuer or by the levy of any execution under such judgment upon any
portion of the Assets or upon any of the assets of the Issuer or the Co-Issuer.

                                    ARTICLE 6

                                   THE TRUSTEE

          Section 6.1 Certain Duties and Responsibilities.

          (a) Except during the continuance of an Event of Default:

          (i) the Trustee undertakes to perform such duties and only such duties
     as are set forth in this Indenture, and no implied covenants or obligations
     shall be read into this Indenture against the Trustee; and

          (ii) in the absence of manifest error, or bad faith on its part, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming


                                      -151-

<PAGE>

     to the requirements of this Indenture; provided, however, that in the case
     of any such certificates or opinions which by any provision hereof are
     specifically required to be furnished to the Trustee, the Trustee shall be
     under a duty to examine the same to determine whether or not they
     substantially conform to the requirements of this Indenture and shall
     promptly, but in any event within three Business Days in the case of an
     Officer's Certificate furnished by the Collateral Manager, notify the party
     delivering the same if such certificate or opinion does not conform. If a
     corrected form shall not have been delivered to the Trustee within 15 days
     after such notice from the Trustee, the Trustee shall so notify the
     Noteholders.

          (b) In case an Event of Default known to the Trustee has occurred and
is continuing, the Trustee shall, prior to the receipt of directions, if any,
from a Majority of the Controlling Class (or other Noteholders to the extent
provided in Article 5 hereof)), exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

          (c) If, in performing its duties under this Indenture, the Trustee is
required to decide between alternative courses of action, the Trustee may
request written instructions from the Collateral Manager as to courses of action
desired by it. If the Trustee does not receive such instructions within two
Business Days after it has requested them, it may, but shall be under no duty
to, take or refrain from taking such action. The Trustee shall act in accordance
with instructions received after such two-Business Day period except to the
extent it has already taken, or committed itself to take, action inconsistent
with such instructions. The Trustee shall be entitled to rely on the advice of
legal counsel and Independent accountants in performing its duties hereunder and
be deemed to have acted in good faith if it acts in accordance with such advice.

          (d) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

          (i) this subsection shall not be construed to limit the effect of
     Section 6.1(a);

          (ii) the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer, unless it shall be proven that the Trustee
     was negligent in ascertaining the pertinent facts;

          (iii) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Issuer in accordance with this Indenture and/or the Controlling
     Class relating to the time, method and place of conducting any Proceeding
     for any remedy available to the Trustee in respect of any Note or
     exercising any trust or power conferred upon the Trustee under this
     Indenture;

          (iv) no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers contemplated hereunder,


                                      -152-

<PAGE>

     if it shall have reasonable grounds for believing that repayment of such
     funds or adequate indemnity against such risk or liability is not
     reasonably assured to it (if the amount of such funds or risk or liability
     does not exceed the amount payable to the Trustee pursuant to Section
     11.1(a)(i)(3) and Section 11.1(a)(ii)(1) net of the amounts specified in
     Section 6.7(a)(i), the Trustee shall be deemed to be reasonably assured of
     such repayment) unless such risk or liability relates to its ordinary
     services under this Indenture, except where this Indenture provides
     otherwise; and

          (v) the Trustee shall not be liable to the Noteholders for any action
     taken or omitted by it at the direction of the Issuer, the Co-Issuer, the
     Collateral Manager, the Controlling Class and/or a Noteholder under
     circumstances in which such direction is required or permitted by the terms
     of this Indenture.

          (e) For all purposes under this Indenture, the Trustee shall not be
deemed to have notice or knowledge of any Event of Default described in Section
5.1(d), 5.1(f), 5.1(g), 5.1(h) or 5.1(i) or any Default described in Section
5.1(e) unless a Trust Officer assigned to and working in the Corporate Trust
Office has actual knowledge thereof or unless written notice of any event which
is in fact such an Event of Default or Default is received by the Trustee at the
Corporate Trust Office, and such notice references, as applicable, the Notes
generally, the Issuer, the Assets or this Indenture. For purposes of determining
the Trustee's responsibility and liability hereunder, whenever reference is made
in this Indenture to such an Event of Default or a Default, such reference shall
be construed to refer only to such an Event of Default or Default of which the
Trustee is deemed to have notice as described in this Section 6.1.

          (f) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of
Sections 6.1(a), (b), (c), (d) and (e).

account, records, reports and other papers of the Trustee relating to the Notes,
to make copies and extracts therefrom (the reasonable out-of-pocket expenses
incurred in making any such copies or extracts to be reimbursed to the Trustee
by such Person) and to discuss the Trustee's actions, as such actions relate to
the Trustee's duties with respect to the Notes, with the Trustee's officers and
employees responsible for carrying out the Trustee's duties with respect to the
Notes.

          Section 6.2 Notice of Default.

          Promptly (and in no event later than three Business Days) after the
occurrence of any Default known to the Trustee or after any declaration of
acceleration has been made or delivered to the Trustee pursuant to Section 5.2,
the Trustee shall transmit by mail to the Collateral Manager, the Class A-1AR
Note Agent, the Irish Paying Agent (for so long as any Notes are listed on the
Irish Stock Exchange), each Hedge Counterparty, each Rating Agency (for so long
as any Class of Notes is Outstanding and rated by such Rating Agency), so long
as MBIA is deemed to be the Controlling Class hereunder, MBIA, and to all
Holders of Notes as


                                      -153-

their names and addresses appear on the Notes Register, notice of all Defaults
hereunder known to the Trustee, unless such Default shall have been cured or
waived.

          Except as otherwise provided in Section 6.1:

          (a) the Trustee may rely and shall be protected in acting or

received by it from the Collateral Manager (or from any selling institution,
agent bank, trustee or similar source) with respect to the Collateral Debt
Securities; and

          (k) to the extent any defined term hereunder, or any calculation
required to be made or determined by the Trustee hereunder, is dependent upon or
defined by reference to generally accepted accounting principles in the United
States in effect from time to time ("GAAP"), the Trustee shall be entitled to
request and receive (and rely upon) instruction from the Issuer or the

          Section 6.5 May Hold Notes.

          The Trustee, the Paying Agent, the Notes Registrar or any other agent
of the Issuer or the Co-Issuer, in its individual or any other capacity, may

and income or other gain actually received by the Trustee on Eligible
Investments.

          Section 6.7 Compensation and Reimbursement.

          (a) The Issuer agrees:

          (i) to pay the Trustee on each Payment Date in accordance with the
     Priority of Payments 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);

          (ii) except as otherwise expressly provided herein, to reimburse the
     Trustee (subject to any written agreement between the Issuer and the
     Trustee) in a timely manner upon its request for all reasonable expenses,
     disbursements and advances (except as otherwise provided herein with
     respect to Interest Advances) incurred or made by the Trustee in accordance
     with any provision of this Indenture (including securities transaction
     charges to the extent not waived due to the Trustee's receipt of payments
     from a financial institution with respect to certain Eligible Investments,
     as specified by the Collateral Manager and the reasonable compensation and
     expenses and disbursements of its agents and legal counsel and of any
     accounting firm or investment banking firm employed by the Trustee pursuant
     to Section 5.4, 5.5, 10.11 or 10.13 hereof, except any such expense,
     disbursement or advance as may be attributable to its negligence, willful
     misconduct or bad faith);

          (iii) to indemnify the Trustee and its Officers, directors, employees

     administration of this trust, including the costs and expenses of defending
     themselves against any claim or liability in connection with the exercise
     or performance of any of their powers or duties hereunder; and

                                      -156-

<PAGE>

          (b) The Issuer may remit payment for such fees and expenses to the
Trustee or, in the absence thereof, the Trustee may from time to time deduct
payment of its fees and expenses hereunder from Monies on deposit in the Payment
Account in accordance with the Priority of Payments.

          (c) The Trustee, in its capacity as Trustee, Paying Agent, Calculation
Agent, Transfer Agent, Custodial Securities Intermediary, Backup Advancing Agent
and Notes Registrar, hereby agrees not to cause the filing of a petition in
bankruptcy against the Issuer or the Co-Issuer until at least one year and one
day (or, if longer, the applicable preference period then in effect) after the
payment in full of all Notes issued under this Indenture. This provision shall
survive termination of this Indenture.

          (d) The Trustee agrees that the payment of all amounts to which it is
entitled pursuant to Sections 6.7(a)(i), (a)(ii), (a)(iii) and (a)(iv) shall be
subject to the Priority of Payments, shall be payable only to the extent funds
are available in accordance with such Priority of Payments, shall be payable
solely from the Assets and following realization of the Assets, any such claims
of the Trustee against the Issuer, and all obligations of the Issuer, shall be
extinguished. The Trustee will have a lien upon the Assets to secure the payment
of such payments to it in accordance with the Priority of Payments; provided
that the Trustee shall not institute any proceeding for enforcement of such lien
except in connection with an action taken pursuant to Section 5.3 hereof for
enforcement of the lien of this Indenture for the benefit of the Noteholders.

          Fees shall be accrued on the actual number of days in the related
Interest Accrual Period. The Trustee shall receive amounts pursuant to this
Section 6.7 and Section 11.1(a) only to the extent that such payment is made in
accordance with the Priority of Payments and the failure to pay such amounts to
the Trustee will not, by itself, constitute an Event of Default. Subject to
Section 6.9, the Trustee shall continue to serve as Trustee under this Indenture
notwithstanding the fact that the Trustee shall not have received amounts due to
it hereunder. No direction by a Majority of the Controlling Class shall affect
the right of the Trustee to collect amounts owed to it under this Indenture.

          If on any Payment Date when any amount shall be payable to the Trustee
pursuant to this Indenture is not paid because there are insufficient funds
available for the payment thereof, all or any portion of such amount not so paid
shall be deferred and payable on any later Payment Date on which a fee shall be
payable and sufficient funds are available therefor in accordance with the
Priority of Payments.

          Section 6.8 Corporate Trustee Required; Eligibility.

          There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America or of any State thereof, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$200,000,000, subject to supervision or examination by federal or State
authority, having a rating of at least "A2" by Moody's, a rating of at least
"BBB" by Fitch and a long-term senior unsecured debt rating of at least "A+" and
a short-term debt rating of at least "A-1" by S&P and having an office within
the United States. If such corporation publishes


                                      -157-

<PAGE>

reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 6.8, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 6.8, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article 6.

          Section 6.9 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 6 shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.10.

          (b) The Trustee may resign at any time by giving written notice
thereof to the Issuer, the Co-Issuer, the Collateral Manager, the Class A-1AR
Note Agent, each Hedge Counterparty, the Noteholders, each Rating Agency and so
long as MBIA is deemed to be the Controlling Class hereunder, MBIA. Upon
receiving such notice of resignation, the Issuer and the Co-Issuer shall
promptly appoint a successor trustee or trustees by written instrument, in
duplicate, executed by an Authorized Officer of the Issuer and an Authorized
Officer of the Co-Issuer, one copy of which shall be delivered to the Trustee so
resigning and one copy to the successor Trustee or Trustees, together with a
copy to each Noteholder, the Class A-1AR Note Agent, each Hedge Counterparty and
the Collateral Manager; provided that such successor Trustee shall be appointed
only upon the written consent of a Majority of the Notes (or if there are no
Notes Outstanding, a Majority of the Preferred Shares) or, at any time when an
Event of Default shall have occurred and be continuing or when a successor
Trustee has been appointed pursuant to Section 6.10, by Act of a Majority of the
Controlling Class. If no successor Trustee shall have been appointed and an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee, the Controlling Class of Notes or any Holder of a Note, on
behalf of himself and all others similarly situated, may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

          (c) The Trustee may be removed (i) at any time by Act of at least
66-2/3% of the Notes (or if there are no Notes Outstanding, a Majority of the
Preferred Shares); provided that, so long as MBIA is deemed to be the
Controlling Class hereunder, MBIA consents to such removal or (ii) at any time
when an Event of Default shall have occurred and be continuing or when a
successor Trustee has been appointed pursuant to Section 6.10, by Act of a
Majority of the Controlling Class, in each case, upon written notice delivered
to the Trustee and to the Issuer and the Co-Issuer.

          (d) If at any time:

          (i) the Trustee shall cease to be eligible under Section 6.8 and shall
     fail to resign after written request therefor by the Issuer, the Co-Issuer,
     or by any Holder; or

          (ii) the Trustee shall become incapable of acting or there shall be
     instituted any proceeding pursuant to which it could be adjudged as
     bankrupt or insolvent or a


                                      -158-

<PAGE>

     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 (subject to Section 6.9(a)), (a) the Issuer or the
Co-Issuer, by Issuer Order, subject to the written consent of each Hedge
Counterparty, may remove the Trustee or (b) subject to Section 5.15, a Majority
of the Controlling Class or any Holder 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 reason,
the Issuer and the Co-Issuer, by Issuer Order, subject to the written consent of
each Hedge Counterparty and the Collateral Manager, shall promptly appoint a
successor Trustee. If the Issuer and the Co-Issuer shall fail to appoint a
successor Trustee within 60 days after such resignation, removal or incapability
or the occurrence of such vacancy, a successor Trustee may be appointed by Act
of a Majority of the Controlling Class delivered to the Issuer, the Co-Issuer,
the Collateral Manager and the retiring Trustee. The successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede any successor Trustee proposed by the Issuer and
the Co-Issuer. If no successor Trustee shall have been so appointed by the
Issuer and the Co-Issuer or a Majority of the Controlling Class and shall have
accepted appointment in the manner hereinafter provided, subject to Section
5.15, each Hedge Counterparty, the Controlling Class or any Holder may, on
behalf of itself or himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

          (f) The Issuer and the Co-Issuer shall give prompt 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 each Rating Agency, each Hedge Counterparty, the Preferred Shares
Paying Agent, the Collateral Manager and to the Holders of the Notes as their
names and addresses appear in the Notes Register. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office. If
the Issuer or the Co-Issuer fail to mail such notice within ten days after
acceptance of appointment by the successor Trustee, the successor Trustee shall
cause such notice to be given at the expense of the Issuer or the Co-Issuer, as
the case may be.

          Section 6.10 Acceptance of Appointment by Successor.

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Issuer, the Co-Issuer, the Class A-1AR Note Agent, each Hedge
Counterparty, the Collateral Manager, the Servicer, so long as MBIA is deemed to
be the Controlling Class hereunder, MBIA, and the retiring Trustee an instrument
accepting such appointment. Upon delivery of the required instruments, the
resignation or removal of the retiring Trustee 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 of the
retiring Trustee; but, on request of the Issuer and the Co-Issuer or a Majority
of the Controlling Class or the Collateral Manager 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


                                      -159-

<PAGE>

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 6.7(d). Upon request of any such successor Trustee, the
Issuer and the Co-Issuer 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.

          No successor Trustee shall accept its appointment unless (a) at the
time of such acceptance such successor shall be qualified and eligible under
this Article 6, (b) such successor shall have long term debt rated within the
four highest rating categories by each Rating Agency, and (c) the Rating Agency
Condition is satisfied and, so long as MBIA is deemed to be the Controlling
Class hereunder, MBIA consents with respect thereto.

          Section 6.11 Merger, Conversion, Consolidation or Succession to
Business of Trustee.

          Any corporation or banking association into which the Trustee may be
merged or converted or with which it may be consolidated, or any corporation or
banking association 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 6, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case
any of the Notes 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 Notes so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Notes.

          Section 6.12 Co-Trustees and Separate Trustee.

          At any time or times, including for the purpose of meeting the legal
requirements of any jurisdiction in which any part of the Assets may at the time
be located, the Issuer, the Co-Issuer and the Trustee shall have power to
appoint, one or more Persons to act as co-trustee jointly with the Trustee of
all or any part of the Assets, with the power to file such proofs of claim and
take such other actions pursuant to Section 5.6 herein and to make such claims
and enforce such rights of action on behalf of the Holders of the Notes as such
Holders themselves may have the right to do, subject to the other provisions of
this Section 6.12.

          Each of the Issuer and the Co-Issuer shall join with the Trustee in
the execution, delivery and performance of all instruments and agreements
necessary or proper to appoint a co-trustee. If the Issuer and the Co-Issuer do
not both join in such appointment within 15 days after the receipt by them of a
request to do so, the Trustee shall have power to make such appointment.

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


                                      -160-

<PAGE>

by the Issuer or the Co-Issuer, as the case may be. The Issuer agrees to pay
(but only from and to the extent of the Assets) to the extent funds are
available therefor under clauses (3) and (26) of Section 11.1(a)(i), for any
reasonable fees and expenses in connection with such appointment.

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

          (a) the Notes 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;

          (b) the rights, powers, duties and obligations hereby conferred or
imposed upon the Trustee in respect of any property covered by the appointment
of a co-trustee shall be conferred or imposed upon and exercised or performed by
the Trustee or by the Trustee and such co-trustee jointly in the case of the
appointment of a co-trustee as shall be provided in the instrument appointing
such co-trustee, except to the extent that under any law of any jurisdiction in
which any particular act is to be performed, the Trustee shall be incompetent or
unqualified to perform such act, in which event such rights, powers, duties and
obligations shall be exercised and performed by a co-trustee;

          (c) the Trustee at any time, by an instrument in writing executed by
it, with the concurrence of the Issuer and the Co-Issuer evidenced by an Issuer
Order, may accept the resignation of, or remove, any co-trustee appointed under
this Section 6.12, and in case an Event of Default has occurred and is
continuing, the Trustee shall have the power to accept the resignation of, or
remove, any such co-trustee without the concurrence of the Issuer or the
Co-Issuer. A successor to any co-trustee so resigned or removed may be appointed
in the manner provided in this Section 6.12;

          (d) no co-trustee hereunder shall be personally liable by reason of
any act or omission of the Trustee hereunder;

          (e) the Trustee shall not be liable by reason of any act or omission
of a co-trustee; and

          (f) any Act of Securityholders delivered to the Trustee shall be
deemed to have been delivered to each co-trustee.

          Section 6.13 Certain Duties of Trustee Related to Delayed Payment of
Proceeds.

          In the event that in any month the Trustee shall not have received a
Scheduled Distribution, (a) the Trustee shall promptly notify the Issuer and the
Collateral Manager in writing and (b) unless within three Business Days (or the
end of the applicable grace period for such payment, if longer) after such
notice such payment shall have been received by the Trustee, or the Issuer, in
its absolute discretion (but only to the extent permitted by Section 10.2(a)),
shall have made provision for such payment satisfactory to the Trustee in
accordance with Section 10.2(a), the Trustee shall request the obligor of such
Pledged Obligation, the trustee under the related Underlying Instrument or
paying agent designated by either of them, as the case may be,

to make such payment as soon as practicable after such request but in no event
later than three Business Days after the date of such request. In the event that
such payment is not made within such time period, the Trustee, subject to the
provisions of Section 6.1(d)(iv), shall take such action as the Collateral
Manager reasonably shall direct in writing. Any such action shall be without
prejudice to any right to claim a Default or Event of Default under this
Indenture. In the event that the Issuer or the Collateral Manager requests a
release of a Pledged Obligation in connection with any such action under the
Collateral Management Agreement, such release shall be subject to Section 10.12
and Article 12 of this Indenture, as the case may be. Notwithstanding any other
provision hereof, the Trustee shall deliver to the Issuer or its designee any
payment with respect to any Pledged Obligation received after the Due Date
thereof to the extent the Issuer previously made provisions for such payment
satisfactory to the Trustee in accordance with this Section 6.13 and such
payment shall not be deemed part of the Assets.

          Section 6.14 Representations and Warranties of the Trustee.

          The Trustee represents and warrants that:

          (a) the Trustee is a national banking association with trust powers,
duly and validly existing under the laws of the United States of America, with
corporate power and authority to execute, deliver and perform its obligations
under this Indenture, and is duly eligible and qualified to act as trustee under
this Indenture;

          (b) this Indenture has been duly authorized, executed and delivered by
the Trustee and constitutes the valid and binding obligation of the Trustee,
enforceable against it in accordance with its terms except (i) as limited by
bankruptcy, fraudulent conveyance, fraudulent transfer, insolvency,
reorganization, liquidation, receivership, moratorium or other similar laws now
or hereafter in effect relating to creditors' rights generally and by general
equitable principles, regardless of whether considered in a proceeding in equity
or at law, and (ii) that the remedy of specific performance and injunctive and
other forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought;

          (c) neither the execution or delivery by the Trustee of this Indenture
nor the performance by the Trustee of its obligations under this Indenture
requires the consent or approval of, the giving of notice to or the registration
or filing with, any governmental authority or agency under any existing law of
the United States of America governing the banking or trust powers of the
Trustee;

          (d) neither the execution, delivery and performance of this Indenture,
nor the consummation of the transactions contemplated by this Indenture, (i) is
prohibited by, or requires the Trustee to obtain any consent, authorization,
approval or registration under, any law, statute, rule, regulation, or any
judgment, order, writ, injunction or decree that is binding upon the Trustee or
any of its properties or assets, (ii) will violate the provisions of the
Governing Documents of the Trustee or (iii) will violate any provision of,
result in any default or acceleration of any obligations under, result in the
creation or imposition of any lien pursuant to, or require any consent under,
any material agreement to which the Trustee is a party or by which


                                      -162-

<PAGE>

it or any of its property is bound, the violation of which would have a material
adverse effect on the Trustee or its property; and

          (e) there are no proceedings pending or, to the best knowledge of the
Trustee, threatened against the Trustee before any Federal, state or other
governmental agency, authority, administrator or regulatory body, arbitrator,
court or other tribunal, foreign or domestic, which could have a material
adverse effect on the Pledged Obligations or the performance by the Trustee of
its obligations under this Indenture.

          Section 6.15 Requests for Consents.

          In the event that the Trustee receives written notice of any proposed
amendment, consent or waiver under the Underlying Instruments of any Collateral
Debt Security (before or after any default) or in the event any action is
required to be taken in respect to an Underlying Instrument, the Trustee shall
promptly contact the Issuer and the Collateral Manager. The Collateral Manager
may, on behalf of the Issuer, instruct the Trustee pursuant to an Issuer Order
to, and the Trustee shall, with respect to which a Collateral Debt Security as
to which a consent or waiver under the Underlying Instruments of such Collateral
Debt Security (before or after any default) has been proposed or with respect to
action required to be taken in respect of an Underlying Instrument, give
consent, grant a waiver, vote or exercise any or all other rights or remedies
with respect to any such Collateral Debt Security in accordance with such Issuer
Order. In the absence of any instruction from the Collateral Manager, the
Trustee shall not engage in any vote or take any action with respect to such a
Collateral Debt Security.

          Section 6.16 Withholding.

          If any amount is required to be deducted or withheld from any payment
to any Noteholder, such amount shall reduce the amount otherwise distributable
to such Noteholder. The Trustee is hereby authorized to withhold or deduct from
amounts otherwise distributable to any Noteholder sufficient funds for the
payment of any tax that is legally required to be withheld or deducted (but such
authorization shall not prevent the Trustee from contesting any such tax in
appropriate proceedings and legally withholding payment of such tax, pending the
outcome of such proceedings). The amount of any withholding tax imposed with
respect to any Noteholder shall be treated as Cash distributed to such
Noteholder at the time it is deducted or withheld by the Issuer or the Trustee,
as applicable, and remitted to the appropriate taxing authority. If there is a
possibility that withholding tax is payable with respect to a distribution, the
Trustee may in its sole discretion withhold such amounts in accordance with this
Section 6.16. If any Noteholder wishes to apply for a refund of any such
withholding tax, the Trustee shall reasonably cooperate with such Noteholder in
making such claim so long as such Noteholder agrees to reimburse the Trustee for
any out-of-pocket expenses incurred. Nothing herein shall impose an obligation
on the part of the Trustee to determine the amount of any tax or withholding
obligation on the part of the Issuer or in respect of the Notes.

          Section 7.1 Payment of Principal and Interest and Class A-1AR
Commitment Fee.

          The Issuer and the Co-Issuer shall duly and punctually pay the
principal of and interest on each Class of Notes, and in the case of the Class
A-1AR Notes, the Class A-1AR Commitment Fee and any Class A-1AR Breakage Costs,
in accordance with the terms of such Notes and this Indenture. Amounts properly
withheld under the Code or other applicable law by any Person from a payment to
any Noteholder of interest and/or principal shall be considered as having been
paid by the Issuer and the Co-Issuer, and, with respect to the Preferred Shares,
by the Issuer, to such Preferred Shareholder for all purposes of this Indenture.

          The Trustee shall, unless prevented from doing so for reasons beyond
its reasonable control, give notice to each Securityholder of any such
withholding requirement no later than ten days prior to the related Payment Date
from which amounts are required (as directed by the Issuer (or the Collateral
Manager on behalf of the Issuer)) to be withheld, provided that, despite the
failure of the Trustee to give such notice, amounts withheld pursuant to
applicable tax laws shall be considered as having been paid by the Issuer and
the Co-Issuer, as provided above.

          Section 7.2 Maintenance of Office or Agency.

          The Issuer and the Co-Issuer hereby appoint the Trustee as a Paying
Agent for the payment of principal of and interest on the Notes and where Notes
may be surrendered for registration of transfer or exchange and the Issuer and
the Co-Issuer hereby appoint CT Corporation System, 111 Eighth Avenue, 13th
Floor, New York, New York 10011, as their agent where notices and demands to or
upon the Co-Issuer in respect of the Notes or this Indenture, or the Issuer in
respect of the Notes or this Indenture, may be served.

          The Issuer and the Co-Issuer hereby appoint the Irish Paying Agent as
a Paying Agent for the payment of principal of and interest on the Notes and to
act as their agent where notices and demands to or upon the Issuer or the
Co-Issuer in respect of the Notes or this Indenture may be served and where
Notes may be surrendered for registration of transfer or exchange.

          The Issuer or the Co-Issuer may at any time and from time to time vary
or terminate the appointment of any such agent or appoint any additional agents
for any or all of such purposes; provided, however, that the Issuer and the
Co-Issuer, if applicable, will maintain in the Borough of Manhattan, The City of
New York, an office or agency where notices and demands to or upon the Issuer
and the Co-Issuer in respect of the Notes and this Indenture may be served, and,
subject to any laws or regulations applicable thereto, an office or agency
outside of the United States where Notes may be presented and surrendered for
payment; provided, further, that no paying agent shall be appointed in a
jurisdiction which subjects payments on the Notes to withholding tax. The Issuer
or the Co-Issuer, as the case may be, shall give prompt written notice to the
Trustee, the Class A-1AR Note Agent, each Rating Agency and the Noteholders of
the appointment or termination of any such agent and of the location and any
change in the location of any such office or agency.


                                     -164-
<PAGE>

          If at any time the Issuer and the Co-Issuer, if applicable, shall fail
to maintain any such required office or agency in the Borough of Manhattan, The
City of New York, or outside the United States, or shall fail to furnish the
Trustee with the address thereof, presentations and surrenders may be made
(subject to the limitations described in the preceding paragraph) at and notices
and demands may be served on the Issuer and the Co-Issuer, and Notes may be
presented and surrendered for payment to the appropriate Paying Agent at its
main office and the Issuer and the Co-Issuer hereby appoint the same as their
agent to receive such respective presentations, surrenders, notices and demands.

          Section 7.3 Money for Note Payments to be Held in Trust.

          All payments of amounts due and payable with respect to any Notes that
are to be made from amounts withdrawn from the Payment Account shall be made on
behalf of the Issuer and the Co-Issuer by the Trustee or a Paying Agent (in each
case, from and to the extent of available funds in the Payment Account and
subject to the Priority of Payments) with respect to payments on the Notes.

          When the Paying Agent is not also the Notes Registrar, the Issuer and
the Co-Issuer shall furnish, or cause the Notes Registrar to furnish, no later
than the fifth calendar day after each Record Date a list, if necessary, in such
form as such Paying Agent may reasonably request, of the names and addresses of
the Holders of Notes and of the certificate numbers of individual Notes held by
each such Holder.

          Whenever the Paying Agent is not also the Trustee, the Issuer, the
Co-Issuer, and such Paying Agent shall, on or before the Business Day next
preceding each Payment Date or Redemption Date, as the case may be, direct the
Trustee to deposit on such Payment Date with such Paying Agent, if necessary, an
aggregate sum sufficient to pay the amounts then becoming due pursuant to the
terms of this Indenture (to the extent funds are then available for such purpose
in the Payment Account, and subject to the Priority of Payments), such sum to be
held for the benefit of the Persons entitled thereto and (unless such Paying
Agent is the Trustee) the Issuer and the Co-Issuer shall promptly notify the
Trustee of its action or failure so to act. Any Monies deposited with a Paying
Agent (other than the Trustee) in excess of an amount sufficient to pay the
amounts then becoming due on the Notes with respect to which such deposit was
made shall be paid over by such Paying Agent to the Trustee for application in
accordance with Article 11. Any such Paying Agent shall be deemed to agree by
assuming such role not to cause the filing of a petition in bankruptcy against
the Issuer or the Co-Issuer for the non-payment to the Paying Agent of any
amounts payable thereto until at least one year and one day (or, if longer, the
applicable preference period then in effect) after the payment in full of all
Notes issued under this Indenture.

          The initial Paying Agent shall be as set forth in Section 7.2. Any
additional or successor Paying Agents shall be appointed by Issuer Order of the
Issuer and Issuer Order of the Co-Issuer with written notice thereof to the
Trustee; provided, however, that so long as any Class of the Notes are rated by
a Rating Agency and with respect to any additional or successor Paying Agent for
the Notes, either (i) such Paying Agent has a long-term debt rating of "Aa3" or
higher by Moody's, "AA-"or higher by Fitch and "AA-" or higher by S&P or a
short-term debt rating of "P-1" by Moody's, "F1+" by Fitch and "A-1+" by S&P or
(ii) each Rating Agency confirms that


                                     -165-

<PAGE>

employing such Paying Agent shall not adversely affect the then-current ratings
of the Notes. In the event that such successor Paying Agent ceases to have a
long-term debt rating of "Aa3" or higher by Moody's, "AA-"or higher by Fitch or
"AA-" or higher by S&P or a short-term debt rating of at least "P-1" by Moody's,
"F1+" by Fitch and "A-1+" by S&P, the Issuer and the Co-Issuer shall promptly
remove such Paying Agent and appoint a successor Paying Agent. The Issuer and
the Co-Issuer shall not appoint any Paying Agent that is not, at the time of
such appointment, a depository institution or trust company subject to
supervision and examination by federal and/or state and/or national banking
authorities. The Issuer and the Co-Issuer shall cause the 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 (and if the Trustee acts as
Paying Agent, it hereby so agrees), subject to the provisions of this Section
7.3, that such Paying Agent will:

          (a) allocate all sums received for payment to the Holders of Notes for
which it acts as Paying Agent on each Payment Date and Redemption Date among
such Holders in the proportion specified in the applicable report or Redemption
Date Statement, as the case may be, in each case to the extent permitted by
applicable law;

          (b) hold all sums held by it for the payment of amounts due with
respect to the Notes 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;

          (c) if such Paying Agent is not the Trustee, immediately resign as a
Paying Agent and forthwith pay to the Trustee all sums held by it for the
payment of Notes if at any time it ceases to meet the standards set forth above
required to be met by a Paying Agent at the time of its appointment;

          (d) if such Paying Agent is not the Trustee, immediately give the
Trustee notice of any Default by the Issuer or the Co-Issuer (or any other
obligor upon the Notes) in the making of any payment required to be made; and

          (e) if such Paying Agent is not the Trustee 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 by such Paying Agent.

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

          Except as otherwise required by applicable law, any Money deposited
with the Trustee in trust or deposited with the Paying Agent for the payment of
the principal of or interest on any Note and remaining unclaimed for two years
after such principal or interest has become due and payable shall be paid to the
Issuer; and the Holder of such Note shall thereafter, as an


                                     -166-

<PAGE>

unsecured general creditor, look only to the Issuer for payment of such amounts
and all liability of the Trustee or the Paying Agent with respect to such Money
(but only to the extent of the amounts so paid to the Issuer or the Co-Issuer,
as applicable) shall thereupon cease; provided, however, that the Irish Paying
Agent, before being required to make any such payment, shall at the expense of
the Issuer cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in Dublin, Ireland, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining shall be
repaid to the Issuer. The Trustee or the Paying Agent, before being required to
make any such release of payment, may, but shall not be required to, adopt and
employ, at the expense of the Issuer or the Co-Issuer, as the case may be, any
reasonable means of notification of such release of payment, including, but not
limited to, mailing notice of such release to Holders whose Notes 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 Paying Agent, at the last address of record of each such Holder.

          Section 7.4 Existence of the Issuer and Co-Issuer.

          (a) So long as any Note is Outstanding, the Issuer shall, to the
maximum extent permitted by applicable law, maintain in full force and effect
its existence and rights as an exempted company incorporated with limited
liability under the laws of the Cayman Islands and shall obtain and preserve its
qualification to do business as a foreign limited liability company in each
jurisdiction in which such qualifications are or shall be necessary to protect
the validity and enforceability of this Indenture, the Notes or any of the
Assets; provided that the Issuer shall be entitled to change its jurisdiction of
registration from the Cayman Islands to any other jurisdiction reasonably
selected by the Issuer so long as (i) such change is not disadvantageous in any
material respect to the Holders of the Notes or the Preferred Shares or any
Hedge Counterparty, (ii) written notice of such change shall have been given by
the Trustee to the Holders of the Notes or Preferred Shares, the Preferred
Shares Paying Agent, each Hedge Counterparty and each Rating Agency 15 Business
Days prior to such change and (iii) on or prior to the 15th Business Day
following such notice the Trustee shall not have received written notice from a
Majority of the Controlling Class or a Majority of the Preferred Shares or any
Hedge Counterparty objecting to such change. So long as any Note is Outstanding,
the Issuer will maintain at all times at least one director who is Independent
of the Collateral Manager and its Affiliates.

          (b) So long as any Note is Outstanding, the Co-Issuer shall maintain
in full force and effect its existence and rights as a limited liability company
organized under the laws of Delaware and shall obtain and preserve its
qualification to do business as a foreign limited liability company in each
jurisdiction in which such qualifications are or shall be necessary to protect
the validity and enforceability of this Indenture or the Notes; provided,
however, that the Co-Issuer shall be entitled to change its jurisdiction of
formation from Delaware to any other jurisdiction reasonably selected by the
Co-Issuer so long as (i) such change is not disadvantageous in any material
respect to the Holders of the Notes or any Hedge Counterparty, (ii) written
notice of such change shall have been given by the Trustee to the Holders of the
Notes, each Hedge Counterparty and each Rating Agency 15 Business Days prior to
such change and (iii) on or prior to the 15th Business Day following such notice
the Trustee shall not have


                                     -167-

<PAGE>

received written notice from a Majority of the Controlling Class or any Hedge
Counterparty objecting to such change. So long as any Note is Outstanding, the
Co-Issuer shall maintain at all times at least one manager who is Independent of
the Collateral Manager and its Affiliates.

          (c) So long as any Note is Outstanding, the Issuer shall ensure that
all corporate or other formalities regarding its existence are followed
(including correcting any known misunderstanding regarding its separate
existence). So long as any Note is Outstanding, the Issuer shall not take any
action or conduct its affairs in a manner that is likely to result in its
separate existence being ignored or its assets and liabilities being
substantively consolidated with any other Person in a bankruptcy, reorganization
or other insolvency proceeding. So long as any Note is Outstanding, the Issuer
shall maintain and implement administrative and operating procedures reasonably
necessary in the performance of the Issuer's obligations hereunder, and the
Issuer shall at all times keep and maintain, or cause to be kept and maintained,
separate books, records, accounts and other information customarily maintained
for the performance of the Issuer's obligations hereunder. Without limiting the
foregoing, so long as any Note is Outstanding, (i) the Issuer shall (A) pay its
own liabilities only out of its own funds and (B) use separate stationery,
invoices and checks, (C) hold itself out and identify itself as a separate and
distinct entity under its own name and (ii) the Issuer shall not (A) have any
subsidiaries, (B) have any employees (other than its directors), (C) engage in
any transaction with any shareholder that is not permitted under the terms of
the Collateral Management Agreement, (D) pay dividends other than in accordance
with the terms of this Indenture, its governing documents and the Preferred
Shares Paying Agency Agreement, (E) conduct business under an assumed name
(i.e., no "DBAs"), (F) commingle its funds or assets with those of any other
Person, or (G) enter into any contract or agreement with any of its Affiliates,
except upon terms and conditions that are commercially reasonable and
substantially similar to those available in arm's-length transactions with an
unrelated party.; provided that the foregoing shall not prohibit the Issuer from
entering into the transactions contemplated by the Administration Agreement with
the Company Administrator, the Preferred Shares Paying Agency Agreement with the
Share Registrar and any other agreement contemplated or permitted by the
Collateral Management Agreement or this Indenture.

          (d) So long as any Note is Outstanding, the Co-Issuer shall ensure
that all limited liability company or other formalities regarding its existence
are followed, as well as correcting any known misunderstanding regarding its
separate existence. The Co-Issuer shall not take any action or conduct its
affairs in a manner, that is likely to result in its separate existence being
ignored or its assets and liabilities being substantively consolidated with any
other Person in a bankruptcy, reorganization or other insolvency proceeding. The
Co-Issuer shall maintain and implement administrative and operating procedures
reasonably necessary in the performance of the Co-Issuer's obligations
hereunder, and the Co-Issuer shall at all times keep and maintain, or cause to
be kept and maintained, books, records, accounts and other information
customarily maintained for the performance of the Co- Issuer's obligations
hereunder. Without limiting the foregoing, the Co-Issuer shall not (A) have any
subsidiaries, (B) have any employees (other than its managers), (C) join in any
transaction with any member that is not permitted under the terms of the
Collateral Management Agreement, (D) pay dividends other than in accordance with
the terms of this Indenture, (E) commingle its funds or assets with those of any
other Person, or (F) enter into any contract or agreement with any of its
Affiliates, except upon terms and conditions


                                     -168-

<PAGE>

that are commercially reasonable and substantially similar to those available in
arm's-length transactions with an unrelated party.

          Section 7.5 Protection of Assets.

          (a) The Trustee, on behalf of the Issuer, pursuant to any Opinion of
Counsel received pursuant to Section 7.5(d) shall execute and deliver all such
Financing Statements, continuation statements, instruments of further assurance
and other instruments, and shall take such other action as may be necessary or
advisable or desirable to secure the rights and remedies of the Holders and each
Hedge Counterparty hereunder and to:

          (i) Grant more effectively all or any portion of the Assets;

          (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

     regulations);

          (iv) enforce any of the Pledged Obligations or other instruments or
     property included in the Assets;

          (v) preserve and defend title to the Assets and the rights of the
     Trustee, the Holders of the Notes and each Hedge Counterparty in the Assets
     against the claims of all persons and parties; and

          (vi) pursuant to Sections 11.1(a)(i)(1) and 11.1(a)(ii)(1), pay or
     cause to be paid any and all taxes levied or assessed upon all or any part
     of the Assets.

          The Issuer hereby designates the Trustee as its agent and
attorney-in-fact to execute any Financing Statement, continuation statement or
other instrument required pursuant to this Section 7.5. The Trustee agrees that
it will from time to time execute and cause to be filed Financing Statements and
continuation statements (it being understood that the Trustee shall be entitled
to rely upon an Opinion of Counsel described in Section 7.5(d), at the expense
of the Issuer, as to the need to file such Financing Statements and continuation
statements, the dates by which such filings are required to be made and the
jurisdictions in which such filings are required to be made).

          (b) The Trustee shall not (except in accordance with Section 10.12(a),
(b) or (c) and except for payments, deliveries and distributions otherwise
expressly permitted under this Indenture) (i) remove any portion of the Assets
that consists of Cash or is evidenced by an instrument, certificate or other
writing (A) from the jurisdiction in which it was held at the date as described
in the Opinion of Counsel delivered at the Closing Date pursuant to Section
3.1(d) or (B) from the possession of the Person who held it on such date or (ii)
cause or permit the Custodial Account or the Custodial Securities Intermediary
to be located in a different jurisdiction from the jurisdiction in which such
securities accounts and Custodial Securities Intermediary were located on the
Closing Date, unless the Trustee shall have first received an


                                     -169-

<PAGE>

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 Issuer shall (i) pay or cause to be paid taxes, if any, levied
on account of the beneficial ownership by the Issuer of any Pledged Obligations
that secure the Notes and timely file all tax returns and information statements
as required, and (ii) if required to prevent the withholding or imposition of
United States income tax, deliver or cause to be delivered a United States
Internal Revenue Service Form W-9 or successor applicable form, to each issuer,
counterparty or paying agent with respect to (as applicable) an item included in
the Assets at the time such item is purchased or entered into and thereafter
prior to the expiration or obsolescence of such form.

          (d) For so long as the Notes are Outstanding, (i) on December 31, 2011
and (ii) every 60 months after such date, the Issuer (or the Collateral Manager
on behalf of the Issuer) shall deliver to the Trustee for the benefit of the
Trustee, the Collateral Manager, each Hedge Counterparty and each Rating Agency,
at the expense of the Issuer, an Opinion of Counsel stating what is required, in
the opinion of such counsel, as of the date of such opinion, to maintain the
lien and security interest created by this Indenture with respect to the Assets,
and confirming the matters set forth in the Opinion of Counsel, furnished
pursuant to Section 3.1(d), with regard to the perfection and priority of such
security interest (and such Opinion may likewise be subject to qualifications
and assumptions similar to those set forth in the Opinion delivered pursuant to
Section 3.1(d)).

          Section 7.6 Notice of Any Amendments.

          Each of the Issuer and the Co-Issuer shall give notice to the Rating
Agencies of, and satisfy the Rating Agency Condition and, so long as MBIA is
deemed to be the Controlling Class hereunder, obtain the consent of MBIA with
respect to, any amendments to its Governing Documents.

          Section 7.7 Performance of Obligations.

          (a) Each of the Issuer and the Co-Issuer shall not take any action,
and will use commercially reasonable 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 instrument included in the Assets, except in
the case of enforcement action taken with respect to any Defaulted Security in
accordance with the provisions hereof and as otherwise required hereby.

          (b) The Issuer or the Co-Issuer may, with the prior written consent of

<PAGE>

beneficial owner or to the Trustee for delivery to such Holder or beneficial
owner or a prospective purchaser designated by such Holder or beneficial owner,
as the case may be, in order to permit compliance by such Holder or beneficial
owner with Rule 144A under the Securities Act in connection with the resale of
such Note by such Holder or beneficial owner. "Rule 144A Information" shall be
such information as is specified pursuant to Rule 144A(d)(4) under the

prospective purchasers, at and pursuant to the Issuer's and/or the Co-Issuer's
written direction the foregoing materials prepared by or on behalf of the Issuer
and/or the Co-Issuer; provided, however, that the Trustee shall be entitled to
prepare and affix thereto or enclose therewith reasonable disclaimers to the
effect that such Rule 144A Information was not assembled by the Trustee, that
the Trustee has not reviewed or verified the accuracy thereof, and that it makes
no representation as to such accuracy or as to the sufficiency of such
information under the requirements of Rule 144A or for any other purpose.

          Section 7.14 Calculation Agent.

          (a) The Issuer and the Co-Issuer hereby agree that for so long as any
Notes remain Outstanding there shall at all times be an agent appointed to
calculate LIBOR in respect of each Interest Accrual Period in accordance with
the terms of Schedule J attached hereto (the "Calculation Agent"). The Issuer
and the Co-Issuer initially have appointed the Trustee as Calculation Agent for
purposes of determining LIBOR for each Interest Accrual Period. The Calculation
Agent may be removed by the Issuer at any time. The Calculation Agent may resign
at any time by giving written notice thereof to the Issuer, the Co-Issuer, the
Collateral Manager, each Hedge Counterparty, the Class A-1AR Note Agent, the
Noteholders and each Rating Agency. If the Calculation Agent is unable or
unwilling to act as such or is removed by the Issuer in respect of any Interest
Accrual Period, the Issuer and the Co-Issuer shall, with the prior written
consent of each Hedge Counterparty and the Class A-1AR Note Agent, promptly
appoint as a replacement Calculation Agent a leading bank which is engaged in
transactions in Eurodollar deposits in the international Eurodollar market and
which does not control or is not controlled by or under common control with the
Issuer or its Affiliates. The Calculation Agent may not resign its duties
without a successor having been duly appointed, and shall promptly inform the
Hedge Counterparty and the Class A-1AR Note Agent of any such appointment. If no
successor Calculation Agent shall have been appointed within 30 days after
giving of a notice of resignation, the resigning Calculation Agent, each Hedge
Counterparty, the Class A-1AR Note Agent, a Majority of the Notes or any Holder
of a Note, on behalf of himself and all others similarly situated, may petition
a court of competent jurisdiction for the appointment of a successor Calculation
Agent.

          (b) The Calculation Agent shall be required to agree that, as soon as
practicable after 11:00 a.m. (London time) on each LIBOR Determination Date (as
defined in Schedule J attached hereto), but in no event later than 11:00 a.m.
(New York time) on the London Banking Day immediately following each LIBOR
Determination Date, the Calculation Agent shall calculate (x) LIBOR for the next
Interest Accrual Period and (y) the amount of interest for such Interest Accrual
Period payable in respect of each $1,000 principal amount of each Class of Notes
(rounded to the nearest cent, with half a cent being rounded upward) on the
related Payment Date, and will communicate such rates and amounts to the Issuer,
the Co-Issuer, the Trustee, the Collateral Manager, the Paying Agent, each Hedge
Counterparty and, if any


                                     -178-

<PAGE>

Note is in the form of a Regulation S Global Security, to Euroclear and
Clearstream, Luxembourg. The Calculation Agent shall also specify to the Issuer
and the Co-Issuer the quotations upon which LIBOR is based, and in any event the
Calculation Agent shall notify the Issuer and the Co-Issuer before 5:00 p.m.
(New York time) on each LIBOR Determination Date if it has not determined and is
not in the process of determining LIBOR and the Interest Distribution Amounts
for each Class of Notes, together with the reasons therefor. The determination
of the Class A-1A Rate, Class A-1AR Rate, Class A-2 Rate, Class B Rate, Class C
Rate, Class D Rate, Class E Rate, Class F Rate, Class G Rate and Class H Rate
and the related Class A-1A Interest Distribution Amount, Class A-1AR Interest
Distribution Amount, Class A-2 Interest Distribution Amount, Class B Interest
Distribution Amount, Class C Interest Distribution Amount, Class D Interest
Distribution Amount, Class E Interest Distribution Amount, Class F Interest
Distribution Amount, Class G Interest Distribution Amount and Class H Interest
Distribution Amount, respectively, by the Calculation Agent shall, absent
manifest error, be final and binding on all parties.

          Section 7.15 Maintenance of Listing.

          (a) For so long as any of the Notes remain Outstanding, the Issuer and
Co-Issuer shall use all reasonable efforts to arrange and maintain the listing
of the Notes (other than the Class A-1AR Notes) on the Irish Stock Exchange.

          (b) If the Notes (other than the Class A-1AR Notes) are listed on the
Irish Stock Exchange, the Issuer shall:

          (i) in each calendar year commencing in 2007, request from the Irish
     Stock Exchange a waiver of the Irish Stock Exchange's requirement to
     publish annual reports and accounts;

          (ii) submit to the Irish Stock Exchange draft copies of any proposed
     amendments to the Governing Documents which would affect the rights of the
     Holders of the Notes listed on the Irish Stock Exchange;

          (iii) pay the annual fee for listing the Notes (other than the Class
     A-1AR Notes) on the Irish Stock Exchange, if any; and

          (iv) inform the Irish Stock Exchange if the rating assigned to any of
     the Notes is reduced or withdrawn.

          (c) All notices, documents, reports and other announcements delivered
to such Company Announcements Office shall be in the English language.

          (d) Notwithstanding the foregoing, if the Collateral Manager on behalf
of the Co-Issuers determines that the maintenance of the listing of any Class of
Notes on the Irish Stock Exchange (or any alternative listing on another
securities exchange) is unduly onerous or burdensome, the Co-Issuers will have
the right to cause such Class of Notes to be delisted from the Irish Stock
Exchange (or such other securities exchange). If any such delisting occurs with
respect to such Class, the Issuer shall use reasonable efforts to apply for the
alternative listing of such Class on such other securities exchange as the
Collateral Manager on behalf of the Issuer


                                     -179-

<PAGE>

may choose, except to the extent that the Collateral Manager determines on
behalf of the Issuer that obtaining or maintaining such alternative listing
would itself be unduly onerous or burdensome. Without limiting the Collateral
Manager's discretion with respect to any determination that maintaining or
obtaining a listing is unduly onerous or burdensome, the Collateral Manager may
take into account various factors, including any requirement, resulting from a
listing, that either Co-Issuer prepare financial statements of any particular
kind or provide additional disclosure of any particular kind, in each case
including any such requirement arising out of disclosure or transparency
directives of the European Union or any other law or governmental rule.

          Section 7.16 Purchase of Assets.

          The Issuer (or the Collateral Manager on behalf of the Issuer) shall
use commercially reasonable efforts to invest Principal Proceeds, any remaining
Deposit and any Reinvestment Income during the Ramp-Up Period in Collateral Debt
Securities in accordance with the provisions hereof. Subject to the provisions
of this Section 7.17, Principal Proceeds, all or any portion of any remaining
Deposit and any Reinvestment Income thereon may be applied prior to the
Effective Date to purchase Collateral Debt Securities (which shall be, and
hereby are, Granted to the Trustee pursuant to the Granting Clause of this
Indenture) for inclusion in the Assets upon receipt by the Trustee of an Issuer
Order executed by the Issuer (or the Collateral Manager on behalf of the Issuer)
with respect thereto directing the Trustee to pay out the amount specified
therein against delivery of the Collateral Debt Security specified therein and a
certificate of an Authorized Officer of the Issuer (or the Collateral Manager),
dated as of the trade date, and delivered to the Trustee on or prior to the date
of such purchase and Grant, to the effect that the criteria set forth below in
this Section 7.17 will be satisfied (such criteria to be applied as of the trade
date) after giving effect to such purchase and Grant of the Collateral Debt
Securities:

          (a) the Eligibility Criteria are met with respect to the Collateral
Debt Securities purchased;

          (b) the Reinvestment Criteria are satisfied after giving effect to
such investment; and

          (c) the procedures relating to the perfection of the Trustee's
security interest in the Collateral Debt Securities described in this Indenture
have been satisfied.

          Section 7.17 Effective Date Actions.

          (a) The Issuer (or the Collateral Manager on behalf of the Issuer)
shall cause to be delivered to the Trustee and each Rating Agency on the
Effective Date an amended Schedule of Closing Date Collateral Debt Securities
listing all Collateral Debt Securities Granted to the Trustee pursuant to
Section 7.17 on or before the Effective Date and included in the Assets on the
Effective Date, which schedule shall supersede any prior Schedule of Closing
Date Collateral Debt Securities delivered to the Trustee.

          (b) Within ten Business Days after the Effective Date, the Issuer (or
the Collateral Manager on behalf of the Issuer) shall request each Rating Agency
rating a Class of


                                     -180-

<PAGE>

Notes to confirm within 20 Business Days after the Effective Date, and to so
notify in writing the Trustee and any Hedge Counterparty, that it has not
reduced or withdrawn the ratings assigned by it on the Closing Date to such
Class of Notes. If, within 20 Business Days after the Effective Date, any rating
assigned as of the Closing Date to any Class of Notes has not been confirmed, or
is reduced or withdrawn, the Collateral Manager may, on behalf of the Issuer,
within ten Business Days, provide to such Rating Agency a proposal (a
"Proposal") with respect to the Collateral Debt Securities. If such Rating
Agency does not accept the Proposal, or the Collateral Manager, on behalf of the
Issuer, elects not to submit a Proposal, a "Rating Confirmation Failure" shall
have occurred. If such Rating Agency accepts the Proposal, a Rating Confirmation
Failure shall not be deemed to have occurred unless and until the Collateral
Manager fails to meet the conditions set forth in the Proposal in accordance
with the time requirements set forth in such Proposal. Within ten Business Days
after the conditions set forth in the Proposal have been satisfied, the Issuer
shall be required to request a Rating Confirmation. If the relevant Rating
Agency does not confirm its ratings, a Rating Confirmation Failure shall have
occurred. If a Rating Confirmation Failure occurs, on the first Payment Date
thereafter, (i) as provided in Section 10.4, all amounts remaining on deposit in
the Unused Proceeds Account, (ii) as provided in Section 11.1(a)(i), all
Interest Proceeds remaining after payment of the amounts referred to in clauses
(1) through (23) of Section 11.1(a)(i) and (iii) as provided in Section
11.1(a)(ii), all Principal Proceeds remaining after payment of the amounts
referred to in clauses (1) through (6) of Section 11.1(a)(ii), in each case will
be used to pay principal of each such Class of Notes, in each case sequentially
in accordance with the Priority of Payments, until each such rating is confirmed
or reinstated or such Class of Notes has been paid in full (and, in the case of
the Class A-1AR Notes, the Class A-1AR Commitments have been reduced to zero).

          (c) The Collateral Manager on behalf of the Issuer shall cause to be
delivered to the Trustee, each Hedge Counterparty and each Rating Agency, within
six Business Days after the Effective Date, an Accountants' Report, dated as of
the Effective Date, confirming that the Collateral Quality Tests and the
Coverage Tests have been satisfied and that the Collateral Debt Securities
(together with the Aggregate Class A-1AR Undrawn Amount) have an aggregate par
amount (or, in the case of the Aggregate Class A-1AR Undrawn Amount, an
aggregate dollar amount) equal to at least the Minimum Ramp-Up Amount and
certifying the procedures applied and such accountants' associated findings with
respect to the Eligibility Criteria and specifying the procedures undertaken by
them to review data and computations relating to such information. The
Collateral Manager may on any date, prior to the 270th day following the Closing
Date or the purchase of Collateral Debt Securities (together with the Aggregate
Class A-1AR Undrawn Amount) having an aggregate par amount equal to the Minimum
Ramp-Up Amount, upon written notice to the Trustee, the Class A-1AR Note Agent,
the Issuer and the Co-Issuer and each Rating Agency (with a copy to each Hedge
Counterparty), declare that the Effective Date shall occur on the date specified
in such notice; provided that each of the Collateral Quality Tests and the
Coverage Tests will be satisfied as of such Effective Date, the Rating Agency
Condition has been satisfied and, so long as MBIA is deemed to be the
Controlling Class hereunder, MBIA has consented. The Issuer (or the Collateral
Manager on behalf of the Issuer) shall cause to be delivered to S&P on the
Effective Date a Microsoft Excel file that provides all of the inputs required
to determine whether the S&P CDO Monitor Test has been satisfied.

          The Arbor Parent shall not take any action that results in the Issuer
failing to qualify as a Qualified REIT Subsidiary of the Arbor Parent for
federal income tax purposes, unless (A) based on an Opinion of Counsel, the
Issuer will be treated as a Qualified REIT Subsidiary of a REIT other than Arbor
Parent, or (B) based on an Opinion of Counsel, the Issuer will be treated as a
foreign corporation that is not engaged in a trade or business in the United
States for U.S. federal income tax purposes.

                             SUPPLEMENTAL INDENTURES

          Section 8.1 Supplemental Indentures Without Consent of
Securityholders.

          Without the consent of the Holders of any Notes or any Preferred
Shareholders, the Issuer, the Co-Issuer, when authorized by Board Resolutions,
and the Trustee, with the written consent of each Hedge Counterparty delivered
to the Issuer, the Co-Issuer and the Trustee, and, at any time and from time to
time subject to the requirement provided below in this Section 8.1, may enter
into one or more indentures supplemental hereto, in form satisfactory to the
Trustee, for any of the following purposes:

          (a) to evidence the succession of another Person to the Issuer or the
Co-Issuer and the assumption by any such successor Person of the covenants of
the Issuer or the Co-Issuer herein and in the Notes;

          (b) to add to the covenants of the Issuer, the Co-Issuer or the
Trustee for the benefit of the Holders of the Notes, Preferred Shareholders,
each Hedge Counterparty or to surrender any right or power herein conferred upon
the Issuer or the Co-Issuer, as applicable;

          (c) to convey, transfer, assign, mortgage or pledge any property to or
with the Trustee, or add to the conditions, limitations or restrictions on the
authorized amount, terms and purposes of the issue, authentication and delivery
of the Notes;

          (d) to evidence and provide for the acceptance of appointment
hereunder of a successor Trustee 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
Sections 6.9, 6.10 and 6.12 hereof;

          (e) to correct or amplify the description of any property at any time
subject to the lien of this Indenture, or to better assure, convey and confirm
unto the Trustee any property subject or required to be subjected to the lien of
this Indenture (including, without limitation, any and all actions necessary or
desirable as a result of changes in law or regulations) or to subject to the
lien of this Indenture any additional property;

          (f) to modify the restrictions on and procedures for resales and other
transfers of Notes to reflect any changes in applicable law or regulation (or
the interpretation thereof) or to


                                      -182-

<PAGE>

enable the Issuer and the Co-Issuer to rely upon any exemption from registration
under the Securities Act, the Exchange Act or the Investment Company Act or to
remove restrictions on resale and transfer to the extent not required
thereunder;

          (g) to accommodate the issuance, if any, of Notes in global or
book-entry form through the facilities of the Depository or otherwise;

          (h) otherwise to correct any inconsistency or cure any ambiguity or
mistake;

          (i) to take any action commercially reasonably necessary or advisable
to prevent the Issuer from failing to qualify as a Qualified REIT Subsidiary or
to prevent the Issuer, the Holders of the Notes, the Holders of the Preferred
Shares or the Trustee from being subject to withholding or other taxes, fees or
assessments or otherwise subject to U.S. federal, state, local or foreign income
or franchise tax on a net income tax basis; and

          (j) to conform this Indenture to the provisions described in the
Offering Memorandum (or any supplement thereto).

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

          If any Class of Notes is Outstanding and rated by a Rating Agency, the
Trustee shall not enter into any such supplemental indenture unless the Rating
Agency Condition has been satisfied, the notice of which may be in electronic
form, and, so long as MBIA is deemed to be the Controlling Class hereunder, MBIA
consents. At the cost of the Issuer, for so long as any Class of Notes shall
remain Outstanding and is rated by a Rating Agency, the Trustee shall provide to
such Rating Agency a copy of any proposed supplemental indenture at least 15
days prior to the execution thereof by the Trustee, and, for so long as such
Notes are Outstanding and so rated, request written confirmation, which may be
in electronic form, that such Rating Agency will not, as a result of such
supplemental indenture, cause the rating of any such Class of Notes to be
reduced or withdrawn, and, as soon as practicable after the execution by the
Trustee, the Issuer and the Co-Issuer of any such supplemental indenture,
provide to such Rating Agency a copy of the executed supplemental indenture.

          The Trustee shall not enter into any such supplemental indenture if
(i) as a result of such supplemental indenture, the interests of any Holder of
Securities would be materially and adversely affected thereby, unless the
Majority of each and every Class of Notes or the Preferred Shares so affected
have approved such supplemental indenture or (ii) such action would adversely
affect the tax treatment of the Holders of the Notes as described in the
Offering Memorandum under the heading "Certain U.S. Federal Income Tax
Considerations" to any material extent or otherwise cause any of the statements
described in the Offering Memorandum under the heading "Certain U.S. Federal
Income Tax Considerations" to be inaccurate or incorrect to any material extent.
The Trustee shall be entitled to rely upon (i) the receipt of notice, which may
be in electronic form, that the Rating Agency Condition has been satisfied and


                                      -183-

<PAGE>

(ii) receipt of an Officer's Certificate of the Collateral Manager in
determining whether or not the Holders of Securities would be adversely affected
by such change (after giving notice of such change to the Holders of
Securities). Such determination shall be conclusive and binding on all present
and future Holders of Securities. The Trustee shall not be liable for any such
determination made in good faith and in reliance upon such Officer's
Certificate.

          Furthermore, the Trustee shall not enter into any such supplemental
indenture unless the Trustee has received an Opinion of Counsel from Cadwalader,
Wickersham & Taft LLP or other nationally recognized U.S. tax counsel
experienced in such matters that the proposed supplemental indenture will not
cause the Issuer to (x) fail to be treated as a Qualified REIT Subsidiary or (y)
otherwise be treated as a foreign corporation that is engaged in a trade or
business in the United States for U.S. federal income tax purposes.

          Section 8.2 Supplemental Indentures with Consent of Securityholders.

          Except as set forth below, the Trustee and the Co-Issuers may enter
into one or more indentures supplemental hereto to add any provisions to, or
change in any manner or eliminate any of the provisions of, this Indenture or
modify in any manner the rights of the Holders of any Class of Notes or the
Preferred Shares under this Indenture only (x) with the written consent of (a)
the Holders of a Majority in Aggregate Outstanding Amount of the Notes of each
Class materially and adversely affected thereby (excluding any Notes owned by
the Collateral Manager or any of its Affiliates, or by any accounts managed by
them) and the Holder of Preferred Shares if materially and adversely affected
thereby, by Act of said Securityholders delivered to the Trustee and the
Co-Issuers, and (b) the consent of each Hedge Counterparty (to the extent
required by the related Hedge Agreement), and (c) the Class A-1AR Note Agent if
it is materially and adversely affected thereby, and (y) subject to satisfaction
of the Rating Agency Condition, notice of which may be in electronic form, and,
so long as MBIA is deemed to be the Controlling Class hereunder, the consent of
MBIA. Unless the Trustee is notified (after giving 15 Business Days' notice of
such change to the Holders of each Class of Notes, the Holder of the Preferred
Shares, each Hedge Counterparty and the Class A-1AR Note Agent) by Holders of a
Majority in Aggregate Outstanding Amount of the Notes of any Class (excluding
any Notes owned by the Collateral Manager or any of its Affiliates, or by any
accounts managed by them) that such Class of Notes will be materially and
adversely affected by the proposed supplemental indenture (and upon receipt of
an Officer's Certificate of the Collateral Manager), the interests of such Class
and the interests of the Preferred Shares will be deemed not to be materially
and adversely affected by such proposed supplemental indenture and the Trustee
will be permitted to enter into such supplemental indenture. Such determinations
shall be conclusive and binding on all present and future Noteholders. The
consent of the Holders of the Preferred Shares shall be binding on all present
and future Holders of the Preferred Shares. The Trustee shall not be liable for
any such determination made in good faith and in reliance upon an Officer's
Certificate of the Collateral Manager.

          Without the consent of (w) each Hedge Counterparty (except to the
extent required by the related Hedge Agreement), (x) all of the Holders of each
Outstanding Class of Notes adversely affected, and in each such case subject to
satisfaction of the Rating Agency Condition, notice of which may be in
electronic form, (y) all of the Holders of the Preferred


                                      -184-

<PAGE>

Shares adversely affected thereby and (z) MBIA, so long as MBIA is deemed to be
the Controlling Class hereunder, no supplemental indenture may:

          (a) change the Stated Maturity of the principal of or the due date of
any installment of interest on any Note or the Class A-1AR Commitment Fee,
reduce the principal amount thereof or the Note Interest Rate thereon or the
Redemption Price with respect to any Note, change the date of any scheduled
distribution on the Preferred Shares, or the Redemption Price with respect
thereto, change the earliest date on which any Note may be redeemed at the
option of the Issuer, change the provisions of this Indenture that apply the
proceeds of any Assets to the payment of principal of or interest on Notes or of
distributions to the Preferred Shares Paying Agent for the payment of
distributions in respect of the Preferred Shares or change any place where, or
the coin or currency in which, any Note or the principal thereof or interest
thereon is payable, or impair the right to institute suit for the enforcement of
any such payment on or after the Stated Maturity thereof (or, in the case of
redemption, on or after the applicable Redemption Date);

          (b) reduce the percentage of the Aggregate Outstanding Amount of
Holders of Notes of each Class or the Notional Amount of Preferred Shares of the
Holders thereof whose consent is required for the authorization of any such
supplemental indenture or for any waiver of compliance with certain provisions
of this Indenture or certain Defaults hereunder or their consequences provided
for in this Indenture;

          (c) impair or adversely affect the Assets except as otherwise
permitted in this Indenture;

          (d) 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 the Assets or
terminate such lien on any property at any time subject hereto or deprive the
Holder of any Note, or the Holder of any Preferred Share as an indirect
beneficiary, of the security afforded to such Holder by the lien of this
Indenture;

          (e) reduce the percentage of the Aggregate Outstanding Amount of
Holders of Notes of each Class whose consent is required to request the Trustee
to preserve the Assets or rescind the Trustee's election to preserve the Assets
pursuant to Section 5.5 or to sell or liquidate the Assets pursuant to Section
5.4 or 5.5 hereof;

          (f) modify any of the provisions of this Section 8.2, except to
increase any percentage of Outstanding Notes whose holders' consent is required
for any such action or to provide that other provisions of this Indenture cannot
be modified or waived without the consent of the Holder of each Outstanding Note
affected thereby;

          (g) modify the definition of the term "Outstanding" or the provisions
of Section 11.1 or Section 13.1 hereof; or

          (h) modify any of the provisions of this Indenture in such a manner as
to affect the calculation of the amount of any payment of interest or principal
on any Note or the payment of the Class A-1AR Commitment Fee on any Payment Date
or of distributions to the Preferred Shares Paying Agent for the payment of
distributions in respect of the Preferred Shares


                                      -185-

<PAGE>

on any Payment Date (or any other date) or to affect the rights of the Holders
of Securities to the benefit of any provisions for the redemption of such
Securities contained herein;

provided, however, that no supplemental indenture may reduce the permitted
minimum denominations of the Notes or modify any provisions regarding limited
recourse or non-petition covenants with respect to the Issuer and the Co-Issuer.

          If any Class of Notes is Outstanding and rated by a Rating Agency, the
Trustee shall not enter into any such supplemental indenture unless the Rating
Agency Condition is satisfied with respect thereto, the notice of which may be
in electronic form, and, so long as MBIA is deemed to be the Controlling Class
hereunder, MBIA consents. At the cost of the Issuer, for so long as any Class of
Notes shall remain Outstanding and is rated by a Rating Agency, the Trustee
shall provide to such Rating Agency a copy of any proposed supplemental
indenture at least 15 days prior to the execution thereof by the Trustee, and,
for so long as such Notes are Outstanding and so rated, request written
confirmation, which may be in electronic form, that such Rating Agency will not,
as a result of such supplemental indenture, cause the rating of any such Class
of Notes to be reduced or withdrawn.

          The Trustee shall be entitled to rely upon an Opinion of Counsel
provided by and at the expense of the party requesting such supplemental
indenture in determining whether or not the Holders of Securities would be
adversely affected by such change (after giving notice of such change to the
Holders of Securities). Such determination shall be conclusive and binding on
all present and future Holders of Securities. The Trustee shall not be liable
for any such determination made in good faith and in reliance upon an Opinion of
Counsel delivered to the Trustee as described in Section 8.3 hereof.

          It shall not be necessary for any Act of Securityholders under this
Section 8.2 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 Issuer, the Co-Issuer and the
Trustee of any supplemental indenture pursuant to this Section 8.2, the Trustee,
at the expense of the Issuer, shall mail to the Securityholders, the Class A-1AR
Note Agent, each Hedge Counterparty, the Preferred Shares Paying Agent, the
Collateral Manager, and, so long as the Notes are Outstanding and so rated, each
Rating Agency a copy thereof based on an outstanding rating. Any failure of the
Trustee to publish or mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

          Section 8.3 Execution of Supplemental Indentures.

          In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article 8 or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to
receive, and 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 and that all conditions precedent thereto have been
satisfied. The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise. The


                                      -186-

<PAGE>

Collateral Manager will be bound to follow any amendment or supplement to this
Indenture of which it has received written notice at least ten Business Days
prior to the execution and delivery of such amendment or supplement; provided,
however, that with respect to any amendment or supplement to this Indenture
which may, in the judgment of the Collateral Manager adversely affect the
Collateral Manager, the Collateral Manager shall not be bound (and the Issuer
agrees that it will not permit any such amendment to become effective) unless
the Collateral Manager gives written consent to the Trustee and the Issuer to
such amendment. The Issuer and the Trustee shall give written notice to the
Collateral Manager of any amendment made to this Indenture pursuant to its
terms. In addition, the Collateral Manager's written consent shall be required
prior to any amendment to this Indenture by which it is adversely affected.

          Section 8.4 Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under this Article 8,
this Indenture shall be modified in accordance therewith, such supplemental
indenture shall form a part of this Indenture for all purposes and every Holder
of Notes theretofore and thereafter authenticated and delivered hereunder, and
every Holder of Preferred Shares, shall be bound thereby.

          Section 8.5 Reference in Notes to Supplemental Indentures.

          Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article 8 may, and if required by the
Trustee shall, bear a notice in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Issuer and the Co-Issuer
shall so determine, new Notes, so modified as to conform in the opinion of the
Trustee and the Issuer and the Co-Issuer to any such supplemental indenture, may
be prepared and executed by the Issuer and the Co-Issuer and authenticated and
delivered by the Trustee in exchange for Outstanding Notes.

          Section 8.6 Certain Consents Required for all Supplemental Indentures.

          Notwithstanding anything in this Article 8 to the contrary, so long as
MBIA is deemed to be the Controlling Class hereunder, the Issuer, the Co-Issuer
and the Trustee shall not enter into any supplemental indenture without
obtaining the consent of MBIA (such consent not to be unreasonably withheld or
delayed); provided that, if MBIA does not object to such supplemental indenture
within 14 days after notice is given and all applicable conditions set forth in
this Section 8 are satisfied, such Holders will be deemed to have consented to
such supplemental indenture.

                 REDEMPTION OF SECURITIES; REDEMPTION PROCEDURES

          Section 9.1 Clean-up Call; Tax Redemption and Optional Redemption.

          (a) The Notes may be redeemed by the Issuer at the option of and at
the direction of the Collateral Manager (such redemption, a "Clean-up Call"), in
whole but not in


                                      -187-

<PAGE>

part, at a price equal to the applicable Redemption Prices on any Payment Date
(the "Clean-up Call Date") on or after the Payment Date on which the Aggregate
Outstanding Amount of the Notes has been reduced to 10% of the Aggregate
Outstanding Amount of the Notes on the Closing Date; provided that any payments
due and payable upon a termination of each Hedge Agreement will be made on the
Clean-up Call Date in accordance with the terms thereof and this Indenture;
provided, further, that the funds available to be used for such Clean-up Call
will be sufficient to pay the Total Redemption Price.

          (b) The Notes and the Preferred Shares shall be redeemable, in whole
but not in part, by Act of a Majority of the Preferred Shares delivered to the
Trustee, on the Payment Date (the "Tax Redemption Date") following the
occurrence of a Tax Event if the Tax Materiality Condition is satisfied at a
price equal to the applicable Redemption Prices (such redemption, a "Tax
Redemption"); provided that any payments due and payable upon a termination of
each Hedge Agreement will be made in accordance with the terms thereof and this
Indenture; provided, further, that the funds available to be used for such Tax
Redemption will be sufficient to pay the Total Redemption Price. Upon the
occurrence of a Tax Event, the Issuer and the Co-Issuer, at the direction of the
Collateral Manager shall provide written notice thereof to the Trustee, the
Irish Paying Agent (for so long as any Notes (other than the Class A-1AR Notes)
are listed on the Irish Stock Exchange), each Hedge Counterparty, the Class
A-1AR Note Agent and each Rating Agency.

          (c) The Notes and the Preferred Shares shall be redeemable, in whole
but not in part, at a price equal to the applicable Redemption Prices, on any
Payment Date after the end of the Non-call Period, at the direction of the
Issuer (such redemption, an "Optional Redemption") by Act of a Majority of the
Preferred Shares delivered to the Trustee; provided, however, that any payments
due and payable upon a termination of each Hedge Agreement will be made in
accordance with the terms thereof and this Indenture; provided, further, that
the funds available to be used for such Optional Redemption will be sufficient
to pay the Total Redemption Price. Notwithstanding anything herein to the
contrary, the Issuer shall not sell any Asset to the Collateral Manager or any
Affiliate of the Collateral Manager other than ARMS Equity in connection with an
Optional Redemption.

          (d) The election by the Collateral Manager to redeem the Notes
pursuant to a Clean-up Call shall be evidenced by an Officer's Certificate from
the Collateral Manager directing the Trustee to make the payment to the Paying
Agent of the applicable Redemption Price of all of the Notes to be redeemed from
funds in the Payment Account in accordance with the Priority of Payments. In
connection with a Tax Redemption, the occurrence of a Tax Event and satisfaction
of the Tax Materiality Condition shall be evidenced by an Issuer Order from the
Issuer or from the Collateral Manager on behalf of the Issuer certifying that
such conditions for a Tax Redemption have occurred. The election by the
Collateral Manager to redeem the Notes pursuant to an Optional Redemption shall
be evidenced by an Officer's Certificate from the Collateral Manager on behalf
of the Issuer certifying that the conditions for an Optional Redemption have
occurred.

          (e) A redemption pursuant to Section 9.1(a), 9.1(b) or 9.1(c) shall
not occur unless (i) at least six Business Days before the scheduled Redemption
Date, (A) the Collateral Manager shall have certified to the Trustee that the
Collateral Manager, on behalf of the Issuer,


                                      -188-

<PAGE>

has entered into a binding agreement or agreements with (1) one or more
financial institutions whose long-term unsecured debt obligations (other than
such obligations whose rating is based on the credit of a person other than such
institution) have a credit rating from each Rating Agency at least equal to the
highest rating of any Notes then Outstanding or whose short-term unsecured debt
obligations have a credit rating of "P-1" by Moody's (as long as the term of
such agreement is 90 days or less) and "A-1" by S&P or (2) one or more
Affiliates of the Collateral Manager, to sell all or part of the Pledged
Obligations not later than the Business Day immediately preceding the scheduled
Redemption Date or (B) the Trustee shall have received written confirmation that
the method of redemption satisfies the Rating Agency Condition and so, long as
MBIA is deemed to be the Controlling Class hereunder, MBIA has consented (ii)
the related Sale Proceeds (in immediately available funds), together with all
other available funds (including proceeds from the sale of the Assets, Eligible
Investments maturing on or prior to the scheduled Redemption Date, all amounts
in the Collection Accounts and available Cash), shall be an aggregate amount
sufficient to pay all amounts, payments, fees and expenses in accordance with
the Priority of Payments due and owing on such Redemption Date.

          Section 9.2 Auction Call Redemption.

          (a) During the period from and including the Payment Date occurring in
January 2017 and to but not including the first Payment Date on which the
Clean-up Call may be exercised (the "Auction Call Period"), the Securities shall
be redeemed by the Issuer, in whole but not in part, at their applicable
Redemption Prices if a Successful Auction is completed (such redemption, an
"Auction Call Redemption"); provided that any payments due and payable upon a
termination of each Hedge Agreement will be made on the Auction Call Redemption
Date in accordance with the terms thereof and this Indenture; and provided,
further, that the funds available to be used for such Auction Call Redemption
will be sufficient to pay the Total Redemption Price. An Auction Call Redemption
may occur only on a Payment Date occurring in January or April during the
Auction Call Period (such Payment Date, the "Auction Call Redemption Date").

          (b) The Trustee shall sell and transfer the Collateral Debt Securities
to the highest bidder for all of the Collateral Debt Securities (or to each
highest bidder for one or more (but not all) of the Collateral Debt Securities),
at the Auction, as long as:

          (i) the Auction has been conducted in accordance with the Auction
     Procedures, as evidenced by a certification of the Collateral Manager;

          (ii) at least one bidder delivers to the Collateral Manager a bid
     (which bid may be based upon a fixed spread above or below a generally
     recognized price index) for (x) the purchase of all of the Collateral Debt
     Securities or (y) the purchase of each Collateral Debt Security (which bid
     may be for one or more (but not all) of the Collateral Debt Securities);

          (iii) based on the Collateral Manager's certification to the Trustee
     of the amount of the Cash purchase price of each bid, the Trustee, in
     consultation with the Collateral Manager, determines that the Highest
     Auction Price would result in a Cash purchase price for the Collateral Debt
     Securities which, together with the balance of all


                                      -189-

<PAGE>

     Eligible Investments and Cash in the Collection Accounts, the Payment
     Account and the Expense Account, will be at least equal to the Total
     Redemption Price; and

          (iv) each bidder who offered the Highest Auction Price for all of the
     Collateral Debt Securities or for one or more of the Collateral Debt
     Securities enters into a written agreement with the Issuer (which the
     Issuer shall execute if the conditions set forth in clauses (i) through
     (iii) above are satisfied) obligating the highest bidder for all of the
     Collateral Debt Securities (or the highest bidder for one or more (but not
     all) of the Collateral Debt Securities) to purchase all (either
     individually or together with other bidders, as applicable) of the
     Collateral Debt Securities with the closing of such purchase (and full
     payment in Cash to the Trustee) to occur on or before the 10th Business Day
     prior to the scheduled Redemption Date.

          (c) If any of the foregoing conditions is not met with respect to any
Auction, or if the highest bidder or the Collateral Manager, as the case may be,
fails to pay the purchase price on or before the sixth Business Day following
the relevant Auction Date, (i) the Auction Call Redemption shall not occur on
the Payment Date following the relevant Auction Date, (ii) the Trustee shall
give notice of the withdrawal pursuant to Section 9.3, (iii) subject to
subclause (iv) below, the Trustee shall decline to consummate such sale and
shall not solicit any further bids or otherwise negotiate any further sale of
Collateral Debt Securities in relation to such Auction and (iv) unless the Notes
and the Preferred Shares are redeemed in full prior to the next succeeding
Auction Date, or the Collateral Manager notifies the Trustee that market
conditions are such that such Auction is not likely to be successful, the
Trustee shall conduct another Auction on the next succeeding Auction Date.

          Section 9.3 Notice of Redemption.

          (a) In connection with an Optional Redemption, a Clean-up Call or a
Tax Redemption pursuant to Section 9.1 or an Auction Call Redemption pursuant to
Section 9.2, the Trustee on behalf of the Issuer and the Co-Issuer shall (i) set
the applicable Record Date and (ii) at least 45 days prior to the proposed
Redemption Date, notify the Collateral Manager, each Hedge Counterparty, the
Class A-1AR Note Agent, the Rating Agencies and each Preferred Shareholder at
such Preferred Shareholder's address in the register maintained by the Share
Registrar, of such proposed Redemption Date, the applicable Record Date, the
principal amount of Notes to be redeemed on such Redemption Date and the
Redemption Price of such Notes in accordance with Section 9.1 or Section 9.2.
The Redemption Price shall be determined no earlier than 60 days prior to the
proposed Redemption Date.

          (b) Any such notice of an Auction Call Redemption, an Optional
Redemption, a Clean-up Call or a Tax Redemption may be withdrawn by the Issuer
and the Co-Issuer at the direction of the Collateral Manager up to the fourth
Business Day prior to the scheduled Redemption Date by written notice to the
Trustee, the Class A-1AR Note Agent, the Irish Paying Agent (for so long as any
Notes (other than the Class A-1AR Notes) are listed on the Irish Stock
Exchange), the Class A-1AR Note Agent, each Hedge Counterparty, to each Holder
of Notes to be redeemed, and the Collateral Manager only if (i) in the case of
an Optional Redemption, a Clean-up Call or a Tax Redemption the Collateral
Manager is unable to deliver the sale agreement or agreements or certifications
referred to in Section 9.1(e), as the case may be or (ii)


                                      -190-

<PAGE>

in the case of an Auction Call Redemption, the Auction is unable to be
consummated pursuant to the Auction Procedures.

          Section 9.4 Notice of Redemption or Maturity by the Issuer.

          Notice of redemption pursuant to Section 9.1, Section 9.2 or the
Maturity of any Notes shall be given by first class mail, postage prepaid,
mailed not less than ten Business Days (or four Business Days where the notice
of an Auction Call Redemption, an Optional Redemption, a Clean-up Call or a Tax
Redemption is withdrawn pursuant to Section 9.3(b)) prior to the applicable
Redemption Date or Maturity, to each Holder of Notes to be redeemed, at its
address in the Notes Register.

          All notices of redemption shall state:

          (a) the applicable Redemption Date;

          (b) the applicable Redemption Price;

          (c) that all the Notes are being paid in full and all Class A-1AR
Commitments shall terminate, and that interest on the Notes shall cease to
accrue on the Redemption Date specified in the notice; and

          (d) the place or places where such Notes to be redeemed in whole are
to be surrendered for payment of the Redemption Price which shall be the office
or agency of the Paying Agent as provided in Section 7.2.

          Notice of redemption shall be given by the Issuer and Co-Issuer, or at
their request, by the Trustee in their names, and at the expense of the Issuer.
Failure to give notice of redemption, or any defect therein, to any Holder of
any Note shall not impair or affect the validity of the redemption of any other
Notes. In addition, so long as any Notes (other than the Class A-1AR Notes) are
listed on the Irish Stock Exchange, notice of redemption or Maturity shall be
published in the Irish Stock Exchange's Daily Official List or as otherwise
required by the rules of the Irish Stock Exchange not less than ten Business
Days prior to the applicable Redemption Date or Maturity.

          Section 9.5 Notes Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, the Notes to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified and all Class A-1AR Commitments shall terminate on such
date, and from and after the Redemption Date (unless the Issuer shall Default in
the payment of the Redemption Price and accrued interest thereon) the Notes
shall cease to bear interest on the Redemption Date. Upon final payment on a
Note to be redeemed, the Holder shall present and surrender such Note at the
place specified in the notice of redemption on or prior to such Redemption Date;
provided, however, that if there is delivered to the Issuer, the Co-Issuer and
the Trustee such security or indemnity as may be required by them to hold each
of them harmless (an unsecured indemnity agreement delivered to the Issuer, the
Co-Issuer and the Trustee by an institutional investor with a net worth of at
least $200,000,000 being deemed to satisfy such security or indemnity


                                      -191-

<PAGE>

requirement) and an undertaking thereafter to surrender such Note, then, in the
absence of notice to the Issuer, the Co-Issuer and the Trustee that the
applicable Note has been acquired by a bona fide purchaser, such final payment
shall be made without presentation or surrender. Payments of interest on Notes
of a Class so to be redeemed whose Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Notes, or one or more predecessor
Notes, registered as such at the close of business on the relevant Record Date
according to the terms and provisions of Section 2.7(n).

          If any Note called for redemption shall not be paid upon surrender
thereof for redemption, the principal thereof shall, until paid, bear interest
from the Redemption Date at the applicable Note Interest Rate for each
successive Interest Accrual Period the Note remains Outstanding.

          Section 9.6 Mandatory Redemption.

          On any Payment Date on which any of the Coverage Tests applicable to
any Class of Notes is not satisfied as of the most recent Measurement Date on or
after the Effective Date, the Notes shall be redeemed (a "Mandatory
Redemption"), first from Interest Proceeds, net of amounts set forth in Section
11.1(a)(i)(1) through (5), and then from Principal Proceeds, net of amounts set
forth in clause (1) of Section 11.1(a)(ii), in an amount necessary, and only to
the extent necessary, to cause each of the Coverage Tests to be satisfied (and
the Class A-1AR Commitments will be reduced simultaneously as described in
Section 18.1(e)); provided that, to the extent that the sum of all Class A-1AR
Commitments is reduced to an amount less than the Minimum Class A-1AR
Commitment, a portion of the Interest Proceeds and/or Principal Proceeds that
are available for distribution shall be deposited into the Delayed Funding
Obligations Account until the Aggregate Class A-1AR Undrawn Amount equals the
Minimum Class A-1AR Commitment. Further, each Hedge Agreement will be terminated
in part in accordance with the terms thereof and any payments due and payable on
the Hedge Agreement in connection with the termination of the Hedge Agreement
will be made on such Payment Date in accordance with the terms thereof and this
Indenture, including satisfaction of the Rating Agency Condition and so long as
MBIA is deemed to be the Controlling Class hereunder, the consent of MBIA. Such
Principal Proceeds and Interest Proceeds shall be applied to each of the
Outstanding Classes of Notes in accordance with its relative seniority in
accordance with the Priority of Payments. On or promptly after such Mandatory
Redemption, the Issuer and the Co-Issuer shall certify or cause to be certified
to each of the Rating Agencies and the Trustee whether the Coverage Tests have
been met.

          Section 9.7 Special Amortization.

          The Notes may be amortized in part by the Issuer (at the election and
direction of the Collateral Manager) if, at any time during the Reinvestment
Period, the Collateral Manager has been unable to identify Collateral Debt
Securities that it determines would be appropriate and would meet the
Eligibility Criteria in sufficient amounts to permit the reinvestment of all or
a portion of the Principal Proceeds then on deposit in the Principal Collection
Account and the amounts on deposit in the Unused Proceeds Account in Substitute
Collateral Debt Securities. The Collateral Manager shall notify the Trustee, the
Issuer, the Co-Issuer, the Class A-1AR Note Agent, and each Hedge Counterparty
(if any) of such election (a "Special Amortization") and the


                                      -192-

<PAGE>

amount to be amortized (such amount, the "Special Amortization Amount"). On the
first Payment Date following the date on which such notice is given (so long as
such notice is given by the related Determination Date), the Special
Amortization Amount will be applied to amortize the Notes in accordance with the
Priority of Payments (x) on a pro rata basis (based on the Aggregate Outstanding
Amount of each Class) among all Classes of Notes (without regard to any
Capitalized Interest and assuming for purposes of the Class A-1A/A-1AR Pro Rata
Allocation, the Class A-1AR Notes are fully drawn, but allocating the amounts
between the Class A-1A Notes and the Class A-1AR Notes, as described in Section
11.1(a)(iii)), if each of the S&P Special Amortization Pro Rata Condition and
the Moody's Special Amortization Pro Rata Condition is satisfied with respect to
the related Payment Date and, so long as MBIA is deemed to be the Controlling
Class hereunder, MBIA otherwise consents, the Class A/B Par Value Test has not
failed to be satisfied on any prior Determination Date or (y) sequentially among
all Classes of Notes if (A) either the S&P Special Amortization Pro Rata
Condition or the Moody's Special Amortization Pro Rata Condition is not
satisfied with respect to the related Payment Date or, (B) so long as MBIA is
deemed to be the Controlling Class hereunder and MBIA does not otherwise
consent, the Class A/B Par Value Test has failed to be satisfied on any prior
Determination Date; provided that, in the case of the foregoing clause (B), if
the Class A/B Par Value Test has failed to be satisfied on any prior
Determination Date and, so long as MBIA is deemed to be the Controlling Class
hereunder, MBIA does not otherwise consent, the Issuer shall be entitled to cure
such failure (and effect pro rata amortizations thereafter, subject to
satisfaction of any other relevant conditions) by selling one Collateral Debt
Security in accordance with the relevant provisions of this Indenture to the
extent necessary so that the Class A/B Par Value Test is satisfied after such
sale; provided, further, however, if the Class A/B Par Value Test is failed on
any Determination Date thereafter, no pro rata Special Amortizations may be
effected thereafter. Notwithstanding the foregoing, all amounts representing
recoveries in respect of Defaulted Securities will be distributed sequentially
in any event, in accordance with Section 11.1(a)(ii)(9). In connection with any
Special Amortization, the Class A-1AR Commitments will be reduced simultaneously
as described in Section 18.1(e).

this Indenture, including all payments due on the Pledged Obligations in

          Section 10.2 Collection Accounts.

          (a) The Trustee shall, prior to the Closing Date, establish a
segregated trust account which shall be designated as the "Collection Account"
(which may be a subaccount of the Custodial Account) and shall consist of two
subaccounts, the "Interest Collection Account" and the "Principal Collection
Account" (collectively, the "Collection Accounts"), which shall be held in trust
in the name of the Trustee for the benefit of the Secured Parties, into which
Collection Accounts, as applicable, the Trustee shall from time to time deposit
(i) all amounts, if any, received by the Issuer pursuant to the Hedge Agreements
(other than amounts received by the Issuer by reason of an event of default or
termination event (each as defined in the related Hedge Agreement) or other
comparable event that are required, pursuant to Section 16.1(g) to be used for
the purchase by the Issuer of a replacement Hedge Agreement) and amounts held in
each Hedge Collateral Account pursuant to Section 16.1(e), (ii) all Sale
Proceeds (unless simultaneously reinvested in Substitute Collateral Debt
Securities, subject to the Reinvestment Criteria) and (iii) all Interest
Proceeds and all Principal Proceeds. In addition, the Issuer may, but under no
circumstances shall, be required to, deposit from time to time such Monies in
the Collection Accounts as it deems, in its sole discretion, to be advisable.
All Monies deposited from time to time in the Collection Accounts pursuant to
this Indenture shall be held by the Trustee as part of the Assets and shall be
applied to the purposes herein provided. The Collection Accounts shall remain at
all times with the Corporate Trust Office or a financial institution having a
long-term debt rating at least equal to "A-" or "A2," as applicable, or a
short-term debt rating at least equal to "A-1," "P-1" or "F1," as applicable.

          (b) All distributions of principal or interest received in respect of
the Assets, and any Sale Proceeds from the sale or disposition of a Collateral
Debt Security or other Assets received by the Trustee in Dollars shall be
immediately deposited into the Interest Collection Account or the Principal
Collection Account, as Interest Proceeds or Principal Proceeds, respectively
(unless, in the case of proceeds received from the sale or disposition of any
Assets, such proceeds are simultaneously reinvested pursuant to Section 10.2(d)
in Substitute Collateral Debt Securities, subject to the Reinvestment Criteria,
or in Eligible Investments). In addition, any amounts borrowed under the Class
A-1AR Notes in connection with a Special Amortization will be remitted to the
Principal Collection Account. Subject to Sections 10.2(d), 10.2(e) and 11.2, all
such property, together with any securities in which funds included in such
property are or will be invested or reinvested during the term of this
Indenture, and any income or other gain realized from such investments, shall be
held by the Trustee in the Collection Accounts as part of the Assets subject to
disbursement and withdrawal as provided in this Section 10.2. Subject to Section
10.2(e) by Issuer Order (which may be in the form of standing instructions), the
Issuer (or the Collateral Manager on behalf of the Issuer) shall at all times
direct the Trustee to, and, upon receipt of such Issuer Order, the Trustee
shall, invest all funds received into the Collection Accounts during a Due
Period, and amounts received in prior Due Periods and retained in the Collection
Accounts, as so directed in Eligible Investments having stated maturities no
later than the Business Day immediately preceding the next Payment Date. The
Trustee, within one Business Day after receipt of any Scheduled Distribution or
other proceeds in respect of the Assets which is not Cash, shall so notify the
Issuer and the Collateral Manager and the Issuer (or the Collateral Manager on
behalf of the Issuer) shall, within five Business Days of receipt of such notice
from the Trustee, sell such Scheduled Distribution or other non-Cash proceeds
for Cash in an arm's length transaction to a Person which is not an Affiliate of
the Issuer or the


                                      -194-

<PAGE>

Collateral Manager and deposit the proceeds thereof in the applicable Collection
Account for investment pursuant to this Section 10.2; provided, however, that
the Issuer (or the Collateral Manager on behalf of the Issuer) need not sell
such Scheduled Distributions or other non-Cash proceeds if it delivers an
Officer's Certificate to the Trustee certifying that such Scheduled
Distributions or other proceeds constitute Collateral Debt Securities or
Eligible Investments.

          (c) If prior to the occurrence of an Event of Default, the Issuer (or
the Collateral Manager on behalf of the Issuer) shall not have given any
investment directions pursuant to Section 10.2(b), the Trustee shall seek
instructions from the Issuer (or the Collateral Manager on behalf of the Issuer)
within three Business Days after transfer of such funds to the applicable
Collection Account. If the Trustee does not thereupon receive written
instructions from the Issuer (or the Collateral Manager on behalf of the Issuer)
within five Business Days after transfer of such funds to the applicable
Collection Account, it shall invest and reinvest the funds held in the
applicable Collection Account in one or more Eligible Investments described in
clause (ii) of the definition of Eligible Investments maturing no later than the
Business Day immediately preceding the next Payment Date. If after the
occurrence of an Event of Default, the Issuer (or the Collateral Manager on
behalf of the Issuer) shall not have given investment directions to the Trustee
pursuant to Section 10.2(b) for three consecutive days, the Trustee shall invest
and reinvest such Monies as fully as practicable in Eligible Investments
described in clause (ii) of the definition of Eligible Investments maturing not
later than the earlier of (i) 30 days after the date of such investment or (ii)
the Business Day immediately preceding the next Payment Date. All interest and
other income from such investments shall be deposited in the applicable
Collection Account, any gain realized from such investments shall be credited to
the applicable Collection Account, and any loss resulting from such investments
shall be charged to the applicable Collection Account. The Trustee shall not in
any way be held liable (except as a result of negligence, willful misconduct or
bad faith) by reason of any insufficiency of such applicable Collection Account
resulting from any loss relating to any such investment, except with respect to
investments in obligations of the Trustee or any Affiliate thereof.

          (d) During the Reinvestment Period (and thereafter to the extent
necessary to acquire Collateral Debt Securities pursuant to contracts entered
into during the Reinvestment Period), the Collateral Manager on behalf of the
Issuer may by Issuer Order direct the Trustee to, and upon receipt of such
Issuer Order the Trustee shall, reinvest Principal Proceeds in Collateral Debt
Securities selected by the Collateral Manager as permitted under and in
accordance with the requirements of Article 12 and such Issuer Order.

          (e) The Trustee shall transfer to the Payment Account for application
pursuant to Section 11.1(a) and in accordance with the calculations and the
instructions contained in the Notes Valuation Report prepared by the Trustee on
behalf of the Issuer pursuant to Section 10.11(e), on or prior to the Business
Day prior to each Payment Date, any amounts then held in the Collection Accounts
other than (i) Interest Proceeds or Principal Proceeds received after the end of
the Due Period with respect to such Payment Date and (ii) amounts that the
Issuer is entitled to reinvest in accordance with Section 12.2 and which the
Issuer so elects to reinvest in accordance with the terms of this Indenture,
except that, to the extent that Principal Proceeds in the Principal Collection
Account as of such date are in excess of the amounts required to be applied
pursuant to the Priority of Payments up to and including the next Payment Date
as shown in the Notes Valuation Report with respect to such Payment Date, the
Issuer may


                                      -195-

<PAGE>

direct the Trustee to retain such excess amounts in the Principal Collection
Account and not to transfer such excess amounts to the Payment Account and the
Trustee shall do so.

          Section 10.3 Payment Account.

          The Trustee shall, prior to the Closing Date, establish a single,
segregated trust account which shall be designated as the "Payment Account,"
which shall be held in trust for the benefit of the Secured Parties and over
which the Trustee shall have exclusive control and the sole right of withdrawal.
Any and all funds at any time on deposit in, or otherwise to the credit of, the
Payment Account shall be held in trust by the Trustee for the benefit of the
Secured Parties. Except as provided in Sections 11.1 and 11.2, the only
permitted withdrawal from or application of funds on deposit in, or otherwise to
the credit of, the Payment Account shall be (i) to pay the interest on and the
principal of the Notes and make other payments in respect of the Notes in
accordance with their terms and the provisions of this Indenture, (ii) to pay
the Preferred Shares Paying Agent for deposit into the Preferred Share
Distribution Account for distributions to the Preferred Shareholders in
accordance with the terms and the provisions of the Preferred Shares Paying
Agency Agreement, (iii) upon Issuer Order, to pay other amounts specified
therein, and (iv) otherwise to pay amounts payable pursuant to and in accordance
with the terms of this Indenture, each in accordance with the Priority of
Payments. The Trustee agrees to give the Issuer and the Co-Issuer immediate
notice if it becomes aware that the Payment Account or any funds on deposit
therein, or otherwise to the credit of the Payment Account, shall become subject
to any writ, order, judgment, warrant of attachment, execution or similar
process. Neither the Issuer nor the Co-Issuer shall have any legal, equitable or
beneficial interest in the Payment Account other than in accordance with the
Priority of Payments. The Payment Account shall remain at all times with the
Corporate Trust Office or a financial institution having a long-term debt rating
by each Rating Agency at least equal to "A-" or "A2," as applicable, or a
short-term debt rating by each Rating Agency at least equal to "A-1," "P-1" or
"F1," as applicable. Amounts in the Payment Account shall not be invested.

          Section 10.4 Unused Proceeds Account.

          (a) The Trustee shall prior to the Closing Date establish a single,
segregated trust account which shall be designated as the "Unused Proceeds
Account" which shall be held in trust in the name of the Trustee for the benefit
of the Secured Parties, into which the amount specified in Section 3.2(g) shall
be deposited. All Monies deposited from time to time in the Unused Proceeds
Account pursuant to this Indenture, including, without limitation, any amounts
transferred to the Unused Proceeds Account pursuant to Section 10.6(c), shall be
held by the Trustee as part of the Assets and shall be applied to the purposes
herein provided.

          (b) The Trustee agrees to give the Issuer immediate notice if it
becomes aware that the Unused Proceeds Account or any funds on deposit therein,
or otherwise to the credit of the Unused Proceeds Account, shall become subject
to any writ, order, judgment, warrant of attachment, execution or similar
process. The Unused Proceeds Account shall remain at all times with the
Corporate Trust Office or a financial institution having a long-term debt rating
by each Rating Agency at least equal to "A-" or "A2," as applicable, or a
short-term debt rating at least equal to "A-1," "P-1" or "F1," as applicable.

          (c) During the Reinvestment Period, amounts on deposit in the Unused
Proceeds Account may or shall be designated by the Collateral Manager as Special
Amortization Amounts to be included as Principal Proceeds pursuant to Section
9.7. If the Aggregate Principal Balance (including the Aggregate Class A-1AR
Undrawn Amount) of the Collateral Debt Securities exceeds the Minimum Ramp-Up
Amount on the Effective Date, amounts remaining on deposit in the Unused
Proceeds Account at the end of the Ramp-Up Period (following receipt of Rating
Confirmation with respect to the Effective Date) not to exceed an amount equal
to 5% of the Deposit may, at the option of the Collateral Manager, be designated
as Interest Proceeds. Any such election will be made on a one-time basis and
must be made by written notice to the Trustee no later than the 20th Business
Day after the Effective Date, which notice shall set forth any such amounts in
the Unused Proceeds Account so designated (and any interest or earnings
thereon). Upon receipt of such notice, the Trustee shall transfer such amount to
the Interest Collection Account (for subsequent transfer to the Payment
Account), which will be treated as Interest Proceeds and applied in accordance
with the Priority of Payments. Any amounts remaining in the Unused Proceeds
Account on the 20th Business Day after the Effective Date, to the extent not
designated as Interest Proceeds and provided a Rating Confirmation Failure has
not occurred, shall be transferred by the Trustee to the Principal Collection
Account (for subsequent transfer to the Payment Account) and treated as
Principal Proceeds and applied in accordance with the Priority of Payments.

          (d) If a Rating Confirmation Failure occurs, upon receipt of notice
from the Collateral Manager pursuant to Section 7.18, the Trustee shall transfer
amounts in the Unused Proceeds Account to the Payment Account for application on
the immediately following Payment Date to pay principal of the Notes, first, to
the payment of principal of the Class A-1 Notes as described in Section
11.1(a)(iii), second, to the payment of principal of the Class A-2 Notes, third,
to the payment of principal of the Class B Notes, fourth, to the payment of
principal of the Class C Notes, fifth, to the payment of principal of the Class
D Notes, sixth, to the payment of principal of the Class E Notes, seventh, to
the payment of principal of the Class F Notes, eighth, to the payment of
principal of the Class G Notes and ninth, to the payment of principal of the
Class H Notes, in each case until the ratings assigned on the Closing Date to
each Class of Notes have been reinstated or such Class has been paid in full.
Any excess amount shall be treated as Principal Proceeds and applied in
accordance with the Priority of Payments. If no Rating Confirmation Failure
occurs, to the extent the Collateral Manager has not identified such amounts as
Interest Proceeds pursuant to Section 10.4(c), the Trustee shall transfer the
amounts on deposit in the Unused Proceeds Account to the Principal Collection
Account, and such amounts will be treated as Principal Proceeds and applied in
accordance with the Priority of Payments.

          (e) During the Ramp-Up Period, the Issuer (or the Collateral Manager
on behalf of the Issuer) may by Issuer Order direct the Trustee to, and upon
receipt of such Issuer Order the Trustee shall, apply amounts on deposit in the
Unused Proceeds Account to acquire Collateral Debt Securities selected by the
Collateral Manager as permitted under and in accordance with the requirements of
Section 7.17 and such Issuer Order.

          (f) To the extent not applied pursuant to Section 7.17, the Collateral
Manager, on behalf of the Issuer, may direct the Trustee to, and upon such
direction the Trustee shall, invest all funds in the Unused Proceeds Account in
Eligible Investments designated by the


                                      -197-

<PAGE>

Collateral Manager. All interest and other income from such investments shall be
deposited in the Unused Proceeds Account, any gain realized from such
investments shall be credited to the Unused Proceeds Account, and any loss
resulting from such investments shall be charged to the Unused Proceeds Account.
The Trustee shall not in any way be held liable (except as a result of
negligence, willful misconduct or bad faith) by reason of any insufficiency of
the Unused Proceeds Account resulting from any loss relating to any such
investment, except with respect to investments in obligations of the Trustee or
any Affiliate thereof. If the Trustee does not receive investment instructions
from an Authorized Officer of the Collateral Manager, the Trustee shall invest
funds received in the Unused Proceeds Account in Eligible Investments of the
type described in clause (ii) of the definition thereto.

          Section 10.5 Interest Reserve Account.

          The Trustee shall prior to the Closing Date establish a single,
segregated trust account which shall be designated as the "Interest Reserve
Account" which shall be held in trust in the name of the Trustee for the benefit
of the Secured Parties. On the Closing Date, the Trustee shall deposit into the
Interest Reserve Account an amount equal to $500,000 from the net proceeds
received by the Issuer on such date from the issuance of Securities. Funds on
deposit in the Interest Reserve Account will be withdrawn on any Payment Date,
provided the Trustee is given notice thereof by the related Determination Date,
for application as Interest Proceeds, in the sole discretion of the Collateral
Manager. In addition, funds in the Interest Reserve Account may be invested in
Eligible Investments as designated by the Collateral Manager. If the Trustee
does not receive investment instructions from an Authorized Officer of the
Collateral Manager, the Trustee shall invest funds received in the Interest
Reserve Account in Eligible Investments of the type described in clause (ii) of
the definition thereto.

          Section 10.6 Delayed Funding Obligations Account.

          (a) The Trustee shall prior to the Closing Date establish a single,
segregated trust account (the "Delayed Funding Obligations Account") which shall
be held in trust for the benefit of the Secured Parties, into which Delayed
Funding Obligations Account the Trustee shall deposit funds for any additional
funding commitments of the Issuer under any Delayed Draw Term Loans included in
the Collateral Debt Securities. All amounts in the Delayed Funding Obligations
Account shall be deposited in overnight funds in Eligible Investments and
released to fulfill such commitments. If a Delayed Draw Term Loan is sold or
otherwise disposed before the full commitment thereunder has been drawn, or if
excess funds remain following the termination of the funding obligation giving
rise to the deposit of such funds in the Delayed Funding Obligations Account,
such Eligible Investments on deposit in the Delayed Funding Obligations Account
for the purpose of fulfilling such commitment shall be transferred to the
Principal Collection Account as Principal Proceeds. The Delayed Funding
Obligations Account shall remain at all times with the Corporate Trust Office or
a financial institution having a long-term debt rating from each Rating Agency
at least equal to "A-" or "A2," as applicable, or a short-term debt rating at
least equal to "A-1," "P-1" or "F1," as applicable.

          (b) Except as provided in Section 10.6(c) below, funds in the Delayed
Funding Obligations Account shall be available solely to fulfill any additional
funding commitments of the Issuer under any Delayed Draw Term Loans included in
the Collateral Debt


                                      -198-

<PAGE>

Securities. Upon the purchase of any Collateral Debt Security that is a Delayed
Draw Term Loan, the Collateral Manager shall direct the Trustee to deposit
Principal Proceeds into the Delayed Funding Obligations Account in an amount
equal to the excess, if any, of the sum of (x) the aggregate amount of the
Issuer's remaining future funding obligations with respect to such Delayed Draw
Term Loan and (y) the aggregate of the Issuer's remaining future funding
obligations in respect of all other Delayed Draw Term Loans then currently owned
by the Issuer, over the Aggregate Class A-1AR Undrawn Amount. The Collateral
Manager shall not permit, at any time, all amounts then on deposit in the
Delayed Funding Obligations Account, together with the Aggregate Class A-1AR
Undrawn Amount, to be less than the aggregate amount of all future funding
obligations outstanding under the terms of all Delayed Draw Term Loans that
constitute Collateral Debt Securities.

          (c) The Collateral Manager shall direct the Trustee to withdraw funds
from the Delayed Funding Obligations Account to fund amounts drawn under any
Delayed Draw Term Loan. Pursuant to an Issuer Order delivered prior to the
Mandatory Class A-1AR Draw Date, all or a portion of the funds, as specified in
such Issuer Order, on deposit in the Delayed Funding Obligations Account at any
time up to an amount equal to the lesser of (x) the amount then on deposit in
the Delayed Funding Obligations Account or (y) the amount by which (A) the sum
of the amount then on deposit in the Delayed Funding Obligations Account plus
the Aggregate Class A-1AR Undrawn Amount exceeds (B) the aggregate principal
amount of commitments which may be drawn upon under the Delayed Draw Term Loans
shall be transferred by the Trustee to the Unused Proceeds Account. Pursuant to
an Issuer Order delivered on or after the Mandatory Class A-1AR Draw Date, all
or a portion of the funds, as specified in such Issuer Order, on deposit in the
Delayed Funding Obligations Account at any time in excess of the aggregate
principal amount of commitments which may be drawn upon under the Delayed Draw
Term Loan shall be transferred by the Trustee to the Collection Account as
Principal Proceeds.

          Section 10.7 Expense Account.

          (a) The Trustee shall prior to the Closing Date establish a single,
segregated trust account which shall be designated as the "Expense Account"
which shall be held in trust in the name of the Trustee for the benefit of the
Secured Parties. The only permitted withdrawal from or application of funds on
deposit in, or otherwise standing to the credit of, the Expense Account shall be
to pay (on any day other than a Payment Date) (i) accrued and unpaid Company
Administrative Expenses (other than accrued and unpaid expenses and indemnities
payable to the Collateral Manager under the Collateral Management Agreement) and
(ii) amounts representing accrued interest in connection with the purchase by
the Issuer during the Ramp Up Period of Collateral Debt Securities. On the
Closing Date, the Trustee shall deposit into the Expense Account an amount equal
to $976,869.50 from the net proceeds received by the Issuer on such date from
the initial issuance of the Securities. On or after the Effective Date, any
amount remaining in the Expense Account may, at the election of the Collateral
Manager be designated as Interest Proceeds. On the date on which substantially
all of the Issuer's assets have been sold or otherwise disposed of, the Issuer
by Issuer Order executed by an Authorized Officer of the Collateral Manager
shall direct the Trustee to, and, upon receipt of such Issuer Order, the Trustee
shall, transfer all amounts on deposit in the Expense Account to the Interest
Collection Account for application pursuant to Section 11.1(a)(i) as Interest
Proceeds. Amounts credited to the


                                      -199-

<PAGE>

Expense Account may be applied on or prior to the Determination Date preceding
the first Payment Date to pay amounts due in connection with the offering of the
Notes.

          (b) The Trustee agrees to give the Issuer immediate notice if it
becomes aware that the Expense Account or any funds on deposit therein, or
otherwise to the credit of the Expense Account, shall become subject to any
writ, order, judgment, warrant of attachment, execution or similar process. The
Issuer shall not have any legal, equitable or beneficial interest in the Expense
Account. The Expense Account shall remain at all times with the Corporate Trust
Office or a financial institution having a long-term debt rating by each Rating
Agency at least equal to "A-" or "Baa1," as applicable.

          (c) The Collateral Manager, on behalf of the Issuer, may direct the
Trustee to, and upon such direction the Trustee shall, invest all funds in the
Expense Account in Eligible Investments designated by the Collateral Manager.
All interest and other income from such investments shall be deposited in the
Expense Account, any gain realized from such investments shall be credited to
the Expense Account, and any loss resulting from such investments shall be
charged to the Expense Account. The Trustee shall not in any way be held liable
(except as a result of negligence, willful misconduct or bad faith) by reason of
any insufficiency of such Expense Account resulting from any loss relating to
any such investment, except with respect to investments in obligations of the
Trustee or any Affiliate thereof. If the Trustee does not receive investment
instructions from an Authorized Officer of the Collateral Manager, the Trustee
shall invest funds received in the Expense Account in Eligible Investments of
the type described in clause (ii) of the definition thereto.

          Section 10.8 Defeased Collateral Accounts.

          (a) The Trustee shall, on or after the Closing Date, at the direction
of the Issuer (or the Collateral Manager on the Issuer's behalf) establish and
maintain one or more segregated trust accounts which will be designated the
"Defeased Collateral Accounts." On each date on which the Issuer receives from
the related borrower in respect of a Loan included in the Assets substitute or
additional collateral in the form of Cash or Eligible Investments in connection
with a defeasance of such Loan, such substitute or additional collateral shall
be transferred by the Issuer (or by the Collateral Manger on behalf of the
Issuer) to the Trustee and the Trustee thereafter shall deposit such substitute
or additional collateral into a Defeased Collateral Account; provided that this
Section 10.8(a) shall not apply to any such substitute or additional collateral
received by the Issuer in connection with the release of any lien on condominium
units to the extent that such additional or substitute collateral is held by the
Servicer in an Eligible Account pending application of such collateral to pay
principal of and/or interest on the related Collateral Debt Security in
accordance with the terms of the applicable Underlying Instruments. Amounts on
deposit in each Defeased Collateral Account shall be transferred by the Trustee
for deposit into the Interest Collection Account, the Principal Collection
Account and/or the Payment Account, in each case as directed by the Issuer (or
by the Collateral Manager on behalf of the Issuer) pursuant to an Issuer Order.
All Monies deposited from time to time in the Defeased Collateral Account
pursuant to this Indenture shall be held by the Trustee as part of the Assets
and shall be applied to the purposes herein provided.


                                      -200-

<PAGE>

          (b) The Trustee agrees to give the Issuer immediate notice if it
becomes aware that a Defeased Collateral Account or any funds on deposit
therein, or otherwise to the credit of a Defeased Collateral Account, shall
become subject to any writ, order, judgment, warrant of attachment, execution or
similar process. The Issuer shall not have any legal, equitable or beneficial
interest in any Defeased Collateral Account. Each Defeased Collateral Account
shall remain at all times with the Corporate Trust Office or a financial
institution having a long-term debt rating from each Rating Agency at least
equal to "A-" or "A2," as applicable, or a short-term debt rating at least equal
to "A-1," "P-1" or "F1," as applicable.

          (c) The Collateral Manager, on behalf of the Issuer, may direct the
Trustee to, and upon such direction the Trustee shall, invest all funds in the
Defeased Collateral Account in Eligible Investments designated by the Collateral
Manager. All interest and other income from such investments shall be deposited
in the Defeased Collateral Account, any gain realized from such investments
shall be credited to the Defeased Collateral Account, and any loss resulting
from such investments shall be charged to the Defeased Collateral Account. The
Trustee shall not in any way be held liable (except as a result of negligence,
willful misconduct or bad faith) by reason of any insufficiency of the Defeased
Collateral Account resulting from any loss relating to any such investment,
except with respect to investments in obligations of the Trustee or any
Affiliate thereof. If the Trustee does not receive investment instructions from
an Authorized Officer of the Collateral Manager, the Trustee shall invest funds
received in the Defeased Collateral Account in Eligible Investments of the type
described in clause (ii) of the definition thereto.

          Section 10.9 Interest Advances.

          (a) With respect to each Determination Date for which the sum of
Interest Proceeds and, if applicable, Principal Proceeds, collected during the
related Due Period that are available to pay interest on the Class A-1 Notes,
the Class A-2 Notes and the Class B Notes in accordance with the Priority of
Payments, are insufficient to remit the interest due and payable with respect to
the Class A-1 Notes, the Class A-2 Notes and the Class B Notes on the following
Payment Date to the extent such shortfall results from interest shortfalls on
the Non-Advancing Collateral Debt Securities (the amount of such insufficiency,
an "Interest Shortfall"), the Trustee shall provide the Advancing Agent with
written notice of such Interest Shortfall no later than the close of business on
the Business Day following such Determination Date. The Trustee shall provide
the Advancing Agent with notice, prior to any funding of an Interest Advance by
the Advancing Agent, of any additional interest remittances received by the
Trustee after delivery of such initial notice that reduce such Interest
Shortfall. No later than 5:00 p.m. (New York time) on the Business Day
immediately preceding the related Payment Date (but in any event no earlier than
one Business Day following the Advancing Agent's receipt of notice of such
Interest Shortfall), the Advancing Agent shall advance the difference between
such amounts (each such advance, an "Interest Advance") by deposit of an amount
equal to such Interest Advance in the Payment Account, subject to a
determination of recoverability by the Advancing Agent as described in Section
10.9(b), and subject to a maximum limit in respect of any Payment Date equal to
the lesser of (i) the aggregate of such Interest Shortfalls that would otherwise
occur on the Class A-1 Notes, the Class A-2 Notes and Class B Notes and (ii) the
aggregate of the interest payments not received in respect of Non-Advancing
Collateral Debt Securities. Notwithstanding the foregoing, in no circumstance
will the Advancing Agent be required to make an Interest


                                      -201-

<PAGE>

Advance in respect of a Non-Advancing Collateral Debt Security (x) to the extent
that the aggregate outstanding amount of all unreimbursed Interest Advances
would exceed the aggregate outstanding principal amount of the Class A Notes and
the Class B Notes or (y) if the Class A/B Par Value Ratio on the relevant
Measurement Date is less than 100%. Any Interest Advance made by the Advancing
Agent with respect to a Payment Date that is in excess of the actual Interest
Shortfall for such Payment Date shall be refunded to the Advancing Agent by the
Trustee on the same Business Day that such Interest Advance was made (or, if
such Interest Advance is made prior to final determination by the Trustee of
such Interest Shortfall, on the Business Day of such final determination). The
Advancing Agent shall provide the Trustee written notice of a determination by
the Advancing Agent that a proposed Interest Advance would constitute a
Nonrecoverable Interest Advance no later than the close of business on the
Business Day immediately preceding the related Payment Date (or, in the event
that the Advancing Agent did not receive notice of the related Interest
Shortfall on the related Determination Date, no later than the close of business
on the Business Day immediately following the Advancing Agent's receipt of
notice of such Interest Shortfall). If the Advancing Agent shall fail to make
any required Interest Advance at or prior to the time at which distributions are
to be made pursuant to Section 11.1(a), the Backup Advancing Agent shall be
required to make such Interest Advance, subject to a determination of
recoverability by the Backup Advancing Agent as described in Section 10.9(b).
The Backup Advancing Agent shall be entitled to conclusively rely on any
affirmative determination by the Advancing Agent that an Interest Advance would
constitute a Nonrecoverable Interest Advance. Based upon available information
at the time, the Backup Advancing Agent, the Collateral Manager or the Advancing
Agent will provide 15 days prior notice to each Rating Agency if recovery of a
Nonrecoverable Interest Advance would result in an Interest Shortfall on the
next succeeding Payment Date. No later than the close of business on the
Determination Date related to a Payment Date on which the recovery of a
Nonrecoverable Interest Advance would result in an Interest Shortfall, the
Collateral Manager will provide each Rating Agency notice of such recovery.

          (b) Notwithstanding anything herein to the contrary, neither the
Advancing Agent nor the Backup Advancing Agent, as applicable, shall be required
to make any Interest Advance unless such Person determines, in its sole
discretion, exercised in good faith that such Interest Advance, or such proposed
Interest Advance, plus interest expected to accrue thereon at the Reimbursement
Rate, will be recoverable from subsequent payments or collections with respect
to all Collateral Debt Securities and has determined in its reasonable judgment
that the recovery would not result in an Interest Shortfall. In determining
whether any proposed Interest Advance will be, or whether any Interest Advance
previously made is, a Nonrecoverable Interest Advance, the Advancing Agent or
the Backup Advancing Agent, as applicable, will take into account:

          (i) amounts that may be realized on each Underlying Mortgage Property
     in its "as is" or then-current condition and occupancy;

          (ii) that the related Senior Tranches of any Collateral Debt Security
     may be required to be fully paid and any advances (and interest thereon)
     made in respect of such Senior Tranches may be required to be fully
     reimbursed, prior to any amounts recovered in respect of the Underlying
     Mortgage Properties are allocated or otherwise made available to the
     Collateral Debt Securities;


                                      -202-

<PAGE>

          (iii) the possibility and effects of future adverse change with
     respect to the Underlying Mortgage Properties, the potential length of time
     before such Interest Advance may be reimbursed and the resulting degree of
     uncertainty with respect to such reimbursement; and

          (iv) the fact that Interest Advances are intended to provide liquidity
     only and not credit support to the Holders of the Class A-1 Notes, the
     Class A-2 Notes and the Class B Notes.

          For purposes of any such determination of whether an Interest Advance
constitutes or would constitute a Nonrecoverable Interest Advance, an Interest
Advance will be deemed to be nonrecoverable if the Advancing Agent or the Backup
Advancing Agent, as applicable, determines that future Interest Proceeds and
Principal Proceeds may be ultimately insufficient to fully reimburse such
Interest Advance, plus interest thereon at the Reimbursement Rate within a
reasonable period of time. Absent bad faith, the determination by the Advancing
Agent or the Backup Advancing Agent, as applicable, as to the nonrecoverability
of any Interest Advance shall be conclusive and binding on the Holders of the
Notes.

          (c) Each of the Advancing Agent and the Backup Advancing Agent will
each be entitled to recover any previously unreimbursed Interest Advance made by
it (including any Nonrecoverable Interest Advance), together with interest
thereon, first, from Interest Proceeds and second (to the extent that there are
insufficient Interest Proceeds for such reimbursement), from Principal Proceeds
to the extent that such reimbursement would not trigger an additional Interest
Shortfall; provided that if at any time an Interest Advance is determined to be
a Nonrecoverable Interest Advance, the Advancing Agent or the Backup Advancing
Agent shall be entitled to recover all outstanding Interest Advances from the
Collection Accounts on any Business Day during any Interest Accrual Period prior
to the related Determination Date (or on a Payment Date prior to any payment of
interest on or principal of the Notes in accordance with the Priority of
Payments). The Advancing Agent shall be permitted (but not obligated) to defer
or otherwise structure the timing of recoveries of Nonrecoverable Interest
Advances in such manner as the Advancing Agent determines is in the best
interest of the Class A Notes and the Class B Notes, as a collective whole,
which may include being reimbursed for Nonrecoverable Interest Advances in
installments.

          (d) The Advancing Agent and the Backup Advancing Agent will each be
entitled with respect to any Interest Advance made by it (including
Nonrecoverable Interest Advances) to interest accrued on the amount of such
Interest Advance for so long as it is outstanding at the Reimbursement Rate.

          (e) The obligations of the Advancing Agent and the Backup Advancing
Agent to make Interest Advances in respect of the Collateral Debt Securities
will continue through the Stated Maturity, unless the Class A Notes and the
Class B Notes are previously redeemed or repaid in full.

          (f) In no event will the Advancing Agent in its capacity as such
hereunder or the Trustee, in its capacity as Backup Advancing Agent hereunder,
be required to make Interest Advances for distributions to the Holders of any
Class of Notes other than the Class A-1 Notes,


                                      -203-

<PAGE>

the Class A-2 Notes and the Class B Notes or with respect to any Collateral Debt
Security other than a Non-Advancing Collateral Debt Security, and in no event
will the Advancing Agent or the Backup Advancing Agent be required to advance
any amounts in respect of payments of Principal of any Collateral Debt Security.

          (g) In consideration of the performance of its obligations hereunder,
the Advancing Agent shall be entitled to receive, at the times set forth herein
and subject to the Priority of Payments, to the extent funds are available
therefor, the Advancing Agent Fee. In consideration of the Backup Advancing
Agent's obligations hereunder, the Backup Advancing Agent shall be entitled to
receive, at the times set forth herein and subject to the Priority of Payments,
to the extent funds are available therefor, the Backup Advancing Agent Fee. If
the Backup Advancing Agent makes an Interest Advance that the Advancing Agent
failed to make and did not determine to be nonrecoverable, the Backup Advancing
Agent will be entitled to receive the Advancing Agent's Fee for so long as such
Interest Advance is outstanding.

          (h) The determination by the Advancing Agent or the Backup Advancing
Agent, as applicable, (i) that it has made a Nonrecoverable Interest Advance or
(ii) that any proposed Interest Advance, if made, would constitute a
Nonrecoverable Interest Advance, shall be evidenced by an Officer's Certificate
delivered promptly to the Trustee (or, if applicable, retained thereby), the
Issuer, S&P, Fitch and Moody's, setting forth the basis for such determination;
provided that failure to give such notice, or any defect therein, shall not
impair or affect the validity of, or the Advancing Agent or the Backup Advancing
Agent, entitlement to reimbursement with respect to, any Interest Advance.

          (i) If a Scheduled Distribution on any Collateral Debt Security is not
paid to the Trustee on the Due Date therefor, the Trustee shall provide the
Advancing Agent with notice of such default on the Business Day immediately
following such default. In addition, upon request, the Trustee shall provide the
Advancing Agent (either electronically or in hard-copy format), with copies of
all reports received from any trustee, trust administrator, master servicer or
similar administrative entity with respect to the Collateral Debt Securities and
the Trustee shall promptly make available to the Advancing Agent any other
information reasonably available to the Trustee by reason of its acting as
Trustee hereunder to permit the Advancing Agent to make a determination of
recoverability with respect to any Interest Advance and to otherwise perform its
advancing functions under this Indenture.

          Section 10.10 Reports by Parties.

          (a) The Trustee shall supply, in a timely fashion, to the Issuer, the
Co-Issuer, the Preferred Shares Paying Agent and the Collateral Manager any
information regularly maintained by the Trustee that the Issuer, the Co-Issuer,
the Preferred Shares Paying Agent or the Collateral Manager may from time to
time request with respect to the Pledged Obligations or the Accounts and provide
any other information reasonably available to the Trustee by reason of its
acting as Trustee hereunder and required to be provided by Section 10.11 or to
permit the Collateral Manager to perform its obligations under the Collateral
Management Agreement. The Trustee shall forward to the Collateral Manager and
each Hedge Counterparty copies of notices and other writings received by it from
the issuer of any Collateral Debt Security or from any Clearing Agency with
respect to any Collateral Debt Security advising the holders of such


                                      -204-

<PAGE>

security of any rights that the holders might have with respect thereto
(including, without limitation, notices of calls and redemptions of securities)
as well as all periodic financial reports received from such issuer and Clearing
Agencies with respect to such issuer. Each of the Issuer and Collateral Manager
shall promptly forward to the Trustee any information in their possession or
reasonably available to them concerning any of the Pledged Obligations that the
Trustee reasonably may request or that reasonably may be necessary to enable the
Trustee to prepare any report or perform any duty or function on its part to be
performed under the terms of this Indenture.

          Section 10.11 Reports; Accountings.

          (a) The Trustee shall monitor the Assets on an ongoing basis and

in accordance with this Indenture.

          (b) The Trustee shall perform the following functions during the term
of this Indenture:

          (i) create and maintain a database with respect to the Collateral Debt
     Securities (the "Database");

          (ii) permit access to the information contained in the Database by the
     Collateral Manager and the Issuer;

          (iii) on a monthly basis monitor and update the Database for ratings
     changes;

          (iv) update the Database for Collateral Debt Securities or Eligible
     Investments acquired or sold or otherwise disposed of;

          (v) prepare and arrange for the delivery to each Rating Agency, the

     request therefor, any Holder of a Note shown on the Note Registrar, any
     Preferred Shareholder shown on the register maintained by the Share

     are listed on the Irish Stock Exchange, the Irish Paying Agent of the
     Monthly Reports;

          (vi) prepare and arrange for the delivery to the Collateral Manager,

called for in the order and according to the priority set forth under Section
11.1(a) above, subject to Section 13.1 hereof, to the extent funds are available
therefor.

          (d) Except as otherwise expressly provided in this Section 11.1, if on
any Payment Date the amount available in the Payment Account from amounts

clause ratably in accordance with the respective amounts of such disbursements
then due and payable to the extent funds are available therefor, unless such
clause provides otherwise.

          (e) [Reserved].

                       SALE OF COLLATERAL DEBT SECURITIES

          Section 12.1 Sales of Collateral Debt Securities.

          (a) Except as otherwise expressly permitted or required by this
Indenture, the Issuer shall not sell or otherwise dispose of any Collateral Debt
Security; provided that, subject to satisfaction of any applicable conditions in
Section 10.12, so long as (A) no Event of Default has occurred and is continuing
and (B) on or prior to the trade date for such sale the Collateral Manager has
certified to the Trustee that each of the conditions applicable to such sale set
forth below has been satisfied, the Collateral Manager, on behalf of the Issuer,
acting pursuant to the Collateral Management Agreement may direct the Trustee in
writing to sell, and the Trustee shall sell in the manner directed by the
Collateral Manager in writing (which writing shall specify whether such security
is a Defaulted Security, Credit Risk Security or a Buy/Sell Interest, if
applicable, or whether such security is otherwise permitted to be sold pursuant
to this Section 12.1(a)):

          (i) any Defaulted Security at any time; provided that, if such Sale
     Proceeds are reinvested, the Collateral Manager will use commercially
     reasonable efforts to purchase one or more Substitute Collateral Debt
     Securities having an aggregate Principal Balance (including for this
     purpose accrued interest) no less than such Sale Proceeds (excluding
     accrued interest);

          (ii) a Credit Risk Security, (a) during the Reinvestment Period, if
     the Collateral Manager has certified to the Trustee that it shall use
     commercially reasonable efforts to purchase one or more Substitute
     Collateral Debt Securities having an Aggregate Principal Balance (including
     for this purpose accrued interest) no less than the Sale Proceeds
     (excluding accrued interest) from such sale, and after giving effect to
     such sale


                                      -231-

<PAGE>

     and to the purchase of Substitute Collateral Debt Securities with the Sale
     Proceeds thereof, in the judgment of the Collateral Manager (which shall
     not be called into question solely as a result of subsequent events), the
     Reinvestment Criteria shall be satisfied and (b) after the Reinvestment
     Period, at any time;

          (iii) if a Collateral Debt Security that is a Defaulted Security is
     not sold by the Issuer (at the direction of the Collateral Manager) within
     three years of such Collateral Debt Security becoming a Defaulted Security,
     the Collateral Manager, on behalf of the Issuer, shall use its commercially
     reasonable efforts to sell such Collateral Debt Security as soon as
     commercially practicable thereafter;

          (iv) any Buy/Sell Interest at any time; provided that if Sale Proceeds
     in respect of any Buy/Sell Interest are reinvested, the Collateral Manager
     will use commercially reasonable efforts to purchase one or more Substitute
     Collateral Debt Securities having an aggregate Principal Balance (including
     for this purpose accrued interest) no less than such Sale Proceeds
     (excluding accrued interest); and

          (v) without limiting the foregoing, any Collateral Debt Security that
     is not a Defaulted Security or a Credit Risk Security may be sold during
     the Reinvestment Period, if (a) the Aggregate Principal Balance of
     Collateral Debt Securities sold pursuant to this paragraph for a given
     calendar year does not exceed 10% of the Aggregate Collateral Balance as of
     the beginning of that year, (b) the Collateral Manager believes in good
     faith that proceeds from the sale of such Collateral Debt Security can be
     reinvested, within five Business Days after the trade date on which such
     Collateral Debt Security is sold in one or more Substitute Collateral Debt
     Securities having an Aggregate Principal Balance (including for this
     purpose accrued interest) of not less than 100% of the Principal Balance of
     the Collateral Debt Security being sold, (c) after giving effect to such
     sale and to the purchase of Substitute Collateral Debt Securities with the
     Sale Proceeds thereof, the Reinvestment Criteria will be satisfied and (d)
     so long as MBIA is deemed to be the Controlling Class, unless MBIA
     otherwise consents, ARCM has not been removed, or voted to be removed, as
     Collateral Manager under the Collateral Management Agreement. For the
     avoidance of doubt, any sales of Collateral Debt Securities made pursuant
     to Section 12.2(c) or (d) shall be disregarded in determining compliance
     with this Section 12.1(a)(v).

          (b) Notwithstanding the foregoing, the Collateral Manager (at its
option and at any time) shall be permitted to effect a sale of a Credit Risk
Security or a Defaulted Security hereunder by purchasing (or causing its
Affiliate to purchase) such Defaulted Security or Credit Risk Security from the
Issuer for a Cash purchase price that shall be equal to the sum of (i) the
Aggregate Principal Balance thereof plus (ii) all accrued and unpaid interest
(or, in the case of a Preferred Equity Security, all accrued and unpaid
dividends or other distributions not attributable to the return of capital by
the related Underlying Instruments) thereon. Notwithstanding anything to the
contrary set forth herein, no Advisory Committee consent shall be required in
connection with such Cash purchase (the "Credit Risk/Defaulted Security Cash
Purchase").

          In addition and notwithstanding anything to the contrary set forth
herein (and provided no Event of Default has occurred and is continuing), the
Collateral Manager (at its


                                      232-

<PAGE>

option but only upon disclosure to, and with the prior consent of, the Advisory
Committee) shall be permitted to effect a sale of a Defaulted Security or a
Credit Risk Security hereunder by directing the Issuer to exchange such
Defaulted Security or Credit Risk Security for (i) a Substitute Collateral Debt
Security (that is not a Defaulted Security or a Credit Risk Security) owned by
an Affiliate of the Collateral Manager (such Substitute Collateral Debt
Security, the "Exchange Security") or (ii) a combination of an Exchange Security
and Cash; provided that:

          (i) (A) the sum of (1) the Principal Balance of such Exchange Security
     plus (2) all accrued and unpaid interest (or, in the case of a Preferred
     Equity Security, all accrued and unpaid dividends or other distributions
     not attributable to the return of capital by its governing documents)
     thereon plus (3) the Cash amount (if any) to be paid to the Issuer in
     respect of such exchange by such Affiliate of the Collateral Manager, shall
     be equal to or greater than (B) the sum of (1) the Principal Balance of
     such Defaulted Security or Credit Risk Security sought to be substituted
     plus (2) all accrued and unpaid interest (or, in the case of a Preferred
     Equity Security, all accrued and unpaid dividends or other distributions
     not attributable to the return of capital by its governing documents)
     thereon;

          (ii) the Eligibility Criteria and the Reinvestment Criteria shall be
     satisfied immediately after such exchange; and

          (iii) the Aggregate Principal Balance of all such Defaulted Securities
     and Credit Risk Securities so exchanged shall not exceed 10% of the
     Aggregate Collateral Balance as of the Closing Date (such limitation, the
     "10% Limit").

          (c) After the Issuer has notified the Trustee of an Optional
Redemption, a Clean-Up Call or a Tax Redemption in accordance with Section 9.1
or an Auction Call Redemption in accordance with Section 9.2, the Collateral
Manager, on behalf of the Issuer, and acting pursuant to the Collateral
Management Agreement, may at any time direct the Trustee in writing to sell, and
the Trustee shall sell in the manner directed by the Collateral Manager in
writing, any Collateral Debt Security without regard to the foregoing
limitations in Section 12.1(a); provided that:

          (i) the Sale Proceeds therefrom must be used to pay certain expenses
     and redeem all of the Notes in whole but not in part pursuant to Section
     9.1 and Section 9.2, and upon any such sale the Trustee shall release such
     Collateral Debt Security pursuant to Section 10.12;

          (ii) the Issuer may not direct the Trustee to sell (and the Trustee
     shall not be required to release) a Collateral Debt Security pursuant to
     this Section 12.1(c) unless:

               (1) the Collateral Manager certifies to the Trustee that (x) in
          the Collateral Manager's reasonable business judgment based on
          calculations included in the certification (which shall include the
          sales prices of the Collateral Debt Securities), the Sale Proceeds
          from the sale of one or more of the Collateral Debt Securities and all
          Cash and proceeds from Eligible Investments will be at least equal to
          the Total Redemption Price, and (y) an Independent bond pricing

          confirmation); and

               (2) the Independent accountants appointed by the Issuer pursuant
          to Section 10.13 shall confirm in writing the calculations made in
          clause (1)(x) above.

          (iii) in connection with an Optional Redemption, an Auction Call
     Redemption, a Clean-up Call or a Tax Redemption, all the Collateral Debt
     Securities to be sold pursuant to this Section 12.1(c) must be sold in
     accordance with the requirements set forth in Section 9.1(e) and Section
     9.2, as applicable.

          (d) In the event that any Collateral Debt Security becomes the subject
of a conversion, exchange, redemption or offer, whether voluntary or
involuntary, the Issuer (or the Collateral Manager on behalf of the Issuer)
shall take no action to acquire the asset or instrument into which such
Collateral Debt Security is convertible or exchangeable unless such asset or
instrument would qualify as a Substitute Collateral Debt Security. In the event
of an involuntary exchange or conversion of a Collateral Debt Security, if the
resulting asset or instrument would not qualify as a Substitute Collateral Debt
Security, the Issuer (or the Collateral Manager on behalf of the Issuer) shall
use commercially reasonable efforts to sell such Collateral Debt Security prior
to conversion or exchange and, in any event, shall refuse to accept, and shall
not acquire or hold, the asset or instrument offered in exchange.

          (e) In the event that any Notes remain Outstanding as of the Payment
Date occurring six months prior to the Stated Maturity of the Notes, the
Collateral Manager will be required to determine whether the proceeds expected
to be received on the Assets prior to the Stated Maturity of the Notes will be
sufficient to pay in full the principal amount of (and accrued interest on) the
Notes on the Stated Maturity. If the Collateral Manager determines, in its sole
discretion, that such proceeds will not be sufficient to pay the outstanding
principal amount of and accrued interest on the Notes (a "Note Liquidation
Event") on the Stated Maturity of the Notes, the Issuer will, at the direction
of the Collateral Manager, be obligated to liquidate the portion of Collateral
Debt Securities sufficient to pay the remaining principal amount of and interest
on the Notes on or before the Stated Maturity. The Collateral Debt Securities to
be liquidated by the Issuer will be selected by the Collateral Manager.

          (f) Notwithstanding anything herein to the contrary, in the event that
a "buy/sell" arrangement has been initiated with respect to a Collateral Debt
Security as a dispute resolution mechanism and the Collateral Manager determines
in accordance with the Collateral Manager Servicing Standard that the sale of
such Collateral Debt Security is in the best interest of the Noteholders, the
Collateral Manager may, on behalf of the Issuer, direct the Trustee to sell such
Collateral Debt Security in accordance with the related Underlying Instruments;
provided that, in the event any such sale is to be made to an Affiliate of the
Issuer or the Collateral


                                      -234-

<PAGE>

Manager, such sale may be made only upon disclosure to, and with the prior
consent of, the Advisory Committee.

          (g) Notwithstanding anything contained in this Section 12.1 to the
contrary, the Issuer may sell any Collateral Debt Security in accordance with
the provisions of Sections 12.2(c), 12.2(d) and/or 12.2(f).

          Section 12.2 Reinvestment Criteria and Trading Restrictions.

          (a) Except as provided in Section 12.3(c), during the Reinvestment
Period, Unscheduled Principal Payments, Sale Proceeds and other Principal
Proceeds (including excess amounts on deposit in the Delayed Funding Obligations
Account and certain Class A-1AR Draws) will be reinvested in Substitute
Collateral Debt Securities (which shall be, and hereby are, Granted to the
Trustee pursuant to the Granting Clause of this Indenture) only if the
Collateral Manager has not been removed, or voted to be removed, as a Collateral
Manager under the Collateral Management Agreement or a substitute collateral
manager has been appointed and, after giving effect to such reinvestment, the
following criteria (which criteria shall also apply with respect to investments
in Collateral Debt Securities during the Ramp-Up Period) (the "Reinvestment
Criteria") are satisfied, as evidenced by an Officer's Certificate of the Issuer
or the Collateral Manager delivered to the Trustee, as of the date of the
commitment to purchase such Substitute Collateral Debt Securities:

          (i) such security satisfies the Eligibility Criteria;

          (ii) the Collateral Quality Tests are satisfied, or, if any Collateral
     Quality Test was not satisfied immediately prior to such reinvestment, the
     extent of compliance with such Collateral Quality Test will be maintained
     or improved following such reinvestment, except as otherwise specified in
     the Reinvestment Criteria below;

          (iii) the Coverage Tests are satisfied (or, if not satisfied, are
     maintained or improved); provided that, if the Class A/B
     Overcollateralization Test is not satisfied, the Issuer will not effect
     such reinvestment if sufficient proceeds would not remain on deposit in the
     Collection Accounts following such reinvestment to cause the Class A/B
     Overcollateralization Test to be satisfied following disbursements on the
     following Payment Date in accordance with the Priority of Payments;

          (iv) if immediately prior to such reinvestment the S&P CDO Monitor
     Test or the S&P Recovery Test was not satisfied, such test result is
     maintained or improved after giving effect to such reinvestment; provided,
     however, that notwithstanding the foregoing, Sale Proceeds of Credit Risk
     Securities may be reinvested as long as the Collateral Manager provides
     written notice of each such sale and reinvestment to S&P within three
     Business Days after such reinvestment; and

          (v) no Event of Default has occurred and is continuing.

          (b) Subject to the conditions set forth in Sections 12.2(c) and
12.2(d), during the Ramp-Up Period and the Reinvestment Period the Issuer may
acquire Loans based on an Estimated Rating; provided, however, that after the
Effective Date the Issuer may not acquire a


                                      -235-

<PAGE>

Collateral Debt Security based on an Estimated Rating if (a) such acquisition
would cause the aggregate Principal Balance of all Collateral Debt Securities
owned by the Issuer which do not yet have an S&P Assigned Rating to exceed 20%
of the Aggregate Collateral Balance as of the Closing Date, (b) such acquisition
would cause the Aggregate Principal Balance of all Collateral Debt Securities
owned by the Issuer which do not yet have a Moody's Assigned Rating to exceed
20% of the Aggregate Collateral Balance as of the Closing Date, (c) solely with
respect to Collateral Debt Securities that are collateralized or backed by
interests on a Property Type other than a Non-Core Property Type related to a
single obligor, such acquisition would cause the Aggregate Principal Balance of
all such Collateral Debt Securities owned by the Issuer which do not yet have a
Moody's Assigned Rating to exceed 5% of the Aggregate Collateral Balance as of
the Closing Date, or (d) solely with respect to Collateral Debt Securities that
are collateralized or backed by interests on a Non-Core Property Type related to
a single obligor, such acquisition would cause the Aggregate Principal Balance
of all such Collateral Debt Securities owned by the Issuer which do not yet have
a Moody's Assigned Rating to exceed 3.5% of the Aggregate Collateral Balance as
of the Closing Date. In addition, no Future Advance Loan with respect to which
the related Unfunded Other Loan is a Construction Loan may be purchased by the
Issuer based on a Moody's Estimated Rating.

          (c) Within ten Business Days after acquiring a Collateral Debt
Security based on a Moody's Estimated Rating, the Collateral Manager shall
deliver to Moody's a comprehensive set of asset and underwriting materials
describing such Collateral Debt Security, in form and substance acceptable to
Moody's. With respect to each Substitute Collateral Debt Security acquired based
on a Moody's Estimated Rating after the Effective Date, the Collateral Manager
shall determine compliance with the Moody's Post-Acquisition Compliance Test
when it receives notice from Moody's of the Moody's Assigned Rating for such
Substitute Collateral Debt Security. Within 45 days after finding that the
acquisition of a Substitute Collateral Debt Security after the Effective Date
resulted in a failure to satisfy the Moody's Post-Acquisition Compliance Test (a
"Moody's Post-Acquisition Failure"), the Collateral Manager shall use
commercially reasonable efforts to remedy such Moody's Post-Acquisition Failure
by either: (a) causing the Issuer and instructing the Trustee to sell to the
Collateral Manager or its Affiliates or to a third party the Substitute
Collateral Debt Security that caused the Moody's Post-Acquisition Failure, for a
cash price that is greater than or equal to the sum of (i) the then outstanding
Principal Balance of such Substitute Collateral Debt Security, discounted based
on the percentage amount of any discount that was applied when such Substitute
Collateral Debt Security was purchased by the Issuer (or, if such asset was
purchased by the Issuer at a premium, then the outstanding Principal Balance
shall be subject to a percentage premium not less than that at which the Issuer
purchased such asset), plus (ii) any accrued but unpaid interest on such
Substitute Collateral Debt Security plus (iii) any fees and expenses of the
Issuer attributable to such sale, or (b) causing the Issuer and instructing the
Trustee to sell other Collateral Debt Securities (in the case of each such
Collateral Debt Security, for a cash price that is greater than or equal to the
sum of (i) the then outstanding Principal Balance of such Collateral Debt
Security, discounted based on the percentage amount of any discount that was
applied when such Collateral Debt Security was purchased by the Issuer (or, if
such asset was purchased by the Issuer at a premium, then the outstanding
Principal Balance shall be subject to a percentage premium not less than that at
which the Issuer purchased such asset), plus (ii) any accrued but unpaid
interest on such Collateral Debt Security) and/or purchase other Collateral Debt
Securities (subject to the Reinvestment Criteria) so that either (x) the Moody's
Maximum


                                      -236-

<PAGE>

Tranched Rating Factor Test is satisfied, or (y) if the Moody's Maximum Tranched
Rating Factor Test was not satisfied immediately prior to the purchase of the
Substitute Collateral Debt Security that resulted in the Moody's
Post-Acquisition Failure, the level of compliance with the Moody's Maximum
Tranched Rating Factor Test is restored to the level that would exist if that
Substitute Collateral Debt Security had not been purchased. Following a Moody's
Post-Acquisition Failure, until such time as the Moody's Post-Acquisition
Failure has been remedied as provided above, the Issuer may only purchase
Substitute Collateral Debt Securities that have a Moody's Assigned Rating;
provided, however, that if the Moody's Post-Acquisition Failure has not been
remedied within 45 days after a finding of such Moody's Post-Acquisition
Failure, then each Substitute Collateral Debt Security thereafter acquired by
the Issuer must have a Moody's Assigned Rating until such time as the Rating
Agency Condition with respect to Moody's has been satisfied and, so long as MBIA
is deemed to be the Controlling Class hereunder, MBIA has consented; provided,
further, that if the Moody's Post-Acquisition Failure has not been remedied
within 120 days after a finding of such Moody's Post-Acquisition Failure, then
the Issuer may no longer acquire Substitute Collateral Debt Securities based on
a Moody's Estimated Rating, even if such Moody's Post-Acquisition Failure is
later remedied.

          (d) Within ten Business Days after acquiring a Collateral Debt
Security based on an S&P Estimated Rating, the Collateral Manager shall deliver
to S&P a comprehensive set of asset and underwriting materials describing such
Collateral Debt Security, in form and substance acceptable to S&P. With respect
to each Substitute Collateral Debt Security acquired based on an S&P Estimated
Rating after the Effective Date, the Collateral Manager shall determine
compliance with the S&P Post-Acquisition Compliance Test when it receives notice
from S&P of the S&P Assigned Rating for such Substitute Collateral Debt
Security. Within 45 days after finding that the acquisition of a Substitute
Collateral Debt Security after the Effective Date resulted in a failure to
satisfy the S&P's Post-Acquisition Compliance Test (an "S&P Post-Acquisition
Failure"), the Collateral Manager may remedy such S&P Post-Acquisition Failure
by either: (a) causing the Issuer and instructing the Trustee to sell to the
Collateral Manager or its Affiliates or to a third party the Substitute
Collateral Debt Security that caused the S&P Post-Acquisition Failure, for a
cash price that is greater than or equal to the sum of (i) the then outstanding
Principal Balance of such Substitute Collateral Debt Security, discounted based
on the percentage amount of any discount that was applied when such Substitute
Collateral Debt Security was purchased by the Issuer (or, if such asset was
purchased by the Issuer at a premium, then the outstanding Principal Balance
shall be subject to a percentage premium not less than that at which the Issuer
purchased such asset), plus (ii) any accrued but unpaid interest on such
Substitute Collateral Debt Security, plus (iii) any fees and expenses of the
Issuer attributable to such sale, or (b) causing the Issuer and instructing the
Trustee to sell other Collateral Debt Securities and/or purchase other
Substitute Collateral Debt Securities (subject to the Reinvestment Criteria) so
that either (x) the S&P CDO Monitor Test is satisfied, or (y) if the S&P CDO
Monitor Test was not satisfied immediately prior to the purchase of the
Substitute Collateral Debt Security that resulted in the S&P Post-Acquisition
Failure, the level of compliance with the S&P CDO Monitor Test is restored to
the level that would exist if that Substitute Collateral Debt Security had not
been purchased. Following an S&P Post-Acquisition Failure, until such time as
the S&P Post-Acquisition Failure has been remedied as provided above, the Issuer
may only purchase Substitute Collateral Debt Securities that have an S&P
Assigned Rating.


                                      -237-
<PAGE>

          (e) No Advisory Committee consent will be required in connection with
a sale or transfer of a Substitute Collateral Debt Security in connection with
any action taken by the Collateral Manager to remedy a Moody's Post-Acquisition
Failure or an S&P Post-Acquisition Failure, even if the Collateral Manager or
its Affiliate is the purchaser or assignee of such asset, so long as the
purchase price for such Collateral Debt Security is payable in cash and is
greater than or equal to the sum of (i) the then outstanding Principal Balance
of such Collateral Debt Security, discounted based on the percentage amount of
any discount that was applied when such Collateral Debt Security was purchased
by the Issuer (or, if such asset was purchased by the Issuer at a premium, then
the outstanding Principal Balance shall be subject to a percentage premium not
less than that at which the Issuer purchased such asset), plus (ii) any accrued
but unpaid interest on such Collateral Debt Security plus (iii) any fees and
expenses of the Issuer attributable to such sale.

          (f) Within ten Business Days after the applicable Rating Agency
notifies the Collateral Manager of the Assigned Rating determined for a
Collateral Debt Security acquired by the Issuer based on an Estimated Rating, if
such Assigned Rating is lower than such Estimated Rating (but, for the avoidance
of doubt, such Assigned Rating is not low enough to cause a Moody's
Post-Acquisition Failure or an S&P Post-Acquisition Failure, as applicable), the
Collateral Manager shall have the option, but not the obligation, to cause the
Issuer and direct the Trustee (x) to sell such Collateral Debt Security to the
Collateral Manager or any of its Affiliates or any third party for a cash price
that is greater than or equal to the sum of (i) the then outstanding Principal
Balance of such Collateral Debt Security, discounted based on the percentage
amount of any discount that was applied when such Collateral Debt Security was
purchased by the Issuer (or, if such asset was purchased by the Issuer at a
premium, then the outstanding Principal Balance shall be subject to a percentage
premium not less than that at which the Issuer purchased such asset), plus (ii)
any accrued but unpaid interest on such Collateral Debt Security plus (iii) any
fees and expenses of the Issuer attributable to such sale. No Advisory Committee
consent will be required in connection with a trade executed in connection with
the exercise of this option even if the Collateral Manager or its Affiliate is
the purchaser or assignee.

          (g) Notwithstanding the foregoing provisions, (i) Cash on deposit in
the Collection Accounts may be invested in Eligible Investments, pending
investment in Substitute Collateral Debt Securities and (ii) if an Event of
Default shall have occurred and be continuing, no Substitute Collateral Debt
Security may be acquired unless it was the subject of a commitment entered into
by the Issuer prior to the occurrence of such Event of Default.

          Section 12.3 Conditions Applicable to all Transactions Involving Sale
or Grant.

          (a) Any transaction effected after the Closing Date under this Article
12 or Section 10.12 shall be conducted in accordance with the requirements of
the Collateral Management Agreement; provided that (1) the Collateral Manager
shall not direct the Trustee to acquire any Substitute Collateral Debt Security
for inclusion in the Assets from the Collateral Manager or any of its Affiliates
as principal or to sell any Collateral Debt Security from the Assets to the
Collateral Manager or any of its Affiliates as principal unless the transaction
is effected in accordance with the Collateral Management Agreement and (2) the
Collateral Manager shall not direct the Trustee to acquire any Substitute
Collateral Debt Security for


                                     -238-

<PAGE>

inclusion in the Assets from any account or portfolio for which the Collateral
Manager serves as investment adviser or direct the Trustee to sell any
Collateral Debt Security to any account or portfolio for which the Collateral
Manager serves as investment adviser unless such transactions comply with the
requirements of any applicable laws. The Trustee shall have no responsibility to
oversee compliance with this clause by the other parties.

          (b) Upon any Grant pursuant to this Article 12, all of the Issuer's
right, title and interest to the Pledged Obligation or Securities shall be
Granted to the Trustee pursuant to this Indenture, such Pledged Obligation or
Securities shall be registered in the name of the Trustee, and, if applicable,
the Trustee shall receive such Pledged Collateral Debt Security or Securities.
The Trustee also shall receive, not later than the date of delivery of any
Collateral Debt Security delivered after the Closing Date, an Officer's
Certificate of the Collateral Manager certifying that, as of the date of such
Grant, such Grant complies with the applicable conditions of and is permitted by
this Article 12 (and setting forth, to the extent appropriate, calculations in
reasonable detail necessary to determine such compliance).

          (c) Notwithstanding anything contained in this Article 12 to the
contrary, the Issuer shall, subject to this Section 12.3(c), have the right to
effect any transaction which has been consented to (i) by the Holders of Notes
evidencing 100% of the Aggregate Outstanding Amount of each and every Class of
Notes (or if there are no Notes Outstanding, 100% of the Preferred Shares) and
(ii) each Hedge Counterparty, and of which each Rating Agency has been notified.

          Section 12.4 Sale of Collateral Debt Securities with respect to an
Auction Call Redemption.

          (a) Pre-Auction Process.

          (i) Each Auction will occur on the Business Day that is at least 13
     Business Days prior to the proposed Auction Call Redemption Date (such
     date, the "Auction Date").

          (ii) The Collateral Manager will initiate the Auction Procedures at
     least 24 Business Days before the proposed Auction Call Redemption Date by:
     (a) preparing a list of Collateral Debt Securities (including CUSIP Number,
     if any, par amount and issuer name for each Collateral Debt Security); (b)
     deriving a list of not less than three qualified bidders (the "Listed
     Bidders") and requesting from each Listed Bidder bids by the applicable
     Auction Date; and (c) notifying the Trustee of the list of Listed Bidders
     (the "List").

          (iii) The Collateral Manager will deliver a general solicitation
     package to the Listed Bidders consisting of: (a) a form of a purchase
     agreement ("Auction Purchase Agreement") provided to the Trustee by the
     Collateral Manager (which shall provide that (I) upon satisfaction of all
     conditions precedent therein, the purchaser is irrevocably obligated to
     purchase, and the Issuer is irrevocably obligated to sell, the Collateral
     Debt Securities on the date and on the terms stated therein, (II) each
     bidder may tender a separate bid for one or more Collateral Debt Securities
     in an Auction, (III) if the


                                     -239-

<PAGE>

     Collateral Debt Securities are to be sold to different bidders, that the
     consummation of the purchase of all Collateral Debt Securities must occur
     simultaneously and that the closing of each purchase is conditional on the
     closing of the other purchases, (IV) if for any reason whatsoever the
     Trustee has not received, by a specified Business Day (which shall be more
     than ten Business Days before the proposed Auction Call Redemption Date),
     payment in full in immediately available funds of the purchase price for
     all Collateral Debt Securities, the obligations of the parties shall
     terminate and the Issuer shall have no obligation or liability whatsoever
     and (V) any prospective purchasers will be subject to the "limited
     recourse" and "non-petition" provisions set forth in this Indenture); (b)
     the minimum aggregate Cash purchase price (which shall be determined by the
     Collateral Manager as the Total Redemption Price less the balance of all
     Eligible Investments and Cash in the Collection Accounts, the Payment
     Account, the Delayed Funding Obligations Account, each Hedge Termination
     Account and the Expense Account); (c) the list of Collateral Debt
     Securities; (d) a formal bid sheet (which will permit a bidder to bid for
     all of the Collateral Debt Securities or separately for any one or more
     (but not all) Collateral Debt Securities and will include a representation
     from the bidder that it is eligible to purchase all of the Collateral Debt
     Securities or any one or more (but not all) Collateral Debt Securities) to
     be provided to the Trustee by the Collateral Manager; (e) a detailed
     timetable; and (f) copies of all transfer documents provided to the Trustee
     by the Collateral Manager (including transfer certificates and subscription
     agreements which a bidder must execute pursuant to the underlying
     instruments and a list of the requirements which the bidder must satisfy
     under the underlying instruments (i.e., QIB status, Qualified Purchaser
     status, etc.)).

          (iv) The Collateral Manager will send solicitation packages to all
     Listed Bidders on the List at least 20 Business Days before the proposed
     Auction Call Redemption Date. The Listed Bidders will be required to submit
     any due diligence questions (or comments on the draft purchase agreement)
     in writing to the Collateral Manager by a date specified in the
     solicitation package. The Collateral Manager will be required to answer all
     reasonable and relevant questions by the date specified in the solicitation
     package and the Collateral Manager will distribute the questions and
     answers and the revised final Auction Purchase Agreement to all Listed
     Bidders (with a copy to the Issuer and the Trustee).

          (b) Auction Process.

          (i) Wells Fargo Bank, National Association or its Affiliates may, but
     shall not be required to, bid at the Auction. The Collateral Manager and
     its Affiliates may bid in the Auction if the Collateral Manager deems such
     bidding to be appropriate but is not required to do so.

          (ii) On the second Business Day prior to the Auction Date (the
     "Auction Bid Date"), all bids will be due by facsimile at the offices of
     the Trustee by 11:00 a.m. New York City time, with the winning bidder or
     bidders to be notified by 2:00 p.m. New York City time. All bids from
     Listed Bidders on the List will be due on the bid sheet contained in the
     solicitation package. Each bid shall be for the purchase and delivery to
     one


                                     -240-

<PAGE>

     purchaser (A) of all (but not less than all) of the Collateral Debt
     Securities or (B) of one or more (but not all) of the Collateral Debt
     Securities.

          (iii) Unless the Trustee receives (A) at least one bid from a Listed
     Bidder to purchase all of the Collateral Debt Securities or (B) receives
     bids from one or more Listed Bidders (to purchase one or more (but not all)
     Collateral Debt Securities) for all Collateral Debt Securities in the
     aggregate, the Trustee will decline to consummate the sale.

          (iv) Subject to clause (iii) above, with the advice of the Collateral
     Manager, the Trustee shall select the bid or bids which result in the
     Highest Auction Price from one or more Listed Bidders (in excess of the
     specified minimum purchase price). "Highest Auction Price" means the higher
     of (A) the highest price bid by any Listed Bidder for all of the Collateral
     Debt Securities or (B) the sum of the highest prices bid by one or more
     Listed Bidders (for one or more (but not all) Collateral Debt Securities)
     for all Collateral Debt Securities in the aggregate. In each case, the
     price bid by a Listed Bidder will be the dollar amount which the Collateral
     Manager certifies to the Trustee based on the Collateral Manager's review
     of the bids, which certification shall be binding and conclusive.

          (v) Upon notification to the winning bidder or bidders, the winning
     bidder (or, if the Highest Auction Price requires the sale of the
     Collateral Debt Securities to more than one bidder, each winning bidder)
     will be required to deliver to the Trustee a signed counterpart of the
     Auction Purchase Agreement no later than 4:00 p.m. New York City time on
     the Auction Date. The winning bidder (or, if the Highest Auction Price
     requires the sale of the Collateral Debt Securities to more than one
     bidder, each winning bidder) will make payment in full of the purchase
     price on the Business Day (the "Auction Purchase Closing Date") specified
     in the general solicitation package (which will be no later than ten
     Business Days prior to the proposed Auction Call Redemption Date). If a
     winning bidder so requests, the Trustee and the Issuer will enter into a
     bailee letter in the form agreed upon by the Trustee and the Collateral
     Manager to this Indenture (a "Bailee Letter") with each winning bidder and
     its designated bank (which bank will be subject to approval by the Issuer
     (or the Collateral Manager on behalf of the Issuer)); provided that such
     bank enters into an account control agreement with the Trustee and the
     Issuer and has a long term debt rating of at least "BBB+" by S&P's and (if
     rated by Fitch) at least "BBB+" by Fitch and (if rated by Moody's) at least
     "A2" by Moody's. If the above requirements are satisfied, the Trustee will
     deliver the Collateral Debt Securities (to be sold to such bidder) pursuant
     thereto to the bailee bank at least one Business Day prior to the closing
     on the sale of the Collateral Debt Securities and accept payment of the
     purchase price pursuant thereto. If payment in full of the purchase price
     is not made by the Auction Purchase Closing Date for any reason whatsoever
     (or, if the Collateral Debt Securities are to be sold to more than one
     bidder, if any bidder fails to make payment in full of the purchase price
     by the Auction Purchase Closing Date for any reason whatsoever), the Issuer
     will decline to consummate the sale of all Collateral Debt Securities, the
     Trustee and the Issuer will direct the bailee bank to return the Collateral
     Debt Securities to the Trustee, and (if notice of redemption has been given
     by the


                                     -241-

<PAGE>

     Trustee) the Trustee will give notice (in accordance with the terms of this
     Indenture) that the Auction Call Redemption will not occur.

          (vi) Notwithstanding the foregoing, but subject to the satisfaction of
     the conditions set forth in Section 9.2(b), the Holder of the Preferred
     Shares or any of its Affiliates, although it may not have been the highest
     bidder, will have the option to purchase any one or more Collateral Debt
     Securities for a purchase price equal to the highest bid therefor.

          (c) Notwithstanding anything to the contrary set forth in this Section
12.4, at the election of the Holder of the Preferred Shares, in lieu of
initiating or conducting any Auction, the Holder of the Preferred Shares or any
of its Affiliates will have the option to purchase all of the Collateral Debt
Securities that would otherwise be subject to such Auction for a price equal to
the Total Redemption Price. Such purchase of Collateral Debt Securities by the
Holder of the Preferred Shares or its Affiliates pursuant to this Section
12.4(c) will be deemed to be a Successful Auction pursuant to this Indenture and
the Notes and the Preferred Shares shall be redeemed, in whole and not in part,
at their applicable Redemption Prices in accordance with the applicable
provisions of Article 9.

          Section 12.5 Modifications to Collateral Quality Tests or Coverage
Tests.

          In the event any of the Rating Agencies modifies the definitions or
calculations relating to (i) the method of calculating any of its respective
Collateral Quality Tests included in clauses (xx) through (xxx) of the
Collateral Quality Tests (a "Collateral Quality Test Modification"), (ii) any of
the Coverage Tests (a "Coverage Test Modification") or (iii) its requirements
for pro rata "special amortizations" (a "Pro Rata Special Amortization
Modification"), in either case in order to correspond with published changes in
the guidelines, methodology or standards established by such Rating Agency, the
Issuer may, but is under no obligation solely as a result of this Section 12.5
to, incorporate corresponding changes into this Indenture by an amendment hereto
without the consent of the Holders of the Notes (except as provided below) (but
with written notice to the Noteholders) or the Preferred Shares if (x)(1) in the
case of a Collateral Quality Test Modification, the Rating Agency Condition is
satisfied with respect to the Rating Agency that made such modification or (2)
in the case of a Coverage Test Modification or a Pro Rata Special Amortization,
the Rating Agency Condition is satisfied with respect to each Rating Agency then
rating the Notes and (y) written notice of such modification is delivered by the
Collateral Manager to the Trustee, each Hedge Counterparty and to the Holders of
the Notes and Preferred Shares (which notice may be included in the next
regularly scheduled report to Noteholders). Any such Collateral Quality Test
Modification, Coverage Test Modification or Pro Rata Special Amortization, as
the case may be, shall be effected without execution of a supplemental
indenture; provided, however, that such amendment shall be (i) evidenced by a
written instrument executed and delivered by each of the Co-Issuers and the

to and in compliance with this Section 12.5 and (B) if requested by the Trustee,

this Section 12.5 and that all applicable conditions precedent under this
Section 12.5 have been satisfied, on which such Officer's Certificate or such
Officer's Certificate and

Opinion of Counsel, as the case may be, the Trustee shall be entitled to rely.
Notwithstanding the foregoing, so long as MBIA is deemed to be the Controlling
Class hereunder, the Issuer will not be permitted to make any such change with
respect to Moody's or Fitch or, on or after the date that is 18 months after the
Closing Date, S&P, without obtaining the consent of MBIA (such consent not to be
unreasonably withheld); provided that, if MBIA does not object to such change
within 14 days after notice thereof is given, MBIA will be deemed to have
consented to such change. Notwithstanding the foregoing, any such amendment
reasonably determined by the Trustee to be unduly burdensome to the Trustee,
shall not take effect without the Trustee's express written consent.

                                  MISCELLANEOUS

          Section 14.1 Form of Documents Delivered to the 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 Authorized Officer of the Issuer or
the Co-Issuer may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless such
Authorized Officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the


                                     -247-

<PAGE>

matters upon which his certificate or opinion is based are erroneous. Any such
certificate of an Authorized Officer of the Issuer or the Co-Issuer or Opinion
of Counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, the Issuer, the Co-Issuer, the
Collateral Manager or any other Person, stating that the information with
respect to such factual matters is in the possession of the Issuer, the
Co-Issuer, the Collateral Manager or such other Person, unless such Authorized
Officer of the Issuer or the Co-Issuer or such counsel knows that the
certificate or opinion or representations with respect to such matters are
erroneous. Any Opinion of Counsel also may be based, insofar as it relates to
factual matters, upon a certificate or opinion of, or representations by, an
Authorized Officer of the Issuer or the Co-Issuer, stating that the information
with respect to such matters is in the possession of the Issuer or the
Co-Issuer, 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.

          Whenever in this Indenture it is provided that the absence of the
occurrence and continuation of a Default or Event of Default is a condition
precedent to the taking of any action by the Trustee at the request or direction
of the Issuer or the Co-Issuer, then notwithstanding that the satisfaction of
such condition is a condition precedent to the Issuer's or the Co-Issuer's
rights to make such request or direction, the Trustee shall be protected in
acting in accordance with such request or direction if it does not have
knowledge of the occurrence and continuation of such Default or Event of Default
as provided in Section 6.1(e).

          Section 14.2 Acts of Securityholders.

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Securityholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Securityholders in person or by an
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
Issuer and/or the Co-Issuer. Such instrument or instruments (and the action or
actions embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Securityholders 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, the Issuer and the Co-Issuer, if made in the manner
provided in this Section 14.2.

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

          (c) The principal amount and registered numbers of Notes held by any
Person, and the date of his holding the same, shall be proved by the Notes
Register. The Notional Amount and registered numbers of the Preferred Shares
held by any Person, and the date of his holding the same, shall be proved by the
register maintained with respect to the Preferred Shares.


                                     -248-

<PAGE>

          (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Securityholder shall bind such Securityholder (and
any transferee thereof) of such Security and of every Security 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, the Preferred
Shares Paying Agent, the Share Registrar, the Issuer or the Co-Issuer in
reliance thereon, whether or not notation of such action is made upon such
Security.

          Section 14.4 Notices to Noteholders; Waiver.

          Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Notes of any event,

          (a) such notice shall be sufficiently given to Holders of Notes if in
writing and mailed, first class postage prepaid, to each Holder of a Note
affected by such event, at the address of such Holder as it appears in the Notes
Register, not earlier than the earliest date and not later than the latest date,
prescribed for the giving of such notice;

          (b) such notice shall be in the English language;

          (c) such notice shall also be provided to the Irish Paying Agent (for
so long as any Notes are listed on the Irish Stock Exchange); and

          (d) all reports or notices to Preferred Shareholders shall be
sufficiently given if provided in writing and mailed, first class postage
prepaid, to the Preferred Shares Paying Agent.

          Notwithstanding clause (a) above, a Holder of Notes may give the
Trustee written notice that it is requesting that notices to it be given by
facsimile transmissions and stating the facsimile number for such transmission.
Thereafter, the Trustee shall give notices to such Holder by facsimile
transmission; provided that if such notice also requests that notices be given
by mail, then such notice shall also be given by mail in accordance with clause
(a) above.


                                     -251-

<PAGE>

          The Trustee shall deliver to the Holders of the Notes any information
or notice requested to be so delivered by at least 25% of the Holders of any
Class of Notes.

          Neither the failure to mail any notice, nor any defect in any notice
so mailed, to any particular Holder of a Note shall affect the sufficiency of
such notice with respect to other Holders of Notes. In case by reason of the
suspension of regular mail service or by reason of any other cause, it shall be
impracticable to give such notice by mail, then such notification to Holders of
Notes shall be made with the approval of the Trustee and shall constitute
sufficient notification to such Holders of Notes for every purpose hereunder.

          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 Noteholders 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 the 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 Noteholders when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be a sufficient giving of such notice.

          For so long as any Notes are listed on the Irish Stock Exchange and
the rules of such exchange so require, all notices to Noteholders of such Notes
will be published in the Daily Official List of the Irish Stock Exchange.

          Section 14.5 Effect of Headings and Table of Contents.

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

          Section 14.6 Successors and Assigns.

          All covenants and agreements in this Indenture by the Issuer and the
Co-Issuer shall bind their respective successors and assigns, whether so
expressed or not.

          Section 14.7 Severability.

          In case any provision in this Indenture or in the Notes 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 14.8 Benefits of Indenture.

          Nothing in this Indenture or in the Securities, expressed or implied,
shall give to any Person, other than (i) the parties hereto and their successors
hereunder and (ii) the Collateral Manager, each Hedge Counterparty, the
Preferred Shareholders, the Preferred Shares Paying Agent, the Share Registrar
and the Noteholders (each of whom, in the case of this clause (ii),


                                     -252-

shall be an express third party beneficiary hereunder), any benefit or any legal
or equitable right, remedy or claim under this Indenture.

          Section 14.9 Governing Law.

          THIS INDENTURE AND EACH NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO
BE PERFORMED THEREIN WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

          Section 14.10 Submission to Jurisdiction.

          Each of the Issuer and the Co-Issuer hereby irrevocably submits to the
non-exclusive jurisdiction of any New York State or federal court sitting in the
Borough of Manhattan in The City of New York in any action or proceeding arising
out of or relating to the Notes or this Indenture, and each of the Issuer and
the Co-Issuer hereby irrevocably agrees that all claims in respect of such
action or proceeding may be heard and determined in such New York State or
federal court. Each of the Issuer and the Co-Issuer hereby irrevocably waives,
to the fullest extent that they may legally do so, the defense of an
inconvenient forum to the maintenance of such action or proceeding. Each of the
Issuer and the Co-Issuer irrevocably consents to the service of any and all
process in any action or proceeding by the mailing or delivery of copies of such
process to it at the office of the Issuer's and the Co-Issuer's agent set forth
in Section 7.2. Each of the Issuer and the Co-Issuer agrees that a final
judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.

          Section 14.11 Counterparts.

          This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

          Section 14.12 Liability of Co-Issuers.

          Notwithstanding any other terms of this Indenture, the Notes or any
other agreement entered into between, inter alios, the Issuer and the Co-Issuer
or otherwise, neither the Issuer nor the Co-Issuer shall have any liability
whatsoever to the Co-Issuer or the Issuer, respectively, under this Indenture,
the Notes, any such agreement or otherwise and, without prejudice to the
generality of the foregoing, neither the Issuer nor the Co-Issuer shall be
entitled to take any steps to enforce, or bring any action or proceeding, in
respect of this Indenture, the Notes, any such agreement or otherwise against
the other Co-Issuer or the Issuer, respectively. In particular, neither the
Issuer nor the Co-Issuer shall be entitled to petition or take any other steps
for the winding up or bankruptcy of the Co-Issuer or the Issuer, respectively or
shall have any claim in respect of any assets of the Co-Issuer or the Issuer,
respectively.

   ASSIGNMENT OF COLLATERAL DEBT SECURITIES PURCHASE AGREEMENTS AND COLLATERAL
                              MANAGEMENT AGREEMENT

          Section 15.1 Assignment of Collateral Debt Securities Purchase
Agreement and the Collateral Management Agreement.

          (a) The Issuer, in furtherance of the covenants of this Indenture and
as security for the Notes and amounts payable to the Secured Parties hereunder
and the performance and observance of the provisions hereof, hereby collaterally
assigns, transfers, conveys and sets over to the Trustee, for the benefit of the
Noteholders and each Hedge Counterparty, all of the Issuer's estate, right,
title and interest in, to and under each Collateral Debt Securities Purchase
Agreement (now or hereafter entered into) and the Collateral Management
Agreement (each, an "Article 15 Agreement"), including, without limitation, (i)
the right to give all notices, consents and releases thereunder, (ii) the right
to give all notices of termination and to take any legal action upon the breach
of an obligation of a Seller or the Collateral Manager thereunder, including the
commencement, conduct and consummation of proceedings at law or in equity, (iii)
the right to receive all notices, accountings, consents, releases and statements
thereunder and (iv) the right to do any and all other things whatsoever that the
Issuer is or may be entitled to do thereunder; provided, however, that the
Trustee hereby grants the Issuer a license to exercise all of the Issuer's
rights pursuant to the Article 15 Agreements without notice to or the consent of
the Trustee (except as otherwise expressly required by this Indenture,
including, without limitation, as set forth in Section 15.1(f)) which license
shall be and is hereby deemed to be automatically revoked upon the occurrence of
an Event of Default hereunder until such time, if any, that such Event of
Default is cured or waived.

          (b) The assignment made hereby is executed as collateral security, and
the execution and delivery hereby shall not in any way impair or diminish the
obligations of the Issuer under the provisions of each of the Article 15
Agreements, nor shall any of the obligations contained in each of the Article 15
Agreements be imposed on the Trustee.

          (c) Upon the retirement of the Notes, the payment by the Issuer of all
amounts payable under each Hedge Agreement and the release of the Assets from
the lien of this Indenture, this assignment and all rights herein assigned to
the Trustee for the benefit of the Noteholders and each Hedge Counterparty shall
cease and terminate and all the estate, right, title and interest of the Trustee
in, to and under each of the Article 15 Agreements shall revert to the Issuer
and no further instrument or act shall be necessary to evidence such termination
and reversion.

          (d) The Issuer represents that it has not executed any assignment of
any of the Article 15 Agreements other than this collateral assignment.

          (e) The Issuer agrees that this assignment is irrevocable, and that it
shall not take any action which is inconsistent with this assignment or make any
other assignment inconsistent herewith. The Issuer shall, from time to time upon
the request of the Trustee, execute all instruments of further assurance and all
such supplemental instruments with respect to this assignment as the Trustee may
specify.


                                     -254-

<PAGE>

          (f) The Issuer hereby agrees, and hereby undertakes to obtain the
agreement and consent of the Sellers and the Collateral Manager, as applicable,
in the Collateral Debt Securities Purchase Agreements and the Collateral
Management Agreement, as applicable, to the following:

          (i) each of the Sellers and the Collateral Manager consents to the
     provisions of this collateral assignment and agrees to perform any
     provisions of this Indenture made expressly applicable to each of the
     Sellers and the Collateral Manager pursuant to the applicable Article 15
     Agreement;

          (ii) each of the Sellers and the Collateral Manager, as applicable,
     acknowledges that the Issuer is collaterally assigning all of its right,
     title and interest in, to and under the Collateral Debt Securities Purchase
     Agreements and the Collateral Management Agreement, as applicable, to the
     Trustee for the benefit of the Noteholders and each Hedge Counterparty, and
     each of the Sellers and the Collateral Manager, as applicable, agrees that
     all of the representations, covenants and agreements made by each of the
     Sellers and the Collateral Manager, as applicable, in the applicable
     Article 15 Agreement are also for the benefit of, and enforceable by, the
     Trustee, the Noteholders and each Hedge Counterparty;

          (iii) each of the Sellers and the Collateral Manager, as applicable,
     shall deliver to the Trustee duplicate original copies of all notices,
     statements, communications and instruments delivered or required to be
     delivered to the Issuer pursuant to the applicable Article 15 Agreement;

          (iv) none of the Issuer, the Sellers or the Collateral Manager shall
     enter into any agreement amending, modifying or terminating the applicable
     Article 15 Agreement, (other than in respect of an amendment or
     modification to cure any inconsistency, ambiguity or manifest error) or
     selecting or consenting to a successor collateral manager, as applicable,
     without notifying each Rating Agency and without the prior written consent
     and written confirmation of each Rating Agency that such amendment,
     modification or termination will not cause its then-current ratings of the
     Notes to be reduced;

          (v) except as otherwise set forth herein and therein (including,
     without limitation, pursuant to Sections 12 and 13 of the Collateral
     Management Agreement), the Collateral Manager shall continue to serve as
     Collateral Manager under the Collateral Management Agreement,
     notwithstanding that the Collateral Manager shall not have received amounts
     due it under the Collateral Management Agreement because sufficient funds
     were not then available hereunder to pay such amounts pursuant to the
     Priority of Payments. The Collateral Manager agrees not to cause the filing
     of a petition in bankruptcy against the Issuer for the nonpayment of the
     fees or other amounts payable to the Collateral Manager under the
     Collateral Management Agreement until the payment in full of all Notes
     issued under this Indenture and the expiration of a period equal to the
     applicable preference period under the Bankruptcy Code plus ten days
     following such payment; and


                                     -255-

<PAGE>

          (vi) the Collateral Manager irrevocably submits to the non-exclusive
     jurisdiction of any New York State or federal court sitting in the Borough
     of Manhattan in The City of New York in any action or proceeding arising
     out of or relating to the Notes or this Indenture, and the Collateral
     Manager irrevocably agrees that all claims in respect of such action or
     proceeding may be heard and determined in such New York State or federal
     court. The Collateral Manager irrevocably waives, to the fullest extent it
     may legally do so, the defense of an inconvenient forum to the maintenance
     of such action or proceeding. The Collateral Manager irrevocably consents
     to the service of any and all process in any action or Proceeding by the
     mailing by certified mail, return receipt requested, or delivery requiring
     signature and proof of delivery of copies of such initial process to it at
     Arbor Realty Trust, Inc., 333 Earle Ovington Boulevard, 9th Floor,
     Uniondale, New York 11553, Attention: Executive Vice President--Structured
     Securitization. The Collateral Manager agrees that a final and
     non-appealable judgment by a court of competent jurisdiction in any such
     action or proceeding shall be conclusive and may be enforced in other
     jurisdictions by suit on the judgment or in any other manner provided by
     law.

    HEDGE AGREEMENT; CURE RIGHTS; PURCHASE RIGHTS; SUBSEQUENT COLLATERAL DEBT
                                   SECURITIES

          Section 16.1 Issuer's Obligations under Hedge Agreement.

          (a) On the Closing Date and thereafter, and on and after any date on
which the Issuer enters into an additional or replacement Hedge Agreement
(including any related Hedge Counterparty Credit Support), the Issuer, as
directed by the Collateral Manager, shall (i) require that each Hedge
Counterparty thereto, or any third party (including an Affiliate of such Hedge
Counterparty) that (A) has absolutely and unconditionally guaranteed, pursuant
to a guarantee that satisfies S&P's published criteria on guarantees, the
obligations of the Hedge Counterparty under the related Hedge Agreement (with
such form of guaranty as shall be satisfactory to each Rating Agency then rating
any Notes hereunder), (B) has entered into credit intermediation arrangements in
respect of the obligations of the Hedge Counterparty under the related Hedge
Agreement satisfactory to each Rating Agency then rating any Notes hereunder,
(C) is the issuing bank on one or more letters of credit supporting the
obligations of the Hedge Counterparty under the related Hedge Agreement and that
shall be reasonably acceptable to each Rating Agency then rating any Notes
hereunder or (D) has provided any other additional credit support and such
inclusion of additional credit support shall have satisfied the Rating Agency
Condition and, so long as MBIA is deemed to be the Controlling Class hereunder,
MBIA consents (any such third party, including an Affiliate of such Hedge
Counterparty, a "Hedge Counterparty Credit Support Provider") has, at the time
the Hedge Agreement is executed, with respect to itself as an issuer or with
respect to its indebtedness, credit ratings at least equal to the Hedge
Counterparty Collateral Threshold Ratings by each Rating Agency then rating any
Notes hereunder, (ii) except with respect to a Form-Approved Asset Specific
Hedge, obtain a written confirmation from each Rating Agency then rating any
Notes hereunder that any additional or replacement Hedge Agreement and the
related Hedge Counterparty would not cause such Rating


                                     -256-

<PAGE>

Agency's then-current rating on any Class of Notes to be adversely qualified,
reduced, suspended or withdrawn and (iii) assign and grant a security interest
in such Hedge Agreement to the Trustee pursuant to this Indenture. Each Hedge
Agreement will provide that no amendment, modification or waiver in respect of
such Hedge Agreement, including any additional or replacement Hedge Agreement,
will be effective unless (A) evidenced by a writing executed by each party
thereto, (B) the Trustee has acknowledged its consent thereto in writing and (C)
each Rating Agency confirms that such amendment, modification or waiver will not
cause the reduction or withdrawal of its then-current rating on any Class of
Notes. For the avoidance of doubt, the Issuer may enter into any Hedge Agreement
with respect to which the Rating Agency Condition is satisfied and, so long as
MBIA is deemed to be the Controlling Class hereunder, MBIA has consented. In
addition, so long as MBIA is deemed to be the Controlling Class hereunder, the
Issuer shall provide MBIA with a copy of any Hedge Agreement.

          (b) The Trustee shall, on behalf of the Issuer, pay amounts due to
each Hedge Counterparty under the related Hedge Agreements in accordance with
the Priority of Payments, Section 11.1(f) hereof and Section 16.1(g) hereof.

          (c) The notional amount schedule of each Hedge Agreement providing for
floating rate payments to the Issuer will be calculated as a percentage of the
principal amount of the Notes originally anticipated to be Outstanding on each
Payment Date based on certain assumptions. In accordance with the terms of each
Hedge Agreement (other than any interest rate basis swap agreements), such
notional amount schedule will be reduced by the Issuer (or the Collateral
Manager on behalf of the Issuer) or each Hedge Counterparty on each Payment Date
to the extent that (i) the outstanding principal amount of the Notes is less
than the scheduled aggregate notional amount of the related Hedge Agreements
(other than any interest rate basis swap agreements) for such Payment Date
and/or (ii) the Net Outstanding Portfolio Balance is less than the scheduled
aggregate notional amount of the related Hedge Agreements (other than any
interest rate basis swap agreements) for such Payment Date; provided that if any
Notes are then Outstanding, the Trustee shall first have received written
evidence that the Rating Agency Condition with respect to Moody's and S&P has
been satisfied with respect to such reduction (other than as originally
scheduled pursuant to the terms of the Hedge Agreement) and the giving of notice
to Fitch and, so long as MBIA is the Controlling Class hereunder, MBIA, of such
reduction other than a scheduled reduction. Additionally, subject to
satisfaction of the Rating Agency Condition with respect to Moody's and S&P and
the notification of Fitch and, so long as MBIA is the Controlling Class
hereunder, MBIA, in respect thereof, a termination in part of a Hedge Agreement
and a corresponding reduction in the notional amount of the Hedge Agreement may
occur, in the event of a Mandatory Redemption or Special Amortization of the
Notes. The Issuer's remaining obligations in accordance with the Priority of
Payments will not be affected by any such reduction. Notwithstanding any right
of the Issuer to terminate each Hedge Agreement upon the occurrence of a
Termination Event or an Event of Default (each as defined in each Hedge
Agreement) or otherwise pursuant to a Hedge Agreement, the Issuer shall not (x)
terminate any Hedge Agreement or (y) cause the non-replacement of any terminated
Hedge Agreement, unless in each case the Issuer notifies Fitch thereof and
obtains a written confirmation from Moody's and S&P that such termination or
non-replacement, as applicable, would not cause such Rating Agency's
then-current rating on any Class of Notes, as applicable, to be adversely
qualified, reduced, suspended or withdrawn. For the avoidance of doubt, subject
to the consent of the related Hedge Counterparty if required in the Hedge
Agreement, the Issuer


                                     -257-

<PAGE>

may terminate, reduce the notional amount of or otherwise modify the terms of
any Hedge Agreement if the Rating Agency Condition is satisfied in connection
therewith.

          (d) Each Hedge Agreement shall provide for termination, and shall be
capable of being terminated (i) by or on behalf of the Issuer upon the failure
of the related Hedge Counterparty to, unless the Rating Agency Condition is
satisfied, post collateral under a Hedge Counterparty Credit Support within the
time period specified in the related Hedge Agreement or provide other alternate
credit enhancement in accordance with the related Hedge Agreement, or upon the
failure of the related Hedge Counterparty to make a Permitted Transfer (at the
Hedge Counterparty's sole cost and expense) of all of its rights and obligations
under the related Hedge Agreement within the time period specified in the
related Hedge Agreement, after the failure of the related Hedge Counterparty (or
any Hedge Counterparty Credit Support Provider) to have the Hedge Counterparty
Collateral Threshold Ratings; (ii) by or on behalf of the Issuer upon the
failure of the related Hedge Counterparty to make a Permitted Transfer (at the
related Hedge Counterparty's sole cost and expense) of all of its rights and
obligations under the related Hedge Agreement within the time period specified
in the related Hedge Agreement after the failure of the related Hedge
Counterparty (or any Hedge Counterparty Credit Support Provider) to have the
Hedge Counterparty Required Ratings (provided, however, that the related Hedge
Counterparty shall continue to post collateral and use its best efforts to find
a replacement pursuant to the related Hedge Agreement until the earlier to occur
of termination of the related Hedge Agreement by or on behalf of the Issuer or
consummation of a Permitted Transfer) unless the Rating Agency Condition has
been satisfied with respect to such termination, (iii) by the related Hedge
Counterparty, upon the failure of the Issuer to make, when due, any scheduled
periodic payments under the related Hedge Agreement, (iv) in whole or in part,
as provided in the related Hedge Agreement, upon the final sale of the Assets,
an Auction Call Redemption, an Optional Redemption, a Clean-up Call or a Tax
Redemption, (v) in part, as provided in the related Hedge Agreement, subject to
satisfaction of the Rating Agency Condition with respect to Moody's and S&P,
and, so long as MBIA is deemed to be the Controlling Class hereunder, the
consent of MBIA, upon a Mandatory Redemption, a Special Amortization or a Rating
Confirmation Failure, unless there will be sufficient Interest Proceeds on the
following Payment Date to pay in full any termination payment due from the
Issuer in connection therewith plus all of the amounts required to be paid by
the Issuer on such Payment Date pursuant to clauses (1) through (28) of Section
11.1(a)(i) or (vi) as otherwise expressly provided for in the related Hedge
Agreement. The Issuer shall satisfy the Rating Agency Condition with respect to
Moody's and S&P and, so long as MBIA is deemed to be the Controlling Class
hereunder, give notice to MBIA with respect to any transfer of all of the rights
and obligations of any Hedge Counterparty under any Hedge Agreement.

          (e) The Trustee shall, promptly after the Closing Date, establish a
single, segregated trust account with respect to each Hedge Counterparty in the
name of the Trustee, each designated as the "Hedge Collateral Account," which
shall be held in trust for the benefit of the Noteholders and the applicable
Hedge Counterparty, over which the Trustee shall have exclusive control and the
sole right of withdrawal, and in which no Person other than the Trustee and the
Noteholders and the applicable Hedge Counterparty shall have any legal or
beneficial interest. The Trustee shall deposit all collateral received from the
related Hedge Counterparty under the related Hedge Agreement in the related
Hedge Collateral Account. Any and all funds at any time on deposit in, or
otherwise to the credit of, each Hedge Collateral Account shall be

held in trust by the Trustee for the benefit of the Noteholders and for the
related Hedge Counterparty in accordance with the terms of the Hedge Agreement.
The only permitted withdrawal from or application of funds on deposit in, or
otherwise to the credit of, each Hedge Collateral Account shall be (i) for
application to obligations of the applicable Hedge Counterparty to the Issuer
under the related Hedge Agreement in accordance with the terms of such Hedge
Agreement or (ii) to return collateral to the applicable Hedge Counterparty when
and as required by the related Hedge Agreement, which the Trustee shall return
to the applicable Hedge Counterparty in accordance with the related Hedge
Agreement. Each Hedge Collateral Account shall remain at all times with the
Corporate Trust Office or a financial institution having a long-term debt rating
at least equal to "A-" or "A2," as applicable, or a short-term debt rating at
least equal to "A-1," "P-1" or "F1," as applicable.

          (f) Upon the default by a Hedge Counterparty in the payment when due
of its obligations to the Issuer under the related Hedge Agreement (following
the expiration of any applicable grace period), the Trustee shall forthwith
provide facsimile notice thereof to the Issuer, the Collateral Manager, each of
the Rating Agencies and, if applicable, any Hedge Counterparty Credit Support
Provider. When the Trustee becomes aware of such default, the Trustee shall make
a demand on the applicable Hedge Counterparty, or any Hedge Counterparty Credit
Support Provider, if applicable, demanding payment forthwith. The Trustee shall
give notice to the Noteholders and further notice to the Collateral Manager upon
the continuing failure by such Hedge Counterparty or any Hedge Counterparty
Credit Support Provider to perform its obligations during the two Business Days
following a demand made by the Trustee on such Hedge Counterparty or any such
Hedge Counterparty Credit Support Provider.

          (g) Upon the termination or partial termination of each Hedge
Agreement, the Issuer at the direction of the Collateral Manager and the Trustee
shall take such commercially reasonable actions (following the expiration of any
applicable grace period and after the expiration of the applicable time period
set forth in the related Hedge Agreement) to enforce the rights of the Issuer
and the Trustee thereunder as may be permitted by the terms of the related Hedge
Agreement and consistent with the terms hereof, and shall apply the proceeds of
any such actions (including, without limitation, the proceeds of the liquidation
of any collateral pledged by or on behalf of each Hedge Counterparty) to enter
into an additional or replacement Hedge Agreements within 30 days of the
expiration of any such grace period and such applicable time period as set forth
in the related Hedge Agreement on substantially identical terms or on such other
terms as required by the related Hedge Counterparty to any such additional or
replacement Hedge Agreement subject to the Rating Agency Condition and, so long
as MBIA is deemed to be the Controlling Class hereunder, the consent of MBIA.
The Trustee shall, promptly after the Closing Date, in respect of each Hedge
Counterparty, establish a single segregated trust account in the name of the
Trustee, each designated the "Hedge Termination Account," which shall be held in
trust for the benefit of the Noteholders and each Hedge Counterparty and over
which the Trustee will have exclusive control and the sole right of withdrawal,
and in each of which no person other than the Trustee, the Noteholders and the
Hedge Counterparty will have any legal or beneficial interest. Each Hedge
Termination Account shall remain at all times with the Corporate Trust Office or
a financial institution having a long-term debt rating at least equal to "A-" or
"A2," as applicable, or a short-term debt rating at least equal to "A-1," "P-1"
or "F1," as applicable. Notwithstanding anything contained in this Indenture to
the contrary, any payments (other than payments relating to past-due scheduled
payments on a Hedge Agreement) received


                                     -259-

<PAGE>

by the Issuer or Trustee in connection with either (x) the termination (in whole
or in part) of a related Hedge Agreement or (y) the execution of an additional
or replacement Hedge Agreements shall be immediately transferred to the Trustee
for deposit into the related Hedge Termination Account. Any costs attributable
to entering into an additional or replacement Hedge Agreements (other than in
connection with a Permitted Transfer) with respect to the related Hedge
Counterparty shall be paid from the related Hedge Termination Account, and any
such amounts which are payable but exceed the balance on deposit in the related
Hedge Termination Account shall be borne solely by the Issuer and constitute
amounts payable under clause (28) of Section 11.1(a)(i) hereof. Additionally,
any amounts that are due and payable to a Hedge Counterparty upon a termination
of a Hedge Agreement shall be paid from any amounts on deposit in the related
Hedge Termination Account, and, to the extent the amounts on deposit in such
Hedge Termination Account are insufficient to pay all such amounts, then such
amounts will be payable in accordance with Section 11.1(a) hereof. Any amounts
remaining on deposit in a Hedge Termination Account related to a Hedge Agreement
following payment to the Hedge Counterparty shall be transferred to the
Principal Collection Account and shall constitute Principal Proceeds. If
determining the amount payable under the terminated Hedge Agreement, the Issuer
(or the Collateral Manager on behalf of the Issuer) shall seek quotations in
accordance with the terms of the related Hedge Agreement from reference
market-makers whose ratings are at least equal to the Hedge Counterparty
Collateral Threshold Ratings. Each Hedge Agreement may provide that the
applicable Hedge Counterparty is responsible for determining the amounts payable
in certain circumstances. In addition, the Issuer (or the Collateral Manager on
behalf of the Issuer) shall use commercially reasonable efforts to cause the
termination of the related Hedge Agreement to become effective simultaneously
with the effectiveness of a replacement thereto, described as aforesaid.

          Section 16.2 Collateral Debt Securities Purchase Agreements.

          Following the Closing Date, unless a Collateral Debt Securities
Purchase Agreement is necessary to comply with the provisions of this Indenture,
the Issuer may acquire Collateral Debt Securities in accordance with customary
settlement procedures in the relevant markets. In any event, the Issuer (or the
Collateral Manager on behalf of the Issuer) shall obtain from any seller of a
Loan, all Underlying Instruments with respect to each Collateral Debt Security,
and all Underlying Instruments related to any related Senior Tranche that
govern, directly or indirectly, the rights and obligations of the owner of the
Collateral Debt Security with respect to the Underlying Term Loan, the
Underlying Mortgage Property and the Collateral Debt Security and any
certificate evidencing the Collateral Debt Security.

          Section 16.3 Cure Rights.

          (a) If the Issuer, as holder of a Loan, has the right pursuant to the
related Underlying Instruments to cure an event of default on the Underlying
Term Loan, the Collateral Manager may, in accordance with the Collateral Manager
Servicing Standard and subject to the applicable provisions of the Servicing
Agreement, advance from its own funds with respect to the Loan as a reimbursable
Cure Advance, all such amounts as are necessary to effect the timely cure of
such event of default pursuant to the terms of the related Underlying
Instruments; provided that (i) such advances may only be made to the extent that
the Collateral Manager reasonably believes that such Cash advance can be repaid
from future payments on the related


                                     -260-

<PAGE>

underlying commercial mortgage loan (subject to the Collateral Manager Servicing
Standard and to the applicable provisions of the Servicing Agreement) and (ii)
the particular advance would not, if made, constitute a Nonrecoverable Cure
Advance. The determination by the Collateral Manager that it has made a
Nonrecoverable Cure Advance or that any proposed Cure Advance, if made, would
constitute a Nonrecoverable Cure Advance shall be made by the Collateral Manager
in its reasonable, good faith judgment (subject to the Collateral Manager
Servicing Standard and to the applicable provisions of the Servicing Agreement)
and shall be evidenced by an Officer's Certificate delivered promptly to the
Trustee, setting forth the basis for such determination, accompanied by an
appraisal, if available, or an independent broker's opinion of the value of the
Underlying Mortgage Property and any information that the Collateral Manager may
have obtained and that supports such determination. The Collateral Manager will
be entitled to reimbursement from any subsequent payments or recoveries on each
Collateral Debt Security in respect of which it makes a Cure Advance in
accordance with the Priority of Payments if such reimbursement would not cause
an Interest Shortfall; provided that, if at any time the Collateral Manager
shall determine (subject to the applicable provisions of the Servicing
Agreement) that a Cure Advance previously made is a Nonrecoverable Cure Advance,
the Collateral Manager shall be entitled to reimbursements for such
Nonrecoverable Cure Advance from subsequent payments or collections with respect
to the Assets on any Business Day during any Interest Accrual Period prior to
the related Determination Date (or on a Payment Date prior to any payment of
interest on or principal of the Notes in accordance with the Priority of
Payments). Notwithstanding the foregoing, the Collateral Manager will be
permitted (but not obligated) to defer or otherwise structure the timing of
recovery of any Nonrecoverable Cure Advance in such manner as the Collateral
Manager determines is in the best interest of the Holders of the Class A Notes
and the Class B Notes, as a collective whole, which may include being reimbursed
for such Nonrecoverable Cure Advance in installments.

          (b) No later than 11:00 a.m. on the Business Day preceding each
Determination Date, the Collateral Manager may request by Officer's Certificate
delivered to the Trustee, reimbursement for any (i) Cure Advance or (ii)
Nonrecoverable Cure Advance, from any amounts received with respect to the
related Collateral Debt Security or the Assets, respectively. No later than the
Payment Date related to the Determination Date for which the Collateral Manager
has delivered an Officer's Certificate requesting reimbursement of a Cure
Advance or a Nonrecoverable Cure Advance, the Trustee shall transfer to the
Collateral Manager, by wire transfer to an account identified to the Trustee in
writing, the amount of such Cure Advance or Nonrecoverable Cure Advance, as
applicable.

          (c) Notwithstanding anything to the contrary set forth herein, the
Collateral Manager shall not be required to make any Cure Advance that it
determines in its reasonable, good faith judgment would constitute a
Nonrecoverable Cure Advance as determined pursuant to Section 16.3(a).

          Section 16.4 Purchase Right; Holder of a Majority of the Preferred
Shares.

          If the Issuer, as holder of a Participation or B Note, has the right
pursuant to the related Underlying Instruments to purchase any related Senior
Tranche(s), the Issuer may, and shall if directed by the Holder of a Majority of
the Preferred Shares, exercise such right, if the Collateral Manager determines,
in accordance with the Collateral Manager Servicing Standard,


                                     -261-

<PAGE>

that the exercise of the option would be in the best interest of the
Noteholders, but may not exercise such right if the Collateral Manager
determines otherwise. The Collateral Manager shall deliver to the Trustee an
Officer's Certificate certifying such determination, accompanied by an Act of
the Holder of a Majority of the Preferred Shares directing the Issuer to
exercise such right. In connection with the purchase of any such Senior
Tranche(s), the Issuer shall assign to the Holder of a Majority of the Preferred
Shares or its designee all of its right, title and interest in such Senior
Tranche(s) in exchange for a purchase price (such price and any other associated
expense of such exercise to be paid by the Holder of a Majority of the Preferred
Shares) of the Senior Tranche(s) (or, if the Underlying Instruments permit, the
Issuer may assign the purchase right to the Holder of a Majority of the
Preferred Shares or its designee; otherwise the Holder of a Majority of the
Preferred Shares or its designee shall fund the purchase by the Issuer, which
shall then assign the Senior Tranche(s) to the Holder of a Majority of the
Preferred Shares or its designee) (the "Purchase Option Purchase Price"), which
amount shall be delivered by such Holder or its designee from its own funds to
or upon the instruction of the Collateral Manager in accordance with terms of
the Underlying Instruments related to the acquisition of such Senior Tranche(s).
The Trustee or the Issuer shall execute and deliver at the direction of such
Holder of a Majority of the Preferred Shares such instruments of transfer or
assignment prepared by such Holder, in each case without recourse, as shall be
necessary to transfer title to such Holder of the Majority of Preferred Shares
or its designee of the Senior Tranche(s) and the Trustee shall have no
responsibility with regard to such Senior Tranche(s).

          Section 16.5 Representations and Warranties Related to Subsequent
Collateral Debt Securities.

          (a) If the Collateral Debt Security is a Subsequent Collateral Debt

any modification, limitation or qualification that the Collateral Manager
determines to be reasonably acceptable in accordance with the Collateral Manager
Servicing Standard; provided that the Collateral Manager will provide each

such affected representation or warranty and the modification, exception,
limitation or qualification received with respect to the acquisition of any
Subsequent Collateral Debt Security during the period covered by the Monthly

to perform its obligations under, or on the validity or enforceability of, the
provisions of this Indenture applicable to the Advancing Agent;

          (b) the Advancing Agent has full power and authority to execute,

or hereafter in effect relating to creditors' rights and (ii) general principles
of equity (regardless of whether such enforcement is considered in a proceeding
in equity or at law);

          (c) neither the execution and delivery of this Indenture nor the

will violate or result in a breach or violation of any of the terms or
provisions of, or constitutes a default under: (i) the Articles of Incorporation
and bylaws of the Advancing Agent, (ii) the terms of any indenture, contract,

perform its obligations under this Indenture;

          (d) no litigation is pending or, to the best of the Advancing Agent's

Collateral Manager may, and at the direction of the Controlling Class shall,
terminate such Advancing Agent and replace such Advancing Agent with a successor
advancing agent the appointment of which satisfies the Rating Agency Condition
and, so long as MBIA is deemed to be the Controlling Class hereunder, to which
MBIA consents. In the event that the Collateral Manager has not terminated and
replaced such Advancing Agent within 30 days of such Advancing Agent's failure
to make a required Interest Advance, the Trustee may terminate such Advancing
Agent and appoint a successor Advancing Agent.

Agent shall be appointed only subject to satisfaction of the Rating Agency
Condition, upon the written consent of a Majority of the Preferred Shares and,
so long as MBIA is deemed to be the Controlling Class hereunder, the consent of
MBIA. If no successor Advancing Agent shall have been appointed and an
instrument of acceptance by a successor Advancing Agent shall not have been
delivered to the Advancing Agent within 30 days after the giving of such notice
of resignation, the resigning Advancing Agent, the Trustee or any Preferred
Shareholder, on behalf of himself and all others similarly situated, may
petition any court of competent jurisdiction for the appointment of a successor
Advancing Agent.

          (f) The Issuer and the Co-Issuer shall give prompt notice of each
resignation and each removal of the Advancing Agent and each appointment of a
successor Advancing Agent by mailing written notice of such event by first class
mail, postage prepaid, to each Rating Agency, each Hedge Counterparty and to the

deed or conveyance, shall become vested with all the rights, powers, trusts,
duties and obligations of the retiring Advancing Agent.

          (b) No appointment of a successor Advancing Agent shall become
effective unless each Rating Agency has confirmed in writing that the employment
of such successor would not adversely affect the rating on the Notes.

          (a) Pursuant to the Class A-1AR Note Purchase Agreement and subject to
compliance with the conditions set forth therein and herein, the Issuer (or the
Collateral Manager on behalf of the Issuer) may request, and the Holders of the

Class A 1AR Commitment of each Holder of Class A-1AR Notes. After the occurrence
of an Event of Default but prior to acceleration of the Notes, Class A-1AR Draws
may not be used to acquire additional Collateral Debt Securities or in
connection with a Special Amortization. Class A-1AR Draws may be made on any
Business Day from and including the Closing Date to but excluding the Commitment
Termination Time (the date of such Class A-1AR Draw, the "Class A-1AR Draw
Date"). Promptly following any request for a Class A-1AR Draw under the Class
A-1AR Note Purchase Agreement and in no event later than 5:00 pm on the Business
Day immediately prior to such Class A-1AR Draw, the Trustee shall determine the
LIBOR rate applicable to such Class A-1AR Draw and inform the Class A-1AR Note
Agent and the Issuer of such rate.

          (b) Draws may be made from time to time in accordance with the Class
A-1AR Note Purchase Agreement. The Issuer shall duly and punctually perform each
of its obligations under the Class A-1AR Note Purchase Agreement. The Issuer is
not required to borrow any amount under the Class A-1AR Notes on the Closing
Date or at any other time unless the applicable servicer or the Collateral
Manager, as applicable, has determined that a Delayed Funding Advance is
required under the related Underlying Instruments related to a Delayed Draw Term
Loan included in the Collateral Debt Securities and the amounts on deposit in
the Delayed Funding Obligations Account, if any, are insufficient to make such
Delayed Funding Advance.

          (c) On the Mandatory Class A-1AR Draw Date, the Issuer (or the
Collateral Manager on its behalf) will make a Class A-1AR Draw in an amount
equal to the Aggregate Class A-1AR Undrawn Amount, the proceeds of which shall
be deposited as follows: (i) the amount necessary to make the amount on deposit
in the Delayed Funding Obligations Account equal to the Total Unfunded Delayed
Funding Amount shall be deposited in the Delayed Funding Obligations Account,
and (ii) any remainder shall be deposited in the Collection Account as Principal
Proceeds. Immediately following such draw, the Class A-1AR Commitments shall
terminate.

          (d) To the extent that a Class A-1AR Draw (or a portion thereof) is
being made to fund Delayed Funding Amounts relating to Delayed Draw Term Loans,
the Trustee shall (at the direction of the Collateral Manager) upon receipt of
the proceeds of any Class A-1AR Draw, deposit such proceeds (or the applicable
portion thereof) into the Delayed Funding Obligations Account where such amounts
shall be applied in accordance with Section 10.6. To the extent that a Class
A-1AR Draw (or a portion thereof) is being made in connection with a Special
Amortization, the Trustee shall (at the direction of the Collateral Manager)
upon receipt of the proceeds of any Class A-1AR Draw, deposit such proceeds (or
the applicable portion thereof) into the Principal Collection Account where such
amounts shall be applied in accordance with Section 10.2.

          (e) The total of all Class A-1AR Commitments for all Holders of Class
A-1AR Notes shall not exceed the Maximum Class A-1AR Commitment. Notwithstanding
the foregoing, to the extent the Aggregate Outstanding Amount of the Class A-1
Notes is reduced in connection with a Mandatory Redemption, a Special
Amortization or a redemption in connection with a Rating Confirmation Failure,
the Class A-1AR Commitments will be reduced so that, after giving effect to such
reduction, the ratio (expressed as a percentage) of the


                                     -268-

<PAGE>

Maximum Class A-1AR Commitment to the Aggregate Outstanding Amount of the Class
A-1A Notes is equal to the Class A-1AR Proportion (and the Class A-1AR
Commitment related to each Class A-1AR Note will be reduced on a pro rata
basis). In connection with any Mandatory Redemption, to the extent that the
Class A-1AR Commitments are reduced to an amount less than the Minimum Class
A-1AR Commitment, a portion of the Interest Proceeds and/or Principal Proceeds
that are available for distribution shall be deposited into the Delayed Funding
Obligations Account until the Aggregate Class A-1AR Undrawn Amount equals the
Minimum Class A-1AR Commitment.

          Section 18.2 Class A-1AR Interest and Class A-1AR Commitment Fee.

          (a) With respect to any Payment Date, interest on the Class A-1AR
Notes will be payable in arrears in an amount equal to (A) the product of (i)
the Weighted Average Drawn Class A-1AR Note Portion during the related Interest
Accrual Period, (ii) the Class A-1AR Rate, and (iii) the actual number of days
elapsed in such Interest Accrual Period, divided by (B) 360; provided that
interest accrued in respect of amounts borrowed under the Class A-1AR Notes
during the period following the Determination Date through such Payment Date
will be payable (without penalty interest thereon) on the next succeeding
Payment Date. Interest on the Class A-1AR Notes will be payable from the date of
each Class A-1AR Draw under the Class A-1AR Notes, and accrued and unpaid
interest will be payable in arrears on each Payment Date. Interest will be
payable to the Holders of the Class A-1AR Notes, pro rata, based on their Class
A-1AR Interest Allocation.

          (b) The Class A-1AR Commitment Fee will accrue on the daily undrawn
amount of each Class A-1AR Commitment for each Interest Accrual Period at a rate
per annum equal to 0.22% (computed on the basis of a 360-day year and the actual
number of days elapsed). Among the Class A-1 Notes, the Class A-1AR Commitment
Fee will be payable in arrears on each Payment Date and will rank pari passu
with the payment of interest on the Class A-1A Notes and the Class A-1AR Notes.
Interest at the Class A-1AR Rate will accrue on any portion of the Class A-1AR
Commitment Fee that is not paid when due.

          Section 18.3 Prepayments of Class A-1AR Notes.

          (a) Prior to the Commitment Termination Time, the Class A-1AR Notes
may be prepaid (in whole or in part), at the option of the Issuer (at the
direction of the Collateral Manager) in accordance with the terms of the Class
A-1AR Note Purchase Agreement, without payment of a premium, on (i) any Payment
Date and prior to any payments on any other Class of Notes, from Principal
Proceeds to the extent Principal Proceeds are available for such application
pursuant to Section 11.1(a)(ii) and/or amounts on deposit in the Delayed Funding
Obligations Account or (ii) any Business Day other than a Payment Date, from
Principal Proceeds to the extent Principal Proceeds are available for such
application and/or amounts on deposit in the Delayed Funding Obligations
Account, but subject to the payment of Class A-1AR Breakage Costs. Any Class
A-1AR Breakage Costs will be paid in accordance with the Priority of Payments on
the Payment Date following the applicable Class A-1AR Prepayment Date.

          (b) The aggregate principal amount of any partial voluntary Class
A-1AR Prepayment, in respect of the Class A-1AR Notes (taken as a whole), will
be at least $500,000


                                     -269-

<PAGE>

(and integral multiples of $500 in excess thereof) or, if the aggregate
outstanding amount under the Class A-1AR Notes is less than $500,000, such
lesser amount. The Issuer shall make all Class A-1AR Prepayments pro rata based
on the Aggregate Outstanding Amount of the Class A-1AR Notes at the time such
prepayment is made. Subject to compliance with certain draw conditions specified
in the Class A-1AR Note Purchase Agreement and herein, all such prepaid amounts
may be re-borrowed until the Commitment Termination Time.

          (c) After the Mandatory Class A-1AR Draw Date, principal will be
payable to the Class A-1AR Notes pro rata with the Class A-1A Notes based on the
Class A-1A/A-1AR Pro Rata Allocation.

          (d) Prior to the Commitment Termination Time, the Aggregate Class
A-1AR Undrawn Amount must be an amount at least equal to the Minimum Class A-1AR
Commitment.

          Section 18.4 Class A-1AR Ratings Criteria.

          In accordance with the applicable provisions of the Class A-1AR Note
Purchase Agreement, at the time of its purchase of a Class A-1AR Note and prior
to the Commitment Termination Time, each Holder (including any transferee) of a
Class A-1AR Note must satisfy the Class A-1AR Ratings Criteria. Except in the
case of any "Committed Liquidity Provider" (as defined in the Class A-1AR Note
Purchase Agreement) which has funded the related Holder Subaccount in an amount
equal to its unfunded Class A-1AR Commitment, if any Holder of Class A-1AR Notes
at any time prior to the Commitment Termination Time fails to satisfy the Class
A-1AR Ratings Criteria, such Holder shall within five Business Days thereafter
deposit cash in a Holder Subaccount in an amount equal to the undrawn amount of
such Holder's Class A-1AR Commitment. If such Holder fails to fund a Holder
Subaccount as described in the preceding sentence, (i) the Issuer (or the
Collateral Manager on behalf of the Issuer) shall promptly replace such Holder
(at the cost of such Holder) with another entity that meets the Class A-1AR
Ratings Criteria (by requiring the replaced Holder to transfer all of its rights
and obligations in respect of the Class A-1AR Notes to the transferee entity)
and (ii) any payments of principal of, or interest on, any Class A-1AR Note held
by such Noteholder, and any payments of a Class A-1AR Commitment Fee otherwise
payable to such Noteholder, shall be remitted to a Holder Subaccount of such
Noteholder (each, a "Holder Subaccount") and held to secure the obligation of
such Noteholder. The purchase of Class A-1AR Notes (whether in connection with
the initial placement or in a subsequent transfer) by any purchaser who does not
satisfy the Class A-1AR Ratings Criteria set forth in clause (a) of the
definition thereof at the time of such purchase but who is then entitled to the
benefits of a Liquidity Facility described in clause (c) of such definition
shall not be permitted unless the Rating Agency Condition is satisfied with
respect thereto and such Liquidity Provider enters into an assignment and
acceptance agreement agreeing to undertake and be bound by the provisions of the
Class A-1AR Note Purchase Agreement applicable thereto.

          Section 18.5 Class A-1AR Holder Collateral Account.

          (a) The Trustee shall, prior to the Closing Date, establish a single,
segregated trust account which shall be designated as the "Class A-1AR Holder
Collateral Account," which account, together with any and all funds at any time
on deposit therein, or otherwise credited


                                     -270-

<PAGE>

thereto, shall be held in trust for the benefit of the Holders of the Class
A-1AR Notes and each Liquidity Provider (and, to the extent of amounts applied
in accordance with the Class A-1AR Note Purchase Agreement for such purpose, for
the benefit of the Holders of the Notes) and over which the Trustee shall have
exclusive control and the sole right of withdrawal. If at any time any Holder of
a Class A-1AR Note shall be required to deposit funds into the Class A-1AR
Holder Collateral Account pursuant to the terms of the Class A-1AR Note Purchase
Agreement, then (i) the Collateral Manager shall direct the Trustee to and the
Trustee shall create a Holder Subaccount and (ii) the Holder shall deposit all
required funds into such Holder Subaccount. All payments of principal of the
Class A-1AR Notes otherwise payable to such Holder shall be deposited in such
Holder Subaccount to the extent provided in the Class A-1AR Note Purchase
Agreement. The only permitted withdrawal from or application of funds credited
to a Holder Subaccount shall, notwithstanding the occurrence of any Event of
Default, be to satisfy such Holder's obligations under the Class A-1AR Note
Purchase Agreement, as specified in this Section 18.5 and to return such amounts
to such Holder in accordance with Section 18.5(d).

          (b) The deposit of funds into a Holder Subaccount pursuant to Section
18.5(a) by any Holder of a Class A-1AR Note shall not constitute a Class A-1AR
Draw by the Issuer and shall not constitute a Class A-1AR Draw or a utilization
of the Class A-1AR Commitment of such Holder, and the funds so deposited shall
not constitute principal outstanding under such Class A-1AR Note. However, from
and after the establishment of a Holder Subaccount with respect to any Holder of
Class A-1AR Notes until otherwise provided below, (i) the obligation of such
Holder to advance funds under its Class A-1AR Notes as part of any Class A-1AR
Draw under this Indenture and the Class A-1AR Note Purchase Agreement shall be
satisfied by the Collateral Manager withdrawing funds from such Holder
Subaccount in the amount of such Holder's share of such Class A-1AR Draw
(determined in accordance with the Class A-1AR Note Purchase Agreement), and
(ii) all payments of principal with respect to advances made by such Holder
under its Class A-1AR Notes (whether or not originally funded from such Holder
Subaccount) (and, in the case of any defaulting Holder, all payments of interest
thereon) shall be satisfied by the Collateral Manager depositing or causing the
deposit of the related funds into such Holder Subaccount, with notice of such
deposit to the Class A-1AR Note Agent. The Collateral Manager shall have full
power and authority to withdraw funds (with prior notice of any such withdrawal
to the Class A-1AR Note Agent) from each such Holder Subaccount at the time of,
and in connection with, the making of any such Class A-1AR Draw and to deposit
funds (with notice of any such deposit to the Class A-1AR Note Agent) into each
such Holder Subaccount, all in accordance with the terms of and for the purposes
set forth in this Indenture and the Class A-1AR Note Purchase Agreement.

          (c) If at any time the amount of funds on deposit in the Holder
Subaccount relating to any Holder of Class A-1AR Notes, net of any earnings in
respect of Class A-1AR Eligible Investments, exceeds the undrawn amount of the
Class A-1AR Commitment of such Holder (whether due to a reduction in the Class
A-1AR Commitment or otherwise), then the Collateral Manager on behalf of the
Issuer shall instruct the Trustee to remit to such Holder a specified portion of
such funds then held in the related Holder Subaccount in an amount equal to such
excess.

          (d) If at any time a Holder of Class A-1AR Notes is no longer required
to deposit or maintain funds in the Class A-1AR Holder Collateral Account
pursuant to the terms of


                                     -271-

<PAGE>

the Class A-1AR Note Purchase Agreement to which such Holder is a party, then
the Collateral Manager shall notify the Trustee of such fact and direct the
Trustee to remit all funds (including, for the avoidance of doubt, earnings in
respect of Class A-1AR Eligible Investments) then held in the relevant Holder
Subaccount (after giving effect to any Class A-1AR Draw in respect of such Class
A-1AR Notes to be made on such date) to such Holder (with notice thereof to the
Class A-1AR Note Agent), and thereafter all payments of principal and interest
with respect to advances made by such Holder shall be paid directly to such
Holder in accordance with the terms of this Indenture and the Class A-1AR Note
Purchase Agreement.

          (e) The Trustee agrees to give the Issuer, the Collateral Manager and
the related Holder immediate notice if it becomes aware that the Class A-1AR
Holder Collateral Account, any Holder Subaccount or any funds on deposit
therein, or otherwise to the credit of the Class A-1AR Holder Collateral Account
or any Holder Subaccount, shall become subject to any writ, order, judgment,
warrant of attachment, execution or similar process. Except to the extent
specifically set forth herein, the Issuer shall not have any legal, equitable or
beneficial interest in the Class A-1AR Holder Collateral Account. The Class
A-1AR Holder Collateral Account shall remain at all times with the Corporate
Trust Office or a financial institution having a long term debt rating by each
Rating Agency at least equal to "A" or "A2," as applicable, and a short term
debt rating at least equal to "A-1" or "P-1," as applicable.

          (f) For so long as any amounts are on deposit in a Holder Subaccount,
the Trustee shall, at the written direction of the related Class A-1AR
Noteholder (which may be in the form of standing instructions), invest and
reinvest such funds in investments which satisfy the definition of the term
"Eligible Investments" but which mature not later than the day following the
date of acquisition thereof (collectively, "Class A-1AR Eligible Investments").
Investment earnings received during each Due Period in respect of Eligible
Investments in the Holder Subaccount of a Holder of Class A-1AR Notes will (so
long as such Holder is not a defaulting Holder) be paid to such Holder on the
related Payment Date. In the absence of such instructions, such funds will
remain uninvested.
