PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York 10019

Ladies and Gentlemen:

            CABCO Trust for Florida P & L First Mortgage Bonds, a common law
trust created under the laws of the state of New York (the "Trust"), proposes to
sell to PaineWebber Incorporated (the "Underwriter"), pursuant to this agreement
(this "Agreement"), 1,000,000 Trust Certificates, principal amount $25 per
certificate (the "Certificates"), to be issued pursuant to the Amended and
Restated Trust Agreement to be dated as of the Closing Date (as defined below),
including the Standard Terms and Provisions of Series Trust Deposit Agreement
incorporated therein by reference (the "Trust Agreement") between Corporate
Asset Backed Corporation (the "Depositor") and United States Trust Company of
New York, as trustee (the "Trustee"). The Certificates will represent in the
aggregate the entire beneficial ownership interest in the Trust, whose sole
asset consists of $25,000,000 of 7.05% First Mortgage Bonds due 2026 issued by
Florida Power & Light Company exclusive of interest accrued thereon from and
including June 1, 1999, to but excluding the Closing Date (exclusive of such
interest, the "Underlying Securities"). Pursuant to an assignment agreement
dated as of the Closing Date (the "Assignment Agreement") between the
Underwriter and the Depositor, the Underwriter will convey the Underlying
Securities to the Depositor. Pursuant to the Trust Agreement and a
Cross-Receipt, the Depositor will convey the Underlying Securities to the
Trustee. The Certificates are described more fully in the Registration Statement
(as hereinafter defined). This is to confirm the arrangements with respect to
the Underwriter's purchase of the Certificates.

            The Assignment Agreement, the Trust Agreement and this Agreement are
collectively referred to herein as the "Transaction Documents."

            The Depositor has filed with the Securities and Exchange Commission
(the "Commission") a registration statement on Form S-3 (No. 33-91744) for the
registration of the
<PAGE>   2
Certificates under the Securities Act of 1933 (the "1933 Act"), which
registration statement has become effective and copies of which, as amended to
the date hereof, have been delivered to the Underwriter. The Depositor proposes
to file with the Commission pursuant to Rule 424(b)(5) under the rules and
regulations of the Commission under the Act (the "1933 Act Regulations") a
prospectus supplement to be dated June 7, 1999 (the "Prospectus Supplement") to
the prospectus (the "Base Prospectus") dated March 18, 1999 included in such
registration statement, relating to the Certificates and the method of
distribution thereof. Such registration statement on Form S-3, including
exhibits thereto, as amended as of the date hereof, is hereinafter called the
"Registration Statement"; and such prospectus, as supplemented by the Prospectus
Supplement, is hereinafter called the "Prospectus."

            SECTION 1.  Representations and Warranties.

            (a) The Depositor represents and warrants to each of the Trustee and
the Underwriter as follows:

                  (i) The Registration Statement, as amended as of the effective
      date thereof (the "Effective Date"), and the Prospectus, as of the date
      thereof, complied in all material respects with the requirements of the
      1933 Act and the 1933 Act Regulations. The Registration Statement, as of
      the Effective Date, did not contain an untrue statement of a material fact
      or omit to state any material fact required to be stated therein or
      necessary to make the statements therein not misleading. The Prospectus,
      as of the date thereof, did not, and as of the Closing Date will not,
      contain any untrue statement of a material fact or omit to state a
      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading;
      provided, however, that the representations and warranties in this
      subsection shall not apply to statements in or omissions from the
      Registration Statement or Prospectus made in reliance upon and in
      conformity with information furnished to the Depositor in writing by the
      Underwriter expressly for use in the Registration Statement or Prospectus.
      The Depositor and the Underwriter hereby acknowledge that only the
      statements set forth in the paragraph immediately preceding the final
      paragraph of page 2 of the Base Prospectus, the first sentence of the
      final paragraph of page 2 of the Base Prospectus, the final paragraph of
      the cover of the Prospectus Supplement and under the caption
      "Underwriting" in the Prospectus Supplement constitute statements made in
      reliance upon and in conformity with information furnished to the
      Depositor in writing by the Underwriter expressly for use in the
      Registration Statement or Prospectus.

                  (ii) Since the respective dates as of which information is
      given in the Registration Statement and Prospectus, except as otherwise
      stated therein, (A) there has been no material adverse change in the
      condition, financial or otherwise, or in the earnings, business affairs or
      business prospects of the Depositor, whether or not arising in the
      ordinary course of business, and (B) there have been no transactions
      entered into by the Depositor, other than those in the ordinary course of
      business, which are material with respect to the Depositor.


                                       -2-
<PAGE>   3
                  (iii) The Depositor has been duly organized and is validly
      existing as a corporation in good standing under the laws of the State of
      Delaware with corporate power and authority to own, lease and operate its
      properties and to conduct its business, as now conducted by it, and to
      enter into and perform its obligations under the Transaction Documents to
      which it is a party.

                  (iv) The Depositor is not in violation of its charter or in
      default in the performance or observance of any material obligation,
      agreement, covenant or condition contained in any contract, indenture,
      mortgage, loan agreement, note, lease or other instrument to which the
      Depositor is a party, or to which any of the property or assets of the
      Depositor may be subject, or by which it or any of them may be bound; and
      the execution, delivery and performance of the Transaction Documents to
      which it is a party and the consummation of the transactions contemplated
      therein and compliance by the Depositor with its obligations thereunder
      have been duly authorized by all necessary corporate action and will not
      conflict with or constitute a breach of, or default under, or result in
      the creation or imposition of any lien, charge or encumbrance upon any
      property or assets of the Depositor pursuant to, any material contract,
      indenture, mortgage, loan agreement, note, lease or other instrument to
      which the Depositor is a party or by which it or any of them may be bound,
      or to which any of the property or assets of the Depositor is subject, nor
      will such action result in any violation of the provisions of the charter
      or by-laws of the Depositor or any applicable law, administrative
      regulation or administrative or court decree.

                  (v) There is no action, suit or proceeding before or by any
      court or governmental agency or body, domestic or foreign, now pending or,
      to the knowledge of the Depositor, threatened against or affecting the
      Depositor, which is required to be disclosed in the Registration Statement
      (other than as disclosed therein), or which might result in any material
      adverse change in the condition, financial or otherwise, or in the
      earnings, business affairs or business prospects of the Depositor, or
      which might materially and adversely affect the properties or assets
      thereof or which might materially and adversely affect the consummation of
      the transactions contemplated by the Transaction Documents to which it is
      a party; all pending legal or governmental proceedings to which the
      Depositor is a party or of which its property or assets is the subject
      which are not described in the Registration Statement, including ordinary
      routine litigation incidental to the business, are, considered in the
      aggregate, not material; and there are no contracts or documents of the
      Depositor which are required to be filed as exhibits to the Registration
      Statement by the 1933 Act or by the 1933 Act Regulations which have not
      been so filed.

                  (vi) No authorization, approval or consent of any court or
      governmental authority or agency is necessary in connection with the
      offering, issuance or sale of the Certificates, except such as have been,
      or as of the Closing Date will have been, obtained or such as may
      otherwise be required under applicable state securities laws in connection
      with the purchase and offer and sale of the Certificates by the
      Underwriter.


                                       -3-
<PAGE>   4
                  (vii) The Depositor possesses all material licenses,
      certificates, authorities or permits issued by the appropriate state,
      federal or foreign regulatory agencies or bodies necessary to conduct the
      business now operated by it, and the Depositor has not received any notice
      of proceedings relating to the revocation or modification of any such
      license, certificate, authority or permit which, singly or in the
      aggregate, if the subject of an unfavorable decision, ruling or finding,
      would materially and adversely affect the condition, financial or
      otherwise, or the earnings, business affairs or business prospects of the
      Depositor.

                  (viii) Each of the Transaction Documents to which it is a
      party has been duly authorized, executed and delivered by the Depositor
      and constitutes a legal, valid and binding agreement enforceable against
      the Depositor in accordance with its terms, except as enforceability may
      be limited by (A) bankruptcy, insolvency, reorganization, receivership,
      moratorium or other similar laws affecting the enforcement of the rights
      of creditors generally, (B) general principles of equity, whether
      enforcement is sought in a proceeding in equity or at law, and (C) public
      policy considerations underlying the securities laws, to the extent that
      such public policy considerations limit the enforceability of the
      provisions of such Transaction Documents that purport to provide
      indemnification from securities law liabilities.

                  (ix) At the time of the execution and delivery of the Trust
      Agreement, the Depositor (A) will have good and marketable title to the
      Bonds being transferred by it to the Trustee pursuant thereto, free and
      clear of any lien, mortgage, pledge, charge, encumbrance, adverse claim or
      other security interest (collectively "Liens"), (B) will not have assigned
      to any person any of its right, title or interest in such Bonds or in the
      Trust Agreement and (C) will have the power and authority to transfer such
      Bonds to the Trustee, and upon execution and delivery of the Trust
      Agreement, the Trustee will have acquired ownership of all of the
      Depositor's right, title and interest in and to the related Bonds, and
      upon delivery to the Underwriter of the Certificates pursuant to this
      Agreement, the Underwriter will have good and marketable title to the
      Certificates, in each case free of Liens.

                  (x) The Certificates and the Trust Agreement will each conform
      in all material respects to the descriptions thereof contained in the
      Prospectus, and the Certificates, when duly and validly authorized,
      executed, authenticated and delivered in accordance with the Trust
      Agreement and paid for as provided herein, will be entitled to the
      benefits of the Trust Agreement.

                  (xi) The Trust created by the Trust Agreement will not be
      required to be registered as an investment company under the Investment
      Company Act of 1940, as amended (the "1940 Act"), and, as of the Closing
      Date, the Trust Agreement shall be duly qualified as an indenture under
      the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").


                                       -4-
<PAGE>   5
                  (xii) At the Closing Date, each of Moody's Investors Service,
      Inc. and Standard & Poor's Ratings Group shall have assigned an investment
      grade rating to the Certificates.

                  (xiii) Any taxes, fees and other governmental charges in
      connection with the execution, delivery and issuance of the Transaction
      Documents to which it is a party and the Certificates have been paid or
      will be paid at or prior to the Closing Date.

                  (xiv) The sale of the Bonds to the Trustee on the Closing Date
      will be treated by the Depositor for financial accounting and reporting
      purposes as a sale of assets and not as a pledge of assets to secure debt.

            (b) Any certificate signed by any officer of the Depositor and
delivered to the Trustee, the Underwriter or their counsel shall be deemed a
representation and warranty by the Depositor to the Trustee and the Underwriter
as to the matters covered thereby.

            SECTION 2.  Purchase and Sale.

            Subject to the terms and conditions herein set forth and in reliance
upon the representations and warranties herein contained, the Trust agrees to
sell to the Underwriter, and the Underwriter agrees to purchase from the Trust
1,000,000 Certificates at a purchase price of $24,212,500.

            SECTION 3.  Delivery and Payment.

            Payment of the purchase price for, and delivery of, the Certificates
to be purchased by the Underwriter shall be made at the office of PaineWebber
Incorporated, 1285 Avenue of the Americas, New York, New York 10019, or at such
other place as shall be agreed upon by the Underwriter and the Trust, at 10:00
a.m. New York City time, on June 14, 1999, which date and time may be postponed
by agreement between you and the Trust (such time and date of payment and
delivery being herein called the "Closing Date"). Payment shall be made to the
Trust or its order at the Trust's option, by (i) appropriate notation of an
inter company transfer between affiliates of PaineWebber Group, Inc. or (ii) in
immediately available Federal funds wired to such bank as may be designated by
the Trust, against delivery of the Certificates. The Certificates shall be in
such denominations and registered in such names as you may request in writing at
least two business days before the Closing Date. The Certificates will be made
available for examination and packaging by you not later than 10:00 a.m. on the
last business day prior to the Closing Date.

            SECTION 4. Covenants of the Depositor. The Depositor covenants with
the Trustee and the Underwriter as follows:

            (a) The Depositor will give the Trustee and the Underwriter notice
of its intention to file or prepare any amendment to the Registration Statement
or any amendment or supplement to the Prospectus (including any revised
prospectus which the Depositor proposes for use by the Underwriter in connection
with the offering of the Certificates which differs from the prospectus on file
at the Commission at the time the Registration Statement becomes effective,
whether or not such revised prospectus is required to be filed pursuant to Rule
424(b) of the 1933 Act Regulations), will furnish the Underwriter with copies of
any such amendment or supplement a reasonable amount of time prior to such
proposed filing or use, as the case may be, and will not file any such amendment
or supplement or use any such prospectus to which the Underwriter shall
reasonably object.

            (b) The Depositor will cause the Prospectus to be transmitted to the
Commission for filing pursuant to Rule 424(b)(5) under the 1933 Act by means
reasonably calculated to result in filing with the Commission pursuant to said
rule.

            (c) The Depositor will deliver to the Underwriter as many signed
copies of the Registration Statement as originally filed and of each amendment
thereto (including exhibits filed therewith or incorporated by reference
therein) as the Underwriter may reasonably request and will also deliver to the
Underwriter a conformed copy of the Registration Statement as originally filed
and of each amendment thereto (without exhibits).

            (d) The Depositor will furnish to the Underwriter, from time to time
during the period when the Prospectus is required to be delivered under the 1933
Act or the Securities Exchange Act of 1934 (the "1934 Act"), such number of
copies of the Prospectus (as amended or supplemented) as the Underwriter may
reasonably request for the purposes contemplated by the 1933 Act or the 1934 Act
or the respective applicable rules and regulations of the Commission thereunder.

            (e) If, during the period after the first date of the public
offering of the Certificates in which a prospectus relating to the Certificates
is required to be delivered under the 1933 Act, any event shall occur as a
result of which it is necessary, in the opinion of counsel for the Depositor, to
amend or supplement the Prospectus in order to make the Prospectus not
misleading in the light of the circumstances existing at the time it is
delivered to a purchaser, the Depositor will forthwith amend or supplement the
Prospectus (in form and substance satisfactory to counsel for the Depositor) so
that, as so amended or supplemented, the Prospectus will not include an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances existing at
the time it is delivered to a purchaser, not misleading, and the Depositor will
furnish to the Trustee and the Underwriter a reasonable number of copies of such
amendment or supplement.

            (f) The Depositor will endeavor to arrange for the qualification of
the Certificates for sale under the applicable securities laws of such states
and other jurisdictions of the United States


                                       -6-

as the Underwriter may designate; provided, however, that the Depositor shall
not be obligated to qualify as a foreign corporation in any jurisdiction in
which it is not so qualified. In each jurisdiction in which the Certificates
have been so qualified, the Depositor will file such statements and reports as
may be required by the laws of such jurisdiction to continue such qualification
in effect for a period of not less than one year from the effective date of the
Registration Statement.

            (g) If the transactions contemplated by this Agreement are
consummated, the Depositor will pay or cause to be paid all expenses incident to
the performance of the obligations of the Depositor under this Agreement.

            (h) If, during the period after the Closing Date in which a
prospectus relating to the Certificates is required to be delivered under the
1933 Act, the Depositor receives notice that a stop order suspending the
effectiveness of the Registration Statement or preventing the offer and sale of
the Certificates is in effect, the Depositor will immediately advise the
Underwriter and the Trustee of the issuance of such stop order. The Depositor
will make every reasonable effort to prevent the issuance of any stop order and,
if any stop order is issued, to obtain the lifting thereof at the earliest
possible moment.

            SECTION 5. Conditions of Underwriter's Obligations. The
Underwriter's obligation to purchase the Certificates shall be subject to the
following conditions:

            (a) No stop order suspending the effectiveness of the Registration
Statement shall be in effect, and no proceedings for that purpose shall be
pending or, to the Depositor's knowledge, threatened by the Commission.

            (b) On the Closing Date, counsel for the Underwriter shall have been
furnished with such other documents and opinions as they may reasonably require
for the purpose of enabling them to pass upon the issuance and sale of the
Certificates as herein contemplated and related proceedings, or in order to
evidence the accuracy of any of the representations or warranties, or the
fulfillment of any of the conditions, herein contained; and all proceedings
taken by the Trust in connection with the issuance and sale of the Certificates
as herein contemplated shall be satisfactory in form and substance to the
Underwriter and counsel for the Underwriter.

            If any condition specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by the Underwriter by notice to the Trust at any time at or prior to the Closing
Date, and such termination shall be without liability of any party to any other
party.

            SECTION 6.  Indemnification.

            (a) The Depositor agrees to indemnify and hold harmless the
Underwriter and each person, if any, who controls the Underwriter, within the
meaning of Section 15 of the 1933 Act, as follows:

                  (i) against any and all loss, liability, claim, damage and
      expense whatsoever, as incurred, arising out of any untrue statement or
      alleged untrue statement of a material fact contained in the Registration
      Statement (or any amendment thereto), including the information deemed to
      be part of the Registration Statement pursuant to Rule 430A(b) of the 1933
      Act Regulations, if applicable, or the omission or alleged omission
      therefrom of a material fact required to be stated therein or necessary to
      make the statements therein not misleading or arising out of any untrue
      statement or alleged untrue statement of a material fact contained in the
      Prospectus (or any amendment or supplement thereto) or the omission or
      alleged omission therefrom of a material fact necessary in order to make
      the statements therein, in the light of the circumstances under which they
      were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
      expense whatsoever, as incurred, to the extent of the aggregate amount
      paid in settlement of any litigation, or any investigation or proceeding
      by any governmental agency or body, commenced or threatened, or of any
      claim whatsoever based upon any such untrue statement or omission, or any
      such alleged untrue statement or omission, if such settlement is effected
      with the written consent of the Depositor; and

                  (iii) against any and all expense whatsoever, as incurred
      (including the fees and disbursements of counsel chosen by the
      Underwriter), reasonably incurred in investigating, preparing or defending
      against any litigation, or any investigation or proceeding by any
      governmental agency or body, commenced or threatened, or any claim
      whatsoever based upon any such untrue statement or omission, or any such
      alleged untrue statement or omission, to the extent that any such expense
      is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Depositor by
the Underwriter expressly for use in the Registration Statement (or any
amendment thereto) or Prospectus (or any amendment or supplement thereto). The
Depositor and the Underwriter hereby acknowledge that only the statements set
forth in the paragraph immediately preceding the final paragraph of page 2 of
the Base Prospectus, the first sentence of the final paragraph of page 2 of the
Base Prospectus, the final paragraph of the cover of the Prospectus Supplement
and under the caption "Underwriting" in the Prospectus Supplement constitute
statements made in reliance upon and in conformity with information furnished to
the Depositor in writing by the Underwriter expressly for use in the
Registration Statement or Prospectus.

<PAGE>   9
            (b) The Underwriter agrees to indemnify and hold harmless the
Depositor, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Depositor within the
meaning of Section 15 of the 1933 Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto) or the Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Depositor by the Underwriter expressly for use in the
Registration Statement (or any amendment thereto) or the Prospectus (or any
amendment or supplement thereto). The Depositor and the Underwriter hereby
acknowledge that only the statements set forth in the paragraph immediately
preceding the final paragraph of page 2 of the Base Prospectus, the first
sentence of the final paragraph of page 2 of the Base Prospectus, the final
paragraph of the cover of the Prospectus Supplement and under the caption
"Underwriting" in the Prospectus Supplement constitute statements made in
reliance upon and in conformity with information furnished to the Depositor in
writing by the Underwriter expressly for use in the Registration Statement or
Prospectus.

            (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability which it may have otherwise than on account of this indemnity
agreement. An indemnifying party may participate at its own expense in the
defense of any such action. In no event shall the indemnifying parties be liable
for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.

            SECTION 7. Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 hereof is for any reason held to be unenforceable by the indemnified
parties although applicable in accordance with its terms, the Depositor and the
Underwriter shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Depositor and the Underwriter, as incurred, in such proportion
as is appropriate to reflect not only the relative benefits received by the
Depositor on the one hand and the Underwriter on the other from the offering of
the Certificates but also the relative fault of the Depositor on the one hand
and the Underwriter on the other in connection with the statements or omissions
which resulted on such losses, claims, damages or liabilities, as well as any
other relevant equitable considerations. The relative fault of the Depositor on
the one hand and of the Underwriter on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact relates to information supplied by the Depositor or by the
Underwriter, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission; provided,
however, that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty


                                       -9-
<PAGE>   10
of such fraudulent misrepresentation. For purposes of this Section, each person,
if any, who controls the Underwriter within the meaning of Section 15 of the
1933 Act shall have the same rights to contribution as the Underwriter, and each
director of the Depositor, each officer of the Depositor who signed the
Registration Statement, and each person, if any, who controls the Depositor
within the meaning of Section 14 of the 1933 Act shall have the same rights to
contribution as the Depositor.

            SECTION 8. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers submitted pursuant hereto,
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Underwriter or controlling person, or
by or on behalf of the Trust, and shall survive delivery of the Certificates to
the Underwriter.

            SECTION 9. Termination of Agreement.

            (a) If the Trust Agreement is not executed by the Closing Date, this
Agreement shall terminate within 15 days after the Closing Date, and such
termination shall be without liability of any party to any other party.

            (b) The Underwriter may terminate this Agreement, by notice to the
Trust and the Depositor, at any time at or prior to the Closing Date (i) if
there has been, since the date of this Agreement or since the date as of which
information is given in the Registration Statement, any material adverse change
in the condition, financial or otherwise, or in the earnings, business affairs
or business prospects of the Trust and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
if there has occurred any material adverse change in the financial markets in
the United States or elsewhere or any outbreak of hostilities or escalation
thereof or other calamity or crisis the effect of which is such as to make it,
in the judgment of the Underwriter, impracticable to market the Certificates or
to enforce contracts for the sale of the Certificates, or (iii) if trading
generally on either the American Stock Exchange or the New York Stock Exchange
has been suspended, or minimum or maximum prices for trading have been fixed, or
maximum ranges for prices for securities have been required, by either of said
Exchanges or by order of the Commission or any other governmental authority, or
if a banking moratorium has been declared by either Federal or New York
authorities.


            (c) If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party.

            SECTION 10. Notices. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication. Notices to the
Underwriter shall be directed to PaineWebber Incorporated at 1285 Avenue of the
Americas, New York, New York 10019, Attention: Jonathan Gottlieb; notices to the
Trust shall be directed to the Trustee at United States Trust Company of New
York, 114 West 47th Street, New York, New York 10036-1532, Attention: Thomas

Incorporated at 1285 Avenue of the Americas, New York, New York 10019,
Attention: Jonathan Gottlieb; or, as to any party, such other address as may
hereafter be furnished by such party to the other in writing.

            SECTION 11. Parties. This Agreement shall inure to the benefit of
and be binding upon the Underwriter, the Depositor and the Trust and their
respective successors. In addition, this Agreement shall inure to the benefit of
any third party named herein as a third party beneficiary and only to the extent
provided herein. Nothing expressed or mentioned in this Agreement is intended or
shall be construed to give any person, firm or corporation, other than the
Underwriter and the Trust and their respective successors and the controlling
persons and officers and directors referred to in Section 5 and their heirs and
legal representatives, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision herein contained. This Agreement and
all conditions and provisions hereof are intended to be for the sole and
exclusive benefit of the Underwriter and the Trust and their respective
successors, and said controlling persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm or
corporation. No purchaser of Certificates from the Underwriter shall be deemed
to be a successor by reason merely of such purchase.

            SECTION 12. Governing Law; and Time. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
applicable to agreements made and to be performed in said State. Specified times
of day refer to New York City time.

                  OF BONDS; FORM OF CERTIFICATES; EXECUTION AND
               DELIVERY, SURRENDER AND REDEMPTION OF CERTIFICATES

      Section 2.01. Creation of Trust; Delivery and Custody of Bonds; Execution
and Delivery of Certificates in Respect Thereof. The Trust shall be established
by the Depositor by execution and delivery of the Series Trust Agreement and the
deposit of the Bonds pursuant thereto. The sole asset of the Trust shall be the
Bonds deposited by the Depositor and any other related property specified in the
Series Trust Agreement. The Certificates shall evidence fractional interests in
designated portions of the assets of the Trust. The income received by, and the
assets of, the Trust shall be distributed solely in accordance with this
Agreement. The Depositor shall, by book-entry credit or otherwise, irrevocably
deliver the Bonds to the Trustee and, concurrently therewith, the Trustee shall,
in accordance with the provisions of this Agreement, execute and deliver to the
Depositor, or such Person or Persons as the Depositor may designate by written
instruction, the classes of Certificates identified in the Series Trust
Agreement, evidencing the aggregate amount, in Authorized Denominations, of the
Bonds so delivered to the Trustee. The Depositor shall also, in connection with
the Series Trust Agreement, enter into a separate agreement with the Trustee,
satisfactory to the Trustee, providing for the payment of the charges and
expenses of the Trustee in respect of such Certificates.

      The Trustee shall accept the Bonds so delivered as trustee for the Holders
of the Certificates, which shall be delivered hereunder to evidence the
interests of the Holders in the Bonds, and shall hold the Bonds as provided
hereunder. The Bonds shall be deposited by Book-Entry Credit in an account
maintained on behalf of the Trustee at DTC, unless the Series Trust Agreement
specifies that the Trustee shall hold the Bonds (i) in a special trust account
created by separate recordation on its books, separate from all other assets of
the Trustee, or (ii) in some other manner. Separate subaccounts of any such
special trust account shall be established for each series of Certificates.

      The Trustee shall hold all the Bonds delivered to it pursuant to this
Agreement in trust for the Holders, identified and held separate and apart from
the general assets of the Trustee. The account of the Trustee in which the Bonds
are held shall not contain any property of the Trustee in its individual
capacity and shall contain only property held by the Trustee as fiduciary. The
Trustee agrees that it does not have the authority to assign, transfer,
encumber, pledge, sell, set-off or otherwise dispose of any of the Bonds or any
interests therein except as provided hereunder or as required by law.

      The Trustee acknowledges that it is not the beneficial owner of the Bonds
and that it holds the Bonds solely as trustee for the Holders pursuant to this
Agreement. Interest and principal payments


                                       B-7
<PAGE>   18
on the Bonds held in the trust account will not be subject to any right, charge,
security interest, lien or claim of any kind in favor of the Trustee, the
Depositor or any Person claiming through either of them.

      The representations and covenants contained in the Officer's Certificate
of the Trustee delivered in connection with the issuance of the Certificates
shall be deemed to be incorporated by reference herein, as fully as if set forth
in full herein.

      A reasonable time prior to the delivery of Bonds to the Trustee, the
Depositor shall furnish the Trustee with written instructions as to the name in
which the Certificates evidencing interests in such Bonds shall initially be
registered, the denominations in which such Certificates shall initially be
delivered, the Persons and addresses to whom such Certificates are to be
delivered and such other information as may be requested by the Trustee in
connection with the execution and delivery of such Certificates. Each class of
Certificates shall evidence the ownership by the Holders thereof of Interest,
Principal, or Callable Principal (or portions thereof), as the case may be, on
the Bonds, less any Retained Amount, to the extent required by the terms of such
class of Certificates.

      Bonds underlying Certificates which are not held by book-entry credit at
an account maintained on behalf of the Trustee at DTC shall be held by the
Trustee at its Designated Office in New York City or at such other place or
places as the Trustee shall determine.

      Section 2.02. Form of Certificates. Certificates shall be issued in
registered form only and shall be typewritten or printed on safety paper. The
classes of Certificates to be issued hereunder shall be identified in the Series
Trust Agreement and shall be substantially in the forms set forth in Exhibit C
thereto, in each case with appropriate insertions, modifications and omissions,
as therein and herein so provided. Certificates shall be executed by the Trustee
by the manual signature of a duly authorized signatory of the Trustee. No
Certificate shall be entitled to any benefits under this Agreement or be valid
or obligatory for any purpose, unless it shall have been executed manually by
the Trustee by the signature of a duly authorized signatory. The Trustee shall
record in the Certificate Register each Certificate so signed and delivered as
herein provided.

      The Authorized Denominations for each class of Certificates shall be the
dollar amount, and greater multiples thereof (or of such other dollar amount
specified in the Series Trust Agreement), set forth in the Series Trust
Agreement.

      Certificates may be endorsed with or have incorporated in the text thereof
such legends or recitals not inconsistent with the provisions of this Agreement
as may be required by the Trustee or required to comply with any applicable law
or any regulation thereunder.

      Section 2.03. Registration and Registration of Transfer and Exchange of
Certificates. The Trustee shall keep at its Designated Office in New York City a
register (the register maintained in such office being herein sometimes referred
to as the "Certificate Register") in which, subject to such reasonable
regulations as it may prescribe, the Trustee shall provide for the registration
of Certificates and for the registration of transfers or exchanges of
Certificates.


                                       B-8
<PAGE>   19
      Upon surrender for registration of transfer of any Certificate at the
Trustee's Designated Office in New York City, the Trustee shall execute and
deliver, in the name of the designated transferee or transferees, one or more
Certificates of the same class and series, of any Authorized Denominations and
of a like aggregate amount.

      At the option of the Holder, Certificates may be exchanged for other
Certificates of the same class and series, of any Authorized Denominations and
of a like aggregate amount, upon surrender of the Certificates to be exchanged
at the Trustee's Designated Office in New York City. Whenever any Certificates
are so surrendered for exchange, the Trustee shall execute and deliver the
Certificates which the Holder making the exchange is entitled to receive.

      All Certificates issued upon any registration of transfer or exchange of
Certificates shall evidence, to the extent indicated thereby, Interest,
Principal and/or Callable Principal (or portions thereof), as the case may be,
of Bonds held by the Trustee hereunder and shall be entitled to the same
benefits under this Agreement as the Certificates surrendered upon such
registration of transfer or exchange.

      Every Certificate presented for registration of transfer or for exchange
shall (if so required by the Trustee) be duly endorsed by, or be accompanied by
a written instrument of transfer in form satisfactory to the Trustee and duly
executed by, the Holder thereof or such Holder's attorney duly authorized in
writing.

      Section 2.04. Limitations on Execution and Delivery, Surrender and
Registration of Transfer and Exchange of Certificates. As a condition precedent
to the execution and delivery, surrender or registration of transfer or exchange
of any Certificate, the Trustee may require payment, by the Holder requesting
such action, of the then applicable service charge of the Trustee and of a sum
sufficient for reimbursement of any tax or other governmental charge with
respect thereto, may require the production of proof reasonably satisfactory to
it as to the Holder's residence and identity and genuineness of any signature,
may require the Holder to execute certificates and to make such representations
and assurances as the Trustee may reasonably deem necessary or proper, and may
also require compliance with such regulations, if any, as the Trustee may
reasonably establish consistent with the provisions of this Agreement.

      The surrender or registration of transfer or exchange of Certificates may
be suspended if any such suspension is deemed necessary or advisable by the
Trustee at any time or from time to time because of any requirement of law or of
any government or governmental body or commission, or under any provision of
this Agreement, or for any other reason which makes such surrender or
registration of transfer or exchange impracticable.

      Section 2.05. Mutilated, Destroyed, Lost or Stolen Certificates. In case
any Certificate shall be mutilated, the Trustee in its discretion may execute
and deliver a Certificate of the same series, of like form and tenor, and in the
same denomination and bearing a number not contemporaneously outstanding, in
exchange and substitution for such mutilated Certificate. In case any
Certificate shall


                                       B-9
<PAGE>   20
be destroyed, lost or stolen, the Trustee may execute and deliver a Certificate
of the same series, of like form and tenor, and in the same denomination and
bearing a number not contemporaneously outstanding, in lieu of and in
substitution for such destroyed, lost or stolen Certificate, only upon (i) the
filing by the Holder thereof with the Trustee of evidence satisfactory to the
Trustee of the destruction, loss or theft of such Certificate and of the
authenticity of such Holder's ownership thereof, and (ii) the furnishing to the
Trustee of reasonable indemnification satisfactory to it. All expenses and
charges associated with such indemnity and with the preparation, execution and
delivery of a new Certificate shall be borne by the Holder of the Certificate
mutilated, destroyed, lost or stolen.

      Section 2.06. Persons Deemed Owners. Prior to due presentment of a
Certificate for registration of transfer, the Trustee and any agent of the
Trustee may treat the Person in whose name such Certificate is registered as the
owner of such Certificate for the purpose of receiving payment of such
Certificate and for all other purposes whatsoever, whether or not such
Certificate be overdue, and neither the Trustee nor any agent of the Trustee
shall be affected by notice to the contrary.

      Section 2.07. Cancellation and Destruction of Surrendered Certificates.
All Certificates surrendered to the Trustee shall be canceled by the Trustee.
The Trustee is authorized to destroy such Certificates so cancelled.

      Section 2.08. Book-Entry. (i) At the election of the Depositor, the Series
Trust Agreement may provide that (1) all Certificates of a series are to be held
in DTC's book-entry only system, (2) all Certificates of a series are to be
issued in definitive physical form, or (3) the Certificates (or any part
thereof) are to be issued or held in such other form as is specified in the
Series Trust Agreement.

      (ii) Notwithstanding Section 4.01 hereof, when the registered Holder of
any or all of the Certificates is DTC, such Certificates shall be registered in
the name of Cede & Co., as nominee for DTC, and payment in respect of any
Interest, Principal or Callable Principal represented by any Certificate shall
be made on or after the corresponding Interest Payment Dates, in the case of the
payment of Interest, and on or after the corresponding stated maturity date, in
the case of the payment of Principal, in each case after the Trustee shall have
received the amounts due from the Issuer of the Bonds, by credit of same day
funds to the account indicated for Cede & Co. in the Certificate Register.
Payments received by the Trustee on or prior to 2:00 p.m., New York City time,
shall be credited to DTC that same day and payments received after such time
shall be credited the following Business Day. Notwithstanding any other
provisions in this Agreement, the right of the Holder of any Certificate to
receive any of the payments described above in this Section 2.08 (ii), and to
institute suit for the enforcement of any such payment on or after the date such
payment is payable, shall not be impaired without the consent of such Holder.

      (iii) Certificates of which Cede & Co. shall be the Holder shall be
initially issued in the form of one or more separate single Certificates for
each separate class of Certificates identified in the Series Trust Agreement to
be issued hereunder, aggregating in each case to the amount of each separate
stated maturity of the Certificates, or in such other manner as is required by
DTC. Upon initial issuance, the ownership of each such Certificate shall be
registered in the Certificate Register in the


                                      B-10
<PAGE>   21
name of Cede & Co., as nominee for DTC. The Depositor and the Trustee may treat
DTC (or its nominee) as the sole and exclusive owner of each Certificate
registered in its name for the purposes of payment of Interest, Principal and/or
Callable Principal represented thereby, giving any notice permitted or required
to be given to Holders under this Agreement, registering the transfer of such
Certificate, obtaining any consent or other action to be taken by Holders and
for all other purposes whatsoever, and neither the Depositor nor the Trustee
shall be affected by any notice to the contrary. Neither the Depositor nor the
Trustee shall have any responsibility or obligation to any Participant, any
Person claiming a beneficial ownership interest in such Certificate under or
through DTC or any Participant or any other Person that is not shown on the
Certificate Register as being a Holder of such Certificate, with respect to the
accuracy of any records maintained by DTC or any Participant; the payment by DTC
or any Participant of any amount in respect of Principal, Interest and/or
Callable Principal represented by such Certificate; any notice (or the
timeliness thereof) that is permitted or required to be given to Holders of such
Certificate under this Agreement; or any consent given or other action taken by
DTC as the Holder of such Certificate. Upon delivery by DTC to the Trustee of
written notice to the effect that DTC has determined to substitute a new nominee
in place of Cede & Co., and subject to the provisions of section 2.03 hereof
limiting the obligations of the Trustee to register transfers of or to exchange
Certificates, the words "Cede & Co." in this Agreement shall refer to such new
nominee of DTC.

      (iv) DTC may determine to discontinue providing its services with respect
to Certificates at any time by giving 90 days prior written notice to the
Depositor and the Trustee and discharging its responsibilities with respect
thereto under applicable law. Following receipt of such notice from DTC, the
Trustee shall promptly notify the Rating Agency. In connection therewith, the
Trustee and the Depositor will cooperate with DTC in taking appropriate action
after reasonable notice (a) to make available one or more separate physical
certificates evidencing the Certificates to any Participant having Certificates
credited to its DTC account or (b) to arrange for another securities depository
to maintain custody of physical certificates evidencing such Certificates. Upon
(1) the resignation of DTC from its functions as depository in accordance
herewith, provided that the Depositor is unable to arrange for another
securities depository to act as successor to DTC, (2) the election by the
Depositor to terminate book-entry registration of the Certificates (which
election shall only be made if the Depositor determines that such election will
not adversely affect the Holders), (3) the delivery of written notice to the
Trustee through DTC, from Holders of Outstanding Certificates representing at
least a majority of the Voting Rights, that such Holders elect to terminate
book-entry registration of the Certificates, (4) a default in payment of any
Interest, Principal or Callable Principal due on the Bonds, which default
remains uncured for 10 days, and the election by the Trustee to terminate
book-entry registration of the Certificates, or (5) the occurrence of an
Available Information Event (provided that the financial statements and other
information about the Issuer of the Bonds referred to in Section 5.15 hereof are
not thereafter available to the Trust), the Depositor shall notify DTC and,
except in the case of item (4) above, the Trustee of such event, whereupon DTC
is required under the Letter of Representations to notify the Participants of
the availability through DTC of physical certificates evidencing the
Certificates. In such event, DTC is required under the Letter of Representations
to promptly deliver to the Trustee the physical certificates evidencing such
Certificates, whereupon the Trustee at the expense of the Depositor shall
deliver physical certificates evidencing the Certificates to any Participant


                                      B-11
<PAGE>   22
having Certificates credited to its account at DTC and the provisions of this
Agreement shall then apply irrespective of this Section 2.08.

      (v) In connection with any notice or other communication to be provided to
Holders pursuant to this Agreement by the Trustee with respect to any consent or
other action to be taken by Holders, the Trustee shall establish a record date
for such consent or other action and give DTC notice of such record date not
less than 15 calendar days in advance of such record date to the extent
possible. Such record date shall be the later of thirty (30) days prior to the
first solicitation of such consent or other action or the date of the most
recent list of Holders furnished to the Trustee pursuant to Section 6.01 hereof.

      (vi) In the event that Bonds are redeemed and Certificates are
correspondingly redeemed and the Certificates are registered in the name of Cede
& Co., as nominee for DTC, the Certificates shall be redeemed and terminated
without action by the Holder thereof, all as provided in the Letter of
Representations.

      Section 2.09. Action or Consent of Holders. The Voting Rights on the
Certificates shall be apportioned by the Trustee among the Holders, as of the
applicable record date as determined by the Trustee pursuant to Section 2.08(v)
hereof, of the Outstanding Certificates in proportion to the Accreted Value or,
with respect to Stripped Bond Certificates, Callable Stripped Bond Certificates
and Pooled Certificates, the principal amount, of each class of Certificates,
and within each class, pro rata by aggregate Accreted Value or principal amount,
as applicable. In the event of any action or consent requiring the vote of the
owners of any Bonds at any time when the Certificates are held in the DTC
book-entry form, the Trustee, upon receipt of the Bond proxy, shall notify DTC
(in its capacity as the Holder of the Certificates) of such action. Under
current procedures the Depositor expects that DTC will notify the Participants
who will notify the Beneficial Owners of the Certificates of such an event.
Thereafter, the Trustee shall vote solely in accordance with such proxies and
shall apportion its voting powers on the basis of the votes cast by the Holders,
based upon the direction the Holders have received from the Beneficial Owners.
If the Certificates are not then held by DTC or any other depository, the
Trustee, upon receipt of the Bond proxy, shall notify the Holders directly of
such action and shall vote in the same manner as noted above. The Trustee shall
cast its vote in connection with the foregoing vote on the Bonds in proportion
to the Voting Rights on the Certificates held by the Holders or groups of
Holders directing it, notwithstanding that such Holder or groups of Holders may
give contrary instructions or that such instructions may conflict.

      The Trustee shall at no time vote for or consent to any action (i) to the
extent that such vote or consent could reasonably be expected to alter the
status of the Trust as a grantor trust for federal income tax purposes, (ii)
prior to the filing of a bankruptcy petition by or against the Issuer of the
Bonds or the commencement of any other similar proceeding, if such action would
alter the timing or amount of any payment on such Bonds or (iii) prior to the
filing of a bankruptcy petition by or against the Issuer of Bonds, or the
commencement of any other similar proceeding, if such action would result in the
exchange or substitution of any of such outstanding Bonds pursuant to a plan for
the refunding or refinancing of such Bonds. In connection with any vote, the
Trustee may request, as a condition


                                      B-12
<PAGE>   23
precedent to casting any vote, that it be provided with an opinion of Counsel
that the consent or action will not alter the status of the Trust as a grantor
trust for federal income tax purposes, which Opinion of Counsel shall be an
expense of the Holders voting in favor of the proposed action. The Trustee in
requesting such opinion shall inform the Holders of the potential expense of the
Opinion of Counsel.

      In no event shall the Depositor be allowed or entitled (other than in its
capacity as a Participant for a Beneficial Owner) to vote, directly or
indirectly, any Certificates.

      The Trustee shall also transmit to DTC or, if the Certificates are not
then held by DTC or any other depository, the Holders as provided in Section
9.04 hereof, any communications from the Issuer or from a third party (other
than the Issuer) to the Trustee as bondholder, upon receipt from such Issuer or
third party, respectively, of assurances that the Trustee's reasonable expenses
will be reimbursed by such Issuer or third party. If the Trustee does not
receive such assurances, then the Trustee, at the sole discretion of the
Depositor and at the expense of the Trust, shall transmit or cause to be
transmitted any such communications to DTC or, if the Certificates are not then
held by DTC or any other depository, the Holders as provided in Section 9.04
hereof.

      Section 2.10. Transfer of Certificates Held by DTC to Successor
Depository. (a) If the Depositor elects to direct that the Trustee deliver
Certificates with respect to a particular Series Trust Agreement in the name of
and to DTC, as the depository hereunder, or its nominee, said Certificates may
not thereafter be transferred except:

      (i) to any successor of DTC or its nominee;

      (ii) to any substitute depository not objected to by the Trustee, upon (1)
   the resignation of DTC or its successor (or any substitute depository or its
   successor) from its functions as depository or (2) a determination by the
   Depositor that it is in the best interest of the Depositor (and will not
   adversely affect the Holders) or the Holders to remove DTC or its successor
   (or any substitute depository or its successor); or

      (iii) as provided in Section 2.08(iv) hereof;

provided, that any successor of DTC or substitute depository referred to above
shall be a clearing agency registered with the Commission and shall otherwise be
qualified under any applicable laws to provide the services proposed to be
provided by it.

      Section 2.11. Temporary Certificates. The Certificates may be initially
delivered in temporary form exchangeable for definitive Certificates when ready
for delivery, which temporary Certificates shall be printed, lithographed or
typewritten, shall be of such denominations as may be determined by the Trustee,
shall be in fully registered form and shall contain such reference to any of the
provisions hereof as may be appropriate. Every temporary Certificate shall be
executed and delivered by the Trustee upon the same conditions and terms and in
substantially the same manner as definitive certificates. If temporary
Certificates are issued, the Trustee shall execute and deliver definitive


                                      B-13
<PAGE>   24
Certificates without delay, and in that case upon demand of the Holder of any
temporary Certificates such temporary Certificates shall be exchanged without
cost to such Holder for definitive Certificates at the office of the Trustee
upon surrender of such temporary Certificates, and until so exchanged such
temporary Certificates shall be entitled to the same benefit, protection and
security hereunder as the definitive Certificates executed and delivered
hereunder. All temporary Certificates surrendered pursuant to the provisions of
this Section 2.11 shall be canceled by the Trustee, shall not be redelivered and
shall be disposed of pursuant to Section 2.07.


                                   ARTICLE III

                        CERTAIN OBLIGATIONS OF HOLDERS OF
                      CERTIFICATES; DEPOSITOR'S WARRANTIES

      Section 3.01. Filing Proofs, Certificates and Other Information. Any
Holder presenting Certificates for surrender or registration of transfer or
exchange may be required to file such proof of residence, or other matters or
information, to execute such certificates and to make such representations and
warranties as the Trustee may reasonably deem necessary or proper. The Trustee
may withhold the delivery or delay the surrender of or registration of transfer
or exchange of any Certificate until such proof or other information is filed,
such certificates are executed or such representations and warranties are made.

      Section 3.02. Payment of Taxes or Other Governmental Charges. If any tax
or other governmental charge shall become payable by or on behalf of the
Trustee, including any tax or charge required to be withheld from any payment
made to or by the Trustee under the provisions of any applicable law, with
respect to any Certificate or with respect to the Interest, Principal or
Callable Principal (or portions thereof) evidenced by any Certificate, such tax
or governmental charge shall be payable by the Holder of such Certificate and
may be so withheld by the Trustee. The surrender of or registration of transfer
or exchange of any Certificate may be refused until such payment is made.

      Section 3.03. Depositor's Warranties. In the case of each delivery of
Bonds to the Trustee, the Depositor shall be deemed thereby to represent and
warrant to the Trustee that the Depositor is duly authorized to so deliver such
Bonds and that immediately prior to the delivery thereof the Depositor owned
such Bonds free and clear of any lien, pledge, encumbrance or other security
interest, and such delivery is irrevocable and free of any continuing claim by
the Depositor, except for the Retained Amount. The Depositor shall further be
deemed by such delivery to represent and warrant to the Trustee that the
prospectus and prospectus supplement prepared by the Depositor with respect to
the Certificates makes such disclosure with respect to the Bonds as is required
by applicable federal and state securities laws. Such representations and
warranties shall survive the delivery of such Bonds and the Certificates in
respect thereof.

the Trustee shall have received all or any part of the Callable Principal due
upon maturity or earlier redemption of the underlying Bonds or on any Interest
Payment Date, the Trustee shall pay to the Holder thereof upon presentation and
surrender of its Certificates, in lawful money of the United States of America,

      Any Callable Principal Certificate which is not redeemed on the First Call
Date shall be terminated and deemed involuntarily surrendered by the Holder
thereof in exchange for a principal amount of the Bonds underlying such Callable
Principal Certificate equal to the face amount of such Callable Principal
Certificate, whether or not such Holder has requested such exchange. No action
by

Interest Payment Date preceding the maturity date, as of the applicable record
date of the underlying Bonds, and (ii) with respect to the maturity date, upon
presentation of its Certificates, in lawful money of the United States of
America, by check no later than one Business Day after receipt of funds by the
Trustee (in the case of clause (i) above, sent by first-class mail to the
address of the Holder set forth in the Certificate Register), the entire amount
of such Interest and/or Principal; in each case less any taxes or governmental
charges required to be withheld from such payment by the Trustee.

      With respect to any Callable Stripped Bond Certificate, on or after the
stated maturity date, the redemption date or the Interest Payment Date, as
applicable, of the Callable Principal evidenced thereby, if the Issuer shall
have paid and the Trustee shall have received the Interest or all or any part of
the Callable Principal evidenced thereby due upon maturity or earlier redemption
of the underlying Bonds or on any Interest Payment Date, the Trustee shall pay
to the Holder thereof (i) with respect to each Interest Payment Date preceding

thereof in exchange for a principal amount of the Bonds underlying such Callable
Stripped Bond Certificate equal to the face amount of such Callable Stripped
Bond Certificate, whether or not such Holder has requested such exchange. No
action by such Holder shall be required to effect such termination, which shall
be carried out by the Trustee pursuant to the terms of this Agreement.

<PAGE>   27
      With respect to any Pooled Certificate, on or after the stated maturity
date, the redemption date or the Interest Payment Date, as applicable, of the
Interest, Principal or Callable Principal evidenced thereby, if the Issuer shall
have paid and the Trustee shall have received Interest on any of the Bonds in
the Trust evidenced thereby or all or any part of the Principal or Callable
Principal on any of the Bonds in the Trust evidenced thereby due upon maturity
or earlier redemption of such Bonds or on any Interest Payment Date, the Trustee
shall pay to the Holder thereof (i) with respect to each Interest Payment Date
preceding the maturity date or redemption date, as applicable, as of the
applicable record date of the underlying Bonds, and (ii) with respect to the
maturity date or redemption date, as applicable, upon presentation of its
Certificates, in lawful money of the United States of America, by check no later

Principal or Callable Principal so paid and received, less any Retained Amount,
or, in the case of a Certificate redeemed in part, the amount of such Callable
Principal so redeemed; in each case less any taxes or governmental charges
required to be withheld from such payment by the Trustee.

      With respect to any payment of Interest, Principal or Callable Principal,
as applicable, that constitutes a Retained Amount, the Trustee shall remit such
Retained Amount to the Depositor, in immediately available funds, within one
Business Day of receipt by the Trustee from the Issuer.

      When making any payment to a Holder of a Certificate or, with respect to
any Retained Amount, to the Depositor, under this Agreement, the Trustee shall
round down such payment to the nearest whole cent.

      Notwithstanding any other provisions in this Agreement, the right of the
Holder of any Certificate to receive any of the payments described above in this
Section 4.01, and to institute suit for the enforcement of any such payment on
or after the date such payment is payable, shall not be impaired without the
consent of such Holder.

      Section 4.02. Segregation of Moneys Received from Issuers in Respect of
Bonds. All moneys received from the Issuers of Bonds or otherwise by the Trustee
in respect of Bonds evidenced by Certificates issued hereunder shall be held by
it without interest in a segregated trust account (which account shall contain
two subaccounts, one for interest payments on the Bonds and the second for
principal and redemption premium payments on the Bonds) for each issue of Bonds
held in trust until required to be disbursed in accordance with the provisions
of this Agreement or as otherwise required by law and such moneys shall be
segregated by separate recordation on the books and records of the Trustee.
Payments whose character as principal, redemption premium or interest on the
Bonds cannot be determined shall be deposited in the subaccount for principal
until distributed pursuant to Section 5.03(b) hereof.

      Section 4.03. Paying Agent. Each Paying Agent other than the Trustee shall
execute and deliver to the Trustee an instrument in which such Paying Agent

<PAGE>   28
      (i) hold all sums held by it for the payment of amounts due with respect
   to the Bonds in trust for the benefit of the Persons entitled thereto until
   such sums shall be paid to such Persons or otherwise disposed of as herein
   provided and pay such sums to such Persons as herein provided;

      (ii) give the Trustee notice of any default by the Issuer (or any other
   obligor upon the Bonds) of which it has actual knowledge in the making of any
   payment required to be made with respect to the Certificates.


                                    ARTICLE V

                          THE TRUSTEE AND THE DEPOSITOR

      Section 5.01. Eligibility of Trustee; Disqualification. The Trustee shall
at all times satisfy the requirements of TIA Section 310(a). The Trustee shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recent published annual report of condition and it shall have a long term
unsecured debt or deposit rating of A-2 or better by Moody's Investors Service,
Inc. and A by Standard & Poor's Ratings Group or the equivalent rating thereof
by the Rating Agency (if other than Moody's Investors Service, Inc., or Standard
& Poor's Ratings Group). The Trustee shall comply with TIA Section 310(b);
provided, however, that there shall be excluded from the operation of TIA
Section 310(b)(1) any series trust deposit agreements under which other
securities are outstanding evidencing ownership interests in bonds of the Issuer
of the Bonds if the requirements for such exclusion set forth in TIA Section
310(b)(1) are met.

      Section 5.02. Trustee's Duties on Default; No Liability of the Trustee or
the Depositor on the Bonds. If an event of default on the Bonds has occurred and
is continuing, the Trustee shall exercise the rights and powers vested in it by
this Agreement and use the same degree of care and skill in their exercise as a
prudent Person would exercise or use under the circumstances in the conduct of
such Person's own affairs.

      The Trustee shall have the legal power to exercise all of the rights,
powers and privileges of a holder of the Bonds in which the Certificates
evidence an interest. However, neither the Trustee (except as specifically
provided in Section 5.03 or elsewhere herein or in the TIA) nor the Depositor
shall be under any obligation whatsoever to appear in, prosecute or defend any
action, suit or other proceeding in respect of Bonds or Certificates.

      The sole obligor with respect to any Bond is the Issuer thereof or any
other entity obligated to make payments to or on behalf of the Issuer thereof
(or its trustee or other applicable fiduciary) with respect to such Bond.
Neither the Trustee nor the Depositor shall have any obligation on or with
respect to the Bonds except as provided in this Article V with respect to the
Trustee; and their respective obligations with respect to Certificates shall be
solely as set forth in this Agreement.

      If there is an event of default (as defined in the indenture or other
document pursuant to which the Bonds were issued) with respect to any Bond and
such default is known to the Trustee, the Trustee


                                      B-18
<PAGE>   29
shall promptly give notice to DTC or, if the Certificates are not then held by
DTC or any other depository, directly to Holders thereof as provided in Section
9.04 hereof (and in the manner and to the extent provided in TIA Section 313(c))
within 90 days after such event of default occurs. Such notice shall set forth
(a) the identity of the issue of Bonds, (b) the date and nature of such default,
(c) the face amount of the Interest, Principal or Callable Principal to which
such default relates, (d) the identifying numbers of the class of Certificates,
or any combination, as the case may be, evidencing the Interest, Principal or
Callable Principal (or portions thereof) described above in clause (c), and (e)
any other information which the Trustee may deem appropriate. Except in the case
of a default in payment of Principal or Interest (including payments pursuant to
a redemption of any Certificate), the Trustee may withhold the notice to Holders
if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders.

      Holders of Certificates shall have no recourse against the Depositor or
the Trustee for payment defaults on the Bonds.

      Section 5.03. Collection of Indebtedness and Suits for Enforcement by
Trustee; Distribution of Amounts Received in Respect of Defaulted Bonds.

      (a) If:

      (i) default is made in the payment of any installment of interest on any
   Bond when the same becomes due and payable, and such default continues
   unremedied for the period specified in the indenture (as identified in
   Exhibit A to the Series Trust Agreement), or, if no such period is specified,
   five days, after receipt by the Issuer of notice thereof from the Trustee or
   receipt by the Issuer and the Trustee of notice thereof from the Holders of
   Outstanding Certificates representing at least 25% of the Voting Rights; or

      (ii) default is made in the payment of the principal of or any installment
   of the principal of any Bond when the same becomes due and payable, and such
   default continues unremedied for the period specified in the indenture (as
   identified in Exhibit A to the Series Trust Agreement), or, if no such period
   is specified, thirty (30) days, after receipt by the Issuer of notice thereof
   from the Trustee or receipt by the Issuer and the Trustee of notice thereof
   from the Holders of Outstanding Certificates representing at least 25% of the
   Voting Rights;

and the Issuer shall, upon demand of the Trustee, fail to pay forthwith to the
Trustee, for the benefit of the Holders, the whole amount then due and payable
on such Bonds for principal and interest, with interest upon the overdue
principal, at the rate borne by the Bonds 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 its agents and counsel, to the extent permitted by law (such
event, an "Issuer Payment Default"), then the Trustee, in its own name and as
trustee of an express trust, subject to provision being made by the Holders for
indemnification against costs, expenses and liabilities in a form satisfactory
to the Trustee, shall institute a Proceeding for the collection of the sums so
due and unpaid, and shall prosecute such Proceeding to judgment or


                                      B-19
<PAGE>   30
final decree or settlement, and shall enforce the same against the Issuer or
other obligor upon the Bonds and collect in the manner provided by law out of
the property of the Issuer or other obligor upon the Bonds, wherever situated,
the moneys adjudged or decreed to be payable, unless otherwise directed by
Holders of Outstanding Certificates representing not less than a majority of the
voting Rights. In connection therewith, the Trustee shall use its best
reasonable efforts in accordance with such normal and customary procedures it
shall deem necessary or advisable, and shall have the power and authority,
acting alone, to do any and all things in connection therewith and the
administration of the Trust as it may deem necessary or advisable.

      (b) In the event that the Trustee receives money or other property in
respect of the Bonds (other than a scheduled interest payment with respect to an
Interest Payment Date, the scheduled payment of principal on or with respect to
the stated maturity date of the Bonds, or the payment of principal and any
redemption premium on or with respect to the earlier redemption of the Bonds) as
a result of a payment default on the Bonds, or actual notice that such moneys or
other property will be paid to the Trustee, the Trustee shall promptly give
notice (as provided in Section 9.04 hereof) to DTC or, if the Certificates are
not then held by DTC or any other depository, directly to the Holders of the
Certificates then outstanding and unpaid. Such notice shall state that, not
later than thirty (30) days after the receipt of such moneys or other property,
the Trustee shall allocate and distribute such moneys or other property to the
Holders of the Outstanding Certificates then unpaid, in proportion to the
Accreted Value or, with respect to Stripped Bond Certificates, Callable Stripped
Bond Certificates and Pooled Certificates, the principal amount, of each class
of Outstanding Certificates, and within each class, pro rata by aggregate
Accreted Value or principal amount, as applicable. Property received, other than
cash, shall be liquidated by the Trustee in a commercially reasonable manner and
the proceeds thereof, after deduction of all reasonable costs of such
liquidation, distributed in cash, only to the extent necessary to avoid
distribution of fractional securities. The Trustee shall not be responsible for
the failure of any Person to maximize the price at which such property may be
sold. No Person effecting a sale on behalf of the Trustee shall be liable
therefor so long as such sale is effected in a commercially reasonable manner.

      Section 5.04. Control by Holders. The Holders of Outstanding Certificates
representing a majority of the Voting Rights shall, subject to provision being
made for indemnification against costs, expenses and liabilities in a form
satisfactory to the Trustee, have the right to direct the time, method and place
of conducting any Proceeding for any remedy available to the Trustee with
respect to any Issuer Payment Default; provided, however, that:

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

      (ii) subject to Sections 2.09 and 5.11, the Trustee need not take any
   action that it determines might cause it to incur any liability or might
   materially adversely affect the rights of any Holders not consenting to such
   action.


                                      B-20
<PAGE>   31
      Section 5.05.  Waiver of Past Defaults.

      The Holders of Outstanding Certificates representing not less than a
majority of the Voting Rights may waive any past default and its consequences
except (i) an Issuer Payment Default or other default in the payment of
principal of or interest on any of the Certificates or (ii) a default in respect
of a covenant or provision hereof which cannot be modified or amended without
the consent of the Holder of each Certificate. In the case of any such waiver,
the Depositor, the Trustee and the Holders shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend to
any subsequent or other default or impair any right consequent thereto.

      Section 5.06. Maintenance of Offices and Agencies by the Trustee. Until
termination of this Agreement in accordance with its terms, the Trustee shall
maintain (a) facilities in the City of New York for the execution and delivery,
payment, surrender and registration of transfer and exchange of Certificates,
all in accordance with the provisions of this Agreement, and (b) such other
agents, if any, as the Trustee and the Depositor may agree from time to time.

      Section 5.07. Prevention of or Delay in Performance by the Trustee or the
Depositor. Neither the Trustee nor the Depositor shall incur any liability to
any Holder of any Certificate, if by reason of any provision of any present or
future law, or regulation thereunder, of any governmental authority, or by any
reason of any act of God or war or other circumstance beyond the control of the
relevant party, the Trustee or the Depositor shall be prevented or forbidden
from doing or performing any act or thing which the terms of this Agreement
provide shall be done or performed; and neither the Trustee nor the Depositor
shall incur any liability to any Holder of a Certificate by reason of any
non-performance or delay, caused as aforesaid, in the performance of any act or
thing which the terms of this Agreement provide shall or may be done or
performed, or by reason of any exercise of, or failure to exercise, any
discretion provided for in this Agreement.

      Section 5.08. Liability of the Trustee and the Depositor. (a) Neither the
Trustee nor the Depositor assumes any obligation or shall be subject to any
liability under this Agreement to Holders of Certificates, other than liability
for its own negligent action, its own negligent failure to act or its own
willful misconduct, in the performance of such duties as are specifically set
forth in this Agreement or the TIA; further provided, that:

      (i) the Trustee shall not be liable except for the performance of such
   duties as are specifically set out in this Agreement and no implied covenants
   or obligations shall be read into this Agreement against the Trustee;

      (ii) the Trustee may conclusively rely, as to the truth of the statements
   and the correctness of the opinions expressed therein, in the absence of bad
   faith on the part of the Trustee, upon certificates or opinions conforming to
   the requirements of this Agreement (but the Trustee shall examine the
   evidence furnished to it pursuant to TIA Section 314 to determine whether or
   not such evidence conforms to the requirements of this Agreement);


                                      B-21
<PAGE>   32
      (iii) the Trustee shall not be liable for any error of judgment made in
   good faith by a Responsible Officer unless it is proved that the Trustee was
   negligent in ascertaining the pertinent facts; and

      (iv) to the extent that the Holders of Outstanding Certificates
   representing not less than a majority of the Voting Rights direct the Trustee
   with respect to the time, method and place of conducting any Proceeding for
   any remedy available to the Trustee with respect to an Issuer Payment
   Default, the Trustee shall not be liable with respect to any action it takes
   or omits to take in good faith in accordance with such direction.

      Neither DTC nor any registrar with which Bonds are maintained as
book-entry credits shall be deemed agents of the Trustee. The Trustee may own
and deal (i) in bonds of the same issue and maturity as the Bonds and (ii) in
Certificates.

      The Trustee shall be under no liability to any party hereto, or to any
Holder, by reason of any failure on the part of the Depositor or any maker,
guarantor, endorser or other signatory of any document or instrument, including
any Bond, or any other Person to perform such Person's obligations under any
such document or instrument.

      The Trustee shall not be responsible for the sufficiency or accuracy, the
form or the execution, validity, value or genuineness of any document or
property received or held by it hereunder, including without limitation any
Bonds, or the authority of the Depositor in executing this Agreement.

      The Trustee assumes no responsibility for the correctness of the recitals
to the Certificates or to any document issued in connection with the sale of the
Certificates, other than its signature under the Certificates.

      ANY ACTION OR PROCEEDING ALLEGING ANY BREACH BY THE TRUSTEE OF ITS DUTIES
UNDER THIS AGREEMENT SHALL BE PROSECUTED ONLY IN A STATE OR FEDERAL COURT
LOCATED IN THE STATE OF NEW YORK, COUNTY OF NEW YORK. THE TRUSTEE SHALL HAVE THE
RIGHT AT ANY TIME TO SEEK INSTRUCTIONS FROM ANY COURT OF COMPETENT JURISDICTION.

      The Trustee shall be deemed to have exercised reasonable care in the
custody and preservation of the Bonds in its possession if the Bonds are held in
the manner specified in the Officer's Certificate of the Trustee and are
accorded treatment substantially equal to that which a prudent Person accords
its own property.

      The Trustee shall at all times maintain a fidelity bond in reasonable form
and amount to protect against loss due to dishonest or fraudulent action by its
employees in connection with its obligations hereunder.


                                      B-22
<PAGE>   33
      The Trustee may consult with and rely upon the calculations of an advisor
(which may be the Depositor) in connection with any calculation of Accreted
Value to the extent such amount must be determined in order for the Trustee to
carry out its duties hereunder.

      The Trustee may consult with counsel of its selection, and the advice of
such counsel or any Opinion of Counsel selected by the Trustee with due care
shall be full and complete authorization and protection in respect of any action
taken, suffered or omitted by it hereunder in reliance thereon.

      The Trustee may request and rely upon and shall be protected in acting or
refraining from action upon any resolution, certificate signed by an authorized
officer, certificate of auditors or any other certificate, statement,
instrument, opinion, report, notice, facsimile transmission, request, consent,
order, appraisal, bond or other paper or document reasonably believed by it to
be genuine and to have been signed or presented by the proper party or parties.

      The Trustee shall be under no obligation to exercise any of the trusts or
powers vested in it by this Trust Agreement or to institute, conduct or defend
any litigation hereunder or in relation hereto, at the request, order or
direction of any of the Holders, pursuant to the provisions of this Series Trust
Agreement, unless such Holders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities which may be
incurred therein or thereby.

      The Trustee may execute any of the trusts or powers hereunder or perform
any duties hereunder either directly or by or through agents or attorneys or a
custodian and shall not be liable for any misconduct or negligence of any such
agents or attorneys selected with due care by it.

      (b) Any application by the Trustee for written instructions from the
Depositor may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Series Trust Agreement
and the date on and/or after which such action shall be taken or such omission
shall be effective, if, but only if, the obligations of the Trustee with respect
to such proposed action or omission, in the view of the Trustee, are not set
forth reasonably clearly in this Series Trust Agreement. The Trustee shall not
be liable for any action taken by, or omission of, the Trustee in accordance
with a proposal included in such application on or after the date specified in
such application (which date shall not be less than ten (10) Business Days after
the date a Responsible Officer of the Depositor actually receives such
application, unless any such Responsible Officer shall have consented in writing
to any earlier date) unless, prior to taking any such action (or the effective
date in the case of an omission), the Trustee shall have received written
instructions in response to such application specifying the action to be taken
or omitted; provided, however, that this provision shall not protect the Trustee
from liability for any action or omission constituting willful misconduct, bad
faith or negligence.

      Section 5.09. Obligation of the Depositor.  (a) The Depositor shall:

      (i) on behalf of the Trust, prepare and file with the Commission,
   following the execution thereof by the Trustee if so requested by the
   Depositor, and file with the Trustee, within 15 days


                                      B-23
<PAGE>   34
   after the Depositor on behalf of the Trust is required to file the same with
   the Commission, copies of the annual reports and of the information,
   documents and other reports (or copies of such portions of any of the
   foregoing as the Commission may from time to time by rules and regulations
   prescribe), if any, which the Depositor on behalf of the Trust may be
   required to file with the Commission pursuant to Section 13 or 15(d) of the
   Exchange Act (collectively, "reports") with respect to the Trust. A copy of
   each such report shall be provided to the Trustee at least 10 Business Days
   prior to the date required for filing. The names of such reports and the
   dates on which they are required to be filed with the Commission shall be
   specified to the Trustee by the Depositor within 180 days after the Closing
   Date;

      (ii) file with the Trustee, within 15 days after the Depositor is required

   and covenants of this Agreement, if any, as may be required to be filed with
   the Commission from time to time by such rules and regulations;

      (iii) supply to the Trustee (and the Trustee shall transmit by mail to all
   Holders described in TIA Section 313(c), in the manner and to the extent
   provided therein) such summaries of any information, documents and reports
   required to be filed by the Depositor pursuant to clauses (i) and (ii) of
   this Section 5.09(a), if any, as may be required by rules and regulations
   prescribed from time to time by the Commission; and

      (iv) after an Available Information Event, on behalf of the Trust, prepare
   and file with the Commission, following the execution thereof by the Trustee
   if so requested by the Depositor, and file with the Trustee, within 15 days
   after the Depositor on behalf of the Trust is required to file the same with
   the Commission, reports of the kind referred to in clause (i) of this Section
   5.09(a) with respect to the Issuer of the Bonds, to the extent such reports
   are then available to the Depositor, for as long as the Depositor on behalf
   of the Trust is required to file such reports under the Exchange Act. Such
   reports shall include quarterly and annual financial statements and other
   information of the type required to be filed on Form 8-K under the Exchange
   Act with respect to the Issuer of the Bonds. A copy of each such report shall
   be provided to the Trustee at least 10 Business Days prior to the date
   required for filing. If such reports and information are not available to the
   Depositor at a time when such reports and information are required to be
   filed with the Commission by the Depositor on behalf of the Trust, the
   Depositor shall cause the removal of the Certificates from the DTC book-entry
   system as set forth in Section 2.08(iv)(5) of this Agreement and shall notify
   the Issuer that the Holders of Certificates constitute record holders of the
   Bonds for purposes of the Exchange Act.

      (b) The Depositor shall deliver to the Trustee, not less often than
annually, an Officer's Certificate signed by an Authorized Officer who is the
principal executive officer, principal financial officer or principal accounting
officer of the Depositor, dated as of the date set forth in the Series Trust
Agreement for such year, stating that:


                                      B-24
<PAGE>   35
      (i) a review of the activities of the Depositor during such fiscal year
   and of performance under this Agreement has been made under such Authorized
   Officer's supervision; and

      (ii) to the best of such Authorized Officer's knowledge, based on such
   review, the Depositor has fulfilled all of its obligations under this
   Agreement throughout such year, or, if there has been a default in the
   fulfillment of any such obligation, specifying each such default known to
   such Authorized Officer and the nature and status thereof. A copy of such
   certificate may be obtained by any Holder by a request in writing to the
   Depositor addressed to the Corporate Trust Office of the Trustee.

      (c) If and only if the Series Trust Agreement provides for the pledge of
the Bonds to the Trustee (and not merely the transfer, assignment, conveyance
and sale, without recourse, thereof to the Trustee), on the Closing Date, the
Depositor shall furnish to the Trustee an Opinion of Counsel either stating
that, in the opinion of such counsel, such action has been taken with respect to
the recording and filing of this Agreement, any agreements supplemental hereto
and any other requisite documents, and with respect to the execution and filing
of any financing statements and continuation statements as are necessary to
perfect and make effective the lien and security interest of this Agreement and
reciting the details of such action, or stating that, in the opinion of such
counsel, no such action is necessary to make such lien and security interest
effective.

      (d) If and only if the Series Trust Agreement provides for the pledge of
the Bonds to the Trustee (and not merely the transfer, assignment, conveyance
and sale, without recourse, thereof to the Trustee), at least annually after the
Closing Date, the Depositor shall furnish to the Trustee an Opinion of Counsel
either stating that, in the opinion of such counsel, such action has been taken
with respect to the recording, filing, re-recording and refiling of this
Agreement, any agreements supplemental hereto and any other requisite documents
and with respect to the execution and filing of any financing statements and
continuation statements as is necessary to maintain the lien and security
interest created by this Agreement and reciting the details of such action or
stating that in the opinion of such counsel no such action is necessary to
maintain the lien and security interest created by this Agreement. Such Opinion
of Counsel shall also describe the recording, filing, re-recording and refiling
of this Agreement, any agreements supplemental hereto and any other requisite
documents and the execution and filing of any financing statements and
continuation statements that will, in the opinion of such counsel, be required
to maintain the lien and security interest of this Agreement until such date in
the following calendar year.

      (e) If and only if the Series Trust Agreement provides for the pledge of
the Bonds to the Trustee (and not merely the transfer, assignment, conveyance
and sale, without recourse, thereof to the Trustee),

      (i) whenever any property or securities are to be released from the lien
   of this Agreement, the Depositor shall furnish to the Trustee an Officer's
   Certificate of the Depositor certifying or stating the opinion of each Person
   signing such certificate as to the fair value (within 90 days of such
   release) of the property or securities proposed to be released and stating
   that in the opinion


                                      B-25
<PAGE>   36
   of such Person the proposed release will not impair the security under this
   Agreement in contravention of the provisions hereof.

      (ii) whenever the Depositor is required to furnish to the Trustee an
   Officer's Certificate of the Depositor certifying or stating the opinion of
   any signatory thereof as to the matters described in clause (i) above, the
   Depositor shall also furnish to the Trustee an Independent Certificate as to
   the same matters if the fair value of the property or securities and of all
   other property or securities released from the lien of this Agreement since
   the commencement of the then current calendar year, as set forth in the
   certificates required by clause (i) above and this clause (ii), equals 10% or
   more of the principal amount of the Outstanding Certificates, but such
   certificate need not be furnished in the case of any release of property or
   securities if the fair value thereof as set forth in the related Officer's
   Certificate of the Depositor is less than $25,000 or less than one percent of
   the then principal amount of the Outstanding Certificates.

      (iii) prior to the deposit with the Trustee of any securities that is to
   be made the basis for the authentication and delivery of Certificates, the
   withdrawal of cash constituting a part of the trust estate or the release of
   any property or securities subject to the lien of this Agreement, the
   Depositor shall furnish to the Trustee an Officer's Certificate of the
   Depositor certifying or stating the opinion of each Person signing such
   certificate as to the fair value (within 90 days of such deposit) to the
   Depositor of the securities to be so deposited.

      (iv) whenever the Depositor is required to furnish to the Trustee an
   Officer's Certificate of the Depositor described in clause (iii) above, the
   Depositor shall also deliver to the Trustee an Independent Certificate as to
   the same matters, if the fair value to the Depositor of the securities to be
   so deposited and of all other such securities made the basis of any such
   withdrawal or release since the commencement of the then current fiscal year
   of the Depositor, as set forth in the certificates delivered pursuant to
   clause (iii) above and this clause (iv), is 10% or more of the principal
   amount of the Outstanding Certificates, but such a certificate need not be
   furnished with respect to any securities so deposited, if the fair value
   thereof to the Depositor as set forth in the related Officer's Certificate of
   the Depositor is less than $25,000 or less than one percent of the principal
   amount of the Outstanding Certificates.

      (v) subject to the payment of its fees and expenses hereunder, the Trustee
   may, and when required by the provisions of this Agreement, shall, execute
   instruments to release property from the lien of this Agreement, or convey
   the Trustee's interest in the same, in a manner and under circumstances that
   are consistent with the provisions of this Agreement. No party relying upon
   an instrument executed by the Trustee in connection therewith shall be bound
   to ascertain the Trustee's authority, inquire into the satisfaction of any
   conditions precedent or see to the application of any moneys.

      (vi) the Trustee shall at such time as there are no Outstanding
   Certificates and all sums due to the Trustee hereunder have been paid,
   release any remaining portion of the trust estate that


                                      B-26
<PAGE>   37
   secured the Certificates from the lien of this Agreement and release to the
   Depositor or any other Person entitled thereto any funds then included in the
   trust estate.

      (f) Upon any application or request by the Depositor to the Trustee to
take any action under the provisions of this Agreement, which action is subject
to the satisfaction of a condition precedent (including any covenants compliance
with which constitutes a condition precedent), the Depositor shall furnish to
the Trustee: (i) an Officer's Certificate stating that all conditions precedent,
if any, provided for in this Agreement relating to the proposed action have been
complied with, (ii) an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent, if any, have been complied with and (iii)
(if required by the TIA) an Independent Certificate from a firm of certified
public accountants meeting the applicable requirements of the TIA, except that,
in the case of any such application or request as to which the furnishing of
such documents is specifically required by any provision of this Agreement, no
additional certificate or opinion need be furnished. Every certificate or
opinion with respect to compliance with a condition or covenant provided for in
this Agreement shall include:

      (i) a statement that such signatory of such certificate or opinion has
   read or has caused to be read such covenant or condition and the definitions
   herein relating thereto;

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

      (iii) a statement that, in the judgment of each such signatory, such
   signatory has made such examination or investigations as is necessary to
   enable such signatory to express an informed opinion as to whether or not
   such covenant or condition has been complied with; and

      (iv) a statement as to whether, in the opinion of each such signatory,
   such condition or covenant has been complied with.

      Section 5.10. Preferential Collection of Claims Against Depositor. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent required by TIA
Section 311(a).

      Section 5.11. Resignation and Removal of the Trustee; Appointment of
Successor Trustee. The Trustee may at any time resign as Trustee hereunder by
written notice of its election so to do, delivered to the Depositor and the
Rating Agency as provided in Section 9.04 hereof, and such resignation shall
take effect upon the appointment of a successor Trustee and its acceptance of
such appointment as hereinafter provided. The Depositor may at any time
(including such time as the Trustee fails to comply with Section 5.01) remove
the Trustee as Trustee hereunder by written notice of its election to do so,
delivered to the Trustee and the Rating Agency as provided in Section 9.04
hereof, and such removal shall take effect upon the appointment of a successor
Trustee and its acceptance of such appointment as provided in the third
succeeding paragraph; provided, however, that


                                      B-27
<PAGE>   38
in the event of such removal, the Depositor shall negotiate in good faith with
the Trustee in order to agree regarding payment of the termination costs of the
Trustee resulting from such removal. Upon the designation of a successor Trustee
following either resignation by or removal of the Trustee, the Trustee shall
deliver to the successor Trustee all records relating to the Certificates in the
form and manner then maintained by the Trustee, which shall include a hard copy
thereof upon request of the successor Trustee.

      If at any time the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
property shall be appointed, or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, or the Trustee shall fail to comply with Section
5.01, then any Holder of a Certificate with respect to a particular issue of
Bonds which has been such a Holder for at least six (6) months or the Holders of
Outstanding Certificates representing ten percent (10%) of the Voting Rights for
the Outstanding Certificates of a series which is outstanding at such time may,
on behalf of himself, herself or themselves and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with
respect to the Bonds evidenced by such Certificates and the appointment of a
successor Trustee.

      In the event the Trustee resigns or is removed, the Trustee shall
reimburse the Depositor for any fees or charges previously paid to the Trustee
in respect of duties not yet performed under this Agreement which remain to be
performed by a successor Trustee and the Trustee shall promptly notify the
Rating Agency of its resignation or removal and any successor Trustee shall
promptly notify the Rating Agency of its appointment as provided in Section 9.04
hereof.

      In case at any time the Trustee acting hereunder notifies the Depositor
that it elects to resign or the Depositor notifies the Trustee that it elects to
remove the Trustee as Trustee, the Depositor shall, within ninety (90) days
after the delivery of the notice of resignation or removal, appoint a successor
Trustee, which shall be a bank with trust powers or a trust company having its
principal office in the United States of America and having a combined capital
and surplus of at least $50,000,000 and which is rated at least investment grade
by the Rating Agency. If no successor Trustee has been appointed as successor
Trustee within ninety (90) days after the Trustee has given written notice of
its election to resign or the Depositor has given written notice to the Trustee
of its election to remove the Trustee, as the case may be, the Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee. Every successor Trustee shall execute and deliver to its predecessor
and to the Depositor an instrument in writing accepting its appointment
hereunder, and thereupon such successor Trustee, without any further act or
deed, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor and for all purposes shall be the Trustee under
this Agreement, and such predecessor, upon payment of all sums due it and on the
written request of the Depositor, shall execute and deliver an instrument
transferring to such successor all rights, obligations and powers of such
predecessor hereunder, and shall duly assign, transfer and deliver all right,
title and interest in the Bonds and parts thereof to such successor. Any
successor Trustee shall promptly give notice of its appointment to the Holders
of Certificates for which it is successor Trustee as provided in Section 9.04
hereof.


                                      B-28
<PAGE>   39
      Any corporation into or with which the Trustee may be merged, consolidated
or converted shall be the successor of such Trustee without the execution or
filing of any document or any further act.

      Section 5.12. Indemnification by the Depositor. The Depositor agrees to
indemnify the Trustee and any of its agents, officers, directors or employees
for, and to hold them harmless against, any loss, liability or expense arising,
directly or indirectly, out of, relating to, or in connection with the
acceptance, administration or performance of their duties, or the duties of the
Trustee, as well as the costs and expenses of defending themselves against any
action, suit, or other proceeding involving any claim or liability arising,
directly or indirectly, out of, relating to or in connection with, this
Agreement, the Initial Trust Agreement or the exercise or performance of any of
their powers or duties hereunder or thereunder, other than any loss, liability
or expense arising out of (i) negligence, willful misconduct or bad faith on the
part of the Trustee or any of its agents, officers, directors or employees, or
(ii) any charges, fees or reimbursements that are expressly required by this
Agreement to be paid by the Holders or for which the Holders are expressly
required by this Agreement or have elected pursuant to the terms of this
Agreement to provide security or indemnity to the Trustee. Failure of the
Depositor to fulfill its obligations hereunder shall not relieve the Trustee
from fulfilling its duties under this Agreement.

      Any Person that proposes to assert the right to be indemnified under this
Section 5.12 (any such Person, an "Indemnified Party") shall, promptly after
receipt of notice of commencement of any action against such party in respect of
which a claim is to be made against the Depositor under this Section 5.12,
notify the Depositor of the commencement of such action, enclosing a copy of all
papers served, but the omission so to notify the Depositor shall not relieve the
Depositor from any liability that it may have to such Indemnified Party under
the foregoing provisions of this Section 5.12 unless, and only to the extent
that, such omission results in the forfeiture of rights or defenses by the
Depositor. If any such action is brought against an Indemnified Party and it
notifies the Depositor of its commencement, the Depositor shall be entitled to
participate in and, to the extent that it elects by delivering written notice to
the Indemnified Party promptly after receiving notice of the commencement of the
action from the Indemnified Party, to assume the defense of the action, with
counsel satisfactory to the Indemnified Party, and after notice from the
Depositor to the Indemnified Party of its election to assume the defense, the
Depositor shall not be liable to the Indemnified Party for any fees,
disbursements or other charges of counsel except as provided below and except
for the reasonable costs of investigation subsequently incurred by the
Indemnified Party in connection with the defense. The Indemnified Party shall
have the right to employ its own counsel in any such action, but the fees,
expenses and other charges of such counsel shall be at the expense of the
Indemnified Party unless (1) the employment of counsel by the Indemnified Party
has been authorized in writing by the Depositor, (2) the Indemnified Party has
reasonably concluded (based on advice of counsel) that there may be legal
defenses available to it or other Indemnified Parties that are different from or
in addition to those available to the Depositor, (3) a conflict or potential
conflict exists (based on advice of counsel to the Indemnified Party) between
the Indemnified Party and the Depositor (in which case the Depositor shall not
have the right to direct the defense of such action on behalf of the Indemnified
Party), or (4) the Depositor has not in fact employed counsel to assume the
defense of such action within 15 Business Days after receiving notice of the
commencement of the action, in each of which cases the reasonable


                                      B-29
<PAGE>   40
fees, disbursements and other charges of counsel shall be at the expense of the
Depositor. It is understood that the Depositor shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
reasonable fees, disbursements and other charges of more than one separate firm
admitted to practice in such jurisdiction at any one time for all Persons
entitled to indemnification hereunder. All such fees, disbursements and other
charges shall be reimbursed by the Depositor promptly as they are incurred. The
Depositor shall not be liable for any settlement of any action or claim effected
without its written consent (which consent shall not be unreasonably withheld).
The Depositor shall not, without the prior written consent of each Indemnified
Party, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action or proceeding relating to the matters
contemplated by this Section 5.12 (whether or not any Indemnified Party is a
party thereto), unless such settlement, compromise or consent includes an
unconditional release of each Indemnified Party from all liability arising or
that may arise out of such claim, action or proceeding. Notwithstanding any
other provision of this Section 5.12, if at any time an Indemnified Party shall
have requested the Depositor to reimburse the Indemnified Party for fees and
expenses of counsel, the Depositor agrees that it shall be liable for any
settlement effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by the Depositor of the aforesaid
request, (ii) the Depositor shall have received notice of the terms of such
settlement at least 30 days prior to such settlement being entered into, and
(iii) the Depositor shall not have reimbursed the Indemnified Party in
accordance with such request prior to the date of such settlement.

      The term "liability," as used in this Section 5.12, shall include any
losses, claims, damages, expenses (including without limitation the Trustee's
costs and expenses in defending itself against any losses, claims or
investigations of any nature whatsoever to the extent the Trustee is not
reimbursed as contemplated in this Section 5.12) or other liabilities, joint or
several, arising for any reason (including without limitation violation of
applicable laws or trademarks or service marks).

      The obligations of the Depositor under this Section 5.12 (i) shall be in
addition to any liability which the Depositor may otherwise have, (ii) shall
extend, upon the same terms and conditions, to each officer and director of the
Trustee and to each Person, if any, who controls the Trustee within the meaning
of the Securities Exchange Act of 1934, as amended and (iii) shall survive the
termination of this Agreement and the resignation or removal of the Trustee.

      Section 5.13. Undertaking for Costs. All parties to this Agreement agree,
and each Holder of any Certificate by such Holder's acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any
Proceeding for the enforcement of any right or remedy under this Agreement, or
in any Proceeding against the Trustee for any action taken, suffered or omitted
by it as Trustee, the filing by any party litigant in such Proceeding of an
undertaking to pay the costs of such Proceeding and that such court may in its
discretion assess reasonable costs, including reasonable attorneys, fees,
against any party litigant in such Proceeding, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.13 shall not apply to:

      (a) any Proceeding instituted by the Trustee;


                                      B-30
<PAGE>   41
      (b) any Proceeding instituted by any Holder, or group of Holders, in each
   case holding in the aggregate Outstanding Certificates representing more than
   10% of the Voting Rights; or

      (c) any Proceeding instituted by any Holder for the enforcement of the
   payment of Principal or Interest on or after the respective due dates
   expressed in such Certificate and in this Agreement (or, in the case of
   redemption, on or after the Redemption Date).

      Section 5.14. Charges and Expenses. Except as otherwise provided in this
Agreement, (i) no current or future charges, fees and expenses of the Trustee
shall be payable by or withheld from any Person other than the Depositor, except
for any taxes and other governmental charges, and (ii) in full payment and
satisfaction of all other charges and expenses of the Trustee (including, in
each case, fees and expenses of counsel) incidental to the performance of its
obligations hereunder, the Depositor shall pay the Trustee an amount determined
in accordance with a separate agreement between it and the Trustee. The Trustee
shall not be released from any of its duties hereunder as a result of the
failure of the Depositor to pay such amount.

      Section 5.15. Trustee Reports. So long as the Certificates are held in
DTC's book-entry only system, annual unaudited reports setting forth the amounts
of payments on the Certificates, and whether such amounts are principal or
interest shall be prepared by the Trustee and sent to DTC. To the extent the
Depositor fails to provide the Trustee with a copy of any report referred to in
Section 5.09(a) (i) or (iv) herein prior to the 10th Business Day preceding the
applicable filing date therefor as required by such provisions, the Trustee
shall request the Depositor to prepare and file such report and, if the
Depositor fails to do so, shall cause such report to be prepared and filed and
the Depositor shall reimburse the Trustee for its reasonable expenses incurred
in connection therewith. Any such expenses not reimbursed by the Depositor shall
be borne by the Holders.


                                   ARTICLE VI

                           HOLDERS' LISTS AND REPORTS

      Section 6.01. Depositor to Furnish Names and Addresses of Holders to
Trustee. The Depositor shall furnish or cause to be furnished to the Trustee not
more than five days before each Interest Payment Date or Redemption Date, and at
such other times as the Trustee may request in writing, a list, in such form as
the Trustee may reasonably require, to the extent such information is in the
possession or control of the Depositor or any of its paying agents, of the
Holders of Certificates as of the close of business on the applicable record
date of the underlying Bonds; provided, however, that so long as the Trustee
maintains the Certificate Register, no such list shall be required to be
furnished.

practicable, the names and addresses of the Holders of Certificates contained in
the most recent list furnished to the Trustee as provided in Section 6.01 and

its capacity as Certificate registrar. The Trustee may destroy any list

furnished.

312(b) with other Holders with respect to their rights under this Agreement or

                            AMENDMENT AND TERMINATION

      Section 7.01. Amendment. The form of the Certificates and any provisions
of this Agreement may at any time and from time to time be amended by agreement
between the Depositor and the Trustee in any respect which they may deem
necessary or desirable, provided that in no event shall any amendment defer or
alter the maturity of a Certificate, or in other manner adversely affect the
rights to payment of a Holder of a Certificate or otherwise materially prejudice
any substantial existing right of the Holders of the Certificates; and provided
further that at the time of any amendment the Trustee shall be provided evidence
that the rating on the Certificates by the Rating Agency will not be lowered or
withdrawn as a result of the amendment. Every Holder of a Certificate at the
time any such amendment so becomes effective shall be deemed to be continuing to
hold such Certificate, to consent and agree to such amendment and to be bound by
this Agreement as amended thereby. Prior to entering into any amendment to the
form of the Certificates or this Agreement, the Trustee shall be entitled to
receive an Opinion of Counsel to the effect that such amendments are authorized
or permitted by this Agreement and that all conditions precedent to the
execution and delivery of such amendments have been satisfied. The costs of
providing such Opinion of Counsel shall be borne by the Holders requesting that
the Trustee execute and deliver such amendment. The Trustee shall notify the
Holders of the estimated expense of any such Opinion of Counsel.

      Section 7.02. Termination. This Agreement shall terminate one year
following the payment upon maturity (or any earlier redemption) by the
respective Issuers of the entire principal amount (and any redemption premium)
of the Bonds or, in the event of a default on the Bonds, one year following
receipt by the Holders of all amounts to which the Holders are entitled pursuant
to Section 5.03(b) hereof. If any Certificates shall remain outstanding after
the date of termination of this Agreement, the Trustee shall not perform any
further acts under this Agreement, except that the Trustee shall hold the
proceeds of any payment, without liability for interest, for the pro rata
benefit of the Holders of Certificates which have not theretofore been
surrendered for payment unless otherwise required by applicable law. Upon the
termination of this Agreement, the Depositor shall be discharged from all
obligations under this Agreement except for its obligations to the Trustee under
Sections 5.14 and 5.12 hereof.

                           REDEMPTION OF CERTIFICATES

      Section 8.01. Redemption. If the Bonds are redeemed in whole or in part on
or after the First Call Date, upon actual receipt by the Trustee of notice of
such redemption, the Trustee shall, in accordance with the provisions of this
Article VIII, redeem a principal amount of Pooled Certificates, Callable
Principal Certificates or Callable Stripped Bond Certificates, as applicable,
equal to the principal amount of the Bonds of such issue held in trust hereunder
so redeemed, and if the Bonds are redeemed in part, then the Trustee shall
select the Certificates to be redeemed by lot in such manner as the Trustee
deems fair and appropriate. In the absence of the actual notice described in
this Section 8.01, the Trustee shall be under no obligation to effect the
redemption required by this Section 8.01. Upon redemption of any Certificate,
the Holder shall have no right to receive payments on any Interest maturing
after the Redemption Date.

      Section 8.02. Notice of Redemption. Notice of redemption shall be given by
the Trustee to each Holder of any Certificate to be redeemed as provided in
Section 9.04 hereof within thirty (30) days after notice of redemption of the
underlying Bonds has been given by the Issuer, trustee or paying agent of or for
the Bonds, as the case may be (but not less than fifteen days prior to the
redemption date); provided, however, that the Trustee shall not be required to
give any notice of redemption less than five (5) Business Days after the date it
receives notice of such redemption. All notices of redemption shall be mailed to
each Holder at such Holder's last address on the Certificate Register and shall
state the Redemption Date, the date the Certificates are to be redeemed, the
amount payable on such date, the place at which Certificates are to be
surrendered for payment and that interest on amounts redeemed shall cease to
accrue on and after the Redemption Date.

                              OFFICER'S CERTIFICATE
                   OF UNITED STATES TRUST COMPANY OF NEW YORK

      The undersigned, being a Senior Vice President of United States Trust
Company of New York (the "Bank"), does hereby certify and agree on behalf of the
Bank, for the benefit of PaineWebber Incorporated, Corporate Asset Backed
Corporation ("CABCO") and the beneficial owners of the Certificates (as defined
below), that:

   1. The Amended and Restated Trust Agreement dated as of June 14, 1999,
including the Standard Terms and Provisions of Series Trust Agreement (the
"Trust Agreement"), between CABCO, as Depositor (the "Depositor"), and United
States Trust Company of New York, as Trustee (the "Trustee"), has been duly
executed and delivered in the name of and on behalf of the Bank.

   2. Pursuant to the provisions of Section 2.01 of the Trust Agreement, the
Trustee has issued $25,000,000 face amount of Trust Certificates (the
"Certificates").

   3. The Bank is a state chartered bank and trust company organized under the
laws of the State of New York whose deposits are insured by the FDIC, and has
the power to act as trustee with respect to the Certificates.

   4. Immediately prior to the transfer of any of the Florida Power & Light
Company 7.05% First Mortgage Bonds due 2026 (the "Bonds") to the Trustee
pursuant to the Trust Agreement, the Trustee did not have record or beneficial
ownership of such Bonds.

   5. By means of separate recordation upon the books of the Trustee, or by
physical segregation, if appropriate, the Bonds will always be segregated and
kept separate from the assets of the Bank and from all other trust or fiduciary
accounts, and will always be specifically identified as property held subject to
a trust. The Trust Agreement will always be maintained as an official record in
the books and records of the Trustee. The Trustee will always hold the Bonds as
required by the Trust Agreement, will always keep its trust records separate and
distinct from its other records, will always ensure its trust records are
complete, will always comply with all applicable laws, regulations, and rules
relating to the custody of assets held in a trust relationship, and will always
take whatever steps are necessary to ensure that, should the superintendent of
banks for the State of New York (the "Superintendent") take possession of the
Trustee, or a receiver or liquidator for the Trustee be appointed, at such time
the Bonds would be identifiable as property held subject to the trust
relationship by the Trust Agreement. At all times that the Bonds are credited to
an account maintained on behalf of the Trustee at The Depository Trust Company
of New York, the Bank will reflect on its records that the Bonds are held in a
trust account subject to the Trust Agreement, which account will contain no
property of the Trustee in its individual capacity.


                                       D-1
<PAGE>   52
   6. At no time will the Bank receive a loan or other credit from a third
person because of such third party's reliance upon the Bank's apparent ownership
of the beneficial interests in the Bonds.

   7. Each person who, on behalf of the Bank, executed the Trust Agreement was
at the date thereof and is now duly authorized as a signatory of the Bank and
duly authorized to perform such acts at the respective times of such acts and
the signatures of such persons appearing on such documents are their genuine
signatures.

   8. The Trust Agreement has been duly and validly authorized, executed and
delivered by the Bank and is enforceable against the Bank in accordance with its
terms, except as the enforceability thereof may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and by general
principles of equity.

Ladies and Gentlemen:

      We have advised Corporate Asset Backed Corporation (the "Registrant") with
respect to certain federal income tax considerations in connection with the
issuance by CABCO Trust for Florida P & L First Mortgage Bonds (the "Trust") of
1,000,000 Trust Certificates, principal amount $25 per certificate (the
"Certificates"), issued pursuant to the Amended and Restated Trust Agreement,
dated as of June 14, 1999, including the Standard Terms and Provisions of Series
Trust Deposit Agreement incorporated therein by reference (the "Trust
Agreement"), between the Depositor and United States Trust Company of New York,
as Trustee (in such capacity, the "Trustee"). Such advice conforms to the
description of selected federal income tax consequences to holders of the
Certificates that appear under the heading "Certain Federal Income Tax
Considerations" in the prospectus dated March 18, 1999 and the prospectus
supplement dated June 7, 1999 (collectively, the "Prospectus"), forming a part
of Post-Effective Amendment No. 1 to the Registration Statement on Form S-3
(File No. 33-91744) filed by the Registrant with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Act") on May 9,
1995 (the "Registration Statement). Such description does not purport to discuss
all possible income tax ramifications of the proposed issuance, but with respect
to those tax consequences which are discussed, in our opinion the description is
accurate in all material respects.

      This opinion is based on the facts and circumstances set forth in the
Prospectus and in the other documents reviewed by us.
